Description

Technical Field

[0001] The present disclosure relates to the field of cleaning equipment, and more specifically, to a cleaning equipment and a cleaning system. Background Art

[0002] With the development of social productivity, people's living standards have also been improved. On the premise that the material foundation is guaranteed, people begin to use various tools to reduce labor and improve the quality of life, and cleaning equipment comes into being. Cleaning equipment usually includes a body and a floor brush assembly, a clean water tank and a sewage bucket arranged on the body. When in use, the user pushes and pulls the body to make the floor brush assembly reciprocate on the working surface, thereby cleaning the working surface.

[0003] If you want to clean the bottom of the bed or sofa, you need to lay the machine down to extend the floor brush assembly into these cleaning areas. However, the existing cleaning equipment is heavy and it is difficult for users to pull the machine, which affects the user experience. In addition, in the existing cleaning equipment, the sewage bucket is set on the machine body. If the machine body is laid down, the dirt in the sewage bucket may flow into the fan assembly through the air inlet, causing damage to the equipment. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a cleaning device and a sewage bucket.

[0005] According to a first aspect of the present disclosure, a cleaning device is provided, wherein a side of the cleaning device facing a user is referred to as a rear side, and a side away from the user is referred to as a front side, comprising:

[0006] Floor brush assembly;

[0007] A machine body, the machine body being configured to be able to rotate relative to the brush assembly to make its extension direction parallel to the working surface so as to be in a flat lying state, and a sewage bucket is provided at the front side of the machine body;

[0008] The sewage bucket includes a bucket cover and a bucket body, and a sewage inlet channel is arranged in the bucket body. The bucket cover of the sewage bucket is provided with a main partition, an air outlet and a guide channel. The two opposite sides of the main partition are in contact with the bucket body and extend along the extension direction of the body, and the upper part of the inner cavity is divided into a first area located on the front side and a third area located on the rear side. The sewage inlet channel is arranged in the third area, and the air outlet is arranged in the first area. The outlet of the guide channel is constructed to be higher than the main partition when the body is in a flat state, and the inlet of the guide channel is connected with the sewage inlet channel.

[0009] According to a second aspect of the present disclosure, there is provided a sewage bucket, comprising a bucket cover and a bucket body, wherein a sewage inlet channel is arranged in the bucket body, and a main partition, an air outlet and a flow guide channel are arranged on the bucket cover of the sewage bucket, wherein opposite sides of the main partition are in contact with the bucket body and extend along the extension direction of the sewage bucket, and the upper part of the inner cavity is divided into a first area located at the front side and a third area located at the rear side, wherein the sewage inlet channel is arranged in the third area, and the air outlet is arranged in the first area;

[0010] The inlet of the guide channel is communicated with the sewage inlet channel, and the guide channel extends from the inlet thereof through the main partition plate to form an outlet located in the first area.

[0011] Since the main partition can separate the upper area of ​​the inner cavity into a first area located at the front side and a third area located at the rear side, and the sewage inlet channel is arranged in the third area, the air outlet is arranged in the first area, and the guide channel is arranged through the main partition, the inlet and outlet of the guide channel are separated by the main partition at the front and rear sides of the inner cavity, and the inlet of the guide channel is connected with the sewage inlet channel, it can ensure that the sewage is in the third area when the body is in a flat state, so as to be blocked by the main partition, and it can also ensure that the sewage entering from the rear side can flow to the front side through the guide channel, which can avoid the accumulation and collision of sewage. In addition, when the body of the present invention is working at an inclined angle, since the outlet of the guide channel is located in the front area of ​​the top of the upper cover, it can avoid the sewage from flowing back into the outlet.

[0012] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0049] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0052] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0053] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0054] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0055] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0056] The present disclosure provides a cleaning device, which may be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, or other handheld cleaning devices known to those skilled in the art. In an embodiment in which the cleaning device of the present disclosure is a handheld floor scrubber, when a user uses the floor scrubber for cleaning, the user may push the floor scrubber to move on a work surface and clean the work surface.

[0057] The cleaning device disclosed in the present invention includes a body and a floor brush assembly. The body serves as a carrier and is configured to install various functional elements required for the cleaning device. The floor brush assembly is disposed at the bottom of the body and is configured to clean the working surface. The body includes a body and a sewage bucket and a fan assembly disposed on the body. The sewage bucket is used to contain the dirt sucked from the working surface by the cleaning device, and the fan assembly is used to form a negative pressure in the sewage bucket to suck the dirt on the working surface into the sewage bucket. A roller brush and a cleaning liquid tank are provided on the floor brush assembly. The roller brush is configured to clean the working surface, and the cleaning liquid tank is configured to contain cleaning liquid and spray the cleaning liquid onto the roller brush and / or the working surface.

[0058] Since the cleaning liquid tank of the present invention is arranged on the floor brush assembly, the weight of the machine body can be reduced, so that the force required for the user to hold the machine body is smaller, and the convenience of the user pushing and pulling the machine body is improved. In addition, the cleaning liquid tank is arranged on the floor brush assembly, which can effectively increase the downward pressure of the floor brush assembly, thereby improving the cleaning effect of the roller brush on the work surface. The cleaning liquid tank of the present invention can act as a roller brush cover to prevent the splash of sewage generated when the roller brush rotates, saving the number of parts and material costs, and can integrate the pick-up and placement actions of the two structures into one, thereby reducing the number of times the user disassembles and assembles parts, thereby reducing the frequency of user pick-up and placement.

[0059] In one embodiment of the present disclosure, a base station is also provided, which is configured to place a cleaning device, and the cleaning device and the base station together constitute a cleaning system. In order to allow the cleaning device to be stably placed, the base end surface of the base station is configured to be a shape that matches the bottom surface of the cleaning device. The base station can charge the cleaning device, and the cleaning device can also complete self-cleaning operations at the base station, etc. The specific functions are designed according to actual needs.

[0060] In the cleaning device of the present disclosure, the side of the cleaning device facing the user is recorded as the rear side, and the side away from the user is recorded as the front side, including:

[0061] Floor brush assembly;

[0062] The machine body is configured to be able to rotate relative to the brush assembly to make its extension direction parallel to the working surface so as to be in a flat state, and a sewage bucket is arranged at the front side of the machine body;

[0063] The sewage bucket includes a bucket cover and a bucket body, and a sewage inlet channel is arranged in the bucket body. The bucket cover of the sewage bucket is provided with a main partition, an air outlet and a guide channel. The main partition is fitted with the bucket body on opposite sides and extends along the extension direction of the body, dividing the upper part of the inner cavity into a first area located on the front side and a third area located on the rear side. The sewage inlet channel is arranged in the third area, the air outlet is arranged in the first area, and the outlet of the guide channel is constructed to be higher than the main partition when the body is in a lying state, and the inlet of the guide channel is connected with the sewage inlet channel.

[0064] Since the main partition can separate the upper area of ​​the inner cavity into a first area located at the front side and a third area located at the rear side, and the sewage inlet channel is arranged in the third area, and the air outlet is arranged in the first area, the outlet of the guide channel is higher than the main partition when the body is in a flat state, and the inlet of the guide channel is connected to the sewage inlet channel, it can ensure that the sewage is in the third area when the body is in a flat state, so that it is blocked by the main partition, and it can also ensure that the sewage entering from the rear side can flow to the front side through the guide channel, which can avoid the accumulation and collision of sewage. In addition, when the body of the present invention works in a flat state, it is ensured that the dirt can flow out from a position higher than the main partition. When the body of the present invention works at an inclined angle, since the outlet of the guide channel is located in the front area of ​​the top of the upper cover, it can avoid the sewage from flowing back into the outlet. .

[0065] For ease of understanding, refer to Figures 1 to 33 , the specific structure and working principle of the cleaning system of the present disclosure are explained in detail in combination with an embodiment. It should be noted that in order to keep the text concise, the present disclosure introduces the cleaning device 10 and the tray 20 together when describing the specific structure and working principle of the cleaning system, and no longer describes the two separately. It should also be noted that the directional words "front and back" used in this article to describe the structure of the cleaning device 10 are set based on the user, that is, the side of the cleaning device 10 facing the user is recorded as the back side of the cleaning device 10, and the side away from the user is recorded as the front side of the cleaning device 10.

[0066] like Figure 1 As shown, the present disclosure provides a cleaning system, which includes a tray 20 and a cleaning device 10. The cleaning device 10 is used to clean work surfaces such as work surfaces and carpets, and the cleaning device 10 can be docked with the tray 20. For example, the cleaning device 10 can be placed on the tray 20, so that the cleaning device 10 can be charged through the tray 20.

[0067] Specifically, Figure 2 and Figure 3 As shown, the cleaning device 10 at least includes a body 11 and a floor brush assembly 12. Among them, the body 11 includes a body 11 and a sewage bucket 14 arranged on the body 11. The body 11 is used as a carrier and is constructed to be used to install various functional elements required for the cleaning device 10. The floor brush assembly 12 is arranged at the bottom of the body 11 and is configured to clean the work surface. When cleaning the work surface, the floor brush assembly 12 is always attached to the work surface. The floor brush assembly 12 may include a floor brush shell 121 and a roller brush 123 rotatably connected to the floor brush shell 121; the floor brush shell 121 is used to install various components of the floor brush assembly 12, and the roller brush 123 can rotate relative to the work surface to wipe the stains on the work surface. As shown Figure 3As shown, a sewage suction pipe 128 connected to the sewage bucket 14 is provided in the floor brush assembly 12, and a sewage suction port 1281 is formed at the bottom end of the sewage suction pipe 128 at a position adjacent to the roller brush 123 on the floor brush housing 121. A fan assembly 16 is provided on the machine body 11, and the fan assembly 16 can form a negative pressure in the sewage bucket 14, so that the dirt on the working surface can be sucked into the sewage bucket 14 through the sewage suction pipe 128.

[0068] In order to facilitate the user to pull the cleaning device 10, as Figure 2 and Figure 3 As shown, the cleaning device 10 of the present disclosure may be provided with a handheld component 13, which is provided on the body 11 and is used for the user to hold. The user can hold the handheld component 13 and drag the cleaning device 10 on the work surface, so that the floor brush component 12 can clean all parts of the work surface. Among them, the handheld component 13 may include a holding structure in a closed ring shape and a support rod, and the holding structure is connected to the body 11 through the support rod. When using the cleaning device 10, the user only needs to hold the holding structure to drag the cleaning device 10 on the work surface.

[0069] The floor brush assembly 12 is movably connected to the body 11, so that the body 11 can swing relative to the floor brush assembly 12, thereby facilitating the user to drag the cleaning device 10 back and forth. In order to enable the cleaning device 10 of the present disclosure to extend into a low space such as the bottom of a bed or a sofa, and clean the working surface in the low space, such as Figure 4 and Figure 5 As shown, when the floor brush assembly 12 is placed on the work surface, the body 11 of the cleaning device 10 of the present invention can be rotated relative to the floor brush assembly 12 so that its extension direction is parallel to the work surface, that is, the body 11 is in a lying state, so that the body 11 and the floor brush assembly 12 can be almost in a straight line, or the angle between the two is small, thereby allowing the cleaning device 10 of the present invention to extend into low spaces such as the bottom of a bed or a sofa, and clean the work surface in the low space.

[0070] In order to allow at least part of the machine body 11 to extend into areas such as the bottom of a bed or a sofa, it is necessary to control the height dimension of the machine body 11 when lying flat, and the height dimension can also be understood as the thickness in the front-to-back direction of the machine body 11. The cleaning device disclosed in the present invention sets the cleaning liquid tank on the floor brush assembly 12. Compared with the solution in which the cleaning liquid tank and the sewage bucket are set on opposite sides of the machine body 11 in the traditional cleaning device, the overall thickness of the machine body 11 disclosed in the present invention is smaller, which is conducive to extending the entire machine body 11 into areas with lower heights such as the bottom of a bed for cleaning when lying flat.

