Description

Technical Field

[0001] The utility model relates to the technical field of cleaning systems, and particularly relates to a cleaning system. Background Art

[0002] In recent years, with the improvement of people's living standards, home cleaning has gradually entered the era of automation and intelligence. The emerging cleaning equipment, such as floor washers, sweeping robots, etc., can liberate people from home cleaning work, effectively reduce the workload of people in home cleaning, and relieve the fatigue of people during home cleaning.

[0003] In related technologies, the cleaning equipment for floor washing usually includes a body, a floor brush, a clean water tank, a sewage tank, etc. Among them, the floor brush is arranged at the bottom of the body for cleaning the ground. The clean water tank and the sewage tank are both arranged on the body. Since a certain amount of water needs to be stored in the clean water tank and the sewage tank, the weight of the body is relatively large, and the center of gravity of the body is relatively high. After long-term use, the user's arms will be sore and exhausted.

[0004] In addition, when using this cleaning equipment, it is usually necessary to add water to the clean water tank. However, the height of the clean water tank is relatively low, and the user needs to bend down significantly to add water to the clean water tank, which is difficult for some elderly people or users with poor waists, with a large operation difficulty, bringing inconvenience to the user and resulting in a poor user experience. Summary of the Utility Model

[0005] An embodiment of the present application provides a cleaning system. The cleaning system can automatically add water to a first clean water tank on a floor brush assembly through a charging base. The bottom of the first clean water tank automatically admits water, with convenient water injection, high reliability and high water injection efficiency. The use difficulty of the cleaning system is low and the user experience is good.

[0006] A first aspect of the present application provides a cleaning system, including a cleaning device and a charging base. Among them, the cleaning device includes a floor brush assembly and a body, and the floor brush assembly is connected to the body. The floor brush assembly includes a housing, and a first clean water tank is clamped on the housing. An automatic water inlet valve is arranged at the bottom of the first clean water tank. The charging base is provided with a first charging part and a water injection channel for supplying water to the first clean water tank. The body is provided with a second charging part cooperating with the first charging part. The water injection channel is provided with an upward second protrusion on the surface of the charging base. When the cleaning device is docked with the charging base, the first charging part contacts the second charging part, and the second protrusion jacks up the automatic water inlet valve, so that the automatic water inlet valve is opened, enabling the first clean water tank to communicate with the water injection channel.

[0007] The cleaning system according to the embodiment of the present application is provided with a cleaning device and a charging stand. The cleaning device is used for cleaning work. By providing a first charging part on the charging stand and a second charging part on the body of the cleaning device, when the cleaning device is docked with the charging stand, the first charging part and the second charging part come into contact, so as to charge the cleaning device through the charging stand. By providing a first water tank on the floor brush assembly of the cleaning device, the first water tank is snapped onto the housing of the floor brush assembly, and a water injection channel for supplying water to the first water tank is provided on the charging stand. When the cleaning device is docked with the charging stand, the charging stand fills the first water tank with water, which can avoid the user bending down or squatting down significantly to add water to the first water tank, reduce the difficulty of adding water to the first water tank, and realize the automatic water supply operation conveniently during the charging process. For the user, there is no need to add extra actions, which can greatly improve the user experience. Among them, by providing an automatic water inlet valve at the bottom of the first water tank and providing a second protrusion on the surface of the charging stand that protrudes upward for the water injection channel, when the first water tank is placed downward on the housing, the second protrusion lifts the automatic water inlet valve, and the automatic water inlet valve is opened, and the first water tank is communicated with the water injection channel. When the cleaning device is simply placed on the charging stand for charging, the automatic water inlet at the bottom of the first water tank is realized incidentally, which is very labor-saving and convenient without redundant operations; by directly docking and inletting water from the bottom of the first water tank, there is no need to provide redundant water injection pipelines on the floor brush assembly, which greatly shortens the overall water injection path, reduces the resistance during the water injection process, enables the same water injection pump to pump water into the water tank faster, speeds up the automatic water inlet speed, saves the automatic water injection time, and the clear water automatically injected into the first water tank rises slowly from the bottom to full. The water injection process is stable, which can more accurately reflect the current water level situation, and thus more accurately feedback the current water inflow volume, so as to be used as part of the basis for the water injection pump to stop water injection; moreover, since the water injection port of the first water tank is at its bottom, far away from and lower than the charging part of the charging stand, it is difficult for the water near the first water tank to flow to the charging part above, further reducing the risk of electric shock.

[0008] In a possible implementation manner, a water storage tank is provided on the charging stand. When the floor brush assembly is docked with the charging stand, the first water tank is communicated with the water storage tank, and the water storage tank is at least used for filling the first water tank with water.

[0009] By providing a water storage tank on the charging stand, when the floor brush assembly is docked with the charging stand, the water storage tank fills the first water tank with water, which can avoid the user bending down or squatting down significantly to add water to the first water tank, reduce the difficulty of adding water to the first water tank, and can improve the user experience.

[0011] By providing a water injection channel in the charging base to connect to an external water source and arranging a control valve in the water injection channel to control the on / off of the water injection channel. When the floor brush assembly is docked with the charging base, the external water source injects water into the first water tank through the water injection channel, which can avoid the user bending down significantly or squatting down to add water to the first water tank, reducing the difficulty of adding water to the first water tank and improving the user experience.

[0012] In a possible implementation, a first water outlet is provided on the water storage tank. A first water inlet is provided on the first water tank, and the first water inlet is communicated with the first water tank.

Wherein, when the cleaning device is connected to the charging base, the first water outlet is communicated with the second water inlet, and the second water outlet is communicated with the first water inlet.

[0017] By providing a second water inlet and a second water outlet that are interconnected on the charging stand, the second water inlet and the second water inlet can be connected to both ends of the water injection channel. In this way, the first water outlet of the water storage tank is connected to the second water inlet of the charging stand. When the local brush assembly is docked with the charging stand, the first water inlet of the first clear water tank is connected to the second water outlet of the charging stand, thereby connecting the first water outlet and the first water inlet. This can improve the flexibility of the installation position of the water storage tank and also enhance the design flexibility of the installation position of the first clear water tank.

[0018] In a possible implementation, a first positioning portion is provided on the second water inlet, and a second positioning portion that cooperates with the first positioning portion is provided on the first water outlet. When the first positioning portion cooperates with the second positioning portion, the first water outlet is connected to the second water inlet.

[0020] In a possible implementation, a first protrusion is provided inside the first positioning portion, and an automatic water outlet valve is provided inside the second positioning portion. The automatic water outlet valve is used to seal or open the first water outlet. When the first positioning portion cooperates with the second positioning portion, the first protrusion opens the automatic water outlet valve, so that the first water outlet is connected to the second water inlet.

[0021] By providing an automatic water outlet valve, the first water outlet can be sealed or opened. For example, when the water storage tank is not installed on the charging stand, the first water outlet can be sealed through the automatic water outlet valve, which can prevent water leakage from the water storage tank. When the water storage tank is installed on the charging stand, the first protrusion can open the automatic water outlet valve to connect the first water outlet and the second water inlet.

[0022] In a possible implementation, a third positioning portion is provided on the first water inlet, and a fourth positioning portion that cooperates with the third positioning portion is provided on the second water outlet.

[0024] In a possible implementation, the second protrusion is disposed within the fourth positioning portion, and the automatic water inlet valve is disposed within the third positioning portion. The automatic water inlet valve is configured to seal or open the first water inlet. Wherein, when the third positioning portion cooperates with the fourth positioning portion, the second protrusion opens the automatic water inlet valve, so that the first water inlet communicates with the second water outlet.

[0025] By providing the automatic water inlet valve, the first water inlet can be sealed or opened. For example, when it is necessary to inject water into the first clean water tank through the first water inlet, the floor brush assembly can be disposed on the charging base and connected to the charging base, and the automatic water inlet valve can be opened by the second protrusion, so that the first water inlet communicates with the second water outlet. When it is not necessary to inject water into the first clean water tank through the first water inlet, for example, when using the cleaning device for cleaning work, the first water inlet can be sealed by the automatic water inlet valve to prevent the water in the first clean water tank from leaking out through the first water inlet.

[0026] In a possible implementation, a first control device is further included. Wherein, the first control device is electrically connected to the first water pump, and the first control device is configured to control the opening and closing of the first water pump.

[0027] By providing the first control device and controlling the opening and closing of the first water pump through the first control device, the process of injecting water from the water storage tank into the first clean water tank can be an automatic process, which is convenient and fast, can reduce the operation difficulty, and improve the user experience.

[0028] In a possible implementation, the charging base includes a first detection component. Wherein, the first detection component is configured to detect the water volume in the water storage tank. The first control device is electrically connected to the first detection component, and the first control device is configured to control the opening or closing of the first water pump according to the water volume in the water storage tank detected by the first detection component.

[0029] By providing the first detection component to detect the water volume in the water storage tank, the first water pump can be controlled whether to inject water into the first clean water tank according to the water volume in the water storage tank. For example, when the water volume in the water storage tank is small, the user can be reminded to add water to the water storage tank. When the water volume in the water storage tank is sufficient, the first clean water tank can be directly injected with water. This can improve the intelligence of the cleaning system, facilitate user use, and thus improve the user experience. In addition, by providing the first detection component, it is possible to prevent the first water pump from injecting water into the first clean water tank ineffectively when there is no water in the water storage tank.

[0030] In a possible implementation, the floor brush assembly includes a second detection component. The second detection component is configured to detect the water volume in the first clean water tank. The first control device is electrically connected to the second detection component, and the first control device is configured to control the opening or closing of the first water pump according to the water volume in the first clean water tank detected by the second detection component.

[0031] By providing the second detection component to detect the water volume in the first clean water tank, and by the first control device controlling the opening and closing of the first water pump according to the second detection component, it is possible to control whether the first water pump adds water to the first clean water tank according to the water volume in the first clean water tank, improving the automation of filling the first clean water tank, reducing the operation difficulty of the user, and enhancing the user experience. For example, when the water volume in the first clean water tank is small, the first water pump can be controlled to open and fill water into the first clean water tank. When the water volume in the first clean water tank is sufficient, the first water pump can be controlled to close and stop adding water to the first clean water tank. Throughout the process, filling the first clean water tank can be achieved without manual operation, and the problem of overflow of the first clean water tank caused by injecting excessive water into the first clean water tank can be prevented.

The third detection component is electrically connected to the first control device, and the first control device is configured to control the opening and closing of the first water pump according to the in-place status information of the water storage tank.

[0033] By providing the third detection component and setting it to detect the in-place status information of the water storage tank, and by the first control device controlling the opening and closing of the first water pump according to the in-place status information of the water storage tank, the safety of filling water from the water storage tank into the first clean water tank can be improved, problems such as water leakage can be prevented, and the user experience can be enhanced.

[0034] In a possible implementation, the in-place status information of the water storage tank includes an in-place status and an out-of-place status. When the in-place status information of the water storage tank is the in-place status, the first water outlet of the water storage tank is communicated with the second water inlet of the charging base.

[0035] By setting the in-place status information of the water storage tank to include the in-place status and the out-of-place status, and when the water storage tank is in the in-place status, the first water outlet is communicated with the second water inlet. In this way, the first control device can be used to control the first water pump to only open when the water storage tank is in the in-place status, so as to prevent water leakage between the first water outlet and the second water inlet when the water storage tank and the charging base are installed out of position, thereby improving the safety of the cleaning system and enhancing the user experience.

[0036] In a possible implementation, the third detection component includes a Hall sensor and a magnet element. Among them, the Hall sensor is disposed on one of the water storage tank or the charging base, and the magnet element is disposed on the other of the water storage tank or the charging base. Alternatively, the third detection component includes a micro switch, and the micro switch is disposed on the charging base. Alternatively, the third detection component includes a pressure sensor, and the pressure sensor is disposed on the charging base.

[0037] By configuring the third detection component to include a Hall sensor and a magnet element, a micro switch, or a pressure sensor, the structure of the third detection component can be simplified, and the setting is convenient, thereby reducing costs.

[0038] In a possible implementation, the charging base further includes a fourth detection component. Among them, the fourth detection component is used to detect the in-position status information of the floor brush component. The fourth detection component is electrically connected to the first control device, and the first control device is used to control the opening and closing of the first water pump according to the in-position status information of the floor brush component.

[0039] By providing a fourth detection component for detecting the in-position status of the floor brush component, it is further possible to detect whether the floor brush component is assembled in the correct position with the charging base, and the first control device controls the opening and closing of the first water pump according to the in-position status information of the floor brush component. This can improve the safety of injecting water from the water storage tank into the first clean water tank, prevent problems such as water leakage between the second water outlet and the first water inlet, and enhance the user experience.

[0040] In a possible implementation, the in-position status information of the floor brush component includes an in-position state and an out-of-position state. Among them, when the in-position status information of the floor brush component is in the in-position state, the first water inlet of the floor brush component is in communication with the second water outlet of the charging base.

[0041] By setting the in-position status information of the floor brush component to include an in-position state and an out-of-position state, and when the floor brush component is in the in-position state, the first water inlet is in communication with the second water outlet. In this way, the first control device can be used to control the first water pump to start only when the floor brush component is in the in-position state, so as to prevent water leakage between the second water outlet and the first water inlet when the floor brush component and the charging base are not properly installed, thereby improving the safety of the cleaning system and enhancing the user experience.

[0042] In a possible implementation, the fourth detection component includes a Hall sensor and a magnet element.

[0043] By setting the fourth detection component to include a Hall sensor and a magnet element, a microswitch or a pressure sensor, the structure of the fourth detection component can be simplified, and the setting is convenient, thereby reducing costs.

[0044] In a possible implementation, the charging base further includes a fifth detection component. Among them, the fifth detection component is used to detect the water pressure pumped into the first water pump and output a water full signal when it detects that the pumped water pressure reaches a preset pumped water pressure. The first control device is electrically connected to the fifth detection component, and the first control device is used to control the first water pump to close when receiving the water full signal.

[0045] By providing a fifth detection component on the charging base, the fifth detection component is used to detect the water pressure pumped into the first water pump and output a water full signal when the pumped water pressure reaches the preset pumped water pressure. By electrically connecting the fifth detection component to the first control device, when the first control device receives the water full signal output by the fifth detection component, the first control device controls the first water pump to close. In this way, it is possible to prevent excessive water from being injected into the first water tank and prevent the first water tank from overflowing.

[0046] In a possible implementation, the charging base includes a bearing portion and a supporting portion. Among them, the bearing portion includes a bearing surface. When the cleaning device is connected to the charging base, the floor brush assembly is located on the bearing surface. The supporting portion is located on the side of the bearing portion where the bearing surface is provided. One end of the supporting portion is connected to the bearing portion, and the other end extends in a direction away from the bearing surface. When the cleaning device is connected to the charging base, the body abuts against the supporting portion, and the first charging portion is located on the supporting portion.

