Detailed Implementation

[0039] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0040] The following is for reference. Figures 1-15A base station 100 according to an embodiment of the present invention is described. The base station 100 includes a sewage discharge module 110 and a drainage assembly 120. The sewage discharge module 110 has a sewage discharge channel 101, which has an open state and a closed state. In the open state, the sewage discharge channel 101 is adapted to discharge dirty liquid. In the closed state, the sewage discharge channel 101 is closed. The drainage assembly 120 includes a drive member 121 and a switch member 122. The switch member 122 is located inside the sewage discharge channel 101, and the drive member 121 is disposed outside the sewage discharge channel 101. The drive member 121 is adapted to drive the switch member 122 to move between a first position and a second position. When the switch member 122 is in the first position, the sewage discharge channel 101 is in the open state; when the switch member 122 is in the second position, the sewage discharge channel 101 is in the closed state.

[0041] Specifically, such as Figure 1 As shown, base station 100 can generally be used for cleaning equipment 200. Base station 100 can clean the cleaning equipment, for example, by adding water or charging the cleaning equipment 200. The dirty liquid generated after cleaning by the cleaning equipment 200 can be discharged into base station 100. Base station 100 can discharge the dirty liquid into a sewer or sewage discharge point. The dirty liquid can be sewage generated after cleaning by the cleaning equipment 200 or a mixture of sewage and cleaning agent. Further, base station 100 can have a sewage discharge module 110 for discharging dirty liquid. The sewage discharge module 110 can have a sewage discharge channel 101 through which the dirty liquid inside base station 100 can be discharged. The sewage discharge channel 101 can have an open state and a closed state. When the sewage discharge channel 101 is in the open state, the dirty liquid can be discharged to the outside of base station 100. When the sewage discharge channel 101 is in the closed state, the interior of base station 100 is sealed, and the dirty liquid no longer flows.

[0042] like Figure 5 and Figure 6 As shown, the drainage assembly 120 can be used to control the opening or closing of the sewage channel 101, thereby controlling whether dirty liquid is discharged from the base station 100. Further, the drainage assembly 120 may include a drive member 121 and a switch member 122. The drive member 121 may be disposed outside the sewage channel 101, and the switch member 122 may be disposed inside the sewage channel 101. The drive member 121 may be connected to the switch member 122, and the drive member 121 can drive the switch member 122 to reciprocate, so that the switch member 122 switches between a first position and a second position.

[0043] In a specific embodiment, such as Figure 5 and Figure 6As shown, when the switch 122 is in the first position, the drainage channel 101 is open; when the switch 122 is in the second position, the drainage channel 101 is closed. The drive unit 121 can control the stability and precision of the rotation of the switch 122. In other words, the switch 122 can open or close the drainage channel 101, thereby allowing the dirty liquid inside the base station 100 to be directly discharged without manual drainage.

[0044] In short, the base station 100 of the present invention is provided with a sewage discharge module 110 for discharging dirty liquid. A sewage discharge channel 101 is formed inside the sewage discharge module 110. A switch 122 can be set inside the sewage discharge channel 101 and the switch 122 is controlled to open or close by a drive 121, thereby controlling whether the sewage discharge channel 101 discharges the dirty liquid in the base station 100. The above sewage discharge method can realize the intelligent sewage discharge of the base station 100, eliminating the need for users to manually dump sewage, improving the sewage discharge efficiency of the base station 100, and providing convenience for users.

[0045] like Figure 2 As shown, in some embodiments of the present invention, the base station 100 may have a wastewater tank 130, which can be used to collect dirty liquid. The dirty liquid in the wastewater tank 130 can be discharged through the drain channel 101. The drainage component 120 can be used to control the opening and closing of the drain channel 101, thereby controlling whether the dirty liquid in the wastewater tank 130 is discharged. In actual use, the wastewater tank 130 can be used to collect wastewater from the cleaning equipment 200 or wastewater generated during the cleaning of the base station 100. The wastewater tank 130 can be connected to the drain channel 101. When the wastewater content in the wastewater tank 130 reaches a certain level, the base station 100 can open the drain channel 101 through the switch component 122 to discharge the wastewater all at once, increasing the wastewater discharge efficiency of the base station 100. After the wastewater is discharged, the switch component 122 can close the drain channel 101, thereby effectively preventing dirt or odors from entering the wastewater tank 130 from the drain channel 101, thus achieving cleanliness of the wastewater tank 130 and improving the user experience. More specifically, the sewage discharge channel 101 can be connected to the sewer to discharge sewage directly into the sewer.

[0046] like Figure 3 and Figure 4As shown, in some embodiments of the present invention, the driving member 121 may include a motor 1211, a first transmission member 1213, a second transmission member 1214 and a fixed bracket 1215. The motor 1211 can serve as a power source for the driving member 121, providing power to the driving member 121, thereby enabling the driving member 121 to drive the switching member 122 to reciprocate. Furthermore, the motor 1211 may have a first output shaft 1212, and the first transmission member 1213 may be connected to the first output shaft 1212. It is understood that the first transmission member 1213 may be sleeved on the outer wall of the first output shaft 1212 and fixedly connected to the first output shaft 1212 to ensure that the first transmission member 1213 can rotate synchronously with the first output shaft 1212 when the first output shaft 1212 rotates. One end of the second transmission member 1214 may be connected to the first output shaft 1212, and the other end of the second transmission member 1214 may be indirectly fixed to the switch member 122. Therefore, when the motor 1211 is working, the first output shaft 1212 can drive the first transmission member 1213 to rotate, the first transmission member 1213 can drive the second transmission member 1214 to rotate, and the second transmission member 1214 can drive the switch member 122 to switch between a first position and a second position to realize the opening or closing of the sewage discharge channel 101. A fixed bracket 1215 can also be provided outside the sewage discharge channel 101. The fixed bracket 1215 can be fixedly connected to the sewage discharge module 110, and the fixed bracket 1215 can be used to fix the motor 1211 and / or the first transmission component 1213 to prevent the motor 1211 and / or the first transmission component 1213 from detaching or falling off, thereby improving the reliability of the drive component 121.

