[0002] With the continuous popularity of intelligent closestools, users are no longer satisfied with the basic functions of the seat heating, water temperature heating, drying and cleaning of the intelligent closestools, and the intelligent closestools need to increase other additional functions to be more popular among users, such as foam shield odor isolation and the like. At present, the foam shield cleaning mode of the intelligent closestool is to spray through different spray outlets to realize the two functions. The realization of the two functions through different spray outlets makes the module structure too complex, occupies too much space of the intelligent closestool, and the overall structure is not good for layout, and the actual use effect is not good.

[0039] The technical scheme of the utility model will be described in detail below with specific embodiments. The following several specific embodiments can be combined or replaced according to the actual situation, and the same or similar concepts or processes may not be described in some embodiments.

[0040] As Figures 1 to 4The utility model provides a foaming device of intelligent closestool, including water supply component and water pipe component 3 of water transport to closestool nozzle 41 in water supply component, be equipped with connecting piece 1 between water supply component and water pipe component 3, connecting piece 1 includes the first interface 11 of water supply component connection, the second interface 12 of water pipe component 3 connection and cleaning ball placement area 13, cleaning ball placement area 13 intercommunication first interface 11 and second interface 12.

[0041] It can be understood that connecting piece 1 is equipped with cleaning ball placement area 13, and connecting piece 1 intercommunicates water supply component and water pipe component 3, so that the cleaning ball is placed on the water flow path, the cleaning ball contains cleaning agent, so when the water flows, the cleaning agent water will dissolve in water, so that it forms the mixed water flow of water and cleaning agent, which not only saves the additional cleaning agent storage device, but also saves the power source needed to transport the cleaning agent into the water pipe component 3, saves manufacturing cost and has simple structure, and therefore the overall volume of the closestool can also be correspondingly reduced, so that the overall structure is more compact, and the cleaning ball will only dissolve when water flows, so even after a long period of use, the phenomenon of pipe blockage will not occur.

[0042] It should be noted that connecting piece 1 includes a placement channel 14 that communicates with the cleaning ball placement area 13, the placement channel 14 extends from the cleaning ball placement area 13 to the outer surface of the connecting piece 1, and the placement channel 14 is provided with a plug 2 that is sealingly fitted between the inner wall of the placement channel 14.

[0043] In this way, the user can conveniently place or remove the cleaning ball by removing the plug 2, and the plug 2 and the inner wall of the placement channel 14 are provided with a sealing element 21 to ensure the sealing of the connecting piece 1 and prevent water from leaking from the placement channel 14.

[0044] Because the water flow has a high flow rate during the process of flowing from the first interface 11 to the second interface 12, the cleaning ball will be impacted by the water flow, and in order to stabilize the placement of the cleaning ball in the cleaning ball placement area 13 and prevent it from being washed away by the water flow, a limiting portion 121 is provided at the second interface 12 to increase the protection of the cleaning ball and prevent it from moving from the cleaning ball placement area 13 to the water pipe component 3.

[0045] Specifically, the limiting portion 121 described above is a filter screen in this embodiment.

[0046] However, the limiting portion 121 can also be a baffle or other structure as long as it can achieve the purpose of limiting and is within the scope of protection of the utility model.

[0047] For the stable placement of the cleaning ball in the cleaning ball placement area 13, the following implementation modes can also be used:

[0048] 1. Limiting parts 121 are provided at both the first interface 11 and the second interface 12. Although the direction of water flow is from the first interface 11 to the second interface 12, the water flow impacting the cavity wall will generate turbulence in the cavity and cause water flow fluctuations. The water flow fluctuations will drive the cleaning ball to move towards the first interface 11. Therefore, limiting parts 121 are provided at both the first interface 11 and the second interface 12 to better prevent the cleaning ball from being washed away from the cleaning ball placement area 13.

