Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a roller brush device and cleaning equipment. Background Technology

[0002] With the continuous development of cleaning equipment, many cleaning devices, such as sweepers, are equipped with cleaning roller brushes for cleaning floor debris. This design improves cleaning efficiency to a certain extent, making it easier to sweep up dust, debris, and other garbage.

[0003] However, these cleaning devices are prone to hair getting tangled in the cleaning rollers during use, especially in pet-owning households where pet hair sheds in large quantities. This hair easily gets tangled in the cleaning rollers, hindering their rotation. Not cleaning them regularly not only reduces the cleaning effectiveness of the device but may also shorten its lifespan due to untimely hair removal. Manually cleaning the hair tangled in the rollers is time-consuming and laborious, affecting the user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a roller brush device and cleaning equipment, which aims to solve the problem that hair is easily entangled on existing roller brushes, thus hindering the rotation of the roller brush.

[0005] To achieve the above objectives, the present invention provides a roller brush device, which includes:

[0006] A housing having a receiving cavity;

[0007] A roller brush assembly, detachably mounted in the receiving cavity, the roller brush assembly including a mounting base and a roller brush, one end of the roller brush being a mounting end rotatably connected to the mounting base, and the other end of the roller brush being a suspended end suspended within the receiving cavity, the mounting base being detachably connected to the housing; and

[0008] A locking mechanism is mounted on the housing and has a locked position fixed relative to the housing and an unlocked position movable relative to the housing.

[0009] When the locking mechanism is in the locked position, it confines the mounting base within the receiving cavity; when the locking mechanism is in the unlocked position, it releases the confinement of the mounting base.

[0010] In one embodiment of the present invention, the locking mechanism is rotatably connected to the inner wall of the receiving cavity. In the locked position, the locking mechanism is located on the outer periphery of the mounting base and abuts against the mounting base.

[0011] When the locking mechanism is in the unlocked position, the locking mechanism can rotate relative to the mounting base.

[0012] In one embodiment of this utility model, the rotation axis of the locking mechanism is parallel to the rotation axis of the roller brush. When the locking mechanism is in the unlocked position, the locking mechanism limits the mounting base in the axial direction of the roller brush.

[0013] In one embodiment of the present invention, the mounting base includes a base body and a mating member. The mating member is disposed on the peripheral side of the base body and protrudes from the peripheral side of the base body in the direction toward the inner wall of the receiving cavity. The roller brush is rotatably connected to one end face of the base body. The locking mechanism abuts against the mating member. When the locking mechanism is in the locked position, the locking mechanism limits the mating member along the axial direction of the roller brush.

[0014] In one embodiment of the present invention, the locking mechanism has an abutting surface that contacts the mating member, and the mating member has a mating surface that contacts the locking mechanism. At least one of the abutting surface and the mating surface is an inclined surface or an arc surface, and gradually approaches the roller brush along the direction from the mounting base to the roller brush.

[0015] In one embodiment of this utility model, the abutting surface includes a first abutting surface and a second abutting surface. The first abutting surface and the second abutting surface are connected sequentially along the rotation axis of the locking mechanism. Both the first abutting surface and the second abutting surface are inclined surfaces or arc surfaces. The first abutting surface gradually approaches the roller brush along the direction from the mounting base to the roller brush, and the second abutting surface gradually moves away from the roller brush along the direction from the mounting base to the roller brush.

[0016] When the mounting base is inserted into the receiving cavity, the mating member abuts against the second abutting surface and drives the locking mechanism to rotate. When the mounting base is removed from the receiving cavity, the mating member abuts against the first abutting surface and drives the locking mechanism to rotate. When the locking mechanism is in the locked position, the first abutting surface abuts against the mating member and limits the mating member along the axial direction of the brush roller.

[0017] In one embodiment of this utility model, the number of mating parts is two, and they are circumferentially spaced on the mounting base; the number of locking mechanisms corresponds to the number of mating parts.

[0018] In one embodiment of this utility model, the housing includes a lower shell and a roller brush cover. The roller brush cover is detachably connected to the lower shell and forms the receiving cavity together with the lower shell. When the roller brush cover is placed on the lower shell, the roller brush cover interacts with the locking mechanism to make the locking mechanism be in the locked position. When the roller brush cover is opened, the roller brush cover separates from the locking mechanism, and the locking mechanism switches to the unlocked position.

