[0002] To meet market demand, some vacuum cleaners now feature the ability to spray water onto the floor or floor brushes to enhance cleaning. However, the roller brush, when wiping away the sprayed water, can easily cause water stains in the crevices of the floor brush. Furthermore, existing floor brushes are not easily disassembled, making it difficult to thoroughly remove water stains and leading to bacterial growth over time. Additionally, because these floor brushes are relatively integrated, damage to any component during use can result in high maintenance or repair costs.

[0060] like Figures 1-9 As shown, the present invention provides a floor brush 1 for use in cleaning equipment, including a working part 11. The working part 11 includes a floor brush body 111 and a cleaning liquid tank 112 detachably installed on the floor brush body 111. The floor brush body 111 can directly contact the surface to be cleaned and is used to clean the garbage on the surface to be cleaned. The cleaning liquid tank 112 is included in the cleaning liquid supply component and stores cleaning liquid such as water, detergent or care agent inside.

[0061] As an embodiment of this application, the floor brush body 111 includes a mounting shell 1111, a roller brush 1113, and an upper cover 1112. The roller brush 1113 is used to roll and scrub the surface to be cleaned. It is rotatably mounted on the front of the mounting shell 1111, and the roller brush 1113 is detachably connected to the front of the mounting shell 1111 along the length direction of the floor brush 1. The upper cover 1112 can be used to cover the roller brush 1113. The upper cover 1112 is detachably connected to the upper part of the mounting shell 1111 along the height direction of the floor brush 1, and at least part of the upper cover 1112 is located on the upper side of the roller brush 1113 (that is, along the height direction of the floor brush, the projection of the upper cover 1112 and the projection of the roller brush 1113 intersect). The upper part of the mounting shell 1111 is constructed with a receiving groove 220, and the cleaning liquid tank 112 is detachably disposed in the receiving groove 220 along the height direction of the floor brush 1. Based on the above structure, the floor brush 1 has a high degree of disassembly, which not only makes it easy to thoroughly clean the floor brush and avoid the growth of bacteria, but also makes it convenient for users to repair or maintain local parts, reducing the cost of use.

[0062] like Figures 2-4As shown, in one embodiment of this application, the front two sides of the mounting shell 1111 are provided with vertical grooves 222 and fixing blocks 223, and the front of the fixing blocks 223 is provided with limit openings 2230; the upper cover 1112 includes a cover shell and an unlocking button 243 that is retractably configured in the cover shell by means of an elastic member 2433.

[0063] Furthermore, the lower part of the cover shell is provided with two vertical blocks 2414 that can be inserted into the two vertical slots 222, and the rear sides of the unlock button 243 are provided with locking blocks 2432; when the vertical blocks 2414 are inserted into the vertical slots 222, the elastic element 2433 pushes the unlock button 243 backward so that the locking blocks 2432 are inserted into the limiting port 2230; when the unlock button 243 is pressed forward, the elastic element 2433 is compressed, and the locking blocks 2432 are disengaged from the limiting port 2230, which is convenient for removing the upper cover 1112 along the height direction of the floor brush 1.

[0064] As an embodiment of this application, the fixing block 223 is configured as one side of the vertical groove 222 (i.e., one outer wall of the fixing block 223 is configured as one inner wall of the vertical groove 222), and a first locking arm 2221 is formed at the front of the vertical groove 222; the rear of the cover shell is configured with a slot 2413, the fixing block 223 can be inserted into the slot 2413, and the locking block 2432 is retractably configured in the slot 2413; the rear of the vertical block 2414 is configured with a second locking arm 24141.

[0065] In this embodiment, when the vertical block 2414 is inserted into the vertical slot 222, the fixed block 223 is inserted into the slot 2413, and the locking block 2432 is inserted into the limiting port 2230, and the first locking arm 2221 and the second locking arm 24141 abut against each other. Based on the above structure, the vertical block 2414 engaging with the vertical slot 222 and the fixed block 223 engaging with the slot 2413 can doubly limit the displacement of the upper cover 1112 relative to the mounting shell 1111 along the length direction of the floor brush. The first locking arm 2221 engaging with the second locking arm 24141 can limit the displacement of the upper cover 1112 relative to the mounting shell 1111 along the width direction of the floor brush. The locking block 2432 engaging with the limiting port 2230 can limit the displacement of the upper cover 1112 relative to the mounting shell 1111 along the height direction of the floor brush. Thus, the upper cover 1112 can be stably connected to the mounting shell 1111.

[0066] As an embodiment of this application, in order to facilitate the user to insert the cover 1112, the initial insertion end of the second card arm 24141 is configured with a first rounded corner or a first chamfer, one side of the slot 2413 is configured with a second rounded corner or a second chamfer 24130, and the bottom side of the card block 2432 is configured with a third rounded corner or a third chamfer 24321.

