Description

[Technical field]

[0001] (Related Applications) This application is based on and claims priority to a Chinese patent application having application number 202111675742.0 and filed on December 31, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the technical field of cleaning robots, and in particular to a self-cleaning maintenance station and a self-cleaning system. [Background technology]

[0003] In recent years, with the progress of science and technology, various cleaning products have appeared one after another, which can reduce the burden of people's cleaning and cleaning tasks, meet people's needs, and provide great convenience to people's lives. Here, automatic cleaning devices are favored by people due to their highly intelligent characteristics.

[0004] In an automatic cleaning device that can sweep and mop floors, the automatic cleaning device sweeps and absorbs dust and dirt from the area to be cleaned, and wet mops the area, after which the user can manually dispose of the dirt in the dust box after the automatic cleaning device has finished cleaning. For areas with a lot of dust and dirt that are difficult to clean, the dust box space of the automatic cleaning device body is limited, so the dust box needs to be manually cleaned frequently during cleaning, which greatly reduces the cleaning efficiency and also has a negative impact on the user experience due to the frequent cleaning of the dust box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the accompanying drawings, but obviously, the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative labor are all included in the protection scope of the present disclosure.

[0011] The terms used in the embodiments of the present disclosure are used only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure.

[0012] It should be noted that the term "and / or" as used herein is merely an explanation of the relationship between related objects, and there are three relationships; for example, A and / or B means that A may exist alone, A and B may exist simultaneously, or B may exist alone. In addition, in this specification, " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0013] In addition, in the embodiments of the present disclosure, terms such as first, second, and third may be used for explanation, but it should be understood that they should not be limited to these terms. These terms are used only for distinction. For example, the first may be called the second, and similarly, the second may be called the first, without departing from the scope of the embodiments of the present disclosure.

[0014] It should be noted that the terms "comprises," "has," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a product or device that includes a set of elements not only includes those elements, but also includes other elements explicitly listed or inherent in those products or devices. Unless further limited, an element defined with the term "comprises" does not exclude the presence of other identical elements in a product or device that includes said element.

[0015] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0016] In the related art, the structure of the self-cleaning maintenance station is usually complex, the water tank is located within a complex hood cover of the self-cleaning maintenance station, making it difficult to remove and use, and the water tank connection port is formed at the bottom of the water tank, making it easy for the water in the water tank to overflow and very likely to damage components in the self-cleaning maintenance station, and further, the air duct of the self-cleaning maintenance station is also too complex, making it difficult for garbage to enter the dust box into the dust collection bin.

[0017] Therefore, the embodiment of the present disclosure provides a self-cleaning maintenance station, and exposes the water tank and dust collection cover to the outside of the self-cleaning maintenance station body, making it easy for users to install and use. At the same time, the water inlet (i.e., the water inlet and outlet) is provided at the top of the self-cleaning maintenance station body, making it difficult for water to overflow from the water tank, and the air duct is directly disposed on the side wall of the self-cleaning maintenance station body, shortening the air duct path and improving dust collection efficiency. Specifically, an example of a self-cleaning maintenance station provided by the embodiment of the present disclosure is shown. FIG. 1 is a schematic diagram illustrating an example of the overall structure of the self-cleaning maintenance station, and FIG. 2 is a schematic diagram illustrating an example of the structure of the self-cleaning maintenance station body after removing the dirty water tank, clean water tank, and dust collection cover of the present disclosure.

[0018] To more clearly describe the behavior of the self-cleaning maintenance station, the following directions are defined: the self-cleaning maintenance station is defined by three mutually perpendicular axes: a lateral axis Y, a front-to-rear axis X, and a central vertical axis Z. The direction opposite to the arrow along the front-to-rear axis X, i.e., the direction in which the automatic cleaning device enters the self-cleaning maintenance station, is defined as "rear", and the direction of the arrow along the front-to-rear axis X, i.e., the direction in which the automatic cleaning device leaves the self-cleaning maintenance station, is defined as "forward". The lateral axis Y is substantially along the width of the body of the self-cleaning maintenance station. The vertical axis Z is a direction that extends upwardly along the bottom surface of the self-cleaning maintenance station.

[0019] As shown in FIG. 1 , the direction in which the self-cleaning maintenance station bottom plate 1000 protrudes from the self-cleaning maintenance station main body 2000 is the forward direction, the direction of the rear wall of the self-cleaning maintenance station main body 2000 is the rear direction, the dust collection bin 3000 is on the left side of the self-cleaning maintenance station, the purified water tank 4000 is on the right side of the dust collection bin 3000, and the dirty water tank 5000 is on the right side of the purified water tank 4000.

[0020] As shown in FIG. 1, the self-cleaning maintenance station provided by this embodiment includes a self-cleaning maintenance station bottom plate 1000, a self-cleaning maintenance station main body 2000, and a dust collection bin 3000, a purified water tank 4000, and a dirty water tank 5000 arranged in line with the self-cleaning maintenance station main body 2000. Here, in order to facilitate transportation and maintenance of the self-cleaning maintenance station bottom plate 1000 and the self-cleaning maintenance station main body 2000, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to the self-cleaning maintenance station main body 2000. As shown in FIG. 2, the self-cleaning maintenance station main body 2000 includes a water storage chamber 2700, a dust collection chamber 2100, and an air duct (air duct 2500 shown in FIG. 6 and FIG. 15). The water storage chamber 2700 opens upward and forward and is arranged at the top of the self-cleaning maintenance station main body 2000. The water storage chamber 2700 includes a purified water chamber 2400 for accommodating a purified water tank 4000 and a dirty water chamber 2300 for accommodating a dirty water tank 5000. The dust collection chamber 2100 opens upward and forward and is provided at the top end of the self-cleaning maintenance station body 2000 alongside the water storage chamber 2700. The dust collection chamber 2100 constitutes a dust collection bin 3000 for accommodating a dust collection cover 2800. As the water storage chamber 2700 and the dust collection chamber 2100 are designed to face upward and forward, dust can be easily collected. The water tank 5000, the purified water tank 4000 and the dust collection cover 2800 can be easily attached and detached. Usually, the dirty water tank 5000, the purified water tank 4000 and the dust collection cover 2800 are all assembled to the self-cleaning maintenance station main body 2000 from the front and upward direction. This structural design conforms to the usage habits of users. Furthermore, the upward and forward opening design makes it convenient for daily maintenance of the components in the water storage chamber 2700 and the dust collection chamber 2100.By exposing at least a portion of the water tank to the outside of the self-cleaning maintenance station main body 2000, it is easier for the user to attach and remove it, and it is easier for the user to visually observe the water level of the liquid inside the tank. Compared to a design in which the entire water tank is located inside the water storage chamber, the exposed design means that when the user removes the water tank, they do not have to lift it beyond the highest point of the cavity and then translate it to remove it, reducing the user's lifting stroke and allowing the user to easily remove the water tank from within the cavity.

[0021] The self-cleaning maintenance station body 2000 further includes an air duct (air duct 2500 shown in FIG. 6 and FIG. 15), at least a part of which is provided on the side wall of the self-cleaning maintenance station body 2000, and the body base 6000 at the bottom of the self-cleaning maintenance station body 2000 and the dust collection chamber 2100 communicate with each other through the air duct, and in the dust collection process, the dust in the dust box enters the air duct through the dust collection port of the body base 6000 and enters the dust collection chamber 2100 through the air duct. The self-cleaning maintenance station body 2000 is configured to collect the dust in the dust box of the automatic cleaning device. The self-cleaning maintenance station body base 6000 has a dust collection port 6100, which is configured to connect with the dust outlet of the automatic cleaning device, and the dust in the dust box of the automatic cleaning device enters the dust collection bin 3000 of the self-cleaning maintenance station body 2000 through the dust collection port 6100. A sealing rubber gasket is further provided around the dust collection port 6100, which is used to seal the dust collection port 6100 after it is connected to the dust outlet of the automatic cleaning device, thereby ensuring the dust collection effect and preventing dust leakage.

[0022] As shown in FIG. 2, the water storage chamber 2700 and the dust collection chamber 2100 are formed by being surrounded by the rear wall, front wall and multiple side walls of the self-cleaning maintenance station main body 2000, the rear wall and the front wall of the water storage chamber 2700 and the dust collection chamber 2100 are respectively flush with each other, and one side wall shares a surface, in which the height of the rear wall of the self-cleaning maintenance station main body 2000 is higher than the height of the front wall of the self-cleaning maintenance station main body 2000, the side wall of the self-cleaning maintenance station main body 2000 is connected to the rear wall and the front wall, and the end surface of the side wall of the self-cleaning maintenance station main body 2000 has an arc-shaped structure. The water storage chamber 2700 and the dust collection chamber 2100 are designed to face upward and forward, making it easy to attach and detach the wastewater tank 5000, the purified water tank 4000 and the dust collection cover 2800, while the arc-shaped structure ensures the stability and aesthetics of the wastewater tank 5000, the purified water tank 4000 and the dust collection cover 2800 attached to the water storage chamber 2700 and the dust collection chamber 2100.