[0047] By providing the charging base with a bearing portion to carry the floor brush assembly, it is ensured that the floor brush assembly can be stably connected to the charging base. By providing the supporting portion, the charging base can carry the floor brush assembly and support the body, improving the stable connection between the cleaning device and the charging base during charging and preventing the body from slipping off the charging base. Moreover, by providing the first charging portion on the supporting portion, the distance between the first charging portion and the second charging portion can be reduced, and thus it is more convenient to electrically connect the first charging portion and the second charging portion.

[0048] In a possible implementation, a first mating portion for mating with the support portion is provided on the water storage tank. When the water storage tank is connected to the charging base, the first mating portion is inserted and mated with the support portion.

[0049] By providing the first mating portion and making the first mating portion inserted and mated with the support portion when the water storage tank is connected to the charging base, the position of the water storage tank can be accurately positioned so that the water storage tank can be set at the correct installation position. That is to say, it is ensured that the first water outlet on the water storage tank can be connected in cooperation with the second water inlet on the charging base to prevent water leakage between the first water outlet and the second water inlet.

[0050] In a possible implementation, the first mating portion is a groove structure. Wherein, the opening of the groove structure faces the support portion. When the water storage tank is connected to the charging base, the support portion is located within the groove structure, and at least one surface of the support portion abuts against the groove structure.

[0051] By setting the first mating portion as a groove structure, the structure of the water storage tank can be simplified, thereby reducing the processing difficulty of the water storage tank and reducing the cost. And the groove structure has an enclosing and supporting effect, which can play a certain supporting and protecting role for the support portion.

[0052] In a possible implementation, a second mating portion is provided on the water storage tank, and a plug-in portion mating with the second mating portion is provided on the charging base. When the water storage tank is connected to the charging base, the second mating portion is inserted and mated with the plug-in portion.

[0053] By providing the second mating portion on the water storage tank and the plug-in portion on the charging base, the position of the water storage tank can be further restricted so that the water storage tank can be set at the correct installation position, ensuring that the first water outlet on the water storage tank can be connected in cooperation with the second water inlet on the charging base to prevent water leakage between the first water outlet and the second water inlet.

[0054] In a possible implementation, the plug-in portion is a strip structure, and the second mating portion is a groove structure matching the shape of the plug-in portion.

[0055] By setting the plug-in portion as a strip structure, the shape of the plug-in portion can be simplified, thereby reducing the processing difficulty of the plug-in portion and the carrying portion, and further reducing the cost. By setting the second mating portion as a groove structure, the structure of the water storage tank can be simplified, thereby reducing the processing difficulty of the water storage tank and reducing the cost.

[0056] In a possible implementation, the floor brush assembly includes a rotary brush. Wherein, in the advancing direction of the floor brush assembly, the rotary brush is located on one side of the housing, and the first water tank is located on the other side of the housing.

[0057] By arranging the floor brush assembly to include a rotary brush and setting the rotary brush and the first water tank on both sides of the housing along the advancing direction of the floor brush assembly, the rotary brush and the first water tank can be arranged oppositely. Since the space on the side of the housing opposite to the rotary brush is larger, the volume of the first water tank can be made larger, thereby reducing the frequency of filling water into the first water tank and improving the user experience.

[0058] In a possible implementation, in the advancing direction of the floor brush assembly, the rotary brush is located at the front side of the housing, and the first water tank is located at the rear side of the housing. Moreover, walking wheels are provided at both ends of the rear side of the housing, and the first water tank is located between the walking wheels at both ends.

[0059] By setting the rotary brush at the front side of the housing and the first water tank at the rear side of the housing, in the advancing direction of the floor brush assembly, the rotary brush first contacts the surface to be cleaned, which can ensure that the rotary brush fully cleans the surface to be cleaned. And there is enough space at the rear side of the housing to install the first water tank, which can ensure that the first water tank has enough volume and avoid frequent water addition. Moreover, by setting the first water tank between the walking wheels at both ends of the rear side of the housing, more pressure of the first water tank is borne by the walking wheels, which can reduce the frictional resistance when the floor brush assembly advances and avoid excessive frictional force between the rotary brush and the surface to be cleaned.

[0060] The second aspect of the present application provides a cleaning system, including a cleaning device and a charging stand. Wherein, the cleaning device includes a floor brush assembly and a body, and the floor brush assembly is connected to the body. The floor brush assembly includes a housing, and a first water tank is clamped on the housing. An automatic water inlet valve is provided at the bottom of the first water tank. A first charging part for the water storage tank and a water injection channel for supplying water to the first water tank are provided on the charging stand, and a second charging part for cooperating with the first charging part is provided on the body. When the cleaning device is docked with the charging stand, the first charging part contacts the second charging part, and the automatic water inlet valve is opened and the first water tank is communicated with the water injection channel.

[0061] The first clean water tank includes: a main body portion disposed near the bottom of the floor brush assembly; two expansion portions respectively protruding from both sides of the top of the main body portion, both of the two expansion portions communicating with the main body portion, and at least part of the top spaces of the two expansion portions being separated by a partition portion; wherein, an air inlet valve and an air outlet valve are provided on the two expansion portions, and the air inlet valve and the air outlet valve are provided on the same expansion portion or respectively on the two expansion portions; a communication channel extending from the main body portion into the two expansion portions, and the gases in the two expansion portions communicate with each other through the communication channel.

[0062] In the cleaning system according to the embodiment of the present application, by providing a cleaning device and a charging base, the cleaning work is carried out by using the cleaning device, and a first charging portion is provided on the charging base, and a second charging portion is provided on the body of the cleaning device. When the cleaning device is docked with the charging base, the first charging portion and the second charging portion are in contact, so as to charge the cleaning device through the charging base. By providing a first clean water tank on the floor brush assembly of the cleaning device, the first clean water tank is snapped onto the housing of the floor brush assembly, and a water injection channel for supplying water to the first clean water tank is provided on the charging base. When the cleaning device is docked with the charging base, the first clean water tank is filled with water through the charging base, which can avoid the user bending down or squatting significantly to add water to the first clean water tank, reduce the difficulty of adding water to the first clean water tank, and improve the user experience. Among them, by providing an automatic water inlet valve at the bottom of the first clean water tank, when the first clean water tank is placed downward on the housing, the automatic water inlet valve is opened, and the first clean water tank communicates with the water injection channel, so that automatic water inlet at the bottom of the first clean water tank can be realized.

[0063] The first clear water tank is provided with two expansion parts on both sides of the top of the main body part respectively. Both expansion parts are communicated with the main body part to increase the volume of the clear water tank. Moreover, the clear water tank can make full use of the accommodation space of the housing, and is convenient for positioning the clear water tank, which can improve the installation reliability of the clear water tank. Among them, limited by the accommodation space of the housing and the avoidance of the connection position of the fuselage, at least part of the top space of the two expansion parts is separated by a partition part, and this part of the space of the two expansion parts is not directly communicated. Since during the automatic water injection process of the first clear water tank, as the water level in the first clear water tank rises, the air in the two expansion parts slowly discharges. However, when the water level rises to the position of the expansion part, it will be found that only the expansion part provided with an exhaust valve can discharge air, and the air in the expansion part without an exhaust valve cannot be discharged smoothly, resulting in the problem that the first clear water tank cannot be filled during the automatic water injection process. Therefore, in this embodiment, the two expansion parts are communicated by setting a communication channel. When the water level in the first clear water tank gradually rises to the position of the expansion part, since the indirect air circulation space below the two expansion parts is blocked by water, the air in the expansion part without an exhaust valve can only flow into the expansion part provided with an exhaust valve through the communication channel, so that a common exhaust valve can be used for exhaust, enabling the air in both expansion parts to be quickly discharged as the water level rises until the expansion part is filled with water, improving the utilization rate of the clear water tank. Moreover, the setting of the communication channel also accelerates the air intake process of the clear water tank, facilitating the stable and rapid output of the clear water in the clear water tank. Especially during the process of draining water after the clear water tank is full of water. During this process, the air entering the expansion part provided with an air intake valve can quickly flow into the expansion part without an air intake valve through the communication channel, so that air can quickly enter the tops of both expansion parts, forming air pressure at the top of the expansion part, facilitating the stable decline of the water level in the clear water tank, being conducive to the accurate monitoring of the remaining water volume in the clear water tank, and avoiding the situation that the water in the expansion part without an air intake valve cannot be discharged at the beginning and needs to wait until the water in the other expansion part provided with an air intake valve is drained before being discharged, ensuring the stability during the water discharge process of the clear water tank.

[0064] By setting an air intake valve on one of the two expansion parts and an exhaust valve on this expansion part or the other expansion part, the air intake valve can allow external air to enter the clear water tank to ensure the water discharge flow rate of the clear water tank, and the exhaust valve can discharge the air in the clear water tank to the outside to ensure the water injection effect of the clear water tank. Moreover, by setting a communication channel extending from the main body part to the two expansion parts in the clear water tank, the air in the expansion part without an exhaust valve can be transported to the expansion part provided with an exhaust valve through the communication channel, so that the air in both expansion parts can be discharged through the exhaust valve, achieving the effect of filling the clear water tank completely, avoiding users from frequently adding water, and improving the use experience of the cleaning equipment.

[0065] In a possible implementation, both the intake valve and the exhaust valve are provided at the top of the side wall or the upper surface of the expansion part.

[0066] By arranging both the intake valve and the exhaust valve at the top of the side wall or the upper surface of the expansion part, both the intake valve and the exhaust valve are located at the highest position of the expansion part. So that the air in the expansion part can be completely discharged through the exhaust valve, and moreover, it can prevent the cleaning water in the expansion part from overflowing from the intake valve or the exhaust valve.

[0067] In a possible implementation, a water injection port is provided at one end of the clean water tank, and the intake valve and the exhaust valve are located at the end where the water injection port is located.

[0068] By arranging both the intake valve and the exhaust valve at the end of the clean water tank where the water injection port is located, when manually injecting water into the clean water tank, both the intake valve and the exhaust valve are located at the highest position of the first clean water tank. The air in the first clean water tank can be smoothly discharged through the exhaust valve. And moreover, it can prevent water from overflowing from the part where the intake valve is located, ensuring the reliability of use of the first clean water tank.

[0069] In a possible implementation, the inner wall of the side of the expansion part facing away from the main body part is the inner top wall of the expansion part, and the gap between the end of the communication channel and the inner top wall of the expansion part is less than a preset distance.

[0070] By making the gap between the end of the communication channel and the inner top wall of the expansion part less than the preset distance, the gap between the port of the communication channel and the inner top wall of the expansion part can allow the air in the expansion part to enter the communication channel, and the gap between the port of the communication channel and the inner top wall of the expansion part is small enough to allow the air at the top of the expansion part to completely enter the communication channel, avoiding the retention of air in the expansion part.

[0071] In a possible implementation, the communication channel is integrally formed on the inner wall of the clean water tank, or the communication channel is fixed in the clean water tank through a positioning part provided in the clean water tank.

[0072] The third aspect of the present application provides a cleaning system, including a cleaning device and a charging base. Wherein, the cleaning device includes a floor brush assembly and a body, and the floor brush assembly is connected to the body. The floor brush assembly includes a housing, and a first clean water tank is clamped on the housing, and an automatic water inlet valve is provided at the bottom of the first clean water tank. A first charging part for storing water and a water injection channel for supplying water to the first clean water tank are provided on the charging base, a second charging part for cooperating with the first charging part is provided on the body, when the cleaning device is docked with the charging base, the first charging part contacts the second charging part, and the automatic water inlet valve is opened and the first clean water tank is communicated with the water injection channel.

[0073] The first fresh water tank includes: a main body portion disposed near the bottom of the floor brush assembly; two expansion portions respectively protruding on both sides of the top of the main body portion, both of the two expansion portions communicating with the main body portion, and a partition portion being provided between the two expansion portions, at least part of the top space of the two expansion portions being separated by the partition portion; wherein, exhaust valves are provided on the top of the side walls or the upper surfaces of the two expansion portions.

[0074] In the cleaning system according to the embodiment of the present application, by providing a cleaning device and a charging base, using the cleaning device to perform cleaning work, and by providing a first charging portion on the charging base and a second charging portion on the body of the cleaning device, when the cleaning device is docked with the charging base, the first charging portion and the second charging portion are in contact to charge the cleaning device through the charging base. By providing a first fresh water tank on the floor brush assembly of the cleaning device, the first fresh water tank is snap-fitted on the housing of the floor brush assembly, and a water injection channel for supplying water to the first fresh water tank is provided on the charging base. When the cleaning device is docked with the charging base, the first fresh water tank is filled with water through the charging base, which can avoid the user bending down or squatting significantly to add water to the first fresh water tank, reduce the difficulty of adding water to the first fresh water tank, and improve the user experience. Among them, by providing an automatic water inlet valve at the bottom of the first fresh water tank, when the first fresh water tank is placed downward on the housing, the automatic water inlet valve is opened, and the first fresh water tank communicates with the water injection channel, so that automatic water inlet at the bottom of the first fresh water tank can be realized.

[0075] The first fresh water tank is provided with two expansion portions respectively on both sides of the top of the main body portion, and both of the two expansion portions communicate with the main body portion to increase the volume of the fresh water tank. Moreover, the fresh water tank can make full use of the accommodation space of the housing, and is convenient for positioning the fresh water tank, which can improve the installation reliability of the fresh water tank. Among them, limited by the accommodation space of the housing and the avoidance of the connection position of the body, at least part of the top space of the two expansion portions is separated by the partition portion, and this part of the space of the two expansion portions is not directly communicated. By providing exhaust valves on both of the two expansion portions, the exhaust valves can discharge the air in the fresh water tank to the outside, ensuring the water injection effect of the fresh water tank. Moreover, the air in the two expansion portions can be discharged through their respective exhaust valves to achieve the effect of filling the fresh water tank completely, avoiding the user adding water frequently, and improving the use experience of the cleaning device. And, by arranging the exhaust valves on the top of the side walls or the upper surfaces of the expansion portions, the exhaust valves are located at the highest positions of the expansion portions. So that the air in the expansion portions can be completely discharged through the exhaust valves.

[0076] In a possible implementation manner, at least one of the two expansion portions is provided with an air inlet valve.

[0077] By providing an air inlet valve in the expansion portion, the air inlet valve can allow external air to enter the fresh water tank to ensure the water outlet flow rate of the fresh water tank.

[0078] In a possible implementation, the expansion part includes a main expansion part and an extension part that are connected and communicate with each other. The main expansion parts of the two expansion parts are away from each other, and the extension parts of the two expansion parts are located on the side where the two main expansion parts are close to each other.

