[0050] The disclosed embodiment discloses a toilet. The toilet includes a toilet body and a foaming device, which is arranged on the toilet body. The foaming device produces foam that can cover the water cover to achieve the effects of splash prevention, odor isolation, sound insulation, softening yellow scale and antibacterial, which helps to maintain the cleanliness and hygiene of the toilet.

[0051] Please combine Figures 1 to 3 and Figures 5 to 8, the foaming device provided by the embodiment of the present disclosure is now described. The foaming device includes a main body 10 and a movable component 20. The main body 10 is provided with a liquid storage chamber 100, a liquid mixing chamber 200 and a mounting chamber 300. A liquid inlet hole 400 is connected between the liquid storage chamber 100 and the mounting chamber 300. The liquid inlet hole 400 is configured to guide the foaming liquid under the action of gravity from the liquid storage chamber 100 to the mounting chamber 300. The opening of the liquid inlet hole 400 enables the foaming liquid to automatically flow from the liquid storage chamber 100 into the mounting chamber 300 under the action of gravity.

[0052] A liquid adding hole 500 is connected between the liquid mixing chamber 200 and the installation chamber 300, and the liquid adding hole 500 is arranged to prevent the foaming liquid under the action of gravity from being guided from the installation chamber 300 to the liquid mixing chamber 200. The arrangement of the liquid adding hole 500 can prevent the foaming liquid from flowing from the installation chamber 300 to the liquid mixing chamber 200 under the action of gravity, and the foaming liquid can only be added to the liquid mixing chamber 200 from the installation chamber 300 under the action of external force.

[0053] The movable component 20 can be movably mounted in the mounting cavity 300. The body 10 is also provided with a first water inlet hole 301 communicating with the mounting cavity 300, and a second water inlet hole 201 and a liquid outlet hole 202 communicating with the liquid mixing cavity 200. The first water inlet hole 301 is configured to guide water to the mounting cavity 300 to drive the movable component 20 to add the foaming liquid to the liquid mixing cavity 200 through the liquid adding hole 500. The second water inlet hole 201 is configured to guide water to the liquid mixing cavity 200 and mix with the foaming liquid and then discharge from the liquid outlet hole 202.

[0054] Implementing the embodiments of the present disclosure will have the following beneficial effects:

[0055] The foaming device of the above scheme is applied to a toilet, which can avoid the need for the mixed liquid to stand for a period of time before being discharged, so that the toilet has an excellent foaming effect. Specifically, the foaming device includes a main body 10 provided with a liquid storage chamber 100, a mixing chamber 200 and a mounting chamber 300, and a movable component 20 movably mounted on the mounting chamber 300. Among them, a liquid inlet hole 400 is connected between the liquid storage chamber 100 and the mounting chamber 300, so that the foaming liquid can automatically enter the mounting chamber 300 under the action of gravity. A liquid adding hole 500 is connected between the mixing chamber 200 and the mounting chamber 300, so that the foaming liquid cannot be added to the mixing chamber 200 under the action of gravity, thereby avoiding the foaming liquid from being added to the mixing chamber 200 and mixing with water to form a mixed liquid before the foaming operation is performed, thereby avoiding the use of a mixed liquid that has been standing for a period of time when performing a foaming operation.

[0056] The main body 10 is also provided with a first water inlet hole 301 connected to the installation cavity 300, and a second water inlet hole 201 and a liquid outlet hole 202 connected to the mixing liquid cavity 200. The first water inlet hole 301 is configured to guide water to the installation cavity 300, so as to drive the movable component 20 to add the foaming liquid to the mixing liquid cavity 200 through the liquid adding hole 500. In this way, when the foaming operation is performed, the foaming liquid can be actively added to the mixing liquid cavity 200 by driving the movable component 20 through water, thereby avoiding the need to provide an independent liquid pump and saving costs. The second water inlet hole 201 is configured to guide water to the mixing liquid cavity 200 and mix with the foaming liquid, and then discharge it from the liquid outlet hole 202. In this way, when the foaming operation is performed, water and foaming liquid can be added to the mixing cavity at the same time or water and foaming liquid can be added separately in a short period of time, thereby avoiding the mixed liquid from being left stationary, resulting in a poor foaming effect. In addition, the volume of the foaming liquid added to the mixing chamber 200 can be adjusted by the moving distance of the movable component 20, and the moving distance of the movable component 20 can be controlled by limiting the moving range of the movable component 20 by the main body 10 and the water pressure of the water driving the movable component 20.

