Description

[0001] The filing date of this application is August 17, 2022, and the filing date is July 24, 2024. It is a divisional application of application number 202290000864.1, entitled "Cleaning Equipment and Water Tank Thereof"; Application No. 202290000864.1 is an application for the PCT international application with an application date of August 17, 2022 and application number PCT / CN2022 / 113165 to enter the Chinese national phase. Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and a water tank thereof. Background Art

[0003] With the continuous improvement of cleaning requirements and cleaning technology, various floor scrubbers have appeared in the field of cleaning and maintenance of various hard floors such as floors, tiles, marble, etc. Their working principle is generally that the roller brush body at the front end of the cleaning component rotates to clean the floor. While the roller brush body rotates, clean water flows out from the roller brush body to clean the stains, oil and impurities on the floor, and then the dirt is sucked back by the negative pressure device and stored in the cleaning equipment.

[0004] However, when the user uses or maintains the floor scrubber, the liquid in the cleaning equipment is likely to flow back from the sewage tank or the clean water tank or be drawn into the negative pressure device 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 in the cleaning equipment shell, causing secondary pollution to the equipment to be cleaned. The solution in the prior art is usually to limit the lying angle of the main body of the cleaning equipment to reduce the risk of water entering the negative pressure device, but this solution will result in a limited use angle of the floor scrubber.

[0108] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0109] It should also be understood that the terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0110] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0111] In some implementations of the present application, the following embodiments and features thereof may be combined with each other unless there is any conflict.

[0112] In some embodiments of this application, see Figure 1-3 The cleaning device 10 comprises a main body 100 and a chassis 200. The main body 100 is rotatably mounted on the chassis 200. The main body 100 has a handle 110 for a user to hold. During operation, the user holds the handle 110 and uses the main body 100 to push the chassis 200 to control the cleaning device 10 to move forward, backward, or turn, thereby using the cleaning member 210 on the chassis 200 to clean the surface to be cleaned. The cleaning device 10 generally comprises a clean water tank and a dirty water tank. The clean water tank supplies water to the cleaning member 210 or the ground. The water can moisten the surface to be cleaned, allowing the cleaning member 210 to better clean dirt on the ground. During the cleaning process, the cleaning device 10 uses the first suction device 400 (such as a negative pressure source such as a fan) to recycle the generated dirt into the sewage tank. The first suction device 400 needs to be connected to the sewage tank. However, when the sewage tank or part of the sewage tank is located on the main body 100 of the cleaning device, during the operation of the cleaning device, since the main body 100 may shake, tilt (compared to the horizontal plane) or be horizontal (compared to the horizontal plane), water or water vapor in the sewage tank can easily enter the first suction device 400, thereby causing water to enter the first suction device 400 or even be damaged. In particular, the smaller the angle between the main body 100 and the horizontal plane, the greater the probability of water entering the first suction device 400. Therefore, in order to ensure that the first suction device 400 does not enter water, the related art usually limits the angle at which the main body 100 can rotate relative to the chassis 200. This solution makes it impossible for the cleaning device 10 to clean low areas such as under the bed and sofa. Based on this, the embodiment of the present application proposes the following solution:

[0113] like Figure 1-3 As shown, the first aspect of an embodiment of the present application provides a cleaning device 10, including 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 to the chassis 200.

[0114] It should be noted that the main body 100 is rotatably connected relative to the chassis 200 so that the main body 100 can be in an upright state (such as Figure 1 ), tilted state (such as Figure 2 ), lying down (such as Figure 3) and other state switching. Among them, in the length direction of the main body 100 (such as Figure 1 When the length direction of the main body 100 is approximately parallel to the chassis 200 (or the horizontal plane), the cleaning device 10 is in a lying state, which is usually the extreme working posture of the cleaning device 10 when it is working, and is used to clean low areas, such as under beds and sofas.

[0115] In some embodiments, as Figure 4 As shown, the first compartment 310 can be provided on the main body 100, and the second compartment 320 can be provided on the chassis 200; in some other embodiments, such as Figure 5 、 6 As shown, the first bin 310 and the second bin 320 are both provided on the main body 100. Accordingly, the first suction device 400 and the second suction device 500 can be provided on the main body 100 at the same time, or the first suction device 400 can be provided on the main body 100 and the second suction device 500 can be provided on the chassis 200, or even the first suction device 400 and the second suction device 500 can be provided on the outside of the cleaning device 10, which is not limited in the present application.

[0116] How to form the first bin 310 and the second bin 320, as shown in FIG. Figure 4-6 As shown, in some embodiments, the cleaning device 10 may include a first shell 310a and a second shell 320a. The first shell 310a is formed with the above-mentioned first bin 310, and the second shell 320a is formed with the above-mentioned second bin 320. The first shell 310a can be fixed to the outside of the second shell 320a by assembly (such as Figure 5 or, the first shell 310a is provided on the main body 100, and the second shell 320a is provided on the chassis 200 (as shown); Figure 4 As shown). At this time, the first shell 310a and the second shell 320 are independent of each other, so the two can be Figure 4 As shown, they are assembled and fixed to the main body 100. The assembly setting here refers to being installed and fixed together by means of snaps, buckles, etc.; Figure 4 As shown, they are separated and placed on the main body 100 and the chassis 200 respectively. Figure 6 As shown, the cleaning device 10 includes a first shell 310a and a second shell 320a, and at least a portion of the first shell 310a is nested in the second shell 320a. Figure 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 chamber 320; the first shell 310a forms the first chamber 310 (as shown in FIG. Figure 7 、 8 Alternatively, a portion of the inner wall of the first shell 310a and a portion of the inner wall of the second shell 320 together form the first bin 310 (as shown in FIG. Figure 9 、 10 shown).

[0117] In addition, it should be noted that the external liquid described in the embodiments of this application can be waste (including solid-liquid mixtures and sewage) or clean water. The first suction device 400 in the embodiments of this application primarily provides driving force for the external liquid to enter the first chamber 310. The external portion refers to the area outside the first chamber 310 and the second chamber 320.

[0118] When the sucked liquid is sewage or a solid-liquid mixture, the water tank 300 is a sewage tank, and the first suction device 400 can recycle the dirt generated during the cleaning process of the cleaning equipment 10 into the sewage tank to facilitate subsequent processing by the user.

[0119] When the sucked liquid is clean water, the first suction device 400 can pump the external clean water into the first chamber 310. When the first chamber 310 and the second chamber 320 form a sewage tank, the clean water can be used to clean the first chamber 310 and / or the second chamber 320 to maintain the water tank.

[0120] The following mainly uses the example of the external liquid being a solid-liquid mixture or sewage for explanation.

[0121] like Figure 4-6As shown, the first suction device 400 can be used to suck external dirt (including solid and liquid garbage, sewage, etc.) collected during the cleaning process of the cleaning device 10 into the first bin 310, so as to recover stains, oil or impurities on the ground. The cleaning device 10 can also suck a mixture of external solid garbage and sewage into the first bin 310, which is not limited in this application. The chassis 200 of the cleaning device 10 is provided with a cleaning member 210 for cleaning the surface to be cleaned. The cleaning member 210 can be a cleaning member such as a roller brush. A handle 110 is provided at one end of the main body 100 for the user to hold. The user holds the handle 110 to drive the main body 100 to push the chassis 200 forward, backward or turn. The first bin 310 is provided on the main body 100, the second bin 320 is connected to the first bin 310, and the first suction device 400 is connected to the first bin 310, so that the first suction device 400 can provide power to drive external liquid into the first bin 310. For example, the first suction device 400 can be a high-flow negative pressure source such as a fan that can provide negative pressure, so as to suck the external liquid into the first chamber 310. The second chamber 320 is connected to the first chamber 310. The second chamber 320 can be understood as being indirectly connected to the first suction device 400 through the first chamber 310. When the communication channel between the first chamber 310 and the second chamber 320 is blocked, the first suction device 400 is only connected to the first chamber 310.

[0122] like Figure 4-10 As shown, there is a partition between the first warehouse 310 and the second warehouse 320 (the partition can be the bottom wall and / or side wall of the first warehouse 310) to make the first warehouse 310 and the second warehouse 320 relatively independent, and then the partition prevents the liquid in the second warehouse 320 from flowing back to the first warehouse 310; and the first warehouse 310 and the second warehouse 320 are connected, which means that there is a channel for liquid circulation between the two, wherein "channel" includes but is not limited to holes, pipes, gaps, etc., which is used to allow the liquid in the first warehouse 310 to enter the second warehouse 320.

[0123] The second suction device 500 is connected to the second chamber 320 and can provide power to drive the liquid in the first chamber 310 into the second chamber 320 , thereby further preventing the liquid in the second chamber 320 from flowing back to the first chamber 310 from the channel for liquid circulation.

[0124] In this embodiment of the present application, by adding a second suction device 500 to drive liquid from the first chamber 310 to the second chamber 320, the amount of liquid in the first chamber 310 can be reduced or liquid can be removed from the first chamber 310, thereby reducing the risk of liquid ingress into the first suction device 400. It should be noted that the first suction device 400 is used to drive external liquid into the first chamber 310, and its suction path is longer, requiring a higher suction flow rate. The second suction device 500, on the other hand, is used to drive liquid from the first chamber 310 to the second chamber 320, and its required suction flow rate can be slightly lower. When the second suction device 500 is a gas suction device, it also carries a certain risk of liquid ingress. However, it is understood that when faced with the same amount of liquid to be pumped, the greater the suction flow rate, the greater the risk of liquid ingress. Since the suction flow rate required to drive liquid from the first chamber 310 to the second chamber 320 can be smaller, a second suction device 500 with a smaller suction flow rate can be selected, thereby reducing the risk of liquid ingress into the second suction device 500. Because the flow rate required to drive the liquid in the first chamber 310 to the second chamber 320 can be relatively small, the wind resistance of the suction channel connected to the second suction device 500 can be further increased, for example by adding a blocking structure to prevent water and / or water vapor from entering the second suction device 500, thereby further reducing the risk of liquid ingress into the second suction device 500. How to design a blocking structure to reduce the risk of liquid ingress into the second suction device 500, as well as the specific form of the blocking structure, will be described in detail in subsequent embodiments.

[0125] 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 large suction flow to maintain the state of sucking external liquid into the first bin 310, the design of the blocking structure can be slightly simpler to appropriately reduce 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 always providing a large suction flow.

[0126] In some embodiments, the second suction device 500 includes a gas suction device, and the first bin 310 and the second bin 320 are connected through a liquid leakage structure 312. 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 difference in area between the two is small. For example, it is less than 20 square millimeters. Setting the cross-sectional areas of the two to be similar can enable the "suction" force of the second suction device 500 to act on the liquid leakage structure 312 at a ratio close to 1:1, thereby improving the smoothness of the liquid in the first bin 310 entering the second bin 320 through the liquid leakage structure 312.

[0127] In the embodiment of the present application, since the first suction device 400 is directly connected to the first warehouse 310, and the first warehouse 310 contains liquid recovered from the outside, during the operation of the cleaning device 10, especially when the liquid in the first warehouse 310 is filled or the main body 100 is in a tilted state or lying down, the liquid in the first warehouse 310 can easily enter the first suction device 400 directly from the first warehouse 310. By setting the second suction device 500, the second suction device 500 is connected to the second warehouse 320, and the second suction device 500 provides power to drive the liquid in the first warehouse 310 into the second warehouse 320, so that the liquid in the first warehouse 310 is always less. In this way, the liquid in the first warehouse 310 can be prevented from entering the first suction device 400 when the main body 100 is shaking, tilting, or lying down, thereby reducing the risk of liquid entering the first suction device 400, causing secondary pollution or even damage. Furthermore, the second suction device 500 can effectively prevent the liquid in the second bin 320 from flowing back into the first bin 310 and causing a potential failure of the first suction device 400 .

[0128] It should be noted that the first suction device 400 and the second suction device 500 are independent suction sources, and their suction power can be independently controlled. For example, while the first suction device 400 provides driving power to draw a solid-liquid mixture, sewage, or clean water into the first chamber 310, the suction power may be adjusted based on environmental factors. The second suction device 500, however, can maintain a high power in all circumstances to ensure that liquid is drawn from the first chamber 310 into the second chamber 320.

[0129] In some embodiments, as Figure 11 As shown, the cleaning device 10 may also include a posture detection device 700 and a control device 600. The posture detection device 700 is used to detect the current motion state parameters of the cleaning device 10. The control device 600 is connected to the posture detection device 700 and the first suction device 400 and / or the second suction device 500 (which can be a wired connection or a wireless connection) and is used to adjust the operating parameters of the first suction device 400 and / or the second suction device 500 according to the current motion state parameters of the cleaning device 10 detected by the posture detection device 700, so as to reduce the possibility of the liquid in the first bin 310 entering the first suction device 400 and / or the second suction device 500.

[0130] Exemplarily, the motion state parameters of the cleaning device 10 detected by the posture detection device 700 include 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 device 10, the motion acceleration of the cleaning device 10, and at least one of the height of the first bin 310 and 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 state, a tilted state or a lying state. The posture detection device 700 can even detect the speed or acceleration of the cleaning device 10 during movement during operation. If the main body 100 is in a lying state or the cleaning device 10 shakes too much (that is, the acceleration is too large) 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 be used to 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, so as to reduce the risk of the cleaning device 10 shaking, tilting or the main body 100 being in a lying state, causing the liquid in the first bin 310 and / or the second bin 320 to enter the first suction device 400 and / or the second suction device 500.

[0131] In some embodiments, as Figure 1 As shown, the cleaning device 10 includes a water tank 300, with a first compartment 310 and a second compartment 320 formed therein. If waste is collected, the water tank 300 serves as a sewage tank. When the cleaning device 10 is in an upright position, the first compartment 310 is located above the second compartment 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 disposed on the main body 100, enabling the first suction device 400 to draw liquid from the outside into the first compartment 310 of the water tank 300, and the second suction device 500 to draw liquid from the first compartment 310 into the second compartment 320.

