In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0066] The intelligent toilet has a main body and a pelvic cavity provided on the main body. Generally, a water tank can also be set on the main body, and the water in the water tank can be used to flush the dirt in the pelvic cavity. In order to clean the intelligent toilet and reduce the spread of pollutants, a foam shield system can be used to spray foam into the pelvic cavity. In some technologies, in order to make the foam cover the inner wall of the pelvic cavity and the water surface more fully, a foaming liquid storage box is installed in the intelligent toilet, and the foaming liquid is sprayed into the pelvic cavity through the foam shield system. Since the foaming liquid needs to be produced through a professional manufacturing process, the use cost of the intelligent toilet is greatly increased; when the foaming liquid is mixed with water during the spraying process, if the mixing of the foaming liquid is uneven, it is easy to cause waste of the foaming liquid, further increasing the use cost of the intelligent toilet.

[0067] In view of the problems of high use cost and easy waste of the foaming liquid in the intelligent toilet, the present application proposes a foam shield system that can be used in an intelligent toilet. By adopting a multi-stage mixing method, it is proposed to improve the uniformity of the cleaning agent; since the existing cleaning agent can be directly used without using a special foaming liquid, the use cost of the foam shield system can be reduced; by pre-mixing the cleaning agent and then performing secondary mixing, the use efficiency of the cleaning agent can be improved; and the use cost can be further reduced.

[0068] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in the figures, the foam shield system 20 in the examples of the present application can be installed on the main body 10 of the intelligent toilet. A nozzle 30 communicating with the foam shield system 20 can be set on the intelligent toilet. The foam shield system 20 can produce a mixed liquid of a cleaning agent and water, and spray the mixed liquid into the pelvic cavity 11 of the intelligent toilet through the nozzle 30 of the intelligent toilet. The intelligent toilet in this example can be provided with a water tank 12 and a liquid box 13. Among them, the water tank 12 can be used to store water, and the water tank 12 in this example can be connected to the municipal water pipe; the liquid box 13 can be used to store the cleaning agent, and the cleaning agent can be a cleaning agent dedicated to toilet cleaning, or a cleaning raw material with cleaning functions such as dishwashing liquid, hand sanitizer, and body wash.

[0069] Please refer to Figure 4 and Figure 5 As shown in the figures, an example of the foam shield system 20 proposed in the present application includes a first housing 21 and a second housing 22. The first housing 21 has a first chamber 211, and the first housing 21 has a liquid inlet hole 212 and a first liquid outlet hole 213 communicating with the first chamber 211; the second housing 22 is connected to the first housing 21, the second housing 22 forms a second chamber 221, the first liquid outlet hole 213 communicates with the second chamber 221, and the second housing 22 is provided with a second liquid outlet hole 228 communicating with the second chamber 221.

[0070] Please refer to Figure 6 and Figure 7, the first housing 21 is at least partially hollow to form a first chamber 211. The first chamber 211 can be a cavity with a regular shape or an irregular shape.

[0071] Please refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 , the first housing 21 has a liquid inlet hole 212 and a first liquid outlet hole 213 communicating with the first chamber 211. Among them, the liquid inlet hole 212 can be used to introduce a cleaning agent and a water source into the first chamber 211. In this example, the number of liquid inlet holes 212 can be one. The liquid inlet hole 212 can be connected to the liquid box 13 through a liquid inlet pipe 15, and the liquid inlet hole 212 can also be connected to the water tank 12 through a water inlet pipe 14. The cleaning agent and the water source can share the same liquid inlet hole 212. In some examples, the number of liquid inlet holes 212 can be at least two. Among them, at least one liquid inlet hole 212 is connected to the liquid box 13 through a liquid inlet pipe 15, and at least one liquid inlet hole 212 is connected to the water tank 12 through a water inlet pipe 14. The liquid inlet hole 212 in this example can be arranged facing the inner wall surface of the first chamber 211. The first liquid outlet hole 213 can be offset from the position of the liquid inlet hole 212. The first liquid outlet hole 213 is not directly opposite to the liquid inlet hole 212. After the cleaning agent and the water source enter the first chamber 211, they can be blocked by the inner wall surface of the first chamber 211, so that the cleaning agent and the water source generate a vortex in the first chamber 211, and at the same time, the residence time of the cleaning agent and the water source in the first chamber 211 can be extended, so that the cleaning agent and the water source can be fully mixed in the first chamber 211. The first chamber 211 in this example can be used to form a space for mixing the cleaning agent and the water source. When the cleaning agent and the water source enter the first chamber 211, under the shielding of the inner wall surface of the first chamber 211, the cleaning agent and the water source can generate a vortex in the first chamber 211, so that the cleaning agent and the water source can be mixed. With the full mixing of the cleaning agent, the waste of the cleaning agent can be reduced, the use efficiency of the cleaning agent can be improved, and the amount of the cleaning agent used can be reduced.

