The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

In the related art, the cleaning liquid tank and the clean water tank are integrated, and the cleaning liquid and clean water are mixed by pumping the cleaning liquid in the cleaning liquid tank into the clean water tank. This structure is inconvenient for adding cleaning liquid, and the cleaning liquid tank and the clean water tank need to be removed together. The complicated cleaning liquid adding structure also leads to a rough overall design of the self-cleaning maintenance station. The exposed handle makes the structure untidy and is not convenient for adding cleaning liquid.

To this end, an embodiment of the present disclosure provides a self-cleaning maintenance station, which includes a maintenance station body, a clean water tank and a cleaning liquid tank, wherein the cleaning liquid tank is assembled or removed from the maintenance station body in a direction substantially perpendicular to the assembly direction of the clean water tank, wherein the cleaning liquid tank includes a cleaning liquid tank shell and a cleaning liquid tank end cover, wherein the cleaning liquid tank end cover is arranged to be attached to the front side of the cleaning liquid tank shell, and the cleaning liquid tank end cover is configured such that when the cleaning liquid tank is assembled on the maintenance station body, the cleaning liquid tank end cover is substantially flush with the outer surface of the maintenance station body.

The cleaning liquid tank end cover of the present disclosure is arranged to fit on the front side of the cleaning liquid tank shell, and the cleaning liquid tank end cover is configured so that when the cleaning liquid tank is assembled on the maintenance station body, the cleaning liquid tank end cover is flush with the outer surface of the maintenance station body, thereby ensuring the simple appearance of the self-cleaning maintenance station. The hidden buckle makes it easy to extract the cleaning liquid tank at any time, while also ensuring the simple appearance of the self-cleaning maintenance station. Moreover, when the automatic cleaning device is located on the self-cleaning maintenance station for maintenance, the operation button of the automatic cleaning device is usually located on the inner side of the self-cleaning maintenance station. When the user wants to manually operate the above-mentioned operation button, the design method of the cleaning liquid tank end cover being flush with the outer surface of the maintenance station body will not block the user's hand movements, which is more convenient for the user to operate.

Specifically, an embodiment of the present disclosure provides a self-cleaning maintenance station. As an example, FIG1 is a schematic diagram of the overall structure of the self-cleaning maintenance station of some embodiments of the present disclosure; FIG2 is a schematic diagram of the assembly structure of the cleaning liquid tank in the self-cleaning maintenance station of some embodiments of the present disclosure.

In order to more clearly describe the behavior of the self-cleaning maintenance station, the following directions are defined: the self-cleaning maintenance station can be calibrated by defining the following three mutually perpendicular axes: the lateral axis Y, the front-to-back axis X, and the central vertical axis Z. The direction opposite to the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device enters the self-cleaning maintenance station, is marked as "rearward", and the direction along the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device leaves the self-cleaning maintenance station, is marked as "forward". The lateral axis Y is essentially along the width of the self-cleaning maintenance station body, along The direction of the arrow along the transverse axis Y is the "left side" of the self-cleaning maintenance station, and the opposite direction of the arrow along the transverse axis Y is the "right side" of the self-cleaning maintenance station. The vertical axis Z is the direction extending upward along the bottom surface of the self-cleaning maintenance station, the direction of the arrow along the vertical axis Z is the "upper side" of the self-cleaning maintenance station, and the opposite direction of the arrow along the vertical axis Z is the "lower side" of the self-cleaning maintenance station.

As shown in Figure 1, the self-cleaning maintenance station provided in this embodiment includes a self-cleaning maintenance station base plate 1000 and a self-cleaning maintenance station body 2000, wherein the self-cleaning maintenance station base plate 1000 and the self-cleaning maintenance station body 2000 are detachably or non-detachably connected, and the detachable connection facilitates the transportation and maintenance of the self-cleaning maintenance station base plate 1000 and the self-cleaning maintenance station body 2000.

