[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. Obviously, the described embodiments are only some embodiments of the present disclosure, and 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 particular embodiments and are not intended to limit the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" are also intended to encompass the plural, and "plurality" generally includes at least two, unless the context clearly indicates otherwise.

[0014] The term "and / or" used in this specification merely describes 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 the embodiments of the present disclosure, terms such as "first," "second," and "third" may be used for explanatory purposes, but it should be understood that these terms are not intended to be limiting. These terms are used only for distinction. For example, a "first" may also be called a "second," and similarly, a "second" may also be called a "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 comprising a set of elements not only includes those elements, but also other elements explicitly listed or inherent in those products or devices. Unless further limited, an element defined as "comprising" 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 placed inside the complex hood cover of the self-cleaning dust collecting sheet, making it difficult to remove and use, and the water tank connection port is formed at the bottom of the water tank, making it easy for the water in the water tank to overflow, which is very likely to damage parts in the self-cleaning dust collecting sheet. Furthermore, the air duct of the self-cleaning dust collecting sheet is also too complicated, making it difficult for dust to enter the dust box from the dust collecting bin.

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

[0020] 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: a transverse axis Y, a front-to-rear axis X, and a central vertical axis Z. The direction opposite the arrow along the front-to-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 along the arrow along the front-to-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 upward 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 main body of the self-cleaning dust collecting sheet is the front, the direction toward the rear wall of the main body of the self-cleaning dust collecting sheet 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 dust collecting chamber 2100. 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 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. Typically, 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 above, which structural design is in line with user habits. Furthermore, the open upward and forward design 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 portion of which is provided on a side wall of the self-cleaning dust collecting sheet body 2000. The air duct 2500 connects the body base 6000 at the bottom of the self-cleaning dust collecting sheet body 2000 with the dust collection chamber 2100. During the dust collection process, dust in the dust box enters the air duct 2500 through the dust collection port of the body base 6000 and then enters the dust collection chamber 2100 via the air duct 2500. The self-cleaning dust collecting sheet body 2000 is configured to collect dust in the dust box of the automatic cleaning device. The self-cleaning dust collecting sheet main body base 6000 has a dust collection opening 6100, which is connected to the dust outlet of the automatic cleaning device, and dust in the dust box of the automatic cleaning device enters the dust collection bin 3000 of the self-cleaning dust collecting sheet main body 2000 through the dust collection opening 6100. A sealing rubber gasket is further provided around the dust collection opening 6100 to connect and seal the dust collection opening 6100 and the dust outlet of the automatic cleaning device, thereby ensuring the dust collection 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, front wall and a number of side walls of the self-cleaning dust collection sheet main 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 collection sheet main body 2000 is higher than the height of the front wall of the self-cleaning dust collection sheet main body 2000, the side walls of the self-cleaning dust collection sheet main body 2000 are connected to the rear wall and the front wall, and the end faces of the side walls of the self-cleaning dust collection sheet main 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 wastewater tank 5000 and the clean water tank 4000, and the water storage chamber 2700 abuts against the rear wall of the water storage chamber 2700 and includes a boss 2600 extending 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, which are configured to be connected to the wastewater tank 5000 or the clean water tank 4000 assembled in the corresponding position. Here, the water storage chamber 2700 includes a vertically extending partition plate 2710, which divides the water storage chamber 2700 into two parts: one part is the wastewater chamber 2300 for accommodating the wastewater 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 openings include 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. The air pump sucks out air from the wastewater tank 5000 through the air pump port 2610. Because 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. 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, thereby cleaning the cleaning head of the automatic cleaning device. The air pump port 2610, the waste water tank connection port 2620, and the clean water tank connection port 2630 are located at the top of the boss 2600, thereby preventing the water in the clean water tank or the waste water tank from overflowing and flowing into the clean water chamber or the waste water chamber during the process of replacing the clean water tank or the waste water tank. The top-sealed connection of the air pump port 2610, the waste water tank connection port 2620, and the clean water tank connection port 2630 to the waste water tank 5000 and the clean water tank 4000 is more convenient for operation than a connection at the bottom of the clean water chamber or the waste 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 their front surfaces are substantially flush with each other. After being assembled to the self-cleaning dust collecting sheet main body 2000, the dirty water tank 5000, the clean water tank 4000 and the dust collecting cover 2800 form a flat arrangement structure, which on the one hand makes it easy to attach and detach and use, and on the other hand, the flat outline improves aesthetics and enhances the user experience.

[0028] When a self-cleaning dust collection sheet is used for a long period of time, the soft rubber protrusion openings will inevitably become contaminated by dirty water from cleaning members, leaving behind dirt. With the above design, the soft rubber protrusion openings on boss 2600 have an open structure relative to the front wall and also to the side wall, allowing arms and cleaning tools to access the soft rubber protrusion openings from any angle, making it easy for users to clean the dirt that has 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 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 body, and most of the dust collecting cover is located outside the dust collecting chamber. The above design reduces the amount of material used in the self-cleaning dust collecting sheet body, 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 on the top of the sewage tank, clean water tank, and dust collecting cover, facilitating operation of the sewage tank, clean water tank, and dust collecting chamber, while also achieving the technical effect of an aesthetically pleasing design. 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, so that 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, allowing people to easily observe the water levels in the transparent sewage tank and clean water tank and the situation in the dust collecting chamber, and to timely perform corresponding operations on 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. The sealed connection completely seals the inside of the dust collection bin, contributing to improved dust collection efficiency.