[0132] In some embodiments, as Figure 7 As shown, the cleaning device 10 may further include a first detection component 361, and the control device 600 is connected to the first detection component 361. The first detection component 361 is disposed in the first bin 310 and is used to detect information about the contents of the first bin 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 based on the information about the contents detected by the first detection component 361. The information about the contents may include information about the volume of solid waste, liquid level, the presence or absence of water, etc.

[0133] For example, a filter screen 352 may be provided in the first bin 310 to form a solid-liquid separation bin, and the content information may indicate the capacity of solid waste.

[0134] For example, the first detection assembly 361 in the first chamber 310 is disposed above the first chamber 310 ;

[0135] For example, the first detection component 361 in the first bin 310 is arranged on the rear side above the first bin 310. Such an arrangement allows the cleaning device to be in a lying state. If liquid triggers the first detection component 361, it means that the first suction device 400 is at risk of liquid ingress.

[0136] Furthermore, it may also include a prompt device (not shown), which is electrically connected to the first detection component 361, so that when the amount of dirt in the first bin 310 reaches a preset value or is triggered, the prompt 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 backflow of liquid in the first bin 310 and the second bin 320.

[0137] For example, the control device 600 is connected to the first detection assembly 361 and 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 to reduce or shut down 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.

[0138] At the same time, when the amount of dirt in the first bin 310 is large (for example, there is a lot of solid waste in the first bin 310), the liquid in the first bin 310 will not easily enter the second bin 320 to a certain extent. Therefore, in this scenario, the operating parameters of the second suction device 500 can be adjusted through the control device 600 to increase the suction force of the second suction device 500, so that the second suction device 500 provides a greater suction force to be able to more fully suck the liquid in the first bin 310 to the second bin 320.

[0139] It should be noted that the first detection component 361 detects the amount of dirt in the first bin 310, including the detection of solids, viscous substances or liquids in the first bin 310, and the specific detection methods adopted include but are not limited to the detection of dirt height, the detection of dirt weight, and even the direct visual detection of the amount of dirt, which is not limited in this application.

[0140] In one embodiment, the cleaning device includes a second detection component 362, which detects information about the contents of the second chamber. For example, when the amount of dirt in the second chamber 320 reaches a preset amount, the control device 600 can adjust the operating parameters of the second suction device 500 to reduce or shut down the suction force of the second suction device 500, thereby reducing the possibility of liquid in the second chamber 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 chamber 320 reaches a preset amount, the control device 600 can also reduce or shut down the suction force of the first suction device 400, thereby preventing the liquid in the second chamber 320 from continuing to increase.

[0141] Exemplarily, 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, and 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 external liquid can enter the first chamber 310 and the liquid in the first chamber 310 can enter the second chamber 320. 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 chamber 310 and / or the second chamber 320. In particular, when the amount of liquid dirt is large, the suction device can be turned off in time or the suction force of the suction device can be reduced (the greater the suction force, the greater the operating power required, 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.

[0142] On the other hand, because the operating parameters of the second suction device 500 can be flexibly adjusted based on the amount of dirt in the first bin 310, the operating power of the second suction device 500 can be reduced when the amount of dirt in the first bin 310 is low, and the operating power of the second suction device 500 can be increased when the amount of dirt in the first bin 310 is high. By matching the amount of dirt in the first bin 310 with the operating parameters of the second suction device 500, dynamic adjustment of the operating parameters of the second suction device 500 is achieved. This avoids the problem of the second suction device 500 always operating at a high power and causing high operating noise, reduces the impact of operating noise on the user experience, and effectively improves the user experience.

[0143] It should be noted that, in order to clearly indicate the orientation, the embodiment of the present application defines the front side, rear side, left side, and right side of the cleaning device 10; Figure 1As shown, the front side refers to the side of the cleaning device 10 that moves forward in a non-turning state; the rear side refers to the side opposite to the front side, that is, the side of the cleaning device 10 that moves away from the forward direction in a non-turning state; the left side refers to the left hand side when the user stands facing forward; and the right side refers to the right hand side when the user stands facing forward. As for the main body 100, the front side refers to the side that the main body 100 swings forward, and the rear side refers to the side that the main body 100 swings backward. The swing angle of the main body 100 will change. When the main body 100 is in an upright state (such as Figure 1 ), the front side is the side of the forward direction of the cleaning device 10 in the non-turning state, and when the main body 100 is in the lying state (such as Figure 3 ), the front side is the upper side of the main body 100 at this time, and the rear side is the lower side of the main body 100 at this time.

[0144] In some embodiments, see Figure 4-10 The first chamber 310 and the second chamber 320 are connected via a liquid leakage structure 312, so that the liquid in the first chamber 310 can enter the second chamber 320. The liquid leakage structure 312 can be a leaking hole, a leaking channel, or a leaking gap, etc., provided between the first chamber 310 and the second chamber 320, and is not limited in this application. It should be noted that the leakage area formed by the liquid leakage structure 312 can be as small and concentrated as possible; for example, the ratio of the area of ​​the liquid leakage structure 312 to the cross-sectional area of ​​the water tank 300 is less than 1 / 4, or less than 1 square centimeter. For example, the cross-sectional area of ​​the liquid leakage structure 312 is less than 1 / 4 of the bottom area of ​​the first chamber 310. So that the rest of the bottom wall of the first shell 310a can isolate the first warehouse 310 and the second warehouse 320, and the suction force of the second suction device 500 is concentrated on the smaller leakage structure 312, which can quickly suck the liquid in the first warehouse 310 into the second warehouse 320. In this way, the risk of liquid flowing back from the second warehouse 320 to the first warehouse 310 or the surge of liquid returning to the first warehouse 310 when the cleaning equipment 10 shakes can be reduced, so that most of the liquid remains in the second warehouse 320, reducing the amount of liquid retained in the first warehouse 310, and thus reducing the risk of liquid intrusion into the first suction device 400.

[0145] It should be noted that when the first chamber 310 is located above the second chamber 320 , the force acting on 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 .

[0146] In some embodiments, the liquid leakage structure 312 can be disposed on the rear side of the first compartment 310. This allows the liquid leakage structure 312 located on the rear side of the first compartment 310 to be located at the lowest point of the first compartment 310 when the main body 100 is tilted backward or lying down, making it easier for liquid in the first compartment 310 to flow into the second compartment 320 during use or when lying down.

[0147] In some embodiments, the liquid leakage structure 312 can be disposed at the lower portion of the first compartment 310. The lower portion of the first compartment 310 refers to the side or bottom wall of the sidewall 310c of the first compartment 310 that is closer to the chassis 200. The liquid leakage structure 312 disposed at the lower portion allows the liquid leakage structure 312 to be located at the bottom of the first compartment 310 when the main body 100 is tilted or upright, allowing all liquid in the first compartment 310 to flow into the second compartment 320 through the liquid leakage structure 312.

[0148] In some embodiments, the leakage structure 312 is arranged at the lower rear side of the first compartment 310. At this time, no matter whether the main body 100 is tilted, upright or lying down, the leakage structure 312 can be ensured to be located at the bottom of the first compartment 310 in the current state, so that all the liquid in the first compartment 310 can flow into the second compartment 320 through the leakage structure 312.

[0149] In an alternative embodiment, see Figure 12 The maximum dimension of the liquid leakage structure 312 in the front-to-back direction is smaller than the minimum dimension in the left-to-right direction, so that the liquid leakage structure 312 can be closer to the rear side, while also ensuring the circulation efficiency of the liquid leakage structure 312. For example, the liquid leakage structure 312 can be flat.

[0150] In an optional embodiment, the number of the liquid leakage structure 312 is one or more.

[0151] In the embodiment of the present application, the second suction device 500 can be a gas suction device such as a vacuum pump or a blower, or a liquid suction device such as a water pump or a peristaltic pump. Of course, the present application is not limited to these devices, as long as they can provide power to drive the liquid in the first chamber 310 to the second chamber 320. The following description will first take the second suction device 500 as a gas suction device as an example.

[0152] In some embodiments, the second suction device 500 includes a gas suction device 500, which is in communication with the second chamber 320 and is configured to suck gas from the second chamber 320 to create a negative pressure within the second chamber 320. In this manner, in addition to the liquid in the first chamber 310 flowing into the second chamber 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 chamber 310 to the second chamber 320. The gas suction device 500 can be a device capable of sucking gas, such as a vacuum pump, an air pump, or a fan.

[0153] like Figure 4-6As shown, the first suction device 400 is connected to the first chamber 310 through the first suction channel 311, and the second suction device 500 is connected to the second chamber 320 through the second suction channel 321, so that the first chamber 310 can generate negative pressure under the action of the first suction device 400, so that external liquid can enter the first chamber 310, and then the second chamber 320, under the action of the second suction device 500, draws the liquid in the first chamber 310 into the second chamber 320. For example, as Figure 4 、 5 As shown, the second suction channel 321 is a suction interface; or, as Figure 6 As shown, the second suction channel 321 is an air passage.

[0154] It can be understood that when the first suction device 400 and the gas suction device 500 are in working state, the negative pressure of the first bin 310 at the connection point between the first bin 310 and the second bin 320 can be lower 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 very well, and because the liquid is fluid, when the cleaning equipment 10 is tilted, lying down, or shaking, the liquid in the second bin 320 will not flow back into the first bin 310, which can effectively protect the first suction device 400.

[0155] In some embodiments, a filter element may be further provided in the first chamber 310 to filter solid waste from the waste and retain it in the first chamber 310, while liquid in the waste enters the second chamber 320 under the negative pressure of the gas suction device and gravity. The design of the filter element in the first chamber 310 and its specific form will be described in detail in subsequent embodiments.

[0156] In the embodiment of the present application, compared with the related art, the cleaning device 10 is additionally provided with a 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 water ingress and damage. Therefore, in order to further reduce the risk of liquid ingress into the gas suction device 500 (second suction device 500), the embodiment of the present application proposes the following solution:

[0157] In some embodiments, see Figure 4-10 The second suction channel 321 includes an air inlet 321b and an air outlet 321a, wherein the air inlet 321b is connected to the second chamber 320, and the air outlet 321a is connected to the gas suction device 500 (second suction device 500). As for the shape of the second suction channel 321, it is not limited here.

[0158] For example, Figure 4-10 As shown, the air inlet 321b of the second suction channel 321 can be located at the front side of the second chamber 320. In this way, when the cleaning device 10 is in a lying state, the air inlet 321b can be as far away from the liquid surface in the second chamber 320 as possible to reduce the probability of the liquid in the second chamber 320 being sucked into the air inlet 321b (as shown in FIG. Figure 13 At the same time, when the cleaning device 10 is lying down, the farther the air inlet 321b is from the liquid level in the second chamber 320, the greater the volume of the second chamber 320 that can be utilized. For example, when the cleaning device 10 is lying down, if the air inlet 321b is located at the front side of the second chamber 320, the height of the liquid entering the second chamber 320 can approach the front side of the second chamber 320. However, if the air inlet 321b is located in the middle of the second chamber 320, in order to reduce the probability of liquid entering the first suction device 400 through the air inlet 321b, the height of the liquid entering the second chamber 320 can only be controlled to be lower than the middle. The former can accept a higher liquid height, resulting in the second chamber 320 storing less liquid than when the air inlet 321b is located at the front side of the second chamber 320. Therefore, locating the air inlet 321b at the front side of the second chamber 320 can increase the effectively utilized volume of the second chamber 320.

[0159] In some embodiments, as Figure 4-10 The air inlet 321b of the second suction channel 321 is located above the second warehouse 320. The above here refers to the above of the second warehouse as a whole. This setting can make the air inlet 321b away from the liquid surface of the second warehouse 320, so as to reduce the probability of the liquid in the second warehouse 320 being sucked into the second suction channel 321.

[0160] In some embodiments, as Figure 12 、 13 As shown, the maximum dimension of the air inlet 321b in the front-to-back direction of the main body 100 is smaller than the minimum dimension in the left-to-right direction of the main body 100; illustratively, the air inlet 321 may be flat; if the position of the air inlet 321b is fixed, the shape of the air inlet 321b is set so that the lowest point of the opening of the air inlet 321b can be as high as possible in the lying state, so that at the same liquid level, the bottom of the air inlet 321b can be further away from the liquid surface in the second bin 320 to reduce the probability of the liquid in the second bin 320 entering the second suction channel 321. At the same time, when the cleaning device 10 is lying down, the farther the air inlet 321b is from the liquid surface in the second bin 320, the larger the volume of the second bin 320 that can be utilized. For example, Figure 13As shown, when the cleaning device 10 is in a lying state and the air inlet 321b is flat, the height of the liquid entering the second warehouse 320 can be closer to the front side of the second warehouse 320. If the air inlet 321b is set in the second warehouse 320, it is not flat but the thickness in the front-to-back direction is increased, that is, in the lying state, the opening of the air inlet 321b is in the height direction, which 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 warehouse 320 can only be controlled to be lower than the opening position, and the corresponding effective volume of the second warehouse 320 will be reduced; therefore, setting the air inlet 321b to be flat can also increase the effective utilization volume of the second warehouse 320.

[0161] It should be noted that the second suction channel 321 may also be flat as a whole.

[0162] In addition, the air inlet 321b and / or the second suction channel 321 are also located at the front side and / or above the second chamber 320, which can further reduce the probability of liquid entering the air inlet 321b321 and increase the effective volume of the second chamber 320.

