[0056] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] The cleaning device disclosed in the present invention at least includes a floor brush assembly, which includes a floor brush body, a roller brush and a cleaning liquid tank, wherein the roller brush is rotatably connected to the front side of the floor brush body and is constructed to rotate relative to a working surface to clean the working surface; the cleaning liquid tank is detachably connected to the floor brush body, and the cleaning liquid tank includes a box body having a liquid storage chamber; wherein a side of the box body adjacent to the roller brush is constructed to extend to above the roller brush; the orthographic projections of the liquid storage chamber and the roller brush on the working surface at least partially overlap.

[0063] 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 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 removal and placement actions of the cleaning liquid tank and the brush cover into one, thereby reducing the number of times the user disassembles and assembles parts, thereby reducing the frequency of user removal and placement.

[0064] Moreover, since one side of the box body adjacent to the roller brush extends to above the roller brush, and the orthographic projections of the liquid storage chamber and the roller brush on the working surface at least partially overlap, the extension length of the liquid storage chamber can be effectively increased, thereby increasing the capacity of the liquid storage chamber. As a result, the cleaning device of the present invention can be used in a whole-house cleaning process without the need to frequently add cleaning liquid to the cleaning liquid tank, thereby effectively reducing the number of times the user needs to add cleaning liquid, thereby effectively improving the user experience.

[0065] For ease of understanding, refer to Figures 1 to 9 , the specific structure and working principle of the cleaning device disclosed in the present invention are described in detail with reference to an embodiment. It should be noted that the directional words "front and back" used in this article to describe the structure of the cleaning device are set based on the user. When the user holds the cleaning device, the side close to the user is recorded as the back side of the cleaning device, and the side away from the user is recorded as the front side of the cleaning device.

[0066] like Figure 1 and Figure 2 As shown, the present disclosure provides a cleaning device. The cleaning device is used to clean working surfaces such as floors and carpets, and can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, and other handheld cleaning devices well 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 the user uses the floor scrubber for cleaning, the user can push the floor scrubber to move on the working surface and clean the working surface.

[0067] like Figure 3 and Figure 4 As shown, the cleaning device of the present disclosure comprises at least a floor brush assembly 10, which comprises a floor brush body 1, a roller brush 3 and a cleaning liquid tank 2, wherein the floor brush body 1 is used to install the various components of the floor brush assembly 10, the roller brush 3 is rotatably connected to the front side of the floor brush body 1, and is constructed to rotate relative to the working surface to clean the working surface; the cleaning liquid tank 2 is detachably connected to the floor brush body 1, and the cleaning liquid tank 2 comprises a box body 21 having a liquid storage chamber 22; wherein a side of the box body 21 adjacent to the roller brush 3 is constructed to extend to above the roller brush 3; the positive projections of the liquid storage chamber 22 and the roller brush 3 on the working surface at least partially overlap.

[0068] The cleaning device of the present disclosure may further include a body 20 for mounting a sewage bucket, and a handheld component 30 for a user to hold. The structure may refer to existing cleaning devices and will not be described in detail herein.

[0069] Since the cleaning liquid tank 2 of the present invention is arranged on the floor brush assembly 10, the weight of the body 20 can be reduced, so that the force required for the user to hold the body 20 is smaller, and the convenience of the user pushing and pulling the body 20 is improved. In addition, the cleaning liquid tank 2 is arranged on the floor brush assembly 10, which can effectively increase the downward pressure of the floor brush assembly 10, thereby improving the cleaning effect of the roller brush 3 on the working surface. The cleaning liquid tank 2 of the present invention can act as a brush cover 23 to prevent the splashing of sewage generated when the roller brush 3 rotates, saving the number of parts and material costs, and can integrate the removal and placement actions of the cleaning liquid tank 2 and the brush cover 23 into one, thereby reducing the number of times the user disassembles and assembles parts, thereby reducing the frequency of user removal and placement.

