[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] With the continuous development of science and technology, cleaning equipment such as floor scrubbers and robot vacuum cleaners are increasingly entering people's daily lives. These cleaning devices are typically equipped with a wastewater tank, which collects solid, liquid, or solid-liquid mixtures of waste during cleaning operations.

[0022] In existing technologies, after long-term use, bacteria can easily grow in the sewage collection chamber of the sewage tank, producing a lot of odor, which will bring a poor user experience.

[0023] This application first proposes a sewage tank, such as Figures 1 to 8 As shown. This wastewater tank is used for cleaning equipment; see reference. Figure 1 , Figure 2The wastewater tank includes a tank assembly 11 and a sterilization assembly 12. The tank assembly 11 forms a sludge collection chamber 10, a sludge inlet 20, and a sludge collection channel 30. The sludge collection chamber 10 and the sludge collection channel 30 are connected through the sludge inlet 20. Fluid enters the sludge collection chamber 10 through the sludge collection channel 30 and the sludge inlet 20 in sequence. The sterilization assembly 12 is disposed in the sludge collection chamber 10 and is located downstream of the sludge inlet 20.

[0024] Wastewater tanks can store waste collected by cleaning equipment during the cleaning process through methods such as suction; the physical state of the waste is not limited, for example, it can be solid, liquid or solid-liquid mixture.

[0025] Waste can enter the collection chamber 10 in fluid form through the collection channel 30 and the inlet 20 to achieve waste collection. In some embodiments, cleaning fluid and clean water can also enter the collection chamber 10 through the collection channel 30 and the inlet 20 to achieve cleaning. In some embodiments, hot air can also enter the collection chamber 10 in fluid form through the collection channel 30 and the inlet 20 to dry the entire waste collection channel. In some application scenarios, the waste collection chamber 10 of the wastewater tank can be emptied, cleaned, and dried periodically by manual or automatic methods.

[0026] Among them, the sterilization component 12 can sterilize and suppress odors, and improve the hygiene of the sludge collection chamber 10.

[0027] When the cleaning equipment performs a cleaning task, the machine body has at least three cleaning states: upright, horizontal, and inclined. This allows the equipment to clean different areas. The wastewater tank also exists in these three states depending on the cleaning status of the machine body.

[0028] In the above manner, the sterilization component 12 is installed in the sludge collection chamber 10 and is located downstream of the sludge inlet 20. The sludge, cleaning fluid, hot air and other fluids flowing out of the sludge inlet 20 can flow through the sterilization component 12. The sterilization component 12 can sterilize the sludge, cleaning fluid, hot air and other fluids flowing through it, thereby eliminating odors from the sludge collection chamber 10 and improving the user experience.

[0029] Furthermore, the sewage collection channel 30 allows sewage and other fluids to flow through the sewage collection channel 30 to the sewage inlet 20, facilitating centralized treatment and transportation of the fluids.

[0030] In some embodiments (not shown), the inlet 20 and the sterilization component 12 are located on the same inner wall of the collection chamber 10.

[0031] The inlet 20 is located on the inner wall of the collection chamber 10, allowing fluids such as dirt to flow into the collection chamber 10 through the inner wall. The sterilization component 12 is located on the same inner wall as the inlet 20. The inner wall can guide the flow, allowing fluids such as dirt to flow through the sterilization component 12, thereby improving the sterilization effect.

[0032] In some embodiments (not shown), when the sewage tank is upright, the sludge collection chamber 10 has a first end and a second end arranged vertically opposite each other, with the first end located above the second end; the sludge inlet 20 of the sludge collection chamber 10 is located at the first end and faces the second end. This arrangement allows fluids such as sludge to flow from the first end to the second end under the action of gravity, making the flow direction of the fluid more concentrated. Therefore, it is convenient to position the sterilization component 12, allowing more fluid to directly contact the sterilization component 12.

[0033] In some embodiments, see Figure 2 , Figure 3 In the upright position of the sewage tank, the sludge collection chamber 10 has a first end and a second end arranged vertically opposite each other, with the first end located above the second end; the sludge inlet 20 of the sludge collection chamber 10 is located on the inner wall near the first end. This arrangement allows fluids such as sewage to flow out of the sludge inlet 20 and then flow in a direction from the first end to the second end under the action of gravity. This makes the flow direction of the fluid after flowing out of the sludge inlet 20 and into the sludge collection chamber 10 more concentrated, thus facilitating the placement of the sterilization component 12 and allowing more fluid to directly contact the sterilization component 12.

