Description

Technical Field

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

[0002] A floor scrubber is a device used for cleaning floors, widely used in homes, commercial spaces, and industrial areas. It combines vacuuming, mopping, and wastewater collection functions, efficiently cleaning hard surfaces such as tile, wood flooring, and marble. A floor scrubber mainly consists of a roller brush assembly, the main body, and, mounted on the body, a clean water tank, a wastewater tank, and a battery.

[0003] The roller brush assembly of a floor scrubber typically includes a roller brush body and a handle. In existing roller brush assemblies, the roller brush body and the handle are fixedly connected and cannot be disassembled. When the roller brush body is worn or damaged and needs to be replaced, the handle must be replaced along with the roller brush body, resulting in resource waste and high replacement costs. Utility Model Content

[0004] Based on the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide a roller brush assembly, including a roller brush and a handle. The handle is equipped with a mounting component, which engages with the rotating part of the roller brush via a locking pin, allowing the handle to be quickly attached and detached from the roller brush. This makes operation convenient, requires minimal structural modifications to the roller brush assembly, and reduces manufacturing costs. The handle of this solution can be used on any roller brush with mounting holes, making it widely applicable.

[0005] Therefore, the present invention provides the following technical solution.

[0006] This utility model provides a roller brush assembly, the roller brush assembly comprising:

[0007] A roller brush, comprising a mounting base, the mounting base having a rotating component, the rotating component having a mounting hole;

[0008] A handle, comprising a handle and a mounting assembly, the mounting assembly including a locking pin that can be inserted into the mounting hole so that the roller brush, in relation to the handle, can rotate relative to it.

[0009] The locking pin can be switched between a first position and a second position;

[0010] When the locking pin is in the first position, the locking pin is in a restrictive engagement with the rotating component. The restrictive engagement means that when the handle is installed in the target installation position, the locking pin is inserted into the mounting hole and restricts the handle from detaching from the mounting base.

[0011] When the handle needs to be disassembled or assembled, the locking pin is switched to the second position so that the handle can be disengaged from the mounting hole.

[0012] In existing technologies, cleaning equipment, including but not limited to manual or automatic cleaning devices such as floor scrubbers and mops, is used frequently. During the cleaning process, the roller brush directly contacts the surface to be cleaned, cleaning the floor through high-speed rotation, scrubbing, and vacuuming. After a period of use, the roller brush will wear out, become damaged, and the bristles will deform. To ensure cleaning effectiveness, the roller brush needs to be replaced in a timely manner. To facilitate handling, the roller brush is equipped with a handle. In existing cleaning equipment, the roller brush and handle are usually assembled using screws, rivets, or other fixing methods. The handle is not easy to disassemble, and when the roller brush needs to be replaced, the handle is replaced along with the roller brush, resulting in resource waste and high replacement costs.

[0013] Based on this, the roller brush assembly of this application includes a roller brush and a handle. The handle is equipped with a mounting component, which engages with the rotating part of the roller brush via a locking pin. By changing the position of the locking pin, the handle can switch between two states: being restricted from detaching from the mounting base and being detachable from the mounting base. This allows the handle to be quickly attached to and detached from the roller brush, making operation convenient. This solution requires minimal modification to the roller brush structure, reducing manufacturing costs. The handle of this solution can be used on any roller brush with mounting holes, making it widely applicable.

[0014] Secondly, this solution places the rotating component inside the roller brush, rather than placing it on the handle. One can imagine placing the rotating component on the handle and then connecting the roller brush to the handle, which would also allow the roller brush to rotate through the rotating component.

[0015] However, placing it on the handle can cause instability. Specifically, the handle is too small to install properly, and the handle itself has a columnar structure, making the end with the rotating part heavier, resulting in a structure that is heavy at one end and light at the other.

[0016] Furthermore, users typically hold one end of the handle while disassembling the device, which causes stress to concentrate at the rotating part. This can lead to instability and deviation of the rotating part after prolonged use. However, placing the rotating part on the roller brush provides greater stability because the roller brush has a larger installation area and the rotating part is located inside the roller brush and is enclosed and restricted.

