Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0060] The air purification device disclosed in the present application includes a shell, in which a first chamber connected to each other, an air inlet connected to the first chamber, a second chamber and an air outlet connected to the second chamber are formed. The air purification device can have an adsorption module and a water washing module, wherein the adsorption module can be installed in the first chamber of the shell, and the water washing module can be installed in the second chamber of the shell. The gas in the toilet bowl cavity can enter the first chamber from the air inlet, and after being adsorbed and deodorized by the adsorption module, it enters the second chamber, and the gas is washed by the water washing module, and the purified gas is output from the air outlet. Since the air purification is performed twice by the adsorption module and the water washing module, the air purification efficiency can be effectively improved, the odor in the toilet bowl cavity can be reduced, and the cleaning performance of the toilet can be improved.

[0061] See also Figure 1 The air purification device 20 in the present application can be used in a smart toilet. The air purification device 20 can be installed beside the control module or flush module of the smart toilet. By purifying the gas in the pelvic cavity 110, the odor of the smart toilet can be reduced.

[0062] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The present application proposes an air purification device 20 for a smart toilet, the air purification device 20 includes a shell 21, a partition 22 and a fan 23, the shell 21 has a fluid channel 215 and an air inlet 213 and an air outlet 214 connected to the fluid channel 215; the partition 22 is arranged in the fluid channel 215, the partition 22 separates the fluid channel 215 to form a first chamber 216 and a second chamber 217 that are connected to each other, the air inlet 213 is connected to the first chamber 216, the air outlet 214 is connected to the second chamber 217, the first chamber 216 is used to place the adsorption module 24, and the second chamber 217 is used to place the water washing module 25; the fan 23 is connected to the shell 21, and the fan 23 is used to pump the airflow in the fluid channel 215 from the air inlet 213 to the air outlet 214.

[0063] Please refer to Figure 6 , Figure 7 and Figure 8The shell 21 is an external frame structure of the air purification device 20. The interior of the shell 21 is at least partially hollow to form a fluid channel 215. The air inlet 213 and the air outlet 214 are through holes opened on the shell 21. The air inlet 213 and the air outlet 214 are connected to the fluid channel 215 respectively. The air flow input from the air inlet 213 can flow along the fluid channel 215 to the air outlet 214. The air inlet 213 in the example of the present application can be connected to the pelvic cavity 110 of the smart toilet, and the air inlet 213 can be arranged toward the bottom of the pelvic cavity 110 of the smart toilet, so that the gas in the smart toilet can enter the fluid channel 215. The air outlet 214 in the example of the present application can be connected to the outside of the smart toilet, and the air outlet 214 can also be connected to the inside of the smart toilet, so as to circulate the air flow into the smart toilet after purification.

[0064] See also Figure 7 and Figure 8 The fan 23 is connected to the housing 21, and at least one of the air inlet 213, the air outlet 214, and the fluid channel 215 is provided with the fan 23. The fan 23 is used to drive the gas flow so that the gas can flow from the air inlet 213 to the air outlet 214. The fan 23 in the example of the present application can be at least one of an axial flow fan, a vortex fan, or a cross flow fan.

[0065] The partition 22 is connected to the shell 21, and the partition 22 is located in the fluid channel 215 to separate the fluid channel 215 to form a first chamber 216 and a second chamber 217 that are independent of each other. The partition 22 can be used to prevent the liquid in the second chamber 217 from entering the first chamber 216, wherein the air inlet 213 is connected to the first chamber 216, and the air outlet 214 is connected to the second chamber 217. The air flow can enter the fluid channel 215 from the air inlet 213, and flow through the first chamber 216 and the second chamber 217 in sequence, and be output from the air outlet 214.

