Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning equipment, in particular to a cleaning tool with adjustable width. Background Art

[0002] In daily life, household cleaning tools (such as mops, brooms, etc.) are generally provided with a mop strip or bristles at the bottom of a plate of fixed width for mopping or sweeping. However, due to the complexity of the household cleaning environment, it is necessary not only to clean the open ground and walls, but also to clean the gaps between furniture. At this time, cleaning tools with fixed widths are difficult to meet the needs. If the width of the cleaning tool is too wide, it cannot meet the cleaning needs of the gaps between furniture. If the width is too narrow, the cleaning efficiency of the open ground, walls and other areas is low.

[0003] Therefore, it is necessary to provide a household cleaning tool that can adjust the width according to different cleaning environments. Utility Model Content

[0004] In view of this, the utility model provides a cleaning tool with adjustable width to solve the problem that the width of the existing household cleaning tools cannot be adjusted according to different cleaning environments.

[0005] In the first aspect, the utility model provides a cleaning tool with adjustable width, comprising: a rod body, a cleaning head, the cleaning head is connected to the lower end of the rod body, and comprises a plurality of cleaning modules, each of the cleaning modules comprises two adjacently arranged cleaning blocks and two adjacently arranged mounting seats, a cleaning body is provided at the lower part of the cleaning block, in each of the cleaning modules, any one of the cleaning blocks is movably connected to the lower side of each of the mounting seats, so that the cleaning blocks in the plurality of cleaning modules have a first state of being close to each other and a second state of being far away from each other, when the cleaning block is in the first state, the cleaning head has a first width, and when the cleaning block is in the second state, the cleaning head has a second width, and the first width is smaller than the second width.

[0006] Beneficial effect: Each cleaning module includes two adjacent cleaning blocks and two adjacent mounting seats, and any cleaning block is movably connected to each mounting seat, so that the two cleaning blocks in each cleaning module and the two adjacent mounting seats form a quadrilateral structure, the two cleaning blocks and the two mounting seats are respectively the opposite sides of the quadrilateral structure, the movable connection point is the vertex of the quadrilateral, the quadrilateral structure can be deformed, so that the total extension length of the cleaning bodies on the two cleaning blocks changes, and the total width of the cleaning head can be widened or narrowed.

[0007] In an optional embodiment, several of the cleaning modules include at least a first cleaning module and a second cleaning module, in which one of the cleaning blocks in the first cleaning module is movably connected to one of the mounting seats in the second cleaning module, and one of the mounting seats is movably connected to one of the cleaning blocks in the second cleaning module, so that when the two cleaning blocks in the first cleaning module are switched from the first state to the second state or from the second state to the first state, the two cleaning blocks in the second cleaning module are driven to switch from the first state to the second state or from the second state to the first state.

[0008] Beneficial effect: When the cleaning blocks in the first cleaning module move closer to or farther from each other, the cleaning blocks and the mounting seat drive the cleaning blocks in the second cleaning module to move closer to or farther from each other, thereby changing the overall width of the cleaning head.

[0009] In an optional embodiment, a plurality of the cleaning modules are arranged in sequence along the width direction of the cleaning head, so that the cleaning blocks and the mounting seats in the plurality of cleaning modules are arranged in sequence along the width direction of the cleaning head.

[0010] Beneficial effect: Several cleaning modules are arranged in sequence, which makes it easier to drive different cleaning modules to each other when the width of the cleaning head needs to be changed, and enables the width of different cleaning modules to change along one direction.

[0011] In an optional embodiment, along the width direction of the cleaning head, the mounting seats connected to each cleaning block are arranged adjacent to each other; and the cleaning blocks connected to each mounting seat are arranged adjacent to each other.

[0012] Beneficial effects: Since the two mounting seats and the two cleaning blocks in a single cleaning module are arranged adjacent to each other, and several cleaning modules are arranged in sequence, there will be no staggering between the mounting seats of different cleaning modules, and there will be no staggering between the cleaning blocks of different cleaning modules. When the width of the cleaning head changes, the various components will not conflict with each other, and the cleaning head will have better integrity and appearance. At the same time, the cleaning blocks are arranged in sequence, so that the cleaning bodies at their lower parts can also be arranged in sequence, which is convenient for the continuity of the cleaning bodies.