[0017] Optionally, the mounting assembly further includes a locking member and a locking sleeve, wherein the circumferential surface wall of the locking pin is provided with a groove and an abutment portion, the locking sleeve is sleeved on the locking pin and is provided with a through hole, and the locking member is movably inserted into the through hole;

[0018] When the locking pin is in the first position and the handle is installed in the target installation position, the locking sleeve is inserted into the mounting hole, and the locking member extends partially out of the through hole under the abutment of the abutment portion, so that the locking member abuts against the rotating member in the disengagement direction of the handle to achieve the limiting fit.

[0019] When the locking pin is switched to the second position, the groove can at least partially receive the locking member so that the locking member retracts into the through hole, thereby allowing the locking sleeve and the locking member to pass through the mounting hole.

[0020] The above solution utilizes a locking pin, locking element, and locking sleeve to facilitate quick and easy attachment and removal of the handle from the roller brush. The locking pin adjusts the position of the locking element within the through-hole of the locking sleeve by changing its position, allowing the locking element to switch between locked and unlocked positions. Furthermore, when in the locked position, the locking element abuts against the mounting base along the handle's disengagement direction, preventing the locking sleeve from disengaging from the mounting base in the same direction. This design requires minimal modification to the roller brush structure, reducing manufacturing costs. The handle in this solution is compatible with any roller brush equipped with mounting holes, making it widely applicable.

[0021] Optionally, when the handle needs to be installed, the locking pin is switched to the second position, and during the process of the locking sleeve being inserted into the mounting hole in the first direction, the locking member can pass through the mounting hole in the first direction.

[0022] When the handle reaches the target installation position, the locking pin is switched to the first position so that the locking member abuts against the rotating member in the second direction to prevent the locking sleeve from disengaging from the roller brush in the second direction;

[0023] When the handle needs to be removed, the locking pin is switched to the second position so that the locking member can pass through the mounting hole in the second direction, thereby allowing the locking sleeve to disengage from the roller brush in the second direction.

[0024] The first direction is opposite to the second direction.

[0025] In the above scheme, the mounting components, through the cooperation of locking pins, locking parts, and locking sleeves, enable the handle to be smoothly and quickly installed on the mounting base of the roller brush in the first direction, or to be detached from the mounting base of the roller brush in the second direction.

[0026] Optionally, the mounting component may further include a limiting structure;

[0027] When the handle is in the target installation position, the limiting structure abuts against the mounting base along the installation direction of the handle, so that the handle is locked to the roller brush.

[0028] In the above solution, the limiting structure and the locking component clamp the mounting base in opposite directions, thereby limiting the displacement of the handle relative to the roller brush in the installation or disengagement direction, and thus locking the handle to the roller brush.

[0029] Optionally, the limiting structure is disposed on the outer wall of the locking sleeve; and / or, the limiting structure is a protruding structure.

[0030] The above solution, by placing the limiting structure on the outer wall of the locking sleeve, achieves the goal of abutting the limiting structure against the mounting base while meeting the requirement of miniaturized design. The limiting structure is designed as a protrusion, resulting in a simple structure that is easy to manufacture.

[0031] Optionally, the rotating component is configured as a bearing, the mounting base includes a base body, the rotating component is mounted on the base body, and the inner ring of the rotating component forms the mounting hole;

[0032] When the handle is in the target installation position, the locking member abuts against the inner ring of the rotating member along the disengagement direction of the handle to prevent the locking sleeve from disengaging from the roller brush;

[0033] The above solution assembles the handle using a rotating component, so that the roller brush can rotate independently of the handle during operation, and the handle does not rotate with the roller brush.

[0034] And / or, the locking element is spherical; in this solution, the locking element has a simple structure and facilitates the smooth insertion or removal of the locking element from the groove of the locking pin;

[0035] And / or, when the locking pin is in the first position, the groove is away from the first groove wall of the handle and extends obliquely toward the locking member in the installation direction of the handle; in this solution, the shape of the first groove wall is defined, which is conducive to the locking member switching quickly and smoothly between the locked position and the unlocked position, and avoids the locking member getting stuck.

[0036] And / or, the groove is annular; in this solution, the shape of the groove is limited, which can reduce the accuracy requirements for the assembly of the locking pin and the locking component when assembling and installing the components, and reduce the assembly difficulty.

