Description

Technical Field

[0001] This invention relates to the field of intelligent cleaning equipment technology, specifically to a liquid replenishment sealing device, a cleaning base station having the liquid replenishment sealing device, a cleaning system, and a control method for the cleaning system. Background Technology

[0002] As people's demands for smart homes increase, various types of smart cleaning devices have emerged on the market, such as robotic vacuum cleaners and floor scrubbers. These smart cleaning devices are usually equipped with cleaning base stations, which can clean the cleaning devices and collect the waste they produce.

[0003] When cleaning base stations are used to collect waste from cleaning equipment, some of the waste may be wet waste. Wet waste is more prone to bacterial growth than dry waste, and waste is usually not allowed to be stored in the waste storage device of the cleaning base station for too long. This results in users having to frequently clean the waste storage device, which puts a burden on users.

[0004] In existing technologies, to prevent bacterial growth in trash within base station cleaning facilities and reduce maintenance frequency, the trash needs to be dried. During the drying process, airflow generating devices (such as fans) are sometimes used to remove moisture generated during drying, thereby improving efficiency. However, the airflow passing through the trash may contain odors or bacteria, which could negatively impact the user experience if it enters the room. To prevent the spread of odors or bacteria, the airflow path needs to be sealed to ensure direct discharge into a floor drain, preventing odors or bacteria from leaking into the room. However, in practical applications, it has been found that even after drying is complete, a noticeable odor may still be present, resulting in a poor user experience. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, a cleaning base station is provided according to a first aspect of this application. The cleaning base station includes: a discharge channel for discharging gaseous emissions and supplying liquid to a floor drain; an execution component connected to the discharge channel for controlling the liquid supply; and a control component for driving the execution component to supply liquid to the floor drain after the gaseous emissions have been discharged, thereby establishing a liquid seal in a sewer pipe connected to the floor drain.

[0006] For example, the control component drives the execution component to supply liquid to the floor drain, including performing the following operations: controlling the execution component to turn on and supply a preset amount of liquid to the floor drain.

[0007] For example, the control component controls the execution component to turn on and supply a preset amount of liquid to the floor drain, including performing the following operations: controlling the execution component to turn on and starting a timer from the moment the execution component turns on; when the timer reaches a preset time, controlling the execution component to turn off, so that the preset amount of liquid is supplied to the floor drain; or

[0008] The cleaning base station also includes a flow detector for detecting the supply flow of liquid, and a control component controls the execution component to turn on and supply a preset amount of liquid to the drain, including performing the following operations: controlling the execution component to turn on and determining the total supply of liquid based on the supply flow; when the total supply reaches the preset amount, controlling the execution component to turn off.

[0009] For example, the discharge channel includes a sludge discharge channel for discharging gaseous emissions and a liquid replenishment channel for supplying liquids.

[0010] For example, the clean base station includes a base station body and a connector assembly connected to the base station body, the connector assembly including:

[0011] The system includes a drain channel and a first connector. The drain channel connects the drain outlet of the base station body and the first connector. The first connector is connected to a drain pipe for connecting to a floor drain. The drain channel comprises the drain channel, the first connector, and the drain pipe.

[0012] The connector includes a liquid seal channel and a second connector. The inlet of the liquid seal channel is used to connect to a water source for supplying liquid. The second connector is located at the outlet of the liquid seal channel and is connected to a seal pipe for connecting to a floor drain. The liquid seal channel includes the connector liquid seal channel, the second connector, and the seal pipe.

[0013] For example, the first connector and the second connector face the same side.

[0014] For example, the inner diameter of the drain pipe is larger than the inner diameter of the seal pipe.

[0015] For example, the connector assembly includes: an adapter base, a first connector and a second connector disposed on the adapter base, the adapter base being configured to be rotatably and / or detachably mounted to the base station body to change the orientation of the first connector and the second connector.

[0016] For example, the adapter has a first working position and a second working position relative to the base station body; when the adapter is in the first working position, the first connector and the second connector face a first direction; and when the adapter is in the second working position, the first connector and the second connector face a second direction different from the first direction.

[0017] For example, the adapter is provided with a first central channel and a first peripheral channel located around the first central channel. The first central channel forms part of one of the connector drain channel and the connector liquid seal channel, and the first peripheral channel forms part of the other of the connector drain channel and the connector liquid seal channel.

[0018] For example, the connector assembly also includes a drain rack disposed on the base station body, the drain rack having a second central channel and a second peripheral channel disposed around the second central channel, the first central channel and the second central channel being connected to form one of the connector drain channel and the connector liquid seal channel; and the first peripheral channel and the second peripheral channel being connected to form the other of the connector drain channel and the connector liquid seal channel.

[0019] For example, the adapter includes a bend forming a first central channel and a first outer tube surrounding the bend, with a first peripheral channel formed between the bend and the first outer tube. The drain rack includes a straight tube forming a second central channel and a second outer tube surrounding the straight tube, with a second peripheral channel formed between the straight tube and the second outer tube. The straight tube is sealed to the bend, and the second outer tube is sealed to the first outer tube.

[0020] For example, when the first peripheral channel and the second peripheral channel form a joint liquid seal channel, the outer side of the second outer tube is provided with a third connector for communicating with the water source supplying the liquid, and the third connector is connected to the second peripheral channel.

[0021] For example, the first connector, the second connector, and / or the third connector are perpendicular to the straight pipe.

[0022] For example, the third connector is located inside the base station body, and the third connector is connected to a water supply pipe located inside the base station body, the water supply pipe being used to connect to a water source.

[0023] For example, the adapter is detachably connected to the drain rack via a snap-fit.

[0024] For example, the drain rack is provided with a limiting part that protrudes outward toward the base station body, the adapter is inserted into the space surrounded by the limiting part, the limiting part is provided with a buckle adapter part, and the buckle engages with the buckle adapter part.

[0025] For example, the floor drain has a first floor drain channel, a second floor drain channel and a discharge channel. The inlet of the first floor drain channel and the inlet of the second floor drain channel are respectively connected to the outlet of the sewage discharge channel and the outlet of the liquid replenishment channel. The outlet of the first floor drain channel and the outlet of the second floor drain channel are connected to the discharge channel.

[0026] For example, the floor drain includes a third floor drain channel and a discharge channel, one end of the third floor drain channel being connected to the external environment and the other end being connected to the discharge channel.

[0027] For example, a backflow preventer is provided in the third drain channel to prevent gas and / or liquid in the discharge channel from leaking into the external environment.

[0028] For example, the execution components include: a pumping device disposed within the cleaning base station, with the inlet of the discharge channel connected to the pumping device; or a control valve, the inlet of which is connected to a municipal water source or a water source within the cleaning base station, and the outlet of which is connected to the inlet of the discharge channel.

[0029] For example, the floor drain has a fourth floor drain channel and a discharge channel, the inlet of the fourth floor drain channel and the discharge channel are connected, and the outlet of the fourth floor drain channel is connected to the discharge channel.

[0030] For example, the clean base station also includes a base station body, which is equipped with a waste storage device and a drying device. The drying device is used to dry the waste stored in the waste storage device and generate gas emissions.

[0031] For example, the discharge channel includes a sludge discharge channel for discharging gaseous emissions and a liquid replenishment channel for supplying liquids, wherein: the outlet of the liquid replenishment channel converges to the sludge discharge channel, and the inlet of the sludge discharge channel is connected to the outlet of the waste storage device; or the liquid replenishment channel and the sludge discharge channel are not interconnected.

[0032] According to a second aspect of this application, a liquid seal device is provided, which is applied to a clean base station. The clean base station includes a sewage discharge channel for communicating with a floor drain to discharge at least gaseous emissions into the floor drain; the liquid seal device includes: a liquid seal channel for communicating with the floor drain to supply liquid to the floor drain; an actuation component for controlling the supply of liquid; and a control component for driving the actuation component to supply liquid to the floor drain after the gaseous emissions have been discharged, so as to establish a liquid seal in the sewer pipe connected to the floor drain.

[0033] According to a third aspect of this application, a cleaning system is provided, including a cleaning device and any of the cleaning base stations described above, or including a cleaning device, a cleaning base station, and a liquid sealing device; the cleaning device may optionally interface with the cleaning base station.

[0034] For example, the cleaning equipment includes a dust collection container, and when the cleaning equipment is docked with a cleaning base station, the outlet of the dust collection container is connected to an exhaust channel.

[0035] According to a fourth aspect of this application, a control method for a cleaning base station is provided, comprising: a drying step: drying the waste stored in the waste storage device of the cleaning base station of the cleaning system, and discharging the gas emissions generated during the drying process into a floor drain; and a sealing step: supplying liquid to the floor drain after the drying step is completed to establish a liquid seal in the floor drain.

[0036] For example, the sealing step includes supplying a preset amount of liquid to the drain.

[0037] For example, the resealing step specifically includes: starting a timer from the moment liquid is supplied to the drain; stopping the liquid supply when the timer reaches a preset time, so that a preset amount of liquid is supplied to the drain; or detecting the liquid supply flow rate; determining the total amount of liquid supplied based on the supply flow rate; and stopping the liquid supply when the total amount of liquid supplied reaches a preset amount.

[0038] For example, the control method further includes a filtration step prior to the drying step: receiving dirt from the cleaning equipment and filtering out wet waste from the dirt to discharge wastewater into a floor drain.

[0039] For example, the drying step specifically includes using a fan to dry solid waste to generate gaseous emissions.

