[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] This application provides a cleaning brush that can be installed in a cleaning device. The cleaning brush not only cleans the floor but also automatically cuts off hair tangled in its bristles, preventing interruptions to the cleaning device's operation due to excessive hair buildup.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a cleaning brush provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shown is an exploded view of a cleaning brush. The cleaning brush 000 may include: a brush body 100, a cutting component 200, and a drive component 300.

[0051] The brush body 100 in the cleaning brush 000 may have a support cavity K and a strip groove O communicating with the support cavity K. For example, the length direction of the strip groove O may be parallel to the length direction of the brush body 100.

[0052] The cutting component 200 in the cleaning brush 000 may include a first blade 201 and a second blade 202 stacked together. The first blade 201 is fixedly connected to the brush body 100 at the strip groove O, and the second blade 202 is slidably connected to the brush body 100 at the strip groove O. A portion of the first blade 201 and a portion of the second blade 202 can extend from the strip groove O of the brush body 100 to the outside of the bearing cavity K of the brush body 100. In this way, hair wrapped around the brush body 100 can contact the first blade 201 and / or the second blade 202 in the cutting component 200. Here, both the first blade 201 and the second blade 202 can be elongated blades, and the length direction of both the first blade 201 and the second blade can be parallel to the length direction of the brush body 100. When the second blade 202 in the cutting assembly 200 slides along the length of the brush body 100 at the strip groove, the second blade 202 can slide relative to the first blade 201. In this way, through the relative sliding of the first blade 201 and the second blade 202 in the cutting assembly 200, the cutting assembly 200 can cut the hair wrapped around the brush body 100.

[0053] The drive assembly 300 in the cleaning brush 000 can be located within the bearing cavity K of the brush body 100 and can be connected to both the brush body 100 and the cutting assembly 200. The drive assembly 300 can be configured to drive the second blade 202 to reciprocate relative to the first blade 201 along the length of the groove O within the strip groove O of the brush body 100 during rotation of the brush body 100 around its central axis L1. For example, the drive assembly 300 can be configured to drive the second blade 202 to reciprocate relative to the first blade 201 along the length of the groove O within the strip groove O of the brush body 100 during rotation of the brush body 100 around its central axis L1 in a first rotation direction. Here, the first rotation direction can be clockwise or counterclockwise.

[0054] In this embodiment, when the cleaning device performs cleaning operations, it can control the brush body 100 to continuously rotate around a first rotation direction to clean the floor. During this process, the second blade 202 in the cutting assembly 200 can reciprocate relative to the first blade 201 along the length of the brush body 100, allowing the cutting assembly 200 to better cut the hair wrapped around the brush body 100. The cut hair can then fall off the brush body 100, allowing the cleaning device to clean it. This not only avoids the problem of the cleaning brush 000 jamming due to excessive hair wrapped around it, thus preventing the motor in the cleaning device from stalling, but also eliminates the need for the user to manually clean the hair wrapped around the cleaning brush 000. This effectively improves the service life of the cleaning device integrating this cleaning brush 000 and enhances its cleaning effect.

[0055] In summary, this application provides a cleaning brush, which may include a brush body, a cutting component, and a driving component. When the cleaning device performs cleaning operations, it can control the brush body to continuously rotate around a first rotation direction to clean the floor. During this process, the second blade in the cutting component can reciprocate relative to the first blade along the length of the brush body, allowing the cutting component to better cut the hair wrapped around the brush body. The cut hair can then be removed from the brush body, allowing the cleaning device to clean it. This not only avoids the problem of the cleaning brush jamming due to excessive hair wrapped around it, causing the motor in the cleaning device to stall, but also eliminates the need for the user to manually clean the hair wrapped around the brush, effectively improving the service life of the cleaning device integrating this cleaning brush and enhancing its cleaning effect.

[0056] Optional, please refer to Figure 3 , Figure 3This is an exploded view of another cleaning brush provided in this application embodiment. The brush body 100 may include a first brush body portion 101 and a second brush body portion 102. The first brush body portion 101 and the second brush body portion 102 in the brush body 100 can form a supporting cavity K, and the first brush body portion 101 and the second brush body portion 102 can be arranged opposite each other in a direction perpendicular to the length of the brush body 100. The strip groove O of the brush body 100 can be located between the first brush body portion 101 and the second brush body portion 102, and the extension direction of the strip groove O is parallel to the length direction of the brush body 100. It should be noted that the brush body 100 may have two strip grooves O, and these two strip grooves O may be symmetrically distributed on both sides of the brush body 100 at a distance of 180°. It should also be noted that there may be two sets of cutting components 200, and these two sets of cutting components 200 may be symmetrically arranged at the two strip grooves O of the brush body 100 at a distance of 180°. In this case, when the cleaning brush 000 has two sets of cutting components 200, these two sets of cutting components 200 can simultaneously cut the hair wrapped around the brush body 100, thereby effectively increasing the probability of cutting the hair and allowing the hair to quickly fall off the brush body 100.