[0037] Optionally, the mounting assembly further includes an elastic element, one end of which abuts against the locking sleeve along the mounting direction of the handle, and the other end of which is linked with the locking pin;

[0038] During the process of the locking pin moving from the first position to the second position, the locking pin compresses the elastic element;

[0039] As the locking pin moves from the second position to the first position, the elastic element rebounds to provide power for the locking pin to reset.

[0040] The above solution uses an elastic element to provide power for the locking pin to reset, enabling the locking pin to reset automatically and making operation convenient.

[0041] Optionally, the mounting assembly further includes a button movably connected to the handle, the button being fixed to the locking pin, and the other end of the elastic element abutting against the button;

[0042] When the button is pressed by an external force, the button causes the locking pin to move from the first position to the second position;

[0043] When the external force is removed, the elastic element rebounds, causing the button to move the locking pin from the second position to the first position.

[0044] The above solution, in terms of button design, on the one hand, avoids the locking pin being directly exposed, improving the aesthetics of the handle; on the other hand, by increasing the size of the button, it can increase the pressable contact area, making it easier to operate.

[0045] Optionally, the mounting assembly further includes a mounting element having a mounting channel and a mounting plate, wherein the handle is mounted on the mounting plate;

[0046] One end of the locking sleeve is installed in the mounting channel, and the through hole is located on the outside of the mounting component.

[0047] The above solution indirectly connects the handle and the locking sleeve through the mounting component. Compared with the solution that directly connects the handle and the locking sleeve, this reduces the structural complexity of the handle and the processing cost of the handle.

[0048] Optionally, the mounting base has a recess on the side facing the handle;

[0049] When the handle is in the target installation position, the mounting assembly is at least partially embedded in the cavity, and the mounting plate covers the open end of the cavity.

[0050] The above design avoids the handle protruding excessively from the roller brush, which helps to reduce the overall size of the roller brush assembly and improve its aesthetic appearance. Furthermore, the mounting plate covers the open end of the recessed cavity to improve the appearance of the assembly between the roller brush and the handle, and to prevent dust and other debris from entering the cavity and causing cleaning difficulties.

[0051] This utility model also provides a cleaning device, which includes the roller brush assembly described above.

[0052] This utility model has the following technical effects:

[0053] This utility model provides a roller brush assembly, including a roller brush and a handle. The handle is equipped with a mounting component, which engages with the rotating part of the roller brush via a locking pin. By changing the position of the locking pin, the handle can switch between two states: being restricted from detaching from the mounting base and being detachable from the mounting base. This allows the handle to be quickly attached to and detached from the roller brush, making operation convenient. This solution involves minimal structural modifications to the roller brush assembly, reducing manufacturing costs. The handle of this solution can be used on any roller brush with mounting holes, making it widely applicable. Attached Figure Description

[0077] In this utility model, "first direction a" and "second direction b" refer to... Figure 1 and Figure 2 The markings in the text shall prevail.

[0078] The following is based on Figures 1 to 9 This invention provides a detailed description of the cleaning equipment.

[0079] In this embodiment, the cleaning equipment includes a body (not shown in the figure) and a roller brush assembly 100. A controller is provided in the body to control the operation of the roller brush assembly 100. Figures 1 to 9 As shown, the roller brush assembly 100 includes a roller brush 1 and a handle 2. The roller brush 1 includes a mounting base 11, a cylinder 12, and a cleaning component 13. The mounting base 11 is mounted on the cylinder 12. The cleaning component 13 (such as brush bristles) covers the cylinder 12 circumferentially. The cylinder 12 is also detachably connected to the main body. The inner wall of the cylinder 12 is provided with a transmission part 121, which is used to transmit the rotational driving force of the motor to the cylinder 12 so that the cylinder 12 rotates. The mounting base 11 is provided with a rotating component 113, which has a mounting hole 111. The handle 2 includes a handle 21 and a mounting component 22. The handle 21 is for the operator to hold. The mounting component 22 includes a locking pin 221, which can be inserted into the mounting hole 111 so that the roller brush 1 can rotate relative to the handle 2. That is, during the operation of the roller brush 1, it can rotate independently of the handle 2. In other words, the handle 2 does not rotate with the roller brush 1.