[0066] The first chamber 216 is used to place the adsorption module 24, and the adsorption module 24 can be an activated carbon or other module that can adsorb and purify the airflow. Optionally, the adsorption module 24 can also be a composite filter element composed of honeycomb ceramics or a combination of multiple adsorption and purification structures. The adsorption module 24 is used to adsorb particulate matter in the air. After the airflow passes through the adsorption module 24, the content of particulate matter in the airflow will be relatively reduced. With the adsorption effect of the adsorption module 24, the pungent odor in the airflow will also be relatively reduced. The adsorption module 24 in this example can be directly placed in the first chamber 216; the adsorption module 24 can also be interconnected with the inner wall surface of the first chamber 216. Optionally, the adsorption module 24 is detachably connected to the inner wall surface of the first chamber 216 so that the adsorption module 24 can be replaced when needed.

[0067] The second chamber 217 is used to place the water washing module 25, which is used to wash the air with water to dissolve and adsorb impurities in the air by water, thereby improving the cleaning efficiency of the air purification device 20. In this example, the first chamber 216 and the second chamber 217 are separated from each other, and optionally, the first chamber 216 and the second chamber 217 can be connected by a pipeline or a valve. In some examples, the first chamber 216 can be located above the second chamber 217; in some examples, the gas flows along the flow direction of the air flow channel, and the housing 21 has a front end and a rear end, wherein the air inlet 213 can be located at the front end of the housing 21, and the air outlet 214 can be set away from the front end of the housing 21. Optionally, the air outlet 214 can be set at the rear end of the housing 21, and the direction from the front end to the rear end can be horizontal or approximately horizontal. The second chamber 217 can be set closer to the rear end of the housing 21, and the first chamber 216 is located on the air inlet side of the second chamber 217 in the housing 21. The water washing module 25 can directly contact the air to be purified by infiltration, spraying, etc. The water washing module 25 can also be mixed with the air after atomization to absorb and dissolve impurities in the air; optionally, the water washing module 25 can also cooperate with other functional modules to form a water curtain in the second chamber 217, and the airflow output from the first chamber 216 flows toward the air outlet 214 after passing through the water curtain. The number of water curtains can be multiple. Optionally, the water washing module 25 can also be a water storage structure with water storage performance, and the gas output from the first chamber 216 can be injected into the water storage structure, and the impurities in the air can be dissolved in the water, and the air overflows from the water and flows toward the air outlet 214. During the use of the smart toilet, substances such as ammonia, hydrogen sulfide, and methyl mercaptan are generated. In this example, the gas is first adsorbed by the adsorption module 24 in the first chamber 216 to reduce the content of methyl mercaptan in the gas; the gas is input into the second chamber 217 for water washing, and water-soluble substances such as ammonia and hydrogen sulfide can be removed under the action of the water washing module 25, thereby reducing the content of harmful gases in the smart toilet. In the example of this application, the air outlet 214 and the air inlet 213 can be connected by a pipeline or a valve to recirculate the gas output from the air outlet 214 and input it into the air inlet 213 of the air purification device for circulation purification, thereby improving the air purification efficiency.

[0068] Optionally, the shell 21 has a height direction, and the height direction can be a first direction 2a. The first chamber 216 and the second chamber 217 can be arranged along a second direction 2b, and the second direction 2b is set at an angle to the first direction 2a, that is, the second direction 2b is not parallel to the first direction 2a. Optionally, the first direction 2a can be perpendicular to the second direction 2b. In this example, the first direction 2a is taken as a vertical direction, and the second direction 2b can be a horizontal direction.

[0069] In the example of the present application, in the airflow path, the air can first be adsorbed and purified by the adsorption module 24 in the first chamber 216, and then the air can be secondary cleaned by the water washing module 25. Taking activated carbon as an example, the adsorption effect of the adsorption module 24 with adsorption effect will be affected by the part that is wetted by water. Since the adsorption module 24 and the water washing module 25 are respectively located in two independent chambers, the influence of the water washing module 25 on the adsorption module 24 can be reduced, thereby reducing the problem of weakened adsorption capacity of the adsorption module 24 due to water contact.

