[0034] Compared to the prior art, the embodiments of this disclosure have the following technical advantages.

[0035] By providing a dust collection chamber for housing the dust collection cover and a water storage chamber for housing the water storage tank side-by-side at the top of the self-cleaning dust collection sheet body, the vertical space required for the dust collection sheet is saved. When sufficient volume is ensured for the dust collection and water storage chambers, the dust collection sheet body does not become too tall, resulting in an unstable center of gravity. The air duct, designed from bottom to top, reduces the complexity of the airflow path, improving dust collection efficiency. Sleeved into the dust collection chamber, the suction force from the fan during the dust collection process ensures a tighter seal against the cavity, further enhancing the sealing effect. Exposing the water storage tank and dust collection cover to the water storage and dust collection chambers allows the user to visually inspect the internal conditions of the tank and cover through the exposed parts, improving the user experience. Furthermore, compared to a design method where the water storage tank and dust collection cover are all placed inside the water storage chamber and dust collection chamber, the exposed design allows the user to remove the water storage tank and dust collection cover without having to lift them above the highest point of the cavity and then move them horizontally, reducing the user's lifting stroke and making it easier for the user to remove the water storage tank and dust collection cover from inside the cavity.

[0039] To further clarify the purpose, technical solutions, and advantages of this disclosure, the disclosure will be described in more detail below with reference to the accompanying drawings, although obviously the embodiments described are only a selection of the embodiments of this disclosure, not all of them. Any other embodiments that a person skilled in the art could obtain without creative work based on the embodiments of this disclosure are all covered by this disclosure.

[0040] The terms used in the embodiments of this disclosure are used solely for the purpose of describing specific embodiments and are not intended to limit the disclosure. The singular forms “one,” “the said,” and “the said” as used in the embodiments of this disclosure and the appended claims are also intended to include plural forms, and “plural” generally includes at least two unless the context explicitly indicates otherwise.

[0041] The terms "and / or" as used herein merely describe the relationship between related objects, and there are three possible 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 preceding and succeeding related objects are in an "or" relationship.

[0042] In the embodiments of this disclosure, terms such as First, Second, Third, etc., may be used for illustrative purposes, but it should be understood that these terms should not be used as a limiting factor. These terms are used solely for distinction. For example, the First may also be called the Second, and similarly, the Second may also be called the First, as long as it does not deviate from the scope of the embodiments of this disclosure.

[0043] Furthermore, the terms “includes,” “equipped with,” or any other variations thereof are intended to cover non-exclusive inclusion, and it should be noted that a product or apparatus containing a set of elements includes not only those elements but also other elements explicitly listed, or elements specific to those products or apparatus. Unless further limited, an element defined by the expression “includes…” does not exclude the presence of other identical elements in a product or apparatus containing such element.

[0044] Selective embodiments of this disclosure will be described in detail below with reference to the attached drawings.

[0045] In related technologies, the structure of self-cleaning dust collection sheets is usually complex, the water tank is located inside the complex hood cover of the self-cleaning dust collection sheet making it difficult to fill and use, the water tank connection port is formed at the bottom of the water tank so the water in the tank is prone to overflowing and there is a very high possibility that the components inside the self-cleaning dust collection sheet will be damaged, and furthermore the air duct of the self-cleaning dust collection sheet is also too complex so that dust does not easily enter the dust collection bin from the dust box.

[0046] Therefore, the embodiments of this disclosure provide a self-cleaning dust collection sheet, and by exposing the water tank and dust collection cover to the outside of the self-cleaning dust collection sheet body, installation and use by the user are made easier. At the same time, by providing the water inlet at the top of the self-cleaning dust collection sheet body, water is less likely to overflow from the water tank, and by providing the air duct directly on the side wall of the self-cleaning dust collection sheet body, the path of the air duct is reduced, and dust collection efficiency is improved. Specifically, as an example of the self-cleaning dust collection sheet provided by the embodiments of this disclosure, Figure 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet, and Figure 2 is a schematic diagram showing the structure of the self-cleaning dust collection sheet body after the wastewater tank, clean water tank and dust collection cover of this disclosure have been removed.

[0047] To more clearly explain the behavior of the self-cleaning dust collection sheet, the following directions are defined. Specifically, the self-cleaning dust collection sheet is defined by three mutually perpendicular axes: the lateral axis Y, the front-to-back axis X, and the central vertical axis Z. The direction opposite to the arrow along the front-to-back axis X, i.e., the direction in which the automatic cleaning device enters the self-cleaning dust collection sheet, is defined as "rear," and the direction of the arrow along the front-to-back axis X, i.e., the direction in which the automatic cleaning device leaves the self-cleaning dust collection sheet, is defined as "front." The lateral axis Y is essentially the direction along the width of the self-cleaning dust collection sheet body. The vertical axis Z is the direction extending upward along the bottom surface of the self-cleaning dust collection sheet.

[0048] As shown in Figure 1, the direction in which the bottom plate of the self-cleaning dust collection sheet protrudes from the main body of the self-cleaning dust collection sheet is forward, the direction toward the rear wall of the main body of the self-cleaning dust collection sheet is backward, the dust collection bin 3000 is on the left side of the self-cleaning dust collection sheet, the clean water tank 4000 is on the right side of the dust collection bin 3000, and the wastewater tank 5000 is on the right side of the clean water tank 4000.

[0049] As shown in Figure 1, the self-cleaning dust collection sheet provided by this embodiment includes a self-cleaning dust collection sheet base plate 1000, a self-cleaning dust collection sheet body 2000, a dust collection cover 2800 provided alongside the self-cleaning dust collection sheet body 2000, a clean water tank 4000, and a wastewater tank 5000, wherein, in order to facilitate the transport and maintenance of the self-cleaning dust collection sheet base plate 1000 and the self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet base plate 1000 is detachably or non-detachably connected to the self-cleaning dust collection sheet body 2000. As shown in Figure 2, the self-cleaning dust collection sheet body 2000 includes a water storage chamber 2700, a dust collection chamber 2100, and an air duct 2500. The water storage chamber 2700 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000. The water storage chamber includes a clean water chamber 2400 for housing a clean water tank 4000 and a wastewater chamber 2300 for housing a wastewater tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000, alongside the water storage chamber. The dust collection chamber 2100 constitutes a dust collection bin 3000 for housing a dust collection cover 2800. The design of the water storage chamber 2700 and dust collection chamber 2100, which face upward and forward, facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800. The wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800 are all assembled to the self-cleaning dust collection sheet body 2000 from the front and upward. This structural design is in line with the user's usage habits, and furthermore, the upward and forward-facing design makes it convenient for the daily maintenance of the components inside the water storage chamber 2700 and the dust collection chamber 2100.

[0050] The self-cleaning dust collection sheet body 2000 further includes an air duct 2500 and a body base 6000. The air duct 2500 is provided on the self-cleaning dust collection sheet body 2000 from bottom to top, and the air duct connects the dust collection port and dust collection chamber 2100 located on the base of the self-cleaning dust collection sheet body 2000. This makes the internal air passage of the dust collection pile very simple and significantly improves dust collection efficiency.

[0051] In one embodiment, at least a portion of the air duct 2500 is provided on the side wall of the self-cleaning dust collection sheet body 2000, and the air duct 2500 connects the main body base 6000 at the bottom of the self-cleaning dust collection 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 main body base 6000 and enters the dust collection chamber 2100 via the air duct 2500. The self-cleaning dust collection sheet body 2000 is configured to collect dust in the dust box of an automatic cleaning device. The main body base 6000 of the self-cleaning dust collection sheet has a dust collection port 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 collection sheet body 2000 through the dust collection port 6100. A sealing rubber gasket is further provided around the dust collection port 6100, connecting and sealing the dust collection port 6100 to the dust outlet of the automatic cleaning device, ensuring dust collection effectiveness while simultaneously preventing waste leakage.

[0052] As shown in Figure 2, the water storage chamber 2700 and the dust collection chamber 2100 are formed by being surrounded by the rear wall, front wall and multiple side walls of the self-cleaning dust collection sheet body 2000. The rear wall and front wall of the water storage chamber 2700 and the dust collection chamber 2100 are coplanar, and are coplanar with one side wall. Here, the height of the rear wall of the self-cleaning dust collection sheet body 2000 is greater than the height of the front wall of the self-cleaning dust collection sheet body 2000, the side walls of the self-cleaning dust collection sheet 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 body 2000 have an arc-shaped structure. The design of the water storage chamber 2700 and dust collection chamber 2100 facing upward and forward facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800. Here, the arc-shaped structure ensures the stability and aesthetic appeal 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.

[0053] The water storage chamber 2700 is used to house water storage tanks (including a wastewater tank 5000 and a clean water tank 4000), and includes a boss 2600 that is in close contact with the rear wall of the water storage chamber 2700 and extends upward along the bottom of the water storage chamber 2700 to be slightly lower than the height of the rear wall of the water storage chamber, with a plurality of projection openings provided on the top of the boss, the projection openings being made of a soft rubber material but not limited to it, and the projection openings being configured to connect to a wastewater tank 5000 or a clean water tank 4000 assembled in a corresponding position. Here, the water storage chamber 2700 includes a vertically extending partition plate 2710, and the water storage chamber 2700 is divided into two parts, one of which is a wastewater chamber 2300 for housing the wastewater tank 5000 and the other part is a clean water chamber 2400 for housing the clean water tank 4000. The upper part of the boss may be the top of the boss, or it may be a boss side wall that is higher than the highest water level line of the clean water tank and wastewater tank in the assembled state; however, it is not limited to this.

[0054] In the prior art, the water outlet or water inlet of a water tank is usually located at the bottom of the water tank, and when the water tank is lifted, the gravity of the water pushes the switch of the water outlet downward, which prevents water leakage. However, in the usual case, if the switch gets stuck or if there is little water in the water tank, the sealing effect of the switch is insufficient, and in this case, some water leaks out from the water outlet or water inlet during the process of lifting the water tank, leading to damage to the external components connected thereto. In some embodiments, the projection opening includes an air pump port 2610 and a sewage tank connection port 2620, and is provided corresponding to the top end of the boss 2600 at the assembly position of the sewage tank 5000, and the air pump sucks air from inside the sewage tank 5000 through the air pump port 2610, and because the sewage tank 5000 has a sealed structure, negative pressure is formed inside during the air sucking process, and sewage in the cleaning groove is sucked into the sewage tank 5000 through the sewage pipe and the sewage 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. Under the action of the peristaltic pump, the clean water in the clean water tank 4000 flows through the clean water tank connection port 2630 onto the squeegee member in the cleaning groove, cleaning the cleaning head of the automatic cleaning device. The air pump port 2610, the wastewater tank connection port 2620, and the clean water tank connection port 2630 are provided at the top end of the boss 2600 to prevent water from overflowing from the water tank and flowing into the clean water chamber or wastewater chamber during the replacement process of the clean water tank or wastewater tank. The air pump port 2610, wastewater tank connection port 2620, and clean water tank connection port 2630, along with the sealed connections at the top of the wastewater tank 5000 and clean water tank 4000, provide greater operational convenience compared to connecting at the bottom of the clean water chamber or wastewater chamber.

[0055] The self-cleaning dust collection sheet further includes a wastewater tank 5000 and a clean water tank 4000 arranged side by side in the water storage chamber, and a dust collection cover 2800 arranged side by side in the dust collection chamber 2100, wherein the top surfaces of the wastewater tank, the clean water tank, and the dust collection cover are substantially flush, and the front surfaces are substantially flush. After the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800 are assembled to the self-cleaning dust collection sheet body 2000, a flat arrangement structure is formed, which makes attachment and detachment easy and use, and on the other hand, the external shape is flat and aesthetically pleasing, improving the user experience.

[0056] When a self-cleaning dust collection sheet is used for a long period of time, the protruding openings become contaminated by the wastewater used when cleaning the cleaning components, and it is unavoidable that dirt will remain. With the above installation, the protruding openings on the boss 2600 have an open structure with respect to the front wall and also have an open structure with respect to the side walls, allowing arms and cleaning tools to contact the protruding openings from any angle, and allowing users to easily clean the dirt accumulated around the protruding openings.

[0057] 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 collection sheet body, and a portion of the tank bodies of the wastewater tank and the clean water tank are located outside the water storage chamber. When the dust collection cover 2800 is assembled in the dust collection chamber 2100, the top surface of the dust collection cover is higher than the rear wall of the self-cleaning dust collection sheet body, and most of the dust collection cover is located outside the dust collection chamber. The above design reduces the amount of material used for the self-cleaning dust collection sheet body. Since the wastewater tank, clean water tank, and the top of the dust collection cover are exposed to the outside of the dust collection chamber, people can easily lift the wastewater tank, clean water tank, and the top of the dust collection cover using the handles provided on top of the dust collection cover. This allows for easy operation of the wastewater tank, clean water tank, and dust collection chamber, and also provides the technical benefit of an aesthetically pleasing design. At the same time, the top of the self-cleaning dust collection sheet body is designed with a low front wall and a high rear wall, so the upper positions of the wastewater tank, clean water tank, and the front of the dust collection cover are also exposed to the outside of the dust collection chamber. This allows people to easily observe the water levels in the transparent wastewater tank and clean water tank and the conditions inside the dust collection chamber, enabling timely and appropriate operation of the wastewater tank, clean water tank, and dust collection chamber.

[0058] 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 chamber, completely sealing the inside of the dust collection bin and contributing to improved dust collection efficiency.

[0059] A cleaning chamber is formed between the lower part of the self-cleaning dust collection sheet body 2000 and the body base 6000, and the cleaning chamber is used to house the automatic cleaning device when it returns to the self-cleaning dust collection sheet for maintenance. A cleaning groove 6200 is provided on the body base 6000 of the self-cleaning dust collection sheet, and is configured to clean the cleaning members on the automatic cleaning device through the cleaning groove after the automatic cleaning device has been fitted into the cleaning chamber.

[0060] After the automatic cleaning device, such as a sweeping robot, has finished cleaning and returned to the self-cleaning dust collection sheet, the automatic cleaning device moves along the inclined surface of the self-cleaning dust collection sheet bottom plate 1000 to the main body base 6000, the dust outlet of the automatic cleaning device is connected to the dust collection port 6100 on the main body base 6000, and the debris in the dust box of the automatic cleaning device is transferred to the dust collection bin 3000 of the self-cleaning dust collection sheet main body 2000.

[0061] In some embodiments, the main body base 6000 and the main body 2000 are formed as a single, non-detachable unit, and the main body base 6000 further includes a dust collection air passage, which is provided within the main body base 6000 and configured to collect dust from within the automatic cleaning device. The air inlet of the dust collection air passage is a dust collection port, and the air outlet of the dust collection air passage communicates with a dust collection chamber 2100 via an air duct 2500.

[0062] The self-cleaning dust collection sheet body has a dust collection chamber for housing the dust collection cover and a water storage chamber for housing the water storage tank side by side at its top. This saves vertical space in the dust collection sheet, and when sufficient volume is secured in the dust collection chamber and water storage chamber, the dust collection sheet body does not become too tall and the center of gravity does not become unstable. The dust collection cover is sleeved over the dust collection chamber, and the suction force from the fan during the dust collection process makes it tighter in contact with the cavity, further improving the sealing effect. The water storage tank and dust collection cover are exposed to the outside of the water storage chamber and dust collection chamber, allowing the user to visually observe the internal condition of the tank body and cover body through the exposed parts, improving the user experience. Compared to designs where the water storage tank and dust collection cover are all located inside the water storage chamber and dust collection chamber, the exposed design eliminates the need for the user to lift both over the highest point of the cavity and then move them horizontally to remove them, reducing the user's lifting stroke and allowing the user to easily remove the water storage tank and dust collection cover from inside the cavity.