[0040] In the clean base station provided in this application, after the gaseous emissions are discharged, the control component can drive the execution component to supply liquid from the discharge channel to the floor drain to re-establish a liquid seal in the sewer pipe connected to the floor drain, thereby compensating for the portion of liquid used to establish the liquid seal in the sewer pipe that was flushed away during the gaseous emissions process. This ensures that the gaseous emissions from the clean base station are not affected, while also re-establishing the liquid seal in the sewer pipe, preventing undesirable odors and / or bacteria in the sewer pipe from spreading into the indoor environment.

This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0060] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0061] According to a first aspect of the present invention, a cleaning base station 100 is provided, which is used in cleaning equipment 200 such as a sweeping robot, a mopping robot, a floor scrubber, etc. Figure 1 As shown. The cleaning device 200 can optionally dock with the cleaning base station 100. After completing its daily cleaning tasks, the cleaning device 200 can automatically return or be moved by the user to the cleaning base station 100 to dock with it. The cleaning base station 100 can charge the cleaning device 200. Optionally, the dirt collected by the cleaning device 200 in its dust collection container (e.g., dust box, dust bag, wastewater tank, etc.) during daily cleaning can be discharged into the waste storage device 120 of the cleaning base station 100.

[0062] The types of waste collected by different cleaning equipment vary. The waste is usually solid waste or a mixture of solid and liquid waste (including wet solid waste and sewage).

[0063] For the cleaning equipment 200, which handles solid waste, the waste storage device 120 of the cleaning base station 100 has a larger capacity than the dust collection container 210 of the cleaning equipment 200. This allows it to store the waste collected during several daily cleaning cycles until the waste storage device 120 is full, at which point the user can empty it. This reduces the frequency of maintenance required by the user for the cleaning base station 100.

[0064] For the cleaning equipment 200, which handles a mixture of solid and liquid waste, the capacity of the waste storage device 120 of the cleaning base station 100 is greater than the capacity of the dust collection container 210 of the cleaning equipment 200. This allows the equipment to store the waste collected during several daily cleaning sessions until the waste storage device 120 is full of the solid-liquid mixture. The user then cleans the waste storage device 120, which reduces the frequency of maintenance required by the user. In this case, the waste storage device 120 can also be connected to the sewer pipe 700 via a floor drain 500. The waste storage device 120 can filter the solid-liquid mixture, storing the wet solid waste within it. Simultaneously, it can discharge the wastewater from the solid-liquid mixture into the sewer pipe 700 via the floor drain 500. This timely drainage of wastewater further saves space within the waste storage device 120, reduces the frequency of user cleaning, and prevents blockage of the sewer pipe 700. Of course, in some cases, the waste storage device 120 may not be installed in the cleaning base station 100, and the waste may be directly discharged into the sewer pipe 700 through the cleaning base station 100. This setting method has a certain risk of clogging the sewer pipe 700.

[0065] As can be seen from the above, the waste collected by the cleaning equipment 200 may include moisture. This waste, after being transferred to the cleaning base station 100, becomes wet waste (i.e., solid waste containing moisture or filtered, moistened solid waste) and is stored in the cleaning base station 100. Given the low frequency of cleaning by users, this means that wet waste needs to be stored in the waste storage device 120 for a relatively long time. However, the longer the storage time, the more easily bacteria grow in the wet waste, and even unpleasant odors may develop. To meet the requirement of longer storage time, the wet waste usually needs to be dried into dry waste before storage. During this process, sometimes an airflow generating device, such as a fan 131, is used to generate airflow to remove the moisture generated during drying or to accelerate the airflow to improve drying efficiency. However, since the airflow passing through the waste may have odors or bacteria, if this airflow enters the room, it will cause a poor user experience. Therefore, this portion of the airflow is drained through the floor drain 500 into the sewer pipe 700. Figure 1-4 As shown, this is to prevent odors or bacteria from entering the room. However, the air pressure generated during the discharge process may damage the liquid seal 800 in the drain pipe 700, causing the liquid seal to fail. Figure 5A and 5B The diagrams show the liquid seal in effect and in effect, respectively. Therefore, after the gaseous emissions are discharged, the odor in the drain pipe 700 can spread back into the indoor environment via the cleaning base station 100 or the connection between the cleaning base station 100 and the floor drain 500, causing an odor even if the cleaning base station 100 contains dry waste. For example, when using the fan 131 to dry the mop, the air outlet of the drying path can be connected to the drain pipe 700 to prevent bacteria from spreading into the indoor environment. In this case, gaseous emissions may also occur, causing the liquid seal 800 in the drain pipe 700 to be damaged. Of course, this application does not exclude the possibility that gaseous emissions may occur for other reasons and be discharged into the drain pipe 700 via the cleaning base station 100.

[0066] The principle of this invention will be explained below using the example of drying wet waste to generate gaseous emissions.

[0067] like Figure 1As shown, the cleaning base station 100 may have a sewage inlet 111 and a sewage outlet 112. A waste storage device 120 may be provided between the sewage inlet 111 and the sewage outlet 112. The waste storage device 120 may include a storage compartment 121 and a filter element 122, which may be disposed within the storage compartment 121. The filter element 122 may be any existing or future form of filter device. For example, in the illustrated embodiment, the filter element 122 may be a filter plate with multiple filter holes. In other embodiments not shown, the filter element 122 may also be a bag-shaped form with filtering function. In other embodiments, the filter element 122 is a box-shaped filter element 122 with multiple filter holes on each sidewall. Optionally, the filter element 122 divides the storage chamber 121 into a solid waste chamber and a water passage chamber, wherein the solid waste chamber is connected to the inlet 111 and the water passage chamber is connected to the outlet 112. Preferably, the solid waste chamber is above the water passage chamber, so that gravity can be used to separate the waste entering the solid waste chamber, allowing the solid waste to remain in the solid waste chamber and the wastewater to be discharged through the water passage chamber. The solid waste chamber may have a first connection port 1211, and the water passage chamber may have a second connection port 1212. The first connection port 1211 may be connected to the inlet 111, and the second connection port 1212 may be connected to the outlet 112. After the waste enters the cleaning base station 100 through the inlet 111, it will enter the storage chamber 121 through the first connection port 1211. Optionally, the filter element 122 may also be located at the second connection port 1212, so that the entire storage chamber 121 can be used to store solid waste, thereby increasing the storage space of the storage chamber 121. In this case, the size of the filter element 122 will be relatively small, resulting in a decrease in its filtration efficiency. Those skilled in the art can select the placement and size of the filter element 122 as needed. Due to the arrangement of the filter element 122, the waste entering the storage compartment 121 will be separated into two categories: one is sewage containing small, fine debris, which will be discharged from the second connection port 1212 to the drain port 112, and then discharged from the drain port 112 to the outside of the base station body 110; the other is larger solid waste that cannot be directly discharged to the outside of the base station body 110, which will be filtered by the filter element 122 and stored in the storage compartment 121 as wet waste.

[0068] Figure 6-10A cleaning base station 100 according to an exemplary embodiment of this application is shown from different angles. The cleaning base station 100 may include a base station body 110, on which the aforementioned inlet 111, outlet 112, and waste storage device 120 may all be disposed. The cleaning base station 100 may also include a drying device 130. The drying device 130 may include a fan 131. The fan 131 may be configured to blow air along an air supply path into the storage compartment 121 of the waste storage device 120. The air supply path refers to the path along which the airflow moves when the fan 131 blows air into the storage compartment 121. In the illustrated embodiment, the drying device 130 is connected to a first connection port 1211. In this case, the air supply path is the path along which the airflow generated by the fan 131 moves from the pipe to the first connection port 1211 and finally reaches the storage compartment 121. Optionally, the drying device 130 may also be connected to the storage compartment 121 through an inlet other than the first connection port 1211. In other embodiments not shown, the drying device 130 may also be located inside the storage chamber 121, in which case the air supply path is also located inside the storage chamber 121. Optionally, the drying device 130 may further include a heater 132, which may be located in the air supply path. The heater 132 may be located at any position on the air supply path. For example, in the illustrated embodiment, the drying device 130 is connected to the first connection port 1211 via a pipe, and the heater 132 may be located at any position on this pipe. When the heater 132 is turned on, it can heat the airflow generated by the fan 131, so that the airflow entering the storage chamber 121 is at a higher temperature, thereby using this higher temperature airflow to dry the wet waste retained in the storage chamber 121. In other embodiments not shown, the heater 132 may also be located around the storage chamber 121 to directly heat the storage chamber 121, thereby improving the drying efficiency within the storage chamber 121.

[0069] By installing a filter element 122 inside the waste storage device 120, waste entering the storage chamber 121 from the inlet 111 can be filtered. The filtered wastewater is discharged directly to the outside through the outlet 112, for example, directly into the sewer pipe 700. The wet waste remaining after filtration can be left in the storage chamber 121 and further dried using the drying device 130. The dried waste will not produce odor even after being left for several days, thus reducing the frequency of cleaning the storage chamber 121 and greatly improving the user experience. Moreover, the filter element 122 may become clogged by wet waste during the sewage discharge process. Therefore, during sewage discharge, the fan 131 can be turned on while the heater 132 is turned off, which can accelerate the sewage discharge and shorten the overall sewage discharge time. The installation of the drying device 130 allows users to avoid frequent cleaning of the storage chamber 121 when using the cleaning base station 100.