[0067] As one embodiment of this application, the cover shell includes a lower cover shell 241 and an upper cover shell 242, which can be disassembled and assembled by means of bolt connection, snap-fit ​​connection or other methods.

[0068] In this embodiment, the unlock button 243 includes a central portion 24 and two side portions 2431 symmetrically disposed on both sides of the central portion 24. Two locking blocks 2432 are correspondingly disposed on the rear side of the two side portions 2431. Correspondingly, the lower cover 241 is provided with two movable grooves 2410 for accommodating the two side portions 2431. The rear part of the movable grooves 2410 is provided with a through groove 2411 for the locking blocks 2432 to extend and retract. One end of the elastic member 2433 abuts against the side portion 2431, and the other end abuts against the inner wall of the movable groove 2410.

[0069] As an embodiment of this application, in order to reduce the shaking of the unlock button 243 during the extension and retraction process, the lower cover 241 is provided with a guide rib 2412 along the width direction of the floor brush, and the unlock button 243 is provided with a guide groove 2430; the guide rib 2412 is slidably engaged in the guide groove 2430, which can limit the amount of displacement of the unlock button 243 relative to the lower cover 241 along the length direction of the floor brush.

[0070] Furthermore, the unlock button 243 is mounted downwards along the height direction of the floor brush with the lower cover 241 attached; specifically, the guide groove 2430 is configured to be open at the bottom, and the guide rib 2412 is inserted into the guide groove 2430 through the bottom of the guide groove 2430. When the lower cover 241 and the upper cover 242 are engaged, the upper cover 242 can cover the side portion 2431 along the height direction of the floor brush, thereby limiting the amount of displacement of the unlock button 243 relative to the lower cover 241 along the height direction of the floor brush.

[0071] As an embodiment of this application, the mounting housing 1111 includes a bottom housing 21 and a top cover 22, with a floor brush mounting cavity 210 formed between the bottom housing 21 and the top cover 22.

[0072] Furthermore, the front of the mounting housing 1111 is formed with a suction port 211 for sucking up garbage, which is located on the rear side of the roller brush 1113; the floor brush mounting cavity 210 is provided with a floor brush channel 23 that is in fluid communication with the suction port 211. During the cleaning process, the garbage sucked up by the suction port 211 is continued to be guided by the floor brush channel 23.

[0073] As one embodiment of this application, the cleaning fluid tank 112 can be connected to the mounting shell 1111 by means of a locking structure, snap-fit ​​structure or the like known to those skilled in the art. However, the above-mentioned connection structure requires a lot of space, which will increase the overall size of the working part 11 and needs to be placed in a conspicuous position. Therefore, in this application, it is preferable to fix the cleaning fluid tank to the mounting shell by a magnetic structure, which is conducive to controlling the overall size of the working part.

[0074] Specifically, a first iron body 1124 can be fixed on the cleaning fluid 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. This not only reduces the space occupied by the connecting structure but also hides the connecting structure, making the structure of the working part 11 more compact and aesthetically pleasing. The magnetic attraction structure can also be achieved by interchangeing the positions of the first iron body 1124 and the first magnet 214, setting them as two magnets for magnetic attraction.

[0075] However, many items that can be magnetically attracted are used in our living environment (such as iron faucets, fruit knives, etc.); in embodiments where a magnet is installed on the cleaning liquid tank 112, when the cleaning liquid tank 112 is removed from the mounting shell, the magnet at its bottom can easily attract the magnetic attraction of everyday items, thus affecting the user's normal use. Therefore, this application preferably fixes a first iron body 1124 on the cleaning liquid tank 112 and fixes a first magnet 214 in the mounting shell 1111.

[0076] As an embodiment of this application, the number of first iron bodies 1124 is configured as two, and the two first iron bodies 1124 are symmetrically arranged at the bottom of the cleaning liquid tank 112; based on this structure, both sides of the cleaning liquid tank 112 can be stably connected to the mounting shell under the action of magnetic force.

[0077] Specifically, the bottom of the cleaning fluid tank 112 has a recess (not shown in the figure) that is recessed into its internal space, and the first iron body 1124 is fixed in the recess by bolts. When the first iron body 1124 is used for a long time, it may rust. The above structure can make the first iron body 1124 easy to disassemble and facilitate later maintenance.

[0078] like Figure 9 As shown in one embodiment of this application, a support column (not shown) is formed on the bottom shell 21, and a notch is formed at the top of the support column. The first magnet 214 is disposed in the notch. In the assembled state of the bottom shell 21 and the top cover 22, the top cover 22 can prevent the first magnet 214 from falling out of the notch. It is understood that the first magnet 214 can be fixed in the notch by means of interference fit, adhesive, welding, etc., or it can be placed in the notch intermittently. Since the upper side of the notch is open, when the bottom shell 21 and the top cover 22 are assembled into the mounting shell 1111, the top cover 22 can limit the displacement of the first magnet 214 from the top. Even if the first magnet 214 is placed in the notch with some wobbling, it will not fall out of the notch under the limiting action of the top cover 22.

