Description

[0001] This application is a divisional application of Chinese invention patent filed on August 23, 2021, entitled "Transmission Component, Cutting Mechanism, Roller Brush Device and Cleaning Equipment", with application number "202110971083.9". Technical Field

[0002] This invention relates to the field of cleaning tool technology, specifically to a transmission component, a cutting mechanism, a roller brush device, and a cleaning equipment. Background Technology

[0003] Vacuum cleaners and other cleaning equipment use roller brushes to remove debris from the floor. When the roller brush comes into contact with the floor or carpet, it easily gets tangled with hair and other fibrous materials. Excessive tangling of these materials can impair suction, even jamming the roller and causing the motor to stall, ultimately damaging the motor and severely impacting the vacuum cleaner's lifespan. The traditional solution is to use a hair-cutting mechanism, which consists of a driver and a cutting element. The driver moves the cutting element to cut the hair on the roller brush. However, this method of driver operation is limited, and adding a driver increases costs. Summary of the Invention

[0004] Therefore, the present invention aims to solve the problem that the driving form of the traditional cutting mechanism is relatively simple, and multiple drivers are required for multiple moving parts, resulting in high production costs.

[0005] To solve the above-mentioned technical problems, the present invention proposes a transmission component, comprising:

[0006] The guide component has a protruding mating part on its outer peripheral wall;

[0007] A transmission component has a mounting hole and an annular groove on the inner wall of the mounting hole; along the circumference of the mounting hole, the annular groove includes a first helical segment and a second helical segment connected end to end; the first helical segment and the second helical segment have opposite helical directions, and the connection points at their two ends respectively form a first turning part and a second turning part;

[0008] Along the axial direction of the mounting hole, the first steering portion and the second steering portion are separated by a first distance, which is greater than 0.

[0009] The transmission component is sleeved on the outside of the guide component through the mounting hole, and the mating part extends into the annular groove; the transmission component rotates relative to the guide component under the drive force and reciprocates within the annular groove.

[0010] Optionally, in the above-mentioned transmission assembly, the annular groove further includes a first arc segment disposed between the first helical segment and the second helical segment, serving as the first steering part, wherein the first arc segment is arranged perpendicular to the axial direction of the mounting hole;

[0011] The first end of the first spiral segment away from the second turning part and the second end of the second spiral segment away from the second turning part are respectively fixed to the two ends of the first arc segment;

[0012] Along the axial direction of the mounting hole, the first end and the second end are respectively separated from the second turning part by a second spacing and a third spacing, both of which are greater than 0.

[0013] Optionally, in the above-mentioned transmission assembly, the annular groove further includes a second arc segment disposed between the first helical segment and the second helical segment, serving as the second steering part, wherein the second arc segment is arranged perpendicular to the axial direction of the mounting hole;

[0014] Along the axial direction of the mounting hole, the second arc segment is separated from the first arc segment by a fourth distance, the fourth distance being greater than 0.

[0015] Optionally, in the above-described transmission assembly, both the first arc segment and the second arc segment are minor arcs; and / or,

[0016] The arc angle of the first arc segment is the same as that of the second arc segment.

[0017] Optionally, in the above-mentioned transmission assembly, the transmission component includes a first transmission part and a second transmission part that are detachably connected. The first transmission part and the second transmission part are each provided with a first groove and a second groove with opposite openings on opposite sides. The first groove and the second groove together enclose and form the annular slide groove.

[0018] One of the first transmission part and the second transmission part is provided with a positioning groove, and the other is provided with a positioning protrusion that engages with the positioning groove. The positioning protrusion is engaged in the positioning groove to restrict the first transmission part and the second transmission part from rotating relative to each other in the circumferential direction along the mounting hole.

[0019] The present invention also provides a cutting mechanism, comprising:

[0020] Base;

[0021] A fixed cutting tool is mounted on the base;

[0022] The aforementioned transmission components;

[0023] The moving tool is mounted on the transmission component of the transmission assembly and is driven by the transmission component to reciprocate relative to the fixed tool.

[0024] Optionally, in the above-mentioned cutting mechanism, one of the transmission member and the moving cutter is provided with a groove, and the other is provided with a protrusion that engages with the groove; when the transmission member rotates relative to the guide member under the drive of the driving force, the protrusion and the groove engage, driving the moving cutter to reciprocate along the axial direction of the mounting hole.

