Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, and in particular to a water deodorizing device with large installation tolerance and an intelligent toilet. Background Art

[0002] The existing smart toilet has a water deodorization device, which uses water and odor to mix to dissolve components such as ammonia or hydrogen sulfide in the odor to achieve the purpose of deodorization. When deodorizing, the electronic cover needs to spray water on the fence on the deodorization chamber to form a water film, and some residual water will adhere to the deodorization chamber. During the process of removing and replacing the cover, the cover may be tilted or inverted, and the accumulated water in the water deodorization device may flow back into the fan and corrode the fan, affecting the function. At the same time, existing technologies such as patent CN202223281846.6, a smart toilet seat and a smart toilet with a deodorizing device, can prevent residual water in the deodorizing chamber from flowing to the exhaust fan when the smart toilet seat is inverted, but the height of the valve stem of the control valve and the abutment plate is fixed, and thus the installation height of the control valve on the toilet cover is fixed. When the height of the mounting support surface changes due to differences in the toilet production process or the assembly of toilet accessories, the deodorizing air inlet will not open normally or the opening height will be insufficient, thereby affecting the normal operation of the deodorizing function.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] refer to Figures 1 to 5 As shown, a water deodorizing device with a large installation tolerance includes a deodorizing chamber 1 installed on a toilet cover, an air inlet 11 and an air outlet 15 are provided on the deodorizing chamber 1, the air inlet 11 is connected to a deodorizing fan 4, and an anti-backflow device 2 is provided at the position of the air inlet 11, the anti-backflow device 2 includes a reset rod 21, a reset spring 22, and an elastic member 23, and the elastic member 23 pushes the reset rod 21 to open the air inlet 11 after abutting against the installation support surface 3 on the toilet. Among them, other matching structures of the anti-backflow device 2 can refer to the control valve structure of the prior art, and can be designed after adaptive adjustment. This solution achieves matching with different cover installation heights by setting an anti-backflow structure of a reset spring 22 and an elastic member 23, and the deodorizing function can be normally opened after installation within a certain installation height range. Such a design has a large installation tolerance, good versatility, simple and practical structure, low cost, and can increase user experience and application range.

[0035] Based on the above technical solution, the reset rod 21 includes a sealing valve plate 211, which is arranged at one end of the reset rod 21 close to the air inlet 11 and connected to the reset rod 21. The sealing valve plate 211 can open or close the air inlet 11 under the drive of the reset rod 21, and then the sealing valve plate 211 can cooperate with the connection to the air inlet 11 to complete the sealing cooperation opening and closing.

[0036] Specifically, in a preferred embodiment, the elastic member 23 includes a push rod 231 and a push rod spring 232, the push rod 231 and the push rod spring 232 are arranged between the reset rod 21 and the mounting support surface 3, and the elastic force of the push rod spring 232 is greater than the elastic force of the reset spring 22; when the toilet cover is removed, that is, the push rod 231 is separated from the mounting support surface 3, the push rod spring 232 is in a non-compressed state, and the reset spring 22 is in a compressed state A, so that the sealing valve plate 211 closes the air inlet 11, and the anti-backflow function takes effect; when the toilet cover is installed, that is, the push rod 231 and the mounting support surface 3 are at the target installation height, the push rod 231 is subjected to force to make the push rod spring 232 in a compressed state, the reset spring 22 is in a compressed state, the elastic force of the reset spring 22 is greater than the elastic force of the push rod spring 232, and the reset rod 21 pushes the sealing valve plate 211 to open the air inlet 11, so that the air inlet 11 is opened for ventilation and deodorization.