[0163] In an optional embodiment, if Figure 14 As shown, the cross-sectional area of ​​the second suction channel 321 can gradually decrease from the air inlet 321b toward the air outlet 321a. With this arrangement, the air inlet 321b can be set as large or wide as possible in a limited space, which can reduce the probability of the air inlet 321b being completely blocked by liquid. In this way, even if the air inlet 321b is partially blocked by liquid, since the fluidity of gas is greater than the fluidity of liquid, the gas suction device can still suck gas through the part of the air inlet 321b that is not blocked by liquid during suction. Therefore, the second suction device 500 set in this way can still continue to work, thereby reducing the possibility of the second suction device 500 failing due to water entering part of the air inlet 321b. In addition, since the cross-sectional area of ​​the entire second suction channel 321 gradually decreases along the suction direction of the second suction channel 321, even if liquid enters the second suction channel 321 through the air inlet 321b, since the cross-sectional area of ​​the second suction channel 321 gradually decreases, the liquid that is shaken into the second suction channel 321 is likely to collide with the inner wall of the second suction channel 321, thereby being blocked by the inner wall of the second suction channel 321 and not easily entering the gas suction device directly from the air outlet 321a.

[0164] In an optional embodiment, if Figure 15As shown, the second suction channel 321 includes at least one guide wall 321h, which is used to guide the airflow in the second suction channel 321 along a curved path from the air inlet 321b to the air outlet 321a. The guide wall 321h forms a curved path in the second suction channel 321. Even if water vapor enters the second suction channel 321 through the air inlet 321b, the water vapor must traverse the curved path in the second suction channel 321 before reaching the air outlet 321a. In other words, the path for water vapor to reach the air outlet 321a from the air inlet 321b becomes longer, which undoubtedly increases the difficulty for the water vapor to enter the second suction device 500 after finally reaching the air outlet 321a. In addition, the water vapor can also play a certain role in separating and blocking water vapor when passing through the guide wall 321h, preventing water vapor from being directly drawn into the second suction channel 321.

[0165] In some other embodiments, the guide wall 321h may be formed by bending the side wall of the second suction channel 321; or, the second suction channel 321 includes a curved side wall, and the curved side wall forms the guide wall 321h.

[0166] In some embodiments, see Figure 14-17 The second suction channel 321 is staggered with multiple partitions 321c along the suction direction, and the length direction of the partition 321c can roughly extend along the left and 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 from the second suction channel 321 into the air outlet 321a, thereby reducing the possibility of the liquid in the second chamber 320 entering the gas suction device 500.

[0167] In some embodiments, see Figure 14-16 A guide port 321d is provided on the partition 321c, or a guide port 321d is provided between the partition 321c and the side wall of the second suction channel 321, and at least two guide ports 321d are staggered. The guide port 321d and the partition 321c are used to guide the airflow along a curved path to prevent the liquid in the second chamber 320 from entering the gas suction device 500.

[0168] Exemplarily, the partition 321c may be provided with an opening, which forms the above-mentioned guide port 321d; or one end of the partition 321c is connected to the inner wall of the second suction channel 321, and a gap is left between the other end and the inner wall, and the gaps are staggered to form the above-mentioned guide port 321d.

[0169] In an optional embodiment, please refer to the attached Figure 15As shown, the guide opening 321d formed by one of two adjacent partitions 321c is located at the left end of the partition 321c, while the guide opening 321d formed by the other adjacent partition 321c is located at the right end of the partition 321c, so that the two guide openings 321d can be staggered. This can make the air flow path as long as possible, thereby maximizing the water vapor separation effect.

[0170] In some embodiments, as Figure 16 、 17 As shown, at least one of the partitions 321c is provided with at least one first opening 321k, located in the middle or at both ends of the partition 321c. At least another partition 321c is provided with at least two second openings 321m, which are offset from the first opening 321k. The first opening 321k and the second opening 321m respectively form the aforementioned guide openings 321d. Specifically, the partition 321c can be provided with more than one opening to reduce wind resistance when the gas suction device draws air from the second suction channel 321. Furthermore, there can be multiple partitions 321c with multiple openings, with the openings of adjacent partitions 321c offset to form a curved airflow path. The first opening 321k and the second opening 321m can be of different sizes.

[0171] In some embodiments, as Figure 14-16 As shown in Figure 18, the partition 321c can be set at an angle, and the guide port 321d can be set at the lowest point of the partition 321c, so that the partition 321c can conveniently block the liquid entering the second suction channel 321, and also ensure that the liquid entering the second suction channel 321 will flow out due to gravity when the main body 100 is tilted or upright.

[0172] In some embodiments, as Figure 14-18 As shown, a unit airflow channel 321e is formed between every two adjacent partitions 321c, and the cross-sectional area of ​​each unit airflow channel 321e gradually decreases along the airflow direction. If liquid enters the unit airflow channel 321e, the cross-sectional area of ​​the airflow channel gradually decreases along the airflow direction, which can make the liquid entering the unit airflow channel 321e easily impact the inner wall of the unit airflow channel 321e, and can form a certain blocking effect on the liquid. Therefore, 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.

[0173] In some embodiments, as Figure 14 、 15As shown, the minimum cross-sectional area of ​​the one closer to the air inlet 321b in each two adjacent unit airflow channels 321e is smaller than the maximum cross-sectional area of ​​the other. Such a setting can make the size of the cross-sectional area of ​​the airflow channel change periodically. Such a setting can slow down the airflow velocity entering the unit airflow channel 321e when entering the area with a larger cross-sectional area, so that the liquid entrained 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.

[0174] For example, Figure 15 As shown, the partition 321c includes a first partition 3211c and a second partition 3212c arranged alternately along the suction direction, wherein the second suction channel 321 has a first side wall 321f and a second side wall 321g arranged opposite to each other in the left and right directions, the first partition 3211c is arranged on the first side wall 321f of the second suction channel 321 and tilted downward toward the second side wall 321g, and the second partition 3212c is arranged on the second side wall 321g of the second suction channel 321 and tilted downward toward the first side wall 321f, so that the first partition 3211c and the second partition 3212c can both tilt downward and can be staggered along the up and down directions.

[0175] Furthermore, if Figure 15 As shown, a baffle 3213c may be provided on the partition 321c. The baffle 3213c is arranged at an angle to the airflow direction to block liquid from entering the second suction channel 321. By providing the baffle 3213c, at least a portion of the suction airflow can directly impact the baffle 3213c. Since the airflow carries water vapor, the water vapor impacts the baffle 3213c and flows down along the extension direction of the baffle 3213c. This further reduces the risk of liquid entering the second suction device 500 through the second suction channel 321.

[0176] For example, the extension 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 other embodiments, the extension direction of the baffle 3213c can form an acute angle with the airflow direction, as long as the baffle 3213c can block liquid in the airflow.

[0177] In some embodiments, the first side wall 321f and / or the second side wall 321g may be curved walls to form a curved airflow channel.

[0178] In some embodiments, as Figure 16As shown, multiple baffles 321c are provided in the portion of the second suction channel 321 near the air inlet 321b, while the portion of the second suction channel 321 near the air outlet 321a is not provided with any blocking member. This arrangement allows the front portion of the second suction channel 321 near the air inlet 321b to primarily prevent liquid from entering the second suction channel 321, while the rear portion of the second suction channel 321 near the air outlet 321a forms a larger space for liquid that accidentally enters the rear portion of the second suction channel 321. This larger space can slow down the liquid's velocity and allow it to flow back into the second chamber. In this case, the first sidewall 321f and the second sidewall 321g of the suction channel 321 can also be configured as straight walls.

[0179] In some embodiments, see Figure 17 、 Figure 18 The partition 321c can be detachably connected to the inner wall of the second suction channel 321 so that the partition 321c and the second suction channel 321 can be cleaned. When the second suction channel 321 is flat, it is particularly difficult to clean the inside of the second suction channel 321, and when the partition is present, it is almost impossible to clean. Therefore, the partition is set to be detachable so that the user can remove it for cleaning.

[0180] Further, see Figure 17-18 A partition frame 322 is detachably mounted on the second suction channel 321. The partition frame 322 is provided with a plurality of the aforementioned partitions 321c. The partition frame 322 is plate-shaped and, when installed, forms the second suction channel 321. The partition frame 322 can then be removed from the second suction channel 321 for cleaning, resulting in a simple and practical structure. Cleaning the second suction channel 321 is particularly difficult when the second suction channel 321 is flat. Therefore, using the partition frame 322 to remove the partitions as a whole facilitates both disassembly and cleaning.

[0181] Specifically, the arrangement of the partition frame 322 includes at least the following: Figure 17 、 18 There are two ways shown. Figure 17 As shown, a partition frame 322 is provided inside the second suction channel 321, which is removable. The partition frame 322 is composed of two support bars connected to the left and right ends of the plurality of partitions 321c. The partition frame 322 can be inserted or withdrawn from the bottom along the second suction channel 321. Alternatively, Figure 18 As shown, the partition frame 322 is a flat plate, and the partitions are all set on the flat plate. One side of the flat plate where the partition is installed forms part of the inner wall of the second suction channel 321. The user can remove the partition by removing the flat plate to open the second suction channel 321 as a whole for easy cleaning.

[0182] In some embodiments, as Figure 15 、 16 As shown, the cleaning device 10 can be provided with a third detection component 363 for detecting whether water has entered the second suction channel 321, thereby reducing the risk of failure of the gas suction device 500 due to liquid entering the second suction channel 321. When water entering the second suction channel 321 is detected, the gas suction device can be controlled to be shut down or the power of the gas suction device can be reduced to minimize the liquid entering the second suction channel 321. Optionally, the third detection component 363 can be an electrode-type sensor or a photoelectric sensor.

[0183] Specifically, if Figure 15 、 16 As shown, the third detection component 363 may include a detection electrode 323, wherein the number of the detection electrodes 323 may be two, and both detection electrodes 323 are arranged in the second suction channel 321; or, one of the detection electrodes 323 is arranged in the second suction channel 321, and the other detection electrode 323 is arranged in the upper part of the second chamber 320, and the detection electrode 323 is mainly used to detect whether water enters the second suction channel 321.

[0184] It is understood that the control device 600 can be connected to the third detection component 363 and used to control the start and stop or power level of the gas suction device 500 based on the information detected by the third detection component 363 regarding whether water has entered the second suction channel 321, thereby reducing the possibility of damage to the gas suction device 500 due to water ingress. Specifically, when a certain amount of water enters the second suction channel 321, the two detection electrodes 323 conduct, generating a water inflow signal, and the control device 600 controls the gas suction device 500 to shut down or reduce its power. When a certain amount of water flows out of the second suction channel 321, the two detection electrodes 323 disconnect, generating a water-out signal, and the control device 600 controls the gas suction device 500 to turn on or increase its power.

[0185] In an optional embodiment, if Figure 7 As shown, a second detection assembly 362 is disposed within the second chamber 320 for detecting the liquid level within the second chamber 320. In this embodiment, the second detection assembly 362 is a liquid level sensor or a water presence sensor. The liquid level information includes specific information about the liquid level within the second chamber 320, or information about the presence of water when water momentarily reaches the second detection assembly 362 during conditions such as shaking or tilting.

[0186] Exemplarily, the installation position of the second detection assembly 362 can be lower than the air inlet 321b of the second suction channel 321, and / or the installation position of the second detection assembly 362 is located behind the air inlet 321b of the second suction channel 321. The second detection assembly 362 can trigger a water signal when the liquid or liquid level reaches its installation position. At this time, the control device 600 is used to control the gas suction device to shut down or reduce the power. Therefore, the position of the second detection assembly 362 needs to be set below 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 channel 321. Such an arrangement can ensure that the second detection assembly 362 is closer to the liquid surface than the air inlet 321b, whether in an upright state, a tilted state, or a lying state. Therefore, the alarm can be triggered before the liquid enters the air inlet 321b, thereby reducing the probability of liquid entering the gas suction device through the air inlet 321b.

[0187] The following describes in detail how to form the first chamber 310, the second chamber 320, and the second suction channel 321, as follows:

[0188] In some embodiments, as Figure 4 、 Figure 5 As shown, the cleaning device 10 includes a first shell 310a and a second shell 320a. The first shell 310a is formed with the above-mentioned first bin 310, and the second shell 320a is formed with the above-mentioned second bin 320. The first shell 310a is fixed to the outside of the second shell 320a by assembly (as shown in FIG. Figure 5 As shown), the assembly method refers to installing the first shell 310a and the second shell 320 together by snapping, buckling, snapping, etc.; or, the first shell 310a is provided on the main body 100, and the second shell 320a is provided on the chassis 200 (as shown). Figure 4 With this arrangement, the gravity of the main body 100 can be reduced, making it easier for the user to push or twist the main body 100.

[0189] At this time, the first bin 310 and the second bin 320 are set independently of each other, and the air outlet 321a of the second suction channel 321 is set on the second shell 320 and located at the top of the second bin 320 for connection with the interface of the second suction device 500.

[0190] In some embodiments, see Figures 6-10 The cleaning device 10 includes a first shell 310a and a second shell 320a, wherein at least a portion of the first shell 310a is nested in the second shell 320a, wherein the second chamber 320 is formed by a portion of the inner wall of the second shell 320a and a portion of the first shell 310a (e.g. Figure 6-10); and the first chamber 310 is formed in two different ways, namely: the first chamber 310 is formed by a first shell 310a (such as Figure 7 、 8 ), or formed by enclosing part of the inner wall of the first shell 310a and part of the inner wall of the second shell 320a (such as Figure 9 、 10 ).

[0191] At this time, the first chamber 310 and the second chamber 320 are both installed on the main body 100 and are formed by the first shell 310a and the second shell 320a being nested. The second suction channel 321 can be entirely provided on the wall surface of the first shell 310a (such as Figure 19 、 20 Alternatively, part of the second suction channel 321 is provided on the wall of the first shell 310a and isolated from the first chamber 310, and the other part is formed by part of the outer wall of the first shell 310a and part of the inner wall of the second shell 320 (as shown). Figure 21 As shown), part of the inner wall of the second shell 320 forming the first bin 310 is different from part of the inner wall of the second shell 320 forming the second suction channel 321.