[0031] A cleaning chamber with an opening to the front 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 it returns to the self-cleaning dust collecting sheet for maintenance. 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, such as a sweeping robot, has completed cleaning and returned to the self-cleaning dust collecting sheet, 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 non-detachable whole, 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 within the automatic cleaning device. The air inlet of the dust collection duct is a dust collection port, and the air outlet of the dust collection duct communicates with the dust collection chamber 2100 via an air duct 2500.

[0034] In the 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 complicated, the water tank is placed inside a complex hood cover of the self-cleaning dust collecting sheet, making it difficult to remove and use, and the water tank connection port is formed at the bottom of the water tank, making it easy for the water in the water tank to overflow, which is very 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 portion of the water tank to the outside of the self-cleaning dust collecting sheet body, it is easy for users to attach and detach, and by locating the water tank's water inlet at the top of the water tank, it is difficult for the liquid in the water tank 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 below: Fig. 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collecting sheet, Fig. 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 collection cover of the present disclosure, and 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 self-cleaning dust collecting sheet bottom plate 1000, a self-cleaning dust collecting sheet main body 2000, and a water storage tank 7000. Here, in order to facilitate transportation and maintenance of the self-cleaning dust collecting sheet bottom plate 1000 and the self-cleaning dust collecting sheet main body 2000, the self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collecting sheet main body 2000, and the water storage tank 7000 is assembled to the top end of the self-cleaning dust collecting sheet main body 2000.

[0039] 2 , the self-cleaning dust collecting sheet body 2000 includes a water storage chamber 2700, which opens upward and forward and is located 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 the clean water tank 4000 or the dirty water tank 5000. There may be multiple water storage tanks 7000. In some embodiments, the self-cleaning dust collecting sheet body 2000 includes two water storage tanks 7000, one for the clean water tank 4000 and one for the dirty water tank 5000, and correspondingly, the water storage chambers include a clean water chamber 2400 for storing the clean water tank 4000 and a dirty water chamber 2300 for storing 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 main body 2000 from the front and top, which is more in line with the user's usage habits and makes it easier to attach and detach the water tank 7000. Furthermore, the upward and front opening design makes it easier to perform routine maintenance on the components inside the water chamber 2700.

[0040] The water storage chamber 2700 is formed by the rear wall, front wall, and multiple side walls of the self-cleaning dust collecting sheet body 2000, where the rear wall of the self-cleaning dust collecting sheet body 2000 is higher than 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 ensures the stability and aesthetic appearance 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 plurality of soft rubber protrusion openings are provided on the top of the boss 2600, and the soft rubber protrusion openings 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 from 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 waste water tank connection port 2620, and the clean water tank connection port 2630 are located at the top of the boss 2600 to prevent the water in the clean water tank or the waste water tank from overflowing and flowing into the clean water chamber or the waste water chamber during the process of replacing the clean water tank or the waste water tank. The top-sealed connection of the air pump port 2610, the waste water tank connection port 2620, and the clean water tank connection port 2630 to the waste water tank 5000 and the clean water tank 4000 is more convenient for operation than connection at the bottom of the clean water chamber or the waste water chamber.

[0046] When a self-cleaning dust collection sheet is used for a long period of time, the soft rubber protrusion openings will inevitably become contaminated by dirty water from cleaning the cleaning members, leaving behind dirt. With the above design, the soft rubber protrusion openings on the boss 2600 have an open structure relative to the front wall and also to the side wall, allowing the arm or cleaning tool to access the soft rubber protrusion openings from any angle, making it easy for the user to clean the dirt that has 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 protrusions 2640, which correspond to and fit into 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 protrusions 2640 of the water chamber 2700 are locked into the pits 7221 of the water tank 7000. The specific number of soft rubber protrusions 2640 may be determined according to actual circumstances, and the soft rubber protrusions 2640 may be symmetrically distributed on the top of the boss 2600. For example, in one embodiment, there are four soft rubber protrusions 2640, which are distributed approximately evenly on the top of the boss 2600. The cooperation and restriction of the soft rubber protruding points 2640 and the pits 7221 allows the water tank 7000 to be positioned more accurately within the water chamber 2700, and prevents the water tank 7000 from shifting out of position.

[0048] The water chamber 2700 may further include a vertically extending partition plate 2710 that divides the water chamber 2700 into two parts, one part being a dirty water chamber 2300 for accommodating the dirty water tank 5000, and the other part being a clean water chamber 2400 for accommodating the 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 it 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, so that 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 to the top end of the self-cleaning dust collecting sheet main 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 routinely replace the liquid in the water tank 7000. The water tank 7000 may adopt a transparent material so that the liquid level in the water tank 7000 can be observed.

[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. This design further optimizes the attachment and detachment of the water tank 7000, facilitating users' daily replacement of the liquid in the water tank 7000, and reducing the amount of material used in the self-cleaning dust collecting sheet body 2000. Furthermore, 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 part of the water chamber 2700 is also exposed to the outside of the cavity, allowing users to easily observe the water level in the transparent water chamber 2700 and perform corresponding operations on the water chamber 2700.