[0079] By providing a main expansion part and an extension part that are connected and communicate with each other to jointly form the expansion part, the main expansion parts of the two expansion parts are away from each other, and the extension parts of the two expansion parts are respectively located on the side where the corresponding main expansion parts are close to each other. The main expansion part avoids the position where the rotating connection part is located. The main expansion part has a relatively large volume and is the main structural part of the expansion part. The extension part corresponds to the position where the rotating connection part is located and needs to avoid the rotating connection part, and the extension part has a relatively small volume.

[0080] In a possible implementation, from the side of the main expansion part facing the roller brush to the other side of the main expansion part, the cross-sectional area of the main expansion part gradually decreases.

[0081] In a possible implementation, the side of the main expansion part facing the roller brush has an avoidance notch, and the avoidance notch communicates with the top wall of the expansion part.

[0082] By providing an avoidance notch on the main expansion part in the expansion part of the first clean water tank, setting the avoidance notch on the side of the main expansion part facing the roller brush, and making the avoidance notch communicate with the top wall of the expansion part, so as to avoid the corresponding structure in the accommodation space of the housing through the avoidance notch, and make the clean water tank match the accommodation space in the housing.

[0083] In a possible implementation, the main body part has an assembly notch, the assembly notch faces the roller brush, and the assembly notch is used to avoid the rotating connection part between the floor brush assembly and the fuselage. Among them, the assembly notch is located in the area surrounded by the two expansion parts.

[0084] By providing an assembly notch facing the roller brush on the main body part of the first clean water tank, so as to avoid the rotating connection part connected between the floor brush assembly and the fuselage through the assembly notch. The space between the two expansion parts is also used to avoid the rotating connection part, and compared with the assembly notch, the space between the two expansion parts can be larger, so as to be able to accommodate the larger upper part of the rotating connection part, make the assembly notch located in the area surrounded by the two expansion parts, and the top port of the assembly notch is exposed between the two expansion parts.

[0085] In a possible implementation, the clean water tank further includes a handle part, and the handle part is located between the extension parts of the two expansion parts;

[0086] The main body part is provided with a handle groove, and the handle groove is located below the handle part.

[0087] By arranging a handle part between the extension parts of the two enlarged parts, the handle part can be used as a partition part to separate the two enlarged parts. Moreover, the user can move the first clean water tank by holding the handle part, which is convenient for the installation, disassembly and movement of the first clean water tank. In addition, by arranging a handle groove on the main body part and setting the handle groove below the handle part, the handle groove can provide a holding space for the user, which conforms to ergonomics and can ensure the stability and reliability of the user's operation of the first clean water tank.

[0088] In a possible implementation manner, the handle part is provided with a movable positioning structure, and the positioning structure is used for clamping with the housing of the floor brush assembly.

[0118] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0119] In current society, more and more families begin to introduce cleaning equipment, such as a floor washer. The working mode of the floor washer generally works by washing and mopping. For this reason, it needs to be equipped with a clean water tank and a sewage tank, and uses the method of cleaning with running water. However, this brings the problem that users need to add water to the clean water tank regularly or frequently. At the same time, most current clean water tanks and sewage tanks are set on the body, so the body is very heavy, which brings a great burden to users.

[0120] Based on this, this case provides a solution of setting the clean water tank on the floor brush. The above solution can reduce the weight of the body and relieve the burden on users. However, this brings the problem that adding water to the above clean water tank brings a greater burden on users to replace the clean water, and users need to almost squat down to replace it.

[0121] For this reason, on this basis, this case also provides a way to supply water to the clean water tank on the floor brush, so that users do not need to replace the water frequently. In this way, the present application provides a solution that can both relieve the user's use burden and relieve the user's replacement burden

[0122] The cleaning system provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0123] Figure 1Schematic structural diagram of a cleaning system provided by an embodiment of the present application. Figure 2 Exploded structural diagram of a cleaning system provided by an embodiment of the present application.

[0124] An embodiment of the present application provides a cleaning system 100, as Figure 1 shown. The cleaning system 100 may include a cleaning device 10 and a charging base 20. Among them, the cleaning device 10 may include a floor brush assembly 12 and a body 11, and the floor brush assembly 12 is connected to the body 11. A first clean water tank 14 is provided on the floor brush assembly 12, and a water storage tank 30 is provided on the charging base 20. The water storage tank 30 is at least used to fill the first clean water tank 14 with water.

[0125] Among them, a handgrip 11a may be provided at the top of the body 11. When the user uses the cleaning device 10, the user can operate the cleaning device 10 to perform cleaning work through the handgrip 11a.

[0126] In the prior art, when the user replenishes clean water, it is usually necessary to frequently bend down and squat to remove and install the clean water tank, and run back and forth to refill the water, which is very troublesome and laborious. Moreover, frequently disassembling and assembling the clean water tank is likely to cause the assembly structure between the clean water tank and the floor brush assembly to become loose. Over time, there is often a risk that the clean water tank will fall off during scenarios such as the floor brush assembly bumping or lifting during the user's use process, causing the user to have to abort the current cleaning task to reinstall the clean water tank, which is not conducive to the continuous progress of the cleaning task and reduces the user experience. Through the application of the solution of this embodiment, the user's actions of bending down and squatting to remove and install the clean water tank for refilling can be greatly reduced, the risk of the assembly structure between the clean water tank and the floor brush assembly becoming loose can be reduced, and the problem that the clean water tank falls off the floor brush assembly during the cleaning process can be avoided, enabling the cleaning task to continue. Moreover, in the embodiments of the present application, automatic replenishment of clean water is achieved incidentally only in scenarios such as charging and self-cleaning, and the user does not need to perform additional operations, which is very easy and convenient and saves the user's time.

[0127] In the cleaning system 100 of the embodiments of the present application, by providing the cleaning device 10, the cleaning system 100 can perform cleaning work through the cleaning device 10, effectively reducing the workload of people in home cleaning. By providing the charging base 20, the cleaning device 10 can be charged through the charging base 20.

[0128] By using the cleaning device 10 equipped with a floor brush assembly 12 for cleaning operations, and by providing a body 11, users can control the direction of the floor brush assembly 12 through the body 11, which can reduce the degree of bending for users and thus enhance the user experience. By providing a first water tank 14 on the floor brush assembly 12 and a water storage tank 30 on the charging dock 20, and filling the first water tank 14 with water from the water storage tank 30, this can prevent users from having to bend down significantly or squat down to add water to the first water tank 14, reducing the difficulty of filling the first water tank 14 and enhancing the user experience.

[0129] As Figure 2 shown, the water storage tank 30 is provided with a first water outlet 31. The first water tank 14 is provided with a first water inlet 141. When the cleaning device 10 is placed on the charging dock 20 and the floor brush assembly 12 of the cleaning device 10 is docked with the charging dock 20, the first water inlet 141 of the first water tank 14 is in communication with the first water outlet 31 of the water storage tank 30.

[0130] By providing a first water inlet 141 on the first water tank 14, the first water tank 14 can be filled with water through this first water inlet 141. By providing a first water outlet 31 on the water storage tank 30 and connecting the first water outlet 31 and the first water inlet 141, the water storage tank 30 can fill the first water tank 14 with water through the first water outlet 31 and the first water inlet 141.

[0131] It should be noted that the first water outlet 31 and the first water inlet 141 can be connected through an external pipeline or through a pipeline on the charging dock 20. In the embodiments of the present application, no further limitation is imposed on the connection method between the first water outlet 31 and the first water inlet 141.

[0132] Exemplarily, a water injection channel can be provided in the charging dock 20. When the floor brush assembly 12 is provided on the charging dock 20, the first water outlet 31 of the water storage tank 30 and the first water inlet 141 of the first water tank 14 can be connected through the water injection channel.

[0133] In some embodiments, the charging dock 20 may not be provided with a water storage tank 30, but instead the charging dock 20 is directly connected to an external water source. When the cleaning device 10 is placed on the charging dock 20 and the floor brush assembly 12 is docked with the charging dock 20, the first water inlet 141 of the first water tank 14 is in communication with the external water source to directly fill the first water tank 14 with water from the external water source.

[0134] If the solution of this embodiment is not adopted, after the user continuously uses it multiple times, the water storage tank needs to be removed and carried back and forth to refill the water. However, the water storage tank is relatively heavy, which is not conducive to the handling of people with less strength, and the problem of adding clean water cannot be solved once and for all. Through the application of the solution of this embodiment, the problem of adding clean water can be solved once and for all. When the cleaning device is charging, there is always a stable external water source (tap water faucet) supply. As long as the external water supply is not cut off, manual water addition is not required all the time. The automatic water addition that solves the problem once and for all further liberates the user.

[0135] Taking the example that the charging base 20 is provided with a water injection channel, one end of the water injection channel is used to connect to an external water source, and the other end of the water injection channel is used for the floor brush assembly 12 to connect. And, a control valve can be provided in the water injection channel, and the control valve can control the on and off of the water injection channel.

[0136] When the floor brush assembly 12 is docked with the charging base 20 and water needs to be injected into the first water tank 14, the first water inlet 141 of the first water tank 14 is communicated with the other end of the water injection channel, and the control valve controls the water injection channel to open, and the external water source injects water into the first water tank 14 through the water injection channel. When the floor brush assembly 12 is separated from the charging base 20 or when the first water tank 14 is full of water, the control valve controls the water injection channel to disconnect, cutting off the water injection channel and the external water source.

[0137] The following will take the example that a water storage tank 30 is provided on the charging base 20 and water is injected into the first water tank 14 through the water storage tank 30 for description. Figure 3 It is a schematic structural diagram of the charging base 20 of a cleaning system 100 provided by an embodiment of the present application.

[0138] As Figure 3 shown, the charging base 20 is provided with a second water inlet 23 and a second water outlet 24 that are connected to each other. The second water inlet 23 and the second water inlet 24 can be connected to both ends of the water injection channel. In this way, the first water outlet 31 of the water storage tank 30 is communicated with the second water inlet 23 of the charging base 20. When the cleaning device 10 is docked with the charging base 20, the first water inlet 141 of the first water tank 14 is communicated with the second water outlet 24 of the charging base 20, thereby connecting the first water outlet 31 of the water storage tank 30 and the first water inlet 141 of the first water tank 14. In this way, the flexibility of the installation position of the water storage tank 30 can be improved, and the design flexibility of the installation position of the first water tank 14 can be improved.

[0139] It should be noted that when the cleaning device 10 is connected to the charging base 20, it means that the cleaning device 10 is set on the charging base 20 and is stably connected to the charging base 20. Or, when the cleaning device 10 is set at the correct position on the charging base 20, when the cleaning device 10 is connected to the charging base 20, the first water inlet 141 and the second water inlet 23 are sealed and communicated with each other.

[0140] In a possible implementation, the charging base 20 includes a bearing part 21. Among them, the bearing part 21 includes a bearing surface 211. When the cleaning device 10 is connected to the charging base 20, the floor brush assembly 12 is located on the bearing surface 211.

[0141] Exemplarily, the bearing part 21 can be a cuboid box-like structure, and components such as the circuit board of the charging base 20 can be arranged inside the bearing part 21. Among them, the bearing surface 211 is located at the top of the bearing part 21, and the shape of the bearing surface 211 matches the shape of the bottom surface of the floor brush assembly 12, so that the floor brush assembly 12 can be stably connected to the bearing part 21.

[0142] Of course, in other embodiments, the bearing part 21 can also be set to other shapes, for example, a round cake-like structure, a polygonal columnar structure, etc. In the embodiments of the present application, the specific structure of the bearing part 21 is not further limited.

[0143] By setting the charging base 20 to include the bearing part 21 to bear the floor brush assembly 12, it is ensured that the floor brush assembly 12 can be stably connected to the charging base 20.

[0144] Continue to refer to Figure 3 As shown, the charging base 20 can also include a support part 22. Among them, the support part 22 is located on the side of the bearing part 21 where the bearing surface 211 is provided, and the support part 22 is arranged at an angle with the bearing part 21. One end of the support part 22 is connected to the bearing part 21, and the other end extends in a direction away from the bearing surface 211. When the cleaning device 10 is connected to the charging base 20, the body 11 abuts against the support part 22.

[0145] Exemplarily, the angle between the support part 22 and the bearing part 21 can be between 80° and 100°, for example, it can be 90°. In this way, the support part 22 and the bearing part 21 can be close to perpendicular, which can improve the support effect of the support part 22 and can also improve the aesthetics of the charging base 20.

[0146] By setting the support part 22, the charging base 20 can bear the floor brush assembly 12 and can also support the body 11, improving the stable connection between the cleaning device 10 and the charging base 20 during charging and preventing the body 11 from slipping off the charging base 20.

[0147] Exemplarily, both the second water inlet 23 and the second water outlet 24 can be arranged on the bearing surface 211. Among them, a connecting pipeline (not shown in the figure) is provided between the second water inlet 23 and the second water outlet 24, and the connecting pipeline is arranged inside the bearing part 21. One end of the connecting pipeline is connected to the second water outlet 24, and the other end is connected to the second water inlet 23 to communicate the second water inlet 23 and the second water outlet 24.

[0148] Among them, the connecting pipeline can be a flexible pipe, a rigid pipe or other connecting pipes. In the embodiments of the present application, the specific structure of the connecting pipeline will not be further described.

[0149] By arranging the second water inlet 23 on the bearing surface 211, the distance between the first water outlet 31 and the second water inlet 23 can be shortened, thereby facilitating the connection between the first water outlet 31 and the second water inlet 23. By arranging the second water outlet 24 on the bearing surface 211, the distance between the first water inlet 141 and the second water outlet 24 can be shortened, thereby facilitating the connection between the first water inlet 141 and the second water outlet 24. By arranging a connecting pipeline between the second water outlet 24 and the second water inlet 23 to communicate between the second water outlet 24 and the second water inlet 23, and by arranging the connecting pipeline inside the bearing part 21, the connecting pipeline can be invisibly arranged in the bearing part 21, which can improve the aesthetics of the charging base 20.

[0150] In a possible implementation manner, as Figure 4 shown, the first water inlet 141 is located on the bottom surface of the floor brush assembly 12. Among them, when the floor brush assembly 12 is located on the bearing surface 211, the first water inlet 141 is cooperatively connected with the second water outlet 24 and is mutually communicated. By arranging the first water inlet 141 on the bottom surface of the floor brush assembly 12, the distance between the first water inlet 141 and the second water outlet 24 can be reduced, thereby facilitating the connection between the first water inlet 141 and the second water outlet 24.

[0151] In a possible implementation manner, as Figure 5 shown, a first water pump 42 can be arranged on the charging base 20. Among them, the first water pump 42 is arranged between the first water inlet 141 and the first water outlet 31, and the first water pump 42 is used to pump the water in the water storage tank 30 into the first clean water tank 14 when it is turned on.