[0025] The present invention also provides a roller brush device, comprising:

[0026] The roller brush body; and,

[0027] The cutting mechanism described above includes a base comprising a roller, which is rotatably mounted on the brush body. The transmission component is located inside the roller, and its mounting hole extends along the axial direction of the roller.

[0028] The rotation of the drum drives the transmission component to rotate relative to the guide component and reciprocate within the annular groove. Driven by the guide component, the moving cutter of the cutting mechanism reciprocates along the axial direction of the drum.

[0029] Optionally, in the above-mentioned roller brush device, the moving cutter is provided with an elongated hole extending along the axial direction of the roller, and a positioning post protrudes from the inner side of the roller. The positioning post passes through the elongated hole and can slide relative to the elongated hole.

[0030] The present invention also provides a cleaning device, including the above-described roller brush device.

[0031] The technical solution provided by this invention has the following advantages:

[0032] The transmission assembly provided by this invention comprises a cooperating guide and a transmission component. The guide has a mating portion, and the transmission component has an annular groove. By inserting the mating portion into the annular groove, when the transmission component rotates relative to the guide under the driving force, the annular groove can rotate relative to the mating portion. Simultaneously, the mating portion abuts against the groove wall of the annular groove, thus acting on the annular groove. Furthermore, the annular groove includes a first helical segment and a second helical segment, and the distance between the beginning and end of the first and second helical segments along the axial direction of the mounting hole is greater than 0. Therefore, when the annular groove slides relative to the mating portion, the mating portion always abuts against the groove wall of the annular groove, allowing the transmission component to be displaced axially along the mounting hole. Further, the helical directions of the first and second helical segments are opposite. For example, when the mating part slides along the first helical segment, it drives the transmission member to move to the left along the axial direction of the mounting hole. When the mating part slides along the second helical segment, it drives the transmission member to move to the right along the axial direction of the mounting hole, so that the transmission member can reciprocate along the axial direction of the mounting hole, converting the rotational motion of the transmission member into linear reciprocating motion. The structure is simple and the driving method of the driver is more flexible. Moreover, it can be understood that if this transmission component is applied to the roller brush device, the transmission member can be connected to the roller brush, converting the rotational motion of the roller brush into the linear motion of the transmission member. If the moving cutter is then connected to the transmission member, it can drive the moving cutter to reciprocate linearly to perform a cutting action to cut the hair wrapped on the roller brush. There is no need to set up a separate driver to drive the moving cutter, which makes the structure simpler and the cost lower. Attached Figure Description

Detailed Implementation

[0049] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0050] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0051] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0052] This invention provides a transmission component, a cutting mechanism, a roller brush device, and a cleaning equipment. Figures 1 to 13 Examples of the transmission components, cutting mechanisms, roller brush devices, and cleaning equipment provided by the present invention.

[0053] Example 1

[0054] See also Figures 1 to 3 This embodiment provides a transmission assembly 200, which can be connected to a driver to transmit and convert the driving force of the driver, enabling the movable part (i.e., the component to be driven) to move in a direction that meets the user's needs. The transmission assembly 200 includes a guide 1 and a transmission component 2. The guide 1 guides the movement of the transmission component 2, and the transmission component 2 is connected to the driver to transmit the driving force of the driver and drive the movable part to move.

[0055] Specifically, in combination Figures 11 to 13A mating part 11 protrudes from the outer peripheral wall of the guide member 1, and acts on the transmission member 2 through the mating part 11. The transmission member 2 has a mounting hole 21 and an annular groove 22 provided on the inner wall of the mounting hole 21. Along the circumferential direction of the mounting hole 21, the annular groove 22 includes a first helical segment 221 and a second helical segment 222 connected end to end. The helical directions of the first helical segment 221 and the second helical segment 222 are opposite, and the connection points at their ends respectively form a first turning part 223 and a second turning part 224. Along the axial direction of the mounting hole 21, the distance between the first turning part 223 and the second turning part 224 is a distance of a certain value. A gap, the first gap is greater than 0; the transmission component 2 is sleeved on the outside of the guide component 1 through the mounting hole 21, and the mating part 11 extends into the annular slide groove 22; the transmission component 2 rotates relative to the guide component 1 under the drive force, and the mating part 11 on the guide component 1 moves relative to the first spiral segment 221 and the second spiral segment 222. Since the guide component 1 is fixed, the mating part 11 will not move under the action of the first spiral segment 221 or the second spiral segment 222, but under the action of the mating part 11, it pushes the transmission component 2 to reciprocate along the axial direction of the mounting hole 21, that is, to reciprocate within the annular slide groove 22.

