Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning system. Background Technology

[0002] Currently, after cleaning equipment completes its floor cleaning and self-cleaning tasks, residual moisture remains inside the wastewater tank, making the tank quite damp. This damp environment easily breeds bacteria, which in turn produces foul-smelling gases such as NH3, H2S, and organic acids. As a result, the wastewater tank will smell bad the next time it is used, greatly reducing the user experience. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a cleaning system that can solve the problem of severe odor from sewage tanks.

[0004] The cleaning system according to a first aspect of the present invention includes a cleaning device, a cleaning base station, and an air-driven component. The cleaning device includes a wastewater tank having an openable and closable discharge port. The cleaning base station includes a docking position for the cleaning device to dock, and the discharge port for receiving waste discharged from the discharge port. The air-driven component includes a first air-driven component disposed on the cleaning device and / or a second air-driven component disposed on the cleaning base station.

[0005] When the cleaning equipment is parked at the parking position and the drain outlet is open, the drain outlet and the sewage inlet are in corresponding and connected positions, and the air drive unit is adapted to drive air from the drain outlet into the sewage tank.

[0006] According to the cleaning system of this utility model embodiment, when the cleaning equipment is parked in the parking position, by connecting the drain port and the collection port, after the sewage in the sewage tank is discharged, the air drive component drives air to enter the inside of the sewage tank from the drain port, which accelerates the evaporation of water in the sewage tank and achieves the purpose of drying the inner wall of the sewage tank. This avoids the sewage tank being in a high humidity environment for a long time, reduces the probability of microorganisms growing inside the sewage tank and producing foul-smelling gases such as NH3, H2S, and organic acids, and helps to improve the user experience.

[0007] In some embodiments, the cleaning base station further includes a drying air duct, the dirt collection port is connected to the drying air duct, and a heating element is provided in the drying air duct for heating the air in the drying air duct.

[0008] When the cleaning equipment is parked at the parking position and the drain outlet is open, the drain outlet and the wastewater collection port are in corresponding and connected positions. The air drive unit is adapted to drive the hot air formed in the drying air duct through the wastewater collection port and into the wastewater tank from the drain outlet.

[0009] In some specific embodiments, when the cleaning equipment is parked in the parking position, the drain outlet and the receiving outlet are sealed together, or the size of the drain outlet is smaller than the size of the receiving outlet and the projection of the drain outlet onto the plane of the receiving outlet is located within the receiving outlet.

[0010] In some specific embodiments, the sewage outlet is equipped with a switch door. The cleaning base station includes a switch door drive mechanism, which, when the cleaning equipment is docked at the docking position, is used to open or close the switch door to open or close the sewage outlet.

[0011] In some examples, the cleaning base station also includes a sewage discharge channel with a drain outlet for discharging sewage from the channel. The sewage discharge channel connects the sewage receiving port, the drain outlet, and the drying air duct.

[0012] In some specific examples, the sewage discharge channel is equipped with a solid-liquid separation chamber and / or a filter screen, which is used to separate the sewage entering the sewage discharge channel into solid and liquid phases, and discharge the separated sewage from the drain outlet.

[0013] In some specific examples, the lower end of the drying duct is connected to the lower side wall of the sewage discharge channel, and there is a gap between the bottom of the solid-liquid separation chamber and / or the filter screen and the bottom wall of the sewage discharge channel.

[0014] The bottom wall of the drying duct and the bottom wall of the sewage discharge channel have a guide surface to guide the hot air in the drying duct from the bottom wall of the solid-liquid separation chamber and / or the filter screen through the solid-liquid separation chamber and / or the filter screen.

[0015] In some embodiments, when the cleaning equipment is parked at the parking position and the drain outlet is open, the drain outlet and the wastewater inlet are positioned correspondingly and connected. The air drive unit causes the hot air generated in the drying duct to pass through the drain channel and the wastewater inlet, and then enter the wastewater tank from the drain outlet.

[0016] In some specific embodiments, the second air drive component is disposed in the drying air duct, and the height of the second air drive component and the heating component is higher than the first water level of the sewage discharge channel and the drying air duct. The first water level is the water level discharged into the sewage discharge channel and the drying air duct when the sewage tank is full.

[0017] In some embodiments, the second air drive member and the heating member are positioned at a height higher than the sewage inlet.

[0018] In some embodiments, the cleaning base station further includes an in-situ detection device for detecting the in-situ status of the cleaning equipment at the docking position. When the cleaning equipment leaves the docking position, the cleaning base station controls the second air drive unit and the heating unit to stop working.

[0019] In some examples, the cleaning base station further includes a first humidity detection device for detecting the humidity in the drying duct and / or the sewage discharge channel. If the humidity in the drying duct and / or the sewage discharge channel is lower than a first preset value, the air drive and the heating element are controlled to stop working.

[0020] In some examples, the cleaning device further includes a second humidity detector for detecting the humidity inside the wastewater tank. If the humidity inside the wastewater tank is lower than a second preset value, the air drive and the heating element are controlled to stop working.

[0021] A cleaning system according to a second aspect of the present invention includes a cleaning device, a cleaning base station, and a first air-driven component. The cleaning device includes a wastewater tank with an openable and closable drain outlet. The first air-driven component is disposed on the cleaning device. When the cleaning device is in a self-drying state, the first air-driven component is adapted to drive external air into the wastewater tank from the drain outlet.

