[0036] Please refer to Figures 1 to 4. Figures 1 and 3 are schematic diagrams of the structure of the toilet 10 at different angles in some embodiments, Figure 2 is a schematic diagram of the structure of the toilet 10 installed on one side of the wall 30, and Figure 4 is a schematic diagram of the structure of the toilet 10 when the liquid adding mechanism 20 is in the first state in some embodiments. The toilet 10 provided in the present application has a foam generating device, which may include a liquid adding mechanism 20, a bubble mechanism, etc. The liquid adding mechanism 20 stores a foaming agent, and the foaming agent can be added to the liquid adding mechanism 20 during the use of the toilet 10. The foaming agent stored in the liquid adding mechanism 20 can enter the bubble mechanism to generate foam and flow into the toilet bowl 114 of the smart toilet 10, forming a foam shield at the bottom of the toilet bowl 114 to achieve a splash-proof function, or lubricating the side wall of the toilet bowl 114 to prevent dirt from sticking to the side wall. The foam generating device can also be provided with an air pump to ventilate the bubble mechanism so that the foaming agent is mixed with gas and water to generate foam. It should be noted that the present application mainly designs the liquid adding mechanism 20 of the foam generating device, and the arrangement of other mechanisms of the foam generating device is not limited to the description of the present application, and the liquid adding mechanism 20 can be used in any applicable foam generating device.

[0037] In some embodiments, the toilet 10 further includes a toilet seat 11, which includes but is not limited to being made of ceramic material, and is provided with a toilet bowl 114 and a receiving cavity 115, wherein the toilet bowl 114 is exposed for users to sit on, and the receiving cavity 115 is used to accommodate the siphon 12, the water tank 13 and other components in the toilet 10. The toilet seat 11 has a back surface 1111 for facing the wall 30, and the back surface 1111 is inclined to the wall 30 to form a liquid adding space 113. For example, as shown in FIG. 2 , the toilet seat 11 also has a lower surface 112 for contacting a carrier such as a floor, and after installation, the lower surface 112 is substantially horizontal, and the back surface 1111 is inclined to the lower surface 112. When the toilet 10 is installed next to a roughly vertically placed wall 30, the back side 1111 is inclined toward the side where the wall 30 is located in a direction parallel to the wall 30 and away from the lower surface 112, and a liquid adding space 113 is formed between the back side 1111 and the toilet 10. In a direction parallel to the wall 30 and pointing to the lower surface 112, the liquid adding space 113 gradually increases.

[0038] The liquid adding mechanism 20 is arranged in the receiving chamber 115, and the liquid adding mechanism 20 includes a liquid box 21 and a liquid adding tube 22. The liquid box 21 is provided with a liquid storage chamber 2122 for storing foaming agent, and the liquid adding tube 22 is provided with a liquid guide channel 2223 connected to the liquid storage chamber 2122. The liquid adding tube 22 is movably connected to the liquid box 21 to have a first state and a second state. As shown in FIG. 3 and FIG. 4, the back side 1111 is provided with an operation port 1112 connected to the receiving chamber 115, and at least a portion of the liquid adding mechanism 20 is opposite to the operation port 1112. When the liquid adding tube 22 moves to the first state relative to the liquid box 21, at least a portion of the liquid adding tube 22 protrudes from the operation port 1112 to the back side 1111 and forms a liquid adding port 2224 exposed to the liquid adding space 113, and the liquid adding port 2224 is connected to the liquid guide channel 2223. It can be understood that the first state is the state of the liquid adding mechanism 20 when the user can add foaming agent to the liquid adding mechanism 20. The user can use any suitable liquid adding tool such as a syringe, a hose, etc. to add the foaming agent to the liquid adding tube 22 through the liquid adding port 2224. The foaming agent flows from the liquid adding port 2224 into the liquid guiding channel 2223 in the liquid adding tube 22, and flows into the liquid storage cavity 2122 of the liquid box 21 through the liquid guiding channel 2223. After the liquid addition is completed, when the liquid adding tube 22 moves relative to the liquid box 21 to the second state, the liquid adding tube 22 is located in the toilet seat 11. In other words, the liquid adding tube 22 does not protrude from the back surface 1111, so that the liquid adding mechanism 20 is on the inner side of the back surface 1111.