[0070] Moreover, since one side of the box body 21 adjacent to the roller brush 3 extends to above the roller brush 3, and the positive projections of the liquid storage chamber 22 and the roller brush 3 on the working surface at least partially overlap, this can effectively increase the extension length of the liquid storage chamber 22, and then increase the capacity of the liquid storage chamber 22, so that the cleaning device of the present invention can be used in a whole-house cleaning process without frequently adding cleaning liquid to the cleaning liquid tank 2, thereby effectively reducing the number of times the user adds cleaning liquid, and effectively improving the user experience.

[0071] Further, in one embodiment of the present disclosure, Figure 3 As shown, the cleaning liquid tank 2 further includes a brush cover 23 integrally arranged at the bottom front side of the tank body 21, and the brush cover 23 is configured to be located above the roller brush 3 and has a brush groove 24 adapted to the roller brush 3. In this way, during the use of the cleaning device disclosed in the present invention, the roller brush 3 is located below the brush groove 24 and partially enters the brush groove 24, and the brush cover 23 can effectively prevent the splashing of sewage generated when the roller brush 3 rotates, and prevent the splashing sewage from contaminating the cleaned area, thereby effectively improving the user experience.

[0072] like Figure 5 and Figure 6 As shown, in one embodiment of the present disclosure, a protrusion 211 is provided below the box body 21, and a receiving groove 11 is provided at a position corresponding to the protrusion 211 of the floor brush body 1, and the protrusion 211 is configured to be snapped into the receiving groove 11, so that the cleaning liquid box 2 is installed on the floor brush body 1; wherein, part of the liquid storage cavity 22 is located in the protrusion 211, and in the projection of the working surface, the protrusion 211 is completely located inside the box body 21. Since part of the liquid storage cavity 22 is located in the protrusion 211, the protrusion 211 can not only install the box body 21 on the floor brush body 1, but also be used to store cleaning liquid, thereby effectively increasing the capacity of the liquid storage cavity 22 of the present disclosure and reducing the number of times the user adds cleaning liquid.

[0073] like Figure 6As shown, in one embodiment of the present disclosure, a water spray plate 4 is provided on the floor brush body 1, and the water spray plate 4 is configured to be connected to the water outlet valve 26 of the cleaning liquid tank 2, and is used to spray the cleaning liquid in the cleaning liquid tank 2 onto the roller brush 3. In this way, during the operation of the cleaning device of the present disclosure, the cleaning liquid in the cleaning liquid tank 2 can be continuously sprayed onto the roller brush 3, so as to effectively wet the roller brush 3, thereby facilitating the roller brush 3 to clean the working surface.

[0074] Further, such as Figure 7 As shown, a scraper bar 27 may be provided at the rear side of the brush groove 24 , and the scraper bar 27 is configured to abut against the roller brush 3 so as to press the roller brush 3 and scrape out the dirty water attached to the roller brush 3 when the cleaning device cleans the working surface.

[0075] In this way, during the operation of the cleaning equipment, when the scraper bar 27 scrapes off the sewage attached to the roller brush 3, the cleaning liquid sprayed from the cleaning box can moisten the roller brush 3 with a lower amount of sewage, and the moistened roller brush 3 can contact the working surface to clean the working surface. This can reduce the overall dirt content on the roller brush 3, improve the cleanliness of the roller brush 3, and then improve the cleanliness of the working surface after the roller brush 3 is cleaned.

[0076] Specifically, Figure 4 As shown, in one embodiment of the present disclosure, the liquid storage chamber 22 and the roller brush 3 partially overlap in the orthographic projection on the working surface, that is, Figure 3 As shown, the longitudinal axis of the front edge of the brush cover 23 is recorded as axis a, the longitudinal axis of the front edge of the liquid storage chamber 22 is recorded as axis b, and the longitudinal axis of the rear edge of the brush cover 23 is recorded as axis c; wherein axis a, axis b and axis c are configured to be arranged in sequence from front to back. In this way, the liquid storage chamber 22 of the present disclosure partially covers the roller brush 3, and the brush cover 23 can protrude in front of the box 21 and cover the roller brush 3, so as to play a certain protective role on the liquid storage chamber 22 and the roller brush 3, and avoid direct collision with the box 21 or the roller brush 3.