[0063] In related technologies, the structure of self-cleaning dust collection sheets is usually complex, the water tank is located inside the complex hood cover of the self-cleaning dust collection sheet, making it difficult to fill and use, and because the water tank connection port is formed at the bottom of the water tank, the water in the tank is prone to overflowing, which greatly increases the possibility of damage to the components inside the self-cleaning dust collection sheet.

[0064] Therefore, the embodiments of this disclosure provide a self-cleaning dust collection sheet, in which at least a portion of the water tank is exposed to the outside of the self-cleaning dust collection sheet body, making it easy for the user to attach and detach, and by providing the water inlet of the water tank at the top of the water tank, the liquid in the water tank is less likely to overflow, and damage to electronic components due to overflowing liquid can be avoided. Similar structures have similar technical effects, some of which are not described here.

[0065] Specifically, the self-cleaning dust collection sheet provided by the embodiments of this disclosure is, for example, shown in Figure 1, a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet; Figure 2, a schematic diagram illustrating the structure of the self-cleaning dust collection sheet body after removing the wastewater tank, clean water tank, and dust collection cover of this disclosure; and Figures 3 to 5, schematic diagrams showing the water storage tank related to the self-cleaning dust collection sheet of this disclosure from different viewing angles.

[0066] As shown in Figure 1, the self-cleaning dust collection sheet provided by this embodiment includes a self-cleaning dust collection sheet base plate 1000, a self-cleaning dust collection sheet body 2000, and a water storage tank 7000. Here, in order to facilitate the transport and maintenance of the self-cleaning dust collection sheet base plate 1000 and the self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet base plate 1000 is detachably or non-detachably connected to the self-cleaning dust collection sheet body 2000, and the water storage tank 7000 is assembled to the top end of the self-cleaning dust collection sheet body 2000.

[0067] As shown in Figure 2, the self-cleaning dust collection 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 collection sheet body 2000. The water storage chamber 2700 is configured to house a water storage tank 7000. The water storage tank 7000 may be a clean water tank 4000 or a wastewater tank 5000. There may be multiple water storage tanks 7000. In some embodiments, the self-cleaning dust collection sheet body 2000 includes two water storage tanks 7000, which are a clean water tank 4000 and a wastewater tank 5000, and accordingly the water storage chamber includes a clean water chamber 2400 for housing the clean water tank 4000 and a wastewater chamber 2300 for housing the wastewater tank 5000. The water storage chamber 2700 is designed to be positioned upward and forward, and the water storage tank 7000 is assembled to the self-cleaning dust collection sheet body 2000 from the front and upward direction. This assembly method better suits the user's usage habits and facilitates the attachment and detachment of the water storage tank 7000. Furthermore, the upward and forward design facilitates routine maintenance of the components inside the water storage chamber 2700.

[0068] The water storage chamber 2700 is formed by being surrounded by the rear wall, front wall, and multiple side walls of the self-cleaning dust collection sheet body 2000, where the height of the rear wall of the self-cleaning dust collection sheet body 2000 is greater than the height of the front wall of the self-cleaning dust collection sheet body 2000, the side walls of the self-cleaning dust collection sheet body 2000 connect the rear wall and the front wall, and the end faces of the side walls of the self-cleaning dust collection sheet body 2000 have an arc-shaped structure. The arc-shaped structure ensures the stability and aesthetic appeal of the water storage tank 7000 attached to the water storage chamber 2700.

[0069] The water storage chamber 2700 further includes a rear wall in close contact with the water storage chamber 2700, and a boss 2600 extending upward from the bottom of the water storage chamber 2700 to a height slightly lower than the height of the rear wall of the water storage chamber. The height of the boss 2600 is higher than the height of the highest water level line of the water storage tank 7000, and when the water storage tank 7000 is assembled in the water storage chamber 2700, the boss 2600 supports the water tank projection 7220 of the water storage tank 7000.

[0070] Multiple protruding openings are provided on the top of the boss 2600, and these protruding openings are used to connect to a water storage tank 7000 assembled at a corresponding position. Specifically, these protruding openings are used to connect to a sewage outlet or a clean water outlet provided on the water storage tank 7000.

[0071] In some embodiments, the projection opening includes an air pump connection port 2610 and a sewage tank connection port 2620, which are provided corresponding to the top end of the boss 2600 at the assembly position of the sewage tank 5000. The air pump draws air from inside the sewage tank 5000 through the air pump connection port 2610. Because the sewage tank 5000 is a sealed structure, a negative pressure is formed inside during the air extraction process, and the sewage in the cleaning groove is drawn into the sewage tank 5000 through the sewage pipe and the sewage tank connection port 2620.

[0072] In some embodiments, the projection 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 via the clean water tank connection port 2630 under the action of a peristaltic pump to clean the cleaning head of the automatic cleaning device.

[0073] The air pump port 2610, wastewater tank connection port 2620, and clean water tank connection port 2630 are located at the top of boss 2600, preventing water from overflowing from the clean water tank or wastewater tank and flowing into the clean water chamber or wastewater chamber during the replacement process of the clean water tank or wastewater tank. The seal connection between the air pump port 2610, wastewater tank connection port 2620, and clean water tank connection port 2630 and the top of wastewater tank 5000 and clean water tank 4000 is more convenient to operate than a bottom-end connection of the clean water chamber or wastewater chamber.

[0074] When a self-cleaning dust collection sheet is used for a long period of time, the protruding openings become contaminated by the wastewater used when cleaning the cleaning components, and it is unavoidable that dirt will remain. With the above installation, the protruding openings on the boss 2600 have an open structure with respect to the front wall and also have an open structure with respect to the side walls, allowing arms and cleaning tools to contact the protruding openings from any angle, and allowing users to easily clean the dirt accumulated around the protruding openings.

[0075] In some embodiments, a plurality of soft rubber protrusions 2640 may be provided on the top of the boss 2600, and these soft rubber protrusions 2640 are adapted to correspond to pits 7221 provided on the lower surface of the water tank projection 7220 of the water storage tank 7000. When the water storage tank 7000 is assembled into the water storage chamber 2700, the soft rubber protrusions 2640 on the water storage chamber 2700 are limited to the pits 7221 on the water storage tank 7000. The specific number of soft rubber protrusions 2640 may be set according to the actual situation, and the soft rubber protrusions 2640 may be distributed symmetrically on the top of the boss 2600. For example, in one embodiment, there are four soft rubber protrusions 2640, which are distributed substantially uniformly on the top of the boss 2600. The cooperation and constraints of the soft rubber protrusions 2640 and the pits 7221 allow for more precise positioning of the water storage tank 7000 within the water storage chamber 2700, thus preventing misalignment of the water storage tank 7000.

[0076] The water storage chamber 2700 may further include a vertically extending partition plate 2710, which divides the water storage chamber 2700 into two parts: one part is a wastewater chamber 2300 for housing a wastewater tank 5000, and the other part is a clean water chamber 2400 for housing a clean water tank 4000. At least one vibration damping pad 2711 is provided at the top of the partition plate 2710, which is configured to support the handle when it falls and to reduce the vibration of the handle. At least one limiting projection (not shown) is provided on each side of the partition plate 2710, and at least one limiting recess 7120 is provided in the side walls of the wastewater tank and the clean water tank facing the partition plate 2710, which are fitted to the limiting projection, and after the wastewater tank and the clean water tank are assembled into the wastewater chamber and the clean water chamber, the limiting projection fits with the limiting recess to restrict movement.

[0077] The water storage tank 7000 is detachably assembled to the top of the self-cleaning dust collection sheet body 2000, specifically, the water storage tank 7000 is detachably assembled within the water storage chamber 2700. The detachable assembly of the water storage tank 7000 and the upward and forward design of the water storage chamber 2700 make it very easy to attach and detach the water storage tank 7000, which is convenient for the user to perform routine liquid replacement in the water storage tank 7000. The water storage tank 7000 may be made of a transparent material to allow observation of the liquid level inside the water storage tank 7000.

[0078] In some embodiments, when the water storage tank 7000 is assembled in the water storage chamber 2700, the top surface of the water storage tank 7000 may be higher than the rear wall of the water storage chamber 2700, and the majority of the water storage tank 7000 body may be located outside the water storage chamber 2700. This design further optimizes the attachment and detachment of the water storage tank 7000, is convenient for the user to perform routine liquid replacement in the water storage tank 7000, and reduces the amount of material used for the self-cleaning dust collection sheet body 2000. Furthermore, the top of the self-cleaning dust collection sheet body 2000 is designed with a lower front wall and a higher rear wall, and the front and upper part of the water storage chamber 2700 is also exposed to the outside of the cavity, allowing the user to easily observe the water level in the transparent water storage chamber 2700 and perform corresponding operations on the water storage chamber 2700.

[0079] The water storage tank 7000 may be a clean water tank 4000 or a wastewater tank 5000. There may be multiple water storage tanks 7000. In some embodiments, the self-cleaning dust collection sheet body 2000 includes two water storage tanks 7000, which are a clean water tank 4000 and a wastewater tank 5000, respectively. The wastewater tank 5000 and the clean water tank 4000 are arranged side by side on the water storage chamber 2700, and the top surfaces of the wastewater tank 5000 and the clean water tank 4000 are substantially flush, and the front surfaces are substantially flush. After the wastewater tank 5000 and the clean water tank 4000 are assembled on the self-cleaning dust collection sheet body 2000, a flat arrangement structure is formed, which on the one hand makes attachment and detachment and use easier, and on the other hand, the external shape is flat and aesthetically pleasing, improving the user experience.

[0080] The water storage tank 7000 has an opening for the inflow or outflow of liquid. The opening is located at the top of the tank body, and its height is higher than the highest water level line 7111 of the water storage tank 7000. If the water storage tank 7000 is a clean water tank 4000, the opening is a clean water outlet; if the water storage tank 7000 is a wastewater tank 5000, the opening is a wastewater outlet. Having the opening higher than the highest water level line of the water storage tank 7000 prevents the liquid in the water storage tank 7000 from overflowing from the water tank, particularly preventing liquid spillage during the water tank replacement process. Furthermore, damage to electronic components due to spilled liquid can be avoided.

[0081] Referring together to Figures 3 to 5, the water storage tank 7000 includes a water tank housing 7100 and a water tank top cover 7200, the water tank top cover 7200 substantially covers the water tank housing 7100, the water tank housing 7100 includes a water tank body 7130 and a water tank projection 7140, the water tank top cover 7200 together with the water tank housing 7100 form a cavity, the water tank projection 7140 protrudes from the water tank body 7130, and the water storage tank has a substantially L-shaped structure.

[0082] The water tank housing 7100 is used to store liquid. The side wall of the water tank housing 7100 includes at least one recess extending upward along the bottom of the water tank housing, the recess being limited in combination with a projection in the water storage chamber 2700. In some specific embodiments, the side wall of the water tank housing 7100 includes a first recess 7110 extending upward along the bottom of the water tank housing to exceed the highest water level line 7111, and a second recess 7120 extending upward along the bottom of the water tank housing to exceed a preset height, the height of the second recess 7120 is not limited. Here, the first recess 7110 is bounded by fitting together with at least a portion of the boss 2600, the top surface of the first recess 7110 forms at least a portion of the bottom surface of the water tank projection 7140, the top surface of the first recess 7110 includes a clean water inlet, a sewage inlet, or a pit 7221, etc., and is connected to an air pump port 2610, a sewage tank connection port 2620, a clean water tank connection port 2630, or a soft rubber projection 2640 provided on the boss 2600, and the second recess 7120 is bounded by fitting together with a projection on the inner side wall of the water storage chamber 2700. The recesses provided in the water tank housing 7100 achieve overall restriction of the water storage tank 7000, allowing the water storage tank 7000 to be positioned relatively accurately in the corresponding location in the water storage chamber 2700 and avoiding misalignment of the water storage tank 7000.

[0083] The top cover 7200 covers the top of the water tank housing 7100, is detachably connected to the water tank housing 7100, and is openable and closable relative to the water tank housing 7100. When the top cover 7200 is closed, the liquid inside the water tank housing 7100 is isolated from the outside, preventing foreign objects from falling into the water storage tank 7000. Optionally, when the top cover 7200 is closed, the top cover 7200 makes airtight contact with the water tank housing 7100, and together they form a sealed structure.

[0084] A clean water outlet, a sewage outlet, or a pit 7221 is provided on the lower surface of the water tank projection 7140. If the water storage tank 7000 is a sewage tank 5000, a sewage outlet is provided on the lower surface of the water tank projection 7140. If the water storage tank 7000 is a clean water tank 4000, a clean water outlet is provided on the lower surface of the water tank projection 7140. When the water storage tank 7000 is assembled in the water storage chamber 2700, the water tank projection 7140 is supported by the boss 2600 in the water storage chamber 2700, and the sewage outlet or clean water outlet provided on the lower surface of the water tank projection 7140 is connected to the projection opening at the top of the boss 2600.

[0085] In some embodiments, the water storage tank 7000 is a wastewater tank 5000, and an air pump connector is further provided on the lower surface of the water tank projection 7140, which is connected to an 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, wastewater can be drawn from the wastewater tank 5000. In some embodiments, the air pump draws air from inside the wastewater tank 5000 through the air pump connection port 2610 and the air pump connector, and because the wastewater tank 5000 is a sealed structure, a negative pressure is formed inside during the air extraction process, and wastewater in the cleaning groove is drawn into the wastewater tank 5000 through the wastewater pipe and the wastewater tank connection port 2620.

[0086] A plurality of pits 7221 are further provided on the underside of the water tank projection 7140. When the water storage tank 7000 is assembled in the water storage chamber 2700, the water tank projection 7140 is supported by the boss 2600 in the water storage chamber 2700, and the plurality of pits 7221 provided on the underside of the water tank projection 7140 cooperate with the soft rubber protrusions on the top of the boss 2600 to achieve the limiting of the water storage tank 7000. The cooperation and limiting of the soft rubber protrusions 2640 and the pits 7221 makes the position of the water storage tank 7000 in the water storage chamber 2700 more precise and prevents misalignment of the water storage tank 7000.

[0087] As shown in Figure 5, in some embodiments, the water storage tank 7000 is a clean water tank 4000, in which case the water storage tank 7000 further includes a water pipe bracket 7300 and a water pipe 7400. The water pipe bracket 7300 is provided on a projection structure 7900 inside the clean water tank 4000, the projection structure 7900 is formed corresponding to a first recess 7110, and the projection structure 7900 is higher than the highest water level line of the clean water tank 4000. The water pipe 7400 extends from the water pipe bracket 7300 to the bottom of the clean water tank 4000, and liquid flows to the outside of the clean water tank 4000 through the water pipe 7400. The water pipe 7400 has a water pipe inlet and a water pipe outlet, where the water pipe inlet is located at the bottom of the clean water tank 4000 and the water pipe outlet is located on the water pipe bracket 7300 and the water pipe outlet is connected to the clean water inlet of the clean water tank 4000.

[0088] In some embodiments, the water storage tank 7000 is a clean water tank 4000, in which case the water storage 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, which is connected to the float ball base 7500 and can rotate around a fixed axis of the float ball base 7500 and is configured to detect the water level in the tank.

[0089] In some embodiments, the water storage tank 7000 is a clean water tank 4000, in which case the water storage tank 7000 may further include a filter 7700. The filter 7700 is located at the end of the water pipe inlet and is configured to filter the liquid as it enters the water pipe 7400.

[0090] The water storage tank 7000 may further include a handle 7800. The handle 7800 may be hinged to the top of the water storage tank 7000. Providing the handle 7800 makes it easier to attach and detach the water storage tank 7000 and facilitates the user's routine replacement of the liquid inside the water storage tank 7000.

[0091] The embodiments of this disclosure provide a self-cleaning dust collection sheet, in which at least a portion of the water tank is exposed to the outside of the self-cleaning dust collection sheet body for convenient attachment and detachment by the user, and by providing the water inlet of the water tank at the top of the water tank, the liquid in the water tank is less likely to overflow, and damage to electronic components due to overflowing liquid can be avoided.