[0023] The water storage chamber 2700 is used to accommodate the dirty water tank 5000 and the purified water tank 4000, and the water storage chamber 2700 is attached to the rear wall of the water storage chamber 2700, and includes a boss 2600 that extends upward at the bottom of the water storage chamber 2700 so as to be slightly lower than the height of the rear wall of the water storage chamber, and a plurality of soft rubber protrusion openings are provided at the top of the boss, and the soft rubber protrusion openings are configured to be connected to the dirty water tank 5000 or the purified water tank 4000 assembled at the corresponding position. Here, the water storage chamber 2700 includes a partition plate 2710 that extends vertically, and the water storage chamber 2700 is divided into two parts, one part is the dirty water chamber 2300 for accommodating the dirty water tank 5000, and the other part is the purified water chamber 2400 for accommodating the purified water tank 4000.

[0024] In some embodiments, the soft rubber protrusion opening includes an air pump port 2610 and a wastewater tank connection port 2620, which are provided corresponding to the top end of the boss 2600 at the assembly position of the wastewater tank 5000, and the air pump sucks out the air in the wastewater tank 5000 through the air pump port 2610, and since the wastewater tank 5000 has a sealed structure, negative pressure is generated inside during the air sucking process, and the wastewater in the cleaning groove is sucked into the wastewater tank 5000 through the wastewater pipe and the wastewater tank connection port 2620. The purified water tank connection port 2630 is provided corresponding to the top end of the boss 2600 at the assembly position of the purified water tank 4000, and the purified water in the purified water tank 4000 flows through the purified water tank connection port 2630 to the squeegee member in the cleaning groove under the action of the peristaltic pump, and cleans the cleaning head of the automatic cleaning device. The air pump port 2610, the wastewater tank connection port 2620, and the purified water tank connection port 2630 are located at the top end of the boss 2600, thereby preventing the water in the purified water tank or the wastewater tank from overflowing from the water tank and flowing into the purified water chamber or the wastewater chamber during the process of replacing the purified water tank or the wastewater tank. The air pump port 2610, the wastewater tank connection port 2620, and the purified water tank connection port 2630 are sealed at the top end of the wastewater tank 5000 and the purified water tank 4000, making the operation more convenient than connecting them at the bottom end of the purified water chamber or the wastewater chamber.

[0025] The self-cleaning maintenance station further includes a dirty water tank 5000 and a purified water tank 4000 arranged side by side in the water storage chamber, and a dust collection cover 2800 arranged side by side in the dust collection chamber 2100, and the top surfaces of the dirty water tank 5000, the purified water tank 4000 and the dust collection cover 2800 are substantially flush with each other, and the front surfaces of the dirty water tank 5000, the purified water tank 4000 and the dust collection cover 2800 are substantially flush with each other. After being assembled into the self-cleaning maintenance station body 2000, the dirty water tank 5000, the purified water tank 4000 and the dust collection cover 2800 are formed into a flat arrangement structure, which is convenient for installation and removal, and has a flat outer shape, which improves aesthetics and enhances user experience.

[0026] When the self-cleaning maintenance station is used for a long time, the soft rubber protrusion openings are inevitably contaminated by dirty water from cleaning the cleaning member, and dirt remains. With the above design, the soft rubber protrusion openings on the boss 2600 have an open structure with respect to the front wall and also have an open structure with respect to the side wall, allowing the arm or cleaning tool to contact the soft rubber protrusion openings from any angle, and allowing the user to easily clean the dirt accumulated around the soft rubber protrusion openings.

[0027] When the sewage tank 5000 and the purified water tank 4000 are assembled in the water storage chamber 2700, the top surfaces of the sewage tank 5000 and the purified water tank 4000 are higher than the rear wall of the self-cleaning maintenance station main body 2000, and most of the tank bodies of the sewage tank 5000 and the purified water tank 4000 are located outside the water storage chamber 2700, and when the dust collection cover 2800 is assembled in the dust collection chamber 2100, the top surface of the dust collection cover 2800 is higher than the rear wall of the self-cleaning maintenance station main body 2000, and most of the dust collection cover 2800 is located outside the dust collection chamber 2100. According to the above design, the amount of material used in the main body of the self-cleaning maintenance station is reduced; the tops of the sewage tank, purified water tank and dust collection cover are exposed to the outside of the cavity, so that people can easily lift the handles on the tops of the sewage tank, purified water tank and dust collection cover, and easily operate the sewage tank, purified water tank and dust collection chamber; and the technical effect of an aesthetic design is also achieved; at the same time, the top of the main body of the self-cleaning maintenance station is designed with a low front wall and a high rear wall, so that the upper positions of the front of the sewage tank, purified water tank and dust collection cover are also exposed to the outside of the cavity at the same time, so that people can easily observe the water level in the transparent sewage tank and purified water tank and the situation in the dust collection chamber, and can timely perform the corresponding operations of the sewage tank, purified water tank and dust collection chamber.

[0028] The dust collection cover 2800 has an opening that is sealed to the end face of the dust collection chamber 2100, and the opening is sealed to the end face of the dust collection bin 3000. The sealed connection completely seals the inside of the dust collection bin 3000, contributing to improved dust collection efficiency.

[0029] The lower part of the self-cleaning maintenance station main body 2000 and the main body base 6000 form a cleaning chamber that opens forward, and the cleaning chamber is used to accommodate the automatic cleaning device when it returns to the self-cleaning maintenance station for maintenance operation. A cleaning groove is provided at the bottom of the self-cleaning maintenance station main body, and is configured to clean the cleaning member of the automatic cleaning device through the cleaning groove after the automatic cleaning device is accommodated in the cleaning chamber.

[0030] After the automatic cleaning device, for example a cleaning robot, returns to the self-cleaning maintenance station after completing cleaning, the automatic cleaning device moves along the inclined surface of the bottom plate 1000 of the self-cleaning maintenance station to the main body base 6000, so that the dust outlet of the automatic cleaning device is connected to the dust collection port 6100 of the main body base 6000, and the garbage in the dust box of the automatic cleaning device is transferred into the dust collection bin 3000 of the self-cleaning maintenance station main body 2000.

[0031] In some embodiments, the main body base 6000 and the main body 2000 are formed as a whole and cannot be detached from each other, and the main body base 6000 further includes a dust collection duct, which is provided in the main body base 6000 and configured to collect dust in the automatic cleaning device. The air intake of the dust collection duct is a dust collection port, and the air exhaust of the dust collection duct communicates with the dust collection chamber 2100 via an air duct.

[0032] In an embodiment of the present disclosure, a dust collection bin for accommodating a dust collection cover is provided at the top end of the self-cleaning maintenance station body, thereby achieving the technical effect of collecting dust at once after the automatic cleaning device has cleaned multiple times, and avoiding the problems of reduced cleaning efficiency and poor user experience caused by frequent cleaning of the dust collection box of the automatic cleaning device.

[0033] In the related art, the structure of the self-cleaning maintenance station is usually complex, the water tank is located within a complex hood cover of the self-cleaning maintenance station, making it difficult to remove and use, and the water tank connection port is formed at the bottom of the water tank, making it easy for the water in the water tank to overflow, and it is very likely that components in the self-cleaning maintenance station will be damaged.

[0034] Therefore, the embodiment of the present disclosure provides a self-cleaning maintenance station, and by exposing at least a part of the water tank to the outside of the self-cleaning maintenance station body, it is easy for the user to attach and detach it, and by providing the water inlet of the water tank at the top of the water tank, the liquid in the water tank is unlikely to overflow, and damage to electronic components due to overflowing liquid can be avoided. Similar structures have similar technical effects, and some of the technical effects will not be repeated here.

[0035] Specifically, an example of a self-cleaning maintenance station provided by an embodiment of the present disclosure is shown in Fig. 1. Fig. 2 is a schematic diagram showing an example of the structure of the self-cleaning maintenance station body after removing the dirty water tank, clean water tank, and dust collection cover of the present disclosure. Figs. 3 to 5 are schematic diagrams showing the water storage tank of the self-cleaning maintenance station of the present disclosure from different perspectives.

[0036] 1, the self-cleaning maintenance station provided by this embodiment includes a self-cleaning maintenance station bottom plate 1000, a self-cleaning maintenance station body 2000, and a water tank 7000. Here, in order to facilitate transportation and maintenance of the self-cleaning maintenance station bottom plate 1000 and the self-cleaning maintenance station body 2000, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to the self-cleaning maintenance station body 2000, and the water tank 7000 is assembled to the top end of the self-cleaning maintenance station body 2000.

[0037] As shown in FIG. 2, the self-cleaning maintenance station body 2000 includes a water storage chamber 2700, which opens upward and forward and is provided at the top of the self-cleaning maintenance station body 2000. The water storage chamber 2700 is configured to accommodate a water storage tank 7000. The water storage tank 7000 may be the purified water tank 4000 or the dirty water tank 5000. The water storage tank 7000 may be multiple. In some embodiments, the self-cleaning maintenance station body 2000 includes two water storage tanks 7000, which are the purified water tank 4000 and the dirty water tank 5000, respectively, and the water storage chamber 2700 includes a purified water chamber 2400 for accommodating the purified water tank 4000 and a dirty water chamber 2300 for accommodating the dirty water tank 5000, correspondingly. The water chamber 2700 is designed to open upward and forward, and the water tank 7000 is assembled to the self-cleaning maintenance station body 2000 from the front and top, which is more in line with the usage habits of users and can facilitate the installation and removal of the water tank 7000. Furthermore, the upward and forward opening design makes it easier to perform daily maintenance on the components in the water chamber 2700.