[0080] Locking pin 221 can switch between a first position and a second position. When locking pin 221 is in the first position, it engages with rotating component 113. This engagement means that when handle 2 is installed in the target mounting position, locking pin 221 is inserted into mounting hole 111, preventing handle 2 from detaching from mounting base 11, thus ensuring stable mounting of handle 2 to roller brush 1. When handle 2 needs to be removed, locking pin 221 is switched to the second position. At this time, locking pin 221 releases its engagement with rotating component 113, allowing handle 2 to detach from mounting hole 111. When roller brush 1 needs to be replaced, handle 2 can be removed from roller brush 1.

[0081] In existing technologies, cleaning equipment, including but not limited to manual or automatic cleaning devices such as floor scrubbers and mops, is used frequently. During the cleaning process, the roller brush directly contacts the surface to be cleaned, cleaning the floor through high-speed rotation, scrubbing, and vacuuming. After a period of use, the roller brush will wear out, become damaged, and the bristles will deform. To ensure cleaning effectiveness, the roller brush needs to be replaced in a timely manner. To facilitate handling, the roller brush is equipped with a handle. In existing cleaning equipment, the roller brush and handle are usually assembled using screws, rivets, or other fixing methods. The handle is not easy to disassemble, and when the roller brush needs to be replaced, the handle is replaced along with the roller brush, resulting in resource waste and high replacement costs.

[0082] In the above-described technical solution of this application, the handle 2 is equipped with an installation component 22. The installation component 22 engages with the rotating part 113 of the roller brush 1 via a locking pin 221. By changing the position of the locking pin 221, the handle 2 can switch between two states: being restricted from detaching from the mounting base 11 and being detachable from the mounting base 11. This allows the handle 2 to be quickly attached to and detached from the roller brush 1, making operation convenient. In this solution, the structural modifications to the roller brush assembly 100 are minimal, reducing manufacturing costs. The handle 2 of this solution can be used on any roller brush 1 with a mounting hole 111, making it widely applicable.

[0083] In one embodiment, the mounting assembly 22 further includes a locking member 222 and a locking sleeve 223. The circumferential surface of the locking pin 221 is provided with a groove 2211 and an abutment portion 2212. The locking sleeve 223 is sleeved on the locking pin 221 and is provided with a through hole 2231. The locking member 222 is movably inserted into the through hole 2231.

[0084] The locking pin 221 can switch between a first position and a second position. By changing its position, the locking pin 221 adjusts the position of the locking member 222 in the through hole 2231.

[0085] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, when the locking pin 221 is in the first position and the handle 2 is installed in the target installation position, the locking sleeve 223 is inserted into the mounting hole 111, the abutment portion 2212 is opposite to the locking member 222, and the surface of the abutment portion 2212 presses the locking member 222 in the direction toward the outside of the through hole 2231. In this way, the locking member 222 can partially extend to the outside of the through hole 2231 under the abutment of the abutment portion 2212, so that the locking member 222 abuts against the rotating member 113 in the disengagement direction of the handle 2, so as to realize the restrictive cooperation between the locking pin 221 and the rotating member 113. When the locking pin 221 is in the second position (not shown in the figure), the groove 2211 is opposite to the locking member 222. The groove 2211 can at least partially receive the locking member 222 so that the locking member 222 is retracted into the through hole 2231. Thus, the locking member 222 does not protrude outside the through hole 2231, or the locking member 222 protrudes slightly outside the through hole 2231.

[0086] With the handle 2 installed in the target installation position, the locking sleeve 223 is inserted into the mounting hole 111, and the locking pin 221 is switched to the first position so that the locking member 222 extends partially out of the through hole 2231, thereby causing the locking member 222 to abut against the mounting base 11 in the disengagement direction of the handle 2, so as to restrict the locking sleeve 223 from disengaging from the mounting base 11 in the disengagement direction of the handle 2. At this time, the locking member 222 is in the locked position.