[0092] In related technologies, a self-cleaning dust collection sheet fan is installed in a fan bin, the fan bin is located at the bottom of the dust collection bin, and a ventilation hole is formed at the bottom of the dust collection bin. When the fan is working, the suction force generated draws air out of the dust collection bin, which is then discharged to the outside of the self-cleaning dust collection sheet body 2000 through an air duct in the fan bin. Because the distance between the dust collection port and the cleaning groove is relatively short, residual water in the cleaning groove may be brought into the dust collection port when the robot climbs onto or leaves the pile. If there is too much water, it may be sucked into the dust collection bin through the air duct when the fan is working, and if too much water accumulates in the dust collection bin, there is a risk of fan damage or electric shock.

[0093] Therefore, the embodiments of this disclosure provide a self-cleaning dust collection sheet, and by providing a drain hole at the bottom of the dust collection bottle, liquid that enters the dust collection bottle can be immediately discharged. Similar structures have similar technical effects, some of which are omitted from this explanation. Specifically, as shown in Figure 6, the self-cleaning dust collection sheet includes a self-cleaning dust collection sheet bottom plate 1000 and a self-cleaning dust collection sheet body 2000, the bottom plate 1000 being detachably or non-detachably connected to the self-cleaning dust collection sheet body 2000 for convenient transport. The self-cleaning dust collection sheet body 2000 includes a dust collection chamber 2100, and a dust collection cover 2800 covers the dust collection chamber 2100 to form a dust collection bin 3000. The dust collection chamber 2100 is integrally provided at the top end of the self-cleaning dust collection sheet body 2000, and the dust collection chamber 2100 is recessed inward at the top end of the self-cleaning dust collection sheet body 2000 to form a dust collection chamber 2100 for housing various components for dust collection. The dust collection chamber 2100 has drainage holes 2101, which are provided at the bottom of the dust collection chamber. There may be one or more drainage holes 2101, and this can be set according to the internal space of the dust collection chamber 2100, and is usually located at the bottom of the dust collection chamber. The self-cleaning dust collection sheet body 2000 is positioned for convenient liquid discharge and further includes an air duct 2500, one end of which communicates with a dust collection port 6100 of the main 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, the air inlet 2102 communicates with the dust collection port 6100 of the main body base 6000 via the air duct 2500, and the air duct is formed in the side wall of the self-cleaning dust collection sheet body 2000 and extends downward, passing through the main body base 6000 and communicating with the dust collection port 6100 on the main body base 6000.Here, when the self-cleaning dust collection sheet is in a dust collection state, the internal airflow of the dust collection bin 3000 communicates with the outside of the dust collection bin 3000 via the air duct 2500, the drain hole 2101 does not communicate with the outside of the dust collection bin 3000, ensuring that sufficient negative pressure is formed inside the dust collection bin, and the dust in the dust box is sucked into the dust collection bag through the dust collection port and air duct, and when the self-cleaning dust collection sheet is not in a dust collection state, the dust collection bin The air intake port inside the 3000 is closed, preventing the internal airflow of the dust collection bin 3000 from communicating with the outside of the dust collection bin 3000, while the drain hole 2101 communicates with the outside of the dust collection bin 3000. In this case, even if liquid, such as water on a mop cloth, enters the dust collection bin 3000 through the air duct during the dust collection process, the drain hole 2101 opens, allowing the liquid to flow out of the dust collection bin 3000 and preventing damage to components inside the dust collection bin, especially the fan.

[0094] 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 2101 due to the negative pressure inside the bin, preventing the drain hole 2101 from communicating with the outside of the dust collection bin 3000. When the self-cleaning dust collection sheet is not in a dust collection state, the drain valve 2103 opens under the influence of gravity, allowing the drain hole 2101 to communicate with the outside of the dust collection bin 3000.

[0095] In some embodiments, the drain valve 2103 includes a fixed end 21031 and an elastically movable end 21032, the fixed end 21031 being fixedly attached to the outside of the bottom of the dust collection bin 3000 by screws, adhesive, clamps, etc., and the elastically movable end 21032 being positioned at the outlet of the drain hole 2101 so as to be switchable between an open and closed state. The elastically movable end 21032 is made of a soft rubber stopper material such as rubber or plastic, and 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 is automatically discharged from the drain hole 2101. When the fan is running, negative pressure is created inside the dust collection bin 3000, and the elastically movable end 21032 is automatically attracted to the outside of the drain hole to achieve sealing. After the fan stops, the elastically movable end 21032 is automatically opened by gravity, and if there is water in the dust collection bin 3000, it is again discharged from the drain hole 2101.

[0096] In some embodiments, the side wall of the dust collection bin 3000 includes a water baffle structure 2104, which is provided on the edge of the air inlet 2102 and configured to block liquid from 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 to block liquid from entering through the air inlet 2102.

[0097] In some embodiments, the self-cleaning dust collection sheet body 2000 further includes a fan bin 2200, a fan passage 2210, and a fan 2220, wherein the fan bin 2200 is located below the dust collection bin 3000 and is used to house the fan; the fan passage 2210 is configured to connect the fan bin and the dust collection bin and to provide suction airflow into the dust collection bin by the fan; and the fan 2220 is located within the fan bin and is openable and closable under the control of a control system and is used to provide the suction airflow necessary for dust collection. In some embodiments, the fan passage 2210 extends upward by a predetermined distance along the bottom of the dust collection bin 3000, so that the fan passage 2210 protrudes from the bottom of the dust collection bin 3000, thereby preventing liquid entering the dust collection bin 3000 from entering the fan bin 2200 and causing fan damage if the liquid is not immediately discharged.

[0098] The self-cleaning dust collection sheet body provided by this embodiment includes a dust collection bin, the dust collection bin includes a drain hole provided at the bottom of the dust collection bin and an air duct having one end communicating with the bottom plate and the other end communicating with the dust collection bin. When the self-cleaning dust collection sheet is in a dust collection state, the air duct communicates with the outside of the dust collection bin, and the drain hole does not communicate with the outside of the dust collection bin, ensuring a negative pressure state inside the dust collection bin, which is convenient for dust collection operations. When the self-cleaning dust collection sheet is not in a dust collection state, the drain hole communicates with the outside of the dust collection bin, allowing water that has entered the dust collection bin to be immediately discharged, thus preventing damage to parts inside the dust collection bin.

[0099] In related technologies, the fan inside a self-cleaning dust collection sheet vibrates significantly during the dust collection process due to its own rotation, damaging the wall of the fan bin in contact with it, and also generating considerable noise due to the vibration.

[0100] Therefore, this embodiment provides a self-cleaning dust collection sheet, and by providing multiple vibration damping devices in the fan bin, vibrations caused by the rotation of the fan are reduced, and similar structures have similar technical effects, some of which are omitted from this explanation. Specifically, as shown in Figure 7, the self-cleaning dust collection sheet includes a self-cleaning dust collection sheet bottom plate 1000 and a self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet bottom plate 1000 is detachably or non-detachably connected to the self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet body 2000 includes a fan bin 2200, a fan 2220 and a vibration damping device 2230, and the fan bin 2200 is connected to the self-cleaning dust collection sheet body 20 Integrated inside the 00, the fan bin 2200 includes an air inlet 2240 and an air outlet 2250, the air inlet 2240 communicating with the dust collection bin 3000 through a fan passage 2210, and is used to draw in air by the rotation of the fan, to draw out gas from inside the dust collection bin 3000, and to ensure negative pressure inside the dust collection bin 3000, after which the drawn-out gas enters the fan through the air inlet 2240 and is discharged from the air outlet 2250. The fan 2220 is installed inside the fan bin 2200 and rotates in forward or reverse direction under the control of the control system. A vibration damper 2230 is provided on at least a portion of the outer surface of the fan 2220 and is used to reduce vibration of the fan 2220, and the vibration damper 2230 may be made of an elastic material such as rubber or plastic.

[0101] In some embodiments, specifically as shown in Figure 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 the vibration of the fan, the shape of the vibration damping cover 2231 which conforms to the fan top end structure, and the vibration damping cover 2231 which is provided just to cover the fan top end. Specifically, in some embodiments, the vibration damping cover 2231 has a vibration damping cover top surface 22311 which includes a first opening 22312 which conforms to the air inlet 2240, a sealing vibration damping member which extends outward along the first opening 22312, and specifically includes a protruding edge 22313 which is assembled between the top end of the fan 2220 and the air inlet 2240 and configured to reduce the vibration of the fan. In some embodiments, the opening area of ​​the protruding edge 22313 gradually increases as the distance it extends outward increases, so that, after the vibration damping cover 2231 is assembled to the fan top surface and then to the fan bin, the trumpet-shaped protruding edge 22313, i.e., the top-surface sealing vibration damping member 22313, is supported just around the fan bin air inlet, sealing the air inlet while simultaneously reducing the effects of vibration and noise. In some embodiments, the vibration damping cover top surface 22311 may further include at least one projection that extends continuously around the circumferential direction of the first opening 22312, and is configured to abut against the inner wall of the top surface of the fan bin 2200 to reduce vibrations of the fan 2220. In some embodiments, the vibration damping cover top surface 22311 may further include a first projection 22314, a second projection 22315, and a third projection 22316 extending continuously around the circumferential direction of the first opening 22312, with a groove 22317 extending continuously around the circumferential direction of the first opening 22312 between the second projection 22315 and the third projection 22316, so that the first projection 22314, the second projection 22315, the third projection 22316, and the groove 22317 are pressed and deformed during the assembly process, reducing the rigid connection between the fan and the fan bin and further reducing vibration damage. In some embodiments, the interior of the third projection 22316 has multiple discontinuous cavities, further reducing the vibration of the fan.

[0102] In some embodiments, as shown in Figure 8, the vibration damping cover includes a vibration damping cover side wall 22318 which extends downward along the vibration damping cover top surface 22311, and when the vibration damping cover 2231 is provided to cover the fan top surface, the vibration damping cover side wall 22318 wraps around the fan side, where the vibration damping cover side wall 22318 includes a plurality of spaced first protruding beams 22319, the first protruding beams 22319 are hollow in structure, and the outer wall of each first protruding beam 22319 abuts against the side wall of the fan bin 2200 to further reduce vibration during fan operation.

[0103] In some embodiments, as shown in Figure 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 vibrations of the fan 2200. In some embodiments, as shown in Figure 10, the vibration damping pad 2232 includes a second opening 22322 that fits the bottom end of the fan 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 in structure, and the side walls 2231 of the second protruding beams contact the bottom of the fan 2200 to further reduce the vibration of the fan. After the vibration damping pad 2232 is assembled to the bottom end of the fan 2200, the fan bottom end air outlet structure enters the second opening 22322, and the fan bottom end is interference-fitted with the assembly projection 22324 of the vibration damping pad 2232, and the fan bottom end plane contacts the plurality of second protruding beams 22321 that extend laterally along the upper surface of the vibration damping pad 2232, with the hollow second protruding beams 22321 playing a vibration-reducing role. In some embodiments, the vibration damping pad 2232 further includes a plurality of third protruding beams 22323 extending longitudinally along the inner wall of the second opening 22322, and the fan bottom end air outlet structure enters the second opening 22322 and then comes into close contact with the plurality of third protruding beams 22323, the third protruding beams 22323 being hollow structures, further reducing the vibration of the fan.

[0104] According to the self-cleaning dust collection sheet provided in this embodiment, the self-cleaning dust collection sheet body includes a fan provided 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, so that the effect of the fan's vibration on the self-cleaning dust collection sheet can be reduced.

[0105] In related technologies, the cleaning module at the bottom of an automatic cleaning device (e.g., the mop cloth bracket of a wet cleaning module) is usually a lifting structure and does not adhere tightly to the bottom of the automatic cleaning device under natural gravity. Also, if the dust collection port of the automatic cleaning device is at the front of the cleaning groove, the cleaning module at the bottom of the automatic cleaning device will pass through the dust collection port when climbing onto or away from 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, making it difficult for the automatic cleaning device to climb onto or away from the pile. In particular, when the automatic cleaning device climbs onto the pile, the driving force required to climb onto the pile in the opposite direction is usually not large, so it cannot climb onto the pile smoothly. Furthermore, if the cleaning module is a wet cleaning module, the mop cloth that has just been cleaned is not completely dry, so when it rubs against the dust collection port, the water on the mop cloth is squeezed into the dust collection port and sucked into the dust collection box, leading to damage to the fan.

[0106] Therefore, the embodiments of this disclosure provide a self-cleaning dust collection sheet, and by providing a lifting structure on the bottom plate body, the cleaning module can be prevented from being rubbed or becoming immobile during the process of the automatic cleaning device climbing onto or away from the pile, and the success rate of the automatic cleaning device climbing onto or away from the pile can be increased. Similar structures have similar technical effects, some of which are not described here.

[0107] Specifically, the self-cleaning dust collection sheet provided by the embodiments of this disclosure is illustrated in Figures 11 and 12, which illustrate the self-cleaning dust collection sheet bottom plate connected to the main body base from different angles, and Figure 13, which is a schematic diagram illustrating the structure of the self-cleaning dust collection sheet bottom plate.

[0108] As shown in Figure 1, the self-cleaning dust collection sheet provided by this embodiment includes a self-cleaning dust collection sheet base plate 1000 and a self-cleaning dust collection sheet body 2000.

[0109] The self-cleaning dust collection sheet body 2000 is configured to collect dust from the dust box of an automatic cleaning device. In some embodiments, components such as a dust collection bin 3000, a clean water tank 4000, and a wastewater tank 5000 may be further provided on the self-cleaning dust collection sheet body 2000. A main body base 6000 is integrally provided below the self-cleaning dust collection sheet body 2000. In some embodiments, the self-cleaning dust collection sheet bottom plate 1000 is detachably or non-detachably connected to the main body base 6000 for convenient transport.

[0110] In some embodiments, the body base 6000 below the self-cleaning dust collection sheet body 2000 includes a cleaning groove 6200, which is configured to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device and / or to contain debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0111] As shown in Figure 11, the self-cleaning dust collection sheet bottom plate 1000 includes a bottom plate body 1100 and a lifting structure 1300.

[0112] The base plate body 1100 is configured to support the automatic cleaning device when it returns to the self-cleaning dust collection sheet base plate 1000. That is, the automatic cleaning device can move onto the self-cleaning dust collection sheet base plate 1000 and be supported by the base plate body 1100. Specifically, in the process of the automatic cleaning device moving onto the self-cleaning dust collection sheet base plate 1000, the drive wheels of the automatic cleaning device travel on the inclined surface of the base plate body 1100.

[0113] Referring together to Figures 11 and 12, the main body base 6000 and the bottom plate body 1100 are sequentially provided along a first direction X, and the bottom plate 1000 is interconnected with 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 bottom plate body 1100 also has a start end and a stop end, with the stop end of the main body base 6000 in contact with the start end of the bottom plate body 1100. In some embodiments, the main body base 6000 is connected to the bottom plate body 1100 in a detachable or non-detachable manner for convenience of transport.

[0114] The main body base 6000 and the bottom plate body 1100 form a continuous inclined surface along at least a first direction X, allowing the drive wheels of the automatic cleaning device to travel over it relatively smoothly. In some embodiments, the drive wheels of the automatic cleaning device are located on both sides of the bottom, and accordingly, the main body base 6000 and the bottom plate body 1100 form a continuous inclined surface adapted to the position of the drive wheels, over which the drive wheels travel. In some embodiments, the bottom plate body 1100 further includes a recess 1121 and a projection 1122, where the recess 1121 is located in the center of the bottom plate body 1100 and the projection 1122 is located on both sides of the recess. The angle between the upper surface and the horizontal surface of the recess 1121 is smaller than the angle between the upper surface and the horizontal surface of the projection 1122.