[0013] In an optional embodiment, the cleaning block includes a first movable connection position movably connected to the mounting seat, and the mounting seat includes a second movable connection position movably connected to the cleaning block. In each cleaning module, the distance between two of the first movable connection positions on any cleaning block is equal to the distance between two adjacent first movable connection positions on another cleaning block, and the distance between two of the second movable connection positions on any mounting seat is equal to the distance between two adjacent second movable connection positions on another mounting seat.

[0014] Beneficial effect: The distance between the two first movable connection positions on any cleaning block is equal to the distance between the two adjacent first movable connection positions on the other cleaning block, so that in each cleaning module, the lengths of the two pairs of sides of the quadrilateral formed by the mounting seat are equal, and the distance between the two second movable connection positions on any mounting seat is equal to the distance between the two adjacent second movable connection positions on the other mounting seat, so that in each cleaning module, the lengths of the two pairs of sides of the quadrilateral formed by the cleaning blocks are equal, and thus the quadrilateral structure composed of the two cleaning blocks and the two adjacently arranged mounting seats in each cleaning module is a parallelogram structure. Obviously, the parallelogram structure has a larger deformation amplitude than the non-equilateral quadrilateral (trapezoid, etc.), which can make the width variation range of the cleaning head larger.

[0015] In an optional embodiment, the cleaning block includes a first movable connection position movably connected to the mounting seat, and the mounting seat includes a second movable connection position movably connected to the cleaning block, and the first movable connection position on any of the cleaning blocks are arranged in sequence in the same straight line, and the second movable connection position on any of the mounting seats are arranged in sequence in the same straight line.

[0016] Beneficial effects: Arranged in a straight line, the overall structure is neater, and the mounting bases and cleaning blocks between adjacent modules are arranged more orderly.

[0017] In an optional embodiment, an arrangement direction of the first movable connection positions on any cleaning block is parallel to an arrangement direction of the first movable connection positions on an adjacent cleaning block.

[0018] Beneficial effect: The arrangement direction of the first movable connection position on any cleaning block is parallel to the arrangement direction of the first movable connection position on the adjacent cleaning block, so that the arrangement directions of the two cleaning blocks in the same cleaning module are parallel, and the arrangement directions of the cleaning blocks between different modules are also parallel, so that multiple continuous parallelogram structures are formed on the cleaning head, the deformation amplitude is larger, and the deformation method is simpler.

[0019] In an optional embodiment, the side surface of any cleaning block close to the adjacent cleaning block is parallel to the arrangement direction of the first movable connection position thereon, and the side surface of any mounting seat close to the adjacent mounting seat is parallel to the arrangement direction of the second movable connection position thereon.

[0020] Beneficial effects: adjacent sides of adjacent cleaning blocks remain parallel, thereby better ensuring that adjacent mounting seats and adjacent cleaning blocks do not conflict when the width of the cleaning head changes, better ensuring smoothness when the width of the cleaning head changes. At the same time, the adjacent sides are parallel to each other, making the overall arrangement more regular and the cleaning head more beautiful.

[0022] Beneficial effects: The first type of cleaning block is located at the edge of the cleaning head, and one side of it is not connected to the mounting seat, so it only needs to be connected to two mounting seats, so only two first movable connection positions are needed; the second type of cleaning block is located in the middle, and it not only needs to be connected to the mounting seat in the cleaning module where it is located, but also needs to be connected to a mounting seat in the adjacent cleaning module, so three first movable connection positions are required; the setting logic of the number of second movable connection positions on the mounting seat is consistent with the setting logic of the number of first movable connection positions on the cleaning block. This setting method is the simplest way that multiple cleaning modules can be continuously movable and deformed.

[0023] In an optional embodiment, a limiting device is provided on the cleaning block. When the cleaning block is in the second state, the limiting device limits the movement of the cleaning block along a first direction, wherein the first direction is perpendicular to the axial direction of the active connection between the cleaning block and the mounting seat, and is perpendicular to the direction in which the cleaning blocks approach each other.

