Description

Technical Field

[0001] The present invention relates to the field of cleaning tools, and particularly to a cleaning tool with a quick-release cleaning head. Background Art

[0002] In daily life, cleaning tools are widely used, and a mop is an indispensable cleaning tool. It mainly uses the cotton strips at the lower end of the mop head to wipe the floor and absorb dirt or liquid to achieve the purpose of cleaning the floor.

[0003] For existing rotary mops, in order to facilitate the replacement of the wiping material, the cotton strips are usually fixed on a disc. The mop head is provided with a cavity with an opening at the lower end, and is fixedly connected by a tight fit between the outer circumference of the disc and the inner side wall of the mop head. When disassembling the wiping material, generally, it is necessary to pull hard on the wiping material and the mop to achieve the disassembly of the wiping material. Although consumers have thought of a way to disassemble the wiping material without getting their hands dirty by stepping on the wiping material and pulling up the mop rod, the sewage and stains on the wiping material are still likely to dirty the shoes.

[0004] Existing rotary mops can only be used with specially made cotton strip wiping materials and cannot be adapted to other wiping materials or cleaning heads such as brush heads, and the cleaning function for the floor is relatively single.

[0005] Therefore, there is still much room for improvement in the installation and disassembly structure of the cleaning head of the cleaning tool. Summary of the Invention

[0006] An object of the present invention is to provide a cleaning tool with a quick-release cleaning head to solve the above problems.

[0007] To achieve the above object of the invention, the present invention is realized by the following technical solutions: A cleaning tool with a quick-release cleaning head, comprising a handle and a base. A cleaning head is detachably mounted on the base. The cleaning head includes a mounting plate and a cleaning member. The base is provided with a locking buckle, and the mounting plate is provided with a locking portion for the locking buckle to lock. A positioning mechanism is further provided between the base and the mounting plate. The positioning mechanism includes a first positioning portion and a second positioning portion. The first positioning portion is provided on the mounting plate, and the second positioning portion is provided on the base. When the locking buckle locks the mounting plate, the first positioning portion and the second positioning portion are buckled together to fix the mounting plate on the base. The locking buckle can be moved to detach the mounting plate from the base. The up-and-down limit between the base and the mounting plate is realized through the locking buckle. Even when the outer periphery of the mounting plate and the inner side wall of the base are not tightly fitted or in contact, the fixed connection between the base and the mounting plate can be completed. The mounting plate uses the movement of the locking buckle to limit and fix the installation and release the limit and disassembly between the base and the mounting plate. The cleaning head can be disassembled without contacting it, realizing a non-dirty-hand and more hygienic disassembly of the cleaning head. The setting of the positioning mechanism positions the mounting plate and the base at a height where the locking buckle can cooperate with the mounting plate, preventing the mounting plate from shaking and avoiding misalignment between the locking buckle and the mounting plate and unable to cooperate for limiting. The positioning mechanism can also prevent the cleaning head from rotating relative to the base.

[0008] Preferably, the cleaning member is set as a wiping material or bristles. A mounting plate is arranged on wiping materials in the forms of mops, cotton swabs, cotton threads, etc., and on brush heads or broom heads composed of bristles. By using the detachable connection between the mounting plate and the base, different types of cleaning tools can all adopt the use mode of a detachable cleaning head. At the same time, different types of cleaning heads can also be matched on the base to switch the cleaning tool into different types of mops, or cleaning brushes or brooms. The user can freely replace them according to different needs, thereby expanding the cleaning range and methods of the cleaning tool.

[0009] Preferably, the first positioning portion and / or the second positioning portion is a raised boss. When the locking buckle locks the mounting plate, the mounting plate is supported on the positioning mechanism. When the installation of the mounting plate on the base is completed, the mounting plate is supported by the positioning mechanism to prevent the mounting plate from rotating relative to the base.