[0192] In some embodiments, as Figure 14-16 As shown, the first shell 310a and the second shell 320a are nested, and the outer wall groove of the first shell 310a and the inner wall of the second shell 320a are combined to form the second suction channel 321.

[0193] In some embodiments, the air outlet 321 a of the second suction channel 321 is disposed on a wall surface of the second housing 320 a .

[0194] For example, Figure 6-10 As shown in Figures 19-21, the first shell 310a is nested in the second shell 320, and the first shell 310a forms a first bin 310, and the bottom of the first shell 310a and part of the inner wall of the second shell 320 form the second bin 320. The top of the first shell 310a is sealed with the top of the second shell 320, wherein the air outlet 321a can be set above the second bin 320 in the middle of the second shell 320a to directly suck the top of the second bin 320, or it can be set at the upper part of the second shell 320a, and the top of the second bin 320 is sucked through the second suction channel 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 to dock with the interface of the second suction device 500.

[0195] In some embodiments, as Figure 19-21As shown, the first shell 310a is partially nested in the second shell 320a, and the air outlet 321a is provided on the wall of the first shell 310a and is located at the portion of the first shell 310a exposed from the second shell 320a.

[0196] For example, Figure 19-21 As shown, this scheme is Figure 7-10 Compared to the solution in

[15] , the upper portion of the first shell 310a is not completely nested within the second shell 320a, and an air outlet 321a is provided in the unnested portion of the first shell 310a. In this case, the second suction channel 321 is provided within the solid structure of the first shell 310a. A connection between the second suction channel 321 and the second chamber 320 is provided below the first shell 310a, and the second suction channel 321 and the first chamber 310a are isolated from each other within the first shell 310a. In this solution, there is no need to machine the air outlet 321a on the second shell 320a, ensuring the integrity of the second shell 320. Furthermore, since the second shell 320 is primarily used to store liquids, the integrity of the sidewalls of the second shell 320 can reduce leakage, thereby improving the stability of the second shell 320 in containing liquids.

[0197] In an optional embodiment, the first housing 310a or the second housing 320a is detachably connected to the main body 100. This allows the user to easily remove the first housing 310a and / or the second housing 320 when the first housing 310a or the second housing 320 is full of liquid or dirt to dispose of the dirt inside. The air outlet 321a is sealed and docked with the suction port of the gas suction device 500 provided on the main body 100.

[0198] In some other embodiments, such as Figure 21 As shown, when part of the second suction channel 321 is located on the wall of the first shell 310a, the rest 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.

[0199] Furthermore, if Figure 12 、 14 -16, the cleaning device 10 may include a first sealing portion 340a, the first sealing portion 340a is used to seal as described above Figure 21The outer wall of the first shell 310a and the inner wall of the second shell 320a form the remaining portion of the second suction channel 321. Since there are gaps around the remaining portion 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 at the rear side of the second chamber 320 or water between the gap between the first shell 310a and the second shell 320a can more easily enter the suction channel 321. Therefore, by providing the first sealing portion 340a, the suction force of the second suction channel 321 can be concentrated at the air inlet 321b, making it easier to control the source of liquid and further facilitate the setting of the position of the air inlet 321b, so that the cleaning device 10 will not have a significant risk of water ingress regardless of whether it is lying down, standing upright, or tilted.

[0200] When the first housing 310a is partially nested in the second housing 320, in order to ensure that the first chamber 310 and the second chamber 320 are relatively independent (connected only through the leakage structure 312) and sealed, the following design is performed:

[0201] In some embodiments, see Figure 7 、 8 A first seal 330 is disposed between the first shell 310a and the second shell 320a. The first seal 330 is squeezed between the first shell 310a and the second shell 320a to circumferentially seal the first shell 310a and the second shell 320a. In this case, the sidewall 310c of the first shell 310a is a complete sidewall. The first seal 330 is used to seal the gap between the first shell 310a and the second shell 320a, thereby forming the second chamber 320 between a portion of the outer wall of the first shell 310a and a portion of the inner wall of the second shell 320a. This prevents the liquid in the second chamber 320 from flowing out and causing leakage, and at the same time, the suction force of the gas suction device 500 can also act on the liquid leakage structure 312.

[0202] In some embodiments, see Figure 17-1921. The sidewall 310c of the first housing 310a is incomplete, that is, it has an air leakage portion 310d. A second seal 340 is also provided between the first housing 310a and the second housing 320a. The first seal 330 and the second seal 340 are spaced apart along the height of the first housing 310a, with the first seal 330 positioned above the second seal 340. The air leakage portion 310d is located between the first seal 330 and the second seal 340. Due to the presence of the air leakage portion 310d on the sidewall 310c of the first housing 310a, the airtight first chamber 310 cannot be formed. Therefore, the seal is used to isolate the first and second chambers 310, 320, and the outside world from each other, ensuring that the first and second chambers 310, 320 are relatively independent and airtight, thereby creating a negative pressure environment within the first and second chambers 310, 320.

[0203] In some embodiments, see Figure 9 、 17 -19, 21, the opening 325 of the first housing 310a forms the aforementioned air leakage portion 310d. It is understandable that when the first housing 310a is removed from the second housing 320, the opening 325 of the first housing 310a can facilitate the dumping of dirt in the first compartment 310, thereby improving the user experience.

[0204] In other embodiments, Figure 22 As shown, the side wall 310c of the first housing 310a is provided with a filter hole 352. The side filter hole 352 forms the aforementioned air leakage portion 310d. The filter hole 352 can separate the solid and liquid dirt in the first compartment 310, so that the solid waste remains in the first compartment 310, and the liquid falls into the second compartment 320 when the first housing 310a is removed from the second housing 320a. At the same time, the arrangement of the side filter hole 352, compared to the arrangement of the opening 325, can prevent the dirt in the first compartment 310 from falling when the first housing 310a is removed from the second housing 320a.

[0205] In some embodiments, as Figure 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. A gap is formed between the movable parts 310e or between the movable part 310e and the side wall 310c of the first shell 310a. The gap is located on the side wall 310c of the first shell 310a and forms the air leakage portion 310d. Because the movable part 310e forms the side of the first shell 310a, garbage is not easily dropped when the first shell 310a is removed from the second shell 320. At the same time, to facilitate the disposal of garbage in the first chamber 310, the side wall is configured as the movable part 310e, making it easier for users to operate when emptying garbage. At the same time, the movable part 310e can also be provided with a filter hole 352 to further enhance solid-liquid separation.

[0206] For example, the first housing 310a may include at least one movable member 310e that is movable with respect to each other, and the movable member 310e is connected by sliding or rotating means (for example, Figure 22-24 ), the gap between the movable parts 310e forms the above-mentioned air leakage part 310d.

[0207] In an optional embodiment, if Figure 7-8 As shown, the first housing 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. Usually, a HEPA protecting the first suction device 400 is installed above the first body 310f. A third sealing member 390 is provided between the first body 310f and the second body 310g. The third sealing member 390 is used to circumferentially seal the first body 310f and the second body 310g; or, as shown in FIG. Figure 10 As shown, the first body 310f and the second body 310g are spaced apart and arranged in the second shell 320a to form the first chamber 310, and the first body 310f and the second shell 320a are circumferentially sealed by the fourth seal 910, and the second body 310g and the second shell 320a are circumferentially sealed by the fifth seal 920.

[0208] In some embodiments, see Figure 14-16As shown in Figures 21, a portion of the outer wall of the first shell 310a and a portion of the inner wall of the second shell 320a together enclose 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, while the second sealing portion 340b circumferentially surrounds the first shell 310a, and the first sealing portion 340a and the second sealing portion 340b are connected. In this case, the second sealing member 340 not only shapes the second suction channel 321 but also isolates the first chamber 310 from the second chamber 320.

[0209] In an optional embodiment, if Figure 25 As shown, a water leakage gap 312a is provided on the outside of the side wall 310c of the first shell 310a, and the water leakage gap 312a and the inner wall of the second shell 320a form the above-mentioned liquid leakage structure 312; the water leakage gap 312a can be set on the outside of the bottom wall of the first shell 310a, and a sealing strip gap is provided on the second sealing member 340, and the position of the sealing strip gap corresponds to the position of the water leakage gap 312a. By setting the water leakage gap 312a at the sealing gap of the second sealing member 340, when the main body 100 is tilted or lying down, the leakage structure 312 is set on the rear side of the main body 100, so that the water leakage gap 312a can be closer to the rear side and at a lower water level, thereby making it easier for the liquid in the first bin 310 to flow into the second bin 320, preventing the liquid from accumulating in the first bin 310 and posing a safety hazard to the first suction device 400; at the same time, with such a setting, after the first shell 310a is removed from the second shell 320a, the leakage structure 312 only has one water leakage gap 312a left, thereby facilitating the cleaning of the water leakage gap 312a.

[0210] In an optional embodiment, if Figure 26 As shown, the liquid leakage structure 312 is disposed on the bottom wall of the first shell 310 a , and the second sealing member 340 is disposed around the liquid leakage structure 312 .

[0211] In some embodiments, a diameter reduction portion 326 is provided on the inner wall of the second shell 320a along the circumferential direction. The inner diameter of the diameter reduction portion 326 is smaller than the inner diameter of the inner wall above the diameter reduction portion 326, so that the lower portion of the first shell 310a can abut against the diameter reduction portion 326 (e.g., Figure 27 、 28As shown). The lower portion of the first shell 310a abuts against the diameter reduction portion 326, which enables the first shell 310a to be firmly installed inside the second shell 320a. At this time, the lower portion of the first shell 310a can be flexible and can be interference fit with the tightening portion 326; and the rest of the shell 310a can be flexible or hard. At the same time, when the lower portion of the first shell 310a is provided with a second sealing member 340, the second sealing member 340 abuts against the diameter reduction portion (as shown). Figure 29 、 30 As shown), the second seal 340 is deformed, thereby achieving a better seal between the second seal 340 and the second shell 320a, thereby effectively isolating the first chamber 310 and the second chamber 320, so that the first chamber 310 and the second chamber 320 can be relatively independent. In addition, because a gap exists between the lower portion of the first shell 310a and the portion above the diameter reduction portion 326 of the second shell 320a, when the first shell 310a is removed from the second shell 320a, it is only necessary to overcome the initial friction between the diameter reduction portion 326 and the lower portion of the first shell 310a. After the lower portion of the first shell 310a is separated from the diameter reduction portion 326 of the second shell 320a, the lower portion of the first shell 310a and the inner wall of the second shell 320a no longer contact each other during the subsequent removal process, resulting in no frictional resistance, making it more convenient to remove the first shell 310a.

[0212] For example, see 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, wherein the first inner wall 320b and the second inner wall 320c are connected by a diameter reduction portion 326.

[0213] In an alternative embodiment, see Figure 28 、 30 The inner diameter of the tapered portion 326 gradually decreases along the installation direction of the first housing 310a, allowing for smoother installation and removal of the first housing 310a. Furthermore, a second sealing member 340 disposed at the bottom of the first housing 310a provides a better seal, as the bottom of the first housing 310a abuts against the tapered portion 326.

[0214] The embodiment of the present application further provides a seal, which can be applied to the first seal 330 to the fifth seal 920 mentioned above.

[0215] Specifically, such as Figure 28 、 30As shown in FIG. 31 , the seal comprises a seal body 340c and seal lips 340d. The plurality of seal lips 340d extend radially outward from the seal body 340c to abut against the diameter-reduced portion 326. In the cleaning device 10 of the present embodiment, the seal is provided on the first housing 310a.

[0216] In an optional embodiment, the number of sealing lips 340d can be multiple, where multiple means two or more. Multiple sealing lips 340d are simultaneously provided on the sealing body 340c to enhance the sealing effect and achieve multi-layer sealing.

[0217] In an alternative embodiment, see Figure 31 When multiple sealing lips 340d are provided, the length of each sealing lip 340d extending in the direction away from the sealing body 340c gradually decreases from the installation direction of the first shell 310a. Such a setting can make the first shell 310a smoother during the installation process (that is, during the process of the seal and the diameter reduction portion 326 abutting into place).

[0218] In an alternative embodiment, see Figure 31 The thickness of the multiple sealing lips 340d gradually decreases from the installation direction of the first shell 310a, so that the sealing lips 340d that first contact the diameter-reduced portion 326 are easier to deform and then continue to act on the diameter-reduced portion 326, and the sealing lips 340d that finally contact the diameter-reduced portion 326 are relatively less likely to deform, thereby ensuring the seal when in place, facilitating the installation of the first shell 310a, making the installation of the first shell 310a smoother, and also ensuring the sealing effect.

[0219] In an alternative embodiment, see Figure 31 The sealing lip 340d is tilted on the sealing body 340c, and its tilting direction is toward the disassembly direction of the first shell 310a, so that the installation of the first shell 310a is smoother and facilitates the installation of the first shell 310a.

[0220] In an alternative embodiment, see Figure 31 The thickness of the sealing lip 340d gradually decreases in the direction from the sealing body 340c to the direction away from the sealing body 340c. Such a setting can improve the strength of the root of the sealing lip 340d and increase the flexibility of the end, so that the end can be better deformed and sealed.

[0221] Illustratively, the cross-section of each sealing lip 340d is triangular or trapezoidal, which facilitates the installation of the first shell 310a while ensuring the sealing effect.

[0222] In an optional embodiment, the outward extension length of the sealing lip 340d is greater than the gap between the first shell 310a and the second inner wall 320c of the second shell 320a, and smaller than the gap between the first shell 310a and the first inner wall 320b of the second shell 320a, that is, after the first shell 310a is installed in place, the sealing lip 340d can abut and seal with the second inner wall 320c. When the first shell 310a is not installed in place or removed, the sealing lip 340d is located inside the first inner wall 320b and does not contact the first inner wall 320b. A gap is formed between the sealing lip 340d and the first inner wall 320b, thereby avoiding additional friction resistance during the installation and removal process, making the installation and disassembly of the first shell 310a smoother. At the same time, if the liquid in the first shell 310a or the liquid between the first shell 310a and the second shell 320 can flow into the second compartment 320 through the above-mentioned gap during the removal of the first shell 310a, the liquid can be prevented from being taken out when the first shell 310a is removed, affecting the user experience.