[0022] According to the cleaning system of this utility model embodiment, by setting a first air driving component on the cleaning equipment, air can be driven to enter the sewage tank from the drain port and then flow out of the sewage tank from the top of the sewage tank. This can accelerate the evaporation of water inside the sewage tank and realize the air drying process of the sewage tank. This avoids the growth of microorganisms in the sewage tank due to excessive humidity and prevents the generation of odor from the source.

[0023] In some embodiments, the cleaning device further includes a third humidity detector for detecting the humidity inside the wastewater tank. If the humidity inside the wastewater tank is lower than a third preset value, the first air drive unit is controlled to stop working.

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-11 A cleaning system 100 according to an embodiment of the present invention is described.

[0029] Reference Figures 1-4 The cleaning system 100 according to an embodiment of the present invention includes a cleaning device 10. The cleaning device 10 includes a wastewater tank 11, which has an openable and closable drain outlet 11a through which wastewater in the wastewater tank 11 can be discharged.

[0030] The cleaning system 100 also includes a cleaning base station 20, which includes a docking position 20a and a waste collection port 20b. The docking position 20a is used for the cleaning equipment 10 to dock, and the waste collection port 20b is used to collect the waste discharged from the waste discharge port 11a.

[0031] The parking space 20a is a specific area designed specifically for the cleaning equipment 10. This area can be a region on the cleaning base station 20 used to place or accommodate the cleaning equipment 10, or it can be an area located on one side of the cleaning base station 20. By setting up the parking space 20a, users can place the cleaning equipment 10 on the parking space 20a, avoiding space occupation, collision damage, and obstruction of passage caused by haphazard placement of the cleaning equipment 10. On the other hand, the cleaning equipment 10 can be placed on the parking space 20a and connected to the cleaning base station 20, facilitating operations such as charging, maintenance, and cleaning of the cleaning equipment 10.

[0032] After using the cleaning equipment 10, the user can place the cleaning equipment 10 in the parking position 20a of the cleaning base station 20, so that the sewage outlet 11a is connected to the sewage receiving outlet 20b. In this way, the sewage in the sewage tank 11 can be discharged from the sewage tank 11 through the sewage outlet 11a and enter the cleaning base station 20 through the sewage receiving outlet 20b, thereby completing the sewage discharge of the cleaning equipment 10.

[0033] Reference Figure 1 and Figure 2The cleaning system 100 also includes an air drive 25, which includes a first air drive 251 and / or a second air drive 252. The first air drive 251 is disposed in the cleaning device 10, and the second air drive 252 is disposed in the cleaning base station 20.

[0034] When the cleaning equipment 10 is parked at the parking position 20a and the drain port 11a is open, the drain port 11a and the sewage inlet 20b are in corresponding positions and connected. The air drive unit 25 is adapted to drive air from the drain port 11a into the sewage tank 11 to dry the sewage tank 11.

[0035] For example, the air drive 25 may include a first air drive 251 disposed on the cleaning device 10. When the cleaning device 10 performs a cleaning task, the first air drive 251 can suck the dirt on the surface to be cleaned into the wastewater tank 11. After the cleaning device 10 completes the cleaning task, it can dock at the docking position 20a of the cleaning base station 20. After the wastewater in the wastewater tank 11 is discharged, the first air drive 251 can be activated to drive the air to form an airflow, so that the air enters the interior of the wastewater tank 11 from the drain port 11a. This can accelerate the evaporation of moisture inside the wastewater tank 11 and achieve the purpose of drying the wastewater tank 11.

[0036] For example, the air drive 25 may include a second air drive 252 disposed at the cleaning base station 20. After the cleaning equipment 10 completes the cleaning task, it can dock at the docking position 20a of the cleaning base station 20. After the sewage in the sewage tank 11 is discharged, the second air drive 252 can be activated to drive the air to form an airflow, so that the air flows through the sewage inlet 20b and the sewage outlet 11a in sequence and enters the sewage tank 11. This can accelerate the evaporation of water in the sewage tank 11 and achieve the purpose of drying the sewage tank 11.

[0037] For example, the air drive unit 25 may include a first air drive unit 251 disposed on the cleaning device 10 and a second air drive unit 252 disposed on the cleaning base station 20. After the cleaning device 10 completes the cleaning task, it can dock at the docking position 20a of the cleaning base station 20. After the sewage in the sewage tank 11 is discharged, the first air drive unit 251 and the second air drive unit 252 can be activated. At the same time, the first air drive unit 251 and the second air drive unit 252 are used to drive the air to form an airflow, so that more air enters the sewage tank 11, greatly accelerating the evaporation rate of the water inside the sewage tank 11 and drying the sewage tank 11 faster.

[0038] According to the cleaning system 100 of this utility model embodiment, when the cleaning device 10 is parked at the parking position 20a, by connecting the drain port 11a and the sewage inlet 20b, after the sewage in the sewage tank 11 is discharged, the air drive component 25 drives air to enter the interior of the sewage tank 11 from the drain port 11a, which accelerates the evaporation of moisture in the sewage tank 11 and achieves the purpose of drying the inner wall of the sewage tank 11. This avoids the sewage tank 11 being in a high humidity environment for a long time, reduces the probability of microorganisms growing inside the sewage tank 11 and producing odorous gases such as NH3, H2S, and organic acids, and helps to improve the user experience.

[0039] Reference Figure 7 and Figure 8 In some embodiments, the cleaning base station 20 further includes a drying air duct 21, the dirt collection port 20b is connected to the drying air duct 21, and a heating element 211 is provided in the drying air duct 21 for heating the air in the drying air duct 21.

