Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and particularly to a cleaning equipment and a cleaning system. Background Art

[0002] Cleaning equipment has the advantages of environmental protection, energy conservation, high efficiency, etc. With the increasing awareness of people on the efficiency of household cleaning, cleaning equipment has gradually been widely used in daily production and life.

[0003] Currently, after the cleaning equipment finishes working, users usually clean the sewage tank in time to drain the sewage and garbage in the sewage tank. The sewage tank is an important part of the cleaning equipment, and its main function is garbage collection.

[0004] However, the sewage tank is usually arranged on the body of the machine, and the weight of the body handle acting on the hands of consumers is large, which is not convenient for users to hold. In addition, the body size is large, and it cannot enter the low space after lying flat, which is not convenient for users to clean the low space, and the user experience is poor. Summary of the Invention

[0005] Embodiments of the present application provide a cleaning equipment and a cleaning system, which are used to solve the technical problems in the related art that the sewage tank is usually arranged on the body of the machine, the weight of the body handle acting on the hands of consumers is large, which is not convenient for users to hold. In addition, the body size is large, and it cannot enter the low space after lying flat, which is not convenient for users to clean the low space, and the user experience is poor.

[0006] In a first aspect, embodiments of the present application provide a cleaning equipment, including:

[0007] A floor brush; a rolling brush is arranged on the floor brush;

[0008] A body; the body is movably connected to the floor brush; a negative pressure source and a battery pack are arranged in the body;

[0009] A sewage tank; located on the floor brush; the sewage tank includes a box body, a sewage inlet and an exhaust port;

[0010] A clean water tank; located on the body of the machine;

[0011] Wherein, the negative pressure source and the battery pack are located at the lower part of the body; the clean water tank is located above the negative pressure source and the battery pack;

[0012] Wherein, a first chamber and a second chamber are arranged in the box body, the first chamber and the second chamber are arranged side by side in the horizontal direction; the first chamber and the second chamber are communicated; along the suction air flow direction of the negative pressure source, the second chamber is located downstream of the first chamber; a solid-liquid separation member is arranged in the first chamber.

[0013] By arranging the sewage tank on the floor brush, firstly, the loss of sewage and garbage during transmission can be reduced, the cleaning efficiency can be improved, and it can be ensured that the ground dirt can be quickly and effectively collected. Secondly, since the sewage tank is close to the floor brush, it is convenient for the user to directly pour out the sewage and garbage after cleaning, reducing the operation steps and cleaning time. In addition, the sewage tank located on the floor brush can form an upper and lower counterweight with the clean water tank on the body, which helps to optimize the overall center of gravity distribution of the cleaning device, making the cleaning device more stable during the cleaning process, reducing the shaking and cleaning dead angles caused by the unstable center of gravity, and improving the cleaning effect.

[0014] When the cleaning device is working, the dirt (including solid garbage and liquid sewage) sucked by the floor brush through the sewage suction port enters the first chamber of the sewage tank. The solid-liquid separation member uses its own structural characteristics to intercept the solid garbage on one side or the surface of the solid-liquid separation member, while the liquid sewage flows through the pores of the solid-liquid separation member or to the other side under the action of centrifugal force and flows into the second chamber downstream, thus realizing solid-liquid separation.

[0015] Furthermore, when the cleaning device is working, the dirt sucked by the floor brush first enters the first chamber, and in the first chamber, it is separated into solid garbage and sewage liquid by the solid-liquid separation member. The air flow carries the separated sewage liquid dirt and flows horizontally to the second chamber, and finally the air flow is discharged from the exhaust port of the second chamber.

[0016] Since the two chambers are arranged side by side, the flow path of the dirt in the sewage tank is relatively simple and smooth, without complex detours or up and down situations, reducing the energy loss of the dirt during the flow process and the collision with the sewage tank wall, thereby improving the collection efficiency of the dirt. At the same time, the above-mentioned side-by-side arrangement makes the overall structure of the sewage tank more compact, and a larger dirt collection capacity can be achieved in a limited space, improving the space utilization rate.

[0017] In a second aspect, the embodiments of the present application further provide a cleaning device, including:

[0018] A floor brush; a roller brush is arranged on the floor brush;

[0019] A body; the body is movably connected to the floor brush; a negative pressure source and a battery pack are arranged in the body;

[0020] A sewage tank; located on the floor brush; the sewage tank includes a box body, a sewage inlet and an exhaust port;

[0021] A clean water tank; located on the body;

[0022] Wherein, the negative pressure source and the battery pack are located at the lower part of the body; the clean water tank is located above the negative pressure source and the battery pack;

[0023] Wherein, a first chamber and a second chamber are arranged inside the box body, and the first chamber and the second chamber are arranged side by side in the horizontal direction; the first chamber and the second chamber are communicated with each other; in the horizontal projection direction, at least part of the roller brush overlaps with the first chamber and the second chamber; when the fuselage is in an upright state, in the vertical projection direction, at least part of the fuselage overlaps with the box body.

[0024] During the cleaning process, the roller brush is responsible for gathering the dirt on the ground and transporting it towards the sewage tank, while the first chamber and the second chamber of the sewage tank are responsible for collecting and treating this dirt. Since there is partial overlap between the two in the horizontal projection direction, the cleaning area of the roller brush and the collection area of the sewage tank can be better connected, enabling the dirt to directly enter the sewage tank after being swept by the roller brush, avoiding the scattering of dirt at other positions outside or inside the cleaning device. At the same time, this overlapping layout is also beneficial for the device to maintain a good cleaning effect in different cleaning directions and angles. For example, when cleaning the corner or the edge of furniture, the overlapping layout of the roller brush and the sewage tank can make the cleaning device closer to the surface to be cleaned, improving the convenience and thoroughness of cleaning.

[0025] In addition, when there is partial overlap between the fuselage and the box body in the vertical projection direction, the weight of the fuselage can be more directly transmitted to the box body through the overlapping area, and then transmitted to the ground by the box body, forming a stable support structure. At the same time, this overlapping arrangement enables the connecting components between the fuselage and the box body to achieve flexible rotation and positioning within a relatively small space range, reducing the problems of structural looseness and shaking caused by too far distance between components, and improving the operation accuracy and reliability of the cleaning device during the cleaning process.

[0026] In the above cleaning device, optionally, the dirt inlet is communicated with the first chamber, and the exhaust port is communicated with the second chamber.

[0035] In the above-mentioned cleaning device, optionally, it further includes a filtering component, and the filtering component is located in the floor brush outside the box body;

[0036] The filtering component is located downstream of the exhaust port and is opposite to the exhaust port in position.

