Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in FIG. 1, the present invention provides a floor brush 1 comprising a working part 11 and a connecting part 12 fixed as a whole, the floor brush 1 having opposite front and rear parts, the connecting part 12 in this embodiment being disposed at the rear part of the working part 11. The working part 11 consists of a floor brush main body 111 and a cleaning liquid tank 112 which is detachably arranged on the floor brush main body 111; wherein, the floor brush main body 111 can be in direct contact with the surface to be cleaned for cleaning the garbage on the surface to be cleaned, and a suction port 211 for sucking the garbage is constructed on the floor brush main body 111; the cleaning liquid tank 112 belongs to a cleaning liquid supply assembly, which stores cleaning liquid such as clean water, cleaning agent or nursing agent, and the cleaning liquid is pumped from the cleaning liquid tank 112 to the surface to be cleaned in a use scene in which the surface to be cleaned needs to be wetted.

Through installing the cleaning solution case in the scrubbing brush main part, can make things convenient for the handheld operation pole body of user and clean bed bottom space. Meanwhile, by adopting the structure, a longer cleaning solution water pipe is not required to be arranged, so that the spraying response is quicker; the whole weight of the floor brush can be increased, so that the force of pressing the floor brush down to the ground is increased, and the cleaning effect is improved.

The inclusion of the cleaning liquid tank 112 increases the size of the working portion 11, and thus the working portion cannot be easily pulled to a bed bottom, a corner, or the like for cleaning. Referring to fig. 2 and 3, in order to solve the above problems, 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 270mm; 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 the maximum length thereof, the efficiency of the working part 11 in cleaning corner positions is improved. However, when the maximum length of the working part 11 is too small, the cleaning efficiency in the open area is low, and it is preferable that the maximum length of the working part is 250 to 270mm in consideration of the above.

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 of the maximum width b to the maximum length a of the working part ranges from 0.5 to 0.7; therefore, the working part can be made to have the smallest size on the premise of satisfying the stable supporting function and the mounting carrier function of the working part.

To ensure that the cleaning liquid supply assembly can wet 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; in this way, when the cleaning liquid tank capacity is preset, the cleaning liquid tank can be limited not to occupy excessive space, and the overall compactness of the working part 11 is improved.

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.

In one embodiment of the present disclosure, in order to fully utilize the installation space of the floor brush main body 111 and match the basic shape of the working portion 11, the projection of the cleaning liquid tank in the height direction is also substantially rectangular, and the maximum length d of the cleaning liquid tank is substantially consistent with the maximum length a of the working portion. 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; therefore, the circumferential limiting function of the mounting shell on the cleaning liquid tank is kept, and the upper structure of the cleaning liquid tank can be expanded to be basically consistent with the maximum length of the working part. Meanwhile, the length of the cleaning liquid tank 112 is designed to be as large as possible, so that the height and the width of the cleaning liquid tank 112 can be conveniently adjusted, and the installation position of the parts on the working part 11 can be conveniently designed.

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.

Further, the rear end of the cleaning liquid tank 112 forms at least 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 so as to avoid components located in the front portion of the brush main body 111.

In a specific application scenario, the floor brush main body 111 includes an installation shell 1111, an upper shield 1112 and a rolling brush 1113; the rolling brush 1113 is rotatably arranged at the front part of the mounting shell 1111 and is used for rolling and scrubbing the surface to be cleaned, and the upper baffle 1112 is arranged at the upper part of the rolling brush 1113 and is used for shielding at least part of the rolling brush and used as a mounting carrier; meanwhile, a cleaning liquid tank 112 is provided at the rear of the upper shield cover 1112. Based on the above position setting, the structure of the working part 11 is more compact, the space utilization rate is high, and the working part is beautiful and practical.

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 cover 1112 are arranged separately, so that the cleaning liquid tank 112 can be taken out and filled with cleaning liquid conveniently, and the problem is solved.

To further ensure that the working portion 11 can smoothly extend into the bed bottom region, the top of the working portion 11 should have as few projections 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.

As an embodiment of the present application, the upper shield 1112 is detachably connected to the mounting case 1111, which can facilitate cleaning and disassembling 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.

Referring to fig. 4 and 7, further, the mounting case 1111 includes a bottom case 21 and a top cover 22, and a floor brush mounting cavity 210 is formed between the bottom case 21 and the top cover 22; the above-mentioned suction port 211 is constructed at the front side of the bottom casing 21 and at the rear of the roll brush 1113; a floor brush passage 23 is provided in the floor brush installation chamber 210 in fluid communication with the suction port 211. In the cleaning process, the garbage on the surface to be cleaned is rubbed by the rolling brush 1113 and sucked away through the suction port 211, and is continuously guided and conveyed by the floor brush channel 23.

Since the floor brush channel 23 occupies a certain height in the floor brush installation cavity 210, it is necessary to define the height of the cleaning liquid tank 112 at the upper portion of the floor brush installation cavity 210 to avoid the height of the working portion 11 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.

Referring to fig. 6 and 7, still further, a receiving groove 220 is formed at an upper portion of the top cover 22, and the cleaning liquid tank 112 is detachably mounted in the receiving groove 220; 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; wherein, the lower part of the cleaning liquid tank 112 is used for limiting and installing, and the slightly longer upper part is beneficial to expanding the capacity of the cleaning liquid tank 112.

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 raised edge 221 is thin, the strength is poor, and the cleaning liquid tank 112 is difficult to be effectively limited; 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.