[0115] In some embodiments, the angle between the upper surface and the horizontal surface of the recess 1121 may be close to zero. The starting end of the projection 1122 abuts against the stopping end of the main body base 6000 and is at the same height, and the projection 1122 and the main body base 6000 form two continuous inclined surfaces that fit the drive wheels. By providing the recess 1121 at the central position of the bottom plate body 1100, it is possible to prevent the automatic cleaning device from being obstructed or rubbed by the surface of the bottom plate body 1100 during the process of climbing onto and away from the pile.

[0116] Furthermore, the projection 1122 of the base plate body 1100 is provided with an anti-slip structure 1123 along the first direction X, and this anti-slip structure 1123 is provided at least at the starting end and stopping 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 projection extending along the second direction Y, where the second direction Y is perpendicular to the first direction X. Providing the anti-slip structure 1123 on the projection 1122 can further help the automatic cleaning device to smoothly climb onto and off the pile.

[0117] In some embodiments, the main body base 6000 has a top surface called the first top surface, and when the main body base 6000 is placed on a horizontal ground, the top surface of the main body base 6000 has a predetermined inclination angle with respect to the horizontal plane, and the inclination coefficient corresponding to this predetermined inclination angle is called the first inclination coefficient. Similarly, the bottom plate body 1100 has a top surface called the second top surface, and when the bottom plate body 1100 is placed on a horizontal ground, the top surface of the bottom plate body 1100 has a predetermined inclination angle with respect to the horizontal plane, and the inclination coefficient corresponding to this predetermined inclination angle is called the second inclination coefficient. In some embodiments, the bottom plate body 1100 includes a recess 1121 and a projection 1122, and the second inclination coefficient is the inclination coefficient of the top surface of the projection 1122 with respect to the horizontal plane. In some embodiments, the first inclination coefficient and the second inclination coefficient have a relationship in which the first inclination coefficient is greater than the second inclination coefficient. The power required by the automatic cleaning device immediately after climbing onto the pile is relatively small, and setting the second inclination coefficient small is beneficial for the automatic cleaning device to climb onto the pile.

[0118] As shown in Figure 13, the dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and debris in the dust box of the automatic cleaning device enters the dust collection station of the self-cleaning dust collection sheet 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 to the dust outlet of the automatic cleaning device, and is used to prevent debris leakage. The dust collection port 6100 is located on the upper surface of the main body base 6000 and is provided approximately at the edge of the connection between the main body base 6000 and the bottom plate body 1100.

[0119] Referring together to Figures 11 and 12, the lifting structure 1300 is provided on the upper surface of the base plate body 1100 and is located approximately at the edge of the connection between the base plate body 1100 and the main body base 6000. In some embodiments, the lifting structure 1300 is provided in a recess 1121 of the base plate body 1100. The lifting structure 1300 is configured to press the cleaning module on the bottom surface of the automatic cleaning device during the process in which the automatic cleaning device moves toward the self-cleaning dust collection sheet base plate 1000 in the reverse direction (at which time the front side of the main body faces the first direction X, which is the outside of the self-cleaning dust collection sheet body 2000), causing the cleaning module to move toward the inside of the automatic cleaning device, for example, so that the cleaning module on the bottom surface of the automatic cleaning device is pushed into the automatic cleaning device.

[0120] During the process in which the automatic cleaning device moves in the opposite direction along the first direction X to the self-cleaning dust collection sheet bottom plate 1000 and brings the dust outlet of the automatic cleaning device into contact with the dust collection port 6100 of the main body base 6000, if a 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 (for example, the mop cloth bracket of the wet cleaning module) may get caught on the dust collection port 6100 as it passes through it, and the automatic cleaning device 100 may not be able to smoothly climb onto or detach from the pile.

[0121] A lifting structure 1300 is provided on the upper surface of the base plate body 1100. In the process of the automatic cleaning device moving in the reverse direction along the first direction X to the self-cleaning dust collection sheet base plate 1000 and bringing the cleaning module of the automatic cleaning device into contact with the cleaning groove in the self-cleaning dust collection sheet body 2000, first the lifting structure 1300 is brought into contact with at least a portion of the frame of the cleaning module, lifting the cleaning module to a certain height (e.g., 8 mm). At this time, the cleaning module is pressed by the lifting structure 1300 and moves toward the inside of the automatic cleaning device (e.g., pushed into the automatic cleaning device by the lifting structure 1300). Subsequently, as the automatic cleaning device continues to move in the reverse direction along the first direction X, the frame of the cleaning module passes above the dust collection port 6100 and gradually detaches from the lifting structure 1300. Even if the cleaning module completely detaches from the lifting structure 1300 during this process, part or all of the cleaning module remains above the dust collection port 6100, and the cleaning module can pass through the dust collection port 6100 in close contact with it. After the cleaning module has completely passed through the dust collection port 6100, under the influence of gravity, it is gradually restored to its state before being pressed by the lifting structure 1300, that is, at least a portion of the cleaning module protrudes toward the automatic cleaning device. In this way, the cleaning module descends by a certain height (e.g., 8 mm) under the influence of gravity, and the cleaning module comes into contact with the cleaning groove.

[0122] By providing a lifting structure 1300 on the upper surface of the base plate body 1100, the dust collection port 6100 is prevented from obstructing the cleaning module during the process of the automatic cleaning device climbing onto and away from the pile, thereby improving the success rate of the automatic cleaning device climbing onto and away from the pile.

[0123] In some embodiments, the lifting structure 1300 includes a wedge-shaped member 1310 and a roller 1320.

[0124] The wedge-shaped member 1310 is provided on the upper surface of the base plate body 1100 and protrudes from the upper surface of the base 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 in sequence along the first direction X, and the first inclined surface 1311, the first top surface 1313, and the second inclined surface 1312 are in sequential contact in the first direction X.

[0125] The acute angle between the first inclined surface 1311 and the upper surface of the base plate body 1100 is defined as the first angle α, and the acute angle between the second inclined surface 1312 and the upper surface of the base plate body 1100 is defined as the second angle β. In some embodiments, the first angle α is smaller than the second angle β, and when the automatic cleaning device moves in the opposite direction along the first direction X onto the base plate body 1100, the automatic cleaning device is gently pressed and can descend quickly. Specifically, in some embodiments, the range of the first angle α may be 5° to 25°, for example 10° to 15°, and when the automatic cleaning device moves in the opposite direction along the first direction X onto the base plate body 1100, the cleaning module on the bottom surface of the automatic cleaning device is smoothly pressed by the lifting structure 1300. In some embodiments, the range of the second angle β may be 75° to 90°, for example 80° to 85°, and after the frame of the cleaning module is released from the lifting structure 1300, it descends quickly under the action of gravity.

[0126] When the wedge-shaped member 1310 is provided in the recess 1121 of the base plate 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 projection 1122 of the base plate body 1100, the first angle α is the angle between the first inclined surface 1311 and the upper surface of the projection 1122, and the second angle β is the angle between the second inclined surface 1312 and the upper surface of the projection 1122.

[0127] The roller 1320 is provided on the first top surface 1313 and rollably contacts the cleaning module during the process of moving the cleaning module toward the interior of the automatic cleaning device when pressing the cleaning module on the bottom surface of the automatic cleaning device. By providing the roller 1320, frictional resistance between the frame of the cleaning module and the wedge-shaped member 1310 can be reduced, wear between components can be reduced, and the service life of each component can be extended.

[0128] In some embodiments, a portion of the roller 1320 is embedded within the wedge-shaped member 1310, allowing the sliding contact between the lifting structure 1300 and the frame of the cleaning module to smoothly transition to rolling contact. In some embodiments, to facilitate the replacement of the roller 1320, the roller 1320 is detachably connected to the wedge-shaped member 1310.

[0129] In some embodiments, there are at least two lifting structures 1300, which are positioned opposite each other in a second direction Y, and the second direction Y is perpendicular to the first direction X. As the automatic cleaning device moves in opposite directions along the first direction X onto the base plate body 1100, the at least two lifting structures 1300 each come into contact with the frame of the cleaning module, and the cleaning module is lifted uniformly by a certain height. By providing two or more lifting structures 1300, the force applied to the cleaning module is better distributed, and displacement of the cleaning module in the second direction Y due to uneven force distribution can be avoided.

[0130] In some embodiments, there are two lifting structures 1300, which are positioned opposite each other in a second direction Y, and are substantially symmetrical with respect to the central axis of the base plate body 1100. The distance between the two lifting structures 1300 is equivalent to or slightly greater than the width of the dust collection port 6100 in a second direction Y, so as not to obstruct the main brush cover below the automatic cleaning device.

[0131] In some embodiments, the self-cleaning dust collection sheet bottom plate 1000 further includes an inclined body 1400, which may be a slope, and is provided on the surface of the bottom plate body 1100. Specifically, the inclined body 1400 may be provided at the edge of the connection between the bottom plate body 1100 and the main body base 6000, and is provided approximately in front of the dust collection port 6100 and along the central axis of the bottom plate body 1100. In some embodiments, there are two lifting structures 1300, which are provided opposite each other in a second direction Y, and the inclined body 1400 is provided substantially in the center of the two lifting structures 1300. By providing the inclined body 1400 on the surface of the bottom plate body 1100, it is possible to prevent the front end of the automatic cleaning device (particularly the collision sensor provided at the front end) from coming into contact with the edge of the dust collection port 6100 when the automatic cleaning device is climbing the pile.

[0132] In some embodiments, the inclined surface 1400 is provided in a recess 1121 of the base plate body 1100. In some embodiments, as shown in Figure 13, both the inclined surface 1400 and the lifting structure 1300 are provided in a recess 1121 of the base plate body 1100. By providing a recess 1121 at the central position of the base plate body 1100 and providing the inclined surface 1400 and the lifting structure 1300 in the recess 1121, it is possible to avoid the automatic cleaning device being obstructed by or rubbed against the surface of the base plate body 1100 during the process of climbing up to and away from the pile.

[0133] In some embodiments, the lifting structure 1300 is provided in a recess 1121 of the base plate body 1100, and the height of the lifting structure 1300 is greater than the projection 1122, effectively pressing the cleaning module on the bottom surface of the automatic cleaning device, thereby allowing the cleaning module to move a large distance towards the inside of the automatic cleaning device.

[0134] In some embodiments, the inclined surface 1400 is provided in a recess 1121 of the base plate body 1100, and the height of the inclined surface 1400 is substantially flush with the projection 1122. If the height of the inclined surface 1400 is too low, it will not be able to prevent the automatic cleaning device from touching the edge of the dust collection port 6100 when climbing onto the pile, and if the height of the inclined surface 1400 is too high, it will obstruct the automatic cleaning device during the process of climbing onto and away from the pile.

[0135] In some embodiments, the lifting structure 1300 is at a predetermined distance from the stopping end of the base plate body 1100, and this predetermined distance prevents the automatic cleaning device from moving backward onto the self-cleaning dust collection sheet base plate 1000. In such cases, the lifting structure 1300 does not come into contact with the cleaning module before the drive wheels of the automatic cleaning device reach the stopping end of the base plate body 1100. This is because the backward force of the automatic cleaning device is relatively small before the drive wheels of the automatic cleaning device come into contact with the anti-slip structure 1123 at the starting end. If the lifting structure 1300 were to come into contact with the cleaning module (such as a mop cloth bracket) at this time, it could hinder the automatic cleaning device from climbing the pile, potentially leading to failure to climb the pile. In response to this, when the drive wheels of the automatic cleaning device enter the stopping end of the base plate body 1100, the lifting structure 1300 may come into contact with the cleaning module, at which point the automatic cleaning device has already stepped on the anti-slip structure 1123, and with the help of the anti-slip structure 1123, the automatic cleaning device can smoothly climb onto and off the pile.

[0136] This disclosure further provides an automatic cleaning device and a dust collection system comprising a self-cleaning dust collection sheet of the above embodiment.

[0137] The self-cleaning dust collection sheet and dust collection system provided by the embodiments of this disclosure can avoid the phenomenon of the cleaning module being rubbed or becoming immobile during the process of the automatic cleaning device climbing onto or away from the pile by providing a lifting structure on the bottom plate body, thereby improving the success rate of the automatic cleaning device climbing onto or away from the pile.

[0138] In related technologies, the air duct structure of self-cleaning dust collection sheets is usually complex, occupying more physical space and making the self-cleaning dust collection sheet appear bulky. Furthermore, the complex air duct structure also reduces the dust collection efficiency to some extent, making it difficult to suck all the dust in the dust box into the dust collection chamber of the self-cleaning dust collection sheet.

[0139] Therefore, the embodiments of this disclosure provide a self-cleaning dust collection sheet, optimize the air duct structure inside the self-cleaning dust collection sheet, and shorten the air duct path, thereby making the air duct of the self-cleaning dust collection sheet smoother and more compact in structure, and further improving the dust collection efficiency of the automatic cleaning device.

[0140] Specifically, regarding the self-cleaning dust collection sheet provided by the embodiments of this disclosure, as an example, Figure 14 is a schematic diagram illustrating the overall structure of a dust box combined with the self-cleaning dust collection sheet, and Figures 15 and 16 are diagrams specifically showing the air duct structure of the self-cleaning dust collection sheet and the direction of airflow in the air duct when dust is collected.

[0141] As shown in Figure 14, the self-cleaning dust collection sheet provided by this embodiment includes a self-cleaning dust collection sheet base plate 1000 and a self-cleaning dust collection sheet body 2000. Here, the self-cleaning dust collection sheet base plate 1000 is detachably or non-detachably connected to the self-cleaning dust collection sheet body 2000, specifically, the self-cleaning dust collection sheet base plate 1000 is detachably or non-detachably connected to the body base 6000 at the bottom of the self-cleaning dust collection sheet body 2000. A detachable connection method facilitates transportation and maintenance.

[0142] The self-cleaning dust collection sheet body 2000 is configured to collect debris in the dust box of an automatic cleaning device. In some embodiments, components such as a dust collection bin 3000, a clean water tank 4000, and a wastewater tank 5000 are provided side by side within the self-cleaning dust collection sheet body 2000. Specifically, as shown in Figure 2, the self-cleaning dust collection sheet body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 is located at the top of the self-cleaning dust collection sheet body 2000 and opens upward and forward, and the water storage chamber further includes a clean water bin for housing the clean water tank 4000 and a wastewater bin for housing the wastewater tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000, alongside the water storage chamber 2700. The dust collection chamber 2100 constitutes a dust collection bin 3000 for housing the dust collection cover 2800. The upward and forward orientation of the water storage chamber 2700 and the dust collection chamber 2100 facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800.

[0143] A main body base 6000 is located below the self-cleaning dust collection sheet main body 2000. In some embodiments, the main body base 6000 is integrally provided below the self-cleaning dust collection sheet main body 2000. The main body base 6000 is further in contact with the self-cleaning dust collection sheet bottom plate 1000, specifically, the self-cleaning dust collection sheet bottom plate 1000 and the main body base 6000 are provided sequentially along a second direction, which is opposite to the direction of the arrow on the front-rear axis X.

[0144] As shown in Figure 14, the dust collection port 6100 is provided on the main body base 6000 and is located approximately at the edge of the connection point with the self-cleaning dust collection sheet bottom plate 1000 on the main body base 6000. The dust collection port 6100 is configured to abut with the dust outlet of the automatic cleaning device, so that debris in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collection sheet main body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, which is used to seal the abutted dust collection port 6100 and the dust outlet of the automatic cleaning device and prevent debris leakage. The dust collection port 6100 extends substantially along a first direction, which is opposite to the direction of the arrow of the transverse axis Y, and which is substantially perpendicular to a second direction. The first direction is also the longitudinal direction of the dust collection port 6100, and the extension distance of the dust collection port 6100 in the first direction can be denoted as length L1. The dust collection port 6100 extends along the first direction and simultaneously extends along the second direction, which is the width direction of the dust collection port 6100, and the extension distance of the dust collection port 6100 in the second direction can be denoted as width W1, and furthermore, there is a relationship between length L1 and width W1 such that L1 > W1.