[0034] In some embodiments, see Figures 1 to 3 The sterilization component 12 is located above the full water level of the sludge collection chamber 10.

[0035] The sludge collection chamber 10 is equipped with a full water level to remind users to clean the sludge collection chamber 10 in a timely manner and prevent the risk of sludge overflow due to excessive sludge in the sludge collection chamber 10.

[0036] By positioning the sterilization component 12 above the full water level of the sludge collection chamber 10, the risk of the sterilization component 12 being soaked in sludge within the sludge collection chamber 10 for an extended period can be reduced, thereby improving the service life and reliability of the sterilization component 12.

[0037] In some embodiments, see Figures 1 to 3 The wastewater tank also includes a detection component 13, which is located at the full water level of the wastewater collection chamber 10.

[0038] The detection component 13 can be a detection electrode, a float level sensor, a photoelectric level sensor, an ultrasonic level sensor, etc. The contents of the collection chamber 10 can be solid, liquid, or a solid-liquid mixture. When the accumulated dirt, cleaning fluid, and other contents in the collection chamber 10 reach the full water level, the detection component 13 will generate a trigger signal to realize the full water indication function.

[0039] In some embodiments, when the liquid level in the collection chamber 10 reaches the full water level, the detection component 13 will issue a reminder signal to enable the cleaning equipment to automatically move to a designated position to discharge the contents of the sewage tank, or to remind the user to manually discharge the sewage in the collection chamber 10 in a timely manner.

[0040] In some embodiments, the detection component 13 can detect the water level in each cleaning posture of the cleaning equipment, which is beneficial to ensure that the sewage and other contents in the collection chamber 10 do not flow back to the surface to be cleaned through the inlet 20 and the collection channel in each cleaning posture.

[0041] In some embodiments, the detection component 13 includes a float that floats up when the sewage in the sewage tank reaches the full water level, preventing sewage from continuing to enter the collection chamber 10. In some embodiments, the sewage tank also includes a sludge inlet cover 15, which is linked to the detection component 13. When the float floats up, it causes the sludge inlet cover 15 to close on the sludge inlet 20, thereby preventing sewage from continuing to enter the collection chamber 10.

[0042] In some embodiments, see Figures 6 to 8 The sterilization component 12 includes a box body 121 and a cover plate 122. The box body 121 forms a receiving cavity; the cover plate 122 is used to cover the opening of the receiving cavity; both the box body 121 and the cover plate 122 have openings 40 that communicate with the receiving cavity; and a sterilizing agent is placed inside the receiving cavity.

[0043] The sterilization component 12 includes a housing 121 and a cover 122. The cover 122 can be closed and opened to allow for the filling or replacement of sterilizing agents into the receiving cavity, improving ease of use. Both the housing 121 and the cover 122 have openings 40 communicating with the receiving cavity, creating a flow-through structure. This allows fluid flowing through the sterilization component 12 to enter and exit the receiving cavity through these openings 40, enabling direct contact between the fluid and the sterilizing agent within the cavity. This achieves sterilization and odor removal of the fluid by the sterilizing agent and reduces the risk of the sterilization component 12 being submerged in sewage or other liquids for extended periods, thus extending the service life of the sterilizing agent. This design also helps reduce the obstruction of fluid flow by the sterilization component 12. Furthermore, this design is simple in structure and reliable in performance.

[0044] In other embodiments, the sterilization component 12 may include a sterilizing agent and a mesh bag, with the sterilizing agent disposed inside the mesh bag. The mesh bag can be formed from a nylon filter or other filter material, and its structure is simple and readily available.

[0045] In some embodiments, the cover plate 122 and the box body 121 are detachably configured to facilitate filling the box body 121 with sterilizing agents.

[0046] In some embodiments, see Figure 8 The opening of the receiving cavity is located on the bottom wall 1211 of the box body 121 opposite to the sewage inlet 20. The cover plate 122 is used to cover the opening, so the cover plate 122 is located on the bottom wall 1211 of the box body 121 opposite to the sewage inlet 20. The opening 40 on the box body 121 serves as a water inlet, and the opening 40 on the cover plate 122 serves as a water outlet.