[0024] Beneficial effect: The cleaning block is movably arranged on the lower side of the mounting seat, and a limiting device is provided, so that when the cleaning head is in use, the cleaning block can avoid shaking due to the movable gap with the mounting seat, avoid the noise caused by it, and provide a better user experience.

[0025] In an optional embodiment, when the cleaning blocks in the plurality of cleaning modules are arranged in sequence along the approach direction of the cleaning blocks, the limiting device includes a first limiting rod extending along the approach direction of the cleaning blocks, and part of the cleaning blocks are inserted through the first limiting rod.

[0028] Beneficial effect: One end of the first limiting rod is rotatably connected to a first-type cleaning block, so that the first limiting rod will not separate from the cleaning head, and the direction of the first-type cleaning block can be adjusted accordingly during the movement of the first-type cleaning block; the first limiting rod passes through the second-type cleaning block, so that the first-type cleaning block and the second-type cleaning block are arranged along the extension direction of the first limiting rod, and then the first-type cleaning block and the second-type cleaning block are both limited, thereby avoiding gaps in the cleaning head during use.

[0029] In an optional embodiment, the limiting device also includes a second limiting rod passed through the cleaning block, the second limiting rod passed through the first limiting rod, the first limiting rod and the second limiting rod are respectively rotatably connected to two of the first-type cleaning blocks, and when the cleaning blocks approach or move away from each other, the first limiting rod and the second limiting rod slide relative to each other.

[0030] Beneficial effect: by setting two limit rods that penetrate each other and can slide relative to each other, and the first limit rod and the second limit rod are respectively rotatably connected to the two first-type cleaning blocks, all the first-type cleaning blocks and the second-type cleaning blocks can be connected to the limit device, and all the cleaning blocks are limited by the limit device, so that the entire cleaning head forms a whole in the limiting direction without shaking; and the first limit rod and the second limit rod can slide relative to each other, so that during the width change of the cleaning head, the cleaning block is always penetrated by the limit device, and the structure is simple.

[0031] In an optional embodiment, a first rotating body is provided on the cleaning block, and a second rotating body is provided on the mounting seat. When the first rotating body is a rotating shaft or an axial hole, the second rotating body axial hole or rotating shaft, the rotating shaft is passed through the axial hole so that the first rotating body and the second rotating body form a hinge.

[0032] Beneficial effect: The matching mode of the rotating shaft and the shaft hole is simple, which is convenient for design and processing.

[0033] In an optional embodiment, the rotating shaft includes a plurality of side shafts arranged at intervals, and the side shaft includes a shaft body and a protrusion.

When the rotating shaft is passed through the shaft hole, the shaft body is located in the shaft hole, and the protrusion is clamped on one side of the shaft hole.

[0034] Beneficial effect: The protrusion at one end of the side shaft can form a limit for the cooperation between the rotating shaft and the shaft hole to prevent the rotating shaft from sliding in the shaft hole; by setting a number of spaced side shafts, when the rotating shaft is assembled into the shaft hole, when the protrusion passes through the shaft hole, the several side shafts are close to each other, so that the rotating shaft can be assembled into the shaft hole, the structure is simple, the assembly is convenient, and the positioning method has a good effect.

[0049] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0050] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0054] According to an embodiment of the present utility model, on the one hand, a cleaning tool with adjustable width is provided, such as Figure 1 , Figure 2 As shown, it includes a rod body 1 and a cleaning head 2, wherein the cleaning head 2 is connected to the lower end of the rod body 1, wherein the cleaning head 2 includes a plurality of adjacently arranged cleaning blocks 21 and a plurality of adjacently arranged mounting seats 22, and a cleaning body 211 is provided at the lower part of the cleaning block 21, wherein every two adjacently arranged cleaning blocks 21 and the corresponding adjacently arranged mounting seats 22 can form a cleaning module, and in each cleaning module, any cleaning block 21 is movably connected to the lower side of each mounting seat 22, so that in each cleaning module, two cleaning blocks 21 and two mounting seats 22 can form a quadrilateral structure Since the quadrilateral structure has a certain deformation ability, for example, the shape of a parallelogram can be flexibly changed into a rectangle, the maximum length of the quadrilateral structure can be changed, so the distance between the cleaning blocks 21 can be changed, that is, when the two cleaning blocks 21 are close to each other, the maximum length of the quadrilateral structure becomes smaller, which is the first state. At this time, the entire cleaning head 2 has a first width with a smaller width. When the two cleaning blocks 21 are away from each other, the maximum length of the quadrilateral structure becomes larger, which is the second state. At this time, the entire cleaning head 2 has a second width with a larger width.

