[0012] 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.

[0013] 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. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural, and "plurality" generally includes at least two, unless the context clearly indicates otherwise.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0018] In the related art, the structure of the self-cleaning dust collecting sheet is usually complicated, the water tank is arranged in a complex hood cover of the self-cleaning dust collecting sheet, which makes it difficult to take out and use, and the water tank connection port is formed at the bottom of the water tank, which makes it easy for the water in the water tank to overflow and highly likely to damage the parts in the self-cleaning dust collecting sheet, and furthermore, the air duct of the self-cleaning dust collecting sheet is also too complicated, which makes it difficult for dust to enter the dust box into the dust collecting bin.

[0019] Therefore, the embodiment of the present disclosure provides a self-cleaning dust collecting sheet, and the water tank and the dust collecting cover are exposed to the outside of the self-cleaning dust collecting sheet body, which makes it easy for users to install and use it. At the same time, the water inlet (i.e., the water inlet and outlet) is provided at the top of the self-cleaning dust collecting sheet body, which makes it difficult for water to overflow from the water tank, and the air duct is provided directly on the side wall of the self-cleaning dust collecting sheet body, which shortens the air duct path and improves dust collection efficiency. Specifically, an example of a self-cleaning dust collecting sheet provided by the embodiment of the present disclosure is shown. Figure 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collecting sheet, and Figure 2 is a schematic diagram illustrating the structure of the self-cleaning dust collecting sheet body after removing the dirty water tank, clean water tank, and dust collecting cover of the present disclosure.

[0020] In order to more clearly describe the behavior of the self-cleaning dust collecting sheet, the following directions are defined: the self-cleaning dust collecting sheet is defined by three mutually perpendicular axes: the transverse axis Y, the front-rear axis X and the central vertical axis Z. The direction opposite to the arrow along the front-rear axis X, i.e. the direction in which the automatic cleaning device enters the self-cleaning dust collecting sheet, is defined as "rear", and the direction of the arrow along the front-rear axis X, i.e. the direction in which the automatic cleaning device leaves the self-cleaning dust collecting sheet, is defined as "forward". The transverse axis Y is substantially along the width of the body of the self-cleaning dust collecting sheet. The vertical axis Z is a direction extending upwards along the bottom surface of the self-cleaning dust collecting sheet.

[0021] As shown in FIG. 1 , the direction in which the bottom plate of the self-cleaning dust collecting sheet protrudes from the self-cleaning dust collecting sheet body is the front, the direction toward the rear wall of the self-cleaning dust collecting sheet body is the rear, the dust collecting bin is on the left side of the self-cleaning dust collecting sheet, the clean water tank 4000 is on the right side of the dust collecting bin 3000, and the dirty water tank 5000 is on the right side of the clean water tank 4000.

[0022] As shown in FIG. 1, the self-cleaning dust collecting sheet provided in this embodiment includes a bottom plate 1000 of the self-cleaning dust collecting sheet, a main body 2000 of the self-cleaning dust collecting sheet, and a dust collecting bin 3000, a clean water tank 4000, and a dirty water tank 5000 arranged next to the main body 2000 of the self-cleaning dust collecting sheet. The dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collecting sheet main body 2000. As shown in FIG. 2, the self-cleaning dust collecting sheet main body 2000 includes a water storage chamber 2700, a dust collecting chamber 2100 and an air duct 2500. The water storage chamber 2700 is open upward and forward and is located at the top of the self-cleaning dust collecting sheet main body 2000. The water storage chamber includes a clean water chamber 2400 for accommodating a clean water tank 4000 and a and a dirty water chamber 2300 for accommodating a dirty water tank 5000. The dust collection chamber 2100 is open upward and forward and is located at the top end of the self-cleaning dust collection sheet main body 2000 alongside the water storage chamber. The dust collection chamber 2100 forms a dust collection bin 3000 for accommodating a dust collection cover 2800. The water storage chamber 2700 and the dust collection chamber 2100 are designed to open upward and forward, which makes it easy to attach and detach the dirty water tank 5000, the clean water tank 4000 and the dust collection cover 2800. Usually, the dirty water tank 5000, the clean water tank 4000 and the dust collection cover 2800 are all assembled to the self-cleaning dust collection sheet main body 2000 from the front and upper direction. This structural design is in line with the usage habits of users. Furthermore, the design opening upward and forward makes it convenient for daily maintenance of the components in the water storage chamber 2700 and the dust collection chamber 2100.

[0023] The self-cleaning dust collecting sheet body 2000 further includes an air duct 2500, at least a part of which is provided on the side wall of the self-cleaning dust collecting sheet body 2000, and the air duct 2500 connects the body base 6000 at the bottom of the self-cleaning dust collecting sheet body 2000 and the dust collecting chamber 2100, and during the dust collecting process, the dust in the dust box enters the air duct 2500 through the dust collecting port of the body base 6000 and enters the dust collecting chamber 2100 through the air duct 2500. The self-cleaning dust collecting sheet body 2000 is configured to collect the dust in the dust box of the automatic cleaning device. The self-cleaning dust collecting sheet main body base 6000 has a dust collecting port 6100, which is 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 collecting bin 3000 of the self-cleaning dust collecting sheet main body 2000 through the dust collecting port 6100. A sealing rubber gasket is further provided around the dust collecting port 6100, which is used to connect and seal the dust collecting port 6100 and the dust outlet of the automatic cleaning device, ensuring the dust collecting effect and preventing dust leakage.