[0051] The water storage tank 7000 may be the clean water tank 4000 or the dirty water tank 5000. There may be more than one water storage tank 7000. In some embodiments, the self-cleaning dust collecting sheet main body 2000 includes two water storage tanks 7000, one for the clean water tank 4000 and the other for the dirty water tank 5000. The dirty water tank 5000 and the clean water tank 4000 are arranged side by side in the water storage chamber 2700, with the top surfaces of the dirty water tank 5000 and the clean water tank 4000 being substantially flush with each other, and their front surfaces being substantially flush with each other. After the dirty water tank 5000 and the clean water tank 4000 are assembled to the self-cleaning dust collecting sheet main body 2000, they form a flat array structure, which on the one hand facilitates installation and removal and use, and on the other hand, the flat profile improves aesthetics and enhances the user experience.

[0052] The water tank 7000 has an opening for the inflow and outflow of liquid. The opening is located at the top of the tank body, and its height 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. If the water tank 7000 is a dirty water tank 5000, the opening is a dirty water port. If 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, which can prevent liquid overflow, especially during the water tank replacement process. Furthermore, damage to electronic components due to 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 covering the water tank accommodating portion 7100, the water tank accommodating portion 7100 including a water tank main body portion 7130 and a water tank protrusion 7140, the water tank top cover 7200 forming a cavity together with the water tank accommodating portion 7100, the water tank protrusion 7140 protruding from the water tank main body portion 7130, and the water tank having 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, and the recess 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 above a maximum water level line 7111, and a second recess 7120 extending upward along the bottom of the water tank housing to above a predetermined height, and the height of the second recess 7120 is not limited. Here, the first recess 7110 is confined 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 protrusion 7140, the top surface of the first recess 7110 includes a clean water port, a sewage port or a pit 7221, etc., and is connected to the air pump port 2610, the sewage tank connection port 2620, the clean water tank connection port 2630 or the soft rubber protrusion point 2640 provided on the boss 2600, and the second recess 7120 is confined in cooperation with a protrusion on the inner side wall of the water chamber 2700. The recess provided in the water tank receiving portion 7100 achieves overall confinement of the water tank 7000, allowing the water tank 7000 to be positioned relatively accurately in the corresponding position of the water chamber 2700, and preventing the water tank 7000 from being misaligned.

[0055] The top cover 7200 covers the top of the water tank housing portion 7100, is detachably connected to the water tank housing portion 7100, and can be opened and closed relative to the water tank housing portion 7100. When the top cover 7200 is closed, the liquid in the water tank housing portion 7100 is isolated from the outside, and it is possible to prevent external foreign matter from falling 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 portion 7100, and the top cover 7200 forms a sealed structure together with the water tank housing portion 7100.

[0056] A clean water port, a sewage port or a pit 7221, etc. are provided on the underside of the water tank protrusion 7140. If the water tank 7000 is a sewage tank 5000, a sewage port is provided on the underside of the water tank protrusion 7140. If 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 to the water chamber 2700, the water tank protrusion 7140 is supported by the boss 2600 in the water chamber 2700, and the sewage port or clean water port provided on the underside of the water tank protrusion 7140 is connected to the soft rubber protrusion opening on the top of the boss 2600.

[0057] In some embodiments, the water storage tank 7000 is the wastewater tank 5000, and an air pump connector is further provided on the underside of the water tank protrusion 7140, which is connected to the air pump connection port 2610 at the top of the boss 2600. After the air pump connection port 2610 is connected to the air pump connector, it can suck wastewater from the wastewater tank 5000. In some embodiments, the air pump sucks out air from the wastewater tank 5000 through the air pump connection port 2610 and the air pump connector. Because the wastewater tank 5000 has a sealed structure, negative pressure is created 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.

[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 supported by the boss 2600 in the water chamber 2700, and the plurality of pits 7221 on the underside of the water tank protrusion 7140 cooperate with the soft rubber protrusion points on the top of the boss 2600 to restrict the water tank 7000. The cooperation and restriction between the soft rubber protrusion points 2640 and the pits 7221 ensures a more accurate positioning of the water tank 7000 within the water chamber 2700, and prevents the water tank 7000 from shifting out of position.

[0059] 5 , in some embodiments, the water storage tank 7000 is the clean water tank 4000, which further includes a water pipe bracket 7300 and a water pipe 7400. The water pipe bracket 7300 is attached to a protruding structure 7900 in the clean water tank 4000, which corresponds to the first recess 7110 and is higher than the maximum water level 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, allowing liquid to flow through the water pipe 7400 to the outside of the clean water tank 4000. 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 and the water pipe outlet is located at the water pipe bracket 7300 and connected to the clean water inlet of the clean water tank 4000.

[0060] In some embodiments, the water tank 7000 is the clean water tank 4000, and in this case, the water tank 7000 may further include a float ball base 7500 and a float ball 7600. Here, the float ball base 7500 is provided at the bottom of the clean water tank 4000 and is used to position the float ball 7600, and the float ball 7600 is connected to the float ball base 7500, can rotate around a fixed axis of the float ball 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, in which case 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 hingedly connected to the top of the water tank 7000. The handle 7800 makes it easier to attach and detach the water tank 7000, making it easier for a user to routinely replace the liquid in the water tank 7000.

