Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water tank assembly and a cleaning device. Background Art

[0002] With the improvement of people's living standards, cleaning devices represented by floor sweepers and floor washers have been gradually popularized and applied. Taking the floor washer as an example, the floor washer includes a floor washer main body and a cleaning base station. A water tank for providing water for mopping is installed on the floor washer main body. After the floor washer main body finishes the cleaning task, it returns to the cleaning base station, and the cleaning base station replenishes clean water to the water tank of the floor washer main body.

[0003] However, in the related art, when the cleaning base station injects water into the water tank of the floor washer main body, it is necessary to pump out the air in the water tank by means of a pump to form a negative pressure in the water tank, and then inject water into the water tank. However, after the water injection is completed, the water tank may still maintain a negative pressure state, resulting in an imbalance between the internal and external air pressures of the water tank, making it difficult to separate from the cleaning base station, or causing jitter when leaving the cleaning base station, affecting the working stability of the floor washer. Summary of the Utility Model

[0004] In view of this, the utility model provides a water tank assembly and a cleaning device to solve the problem that in the related art, during the process of using the cleaning base station to inject water into the water tank of the cleaning assembly, it is easy to cause an imbalance between the internal and external air pressures of the water tank, resulting in difficulty for the water tank to separate from the cleaning base station, or jitter when the water tank separates from the cleaning base station, affecting the working stability of the cleaning device.

[0005] In the first aspect, the utility model provides a water tank assembly, including:

[0006] A water tank, on which an exhaust port and a water injection port are formed;

[0007] A floating member, which is disposed in the water tank in a liftable manner. A first opening, a second opening and a first channel are formed on the floating member. The first opening is disposed at the top of the floating member, and the first channel communicates the first opening and the second opening; the second opening communicates with the exhaust port of the water tank.

[0008] Beneficial effects: During the use of the water tank assembly of the embodiment of the utility model, the cleaning base station can inject water into the water tank through the water injection port of the water tank, so that the water level in the water tank changes. The floating member can rise accordingly, and it is ensured that the first opening is always above the water surface, so as to communicate with the air above the water surface in the water tank. Through such a setting, as the water level rises, the air above the water surface can sequentially pass through the first opening, the first channel, the second opening and the exhaust port and be discharged outside the water tank, so as to avoid the imbalance between the internal and external air pressures of the water tank.

[0009] When the water tank assembly supplies water to the scrubbing member of the cleaning device, causing the water level in the water tank to gradually decrease, external air can enter the water tank through the exhaust port, the second opening, the first channel and the first opening in sequence, thereby avoiding the formation of negative pressure in the water tank.

[0010] Therefore, the water tank assembly of the embodiment of the present application can overcome the problem in the related art that the cleaning assembly is prone to cause an imbalance in the internal and external air pressure of the water tank during the process of using the cleaning base station to fill the water tank with water, making it difficult to separate from the cleaning base station, or the water tank shakes when it separates from the cleaning base station. The water tank assembly of the embodiment of the present application works more stably.

[0011] Furthermore, since the internal and external air pressures of the water tank assembly of the embodiment of the present application are balanced during the water filling process, damage to the structure of the water tank due to excessive pressure difference inside and outside the water tank can be avoided, thereby reducing the risk of water tank damage and water leakage.

[0012] In an optional embodiment, the water inlet is arranged on the side wall or the bottom wall of the water tank, and the floating member further comprises:

[0013] A third opening is provided on a surface of the floating member facing away from the first opening;

[0014] A second channel is formed in the floating member and is used to connect the third opening and the second opening.

[0015] Beneficial effect: Through such a configuration, during the actual use of the cleaning device, the operator can remove the water tank assembly from the main body of the cleaning device, and turn the bottom wall of the water tank assembly upwards, and add water to the water tank assembly through the water filling port. At this time, the third opening of the floating member can be located on the upper side and always above the water surface, so as to be connected with the air above the water surface. As the water level continues to rise, the floating member can rise with the water level in the water tank, and ensure the dynamic balance of the air pressure inside and outside the water tank, and prevent the water tank assembly from leaking during the water filling process.

[0016] In an optional embodiment, the first channel and the second channel are T-shaped cavities.

