Referring to fig. 1, 4, 5 and 9, the present invention provides a floor brush 1, comprising a working part 11, the working part 11 comprising a floor brush main body 111 and a cleaning liquid tank 112 detachably mounted on the floor brush main body 111; the floor brush body 111 can be in direct contact with a surface to be cleaned for cleaning garbage on the surface to be cleaned, and the cleaning liquid tank 112 is contained in the cleaning liquid supply assembly and stores cleaning liquids such as clean water, cleaning agents or nursing agents.

Further, the floor brush main body 111 includes a mounting case 1111 and a roll brush 1113; the rolling brush 1113 is rotatably disposed at the front of the mounting housing 1111 for rolling-scrubbing the surface to be cleaned.

A suction port 211 for sucking in the garbage is formed at the front of the mounting case 1111, and the suction port 211 is located at the rear side of the roll brush 1113; the floor brush main body 111 is provided with a floor brush channel 23 which is communicated with the suction port 211 in a fluid mode, and in the cleaning process, the garbage sucked through the suction port 211 is continuously guided and conveyed through the floor brush channel 23.

As an embodiment of the present application, the cleaning liquid tank 112 may be connected to the mounting shell 1111 through a locking structure, a buckling structure, etc. known to those skilled in the art, but the above-mentioned connecting structure needs a large space, so that the overall size of the working portion 11 is increased, and the connecting structure needs to be disposed at a conspicuous position; from this, it is fixed with the installation shell that preferred cleaning solution case passes through magnetism in this application and inhales the structure, does benefit to the whole size of control work portion.

Specifically, a first iron body 1124 may be fixed on the cleaning liquid tank 112, and a first magnet 214 capable of generating an attractive force with the first iron body 1124 is fixed in the mounting shell 1111; thus, the space occupation of the connection structure is reduced, and the connection structure is hidden, so that the structure of the working part 11 is more compact and beautiful. The magnetic attraction structure can be realized by interchanging the positions of the first iron body 1124 and the first magnet 214 and setting the two magnets to attract the magnet.

However, articles which can be magnetically attracted (such as iron taps, fruit knives and the like) are used in many places in our living environment; in the embodiment in which the cleaning liquid tank 112 is provided with the magnet, when the cleaning liquid tank 112 is taken out from the mounting case, the magnet at the bottom thereof is easily attracted to the living things, thereby affecting the regular use process of the user. Therefore, the present application preferably fixes the first iron body 1124 to the cleaning liquid tank 112, and fixes the first magnet 214 to the mounting case 1111.

As an embodiment of the present application, the number of the first iron bodies 1124 is configured to be two, and the two first iron bodies 1124 are symmetrically disposed at the bottom of the cleaning liquid tank 112; based on this structure, both sides of cleaning liquid tank 112 can be stably connected with the mounting case under the action of magnetic force.

Specifically, the bottom of the cleaning liquid tank 112 is configured with a dimple (not shown) recessed toward the inner space thereof, and the first iron body 1124 is fixed in the dimple by a bolt; when using first iron body 1124 for a long time, the rust ization can take place, and above-mentioned structure can realize that first iron body 1124 is convenient removable, the later maintenance of being convenient for.

In an embodiment of the present invention, the mounting case 1111 includes a bottom case 21 and a top cover 22, a floor brush mounting cavity 210 is formed between the bottom case 21 and the top cover 22, and the floor brush channel 23 is disposed in the floor brush mounting cavity 210.

As shown in fig. 9, further, a support column (not shown) is formed on bottom case 21, a recess is formed on the top of the support column, and first magnet 214 is disposed in the recess; in the assembled state of the bottom case 21 and the top cover 22, the top cover 22 can define that the first magnet 214 does not come out of the notch. It is understood that the first magnet 214 may be secured in the recess by interference press fit, gluing, welding, etc., or may be disposed in the recess with a gap; since the recess upper side is open, the top cover 22 can restrict the displacement of the first magnet 214 from the upper side when the bottom case 21 and the top cover 22 are assembled into the mounting case 1111; even if the first magnet 214 is placed in the recess with shaking, it will not be removed from the recess under the limit action of the top cover 22.