[0047] In some embodiments of the present invention, the first transmission member 1213 can be constructed as a worm gear, and the second transmission member 1214 can be constructed as a worm wheel, with the worm wheel positioned above the worm gear. The first transmission member 1213 and the second transmission member 1214 can mesh and transmit power. The use of a worm wheel and worm gear structure can increase the output torque of the drive member 121 and improve its working efficiency. Furthermore, the worm wheel and worm gear have a self-locking function. When the sewage tank 130 contains a large amount of sewage, the switch member 122 is in the second position, and the sewage discharge channel 101 is closed, the base station 100 can utilize the self-locking function of the worm wheel and worm gear to further prevent the switch member 122 from being opened by the sewage.

[0048] like Figure 8As shown, in some embodiments of the present invention, the drainage assembly 120 may further include a switch shaft 123. The switch shaft 123 may have a first limiting portion 1231 and a second limiting portion 1232. The first limiting portion 1231 may be located outside the sewage channel 101. A first mounting hole may be formed on the worm gear. The first limiting portion 1231 may penetrate the first mounting hole, and the outer wall of the first limiting portion 1231 may cooperate with the inner wall of the first mounting hole to realize that the switch shaft 123 can rotate synchronously with the worm gear. Specifically, the cross-section of the first limiting portion 1231 in the axial direction of the switch shaft 123 may be non-circular, thereby ensuring that the first limiting portion 1231 and the first mounting hole are in harmony. The holes can rotate synchronously to prevent slippage between the first limiting part 1231 and the first mounting hole. The second limiting part 1232 can be located inside the sewage channel 101, and the switch 122 can be sleeved on the outside of the second limiting part 1232. The axial cross-section of the switch shaft 123 of the second limiting part 1232 can be non-circular to ensure that the switch 122 can rotate with the second limiting part 1232. In a specific embodiment, when the worm gear rotates, the switch shaft 123 connected to the worm gear can rotate coaxially with the worm gear. The switch shaft 123 can drive the switch 122 to rotate, thereby enabling the switch 122 to open or close the sewage channel 101.

[0049] like Figure 8 As shown, in some embodiments of the present invention, the switch shaft 123 may further include a third limiting part 1233, which may be coaxial with and fixedly connected to the first limiting part 1231. The drainage assembly 120 may further include a trigger rod 124, on which a second mounting hole may be formed. The second mounting hole may cooperate with the third limiting part 1233, and the outer wall of the third limiting part 1233 may cooperate with the inner wall of the second mounting hole, so that the trigger rod 124 can rotate synchronously with the switch shaft 123. Specifically, the cross-section of the third limiting part 1233 in the axial direction of the switch shaft 123 may be non-circular, thereby ensuring that the trigger rod 124 and the switch shaft 123 can rotate synchronously and preventing slippage between the trigger rod 124 and the switch shaft 123.

[0050] like Figure 7As shown, in some embodiments of the present invention, the drainage assembly 120 may further include a first trigger 125 and a second trigger 126. The trigger rod 124 can rotate with the second transmission member 1214 to contact the first trigger 125 and the second trigger 126. Specifically, the first trigger 125 can be disposed on and fixedly connected to the fixed bracket 1215. The first trigger 125 can contact the trigger rod 124 and transmit a signal to the control component when the switch member 122 is rotated to the first position. The control component can control the first output shaft 1212 of the motor 1211 to stop rotating. Similarly, the second trigger 126 can be disposed on and fixedly connected to the fixed bracket 1215. The second trigger 126 can contact the trigger rod 124 and transmit a signal to the control component when the switch member 122 is rotated to the second position. The control component can control the first output shaft 1212 of the motor 1211 to stop rotating. By adopting this structure of trigger rod 124, first trigger 125 and second trigger 126, the drive member 121 can be controlled more effectively.

[0051] In some embodiments of the present invention, the base station 100 may further include a control component, which is electrically connected to the drive component 121. The drive component can control the motor 1211 to stop rotating when the trigger rod 124 triggers the first trigger 125 or the trigger rod 124 triggers the second trigger 126. Specifically, when the first trigger 125 contacts the trigger rod 124 and transmits a signal to the control component when the switch 122 rotates to the first position, the control component can control the first output shaft 1212 of the motor 1211 to stop rotating according to the received signal. When the second trigger 126 contacts the trigger rod 124 and transmits a signal to the control component when the switch 122 rotates to the second position, the control component can control the first output shaft 1212 of the motor 1211 to stop rotating according to the received signal. The above control method can improve the intelligence of the base station 100.