[0057] In the embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 4 This is a partial structural diagram of a cleaning brush provided in an embodiment of this application. Figure 5 This is an exploded view of another cleaning brush provided in the embodiments of this application. Figure 6 This is an exploded view of another cleaning brush provided in the embodiments of this application. The drive assembly 300 in the cleaning brush 000 may include a gear drive component and a drive rod 303. Here, the gear drive component can be rotatably connected to the brush body 100 within the bearing cavity K of the brush body 100, one end of the drive rod 303 can be rotatably connected to the gear drive component, and the other end of the drive rod 303 can be connected to the second blade 202.

[0058] During the rotation of the brush body 100, the brush body 100 can drive the second blade 202 to reciprocate relative to the first blade 201 through the gear drive component and drive rod 303.

[0059] For example, the gear drive component in the drive assembly 300 may include a drive unit 301 and a transmission wheel 302. The drive unit 301 is rotatably connected to the brush body 100 within the bearing cavity K of the brush body 100; the transmission wheel 302 is driveably connected to the drive unit 301 and rotatably connected to the brush body 100 within the bearing cavity K of the brush body 100, and the transmission wheel 302 may have an eccentric member 302a, the axis of which may not coincide with the axis of the transmission wheel 302 (i.e., the central axis of the transmission wheel, which is also the axis of rotation of the transmission wheel relative to the brush body). One end of the drive rod 303 is rotatably connected to the eccentric member 302a in the transmission wheel 302, and the other end of the drive rod 303 is connected to the second blade 202.

[0060] During the rotation of the brush body 100, the brush body 100 can drive the transmission wheel 302 to rotate around its axis via the drive unit 301 in the drive assembly 300, thereby driving the second blade 202 to reciprocate relative to the first blade 201 via the drive rod 303. Thus, during the cleaning process, as the cleaning brush 100 rotates, the brush body 100 can simultaneously drive the transmission wheel 302 to rotate around its own axis via the drive unit 301, while the drive rod 303, connected to the eccentric member 302a on the transmission wheel 302, can drive the second blade 202 to reciprocate relative to the first blade 201, achieving hair cutting. For example, the eccentric member 302a can be an eccentric rod fixed to the transmission wheel 302, and one end of the drive rod 303 can be sleeved on the eccentric rod and rotatably connected to it.

[0061] Optional, such as Figure 3 and Figure 4 As shown, the drive unit 301 in the drive assembly 300 may include a fixed rod 301a and an intermediate transmission mechanism. Here, both the fixed rod 301a and the intermediate transmission mechanism are rotatably connected to the brush body 100 within the bearing cavity K of the brush body 100. The axis L2 of the fixed rod 301a may coincide with the axis L1 of the brush body 100, and one end of the fixed rod 301a may be connected to the intermediate transmission mechanism. The intermediate transmission mechanism may also be connected to the transmission wheel 302, and the transmission wheel 302 may be distributed on the side of the intermediate transmission mechanism opposite to the fixed rod 301a.

[0062] During the rotation of the brush body 100 around the fixed rod 301a, the intermediate transmission mechanism can drive the transmission wheel 302 to rotate around the axis of the transmission wheel 302.

[0063] For example, such as Figure 3 and Figure 4As shown, the intermediate transmission mechanism may include a transmission rod 301b. The axis L3 of the transmission rod 301b may intersect with the axis L2 of the fixed rod 301a. One end of the fixed rod 301a may be connected to the outer side of the transmission rod 301b, and the outer side of the transmission rod 301b may also be connected to the transmission wheel 302, which may be distributed on the side of the transmission rod 301b away from the fixed rod 301a.

[0064] During the rotation of the brush body 100 around the fixed rod 301a, the transmission rod 301b rotates around its axis under the transmission action of the fixed rod 301a. In this case, during the rotation of the brush body 100 around the fixed rod 301a, the transmission rod 301b, through its transmission connection with the fixed rod 301a, can rotate around its own axis, thereby driving the transmission wheel 302 to rotate, so that the drive rod 303 can drive the second blade 202 to reciprocate relative to the first blade 201.

