Base station and cleaning system control method

Abstract

The invention relates to the technical field of water replenishing, and provides a base station and a cleaning system control method. Comprising a liquid supply system, the liquid supply system comprises a main flow path, a liquid supplementing device, a backflow branch and a control device, a second flow path is matched with cleaning equipment, and the liquid supplementing device is connected to the main flow path. One end of the backflow branch is communicated with the main flow path, and the other end is communicated with the liquid supplementing device. The control device is installed at the intersection of the backflow branch and the main flow path and located on the downstream of the liquid supplementing device. When the cleaning equipment does not complete liquid supplementation on the base station, the cleaning equipment is configured to be disconnected from the base station in the liquid supplementation process so that the control device is configured to be opened when the water pressure of the second flow channel is larger than a preset value, and then at least part of liquid in the main flow channel enters the backflow branch; and therefore, the liquid circularly flows in a loop formed by the liquid supplementing device and the backflow branch. The water pressure of the second flow channel is effectively reduced, and the situation that the cleaning equipment is difficult to match with the base station due to overlarge water pressure of the second flow channel is avoided.

Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a base station and a cleaning system control method. Background Technology

[0002] With the development of technology and the improvement of people's quality of life, cleaning equipment is increasingly used in people's lives, greatly reducing the burden of manpower.

[0003] Taking floor scrubbers as an example, they are usually equipped with a base station, which can be placed on the scrubber after it finishes cleaning. The base station can charge the scrubber and also refill its water tank. However, current base station water refilling is too rigid, only able to perform the simple water refill action, and it is difficult to handle some special usage situations. Therefore, cleaning equipment with automatic water refilling actually has a poor user experience. Summary of the Invention

[0004] This application provides a base station and cleaning system control method that is more intelligent and can control and respond to special usage scenarios of cleaning equipment, thereby effectively improving the user experience.

[0005] This application provides a base station for carrying cleaning equipment, including:

[0006] A liquid supply system for supplying liquid to the cleaning equipment;

[0007] The liquid supply system includes:

[0008] A replenishment device for supplying liquid from the liquid supply system to the cleaning equipment;

[0009] The main flow path includes a first flow channel and a second flow channel. The first flow channel is located upstream of the replenishment device and is connected to the liquid supply system. The second flow channel is located downstream of the replenishment device. When the cleaning equipment is configured on the base station, the second flow channel is connected to the cleaning equipment.

[0010] A return branch, one end of which is connected to the second flow channel and the other end of which is connected to the first flow channel;

[0011] A control device is installed at the intersection of the return branch and the second flow channel;

[0012] When the cleaning equipment is configured to disconnect from the base station during the replenishment process, the control device is configured to open when the water pressure in the second flow channel is greater than a preset value, thereby allowing at least a portion of the liquid in the second flow channel to enter the return branch and then enter the first flow channel, and subsequently re-enter the control device.

[0013] In order to provide users with a better user experience, many companies have started to use base stations to replenish or change the water in cleaning equipment. However, the water replenishment solutions on the market are very rigid. They can only simply detect whether there is water in the clean water tank and start replenishing water when there is no water.

[0014] However, in actual use, many unexpected scenarios may occur. For example, during the water replenishment process, the user may suddenly remove the machine that is replenishing water. At this time, the machine may not have recognized that the machine has been removed or may not have had time to control the replenishment device to stop, causing the replenishment device to continue replenishing water. Since the water inlet is usually equipped with a one-way valve, the water replenishment pipe will be quickly blocked if water is still being replenished at this time.

[0015] However, when the user puts the cleaning equipment back on the base station after using it, the cleaning equipment cannot open the valve because the pipe after the one-way valve is blocked by water, thus preventing the water replenishment from continuing.

[0016] The base station provided in this application embodiment features a return branch connected in parallel with the replenishment device in the liquid supply system, with both ends of the return branch connected to the main flow path. A control device is installed at the intersection of the return branch and the main flow path. When the water pressure in the second flow channel exceeds a preset value, the control device opens the return branch, allowing liquid from the main flow path to enter the return branch. The liquid circulates along the return path and through the replenishment device; even if the replenishment device continues to supply liquid, the liquid will continue to circulate without clogging the pipes.

[0017] In other words, when the cleaning equipment is temporarily removed during the replenishment process, the opening at the replenishment device closes, but the replenishment device continues to supply liquid, increasing the water pressure in the second channel. At this time, the control device detects the increased water pressure in the second channel and can open the return branch, allowing some liquid to flow into the return branch and circulate in the loop formed by the return branch and the replenishment device. This effectively reduces or avoids liquid concentration in the second channel, significantly reducing the amount of water in it. It also effectively lowers the water pressure in the second channel, preventing situations where excessive water pressure in the second channel makes it difficult for the cleaning equipment to work with the base station. This allows the cleaning equipment to better cooperate with the base station, effectively improving the user experience.

[0018] In one possible implementation, the control device includes a first interface, a second interface, and a third interface;

[0019] The first interface is connected to the output port of the replenishment device, the second interface is connected to the second flow channel, and the third interface is connected to the return branch.

[0020] When the water pressure in the second flow channel is less than or equal to the preset value, the first interface is connected to the second interface, and the liquid flows from the first interface to the second interface, and then flows through the second interface to the second flow channel.

[0021] When the water pressure in the second flow channel is greater than the preset value, the first interface and the third interface are in communication, and the liquid flows from the first interface to the third interface and then flows into the return branch through the third interface.

[0022] By ensuring the three interfaces of the control device conform to the above structure, when the cleaning equipment removes liquid during replenishment, increasing the water pressure in the second channel, some liquid can flow into the return branch, effectively reducing or preventing liquid accumulation in the second channel. This effectively reduces the amount of water in the second channel and lowers its water pressure. Consequently, the cleaning equipment can better cooperate with the base station, effectively improving the user experience.

[0023] In one possible implementation, the liquid supply system further includes a first detection element installed on the main flow path, the first detection element being used to detect the flow signal of the main flow path.

[0024] When the liquid replenishment device is activated to supply liquid to the cleaning equipment, if there is a water outage or the water tank in the base station is empty, the liquid replenishment device will run dry, which can damage it. In this situation, the first detection element can promptly detect the absence of liquid flow in the main flow path, allowing the system to shut down the liquid replenishment device in a timely manner. This effectively reduces the duration of idling and prevents damage caused by prolonged idling, thus significantly improving the protection of the liquid replenishment device.