[0077] It can be understood that, in another embodiment of the present disclosure, the longitudinal axis of the lowest point of the scraper strip 27 can be recorded as axis c, that is, the scraper strip 27 is the rear edge of the brush cover 23, and the scraper strip extends along the radial direction of the roller brush. The positional relationship between axis a, axis b and axis c is the same as mentioned above, and the above-mentioned technical effects can be achieved, which will not be repeated here.

[0078] In another embodiment of the present disclosure, the orthographic projection of the liquid storage chamber 22 on the working surface completely covers the orthographic projection of the roller brush 3 on the working surface, so that the capacity of the liquid storage chamber 22 can be further increased and the number of times the user adds cleaning liquid can be reduced.

[0079] Further, such as Figure 3As shown, in one embodiment of the present disclosure, the distance between axis a and axis b ranges from 0 mm to 79 mm, wherein when the distance between axis a and axis b is 0, it means that axis a and axis b completely overlap, that is, the front edge of the liquid storage cavity 22 is located directly above the longitudinal axis of the front edge of the brush cover 23. Similarly, Figure 3 As shown, in one embodiment of the present disclosure, the distance between axis b and axis c ranges from 0 mm to 56 mm. It is understandable that in order to ensure that the orthographic projections of the liquid storage chamber 22 and the roller brush 3 on the working surface have overlapping parts, the distance between axis b and axis c needs to be greater than 0 mm and cannot be equal to 0 mm. Under the conditions that the distance between axis a and axis b ranges from 0 mm to 79 mm and / or the distance between axis b and axis c ranges from 0 mm to 56 mm, the size of the liquid storage chamber 22 is more appropriate, the capacity of the liquid storage chamber 22 can also effectively meet the requirements, and the structure of the floor brush is more compact.

[0080] Furthermore, in one embodiment of the present disclosure, the distance between axis a and axis b ranges from 10 mm to 35 mm. When the distance between axis a and axis b ranges from 10 mm to 35 mm, it can ensure that there is a certain distance between the front edge of the liquid storage chamber 22 and the front edge of the brush cover 23, which can not only ensure the capacity of the liquid storage chamber 22, but also the layout is more reasonable.

[0081] like Figure 3 As shown, in one embodiment of the present disclosure, the vertical center axis of the roller brush 3 in the radial direction is recorded as axis m, and the axis a, axis b, axis m and axis c are configured to be arranged in sequence from front to back. Among them, axis m is a straight line perpendicular to the working surface and passing through the center of the roller brush 3. Since the axis a, axis b, axis m and axis c are arranged in sequence from front to back, it can be ensured that the liquid storage chamber 22 of the present disclosure can cover from the rear of the roller brush 3 to the front half of the roller brush 3. Among them, the liquid storage chamber 22 is located in the front half of the roller brush 3, will not protrude too far forward, and can also ensure a large capacity.

[0082] like Figure 3 and Figure 8As shown, in one embodiment of the present disclosure, an arcuate surface 221 is formed on the bottom surface of the front end of the liquid storage cavity 22, and the arcuate surface 221 is constructed to be partially located on the front side of the vertical center axis of the roller brush 3 and partially located on the rear side of the vertical center axis of the roller brush 3. The height of the front edge of the arcuate surface 221 is constructed to be lower than the height of the direct projection of the arcuate surface 221 on the vertical center axis of the roller brush 3. In this way, the horizontal tangent of the arcuate surface 221 located at the vertical center axis of the roller brush 3, the front edge of the liquid storage cavity 22 and the part of the arcuate surface 221 located in front of the vertical center axis of the roller brush 3 can enclose a first liquid storage area A, which can store part of the cleaning liquid, thereby increasing the capacity of the liquid storage cavity 22, and during the operation of the cleaning device, the user repeatedly pulls the cleaning device, and the cleaning liquid in the first liquid storage area A can be shaken out of the first liquid storage area A, and then flow to the water outlet valve 26 of the cleaning liquid tank 2 to be sprayed out.

[0083] Among them, Figure 3 and Figure 8 As shown, in one embodiment of the present disclosure, on the vertical plane of the floor brush assembly 10 of the present disclosure, the arc surface 221 of the liquid storage cavity 22 and the brush cover 23 are located on the same arc line.