As shown in Figure 2, the self-cleaning maintenance station body 2000 includes a water storage chamber 2700 and a dust collecting chamber 2800. The water storage chamber 2700 is opened upward and is arranged at the top of the self-cleaning maintenance station body 2000. The water storage chamber includes a clean water chamber for accommodating a clean water tank and a sewage chamber for accommodating a sewage tank 5000. The dust collecting chamber 2800 is opened upward and is arranged side by side with the water storage chamber 2700 at the top of the self-cleaning maintenance station body 2000. The upward design of the water storage chamber 2700 and the dust collecting chamber 2800 facilitates the installation and removal of the clean water tank, the sewage tank 5000 and the dust collecting hood 6000. The clean water tank, the sewage tank 5000 and the dust collecting hood 6000 are all assembled or removed in a roughly vertical direction from the top of the self-cleaning maintenance station body 2000. This structural design conforms to the user's usage habits. In addition, the upward design facilitates daily maintenance of the devices in the clean water tank, the sewage tank 5000 and the dust collecting hood 6000.

As shown in Figure 2, the water storage chamber 2700 and the dust collecting chamber 2800 are surrounded by the rear wall, front wall and multiple side walls of the self-cleaning maintenance station body 2000. The rear wall and front wall of the water storage chamber 2700 and the dust collecting chamber 2800 are coplanar, and one side wall is coplanar. The height of the rear wall of the self-cleaning maintenance station body 2000 is slightly lower than the height of the front wall of the self-cleaning maintenance station body 2000. The front wall of the self-cleaning maintenance station body 2000 is equivalent to the height of the clean water tank, the sewage tank 5000 and the dust hood 6000. The side wall of the self-cleaning maintenance station body 2000 connects the rear wall and the front wall, and the end face of the side wall of the self-cleaning maintenance station body 2000 is a slope structure. The upward design of the water storage chamber 2700 and the dust collection chamber 2800 facilitates the installation and removal of the clean water tank 4000, the sewage tank 5000 and the dust collection cover 6000, wherein the end surface of the side wall is an inclined structure to ensure the stability and aesthetics of the clean water tank, the sewage tank 5000 and the dust collection cover 6000 installed in the water storage chamber 2700 and the dust collection chamber 2800. The water storage chamber 2700 is used to accommodate the clean water tank and the sewage tank 5000, wherein the water storage chamber 2700 includes a vertically extending partition, which divides the water storage chamber 2700 into two parts, one part is a clean water chamber for accommodating the clean water tank 4000, and the other part is a sewage chamber for accommodating the sewage tank 5000.

The outer wall of the self-cleaning maintenance station body 2000 wraps the water storage chamber 2700 and the dust collecting chamber 2800 to form a U-shaped wrapping structure, for example, wrapping at least a portion of the front side wall and the left and right side walls of the water storage chamber 2700 and the dust collecting chamber 2800, so that when the clean water tank 4000, the sewage tank 5000 and the dust hood 6000 are assembled to the top of the self-cleaning maintenance station body 2000, the clean water tank 4000, the sewage tank 5000 and the dust hood 6000 are not exposed to the outside on the front and rear sides of the self-cleaning maintenance station body 2000, thereby increasing the overall beauty and neatness of the self-cleaning maintenance station.

The lower part of the self-cleaning maintenance station body 2000 and the bottom plate 1000 of the self-cleaning maintenance station together form a cleaning chamber 2100 that opens forward, and the cleaning chamber 2100 is used to accommodate the automatic cleaning device when the automatic cleaning device returns to the self-cleaning maintenance station for maintenance operations. A cleaning tank 2200 is provided at the bottom of the self-cleaning maintenance station body, and is configured so that when the automatic cleaning device is adapted to the cleaning chamber 2100, the cleaning parts on the automatic cleaning device, such as a mop, are cleaned through the cleaning tank 2200.

As shown in FIG. 2 , the maintenance station body 2000 further includes a cleaning liquid chamber 2400, which is arranged on the maintenance station body 2000 along an opening direction substantially perpendicular to the water storage chamber 2700, i.e., the cleaning liquid chamber 2400 is arranged front and back in the horizontal direction, and the cleaning liquid tank 3000 is assembled or removed from the maintenance station body 2000 along a direction substantially perpendicular to the assembly direction of the clean water tank 4000, i.e., the cleaning liquid tank 3000 is removed from the maintenance station body 2000 in a drawer-like manner substantially along the front and back direction. The opening position of the cleaning liquid chamber 2400 is located at the inclined surface 2300 of the upper edge of the cleaning chamber 2100.