[0056] The transmission assembly 200 provided by the present invention comprises a guide member 1 and a transmission member 2 that cooperate with each other. A mating part 11 is provided on the guide member 1, and an annular groove 22 is provided on the transmission member 2. By extending the mating part 11 into the annular groove 22, when the transmission member 2 rotates relative to the guide member 1 under the drive of a driving force, the annular groove 22 can rotate relative to the mating part 11. Simultaneously, the mating part 11 can abut against the groove wall of the annular groove 22 to act on the annular groove 22. Furthermore, the annular groove 22 includes a first helical segment 221 and a second helical segment 222, and the distance between the beginning and end ends of the first helical segment 221 and the second helical segment 222 along the axial direction of the mounting hole 21 is greater than 0. Therefore, the annular groove 22... When the groove 22 slides relative to the mating part 11, the mating part 11 always abuts against the groove wall of the annular groove 22, so that the transmission member 2 can be displaced along the axial direction of the mounting hole 21. Furthermore, the helical directions of the first helical segment 221 and the second helical segment 222 are opposite. For example, when the mating part 11 slides along the first helical segment 221, it drives the transmission member 2 to move to the left along the axial direction of the mounting hole 21. When the mating part 11 slides along the second helical segment 222, it drives the transmission member 2 to move to the right along the axial direction of the mounting hole 21, so that the transmission member 2 can reciprocate along the axial direction of the mounting hole 21, converting the rotational motion of the transmission member 2 into linear reciprocating motion. The structure is simple and makes the driving mode of the driver more flexible.

[0057] Furthermore, the aforementioned transmission component 2 includes a first transmission part 23 and a second transmission part 24 that are detachably connected, to facilitate the installation of the mating part 11 of the guide component 1 into the annular groove. Specifically, please refer to [reference needed]. Figures 11 to 13A first mounting hole is provided on the first transmission part 23, and a second mounting hole corresponding to the first mounting hole is provided on the second transmission part 24. Multiple first and second mounting holes can be provided. The first transmission part 23 and the second transmission part 24 can be connected by a connecting member passing through the first and second mounting holes. The connecting member can be a screw or bolt, etc. On opposite sides of the first transmission part 23 and the second transmission part 24, there are first grooves 231 and second grooves 241 with opposing openings. The first grooves 231 and second grooves 241 together form an annular groove 22. The first spiral segment 221 and... The second spiral segment 222 can be formed on the groove sidewalls of the first groove 231 and the second groove 241 respectively. The mounting holes 21 can be symmetrically distributed on the first transmission part 23 and the second transmission part 24. Moreover, one of the first transmission part 23 and the second transmission part 24 is provided with a positioning groove 242, and the other is provided with a positioning protrusion 232 that engages with the positioning groove 242. The positioning protrusion 232 is engaged in the positioning groove 242 to restrict the relative rotation of the first transmission part 23 and the second transmission part 24 along the circumference of the mounting hole 21, and also to facilitate the positioning and assembly of the first transmission part 23 and the second transmission part 24. When assembling the transmission assembly 200, the guide member 1 can be first placed into the mounting hole 21 on the first transmission part 23 or the second transmission part 24, so that the mating part 11 is accommodated in the first groove 231 or the second groove 241. Then, the positioning protrusion 232 on the second transmission part 24 or the first transmission part 23 is engaged in the corresponding positioning groove 242. The positioning protrusion 232 extends axially toward the mounting hole 21, so that the first transmission part 23 and the second transmission part 24 are initially positioned. Then, the first transmission part 23 and the second transmission part 24 are locked by the connector, and the first transmission part 23 and the second transmission part 24 are assembled and can rotate relative to the guide member 1. The first transmission part 23 and the second transmission part 24 can both be made into square blocks and arranged symmetrically about the guide member 1. The shapes of the first transmission part 23 and the second transmission part 24 can be the same or different, and can be adapted to the actual applicable space.