[0070] Please refer to Figure 2 and Figure 3 In some examples, the shell 21 includes a first shell 211 and a second shell 212 that are arranged opposite to each other, the first shell 211 and the second shell 212 enclose a fluid channel 215, and the partition 22 is connected to the first shell 211 or the second shell 212; an air inlet 213 is opened on the first shell 211 or the second shell 212, and an air outlet 214 is opened on the first shell 211 or the second shell 212.

[0071] The first shell 211 and the second shell 212 are arranged opposite to each other so that the first shell 211 and the second shell 212 can be connected to each other. In this example, the first shell 211 and the second shell 212 can be connected to each other by screws, snaps or locks. The first shell 211 and the second shell 212 enclose a fluid channel 215. The fan 23 in this example can be connected to at least one of the first shells 211 to fix the fan 23 at a preset position on the shell 21. The first shell 211 and the second shell 212 in this example can be connected to each other by intermediate connectors such as screws and snaps. The first shell 211 and the second shell 212 can also be plugged into or embedded in each other. In this example, the first shell 211 and the second shell 212 are combined to form the shell 21, so that the first shell 211 and the second shell 212 can be formed separately and then docked to facilitate the molding of the first shell 211 and the second shell 212. Taking compression molding as an example, the first shell 211 and the second shell 212 can be molded by molds respectively to facilitate mold opening and reduce the molding difficulty of the first shell 211 and the second shell 212. During subsequent maintenance, the first shell 211 or the second shell 212 can be easily replaced separately to reduce maintenance costs.

[0072] The partition 22 may be connected to at least one of the first shell 211 and the second shell 212, so that the partition 22 blocks the fluid channel 215. In this example, the first shell 211 is on the top and the second shell 212 is on the bottom. The partition 22 may be connected to the second shell 212 so that the partition 22 may protrude from the bottom to the top, and the partition 22 may prevent the liquid in the second chamber 217 from entering the first chamber 216. Optionally, the partition 22 may be integrally provided with the second shell 212.

[0073] The air inlet 213 is provided on the first shell 211 or the second shell 212 , which means that the air inlet 213 can be provided on the first shell 211 or the second shell 212 , and the air inlet 213 can also be an opening of the connecting fluid channel 215 formed by the first shell 211 and the second shell 212 .

[0074] The air outlet 214 is provided on the first shell 211 or the second shell 212 , which means that the air outlet 214 can be provided on the first shell 211 or the second shell 212 , and the air outlet 214 can also be an opening of the connecting fluid channel 215 formed by the first shell 211 and the second shell 212 .

[0075] In some examples, the first shell 211 is arranged above the second shell 212. In this example, the first shell 211 and the second shell 212 are arranged up and down, and the first shell 211 and the second shell 212 are connected to each other to form a fluid channel 215. Optionally, the air inlet 213 in this example can be arranged on the second shell 212 so that the air inlet 213 can be oriented toward the bottom direction of the pelvic cavity 110 of the smart toilet. The second shell 212 in this example can be integrated on the movement base of the smart toilet, and the second shell 212 can also be used as a part of the movement base of the smart toilet. The movement base of the smart toilet can also be used to connect other functional components such as a water pump and a main control board, and reference can be made to the relevant technology.

[0076] In some examples, the first shell 211 is arranged above the second shell 212, and the air outlet 214 can be arranged on the second shell 212. On the one hand, the gas outputted from the air outlet 214 can flow into the inside of the smart toilet. On the other hand, the sewage generated by the washing module 25 in the second chamber 217 can flow downward to the air outlet 214 and flow in a preset direction along the air outlet 214. The air outlet 214 can have the functions of both airflow output and sewage output to simplify the structure of the shell 21. On the other hand, the sewage generated by washing can be discharged downward, which can reduce the problem of bacteria breeding and secondary pollution caused by the accumulation of sewage in the shell 21. In this example, the water outputted from the air outlet 214 can be transported to the water tank or pelvic cavity of the smart toilet. Since the airflow enters the second chamber 217 from the first chamber 216, the airflow flows toward the surface direction of the second shell 212 after passing through the washing module 25, which can extend the flow path of the airflow in the second chamber 217, so that the airflow can enter the washing module 25 more for washing. In some examples, the bottom wall of the second shell 212 can be inclined so that water can flow along the bottom wall of the second shell 212 toward the air outlet 214. Optionally, the distance between the bottom wall of the second shell 212 and the first shell 212 gradually increases from the partition 22 toward the air outlet 214, so that water can be gradually concentrated and output in the direction of the air outlet 214.