[0025] In one possible implementation, the first detection element is installed between the first flow channel and the replenishment device.

[0026] In other words, the first detection element is positioned close to the first flow channel. This allows the first detection element to start detecting the water flow signal as soon as it approaches the first flow channel, enabling it to quickly and accurately detect the water flow in the main flow path. This reduces the delay of the main flow signal and effectively improves the detection efficiency and accuracy of the main flow signal detection.

[0027] In one possible implementation, the base station further includes a second detection element for matching with a detection element on the cleaning equipment to detect whether the cleaning equipment is in place.

[0028] When the second detection device detects that the cleaning equipment is in place, the liquid replenishment device can be activated to deliver liquid to the cleaning equipment in the second flow channel. When the second detection device does not detect the cleaning equipment, the operation of the liquid replenishment device can be stopped to prevent the liquid replenishment device from starting when the cleaning equipment is not in place, which could damage the base station, the liquid supply system, and the liquid replenishment device. This helps to improve the protection of the base station, the liquid supply system, and the liquid replenishment device.

[0029] In one possible implementation, the second detection element is a Hall sensor. Hall sensors have high sensitivity and fast response time, which can effectively improve the detection accuracy and speed up the response of the second detection element.

[0030] In one possible implementation, the base station further includes a charging electrode for engaging with electrodes on the cleaning device to charge the cleaning device.

[0031] By engaging the charging electrodes with the electrodes on the cleaning device, the device can be charged. This effectively reduces or prevents the cleaning device from running out of power, thus extending its runtime.

[0032] In one possible implementation, a controller is also included, which is installed in the base station;

[0033] The controller is electrically connected to the liquid replenishment device and the first detection element. When the liquid replenishment device is turned on, if the first detection element does not detect a water flow signal, the controller will turn the liquid replenishment device off.

[0034] When the liquid replenishment device is already operating and supplying liquid to the cleaning equipment, if the first detection element does not detect a water flow signal in the main flow path, it indicates that there is no water source in the first flow channel, indicating a water outage or that the base station's water supply tank is empty. In this case, the controller can promptly shut down the liquid replenishment device to prevent it from running idle for extended periods. This effectively reduces or avoids damage caused by prolonged idling of the liquid replenishment device, significantly improving its protection.

[0035] In one possible implementation, the controller is also electrically connected to the second detection element, and the controller is also configured to control the opening or closing of the fluid replenishment device based on the in-place signal detected by the second detection element;

[0036] When the second detection device detects that the cleaning equipment is in place, the controller can activate the liquid replenishment device to deliver liquid to the cleaning equipment in the second flow channel. When the second detection device does not detect the cleaning equipment, the controller can stop the operation of the liquid replenishment device to prevent it from starting when the cleaning equipment is not in place, which could damage the base station, the liquid supply system, and the liquid replenishment device. This improves the protection of the base station, the liquid supply system, and the liquid replenishment device.

[0037] Alternatively, the controller is also electrically connected to the charging electrode, and the controller is also configured to activate the replenishment device after the charging electrode engages with the electrode on the cleaning device, and deactivate the replenishment device after the charging electrode disconnects from the electrode on the cleaning device.

[0038] The compatibility between the charging electrode and the electrode on the cleaning device can be determined by observing the interaction between them. For example, when the charging electrode and the electrode on the cleaning device are compatible, it indicates that the cleaning device is compatible with the base station. In this case, liquid replenishment can be performed, and the controller can activate the liquid replenishment device to replenish the liquid for the cleaning device. Conversely, when the charging electrode and the electrode on the cleaning device are not compatible, it indicates that the cleaning device is not compatible with the base station. In this case, the controller will not activate the liquid replenishment device to prevent damage to the base station and the liquid supply system caused by the liquid replenishment device activating when the cleaning device is not compatible with the base station, thus improving the protection of the base station and the liquid replenishment system.

[0039] At the same time, it should be emphasized that in this patent solution, it is more suitable to use the signal of the charging electrode to control the liquid replenishment device. Specifically, in previous base station products, everyone knows that the charging signal can be used to feed back the position status and then control the action of the liquid replenishment device, but no company dares to use this method.

[0040] Because the detection delay of this method is too long, or its feedback response speed is too slow, it is easy to cause the water replenishment to become blocked. However, the solution of this application is different. Since this patent adopts a circulating flow method, using the charging signal for feedback becomes the most suitable method, because its cost is very low and there is no need to add an additional detection device. Moreover, since this solution completely solves the above problems, even if the feedback time is relatively delayed, it will not cause problems. That is to say, the solution provided by this patent not only solves the problem of water replenishment itself, but also optimizes the entire base station system.

[0041] In one possible implementation, the liquid supply system further includes a connector installed at the intersection of the return branch and the main flow path, and located upstream of the replenishment device;

[0042] The inlet of the replenishment device is connected to the first flow channel and the return branch through the connecting member.

[0043] The connecting component links the replenishment device, the main flow path, and the return branch, allowing liquid to flow between these components and improving the flowability of the liquid. This ensures that when the cleaning equipment is removed before replenishment is complete, the liquid can circulate through the connecting component in the loop formed by the replenishment device and the return branch, effectively enhancing the smoothness of liquid flow.

[0044] In one possible implementation, the connector includes a fourth interface, a fifth interface, and a sixth interface that are interconnected.

[0045] The fourth interface is connected to the input port of the replenishment device, the fifth interface is connected to the first flow channel, and the sixth interface is connected to the return branch.

[0046] The three interfaces of the connector allow the liquid supply system to flow in different directions under different conditions. This effectively reduces or prevents liquid accumulation in the second channel, which would increase the water pressure there. By reducing the water pressure in the second channel, the system can facilitate the cleaning equipment's re-operation with the base station.

[0047] In one possible implementation, the base station further includes:

[0048] The base shell has a brush plate cleaning chamber and a roller brush cleaning chamber. The brush plate cleaning chamber is used for self-cleaning of the brush plate, and the roller brush cleaning chamber is used for self-cleaning of the roller brush.