[0057] In the exemplary embodiment, please combine Figure 5 , Figure 7 and Figure 8 , the liquid storage chamber 100, the liquid inlet hole 400 and the mounting chamber 300 are arranged in sequence from top to bottom along the direction of gravity, so that the obstruction of the main body 10 to the flow of the foaming liquid from the liquid storage chamber 100 to the mounting chamber 300 can be reduced, so that the foaming liquid can flow more smoothly from the liquid storage chamber 100 to the mounting chamber 300. In the embodiment of the present disclosure, the number of the liquid inlet hole 400 is one. And the liquid inlet hole 400 is coaxially arranged with the liquid storage chamber 100, so that the foaming liquid in the liquid storage chamber 100 can flow into the liquid inlet hole 400 more evenly. In addition, in some embodiments, the number of the liquid inlet holes 400 can also be multiple, and the multiple liquid inlet holes 400 can be relatively evenly distributed between the liquid storage chamber 100 and the mounting chamber 300. The cross-section of the liquid inlet hole 400 can be a regular shape such as a circle, an ellipse, a triangle, a rectangle or a trapezoid, and the cross-section of the liquid inlet hole 400 can also be an irregular shape.

[0058] It can be understood that in other embodiments, the liquid storage chamber 100 and the mounting chamber 300 can also be arranged in a spatially staggered manner along the gravity direction. In this case, the liquid inlet hole 400 can be arranged horizontally or tilted downward from the liquid storage chamber 100 to the mounting chamber 300 to guide the foaming liquid to flow from the liquid storage chamber 100 into the mounting chamber 300.

[0059] In the exemplary embodiment, please combine Figures 6 to 8, the horizontal plane where the liquid adding hole 500 is located is located above the liquid storage chamber 100 along the gravity direction. In this way, the liquid inlet hole 400 and the installation cavity 300 connect the liquid adding hole 500 and the liquid storage chamber 100 to form a communicating vessel structure, and after the foaming liquid is added to the upper limit of the liquid storage chamber 100, the foaming liquid cannot rise to the liquid adding hole 500, thereby avoiding the foaming liquid from entering the mixing liquid chamber 200 when the foaming liquid is replenished to the liquid storage chamber 100. In addition, when replenishing the foaming liquid, there is no need to consider whether the foaming liquid rises to the liquid adding hole 500, so that the operator can focus more on replenishing the foaming liquid. The cross-section of the liquid adding hole 500 can be a regular shape such as a circle, an ellipse, a triangle, a rectangle or a trapezoid, and the cross-section of the liquid adding hole 500 can also be an irregular shape.

[0060] In an exemplary embodiment, please continue to refer to Figures 6 to 8 The horizontal plane where the liquid adding hole 500 is located is located above the liquid outlet hole 202 along the gravity direction, so that the mixed liquid cannot rise to the liquid adding hole 500 before being discharged from the liquid outlet hole 202, thereby preventing the mixed liquid from flowing back to the installation cavity 300 and contaminating the foaming liquid.