[0052] In some embodiments of the present invention, the first trigger 125 and the second trigger 126 can be configured as microswitches. Microswitches have waterproof, acid-proof and corrosion-proof properties. Compared with traditional switches, microswitches have a compact internal structure, the force between contacts can be transmitted quickly, the sensitivity is higher, and the service life of microswitches is longer, reducing the failure rate of the drive component 121. However, it is not limited to this. The trigger rod 124 and the first trigger 125 and the second trigger 126 can adopt a non-contact triggering structure. For example, the trigger rod 124, the first trigger 125 and the second trigger 126 can be configured as Hall elements and magnets.

[0053] In some embodiments of the present invention, the fixing bracket 1215 and the sewage module 110 can be constructed as an integral molded part. By integrally molding the fixing bracket 1215 and the sewage module 110, the number of production lines for parts can be greatly reduced, and the fixing processes such as welding or screwing can be reduced, thereby improving installation efficiency and processing efficiency and reducing the number of molds.

[0054] like Figure 11 and Figure 12 As shown, in some embodiments of the present invention, the drive unit 121 may include a servo motor 1216. One end of the servo motor 1216 may be provided with a second output shaft. The second output shaft may be directly connected to the switch unit 122, so that the switch unit 122 can rotate between a first position and a second position to open and close the sewage discharge channel 101. Using a servo motor 1216 can simplify the structure of the drive unit 121 and improve the stability of operation.

[0055] In some embodiments of the present invention, the connection point between the second output shaft and the switch 122 can be located above the drain channel 101. The upper end of the switch 122 can be hinged to the upper part of the drain channel 101, ensuring that the switch 122 can rotate relative to the top wall of the drain channel 101, and the lower end of the switch 122 can cooperate with the bottom wall of the drain channel 101 to close the drain channel 101. Specifically, the switch 122 flips upward, allowing dirty liquid to flow downward along the bottom wall of the drain channel 101. This prevents the dirty liquid from easily washing over the switch 122, thus protecting the switch 122, and the switch 122 does not obstruct the flow of dirty liquid. When the switch 122 is closed, the switch 122 flips downward from the open state, gradually closing the drain outlet 1311 and sealing the top wall and bottom wall of the drain channel 101.

[0056] In some embodiments of the present invention, the included angle between the first position and the second position can be α, and the included angle α can satisfy: 30°<α<120°. By setting the included angle between the first position and the second position within the above range, the distance that the switch 122 moves between the first position and the second position can be shortened, the control accuracy can be improved, and the switch 122 can effectively open or close the sewage channel 101. When the switch 122 is in the first position, the sewage channel 101 is in the open state, and when the switch 122 is in the second position, the sewage channel 101 is in the closed state. Furthermore, the space occupied by the switch 122 when it moves is small, which is beneficial for space arrangement.

[0057] like Figure 3 and Figure 4As shown, in some embodiments of the present invention, the base station 100 may further include a sewage tank 130. The sewage tank 130 may include a tank body 131 and a soft rubber seal 132. A sewage outlet 1311 may be provided at the bottom of the tank body 131. The sewage outlet 1311 may be connected to the sewage channel 101. Specifically, the sewage discharge module 110 may be provided below the sewage tank 130 and may be fixedly connected to the sewage tank 130. The dirty liquid in the sewage tank 130 may flow into the sewage channel 101 through the sewage outlet 1311. The sewage outlet 1311 may be provided at the bottom of the tank body 131 so that the dirty liquid can flow to the bottom of the sewage tank 130 and be discharged due to gravity. Therefore, providing the sewage outlet 1311 at the above position is beneficial for draining the dirty liquid. The sewage channel 101 is connected to the sewage outlet 1311 so that the dirty liquid in the tank body 131 can be guided into the sewage channel 101 to achieve the discharge of the dirty liquid. The soft rubber seal 132 can be set at the connection between the sewage outlet 1311 and the sewage channel 101. The soft rubber seal 132 can fit against the outer wall of the sewage outlet 1311. The soft rubber seal 132 can be made of a material with high sealing performance. The soft rubber seal 132 helps to improve the sealing effect of the connection between the sewage tank 130 and the sewage channel 101.

[0058] like Figure 5 As shown, in some embodiments of the present invention, the cross-sectional area of ​​the inner wall of the box 131 gradually decreases from top to bottom, and an inclined surface extending at an angle is defined on the inner wall of the box 131. In this way, the inclined surface at the bottom of the box 131 can guide the sewage at the bottom of the box 131 to flow downward to the drain outlet 1311 based on its own gravity, thereby avoiding sewage residue at the bottom of the box 131 and improving the sewage discharge effect.

[0059] like Figure 10 As shown, in some embodiments of the present invention, a spray assembly 133 may be provided inside the sewage tank 130. The sewage tank 130 may also include a tank cover 1312, which can be opened to close the top of the tank body 131. The spray assembly 133 may be located on the upper part of the sewage tank 130 or near the tank cover 1312. In this way, the water sprayed by the spray assembly 133 can be sprayed downward from the top wall of the sewage tank 130, which helps to increase the contact area between the spray water and the inner wall of the sewage tank 130. In addition, the spray assembly 133 sprays water above the sewage tank 130. After the water comes into contact with the inner wall of the sewage tank 130, it flows downward based on its own gravity, so that the water can continuously clean during the spraying process, thereby further improving the cleaning effect.

[0060] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, the sewage discharge module 110 may include a first segment 111, a second segment 112, and a third segment 113. The first segment 111, the second segment 112, and the third segment 113 may be connected in sequence. In the direction perpendicular to the extension of the sewage discharge module 110, the cross-sectional area of ​​the second segment 112 is larger than the cross-sectional areas of the first segment 111 and the third segment 113. The switch element 122 may be disposed in the second segment 112. Increasing the cross-sectional area of ​​the second segment 112 facilitates the installation of the switch element 122.

