As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Please also refer to FIG. 1 , the present invention provides a vacuum cleaner 10 . The vacuum cleaner 10 includes a filter device 11 , an exhaust device 13 , a power supply device 15 , and a grip portion 17 . The power supply device 15 drives the exhaust device 13 to work, so as to form a negative suction pressure in the filter device 11 , so that the external air flow enters the filter device 11 . The filter device 11 is used to filter dust and impurities in the airflow. The gripping portion 17 is used to facilitate the user's grip. In some embodiments, the holding portion 17 is a hollow structure, and a controller is disposed in the holding portion 17 . The controller is electrically connected to the exhaust device 13 and the power supply device 15 , and a control button 170 is disposed on the periphery of the holding portion 17 . When the vacuum cleaner 10 is working, the control button 170 is pressed, and the controller controls the power supply device 15 to drive the exhaust device 13 to work. After the cleaning is finished, the control button 170 is pressed again, and the vacuum cleaner 10 stops working.

The exhaust device 13 and the power supply device 15 are opposite to each other and are provided at opposite ends of the filter device 11 at intervals, and the air flow exchange can be performed between the exhaust device 13 and the filter device 11 . The grip portion 17 is connected between the exhaust device 13 and the power supply device 15 . Taking the axis of the grip portion 17 as a reference, both ends of the axis of the grip portion 17 respectively pass through the power supply device 15 and the exhaust device 13 .

Specifically, in the vacuum cleaner 10, the exhaust device 13 and the power supply device 15 are the main weight components of the vacuum cleaner 10, and the grip portion 17 is connected between the exhaust device 13 and the power supply device 15, so the weight of the vacuum cleaner 10 can be relatively uniform are distributed at both ends of the grip portion 17 , so that the center of gravity of the vacuum cleaner 10 is relatively close to the grip portion 17 . On the other hand, taking the axis of the grip portion 17 as a reference, both ends of the axis pass through the power supply device 15 and the exhaust device 13 respectively. Therefore, the weight of the vacuum cleaner 10 can be more evenly distributed on both sides of the holding portion 17 , so that the center of gravity of the vacuum cleaner 10 is closer to the holding portion 17 . Therefore, the vacuum cleaner 10 can be held with less effort and can be held conveniently.

When the gripping portion 17 is connected between the exhaust device 13 and the power supply device 15 , in some embodiments, the gripping portion 17 is inclined relative to the exhaust device 13 and the power supply device 15 , and the gripping portion 17 is connected to the power supply device 15 . The distance from one end of the grip portion 17 to the filter device 11 is greater than the distance from the end of the grip portion 17 connected to the exhaust device 13 to the filter device 11 . That is, the end of the grip portion 17 connected to the exhaust device 13 is closer to the filter device 11 than the end of the grip portion 17 connected to the power supply device 15 . This design conforms to the ergonomic setting, which is convenient for users to hold and saves effort when holding.

In other embodiments, the holding portion 17 can also be disposed vertically to the exhaust device 13 and the power supply device 15 .

Please refer to FIG. 2 and FIG. 3 together. The filter device 11 includes a housing 110 and a filter element 112 accommodated in the housing 110 . Specifically, the housing 110 has a housing inner cavity 1101 , and the filter assembly 112 is accommodated in the housing inner cavity 1101 . The exhaust device 13 includes an exhaust housing 130 having an exhaust cavity 1301 , an exhaust element 132 and a power assembly 134 for providing electric drive for the exhaust element 132 . The exhaust element 132 and the power assembly 134 are both accommodated in the exhaust cavity 1301 . The power supply device 15 includes a power supply housing 150 having a power supply cavity 152 and a power supply assembly 154 accommodated in the power supply cavity 152 . The exhaust housing 130 and the power supply housing 150 are respectively connected to opposite ends of the housing 110 and located on the same side of the housing 110 to form the entire housing of the vacuum cleaner 10 by splicing. Specifically, the housing 110 , the exhaust housing 130 and the power supply housing 150 may be integrally formed or separately formed.

In the vacuum cleaner 10 , the power supply housing 150 is generally arranged at the bottom of the entire vacuum cleaner 10 , and the exhaust housing 130 is arranged at intervals relative to the power supply housing 150 and is located at the top of the entire vacuum cleaner 10 . The housing 110 is located on the left side of the vacuum cleaner 10 , and the grip portion 17 is generally located on the right side of the vacuum cleaner 10 according to the principle that the user generally operates with the right hand.

