Description

  The present invention relates to the technical field of smart trash cans, and more specifically, to a trash bag unit, a trash bag unit positioning mechanism, and a smart trash can.

  With the development of science and technology and the improvement of people's living standards, smart homes are becoming increasingly indispensable as part of everyday life. Among them, smart trash cans are attracting people's attention because of their clean, sanitary, and convenient use.

  In the prior art, the level of automation of smart trash cans is increasing, but the technology of fully automatic mounting and packaging is not yet complete. The cause is that the fully automatic loading and packaging technology of garbage bags depends on the combination of various components such as automatic loading device, automatic packaging device, garbage bag suitable for automatic loading and automatic packaging, garbage bag storage device, etc. Therefore, even if any of these elements are incomplete, it is not possible to realize automatic mounting and packaging of the garbage bag.

  Regarding garbage bags, there are several types of garbage bags that are currently commercially available, including handleless garbage bags, handbag-type garbage bags, and garbage bags with strings. Although it is in the form of a roll, some hand-held garbage bags use a flat folded package, and some of the small number of garbage bags use a type that can be taken out one by one. The common features of them are that the packaging volume is small and the manufacturing cost is low.However, plastic garbage bags are so flexible that simple machines can be used to take out and attach garbage bags. There is a drawback that the mounting of a new garbage bag cannot be completed unless the replacement garbage bag is manually put on the trash can. In addition, since the internal capacity of the garbage bag is constant, the amount of the garbage inside the garbage bag is usually smaller than the capacity of the garbage bag in order to satisfy the packaging requirements of the garbage bag. In a general garbage bag, only two-thirds of the garbage can be filled to close the mouth of the bag, which is disadvantageous for disposal of garbage. Easy and have a negative impact on the environment. It also leads to waste of resources such as garbage bags. For example, a garbage bag with a string can fully utilize the capacity space of the garbage bag, but since the capacity is limited, it is not possible to enclose a relatively large volume of garbage when used, and Since it is necessary to manually attach the bag, it is disadvantageous to perform automatic bag attachment.

  Regarding garbage bag storage devices, most of the trash can products currently on the market do not have a dedicated device for storing trash bags, and some of the few trash can products are located at the bottom or outside of the cylinder. However, only the storage device used for storing roll-shaped garbage bags is provided, and it is far from satisfying the need for fully automatic loading and packaging of garbage bags.

  Therefore, in order to easily realize full-automatic loading and packaging of garbage bags using a simple machine, how to store garbage bags, and how to increase the level of automation and smartness of trash cans Whether to further improve is an important technical problem to be solved by those skilled in the art.

  SUMMARY OF THE INVENTION In order to overcome at least some of the problems in related products, the present invention provides a trash bag unit applicable to a smart trash bin to facilitate full automatic loading and packaging of trash bags in the trash bin.

  An exemplary embodiment will now be described in detail, an illustration of which is illustrated in the drawings. In the following description of the drawings, the same numerals in different drawings indicate the same or similar elements unless otherwise specified. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present application. Rather, they are merely exemplary of an apparatus or method consistent with some aspects of the present application, as set forth in the following claims.

  Embodiments will be described below with reference to the drawings. The embodiments described below do not limit the contents of the invention described in the claims. In addition, all the contents of the configurations shown in the following embodiments are not limited to the essential contents as the means for solving the invention described in the claims.

Example 1
This specific embodiment provides a garbage bag unit of a smart trash can including a storage main body 1 and a lid 2 shown in FIGS. 1 to 5. The storage body 1 is provided with a first opening 11 that penetrates the storage body 1, the lid 2 is provided with a second opening 12, and dust is disposed between the first opening 11 and the second opening 12. The first opening 11 and the second opening 12 are provided corresponding to each other so as to pass through and enter the trash can. Here, the size and shape of the first opening 11 and the second opening 12 are not limited, and may be circular, square, or another shape.