[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 easy for users to attach and detach. The water tank's water inlet is located at the top of the water tank, making it less likely for the liquid in the water tank to overflow, and thus preventing damage to electronic components caused by the overflowing liquid.

[0064] In the related art, the self-cleaning dust collecting sheet fan is mounted in a fan bin, which is mounted at the bottom of the dust collecting bin, and a vent hole is formed at the bottom of the dust collecting bin, and when the fan is operated, suction force is generated to suck air out of the dust collecting bin and discharge it through an air duct in the fan bin to the outside of the self-cleaning dust collecting sheet main body 2000. Because the distance between the dust collection opening and the cleaning groove is relatively short, residual water in the cleaning groove may be brought into the dust collection opening when the robot climbs up or leaves the pile, and if there is too much water, it may be sucked into the dust collecting bin through the air duct when the fan is operating, 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, an embodiment of the present disclosure provides a self-cleaning dust collecting sheet, and by providing a drainage hole at the bottom of the dust collecting bin, liquid that has entered the dust collecting bin can be immediately discharged. Similar structures have similar technical effects, and some of the technical effects will not be described here. Specifically, as shown in Figure 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, making it 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 components 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 communicates with the dust collection port 6100 of the body base 6000 and the other end of which communicates with the dust collection chamber 2100. The side wall of the dust collection chamber 2100 includes an air inlet 2102, which communicates with the dust collection port 6100 of the body base 6000 via the air duct 2500. The air duct is formed on the side wall of the self-cleaning dust collecting sheet body 2000, extends downward, and passes through the body base 6000 to communicate with the dust collection 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 maintained inside the dust collecting bin, and dust in 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 drain 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 drain 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 the fan.

[0066] In some embodiments, the dust collection bin 3000 includes a drain valve 2103, which is located at an outlet position near the drain hole 2101 on the outside of the bottom of the dust collection bin 3000. 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. 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 bottom of the dust collection bin 3000 by screws, adhesive, clamps, etc., and the elastic movable end 21032 is located at the outlet of the drain hole 2101 and can be switched between an open state and a closed state. The elastic movable end 21032 is made of a soft rubber stopper material such as rubber or plastic. Under normal conditions, the drain hole 2101 is open, and if there is water at the bottom of the dust collection bin 3000, the water will automatically drain through the drain hole 2101. When the fan is operating, negative pressure is created within the dust collection bin 3000, and the elastic movable end 21032 is automatically attracted to the outside of the drain hole to seal it. After the fan is stopped, the elastic movable end 21032 will automatically open under the action of gravity, and if there is water in the dust collection bin 3000, it will again drain through the drain hole 2101.

[0068] In some embodiments, a sidewall of the dust collection bin 3000 includes a water baffle structure 2104, which is disposed on 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 the edge of the air inlet 2102 and a second baffle wall 21042 extending downward, 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 downward at least to the lower edge of the air inlet 2102 and blocks 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, wherein the fan bin 2200 is disposed below the dust collecting bin 3000 and is used to house the fan, the fan passage 2210 connects the fan bin and the dust collecting bin and is configured to provide suction force via the fan, and the fan 2220 is disposed within the fan bin, can be turned on / off under the control of a control system, and is used to provide the suction force required for dust collection. In some embodiments, the fan passage 2210 extends upward a predetermined 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 preventing liquid that enters the dust collecting bin 3000 from entering the fan bin 2200 and causing damage to the fan due to the liquid not being immediately discharged.

[0070] The self-cleaning dust collecting sheet body provided in this embodiment includes a dust collecting bin, which includes a drainage hole at the bottom of the dust collecting bin and an air duct with one end communicating with the bottom plate and the other end communicating with the dust collecting bin. When the self-cleaning dust collecting sheet is in a dust collecting state, the air duct communicates with the outside of the dust collecting bin and the drainage hole does not communicate with the outside of the dust collecting bin, thereby ensuring a negative pressure state inside the dust collecting bin and facilitating dust collection. When the self-cleaning dust collecting sheet is in a non-dust collecting state, the air duct does not communicate with the outside of the dust collecting bin and the drainage hole communicates with the outside of the dust collecting bin, allowing water that has entered the dust collecting bin to be immediately discharged and preventing damage to components inside the dust collecting bin.

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

[0072] Therefore, this embodiment provides a self-cleaning dust collecting sheet, and a plurality of vibration damping devices are provided in the fan bin to reduce the vibration caused by the rotation of the fan. Similar structures have similar technical effects, and some of the technical effects will not be described here. Specifically, as shown in Figure 7, 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. The self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collecting sheet main body 2000. The self-cleaning dust collecting sheet main body 2000 includes a fan bin 2200, a fan 2220, and a vibration damping device 2230. The fan bin 2200 is connected to the self-cleaning dust collecting sheet main body 2000. Fan bin 2200 is integrally mounted inside dust collection bin 3000 and includes an air inlet 2240 and an air outlet 2250. Air inlet 2240 communicates with dust collection bin 3000 through fan passage 2210 and is used to draw in air by fan rotation, suck out gas within dust collection bin 3000, and maintain negative pressure within dust collection bin 3000. The sucked gas enters the fan through air inlet 2240 and is then discharged through air outlet 2250. Fan 2220 is mounted within fan bin 2200 and rotates forward or backward under the control of a control system. Vibration damping device 2230 is mounted on at least a portion of the outer surface of fan 2220 and is used to reduce vibration of fan 2220. Vibration damping device 2230 may be made of an elastic material such as rubber or plastic.