[0084] Further, in one embodiment of the present disclosure, the distance between the axis b and the axis c is in the range of 27 mm to 56 mm. When the distance between the axis b and the axis c is in the range of 27 mm to 56 mm, it can effectively ensure that the liquid storage chamber 22 can extend forward a certain distance relative to the rear edge of the brush cover 23, thereby ensuring the capacity of the liquid storage chamber 22.

[0085] Specifically, Figure 8 As shown, in one embodiment of the present disclosure, the distance between axis b and axis c is 40 mm, the distance between axis a and axis b is 12.42 mm, and the height d1 of the orthographic projection of the bottom of the first liquid storage area A on the vertical center axis of the roller brush 3 is 3.72 mm. In this way, the amount of cleaning liquid in the first liquid storage area A will not be too much, thereby ensuring that the cleaning liquid in the first liquid storage area A can be finally utilized without waste or residue.

[0086] It is understandable that if Figure 8 As shown, the horizontal tangent of the protruding portion of the liquid storage chamber 22 located at the rear side of the arc surface 221, the portion of the arc surface 221 located at the rear side of the vertical center axis of the roller brush 3 and the section of the liquid storage chamber 22 located at the rear side of the arc surface 221 can enclose a second liquid storage area B. The second liquid storage area B can also be used to store part of the cleaning liquid, and during the operation of the cleaning device, the user repeatedly pulls the cleaning device, and the cleaning liquid in the second liquid storage area B can also be shaken out, and then flow to the water outlet valve 26 of the cleaning liquid tank 2 to be sprayed out.

[0087] like Figure 8As shown, in one embodiment of the present disclosure, the height of the front edge of the arc surface 221 is constructed to be higher than the height of the rear edge, the height of the front edge refers to the height of the front edge of the arc surface 221 from the working surface, and the height of the rear edge refers to the height of the rear edge of the arc surface 221 from the working surface. In this way, the bottom surface height of the first liquid storage area A will not be lower than the height of the rear edge of the arc surface 221, thereby making the depth of the first liquid storage area A lower, thereby reducing the difficulty of shaking out the cleaning liquid in the first liquid storage area A, so that the cleaning liquid in the first liquid storage area A can be finally utilized without waste and residue.

[0088] In another embodiment of the present disclosure, the front edge of the liquid storage chamber 22 is constructed to be located directly above the highest point of the roller brush 3, that is, the axis b and the axis m coincide. In this way, the liquid storage chamber 22 of the present disclosure can cover from the rear of the roller brush 3 to directly above the vertical center axis of the roller brush 3, and the aforementioned first liquid storage area A will not appear, thereby effectively avoiding the situation where cleaning liquid remains in the first liquid storage area A.

[0089] Specifically, in one embodiment of the present disclosure, the distance between axis b and axis c is 27 mm, and the distance between axis a and axis b is 27.42 mm, so that the front edge of the liquid storage chamber 22 is located directly above the highest point of the roller brush 3, that is, axis b and axis m coincide.

[0090] like Figure 1 As shown, in one embodiment of the present disclosure, a floor brush wheel 5 is further provided on the floor brush body 1, and the floor brush wheel 5 is configured to support the floor brush body 1 on the working surface, and the floor brush wheel 5 includes two first rollers 51 arranged side by side on the front side of the floor brush body 1 and two second rollers 52 arranged side by side on the rear side of the floor brush body 1. The two first rollers 51 and the two second rollers 52 can jointly support the floor brush assembly 10 on the working surface. Figure 3 As shown, the rear edge of the cleaning liquid tank 2 is marked as axis d, and the rear edge of the floor brush assembly 10 is marked as axis e. The distance between axis d and axis e is greater than 34 mm. In this way, ample space can be left for the arrangement of the second roller 52 to ensure that the wheel diameter of the second roller 52 can meet the requirements.

[0091] like Figure 7 and Fig. 9 As shown, in one embodiment of the present disclosure, a front end of the cleaning liquid tank 2 is provided with an anti-collision strip 25 perpendicular to the forward direction of the cleaning device, and the anti-collision strip 25 is configured to provide a buffer when the cleaning device collides with an obstacle located in the forward direction. By providing the anti-collision strip 25 on the cleaning liquid tank 2, a buffer can be provided when the cleaning device collides with an obstacle located in the forward direction, effectively preventing the box body 21 from being damaged by the collision with the obstacle.