[0223] The second suction device 500 described in the above embodiment is a gas suction device. However, since gas suction devices also carry a certain risk of water ingress, to further address this issue, a gas-liquid separation design is implemented in the second suction channel 321, such as the aforementioned baffle structure. In other embodiments of the present application, the second suction device 500 may also be a liquid suction device. Liquid suction devices inherently allow liquid to pass through, thus eliminating the need to address water ingress.

[0224] In some embodiments, see Figures 32-34 The second suction device 500 includes a liquid suction device, which is located in the second suction channel 321; at this time, the second suction channel 321 and the channel of the liquid leakage structure 312 are the same channel, wherein the second suction channel 321 includes a liquid inlet and a liquid outlet, the liquid inlet is connected to the liquid suction end of the liquid suction device, and the liquid outlet is connected to the liquid outlet end of the liquid suction device. The liquid suction device is used to suck and drive the sewage entering the first bin 310 into the second bin 320. This setting does not have to worry about the problem of water ingress and damage to the liquid suction device; in order to make the liquid suction device work better, a filter 350 can be further set in the first bin 310 to separate the dirt sucked into the first bin 310 from the outside, and then the separated sewage only needs to be driven into the second bin 320 through the liquid suction device. At the same time, this setting can effectively prevent the liquid in the second bin 320 from flowing back into the first bin 310 regardless of whether the cleaning device 10 is in a tilted, lying down, shaking or upright state; it can also ensure that the liquid in the first bin 310 is discharged in time to prevent water from entering the first suction device 400.

[0225] In the embodiment of the present application, when the first shell 310a is partially or completely disposed in the second shell 320, that is, when the first shell 310a is nested in the second shell 320, especially when an interference fit is provided between the first shell 310a and the second shell 320 to ensure stable installation, there is a large friction force during the removal or installation of the first shell 310a, or the first shell 310a is not convenient for the user to pick up, resulting in a user-unfriendly user experience when the first shell 310a and the second shell 320 are disassembled. Therefore, the embodiment of the present application proposes the following solution:

[0226] In some embodiments, as Figures 35-41 The first shell 310a and the second shell 320a are detachably connected, and a handle 313 is installed on the first shell 310a so that the user can hold the handle 313 to pull the first shell 310a out of the second shell 320a.

[0227] In an alternative embodiment, see Figure 35 、 36 The handle 313 is rotatably disposed on the first housing 310a, wherein the handle 313 has a first position (eg, Figure 35 ) and rotated to a second position for the user to take (as shown Figure 36 When the handle 313 is in the first position, the handle 313 can be snapped onto the circumference 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 to the end surface 310m of the first shell 310a, allowing the user to grasp and apply force to remove the first shell 310a from the second shell 320a.

[0228] In an alternative embodiment, see Figure 37 When an opening 325 connected to the first compartment 310 is provided on the side of the first shell 310a, the handle 313 can be rotated from a first position to a second position along the side of the first shell 310a where the opening 325 is provided, so that the user's hand can hold the handle 313 and use the fingers to abut the upper end of the first shell 310a, thereby being able to stably pick up the first shell 310a and reducing the possibility of the stored items in the first compartment 310 falling out of the opening 325.

[0229] In an alternative embodiment, see Figure 37The handle 313 is arranged at an angle to the end surface 310m of the first housing 310a. Specifically, when the handle 313 is in the second position, the angle between the handle 313 and the front end surface 310h of the first housing 310a is greater than or equal to 90 degrees. This arrangement allows the user to more stably pick up the first housing 310a when emptying waste. The end surface 310m of the first housing 310a is divided into a front end surface 310h and a rear end surface 310k by the rotation axis 313d of the handle 313. The front end surface 310h is the end surface portion in the rotation direction when the handle 313 rotates from the first position to the second position, and the rear end surface 310k is the end surface portion in the rotation direction when the handle 313 rotates from the first position to the second position.

[0230] In an alternative embodiment, see Figures 38-41 A position prompting device 314 is provided on the first shell 310a and / or the handle 313, so that when the handle 313 is rotated to the first position and / or the second position relative to the first shell 310a, the position prompting device 314 can generate a position prompt to prompt the user that the handle 313 has been rotated to a specific position.

[0231] In an optional embodiment, the in-place prompting device 314 may be provided only at the first position or the second position, or may be provided at both the first position and the second position.

[0232] For example, when a user rotates the handle 313, they apply force to the handle 313. The in-position prompting device 314 can be a structure that can generate varying resistance to the handle 313 during the rotation of the handle 313. The resistance of the handle 313 at the first and second positions is different from that at other positions. This allows the user to clearly perceive the difference in resistance and identify different positions during the rotation of the handle 313. In other embodiments, the resistance at the first and second positions 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, the resistance is transmitted to the user, thereby achieving the purpose of prompting the user to the in-position.

[0233] It should be noted that the in-place prompting device 314 can be implemented by a mechanical structure or by an in-place detection device. Specifically, the in-place prompting device 314 includes: an in-place protrusion 314a, and an in-place groove 314b adapted to the in-place protrusion 314a. The in-place protrusion 314a and the in-place groove 314b are respectively arranged on the handle 313 and the first shell 310a. The in-place protrusion 134a can be arranged on the first shell 310a, or the 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 passes over the in-place protrusion 314a, which causes the resistance of the handle 313 to change, thereby providing a in-place prompt to the user. The in-place prompting device 314 can also be a magnetic component, such as a matching magnetic component is arranged on the handle 313 and the first shell 310a and / or the second shell 320, and the in-place reminder function is formed through the connection between the two magnetic components. Furthermore, the magnetic element can be respectively arranged at the first position and / or the second position.

[0234] In an optional embodiment, the handle 313 is disposed on the first housing 310a via damped rotation, wherein the rotational resistance of the handle 313 in the first position and / or the second position is greater than the rotational resistance when the handle 313 is between the first and second positions. The damping sensation can provide a sense of position for the user, and when the handle 313 is in the second position, the damping between it and the first housing 310a can provide a more stable grip of the first housing 310a with the handle 313 when the user is emptying the trash.

[0235] It should be noted that the rotational 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 by placing a rubber ring on the rotating shaft 313d and then installing it into the handle 313 or the first shell 310a, so that the handle 313 has a damping feeling during the rotation process. This application is not limited to this.

[0236] In an optional embodiment, if Figures 38-40 As shown, the first housing 310a has a limiting portion 314c, which is used to prevent the handle 313 from continuing to rotate forward. The handle 313 includes a handle 313e, a rotating shaft 313d, and a stopper 313f. The handle 313e and the stopper 313f are respectively provided on opposite sides of the rotating shaft 313d. The handle 313e is used to provide a grip for the user. When the handle 313 rotates from the first position to the second position, the limiting portion 314c is provided in front of the handle 313e (not shown) and / or behind the stopper 313f (as shown). Figure 38 、 40 shown).

[0237] The limiting portion 314c can be set to allow the handle 313 to stay in the second position, so that it is convenient for the user to apply force to the handle 313 to lift the first shell 310a from the second shell 320a, allowing the user to be more stable when cleaning the garbage in the first shell 310a.

[0238] In an optional embodiment, if Figure 35 、 36 As shown, a butt-jointed top portion 313f is provided at the rotating shaft 313d of the handle 313, and the second shell 320a includes a first butt-jointed surface 320d. During the process of the handle 313 rotating from the first position to the second position, the butt-jointed top portion 313f rotates toward the first butt-jointed surface 320d and finally butts against the first butt-jointed surface 320d. At this time, the handle 313 continues to be rotated, and the butt-jointed top portion 313f of the handle 313 acts on the first butt-jointed surface 320d, and an upward thrust is applied to the rotating shaft 313d of the handle 313 with the contact point between the butt-jointed top portion 313f and the first butt-jointed surface 320d as a fulcrum, thereby pushing the rotating shaft 313d of the handle 313 away from the first butt-jointed surface 320d, and finally driving the first shell 310a to separate from the second shell 320. In some cases, the first shell 310a and the second shell 320a are nested, and a seal is provided between the first shell 310a and the second shell 320a. Due to the sealing effect, the resistance is greatest when just taken out. Through the principle of force-saving lever, the strong arm of the handle 313 is used to drive the top 313f to pry out the first shell 310a in place a short distance, thereby overcoming the greater resistance when just taken out, making the removal process of the first shell 310a smoother.

[0239] In an optional embodiment, if Figure 35 、 36As shown, the second housing 320a includes a second abutting surface 320e. After the first housing 310a is installed in the second housing 320a, as the handle 313 rotates from the second position to the first position, the handle 313 drives the abutting top portion 313f to rotate toward the second abutting surface 320e and contact the second abutting surface 320e. The handle 313 then continues to rotate, and the abutting top portion 313f and the second abutting surface 320e interact with each other. The handle 313 uses the contact point between the abutting top portion 313f and the second abutting surface 320e as a fulcrum to apply downward pressure to the rotating shaft 313d of the handle 313, thereby pressing the first housing 310a downward into the installation position of the second housing 320a. Throughout this process, the long lever arm of the handle 313 drives the abutting top portion 313f to press the first housing 310a, which is not installed in the second housing 320a, into the second housing 320a through the principle of a force-saving lever. At the same time, in some cases, there is a seal between the first shell 310a and the second shell 320. By utilizing the cooperation between the abutting top 313f and the second abutting surface 320e of the handle 313, the first shell 310a can accurately install the second shell 320a in place, thereby establishing a better seal between the first shell 310a and the second shell 320a.

[0240] In an optional embodiment, the second shell 320a is provided with a receiving groove 315 for accommodating the top portion 313f of the handle 313, the bottom wall of the receiving groove 315 forms a first abutting surface 320d, and the top wall of the receiving groove 315 forms a second abutting surface 320e, wherein the bottom wall and the top wall can be arranged relative to each other or in a state of being approximately relative to each other.

[0241] In an alternative embodiment, reference Figure 36 The top portion 313f includes a top surface 3133f and a first surface 3131f and a second surface 3132f located on both sides of the top surface 3133f. The distance from the top surface 3133f to the center of the rotation axis of the handle 313e is greater than the distance from the first surface 3131f to the center of the rotation axis 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 the first abutting surface 320d; such a setting enables the handle 313 to rotate from the first position to the second position, and the surface of the abutting top 313f facing the first abutting surface 320d transitions from the first surface 3131f to the abutting top surface 3133f. At this time, the gap between the abutting top 313f and the first abutting surface 320d gradually decreases until the abutting top surface 3133f contacts the first abutting surface 320d. As the handle 313 rotates, the abutting top surface 3133f further abuts the first abutting surface 320d to separate the first shell 310a from the second shell 320.

[0242] In an optional embodiment, when the handle 313 is in the second position, a gap exists between the second surface 3132f and the second abutting surface 320e; when the handle 313 is in the first position, the second surface 3132f abuts the second abutting surface 320e. This configuration allows the gap between the second abutting surface 320e and the abutting top portion 313f to gradually decrease as the handle 313 rotates from the second position to the first position. That is, as the handle 313 rotates, the second surface 3132f gradually approaches the second abutting surface 320e until the second surface 3132f contacts the second abutting surface 320e. Furthermore, as the handle 313 continues to rotate, the second surface 3132f abuts the second abutting surface 320e, causing the second abutting top portion 3133f to exert a downward force on the second surface 3132f, thereby pressing the first housing 310a into the second housing 320.

[0243] In an optional embodiment, the abutting top portion 313f is cam-shaped or long-arm-shaped; the protruding surface of the cam corresponds to the abutting top surface 3133f; and the surface of one end of the long arm corresponds to the abutting top surface 3133f.

[0244] In an optional embodiment, the first housing 310a and the second housing 320a have an interference fit. This interference fit can provide a more stable installation of the first housing 310a and the second housing 320. This interference fit can be a direct interference fit between the first housing 310a and the second housing 320, or an indirect fit between the first housing 310a and the second housing 320 through other components, such as seals and elastic members. Furthermore, the interference fit can cause significant friction during installation and removal of the first housing 310a from the second housing 320, thereby adversely affecting the user experience or causing the first housing 310a to be improperly installed.

[0245] Therefore, to facilitate removal of the first shell 310a from the second shell 320, the handle 313 is provided with an abutment portion 313f at its pivoting connection. The abutment portion 313f includes an abutment surface 3133f. The distance between the abutment surface 3133f and the center of the rotation axis of the handle 313e is greater than the travel of the interference fit between the first shell 310a and the second shell 320a in the removal direction. The interference fit travel here refers to the displacement from the starting point to the point where the interference fit is released during the process of removing the first shell 310a from the second shell 320. The inner diameter of the second shell 320 varies, with an interference fit formed at the smaller inner diameter and released at the larger inner diameter. The distance from the abutting surface 3133f to the center of the rotating shaft is set in this way, so that when taking the first shell 310a from the second shell 320, the handle 313 is rotated upward, and the abutting surface 3133f of the abutting top 313f will gradually abut the second shell 320, thereby forming a displacement between the first shell 310a and the second shell 320. The distance of this displacement is the distance that the handle 313 can assist in taking out the first shell 310a. This distance only needs to be larger than the interference fit distance that the first shell 310a and the second shell 320 need to go through during the removal process. Then, the handle 313 can use its leverage to help the user overcome the problem of difficulty in removal caused by the interference fit distance, so as to improve the user experience.