[0071] In one embodiment of the present disclosure, in a lying state, the highest height of the body 11 of the cleaning device 10 of the present disclosure does not exceed 130 mm. In this way, even if the height of the space under the bed or the bottom of the sofa is low, the cleaning device 10 of the present disclosure can be extended into the low space, thereby effectively expanding the cleaning range of the cleaning device 10 of the present disclosure.

[0072] In one embodiment of the present disclosure, the maximum angle between the body 11 of the present disclosure and the work surface when in a lying state is 0.5°, so that the body 11 of the present disclosure can be in an almost completely lying state, thereby facilitating the body 11 of the present disclosure to extend into a low space with a lower height.

[0073] In one embodiment of the present disclosure, the sewage bucket 14 is disposed on the front side of the machine body 11. Figure 3 , Figure 4 When the machine body 11 is in a flat state, the rear side of the machine body 11 is close to the working surface and is nearly parallel or distributed at a small angle. Therefore, it is sufficient to ensure that the rear side of the machine body 11 extends in a straight line; in addition, the sewage bucket 14 is arranged at the front side of the machine body 11 to prevent the handle or other parts on the sewage bucket 14 from interfering with the ground, causing damage to the parts or interfering with the flatness of the machine body 11.

[0074] The sewage bucket 14 of the present disclosure is used to contain dirt sucked from the working surface, and the dirt can be sewage generated by cleaning, and can also include various garbage sucked from the working surface. Figure 6 As shown, a sewage inlet 141 is provided at the bottom of the sewage bucket 14. When the sewage bucket 14 is installed on the body 11, the sewage inlet 141 is connected to the sewage suction pipe 128. In this way, the dirt on the working surface can enter the sewage bucket 14 in sequence through the sewage suction port 1281 on the floor brush assembly 12, the sewage suction pipe 128 and the sewage inlet 141 of the sewage bucket 14.

[0075] like Figure 8 and Fig. 9 As shown, the sewage bucket 14 includes a barrel body 142 having a sewage inlet channel 1411 and an upper cover 143 for cooperating with the barrel body 142. The barrel body 142 and the upper cover 143 enclose an inner cavity 144 for storing dirt. The sewage inlet channel 1411 forms a sewage inlet port 141 at the rear side of the bottom surface of the sewage bucket 14. Fig. 9 As shown, the fan assembly 16 of the present invention is connected to the inner cavity 144 of the sewage bucket 14 through the air outlet 1431. In this way, during the operation of the fan assembly 16, a negative pressure can be formed in the inner cavity 144 of the sewage bucket 14, thereby sucking the dirt on the working surface into the inner cavity 144 of the sewage bucket 14 along the sewage suction pipe 128 and the sewage inlet channel 1411.

[0076] like Fig.10 and Fig.11As shown, the upper cover 143 is provided with a guide channel 1432, the entrance of which is located above the sewage inlet 141 and is directly connected to the sewage inlet 141 through the sewage inlet channel 1411, and the outlet of the guide channel 1432 is located in the inner cavity 144 of the sewage bucket 14, so that after the dirt enters from the sewage inlet 141, it can enter the inner cavity 144 of the sewage channel along the sewage inlet channel 1411 and the guide channel 1432. Specifically, as Fig.12 As shown, the inlet of the guide channel 1432 is located at the rear side of the sewage bucket 14 , and the outlet of the guide channel 1432 is located at the front side of the sewage bucket 14 .

[0077] like Fig. 9 As shown, in one embodiment of the present disclosure, the guide channel 1432 may be an integral structure with the upper cover 143 , while in another embodiment of the present disclosure, the guide channel 1432 and the upper cover 143 may be provided separately.

[0078] like Fig. 9 and Fig.13 As shown, the sewage bucket 14 of the present disclosure further includes a main partition 1433 extending along the extension direction of the body 11 and a solid-liquid separation frame 1434 extending perpendicularly to the extension direction of the body 11. Fig. 9 In the viewing direction, the main partition 1433 extends in the axial direction of the barrel 142, or is understood to be Fig. 9 The solid-liquid separation frame 1434 extends in the radial direction of the barrel 142, or is understood to be in the approximate height direction shown; Fig. 9 The solid-liquid separation frame 1434 is arranged in the inner cavity 144, and its edge is in contact with the barrel body 142, thereby dividing the inner cavity 144 into an upper area and a lower area in the axial direction of the barrel body 142. The main partition 1433 is located in the upper area, and its two opposite sides are in contact with the barrel body 142, thereby dividing the upper area of ​​the inner cavity 144 into a front area and a rear area. In this way, Figure 8 As shown, the main partition 1433 and the solid-liquid separation frame 1434 can divide the inner cavity 144 into a first area, a second area, a third area, and a fourth area. Among them, the first area is the front side area ( Figure 8 The third area is the rear side area divided by the main partition 1433 in the upper area ( Figure 8 The lower part of the area divided by the solid-liquid separation frame 1434 is the second area ( Figure 8 The portion corresponding to the C region is the fourth region ( Figure 8 As shown in D area). Fig.10As shown, the sewage bucket 14 of the present disclosure further includes a partition plate 1435, which is fixedly disposed on the main partition plate 1433 and is configured to extend radially from the end surface of the main partition plate 1433 toward the barrel body 142 and fit with the front side wall of the barrel body 142. In the axial direction, the partition plate 1435 extends from the top of the upper cover 143 toward the solid-liquid separation frame 1434, and there is a height difference between the bottom of the partition plate 1435 and the solid-liquid separation frame 1434, forming a certain interval, wherein the length of the partition plate 1435 extending from the upper cover 143 to the solid-liquid separation frame 1434 is 70% to 80% of the distance between the upper cover 143 and the solid-liquid separation frame 1434. In this embodiment, the length of the partition plate 1435 extending from the upper cover 143 to the solid-liquid separation frame 1434 accounts for 70% of the distance between the upper cover 143 and the solid-liquid separation frame 1434. In a specific embodiment of the present disclosure, the end surface of the partition plate 1435 is perpendicular to the end surface of the main partition plate 1433, or is arranged at other angles.

[0079] Thus, the partition plate 1435 and its bottom edge can separate the first area ( Figure 8 The A area shown in the figure is divided into the first sub-area, the second sub-area and the third sub-area ( Fig.10 As shown in the A3 area). Fig.10 As shown, the first sub-area is the area enclosed by the left side of the partition plate 1435 ( Fig.10 The second sub-area is the area enclosed by the right side of the partition plate 1435 ( Fig.10 The third sub-region is the region between the lower edge of the partition plate 1435 and the solid-liquid separation frame 1434 ( Fig.10 A3 area shown).

[0080] The inlet and outlet of the diversion channel 1432 of the present disclosure are separated by the main partition 1433. Specifically, the inlet of the diversion channel 1432 is located in the top area of ​​the upper cover 143 and is located according to Figure 8 The outlet of the guide channel 1432 is located in the top area of ​​the upper cover 143, and is located according to Fig.10The A1 area shown. The inlet and outlet of the diversion channel 1432 are separated by the main partition 1433 on the front and rear sides of the inner cavity 144. The sewage inlet channel 1411 of the barrel body 142 is correspondingly set in the rear area of ​​the inner cavity 144, and is constructed to extend upward from the sewage inlet 141 at the bottom of the barrel body 142 to the inlet of the diversion channel 1432. This allows the sewage entering from the rear side to flow to the front side of the inner cavity 144 through the diversion channel 1432, and flow downward along the A1 area after flowing out from the outlet. The outlet of the diversion channel 1432 is set in the front area of ​​the inner cavity 144 and separated from the inlet of the diversion channel 1432, which can avoid the accumulation and collision of sewage. In addition, when the body 11 of the present disclosure is working at an inclined angle, since the outlet of the diversion channel 1432 is located in the front area of ​​the top of the upper cover 143, it can prevent sewage from flowing back into the outlet.

[0081] like Fig.13 As shown, the main partition 1433 is in the shape of a plate as a whole, and a separation hole 14344 is provided on the solid-liquid separation frame 1434. Figure 3 The body 11 is placed vertically in the direction shown, or when working, it is tilted at a certain angle relative to the working surface, or Figure 4 and Figure 5 When lying flat in the direction shown, after the dirt flows out from the outlet of the guide channel 1432, it can pass through the solid-liquid separation frame 1434 to reach the B area and the D area below the solid-liquid separation frame 1434, so that the solid waste with larger particles in the dirt can be retained on the solid-liquid separation frame 1434, so that it is convenient for the user to subsequently remove the upper cover 143 from the barrel body 142, clean the solid-liquid separation frame 1434, and remove the solid waste on the solid-liquid separation frame 1434.

[0082] Continue to refer Fig.13 In the sewage bucket 14 of the present disclosure, the main partition 1433 extends along the axial direction of the sewage bucket 14 toward the solid-liquid separation frame 1434, and a water discharge gap 1436 is provided between the main partition 1433 and the solid-liquid separation frame 1434. When the body 11 is in a tilted state, after the dirt flows out from the outlet of the guide channel 1432, it flows downward along the main partition 1433 and continues to flow downward through the water discharge gap 1436, thereby preventing the dirt from accumulating between the main partition 1433 and the solid-liquid separation frame 1434.

[0083] The air outlet 1431 is arranged at the top area of ​​the upper cover 143, and is located in the A2 area surrounded by the partition plate 1435, the main partition plate 1433 and the barrel body 142, that is, the air outlet 1431 and the outlet of the guide channel 1432 are separated by the partition plate 1435. This allows the fan assembly 16 to form a negative pressure in the inner cavity 144 through the air outlet 1431. When the dirt flows out from the outlet of the guide channel 1432, it can flow downward to the solid-liquid separation frame 1434 under the action of gravity and the negative pressure formed by the airflow, and the solid garbage with larger particles in the dirt can be trapped on the solid-liquid separation frame 1434, and the remaining sewage will fall into the B area and the D area below the solid-liquid separation frame 1434.

[0084] When it is necessary to clean a lower area such as the bottom of a sofa or a bed, the body 11 of the cleaning device 10 needs to be raised. Figure 5 The machine body 11 is laid flat in the manner shown. When the machine body 11 is in the laid flat state, the air outlet 1431 is still located in the upper area of ​​the inner cavity 144, so that the fan assembly 16 can form a negative pressure in the inner cavity 144 through the air outlet 1431. After the dirt flows out from the outlet of the guide channel 1432, it can continue to flow through the solid-liquid separation frame 1434 under the action of the negative pressure formed by gravity and airflow. It should be noted here that since the machine body 11 changes from a vertical or inclined state to a laid flat state, the area B located in front of the area D will be located above the inner cavity 144 like the area A, while the areas C and D are located below the inner cavity 144 at this time, so the sewage in the inner cavity 144 will be retained in the area closer to the rear side of the inner cavity 144, that is, it will be retained in the areas C and D of the main partition 1433.

[0085] In the lying state, at least part of the dirt flowing out of the outlet of the guide channel 1432 will flow along the end surface of the main partition 1433 toward the solid-liquid separation frame 1434. In order to facilitate the smooth flow of dirt when the body 11 is lying flat, in one embodiment of the present disclosure, when the body 11 is in the lying state, the end surface of the main partition 1433 is constructed as an inclined surface, that is, from the outlet of the guide channel 1432 to the solid-liquid separation frame 1434, the end surface of the main partition 1433 is constructed to gradually tilt downward. The inclination can be achieved by setting the end surface of the main partition 1433 as an inclined surface, or it can be that when the body 11 is lying flat, the body 11 and the working surface will still be inclined at a small angle, so that the end surface of the main partition 1433 is in an inclined state. The inclination angle between the body 11 and the working surface does not affect the body 11 from entering the low-level cleaning area, and the present disclosure will not list them one by one here.

[0086] It can be understood that when the body 11 of the present invention is tilted at a small angle for cleaning, the available sewage storage space in the inner cavity 144 of the sewage bucket 14 of the present invention is part of the B area, part of the C area and the D area. The principle is similar to the first two cases and will not be repeated here.