[0017] Beneficial effect: With such a configuration, a three-way structure is formed in the floating member, and the operator can remove the water tank assembly from the main body of the cleaning device and invert the water tank assembly, thereby injecting water into the water tank assembly through the water injection port. At this time, the third opening of the floating member can be located on the upper side and always above the water surface, thereby communicating with the air above the water surface. As the water level continues to rise, the floating member can rise with the water level in the water tank and ensure the dynamic balance of the air pressure inside and outside the water tank, so that the water tank assembly will not leak due to the pressure difference between the inside and outside.

[0018] On this basis, setting the third opening to communicate with the first opening can also prevent the floating member from being vacuum adsorbed on the top wall of the water tank when it rises to contact the top wall of the water tank. When the user removes the water tank assembly from the cleaning device and inverts the water tank assembly to fill water into the water injection port, the first opening can prevent the floating member from being vacuum adsorbed on the bottom wall of the water tank. In an alternative embodiment, the water tank assembly further includes a limiting member disposed in the water tank and extending in the vertical direction, and the floating member can move between the top surface and the bottom surface of the water tank under the limitation of the limiting member.

[0019] Beneficial effects: The limiting member can limit the movement path of the floating member, ensure that the floating member can rise and fall with the water level, and prevent the limiting member from interfering with other structures in the water tank, resulting in the inability of the limiting member to communicate with the air in the upper part of the water tank.

[0020] In an alternative embodiment, the limiting member includes:

[0021] A tubular main body, with the inner wall of the water tank serving as a partial peripheral wall of the tubular main body, and the two ends of the tubular main body are respectively connected to the top wall and the bottom wall of the water tank;

[0022] A communication port formed on the tubular main body and extending from the top wall of the water tank to the bottom wall of the water tank. At least a part of the floating member is disposed in the tubular main body and communicates with the exhaust port through the communication port.

[0023] Beneficial effects: By setting it in this way, the tubular main body can constrain the movement path of the floating member. The communication port can allow the floating member to communicate with the exhaust port of the water tank assembly. In addition, the communication port is connected to the outside of the tubular main body, and a communicating vessel structure can also be formed to ensure that the water surface inside the tubular main body can rise and fall synchronously with the water level in the water tank, thereby ensuring that the floating member can rise and fall synchronously with the water level in the water tank.

[0024] On this basis, a part of the side wall of the water tank can also serve as the side wall of the limiting member, thereby reducing the material required for the limiting member and at the same time helping to increase the structural strength of the limiting member. On this basis, the limiting member can also serve as a reinforcing rib to enhance the strength of the water tank.

[0025] In an alternative embodiment, the water tank assembly further includes: an exhaust pipe communicating the second opening and the exhaust port of the water tank, and at least a part of the exhaust pipe can bend or move with the rise and fall of the floating member.

[0026] In an alternative embodiment, the exhaust pipe includes:

[0027] A fixed section connected to the exhaust port, and the fixed section is fixedly arranged on the side wall of the water tank through a fixing member;

[0028] A movable section connected between the fixed section and the floating member, and the movable section can bend or move with the rise and fall of the floating member.

[0029] Beneficial effects: By setting it in this way, the fixing part can fixedly set the fixing section on the inner wall of the water tank, thereby reducing the risk of interference between the drain pipe and other components during the lifting process.

[0030] In an alternative embodiment, a sealing structure is provided at the connection between the exhaust pipe and the exhaust port.

[0031] Beneficial effects:

[0032] The sealing structure can reduce the risk of water leakage at the connection between the exhaust pipe and the exhaust port.

[0033] In a second aspect, the present utility model further provides a cleaning device, including:

[0034] A main body, including a water tank assembly as provided in the first aspect of the present utility model;

[0035] A cleaning base for supplying water to the water injection port of the water tank assembly.

[0036] Beneficial effects: The cleaning device in the second aspect of the present utility model includes or uses the water tank assembly in the first aspect of the present utility model, and thus has its beneficial effects, that is, the water tank assembly of the cleaning device in the embodiments of the present application can overcome the problems in the related art that during the process of using a cleaning base station to inject water into the water tank, it is easy to cause an imbalance in the internal and external air pressures of the water tank, making it difficult to separate from the cleaning base station, or there is a shaking problem when the water tank separates from the cleaning base station. The cleaning device in the embodiments of the present application works more stably.