[0152] By arranging the first water pump 42 on the charging base 20 and arranging the first water pump 42 between the first water inlet 141 and the first water outlet 31, the first water pump 42 can provide power for the water flowing out of the first water outlet 31, so as to inject the water flowing out of the first water outlet 31 into the first clean water tank 14 and improve the water injection efficiency.

[0153] Exemplarily, the first water pump 42 can be arranged between the second water inlet 23 and the second water outlet 24.

[0154] It should be noted that when the first water pump 42 is turned on, the water storage tank 30 can inject water into the first clean water tank 14. When the first water pump 42 is turned off, the water storage tank 30 does not inject water into the first clean water tank 14, or the water storage tank 30 stops injecting water into the first clean water tank 14.

[0155] In a possible implementation, the cleaning device 10 further includes a first control device 41. The first control device 41 is electrically connected to the first water pump 42, and the first control device 41 is configured to control the opening and closing of the first water pump 42.

[0156] By providing the first control device 41 and controlling the opening and closing of the first water pump 42 through the first control device 41, the process of filling the first clean water tank 14 with water from the water storage tank 30 can be an automatic process. Compared with manual control, control through the first control device 41 is more accurate, convenient and fast, can reduce the operation difficulty, and improve the user experience.

[0157] Exemplarily, the first control device 41 can be provided on the charging base 20 or on the cleaning device 10. In the embodiments of the present application, the installation position of the first control device 41 is not further limited.

[0158] In a possible implementation, the charging base 20 is further provided with a first detection component 43. The first detection component 43 is configured to detect the water volume in the water storage tank 30. The first control device 41 is electrically connected to the first detection component 43, and the first control device 41 is configured to control the opening or closing of the first water pump 42 according to the water volume in the water storage tank 30 detected by the first detection component 43.

[0159] Of course, in other embodiments, the first detection component 43 can also be provided on the water storage tank 30. In the embodiments of the present application, the installation position of the first detection component 43 is not further limited.

[0160] Exemplarily, when the water volume in the water storage tank 30 is less than a first preset threshold, the first control device 41 controls the first water pump 42 to close, and the water storage tank 30 does not fill the first clean water tank 14. When the water volume in the water storage tank 30 is greater than the first preset threshold, the first control device 41 controls the first water pump 42 to open, and the water storage tank 30 fills the first clean water tank 14.

[0161] It should be noted that in the embodiments of the present application, the specific value of the first preset threshold is not further limited, and can be specifically determined according to the capacities of the water storage tank 30 and the first clean water tank 14.

[0162] By setting the first detection component 43 to detect the water volume in the water storage tank 30, the first water pump 42 can be controlled to inject water into the first clean water tank 14 according to the water volume in the water storage tank 30. For example, when the water volume in the water storage tank 30 is small, the user can be reminded to add water to the water storage tank 30. When the water volume in the water storage tank 30 is sufficient, water can be directly injected into the first clean water tank 14. This can improve the intelligence of the cleaning system 100, facilitate the user to use, and thus improve the user experience. In addition, by setting the first detection component 43, it can prevent the first water pump 42 from injecting water into the first clean water tank 14 in vain when there is no water in the water storage tank 30.

[0163] Exemplarily, a reminder device can also be provided on the charging base 20 or the water storage tank 30. When the water volume in the water storage tank 30 is less than a preset threshold, the reminder device can send a reminder message to remind the user to add water to the water storage tank 30.

[0164] It should be noted that the first detection component 43 includes but is not limited to a pressure sensor, an infrared sensor, a gravity sensor, etc. In the embodiments of the present application, the specific structure of the first detection component 43 will not be further described.

[0165] In a possible implementation, the floor brush assembly 12 may include a second detection component 44. The second detection component 44 is used to detect the water volume in the first clean water tank 14. The first control device 41 is electrically connected to the second detection component 44, and the first control device 41 is used to control the first water pump 42 to be turned on or off according to the water volume in the first clean water tank 14 detected by the second detection component 44.

[0166] Of course, in other embodiments, the second detection component 44 can also be provided on the first clean water tank 14. In the embodiments of the present application, the installation position of the second detection component 44 will not be further limited.

[0167] Exemplarily, when the water volume in the water storage tank 30 is less than a second preset threshold, the first control device 41 controls the first water pump 42 to be turned on, and the water storage tank 30 injects water into the first clean water tank 14. When the water volume in the first clean water tank 14 is greater than the second preset threshold, the first control device 41 controls the first water pump 42 to be turned off, so that the water storage tank 30 stops injecting water into the first clean water tank 14. This prevents the problem of water overflow in the first clean water tank 14 caused by injecting too much water into the first clean water tank 14.

[0168] It should be noted that the second preset threshold can be the maximum water volume that the first clean water tank 14 can hold. Of course, it can also be other values. In the embodiments of the present application, the specific value of the second preset threshold will not be further limited, and can be specifically determined according to the capacity of the first clean water tank 14.

[0169] By setting the second detection component 44 to detect the water volume in the first clean water tank 14, and controlling the opening and closing of the first water pump 42 by the first control device 41 according to the second detection component 44, it is possible to control whether the first water pump 42 adds water to the first clean water tank 14 according to the water volume in the first clean water tank 14, improving the automation of filling the first clean water tank 14, reducing the operation difficulty of the user, and enhancing the user experience. For example, when the water volume in the first clean water tank 14 is small, the first water pump 42 can be controlled to start and fill water into the first clean water tank 14. When the water volume in the first clean water tank 14 is sufficient, the first water pump 42 can be controlled to close and stop filling water into the first clean water tank 14. In the whole process, manual operation is not required to realize filling the first clean water tank 14.

[0170] The following introduces the water injection logic between the water storage tank 30 and the first clean water tank 14.

[0171] Exemplarily, when the cleaning device 10 is set on the charging base 20, the cleaning device 10 starts self-cleaning. When the water volume in the first clean water tank 14 detected by the second detection component 44 is greater than the water volume required for self-cleaning, the self-cleaning program proceeds normally. After the drying program ends, when the second detection component 44 detects that the water volume in the first clean water tank 14 is insufficient, the first control device 41 can control the first water pump 42 to start, so that the water storage tank 30 injects water into the first clean water tank 14. When the second detection component 44 detects that the first clean water tank 14 is full of water, the first control device 41 controls the first water pump 42 to close, ending the water injection program.

[0172] Exemplarily, when the cleaning device 10 is set on the charging base 20, the cleaning device 10 can start the self-cleaning program. When the water volume in the first clean water tank 14 detected by the second detection component 44 is less than the water volume required for self-cleaning and greater than 0, the self-cleaning program can be started normally. When the water volume in the first clean water tank 14 is used up, the self-cleaning program stops and the water injection function is started. The injected water volume is greater than or equal to the self-cleaning water volume, and then the self-cleaning is resumed. After the drying program ends, the water injection function is started again. When the water is full, the program ends. Among them, the water volume in the first clean water tank 14 is detected in real time by the second detection component 44, and the opening and closing of the water injection function are realized by the first control device 41 controlling the first water pump 42. This is not elaborated in the embodiments of the present application.

[0173] Exemplarily, when the cleaning device 10 is set on the charging base 20, the self-cleaning program is started. When the water volume in the first clean water tank 14 detected by the second detection component 44 is equal to 0, the self-cleaning does not start, and then the water injection function is started. When the injected water volume is greater than or equal to the self-cleaning water volume, the self-cleaning program is resumed. After the drying program ends, the water injection function is started again. After the water tank is full, the water injection program ends. Among them, the water volume in the first clean water tank 14 is detected in real time by the second detection component 44, and the opening and closing of the water injection function are controlled by the first control device 41 to control the first water pump 42. This will not be elaborated in the embodiments of the present application.

[0174] It should be noted that the water injection logic between the water storage tank 30 and the first clean water tank 14 can also be in other forms. In the embodiments of the present application, the water injection logic between the water storage tank 30 and the first clean water tank 14 will not be further described.

[0175] In a possible implementation manner, as Figure 6 shown, a first positioning portion 231 is provided on the second water inlet 23, and a second positioning portion 311 that cooperates with the first positioning portion 231 is provided on the first water outlet 31. When the first positioning portion 231 cooperates with the second positioning portion 311, the first water outlet 31 is communicated with the second water inlet 23.

[0176] Exemplarily, the first positioning portion 231 can be a first annular wall extending outward around the outer edge of the second water inlet 23, and the second positioning portion 311 can be a second annular wall extending outward around the outer edge of the first water outlet 31. Among them, the inner diameter of the second annular wall is greater than the inner diameter of the first annular wall. When the water storage tank 30 is connected to the charging base 20, the first annular wall is inserted into the second annular wall and is hermetically connected to the second annular wall, so that the first water outlet 31 and the second water inlet 23 are oppositely arranged and hermetically connected.

[0177] Or, the inner diameter of the first annular wall is greater than the inner diameter of the second annular wall. When the water storage tank 30 is connected to the charging base 20, the second annular wall is inserted into the first annular wall and is hermetically connected to the first annular wall, so that the first water outlet 31 and the second water inlet 23 are oppositely arranged and hermetically connected. In the embodiments of the present application, the inner diameters of the first annular wall and the second annular wall are not further limited. When the first annular wall and the second annular wall are of a polygonal structure, the inner diameters of the first annular wall and the second annular wall refer to the inner dimensions of the annular walls.

[0178] By providing the first positioning portion 231 at the second water inlet 23 and the second positioning portion 311 that cooperates with the first positioning portion 231 at the first water outlet 31, it is convenient to accurately communicate the first water outlet 31 and the second water inlet 23, and it is possible to prevent water leakage caused by misaligned connection between the first water outlet 31 and the second water inlet 23.

[0179] Exemplarily, a first protrusion 232 is provided in the first positioning portion 231, and an automatic water outlet valve 32 is provided in the second positioning portion 311. The automatic water outlet valve 32 is used to seal or open the first water outlet 31, and it is a valve body assembly. Wherein, when the first positioning portion 231 cooperates with the second positioning portion 311, the first protrusion 232 opens the automatic water outlet valve 32, so that the first water outlet 31 communicates with the second water inlet 23.

[0180] Exemplarily, the automatic water outlet valve 32 may include a first housing portion 321, a first blocking portion 322, and a first elastic portion 323. The first blocking portion 322 and the first elastic portion 323 are both disposed in the first housing portion 321, and the first housing portion 321 communicates with the water storage tank 30. The first elastic portion 323 is compressively disposed between the top wall of the first housing portion 321 and the first blocking portion 322. One end of the first elastic portion 323 abuts against the top wall of the first housing portion 321, and the other end abuts against the first blocking portion 322.

[0181] Among them, as Figure 7 shown, one end of the first blocking portion 322 facing the first water outlet 31 is located in the first water outlet 31, and when the water storage tank 30 is not connected to the charging base 20, the first blocking portion 322 can be hermetically connected to the first water outlet 31 under the pressure of the first elastic portion 323. When the water storage tank 30 and the charging base 20 are connected, the first positioning portion 231 and the second positioning portion 311 are cooperatively connected. That is to say, the first annular wall of the first positioning portion 231 is inserted into the second annular wall of the second positioning portion 311, and the first protrusion 232 in the first positioning portion 231 abuts against one end of the first blocking portion 322 facing the first water outlet 31. As the water storage tank 30 and the charging base 20 approach each other, the first protrusion 232 drives the first blocking portion 322 to move away from the charging base 20, and the sealing relationship between the first blocking portion 322 and the first water outlet 31 is broken, so that the first water outlet 31 communicates with the water storage tank 30. At this time, the first water outlet 31 is opened, and water can be injected into the second water inlet 23 through the first water outlet 31.

[0182] By providing the automatic water outlet valve 32, the first water outlet 31 can be sealed or opened. For example, when the water storage tank 30 is not installed on the charging base 20, the first water outlet 31 can be sealed by the automatic water outlet valve 32, which can prevent the water storage tank 30 from leaking. When the water storage tank 30 is installed on the charging base 20, the first protrusion 232 can open the automatic water outlet valve 32 so that the first water outlet 31 communicates with the second water inlet 23.

[0183] It should be noted that the automatic water outlet valve 32 may also have other structures. In the embodiments of the present application, the specific structure of the automatic water outlet valve 32 is not further limited.

[0184] Similarly, as Figure 8 shown, in order to ensure quick positioning and connection between the first water inlet 141 and the second water outlet 24, a third positioning portion 142 can be provided on the first water inlet 141, and a fourth positioning portion 241 that cooperates with the third positioning portion 142 can be provided on the second water outlet 24. Among them, when the third positioning portion 142 cooperates with the fourth positioning portion 241, the first water inlet 141 communicates with the second water outlet 24.

[0185] Exemplarily, the third positioning portion 142 can be a third annular wall extending outward around the outer edge of the first water inlet 141, and the fourth positioning portion 241 can be a fourth annular wall extending outward around the outer edge of the second water outlet 24. Among them, the inner diameter of the third annular wall is greater than the inner diameter of the fourth annular wall. When the local brush assembly 12 is connected to the charging base 20, the fourth annular wall is inserted into the third annular wall and is hermetically connected to the third annular wall, so that the first water inlet 141 and the second water outlet 24 are oppositely arranged and hermetically connected.

[0186] Alternatively, the inner diameter of the fourth annular wall is greater than the inner diameter of the third annular wall. When the local brush assembly 12 is connected to the charging base 20, the third annular wall is inserted into the fourth annular wall and is hermetically connected to the fourth annular wall, so that the first water inlet 141 and the second water outlet 24 are oppositely arranged and hermetically connected. In the embodiments of the present application, the inner diameters of the third annular wall and the fourth annular wall are not further limited. When the third annular wall and the fourth annular wall are of a polygonal structure, the inner diameters of the third annular wall and the fourth annular wall refer to the dimensions inside the annular wall.

[0187] By providing the third positioning portion 142 on the first water inlet 141 and the fourth positioning portion 241 that cooperates with the third positioning portion 142 on the second water outlet 24, it is convenient to accurately connect the second water outlet 24 and the first water inlet 141, and it is possible to prevent water leakage caused by misaligned connection between the second water outlet 24 and the first water inlet 141.

[0188] Exemplarily, a second protrusion 242 is provided inside the fourth positioning portion 241, and the second protrusion 242 protrudes upward on the bearing surface 211 of the charging base 20. An automatic water inlet valve 143 is provided inside the third positioning portion 142. The automatic water inlet valve 143 is used to seal or open the first water inlet 141, and it is a kind of valve body assembly. Among them, when the third positioning portion 142 cooperates with the fourth positioning portion 241, the second protrusion 242 opens the automatic water inlet valve 143, so that the first water inlet 141 communicates with the second water outlet 24.

