Abstract

Cleaning equipment comprises a chassis, a main machine body, a first bin, a second bin, a first suction device and a second suction device, the main machine body is rotationally connected with the chassis, the first bin is arranged on the main machine body, the second bin is communicated with the first bin, the first suction device is communicated with the first bin, and the first suction device provides power for driving external liquid to enter the first bin. The second suction device provides power for driving the liquid in the first bin into the second bin. Due to the existence of liquid driving force from the first bin to the second bin through the second suction device, the probability that liquid flows back into the first bin from the second bin under the condition that the cleaning equipment shakes or inclines or the main machine body lies down can be reduced, even the probability is zero, and the cleaning efficiency is improved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning equipment and a water tank thereof. BACKGROUND

[0002] With the continuous improvement of cleaning requirements and the continuous improvement of cleaning technology, various scrubbers have appeared in the field of cleaning and maintaining various hard surfaces such as floors, tiles and marbles. The working principle is generally that the front end of the cleaning assembly is rotated to clean the ground. While the roller brush body is rotating, clean water flows out from the roller brush body to wash and clean the dirt, oil stains and impurities on the ground. Then the dirty water is sucked back by the negative pressure device and stored in the cleaning equipment.

[0003] However, when the user uses or maintains the scrubber, the liquid in the cleaning equipment is easy to flow back or be sucked into the negative pressure device from the sewage tank or the clean water tank when the main body is tilted or shaken. On the one hand, the water entering the negative pressure device will affect the reliability of the cleaning equipment. On the other hand, the water entering the negative pressure device leaks through the gap of the cleaning equipment shell, causing secondary pollution to the cleaning equipment. The solution in the prior art is usually to limit the tilting angle of the main body of the cleaning equipment to reduce the risk of water entering the negative pressure device. However, this solution limits the use angle of the scrubber. Content of the utility model

[0117] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0118] It should also be understood that the terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and the appended claims of the present application, unless otherwise clearly indicated by the context, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0119] It should be further understood that the term "and / or" used in the specification and the appended claims of the present application means any combination of one or more of the associated listed items and all possible combinations thereof, and includes these combinations.

[0120] Some embodiments of the present application, the following embodiments and features in the embodiments can be combined with each other without conflict.

[0121] In some embodiments of the present application, referring to Figures 1-3 , the cleaning device 10 has a main body 100 and a chassis 200, the main body 100 is rotatably arranged on the chassis 200, the main body 100 has a handle 110 for a user to hold, and in the working process of the cleaning device 10, the user holds the handle 110 and pushes the chassis 200 by using the main body 100 to control the cleaning device 10 to advance, retreat or turn, so as to realize the cleaning of the surface to be cleaned by using the cleaning element 210 on the chassis 200. Generally, the cleaning device 10 has a clean water tank and a dirty water tank, the clean water tank supplies water for the cleaning element 210 or the ground, and the water can wet the surface to be cleaned, so that the cleaning element 210 can better clean the dirt on the ground. In the cleaning process, the cleaning device 10 recycles the generated dirt into the dirty water tank by using the first suction device 400 (such as a fan or other negative pressure source), and the first suction device 400 needs to be communicated with the dirty water tank. However, when the dirty water tank or part of the dirty water tank is located on the main body 100 of the cleaning device, in the working process of the cleaning device, due to the shaking, tilting (compared with the horizontal plane) or horizontal (compared with the horizontal plane) state of the main body 100, the water or water vapor in the dirty water tank is easy to enter the first suction device 400, thereby causing the first suction device 400 to be waterlogged, and even damaged, especially the smaller the angle of the main body 100 with the horizontal plane, the greater the probability of the first suction device 400 being waterlogged. Therefore, in order to ensure that the first suction device 400 will not be waterlogged, the angle at which the main body 100 can rotate relative to the chassis 200 is usually limited in the related technology. This solution makes the cleaning device 10 unable to clean low areas such as the bottom of the bed and the bottom of the sofa. Based on this, the present application provides the following solutions:

[0122] As shown in Figures 1-3 , the first aspect of the present application provides a cleaning device 10, which comprises a chassis 200, a main body 100, a first bin 310, a second bin 320, a first suction device 400 and a second suction device 500, wherein the main body 100 is rotatably connected with the chassis 200.

[0123] It should be noted that the main body 100 is rotatably connected with the chassis 200, so that the main body 100 can be switched between an upright state (such as Figure 1 ), a tilting state (such as Figure 2 ), a lying state (such as Figure 3 ) and the like. Among them, the length direction of the main body 100 (such as Figure 1When the direction of the dotted line is roughly perpendicular to the chassis 200 (or the horizontal plane), the cleaning device 10 is in an upright position, which is usually the placement posture of the cleaning device 10; when the length direction of the main body 100 is at an acute angle to the chassis 200 (or the horizontal plane), the cleaning device 10 is in an inclined position, which is usually the normal working posture of the cleaning device 10; and when the length direction of the main body 100 is roughly parallel to the chassis 200 (or the horizontal plane), the cleaning device 10 is in a lying position, which is usually the extreme working posture of the cleaning device 10, used for cleaning low areas, such as under beds and under sofas.

[0124] In some embodiments, such as Figure 4 As shown, the first compartment 310 can be located on the main body 100, and the second compartment 320 can be located on the chassis 200; in some other embodiments, such as Figure 5 , 6 As shown, both the first compartment 310 and the second compartment 320 are located on the main body 100. Correspondingly, the first suction device 400 and the second suction device 500 can be simultaneously located on the main body 100, or the first suction device 400 can be located on the main body 100 and the second suction device 500 can be located on the chassis 200, or even the first suction device 400 and the second suction device 500 can be located outside the cleaning device 10. This application does not impose any limitations on these aspects.

[0125] Regarding how to form the first warehouse 310 and the second warehouse 320, as follows: Figures 4-6 As shown, in some embodiments, the cleaning device 10 may include a first housing 310a and a second housing 320a. The first housing 310a has the aforementioned first compartment 310, and the second housing 320a has the aforementioned second compartment 320. The first housing 310a can be fixed to the outside of the second housing 320a by assembly (e.g., ...). Figure 5 (as shown); or, the first housing 310a is disposed on the main body 100, and the second housing 320a is disposed on the chassis 200 (as shown). Figure 4 (As shown). At this time, the first housing 310a and the second housing 320 are independent of each other, so they can be as shown. Figure 4 The parts shown are assembled and fixed to the main body 100. Here, assembly refers to installation and fixing them together using snaps, fasteners, or other methods; alternatively, they can be assembled and fixed as shown in the diagram. Figure 4 As shown, they are separated and placed on the main unit 100 and the chassis 200 respectively. Or, as... Figure 6 As shown, the cleaning device 10 includes a first housing 310a and a second housing 320a, with at least a portion of the first housing 310a nested within the second housing 320a. For example, as... Figures 7-10As shown, part of the inner wall of the second shell 320a and part of the outer wall of the first shell 310a form the second bin 320; the first shell 310a forms the first bin 310 (as shown in Figure 7 , 8 Alternatively, part of the inner wall of the first shell 310a and part of the inner wall of the second shell 320a jointly form the first bin 310 (as shown in Figure 9 , 10 .

[0126] In addition, it should be noted that the external liquid described in the embodiments of the present application can be sewage (sewage includes solid-liquid mixture, wastewater), or clean water. The first suction device 400 of the embodiments of the present application mainly provides driving power for the external liquid to enter the first bin 310. Wherein, the external refers to the part outside the first bin 310 and the second bin 320.

[0127] When the suction liquid is wastewater or solid-liquid mixture, the water tank 300 is a wastewater tank, and the first suction device 400 can recycle the sewage generated in the cleaning process of the cleaning equipment 10 to the wastewater tank, to facilitate the subsequent processing of the user.

[0128] When the suction liquid is clean water, at this time, the first suction device 400 can suck the external clean water into the first bin 310. When the first bin 310 and the second bin 320 form a wastewater tank, the clean water can clean the first bin 310 and / or the second bin 320, to maintain the water tank.

[0129] Hereinafter, the external liquid is taken as an example of solid-liquid mixture or wastewater.

[0130] As shown in Figures 4-6As shown, the first suction device 400 can be used to suck the dirt outside the cleaning device 10 (including solid-liquid garbage, sewage, etc.) into the first bin 310 during the cleaning process of the cleaning device 10, so as to recycle the stains, oil stains or impurities on the ground. Among them, the cleaning device 10 can also suck the mixture of solid garbage and sewage outside into the first bin 310, which is not limited by the present application. The chassis 200 of the cleaning device 10 is provided with a cleaning piece 210 for cleaning the surface to be cleaned, which can be a cleaning component such as a roller brush. One end of the main body 100 is provided with a handle 110 for the user to hold, and the user holds the handle 110 to drive the main body 100 to push the chassis 200 forward and backward or turn. The first bin 310 is arranged in the main body 100, and the second bin 320 is in communication with the first bin 310. The first suction device 400 is in communication with the first bin 310, so that the first suction device 400 can provide the power to drive the liquid outside into the first bin 310. For example, the first suction device 400 can be a fan or other large-flow negative pressure source capable of providing negative pressure, so as to be able to suck the liquid outside into the first bin 310. The second bin 320 is in communication with the first bin 310, and the second bin 320 can be understood as being indirectly communicated with the first suction device 400 through the first bin 310. When the communication channel between the first bin 310 and the second bin 320 is cut off, the first suction device 400 is only in communication with the first bin 310.

[0131] As shown, Figures 4-10 The first bin 310 and the second bin 320 have a partition (the partition can be the bottom wall and / or the side wall of the first bin 310) therebetween, so that the first bin 310 and the second bin 320 are relatively independent, and the partition blocks the liquid in the second bin 320 from flowing back to the first bin 310. The communication between the first bin 310 and the second bin 320 means that there is a channel for liquid circulation between them, wherein the "channel" includes but is not limited to holes, pipes, gaps, etc., and the channel is used to allow the liquid in the first bin 310 to enter the second bin 320.

[0132] The second suction device 500 is in communication with the second bin 320, and the second suction device 500 can provide the power to drive the liquid in the first bin 310 into the second bin 320, so as to further block the liquid in the second bin 320 from flowing back to the first bin 310 from the channel for liquid circulation.

[0133] The embodiment of the present application can reduce the amount of liquid in the first tank 310 or remove the liquid in the first tank 310 by adding the second suction device 500 to drive the liquid in the first tank 310 to the second tank 320, thereby reducing the risk of liquid entering the first suction device 400. It should be noted that the first suction device 400 is used to drive external liquid to the first tank 310, and the suction path is relatively long, and the required suction flow is relatively large; while the second suction device 500 is used to drive the liquid in the first tank 310 to the second tank 320, and the required suction flow can be smaller; when the second suction device 500 is a gas suction device, the second suction device 500 also has a certain risk of liquid entering. However, it can be understood that when facing the same amount of suction liquid, the greater the suction flow, the greater the risk of liquid entering the suction device. Since the required suction flow for driving the liquid in the first tank 310 to the second tank 320 can be smaller, the second suction device 500 with smaller suction flow can be selected, thereby also reducing the risk of liquid entering the second suction device 500. Since the required flow for driving the liquid in the first tank 310 to the second tank 320 can be smaller, the wind resistance of the suction channel communicating with the second suction device 500 can be further increased, for example, some blocking structures that hinder water and / or water vapor from entering the second suction device 500 are added, to further reduce the risk of liquid entering the second suction device 500. How to design the blocking structure to reduce the risk of liquid entering the second suction device 500, and the specific form of the blocking structure is described in detail in the subsequent embodiments.

[0134] In addition, the risk of liquid entering the first suction device 400 can also be reduced by adding a blocking structure. Since it is necessary to ensure that the first suction device 400 can always provide a larger suction flow to maintain the state of suctioning external liquid to the first tank 310, the design of the blocking structure can be slightly simple to appropriately reduce the wind resistance and reduce the risk of water entering the first suction device 400, while also trying not to affect the first suction device 400 to always provide a larger suction flow.

[0135] In some embodiments, the second suction device 500 includes a gas suction device, the first tank 310 and the second tank 320 are communicated through the liquid leakage structure 312, and the cross-sectional area of the suction port of the gas suction device 500 is similar to the cross-sectional area of the liquid leakage structure. Similar means that the area difference is small. For example, less than 20 square millimeters. By setting the cross-sectional areas of the two to be similar, the "suction force" of the second suction device 500 can act on the liquid leakage structure 312 with a 1:1 ratio, thereby improving the flow rate of the liquid in the first tank 310 entering the second tank 320 through the liquid leakage structure 312.

[0136] In the embodiments of the present application, since the first suction device 400 directly communicates with the first tank 310, and the first tank 310 has liquid recycled from the outside, during the operation of the cleaning device 10, especially when the liquid in the first tank 310 is filled or the main body 100 is in an inclined state or a lying state, the liquid in the first tank 310 is easy to directly enter the first suction device 400 from the first tank 310. By providing the second suction device 500, the second suction device 500 communicates with the second tank 320, and the second suction device 500 provides the driving force for the liquid in the first tank 310 to enter the second tank 320, so that the liquid in the first tank 310 is always less. In this way, it can be avoided that the liquid in the first tank 310 enters the first suction device 400 when the main body 100 shakes, inclines, or lies down, thereby reducing the risk of liquid entering the first suction device 400, causing secondary pollution, and even damage. Moreover, the second suction device 500 can effectively prevent the liquid in the second tank 320 from flowing back to the first tank 310, thereby avoiding the risk of failure of the first suction device 400.

[0137] It should be noted that the first suction device 400 and the second suction device 500 are independent suction sources, and the suction power of the two can be independently controlled. For example, when the first suction device 400 provides driving power to drive the solid-liquid mixture, sewage, or clean water to enter the first tank 310, the suction power can be adjusted due to environmental factors, while the second suction device 500 can maintain a relatively high power to ensure that the liquid is sucked from the first tank 310 into the second tank 320 under any circumstances.

[0138] In some embodiments, as shown in Figure 11 The cleaning device 10 can further include a posture detection device 700 and a control device 600. The posture detection device 700 is configured to detect a current motion state parameter of the cleaning device 10. The control device 600 is connected (which can be wired or wireless) to the posture detection device 700, the first suction device 400, and / or the second suction device 500. The control device 600 is configured to adjust the operating parameters of the first suction device 400 and / or the second suction device 500 according to the current motion state parameter of the cleaning device 10 detected by the posture detection device 700, thereby reducing the possibility of liquid in the first tank 310 entering the first suction device 400 and / or the second suction device 500.

[0139] The motion state parameter detected by the posture detection device 700 includes at least one of the following: an inclination angle of the main body 100 relative to the ground, an inclination angular velocity of the main body 100 relative to the ground, an inclination angular acceleration of the main body 100 relative to the ground, an acceleration of the main body 100, a speed of the main body 100, or a height of the first tank 310 relative to the ground.