The outer wall of the casing 110 is provided with an air inlet 1102 which communicates with the inner cavity 1101 of the casing. The air inlet pipe 114 is connected to the air inlet 1102 and communicates with the air inlet 1102 to form an air inlet passage 1141 . The exhaust cavity 1301 of the exhaust housing 130 communicates with the inner cavity 1101 of the housing 110 , and the exhaust housing 130 is provided with an exhaust port 1303 that communicates with the exhaust cavity 1301 . The power supply chamber 152 is isolated and independent from the dust removal chamber and the exhaust chamber 1301 . Therefore, the power supply component 154 accommodated in the power supply cavity 152 can be isolated from external moisture and dust, so as to maintain the normal operation of the power supply component 154 . In addition, when the power supply assembly 154 is disposed in the power supply cavity 152, the weight of the entire power supply device 15 can be increased. Therefore, the power supply device 15 can be used as a supporting body of the entire vacuum cleaner 10 . When the vacuum cleaner 10 is not in use, the power supply device 15 is operated to be in contact with the installation surface (eg, the ground, a desktop, etc.), so that the entire vacuum cleaner 10 can be stably installed on the installation surface.

In some embodiments, the exhaust housing 130 and the power supply housing 150 are arranged in parallel, and both the exhaust housing 130 and the power supply housing 150 are arranged perpendicular to the housing 110 , so the appearance of the entire vacuum cleaner 10 is more regular and more beautiful. In this specific embodiment, the housing 110 is arranged vertically, and the exhaust housing 130 and the power supply housing 150 are both arranged horizontally. (The horizontal and vertical orientations mentioned in the present invention are all based on the horizontal and vertical orientations of the vacuum cleaner 10 shown in FIG. 1 , that is, the state when the vacuum cleaner 10 is normally placed on a horizontal plane).

In some other embodiments, the exhaust housing 110 and the power supply housing 150 may also be disposed obliquely.

The power component 134 is electrically connected to the power supply component 154, and the power component 134 forms a negative pressure suction force in the housing cavity 1101 and the exhaust cavity 1301 under the driving of the power supply component 154, so that the air in the external environment forms an airflow into the housing cavity 1101, and flows from the housing cavity 1101 to the exhaust cavity 1301 after passing through the filter assembly 112. The filter assembly 112 is used to filter the air flow with dust and sundries, and the filtered dust and sundries are collected in the housing cavity 1101 . The exhaust member 132 is used to filter the airflow again before the airflow is discharged from the exhaust port 1303, and to re-exhaust the filtered clean airflow into the external environment.

The power assembly 134 is located between the filter assembly 112 and the exhaust 132 .

That is, the power assembly 134 is closer to the filter assembly 112 than the exhaust member 132 . Therefore, the air flow filtered by the filter assembly 112 has a shorter path to the power assembly 134 . The shorter path results in less wind loss and less momentum decay during the airflow to the power assembly 134 . Furthermore, the airflow can still flow toward the exhaust element 132 at a relatively high speed, and is discharged to the outside environment from the exhaust port 1303 after being filtered by the exhaust element 132 . The flow speed of the air flow is fast, which can accelerate the exchange speed between the air flow in the vacuum cleaner 10 and the outside, thereby effectively improving the working efficiency of the entire vacuum cleaner 10 .

Further, the air inlet end of the power assembly 134 is matched with the air outlet end of the filter assembly 112 .

The air inlet end of the power assembly 134 is connected to the air outlet end of the filter assembly 112, which can further shorten the air flow path between the filter assembly 112 and the power assembly 134, so that the wind loss of the air flow is smaller, and the working efficiency of the vacuum cleaner 10 can be further improved. improve. Specifically, the air inlet end of the power assembly 134 is connected to the air outlet end of the filter assembly 112 . It can be understood that the power assembly 134 is located outside the filter assembly 112 , and the air inlet end face of the power assembly 134 is connected to the air outlet end of the filter assembly 112 . The end faces are abutted, so that the power assembly 134 and the filter assembly 112 overlap only at the end face of the air inlet end of the power assembly 134 and the end face of the air outlet end of the filter assembly 112 . Alternatively, the air inlet end of the power assembly 134 and the air outlet end of the filter assembly 112 may also be sleeved, so that the power assembly 134 and the filter assembly 112 have more overlapping parts. Specifically, the connection between the air inlet end of the power assembly 134 and the air outlet end of the filter assembly 112 can be understood as the fact that the air inlet end of the power assembly 134 protrudes into the filter assembly 112 through the air outlet port of the filter assembly 112, or the filter assembly The air outlet end of 112 protrudes into the power assembly 134 through the air inlet port of the power assembly 134 .