[0092] like Figure 3As shown, the present disclosure provides a cleaning device, which includes a floor brush assembly, which includes a floor brush body 1, a roller brush 3 and a cleaning liquid tank 2, wherein the roller brush 3 is rotatably connected to the front side of the floor brush body 1 and is configured to rotate relative to the working surface to clean the working surface; the cleaning liquid tank 2 is detachably connected to the floor brush body 1, and the cleaning liquid tank 2 includes a box body 21 having a liquid storage chamber 22; wherein the side of the box body 21 adjacent to the roller brush 3 is configured to extend to the top of the roller brush 3; the liquid storage chamber 22 is configured to extend forward from the rear side of the roller brush 3 and cross the vertical center axis of the roller brush 3, so that the liquid storage chamber 22 covers both sides of the vertical center axis of the roller brush 3 in the radial direction. In this way, the extension length of the liquid storage chamber 22 can be effectively increased, and then the capacity of the liquid storage chamber 22 can be increased, so that the cleaning device of the present disclosure can be used in a whole house cleaning process without frequently adding cleaning liquid to the cleaning liquid tank 2, thereby effectively reducing the number of times the user adds cleaning liquid, thereby effectively improving the user's use experience.

[0093] like Figure 8 As shown, the present disclosure provides a floor brush assembly, which includes a floor brush body 1, a roller brush 3 and a cleaning liquid tank 2, wherein the roller brush 3 is rotatably connected to the front side of the floor brush body 1 and is constructed to rotate relative to a working surface to clean the working surface; the cleaning liquid tank 2 is detachably connected to the floor brush body 1, and the cleaning liquid tank 2 includes a box body 21 having a liquid storage chamber 22; an arcuate surface 221 is formed on the front bottom surface of the liquid storage chamber 22, and the arcuate surface 221 includes a first arcuate surface located in front of the highest point of the arcuate surface 221 and a second arcuate surface located behind the highest point of the arcuate surface 221, the first arcuate surface is constructed to enclose a partial side wall of a first liquid storage area A; the second arcuate surface is constructed to enclose a partial side wall of a second liquid storage area B; the front end of the first arcuate surface is higher than the rear end of the second arcuate surface.

[0094] Further, such as Figure 8 As shown, in one embodiment of the present disclosure, the height of the positive projection of the first curved surface on the vertical central axis where the highest point is located is lower than the height of the positive projection of the second curved surface on the vertical central axis where the highest point is located, so that the depth d1 of the first liquid storage area A is lower than the depth d2 of the second liquid storage area B.

[0095] In this way, since the depth d1 of the first liquid storage area A is lower than the depth d2 of the second liquid storage area B, the depth of the first liquid storage area A is lower, thereby reducing the difficulty of shaking out the cleaning liquid in the first liquid storage area A, so that the cleaning liquid in the first liquid storage area A can be finally utilized without waste and residue.

[0096] It is understandable that if Figure 3 As shown, the vertical center axis at the highest point of the arc surface 221 can coincide with the vertical center axis in the radial direction of the roller brush 3 .

[0097] Furthermore, in one embodiment of the present disclosure, the arc surface 221 is configured to be located above the roller brush 3; the height of the orthographic projection of the second arc surface on the vertical central axis where the highest point is located is lower than the radius of the roller brush 3; the depth of the second liquid storage area B ranges from 3mm to 30mm, and the diameter of the roller brush 3 ranges from 30mm to 65mm. In this way, the difficulty of shaking out the cleaning liquid in the second liquid storage area B can be effectively reduced, so that the cleaning liquid in the second liquid storage area B can also be finally used without being wasted.

[0098] Specifically, in one embodiment of the present disclosure, the depth d1 of the first liquid storage area A is 3.72 mm, the depth of the second liquid storage area B is 21.03 mm, and the diameter of the roller brush 3 is 51 mm. In this way, the depths of the first liquid storage area A and the second liquid storage area B are relatively reasonable, which can effectively increase the capacity of the liquid storage cavity 22 without causing waste.