[0065] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the end of the fixed rod 301a facing the transmission rod 301b in the drive unit 301 may have a plurality of first external teeth A1 distributed around the axis L2 of the fixed rod 301a, and the outer surface of the transmission rod 301b may have a plurality of second external teeth A2 distributed around the axis L3 of the transmission rod 301b. At least some of the first external teeth A1 on the fixed rod 301a can mesh with at least some of the second external teeth A2 on the transmission rod 301b. Thus, through the meshing of the plurality of second external teeth A2 with the plurality of first external teeth A1 in the fixed rod 301a, the transmission rod 301b can rotate around its own axis as the brush body 100 rotates around the fixed rod 301a, thereby driving the transmission wheel 302 to rotate.

[0066] In this application, as Figure 3 and Figure 4 As shown, the outer edge of the transmission wheel 302 may have multiple third external teeth B1 distributed around its axis L4, and the outer surface of the transmission rod 301b may also have guide teeth B2 extending in a spiral shape. At least some of the third external teeth B1 on the transmission wheel 302 can mesh with the spiral guide teeth B2 on the transmission rod 301b. Thus, during the rotation of the transmission rod 301b around its own axis, the meshing of the multiple third external teeth B1 and the spiral guide teeth B2 drives the transmission wheel 302 to rotate around its own axis.

[0067] For example, the transmission wheel 302 in the drive assembly 300 can be a worm gear, and the transmission rod 301b can be a worm, the end of which can have multiple second external teeth A2. Here, the multiple first external teeth A1 distributed on the end of the fixed rod 301a and the multiple second external teeth A2 distributed on the outer surface of the transmission rod 301b can all be bevel teeth.

[0068] In this application, as Figure 5 As shown, the cleaning brush 000 may further include a fixing part 400 and a transmission part 500 respectively connected to both ends of the brush body 100. The fixing part 400 can be fixedly connected to one end of the fixing rod 301a away from the transmission rod 301b. The transmission part 500 can be used for connection to the drive end in the cleaning device, and the fixing part 400 can be used for connection to the fixing end in the cleaning device. Here, the fixing part 400 in the cleaning brush 000 can be rotatably connected to the brush body 100, and the brush body 100 can rotate around the fixing part 400. For example, the drive end in the cleaning device may include a rotation drive motor (not shown in the figure). Thus, the rotation drive motor can drive the brush body 100 to rotate by driving the transmission part 500 in the cleaning brush. Furthermore, since the fixing part 400 in the cleaning brush 000 is connected to the fixing rod 301a in the drive assembly 300 and the fixing end in the cleaning device respectively, the fixing rod 301a in the drive assembly 300 is stationary within the bearing cavity K in the brush body 100. Therefore, during the process of the brush body 100 rotating around the fixed rod 301a and the transmission rod 301b rotating around its own axis under the transmission action of the fixed rod 301a, the fixed rod 301a will not rotate with the brush body 100.

[0069] Optional, please refer to Figure 7 , Figure 7This is a schematic diagram of a partial structure of another cleaning brush provided in an embodiment of this application. The included angle α between the axis L2 of the fixed rod 301a and the axis L3 of the transmission rod 301b in the drive unit 301 can be an acute angle. In this case, by setting the included angle between the axis L3 of the transmission rod 301b and the axis L2 of the fixed rod 301a to an acute angle, the transmission rod 301b can be tilted, thus effectively reducing the inner diameter of the brush body 100 and facilitating the miniaturization design of the cleaning device. For example, the included angle formed between the transmission rod 301b and the fixed rod 301a can be greater than 0 degrees and less than or equal to 70 degrees. It should be noted that in other possible implementations, the axis L2 of the fixed rod 301a and the axis L3 of the transmission rod 301b in the drive unit 301 can be perpendicular to each other. In this application, the inner wall of the bearing cavity K of the brush body 100 may have two support platforms K1 arranged opposite to each other along the axis of the transmission rod 301b. The support platform K1 may have a rotating support hole K11, and the end of the transmission rod 301b may be located in the rotating support hole K11 and may be rotatably connected to the rotating support hole K11.

[0070] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the cleaning brush 000 may further include a sliding portion 600 rotatably connected to one end of the drive rod 303 opposite to the transmission wheel 302. This sliding portion 600 is slidably connected to the brush body 100 within the bearing cavity K of the brush body 100, and can be fixedly connected to the second blade 202. In this case, by providing the sliding portion 600, the drive rod 303 and the second blade 202 can be switched, facilitating the installation of the second blade 202 and the drive rod 303.