[0061] In some embodiments of the present invention, the first segment 111 may be tilted at an acute angle relative to the axis of the drain outlet 1311. When the switch 122 is in the closed state, the switch 122 can close the first segment 111. Specifically, the first segment 111 may be tilted downwards to guide the dirty liquid into the drain channel 101, thus solving problems such as sewage residue or sewage backflow.

[0062] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the first segment 111 can be constructed in a curved shape. The curved shape of the first segment 111 can, to a certain extent, block the upward flow of odors from the sewage discharge channel 101 or the sewer to the sewage tank 130, thereby improving the user experience. In addition, when the user cleans the sewage tank 130 or the sewage discharge module 110, the water can form a vortex or eddy in the first segment 111, which is beneficial to improving the cleaning effect.

[0063] like Figure 10 As shown, in some embodiments of the present invention, the drain outlet 1311 can be constructed as a tube extending in the vertical direction to ensure that the water is guided to flow from top to bottom to the drain channel 101. At the same time, the vertically extending tube can increase the cross-sectional area of ​​the drain outlet 1311 so that dirty liquid can be discharged through the drain outlet 1311, thereby improving the sewage discharge effect. The upper end of the drain outlet 1311 is connected to the box 131, which can shorten the flow path and reduce the space occupied by the drain outlet 1311, making the space arrangement easier.

[0064] like Figure 4 As shown, in some embodiments of the present invention, the soft rubber seal 132 can be disposed at the connection between the drain outlet 1311 and the first segment 111, and the soft rubber seal 132 can fit against the outer wall of the drain outlet 1311. In other embodiments of the present invention, the first segment 111 can be threadedly connected to the drain outlet 1311 and sealed, thereby improving the sealing effect of the connection between the drain channel 101 and the drain outlet 1311 and the structural stability after the connection, thus avoiding the risk of sewage leakage.

[0065] In some embodiments of the present invention, a stepped surface may be provided on the inner side of the bottom wall of the first segment 111. When the switch 122 closes the sewage channel 101, the lower end of the switch 122 can abut against the stepped surface, thereby effectively improving the sealing effect of the switch 122 and preventing sewage from leaking between the switch 122 and the sewage channel 101.

[0066] like Figure 9 As shown, in some embodiments of the present invention, the horizontal height of the first segment 111, the second segment 112 and the third segment 113 can be gradually reduced to ensure that the dirty liquid can flow through the first segment 111, the second segment 112 and the third segment 113 in sequence and be discharged based on the influence of gravity. Therefore, gradually reducing the horizontal height of the first segment 111, the second segment 112 and the third segment 113 can improve the discharge efficiency of the dirty liquid.

[0067] like Figure 5 and Figure 9 As shown, in some embodiments of the present invention, the second segment 112 may include a first housing 1121 and a second housing 1122. The first housing 1121 may be fixedly connected to the first segment 111 and the third segment 113, and a partial sewage discharge channel 101 may be formed inside the first housing 1121, which can be used for the flow of dirty liquid. The second housing 1122 may be disposed on the side of the first housing 1121 facing the sewage tank 130, and a receiving cavity 1123 may be formed inside the second housing 1122. The receiving cavity 1123 may be connected to the sewage discharge channel 101. The switch 122 may be located in the sewage discharge channel 101 or the receiving cavity 1123. The drive 121 may drive the switch 122 to move between the sewage discharge channel 101 and the receiving cavity 1123. When the switch 122 is located in the receiving cavity 1123, the sewage discharge channel 101 may be in an open state; when the switch 122 is located in the sewage discharge channel 101, the sewage discharge channel 101 may be in a closed state.

[0068] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, the second housing 1122 may have an opening 1124 on the side facing the cover 1125. The opening 1124 can be used for the installation of the switch 122, so that the switch 122 can be installed into the second housing 1122. The second section 112 may also include the cover 1125, which can be disposed between the second housing 1122 and the sewage tank 130, and the cover 1125 can be fixedly connected to the second housing 1122. The cover 1125 and the second housing 1122 can be detachably connected by means of screws, snaps, etc. The cover 1125 can be used to close the opening 1124, so that the switch 122 is kept inside the second housing 1122. After the switch 122 is installed into the second housing 1122, the cover 1125 can be fixedly connected to the second housing 1122 to complete the assembly of the switch 122. When the switch 122 needs maintenance, the switch 122 can be maintained simply by removing the cover 1125 and replacing the switch 122. This reduces the maintenance difficulty of the sewage discharge assembly and improves the maintenance efficiency of the sewage discharge assembly.

[0069] like Figure 5 As shown, in some embodiments of the present invention, the cross-section of the cover 1125 in the height direction can be rectangular, and the shape of the opening 1124 can be rectangular. By setting the cross-sections of the cover 1125 and the opening 1124 to rectangles, the sealing effect between the cover 1125 and the opening 1124 can be improved. At the same time, the accommodating space inside the second housing 1122 can be increased, which facilitates the installation of the switch 122 and the rotation of the switch 122.