[0037] In the above-mentioned cleaning device, optionally, the sewage tank is located in a groove with an upward opening at the top of the floor brush, and at least part of the upper cover is located in the groove.

[0039] In the above-mentioned cleaning device, optionally, the thickness of the floor brush is h2, the thickness of the fuselage is h3, and the relationship between h2 and h3 is: h2 ≥ h3.

[0040] In the above-mentioned cleaning device, optionally, when the fuselage is in a lying flat state, the top of the sewage tank is higher than the fuselage.

[0041] In the above-mentioned cleaning device, optionally, a driving motor is arranged in the roller brush, the driving motor is connected to the floor brush through a connecting part, and the connecting part is arranged close to the first chamber.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0065] In a first aspect, an embodiment of the present application provides a cleaning system (not shown in the figure), including a charging dock or a base station, and a cleaning device, and the cleaning device can be placed on the charging dock or the base station.

[0066] It can be understood that after the cleaning device finishes cleaning the cleaning surface, it can be placed on the charging dock or the base station for placement positioning, charging, self-cleaning, drying, or water supply and drainage. A placement position for the cleaning device is provided on the charging dock or the base station, so that the positioning placement of the cleaning device can be realized. A charging interface is provided on the charging dock or the base station, so that the charging of the cleaning device can be realized. A water inlet pipe and a sewage pipe can be provided on the base station to supply water to the clean water tank of the cleaning device and drain the sewage tank. A drying device can be provided on the charging dock or the base station for drying the cleaned cleaning device.

[0067] It should be noted that the charging dock or the base station generally needs to be fixed on the ground to support the operation of the cleaning device.

[0068] It can be understood that the cleaning device can be different types of devices. Exemplarily, the cleaning device can be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, or a floor washer, etc. Different types of cleaning devices all have corresponding base stations.

[0069] The following takes the cleaning device as a floor washer as an example for illustration.

[0070] Refer to Figure 1 , In a second aspect, an embodiment of the present application provides a cleaning device 10, and the cleaning device 10 includes a floor brush 100, a body 200, a sewage tank 300, and a clean water tank 400. Refer to Figure 2, wherein, a negative pressure source 210 and a battery pack 220 may be provided inside the body 200.

[0071] It can be understood that the floor brush 100 is adapted to perform a cleaning action on the surface A to be cleaned to achieve a cleaning effect. Among them, the surface A to be cleaned can be a floor or a wall with different roughness, and can also be a carpet or a blanket with different lengths or different types, or the surface of an object to be cleaned. The present application does not specifically limit the type of the surface A to be cleaned. Among them, the above cleaning action can be a dust suction action, a mopping action, or a simultaneous dust suction and mopping action to ensure the cleaning efficiency of the floor brush 100.

[0072] Refer to Figure 3 , further, a roller brush 110 may be provided on the floor brush 100. For example, the floor brush 100 includes a main body of the floor brush 100 and the roller brush 110. The roller brush 110 may be rotatably connected to the main body of the floor brush 100, and the roller brush 110 may achieve the cleaning of the surface A to be cleaned by rotation.

[0073] The body 200 is movably connected to the floor brush 100 so that the cleaning device 10 can have different states.

[0074] In some embodiments, the body 200 and the floor brush 100 may be rotationally connected. For example, a universal joint may be provided between the body 200 and the floor brush 100.

[0075] It can be understood that the body 200 and the floor brush 100 can rotate in different directions through the universal joint, so that the cleaning device 10 can have different states.

[0076] It should be noted that the cleaning device 10 can have different states may mean that there are different positions between the body 200 and the floor brush 100. The following is an example:

[0077] Exemplarily, when the body 200 is arranged to extend in the horizontal direction, that is, when the body 200 is in a lying flat state, both the floor brush 100 and the body 200 are arranged in the horizontal direction. In this state, the cleaning device 10 can be used to clean the surface A to be cleaned under the table, under the bed, etc.

[0078] Refer to Figure 1 and Figure 2 , it can be understood that when the body 200 is in a lying flat state, the center of gravity distribution and the overall size of the cleaning device 10 can better meet the cleaning requirements of low spaces. For example, when cleaning spaces such as under the sofa or under the bed, the horizontal posture of the cleaning device 10 enables it to enter these areas more smoothly.

[0079] Another exemplary situation is when the body 200 extends vertically or intersects with the vertical direction, that is, when the body 200 is in an upright state. In this state, the cleaning device 10 can be used by the user standing, so that the user can push the cleaning device 10 to clean the surface A to be cleaned. Among them, when the body 200 is in an upright state, it can rotate arbitrarily, and the user can rotate the body 200 arbitrarily according to their own situation.

[0080] It can be understood that the angle formed by the intersection of the body 200 and the vertical direction can be arbitrary. In the embodiments of the present application, the angle in the upright state is 4° - 7°. Preferably, the angle formed between the body 200 and the vertical direction is 5°.

[0081] Refer to Figure 1 and Figure 2 , it can be understood that when the body 200 is in an upright state, the overall height of the cleaning device 10 increases. When the user pushes the cleaning device 10, the hand can be located at a relatively high position, which conforms to the ergonomic principle and reduces the fatigue caused by uncomfortable postures such as bending and stooping.

[0082] Refer to Figure 1 and Figure 2 , in some embodiments, the negative pressure source 210 and the battery pack 220 are located at the lower part of the body 200. The negative pressure source 210 may refer to a suction fan used to provide the ability to suck dirt, and the battery pack 220 is electrically connected to the negative pressure source 210 to supply power for the suction fan to work.

[0083] It can be understood that the negative pressure source 210 and the battery pack 220 are relatively heavy. By arranging the negative pressure source 210 and the battery pack 220 at the lower part of the body 200, the overall center of gravity of the cleaning device 10 can be effectively reduced, which helps to improve the stability of the cleaning device 10 during the cleaning process, reduce the situation of tipping or shaking of the cleaning device 10 during the cleaning process, and enhance the user experience.

[0084] Refer to Figure 1 and Figure 2 , in some embodiments, the cleaning device 10 further includes a water tank 400. The water tank 400 is used to provide clean water for the cleaning device 10 to enable the floor brush 100 to mop the floor. Among them, the water tank 400 is located on the body 200 and above the negative pressure source 210 and the battery pack 220.

[0085] It can be understood that the water tank 400 can balance the weight distribution of the cleaning device 10 above, preventing the cleaning device 10 from shaking or tipping over due to unstable center of gravity during the cleaning process, and improving the stability and operability of the cleaning device 10. In addition, the water tank 400 is placed separately from the negative pressure source 210 and the battery pack 220, which can reduce mutual interference. For example, the water in the water tank 400 will not have a direct impact on the negative pressure source 210 and the battery pack 220 below, avoiding electrical failures caused by water splashing or leakage, and improving the safety and reliability of the cleaning device 10.