[0140] For example, the attitude detection device 700 detects at least one of the motion state parameters of the cleaning equipment 10, including the angle between the main body 100 and the chassis 200, the angular velocity between the main body 100 and the chassis 200, the angular acceleration between the main body 100 and the chassis 200, the motion speed of the cleaning equipment 10, the motion acceleration of the cleaning equipment 10, and the height of the first compartment 310 from the ground. In this embodiment, the posture detection device 700 can be used to determine whether the cleaning device 10 is currently in an upright, tilted, or lying position. The posture detection device 700 can also detect the speed or acceleration of the cleaning device 10 during operation. If the main body 100 is in a lying position or the cleaning device 10 shakes too much (i.e., accelerates too much) or moves too fast during operation, in order to protect the first suction device 400 and the second suction device 500, the control device 600 can adjust the operating parameters of the first suction device 400 and / or the second suction device 500 according to the current motion state parameters detected by the posture detection device 700. That is, the suction force, operating power, operating time, or operating current of the first suction device 400 or the second suction device 500, etc., to reduce the risk that liquid in the first chamber 310 and / or the second chamber 320 will enter the first suction device 400 and / or the second suction device 500 when the cleaning device 10 is shaking, tilted, or the main body 100 is in a lying position.

[0141] In some implementations, such as Figure 1 As shown, the cleaning device 10 includes a water tank 300, with a first chamber 310 and a second chamber 320 formed within it. The water tank 300 serves as a wastewater tank if it collects sewage. When the cleaning device 10 is in an upright position, the first chamber 310 is positioned above the second chamber 320. The water tank 300 is detachably mounted on the main body 100. A first suction device 400 and a second suction device 500 are located on the main body 100, allowing the first suction device 400 to draw external liquid into the first chamber 310 of the water tank 300, and the second suction device 500 to draw liquid from the first chamber 310 into the second chamber 320.

[0142] In some implementations, such as Figure 7 As shown, the cleaning equipment 10 may further include a first detection component 361. The control device 600 is connected to the first detection component 361. The first detection component 361 is disposed in the first compartment 310 and is used to detect the contents information of the first compartment 310, so that the control device 600 can adjust the operating parameters of the first suction device 400 and / or the second suction device 500 according to the contents information detected by the first detection component 361. The contents information may include solid waste volume information, liquid level information, and water presence or absence information, etc.

[0143] For example, the first bin 310 can be provided with a filter screen 352 to form a solid-liquid separation bin, and the content information can indicate the capacity of solid waste.

[0144] For example, the first detection assembly 361 in the first bin 310 is arranged above the first bin 310.

[0145] For example, the first detection assembly 361 in the first bin 310 is arranged at the rear side above the first bin 310. In this way, if the first detection assembly 361 is triggered by liquid when the cleaning device is in a lying state, it indicates that the first suction device 400 has a risk of liquid ingress.

[0146] Further, a prompting device (not shown) can also be included, which is electrically connected to the first detection assembly 361, so that when the amount of dirt in the first bin 310 reaches a preset value or is triggered, the prompting device can notify the user to replace or clean the first bin 310 and / or the second bin 320, so as to reduce the possibility of safety hazards caused by liquid backflow in the first bin 310 and the second bin 320.

[0147] For example, the control device 600 is connected to the first detection assembly 361, the first suction device 400 and / or the second suction device 500. When the amount of dirt in the first bin 310 reaches a preset value or is triggered, the control device 600 can adjust the operating parameters of the first suction device 400, so that the suction force of the first suction device 400 is reduced or turned off, reducing the possibility of liquid in the first bin 310 entering the first suction device 400.

[0148] At the same time, when the amount of dirt in the first bin 310 is large (for example, there is a large amount of solid waste in the first bin 310), it will to some extent cause the liquid in the first bin 310 to be difficult to enter the second bin 320. Therefore, in this scenario, the operating parameters of the second suction device 500 can be adjusted by the control device 600 to increase the suction force of the second suction device 500, so that the second suction device 500 provides greater suction force to more fully suck the liquid in the first bin 310 to the second bin 320.

[0149] It should be noted that the detection of the amount of dirt in the first bin 310 by the first detection assembly 361 includes detection of solid objects, viscous objects or liquid in the first bin 310, and the specific detection method includes but is not limited to detection of dirt height, detection of dirt weight, or even direct knowledge of the amount of dirt through vision. The present application is not limited.

[0150] In an embodiment, the cleaning device comprises a second detection assembly 362 configured to detect the content information of the second tank. For example, when the amount of dirt in the second tank 320 reaches a preset amount, the control device 600 can adjust the operating parameters of the second suction device 500, so that the suction force of the second suction device 500 is reduced or turned off, thereby reducing the possibility of liquid in the second tank 320 entering the second suction device 500. In this case, in order to reduce the probability of water entering the first suction device 400, when the amount of dirt in the second tank 320 reaches the preset amount, the control device 600 can also reduce or turn off the suction force of the first suction device 400, thereby avoiding continuous increase of liquid in the second tank 320.

[0151] For example, the operating parameters of the first suction device 400 and the second suction device 500 include at least one of the following: operating power, operating time, operating voltage, operating duty cycle current, so that the control device 600 can control the working time and suction force of the first suction device 400 and the second suction device 500 through the operating parameters, so that the liquid outside can enter the first tank 310, the liquid in the first tank 310 can enter the second tank 320, and under the control of the control device 600, the operating parameters of the first suction device 400 and the second suction device 500 can be flexibly adjusted according to the current state of the cleaning device 10 or the amount of dirt in the first tank 310 and / or the second tank 320. In particular, when the amount of liquid dirt is large, the suction device can be turned off or the suction force of the suction device can be reduced (the greater the suction force, the greater the required operating power, and the greater the operating power, the greater the risk of liquid entering the suction device), thereby timely protecting the first suction device 400 and the second suction device 500.

[0152] In another aspect, since the operating parameters of the second suction device 500 can be flexibly adjusted according to the amount of dirt in the first tank 310, when the amount of dirt in the first tank 310 is small, the operating power of the second suction device 500 can be small, and when the amount of dirt in the first tank 310 is large, the operating power of the second suction device 500 can be increased. By matching the amount of dirt in the first tank 310 with the operating parameters of the second suction device 500, the operating parameters of the second suction device 500 are dynamically adjusted, thereby avoiding the problem that the second suction device 500 always operates at a large power and the operating noise is always large, reducing the influence of working noise on user experience, and effectively improving user experience.

[0153] It should be noted that, in order to clearly indicate the orientation, the front side, the rear side, the left side and the right side of the cleaning device 10 are defined. Figure 1As shown, the front side refers to the side of the cleaning device 10 that is moving forward when not turning; the rear side is the side opposite to the front side, that is, the side of the cleaning device 10 that is facing away from the direction of travel when not turning; the left side is the left-hand side when the user is standing facing forward; and the right side is the right-hand side when the user is standing facing forward. For the main unit 100, the front side refers to the side of the main unit 100 that swings forward, and the rear side refers to the side of the main unit 100 that swings backward. The angle of the swing of the main unit 100 will change. When the main unit 100 is in an upright position (e.g., ...), the angle of the swing will change. Figure 1 When the front side is the side of the cleaning device 10 in a non-turning state, the front side is the side facing forward. When the main body 100 is in a reclining state (e.g.) Figure 3 When the front side is the upper side of the main body 100 at this time, the rear side is the lower side of the main body 100 at this time.

[0154] In some embodiments, see Figures 4-10 The first chamber 310 and the second chamber 320 are connected by a leakage structure 312, allowing liquid in the first chamber 310 to enter the second chamber 320. The leakage structure 312 can be a leakage hole, leakage channel, or leakage gap between the first chamber 310 and the second chamber 320, and this application is not limited thereto. It should be noted that the leakage area formed by the leakage structure 312 can be as small and concentrated as possible; for example, the ratio of the area of ​​the leakage structure 312 to the cross-sectional area of ​​the water tank 300 is less than 1 / 4, or less than 1 square centimeter, or the cross-sectional area of ​​the leakage structure 312 is less than 1 / 4 of the bottom area of ​​the first chamber 310. This design allows the remaining portion of the bottom wall of the first housing 310a to isolate the first chamber 310 and the second chamber 320. The suction force of the second suction device 500 is concentrated on the smaller leakage structure 312, which can quickly draw the liquid in the first chamber 310 into the second chamber 320. This reduces the risk of liquid flowing back from the second chamber 320 to the first chamber 310 or the risk of liquid surging back into the first chamber 310 when the cleaning device 10 is shaken. This ensures that most of the liquid remains in the second chamber 320, reducing the amount of liquid remaining in the first chamber 310, and thus reducing the risk of liquid ingress into the first suction device 400.

[0155] It should be noted that when the first chamber 310 is above the second chamber 320, the force that causes the liquid in the first chamber 310 to enter the second chamber 320 may include the gravity of the liquid and the suction force provided by the second suction device 500.

[0156] In some embodiments, the leakage structure 312 may be disposed on the rear side of the first compartment 310. In this way, when the main body 100 is tilted backward or laid down, the leakage structure 312 located on the rear side of the first compartment 310 can be positioned at the lowest point of the first compartment 310, so that the liquid in the first compartment 310 can flow into the second compartment 320 more conveniently during use or when lying down.

[0157] In some embodiments, the liquid leakage structure 312 can be arranged at the lower part of the first tank 310. Wherein, the lower part of the first tank 310 refers to the side of the first tank 310 closer to the bottom wall of the base 200 or the bottom wall, and the arrangement of the liquid leakage structure 312 at the lower part can make the liquid leakage structure 312 be at the lowermost part of the first tank 310 when the main body 100 is tilted or upright, so that all the liquid in the first tank 310 can flow into the second tank 320 through the liquid leakage structure 312.

[0158] In some embodiments, the liquid leakage structure 312 is arranged at the lower part of the rear side of the first tank 310, and in this case, no matter whether the main body 100 is tilted, upright or laid down, the liquid leakage structure 312 can be ensured to be at the lowermost part of the first tank 310 in the current state, so that all the liquid in the first tank 310 can flow into the second tank 320 through the liquid leakage structure 312.

[0159] In an optional embodiment, referring to Figure 12 The maximum size of the liquid leakage structure 312 in the front-rear direction is smaller than the minimum size in the left-right direction, which can be closer to the rear side while ensuring the flow efficiency of the liquid leakage structure 312. For example, the liquid leakage structure 312 can be flat.

[0160] In an optional embodiment, the number of the liquid leakage structure 312 is one or several.

[0161] In the embodiments of the present application, the second suction device 500 can be a gas suction device such as a vacuum pump or a fan, or a liquid suction device such as a water pump or a peristaltic pump. Of course, the present application is not limited thereto, and any device that can provide power to drive the liquid in the first tank 310 to the second tank 320 can be used. Hereinafter, the second suction device 500 is taken as a gas suction device as an example for description.

[0162] In some embodiments, the second suction device 500 includes a gas suction device 500, wherein the gas suction device 500 is in communication with the second tank 320 and is used to suck the gas in the second tank 320 to form a negative pressure in the second tank 320. In this way, in addition to the liquid in the first tank 310 flowing into the second tank 320 under the action of gravity, the negative pressure generated by the gas suction device 500 can also provide a certain auxiliary force to drive the liquid from the first tank 310 to the second tank 320. The gas suction device 500 can be a vacuum pump, an air pump, a fan or any device that can suck gas.

[0163] As Figures 4-6As shown, the first suction device 400 is in communication with the first bin 310 through the first suction passage 311, and the second suction device 500 is in communication with the second bin 320 through the second suction passage 321, so that the first bin 310 can generate a negative pressure under the action of the first suction device 400, so that external liquid can enter the first bin 310, and then the second bin 320 can suck the liquid in the first bin 310 into the second bin 320 under the action of the second suction device 500. For example, Figure 4 , 5 As shown, the second suction passage 321 is a suction interface; or, as shown, Figure 6 the second suction passage 321 is a gas passage.

[0164] It can be understood that when the first suction device 400 and the gas suction device 500 are in a working state, the negative pressure of the first bin 310 at the communication position of the first bin 310 and the second bin 320 can be less than the negative pressure of the second bin 320, so that the liquid in the first bin 310 can flow smoothly into the second bin 320; at the same time, due to the existence of the negative pressure difference, the dirt in the first bin 310 can enter the second bin 320 well, and due to the fluidity of the liquid, the liquid in the second bin 320 will not flow back to the first bin 310 when the cleaning device 10 is tilted, laid down, or shaken, and the first suction device 400 can be effectively protected.

[0165] In some embodiments, further, a filter can be arranged in the first bin 310 to filter solid waste in the dirt and retain the solid waste in the first bin 310, and the liquid in the dirt enters the second bin 320 under the action of the negative pressure of the gas suction device and the action of gravity. How to design the filter in the first bin 310 and the specific form of the filter are described in detail in subsequent embodiments.

[0166] In the embodiments of the present application, compared with the related art, the cleaning device 10 additionally provides the second suction device 500, when the second suction device 500 is a gas suction device 500, similar to the first suction device 400, the gas suction device 500 also faces the problem of possible water damage, therefore, to further reduce the risk of liquid entering the gas suction device 500 (second suction device 500), the present application provides the following solutions:

[0167] In some embodiments, referring to Figures 4-10 , the second suction passage 321 includes an air inlet 321b and an air outlet 321a, wherein the air inlet 321b is in communication with the second bin 320, and the air outlet 321a is in communication with the gas suction device 500 (second suction device 500), and the shape of the second suction passage 321 is not limited herein.

[0168] For example, as shown,Figures 4-10 As shown, the air inlet 321b of the second suction passage 321 can be located at the front side of the second tank 320. In this way, when the cleaning device 10 is in the lying state, the air inlet 321b can be as far away from the liquid surface in the second tank 320 as possible, so as to reduce the probability of liquid in the second tank 320 being sucked into the air inlet 321b (as shown on the left). At the same time, the farther the air inlet 321b is from the liquid surface in the second tank 320 when the cleaning device 10 is lying down, the greater the volume of the second tank 320 that can be utilized. For example, when the cleaning device 10 is in the lying state, if the air inlet 321b is arranged at the front side of the second tank 320, the height of the liquid entering the second tank 320 can approach the front side of the second tank 320, and if the air inlet 321b is arranged at the middle of the second tank 320, in order to reduce the probability of liquid entering the first suction device 400 from the air inlet 321b, the height of the liquid entering the second tank 320 can only be controlled to be lower than the middle. The former can accept a higher liquid height, thereby resulting in a smaller liquid storage capacity of the second tank 320 than when the air inlet 321b is arranged at the front side of the second tank 320. Therefore, arranging the air inlet 321b at the front side of the second tank 320 can increase the effective volume of the second tank 320. Figure 13

[0169] In some embodiments, as shown in Figures 4-10 , the air inlet 321b of the second suction passage 321 is located above the second tank 320, where above refers to the overall upper side of the second tank. In this way, the air inlet 321b can be away from the liquid surface in the second tank 320, so as to reduce the probability of liquid in the second tank 320 being sucked into the second suction passage 321.