Since the cleaning liquid tank 112 approaches the first magnet 214 from the top cover 22, the closer the first magnet 214 is to the top cover 22, the better the magnetic attraction effect; therefore, the present application preferably has a maximum distance between the first magnet 214 and the top cover 22 of not more than 5mm, and further preferably has the first magnet 214 and the top cover 22 closely arranged.

As an embodiment of the present application, the floor brush main body 111 further includes an upper cover 1112, and at least a portion of the upper cover 1112 is disposed on an upper side of the rolling brush 1113 for shielding the rolling brush. Based on the above position setting, the structure of the working portion 11 can be made more compact, and the space utilization rate is high, and the structure is beautiful and practical. Further, a cleaning liquid tank 112 is provided on the rear side of the upper shield cover 1112.

In the prior art, the cleaning solution tank 112 and the upper baffle 1112 are usually arranged integrally, and the cleaning solution tank 112 and the upper baffle 1112 are required to be taken down together when cleaning solution is added, so that the operation of a user is inconvenient; the cleaning liquid tank 112 and the upper baffle 1112 are separately arranged, so that the cleaning liquid tank 112 can be taken out and filled with cleaning liquid conveniently, and the problem is solved.

As an embodiment of the present application, the upper shield 1112 is detachably connected to the mounting case 1111, which can facilitate cleaning and dismounting the roller brush 1113; compare the prior art with the integrative setting of cleaning fluid tank 112 and last fender lid 1112, this application is through setting up cleaning fluid tank 112 and the components of a whole that can function independently of last fender lid 1112, go up fender lid 1112 and detachably connect on installation shell 1111, has further optimized the structure of work portion 11, matches user's use habit more. It should be noted that if the width of the upper blocking cover 1112 is too small, the beneficial effects of cleaning, dismounting and mounting the roller brush are difficult to be fully embodied. Therefore, the ratio of the maximum width e of the cleaning liquid tank to the maximum width b of the working part is preferably in the range of 0.5 to 0.7; by defining the maximum width of the cleaning liquid tank 112, sufficient installation space is provided for the upper flap 1112, making it more meaningful to provide the upper flap 1112.

Further, the rear end of the cleaning liquid tank 112 is configured at least as a part of the rear end of the working portion 11, that is, the cleaning liquid tank 112 is disposed as far rearward as possible to avoid components (such as a top cover) located at the front of the brush main body 111.

As an embodiment of the present application, in order to ensure that the working portion 11 can smoothly extend into the bed bottom region, the top of the working portion 11 should have no protruding portion as much as possible; that is, the top surface of the cleaning liquid tank 112 and the top surface of the upper cover 1112 are substantially horizontal, and the top surfaces are substantially flat to avoid a step surface.

During cleaning, the two sides of the working part 11 along the length direction are easy to collide with obstacles; in order to reduce the impact caused by the collision, the upper shield 1112 and the cleaning solution tank 112 at the upper part of the working part 11 are provided with rounded corners or chamfers at both sides along the length direction of the floor brush.

Referring to fig. 4-6, the cleaning liquid supply assembly further includes a nozzle 1120 and a pump 1121; a pump 1121 is provided in the brush body 111 for pumping the cleaning liquid from the cleaning liquid tank 112 to the nozzle 1120, the nozzle 1120 serving as an output end of the cleaning liquid supply assembly for spraying the cleaning liquid onto the floor to be cleaned, thereby functioning to clean and/or care for the floor; specifically, the nozzle 1120 is mounted on the upper shield 1112.