[0073] 8 , the vibration damping device 2230 includes a vibration damping cover 2231, which is assembled to at least a portion of the top end of the fan 2220 to reduce vibration of the fan, and the outer shape of the vibration damping cover 2231 is adapted to the fan top end structure, so that the vibration damping cover 2231 just covers 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 assembled between the top end of the fan 2220 and the air inlet 2240 to reduce vibration of the fan. In some embodiments, the opening area of ​​the protruding edge 22313 gradually increases as the distance the protruding edge extends outward increases, so that after the vibration-damping cover 2231 is assembled to the top surface of the fan and then to the fan bin, the horn-shaped protruding edge 22313 is supported exactly around the periphery of the fan bin air inlet, sealing the air inlet and reducing the effects of vibration and noise. 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, which is configured to abut against the top inner wall of the fan bin 2200 to reduce vibration of the fan 2220. In some embodiments, the vibration-damping cover top surface 22311 may further include a first protrusion 22314, a second protrusion 22315, and a third protrusion 22316 extending continuously around the circumferential direction of the first opening 22312. A groove 22317 is provided between the second protrusion 22315 and the third protrusion 22316 and extending continuously around the circumferential direction of the first opening 22312. The first protrusion 22314, the second protrusion 22315, the third protrusion 22316, and the groove 22317 are extruded and deformed during assembly, reducing the rigid connection between the fan and the fan bin and further reducing vibration damage. In some embodiments, the third protrusion 22316 has a plurality of discontinuous cavities inside, further reducing vibration of the fan.

[0074] In some embodiments, as shown in FIG. 8 , the vibration-damping cover includes vibration-damping cover side walls 22318 that extend downward 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 side walls 22318 enclose the sides of the fan, and the vibration-damping cover side walls 22318 include a plurality of spaced-apart first protruding beams 22319 that are hollow, and the outer walls of each first protruding beam 22319 abut against the side walls of the fan bin 2200, thereby 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, which is assembled to at least a portion of the bottom end of the fan 2200 to reduce vibration of the fan 2200. In some embodiments, as shown in FIG. 10 , the vibration-damping pad 2232 includes a second opening 22322 that fits into the air outlet and a plurality of second protruding beams 22321 that extend laterally along the upper surface of the vibration-damping pad 2232, where the second protruding beams 22321 are hollow and the side walls 2231 of the second protruding beams contact the bottom of the fan 2200 to further reduce vibration of the fan. After the vibration-damping pad 2232 is assembled to the bottom of the fan 2200, the air outlet structure at the bottom of the fan enters the second opening 22322, and the bottom of the fan is engaged with the assembly protrusions 22324 of the vibration-damping pad 2232 by an interference fit, so that the flat surface of the bottom of the fan comes into contact with the plurality of second protruding beams 22321 that extend laterally along the upper surface of the vibration-damping pad 2232, where the hollow second protruding beams 22321 play a role in reducing vibration. 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, which further reduces the vibration of the fan.

[0076] According to the self-cleaning dust collecting sheet provided in this embodiment, the self-cleaning dust collecting sheet body includes a fan installed in a fan bin and a vibration damping device assembled on at least a part of the outer surface of the fan, and the vibration damping device is provided with a plurality of vibration damping structures, thereby reducing the impact of the vibration of the fan on the self-cleaning dust collecting sheet.

[0077] In related art, the cleaning module at the bottom of the automatic cleaning device (e.g., the mop cloth bracket of a wet cleaning module) typically has a lifting structure and does not adhere to the bottom of the automatic cleaning device under natural gravity. Furthermore, if the dust collection port of the automatic cleaning device is located 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. When passing through the dust collection port, the cleaning module (especially the mop cloth bracket) is likely to get caught on the dust collection port, preventing the automatic cleaning device from climbing up or leaving the pile. In particular, when the automatic cleaning device climbs up the pile, the driving force for climbing backward is usually not large, preventing it from climbing up the pile smoothly. Furthermore, if the cleaning module is a wet cleaning module, the mop cloth, which has just been washed, is not completely dry. When it rubs against the dust collection port, the water on the mop cloth is sucked into the dust collection port and then into the dust collection box, causing damage to 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 base plate body to prevent the cleaning module from being scraped or stuck when the automatic cleaning device is climbing up or leaving the pile, and further improve the success rate of the automatic cleaning device climbing up or leaving the pile. Similar structures have similar technical effects, and some of the technical effects will not be 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, which 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 dust in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collecting sheet body 2000 may be further provided with components such as a dust collection bin 3000, a clean water tank 4000, and a dirty water tank 5000. A body base 6000 is integrally provided below the self-cleaning 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 main body base 6000 below the self-cleaning dust collection sheet main 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 located behind the dust collection port 6100.