[0040] When the cleaning equipment 10 is parked at the parking position 20a and the drain port 11a is open, the drain port 11a and the receiving port 20b are in corresponding positions and connected. The air drive unit 25 is adapted to drive the hot air formed in the drying air duct 21 through the receiving port 20b and into the sewage tank 11 from the drain port 11a.

[0041] Specifically, when the cleaning equipment 10 is parked at the parking position 20a of the cleaning base station 20, the sewage outlet 11a is opened, so that the sewage tank 11 and the drying air duct 21 are connected through the sewage outlet 11a and the sewage receiving outlet 20b.

[0042] If the first air drive unit 251 installed in the cleaning equipment 10 is started, the first air drive unit 251 can drive air into the drying air duct 21. During this process, the heating unit 211 can heat the air in the drying air duct 21, thereby forming hot air in the drying air duct 21. The hot air passes through the sewage receiving port 20b and the sewage discharge port 11a in sequence, and finally enters the sewage tank 11 to dry the sewage tank 11.

[0043] If the second air drive unit 252 installed on the cleaning base station 20 is activated, the second air drive unit 252 can drive air into the drying air duct 21. During this process, this part of the air will pass through the heating element 211. After being heated by the heating element 211, it will form hot air. The hot air passes through the sewage receiving port 20b and the sewage discharge port 11a in sequence from the drying air duct 21, and finally enters the sewage tank 11 to dry the sewage tank 11.

[0044] If the first air drive unit 251 installed on the cleaning equipment 10 and the second air drive unit 252 installed on the cleaning base station 20 are started at the same time, the second air drive unit 252 can drive air into the drying air duct 21. During this process, this part of the air will pass through the heating element 211 and become hot air after being heated by the heating element 211. The hot air passes through the sewage receiving port 20b and the sewage discharge port 11a in sequence from the drying air duct 21. At the same time, the first air drive unit 251 can provide assistance to the hot air, driving the hot air to enter the sewage tank 11 more quickly and dry the sewage tank 11.

[0045] Therefore, in the above technical solution, by setting a drying air duct 21 in the cleaning base station 20 and setting a heating element 211 in the drying air duct 21, hot air can be generated in the drying air duct 21. In this way, the hot air can be transported to the sewage tank 11 by the air drive element 25, thereby accelerating the evaporation of water in the sewage tank 11 and improving the drying speed of the sewage tank 11.

[0046] Reference Figure 3 In some specific embodiments, when the cleaning equipment 10 is parked in the parking position 20a, the drain port 11a and the receiving port 20b are sealed together.

[0047] This design, on the one hand, prevents sewage leakage during the sewage discharge process of the sewage tank 11, which is beneficial to improving the user experience. On the other hand, in the embodiment with drying air duct 21 and heating element 211, when drying the sewage tank 11, hot air can be prevented from flowing to the outside through the gap between the sewage outlet 11a and the sewage receiving outlet 20b, reducing the heat loss of hot air and allowing hot air to flow into the sewage tank 11 as much as possible, which is beneficial to improving the drying efficiency of the sewage tank 11.

[0048] Reference Figure 4 In some other specific embodiments, when the cleaning equipment 10 is parked at the parking position 20a, the size of the drain outlet 11a is smaller than the size of the receiving outlet 20b, and the projection of the drain outlet 11a onto the plane where the receiving outlet 20b is located is within the receiving outlet 20b.

[0049] This configuration creates an air intake gap between the sewage inlet 20b and the sewage outlet 11a. When the air drive unit 25 drives air into the sewage tank 11, external air near the sewage outlet 11a can enter the sewage tank 11 from here, thereby increasing the drying speed of the sewage tank 11.

[0050] Furthermore, in embodiments with drying duct 21 and heating element 211, although some hot air may leak out when the hot air from drying duct 21 flows through it, the air drive element 25 can also drive external air to flow into the wastewater tank 11 from the air inlet gap, thereby increasing the amount of air flowing into the wastewater tank 11 and improving the drying speed of the wastewater tank 11 to a certain extent.

[0051] Reference Figure 3 In some specific embodiments, the drain outlet 11a is provided with a switch door 11a1.

[0052] The cleaning base station 20 includes a door opening and closing drive unit 22. When the cleaning equipment 10 is parked in the parking position 20a, the door opening and closing drive unit 22 is used to open or close the door 11a1 so that the sewage outlet 11a is opened or closed.

[0053] In the above technical solution, by setting a switch door 11a1 at the sewage outlet 11a and setting a switch door drive component 22 on the cleaning base station 20, the switch door drive component 22 can be used to control the opening and closing of the switch door 11a1, thereby realizing the opening and closing of the sewage outlet 11a. When the cleaning equipment 10 performs cleaning tasks, or after the sewage tank 11 is dried, the sewage outlet 11a can be closed to avoid sewage leakage and prevent foreign objects or water from entering the sewage tank 11. When sewage needs to be discharged or the sewage tank 11 needs to be dried, the sewage outlet 11a can be opened to facilitate the discharge of sewage from the sewage tank 11 and the drying of the sewage tank 11, thereby improving the convenience of the cleaning system 100.

[0054] For example, the door opening / closing drive 22 may include a first drive unit 221 and a second drive unit 222. Both the first drive unit 221 and the second drive unit 222 can be connected to the door opening / closing 11a1. The first drive unit 221 opens the door opening / closing 11a1 by triggering the triggering part of the door opening / closing 11a, thereby opening the drain outlet 11a. The second drive unit 222 closes the door opening / closing 11a1 by pushing the door opening / closing 11a1, thereby closing the drain outlet 11a.