[0077] In some examples, the partition 22 is connected to the second shell 212 and extends toward the first shell 211, and one end of the partition 22 away from the second shell 212 is higher than the bottom wall of the second chamber 217. The partition 22 in this example can be generally protruding from bottom to top, so that the partition 22 blocks the first chamber 216 and the second chamber 217. The partition 22 can be a sheet structure connected to the second shell 212, or a rib structure protruding from the surface of the second shell 212 on one side facing the first shell 211.

[0078] The end of the partition 22 away from the second shell 212 may be the upper end of the partition 22. The bottom wall of the second chamber 217 may be the bottom surface of the second chamber 217 for supporting the water washing module 25. The upper end of the partition 22 is higher than the bottom wall of the second chamber 217, so that the upper end of the partition 22 is higher than the bottom of the water washing module 25. The partition 22 can prevent the water in the second chamber 217 from entering the first chamber 216.

[0079] In some examples, the direction from the second shell 212 to the first shell 211 is the first direction 2a, the first chamber 216 and the second chamber 217 are arranged along the second direction 2b, and the second direction 2b is set at an angle to the first direction 2a. In this example, the first direction 2a can be the height direction of the shell 21, and the second direction 2b can be the length direction or width direction of the shell 21. The first direction 2a and the second direction 2b are set at an angle, which means that the first direction 2a and the second direction 2b are not parallel. In this example, by arranging the first chamber 216 and the second chamber 217 along the second direction 2b, the adsorption module 24 and the water washing module 25 can be staggered with each other along the length or width direction of the shell 21. On the one hand, the possibility of sewage generated by the water washing module 25 entering the first chamber 216 can be reduced. On the other hand, the influence of the humid airflow on the adsorption module 24 can be reduced, and the problem of reduced adsorption capacity due to moisture in the adsorption module 24 can be reduced.

[0080] In some examples, the air inlet 213 and the air outlet 214 are respectively located at two ends of the housing 21 along the second direction 2b. In this example, the air inlet 213 and the air outlet 214 are arranged at two ends of the housing 21 in the second direction 2b, so that the air inlet 213 and the air outlet 214 are mutually staggered in the second direction 2b of the housing 21 to improve the air purification efficiency. When the air purification device 20 in this example is installed on the smart toilet, the air inlet 213 is connected to the pelvic cavity 110, and the air outlet 214 can be located at the end of the shell 21 away from the pelvic cavity 110. The second direction 2b can be the front-to-back direction of the smart toilet, and the air outlet 214 can be connected to the interior of the smart toilet to circulate the purified airflow; the air outlet 214 can also be connected to the outside of the smart toilet, and the second direction 2b can be a direction with a certain angle to the front-to-back direction of the smart toilet. For example, the air outlet 214 can be connected to the side wall of the smart toilet to output the purified gas to the outside, or the air outlet 214 can be connected to the interior of the smart toilet to clean the interior of the smart toilet with the purified airflow, thereby reducing the odor and bacterial growth of the smart toilet.

[0081] See also Figure 7 and Figure 8 In some examples, the fan 23 is arranged near the air inlet 213. In this example, the fan 23 can be arranged on the outside of the housing 21 and connected to the air inlet 213 of the fluid channel 215; in this example, the fan 23 can also be installed on the inside of the housing 21 and arranged at one end of the air flow channel near the air inlet 213. Since sewage will be generated during the water washing process of the water washing module 25, in this example, the fan 23 is arranged near the air inlet 213, so that the fan 23 can be as far away from the water washing module 25 as possible to reduce the impact of the water washing module 25 on the fan 23. The fan 23 in this example can be arranged between the adsorption module 24 and the air inlet 213.