[0099] Further, in one embodiment of the present disclosure, the cleaning liquid tank 2 further includes a brush cover 23 integrally arranged at the front side of the bottom of the tank body 21, the brush cover 23 is configured to be located above the roller brush 3, and has a brush groove 24 adapted to the roller brush 3; the longitudinal axis of the front edge of the liquid storage chamber 22 is recorded as axis b, the longitudinal axis of the rear edge of the brush cover 23 is recorded as axis c, and the distance between axis b and axis c is not less than the radius of the roller brush 3. Since the distance between axis b and axis c is not less than the radius of the roller brush 3, it can be effectively ensured that the liquid storage chamber 22 can extend forward from the rear side of the roller brush 3 and cross the vertical center axis of the roller brush 3, so that the liquid storage chamber 22 covers both sides of the vertical center axis of the roller brush 3 in the radial direction, so as to increase the capacity of the liquid storage chamber 22.

[0100] Application Scenario

[0101] In an embodiment of the present disclosure in which the cleaning device is a handheld floor scrubber, when the user uses the floor scrubber for cleaning, the user can push the floor scrubber to move on the work surface and clean the work surface.

[0102] In the cleaning device of the present disclosure, since the cleaning liquid tank 2 of the present disclosure is arranged on the floor brush assembly 10, the weight of the body 20 can be reduced, so that the force required for the user to hold the body 20 is smaller, and the convenience of the user pushing and pulling the body 20 is improved. In addition, the cleaning liquid tank 2 is arranged on the floor brush assembly 10, which can effectively increase the downward pressure of the floor brush assembly 10, thereby improving the cleaning effect of the roller brush 3 on the working surface. The cleaning liquid tank 2 of the present disclosure can act as a brush cover 23 to prevent the splashing of sewage generated when the roller brush 3 rotates, saving the number of parts and material costs, and can integrate the removal and placement actions of the cleaning liquid tank 2 and the brush cover 23 into one, thereby reducing the number of times the user disassembles and assembles parts, thereby reducing the frequency of user removal and placement.

[0103] Moreover, since one side of the box body 21 adjacent to the roller brush 3 extends to above the roller brush 3, and the positive projections of the liquid storage chamber 22 and the roller brush 3 on the working surface at least partially overlap, the extension length of the liquid storage chamber 22 can be effectively increased, thereby increasing the capacity of the liquid storage chamber 22, so that the cleaning device of the present invention can be used in a whole-house cleaning process without frequently adding cleaning liquid to the cleaning liquid tank 2, thereby effectively reducing the number of times the user adds cleaning liquid, thereby effectively improving the user experience.

[0104] Moreover, an arcuate surface 221 is formed on the bottom surface of the front end of the liquid storage chamber 22. The arcuate surface 221 is constructed to be partially located on the front side of the vertical center axis of the roller brush 3 and partially located on the rear side of the vertical center axis of the roller brush 3. The height of the front edge of the arcuate surface 221 is constructed to be lower than the height of the direct projection of the arcuate surface 221 on the vertical center axis of the roller brush 3. In this way, the horizontal tangent of the arcuate surface 221 located at the vertical center axis of the roller brush 3, the front edge of the liquid storage chamber 22 and the part of the arcuate surface 221 located in front of the vertical center axis of the roller brush 3 can enclose a first liquid storage area A, which can store part of the cleaning liquid, thereby increasing the capacity of the liquid storage chamber 22.

[0105] In this way, during the operation of the cleaning device, as the user repeatedly pulls the cleaning device, part of the cleaning liquid in the liquid storage chamber 22 will flow between the main part of the liquid storage chamber 22 and the first liquid storage area A. However, as the cleaning liquid in the liquid storage chamber 22 continues to decrease, it becomes increasingly difficult for the cleaning liquid to flow from the main part of the liquid storage chamber 22 to the first liquid storage area A. However, the cleaning liquid in the first liquid storage area A can still easily flow to the main part of the liquid storage chamber 22 due to shaking, thereby ensuring that when the cleaning liquid in the liquid storage chamber 22 is fully utilized, no cleaning liquid will remain in the first liquid storage area A.

[0106] 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 marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