[0010] Preferably, a circular or equilateral polygonal mounting groove is provided on the mounting plate, and a first limiting portion is provided at the lower end of the locking buckle. The first limiting portion enters the mounting groove to cooperate with the locking portion to fix the mounting plate. The setting of the circular or equilateral polygonal mounting groove enables the mounting plate to cooperate and fix with the first limiting portion along different directions or different sides, simplifying the alignment during the installation process of the mounting plate.

[0011] Preferably, the first positioning portion is a circle or a plurality of tooth portions arranged equilaterally, and the second positioning portion is provided with a plurality of insertion blocks; or the second positioning portion is a circle or a plurality of tooth portions arranged equilaterally, and the first positioning portion is provided with a plurality of insertion blocks. When the mounting plate is mounted on the base, the insertion blocks can cooperate with any tooth portion for limiting, preventing relative rotation between the mounting plate and the base. The lock can be limited at any angle with the mounting groove or the locking portion. On this basis, the plurality of tooth portions uniformly arranged on the mounting plate enable the lock and the two positioning portions to simultaneously limit the mounting plate in the up-and-down direction and the circumferential direction when the mounting plate cooperates with the mop head at any angle; the cooperation between the tooth portion and the insertion block can, on the basis of circumferentially limiting the mounting plate, also form a support between the top of the mounting plate and the base, so that the first limiting portion is at a relative height where it can extend into the first locking portion, reducing the clearance of the active fit between the first limiting portion and the locking portion. Even when there is zero clearance between the first limiting portion and the locking portion in the up-and-down direction, the support of the tooth portion and the insertion block can still enable the first limiting portion to enter the locking portion to reduce the up-and-down shaking of the mounting plate.

[0012] Preferably, the second positioning portion is elastically and movably connected to the base, enabling the second positioning portion to cooperate with the first positioning portion in a floating manner. When there is a situation where the first limiting portion and the locking portion or the first limiting groove are partially misaligned and cannot enter, the first positioning portion pushes the second positioning portion to float, changing the positions of the mounting plate and the locking portion or the first limiting groove, so that the first limiting portion can be inserted into the locking portion or the first positioning groove, avoiding the situation where the first limiting portion and the locking portion or the first limiting groove are misaligned and cannot cooperate when errors occur during the production and processing process, or when dust, hair and other dirt adhere to the base and the mounting plate during daily use, causing the dimensional changes of the mating positions on the base and the mounting plate.

[0013] Preferably, an elastic body is provided between the second positioning portion and the base. When the lock is disengaged from the locking portion, the elastic force of the elastic body pushes the mounting plate to separate from the base. To enable the disassembly of the cleaning head when the cleaning head and the mounting plate cannot be separated from the base due to gravity, the elastic force of the thin sheet and the elastic body can still achieve the disassembly of the cleaning head.

[0014] Preferably, the side surfaces of any of the tooth parts and any of the insertion blocks are provided as inclined surfaces. When the mounting plate is installed, the tooth part and the insertion block are automatically adjusted to the meshing position through the cooperation of the inclined surfaces, and the positioning mechanism and the first limiting part jointly act to clamp the mounting plate up and down. When the cleaning head is installed, if the mounting plate and the base are not aligned at the position and angle where the tooth part and the insertion block are completely misaligned and meshed, press the base or the mounting plate up and down, and the base or the mounting plate can automatically rotate along the inclined surface to the position and angle where the tooth part and the insertion block are completely misaligned and meshed, without the need to horizontally rotate the base or the mounting plate to adjust the limiting angle, making the installation of the cleaning head more convenient; at the same time, the inclined surfaces of the tooth part and the insertion block can cooperate with the lock and the locking part to jointly adjust the clearance and clamping force between the lock and the upper stop block.

[0015] Preferably, an upper stop block is provided above the locking part, and the first limiting part can be inserted into any position of the locking part and form a support for the upper stop block above. With the setting of the locking part and the upper stop block, the lock can cooperate and be positioned with the locking part at any angle and position. During the installation of the cleaning head, the mounting plate does not need to be deliberately adjusted to a preset angle that can limit the lock, making the installation of the cleaning head more convenient without the need for alignment. The setting of the locking part avoids the locking part located below the mounting plate from contacting the ground and wearing the ground.