[0079] Since the cleaning liquid tank 112 approaches the first magnet 214 from the direction of the top cover 22, it is obvious that the closer the first magnet 214 is to the top cover 22, the better the magnetic attraction effect. Therefore, this application preferably has a maximum distance of no more than 5mm between the first magnet 214 and the top cover 22, and it is even more preferable that the first magnet 214 and the top cover 22 are fitted together.

[0080] In one embodiment of this application, the cleaning fluid tank 112 is located on the rear side of the upper cover 1112; a handle 1127 is provided on the top of the cleaning fluid tank 112, the bottom of the handle 1127 is hollow, and a hand-holding space 1128 is constructed on the front side of the handle 1127, which is configured opposite to the unlocking button 243. Based on the above structure, the user can operate the handle 1127 or the unlocking button 243 through the hand-holding space 1128, improving the space utilization of the floor brush and achieving a convenient and practical effect.

[0081] During cleaning operations, the roller brush 1113 can rotate under the transmission of the motor 311. In one embodiment, the motor 311 can be set in the above-mentioned floor brush mounting cavity 210 and is arranged on one side of the floor brush channel 23 along the length direction of the floor brush. However, the height of the motor 311 may be unfavorable to the bottom surface design of the receiving groove 220. Based on the foregoing, in another embodiment, the motor 311 can be set inside the roller brush 1113, which can further optimize the size of the working part 11 and improve its compactness.

[0082] In an embodiment where the motor 311 is installed inside the roller brush 1113, a first roller brush support is fixed to one side of the bottom shell 21 for fixing the motor 311; in this application, the support arm 212 is constructed as the first roller brush support, which extends forward along the width direction of the brush. One end of the motor 311 is fixed to the support arm 212 via a connecting sleeve 215, and the other end of the motor 311 is connected to a gearbox 312, which directly acts on the roller brush 1113 to drive the roller brush to rotate.

[0083] Reference Figure 9 and Figure 10 Specifically, the roller brush 1113 includes a brush cylinder 32 and bristles 33 fixed on the outer periphery of the brush cylinder 32; a partition 322 perpendicular to its length direction is fixed inside the brush cylinder 32; wherein, a plurality of connecting grooves 3200 are uniformly constructed on the partition 322, and a plurality of connecting posts 3121 that can be correspondingly inserted into the connecting grooves 3200 are constructed on the output shaft of the gearbox 312; when the motor 311 is started, the connecting posts 3121 can apply force to the connecting grooves 3200 to drive the roller brush to rotate.

[0084] More specifically, the connecting posts 3121 extend radially outward along the output shaft of the gearbox. The more of them there are, the better the transmission stability of the roller brush 1113 and the gearbox 312, but the production cost will increase accordingly. As a preferred embodiment, the number of connecting posts 3121 and connecting grooves 3200 are both configured to be three.

[0085] After cleaning, the roller brush 1113 sometimes needs to be disassembled separately for cleaning. Since the motor 311 and gearbox 312 are located inside the brush cylinder 32, the roller brush 1113 can only be pulled out relative to the bottom shell 21 along its length. However, when reinstalling the roller brush 1113, the connecting post 3121 and the connecting groove 3200 are not easily aligned, resulting in a poor user experience. To solve this problem, in this embodiment, the connecting post 3121 is basically cylindrical, and the outer edge of the connecting groove 3200 is formed with rounded corners or chamfers 3221. Based on the above structure, during the insertion of the roller brush 1113, the basically cylindrical connecting post 3121 can be smoothly inserted into the connecting groove 3200 along the rounded corners or chamfers.

[0086] Furthermore, a second roller brush support is detachably configured on the other side of the bottom shell 21 for rotating support and end limiting of the roller brush 1113; in this application, the support assembly 4 is configured as the second roller brush support.

[0087] The support assembly 4 includes a cover plate 41, which is fixed to the mounting shell by a magnetic structure. Specifically, a second iron body 413 is provided on the side of the cover plate 41 facing the bottom shell 21, and a side plate 213 is constructed on the bottom shell 21. A second magnet (not shown in the figure) is installed on the side plate 213. In this way, the connection structure of the support assembly 4 is also hidden, which is beneficial to controlling the maximum length of the working part 11. Of course, by replacing the second iron body and the second magnet, or by setting two magnets, the magnetic fixation of the support assembly 4 can also be achieved.

[0088] The magnetic structure for fixing the support assembly 4 facilitates control over the length dimensions of the cover plate 41 and the bottom shell 21, resulting in an optimized proportion of the roller brush's length within the working section. This application specifies that the ratio of the maximum length of the roller brush to the maximum length a of the working section (i.e., the maximum length of the floor brush) is not less than 0.9. This ensures that during a single push-pull cleaning cycle, the roller brush can scrub as much of the surface as possible, making the scrubbing length (maximum roller brush length) nearly equal to the maximum length of the working section, thus improving cleaning effectiveness and efficiency.