The cleaning liquid chamber 2400 is located at the lower side of the water storage chamber 2700. The clean water tank 4000 is drawn roughly along the up and down direction in the water storage chamber 2700, and the cleaning liquid tank 3000 is drawn roughly along the front and back direction in the cleaning liquid chamber 2400. The two do not interfere with each other and are drawn independently. The cleaning liquid tank 3000 is located at the lower side of the clean water tank 4000 to save space and make it more convenient for users to replenish cleaning liquid.

In some embodiments, slide rails (or slide ways) (not shown) are provided on both sides of the cleaning liquid chamber 2400, and slide ways (or slide rails) 3400 are provided on the outer walls of both sides of the cleaning liquid tank 3000. The slide ways (or slide rails) 3400 of the cleaning liquid tank 3000 slide along the slide rails (or slide ways) of the cleaning liquid chamber 2400 to extract the cleaning liquid from the cleaning liquid chamber 2400.

As shown in Figure 3, the cleaning liquid tank 3000 includes a cleaning liquid tank shell 3100 and a cleaning liquid tank end cover 3200. The cleaning liquid tank shell 3100 and the cleaning liquid tank end cover 3200 are integrally injection molded or formed by bonding. The cleaning liquid tank end cover 3200 is arranged to be attached to the front side of the cleaning liquid tank shell 3100. The cleaning liquid tank end cover 3200 is configured so that when the cleaning liquid tank 3000 is assembled on the maintenance station body 2000, the cleaning liquid tank end cover 3200 is flush with the outer surface of the maintenance station body 2000.

In some implementations, the cleaning liquid tank shell 3100 is tilted on one side where it fits with the cleaning liquid tank end cover 3200, and the cleaning liquid tank end cover 3200 is fitted along the front side of the tilted cleaning liquid tank shell 3100. The projection surface of the cleaning liquid tank shell 3100 on the cleaning liquid tank end cover 3200 is located within the inner surface of the cleaning liquid tank end cover 3200, that is, the area of the cleaning liquid tank end cover 3200 is slightly larger than the area of the front side of the cleaning liquid tank shell 3100. As shown in FIG1 , an inclined surface 2300 is provided at the upper edge of the cleaning chamber 2100 at a position where it connects with the outer peripheral surface of the water storage chamber 2700, so that the maintenance station body 2000 forms an inclined surface structure at the edge of the cleaning chamber 2100, and the inclined surface structure facilitates the automatic cleaning equipment to enter and exit the cleaning chamber 2100. The cleaning liquid tank end cover 3200 is fitted along the front side of the tilted cleaning liquid tank shell 3100. The inclination angle of the rear cover 3200 is the same as the inclination angle of the inclined surface 2300, so that after the cleaning liquid tank 3000 is inserted into the cleaning liquid cavity 2400, the cleaning liquid tank end cover 3200 is flush with the inclined surface 2300 to ensure that the automatic cleaning equipment can freely enter and exit the cleaning cavity 2100, and the inclined surface 2300 remains smooth and tidy.

The cleaning liquid tank end cover 3200 has an edge portion 3210, which is arranged around the cleaning liquid tank end cover 3200. The edge portion 3210 extends toward the maintenance station body 2000 in a direction roughly perpendicular to the surface of the cleaning liquid tank end cover 3200, so that after the cleaning liquid tank 3000 is inserted into the cleaning liquid cavity 2400, the cleaning liquid tank end cover 3200 is completely buckled with the edge of the cleaning liquid cavity 2400, ensuring that the cleaning liquid tank end cover 3200 is flush with the inclined surface 2300.