[0019] In one embodiment of this utility model, a fixing member is provided on the side of the roller brush cover facing the receiving cavity;

[0020] The fixing member is used to fix the locking mechanism when the roller brush cover is placed on the lower shell, so that the locking mechanism is in the locked position; when the roller brush cover is opened, the fixing member separates from the locking mechanism, and the locking mechanism switches to the unlocked position.

[0021] In one embodiment of this utility model, the fixing member is a fixing block protruding from the surface of the roller brush cover, and the surface of the locking mechanism is recessed to form a fixing groove. The fixing block is inserted into the fixing groove to restrict the rotation of the locking mechanism.

[0022] In one embodiment of this utility model, the fixing member is a fixing block protruding from the surface of the roller brush cover, and there is a rotation gap between the locking mechanism and the inner wall of the housing. The fixing block is inserted into the rotation gap to restrict the rotation of the locking mechanism.

[0023] In one embodiment of this utility model, the fixing member is made of a flexible material, and when the roller brush cover is placed on the lower shell, the fixing member and the locking mechanism are interference-fitted.

[0024] In one embodiment of the present invention, the inner wall of the receiving cavity is provided with a first radial positioning part, and the mounting seat is provided with a second radial positioning part. The first radial positioning part and the second radial positioning part cooperate to form a radial limit on the mounting seat.

[0025] In one embodiment of the present invention, the first radial positioning part is a locking block protruding from the inner wall of the receiving cavity, and the second radial positioning part is a locking groove formed on the peripheral side of the mounting seat. The locking block is embedded in the locking groove to achieve radial positioning of the mounting seat.

[0026] This utility model also proposes a cleaning device, which includes a dust collection device, a fan, and a roller brush device as described above. The dust collection device is connected to the receiving cavity, and the suction force generated by the fan is used to draw dust from the receiving cavity into the dust collection device.

[0027] The roller brush device proposed in this utility model includes a housing, a roller brush assembly, and a locking mechanism. The housing forms a receiving cavity, and the roller brush assembly includes a mounting base and a roller brush. One end of the roller brush is a mounting end and is rotatably connected to the mounting base, while the other end of the roller brush is a suspended end, suspended within the receiving cavity. The end of the mounting base opposite to the roller brush is detachably connected to the housing. Since hair generally tends to entangle at the rotating connection of the shaft, suspending the end of the roller brush away from the mounting base reduces hair entanglement on the roller brush assembly during floor cleaning. This improves the problem of hair entanglement hindering the rotation of the roller brush, thus enhancing the cleaning effect and service life of the cleaning equipment.

[0028] Furthermore, the locking mechanism in the roller brush assembly is mounted on the housing and has a locked position fixed relative to the housing and an unlocked position rotatable relative to the housing. When it is necessary to disassemble or install the roller brush assembly, the locking mechanism is switched to the unlocked position, at which point the locking mechanism can rotate relative to the housing, thus not limiting the mounting base. After the roller brush assembly is installed, the locking mechanism is switched to the locked position, at which point the locking mechanism confines the mounting base within the receiving cavity to fix the mounting base. Therefore, through the above solution, the convenience of disassembly and assembly of the roller brush assembly of this application, as well as the stability of the roller brush assembly during use, are improved.

[0041] This utility model proposes a roller brush device.

[0042] Combination Figures 1 to 3As shown, in one embodiment of this utility model, the roller brush device includes a housing 10, a roller brush assembly 20, and a locking mechanism 30. The housing 10 forms a receiving cavity 101, and the roller brush assembly 20 is detachably installed in the receiving cavity 101. The roller brush assembly 20 includes a mounting base 21 and a roller brush 22. One end of the roller brush 22 is a mounting end, which is rotatably connected to the mounting base 21. The other end of the roller brush 22 is a suspended end, which is suspended in the receiving cavity 101. The mounting base 21 is detachably connected to the housing 10. The locking mechanism 30 is installed on the housing 10 and has a locked position fixed relative to the housing 10 and an unlocked position movable relative to the housing 10. When the locking mechanism 30 is in the locked position, it restricts the mounting base 21 within the receiving cavity 101. When the locking mechanism 30 is in the unlocked position, it releases the restriction on the mounting base 21.