[0089] To strengthen the connection between the cover plate 41 and the side plate 213 and prevent the support assembly 4 from rotating relative to the side plate 213, a portion of the cover plate 41 is embedded in the side plate 213. At the same time, to ensure that the cover plate 41 is installed in place, a limiting groove 414 is provided on the side of the cover plate 41 facing the bottom shell 21, and a limiting block 2131 that can be matched and inserted into the limiting groove 414 is provided on the side plate 213.

[0090] Specifically, a support sleeve 42 is fixed to the side of the cover plate 41 facing the bottom shell 21, and a first bearing 43 is installed inside the support sleeve 42 through a snap ring 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 interference-fitted into the rotating sleeve 45.

[0091] Reference Figure 9 and Figure 11 In addition, a second bearing 2150 is installed on the connecting sleeve 215; in use, the brush cylinder 32 is mounted on the rotating sleeve 45 and the second bearing 2150, and the rotating sleeve 45 and the second bearing 2150 support the right and left sides of the roller brush 1113 respectively; under the action of the two bearings, the rotational resistance of the roller brush 1113 is reduced.

[0092] Reference Figure 12 and Figure 13 To prevent friction caused by inconsistent rotational speeds between the roller brush 1113 and the rotating sleeve 45, a flange 451 is constructed on the rotating sleeve 45, with several notches 450 formed on the flange 451. Simultaneously, several insert blocks 321 are constructed on the brush cylinder 32. In use, the insert blocks 321 can be inserted into the notches 450, ensuring that the roller brush 1113 and the rotating sleeve 45 rotate in perfect unison. Furthermore, the height of the flange 451 is set to be no less than the thickness of the brush cylinder 32, effectively sealing one end of the brush cylinder 32 through the rotating sleeve 45, preventing debris from entering the brush cylinder 32. The rotating sleeve 45 has an annular groove along its circumference, and a sealing ring 46 is disposed in the annular groove and abuts against the inner wall of the brush cylinder 32, further enhancing the debris-blocking effect.

[0093] As one embodiment of this application, the cover plate 41 has a recess 410 on the side facing away from the bottom shell 21, and a pull block 411 is installed in the recess 410. The user can easily install and remove the support assembly 4 by squeezing the pull block 411. Moreover, all the pull blocks 411 are set in the recess 410, so that the pull blocks 411 will not protrude from the plane of the cover plate 41 facing away from the bottom shell 21, thereby not affecting the maximum length of the working part 11, and is less likely to bump into obstacles.

[0094] Specifically, the pull block 411 and the support sleeve 42 are connected together by bolts, screws, etc., which facilitates disassembly and subsequent cleaning and maintenance of parts. Furthermore, a limiting sleeve 412 is constructed on the cover plate 41, and the support sleeve 42 is interference-fitted into the limiting sleeve 412. Based on this structure, the installation stability of the support sleeve 42 can be improved, preventing the support sleeve 42 from shaking relative to the cover plate 41, thereby ensuring the rotational dynamic balance performance of the roller brush 1113.

[0095] The rotating sleeve 45 can rotate relative to the cover plate 41, therefore a gap is required between them. During cleaning, hair, lint, and other filamentous materials inevitably enter the rotating sleeve 45 through this gap. To prevent these filamentous materials from becoming entangled on the rotating parts of the first bearing 43 and the connecting rod 44, this application specifies that the support sleeve 42 has a flared portion 421 on the side facing the rotating sleeve 45. Preferably, the minimum distance between the flared portion 421 and the rotating sleeve 45 is no greater than 1.5 mm along the height direction of the roller brush 1113 and no greater than 1.5 mm along the length direction of the roller brush 1113. Since the support sleeve 42 and the rotating sleeve 45 are substantially coaxial, the two minimum distances are respectively the minimum distance between the outer edge of the flared portion 421 and one inner wall of the rotating sleeve 45, and the minimum distance between the right end of the flared portion 421 and the other inner wall of the rotating sleeve 45.

[0096] refer to Figure 5 , Figure 7 , Figure 8 As an embodiment of this application, the cleaning fluid supply assembly further includes a nozzle 1120 and a pump 1121; the pump 1121 is disposed in the floor brush body 111 and is used to pump the cleaning fluid from the cleaning fluid tank 112 to the nozzle 1120. The nozzle 1120 serves as the output end of the cleaning fluid supply assembly and is used to spray the cleaning fluid onto the floor to be cleaned, thereby cleaning and / or maintaining the floor; specifically, the nozzle 1120 is mounted on the upper cover 1112.

[0097] As an embodiment of this application, both the floor brush channel 23 and the pump 1121 are installed in the floor brush mounting cavity 210. The pump 1121 is arranged on one side of the floor brush channel 23 along the length direction of the floor brush, so that the space in the floor brush mounting cavity 210 can be fully utilized.