[0086] According to the foregoing, it can be seen that in the lying flat state, the weight distribution of the fuselage 200 also helps to maintain the stability of the cleaning device 10 during the cleaning process, avoiding problems such as collisions or inability to enter the cleaning area caused by the device being too high or having an unstable center of gravity; in the upright state, the fuselage 200 makes the center of gravity distribution of the cleaning device 10 more reasonable, and the user can more easily control the direction and force of the cleaning device 10 during the pushing process, ensuring the stability and accuracy of the cleaning process.

[0087] Refer to Figure 1 and Figure 2 , in some embodiments, the fuselage 200 further includes a circuit board 230, and the circuit board 230 is located above the negative pressure source 210 and the battery pack 220, that is, both the circuit board 230 and the water tank 400 are located above the negative pressure source 210 and the battery pack 220. Among them, when the fuselage 200 is in the lying flat state, the circuit board 230 can be located above the water tank 400 to prevent the water in the water tank 400 from affecting the circuit board 230.

[0088] In some embodiments, the fuselage 200 further includes a handheld part for the user to hold, and the handheld part is located above the water tank 400.

[0089] Refer to Figure 1 and Figure 3 , in some embodiments, the sewage tank 300 is located on the floor brush 100, and the sewage tank 300 is used to collect the dirt sucked by the floor brush 100 through the dirt suction port 101.

[0090] It can be understood that by arranging the sewage tank 300 on the floor brush 100, firstly, the loss of sewage and garbage during the transmission process can be reduced, the cleaning efficiency can be improved, and it can be ensured that the floor dirt can be quickly and effectively collected. Secondly, since the sewage tank 300 is close to the floor brush 100, it is convenient for the user to directly pour out the sewage and garbage after cleaning, reducing the operation steps and cleaning time. In addition, the sewage tank 300 located on the floor brush 100 can form an upper and lower counterweight with the water tank 400 on the fuselage 200, which helps to optimize the overall center of gravity distribution of the cleaning device 10, making the cleaning device 10 more stable during the cleaning process, reducing the shaking and cleaning dead angles caused by unstable center of gravity, and improving the cleaning effect.

[0091] Reference Figures 4 - 6 Figures 4 - 6 , in some embodiments, the sewage tank 300 includes a tank body, a sewage inlet 303, and an exhaust port 304. The sewage inlet 303 can be communicated with the sewage suction port 101, and the exhaust port 304 can be communicated with the negative pressure source 210 of the fuselage 200. That is, under the action of the negative pressure source 210 of the fuselage 200, the dirt is sucked by the cleaning device 10 under the suction of the air flow. Among them, the dirt and the air flow can sequentially pass through the sewage suction port 101 and the sewage inlet 303 into the tank body and stay in the sewage tank 300, and the air flow can sequentially pass through the sewage suction port 101 and the sewage inlet 303 into the tank body and flow to the negative pressure source 210 through the exhaust port 304 to complete the circulation of the air flow.

[0092] It can be understood that the cleaning device 10 can move along a preset traveling direction on the surface A to be cleaned to complete the cleaning process. The preset traveling direction refers to the traveling direction of the cleaning device 10.

[0093] In the preset traveling direction, the rotary brush 110 is usually located in front of the floor brush 100, the fuselage 200 is connected to the rear side of the floor brush 100, and the sewage tank 300 is located between the rotary brush 110 and the fuselage 200.

[0094] Reference Figures 4 - 6 Figures 4 - 6 , wherein, a first chamber 301 and a second chamber 302 are provided in the tank body.

[0095] It can be understood that the dirt can include sewage liquid and solid waste. To facilitate the user to clean the sewage tank 300, the first chamber 301 and the second chamber 302 can be a solid chamber and a liquid chamber for collecting solid waste and collecting sewage liquid, respectively.

[0096] Reference Figures 4 - 6 Figures 4 - 6 , in some embodiments, the first chamber 301 and the second chamber 302 are communicated, that is, the solid chamber is communicated with the liquid chamber. Along the suction air flow direction of the negative pressure source 210, the second chamber 302 is located downstream of the first chamber 301, that is, the air flow first enters the first chamber 301, and then flows from the first chamber 301 to the second chamber 302, and the second chamber 302 is in a relatively rear position.

[0097] Furthermore, in order to achieve solid-liquid separation, the sewage tank 300 is usually provided with a solid-liquid separation member 310 to realize the aforementioned solid chamber and liquid chamber. Specifically, the solid-liquid separation member 310 is provided in the first chamber 301.

[0098] It can be understood that the solid-liquid separation member 310 can be one or a combination of structures or devices such as a filter screen with a certain pore size, a filter plate, a centrifugal separation device, etc. In this way, the solid-liquid separation member 310 can effectively separate solids from liquids in the dirt entering the first chamber 301, separating solid waste and liquid sewage, facilitating subsequent separate treatment, and improving the efficiency and effect of dirt treatment in the sewage tank 300.

[0099] When the cleaning device 10 is working, the dirt (including solid waste and liquid sewage) sucked by the floor brush 100 through the dirt suction port 101 enters the first chamber 301 of the sewage tank 300. The solid-liquid separation member 310 utilizes its own structural characteristics, such as the pore size of the filter screen and the rotation speed of the centrifugal device, to intercept the solid waste on one side or the surface of the solid-liquid separation member 310, while the liquid sewage flows through the pores of the solid-liquid separation member 310 or flows to the other side under the action of centrifugal force and flows into the downstream second chamber 302, thus realizing solid-liquid separation.

[0100] In some embodiments, the solid-liquid separation member 310 is in a funnel shape, and the opening of the solid-liquid separation member 310 faces upward. That is, the upper part of the solid-liquid separation member 310 is wider and the lower part is narrower, forming a gradually shrinking structure, which is convenient for receiving the dirt entering from the dirt inlet 303.

[0101] It can be understood that the above-mentioned solid-liquid separation member 310 is beneficial to expanding the dirt receiving area, enabling more dirt to smoothly enter the solid-liquid separation member 310 for separation treatment. Specifically, under the action of gravity, due to the larger mass, the solid waste will gradually sink to the bottom of the solid-liquid separation member 310, while the liquid sewage is relatively concentrated in the upper part. This natural stratification phenomenon creates favorable conditions for subsequent solid-liquid separation, improving the efficiency and effect of separation.