[0043] In this embodiment, the surface of the housing 10 has an opening communicating with the receiving cavity 101. When the roller brush assembly 20 is installed in the receiving cavity 101, the roller brush 22 can clean the surface to be cleaned through the opening. A rotating shaft is provided on the mounting end, and the mounting base 21 has a rotating hole; or the mounting end has a rotating hole, and the mounting base 21 has a rotating shaft. The roller brush 22 and the mounting base 21 are rotatably connected through the cooperation of the rotating shaft and the rotating hole. Since hair usually gets tangled at the rotating connection of the rotating shaft, suspending the other end of the roller brush 22 in the receiving cavity 101 can reduce the entanglement of hair between the roller brush 22 and the mounting base 21, and improve the problem of the roller brush 22 being obstructed from rotating due to hair entanglement on the roller brush assembly 20, thereby improving the cleaning effect and service life of the cleaning equipment. The mounting base 21 and the housing 10 can be detachably connected by means of plug-in, snap-fit, or threaded connection.

[0044] The locking mechanism 30 and the housing 10 can be rotatably connected or movably connected. The locking mechanism 30 can be disposed within the receiving cavity 101, or partially located within and partially located outside the receiving cavity 101. Specifically, regarding the switching between the locked and unlocked positions of the locking mechanism 30, at least the following implementation schemes are included:

[0045] The housing 10 can be configured to include a lower housing 11 and a brush cover 12. The locking mechanism 30 is disposed in the receiving cavity 101 and rotatably connected to the lower housing 11. When the brush cover 12 is placed on the lower housing 11, the brush cover 12 presses against the locking mechanism 30 to restrict the rotation of the locking mechanism 30, so that the locking mechanism 30 is in the locked position. When the brush cover 12 is opened, the brush cover 12 is separated from the locking mechanism 30. At this time, the locking mechanism 30 can rotate relative to the housing 10, so that the locking mechanism 30 is in the unlocked position.

[0046] Alternatively, the locking mechanism 30 can be configured to include a rotating member and a fixed member. The rotating member is disposed within the receiving cavity 101 and rotatably connected to the housing 10. The fixed member is disposed outside the receiving cavity 101 and can move toward the rotating member. The fixed member can include structures such as pins, bolts, and friction blocks. In this case, the fixed member functions like a switch. By moving the fixed member, it comes into contact with the rotating member, restricting the rotation of the rotating member. By moving the fixed member in the opposite direction, it separates from the rotating member, allowing the rotating member to rotate freely. For example, when the fixed member is a friction block, by moving the friction block, it comes into contact with the rotating member, and the friction between the friction block and the rotating member restricts the rotation of the rotating member, thereby placing the locking mechanism 30 in the locked position. When the friction block is moved in the opposite direction, it separates from the rotating member, allowing the rotating member to rotate freely.

[0047] The locking mechanism 30 can also be movably connected to the housing 10, and the locking mechanism 30 can move toward or away from the roller brush assembly 20. When the locking mechanism 30 moves to press against the mounting end, the contact force between the locking mechanism 30 and the mounting end restricts the movement of the mounting end, thereby confining the mounting seat 21 within the receiving cavity 101. When the locking mechanism 30 moves to separate from the mounting end, the locking mechanism 30 releases its restriction on the mounting end.

[0048] This application incorporates a locking mechanism 30. When the roller brush assembly 20 needs to be disassembled or installed, the locking mechanism 30 is switched to the unlocked position. In this position, the locking mechanism 30 can move relative to the housing 10, thus not limiting the mounting base 21. After the roller brush assembly 20 is installed, the locking mechanism 30 is switched to the locked position. In this position, the locking mechanism 30 confines the mounting base 21 within the receiving cavity 101, thereby fixing the mounting base 21. Therefore, this solution improves the ease of disassembly and assembly of the roller brush assembly 20, as well as its stability during use.

[0049] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the locking mechanism 30 is rotatably connected to the inner wall of the receiving cavity 101. In the locked position, the locking mechanism is located on the outer periphery of the mounting base 21 and abuts against the mounting base 21. When the locking mechanism 30 is in the unlocked position, the locking mechanism 30 can rotate relative to the mounting base 21.