[0070] like Figure 9 As shown, in some embodiments of the present invention, the sewage channel 101 may have a water outlet 1011, wherein the direction of the sewage outlet 1311 toward the water outlet 1011 may be a first direction, and the direction of the water outlet 1011 toward the sewage outlet 1311 may be a second direction. The switch 122 may move along the first direction to switch the sewage channel 101 from an open state to a closed state, and the switch 122 may move along the second direction to switch the sewage channel 101 from a closed state to an open state. Using the above directions to open or close the switch 122 can ensure that dirty liquid does not easily wash the switch 122, which is beneficial to protect the switch 122, and the switch 122 will not block the flow of dirty liquid. The outlet 1011 can be connected to the hose 140. The outer peripheral wall of the outlet end can be provided with threads so that the outlet 1011 can be threadedly engaged with the hose 140. One end of the hose 140 can be engaged with the outlet 1011, and the other end of the hose 140 can be inserted into the sewer to discharge the dirty liquid in the sewage tank 130 into the sewer.

[0071] In some embodiments of the present invention, the base station 100 further includes a water level monitoring device, which can be connected to the control component. The water level monitoring device can detect the first sewage volume in the tank 131 or the second sewage volume in the sewage discharge channel 101, or the water level monitoring device can simultaneously detect the first sewage volume in the tank 131 and the second sewage volume in the sewage discharge channel 101. The control component can control the start or stop of the drive unit 121 according to the first sewage volume and the second sewage volume. Furthermore, the control component can convert the water level signal of the water level monitoring device into an electrical signal for the drive unit 121 to control the operation of the drive unit 121 according to the water level signal.

[0072] In a specific embodiment, a water level monitoring device can be installed above the tank 131 to detect the highest water level in the sewage tank 130 and to drain water when the sewage tank 130 is about to be full or is already full. The sewage discharge channel 101 can automatically open or close when the water level in the sewage tank 130 reaches a predetermined level. The water level monitoring device can be used to detect the preset highest water level or the preset lowest water level, for example, by using an infrared water level detector or by also installing a water level detector at the bottom of the sewage tank 130. Thus, when the water level in the sewage tank 130 reaches the preset highest water level, the water level monitoring device transmits a signal to the switch 122 to control the switch 122 to open the sewage discharge channel 101; when the water level in the sewage tank 130 reaches the preset lowest water level, the water level monitoring device transmits a signal to the switch 122 to control the switch 122 to close the sewage discharge channel 101. Alternatively, the user can manually open or close the sewage discharge channel 101 according to the actual situation. Alternatively, the sewage discharge channel 101 may be automatically opened after a certain step of the self-cleaning process is completed, for example, after the cleaning equipment 200 docked at the base station 100 has completed the sewage extraction.

[0073] like Figure 1As shown, in some embodiments of the present invention, the base station 100 may further include a clean water tank 105, which is connected to a wastewater tank 130. Water in the clean water tank 105 can enter the wastewater tank 130 to clean it, or water in the clean water tank 105 can clean the sewage discharge channel 101. Specifically, the clean water in the clean water tank 105 can be used to supply cleaning equipment 200 for cleaning, and the clean water in the clean water tank 105 can also be introduced into the wastewater tank 130 to clean it. This structure allows for full utilization of the water in the clean water tank 105. In this way, clean water can flow from the bottom of the sewage tank 130 body 131 into the sewage channel 101 through the sewage outlet 1311, and carry away the sewage remaining at the bottom of the tank 131 and the sewage outlet 1311, thereby achieving the effect of cleaning the sewage tank 130. At the same time, when the clean water flows into the sewage channel 101, it can also clean the sewage channel 101 and the sewer, which is conducive to improving the sewage environment.

[0074] Furthermore, in some embodiments of the present invention, the base station 100 also includes a pump (not shown in the figure), which can be connected to a clean water tank 105 and a wastewater tank 130. The pump can draw water from the clean water tank 105 and send it to the wastewater tank 130, thereby directing the clean water in the clean water tank 105 to the wastewater tank 130 for flushing. In addition, the water transported by the pump can also be pressurized, so that the clean water delivered to the wastewater tank 130 has a certain pressure, which is beneficial to improving the flushing effect.

[0075] like Figure 1 As shown, the cleaning system 300 of the present invention will be briefly described below.

[0076] The cleaning system 300 according to the present invention includes a base station 100 and a cleaning device 200 as described in the above embodiments. The cleaning device 200 can be docked at the base station 100. The base station 100 can place the cleaning device 200 and clean it to remove sewage from the cleaning device 200, rinse the cleaning device 200, and store a sufficient amount of clean water for subsequent use of the cleaning device 200.

[0077] Specifically, the cleaning device 200 can be connected to the base station 100. The base station 100 can clean the cleaning device 200, such as by adding water or charging it. Wastewater generated after cleaning by the cleaning device 200 can be discharged into the wastewater tank 130 of the base station 100. Alternatively, wastewater generated by the base station 100 during the cleaning of the cleaning device 200 can be discharged into the wastewater tank 130. When the wastewater in the wastewater tank 130 reaches a certain level, the switch 122 can open the drain channel 101 to discharge the wastewater all at once, improving cleaning efficiency, eliminating the need for manual operation, and preventing user contact with wastewater, thus enhancing the intelligence of the base station 100. The connection or closure between the wastewater tank 130 and the drain channel 101 can be controlled. This allows the wastewater tank 130 and the drain channel 101 to be connected only during wastewater discharge, preventing dirt and odors from the drain channel 101 from entering the wastewater tank 130 and improving the cleanliness of the wastewater tank 130.