Referring to fig. 7, as an embodiment of the present application, the bottom of the cleaning liquid tank 112 may be provided with a first liquid spigot 1122 and a positioning block 1123; the first liquid spigot 1122 and the first liquid socket 2201 on the mounting shell 1111 can form a valve assembly, and when the first liquid spigot 1122 and the first liquid socket 2201 are plugged, cleaning liquid can flow out of the cleaning liquid tank; the positioning block 1123 can be inserted into the insertion hole 2202 in the mounting shell 1111 to play a positioning role. The valve assembly is an assembly for realizing liquid conduction/interception through a plugging action in any one of the prior art, and is not limited in the application. Further, first liquid spigot 1122 and positioning block 1123 are respectively arranged on two sides of cleaning liquid tank 112 along the length direction thereof, and both can function as plug connectors, so that the cleaning liquid tank is limited from two sides thereof.

Further, the mounting housing 1111 is configured with a second liquid spigot 11211, and the upper cover 1112 is configured with a second liquid insertion opening 11121 capable of forming a valve assembly with the second liquid spigot 11211; specifically, the pump 1121 has a pump inlet and a pump outlet, the pump inlet is in fluid communication with the first liquid inlet 2201 through a first conduit, the pump outlet is in fluid communication with the second liquid nozzle 11211 through a second conduit, and the second liquid inlet 11121 is in fluid communication with the nozzle 1120 through a third conduit 11122. Wherein the first and second conduits are disposed in the floor brush installation cavity 210, and the third conduit 11122 is disposed in the upper shield 1112; by providing two valve assemblies and arranging three conduits, an efficient flow guidance and individual detachability between the various components of the cleaning liquid supply assembly is achieved.

Based on the dispersed arrangement of the plurality of components in the cleaning liquid supply assembly, the installation positions of the plurality of components can be reasonably distributed, and the problem that the cleaning liquid supply assembly is centralized and the floor brush 1 is difficult to optimize in terms of height is avoided; that is, this arrangement also facilitates the brush extending into the bed bottom for cleaning.

Referring to fig. 5, in an embodiment, the number of the first iron bodies 1124 is configured to be more than two (i.e., a plurality of), and a plurality of first iron bodies 1124 are uniformly arranged around the outer circumference of the first liquid nozzle 1122; based on this structure, can guarantee first liquid spigot 1122 and first liquid socket 2201's connection stability, avoid its connection position infiltration to appear in the use to the sealed effect of play water has been strengthened. In this embodiment, when the number of the first iron bodies 1124 is two, the two first iron bodies 1124 are symmetrically disposed on both sides of the first liquid nozzle 1122.

As an embodiment of the present application, a receiving groove 220 is configured on the floor brush main body 111, and the cleaning liquid tank 112 is detachably mounted in the receiving groove 220; specifically, the receiving groove 220 is disposed at an upper portion of the top cover 22. Further, the pump 1121 and the floor brush passage 23 are disposed below the receiving groove 220, and at least one of a top end of the pump 1121 and a top end of the floor brush passage 23 is higher than a lowest surface in the receiving groove 220. Specifically, the present application is configured with a first protrusion 2203 capable of at least partially accommodating the pump 1121 and/or a second protrusion 2204 capable of at least partially accommodating the ground brush channel 23 at the bottom surface of the accommodating groove 220; correspondingly, the bottom of the cleaning liquid tank 112 is configured with a first concave portion for avoiding the first convex portion 2203 and/or a second concave portion for avoiding the second convex portion 2204. It will be understood that the pump 1121 and the floor brush passage 23 must be formed to have a certain height, respectively, in order to ensure the pumping amount of the cleaning liquid and the transferring amount of the garbage, and if the bottom surface of the accommodating groove 220 is substantially configured to be a plane, the height of the plane depends on which of the pump 1121 and the floor brush passage 23 has the higher top end; this undoubtedly sacrifices some space available for expanding the capacity of the cleaning liquid tank, thereby being disadvantageous in optimizing the overall height of the working portion 11.

It should be noted that the lowest surface in the receiving groove 220 refers to a substantially planar inner bottom of the receiving groove 220 engaged with the first protrusion 2203 and the second protrusion 2204.

By setting the top end 1121 of the pump and/or the top end of the floor brush passage 23 higher than the lowest surface in the housing groove 220, the height of the floor brush which is advantageous to be extended into the bed bottom can be obtained while the capacity of the cleaning liquid tank 112 is not reduced, so that the present situation of use can be effectively improved.