[0087] It should be noted that when the body 11 is in a lying position, when the sewage flows out from the outlet of the guide channel 1432 and flows along the end surface of the main partition 1433 toward the solid-liquid separation frame 1434, under the action of the negative pressure of the air outlet 1431, part of the sewage may bypass the edge of the partition 1435 and flow to the A2 area, that is, the sewage flows from the A1 area to the A3 area and then flows to the A2 area. However, since the air outlet 1431 is located at the upper part of the A2 area, the sewage will not be sucked into the air outlet 1431, that is, the sewage will be located at the lower part of the A2 area under the action of gravity and will not be sucked into the fan assembly 16. From another perspective, there is a safety zone between the air outlet 1431 and the end surface of the main partition 1433, refer to Fig.10 The A4 area shown in the figure, this safety zone ensures that the negative pressure formed at the air outlet 1431 cannot suck in the sewage in the A2 area. When the body 11 is in a flat state, the air outlet 1431 is located above the end surface of the main partition 1433; when the body 11 is in a vertical state, the air outlet 1431 is located in front of the end surface of the main partition 1433. In addition, the distance between the air outlet 1431 and the end surface of the main partition 1433 needs to be ensured to avoid the failure to form a safety zone due to the distance being too small.

[0088] Specifically, as mentioned above, in one embodiment of the present disclosure, the length of the partition plate 1435 extending from the upper cover 143 to the solid-liquid separation frame 1434 is 70% to 80% of the distance between the upper cover 143 and the solid-liquid separation frame 1434, so the length of the A2 area in the vertical direction accounts for 70% to 80% of the total length of A2 and A3, so that an effective safety zone can be formed to ensure that the negative pressure formed at the air outlet 1431 cannot suck the sewage in the A2 area. In one embodiment of the present disclosure, when the body 11 is in a normal tilted state, the sewage cannot enter the air outlet 1431 under the action of suction because the air outlet 1431 is far from the surface of the sewage; but when the body 11 is in a flat state, it can also be ensured that the sewage will not enter the air outlet 1431 by reducing the negative pressure at the air outlet 1431, that is, reducing the power of the fan assembly 16. For example, in a normal working state, the fan assembly 16 can work at different powers and be adjusted according to the user's choice. However, when the body 11 is in a flat state, the fan assembly 16 is only allowed to work in a lower power mode, for example, by using the Hall sensor and the magnet to identify whether the body is in a flat state. For example, when it is detected that the body 11 is in a flat state, the control unit can automatically switch to control the fan assembly 16 to work in a low power mode. It should be noted that the cleaning device of the present disclosure sets a safety zone in the A2 area, so the low power is relative to the normal power of the cleaning device of the present disclosure. The low power mode can still be equivalent to the normal power of the traditional cleaning device, and can even be greater than the normal power of the cleaning device to ensure that the dirt can enter the sewage bucket.

[0089] In the cleaning device disclosed in the present invention, when the body 11 is switched between the vertical state, the inclined state, and the lying state, the sewage stored in the sewage bucket inner cavity 144 will be retained in different areas. For example, when the body 11 is in the vertical state, the sewage will be retained in the following areas: Figure 8 When the machine body 11 is in a flat position, the sewage will be stored in the D area and the B area. Figure 8 The D area and the C area shown in the figure, at this time, part of the space in the D area is common. In one embodiment of the present disclosure, the sum of the volumes of the C area and the D area can be smaller than the sum of the volumes of the A area and the C area, and the sum of the volumes of the A area and the C area can be smaller than the sum of the volumes of the B area and the D area. In this way, the sewage storage requirements of the cleaning device 10 in various states can be effectively met, and the overall volume of the sewage bucket 14 will not be too large.

[0090] like Fig.12As shown, in one embodiment of the present disclosure, the inlet of the guide channel 1432 can be located at the center of the rear side of the inner cavity, the front half of the guide channel 1432 is constructed as an inclined channel extending obliquely from the inlet to the front side, and the rear half is a straight channel, that is, the outlet of the guide channel 1432 is constructed to face the front side wall of the sewage bucket 14, approximately perpendicular to the end face of the main partition 1433, so that the flow direction of the sewage flowing out of the outlet of the guide channel 1432 is roughly the same as the airflow direction, thereby avoiding the airflow leaving the outlet together with the sewage from rotating and interfering with the sewage, and reducing the noise caused by the sewage flowing out of the guide channel 1432 due to the airflow disturbance. In this way, after the sewage flowing into the guide channel 1432 hits the front wall of the sewage bucket 14, it flows from the opening of the guide channel 1432 to the inner cavity 144 of the sewage bucket 14. The noise generated by the sewage bucket 14 in this embodiment is relatively small, which can effectively improve the user experience.

[0091] And as Fig.14 As shown, in another embodiment of the present disclosure, the inlet of the guide channel 1432 can be located at the center of the rear side of the inner cavity, the front half of the guide channel 1432 is constructed as an inclined channel extending obliquely from the inlet to the front side, and the rear half is a straight channel, and the end of the straight channel is arc-shaped, so that the opening of the guide channel 1432 faces the direction away from the partition plate 1435. In this way, the sewage flowing into the guide channel 1432 can flow out from the side opening of the guide channel 1432 along the arc-shaped end of the end of the guide channel 1432, and flow into the inner cavity 144 of the sewage bucket 14 after impacting the side wall of the sewage bucket 14. In this embodiment, the sewage flowing out of the guide channel 1432 in the sewage bucket 14 impacts the side wall away from the air outlet 1431, so that most of the sewage flows down along the side wall away from the air outlet 1431, which can reduce the possibility of water droplets mixing in the air flow and flowing into the fan assembly 16 from the air outlet 1431.

[0092] In the above two embodiments, the direction of the dirt flowing out from the outlet of the guide channel 1432 is perpendicular to the extension direction of the sewage bucket 14 rather than parallel to the extension direction of the sewage bucket 14. In this way, when the cleaning device 10 of the present invention is placed in a vertical or inclined state, the dirt flowing out from the outlet flows in a roughly parabolic direction rather than directly flowing downward in the vertical direction due to the influence of gravity, thereby reducing the degree to which gravity increases the speed of the dirt flow, and can effectively reduce the initial speed of the dirt flowing from the outlet of the guide channel 1432 to the bottom of the sewage bucket 14, thereby reducing the collision force between the dirt and the solid-liquid separation frame 1434, and reducing the large amount of water droplets splashed by the splashes generated by the collision force between the dirt and the solid-liquid separation frame 1434; further, it can avoid that some water droplets splashed due to the strong collision are mixed in the air flow and flow into the fan assembly 16 from the air outlet 1431, causing the fan assembly 16 to fail to work normally, thereby ensuring that the fan assembly 16 of the present invention can work normally and extending the service life of the fan assembly 16.

[0093] In addition, since the air outlet 1431 is disposed in the top area of ​​the upper cover, a height difference can be formed between the air outlet 1431 and the lower end of the partition plate 1435, so that a safety zone in a vertical state is formed below the A2 area. Fig.10 When the airflow mixed with water droplets moves upward in the A3 area, the water droplets therein can collide with the main partition 1433, the partition plate 1435 or the inner wall of the barrel body 142 of the sewage barrel 14 at the lower part of the A3 area or the A2 area under the action of gravity and airflow suction, and will not be suspended in the A3 area or the A2 area, thereby minimizing the water droplets from entering the air outlet 1431.

[0094] Moreover, if Figure 8 and Fig.10 As shown, in one embodiment of the present disclosure, there is a gap between the partition plate 1435 and the solid-liquid separation frame 1434, and the gap connects the A1 area and the A2 area. The partition plate 1435 is arranged on the left side of the center line of the main partition plate 1433, which makes the lower end opening of the A2 area (the gap between the partition plate 1435 and the solid-liquid separation frame 1434) have a large air outlet area, the air outlet 1431 has a small air outlet area, and the height of the A2 area is relatively large, so that even if the sewage in the inner cavity 144 of the sewage bucket 14 is driven by the airflow to move toward the air outlet 1431, it can stay in the safe area and will not be sucked into the air outlet 1431.

[0095] like Fig. 9As shown, in one embodiment of the present disclosure, the solid-liquid separation frame 1434 includes a front separation area 14341, a middle partition area 14342, and a rear separation area 14343. Separation holes 14344 are provided on the front separation area 14341 and the rear separation area 14343, so that dirt can flow downward through the separation holes 14344. The middle partition area 14342 is not provided with separation holes 14344.

[0096] like Fig.13 As shown, the main partition 1433 forms the above-mentioned drainage gap 1436 along the position corresponding to the middle partition area 14342, that is, the position between the lower end of the main partition 1433 and the middle partition area 14342. In the flat state, when the machine body 11 is pushed and pulled, the sewage in the C area and the D area will fluctuate to a large extent, and these fluctuating sewage cannot pass through the middle partition area 14342 to flow to the A1 area and the A2 area, thereby preventing the sewage from being brought into the air outlet 1431 when fluctuating. In addition, when the sewage flows to the lower end along the main partition 1433, part of the sewage will flow downward through the separation hole 14344 of the front separation area 14341, and part of the sewage will flow through the drainage gap 1436 and flow downward through the separation hole 14344 of the rear separation area 14343.

[0097] When the body 11 is in a lying state, the sewage at the connection position between the main partition 1433 and the middle partition area 14342 in the A3 area can directly enter the C area from the sewage gap 1436, thereby preventing the sewage from remaining in the A3 area or in the sewage gap 1436 when the body 11 is in a lying state.

[0098] In order to control the amount of sewage directly entering the C region from the drainage gap 1436, in one embodiment of the present disclosure, the width of the drainage gap 1436 of the present disclosure is 1 mm to 3 mm. When the width of the drainage gap 1436 is 1 mm to 3 mm, the sewage at the connection position between the main partition 1433 and the middle partition area 14342 in the A3 region can be directly entered into the C region from the drainage gap 1436, so as to avoid the sewage remaining in the A3 region when the machine body 11 is in a flat state, and to prevent the sewage from entering the A2 region under the action of the airflow and then being sucked into the air outlet 1431. At the same time, when the machine body 11 is in a flat state, the fluctuating water surface will splash water when it contacts the middle partition area 14342 and enter the A region and / or the B region through the drainage gap 1436 under the action of pushing and pulling the machine body 11. However, by controlling the width of the drainage gap 1436, the range of sewage splashing through the drainage gap 1436 can be controlled, and even if the sewage splashes out from the drainage gap 1436, it will not enter the A2 region. Furthermore, in one embodiment of the present disclosure, the width of the water discharge gap 1436 of the present disclosure is 1.5 mm, which can achieve rapid discharge of sewage accumulated in area A while ensuring that water splashed by water surface fluctuations during the back-and-forth dragging process will not enter area A2.

[0099] When the machine body 11 is in a vertical or tilted state, when a large amount of dirt enters the inner cavity 144 of the sewage bucket 14 through the flow guide channel 1432, in order to reduce the residence time of the sewage on the solid-liquid separation frame 1434, Figure 3 and Figure 8 As shown, in one embodiment of the present disclosure, a gap is formed between the front side of the solid-liquid separation frame 1434 of the present disclosure and the barrel body 142, so that excess sewage falling onto the solid-liquid separation frame 1434 can flow from the gap between the front side of the solid-liquid separation frame 1434 and the barrel body 142 to the bottom of the solid-liquid separation frame 1434, thereby reducing the residence time of the sewage on the solid-liquid separation frame 1434 and preventing the sewage from being sucked into the air outlet 1431 under the action of the airflow.