[0189] In this embodiment, by providing an automatic water inlet valve at the bottom of the first clean water tank and providing a second protrusion on the surface of the charging base that protrudes upward for the water injection channel, when the first clean water tank is placed downward on the housing, the second protrusion pushes up the automatic water inlet valve, and the automatic water inlet valve is opened, so that the first clean water tank is communicated with the water injection channel. When the cleaning device is simply placed on the charging base for charging, automatic water inlet at the bottom of the first clean water tank is achieved incidentally, which is very labor-saving and convenient without any extra operations. By directly docking for water inlet from the bottom of the first clean water tank, no extra water injection pipelines need to be provided on the floor brush assembly, which greatly shortens the overall water injection path, reduces the resistance during the water injection process, enables the same water injection pump to pump water into the clean water tank faster, speeds up the automatic water inlet speed, saves the automatic water injection time, and the clean water automatically injected into the first clean water tank rises slowly from the bottom until it is full. The water injection process is stable, which can more accurately reflect the current water level, and thus more accurately feedback the current water inflow volume, so as to be used as part of the basis for the water injection pump to stop water injection. Moreover, since the water injection port of the first clean water tank is at its bottom, far from and lower than the charging part of the charging base, it is difficult for the water near the first clean water tank to flow to the charging part above, further reducing the risk of electric shock. If the solution of this embodiment is not adopted, the water injection port of the first clean water tank may be provided on the side. Due to the limitation of the housing of the floor brush assembly, it cannot be directly docked to the water outlet of the charging base, and water injection pipelines need to be added to the floor brush assembly, which will increase the overall water injection path, is not conducive to the rapid injection of clean water, and due to the increase of the floor brush pipelines, its internal structure becomes more complex, and corresponding fixing parts and holes will also be increased, resulting in a further increase in cost.

[0190] Exemplarily, the automatic water inlet valve 143 may include a second housing part 1431, a second blocking part 1432, and a second elastic part 1433. The second blocking part 1432 and the second elastic part 1433 are both arranged in the second housing part 1431, and the second housing part 1431 is communicated with the first clean water tank 14. The second elastic part 1433 is compressively arranged between the top wall of the second housing part 1431 and the second blocking part 1432. One end of the second elastic part 1433 abuts against the top wall of the second housing part 1431, and the other end abuts against the second blocking part 1432.

[0191] Among them, as Figure 9As shown, one end of the second plugging part 1432 facing the first water inlet 141 is located inside the first water inlet 141, and when the floor brush assembly 12 is not connected to the charging base 20, the second plugging part 1432 can be hermetically connected to the first water inlet 141 under the pressure of the second elastic part 1433. When the first water tank 14 is connected to the charging base 20, the third positioning part 142 and the fourth positioning part 241 are cooperatively connected. That is to say, the fourth annular wall of the fourth positioning part 241 is inserted into the third annular wall of the third positioning part 142, and the second protrusion 242 inside the fourth positioning part 241 abuts against one end of the second plugging part 1432 facing the first water inlet 141. As the first water tank 14 and the charging base 20 approach each other, the second protrusion 242 drives the second plugging part 1432 to move away from the charging base 20, breaking the sealing relationship between the second plugging part 1432 and the first water inlet 141. Thus, the first water inlet 141 is communicated with the first water tank 14, and at this time, the first water inlet 141 is opened, and water can be injected into the first water inlet 141 through the second water outlet 24.

[0192] By providing the automatic water inlet valve 143, the first water inlet 141 can be sealed or opened. For example, when it is necessary to inject water into the first water tank 14 through the first water inlet 141, the floor brush assembly 12 can be arranged on the charging base 20 and connected to the charging base 20, and the automatic water inlet valve 143 can be opened through the second protrusion 242 to communicate the first water inlet 141 and the second water outlet 24. When it is not necessary to inject water into the first water tank 14 through the first water inlet 141, for example, when using the cleaning device 10 for cleaning work, the first water inlet 141 can be sealed through the automatic water inlet valve 143 to prevent the water in the first water tank 14 from leaking out through the first water inlet 141.

[0193] It should be noted that the structure of the automatic water inlet valve 143 in the embodiments of the present application can be the same as or different from the structure of the automatic water outlet valve 32. In the embodiments of the present application, the specific structure of the automatic water inlet valve 143 is not further limited.

[0194] In addition, since the automatic water inlet valve 143 is arranged at the bottom of the first water tank 14 and cooperates with the second protrusion 242 protruding on the bearing surface 211 of the charging base 20, when the first water tank 14 is placed downward on the floor brush assembly 12, the second protrusion 242 pushes up the automatic water inlet valve 143 upward, thereby communicating the water injection channels in the first water tank 14 and the charging base 20, and the water storage tank 30 can automatically inject water into the first clean water tank 14.

[0195] With such a setting, the automatic water inlet valve 143 of the first clean water tank 14 is provided at its bottom. Only by moving the first clean water tank 14 downward along the direction of gravity can the automatic water inlet valve 143 be brought into abutment with the second protrusion 242 on the charging base 20. The first clean water tank 14 and the second protrusion 242 are in an up-and-down docking manner, which is convenient for docking and has a high docking accuracy. Moreover, compared with the side water inlet mode of the clean water tank, by setting the first clean water tank 14 to have a bottom water inlet mode, during the process of installing and disassembling the first clean water tank 14, it is not necessary to translate the first clean water tank 14 too much, and it is not easy to accidentally touch some structures and components provided on the side wall of the first clean water tank 14. For example, it is not easy to accidentally touch the detection component provided on the first clean water tank 14. In addition, the first water inlet 141 of the first clean water tank 14 is directly communicated with the inside of the first clean water tank 14. The water injection path of the first clean water tank 14 is short, the water injection efficiency is high, and the required water injection pressure can be reduced, thereby reducing the power consumption of the first water pump 42.

[0196] In a possible implementation manner, as Figure 10 shown, the water storage tank 30 is detachably connected to the charging base 20. By setting the water storage tank 30 to be detachably connected to the charging base 20, the water storage tank 30 can be detached for cleaning, water injection, etc., improving the flexibility of the application scenario of the water storage tank 30 and enhancing the user experience.

[0197] In some embodiments, the water storage tank 30 can be supported and positioned by the support portion 22 of the charging base 20. Among them, the water storage tank 30 is provided with a first mating portion 33 for cooperating with the support portion 22. When the water storage tank 30 and the charging base 20 are connected, the first mating portion 33 is in plug-in fit with the support portion 22.

[0198] Exemplarily, the first mating portion 33 is a groove structure, and the opening of the groove structure faces the support portion 22; when the water storage tank 30 and the charging base 20 are connected, the support portion 22 is located in the groove structure, and at least one side of the support portion 22 abuts against the groove structure.

[0199] Exemplarily, the first mating portion 33 is located in the middle of the water storage tank 30. Among them, the first mating portion 33 can be a groove structure provided around three sides of the support portion 22, which can provide support for the support portion 22, thereby enhancing the stability of the support portion 22. Among them, the groove structure can penetrate the water storage tank 30 or not penetrate the water storage tank 30.

[0200] It can be understood that the first mating portion 33 can also be a groove structure located on one side of the water storage tank 30, and the groove structure can be provided around two sides of the support portion 22. Of course, the first mating portion 33 can also be other structures.

[0201] It should be noted that the shape of the first engaging portion 33 is related to the arrangement position and outer shape of the supporting portion 22. In the embodiments of the present application, the outer shape of the supporting portion 22 and the shape of the first engaging portion 33 are not further limited.

[0202] By providing the first engaging portion 33 and making the first engaging portion 33 engage with the supporting portion 22 in a plugging manner when the water storage tank 30 is connected to the charging base 20, the installation position of the water storage tank 30 can be accurately positioned, so that the water storage tank 30 can be set at the correct installation position. That is to say, it is ensured that the first water outlet 31 on the water storage tank 30 can be engaged and connected with the second water inlet 23 on the charging base 20 to prevent water leakage between the first water outlet 31 and the second water inlet 23.

[0203] In some embodiments, as Figure 11 shown, the water storage tank 30 may further be provided with a second engaging portion 34, and the charging base 20 is provided with a plugging portion 221 that engages with the second engaging portion 34. When the water storage tank 30 is connected to the charging base 20, the second engaging portion 34 engages with the plugging portion 221 in a plugging manner.

[0204] By providing the second engaging portion 34 on the water storage tank 30 and providing the plugging portion 221 on the charging base 20, the position of the water storage tank 30 can be further restricted, so that the water storage tank 30 can be set at the correct installation position, ensuring that the first water outlet 31 on the water storage tank 30 can be engaged and connected with the second water inlet 23 on the charging base 20 to prevent water leakage between the first water outlet 31 and the second water inlet 23.

[0205] Exemplarily, the plugging portion 221 may be a strip-shaped structure. Among them, at least one surface of the strip-shaped structure is an inclined surface, and in the direction from the top to the bottom of the plugging portion 221, the inclined surface gradually inclines outward, so that the cross-sectional area of the top of the strip-shaped structure is smaller than the cross-sectional area of the bottom, which is convenient for plugging with the second engaging portion 34. It should be noted that the top of the strip-shaped structure refers to the end away from the bearing portion 21 of the charging base 20.

[0206] Correspondingly, the second engaging portion 34 is a groove structure that matches the shape of the plugging portion 221. In the embodiments of the present application, the specific shapes of the plugging portion 221 and the second engaging portion 34 are not further limited.

[0207] Continuing to refer to Figure 12 shown, the water storage tank 30 may further be provided with a handle 35, a water filling port 36, etc. By providing the handle 35 on the water storage tank 30, it is convenient to remove the water storage tank 30 for cleaning, water filling, etc. By providing the water filling port 36 on the water storage tank 30, it is convenient to fill water into the water storage tank 30.

[0208] Of course, in some embodiments, the handle 35 or the water injection port 36 may not be provided, and instead, the water storage tank 30 may be directly connected to an external water pipe. When water injection is required, the valve of the external water pipe is directly opened to inject water into the water storage tank 30.

[0209] In a possible implementation, as Figure 13 shown, the charging base 20 further includes a third detection component 45. The third detection component 45 is used to detect the in-position status information of the water storage tank 30. The in-position status information of the water storage tank 30 includes an in-position status and an out-of-position status. The third detection component 45 is electrically connected to the first control device 41, and the first control device 41 is used to control the opening and closing of the first water pump 42 according to the in-position status information of the water storage tank 30.

[0210] Exemplarily, when the in-position status information of the water storage tank 30 is the in-position status, the first water outlet 31 of the water storage tank 30 is communicated with the second water inlet 23 of the charging base 20. That is to say, there is a connection between the water storage tank 30 and the charging base 20.

[0211] By providing the third detection component 45 and setting the third detection component 45 to detect the in-position status information of the water storage tank 30, and controlling the opening and closing of the first water pump 42 by the first control device 41 according to the in-position status information of the water storage tank 30, the safety of injecting water from the water storage tank 30 into the first clean water tank 14 can be improved, problems such as water leakage can be prevented, and the user experience can be enhanced.

[0212] Exemplarily, the third detection component 45 may include a Hall sensor and a magnet element. The Hall sensor is provided on one of the water storage tank 30 or the charging base 20, and the magnet element is provided on the other of the water storage tank 30 or the charging base 20.

[0213] In some other embodiments, the third detection component 45 may include a micro switch, and the micro switch is provided on the charging base 20. This can facilitate the connection between the micro switch and the first control device 41.

[0214] In some other embodiments, the third detection component 45 may further include a pressure sensor, and the pressure sensor is provided on the charging base 20. This can facilitate the connection between the pressure sensor and the first control device 41.

[0215] By providing the third detection component 45 to include a Hall sensor and a magnet element, a micro switch or a pressure sensor, the structure of the third detection component 45 can be simplified, and the setting is convenient, thereby reducing costs. It should be noted that the third detection component 45 may be provided on the water storage tank or on the charging base. In the embodiments of the present application, the setting position of the third detection component 45 is not further limited.

[0216] In a possible implementation, as Figure 13 shown, the charging base 20 further includes a fourth detection component 46. Among them, the fourth detection component 46 is used to detect the in-position status information of the floor brush component 12. The in-position status information of the floor brush component 12 includes the in-position status and the out-of-position status. Among them, the fourth detection component 46 is electrically connected to the first control device 41, and the first control device 41 is used to control the opening and closing of the first water pump 42 according to the in-position status information of the floor brush component 12.

[0217] Exemplarily, when the in-position status information of the floor brush component 12 is the in-position status, the first water inlet 141 of the floor brush component 12 is communicated with the second water outlet 24 of the charging base 20. That is, the floor brush component 12 and the charging base 20 are connected.

[0218] By setting the fourth detection component 46 for detecting the in-position status of the floor brush component 12, and then detecting whether the floor brush component 12 is assembled with the charging base 20 at the correct position, and controlling the opening and closing of the first water pump 42 by the first control device 41 according to the in-position status information of the floor brush component 12. The safety of injecting water from the water storage tank 30 into the first clean water tank 14 can be improved, problems such as water leakage between the second water outlet 24 and the first water inlet 141 can be prevented, and the user experience can be enhanced.

[0219] Exemplarily, the fourth detection component 46 includes a Hall sensor and a magnet element. Among them, the Hall sensor is disposed on one of the floor brush component 12 or the charging base 20, and the magnet element is disposed on the other of the floor brush component 12 or the charging base 20.

[0220] In some other embodiments, the fourth detection component 46 includes a micro switch, and the micro switch is disposed on the charging base 20. This can facilitate the connection between the micro switch and the first control device 41.

[0221] In some other embodiments, the fourth detection component 46 includes a pressure sensor, and the pressure sensor is disposed on the charging base 20. This can facilitate the connection between the pressure sensor and the first control device 41.

[0222] By setting the fourth detection component 46 to include a Hall sensor and a magnet element, a micro switch or a pressure sensor, the structure of the fourth detection component 46 can be simplified, and the setting is convenient, thereby reducing the cost.

[0223] It should be noted that the fourth detection component 46 can be disposed on the floor brush component or on the charging base. In the embodiments of the present application, the setting position of the fourth detection component 46 is not further limited.

[0224] Continue to refer to Figure 13, in some embodiments, a fifth detection component 47 may further be provided in the cleaning system 100. The fifth detection component 47 is used to detect the water inlet pressure of the first water pump 42. And when the fifth detection component 47 detects that the water inlet pressure of the first water pump 42 reaches a preset water inlet pressure, the fifth detection component 47 outputs a water full signal. The fifth detection component 47 may also be electrically connected to the first control device 41. When the first control device 41 receives the water full signal output by the fifth detection component 47, the first control device 41 controls the first water pump 42 to close.

