Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and more particularly to a floor brush and cleaning device. Background Technology

[0002] Cleaning equipment may include a main unit and a floor brush. The floor brush is equipped with a roller brush, which rotates and uses the negative pressure suction provided by the main unit to suck up dirt from the floor. Since the floor usually contains dirt such as hair, especially when the hair is long, the hair can easily get tangled on the roller brush, which will increase the load on the roller brush motor, thereby increasing the current of the roller brush motor, which will cause the temperature of the roller brush motor to rise, affecting the service life of the roller brush motor.

[0003] In related technologies, in order to protect the roller brush motor, the roller brush motor is equipped with an overcurrent shutdown function. That is, when the current of the roller brush motor is too high due to hair entanglement, the roller brush motor will automatically stop. Although this protects the roller brush motor, it will interrupt the user's vacuuming operation, thereby reducing the cleaning efficiency of the cleaning equipment. In addition, the hair on the roller brush needs to be cleaned manually by the user, which increases the user's burden. Utility Model Content

[0004] Based on this, this application provides a floor brush and a cleaning device. The floor brush has a better effect in preventing hair tangling, thereby improving the cleaning efficiency of the cleaning device and reducing the user's operating burden.

[0005] In a first aspect, this application provides a floor brush, which includes: a housing, a roller brush, and a hair cutting assembly, wherein the roller brush is rotatably disposed in the housing;

[0006] The hair cutting assembly includes a drive motor, a transmission unit, and a cutting component. The drive motor is connected to the housing, and the rotation axis of the drive motor is aligned with the axis of the roller brush. The drive motor is connected to the cutting component through the transmission unit to drive the cutting component to reciprocate along the axis of the roller brush.

[0007] The floor brush provided in this embodiment features a housing for mounting a roller brush and a hair-cutting component. The roller brush cleans the surface to be cleaned, and the cutting component cuts hair tangled on the roller brush, eliminating the need for manual hair removal. A drive motor provides power to the cutting component, causing it to move back and forth along the roller brush's axis. A transmission unit stably transmits the drive motor's power to the cutting component. By aligning the drive motor's rotation axis with the roller brush's axis, the floor brush has a smaller front-to-back dimension and a larger left-to-right dimension, thus increasing the contact area between the roller brush and the surface to be cleaned and improving cleaning efficiency. Therefore, the floor brush provided in this embodiment offers high cleaning efficiency and excellent cleaning effect.

[0008] In one possible implementation, the transmission unit includes a transmission rod extending in the same direction as the axial direction of the roller brush, a cutting element threadedly connected to the transmission rod, and a drive motor connected to the transmission rod to drive the transmission rod to rotate.

[0009] In this way, the drive motor can drive the transmission rod to rotate, and the cutting part is threadedly connected to the transmission rod. In turn, the cutting part can be driven to move back and forth along the extension direction of the transmission rod, thereby cutting the hair wrapped around the roller brush.

[0010] In one possible implementation, the cutting element includes a movable part and a cutting part connected to each other, the cutting part being positioned toward the roller brush, the drive rod having an external thread, and the movable part having an internal thread that matches the external thread, the internal thread being threadedly connected to the external thread.

[0011] Thus, when the transmission rod rotates under the drive of the drive motor, it can drive the moving part to move back and forth along the extension direction of the transmission rod, and in turn drive the cutting part connected to the moving part to move back and forth along the axis of the roller brush. The cutting part facing the roller brush can be used to cut the hair on the roller brush.

[0012] In one possible implementation, the drive rod and the drive motor are arranged along the travel direction of the floor brush, with the drive rod located between the drive motor and the roller brush.

[0013] This allows for a more reasonable layout of the floor brush, making effective use of its space. Furthermore, the transmission rod is positioned between the drive motor and the roller brush, enabling the cutting element to be placed adjacent to the roller brush, thus facilitating the cutting element's ability to cut the hair entangled on the roller brush.

[0014] In one possible implementation, the transmission unit further includes a first gear and a second gear, the first gear being coaxially connected to the drive motor, the second gear meshing with the first gear, and the transmission rod being coaxially connected to the second gear.