[0098] refer to Figure 16As one embodiment of this application, the bottom of the cleaning fluid tank 112 may be provided with a first liquid inlet 1122 and a positioning block 1123; wherein, the first liquid inlet 1122 can form a valve assembly with the first liquid inlet 2201 located on the mounting housing 1111, and when the two are inserted, the cleaning fluid can flow out from the cleaning fluid tank (i.e., the cleaning fluid flows from the first liquid inlet to the first liquid inlet); the positioning block 1123 can be inserted into the insertion hole 2202 in the mounting housing 1111 to play a positioning role. The above-mentioned valve assembly is any of the prior art components that realize liquid conduction / interception through insertion and removal actions, and is not limited in this application.

[0099] refer to Figure 5 As an embodiment of this application, a second liquid inlet 11211 is constructed on the mounting housing 1111, and a second liquid port 11121, which can form a valve assembly with the second liquid inlet 11211, is constructed on the upper cover 1112. Specifically, the pump 1121 has a pump inlet and a pump outlet. The pump inlet and the first liquid port 2201 are connected by a first conduit, the pump outlet and the second liquid inlet 11211 are connected by a second conduit 11212, and the second liquid inlet 11121 and the nozzle 1120 are connected by a third conduit 11122. The first and second conduits are disposed in the floor brush mounting cavity 210, and the third conduit 11122 is disposed in the upper cover 1112. By configuring two valve assemblies and arranging three conduits, effective flow can be achieved between multiple components of the cleaning fluid supply assembly, and each component can be individually detached.

[0100] By distributing the multiple components in the cleaning fluid supply assembly, the installation positions of the multiple components can be reasonably allocated, avoiding the difficulty in optimizing the height of the floor brush due to the concentration of the cleaning fluid supply assembly; in other words, this arrangement also allows the floor brush to reach under the bed for cleaning.

[0101] refer to Figure 8 In one embodiment, the number of first iron bodies 1124 is configured to be two or more, and the multiple first iron bodies 1124 are evenly arranged around the outer periphery of the first liquid nozzle 1122. Based on this structure, the connection stability between the first liquid nozzle 1122 and the first liquid inlet 2201 can be guaranteed, and water leakage at the connection point can be avoided during use.

[0102] In one embodiment of this application, the aforementioned receiving groove 220 is disposed on the upper part of the top cover 22. Further, the pump 1121 and the floor brush channel 23 are located below the receiving groove 220, with at least one of the top ends of the pump 1121 and the floor brush channel 23 being higher than the lowest surface within the receiving groove 220. Specifically, this application constructs 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 floor brush channel 23 on the bottom surface of the receiving groove 220; correspondingly, the bottom of the cleaning fluid tank 112 is constructed with a first recess 11261 for avoiding the first protrusion 2203 and / or a second recess 11262 for avoiding the second protrusion 2204. It is understandable that, in order to ensure the pumping volume of cleaning fluid and the conveying volume of waste, pump 1121 and floor brush channel 23 must reach a certain height. If the bottom surface of the receiving tank 220 is basically constructed as a plane, then the height of this plane depends on the one with the higher top of pump 1121 and floor brush channel 23. In this way, some space that can be used to expand the capacity of the cleaning fluid tank is undoubtedly sacrificed, which is not conducive to optimizing the overall height of the working part 11.

[0103] It is worth noting that the lowest surface in the aforementioned receiving groove 220 refers to the basically flat inner bottom of the receiving groove 220 that connects with the first protrusion 2203 and the second protrusion 2204.

[0104] By setting the top of the pump 1121 and / or the top of the floor brush channel 23 to be higher than the lowest surface inside the receiving tank 220, the floor brush height that is conducive to reaching under the bed can be obtained while ensuring that the capacity of the cleaning liquid tank 112 is not reduced, thereby effectively improving the current usage situation.

[0105] refer to Figure 6 As one embodiment of this application, the second conduit 11212 includes an inclined section connecting to the second liquid nozzle 11211 (the projection of this inclined section along the length of the floor brush is not vertical). Since the roller brush 1113 is disposed on the front side of the bottom shell 21 and is cylindrical, if the section of the second conduit 11212 connecting to the second liquid nozzle 11211 is constructed vertically, it will inevitably occupy more space in the bottom shell 21, which will affect the space occupied by the cleaning liquid tank 112 and even the overall size of the floor brush. Furthermore, this application constructs a third protrusion 2205 in the receiving groove 220 that can at least accommodate part of the inclined section; correspondingly, a third recess 11263 is constructed on the cleaning liquid tank 112 to avoid the third protrusion 2205.