[0225] When the fifth detection component 47 detects that the water inlet pressure of the first water pump 42 reaches the preset water inlet pressure, it indicates that the first clean water tank 14 is already full of water. At this time, the fifth detection component 47 outputs a water full signal to the first control device 41, and the first control device 41 controls the first water pump 42 to close when receiving the water full signal. Such a setting can prevent excessive water from being injected into the first clean water tank 14 and prevent the problem of water overflow in the first clean water tank 14, so as to improve the reliability of the charging base 20 injecting water into the first clean water tank 14.

[0226] Exemplarily, the preset water inlet pressure may be a third preset threshold value, and the third preset threshold value is, for example, the rated pressure of the first water pump 42. Of course, the third preset threshold value may also be less than the rated pressure of the first water pump 42. In addition, the fifth detection component 47 may be provided on the charging base 20, or the fifth detection component 47 may also be provided on the floor brush assembly 12. The embodiments of the present application do not make specific limitations in this regard. In a possible implementation manner, as Figure 14 shown, a first charging portion 48 is provided on the charging base 20, and a second charging portion 49 is provided on the body 11. When the cleaning device 10 is connected to the charging base 20, the first charging portion 48 is electrically connected to the second charging portion 49. The charging base 20 charges the cleaning device 10 through the first charging portion 48 and the second charging portion 49.

[0227] By providing the first charging portion 48 on the charging base 20 and the second charging portion 49 on the body 11, the charging base 20 can charge the body 11 through the first charging portion 48 and the second charging portion 49, so that the cleaning device 10 can perform cleaning work.

[0228] In the embodiments of the present application, the first charging portion 48 may be provided on the support portion 22. By providing the first charging portion 48 on the support portion 22, the distance between the first charging portion 48 and the second charging portion 49 can be reduced, and thus the first charging portion 48 and the second charging portion 49 can be more conveniently electrically connected.

[0229] Of course, in other embodiments, the first charging part 48 can also be arranged on the water storage tank 30. For example, when the water storage tank 30 is fixedly connected to the charging base 20 and the support part 22 and the water storage tank 30 are of an integral structure, the first charging part 48 can be arranged on the water storage tank 30. Alternatively, a connecting line can also be arranged on the water storage tank 30. One end of the connecting line is electrically connected to the first charging part 48, and when the water storage tank 30 is connected to the charging base 20, the other end of the connecting line is electrically connected to the charging base 20, so that the first charging part 48 can be used to charge the cleaning device.

[0230] In the embodiments of the present application, the setting position of the first charging part 48 is not further limited. In addition, the specific structures of the first charging part 48 and the second charging part 49 are not further limited, as long as they can be charged.

[0231] In a possible implementation manner, as Figure 14 shown, the first charging part 48 is electrically connected to the first control device 41. The first control device 41 is used to control the opening and closing of the first charging part 48 according to the in-position state information of the floor brush assembly 12. Exemplarily, when the in-position state information of the floor brush assembly 12 is the in-position state, the first control device 41 controls the first charging part 48 to be turned on.

[0232] By electrically connecting the first charging part 48 and the first control device 41 and controlling the opening or closing of the first charging part 48 according to the in-position state information of the floor brush assembly 12, the safety performance of the cleaning system 100 can be improved, so as to prevent abnormal phenomena such as sparks and poor contact between the first charging part 48 and the second charging part 49 when there is no stable connection between the floor brush assembly 12 and the charging base 20. When the in-position state information of the floor brush assembly 12 is the in-position state, by controlling the first charging part 48 to be turned on through the first control device 41, the charging safety between the charging base 20 and the cleaning device 10 can be improved, and abnormal phenomena such as poor contact and discharge between the first charging part 48 and the second charging part 49 can be prevented, resulting in damage to the charging base 20 or the body 11.

[0233] The structure of the floor brush assembly 12 will be introduced below with reference to the drawings.

[0234] As Figure 15 shown, the floor brush assembly 12 can include a housing 121 and a roller brush 13. A receiving space 125 is provided on the housing 121, and the first water tank 14 is located in the receiving space 125. In the forward direction of the floor brush assembly 12, the roller brush 13 is located on one side of the housing 121, and the first water tank 14 is located on the other side of the housing 121. The forward direction refers to the forward direction when the cleaning device is working.

[0235] Among them, in the forward direction of the floor brush assembly 12, the rotary brush 13 can be located on the front side of the housing 121, while the first water tank 14 can be located on the rear side of the housing 121. With such a setting, when performing cleaning work, the user holds the body 11 by hand to control the forward direction of the floor brush assembly 12. The rotary brush 13 first contacts the surface to be cleaned, which can ensure the smooth movement of the floor brush assembly 12 and can fully clean the surface to be cleaned. Moreover, there is sufficient space behind the rotary brush 13 to install the first water tank 14, which can ensure that the first water tank 14 has a sufficient volume, avoid frequent water addition, and improve the user experience.

[0236] In addition, traveling wheels 15 can be provided on the rear side of the housing 121. The traveling wheels 15 can be located at both ends of the rear side of the housing 121 to roll on the surface to be cleaned through the traveling wheels 15, reduce the friction between the floor brush assembly 12 and the surface to be cleaned, make the floor brush assembly 12 move easily and flexibly, and reduce the operation difficulty for the user.

[0237] At this time, the first water tank 14 installed on the rear side of the housing 121 can be located between the traveling wheels 15 at both ends of the housing 121. With such a setting, the gravity of the first water tank 14 will be more transmitted to the traveling wheels 15 to share more pressure through the traveling wheels 15, avoiding excessive influence of the first water tank 14 on the rotary brush 13. Since the traveling wheels 15 are in rolling contact with the surface to be cleaned, the influence of the pressure of the first water tank 14 on it is small, which can reduce the frictional resistance when the floor brush assembly 12 moves forward, improve the endurance of the floor brush assembly 12. And it can avoid excessive friction between the rotary brush 13 and the surface to be cleaned, so as not to affect the service life of the rotary brush 13 and prevent damage to the surface to be cleaned.

[0238] Continue to refer to Figure 15 , the housing 121 includes a bottom wall 122 and side walls 124. An accommodation space 125 is formed between the bottom wall 122 and a part of the side walls 124. Among them, an opening 123 can be provided on the bottom wall 122. The first water inlet 141 is provided on the first water tank 14, and at least part of the structure of the first water inlet 141 is located at the opening 123.

[0239] By setting the housing 121 to include a bottom wall 122 and side walls 124 to accommodate the components of the floor brush assembly 12 and protect the components of the floor brush assembly 12. By providing an opening 123 on the bottom wall 122 and setting at least part of the first water inlet 141 at the opening 123, the first water inlet 141 can extend beyond the bottom wall 122 of the housing 121 to communicate with the first water outlet 31 or with the second water outlet 24 on the charging base 20.

[0240] Further, a water spray port 126 is provided on the inner wall of the accommodation space 125. When the first clean water tank 14 is assembled in the accommodation space 125, the water spray port 126 communicates with the first clean water tank 14. By providing the water spray port 126 on the inner wall of the accommodation space 125, when the first clean water tank 14 is assembled in the accommodation space 125, the water spray port 126 communicates with the first clean water tank 14, so that the first clean water tank 14 can spray water to the roller brush 13 in the floor brush assembly 12, improving the cleaning effect of the floor brush assembly 12.

[0241] Correspondingly, as Figure 16 shown, a connection hole 144 that cooperates with the water spray port 126 is provided on the first clean water tank 14. When the first clean water tank 14 is installed in the accommodation space 125, the connection hole 144 on the first clean water tank 14 communicates with the water spray port 126 and is hermetically connected. Among them, in the embodiment of the present application, the specific shapes of the water spray port 126 and the connection hole 144 are not further limited.

[0242] In a possible implementation manner, the first clean water tank 14 is detachably connected to the housing 121. By setting the first clean water tank 14 to be detachably connected to the housing 121, the first clean water tank 14 can be detached from the housing 121 for cleaning, which can prevent problems such as bacterial growth, improve safety, and enhance the user experience.

[0243] In a possible implementation manner, the first clean water tank 14 is located on one side of the housing 121 in the first direction, and the first direction is perpendicular to the advancing direction of the floor brush assembly 12.

[0244] By setting the first clean water tank 14 to be located on one side of the housing 121 in the first direction, and the first direction is perpendicular to the advancing direction of the floor brush assembly 12. Among them, the first direction can be the thickness direction of the housing 121 or the axial direction of the roller brush 13. When the first direction is the thickness direction of the housing 121, the first clean water tank 14 can be located at the top or bottom of the housing 121, which can further increase the volume of the first clean water tank 14, reduce the frequency of filling water into the first clean water tank 14, and enhance the user experience.

[0245] When the first direction is the axial direction of the roller brush 13, the first clean water tank 14 is arranged on one side of the roller brush 13 in the axial direction of the floor brush assembly 12. Since the body 11 of the cleaning device 10 can rotate backward relative to the floor brush assembly 12 in the advancing direction of the floor brush assembly 12, when the body 11 is placed on the ground, that is, when the body 11 lies flat, manual water injection or disassembly operations can also be performed on the first clean water tank 14 arranged on one side of the axial direction of the roller brush 13, which is convenient for users to use.

[0246] In a possible implementation manner, as Figure 17As shown, the cleaning device 10 may further include a second clean water tank 51, and the second clean water tank 51 is arranged on the body 11.

[0247] By providing the second clean water tank 51 and arranging the second clean water tank 51 on the body 11, the cleaning device 10 of the cleaning system 100 can include two clean water tanks, and a part of the clean water tank is located on the floor brush assembly 12, which can reduce the center of gravity height of the cleaning device 10, thereby reducing the burden on the user. In addition, by using the water storage tank 30 to fill the first clean water tank 14, the difficulty of filling the first clean water tank 14 by the user can be reduced, and the user experience can be improved.

[0248] In a possible implementation, the water storage tank 30 may be communicated with both the first clean water tank 14 and the second clean water tank 51, and the water storage tank 30 is used to fill the first clean water tank 14 and the second clean water tank 51.

[0249] By arranging the water storage tank 30 to fill both the first clean water tank 14 and the second clean water tank 51, the difficulty of filling the first clean water tank 14 and the second clean water tank 51 can be reduced, the burden on the user can be reduced, and the user experience can be improved.

[0250] In a possible implementation, the water storage tank 30 includes a third water outlet 37, and the second clean water tank 51 includes a third water inlet 511. The third water outlet 37 is communicated with the third water inlet 511. Exemplarily, the water storage tank 30 and the second clean water tank 51 may be connected through an external pipe. Of course, they may also be directly connected through the third water inlet 511 and the third water outlet 37. In the embodiments of the present application, the connection manner between the water storage tank 30 and the second clean water tank 51 is not further limited.

[0251] In addition, in some embodiments, the second clean water tank 51 may not be connected to the water storage tank 30, that is, the second clean water tank 51 can be filled with water manually. In the embodiments of the present application, the connection relationship between the water storage tank 30 and the second clean water tank 51 is not further limited.

[0252] By providing the third water outlet 37 on the water storage tank 30 and the third water inlet 511 on the second clean water tank 51, it is convenient to connect the water storage tank 30 and the second clean water tank 51 to realize filling the second clean water tank 51 with water from the water storage tank 30.

[0253] In a possible implementation, as Figure 18 shown, a second water pump 52 is provided on the charging base 20. Of course, it may also be arranged on the body 11. Among them, the second water pump 52 is arranged between the third water inlet 511 and the third water outlet 37, and the second water pump 52 is used to pump the water in the water storage tank 30 into the second clean water tank 51 when it is turned on.

[0254] By arranging a second water pump 52 on the charging base 20 and setting the second water pump 52 between the third water inlet 511 and the third water outlet 37, the second water pump 52 can provide power for the water flowing out of the third water outlet 37, so as to inject the water flowing out of the third water outlet 37 into the second clean water tank 51.

[0255] In a possible implementation, a second control device 53 is provided on the charging base 20. Of course, it can also be arranged on the body 11. The second control device 53 is electrically connected to the second water pump 52, and the second control device 53 is used to control the opening and closing of the second water pump 52.

[0256] By arranging the second control device 53 and controlling the opening and closing of the second water pump 52 through the second control device 53, the process of injecting water from the water storage tank 30 into the second clean water tank 51 can be an automatic process, which is convenient and fast, can reduce the operation difficulty, and improve the user experience.

[0257] In some embodiments, the first control device 41 and the second control device 53 can be arranged in a general control device. In the embodiments of the present application, the specific structures of the first control device 41 and the second control device 53 are not further limited.

[0258] It should be noted that, in some embodiments, a detection device 54 (not shown in the figure) for detecting the water volume in the second clean water tank 51 can also be arranged. The detection device 54 is similar to the function of the second detection component 44. The second control device 53 can control the opening and closing of the second water pump 52 according to the water volume in the second clean water tank 51 detected by the detection device 54, so as to improve the automation degree of injecting water into the second clean water tank 51 and improve the user experience.

[0259] It should be noted that the cleaning device can be a cleaning device with a cleaning function such as a floor washer. In the embodiments of the present application, the specific structure of the cleaning device is not further described.

[0260] The following will detail the clean water tank of the cleaning device 10, specifically the first clean water tank 14 arranged on the floor brush assembly 12.

[0261] Figure 19 It is a structural diagram of a first clean water tank from a perspective provided by the embodiments of the present application. Figure 20 For Figure 19 The sectional view of the first clean water tank in along the line A-A. Figure 21 For Figure 19 The sectional view of the first clean water tank in along the line B-B.

[0262] Refer to Figure 19As shown, the first clean water tank 14 on the floor brush assembly 12 may include an upper box body 145 and a lower box body 146. The upper box body 145 and the lower box body 146 jointly enclose a water storage space of the first clean water tank 14. Assembling the upper box body 145 and the lower box body 146 into the first clean water tank 14 facilitates the installation of components inside the first clean water tank 14. For example, it facilitates the installation of the aforementioned automatic water inlet valve 143 inside the first clean water tank 14.

[0263] Moreover, the first clean water tank 14 may include a main body portion 147 and two expansion portions 148. The main body portion 147 is disposed near the bottom of the floor brush assembly 12. The two expansion portions 148 both protrude on the top of the main body portion 147, and the two expansion portions 148 are respectively located on both sides of the top of the main body portion 147. Among them, the bottom of the main body portion 147 of the first clean water tank 14 may be supported on the bottom wall 122 of the housing 121, and the first water inlet 141 of the first clean water tank 14 may be disposed at the bottom of the main body portion 147 (see Figure 15 as shown).

[0264] Referring to Figure 20 as shown, in the first clean water tank 14, the two expansion portions 148 located in the upper part are both communicated with the main body portion 147 located in the lower part. The main body portion 147 may occupy most of the space of the first clean water tank 14, and the main body portion 147 may provide a relatively large water storage space. Each expansion portion 148 occupies a relatively small space of the first clean water tank 14, and the two expansion portions 148 as a whole may occupy a certain space to provide a certain water storage space.