[0145] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean cleaning members on the automatic cleaning device, for example, to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device and / or to contain debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100. The cleaning groove 6200 extends along a second direction to the lower part of the self-cleaning dust collection sheet body 2000, and a side wall may be formed between the self-cleaning dust collection sheet body 2000 and the cleaning groove 6200.

[0146] Referring together to Figures 15 and 16, the self-cleaning dust collection sheet 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 collection sheet is in the dust collection state, sufficient negative pressure is formed inside the dust collection bin 3000, and the dust in the dust box 300 is sucked into the dust collection bag through the dust collection port 6100 and the air duct 2500. Depending on its location, the air duct 2500 is further divided into a main body air duct 2510 and a base air duct 2520. The base air duct 2520 is substantially located in the position indicated by the dashed box in the lower right corner of Figure 15, and the main body air duct 2510 is substantially located in the position indicated by the dashed box in the upper right corner of Figure 15. In Figures 15 and 16, the solid arrows indicate the movement trajectories of dust driven by airflow in the base air duct 2520 and the main air duct 2510.

[0147] Specifically, the base air duct 2520 is located inside the main body base 6000, and the base air duct 2520 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 collection sheet main body 2000. Specifically, the base air duct 2520 communicates with the longitudinal direction of the dust collection port 6100 and extends along the first direction to approximately the edge of the main body base 6000, and then extends along the 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 debris it drives directly out of the longitudinal end of the dust collection port 6100 and then advances along a nearly straight line, reducing resistance as the airflow flows out of the dust collection port 6100. In some embodiments, the base air duct 2520 extends along a second direction between the edge of the cleaning groove 6200 and the edge of the main body base 6000, making full use of the limited space of the main body base 6000 and reducing the overall size of the product. In some embodiments, the width of the base air duct 2520 is 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 air duct's cross-section. For example, if the cross-section of the air duct is circular or nearly circular, the width of the air duct will be the diameter of the circle or the length of the major axis of the ellipse. By appropriately reducing the width of the base air duct 2520, the airflow velocity 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, thus preventing clogging of the base air duct 2520 and improving the dust collection effect. In some embodiments, the base air duct 2520 is formed by a smooth, arc-shaped connection between the curved sections extending in the first direction and the curved sections extending in the second direction, and the first and second directions are nearly perpendicular. However, the bends in the first and second directions of the base air duct 2520 are not right angles, but are replaced by arc sections tangent to two sides of the corner, making the airflow through the base air duct 2520 gentler and preventing abrupt changes in flow velocity.Similarly, the curved section of the base air duct 2520 extending along the second direction and the curved section extending above the main air duct 2510 are formed as a smooth, arc-shaped connection.

[0148] The main air duct 2510 is provided at least on the side wall of the self-cleaning dust collection sheet body 2000, one end of the main air duct 2510 is in communication with the base air duct 2520, and the other end is in communication with the dust collection chamber 2100, so that the main air duct 2510 connects the base air duct 2520 and the dust collection chamber 2100. Specifically, the main air duct 2510 extends upward along the side wall of the self-cleaning dust collection sheet body 2000 to the dust collection 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 collection sheet body 2000. With the above design of the main air duct 2510, the space between the self-cleaning dust collection sheet body 2000 and the cleaning groove 6200 can be fully utilized, making the structure more compact. In some embodiments, the width of the main air duct 2510 is greater than the width of the base air duct 2520. By appropriately adjusting the width relationship between the main air duct 2510 and the base air duct 2520, the airflow velocity 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, thus preventing clogging of the base air duct 2520 and improving the dust collection effect.

[0149] In some embodiments, the main air duct 2510 and the base air duct 2520 are two separate structures connected by a connector, and the separate structure facilitates pipeline maintenance, especially when the pipeline becomes clogged. In some embodiments, the main air duct 2510 and the base air duct 2520 are an integrated structure, and the integrated structure effectively prevents airflow leakage in the air duct.

[0150] This disclosure further provides a self-cleaning dust collection sheet, which includes a dust collection chamber 2100 provided at the top of the self-cleaning dust collection sheet, a main air duct provided at least in part on the side wall of the self-cleaning dust collection sheet, a cleaning groove 6200 provided at the bottom of the self-cleaning dust collection sheet and configured to clean cleaning members on an automatic cleaning device, a dust collection port 6100 configured to collect dust after abutting with the dust outlet of the automatic cleaning device, and a base air duct communicating with the dust collection port 6100 and configured to extend along the outer edge direction of the cleaning groove 6200 until communicating with the main air duct, wherein the dust collection port 6100 communicates with the dust collection chamber 2100 via the base air duct and the main air duct. This layout of air ducts makes effective use of the space at the bottom of the self-cleaning dust collection sheet and provides a simple path and high dust collection efficiency because it is a direct dust collection path from the dust collection port to the dust collection chamber.

[0151] This disclosure further provides an automatic cleaning device and a dust collection system comprising a self-cleaning dust collection sheet as in the above embodiment.

[0152] Referring together to Figures 14 and 16, the figures show a dust box 300 included in the automatic cleaning device, which has a dust inlet 310 and an air inlet 320, where the air inlet 320 is located on the side wall of the dust box 300 in the first extending direction toward the base air duct 2520, and the dust inlet 310 is located on the side wall of the dust box 300 toward the self-cleaning dust collection sheet body 2000, and the dust inlet 310 is abutted against the dust outlet of the automatic cleaning device.

[0153] Under dust collection conditions, the air inlet 320 of the dust box 300 opens, the first fan on the self-cleaning dust collection sheet starts working, and draws out gas from the dust collection chamber 2100 and air duct 2500. The air pressure inside the dust collection chamber 2100 and air duct 2500 decreases, forming a U-shaped passage through which air flows 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 the debris inside the dust box 300, and the debris inside the dust box 300 is lifted by the airflow and finally drawn into the dust collection chamber 2100. The U-shaped passage is the optimal inflow and outflow passage for airflow. The design of the U-shaped passage allows the airflow to flow more smoothly, making it easier to remove debris from the dust box and enter the dust collection bin through the air duct.

[0154] According to the self-cleaning dust collection sheet and dust collection system provided by the embodiments of this disclosure, by optimizing the air duct structure inside the self-cleaning dust collection sheet, the air duct path can be shortened, the airflow of the air duct in the self-cleaning dust collection sheet can be improved, the structure can be made more compact, the dust collection efficiency of the automatic cleaning device can be further improved, and the complexity of the air duct design and the length of the path can be reduced and the dust collection efficiency can be further improved by providing the air duct along the outer edge of the cleaning groove, while making full use of the limited space of the self-cleaning dust collection sheet.

[0155] In related technologies, the dustbins of automatic cleaning devices have limited capacity, often requiring users to bend down to clean them, resulting in a poor user experience. Therefore, embodiments of this disclosure provide a self-cleaning dust collection sheet, which uses a dust collection system to concentrate the debris in the dustbin of the automatic cleaning device and collect it in the dust collection bin of the self-cleaning dust collection sheet, thereby reducing the number of times users have to dispose of the debris and improving the user experience. Specifically, as an example of the self-cleaning dust collection sheet provided by embodiments of this disclosure, Figure 14 is a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet, and Figure 17 is a schematic diagram illustrating the structure of the self-cleaning dust collection sheet body after the wastewater tank, clean water tank, and dust collection cover of this disclosure have been removed.

[0156] As shown in Figure 14, the self-cleaning dust collection sheet bottom plate 1000 protrudes forward from the self-cleaning dust collection sheet body 2000, the rear wall direction of the self-cleaning dust collection sheet body 2000 is to the rear, the dust collection bin 3000 is to the left of the self-cleaning dust collection sheet, the clean water tank 4000 is to the right of the dust collection bin 3000, and the wastewater tank 5000 is to the right of the clean water tank 4000.

[0157] The self-cleaning dust collection sheet body 2000 is configured to collect debris in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collection sheet body 2000 is further provided with components such as a dust collection bin 3000, a clean water tank 4000, and a wastewater tank 5000.

[0158] As shown in Figure 17, the self-cleaning dust collection 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 located at the top of the self-cleaning dust collection sheet body 2000. The water storage chamber may further include a water bottle for housing a clean water tank 4000 and a wastewater bottle for housing a wastewater tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000, alongside the water storage chamber 2700. A dust collection cover 2800 is provided on the dust collection chamber 2100 to fit the opening of the dust collection chamber 2100. The dust collection cover 2800 is detachably fitted onto the dust collection chamber 2100, and together with the dust collection cover 2800, the dust collection chamber 2100 forms a dust collection bottle 3000 for housing a waste collection device. At least a portion of the outer surface of the dust collection cover 2800 functions as part of the outer surface of the self-cleaning dust collection sheet. The water storage chamber 2700 and the dust collection chamber 2100 are designed to face upward and forward, which facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800.

[0159] A main body base 6000 is located below the self-cleaning dust collection sheet main body 2000. In some embodiments, the main body base 6000 is integrally provided below the self-cleaning dust collection sheet main body 2000. The main body base 6000 is further in contact with the self-cleaning dust collection sheet bottom plate 1000, specifically, the self-cleaning dust collection sheet bottom plate 1000 and the main body base 6000 are provided sequentially along a second direction, which is opposite to the direction of the arrow on the front-rear axis X.

[0160] The dust collection port 6100 is provided on the main body base 6000, and is located approximately at the edge of the connection point between the main body base 6000 and the self-cleaning dust collection sheet bottom plate 1000. The dust collection port 6100 is configured to align with the dust outlet of the automatic cleaning device, and debris in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collection sheet main body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, and the sealing rubber gasket is used to seal the abutted dust collection port 6100 and the dust outlet of the automatic cleaning device, preventing debris leakage.

[0161] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean cleaning members 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 debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0162] In some embodiments, the self-cleaning dust collection sheet further includes an air duct, one end of which communicates with a dust collection port 6100 of the main body base 6000, and the other end of which communicates with a dust collection chamber 2100. When the self-cleaning dust collection sheet is in the dust collection state, sufficient negative pressure is formed in the dust collection bin 3000, and the dust in the dust box 300 is sucked into the dust bag in the dust collection chamber 2100 via the dust collection port 6100 and the air duct.

[0163] Referring together to Figures 17 and 18, in some embodiments, the dust collection chamber 2100 includes a rear dust collection chamber wall 2134 and a pair of opposing dust collection chamber side walls, the dust collection chamber side walls further including a first dust collection chamber side wall 2131 and a second dust collection chamber side wall 2132, the first dust collection chamber side wall 2131 is adjacent to the outer wall of the self-cleaning dust collection sheet body 2000 and the first dust collection chamber side wall 2131 is provided opposite the second dust collection chamber side wall 2132, both of which are adjacent to the rear dust collection chamber wall 2134.

[0164] Specifically, the end face of the dust collection chamber side wall may have an arc-shaped structure, the height of the dust collection chamber side wall tends to gradually decrease along the direction of the arrow on the front-rear axis X, and at the adjacent part between the dust collection chamber side wall and the dust collection chamber rear wall 2134, the height of the dust collection chamber side wall is equal to the height of the dust collection chamber rear wall 2134. The dust collection chamber side wall adopts an arc-shaped structure that is lower at the front and higher at the rear, which facilitates the attachment and detachment of the dust collection cover 2800 and improves the aesthetic appearance to some extent.

[0165] In some embodiments, the first dust collection chamber side wall 2131, the second dust collection chamber side wall 2132, and the dust collection chamber rear wall 2134 are integrally structured with the self-cleaning dust collection sheet body 2000, thereby improving the stability of the dust collection chamber 2100 and preventing the dust collection chamber 2100 from shaking relative to the self-cleaning dust collection sheet body 2000.

[0166] In some embodiments, the dust collection chamber 2100 further includes a circumferential inner wall 2150, which extends from the bottom wall of the dust collection chamber 2100 toward the cleaning dust collection sheet body 2000. The rear wall 2134 and side walls of the dust collection chamber are provided around the circumferential inner wall 2150, spaced apart from it. The heights of all parts of the circumferential inner wall 2150 may differ, and in some embodiments, the height of the circumferential inner wall 2150 tends to gradually decrease along the direction of the arrow on the front-rear axis X, and such a structural design of the circumferential inner wall 2150, with the front side being lower and the rear side higher, facilitates the attachment and detachment of the dust collection cover 2800.

[0167] In some embodiments, the circumferential inner wall 2150 may have a closed-loop structure and include a sequentially connected front inner wall 2153, a first side inner wall 2151, a rear inner wall 2154, and a second side inner wall 2152, where the front inner wall 2153 is provided opposite the rear inner wall 2154, and the first side inner wall 2151 is provided opposite the second side inner wall 2152. Furthermore, each inner wall of the circumferential inner wall 2150 corresponds to the rear wall 2134 of the dust collection chamber and the side walls of the dust collection chamber. Specifically, the first side inner wall 2151 and the first dust collection chamber side wall 2131 are on the same side and spaced apart, the rear inner wall 2154 and the rear wall 2134 of the dust collection chamber are on the same side and spaced apart, and the second side inner wall 2152 and the second dust collection chamber side wall 2132 are on the same side and spaced apart.

[0168] In some embodiments, the circumferential inner wall 2150 and the bottom wall of the self-collecting dust chamber 2100 are integrally structured, which improves the stability of the circumferential inner wall 2150.

[0169] In some embodiments, the dust collection chamber 2100 may further include a sealing pad 2140, which is provided around the circumferential inner wall 2150, and the rear wall 2134 and side walls of the dust collection chamber are provided around the sealing pad 2140. In some embodiments, the sealing pad 2140 has a closed-loop structure, and the width of all parts of the sealing pad 2140 may be equal to or slightly greater than the distance between the circumferential inner wall 2150 and the rear wall 2134 and side walls of the dust collection chamber, so that the sealing pad 2140 is in close contact with the circumferential inner wall 2150, the rear wall 2134 and side walls of the dust collection chamber. The material of the sealing pad 2140 may be various natural or synthetic rubbers. The sealing pad 2140 allows the dust collection chamber 2100 and the dust collection cover 2800 fitted over the dust collection chamber 2100 to be tightly and closely fitted together, forming a sealed dust collection bin 3000.

[0170] In some embodiments, a dust bag bracket 2110 is further provided within the dust collection chamber 2100, and the dust bag bracket 2110 is configured to attach a dust bag. The dust bag bracket 2110 is provided inside the dust collection chamber 2100 and extends from the bottom of the dust collection chamber toward the self-cleaning dust collection sheet body 2000. The dust bag bracket 2110 may be provided on the circumferential inner wall 2150 of the dust collection chamber 2100 by fastening members such as screws, or it may be fixed to the bottom wall of the dust collection chamber via the bottom of the dust bag bracket 2110. In some embodiments, the dust bag bracket 2110 is provided on the first side inner wall 2151, and the side wall of the dust bag bracket 2110 toward the dust collection chamber 2100 may be integrally formed with the first side inner wall 2151, which can improve the stability of the dust bag bracket 2110. The dust bag bracket 2110 has a hollow cavity inside which functions as part of the air duct of the self-cleaning dust collection sheet, for example, as the tail end of the air duct. The dust bag bracket 2110 has a bracket side wall facing the inside of the dust collection bin 3000, and a dust outlet is provided in the bracket side wall. The dust outlet communicates with the dust collection port 6100 via an air duct, and the air duct is configured to guide the debris into the dust collection bin 3000, for example, into the dust bag inside the dust collection bin 3000. The dust outlet is configured to communicate with the inlet of the dust bag in order to collect the debris into the dust bag.