  In the storage body 1, an annular concave groove 3 for storing the garbage bag 4 is provided so as to surround the outside of the first opening 11. Here, the annular concave groove 3 has an opening, and the opening direction may be directed to the direction of the first opening 11 or may be directed to the opposite direction to the first opening 11. The opening direction of the hole 11 may coincide with the opening direction. Since the size of the annular groove 3 is related to the storage amount of the garbage bag 4, the annular grooves 3 having different sizes can be provided in accordance with a use situation and a use density. When the used amount of the garbage bag 4 is relatively large, the annular groove 3 having a relatively large capacity can be provided, and in the opposite case, the annular groove 3 having a relatively small capacity can be provided.

  The cover 2 covers the opening of the annular groove 3. When the lid 2 covers the opening of the annular groove 3, the garbage bag 4 is retained in the annular groove 3 and is an annular gap formed by the lid 2 and one side wall of the annular groove 3. The trash bag 4 can be pulled out only through the trash bag outlet. The size of the gap is not limited, and may be any size as long as the function can be realized.

  In use, the annular garbage bag 4 is inserted into the annular groove 3, and the opening at one end of the garbage bag 4 is pulled out from the outlet of the garbage bag and closed. Thus, when the trash bag needs to be replaced, the trash bag 4 receives a strong atmospheric pressure and is pushed into the trash box by the action of the vacuum device as long as the vacuum device inside the trash box is activated. Automatic loading of garbage bags is completed. When packaging or heat sealing of the garbage bag 4 is necessary, simply operating the automatic wrapping mechanism causes the garbage bag 4 to be pushed into the heat welding device by the action of the press bar. Done.

  The structure of the storage body 1 and the lid 2 not only restricts the degree of freedom of movement of the trash bag 4 so that the trash bag 4 can be moved in only one direction, but also fixes the form of the trash bag 4, Since the garbage bag 4 can always be kept in the opened state, the step of expanding the garbage bag from the automatic garbage bag mounting process can be omitted, and the automatic mounting and packaging mechanism of the garbage bag can be greatly simplified and realized. And the operation can be simplified.

  With such an installation, the garbage bag unit can be applied to a smart garbage bin, whereby a fully automatic loading and packaging function of the garbage bag is easily realized, and the level of automation and smartization of the garbage bin is improved. It can be further improved. Further, the occurrence of breakage of the garbage bag during the manufacturing, storage and transportation processes is effectively prevented. The size of the annular groove 3 can be set to different sizes according to the usage density of the trash box and the scene in which it is used, and it is easy to adjust the storage capacity and the packaging length of the trash bag in the container, Resources can be saved. Compared to the case where the trash bags are replaced in units of rolls, the replacement of the trash bags is much easier, which improves the efficiency. The garbage bag unit has an integrated structure, is easy to assemble, and is advantageous in reducing manufacturing and installation costs.

  In addition, the fixing method of the lid 2 covering the opening of the annular groove 3 is such that the lid 2 is directly connected to the storage main body 1 and the lid 2 rotates with the storage main body 1 via one side. It may be a system that can be connected to form an integrated structure. In this way, the stability and reliability of the garbage bag unit can be guaranteed. As shown in FIG. 12, the lid 2 and the storage body 1 may be removably connected. By doing so, when attaching the garbage bag, the lid 2 can be completely removed, and the attachment of the garbage bag becomes easy. Of course, other fixing methods may be used.

  The garbage bag unit further includes a garbage bag 4 adapted to the storage main body 1 and capable of being inserted into the annular groove 3 of the storage main body 1. Here, the garbage bag 4 has a cylindrical structure in which the entire inside is penetrated, and may have a form in which both ends have openings, or a form in which one end has an opening and the other end is closed. The garbage bag 4 can be folded in a bellows shape along its axial direction so as to be folded into an annular shape, and the size of the annular shape is such that it can be inserted into the annular groove 3. And the size of the annular groove 3. The length of the garbage bag 4 is not limited because the garbage bag 4 is of an integral type and does not have a perforation. Can be charged.

