[0002] A public toilet, abbreviated as a public lavatory, refers to a toilet jointly used by urban residents and floating population. Generally, public toilets are built in areas with dense human flow (such as stations, hospitals, cinemas, exhibition halls, office buildings, etc.).

[0003] However, the excrement in public toilets will generate odor gases that fill the public toilets, and the urea component in the excrement will produce pungent odors after chemical reactions. At present, the air purification in public toilets mainly adopts fan circulation air. Most fans are installed at the upper part of the toilet, and the fan is used to directly discharge the dirty air in the toilet. However, with this structure, since the fan is set at the top, the dirty air moves upward, and when people use the public toilet, the odor of the dirty air is serious, affecting comfort. At the same time, the directly discharged gas will still directly contact the surrounding environment, causing environmental pollution to the surrounding area. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a new type of public toilet to solve the problems existing in the prior art that the odor of the dirty air in public toilets is serious, affecting comfort, and directly discharging the dirty air causes pollution to the surrounding environment.

Detailed implementation manners [[ID=2!5]]

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Please refer to Figures 1 to 4 As shown, a new public toilet includes a main body 1, an air inlet space 12, an air outlet space 13, a purification component 2, a circulating air box 4, a fragrance box 6 and a feeding component 7. The main body 1 is a public toilet in the prior art. A main body door 11 is provided on the front side of the main body 1, and it has a flushing toilet inside, which will not be elaborated here. The air inlet space 12 is arranged at the top inside the main body 1 and is used to discharge purified air into the main body 1. The air outlet space 13 is arranged at the bottom inside the main body 1 and is used to discharge the foul air with odor in the main body 1. By arranging the air outlet space 13 at the bottom of the main body 1 and the air inlet space 12 at the top of the main body 1, the purified air flows from top to bottom, while the foul air with odor directly flows downward and flows out from the bottom of the main body 1, avoiding the foul air with odor floating into the upper space of the main body 1 and affecting the experience and comfort of users.

[0028] In this embodiment, a first partition 131 is fixedly installed at the lower part inside the main body 1. An air outlet space 13 is formed between the first partition 131 and the bottom surface of the main body 1. A plurality of through holes 1311 are evenly distributed on the first partition 131. The dirty air inside the main body 1 flows into the air outlet space 13 through the through holes 1311. A second partition 121 is fixedly installed at the upper part inside the main body 1. An air inlet space 12 is formed between the second partition 121 and the top surface of the main body 1. The purified air enters the inside of the main body 1 through the second partition 121. Preferably, the second partition 121 is a flow equalizing film. By setting the second partition 121 as a flow equalizing film, a uniform and vertically downward unidirectional air flow is generated for the purified air, thereby driving the smelly dirty air inside the main body 1 to flow directly downward, and at the same time preventing the air flow in the air inlet space 12 from directly blowing on the user, resulting in poor comfort.

[0029] The purification component 2 is fixedly installed on the outer side wall of the main body 1 and is used to purify the dirty air from the inside of the main body 1. In this embodiment, the purification component 2 is fixedly installed on the outer side wall of the main body 1. The input end of the purification component 2 is connected to the air outlet space 13 through a first air duct 3. A circulation air box 4 is arranged above the purification component 2 and is connected to the output end of the purification component 2. The output end of the circulation air box 4 is connected to the air inlet space 12 through a second air duct 5.

[0030] Specifically, a circulation fan (not shown in the figure) is arranged inside the circulation air box 4. During implementation, when the circulation fan is started, at this time, the dirty air inside the main body 1 sequentially passes through the air outlet space 13, the first air duct 3, the purification component 2, the circulation air box 4, and the second air duct 5 and then is discharged into the air inlet space 12, and then through the second partition 121 of the air inlet space 12, the purified air is discharged back into the inside of the main body 1 again, and this cycle is repeated.

[0031] Preferably, an exhaust net 14 is provided on the outer side wall of the main body 1 on one side of the air inlet space 12, and the permeability of the second partition 121 (flow equalizing film) is less than that of the through holes 1311 of the first partition 131. By doing so, when the circulation fan is started, part of the air is discharged through the exhaust net 14, and part of the air flows into the main body 1 through the first partition 131, so that a slight negative pressure is generated inside the main body 1, so as to better prevent the smelly dirty air from floating upward in the main body 1 and affecting the comfort of the user.