[0072] The second housing 22 is at least partially a hollow structure to form a second chamber 221. The second chamber 221 can be a cavity with a regular shape or an irregular shape. The second liquid outlet hole 228 is a through hole formed in the second housing 22. In this example, a pipe for outputting the mixed liquid can be provided on the second housing 22, and the second liquid outlet hole 228 can be formed in the pipe. The connection between the first housing 21 and the second housing 22 means that the first housing 21 can be directly or indirectly connected to the second housing 22. The direct connection between the first housing 21 and the second housing 22 means that the first housing 21 can be directly mounted on the second housing 22, and the first housing 21 can be at least partially located inside the second housing 22 so that the liquid output from the first liquid outlet hole 213 of the first housing 21 can directly enter the second chamber 221; the first housing 21 can also be located outside the second housing 22, and the first liquid outlet hole 213 communicates with the second chamber 221; when the first housing 21 is directly connected to the second housing 22, the first housing 21 and the second housing 22 can share a part of the wall surface to reduce the weight of the foam shield system 20 and improve the integration performance of the foam shield system 20; when the first housing 21 is indirectly connected to the second housing 22, a pipe can be provided between the first housing 21 and the second housing 22 to connect the first liquid outlet hole 213 and the second chamber 221 through the pipe.

[0073] Please refer to again Figure 11 , in this example, when the cleaner and the water source are mixed once in the first chamber 211, the mixed liquid enters the second chamber 221 through the first liquid outlet hole 213, and is mixed a second time in the second chamber 221. After the cleaner and the water source are fully mixed twice and then subsequent processing is carried out, the use efficiency of the cleaner can be effectively improved. The first liquid outlet hole 213 in this example can be a through hole with a preset fixed diameter, or the first liquid outlet hole 213 can also be a tapered hole. Optionally, the positions of the first liquid outlet hole 213 and the second liquid outlet hole 228 can be offset from each other, and the first liquid outlet hole 213 is not directly opposite to the second liquid outlet hole 228 to extend the flow time of the mixed liquid in the second chamber 221. Optionally, the second housing 22 has a third wall 222, and there is a gap between the first housing 21 and the third wall 222. The first liquid outlet hole 213 is arranged facing the third wall 222. The third wall 222 is used to block the mixed liquid output from the first liquid outlet hole 213 so that the mixed liquid output from the first liquid outlet hole 213 can generate a vortex in the gap between the third wall 222 and the first housing 21. During the process of the mixed liquid continuing to flow in the direction of the second liquid outlet hole 228, the mixed liquid can be further mixed so that the cleaner can be more fully dissolved, which helps to improve the use efficiency of the cleaner.

[0074] In the example of this application, the first mixing of the cleaning agent and the water source is carried out in the first chamber 211, and the secondary mixing of the cleaning agent and the water source is carried out through the second chamber 221, so that the cleaning agent can be fully dissolved in the water source, which can help reduce the dosage of the cleaning agent and improve the use efficiency of the cleaning agent; as the cleaning agent flows, the dosage of the cleaning agent required for single foaming is reduced; since the cleaning agent can be fully mixed, the fineness of the foam formed by foaming can be improved; in this example, household dishwashing liquid, hand sanitizer, body wash, etc. can be used to replace the traditional toilet-specific foam liquid as the foaming agent, which helps to improve the versatility, economy and environmental friendliness of the foam shield system 20.

[0075] In some examples, the foam shield system 20 further includes a foaming device 23 and an air inlet pipe 24. The foaming device 23 is disposed in the second chamber 221, and the second liquid outlet hole 228 is arranged corresponding to the position of the foaming device 23; the air inlet pipe 24 is connected to the foaming device 23, and the air inlet pipe 24 is used to connect to an air pump 28.