[0087] When it is necessary to disassemble or install the handle 2, switch the locking pin 221 to the second position so that the locking element 222 retracts into the through hole 2231, thereby allowing the locking sleeve 223 and the locking element 222 to pass through the mounting hole 111. Specifically, when it is necessary to install the handle 2, switch the locking pin 221 to the second position so that the locking sleeve 223 can be inserted into the mounting hole 111, thereby installing the handle 2. At this time, the locking element 222 is in the unlocked position. When it is necessary to remove the handle 2, switch the locking pin 221 to the second position so that the locking sleeve 223 can be pulled out from the mounting hole 111, thereby removing the handle 2.

[0088] It should be understood that during the loading and unloading of the handle 2, when the locking pin 221 is switched to the second position, if the locking member 222 can also slightly extend outside the through hole 2231, the extended portion of the locking member 222 is insufficient to prevent the locking sleeve 223 from being pulled out of the mounting hole 111. This can be achieved by limiting the size of the extended portion of the locking member 222, allowing it to be smoothly pulled out of the mounting hole 111 along with the locking sleeve 223. Alternatively, the locking member 222 can be configured as a component with a certain elastic deformation capability, so that it undergoes slight deformation due to compression, allowing it to be smoothly pulled out of the mounting hole 111 along with the locking sleeve 223. Preferably, to facilitate quick loading and unloading of the handle 2, when the locking pin 221 is in the second position, the locking member 222 does not extend outside the through hole 2231.

[0089] In the above technical solution, the mounting component 22, through the cooperation of the locking pin 221, the locking member 222, and the locking sleeve 223, allows the handle 2 to be quickly mounted and dismounted from the roller brush 1, making operation convenient. By changing its position, the locking pin 221 can adjust the position of the locking member 222 in the through hole 2231 of the locking sleeve 223, allowing the locking member 222 to switch between the locked and unlocked positions. Furthermore, when the locking member 222 is in the locked position, it abuts against the mounting base 11 along the disengagement direction of the handle 2, thereby preventing the locking sleeve 223 from disengaging from the mounting base 11 along the disengagement direction of the handle 2. This solution requires minimal structural modification to the roller brush 1, reducing manufacturing costs. The handle 2 of this solution can be used on any roller brush 1 with a mounting hole 111, making it widely applicable.

[0090] In one embodiment, when the handle 2 needs to be installed, the locking pin 221 is first switched to the second position so that the locking member 222 is retracted into the through hole 2231. The locking member 222 moves to the unlocked position. Then, the locking sleeve 223 of the mounting assembly 22 is aligned with the mounting hole 111 and inserted. During the process of the locking sleeve 223 passing through the mounting hole 111 along the first direction a, the locking member 222 can pass through the mounting hole 111 along the first direction a, avoiding the locking member 222 from colliding with the mounting base 11 due to excessive extension outside the through hole 2231, thereby preventing the locking sleeve 223 from being unable to be inserted into place.

[0091] like Figure 2 and Figure 5As shown, when the handle 2 reaches the target installation position, the locking pin 221 is switched to the first position, so that the locking member 222 partially extends out of the through hole 2231. The locking member 222 moves to the locked position, so that the part of the locking member 222 extending out of the through hole 2231 can abut against the rotating member 113 along the second direction b, thereby preventing the locking sleeve 223 from disengaging from the roller brush 1 along the second direction b. The first direction a is opposite to the second direction b. The first direction a is the installation direction of the handle 2, and the second direction b is the disengagement direction of the handle 2.

[0092] When it is necessary to remove the handle 2, first switch the locking pin 221 to the second position so that the locking member 222 retracts into the through hole 2231. The locking member 222 moves to the unlock position. Then pull the handle 2, and the locking sleeve 223 is pulled out from the mounting hole 111. The locking member 222 can pass through the mounting hole 111 along the second direction b, so that the locking sleeve 223 can smoothly disengage from the roller brush 1 along the second direction b.

[0093] In one implementation, such as Figure 1 and Figure 9 As shown, one end of the cylinder 12 is connected to the mounting base 11, and the other end is connected to the machine body. Both the first direction a and the second direction b extend along the axial direction of the cylinder 12.

[0094] Furthermore, such as Figure 1 and Figure 2 As shown, in order to improve the appearance of the roller brush 1 and to minimize the axial length of the roller brush 1, the mounting base 11 is at least partially embedded in the port at one end of the cylinder 12.