[0055] When the cleaning equipment 10 is performing a cleaning task, the door 11a1 is in the closed state, which can seal the sewage tank 11 and prevent sewage leakage from the inside of the sewage tank 11.

[0056] After the cleaning equipment 10 completes the cleaning task, the cleaning equipment 10 stops at the stopping position 20a. Under the action of the first drive unit 221, the opening and closing door 11a1 is opened, and the sewage in the sewage tank 11 can be discharged from the drain port 11a. Subsequently, the air drive unit 25 can be used to drive air to dry or bake the sewage tank 11. After the drying or baking is completed, the opening and closing door 11a1 can be closed by the second drive unit 222 to seal the sewage tank 11 again, which can prevent foreign objects or moisture from entering the sewage tank 11.

[0057] For example, the door opening / closing drive 22 may include components such as gears and racks.

[0058] Reference Figure 1 , Figures 5-7 In some examples, the cleaning base station 20 also includes a sewage discharge channel 23, which is provided with a sewage outlet 23a for discharging sewage from the sewage discharge channel 23. The sewage discharge channel 23 connects the sewage receiving outlet 20b, the sewage outlet 23a and the drying air duct 21.

[0059] When sewage is discharged from sewage tank 11, the sewage enters sewage discharge channel 23 through sewage inlet 20b. Sewage often carries solid waste. At this time, sewage and waste are temporarily stored in sewage discharge channel 23 and can be discharged from sewage discharge channel 23 through sewage outlet 23a later.

[0060] When drying the wastewater tank 11, since the sewage discharge channel 23 connects the sewage receiving port 20b and the drying air duct 21, the second air drive unit 252 can drive air from the drying air duct 21 into the sewage discharge channel 23, and then sequentially through the sewage receiving port 20b and the sewage discharge port 11a into the wastewater tank 11.

[0061] In the above technical solution, by setting up a sewage discharge channel 23 in the clean base station 20, the sewage discharge channel 23 connects the sewage receiving port 20b, the drying air duct 21 and the sewage discharge port 23a. On the one hand, the sewage and dirt temporarily stored in the sewage discharge channel 23 can be discharged from the sewage discharge port 23a. On the other hand, it provides a path for air to reach the sewage tank 11, so that the second air drive component 252 can drive hot air to flow through the sewage discharge channel 23 and the sewage tank 11 in sequence. This facilitates the drying of the sewage discharge channel 23 and the sewage tank 11 by hot air, avoids the sewage discharge channel 23 and the sewage tank 11 being in a high humidity environment for a long time, reduces the probability of microorganisms growing inside the sewage discharge channel 23 and the sewage tank 11 and producing odorous gases such as NH3, H2S and organic acids, and helps to improve the user experience.

[0062] Refer again Figure 7 and Figure 9 In some specific examples, the sewage channel 23 is provided with a solid-liquid separation chamber 231 and / or a filter screen 232. The solid-liquid separation chamber 231 and / or the filter screen 232 are used to separate the sewage entering the sewage channel 23 into solid and liquid components, and discharge the separated sewage from the drain outlet 23a.

[0063] For example, the sewage discharge channel 23 is equipped with a solid-liquid separation chamber 231, which is a rigid structure with densely packed small holes. After sewage containing contaminants enters the solid-liquid separation chamber 231, the solid contaminants carried by the sewage are blocked by the small holes and remain in the solid-liquid separation chamber 231, while the sewage continues to flow into the sewage discharge channel 23 through the small holes on the solid-liquid separation chamber 231. When the hot air driven by the second air drive 252 flows through the sewage discharge channel 23, it can dry the contaminants in the solid-liquid separation chamber 231, making it easier to remove the contaminants later.

[0064] For example, a filter screen 232 with dense pores is provided in the sewage discharge channel 23. After sewage containing dirt enters the filter screen 232, the solid dirt carried by the sewage is blocked by the pores and remains in the filter screen 232, while the sewage continues to flow into the sewage discharge channel 23 through the pores on the filter screen 232.

[0065] The filter screen 232 can be a flexible component with dense pores, such as a flexible mesh bag. When hot air driven by the second air drive 252 flows through the drain channel 23, it dries the dirt inside the filter screen 232, making it easier to remove and empty the dirt. The filter screen 232 can also be a consumable; after the drying process, the filter screen 232 containing solid dirt can be discarded and replaced with a new one, thus eliminating the need for cleaning the filter screen 232 and providing convenience for the user.

[0066] For example, the sewage discharge channel 23 can be equipped with both a solid-liquid separation chamber 231 and a filter screen 232. The filter screen 232 is installed on the solid-liquid separation chamber 231. When sewage containing contaminants enters the filter screen 232, the solid contaminants carried by the sewage are blocked by small holes and remain inside the filter screen 232. The sewage then flows into the sewage discharge channel 23 through the small holes on the filter screen 232 and the solid-liquid separation chamber 231. After the drying process is completed, the filter screen 232 can be directly discarded and replaced with a new one, thus achieving the cleaning of solid contaminants and eliminating the need for cleaning the filter screen 232, providing convenience for the user.

[0067] In addition, placing the filter screen 232 on the solid-liquid separation chamber 231 can also support and restrict the filter screen 232, preventing excessive solid dirt in the filter screen 232 from causing the filter screen 232 to droop down to the drain port 23a and thus causing the drain port 23a to become blocked.