[0024] 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, the front wall and a number of side walls of the self-cleaning dust collecting sheet body 2000, the rear wall and the front wall of the water storage chamber 2700 and the dust collection chamber 2100 are respectively coplanar and coplanar with one of the side walls, wherein the height of the rear wall of the self-cleaning dust collecting sheet body 2000 is higher than the height of the front wall of the self-cleaning dust collecting sheet body 2000, the side walls of the self-cleaning dust collecting sheet body 2000 are connected to the rear wall and the front wall, and the end surfaces of the side walls of the self-cleaning dust collecting sheet body 2000 have 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 clean 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 clean water tank 4000 and the dust collection cover 2800 attached to the water storage chamber 2700 and the dust collection chamber 2100.

[0025] The water storage chamber 2700 is used to accommodate the dirty water tank 5000 and the clean water tank 4000, and the water storage chamber 2700 includes a boss 2600 that abuts against the rear wall of the water storage chamber 2700 and extends upward at the bottom of the water storage chamber 2700 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 clean 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 clean water chamber 2400 for accommodating the clean water tank 4000.

[0026] 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 clean water tank connection port 2630 is provided corresponding to the top end of the boss 2600 at the assembly position of the clean water tank 4000, and the clean water in the clean water tank 4000 flows through the clean 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 dirty water tank connection port 2620, and the clean water tank connection port 2630 are located at the top end of the boss 2600 to prevent the water in the clean water tank or the dirty water tank from overflowing into the clean water chamber or the dirty water chamber during the process of replacing the clean water tank or the dirty water tank. The top end sealed connection of the air pump port 2610, the dirty water tank connection port 2620, and the clean water tank connection port 2630 with the dirty water tank 5000 and the clean water tank 4000 is more convenient in operation than the bottom end connection of the clean water chamber or the dirty water chamber.

[0027] The self-cleaning dust collecting sheet further includes a dirty water tank 5000 and a clean water tank 4000 arranged next to the water storage chamber, and a dust collecting cover 2800 arranged next to the dust collecting chamber 2100, and the top surfaces of the dirty water tank, the clean water tank and the dust collecting cover are substantially flush with each other, and the front surfaces are substantially flush with each other. After the dirty water tank 5000, the clean water tank 4000 and the dust collecting cover 2800 are assembled to the self-cleaning dust collecting sheet main body 2000, a flat arrangement structure is formed, which on the one hand makes it easy to attach and detach and use, and on the other hand has a flat outer shape, which improves the aesthetics and improves the user experience.

[0028] When the self-cleaning dust collecting sheet is used for a long time, the soft rubber protrusion openings are inevitably contaminated by dirty water from 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.

[0029] When the wastewater tank 5000 and the clean water tank 4000 are assembled in the water storage chamber, the top surfaces of the wastewater tank and the clean water tank are higher than the rear wall of the self-cleaning dust collecting sheet main body, and most of the tank bodies of the wastewater tank and the clean water tank are located outside the water storage chamber, and when the dust collecting cover 2800 is assembled in the dust collecting chamber 2100, the top surface of the dust collecting cover is higher than the rear wall of the self-cleaning dust collecting sheet main body, and most of the dust collecting cover is located outside the dust collecting chamber. According to the above design, the amount of material used for the self-cleaning dust collecting sheet body is reduced, and the tops of the sewage tank, clean water tank and dust collecting cover are exposed to the outside of the dust collecting chamber, so that people can easily lift the handles provided on the tops of the sewage tank, clean water tank and dust collecting cover, and easily operate the sewage tank, clean water tank and dust collecting chamber, and the technical effect of an aesthetic design is also obtained; at the same time, the top of the self-cleaning dust collecting sheet body is designed with a low front wall and a high rear wall, and the front upper positions of the sewage tank, clean water tank and dust collecting cover are also exposed to the outside of the dust collecting chamber, so that people can easily observe the water level in the transparent sewage tank and clean water tank and the situation in the dust collecting chamber, and can timely perform the corresponding operations of the sewage tank, clean water tank and dust collecting chamber.

[0030] 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, and the sealed connection completely seals the inside of the dust collection bin, contributing to improved dust collection efficiency.

[0031] A cleaning chamber that is open forward is formed between the lower part of the self-cleaning dust collecting sheet main body 2000 and the main body base 6000, and the cleaning chamber is used to accommodate the automatic cleaning device when the automatic cleaning device returns to the self-cleaning dust collecting sheet for maintenance operation. A cleaning groove is provided at the bottom of the self-cleaning dust collecting sheet main body, and after the automatic cleaning device is accommodated in the cleaning chamber, the cleaning member of the automatic cleaning device is cleaned through the cleaning groove.

[0032] After the automatic cleaning device, for example a sweeping robot, returns to the self-cleaning dust collecting sheet after completing cleaning, the automatic cleaning device moves along the inclined surface of the bottom plate 1000 of the self-cleaning dust collecting sheet to the main body base 6000, 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 dust collecting sheet main body 2000.

[0033] 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. An air inlet of the dust collection duct is a dust collection port, and an air outlet of the dust collection duct communicates with the dust collection chamber 2100 via an air duct 2500.

[0034] 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 dust collection sheet body, thereby achieving the technical effect of the automatic cleaning device collecting dust in one go after multiple cleanings, 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.

[0035] In the related art, the structure of the self-cleaning dust collecting sheet is usually complex, the water tank is located in a complex hood cover of the self-cleaning dust collecting sheet, which makes it difficult to remove and use, and the water tank connection port is formed at the bottom of the water tank, which makes it easy for the water in the water tank to overflow and highly likely to damage parts in the self-cleaning dust collecting sheet.

[0036] Therefore, the embodiment of the present disclosure provides a self-cleaning dust collecting sheet, and by exposing at least a part of the water tank to the outside of the self-cleaning dust collecting sheet body, it is easy for the user to attach and detach, 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 described here.