[0170] In some embodiments, as shown in Figure 12 , 13 , the maximum dimension of the air inlet 321b in the front-rear direction of the main body 100 is smaller than the minimum dimension of the air inlet 321b in the left-right direction of the main body 100. For example, the air inlet 321b can be flat. If the position of the air inlet 321b is fixed, the shape of the air inlet 321b is arranged in this way, which is equivalent to the lowest point of the opening of the air inlet 321b being as high as possible in the lying state. In this way, at the same liquid level, the lower side of the air inlet 321b can be farther away from the liquid surface in the second tank 320, so as to reduce the probability of liquid in the second tank 320 entering the second suction passage 321. At the same time, the farther the air inlet 321b is from the liquid surface in the second tank 320 when the cleaning device 10 is lying down, the greater the volume of the second tank 320 that can be utilized. For example, as shown in Figure 13 ​As shown, in the lying state of the cleaning device 10, when the air inlet 321b is flat, the height of the liquid entering the second chamber 320 can be closer to the front side of the second chamber 320. If the air inlet 321b is arranged in the second chamber 320 in a manner that the thickness of the second chamber 320 increases in the front-rear direction, i.e., the opening of the air inlet 321b is in the height direction in the lying state, it is equivalent to lowering the opening position. At this time, in order to reduce the probability of liquid entering the second suction device 500 from the air inlet 321b, the height of the liquid entering the second chamber 320 can only be lower than the opening position, and the effective volume of the second chamber 320 will be reduced accordingly. Therefore, arranging the air inlet 321b in a flat manner can also increase the effective volume of the second chamber 320.

[0171] It should be noted that the second suction passage 321 as a whole can also be flat.

[0172] In addition, the air inlet 321b and / or the second suction passage 321 are also located on the front side and / or above the second chamber 320, which can further reduce the probability of liquid entering the air inlet 321b and increase the effective volume of the second chamber 320.

[0173] In an optional embodiment, as shown in Figure 14 As shown, the cross-sectional area of the second suction passage 321 can gradually decrease from the air inlet 321b to the air outlet 321a. In this way, the air inlet 321b can be as large or wide as possible in the limited space, which can reduce the probability of the air inlet 321b being completely blocked by liquid. Even if the air inlet 321b is partially blocked by liquid, since the flowability of gas is greater than that of liquid, the gas suction device can still perform gas suction through the part of the air inlet 321b that is not blocked by liquid during suction. Therefore, the second suction device 500 can still work in this way, thereby reducing the possibility of the second suction device 500 being disabled due to partial water entering the air inlet 321b. In addition, since the cross-sectional area of the second suction passage 321 gradually decreases in the suction direction of the second suction passage 321, even if liquid enters the second suction passage 321 through the air inlet 321b, the liquid that is shaken into the second suction passage 321 is likely to hit the inner wall of the second suction passage 321 and be blocked by the inner wall of the second suction passage 321, and is not easy to directly enter the gas suction device from the air outlet 321a.

[0174] In an optional embodiment, as shown in Figure 15As shown, the second suction passage 321 comprises at least one guide wall 321h for guiding the airflow in the second suction passage 321 to flow along a curved path from the air inlet 321b to the air outlet 321a. Wherein, the guide wall 321h forms a curved path in the second suction passage 321, so that even if water vapor enters the second suction passage 321 through the air inlet 321b, the water vapor needs to pass through the curved path in the second suction passage 321 to reach the air outlet 321a; that is, the path of the water vapor from the air inlet 321b to the air outlet 321a is lengthened, which undoubtedly increases the difficulty of the water vapor entering the second suction device 500 after finally reaching the air outlet 321a. In addition, the water vapor can also play a role in water vapor separation and water vapor shielding when passing through the guide wall 321h, preventing the water vapor from being directly sucked into the second suction passage 321.

[0175] In other embodiments, the guide wall 321h can be curved on the side wall of the second suction passage 321; or the second suction passage 321 comprises a curved side wall, which forms the guide wall 321h.

[0176] In some embodiments, referring to Figures 14-17 , the second suction passage 321 is spaced apart and staggered in the suction direction by a plurality of partitions 321c, and the length direction of the partition 321c can extend substantially along the left-right direction of the main body 100; wherein the partition 321c forms the above-mentioned guide wall 321h, and the partition 321c is used to block the liquid in the second chamber 320 from flowing into the air outlet 321a from the second suction passage 321, reducing the possibility of the liquid in the second chamber 320 entering the gas suction device 500.

[0177] In some embodiments, referring to Figures 14-16 , the partition 321c is provided with a flow guide opening 321d, or the partition 321c and the side wall of the second suction passage 321 are provided with a flow guide opening 321d, and at least two flow guide openings 321d are staggered distributed, and the flow guide opening 321d and the partition 321c are used to guide the airflow to flow along a curved path to prevent the liquid in the second chamber 320 from entering the gas suction device 500.

[0178] For example, the partition 321c can be provided with an opening, and the opening forms the above-mentioned flow guide opening 321d; or one end of the partition 321c is connected with the inner wall of the second suction passage 321, and the other end has a gap with the inner wall, and the gap is staggered distributed, and the gap forms the above-mentioned flow guide opening 321d.

[0179] In an alternative embodiment, please refer to the accompanying Figure 15As shown, one of the adjacent two baffles 321c forms a flow guide opening 321d at the left end of the baffle 321c, and the other of the adjacent two baffles 321c forms a flow guide opening 321d at the right end of the baffle 321c, so that the two flow guide openings 321d are staggered. In this way, the gas flow path can be as long as possible, thereby greatly improving the water vapor separation effect.

[0180] In some embodiments, as shown in Figure 16 , 17 At least one of the baffles 321c is provided with at least one first opening 321k, which is arranged at the middle or both ends of the baffle 321c, and at least one other of the baffles 321c is provided with at least two second openings 321m, which are staggered with the first openings 321k, wherein the first openings 321k and the second openings 321m form the flow guide openings 321d described above. That is, more than one opening can be provided on the baffle 321c to reduce the wind resistance of the gas suction device when suctioning the second suction passage 321; and the baffles 321c provided with multiple openings can be staggered between the openings of adjacent baffles 321c to form a curved path of the gas flow. The sizes of the first openings 321k and the second openings 321m can be different.

[0181] In some embodiments, as shown in Figures 14-16 , 18, the baffles 321c can be arranged obliquely, and the flow guide openings 321d can be arranged at the lowest part of the baffles 321c, which can facilitate the baffles 321c to block the liquid entering the second suction passage 321, and also ensure that the liquid entering the second suction passage 321 will flow out due to gravity when the main body 100 is inclined or upright.

[0182] In some embodiments, as shown in Figures 14-18 Between each adjacent two baffles 321c, a unit gas flow passage 321e is formed, and the cross-sectional area of each unit gas flow passage 321e gradually decreases along the gas flow direction. If liquid enters the unit gas flow passage 321e, the gradually decreasing cross-sectional area of the gas flow passage along the gas flow direction can make the liquid entering the unit gas flow passage 321e easily impact on the inner wall of the unit gas flow passage 321e, thereby forming a certain blocking effect on the liquid, so that the liquid can be blocked at a position with a smaller cross-sectional area, thereby reducing the probability of the liquid entering the gas suction device 500.

[0183] In some embodiments, as shown in Figure 14 , 15As shown, in each pair of adjacent unit airflow channels 321e, the minimum cross-sectional area of ​​the one closer to the air inlet 321b is smaller than the maximum cross-sectional area of ​​the other. This arrangement allows the size of the cross-sectional area of ​​the airflow channel to change periodically. This arrangement allows the airflow velocity entering the unit airflow channel 321e to slow down when entering the area with a larger cross-sectional area. As a result, the liquid mixed in the airflow can fall under the action of gravity, which can assist in gas-liquid separation and reduce the probability of liquid entering the gas suction device.

[0184] For example, such as Figure 15 As shown, the partition 321c includes a first partition 3211c and a second partition 3212c that are staggered along the suction direction. The second suction channel 321 has a first sidewall 321f and a second sidewall 321g that are arranged opposite each other in the left-right direction. The first partition 3211c is disposed on the first sidewall 321f of the second suction channel 321 and inclined downward toward the second sidewall 321g. The second partition 3212c is disposed on the second sidewall 321g of the second suction channel 321 and inclined downward toward the first sidewall 321f, so that the first partition 3211c and the second partition 3212c can both be inclined downward and can be staggered in the up-down direction.

[0185] Furthermore, such as Figure 15 As shown, a baffle 3213c may be provided on the partition 321c. The baffle 3213c is set at an angle to the airflow direction to block liquid from entering the second suction channel 321. By setting the baffle 3213c, at least part of the suction airflow can directly impact the baffle 3213c. Since the airflow carries water vapor, the water vapor impacts the baffle 3213c and can flow down along the extension direction of the baffle 3213c. In this way, the risk of liquid entering the second suction device 500 through the second suction channel 321 can be further reduced.

[0186] For example, the extending direction of the baffle 3213c can be substantially perpendicular to the airflow direction to minimize the possibility of liquid entering the second suction channel 321. In some other embodiments, the extending direction of the baffle 3213c can form an acute angle with the airflow direction, as long as the baffle 3213c can block the liquid in the airflow.

[0187] In some embodiments, the first sidewall 321f and / or the second sidewall 321g may be curved walls to form curved airflow channels.

[0188] In some embodiments, such as Figure 16As shown, the plurality of partitions 321c are arranged at the portion of the second suction passage 321 close to the air inlet 321b, and the portion of the second suction passage 321 close to the air outlet 321a is not provided with any partition; such arrangement can make the front portion of the second suction passage 321 close to the air inlet 321b mainly function to prevent liquid from entering the second suction passage 321, and the rear half of the second suction passage 321 close to the air outlet 321a forms a larger space, so that liquid entering the rear half of the second suction passage 321 by accident can slow down under the action of the larger space, thereby returning to the second chamber. In this case, the first side wall 321f and the second side wall 321g of the suction passage 321 can be arranged as straight walls.

[0189] In some embodiments, referring to Figure 17 、 Figure 18 , the partitions 321c can be detachably connected with the inner wall of the second suction passage 321, so as to clean the partitions 321c and the second suction passage 321, and when the second suction passage 321 is flat, cleaning the inside of the second suction passage 321 is particularly difficult, and it is almost impossible to clean when there are partitions, therefore, the partitions are arranged to be detachable, so that the user can clean them after detaching them.

[0190] Further, referring to Figures 17-18 , the second suction passage 321 is further detachably provided with a partition rack 322, the partition rack 322 is provided with a plurality of partitions 321c as described above, the partition rack 322 is plate-shaped, and the partition rack 322 can form the second suction passage 321 after being installed in place, and then the partition rack 322 can be detached from the second suction passage 321 for cleaning, which is simple and practical. Especially when the second suction passage 321 is flat, the cleaning of the second suction passage 321 is particularly difficult, therefore, the partition rack 322 is used to detach the partitions as a whole, which is convenient for detaching and cleaning.

[0191] Specifically, the arrangement of the partition rack 322 at least includes two modes as shown in Figure 17 、 18 . As shown in Figure 17 , the partition rack 322 is arranged to be pullable inside the second suction passage 321, the partition rack 322 is provided with two support strips respectively connected with the left and right ends of a plurality of partitions 321c as described above, and the partition rack 322 can be inserted or pulled out from below along the second suction passage 321. Alternatively, as shown in Figure 18 , the partition rack 322 is a flat plate, and the partitions are all arranged on the flat plate, one side of the flat plate on which the partitions are arranged forms part of the inner wall of the second suction passage 321, and the user can take down the flat plate and then take down the partitions to open the second suction passage 321 as a whole, which is convenient for cleaning.

[0192] In some embodiments, as shown in Figure 15 、 16 , the cleaning device 10 can be provided with a third detection assembly 363 for detecting whether water enters the second suction passage 321 to reduce the risk of failure of the gas suction device 500 caused by entering liquid; when it is detected that water enters the second suction passage 321, the gas suction device can be controlled to be turned off or the power of the gas suction device is reduced to avoid the liquid in the second suction passage 321 entering the gas suction device as much as possible. Optionally, the third detection assembly 363 can be an electrode type sensor or a photoelectric type sensor.

[0193] Specifically, as shown in Figure 15 、 16 , the third detection assembly 363 can include a detection electrode 323, wherein the number of detection electrodes 323 can be two, and both of the two detection electrodes 323 are arranged in the second suction passage 321; or one of the detection electrodes 323 is arranged in the second suction passage 321, and the other detection electrode 323 is arranged at the upper part of the second tank 320. The detection electrode 323 is mainly used to detect whether water enters the second suction passage 321.

[0194] It can be understood that the control device 600 can be connected with the third detection assembly 363, for controlling the start-stop or power size of the gas suction device 500 according to the information of whether water enters the second suction passage 321 detected by the third detection assembly 363, to reduce the possibility of damage of the gas suction device 500 caused by water entering. Specifically, when a certain amount of water enters the second suction passage 321, the two detection electrodes 323 are conducted, and a water entering signal is sent, and the control device 600 controls the gas suction device 500 to be turned off or the power to be reduced; when a certain amount of water flows out of the second suction passage 321, the two detection electrodes 323 are disconnected, and a no-water signal is sent, and the control device 600 controls the gas suction device 500 to be turned on or the power to be increased.

[0195] In an optional embodiment, as shown in Figure 7 , the second tank 320 is provided with a second detection assembly 362 for detecting the liquid level information in the second tank 320. In this embodiment, the second detection assembly 362 is a liquid level sensor or a water presence sensor. At this time, the liquid level information includes specific information of the liquid level in the second tank 320, or information of whether water reaches the second detection assembly 362 instantaneously in the case of shaking, tilting, etc.

[0196] For example, the installation position of the second detection assembly 362 can be lower than the air inlet 321b of the second suction passage 321, and / or the installation position of the second detection assembly 362 is located behind the air inlet 321b of the second suction passage 321. The second detection assembly 362 can trigger the water signal when the liquid or liquid level reaches the installation position, at which time the control device 600 is used to control the gas suction device to be closed or to reduce the power. Therefore, the position of the second detection assembly 362 needs to be set lower than the air inlet 321b, and / or the installation position of the second detection assembly 362 is located behind the air inlet 321b of the second suction passage 321, which is set in this way. The second detection assembly 362 can be closer to the liquid surface than the air inlet 321b regardless of the upright state or the inclined state, the lying state, so as to trigger the alarm before the liquid enters the air inlet 321b, thereby reducing the probability of the liquid entering the gas suction device from the air inlet 321b.

[0197] The following describes how to form the first bin 310, the second bin 320, and the second suction passage 321 in detail as follows:

[0198] In some embodiments, as shown in Figure 4 , Figure 5 The cleaning device 10 includes a first shell 310a and a second shell 320a, the first shell 310a forms the first bin 310 described above, and the second shell 320a forms the second bin 320 described above. The first shell 310a is fixed to the outside of the second shell 320a by assembly (as shown in Figure 5 The assembly refers to the assembly of the first shell 310a and the second shell 320a by buckling, buckling, clamping, etc. Alternatively, the first shell 310a is arranged on the main body 100, and the second shell 320a is arranged on the chassis 200 (as shown in Figure 4 The gravity of the main body 100 can be reduced, so that the user can perform the pushing or twisting operation on the main body 100 more easily.

[0199] At this time, the first bin 310 and the second bin 320 are independently arranged, and the air outlet 321a of the second suction passage 321 is arranged on the second shell 320 and located at the top of the second bin 320 for interface connection with the second suction device 500.

