Description

Technical Field

[0001] This utility model relates to the field of sanitary ware accessories technology, specifically a toilet deodorizing device. Background Technology

[0002] Currently, toilet seats are widely used. Because toilet seats are used for human excretion and are in constant contact with excrement, they easily become contaminated with foul-smelling waste. The dirt and dampness inside the toilet, along with the odors in the air, create ideal conditions for bacterial growth and infection, easily generating aerosols and odors. These odors affect air quality and reduce the comfort of residents' daily lives. To address these problems, most methods involve using scented air fresheners to temporarily mask the odor or installing exhaust fans in the bathroom to reduce it. While these methods can reduce odor, the effect is not ideal, as the toilet odor will still permeate the bathroom for a period of time. Furthermore, commercially available deodorizing toilets typically use multiple small air holes in their air supply structure. This dispersed airflow cannot effectively seal off aerosols and odors, allowing them to leak into the bathroom, resulting in poor deodorization and a negative impact on the user experience. Therefore, providing a toilet deodorizing device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1As shown, a toilet deodorizing device includes an air supply assembly, an exhaust assembly, a power supply 1, and a protective shell 2. The air supply assembly includes an annular air supply pipe 3 and an exhaust fan 4. One end of the air supply pipe 3 is connected to the exhaust fan 4. One side of the air supply pipe 3 is open. An air supply guide structure 5 is provided on one side of the air supply pipe 3. The air supply guide structure 5 is integrally formed with the air supply pipe 3. The exhaust assembly includes an exhaust pipe 6 and an exhaust fan 7. One end of the exhaust pipe 6 is connected to the exhaust fan 7. The exhaust pipe 6 is located below the air supply pipe 3. The exhaust fan 7, the exhaust fan 4, and the power supply 1 are all installed inside the protective shell 2. The power supply 1 provides power to the exhaust fan 7 and the exhaust fan.

[0027] It should be noted that the air delivered by the annular air supply duct 3 forms an air curtain, which seals off the odor and prevents it from escaping. The exhaust duct 6 is used to remove the odor. The exhaust fan 7 (exhaust fan) and the air supply fan 4 (intake fan) in this embodiment are both existing technologies, so they will not be described in detail here.

[0028] It should be further explained that by setting one side of the air supply pipe 3 to be open and the air supply pipe 3 having an air supply guide structure on one side, it is beneficial for the air supplied by the air supply pipe 3 to form an air curtain. Compared with the previous method of opening multiple small holes on the air supply pipe 3, this utility model can achieve the sealing of aerosols and odors, prevent odors from leaking out, and has good use effect and strong practicality.

[0029] like Figure 4 As shown, the air supply guide structure 5 includes a windbreak part 8 and an air guide part 9 arranged sequentially from top to bottom. The windbreak part 8 is parallel, and the air guide part 9 is inclined downward.

[0030] like Figure 1 and Figure 2 As shown, an air outlet 10 is formed between the windbreak part 8 and the air guide part 9. The air outlet 10 is connected to the interior of the air supply pipe 3. The air outlet 10 is inclined downwards so that the air discharged from the air supply pipe 3 is sent out through the air outlet 10 to form an air curtain.

[0031] It should be noted that by tilting the air outlet 10 downwards, the air discharged from the annular air supply pipe 3 is sent out through the air outlet 10 to form an air curtain, which forms a convection with the exhaust pipe 6. This can effectively seal off aerosols and odors in the toilet, prevent aerosols and odors from spreading into the bathroom, prevent odor leakage, and has a good effect.

[0032] like Figure 3 As shown, the lower end of the exhaust pipe 6 is provided with a plurality of exhaust holes 11, which are spaced apart.

[0033] It should be noted that after the aerosols and odors in the toilet are blocked and sealed by the air curtain above, under the suction of the exhaust fan, the aerosols and odors are transported through the exhaust hole 11 to the exhaust pipe 6, and finally transported to the sewage pipe of the bathroom, and finally discharged outdoors, thus further ensuring the air quality in the bathroom.

[0034] like Figure 1 and Figure 2 As shown, the exhaust assembly also includes an exhaust backflow preventer 12, which is connected to the exhaust fan 7. The exhaust backflow preventer 12 in this embodiment can be installed in a position that can be adjusted according to the actual usage scenario.

[0035] It should be noted that the odor is delivered to the toilet's sewage pipe after passing through the exhaust backflow prevention device 12. The exhaust backflow prevention device 12 can prevent the gas in the sewage pipe from flowing back when it is not in operation.

[0036] It should be further explained that the exhaust backflow prevention device 12 in this embodiment can be a mechanical check valve structure, a filter media interception structure, or other common structures: the mechanical check valve structure adopts a mechanical baffle design similar to an exhaust check valve. When the exhaust fan 7 is working, the airflow pushes the valve disc to open; when the exhaust stops, the valve disc automatically closes under its own weight or spring action, effectively blocking the backflow of gas in the sewage pipe; the filter media interception structure can adopt activated carbon or photocatalytic filter boxes. Activated carbon or photocatalytic filter boxes have both deodorization and backflow prevention functions. Odors must be forced to pass through the porous adsorption layer to be discharged, and the reverse airflow will be blocked by the dense filter material.

[0037] like Figure 1 and Figure 2 As shown, it also includes a mounting pad 13, which is located inside the protective shell 2. The exhaust fan 7, the blower 4, and the power supply 1 are all mounted on the mounting pad 13.

[0038] It should be noted that the mounting pad 13 in this embodiment can be a shock-absorbing pad, made of highly elastic rubber material, which has both high elasticity and wear resistance. It absorbs vibration energy through elastic deformation, reduces the noise of the exhaust fan 7 and the air supply operation, and improves the comfort of the working environment.

[0039] like Figure 1 and Figure 2 As shown, it also includes a support base 14 and a connecting base 15. The lower end face of the support base 14 is connected to the upper end face of the air supply pipe 3, the upper end face of the connecting base 15 is connected to the air supply pipe 3, and the lower end face of the connecting base 15 is connected to the exhaust pipe 6. This utility model can be installed inside the seat plate or inside the bucket lid.

[0040] like Figure 1 and Figure 2As shown, the exhaust assembly also includes an exhaust connection pipe 16. One end of the exhaust connection pipe 16 is connected to the exhaust fan 7, and the other end of the exhaust connection pipe 16 extends outward through the exhaust anti-backflow device 12 and the protective shell 2 to connect with the sewage pipe of the bathroom.

[0041] It should be noted that, with the above structure, the exhaust fan 7 draws the gas through the exhaust pipe 6 into the exhaust connection pipe 16, and then through the exhaust connection pipe 16 and the exhaust anti-backflow device 12, the treated gas is directly delivered to the sewage pipe of the bathroom and finally discharged outdoors, further ensuring the air quality in the bathroom.

[0042] like Figure 2 As shown, the air supply assembly also includes an air supply connecting pipe 17, one end of which is connected to the blower 4, and the other end of which extends outward through the protective shell 2.

[0043] It should be noted that the other end of the air supply connection pipe 17 can be extended to the outside or the building ventilation system through an external pipe, and the introduction of fresh outside air helps to form an air curtain to block odors.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can readily implement the present utility model according to the accompanying drawings and the above description. However, any modifications, alterations, or equivalent changes made by those skilled in the art without departing from the scope of the present utility model's technical solution, based on the disclosed technical content, are all equivalent embodiments of the present utility model. Furthermore, any equivalent changes, alterations, or evolutions made to the above embodiments based on the essential technology of the present utility model still fall within the technical solution of the present utility model.