[0058] The guide component 1 described above can be configured in various ways. Preferably, it can be combined with... Figure 10 and Figure 11 The guide member 1 can be configured as a guide shaft, cylindrical in shape, to facilitate smoother rotation of the transmission member 2 relative to it. The mating part 11 on the guide member 1 can be a protrusion 111 protruding from the outer wall of the guide shaft. The shape of the protrusion 111 matches the shape of the sidewall of the annular groove, and can be square, circular, or irregular. When the transmission member 2 rotates relative to the guide shaft, the groove wall of the annular groove abuts against the protrusion 111. Under the action of the protrusion 111, the transmission member 2 continuously reciprocates along the guide shaft, thereby driving the movable part to reciprocate, converting the rotational motion of the driver into continuous linear reciprocating motion to meet the movement requirements of the movable part.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that the transmission assembly 200 described above can also realize the intermittent reciprocating movement of the moving part to suit different usage requirements.

[0061] In this embodiment, please refer to Figure 7 The annular groove 22 also includes a first arc segment 2231 disposed between the first helical segment 221 and the second helical segment 222, serving as a first steering portion 223; the first end of the first helical segment 221 away from the second steering portion 224 and the second end of the second helical segment 222 away from the second steering portion 224 are respectively fixed to the two ends of the first arc segment 2231; the first arc segment 2231 is arranged perpendicular to the axial direction of the mounting hole 21, and when the mating portion 11 on the guide member 1 slides over the first arc segment 2231, the mating portion 11 fits against the first arc segment 2231 without abutting against the transmission member 2 along the mounting hole 21. The axial movement of the transmission member 2 causes the moving part to remain stationary during this period. Along the axial direction of the mounting hole 21, the first end and the second end are respectively separated from the second steering part 224 by a second distance and a third distance, both of which are greater than 0. When the transmission member 2 continues to rotate, causing the mating part 11 on the guide member 1 to slide over the first arc segment 2231 and enter the first spiral segment 221 or the second spiral segment 222, the mating part 11 abuts against the first spiral segment 221 or the second spiral segment 222, causing the transmission member 2 to be displaced in the axial direction of the mounting hole 21, thereby driving the moving part to move.

[0062] The aforementioned first arc segment 2231 can be referred to as the idle stroke segment of the transmission component 2. The first helical segment 221, the first arc segment 2231, and the second helical segment 222 form one complete active cycle of the transmission component 2. It can be understood that within one cycle of active stroke, one or more idle stroke segments can be set according to the movement mode of the component to be moved. Preferably, they can be combined... Figure 5 , Figure 6 and Figure 8The transmission component 2 can be provided with two idle stroke segments in each active cycle. Specifically, the annular groove 22 also includes a second arc segment 2241 located between the first spiral segment 221 and the second spiral segment 222, serving as a second steering part 224. The second arc segment 2241 is also arranged perpendicular to the axial direction of the mounting hole 21. When the mating part 11 on the guide component 1 slides over the second arc segment 2241, the mating part 11 engages with the second arc segment 2241 without abutting the transmission component 2 as it moves axially along the mounting hole 21. Therefore, the component to be moved... During this period, the device remains stationary. Along the axial direction of the mounting hole 21, the second arc segment 2241 and the first arc segment 2231 are separated by a fourth distance, which is greater than 0. When the transmission component 2 continues to rotate, causing the mating part 11 on the guide component 1 to slide past the second arc segment 2241 and enter the first spiral segment 221 or the second spiral segment 222, the mating part 11 abuts against the first spiral segment 221 or the second spiral segment 222, causing the transmission component 2 to be displaced in the axial direction of the mounting hole 21, thereby driving the movable component to move.

[0063] The first spiral segment 221, the first arc segment 2231, the second spiral segment 222, and the second arc segment 2241 are sequentially connected end to end. In this case, one complete cycle of the transmission component 2 is as follows: When the transmission component 2 is in its initial position, after rotating, the mating part 11 first slides over the first spiral segment 221. When the transmission component 2 slides over the first spiral segment 221, it can move to the left along the guide 1, and then enter the first arc segment 2231. The transmission component 2 stops moving. When the mating part 11... When the mating part 11 enters the second spiral segment 222, it drives the transmission member 2 to move to the right along the guide member 1, so that the transmission member 2 returns to its initial position. Finally, when the mating part 11 slides into the second arc segment 2241, the transmission member 2 remains stationary. When the transmission member 2 continues to rotate, the transmission member 2 enters the next cycle of its active stroke, and so on. The direction of movement of the transmission member 2 is not limited, but when the mating part 11 slides through the first spiral segment 221 and the second spiral segment 222, the direction of movement of the transmission member 2 is opposite.

[0064] Furthermore, when two idle stroke segments are set, the first arc segment 2231 and the second arc segment 2241 are both minor arcs to ensure that the transmission component 2 can reciprocate. The movement range of the transmission component 2 can be adjusted and controlled according to the arc angle of the first arc segment 2231 and the second arc segment 2241.

