Description

Technical Field

[0001] This invention belongs to the technical field of intelligent toilets and their supporting devices, specifically relating to a liquid filling device and an intelligent toilet. Background Technology

[0002] As people's demands for living standards increase, smart toilets with foam functions have appeared on the market. The foam layer generated by the foaming device covers the water surface of the toilet, which can play a good role in preventing splashing, blocking odors, moisturizing the wall, and sterilizing.

[0003] Currently, most toilets are equipped with a foam generating device, which includes a foaming box and a liquid filling device. Liquid from the liquid filling box flows into the foaming box, where it generates foam. Existing liquid filling devices typically extend the filling box by pulling or pressing. Both methods require gaps or recesses between the filling box and the outer cover or base for easy pulling, which is unsightly. Furthermore, there is no anti-backflow mechanism for repairing the inverted filling box support, or a rubber stopper is manually inserted at the filling port, which is also unsightly. These issues require further improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a liquid filling device with anti-backflow function and its intelligent toilet.

[0005] The embodiments of the present invention adopt the following technical solutions:

[0006] A liquid filling device for a smart toilet includes a liquid filling box and a liquid filling box support. The liquid filling box is movably disposed in the liquid filling box support. A movable cavity for moving the liquid filling box is formed inside the liquid filling box support. The liquid filling box is provided with a liquid outlet and a liquid filling port. It also includes an anti-backflow component disposed between the outer periphery of the liquid filling box and the inner wall of the movable cavity. The anti-backflow component includes a sealing ring sleeved on the outer periphery of the liquid filling box and abutting against the inner wall of the movable cavity.

[0007] Furthermore, the anti-reverse liquid assembly also includes an installation groove extending inward from the outer periphery of the liquid filling box, and the sealing ring includes a main body segment fitted in the installation groove and a sealing contact segment extending outward from the outer periphery of the main body segment and abutting against the inner wall of the moving cavity.

[0008] Furthermore, it also includes a sealing assembly disposed on the inner wall of the moving cavity opposite to the liquid outlet. When the liquid filling box is moved to the storage position, the sealing assembly can seal the liquid outlet.

[0009] Furthermore, the sealing assembly includes a sealing gasket disposed on the inner wall of the movable cavity that can be embedded in the liquid outlet.

[0010] Furthermore, the sealing assembly also includes a mounting base disposed on the inner wall of the movable cavity opposite to the liquid outlet for mounting the sealing gasket, and mounting screws for fixing the sealing gasket to the mounting base.

[0011] Furthermore, it also includes a motor and a transmission assembly. The motor is connected to the liquid filling box via the transmission assembly to drive the liquid filling box to move to the liquid filling position or the storage position.

[0012] Furthermore, the transmission assembly includes a transmission gear connected to the motor and a transmission rack disposed on the liquid filling box and meshing with the transmission gear, the transmission rack extending along the movement direction of the liquid filling box.

[0013] Furthermore, a partition plate is provided in the moving cavity. One end of the partition plate is connected to the inner wall of the moving cavity, and the other end extends outward along the moving direction of the liquid filling box, so as to divide the moving cavity into a first chamber for the liquid filling box to move and a second chamber for the transmission rack to move. The sealing ring abuts against the inner wall of the first chamber, and a guide area for the partition plate to be embedded is formed between the liquid filling box and the transmission rack.

[0014] Furthermore, it also includes a liquid outlet pipe located at the bottom of the liquid filling box bracket and communicating with the moving cavity.

[0015] A smart toilet includes a toilet body, characterized in that it further includes a liquid filling device as described in any of the above claims disposed in the toilet body.

[0016] As can be seen from the above description of the embodiments of the present invention, compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: By defining the structure of the liquid adding device, a sealing ring is added inside to seal the gap between the liquid adding box and the inner wall of the moving cavity, and a sealing gasket is set to seal the liquid outlet of the liquid adding box when it is in the storage position. When the liquid adding box is in the liquid adding position, the sealing ring ensures that the overflowing foaming liquid will not flow outward. When the liquid adding device is inverted for maintenance, the sealing ring, together with the sealing gasket, can ensure that the foaming liquid in the liquid outlet pipe will not flow outward, affecting the maintenance of the liquid adding device, and greatly improving the convenience of maintenance of the liquid adding device. At the same time, the sealing ring and the sealing gasket are both set inside the device, which increases the convenience of installation and the overall aesthetics of the machine.

Detailed Implementation

[0024] The present invention will be further described below through specific embodiments.

[0025] A smart toilet includes a toilet body, a foam box disposed in the toilet body, and a filling device with anti-backflow function for adding liquid to the foam box.

[0026] Reference Figures 1 to 6 As shown, the liquid adding device includes a liquid adding box 1, a liquid adding box support 2, an anti-backflow component 3, a sealing component 4, a liquid outlet pipe 5, a motor 6, and a transmission component 7.

[0027] The liquid filling box 1 is movably disposed in the liquid filling box bracket 2 and moves back and forth between the storage position and the liquid filling position. It includes the liquid filling box body 11, the liquid filling chamber 12 disposed in the liquid filling box body 11, the liquid outlet 13 communicating with the front end of the liquid filling chamber 12, and the liquid filling port 14 for adding liquid into the liquid filling chamber 12. The liquid filling position is the position where the liquid filling box 1 moves outward to the position where the liquid filling port 14 is exposed and foaming liquid can be added. The storage position is the position where the liquid filling box 1 moves back into place after the foaming liquid is added. When in the storage position, the liquid filling box 1 is usually referred to as a hidden or partially hidden state.