[0100] like Figure 8 and Fig. 9As shown, the sewage bucket 14 of the present disclosure further includes a water full detection probe 1437, and probe accommodating parts 1438 are provided on both sides of the upper cover 143. The probe accommodating parts 1438 extend downward from the top area of ​​the upper cover 143 along both sides of the main partition 1433. The probe accommodating parts 1438 have an open probe groove 14381, and the probe groove 14381 can be, for example, a structure similar to a U-shaped groove. When the two probe accommodating parts 1438 are respectively attached to the inner wall of the barrel body 142 at the corresponding position, a closed probe groove 14381 is formed between the probe accommodating parts 1438 and the barrel body 142 of the sewage bucket 14, and the two water full detection probes 1437 are respectively arranged in the lower end openings of the two probe grooves 14381, and the whole is arranged along the extension direction of the sewage bucket 14. In this way, during the use of the cleaning device 10 of the present invention, when the two water full detection probes 1437 are both soaked with sewage and a conductive circuit can be formed between the two in the sewage bucket 14, the water full detection probes 1437 can be turned on to trigger a water full signal. The cleaning device 10 of the present invention can stop working in time according to the water full signal to avoid excessive sewage in the sewage bucket 14, overflow or sewage being sucked into the fan assembly 16, etc.

[0101] Furthermore, since the detection ends of the two water full detection probes 1437 are respectively arranged in the lower openings of the two probe grooves 14381, it is possible to avoid false alarms caused by the water full detection probes 1437 when a large amount of sewage falls from the solid-liquid separation frame 1434. When the upper cover 143 is removed from the barrel body 142, the probe grooves 14381 of the accommodating portion 1438 are in an open state as a whole, so that it is convenient for users to clean the probe grooves 14381, and avoid residual dirt in the probe grooves 14381 causing abnormal operation of the water full detection probes 1437.

[0102] It is understandable that, since the water level lines when the sewage bucket is full of water are different when the machine body 11 is in the vertical, inclined, and lying states, and the water level lines in the three states have a rough intersection area, ideally, the three water level lines have a common intersection, and it is only necessary to make the detection end of the water full detection probe 1437 located at the common intersection, so that the water fullness in the three states can be detected through one detection point. However, in practice, it is difficult for the three lines to have a common intersection, and it is also difficult to ensure that the detection end of the water full detection probe 1437 is located at the common intersection position. Even if there is such a common intersection, it is difficult to ensure that the sewage bucket has a suitable sewage storage volume and different sewage volumes in the three states under the intersection setting to ensure space utilization.

[0103] Therefore, if Figure 8 , Fig. 9As shown, in one embodiment of the present disclosure, the probe accommodating portion 1438 and the water full detection probe 1437 of the present disclosure are configured to extend downward by a set distance relative to the solid-liquid separation frame 1434. Specifically, the opposite sides of the solid-liquid separation frame 1434 are configured to extend downward to form a sinking area 14345, and the upper end surface of the sinking area 14345 is lower than the upper end surface of other areas of the solid-liquid separation frame 1434. The bottom of the probe accommodating portion 1438 is constructed to extend downward to cooperate with the sinking area 14345, so that the detection end of the water full detection probe 1437 can be lower than the end face of the solid-liquid separation frame 1434, that is, lower than the end faces of the front separation area 14341, the middle partition area 14342 and the rear separation area 14343, so that the detection end of the water full detection probe 1437 can be triggered before the sewage reaches the front separation area 14341, the middle partition area 14342 and the rear separation area 14343, thereby ensuring the early triggering of the dirty and sewage being full.

[0104] Moreover, if Fig. 9 As shown, in the sinking area 14345, the area directly below the probe groove 14381 is a partition surface, and there is no separation hole 14344 for water to pass through, so that when the body 11 of the present invention is in a lying state or a nearly lying state, the partition surface of the sinking area 14345 can withstand the fluctuation of the sewage below, avoiding the water full detection probe 1437 from making a false alarm when the sewage is not full.

[0105] like Figure 8 and Fig.33 As shown, in one embodiment of the present disclosure, area A is close to the air outlet, and the gas flow rate is relatively large, while area C is far away from the air outlet, and the gas flow rate is relatively small. According to the Bernoulli principle, a pressure difference is formed between area A and area C. Therefore, there is a suction force from area C to area A in the probe end area. When the machine body is in an inclined state and the sewage water level line reaches area C and is located below the end of the probe without contact and conduction, there is a gap between the bottom surface of the probe groove and the sinking area 14345. The suction force from area C to area A brings the sewage into the probe in the probe groove through the aforementioned gap and achieves conduction. In this way, when the sewage reaches the sinking area but does not immerse the solid-liquid separation frame 1434, the water full detection probe 1437 can be triggered in advance to ensure the accuracy of the water full detection. When the machine body 11 is placed in a vertical state or horizontally, the sewage water level line gradually rises into the probe groove to contact and conduct with the probe. Through the above settings, this embodiment can realize water fullness detection in three states through a pair of probes, and can ensure that the volumes of the three areas B, C, and D account for a larger proportion of the overall sewage barrel volume, while balancing the sewage volume in the three states, thereby ensuring the utilization rate of the sewage storage space in the sewage barrel.

[0106] In the above embodiment, the edge of the probe accommodating portion 1438 and the edge of the sinking area 14345 are not in contact, and there is a certain gap between the two, which can be, for example, 1.5 mm, so that sewage can enter the probe groove 14381. At the same time, the ability of sewage to climb in the probe accommodating portion 1438 area can be improved, thereby ensuring the accuracy of sewage detection. In particular, when the body 11 changes from a vertical or inclined state to a lying state, the water level in the sewage bucket will change. Through the above structural design, no matter what state the body 11 is in, the total amount of sewage during the water full detection can be kept as consistent as possible. Even if the water level changes under different states, as long as the sewage in the sewage bucket reaches the vicinity of the solid-liquid separation frame, the water full detection probe 1437 can be triggered through air connection, thereby avoiding the risk of excessive water level when the body 11 switches between different states.

[0107] And as Fig. 9 , 15 As shown, in another embodiment of the present disclosure, the detection end of the water full detection probe 1437 is constructed to be bent at a preset angle toward the front side of the sewage bucket 14, and the water full detection probe 1437 is constructed to determine the water fullness of the sewage bucket 14 by whether the end M of the water full detection probe 1437 is soaked with sewage when the body 11 is in a vertical state or placed at a small tilt angle; when the body 11 is placed in a lying state, the water fullness of the sewage bucket 14 is determined by whether the bending point N of the water full detection probe 1437 is soaked with sewage; when the body is in a normal tilted state, the water fullness of the sewage bucket 14 is determined by whether any position of the line from the bending point N to the end M on the water full detection probe 1437 is soaked with sewage. In this way, the water full detection probe 1437 disclosed in the present invention can effectively ensure the water full detection accuracy when the body 11 is in various postures by only setting a water full detection probe 1437 on each side. There is no need to set multiple water full detection probes 1437 according to different situations. While the structure is simple, it can also ensure the sewage volume utilization rate in the sewage bucket.

[0108] The detection end of the water full detection probe 1437 is constructed as a structure that is bent toward the front side of the sewage bucket at a preset angle, and different positions of the detection end can be used as detection points to adapt to water full detection of different water levels in different placement states. For example, when the body 11 is in a vertical state, the water level line is located in the radial direction of the sewage bucket, when the body 11 is in an inclined state, the water level line is inclined at a certain angle; when the body 11 is in a lying state, the water level line is located in the axial direction of the sewage bucket. It can be understood that the water levels in the three states form a triangular area, and the detection end of the water full detection probe 1437 is designed to be in an inclined state, which can simultaneously adapt to water full detection of sewage volumes in different states.

[0109] In another embodiment of the present disclosure, the water full detection probe 1437 of the present disclosure is constructed with the end thereof being in an arc shape toward the front side of the sewage bucket 14. The principle is similar to that of the aforementioned embodiment and will not be repeated here.

[0110] like Fig. 9 As shown, the sewage bucket 14 of the present disclosure further includes an upper cover 145, which is installed above the upper cover 143. Fig. 9 As shown, in one embodiment of the present disclosure, a filter assembly 1451 is provided on the upper cover 143 of the present disclosure, and the filter assembly 1451 is used to filter out garbage particles in the airflow and absorb water vapor in the airflow, further ensuring that the fan assembly 16 can work normally.

[0111] In one embodiment of the present disclosure, the sewage bucket 14 is detachably mounted on the machine body 11, so that when the user finishes cleaning the work surface, the sewage bucket 14 can be removed from the machine body 11, the dirt in the sewage bucket 14 can be poured out, and the inside of the sewage bucket 14 can be cleaned. Figure 7 A mounting groove 111 is provided on the front side of the body 11, and the mounting groove 111 has a size and shape that matches the sewage bucket 14, so as to be used to install the sewage bucket 14. Specifically, a bearing portion 112 is provided at the bottom of the mounting groove 111, and the bearing portion 112 is used to bear the weight of the sewage bucket 14 when the body 11 is placed vertically or tilted.

[0112] like Figure 7 As shown, the sewage suction pipe 128 extends from the position of the sewage inlet 141 on the floor brush assembly to the body 11, and forms a docking port for docking with the sewage bucket 14 on the bearing portion 112. When the sewage bucket 14 is assembled in the mounting groove 111, the docking port can be docked with the sewage inlet 141 of the sewage inlet channel 1411 on the sewage bucket 14. During the process of disassembling and assembling the sewage bucket 14, some dirt may flow from the docking port or the position of the sewage inlet 141 to the bearing portion 112.

[0113] To this end, in one embodiment of the present disclosure, a drain port 113 is provided on the bearing portion 112, and the drain port 113 penetrates the bearing portion 112. When part of the sewage flows out of the sewage bucket 14 to the bearing portion 112, the part of the sewage can flow downward from the drain port 113 to prevent the sewage from remaining in the bearing portion 112.

[0114] Specifically, Figure 7As shown, in one embodiment of the present disclosure, a drain port 113 is provided on the front side of the bearing portion 112. When the body 11 is in a vertical state, the body 11 will tilt forward at a certain angle relative to the working surface. At this time, the sewage in the bearing portion 112 will flow to the front side and flow out from the drain port 113 on the front side. A drain port 113 is provided on the rear side of the bearing portion 112. Two drain ports 113 at this position can be provided, and the two drain ports are located on the rear side and on both sides of the docking interface. When the bearing portion 112 tilts backward relative to the working surface in the working state, at this time, the sewage in the bearing portion 112 will flow to the rear side and flow out from the drain port 113 on the rear side.

[0115] like Figure 7 As shown, in one embodiment of the present disclosure, the angle S between the bearing portion 112 of the present disclosure and the bottom surface of the mounting groove 111 is at a right angle, and the drain port 113 located at the rear side of the body 11 is located at the angle S between the bearing portion 112 and the bottom surface of the mounting groove 111. In this way, when the body 11 of the present disclosure is tilted backward, the sewage in the bearing portion 112 can be collected at the angle S, and then discharged from the drain port 113 at the angle S.

[0116] In the mounting groove 111 of the present disclosure, the bearing portion 112 is located at the bottom, and the side wall of the machine body 11 forms the side wall of the mounting groove 111, and the bearing portion 112 and the side wall of the machine body 11 are L-shaped. In one embodiment of the present disclosure, the end face of the bearing portion 112 gradually tilts downward from the outside to the machine body 11, so that the angle between the bearing portion 112 and the side wall of the machine body 11 is an acute angle. With such a structural design, no matter the machine body 11 is in a vertical state, an inclined state or a lying state, the sewage on the bearing portion 112 will flow to the rear side to the connection position between the bearing portion 112 and the machine body 11. In this embodiment, the drain port 113 can be set only on the rear side of the bearing portion 112, and no matter what posture the machine body is in, the sewage in the bearing portion 112 will flow out from the drain port 113 on the rear side. In other embodiments, the angle between the bearing portion 112 and the side wall of the machine body 11 can be an obtuse angle, a right angle, etc., which will not be described in detail in the present disclosure.