[0037] In an alternative embodiment, the cleaning device further includes:

[0038] A water level detection module, arranged on the main body, for detecting the liquid level in the water tank;

[0039] A control module, communicatively connected to the water level detection module and the cleaning base, and capable of controlling the cleaning base to start or stop supplying water to the water tank assembly based on the liquid level information detected by the water level detection module.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0060] In the related art, when the cleaning base station injects water into the water tank of the floor washer main body, it is necessary to use a pump to extract the air in the water tank to create a negative pressure in the water tank, and then inject water into the water tank. However, when the water injection is completed, the water tank may still maintain a negative pressure state, which will not only cause the air pressure inside and outside the water tank to be unbalanced, increasing the risk of damage to the water tank, but also cause the water tank and the water injection port of the cleaning base station to be pressed tightly under the action of atmospheric pressure, making it difficult to separate from the cleaning base station. Even if it is forcibly separated from the cleaning base station under the action of external force, the water tank will shake when separating from the base station, affecting the working stability of the floor washer.

[0061] In another related art, a one-way exhaust valve is provided at the upper part of the water tank. During the process of injecting water into the clean water tank, the air inside the water tank is continuously squeezed, and the air pressure gradually increases until the exhaust valve is opened. After the exhaust valve is opened, the air pressure inside the water tank is relieved through the exhaust valve, and the air pressure inside and outside the water tank finally reaches a balanced state. However, if the water injection speed is too fast, the air pressure inside the water tank will increase rapidly. Since the water tank structure is not integrally formed and is composed of multiple parts processed and connected, in the environment where the air pressure inside the water tank increases rapidly, water leakage is likely to occur at the joints of each part. In addition, the air pressure difference between the inside and outside of the water tank is too large, which will cause damage to the structure of the water tank 1 in the long term, easily resulting in water leakage, and noise and vibration will also be generated during pressure relief.

[0062] The following will be described in conjunction with Figures 1 to 10 , the embodiments of the present utility model.

[0063] According to an embodiment of the present utility model, on the one hand, a water tank assembly is provided, including a water tank 1 and a floating member 2. Among them, an exhaust port 101 and a water injection port 102 are formed on the water tank 1. The floating member 2 is disposed in the water tank 1 in a liftable manner, and a first opening 201, a second opening 202, and a first channel 203 are formed on the floating member 2. The first channel 203 communicates the first opening 201 and the second opening 202; the second opening 202 communicates with the exhaust port 101 of the water tank 1.

[0064] During the use of the water tank assembly according to the embodiment of the present utility model, the cleaning base station can inject water into the water tank 1 through the water injection port 102 of the water tank 1, so that the water level in the water tank 1 changes. The floating member 2 can rise accordingly, and it is ensured that the first opening 201 is always above the water surface, so as to communicate with the air above the water surface in the water tank 1. By such setting, as the water level rises, the air above the water surface can be discharged out of the water tank 1 through the first opening 201, the first channel 203, the second opening 202 and the exhaust port 101 in sequence, so as to avoid the imbalance of the internal and external air pressures of the water tank 1.

[0065] When the water tank assembly supplies water to the scrubbing member of the cleaning device, causing the water level in the water tank 1 to gradually decrease, the external air can enter the water tank 1 through the exhaust port 101, the second opening 202, the first channel 203 and the first opening 201 in sequence, so as to avoid the formation of negative pressure in the water tank 1.

[0066] Therefore, the water tank assembly according to the embodiment of the present application can overcome the problems in the related art that during the process of the cleaning assembly injecting water into the water tank 1 using the cleaning base station, it is easy to cause the imbalance of the internal and external air pressures of the water tank 1, making it difficult to separate from the cleaning base station, or the water tank 1 shakes when it separates from the cleaning base station. The water tank assembly according to the embodiment of the present application works more stably.

[0067] Moreover, since the internal and external air pressures of the water tank assembly according to the embodiment of the present application are balanced during the water injection process, it can also avoid damage to the structure of the water tank 1 caused by too large a difference in the internal and external air pressures of the water tank 1, and reduce the risk of water leakage due to damage to the water tank 1.

[0068] Wherein, the top of the water tank 1 refers to the upward-facing side of the water tank 1 in the state of using the cleaning base station for the water tank 1. It is usually at the top of the cleaning device.

[0069] In one embodiment, the water tank assembly further includes an exhaust pipe 3. The exhaust pipe 3 communicates the second opening 202 with the exhaust port 101, and at least a part of the exhaust pipe 3 can bend or move along with the lifting of the floating member 2 (see Figures 5 to 7 ).

[0070] As a transformable implementation manner, the second opening 202 of the floating member 2 is communicated with the exhaust port 101 through a flexible airbag.

[0071] In one embodiment, the exhaust port 101 is formed on the top surface of the water tank 1.