[0016] Preferably, a lower stop block is provided below the locking part. A plurality of hair planting holes are provided in the circumferential direction of the mounting plate, and cleaning parts are fixed in the hair planting holes. The cleaning parts are provided as wiping objects, and the wiping objects include a wiping section and a hair planting section. The wiping section extends radially outward along the mounting plate, and the hair planting section extends towards the center of the mounting plate, and the length of the wiping section is greater than the length of the hair planting section. The lower stop block prevents the hair planting section from entering the mounting groove or the locking part. If the hair planting section enters the mounting groove or the locking part, the lock is likely to clamp the hair planting section in the locking part, and even under the influence of the hair planting section, the lock cannot be inserted into the locking part to cooperate and be positioned with the upper stop block, resulting in the wiping object being unable to be installed.

[0017] Preferably, the width of the lower stop block is not less than the length of the hair planting section, or an embedding groove is provided between the hair planting hole and the lower stop block, and at least part of the hair planting section enters the embedding groove to shorten the overlapping length between the hair planting section and the lower stop block. Since it is difficult to shorten the length of the hair planting section with the existing hair planting process, it is necessary to adjust the width and shape of the lower stop block to prevent the hair planting section from entering the mounting groove and the locking part.

[0018] Preferably, a guiding surface is provided on the latch and / or the upper stopper. Align the base with the mounting plate. The first limiting portion and the upper stopper overlap vertically. Press down the handle. The guiding surface guides the latch to move towards the central position of the base until the first limiting portion and the upper stopper are misaligned. The elastic force of the first elastic member causes the first limiting portion to insert into the locking portion. The setting of the guiding surface allows the cleaning head to be placed flat on the ground. Hold the handle and press down. Subject to the vertical abutting force of the mounting plate, the latch can automatically move horizontally, thereby realizing the installation of the cleaning head. During the installation process, there is no need to manually control the movement of the latch, making it more convenient to use.

[0019] The advantages of the present invention are as follows: In the prior art, the inner side walls of the existing mounting plate and the base are fixed by means of tight fitting or clamping. The setting of the latch and the positioning mechanism enables the base and the mounting plate to be limited and fixed for installation and the limit to be released for disassembly even when the inner side walls of the mounting plate and the base are only in contact or not in contact. The cleaning head can be disassembled without touching the base, realizing a cleaner and more hygienic disassembly of the cleaning head without getting hands dirty; The detachable connection between the mounting plate and the base is provided on different types of cleaning heads, enabling different types of cleaning tools to all adopt the usage mode of detachable cleaning heads. At the same time, different types of cleaning heads can also be paired with the base, enabling the cleaning tool to be switched into different types, thereby expanding the cleaning range and methods of the cleaning tool; The cooperation between the first positioning portion and the second positioning portion can prevent the mounting plate from rotating relative to the base. When the base and the mounting plate are set to be circular, the latch can cooperate and position with the mounting plate at any angle and position. The first positioning portion and the second positioning portion can also cooperate at any angle and position. During the installation process of the cleaning head, there is no need to deliberately adjust the mounting plate to a preset limiting angle, making the installation of the cleaning head without the need for alignment and more convenient; The cooperation between the first positioning portion and the second positioning portion can, on the basis of circumferentially limiting the mounting plate, also form a support between the top of the mounting plate and the base, enabling the first limiting portion to be at a relative height where it can extend into the first locking portion, reducing the clearance of the movable fit between the first limiting portion and the locking portion. Even when there is zero clearance in the vertical direction between the first limiting portion and the locking portion, the support between the second positioning portion and the second positioning portion can still enable the first limiting portion to enter the locking portion to reduce the vertical shaking of the mounting plate.

