Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a reversing mechanism. Based on this, it also specifically relates to a cutting unit, a roller brush device, and a cleaning equipment. Background Technology

[0002] Currently, cleaning equipment such as sweepers and vacuum cleaners typically use roller brushes located at the bottom to clean the floor. However, during the cleaning process, the roller brush is prone to getting tangled with hair and other filamentous materials. When too many filamentous materials are tangled on the roller brush, it will affect the cleaning effect of the roller brush, and may even jam the roller brush, causing the motor to stall and eventually damage the motor.

[0003] Currently, existing technologies incorporate a cutting unit within the roller brush. This cutting unit typically includes a reversing mechanism and blades. The reversing mechanism drives the blades to reciprocate, cutting away any filaments wrapped around the roller brush and ensuring it remains free of tangled filaments, allowing the roller brush to perform its cleaning function normally. However, existing reversing mechanisms suffer from a relatively short service life. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of short service life of the reversing mechanism in the prior art.

[0005] To achieve the above objectives, this utility model provides a reversing mechanism, comprising: a transmission member, wherein a first annular groove is formed on the outer wall of the transmission member, and the plane of the first annular groove is inclined relative to the axial direction of the transmission member; a mating member, at least a portion of the mating member being disposed within the first annular groove; and a moving assembly, the moving assembly comprising an annular ring sleeved on the outer side of the transmission member, a rocker arm connected to the outer peripheral wall of the annular ring, and a moving member connected to the rocker arm, wherein a second annular groove is formed on the inner wall of the annular ring, and the second annular groove accommodating at least a portion of the mating member; wherein the mating member is rotatable within the first annular groove and / or the second annular groove, and the moving assembly is configured to reciprocate when the transmission member rotates.

[0006] In some embodiments, the mating element includes a plurality of balls.

[0007] In some embodiments, the movable member has a connecting cavity into which at least a portion of the rocker arm extends.

[0008] In some embodiments, the rocker arm has an arcuate surface that contacts the connecting cavity.

[0009] Based on this, the present invention also provides a cutting unit, including: a fixed cutter; the aforementioned reversing mechanism; and a movable cutter, wherein the movable cutter is connected to the moving component, and the movable cutter is configured to reciprocate relative to the fixed cutter via the moving component.

[0010] In some embodiments, the cutting unit further includes a clamping mechanism disposed on the side of the fixed cutter away from the moving cutter, the clamping mechanism being configured to provide a force to the fixed cutter close to the moving cutter.

[0011] This utility model also provides a roller brush device, including: a roller brush body; the aforementioned cutting unit, the cutting unit being disposed within the roller brush body, the transmission member being capable of being pulsatorically connected to the roller brush body; and a rotating end cap assembly, the rotating end cap assembly being pulsatorically connected to one end of the roller brush body to drive the roller brush body to rotate, the rotation of the roller brush body driving the transmission member to rotate.

[0012] In some embodiments, the roller brush device further includes a speed reduction mechanism that is kinetically connected to both the transmission member and the roller brush body.

[0013] In some embodiments, the roller brush device further includes a cleaning component disposed on the outer peripheral wall of the roller brush body.

[0014] This utility model also provides a cleaning device, including the aforementioned roller brush device.

[0015] In the reversing mechanism provided by this utility model, a first annular groove is formed on the outer wall of the transmission component. The plane containing the first annular groove is inclined relative to the axial direction of the transmission component. The moving component includes an annular ring sleeved on the outside of the transmission component, a rocker arm connected to the outer peripheral wall of the annular ring, and a moving component connected to the rocker arm. A second annular groove is formed on the inner wall of the annular ring, and a mating component is accommodated in the first and second annular grooves. When the transmission component rotates under the drive force, the first annular groove rotates with the transmission component, thereby applying at least an axial force to the mating component disposed in the first annular groove. Through the mating component, an axial force is further applied to the second annular groove, driving the moving component to move along the axial direction of the transmission component. As the transmission component continues to rotate, the moving direction of the moving component changes periodically, realizing the reciprocating movement of the moving component. Furthermore, since the mating component can rotate within the first annular groove and / or the second annular groove, the contact surface between the mating component and the first annular groove and / or the second annular groove remains variable. That is, during the rotation of the mating component, it can form multi-point contact with the first annular groove and / or the second annular groove, thereby reducing the wear rate of the mating component, extending the service life of the mating component, and thus extending the service life of the reversing mechanism.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Existing cleaning equipment, such as sweepers and vacuum cleaners, typically has a roller brush at its base. This rotating brush cleans the floor. However, during cleaning, hair and other fibrous materials easily become entangled in the roller brush. Excessive entanglement can impair cleaning effectiveness, even jamming the brush, causing motor blockage, and ultimately damaging the motor and rendering the equipment unusable. To address this, a cutting unit is usually included in the roller brush. This unit mainly consists of a reversing mechanism and blades. The reversing mechanism drives the blades to reciprocate, cutting the fibrous material entangled in the brush. However, existing reversing mechanisms suffer from severe wear on the reversing components, resulting in a short lifespan.