  The method of folding the garbage bag 4 in a bellows shape is the method shown in FIGS. 4 and 5, and the folding direction may be perpendicular to the side wall of the annular groove 3 or parallel to the side wall of the annular groove 3. The direction may be other directions depending on the specific situation.

  When the garbage bag 4 is used, the garbage bag 4 having a certain length and diameter can be cut out as needed. An integrated cylindrical garbage bag having no perforations is annularly folded along its axial direction by hand or with a certain tool, and the folded annular garbage bag 4 is inserted into the annular groove 3 of the storage body 1. , The charging of the garbage bag 4 is completed. Further, by placing the garbage bag unit in which the garbage bag is loaded in the corresponding structure at the corresponding position of the trash box, it is possible to use the integrated cylindrical garbage bag without this perforation. Naturally, one end of the trash bag 4 pushed into the annular groove 3 may be pulled out and sealed. Here, the sealing method may be heat sealing, but is not limited to heat sealing, and may be another sealing method that facilitates automatic use of the first garbage bag. , And the automatic packaging mechanism may perform automatic packaging and sealing.

  By such an installation, the garbage bag unit is basically not restricted as compared with the conventional garbage bag, and more garbage can be enclosed. In addition, the packaging position can be independently selected according to the amount of garbage, and the remaining length of garbage bags can be used continuously. Waste of the resources of bags can be prevented, automatic packaging and automatic garbage bag exchange can be easily realized, and the level of automation and smartness of conventional smart trash cans can be improved.

  In this embodiment, as shown in FIG. 3, a folded edge structure 5 is provided on one side wall edge of the annular groove 3 surrounding the outlet of the garbage bag, and the folded edge structure 5 is located outside the annular groove 3. Will be folded back towards. Thus, when the garbage bag 4 is pulled out from the garbage bag outlet, the folded edge structure 5 not only functions as a guide to the garbage bag 4 but also prevents damage to the garbage bag 4 due to scratching, thereby wasting resources. Can be reduced.

  In some embodiments, the opening direction of the annular groove 3 and the opening direction of the first opening 11 match. In this case, the two side walls surrounding the annular groove 3 are an inner wall and an outer wall, and the inner wall is located on one side close to the first opening 11, and the inner space of the first opening 11 and the annular groove 3 The outer wall is located on one side away from the first opening 11, and can separate the annular groove 3 from the external space. As a result, the opening of the annular groove 3 and the circumferential length of the internal space are substantially the same, so that the garbage bag 4 can be easily inserted, and the connection between the annular groove 3 and the lid 2 is more stable. This improves the level of integration of the garbage bag unit.

  Since the lid 2 has a structure having the second opening 12, the lid 2 has an inner edge close to the second opening 12 and an outer edge remote from the second opening 12. Here, a gap is formed between the inner edge of the lid 2 and the inner wall of the annular groove 3 to form an outlet for the garbage bag, and the outer edge of the lid 2 and the outer wall of the annular groove 3 are connected to each other. Thereby, one end of the garbage bag 4 can be pulled out from the gap at the outlet of the garbage bag and closed. When the trash bag is mounted, the outside air pushes the trash bag 4 into the trash box through the second opening 12 and the first opening 11. At this time, the trash bags 4 can be sequentially pulled out from the exit portion of the trash bag. As a result, waste of garbage bag resources can be reduced, and furthermore, the garbage bag can be kept in an expanded state, so that the step of expanding the garbage bag in the garbage bag mounting process can be omitted, and It facilitates fully automatic bag mounting and packaging functions, and further enhances the level of trash bin automation and smartness.

  Of course, in another embodiment, the inner edge of the lid 2 is connected to the inner wall of the annular groove 3, and a gap is provided between the outer edge of the lid 2 and the outer wall of the annular groove 3 so that the outlet of the garbage bag can be removed. May be formed. The obtained beneficial effects are almost the same as the above-mentioned effects, and thus the description is omitted.