[0076] The foaming device 23 can be made of porous material. Optionally, the foaming device 23 in this example can include a bubble stone. The foaming device 23 is arranged in the second chamber 221 so that the mixed liquid entering the second chamber 221 can enter the foaming device 23 for foaming operation, so as to form foam from the mixed liquid. The air inlet pipe 24 is connected to the foaming device 23 and is used to deliver gas to the foaming device 23. In this example, the air inlet pipe 24 can be used to connect to the air pump 28, and the air pump 28 is used to pump air into the foaming device 23. The air pump 28 can be arranged on the second housing 22, and the air pump 28 can also be a pump body installed on the intelligent toilet. In some examples, the foam shield system 20 further includes an air pump 28, and the air pump 28 can be integrally installed on the second housing 22, and the output port of the air pump 28 is connected to the air inlet pipe 24.

[0077] The second liquid outlet hole 228 is arranged corresponding to the foaming device 23, which means that the opening position of the second liquid outlet hole 228 corresponds to the foaming device 23, so that the foam formed at the foaming device 23 can be output nearby through the second liquid outlet hole 228. Optionally, in this example, the second liquid outlet hole 228 can be arranged on the upper surface of the second housing 22 corresponding to the foaming device 23.

[0078] In this example, the installation position of the foaming device 23 can be determined according to the volume of the second housing 22 and the volume of the second chamber 221. Optionally, the foaming device 23 can be arranged at a position in the second chamber 221 far from the first liquid outlet hole 213 to extend the flow path of the mixed liquid in the second chamber 221, so that the cleaning agent can be mixed more fully.

[0079] Please continue to refer to Figure 11, in some examples, the first liquid outlet hole 213 is arranged towards the first direction 11a, the foaming device 23 is located on one side of the first liquid outlet hole 213 along the second direction 11b, and the second direction 11b is arranged at an angle to the first direction 11a.

[0080] The statement that the first liquid outlet hole 213 is arranged towards the first direction 11a means that the axial direction of the first liquid outlet hole 213 extends along the first direction 11a, and the liquid output from the first liquid outlet hole 213 can flow along the first direction 11a.

[0081] The statement that the first direction 11a is arranged at an angle to the second direction 11b means that the first direction 11a and the second direction 11b are not parallel. The foaming device 23 is located on one side of the first liquid outlet hole 213 along the second direction 11b, which means that the foaming device 23 is not directly opposite to the first liquid outlet hole 213, so that the mixed liquid output from the first liquid outlet hole 213 turns before flowing towards the foaming device 23. With the change of the liquid flow direction, the mixed liquid can be further and fully mixed, which helps to improve the uniformity of the mixed liquid and reduce the dosage of the cleaner. In some examples, the second housing 22 has the third wall 222 as described in the above examples. The third wall 222 is arranged on one side of the first liquid outlet hole 213 along the first direction 11a. The mixed liquid output from the first liquid outlet hole 213 flows along the first direction 11a to the third wall 222, and under the blockage of the third wall 222, the mixed liquid flows towards the foaming device 23.

[0082] In some examples, the liquid inlet hole 212 includes a first hole 2121. The first housing 21 includes a first wall 214, a second wall 215, and a side wall 216 connected between the first wall 214 and the second wall 215. At least part of the first wall 214 is arranged opposite to the second wall 215. The first wall 214, the second wall 215, and the side wall 216 enclose to form a first chamber 211. The first hole 2121 is opened on the first wall 214, and the first liquid outlet hole 213 is opened on the side wall 216.

[0083] The first hole 2121 can be a through hole penetrating the corresponding wall surface of the first housing 21.

[0084] The first wall 214 is spaced apart from the second wall 215, and at least part of the first wall 214 is disposed opposite to the second wall 215. In this example, the first wall 214 can be arranged parallel to the second wall 215, or the first wall 214 can be arranged at a certain angle to the second wall 215; a first hole 2121 is formed in the first wall 214. When the liquid is input into the first chamber 211 through the first hole 2121, the liquid continuously flows towards the second wall 215. When the liquid is blocked by the second wall 215, it will turn, and when the flow direction of the liquid changes, the liquid can be further mixed to make full use of the internal space of the first chamber 211. In this example, at least part of the first wall 214 is disposed opposite to the second wall 215. In this example, the first wall 214 can be arranged below the second wall 215, and the liquid enters the first chamber 211 through the first hole 2121 and flows upwards towards the second wall 215. Optionally, the first wall 214 can be arranged above the second wall 215, and the liquid can enter the first chamber 211 through the first hole 2121 and flow downwards towards the second wall 215; optionally, the first wall 214 and the second wall 215 can also be arranged left and right or front and back.