[0015] In this way, the driving force of the drive motor can be transmitted to the cutting part in sequence along the first gear, the second gear and the transmission rod, thereby driving the cutting part to move back and forth along the axis of the roller brush. The use of the first gear, the second gear and the transmission rod to transmit the driving force can ensure the stability of the back and forth movement of the cutting part, thereby enabling the cutting part to quickly and effectively cut the hair wrapped on the roller brush.

[0016] In one possible implementation, the transmission unit further includes two fixed sleeves, the housing has two mounting slots located at both ends of the transmission rod, the two ends of the transmission rod include a support end and a transmission end, the support end and the transmission end are respectively connected to the two mounting slots through the two fixed sleeves, and the end face of the transmission end protrudes from the fixed sleeve connected to it, and the transmission end is connected to the drive motor.

[0017] In this way, the two ends of the transmission rod can be rotatably connected to the two fixed sleeves, which in turn allows the two ends of the transmission rod to be rotatably connected to the two mounting slots, and thus allows the two ends of the transmission rod to be rotatably connected to the housing, thereby reducing the wear of the housing. The end face of the transmission end protrudes from the fixed sleeve connected to it, so that the transmission end can extend out of the fixed sleeve and connect to the drive motor, thereby allowing the drive motor to drive the transmission rod to rotate.

[0018] In one possible implementation, one of the housing and the moving part has a guide rail, and the other has a groove, which is slidably connected to the guide rail, and the extension direction of the guide rail is consistent with the axial direction of the brush.

[0019] In this way, after the slidable connection between the chute and the guide rail, the relative position of the cutting part and the transmission rod in the radial direction of the roller brush can be restricted, thereby ensuring the relative position of the cutting part and the roller brush, so that the cutting part always faces the roller brush, and the moving part always moves relative to the housing in the axial direction of the roller brush.

[0020] In one possible implementation, the housing has guide rails, and the guide rails and transmission rods are located on opposite sides of the moving part.

[0021] This allows the moving part to connect to both the guide rail and the drive rod simultaneously, and also makes the structure of the floor brush more compact.

[0022] In one possible implementation, the transmission unit further includes a third gear that meshes between the first gear and the second gear.

[0023] In this way, the driving force of the drive motor can be transmitted to the cutting part in sequence through the first gear, the third gear, the second gear and the transmission rod, thereby driving the cutting part to move back and forth along the axis of the roller brush.

[0024] In one possible implementation, the cutting section has at least one cutting tooth, the at least one cutting tooth including a first cutting tooth having a pointed angle projecting toward the roller brush.

[0025] In this way, the first cutting tooth protruding towards the roller brush can quickly cut off the hair wrapped around the roller brush.

[0026] In one possible implementation, at least one cutting tooth further includes a plurality of second cutting teeth, which are arranged radially along the roller brush and located on opposite sides of the roller brush in the radial direction.

[0027] In this way, the first and second cutting teeth can work together to accurately and quickly cut the hair wrapped around the roller brush, thereby improving the cutting effect of the cutting section.

[0028] Secondly, this application provides a cleaning device, including a device host and the floor brush provided in the first aspect, wherein the floor brush is connected to the device host.

Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0056] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0058] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0059] Because the ground is often covered with hair and other dirt, especially long hair, it easily gets tangled on the roller brush. This increases the load on the roller brush motor, leading to increased current and consequently higher motor temperature, thus affecting its lifespan. Related technologies incorporate an overcurrent shutdown function to protect the roller brush motor. This means that when the current becomes too high due to hair entanglement, the roller brush motor automatically shuts down. While this protects the motor, it interrupts the user's vacuuming operation, reducing the cleaning efficiency of the equipment. Furthermore, the hair on the roller brush needs to be manually removed, increasing the user's workload.

[0060] In view of this, embodiments of this application provide a floor brush and a cleaning device. The floor brush automatically cuts the hair wrapped around the roller brush by setting a hair cutting component, thereby avoiding the cleaning device from stopping, thus improving the cleaning efficiency of the cleaning device and reducing the user's operating burden.

[0061] The specific implementation of the cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings.