[0070] like Figure 9-10 As shown, the cleaning base station 100 may further include a first pipe 140 and a second pipe 150. The first pipe 140 can be connected between the first connection port 1211 and the fan 131 to define the air supply path. The airflow generated by the fan 131 will move through the first pipe 140 to the first connection port 1211, and then the airflow can enter the storage chamber 121. In one embodiment, as shown, the first pipe 140 may be provided with a branch interface 142, and the second pipe 150 can be connected between the branch interface 142 and the sewage inlet 111. In the illustrated embodiment, the first pipe 140 and the second pipe 150 are generally formed in a "Y" shape. In other embodiments not shown, the first pipe 140 and the second pipe 150 can be of any structure. The second pipe 150 may be connected at one end to the sewage inlet 111 and at the other end to the branch interface 142. It is understood that the connection mentioned here can be of any form. For example, one end of the second pipe 150 can be connected to the inlet 111 by welding, screw connection, or snap-fit, and the other end of the second pipe 150 can be connected to the branch interface 142 by welding, screw connection, or integral molding, etc. Optionally, a branch interface 142 can also be provided on the second pipe 150, and the first pipe 140 is connected to the branch interface 142.

[0071] In some embodiments, in order to allow the waste to enter the storage chamber 121 smoothly, the pipe from the inlet 111 to the storage chamber 121 usually needs to be a straight pipe. However, if it is a straight pipe, the size of the cleaning base station 100 may increase, and the space of the cleaning base station 100 cannot be effectively utilized. The large size of the cleaning base station 100 also places higher demands on the user's installation space. Therefore, due to the limited size of the cleaning base station 100, in reality, the pipe from the inlet 111 to the storage chamber 121 may have bends. The bends are prone to the accumulation of solid waste in the waste, causing pipe blockage. Therefore, in some embodiments, the branch interface 142 can be located upstream of the pipe bend. In this way, the wind power of the fan 131 can be used to push the waste accumulated at the bend toward the storage chamber 121, preventing blockage at the bend.

[0072] In some embodiments not shown, the branch interface 142 may not be used; instead, the solid waste bin and the inlet 111 are directly connected via the second pipe 150. Specifically, one end of the second pipe 150 can form the inlet 111, and the second end of the second pipe 150 can be directly connected to the first connection port 1211. The first pipe 140 can also be directly connected to the first connection port 1211. Alternatively, a third connection port may be formed on the solid waste bin, and the second end of the second pipe 150 is connected to the third connection port. The first pipe 140 can then be connected to the first connection port 1211.

[0073] When the cleaning base station 100 with fan 131 is in use, waste enters the second pipe 150 through the inlet 111 and then enters the storage chamber 121. Inside the storage chamber 121, the waste is separated into sewage and wet waste by the filter element 122. The sewage is discharged to the outside of the cleaning base station 100 through the second connection port 1212 and the drain port 112, while the wet waste remains in the solid waste compartment within the storage chamber 121. During the process of waste entering the storage chamber 121, the fan 131 can be turned on. The airflow generated by the fan 131 enters the storage chamber 121 through the first pipe 140. The airflow continues to flow towards the second connection port 1212 within the storage chamber 121. During this process, the flowing airflow can carry the sewage towards the second connection port 1212, thus accelerating the discharge of sewage to the drain port 112. Therefore, the airflow generated by the fan 131 allows the dirt reaching the branch interface 142 to slide faster into the storage chamber 121. The airflow also creates positive pressure inside the storage chamber 121, causing the wastewater formed from the filtered waste to be discharged to the drain outlet 112 more quickly. After the cleaning equipment 200 completes one discharge of dirt to the cleaning base station 100, and after the dirt in the storage chamber 121 has been completely separated (i.e., after the separation of wet waste and wastewater), the fan 131 can be turned on. The airflow generated by the fan 131 flows into the storage chamber 121 and carries away the moisture from the storage chamber through the drain outlet 112, thus drying the wet waste in the solid waste chamber to prevent bacterial growth and even foul odors.

[0074] Furthermore, with the blower 131 running and the heater 132 activated, the airflow generated by the blower 131 is heated by the heater 132, making the airflow entering the storage chamber 121 a flowing hot airflow. This raises the temperature inside the storage chamber 121, thereby drying the wet waste retained inside. The dried waste, after drying, will no longer emit odors and can be stored for a long time, reducing the frequency of cleaning the storage chamber 121 and improving the user experience. Connecting the inlet 111 and the storage chamber 121 via a pipe enhances the guidance of waste movement and improves the overall sealing of the equipment, preventing waste leakage during movement. Similarly, the blower 131 is connected to the storage chamber 121 via a pipe, with the airflow path formed within the pipe. When the drying device 130 is operating, odors emitted by the waste are less likely to leak out, further improving the user experience.

[0075] like Figure 9As shown, a first check valve 141 can be installed on the first pipe 140. The first check valve 141 can be configured to be closed under normal conditions and open when the blower 131 blows air towards the waste storage device 120. The first check valve 141 can be any existing or future check valve, such as a gravity check valve, torsion spring check valve, spring check valve, magnetic check valve, or duckbill check valve. The first check valve 141 can be configured to be closed under normal conditions, that is, the first pipe 140 is in an open circuit state under normal conditions, and the two sides of the first check valve 141 on the first pipe 140 are not connected to each other. In some embodiments, when the blower 131 blows air towards the waste storage device 120, the airflow generated by the blower 131 causes the first one-way valve 141 to open. For example, when the first one-way valve 141 is a magnetic one-way valve, it is normally kept closed due to magnetic attraction. When the blower 131 is turned on, the airflow generated by the blower 131 creates positive pressure in the portion of the first pipe 140 near the blower 131. This positive pressure can overcome the magnetic attraction of the magnetic one-way valve 141, causing it to open. In other embodiments, the first one-way valve 141 can be opened when the blower 131 is turned on and closed when drying is complete. In this case, the first one-way valve 141 can be a regular switch, and its one-way conduction function can be achieved simply by controlling the opening and closing of the switch. The first one-way valve 141 ensures that the first pipe 140 is in a closed state only when the fan 131 is turned on, and is normally in a closed state. This ensures that bacteria and odors generated by garbage will not flow back into the indoor environment through the first pipe 140, resulting in a better user experience.

[0076] Combination Figure 9-10As shown, a second check valve 151 may also be provided on the second pipe 150. The second check valve 151 can be configured to be closed under normal conditions and open when waste enters the waste storage device 120 along the inlet 111. The second check valve 151 can be any existing or future check valve, such as a gravity check valve, torsion spring check valve, spring check valve, magnetic check valve, or duckbill check valve. The second check valve 151 can be configured to be closed under normal conditions, that is, the second pipe 150 is in an open circuit state under normal conditions, and the two sides of the second pipe 150 are not connected to each other. In some embodiments, when waste enters the waste storage device 120 along the inlet 111, the weight of the waste will cause the second check valve 151 to open. The weight of the waste mentioned here includes the weight of the wet waste itself and the weight of the wastewater. For example, when the second one-way valve 151 is a magnetic one-way valve, it remains closed under normal conditions due to magnetic attraction. When waste enters the second pipe 150 through the inlet 111, the weight of the waste overcomes the magnetic attraction of the second one-way valve 151, causing it to open. In other embodiments, when the cleaning equipment is detected discharging waste into the cleaning base station, the second one-way valve 151 can be opened, and closed when the discharge is complete. In this case, the second one-way valve 151 can be a regular switch; its one-way conduction function is achieved simply by controlling the opening and closing of the switch. The design of the second one-way valve 151 ensures that the second pipe 150 is only in a closed state when waste enters it, and is normally in a closed state. This ensures that odors and bacteria generated by waste will not flow back into the indoor environment through the second pipe 150, resulting in a better user experience.

[0077] Furthermore, in some embodiments, see [reference] Figure 1 The floor drain 500 is connected to the sewer pipe 700. The drain outlet 112 of the cleaning base station 100 is sealed to the floor drain 500, and the floor drain 500 can isolate the sewer pipe 700 from the outside world to prevent odors and bacteria in the sewer pipe 700 from leaking to the outside through the floor drain 500. Thus, a complete seal is achieved from the sewage inlet 111 of the cleaning base station 100 to the floor drain 500 to ensure that odors and bacteria do not leak out.

[0078] The aforementioned gaseous emissions may be generated during the drying process of wet waste. Specifically, when wet waste is dried using an airflow generating device such as a blower, the airflow passing through the wet waste becomes gaseous emissions. Exemplarily, gaseous emissions may also be generated under one or more of the following conditions:

[0079] 1) The mop or roller of the drying and cleaning equipment 200 (if any): The mop or roller is dried by an airflow generating device such as a fan, and the airflow is discharged as gas after passing through the mop or roller.

[0080] 2) Transferring waste from cleaning equipment 200 to cleaning base station 100: To smoothly transfer waste from cleaning equipment 200 to cleaning base station 100, an airflow generating device such as a fan is used to generate airflow along the transfer path. The generated airflow, after completing its assist, is discharged as gas. Waste in the dust collection container 210 of cleaning equipment 200 can be transferred to waste storage device 120 under gravity. In other embodiments not shown, waste in the dust collection container 210 of cleaning equipment 200 can be transferred to waste storage device 120 under the positive pressure generated by fan 131. Since waste storage device 120 is connected to floor drain 500, the positive pressure during waste transfer may also cause damage to the liquid seal 800 in the drain pipe 700 connected to floor drain 500.

[0081] Optionally, the disrupted liquid seal 800 in the drain pipe 700 may be established when the cleaning base station 100 discharges liquid waste. Optionally, the disrupted liquid seal 800 in the drain pipe 700 may also be established by liquid waste discharged from other drainage devices (not shown). Typically, the cleaning base station 100 may share the same floor drain with other drainage devices such as washing machines, and the liquid seal 800 established by other drainage devices in the drain pipe 700 may also be disrupted by gaseous emissions from the cleaning base station 100.