[0049] 2. A mesh cover is installed at the bottom of the plug 2 to cover the cleaning ball. When the water flows from the first interface 11 to the second interface 12, the water flow speed is relatively fast, so the cleaning ball will be subjected to the impact force of the water flow. Therefore, installing a mesh cover at the bottom of the plug 2 can prevent the cleaning ball from being washed away from the cleaning ball placement area 13 by the water flow, and avoid the cleaning ball from moving to the water pipe assembly 3 and causing blockage of the water pipe assembly 3;

[0050] 3. The cleaning ball placement area 13 is recessed relative to the first interface 11 and the second interface 12 to form a concave cavity. The concave cavity can stabilize the placement of the cleaning ball in the cleaning ball placement area 13 and reduce the occurrence of the cleaning ball being swept away from the cleaning ball placement area 13 by the impact force generated during the flow of water from the first interface 11 to the second interface 12.

[0051] Furthermore, the formed cavity can also be used to restrict the movement of the cleaning ball. Under the impact of water flow, the cleaning ball may still move out of the cavity with the help of the water flow impact force and buoyancy. In this solution, the bottom end of the plug 2 (the direction described in the embodiment is consistent with the direction indicated in the figure) is lower than the upper edge of the first interface 11 and the second interface 12 and higher than the lower edge of the first interface 11 and the second interface 12. This does not affect the flow of water, and can also bring the distance between the bottom end of the plug 2 and the cavity opening closer, restricting the cleaning ball from moving out of the cavity and preventing it from being washed away from the cleaning ball placement area 13. Moreover, the bottom end of the plug 2 is higher than the lower edge of the first interface 11 and the second interface 12, so that while limiting the cleaning ball, it will not hinder the smooth flow of water.

[0052] The filter screen, mesh cover, and concave cavity mentioned above not only prevent the cleaning balls from being washed away from the cleaning ball placement area 13, but also generate turbulence when the water flows through the filter screen, mesh cover, and concave cavity respectively, so as to fully mix the cleaning agent and water. The fully mixed water can make the foaming more uniform, avoid waste of cleaning agent, and improve cleaning efficiency and cleaning agent utilization.

[0053] In this embodiment, the plug 2 includes a large diameter section 23 and a small diameter section 24. The large diameter section 23 and the small diameter section 24 are connected and transitioned by a horn structure 25. The placement channel 14 is provided with an abutting part 141 that abuts against the horn structure 25. The sealing member 21 is provided in the small diameter section 24 and located below the horn structure 25.

[0054] When the plug 2 is placed in the placement channel 14, the trumpet structure 25 abuts against the abutting portion 141, so that the downward movement of the plug 2 during the process of being inserted into the placement channel 14 is limited and cannot be excessively inserted downward, thereby avoiding the crushing of the cleaning ball due to the compression of the plug 2; meanwhile, the plug 2 cannot be insufficiently inserted, so that the bottom end of the plug 2 does not contact the cleaning ball, thereby causing the cleaning ball to be loose in the cleaning ball placement area 13. The abutment of the trumpet structure 25 of the plug 2 and the abutting portion 141 in the placement channel 14 not only achieves the limiting function of the plug 2, but also facilitates the user to install the plug 2 in the placement channel 14 at a proper position.

[0055] And the sealing of the sealing member 21 also ensures the sealing of the connecting piece 1.

[0056] Specifically, the sealing member 21 is a sealing ring, which not only ensures the sealing function of the connecting piece 1, but also enables the plug 2 to be in interference fit with the inner wall surface of the placement channel 14, so that the plug 2 is tightly and stably connected with the placement channel 14; the plug 2 and the placement channel 14 can also be connected by thread cooperation, which can also achieve the purpose of tight and stable connection.

[0057] On the basis of the above, Figure 2 and Figure 4 As shown, the placement channel 14 forms a placement opening 142 on the outer surface of the connecting piece 1, and the top end of the plug 2 is flush with the placement opening 142.

[0058] The top end of the placement channel 14 forms the placement opening 142 for placing or taking the cleaning ball, and the top end of the plug 2 is flush with the placement opening 142, which ensures the flatness of the top surface of the toilet, and such a structure also makes the surface of the toilet easy to clean and avoids leaving dead angles that are difficult to clean, and also avoids causing a step span in height and scratching the user during use.

[0059] Specifically, in order to save materials and reduce the weight of the plug, the inside of the plug 2 is provided with a hollow cavity, and the hollow cavity is provided with a "cross" type operating rib 26, so that the user can conveniently take out the plug 2 from the placement channel 14 by holding the operating rib 26.