[0068] In the above technical solution, by setting a solid-liquid separation chamber 231 and / or filter screen 232 in the sewage discharge channel 23, the sewage entering the sewage discharge channel 23 can be separated into solid and liquid. In this way, solid sewage can be retained in the solid-liquid separation chamber 231 and / or filter screen 232, which can prevent solid sewage from clogging the sewage outlet 23a, cleaning the internal pipes of the base station 20 and the sewer during subsequent use, and can also prevent the accumulation of solid sewage, which would cause inconvenience in cleaning.

[0069] Reference Figure 1 , Figure 5 and Figure 6 In some examples, a sewage tank 24 is also provided below the sewage discharge channel 23 of the cleaning base station 20. The sewage tank 24 is provided with an inlet 241 and an outlet 242. The inlet 241 is connected to the sewage discharge outlet 23a, and the outlet 242 is connected to the sewer. The sewage after solid-liquid separation can flow to the sewage discharge channel 23 for temporary storage. When the inlet 241 is opened, the sewage in the sewage discharge channel 23 can enter the sewage tank 24 in sequence through the sewage discharge outlet 23a and the inlet 241.

[0070] The sewage tank 24 is equipped with an air pump (not shown in the figure) and a ventilation valve 243. The air pump can pressurize the sewage tank 24 to increase the air pressure inside, and it can also extract air from the sewage tank 24 to decrease the air pressure inside. The ventilation valve 243 may include a first valve body and a second valve body. The first valve body can control the connection between the sewage tank 24 and the sewage discharge channel 23, and the second valve body can control the connection between the sewage tank 24 and the sewer.

[0071] Specifically, when the wastewater after solid-liquid separation is discharged from the sewage discharge channel 23 into the wastewater tank 24, the first valve body controls the wastewater tank 24 to be connected to the sewage discharge channel 23, and the second valve body controls the wastewater tank 24 to be disconnected from the sewer. That is, at this time, the inlet 241 is opened and the outlet 242 is closed. The air pump draws gas from the wastewater tank 24, thereby reducing the air pressure in the wastewater tank 24. At this time, the air pressure in the wastewater tank 24 is less than the air pressure in the sewage discharge channel 23. Under the action of the pressure difference, the wastewater can be forced to enter the wastewater tank 24.

[0072] When it is necessary to drain the sewage tank 24, the first valve body controls the sewage tank 24 to disconnect from the sewage discharge channel 23, and the second valve body controls the sewage tank 24 to connect with the sewer, that is, the inlet 241 is closed and the outlet 242 is opened. The air pump inflates the sewage tank 24, thereby increasing the air pressure in the sewage tank 24. Under the action of the pressure difference, the sewage in the sewage tank 24 is discharged into the sewer from the outlet 242.

[0073] By configuring the sewage discharge channel 23 to include a solid-liquid separation chamber 231 and / or a filter screen 232, the sewage entering the sewage discharge channel 23 can be separated into solid and liquid components. The waste remains in the solid-liquid separation chamber 231 and / or the filter screen 232. When hot air driven by the second air drive 252 flows through this area, it can dry the waste, making it easier to remove the waste later. At the same time, the sewage flows into the sewage tank 24. By setting an air pump and an air exchange valve 243, the pressure in the sewage tank 24 can be changed, which greatly improves the sewage discharge speed. On the other hand, it solves the problem of drainage difficulties caused by the many bends in household pipes.

[0074] Reference Figure 1 , Figure 7 , Figure 9 and Figure 10 In some specific examples, the lower end of the drying duct 21 is connected to the lower side wall of the drain channel 23, and there is a gap between the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232 and the bottom wall of the drain channel 23.

[0075] Here, "the lower end of the drying duct 21" refers to the end of the drying duct 21 near the bottom of the cleaning base station 20, and "the lower part of the side wall of the sewage discharge channel 23" refers to the part of the side wall of the sewage discharge channel 23 near the bottom wall of the sewage discharge channel 23. The connection point between the lower end of the drying duct 21 and the lower part of the side wall of the sewage discharge channel 23 can be understood as being located at the lower end of the drying duct 21, such as the bottom wall of the drying duct 21 or the part of the side wall of the drying duct 21 near the bottom wall, or it can be understood as being located at the lower part of the side wall of the sewage discharge channel 23.

[0076] The gap between the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232 and the bottom wall of the sewage discharge channel 23 refers to the fact that the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232 is not completely fitted with the bottom wall of the sewage discharge channel 23, or not fitted at all, so that there is a certain space between them for sewage to flow.

[0077] When the sewage tank 24 is vented and depressurized, the gap between the bottom of the solid-liquid separation tank 231 and / or the filter screen 232 and the bottom wall of the sewage discharge channel 23 can reduce the suction force on the dirt, prevent the sewage tank 24 from sucking in dirt and mixing with the sewage, thereby reducing the possibility of pipe blockage after the sewage is discharged into the sewer.

[0078] The bottom wall of the drying duct 21 and the bottom wall of the drain duct 23 have a guide surface 21a, which guides the hot air in the drying duct 21 from the bottom wall of the solid-liquid separation chamber 231 and / or the filter screen 232 through the solid-liquid separation chamber 231 and / or the filter screen 232. The guide surface 21a can be an inclined surface or an arc surface with a certain curvature.

[0079] If there is no gap between the solid-liquid separation chamber 231 and / or the filter screen 232 and the bottom wall of the sewage discharge channel 23, and no guide surface 21a is provided between the bottom wall of the drying air duct 21 and the bottom wall of the sewage discharge channel 23, then when hot air flows into the sewage discharge channel 23 from the bottom wall of the drying air duct 21, the hot air cannot come into contact with the solid dirt near the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232, thus causing the problem of incomplete drying of the solid dirt.