[0082] Please refer to Figure 8 In some examples, the fan 23 is arranged in the fluid channel 215, and a guide plate 218 is arranged on the housing 21. The guide plate 218 is arranged in the fluid channel 215 between the fan 23 and the air inlet 213, and there is a gap between the guide plate 218 and the inner wall surface of the housing 21. In this example, the fan 23 is arranged close to the air inlet 213, and the guide plate 218 is arranged between the fan 23 and the air inlet 213. The guide plate 218 can be used to divert the airflow sucked in by the air inlet 213 so that the airflow flows in the direction of the fan 23 in a diffuse state. By changing the air volume and wind direction of the air intake of the fan 23, it can help reduce the air intake noise of the fan 23. Optionally, the air inlet 213 and the guide plate 218 in this example can be arranged on the same side of the housing 21, and optionally, the air inlet 213 and the guide plate 218 can be arranged on the second housing 212. In some examples, the guide plate 218 may be integrally provided with the second shell 212. The guide plate 218 may be a plate-like structure, a convex rib or a rib formed on the second shell 212.

[0083] Please refer to Fig. 9 In some examples, a grille 219 is provided on the housing 21, and at least one of the air inlet 213 and the air outlet 214 is provided with the grille 219. The grille 219 may be a plate-like structure or a convex rib that blocks the fluid channel 215. The grille 219 may separate the airflow to form a plurality of sub-channels along the extension direction of the fluid channel 215. The grille 219 may be used to divert the airflow to reduce the noise caused by uneven airflow. The grille 219 may be integrally provided with the corresponding part of the housing 21, or the grille 219 may be separately provided with the corresponding part of the housing 21 and connected to each other. In this example, the grille 219 may be provided at least one of the air inlet 213 and the air outlet 214 to guide the airflow at the air inlet 213 and / or the air outlet 214. In some examples, a grille 219 is provided at the air inlet 213, the fan 23 is disposed in the fluid channel 215 at one end close to the air inlet 213, and a guide plate 218 as described in any of the above examples is provided between the fan 23 and the air inlet 213, the grille 219 can extend to the guide plate 218, and the airflow of the sub-channels formed between adjacent grilles 219 can be diverted under the action of the guide plate 218, so that the airflow can be delivered to the fan 23 in a dispersed manner.

[0084] Please refer to Fig.10 and Fig.11 In some examples, a water inlet 254 is provided on the shell 21; the washing module 25 includes a water platform having a plurality of step portions 251, each of which has a step surface 252 facing the first shell 211, and the water inlet 254 is located on the side of the water platform away from the second shell 212.

[0085] The water inlet 254 may be a through hole penetrating the housing 21 , and may be used to connect the water inlet 30 , which may be a water pipe or a combination of a water pipe and a water pump. Water outside the housing 21 may enter the second chamber 217 through the water inlet 254 .

[0086] The water platform is arranged in the second chamber 217, and the water platform can be connected to the housing 21. A plurality of steps 251 are arranged on the water platform, and the plurality of steps 251 form a step-like structure of the water platform, and each step 251 can have a step surface 252 respectively, and the water inputted by the water inlet 254 in this example can flow toward the plurality of step surfaces 252. When the water flows toward the plurality of step surfaces 252, a plurality of water curtains can be formed in the second chamber 217, so that when the air flows through the second chamber 217, it is washed by the plurality of water curtains to improve the air purification efficiency. The plurality of step surfaces 252 are respectively facing the first housing 211. When the first housing 211 and the second housing 212 in this example are arranged up and down, the water is sprayed into the second chamber 217 from the step portion 251 toward one side of the first housing 211, and then flows toward the second housing 212, and the water flows to the plurality of step surfaces 252 to form a plurality of water curtains. Optionally, in this example, the first shell 211 can be located above the second shell 212, and water flows from top to bottom, and the water can be sprayed onto multiple step surfaces 252, or the water can gradually flow from the step surface 252 located at the upper part to the step surface 252 located at the lower part; Optionally, the first shell 211 can be located below the second shell 212, and water can be sprayed onto the step surface 252 from bottom to top; Optionally, the first shell 211 and the second shell 212 can be arranged left and right, and water can be sprayed onto the step surface 252 in the left and right direction. In this example, the step surface 252 can be arranged parallel to the inner surface of the first shell 211, and optionally, at least one step surface 252 is not arranged parallel to the inner surface of the first shell 211.