[0039] The toilet 10 with the foam generating device can pull the liquid adding tube 22 out of the receiving cavity 115 to the liquid adding space 113 through the operating port 1112 during the liquid adding operation, so as to form a liquid adding port 2224 exposed to the liquid adding space 113, and then add liquid through the liquid adding port 2224. By designing the structure and position of the liquid adding mechanism 20, the liquid adding structure is located in the toilet seat 11 in the second state, i.e., in the non-liquid adding state, and is arranged corresponding to the operating port 1112 on the back side 1111 of the toilet seat 11. The liquid adding structure will not be exposed on the upper surface or cover plate of the toilet seat 11, which can improve the appearance integrity of the toilet 10, and will not occupy the space outside the toilet 10, which is conducive to compressing the size of the toilet 10. Furthermore, since the receiving chamber 115 of the toilet 10 near the operating port 1112 usually has extra space, the extra space in the receiving chamber 115 is used to accommodate the liquid adding mechanism 20, which is conducive to improving the space utilization efficiency of the toilet 10, compressing the volume of the toilet 10, and not easily affecting the spatial layout of the toilet 10, thereby reducing the difficulty of designing and preparing the toilet 10. At the same time, liquid is added by using the space formed by the back side 1111 of the toilet 10 tilted against the wall 30, which not only facilitates the cleaning between the toilet 10 and the wall 30, but also makes the operation of adding liquid more convenient, which is also conducive to improving the space utilization efficiency of the toilet 10.

[0040] In some embodiments, the liquid adding tube 22 is retractably connected to the liquid box 21, and when the toilet 10 is installed on one side of the wall 30, the withdrawal direction of the liquid adding tube 22 relative to the liquid box 21 points to the wall 30, for example, the withdrawal direction of the liquid adding tube 22 is horizontal, and the withdrawal stroke of the liquid adding tube 22 relative to the liquid box 21 is greater than the distance from the liquid box 21 to the back 1111. Such a configuration can ensure that the liquid adding tube 22 can be pulled to a part located in the liquid adding space 113 for easy liquid addition, and at the same time, it is beneficial to reduce the length of the pulling path of the liquid adding tube 22 and compress the overall occupied space of the liquid adding mechanism 20.

[0041] As shown in combination with Figures 4, 5 and 6, in some embodiments, the liquid box 21 includes a cover body 211 and a shell 212 connected to each other, and a liquid storage cavity 2122 is formed in the shell 212. For example, the shell 212 is a hollow structure and is open to the cover body 211, and the hollow space in the shell 212 is the liquid storage cavity 2122. The cover body 211 is provided with an inlet and outlet 2111 and a guide rail. The guide rail can be provided in the cover body 211 and on the surface of the cover body 211 facing the shell 212. The liquid adding tube 22 passes through the inlet and outlet 2111 and is slidably provided on the guide rail.

[0042] In some embodiments, the liquid adding tube 22 includes a tube body 222 and a limiting portion 221. The tube body 222 is slidably arranged on the guide rail and can enter and exit the cover body 211 from the inlet and outlet 2111. The limiting portion 221 is connected to the end of the tube body 222 and is located outside the cover body 211. The radial dimension of the limiting portion 221 is greater than the radial dimension of the inlet and outlet 2111. In the second state, the limiting portion 221 abuts against the cover body 211 and blocks the inlet and outlet 2111. The limiting portion 221 can limit the moving path of the tube body 222 on the guide rail, and in the second state, the limiting portion 221 can block the inlet and outlet 2111 to prevent dust or liquid in the receiving chamber 115 from entering the liquid storage chamber 2122 through the inlet and outlet 2111 and affecting the quality of the foaming agent.