DETAILED DESCRIPTION

[0039] The following describes the embodiments of the present invention in detail in conjunction with the accompanying drawings, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Certain words are used in the present invention to refer to specific components. Those skilled in the art should understand that this specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as the criterion for distinction. It should be noted that, unless otherwise specified, when a component is described as "provided with" or "provided on" or "provided on" another component, it can mean that it is directly provided with or directly provided on another component or there can also be a central component, and it can be an integral structure or a split structure. When a component is described as "connected to" another component, it can be directly connected or connected through a central component, and it can be an integral connection or a split connection or there can be a contact and matching relationship. When a component is described as "provided on another component", it does not mean that the component must be located above or on the upper part of another component, but can also be located in other positions. The terms "upper", "lower", "left", "right", "high", "low" and similar expressions used herein are based on the normal placement state of the product, and are only for the purpose of convenience of explanation. The term "multiple" used herein refers to two or more numbers. The terms "vertical", "horizontal" and the like as used herein refer to a substantially vertical or substantially horizontal state within a reasonable error range and do not necessarily have to be very precise.

[0041] As Figure 1-18 , a cleaning tool with a quick-release cleaning head includes a handle 1 and a base 2. A cleaning head is detachably mounted on the base 2. The cleaning head includes a mounting plate 5 and a cleaning member. The base 2 is provided with a locking buckle 4, and the mounting plate 5 is provided with a locking portion 13 for the locking buckle 4 to insert. A positioning mechanism is further provided between the base 2 and the mounting plate 5. The positioning mechanism includes a first positioning portion 7 and a second positioning portion 8. The first positioning portion 7 is arranged on the mounting plate 5, and the second positioning portion 8 is arranged on the base 2. When the locking buckle 4 locks the mounting plate 5, the first positioning portion 7 and the second positioning portion 8 are buckled to fix the mounting plate 5 on the base 2. The locking buckle 4 can be moved to detach the mounting plate 5 from the base 2. Embodiment 1

[0042] In this embodiment, the cleaning tool is set as a mop, and the cleaning member is set as a wiping object 3 in the form of a mop cloth 9, a rubber cotton, a cotton thread, etc. Since the wiping objects 3 of different materials have different material characteristics, they have their own advantages and disadvantages in terms of water absorption, cleaning power, weight, cost, etc. With the setting of the locking buckle 4, the user can freely select wiping objects 3 of different materials according to different usage scenarios.

[0043] In the prior art, the installation and disassembly methods of wiping objects 3 of different materials are all different. For example Figure 9 , the mop cloth 9 is generally detachably connected to the plush surface on the back of the mop cloth 9 through a magic tape on the base 2, and there is no need to set a mounting plate 5 on the mop cloth 9; for another example, a rubber cotton wiping object is generally detachably connected by inserting or clamping the mounting plate with the base; for another example, a cotton thread wiping object generally fixes the cotton thread on the mounting plate to form a whole, and then is detachably connected to the base through the mounting plate. Moreover, the usage shapes of wiping objects 3 of different materials are also different. For example, the mop cloth 9 and the rubber cotton wiping object are generally strip-shaped or sheet-shaped, and the top of the wiping object needs to be supported by the base 2 or the mounting plate 5 to be used for cleaning the ground; while the cotton thread wiping object is generally disc-shaped, the middle position is supported by the base 2 or the mounting plate 5, and the outer edge position is generally not supported by the base 2 or the mounting plate 5.

[0044] In order to adapt to wiping objects 3 of different materials, for example Figure 9-10 , in this embodiment, wiping objects 3 of different materials are respectively matched with different mounting plates 5, and each mounting plate 5 is then detachably mounted on the base 2 through the same structure.

[0045] On the basis of the above structure, the cleaning member can also be replaced with bristles to form a brush head or a broom head 10. For example Figure 11 , only by fixing the bristles on the mounting plate 5 adopting the above installation and disassembly structure, the cleaning tool can be replaced from a mop to a cleaning brush or a broom, further broadening the cleaning types of the cleaning tool. Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 lies in that: this embodiment takes a mop with a cotton thread wiper 3 installed as an example to illustrate the specific structure.