[0038] The water storage chamber 2700 is surrounded by the rear wall, front wall and a number of side walls of the self-cleaning maintenance station body 2000, where the height of the rear wall of the self-cleaning maintenance station body 2000 is higher than the height of the front wall of the self-cleaning maintenance station body 2000, the side walls of the self-cleaning maintenance station body 2000 connect the rear wall and the front wall, and the end faces of the side walls of the self-cleaning maintenance station body 2000 have an arc-shaped structure. The arc-shaped structure can ensure the stability and aesthetics of the water storage tank 7000 attached to the water storage chamber 2700.

[0039] The water chamber 2700 further includes a rear wall that fits into the water chamber 2700 and a boss 2600 that extends upward from the bottom of the water chamber 2700 to a height slightly lower than the height of the rear wall of the water chamber. The height of the boss 2600 is higher than the height of the maximum water level line of the water tank 7000, and when the water tank 7000 is assembled to the water chamber 2700, the boss 2600 supports a water tank protrusion (water tank protrusion 7140 shown in Figures 3 and 4) of the water tank 7000.

[0040] A number of soft rubber protrusion openings are provided on the top of the boss 2600, which are used to connect to the water tank 7000 assembled at the corresponding position. Specifically, the soft rubber protrusion openings are used to connect to the waste water outlet or clean water outlet provided on the water tank 7000.

[0041] In some embodiments, the soft rubber protrusion opening includes an air pump port 2610 and a wastewater tank connection port 2620 located corresponding to the top end of the boss 2600 at the assembly position of the wastewater tank 5000, and the air pump sucks out the air in the wastewater tank 5000 through the air pump port 2610. Since the wastewater tank 5000 has a sealed structure, negative pressure is formed inside during the air sucking process, and the wastewater in the cleaning groove is sucked into the wastewater tank 5000 through the wastewater pipe and the wastewater tank connection port 2620.

[0042] In some embodiments, the soft rubber protrusion opening further includes a purified water tank connection port 2630 provided corresponding to the top end of the boss 2600 in the assembly position of the purified water tank 4000, and the purified water in the purified water tank 4000 flows into the squeegee member in the cleaning groove through the purified water tank connection port 2630 under the action of the peristaltic pump to clean the cleaning head of the automatic cleaning device.

[0043] The air pump port 2610, the dirty water tank connection port 2620, and the purified water tank connection port 2630 are provided at the top end of the boss 2600, to prevent the water in the purified water tank or the dirty water tank from overflowing from the water tank and flowing into the purified water chamber or the dirty water chamber during the process of replacing the purified water tank or the dirty water tank. The air pump port 2610, the dirty water tank connection port 2620, and the purified water tank connection port 2630 are connected at the top end with the dirty water tank 5000 and the purified water tank 4000, and the operation is more convenient than the connection at the bottom end of the purified water chamber or the dirty water chamber.

[0044] When the self-cleaning maintenance station is used for a long time, the soft rubber protrusion openings are inevitably contaminated by dirty water from cleaning the cleaning member, and dirt remains. With the above design, the soft rubber protrusion openings on the boss 2600 have an open structure with respect to the front wall and also have an open structure with respect to the side wall, allowing the arm or cleaning tool to contact the soft rubber protrusion openings from any angle, and allowing the user to easily clean the dirt accumulated around the soft rubber protrusion openings.

[0045] In some embodiments, the top of the boss 2600 may be provided with a plurality of soft rubber protrusion points 2640, which are adapted to correspond to the pits 7221 (shown in FIG. 5) provided on the underside of the water tank protrusion (water tank protrusion 7140 shown in FIG. 3 and FIG. 4) of the water tank 7000. When the water tank 7000 is assembled to the water chamber 2700, the soft rubber protrusion points 2640 of the water chamber 2700 are limited to the pits 7221 of the water tank 7000. The specific number of the soft rubber protrusion points 2640 may be set according to the actual situation, and the soft rubber protrusion points 2640 may be distributed symmetrically on the top of the boss 2600. For example, in one embodiment, the soft rubber protrusion points 2640 are four, and are distributed approximately evenly on the top of the boss 2600. The soft rubber protrusions 2640 fit into the pits 7221 to regulate the position, so that the position of the water tank 7000 in the water storage chamber 2700 becomes more accurate, and displacement of the water tank 7000 can be prevented.

[0046] The water storage chamber 2700 may further include a vertically extending partition plate 2710, which divides the water storage chamber 2700 into two parts, one part being a dirty water chamber 2300 for accommodating a dirty water tank 5000, and the other part being a purified water chamber 2400 for accommodating a purified water tank 4000. At least one vibration damping pad 2711 is provided on the top end of the partition plate 2710, configured to support the handle and reduce vibration of the handle when the handle is dropped. At least one position control protrusion (not shown) is provided on each side of the partition plate 2710, and at least one position control recess (second recess 7120 shown in Figures 3 and 4) that fits the position control protrusion is provided on the side walls of the wastewater tank and the purified water tank facing the partition plate 2710, and after the wastewater tank and the purified water tank are assembled into the wastewater chamber and the purified water chamber, the position control protrusion engages with the position control recess to control the position.

[0047] The water tank 7000 is detachably assembled on the top end of the self-cleaning maintenance station body 2000, specifically, the water tank 7000 is detachably assembled in the water chamber 2700. The detachable assembly of the water tank 7000 and the upward and forward opening design of the water chamber 2700 make it very easy to attach and detach the water tank 7000, which is convenient for users to daily replace the liquid in the water tank 7000. The water tank 7000 may adopt a transparent material to observe the water level in the water tank 7000.

The dirty water tank 5000 and the purified water tank 4000 are arranged side by side in the water storage chamber 2700, and the top surfaces of the dirty water tank 5000 and the purified water tank 4000 are substantially flush with each other, and the front surfaces are substantially flush with each other. After the dirty water tank 5000 and the purified water tank 4000 are assembled into the self-cleaning maintenance station body 2000, they are formed into a flat arrangement structure, which is convenient for installation and removal on the one hand, and has a flat outer shape, which improves aesthetics and improves user experience on the other hand.

[0050] The water tank 7000 has an opening for the inflow or outflow of liquid. The opening is provided at the top of the tank body, and the height of the opening is higher than the maximum water level line 7111 of the water tank 7000. If the water tank 7000 is a purified water tank 4000, the opening is a purified water port, and if the water tank 7000 is a sewage tank 5000, the opening is a sewage port. If the height of the opening is higher than the maximum water level line of the water tank 7000, the liquid in the water tank 7000 will not overflow from the water tank, and the overflow of liquid can be prevented, especially during the water tank replacement process. Furthermore, damage to electronic components caused by overflowing liquid can be avoided.

[0051] Referring to Figures 3 to 5 together, the water tank 7000 includes a water tank accommodating portion 7100 and a water tank top cover 7200, the water tank top cover 7200 substantially covers the water tank accommodating portion 7100, the water tank accommodating portion 7100 includes a water tank main body portion 7130 and a water tank protrusion portion 7140, the water tank top cover 7200 forms a cavity together with the water tank accommodating portion 7100, the water tank protrusion portion 7140 protrudes from the water tank main body portion 7130, and the water tank has a substantially L-shaped structure.

[0052] The water tank housing 7100 is used to contain liquid. The sidewall of the water tank housing 7100 includes at least one recess extending upward along the bottom of the water tank housing, and the recess is fitted with a protrusion in the water storage chamber 2700 to restrict its position. In some specific embodiments, the sidewall of the water tank housing 7100 includes a first recess 7110 extending upward along the bottom of the water tank housing until it exceeds a maximum water level line 7111, and a second recess 7120 extending upward along the bottom of the water tank housing to a preset height, and the height of the second recess 7120 is not limited. Here, the first recess 7110 is fitted with at least a part of the boss 2600 to regulate its position, the top surface of the first recess 7110 forms at least a part of the bottom surface of the water tank protruding part 7140, the top surface of the first recess 7110 includes a clean water port, a dirty water port or a pit 7221, etc., and is connected to the air pump port 2610, the dirty water tank connection port 2620, the clean water tank connection port 2630 or the soft rubber protrusion point 2640 provided on the boss 2600, and the second recess 7120 is fitted with a protrusion on the inner side wall of the water storage chamber 2700 to regulate its position. The recess provided in the water tank receiving part 7100 achieves the overall regulation of the position of the water storage tank 7000, and the water storage tank 7000 is relatively accurately provided at the corresponding position of the water storage chamber 2700, thereby preventing the water storage tank 7000 from being displaced.