[0037] Specifically, an example of a self-cleaning dust collecting sheet 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 main body of the self-cleaning dust collecting sheet after removing the dirty water tank, clean water tank, and dust collecting cover of the present disclosure. Figs. 3 to 5 are schematic diagrams showing the water storage tank of the self-cleaning dust collecting sheet of the present disclosure from different viewing angles.

[0038] 1, the self-cleaning dust collecting sheet provided in this embodiment includes a bottom plate 1000 of the self-cleaning dust collecting sheet, a main body 2000 of the self-cleaning dust collecting sheet, and a water tank 7000. Here, in order to facilitate transportation and maintenance of the bottom plate 1000 of the self-cleaning dust collecting sheet and the main body 2000 of the self-cleaning dust collecting sheet, the bottom plate 1000 of the self-cleaning dust collecting sheet is detachably or non-detachably connected to the main body 2000 of the self-cleaning dust collecting sheet, and the water tank 7000 is assembled to the top end of the main body 2000 of the self-cleaning dust collecting sheet.

[0039] As shown in FIG. 2, the self-cleaning dust collecting sheet body 2000 includes a water storage chamber 2700, which opens upward and forward and is provided at the top of the self-cleaning dust collecting sheet body 2000. The water storage chamber 2700 is configured to accommodate a water storage tank 7000. The water storage tank 7000 may be a clean water tank 4000 or a dirty water tank 5000. The water storage tank 7000 may be multiple. In some embodiments, the self-cleaning dust collecting sheet body 2000 includes two water storage tanks 7000, which are respectively a clean water tank 4000 and a dirty water tank 5000, and correspondingly, the water storage chamber includes a clean water chamber 2400 for accommodating the clean water tank 4000, and a dirty water chamber 2300 for accommodating the dirty water tank 5000. The water chamber 2700 is designed to open upward and forward, and the water tank 7000 is assembled to the self-cleaning dust collecting sheet body 2000 from the front and upward direction, 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 easy to perform daily maintenance on the components in the water chamber 2700.

[0040] The water storage chamber 2700 is surrounded by the rear wall, front wall and multiple side walls of the self-cleaning dust collecting sheet body 2000, where the height of the rear wall of the self-cleaning dust collecting sheet body 2000 is higher than the height of the front wall of the self-cleaning dust collecting sheet body 2000, the side walls of the self-cleaning dust collecting sheet body 2000 connect the rear wall and the front wall, and the end faces of the side walls of the self-cleaning dust collecting sheet 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.

[0041] The water chamber 2700 further includes a rear wall in contact with the water chamber 2700, and a boss 2600 extending 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 the water tank protrusion 7220 of the water tank 7000.

[0042] 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.

[0043] In some embodiments, the soft rubber protrusion opening includes an air pump connection port 2610 and a wastewater tank connection port 2620, and is located corresponding to the top end of the boss 2600 at the assembly position of the wastewater tank 5000. The air pump sucks out the air in the wastewater tank 5000 through the air pump connection 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.

[0044] In some embodiments, the soft rubber protrusion opening further includes a clean water tank connection port 2630 provided corresponding to the top end of the boss 2600 at the assembly position of the clean water tank 4000, and the clean water in the clean water tank 4000 flows into the squeegee member in the cleaning groove through the clean water tank connection port 2630 under the action of the peristaltic pump to clean the cleaning head of the automatic cleaning device.

[0045] The air pump port 2610, the dirty water tank connection port 2620, and the clean water tank connection port 2630 are provided at the top end of the boss 2600, to prevent the water in the clean water tank or the dirty water tank from overflowing from the water tank and flowing into the clean water chamber or the dirty water chamber during the process of replacing the clean water tank or the dirty water tank. The air pump port 2610, the dirty water tank connection port 2620, and the clean water tank connection port 2630 are connected at the top end with the dirty water tank 5000 and the clean water tank 4000, which is more convenient in operation than the connection at the bottom end of the clean water chamber or the dirty water chamber.

[0046] When the self-cleaning dust collecting sheet is used for a long time, the soft rubber protrusion openings are inevitably contaminated by dirty water when the cleaning member is washed, 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, so that the arm or cleaning tool can contact the soft rubber protrusion openings from any angle, and the user can easily clean the dirt accumulated around the soft rubber protrusion openings.

[0047] In some embodiments, the top of the boss 2600 may be provided with a plurality of soft rubber protrusion points 2640, which are correspondingly adapted to the pits 7221 provided on the underside of the water tank protrusion 7220 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 number of the soft rubber protrusion points 2640 is four, which are distributed approximately evenly on the top of the boss 2600. Through the cooperation and restriction of the soft rubber protruding points 2640 and the pits 7221, the position of the water tank 7000 in the water chamber 2700 can be made more accurate, and displacement of the water tank 7000 can be avoided.

[0048] The water chamber 2700 may further include a vertically extending partition plate 2710, which divides the water 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 clean water chamber 2400 for accommodating a clean 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 limiting protrusion (not shown) is provided on each side of the partition plate 2710, and at least one position-limiting recess 7120 that is adapted to the limiting protrusion is provided on the side walls of the waste water tank and the clean water tank facing the partition plate 2710, and after the waste water tank and the clean water tank are assembled into the waste water chamber and the clean water chamber, the limiting protrusion is restricted in cooperation with the position-limiting recess.

[0049] The water tank 7000 is detachably assembled on the top end of the self-cleaning dust collecting sheet 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 liquid level in the water tank 7000.

[0050] In some embodiments, when the water tank 7000 is assembled to the water chamber 2700, the top surface of the water tank 7000 may be higher than the rear wall of the water chamber 2700, and most of the tank body of the water tank 7000 may be located outside the water chamber 2700. The above design further optimizes the installation and removal of the water tank 7000, which is convenient for users to daily replace the liquid in the water tank 7000, and reduces the material usage of the self-cleaning dust collecting sheet body 2000. In addition, the top of the self-cleaning dust collecting sheet body 2000 is designed with a low front wall and a high rear wall, and the front and upper position of the water chamber 2700 is also exposed to the outside of the cavity, so that the user can easily observe the water level situation in the transparent water chamber 2700 and perform corresponding operations on the water chamber 2700.