[0032] In this embodiment, in the air inlet space 12, a fragrance box 6 is connected and arranged below the second air duct 5. One side of the fragrance box 6 is connected and arranged with a feeding component 7. The feeding component 7 includes a horizontal pipe 71 and a vertical pipe 72. One end of the horizontal pipe 71 is connected and arranged on one side of the fragrance box 6. The horizontal height of the horizontal pipe 71 is located at the bottom of the fragrance box 6. The other end of the horizontal pipe 71 passes through the main body 1 and extends to the outside of the main body 1. The bottom end of the vertical pipe 72 is connected and arranged at the other end of the horizontal pipe 71. The horizontal height of the top end of the vertical pipe 72 is equal to the height of the top end of the fragrance box 6.

[0033] It should be noted that the fragrance box 6 stores a liquid fragrance agent. The staff can add the fragrance agent into the vertical pipe 72, so that the fragrance agent flows into the fragrance box 6. Since the horizontal height of the top end of the vertical pipe 72 is equal to the height of the top end of the fragrance box 6, through the principle of communicating vessels, the height of the liquid in the vertical pipe 72 can be observed, and then the filling condition of the fragrance agent in the fragrance box 6 can be judged. During implementation, the circulation fan conveys the purified air into the second air duct 5. During the air flow in the second air duct 5, the air can be mixed with the fragrance emitted from the fragrance box 6 and then discharged, and finally discharged into the main body 1 through the air inlet space 12. Preferably, the vertical pipe 72 is made of a transparent material to facilitate the staff to observe. Further, a cover body 73 is screwed at the top end of the vertical pipe 72.

[0034] In this embodiment, the purification component 2 includes a purification box 21. Inside the purification box 21, a spraying component 22, a dehumidifying component 23, a heating component 25 and an activated carbon filter screen 24 are sequentially arranged from bottom to top. Specifically, a liquid deodorant 221 is stored at the bottom of the purification box 21. The spraying component 22 includes a spraying pipe 222 fixedly arranged above the liquid deodorant 221 and a plurality of spray heads 223 arranged on the spraying pipe 222. The spraying pipe 222 is connected and communicated with the bottom of the purification box 21 through a pressure pump 224. The output end of the first air duct 3 is located between the liquid deodorant 221 and the spraying pipe 222.

[0035] During implementation, the dirty air in the main body 1 is discharged into the purification box 21 through the first air duct 3. At this time, the pressure pump 224 extracts the liquid deodorant 221 located at the bottom of the purification box 21 and pumps it into the spraying pipe 222, and then sprays it out from the spray heads 223, so as to purify the dirty air through the liquid deodorant 221 and remove the odor. It should be noted that the sprayed liquid deodorant 221 will fall back to the bottom of the purification box 21 again to achieve the effect of repeated use.

[0036] In this embodiment, the dehumidification component 23 is a corrugated plate, which is used to remove the moisture in the air processed by the spraying component 22. Specifically, the corrugated plate is a prior art. When the air passes through the gaps of the corrugated plate, turbulence and vortices are generated. These turbulence and vortices help to increase the contact opportunities between the droplets in the air and the wall surface of the corrugated plate, thereby achieving the dehumidification effect. By setting the corrugated plate for dehumidification, it is possible to avoid the influence of high-humidity air on the activated carbon filter screen 24, that is, the high-humidity air may reduce the service life of the activated carbon filter screen 24 described below. And the activated carbon filter screen 24 is used to further eliminate the odor in the air.

[0037] In this embodiment, the heating component 25 is a plurality of electric heating tubes. By setting the electric heating tubes, the temperature of the air can be increased, the density of the air can be reduced, and the water vapor can be kept in a gaseous state to better pass through the activated carbon filter screen 24. At the same time, by setting a plurality of electric heating tubes, the activated carbon filter screen 24 can be dried to further extend its service life.

[0038] When the specific implementation of the present utility model is carried out, the staff starts the circulation fan. At this time, the dirty air inside the main body 1 enters the air outlet space 13 from top to bottom, and then enters the purification box 21 through the first air duct 3. Then, the dirty air is filtered into clean air through the spraying component 22, the dehumidification component 23 and the activated carbon filter screen 24 in the purification box 21. The purified air is driven by the circulation fan into the second air duct 5. At this time, the air in the second air duct 5 is discharged after mixing the fragrance emitted from the fragrance box 6 during the flowing process, and finally is re-discharged into the main body 1 through the second partition 121 of the air inlet space 12.

[0039] The above description content is only a preferred embodiment of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