[0102] In some embodiments, the solid-liquid separation member 310 has a filter screen structure for solid-liquid separation. Specifically, the filter screen has a specific pore size and pore distribution for intercepting solid waste, enabling the liquid sewage to flow out through the pores and realizing solid-liquid separation.

[0103] It can be understood that when the dirt containing solid waste and liquid sewage enters the solid-liquid separation member 310, under the action of the airflow generated by the negative pressure source 210, the liquid sewage will flow through the pores of the filter screen to the second chamber 302, while the solid waste is intercepted on the filter screen due to its size being larger than the pore size of the filter screen. By reasonably selecting the pore size of the filter screen, targeted separation can be carried out according to the particle distribution of the dirt during the actual cleaning process. For example, larger solid wastes such as dust particles, hair, and paper scraps can be intercepted, while allowing the liquid sewage and smaller particles to pass through, thus realizing efficient solid-liquid separation.

[0104] In some embodiments, the solid-liquid separation member 310 can be removed from the first chamber 301, that is, the solid-liquid separation member 310 is detachably arranged in the first chamber 301. The so-called detachable arrangement can be directly placed in the first chamber 301 or installed in the first chamber 301 through some structures such as snap-fit structures, screw connection structures, etc. The embodiments of the present application do not limit the setting manner of the fixed liquid separation member in the first chamber 301, nor are they limited to the above examples.

[0105] It can be understood that during use, a large amount of solid waste will gradually accumulate on the filter screen of the solid-liquid separation member 310. If not cleaned in time, it will affect the air permeability and separation effect of the filter screen, and may even cause the filter screen to be blocked, resulting in the sewage tank 300 being unable to work properly.

[0106] By designing the solid-liquid separation member 310 as a removable structure, the user can easily remove it from the first chamber 301, rinse, clean or replace the filter screen, thereby restoring its separation performance. In addition, this design also facilitates the user to inspect and repair the solid-liquid separation member 310, discover and solve potential problems in time, and ensure the long-term stable operation of the sewage tank 300.

[0107] It should be noted that the first chamber 301 and the second chamber 302 can be connected through a communication channel, and the communication channel can be located on the output side of the solid-liquid separation member 310.

[0108] Refer to Figures 4 - 6 , it can be understood that when the cleaning device 10 works, the dirt first enters the first chamber 301. After preliminary solid-liquid separation and sedimentation in the first chamber 301, the separated sewage liquid can flow into the second chamber 302 through the communication channel for more refined separation and collection.

[0109] If there is no communication channel, the dirt will all accumulate in the first chamber 301, which may cause the first chamber 301 to be quickly filled, affecting the continuous working ability of the cleaning device 10. The existence of the communication channel enables the sewage tank 300 to make more full use of the space and functions of the two chambers, improving the overall treatment efficiency of the dirt.

[0110] It should be noted that the communication channel has an input side and an output side. The input side faces the first chamber 301, and the output side faces the second chamber 302. The position of the communication channel can be arbitrary. Exemplarily, the input side and the output side are on the same horizontal plane, and the sewage liquid can flow naturally; the input side is higher than the output side, and the sewage liquid can flow naturally under the action of gravity; the input side is lower than the output side. At this time, a negative pressure structure can be arranged in the second chamber 302 or a positive pressure structure can be arranged in the first chamber 301 to drive the sewage liquid to overcome gravity and enter the second chamber 302, so as to realize that the second chamber 302 is downstream of the first chamber 301.

[0111] The embodiments of the present application do not limit the communication position and implementation manner of the communication channel, nor are they limited to the above examples.

[0112] Refer to Figures 4 - 6 , in some embodiments, the first chamber 301 and the second chamber 302 are arranged side by side in the horizontal direction, that is, the two chambers are adjacent to each other on the same horizontal plane, forming a side-by-side structural layout. The above structural layout can make reasonable use of the internal space of the sewage tank 300, and at the same time is beneficial to optimizing the flow path of the dirt in the sewage tank 300 and improving the collection and treatment efficiency of the dirt.

[0113] When the cleaning device 10 works, the dirt sucked by the floor brush 100 first enters the first chamber 301, and is separated into solid waste and sewage liquid in the first chamber 301 by the solid-liquid separation member 310. The airflow carries the separated sewage liquid and dirt and flows horizontally to the second chamber 302, and finally the airflow is discharged from the second chamber 302 through the exhaust port 304.

[0114] It can be understood that since the two chambers are arranged side by side, the flow path of the dirt in the sewage tank 300 is relatively simple and smooth, without complicated detours or up and down situations, reducing the energy loss of the dirt during the flow process and the collision with the wall of the sewage tank 300, thereby improving the collection efficiency of the dirt. At the same time, the above side-by-side arrangement makes the overall structure of the sewage tank 300 more compact, and can achieve a larger dirt collection capacity in a limited space, improving the space utilization rate.

[0115] It should be noted that the horizontal direction refers to the extension direction of the horizontal plane. Therefore, the side-by-side arrangement can include various possibilities, such as side-by-side left and right, side-by-side front and back, partially side-by-side up and down, and can also be side-by-side left front and right rear, etc. The embodiments of the present application do not limit the various forms of the side-by-side arrangement, nor are they limited to the above examples, that is, any side-by-side arrangement that satisfies the horizontal direction is within the protection scope of the present application.

[0116] In some embodiments, along the horizontal projection direction, the rolling brush 110 at least partially overlaps with the first chamber 301 and the second chamber 302. It can be understood that the horizontal projection direction refers to observing the positional relationship between the rolling brush 110 and the first chamber 301 and the second chamber 302 from the extending direction of the horizontal plane with the vertical plane as the projection reference. At this time, the rolling brush 110 and the first chamber 301 and the second chamber 302 at least partially overlap. The overlapping arrangement can optimize the internal space layout of the cleaning device 10, shorten the path for dirt to be sucked from the rolling brush 110 into the sewage tank 300, and improve the cleaning efficiency and dirt collection effect.

[0117] It should be noted that the overlapping part can be that a part of the area of the rolling brush 110 overlaps with a part of the areas of the first chamber 301 and the second chamber 302, or that most of the area of the rolling brush 110 overlaps with most of the areas of the first chamber 301 and the second chamber 302, or that the entire rolling brush 110 is located within the areas of the first chamber 301 and the second chamber 302, or that the entire first chamber 301 and the second chamber 302 are located within the area of the rolling brush 110. The embodiments of the present application do not limit the degree of overlap and are not limited to the above examples.