Further, the floor brush passage 23 and the pump 1121 are installed in the floor brush installation cavity 210, and the pump 1121 is disposed at one side of the floor brush passage 23 in the length direction of the floor brush, so that the space in the floor brush installation cavity 210 can be fully utilized.

Since the floor brush channel 23 occupies a certain height in the floor brush installation cavity 210, the height of the cleaning liquid tank 112 at the upper part of the floor brush installation cavity 210 needs to be limited, and the working part 11 is further prevented from being too large; in the present application, the ratio of the maximum height f of the cleaning liquid tank to the maximum height c of the working portion ranges from 0.4 to 0.7.

To facilitate the taking and placing of the cleaning liquid tank 112 in the holding tank 220, the cleaning liquid tank maximum height f is defined to be larger than the depth h of the holding tank. Based on the structure of the receiving groove 220, the top cover 22 is formed with the protruding edge 221 at both sides thereof in the lengthwise direction of the floor brush, and the cleaning liquid tank 112 is formed with the recess 1125 at both sides thereof to receive the protruding edge 221. With the above arrangement, the cleaning liquid tank 112 has a shape in which the upper part is slightly longer and the lower part is slightly shorter; the lower part of the cleaning liquid tank 112 is used for limiting and mounting, and the slightly longer upper part can facilitate the expansion of the capacity of the cleaning liquid tank 112 on the premise of not influencing the height of the working part.

In a specific application scene, limiting the depth of the groove; because, if the depth of the groove is smaller, the limit of the convex edge 221 to the groove 1125 is poorer, the cleaning liquid tank 112 is easy to shake; if the depth of the groove is too large, the extent of spatial expansion of the cleaning liquid tank located above the groove 1125 is limited, so that the significance of spatial expansion by this form is not great. Specifically, the ratio of the depth j of the groove to the maximum height f of the cleaning liquid tank ranges from 0.4 to 0.7.

In addition, the length g of the ledge 221 should also be limited; if the convex edge 221 is thin, the strength is poor, and the cleaning liquid tank 112 is difficult to limit effectively; if the convex edge 221 is thicker and the groove 1125 needs to be enlarged, the cleaning solution tank will sacrifice a certain capacity. Thus, the length g of the defining lip 221 is 7-10mm along the length of the floor brush.

In a specific application scenario, to ensure that the cleaning liquid supply assembly can spray a sufficient area, the volume of the cleaning liquid tank 112 is usually set to 0.35-0.6L; since the cleaning liquid tank 112 has a tank casing, its volume (required occupied space) must be larger than its capacity; the ratio of the capacity of the cleaning liquid tank to the volume of the cleaning liquid tank is not less than 0.35; thus, when the cleaning liquid tank capacity is preset, the cleaning liquid tank can be limited not to occupy excessive space, so that the overall compactness of the working part 11 is improved.

In one embodiment of the present disclosure, the maximum length d of the cleaning liquid tank is substantially equal to the maximum length a of the working portion in order to fully utilize the installation space of the floor brush main body 111. It can be understood that, along the length direction of the floor brush, the distance between both sides of the cleaning liquid tank 112 is substantially equal to the distance between both sides of the floor brush main body 111; thus, the length of the cleaning liquid tank 112 can be designed to be as large as possible, so that the height and width of the cleaning liquid tank 112 can be adjusted, and the mounting position of the component on the working part 11 can be designed conveniently.

It should be noted that the maximum height, the maximum width and the maximum length of the cleaning liquid tank refer to the height, the width and the length of the cleaning liquid tank body, and do not include the protruding portions of the first liquid nozzle 1122 and the positioning block 1123.

As shown in fig. 1, as an embodiment of the present application, the floor brush 1 further comprises a connecting portion 12 integrally fixed with the working portion 11, the floor brush 1 has a front portion and a rear portion opposite to each other, and the connecting portion 12 in the present embodiment is disposed at the rear portion of the working portion 11.