[0095] In one implementation, such as Figure 2 , Figure 5 and Figure 6 As shown, in order to improve the stability of the locking member 222 abutting against the mounting base 11, the number of locking members 222 is at least two, for example, two, three or even more. The number of through holes 2231 provided in the locking sleeve 223 is the same as the number of locking members 222, and the through holes 2231 and locking members 222 are matched one by one.

[0096] In one implementation, such as Figure 2 and Figure 6As shown, the mounting assembly 22 is also provided with a limiting structure 2232. When the handle 2 is in the target mounting position, the limiting structure 2232 abuts against the mounting base 11 along the mounting direction (first direction a) of the handle 2. At the same time, the locking member 222 abuts against the mounting base 11 along the disengagement direction (second direction b) of the handle 2. The limiting structure 2232 and the locking member 222 clamp the mounting base 11 in opposite directions, thereby restricting the displacement of the handle 2 relative to the roller brush 1 in the first direction a or the second direction b, thereby locking the handle 2 to the roller brush 1.

[0097] Furthermore, such as Figure 2 and Figure 6 As shown, the limiting structure 2232 is disposed on the outer wall of the locking sleeve 223. Specifically, when the handle 2 is installed on the roller brush 1, the locking sleeve 223 is inserted into the mounting hole 111. The gap between the locking sleeve 223 and the mounting base 11 is small. By disposing the limiting structure 2232 on the outer wall of the locking sleeve 223, the purpose of the limiting structure 2232 abutting against the mounting base 11 can be achieved while meeting the requirement of miniaturization design of the limiting structure 2232. Of course, the arrangement of the limiting structure 2232 is not limited to this, and it can also be disposed on other parts of the handle 2.

[0098] Furthermore, such as Figure 2 and Figure 6 As shown, the limiting structure 2232 is a protruding structure, which is simple in structure and easy to process.

[0099] In one implementation, such as Figures 2 to 5 As shown, the rotating component 113 is configured as a bearing, and the mounting base 11 also includes a base 112. The rotating component 113 is mounted on the base 112, and the inner ring of the rotating component 113 forms a mounting hole 111. When the handle 2 is in the target mounting position, the locking sleeve 223 passes through the rotating component 113 so that the roller brush 1 can rotate relative to the handle 2. Furthermore, the locking component 222 abuts against the inner ring of the rotating component 113 along the disengagement direction of the handle 2 (second direction b) to prevent the locking sleeve 223 from disengaging from the roller brush 1. In this solution, the handle 2 is assembled by the rotating component 113, so that the roller brush 1 can rotate independently of the handle 2 during operation, that is, the handle 2 does not rotate with the roller brush 1. It should be explained that when the roller brush assembly 100 is installed on the machine body, the handle 21 is restricted by the machine body. For example, the machine body is provided with a handle storage groove (not shown in the figure), and the handle 21 is housed in the handle storage groove. In this way, when the roller brush 1 rotates, the handle 21 does not rotate.

[0100] In one implementation, such as Figure 2 , Figure 5 and Figure 6As shown, the locking member 222 is spherical, with a simple structure. Furthermore, the spherical surface of the locking member 222 facilitates its smooth insertion into or withdrawal from the groove 2211 of the locking pin 221. Of course, the shape of the locking member 222 is not limited to this; it can also be a cylindrical or elliptical structure, and the end of the locking member 222 facing the locking pin 221 is an arc surface or a hemispherical shape.

[0101] In one implementation, such as Figure 2 and Figure 6 As shown, when the locking pin 221 is in the first position, the groove 2211 extends obliquely toward the locking member 222 in the mounting direction of the handle 2, away from the first groove wall 22111 of the handle 21. In this design, the first groove wall 22111 of the groove 2211 is configured as an inclined surface. During the process of the locking member 222 inserting into or withdrawing from the groove 2211, the locking member 222 slides along the surface of the first groove wall 22111. The first groove wall 22111 guides the movement of the locking member 222, which is conducive to the locking member 222 quickly and smoothly switching between the locked and unlocked positions, and avoids the locking member 222 getting stuck.

[0102] In one implementation, such as Figure 6 As shown, the groove 2211 of the locking pin 221 is annular. This reduces the precision requirements for assembling the locking pin 221 and the locking member 222 during assembly and installation of the component 22, thus reducing the assembly difficulty.