[0265] Combined with Figure 20 and Figure 21 as shown, a partition portion is further provided in the upper part of the first clean water tank 14. The partition portion is located between the two expansion portions 148. Along the height direction of the first clean water tank 14, the partition portion at least occupies at least part of the space in the upper part of the first clean water tank 14, and the partition portion extends downward from the top of the first clean water tank 14. That is to say, at least part of the top space of the two expansion portions 148 is separated by the partition portion.

[0266] For example, the top space of the two expansion portions 148 is separated by the partition portion, while the bottom space of the two expansion portions 148 is directly communicated. Or, the two expansion portions 148 are completely separated by the partition portion, and the two expansion portions 148 are not directly communicated, but rely on the main body portion 147 below them to be communicated.

[0267] By adding two expansion parts 148 above the main body part 147, the two expansion parts 148 protrude from the top of the main body part 147. In this way, compared with the water tank with a flat top, the top of the first water tank 14 in this embodiment has a raised shape, which can achieve an expansion effect, increase the volume of the first water tank 14, and more cleaning water can be stored in the first water tank 14. The cleaning water stored in the first water tank 14 can be used for a longer time, which can avoid frequent water injection by users and improve the user experience. Moreover, the first water tank 14 can make full use of the accommodation space 125 of the housing 121, and the matching degree between the first water tank 14 and the accommodation space 125 is higher. The two expansion parts 148 can be used to position the first water tank 14 to improve the stability and reliability of the installation of the first water tank 14.

[0268] Among them, limited by the structure of the floor brush assembly 12, the accommodation space 125 on the housing 121 is limited. The two expansion parts 148 mainly occupy the two side spaces at the top of the main body part 147. Limited by the partition part, the adjacent sides of the two expansion parts 148 cannot be continuously extended completely, so that at least part of the top space of the two expansion parts 148 is separated by the partition part.

[0269] Since there is a rotating connection part 16 connected between the floor brush assembly 12 and the fuselage 11, the rotating connection part 16 occupies part of the space of the floor brush assembly 12, and the rotating connection part 16 needs to avoid the floor brush and be connected to the rear side of the housing 121 (see Figure 15 ), therefore, the first water tank 14 needs to avoid the rotating connection part 16. In this regard, referring to Figure 19 or Figure 21 as shown, the main body part 147 of the first water tank 14 can have an assembly notch 1472, the assembly notch 1472 faces the side where the roller brush 13 is located, and the assembly notch 1472 can be located at the middle part in the length direction of the main body part 147. The assembly notch 1472 of the main body part 147 corresponds to the rotating connection part 16, and the rotating connection part 16 can be located in the assembly notch 1472 to avoid the rotating connection part 16 through the assembly notch 1472.

[0270] Moreover, since the rotating connection part 16 extends upward to be connected to the fuselage 11, the rotating connection part 16 also occupies the upper space of the first water tank 14. For this reason, the two expansion parts 148 at the upper part of the first water tank 14 mainly occupy the two side spaces, and the space between the two expansion parts 148 is used to avoid the rotating connection part 16.

[0271] Among them, the cross-sectional area of the lower part of the rotating connection part 16 can be relatively small, and the assembly notch 1472 on the main body part 147 of the first clean water tank 14 can be relatively small. While the cross-sectional area of the lower part of the rotating connection part 16 can be relatively large, and the space between the two expansion parts 148 of the first clean water tank 14 can be relatively large to be able to accommodate the upper part of the rotating connection part 16. At this time, the assembly notch 1472 of the main body part 147 is located within the area surrounded by the two expansion parts 148, and the top port of the assembly notch 1472 is exposed between the two expansion parts 148.

[0272] The top of the first clean water tank 14 needs to completely avoid the upper part of the rotating connection part 16. Since the upper part of the rotating connection part 16 occupies a relatively large space, only a narrow contour can be reserved at the position of the rotating connection part 16 on the top of the first clean water tank 14, or the top of the first clean water tank 14 needs to be completely partitioned at the position of the rotating connection part 16. When a narrow contour is reserved at the position of the rotating connection part 16 on the top of the first clean water tank 14, this part is mainly occupied by the wall thickness of the first clean water tank 14 to ensure the structural strength and reliability of the first clean water tank 14. Therefore, the partition part of the top of the first clean water tank 14 can correspond to the position of the rotating connection part 16, and the two expansion parts 148 of the first clean water tank 14 are not directly connected at this position.

[0273] Refer to Figure 19 As shown, the expansion part 148 of the first clean water tank 14 can include a main expansion part 1481 and an extension part 1482. The main expansion part 1481 and the extension part 1482 are interconnected and jointly enclose the expansion part 148. The main expansion parts 1481 of the two expansion parts 148 are far away from each other. For example, the far ends of the two expansion parts 148 can be flush with the two ends of the main body part 147. The extension parts 1482 of the two expansion parts 148 are respectively located on the side where the two main expansion parts 1481 are close to each other, that is to say, the extension parts 1482 of the two expansion parts 148 are close to each other. The partition part can be located between the extension parts 1482 of the two expansion parts 148, and the partition part partitions the extension parts 1482 of the two expansion parts 148 to separate the two expansion parts 148.

[0274] Among them, the main expansion part 1481 of the expansion part 148 is located on both sides of the top of the main body part 147, and the main expansion part 1481 avoids the position where the rotation connection part 16 is located. The main expansion part 1481 can be arranged to match the main body part 147. The main expansion part 1481 has a relatively large volume and is the main structure of the expansion part 148. The extension part 1482 of the expansion part 148 is arranged corresponding to the position where the rotation connection part 16 is located. Since the rotation connection part 16 needs to be avoided, the volume of the extension part 1482 is relatively small. The extension part 1482 can extend out from the side of the main expansion part 1481 facing away from the roller brush 13. The side walls of the opposite sides of the two main expansion parts 1481 and the side walls of the two extension parts 1482 facing the roller brush 13 together enclose an avoidance space, and this avoidance space is used to avoid the upper part of the rotation connection part 16.

[0275] Exemplarily, when the rear side of the floor brush assembly 12 is designed as an arc-shaped curved surface structure, correspondingly, in the first water tank 14 located at the rear side of the floor brush assembly 12, the top surface of the expansion part 148 located at the upper part of the first water tank 14 can also be designed as an arc-shaped curved surface structure. Among them, in the expansion part 148 of the first water tank 14, from the side of the main expansion part 1481 facing the roller brush 13 to the other side of the main expansion part 1481, the top surface of the main expansion part 1481 gradually approaches the main body part 147, and the cross-sectional area of the main expansion part 1481 gradually decreases.

[0276] In addition, when a strengthening part 127 is provided on the inner top wall of the accommodation space 125 of the housing 121 (see Figure 15 as shown), correspondingly, an avoidance notch 14811 can be provided on the expansion part 148 of the first water tank 14, and the avoidance notch 14811 corresponds to the strengthening part 127. When the first water tank 14 is installed on the floor brush assembly 12, the strengthening part 127 in the accommodation space 125 of the housing 121 can be located in the avoidance notch 14811 on the expansion part 148 of the first water tank 14. Among them, the avoidance notch 14811 can be located on the main expansion part 1481 of the expansion part 148, and the avoidance notch 14811 is located on the side of the main expansion part 1481 facing the roller brush 13, and the avoidance notch 14811 communicates with the top wall of the expansion part 148 to avoid the strengthening part 127 in the accommodation space 125 of the housing 121.

[0277] Figure 22 For Figure 19 the structural diagram of the first water tank from another perspective in Figure 22As shown, the partition part at the top of the first clean water tank 14 can be used as the handle part 149. In other words, the handle part 149 can be located between the two expansion parts 148 of the first clean water tank 14. Specifically, the handle part 149 can be located between the extension parts 1482 of the two expansion parts 148. On the basis of separating the two expansion parts 148, the user can also hold the handle part 149 to move the first clean water tank 14. In this way, it is convenient for the installation, disassembly and movement of the first clean water tank 14, which can reduce the operation difficulty of the first clean water tank 14 and improve the user experience.

[0278] Moreover, a handle groove 1471 can be provided on the main body part 147 of the first clean water tank 14. The handle groove 1471 is provided corresponding to the handle part 149 and can be located below the handle part 149. For example, the handle groove 1471 can be opened on the side of the main body part 147 facing away from the roller brush 13, and the handle groove 1471 is located at the middle part in the length direction of the main body part 147. The handle groove 1471 is used to provide a holding space for the user, and the user's hand can reach into the handle groove 1471 to hold the handle part 149. Such a setting is more ergonomic, can increase the contact area between the human hand and the handle part 149, and ensure the stability and reliability of the user's operation of the first clean water tank 14.

[0279] Figure 23 For Figure 22 the partial cross-sectional view of the first clean water tank along the C-C line in Figure 23 As shown, in order to enable the first clean water tank 14 to be firmly installed on the housing 121 of the floor brush assembly 12, in some embodiments, a movable positioning structure 1485 can be further provided on the handle part 149 of the first clean water tank 14, and the positioning structure 1485 is used for clamping with the housing 121. When installing the first clean water tank 14 onto the housing 121, the positioning structure 1485 is clamped with the housing 121; when removing the first clean water tank 14 from the housing 121, the positioning structure 1485 is moved so that the positioning structure 1485 is disengaged from the clamping with the housing 121 to take out the first clean water tank 14.

[0280] As an embodiment, the positioning structure 1485 provided on the handle part 149 can include a positioning member 14851 and an elastic member 14852. The positioning member 14851 is movably installed on the handle part 149, and the elastic member 14852 abuts between the positioning member 14851 and the handle part 149. The user can apply an external force to the positioning member 14851 to drive the positioning member 14851 to move. When the positioning member 14851 moves and compresses the elastic member 14852, the elastic force generated by the elastic member 14852 can drive the positioning member 14851 to reset.

[0281] Among them, the positioning member 14851 may include a pressing portion 14851a and a clamping portion 14851b. The pressing portion 14851a and the clamping portion 14851b may be integrally formed. In other words, the positioning member 14851 may be an integrally formed member. The pressing portion 14851a may be movably connected to the handle portion 149, and the clamping portion 14851b passes through the handle portion 149 and extends into the avoidance space surrounded by the two expansion portions 148 (see Figure 19 ). The elastic member 14852 abuts between the pressing portion 14851a and the handle portion 149.

[0282] When the first clean water tank 14 is installed on the housing 121, the elastic force provided by the elastic member 14852 causes the clamping portion 14851b to protrude above the main body portion 147 and be exposed in the space surrounded by the two expansion portions 148, and the clamping portion 14851b is clamped with the housing 121. When separating the first clean water tank 14 from the housing 121, the user presses the pressing portion 14851a of the positioning member 14851, and the clamping portion 14851b of the positioning member 14851 moves downward accordingly. The clamping portion 14851b can move to be hidden in the main body portion 147, and the clamping portion 14851b is disengaged from the clamping with the housing 121 to take out the first clean water tank 14. When the external force applied to the pressing portion 14851a of the positioning member 14851 is eliminated, under the action of the elastic force of the elastic member 14852, the positioning member 14851 moves upward to reset, driving the clamping portion 14851b to move upward to the position where it is clamped with the housing 121.

[0283] Referring to Figure 19 or Figure 22 As shown, in this embodiment, the expansion portion 148 of the first clean water tank 14 is provided with an air inlet valve 1483 and an air outlet valve 1484. The air inlet valve 1483 is used to allow external air to enter the first clean water tank 14, and the air outlet valve 1484 is used to discharge the air in the first clean water tank 14 to the outside.

[0284] During the cleaning operation of the cleaning device 10, the water pump in the floor brush assembly 12 is started, and the cleaning water in the first clean water tank 14 is conveyed to the roller brush 13 through the connection hole 144 of the first clean water tank 14 (see Figure 16 ) to wet the roller brush 13 and enable the roller brush 13 to effectively clean the surface to be cleaned. During this process, the air inlet valve 1483 of the first clean water tank 14 can be in an open state to allow external air to enter the first clean water tank 14, maintain the air pressure in the first clean water tank 14, keep the water outlet flow rate of the first clean water tank 14 normal, and ensure the cleaning effect of the cleaning device 10.

[0285] During the process of filling the first clean water tank 14 with water through the charging base, the first water pump on the charging base starts, and the clean water from the water storage tank or an external water source is conveyed into the first clean water tank 14. During this process, the exhaust valve 1484 of the first clean water tank 14 can be in an open state to discharge the air in the first clean water tank 14 to the outside, so that the clean water can be continuously injected into the first clean water tank 14. During the process of the user manually filling the first clean water tank 14 with water, the exhaust valve 1484 of the first clean water tank 14 can also be in an open state to discharge the air in the first clean water tank 14, so that the clean water is continuously injected into the first clean water tank 14, which will not be elaborated here.

[0286] Moreover, in this embodiment, by providing an exhaust valve 1484 on the expansion part 148 of the first clean water tank 14, the air in the parts separated by the partition of the two expansion parts 148 can be discharged. That is to say, the air in the top spaces of the two expansion parts 148 can be discharged through the exhaust valve 1484 provided on the expansion part 148. In this way, during the process of filling water into the first clean water tank 14, the air in the first clean water tank 14 can be completely discharged, and there is no situation where the air in the top space of the expansion part 148 cannot be discharged. The air in the first clean water tank 14 is completely discharged, and the clean water fully occupies the space in the first clean water tank 14, which can solve the problem that the first clean water tank 14 cannot be filled with water and the water volume cannot reach the capacity of the first clean water tank 14, can avoid the problem that the user frequently adds water during use, and can improve the user experience.

[0287] Figure 24 For Figure 19 the structural schematic diagram of the upper box body of the first clean water tank in Figure 19 and Figure 24 As shown, as an implementation manner, only one of the two expansion parts 148 of the first clean water tank 14 is provided with an exhaust valve 1484, and a communication channel 150 is also provided in the first clean water tank 14. The communication channel 150 extends from one expansion part 148 to the other expansion part 148. The communication channel 150 can be a silicone tube or a plastic housing attachment, and the gas in the two expansion parts 148 can communicate with each other through the communication channel 150.

[0288] Among them, in the two expansion parts 148 of the first clean water tank 14, the intake valve 1483 and the exhaust valve 1484 can both be provided on the same expansion part 148. Or, the intake valve 1483 is provided on one expansion part 148, and the exhaust valve 1484 is provided on the other expansion part 148. This embodiment does not make specific restrictions on this.

[0289] During the process of adding water to the first clean water tank 14, the exhaust valve 1484 needs to be opened to exhaust air outward so that the first clean water tank 14 can be filled with water as much as possible. In this regard, the installation position of the exhaust valve 1484 should be as close as possible to the top of the first clean water tank 14 (in the water-adding state) to facilitate exhausting the air in the first clean water tank 14 as much as possible.