[0200] In some embodiments, referring to Figures 6-10 The cleaning device 10 includes a first shell 310a and a second shell 320a, at least part of the first shell 310a is nested in the second shell 320a, and the second bin 320 is formed by part of the inner wall of the second shell 320a and part of the first shell 310a (as shown in Figures 6-10); and the first bin 310 is formed in two different ways, i.e., the first bin 310 is formed by the first shell 310a (as shown in Figure 7 、 8 ), or is formed by the partial inner wall of the first shell 310a and the partial inner wall of the second shell 320a (as shown in Figure 9 、 10 ).

[0201] At this time, the first bin 310 and the second bin 320 are both installed on the main body 100, and are formed by nesting the first shell 310a and the second shell 320a. The second suction passage 321 can be entirely arranged on the wall surface of the first shell 310a (as shown in Figure 19 、 20 ) or the wall surface of the second shell 320, i.e., the inner wall of the solid structure. Alternatively, part of the second suction passage 321 is arranged on the wall surface of the first shell 310a and is isolated from the first bin 310, and the other part is formed by the partial outer wall of the first shell 310a and the partial inner wall of the second shell 320 (as shown in Figure 21 ), the partial inner wall of the second shell 320 forming the first bin 310 and the partial inner wall of the second shell 320 forming the second suction passage 321 are different.

[0202] In some embodiments, as shown in Figures 14-16 , the first shell 310a and the second shell 320a are nested, and at this time, the outer wall of the first shell 310a is slotted and surrounded by the inner wall of the second shell 320a to form the second suction passage 321.

[0203] In some embodiments, the air outlet 321a of the second suction passage 321 is arranged on the wall surface of the second shell 320a.

[0204] For example, as shown in Figures 6-10 , 19-21, the first shell 310a is nested in the second shell 320, the first shell 310a forms the first bin 310, the bottom of the first shell 310a and the partial inner wall of the second shell 320 form the second bin 320, and the upper part of the first shell 310a is sealed with the upper part of the second shell 320. The air outlet 321a can be arranged above the second bin 320 in the middle of the second shell 320a and directly suction the top of the second bin 320, or can be arranged at the upper part of the second shell 320a and suction the top of the second bin 320 through the second suction passage 321 formed by the outer wall of the first shell 310a and the inner wall of the second shell 320, and the air outlet 321a is used for docking with the interface of the second suction device 500.

[0205] In some embodiments, as shown in Figures 19-21As shown, the first housing 310a is partially nested inside the second housing 320a, and the air outlet 321a is provided on the wall of the first housing 310a and is located on the part of the first housing 310a that protrudes from the second housing 320a.

[0206] For example, such as Figures 19-21 As shown, this scheme is similar to Figures 7-10 Compared to the previous solution, the upper part of the first housing 310a is not completely nested by the second housing 320a, and an air outlet 321a is provided at the unnested part of the first housing 310a. In this case, the second suction channel 321 is opened inside the solid structure of the first housing 310a, and a connection port between the second suction channel 321 and the second chamber 320 is opened at the bottom of the first housing 310a. The second suction channel 321 inside the first housing 310a is isolated from the first chamber 310a. In this solution, there is no need to process the air outlet 321a on the second housing 320a, which can ensure the integrity of the second housing 320. Since the second housing 320 is mainly used for storing liquid, the integrity of the sidewalls of the second housing 320 can reduce the occurrence of liquid leakage, thereby improving the stability of the second housing 320 in containing liquid.

[0207] In an optional embodiment, the first housing 310a or the second housing 320a is detachably connected to the main body 100. This arrangement allows the user to easily remove the first housing 310a and / or the second housing 320a when it is full of liquid or dirt, for cleaning the contents. The air outlet 321a is sealed and connected to the suction port of the gas suction device 500 located on the main body 100.

[0208] In some other embodiments, such as Figure 21 As shown, when the second suction channel 321 is partially located on the wall of the first housing 310a, the remaining part of the second suction channel 321 is formed by the outer wall of the first housing 310a and the inner wall of the second housing 320a.

[0209] Furthermore, such as Figure 12 , 14 -16, the cleaning device 10 may include a first sealing portion 340a, the first sealing portion 340a being used to seal as described above. Figure 21The remaining part of the second suction channel 321 is formed by the outer wall of the first shell 310a and the inner wall of the second shell 320a. Since there are gaps in the periphery of the remaining part of the second suction channel 321 formed by the outer wall of the first shell 310a and the inner wall of the second shell 320a, water on the rear side of the second tank 320 or water between the gaps of the first shell 310a and the second shell 320a is more likely to enter the suction channel 321. Therefore, by arranging the first sealing part 340a, the suction force of the second suction channel 321 can be concentrated on the air inlet 321b, which facilitates the control of the liquid source and the arrangement of the position of the air inlet 321b, so that the cleaning device 10 has little risk of water entering regardless of the lying state, the upright state, or the inclined state.

[0210] When the part of the first shell 310a is nested in the second shell 320, in order to ensure that the first tank 310 and the second tank 320 are relatively independent (only connected by the liquid leakage structure 312) and sealed, the following design is made:

[0211] In some embodiments, referring to Figure 7 、 8 , a first sealing part 330 is arranged between the first shell 310a and the second shell 320a, and the first sealing part 330 is pressed between the first shell 310a and the second shell 320a to seal the first shell 310a and the second shell 320a circumferentially. At this time, the side wall 310c of the first shell 310a is a complete side wall, and the first sealing part 330 is used to seal the gap between the first shell 310a and the second shell 320a, so that the part of the outer wall of the first shell 310a and the part of the inner wall of the second shell 320a form the second tank 320, and ensure that the liquid in the second tank 320 does not flow out to cause leakage, and the force of the gas suction device 500 can also act on the liquid leakage structure 312.

[0212] In some embodiments, referring to Figures 17-19,21, the side wall 310c of the first shell 310a is an incomplete side wall, i.e. the side wall 310c of the first shell 310a has a gas leakage portion 310d, and a second sealing member 340 is further arranged between the first shell 310a and the second shell 320a, the first sealing member 330 and the second sealing member 340 are arranged in a spaced manner along the height direction of the first shell 310a, and the first sealing member 330 is above the second sealing member 340. Wherein, the gas leakage portion 310d is located between the first sealing member 330 and the second sealing member 340. Due to the existence of the gas leakage portion 310d on the side wall 310c of the first shell 310a, the first bin 310 cannot form a gas-tight state, therefore, the sealing member is used to isolate the first bin 310 and the second bin 320 from the outside world to ensure that the first bin 310 and the second bin 320 form a relatively independent gas-tight state, so that a negative pressure environment can be formed in the first bin 310 and the second bin 320.

[0213] In some embodiments, referring to Figure 9 、 17 -19、21, the opening 325 of the first shell 310a forms the above-mentioned gas leakage portion 310d. It can be understood that when the first shell 310a is taken out of the second shell 320, the first shell 310a is provided with the opening 325, which can facilitate the dumping of dirt in the first bin 310, and improve the user experience.

[0214] In some embodiments, as shown in Figure 22 , the side wall 310c of the first shell 310a is provided with a filter hole 352, and the side filter hole 352 forms the above-mentioned gas leakage portion 310d. The filter hole 352 can perform solid-liquid separation on the dirt in the first bin 310, so that the solid waste remains in the first bin 310, and the liquid falls into the second bin 320 when the first shell 310a is taken out of the second shell 320a. At the same time, compared with the opening 325, the arrangement of the side filter hole 352 can prevent the waste in the first bin 310 from falling when the first shell 310a is taken out of the second shell 320a.

[0215] In some embodiments, as shown in Figures 22-24As shown, the first shell 310a includes at least one movable part 310e, which forms at least the side wall 310c of the first shell 310a. The movable parts 310e are spaced apart from each other or from the side wall 310c of the first shell 310a to form gaps, which are located on the side wall 310c of the first shell 310a and form the air leakage part 310d. Since the movable parts 310e form the side of the first shell 310a, the garbage is not easy to fall off during the process of taking out the second shell 320. At the same time, in order to facilitate the disposal of the garbage in the first bin 310, the side wall is arranged as the movable part 310e to facilitate the operation of the user when the garbage is poured. At the same time, the filter hole 352 can also be arranged on the movable part 310e to further strengthen the solid-liquid separation.

[0216] For example, the first shell 310a can include at least one movable part 310e that is movable relative to each other, such as a sliding connection, a rotating connection (for example, as shown in Figures 22-24 ), or the like. The gaps between the movable parts 310e form the air leakage part 310d.

[0217] In an optional embodiment, as shown in Figures 7-8 , the first shell 310a includes a first body 310f and a second body 310g. The first body 310f is movably assembled on the upper part of the second body 310g, that is, the first body 310f is detachably mounted on the second body 310g. Generally, the first body 310f is mounted with a hipper above it to protect the first suction device 400. A third sealing member 390 is arranged between the first body 310f and the second body 310g to circumferentially seal the first body 310f and the second body 310g; or, as shown in Figure 10 , the first body 310f and the second body 310g are spaced apart in the second shell 320a to form the first bin 310. The first body 310f and the second shell 320a are circumferentially sealed by a fourth sealing member 910, and the second body 310g and the second shell 320a are circumferentially sealed by a fifth sealing member 920.

[0218] In some embodiments, as shown in Figures 14-16As shown in Figure 21, a portion of the outer wall of the first housing 310a and a portion of the inner wall of the second housing 320a together form at least a portion of the second suction channel 321. The second sealing member 340 includes a first sealing portion 340a and a second sealing portion 340b. The first sealing portion 340a surrounds the outside of the second suction channel 321, and the second sealing portion 340b surrounds the first housing 310a circumferentially, with the first sealing portion 340a and the second sealing portion 340b connected. In this configuration, the second sealing member 340 serves both to form the shape of the second suction channel 321 and to isolate the first chamber 310 and the second chamber 320.

[0219] In one alternative implementation, such as Figure 25 As shown, a water leakage notch 312a is provided on the outer side of the side wall 310c of the first housing 310a. The water leakage notch 312a and the inner wall of the second housing 320a form the above-mentioned leakage structure 312. The water leakage notch 312a can be provided on the outer side of the bottom wall of the first housing 310a. The second sealing member 340 is provided with a sealing strip notch. The position of the sealing strip notch corresponds to the position of the water leakage notch 312a. By placing the leakage notch 312a at the sealing notch of the second seal 340, the leakage structure 312 is positioned on the rear side of the main body 100 when the main body 100 is tilted or lying down. This allows the leakage notch 312a to be closer to the rear side and at a lower water level, thus facilitating the flow of liquid from the first chamber 310 into the second chamber 320 and preventing liquid accumulation in the first chamber 310, which could pose a safety hazard to the first suction device 400. Furthermore, this arrangement ensures that after the first housing 310a is removed from the second housing 320a, only one leakage notch 312a remains, making cleaning of the leakage notch 312a easier.

[0220] In an alternative implementation, such as Figure 26 As shown, the leakage structure 312 is disposed on the bottom wall of the first housing 310a, and the second seal 340 is disposed around the leakage structure 312.

[0221] In some embodiments, a radially narrowed portion 326 is circumferentially arranged around the inner wall of the second housing 320a. The inner diameter of the radially narrowed portion 326 is smaller than the inner diameter of the inner wall of the region above the radially narrowed portion 326, so that the lower part of the first housing 310a can abut against the radially narrowed portion 326 (e.g., Figure 27 , 28The lower part of the first shell 310a abuts against the constricted part 326, so that the first shell 310a can be stably installed inside the second shell 320a. At this time, the lower part of the first shell 310a can be flexible and can be in interference fit with the constricted part 326; and the rest of the first shell 310a can be flexible or rigid. Meanwhile, when the lower part of the first shell 310a is provided with the second seal 340, the second seal 340 abuts against the constricted part (as shown in Figure 29 、 30 ), so that the second seal 340 is deformed, and the sealing between the second seal 340 and the second shell 320a is better, and the first chamber 310 and the second chamber 320 are well isolated, so that the first chamber 310 and the second chamber 320 can be relatively independent. In addition, since the lower part of the first shell 310a can have a gap with the part above the constricted part 326 of the second shell 320a, when the first shell 310a is taken out of the second shell 320a, only the friction between the constricted part 326 and the lower part of the first shell 310a needs to be overcome, and after the lower part of the first shell 310a is separated from the constricted part 326 of the second shell 320a, the lower part of the first shell 310a and the inner wall of the second shell 320a are no longer in contact in the subsequent taking-out process, and there is no frictional resistance, so that the first shell 310a can be taken out more conveniently.

[0222] For example, as shown in Figure 28 、 30 , the second shell 320a includes a first inner wall 320b and a second inner wall 320c, the first inner wall 320b is located above the second inner wall 320c, the inner diameter corresponding to the second inner wall 320c is smaller than the inner diameter corresponding to the first inner wall 320b, and the first inner wall 320b and the second inner wall 320c are connected through the constricted part 326.

[0223] In an optional embodiment, as shown in Figure 28 、 30 , the inner diameter of the constricted part 326 gradually decreases along the installation direction of the first shell 310a, so that the first shell 310a can be relatively smooth during installation or taking-out. When the lower part of the first shell 310a is provided with the second seal 340, the lower part of the first shell 310a can abut against the constricted part 326, so that the sealing is better.

[0224] The application further provides a seal, which can be applied to the first seal 330 to the fifth seal 920.

[0225] Specifically, as shown in Figure 28 、 30As shown in FIG. 31, the sealing member includes a sealing body 340c and a sealing lip 340d, and a plurality of sealing lips 340d extend radially outward from the sealing body 340c and abut against the reduced portion 326. In the cleaning device 10 of the embodiment, the sealing member is arranged on the first housing 310a.

[0226] In an optional embodiment, the number of the sealing lips 340d can be two or more, and the plurality of sealing lips 340d are arranged on the sealing body 340c to enhance the sealing effect and achieve multi-layer sealing.

[0227] In an optional embodiment, as shown in FIG. 32, the sealing lip 340d is arranged on the sealing body 340c in a plurality of rows. Figure 31 When the plurality of sealing lips 340d are arranged, the length of the extension of each sealing lip 340d away from the sealing body 340c gradually decreases from the mounting direction of the first housing 310a. In this way, the first housing 310a can be mounted more smoothly during the mounting process (i.e., the process of abutting the sealing member against the reduced portion 326).

[0228] In an optional embodiment, as shown in FIG. 33, the thickness of the plurality of sealing lips 340d gradually decreases from the mounting direction of the first housing 310a. Figure 31 The sealing lip 340d that is in contact with the reduced portion 326 first is more likely to deform and continue to act on the reduced portion 326, and the sealing lip 340d that is in contact with the reduced portion 326 last is less likely to deform, thereby ensuring sealing when in place, facilitating the mounting of the first housing 310a, making the mounting of the first housing 310a more smooth, and ensuring the sealing effect.

[0229] In an optional embodiment, as shown in FIG. 34, the sealing lip 340d is arranged on the sealing body 340c in an inclined manner, and the inclination direction is toward the dismounting direction of the first housing 310a. Figure 31 In this way, the mounting of the first housing 310a is more smooth, and the mounting of the first housing 310a is facilitated.