[0118] During the cleaning process, the rolling brush 110 is responsible for gathering the dirt on the ground and transporting it towards the sewage tank 300, while the first chamber 301 and the second chamber 302 of the sewage tank 300 are responsible for collecting and treating this dirt. Since there is partial overlap between the two in the horizontal projection direction, the cleaning area of the rolling brush 110 and the collection area of the sewage tank 300 can be better connected, so that the dirt can directly enter the sewage tank 300 after being swept by the rolling brush 110, avoiding the scattering of dirt at other positions outside or inside the cleaning device 10. At the same time, this overlapping layout is also beneficial for the device to maintain a good cleaning effect in different cleaning directions and angles. For example, when cleaning the corner or the edge of furniture, the overlapping layout of the rolling brush 110 and the sewage tank 300 can make the cleaning device 10 closer to the surface A to be cleaned, improving the convenience and thoroughness of cleaning.

[0119] In some embodiments, when the body 200 is in an upright state, along the vertical projection direction, the body 200 and the box body at least partially overlap.

[0120] It can be understood that the vertical projection direction refers to observing the positional relationship between the body 200 and the box body from the vertical direction with the horizontal direction as the projection reference, that is, performing a vertical projection from top to bottom or from bottom to top.

[0121] When there is partial overlap between the body 200 and the box body in the vertical projection direction, the weight of the body 200 can be more directly transmitted to the box body through the overlapping area, and then transmitted to the ground by the box body, forming a stable support structure. At the same time, this overlapping arrangement enables the connecting part 130 (such as a universal joint, etc.) between the body 200 and the box body to achieve flexible rotation and positioning within a relatively small space range, reducing the problems of structural looseness and shaking caused by excessive distance between components, and improving the operation accuracy and reliability of the cleaning device 10 during the cleaning process.

[0122] It should be noted that since there is partial overlap between the body 200 and the box body in the vertical projection direction, the weight of the body 200 and the weight of the box body are balanced and close to each other to a certain extent, making the center of gravity of the entire cleaning device 10 close to the bottom center, and being able to better resist the overturning moment caused by external factors (such as uneven ground, changes in user pushing force, etc.), and maintaining the stable operation of the cleaning device 10. The stable posture of the cleaning device 10 helps the floor brush 100 to maintain good contact with the surface A to be cleaned and the cleaning effect, reducing cleaning dead corners and dirt omission caused by the shaking or tilting of the cleaning device 10. As an alternative implementation manner, when the body 200 is in a lying flat state, the top of the sewage tank 300 is higher than the body 200.

[0123] According to the foregoing content, it can be known that the cleaning device 10 in the lying flat state can be used to clean the surface A to be cleaned in low spaces such as under the table and under the bed. As long as the floor brush 100 can enter the low space, the body 200 in the lying flat state can enter, which can significantly increase the cleaning range of the low space and reduce cleaning dead corners.

[0124] Since the top of the sewage tank 300 is higher than the body 200, the opening position of the sewage tank 300 is relatively high. After the cleaning device 10 completes the cleaning task, the user can more conveniently pour out the sewage and garbage in the sewage tank 300, reducing the operation difficulty and time cost when cleaning the sewage tank 300. In addition, the relative height of the sewage tank 300 also helps to optimize the overall center of gravity distribution of the cleaning device 10, making the cleaning device 10 more stable in the lying flat state, and avoiding the front end of the device being too heavy due to the sewage tank 300 being too low, which affects the balance and operation accuracy during cleaning.

[0125] It can be understood that the top of the sewage tank 300 can be flush with the top of the body 200. In addition, the top of the sewage tank 300 can also be higher than the top of the body 200, that is, there is a height difference between the top of the sewage tank 300 and the top of the body 200. The specific value of this height difference in the embodiments of the present application is not limited, nor is it limited to the above examples.

[0126] It should be noted that the top of the sewage tank 300 here can refer to the structure of the sewage tank 300 itself or the structure used to assist in the use of the sewage tank 300. The structure at the top of the sewage tank 300 can include, but is not limited to, the upper cover 320 of the sewage tank 300, the handle for the user to pick up, etc. The embodiments of the present application do not limit this and are not limited to the above examples.

[0127] Referring to Figure 1 , as an optional implementation manner, the thickness of the sewage tank 300 is h1, and the thickness of the floor brush 100 is h2. The relationship between h1 and h2 is: h1 ≤ h2.

[0128] It can be understood that if the thickness h1 of the sewage tank 300 is greater than the thickness h2 of the floor brush 100, the sewage tank 300 will protrude above or below the floor brush 100 after installation, which will not only affect the overall appearance and portability of the device, but may also collide with other objects during the cleaning process, damaging the sewage tank 300 or the device.

[0129] When the thickness h1 of the sewage tank 300 is less than or equal to the thickness h2 of the floor brush 100, the sewage tank 300 can be better embedded in the installation space of the floor brush 100, forming a relatively flat surface with the floor brush 100. This not only improves the aesthetics and portability of the device, but also provides a more stable operation experience for the user during the cleaning process, avoiding the risk of collision and damage caused by the protrusion of the sewage tank 300.

[0130] It can be understood that the specific dimensional relationship between the sewage tank 300 and the floor brush 100 can be selected according to the actual situation. The embodiments of the present application do not limit this and are not limited to the above examples.

[0131] It should be noted that the thickness h2 of the floor brush 100 refers to the maximum thickness, that is, the distance between the surface A to be cleaned and the horizontal plane where the top of the floor brush 100 is located.

[0132] In some embodiments, the thickness h2 of the floor brush 100 can be any value between 61 mm and 85 mm, and the thickness h1 of the sewage tank 300 can be any value between 30 mm and 85 mm. Exemplarily, the thickness h1 of the sewage tank 300 can be 30 mm, and the thickness h2 of the floor brush 100 can be 61 mm; in another example, the thickness h1 of the sewage tank 300 can be 61 mm, and the thickness h2 of the floor brush 100 can be 85 mm; in yet another example, the thickness h1 of the sewage tank 300 can be 85 mm, and the thickness h2 of the floor brush 100 can be 85 mm.

[0133] Referring to Figure 1, As an alternative embodiment, the thickness of the floor brush 100 is h2, and the thickness of the body 200 is h3. The relationship between h2 and h3 is: h2 ≥ h3.

[0134] It can be understood that if the thickness h2 of the floor brush 100 is less than the thickness h3 of the body 200, that is, the size of the body 200 is relatively large, it may cause the center of gravity of the cleaning device 10 to be too high, affecting the stability during cleaning.