[0047] The bottom wall 1211 of the casing 121 refers to the lowest wall of the casing 121 when the sewage tank is upright. This bottom wall 1211 is located downstream of the sewage inlet 20. Fluid enters the collection chamber 10 through the sewage inlet 20, first reaching the other walls of the casing 121, and finally reaching the bottom wall 1211. Therefore, in one application scenario, the opening 40 on the casing 121 serves as a water inlet, and the opening 40 on the cover plate 122 covering the opening on the bottom wall 1211 serves as a water outlet. Fluid enters the receiving chamber through the water inlet and flows out of the receiving chamber through the water outlet.

[0048] In some embodiments, the antibacterial agent includes a porous solid-state sustained-release functional unit.

[0049] The porous solid slow-release functional unit can utilize its porous nature to fully contact the fluid, thereby improving the sterilization effect of the sterilizing agent on the fluid. Furthermore, the porous solid slow-release functional unit has a solid slow-release function, which can effectively improve the service life and reliability of the sterilizing agent. For example, the porous solid slow-release functional unit includes multiple cylindrical or cuboid strip-shaped slow-release units to achieve full contact with fluids such as sewage and hot air, thereby achieving a long-lasting sterilization effect.

[0050] In one application scenario, the porous solid slow-release functional unit can dissolve and release functional substances into fluids such as sewage to achieve sterilization.

[0051] In some embodiments, the porous solid-state sustained-release functional unit includes at least one of silver ion sustained-release particles, chlorine dioxide sustained-release particles, guanidine salt sustained-release particles, etc.

[0052] In some embodiments, the disinfectant also includes other loosely structured solid-state sustained-release functional units.

[0053] In some embodiments, see Figure 1The housing assembly 11 includes a first housing 111 and a second housing 112; see reference. Figures 2 to 3 The first housing 111 forms a dirt collection chamber 10 and a dirt collection channel 30; see reference Figures 3 to 5 The second housing 112 extends toward the first housing 111 and is provided with a baffle plate 14. The sewage inlet 20 and the sterilization component 12 are provided on the baffle plate 14. When the second housing 112 is closed with the first housing 111, the sewage collection channel 30 is connected to the sewage collection chamber 10 through the sewage inlet 20, and the baffle plate 14 is at least partially located in the sewage collection chamber 10.

[0054] When the first housing 111 and the second housing 112 are closed, sewage and other fluids can reach the inlet 20 through the collection channel 30 and then enter the collection chamber 10. Since the baffle plate 14 is located inside the collection chamber 10 after the first housing 111 and the second housing 112 are closed, and the inlet 20 is located on the baffle plate 14, the baffle plate 14 can guide the sewage and other fluids flowing out of the inlet 20. After the fluid flows out of the inlet 20, it can quickly flow through the sterilization component 12 on the baffle plate 14 to achieve sterilization. Therefore, this arrangement can improve sterilization efficiency and effect.

[0055] In one application scenario, the baffle 14 includes a sewage inlet area and a guide area with a sewage inlet 20. The sewage inlet area abuts against the first housing 111 to guide the sewage collection channel 30 and the sewage inlet 20. For example, see Figures 4 to 5 The sewage inlet area includes a sewage inlet pipe 16, the inlet of which is connected to the outlet of the sewage collection channel 30, and the sewage inlet 20 is set as the outlet of the sewage inlet pipe 16.

[0056] In some embodiments, the first housing 111 is used as the body of the sewage tank, and the second housing 112 is used as the cover of the sewage tank. A locking mechanism may also be provided on the cover to enable the loading and unloading of the sewage tank from the body of the cleaning equipment.

[0057] In some embodiments, see Figures 2 to 3 The sludge collection chamber 10 forms a first sidewall 100 and a second sidewall 200 that are arranged opposite to each other, and the sludge inlet 20 is disposed on the first sidewall 100; the baffle plate 14 forms a first guide section 141 downstream of the sludge inlet 20, the first guide section 141 extends obliquely towards the second sidewall 200 in the direction toward the bottom wall 300 of the sludge collection chamber 10, and the sterilization component 12 is disposed at the end of the first guide section 141 away from the sludge inlet 20.

[0058] It should be noted that the bottom wall 300 of the sludge collection chamber 10 refers to the bottommost wall of the sludge tank when it is in an upright position.

[0059] When the sewage tank is in an upright position, the sewage inlet 20 is located close to the top wall of the sewage collection chamber 10.