[0078] In some embodiments of the present invention, the base station 100 may include a first sewage inlet, and the cleaning device 200 may include a second sewage inlet. The first sewage inlet may be connected to the second sewage inlet to collect the sewage from the cleaning device 200 into the sewage tank 130 of the base station 100, so that the sewage can be discharged from the sewage tank 130 into the sewage discharge channel 101.

[0079] Furthermore, such as Figure 1 As shown, the cleaning equipment 200 may include a water storage tank 210. The water storage tank 210 can be used to collect dirty liquid generated during the cleaning process or to store clean water for cleaning. When the cleaning equipment 200 is docked at the base station 100, the water storage tank 210 and the sewage tank 130 are connected through the docking of the first and second sewage inlets, so that the sewage collected by the cleaning equipment 200 can be pumped to the sewage tank 130 of the base station 100, and then the sewage can be automatically discharged from the sewage tank 130 of the base station 100. Thus, the user can treat sewage and dirt without manual operation, providing convenience for the user.

[0080] The following is a reference to the appendix. Figure 1-12 A base station 100 according to a specific embodiment of the present invention is described.

[0081] According to an embodiment of the present invention, after the cleaning equipment 200 has finished cleaning, the base station 100 can be placed on the base station 100 for water replenishment, sewage extraction, self-cleaning, and charging. Specifically, the base station 100 may include a base and a tray 103. The base may include a main unit 102, a clean water tank 105, and a wastewater tank 130. The main unit 102 may be located at the center of the base for easy connection with the cleaning equipment 200. The clean water tank 105 and the wastewater tank 130 may be respectively located on both sides of the main unit 102. This structure facilitates space arrangement. The clean water in the clean water tank 105 can be used to clean the cleaning equipment 200 or to supply water to the cleaning equipment 200. A shelf 104 may also be provided on the base. The shelf 104 may be located on one side near the base or one side near the wastewater tank 130. The shelf 104 can be used to place a cleaning brush. Users can use the cleaning brush to clean the inside of the wastewater tank 130, providing convenience for users. The tray 103 is connected to the lower part of the base, and a receiving cavity can be formed on the upper part of the tray 103. The receiving cavity can be used to place the floor brush of the cleaning equipment 200 for cleaning or drying.

[0082] Furthermore, a drive component 121 is provided below the sewage tank 130. The function of the drive component 121 is to control the switch component 122 to reciprocate and rotate at a certain angle. The switch component 122 has a first position and a second position. When the switch component 122 is in the first position, the sewage discharge channel 101 can remain unobstructed, and the sewage in the sewage tank 130 can be discharged into the sewage discharge channel 101; in the second position, the sewage discharge channel 101 is blocked.

[0083] In practical applications, when the water level in the sewage tank 130 reaches the preset value, the drive component can control the drive component 121 to switch from the closed state to the open state, so as to adjust the switch component 122 from the second position to the first position. At this time, the dirty liquid in the sewage tank 130 can be discharged into the sewage discharge channel 101, and then discharged into the sewer from the sewage discharge channel 101.

[0084] In addition, a pump can be installed between the clean water tank 105 and the wastewater tank 130 of the base station 100. During the self-cleaning process, after the cleaning equipment 200 finishes cleaning, the liquid in the clean water tank 105 needs to be pumped from the base station 100 clean water tank 105 to the base station 100 wastewater tank 130. After the water in the base station 100 wastewater tank 130 reaches a preset level, the control drive 121 opens the sewage discharge channel 101, and the water in the wastewater tank 130 is flushed into the sewage discharge channel 101 at once, completing the flushing of the wastewater tank 130 and the sewage discharge channel 101.

[0085] The following is for reference. Figures 1-15A control method for a base station for a cleaning device according to an embodiment of the present invention is described. The base station includes a sewage discharge channel having an open state and a closed state. In the open state, the sewage discharge channel is adapted to discharge dirty liquid, and in the closed state, the sewage discharge channel is closed. The control method includes: acquiring an open signal and a closed signal of the sewage discharge channel; and controlling the sewage discharge channel to switch between the open state and the closed state based on the open signal and the closed signal.

[0086] Specifically, such as Figure 13 As shown, the control methods include:

[0087] S1. Obtain the opening and closing signals of the sewage discharge channel. The opening and closing signals of the sewage discharge channel can be manually controlled. For example, a user can manually operate the base station and execute the opening or closing of the sewage discharge channel to obtain the opening and closing signals. The user can also issue the opening and closing signals of the sewage discharge channel by triggering the opening or closing button. Alternatively, the opening and closing signals of the sewage discharge channel can be determined by the base station performing certain cleaning functions, based on actual needs. However, this is not limited to these methods. The opening and closing signals of the sewage discharge channel can also be determined by a water level monitoring device. For example, the water level monitoring device can be connected to the control component and can simultaneously detect the first sewage volume in the tank and the second sewage volume in the sewage discharge channel. The control component can control the opening or closing of the sewage discharge channel based on the first sewage volume and the second sewage volume.

[0088] S2. Based on the open and close signals, control the sewage discharge channel to switch between open and closed states. Upon receiving the open and close signals, the drive unit can be controlled to switch the switch between a first position and a second position, thereby controlling the sewage discharge channel to switch between open and closed states. That is, the switch can open or close the sewage discharge channel to achieve the effect of discharging dirty liquid through it. Dirty liquid can refer to sewage in the sewage tank, water used to clean the sewage tank, or a mixture of water and cleaning agent. This control method facilitates the direct discharge of dirty liquid from the base station without the need for manual sewage discharge.