[0082] To remedy the failure of the liquid seal 800 in the drain pipe 700 connected to the drain 500 caused by the discharge of gaseous substances from the cleaning base station 100 into the drain 500, please refer to [link to relevant documentation]. Figure 1-4 The cleaning station 100 may include a discharge channel 300, an execution component (not shown), and a control component (not shown). The discharge channel 300 is used to discharge gaseous emissions and supply liquids to the drain 500. Figure 1-4 In the illustrated embodiment, one end of the discharge channel 300 can be connected to the outlet of the waste storage device 120, and the other end of the discharge channel 300 can be connected to the floor drain 500. Gas emissions from the waste storage device 120 can be discharged to the floor drain 500 via the discharge channel 300. Furthermore, the discharge channel 300 can also be used to supply liquids.

[0083] exist Figure 1In the illustrated embodiment, gaseous emissions and supplied liquid can be delivered to drain 500 via the same discharge channel 300. Regardless of whether the gaseous emissions are generated in the cleaning base station 100 or in the cleaning device 200 connected to the cleaning base station 100, the emissions can be discharged into drain 500 via discharge channel 300. These gaseous emissions may cause the liquid seal 800 in the drain pipe 700 connected to drain 500 to fail. After the gaseous emissions have been discharged, liquid for re-establishing the liquid seal can be supplied via discharge channel 300. The liquid used to re-establish the liquid seal can originate from the cleaning base station 100, the cleaning device 200, or an external water source. The drain outlet 112 of the cleaning base station 100 can be located on the discharge channel 300 (i.e., the drain outlet 112 forms part of the discharge channel 300). For existing cleaning base stations (i.e., existing base stations), the discharge channel 300 can be connected to their existing drain outlet 112 to avoid excessive modifications to the structure of the existing cleaning base station. Since the drain outlet 112 is connected to the waste storage device 120, the discharge channel 300 can be indirectly connected to the waste storage device 120. This configuration is more flexible, and the discharge channel 300 can be selected as an option. Of course, for existing cleaning base stations, the discharge channel 300 can also be directly connected to the waste storage device 120. In this case, any point on the discharge channel 300 can be considered as the drain outlet 112. The advantage of directly connecting the discharge channel 300 to the waste storage device 120 is that it reduces the number of connection points, thereby reducing the risk of water and / or air leakage, and it also makes the structure of the cleaning base station 100 simpler. Of course, for newly developed cleaning base stations, the discharge channel 300 can be connected to its drain outlet or directly to the waste storage device 120. In this embodiment, since the gaseous emissions and the supplied liquid can be transported to the floor drain 500 through the same discharge channel 300, and in order to prevent the dried garbage in the garbage storage device 120 from being repeatedly wetted, the dried garbage can be moved to another enclosed space in the garbage storage device 120 after each drying process, so as to prevent the liquid from repeatedly wetting and drying the dried garbage during each sewage discharge or liquid replenishment process.

[0084] In another embodiment, the gaseous emissions and the supplied liquid can be delivered to the floor drain via different discharge channels. For example... Figure 2 As shown, the discharge channel 300 may include a sewage discharge channel 310 and a liquid replenishment channel 320. The sewage discharge channel 310 is used to discharge gaseous emissions. The liquid replenishment channel 320 is used to supply liquid for liquid replenishment. The liquid replenishment channel 320 may be located inside the base station body 110. Optionally, as... Figure 3-4As shown, the liquid sealing channel 320 can be located outside the base station body 110. Optionally, the liquid sealing channel 320 can also be partially located inside the base station body 110 and partially located outside the base station body 110. The location of the liquid sealing channel 320 can be related to the location of the water source it is connected to. Figure 2 As shown, the water source 900 is located inside the base station body 110. In this case, it is preferable that the liquid replenishment sealing channel 320 is also located inside the base station body 110. Alternatively, the water source can be located within the cleaning equipment 200. In this case, the liquid replenishment sealing channel 320 can be located either inside or outside the base station body 110. Figure 3 As shown, the water source 900 is located outside the base station body 110. The liquid replenishment sealing channel 320 can be located outside the base station body 110. The liquid replenishment sealing channel 320 can be connected to the sewage discharge channel 310. After the sewage discharge channel 310 and the liquid replenishment sealing channel 320 are connected, they are both connected to the floor drain 500. Optionally, as shown... Figure 4 As shown, the liquid seal channel 320 located outside the base station body 110 can be independent of the sewage discharge channel 310. The sewage discharge channel 310 and the liquid seal channel 320 can be connected to the floor drain 500 respectively. Of course, if the water source is located outside the base station body 110, the liquid seal channel 320 can also be located inside the base station body 110. This allows for a simpler appearance for the cleaning base station 100.

[0085] It should be noted that, in Figure 1-4 In the embodiments shown, the discharge channels 300 are directly connected to the floor drain. In other embodiments not shown, for ease of installation or transportation, the discharge channels 300 may also be indirectly connected to the floor drain via pipes.

[0086] For example, the supplied liquid water source may be municipal tap water. For example, the supplied liquid water source may be the water storage container of the cleaning base station 100 and / or the cleaning equipment 200, such as the clean water tank of the cleaning equipment 200 and / or the wastewater tank of the cleaning base station 100, etc.

[0087] The actuator can be connected to the discharge channel 300 to control the supply of liquid.

[0088] For example, the execution component may be connected between the water source 900 and the discharge channel 300, including the case where the execution component is located on the discharge channel 300.

[0089] When the discharge channel 300 includes a sewage discharge channel 310 and a liquid replenishment channel 320, the actuator can be connected between the water source 900 and the liquid replenishment channel 320, including the case where the actuator is installed on the liquid replenishment channel 320. A suitable actuator can be selected depending on the water source supplying the liquid.

[0090] For example, the execution component may include a pumping device disposed within the cleaning base station 100, and the inlet of the discharge channel 300 may be connected to the pumping device. By controlling the pumping device, liquid can be supplied into the discharge channel to achieve a liquid replenishment and sealing operation. The pumping device is more suitable for water sources with low water pressure, such as the water source within the cleaning base station 100.

[0091] Exemplarily, the actuating component may include a control valve. The inlet of the control valve is for connection to a municipal water source or a water source within the cleaning station 100 (e.g., a water source located at a higher elevation that can be supplied to a floor drain by gravity). The outlet of the control valve may be connected to the inlet of the replenishment seal channel 320. Exemplarily, the control valve may include a solenoid valve.

[0092] The control component, after the gaseous emissions have been discharged, drives the actuator to supply liquid to the drain 500, thereby establishing a liquid seal in the sewer pipe 700 connected to the drain 500. The control component can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips and their peripheral circuits, such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs). Optionally, the control component can also be electrically connected to the aforementioned drying device 130. The control component can control the drying device 130 to dry the waste in the waste storage device 120, and after drying, drive the actuator to supply liquid to the drain 500.

[0093] The cleaning base station 100 provided in this application needs to discharge gaseous emissions into a floor drain 500. These emissions may disrupt the liquid seal in the drain pipe 700 connected to the floor drain 500. After the gaseous emissions are discharged, the control component of the cleaning base station 100 can drive the execution component to supply liquid from the discharge channel 300 to the floor drain, thereby re-establishing the liquid seal in the drain pipe 700 connected to the floor drain 500 to compensate for the liquid that was squeezed out by the positive pressure of the gas during the emission process. In this way, without affecting the gaseous emissions from the cleaning base station 100, by re-establishing the liquid seal in the drain pipe 700, it is ensured that even if the discharge channel 300 is not completely sealed or the floor drain 500 does not isolate the drain pipe 700 from the outside environment, odors from the drain pipe 700 will not enter the room, thus improving the user experience.

[0094] In some embodiments, regardless of the device used (e.g., a timing device, a flow metering function built into the water pump, or an additional flow metering device), the control component must ensure that after the gas emissions are discharged, the liquid supply to the drain 500 by the drive actuator reaches a preset amount. The preset amount can be determined based on the maximum amount of liquid required to establish a liquid seal in a commercially available drain pipe 700. For drain pipes 700 where a liquid seal can be established with only a small amount of liquid, or in cases where the liquid seal is not completely destroyed, excess liquid can be directly drained from the drain pipe 700 without affecting the normal use of the drain 500 and the drain pipe 700.

[0095] In one embodiment, the control component drives the execution component to supply liquid to the drain, including performing the following operations: controlling the execution component to turn on and starting a timer from the moment the execution component turns on; when the timed reaches a preset time, controlling the execution component to turn off, so that a preset amount of liquid is supplied to the drain. Controlling the amount of liquid supplied to the drain by controlling the duration of liquid supply simplifies the control logic and eliminates the need for additional detection components, thus reducing costs. Furthermore, the entire liquid seal establishment process can be completed automatically without user intervention, making the cleaning base station 100 more intelligent and improving the user experience. When the liquid seal channel 320 used for replenishing the liquid seal is relatively narrow, the liquid seal channel 320 has a certain flow-limiting effect. Therefore, the flow rate of liquid supplied through the liquid seal channel 320 can be roughly determined, and the amount of liquid supplied to the drain can be controlled by controlling the preset time the execution component turns on. For example, when the execution component includes a water pump, the water pump typically has a flow-controlling function, so the amount of liquid supplied to the drain can also be controlled by controlling the preset time the execution component turns on. For example, the water source can also be configured to hold a quantity of liquid greater than a preset amount. In this case, the preset time for the execution component to start only needs to be greater than or equal to the time required to drain the predetermined amount of water.