[0117] Conventional handles without water tanks are designed with concave or convex structures. The convex shape is not only unsightly but also increases the overall height of the machine when lying flat, making it difficult to reach into the space for cleaning when lying flat. The inner top surface of the concave shape is provided with a handle space for fingers to reach in, but in this case the degree of concavity is relatively large, which reduces the volume of the recycling bin. Figure 8As shown, in one embodiment of the present disclosure, in order to facilitate the user to take and place the sewage bucket 14, a handle 146 is provided on the front side of the sewage bucket 14 of the present disclosure. In the unstressed state, the handle 146 can fit the surface of the sewage bucket 14, thereby effectively reducing the overall height of the body 11 in the flat state, saving the occupied space, and increasing the volume of the inner cavity 144 of the sewage bucket 14. In the stressed state, the handle 146 can deflect outward relative to the sewage bucket 14, thereby forming a handle space for the user's fingers to extend into, so that the user can take the sewage bucket 14 out of the installation groove 111.

[0118] Specifically, a hand-gripping structure 1452 is provided on the front side of the upper cover 145 of the present invention. When the user needs to take out the sewage bucket 14, the user can grip the thumb tightly into the hand-gripping structure 1452 of the upper cover 145, and use the remaining four fingers to turn the handle 146 outward and grip it tightly under the handle 146, so that the user can take the sewage bucket 14 out of the mounting groove 111 with one hand.

[0119] When the machine body 11 is in a flat state, in order to facilitate the user to push and pull the machine body 11 for cleaning operations, such as Fig.16 and Fig.17 As shown, a support structure 116 is provided on the rear side of the body 11 of the present invention, and the support structure 116 is configured to be able to contact the work surface when the body 11 is in a lying state, and to support the body 11 on the work surface together with the floor brush assembly 12, so as to maintain a distance between the body 11 and the work surface, and to facilitate the user to push and pull the body 11 back and forth on the work surface to achieve cleaning operations in the lying state.

[0120] Specifically, in one embodiment of the present disclosure, the support structure 116 is a protruding structure protruding outward from the rear side of the body 11. The protruding structure can be made of a material with low friction, such as soft rubber or other plastics with a certain hardness, so as to reduce the friction between it and the working surface. Fig.16 and Fig.17 As shown, in another embodiment of the present disclosure, the support structure 116 is a universal wheel 15, which can roll on the work surface, not only reducing the friction between the work surface and the cleaning device 10, but also facilitating the cleaning device 10 to change the direction of movement on the work surface.

[0121] like Fig.18As shown, in one embodiment of the present disclosure, the universal wheel 15 may include a wheel body 151, a wheel axle 152, a wheel frame 153, a thrust bearing 157, a sleeve 154 and a clamping structure 155. The wheel body 151 is rotatably arranged on the wheel frame 153 through the wheel axle 152. A thrust bearing 157 is arranged between the wheel frame 153 and the sleeve 154, so that the wheel frame 153 and the sleeve 154 can rotate in a horizontal plane through the thrust bearing 157. The end of the wheel frame 153 is clamped on the machine body 11 through the clamping structure 155 to limit the movement of the wheel frame 153 in the vertical direction. In a specific embodiment of the present disclosure, the universal wheel 15 is fixed to the handheld component 13 through the clamping structure 155 and the sleeve 154. In this way, by arranging the thrust bearing 157 in the universal wheel 15, the pressure bearing capacity of the universal wheel 15 can be effectively improved.

[0122] And as Fig.19 and Fig. 20 As shown, in another embodiment of the present disclosure, the universal wheel 15 may include a wheel body 151, a wheel axle 152, a wheel frame 153, a ball bearing 156, a sleeve 154 and a clamping structure 155. The wheel body 151 is rotatably arranged on the wheel frame 153 through the wheel axle 152, and the wheel frame 153 is sleeved with a ball bearing 156. The universal wheel 15 is fixed to the handheld component 13 through the clamping structure 155. Fig.18 The universal wheel 15 shown, Fig.19 The universal wheel 15 shown has a slightly poor pressure bearing capacity, but the structural cost is low. Fig.18 and Fig.19 As shown, the above-mentioned clamping structure 155 can be a clamping ring or a screw with a washer, which is not limited here.

[0123] like Fig.21 , Fig. 22 and Fig.23 As shown, in one embodiment of the present disclosure, the floor brush assembly 12 of the present disclosure includes a floor brush housing 121, a floor brush wheel 122, a roller brush 123 and a cleaning liquid tank 124, wherein the floor brush wheel 122 is used to support the floor brush assembly 12 on the work surface, the roller brush 123 and the cleaning liquid tank 124 are both installed on the floor brush housing 121, the roller brush 123 is used to rotate relative to the work surface to clean the work surface, and the cleaning liquid tank 124 is constructed to contain cleaning liquid and spray the cleaning liquid onto the roller brush 123 and / or the work surface. The cleaning liquid can be water, or it can be a special cleaning liquid for cleaning the work surface or carpet containing cleaning substances, etc.

[0124] like Fig.16As shown, in one embodiment of the present disclosure, the floor brush wheel 122 of the present disclosure includes two first rollers 1221 disposed on the front side of the floor brush housing 121 and two second rollers 1222 disposed on the rear side of the floor brush housing 121. The two first rollers 1221 and the two second rollers 1222 support the floor brush assembly 12 on the work surface. In other embodiments, the first roller 1221 may not be provided, and the floor brush assembly may be supported on the work surface only by the two second rollers 1222 on the rear side and the roller brush 123.

[0125] like Fig.16 As shown, since the body 11 is rotatably connected to the rear side of the floor brush assembly 12, in one embodiment of the present disclosure, the wheel diameter of the second roller 1222 is larger than the wheel diameter of the first roller 1221. In this way, the pressure-bearing capacity of the second roller 1222 can be increased, so that the second roller 1222 can effectively withstand the gravity of the body 11 and the handheld assembly 13.

[0126] Furthermore, in one embodiment of the present disclosure, the second roller 1222 is a universal wheel 15. In this way, when the floor brush assembly 12 swings in the left and right directions, the second roller 1222 can change direction in time and roll relative to the working surface, thereby effectively reducing the torque required for the user to twist the cleaning device 10, making it easier for the user to twist and push the cleaning device 10 of the present disclosure, and when the body 11 is in a flat state, the second roller 1222 provided on the support structure 116 on the body 11 and the floor brush housing 121 can facilitate the user to operate the cleaning device for cleaning operations, whether working in a normal tilted state or in a flat state. At the same time, the support structure 116 on the body 11 serves as the third fulcrum of support, which can ensure the stability of the entire machine when it is lying flat.

[0127] like Fig.29 As shown, in one embodiment of the present disclosure, the second roller 1222 of the present disclosure can be Fig.18 The universal wheel 15 shown is fixed to the floor brush assembly 12 via a snap-fit ​​structure 155 and a shaft sleeve 154, and other structures are not described in detail.

[0128] In another embodiment of the present disclosure, the second roller 1222 is an unassisted roller. The unassisted roller is different from the universal wheel 15 in the above embodiment. The roller brush can only provide a fixed rotation direction for the floor brush housing. Compared with the assisted roller that requires a motor to drive, the friction force of the unassisted roller when the body 11 is twisted and dragged is relatively small, and the whole is also lighter. Compared with the universal wheel in the above embodiment, it can provide a certain restraining force for the overall swing of the cleaning equipment to prevent the cleaning equipment from being too flexible.

[0129] like Fig. 22As shown, in one embodiment of the present disclosure, the body 11 is rotatably disposed on the floor brush assembly 12 via a rotating shaft, and an elastic member 129 is disposed on the rotating shaft, and the elastic member 129 is configured to support the body 11 upward by its own elastic force, so that the hand-held gravity of the body 11 can be effectively reduced, thereby making it easier for the user to use the cleaning device 10 of the present disclosure. The elastic member 129 can be a torsion spring or other forms of elastic members, and the present disclosure is not limited here.

[0130] It is understandable that the machine body 11 of the present disclosure can also rotate around its own axis, that is, around the sewage suction pipe 128, to facilitate user operation. Fig.21 As shown, in one embodiment of the present disclosure, a limiting notch 126 is provided at the rear of the floor brush assembly 12 of the present disclosure, and a limiting protrusion 115 cooperating with the limiting notch 126 is provided at the bottom of the body 11. When the body 11 moves toward the working surface and the limiting protrusion 115 extends into the limiting notch 126, there is a gap between the limiting protrusion 115 and the side wall of the limiting notch 126, and the gap can be used to limit the torsion angle of the body 11. That is, when the body 11 is twisted in transition, the side wall of the limiting protrusion 115 will interfere with the side wall of the limiting notch 126, thereby preventing the body 11 from continuing to twist.

[0131] In this way, when the angle between the body 11 and the working surface is less than the preset angle, the limiting protrusion 115 can enter the limiting notch 126 to limit the rotation angle of the body 11, thereby preventing the body 11 from excessively rotating to one side, causing the sewage in the sewage bucket 14 to enter the air outlet 1431. In particular, when lying flat, it is necessary to limit the torsion angle of the body 11 to avoid the problem of the body 11 tipping over due to excessive torsion.

[0132] like Fig.21 As shown, in one embodiment of the present disclosure, the side walls on opposite sides of the limiting notch 126 may be vertically downward, so that after the limiting protrusion 115 enters the limiting notch 126, the rotatable angle of the body 11 will remain unchanged. In another embodiment of the present disclosure, the limiting notch 126 may be in the shape of an oblique groove, so that after the limiting protrusion 115 enters the limiting notch 126, the rotatable angle of the body 11 will change with the depth of the limiting protrusion 115 entering the limiting notch 126, that is, the angle between the body 11 and the working surface. Of course, the side walls of the limiting protrusion 115 may also be made into a straight line or an oblique line, which can also achieve the above-mentioned effect.

[0133] It can be understood that in one embodiment of the present disclosure, the limiting notch 126 is constructed so that when the angle between the body 11 and the working surface is greater than 15°, the body 11 can rotate 40° to the left and right relative to the working surface, and when the angle between the body 11 and the working surface is less than 15°, the body 11 can rotate 10° to the left and right relative to the working surface. The rollers on the floor brush assembly 12 can be located on the same plane as the supporting structure on the body 11, which can not only meet the user's requirement for twisting the body 11, but also improve the movement stability of the body 11 in a lying state, and prevent the body 11 from excessively rotating to one side, and prevent the sewage in the sewage bucket 14 from entering the air outlet 1431, and prevent the sewage bucket 14 from being full of water due to excessive rotation but the water full detection probe 1437 cannot detect it.

[0134] Since the cleaning liquid tank 124 of the present disclosure is arranged on the floor brush assembly 12, the downward pressure of the floor brush assembly 12 can be effectively increased, thereby improving the cleaning effect of the roller brush 123 on the working surface, and reducing the weight of the body 11, so that the user needs less force to hold the body 11, and improves the convenience of the user pulling the body 11. In addition, the cleaning liquid tank 124 of the present disclosure can act as a roller brush cover to prevent the splashing of sewage generated when the roller brush 123 rotates, saving the number of parts and material costs, and can integrate the pick-up and placement actions of the two structures into one, thereby reducing the frequency of users disassembling and assembling certain parts of the cleaning device 10.

[0135] like Fig.23 and Fig.24 As shown, the cleaning liquid tank 124 includes a box body 1241 and a cover body 1242. The cover body 1242 can be hinged at the water filling port of the box body 1241, so that the cover body 1242 is in the open state, which is convenient for the user to add water; when the water is added, the cover body 1242 can be rotated to close the water filling port to prevent water from overflowing from the box body 1241 during the use of the cleaning device 10.