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

[0084] The base plate body 1100 is configured to support the automatic cleaning device when it returns to the self-cleaning dust collecting sheet base plate 1000. That is, the automatic cleaning device can move to the self-cleaning dust collecting sheet base plate 1000 and be supported by the base plate body 1100. Specifically, during the process of the automatic cleaning device moving to the self-cleaning 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 main body base 6000 and the base plate body 1100 are sequentially arranged along the first direction X, and the base plate 1000 is connected to the main body base 6000. Specifically, along the first direction X, the main body base 6000 has a start end and a stop end, and the base plate body 1100 also has a start end and a stop end, with the stop end of the main body base 6000 abutting against the start end of the base plate body 1100. In some embodiments, the main body base 6000 is detachably or non-detachably connected to the base plate body 1100, which is convenient for transportation.

[0086] The main body base 6000 and the base plate main body 1100 form a continuous inclined surface at least along the first direction X, allowing the drive wheels of the automatic cleaning device to run relatively smoothly thereon. In some embodiments, the drive wheels of the automatic cleaning device are located on both sides of the bottom, and the main body base 6000 and the base plate main body 1100 correspondingly form a continuous inclined surface adapted to the positions of the drive wheels, allowing the drive wheels to run thereon. In some embodiments, the base plate main body 1100 further includes a recess 1121 and a protrusion 1122, where the recess 1121 is located in the center of the base plate main body 1100 and the protrusions 1122 are located on both sides of the recess. The angle between the top surface of the recess 1121 and the horizontal plane is smaller than the angle between the top 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 compatible with the drive wheels. By providing the recess 1121 at the center of the base plate main body 1100, it is possible to prevent the automatic cleaning device from being obstructed or scraped by the surface of the base plate main body 1100 when climbing up or off 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 of the base plate body 1100 along the first direction. 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, which 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 up and off the pile smoothly.

[0089] In some embodiments, the main body base 6000 has an upper surface referred to as a first upper surface. When the main body base 6000 is placed on a horizontal surface, the upper surface of the main body base 6000 is inclined at a predetermined angle relative to the horizontal plane, and the inclination coefficient corresponding to the predetermined angle is referred to as a first inclination coefficient. Similarly, the base plate main body 1100 has an upper surface referred to as a second upper surface. When the base plate main body 1100 is placed on a horizontal surface, the upper surface of the base plate main body 1100 is inclined at a predetermined angle relative to the horizontal plane, and the inclination coefficient corresponding to the predetermined angle is referred to as a second inclination coefficient. In some embodiments, the base plate main 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 relative 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 required for 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 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 to connect and seal the dust collection port 6100 and the dust outlet of the automatic cleaning device and prevent dust leakage. The dust collection port 6100 is located on the top surface of the main body base 6000, and is located approximately at the edge 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 base plate body 1100, approximately at the edge of the connection between the base plate body 1100 and the body base 6000. In some embodiments, the lifting structure 1300 is provided in the recess 1121 of the base plate body 1100. The lifting structure 1300 is configured to press the cleaning module on the bottom of the automatic cleaning device when the automatic cleaning device moves in the reverse direction (with the front side of the body facing the first direction X, which is outside the self-cleaning dust collecting sheet body 2000) toward the self-cleaning dust collecting sheet bottom plate 1000, causing the cleaning module to move toward the inside of the automatic cleaning device, for example, to be pushed into the automatic cleaning device.

[0092] During the process in which the automatic cleaning device retreats to the self-cleaning dust collecting sheet bottom plate 1000 along the opposite direction of 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 top surface of the base plate body 1100. When the automatic cleaning device retreats to the self-cleaning dust collecting sheet base plate 1000 in the direction opposite to the first 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 brought into contact with 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. As the cleaning module moves inward (e.g., pushed into the automatic cleaning device by the lifting structure 1300), and then continues to retreat in the opposite direction to first direction X, the frame of the cleaning module passes above the dust collection port 6100 and gradually disengages from the lifting structure 1300. During this process, even if the cleaning module completely disengages from the lifting structure 1300, part or all of the cleaning module remains above the dust collection port 6100, allowing the cleaning module to pass through smoothly while remaining in close contact with the dust collection port 6100. After the cleaning module completely passes through the dust collection port 6100, it gradually recovers under the force of gravity to its original state before being pressed by the lifting structure 1300, i.e., at least part of the cleaning module protrudes in a direction away from the automatic cleaning device. In this way, the cleaning module descends a certain height (e.g., 8 mm) under the force 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 base 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-shaped 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 this order along a first direction X, and the first inclined surface 1311, the first top surface 1313, and the second inclined surface 1312 are abutted against each other in this order in the first direction X.

[0097] The acute angle between the first inclined surface 1311 and the upper surface of the base plate body 1100 where the first inclined surface 1311 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 base plate body 1100 where the second inclined surface 1312 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 retracts onto the base plate body 1100 in the direction opposite to the first direction X, the automatic cleaning device is gently pressed and can descend quickly. 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 retracts onto the base plate body 1100 in the direction opposite to the first direction X, the cleaning module on the bottom of the automatic cleaning device is 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 can descend quickly under the action of gravity after it is released from the lifting structure 1300.