[0060] The first guide section 141 can improve the guiding effect of the baffle plate 14. Specifically, the first guide section 141 extends towards the bottom wall 300 of the sludge collection chamber 10 and is inclined towards the direction close to the second side wall 200. Since the sludge inlet 20 faces the second side wall 200, the fluid flowing out of the sludge inlet 20 will normally have a velocity component in the direction from the first side wall 100 to the second side wall 200. Setting the first guide section 141 to be inclined towards the direction close to the second side wall 200 helps to make the first guide section 141 conform to the flow trajectory of the fluid and improve the guiding effect of the first guide section 141 on the fluid.

[0061] Furthermore, the sterilization component 12 is disposed at the end of the first guide section 141 away from the sewage inlet 20, which allows the fluid left on the first guide section 141 to be guided to the sterilization component 12, so that the fluid can fully contact the sterilization component 12 and improve the sterilization effect.

[0062] In some embodiments, see Figures 3 to 5 The first guide section 141 forms an installation section 142 at one end away from the sewage inlet 20. The installation section 142 extends toward the bottom wall 300 of the sewage collection chamber 10 and is inclined toward the direction close to the first side wall 100. The sterilization component 12 is attached to the side of the installation section 142 close to the second side wall 200.

[0063] The mounting part 142 can improve the positional stability of the sterilization component 12. The mounting part 142 is attached to the sterilization component 12, which can increase the contact area between the mounting part 142 and the sterilization component 12 and improve the fixing effect of the sterilization component 12.

[0064] The mounting portion 142 is inclined towards the first sidewall 100, and the first flow guide portion 141 is inclined towards the second sidewall 200. The inclination direction of the mounting portion 142 is opposite to that of the first flow guide portion 141, which can form a clearance space on the side of the mounting portion 142 near the second sidewall 200. When the sterilization component 12 is placed on the side of the mounting portion 142 near the second sidewall 200, the sterilization component 12 can be placed within this clearance space, so that the sterilization component 12 is located as close as possible to the flow path of the fluid, thereby increasing the contact area between the fluid and the sterilization component 12 and improving the sterilization effect.

[0065] In some embodiments, see Figures 2 to 5 The baffle plate 14 includes a sewage inlet area and a flow guide area with a sewage inlet 20. The sewage inlet area abuts against the first housing 111 to guide the sewage collection channel 30 and the sewage inlet 20. The flow guide area at least partially surrounds the sewage inlet area to achieve the flow guide effect.

[0066] For example, see Figures 3 to 5The flow guiding area includes the first flow guiding part 141 mentioned above; the flow guiding area also includes a second flow guiding part 143 disposed on both sides of the first flow guiding part 141 and the sewage inlet area, and extending in the direction from the first side wall 100 to the second side wall 200.

[0067] For example, the detection component 13 is disposed on the side of the second flow guide 143 opposite to the inlet 20. This arrangement can reduce the interference of the fluid flowing out of the inlet 20 on the detection component 13 when splashing.

[0068] In some embodiments, see Figures 3 to 5 The baffle plate 14 also includes a third guide portion 144, which is disposed at the end of the mounting portion 142 away from the first guide portion 141 and extends toward the bottom wall 300 of the sludge collection chamber 10.

[0069] The third flow guide 144 can guide the fluid flowing through the mounting part 142 to the bottom wall 300 of the collection chamber 10, thereby reducing the risk of sewage and other fluids splashing everywhere in the collection chamber 10. In some applications, the sterilization component 12 is fitted to the side of the third flow guide 144 closest to the second side wall 200, which can further increase the contact area between the sterilization component 12 and the baffle 14 and improve the positional stability of the sterilization component 12.

[0070] In some embodiments, see Figures 6 to 7 The sterilization component 12 includes a first latching part 123 and a triggering part 124, with the triggering part 124 connected to the first latching part 123. The sterilization component 12 is fixed in the dirt collection chamber 10 through the first latching part 123. When the triggering part 124 is triggered, the first latching part 123 enters a released state so that the sterilization component 12 is separated from the housing component 11.

[0071] By triggering the trigger part 124, the locking of the first locking part 123 is released, thereby enabling the disassembly of the sterilization component 12.

[0072] In some embodiments, the trigger portion 124 includes an elastic element. For example, pressing the trigger portion 124 causes it to displace, thereby moving the first latching portion 123 and releasing the latching state.