[0061] In the exemplary embodiment, please combine Figures 5 to 8 , the main body 10 is also provided with a liquid adding channel 501. The liquid adding channel 501 extends in the direction of gravity. In this way, the liquid adding channel 501 occupies a smaller space of the main body 10 in the horizontal direction, and the main body 10 is prevented from becoming thick and heavy due to the opening of the liquid adding channel 501. The liquid adding channel 501 is coaxially arranged with the liquid adding hole 500, and the liquid adding channel 501 is connected between the mounting cavity 300 and the liquid adding hole 500. In this way, it is possible to avoid structures such as corners between the liquid adding channel 501 and the liquid adding hole 500 that hinder the flow of the foaming liquid, so that the foaming liquid can enter the liquid adding hole 500 more smoothly from the liquid adding channel 501, thereby reducing the difficulty of driving the foaming liquid by the movable component 20. In the embodiment of the present disclosure, the flow area of ​​the liquid adding hole 500 and the liquid adding channel 501 is the same, which further improves the smoothness of the foaming liquid entering the liquid adding hole 500 from the liquid adding channel 501.

[0062] In the exemplary embodiment, please combine Figure 5 , Figure 7 and Figure 8 The main body 10 has a cavity wall 11 that encloses the installation cavity 300. The main body 10 also has a flow channel wall 12 that encloses the liquid adding flow channel 501, and the orthographic projection of the flow channel wall 12 along the gravity direction is located on the cavity wall 11. The cavity wall 11 has an end wall 111 located at one end of the installation cavity 300, and the orthographic projection of the flow channel wall 12 along the gravity direction is tangent to the end wall 111. In this way, the foaming liquid can directly enter the liquid adding flow channel 501 after contacting the end wall 111 under the drive of the movable component 20, making the process of the foaming liquid entering the liquid adding flow channel 501 from the installation cavity 300 smoother, reducing the difficulty of the movable component 20 in driving the foaming liquid.

[0063] In the exemplary embodiment, please combine Figures 1 to 3 and Figures 5 to 8 The main body 10 has a protrusion 13, and the liquid adding hole 500 is arranged on the protrusion 13. The main body 10 also has a groove bottom 14 and a circumferential wall 15. The circumferential wall 15 is arranged on the circumferential outer side of the groove bottom 14, and is surrounded by the groove bottom 14 to form a liquid adding groove 600. The protrusion 13 is at least partially accommodated in the liquid adding groove 600, and the groove bottom 14 and the protrusion 13 are arranged at intervals along the gravity direction, and the liquid adding hole 500 and the liquid mixing chamber 200 are connected through the liquid adding groove 600. In this way, through the arrangement of the liquid adding groove 600, the foaming liquid discharged from the liquid adding hole 500 can be introduced into the liquid mixing chamber 200 in a certain direction, ensuring that most of the foaming liquid can be mixed with water in the liquid mixing chamber 200. The groove bottom 14 and the protrusion 13 are arranged at intervals along the gravity direction, which can reduce the obstruction of the groove bottom 14 on the foaming liquid and ensure that the foaming liquid can smoothly enter the liquid adding groove 600 from the liquid adding hole 500. Part of the circumferential wall 15 protrudes toward the side away from the protrusion 13 , further facilitating the foaming liquid to enter the liquid mixing chamber 200 .

[0064] In an exemplary embodiment, please continue to refer to Figures 1 to 3 and Figures 5 to 8 The body 10 includes a shell 16 and a cover 17, and the shell 16 and the cover 17 enclose a liquid storage chamber 100 and a liquid mixing chamber 200. The shell 16 has a protrusion 13, and the liquid adding groove 600 is located on the cover 17. The cover 17 covers the shell 16, and the protrusion 13 is fitted with the circumferential wall 15. In this way, the positioning of the shell 16 and the cover 17 can be facilitated by the cooperation of the protrusion 13 and the circumferential wall 15, and the assembly efficiency between the shell 16 and the cover 17 can be improved. The side of the shell 16 facing the cover 17 has a sealing groove 700, and the sealing groove 700 is installed with a sealing member 18. The side of the cover 17 facing the shell 16 is provided with a convex strip 171, which can be inserted into the sealing groove 700, and the sealing member 18 is abutted against the shell 16 to ensure the sealing between the shell 16 and the cover 17. The cover 17 is provided with a first water inlet pipe 172 and a liquid outlet pipe 173. One end of the first water inlet pipe 172 is exposed on the side of the cover body 17 away from the shell 16 to facilitate external piping. The other end of the first water inlet pipe 172 is provided with a second water inlet hole 201, and the first water inlet pipe 172 extends into the mixing chamber 200 to place the second water inlet hole 201 in the mixing chamber 200. One end of the liquid outlet pipe 173 is exposed on the side of the cover body 17 away from the shell 16 to facilitate external piping. The other end of the liquid outlet pipe 173 is provided with a liquid outlet hole 202, and the liquid outlet pipe 173 extends into the mixing chamber 200 to place the liquid outlet hole 202 in the mixing chamber 200. Figure 2 As shown, the cover body 17 may also be provided with an exhaust pipe 174 communicating with the liquid mixing chamber 200 to prevent excessive pressure in the liquid mixing chamber 200 and prevent water and foaming liquid from entering the liquid mixing chamber 200 .