[0051] The water tank 7000 may be a clean water tank 4000 or a dirty water tank 5000. The water tank 7000 may be multiple. In some embodiments, the self-cleaning dust collecting sheet main body 2000 includes two water tanks 7000, which are a clean water tank 4000 and a dirty water tank 5000, respectively. The dirty water tank 5000 and the clean 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 clean water tank 4000 are substantially flush, and the front surfaces are substantially flush. After the dirty water tank 5000 and the clean water tank 4000 are assembled on the self-cleaning dust collecting sheet main body 2000, they are formed into a flat arrangement structure, which on the one hand makes it easy to attach and detach and use, and on the other hand has a flat outer shape, which improves aesthetics and improves user experience.

[0052] 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 clean water tank 4000, the opening is a clean water port, and if the water tank 7000 is a dirty water tank 5000, the opening is a dirty water 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.

[0053] 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.

[0054] 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, which is limited in cooperation with a protrusion in the water chamber 2700. 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 to exceed a maximum water level line 7111, and a second recess 7120 extending upward along the bottom of the water tank housing to exceed a preset height, and the height of the second recess 7120 is not limited. Here, the first recess 7110 is limited in cooperation with at least a part of the boss 2600, 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 protruding point 2640 provided on the boss 2600, and the second recess 7120 is limited in cooperation with the protrusion on the inner side wall of the water chamber 2700. The recess provided on the water tank receiving part 7100 achieves the overall restriction of the water tank 7000, and the water tank 7000 is relatively accurately provided at the corresponding position of the water chamber 2700, thereby preventing the water tank 7000 from being displaced.

[0055] 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.

[0056] 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. When the water tank 7000 is a clean water tank 4000, a clean water port is 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 dirty water port or clean water port provided on the underside of the water tank protrusion 7140 is connected to the soft rubber protrusion opening at the top of the boss 2600.

[0057] In some embodiments, the water storage tank 7000 is a dirty water tank 5000, and an air pump connector is further provided on the underside of the water tank protrusion 7140, and the air pump connector is connected to the air pump connection port 2610 on the top of the boss 2600. After the air pump connection port 2610 is connected to the air pump connector, 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 connection port 2610 and the air pump connector, 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 cleaning groove is sucked into the dirty water tank 5000 through the dirty water pipe and the dirty water tank connection port 2620.

[0058] A plurality of pits 7221 are further provided on the underside of the water tank protrusion 7140. When the water tank 7000 is assembled into 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 on the top of the boss 2600 to achieve the restriction of the water tank 7000. Through the cooperation and restriction between the soft rubber protrusion point 2640 and the pits 7221, the position of the water tank 7000 in the water chamber 2700 can be made more accurate, and the displacement of the water tank 7000 can be avoided.

[0059] 5, in some embodiments, the water tank 7000 is the clean water tank 4000, where the water tank 7000 further includes a water pipe bracket 7300 and a water pipe 7400. The water pipe bracket 7300 is provided on a protruding structure 7900 in the clean water tank 4000, 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 clean water tank 4000. The water pipe 7400 extends from the water pipe bracket 7300 to the bottom of the clean water tank 4000, and the liquid flows to the outside of the clean 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 clean water tank 4000, the water pipe outlet is located at the water pipe bracket 7300, and the water pipe outlet is connected to the clean water port of the clean water tank 4000.

[0060] In some embodiments, the water tank 7000 is the clean 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 clean 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 a fixed axis of the float base 7500, and is configured to detect the water level in the tank.

[0061] In some embodiments, the water tank 7000 is the clean 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.

[0062] 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.

[0063] An embodiment of the present disclosure provides a self-cleaning dust collecting sheet, in which at least a portion of the water tank is exposed to the outside of the self-cleaning dust collecting sheet body, making it convenient for users to attach and detach it, and 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.

[0064] In the related art, the self-cleaning dust collecting sheet fan is provided in a fan bin, the fan bin is provided at the bottom of the dust collecting bin, an air vent is formed at the bottom of the dust collecting bin, and the air inside the dust collecting bin is sucked out by the suction force generated when the fan is operated and discharged through the air duct in the fan bin to the outside of the self-cleaning dust collecting sheet main body 2000. Since the distance between the dust collecting port and the cleaning groove is relatively short, the robot may bring residual water in the cleaning groove into the dust collecting port in the process of climbing up and down the pile, and if there is too much water, it may be sucked into the dust collecting bin through the air duct during fan operation, and if too much water accumulates in the dust collecting bin, there is a risk of damage to the fan or electric shock.