[0073] In some embodiments, see Figure 4 , Figure 6 A snap-fit ​​groove 1121 is formed on the third flow guide 144. The first snap-fit ​​part 123 includes a protrusion 1231, which snaps into the snap-fit ​​groove 1121 to fix the sterilization component 12 on the third flow guide 144.

[0074] In some embodiments, the first latching part 123 is disposed on the housing 121 of the sterilization assembly 12, and the housing 121 is fixed in the dirt collection chamber 10 by the first latching part 123. When the triggering part 124 is triggered, the first latching part 123 enters the released state, causing the housing 121 to separate from the box assembly 11.

[0075] Since the cover plate 122 is placed over the opening of the box body 121, the first snap-fit ​​part 123 is positioned on the box body 121 in this way, which can improve the positional stability of the first snap-fit ​​part 123.

[0076] In some embodiments, the wastewater tank further includes a baffle plate 14 extending toward the bottom wall 300 of the collection chamber 10 on the tank assembly 11. The baffle plate 14 is at least partially disposed within the collection chamber 10, and the inlet 20 is disposed on the baffle plate 14. A first snap-fit ​​portion 123 is disposed on a first sub-side wall 1212 of the housing 121 near the baffle plate 14. The first sub-side wall 1212 can be attached to the downstream of the inlet 20 on the baffle plate 14 via the first snap-fit ​​portion 123. The water inlet of the sterilization component 12 is disposed on a second sub-side wall 1213 opposite to the first sub-side wall 1212.

[0077] Specifically, the first snap-fit ​​portion 123 is positioned near the first sub-side wall 1212 of the baffle plate 14, which helps to reduce the distance between the first snap-fit ​​portion 123 and the baffle plate 14. The connection between the first snap-fit ​​portion 123 and the baffle plate 14 fixes the position of the box body 121, allowing the first sub-side wall 1212 to be attached to the downstream of the baffle plate 14. This increases the contact area between the box body 121 and the baffle plate 14, improves the positional stability of the box body 121, and enhances the overall structural compactness. Furthermore, by fixing the box body 121 downstream of the sewage inlet 20 in the above manner, it facilitates fluid flow through the sterilization component 12. Furthermore, by setting the water inlet hole on the second sub-side wall 1213 opposite to the first sub-side wall 1212 in the above manner, the water inlet hole can be located on the side of the housing 121 away from the baffle plate 14. Therefore, fluid can flow into the sterilization component 12 through the water inlet hole on the second sub-side wall 1213. This method can reduce the obstruction of the water inlet hole of the sterilization component 12 by the baffle plate 14 and improve the water flow efficiency of the sterilization component 12.

[0078] In some embodiments, see Figure 2 , Figure 3 , Figure 8 The top wall 1214 of the box body 121 is attached to the side of the mounting part 142 near the second side wall 200, and the tilt direction of the top wall 1214 is the same as the tilt direction of the mounting part 142; the first sub-side wall 1212 of the box body 121 is attached to the side of the third guide part 144 near the second side wall 200.

[0079] The top wall 1214 of the box 121 refers to the topmost wall of the box 121 when the sewage tank is in an upright state.

[0080] The box body 121 has at least two walls that are attached to the baffle plate 14, which improves the compactness of the overall structure. At least the first sub-side wall 1212 can be attached to the third flow guide 144 via the first snap-fit ​​part 123, which improves the positional stability of the box body 121. Furthermore, through the above method, the box body 121 can be fixed in the clearance space downstream of the baffle plate 14, reducing the problem of instability caused by direct fluid impact on the top wall 1214 of the box body 121. Also, through the above method, the box body 121 can be located at the lower end of the first flow guide 141 away from the sewage inlet 20, allowing as much fluid as possible to flow into the sterilization assembly 12 through the water inlet hole on the second sub-side wall 1213 of the box body 121.

[0081] In some embodiments, see Figure 6 , Figure 7 The first snap-fit ​​part 123 also includes a clip 1232. Pressing the trigger part 124 can drive the clip 1232 to move. When the trigger part 124 is released, the clip 1232 is reset and can clamp the third guide part 144 together with the wall of the box body 121 to fix the position of the sterilization component 12.

[0082] In some embodiments, the first snap-fit ​​portion 123 includes a protrusion 1231 and a clip 1232, which can improve snap-fit ​​stability and improve the positional stability of the sterilization component 12.