[0087] Please refer to Fig.11 In some examples, a plurality of step portions 251 are arranged from the first shell 211 to the second shell 212 ; and adjacent step portions 251 are spaced apart.

[0088] In this example, the multiple steps 251 are arranged at intervals from the first shell 211 to the second shell 212, so that a gap for gas flow can be formed between adjacent steps 251, and the airflow output from the first chamber 216 can flow along the gap between adjacent steps 251 toward the air outlet 214. In this example, the spacing and cross-sectional area of ​​the gap formed between adjacent steps 251 can be equal or unequal. When water flows along the multiple step surfaces 252 toward the air outlet 214, the gaps between adjacent steps 251 can form a space for water flow, so as to form multiple groups of water curtains between adjacent steps 251, thereby improving the air purification efficiency.

[0089] Please refer to Fig.10 and Fig.11 In some examples, a boss 253 is provided at one end of the step portion 251 close to the air outlet 214, and the boss 253 is provided to protrude toward the side of the corresponding step portion 251 away from the second shell 212. The boss 253 in this example can be a plate, a convex rib or a rib protruding from the end of the step portion 251 close to the air outlet 214, and the boss 253 can also be a bending structure formed by partially bending the step portion 251 toward one side of the second shell 212. The boss 253 can be a blocking structure formed on the side of the step surface 252 close to the air outlet 214, and the boss 253 can change the flow path of water on the step surface 252 to extend the residence time of water on the step portion 251, thereby improving the utilization rate of water. The number of bosses 253 in this example can be one, or the boss 253 can be provided on the step portion 251. In some examples, a section of the step portion 251 close to the partition 22 may also be provided with a boss 253 , so that the boss 253 blocks water from flowing from one end of the step portion 251 close to the partition 22 to the second chamber 217 .

[0090] In some examples, the water inlet 254 is disposed opposite to the step surface 252. In this example, the water inlet 254 can be sprayed directly toward the step surface 252 so that water can more fully form a water curtain and a water film on the step surface 252, which helps to improve water utilization.

[0091] In some examples, a baffle 2111 is provided on one side of the first housing 211 near the air outlet 214, and the end of the baffle 2111 facing away from the first housing 211 extends toward the second housing 212. The baffle 2111 can be used to prevent water from splashing in other directions. The baffle 2111 is provided on the first housing 211 to prevent the water input at the water inlet 254 from splashing at the air outlet 214, so that the water can flow to the step surface 252 as much as possible. Since the baffle 2111 can block the airflow path, the airflow can be turned at the baffle 2111, and the length of the flow path of the airflow in the housing 21 can be extended to extend the residence time of the airflow in the housing 21, so that the airflow can be more fully in contact with water, and the purification efficiency of the water washing module 25 on the airflow is improved. In some examples, the air outlet 214 is provided on the second housing 212, and the baffle 2111 can be suspended between the step surface 252 and the inner wall surface of the first housing 211. The baffle 2111 in this example can extend the residence time of the airflow in the housing 21 and improve the utilization rate of the water washing module 25. By improving the utilization rate of the water washing module 25, it is convenient to design the air purification device in a miniaturized manner and reduce the space occupancy rate of the air purification device on the smart toilet. Optionally, adjacent step portions 251 are arranged at intervals, and the baffle 2111 can be used to guide the airflow to the gap between adjacent step portions 251 to increase the contact area between the airflow and the water film formed by the step portions 251 and extend the contact time.