[0135] According to the foregoing content, when the cleaning device 10 is in a lying flat state, the design of h2 ≥ h3 means that the top of the floor brush 100 is higher than the body 200, making the cleaning device 10 more stable in the lying flat state, and avoiding the front end of the device from being too heavy due to the too low sewage tank 300, which affects the balance and operation accuracy during cleaning. In addition, the above-mentioned size design is beneficial for users to use both the body 200 and the floor brush 100 to clean the surface to be cleaned A under the table, under the bed and other low spaces, so as to clean the areas that are not easy to clean, such as deep under the table and deep under the bed, which can improve the user experience.

[0136] According to the foregoing content, the thickness h2 of the floor brush 100 can be any value between 61 mm and 85 mm.

[0137] In some embodiments, the thickness h3 of the body 200 can be any value between 45 mm and 85 mm. Exemplarily, the thickness h3 of the body 200 can be 45 mm, and the thickness h2 of the floor brush 100 can be 70 mm; in another example, the thickness h3 of the body 200 can be 85 mm, and the thickness h2 of the floor brush 100 can be 85 mm; in yet another example, the thickness h3 of the body 200 can be 60 mm, and the thickness h2 of the floor brush 100 can be 65 mm.

[0138] The following specifically introduces the structure of the sewage tank 300 itself.

[0139] As an alternative embodiment, the sewage inlet 303 is used to receive the dirt sucked by the floor brush 100. The sewage inlet 303 is connected to the first chamber 301 so that the dirt can smoothly enter the first chamber 301 from the sewage inlet 303.

[0140] The exhaust port 304 is an outlet for discharging the filtered and treated clean air. The exhaust port 304 is connected to the second chamber 302 so that the air flow can be discharged from the sewage tank 300 through the exhaust port 304 after passing through the second chamber 302.

[0141] When the cleaning device 10 is working, the dirt sucked by the floor brush 100 through the dirt suction port 101 enters the first chamber 301 of the sewage tank 300 under the action of the negative pressure source 210. In the first chamber 301, due to the presence of the solid-liquid separation member 310, the dirt can be processed in stages in the sewage tank 300 according to different properties, enabling the sewage liquid to enter the second chamber 302, avoiding the chaos and difficult processing caused by all the dirt directly entering the same space, thereby improving the efficiency of the entire cleaning system.

[0142] When the airflow and the sewage liquid enter the second chamber 302, the dirt has been intercepted and collected. If the exhaust port 304 is directly connected to the first chamber 301, since there is still a large amount of unprocessed dirt in the first chamber 301, the discharged air may carry a large number of dirt particles, causing secondary pollution to the environment.

[0143] As an alternative embodiment, the dirt inlet 303 is located on the side of the box body facing the roller brush 110, which is beneficial to shortening the distance for the dirt to be sucked from the roller brush 110 into the sewage tank 300, improving the efficiency of dirt collection, and reducing the energy loss and splashing of the dirt during transmission.

[0144] Refer to Figures 4 - 6 , further, the dirt inlet 303 and the floor brush 100 are connected through the first suction pipe 150. The first suction pipe 150 can effectively transport the dirt collected by the floor brush 100 to the sewage tank 300 quickly and stably, ensuring the continuous collection of dirt during the cleaning process and improving the cleaning efficiency and effect.

[0145] When the cleaning device 10 is working, the suction force generated by the negative pressure source 210 is transmitted to the dirt suction area of the floor brush 100 through the first suction pipe 150, enabling the floor brush 100 to smoothly suck the dirt on the surface A to be cleaned. The connectivity of the first suction pipe 150 ensures that the dirt can be transported from the floor brush 100 to the dirt inlet 303 of the sewage tank 300 along the preset path, avoiding leakage or blockage of the dirt during transmission. For example, if there is no good pipeline connection between the dirt inlet 303 and the floor brush 100, or if there are problems such as bending or blockage in the pipeline, it will result in insufficient suction force and the dirt cannot enter the sewage tank 300 smoothly, thereby affecting the performance of the cleaning device 10.

[0146] It should be noted that the parameters such as the diameter, length, and shape of the first suction pipe 150 in the embodiments of the present application are not limited, as long as it can ensure the smooth flow of the dirt in the pipeline and enable the cleaning device 10 to continuously and stably perform the cleaning work.

[0147] As an alternative embodiment, the connection between the sewage inlet 303 and the first chamber 301 is located at the upper part of the side wall of the first chamber 301, which is beneficial for the sewage to fully utilize the gravity to settle and separate after entering the first chamber 301, and at the same time avoids the splashing and secondary pollution that may be caused by the direct impact of the sewage on the bottom of the first chamber 301. By forming a height difference, the sewage in the first chamber 301 is prevented from flowing back to the sewage inlet 303.

[0148] Furthermore, the connection between the sewage inlet 303 and the first chamber 301 is located above the solid-liquid separation member 310, so that the incoming sewage first passes through the solid-liquid separation member 310 for treatment. In this way, the sewage tank 300 can utilize the function of the solid-liquid separation member 310 to perform timely and effective solid-liquid separation on the incoming sewage, separating solid wastes such as hair, paper scraps, particulate matters, and fruit peels from the liquid, improving the separation efficiency, and at the same time avoiding the accumulation and blockage of the sewage in other areas of the first chamber 301.

[0149] In some embodiments, the sewage inlet 303 may be disposed in the area between the first chamber 301 and the second chamber 302, that is, the first suction pipeline 150 may be located in the area between the first chamber 301 and the second chamber 302.

[0150] It can be understood that the first suction pipeline 150 needs to occupy a certain space, and this space may be located in the first chamber 301, or in the second chamber 302, or in the sewage tank 300 outside the first chamber 301 and the second chamber 302, or in the floor brush 100 in the sewage tank 300. The embodiments of the present application do not limit the specific position and connection direction of the first suction pipeline 150, nor are they limited to the above examples.

[0151] Refer to Figures 4 - 6 , as an alternative embodiment, the exhaust port 304 is connected to the negative pressure source 210 through a second suction pipeline 160. That is, when the cleaning device 10 is working, the suction force generated by the negative pressure source 210 acts on the exhaust port 304 through the second suction pipeline 160, so that the air in the second chamber 302 can be smoothly discharged.

[0152] Furthermore, the path length of the first suction pipeline 150 is less than the path length of the second suction pipeline 160. The design difference in the above path lengths can optimize the suction efficiency and energy utilization of the cleaning device 10, improve the effect of sewage collection, and at the same time reduce the flow resistance of the air in the pipeline and ensure the smoothness of exhaust.

[0153] The shorter first suction pipe 150 can reduce the residence time of dirt in the pipe and energy loss, improve the transfer efficiency of the suction force, enable the dirt to be sucked into the sewage tank 300 more quickly, and thus improve the cleaning efficiency. The longer second suction pipe 160 can more simply achieve the connection between the negative pressure source 210 and the second chamber 302, can optimize the spatial layout inside the cleaning device 10, and improve the stability and reliability of the device.