[0062] Reference Figure 1 As shown in the illustration, this application provides a cleaning device, which includes a main unit and a floor brush connected to the main unit. The floor brush can contact the surface to be cleaned, and the main unit can provide suction to the floor brush to collect dirt from the surface.

[0063] For example, the cleaning equipment can be a vacuum cleaner, or it can be a floor scrubber.

[0064] Reference Figures 1 to 7 As shown, based on the above embodiments, this application embodiment also provides a floor brush, which includes a housing 100, a roller brush 200 and a hair cutting component 300, with the roller brush 200 rotatably disposed on the housing 100.

[0065] The hair cutting assembly 300 includes a drive motor 310, a transmission unit 320, and a cutting element 330. The drive motor 310 is connected to the housing 100, and the rotation axis of the drive motor 310 is aligned with the axis of the roller brush 200. The drive motor 310 is connected to the cutting element 330 through the transmission unit 320 to drive the cutting element 330 to reciprocate along the axis of the roller brush 200.

[0066] In this embodiment, the housing 100 is used to install the roller brush 200 and the hair cutting component 300, etc. The roller brush 200 is rotatably connected to the housing 100, so that when the floor brush walks on the surface to be cleaned, the roller brush 200 can roll and contact the surface to be cleaned, thereby lifting up the dirt on the surface to be cleaned or wiping the surface to be cleaned.

[0067] Since the roller brush 200 rotates continuously during operation, and when there is hair on the surface to be cleaned, the hair will inevitably get tangled on the roller brush 200. Therefore, the floor brush in this embodiment automatically cuts the hair tangled on the roller brush 200 by setting a hair cutting component 300, and then sucks away the cut hair by the suction force provided by the main unit of the device. In this way, the user does not need to manually clean the hair tangled on the roller brush 200, and the cleaning device will not start the shutdown protection as a result.

[0068] Specifically, the hair cutting assembly 300 may include a drive motor 310, a transmission unit 320, and a cutting element 330. The drive motor 310 can provide driving force, thereby driving the cutting element 330 to move back and forth along the axial direction of the roller brush 200, thereby causing the cutting element 330 to cut the hair wrapped around the roller brush 200. The transmission unit 320 is used to connect the drive motor 310 and the cutting element 330, thereby stably transmitting the driving force of the drive motor 310 to the cutting element 330.

[0069] The drive motor 310 can rotate forward or backward, thereby driving the cutting piece 330 to move between the two ends of the roller brush 200.

[0070] It should be noted that in this embodiment, one roller brush 200 can be disposed on the front side of the floor brush, or one roller brush 200 can be disposed on the front and rear sides of the floor brush respectively. The axial direction of the roller brush 200 is consistent with the left-right direction of the floor brush, and the rotation axis of the drive motor 310 is consistent with the axial direction of the roller brush 200. That is to say, the drive motor 310 is disposed along the left-right direction of the floor brush, and the radial dimension of the drive motor 310 is smaller and the axial dimension is larger. In this way, with the same volume, the front-back dimension of the floor brush is smaller and the left-right dimension is larger. When the left-right dimension of the floor brush is larger, the axial length of the roller brush 200 can be increased, thereby increasing the contact area between the roller brush 200 and the surface to be cleaned, thereby improving the cleaning efficiency of the floor brush.

[0071] The floor brush provided in this embodiment includes a housing 100, a roller brush 200, and a hair cutting assembly 300. The hair cutting assembly 300 may include a drive motor 310, a transmission unit 320, and a cutting element 330. The housing 100 is used to mount the roller brush 200 and the hair cutting assembly 300. The roller brush 200 is used to clean the surface to be cleaned, and the cutting element 330 is used to cut the hair wrapped around the roller brush 200, thus eliminating the need for manual hair removal by the user. The drive motor 310 provides driving force to the cutting element 330, causing it to move back and forth along the axial direction of the roller brush 200. The transmission unit 320 stably transmits the driving force of the drive motor 310 to the cutting element 330. By aligning the rotation axis of the drive motor 310 with the axial direction of the roller brush 200, the floor brush has a smaller front-to-back dimension and a larger left-to-right dimension, thereby increasing the contact area between the roller brush 200 and the surface to be cleaned and improving the cleaning efficiency of the floor brush. Therefore, the floor brush provided in this embodiment has high cleaning efficiency and good cleaning effect.