[0053] The top cover 7200 covers the top of the water tank housing part 7100, and is detachably connected to the water tank housing part 7100, and the top cover 7200 can be opened and closed relative to the water tank housing part 7100. When the top cover 7200 is closed, the liquid in the water tank housing part 7100 is isolated from the outside, and it is possible to prevent external foreign objects from dropping into the water tank 7000. Optionally, when the top cover 7200 is closed, the top cover 7200 comes into sealing contact with the water tank housing part 7100, and the top cover 7200 forms a sealed structure together with the water tank housing part 7100.

[0054] A clean water port, a dirty water port or a pit 7221, etc. are provided on the underside of the water tank protrusion 7140. When the water tank 7000 is a dirty water tank 5000, a dirty water port is provided on the underside of the water tank protrusion 7140.

After the air pump port 2610 is connected to the air pump interface, it can suck dirty water from the dirty water tank 5000. In some embodiments, the air pump sucks out the air in the dirty water tank 5000 through the air pump port 2610 and the air pump interface, and since the dirty water tank 5000 has a sealed structure, negative pressure is formed inside during the air sucking process, and the dirty water in the washing groove is sucked into the dirty water tank 5000 through the dirty water pipe and the dirty water tank connection port 2620.

[0056] A plurality of pits 7221 may be further provided on the underside of the water tank protrusion 7140. When the water tank 7000 is assembled in the water chamber 2700, the water tank protrusion 7140 is just supported by the boss 2600 in the water chamber 2700, and the plurality of pits 7221 provided on the underside of the water tank protrusion 7140 cooperate with the soft rubber protrusion point 2640 on the top of the boss 2600 to achieve position regulation of the water tank 7000. The soft rubber protrusion point 2640 fits into the pit 7221 to regulate the position, so that the position of the water tank 7000 in the water chamber 2700 becomes more accurate, and deviation of the position of the water tank 7000 can be avoided.

[0057] 5, in some embodiments, the water tank 7000 is the purified water tank 4000, and the water tank 7000 may further include a water pipe bracket 7300 and a water pipe 7400. The water pipe bracket 7300 is provided on a protruding structure 7900 in the purified water tank 4000, and the protruding structure 7900 is formed corresponding to the first recess 7110, and the protruding structure 7900 is higher than the maximum water level line of the purified water tank 4000. The water pipe 7400 extends from the water pipe bracket 7300 to the bottom of the purified water tank 4000, and the liquid flows to the outside of the purified water tank 4000 through the water pipe 7400. The water pipe 7400 has a water pipe inlet and a water pipe outlet, where the water pipe inlet is located at the bottom of the purified water tank 4000, the water pipe outlet is located at the water pipe bracket 7300, and the water pipe outlet is connected to the purified water port of the purified water tank 4000.

[0058] In some embodiments, the water tank 7000 is the purified water tank 4000, and the water tank 7000 may further include a float base 7500 and a float 7600. Here, the float base 7500 is provided at the bottom of the purified water tank 4000 and is used to position the float 7600, and the float 7600 is connected to the float base 7500 and can rotate around an axis fixed on the float base 7500, and is configured to detect the water level in the tank.

[0059] In some embodiments, the water tank 7000 is the purified water tank 4000, where the water tank 7000 may further include a filter 7700. The filter 7700 is disposed at the end of the water tube inlet and configured to filter the liquid as it enters the water tube 7400.

[0060] The water tank 7000 may further include a handle 7800. The handle 7800 may be hinged to the top of the water tank 7000. The handle 7800 may make the water tank 7000 easier to attach and remove, and may facilitate routine replacement of the liquid in the water tank 7000 by a user.

[0061] An embodiment of the present disclosure provides a self-cleaning maintenance station, in which at least a portion of the water tank is exposed to the outside of the self-cleaning maintenance station body, making it convenient for users to attach and detach. By locating the water inlet of the water tank at the top of the water tank, the liquid in the water tank is less likely to overflow, and damage to electronic components caused by overflowing liquid can be avoided.

[0062] In the related art, the self-cleaning maintenance station fan is installed in a fan bin, the fan bin is installed at the bottom of the dust collection bin, and an air vent is formed at the bottom of the dust collection bin, and the air in the dust collection bin is sucked out by the suction force generated when the fan is operated, and is discharged to the outside of the self-cleaning maintenance station body 2000 through the air duct in the fan bin. Since the distance between the dust collection port and the cleaning groove is relatively short, the residual water in the cleaning groove may be brought into the dust collection port when the robot climbs up and down the pile, and if the amount of water is too much, water may be sucked into the dust collection bin through the air duct during fan operation, and if too much water accumulates in the dust collection bin, there is a risk of damage to the fan or electric shock.

[0063] Therefore, the embodiment of the present disclosure provides a self-cleaning maintenance station, and the drainage hole is provided at the bottom of the dust collection bin, so that the liquid in the dust collection bin can be immediately discharged, and the same structure has the same technical effect, and some of the technical effects are not repeated here. Specifically, as shown in Figures 1 and 2, the self-cleaning maintenance station includes a self-cleaning maintenance station bottom plate 1000 and a self-cleaning maintenance station body 2000, and the bottom plate 1000 is detachably or non-detachably connected to the self-cleaning maintenance station body 2000, which is convenient for transportation. The self-cleaning maintenance station body 2000 includes a dust collection chamber 2100, and a dust collection cover 2800 is provided to cover the dust collection chamber 2100 to form a dust collection bin 3000, and the dust collection chamber 2100 is integrally provided at the top end of the self-cleaning maintenance station body 2000. As shown in FIG. 6 , the dust collection chamber 2100 is recessed inward at the top end of the self-cleaning maintenance station body 2000 to form a dust collection chamber 2100 for accommodating various parts for dust collection, and the dust collection chamber 2100 has a drainage hole 2101, which is provided at the bottom of the dust collection chamber. The drainage hole 2101 may be one or more, and may be set according to the internal space of the dust collection chamber 2100. The drainage hole 2101 is usually provided at a low position at the bottom of the dust collection chamber, which is convenient for discharging liquid, and the self-cleaning maintenance station body 2000 is provided with an air duct. The self-cleaning maintenance station further includes an air duct 2500, one end of which is connected to a dust collection port 6100 of the main body base 6000 and the other end of which is connected to the dust collection chamber 2100. A side wall of the dust collection chamber 2100 includes an air intake port 2102 which is connected to the dust collection port 6100 of the main body base 6000 via the air duct 2500. The air duct is formed in the side wall of the self-cleaning maintenance station main body 2000 and extends downward, passing through the main body base 6000 and connected to the dust collection port 6100 of the main body base 6000.Here, when the self-cleaning maintenance station is in a dust collection state, the internal airflow of the dust collection bin 3000 is connected to the outside of the dust collection bin 3000 through the air duct 2500, and the drain hole 2101 is not connected to the outside of the dust collection bin 3000, so that a sufficient negative pressure is maintained within the dust collection bin, and the dust in the dust box is sucked into the dust collection bag through the dust collection port and the air duct. When the self-cleaning maintenance station is in a non-dust collection state, When the air inlet inside the dust collecting bin 3000 is closed, the internal airflow of the dust collecting bin 3000 does not communicate with the outside of the dust collecting bin 3000, and the drainage hole 2101 communicates with the outside of the dust collecting bin 3000. In this case, even if liquid, such as water from a mop cloth, enters the dust collecting bin 3000 through the air duct during the dust collection process, the drainage hole 2101 opens and the liquid flows out of the dust collecting bin 3000, thereby preventing damage to parts inside the dust collecting bin, especially damage to the fan.

[0064] In some embodiments, the dust collection bin 3000 further includes a drain valve 2103, which is disposed at an outlet position near the drain hole 2101 on the outside of the bottom of the dust collection bin 3000, and when the self-cleaning maintenance station is in a dust collection state, the drain valve 2103 closes the drain hole due to the action of negative pressure within the bin, so that the drain hole 2101 does not communicate with the outside of the dust collection bin 3000, and when the self-cleaning maintenance station is in a non-dust collection state, the drain valve 2103 opens under the action of gravity, so that the drain hole 2101 communicates with the outside of the dust collection bin 3000.

[0065] In some embodiments, the drain valve 2103 includes a fixed end 21031 and an elastic movable end 21032, the fixed end 21031 is fixedly attached to the outside of the bottom of the dust collecting bin 3000 by screwing, gluing, locking, etc., and the elastic movable end 21032 is provided at the outlet of the drain hole 2101 so as to be switchable between an open state and a closed state. The elastic movable end 21032 is made of a soft rubber plug material such as rubber or plastic. In a normal state, when the drain hole 2101 is in an open state and there is water at the bottom of the dust collecting bin 3000, the water is automatically discharged from the drain hole 2101. When the fan is operated, a negative pressure is formed in the dust collecting bin 3000, and the elastic movable end 21032 is automatically adsorbed to the outside of the drain hole to achieve sealing. After the fan is stopped, the elastic movable end 21032 automatically opens under the action of gravity, and when there is water in the dust collecting bin 3000, it is discharged from the drain hole 2101 again.