[0103] In one implementation, such as Figure 2 and Figure 6 As shown, the mounting assembly 22 also includes an elastic element 224. One end of the elastic element 224 abuts against the locking sleeve 223 along the mounting direction (first direction a) of the handle 2, and the other end is linked with the locking pin 221. During the movement of the locking pin 221 from the first position to the second position, the locking pin 221 compresses the elastic element 224, and the elastic element 224 stores potential energy due to compression. During the movement of the locking pin 221 from the second position to the first position, the elastic element 224 rebounds, providing power for the reset of the locking pin 221. The locking pin 221 can automatically reset, making operation convenient. Furthermore, the elastic element 224 is a spring, resulting in a simple structure.

[0104] Furthermore, such as Figure 2 and Figure 6As shown, the mounting assembly 22 also includes a button 225, which is movably connected to the handle 21 and fixed to the locking pin 221. The other end of the elastic element 224 abuts against the button 225. When the handle 2 needs to be installed or removed, the user can manually press the button 225, which moves the locking pin 221 from the first position to the second position. When the external force is removed, the elastic element 224 rebounds, causing the button 225 to move the locking pin 221 from the second position to the first position. In this design, the button 225 serves two purposes: firstly, it avoids the locking pin 221 being directly exposed, improving the aesthetics of the handle 2; secondly, by increasing the size of the button 225, the pressable contact area is increased, facilitating operation.

[0105] Furthermore, such as Figure 2 and Figure 6 As shown, the handle 21 has a insertion hole 211, and the button 225 has a pressing cover 2251 and a hollow mounting post 2252. The pressing cover 2251 is movably installed in the insertion hole 211, and the end of the locking pin 221 away from the locking member 222 is inserted into the hollow mounting post 2252. Of course, the assembly method of the button 225 and the locking pin 221 is not limited to this. For example, the button 225 and the locking pin 221 can also be screwed together by thread.

[0106] In one implementation, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the mounting assembly 22 also includes a mounting member 226, which has a mounting channel 2261 and a mounting plate 2262. The handle 21 is mounted on the mounting plate 2262. One end of the locking sleeve 223 is installed in the mounting channel 2261, and the through hole 2231 is located outside the mounting member 226. Thus, when the handle 2 is mounted on the roller brush 1 and the locking pin 221 is in the first position, since the locking sleeve 223 is locked to the mounting base 11, the mounting member 226 and the handle 21 are locked to the mounting base 11, thereby locking the handle 2 to the roller brush 1. In this solution, the handle 21 and the locking sleeve 223 are indirectly connected through the mounting member 226. Compared with the solution of directly connecting the handle 21 and the locking sleeve 223, the structural complexity of the handle 21 can be reduced, and the processing cost of the handle 21 can be reduced.

[0107] Furthermore, such as Figure 2 , Figure 6 and Figure 8As shown, one end of the locking sleeve 223 is provided with a first engaging portion 2233, and the mounting channel 2261 is provided with a second engaging portion 22611. The locking sleeve 223 and the mounting channel 2261 are assembled by engaging the first engaging portion 2233 and the second engaging portion 22611. One of the first engaging portion 2233 and the second engaging portion 22611 has at least a groove, and the other has at least a engaging protrusion. Assembly is achieved through the engagement of the groove and the engaging protrusion. Furthermore, to improve the stability of the engagement between the locking sleeve 223 and the mounting channel 2261, both the first engaging portion 2233 and the second engaging portion 22611 are annular to increase the contact area between them.

[0108] In one implementation, such as Figure 2 and Figure 4 As shown, the mounting base 11 has a recess 1121 on the side facing the handle 21. When the handle 2 is in the target installation position, the mounting component 22 is at least partially embedded in the recess 1121 to avoid the handle 2 protruding too much from the roller brush 1. This helps to reduce the overall size of the roller brush assembly 100 and improve its appearance. In addition, the mounting plate 2262 covers the open end of the recess 1121 to improve the aesthetics of the assembly between the roller brush 1 and the handle 2 and to prevent dust and other dirt from entering the recess 1121 and causing cleaning burden.

Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