[0047] The cleaning tool in this embodiment is set as a rotating mop with a cotton thread wiper 3 installed. The mop rod 1' and the mop head 2' on the rotating mop respectively form the handle 1 and the base 2 of the above-mentioned cleaning tool. The rotating mop in this embodiment is the same as that in the prior art, and both are supported in a mop bucket 36 to rotate for cleaning and dewatering. How to drive the mop head 2' to rotate and the structure of how the mop head 2' is cleaned and dewatered are not the inventive points of this embodiment, and will not be elaborated in this embodiment.

[0048] As Figure 4-6 , in this embodiment, the overall shape of the base 2 or the shape of the internal cavity is set as a circle, and the overall shape of the mounting plate 5 is also set as a circle. On the basis of the circular structure, the mounting plate 5 is limited in the up and down directions by a buckle 4, so that the wiper 3 can be disassembled without contacting the wiper 3. The positioning mechanism is used to support the mop head 2' and the mounting plate 5 in the up and down directions and prevent relative rotation between the mop head 2' and the mounting plate 5, which is suitable for driving the wiper 3 to rotate synchronously for cleaning and dewatering during the rotation of the mop head 2'. During the installation and disassembly of the wiper 3, when the buckle 4 is movably limited or the limit is released, the positioning mechanism is automatically limited and the limit is released, and there is no need to separately control the cooperation state of the two limit structures. Of course, the buckle 4 and the positioning mechanism can be set as the same mechanism or different mechanisms. When the buckle 4 and the positioning mechanism are set as the same mechanism, the buckle 4 has the functions of up and down limiting and supporting and positioning, that is, the positioning mechanism in this way is the buckle 4.

[0049] There is also a way in which the existing mop head 2' and the mounting plate 5 are both set as circles, such as Figure 7 , the existing mop head 2' and the mounting plate 5 are fixedly installed by a tight fit method, and the up and down and circumferential limits are realized by the way of pressing between the mop head 2' and the mounting plate 5. When disassembling the wiper 3, it is necessary to pull the wiper 3 and the mop head 2', so that the two are forced to be separated. The hands or feet need to contact the wiper 3, and the operation process is not very hygienic; while in the structure controlled by a switch such as a bolt for installation, although the wiper 3 can be disassembled without getting hands dirty, the mop head 2' and the mounting plate 5 need to be adjusted to a preset angle and position before the switch can be connected to the hole or slot on the mounting plate 5, and precise alignment is required when installing the mop head 2'.

[0050] Based on the existing structure, the buckle 4 adopted in this embodiment can cooperate with the mounting plate 5 at any angle to limit the up and down positions. In addition to supporting and positioning the mop head 2' and the mounting plate 5, the positioning mechanism can also limit the circumferential position of the mop head 2' and the mounting plate 5 at any angle. When installing the wiping object 3, it can be installed without precise alignment, and when disassembling the wiping object 3, only the buckle 4 needs to be manipulated, without touching the wiping object 3. It should be noted that in this embodiment, the up and down directions, the horizontal direction or the transverse direction are referenced with the mop rod 1' and the mop head 2' being perpendicular, and the mop head 2' being horizontally placed on the ground. As Figure 2-3 shown, the up and down direction is the extending direction of the mop rod 1', and the horizontal direction or the transverse direction is the plane direction where the mop head 2' is located. The angle between the mop head 2' and the mounting plate 5 in this embodiment refers to any angle of rotation of the mop head 2' and the mounting plate 5 on the plane where the mop head 2' and the mounting plate 5 are in a parallel position. No matter the mounting plate 5 rotates to any angle on this plane, the buckle 4 can cooperate with the mounting plate 5 rotated to any angle to limit the up and down positions, thereby reducing the installation alignment steps between the buckle 4 and the mounting plate 5.