[0050] Specifically, the rotation axis of the locking mechanism 30 can be parallel to the rotation axis of the roller brush 22, perpendicular to the rotation axis of the roller brush 22, or form an acute angle with the rotation axis of the roller brush 22. When the locking mechanism 30 is in the locked position, it abuts against the mounting base 21 and remains relatively fixed to the housing 10, thus limiting the mounting base 21. When the locking mechanism 30 is in the unlocked position, it can rotate relative to the mounting base 21 to release the limitation on the mounting base 21.

[0051] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the rotation axis of the locking mechanism 30 is parallel to the rotation axis of the roller brush 22; when the locking mechanism 30 is in the locked position, the locking mechanism 30 limits the mounting base 21 in the axial direction of the roller brush 22.

[0052] In this embodiment, the locking mechanism 30 is disposed within the receiving cavity 101 and located on the outer periphery of the mounting base 21. The rotation axis of the locking mechanism 30 is set parallel to the rotation axis of the roller brush 22, allowing the locking mechanism 30 to move closer to or further away from the mounting base 21 during rotation. The locking mechanism 30 can be directly mounted on the inner wall of the receiving cavity 101 via a rotating shaft, or it can be mounted within a rotating channel provided within the housing 10. For details regarding the connection method between the locking mechanism 30 and the housing 10, please refer to the following:

[0053] In one embodiment, the inner wall of the receiving cavity 101 is provided with a rotating hole, and the surface of the locking mechanism 30 is provided with a through rotating shaft hole. The rotating shaft passes through the rotating shaft hole and is rotatably disposed in the rotating hole to realize the rotatable connection between the locking mechanism 30 and the housing 10.

[0054] In another embodiment, the cavity wall of the receiving cavity 101 is provided with a mounting block 111, which forms a rotating channel. Rotating holes are formed on opposite side walls of the rotating channel. A through-hole is formed on the surface of the locking mechanism 30, through which a rotating shaft passes. The shaft is rotatably disposed in the two rotating holes at both ends, so that the locking mechanism 30 is rotatably mounted within the rotating channel. One end of the locking mechanism 30 extends out of the rotating channel and abuts against the end of the mating member 212.

[0055] Since one end of the roller brush 22 is suspended within the receiving cavity 101, this application uses a locking mechanism 30 to limit the mounting base 21 along the axial direction of the roller brush 22. It can be understood that the axial direction of the roller brush 22 refers to the axial direction after the roller brush 22 is installed within the receiving cavity 101, that is, the direction corresponding to... Figure 1 In the established three-dimensional coordinate system, along a direction parallel to the X-axis. For ease of understanding, in the following text of this application, it will be referred to as... Figure 1The established three-dimensional coordinate system serves as a reference to describe the installation direction or movement direction of each component of the roller brush device.

[0056] Since the locking mechanism 30 can move away from the mounting base 21 when in the unlocked position, when the roller brush assembly 20 needs to be installed, switching the locking mechanism 30 to the unlocked position allows the roller brush assembly 20 to be installed in the receiving cavity 101 along the X-axis or at an acute angle to the X-axis (i.e., obliquely). When the roller brush assembly 20 needs to be removed, it can also be taken out of the receiving cavity 101 along the X-axis or at an acute angle to the X-axis (i.e., obliquely).

[0057] Of course, in other embodiments, the locking mechanism 30 can also be configured to limit the mounting base 21 radially along the roller brush 22, that is, to limit the mounting base 21 radially along the roller brush 22. Figure 1 Limiting in the Y-axis or Z-axis direction. At this time, another connection structure needs to be set between the mounting base 21 and the housing 10, and limit the mounting base 21 in the upward (i.e., X-axis) direction along the roller brush 22 axis, so that the roller brush assembly 20 is stably held in the receiving cavity 101.

[0058] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the mounting base 21 includes a base body 211 and a mating member 212. The mating member 212 is disposed on the peripheral side of the base body 211 and protrudes from the peripheral side of the base body 211 in the direction toward the inner wall of the receiving cavity 101. The roller brush 22 is rotatably connected to one end face of the base body 211. The locking mechanism 30 abuts against the mating member 212. When the locking mechanism 30 is in the locked position, the locking mechanism 30 limits the mating member 212 along the axial direction of the roller brush 22.