[0080] In this embodiment, by setting a gap between the solid-liquid separation chamber 231 and / or the filter screen 232 and the bottom wall of the sewage discharge channel 23, and setting a guide surface 21a between the bottom wall of the drying air duct 21 and the bottom wall of the sewage discharge channel 23, when the hot air in the drying air duct 21 flows through the guide surface 21a, the hot air will flow to the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232 under the guidance of the guide surface 21a. The hot air will then flow from bottom to top from the bottom of the solid-liquid separation chamber 231 and / or the filter screen 232, drying all solid dirt in the solid-liquid separation chamber 231 and / or the filter screen 232, without missing solid dirt and causing incomplete drying.

[0081] In addition, by setting the airflow guide surface 21a, on the one hand, the components below the cleaning base station 20 can be avoided, making the structure of the entire cleaning base station 20 more compact. On the other hand, the hot air in the drying air duct 21 can be guided to flow through the bottom wall of the solid-liquid separation chamber 231 and / or filter screen 232, so that all the dirt in the solid-liquid separation chamber 231 and / or filter screen 232 can be dried from bottom to top. This can not only prevent the damp dirt from breeding microorganisms due to not cleaning in time, but also provide convenience for the subsequent removal of dirt.

[0082] In some examples, the drain channel 23 or the solid-liquid separation chamber 231 and / or filter screen 232 may be equipped with aromatherapy components, which can remove odors from the hot air and add fragrance, so as to avoid the hot air odor after drying the dirt being too strong and affecting the user's comfort.

[0083] Reference Figure 1 and Figure 7 In some embodiments, when the cleaning device 10 is parked at the parking position 20a and the drain port 11a is open, the drain port 11a and the sludge receiving port 20b are in corresponding positions and connected. The air drive unit 25 causes the hot air generated in the drying air duct 21 to pass through the drain channel 23 and the sludge receiving port 20b, and then enter the sewage tank 11 from the drain port 11a.

[0084] If the first air drive unit 251 installed in the cleaning equipment 10 is started, the first air drive unit 251 can drive air into the drying air duct 21. During this process, the heating element 211 can heat the air in the drying air duct 21, thereby forming hot air in the drying air duct 21. The hot air enters the sewage discharge channel 23 under the guidance of the guide surface 21a, and then passes through the sewage receiving port 20b and the sewage discharge port 11a in sequence, and finally enters the sewage tank 11 to dry the sewage tank 11.

[0085] If the second air drive unit 252 installed on the cleaning base station 20 is activated, the second air drive unit 252 can drive air into the drying air duct 21. During this process, this part of the air will pass through the heating element 211. After being heated by the heating element 211, it will form hot air. Under the guidance of the guide surface 21a, the hot air enters the sewage discharge channel 23 from the drying air duct 21, and then passes through the sewage receiving port 20b and the sewage discharge port 11a in sequence, and finally enters the sewage tank 11 to dry the sewage tank 11.

[0086] If the first air drive unit 251 installed on the cleaning equipment 10 and the second air drive unit 252 installed on the cleaning base station 20 are started simultaneously, the second air drive unit 252 can drive air into the drying air duct 21. During this process, this part of the air will pass through the heating element 211 and become hot air after being heated by the heating element 211. Under the guidance of the guide surface 21a, the hot air enters the sewage discharge channel 23 from the drying air duct 21. The first air drive unit 251 can provide assistance to the hot air, driving the hot air to pass through the sewage receiving port 20b and the sewage discharge port 11a in sequence, and finally enter the sewage tank 11 to dry the sewage tank 11.

[0087] Therefore, in the above technical solution, when the cleaning equipment 10 is parked at the parking position 20a and the drain port 11a is open, by corresponding and connecting the drain port 11a and the sludge receiving port 20b, the air drive component 25 can drive external air into the drying air duct 21. This part of the air is heated by the heating component 211 to form hot air, and continues to flow in the drying air duct 21. When the hot air flows to the guide surface 21a, it enters the drain channel 23 under the guidance of the guide surface 21a. The hot air flows from bottom to top through the solid-liquid separation chamber 231 and / or filter screen 232, sludge receiving port 20b, and drain port 11a, and finally flows into the sewage tank 11, so that the water in the sewage tank 11 evaporates quickly, thereby improving the drying speed of the sewage tank 11.

[0088] For example, the above drying process may activate only the first air drive unit 251, or only the second air drive unit 252, or both the first air drive unit 251 and the second air drive unit 252 may be activated simultaneously.

[0089] Furthermore, as hot air flows into the wastewater tank 11, it also sequentially dries the drying duct 21, the solid-liquid separation chamber 231 and / or the filter 232, the sewage discharge channel 23, the sewage receiving port 20b, and the sewage discharge port 11a. In other words, the cleaning base station 20 can not only dry the wastewater tank 11 of the cleaning equipment 10, but also dry the solid-liquid separation chamber 231 and / or the filter 232, as well as the components along the hot air flow path, during the drying process of the wastewater tank 11.

[0090] Reference Figure 1 , Figure 7 and Figure 8 In some specific embodiments, the second air drive component 252 is disposed in the drying air duct 21. The second air drive component 252 and the heating component 211 are disposed at a height higher than the first water level of the sewage discharge channel 23 and the drying air duct 21. The first water level is the water level discharged into the sewage discharge channel 23 and the drying air duct 21 when the sewage tank 11 is full.