[0085] The side wall 216 is connected between the first wall 214 and the second wall 215. The side wall 216, the first wall 214 and the second wall 215 enclose the first chamber 211. In this example, the side wall 216 can generally enclose a quadrilateral structure, or the side wall 216 can enclose a circular or other polygonal shape. A first liquid outlet hole 213 is formed in the side wall 216 so that the first liquid outlet hole 213 can be misaligned with the first hole 2121, reducing the direct convection of the liquid output from the first hole 2121 between the first hole 2121 and the first liquid outlet hole 213, so as to extend the flow time of the liquid in the first chamber 211.

[0086] Please refer to Figure 10 After the liquid in this example is output through the first hole 2121, it is blocked by the second wall 215, and the liquid turns in the first chamber 211, so that the cleaning agent and the water source in the first chamber 211 can be fully mixed. In some examples, a structure for generating turbulent flow for the liquid can also be provided on the second wall 215. For example, ribs for generating turbulent flow can be provided on the second wall 215, and the ribs can be arranged corresponding to the first hole 2121. When the liquid enters the first chamber 211 through the first hole 2121 and flows towards the second wall 215, under the turbulent flow effect of the ribs, the liquid can generate turbulence at the second wall 215, so that the liquid can be further diffused, further improving the dispersibility of the cleaning agent and contributing to improving the uniformity and fineness of foaming.

[0087] Please refer to Figure 10, in some examples, the side wall 216 includes a first side wall 2161 and a second side wall 2162 disposed opposite to the first side wall 2161. The first side wall 2161 and the second side wall 2162 are respectively connected to the second wall 215, and the first liquid outlet hole 213 is provided on the first side wall 2161; the first wall 214 includes a bottom wall 2141, a connecting wall 2142, and a retaining rib 2143; the bottom wall 2141 is disposed opposite to the second wall 215, and the first side wall 2161 is connected to the bottom wall 2141; the connecting wall 2142 is connected to the bottom wall 2141 and extends in the direction of the second wall 215, and the connecting wall 2142 is spaced apart from the second wall 215; the retaining rib 2143 is connected to the second side wall 2162 and the end of the connecting wall 2142 away from the bottom wall 2141, and is disposed opposite to the second wall 215; the bottom wall 2141, the first side wall 2161, the second wall 215, the second side wall 2162, the retaining rib 2143, and the connecting wall 2142 enclose a first chamber 211; a first hole 2121 is provided on the retaining rib 2143.

[0088] The relative arrangement of the first side wall 2161 and the second side wall 2162 means that there is a space between the first side wall 2161 and the second side wall 2162, and the first wall 214 is located between the first side wall 2161 and the second side wall 2162. In this example, the first wall 214 and the second wall 215 may be arranged in parallel.

[0089] The bottom wall 2141 is connected to the first side wall 2161, the retaining rib 2143 is connected to the second side wall 2162, and the connecting wall 2142 is used to connect between the bottom wall 2141 and the retaining rib 2143. In this example, the bottom wall 2141 and the retaining rib 2143 may be respectively disposed opposite to the second wall 215, and the bottom wall 2141, the connecting wall 2142, and the retaining rib 2143 together constitute the first wall 214. A first hole 2121 is provided on the retaining rib 2143. In this example, the retaining rib 2143 is closer to the second wall 215 than the bottom wall 2141. After the liquid enters the first chamber 211 through the first hole 2121, the liquid can flow to the second wall 215 nearby and turn under the blockage of the second wall 215, so that the liquid can form a vortex in the first chamber 211, so that the cleaner can be mixed in the second chamber 221. The first hole 2121 in this example can be used to input the cleaner or the water source, and the first hole 2121 can also be used to input a mixture of the cleaner and the water source.