[0083] In some embodiments, see Figure 6 , Figure 7 The sterilization component 12 includes a housing 121, a first snap-fit ​​part 123 elastically connected to the housing 121, and a trigger part 124 connected to the movable end of the first snap-fit ​​part 123. Pressing the trigger part 124 causes the movable end of the first snap-fit ​​part 123 to move relative to the housing 121, thereby releasing the snap-fit ​​and removing the sterilization component 12 from the dirt collection chamber 10.

[0084] In some embodiments, the first snap-fit ​​portion 123, the trigger portion 124, and the housing 121 are integrally formed.

[0085] In other embodiments, the sterilization component can also be fixedly connected to the mounting portion 142 or the first flow guide portion 141 in the manner described above.

[0086] In other embodiments, the sterilization component 12 can be fixed in the dirt collection chamber 10 in a similar manner. For example, a second snap-fit ​​part in the form of a snap-fit ​​groove 1121 can be formed on the inner side wall of the dirt collection chamber 10 to achieve snap-fit ​​engagement with the first snap-fit ​​part 123.

[0087] In other embodiments, the sterilization component 12 can be fixed on the bottom wall 300 of the sludge collection chamber 10 or on the inner side wall near the bottom wall 300 to sterilize the contents of the sludge collection chamber 10.

[0088] In some embodiments, the detection component 13 and the sterilization component 12 are both disposed on the second housing 112.

[0089] This application further proposes a cleaning device, such as Figures 1 to 7 As shown. The cleaning equipment includes a main body and a wastewater tank as described in any of the above embodiments, which is detachably mounted on the main body.

[0090] The specific implementation method and working principle of the sewage tank can be found in the above embodiments, and will not be repeated here. The sewage tank is detachably installed on the machine body for easy cleaning and maintenance by the user.

[0091] In this way, the sterilization component 12 is installed in the sludge collection chamber 10 and is located downstream of the sludge inlet 20. The sludge, cleaning fluid, hot air and other fluids flowing out of the sludge inlet 20 can flow through the sterilization component 12. The sterilization component 12 can sterilize the sludge, cleaning fluid, hot air and other fluids flowing through it, so as to reduce the odor in the sludge collection chamber 10 and improve the user experience.

[0092] In some embodiments, the cleaning device further includes a cleaning module and a main body. The main body is rotatably mounted on the cleaning module, and the wastewater tank is detachably mounted on the main body. The cleaning module is located at the lower end of the main body and is typically used to move over the surface to be cleaned for cleaning. The main body can rotate relative to the cleaning module to adapt to different cleaning scenarios, such as cleaning hard-to-reach areas like under beds and sofas, where the main body needs to be laid flat. Therefore, by rotating the main body relative to the cleaning module, the cleaning device has at least three states: an upright cleaning state, a flat cleaning state, and a tilted cleaning state (between the upright and flat states), facilitating the cleaning of different areas. As the main body rotates, the wastewater tank has three states: upright, flat, and tilted.

[0093] The cleaning equipment can be a floor scrubber or other cleaning equipment containing a wastewater tank. Specifically, the cleaning module can be a floor brush module. For example, when the dirty water from the floor scrubber cleans the floor, it enters the wastewater tank through the collection channel 30 and the inlet 20, so that the wastewater generated after cleaning is recycled into the wastewater tank.

[0094] Unlike existing technologies, the wastewater tank of this application is used in cleaning equipment and includes a tank assembly and a sterilization assembly. The tank assembly forms a wastewater collection chamber, a wastewater inlet, and a wastewater collection channel. The wastewater collection chamber and the wastewater collection channel are connected through the wastewater inlet, and fluid sequentially enters the wastewater collection chamber through the wastewater collection channel and the wastewater inlet. The sterilization assembly is located inside the wastewater collection chamber and downstream of the wastewater inlet. The sterilization assembly is positioned above the full water level in the wastewater collection chamber. Through this method, the sterilization assembly, located inside the wastewater collection chamber and downstream of the wastewater inlet, allows waste, cleaning fluid, hot air, and other fluids flowing from the wastewater inlet to pass through the sterilization assembly. The sterilization assembly sterilizes the flowing waste, cleaning fluid, hot air, and other fluids, thereby reducing odors in the wastewater collection chamber and improving the user experience.

[0095] It is worth noting that the accompanying drawings are only for illustrating the structural and connection relationships of the product in this application, and do not limit the specific structural dimensions of the product in this application.

[0096] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