[0066] In some embodiments, a sidewall of the dust collection bin 3000 includes a water-blocking structure 2104, which is disposed at an edge of the inlet 2102 and configured to block liquid entering through the inlet. Specifically, the water-blocking structure 2104 includes a first baffle wall 21041 extending laterally along an edge of the inlet 2102 and a second baffle wall 21042 extending downward, the first baffle wall 21041 and the second baffle wall 21042 forming an air intake area. In some embodiments, the second baffle wall 21042 extends downward at least to a lower edge of the inlet 2102 and blocks liquid entering through the inlet 2102.

[0067] In some embodiments, the self-cleaning maintenance station body 2000 further includes a fan bin 2200, a fan passage 2210, and a fan 2220, the fan bin 2200 is disposed below the dust collection bin 3000 and is used to accommodate the fan 2220, the fan passage 2210 is configured to communicate the fan bin 2200 and the dust collection bin 3000 and provide suction force by the fan 2220, the fan 2220 is disposed within the fan bin 2200, can be turned on / off under the control of a control system, and is used to provide suction force required for dust collection. In some embodiments, the fan passage 2210 extends upwards along the bottom of the dust collection bin 3000 by a preset distance, and the fan passage 2210 protrudes from the bottom of the dust collection bin 3000, thereby avoiding liquid entering the dust collection bin 3000 from entering the fan bin 2200 and causing fan damage because it is not immediately discharged.

[0068] The self-cleaning maintenance station body provided in this embodiment includes a dust collection bin, and the dust collection bin includes a drainage hole provided at the bottom of the dust collection bin, and an air duct having one end communicating with the bottom plate and the other end communicating with the dust collection bin. When the self-cleaning maintenance station is in a dust collection state, the air duct communicates with the outside of the dust collection bin and the drainage hole does not communicate with the outside of the dust collection bin, so that a negative pressure state is ensured inside the dust collection bin, which is convenient for dust collection operations. When the self-cleaning maintenance station is in a non-dust collection state, the air duct does not communicate with the outside of the dust collection bin and the drainage hole communicates with the outside of the dust collection bin, so that water that has entered into the dust collection bin can be instantly discharged and damage to components inside the dust collection bin can be avoided.

[0069] In the related art, during the dust collection process of the fan in the self-cleaning maintenance station, the rotation of the fan causes large vibrations, which may damage the wall of the fan bin that comes into contact with it, and also causes large noise due to the vibrations.

[0070] Therefore, this embodiment provides a self-cleaning maintenance station, and a number of vibration damping devices are provided in the fan bin to reduce the vibration caused by the rotation of the fan, and similar structures have similar technical effects, some of which will not be repeated here. Specifically, as shown in Figures 1, 6 and 7, the self-cleaning maintenance station includes a self-cleaning maintenance station bottom plate 1000 and a self-cleaning maintenance station body 2000, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to the self-cleaning maintenance station body 2000, and the self-cleaning maintenance station body 2000 includes a fan bin 2200, a fan 2220 and a vibration damping device 2230. The fan bin 2200 is integrally installed inside the self-cleaning maintenance station body 2000, and includes an air inlet 2240 and an air outlet 2250. The air inlet 2240 communicates with the dust collecting bin 3000 through a fan passage 2210, and is used to suck in air by the rotation of the fan, suck out gas in the dust collecting bin 3000, and ensure negative pressure in the dust collecting bin 3000. The sucked gas enters the fan through the air inlet 2240 and is then discharged from the air outlet 2250. The fan 2220 is installed inside the fan bin 2200, and rotates forward or backward under the control of a control system. The vibration damping device 2230 is installed on at least a part of the outer surface of the fan 2220 and is used to reduce vibration of the fan 2220. The vibration damping device 2230 may be made of an elastic material such as rubber or plastic.

[0071] 8, in some embodiments, the vibration damping device 2230 includes a vibration damping cover 2231 assembled to at least a part of the top end of the fan 2220 to reduce the vibration of the fan, and the outer shape of the vibration damping cover 2231 is adapted to the fan top end structure, and the vibration damping cover 2231 is provided just covering the fan top end. Specifically, in some embodiments, the vibration damping cover 2231 has a vibration damping cover top surface 22311, and the vibration damping cover top surface 22311 includes a first opening 22312 adapted to the intake port 2240, and a protruding edge 22313 extending outwardly along the first opening 22312, assembled between the top end of the fan 2220 and the intake port 2240, and configured to reduce the vibration of the fan. In some embodiments, as the distance the protruding edge 22313 extends outward increases, the opening area of ​​the protruding edge gradually increases, and thus, after the vibration-damping cover 2231 is assembled to the fan top surface and assembled to the fan bin, the trumpet-shaped protruding edge 22313 is supported just around the fan bin inlet, sealing the inlet and reducing the impact of vibration and noise. In some embodiments, the vibration-damping cover top surface 22311 further includes at least one protrusion extending continuously around the circumferential direction of the first opening 22312, configured to reduce the vibration of the fan 2220 when abutted against the top inner wall of the fan bin 2200. In some embodiments, the vibration-damping cover top surface 22311 further includes a first protrusion 22314, a second protrusion 22315, and a third protrusion 22316 that extend continuously around the circumferential direction of the first opening 22312, and a groove 22317 is provided between the second protrusion 22315 and the third protrusion 22316, and extends continuously around the circumferential direction of the first opening 22312, and the first protrusion 22314, the second protrusion 22315, the third protrusion 22316, and the groove 22317 are extruded and deformed during the assembly process, thereby reducing the hard connection between the fan and the fan bin, and further reducing vibration damage. In some embodiments, the inside of the third protrusion 22316 has a plurality of discontinuous cavities, thereby further reducing the vibration of the fan.

[0072] In some embodiments, as shown in FIG. 8 , the vibration damping cover includes vibration damping cover sidewalls 22318 which extend downwardly along the vibration damping cover top surface 22311, and when the vibration damping cover 2231 is placed over the top surface of the fan, the vibration damping cover sidewalls 22318 encase the sides of the fan, wherein the vibration damping cover sidewalls 22318 include a plurality of spaced apart first protruding beams 22319 which are hollow and an outer wall of each first protruding beam 22319 abuts against a side wall of the fan bin 2200, further reducing vibration during operation of the fan.

[0073] In some embodiments, as shown in FIG. 9, the vibration damping device 2230 further includes a vibration damping pad 2232 assembled to at least a portion of a bottom end of the fan 2200 to reduce vibration of the fan 2200. In some embodiments, as shown in FIG. 10 , the vibration damping pad 2232 includes a second opening 22322 that fits the air outlet and a plurality of second protruding beams 22321 that extend laterally along the upper surface of the vibration damping pad 2232, where the second protruding beam 22321 is a hollow structure, and a side wall of the second protruding beam 22321 contacts the bottom of the fan 2200 to further reduce the vibration of the fan; after the vibration damping pad 2232 is assembled to the bottom end of the fan 2200, the air outlet structure of the bottom end of the fan enters the second opening 22322, and the bottom end of the fan is engaged with the assembly protrusion 22324 of the vibration damping pad 2232 by an interference fit, and the plane of the bottom end of the fan contacts the plurality of second protruding beams 22321 that extend laterally along the upper surface of the vibration damping pad 2232, and the hollow second protruding beams 22321 play a role in vibration reduction. In some embodiments, the vibration damping pad 2232 further includes a plurality of third protruding beams 22323 extending vertically along the inner wall of the second opening 22322, and the air outlet structure at the bottom end of the fan bin is in close contact with the plurality of third protruding beams 22323 after entering the second opening 22322, and the third protruding beams 22323 are hollow structures, further reducing the vibration of the fan.

[0074] According to the self-cleaning maintenance station provided by this embodiment, the self-cleaning maintenance station main body includes a fan arranged in a fan bin, and a vibration damping device assembled on at least a portion of the outer surface of the fan, and a plurality of vibration damping structures are provided in the vibration damping device, so that the impact of the vibration of the fan on the self-cleaning maintenance station can be reduced.

[0075] In the related art, the cleaning module at the bottom of the automatic cleaning device (such as the mop cloth bracket of the wet cleaning module) is usually a lifting structure, and does not stick to the bottom of the automatic cleaning device under natural gravity conditions. In addition, if the dust collection port of the automatic cleaning device is at the front of the cleaning groove, the cleaning module at the bottom of the automatic cleaning device will pass through the dust collection port when climbing up or leaving the pile, and when passing through the dust collection port, the cleaning module (especially the mop cloth bracket) is likely to get caught in the dust collection port, and the automatic cleaning device will not be able to climb up or leave the pile, especially when the automatic cleaning device climbs up the pile, the driving force for climbing up the pile backwards is usually not large, so it cannot climb up the pile smoothly. In addition, if the cleaning module is a wet cleaning module, the mop cloth that has just been washed is not completely dry, so when it rubs against the dust collection port, the water on the mop cloth will be sucked into the dust collection port and sucked into the dust collection box, leading to the damage of the fan.

[0076] Therefore, the embodiment of the present disclosure provides a self-cleaning maintenance station, and the base plate body is provided with a lifting structure, which can prevent the cleaning module from being scraped or stuck during the process of the automatic cleaning device climbing up and down the pile, and further improve the success rate of the automatic cleaning device climbing up and down the pile. Similar structures have similar technical effects, some of which will not be repeated here.