[0029] To solve the above-mentioned technical problems, this utility model provides a reversing mechanism 1, which has the advantage of a long service life.

[0030] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, according to one embodiment of the reversing mechanism 1 of this utility model, the reversing mechanism 1 includes: a transmission member 101, a mating member, and a moving assembly, such as... Figure 2As shown, a first annular groove 1012 is formed on the outer wall of the transmission component 101. The plane containing the first annular groove 1012 is inclined relative to the axial direction of the transmission component 101, and at least part of the mating parts are disposed within the first annular groove 1012. See also Figure 1 As shown, the moving assembly includes an annular ring 103, a swing rod 104, and a moving member 105 connected in sequence. The annular ring 103 is sleeved on the outside of the transmission member 101, and in conjunction with... Figure 1 and Figure 4 As shown, the annular ring 103 can be fitted onto the outer side of the first annular groove 1012. A second annular groove 1031 is formed on the inner wall of the annular ring 103. The second annular groove 1031 contains at least a portion of the mating parts, that is, the mating parts can abut against the first annular groove 1012 and the second annular groove 1031 respectively. One end of the rocker arm 104 is connected to the outer peripheral wall of the annular ring 103, and the other end is connected to the moving part 105. The mating parts can rotate within the first annular groove 1012 and / or the second annular groove 1031. The moving part is configured to reciprocate when the transmission part 101 rotates.

[0031] In the reversing mechanism 1 provided by this utility model, a first annular groove 1012 is formed on the outer wall of the transmission member 101. The plane where the first annular groove 1012 is located is inclined relative to the axial direction of the transmission member 101. The moving component includes an annular ring 103 sleeved on the outside of the transmission member 101, a rocker arm 104 connected to the outer peripheral wall of the annular ring 103, and a moving member 105 connected to the rocker arm 104. A second annular groove 1031 is formed on the inner wall of the annular ring 103. The mating component is accommodated in the first annular groove 1012 and the second annular groove 1031. When the transmission component 101 rotates under the driving force, the first annular groove 1012 rotates with it. Since the plane of the first annular groove 1012 is inclined relative to the transmission component 101, when the first annular groove 1012 rotates with the transmission component 101, it applies at least an axial force to the mating component within it. This force, in turn, applies an axial force to the second annular groove 1031. This force drives the annular ring 103, the rocker arm 104, and the moving component 105 to move axially, causing the moving assembly to move along the axial direction of the transmission component 101. As the transmission component 101 continues to rotate, the direction of movement of the moving assembly changes periodically, achieving reciprocating movement of the moving assembly. Furthermore, since the mating component can rotate within the first annular groove 1012 and / or the second annular groove 1031, the contact surface between the mating component and the first annular groove 1012 and / or the second annular groove 1031 remains variable. That is, during the rotation of the mating component, it can form multi-point contact with the first annular groove 1012 and / or the second annular groove 1031, thereby reducing the wear rate of the mating component, extending the service life of the mating component, and thus extending the service life of the reversing mechanism. At the same time, it also reduces the cost of replacing the reversing mechanism 1.

[0032] In this invention, the mating components include, but are not limited to, cylinders, ball bearings 102, etc., as long as they can rotate within the first annular groove 1012 and / or the second annular groove 1031. For example, the mating components may include multiple cylinders, the arcuate surfaces of which can respectively abut against the first annular groove 1012 and / or the second annular groove 1031. The cylinders are accommodated within the accommodating space formed by the first annular groove 1012 and the second annular groove 1031, such that the axial direction of the cylinders extends parallel to the axial direction of the transmission component 101. Alternatively, according to a preferred embodiment of the reversing mechanism of this invention, see [reference needed]. Figure 1 and Figure 4As shown, the mating component includes multiple balls 102. When the transmission component 101 rotates, because the plane of the first annular groove 1012 is inclined relative to the transmission component 101, the first annular groove 1012 applies at least part of a force along the axial direction of the transmission component 101 to the balls. This force is transmitted sequentially through the balls 102 to the annular ring 103, the rocker arm 104, and the moving component 105, thereby realizing the axial movement of the moving component. As the transmission component 101 continues to rotate, the axial movement direction of the moving component changes periodically, thus realizing the reversal of the axial movement of the moving component. Since the balls 102 are spherical, they also rotate during the rotation of the transmission component 101, further reducing the wear of the balls and extending the service life of the reversing mechanism 1.