[0136] like Fig.23 and Fig.24 As shown, in one embodiment of the present disclosure, a vent 12411 is provided on the cover 1242 of the present disclosure, which connects the inner cavity of the box 1241 with the outside, and a baffle 1244 is fixedly provided below the vent 12411. Since the vent 12411 is provided on the cover 1242 of the present disclosure, during the use of the cleaning device 10, the cleaning liquid in the cleaning liquid tank 124 is continuously reduced, and the external gas can enter the cleaning liquid tank 124 from the vent 12411, thereby ensuring the pressure balance between the inside and outside of the cleaning liquid tank 124, so that the cleaning liquid in the cleaning liquid tank 124 can be sprayed onto the working surface normally. Moreover, during the use of the cleaning device 10, the baffle 1244 can prevent part of the cleaning liquid from splashing to the outside through the vent 12411 due to repeated shaking of the floor brush assembly 12.

[0137] Further, such as Fig.24 As shown, a float 1243 is provided between the vent 12411 and the baffle 1244, and the float 1243 is configured to float between the vent 12411 and the baffle 1244, and float upward to close the vent 12411 when the cleaning liquid moves to the vent 12411 area. In this way, during the use of the cleaning device 10 of the present disclosure, when some water enters above the baffle 1244, the float 1243 can float upward until the float 1243 closes the vent 12411, and after the water flows back into the box body 1241, the float 1243 descends to ventilate the vent 12411 again. Therefore, the float 1243 dynamically floats up and down in the vent 12411 area, which can not only dynamically balance the air pressure inside and outside the cleaning liquid tank 124, but also effectively prevent the cleaning liquid in the cleaning liquid tank 124 from splashing to the outside. In one embodiment of the present disclosure, the float 1243 may be spherical and made of plastic or rubber, so that the float 1243 can effectively close the vent 12411 and reduce the gap between the float 1243 and the vent 12411 after they abut against each other, thereby effectively preventing the cleaning liquid in the cleaning liquid tank 124 from splashing to the outside. When the liquid level drops, the float 1243 will move downward to a position away from the vent 12411, so that the cleaning liquid tank 124 can still communicate with the outside through the vent 12411.

[0138] In one embodiment of the present disclosure, Fig.25 , Fig.26 and Fig. 27 As shown, an elastic hook 12451 is provided on the rear side of the box body 1241 of the cleaning liquid tank 124, and an unlocking button 12452 is provided on the top of the box body 1241. The elastic hook 12451 is configured to be engaged in the slot 1211 on the floor brush housing 121, and retract from the outside of the box body 1241 when the unlocking button 12452 is pressed; in this way, when installing the cleaning liquid tank 124 of the present disclosure, the elastic hook 12451 can be engaged in the slot 1211 on the floor brush housing 121, so that the cleaning liquid tank 124 is engaged in the floor brush housing 121. When the user needs to remove the cleaning liquid tank 124 from the floor brush housing 121, by pressing the unlocking button 12452, the elastic hook 12451 can be retracted from the outside of the box body 1241, and then the cleaning liquid tank 124 can be removed from the floor brush housing 121.

[0139] Further, such as Fig.26 and Fig. 27 As shown, in one embodiment of the present disclosure, a guide flange 1212 is provided on the front side of the floor brush housing 121, a brush groove 1246 for cooperating with the roller brush 123 is provided at the bottom of the front side of the cleaning liquid tank 124, and locking portions 1247 corresponding to the position of the guide flange 1212 are provided at the opposite ends of the rear side of the brush groove 1246.

[0140] In this way, in one embodiment of the present disclosure, when the cleaning liquid tank 124 can be placed from top to bottom above the floor brush housing 121 and the roller brush 123, the locking portion 1247 will contact the guide flange 1212 and move along the guide slope on the guide flange 1212 until the locking portion 1247 and the guide flange 1212 are engaged together. When engaged in place, the elastic hook 12451 is engaged in the slot 1211 on the floor brush housing 121, thereby engaging the cleaning liquid tank 124 in the floor brush housing 121.

[0141] Specifically, refer to Fig.25 and Fig.28 The guide flange 1212 of the floor brush housing 121 has two guide slopes, namely a first guide slope 1212a and a second guide slope 1212b. The first guide slope 1212a is configured to face upward and is configured to be inclined toward the front side of the floor brush housing 121. That is, in the direction from front to back, the first guide slope 1212a is configured to gradually tilt upward. The second guide slope 1212b is transitionally connected to the first guide slope 1212a and is configured to gradually tilt downward in the direction from front to back.

[0142] Correspondingly, two guiding slopes are provided on the engaging portion 1247, namely, a third guiding slope 1247a and a fourth guiding slope 1247b. The third guiding slope 1247a and the fourth guiding slope 1247b are configured to be matched with the first guiding slope 1212a and the second guiding slope 1212b, respectively. When the user places the cleaning liquid tank 124 on the floor brush housing 121, the third guide bevel 1247a of the engaging portion 1247 cooperates with the first guide bevel 1212a of the guide flange 1212, and under the action of the gravity of the cleaning liquid tank itself and the action of the guide bevel, the cleaning liquid tank 124 slides downward and forward until the third guide bevel 1247a is disengaged from the first guide bevel 1212a, and the fourth guide bevel 1247b of the engaging portion 1247 is in contact with the second guide bevel 1212b of the guide flange 1212. Under the action of external force, the cleaning liquid tank 124 continues to move downward and backward until the fourth guide bevel 1247b is completely cooperated with the second guide bevel 1212b, so that the cleaning liquid tank is engaged on the floor brush housing 121 on the front side through the guide flange 1212 and the engaging portion 1247, forming a limit for the cleaning liquid tank in the vertical direction.

[0143] When assembling the cleaning liquid tank 124 disclosed in the present invention, the user does not need to align the cleaning liquid tank 124 and the floor brush housing 121. The user only needs to place the cleaning liquid tank 124 on the floor brush housing 121, and the cleaning liquid tank 124 can be moved and the position of the cleaning liquid tank 124 can be adaptively adjusted under the guidance of the first guide bevel 1212a and the third guide bevel 1247a.

[0144] In another embodiment of the present disclosure, the installation can be performed in a rotating manner. Fig. 27 As shown, the brush groove 1246 of the cleaning liquid tank 124 can be placed on the roller brush 123 and matched together, and then the rear side of the cleaning liquid tank 124 moves downward along an arc until the engaging portion 1247 is matched with the guide flange 1212. The matching process of the engaging portion 1247 and the guide flange 1212 is as described in the above embodiment, and the disclosure will not repeat it here. When the user needs to remove the cleaning liquid tank 124 from the floor brush housing 121, by pressing the unlocking button 12452, the elastic hook 12451 can be retracted from the outside of the box body 1241, and then the cleaning liquid tank 124 is pulled up until the cleaning liquid tank 124 is completely removed from the floor brush housing 121.

[0145] Further, such as Fig.26 and Fig. 27 As shown, in one embodiment of the present disclosure, a protrusion 1248 is provided below the cleaning liquid tank 124 of the present disclosure, which can effectively increase the capacity of the cleaning liquid tank 124. A receiving groove 1213 is provided at the position between the corresponding protrusions 1248 of the floor brush housing 121, and an oblique guide portion 12481 is provided at the front end of the bottom of the protrusion 1248. The upper end of the front side wall of the receiving groove 1213 is a first contact wall 12131, and the bottom end of the front side wall is provided with a second contact wall 12132. The first contact wall 12131 and the second contact wall 12132 are connected by an oblique guide surface 12133, and the distance between the first contact wall 12131 and the rear side wall of the receiving groove 1213 is greater than the length of the protrusion 1248 in the front-to-back direction of the floor brush assembly 12, and the distance between the second contact wall 12132 and the front side wall of the receiving groove 1213 is approximately equal to the length of the protrusion 1248 in the front-to-back direction of the floor brush assembly 12.

[0146] When the user places the cleaning liquid tank 124 on the floor brush housing 121 from top to bottom, the protrusion 1248 will extend into the receiving groove 1213, and under the cooperation of the third guide slope 1247a of the above-mentioned engaging portion 1247 and the first guide slope 1212a of the guide flange 1212, the cleaning liquid tank 124 moves downward and forward until the inclined guide portion 12481 contacts the inclined guide surface 12133. The inclined guide surface 12133 gradually tilts downward from the front to the back, so that the cleaning liquid tank 124 gradually moves downward and backward under the action of its own gravity and under the guidance of the inclined guide portion 12481 and the inclined guide surface 12133, until the front side wall of the protrusion 1248 is in contact with the second contact wall 12132, that is, the protrusion 1248 is located in the space surrounded by the second contact wall 12132 and the rear side wall of the receiving groove. As the cleaning liquid tank 124 gradually moves downward and toward the rear, the fourth guide slope 1247b gradually fits with the second guide slope 1212b. At the same time, the elastic hook 12451 is engaged with the slot 1211 on the floor brush housing 121, thereby engaging the cleaning liquid tank 124 in the floor brush housing 121. In this way, the cleaning liquid tank 124 can be clamped in the receiving slot 1213 through the second contact wall 12132 and the rear side wall of the receiving slot 1213.

[0147] The cleaning liquid tank 124 disclosed in the present invention has its front side engaged with the guide flange 1212 of the floor brush housing 121 through the engaging portion 1247; wherein the rear side is engaged with the receiving groove 1213 on the floor brush housing 121 through the protruding portion 1248, thereby realizing the stable installation of the cleaning liquid tank 124 and the floor brush housing 121, and preventing the cleaning liquid tank 124 from shaking back and forth when the cleaning device is working. In addition, the above-mentioned adaptive installation method is adopted, so that the user does not need to accurately align the cleaning liquid tank 124 when installing it, and the cleaning liquid tank 124 can adapt to the correct installation position under the action of various guide inclined surfaces.

[0148] like Fig.24 As shown, in one embodiment of the present disclosure, a disinfection device 125 is provided in the cleaning liquid tank 124 of the present disclosure, and the disinfection device 125 can generate a substance with a disinfection function during operation, thereby effectively improving the cleaning effect of the cleaning liquid. Fig.24 As shown, the disinfection device 125 of the present disclosure is provided with a power supply contact 1251 extending outward from the box body 1241 , and the power supply contact 1251 can fit with the power supply part on the floor brush housing 121 and achieve elastic contact to supply power to the disinfection device 125 .

[0149] Among them, in one embodiment of the present disclosure, the upper box body 1241 of the cleaning liquid tank 124 of the present disclosure is partially transparent, so that during the working process of the disinfection device 125, the user can intuitively observe the working process of the disinfection device 125. In order to further facilitate the user to observe the working process of the disinfection device 125, in one embodiment of the present disclosure, a lighting assembly is provided in the disinfection device 125 of the present disclosure, and the lighting assembly is configured to emit light when the disinfection device 125 is working. In this way, the light provided by the lighting assembly allows the user to clearly see the working status of each position of the disinfection device 125, for example, the lighting assembly illuminates the bubbles floating upward generated from the disinfection device 125, thereby improving the user experience.

[0150] like Fig.24 As shown, in one embodiment of the present disclosure, the disinfection device 125 of the present disclosure can be arranged in the protrusion 1248, and its power supply contact 1251 extends outward from the rear side of the protrusion 1248. In this way, after the cleaning liquid tank 124 of the present disclosure is installed on the floor brush housing 121, the power supply contact 1251 is connected to the corresponding electrode of the floor brush housing 121, and the elastic power supply contact 1251 has an elastic force to push the cleaning liquid tank 124 forward. When the user presses the unlocking button 12452 of the cleaning liquid tank 124, the cleaning liquid tank 124 has a tendency to move forward.

[0151] Continue to refer Fig.24 The bottom of the cleaning liquid tank 124 is provided with a water outlet valve 1249, which can also be provided at the bottom of the protrusion 1248. The floor brush housing 121 is provided with a docking valve that docks with the water outlet valve 1249 of the cleaning liquid tank 124. In order to achieve the ability to switch between the sealed position and the open position, the water outlet valve 1249 is provided with a corresponding elastic device. This water outlet valve 1249 belongs to the common knowledge of those skilled in the art, and will not be described in detail in this disclosure. That is to say, after the water outlet valve 1249 docks with the docking valve, it has an elastic force that pushes the cleaning liquid tank 124 upward.