[0051] To simplify the structures of the mop head 2' and the mounting plate 5, the mounting plate 5 is set as an annular shape in this embodiment. The central cavity of the mounting plate 5 forms an installation groove 6. The buckle 4 can move radially along the mop head 2'. A first elastic member 11 is provided on the buckle 4. The elastic force of the first elastic member 11 makes the buckle 4 keep a tendency to move towards the outer periphery of the mop head 2'. The first limiting portion 12 on the buckle 4 can support under the mounting plate 5. When disassembling the wiping object 3, the buckle 4 moves towards the center of the mop head 2', and the mounting plate 5 separates from the support of the first limiting portion 12 and moves downward to separate from the mop head 2'. Using the central cavity of the mounting plate 5 for the buckle 4 to move and be limited can reduce the thickness of the mop head 2' and the mounting plate 5.

[0052] Preferably, the central cavity of the mounting plate 5 is set as a circular hole, and the first limiting portion 12 at the lower end of the buckle 4 is set as a hook or a pin. The first limiting portion 12 passes through the central cavity downward and is formed under the mounting plate 5. In this structure, the circular hole forms the installation groove 6, and the first limiting portion 12 passes through the installation groove 6 and cooperates with any edge position of the bottom surface of the mounting plate 5 for limiting. The cooperation position of the mounting plate 5 forms a locking portion 13.

[0053] Furthermore, a groove communicating with the circular hole can also be provided on the inner side of the mounting plate 5. The first limiting portion 12 is inserted into the installation groove 6 and cooperates with the groove on the mounting plate 5 for limiting, as Figure 2 shown. This groove can be a sunken surface on the bottom surface of the mounting plate 5, as Figure 3, or it can be a groove extending transversely along the edge of the circular hole. Specifically, a locking portion 13 is provided inside the mounting plate 5. The locking portion 13 communicates with the central cavity of the mounting plate 5 to jointly form a mounting groove 6. It can be understood that the locking portion 13 is a part of the mounting groove 6. An upper stop block 14 is provided above the locking portion 13. The first limiting portion 12 can be inserted into any position of the locking portion 13 and form a support for the upper stop block 14 above. With the settings of the locking portion 13 and the upper stop block 14, the first limiting portion 12 can cooperate with the locking portion 13 at any angle and position for positioning. During the installation process of the wiping object 3, the mounting plate 5 does not need to be deliberately adjusted to a preset angle that can limit the first limiting portion 12, so that the installation of the wiping object 3 does not require alignment, which is more convenient. The setting of the locking portion 13 avoids the ground contact between the limit switch located below the mounting plate 5 and the ground, causing ground wear.

[0054] Preferably, the mounting groove 6 can also be set as an equilateral polygon, and the locking portion 13 is provided on any side of the polygon. The first limiting portion 12 can cooperate with the locking portion 13 on any side for positioning.

[0055] In the wiping object 3 of this embodiment, by providing a plurality of circumferentially arranged hair planting holes 15 on the mounting plate 5, soft and water-absorbing wiping object units such as cloth strips and cotton threads are fixed in each hair planting hole 15. The inner end of the wiping object 3 in the length direction is fixed in the hair planting hole 15 and extends out of the hair planting hole 15 to form a hair planting section 16. The part of the wiping object 3 located outside the hair planting hole 15 can be straightened and opened radially outward along the mounting plate 5 when the mop head 2' rotates, and extends out from the outer periphery of the mop head 2' to expand the mopping area, thereby forming a wiping section 17 for cleaning the ground. When the rotating mop is in a static and suspended position as a whole, the outer part of the wiping section 17 naturally hangs down under the action of gravity below the mop head 2', reducing the area of the horizontal cross-section to enter the mop bucket 36 for cleaning and dehydration.

[0056] Preferably, the length of the wiping section 17 is greater than the length of the hair planting section 16.

[0057] Preferably, a sawtooth-shaped protrusion 18 is provided at the edge of the hair planting hole 15. The protrusion 18 can be inserted into the wiping object 3 to prevent the wiping object 3 from detaching from the hair planting hole 15.