[0033] In some implementations, see Figure 1 and Figure 2 As shown, the transmission component 101 is a roughly cylindrical rod, which facilitates the rotation of the transmission component 101 after being driven by a driving force. The first annular groove 1012 is provided on the outer circumferential surface of the rod.

[0034] In some implementations, see Figure 1 and Figure 2 As shown, the transmission component 101 has a protrusion 1011, and a first annular groove is formed on the outer circumferential surface of the protrusion 1011. The size of the transmission component 101 at the protrusion 1011 is larger than the size of the rest of the transmission component 101. For example, when the transmission component 101 is a cylindrical rod, the diameter of the transmission component 101 at the protrusion 1011 is larger than the diameter of the transmission component 101 in the rest of the transmission component. This gives the transmission component 101 greater structural strength at the protrusion 1011, ensuring that the moving assembly can perform stable reciprocating movement. (Refer to...) Figure 2 As shown, according to one embodiment of the reversing mechanism of this utility model, the protrusion 1011 is spherical, and the diameter of the sphere is larger than the diameter of the transmission member 101 at the non-protrusion 1011.

[0035] In some implementations, refer to Figure 1 and Figure 4 As shown, the movable member 105 has a connecting cavity 1051, and at least part of the swing rod 104 extends into the connecting cavity 1051, thereby realizing the transmission connection between the movable member 105 and the swing rod 104, and thus the movable member 105 can be driven to reciprocate through the swing rod 104.

[0036] In some implementations, refer to Figure 1 and Figure 4As shown, the end of the rocker arm 104 near the annular ring 103 has a reduced diameter portion, and the diameter of the other end of the rocker arm 104 away from the annular ring 103 is larger than the diameter of the reduced diameter portion. Simultaneously, the diameter of the inlet of the connecting cavity 1051 matches the diameter of the reduced diameter portion. Thus, after the rocker arm 104 and the moving member 105 are assembled, the rocker arm 104 is less likely to detach from the connecting cavity 1051, ensuring the stability of the reciprocating movement of the moving member 105.

[0037] In some implementations, see Figure 1 As shown, the rocker arm 104 has an arc-shaped surface that contacts the connecting cavity 1051. In this way, during the transmission movement of the rocker arm 104 and the moving part 105, the wear of the rocker arm 104 can be reduced, and the service life of the reversing mechanism 1 can be further extended.

[0038] This utility model also provides a cutting unit 2, as shown in the reference. Figure 4 As shown, the cutting unit 2 includes: the aforementioned reversing mechanism 1, a moving cutter 201 connected to the moving component of the reversing mechanism 1, and a fixed cutter 202. The moving cutter 201 is connected to the moving component, and the fixed cutter 202 is fixedly positioned relative to the moving cutter 201. When the reversing mechanism 1 is working, the moving component reciprocates, thereby driving the moving cutter 201 to reciprocate, causing the moving cutter 201 to reciprocate relative to the fixed cutter 202, thus completing the cutting operation.

[0039] In some embodiments, the cutting unit 2 further includes a clamping mechanism disposed on the side of the fixed cutter 202 away from the moving cutter 201. The clamping mechanism is configured to provide a force to the fixed cutter 202 close to the moving cutter 201. In this way, the fixed cutter 202 can be more closely pressed against the moving cutter 201, providing a cutting clamping force to the moving cutter 201, thereby improving the cutting effect of the moving cutter 201.

[0040] In some embodiments, the number of moving cutter 201 and fixed cutter 202 is at least one. When the number of moving cutter 201 and fixed cutter 202 is multiple, each moving cutter 201 corresponds to one fixed cutter 202 to ensure the cutting effect of the cutting unit 2.

[0041] In some implementations, see Figure 4As shown, the moving cutter 201 is connected to the moving component 105 of the moving assembly, and the moving cutter 201 is connected to the side of the moving component 105 away from the swing arm 104. Thus, while the moving component 105 reciprocates, it drives the moving cutter 201 to reciprocate. In this invention, the connection method between the moving component 105 and the moving cutter 201 is not limited, as long as transmission between them can be achieved. For example, the moving component 105 and the moving cutter 201 can be connected by a snap-fit ​​connection. Specifically, the sides of the moving component 105 and the moving cutter 201 that are close to each other are respectively formed with a slot and a buckle. Through the snap-fit ​​engagement of the slot and the buckle, the moving component 105 and the moving cutter 201 are connected together; this also facilitates the installation and disassembly of the moving cutter 201 and the moving component 105, which is beneficial for subsequent maintenance and replacement work.