  One side of the outer edge of the lid 2 is rotatably connected to the outer wall of the annular groove 3. Here, the rotatable connection may be a connection via a rotating shaft, a connection fixed using a fold, or of course, any other rotatable connection type. Good. Thus, when the garbage bag 4 is to be put into the annular groove 3, the opening of the annular groove 3 can be opened by rotating the lid 2, and the garbage bag 4 is removed from the annular groove 3. When the cover 2 is to be held inside, the opening of the annular groove 3 can be covered by rotating the lid 2, so that the structure is simple and easy to realize, and it is useful for improving the stability of the structure. I do.

  Further, a bent structure 6 is provided on the outer edge of the lid 2. The bent structure 6 faces the outer wall of the annular groove 3, and the bent structure 6 is tightly fitted to the outer wall. As a result, the lid 2 is firmly attached to the opening of the annular groove 3 by the interference fitting structure, and the stability of the structure can be improved. Of course, the folding structure 6 and the outer wall may be engaged with each other by a buckle structure, so that the level of integration of the trash bag unit can be further improved and the trash bag unit can be easily attached and detached.

  Here, the buckle structure may include a locking groove and a locking block that engage with each other. One of the locking groove and the locking block is installed inside the bent structure 6, and the other is installed on the outer wall of the annular groove 3. When the bent structure 6 is located near the outer wall of the annular groove 3, the locking block is fitted inside the locking groove to realize locking. Such installation facilitates the realization of the buckle structure, simplifies the operation, and improves the connection stability between the lid 2 and the storage body 1.

  In some embodiments, the overall shape of the storage body 1 and the lid 2 is a rectangular ring-shaped structure in which each corner is chamfered. Since many trash cans are rectangular, such an installation can make the application to a rectangular trash can easier, and the connection with the trash can can be made more rigid, so that the trash bag unit can be used. Rotation and movement in the trash can can be effectively prevented. The shape of the garbage bag unit is not limited to a square ring, but may be a circular ring or other shapes.

  The structures of the storage main body 1 and the lid 2 may be formed of a plastic material, may be formed by folding and corrugating a corrugated cardboard, or may be formed by folding and bending metal. This facilitates the acquisition and processing of the material, and can meet the requirements in various situations. Of course, other materials may be used depending on the specific situation.

  The garbage bag unit will be specifically described based on the contents of the above-described embodiment and preferred embodiments thereof.

  The present application provides a trash bag unit that employs a container-type structure (that is, a garbage bag container) including an opening in the center and that always passes through the opening in the center and falls into the trash bag 4. The container type structure can be divided into a lid 2 and a storage main body 1 in form, and the storage main body 1 is provided with an annular concave groove 3 for inserting a garbage bag 4, and the lid 2 has an annular shape. It covers the opening of the concave groove 3 and is integrally connected to the storage body 1. Here, the shape of the lid 2 and the storage main body 1 may be square or circular, and can be specifically changed according to the shape of a trash can using this structure. The container-type structure (that is, the garbage bag container) may be an integrated structure composed of only one component, and the lid 2 is rotatably connected to the storage body 1 via one side. The lid 2 and the storage body 1 may be separated into two parts and assembled for use. The lid 2 may be installed to hold the garbage bag 4 in the storage body 1 with a tape, a metal wire, or other combination. The lid 2 and the housing body 1 may be formed of a plastic material, may be formed by folding and corrugating a corrugated cardboard, or may be formed by folding and bending metal. An annular gutter (i.e., a folded edge structure) is provided on the inner wall of the annular groove 3 of the storage body 1, but the position of the annular gutter is not limited to the inner wall of the annular groove 3, but may be an outer wall or other position. May be distributed.