[0171] Referring together to Figures 19 and 20, in some embodiments the dust collection cover 2800 includes a dust collection cover body 2810 and a dust collection cover wall 2820, where the dust collection cover body 2810 is located above the dust collection cover wall 2820, and the dust collection cover wall 2820 extends in a direction away from the dust collection cover body 2810. The dust collection cover body 2810 together with the dust collection cover wall 2820 forms a containment space, and in response to the dust collection cover 2800 aligning with the dust collection chamber 2100, the circumferential inner wall 2150 is housed within the containment space, and the free end of the dust collection cover wall 2820 away from the dust collection cover body 2810 is in close contact with the sealing pad 2140 to form a sealed dust collection bin 3000.

[0172] In some embodiments, the dust collection cover wall 2820 further includes a sequentially connected dust collection cover front wall 2823, a first side wall 2821 of the dust collection cover, a dust collection cover rear wall 2824, and a dust collection cover second side wall 2822. Here, the dust collection cover front wall 2823 is provided opposite the dust collection cover rear wall 2824, and the dust collection cover first side wall 2821 is provided opposite the dust collection cover second side wall 2822.

[0173] As the dust collection cover 2800 aligns with the dust collection chamber 2100, at least a portion of the first side wall 2821 of the dust collection cover is sandwiched between the first dust collection chamber side wall 2131 and the first side inner wall 2151, at least a portion of the second side wall 2822 of the dust collection cover is sandwiched between the second dust collection chamber side wall 2132 and the second side inner wall 2152, and the rear wall 2824 of the dust collection cover is sandwiched between the rear wall 2134 and the rear inner wall 2154 of the dust collection chamber.

[0174] In some embodiments, the dust collection cover 2800 further includes a handle portion 2811, which is provided on the side of the dust collection cover body 2810 away from the dust collection cover wall 2820. The handle portion 2811 may be a structure such as a pull ring, pull rod, or handle provided on the dust collection cover body 2810, and by providing the handle portion 2811, the dust collection cover 2800 can be attached and detached more easily, which is convenient for the user to routinely remove dust from the dust collection bin 3000.

[0175] In some embodiments, the dust collection cover 2800 may further include a limiting member 2825, which is provided on the dust collection cover wall 2820 and may be positioned with a limiting portion provided in the dust collection chamber 2100 so that the dust collection cover 2800 is firmly engaged on the dust collection chamber 2100 without shaking. The limiting portion may be provided on at least one of the rear wall 2134 of the dust collection chamber and the side wall of the dust collection chamber. The limiting member 2825 is provided in a one-to-one correspondence with the limiting portion and cooperates with it. In the embodiment shown in Figure 19, the limiting member 2825 is provided on the second side wall 2822 of the dust collection cover, and the limiting portion corresponding to the limiting member 2825 is provided on the second dust collection chamber side wall 2132. In response to the dust collection cover 2800 being aligned on the dust collection chamber 2100, the limiting member 2825 comes into contact with the limiting portion.

[0176] In some embodiments, support ribs 2173 are provided on at least one of the dust collection chamber bottom wall, the circumferential inner wall 2150, and the dust collection cover wall 2820. The support ribs 2173 may be a strip-shaped structure that protrudes outward from the surface. In the embodiment shown in Figure 19, the support ribs 2173 are provided on the inner surface of at least the second side wall 2822 of the dust collection cover, and a plurality of support ribs 2173 are provided on the inner surface of the second side wall 2822 of the dust collection cover. By providing support ribs 2173, it is possible to prevent the dust bag in the dust collection bin 3000 from sticking to the dust collection chamber bottom wall, the circumferential inner wall 2150, and / or the dust collection cover wall 2820, thereby avoiding adverse effects on airflow outflow from the dust bag due to sticking.

[0177] This disclosure further provides an automatic cleaning device and a dust collection system comprising a self-cleaning dust collection sheet as in the above embodiment.

[0178] The embodiments of this disclosure utilize a dust collection system to centrally collect dust from the dust box of an automatic cleaning device into a dust collection bin of a self-cleaning dust collection sheet, thereby reducing the frequency of waste disposal by the user and improving the user experience.

[0179] In related technologies, the dust box of an automatic cleaning device has a limited capacity, often requiring users to bend down to clean it, resulting in a poor user experience. Therefore, an embodiment of this disclosure provides a self-cleaning dust collection sheet, in which a dust collection system concentrates the debris in the automatic cleaning device's dust box and collects it in the dust collection bin of the self-cleaning dust collection sheet. By providing a dust bag bracket and a dust bag inside the dust collection bin, the debris in the dust box is transferred to the dust bag in the dust collection bin without leakage, reducing the number of times the user has to handle the debris and improving the user experience. The dust bag employs a cooperative design of an engaging plate and a sliding plate, so that when the dust bag is removed from the dust bag bracket, the sliding plate is in a closed position, preventing debris from remaining in the dust collection bin.

[0180] Specifically, regarding the self-cleaning dust collection sheet provided by the embodiments of this disclosure, as an example, Figure 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet, and Figure 2 is a schematic diagram illustrating the structure of the self-cleaning dust collection sheet body after the wastewater tank, clean water tank, and dust collection cover of this disclosure have been removed.

[0181] As shown in Figure 1, the self-cleaning dust collection sheet bottom plate 1000 protrudes forward from the self-cleaning dust collection sheet body 2000, the rear wall direction of the self-cleaning dust collection sheet body 2000 is to the rear, the dust collection bin 3000 is to the left of the self-cleaning dust collection sheet, the clean water tank 4000 is to the right of the dust collection bin 3000, and the wastewater tank 5000 is to the right of the clean water tank 4000.

[0182] The self-cleaning dust collection sheet body 2000 is configured to collect debris in the dust box of an automatic cleaning device. In some embodiments, the self-cleaning dust collection sheet body 2000 is further provided with components such as a dust collection bin 3000, a clean water tank 4000, and a wastewater tank 5000. Specifically, as shown in Figure 2, the self-cleaning dust collection sheet body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 is located at the top of the self-cleaning dust collection sheet body 2000 and opens upward and forward, and the water storage chamber further includes a clean water bin for housing the clean water tank 4000 and a wastewater bin for housing the wastewater tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000, alongside the water storage chamber 2700. The dust collection chamber 2100 is provided with a dust collection cover 2800 that fits the opening of the dust collection chamber 2100. The dust collection cover 2800 is detachably engaged with the dust collection chamber 2100, and together with the dust collection cover 2800, the dust collection chamber 2100 forms a dust collection bin 3000. The upward and forward design of the water storage chamber 2700 and the dust collection chamber 2100 facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800.

[0183] A main body base 6000 is located below the self-cleaning dust collection sheet main body 2000. In some embodiments, the main body base 6000 is integrally provided below the self-cleaning dust collection sheet main body 2000. The main body base 6000 is further in contact with the self-cleaning dust collection sheet bottom plate 1000, specifically, the self-cleaning dust collection sheet bottom plate 1000 and the main body base 6000 are provided sequentially along a second direction, which is opposite to the direction of the arrow on the front-rear axis X.

[0184] The dust collection port 6100 is provided on the main body base 6000, and is located approximately at the edge of the connection point between the main body base 6000 and the self-cleaning dust collection sheet bottom plate 1000. The dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and debris in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collection sheet main body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, and the sealing rubber gasket is used to seal the abutted dust collection port 6100 and the dust outlet of the automatic cleaning device to prevent debris leakage.

[0185] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean cleaning members 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 debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0186] In some embodiments, the self-cleaning dust collection sheet further includes an air duct, one end of which communicates with a dust collection port 6100 of the main body base 6000, and the other end of which communicates with a dust collection chamber 2100. When the self-cleaning dust collection sheet is in the dust collection state, sufficient negative pressure is formed inside the dust collection bin 3000, drawing the dust from the dust box 300 through the dust collection port 6100 and the air duct into the dust bag in the dust collection chamber 2100.

[0187] Figure 21 is a schematic diagram showing the structure of a dust bag bracket provided by some embodiments of the present disclosure, with the sliding baffle in a first position. Figure 22 is a schematic diagram showing the structure of a dust bag bracket provided by some embodiments of the present disclosure, with the sliding baffle in a second position.

[0188] As shown in Figures 21 and 22, in some embodiments, the self-cleaning dust collection sheet further includes a dust bag bracket 2110, which is configured to attach a dust bag. The dust bag bracket 2110 is provided inside the dust collection bin 3000 and may be attached to the inner wall of the dust collection bin 3000 by fastening members such as screws, or it may be fixed to the bottom surface of the dust collection bin 3000 by the bottom of the dust bag bracket 2110.

[0189] The dust bag bracket 2110 has a hollow cavity inside, which functions as part of the air duct of the self-cleaning dust collection sheet, for example, as the tail end of the air duct.

[0190] The dust bag bracket 2110 has a bracket side wall 2111 facing the inside of the dust collection bin 3000, and a dust outlet 2112 is provided on the bracket side wall 2111. The dust outlet 2112 communicates with the dust collection port 6100 via an air duct, and the air duct is configured to guide the debris into the dust collection bin 3000, for example, into the dust bag inside the dust collection bin 3000. The dust outlet 2112 is configured to communicate with the entrance of the dust bag in order to collect the debris into the dust bag.

[0191] The dust bag bracket 2110 further includes a sliding baffle 2113 that is slidable on the bracket side wall 2111. The sliding baffle 2113 is configured to switch between a first position and a second position. In response to the sliding baffle 2113 being in the first position, the sliding baffle 2113 shields the dust outlet 2112, and in response to the sliding baffle 2113 being in the second position, the sliding baffle 2113 exposes the dust outlet 2112. Since the dust bag is a consumable item, it is detachably attached to the dust bag bracket 2110. By adopting the above design, the dust bag bracket 2110, when not attached to the dust bag, can block the dust outlet 2112 with the sliding baffle 2113, isolating the dust collection bin 3000 from the air duct. As a result, the suction force generated by the fan does not enter the air duct from the dust collection bin, thus preventing dust from entering the dust collection bin 3000 when the dust bag is not attached.

[0192] Figure 23 is a schematic diagram showing the structure of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in the closed position. Figure 24 is a schematic diagram showing the structure of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in the open position. Figure 24A is a schematic diagram showing a partial structure of a dust bag provided by some embodiments of the present disclosure, Figure 24B is a schematic diagram showing the cross-sectional structure in Figure 24A, Figure 24A shows a cross-section of the dust bag, and the dust bag is not shown in Figures 24 and 24B.

[0193] In some embodiments, as shown in Figure 23, the present disclosure further provides a dust bag 2120, which is detachably attached to a dust bag bracket 2110 and configured to collect waste.

[0194] The dust bag 2120 includes a dust bag body 2121, an engagement plate 2122, and a sliding plate 2123. The dust bag body 2121 is made from a material that is breathable but can filter fine particles, such as a nonwoven fabric or paper material, and is configured to contain the waste. The engagement plate 2122 is fixedly connected to the dust bag body 2121. The engagement plate 2122 has an engagement plate opening 21221, which functions as an entrance to the dust bag body 2121. The sliding plate 2123 is slidably connected to the engaging plate 2122 and is configured to switch between a closed position and an open position. In response to the sliding plate 2123 being in the closed position, the sliding plate 2123 shields the engaging plate opening 21221, and in response to the sliding plate 2123 being in the open position, the sliding plate 2123 exposes the engaging plate opening 21221.

[0195] Specifically, as shown in Figure 23, the sliding plate 2123 has a sliding plate opening 21231. In response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engaging plate 2122 does not overlap with the engaging plate opening 2821, and the sliding plate 2123 shields the engaging plate opening 22121, as shown in Figure 23. In response to the sliding plate 2123 being in the open position, the orthographic projection of the sliding plate opening 21231 onto the engaging plate 2122 overlaps at least partially with the engaging plate opening 21221, and the sliding plate 2123 exposes at least a portion of the engaging plate opening 21221 through the sliding plate opening 21231, as shown in Figure 24.

[0196] In some embodiments, the size of the sliding plate opening 21231 is larger than, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 covers the engagement plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is smaller than, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 lies within the engagement plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is equal to, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 substantially overlaps the engagement plate opening 21221.

[0197] The sliding cooperation between the sliding plate 2123 and the engaging plate 2122 closes the opening of the dust bag, preventing waste from leaking out of the dust bag.

[0198] In some embodiments, as shown in Figures 23 to 24B, a flexible rubber ring 21224 is provided on the edge of the engagement plate opening 21221, projecting toward the sliding plate 2123. In response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 passes through the sliding plate opening 21231 and projects toward the sliding plate 2123, sealing the gap created by the abutment of the two openings of the sliding plate 2123 and the engagement plate 21221 when the sliding plate opening 21231 and the engagement plate opening 21221 are brought into contact, thereby achieving a sealed connection between the sliding plate opening 21231 and the engagement plate opening 21221. In response to the sliding plate 2123 being in a position other than the open position, for example, the closed position, at least a portion of the flexible rubber ring 21224 is pressed between the sliding plate 2123 and the engaging plate 2122, increasing the frictional force between them. Unless a certain external force is applied, the sliding plate 2123 and the engaging plate 2122 cannot slide relative to each other, the sliding plate 2123 is stably held in the closed position, and the dispersion of dust in the dust bag can be prevented.

[0199] In some embodiments, as shown in Figures 23 and 24, the sliding plate 2123 is slidable relative to the engaging plate 2122 in a first direction M, and the sliding plate 2123 includes limiting projections 21243 provided on at least one side of the sliding plate 2123, for example on both sides of the sliding plate 2123, the limiting projections 21243 being, for example, two in number, and projecting from the sliding plate 2123 in a second direction perpendicular to the first direction M. The engaging plate 2122 includes limiting members 21223 provided at both ends of the engaging plate 2122 in the first direction, and configured to stop the limiting projections 21233 in the first direction M, thereby preventing the sliding plate 2123 from detaching from the engaging plate 2122. The limiting members 21223 being, for example, four in number, are distributed symmetrically on both sides of the engaging plate 2122. When the sliding plate 2123 slides against the engaging plate 2122, the limiting projection 21233 can only move between the corresponding limiting members 21223 at both ends of the engaging plate 2122 in the first direction.

[0200] In some embodiments, the sliding plate 2123 further includes a handle portion 21232 provided at one end of the sliding plate in a first direction M and configured to facilitate the operator's grip for moving the sliding plate 2123.

[0201] The dust bag 2120 is detachably mounted on the dust bag bracket 2110. In response to the dust bag 2120 being mounted on the dust bag bracket 2110, the sliding baffle 2123 is in a second position, exposing the dust outlet. In response to the sliding plate being in an open position, the engagement plate opening 21221 is connected to the dust outlet 2112. With this setup, when the dust bag bracket 2110 is not mounted on the dust bag 2120, the sliding baffle 2113 is in a first position, shielding the dust outlet 2112. This prevents the suction force generated by the fan from entering the air duct from the dust collection bin, thus preventing dust from entering the dust collection bin 3000 when the dust bag 2120 is not mounted.

[0202] When the dust bag 2120 is removed from the dust bag bracket 2110, the sliding plate is in the closed position 2123, preventing the dust in the dust bag from dispersing into the dust collection bin. Because it is a sealed dust bag, it is possible to prevent the dust in the dust bag from being dispersed into the external environment.

[0203] When the dust bag 2120 is not attached to the dust bag bracket 2110, the sliding plate 2123 shields the engagement plate opening 21221 of the engagement plate 2122. When the dust bag 2120 is attached to the dust bag bracket 2110, the sliding plate 2123 and the engagement plate 2122 work together to push the sliding baffle 2113 from the first position to the second position and fix it in that second position. When the dust bag 2120 is removed from the dust bag bracket 2110, the sliding plate 2123 shields the engagement plate opening 21221, preventing dust leakage. After the dust bag bracket 2110 is attached to the dust bag 2120, the engagement plate opening 21221 (i.e., the dust bag inlet) is connected to the dust outlet 2112, and under the action of the airflow provided by the fan, the debris in the dust box of the automatic cleaning device is sequentially collected into the dust bag body 2121 through the dust collection port 6100 on the main body base 6000, the air duct in the self-cleaning dust collection sheet, the dust outlet 2112 on the dust bag bracket 2110, and the engagement plate opening 21221 on the dust bag 2120.