[0043] In some embodiments, one end of the tube body 222 away from the limiting portion 221 is open to communicate with the liquid storage chamber 2122, and both ends of the tube body 222 away from each other can be open, one end of which is connected to the limiting portion 221 so that the opening is blocked by the limiting portion 221, and the opening of the other end communicates with the liquid storage chamber 2122. The tube body 222 includes a bottom plate 2221 and two side plates 2222, and the two side plates 2222 are respectively connected to the two sides of the floor and arranged oppositely. It can be understood that the bottom plate 2221 and the two side plates 2222 are surrounded to form a liquid guide channel 2223, and the opening at one end of the tube body 222 connects the liquid guide channel 2223 with the liquid storage chamber 2122. The side of the tube body 222 facing away from the housing 212 is open, and when the tube body 222 slides along the guide rail and partially slides out of the cover body 211 to the first state, the open part is exposed to form a liquid filling port 2224. The user can add foaming agent between the bottom plate 2221 and the two side plates 2222 through the opening of the tube body 222, i.e., the liquid filling port 2224. The foaming agent flows in the liquid guiding channel 2223 to the opening at one end of the tube body 222 away from the limiting portion 221, and flows down from the opening to the liquid storage chamber 2122 of the shell 212. In some embodiments, the cover 211 is hollow and open toward the shell 212, and the length of the tube body 222 is less than the length of the cover 211. Therefore, when the tube body 222 enters the cover 211 to switch to the second state, due to the limiting effect of the limiting portion 221, the opening of the tube body 222 away from the limiting portion 221 will not abut the cover 211, so that the foaming agent in the liquid guiding channel 2223 can still flow smoothly through the opening into the liquid storage chamber 2122 in the second state, and is not easily left in the liquid guiding channel 2223 and cannot be used.

[0044] Of course, the liquid filling port 2224 can also be formed in other ways. For example, the tube body 222 can also include a top plate (not shown) opposite to the bottom plate 2221, the top plate is connected to the two side plates 2222, and the top plate, the bottom plate 2221 and the two side plates 2222 jointly form a liquid guide channel 2223. An opening is set at a position of the top plate close to the limit portion 221. When the tube body 222 extends out of the cover body 211 to the first state, the opening of the top plate is exposed to the liquid filling space 113 to form the liquid filling port 2224. The specific arrangement of the liquid filling tube 22 and the liquid box 21 is not limited to the description of this application, as long as the liquid filling tube 22 can be switched between the first state and the second state relative to the liquid box 21, and can add foaming agent to the liquid storage chamber 2122 in the first state.

[0045] In some embodiments, the liquid adding tube 22 further includes a push-pull structure 223, which is connected to the side of the limiting portion 221 facing away from the cover body 211. In the second state, the push-pull structure 223 is located outside the cover body 211, and the user can pull the push-pull structure 223 to drive the liquid adding tube 22 to move relative to the liquid box 21 to switch to the first state. The push-pull structure 223 includes but is not limited to any suitable force-bearing structure such as a pull ring and an L-shaped rod. Further, in some embodiments, the toilet seat 11 has a seat wall 111 for being opposite to the wall 30. The seat wall 111 can be understood as the side wall of the toilet seat 11 facing the wall 30. The surface of the seat wall 111 facing away from the receiving cavity 115 is the back side 1111 of the toilet seat 11, and the operation port 1112 runs through the seat wall 111. In the second state, the push-pull structure 223 is located on the side of the back surface 1111 facing the receiving cavity 115, that is, located on the inner side of the back surface 1111, and at least partially located in the operation port 1112, for example, the end of the push-pull structure 223 extends into the operation port 1112 and faces the seat wall 111. Therefore, in the second state, the push-pull structure 223 will not extend out of the back surface 1111, and with the design that the back surface 1111 faces the wall 30, the operation port 1112 and the push-pull structure 223 will not affect the appearance integrity of the toilet 10. At the same time, the push-pull structure 223 is close to the back surface 1111, and the user can easily pull the push-pull structure 223 from the operation port 1112 to drive the liquid adding tube 22 to switch to the second state, which is more convenient to use.

[0046] In some embodiments, the liquid adding mechanism 20 further includes a first pipe 24, a second pipe 25 and a driving element 26. The first pipe 24 is connected to the liquid storage chamber 2122 of the shell 212 and the water inlet of the driving element 26. For example, the side of the shell 212 facing away from the cover body 211 is provided with an interface connected to the liquid storage chamber 2122 for the first pipe 24 to dock. One end of the second pipe 25 is connected to the water outlet of the driving element 26. The driving element 26 is used to drive the fluid in the liquid storage chamber 2122 to flow into the first pipe 24 and the second pipe 25 in sequence and then output from the second pipe 25. The end of the second pipe 25 away from the driving element 26 can be docked with the bubble mechanism, or can be connected with any other applicable elements, which can be specifically set according to the design of the foam generating device. The driving element 26 includes but is not limited to any applicable water pump such as a peristaltic pump. The use of a peristaltic pump can improve the purity of the foaming agent during the transportation process.