[0059] In this embodiment, the mating component 212 can be a bracket structure, a protrusion structure, etc. The mating component 212 can protrude from the peripheral side of the seat body 211 along the radial direction of the roller brush 22, or it can protrude at an acute angle relative to the radial direction of the roller brush 22, such as 30 degrees, 45 degrees, or 60 degrees. When the roller brush assembly 20 is installed in the receiving cavity 101, the mating component 212 abuts against the locking mechanism 30, driving the locking mechanism 30 to rotate. After the roller brush assembly 20 is installed, the limiting structure between the locking mechanism 30 and the mating component 212 includes the following implementation:

[0060] The locking mechanism 30 is located on the side of the mating part 212 facing the roller brush 22. When the locking mechanism 30 is switched to the locked position, the locking mechanism 30 forms a locking action on the mating part 212 along... Figure 1 Limitation in the X-axis direction.

[0061] Alternatively, the locking mechanism 30 is located in the extending direction of the mating member 212 and abuts against the end of the mating member 212. When the locking mechanism 30 is switched to the locked position, the locking mechanism 30 can also form a locking action along the mating member 212. Figure 1 Limitation in the X-axis direction.

[0062] Combination Figure 3 and Figure 5 As shown, in one embodiment of the present invention, the locking mechanism 30 has an abutting surface that contacts the mating member 212, and the mating member 212 has a mating surface that contacts the locking mechanism 30. At least one of the abutting surface and the mating surface is an inclined surface or an arc surface, and gradually approaches the roller brush 22 along the direction from the mounting base 21 to the roller brush 22.

[0063] In this embodiment, the force between the locking mechanism 30 and the mating member 212 is perpendicular to their contact surface. Therefore, when at least one of the abutment surface and the mating surface is an inclined surface or an arc surface, the force between the locking mechanism 30 and the mating member 212 is perpendicular to their contact surface. Figure 1 In the direction that is at an acute angle relative to the X-axis, the force has a component force along the radial direction of the brush 22.

[0064] Therefore, when the locking mechanism 30 is in the unlocked position, when the roller brush assembly 20 is pulled along the X-axis or at an angle, the mating part 212 can drive the locking mechanism 30 to rotate under the action of the inclined or curved surface, so that the locking mechanism 30 moves away from the mounting base 21, so that the roller brush assembly 20 can be smoothly removed from the receiving cavity 101. When it is necessary to install the roller brush assembly 20, the locking mechanism 30 can be manually rotated away from the mounting base 21 to create a clearance space between the locking mechanism 30 and the mating part 212, and then the roller brush assembly 20 can be installed into the receiving cavity 101.

[0065] When the locking mechanism 30 is in the locked position, the locking mechanism 30 abuts against the mating part 212. Under the action of the inclined or arc surface, the locking mechanism 30 forms a double limit on the mating part 212 along the axial and radial directions of the roller brush 22, thereby improving the stability of the roller brush assembly 20 and reducing the need for additional connecting parts to fix the roller brush assembly 20.

[0066] Combination Figure 5 As shown, in one embodiment of the present invention, the contact surface includes a first contact surface 31 and a second contact surface 32. The first contact surface 31 and the second contact surface 32 are connected sequentially along the rotation axis of the locking mechanism 30. Both the first contact surface 31 and the second contact surface 32 are inclined surfaces or arc surfaces. The first contact surface 31 gradually approaches the roller brush 22 along the direction from the mounting base 21 to the roller brush 22, and the second contact surface 32 gradually moves away from the roller brush 22 along the direction from the mounting base 21 to the roller brush 22.

[0067] When the mounting base 21 is inserted into the receiving cavity 101, the mating part 212 abuts against the second abutting surface 32 and drives the locking mechanism 30 to rotate. When the mounting base 21 is removed from the receiving cavity 101, the mating part 212 abuts against the first abutting surface 31 and drives the locking mechanism 30 to rotate. When the locking mechanism 30 is in the locked position, the first abutting surface 31 abuts against the mating part 212 and forms a radial limit on the mating part 212.