[0290] If the solution of this embodiment is not adopted, during the automatic water injection process of the first clean water tank, as the water level in the first clean water tank rises, the air in the two expansion parts slowly discharges. However, when the water level rises to the position of the expansion part, it will be found that only the expansion part equipped with the exhaust valve can discharge air, and the air in the expansion part without the exhaust valve cannot be discharged smoothly, resulting in the problem that the first clean water tank cannot be filled during the automatic water injection process, thus leading to low utilization rate of the clean water tank and inability to store more clean water.

[0291] In this embodiment, by setting up a communication channel, the two expansion parts are connected. When the water level in the first clean water tank gradually rises to the position of the expansion part, since the indirect air circulation space below the two expansion parts is blocked by water, the air in the expansion part without the exhaust valve can only flow into the expansion part equipped with the exhaust valve through the communication channel, so that a single exhaust valve can be shared for exhaust, enabling the air in both expansion parts to be quickly discharged as the water level rises until the expansion part is filled with water, improving the utilization rate of the clean water tank. Moreover, the setting of the communication channel also accelerates the air intake process of the clean water tank, facilitating the stable and rapid output of the clean water in the clean water tank. Especially during the process of draining water after the clean water tank is full, during this process, the air entering the expansion part equipped with the intake valve can quickly flow into the expansion part without the intake valve through the communication channel, so that air can quickly enter the tops of both expansion parts, forming air pressure at the top of the expansion part, facilitating the stable decline of the water level in the clean water tank, being conducive to the accurate monitoring of the remaining water volume in the clean water tank, and avoiding the situation where the water in the expansion part without the intake valve cannot be discharged at the beginning and needs to wait until the water in the other expansion part equipped with the intake valve is drained before it can be discharged, ensuring the stability during the water discharge process of the clean water tank.

[0292] The following will take the example where both the intake valve 1483 and the exhaust valve 1484 are installed on the same expansion part 148 for illustration.

[0293] For the convenience of description, in this embodiment, the two expansion parts 148 of the first clean water tank 14 are respectively defined as the first expansion part 148a and the second expansion part 148b. And when only one of the two expansion parts 148 is equipped with the intake valve 1483 and the exhaust valve 1484, taking the expansion part 148a where the intake valve 1483 and the exhaust valve 1484 are located as an example for illustration.

[0294] During the process of filling the first clean water tank 14 with water, the cleaning water is conveyed into the first clean water tank 14. When the liquid level of the cleaning water reaches the highest complete liquid level, as the cleaning water is added, the air in the two expansion parts 148 (the parts separated by the partition) is compressed, and the air pressure gradually increases. When the air pressure reaches a certain value, the exhaust valve 1484 of the first expansion part 148a opens. At this time, the air in the first expansion part 148a provided with the exhaust valve 1484 can be directly discharged to the outside through the exhaust valve 1484 of the first expansion part 148a. The air in the second expansion part 148b not provided with the exhaust valve 1484 is conveyed through the communication channel 150 to the first expansion part 148a provided with the exhaust valve 1484 and is discharged to the outside through the exhaust valve 1484 of the first expansion part 148a.

[0295] In this way, the air in the top spaces of the two expansion parts 148 can be completely discharged, and the cleaning water can fill the entire first clean water tank 14, so that the first clean water tank 14 achieves the effect of complete water filling. Thus, it is possible to prevent the user from frequently adding water during the use of the cleaning device 10 and improve the user experience of the cleaning device 10. During this period, the air in the second expansion part 148b is conveyed through the communication channel 150 to the first expansion part 148a, and the air pressures in the first expansion part 148a and the second expansion part 148b always remain balanced, and the liquid levels in the first expansion part 148a and the second expansion part 148b are kept consistent until both the first expansion part 148a and the second expansion part 148b are full of water.

[0296] It should be noted that the aforementioned highest complete liquid level refers to the highest position when the liquid level of the cleaning water is a complete and continuous plane. It can be understood that when the liquid level of the cleaning water contacts the bottom end of the partition part, the liquid level of the cleaning water has not yet reached the space separated by the partition of the two expansion parts 148. At this time, the liquid level of the cleaning water is the highest complete liquid level. If it exceeds this highest complete liquid level, the cleaning water will enter the space separated by the two expansion parts 148, and the liquid level of the cleaning water will be separated into an incomplete and discontinuous liquid level.

[0297] Among them, with reference to Figure 19 or Figure 22 As shown, taking the state when the first clean water tank 14 is installed on the floor brush assembly 12 as a reference, both the air inlet valve 1483 and the exhaust valve 1484 can be arranged at the top of the expansion part 148, and both the air inlet valve 1483 and the exhaust valve 1484 are located at the highest position of the expansion part 148. So that the air in the expansion part 148 can be completely discharged through the exhaust valve 1484, and moreover, it can prevent the cleaning water in the expansion part 148 from overflowing from the air inlet valve 1483 or the exhaust valve 1484, and improve the reliability of the first clean water tank 14.

[0298] Exemplarily, both the intake valve 1483 and the exhaust valve 1484 can be arranged at the top of the side wall of the expansion part 148. Alternatively, both the intake valve 1483 and the exhaust valve 1484 can be arranged on the upper surface of the expansion part 148. Or, one of the intake valve 1483 and the exhaust valve 1484 is arranged on the top wall of the side wall of the expansion part 148, and the other is arranged on the upper surface of the expansion part 148. Among them, when the cross-sectional area of the main expansion part 1481 of the expansion part 148 gradually changes, specifically from one side of the main expansion part 1481 facing the rotary brush 13 to the other side of the main expansion part 1481, when the cross-sectional area of the main expansion part 1481 gradually decreases, both the intake valve 1483 and the exhaust valve 1484 can be arranged on the side of the main expansion part 1481 facing the rotary brush 13.

[0299] Continuing to refer to Figure 19 or Figure 22 As shown, in some embodiments, the first clean water tank 14 can also be provided with a water injection port (not shown in the figure), and a water injection cover 151 is covered at the water injection port. The water injection port is usually arranged at one end in the length direction of the first clean water tank 14. For example, the water injection port is arranged at one end face of one of the first expansion part 148a and the second expansion part 148b away from the other, or the water injection port is arranged at the end face of the main body part 147. In this way, the user can place the first clean water tank 14 vertically so that the water injection port of the first clean water tank 14 faces upward. Furthermore, clean water can be injected into the first clean water tank 14 by manual water injection.

[0300] In this regard, the intake valve 1483 and the exhaust valve 1484 on the first clean water tank 14 can be arranged at the end where the water injection port is located. In this way, when the first clean water tank 14 is placed vertically for manual water injection, both the intake valve 1483 and the exhaust valve 1484 are located at the highest position of the first clean water tank 14. The air in the first clean water tank 14 can be smoothly discharged through the exhaust valve 1484. Moreover, it can also prevent the clean water in the first clean water tank 14 from overflowing outward through the intake valve 1483, ensuring the reliability of the use of the first clean water tank 14.

[0301] Exemplarily, both the intake valve 1483 and the exhaust valve 1484 are located on the side wall at one end in the length direction of the first clean water tank 14. Alternatively, both the intake valve 1483 and the exhaust valve 1484 are located at the end where the water injection port is located on the upper surface of the expansion part 148. Or, one of the intake valve 1483 and the exhaust valve 1484 is located on the side wall at one end in the length direction of the first clean water tank 14, and the other is located at the end where the water injection port is located on the upper surface of the expansion part 148.

[0302] Regarding the setting manner of the communication channel 150 in the first clean water tank 14, refer to Figure 24As shown, as an embodiment, the communication channel 150 can be an independent pipe, and the communication channel 150 is detachably installed in the first clean water tank 14. At this time, the inner wall of the first clean water tank 14 can be provided with a positioning portion 152, and the positioning portion 152 is used to support and position the communication channel 150, so that the communication channel 150 is stably and reliably arranged in the first clean water tank 14. As another embodiment, the communication channel 150 can also be integrally connected to the inner wall of the first clean water tank 14, or in other words, the communication channel 150 can be formed on the inner wall of the first clean water tank 14 by integral molding.

[0303] Figure 25 for Figure 19 A cross-sectional view of the first clean water tank near the connecting passage. Figure 25 As shown, the gap between the two ends of the communication channel 150 and the inner top walls of the two expansion parts 148 can be less than the preset distance, wherein the inner top wall of the expansion part 148 is the inner wall of the expansion part 148 on one side away from the main body 147. In this way, there is a gap between the port of the communication channel 150 and the inner top wall of the expansion part 148, which can ensure that the air in the expansion part 148 can enter the communication channel 150, ensuring that the communication channel 150 can function effectively. In addition, the gap between the port of the communication channel 150 and the inner top wall of the expansion part 148 is small enough, and the port limit of the communication channel 150 is close to the inner top wall of the expansion part 148, so that the air at the top of the expansion part 148 can completely and thoroughly enter the communication channel 150, avoiding that the clean water in the expansion part 148 floods the port of the communication channel 150, so that part of the air cannot enter the communication channel 150 and is retained at the top of the expansion part 148.

[0304] For example, Figure 25 As shown in , when the communication channel 150 is an independent channel and is installed in the first clean water tank 14 in a detachable manner, the inner top wall of the expansion part 148 can be provided with a mounting portion 1486, and the port of the communication channel 150 can be sleeved outside the mounting portion 1486 to fix the two ends of the communication channel 150, so as to ensure that the gap between the end of the communication channel 150 and the inner top wall of the expansion part 148 is less than the preset distance. In addition, the mounting portion 1486 of the inner top wall of the expansion part 148 can be provided with a channel opening 14861, and the communication channel 150 can be connected with the internal space of the expansion part 148 through the channel opening 14861 of the mounting portion 1486, so that the air in the expansion part 148 enters the communication channel 150 through the channel opening 14861 of the mounting portion 1486.

[0305] Figure 26 A structural diagram of another first clean water tank from one perspective provided in an embodiment of the present application. Figure 27 A structural diagram of another first clean water tank from another perspective provided in an embodiment of the present application.

[0306] Referring to Figure 26 and Figure 27 As shown, as another embodiment, air inlet valves 1483 and air outlet valves 1484 can be provided in both expansion parts 148 of the first clean water tank 14. Or rather, an air inlet valve 1483 and an air outlet valve 1484 are provided in both the first expansion part 148a and the second expansion part 148b. At this time, there is no need to provide a communication channel 150 in the first clean water tank 14. The air in the first expansion part 148a can be discharged through the air outlet valve 1484 on the first expansion part 148a, and the air in the second expansion part 148b can be discharged through the air outlet valve 1484 on the second expansion part 148b.

[0307] During the process of filling the first clean water tank 14 with water, the cleaning water is conveyed into the first clean water tank 14. When the liquid level of the cleaning water reaches the highest full liquid level, as the cleaning water is added, the air in both expansion parts 148 (the parts separated by the partition) is compressed, and the air pressure gradually increases. When the air pressure in the first expansion part 148a reaches a certain value, the air outlet valve 1484 of the first expansion part 148a opens, and the air in the first expansion part 148a is discharged to the outside through the air outlet valve 1484 of the first expansion part 148a. Similarly, when the air pressure in the second expansion part 148b reaches a certain value, the air outlet valve 1484 of the second expansion part 148b opens, and the air in the second expansion part 148b is discharged to the outside through the air outlet valve 1484 of the second expansion part 148b.

[0308] In this way, the air in the top spaces of both expansion parts 148 can be completely discharged, and the cleaning water can fill the entire first clean water tank 14, so that the first clean water tank 14 reaches the effect of being completely filled with water. Thus, it is possible to avoid the user from frequently adding water during the use of the cleaning device 10 and improve the user experience of the cleaning device 10. Since the exhaust rates of the first expansion part 148a and the second expansion part 148b are controlled by their respective air outlet valves 1484, the air pressures in the first expansion part 148a and the second expansion part 148b can be balanced or unbalanced, and the liquid levels in the first expansion part 148a and the second expansion part 148b can be the same or different until both the first expansion part 148a and the second expansion part 148b are full of water.

[0309] Continue to refer to Figure 26 and Figure 27, taking the state when the first clear water tank 14 is installed on the floor brush assembly 12 as a reference, the air inlet valve 1483 and the exhaust valve 1484 of the first expansion part 148a can be arranged at the top of the first expansion part 148a, and both the air inlet valve 1483 and the exhaust valve 1484 of the first expansion part 148a are located at the highest position of the first expansion part 148a. So that the air in the first expansion part 148a can be completely discharged through the exhaust valve 1484, and moreover, it can prevent the cleaning water in the first expansion part 148a from overflowing from the air inlet valve 1483 or the exhaust valve 1484, improving the reliability of the first clear water tank 14.

[0310] Exemplarily, both the air inlet valve 1483 and the exhaust valve 1484 of the first expansion part 148a can be arranged at the top of the side wall of the first expansion part 148a. Or, both the air inlet valve 1483 and the exhaust valve 1484 of the first expansion part 148a can be arranged on the upper surface of the first expansion part 148a. Or, one of the air inlet valve 1483 and the exhaust valve 1484 of the first expansion part 148a is arranged on the top wall of the side wall of the first expansion part 148a, and the other is arranged on the upper surface of the first expansion part 148a.

[0311] Similarly, taking the state when the first clear water tank 14 is installed on the floor brush assembly 12 as a reference, the air inlet valve 1483 and the exhaust valve 1484 of the second expansion part 148b can be arranged at the top of the second expansion part 148b, and both the air inlet valve 1483 and the exhaust valve 1484 of the second expansion part 148b are located at the highest position of the second expansion part 148b. So that the air in the second expansion part 148b can be completely discharged through the exhaust valve 1484, and moreover, it can prevent the cleaning water in the second expansion part 148b from overflowing from the air inlet valve 1483 or the exhaust valve 1484, improving the reliability of the first clear water tank 14.

[0312] Exemplarily, both the air inlet valve 1483 and the exhaust valve 1484 of the second expansion part 148b can be arranged at the top of the side wall of the second expansion part 148b. Or, both the air inlet valve 1483 and the exhaust valve 1484 of the second expansion part 148b can be arranged on the upper surface of the second expansion part 148b. Or, one of the air inlet valve 1483 and the exhaust valve 1484 of the second expansion part 148b is arranged on the top wall of the side wall of the second expansion part 148b, and the other is arranged on the upper surface of the second expansion part 148b.

[0313] Wherein, when the cross-sectional area of the main expansion part 1481 of the expansion part 148 gradually changes, specifically from one side of the main expansion part 1481 facing the roller brush 13 to the other side of the main expansion part 1481, when the cross-sectional area of the main expansion part 1481 gradually decreases, both the air inlet valve 1483 and the exhaust valve 1484 can be arranged on the side of the main expansion part 1481 facing the roller brush 13.