[0049] A drainage component is installed on the base shell. The brush plate cleaning chamber and the roller brush cleaning chamber are connected through the drainage component, and the sewage in the brush plate cleaning chamber flows into the roller brush cleaning chamber through the drainage component.

[0050] The base shell has a liquid accumulation cavity, and the drainage element is at least partially located in the liquid accumulation cavity. The bottom wall of the liquid accumulation cavity has a third detection element and a fourth detection element. The liquid accumulation cavity is used to collect overflow water at the drainage element. When the overflow water in the liquid accumulation cavity conducts the third detection element and the fourth detection element, the cleaning device stops the self-cleaning of the brush plate or the roller brush.

[0051] By incorporating a liquid accumulation chamber within the base shell and positioning the drainage component on the bottom wall of this chamber, the third and fourth detection components on the bottom wall of the liquid accumulation chamber can be quickly activated when water overflows from the drainage component. This allows the system to rapidly stop the self-cleaning action of the brush plate or roller, effectively preventing continuous water overflow that could damage the base station and significantly improving its protection.

[0052] In one possible implementation, the base shell also has a liquid replenishment connector for use with the cleaning equipment;

[0053] The replenishment connector is connected to the second flow channel so that the liquid in the main flow path flows into the water tank of the cleaning equipment through the replenishment connector;

[0054] The fluid replenishment connector is located at least partially within the fluid accumulation chamber, which is also used to collect overflow water from the fluid replenishment connector. When the overflow water in the fluid accumulation chamber connects the third and fourth detection elements, the fluid replenishment device stops working.

[0055] By embedding at least a portion of the liquid replenishment connector in the bottom wall of the liquid accumulation chamber, the third and fourth detection elements on the bottom wall of the chamber can be quickly activated when water overflows from the connector. This allows the system to rapidly shut down the liquid replenishment device, stopping the replenishment process. This effectively prevents continuous water overflow from the connector from damaging the base station, thus significantly improving base station protection.

[0056] In one possible implementation, the base station further includes a base shell, which is further formed with a roller brush cleaning chamber, a first support platform, and a second support platform.

[0057] The roller brush cleaning chamber is used for self-cleaning of the roller brush. The first support platform and the second support platform are respectively located at both ends of the roller brush cleaning chamber. The first support platform and the second support platform are respectively used to support and raise the roller brush so that there is a gap between the roller brush and the bottom wall of the roller brush cleaning chamber.

[0058] The gap between the roller brush and the roller brush cleaning chamber can reduce the pressure on the roller brush surface, which helps to improve the cleaning effect of the roller brush.

[0059] A second aspect of this application provides a method for controlling a cleaning system, the cleaning system including cleaning equipment and a base station.

[0060] The base station includes a liquid supply system (110) for supplying liquid to the cleaning equipment;

[0061] The liquid supply system includes:

[0062] A replenishment device for supplying liquid from the liquid supply system to the cleaning equipment;

[0063] The main flow path includes a first flow channel and a second flow channel. The first flow channel is located upstream of the replenishment device and is connected to the liquid supply system. The second flow channel is located downstream of the replenishment device. When the cleaning equipment is configured on the base station, the second flow channel is connected to the cleaning equipment.

[0064] A return branch, one end of which is connected to the second flow channel and the other end of which is connected to the first flow channel;

[0065] A control device is installed at the intersection of the return branch and the second flow channel, and is located downstream of the replenishment device.

[0066] The control method includes:

[0067] After the cleaning equipment is placed in the base station, the liquid replenishment device is activated to replenish the cleaning equipment with liquid;

[0068] When the cleaning equipment is configured to disconnect from the base station's liquid replenishment, the control device is configured to open when the water pressure in the second flow channel is greater than a preset value, thereby allowing at least a portion of the liquid in the second flow channel to enter the return branch and then the first flow channel, and subsequently re-enter the control device.

[0069] Through the control method described above, when the cleaning equipment is removed before completing the liquid replenishment process, the liquid supply system can respond quickly, directing the liquid into the return branch to circulate within the loop formed by the replenishment device and the return branch. This effectively reduces or prevents liquid concentration in the second flow channel, thus minimizing the water volume there. It also effectively lowers the water pressure in the second flow channel, preventing situations where excessive water pressure in the second channel makes it difficult for the cleaning equipment to work with the base station. This allows the cleaning equipment to better cooperate with the base station, effectively improving the user experience.

[0070] In one possible implementation, the base station further includes a first detection element installed between the first flow channel and the replenishment device, the first detection element being used to detect the water flow signal of the main flow path, and the control method further includes:

[0071] When the first detection device detects no water flow signal in the main flow path, the liquid replenishment device is turned off.

[0072] After the replenishment device has been activated and is supplying liquid to the cleaning equipment, if the first detection element does not detect a water flow signal in the main flow path, it indicates that there is no water source in the first flow channel, indicating a water outage or that the base station's water supply tank is empty. In this case, the system can promptly shut down the replenishment device to prevent it from running idle for extended periods. This effectively reduces or avoids damage caused by prolonged idling of the replenishment device, significantly improving its protection.

[0073] In one possible implementation, the base station includes a base shell with a liquid accumulation cavity formed therein, the liquid accumulation cavity having a third detection element and a fourth detection element, the cleaning device including a brush, and the control method further including:

[0074] When there is water in the fluid accumulation chamber, so that the third detection element and the fourth detection element are electrically connected, and when the fluid replenishment device is working, the fluid replenishment device is turned off;

[0075] Using the above control method, when water overflows from the replenishment connector, causing the third and fourth detection elements on the bottom wall of the liquid accumulation chamber to become conductive, the system can quickly shut down the replenishment device to stop the replenishment operation. This effectively prevents continuous water overflow at the replenishment connector from damaging the base station, thus significantly improving the protection of the base station.

[0076] Alternatively, when water is present in the fluid accumulation chamber, the third detection element and the fourth detection element may be electrically connected, and the self-cleaning of the brush disk may be stopped during self-cleaning.

[0077] Through the above control method, when water overflows from the drainage component and causes the third and fourth detection components on the bottom wall of the liquid accumulation chamber to become conductive, the system can quickly stop the self-cleaning of the brush plate or roller brush, thereby effectively preventing continuous water overflow from damaging the base station and effectively improving the protection of the base station.