[0068] In this embodiment, the design of the first abutment surface 31 improves the ease of removing the roller brush assembly 20 from the receiving cavity 101. The second abutment surface 32 improves the ease of installing the roller brush assembly 20 into the receiving cavity 101.

[0069] Specifically, when it is necessary to remove the roller brush assembly 20 from the receiving cavity 101, the roller brush assembly 20 is pulled out along the X-axis or at an angle. At this time, the mating part 212 abuts against the first abutting surface 31 and drives the locking mechanism 30 to rotate so that the locking mechanism 30 gradually moves away from the mounting base 21.

[0070] When the roller brush assembly 20 needs to be installed, it is inserted into the receiving cavity 101 along the X-axis or at an angle. At this time, the mating part 212 first abuts against the second abutting surface 32, driving the locking mechanism 30 to rotate, so that the locking mechanism 30 gradually moves away from the mounting base 21. Then, the mating part 212 moves to abut against the first abutting surface 31. At this time, the locking mechanism 30 moves towards the mounting base 21 under the action of gravity or external driving force. The connection between the first abutting surface 31 and the second abutting surface 32 is smoothly transitioned to improve the smoothness of the movement of the mating part 212.

[0071] After the roller brush assembly 20 is installed in place, the mating part 212 abuts against the first abutting surface 31, and the first abutting surface 31 forms a double limit on the mating part 212 in the axial and radial directions along the roller brush 22.

[0072] In the above process, by setting the first contact surface 31 and the second contact surface 32, the locking mechanism 30 can be driven to rotate by the mating part 212 during the assembly and disassembly of the roller brush assembly 20, without the need for external driving force to drive the locking mechanism 30 to rotate, thereby improving the convenience of assembly and disassembly of the roller brush assembly 20.

[0073] Combination Figures 2 to 4 As shown, in one embodiment of this utility model, there are two mating parts 212, which are circumferentially spaced on the mounting base 21. The number of locking mechanisms 30 corresponds to the number of mating parts 212, and each locking mechanism 30 is mated with one mating part 212.

[0074] In this embodiment, the two mating parts 212 can be symmetrically arranged on both sides of the mounting base 21, or they can be arranged asymmetrically. Each locking mechanism 30 corresponds to one mating part 212. The specific structure of the locking mechanism 30 and the mating part 212 can be referred to the description of the above embodiment, and will not be elaborated further here. As can be seen from the above embodiment, the locking mechanism 30 provides a radial limit for the mating part 212 along the roller brush 22. Therefore, by setting two sets of mating parts 212 and locking mechanism 30, the stability of the mounting base 21 can be further improved.

[0075] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, the housing 10 includes a lower housing 11 and a roller brush cover 12. The roller brush cover 12 is detachably connected to the lower housing 11 and forms a receiving cavity 101 with the lower housing 11. When the roller brush cover 12 is placed on the lower housing 11, the roller brush cover 12 interacts with the locking mechanism 30 to make the locking mechanism 30 be in the locked position. When the roller brush cover 12 is opened, the roller brush cover 12 is separated from the locking mechanism 30, and the locking mechanism 30 is switched to the unlocked position.

[0076] In this embodiment, the roller brush cover 12 and the lower shell 11 can be detachably connected by means of rotational connection, snap-fit, threaded connection, etc. In one embodiment, the roller brush cover 12 and the lower shell 11 are rotatably connected. A rotation hole or rotation shaft is provided on one side of the lower shell 11, and a rotation shaft or rotation hole is provided on one side of the roller brush cover 12. The rotational connection between the roller brush cover 12 and the lower shell 11 is realized through the cooperation between the rotation shaft and the rotation hole.