Referring to fig. 2 and 3, the present application defines that a projection of the working part 11 in a height direction thereof is substantially rectangular, and a maximum length a of the working part 11 is not more than 270 mm; compared with other shapes, the working part with the rectangular overlooking visual angle has large cleaning range and small occupied space in single push-pull, and can be conveniently provided with the connecting part 12 and the cleaning liquid tank 112; by defining its maximum length, the efficiency of the working part 11 in cleaning corner positions is improved. However, when the maximum length of the working portion 11 is too small, the cleaning efficiency in the open area is low, and it is preferable that the maximum length of the working portion is 250-.

In order to match the basic shape of the working part 11, the present application defines that the projection of the cleaning liquid tank in the height direction thereof is also substantially rectangular as an embodiment of the present application.

Referring to fig. 8, it should be noted that, since the cleaning liquid tank needs to have a necessary limiting structure and/or avoid other components (such as the connection portion 12) when being installed, the cleaning liquid tank cannot necessarily have a regular rectangular shape in a plan view. By substantially rectangular it is meant that both pairs of opposite edges have portions which are substantially parallel; in addition, it should be understood that the projection of the working portion in the height direction is substantially rectangular.

As an embodiment of the present application, the rear portion of the cleaning liquid tank 112 is configured with an avoidance port 1128; along the length direction of the cleaning liquid tank 112, extensions 1129 are formed on both sides of the avoidance port 1128. When the cleaning liquid tank 112 is installed, part of the connection portion 12 can be fitted in the escape port 1128; meanwhile, two extension portions 1129 are respectively located at both sides of the connection portion 12. Based on the structure, the cleaning liquid tank 112 not only realizes effective yielding of the connecting part 12, but also the connecting part 12 can realize a limiting effect on the cleaning liquid tank 112; due to the existence of the extension 1129 (capable of accommodating the cleaning liquid therein), excessive cleaning liquid accommodating space is not sacrificed due to the construction of the avoiding position, and the water storage amount of the cleaning liquid tank 112 can be maximized without increasing the overall size of the floor brush.

Referring to fig. 7, further, the rear side of the extension 1129 is configured with a smooth arc surface, which can smoothly connect with the top surface of the cleaning liquid tank 112; when water drops exist on the top surface of the cleaning liquid tank, the smooth cambered surface has the effect similar to an eave, namely, the water drops can be smoothly guided downwards. In addition, the smooth arc surface is formed on the rear side of the extending part 1129, so that the damage degree of the extending part 1129 and the damage degree of the extending part 1129 when the extending part collides with an obstacle can be reduced.

Still further, the front side of the upper flap 1112 is also configured with a rounded arc surface to form a substantially symmetrical structure with the rear side of the extension 1129.

The working part 11 not only serves as an upstream component for sucking garbage, but also supports components such as a machine body, a handle and the like by matching with the connecting part 12, and has the function of installing the cleaning liquid tank 112; thereby further limiting the maximum width of the working portion 11. Specifically, the ratio range of the maximum width b to the maximum length a of the working part is 0.5-0.7; therefore, the working part can be made to have the smallest size on the premise of meeting the stable supporting function of the working part and the function of the mounting carrier.

Further, to comprehensively define the size of the working portion 11, the ratio of the volume of the cleaning liquid tank to the volume of the working portion in the present application ranges from 0.3 to 0.6. Thus, the height of the working part 11 can be restricted under the condition of determining the length and the width of the working part, so that the floor brush 1 can conveniently extend into areas with limited height, such as a bed bottom, a sofa bottom and the like, for cleaning; further, the ratio of the maximum height c to the maximum length a of the working part is limited to be in the range of 0.25-0.55, so as to satisfy the cleaning performance, convenience and aesthetic property of the working part at the same time.

During cleaning operation, the rolling brush 1113 can rotate under the transmission action of the motor 311; in one embodiment, the motor 311 may be disposed in the floor brush installation cavity 210 and disposed at the other side of the floor brush channel 23 along the length direction of the floor brush, but the height dimension of the motor 311 may be disadvantageous to the design of the bottom surface of the accommodating groove 220; based on the foregoing, in another embodiment, the motor 311 may be disposed inside the rolling brush 1113, which can further optimize the size of the working part 11 and improve the compactness thereof.