In some embodiments, as shown in FIG. 3-4, the cleaning liquid tank housing 3100 is roughly a rectangular parallelepiped structure, and may also be other structures such as a cylinder, which is not limited to this. The following is an explanation using a rectangular parallelepiped structure as an example. The cleaning liquid tank housing 3100 includes an inclined front side surface (not shown), a top surface 3190, a bottom surface 3160, and left and right side surfaces and a rear side surface (not shown), wherein a slideway (or slide rail) 3400 is provided on the left and right side surfaces. In some embodiments, the top surface 3190 of the cleaning liquid tank housing is a transparent structure, and the user can observe the liquid level of the cleaning liquid through the transparent top surface 3190. A plurality of reinforcing ribs are provided inside at least the left and right sides of the cleaning liquid tank housing 3100 to strengthen the strength of the cleaning liquid tank housing 3100 and prevent the cleaning liquid tank housing 3100 from being deformed after multiple pulling and pulling, thereby affecting the subsequent pulling and pulling smoothness.

In some embodiments, as shown in FIGS. 3-4 , the cleaning liquid tank housing 3100 includes a liquid replenishing port 3110, which is disposed on the top surface 3190 of the cleaning liquid tank housing and is located on a side of the cleaning liquid tank housing 3100 away from the cleaning liquid tank end cap 3200, and the liquid replenishing port 3110 is configured to add cleaning liquid from the liquid replenishing port 3110 when the cleaning liquid tank 3000 is withdrawn from the maintenance station body 2000. Optionally, the liquid replenishing port 3110 is disposed near the inner edge of the cleaning liquid tank housing 3100, for example, disposed in the innermost corner of the cleaning liquid tank housing 3100, and the liquid replenishing port completely leaks out when the cleaning liquid tank 3000 is completely withdrawn from the maintenance station body 2000, and then the cleaning liquid is added, thereby avoiding the inconvenience of adding cleaning liquid when the cleaning liquid tank 3000 is not withdrawn, and also avoiding the risk of spilling the cleaning liquid when the cleaning liquid is added when the cleaning liquid tank 3000 is not withdrawn.

In this embodiment, the refill port 3110 includes a refill hole 3114 and a refill cover 3111. A refill plug 3113 is provided on the lower surface of the refill cover 3111. The refill plug 3113 is inserted into the refill hole 3114 to achieve a sealed closure of the refill port 3110. Optionally, the refill cover 3111 is formed of hard plastic, and the refill plug 3113 is formed of elastic plastic or rubber material. In some embodiments, the refill port 3110 also includes a pivot hole 3116 provided at the edge of the refill hole 3114. A pivot shaft 3115 is provided at the corresponding end of the refill cover 3111. The pivot shaft 3115 is inserted into the pivot hole 3116 to achieve free rotation to cooperate with the opening and closing of the refill cover 3111. In some embodiments, a hand grip 3112 is further provided on the side of the liquid replenishing hole 3114 away from the pivot hole 3116. The hand grip 3112 is a recessed structure, which is convenient for the user to insert his finger into the hand grip 3112 to open the liquid replenishing cover 3111. Optionally, the hand grip 3112 is provided close to the rear side, and the liquid replenishing cover 3111 is opened from the back to the front of the cleaning liquid tank 3000. This design also forces the user to open the liquid replenishing port 3110 to add cleaning liquid only after completely pulling out the cleaning liquid tank 3000.

In some embodiments, as shown in Figure 5, the cleaning liquid tank 3000 includes a cleaning liquid filter 3120, which is arranged on the bottom surface of the cleaning liquid tank shell 3100. When extracting the cleaning liquid, the cleaning liquid is first filtered through the cleaning liquid filter 3120, and then drawn out of the cleaning liquid tank 3000 through the cleaning liquid pipe 3130 and the cleaning liquid outlet 3140. The cleaning liquid filter 3120 filters the cleaning liquid to prevent impurities from damaging the cleaning liquid pump 3300 or components in subsequent circulation channels.