[0078] In one possible implementation, a second detection element is further included, which is used to match a detection element on the cleaning device, and the control method further includes:

[0079] Once the second detection element matches the detection element on the cleaning equipment, the liquid replenishment device is activated.

[0080] Once the second detection element matches the detection element on the cleaning equipment, indicating that the cleaning equipment is in place, the liquid replenishment device can be activated to deliver liquid to the cleaning equipment in the second flow channel.

[0081] In one possible implementation, the control method further includes:

[0082] When the second detection element fails to detect the detection element of the cleaning equipment, the liquid replenishment device is shut down.

[0083] When the second detection device fails to detect the cleaning equipment, it indicates that the cleaning equipment is separated from the base station and is not in place. In this case, the operation of the liquid replenishment device can be stopped to prevent it from activating while the cleaning equipment is not in place, which could damage the base station, the liquid supply system, and the liquid replenishment device. This improves the protection of the base station, the liquid supply system, and the liquid replenishment device.

[0084] In one possible implementation, the base station further includes a charging electrode for engaging with electrodes on the cleaning device to charge the cleaning device, and the control method further includes:

[0085] When the charging electrode mates with the electrode on the cleaning device, the liquid replenishment device is activated;

[0086] When the charging electrode is disconnected from the electrode on the cleaning device, the liquid replenishment device is turned off.

[0087] By determining the matching status between the charging electrode and the electrode on the cleaning equipment, it is possible to ascertain whether the cleaning equipment is in place. This allows for the control of the liquid replenishment device's activation or deactivation based on the matching status. This effectively improves the reliability of the liquid replenishment device's operation, preventing it from activating when the cleaning equipment is not in place, thus avoiding damage to the base station, liquid supply system, and liquid replenishment device. This enhances the protection of the base station, liquid supply system, and liquid replenishment device. Attached Figure Description

[0110] As described in the background section above, floor scrubbers are typically equipped with a base station, which can be placed on the scrubber after it has finished cleaning. The base station can charge the scrubber and also replenish its water tank. Specifically, a refill device can be installed on the base station, and the scrubber can work in conjunction with the refill device to allow water from the base station to be delivered to the scrubber's water tank.

[0111] However, in actual use, users often remove the floor scrubber suddenly during the base station water replenishment process due to operating habits or temporary needs. At this time, the water replenishment pump in the base station has not completely stopped working, resulting in instantaneous high pressure in the water replenishment pipeline and also putting the liquid replenishment device under high pressure. As a result, when the user places the floor scrubber back on the base station, the excessive water pressure in the water replenishment pipeline and at the liquid replenishment device makes it difficult to smoothly match the floor scrubber with the liquid replenishment device, thus reducing the user experience.

[0112] To address the aforementioned issues, this application provides a base station that incorporates a return branch connected in parallel with a replenishment device in its liquid supply system, with both ends of the return branch connected to the main flow path. A control device is positioned at the intersection of the return branch and the main flow path. When the water pressure in the second channel exceeds a preset value, the control device opens the return branch, allowing liquid from the main flow path to enter it. Thus, when the cleaning equipment is temporarily removed during replenishment, the opening at the replenishment device closes, but the replenishment device continues to supply liquid, increasing the water pressure in the second channel. Upon detecting this increased pressure, the control device opens the return branch, allowing some liquid to flow into it and circulate within the loop formed by the return branch and the replenishment device. This effectively reduces or prevents liquid concentration in the second channel, minimizing the amount of water in the channel. It also effectively lowers the water pressure in the second channel, preventing situations where excessive pressure in the second channel makes it difficult for the cleaning equipment to work with the base station. This allows the cleaning equipment to better cooperate with the base station, effectively improving the user experience. To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0113] Figure 1 This is a schematic diagram of the structure of a base station provided in an embodiment of this application. Figure 2 This is a schematic diagram of a liquid supply system installed in a base station according to an embodiment of this application. Figure 3 A schematic diagram of a liquid supply system provided in an embodiment of this application.

[0114] This application provides a base station that can be used to carry cleaning equipment, which can be a household handheld floor scrubber. The cleaning equipment is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a floor, wall, or the surface of an object to be cleaned with different degrees of roughness. This application does not specifically limit the type of surface to be cleaned.

[0115] The cleaning equipment may include a floor brush and a main body, which are rotatably connected. For example, the floor brush may be rotatably connected to the bottom of the main body. During the cleaning process, the user can hold the main body and swing it to rotate the floor brush relative to the main body, allowing the floor brush to travel to different areas (e.g., under tables, under cabinets, etc.). The floor brush cleans the surface to be cleaned by contacting and rubbing against it.

[0116] A floor brush may also include a housing, a roller brush, and wheels. The housing is the main supporting structure of the floor brush, and the roller brush and wheels can both be mounted in the housing. For example, the housing may have a receiving cavity, the roller brush may be located in the receiving cavity of the housing, and the roller brush may rotate about its own axial direction.

[0117] When the cleaning equipment is performing cleaning operations, the roller brush contacts the surface to be cleaned. A motor installed inside the roller brush drives it to rotate at high speed, allowing the brush to rub against the surface and clean it. The wheels contact the surface and roll along it, assisting the cleaning equipment in moving across the surface and improving the stability of the brush.

[0118] The cleaning equipment may also include a clean water tank and a wastewater tank. Water from the clean water tank can be supplied to the roller brush to wet it and soften the stains on the surface to be cleaned, thus making the stains easier to remove. After use, the clean water becomes wastewater and can be transferred to the wastewater tank for centralized treatment.

[0119] See Figure 1 and Figure 2 As shown, the base station 100 includes a liquid supply system 110, which can be used to supply liquid to cleaning equipment. For example, the liquid supply system 110 can provide clean water to the cleaning equipment.

[0120] See Figure 2 As shown, the liquid supply system 110 may include a main flow path 111, which includes a first flow channel 1111 and a second flow channel 1112. The first flow channel 1111 is located upstream of the liquid replenishment device 112 and is connected to the liquid supply system. The second flow channel 1112 is located downstream of the liquid replenishment device 112. When the cleaning equipment is configured on the base station, the second flow channel 1112 is connected to the cleaning equipment and can cooperate with the cleaning equipment to supply liquid to the cleaning equipment. For example, the second flow channel 1112 may be equipped with a liquid replenisher, and the cleaning equipment can cooperate with the liquid replenisher so that the liquid at the end of the main flow path 111 can enter the cleaning equipment through the liquid replenisher.