[0077] When the roller brush cover 12 is placed on the lower housing 11, the roller brush cover 12 interacts with the locking mechanism 30. For example, the roller brush cover 12 can be pressed against the locking mechanism 30, and the surface of the roller brush cover 12 in contact with the locking mechanism 30 can be a plane. Alternatively, a fixing member can be provided on the surface of the roller brush cover 12 facing the locking mechanism 30, and the fixing member can be pressed against the locking mechanism 30 to fix the locking mechanism 30. Therefore, during the disassembly and assembly of the roller brush assembly 20, opening the roller brush cover 12 can unlock the locking mechanism 30, at which point the roller brush assembly 20 can be taken out from the receiving cavity 101. The cooperation and movement relationship between the roller brush assembly 20 and the locking mechanism 30 during the removal process can be referred to the description of the above embodiment, and will not be further elaborated here. When installing the roller brush assembly 20, insert the roller brush assembly 20 into the receiving cavity 101, and then close the roller brush cover 12. At this time, under the fixing action of the roller brush cover 12, the locking mechanism 30 is in the locked position and abuts against the mounting base 21, thereby fixing the roller brush assembly 20.

[0078] Therefore, it can be seen that during the entire disassembly and assembly of the roller brush assembly 20, simply opening or closing the roller brush cover 12 is sufficient to unlock or lock the locking mechanism 30, thus improving the convenience of disassembly and assembly of the roller brush assembly 20.

[0079] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, a fixing member is provided on the side of the roller brush cover 12 facing the receiving cavity 101; the fixing member is used to fix the locking mechanism 30 when the roller brush cover 12 is placed on the lower shell 11 so that the locking mechanism 30 is in the locked position; when the roller brush cover 12 is opened, the fixing member is separated from the locking mechanism 30, and the locking mechanism 30 is switched to the unlocked position.

[0080] In this embodiment, the fixing member can be a protrusion on the surface of the brush cover 12, a groove on the surface of the brush cover 12, or a flexible structure on the surface of the brush cover 12. When the brush cover 12 is fastened to the lower shell 11, the fixing member abuts against and is fixed to the locking mechanism 30, so that the locking mechanism 30 is in the locked position. When the brush cover 12 is opened, the fixing member separates from the locking mechanism 30, at which time the locking mechanism 30 can rotate freely.

[0081] Combination Figure 3 As shown, in one embodiment of the present invention, the fixing member is a fixing block 121 protruding from the surface of the roller brush cover 12, and the surface of the locking mechanism 30 is recessed to form a fixing groove. The fixing block 121 is inserted into the fixing groove to restrict the rotation of the locking mechanism 30.

[0082] In this embodiment, the shape and size of the fixing groove and the fixing block 121 are adapted to each other, specifically they can be spherical, elliptical, frustum-shaped, etc. The fixing groove and the fixing block 121 are positioned correspondingly. When the roller brush cover 12 is fastened to the lower shell 11, the fixing block 121 is embedded in the fixing groove. At this time, one end of the locking mechanism 30 is pressed by the fixing block 121, and the other end is pressed by the mating part 212 of the mounting base 21, thereby keeping the locking mechanism 30 relatively fixed so that it is stably in the locked position.

[0083] Of course, in other embodiments, a fixing block 121 can be protruded on the surface of the locking mechanism 30, and a fixing groove can be formed by recessing on the surface of the roller brush cover 12.

[0084] Combination Figure 3 As shown, in one embodiment of this utility model, the fixing member is a fixing block 121 protruding from the surface of the roller brush cover 12, and there is a rotation gap 15 between the locking mechanism 30 and the inner wall of the housing 10. The fixing block 121 is inserted into the rotation gap 15 to restrict the rotation of the locking mechanism 30.

[0085] In this embodiment, since the locking mechanism 30 rotates relative to the housing 10, after the fixing block 121 is inserted into the rotation gap 15 between the locking mechanism 30 and the housing 10, the fixing block 121 can prevent the locking mechanism 30 from continuing to rotate. The fixing block 121 is adapted to the rotation gap 15, or when the fixing block 121 is inserted into the rotation gap 15, its two sides abut against the locking mechanism 30 and the housing 10 respectively.

[0086] As mentioned above, the cavity wall of the receiving cavity 101 is provided with a mounting block 111, which forms a rotation channel. The locking mechanism 30 is rotatably disposed within the rotation channel. During the rotation of the locking mechanism 30 driven by the mounting base 21, the gap between the locking mechanism 30 and one side of the rotation channel gradually decreases. Therefore, in one embodiment, the fixing block 121 is disposed within the rotation gap 15 that gradually decreases as the locking mechanism 30 rotates, in order to further improve the stopping effect on the locking mechanism 30.