[0055] It should be noted that only two cleaning blocks 21 and two mounting seats 22 can be set on the cleaning head 2 to form only one cleaning module, that is, the "several" in this patent should be understood as at least one; in addition, the cleaning blocks 21 and mounting seats 22 included in the two cleaning modules can partially overlap. For example, when the cleaning head 2 includes an odd number of cleaning blocks 21 and a corresponding number of mounting seats 22, taking the odd number as three as an example, three consecutively arranged cleaning blocks 21 and three consecutively arranged mounting seats 22, the cleaning blocks 21 and mounting seats 22 located in the middle position can respectively form a cleaning module with the cleaning blocks 21 and mounting seats 22 on both sides, so the three consecutively arranged cleaning blocks 21 and three consecutively arranged mounting seats 22 can form at least two cleaning modules.

[0056] In this embodiment, between two adjacent cleaning modules, a cleaning block 21 of the first cleaning module is movably connected to a mounting seat 22 of the second cleaning module, and a mounting seat 22 of the first cleaning module is movably connected to a cleaning block 21 of the second cleaning module, so that when the two cleaning blocks 21 of the first cleaning module approach or move away from each other, the two cleaning blocks 21 of the second cleaning module are directly or indirectly driven to approach or move away from each other.

[0057] Specifically, taking four adjacent cleaning blocks 21 and four mounting seats 22 as an example, reference can be made to Figure 2 and Figure 3 , and the cleaning blocks 21 and the mounting seats 22 on the left side of the figure are used as the cleaning module. The cleaning blocks 21 and the mounting seats 22 on the left side constitute the first cleaning module, and the cleaning blocks 21 and the mounting seats 22 on the right side constitute the second cleaning module. When the cleaning blocks 21 of the first cleaning module move away from or closer to each other, the third cleaning block 21 and the third mounting seat 22 from left to right can be driven to move, thereby driving the entire second cleaning module to move, that is, the cleaning blocks in the second cleaning module also move away from or closer to each other.

[0058] In the present embodiment, several cleaning modules are arranged in sequence along the approach direction of the cleaning block 21 (i.e., the width direction of the cleaning head 2). Since in each cleaning module, two cleaning blocks 21 are arranged adjacent to each other, two mounting seats 22 are also arranged adjacent to each other, and the cleaning block 21 is installed on the lower side of the mounting seat 22, when all the cleaning modules are arranged in sequence along the approach direction of the cleaning block 21, all the cleaning blocks 21 will be arranged in sequence along the approach direction of the cleaning block 21, and all the mounting seats 22 will also be arranged in sequence along the approach direction of the cleaning block 21, thereby making the cleaning body 21 connected to the lower part of the cleaning block 21 be arranged in sequence along the approach direction of the cleaning block 21, and since the cleaning body 211 is provided as a whole at the lower part of the cleaning block 21, the cleaning body 211 is always continuous in the approach direction of the cleaning block 21, which can ensure that no cleaning gaps are generated during the cleaning process, thereby avoiding unclean cleaning.

[0059] Specifically, the cleaning body 211 may be a bundle of bristles covering the lower part of the cleaning block 21 , or a mop strip, and the bundle of bristles or the mop strip hangs down from the lower side of the cleaning block 21 .

[0060] In the embodiment of the cleaning tool with adjustable width, the mounting seats 22 connected to each cleaning block 21 are arranged adjacent to each other along the approach direction of the cleaning block 21, and the cleaning blocks 21 connected to each mounting seat 22 are also arranged adjacent to each other. This can avoid the cleaning blocks 21 between different cleaning modules from being staggered, and can also avoid the mounting seats 22 between different cleaning modules from being staggered.