[0121] The first flow channel 1111 can be connected to the water source of the base station 100. For example, the base station 100 can have a water supply tank 150, and the first flow channel 1111 can be connected to the water supply tank 150 so that the water in the water supply tank 150 can flow through the main flow channel 111 to the cleaning equipment to supply clean water for the cleaning equipment. Alternatively, the base station 100 can also be a tankless type. In this case, the first flow channel 1111 can be connected to a faucet so that the water from the faucet can flow through the main flow channel 111 to the cleaning equipment to supply clean water for the cleaning equipment. In this embodiment, the type of base station 100 is not limited.

[0122] See Figure 2As shown, the base station 100 may further include a liquid replenishment device 112, which may be connected to the main flow path 111. The liquid replenishment device 112 may be used to deliver liquid to the end of the main flow path 111 to supply liquid to the cleaning equipment. For example, the liquid replenishment device 112 may be a water pump, which may provide power for the liquid flow in the main flow path 111 so that the liquid is delivered to the cleaning equipment under the power of the water pump.

[0123] The liquid supply system 110 may further include a return branch 116 and a control device 113. One end of the return branch 116 may be connected to the main flow path 111, and the other end may be connected to the replenishment device 112. Furthermore, the return branch 116 may be connected in parallel with the replenishment device 112. The control device 113 may be installed at the intersection of the return branch 116 and the main flow path 111, and is located downstream of the replenishment device 112. That is, it can be understood that the parts connecting the return branch 116 and the main flow path 111 are located at both ends of the replenishment device 112, and the control device 113 is installed between the replenishment device 112 and the second flow channel 1112.

[0124] When the cleaning equipment has not yet completed replenishing the liquid on the base station 100, the cleaning equipment can be configured to disconnect from the base station 100 during the replenishment process, so that the control device 113 is configured to open when the water pressure in the second flow channel 1112 is greater than a preset value, thereby allowing at least a portion of the liquid in the main flow channel 111 to enter the return branch 116, so that the liquid circulates in the loop formed by the replenishment device 112 and the return branch 116.

[0125] In other words, if the cleaning equipment is temporarily removed while it is still replenishing liquid at the base station 100, the liquid replenishment opening at the end of the main flow path 111 is closed, while the liquid replenishment device 112 continues to supply water, causing the water pressure at the end of the main flow path 111 to exceed a preset value. At this time, the control device 113 can be opened, allowing at least a portion of the liquid in the main flow path 111 to enter the return branch 116, so that the liquid circulates in the loop formed by the liquid replenishment device 112 and the return branch 116. The aforementioned preset water pressure can be understood as being greater than the water pressure of the main flow path 111 under normal operating conditions.

[0126] This allows some liquid to be diverted from the return branch 116, effectively reducing or preventing liquid concentration in the second flow channel 1112. It also effectively reduces the water volume at the end of the main flow channel 111 and lowers the water pressure there, allowing the cleaning equipment to better cooperate with the base station 100 and significantly improving the user experience.

[0127] The base station 100 provided in this application embodiment includes a return branch 116 connected in parallel with the replenishment device 112 in the liquid supply system 110, with both ends of the return branch 116 connected to the main flow path 111. A control device 113 is installed at the intersection of the return branch 116 and the main flow path 111. When the water pressure at the end of the main flow path 111 exceeds a preset value, the control device 113 can open the return branch 116, allowing liquid from the main flow path 111 to enter the return branch 116. Thus, when the cleaning equipment is temporarily removed during replenishment, the opening at the replenishment device closes, but the replenishment device 112 continues to supply liquid, increasing the water pressure at the end of the main flow path 111. At this time, the control device 113 detects the increased water pressure at the end of the main flow path 111 and can open the return branch 116, allowing some liquid to flow into the return branch 116 and circulate in the loop formed by the return branch 116 and the replenishment device 112. This effectively reduces or prevents liquid concentration in the second flow channel 1112, thus reducing the water volume at the end of the main flow path 111. It also effectively lowers the water pressure at the end of the main flow path 111, preventing situations where excessive water pressure at the end of the main flow path 111 makes it difficult for the cleaning equipment to match the base station 100. This allows the cleaning equipment to better cooperate with the base station 100, effectively improving the user experience.

[0128] Figure 4 This is a schematic diagram of the structure of a control device provided in an embodiment of this application.

[0129] See Figure 4 As shown, the control device 113 may include a first interface 1131, a second interface 1132 and a third interface 1133. The first interface 1131 can be connected to the output port of the replenishment device 112, the second interface 1132 can be connected to the end of the main flow path 111, and the third interface 1133 can be connected to the return branch 116.

[0130] When the water pressure in the second flow channel 1112 is less than or equal to a preset value, the first port 1131 can be connected to the second port 1132, allowing liquid to flow from the first port 1131 to the second port 1132, and then through the second port 1132 to the second flow channel 1112. At this time, the liquid can enter the cleaning equipment through the replenishment device at the end of the main flow channel 111 to supply liquid to the cleaning equipment.

[0131] When the water pressure in the second flow channel 1112 exceeds a preset value, the first port 1131 can communicate with the third port 1133. Liquid can flow from the first port 1131 to the third port 1133 and then into the return branch 116 through the third port 1133. The liquid flowing into the return branch 116 can flow back into the replenishment device 112, thus circulating in the loop formed by the replenishment device 112 and the return branch 116.

[0132] By ensuring the three interfaces of the control device 113 meet the aforementioned structure, when the cleaning equipment removes liquid during replenishment, increasing the water pressure at the end of the main flow path 111, some liquid can flow into the return branch path 116, effectively reducing or preventing liquid concentration in the second flow channel 1112. This effectively reduces the water volume at the end of the main flow path 111 and lowers the water pressure there. Consequently, the cleaning equipment can better cooperate with the base station 100, effectively improving the user experience.

[0133] See also Figure 2 As shown, the liquid supply system 110 may further include a first detection element 114, which may be installed on the main flow path 111 and used to detect the flow signal of the main flow path 111. For example, the first detection element 114 may be a photoelectric detection element, which can detect the flow signal in the main flow path 111 in real time to determine whether liquid is flowing through the main flow path 111.