[0230] In an optional embodiment, as shown in FIG. 35, the thickness of the sealing lip 340d gradually decreases away from the sealing body 340c. In this way, the strength of the root of the sealing lip 340d is improved, and the flexibility of the end is increased, so that the end can be deformed and sealed better. Figure 31 In an exemplary embodiment, the cross section of each sealing lip 340d is triangular or trapezoidal, which facilitates the mounting of the first housing 310a and ensures the sealing effect.

[0231]

[0232] ​In an optional embodiment, the sealing lip 340d extends outwardly by a length greater than the gap between the first housing 310a and the second inner wall 320c of the second housing 320a, and smaller than the gap between the first housing 310a and the first inner wall 320b of the second housing 320a, i.e. after the first housing 310a is installed in place, the sealing lip 340d can abut and seal with the second inner wall 320c, and when the first housing 310a is not installed in place or is removed, the sealing lip 340d is located in the first inner wall 320b and is not in contact with the first inner wall 320b, forming a gap between the sealing lip 340d and the first inner wall 320b, thereby avoiding additional frictional resistance during installation and removal, making the installation and removal of the first housing 310a smoother. At the same time, if the liquid in the first housing 310a or the liquid between the first housing 310a and the second housing 320, during the removal of the first housing 310a, can flow into the second bin 320 through the above-mentioned gap, preventing the liquid from being taken out with the first housing 310a, affecting the user experience.

[0233] The second suction device 500 described in the above embodiments is a gas suction device, and since the gas suction device also has a certain risk of water ingress, in order to further solve the problem of water ingress of the gas suction device, the second suction passage 321 is designed for gas-liquid separation, such as the above-mentioned baffle structure. In some other embodiments of the present application, the second suction device 500 can also be a liquid suction device, which can allow liquid to pass through, so there is no need to solve the problem of water ingress.

[0234] In some embodiments, referring to Figures 32-34 , the second suction device 500 includes a liquid suction device located in the second suction passage 321; at this time, the second suction passage 321 and the passage of the liquid leakage structure 312 are the same passage, wherein the second suction passage 321 includes a liquid inlet and a liquid outlet, the liquid inlet and the liquid suction end of the liquid suction device are in communication, and the liquid outlet and the liquid outlet end of the liquid suction device are in communication. The liquid suction device is used to drive the sewage in the first bin 310 into the second bin 320. This setting does not need to worry about the problem of water damage to the liquid suction device; in order to make the liquid suction device work better, a filter screen 350 can be further provided in the first bin 310 to separate the sewage sucked into the first bin 310 from the outside, and then only the separated sewage is driven into the second bin 320 by the liquid suction device. At the same time, no matter whether the cleaning device 10 is in an inclined, lying, shaking or upright state, this setting can effectively prevent the liquid in the second bin 320 from flowing back to the first bin 310; it can also ensure that the liquid in the first bin 310 is discharged in time to prevent the first suction device 400 from water ingress.

[0235] In the embodiments of the present application, when the first shell 310a is partially or wholly arranged in the second shell 320, i.e., the first shell 310a is nested in the second shell 320, in order to enable the first shell 310a and the second shell 320 to be stably mounted, when the first shell 310a and the second shell 320 are arranged in interference fit, there is a large frictional force in the process of taking out or mounting the first shell 310a, or the first shell 310a is not convenient for the user to take, thereby causing the user experience to be not friendly when the user disassembles the first shell 310a and the second shell 320. Therefore, the embodiments of the present application propose the following solutions:

[0236] In some embodiments, as Figures 35-41 , the first shell 310a is detachably connected with the second shell 320a, and a handle 313 is mounted on the first shell 310a, so that the user can hold the handle 313 to pull out the first shell 310a from the second shell 320a.

[0237] In an optional implementation, referring to Figure 35 , 36 , the handle 313 is rotationally arranged on the first shell 310a, wherein the handle 313 has a first position (as shown in Figure 35 ) accommodated on the first shell 310a and a second position (as shown in Figure 36 ) rotated to be taken by the user. When the handle 313 is in the first position, the handle 313 can be buckled on the side of the first shell 310a, and the side surface of the handle 313 is flush with the end surface 310m of the first shell 310a, so that the handle 313 does not hinder the installation of the water tank 300 formed by the first shell 310a and the second shell 320a on the main body 100. When the handle 313 is in the second position, the handle 313 is arranged at an angle with the end surface 310m of the first shell 310a to be taken and forced by the user, so that the first shell 310a can be taken out of the second shell 320a.

[0238] In an optional implementation, referring to Figure 37 , when the first shell 310a side is provided with an opening 325 communicating with the first compartment 310, the handle 313 can be rotated from the first position to the second position along the side of the first shell 310a provided with the opening 325, so that the user's hand can hold the handle 313, and the fingers abut the upper end of the first shell 310a, thereby stably taking the first shell 310a and reducing the possibility of the stored objects in the first compartment 310 falling out of the opening 325.

[0239] In an optional implementation, referring to Figure 37, the angle between the handle 313 and the front end surface 310h of the first shell 310a when the handle 313 is in the second position is greater than or equal to 90°. In this way, the user can hold the first shell 310a more stably when taking out the dirt. The end surface 310m of the first shell 310a is divided into a front end surface 310h and a rear end surface 310k by the rotation shaft 313d of the handle 313. The front end surface 310h is the end surface part in the direction of rotation when the handle 313 rotates from the first position to the second position, and vice versa for the rear end surface 310k.

[0240] In an optional embodiment, referring to Figures 38-41 , the first shell 310a and / or the handle 313 is provided with a position reaching prompt device 314, so that when the handle 313 rotates relative to the first shell 310a to the first position and / or the second position, the position reaching prompt device 314 can generate a position reaching prompt to prompt the user that the handle 313 has rotated to a specific position.

[0241] In an optional embodiment, the position reaching prompt device 314 can be provided only in the first position or the second position, or can be provided in both the first position and the second position.

[0242] For example, the user will apply force to the handle 313 during rotation of the handle 313. The position reaching prompt device 314 can be a structure that can generate a changing resistance to the handle 313 during rotation of the handle 313. The resistance of the handle 313 at the first position and the second position is different from that at other positions, so that the user can clearly perceive the difference in resistance during rotation of the handle 313 and identify different positions. In other embodiments, the resistance at the first position and the second position is also different. In this way, by setting different resistances between the handle 313 and the first shell 310a and / or the second shell 320, and then transmitting the resistance to the user, the purpose of reaching the position of the user is achieved.

[0243] It should be noted that the in-position prompting device 314 can be realized by a mechanical structure or by an in-position detection device. Specifically, the in-position prompting device 314 includes an in-position protrusion 314a and an in-position groove 314b matched with the in-position protrusion 314a, and the in-position protrusion 314a and the in-position groove 314b are respectively arranged on the handle 313 and the first shell 310a. The in-position protrusion 314a can be arranged on the first shell 310a, or the in-position groove can be arranged on the first shell 310a. Specifically, when the handle 313 is rotated to the first position or the second position, the handle 313 will change the resistance when passing the in-position protrusion 314a, thereby prompting the user to be in position. The in-position prompting device 314 can also be a magnetic attraction piece, such as a magnetic attraction piece arranged on the handle 313 and the first shell 310a and / or the second shell 320, and the in-position prompting function is formed by the connection between the two magnetic attraction pieces. Further, the magnetic attraction pieces can be arranged at the first position and / or the second position.

[0244] In an optional embodiment, the handle 313 is arranged on the first shell 310a by damping rotation, wherein the rotation resistance of the handle 313 when located at the first position and / or the second position is greater than the rotation resistance when the handle 313 is located between the first position and the second position. The damping resistance can make the user feel in position, and the damping resistance between the handle 313 and the first shell 310a when the handle 313 is located at the second position can make the user more stable when grabbing the first shell 310a through the handle 313 when dumping garbage.

[0245] It should be noted that the rotation resistance can be achieved by designing a damping rubber ring between the handle 313 and the first shell 310a to form a damping feeling, or a rubber ring is sleeved on the rotating shaft 313d, and then the handle 313 or the first shell 310a is assembled, so that the handle 313 has a damping feeling during rotation. The present application is not limited thereto.

[0246] In an optional embodiment, as shown in Figures 38-40 , the first shell 310a has a limiting portion 314c for preventing the handle 313 from continuing to rotate forward. The handle 313 includes a handle 313e, a rotating shaft 313d, and an abutting portion 313f, and the opposite sides of the rotating shaft 313d are respectively provided with the handle 313e and the abutting portion 313f. The handle 313e is used to provide user holding, and the limiting portion 314c is arranged in front of the handle 313e (not shown) and / or arranged behind the abutting portion 313f (as shown in Figure 38 、 40 ).

[0247] The limiting part 314c can be arranged to enable the handle 313 to stay at the second position, thereby facilitating the application of force to the handle 313 to lift the first shell 310a from the second shell 320a, and enabling the user to be more stable during the cleaning of the garbage in the first shell 310a.

[0248] In an optional embodiment, as shown in Figure 35 、 36 The rotating shaft 313d of the handle 313 is provided with an abutting part 313f, and the second shell 320a includes a first abutting surface 320d. During the rotation of the handle 313 from the first position to the second position, the abutting part 313f is rotated towards the first abutting surface 320d and finally abuts against the first abutting surface 320d. When the handle 313 is continuously rotated, the abutting part 313f of the handle 313 acts on the first abutting surface 320d, and the contact point between the abutting part 313f and the first abutting surface 320d serves as a fulcrum to apply an upward pushing force to the rotating shaft 313d of the handle 313, thereby pushing the rotating shaft 313d of the handle 313 away from the first abutting surface 320d and finally driving the first shell 310a to be separated from the second shell 320. In some cases, the first shell 310a and the second shell 320a are nested, and a sealing member is arranged between the first shell 310a and the second shell 320a. Due to the sealing effect, the resistance is the largest when the first shell 310a is just taken out. According to the principle of the force multiplier, the large force arm of the handle 313 drives the abutting part 313f to pry the first shell 310a in the position state by a small distance, thereby overcoming the relatively large resistance when the first shell 310a is just taken out, and making the taking-out process of the first shell 310a more smooth.

[0249] In an optional embodiment, as shown in Figure 35 、 36As shown, the second shell 320a comprises a second abutting surface 320e. After the first shell 310a is installed into the second shell 320a, in the process of rotating the handle 313 from the second position to the first position, the handle 313 drives the abutting portion 313f to rotate towards the second abutting surface 320e and contact the second abutting surface 320e, and then the handle 313 continues to rotate, the abutting portion 313f and the second abutting surface 320e interact, the handle 313 applies a downward pressure to the rotation shaft 313d of the handle 313 with the contact point between the abutting portion 313f and the second abutting surface 320e as the fulcrum, and then presses the first shell 310a downward into the installation position of the second shell 320a. In the whole process, that is, by the principle of lever, the long arm of the handle 313 drives the abutting portion 313f to press the first shell 310a that has not been installed into the second shell 320a into the second shell 320a. At the same time, in some cases, there is a sealing element between the first shell 310a and the second shell 320, and the cooperation of the abutting portion 313f of the handle 313 and the second abutting surface 320e can enable the first shell 310a to accurately install the second shell 320a into position, so as to establish a better seal between the first shell 310a and the second shell 320a.

[0250] In an optional embodiment, the second shell 320a is provided with a receiving groove 315 for accommodating the abutting portion 313f of the handle 313, the groove bottom wall of the receiving groove 315 forms the first abutting surface 320d, and the groove top wall of the receiving groove 315 forms the second abutting surface 320e, wherein the groove bottom wall and the groove top wall can be oppositely arranged or arranged in a substantially opposite state.

[0251] In an optional embodiment, referring to Figure 36 , the abutting portion 313f comprises an abutting surface 3133f and first and second surfaces 3131f and 3132f located on both sides of the abutting surface 3133f, and the distance from the abutting surface 3133f to the center of the rotation shaft of the handle 313e is greater than the distance from the first surface 3131f to the center of the rotation shaft of the handle 313e. When the handle 313 is in the first position, the first surface 3131f faces the first abutting surface 320d; when the handle 313 is in the second position, the abutting surface 3133f abuts against the first abutting surface 320d. Such an arrangement enables the surface of the abutting portion 313f that faces the first abutting surface 320d to transition from the first surface 3131f to the abutting surface 3133f in the process of rotating the handle 313 from the first position to the second position, at which time the gap between the abutting portion 313f and the first abutting surface 320d gradually decreases until the abutting surface 3133f contacts the first abutting surface 320d, and with the rotation of the handle 313, the abutting surface 3133f further abuts against the first abutting surface 320d to separate the first shell 310a from the second shell 320.

[0252] In an optional embodiment, when the handle 313 is in the second position, the second surface 3132f has a gap with the second abutting surface 320e; when the handle 313 is in the first position, the second surface 3132f abuts against the second abutting surface 320e. Such an arrangement can make the gap between the second abutting surface 320e and the abutting portion 313f gradually smaller when the handle 313 rotates from the second position to the first position, i.e., the second surface 3132f gradually approaches the second abutting surface 320e during the rotation of the handle 313 until the second surface 3132f contacts the second abutting surface 320e; further, as the handle 313 continues to rotate, the second surface 3132f can abut against the second abutting surface 320e so that the second abutting surface 3133f generates a downward force on the second surface 3132f, thereby pressing the first shell 310a into the second shell 320.

[0253] In an optional embodiment, the abutting portion 313f is in the shape of a cam or a long arm; the protruding surface of the cam corresponds to the abutting surface 3133f; the surface at one end of the long arm corresponds to the abutting surface 3133f.

[0254] In an optional embodiment, the first shell 310a and the second shell 320a are in interference fit; the interference fit can make the first shell 310a and the second shell 320 more stable during installation; the interference fit can be direct interference fit between the first shell 310a and the second shell 320, or indirect interference fit between the first shell 310a and the second shell 320 through other components, such as a sealing member, an elastic member, etc. In addition, since the interference fit can cause large frictional force during the installation and removal of the first shell 310a and the second shell 320, it is not conducive to user experience, or can cause the problem that the first shell 310a is not installed in place.

[0255] Therefore, in order to facilitate the first shell 310a from the second shell 320, the rotating connection of the handle 313 is provided with the abutting portion 313f, the abutting portion 313f includes the abutting surface 3133f, the distance from the abutting surface 3133f to the center of the rotating shaft of the handle 313e is greater than the travel of the first shell 310a and the second shell 320a in the direction of the interference fit. The travel of the interference fit here refers to the displacement between the starting point and the position of removing the interference fit in the process of taking the first shell 310a from the second shell 320. The inner diameter of the second shell 320 is different, and the interference fit is formed at the position with small inner diameter, and the interference fit is removed at the position with large inner diameter. The distance from the abutting surface 3133f to the center of the rotating shaft is set in this way, so that in the process of taking the first shell 310a from the second shell 320, the handle 313 is rotated upward, and the abutting surface 3133f of the abutting portion 313f gradually abuts the second shell 320, thereby forming the displacement between the first shell 310a and the second shell 320. The distance of the displacement is also the distance that the handle 313 can assist the first shell 310a to take out, and this part of the distance only needs to be greater than the distance of the interference fit that the first shell 310a and the second shell 320 need to pass through in the process of taking out, then the handle 313 can use its leverage to help the user overcome the problem of difficult to take out caused by the interference fit distance, so as to improve the user experience.

