Description

[Detailed description of the invention] (Field of application of the invention) This invention relates to a space air purifying device that purifies indoor air. Specifically, the invention relates to a space air purifying device that purifies indoor air. The invention relates to a device used in such a manner.

(Background of the invention) Deodorizers, fragrances, etc. conventionally used for purposes such as cleaning the air in spaces are generally solid or liquid, and spray-type fragrances have also been provided. There is.

However, in this type of spatial air purifying device, when a relatively large amount of space ventilation is performed, there is little diffusion of fragrance from solid substances,
Further, in the case of the spray method, there is a problem that it is not suitable because it requires frequent manual spray pressing operations.

(Purpose of the invention) The present invention has been made from the above-mentioned viewpoints, and its purpose is to continuously produce the necessary and sufficient amount of water using a simple mechanical device without requiring frequent manual work. An object of the present invention is to provide a space air purifying device having a function of discharging and supplying fragrances and the like into a space.

(Summary of the invention) The feature of the space air purifying device of the present invention, which was made to achieve this purpose, is that a small amount of the space air purifying liquid containing fragrance etc. is poured into the bottom part. A vertical cavity-shaped main container that is filled with water and whose top is open to the outside, a thin cylindrical suction pipe that is provided to be able to suck up the filled liquid from the bottom of the main container, and the upper end of this suction pipe. A suction liquid diffusion section inside the main container that is bent to open in a generally horizontal direction, and an air discharge that suctions and diffuses the liquid by applying an upward jet air flow to the diffusion section. a tube, and at least one passage restriction portion located between above the diffusion portion and the top opening inside the main container and contacted by the gas flow containing the vaporized liquid vapor or mist. It's everywhere.

(Embodiments of the invention) The invention will be described below based on embodiments shown in the drawings.

FIG. 1 shows a perspective external view of an embodiment of a space air purifying device according to the present invention, and FIG. 2 shows a longitudinal sectional view thereof. In these figures, 1 is a main body container, which has a generally hollow cylindrical shape as a whole, and has a closed bottom and an open top. 2 is a lid for closing the top as necessary. Reference numeral 3 denotes a supporting bottom rod-shaped portion for fitting the main container into a hole of a fixing portion (not shown) and fixedly supporting the main container.

Reference numeral 4 denotes a thin cylindrical suction tube for sucking up the filling liquid provided at the internal bottom of the main container 1, and its upper end is formed to be even thinner and bent to open its upper end opening in a generally horizontal direction. As a result, a tube structure is formed in which a diffusion section 6 is formed in the vicinity of the opening.

Reference numeral 5 designates an air discharge pipe that introduces jet air from the outside and causes the jet air to flow upward through the vapor diffusion section 6, and supplies pressurized air from an external pressure air supply source (not shown) to the vapor diffusion section. 6 functions to promote the suction force for sucking up the liquid into the inside of the suction tube 4 and the diffusion of the suction liquid from the upper end port of the suction tube 4.

Reference numeral 7 denotes a first passage restriction section provided at the upper side of the diffusion section 6, and the jet air flowing upward in the diffusion section 6 is directed to the upper end of the suction pipe facing the diffusion section 6. When the sucked up liquid is diffused and the vapor or mist of the liquid is distributed to the upper process,
When this gas comes into contact with the wall of the first passage restricting portion 7, the excess gas condenses on the wall surface.
The degree of removal of the vaporized liquid due to dew condensation is determined by the discharge pressure of the jet air and the degree of restriction of the first passage restricting portion 7. In addition, in this example, the first
Further above the passage restricting part 7, there is a second passage restricting part 8.
is provided to suppress the amount of vaporized liquid such as perfume in the gas flowing upward. In this example, the first passage restricting part 7 is formed as a vertical wall surface at the tip of a protrusion projecting inward from the main container, and the second passage restricting part 8 is formed by forming four parts on a narrow part of the container main body itself. Although it is formed by providing hemispherical protrusions, it is not limited to these shapes.

Next, the functions of the space air purifying device as described above will be explained.

First, the lid 2 of the main container shown in FIG. 1 is removed, and the interior is filled with a liquid for purifying the air in the space containing a predetermined amount of perfume. This liquid may be prepared by using known liquids as they are or by adding necessary fragrances, disinfectants, etc. as appropriate.

In this state, jet air of a predetermined pressure is introduced from the air pressure source (not shown) from the air discharge pipe 5, thereby causing an upward air flow near the upper end of the suction pipe 4, and causing a flow of air inside the suction pipe 4. The filling liquid is sucked up and the sucked liquid is diffused from the upper end port.

The liquid from the suction tube is diffused and included in the gas flowing upward near the upper end of the suction tube. While flowing upward, it passes through the first and second passage restricting parts 7 and 8 on the way, and is discharged to the outside from the opening at the top.

As a result of the above, the gas containing the fragrance is continuously and constantly supplied to the outside, and the power for this is sufficient with an extremely small pump that circulates the jet air. This has the effect of keeping the air in the space in good condition.

(Effects of the invention) As mentioned above, the feature of the space air purifying device of the present invention is that it uses a simple mechanical device to continuously and adequately purify air without requiring frequent manual work. It has the function of discharging and supplying a large amount of fragrance, etc. into a space, and its practical effects are extremely large.