[0204] Figure 25 is a schematic diagram of a pre-assembled dust bag bracket and dust bag provided by some embodiments of the present disclosure, and Figure 26 is a schematic diagram showing the assembled structure of the dust bag bracket and dust bag provided by some embodiments of the present disclosure.

[0205] In some embodiments, as shown in Figures 21 to 28, the dust bag bracket 2110 includes a sliding groove 2114, at least a portion of the sliding baffle 2113 is located within the sliding groove 2114, the sliding baffle 2113 is slidable along the extension direction X' of the sliding groove 2114, and is further switchable between a first position and a second position. The number of sliding grooves 2114 may be one or more, for example, as shown in Figures 21 to 28, for example, there may be two sliding grooves 2114, each provided at opposing ends of the bracket side wall 2111 of the dust bag bracket 2110, the two sliding grooves 2114 each accommodating the opposing ends of the sliding baffle 2113, and configured so that the sliding baffle 2113 can slide along the extension direction X' of the sliding groove 2114.

[0206] As shown in Figures 21 to 28, the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 are inserted into the sliding groove 2114 and slide along the extending direction X' of the sliding groove 2114, pushing the sliding baffle 2113 to slide along the extending direction X' of the sliding groove, thereby attaching the dust bag 2120 to the dust bag bracket 2110. Specifically, both ends of the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 can be inserted into the two sliding grooves 2114 described above. In response to the dust bag 2120 being attached to the dust bag bracket 2110, the sliding plate 2123 is in the open position, exposing the engagement plate opening 21221, the sliding baffle 2113 is in the second position, exposing the dust outlet 2112, and the engagement plate opening 21221 and the dust outlet 2112 are brought into contact.

[0207] As shown in Figure 25, during the process of attaching the dust bag 2120 to the dust bag bracket 2110, the dust bag 2120 moves relative to the dust bag bracket 2110 along the extending direction X' of the sliding groove 2114. When attaching the two, the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 face the bracket side wall 2111 of the dust bag bracket 2110, and in the process of inserting the engaging plate 2122 and sliding plate 2123 into the sliding groove 2114 along the extending direction X' of the sliding groove 2114, the sliding baffle 2113 is pushed to move from the first position to the second position.

[0208] In some embodiments, a sliding baffle projection 21131 is provided at the lower end of the sliding baffle 2113, and the sliding baffle projection 21131 is a band-shaped projection that runs along the lower edge of the sliding baffle 2113 toward the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding groove 2114, the lower end of the sliding plate 2123 comes into contact with the sliding baffle projection 21131. The lower ends of the sliding plate 2123 and the sliding baffle projection 21131, which are in contact with each other, push the sliding baffle 2113 and slide together along the extending direction X' of the sliding groove when the sliding plate 2123 slides downward along the extending direction X' of the sliding groove. In some embodiments, a sliding plate projection 21233 is also provided at the lower end of the sliding plate 2123, and this sliding plate projection 21233 is a band-shaped projection that runs along the lower edge of the sliding plate 2123 toward the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding groove 2114, the sliding plate projection 21233 abuts directly above the sliding baffle projection 21131. The mutually abutting sliding plate projection 21233 and the sliding baffle projection 21131 push the sliding baffle 2113 and slide together along the extending direction X' of the sliding groove when the sliding plate 2123 slides downward along the extending direction X' of the sliding groove.

[0209] Figure 26 shows a cross-sectional view of the dust bag bracket and dust bag assembly structure provided by some embodiments of the present disclosure, and Figure 27 is a schematic diagram showing the dust bag bracket and dust bag assembly structure provided by some embodiments of the present disclosure.

[0210] As shown in Figures 26 and 27, a buckle portion 21141, for example, an elastic snap fastener, is provided in the sliding groove 2114 and can move in a substantially arc shape as indicated by the arrow in Figure 27. The engaging plate 2122 includes an engaging plate engaging groove 21222 that fits the buckle portion 21141, and in response to the dust bag 2120 being attached to the dust bag bracket 2110, the buckle portion 21141 engages with the engaging plate engaging groove 21222. The engaging plate 2122 slides along the extending direction X' of the sliding groove 2114 to the engaging position, the engaging plate opening 21221 abuts against the dust outlet 2112, the buckle portion 21141 is clamped in accordance with the engaging plate engaging groove 21222, and the dust bag 2120 is fixed on the dust bag bracket 2110.

[0211] The restricting projection 212234 on the sliding plate 2123 also functions as a release projection 21234, also called the release projection 21234, and in the process of separating the sliding plate 2123 from the sliding groove 2114, it presses the buckle portion 21141, disengaging the buckle portion 21141 from the engagement plate engagement groove 21222, releasing the buckle portion 21141 from fixing the engagement plate 2122, and allowing the dust bag 2120 to be smoothly detached from the dust bag bracket 2110. In some embodiments, the release projection 21234 further has a restricting function and cooperates with a restricting member 21223 on the engagement plate 2122 to prevent the sliding plate 2123 from disengaging from the engagement plate 2122.

[0212] In some embodiments, as shown in Figure 28, an elastic member 2115, such as a spring, is provided in the dust bag bracket 2110. The elastic member 2115 is connected to the sliding baffle 2113 and configured to allow the sliding baffle 2113 to tend to be in a first position. When the sliding baffle 2113 is not subjected to external force, under the action of the elastic member 2115, the sliding baffle 2113 is in the first position and the sliding baffle 2113 blocks the dust outlet 2112. In some embodiments, the elastic member 2115 is located inside the dust bag bracket 2110, the extension direction of the elastic member 2115 substantially coincides with the extension direction of the sliding groove 2114, one end of the elastic member 2115 is fixed to the top of the dust bag bracket 2110 and the other end is connected to the sliding baffle 2113. The number of elastic members 2115 may be one or more. For example, if there are two elastic members 2115, each elastic member 2115 may be provided at opposite ends of the dust bag bracket 2110.

[0213] The following describes in detail the process of attaching and detaching the dust bag 2120 and the dust bag bracket 2110.

[0214] When the dust bag bracket 2110 is not attached to the dust bag 2120, the sliding baffle 2113 of the dust bag bracket 2110 is in the first position, blocking the dust outlet 2112, and the sliding plate 2123 on the dust bag 2120 is in the closed position, blocking the engagement plate opening 2122, i.e., the state shown in Figure 23. In the process of attaching the dust bag 2120 to the dust bag bracket 2110, the engaging plate 2122 and the sliding plate 2123 are inserted into the sliding groove 2114 along the extending direction X' of the sliding groove 2114. In the process of the user grasping the handle portion 21232 of the sliding plate 2123 and pushing the dust bag 2120 into the sliding groove 2114, the sliding plate 2123 gradually moves from a closed position to an open position relative to the engaging plate 2122, positioning the sliding plate opening 21231 on the sliding plate 2123 and the engaging plate opening 21221 on the engaging plate 2122. At the same time, the engaging plate 2122 and the sliding plate 2123 push the sliding baffle 2113, moving it from a first position to a second position, exposing the sliding baffle 2113 from the dust outlet 2112. When the engagement plate 2122 slides along the extension direction X' of the sliding groove 2114 to the engagement position, the engagement plate opening 21221 is connected to the dust outlet 2112, the buckle portion 21141 is clamped corresponding to the engagement plate engagement groove 21222, and the dust bag 2120 is fixed on the dust bag bracket 2110. At this time, the flexible rubber ring 21224 on the dust bag passes through the sliding plate opening 21231 and comes into contact with the edge of the dust outlet 2112, achieving sealing and abutting between the engagement plate opening 21221 of the dust bag and the dust outlet 2112 of the dust bag bracket, thereby preventing dust leakage during the dust collection process.

[0215] In the process of removing the dust bag 2120 from the dust bag bracket 2110, the operator can grasp the handle portion 21232 of the sliding plate 2123 and gradually separate the sliding plate 2123 from the sliding groove 2114 of the dust bag bracket 2110. In this process, the sliding plate 2123 moves from an open position to a closed position relative to the engaging plate 2122, the sliding plate 2123 blocks the engaging plate opening 21221, and the lock release projection 21234 on the sliding plate 2123 presses against the buckle portion 21141, thereby removing the buckle portion 21141. The engaging plate is disengaged from the engaging groove 21222, and simultaneously, the interaction between the unlocking projection 21234 and the limiting member 21223 on the engaging plate 2122 causes the handle portion 21232 of the sliding plate 2123 to be continuously pulled out, disengaging the sliding plate 2123 and the engaging plate 2122 from the sliding groove 2114 of the dust bag bracket 2110, disengaging the dust bag 2120 from the dust bag bracket 2110, and the sliding baffle 2113 returns to its first position under the action of the elastic member, causing the sliding baffle 2113 to block the dust outlet 2112.

[0216] In related technologies, the fan of a self-cleaning dust collection sheet is provided in a fan bin, which is provided adjacent to and in communication with the dust collection bin, for example, and the dust collection bin is in communication with the fan bin via a vent hole. When the fan in the fan bin operates, it generates suction force, drawing air out of the dust collection bin, creating negative pressure in the bin, which is then discharged to the outside of the pile through an air duct in the fan bin. When the self-cleaning dust collection sheet performs a dust collection operation, if the dust bag in the dust collection bin becomes full, the airflow through the dust collection path is lost, the negative pressure in the dust collection bin becomes excessive, and there is a risk of the fan being damaged.

[0217] Therefore, some embodiments of the present disclosure provide a self-cleaning dust collection sheet, in which a safety valve is provided in the dust collection bin, and when the negative pressure in the dust collection bin is greater than a safety threshold, the dust collection bin is connected to the outside atmosphere to prevent the negative pressure in the dust collection bin from becoming excessive.

[0218] Figure 29 is a schematic diagram showing the structure of a dust collection chamber provided by some embodiments of the present disclosure, as shown in Figure 29, some embodiments of the present disclosure provide a self-cleaning dust collection sheet, which includes a self-cleaning dust collection sheet bottom plate 1000 and a self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet body 2000 being detachably connected to the self-cleaning dust collection sheet bottom plate 1000. The self-cleaning dust collection sheet body 2000 includes a dust collection bin 3000, in which negative pressure is formed under the action of a fan, and dust is collected in the dust collection bin through a dust passage of the self-cleaning dust collection sheet into a dust collection device in the dust collection bin, such as a dust bag. A safety valve 2160 is provided in the dust collection bin 3000, which, in response to the negative pressure in the dust collection bin 3000 exceeding a safety threshold, connects the dust collection bin 3000 to the outside atmosphere to prevent the negative pressure in the dust collection bin from becoming excessive.

[0219] Figure 30 is a schematic diagram showing the structure of a safety valve provided by some embodiments of the present disclosure, Figure 31 is a schematic diagram showing the cross-sectional structure of a safety valve provided by some embodiments of the present disclosure, and Figure 31 shows the safety valve installed in a dust collection chamber.

[0220] As shown in Figures 30 and 31, the safety valve 2160 includes a safety valve base 2161 and a safety valve body 2162. A base through-hole 21611 is provided on the safety valve base 2161, and the safety valve body 2162, together with the safety valve base 2161, forms a safety valve cavity 2163. The base through-hole 21611 connects the dust collection bin 3000 and the safety valve cavity 2163. A safety valve air inlet 21621 is provided on the side of the safety valve body 2162 away from the safety valve base 2161, and the safety valve air inlet 21621 communicates with the outside atmosphere. The safety valve 2160 further includes a safety valve core 2164, which is movably provided within the safety valve cavity 2163 and configured to block the safety valve air inlet 21621 and isolate the safety valve cavity 2163 from the outside atmosphere.

[0221] Specifically, the safety valve core 2164 normally seals the safety valve air inlet 21621, isolating the safety valve cavity 2163 from the outside atmosphere, so that the dust collection bin 3000 is a substantially sealed space, and so that the dust collection bin 3000 is configured such that a negative pressure is formed under the action of the fan, and the dust is collected in the dust collection bin 3000 into a dust collection device, such as a dust bag, via the dust passage of the self-cleaning dust collection sheet.

[0222] When the self-cleaning dust collection sheet is performing its dust collection operation normally, the negative pressure in the dust collection bin is usually below a safety threshold. At this time, the safety valve core blocks the safety valve air inlet, and dust is collected in the dust collection device in the dust collection bin 3000, such as a dust bag, through the dust passage of the self-cleaning dust collection sheet. However, in the dust collection device, for example, when the dust bag is full of dust, or when the dust passage of the self-cleaning dust collection sheet is blocked, the continuous operation of the fan causes the negative pressure in the dust collection bin 3000 to become too low, and the desired dust collection effect cannot be obtained. When the negative pressure in the dust collection bin 3000 exceeds a safety threshold, the external atmospheric pressure is considerably higher than the pressure in the dust collection bin 3000 and the safety valve cavity 2163. Under the action of the pressure difference between the two, the safety valve core 2164 can move toward the safety valve base 2161, the safety valve air inlet 21621 opens, the safety valve cavity communicates with the outside through the safety valve air inlet 21621, and external air enters the dust collection bin 3000 sequentially through the safety valve air inlet 21621, the safety valve cavity 2163, and the base through-hole 21611, thereby balancing the excessively low negative pressure inside the dust collection bin 3000.

[0223] In some embodiments, as shown in Figures 30 and 10, the safety valve 2160 further includes an elastic member 2165, which is located within the safety valve cavity 2163 and is configured to allow the safety valve core 2164 to tend away from the safety valve base 2161. The elastic member 2165 holds the safety valve core 2164 in a position that blocks the safety valve air inlet 21621.

[0224] In some embodiments, the elastic member 2165 is a spring, with one end of the spring in contact with the safety valve base 2161 and the other end in contact with the safety valve core 2164.

[0225] In some embodiments, the safety valve base 2161 includes a safety valve base body 21612 and a projection 21613 extending from the safety valve base body 21612 toward the safety valve air inlet 21621. The base through-hole 21611 consists of a first sub-through-hole 21611a and a second sub-through-hole 21611b that penetrate the safety valve base body 21612 and the projection 21613 and communicate with each other. The first sub-through-hole 21611a and the second sub-through-hole 21611b are sequentially located near the safety valve air inlet 21621. The first sub-through-hole 21611a communicates with the dust collection bin 3000, and the second sub-through-hole 21611b communicates with the safety valve cavity 2163. The inner diameter of the first sub-through hole 21611a is smaller than the inner diameter of the second sub-through hole 21611b, and one end of the spring is provided in the second sub-through hole 21611b and abuts against the boundary between the first sub-through hole 21611a and the second sub-through hole 21611b. A stop hole 21641 is provided in the safety valve core 2164 on the side facing the safety valve base 2161, and the other end of the spring is provided in the stop hole 21641 and abuts against the bottom surface of the stop hole 21641. With this setup, both ends of the spring are housed in the second sub-through hole 21611b and the stop hole 21641, respectively, so that the force of the spring can be kept substantially in the horizontal direction in Figure 5, preventing the elastic member from deviating from this horizontal direction during expansion and contraction, and potentially making the safety valve 2160 lighter and thinner overall.

[0226] In some embodiments, as shown in Figures 30 and 31, the safety valve 2160 further includes a trigger switch 2166, which is located within the safety valve cavity 2163 and configured to generate a control signal when triggered, the control signal being configured to send an alarm and / or to stop the operation of the fan.

[0227] In some embodiments, when the safety valve core 2164 moves toward the safety valve base 2161 and the distance between the safety valve core 2164 and the safety valve base 2161 decreases to a predetermined value, the safety valve core 2164 contacts the trigger switch 2166 and triggers it.