[0072] Reference Figures 7 to 10 As shown, in one possible implementation, the transmission unit 320 includes a transmission rod 321, the extension direction of which is consistent with the axial direction of the roller brush 200, the cutting member 330 is threadedly connected to the transmission rod 321, and the drive motor 310 is connected to the transmission rod 321 to drive the transmission rod 321 to rotate.

[0073] In this way, the drive motor 310 can drive the transmission rod 321 to rotate, and the cutting part 330 is threadedly connected to the transmission rod 321. Thus, the cutting part 330 can be driven to move back and forth along the extension direction of the transmission rod 321 through the transmission rod 321, thereby cutting the hair wrapped around the roller brush 200.

[0074] Reference Figures 9 to 13 As shown, in a specific implementation, the cutting component 330 includes a moving part 331 and a cutting part 332 connected to each other. The cutting part 332 is disposed toward the roller brush 200. The transmission rod 321 has an external thread 3211, and the moving part 331 has an internal thread 3311 that matches the external thread 3211. The internal thread 3311 is threadedly connected to the external thread 3211.

[0075] With this configuration, when the transmission rod 321 rotates under the drive of the drive motor 310, it can drive the moving part 331 to move back and forth along the extension direction of the transmission rod 321, thereby driving the cutting part 332 connected to the moving part 331 to move back and forth along the axial direction of the roller brush 200. The cutting part 332 facing the roller brush 200 can be used to cut the hair on the roller brush 200.

[0076] In some embodiments, the drive rod 321 and the drive motor 310 are arranged along the travel direction of the floor brush, with the drive rod 321 located between the drive motor 310 and the roller brush 200.

[0077] In other words, the transmission rod 321 and the drive motor 310 can be arranged along the front and rear direction of the floor brush, the roller brush 200 can be arranged on the front side of the floor brush, the drive motor 310 can be arranged on the rear side of the floor brush, and the transmission rod 321 can be arranged between the drive motor 310 and the roller brush 200, so that the layout of the floor brush is more reasonable and the space of the floor brush can be effectively utilized. Furthermore, the arrangement of the transmission rod 321 between the drive motor 310 and the roller brush 200 allows the cutting element 330 to be arranged adjacent to the roller brush 200, thereby facilitating the cutting element 330 to cut the hair wrapped around the roller brush 200.

[0078] Reference Figures 8 to 10 , Figure 14 , Figure 15 As shown, in one possible implementation, the transmission unit 320 further includes a first gear 322 and a second gear 323. The first gear 322 is coaxially connected to the drive motor 310, the second gear 323 meshes with the first gear 322, and the transmission rod 321 is coaxially connected to the second gear 323.

[0079] In this way, the driving force of the drive motor 310 can be transmitted to the cutting element 330 in sequence along the first gear 322, the second gear 323 and the transmission rod 321, thereby driving the cutting element 330 to move back and forth along the axial direction of the roller brush 200. The use of the first gear 322, the second gear 323 and the transmission rod 321 to transmit the driving force can ensure the stability of the back and forth movement of the cutting element 330, thereby enabling the cutting element 330 to quickly and effectively cut the hair wrapped around the roller brush 200.

[0080] Reference Figure 9 , Figure 10 As shown, in some embodiments, the transmission unit 320 further includes two fixed sleeves 324, the housing 100 has two mounting slots 110, the two mounting slots 110 are located at both ends of the transmission rod 321, the two ends of the transmission rod 321 include a support end 3212 and a transmission end 3213, the support end 3212 and the transmission end 3213 are respectively connected to the two mounting slots 110 through the two fixed sleeves 324, and the end face of the transmission end 3213 protrudes from the fixed sleeve 324 connected to it, and the transmission end 3213 is connected to the drive motor 310.

[0081] In this way, both ends of the transmission rod 321 can be rotatably connected to the two fixed sleeves 324, thereby allowing both ends of the transmission rod 321 to be rotatably connected to the two mounting slots 110, and thus allowing both ends of the transmission rod 321 to be rotatably connected to the housing 100, thereby reducing the wear of the housing 100. Furthermore, the end face of the transmission end 3213 protrudes from the fixed sleeve 324 connected to it, so that the transmission end 3213 can extend out of the fixed sleeve 324 and connect to the drive motor 310, thereby allowing the drive motor 310 to drive the transmission rod 321 to rotate.