[0096] In another embodiment, the cleaning base station 100 also includes a flow detector for detecting the supply flow rate of liquid. Exemplarily, the flow detector can be installed on the discharge channel; or on the pipeline between the discharge channel and the execution component; or on the pipeline between the execution component and the water source. The aforementioned control component drives the execution component to supply liquid to the drain, including performing the following operations: controlling the execution component to turn on and determining the total supply of liquid based on the supply flow rate; when the calculated total supply reaches a preset amount, controlling the execution component to turn off. Water pressure in municipal water sources may vary in different areas, or the flow rate of liquid drawn from the source using different pumping devices may vary. By detecting the actual supply flow rate using a flow detector, the total supply of liquid to the drain can be accurately controlled, thereby preventing incomplete liquid seal establishment or waste due to excess liquid being lost through the drain. Furthermore, the entire liquid seal establishment process can be completed automatically without user intervention, making the cleaning base station 100 more intelligent and improving the user experience.

[0097] In some embodiments where the emission channel 300 may include a sludge discharge channel 310 for discharging gaseous emissions and a liquid replenishment channel 320 for supplying liquids, a dedicated connector assembly may be provided to facilitate the installation of the emission channel 300 on the base station body of various types of clean base stations (especially existing clean base stations). Figure 11-15 A connector assembly 600 according to an exemplary embodiment of the present invention is shown from various angles. This connector assembly 600 will now be described in detail with reference to the accompanying drawings.

[0098] like Figure 11-15 As shown, the connector assembly 600 may include a connector drain channel and a first connector 611. The connector drain channel is connected to the drain port 112 of the base station body 110 (see...). Figure 9-10 Between the first connector 611 and the first joint 611. The structure of the drain channel of the connector will be described in detail later. The first connector 611 is connected to a drain pipe 620 for connecting to the floor drain 500. Refer to the previous section. Figure 2 and 4 The described sewage discharge channel 310 may include a connector sewage discharge channel, a first connector 611, and a sewage discharge pipe 620. The first connector 611 and the sewage discharge pipe 620 may be located outside the base station body and can be easily connected to the base station body 110 of various cleaning base stations. Figure 2 In the illustrated embodiment, the sewage discharge channel 310 may further include an internal sewage discharge pipe connected between the waste storage device 120 and the sewage outlet 112. Wastewater filtered from the waste storage device 120 may be discharged sequentially through the internal sewage discharge pipe, the sewage outlet 112, the connector sewage discharge channel and the first connector 611 of the connector assembly 600, and the sewage discharge pipe 620 into the sewer pipe 700 connected to the floor drain 500.

[0099] like Figure 11-15 As shown, the connector assembly 600 may further include a connector liquid seal channel and a second connector 612. The inlet of the connector liquid seal channel is connected to a water source 900 supplying liquid for liquid seal, and the second connector 612 is located at the outlet of the connector liquid seal channel. The structure of the connector liquid seal channel will be described in detail later. The second connector 612 is connected to a sealant pipe 630 for connecting to a floor drain 500. The liquid seal channel 320 may include the connector liquid seal channel, the second connector 612, and the sealant pipe 630. The second connector 612 and the sealant pipe 630 may be located outside the base station body, allowing for easy connection to the base station body of various clean base stations. (Refer to previous text) Figure 2 The described liquid seal channel 320 may also include an internal liquid seal conduit connected within the cleaning base station between the water source 900 and the drain outlet 112. Water supplied by the water source 900 can be discharged sequentially through this internal liquid seal conduit, the drain outlet 112, the connector assembly 600, and the liquid seal pipe 630 to the floor drain 500, thereby establishing a liquid seal 800 in the sewer pipe 700 connected to the floor drain 500. Optionally, the water source 900 (including municipal water) for liquid seal can also be located outside the cleaning base station. A portion of the liquid seal conduit connecting the external water source 900 and the drain outlet 112 can be entirely or partially located within the base station body.

[0100] The outlet of the drain pipe 620 can be connected to the floor drain 500 in the user's home. Because the external piping connecting the cleaning base station 100 to the floor drain 500 operates in complex ways at the user's end, it is necessary to consider the possibility of pipe bends, especially in some homes where, to prevent backflow, the top of the floor drain 500 may extend upwards into a connecting pipe 580 nearly 0.5m above the ground. Figure 17-18As shown. Even if the drain 500 is not higher than the ground, when the drain pipe 620 is vertically inserted into the drain 500, the section of the drain pipe 620 near the vertical section may drag on the ground due to its own weight and / or the length of the drain pipe itself, resulting in a large bend between this section and the vertical section. This can easily cause dirt to accumulate in the drain pipe 620. To prevent large debris from getting stuck in the drain pipe 620, the drain pipe 620 of the cleaning base station 100 is usually a pipe with a large diameter. If the drain pipe 620 with a large diameter is used to replenish the drain pipe, the drain pipe 620 will need to be filled completely before the excess liquid can enter the drain pipe 700. This results in water waste and may easily cause backflow, leading to a poor user experience. Therefore, in some embodiments, the replenishment seal channel 320 is set independently of the drain channel 310, and the replenishment seal channel 320 has greater design flexibility. For example, the replenishment seal channel 320 can be made narrower, thereby limiting the maximum supply flow of liquid.

[0101] In cases where the liquid seal is disrupted due to gas emissions from dried waste, a new liquid seal needs to be established in the drain after drying. The fact that the replenishment liquid seal channel 320 is independent of the discharge channel 310 also provides the benefit that the liquid used for replenishment will not affect the already dried waste. In other embodiments, if the outlets of the replenishment liquid seal channel 320 and the discharge channel 310 converge at a point downstream of the waste storage device 120, the liquid supplied by the replenishment liquid seal channel 320 will not affect the dried waste within the waste storage device 120.

[0102] For example, the inner diameter of the seal-up pipe 630 can be smaller than the inner diameter of the drain pipe 620. This limits the flow rate of liquid flowing out through the seal-up pipe 630, allowing for precise control of the total liquid supply when re-establishing the liquid seal with a small flow rate, thus preventing waste. Furthermore, the seal-up pipe 630 may be bent when connected to the drain 500. Using a thinner seal-up pipe 630 avoids excessive water accumulation or backflow at the bend in the seal-up pipe 630 when the liquid seal is established.

[0103] For example, such as Figure 11-12 As shown, the first connector 611 and the second connector 612 can face the same side. The drain pipe 620 and the sealing pipe 630, which are respectively connected to the first connector 611 and the second connector 612, can also be set to face the same side, so that they can be connected to the same floor drain. When installing the cleaning base station 100, it is convenient to plan the placement of the pipeline, avoids the inconvenience to users caused by messy pipeline layout, and saves space.

[0104] Figure 16A floor drain 500 according to an exemplary embodiment of the present invention is shown. As shown, the floor drain 500 has a first floor drain channel 510, a second floor drain channel 520, and a discharge channel 570. The inlet of the first floor drain channel 510 and the inlet of the second floor drain channel 520 are respectively connected to the outlet of the sewage discharge channel 310 and the outlet of the liquid seal channel 320, for example, to the sewage pipe 620 and the liquid seal pipe 630, respectively. The outlet of the first floor drain channel 510 and the outlet of the second floor drain channel 520 can be connected to the discharge channel 570. The first floor drain channel 510 and the second floor drain channel 520 can converge into a single pipeline within the floor drain 500. When waste enters the floor drain 500, it can be smoothly discharged into the sewer pipe 700 without needing to distinguish different paths for waste in different states (including gaseous, liquid, and solid).

[0105] To facilitate the connection and installation of the first drain channel 510 with the sewage pipe 620, and to facilitate the connection and installation of the second drain channel 520 with the sealing pipe 630, the first drain channel 510 and the second drain channel 520 typically protrude beyond other parts of the drain 500. This may result in bends in the outlet sections of the sewage pipe 620 and the sealing pipe 630, such as... Figure 16 As shown, fluid accumulation occurs at the bend. Choosing a thinner 630 sealant can reduce the amount of fluid accumulation at this point.

[0106] Figure 17-18 A floor drain 500 according to another exemplary embodiment of the present invention is shown. As shown, the floor drain 500 may have a fourth floor drain channel 560 and a discharge channel 570. The inlet of the fourth floor drain channel 560 may communicate with the discharge channel. When the discharge channel includes a sewage channel 310 for discharging gaseous emissions and a liquid seal channel 320 for supplying liquid, the floor drain 500 may be connected with a tee connector 400. The tee connector 400 may have a first inlet 410, a second inlet 420, and an outlet 430. A sewage pipe 620 forming part of the sewage channel 310 and a liquid seal pipe 630 forming part of the liquid seal channel 320 may be connected to the first inlet 410 and the second inlet 420, respectively. The outlet 430 of the tee connector 400 may be connected to the floor drain 500, for example, via a connecting pipe 580 of the floor drain 500 to the fourth floor drain channel 560. The outlet of the fourth floor drain channel 560 may communicate with the discharge channel 570.

[0107] exist Figure 17-18In the illustrated embodiment, the tee connector 400 is located at the floor drain 500. In other embodiments not shown, the tee connector 400 may also be located at any suitable position on the discharge channel 300, as long as it allows the replenishment seal channel 320 and the sewage discharge channel 310 to merge into one channel downstream of the waste storage device 120, thereby enabling sewage discharge and liquid replenishment through the fourth floor drain channel 560.

[0108] For example, such as Figure 17-18 As shown, the drain 500 may also include a third drain channel 530. One end of the third drain channel 530 is connected to the external environment (e.g., indoors).