[0246] In an optional embodiment, a seal is provided between the first housing 310a and the second housing 320 to isolate the first chamber 310 from the second chamber 320 or to form a suction channel for the second suction device 500. Because the presence of the seal results in greater friction when removing or installing the first housing 310a from the second housing 320, the leverage of the handle 313 can be utilized to save user effort and enhance the user experience.

[0247] In an optional embodiment, a tapered portion 326 is provided between the first housing 310a and the second housing 320. The tapered portion 326 is primarily intended to reduce the gap between the first housing 310a and the second housing 320, thereby ensuring a stable fit between the first housing 310a and the second housing 320. The tapered portion 326 can also cooperate with a seal, thereby further stabilizing the gap between the first housing 310a and the second housing 320 and improving the sealing capability.

[0248] In order to prevent the user from accidentally spilling the dirt inside the first shell 310a when taking out the first shell 310a, the following design is proposed:

[0249] like Figure 42As shown, for the embodiment in which the first shell 310a is nested in the second shell 320a, in order to facilitate the removal of the first shell 310a from the second shell 320a, the outer wall of the second shell 320a can be provided with a handle 327, and the side wall 310c of the first shell 310a has an opening 325, which is arranged toward the handle 327. The handle 327 can be used by the user to hold the water tank 300. The opening 325 is arranged toward the handle 327 to facilitate the user to hold the sewage tank in one hand (such as Figure 42 The other hand (such as the right hand) holds the buckle 327 of the second shell 320a, and the other hand (such as Figure 42 In the figure, the left hand holds the first shell 310a and takes the first shell 310a out of the second shell 320a in a roughly horizontal direction. At this time, the opening of the first bin 310 is roughly facing upward, and the dirt in the first bin 310 is blocked by the non-open side wall 310c of the first shell 310a, which can effectively prevent the dirt in the first bin 310 from falling.

[0250] 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. 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 clogging the sewer; if the solid-liquid mixture is poured into a trash can, there is a risk of the trash bag being damaged and leaking. To address the above specific technical problems, the embodiment of the present application proposes the following solutions:

[0251] In an optional embodiment, the cleaning device 10 further includes a sewage suction pipe 112, and the outlet 112c of the sewage suction pipe is connected to the first bin 310. Figure 4 、 5 When the two are independent of each other, the outlet 112c of the sewage suction pipe is directly connected to the first chamber 310. Figure 6-10 As shown in Figures 44, when the first housing 310a is at least partially nested in the second housing 320, the sewage suction pipe 112 includes a sewage suction pipe 112a and a sewage inlet pipe 112b. The sewage suction pipe 112a is arranged outside the chassis 200 and main body 100 of the cleaning device 10, that is, the first chamber 310 and the second chamber 320, while the sewage inlet pipe 112b is arranged inside the water tank. The water outlet of the sewage inlet pipe 112b is the outlet 112c of the sewage suction pipe, which is used to drive external sewage into the first chamber 310. The first suction device 400 can sequentially suck air through the first suction channel 311, the first chamber 310, and the first suction channel 311 to form a negative pressure, thereby sucking external sewage into the first chamber 310.

[0252] In some embodiments, for example, Figure 18 、 24As shown in Figures 43, a filter screen 350 is provided in the first bin 310, and the filter screen 350 is arranged between the liquid leakage structure 312 of the first bin 310 and the second bin 320 and the outlet 112c of the sewage suction pipe; wherein, the first bin 310 is located on one side of the outlet end to form a solid waste chamber 316 for accommodating solid waste, so that the first suction device 400 sucks external dirt into the first bin 310 through the sewage suction pipe 112, and then the first bin 310 can accumulate the solid waste in the dirt in the solid waste chamber 316, while the liquid flows into the second bin 320 through the liquid leakage structure 312 or is sucked into the second bin 320 by the second suction device 500 to achieve solid-liquid separation.

[0253] Setting up the filter 350 can separate the dirt generated during the cleaning process, separate it into solid waste and store it in the first bin 310, and separate it into liquid and store it in the second bin 320. Such a setting can facilitate users to separate and process different types of dirt, so as to reduce the probability of bad user experience such as clogging the sewer or spilling liquid on the ground. At this time, driving the separated liquid into the second bin 320 through 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 and reduce the probability of water or water vapor in the first bin 310 entering the first suction device 400; at the same time, it can also improve the dryness of solid and liquid waste, so as to reduce the bad experience of users caused by dripping when handling solid waste. In an optional embodiment, such as Figure 18 、 24 As shown, the filter 350 is located at the bottom of the first bin 310, that is, the filter 350 is arranged above the bottom wall of the first shell 310a, and the leakage structure is arranged below the filter 350. In this way, the dirt can also be separated into solid and liquid under the action of gravity. A solid waste chamber 316 is formed above the filter 350 for accumulating solid waste, and a leakage structure 312 is formed below the filter 350 to allow the liquid filtered from the dirt to flow to the second bin 320.

[0254] In some embodiments, as Figure 18 、 24 As shown in Figures 43 and 44, the filter screen 350 is rotatably disposed in the first bin 310 so that when cleaning the filter screen 350 or removing solid waste from the solid waste chamber 316, the filter screen 350 can be rotated from the inside of the first bin 310 to the outside of the first bin 310. When dumping waste, after tilting the first housing 310a to a certain angle, the filter screen 350 will rotate due to gravity and carry the waste above the filter screen 350 out of the solid waste bin, preventing the 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 to remove them. This arrangement facilitates the disposal of waste in the solid waste bin.

[0255] In some embodiments, as shown in Figures 24 , 43 , and 45 , the filter 350 is rotatably mounted in the first chamber 310 via a rotating pair 351 .

[0256] Exemplarily, the filter 350 is rotatably mounted within the first compartment 310 via a pivoting pair 351, wherein the pivoting axis of the pivoting pair 351 is arranged substantially horizontally or vertically. The terms "substantially horizontal" and "substantially vertical" refer to the fact that when the main body 100 of the cleaning device 10 is in a vertical position, the pivoting axis of the pivoting pair 351 is within a 10° range of either horizontal or vertical.

[0257] In an optional embodiment, the side of the first chamber 310 is an opening 325, and a rotating mounting portion 353 is provided below the opening 325 of the first chamber 310. The rotating pair 351 is installed on the rotating mounting portion 353, and the filter 350 can be turned outward around the lower side at the opening 325 of the first chamber 310 to open the first chamber 310. Figure 43 shown.

[0258] In an optional embodiment, if Figure 24 As shown, the side of the first bin 310 is an opening 325, and a rotating mounting portion 353 is provided on one side of the opening 325 of the solid waste chamber 316. The rotating pair 351 is installed on the rotating mounting portion 353, and the filter 350 can flip around the left and right sides at the opening 325 of the first bin 310 to open the first bin 310.

[0259] In an optional embodiment, if Figure 24 The filter 350 includes a first filter 350a and a second filter 350b that can rotate toward each other, wherein the side of the first bin 310 is an opening 325, the first filter 350a is rotatably installed on the left side of the solid waste chamber 316, and the second filter 350b is rotatably installed on the right side of the solid waste chamber 316, and the first filter 350a and the second filter 350b are respectively flipped around the left and right sides of the opening 325 on the side of the first bin 310 to open the first bin 310.

[0260] In an optional embodiment, if Figure 24The filter 350 includes a filter base plate 350c and a filter side plate 350d connected to the edge of the filter base plate 350c. The filter holes 352 of the filter 350 are provided on the filter base plate 350c and / or the filter side plate 350d. The filter side plate 350d can be provided to enclose the garbage on the filter base plate 350c after the first housing 310a is removed, preventing the garbage on the filter base plate 350c from leaking out from the edge. The filter side plate 350d also increases the effective area of ​​the filter 350, thereby improving the efficiency of solid-liquid separation of the waste in the first chamber 310 and allowing the wastewater in the first chamber 310 to enter the second chamber 320 more quickly through the liquid leakage structure 312. This helps reduce the risk of liquid intrusion into the first suction device 400.

[0261] Optionally, the height of the filter side plate 350d is adapted to the height of the first bin 310 so as to seal the side of the first bin 310 and further prevent the garbage in the first bin 310 from falling out.

[0262] In an optional embodiment, the filter 350 is detachably connected to the first bin 310 . When dumping garbage, the filter 350 and the garbage can be removed together, and the filter 350 can be dumped separately and cleaned, which facilitates the replacement or cleaning of the filter 350 .

[0263] Optionally, a filter taking portion may be provided on the filter 350 for taking the filter 350 out of the first compartment 310 , so as to facilitate taking and placing the filter 350 .

[0264] In an optional embodiment, the filter screen 350 is located at the lower end of the first bin 310 , and can separate the solid and liquid in the first bin 310 at the bottom of the first bin 310 , maximize the utilization of the volume of the first bin 310 , and maximize the solid waste chamber 316 in the first bin 310 .

[0265] In an optional embodiment, if Figure 46 As shown, the filter screen 350 has a three-dimensional structure, such as a columnar shape; and the filter screen 350 is arranged around the leakage structure 312. The filter screen 350 is arranged along the height direction, which increases the area of ​​the filter screen 350 in the height direction. As the solid waste accumulates, the filter screen 350 is not easy to be blocked, and the solid waste in the solid waste chamber 316 can ensure a high filtration efficiency at any height.

[0266] In an optional embodiment, the filter 350 is a disposable box that can be placed in the first compartment 310. The box is shaped to match the first compartment 310. The box has a bottom wall and side walls, with the bottom wall having filter holes 352. The bottom wall of the box matches the bottom wall of the first compartment 310. The side walls of the box match the inner side walls of the first shell 310a and / or the second shell 320a. The side walls of the box can be used to prevent garbage from falling when removing the filter 350. The side walls of the box can also be provided with filter holes 352. The box can also be arranged in the same manner as the filter design described above. Setting the filter as a disposable filter can further reduce the difficulty of garbage disposal for users.

[0267] The first suction device 400 in the cleaning device 10 is often a device capable of generating negative pressure, such as a fan. The first suction device 400 is connected to the first chamber 310 via the first suction channel 311, and is used to provide power to suck dirt generated during the operation of the cleaning device 10 back into the first chamber 310. However, the dirt usually contains water or water vapor, which can easily enter the first suction device 400 through the first suction channel 311, thereby causing damage to the first suction device 400 or liquid leakage. Therefore, the embodiment of the present application has the following improvements:

[0268] In an optional embodiment, if Figures 47-49 As shown, the first housing 310a may be provided with an air inlet 317, which is used to connect the first suction device 400 to the first bin 310. The channel of the air inlet 317 constitutes a portion of the first suction channel 311. The first suction device 400 provides suction power to the first bin 310 through the air inlet 317, so that external dirt can be sucked into the first bin 310.

[0269] For example, Figure 47 、 48 As shown, the first shell 310a includes a top wall 310b and a side wall 310c, wherein the air intake 317 is provided on the top wall 310b, and there is a distance between the edge of the air intake 317 and the side wall 310c. In the process of the first suction device 400 sucking the first bin 310 through the air intake 317, the water on the side wall 310c may move upward along the side wall 310c and then enter the first suction device 400 with the suction force of 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 intake 317 and the side wall 310c, so as to prevent the water from directly entering the air intake 317 upward along the side wall 310c, thereby reducing the probability of liquid entering the first suction device 400 directly from the air intake 317.

[0270] In an optional embodiment, a water retaining structure 318 is provided on the top wall 310 b of the first shell 310 a , and the water retaining structure 318 is used to prevent liquid from entering the air inlet 317 .

[0271] For example, Figure 46 、 47 The water retaining structure 318 may include a first water retaining portion 318a located at the rear side of the air inlet 317 to block the liquid in the first chamber 310 from oscillating from the rear side to the air inlet 317. In particular, when the main body 100 is tilted or lying down, the liquid flows to the rear side, resulting in a higher base water level. When the liquid further oscillates upward with the oscillation, it can be blocked by the first water retaining portion 318a located at the rear side of the air inlet 317. Optionally, the first water retaining portion 318a is arranged in the left-right direction.

[0272] In an optional embodiment, if Figure 47 The water retaining structure 318 includes a second water retaining portion 318b, which is located between the air intake port 317 and the side wall 310c of the first shell 310a. A gap exists between the second water retaining portion 318b and the side wall 310c of the first shell 310a to block the wall-mounted liquid on the top wall 310b and the side wall 310c. Exemplarily, the second water retaining portion 318b is a wall surface extending downward from the top wall 310b. The wall surface can be a flat surface or an arcuate surface. It is arranged around the air intake port 317. When the air intake port 317 sucks the first chamber 310, water droplets or water films may be sucked upward along the side wall 310c due to the surface tension of the water. The second water retaining portion 318b can prevent these water droplets or water films from continuing to flow along the top wall 310b and into the air intake port 317. In an optional embodiment, the outlet 112c of the sewage suction pipe is connected to the first chamber 310, and the water retaining structure 318 includes a third water retaining portion 318c, which is located between the air inlet 317 and the outlet 112c of the sewage suction pipe, and is used to prevent the liquid at the outlet 112c of the sewage suction pipe from being directly sucked into the air inlet 317. Figure 50 As shown, the third water retaining portion 318c is an annular enclosure provided on the top of the first bin 310, and its lower edge is located below the outlet 112c of the sewage suction pipe.

[0273] It should be noted that the first water retaining portion 318a, the second water retaining portion 318b and the third water retaining portion 318c can be connected to each other to form a whole, and the whole can be arranged around at least a portion of the air inlet 317. For example, the whole is cylindrical.

[0274] In some embodiments, as Figure 48As shown, the water retaining portion 318 further includes a fourth water retaining portion 318d, which is disposed between the air inlet 317 and the water retaining portion 318c to prevent wall-mounted water in the water retaining portion 318c from entering the air inlet 317. The fourth water retaining portion 318d can form a whole with the first water retaining portion 318a and the second water retaining portion 318b, and the whole can be disposed around at least a portion of the air inlet 317. Exemplarily, the whole is cylindrical.