[0091] Specifically, the drying air duct 21 and the sewage discharge channel 23 are connected. When the sewage in the sewage tank 11 is discharged into the sewage discharge channel 23, some sewage will enter the drying air duct 21, and the sewage water level in the drying air duct 21 is the same as the sewage water level in the sewage discharge channel 23.

[0092] Therefore, the second air drive component 252 and the heating component 211 are installed at a height higher than the water level in the sewage discharge channel 23 and the drying air duct 21, that is, the second air drive component 252 and the heating component 211 are installed at a height higher than the first water level. This can prevent the second air drive component 252 and the heating component 211 from coming into contact with sewage, reduce the possibility of failure of the second air drive component 252 and the heating component 211, and improve the safety and reliability of the cleaning system 100.

[0093] Refer again Figure 1 , Figure 7 and Figure 8 In some embodiments, the second air drive 252 and the heating element 211 are installed at a height higher than the sewage inlet 20b.

[0094] In real life, users may encounter situations where the cleaning equipment 10 is used multiple times in a short period of time or for a long period of time. In this case, the sewage tank 11 will discharge sewage into the cleaning base station 20 multiple times. Therefore, the water level in the sewage discharge channel 23 and the drying air duct 21 may be higher than the first water level. By setting the height of the second air drive component 252 and the heating component 211 to be higher than the setting height of the sewage inlet 20b, it is possible to effectively prevent the second air drive component 252 and the heating component 211 from coming into contact with sewage in this situation, thereby reducing the possibility of failure of the second air drive component 252 and the heating component 211. This improves the safety and reliability of the cleaning system 100.

[0095] In some embodiments, the cleaning base station 20 further includes an in-situ detection element (not shown in the figure), which is used to detect the in-situ status of the cleaning device 10 at the docking position 20a. When the cleaning device 10 leaves the docking position 20a, the cleaning base station 20 controls the second air drive element 252 and the heating element 211 to stop working.

[0096] For example, the in-situ detection device can monitor the communication between the cleaning base station 20 and the cleaning equipment 10 and detect the number of data exchanges between the two. If the communication between the monitoring cleaning base station 20 and the cleaning equipment 10 is not received for several consecutive times, it is determined that the cleaning equipment 10 has left the cleaning base station 20.

[0097] If the in-situ detection device detects that the cleaning equipment 10 has left the parking position 20a, the cleaning base station 20 will control the second air drive 252 and the heating element 211 to stop working. This setting can avoid energy waste caused by the continuous operation of the second air drive 252 and the heating element 211, and reduce the possibility of the second air drive 252 and the heating element 211 malfunctioning due to long-term operation.

[0098] For example, the solid-liquid separation chamber 231 in the sewage discharge channel 23 is equipped with a positioning device (not shown in the figure), and the cleaning base station 20 is equipped with a Hall sensor (not shown in the figure). The positioning device and the Hall sensor work together to detect whether the sewage discharge channel 23 is in place, or whether the solid-liquid separation chamber 231 is in place, effectively avoiding the situation where the solid-liquid separation chamber 231 is not installed or is not installed properly, and preventing the sewage outlet 23a from becoming blocked when discharging sewage.

[0099] The positioning device can be a component such as a magnet.

[0100] Reference Figure 9 and Figure 11 In some examples, the cleaning base station 20 also includes a first humidity detection element 26, which is used to detect the humidity in the drying air duct 21 and / or the sewage discharge channel 23. If the humidity in the drying air duct 21 and / or the sewage discharge channel 23 is lower than a first preset value, the air drive element 25 and the heating element 211 are controlled to stop working.

[0101] The first preset value refers to the maximum humidity value of the drying air duct 21 and / or the sewage discharge channel 23 when it is in the drying state. If the humidity detected by the first humidity detection element 26 is lower than the first preset value, it means that the humidity in the drying air duct 21 and / or the sewage discharge channel 23 is low, and it can be determined that the drying air duct 21 and / or the sewage discharge channel 23 is in the drying state.

[0102] In the above technical solution, by setting a first humidity detection element 26, the humidity of a small portion of hot air flowing through the sewage discharge channel 23 can be detected, and the humidity in the drying air duct 21 and / or sewage discharge channel 23 can be obtained. This makes it convenient for the cleaning base station 20 to control the air drive element 25 and the heating element 211 to stop working in a timely manner after the drying air duct 21 and / or sewage discharge channel 23 is completed. This not only saves energy, but also improves the service life of the air drive element 25 and the heating element 211.

[0103] For example, a cavity 29 is provided at the top of the sewage discharge channel 23. The cavity 29 has an air inlet 233 and an air outlet 20c. A first humidity detection element 26 is disposed above the air inlet 233. Most of the hot air from the drying air duct 21 enters the sewage tank 11 sequentially through the sewage receiving port 20b and the sewage discharge port 11a, while a small portion of the hot air flows into the cavity 29 through the air inlet 233. The first humidity detection element 26 can detect the humidity of this portion of hot air. The detected hot air can continue to flow towards the top of the cavity 29 and finally flow out of the cavity 29 through the air outlet 20c.

[0104] If the humidity of the hot air is lower than the first preset value, it means that the humidity in the drying duct 21 and / or the sewage discharge channel 23 is lower than the first preset value. Therefore, it can be determined that the hot air has completed the drying of the drying duct 21 and / or the sewage discharge channel 23. At this time, the cleaning base station 20 can control the air drive component 25 and the heating component 211 to stop working.