[0256] The first shell 310a and the second shell 320 are interference fit;

[0257] When the handle 313 rotates from the first position to the second position, the displacement of the first shell 310a in the direction of taking out is greater than the travel of the first shell 310a from the second shell 320 in the direction of the interference fit; and / or,

[0258] When the handle 313 is in the first state, the abutting portion 313f is tangent to the second abutting surface 320e.

[0259] In an optional embodiment, a sealing member is arranged between the first shell 310a and the second shell 320, which is used to isolate the first chamber 310 and the second chamber 320, or to form the suction channel of the second suction device 500. Because the presence of the sealing member will cause greater friction when the first shell 310a is taken out or installed from the second shell 320, the leverage of the handle 313 described above can be used to save the user's effort and improve the user experience.

[0260] In an optional embodiment, a necking portion 326 is arranged between the first shell 310a and the second shell 320, mainly to reduce the gap between the first shell 310a and the second shell 320, so that the first shell 310a and the second shell 320 can be stably matched. Meanwhile, the necking portion 326 can also cooperate with the sealing member, which can make the first shell 310a and the second shell 320 more stable and improve the sealing capacity.

[0261] In order to prevent the user from accidentally spilling the dirt inside the first shell 310a during the process of taking out the first shell 310a, the following design is proposed,

[0262] As shown in Figure 42 , for the embodiment in which the first shell 310a is nested in the second shell 320a, in order to facilitate the first shell 310a to be taken out of the second shell 320a, the outer wall of the second shell 320a can be provided with a handhold 327, and the side wall 310c of the first shell 310a has an opening 325, which is arranged towards the handhold 327. The handhold 327 can be used by the user to hold the water tank 300. The opening 325 is arranged towards the handhold 327, so as to facilitate the user to hold the handhold 327 of the second shell 320a with one hand (for example, the right hand) and hold the first shell 310a with the other hand (for example, the left hand) after the sewage tank is taken out, and then take out the first shell 310a from the second shell 320a in a substantially horizontal direction, at this time, the opening of the first tank 310 is substantially upward, and the dirt in the first tank 310 is shielded by the non-opening side wall 310c of the first shell 310a, which can effectively prevent the dirt in the first tank 310 from falling. Figure 42 Figure 42

[0263] In the embodiment of the present application, the dirt generated after the cleaning device 10 cleans the surface to be cleaned is a solid-liquid mixture, and it is not easy for the user to handle the solid-liquid mixture. If the solid-liquid mixture is poured into the sewer, there is a risk of blocking the sewer. If the solid-liquid mixture is poured into the garbage can, there is a risk of the garbage bag being damaged and leaking. Therefore, the embodiment of the present application proposes the following solutions to the above specific technical problems:

[0264] In an optional embodiment, the cleaning device 10 further comprises a dirt suction pipe 112, and the outlet 112c of the dirt suction pipe is in communication with the first tank 310. When the first shell 310a and the second shell 320 are independent of each other as shown in Figure 4 5 , the outlet 112c of the dirt suction pipe is in direct communication with the first tank 310. As shown in Figures 6-10 ​​​,44, when the first shell 310a is at least partially nested in the second shell 320, the dirt suction pipe 112 includes a dirt suction pipe 112a and a dirt inlet pipe 112b, the dirt suction pipe 112a is arranged outside the main body 100, i.e. the first bin 310 and the second bin 320, and the dirt inlet pipe 112b is arranged inside the water tank, the water outlet of the dirt inlet pipe 112b, i.e. the outlet 112c of the dirt suction pipe, is used to drive the external dirt into the first bin 310. The first suction device 400 can sequentially suck the gas through the first suction passage 311, the first bin 310 and the first suction passage 311 to form a negative pressure, so as to suck the external dirt into the first bin 310.

[0265] In some embodiments, as shown in Figure 18 、 24 ,43, the first bin 310 is provided with a filter screen 350, which is arranged between the liquid leakage structure 312 of the first bin 310 and the second bin 320 and the outlet 112c of the dirt suction pipe; wherein the first bin 310 is located at one side of the outlet end to form a solid waste chamber 316 for containing solid waste, so that the first suction device 400 can suck the external dirt into the first bin 310 through the dirt suction pipe 112, and then the first bin 310 can accumulate the solid waste in the dirt in the solid waste chamber 316, and the liquid can flow into the second bin 320 through the liquid leakage structure 312 or be sucked into the second bin 320 by the second suction device 500, so as to realize solid-liquid separation.

[0266] The filter screen 350 can separate the dirt generated during cleaning into solid waste stored in the first bin 310 and liquid stored in the second bin 320, which can facilitate the user to separate and process different types of dirt, so as to reduce the probability of occurrence of bad user experience such as blockage of the sewer or spilling of liquid on the ground. At this time, driving the separated liquid into the second bin 320 by the second suction device 500 (including a gas suction device and a liquid suction device) can improve the dryness of the space in the first bin 310, reduce the probability of water or water vapor in the first bin 310 entering the first suction device 400, and also improve the dryness of the solid-liquid waste, so as to reduce the bad experience of the user when handling the solid waste due to dripping. In an optional embodiment, as shown in Figure 18 、 24 , the filter screen 350 is located at the bottom of the first bin 310, i.e. above the bottom wall of the first shell 310a, and the liquid leakage structure is arranged below the filter screen 350, so that the dirt can also be subjected to solid-liquid separation under the action of gravity, the solid waste chamber 316 is formed above the filter screen 350 for accumulating solid waste, and the liquid leakage structure 312 is formed below the filter screen 350 to enable the liquid filtered from the dirt to flow to the second bin 320.

[0267] In some embodiments, such as Figure 18 , 24 As shown in Figure 43, the filter screen 350 is rotatably disposed in the first compartment 310 so that when cleaning the filter screen 350 or removing solid waste from the solid waste chamber 316, the filter screen 350 can rotate from the inside to the outside of the first compartment 310. When emptying the waste, after tilting the first housing 310a to a certain angle, the filter screen 350 will rotate due to gravity, and the waste above the filter screen 350 will be carried away from the solid waste chamber, preventing solid waste from adhering to the solid waste chamber 316. At this time, the filter screen 350 and the solid waste adhering to the filter screen 350 can be directly rinsed and removed. This arrangement facilitates the processing of waste in the solid waste chamber.

[0268] In some embodiments, such as 24, 43, and 45, the filter 350 is rotatably mounted in the first chamber 310 via a rotating joint 351.

[0269] For example, the filter 350 is rotatably mounted in the first chamber 310 via a rotating joint 351, wherein the axis of rotation of the rotating joint 351 is arranged in a generally horizontal direction; or, the axis of rotation of the rotating joint 351 is arranged in a vertical direction. The above-mentioned generally horizontal and generally vertical refer to the fact that when the main body 100 of the cleaning device 10 is in a vertical state, the axis of rotation of the rotating joint 351 is within a range of no more than 10° between horizontal and vertical.

[0270] In one optional embodiment, the first compartment 310 has an opening 325 on one side, and a rotating mounting part 353 is provided below the opening 325 of the first compartment 310. A rotating part 351 is mounted on the rotating mounting part 353, and the filter screen 350 can be flipped outward around the lower side at the opening 325 of the first compartment 310 to open the first compartment 310. Figure 43 As shown.

[0271] In one alternative implementation, such as Figure 24 As shown, the first compartment 310 has an open opening 325 on one side. The solid waste chamber 316 has a rotating mounting part 353 on one side of the open opening 325. The rotating part 351 is mounted on the rotating mounting part 353. The filter screen 350 can be flipped around the left and right sides at the open opening 325 of the first compartment 310 to open the first compartment 310.

[0272] In one alternative implementation, such as Figure 24, the filter screen 350 comprises a first filter screen 350a and a second filter screen 350b capable of rotating towards each other, wherein the first bin 310 is open at the side 325, the first filter screen 350a is rotatably installed at the left side of the solid waste chamber 316, and the second filter screen 350b is rotatably installed at the right side of the solid waste chamber 316, and the first filter screen 350a and the second filter screen 350b are respectively flipped around the left and right sides of the opening 325 at the side opening 325 of the first bin 310 to open the first bin 310.

[0273] In an optional embodiment, as Figure 24 , the filter screen 350 has a filter screen bottom plate 350c and a filter screen side plate 350d connected to the edge of the filter screen bottom plate 350c, wherein the filter holes 352 of the filter screen 350 are arranged on the filter screen bottom plate 350c and / or the filter screen side plate 350d. The filter screen side plate 350d can block the garbage on the filter screen bottom plate 350c after the first bin 310 is removed, preventing the garbage on the filter screen bottom plate 350c from leaking out of the edge, and the filter screen side plate 350d also increases the effective area of the filter screen 350, making the solid-liquid separation efficiency in the first bin 310 higher, so that the sewage in the first bin 310 can enter the second bin 320 faster through the liquid leakage structure 312, which is conducive to reducing the risk of liquid entering the first suction device 400.

[0274] Optionally, the height of the filter screen side plate 350d is adapted to the height of the first bin 310 to seal the side of the first bin 310, further preventing the garbage in the first bin 310 from falling out.

[0275] In an optional embodiment, the filter screen 350 is detachably connected to the first bin 310, and when dumping garbage, the filter screen 350 can be removed together with the garbage, and the filter screen 350 can be separately dumped and cleaned, facilitating replacement or cleaning of the filter screen 350.

[0276] Optionally, the filter screen 350 can be provided with a filter screen taking part for taking out the filter screen 350 from the first bin 310, facilitating taking and placing of the filter screen 350.

[0277] In an optional embodiment, the filter screen 350 is located at the lower end of the first bin 310, capable of separating the solid-liquid in the first bin 310 at the bottom of the first bin 310, maximizing the use of the volume of the first bin 310, and maximizing the solid waste chamber 316 in the first bin 310.

[0278] In an optional embodiment, as Figure 46As shown, the filter screen 350 has a three-dimensional structure, such as a column shape; and the filter screen 350 is arranged around the liquid leakage structure 312, and the filter screen 350 is arranged along the height direction, thereby increasing the area of the filter screen 350 in the height direction, and the filter screen 350 is not easily blocked during the accumulation of solid waste, and the solid waste in the solid waste chamber 316 can ensure a high filtering efficiency at any height.

[0279] In an optional embodiment, the filter screen 350 is a disposable box body which can be placed in the first bin 310; the box body is shaped to fit the first bin 310; the box body has a bottom wall and a side wall, the bottom wall has filter holes 352; the bottom wall of the box body is adapted to the bottom wall of the first bin 310; the side wall of the box body is adapted to the inner side wall of the first housing 310a and / or the second housing 320a; the side wall of the box body can be used to prevent garbage from falling when the filter screen 350 is removed; the side wall of the box body can also be provided with filter holes 352; the box body can also be designed in the above-mentioned manner. By setting the filter screen as a disposable filter screen, the difficulty of the user in handling garbage can be further reduced.

[0280] The first suction device 400 is usually a device capable of generating negative pressure such as a fan in the cleaning device 10, and the first suction device 400 is connected to the first bin 310 through the first suction passage 311, and is used to provide power for sucking the dirt generated during the operation of the cleaning device 10 back to the first bin 310. However, the dirt usually contains water or water vapor, which can easily enter the first suction device 400 through the first suction passage 311, thereby causing damage to the first suction device 400 or liquid leakage. Therefore, the embodiments of the present application are improved as follows:

[0281] In an optional embodiment, as shown in Figures 47-49 The first housing 310a can be provided with an air inlet 317, and the air inlet 317 is used to connect the first suction device 400 to the first bin 310, and the passage of the air inlet 317 constitutes part of the first suction passage 311. The first suction device 400 provides suction power for the first bin 310 through the air inlet 317, so that the external dirt can be sucked into the first bin 310.

[0282] Exemplarily, as shown in Figure 47 , 48As shown, the first shell 310a includes a top wall 310b and a side wall 310c, wherein the air inlet 317 is arranged on the top wall 310b, and the edge of the air inlet 317 is spaced apart from the side wall 310c. During the process of the first suction device 400 sucking the first cartridge 310 through the air inlet 317, water on the side wall 310c can be sucked upward along the side wall 310c by the suction force of the first suction device 400 and then enter the first suction device 400. When the water on the side wall 310c moves upward along the side wall 310c, it can be blocked by the top wall 310b between the edge of the air inlet 317 and the side wall 310c to hinder the water from directly entering the air inlet 317 upward along the side wall 310c, thereby reducing the probability of liquid directly entering the first suction device 400 from the air inlet 317.

[0283] In an optional embodiment, the first shell 310a is provided with a water blocking structure 318 on the top wall 310b, and the water blocking structure 318 is used to block liquid from entering the air inlet 317.

[0284] Exemplarily, as shown in FIG. 6, the water blocking structure 318 can include a first water blocking part 318a arranged on the rear side of the air inlet 317 to block liquid in the first cartridge 310 from oscillating to the air inlet 317 from the rear side. When the main body 100 is tilted or laid down, liquid flows to the rear side, resulting in a higher base water level. When the liquid further oscillates upward, it can be blocked by the first water blocking part 318a arranged on the rear side of the air inlet 317. Figure 46 , 47 Optionally, the first water blocking part 318a is arranged in the left-right direction.

[0285] In an optional embodiment, as shown in FIG. 7, the water blocking structure 318 can include a second water blocking part 318b arranged on the front side of the air inlet 317 to block liquid in the first cartridge 310 from oscillating to the air inlet 317 from the front side. When the main body 100 is tilted or laid down, liquid flows to the front side, resulting in a lower base water level. When the liquid further oscillates upward, it can be blocked by the second water blocking part 318b arranged on the front side of the air inlet 317. Figure 47The water blocking structure 318 includes a second water blocking portion 318b located between the air inlet 317 and the sidewall 310c of the first housing 310a, and has a spacing between the second water blocking portion 318b and the sidewall 310c of the first housing 310a to block the wall hanging liquid on the top wall 310b and the sidewall 310c. For example, the second water blocking portion 318b is a wall surface extending downward from the top wall 310b, which can be a plane or an arc surface, and is arranged on the periphery of the air inlet 317. During the process of the air inlet 317 sucking the first chamber 310, water droplets or water film can be sucked upward along the sidewall 310c due to the surface tension of the water, and the second water blocking portion 318b can prevent the water droplets or water film from flowing along the top wall 310b into the air inlet 317. In an alternative embodiment, the outlet 112c of the suction pipe communicates with the first chamber 310, and the water blocking structure 318 includes a third water blocking portion 318c located between the air inlet 317 and the outlet 112c of the suction pipe to block the liquid of the outlet 112c of the suction pipe from being directly sucked into the air inlet 317. For example, as shown in Figure 50 , the third water blocking portion 318c is an annular wall arranged on the top of the first chamber 310, and the lower edge of the third water blocking portion 318c is located below the outlet 112c of the suction pipe.