[0134] When the liquid replenishment device 112 starts working to supply liquid to the cleaning equipment, if there is a water outage or the water supply tank 150 in the base station 100 is empty, the liquid replenishment device 112 will run dry, which may damage the liquid replenishment device 112. At this time, the first detection element 114 can detect in time that no liquid is flowing through the main flow path 111, so that the system can shut down the liquid replenishment device 112 in time, thereby effectively reducing the dry running time of the liquid replenishment device 112. This can effectively reduce or avoid damage caused by prolonged dry running of the liquid replenishment device 112, and effectively improve the protection of the liquid replenishment device 112.

[0135] See also Figure 2 As shown, the first detection element 114 can be installed between the first flow channel 1111 and the liquid replenishment device 112. That is, the first detection element 114 is set close to the first flow channel 1111, so that the first detection element 114 can start detecting the water flow signal from the moment it approaches the first flow channel 1111. This allows the first detection element 114 to quickly and accurately detect the water flow condition of the main flow path 111, reduce the delay of the water flow signal in the main flow path 111, and thus effectively improve the detection efficiency of the first detection element 114 and improve the accuracy of the water flow signal detection in the main flow path 111.

[0136] The base station 100 may also include a second detection element, which can be matched with a detection element on the cleaning equipment to detect whether the cleaning equipment is in place. For example, when the second detection element detects that the cleaning equipment is in place, the liquid replenishment device 112 can be activated to deliver liquid to the cleaning equipment at the end of the main flow path 111. When the second detection element does not detect the cleaning equipment, the operation of the liquid replenishment device 112 can be stopped to prevent the liquid replenishment device 112 from starting when the cleaning equipment is not in place, thereby preventing damage to the base station 100, the liquid supply system 110, and the liquid replenishment device 112, and improving the protection of the base station 100, the liquid supply system 110, and the liquid replenishment device 112.

[0137] The second detection component can be a Hall sensor, which can be matched with the magnetic component on the cleaning equipment. When the cleaning equipment is placed on the base station 100, the Hall sensor can detect the magnetic component on the cleaning equipment, thereby determining that the cleaning equipment is in place. The system can then activate the liquid replenishment device 112 to supply liquid to the cleaning equipment.

[0138] Conversely, when the Hall sensor does not detect the magnetic component on the cleaning device, it indicates that the cleaning device is not placed on the base station 100. In this case, the system can shut down the replenishment device 112 to reduce or avoid damage to the liquid supply system 110 caused by the operation of the replenishment device 112.

[0139] Hall effect sensors have high sensitivity and fast response time, which can effectively improve the detection accuracy of the second detection device and speed up its response.

[0140] See also Figure 1 and Figure 2 As shown, the base station 100 may further include a charging electrode 120, which can be used to cooperate with the electrodes on the cleaning device to charge the cleaning device. For example, the charging electrode 120 may include a positive electrode and a negative electrode. By cooperating with the electrodes on the cleaning device, the cleaning device can be charged. This can effectively reduce or avoid the cleaning device from running out of power, and can effectively extend the battery life of the cleaning device.

[0141] The base station 100 may also include a controller, which may be installed on the base station 100. The controller may be electrically connected to the liquid replenishment device 112 and the first detection element 114. When the liquid replenishment device 112 is controlled to be turned on, if the first detection element 114 does not detect a water flow signal, the liquid replenishment device 112 will be controlled to be turned off.

[0142] That is, when the replenishment device 112 is already operating and supplying liquid to the cleaning equipment, if the first detection element 114 does not detect a water flow signal in the main flow path 111, it indicates that there is no water source in the first flow channel 1111, and it is in a water outage state, or that the water supply tank of the base station 100 is empty. At this time, the controller can promptly shut off the replenishment device 112 to prevent it from running idle for an extended period. This effectively reduces or avoids damage to the replenishment device 112 due to prolonged idling, thus significantly improving the protection of the replenishment device 112.

[0143] The controller can also be electrically connected to the second detection element, and can also be used to control the opening or closing of the liquid replenishment device 112 based on the positioning signal detected by the second detection element. For example, when the second detection element detects that the cleaning equipment is in place, the controller can activate the liquid replenishment device 112 so that it can deliver liquid to the cleaning equipment at the end of the main flow path 111. When the second detection element does not detect the cleaning equipment, the controller can stop the operation of the liquid replenishment device 112 to prevent the liquid replenishment device 112 from starting when the cleaning equipment is not in place, thereby preventing damage to the base station 100, the liquid supply system 110, and the liquid replenishment device 112, and improving the protection of the base station 100, the liquid supply system 110, and the liquid replenishment device 112.

[0144] The controller can also be electrically connected to the charging electrode 120. The controller can also be used to start the replenishment device 112 after the charging electrode 120 engages with the electrode on the cleaning device, and to shut down the replenishment device 112 after the charging electrode 120 disconnects from the electrode on the cleaning device.

[0145] The compatibility between the charging electrode 120 and the electrode on the cleaning device can also determine whether the cleaning device is compatible with the base station 100. For example, when the charging electrode 120 is compatible with the electrode on the cleaning device, it indicates that the cleaning device is compatible with the base station 100. In this case, liquid replenishment can be performed, and the controller can activate the liquid replenishment device 112 to replenish the cleaning device. Conversely, when the charging electrode 120 is not compatible with the electrode on the cleaning device, it indicates that the cleaning device is not compatible with the base station 100. In this case, the controller will not activate the liquid replenishment device 112 to prevent damage to the base station 100 and the liquid supply system 110 caused by the liquid replenishment device 112 activating when the cleaning device is not compatible with the base station 100, thus improving the protection of the base station 100 and the liquid replenishment system.

[0146] See also Figure 2 As shown, the liquid supply system 110 may further include a connecting member 115, which can be installed at the intersection of the return branch 116 and the main flow path 111, and is located upstream of the replenishment device 112. The inlet of the replenishment device 112 can be connected to the first flow channel 1111 and the return branch 116 through the connecting member 115.

[0147] The connecting member 115 connects the liquid replenishment device 112, the main flow path 111, and the return branch path 116, allowing liquid to flow between the main flow path 111, the return branch path 116, and the liquid replenishment device 112 through the connecting member 115, thereby improving the flowability among the main flow path 111, the return branch path 116, and the liquid replenishment device 112. Thus, when the cleaning equipment is removed before liquid replenishment is completed, the liquid can circulate through the connecting member 115 in the loop formed by the liquid replenishment device 112 and the return branch path 116, effectively improving the smoothness of liquid flow.