[0089] In short, the control method of the present invention first obtains the opening signal and closing signal of the sewage discharge channel, and then controls the sewage discharge channel to switch between the open state and the closed state according to the opening signal and the closing signal, so as to realize the discharge of dirty liquid in the base station through the sewage discharge channel, further improving the intelligence of the base station and providing convenience for users.

[0090] like Figure 14 As shown, in some embodiments of the present invention, the control method may further include:

[0091] S101. Obtain the current docking status of the cleaning equipment at the base station and the cleaning commands from the base station. The current docking status of the cleaning equipment at the base station refers to whether the cleaning setup has been completed and placed on the base station. The cleaning equipment can issue cleaning commands at the base station, which can include functions such as water replenishment, dirt removal, self-cleaning, and charging.

[0092] S102. Based on the equipment's docking status and cleaning instructions, control the base station to execute a self-cleaning program and send an open or closed signal to the drainage channel. When the cleaning equipment is docked at the base station, the user or the cleaning system can control the base station to execute the self-cleaning program and simultaneously send an open or closed signal to the drainage channel. The opening or closing of the drainage channel can be controlled according to the actual needs of the self-cleaning program. In other embodiments, when the base station is powered on, it can default to opening the drainage channel. At this time, the drainage channel is already in an open state, and the controller does not need to control the drainage channel anymore. Furthermore, the cleaning equipment can communicate with the base station via a terminal. The base station can have a manual self-cleaning mode and an automatic self-cleaning mode. When the base station is in manual self-cleaning mode, the self-cleaning program of the base station needs to be manually triggered by the user, for example, by pressing the self-cleaning button on the cleaning equipment handle, and then starting the self-cleaning program. The cleaning equipment and the base station communicate during the self-cleaning program via the terminal. When the base station is in automatic self-cleaning mode, the self-cleaning program does not require manual triggering by the user. Instead, after the cleaning equipment docks on the base station, the base station and the cleaning equipment communicate to identify whether self-cleaning is required. Once it is determined that self-cleaning is required, the self-cleaning program is automatically started.

[0093] like Figure 1 As shown, in some embodiments of the present invention, the base station may include a first wastewater tank, which can be used to collect dirty liquid. The first wastewater tank is connected to a drainage channel, and the dirty liquid in the first wastewater tank can be discharged through the drainage channel. The cleaning equipment may include a second wastewater tank, which may be selectively connected to the first wastewater tank. The second wastewater tank may be constructed as a water storage tank as described in the above embodiments. The second wastewater tank can be used to collect dirty liquid generated during the cleaning process of the cleaning equipment or to store clean water for cleaning. When the cleaning equipment is docked at the base station, the first wastewater tank and the second wastewater tank are connected, so that the wastewater collected by the cleaning equipment can be pumped to the first wastewater tank of the base station, thereby allowing the wastewater to be automatically discharged from the first wastewater tank of the base station. Further, controlling the base station to execute a self-cleaning program and sending an open or closed signal to the drainage channel according to the self-cleaning program includes:

[0094] S103. A closing signal is sent to the sewage discharge channel, and the sewage discharge channel is controlled to be closed for a first preset time period. After the sewage discharge channel is closed, the sewage in the second sewage tank is discharged into the first sewage tank for the same duration. First, a closing signal is sent to the sewage discharge channel, and the sewage discharge channel is controlled to be closed. The closed state can last for a first preset time period, which can be T1, and T1 can satisfy: T1 < 30s. In this state, the sewage discharge channel is closed, and the sewage in the second sewage tank is discharged into the first sewage tank, realizing the sewage pumping procedure of the cleaning equipment to pump the sewage collected by the cleaning equipment into the first sewage tank of the base station. Preferably, T1 < 10s.

[0095] In some embodiments of the present invention, the base station may further include a negative pressure device, which may be connected to a first sewage tank. The negative pressure device may pump sewage from a second sewage tank into the first sewage tank. Specifically, the negative pressure device may generate negative pressure, creating a pressure difference between the first and second sewage tanks. Due to the pressure difference, sewage in the second sewage tank may be discharged into the first sewage tank. The activation time of the negative pressure device may be a first preset duration, ensuring that the negative pressure device can completely pump out the sewage from the second sewage tank.

[0096] like Figure 10 As shown, in some embodiments of the present invention, when the sewage in the second sewage tank is discharged into the first sewage tank and the discharge time reaches a first preset duration, an opening signal can be sent to the sewage discharge channel to control the sewage discharge channel to be in an open state. At this time, the sewage discharged from the second sewage tank into the first sewage tank can be discharged to the outside of the base station through the sewage discharge channel, thereby realizing the sewage discharge of the second sewage tank. After the sewage is discharged, the base station can perform procedures such as water replenishment on the cleaning equipment.