[0154] In some embodiments, the ratio range between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 can be 1 - 3 times.

[0155] Exemplarily, the path length of the first suction pipe 150 can be 40 mm, the path length of the second suction pipe 160 can be 120 mm, and the ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 is 3 times.

[0156] Exemplarily, the path length of the first suction pipe 150 can be 60 mm, the path length of the second suction pipe 160 can be 120 mm, and the ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 is 2 times.

[0157] Exemplarily, the path length of the first suction pipe 150 can be 50 mm, the path length of the second suction pipe 160 can be 100 mm, and the ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 is 2 times.

[0158] Exemplarily, the path length of the first suction pipe 150 can be 70 mm, the path length of the second suction pipe 160 can be 105 mm, and the ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 is 1.5 times.

[0159] Exemplarily, the path length of the first suction pipe 150 can be 60 mm, the path length of the second suction pipe 160 can be 66 mm, and the ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 is 1.1 times.

[0160] The specific ratio between the path length of the second suction pipe 160 and the path length of the first suction pipe 150 in the embodiments of the present application is not limited to the above examples.

[0161] Refer to Figure 3, As an alternative embodiment, the sewage tank 300 further includes an upper cover 320. The upper cover 320 is used to seal the top of the first chamber 301 and the top of the second chamber 302, and is used to cover the interior of the tank body and protect the interior of the tank body. The provision of the upper cover 320 can effectively prevent the dirt in the sewage tank 300 from leaking out, avoid sewage and garbage from overflowing or emitting odors from the sewage tank 300 during the cleaning process or when the device is moved, and keep the environment around the device clean; at the same time, the upper cover 320 can also prevent external dust, debris, etc. from entering the sewage tank 300, ensuring the cleanliness of the interior of the sewage tank 300 and the accuracy of dirt collection.

[0162] The upper cover 320 is arranged at the top position. When operating, the user can easily complete the cleaning and maintenance work without bending down or overstretching the body, improving the user experience and the maintainability of the device.

[0163] The upper cover 320 is openably arranged on the top of the tank body, such as connected by mechanical structures such as hinges and buckles, so that the upper cover 320 can be conveniently opened and closed.

[0164] It can be understood that when the sewage tank 300 needs to be cleaned, the user only needs to open the upper cover 320 to directly access the first chamber 301 and the second chamber 302 inside the sewage tank 300, and can conveniently take out the solid-liquid separation member 310 for cleaning or replacing the filter screen, and clean the dirt deposition in the chamber.

[0165] In some embodiments, according to the foregoing content, when the charging base or the base station is used for water supply and drainage, an outlet channel can be provided on the charging base or the base station, and the outlet channel can communicate with the sewer in the user's home. At this time, the sewage tank 300 can have an outlet connected to the base station, and the outlet is communicated with the outlet channel. The outlet can be located at the bottom of the sewage tank 300 to discharge water naturally under the action of gravity.

[0166] It should be noted that the outlet channel has an input side and an output side. The input side faces the sewage tank 300 (such as the second chamber 302), and the output side faces the sewer. The position of the outlet channel can be arbitrary. Exemplarily, the input side and the output side are on the same horizontal plane, and the sewage liquid can flow naturally; the input side is higher than the output side, and the sewage liquid can flow naturally under the action of gravity; the input side is lower than the output side. At this time, a positive pressure structure can be provided in the second chamber 302 or a positive pressure structure can be provided in the base station to drive the sewage liquid to overcome gravity and move out of the second chamber 302 and enter the communication channel to realize the discharge of sewage.

[0167] The embodiments of the present application do not limit the connection position and implementation manner of the outlet channel, nor are they limited to the above examples.

[0168] Refer to Figures 4 - 6, As an alternative implementation, the cleaning device 10 further includes a filter assembly 140, and the filter assembly 140 is located in the floor brush 100 outside the box body. That is, the filter assembly 140 forms a relatively independent structure with the sewage tank 300. In this way, it is beneficial to optimize the utilization of the internal space of the cleaning device 10, avoid the filter assembly 140 occupying the dirt collection space inside the sewage tank 300, and at the same time facilitate the maintenance and replacement of the filter assembly 140 without affecting the normal use function of the sewage tank 300.

[0169] The filter assembly 140 is located downstream of the exhaust port 304, and the filter assembly is opposite to the exhaust port 304. That is, the air first passes through the exhaust port 304 and is discharged from the sewage tank 300, and then passes through the filter assembly 140.

[0170] It can be understood that setting the filter assembly 140 downstream of the exhaust port 304 can intercept and filter the particulate matter remaining in the air flow, further improving the air cleanliness. If the filter assembly 140 is located upstream of the exhaust port 304, that is, filtering before the air enters the sewage tank 300, then the filter assembly 140 may be quickly blocked by a large amount of dirt, resulting in a decline in the filtering effect and the need for frequent cleaning or replacement. The downstream position can enable the filter assembly 140 to process relatively cleaner air, reduce its filtering burden, and extend the service life.

[0171] It should be noted that the filter assembly 140 can also be located upstream of the negative pressure source 210, that is, the air flow can pass through the filter assembly 140 and flow to the negative pressure source 210, and the filter assembly 140 can protect the negative pressure source 210.

[0172] Exemplarily, the filter assembly 140 can include, but is not limited to, a HEPA filter. The HEPA filter refers to a High-Efficiency Particulate Air Filter, which has high filtering performance and can effectively intercept minute particulate matter in the air, such as dust, pollen, bacteria, etc. The HEPA filter can significantly improve the filtering efficiency of the cleaning device 10, ensure that the discharged air is cleaner, reduce environmental pollution, and enhance the user experience.

[0173] It should be noted that the HEPA filter affected by water will affect its filtering effect. During the process when the user takes out the sewage tank 300 for cleaning the sewage tank 300, the HEPA filter set on the floor brush 100 will not come into contact with water and thus will not be wetted. In this way, the filtering performance of the HEPA filter can be guaranteed, the service life of the HEPA filter can be extended, and the user experience can be enhanced.

[0174] Refer to Figure 3, As an alternative implementation, a driving motor 120 is disposed within the rotary brush 110. The driving motor 120 is connected to the floor brush 100 through a connecting portion 130, and the connecting portion 130 is disposed near the first chamber 301.