[0286] It should be noted that the first water blocking portion 318a, the second water blocking portion 318b and the third water blocking portion 318c can be connected to form an integral body, and the integral body can be arranged around at least part of the air inlet 317. For example, the integral body is in a cylindrical shape.

[0287] In some embodiments, as shown in Figure 48 , the water blocking portion 318 further includes a fourth water blocking portion 318d arranged between the air inlet 317 and the water blocking portion 318c to prevent the wall hanging liquid of the water blocking portion 318c from entering the air inlet 317. The fourth water blocking portion 318d can form an integral body with the first water blocking portion 318a and the second water blocking portion 318b, and the integral body can be arranged around at least part of the air inlet 317. For example, the integral body is in a cylindrical shape.

[0288] The purpose of the water blocking portion 318 is mainly to block the liquid from the first chamber 310 into the air inlet 317, and the structure form is not limited in the present application as long as it can block the liquid from the first chamber 310 into the air inlet 317. In some embodiments, only one or two of the first water blocking portion 318a, the second water blocking portion 318b, the third water blocking portion 318c and the fourth water blocking portion 318d can be arranged.

[0289] In an alternative embodiment, as shown in Figure 46 , 47As shown, the air inlet 317 is located on the front side of the first tank 310 to reduce the probability of liquid flowing into the air inlet 317 from the first tank 310 when the main body 100 is in an inclined or lying state. When the main body 100 is lying, the air inlet 317 located on the front side can be located above the first tank 310 in the lying state and is far away from the liquid level in the state, preventing liquid from flowing into the air inlet 317 in the lying state of the first tank 310.

[0290] In an optional embodiment, the air inlet 317 is two, and the two air inlets 317 are respectively located on the left and right sides of the outlet 112c of the suction pipe, and are arranged in sequence to make the space in the first tank 310 more compact, and the suction pipe 112 and the air inlet 317 can be arranged on the same side of the first tank 310 (i.e., both located on the front side of the first tank 310). When the main body 100 is lying, the outlet 112c of the suction pipe and the air inlet 317 can be located on the upper side of the first tank 310, and are far away from the liquid level in the first tank 310 at this time, preventing the liquid in the first tank 310 from flowing back into the air inlet 317 or along the outlet 112c of the suction pipe back to the surface to be cleaned. Further, a third water blocking part 318c can be arranged between the suction pipe 112 and the air inlet 317 to prevent liquid from being directly sucked into the air inlet 317 from the outlet 112c of the suction pipe.

[0291] In an optional embodiment, the outlet 112c of the suction pipe is located on the front side of the first tank 310, and when the main body 100 is in an inclined or lying state, the outlet 112c of the suction pipe is located on the upper side of the first tank 310 and is far away from the liquid level in the first tank 310 at this time, which can prevent the liquid in the first tank 310 from flowing back to the ground along the outlet 112c of the suction pipe.

[0292] In an optional embodiment, the outlet 112c of the suction pipe is located above the lower edge of the third water blocking part 318c, which can change the direction of the fluid (including water flow and air flow) by 180 degrees, from upward to downward flow, and then after being sucked by the air inlet 317 above, from downward to upward flow. Through two changes of direction, the liquid mixed in the air flow is thrown out, thereby assisting the liquid-air separation in the first tank 310.

[0293] It can be understood that the third water blocking part 318c can be a circular ring, a rectangular frame or a polygonal frame, and is arranged around the outlet 112c of the suction pipe. The third water blocking part 318c can also be a baffle. In some embodiments, the third water blocking part 318c can be at least two, and the number of the first water blocking part 318a and the second water blocking part 318b is not limited.

[0294] In an optional embodiment, as shown in FIG. 6, the first water blocking part 318a and the second water blocking part 318b are arranged on the left and right sides of the air inlet 317, respectively. Figure 50The distance between the left and right sides of the third water retaining part 318c and the suction pipe 112 is smaller than the distance between the back side of the third water retaining part 318c and the suction pipe 112, that is, the liquid and gas flow out of the suction pipe 112 will flow downward through the gap between the third water retaining part 318c and the suction pipe 112. The gap between the back side of the third water retaining part 318c and the suction pipe 112 is larger, which is conducive to reducing the speed of the liquid and gas flow out of the gap, thereby preventing the water flow and liquid out of the gap from causing a large impact on the liquid leakage structure 312. Because a larger impact will cause an impact on the liquid accumulated at the liquid leakage structure 312, the liquid accumulated at the liquid leakage structure 312 and not yet entering the second bin 320 may be dispersed under a large impact, especially when most of the liquid entering from the suction pipe 112 is gas, which will affect the liquid to converge to the liquid leakage structure 312, thereby affecting the normal operation of the liquid leakage structure 312. The gap between the left and right sides of the third water retaining part 318c and the suction pipe 112 is smaller, which is conducive to increasing the speed of the liquid and gas flow out of the gap, thereby improving the separation effect of the liquid and gas flow out of the gap.

[0295] In some embodiments, the front side of the outlet 112c of the suction pipe is higher than the back side (as shown in FIG. 12B), which can cause the dirt flowing out of the suction pipe 112 to flow to the back side. Because the suction pipe 112 is arranged at the front side, the dirt flowing out of the outlet 112c of the suction pipe can enter the larger space at the back side of the suction pipe 112, preventing the outlet 112c of the suction pipe from being blocked. Figure 49

[0296] In some embodiments, as shown in FIG. 12A, the cleaning device 10 is provided with a content detection assembly 360, and the control device 600 is connected with the content detection assembly 360. The content detection assembly 360 is arranged in the first bin 310 and / or the second bin 320, and is used to detect the content information of the dirt in the first bin 310 and / or the second bin 320, so that the control device 600 can adjust the operating parameters of the first suction device 400 and / or the second suction device 500 according to the content information of the dirt detected by the content detection assembly 360. Figure 7

[0297] For example, the first bin 310 can be provided with a filter screen 352 to form a solid-liquid separation bin. At this time, the content information can indicate the capacity of solid waste.

[0298] For example, the first detection assembly 361 in the first bin 310 is arranged above the first bin 310.

[0299] ​​For example, the first detection assembly 361 in the first bin 310 is arranged on the rear side above the first bin 310. In this way, if the first detection assembly 361 is triggered by liquid when the cleaning device is in the lying state, it indicates that the first suction device 400 has a risk of liquid ingress.

[0300] For example, the first detection assembly 361 in the first bin 310 is arranged below the air inlet 317. In this way, the first detection assembly 361 can be triggered before the contents in the first bin 310 block the air inlet 317.

[0301] Further, a prompting device (not shown) can also be included and electrically connected to the contents detection assembly 360. When the amount of dirt in the first bin 310 and / or the second bin 320 reaches a preset value or is triggered, the prompting device can notify the user to replace or clean the first bin 310 and / or the second bin 320, so as to reduce the possibility of safety hazards caused by liquid backflow in the first bin 310 and the second bin 320.

[0302] For example, the control device 600 is connected to the first detection assembly 361, the first suction device 400 and / or the second suction device 500. When the amount of dirt in the first bin 310 reaches a preset value or is triggered, the control device 600 can adjust the operating parameters of the first suction device 400, so as to reduce or close the suction force of the first suction device 400, thereby reducing the possibility of liquid in the first bin 310 entering the first suction device 400.

[0303] Meanwhile, when the amount of dirt in the first bin 310 is large (for example, there is a large amount of solid waste in the first bin 310), it will to some extent cause the liquid in the first bin 310 to be difficult to enter the second bin 320. Therefore, in this scenario, the control device 600 can adjust the operating parameters of the second suction device 500 to increase the suction force of the second suction device 500, so that the second suction device 500 provides a larger suction force to more fully suck the liquid in the first bin 310 to the second bin 320.

[0304] It should be noted that the detection of the amount of dirt in the first bin 310 by the first detection assembly 361 includes detection of solid objects, viscous objects or liquid in the first bin 310, and the specific detection method includes but is not limited to detection of the height of the dirt, detection of the weight of the dirt, or even direct acquisition of the amount of dirt by visual means. The present application is not limited in this regard.

[0305] In an embodiment, the cleaning device comprises a second detection assembly 362 which detects the content information of the second tank. For example, when the amount of dirt in the second tank 320 reaches a preset amount, the control device 600 can adjust the operating parameters of the second suction device 500 so that the suction force of the second suction device 500 is reduced or turned off, thereby reducing the possibility of liquid in the second tank 320 310 entering the second suction device 500; in this case, in order to reduce the probability of water entering the first suction device 400, when the amount of dirt in the second tank 320 reaches the preset amount, the control device 600 can also reduce or turn off the suction force of the first suction device 400, thereby avoiding continuous increase of liquid in the second tank 320.

[0306] For example, the operating parameters of the first suction device 400 and the second suction device 500 include at least one of the following: operating power, operating time, operating voltage, operating duty cycle current, so that the control device 600 can control the working time and suction force of the first suction device 400 and the second suction device 500 through the operating parameters, so that the external liquid can enter the first tank 310, the liquid in the first tank 310 can enter the second tank 320, and under the control of the control device 600, the operating parameters of the first suction device 400 and the second suction device 500 can be flexibly adjusted according to the current state of the cleaning device 10 or the amount of dirt in the first tank 310 and / or the second tank 320. In particular, when the amount of liquid dirt is large, the suction device can be turned off or the suction force of the suction device can be reduced (the greater the suction force, the greater the required operating power, and the greater the operating power, the greater the risk of liquid entering the suction device), thereby timely protecting the first suction device 400 and the second suction device 500.

[0307] From another aspect, since the operating parameters of the second suction device 500 can be flexibly adjusted according to the amount of dirt in the first tank 310, when the amount of dirt in the first tank 310 is small, the operating power of the second suction device 500 can be small, and when the amount of dirt in the first tank 310 is large, the operating power of the second suction device 500 can be increased. By matching the amount of dirt in the first tank 310 with the operating parameters of the second suction device 500, the operating parameters of the second suction device 500 are dynamically adjusted, thereby avoiding the problem that the second suction device 500 always operates at a large power and the operating noise is always large, reducing the influence of working noise on user experience, and effectively improving user experience.

[0308] In some embodiments, the height of the rear side of the outlet 112c of the suction pipe is higher than the height of the front side of the outlet 112c, and when the main body 100 is tilted or laid down, the rear side of the outlet 112c is higher than the front side, which can form a barrier from the rear side to the front side at the outlet, effectively reducing the risk of backflow of the liquid in the first bin 310 from the front side of the outlet of the suction pipe 112 close to the liquid level when the main body 100 is in a tilted or laid-down state.

[0309] It can be understood that the outlet 112c of the suction pipe is arranged to be inclined, which can change the direction of the gas or liquid flowing out of the outlet 112c of the suction pipe, preventing the gas or liquid from directly impacting the top plate of the first bin 310.

[0310] In the embodiments of the present application, when the first shell 310a is nested in the second shell 320, the first bin 310 and the second bin 320 need to be relatively independent, so as to ensure that the suction force of the gas suction device acts on the liquid leakage structure as much as possible. Therefore, it is necessary to reduce the existence of gaps between the first shell 310a and the second shell 320 as much as possible. Since the suction pipe 112 for recycling the dirt generated by the cleaning device is connected to the first bin 310 after passing through the second shell 320, and in order to facilitate the disposal of the garbage in the first bin 310, the first shell 310a needs to be detachably arranged. Therefore, a gap is formed between the suction pipe 112 and the first shell 310a. In order to reduce the influence of this gap, the embodiments of the present application propose the following solutions:

[0311] In an optional embodiment, as shown in Figures 44-53 the suction pipe 112 further includes a dirt inlet pipe 112b arranged in the second shell 320a and a dirt suction pipe 112a connected to the dirt inlet pipe 112b, the dirt suction pipe 112a being used to suck dirt and sewage on the ground into the dirt inlet pipe 112b. The dirt inlet pipe 112b is in communication with the first bin 310, and a sealing member is arranged at the connection between the dirt inlet pipe 112b and the first shell 310a, which is used to fill the gap between the first shell 310a and the dirt inlet pipe 112b, so as to ensure that the suction force of the second suction device 500 can be concentrated in the liquid leakage structure 312.

[0312] In an optional embodiment, a garbage leak-proof pipe 319 is provided inside the first housing 310a, and a sewage inlet pipe 112b passes through the garbage leak-proof pipe 319. After the first housing 310a is removed, the garbage leak-proof pipe 319 can prevent garbage in the first compartment 310 from falling out through the opening communicating with the sewage inlet pipe 112b. Furthermore, a sixth sealing member 930 can be provided between the garbage leak-proof pipe 319 and the sewage inlet pipe 112b to isolate the sewage inlet pipe 112b and the second compartment 320. The sixth sealing member 930 can be provided on the top or the inner wall of the garbage leak-proof pipe 319, which can reduce the friction between the sealing ring between the sewage inlet pipe 112b and the garbage leak-proof pipe 319 during the removal and placement of the first housing 310a, making the removal and placement of the first housing 310a smoother. The sixth seal 930 can also be located at the bottom of the garbage leak-proof pipe 319, so that the sixth seal 930 can be inserted from the opening of the garbage leak-proof pipe 319 at the bottom of the first housing 310a, which facilitates the assembly of the sixth seal 930.

[0313] In one alternative implementation, such as Figure 52 As shown, a raised edge 319a is provided along the circumference of the inner wall of the garbage leak-proof pipe 319. The end face of the sewage inlet pipe 112b abuts against the raised edge 319a. A sealing element is provided between the end face of the sewage inlet pipe 112b and the raised edge 319a. When the sewage inlet pipe 112b is inserted into the garbage leak-proof pipe 319 and in place, both will apply axial pressure to the sealing ring. During the insertion and removal of both, the sealing ring does not contact the other component, eliminating the frictional resistance caused by the sealing ring during installation and removal, making the placement and removal of the first housing 310a smoother. At the same time, since the first housing 310a is installed into the second housing 320 with an interference fit, the relative position between the first housing 310a and the second housing 320 can be stabilized, thus ensuring the sealing performance of the sealing ring at this point.

[0314] In an optional embodiment, the first housing 310a is provided with a sewage inlet pipe through hole 310n, wherein the sewage inlet pipe 112b passes through the sewage inlet pipe through hole 310n, and the sealing ring is disposed on the outside of the sewage inlet pipe 112b or on the inner wall of the sewage inlet pipe through hole 310n. After the sewage inlet pipe 112b is inserted into the sewage inlet pipe through hole 310n, the sewage inlet pipe 112b and the sewage inlet pipe through hole 310n are mutually sealed by their circumferential surfaces, which reduces the possibility that the sealing effect will be affected when the end face is used for sealing due to the sewage inlet pipe 112b not being inserted into the correct position or the sealing ring not being installed in the correct position.