[0275] The purpose of the water retaining portion 318 is mainly to prevent liquid from entering the air intake port 317 from the first chamber 310. As for its structural form, this application is not limited. As long as it can prevent liquid from entering the air intake port 317 from the first chamber 310, it is the above-mentioned structure. In some embodiments, only one or two of the first water retaining portion 318a, the second water retaining portion 318b, the third water retaining portion 318c, and the fourth water retaining portion 318d can be provided.

[0276] In an alternative embodiment, see Figure 46 、 47 As shown, the air intake 317 is located on the front side of the first bin 310 to reduce the probability of liquid flowing from the first bin 310 into the air intake 317 when the main body 100 is in a tilted or lying state. When the main body 100 is lying down, the air intake 317 located on the front side can be located above the first bin 310 in the lying state, far away from the liquid level in this state, preventing liquid from flowing into the air intake 317 in the lying state of the first bin 310.

[0277] In an optional embodiment, there are two air inlets 317, which are respectively located on the left and right sides of the outlet 112c of the sewage suction pipe. The arrangement in sequence makes the space in the first bin 310 more compact, and the sewage suction pipe 112 and the air inlet 317 can be set on the same side of the first bin 310 (that is, both are located on the front side of the first bin 310); when the sewage suction pipe 112 and the air inlet 317 are both set on the front side of the first bin 310, when the main body 100 lies down, the suction pipe 112 and the air inlet 317 are both located on the front side of the first bin 310. When cleaning, the outlet 112c of the sewage suction pipe and the air intake 317 can both be located on the upper side of the first bin 310, far away from the liquid level in the first bin 310 at this time, preventing the liquid in the first bin 310 from flowing back into the air intake 317, or flowing back to the surface to be cleaned along the outlet 112c of the sewage suction pipe; further, a third water retaining portion 318c can be set between the sewage suction pipe 112 and the air intake 317 to prevent the liquid from being directly drawn into the air intake 317 from the outlet 112c of the sewage suction pipe.

[0278] In an optional embodiment, the outlet 112c of the sewage suction pipe is located on the front side of the first bin 310. When the main body 100 is in a tilted or lying state, the outlet 112c of the sewage suction pipe is located on the upper side of the first bin 310, which is far away from the liquid water level in the first bin 310 at this time, and can prevent the liquid in the first bin 310 from flowing back to the ground along the outlet 112c of the sewage suction pipe.

[0279] In an optional embodiment, the outlet 112c of the sewage suction pipe is located above the lower edge of the third water retaining portion 318c, and can change the direction of the fluid (including water flow and air flow) by 180 degrees, from upward flow to downward flow, and then after being sucked through the upper air intake 317, it changes from downward flow to upward flow. Through two changes of direction, the liquid mixed in the air flow is thrown out, thereby assisting the separation of liquid and gas in the first bin 310.

[0280] It is understood that the third water retaining portion 318c can be in the form of a ring, a rectangular frame, or a polygonal frame, and is disposed around the outlet 112c of the sewage suction pipe. The third water retaining portion 318c can also be a baffle. In some embodiments, there can be at least two third water retaining portions 318c, and similarly, the number of first water retaining portions 318a and second water retaining portions 318b is not limited.

[0281] In an optional embodiment, if Figure 50 The distance between the left and right sides of the third water retaining portion 318c and the sewage suction pipe 112 is smaller than the distance between the rear side of the third water retaining portion 318c and the sewage suction pipe 112, that is, the liquid and airflow coming out of the sewage suction pipe 112 will flow downward through the gap between the third water retaining portion 318c and the sewage suction pipe 112. The larger gap between the rear side of the third water retaining portion 318c and the sewage suction pipe 112 is beneficial to reducing the speed of the liquid and airflow flowing out through this side, thereby preventing the water and liquid flowing out of this side from causing a greater impact on the leakage structure 312. Because the greater the impact, the more impact it will have on the liquid accumulated in the leakage structure 312, the liquid accumulated here that has not yet entered the second chamber 320 may be dispersed under the large impact, especially when most of the liquid entering from the sewage suction pipe 112 is gas, which will affect the liquid from converging to the leakage structure 312, thereby affecting the normal operation of the leakage structure 312; the smaller gaps between the left and right sides of the third water retaining part 318c and the sewage suction pipe 112 are conducive to increasing the speed of the liquid and airflow flowing out on both sides, thereby improving the separation effect of the liquid and airflow flowing out from both sides.

[0282] In some embodiments, the front side height of the outlet 112c of the sewage suction pipe is higher than the rear side height (e.g. Figure 49As shown), such an arrangement can drain the dirt coming out of the sewage suction pipe 112 to the rear side, and since the sewage suction pipe 112 is arranged on the front side, the dirt flowing out of the outlet 112c of the sewage suction pipe can enter the larger space on the rear side of the sewage suction pipe 112, preventing the outlet 112c of the sewage suction pipe from being blocked.

[0283] In some embodiments, as Figure 7 As shown, the content detection component 360 of the cleaning equipment 10, the control device 600 is connected to the content detection component 360, and the content detection component 360 is arranged in the first warehouse 310 and / or the second warehouse 320, and is used to detect the content information and dirtiness in the first warehouse 310 and / or the second warehouse 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 dirtiness information and content information detected by the content detection component 360.

[0284] For example, a filter screen 352 may be provided in the first bin 310 to form a solid-liquid separation bin, and the content information may indicate the capacity of solid waste.

[0285] For example, the first detection assembly 361 in the first chamber 310 is disposed above the first chamber 310 ;

[0286] For example, the first detection component 361 in the first bin 310 is arranged on the rear side above the first bin 310. Such an arrangement allows the cleaning device to be in a lying state. If liquid triggers the first detection component 361, it means that the first suction device 400 is at risk of liquid ingress.

[0287] For example, the first detection assembly 361 in the first chamber 31 is disposed below the air inlet 317 , so that it can be triggered before the contents in the first chamber 310 clog the air inlet 317 .

[0288] Furthermore, it may also include a prompt device (not shown), which is electrically connected to the content detection component 360, so that when the amount of dirt in the first bin 310 and / or the second bin 320 reaches a preset value or is triggered, the prompt 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 backflow of liquid in the first bin 310 and the second bin 320.

[0289] For example, the control device 600 is connected to the first detection assembly 361 and 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 to reduce or shut down 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.

[0290] At the same time, when the amount of dirt in the first bin 310 is large (for example, there is a lot of solid waste in the first bin 310), the liquid in the first bin 310 will not easily enter the second bin 320 to a certain extent. Therefore, in this scenario, the operating parameters of the second suction device 500 can be adjusted through the control device 600 to increase the suction force of the second suction device 500, so that the second suction device 500 provides a greater suction force to be able to more fully suck the liquid in the first bin 310 to the second bin 320.

[0291] It should be noted that the first detection component 361 detects the amount of dirt in the first bin 310, including the detection of solids, viscous substances or liquids in the first bin 310, and the specific detection methods adopted include but are not limited to the detection of dirt height, the detection of dirt weight, and even the direct visual detection of the amount of dirt, which is not limited in this application.

[0292] In one embodiment, the cleaning device includes a second detection component 362, which detects information about the contents of the second chamber. For example, when the amount of dirt in the second chamber 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 chamber 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 chamber 320 reaches a preset amount, the control device 600 can also reduce or turn off the suction force of the first suction device 400, thereby preventing the liquid in the second chamber 320 from continuing to increase.

[0293] Exemplarily, 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, and 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 external liquid can enter the first chamber 310 and the liquid in the first chamber 310 can enter the second chamber 320. 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 chamber 310 and / or the second chamber 320. In particular, when the amount of liquid dirt is large, the suction device can be turned off in time or the suction force of the suction device can be reduced (the greater the suction force, the greater the operating power required, 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.

[0294] On the other hand, because the operating parameters of the second suction device 500 can be flexibly adjusted based on the amount of dirt in the first bin 310, the operating power of the second suction device 500 can be reduced when the amount of dirt in the first bin 310 is low, and the operating power of the second suction device 500 can be increased when the amount of dirt in the first bin 310 is high. By matching the amount of dirt in the first bin 310 with the operating parameters of the second suction device 500, dynamic adjustment of the operating parameters of the second suction device 500 is achieved. This avoids the problem of the second suction device 500 always operating at a high power and causing high operating noise, reduces the impact of operating noise on the user experience, and effectively improves the user experience.

[0295] In other embodiments, the rear side height of the outlet 112c of the sewage suction pipe is higher than the front side height. When the main body 100 is tilted or lying down, the rear side of the outlet 112c of the sewage suction pipe is higher than the front side, which can form a barrier from the rear side to the front at the outlet, and can effectively reduce the risk of liquid in the first bin 310 flowing back from the front side of the outlet of the sewage suction pipe 112 which is closer to the liquid level when the main body 100 is in a tilted or lying down state.

[0296] It can be understood that the outlet 112 c of the sewage suction pipe is arranged at an angle, which can redirect the gas or liquid flowing out of the outlet of the sewage suction pipe 112 and prevent the gas or liquid from directly impacting the top plate of the first chamber 310 .

[0297] In the embodiment of the present application, when the first shell 310a is nested in the second shell 320, since the first chamber 310 and the second chamber 320 need to be relatively independent, thereby ensuring that the suction force of the gas suction device acts on the liquid leakage structure as much as possible, the gap between the first shell 310a and the second shell 320 needs to be reduced as much as possible. Since the sewage suction pipe 112 for recovering dirt generated by the cleaning device passes through the second shell 320 and then connects to the first chamber 310, and in order to facilitate the disposal of garbage in the first chamber 310, the first shell 310a needs to be detachable. Therefore, a gap is formed between the sewage suction pipe 112 and the first shell 310a. To reduce the impact of this gap, the embodiment of the present application proposes the following solution:

[0298] In an optional embodiment, if Figures 44-53 As shown, the sewage suction pipe 112 also includes a sewage inlet pipe 112b provided in the second shell 320a and a sewage extraction pipe 112a connected to the sewage inlet pipe 112b, wherein the sewage extraction pipe 112a is used to draw dirt and sewage on the ground into the sewage inlet pipe 112b, wherein the sewage inlet pipe 112b is connected to the first bin 310, and a seal is provided at the connection between the sewage inlet pipe 112b and the first shell 310a, which is used to fill the gap between the first shell 310a and the sewage inlet pipe 112b to ensure that the suction force of the second suction device 500 can be concentrated in the leakage structure 312.

[0299] In an optional embodiment, a garbage leak-proof tube 319 is provided within the first housing 310a, and the sewage inlet pipe 112b is provided through the garbage leak-proof tube 319. After the first housing 310a is removed, the garbage leak-proof tube 319 can prevent garbage within the first bin 310 from falling out of the opening connected to the sewage inlet pipe 112b. Furthermore, a sixth seal 930 can be provided between the garbage leak-proof tube 319 and the sewage inlet pipe 112b to isolate the sewage inlet pipe 112b from the second bin 320. The sixth seal 930 can be provided on the top or inner sidewall of the garbage leak-proof tube 319. This can reduce the friction caused by the sealing ring between the sewage inlet pipe 112b and the garbage leak-proof tube 319 during the process of removing and placing the first housing 310a, making the removal and placement of the first housing 310a smoother. The sixth sealing member 930 may also be disposed at the bottom of the garbage leak-proof tube 319 , so that the sixth sealing member 930 can be installed from the opening of the garbage leak-proof tube 319 at the bottom of the first shell 310 a , facilitating assembly of the sixth sealing member 930 .

[0300] In an optional embodiment, if Figure 52As shown, a ridge 319a is provided along the inner wall of the garbage leak-proof tube 319 along its circumference. The end face of the sewage inlet pipe 112b abuts against the ridge 319a, and the sealing member is provided between the end face of the sewage inlet pipe 112b and the ridge 319a. When the sewage inlet pipe 112b is inserted into the garbage leak-proof tube 319 and in place, the two will apply axial pressure to the sealing ring. During the installation and removal of the two, the sealing ring does not contact another component, eliminating the frictional resistance caused by the sealing ring during installation and removal, making the removal and placement of the first shell 310a smoother. At the same time, because the first shell 310a is installed in the second shell 320 with an interference fit, the relative position between the first shell 310a and the second shell 320 can be stabilized, thereby ensuring the sealing performance of the sealing ring at this location.

[0301] In an optional embodiment, the first shell 310a is provided with a sewage inlet pipe through hole 310n, wherein the sewage inlet pipe 112b is passed through the sewage inlet pipe through hole 310n, and the sealing ring is arranged 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 sealed to each other through the circumferential surface, thereby reducing the possibility that when using end face sealing, the sealing effect will be affected due to the sewage inlet pipe 112b not being plugged in place or the sealing ring not being installed in place.

[0302] In the present application, the first chamber 310 and the second chamber 320 are used to hold dirt generated during the cleaning process of the cleaning device 10. However, excessive dirt will directly affect the normal operation of the cleaning device 10, and even worse, it will cause damage to the cleaning device 10. For example, sewage enters the first suction device 400 or the second suction device 500, causing damage to the cleaning device 10. In order to reduce the probability of such abnormality, the present application proposes the following solution:

[0303] In an optional embodiment, if Figure 7 、 9 As shown in Figures 57 and 58, the cleaning device 10 further includes a content detection component 360. The content detection component 360 includes a first detection component 361 and a second detection component 362, which are respectively used to detect content information in the first bin 310 and the second bin 320, so as to detect the contents of the first bin 310 and the second bin 320, and simultaneously detect the contents of the first bin 310 and the second bin 320. The content information may include solid waste capacity information, liquid level information, water presence information, etc.