[0065] Therefore, the embodiment of the present disclosure provides a self-cleaning dust collecting sheet, and a drainage hole is provided at the bottom of the dust collecting bin, so that the liquid in the dust collecting bin can be immediately discharged, and the same structure has the same technical effect, and some of the technical effects are not described here. Specifically, as shown in Fig. 6, the self-cleaning dust collecting sheet includes a self-cleaning dust collecting sheet bottom plate 1000 and a self-cleaning dust collecting sheet main body 2000, and the bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collecting sheet main body 2000, which is convenient for transportation. The self-cleaning dust collecting sheet body 2000 includes a dust collecting chamber 2100, and a dust collecting cover 2800 covers the dust collecting chamber 2100 to form a dust collecting bin 3000. The dust collecting chamber 2100 is integrally provided at the top end of the self-cleaning dust collecting sheet body 2000, and the dust collecting chamber 2100 is recessed inward at the top end of the self-cleaning dust collecting sheet body 2000 to form the dust collecting chamber 2100 for accommodating various parts for dust collection. The dust collecting chamber 2100 has a drainage hole 2101, which is provided at the bottom of the dust collecting chamber. The drainage hole 2101 may be one or more, and may be set according to the internal space of the dust collecting chamber 2100. Usually, the drainage hole 2101 is provided at the bottom of the dust collecting chamber. The self-cleaning dust collecting sheet body 2000 further includes an air duct 2500, one end of which is connected to the dust collecting port 6100 of the body base 6000 and the other end of which is connected to the dust collecting chamber 2100. A side wall of the dust collecting chamber 2100 includes an air inlet 2102, which is connected to the dust collecting port 6100 of the body base 6000 through the air duct 2500. The air duct is formed on the side wall of the self-cleaning dust collecting sheet body 2000 and extends downward, passing through the body base 6000 and connected to the dust collecting port 6100 of the body base 6000.Here, when the self-cleaning dust collecting sheet is in a dust collecting state, the internal airflow of the dust collecting bin 3000 is connected to the outside of the dust collecting bin 3000 through the air duct 2500, and the drain hole 2101 is not connected to the outside of the dust collecting bin 3000, so that a sufficient negative pressure is ensured within the dust collecting bin, and dust within the dust box is sucked into the dust collecting bag through the dust collecting port and the air duct. When the self-cleaning dust collecting sheet is in a non-dust collecting 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.

[0066] In some embodiments, the dust collection bin 3000 includes a drain valve 2103, which is provided 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 dust collection sheet is in a dust collection state, the drain valve 2103 closes the drain hole due to the action of negative pressure inside 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 dust collection sheet 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.

[0067] 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 screws, adhesives, clamps, 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, the drain hole 2101 is in an open state, and if there is water at the bottom of the dust collecting bin 3000, the water will be 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 if there is water in the dust collecting bin 3000, it will be discharged from the drain hole 2101 again.

[0068] In some embodiments, a sidewall of the dust collection bin 3000 includes a water baffle structure 2104 disposed at an edge of the air inlet 2102 and configured to block liquid entering through the air inlet. Specifically, the water baffle structure 2104 includes a first baffle wall 21041 extending laterally along an edge of the air inlet 2102 and a second baffle wall 21042 extending downwardly, the first baffle wall 21041 and the second baffle wall 21042 forming an air inlet region. In some embodiments, the second baffle wall 21042 extends downwardly at least to a lower edge of the air inlet 2102 to block liquid entering through the air inlet 2102.

[0069] In some embodiments, the self-cleaning dust collecting sheet 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 collecting bin 3000 and is used to accommodate the fan, the fan passage 2210 is configured to communicate the fan bin with the dust collecting bin and provide suction force by the fan, the fan 2220 is disposed within the fan bin and 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 by a preset distance along the bottom of the dust collecting bin 3000, and the fan passage 2210 protrudes from the bottom of the dust collecting bin 3000, thereby avoiding liquid entering the dust collecting bin 3000 from entering the fan bin 2200 and causing fan damage because it is not immediately discharged.

[0070] The self-cleaning dust collecting sheet body provided in this embodiment includes a dust collecting bin, and the dust collecting bin includes a drainage hole provided at the bottom of the dust collecting bin, and an air duct having one end connected to the bottom plate and the other end connected to the dust collecting bin. When the self-cleaning dust collecting sheet is in a dust collecting state, the air duct is connected to the outside of the dust collecting bin and the drainage hole is not connected to the outside of the dust collecting bin, so that a negative pressure state is ensured inside the dust collecting bin, which is convenient for dust collecting operation. When the self-cleaning dust collecting sheet is in a non-dust collecting state, the air duct is not connected to the outside of the dust collecting bin and the drainage hole is connected to the outside of the dust collecting bin, so that water that has entered into the dust collecting bin can be instantly discharged and damage to parts inside the dust collecting bin can be avoided.

[0071] In the related art, the fan in the self-cleaning dust collecting sheet vibrates greatly during the dust collecting process, which may damage the wall of the fan bin that comes into contact with it, and also causes loud noise due to the vibration.

[0072] Therefore, this embodiment provides a self-cleaning dust collecting sheet, 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, and some of the technical effects are not described here. Specifically, as shown in Fig. 7, the self-cleaning dust collecting sheet includes a bottom plate 1000 of the self-cleaning dust collecting sheet and a main body 2000 of the self-cleaning dust collecting sheet, the bottom plate 1000 of the self-cleaning dust collecting sheet is detachably or non-detachably connected to the main body 2000 of the self-cleaning dust collecting sheet, the main body 2000 of the self-cleaning dust collecting sheet includes a fan bin 2200, a fan 2220 and a vibration damping device 2230, and the fan bin 2200 is connected to the main body 2000 of the self-cleaning dust collecting sheet. 2200 is integrally provided inside the dust collecting bin 3000, 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 out gas enters the fan through the air inlet 2240 and is then discharged from the air outlet 2250. The fan 2220 is provided inside the fan bin 2200 and rotates forward or backward under the control of a control system. The vibration damping device 2230 is provided on at least a part of the outer surface of the fan 2220 and is used to reduce vibration of the fan 2220, and the vibration damping device 2230 may be made of an elastic material such as rubber or plastic.