[0077] Specifically, an example of a self-cleaning maintenance station provided by an embodiment of the present disclosure is shown in Fig. 11. Fig. 12 is a diagram showing an example of a bottom plate of the self-cleaning maintenance station connected to a main body base from different angles, and Fig. 13 is a schematic diagram showing an example of the structure of the bottom plate of the self-cleaning maintenance station.

[0078] As shown in FIG. 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 .

[0079] The self-cleaning maintenance station body 2000 is configured to collect the dirt in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning maintenance station body 2000 may further be provided with components such as a dust collection bin 3000, a clean water tank 4000, and a dirty water tank 5000. A body base 6000 is integrally provided below the self-cleaning maintenance station body 2000. In some embodiments, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to the body base 6000 for convenient transportation.

[0080] In some embodiments, the body base 6000 below the self-cleaning maintenance station body 2000 includes a cleaning groove 6200 configured to replenish cleaning fluid to the wet cleaning module of the automatic cleaning device, and / or to accommodate dirt removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module, so as to make subsequent disposal of the dirt and wastewater easier. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100.

[0081] As shown in FIG. 11, the self-cleaning maintenance station base plate 1000 includes a base plate body 1100 and a lifting structure 1300 .

[0082] The base plate body 1100 is configured to support the automatic cleaning device when the automatic cleaning device returns to the base plate 1000 of the self-cleaning maintenance station. That is, the automatic cleaning device can move to the base plate 1000 of the self-cleaning maintenance station and be supported by the base plate body 1100. Specifically, in the process of the automatic cleaning device moving to the base plate 1000 of the self-cleaning maintenance station, the drive wheels of the automatic cleaning device run on the inclined surface of the base plate body 1100.

[0083] 11 and 13, the body base 6000 and the bottom plate body 1100 are sequentially arranged along a first direction X, and the bottom plate 1000 is connected to the body base 6000. Specifically, along the first direction X, the body base 6000 has a start end and a stop end, and the bottom plate body 1100 also has a start end and a stop end, and the stop end of the body base 6000 is abutted against the start end of the bottom plate body 1100. In some embodiments, the body base 6000 is detachably or non-detachably connected to the bottom plate body 1100, which is convenient for transportation.

[0084] The main body base 6000 and the bottom plate body 1100 form a continuous inclined surface at least along the first direction X, and the drive wheels of the automatic cleaning device can run relatively smoothly thereon. In some embodiments, the drive wheels of the automatic cleaning device are located on both sides of the bottom, and correspondingly, the main body base 6000 and the bottom plate body 1100 form a continuous inclined surface adapted to the position of the drive wheels, and the drive wheels run thereon. In some embodiments, the bottom plate body 1100 further includes a recess 1121 and a protrusion 1122, where the recess 1121 is located in the center of the bottom plate body 1100, and the protrusion 1122 is located on both sides of the recess. The angle between the upper surface of the recess 1121 and the horizontal plane is smaller than the angle between the upper surface of the protrusion 1122 and the horizontal plane.

[0085] In some embodiments, the angle between the top surface of the recess 1121 and the horizontal plane may be close to zero. The start ends of the protrusions 1122 abut against the stop ends of the main body base 6000 and have the same height, and the protrusions 1122 and the main body base 6000 form two continuous inclined surfaces that are adapted to the driving wheels. The recess 1121 is provided at the center of the base plate body 1100 to prevent the automatic cleaning device from being obstructed or scraped by the surface of the base plate body 1100 during the process of climbing up or leaving the pile.

[0086] Furthermore, the protrusion 1122 of the base plate body 1100 is provided with an anti-slip structure 1123 along the first direction X, and the anti-slip structure 1123 is provided at least at the start end and the stop end along the first direction of the base plate body 1100. The anti-slip structure 1123 may be a rib or groove of any shape, for example, a strip-shaped protrusion extending along the second direction Y, where the second direction Y is perpendicular to the first direction X. Providing the anti-slip structure 1123 on the protrusion 1122 can further help the automatic cleaning device to climb and leave the pile smoothly.

[0087] In some embodiments, the main body base 6000 has an upper surface called the first upper surface, and when the main body base 6000 is placed on a horizontal floor surface, the upper surface of the main body base 6000 is inclined at a predetermined inclination angle with respect to the horizontal plane, and the inclination corresponding to the predetermined inclination angle is called the first inclination. Similarly, the bottom plate body 1100 has an upper surface called the second upper surface, and when the bottom plate body 1100 is placed on a horizontal floor surface, the upper surface of the bottom plate body 1100 is inclined at a predetermined inclination angle with respect to the horizontal plane, and the inclination corresponding to the predetermined inclination angle is called the second inclination. In some embodiments, the bottom plate body 1100 includes a recessed portion 1121 and a protruding portion 1122, and the second inclination is the inclination of the upper surface of the protruding portion 1122 with respect to the horizontal plane. In some embodiments, the first inclination and the second inclination are related to each other such that the first inclination is greater than the second inclination. The power required by the automatic cleaning device immediately after climbing the pile is relatively small, and setting the second inclination small is beneficial for the automatic cleaning device to climb the pile.

[0088] 13, the dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and the dust in the dust box of the automatic cleaning device enters the dust collection station of the self-cleaning maintenance station body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, which is sealed after the dust collection port 6100 and the dust outlet of the automatic cleaning device are connected, and is used to prevent dust leakage. The dust collection port 6100 is located on the upper surface of the body base 6000, and is provided at approximately the edge position of the connection between the body base 6000 and the bottom plate body 1100.

[0089] 11 and 12 , the lifting structure 1300 is provided on the upper surface of the bottom plate body 1100, and is provided at approximately the edge position of the connection portion between the bottom plate body 1100 and the body base 6000. In some embodiments, the lifting structure 1300 is provided in the recessed portion 1121 of the bottom plate body 1100. The lifting structure 1300 is configured to press the cleaning module on the bottom surface of the automatic cleaning device during the process of the automatic cleaning device moving in the reverse direction (where the front side of the body faces the first direction X, which is the outside of the self-cleaning maintenance station body 2000) toward the self-cleaning maintenance station bottom plate 1000, so that the cleaning module moves toward the inside of the automatic cleaning device, for example, the cleaning module on the bottom surface of the automatic cleaning device is pushed into the automatic cleaning device.

[0090] During the process in which the automatic cleaning device moves in the reverse direction along the first direction X to the bottom plate 1000 of the self-cleaning maintenance station to connect the dust outlet of the automatic cleaning device with the dust collection port 6100 of the main body base 6000, if the lifting structure 1300 is not provided on the upper surface of the bottom plate main body 1100, the cleaning module of the automatic cleaning device (e.g., the mop cloth bracket of the wet cleaning module) may get caught on the dust collection port 6100 when passing through the dust collection port 6100, and the automatic cleaning device 100 may not be able to smoothly climb up or leave the pile.

[0091] A lifting structure 1300 is provided on the upper surface of the bottom plate body 1100. In the process of the automatic cleaning device moving in the reverse direction along the first direction X to the bottom plate 1000 of the self-cleaning maintenance station to connect the cleaning module of the automatic cleaning device with the cleaning groove of the self-cleaning maintenance station body 2000, the lifting structure 1300 is first abutted against at least a part of the frame of the cleaning module and the cleaning module is lifted by a certain height (e.g., 8 mm). At this time, the cleaning module is pressed by the lifting structure 1300, and the cleaning module moves toward the inside of the automatic cleaning device (e.g., is pushed into the automatic cleaning device by the lifting structure 1300). Then, when the automatic cleaning device continues to move in the reverse direction along the first direction X, the frame of the cleaning module passes above the dust collection port 6100 and gradually comes off the lifting structure 1300. In this process, even if the cleaning module is completely removed from the lifting structure 1300, part or all of the cleaning module is located above the dust collection port 6100, and the cleaning module can pass through gently in close contact with the dust collection port 6100. After the cleaning module completely passes through the dust collection port 6100, under the action of gravity, it gradually recovers to the state before being pressed by the lifting structure 1300, i.e., at least a part of the cleaning module protrudes in the direction away from the automatic cleaning device. In this way, the cleaning module descends by a certain height (e.g., 8 mm) under the action of gravity, and the cleaning module is connected with the cleaning groove.

[0092] By providing a lifting structure 1300 on the upper surface of the bottom plate body 1100, the dust collection port 6100 can be prevented from interfering with the cleaning module when the automatic cleaning device is climbing up or leaving the pile, and the success rate of the automatic cleaning device climbing up or leaving the pile can be improved.

[0093] In some embodiments, the lifting structure 1300 includes a wedge-shaped member 1310 and a roller 1320 .

[0094] The wedge-shaped member 1310 is provided on the upper surface of the bottom plate body 1100 and protrudes from the upper surface of the bottom plate body 1100 in a direction away from the upper surface. The wedge-shaped member 1310 includes a first inclined surface 1311, a first top surface 1313, and a second inclined surface 1312, which are arranged in sequence along a first direction X, and the first inclined surface 1311, the first top surface 1313, and the second inclined surface 1312 are abutted in sequence in the first direction X.