[0082] Reference Figure 9 , Figure 11 As shown, in one possible implementation, one of the housing 100 and the moving part 331 has a guide rail 120 and the other has a groove 3312, which is slidably connected to the guide rail 120, and the extending direction of the guide rail 120 is consistent with the axial direction of the roller brush 200.

[0083] It is understandable that when the transmission rod 321 rotates, it can drive the cutting part 330 to move along the axial direction of the roller brush 200. When the transmission rod 321 rotates, it may also drive the cutting part 330 to rotate around the axial direction of the roller brush 200. This will affect the relative position of the cutting part 330 and the roller brush 200. Therefore, the housing 100 can be provided with a guide rail 120, and the moving part 331 can be provided with a sliding groove 3312. Alternatively, the housing 100 can be provided with a sliding groove 3312, and the moving part 331 can be provided with a guide rail 120. After the sliding groove 3312 and the guide rail 120 are slidably connected, the relative position of the cutting part 330 and the transmission rod 321 in the radial direction of the roller brush 200 can be restricted, thereby ensuring the relative position of the cutting part 330 and the roller brush 200. This ensures that the cutting part 332 always faces the roller brush 200, and that the moving part 331 always moves relative to the housing 100 along the axial direction of the roller brush 200.

[0084] In one possible implementation, the housing 100 has a guide rail 120, and the guide rail 120 and the transmission rod 321 are located on opposite sides of the moving part 331.

[0085] In other words, the internal thread 3311 and the slide groove 3312 can be located on the upper and lower sides of the moving part 331, and the guide rail 120 and the transmission rod 321 can be located on the upper and lower sides of the moving part 331 respectively, so that the guide rail 120 and the slide groove 3312 are connected, and the internal thread 3311 is connected to the external thread 3211.

[0086] For example, the transmission rod 321 is located on the upper side of the moving part 331, and the guide rail 120 is located on the lower side of the moving part 331. In this way, the moving part 331 can be connected to both the guide rail 120 and the transmission rod 321 at the same time, and the structure of the floor brush can be made more compact.

[0087] Reference Figures 16 to 19As shown, in one possible implementation, the transmission unit 320 further includes a third gear 325, which meshes between the first gear 322 and the second gear 323.

[0088] It can be understood that the driving force of the drive motor 310 can be transmitted to the cutting piece 330 in sequence through the first gear 322, the third gear 325, the second gear 323 and the transmission rod 321, thereby driving the cutting piece 330 to reciprocate along the axial direction of the roller brush 200.

[0089] Among them, the first gear 322, the second gear 323 and the third gear 325 can all be spur gears, or the first gear 322, the second gear 323 and the third gear 325 can all be helical gears. The embodiments of this application do not limit this.

[0090] Reference Figures 11 to 13 As shown, in one possible implementation, the cutting portion 332 has at least one blade 3321, the at least one blade 3321 including a first blade 3321a, the first blade 3321a having a sharp angle protruding toward the roller brush 200.

[0091] In other words, the first cutting tooth 3321a can be triangular. With this configuration, the first cutting tooth 3321a protruding towards the roller brush 200 can quickly cut the hair wrapped around the roller brush 200.

[0092] Reference Figures 11 to 13 As shown in some embodiments, at least one blade 3321 further includes a plurality of second blades 3321b, which are arranged radially along the roller brush 200 and located on opposite sides of the roller brush 200 in the radial direction.

[0093] In this way, the first cutting tooth 3321a and the second cutting tooth 3321b can work together to accurately and quickly cut the hair wrapped around the roller brush 200, thereby improving the cutting effect of the cutting part 332.

[0094] The second cutting tooth 3321b can be triangular, and the gap between two adjacent second cutting teeth 3321b can be triangular; alternatively, the second cutting tooth 3321b can be trapezoidal, and the gap between two adjacent second cutting teeth 3321b can also be trapezoidal.