[0058] Since it is difficult to remove the hair planting section 16 by the existing cotton thread fixing process, in order to prevent the hair planting section 16 from entering the mounting groove 6 and hindering the connection between the lock catch 4 and the mounting plate 5, in this embodiment, a lower stop block 19 is provided below the locking portion 13. The lower stop block 19 extends downward or towards the central area of the mounting plate 5, and uses the lower stop block 19 to block the hair planting section 16 from entering the mounting groove 6.

[0059] The lower stop block 19 can block the hair implanting section 16 in the following two ways. First, the width of the lower stop block 19 is not less than the length of the hair implanting section 16. The width of the lower stop block 19 is the distance that the lower stop block 19 extends towards the center of the mounting plate 5. By widening the lower stop block 19, the movement of the locking buckle 4 is prevented from being obstructed by the end of the hair implanting section 16. Second, a groove 20 is provided between the hair implanting hole 15 and the lower stop block 19. After the hair implanting section 16 is pressed, its end inserts into the groove 20, or a part of the hair implanting section 16 is pressed into the groove 20 to shorten the overlapping length between the end of the hair implanting section 16 and the lower stop block 19. The structure of the groove 20 can be that the outer edge of the lower stop block 19 extends downward to form a step, creating a height difference with the hair implanting hole 15, and the space formed by this height difference is the groove 20. The structure of the groove 20 can also be that on the basis of the step formed on the lower stop block 19, the hole wall of the hair implanting hole 15 extends downward to form a frustum, and the recessed space formed between the frustum and the step forms the groove 20. By combining the frustum and the groove 20, the length that the hair implanting section 16 needs to pass through to enter the installation groove 6 is extended, thereby preventing the hair implanting hole 15 from obstructing the locking buckle 4. Of course, in the above two ways, the method of extending the width of the lower stop block 19 and setting the groove 20 can also be used simultaneously to further prevent the end of the hair implanting section 16 from obstructing the locking buckle 4.

[0060] In this embodiment, the width of the lower stop block 19 is greater than the width of the upper stop block 14.

[0061] Such as Figure 5-6,8, specifically introduce the structure of the positioning mechanism. In this embodiment, the positioning mechanism includes a first positioning portion 7 and a second positioning portion 8, the first positioning portion 7 and / or the second positioning portion 8 is a raised boss, the lock 4 locks the mounting plate 5, and supports the mounting plate 5 on the positioning mechanism, the first positioning portion 7 is configured as a plurality of teeth 21 arranged in a circular shape, and the second positioning portion 8 is configured as a plurality of plug blocks 23, and the teeth 21 cooperate with the plug blocks 23 for positioning. Specifically, the first positioning part 7 is set as a face gear 7' on the top surface of the mounting plate 5, and the face gear 7' is provided with a plurality of teeth 21 arranged in a circular ring, and a slot 22 is formed between any two adjacent teeth 21, and the second positioning part 8 is set as a plurality of plug blocks 23 adapted to the slot 22. When the mounting plate 5 and the mop head 2' are installed in an aligned position, the plug blocks 23 are inserted into the slot 22, or the teeth 21 and the plug blocks 23 are staggered and meshed, and the mounting plate 5 is supported and positioned in the upper and lower directions respectively by the cooperation of the plug blocks 23 and the slot 22 and the first limiting part 12. At the same time, the teeth 21 extends upward, and the plug blocks 23 extend downward. The engagement of the teeth 21 and the plug blocks 23 or the plugging of the plug blocks 23 and the slot 22 prevents the mounting plate 5 from rotating relative to the mop head 2' after installation. Therefore, the mounting plate 5 is limited in the upper and lower directions and the circumferential direction on the mop head 2', so that the wiping material 3 can be synchronously rotated with the mop head 2' for washing and dehydration. In other embodiments, the first positioning portion 7 may be configured as a plurality of insert blocks 23, and the second positioning portion 8 may be configured as a plurality of teeth 21 arranged in a circular pattern. When the mounting plate 5 and the mop head 2' are in the mounting position, the insert blocks 23 may engage with any teeth 21 or may be inserted into the slots 22 between any two teeth 21, thereby preventing the mounting plate 5 from rotating relative to the mop head 2'.