[0315] In the present application, the first bin 310 and the second bin 320 are used to hold the dirt generated during the cleaning process of the cleaning device 10, but the excessive capacity of the dirt will directly affect the normal operation of the cleaning device 10, and even cause damage to the cleaning device 10, such as sewage entering the first suction device 400 or the second suction device 500, etc., resulting in damage to the cleaning device 10; in order to reduce the probability of such abnormality, the present application proposes the following solutions:

[0316] In an optional embodiment, as shown in Figure 7 、 9 57, 58, the cleaning device 10 further comprises a containing object detection assembly 360, which comprises a first detection assembly 361 and a second detection assembly 362, respectively used to detect the containing object information in the first bin 310 and the containing object information in the second bin 320, so as to realize the detection of the containing objects in the first bin 310 and the second bin 320, and simultaneously detect the first bin 310 and the second bin 320. The containing object information can include solid waste capacity information, liquid level information, water information, etc.

[0317] For example, a filter screen is arranged in the first bin 310, and the first bin 310 can be used as a solid-liquid separation bin, and the first detection assembly 361 can be used to detect the capacity of solid waste. The second bin 320 is mainly used for storing liquid, and therefore the second detection assembly 362 can be used to detect the liquid level inside the second bin 320. When the containing object in any bin is full, the user will be notified to maintain the cleaning device 10, thereby improving the reliability and preventing the user from continuing to use the cleaning device 10 after the other bin is full, which may cause damage to the cleaning device 10 or leakage of liquid waste affecting the cleaning effect.

[0318] In an optional embodiment, as shown in Figure 57 、 58 The first detection assembly 361 and the second detection assembly 362 are connected in parallel with the first detection assembly 361, wherein the first detection assembly 361 is arranged in the first bin 310, and the second detection assembly 362 is arranged in the second bin 320. Here, the first detection assembly 361 and the second detection assembly 362 are connected in parallel, and either one of them can trigger a corresponding prompt. The number of the first detection assembly 361 can be more than one, and they are arranged in different positions of the first bin 310.

[0319] In an optional embodiment, the first detection assembly 361 is located in the first bin 310, and the second detection assembly 362 is located in the second bin 320. For example, it can be located on the inner side wall of the first bin 310 or at the center of the cavity of the first bin 310.

[0320] Furthermore, the cleaning device 10 also includes an electrical connector 364, which is connected to the first detection component 361 and the second detection component 362 respectively (e.g., Figure 57 As shown), the electrical connector 364 serves to lead out the signal; the exemplary first detection component 361 or second detection component 362 can be a photodetector; a capacitance detector; or an electrode detector.

[0321] In other embodiments, such as Figure 58 As shown, the first detection component 361 and the second detection component 362 are formed from portions of the electrical connector 364. Exemplarily, the electrical connector 364 itself has conductive properties and can also function as an electrode; therefore, as... Figure 58 As shown, the electrical connector 364 is placed inside the wall of the first compartment 310, and a connection hole 367 is provided on the wall to connect the space inside the compartment to the electrical connector 364. Thus, the electrical connector 364 can be directly used as a detection component, which can simplify the process. The detection component and the signal transmission component can be integrally formed, resulting in high reliability.

[0322] Regarding the specific configuration of the electrical connector 364, in some embodiments, such as Figure 57 , 58 As shown, the electrical connector 364 can be disposed on the surface of the wall of the first compartment 310, i.e., on the first housing 310a; for example, the electrical connector 364 is disposed on the surface of the first housing 310a; or, the first housing 310a has a mounting groove or mounting hole extending in the vertical direction, and the electrical connector 364 is located in the mounting groove or mounting hole. The electrical connector 364 also includes a contact 365, which is used to output a signal from the electrical connector 364 and to connect with the control device 600 of the cleaning equipment 10; when the water tank 300 is installed in place, the contact 365 is connected to the control device 600 for signal transmission, and when the water tank 300 is removed, the contact 365 is disconnected from the control device 600. Contact 365 is located on the outer side wall of the first housing 310a; and when the first housing 310a is nested in the second housing 320a, contact 365 is located on the outer side wall of the first housing 310a and is exposed in the second housing 320a.

[0323] For example, the bottom of the electrical connector 364 extends into the second compartment 320 to form the second detection component 362. The first compartment 310 has a connection hole 367 in its wall, which connects the mounting slot or mounting hole to the first compartment 310. The middle part of the electrical connector 364 is connected to the first compartment 310 through the connection hole to form the first detection component 361.

[0324] In an optional embodiment, the second detection assembly 362 is arranged on the upper portion of the second bin 320; and / or, the first detection assembly 361 is arranged on the inner side wall 310c of the first bin 310, and the second detection assembly 362 can be arranged on the bottom of the second housing 320a, and can also be arranged on the inner side wall 310c of the first bin 310, which is not limited in the present application.

[0325] In an optional embodiment, the electrical connection 364 is two, the first detection assembly 361 includes a first electrode 3611 and a second electrode 3612 connected to the two electrical connections 364 respectively; the first electrode 3611 and the second electrode 3612 are both located in the first bin 310.

[0326] Since the trigger condition of the first detection assembly 361 requires the first electrode 3611 and the second electrode 3612 to be conductive, the positions of the first electrode 3611 and the second electrode 3612 need to be designed to prevent false positives.

[0327] Among them, the first electrode 3611 and the second electrode 3612 are different in height; the height difference is used to reduce the formation of water film.

[0328] At least one of the first electrode 3611 and the second electrode 3612 is located at the top of the first bin 310, which is arranged to ensure that the first bin 310 is full and triggered. At least one of the first electrode 3611 and the second electrode 3612 is arranged at the bottom of the first bin 310.

[0329] At least one of the first electrode 3611 and the second electrode 3612 extends downward from the top wall of the first bin 310, and forms a gap between the side wall of the first bin 310, which is arranged to reduce the formation of water film between the first electrode 3611 and the second electrode 3612, and prevent false positives.

[0330] The first electrode 3611 and the second electrode 3612 are arranged on both sides of the first bin 310; for example, they can be arranged on both sides of the sewage suction pipe 112, which separates the first electrode and the second electrode by the sewage suction pipe 112 to reduce the probability of water film formation. At the same time, such arrangement can take into account the space of the first bin 310; prevent the contents in the first bin 310 from being stacked on one side while the other side still has space and is triggered, forming a false positive.

[0331] For example, at least one of the first electrode 3611 and the second electrode 3612 is arranged at the top or middle of the first bin 310, when the contents in the first bin 310 are more, and the electrode at the top is contacted, the two electrodes will be conductive due to the contents, to trigger the signal that the contents in the first bin 310 have reached the detection position.

[0332] In an alternative embodiment, one of the first electrode 3611 and the second electrode 3612 is arranged at the top of the first chamber 310, and the other of the first electrode 3611 and the second electrode 3612 is arranged at the bottom of the first chamber 310.

[0333] In an alternative embodiment, the electrical connector 364 is two, the second detection assembly 362 includes a third electrode and a fourth electrode connected to the two electrical connectors 364 respectively, and one of the third electrode and the fourth electrode is arranged on the bottom surface of the first chamber 310. At least one of the third electrode and the fourth electrode can also extend downward from the bottom wall of the first chamber 310 and form a gap with the side wall of the second chamber 320; so as to reduce the formation of water film between the third electrode and the fourth electrode. Thus, the third electrode and the fourth electrode are arranged in the first housing 310a, which simplifies the structure and processing of the second housing 320a, and the second detection assembly 362 is arranged through the bottom of the first housing 310a, and when the first housing 310a is installed in place, the second detection assembly 362 plays a detection role on the contents in the second housing 320a.

[0334] In an alternative embodiment, the bottom surface of the first chamber 310 is provided with a supporting protrusion, wherein the lower edge of the third electrode and / or the fourth electrode is higher than the bottom of the supporting protrusion, so that the supporting protrusion can support the first chamber 310 after it is taken out, prevent the third electrode and / or the fourth electrode from contacting or colliding with the placement surface, and protect the third electrode and / or the fourth electrode. At the same time, it can also assist the first chamber 310 to stand after being taken out.

[0335] In an alternative embodiment, referring to Figure 60 , the cleaning device 10 further includes a third detection assembly 363, the third detection assembly 363 includes a fifth electrode 3631 and a sixth electrode 3632, and the second chamber 320 is further communicated with a second suction passage 321. At least one of the fifth electrode 3631 and the sixth electrode 3632 is arranged in the second suction passage 321, and when liquid enters the second suction passage 321, the electrode located in the second suction passage 321 will be conductive with the other electrode, that is, the third detection assembly 363 can play a role in detecting water entering the second suction passage.

[0336] In an alternative embodiment, as Figure 60 shown, the fifth electrode 3631 and / or the sixth electrode 3632 arranged in the second suction passage 321 form a partition 321c arranged in the second suction passage 321, that is, the fifth electrode 3631 and / or the sixth electrode 3632 located in the second suction passage can detect the liquid state in the suction passage, and the partition-shaped third electrode and / or fourth electrode can also directly block the liquid entering the suction passage.

[0337] In an optional embodiment, a plurality of baffles 321c are arranged in the second suction channel 321, and the third electrode and / or the fourth electrode arranged in the suction channel are arranged alternately with the plurality of baffles 321c, forming a meandering airflow channel, which blocks the liquid and allows the gas to pass through, further preventing the liquid from being directly sucked into the gas suction device.

[0338] In an optional embodiment, the first detection assembly 361 is arranged on the front side of the first tank 310, so as to avoid the liquid contacting the first detection assembly 361 when the first tank 310 is in the lying state, and to avoid the first detection assembly 361 from misjudging.

[0339] In an optional embodiment, the first detection assembly 361 is arranged on the rear side of the top of the first tank 310, which can be used to detect the backflow of the liquid in the first tank 310 when the cleaning device 10 is lying down, and to trigger in time.

[0340] In an optional embodiment, the second detection assembly 362 is arranged on the front side of the second tank 320, so as to avoid the liquid contacting the second detection assembly 362 when the second tank 320 is in the lying state, and to avoid the second detection assembly 362 from misjudging. The first detection assembly 361 and / or the second detection assembly 362 are arranged on the front side, and the distance between the first detection assembly 361 and / or the second detection assembly 362 and the water level is the largest when the main body 100 is lying down, which can avoid the lying down directly triggering the first detection assembly 361 and / or the second detection assembly 362 due to the change of the water level. Meanwhile, the first detection assembly 361 and / or the second detection assembly 362 are arranged on the same side as the air suction port 317 and the first suction channel 311 and the second suction channel 321, and when the water level rises to affect the working state of the air suction port 317, the first detection assembly 361 and / or the second detection assembly 362 can perform synchronous detection.

[0341] In an optional embodiment, a blocking edge structure is arranged around the outside of the position of the first detection assembly 361 on the wall of the first tank 310 and / or the second detection assembly 362 on the wall of the second tank 320, which can avoid the water film formed on the inner wall of the first tank 310 or the second tank 320 due to the surface tension of the liquid from connecting the first detection assembly 361 and / or the second detection assembly 362, so as to avoid the wall of the first tank 310 or the second tank 320 affecting the misjudgment of the first detection assembly 361 or the second detection assembly 362.

[0342] In an optional embodiment, the first detection assembly 361 and / or the second detection assembly 362 and / or the third detection assembly 363 are photoelectric detectors. That is, the first detection assembly 361, the second detection assembly 362, and the third detection assembly 363 can be electrode type detectors or photoelectric type detectors, and can be combined at will.

[0343] As Figures 54-56 shown, according to the second aspect of the present application, the embodiments of the present application provide a cleaning device 10, comprising a chassis 200, a main body 100, a first bin 310, a second bin 320 and a first suction device 400, wherein the main body 100 is rotationally connected with the chassis 200, the first bin 310 is arranged on the main body 100, the second bin 320 is in communication with the first bin 310, the first suction device 400 is in communication with the first bin 310 through a first suction passage 311, the first suction device 400 provides power for driving external liquid into the first bin 310, the first suction device 400 is also in communication with the second bin 320 through a second suction passage 321, and the first suction device 400 provides power for the liquid in the first bin 310 to enter the second bin 320, so that one first suction device 400 can be used to provide power for the external liquid to be sucked into the first bin 310 and to provide power for the liquid in the first bin 310 to enter the second bin 320, the first suction device 400 sucks the first bin 310 and the second bin 320 through the first suction passage 311 and the second suction passage 321 which are independent of each other, when the external liquid is sucked into the first bin 310, the gas is sucked out through the first suction passage 311, the liquid is sucked into the second bin 320 through the liquid leakage structure 312 which connects the first bin 310 and the second bin 320 and is stored, so that the liquid in the first bin 310 is always less, avoiding the liquid in the first bin 310 being filled, or when the cleaning device 10 is in a state of shaking, tilting or lying down, avoiding the liquid in the first bin 310 entering the first suction device 400, and because the first suction device 400 also has a certain suction effect on the liquid leakage structure 312, it can effectively prevent the liquid in the second bin 320 from flowing back to the first bin 310, and the structure is simple and practical. Compared with the scheme as Figures 4-6 shown, the scheme only needs to use one power source, i.e. the first suction device 400, to realize the suction and recovery of external liquid, while reducing the probability of water entering the first suction device 400, thereby saving cost.

[0344] In an optional embodiment, the cleaning device 10 comprises a suction pipe 311 for connecting the first bin 310 and the outside; the first suction passage 311 comprises a suction port 317 arranged on the first bin 310, and the first suction device 400 is in communication with the first bin 310 through the suction port 317 to provide negative pressure for the first bin 310, so that the liquid outside can enter the first bin 310 from the suction pipe 311.

[0345] In an optional embodiment, the second suction channel 321 includes all or part of a side wall 310c of the first housing 310a, wherein the first suction device 400 is connected to the second chamber 320 through the second suction channel 321 to provide negative pressure to the second chamber 320. This allows the liquid in the first chamber 310 to enter the second chamber 320 not only by gravity, but also by the suction force of the first suction device 400 to help the liquid in the first chamber 310 to enter the second chamber 320 more quickly.

[0346] In an optional embodiment, the cross-sectional area of ​​the first suction channel 311 is smaller than that of the second suction channel 321, so that a negative pressure difference can be formed between the first chamber 310 and the second chamber 320 under the action of a suction device, so that the liquid in the first chamber 310 can enter the second chamber 320 better.

[0347] In one alternative implementation, the negative pressure in the second chamber 320 is greater than that in the first chamber 310, allowing the liquid in the first chamber 310 to enter the second chamber 320 more effectively.

The second compartment 320 is connected to the first compartment 310 and is connected to a second suction device 500, which provides power to drive liquid from the first compartment 310 into the second compartment 320.

[0349] like Figures 1 to 56As shown, according to the fourth aspect of the present application, the embodiments of the present application provide a water tank 300 configured to be mounted on a main body 100 of a cleaning device 10, wherein the main body 100 is rotatably connected to a chassis 200 of the cleaning device 10. The water tank 300 comprises a first tank 310 and a second tank 320, wherein the first tank 310 is arranged on the main body 100, and the second tank 320 is in communication with the first tank 310. The cleaning device 10 comprises a first suction device 400, wherein the first suction device 400 is in communication with the first tank 310 through a first suction passage 311, and the first suction device 400 provides power for driving external liquid into the first tank 310. The first suction device 400 is also in communication with the second tank 320 through a second suction passage 321, and the first suction device 400 provides power for the liquid in the first tank 310 to enter the second tank 320.