[0073] In some embodiments, specifically as shown in Fig. 8, the vibration damping device 2230 includes a vibration damping cover 2231, which is 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 just provided to cover the fan top end. Specifically, in some embodiments, the vibration damping cover 2231 has a vibration damping cover top surface 22311, which includes a first opening 22312 adapted to the air inlet 2240 and a protruding edge 22313 extending outward along the first opening 22312, and is configured to be assembled between the top end of the fan 2220 and the air inlet 2240 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, thus, after the vibration damping cover 2231 is assembled to the top surface of the fan and assembled to the fan bin, the trumpet-shaped protruding edge 22313 is supported just around the fan bin air inlet, sealing the air inlet and reducing the impact of vibration and noise at the same time. In some embodiments, the vibration damping cover top surface 22311 may further include at least one protrusion extending continuously around the circumferential direction of the first opening 22312, configured to abut against the top inner wall of the fan bin 2200 to reduce the vibration of the fan 2220.

In some embodiments, the inside of the third protrusion 22316 has a plurality of discontinuous cavities, thereby further reducing the vibration of the fan.

[0074] 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.

[0075] 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 adapted to the air outlet and a plurality of second protruding beams 22321 extending laterally along the upper surface of the vibration-damping pad 2232, wherein the second protruding beam 22321 is a hollow structure, and a side wall 2231 of the second protruding beam 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 at 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 extending 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 fan bottom end air outlet structure 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.

[0076] According to the self-cleaning dust collecting sheet provided in this embodiment, the self-cleaning dust collecting sheet main body includes a fan installed in a fan bin, and a vibration damping device assembled to at least a part of the outer surface of the fan, and a plurality of vibration damping structures are provided in the vibration damping device, so that the effect of the vibration of the fan on the self-cleaning dust collecting sheet can be reduced.

[0077] In the related art, the cleaning module at the bottom of the automatic cleaning device (for example, 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. In addition, when 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 cannot climb up or leave the pile, especially when climbing up the pile of the automatic cleaning device, the driving force for climbing up the pile backwards is usually not large, so it cannot climb up the pile smoothly. In addition, when 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.

[0078] Therefore, the embodiment of the present disclosure provides a self-cleaning dust collecting sheet, and a lifting structure is provided on the bottom plate body, 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, and some of the technical effects are not described here.

[0079] Specifically, an example of a self-cleaning dust collecting sheet provided by an embodiment of the present disclosure is shown in Fig. 11 and Fig. 12 are diagrams illustrating the bottom plate of the self-cleaning dust collecting sheet connected to the main body base from different angles, and Fig. 13 is a schematic diagram illustrating the structure of the bottom plate of the self-cleaning dust collecting sheet.

[0080] As shown in FIG. 1, the self-cleaning dust collecting sheet provided in this embodiment includes a bottom plate 1000 of the self-cleaning dust collecting sheet and a main body 2000 of the self-cleaning dust collecting sheet.

[0081] The self-cleaning dust collecting sheet body 2000 is configured to collect dirt in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collecting sheet body 2000 may further be provided with components such as a dust collecting bin 3000, a clean water tank 4000, and a dirty water tank 5000. A body base 6000 is integrally provided below the self-cleaning dust collecting sheet body 2000. In some embodiments, the self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to the body base 6000 for convenient transportation.

[0082] In some embodiments, the body base 6000 below the self-cleaning dust collecting sheet 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 facilitate subsequent disposal of the dirt and wastewater. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100.

[0083] As shown in FIG. 11, the self-cleaning dust collecting sheet bottom plate 1000 includes a bottom plate body 1100 and a lifting structure 1300 .

[0084] The base plate body 1100 is configured to support the automatic cleaning device when the automatic cleaning device returns to the self-cleaning type dust collecting sheet base plate 1000. That is, the automatic cleaning device can move to the self-cleaning type dust collecting sheet base plate 1000 and be supported by the base plate body 1100. Specifically, in the process of the automatic cleaning device moving to the self-cleaning type dust collecting sheet base plate 1000, the drive wheels of the automatic cleaning device run on the inclined surface of the base plate body 1100.

[0085] 11 and 12 , 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.

[0086] 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.

[0087] In some embodiments, the angle between the top surface of the recess 1121 and the horizontal plane may be close to zero. The starting 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 bottom plate body 1100, which can prevent the automatic cleaning device from being obstructed or scraped by the surface of the bottom plate body 1100 during the process of climbing up or leaving the pile.

[0088] 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.

[0089] 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 coefficient corresponding to the predetermined inclination angle is called the first inclination coefficient. 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 coefficient corresponding to the predetermined inclination angle is called the second inclination coefficient. In some embodiments, the bottom plate body 1100 includes a recess 1121 and a protrusion 1122, and the second inclination coefficient is the inclination coefficient of the upper surface of the protrusion 1122 with respect to the horizontal plane. In some embodiments, the first inclination coefficient and the second inclination coefficient are related such that the first inclination coefficient is greater than the second inclination coefficient. The power of the automatic cleaning device immediately after climbing the pile is relatively small, and setting the second inclination coefficient to a small value is beneficial for the automatic cleaning device to climb the pile.

[0090] 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 dust collection sheet 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 connect and seal the dust collection port 6100 and the dust outlet of the automatic cleaning device to prevent dust leakage. The dust collection port 6100 is located on the upper surface of the main body base 6000, and is provided at approximately the edge position of the connection between the main body base 6000 and the bottom plate main body 1100.

[0091] 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 between the bottom plate body 1100 and the body base 6000. In some embodiments, the lifting structure 1300 is provided in the recess 1121 of the bottom plate body 1100. The lifting structure 1300 is configured to press the cleaning module on the bottom 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 dust collecting sheet body 2000) toward the self-cleaning dust collecting sheet 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 of the automatic cleaning device is pushed into the automatic cleaning device.

[0092] In the process of the automatic cleaning device retreating to the self-cleaning dust collecting sheet bottom plate 1000 along the opposite direction to the first direction X 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.