As an embodiment of the present application, the cleaning solution tank 112 may be connected to the mounting case 1111 through a locking structure, a buckling structure, and the like known to those skilled in the art, but the above-mentioned connecting structure needs more space and 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. Referring to fig. 4, 5 and 9, in particular, a first iron body 1124 may be fixed at the bottom of the cleaning liquid tank 112, and a first magnet 214 capable of generating a suction force with the first iron body 1124 is fixed in the floor brush installation cavity 210; thus, not only the space occupation of the connection structure is reduced, but also the connection structure is hidden, so that the structure of the working part 11 is more compact and beautiful. The magnetic 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 be magnetically attracted.

Further, the bottom of the cleaning liquid tank 112 may be further provided with a first liquid nozzle 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 which can realize liquid conduction/interception through pulling and inserting actions in any one of the prior art, and is not limited in the application.

It should be noted that the maximum height, the maximum width, and the maximum length of the cleaning liquid tank described above 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.

Referring to fig. 4, the cleaning liquid supply assembly further includes a nozzle 1120 and a pump 1121, the pump 1121 is used to pump the cleaning liquid from the cleaning liquid tank 112 to the nozzle 1120, and the nozzle 1120 serves as an output end of the cleaning liquid supply assembly to spray the cleaning liquid onto the floor surface to be cleaned, thereby performing a cleaning and/or care function for the floor surface. Specifically, the pump 1121 is disposed in the floor brush installation cavity 210, and is disposed at one side of the floor brush channel 23 along the length direction of the floor brush; the nozzle 1120 is disposed on the upper flap 1112.

Referring to fig. 6, in order to further secure the capacity of the cleaning liquid tank 112, the present application defines that the top end of the pump 1121 is higher than the lowest surface in the holding tank 220; that is, the bottom surface of the receiving groove 220 is configured with a first protrusion 2203 capable of at least partially receiving the pump 1121; referring to fig. 5, correspondingly, the bottom of the cleaning liquid tank 112 is configured with a first concave portion (not shown in the figure) for avoiding the first convex portion 2203. In addition, the present application defines that the top end of the floor brush channel 23 is higher than the lowest surface in the receiving groove 220, i.e. the bottom surface of the receiving groove 220 is configured with a second protrusion 2204 capable of at least partially receiving the floor brush channel 23; correspondingly, the bottom of the cleaning liquid tank 112 is configured with a second recess (not shown) for avoiding the second protrusion 2204. It will be understood that, in order to ensure the pumping amount of the cleaning liquid and the transporting amount of the garbage, the pump 1121 and the floor brush channel 23 should be at a certain height, respectively, and if the bottom surface of the holding tank 220 is constructed substantially as a plane, the height of the plane depends on which of the pump 1121 and the floor brush channel 23 is higher at the top end; this, undoubtedly, sacrifices some space available for expanding the capacity of the cleaning liquid tank. Based on the above arrangement, the cleaning liquid tank 112 and the floor brush main body 111 can be limited in height, so that the cleaning liquid tank has sufficient capacity, the structure of the working part 11 is more compact and practical, and the floor brush is convenient for a user to use in a space with limited height, such as a bed bottom. 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.

In one specific embodiment, the mounting housing 1111 is configured with a second fluid spigot 11211 and the upper cover 1112 is configured with a second fluid socket 11121 configured to form a valve assembly with the second fluid spigot 11211.

More 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.

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 is disposed on the other side of the floor brush channel 23 along the length direction of the floor brush; in another embodiment, the motor 311 may be disposed inside the rolling brush 1113, so that the size of the working part 11 can be further optimized and the compactness thereof can be improved.

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 supporting 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 plate 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 gear box 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 casing 21 along the length direction thereof; however, when the roll brush 1113 is mounted again, there occurs a problem that the connection post 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 coupling post 3121 can be smoothly inserted into the coupling 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 arranged on the other side of the bottom case 21, and is used for rotatably supporting the rolling brush 1113 and limiting the end part; 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 with and inserted into the limiting groove 414 is formed in the side plate 213.

Specifically, a supporting 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 supporting sleeve 42 through a snap 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 constructed 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 opposite to the bottom case 21, a pulling block 411 is installed in the concave portion 410, and a user can conveniently detach and install the supporting component 4 by pinching the pulling block 411 with his hand. And the pulling block 411 is entirely disposed 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 opposite to the bottom case 21, thereby not affecting the maximum length of the working portion 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 1.5mm; 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 1.5mm. 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.

The fluid in the application can be clean airflow or airflow wrapped with garbage; the garbage is at least one of dust, solid garbage (such as cigarette end, paper sheet, rice grain, etc.), and dirty liquid (such as orange juice, dirty water, clear water, egg liquid, etc.).

Specifically, when the fluid flows in the dirt storage tank 7 and the dustcup assembly 61, the mixed fluid of gas, dust and/or liquid is subjected to first-stage gas, dust and/or liquid separation by the dirt storage tank 7; dust and/or liquid is stored in the dirt storage tank 7, the fluid after the first stage of separation flows into the dust cylinder assembly 61 from the dirt storage tank 7 for the second stage of dust-air separation, and the separated clean air is discharged from the power assembly 62.

Certainly, when clearing up rubbish in less space, the user can directly use after independently dismantling handheld dust catcher 6, makes cleaning device's use scene more diversified. As is well known to those skilled in the art, under the suction force of the power assembly 62, fluid enters the dustcup assembly 61 from the inlet 610 of the hand-held cleaner for dust-air separation, and the separated clean air is exhausted from the power assembly 62.

As an embodiment of the present application, the main body 5 is provided with a first locking structure 92 for independently locking/unlocking the handheld dust collector 6 and a second locking structure 91 for independently locking/unlocking the dirt storage tank 7, so that the handheld dust collector 6 and the dirt storage tank 7 can be independently detachable; the first locking structure 92 and the second locking structure 91 may adopt a locking structure, a buckling structure, etc. known to those skilled in the art, and are not further limited in this application.