[0090] In this example, the first liquid outlet hole 213 can be arranged at any position on the first side wall 2161. Optionally, the distance between the first liquid outlet hole 213 and the second wall 215 is not less than the distance between the baffle rib 2143 and the second wall 215. The first liquid outlet hole 213 can be arranged at a position on the first side wall 2161 far from the second wall 215 to extend the flow path of the liquid from the second wall 215 to the first liquid outlet hole 213. In some examples, the first liquid outlet hole 213 can be arranged facing the connecting wall 2142. When the liquid flows from the second wall 215 towards the first liquid outlet hole 213, it can flow towards the first wall 214 under the action of the first side wall 2161. Blocked by the first side wall 2161, the cleaning agent is further mixed with water in the area between the first side wall 2161 and the connecting wall 2142.

[0091] In some examples, the liquid inlet hole 212 further includes a second hole 2122 arranged at an interval from the first hole 2121, and the second hole 2122 is opened in one of the first side wall 2161, the second wall 215, the second side wall 2162 or the baffle rib 2143.

[0092] The second hole 2122 in this example can cooperate with the first hole 2121. Among them, the first hole 2121 and the second hole 2122 can be respectively used to input the cleaning agent and the water source into the first chamber 211. In this example, the cleaning agent and the water source are respectively input into the first chamber 211 through independent holes. The second hole 2122 in this example can be arranged on the first side wall 2161, the second side wall 2162, the second wall 215 or the baffle rib 2143. Taking the first hole 2121 for inputting the cleaning agent and the second hole 2122 for inputting the cleaning agent as an example, when the water source flows from the first hole 2121 towards the second wall 215, the cleaning agent can be input into the first chamber 211 from the first side wall 2161, the second wall 215 or the second side wall 2162, and the water source is input through the first hole 2121 to make the water source and the cleaning agent collide on the output path of the cleaning agent, so that the water source can disperse the cleaning agent, which helps to improve the dispersibility of the cleaning agent. In some examples, the second hole 2122 is opened on the baffle rib 2143, and the cleaning agent and the water source can both flow towards the second wall 215. The second wall 215 blocks the cleaning agent and the water source to mix the cleaning agent and the water source.

[0093] In some examples, the first wall 214 is integrally provided with the second housing 22. The first wall 214 in this example can be a wall surface on the second housing 22. The first housing 21 and the second housing 22 can share a wall surface to reduce the connection difficulty between the first housing 21 and the second housing 22 and reduce the structural complexity. The first housing 21 in this example can be located inside the second chamber 221 to facilitate reducing the structural complexity of the foam shield system 20. The first liquid outlet hole 213 can be directly connected to the second chamber 221 so that the mixed liquid can be directly output into the second chamber 221 through the first liquid outlet hole 213 without the need to provide an intermediate connecting member between the first liquid outlet hole 213 and the second chamber 221. Optionally, the second wall 215 can be detachably connected to the first housing 21 so that the second wall 215, the side wall 216, and the first wall 214 enclose to form the first chamber 211.

[0094] Please refer to Figure 5 and Figure 12 In some examples, the foam shield system 20 further includes a water pump 26. The water pump 26 is connected to the second housing 22, and the water pump 26 communicates with the liquid inlet hole 212 for pumping water into the liquid inlet hole 212; the water pump 26 is used for pumping water into the first chamber 211. In this example, the water pump 26 can be connected to the water tank 12 of the smart toilet through the water inlet pipe 14. The water pump 26 can be fixedly connected or detachably connected to the second housing 22 to integrate the water pumping structure on the foam shield system 20 for convenient integrated control.

[0095] In some examples, the foam shield system 20 further includes a liquid pump 27.

At least a part of the second housing 22 is a hollow structure, and the partition 223 is installed in the hollow part of the second housing 22 to divide the hollow part of the second housing 22 into a second chamber 221 and an electrical compartment 224. Among them, the second chamber 221 can be used for mixing and foaming the mixture of the cleaner and the water source, and the electrical compartment 224 can be used to accommodate the main control board 25. In this example, by forming the electrical compartment 224, it is convenient to integrate the main control board 25 into the second housing 22 to improve the integration performance of the foam shield system 20; due to the blocking of the partition 223, the main control board 25 can be isolated from the second chamber 221 to prevent the liquid in the second chamber 221 from affecting the main control board 25, which helps to improve the safety of the foam shield system 20.