In the embodiment in which the motor 311 is provided in the roll brush 1113, a first roll brush supporting portion is fixed to one side of the bottom chassis 21 for fixing the motor 311; the arm 212 is configured as a first rolling brush support portion extending forward in the width direction of the floor brush. One end of the motor 311 is fixed on the support arm 212 through the connecting sleeve 215, the other end of the motor 311 is connected with the gearbox 312, and the gearbox 312 directly acts on the rolling brush 1113 to drive the rolling brush to rotate.

Referring to fig. 9 and 10, in detail, the roll brush 1113 includes a brush cylinder 32 and bristles 33 fixed to the outer circumference of the brush cylinder 32; a partition plate 322 vertical to the length direction is fixed in the brush cylinder 32; wherein, a plurality of connecting grooves 3200 are uniformly formed on the partition 322, and a plurality of connecting columns 3121 which can be correspondingly inserted into the connecting grooves 3200 are formed on the output shaft of the transmission case 312; when the motor 311 is activated, the connection column 3121 can apply a force to the connection groove 3200 to realize the rotation of the driving roll brush.

More specifically, the connecting column 3121 extends outward in the radial direction of the transmission output shaft, and a larger number thereof results in better transmission stability of the roll brush 1113 and the transmission case 312, but increases the production cost accordingly. As a preference in the present embodiment, the number of the connecting columns 3121 and the connecting grooves 3200 are each configured to be three.

After cleaning, the rolling brush 1113 sometimes needs to be detached separately for cleaning; since the motor 311 and the transmission case 312 are disposed inside the brush cylinder 32, the rolling brush 1113 can only be pulled out from the bottom case 21 along the length direction thereof; however, when the roll brush 1113 is installed again, there occurs a problem that the connection column 3121 and the connection groove 3200 are not easily aligned, resulting in a poor user experience. To solve the problem, the connecting column 3121 in this embodiment is substantially cylindrical, and a fillet or chamfer 3221 is formed at the outer edge of the connecting groove 3200; based on the above structure, the substantially cylindrical connection post 3121 can be smoothly inserted into the connection groove 3200 along the round or chamfered corner in the process of inserting the roll brush 1113.

Further, a second rolling brush supporting part is detachably configured on the other side of the bottom case 21, and is used for rotatably supporting and limiting the end part of the rolling brush 1113; the support assembly 4 is herein configured as a second roller brush support.

The supporting component 4 comprises a cover plate part 41, and the cover plate part 41 is fixed with the mounting shell through a magnetic attraction structure; specifically, a second iron body 413 is arranged on one side of the cover member 41 facing the bottom shell 21, a side plate 213 is configured on the bottom shell 21, and a second magnet (not shown) is mounted on the side plate 213; in this way, the connection structure of the support assembly 4 is also hidden, which is advantageous for controlling the maximum length of the working part 11. Of course, the magnetic fixed supporting component 4 can also be realized by exchanging the second iron body and the second magnet or arranging two magnets.

Fixing the support member 4 by means of the magnetic attraction structure facilitates controlling the dimensions of the deck member 41 and the bottom case 21 in the length direction, resulting in optimizing the length ratio of the roll brush in the working portion. The ratio of the maximum length of the rolling brush to the maximum length a of the working part is not less than 0.9; therefore, when the rolling brush is pushed and pulled for cleaning once, the rolling brush can scrub the surface to be cleaned as much as possible, so that the difference between the scrubbing length (the maximum length of the rolling brush) and the maximum length of the working part is almost zero, the cleaning effect is improved, and the cleaning efficiency is improved.

In order to reinforce the connection relationship between the cover plate member 41 and the side plate 213 and prevent the support assembly 4 from rotating relative to the side plate 213, a limited portion of the cover plate member 41 is embedded in the side plate 213; meanwhile, in order to ensure that the cover member 41 is installed in place, a limiting groove 414 is formed in one side of the cover member 41 facing the bottom case 21, and a limiting block 2131 capable of being matched and inserted with the limiting groove 414 is arranged on the side plate 213.