[0109] In some embodiments, a drain hole 531 may be provided on the upper surface of the drain 500. The other end of the third drain channel 530 may be connected to the discharge channel 570, and the other end may be connected to the drain hole 531. When the drain 500 is embedded in the ground, the upper surface of the drain hole 531 is not higher than the ground, so that water on the ground can enter the drain 500 through the drain hole 531 and drain into the sewer pipe, such as in a bathroom or balcony drain, where water in the bathroom or balcony gathers in the drain hole 531.

[0110] In other embodiments, one end of the third floor drain channel can be connected to a drain appliance or drainage device such as a washing machine, and the other end of the third floor drain channel can be connected to a discharge channel 570 for the drain appliance or drainage device to discharge sewage.

[0111] In some embodiments, for the practicality of the floor drain, the third floor drain channel may simultaneously include a drain hole 531 for collecting water on the floor and a passage connecting to a drainage appliance or drainage device to help the drainage appliance or drainage device drain water through the floor drain to the sewer pipe 700. Therefore, the third floor drain channel has any structure that can be connected to the external environment.

[0112] In some embodiments, the third drain channel 530 is connected to the external environment (e.g., indoors). A check element 540 may be provided within the third drain channel 530 to prevent gas and / or liquid in the drain pipe 50 from leaking into the external environment and affecting user experience. Specifically, for example, leakage may occur through a drain hole 531. The check element 540 is configured to allow contaminants from the external environment to enter the drain channel 570 via the third drain channel 530 and then be discharged into the sewer pipe; however, contaminants cannot enter the external environment through the third drain channel 530 against the aforementioned fluid flow direction. Exemplarily, the check element 540 may be made of an elastic material, such as an elastic diaphragm, a duckbill valve, etc. The check element 540 is capable of blocking the third drain channel 530 in its natural state. When waste enters the third drain channel 530, the check element 540 deforms under pressure, allowing the waste to be discharged through the third drain channel 530 into the drain 500 and then into the sewer pipe. When the pressure disappears, the check element 540 returns to its original shape, closing the third drain channel 530 and preventing waste or odors, especially gaseous emissions, from leaking from the drain 500 into the user's home. As mentioned earlier, the sewage channel 310 connected to the first drain channel 510 discharges gaseous emissions into the drain 500; in this case, the check element 540 effectively prevents the gaseous emissions from entering the external environment through the third drain channel 530.

[0113] It should be noted that the aforementioned third drain channel 530 and check valve element 540 can also be increased to... Figure 16 In the drain shown.

[0114] Alternatively, for some clean base stations (especially existing clean base stations), the sewage discharge channel 310 can also be an existing structure of these clean base stations, simply by adding a liquid seal channel 320 to these clean base stations. In this case, the sewage discharge channel 310 and the liquid seal channel 320 can utilize... Figure 17-18 The 400-type tee connector and the 500-type drain shown connect to the sewer pipe, such as... Figure 3 As shown; or the drain channel 310 and the liquid seal channel 320 can be used without any adapters. Figure 16 The type of floor drain 500 shown is connected to the drain pipe 700, such as... Figure 4 As shown. The choice of method may be related to the structure of the drain 500.

[0115] For example, return to the reference Figure 11-12As shown, the connector assembly 600 may include an adapter 610. A first connector 611 and a second connector 612 may be disposed on the adapter 610. The adapter 610 is configured to be rotatably and / or detachably mounted to the base station body 110 to change the orientation of the first connector 611 and the second connector 612. Therefore, the orientation of the first connector 611 and the second connector 612 can be adjusted after the adapter 610 is rotated relative to the base station body 110 and / or after being reinstalled on the base station body 110. In practical applications, the cleaning base station 100 is usually not moved after being installed in a user's home because it is positioned close to and connected to the floor drain. However, the position of the floor drain relative to the cleaning base station 100 may be different in different users' homes, so it is desirable to be able to adjust the orientation of the drain pipe 620 and the sealing pipe 630 to adapt to the floor drain position in different users' homes.

[0116] For example, the adapter 610 may have a first position and a second position relative to the base station body 110. When the adapter 610 is in the first position, the first connector 611 and the second connector 612 face a first direction. When the adapter 610 is in the second position, the first connector 611 and the second connector 612 face a second direction different from the first direction. Therefore, by adjusting the position of the adapter 610, the orientation of the first connector 611 and the second connector 612 can be adjusted, thereby adjusting the orientation of the drain pipe 620 and the sealing pipe 630 connected to the adapter 610, so as to facilitate the connection of the drain pipe 620 and the sealing pipe 630 to the floor drain. Figure 7-8 In the illustrated embodiment, the drain pipe 620 and the sealing pipe 630 are positioned facing left. In the illustrated embodiment, the first connector 611 and the second connector 612 can face left in the first station and right in the second station. Optionally, the first connector 611 and the second connector 612 can also be configured to face upward, downward, or any other desired direction in the second station. Of course, the first connector 611 and the second connector 612 can also face any direction other than left in the first station.

[0117] For example, such as Figure 11As shown, a first central channel 613 and a first peripheral channel 614 disposed around the first central channel 613 can be provided on the adapter 610. Exemplarily, the first peripheral channel 614 can surround the first central channel 613, for example, it can be concentrically disposed with the first central channel 613. Exemplarily, the first peripheral channel 614 can also be distributed dispersedly around the first central channel 613. The first central channel 613 can form part of one of the aforementioned connector drain channel and connector liquid seal channel, while the first peripheral channel 614 can form part of the other of the aforementioned connector drain channel and connector liquid seal channel. In the illustrated embodiment, the first central channel 613 communicates with the first connector 611, and the first peripheral channel 614 communicates with the second connector 612; therefore, the first central channel 613 forms part of the aforementioned connector drain channel, and the first peripheral channel 614 forms part of the aforementioned connector liquid seal channel. Alternatively, in other embodiments not shown, the first central channel 613 may be connected to the second connector 612, and the first peripheral channel 614 may be connected to the first connector 611. Thus, the first central channel 613 forms part of the aforementioned connector liquid seal channel, while the first peripheral channel 614 forms part of the aforementioned connector drain channel.

[0118] The advantage of setting the first peripheral channel 614 around the first central channel 613 is that, regardless of the angle of the adapter 610 relative to the base station body 110, it can ensure communication with both the drain outlet 112 of the base station body 110 and the water source for supplying the sealing liquid. This arrangement enhances the applicability of the adapter 610 and makes on-site installation of the cleaning base station 100 more convenient. Of course, to ensure that the adapter 610 can communicate with both the drain outlet 112 and the water source for supplying the sealing liquid in both the first and second work positions, the first peripheral channel 614 can include a first liquid sealing channel and a second liquid sealing channel. Regardless of the work position of the adapter 610, the first central channel 613 is always connected to the drain outlet 112. The first and second liquid sealing channels can be located around the first central channel 613. When the adapter 610 is in the first work position, the water source for supplying the sealing liquid can communicate with the first liquid sealing channel, while the second liquid sealing channel, being not connected to a water source, will not experience leakage problems. Similarly, when the adapter 610 is in the second position, the water source for supplying the replenishing seal liquid can be connected to the second replenishing seal channel, while the first replenishing seal channel will not have a leakage problem because it is not connected to the water source.

[0119] For example, such as Figure 11-12 As shown in Figures 14-15, the connector assembly 600 may also include components disposed on the base station body (see Figure 14-15). Figure 6-10 The waste drain rack 640 is mounted on the base station body 110. Exemplarily, the waste drain rack 640 can be fixedly installed on the waste drain port 112 of the base station body 110 (see...). Figure 9-10 ( ) place. For example Figure 14 As shown, the drain rack 640 can be fixed to the base station body by fasteners 646. The drain rack 640 can be provided with a second central channel 641 and a second peripheral channel 642 located around the second central channel 641. The first central channel 613 and the second central channel 641 are connected. The first peripheral channel 614 and the second peripheral channel 642 are connected. Thus, the first central channel 613 and the second central channel 641 together form one of the aforementioned connector drain channel and connector liquid seal channel; while the first peripheral channel 614 and the second peripheral channel 642 together form the other of the aforementioned connector drain channel and connector liquid seal channel. By setting the drain rack 640, excessive modifications to the existing clean base station design can be avoided. By installing the drain rack 640 at the drain outlet 112 of the existing clean base station design, the reversal function of the first connector 611 and the second connector 612 can be realized, thus reducing the cost of product upgrades.

[0120] The following will be combined with the appendix Figure 11-15 An embodiment of the connector drain channel and connector liquid seal channel is described. As shown in the figure, the adapter 610 may include a bend 615 forming a first central channel 613 and a first outer tube 616 surrounding the bend 615. A first peripheral channel 614 is formed between the bend 615 and the first outer tube 616. The drain bracket 640 may include a straight tube 643 forming a second central channel 641 and a second outer tube 644 surrounding the straight tube 643. A second peripheral channel 642 is formed between the straight tube 643 and the second outer tube 644. When the adapter 610 is connected to the base station body 110, the straight tube 643 and the bend 615 are sealed together, forming an inner channel. This inner channel may form one of the aforementioned connector drain channel and connector liquid seal channel. The second outer tube 644 and the first outer tube 616 are sealed together. The annular space between the second outer tube 644 and the first outer tube 616, and between the straight tube 643 and the bend 615. This annular space can form one of the aforementioned joint drain channel and joint liquid seal channel. Figure 11 The illustration shows an embodiment where the sewage discharge channel 310 includes an inner channel formed by a straight pipe 643 and a bend 615 sealed at one end, and the liquid replenishment channel 320 includes a second outer pipe 644 and a first outer pipe 616, forming an annular space between the straight pipe 643 and the bend 615. A first connector 611 may be located at the other end of the bend 615, and a second connector 612 may be located on the side wall of the first outer pipe 616.