[0095] The acute angle between the first inclined surface 1311 and the upper surface of the bottom plate body 1100 on which it is located is defined as a first angle α, and the acute angle between the second inclined surface 1312 and the upper surface of the bottom plate body 1100 on which it is located is defined as a second angle β. In some embodiments, the first angle α is smaller than the second angle β, so that when the automatic cleaning device moves in the reverse direction along the first direction X to the bottom plate body 1100, the automatic cleaning device can be pressed gently and quickly descended. Specifically, in some embodiments, the first angle α may be in the range of 5 degrees to 25 degrees, for example, 5 degrees, 25 degrees, 10 degrees to 15 degrees, 10 degrees or 15 degrees, so that when the automatic cleaning device moves in the reverse direction along the first direction X to the bottom plate body 1100, the cleaning module on the bottom of the automatic cleaning device can be smoothly pressed by the lifting structure 1300. In some embodiments, the second angle β may be in the range of 75 degrees to 90 degrees, for example 75 degrees, 90 degrees, 80 degrees to 85 degrees, 80 degrees or 85 degrees, and the frame of the cleaning module quickly descends under the action of gravity after being released from the lifting structure 1300.

[0096] In addition, when the wedge-shaped member 1310 is provided in the recess 1121 of the bottom plate main body 1100, the first angle α is the angle between the first inclined surface 1311 and the upper surface of the recess 1121, and the second angle β is the angle between the second inclined surface 1312 and the upper surface of the recess 1121.When the wedge-shaped member 1310 is provided in the protrusion 1122 of the bottom plate main body 1100, the first angle α is the angle between the first inclined surface 1311 and the upper surface of the protrusion 1122, and the second angle β is the angle between the second inclined surface 1312 and the upper surface of the protrusion 1122.

[0097] The rollers 1320 are provided on the first top surface 1313 and are in rolling contact with the cleaning module when the cleaning module is pressed against the bottom surface of the automatic cleaning device and moves toward the inside of the automatic cleaning device. The rollers 1320 can reduce the frictional resistance between the frame of the cleaning module and the wedge-shaped member 1310, reduce wear between the components, and extend the service life of each component.

[0098] In some embodiments, a portion of the roller 1320 may be embedded within the wedge-shaped member 1310 to smoothly transition the sliding contact between the lifting structure 1300 and the frame of the cleaning module to a rolling contact. In some embodiments, the roller 1320 may be removably connected to said wedge-shaped member 1310 to facilitate replacement of the roller 1320.

[0099] In some embodiments, the number of lifting structures 1300 is at least two, and the at least two lifting structures 1300 are arranged opposite to each other in the second direction Y, and the second direction Y is perpendicular to the first direction X. In the process in which the automatic cleaning device moves toward the base plate body 1100 in the opposite direction along the first direction X, the at least two lifting structures 1300 are respectively abutted against the frame of the cleaning module, so that the cleaning module is uniformly lifted to a certain height. By providing two or more lifting structures 1300, the force applied to the cleaning module can be more distributed, and the cleaning module can be prevented from being biased in the second direction Y due to receiving uneven force.

[0100] In some embodiments, the number of the lifting structures 1300 is two, the two lifting structures 1300 are arranged opposite to each other in the second direction Y, and the two lifting structures 1300 are arranged substantially symmetrically with respect to the central axis of the base plate body 1100. The distance between the two lifting structures 1300 corresponds to the width of the dust collecting port 6100 in the second direction Y or is slightly larger than the width of the dust collecting port 6100 in the second direction Y, so as to avoid interfering with the main brush cover below the automatic cleaning device.

[0101] In some embodiments, the self-cleaning maintenance station base plate 1000 further includes a slope body 1400, which may be a slope and is provided on the surface of the base plate body 1100. Specifically, the slope body 1400 may be provided at the edge position of the connection part between the base plate body 1100 and the body base 6000, and is provided approximately in front of the dust collection port 6100 and at the central axis position of the base plate body 1100. In some embodiments, the number of the lifting structures 1300 is two, which are provided opposite to each other in the second direction Y, and the slope body 1400 is substantially located in the middle of the two lifting structures 1300. By providing the slope body 1400 on the surface of the base plate body 1100, it is possible to prevent the front end of the automatic cleaning device (especially the collision sensor provided at the front end) from contacting the edge of the dust collection port 6100 when the automatic cleaning device is climbing up the pile.

[0102] In some embodiments, the slope 1400 is provided in a recess 1121 of the base plate body 1100. In some embodiments, as shown in Fig. 13, the slope 1400 and the lifting structure 1300 are both provided in the recess 1121 of the base plate body 1100. By providing the recess 1121 at the center position of the base plate body 1100 and providing the slope 1400 and the lifting structure 1300 in the recess 1121, it is possible to avoid the automatic cleaning device being obstructed by or rubbed against the surface of the base plate body 1100 during the process of climbing up or leaving the pile.

[0103] In some embodiments, the lifting structure 1300 is provided in the recess 1121 of the base plate body 1100, and the height of the lifting structure 1300 is higher than the protrusion 1122, effectively pressing the cleaning module on the bottom surface of the automatic cleaning device, thereby allowing the cleaning module to move a large distance toward the interior of the automatic cleaning device.

[0104] In some embodiments, the slope 1400 is provided in the recess 1121 of the base plate body 1100, and the height of the slope 1400 is substantially the same as the protrusion 1122. If the height of the slope 1400 is too low, it cannot prevent the automatic cleaning device from touching the edge of the dust collection port 6100 when climbing up the pile, and if the height of the slope 1400 is too high, it will interfere with the automatic cleaning device when it is climbing up or leaving the pile.

[0105] In some embodiments, the lifting structure 1300 has a preset distance from the stop end of the base plate body 1100, so that when the automatic cleaning device enters the bottom plate 1000 of the self-cleaning maintenance station backward, the lifting structure 1300 does not contact the cleaning module before the driving wheel of the automatic cleaning device enters the stop end of the base plate body 1100. This is because, before the driving wheel of the automatic cleaning device contacts the anti-slip structure 1123 at the starting end, the retreating force of the automatic cleaning device is relatively small, and at this time, if the lifting structure 1300 contacts the cleaning module (such as a mop cloth bracket), it may hinder the automatic cleaning device from climbing the pile, and even lead to failure of the pile climbing. Correspondingly, when the driving wheel of the automatic cleaning device enters the stop end of the bottom plate body 1100, the lifting structure 1300 may hit the cleaning module, and at this time the automatic cleaning device has already stepped on the anti-slip structure 1123, and the automatic cleaning device can smoothly climb up and off the pile with the help of the anti-slip structure 1123.

[0106] The present disclosure further provides a self-cleaning system comprising an automatic cleaning device and a self-cleaning maintenance station according to the above embodiment.

[0107] The self-cleaning maintenance station and self-cleaning system provided by the embodiments of the present disclosure are provided with a lifting structure on the bottom plate body, which can avoid the phenomenon of the cleaning module being scraped or stuck when the automatic cleaning device is climbing up or off the pile, and thus improve the success rate of the automatic cleaning device climbing up or off the pile.

[0108] In the related art, the structure of the air duct of the self-cleaning maintenance station is usually complicated, which occupies more physical space and makes the self-cleaning maintenance station look bulky. In addition, the complicated air duct structure also reduces the dust collection effect to a certain extent, and it is difficult to suck all the garbage in the dust box into the dust collection chamber of the self-cleaning maintenance station.

[0109] Therefore, an embodiment of the present disclosure provides a self-cleaning maintenance station, optimizes the air duct structure inside the self-cleaning maintenance station, and shortens the path of the air duct, making the air duct of the self-cleaning maintenance station smoother and more compact in structure, thereby further improving the dust collection efficiency of the automatic cleaning device.

[0110] Specifically, an example of a self-cleaning maintenance station provided by an embodiment of the present disclosure is shown in Fig. 14. Fig. 14 is a schematic diagram showing an example of the overall structure of a dust box combined with a self-cleaning maintenance station, and Fig. 15 and Fig. 16 are diagrams showing the air duct structure of the self-cleaning maintenance station and the direction of airflow in the air duct in the dust collection state.

[0111] 14, the self-cleaning maintenance station provided in this embodiment includes a self-cleaning maintenance station bottom plate 1000 and a self-cleaning maintenance station body 2000. Here, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to the self-cleaning maintenance station body 2000, specifically, the self-cleaning maintenance station bottom plate 1000 is detachably or non-detachably connected to a body base 6000 at the bottom of the self-cleaning maintenance station body 2000. The detachable connection method can facilitate transportation and maintenance.