Furthermore, the air outlet end of the filter assembly 112 is sleeved with the air inlet end of the power assembly 134 .

Therefore, the air flow from the air outlet end of the filter assembly 112 can directly enter the power assembly 134, so that the air flow path between the filter assembly 112 and the power assembly 134 is the shortest, the air flow has the smallest wind loss, and the entire vacuum cleaner 10 has a high work efficiency.

The axis (b-b) of the power assembly 134 passes through the air outlet end of the filter assembly 112 and the air inlet end of the power assembly 134, the axis (a-a) of the filter assembly 112 and the axis of the power assembly 134 are arranged at an included angle, and the included angle (∠ β) is less than or equal to 90 degrees.

Specifically, the intake direction of the intake end of the filter assembly 112 (as shown by arrow c in FIG. 2 ) is perpendicular to the extension direction (Y direction) of the axis (a-a) of the filter assembly 112 . Under the action of the power assembly 134 , the air outlet direction of the air outlet end of the filter assembly 112 (as shown by the arrow d in FIG. 2 ) and the air intake direction of the air inlet end of the power assembly 134 (as shown by the arrow d in FIG. 2 ) are related to the axis of the power assembly 134 ( The extending directions (X direction) of b-b) are the same. The airflow direction (as shown by arrow e in FIG. 2 ) of the airflow in the filter assembly 112 between the intake end and the exhaust end is the same as the extension direction (Y direction) of the axis (a-a) of the filter assembly 112 . The angle between the axis (a-a) of the filter assembly 112 and the axis (b-b) of the power assembly 134 can be understood as the angle between the airflow direction of the filter assembly 112 at the air inlet end and the air outlet end and the air outlet direction of the air outlet end of the filter assembly 112 (∠β), alternatively, can also be understood as the included angle (∠β) between the airflow directions of the air inlet and outlet ends of the filter assembly 112 and the air intake direction of the intake end of the power assembly 134 . By setting the axis (a-a) of the filter assembly 112 and the axis of the power assembly 134 (b-b) at an included angle (∠β), and the included angle (∠β) is less than or equal to 90 degrees, the airflow only needs to rotate after passing through the filter assembly 112 A smaller angle can enter into the intake end of the power assembly 134 , thereby effectively reducing the turning resistance of the airflow, so that the airflow still maintains a relatively fast flow rate, so as to improve the working efficiency of the vacuum cleaner 10 .

The power assembly 134 and the exhaust member 132 are arranged at intervals along the axial direction of the power assembly 134 .

Generally, the power assembly 134 generates sound waves during operation, and the sound waves are propagated by the flow of the air flow. In the present application, by arranging the power assembly 134 and the exhaust member 132 to be spaced apart, the propagation path of the sound wave in the exhaust cavity 1301 increases, and the contact frequency of the sound wave with the inner wall of the exhaust housing 130 will increase. The sound wave continuously collides with the inner wall of the exhaust cavity 1301, which causes the momentum of the sound wave to be greatly attenuated and the decibel number of the sound wave to weaken. Furthermore, the noise of the sound waves discharged from the exhaust port 1303 is small, and the user experience of the vacuum cleaner 10 is also improved accordingly.

It should be noted that, in some other embodiments, the power assembly 134 and the exhaust member 132 may also abut.

Referring to FIG. 2 again, the filter assembly 112 includes a dust removal element 1121 , a separation element 1123 and a filter element 1125 which are engaged in the inner cavity 1101 of the housing. The dust removal element 1121 , the separation element 1123 and the filter element 1125 are sequentially arranged along the axial direction of the filter assembly 112 , from the bottom to the top of the housing cavity 1101 , and the separation element 1123 communicates between the dust removal element 1121 and the filter element 1125 . The external air flows through the intake passage 1141 , the dust removal element 1121 and the separation element 1123 in sequence, and the air flow separated by the separation element 1123 enters the filter element 1125 and flows into the power element 134 from the outlet end of the filter element 11 . The dust removal element 1121, the separation element 1123 and the filter element 1125 can all be used to separate gas and dust. .