[0093] A lifting structure 1300 is provided on the upper surface of the bottom plate body 1100. In the process of the automatic cleaning device retreating to the self-cleaning dust collecting sheet bottom plate 1000 along the opposite direction X to connect the cleaning module of the automatic cleaning device with the cleaning groove of the self-cleaning dust collecting sheet 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 (for example, 8 mm). At this time, the cleaning module is pressed by the lifting structure 1300, and the cleaning module is lifted by the lifting structure 1300 of the automatic cleaning device. When the cleaning module moves inward (e.g., pushed into the automatic cleaning device by the lifting structure 1300), and then the automatic cleaning device continues to move backward along the opposite direction of 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, a part or all of the cleaning module is located above the dust collection port 6100, and the cleaning module can pass through the dust collection port 6100 in close contact with the dust collection port 6100. After the cleaning module completely passes through the dust collection port 6100, it gradually recovers to the state before being pressed by the lifting structure 1300 under the action of gravity, that is, 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 to the cleaning groove.

[0094] 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.

[0095] In some embodiments, the lifting structure 1300 includes a wedge member 1310 and a roller 1320 .

[0096] 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.

[0097] 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 retreats to the bottom plate body 1100 along the opposite direction to the first direction X, the automatic cleaning device can be gently pressed and quickly descended. Specifically, in some embodiments, the first angle α may be in the range of 5 degrees to 25 degrees, for example, 10 degrees to 15 degrees, so that when the automatic cleaning device retreats to the bottom plate body 1100 along the opposite direction to the first direction X, 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, 80 degrees to 85 degrees, so that the frame of the cleaning module quickly descends under the action of gravity after it is released from the lifting structure 1300.

[0098] 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.

[0099] The roller 1320 is provided on the first top surface 1313 and is in rolling contact with the cleaning module in the process of pressing the cleaning module on the bottom surface of the automatic cleaning device to move the cleaning module toward the inside of the automatic cleaning device. The provision of the roller 1320 can reduce the frictional resistance between the frame of the cleaning module and the wedge-shaped member 1310, reduce the wear between the components, and extend the service life of each component.

[0100] In some embodiments, a portion of the roller 1320 may be embedded within the wedge 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 member 1310 to facilitate replacement of the roller 1320.

[0101] In some embodiments, the number of the 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 of the automatic cleaning device retreating to the base plate body 1100 in the opposite direction to the first direction X, the at least two lifting structures 1300 are respectively abutted against the frame of the cleaning module, and 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 displaced in the second direction Y due to uneven force.

[0102] 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.

[0103] In some embodiments, the self-cleaning dust collecting sheet bottom plate 1000 further includes a slope body 1400, which may be a slope and is provided on the surface of the bottom plate body 1100. Specifically, the slope body 1400 may be provided at the edge position of the connection part of the bottom plate body 1100 and the body base 6000, and is provided approximately in front of the dust collecting port 6100 and at the central axis position of the bottom 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 bottom 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 collecting port 6100 when the automatic cleaning device is climbing up the pile.

[0104] In some embodiments, the ramp 1400 is provided in a recess 1121 of the base plate body 1100. In some embodiments, as shown in Fig. 13, the ramp 1400 and the lifting structure 1300 are both provided in a 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 ramp 1400 and the lifting structure 1300 in the recess 1121, it is possible to avoid the automatic cleaning device being blocked by or rubbed against the surface of the base plate body 1100 during the process of climbing up or leaving the pile.

[0105] In some embodiments, the lifting structure 1300 is provided in a recess 1121 of the base plate body 1100, and the height of the lifting structure 1300 is greater 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.

[0106] 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.

[0107] In some embodiments, the lifting structure 1300 has a preset distance from the stop end of the base plate body 1100, and due to the preset distance, when the automatic cleaning device enters the self-cleaning dust collecting sheet base plate 1000 from the rear, if the driving wheel of the automatic cleaning device does not enter the stop end of the base plate body 1100, the lifting structure 1300 will not contact the cleaning module. 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 in climbing the pile. 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.

[0108] The present disclosure further provides an automatic cleaning device and a dust collection system comprising the self-cleaning dust collection sheet of the above embodiment.

[0109] The self-cleaning dust collection sheet and dust collection system provided by the embodiments of the present disclosure are provided with a lifting structure on the base plate body, which can avoid the phenomenon that the cleaning module is rubbed or stuck when the automatic cleaning device is climbing up or off the pile, and thus can improve the success rate of the automatic cleaning device climbing up or off the pile.

[0110] In the related art, the structure of the air duct of the self-cleaning dust collecting sheet is usually complicated, which occupies more physical space and makes the self-cleaning dust collecting sheet look bulky. In addition, the complicated air duct structure also reduces the dust collecting effect to a certain extent, and it is difficult to suck all the garbage in the dust box into the dust collecting chamber of the self-cleaning dust collecting sheet.

[0111] Therefore, an embodiment of the present disclosure provides a self-cleaning dust collecting sheet, optimizes the air duct structure inside the self-cleaning dust collecting sheet, and shortens the air duct path, making the air duct of the self-cleaning dust collecting sheet smoother and more compact in structure, thereby further improving the dust collection efficiency of the automatic cleaning device.

[0112] Specifically, an example of a self-cleaning dust collecting sheet 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 dust collecting sheet, and Fig. 15 and Fig. 16 are diagrams showing the air duct structure of the self-cleaning dust collecting sheet and the air flow direction in the air duct in the dust collecting state.

[0113] As shown in Fig. 14, the self-cleaning dust collecting sheet provided in this embodiment includes a self-cleaning dust collecting sheet bottom plate 1000 and a self-cleaning dust collecting sheet body 2000. Here, the self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collecting sheet body 2000, and specifically, the self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to a body base 6000 at the bottom of the self-cleaning dust collecting sheet body 2000. The detachable connection method can facilitate transportation and maintenance.