[0121] With the above structure, regardless of the angle at which the adapter 610 is connected to the base station body 110 around the axis of the straight pipe 643, the straight pipe 643 and the bent pipe 615 are always sealed together, and the second outer pipe 644 and the first outer pipe 616 are always sealed together. This ensures that drainage and liquid replenishment can proceed normally without interference.

[0122] To ensure a good seal, a first sealing ring 650 can be provided between the straight pipe 643 and the bend 615. A second sealing ring 660 can be provided between the second outer pipe 644 and the first outer pipe 616. Besides using sealing rings, the straight pipe 643 and the bend 615, and / or the second outer pipe 644 and the first outer pipe 616 can also be sealed by an interference fit. In the illustrated embodiment, an axial sealing structure is used between the straight pipe 643 and the bend 615, and a radial sealing structure is used between the second outer pipe 644 and the first outer pipe 616. Optionally, a radial sealing structure can also be used between the straight pipe 643 and the bend 615. Optionally, an axial sealing structure can also be used between the second outer pipe 644 and the first outer pipe 616.

[0123] Furthermore, since the straight pipe 643 and the bent pipe 615 are interconnected to form an inner channel, the straight pipe 643 and the bent pipe 615 can extend to any length toward each other, as long as they can be sealed together. Specifically, refer to... Figure 11At the end of the bend 615 facing the straight pipe 643, the first outer pipe 616 is approximately connected to this end of the bend 615. This end of the bend 615 protrudes only a small portion from the connection between the bend 615 and the first outer pipe 616, approximately equal to the thickness of the first sealing ring 650. This arrangement is primarily to facilitate the insertion of the end of the straight pipe 643 into the gap between the bend 615 and the first outer pipe 616, pressing against the first sealing ring 650 to form a seal. If an axial seal were used between the straight pipe 643 and the bend 615, this end of the bend 615 might protrude further from the connection between the bend 615 and the first outer pipe 616. Axial sealing makes it easier to ensure the first sealing ring 650 is in the intended position during the installation of the adapter 610 to the drain rack 640 because the first sealing ring 650 does not move during installation, unlike radial sealing. Taking the radially sealed second sealing ring 660 as an example, although the second sealing ring 660 can be fixed by setting an annular groove on one of the first outer tube 616 or the second outer tube 644, if the outer diameter of the first outer tube 616 and the inner diameter of the second outer tube 644 are not significantly different, the second sealing ring 660 will still be pushed out of the annular groove during the installation of the adapter 610 onto the drain rack 640. For the first outer tube 616 and the second outer tube 644, they are located outside the straight tube 643 and the bend 615, making it easier to observe the second sealing ring 660 after the adapter 610 is installed onto the drain rack 640. However, for the first sealing ring 650, its position cannot be manually checked. Once the first sealing ring 650 is out of position, leakage may occur. Therefore, it is preferable to use an axial seal between the straight tube 643 and the bend 615. Of course, axial sealing can also be used for the first outer tube 616 and the second outer tube 644. For example, the second sealing ring 660 can be placed in the gap between the second outer tube 644 and the straight tube 643, so that the end of the second outer tube 644 is pressed against the second sealing ring 660 in the axial direction. However, this requires higher machining accuracy for the adapter 610 and the drain rack 640. Otherwise, it is possible that the end of the straight tube 643 is already pressed against the first sealing ring 650, while there is a gap between the end of the second outer tube 644 and the second sealing ring 660. The axial and radial directions mentioned above are relative to the straight tube 643.

[0124] For example, such as Figure 11As shown, when the first outer channel 614 and the second outer channel 642 form a joint liquid seal channel, a third connector 645 can be provided on the outer side of the second outer tube 644, and the third connector 645 is connected to the second outer channel 642. Since the inner channel formed by the straight pipe 643 and the bent pipe 615 is straight and has a large diameter, it can be used to form a sewage discharge channel 310, which is conducive to the discharge of garbage in the cleaning base station 100. The aforementioned annular space may have many bends, and the gap between the inner and outer walls of the annular space is usually small, otherwise it would result in an excessively large overall size. Therefore, it is more suitable to form a liquid seal channel 320 and connect it to a water source that supplies the liquid for liquid seal. The third connector 645 can be connected to the outlet of the tap water or the water tank in the cleaning base station 100 through a pipeline, and a separate pipeline can be set up to realize the function of liquid seal. If the drain channel 310 is used for liquid sealing, the drain pipe 620 has a large inner diameter, requiring a sufficient amount of water to overcome the aforementioned 0.5m height and deliver the liquid to the water pipe 700 for liquid sealing. This makes the liquid sealing process complex and energy-intensive. In contrast, the liquid sealing channel 320 can be connected to other water sources via the third connector 645, offering greater flexibility. To accommodate the narrower liquid sealing channel 320, the third connector 645 can be connected to a clean water source, preventing blockage. Furthermore, the annular space within the liquid sealing channel 320 allows for easy installation of the third connector 645 for connecting to a water source. Additionally, as mentioned earlier, the drain channel 310 is also used to connect to the fan 131 and discharge gaseous emissions, potentially resulting in significant noise levels within the drain channel 310. Enclosing the drain channel 310 with the annular liquid sealing channel 320 also helps to isolate noise.

[0125] For example, such as Figure 11 As shown, the first connector 611, the second connector 612, and / or the third connector 645 can be perpendicular to the straight pipe 643. Typically, the connector assembly 600 is located on the back of the cleaning base station 100, which is essentially placed against a fixed object, such as a wall. That is, the space between the back of the cleaning base station 100 and the wall is very limited. Furthermore, miniaturization of the cleaning base station 100 is a trend. In a user's home, the cleaning base station 100 may be placed in a cabinet; therefore, reducing the thickness of the base station body 110 of the cleaning base station 100 allows for greater installation freedom and does not occupy a large amount of space. The first connector 611, the second connector 612, and / or the third connector 645 being perpendicular to the straight pipe 643 eliminates the need to increase the gap between the wall and the cleaning base station 100 or to thicken the cleaning base station 100 after they are connected to the corresponding pipe bodies. It also reduces the bending of the connected pipe bodies.

[0126] For example, the third connector 645 can be installed inside the base station body 110 of the cleaning base station 100. The third connector 645 is connected to a water supply pipe located inside the base station body 110 of the cleaning base station 100. This water supply pipe is used to connect to a water source 900 (including municipal water). In this way, from the outside, this improved cleaning base station 100 is almost indistinguishable from a regular cleaning base station 100, with a simple appearance and a better user experience. This pipe inside the base station body 110 can be connected to a water source inside the base station body 110, or to a municipal water source, or both. The advantage of using the water source inside the base station body 110 to repair the damaged liquid seal is that, even during a water outage, the water tank in the base station body 110 can still be used to replenish liquid to the drain to repair the damaged liquid seal. The advantage of using a municipal water source to repair the damaged liquid seal is that, even when there is no water tank or other water source inside the base station body 110, the cleaning base station 100 can still have the function of replenishing the liquid seal.

[0127] For example, such as Figure 15 As shown, the sewage rack 640 also has a sewage rack inlet 647 connected to the sewage outlet 112. The second central channel 641 can be connected to the sewage rack inlet 647. An installation cavity can be provided between the sewage rack inlet 647 and the second central channel 641, and a third one-way valve 670 can be installed in the installation cavity. The third one-way valve 670 can be configured to be closed under normal conditions and open under the action of sewage discharged from the base station body 110. Thus, when the base station body 110 discharges sewage or gaseous emissions, the third one-way valve 670 can be automatically opened, and when the sewage or gaseous emissions are completed, the third one-way valve 670 can be automatically closed. This prevents sewage in the downstream sewage pipe 620 from flowing back into the base station body 110.

[0128] For example, such as Figure 12 and 14As shown, the adapter 610 is detachably connected to the drain rack 640 via a snap fastener 617. Exemplarily, the snap fasteners 617 are symmetrically arranged vertically on the adapter 610, allowing the adapter 610 to be mounted on the drain rack 640, and remaining fixed to the base station body 110 even after the adapter 610's angle relative to the base station body 110 is adjusted. When it is necessary to remove the adapter 610, it can be unlocked and removed by pressing the long handle of the snap fastener 617. The snap fastener 617 can be located on the adapter 610. The adapter 610 is closer to the outside of the base station body 110 than the drain rack 640, making it easier to operate. Correspondingly, the drain rack 640 can be provided with a snap fastener adapter 649 that engages with the snap fastener 617. In other embodiments not shown, the snap fastener 617 can be located on the drain rack 640. In the illustrated embodiment, the snap fastener adapter 649 is a through opening. In other embodiments not shown, the snap-fit ​​adapter 649 may be a groove or a blind hole, etc. Exemplarily, a limiting portion 648 may be provided on the drain rack 640. The limiting portion 648 protrudes outward toward the base station body 110. The limiting portion 648 can limit the adapter 610 mounted on the drain rack 640, ensuring a reliable and stable connection between the adapter 610 and the drain rack 640. The adapter 610 is inserted into the space surrounded by the limiting portion 648. In the illustrated embodiment, the limiting portion 648 includes a pair of opposing limiting posts. In other embodiments not shown, the limiting portion 648 may include one or more of the following: a ring structure, a mesh structure, a plurality of discrete protrusions distributed around the drain rack 640, etc. When the limiting part 648 includes multiple limiting posts, the spacing between the limiting posts allows them to have a certain gap, enabling them to slightly open to accommodate the size of the adapter 610 and apply a certain external force to the adapter 610, thereby ensuring a reliable connection between the adapter 610 and the drain rack 640. To allow the latch 617 to be closer to the outside, a latch adapter 649 that mates with the latch 617 can be provided on the limiting part 648.

