Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0032] Combination Figures 1 to 8 This embodiment provides a seat ring sterilization and disinfection structure, including a cover plate 1, a seat ring 2, and a disinfection device 3. The cover plate 1 is equipped with an inner sealing element 11 for sealing with the inner hole of the seat ring 2 and an outer sealing element 12 for sealing with the outer periphery of the seat ring 2. The seat ring 2 is hinged to the cover plate 1. When the seat ring 2 is sealed with the inner and outer sealing elements, a sealed space is formed between the seat ring 2 and the cover plate 1. The disinfection device 3 is used to disinfect the seat ring 2 within the sealed space.

[0033] It should be noted that in this embodiment, by providing an inner sealing element 11 and an outer sealing element 12 on the cover plate 1 to seal the seat ring 2, a sealed space is formed for the disinfection device 3 to disinfect the seat ring 2, ensuring the hygiene of the seat ring 2, avoiding cross-infection of bacteria, and allowing users to use the toilet with peace of mind. Furthermore, the inner and outer sealing rings allow the seat ring 2 to be disinfected whether it is raised or lowered. Users can lift the seat ring 2 for disinfection when not in use, thereby improving the disinfection efficiency of the seat ring 2 and reducing waiting time.

[0034] In a preferred embodiment, the inner sealing element 11 includes a bracket 111 fixedly connected to the cover plate 1 and a retaining ring 112 mounted or formed on the side of the bracket 111 away from the cover plate 1. The sidewall of the bracket 111 is similar in shape to the inner hole of the seat ring 2, and the outer circumferential dimension of the retaining ring 112 is larger than the size of the inner hole of the seat ring 2. Specifically, a screw post is provided on the side of the bracket 111 near the cover plate 1, and the bracket 111 and the cover plate 1 are fixed by screws. The retaining ring 112 is made of soft rubber. When the seat ring 2 is fitted into the bracket 111, the retaining ring 112 can elastically deform and return to its original shape after the seat ring 2 is fitted into the bracket 111, so as to limit the seat ring 2. When disinfection is completed or the seat ring 2 needs to be used, force can be applied to remove the seat ring 2 from the bracket 111. The retaining ring 112 ensures the reliability of the seal and also serves as a limiter.

[0035] Furthermore, the outer sealing element 12 is provided along the periphery of the cover plate 1 facing the seat ring 2, and an elastic limiting part 121 is provided on the channel for the seat ring 2 to enter. The inner circumferential dimension of the elastic limiting part 121 is smaller than the outer circumferential dimension of the seat ring 2, so that the seat ring 2 is confined within the sealed space. The shape of the elastic limiting part 121 is similar to the outer circumferential shape of the seat ring 2, so that when the seat ring 2 is fitted into the bracket 111, its outer circumference compresses the elastic limiting part 121, and after being fitted into the bracket 111, the elastic limiting part 121 returns to its original shape, further ensuring the sealing performance of the sealed space. Simultaneously, it ensures that the seat ring 2 will not detach from the bracket 111 when not subjected to external force, ensuring that the user is not accidentally injured during the disinfection process. The material of the elastic limiting part 121 is preferably soft rubber. The limiting ring and the elastic limiting part 121 can be formed by secondary overmolding, but are not limited to this method and are not specifically restricted.

[0036] Based on the above embodiments, in an optional embodiment of this utility model, the cover plate 1 includes an upper cover and a lower cover 13, forming an assembly space between the upper cover and the lower cover 13 for accommodating a disinfection device 3. The disinfection device 3 includes one or more of a spraying mechanism 31, a drying mechanism 32, and an ultraviolet disinfection mechanism 33. The upper cover is a decorative cover. In one embodiment, the lower cover 13 is provided with multiple spray holes. The spraying mechanism 31 includes an instant heater 311, a nozzle 312, and a spray pipe 313. The water inlet end of the spray pipe 313 is connected to the instant heater 311, and the water outlet end of the spray pipe 313 is connected to the nozzle 312. The nozzle 312 is fixed inside the spray holes. When the instant heater 311 is turned on, high-temperature water flows from the spray pipe 313 to the nozzle 312 and is sprayed from the nozzle 312 onto the surface of the seat ring 2, thereby achieving high-temperature disinfection of the surface of the seat ring 2 and ensuring the hygiene of the seat ring 2. Preferably, the inlet of the instantaneous heater 311 is connected to the outlet of the storage water heater 314. For example, if the storage temperature in the storage water heater 314 is set to 60°C, the instantaneous heater 311 only needs to heat the 60°C water to boiling. This reduces the waiting time for heating and avoids excessive instantaneous power consumption by the instantaneous heater 311, which could damage the heater. It should be noted that the internal structure and working principle of the instantaneous heater 311 and the storage water heater 314 are existing technologies and will not be described in detail here.

[0037] In another embodiment, the lower cover 13 is provided with an air duct 14 for communicating with the sealed space, and the drying mechanism 32 includes a hot air blower 321, the air outlet of which faces the air duct 14. Hot air is output to sterilize and disinfect the surface of the seat ring 2. Preferably, the drying mechanism 32 and the spraying mechanism 31 are simultaneously arranged on the cover plate 1. After the spraying mechanism 31 sprays high-temperature water, the surface of the seat ring 2 is dried for user convenience.

[0038] In other embodiments, the lower cover 13 is provided with multiple mounting holes 15, and the ultraviolet disinfection mechanism 33 includes ultraviolet lamp beads 331 configured one-to-one with each mounting hole 15. The ultraviolet disinfection mechanism 33 can be provided separately or configured in the cover plate 1 simultaneously with the other two mechanisms, so that the seat ring 2 can be disinfected multiple times to ensure thorough disinfection.

[0039] In another embodiment, the bottom of the seat ring 2 is provided with a plurality of exhaust holes 21, each exhaust hole 21 being configured to communicate with an exhaust channel 22 equipped with an exhaust fan 23. For example, the seat ring 2 has an inner cavity communicating with the exhaust channel 22, each exhaust hole 21 communicating with the inner cavity, and the air outlet of the exhaust channel 22 communicating with the sewage pipe, so that when the user uses the toilet, they can turn on the exhaust fan 23 to remove the odor (or aerosol) from the toilet, thereby preventing the odor from spreading and affecting the air in the bathroom.

[0040] This utility model also provides a smart toilet, including a toilet seat 4 and a seat ring sterilization and disinfection structure as described in any of the above embodiments, disposed on the toilet seat 4. The cover plate 1 and the seat ring 2 are hinged on the toilet seat 4. The user can achieve a seal between the seat ring 2 and the inner and outer sealing elements by pressing down the cover plate 1, or by lifting the seat ring 2 and pressing it into the two sealing elements to achieve a seal. The operation is flexible and convenient for the user.

[0041] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