[0148] Figure 5 This is a schematic diagram of a connecting element provided in an embodiment of this application.

[0149] See also Figure 5 As shown, the connecting element 115 may include a fourth interface 1151, a fifth interface 1152, and a sixth interface 1153 that are interconnected. The fourth interface 1151 can be connected to the input port of the replenishment device 112, the fifth interface 1152 can be connected to the first flow channel 1111, and the sixth interface 1153 can be connected to the return branch 116.

[0150] The fourth interface 1151, the fifth interface 1152, and the sixth interface 1153 are internally interconnected, allowing liquid to flow between them. For example, when the liquid supply system 110 is normally supplying liquid to the cleaning equipment, liquid can flow from the fifth interface 1152 into the connector 115, and from the fourth interface 1151 out of the connector 115 into the replenishment device 112 to supply liquid to the cleaning equipment. When the cleaning equipment is removed from the base station 100, liquid can flow into the return branch 116 at the control device 113, and then flow into the replenishment device 112 through the sixth interface 1153 and the fourth interface 1151 of the connector 115, thus circulating.

[0151] Through the three interfaces of the connector 115, the liquid supply system 110 allows the liquid to flow in different directions under different conditions. This effectively reduces or avoids liquid accumulation at the end of the main flow path 111, which would increase the water pressure at the end of the main flow path 111. This effectively reduces the water pressure at the end of the main flow path 111, making it easier for the cleaning equipment to cooperate with the base station 100 again.

[0152] Figure 6 This application provides a front view of a base station according to an embodiment of the present application. Figure 7 This is a front view schematic diagram of a fluid accumulation cavity installed in a base station, provided in an embodiment of this application. Figure 8 This is an isometric structural diagram of a liquid accumulation cavity installed in a base station, as provided in an embodiment of this application.

[0153] See also Figure 6 and Figure 7 As shown, the base station 100 may also include a base shell 130, which may have a brush plate cleaning chamber 131 and a roller brush cleaning chamber 132. The brush plate cleaning chamber 131 is used for self-cleaning of the brush plate, and the roller brush cleaning chamber 132 is used for self-cleaning of the roller brush.

[0154] Combination Figure 8 As shown, the base station 100 may further include a draining component 140, which can be installed on the base shell 130. The brush plate cleaning chamber 131 and the roller brush cleaning chamber 132 can be connected through the draining component 140, allowing wastewater in the brush plate cleaning chamber 131 to flow into the roller brush cleaning chamber 132 through the draining component 140. This allows the wastewater generated in the brush plate cleaning chamber 131 to be transported together with the wastewater in the roller brush cleaning chamber 132 to a wastewater tank for centralized treatment.

[0155] The base shell 130 may have a liquid collection chamber 133, at least a portion of the drainage member 140 may be located within the liquid collection chamber 133, and the bottom wall of the liquid collection chamber 133 may have a third detection member 1331 and a fourth detection member 1332. The liquid collection chamber 133 can be used to collect overflow water from the drainage member 140, and when the overflow water in the liquid collection chamber 133 connects the third detection member 1331 and the fourth detection member 1332, the cleaning equipment stops the self-cleaning of the brush plate or roller brush.

[0156] For example, the third detection element 1331 and the fourth detection element 1332 can be electrodes. When wastewater in the brush plate cleaning chamber 131 flows through the drain element 140 to the roller brush cleaning chamber 132, and leakage occurs at the drain element 140, the overflow water can be collected in the liquid accumulation chamber 133. As the liquid level in the liquid accumulation chamber 133 rises, the third detection element 1331 and the fourth detection element 1332 on the bottom wall of the liquid accumulation chamber 133 can become interconnected. At this time, the system can quickly stop the self-cleaning of the brush plate or roller brush to prevent the brush plate cleaning chamber 131 from continuing to generate wastewater, reducing or preventing continuous overflow of wastewater that could damage the base station 100.

[0157] By providing a liquid accumulation chamber 133 within the base shell 130 and positioning the drainage component 140 on the bottom wall of the liquid accumulation chamber 133, when water overflows from the drainage component 140, the third detection component 1331 and the fourth detection component 1332 on the bottom wall of the liquid accumulation chamber 133 can be quickly made conductive. This allows the system to quickly stop the self-cleaning of the brush plate or roller brush, effectively preventing continuous water overflow from damaging the base station 100 and significantly improving the protection of the base station 100.

[0158] See also Figure 6 and Figure 7As shown, the base shell 130 may also have a liquid replenishment connector 134 (also called a liquid replenisher), which can be used to cooperate with cleaning equipment. The liquid replenishment connector 134 can be connected to the second flow channel 1112 so that the liquid in the main flow channel 111 can flow into the water tank 150 of the cleaning equipment through the liquid replenishment connector 134.

[0159] Combination Figure 8 As shown, the liquid replenishment connector 134 can be located at least partially within the liquid accumulation chamber 133. The liquid accumulation chamber 133 can also be used to collect the overflow water at the liquid replenishment connector 134. When the overflow water in the liquid accumulation chamber 133 connects the third detection element 1331 and the fourth detection element 1332, the liquid replenishment device 112 stops working.

[0160] For example, during the process of liquid entering the cleaning equipment water tank 150 through the replenishment connector 134, if a leak occurs at the replenishment connector 134 and water overflows, the overflow water can be collected in the accumulation chamber 133. As the liquid level in the accumulation chamber 133 rises, the third detection element 1331 and the fourth detection element 1332 on the bottom wall of the accumulation chamber 133 can become interconnected. At this time, the system can quickly stop the operation of the replenishment device 112 to stop supplying liquid to the cleaning equipment, thereby preventing the brush cleaning chamber 131 from continuing to generate sewage and reducing or preventing continuous sewage overflow that could damage the base station 100.