[0047] In some embodiments, the housing 212 includes a main body 2121 and a mounting portion 2124, the mounting portion 2124 is connected to the side of the main body 2121 facing away from the operation port 1112, the liquid storage chamber 2122 is provided in the main body 2121, and the driving element 26 is fixedly provided on the mounting portion 2124. In this way, the driving element 26 can be integrated with the liquid box 21, shortening the conveying path between the liquid storage chamber 2122 and the driving element 26, which is beneficial to the overall size and structural stability of the compression liquid adding mechanism 20. At the same time, the driving element 26 will not be exposed to the operation port 1112, and it is not easy to affect the appearance integrity of the toilet 10. The liquid box 21 can also provide effective protection for the driving element 26. In addition, the driving element 26 can also adapt to the spatial layout of the toilet 10, and is closer to components such as the bubble mechanism, thereby improving the space utilization efficiency in the toilet 10.

[0048] As shown in combination with FIG. 3 , FIG. 7 and FIG. 8 , in some embodiments, the toilet 10 further includes a mounting frame 14 and a water tank 13. The mounting frame 14 is disposed on the toilet seat 11 and is spaced apart from the toilet bowl 114. The mounting frame 14 may be a bearing structure for mounting components such as a water pump and a circuit board in the toilet 10. The toilet seat 11 is hollow and open. The mounting frame 14 may be disposed at the open portion of the toilet seat 11 and is surrounded by the toilet seat 11 to form a receiving cavity 115. The water tank 13 is disposed in the receiving cavity 115 and is connected to the bottom of the mounting frame 14. The liquid adding mechanism 20 is disposed on the side of the water tank 13 facing away from the mounting frame 14. The water tank 13 is used to contain the cleaning water of the toilet 10. The water in the bubble mechanism may also come from the water tank 13. It is understandable that there is usually vacant space at the bottom of the water tank 13, that is, the side of the water tank 13 facing away from the mounting frame 14. By setting a liquid adding mechanism 20 at the bottom of the water tank 13, it is possible to improve the space utilization efficiency of the toilet 10 and provide an effective bearing function for the liquid adding mechanism 20.

[0049] Further, in some embodiments, the water tank 13 has a bottom surface 131 facing away from the mounting frame 14, and a clearance groove 1311 is provided on the bottom surface 131. The siphon 12 of the toilet 10 passes through the water tank 13 and is partially located in the clearance groove 1311, which is conducive to improving the space utilization efficiency of the toilet 10 and allowing the siphon 12 and the water tank 13 to support each other to improve the structural stability of the toilet 10. In some embodiments, the clearance groove 1311 is provided in the middle of the bottom surface 131 of the water tank 13, and the clearance groove 1311 divides the bottom surface 131 into two installation positions 1312, and the liquid adding mechanism 20 is fixedly provided at one of the installation positions 1312. In this way, the liquid adding mechanism 20 is not easy to interfere with other components such as the siphon 12 in the toilet 10, which is conducive to improving the space utilization efficiency and structural reliability of the toilet 10.

[0050] In some embodiments, the liquid box 21 is suspended in the receiving cavity 115, and a liquid discharge port 2123 connected to the liquid storage cavity 2122 is provided on the side of the liquid box 21 facing away from the water tank 13. The liquid adding mechanism 20 also includes a cover 23, which is connected to the liquid discharge port 2123 of the liquid box 21 by any suitable detachable connection method such as snap, threaded connection, interference fit, etc. and blocks the liquid discharge port 2123. When the liquid adding mechanism 20 or other components fail, the cover 23 can be removed, and the foaming agent in the liquid storage cavity 2122 can be discharged through the liquid discharge port 2123 for easy detection or maintenance. At the same time, the space where the liquid box 21 is located is usually not easy to interfere with other components. The suspended space at the bottom of the liquid box 21 is usually an idle space in the toilet 10. Using this space for drainage can conveniently recover the discharged foaming agent, and it is not easy to interfere with other components, which effectively improves the space utilization efficiency of the toilet 10.

[0051] In some embodiments, the toilet 10 may further include components such as a cover plate and a seat ring that are rotatably connected to the toilet seat 11. The seat ring may rotate relative to the toilet seat 11 to cover the toilet bowl 114 for the user to sit on, and the cover plate may rotate relative to the toilet seat 11 to cover the seat ring to prevent odor leakage. The toilet 10 may also include any other applicable components to enrich the functions of the toilet 10. The above-mentioned components may also be replaced by any other applicable components to achieve corresponding effects, which will not be described in detail in this application.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