[0065] Moreover, it can be combined Figure 6 and Figure 8The arc angles of the first arc segment 2231 and the second arc segment 2241 can be the same, ensuring that the distance the transmission component 2 moves to the left and to the right along the guide component 1 is the same, thus driving the component to be moved to move uniformly left and right. Of course, the left and right directions mentioned above are just examples; other directions such as front and back, up and down, or others can also be used, depending on the requirements. The travel distance of the transmission component 2 can be adjusted by the size of the arc angles of the first arc segment 2231 and the second arc segment 2241 to control the movement range of the component to be moved.

[0066] Example 3

[0067] See also Figure 3 and Figure 4 This embodiment provides a cutting mechanism 300, which includes a base, a fixed cutter 32, a movable cutter 31, and a transmission assembly 200 as described in the above embodiments. The base is used for mounting the transmission assembly 200. The movable cutter 31 is disposed on the transmission member 2 of the transmission assembly 200 and is driven by the transmission member 2 to reciprocate relative to the fixed cutter 32, thereby cooperating with the fixed cutter 32 to perform a cutting action.

[0068] The form of the base is not limited. For example, the base can be a support, a support plate, or a rotating table. When the base is a support, the guide 1 of the transmission assembly 200 can be fixed on the support, the transmission component 2 of the transmission assembly 200 is rotatably mounted on the guide 1, the moving tool 31 is fixed on one side of the transmission component 2, and the fixed tool 32 is fixed on the support and is correspondingly mounted to the moving tool 31.

[0069] At this time, the fixed cutter 32 and the moving cutter 31 can both be arranged in a serrated or wavy shape, and both the fixed cutter 32 and the moving cutter 31 extend along the extension direction of the guide member 1. The fixed cutter 32 and the moving cutter 31 can both be set as a blade-shaped serrated blade. The moving cutter 31 is driven to move back and forth relative to the fixed cutter 32 through the transmission member 2, similar to the principle of an electric razor, to cut hair or other objects.

[0070] Furthermore, it can be combined with Figure 3 and Figure 5 The fixed cutter 32 and the transmission component 2 are connected by a slot 25 and a protrusion 311 for easy disassembly and maintenance. Specifically, one of the transmission component 2 and the moving cutter 31 is provided with a slot 25, and the other is provided with a protrusion 311 that engages with the slot 25. When the transmission component 2 rotates relative to the guide component 1 under the drive force, the engagement of the protrusion 311 and the slot 25 drives the moving cutter 31 to reciprocate along the axial direction of the mounting hole 21, so that the moving cutter 31 reciprocates relative to the fixed cutter 32 to perform cutting.

[0071] Specifically, for ease of installation, it can be combined with Figure 5 and Figure 6 A connector is provided at the end of the first transmission part 23. The aforementioned slot 25 is provided on the connector, and the thickness of the connector is the sum of the thicknesses of the first transmission part 23 and the second transmission part 24, thereby ensuring the connection strength. Moreover, two of the aforementioned moving cutter 31 and fixed cutter 32 can be provided. The two moving cutters 31 and the two fixed cutters 32 are arranged in a one-to-one correspondence. The two moving cutters 31 are located on opposite sides of the guide member 1, thereby performing bidirectional cutting and achieving higher cutting efficiency. At this time, two slots 25 are provided, located on opposite sides of the connector, and the locking protrusion 311 on each moving cutter 31 is correspondingly locked in one slot 25.

[0072] In this embodiment, the fixed cutter 32 is fixed on the base and the moving cutter 31 is connected to the transmission component 2. The linear reciprocating motion of the transmission component 2 drives the moving cutter 31 to reciprocate relative to the fixed cutter 32, thereby achieving cutting. The structure is simple and the cutting efficiency is higher.

[0073] Example 4

[0074] See also Figures 1 to 3 This embodiment provides a roller brush device 1000 for cleaning floors. The roller brush device 1000 includes a roller brush body 100 and the aforementioned cutting mechanism 300. When the roller brush device 1000 cleans the floor or a carpet, it is easy for hair or other filamentous materials to get tangled. The cutting mechanism 300 cuts the hair on the roller brush, making the roller brush easy to clean. In this embodiment, the cutting mechanism 300 on the roller brush device 1000 can continuously and uninterruptedly cut the hair or other filamentous materials on the brush.