[0061] Specifically, taking four consecutive mounting seats 22 and four consecutive cleaning blocks 21 as an example, they are numbered as the first, second, third, and fourth mounting seats 22 (or cleaning blocks 21) from left to right. When the mounting seats 22 connected to each cleaning block 21 are arranged adjacent to each other along the approach direction of the cleaning block 21, the first, second, and third mounting seats 22 can all be connected to the second cleaning block 21. Similarly, the first, second, and third cleaning blocks 21 can all be connected to the second mounting seat 22.

[0062] In this embodiment, the position on the cleaning block 21 that is movably connected to the mounting seat 22 is the first connection position, and the position on the mounting seat 22 that is movably connected to the cleaning block 21 is the second connection position. In each cleaning module, the distance between two adjacent first movable connection positions on any cleaning block 21 is equal to the distance between two adjacent first movable connection positions on another cleaning block 21. This connection method makes it possible for the two opposite sides of the quadrilateral formed by the cleaning block 21 and the mounting seat 22 in each cleaning module to be equal in length. Similarly, when the distance between two adjacent second movable connection positions on any mounting seat 22 is equal to the distance between two adjacent second movable connection positions on another cleaning block 21, the two opposite sides of the cleaning block 22 are equal in length. Therefore, the quadrilateral in each cleaning module is a parallelogram. Compared with other quadrilaterals such as a trapezoid, the deformation amplitude of the parallelogram can be larger, and it can be continuously located in multiple continuously arranged cleaning modules and deform synchronously at the same time, so that the width variation range of the cleaning head 2 is larger and the composition method is simpler and more beautiful.

[0063] In an optional embodiment, the position on the cleaning block 21 that is movably connected to the mounting seat 22 is the first connection position, and the position on the mounting seat 22 that is movably connected to the cleaning block 21 is the second connection position. The first movable connection positions on any cleaning block 21 are arranged in sequence in the same straight line, and the second movable connection positions on any mounting seat 22 are arranged in sequence in the same straight line, so that the mounting seats 22 on each cleaning block 21 can move synchronously, avoiding mutual influence between the mounting seats 22 on the same cleaning block 21.

[0064] Furthermore, the arrangement direction of the first movable connection positions on any cleaning block 21 is parallel to the arrangement direction of the first movable connection positions on its adjacent cleaning block 21. When the arrangement directions of the first movable connection positions on all the cleaning blocks 21 are parallel, that is, in the same cleaning module, the sides of the quadrilateral where the two cleaning blocks 21 are located are parallel, and similarly, the sides of the quadrilateral where the two mounting seats 22 are located are parallel. Therefore, the quadrilateral in each cleaning module is a parallelogram, and its effect is consistent with the parallelogram effect in the above embodiment, which will not be repeated here.

[0065] In this embodiment, the side of any cleaning block 21 close to the adjacent cleaning block 21 is parallel to the arrangement direction of the first movable connection position thereon, that is, on each cleaning block 21, the side adjacent to another cleaning block 21 is parallel to the side of the parallelogram in which it is located. Therefore, when each cleaning module changes, the two cleaning blocks 21 included therein always maintain a parallel relationship as a whole, adapting to the direction of the connection line of their first connection positions, avoiding conflict due to the non-parallelism of adjacent sides during their deformation.

[0066] Similarly, the side surface of any mounting seat 22 close to the adjacent mounting seat 22 is parallel to the arrangement direction of the second movable connection position thereon, so that when each cleaning module changes, the two mounting seats 22 included therein always maintain a parallel relationship as a whole, and the effect is similar to that of the cleaning block 21 mentioned above.

[0067] Specifically, the projection of the cleaning block 21 along the rod body 1 can be a parallelogram such as a rectangle, and the projection shape of each cleaning block 21 is the same, and the projection of the mounting seat 22 along the rod body 1 is also corresponding, which will not be repeated here.