[0042] In some implementations, such as Figure 4 As shown, the moving cutter 201 and the fixed cutter 202 have serrated or wavy blades that extend along the axial direction of the transmission member 101. The transmission member 101 rotates, driving the moving component to reciprocate, which in turn causes the blade of the moving cutter 201 to reciprocate relative to the blade of the fixed cutter 202, thereby achieving the cutting operation.

[0043] In some embodiments, the cutting unit 2 may also include a base for mounting the aforementioned reversing mechanism 1, moving cutter 201 and fixed cutter 202. The base may include, but is not limited to, a support base, a support plate, a rotating table, and the roller brush body 301 described below.

[0044] This utility model also provides a roller brush device 3, which includes: the aforementioned cutting unit 2, roller brush body 301, and rotating end cap assembly 302, as shown in the figure. Figure 3 and Figure 4 As shown, the cutting unit 2 is disposed inside the roller brush body 301, the rotating end cap assembly 302 is connected to one end of the roller brush body 301, and the transmission component 101 is disposed inside the roller brush body 301 and connected to the roller brush body 301. The rotating end cap assembly 302 rotates when driven by a driving force, such as a motor driving force, which drives the roller brush body 301 to rotate, thereby driving the reversing mechanism 1 to work, so that the cutting unit 2 starts cutting.

[0045] In some implementations, refer to Figure 4 As shown, the roller brush device 3 also includes a reduction mechanism 304 that is connected to the transmission component 101 and the roller brush body 301 respectively. The reduction mechanism 304 can reduce the rotational speed of the transmission component 101 and increase the torque of the transmission component 101, which is beneficial to improving the movement stability and cutting effect of the moving tool 201.

[0046] In some embodiments, the reduction mechanism 304 may include a speed reducer, such as a gear reducer, worm gear reducer, or planetary gear reducer. Figure 4 As shown, according to one embodiment of the roller brush device 3 of this utility model, the reduction mechanism 304 includes a planetary gear reducer. The input end of the planetary gear reducer is connected to the inner wall of the roller brush body 301, and the output end of the planetary gear reducer is connected to the transmission component 101 disposed within the roller brush body 301. When the rotating end cap assembly 302 rotates, it drives the roller brush body 301 to rotate. The rotation of the roller brush body 301 drives the planetary gear reducer to operate, and drives the transmission component 101 to rotate. In the above-mentioned transmission motion, the rotational speed of the transmission component 101 is reduced by the planetary gear reducer, and the torque of the transmission component 101 is increased, which is beneficial to improving the movement stability and cutting effect of the moving cutter 201.

[0047] In some implementations, refer to Figure 3 and Figure 4 As shown, the roller brush device 3 also includes a fixed end cap assembly 303, which is disposed at the other end of the roller brush body 301 and is used to connect the roller brush body 301 to an external device, such as the main unit of the cleaning device described below, so as to ensure that the roller brush body 301 can remain stable during rotation.

[0048] In some implementations, see Figure 4 As shown, the fixed end cap assembly 303 includes an end cap body and an end cap connector 3031 rotatably connected to the end cap body. The end cap body is installed at the other end of the roller brush body 301. One end of the end cap connector 3031 is rotatably connected to the end cap body, and the other end is fixedly connected to the host, thereby connecting the other end of the roller brush body 301 to the host.

[0049] In some implementations, see Figure 3 As shown, the roller brush device 3 also includes a cleaning component 305 disposed on the outer peripheral wall of the roller brush body 301. The cleaning component 305 can be used to clean the ground. For example, the cleaning component 305 includes a brush, which cleans the ground.

[0050] In some implementations, refer to Figure 3 As shown, a cutting gap is formed on the outer peripheral surface of the roller brush body 301. This cutting gap corresponds to the cutting unit 2. For example, the cutting gap corresponds to the moving cutter 201. In this way, during the operation of the roller brush device 3, hair can enter the roller brush body 301 through the cutting gap. The moving cutter 201 moves back and forth relative to the fixed cutter 202 to cut the hair, thereby preventing the hair from getting tangled in the roller brush device 3.

[0051] This utility model also provides a cleaning device, which includes a main unit and a roller brush device 3 disposed at the bottom of the main unit. The roller brush device 3 is used to clean the ground. In some embodiments, one end of the rotating end cap assembly 302 is drivenly connected to one end of the roller brush body 301, and the other end is drivenly connected to the drive unit of the main unit, such as an electric motor. The electric motor drives the rotating end cap assembly 302 to rotate, thereby driving the roller brush body 301 to rotate. A sweeping component 305 is provided on the outer peripheral surface of the roller brush body 301. The rotation of the roller brush body 301 drives the sweeping component 305 to rotate, thereby completing the cleaning of the ground.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