[0161] By configuring at least a portion of the liquid replenishment connector 134 on the bottom wall of the liquid accumulation chamber 133, when water overflows from the liquid replenishment connector 134, the third detection element 1331 and the fourth detection element 1332 on the bottom wall of the liquid accumulation chamber 133 can be quickly made conductive. This allows the system to quickly shut down the liquid replenishment device 112 to stop the liquid replenishment operation. This effectively prevents continuous water overflow from the liquid replenishment connector 134 from damaging the base station 100, thus significantly improving the protection of the base station 100.

[0162] See Figure 6 and Figure 1 As shown, the base shell 130 may also have a first support platform 1321 and a second support platform 1322, which may be located at both ends of the roller brush cleaning chamber 132. The first support platform 1321 and the second support platform 1322 may be used to support and raise the roller brush, so that there is a gap between the roller brush and the bottom wall of the roller brush cleaning chamber 132.

[0163] The gap between the roller brush and the roller brush cleaning chamber 132 can reduce the pressure on the roller brush surface, which helps to improve the cleaning effect of the roller brush.

[0164] This application also provides a control method for a cleaning system, wherein the cleaning system can be any of the cleaning systems described above. The following describes the cleaning system control method provided by this application in detail with reference to the accompanying drawings.

[0165] Figure 9 This is a flowchart illustrating a control method provided in an embodiment of this application.

[0166] See Figure 9 As shown, the control method may include:

[0167] S101: After the cleaning equipment is placed on the base station 100, the liquid replenishment device 112 is activated to replenish the cleaning equipment with liquid;

[0168] S102: When the cleaning equipment is configured to disconnect from the base station's liquid replenishment so that the control device is configured to open when the water pressure in the second flow channel is greater than a preset value, the control device will allow at least a portion of the liquid in the second flow channel to enter the return branch and then enter the first flow channel, and then re-enter the control device.

[0169] Through the above control method, when the cleaning equipment is removed before completing the liquid replenishment process, the liquid supply system 110 can respond quickly, allowing the liquid to enter the return branch 116 and circulate in the loop formed by the liquid replenishment device 112 and the return branch 116. This effectively reduces or avoids liquid concentration in the second flow channel 1112 and effectively reduces the water volume at the end of the main flow channel 111. It also effectively reduces the water pressure at the end of the main flow channel 111, preventing situations where excessive water pressure at the end of the main flow channel 111 makes it difficult for the cleaning equipment to match the base station 100. This allows the cleaning equipment to better cooperate with the base station 100, effectively improving the user experience.

[0170] See also Figure 9 As shown, the control method also includes:

[0171] S103: When the first detection element 114 detects no water flow signal in the main flow path 111, the liquid replenishment device 112 is turned off.

[0172] For example, if the first detection element 114 does not detect a water flow signal after the liquid replenishment device 112 is turned on, then the liquid replenishment device 112 will be turned off.

[0173] After the replenishment device 112 has started operating and supplying liquid to the cleaning equipment, if the first detection element 114 does not detect a water flow signal in the main flow path 111, it indicates that there is no water source in the first flow channel 1111, and it is in a water outage state, or that the water supply tank of the base station 100 is empty. At this time, the system can promptly shut down the replenishment device 112 to avoid prolonged idling. This effectively reduces or avoids damage to the replenishment device 112 due to prolonged idling, effectively improving the protection of the replenishment device 112.

[0174] See also Figure 9 As shown, the control method also includes:

[0175] S104: When there is water in the liquid accumulation chamber 133 so that the third detection element 1331 and the fourth detection element 1332 are electrically connected and the liquid replenishment device 112 is working, the liquid replenishment device 112 is turned off.

[0176] Using the above control method, when water overflows from the liquid replenishment connector 134, causing the third detection element 1331 and the fourth detection element 1332 on the bottom wall of the liquid accumulation chamber 133 to become conductive, the system can quickly shut down the liquid replenishment device 112 to stop the liquid replenishment operation. This effectively prevents continuous water overflow at the liquid replenishment connector 134 from damaging the base station 100, thus effectively improving the protection of the base station 100.

[0177] S105: When there is water in the liquid accumulation chamber 133, the third detection element 1331 and the fourth detection element 1332 are electrically connected, and the brush plate stops self-cleaning during self-cleaning.

[0178] Through the above control method, when water overflows from the drainage component 140 and the third detection component 1331 and the fourth detection component 1332 on the bottom wall of the liquid accumulation chamber 133 are connected, the system can quickly stop the self-cleaning of the brush plate or roller brush, thereby effectively preventing the continuous overflow of water from damaging the base station 100 and effectively improving the protection of the base station 100.

[0179] See also Figure 9 As shown, the control method may also include:

[0180] S106: Once the second test piece matches the test piece on the cleaning equipment, start the liquid replenishment device 112.

[0181] When the second detection element matches the detection element on the cleaning equipment, indicating that the cleaning equipment is in place, the replenishment device 112 can be turned on so that the replenishment device 112 can deliver liquid to the cleaning equipment at the end of the main flow path 111.

[0182] See also Figure 9 As shown, the control method may also include:

[0183] S107: When the second detection element does not detect the detection element of the cleaning equipment, shut off the liquid replenishment device 112.

[0184] When the second detection device fails to detect the cleaning equipment, it indicates that the cleaning equipment is separated from the base station 100 and is not in place. At this time, the operation of the liquid replenishment device 112 can be stopped to prevent the liquid replenishment device 112 from starting when the cleaning equipment is not in place, which could damage the base station 100, the liquid supply system 110, and the liquid replenishment device 112. This helps to improve the protection of the base station 100, the liquid supply system 110, and the liquid replenishment device 112.

[0185] See also Figure 9 As shown, the control method may also include:

[0186] S108: When the charging electrode 120 engages with the electrode on the cleaning equipment, the liquid replenishment device 112 is activated;

[0187] S109: When the charging electrode 120 is disconnected from the electrode on the cleaning device, the liquid replenishment device 112 is turned off.

[0188] By determining the matching status between the charging electrode 120 and the electrode on the cleaning equipment, it can be determined whether the cleaning equipment is in place. Based on this matching status, the opening or closing of the liquid replenishment device 112 can be controlled. This effectively improves the reliability of the liquid replenishment device 112, preventing it from activating when the cleaning equipment is not in place, thus avoiding damage to the base station 100, the liquid supply system 110, and the liquid replenishment device 112. This enhances the protection of the base station 100, the liquid supply system 110, and the liquid replenishment device 112.

[0189] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