[0060] The water pipe assembly 3 mentioned above includes a first water inlet pipe 31, a foaming pipe 32 and a second water inlet pipe 33 connected in sequence along the water flow direction, one end of the first water inlet pipe 31 is in communication with the second interface 12, and one end of the second water inlet pipe 33 is in communication with the toilet nozzle 41.

[0061] The foaming pipe 32 comprises a water inlet end 323, a throat 321 and a water outlet end 324, the throat 321 is located between the water inlet end 323 and the water outlet end 324, and the inner diameter of the throat 321 is smaller than the inner diameter of the water inlet end 323 and the water outlet end 324. The water inlet end of the foaming pipe 32 is provided with a contraction channel 322 which is contracted along the water flow direction. The contraction channel 322 is located in the water outlet end 324.

[0062] The contraction channel 322 is formed by a contraction pipe 325 located at the water inlet end of the foaming pipe 32.

[0063] The foaming process of the mixed water flow of the mixed cleaning agent in the water pipe assembly 3 is as follows:

[0064] Firstly, the water flow flows into the water inlet end of the foaming pipe 32 from the first water inlet pipe 31, and passes through the contraction channel 322 which is gradually contracted along the water flow direction. During the process that the water flow gradually passes through the smaller channel from the wider channel, the flow rate increases, and therefore the impact force of the water flow on the inner wall of the foaming pipe 32 also increases, which promotes the foaming effect between the water and the cleaning agent, and realizes the first foaming.

[0065] Further, when the mixed water flow after the first foaming gradually flows to the throat 321 of the foaming pipe 32, the water flow again passes through the smaller throat 321 from the wider channel between the contraction channel 322 and the throat 321, and the flow rate increases again. Therefore, the water flow impacts on the inner wall of the foaming pipe 32, so that the mixed water flow can be more fully mixed and foamed, which not only improves the cleaning efficiency, but also improves the use rate of the cleaning agent.

[0066] Preferably, the foaming pipe 32 is further provided with an air inlet channel 333 which is connected between the outside and the foaming pipe 32, and the air inlet channel 333 is located between the throat 321 and the contraction channel 322.

[0067] The air inlet channel 333 is formed by an air inlet pipe.

[0068] During the process that the water flow passes through the contraction channel 322, the flow rate gradually increases, and therefore a negative pressure is generated when the water flow passes through the contraction channel 322. Therefore, the air inlet channel 333 is located between the throat 321 and the contraction channel 322, and the negative pressure generated by the larger flow rate can suck the air from the outside into the foaming pipe 32. The sucked air is fully mixed with the mixed water flow which has been preliminarily foamed, which strengthens the foaming effect, makes the foam more dense and stable, and improves the utilization rate of the cleaning agent.

[0069] In order to avoid loosening between the first water pipe and the second water pipe relative to the foaming pipe 32 under the impact of water flow and in the long-term use process, the side wall of the water inlet end 323 and the side wall of the water outlet end 324 of the foaming pipe 32 are both provided with a limiting groove 334 arranged in the circumferential direction, and the first water inlet pipe 31 and the second water inlet pipe 33 are both provided with a third limiting part matched with the limiting groove 334, so as to realize the circumferential positioning of the first water inlet pipe 31 and the second water inlet pipe 33, which is helpful to maintain the stability of the water pipe assembly 3.

[0070] The embodiment also relates to an intelligent toilet, which comprises a toilet body 4, and the foaming device is mounted on the toilet body 4.

[0071] When the foaming device works, the mixed water flow after foaming is finally discharged to the wave surface of the toilet body 4 through the toilet nozzle 41 by the second water inlet pipe 33, so that the toilet is cleaned, then secondary cleaning is carried out, and the foam of the mixed water flow is floated on the water seal surface of the toilet, so that the splashing and odor isolation purposes are achieved.

[0072] In addition to the preferred embodiment, the utility model also has other implementation manners, and all other embodiments obtained by the person skilled in the art based on the embodiments in the utility model without creative labor belong to the range of the utility model.