Specifically, a support sleeve 42 is fixed on one side of the cover member 41 facing the bottom shell 21, and a first bearing 43 is mounted inside the support sleeve 42 through a clamp spring 431; a connecting rod 44 is fixedly inserted into the inner ring of the first bearing 43, and the other end of the connecting rod 44 is inserted onto the rotating sleeve 45 in an interference manner.

Referring to fig. 9 and 11, in addition, the connection sleeve 215 is mounted with a second bearing 2150; in a use state, the brush cylinder 32 is sleeved on the rotating sleeve 45 and the second bearing 2150, and the rotating sleeve 45 and the second bearing 2150 respectively support the right side and the left side of the rolling brush 1113; the rotational resistance of the roll brush 1113 is reduced by the two bearing members.

Referring to fig. 12 and 13, in order to prevent friction caused by the inconsistent rotation speed of the rolling brush 1113 and the rotating sleeve 45, a flange 451 is formed on the rotating sleeve 45, and a plurality of notches 450 are formed on the flange 451; meanwhile, a plurality of insertion blocks 321 are configured on the brush cylinder 32. In the use state, the insertion block 321 can be inserted into the notch 450 correspondingly, thereby ensuring that the pace of the circumferential rotation of the rolling brush 1113 and the rotating sleeve 45 is completely consistent. Further, the height of the flange 451 is set to be not less than the thickness of the brush pot 32, which corresponds to the sealing of one end of the brush pot 32 by the rotary sleeve 45, and can block the entrance of the garbage into the brush pot 32. The rotary sleeve 45 is provided with an annular groove along the circumferential direction thereof, and the sealing ring 46 is arranged in the annular groove and abuts against the inner wall of the brush barrel 32, thereby further enhancing the garbage blocking effect.

As an embodiment of the present application, a concave portion 410 is disposed on a side of the cover member 41 facing away from the bottom case 21, a pulling block 411 is installed in the concave portion 410, and a user can conveniently detach and mount the supporting component 4 by pinching the pulling block 411 with his hand. And the pulling block 411 is completely arranged in the recess 410, so that the pulling block 411 does not protrude out of the plane of the cover member 41 on the side back to the bottom case 21, thereby not influencing the maximum length of the working part 11 and not easily colliding with an obstacle.

Specifically, the pulling block 411 and the supporting sleeve 42 are connected together through bolts, screws and the like, so that the design of convenient disassembly is beneficial to cleaning and maintenance of subsequent parts. Further, a limiting sleeve 412 is constructed on the cover plate member 41, and the support sleeve 42 is inserted into the limiting sleeve 412 in an interference manner; based on this structure, can promote the installation stability of supporting sleeve 42, prevent to support that 42 relative apron spare 41 from taking place to rock to the rotatory dynamic balance performance of round brush 1113 has been guaranteed.

The rotating sleeve 45 can rotate relative to the cover plate 41, so a gap is required to be configured between the rotating sleeve and the cover plate, and hairs, silk floes and other filaments inevitably enter the rotating sleeve 45 through the gap in the cleaning process; in order to avoid the filament from winding around the first bearing 43, the rotary piece of the connecting rod 44, the side of the support sleeve 42 facing the rotary sleeve 45 is defined in this application with a flared portion 421. Preferably, the minimum distance between the flared part 421 and the rotating sleeve 45 along the height direction of the roller brush 1113 is not more than 1.5 mm; the minimum distance between the flared part 421 and the rotating sleeve 45 along the length direction of the roller brush 1113 is not more than 1.5 mm. The support sleeve 42 and the rotary sleeve 45 are arranged substantially coaxially, so that the two minimum distances are respectively the minimum distance between the outer edge of the flared portion 421 and one inner wall of the rotary sleeve 45, and the minimum distance between the right end of the flared portion 421 and the other inner wall of the rotary sleeve 45.