[0097] In some embodiments of the present invention, a spray assembly can be installed inside the first sewage tank. The spray assembly can be located at the top of the sewage tank or near the tank cover. This allows the water sprayed from the spray assembly to fall downwards from the top wall of the sewage tank, increasing the contact area between the spray water and the inner wall of the sewage tank. Furthermore, since the spray assembly sprays water above the sewage tank, the water flows downwards due to gravity after contacting the inner wall, continuously rinsing the inner wall of the first sewage tank during the spraying process. The spraying duration can be set according to user needs, or it can be automatically determined by detecting the bacteria or sewage content inside the tank using a detection device. The control method may further include:

[0098] like Figure 14As shown in step S104, after the sewage discharge channel is open, the spray assembly is controlled to rinse the inner wall of the first sewage tank for a second preset time. When sewage from the second sewage tank is discharged into the first sewage tank, the sewage discharge channel can be open, allowing the spray assembly to rinse the inner wall of the first sewage tank to remove dirt or stains, ensuring cleanliness, reducing odor, and improving user satisfaction. The spray assembly can rinse the inner wall of the first sewage tank for the second preset time, T2, which must satisfy: T2 < 60s. The second preset time T2 is preferably around 15s. Of course, the second preset time can be set according to actual needs. For example, when the sewage content in the first sewage tank is too high in step S103, the spray assembly can increase the rinsing time of the sewage tank.

[0099] like Figure 14 As shown, in some embodiments of the present invention, after step S104, when the spray assembly rinses the inner wall of the first sewage tank and runs for a second preset time, the control method may further include:

[0100] S105. Send a closing signal to the sewage discharge channel and control the sewage discharge channel to be in the closed state. At this time, the spray assembly is not in the open state, and the sewage discharge channel is closed.

[0101] S106. Control the spray assembly to rinse the inner wall of the first sewage tank for a third preset time. After the sewage discharge channel is closed, the spray assembly rinses the inner wall of the first sewage tank. At this time, the spray assembly can spray the first sewage tank a second time. By setting two sprays, the first sewage tank can be effectively rinsed and cleaned, reducing the bacterial content and odor in the first sewage tank, greatly improving the cleanliness of the first sewage tank and meeting the user's needs. The second spray can last for a third preset time, which can be T3, and T3 can satisfy: 60s < T3 < 240s. By setting the third preset time within the above range, the cleaning effect of the second spray on the first sewage tank can be effectively improved, making the self-cleaning effect of the base station's first sewage tank better and less prone to residual garbage and odor problems.

[0102] In some embodiments of the present invention, the third preset duration can be greater than the second preset duration to ensure that the effect of the second spray is greater than that of the first spray. In the first spray, the spray assembly can spray the inner wall of the first sewage tank. After the second preset duration is reached, the sewage discharge channel is opened. At this time, the opening time of the sewage discharge channel can be between 1 second and 4 seconds. After the sewage is discharged, the sewage discharge channel is closed, and the spray assembly sprays the inner wall of the first sewage tank a second time, which more effectively cleans the inner wall of the first sewage tank. Furthermore, the second spray can improve the cleaning effect of the spray assembly.

[0103] like Figure 14 As shown, in some embodiments of the present invention, the control method further includes:

[0104] S107. After the spray assembly has rinsed the inner wall of the first sewage tank for a third preset time, an opening signal is sent to the sewage discharge channel and the sewage discharge channel is controlled to be in the open state. After the spray assembly has rinsed the inner wall of the first sewage tank for a third preset time, an opening signal can be sent to the sewage discharge channel and the sewage discharge channel can be controlled to be in the open state. At this time, the sewage generated in the first sewage tank after the second spray can be discharged to the outside of the base station, thereby completing the cleaning of the first sewage tank. The sewage in the first sewage tank can flow out along the inner wall of the first sewage tank to dry the first sewage tank. At the same time, a large amount of water in the first sewage tank can be discharged into the sewer at one time, which plays a role in flushing the sewage discharge channel and the sewer.

[0105] like Figure 15 As shown, in some embodiments of the present invention, the control method further includes: S108, after the sewage discharge channel has been open for a fourth preset time, a closing signal is sent to the sewage discharge channel and the sewage discharge channel is controlled to be in a closed state. After the spray assembly has rinsed the inner wall of the first sewage tank for a third preset time, an opening signal is sent to the sewage discharge channel and the sewage discharge channel is controlled to be in an open state. At this time, the sewage generated in the first sewage tank after the second spray can be discharged to the outside of the base station, thereby completing the cleaning of the first sewage tank. After the sewage discharge channel has been open for a fourth preset time, a closing signal is sent to the sewage discharge channel and the sewage discharge channel is controlled to be in a closed state. After the sewage discharge channel has been open for a fourth preset time, it is ensured that the first sewage tank is in a dry state. At this time, the controller can move the sewage discharge channel from the open position to the closed position, which can prevent the smell of sewer or insects from coming up along the sewage discharge channel. The fourth preset time can be T4, and T4 can satisfy: 3min < T4 < 60min. By setting the fourth preset time within the above range, the water in the first sewage tank can be completely discharged, so that the first sewage tank is in a dry state.

[0106] The cleaning system according to the present invention is briefly described below.

[0107] The cleaning system according to the present invention includes a base station and a control module. The control module can control the base station according to the control method of the above embodiments. Since the control module can control the base station according to the control method of the above embodiments, the cleaning system can realize intelligent control of the base station, providing convenience for users.

[0108] Based on the same inventive concept, another embodiment of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements all the steps of the control method for the base station of the cleaning equipment described above, such as acquiring an opening signal and a closing signal of the sewage discharge channel, and controlling the sewage discharge channel to switch between an open state and a closed state based on the opening signal and the closing signal.

[0109] It is understood that the refined and extended functions that the computer program can execute can be referred to the description of the above embodiments.

[0110] Furthermore, the logical instructions in the aforementioned memory can be implemented as software functional units and sold or used as independent products, and can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.