[0092] In some examples, a baffle 2111 is provided on one side of the first shell 211 close to the partition 22, and the baffle 2111 is located in the second chamber 217. The baffle 2111 can be used to form a shield at the part of the second chamber 217 close to the partition 22, so that the airflow can flow more to the step portion 251. The number of baffles 2111 in this example can be multiple, and the distances between the multiple baffles 2111 and the bottom wall of the second chamber 217 can be equal or unequal. In some examples, along the flow path of the gas, the distance between the multiple baffles 211 and the bottom wall of the second chamber 217 can be gradually reduced. On the one hand, the multiple baffles 211 can guide the airflow entering the second chamber 217 toward the bottom wall of the second chamber 217 to extend the flow path of the gas in the second chamber 217. On the other hand, the multiple baffles 211 can generate shielding at one end of the second chamber 217 close to the partition 22 to reduce the possibility of water droplets gathering on the first shell 211 and flowing into the first chamber 216.

[0093] In some examples, the first housing 211 is disposed above the second housing 212; the air outlet 214 is disposed in the second housing 212, and the air outlet 214 is disposed through the bottom wall of the second chamber 217. The baffle 2111 is connected to the first housing 211. Under the guiding action of the baffle 2111, water droplets can be directed along the surface of the baffle 2111 toward the second housing 212 to reduce the accumulation of water droplets on the first housing 211. Under the guidance of the baffle 2111, the gas can be directed toward the water washing module 25 so that more gas can be injected into the water curtain formed by the water washing module 25 to improve the purification efficiency of the gas. Since the baffle 2111 is connected to the first housing 211 and the air outlet 214 is disposed in the second housing 212, the baffle 2111 can be used to reduce the gas path area near the air outlet 214 in the second chamber 217 of the air flow to reduce the output efficiency of the air flow and further extend the contact time between the air flow and the water washing module 25. In some examples, the baffle 2111 and the water platform are at least partially overlapped in the projection of the baffle 2111 and the water platform on the bottom wall of the second chamber 217. In this example, when the projection is performed, the baffle 2111 partially overlaps with the water platform, and the baffle 2111 is spaced from the air outlet 214, so that the water flowing down from the baffle 2111 can drip onto the water platform, so as to reduce the water input from the water inlet 254 from being directly sprayed onto the water outlet, which helps to improve the utilization rate of water resources.

[0094] In some examples, another example of a water table is proposed, the water table includes a bracket 256 and a filter layer 257, and the filter layer 257 is wound around the bracket 256 to form a plurality of steps 251 on the bracket 256. The bracket 256 in this example can be used as a frame structure, and the filter layer 257 is wound around the bracket 256 so that the filter layer 257 is wound around the bracket 256 to form a step-like structure to form a step portion 251. The filter layer 257 can be a non-woven fabric or other layered structure with filtering performance. In this example, by using the bracket 256 to wind the filter layer 257 to form a step portion 251, the filter can be replaced when necessary to improve the service life of the air purification device 20. Optionally, in this example, the filter layer 257 can be manually wound around the bracket 256. In some examples, a reel and a drive structure for driving the reel can be set on the housing 21, and the reel is driven to rotate by the drive structure to achieve the reeling and replacement of the filter layer 257.

[0095] In some examples, the bracket 256 is detachably connected to at least one of the first shell 211 and the second shell 212. In this example, the bracket 256 can be mutually connected to the corresponding part of the shell 21 by snapping, plugging, pinning or screwing, the bracket 256 can be detachably connected to the first shell 211 or the second shell 212, and the shell 21 can also be connected to the first shell 211 and the second shell 212 at the same time.

[0098] The controller 130 may be a main control board of the smart toilet, or may be a control structure independent of the main control board of the smart toilet.

[0099] The detection device 120 can be used to detect whether a user uses the smart toilet, and can also be used to detect the user's usage time. The detection device 120 can be a detection method such as pressure detection, infrared detection, etc., or a combination of multiple detection methods.

[0100] The detection device 120 and the fan 23 are respectively connected to the controller 130 by electrical signals, which means that the detection device 120 and the fan 23 can respectively transmit electrical signals to the controller 130, and the electrical signal transmission can be level signal transmission.