[0098] 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 when pressing the cleaning module against 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 reduces the frictional resistance between the frame of the cleaning module and the wedge-shaped member 1310, reduces wear between components, and extends the service life of each component.

[0100] In some embodiments, a portion of the roller 1320 may be embedded within the wedge-shaped member 1310, allowing for a smooth transition from sliding contact to rolling contact between the lifting structure 1300 and the frame of the cleaning module. In some embodiments, the roller 1320 may be removably connected to the wedge-shaped member 1310 to facilitate replacement of the roller 1320.

[0101] In some embodiments, the number of lifting structures 1300 is at least two, and the at least two lifting structures 1300 are arranged opposite each other in the second direction Y, which is perpendicular to the first direction X. When the automatic cleaning device retracts into the base plate body 1100 in the direction opposite to the first direction X, the at least two lifting structures 1300 abut against the frame of the cleaning module, respectively, to lift the cleaning module uniformly by 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 shifting in the second direction Y due to uneven force.

[0102] In some embodiments, the number of lifting structures 1300 is two, the two lifting structures 1300 are arranged opposite 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 collection opening 6100 in the second direction Y or is slightly larger than the width of the dust collection opening 6100 in the second direction Y 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 1400, which may be a slope and is provided on the surface of the bottom plate body 1100. Specifically, the slope 1400 may be provided at the edge of the connection between the bottom plate body 1100 and the body base 6000, approximately in front of the dust collection opening 6100 and on the central axis of the bottom plate body 1100. In some embodiments, the number of lifting structures 1300 is two, which are provided opposite each other in the second direction Y, and the slope 1400 is located substantially in the middle of the two lifting structures 1300. By providing the slope 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 collection opening 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 Figure 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 of the base plate body 1100 and providing the ramp 1400 and the lifting structure 1300 in the recess 1121, it is possible to prevent the automatic cleaning device from being obstructed by or scraped against the surface of the base plate body 1100 when climbing up or down the pile.

[0105] In some embodiments, the lifting structure 1300 is provided in the recess 1121 of the base plate body 1100, and the height of the lifting structure 1300 is greater than the protrusion 1122, effectively pressing the cleaning module on the bottom 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 disposed 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 will not 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 climbing up or leaving the pile.

[0107] In some embodiments, the lifting structure 1300 has a predetermined distance from the stop end of the base plate body 1100, so that when the automatic cleaning device enters the self-cleaning dust collecting sheet base plate 1000 from behind, if the drive wheels of the automatic cleaning device do not enter the stop end of the base plate body 1100, the lifting structure 1300 will not come into contact with the cleaning module. This is because the retraction force of the automatic cleaning device is relatively small before the drive wheels of the automatic cleaning device contact the anti-skid structure 1123 at the start end. If the lifting structure 1300 comes into contact with the cleaning module (such as a mop cloth bracket) at this time, it may hinder the automatic cleaning device from climbing the pile, leading to pile climbing failure. Correspondingly, when the drive 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, at which 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 including 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 have a lifting structure on the base plate body, which can avoid the phenomenon of the cleaning module being scraped or stuck when the automatic cleaning device is climbing up or leaving the pile, and thus can improve the success rate of the automatic cleaning device climbing up or leaving the pile.

[0110] In the related art, the air duct structure of the self-cleaning dust collecting sheet is usually complicated, occupying more physical space, making the self-cleaning dust collecting sheet appear bulky. Furthermore, the complicated air duct structure also reduces the dust collection effect to a certain extent, making it difficult to suck all the dust in the dust box into the dust collection chamber of the self-cleaning dust collecting sheet.

[0111] Therefore, the embodiments of the present disclosure provide a self-cleaning dust collecting sheet, which 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 below. 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 Figs. 15 and 16 are diagrams specifically showing the air duct structure of the self-cleaning dust collecting sheet and the direction of airflow in the air duct in the dust collecting state.

[0113] 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 main 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 main body 2000. Specifically, the self-cleaning dust collecting sheet bottom plate 1000 is detachably or non-detachably connected to a main body base 6000 below the self-cleaning dust collecting sheet main body 2000. The detachable connection method facilitates transportation and maintenance.

[0114] The self-cleaning dust collecting sheet body 2000 is configured to collect dust 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 collection bin 3000, a clean water tank 4000, and a dirty water tank 5000 arranged side by side. Specifically, as shown in Fig. 2, the self-cleaning dust collecting sheet body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 opens upward and forward and is provided at the top of the self-cleaning dust collecting sheet body 2000. 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 opens upward and forward and is located 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 forms 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 easy to attach and detach the dirty water tank 5000, the clean water tank 4000, and the dust collection cover 2800.

[0115] A body base 6000 is located 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 self-cleaning dust collecting sheet bottom plate 1000. Specifically, the self-cleaning dust collecting sheet bottom plate 1000 and the body base 6000 are arranged sequentially along a second direction, which is opposite to the arrow on the front-rear axis X.