[0065] In the exemplary embodiment, please combine Figure 2 , Figure 3 and Figures 5 to 8 The shell 16 includes an outer wall 161 and a partition wall 162. The partition wall 162 is disposed between the liquid storage chamber 100 and the liquid mixing chamber 200, and isolates the liquid storage chamber 100 from the liquid mixing chamber 200. The protrusion 13 is disposed on the partition wall 162, and the liquid adding channel 501 is disposed on the partition wall 162. In this way, the structural strength of the outer wall 161 can be improved by disposing the partition wall 162, and the outer wall 161 can be prevented from being deformed during use, thereby affecting the sealing between the shell 16 and the cover body 17. The liquid adding channel 501 is formed on the partition wall 162, so that the liquid adding channel 501 is located between the liquid storage chamber 100 and the liquid mixing chamber 200, shortening the distance for the foaming liquid to enter the liquid mixing chamber 200 from the liquid storage chamber 100. In addition, the formation of the liquid adding channel 501 on the partition wall 162 can also avoid the additional addition of a structure enclosing the liquid adding channel 501, thereby further reducing costs. In the disclosed embodiment, the sealing groove 700 has an extension groove extending to the end of the partition wall 162 facing the cover body 17. Correspondingly, the convex strip 171 has an extension portion facing the extension groove, which can be inserted into the extension groove to abut the sealing member 18 against the partition wall 162.

[0066] In the exemplary embodiment, please combine Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 The body 10 further includes an end cover 19, which is located at one end of the installation cavity 300 away from the end wall 111. The end cover 19 and the shell 16 enclose the installation cavity 300 and are detachably connected to the shell 16. In this way, the installation of the movable component 20 can be facilitated by the arrangement of the end cover 19. The end cover 19 is provided with a second water inlet pipe 191. One end of the second water inlet pipe 191 is exposed on a side of the end cover 19 away from the installation cavity 300 to facilitate external piping. The first water inlet hole 301 is provided on the second water inlet pipe 191. In this way, the first water inlet hole 301 is located at the end of the installation cavity 300, so that the water entering the installation cavity 300 can drive the movable component 20.

[0067] In the exemplary embodiment, please combine Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8The movable component 20 includes a switching shaft 21 and a plurality of sealing rings 22. The plurality of sealing rings 22 are sleeved on the switching shaft 21 and are slidably sealed with the body 10, so that the sealing rings 22 can be prevented from being connected to both sides of the moving direction of the movable component 20. In the process of the movable component 20 adding the foaming liquid to the mixing liquid chamber 200 through the liquid adding hole 500, the plurality of sealing rings 22 cooperate with the body 10 to isolate the liquid inlet hole 400 from the liquid adding hole 500 and the first water inlet hole 301 respectively. In this way, the foaming liquid in the installation cavity 300 can be prevented from flowing back to the liquid storage chamber 100, affecting the volume of the foaming liquid added to the mixing liquid chamber 200 under the drive of the movable component 20, and water can also be prevented from entering the liquid storage chamber 100 to contaminate the foaming liquid.