In some embodiments, the cleaning liquid tank further comprises a float valve 3150, which is disposed in the cleaning liquid tank 3000 and is used to detect the liquid level of the cleaning liquid and whether the cleaning liquid tank is assembled on the maintenance station body. In some embodiments, the float valve 3150 uses a small float, which takes up little space and is low in cost, and can increase the amount of cleaning liquid that can be contained in the cleaning liquid tank. Moreover, since the volume of the small float is small, it has little effect on the volume of the cleaning liquid contained in the cleaning liquid tank, and can increase the rotation sensitivity of the float, thereby increasing the detection sensitivity. In some embodiments, the float valve 3150 includes a cleaning liquid float base and a cleaning liquid float. The liquid float base is disposed at the bottom of the cleaning liquid tank 3000. The cleaning liquid float is rotatably connected to the cleaning liquid float base and is configured to detect the cleaning liquid level. The cleaning liquid float drops as the cleaning liquid level decreases under the action of gravity. When the cleaning liquid float drops to a preset threshold, the controller recognizes that the cleaning liquid in the cleaning liquid tank 3000 is exhausted and issues a warning to add cleaning liquid. In some embodiments, the maintenance station body 2000 includes a cleaning liquid status indicator. When the cleaning liquid level is lower than a preset threshold, the cleaning liquid status indicator is controlled to light up.

In some embodiments, the maintenance station body includes a Hall element (not shown), which is disposed on the maintenance station body. Optionally, the Hall element is disposed on the rear wall of the cleaning liquid chamber 2400. A magnetic element is disposed in the float valve 3150. The magnetic element senses the Hall element to detect the liquid level of the cleaning liquid and whether the cleaning liquid tank is installed on the maintenance station body. For example, when the magnetic element is far away from the Hall element and there is no sensing signal, the system alarms, indicating that the cleaning liquid tank is not installed in a suitable position on the maintenance station body and needs to be reinstalled, or that the cleaning liquid level is lower than a threshold and cleaning liquid needs to be added.

In some embodiments, as shown in FIG6 , the cleaning liquid tank housing 3100 includes a recessed portion 3170, which is located on a side of the cleaning liquid tank housing 3100 away from the cleaning liquid tank end cover 3200. Optionally, the recessed portion 3170 is located at the junction of the bottom surface 3160 and the rear side surface of the cleaning liquid tank housing 3100. The recessed portion 3170 forms a notch at the rear of the bottom surface of the cleaning liquid tank housing 3100, and the recessed portion 3170 forms a recessed portion protrusion 3171 at a corresponding position inside the cleaning liquid tank housing 3100. As shown in FIG5 , a limiting column 3180 extends from the recessed portion 3170 in a direction roughly perpendicular to the bottom surface 3160. The limiting column 3180 is located in the recessed portion, and the limiting column 3180 may be a circular The column or prism structure is not limited to this. In order to reduce the material consumption, the limiting column 3180 can be a hollow structure. The bottom surface 3160 of the cleaning liquid tank housing 3100 includes a plurality of reinforcing ribs for reinforcing the strength of the bottom surface 3160 .

The maintenance station body 2000 includes a limiting claw 2420. Optionally, the limiting claw 2420 is arranged on the rear side wall of the cleaning liquid chamber 2400 through a fixing device 2430. Optionally, the limiting claw is an elastic member. The limiting claw 2420 is configured so that when the cleaning liquid tank 3000 is assembled in the cleaning liquid chamber 2400, the limiting column 3180 extends into the elastic limiting claw 2420, and the elastic limiting claw 2420 opens and embraces the limiting column 3180. The limiting claw 2420 is locked with the limiting column 3180, and the cleaning liquid tank 3000 cannot slide inward further, so that the cleaning liquid tank end cover 3200 is flush with the front side inclined surface of the maintenance station body 2000. When the cleaning liquid tank 3000 is pulled out of the cleaning liquid cavity 2400, the limiting claw 2420 opens and releases the limiting column 3180 under the action of elastic force, so that the cleaning liquid tank 3000 can be completely pulled out of the cleaning liquid cavity 2400. Optionally, the limiting claw 3180 is two arc-shaped spring pieces in a natural state, and the ends of the two arc-shaped spring pieces have arc-shaped ends open outward, so that the limiting column 3180 can enter the two arc-shaped spring pieces. When the limiting claw 3180 is locked with the limiting column 3180, the two arc-shaped spring pieces hold the limiting column 3180 tightly.