[0072] As a transformable implementation manner, the exhaust port 101 can also be alternatively formed on the side wall or the bottom wall of the water tank 1, as long as it can communicate with the outside.

[0073] The floating member 2 is preferably but not limited to being made of materials with a density less than that of water, such as foam or plastic.

[0074] It should be noted that in the embodiment of the present application, no limitation is imposed on the shape of the floating member 2. For example, Figure 4 As shown, a plane is formed at the bottom of the floating member 2. By such an arrangement, the floating member 2 can be prevented from turning over during the process of rising and falling with the water level, ensuring that the operation of the water tank assembly is more stable.

[0075] In a preferred embodiment, the floating member 2 is a cylindrical floating ball, which has a simple manufacturing process and can ensure that the floating member 2 is more stable during the lifting process and is not prone to overturning.

[0076] The water tank assembly may be optionally used in a cleaning device, and the cleaning device is preferably but not limited to a floor scrubber, a fabric cleaning machine or a sweeping robot.

[0077] In one embodiment, the water inlet 102 is disposed on the side wall or the bottom wall of the water tank 1, and the floating member 2 further includes a third opening 204 and a second channel 205. The third opening 204 is disposed on a side surface of the floating member 2 away from the first opening 201. The second channel 205 is formed in the floating member 2 for connecting the third opening 204 and the second opening 202.

[0078] By such arrangement, in the actual use of the cleaning device, the operator can remove the water tank assembly from the main body 6 of the cleaning device, and turn the bottom wall of the water tank assembly upwards, and add water to the water tank assembly by himself through the water filling port 102. At this time, the third opening 204 of the floating member 2 can be located on the upper side and always above the water surface, so as to be connected with the air above the water surface. As the water level continues to rise, the floating member 2 can rise with the water level in the water tank 1, and ensure the dynamic balance of the air pressure inside and outside the water tank 1, and prevent the water tank assembly from leaking during the water replenishment process.

[0079] The exhaust pipe 3 may be connected to the middle position of the floating member 2 . As a convertible embodiment, the exhaust pipe 3 may also be connected to the upper or lower position of the floating member 2 .

[0080] In one embodiment, the first channel 203 and the second channel 205 are T-shaped cavities.

[0081] By such arrangement, a three-way structure is formed in the floating member 2, and the operator can remove the water tank assembly from the main body 6 of the cleaning device and invert the water tank assembly, thereby filling water into the water tank assembly through the water injection port 102. At this time, the third opening 204 of the floating member 2 can be located on the upper side and always above the water surface, thereby communicating with the air above the water surface. As the water level continues to rise, the floating member 2 can rise with the water level in the water tank 1 and ensure the dynamic balance of the air pressure inside and outside the water tank 1, so that the water tank assembly will not leak due to the pressure difference between the inside and outside.

[0082] On this basis, setting the third opening 204 to communicate with the first opening 201 can also prevent the floating member 2 from being vacuum adsorbed on the top wall of the water tank 1 when the floating member 2 rises to contact the top wall of the water tank 1. When the user removes the water tank assembly from the cleaning device and inverts the water tank assembly to inject water into the water injection port 102, the first opening 201 can prevent the floating member 2 from being vacuum adsorbed on the bottom wall of the water tank 1.

[0083] As a transformable embodiment, the first channel 203 and the second channel 205 can also be selected to form a cavity in the shape of a Y or other shapes, as long as it can ensure that both the first opening 201 and the third opening 204 are communicated with the second opening 202.

[0084] In one embodiment, the water tank assembly further includes a limiting member 4. The limiting member 4 is disposed in the water tank 1 and extends in the vertical direction, and the floating member 2 can move between the top surface and the bottom surface of the water tank 1 under the limitation of the limiting member 4.

[0085] The limiting member 4 can limit the movement path of the floating member 2, ensure that the floating member 2 can rise and fall with the water level, and prevent the limiting member 4 from interfering with other structures in the water tank 1, resulting in the inability of the limiting member 4 to communicate with the air in the upper part of the water tank 1.

[0086] In one embodiment, the limiting member 4 is formed on the inner wall of the water tank 1.

[0087] It should be noted that in the embodiments of the present application, the specific position of the setting of the limiting member 4 is not limited, as long as the effect that the floating member 2 can move back and forth between the bottom surface and the top surface of the water tank 1 can be achieved.

[0088] As a transformable embodiment, the limiting member 4 can also be selected to be disposed in the middle of the water tank 1.