[0152] In this way, when the user presses the unlocking button 12452 of the cleaning liquid tank 124, the cleaning liquid tank 124 can automatically pop out from the floor brush housing 121 under the action of the upward elasticity provided by the water outlet valve 1249 and the forward elasticity provided by the power supply contact 1251, so that the user can remove the cleaning liquid tank 124 from the floor brush housing 121.

[0153] like Fig.30 , Fig.31As shown, in one embodiment of the present disclosure, a charging contact 1271 is provided at the bottom of the floor brush assembly 12 of the present disclosure, and a charging movable part 211 is provided on the tray 20. When the cleaning device 10 of the present disclosure is placed on the tray 20, the charging movable part 211 can be connected to the charging contact 1271 to charge the battery assembly of the cleaning device 10 of the present disclosure. In this way, the bottom space of the floor brush assembly 12 can be effectively utilized, thereby improving the space utilization rate of the floor brush assembly 12 and reducing the required space of the body 11.

[0154] Specifically, Fig.30 As shown, in one embodiment of the present disclosure, two charging docking cavities 127 are provided at the bottom of the floor brush assembly 12 of the present disclosure, and charging contacts 1271 are provided in the two charging docking cavities 127. A charging part 21 corresponding to the position of the charging docking cavity 127 is provided on the tray 20, and a charging movable part 211 is provided on the charging part 21. When the cleaning device 10 is placed on the tray 20, the charging part 21 can be inserted into the charging docking cavity 127, and the charging movable part 211 is connected to the charging contacts 1271 in the charging docking cavity 127, thereby charging the cleaning device 10 of the present disclosure.

[0155] Since the two charging contacts 1271 on the floor brush assembly 12 are separately placed in two independent charging docking cavities 127 with a certain distance between them, even if there is water residue at the bottom of the floor brush assembly 12, a short circuit between the two charging contacts 1271 can be effectively avoided, and electrolytic corrosion between the two charging contacts 1271 can be avoided.

[0156] Similar, such as Fig.30 As shown, the two charging movable parts 211 are respectively arranged on the two charging parts 21 with their backs facing each other, and there is a certain distance between them. Even if water enters the tray 20, it can effectively prevent the two charging movable parts 211 from short-circuiting and avoid electrolytic corrosion between the two charging movable parts 211.

[0157] like Fig.31 As shown, in one embodiment of the present disclosure, the charging movable part 211 of the present disclosure is arranged on the charging part 21 through the compression spring 212, so that the compression spring 212 can press the charging movable part 211 on the charging contact 1271 of the floor brush assembly 12, thereby preventing poor contact between the charging movable part 211 and the charging contact 1271. When the floor brush assembly 12 is placed on the tray 20 or removed from the tray 20, the charging movable part 211 can remove the debris attached to the charging contact 1271, thereby further avoiding poor contact between the charging movable part 211 and the charging contact 1271.

[0158] like Fig.31As shown, in one embodiment of the present disclosure, one end of the compression spring 212 is fixed to the charging movable part 211, and the other end is rotatably connected to the tray 20 via the rotating shaft 213, so that the charging movable part 211 can swing upward or downward. When the cleaning device 10 of the present disclosure shakes or vibrates on the tray 20, the compression spring 212 and the charging movable part 211 can rotate a certain angle via the rotating shaft 213, thereby ensuring that the charging movable part 211 and the charging contact 1271 on the floor brush assembly 12 are always connected together, avoiding electric sparks or poor charging problems due to vibration between the two.

[0159] The first contact position and the charging holding position of the charging movable part 211 and the charging contact 1271 of the present disclosure are not the same position. This is because when the user places the cleaning device on the tray 20, the charging contact 1271 on the cleaning device will first contact the charging movable part 211. In the process of continuing to place it downward, the charging movable part 211 is squeezed to move into the charging part 21, and the contact position of the charging contact 1271 and the charging movable part 211 will change accordingly with the change of the posture of the cleaning device. For example, when the cleaning device is placed in a tilted posture on both sides, the force between the charging contact 1271 and the charging movable part 211 is uneven. At this time, the charging movable part 211 can rotate a corresponding angle under the action of the rotating shaft 213 to adaptively adjust its contact position with the charging contact 1271 and ensure that it can fully contact with the charging contact 1271.

[0160] like Fig.32 As shown, in one embodiment of the present disclosure, the rear side of the charging docking cavity 127 is constructed so that the bottom end is inclined toward the front end of the floor brush assembly 12, and the rear side of the charging part 21 is constructed to gradually tilt forward from top to bottom. This allows an interference point to be provided between the charging part 21 and the charging docking cavity 127 at the position of the rear side, and the interference point can be located at the bottom position of the charging part 21. When the cleaning device 10 of the present disclosure is placed on the tray 20 for charging, the rear side of the charging docking cavity 127 can ensure a tight fit between the charging docking cavity 127 and the charging part 21, effectively solving the problem of the cleaning device 10 being unable to charge due to the excessive inclination angle or the tray 20 being too large. When the cleaning device 10 is placed on the tray 20 for charging, even if the body 11 is pushed toward the front side, the cleaning device 10 will not flip toward the front side around the roller brush 123, causing the charging docking cavity 127 and the charging part 21 to separate from each other. Even if the cavity wall of the charging docking cavity 127 of the cleaning device 10 is slightly worn after being used for a period of time, when the cleaning device 10 is placed on the tray 20 and the body 11 is tilted forward at one angle, the cleaning device 10 can be charged normally.

[0161] In one embodiment of the present disclosure, a heating component is also provided on the tray 20 of the present disclosure, so that when the cleaning device 10 of the present disclosure is placed on the tray 20 for charging, the heating component on the tray 20 can dry and clean the roller brush 123 of the floor brush assembly 12 through the air duct.

[0162] like Figures 1 to 15 As shown, in one embodiment of the present disclosure, the side of the cleaning device 10 facing the user is recorded as the rear side, and the side away from the user is recorded as the front side. The cleaning device 10 of the present disclosure includes:

[0163] Floor brush assembly 12;

[0164] The machine body 11 is configured to be able to rotate relative to the brush assembly 12 to make its extension direction parallel to the working surface so as to be in a flat state, and a sewage bucket 14 is provided at the front side of the machine body 11;

[0165] The sewage bucket 14 includes a bucket cover and a barrel body 142, and a sewage inlet channel 1411 is arranged in the barrel body 142. The bucket cover of the sewage bucket 14 is provided with a main partition 1433, an air outlet 1431 and a guide channel 1432. The main partition 1433 is in contact with the barrel body 142 on two opposite sides and extends along the extension direction of the body 11, dividing the upper part of the inner cavity 144 into a first area located on the front side and a third area located on the rear side. The sewage inlet channel 1411 is arranged in the third area, and the air outlet 1431 is arranged in the first area. The outlet of the guide channel 1432 is constructed to be higher than the main partition 1433 when the body 11 is in a lying state, and the inlet of the guide channel 1432 is connected with the sewage inlet channel 1411.

[0166] Since the main partition 1433 can separate the upper area of ​​the inner cavity 144 into a first area located at the front side and a third area located at the rear side, and the sewage inlet channel 1411 is arranged in the third area, the air outlet 1431 is arranged in the first area, and the outlet of the guide channel 1432 is constructed to be higher than the main partition 1433 when the machine body 11 is in a flat state, and the inlet of the guide channel 1432 is connected with the sewage inlet channel 1411, it can ensure that the sewage is in the third area when the machine body 11 is in a flat state, so as to be blocked by the main partition 1433, and it can also ensure that the sewage entering from the rear side can flow to the front side through the guide channel 1432, so as to avoid the accumulation and collision of sewage. In addition, when the machine body 11 of the present disclosure is working in a flat state, it is ensured that the dirt can flow out from a position higher than the main partition 1433. When the machine body of the present disclosure works at an inclined angle, since the outlet of the guide channel 1432 is located in the front area of ​​the top of the upper cover 143, sewage can be prevented from flowing back into the outlet.

[0167] like Figures 8 to 14As shown, in one embodiment of the present disclosure, the guide channel 1432 penetrates the main partition 1433 to form an outlet, and the inlet and outlet of the guide channel 1432 are separated by the main partition 1433 at the front and rear sides of the inner cavity 144, thereby effectively ensuring that the sewage entering from the rear side can pass through the guide channel 1432 and penetrate the main partition 1433 to flow to the front side, thereby avoiding the accumulation and collision of sewage.

[0168] Further, such as Fig.10 As shown, in one embodiment of the present disclosure, the guide channel 1432 passes through the interface formed by the main partition 1433 and is arranged near the barrel cover. Since the guide channel 1432 passes through the interface and is arranged near the barrel cover, the guide channel 1432 can be easily arranged to fit the bottom of the barrel cover.

[0169] like Fig.10 As shown, in one embodiment of the present disclosure, the outlet of the diversion channel 1432 is configured to be disposed toward the barrel wall of the barrel body 142. Since the outlet of the diversion channel 1432 is disposed toward the barrel wall of the barrel body 142, the sewage can flow out of the outlet of the diversion channel 1432 and impact the through wall of the barrel body 142, thereby slowing down the flow speed of the sewage.

[0170] like Fig.10 and Fig.11 As shown, in one embodiment of the present disclosure, the sewage bucket 14 further includes a solid-liquid separation frame 1434, which is located below the main partition 1433. The solid-liquid separation frame 1434 is configured to extend perpendicularly to the extension direction of the body 11 and has a gap for the sewage inlet channel 1411 to pass through; the solid-liquid separation frame 1434 and the main partition 1433 are configured to be spaced apart to form a water discharge gap 1436 in the extension direction of the body 11. When the body 11 is in an inclined state, after the dirt flows out from the outlet of the guide channel 1432, it flows downward along the main partition 1433 and continues to flow downward through the water discharge gap 1436, thereby preventing the dirt from accumulating between the main partition 1433 and the solid-liquid separation frame 1434.

[0171] like Fig.10 As shown, in one embodiment of the present disclosure, the sewage barrel 14 also includes a partition plate 1435, which is fixedly arranged on the main partition plate 1433 and is constructed to extend from the end face of the main partition plate 1433 toward the barrel body 142, and fit with the front side wall of the barrel body 142 to laterally divide the first area into two areas, and the outlet of the air outlet 1431 and the outlet of the guide channel 1432 are respectively located in the two areas separated by the partition plate 1435, thereby ensuring that the air outlet 1431 and the outlet of the guide channel 1432 are separated by the partition plate 1435, thereby preventing sewage from flowing directly from the outlet of the guide channel 1432 to the air outlet 1431.

[0172] like Fig.10 As shown, in one embodiment of the present disclosure, the partition plate 1435 is constructed to divide the first area into a first sub-area A1 and a second sub-area A2 arranged transversely, the outlet of the guide channel 1432 is located in the first sub-area A1, and the air outlet 1431 is located in the second sub-area A2; the sewage bucket 14 also includes a solid-liquid separation frame 1434 located below the main partition plate 1433, and a third sub-area A3 is formed between the solid-liquid separation frame 1434 and the partition plate 1435, which is transversely connected to the first sub-area A1 and the second sub-area A2. In this way, the airflow can flow from the first sub-area A1 to the third sub-area A3, and then flow to the second sub-area A2, and flow out of the sewage bucket 14 from the air outlet 1431, and the sewage will flow from the first sub-area A1 to the third sub-area A3, and then remain in the sewage bucket 14.

[0173] like Fig.10 As shown, in one embodiment of the present disclosure, the partition plate 1435 is constructed to be set away from the center line of the main partition plate 1433 so that the width of the first sub-area A1 is smaller than the width of the second sub-area A2, thereby ensuring that the airflow can flow from the first sub-area A1 to the third sub-area A3, and when it flows to the second sub-area A2, the gas flow rate is reduced, and sewage is prevented from following the gas flow to the outlet 1431 in the second sub-area A2 as much as possible, thereby preventing sewage from entering the fan assembly 16 and preventing the fan assembly 16 from being damaged due to water ingress.