[0112] The self-cleaning maintenance station body 2000 is configured to collect the dirt in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning maintenance station body 2000 may be provided with components such as a dust collection bin 3000, a clean water tank 4000, and a dirty water tank 5000 arranged side by side. Specifically, as shown in FIG. 2, the self-cleaning maintenance station body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 is opened upward and forward and arranged at the top of the self-cleaning maintenance station body 2000, and the water storage chamber may further include a clean water bin for accommodating the clean water tank 4000 and a dirty water bin for accommodating the dirty water tank 5000. The dust collection chamber 2100 is opened upward and forward and arranged at the top end of the self-cleaning maintenance station body 2000 alongside the water storage chamber 2700, and the dust collection chamber 2100 constitutes a dust collection bin 3000 for accommodating the dust collection cover 2800. The water storage chamber 2700 and the dust collection chamber 2100 are designed to face upward and forward, which makes it convenient to attach and detach the dirty water tank 5000, the purified water tank 4000 and the dust collection cover 2800.

[0113] There is a body base 6000 below the self-cleaning maintenance station body 2000. In some embodiments, the body base 6000 is integrally provided below the self-cleaning maintenance station body 2000. The body base 6000 is further abutted against the bottom plate 1000 of the self-cleaning maintenance station, specifically, the bottom plate 1000 of the self-cleaning maintenance station and the body base 6000 are sequentially provided along a second direction, which is opposite to the arrow of the front-rear axis X.

[0114] As shown in FIG. 14 , the dust collection port 6100 is provided on the main body base 6000 and is located at approximately the edge position of the connection between the main body base 6000 and the bottom plate 1000 of the self-cleaning maintenance station. The dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and the dust in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning maintenance station main body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, which is used to seal the dust collection port 6100 and the dust outlet of the automatic cleaning device after they are connected to prevent dust leakage. The dust collection port 6100 extends substantially along a first direction, which is opposite to the arrow of the transverse axis Y, and which is substantially perpendicular to the second direction. The first direction is also the longitudinal direction of the dust collection port 6100, and the extension distance of the dust collection port 6100 in the first direction is a length L 1 The dust collection port 6100 extends along a first direction and also extends along a second direction, the second direction being the width direction of the dust collection port 6100, and the extension distance of the dust collection port 6100 in the second direction is a width W 1 and further, the length L 1 and width W 1 Between 1 >W 1 There is a relationship as follows.

[0115] In some embodiments, the body base 6000 further includes a cleaning groove 6200, which is configured to clean the cleaning member of the automatic cleaning device, for example, to replenish cleaning liquid in the wet cleaning module of the automatic cleaning device, and / or to accommodate dirt removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module, and facilitate subsequent treatment of the dirt and wastewater. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100. The cleaning groove 6200 extends to the lower part of the self-cleaning maintenance station body 2000 along the second direction, and a side wall may be formed between the self-cleaning maintenance station body 2000 and the cleaning groove 6200.

[0116] 15 and 16, the self-cleaning maintenance station main body 2000 further includes an air duct 2500, one end of which communicates with the dust collection port 6100 of the main body base 6000, and the other end of the air duct 2500 communicates with the dust collection chamber 2100. When the self-cleaning maintenance station is in a dust collection state, a sufficient negative pressure is formed in the dust collection bin 3000, and the dust in the dust box 300 is sucked into the dust collection bag through the dust collection port 6100 and the air duct 2500. The air duct 2500 is further divided into a main body air duct 2510 and a base air duct 2520 according to its location. The base air duct 2520 is substantially disposed at the position indicated by the dashed frame in the lower right corner of FIG. 15, and the main body air duct 2510 is substantially disposed at the position indicated by the dashed frame in the upper right corner of FIG. 15. In Figures 15 and 16, solid arrows indicate the trajectory of dust movement in the base air duct 2520 and main body air duct 2510 driven by the airflow.

[0117] The base air duct 2520 is located inside the main body base 6000, and the base air duct 2520 is substantially an L-shaped structure, with one end of the base air duct 2520 communicating with the longitudinal direction of the dust collection port 6100 and the other end communicating with the main body air duct 2510 on the side wall of the self-cleaning maintenance station main body 2000. Specifically, the base air duct 2520 communicates with the longitudinal direction of the dust collection port 6100 and extends to approximately the edge position of the main body base 6000 along a first direction, and then extends to the main body air duct 2510 along a second direction. In some embodiments, one end of the base air duct 2520 in the longitudinal direction of the dust collection port 6100 communicates with the dust collection port 6100, so that the airflow and the dust driven thereby directly flows out from one end of the longitudinal direction of the dust collection port 6100 and proceeds along an approximately straight line, reducing the resistance of the airflow when it flows out of the dust collection port 6100. In some embodiments, the position where the base air duct 2520 extends along the second direction is between the edge of the cleaning groove 6200 and the edge of the main body base 6000, which can fully utilize the limited space of the main body base 6000 and reduce the overall size of the product. In some embodiments, the width of the base air duct 2520 may be slightly smaller than the width of the dust collection port 6100, and the width of the air duct may be the maximum value of the cross section of the air duct, for example, when the cross section of the air duct is circular or close to circular, the width of the air duct is the diameter of the circle or the length of the major axis of an ellipse, and by appropriately reducing the width of the base air duct 2520, the air flow velocity in the base air duct 2520 can be increased, making it easier for the dust in the dust box 300 to pass through the base air duct 2520, avoiding clogging of the base air duct 2520, and improving the dust collection effect. In some embodiments, the base air duct 2520 extends along a first direction and extends along a second direction with the bends smoothly connecting in an arc, and the first and second directions are approximately vertical, but the bends in the base air duct 2520 in the first and second directions do not turn at right angles, but are replaced with arc sections tangent to two sides of the corners instead of the original right angles, making the airflow passing through the base air duct 2520 gentler and preventing abrupt changes in flow rate.Similarly, the base air duct 2520 extends along the second direction, and the bent portion formed by extending upward from the main body air duct 2510 may also be smoothly connected in an arc shape.

[0118] The main body air duct 2510 is at least provided on a side wall of the self-cleaning maintenance station body 2000, one end of the main body air duct 2510 communicates with the base air duct 2520 and the other end leads to the dust collection chamber 2100, and the main body air duct 2510 communicates with the base air duct 2520 and the dust collection chamber 2100. Specifically, the main body air duct 2510 extends upward along the side wall of the self-cleaning maintenance station body 2000 to the dust collection bin 3000, and the side wall to which the main body air duct 2510 extends may be formed by the side edge of the cleaning groove 6200 and the side edge of the self-cleaning maintenance station body 2000. The above design of the main body air duct 2510 can fully utilize the vacant space between the self-cleaning maintenance station body 2000 and the cleaning groove 6200, making the structure more compact. In some embodiments, the width of the main air duct 2510 is larger than the width of the base air duct 2520, and by appropriately adjusting the width relationship between the main air duct 2510 and the base air duct 2520, the flow rate of the airflow in the base air duct 2520 can be increased, so that the dust in the dust box 300 can easily pass through the base air duct 2520, thereby avoiding clogging of the base air duct 2520 and improving the dust collection effect.

[0119] In some embodiments, the main air duct 2510 and the base air duct 2520 are two independent structures that communicate with each other through an interface, and the separate structures can facilitate maintenance of the ducts, especially when the ducts are clogged; in some embodiments, the main air duct 2510 and the base air duct 2520 are an integral structure, and the integral structure can effectively avoid airflow leakage in the air ducts.

[0120] The present disclosure further provides a self-cleaning system comprising an automatic cleaning device and a self-cleaning maintenance station in the above embodiment.

[0121] 14 and 16, the figures show a dust box 300 included in the automatic cleaning device, the dust box 300 having a dust inlet 310 and an air intake 320, where the air intake 320 is provided on a side wall of the dust box 300 in a first extension direction toward the base air duct 2520, the dust inlet 310 is provided on a side wall of the dust box 300 toward the self-cleaning maintenance station main body 2000, and the dust inlet 310 is connected to a dust outlet of the automatic cleaning device.

[0122] Under the dust collection state, the air inlet 320 of the dust box 300 is opened, and the first fan in the self-cleaning maintenance station starts to work, sucking out the gas in the dust collection chamber 2100 and the air duct 2500, and the air pressure in the dust collection chamber 2100 and the air duct 2500 decreases, and the airflow forms a U-shaped passage between the air inlet 320 of the dust box 300, the dust inlet 310, the dust outlet of the automatic cleaning device, the dust collection port 6100 of the self-cleaning maintenance station and the air duct 2500, and the airflow lifts up the garbage in the dust box 300, and the garbage in the dust box 300 is lifted by the airflow and finally sucked into the dust collection chamber 2100. The U-shaped passage is the optimal inflow and outflow passage of the airflow, and the design of the U-shaped passage makes the airflow smoother, making it easier for the garbage in the dust box to be discharged from the dust box, and then through the air duct into the dust collection bin.

[0123] According to the self-cleaning maintenance station and self-cleaning system provided by the embodiments of the present disclosure, by optimizing the air duct structure inside the self-cleaning maintenance station, the path of the air duct can be made smaller, the air duct of the self-cleaning maintenance station can be made smoother, the structure is compact, and the dust collection efficiency of the automatic cleaning device can be further improved.

[0124] Finally, please note that each embodiment in this specification will be described gradually, with each embodiment focusing on the differences from other embodiments, and that identical or similar parts between each embodiment may be referenced to each other.