[0089] In one embodiment, the limiting member 4 includes a tubular main body and a communication port. Among them, the inner wall of the water tank 1 serves as a part of the peripheral wall of the tubular main body, and the two ends of the tubular main body are respectively connected to the top wall and the bottom wall of the water tank 1. The communication port is formed on the tubular main body and extends from the top wall of the water tank 1 to the bottom wall of the water tank 1. The floating member 2 is at least partially disposed in the tubular main body and is communicated with the exhaust port 101 through the communication port. By setting like this, the tubular main body can restrict the movement path of the floating member 2. The communication port can allow the floating member 2 to communicate with the exhaust port 101. In addition, the communication port is communicated with the outside of the tubular main body, and a communicating vessel structure can also be formed to ensure that the water surface inside the tubular main body can rise and fall synchronously with the water level in the water tank 1, so as to ensure that the floating member 2 can rise and fall synchronously with the water level in the water tank 1.

[0090] On this basis, part of the side wall of the water tank 1 can also serve as the side wall of the limiting member 4, thereby reducing the material required for the limiting member 4 and at the same time helping to increase the structural strength of the limiting member 4. On this basis, the limiting member 4 can also serve as a reinforcing rib to enhance the strength of the water tank 1.

[0091] As a transformable embodiment, in an embodiment not shown, the inner wall of the water tank 1 is recessed outward to form a limiting groove.

[0092] In one embodiment, as Figure 5 and Figure 6 shown, ribs are formed protruding on the side wall of the water tank 1, and the ribs and the side wall of the water tank 1 together enclose a limiting groove.

[0093] As a transformable embodiment, in an embodiment not shown, a limiting groove is formed on one of the limiting member 4 and the floating member 2, and a limiting protrusion is formed on the other of the limiting member 4 and the floating member 2, and the limiting protrusion can slide along the limiting groove.

[0094] Specifically, the limiting member 4 can be selected to include a limiting groove formed on the water tank 1, the limiting groove extends in the vertical direction, and the floating member 2 is arranged in the limiting groove in a liftable manner.

[0095] As a transformable embodiment, the limiting member 4 includes a limiting protrusion formed on the water tank 1, the limiting protrusion extends in the vertical direction, and a limiting groove is formed on the floating member 2, and the limiting groove is sleeved on the limiting protrusion.

[0096] In one embodiment, the water injection port 102 is provided on the bottom wall of the water tank 1.

[0097] When the main body 6 of the cleaning device carrying the water tank assembly returns to the cleaning base station for water replenishment, the cleaning base station can replenish water into the water tank 1 through the water injection port 102.

[0098] In one embodiment, the exhaust pipe 3 passes through the communication port to connect the second opening 202 and the exhaust port 101, and at least a part of the exhaust pipe 3 can be bent or moved along with the lifting of the floating member 2. In one embodiment, the exhaust pipe 3 includes a fixed section 301 and a movable section 302. Among them, the fixed section 301 is connected to the exhaust port 101, and the fixed section 301 is fixedly arranged on the side wall of the water tank 1 through a fixing member 5. The movable section 302 is connected between the fixed section 301 and the floating member 2, and the movable section 302 can be bent or moved along with the lifting of the floating member 2.

[0099] By setting it like this, the fixing member 5 can fixedly arrange the fixed section 301 on the inner wall of the water tank 1, thereby reducing the risk of interference between the drain pipe and other components during the lifting process.

[0100] Among them, the fixing member 5 is preferably but not limited to a snap member, a riveting member or a magnetic attraction member assembly.

[0101] Exemplarily, as Figure 7 described, the fixing member 5 includes a buckle formed on the inner wall of the water tank 1.

[0102] As an alternative embodiment, when the fixing member 5 is selected as a riveting member or a bolt connection assembly, connection lugs may be formed on the outer periphery of the exhaust pipe 3, and connection holes for bolts or rivets to pass through may be formed on the inner wall of the water tank 1.

[0103] In one embodiment, the hardness of the fixed section 301 is greater than that of the movable section 302.

[0104] By setting it like this, the risk of deformation of the fixed section 301 can be further reduced.

[0105] As an alternative embodiment, the exhaust pipe 3 is a hose with uniform hardness, which can reduce the processing difficulty of the exhaust pipe 3.

[0106] In one embodiment, a sealing structure is provided at the connection between the exhaust pipe 3 and the exhaust port 101.

[0107] By setting it like this, the risk of water leakage at the connection between the exhaust pipe 3 and the exhaust port 101 can be reduced.