Please refer to FIG. 4 , FIG. 5 and FIG. 9 at the same time, the dust removal member 1121 is a cylindrical filter screen. The dust removal member 1121 is hollow to form a dust removal chamber 11210. The side wall of the dust removal member 1121 is provided with a dust removal hole 11212, and the separation member 1123 is provided with a separation channel 11230. The dust removal hole 11212, the dust removal chamber 11210 and the separation channel 11230 are connected in sequence. Specifically, the dust removal chamber 11210 refers to a space surrounded by a filter screen, and the space belongs to a part of the inner chamber 1101 of the housing. The filter element 1125 includes a filter body 11250 and at least two windshield walls 11252 disposed on the outer periphery of the filter body 11250. The filter body 11250 is hollow to form a collection cavity 11253. The at least two windshield walls 11252 are arranged along the circumference of the filter body 11250 and filter The outer periphery of the main body 11250 is divided to form an air inlet area 11254 and an air outlet area 11255 which are independent of each other. The air flow is filtered once by the air inlet area 11254 and then filtered again by the air outlet area 11255, and is discharged by the exhaust device 13.

The specific flow paths of the airflow flowing into and out of the housing cavity 1101 will be explained below through specific descriptions. Please refer to FIG. 3 and FIG. 6 at the same time, under the action of the power component 134, the airflow entering the inner cavity 1101 of the housing from the intake passage 1141 passes through the dust removal hole 11212, the dust removal chamber 11210 and the separation passage 11230 in sequence. Then, the air flow separated by the separation channel 11230 of the separation element 1123 enters the collection cavity 11253 from the air inlet area 11254 , and then flows into the air inlet end of the power assembly 134 through the air outlet area 11255 . When the airflow passes through the dust removal hole 11212 , the dust and sundries with larger particle size are separated from the airflow and collected at the bottom of the inner cavity 1101 of the housing. Then, the airflow flows into the separation channel 11230 from the dust removal chamber 11210 in the direction toward the top of the housing inner chamber 1101 . Specifically, the separation member 1123 is a cyclone separator, and the separation channel 11230 is formed by surrounding the inner wall of the conical structure. The side wall of the tapered structure is provided with an air inlet 11232, and the air flow flows into the separation channel 11230 from the air inlet 11232, and the air flow and the dust and impurities with small particle size are separated in the separation channel 11230.

Please also refer to FIG. 7 , the filter assembly 112 further includes a dust collecting member 1127 , and the dust collecting member 1127 passes through the dust removal cavity 11210 . The opposite ends of the dust collector 1127 abut with the bottom of the housing cavity 1101 and the end of the conical structure facing the bottom of the housing cavity 1101 respectively, so as to support the separation piece 1123 and position itself. One end of the dust collector 1121 facing the separating member 1123 is provided with a dust collecting hole 11270 , and a dust collecting cavity 11272 is formed inside the dust collecting member 1127 . Therefore, the dust and sundries with smaller particle size separated from the separation channel 11230 can be collected in the dust collection cavity 11272 from the dust collection hole 11270 . The airflow separated by the separation channel 11230 continues to flow, and flows through the air inlet area 11254, the collection cavity 11253 and the air outlet area 11255 in sequence, and then flows into the air intake end of the power assembly 134, and passes through the exhaust piece 132. 1303 discharge. The air inlet area 11254 and the air outlet area 11255 filter the airflow for the first time and the second time, respectively, and the dust and sundries separated in the air inlet area 11254 can fall onto the separator 1123 or be collected at the bottom of the housing cavity 1101 and many more. The dust and sundries separated in the outlet area can be collected in the collection chamber 11253 . Compared with the traditional filter element 1125 , the filter element 1125 in the present application can filter the air flow twice, so that the vacuum cleaner 10 and the filter device 11 thereof have a better air-dust separation effect. The setting of the wind blocking wall 11252 can prevent the airflow passing through the air inlet area 11254 and the air outlet area 11255 from channeling, so that the air flow must pass through the air inlet area 11254 when passing through the filter element 1125 before it can flow through the air outlet area. 11255, in order to ensure that the vacuum cleaner 10 and the filter device 11 have a better gas and dust separation effect.