[0071] Optional, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 8 , Figure 8This is an exploded view of a partial structure of a cleaning brush provided in an embodiment of this application. The sliding part 600 may include: a sliding part body 601, a limiting member 602 fixedly connected to the sliding part body 601, and a first support column 603 and a second support column 604 located between the sliding part body 601 and the limiting member 602. The sliding part body 601 may be disposed opposite to the limiting member 602. One end of the drive rod 303 away from the transmission wheel 302 can be rotatably connected to the sliding part body 601 through the first support column 603. The second blade 202 may have a first fixing hole a1 corresponding to the second support column 604, and the second blade 202 can be sleeved on the second support column 604 through the first fixing hole a1. In this configuration, after the drive rod 303 is rotatably connected to the sliding part body 601 via the first support column 603, and the second blade 202 is connected to the sliding part body 601 via the first fixing hole a1 and the cooperation of the second support column 604, the connection between the limiting member 602 and the sliding part body 601 enables the second blade 202 to be limited along the axial direction of the second support column 604, preventing it from falling off the sliding part body 601. It also enables the drive rod 303 to be limited along the axial direction of the first support column 603, preventing it from falling off the sliding part body 601. This increases the stability of the connection between the drive rod 303, the second blade 202, and the sliding part 600.

[0072] In this application, as Figure 8As shown, the first support column 603 can be fixedly connected to the end of the drive rod 303 opposite to the transmission wheel 302. The sliding part body 601 can have a first rotating hole b1 rotatably connected to the first support column 603, and / or, the limiting member 602 can have a second rotating hole b2 rotatably connected to the first support column 603. It should be noted that when the sliding part body 601 has the first rotating hole b1 and the limiting member 602 has the second rotating hole b2, the first rotating hole b1 and the second rotating hole b2 are arranged opposite to each other and communicate with each other. A part of the first support column 603 can be located in the first rotating hole b1, and another part of the first support column 603 can be located in the second rotating hole b2. In other possible implementations, the first support column 603 can be fixedly connected to the sliding part body 601 and / or the limiting member 602. The end of the drive rod 303 facing away from the transmission wheel 302 can have a rotatable connection hole (not shown in the figure). The drive rod 303 can be sleeved on the first support column 603 through the rotatable connection hole and rotatably connected to the first support column 603. In this application, the second support column 604 can be fixed on the sliding part body 601. The first fixing hole a1 in the second blade 202 can be sleeved on the second support column 604. The limiting member 602 can have a positioning hole c1. The limiting member 602 can be installed and positioned by cooperating with the second support column 604 through the positioning hole c1. For example, the corner of the sliding part body 601 may have a threaded hole c2, and the corner of the limiting member 602 may have a through hole c3 communicating with the threaded hole c2. The sliding part 600 may also include a fastener 605, one end of which may pass through the through hole c3 and be fastened to the threaded hole c2 to achieve a fixed connection between the limiting member 602 and the sliding part body 601, thereby limiting the drive rod 303 and the second blade 202. For example, the fastener 605 may be a fastening screw.

[0073] In the embodiments of this application, please refer to Figure 9 , Figure 9This is an exploded view of a partial structure of another cleaning brush provided in this application embodiment. The bearing cavity K in the brush body 100 may have a third support post 103. The portion of the first blade 201 in the cutting assembly 200 extending into the bearing cavity K may have a second fixing hole S1, and the portion of the second blade 202 extending into the bearing cavity K may have a strip-shaped hole S2. The first blade 202 in the cutting assembly 200 can be fixed to the third support post 103 in the brush body 100 through the second fixing hole S1. Thus, through the fixed engagement of the second fixing hole S1 of the first blade 201 with the third support post 103 in the brush body 100, the first blade 201 in the cutting assembly 200 can be fixedly connected to the brush body 100. The second blade 202 in the cutting assembly 200 can be sleeved on the third support post 103 in the brush body 100 through the strip-shaped hole S2, and the second blade 202 can slide relative to the third support post 103 in the brush body 100 through the strip-shaped hole S2. Thus, through the sliding engagement between the strip-shaped hole S2 in the first blade 202 and the third support post 103 in the brush body 100, the second blade 202 in the cutting assembly 200 can be slidably connected to the brush body 100. It should be noted that the strip-shaped hole S2 can limit the movement distance of the second blade 202 relative to the first blade 201.

[0074] Optional, such as Figure 8 As shown, the portion of the first blade 201 in the cutting assembly 200 extending out of the bearing cavity K in the brush body 100 may have multiple first cutting teeth 201a, and the portion of the second blade 202 in the cutting assembly 200 extending out of the bearing cavity K in the brush body 100 may have multiple second cutting teeth 202a. Here, the multiple first cutting teeth 201a in the first blade 201 may be arranged in an array along the length direction of the brush body 100, and these first cutting teeth 201a may all extend from the strip groove O of the brush body 100; the multiple second cutting teeth 202a in the second blade 202 may also be arranged in an array along the length direction of the brush body 100, and these second cutting teeth 201b may also all extend from the strip groove O of the brush body 100.