[0106] Since the brush channel 23 occupies a certain height in the brush mounting cavity 210, it is necessary to limit the height of the cleaning fluid tank 112 located at the top of the brush mounting cavity 210 to further avoid the working part 11 from being too tall. In this application, the ratio of the maximum height f of the cleaning fluid tank to the maximum height c of the working part is in the range of 0.4-0.7.

[0107] To facilitate the placement and removal of the cleaning fluid tank 112 within the receiving groove 220, the maximum height f of the cleaning fluid tank is limited to be greater than the depth h of the receiving groove. Based on the structure of the receiving groove 220, protruding edges 221 are constructed on both sides of the top cover 22 along the length of the floor brush. Simultaneously, recesses 1125 are constructed on both sides of the cleaning fluid tank 112 to accommodate the protruding edges 221. With these configurations, the cleaning fluid tank 112 exhibits a shape that is slightly longer at the top and slightly shorter at the bottom. The lower part of the cleaning fluid tank 112 is used for positioning and installation, while the slightly longer upper part facilitates expanding the capacity of the cleaning fluid tank 112 without affecting the height of the working part.

[0108] In specific application scenarios, the depth of the groove should be limited. If the groove depth is too small, the restraint of the protruding edge 221 on the groove 1125 is poor, and the cleaning fluid tank 112 is prone to wobbling. If the groove depth is too large, the expansion range of the cleaning fluid tank space above the groove 1125 is limited, making this method of space expansion largely meaningless. Specifically, the ratio of the groove depth j to the maximum height f of the cleaning fluid tank should range from 0.4 to 0.7.

[0109] In addition, the length g of the raised edge 221 should also be limited; if the raised edge 221 is thin, its strength is poor, and it is difficult to effectively limit the cleaning liquid tank 112; if the raised edge 221 is thick, the groove 1125 needs to be enlarged, and the cleaning liquid tank will sacrifice some capacity. Therefore, the length g of the raised edge 221 is limited to 7-10mm along the length direction of the floor brush.

[0110] In specific application scenarios, in order to ensure that the cleaning fluid supply component can spray enough area, the capacity of the cleaning fluid tank 112 is usually set to 0.35-0.6L. Since the cleaning fluid tank 112 has a shell, its volume (the space required) must be greater than its capacity. In this application, the ratio of the capacity of the cleaning fluid tank to the volume of the cleaning fluid tank is limited to not less than 0.35. In this way, when the cleaning fluid tank capacity is preset, the cleaning fluid tank can be limited to not occupy too much space, so as to improve the overall compactness of the working part 11.

[0111] As an embodiment of this application, in order to make full use of the installation space on the brush body 111, the maximum length d of the cleaning fluid tank is basically the same as the maximum length a of the working part. It can be understood that, along the length direction of the brush, the distance between the two sides of the cleaning fluid tank 112 is basically equal to the distance between the two sides of the brush body 111; this allows the length of the cleaning fluid tank 112 to be designed to be as large as possible, which facilitates the adjustment of the height and width of the cleaning fluid tank 112, and thus facilitates the design of the installation position of the components on the working part 11.

[0112] As one embodiment of this application, if the width of the upper cover 1112 is too small, the beneficial effects of cleaning and disassembling the roller brush will be difficult to fully realize. Therefore, it is preferable that the ratio of the maximum width e of the cleaning fluid tank to the maximum width b of the working part is in the range of 0.5-0.7; by limiting the maximum width of the cleaning fluid tank 112, sufficient installation space is provided for the upper cover 1112, thereby making the installation of the upper cover 1112 more meaningful.

[0113] Furthermore, the rear end of the cleaning fluid tank 112 is at least partially configured as the rear end of the working part 11, that is, the cleaning fluid tank 112 is positioned as far back as possible to avoid giving way to components (such as the upper cover) located at the front of the floor brush body 111.

[0114] As an embodiment of this application, in order to ensure that the working part 11 can smoothly extend into the bed bottom area, the top of the working part 11 should not have any protruding parts 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 basically horizontal, and the two top surfaces should be basically flat to avoid step surfaces.

[0115] During the cleaning process, the working part 11 is prone to collision with obstacles on both sides along its length. To reduce the impact of collisions, the upper cover 1112 and the cleaning liquid tank 112 located on the upper part of the working part 11 are equipped with rounded corners or chamfers on both sides along the length of the floor brush.

[0116] It is worth noting that the maximum height, maximum width and maximum length of the cleaning fluid tank mentioned above refer to the height, width and length of the cleaning fluid tank body, and do not include protruding parts such as the first liquid inlet 1122 and the positioning block 1123.

[0117] Reference Figure 14 and Figure 15 This application specifies that the projection of the working part 11 along its height direction is basically rectangular, and the maximum length 'a' of the working part 11 is no greater than 270mm. Compared with other shapes, the rectangular working part, viewed from above, has a larger cleaning range and occupies less space during a single push-pull operation, while also facilitating the installation of the connecting part 12 and the cleaning fluid tank 112. By limiting its maximum length, the efficiency of the working part 11 in cleaning corner positions is improved. However, if the maximum length of the working part 11 is too small, its cleaning efficiency in open areas is low. Considering all factors, the maximum length of the working part is preferably 250-270mm.