[0174] like Fig.10 and Fig.13 As shown, in one embodiment of the present disclosure, the solid-liquid separation frame 1434 includes a front separation area 14341 provided with a separation hole 14344 and a middle partition area 14342 not provided with the separation hole 14344, the middle partition area 14342 is located in the area directly below the main partition 1433, and the front separation area 14341 is located on the front side of the main partition 1433, so that dirt can flow downward through the separation hole 14344, and when lying flat, when the body 11 is pushed and pulled, the sewage in the C area and the D area will have a large fluctuation, and the fluctuating sewage cannot pass through the middle partition area 14342 to flow to the A area and the A area, thereby preventing the sewage from being brought into the air outlet 1431 when it fluctuates.

[0175] like Fig.15 and Fig.33As shown, in one embodiment of the present disclosure, the sewage bucket 14 also includes a water full detection probe 1437, and the end of the water full detection probe 1437 is located above the solid-liquid separation frame 1434. During the use of the cleaning device 10 of the present disclosure, when the water full detection probe 1437 is soaked by sewage, the water full detection probe 1437 can trigger a water full signal, and the cleaning device 10 of the present disclosure can stop working in time according to the water full signal to avoid excessive sewage in the sewage bucket 14, overflow or sewage being sucked into the fan assembly 16. Since the end of the water full detection probe 1437 is located above the solid-liquid separation frame 1434, it can be ensured that the effective capacity of the sewage bucket 14 can meet the requirements.

[0176] Further, such as Fig.15 and Fig.33 As shown, in one embodiment of the present disclosure, the middle partition area 14342 of the solid-liquid separation frame 1434 has sinking areas 14345 on both sides that are lower than the middle partition area 14342, and in the extension direction of the body 11, the end of the water full detection probe 1437 is lower than the middle partition area 14342 but higher than the sinking area 14345.

[0177] As a result, the end of the water full detection probe 1437 can be lower than the end surface of the solid-liquid separation frame 1434, that is, lower than the end surfaces of the front separation area 14341, the middle partition area 14342 and the rear separation area 14343, so that the detection end of the water full detection probe 1437 can be triggered before the sewage reaches the front separation area 14341, the middle partition area 14342 and the rear separation area 14343, ensuring the early triggering of the dirty and sewage fullness.

[0178] In one embodiment of the present disclosure, region A is close to the air outlet and has a high gas flow rate, while region C is far away from the air outlet 1431 and has a low gas flow rate. According to the Bernoulli principle, a pressure difference is formed between region A and region C. Therefore, there is a suction force from region C to region A in the probe end region. When the body 11 is in an inclined state and the sewage water level line reaches region C and is located below the probe end without contact and conduction, there is a gap between the bottom surface of the probe groove 14381 and the sinking area 14345. The suction force from region C to region A brings the sewage into the probe in the probe groove 14381 through the aforementioned gap and achieves conduction. In this way, when the sewage reaches the sinking area 14345 but does not immerse the solid-liquid separation frame 1434, the water full detection probe 1437 can be triggered in advance to ensure the accuracy of the water full detection. When the body 11 is placed in a vertical state or horizontally, the sewage water level line gradually rises into the probe groove 14381 to contact and conduct with the probe. Through the above settings, this embodiment can realize water fullness detection in three states through a pair of probes, and can ensure that the volumes of the three areas B, C, and D account for a larger proportion of the overall volume of the sewage bucket 14, while balancing the sewage volume in the three states, thereby ensuring the utilization rate of the sewage storage space in the sewage bucket 14.

[0179] like Fig.15 As shown, in one embodiment of the present disclosure, the water full detection probe 1437 has a first section extending vertically downward and a second section extending downward and tilted forward from the first section. The connection between the first section and the second section is a water full detection point when the machine body 11 is in a flat state, and the end of the second section is a water full detection point when the machine body 11 is in a vertical state or a tilted state. In this way, the water full detection probe 1437 of the present disclosure can effectively ensure the water full detection accuracy when the machine body 11 is in various postures, without the need to set multiple water full detection probes 1437 according to different situations. While the structure is simple, it can also ensure the utilization rate of the sewage volume in the sewage bucket 14.

[0180] like Figure 6 As shown, in one embodiment of the present disclosure, a handle structure 1452 is provided on the front side of the bucket cover, and a handle is provided on the bucket body 142 adjacent to the handle structure 1452. The handle is configured to be arranged against the body of the sewage bucket 14 in an unstressed state, and deflected outward relative to the sewage bucket 14 in a stressed state, thereby forming a handle space. In an unstressed state, the handle can be placed against the body of the sewage bucket 14, thereby effectively reducing the overall height of the body 11 in a flat state, and saving the occupied space to increase the volume of the inner cavity 144 of the sewage bucket 14. In a stressed state, the handle can be deflected outward relative to the sewage bucket 14, thereby forming a handle space for the user's fingers to extend into, so that the user can take the sewage bucket 14 out of the mounting groove 111.

[0181] Further, such as Figure 6As shown, in one embodiment of the present disclosure, a plane is provided on the front side of the barrel body 142 to form an inward depression, and a handle is provided on the plane and is configured to be in contact with the plane in an unstressed state, thereby further saving the space occupied by the handle to increase the volume of the inner cavity 144 of the sewage bucket 14.

[0182] like Figure 1 and Fig.24 As shown, in one embodiment of the present disclosure, a cleaning liquid tank 124 is provided on the floor brush assembly 12, and a brush groove 1246 for cooperating with the roller brush 123 is provided at the bottom of the front side of the cleaning liquid tank 124, and the cleaning liquid tank 124 includes a box body 1241, and the box body 1241 is configured to extend forward to the top of the brush groove 1246 and forward beyond the axial position of the roller brush 123. In this way, the effective volume of the cleaning liquid tank 124 can be effectively increased, and the cleaning liquid tank 124 can be used as a roller brush cover.

[0183] In one embodiment of the present disclosure, a protrusion 1248 is provided under the cleaning liquid tank 124, and the floor brush assembly includes a floor brush shell 121, the floor brush shell 121 is provided with a receiving groove 1213 corresponding to the protrusion 1248, and the cleaning liquid tank 124 is provided with a disinfection device 125 in the protrusion 1248.

[0184] That is, the cleaning liquid tank 124 of the present invention can be engaged with the receiving groove 1213 on the floor brush housing 121 through the protrusion 1248, thereby realizing the stable installation of the cleaning liquid tank 124 and the floor brush housing 121, and avoiding the back and forth shaking of the cleaning liquid tank 124 when the cleaning device is working. In addition, the above-mentioned adaptive installation method is adopted, so that the user does not need to accurately align when installing the cleaning liquid tank 124, and the cleaning liquid tank 124 can adapt to the correct installation position under the action of various guide slopes. In addition, since the cleaning liquid tank 124 is provided with a disinfection device 125 in the protrusion 1248, the power supply contact 1251 of the disinfection device 125 can extend outward from the rear side of the protrusion 1248. In this way, after the cleaning liquid tank 124 of the present invention is installed on the floor brush housing 121, the power supply contact 1251 is connected to the corresponding electrode of the floor brush housing 121, and the elastic power supply contact 1251 has an elastic force to push the cleaning liquid tank 124 forward. When the user presses the unlocking button 12452 of the cleaning liquid tank 124, the cleaning liquid tank 124 tends to move forward.

[0185] The present disclosure also provides a sewage bucket 14, including a bucket cover and a barrel body 142, wherein a sewage inlet channel 1411 is arranged in the barrel body 142, and a main partition 1433, an air outlet 1431 and a guide channel 1432 are arranged on the bucket cover of the sewage bucket 14, and the two opposite sides of the main partition 1433 are in contact with the barrel body 142 and extend along the extension direction of the sewage bucket 14, so as to divide the upper part of the inner cavity 144 into a first area located at the front side and a third area located at the rear side, the sewage inlet channel 1411 is arranged in the third area, and the air outlet 1431 is arranged in the first area; the inlet of the guide channel 1432 is connected with the sewage inlet channel 1411, and the guide channel 1432 extends from its inlet through the main partition to form an outlet located in the first area.

[0186] Since the main partition 1433 can separate the upper area of ​​the inner cavity 144 into a first area located at the front side and a third area located at the rear side, and the sewage inlet channel 1411 is arranged in the third area, the air outlet 1431 is arranged in the first area, the inlet of the guide channel 1432 is connected with the sewage inlet channel 1411, and the guide channel 1432 extends from its inlet through the main partition to form an outlet located in the first area, it can ensure that the sewage is in the third area when the sewage bucket 14 is in a flat state, so that it is blocked by the main partition 1433, and it can also ensure that the sewage entering from the rear side can flow to the front side through the guide channel 1432, so as to avoid the accumulation and collision of sewage. In addition, when the sewage bucket 14 of the present disclosure works in a flat state, it is ensured that the dirt can flow out from a position higher than the main partition 1433. When the body of the present disclosure works at an inclined angle, since the outlet of the guide channel 1432 is located in the front area of ​​the top of the upper cover 143, it can prevent the sewage from flowing back into the outlet.

[0187] In one embodiment of the present disclosure, the sewage bucket 14 also includes a partition plate 1435 and a solid-liquid separation frame 1434. The partition plate 1435 is fixedly arranged on the main partition plate 1433, and is constructed to extend from the end face of the main partition plate 1433 toward the barrel body 142, and is fitted with the front side wall of the barrel body 142 to divide the first area into a first sub-area A1 and a second sub-area A2 arranged laterally. The outlet of the guide channel 1432 is located in the first sub-area, and the air outlet 1431 is located in the second sub-area; the solid-liquid separation frame 1434 is located below the main partition plate 1433, and the solid-liquid separation frame 1434 is constructed to extend perpendicular to the extension direction of the sewage bucket 14, and a third sub-area A3 is formed between the solid-liquid separation frame 1434 and the partition plate 1435, which is laterally connected to the first sub-area A1 and the second sub-area A2.

[0188] In this way, the air flow can flow from the first sub-area A1 to the third sub-area A3, and then to the second sub-area A2, and flow out of the sewage bucket 14 from the air outlet 1431, while the sewage will flow from the first sub-area A1 to the third sub-area A3, and then remain in the sewage bucket 14.

[0189] Application Scenario

[0190] The present disclosure provides a cleaning device 10, comprising a body 11 and a floor brush assembly 12. The body 11 is used as a carrier and is configured to install various functional elements required for the cleaning device 10. The floor brush assembly 12 is disposed at the bottom of the body 11 and is configured to clean a working surface.

[0191] The body 11 is provided with a sewage bucket 14 and a fan assembly 16. The sewage bucket 14 is used to contain dirt sucked from the working surface by the cleaning device 10. The fan assembly 16 is used to form a negative pressure in the sewage bucket 14 to suck the dirt on the working surface into the sewage bucket 14. The floor brush assembly 12 is provided with a roller brush 123 and a cleaning liquid tank 124. The roller brush 123 is configured to clean the working surface. The cleaning liquid tank 124 is configured to contain cleaning liquid and spray the cleaning liquid onto the roller brush 123 and / or the working surface.

[0192] Since the cleaning liquid tank 124 of the present disclosure is arranged on the floor brush assembly 12, the downward pressure of the floor brush assembly 12 can be effectively increased, thereby improving the cleaning effect of the roller brush 123 on the working surface, and reducing the weight of the body 11, so that the user needs less force to hold the body 11, and improves the convenience of the user pulling the body 11. In addition, the cleaning liquid tank 124 of the present disclosure can act as a roller brush cover to prevent the splashing of sewage generated when the roller brush 123 rotates, saving the number of parts and material costs, and can integrate the pick-up and put-down actions of the two structures into one, thereby reducing the frequency of pick-up and put-down when the user uses the cleaning device 10 of the present disclosure.

[0193] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