[0228] The specific operating principle of the safety valve described herein is as follows: When the self-cleaning dust collection sheet performs a dust collection operation, its fan generates suction force, creating negative pressure in the dust collection bin 3000, and dust is collected through the dust passage of the self-cleaning dust collection sheet into a dust collection device in the dust collection bin 3000, such as a dust bag. If the dust passage of the self-cleaning dust collection sheet becomes blocked, or if the dust collection device in the dust collection bin 3000, such as a dust bag, becomes full of dust, the negative pressure in the dust collection bin 3000 may exceed a safety threshold under continuous fan operation. If the negative pressure inside the dust collection bin 3000 exceeds the safety threshold, the safety valve core 2164 in the safety valve 2160 moves toward the safety valve base 2161, overcoming the elastic force of the elastic member 2165 under the pressure difference between the external atmospheric pressure and the negative pressure inside the dust collection bin 3000. This opens the safety valve air inlet 21621, allowing the dust collection bin 3000 to communicate with the outside atmosphere through the safety valve cavity 2163, thus preventing excessive negative pressure inside the dust collection bin 3000.

[0229] When the distance traveled by the safety valve core 2164 in the safety valve 2160 to the safety valve base 2161 exceeds a predetermined distance, i.e., when the distance between the safety valve core 2164 and the safety valve base 2161 decreases to a predetermined value, the safety valve core 2164 triggers the trigger switch 2166. The trigger switch 2166 is, for example, a microswitch and is configured to transmit a control signal when triggered, which is controlled to, for example, stop the operation of the fan and protect the fan. The control signal is configured to emit an alarm, for example, by flashing an alarm lamp or emitting an alarm sound, prompting the user to check whether the dust bag is full or the dust passage of the self-cleaning dust collection sheet is blocked.

[0230] In some embodiments, as shown in Figure 29, the safety valve 2160 is provided on the inner wall of the dust collection bin 3000, for example, on the rear wall of the dust collection chamber 2100, while in other embodiments, the safety valve 2160 may be provided at another location, for example, on the bottom wall of the dust collection bin.

[0231] As shown in Figure 31, some embodiments of the present disclosure provide a self-cleaning dust collection sheet, which includes a self-cleaning dust collection sheet base plate 1000 and a self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet body 2000 being detachably connected to the self-cleaning dust collection sheet base plate 1000. The self-cleaning dust collection sheet body 2000 includes a dust collection bin 3000, which is configured such that a negative pressure is created under the action of a fan, causing dust to pass through the dust passage of the self-cleaning dust collection sheet and be collected in a dust collection device in the dust collection bin, such as a dust bag. A safety valve 2160 is provided in the dust collection bin 3000, and a trigger switch 2166 is provided on the safety valve 2160. The safety valve 2160, in response to the negative pressure in the dust collection bin exceeding a safety threshold, triggers a trigger switch 2166 in the safety valve cavity, which generates a control signal, the control signal being configured to issue an alarm and / or to stop the operation of the fan. Specifically, the control signal is configured to issue an alarm, for example, by emitting a sound or flashing light, or by sending information to a user's terminal, such as a mobile phone, to alert the user to an abnormal condition of the self-cleaning dust collection sheet, such as whether the dust bag is full or the dust passage of the self-cleaning dust collection sheet is blocked. The control signal is also configured to stop the operation of the fan to avoid damage due to overload operation of the fan.

[0232] In related technologies, the fan of a self-cleaning dust collection sheet is located in a fan bin, which is located at the bottom of the dust collection bin. A vent is provided at the bottom of the dust collection bin, and when the fan is operating, it generates suction force, drawing air out of the dust collection bin and discharging it to the outside of the self-cleaning dust collection sheet body 2000 through an air duct in the fan bin. Because the distance between the dust collection port and the cleaning groove is relatively short, residual water in the cleaning groove may be brought into the dust collection port when the robot climbs up or down the pile. If there is too much water, the water may be drawn into the dust collection bin through the air duct when the fan is operating, and if too much water accumulates in the dust collection bin, there is a risk of fan damage or electric shock.

[0233] Therefore, some embodiments of the present disclosure provide a self-cleaning dust collection sheet, comprising a self-cleaning dust collection sheet bottom plate and a self-cleaning dust collection sheet body, wherein the self-cleaning dust collection sheet bottom plate is detachably connected to the self-cleaning dust collection sheet body, the self-cleaning dust collection sheet body comprises a dust collection bin and a fan bin adjacent to each other, the dust collection bin and the fan bin are in communication via a fan passage, and a waterproof filter is provided around the fan passage and configured to allow gas to pass through but not water. This prevents water accumulated in the dust collection bin from entering the fan in the fan bin, thereby avoiding damage to the fan. Here, as a surrounding configuration, the objective of ensuring coordination between the filter and the fan passage can be achieved by embedding the waterproof filter directly at one end of the fan passage or inside the fan passage, or by aligning the waterproof filter with one end of the fan passage.

[0234] FIG. 32 is a schematic view showing a partial structural cross-section of a dust collection bin and a fan bin according to some embodiments of the present disclosure. As shown in FIG. 32, some embodiments of the present disclosure provide a self-cleaning dust collection sheet including a self-cleaning dust collection sheet bottom plate 1000 and a self-cleaning dust collection sheet body 2000. The self-cleaning dust collection sheet bottom plate 1000 is detachably connected to the self-cleaning dust collection sheet body 2000. The self-cleaning dust collection sheet body 2000 includes a dust collection bin 3000, a fan bin 2200, and a waterproof filter 2170 that are adjacent to each other. The dust collection bin 3000 and the fan bin 2200 communicate with each other through a fan passage 2210. The waterproof filter 2170 is provided around the fan passage 2210 and is configured to allow gas to pass through and prevent water from passing through. This prevents water accumulated in the dust collection bin 3000 from entering the fan 2220 in the fan bin 2200 and avoids damage to the fan 2220.

[0235] As shown in FIG. 32, the fan bin 2200 and the dust collection bin 3000 are sequentially provided away from the self-cleaning dust collection sheet bottom plate 1000, and the fan passage 2210 is provided, for example, on the bottom wall of the dust collection bin 3000.

[0236] In some embodiments, as shown in FIG. 32, an engagement groove 2171 is provided on the bottom wall of the dust collection bin 3000. The engagement groove 2171 is provided around the fan passage 2210, and the waterproof filter 2170 is provided in the engagement groove 2171. The engagement groove 2171 is used to fix the waterproof filter 2170. In some embodiments, the engagement groove 2171 is integrally formed with the bottom wall of the dust collection bin 3000.

[0237] In some embodiments, as shown in FIG. 32, the engagement groove 2171 includes a first groove wall 21711 and a second groove wall 21712. The first groove wall 21711 is provided around the fan passage 2210, the second groove wall 21712 is provided around the first groove wall 21711, and the waterproof filter 2170 is sandwiched between the first groove wall 21711 and the second groove wall 21712. Since the first groove wall 21711 and the second groove wall 21712 are provided around the fan passage 2210, they limit the position of the waterproof filter 2170.

[0238] In some embodiments, the first groove wall 21711 and the second groove wall 21712 extend from the bottom wall of the dust collection bin 3000 away from the fan bin 2200, and the height of the second groove wall 21712 is lower than the height of the waterproof filter 2170. This allows at least a portion of the outer wall of the waterproof filter 2170 to be exposed to the dust collection bin 3000, and when the fan 2220 is operating, airflow can enter the fan bin 2200 from the dust collection bin 3000 through the waterproof filter 2170 and the fan passage 2210.

[0239] Figure 33 is a schematic diagram showing a partial cross-sectional structure of a dust collection bin provided by some embodiments of the present disclosure, and as shown in Figures 32 and 33, in some embodiments the self-cleaning dust collection sheet further includes a cover body 2172 fitted to the end of the waterproof filter 2170 away from the fan bin 2200, and the orthographic projection of the cover body 2172 onto the bottom wall of the dust collection bin 3000 covers the fan passage 2210. Because the cover body 2172 covers the fan passage 2210, the airflow in the dust collection bin 3000 can only pass through the waterproof filter 2170 from the side and enter the fan bin 2200 through the fan passage 2210.

[0240] In some embodiments, as shown in Figures 32 and 33, the self-cleaning dust collection sheet further includes support ribs 2173 provided around the waterproof filter 2170 and configured to prevent the dust bag in the dust collection bin 3000 from enclosing the waterproof filter 2170 and causing poor ventilation.

[0241] In some embodiments, the support rib 2173 is provided on at least one of the top surface of the cover body 2172, the bottom wall of the dust collection bin 3000, or the side wall of the dust collection bin 3000.

[0242] Figure 34 is a schematic diagram showing the structure of a waterproof filter provided by some embodiments of the present disclosure, wherein the waterproof filter 2170 is ring-shaped.

[0243] As shown in Figures 32 to 34, even if some water accumulates at the bottom of the dust collection bin 3000, when the amount of water is small, the water level is lower than the height of the second groove wall 21712. In some embodiments, the second groove wall 21712, which is integrally formed with the bottom wall of the dust collection bin 3000, can prevent the water accumulated at the bottom of the dust collection bin 3000 from entering the fan passage 2210. Even if the water level is lower than the height of the second groove wall 21712, the installation of the waterproof filter 2170 prevents the water accumulated at the bottom of the dust collection bin 3000 from entering the fan 2220 in the fan bin 2200 through the fan passage 2210 and damaging the fan.

[0244] In related technologies, when a self-cleaning dust collection sheet performs its dust collection operation, the fan in the fan bin is in operation, and the airflow generated by the fan flows through the fan bin, producing relatively loud noise. To meet the noise requirements for household electronic devices and avoid causing discomfort to users, it is required that the noise from the self-cleaning dust collection sheet be reduced as much as possible when it performs its dust collection operation.

[0245] Therefore, some embodiments of the present disclosure provide a self-cleaning dust collection sheet, comprising a self-cleaning dust collection sheet bottom plate and a self-cleaning dust collection sheet body, wherein the self-cleaning dust collection sheet bottom plate is detachably connected to the self-cleaning dust collection sheet body, and the self-cleaning dust collection sheet body includes a dust collection chamber opening upward and forward and provided at the top end of the self-cleaning dust collection sheet body, a dust collection cover forming a dust collection bin that detachably accommodates a dust collection device on the dust collection chamber, a fan bin provided adjacent to the dust collection bin and configured to house a fan, and a sound-dampening structure provided inside the fan bin and configured to reduce noise generated during fan operation. By providing a sound-dampening structure inside the fan bin, noise caused by airflow during fan operation can be reduced.

[0246] Figure 35 is a schematic diagram showing the structure of a fan bin provided by some embodiments of the present disclosure. As shown in Figure 35, some embodiments of the present disclosure provide a self-cleaning dust collection sheet including a self-cleaning dust collection sheet base plate 1000 and a self-cleaning dust collection sheet body 2000, the self-cleaning dust collection sheet base plate 1000 being detachably connected to the self-cleaning dust collection sheet body 2000. The self-cleaning dust collection sheet body 2000 includes a dust collection chamber 2100, a dust collection cover 2800, a fan bin 2200 and a sound-dampening structure 2260. Specifically, the dust collection chamber 2100 is provided at the top end of the self-cleaning dust collection sheet body 2000, opening upward and forward, and the dust collection cover 2800 is configured to detachably fit over the dust collection chamber 2100 to form a dust collection bin 3000 for housing a waste collection device, such as a dust bag. The fan bin 2200 is provided adjacent to the dust collection bin 3000 and is configured to house the fan 2220. The fan bin 2200 is provided, for example, on the side of the dust collection bin 3000 closest to the self-cleaning dust collection sheet bottom plate 1000. The dust collection bin 3000 and the fan bin 2200 are connected through a fan passage 2210, which is provided, for example, on the bottom wall of the dust collection bin 3000. The sound-dampening structure 2260 is provided in the fan bin 2200, and the airflow generated by the fan 2220 flows through the sound-dampening structure 2260. The sound-dampening structure 2260 is configured to reduce the noise generated when the fan 2220 is operating.

[0247] In some embodiments, as shown in Figure 35, the fan bin 2200 includes a fan cover body 2270 and a fan bin air outlet 2280. The fan cover body 2270 is, for example, barrel-shaped and configured to house the fan 2220, and a cover body air outlet 2271 is opened in the side wall of the fan cover body 2270, which is, for example, a grid-like opening in the side wall of the fan cover body 2270. The fan bin air outlet 2280 is provided in the side wall of the fan bin 2200, allowing the fan bin 2200 to communicate with the outside atmosphere. The silencing device 2260 is provided between the cover body air outlet 2271 and the fan bin air outlet 2280. As the airflow generated by the fan 2220 flows out of the fan bin 2200 through the cover body air outlet 2271 and the fan bin air outlet 2280, the airflow flows through the silencing device 2260, thereby reducing noise caused by the airflow.

[0248] In some embodiments, Figure 36 is a schematic diagram showing the structure of a sound-absorbing structure provided by some embodiments of the present disclosure, as shown in Figures 35 and 36, the sound-absorbing structure 2260 includes a first sound-absorbing structure 2261 and a second sound-absorbing structure 2262, which are provided opposite to each other and spaced apart, and each of the first sound-absorbing structure 2261 and the second sound-absorbing structure 2262 extends from each of the cover body air outlets 2271 to the fan bin air outlets 2280, forming an air outlet path 2290 of the fan bin 2200. The specific structures of the first sound-absorbing structure 2261 and the second sound-absorbing structure 2262 are provided specifically according to the space within the fan bin, as shown in Figures 35 and 36, for example, the first sound-absorbing structure 2261 is flat and the second sound-absorbing structure 2262 is triangular prism-shaped, for example, the parallel surfaces of the first sound-absorbing structure 2261 and the second sound-absorbing structure 2262 sandwich each other to form the air outlet path 2290.

[0249] In the above embodiment, there are two sound-absorbing structures 2260, but in other embodiments, there may be multiple sound-absorbing structures, as long as they form an air outlet path. The air outlet path is not limited to the straight air passage shown in Figure 35, but may also be an arc-shaped air passage, a curved air passage, or the like.

[0250] In some embodiments, at least one of the first sound-absorbing structure 2261 and the second sound-absorbing structure 2262 includes a sound-absorbing shell 2263 and a sound-absorbing material 2264. The sound-absorbing shell 2263 is a bracket structure made of a material such as plastic or metal, and the sound-absorbing material 2264 is detachably housed within the sound-absorbing shell 2263 and may be, for example, sound-absorbing cotton. The sound-absorbing shell 2263 is provided with a plurality of sound-absorbing holes 22631 on the side facing the air outlet path 2290, and the airflow that has flowed through the air outlet path 2290 passes through the sound-absorbing holes 22631 and comes into contact with the sound-absorbing material 2264, thereby reducing noise during the flow process of the airflow.

[0251] In some embodiments, as shown in Figures 35 and 36, the plurality of sound-absorbing holes 22631 may be arranged in an array on the side of the sound-absorbing shell 2263 facing the air outlet path 2290.

[0252] In some embodiments, as shown in Figures 35 and 36, the plurality of sound-dampening holes 22631 may be circular, for example, and in other embodiments, the plurality of sound-dampening holes 22631 may be square, rectangular, elliptical, triangular, rhombus, or the like.

[0253] In some embodiments, the size and number of the sound-absorbing holes may be designed according to actual needs and relate to the noise frequency band of the airflow in the air outlet path 2290.

[0254] In some embodiments, the height of the sound-dampening structure 2260 is substantially equal to the internal height of the fan bin 2200.

[0255] In some embodiments, the sound-dampening structure 2260 is detachably provided within the fan bin 2200, making maintenance and replacement of the sound-dampening structure 2260 easier.

[0256] Some embodiments of the present disclosure further provide a dust collection system including an automatic cleaning device, such as a sweeper, a mopping sweeper, or a sweeping and mopping sweeper, and a self-cleaning dust collection sheet described in the embodiments.