[0028] The liquid filling box support 2 has a movable cavity 21 for the liquid filling box 1 to move back and forth.

[0029] The liquid outlet pipe 5 is located at the bottom of the liquid filling box bracket 2 and communicates with the moving cavity 21. The liquid outlet pipe 5 is L-shaped and located at the bottom of the liquid filling box bracket 2.

[0030] The anti-spillage component 3 is disposed between the outer periphery of the liquid filling box body 11 and the inner wall of the moving cavity 21. It includes a sealing ring 31 that is fitted around the outer periphery of the liquid filling box body 11 and abuts against the inner wall of the moving cavity 21, and a mounting groove 32 that extends inward from the outer periphery of the liquid filling box body 11 for installing the sealing ring 31. The sealing ring 31 includes a main body section 33 fitted in the mounting groove 32 and a sealing contact section 34 that extends outward from the outer periphery of the main body section 33 and abuts against the inner wall of the moving cavity 21. By providing a sealing ring 31 that abuts against the inner wall of the moving cavity 21 on the outer periphery of the liquid filling box body 11, the sealing between the outer periphery of the liquid filling box 1 and the inner wall of the moving cavity 21 can be maintained when the liquid filling box 1 is in the liquid filling position, preventing the foaming liquid from flowing out through the gap between the two and increasing the difficulty of subsequent processing. Moreover, the sealing ring 31 is located inside the device, which increases the convenience of installation and the aesthetics of the whole machine.

[0031] The sealing component 4 is disposed on the inner wall of the moving cavity 21 opposite to the liquid outlet 14. When the liquid filling box 1 moves to the storage position, the sealing component 4 can be embedded in the liquid outlet 13 to seal the liquid outlet 13. Specifically, the sealing component 4 includes a sealing gasket 41 disposed on the inner wall of the moving cavity 21 that can be embedded in the liquid outlet 13, a mounting base 42 disposed on the inner wall of the moving cavity 21 opposite to the liquid outlet 13 for mounting the sealing gasket 41, and mounting screws 43 for fixing the sealing gasket 41 to the mounting base 42. The sealing gasket 41 has mounting holes 411 formed on it for the mounting base 42 to be embedded in. By setting the sealing gasket 41 that can seal the liquid outlet 13 on the inner wall of the moving cavity 21 opposite to the liquid filling port 14, when the liquid filling device is inverted for maintenance, the sealing ring 31 cooperates with the sealing gasket 41 to prevent the foaming liquid in the liquid outlet pipe 5 from flowing back out of the liquid filling box 1, thereby improving the convenience of maintenance of the liquid filling device.

[0032] The motor 6 is connected to the liquid filling box 1 via the transmission component 7 to drive the liquid filling box 1 to move to the liquid filling position or the storage position. Specifically, the liquid filling box bracket 2 is provided with a waterproof motor sleeve 25 for mounting the motor 6.

[0033] The transmission assembly 7 includes a transmission gear 71 connected to the motor 6 and a transmission rack 72 disposed on the liquid filling box 2 and meshing with the transmission gear 71. The transmission rack 72 is disposed on one side of the liquid filling box body 11 and extends along the moving direction of the liquid filling box 1. Specifically, the transmission rack 72 is integrally formed with the liquid filling box body 11. When the motor 6 is working, it drives the transmission gear 71 to rotate, and the transmission gear 71 meshes with the transmission rack 72, so that the liquid filling box 1 can move back and forth between the storage position and the liquid filling position. Through the cooperation of the motor 6 and the transmission assembly 7, the electric motor 6 drives the liquid filling box 1 to retract, which is convenient and quick, and can also greatly reduce the gap between the liquid filling box 1 and the external parts, making the liquid filling device more aesthetically pleasing.

[0034] Correspondingly, a partition plate 22 is provided in the moving cavity 21. One end of the partition plate 22 is connected to the inner wall of the moving cavity 21, and the other end extends outward along the moving direction of the liquid filling box 1, so as to divide the moving cavity 21 into a first chamber 23 for the liquid filling box 1 to move and a second chamber 24 for the transmission rack 72 to move. The sealing ring 31 is sleeved on the outer periphery of the liquid filling box body 11 and abuts against the inner wall of the first chamber 23. Specifically, a guide area 26 is formed between the liquid filling box 2 and the transmission rack 72 for the partition plate 22 to be embedded. When the liquid filling box 2 retracts inward or extends outward, it will change the embedding depth of the partition plate 22 in the guide area 26, which plays a guiding role in the extension or retraction of the liquid filling box 2 and ensures the stability of the extension or retraction process of the liquid filling box 2.

[0035] This application defines the structure of the liquid filling device by adding a sealing ring 31 inside to seal the gap between the liquid filling box 1 and the inner wall of the moving cavity 21, and setting a sealing gasket 41 to seal the liquid outlet 13 of the liquid filling box 1 when it is in the storage position. When the liquid filling box 1 is in the liquid filling position, the sealing ring 31 prevents the overflowing foaming liquid from flowing outward. When the liquid filling device is inverted for maintenance, the sealing ring 31, together with the sealing gasket 41, ensures that the foaming liquid in the liquid outlet pipe 5 does not flow outward, thus affecting the maintenance of the liquid filling device and greatly improving the convenience of maintenance. At the same time, the sealing ring 31 and the sealing gasket 41 are both set inside the device, which increases the convenience of installation and the overall aesthetics of the machine.

[0036] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