[0118] As an embodiment of this application, in order to match the basic shape of the working part 11, this application limits the projection of the cleaning liquid tank along its height direction to be basically rectangular.

[0119] Reference Figure 17It should be noted that, because the cleaning fluid tank needs to be constructed with necessary limiting structures and / or make way for other components (such as the connecting part 12) during installation, the cleaning fluid tank in the top view cannot be a regular rectangle. Here, "basically rectangular" means that both pairs of opposite sides have parts that can achieve a basically parallel shape; in addition, the aforementioned projection of the working part along the height direction is basically rectangular, which should also be understood in the same way.

[0120] like Figure 1 As shown, in one embodiment of this application, the floor brush 1 also includes a connecting part 12 fixedly integrated with the working part 11. The floor brush 1 has a front part and a rear part, and in this embodiment, the connecting part 12 is disposed at the rear part of the working part 11.

[0121] The working section 11 not only serves as the upstream component for suctioning waste, but also needs to work with the connecting section 12 to support components such as the main body and handle, while also serving to install the cleaning fluid tank 112; therefore, the maximum width of the working section 11 needs to be further limited. Specifically, the ratio of the maximum width b to the maximum length a of the working section is in the range of 0.5-0.7; based on this, while satisfying the stable support function and the mounting carrier function of the working section, the working section can be made as small as possible.

[0122] Furthermore, to comprehensively limit the dimensions of the working section 11, the ratio of the cleaning liquid tank volume to the working section volume in this application ranges from 0.3 to 0.6. This allows for a constraint on the height of the working section 11 while determining its length and width, enabling the floor brush 1 to easily reach under beds, sofas, and other areas with limited height for cleaning. Furthermore, the ratio of the maximum height c to the maximum length a of the working section is limited to a range of 0.25 to 0.55, simultaneously satisfying the cleaning performance, convenience, and aesthetics of the working section.

[0123] The cleaning equipment mentioned in this application may be a vacuum cleaner, floor scrubber, sweeper, etc.; see reference Figure 18 and Figure 19 This includes the floor brush in any of the above embodiments.

[0124] As an embodiment of this application, the cleaning device also includes a body 5, which includes a rod-shaped rod 51; the lower part of the rod 51 has a floor brush connecting end 511 pivotally connected to the connecting part 12, and the upper part of the rod 51 has a handle end 512 for easy handholding by the user.

[0125] A handheld vacuum cleaner 6 and a dustbin 7 are detachably mounted separately on the front side of the main body 5, with the handheld vacuum cleaner 6 positioned above the dustbin 7. The main body 5 is equipped with a main body channel 50 that connects the floor brush channel 23 and the dustbin 7. The handheld vacuum cleaner 6 is any type of cordless handheld vacuum cleaner (handheld vacuum) in the prior art, which includes a dustbin assembly 61 and a power assembly 62.

[0126] When the above-mentioned cleaning equipment is in use, the handheld vacuum cleaner 6 and the sludge tank 7 are in sealed fluid communication, and the sludge tank 7 and the body channel 50 are in sealed fluid communication; the power unit 62 provides suction to clean up the garbage, and the fluid passes through the suction port 211, the floor brush channel 23, the body channel 50, the sludge tank 7 and the dust can assembly 61 in sequence, and is finally discharged from the exhaust port of the power unit 62.

[0127] The fluid in this application can be a clean airflow or an airflow carrying garbage; the garbage is at least one of dust, solid garbage (such as cigarette butts, paper scraps, rice grains, etc.), and sewage (such as orange juice, dirty water, clean water, egg liquid, etc.).

[0128] Specifically, when the fluid flows in the sludge storage tank 7 and the dust collection assembly 61, the mixture of gas, dust and / or liquid is separated in the first stage by the sludge storage tank 7; the dust and / or liquid are stored in the sludge storage tank 7, and the fluid after the first stage of separation flows from the sludge storage tank 7 into the dust collection assembly 61 for the second stage of dust-gas separation, and the separated clean air is discharged from the power assembly 62.

[0129] Of course, when cleaning up trash in a smaller space, users can detach the handheld vacuum cleaner 6 and use it directly, making the use of the cleaning equipment more versatile. As is well known to those skilled in the art, under the suction of the power component 62, fluid enters the dustbin assembly 61 from the air inlet 610 of the handheld vacuum cleaner for dust and air separation, and the separated clean air is discharged from the power component 62.

[0130] As an embodiment of this application, the body 5 is equipped with a first locking structure 92 for independently locking / unlocking the handheld vacuum cleaner 6 and a second locking structure 91 for independently locking / unlocking the sludge tank 7, so that both the handheld vacuum cleaner 6 and the sludge tank 7 can be detached separately; wherein, the first locking structure 92 and the second locking structure 91 can adopt locking structures, snap-fit ​​structures, etc., which are well known to those skilled in the art, and are not further limited in this application.