[0108] Exemplarily, the sealing structure may be selected to include a sealing ring clamped between the exhaust pipe 3 and the exhaust port 101.

[0109] As an alternative embodiment, a sealing joint is formed at one end of the exhaust pipe 3 for connecting to the exhaust port 101. The sealing joint is inserted on the exhaust port 101, and the sealing joint can serve as a sealing structure.

[0110] In one embodiment, a water outlet 103 is formed on the bottom wall of the water tank 1.

[0111] By setting it like this, during the use of the cleaning device, the water in the water tank assembly can provide clear water to the scrubbing member of the cleaning device through the water outlet 103.

[0112] According to an embodiment of the present invention, on the other hand, a cleaning device is also provided, including a main body 6 and a cleaning base. Among them, the main body 6 includes the water tank assembly provided in the first aspect of the present invention. The cleaning base is used to supply water to the water injection port 102 of the water tank assembly.

[0113] The cleaning device according to the second aspect of the present utility model includes or uses the water tank assembly according to the first aspect of the present utility model, and thus has its beneficial effects, that is, the water tank assembly of the cleaning device according to the embodiments of the present application can overcome the problems in the related art that during the process of filling water into the water tank 1 by using the cleaning base station for the cleaning assembly, it is easy to cause the imbalance of the internal and external air pressures of the water tank 1, making it difficult to separate from the cleaning base station, or the water tank 1 shakes when separating from the cleaning base station. The cleaning device according to the embodiments of the present application works more stably.

[0114] Next, the working process of the cleaning assembly according to the embodiments of the present application will be described:

[0115] When the cleaning assembly according to the embodiments of the present application performs the cleaning work, the water outlet 103 of the water tank assembly can be opened to supply water to the scrubbing member of the cleaning assembly.

[0116] During the process of the cleaning assembly performing the cleaning work, the water level in the water tank assembly gradually drops, the air in the water tank 1 increases, the pressure becomes smaller, and the atmosphere sequentially enters the inside of the water tank 1 through the exhaust port 101, the exhaust pipe 3 and the floating member 2 to ensure the air pressure balance inside and outside the water tank 1.

[0117] When the cleaning work is over, the main body 6 carries the water tank assembly back to the cleaning base station, the water filling port 102 of the water tank assembly is opened, and the cleaning base station replenishes water to the water tank assembly through the water filling port 102. During the water replenishing process, the liquid level in the water tank 1 rises accordingly, the pressure inside the water tank 1 becomes larger, and the floating member 2 is lifted with the water level in the sliding limit inlet structure under the buoyancy force, ensuring that the first opening 201 on the upper surface of the floating member 2 is always higher than the water surface, so that the inside of the water tank 1 can always be connected to the outside air, and the air flow inside the water tank 1 can be discharged to the outside of the water tank 1 through the floating member 2, the exhaust pipe 3 and the exhaust port 101 in sequence, so that during the rising of the water level, the dynamic balance of the internal and external air pressures of the water tank 1 is always maintained, and no water leakage phenomenon caused by the internal and external pressure difference will occur.

[0118] Among them, the scrubbing member preferably but is not limited to including a squeegee or a roller brush 7, etc.

[0119] In one embodiment, the cleaning device further includes a water level detection module and a control module. Among them, the water level detection module is arranged on the main body 6 and is used to detect the liquid level in the water tank 1. The control module is communicatively connected to the water level detection module and the cleaning base, and can control the cleaning base to start or stop supplying water to the water tank assembly based on the liquid level information detected by the water level detection module. In one embodiment, the control module can control the cleaning base to stop supplying water to the water tank assembly when the water level value detected by the water level detection module is higher than or equal to a first preset water level. The first preset water level can be selected as the water level when the water tank assembly is full of water.

[0120] In one embodiment, the control module is further capable of controlling the cleaning base to supply water into the water tank assembly when the water level value detected by the water level detection module is lower than a second preset water level. The second preset water level can be selected as the water level when the water volume in the water tank assembly is insufficient.

[0121] In one embodiment, the water level detection module is arranged in the water tank 1.

[0122] The control module may include a programmable logic control component (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well-known to those skilled in the art and will not be elaborated here.

[0123] In one embodiment, the water injection port 102 is connected to the cleaning base through a first valve, and the water outlet 103 is connected to the roller brush 7 through a second valve. The first valve and the second valve are communicatively connected to the control module.

[0124] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