[0075] The roller brush body 100 may include a housing and a driver or other auxiliary structure disposed within the housing, and shall fix the cutting mechanism 300 thereon.

[0076] When the cutting mechanism 300 is applied to the roller brush device 1000, the base of the cutting mechanism 300 may include a roller 33, which is rotatably mounted on the roller brush body 100 and driven to rotate by a driver inside the roller brush body 100. A brush may be provided on the outer wall of the roller 33 to clean the ground. At this time, the transmission member 2 is provided inside the roller brush and is driven to rotate by the rotation of the roller brush. Moreover, the installation of the transmission member 2 must ensure that the mounting hole 21 extends along the axial direction of the roller 33. When the driver inside the roller brush body 100 drives the roller 33 to rotate, the roller 33 drives the transmission member 2 to rotate relative to the guide member 1. Under the action of the mating part 11 of the guide member 1, the transmission member 2 makes a linear reciprocating motion relative to the guide member 1, which drives the moving cutter 31 to move reciprocally. A through hole may be provided on the side wall of the roller 33, and both the moving cutter 31 and the fixed cutter 32 can at least partially extend out of the through hole to cut the hair wrapped around the brush.

[0077] Furthermore, to facilitate the installation of the roller 33, which includes an upper roller body and a lower roller body connected to each other, two through holes are formed at the two ends of the upper roller body and the lower roller body respectively, for the moving cutter and the fixed cutter to extend out. A moving cutter 31 and a fixed cutter 32 are provided corresponding to one of the through holes. The fixed cutter 32 is fixed on the roller 33 and at least partially extends out of the through hole. The moving cutter 31 is connected to the transmission component 2 inside the roller 33. The moving cutter 31 is driven to reciprocate by the movement of the transmission component 2. The roller 33 is provided with moving cutter 31 and fixed cutter 32 on both sides, which can cut the hair on the brush from both sides, resulting in a better cutting effect and making the roller brush device 1000 easier to clean.

[0078] Furthermore, it can be combined with Figure 3 and Figure 4 The moving cutter 31 has an elongated hole 312 extending along the axial direction of the roller 33. A positioning post 331 protrudes from the inner side of the roller 33 and passes through the elongated hole 312. The positioning post 331 can slide relative to the elongated hole 312, ensuring more stable movement of the moving cutter 31 and preventing it from shaking. Moreover, multiple elongated holes 312 and multiple positioning posts 331 can be provided. Multiple elongated holes 312 or multiple positioning posts 331 are arranged at intervals along the axial direction of the roller 33, making the moving cutter 31 more stable during the cutting process and improving the cutting effect.

[0079] In this embodiment, a transmission component 2 is provided inside the roller 33 of the roller brush device 1000. The roller 33 is driven to rotate by a driver inside the roller brush body 100. The rotation of the roller 33 drives the transmission component 2 to rotate, so that the transmission component 2 can reciprocate along the axial direction of the roller brush body 100 under the action of the guide component 1. This drives the moving cutter 31 to reciprocate along the axial direction of the roller 33 to cut hair. The rotation of the roller 33 of the roller brush device 1000 and the rotation of the moving cutter 31 for cutting hair are both driven by a single driver, which effectively saves costs. Moreover, the roller brush device 1000 can not only clean the ground, but also make the hair on the bristles easy to clean, which can effectively extend the service life of the roller brush device 1000.

[0081] This embodiment also provides a roller brush device 1000, which can be combined with... Figure 1 , Figure 9 and Figure 10 The difference between this roller brush device 1000 and the roller brush device 1000 mentioned above is that the moving blade 31 on the roller brush device 1000 can perform intermittent reciprocating motion. When the roller brush device 1000 cleans areas such as blankets, the continuous cutting action of the moving blade 31 may accidentally damage the blankets.

[0082] In this embodiment, the other structures of the roller brush device 1000 are the same as those of the roller brush device 1000 in Embodiment 4. The difference is that in this embodiment, the annular groove of the transmission member 2 in the cutting mechanism 300 of the roller brush device 1000 may include a first arc segment 2231, a first spiral segment 221 and a second spiral segment 222, or the annular groove of the transmission member 2 may include a first arc segment 2231, a first spiral segment 221, a second arc segment 2241 and a second spiral segment 222, so that the transmission member 2 has a certain idle stroke section, so that the moving cutter 31 has a period of time to stop cutting, thereby avoiding cutting the blanket and improving the user experience.