[0116] As shown in FIG. 14 , the dust collection opening 6100 is provided on the main body base 6000 and is located approximately at the edge of the connection between the main body base 6000 and the self-cleaning dust collecting sheet bottom plate 1000. The dust collection opening 6100 is configured to connect to the dust outlet of the automatic cleaning device, so that dust in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collecting sheet main body 2000 through the dust collection opening 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection opening 6100 to seal the dust collection opening 6100 and the dust outlet of the automatic cleaning device after connection, thereby preventing dust leakage. The dust collection opening 6100 extends substantially along a first direction, which is opposite to the arrow of the horizontal axis Y and is substantially perpendicular to the second direction. The first direction is also the longitudinal direction of the dust collection opening 6100, and the extension distance of the dust collection opening 6100 in the first direction may be referred to as length L1. The dust collection opening 6100 extends along the first direction and also along a second direction, which is the width direction of the dust collection opening 6100, and the extension distance of the dust collection opening 6100 in the second direction may be referred to as 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 main 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 fluid in the wet cleaning module of the automatic cleaning device, and / or to collect dust removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module, and to facilitate subsequent disposal of the dust and wastewater. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100. The cleaning groove 6200 extends along the second direction to the lower part of the self-cleaning dust collecting sheet main body 2000, and a sidewall may be formed between the self-cleaning dust collecting sheet main 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 which 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 generated within the dust collection bin 3000, and dust within the dust box 300 is sucked into the dust collection bag through the dust collection port 6100 and the air duct 2500. The air duct 2500 is further divided into a main body air duct 2510 and a base air duct 2520 based on its location. The base air duct 2520 is located substantially at the position indicated by the dashed frame in the lower right corner of FIG. 15 , and the main body air duct 2510 is located substantially at the position indicated by the dashed frame in the upper right corner of FIG. 15 . In Figures 15 and 16, solid arrows indicate the trajectories of dust driven by airflow in the base air duct 2520 and main body air duct 2510.

[0119] Specifically, the base air duct 2520 is located inside the main body base 6000, and has a substantially 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 in a first direction to approximately the edge of the main body base 6000, and then extends in a second direction to the main body air duct 2510. In some embodiments, one longitudinal end of the base air duct 2520 communicates with the dust collection port 6100, so that the airflow and the dust driven thereby flows directly out from the longitudinal end of the dust collection port 6100 and then proceeds in a substantially straight line, thereby reducing the resistance of the airflow when it flows out of the dust collection port 6100. In some embodiments, the position at which the base air duct 2520 extends in the second direction is between the edge of the cleaning groove 6200 and the edge of the main body base 6000, which makes full use of the limited space in the main body base 6000 and can 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 an 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 dust in the dust box 300 to pass through the base air duct 2520, avoiding clogging of the base air duct 2520 and improving the dust collection effect. In some embodiments, 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 through the base air duct 2520 gentler and preventing sudden changes in flow velocity.Similarly, in the base air duct 2520, the curved portion extending along the second direction and the curved portion extending upward of the main body 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, with one end of the main air duct 2510 communicating with the base air duct 2520 and the other end leading to the dust collecting chamber 2100, so that 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. This design of the main air duct 2510 makes full use of the space between the self-cleaning dust collecting sheet body 2000 and the cleaning groove 6200, making the structure more compact. In some embodiments, the width of the main air duct 2510 is larger than the width of the base air duct 2520, and by appropriately adjusting the width relationship between the main air duct 2510 and the base air duct 2520, the air flow rate in the base air duct 2520 can be increased, making it easier for dust in the dust box 300 to pass through the base air duct 2520, avoiding clogging of the base air duct 2520, and improving the dust collection effect.

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

[0122] The present disclosure further provides an automatic cleaning device and a dust collection system including 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 the side wall of the dust box 300 in the first extension direction facing the base air duct 2520, the dust inlet 310 is provided on the side wall of the dust box 300 facing the self-cleaning dust collecting sheet main body 2000, and the dust inlet 310 is connected to the dust outlet of the automatic cleaning device.

[0124] Under dust collection conditions, the air inlet 320 of the dust box 300 is opened, and the first fan on the self-cleaning dust collection sheet starts operating, sucking out gas from the dust collection chamber 2100 and the air duct 2500. This reduces the air pressure in the dust collection chamber 2100 and the air duct 2500, allowing airflow to form a U-shaped passage between the air inlet 320 of the dust box 300, the dust inlet 310, the dust outlet of the automatic cleaning device, the dust collection port 6100 of the self-cleaning dust collection sheet, and the air duct 2500. The airflow lifts up the dust in the dust box 300, which is then sucked into the dust collection chamber 2100. The U-shaped passage provides an optimal flow path for airflow. The U-shaped passage design allows for smoother airflow, allowing the dust in the dust box to easily exit the dust box and enter the air duct and into the dust collection bin.

[0125] According to the self-cleaning dust collecting sheet and dust collection 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 can be made smaller, the air duct of the self-cleaning dust collecting sheet becomes smoother, the structure is compact, and the dust collection efficiency of the automatic cleaning device can be further improved.

The present disclosure has been described in detail with reference to the above embodiments. However, those skilled in the art can still modify the technical solutions described in each of the above embodiments or substitute some of the technical features with equivalents, and it should be understood that these modifications and substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each of the embodiments of the present disclosure.