[0075] In this application, the number of teeth of the plurality of second cutting comb teeth 202a in the second blade 202 can be less than the number of teeth of the plurality of first cutting teeth in the first blade 201. That is, the length of the second blade 202 in the cutting assembly 200 can be less than the length of the first blade 201. This ensures that the second blade 202 in the cutting assembly 200 will not extend beyond the end of the first blade 201 during the sliding process relative to the first blade 201 along the length direction of the brush body 100.

[0076] Optional, such as Figure 8As shown, the first brush body portion 101 of the brush body 100 may have a plurality of first guide teeth 101a corresponding one-to-one with a plurality of first cutting comb teeth 201a on the side facing the strip groove O of the brush body 100, and the second brush body portion 102 of the brush body 100 may have a plurality of second guide teeth (not shown in the figure) corresponding one-to-one with a plurality of second cutting comb teeth 202a on the side facing the strip groove O of the brush body 100. Each first cutting comb tooth 201a in the first blade 201 may be distributed between the corresponding first guide teeth 101a and second guide teeth, and each second cutting comb tooth 202a in the second blade 202 may also be distributed between the corresponding first guide teeth 101a and second guide teeth.

[0077] It should be noted that when the cleaning brush 000 is performing cleaning work, the multiple first guide combs 101a in the first brush body 101 and the multiple second guide combs 102 in the second brush body 102 allow the hair wrapped around the brush body 100 to be distributed between two adjacent first guide combs 101a and between two adjacent first guide combs 101a, so that the hair can be distributed between two adjacent first cutting combs 201a in the first blade 201. In this way, when the second blade 202 slides relative to the first blade 201, the hair distributed between the two adjacent first cutting combs 201a can be cut by the combined action of the first cutting combs 201a in the first blade 201 and the second cutting combs 202a in the second blade 202.

[0078] Optional, such as Figure 9 As shown, the brush body 100 in the cleaning brush 000 may further include a limiting clamping strip 104 located between the first brush body portion 101 and the second brush body portion 102. This limiting clamping strip 104 may be located on the side of the first blade 201 in the cutting assembly 200 that faces away from the second blade 202. It should be noted that the limiting clamping strip 104, the first blade 201, and the second blade 201 may all be distributed between the first guide comb teeth 101a and the second guide comb teeth. Here, the limiting clamping strip 104 can limit the second blade in the cutting assembly 200 in the length direction perpendicular to the brush body 100, preventing the second blade 202 in the cutting assembly 200 from moving in the length direction perpendicular to the brush body 100, further ensuring the stability of the second blade 202 sliding relative to the first blade 201 in the length direction of the brush body 100.

[0079] In summary, this application provides a cleaning brush, which may include a brush body, a cutting component, and a driving component. When the cleaning device performs cleaning operations, it can control the brush body to continuously rotate around a first rotation direction to clean the floor. During this process, the second blade in the cutting component can reciprocate relative to the first blade along the length of the brush body, allowing the cutting component to better cut the hair wrapped around the brush body. The cut hair can then be removed from the brush body, allowing the cleaning device to clean it. This not only avoids the problem of the cleaning brush jamming due to excessive hair wrapped around it, causing the motor in the cleaning device to stall, but also eliminates the need for the user to manually clean the hair wrapped around the brush, effectively improving the service life of the cleaning device integrating this cleaning brush and enhancing its cleaning effect.

[0080] The application also provides a cleaning device, please refer to the embodiments. Figure 10 , Figure 10 This is a schematic diagram of a cleaning device provided in an embodiment of this application. The cleaning device 00 may include: a device body 001, and a cleaning brush 000 connected to the device body 001. The cleaning brush 000 can be the cleaning brush 000 shown in the above embodiment. After the cleaning brush 000 is integrated into the cleaning device 00, the cleaning device 00 can perform cleaning work. After cleaning for a period of time, the cleaning device 00 can control the cleaning brush 000 to cut off the hair wrapped around it, thus preventing excessive hair from tangling on the cleaning brush 000. Furthermore, the cleaning brush 000 in the cleaning device 00 is freely installable and detachable. This allows the cleaning brush 000 to be installed in a cleaning device without a hair-cutting function, enabling the cleaning device 00 to simultaneously have both cleaning and hair-cutting functions. Therefore, a cleaning device without a hair-cutting function can simultaneously have both cleaning and hair-cutting functions simply by replacing the cleaning brush 000, which reduces the overall manufacturing cost of the cleaning device 00.