  Further, it includes an integral cylindrical garbage bag 4 having no perforation. One end of the garbage bag 4 may be sealed, or both ends may be unsealed, to facilitate automatic removal when first used after being replaced with a new garbage bag 4. When charged for use, the garbage bag 4 is folded in a bellows shape along its axial direction by hand or by machine into an annular shape, and is put into the storage body 1. Here, the storage body 1 is generally a container-type structure having an opening, but is not limited to the container-type structure, and may be a groove-like structure, an annular structure, or a corresponding fixed rack structure. In normal use, the trash bag 4 is generally stored at an upper position inside the trash box, but may be stored at an arbitrary position inside the trash box. In particular, the garbage bag 4 folded in a ring is generally arranged so as to be parallel to the entrance of the trash can.

The steps of assembling the garbage bag unit include:
Manually or by means of a tool, the unperforated cylindrical garbage bag 4 is axially folded into an annular shape, the length and diameter of the garbage bag 4 being customized according to the requirements of use. ,
Pushing the folded annular garbage bag 4 into the storage area of the garbage bag 4 formed inside the annular groove 3;
This is a step of pulling out one end of the cylindrical garbage bag 4 pushed into the annular groove 3 and sealing it. The sealing method is a heat sealing method. However, the sealing method is not limited to heat sealing. A step of using another sealing method that makes it easy to automatically take out the garbage bag 4;
Turning the lid 2 to cover the opening of the annular groove 3 of the storage body 1. Since the lid 2 is provided with the bent structure 6, the lid 2 and the storage body 1 can be quickly coupled. Thus, the assembly work of the garbage bag unit is completed.

  The present application further provides a smart trash can including the trash bag unit described in the previous embodiment. Such a smart trash can can easily realize a fully automatic loading and packaging function of the trash bag, and further improves the level of automation and smartness of the trash can. Further, the occurrence of breakage of the garbage bag 4 during the manufacturing, storage and transportation processes is effectively prevented. The size of the annular groove 3 can be set to different sizes according to the usage density of the trash can and the scene in which it is used, so that the accommodation amount and the packaging length of the trash bag 4 in the container can be easily adjusted, Can be saved. As compared with the case where the trash bags are replaced in units of rolls, the replacement of the trash bags is easier and the efficiency is improved. The garbage bag unit has an integrated structure, is easy to assemble, and is advantageous in reducing manufacturing and installation costs. This beneficial effect is substantially similar to that of the above-described garbage bag unit, and thus the description is omitted.

  Preferably, as shown in FIG. 13, the storage main body 1 and the cylindrical body of the smart trash can have an integrated structure. That is, the storage body 1 and the trash box body 14 are integrally formed, and the press cover 16 serves as a lid of the trash bag unit.

Example 2
As shown in FIGS. 6 to 11, the smart trash can further includes a trash bag unit positioning mechanism. Here, the trash bag unit 10 includes a trash bag container and a trash bag 4 (see FIGS. 4 and 5) loaded in the trash bag container. The trash bag container is installed in the trash box main body 14. A third opening 13 is provided in the trash bag container to allow the trash to pass so as not to affect the input of the trash into the trash box. A storage rack 15 for supporting the garbage bag container is further installed in the trash box main body 14, and the storage rack 15 is provided with a third opening 13 in order to smoothly put trash into the trash box main body 14. A corresponding fourth aperture 17 is provided. In order to facilitate replacement of the trash bag container, the trash box body 14 is further provided with a passage for taking in and out the trash bag container.

  Those skilled in the art will readily understand that the trash bag unit 10 may be configured to include only a trash bag container. It is not necessary to assemble and sell the trash bag 4 together with the trash bag container, and the user may purchase the trash bag 4 separately and attach it to the trash bag container at the time of use.

  Further, the passage may be provided on the top or side of the trash can body 14. If the passage is provided at the top of the trash box body 14, the used trash bag container is taken out along the height direction of the trash box body 14, and then a new trash bag container is put into the storage rack 15 along the opposite direction. I just need. When the passage is provided on the side of the trash box main body 14, the storage rack 15 is pulled out from one side of the trash box, the used trash bag container is taken out, and then a new trash bag container is put into the storage rack 15, What is necessary is just to push in the trash box main body 14 along an opposite direction.