[0037] More specifically, Figure 2 When the push rod 231 and the mounting support surface 3 are at the installation height H1, the push rod 231 is subjected to force so that the push rod spring 232 is in the compressed state 1, and the return spring 22 is in the compressed state B. The elastic force F1 of the push rod spring 232 is greater than the elastic force FB of the return spring 22. The return rod 21 pushes the sealing valve plate 211 to open the air inlet 11, and the deodorization function can work normally. Figure 3 When the top rod 231 and the mounting support surface 3 are at the installation height H2, the top rod 231 is subjected to force to make the top rod spring 232 in the compressed state 2, and the return spring 22 is in the compressed state B. Similarly, the elastic force F2 of the top rod spring 232 is greater than the elastic force FB of the return spring 22, and the return rod 21 pushes the sealing valve plate 211 to open the air inlet 11, and the deodorization function can still work normally. In this way, the anti-backflow device 2 can be applied to any installation height within the range of H1 to H2, and will not affect the normal use of the deodorization function.

[0038] In an optional embodiment, if Figure 4 The elastic member 23 is only a push rod spring 232, and the push rod spring 232 is arranged between the reset rod 21 and the mounting support surface 3. Such a design is understandable and can also achieve the same purpose as above.

[0039] In another preferred embodiment, Figure 5 The elastic member 23 may be a reset rod elastic part 233, which is preferably an elastic member extending downward from the reset rod 21 and is disposed between the reset rod 21 and the mounting support surface 3, which can also achieve the same purpose of the present application. Optionally, the reset rod elastic part 233 is integrally formed with the reset rod 21.

[0040] It can be understood that the mounting support surface 3 can optionally be a toilet accessory or a toilet main body.

[0041] For the purpose of better deodorization and backflow prevention, the deodorization chamber 1 is also provided with a water spray port 12 connected to the deodorization chamber 1. External water enters the deodorization chamber 1 through the water spray port 12 to deodorize the gas in the deodorization chamber; the deodorization chamber 1 is also provided with at least one fence, which is provided with a flow hole 16. External water flows into the deodorization chamber 1 from the water spray port 12 and drips on the fence, thereby being adsorbed on the flow hole 16 and forming a water film, which absorbs and purifies the odor and then discharges it from the deodorization chamber 1. The deodorization fan 4 connected and arranged near the air inlet 11 can blow the odor into the deodorization chamber 1. After the odor passes through the water film on the fence, the water film can absorb the odor substances and produce a chemical reaction, thereby producing a deodorization effect.

[0042] like Figure 1-5 As shown, the fence is preferably a first fence 13 and a second fence 14 set at an angle, the first fence 13 is located above the second fence 14, and the first fence 13 and the second fence 14 are set obliquely along the intersecting direction. On the one hand, the water flows from the flow hole 16 of the first fence 13 to drip on the second fence 14 to form a water film. On the other hand, the inclined setting of the fence facilitates the water flow to spread better on the fence, which is conducive to forming a stable water film. When the deodorizing fan 4 blows the odor into the deodorizing chamber 1, it is absorbed by the fence water film to complete the deodorization operation, wherein the odor can pass through the water film twice, which can achieve a better deodorization purpose. Of course, multiple groups of the above structures can be set, so as to better achieve the purposes of deodorization and backflow prevention.

[0043] Further, such as Figure 6 As shown, the deodorizing chamber 1 is further provided with a water accumulation area 17, which is specifically arranged below the first fence 13 and the second fence 14 along the intersecting direction to form a water seal with the inner wall of the deodorizing chamber to prevent odor from being directly discharged from the deodorizing chamber from the air outlet, wherein the water accumulation area 17 and the air outlet are staggered so that the residual water in the water film can be concentrated along the intersection of the inclined fences to flow into the water accumulation area 17 to avoid the air outlet 15, wherein the water accumulation area 17 can be optionally a water trough and have an overflow port 18, and the overflow port 18 is preferably connected to the air outlet 15, when the fence is used for too long, the flow hole 16 is blocked by impurities, and the water that cannot flow through the flow hole can overflow from the overflow port 18, which does not affect the normal use of the water deodorizing device.

[0044] In addition, if Figure 1-5 As shown, the arrows in the figure indicate the airflow path. Figure 6 Arrows indicate water flow paths.

[0045] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