[0105] If the humidity of the hot air is higher than the first preset value, that is, there is still moisture in the drying air duct 21 and / or the sewage discharge duct 23, the air drive unit 25 and the heating unit 211 continue to work until the humidity detected by the first humidity detection unit 26 is lower than the first preset value.

[0106] Reference Figure 2 In some examples, the cleaning device 10 also includes a second humidity detection element 27, which is used to detect the humidity in the wastewater tank 11. If the humidity in the wastewater tank 11 is lower than a second preset value, the air drive element 25 and the heating element 211 are controlled to stop working.

[0107] The second preset value refers to the maximum humidity value of the sewage tank 11 when it is in a drying state. If the humidity detected by the second humidity detection element 27 is lower than the second preset value, it means that the humidity inside the sewage tank 11 is low, and it can be determined that the sewage tank 11 is in a drying state.

[0108] Specifically, the upper part of the sewage tank 11 is provided with a first air drive component 251 and a second humidity detection component 27. After hot air enters the sewage tank 11, the first air drive component 251 can drive the hot air to flow from bottom to top, accelerate the evaporation of moisture on the inner wall of the sewage tank 11, and finally flow out of the sewage tank 11 through the first air drive component 251. The second humidity detection component 27 can detect the humidity of the hot air flowing out of the sewage tank 11.

[0109] If the humidity of the hot air here is lower than the second preset value, that is, the humidity inside the sewage tank 11 is lower than the second preset value, it is determined that the sewage tank 11 has been dried. At this time, the cleaning base station 20 can control the air drive component 25 and the heating component 211 to stop working.

[0110] If the humidity of the hot air here is higher than the second preset value, that is, there is still moisture in the sewage tank 11, the air drive 25 and the heating element 211 continue to work until the humidity detected by the second humidity detection element 27 is lower than the second preset value.

[0111] In the above technical solution, by setting a second humidity detection element 27 on the top of the sewage tank 11, the humidity of the hot air flowing out of the sewage tank 11 can be detected, and the humidity inside the sewage tank 11 can be obtained. This makes it convenient for the cleaning base station 20 to control the air drive element 25 and the heating element 211 to stop working in a timely manner after the sewage tank 11 is dried. This not only saves energy, but also improves the service life of the air drive element 25 and the heating element 211.

[0112] The cleaning system 100 according to other embodiments of the present invention is described below.

[0113] Reference Figure 2 According to an embodiment of the present invention, the cleaning system 100 includes a cleaning device 10 and a cleaning base station 20. The cleaning device 10 includes a sewage tank 11, which has an openable and closable drain outlet 11a. By opening the drain outlet 11a, sewage in the sewage tank 11 can be discharged. By closing the drain outlet 11a, the sewage tank 11 can be sealed to prevent sewage from flowing out and foreign objects from entering the sewage tank 11.

[0114] The cleaning system 100 also includes a first air drive 251, which is disposed on the cleaning device 10. When the cleaning device 10 is in a self-drying state, the first air drive 251 is adapted to drive external air from the drain outlet 11a into the sewage tank 11.

[0115] Specifically, the top of the sewage tank 11 is provided with an air outlet 11b, which allows gas to flow out of the sewage tank 11. When the cleaning equipment 10 is performing self-drying, the drain port 11a is opened. At this time, the first air drive unit 251 can drive external air to enter the sewage tank 11 from the drain port 11a and flow out from the air outlet 11b at the top of the sewage tank 11. The flowing air accelerates the evaporation of moisture inside the sewage tank 11, thereby completing the self-drying process of the sewage tank 11.

[0116] According to the cleaning system 100 of this utility model embodiment, by setting a first air drive component 251 on the cleaning device 10, air can be driven to enter the sewage tank 11 from the drain port 11a and then flow out of the sewage tank 11 from the top of the sewage tank 11. This can accelerate the evaporation of moisture inside the sewage tank 11 and realize the drying process of the sewage tank 11. This setting avoids the growth of microorganisms in the sewage tank 11 due to excessive humidity and prevents the generation of odor from the source.

[0117] Reference Figure 2 In some embodiments, the cleaning device 10 further includes a third humidity detection element 28, which is used to detect the humidity in the wastewater tank 11. If the humidity in the wastewater tank 11 is lower than a third preset value, the first air drive element 251 is controlled to stop working.

[0118] The third preset value refers to the maximum humidity value of the sewage tank 11 under the self-drying state. If the humidity detected by the third humidity detection element 28 is lower than the third preset value, it means that the humidity inside the sewage tank 11 is low, and the sewage tank 11 can be considered to be under the self-drying state.

[0119] The third humidity detection element 28 can detect the humidity inside the sewage tank 11. If the humidity inside the sewage tank 11 is lower than the third preset value, that is, the sewage tank 11 has been dried, the cleaning equipment 10 can control the first air drive element 251 to stop working. If the humidity inside the sewage tank 11 is higher than the third preset value, that is, there is still moisture inside the sewage tank 11, the first air drive element 251 continues to work until the third humidity detection element 28 detects that the humidity inside the sewage tank 11 is lower than the third preset value.

[0120] Therefore, by setting the third humidity detection element 28, the humidity value in the sewage tank 11 can be detected. After the humidity in the sewage tank 11 meets the requirements, the first air drive element 251 can be stopped by the cleaning base station 20. This not only saves energy, but also avoids the first air drive element 251 from malfunctioning due to long-term operation, which improves the reliability of the cleaning system 100.