[0175] It can be understood that the driving motor 120 is used to drive the rotary brush 110 to rotate. The rotary brush 110 is usually provided with a hollow space, and the driving motor 120 can be disposed within the aforementioned hollow space. Further, the floor brush 100 is connected to the driving motor 120 through the connecting portion 130 to fix the rotary brush 110.

[0176] It should be noted that, in the extending direction of the rotation axis of the rotary brush 110, the size of the driving motor 120 is usually smaller than that of the rotary brush 110, that is, the driving motor 120 is located on one side of the rotary brush 110.

[0177] When the cleaning device 10 operates, the dirt in the sewage tank 300 gradually increases, the solid waste in the first chamber 301 gradually increases, and the sewage liquid in the second chamber 302 gradually increases.

[0178] It can be understood that the solid waste in the first chamber 301 usually includes dust, hair, etc. As the cleaning process progresses, the weight of the sewage liquid in the second chamber 302 will be greater than the weight of the solid waste in the first chamber 301.

[0179] To evenly distribute the weight of the floor brush 100 on the horizontal plane, the driving motor 120 can be located closer to the first chamber 301 relative to the second chamber 302, that is, the connecting portion 130 is disposed near the first chamber 301, so that the driving motor 120 and the second chamber 302 can be diagonally distributed, thereby forming a floor brush 100 with a uniform weight distribution, which can improve the use stability of the cleaning device 10 and facilitate user operation.

[0180] As an alternative implementation, the sewage tank 300 is located within a groove on the top of the floor brush 100 with an upward opening, and the groove provides a dedicated placement space for the sewage tank 300. The groove enables the sewage tank 300 and the floor brush 100 to be closely combined. The above setting can optimize the overall spatial layout of the cleaning device 10, reduce the volume of the cleaning device 10, and facilitate the installation and removal of the sewage tank 300.

[0181] It can be understood that, to ensure the tight installation of the sewage tank 300 on the floor brush 100, the shape of the groove can be set to match the shape of the sewage tank 300. Exemplarily, if the shape of the sewage tank 300 is a cuboid, the shape of the groove can also be a cuboid.

[0182] At least part of the upper cover 320 is located in the groove, that is, when the upper cover 320 of the sewage tank 300 is in the closed state, at least part of the upper cover 320 is located in the groove at the top of the floor brush 100 .

[0183] Specifically, the upper cover 320 is partially located in the groove, which can make the connection between the upper cover 320 and the floor brush 100 and the sewage tank 300 tighter. When the upper cover 320 is closed, the groove can provide additional support for the upper cover 320, reduce the shaking and loosening of the upper cover 320 during use, and thus improve the sealing effect.

[0184] In some embodiments, in order to ensure that the upper cover 320 can maintain the sealing of the first chamber 301 and the second chamber 302 during the cleaning process, the upper cover 320 can be provided with a locking piece. When the cleaning device 10 is in the cleaning operation state, the locking piece can lock the sewage tank 300, such as locking the upper cover 320 or locking the position of the sewage tank 300 and the floor brush 100.

[0185] The aforementioned locking member may include but is not limited to rotation locking, thread locking, snap locking, buckle locking, etc. The embodiment of the present application does not limit the specific implementation method of the locking member, nor is it limited to the above examples.

[0186] Reference Figure 1 As an optional implementation, a clearance portion 201 is provided at the bottom of the body 200, and the clearance portion 201 is used to provide space for other components to facilitate the reasonable layout and installation of various components inside the device, such as the removal and placement of the sewage tank 300.

[0187] By providing the clearance portion 201, necessary installation space can be provided for components such as the sewage tank 300 to avoid mutual interference between the components. For example, the sewage tank 300 needs to be installed at the bottom of the body 200 near the floor brush 100 to facilitate the collection and transmission of dirt. The existence of the clearance portion 201 allows the sewage tank 300 to be better embedded in the bottom of the body 200, thereby optimizing the overall layout of the cleaning device 10, making the device more compact and lightweight, and convenient for users to carry and operate.

[0188] It is understandable that, when the user takes or installs the sewage tank 300, according to the above content, in order to achieve the miniaturization of the cleaning device 10, the body 200 is relatively close to the floor brush 100. Therefore, the user cannot take the sewage tank 300 in a straight up and down manner.

[0189] When the user takes out the sewage tank 300 for cleaning, the user may first move the sewage tank 300 vertically upward and then move it horizontally away from the body 200 to take out the sewage tank 300; or, the user may move the sewage tank 300 vertically upward and move it horizontally away from the body 200 to take out the sewage tank 300.

[0190] When the user installs the cleaned sewage tank 300, the user may first move the sewage tank 300 vertically downward, then approach the body 200 in the horizontal direction, and finally move the sewage tank 300 vertically downward to complete the installation; or, the user may move the sewage tank 300 vertically downward while approaching the body 200 in the horizontal direction to install the sewage tank 300.

[0191] The yielding portion 201 refers to a region where interference may occur between the sewage tank 300 and the body 200 during the above process.

[0192] In some embodiments, the recessed portion 201 is concave to provide an embedded installation space for the sewage tank 300. Specifically, the recessed recessed portion 201 reduces the interference between the sewage and the body 200 when the user takes the sewage tank 300, thereby affecting the user's experience.

[0193] It is understandable that the shape of the concave relief portion 201 may include but is not limited to regular shapes or irregular shapes such as a cuboid and a cylinder. The embodiment of the present application does not limit the specific shape of the relief portion 201, nor is it limited to the above examples.

[0194] The height of the clearance portion 201 is greater than or equal to the height of the sewage tank 300. The height refers to the dimension in the vertical direction, that is, the height dimension of the clearance portion 201 in the vertical direction is greater than or equal to the height dimension of the sewage tank 300, ensuring that the sewage tank 300 can be completely or mostly contained in the clearance portion 201 during the taking path, thereby avoiding interference with the body 200.

[0195] The width of the clearance portion 201 is less than or equal to the width of the sewage tank 300. The width here refers to the dimension on the horizontal plane in the preset direction of travel. According to the above content, in the preset direction of travel, the roller brush 110 is located at the front side of the floor brush 100, and the body 200 is connected to the rear side of the floor brush 100, so there is a certain space above the sewage tank 300 for taking. In this way, the user can use the space above the sewage tank 300 when taking the sewage tank 300, so the width of the clearance portion 201 only needs to be less than the width of the sewage tank 300.

[0196] In some embodiments, in order to reduce the size of the clearance portion 201 to ensure the size of the body 200, the width of the clearance portion 201 can be less than 1 / 3 of the width of the sewage tank 300. In this way, while ensuring the size of the body 200, the sewage tank 300 can be ensured not to interfere with the body 200 during the taking process.