[0129] According to a second aspect of this application, a liquid sealing device is provided. The liquid sealing device is applied to a cleaning base station 100, that is, the liquid sealing device is used in conjunction with the cleaning base station 100. The cleaning base station 100 includes a sewage discharge channel 310, which is connected to a floor drain for discharging at least some gaseous emissions into the floor drain. (See also: [link to relevant documentation]) Figure 4The liquid seal device may include a liquid seal channel 320, an execution component, and a control component. The liquid seal channel 320 may communicate with a floor drain 500 for supplying liquid to the floor drain 500. The execution component controls the liquid supply. The control component, after the gas emissions are discharged, drives the execution component to supply liquid to the floor drain 500 to establish a liquid seal in the drain pipe 700 connected to the floor drain 500. Using the liquid seal device provided in this application, after the internal gas is discharged into the drain pipe 700, the liquid seal device can repair the damaged liquid seal 800 in the drain pipe 700, preventing odors or bacteria from the drain pipe 700 from flowing back into the user's home. In this embodiment, the liquid seal device is installed independently of the cleaning base station 100 and can be sold separately. The liquid seal device can communicate and cooperate with the cleaning base station 100; for example, when liquid seal replenishment is needed, the liquid seal device is controlled to replenish liquid in the drain pipe 700.

[0130] According to a third aspect of this application, a cleaning system is provided. The cleaning system may include a cleaning device 200 and any of the cleaning base stations 100 described above, or the cleaning system may include a cleaning device 200 and such... Figure 4 The base station and liquid sealing device shown are referenced in the previous section. Figure 1-4 The cleaning device 200 may optionally interface with the cleaning base station 100. The cleaning base station 100 may provide power to the cleaning device 200 and / or provide a drainage channel for discharging waste from the cleaning device 200. For example, the cleaning device 200 may include a dust collection container 210. When the cleaning device 200 interfaces with the cleaning base station 100, the outlet of the dust collection container 210 is connected to the discharge channel 300. Optionally, the cleaning base station 100 may include a waste storage device 120, through which the outlet of the dust collection container 210 can be connected to the discharge channel 300. The waste storage device 120 may store solid waste (including dry or wet waste) from the dust collection container 210. Optionally, the outlet of the dust collection container 210 may be directly connected to the discharge channel 300, allowing waste from the dust collection container 210 to be directly discharged into the drain 500 via the discharge channel 300.

[0131] According to a fourth aspect of this application, a control method for cleaning base stations is provided. For example... Figure 19 As shown, the control method may include a drying step S10, which dries the garbage stored in the garbage storage device of the cleaning base station and discharges the gas emissions generated during the drying process into the floor drain.

[0132] After the drying step S10 is completed, the sealing step S20 can be performed. After drying, liquid is supplied to the floor drain to establish a liquid seal in the drain pipe connected to the floor drain. Exemplarily, the sealing step S10 includes supplying a preset amount of liquid to the floor drain to ensure an effective liquid seal is established while avoiding resource waste. In one set of embodiments, the sealing step S20 may specifically include: starting a timer from the moment liquid is supplied to the floor drain, and stopping the discharge of liquid when the timer reaches a preset time, so that the preset amount of liquid is supplied to the floor drain. In another set of embodiments, the sealing step S20 may specifically include: detecting the liquid supply flow rate; determining the total liquid supply based on the supply flow rate; and stopping the liquid supply when the total supply reaches a preset amount. Thus, the preset amount of liquid can be supplied to the floor drain to re-establish a liquid seal in the drain pipe connected to the floor drain.

[0133] The process includes a filtration step S01 prior to the drying step S10, which receives dirt from the cleaning equipment and filters out wet waste from the dirt, allowing wastewater to be discharged into a floor drain. Exemplarily, the drying step S10 specifically includes using a fan to dry the wet waste to generate the gaseous emissions.

[0134] The following is based on Figure 1-4 and Figure 19 Taking the illustrated embodiment as an example, the control method for the cleaning base station 100 will be described in detail. In this embodiment, a first one-way valve 141 is provided on the first pipe 140 between the sewage inlet 111 of the cleaning base station 100 and the first connection port 1211 of the waste storage device 120, and a second one-way valve 151 is provided on the second pipe 150 between the fan 131 and the first connection port 1211 of the waste storage device 120.

[0135] When a cleaning device 200 connects to a cleaning base station 100, and waste enters the waste storage device 120 from the dust collection container 210 of the cleaning device 200 via the waste inlet 111, the cleaning base station 100 can perform the filtration step S01. For example, the user can press a self-cleaning button to initiate the filtration step S01. In this way, the weight of the waste itself can open the second one-way valve 151, allowing the waste to move through the second pipe 150 to the first connection port 1211 and into the storage compartment 121 of the waste storage device 120. After a first predetermined time, all the waste discharged by the cleaning device 200 into the waste inlet 111 enters the storage compartment 121 through the second pipe 150. This first predetermined time is related to the maximum waste capacity of the cleaning device 200. For example, if the maximum amount of waste the cleaning device 200 can carry is known, and it takes 20 seconds for all of this waste to enter the storage compartment 121 through the waste inlet 111, then the first predetermined time can be set to 20 seconds. Obviously, the first predetermined time for cleaning base station 100 can also be set by the user according to actual needs, which will not be elaborated here. After the filtration step S01, the waste is divided into two categories. One category is larger solid waste (including one or more of dry waste and wet waste), which is stored in the waste storage device 120. The other category is sewage, which can be discharged into the drain 500 through the discharge channel 300.

[0136] Exemplarily, the control method may further include a drainage step S02. After a first predetermined time, the cleaning base station 100 executes the filtration step S01 and then executes a first operation command. In response to the first operation command, the cleaning base station 100 begins to execute the drainage step S02. After the first predetermined time, due to the lack of dirt in the second pipe 150, the second one-way valve 151 switches to the closed state. In response to the first operation command, the control component controls the fan 131 to start and enter a first operating state. The first operating state of the fan 131 may be that the fan 131 is in a full duty cycle state, at which time the fan 131 intakes air at a large flow rate, and the resulting airflow causes the first one-way valve 141 to open. The airflow enters the storage chamber 121 through the first pipe 140, causing positive pressure to be generated in the storage chamber 121. The wastewater formed by filtration in the storage chamber 121 will be discharged to the outside more quickly through the drain port 112. When the blower 131, in its first operating state, creates positive pressure within the storage chamber 121, this positive pressure allows wastewater to move along the discharge channel 300 to a height of 0.5m to the outside, thus addressing any upward bends in the discharge channel 300. Figure 16As shown. Furthermore, in common application environments of the cleaning base station 100, the waste discharged from the discharge channel 300 can typically be directly discharged into the floor drain 500 in the user's home, or it can be discharged into the floor drain 500 in the user's home through an external pipe connected to the discharge channel 300. When the fan 131 creates positive pressure inside the storage chamber 121, under the action of positive pressure, the airflow discharged from the drain port 112 can break through the liquid seal 800 in the drain pipe 700, thereby allowing the odor in the storage chamber 121 to be discharged through the drain port 112 to the floor drain 500, and then discharged to the outside through the floor drain 500.

[0137] After a second predetermined time has elapsed following the drainage step S02, the cleaning base station 100 executes the second operation command. The second predetermined time can be the time required for all the sewage of the maximum sewage capacity in the storage compartment 121 of the cleaning base station 100 to be discharged to the outside through the drain outlet 112. For example, if it takes 20 seconds for all the sewage of the maximum sewage capacity in the storage compartment 121 to be discharged to the outside through the drain outlet 112, then the second predetermined time is 20 seconds.

[0138] In response to the second operation command, the cleaning base station 100 begins to execute the drying step S10. At this time, the fan 131 is adjusted to a second operating state, which can be a low duty cycle state. Although the air volume of the fan 131 is reduced, the first one-way valve 141 remains open. Simultaneously, the control heater 132 is turned on, causing the airflow generated by the fan 131 to heat up, thereby raising the air in the storage chamber 121 to a certain temperature to dry the wet waste formed by filtration. For example, the heater 132 can raise the air in the storage chamber 121 to 55°C for drying.

[0139] After the drying step S10 is completed by the cleaning base station 100, a third operation command is executed after a third predetermined time. The third predetermined time can be the longest time required for the wet waste in the storage compartment 121 to be dried. After the drying step S10 is completed after the third predetermined time, in response to the third operation command, the fan 131 and the heater 132 are controlled to shut down. The first one-way valve 141 and the second one-way valve 151 are both in the closed state, so odors and bacteria cannot leak from the inlet 111 and the fan 131 to the external environment, and the wet waste in the storage compartment 121 will no longer produce odors after drying.

[0140] In response to the third operation command, the cleaning base station 100 begins the resealing step S20. By controlling the duration of liquid supply to the drain pipe 700 connected to the drain 500 or detecting the liquid supply flow rate, a predetermined amount of liquid can be discharged into the drain pipe 700 to re-establish the liquid seal 800 in the drain pipe 700. The original liquid seal in the drain 500 was destroyed in the drainage step S02 and the drying step S10. Since the drain 500 also needs to be connected to the external environment, if the liquid seal is not re-established, odors in the drain pipe may diffuse into the external environment through the drain 500.

[0141] The control method provided in this application not only ensures that the cleaning base station 100 can smoothly discharge garbage, but also repairs the liquid seal 800 in the sewer pipe 700 that is damaged during the entire sewage discharge process, thus preventing the odor and bacteria in the sewer pipe 700 from spreading to the external environment.