[0131] In order to ensure both fluid sealing and locking stability between the handheld vacuum cleaner 6 and the sludge tank 7, a fixed seat 8 is provided on the body 5, protruding forward and outward. The fixed seat 8 has a through hole 81, and the handheld vacuum cleaner 6 and the sludge tank 7 are respectively connected to the top and bottom of the through hole 81 in a sealed and fluid-communicating manner. The fluid after the first stage of separation enters the air inlet 610 of the handheld vacuum cleaner through the through hole 81.

[0132] like Figure 20 As shown, the body 5 is further provided with a sludge storage tank support 93, which supports the sludge storage tank 7 from the bottom or side, so that the sludge storage tank 7 can be more stably connected to the body.

[0133] By setting an outwardly protruding fixed seat 8 on the body 5, the center of gravity and most of the weight of the handheld vacuum cleaner 6 are supported on the fixed seat rather than on the body. Only a locking structure is set on the body. The fixed seat and the locking structure work together to achieve a stable fixation. Similarly, the sludge tank support, fixed seat and locking structure set on the body 5 can also solve the problem of the body having to contact the sludge tank with a large area.

[0134] This solution minimizes the required support area for the machine body, allowing the rod to be constructed as a slender rod, thereby reducing the overall weight of the machine body. Compared to existing technologies, the overall weight of the machine body can be reduced by more than 70%, and the overall appearance of the machine is more concise and clean.

[0135] Furthermore, the cross-sectional area of ​​the slender stick-shaped body remains essentially unchanged. Understandably, to facilitate the installation of necessary accessories such as locking mechanisms, its cross-sectional area will inevitably change somewhat; here, "no significant change" means that the cross-sectional area of ​​most of the stick-shaped body along its length remains largely unchanged. The aforementioned cross-sectional area of ​​the stick-shaped body will have a minimum and a maximum value. Even the maximum cross-sectional area should be less than the average cross-sectional area of ​​the fixed base, the average cross-sectional area of ​​the handheld vacuum cleaner, and the average cross-sectional area of ​​the sludge bin, preferably less than half of any of these three, to ensure the stick-shaped body's portability.

[0136] Furthermore, the ratio of the width of the pole 51 in the front-to-back direction to the length of the body ranges from 0.02 to 0.06; preferably, the width of the pole 51 in the front-to-back direction is between 43mm and 49mm, and the length of the body 5 is between 1000mm and 1200mm. These settings allow for a lighter overall weight, making it easier for users to hold and use, and also optimize the overall size and weight of the cleaning equipment.

[0137] In one embodiment of this application, the fixing seat 8 is basically annular, and the ratio of its maximum forward protrusion length to the width of the rod 51 along the front-to-back direction ranges from 1.8 to 3. This design minimizes the overall width of the fixing seat and the rod while ensuring performance, facilitating control of the rod to allow the floor brush to extend deeply into the bed. Along the length of the machine body, the ratio of the projected area of ​​the fixing seat to the projected area of ​​the rod ranges from 6.5 to 9; where the projected area refers to the area enclosed by the outer edges of the cross-section. Specifically, the preferred projected area of ​​the fixing seat is 55-80 cm². 2 .

[0138] In a preferred embodiment, when the second locking structure 91 unlocks the waste storage box 7, one end of the waste storage box support 93 can automatically move away from the machine body, thereby causing the waste storage box 7 to swing out at a certain angle, so that the user can easily take out the waste storage box 7.

[0139] Specifically, the second locking structure 91 is pivotally connected to the body 5, and its end away from the pivot point has a plate-shaped or block-shaped plug. An elastic element is provided between the second locking structure 91 and the body 5, which can spring the second locking structure 91 relative to the body 5, causing the plug to automatically move away from the body. The waste collection tank 7 has a socket 70 that can mate with the plug. When the plug rotates, the waste collection tank 7 can move in conjunction with the plug through the socket 70. Of course, changing the positions of the plug and socket can also achieve the effect of the waste collection tank 7 automatically swinging out; this detailed solution will not be elaborated upon in this application.

[0140] Furthermore, when the waste tank 7 contains liquid, if the automatic swing angle is too large, the liquid may splash or even overflow. Therefore, the automatic swing angle of the waste tank 7 relative to the machine body 5 is limited to no more than 45°. Specifically, the maximum rotation amplitude of the second locking structure 91 can be limited by installing a limiting plate on the machine body 5. In addition, to avoid the automatic swing process being too rapid, which would cause violent shaking of the liquid in the waste tank 7, this embodiment installs a rotation damper at the pivot point of the second locking structure 91. This rotation damper can be any of the existing technologies, and this application does not limit it.

[0141] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