[0087] In one embodiment of this utility model, the fixing member is made of a flexible material. When the roller brush cover 12 is placed on the lower shell 11, the fixing member and the locking mechanism 30 are interference-fitted. Specifically, the fixing member can be made of flexible materials such as rubber or silicone. When the roller brush cover 12 is placed on the lower shell 11, the fixing member is deformed by the compression of the locking mechanism 30 and is interference-fitted with the locking mechanism 30 so that the locking mechanism 30 is in the locked position.

[0088] In one embodiment of the present invention, the inner wall of the receiving cavity 101 is provided with a first radial positioning part, and the mounting base 21 is provided with a second radial positioning part. The first radial positioning part and the second radial positioning part cooperate to form a radial limit on the mounting base 21.

[0089] In this embodiment, the first radial positioning part and the second radial positioning part can be a snap-fit, a magnetic fit, an interference fit, etc. For example, when the first radial positioning part and the second radial positioning part are snap-fit, one of the first radial positioning part and the second radial positioning part can be a locking block, an arc-shaped protrusion, a slot, etc., and the other can be a matching slot, an arc-shaped concave surface, a locking block, etc.

[0090] When the first radial positioning part and the second radial positioning part are magnetically engaged, one of the first radial positioning part and the second radial positioning part is a magnetic component (e.g., a magnet), and the other is a component that can be attracted by magnetism (e.g., ferromagnetic materials such as iron, cobalt, and nickel).

[0091] When the first radial positioning part and the second radial positioning part are interference fit, one of the first radial positioning part and the second radial positioning part has a mating groove, and the other has a mating body. At least one of them is elastic, so that the mating body is embedded in the mating groove to form an interference fit structure.

[0092] By providing a first radial positioning part and a second radial positioning part, after the roller brush assembly 20 is installed in the receiving cavity 101, the housing 10 can limit the roller brush assembly 20 in the radial direction of the roller brush 22, thereby improving the stability of the roller brush assembly 20.

[0093] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the first radial positioning part is a locking block 13 protruding from the inner wall of the receiving cavity 101, and the second radial positioning part is a locking groove 211a formed on the peripheral side of the mounting base 21. The locking block 13 is embedded in the locking groove 211a to achieve radial positioning of the mounting base 21.

[0094] In this embodiment, the shape of the locking block 13 is adapted to the shape of the locking groove 211a, which is located at the end of the mounting base 21 away from the roller brush 22 and on the side of the mounting base 21 facing the roller brush cover 12. Therefore, when the roller brush assembly 20 is installed into the receiving cavity 101, the locking block 13 is embedded in the locking groove 211a, and the locking block 13 can limit the roller brush 22 radially. As can be seen from the above, the locking mechanism 30 can limit the mounting base 21 axially along the roller brush 22. Therefore, the design of this application enables the roller brush assembly 20 to be stably held in the receiving cavity 101. In addition, during the entire disassembly and assembly process of the roller brush assembly 20, it is only necessary to pull and insert to remove and fix the roller brush assembly 20, which simplifies the structure and improves the convenience of disassembly and assembly.

[0095] This utility model also proposes a cleaning device, which includes a roller brush device, a dust collection device, and a fan. The specific structure of the roller brush device is as described in the above embodiments. Since this cleaning device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0096] This cleaning equipment can be a robotic vacuum cleaner, a robotic sweeper and mop, a handheld vacuum cleaner, a handheld floor scrubber, etc. Through the aforementioned improvements to the roller brush device, the cleaning equipment reduces hair entanglement during floor cleaning, improving cleaning efficiency and lifespan. It also simplifies the structure of the cleaning equipment and improves the convenience of assembling and disassembling the roller brush assembly 20. Specifically, the housing 10 has a suction port located near the suspended end. During the rotation of the roller brush 22, dust and hair are moved to the vicinity of the suction port by the suction force of the fan. Positioning the suction port at the suspended end further reduces the entanglement of hair and dust at the rotating shaft. The dust collection device includes a dust collection box and a filter. When dust-laden air is drawn in by the fan, it first passes through the dust collection box. The filter inside the dust collection box filters out dust and debris, retaining them within the dust collection box.

[0097] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