[0304] For example, a filter is provided in the first bin 310, which can be used as a solid-liquid separation bin, and the first detection component 361 can be used to detect the capacity of solid waste. The second bin 320 is mainly used to store liquids, and therefore the second detection component 362 can be used to detect the liquid level inside the second bin 320. When the contents of either bin are full, the user will be notified to maintain the cleaning device 10, improving reliability and preventing damage to the cleaning device 10 or leakage caused by the user continuing to use the cleaning device 10 after only one bin is full, affecting the cleaning effect.

[0305] In an optional embodiment, if Figure 57 、 58 As shown, a first detection component 361 and a second detection component 362 connected in parallel with the first detection component 361, wherein the first detection component 361 is disposed in the first compartment 310, and the second detection component 362 is disposed in the second compartment 320. They are arranged in parallel here, and either the first detection component 361 or the second detection component 362 can generate a corresponding prompt after being triggered. The number of the first detection components 361 can be more than one, and they are respectively located at different positions of the first compartment 310, and these first detection components 361 are arranged in parallel.

[0306] In an optional embodiment, the first detection assembly 361 is located in the first chamber 310 and the second detection assembly 362 is located in the second chamber 320. For example, it can be located on the inner wall of the first chamber 310 or in the center of the cavity of the first chamber 310.

[0307] Furthermore, the cleaning device 10 further includes an electrical connector 364, which is connected to the first detection component 361 and the second detection component 362 (eg, Figure 57 As shown), the electrical connector 364 serves to lead out the signal; the exemplary first detection component 361 or the second detection component 362 can be a photoelectric detector; it can also be a capacitance detector; it can also be an electrode detector.

[0308] In other embodiments, Figure 58 As shown, the first detection component 361 and the second detection component 362 are formed by parts of the electrical connector 364. For example, the electrical connector 364 itself has a conductive property and can also serve as an electrode. Figure 58 As shown, the electrical connector 364 is set in the warehouse wall of the first warehouse 310, and a connection hole 367 is opened on the warehouse wall to connect the space in the warehouse with the electrical connector 364, and then the electrical connector 364 is directly used as a detection component, which can simplify the process, and the detection component and the signal transmission component can be integrally formed, with high reliability.

[0309] 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 wall surface of the first bin 310, i.e., the first shell 310a. For example, the electrical connector 364 is disposed on the surface of the first shell 310a. Alternatively, the first shell 310a may have a mounting slot or mounting hole extending in the vertical direction, and the electrical connector 364 is located in the mounting slot or mounting hole. The electrical connector 364 also includes a contact 365, which is used to output the signal of the electrical connector 364. The contact 365 is used to connect to the control device 600 of the cleaning device 10. When the water tank 300 is installed in place, the contact 365 is connected to the control device 600 to transmit signals. When the water tank 300 is removed, the contact 365 is disconnected from the control device 600. The contact 365 is located on the outer wall of the first housing 310a; and when the first housing 310a is nested in the second housing 320a, the contact 365 is located on the outer wall of the first housing 310a and exposed to a portion of the second housing 320a.

[0310] For example, the bottom of the electrical connector 364 extends into the second compartment 320 to form a second detection component 362. A connection hole 367 is opened on the wall of the first compartment 310, connecting the mounting groove or mounting hole and 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 a first detection component 361.

[0311] In an optional embodiment, the second detection component 362 is arranged on the upper part of the second warehouse 320; and / or, the first detection component 361 is arranged on the inner wall 310c of the first warehouse 310. The second detection component 362 can be arranged on the bottom of the second shell 320a, and can be set on the inner wall 310c of the first warehouse 310 when 320a is removed. This application does not impose any restrictions on this.

[0312] In an optional embodiment, there are two electrical connectors 364 , and the first detection component 361 includes a first electrode 3611 and a second electrode 3612 respectively connected to the two electrical connectors 364 ; the first electrode 3611 and the second electrode 3612 are both located in the first chamber 310 .

[0313] Since the triggering condition of the first detection component 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 alarms.

[0314] The first electrode 3611 and the second electrode 3612 have different heights, and the height difference is used to reduce the formation of a water film.

[0315] At least one of the first electrode 3611 and the second electrode 3612 is located at the top of the first chamber 310 . This arrangement ensures that the triggering is performed after the first chamber 310 is full. At least one of the first electrode 3611 and the second electrode 3612 is located at the bottom of the first chamber 310 .

[0316] At least one of the first electrode 3611 and the second electrode 3612 extends downward from the top wall of the first chamber 310 and forms a gap with the side wall of the first chamber 310. This arrangement can reduce the generation of water film between the first electrode 3611 and the second electrode 3612 and prevent false alarms.

[0317] First electrode 3611 and second electrode 3612 are positioned on either side of first chamber 310; for example, they can be positioned on either side of sewage suction pipe 112. This separation between the first and second electrodes reduces the likelihood of water film formation. This arrangement also allows for adequate space in first chamber 310, preventing the sensor from being triggered when all contents of first chamber 310 accumulate on one side while still having space on the other side, potentially causing a false alarm.

[0318] Exemplarily, at least one of the first electrode 3611 and the second electrode 3612 is disposed at the top or middle of the first chamber 310. When there is a large amount of content in the first chamber 310 and it contacts the electrode at the top, the two electrodes will be conductive due to the content, thereby triggering a signal that the content in the first chamber 310 has reached the detection position.

[0319] In an optional embodiment, one of the first electrode 3611 and the second electrode 3612 is disposed at the top of the first chamber 310 , and the other of the first electrode 3611 and the second electrode 3612 is disposed at the bottom of the first chamber 310 .

[0320] In an optional embodiment, there are two electrical connectors 364, and the second detection assembly 362 includes a third electrode and a fourth electrode, respectively connected to the two electrical connectors 364. One of the third electrode and the fourth electrode is disposed on the bottom surface of the first chamber 310. At least one of the third electrode and the fourth electrode may 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, thereby reducing the formation of a water film between the third electrode and the fourth electrode. Disposing the third and fourth electrodes in the first housing 310a in this manner simplifies the structure and processing of the second housing 320a. By arranging the second detection assembly 362 at the bottom of the first housing 310a, when the first housing 310a is in place, the second detection assembly 362 serves to detect the contents of the second housing 320a.

[0321] In an optional embodiment, a supporting protrusion is provided on the bottom surface of the first chamber 310, 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 provide support after the first chamber 310 is taken out, preventing the third electrode and / or the fourth electrode from contacting or colliding with the placement surface, protecting the third electrode and / or the fourth electrode, and also assisting the first chamber 310 to stand after being taken out.

[0322] In an alternative embodiment, see Figure 60 The cleaning device 10 also includes a third detection component 363, which includes a fifth electrode 3631 and a sixth electrode 3632. The second chamber 320 is also connected to the second suction channel 321. At least one of the fifth electrode 3631 and the sixth electrode 3632 is arranged in the second suction channel 321. When liquid enters the second suction channel 321, the electrode located in the second suction channel 321 will be connected to the other electrode. That is, at this time, the third detection component 363 can detect the entry of water into the second suction channel.

[0323] In an optional embodiment, if Figure 60 As shown, the fifth electrode 3631 and / or the sixth electrode 3632 arranged in the second suction channel 321 form a partition 321c arranged in the second suction channel 321, that is, the fifth electrode 3631 and / or the sixth electrode 3632 located in the second suction channel can detect the state of the incoming liquid in the suction channel, and the third electrode and / or the fourth electrode arranged in a partition shape can also directly block the liquid entering the suction channel.

[0324] In an optional embodiment, a plurality of partitions 321c are interlaced in the second suction channel 321, and the third electrode and / or the fourth electrode arranged in the suction channel are interlaced with the plurality of partitions 321c to form a curved airflow channel, which blocks the liquid while allowing the gas to pass smoothly, further preventing the liquid from being directly drawn into the gas suction device.

[0325] In an optional embodiment, the first detection component 361 is arranged on the front side of the first chamber 310 to prevent liquid from contacting the first detection component 361 when the first chamber 310 is in a lying state, thereby avoiding misjudgment by the first detection component 361.

[0326] In an optional embodiment, the first detection component 361 is disposed on the rear side of the top of the first chamber 310 and can be used to detect the backflow of liquid in the first chamber 310 when the cleaning device 10 lies down, and trigger it in time.

[0327] In an optional embodiment, the second detection component 362 is arranged at the front side of the second compartment 320 to prevent the liquid from contacting the second detection component 362 when the second compartment 320 is in a lying state, thereby preventing the second detection component 362 from making a misjudgment. The first detection component 361 and / or the second detection component 362 are arranged at the front side. When the main body 100 is lying down, the distance between the first detection component 361 and / or the second detection component 362 at the front side and the water level is the maximum, which can prevent the water level change caused by lying down from directly triggering the first detection component 361 and / or the second detection component 362. At the same time, the first detection component 361 and / or the second detection component 362 are located on the same side as the air intake 317, the first suction channel 311, and the second suction channel 321, respectively. When the water level rises to affect the working state of the air intake 317, the first detection component 361 and / or the second detection component 362 can perform synchronous detection.

[0328] In an optional embodiment, a retaining edge structure is provided around the outside of the first detection component 361 on the wall of the first warehouse 310 and / or the outside of the second detection component 362 on the wall of the second warehouse 320. The retaining edge structure can prevent the water film formed on the inner wall of the first warehouse 310 or the second warehouse 320 due to the surface tension of the liquid from connecting to the first detection component 361 and / or the second detection component 362, so as to prevent the water along the wall of the first warehouse 310 or the second warehouse 320 from affecting the misjudgment of the first detection component 361 or the second detection component 362.

[0329] In an optional embodiment, the first detection component 361 and / or the second detection component 362 and / or the third detection component 363 are photoelectric detectors. That is, the first detection component 361, the second detection component 362, and the third detection component 363 can be electrode-type detectors or photoelectric detectors, and can be arbitrarily combined.

[0330] like Figures 54-56As shown, according to the second aspect of the present application, an embodiment of the present application provides a cleaning device 10, including 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 rotatably connected to the chassis 200, the first bin 310 is arranged on the main body 100, the second bin 320 is connected to the first bin 310, the first suction device 400 is connected to the first bin 310 through a first suction channel 311, and the first suction device 400 provides power to drive external liquid into the first bin 310. The first suction device 400 is also connected to the second bin 320 through the second suction channel 321. The first suction device 400 provides power for the liquid in the first bin 310 to enter the second bin 320, so that a common first suction device 400 can provide the first bin 310 with power to suck external liquid into the first bin 310 and provide the second bin 320 with power to The liquid in the first chamber 310 is driven to enter the second chamber 320. The first suction device 400 suctions the first chamber 310 and the second chamber 320 through the independent first suction channel 311 and the second suction channel 321. When the external liquid is sucked into the first chamber 310, the gas is sucked out through the first suction channel 311. The liquid is sucked into the second chamber 320 through the leakage structure 312 connecting the first chamber 310 and the second chamber 320 for storage, so that the liquid in the first chamber 310 is always less, avoiding the liquid in the first chamber 310 from being filled, or when the cleaning device 10 is shaking, tilting or lying down, avoiding the liquid in the first chamber 310 from entering the first suction device 400. Moreover, since the first suction device 400 also has a certain suction effect on the leakage structure 312, it can effectively prevent the liquid in the second chamber 320 from flowing back into the first chamber 310. The structure is simple and practical. This solution is similar to the following. Figure 4-Figure 6 Compared with the solution shown in the figure, this solution only needs to use the first suction device 400 as a power source to achieve the suction and recovery of external liquid, while reducing the probability of water entering the first suction device 400, which can save costs.

[0332] In an optional embodiment, the second suction channel 321 includes a portion entirely or partially disposed on the side wall 310c of the first shell 310a, wherein the first suction device 400 is connected to the second warehouse 320 through the second suction channel 321 to provide negative pressure for the second warehouse 320. In this way, in addition to allowing the liquid in the first warehouse 310 to enter the second warehouse 320 under the action of gravity, the suction force of the first suction device 400 can also be used to assist the liquid in the first warehouse 310 to accelerate into the second warehouse 320.

[0333] In an optional embodiment, the cross-sectional area of ​​the first suction channel 311 is smaller than the cross-sectional area 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 better enter the second chamber 320.

[0334] In an optional embodiment, the negative pressure of the second chamber 320 is greater than the negative pressure of the first chamber 310 , so that the liquid in the first chamber 310 can better enter the second chamber 320 .

[0335] like Figures 1 to 56 As shown, according to the third aspect of the present application, an embodiment of the present application provides a water tank 300, which is configured to be installed on the main body 100 of the cleaning device 10, and the main body 100 is rotatably connected to the chassis 200 of the cleaning device 10. The water tank 300 includes a first chamber 310 and a second chamber 320. The first chamber 310 is provided on the main body 100 and can be communicated with a first suction device 400. The first suction device 400 provides power to drive external liquid into the first chamber 310; the second chamber 320 is communicated with the first chamber 310 and can be communicated with a second suction device 500. The second suction device 500 provides power to drive the liquid in the first chamber 310 into the second chamber 320.

[0336] like Figures 1 to 56As shown, according to the fourth aspect of the present application, an embodiment of the present application provides a water tank 300, which is configured to be installed on the main body 100 of the cleaning device 10, and the main body 100 is rotatably connected to the chassis 200 of the cleaning device 10. The water tank 300 includes a first chamber 310 and a second chamber 320, wherein the first chamber 310 is provided on the main body 100; the second chamber 320 is connected to the first chamber 310; the cleaning device 10 includes a first suction device 400, which is connected to the first chamber 310 through a first suction channel 311.

The first suction device 400 is also connected to the second chamber 320 through a second suction channel 321. The first suction device 400 provides power for the liquid in the first chamber 310 to enter the second chamber 320.

[0337] The present application forms two relatively independent first and second chambers 310 and 320 for the cleaning device 10 or the water tank 300, and provides an additional power to the second chamber 320 to drive the liquid in the first chamber 310 into the second chamber 320, so as to reduce the probability of water entering the first suction device 400 connected to the first chamber 310.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