[0068] Furthermore, if Figure 3 , Figure 4 As shown, along the approach direction of the cleaning block 21, that is, the left-right direction in the figure, the cleaning block 21 includes a first type of cleaning block located at both ends, and a second type of cleaning block arranged between the two first type of cleaning blocks, each of the first type of cleaning blocks is provided with two first movable connection positions, that is, each of the first type of cleaning blocks can only be included in one cleaning module, and each of the second type of cleaning blocks is provided with three first movable connection positions, that is, each of the second type of cleaning blocks is included in two cleaning modules, and each two consecutive first type of movable connection positions on each second type of cleaning block are in two different cleaning modules. Accordingly, the mounting seat 22 includes the first type of cleaning blocks located at both ends. A first type of mounting seat and a second type of mounting seat arranged between two first type mounting seats, and the arrangement method is the same as that of the cleaning block 21. This method can realize that the two mounting seats 22 inside each cleaning module and the two cleaning blocks 21 form a parallelogram structure, and can make a mounting seat 22 and a cleaning block 21 in a cleaning module simultaneously serve as two adjacent sides of the parallelogram structure in another cleaning module, ensuring that multiple continuous cleaning modules can be linked, that is, when in use, only one cleaning module needs to be deformed by external force, and the remaining cleaning modules will also be deformed, so the width of the entire cleaning head 2 will change accordingly,

[0069] In an optional embodiment, the direction perpendicular to the axis of the movable connection between the cleaning block 21 and the mounting seat 22 and the direction perpendicular to the approaching direction of the cleaning block 21 is referred to as the first direction (i.e. Figure 1 A limiting device is provided on the cleaning block 21, and the limiting device can limit the movement of the cleaning block 21 along the first direction. Since the cleaning tool generally includes movement along the first direction when performing cleaning operations, and since the cleaning block 21 is movably arranged on the lower side of the mounting seat 22, the cleaning block 21 is easy to shake or loosen relative to the mounting seat 22 during cleaning operations, and it is also easy to produce noise, which makes the user experience bad. The limiting device limits the movement of the cleaning block 21 in the first direction, which easily solves this problem.

[0070] Furthermore, the limiting device includes a first limiting rod 231, and part of the cleaning blocks 21 are passed through the first limiting rod 231, and the first limiting rod 231 extends along the approach direction of the cleaning blocks 21, so that part of the cleaning blocks 21 passed through the first limiting rod 231 can move away from or approach each other, and can also be limited by the limiting device, that is, the first limiting rod structure 231 also becomes the moving track of these cleaning blocks 21.

[0071] Specifically, when the cleaning block 21 includes a first type of cleaning block and a second type of cleaning block, one end of the first limiting rod 231 is rotatably connected to a first type of cleaning block, and a through hole 213 is provided on the second type of cleaning block for the first limiting rod 231 to pass through, that is, Figure 4 The cleaning block 21 on the right side of the middle part and the first limiting rod 231 are formed in such an implementation mode that the first type of cleaning block and the second type of cleaning block can be connected in series and limited by a limiting device.

[0072] Furthermore, the limiting device also includes a second limiting rod 232, namely Figure 4 The cleaning block 21 on the left side of the middle is composed of the second limiting rod 22, and the first limiting rod 231 and the second limiting rod 232 can slide relative to each other along the direction of the cleaning block 21 approaching or moving away. When the cleaning block 21 is in the second state, at least one of the two side walls of the through hole 213 in the first direction abuts against the first limiting rod 231 or the second limiting rod 232.

[0073] In an optional embodiment, the cleaning block 21 and the mounting base 22 are movably connected in a hinged structure, such as Figure 5 , Figure 6 As shown, a first rotating body 212 is disposed on the upper portion of the cleaning block 21, and a second rotating body 221 is disposed on the mounting seat 22.

[0074] Specifically, the first rotating body 212 and the second rotating body 221 form a rotating shaft and an axial hole, which can not only ensure the movable connection between the cleaning block 21 and the mounting seat 22, but also have a simple and practical design. Obviously, the first rotating body 212 can be a rotating shaft or an axial hole, and correspondingly, the second rotating body 221 can be an axial hole or a rotating shaft.

[0075] Furthermore, if Figure 5As shown, the rotating shaft includes a plurality of side shafts 2121 arranged at intervals, and each side shaft 2121 includes a shaft body 21211 and a protrusion 21212.