[0114] The self-cleaning dust collecting sheet body 2000 is configured to collect dirt in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collecting sheet body 2000 is provided with components such as a dust collecting 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 dust collecting sheet body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 is open upward and forward and is provided at the top of the self-cleaning dust collecting sheet body 2000, and the water storage chamber further includes 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 open upward and forward and is provided at the top end of the self-cleaning dust collection sheet 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 clean water tank 4000 and the dust collection cover 2800.

[0115] There is a body base 6000 below the self-cleaning dust collecting sheet body 2000. In some embodiments, the body base 6000 is integrally provided below the self-cleaning dust collecting sheet body 2000. The body base 6000 is further abutted against the bottom plate 1000 of the self-cleaning dust collecting sheet, specifically, the bottom plate 1000 of the self-cleaning dust collecting sheet and the body base 6000 are sequentially provided along a second direction, which is opposite to the arrow of the front-rear axis X.

[0116] 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 portion between the main body base 6000 and the bottom plate 1000 of the self-cleaning dust collection sheet. 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 dust collection sheet 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 connecting them 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 can be denoted as a length L1. The dust collection port 6100 extends along the first direction and also extends along a second direction, and the second direction is the width direction of the dust collection port 6100, and the extension distance of the dust collection port 6100 in the second direction can be denoted as a width W1, and further, there is a relationship between the length L1 and the width W1, that is, L1>W1.

[0117] In some embodiments, the body base 6000 further includes a cleaning groove 6200, which is configured to clean the cleaning member on the automatic cleaning device, for example, to replenish cleaning liquid 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, 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 dust collecting sheet body 2000 along the second direction, and a side wall may be formed between the self-cleaning dust collecting sheet body 2000 and the cleaning groove 6200.

[0118] 15 and 16, the self-cleaning dust collecting sheet 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 dust collecting sheet is in a dust collecting 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 air duct 2510 and a base air duct 2520 according to its location. The base air duct 2520 is substantially located at the position shown in the dashed frame in the lower right corner of FIG. 15, and the main air duct 2510 is substantially located at the position shown in 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.

[0119] Specifically, 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 dust collecting sheet main body 2000. Specifically, the base air duct 2520 communicates with the longitudinal direction of the dust collection port 6100 and extends along a first direction to approximately the edge position of the main body base 6000, and then extends along a second direction to the main body air duct 2510. 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 by the airflow directly flows out from one end of the longitudinal direction of the dust collection port 6100 and then 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, if the cross section of the air duct is circular or close to circular, the width of the air duct in this case is the diameter of the circle or the length of the major axis of the ellipse. By appropriately reducing the width of the base air duct 2520, the air flow rate 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, thereby avoiding clogging of the base air duct 2520 and improving the dust collection effect. In some embodiments, in the base air duct 2520, the curved sections extending along the first direction and the curved sections extending along the second direction are smoothly connected in an arc shape, and the first direction and the second direction are approximately perpendicular, but the bends in the base air duct 2520 in the first direction and the second direction are not bent at right angles, but are replaced by 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 sudden changes in flow speed.Similarly, in the base air duct 2520, the curved portion extending along the second direction and the curved portion extending upward of the main air duct 2510 are smoothly connected in an arc shape.

[0120] The main air duct 2510 is provided at least on a side wall of the self-cleaning dust collecting sheet body 2000, one end of the main air duct 2510 communicates with the base air duct 2520 and the other end leads to the dust collecting chamber 2100, and the main air duct 2510 communicates with the base air duct 2520 and the dust collecting chamber 2100. Specifically, the main air duct 2510 extends upward along the side wall of the self-cleaning dust collecting sheet body 2000 to the dust collecting bin 3000, and the side wall to which the main air duct 2510 extends may be formed by the side edge of the cleaning groove 6200 and the side edge of the self-cleaning dust collecting sheet body 2000, and the above design of the main air duct 2510 can fully utilize the vacant space between the self-cleaning dust collecting sheet body 2000 and the cleaning groove 6200 to make 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 air flow velocity 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.

[0121] In some embodiments, the main air duct 2510 and the base air duct 2520 are two independent structures, connected by a connector, the separate structures can facilitate the maintenance of the pipeline, especially when the pipeline is clogged, in some embodiments, the main air duct 2510 and the base air duct 2520 are an integral structure, the integral structure can effectively avoid the leakage of airflow in the air duct.

[0122] The present disclosure further provides an automatic cleaning device and a dust collection system comprising the self-cleaning dust collection sheet in the above embodiment.

[0123] 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 inlet 320, where the air inlet 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 dust collecting sheet main body 2000, and the dust inlet 310 is connected to a dust outlet of the automatic cleaning device.

[0124] Under dust collection state, the air inlet 320 of the dust box 300 is opened, and the first fan on the self-cleaning dust collecting sheet starts to work, sucking out the gas in the dust collecting chamber 2100 and the air duct 2500, and the air pressure in the dust collecting chamber 2100 and the air duct 2500 drops, 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 collecting port 6100 of the self-cleaning dust collecting sheet and the air duct 2500, and the airflow lifts up the dirt in the dust box 300, and the dirt in the dust box 300 is lifted up by the airflow and finally sucked into the dust collecting 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 dirt in the dust box to be discharged from the dust box and enter the dust collecting bin through the air duct.

[0125] According to the self-cleaning dust collecting sheet and dust collecting system provided by the embodiments of the present disclosure, by optimizing the air duct structure inside the self-cleaning dust collecting sheet, the air duct path is made smaller, the air duct of the self-cleaning dust collecting sheet is made smoother, the structure is compact, and the dust collection efficiency of the automatic cleaning device can be further improved.