[0062] Preferably, the face gear 7' is arranged at the edge of the upper stopper 14, between the mounting groove 6 and the hair implanting hole 15, the locking portion 13 is located below the face gear 7', the locking portion 13 and the center of the face gear 7' are on the same straight line, no partition is arranged in the locking portion 13, and the circumferential direction is positioned by the face gear 7' and the plug block 23. When the wiping material 3 is installed, the mop head 2' and the mounting plate 5 are aligned in the upper and lower positions, one of the mounting plate 5 and the mop head 2' is stationary, and the other is rotated to any angle along the plane where it is located, so that the first limit portion 12 can still cooperate with the locking portion 13, and the plug block 23 can still mesh with the tooth portion 21 of the corresponding angle and position. Of course, the angle at which the plug block 23 and the face gear 7' can cooperate is related to the number of tooth portions 21. The more the number of tooth portions 21, the more angles the plug block 23 can cooperate.

[0063] In this embodiment, there are two latches 4, and the two latches 4 are arranged mirror-symmetrically along the mop rod 1'. The wiping object 3 is disassembled by pressing the two latches 4 simultaneously. The insertion block 23 is arranged in the annular area between the two latches 4. The number of the insertion blocks 23 can be one or can form multiple segments of racks. The insertion block 23 and the latch 4 are arranged in a staggered manner, and can support the upper part of the mounting plate 5 before and after the installation of the mounting plate 5. Even if there is a preset installation gap between the mounting plate 5, the mop head 2', and the latch 4, the support of the insertion block 23 and the face gear 7' can reduce the shaking of the mounting plate 5.

[0064] Preferably, the sides of any tooth part 21 and any insertion block 23 are both arranged as inclined surfaces. During the installation process of the wiping object 3, when the tooth part 21 and the insertion block 23 are not at exactly the fully meshed angle, by applying force in the up and down directions, the tooth part 21 and the insertion block 23 can adjust the angle and position along the inclined surfaces to make the two enter the fully meshed state. In order to avoid the state where the tooth part 21 and the insertion block 23 are exactly at the end abutting and cannot be meshed, the ends of the tooth part 21 and the insertion block 23 can be set as tips or arc segments, so as to expand the angle range for the tooth part 21 and the insertion block 23 to automatically adjust the meshing state, without the need for visual alignment and manual adjustment of the positions of the mop head 2' and the mounting plate 5, and the installation process of the wiping object 3 is more convenient.

[0065] Preferably, the latch 4 is provided with a second limiting part 24 above the first limiting part 12. A groove for inserting the upper stop block 14 is formed between the first limiting part 12 and the second limiting part 24. And when the tooth part 21 and the insertion block 23 are in the meshed state, the bottom surface of the second limiting part 24 is in contact with the top surface of the upper stop block 14, so that smooth movable cooperation can be achieved even when there is a zero installation gap between the first limiting part 12 and the locking part 13. In this embodiment, the inclined surface slopes of the tooth part 21 and the insertion block 23 are the same. Even when there is a zero installation gap between the first limiting part 12 and the locking part 13, or when the first limiting part 12, the mounting plate 5, the tooth part 21, or the insertion block 23 is worn due to use, the position can still be adjusted by the inclined surface cooperation of the tooth part 21 and the insertion block 23 so that the first limiting part 12 can still enter the locking part 13 for positioning.

[0066] In addition to the method of installing the wiper 3 by first pressing the lock 4 to misalign the first limiting portion 12 and the upper stop 14 and then inserting the first limiting portion 12 into the locking portion 13, it can also be installed by applying a downward force to the mop head 2' or the mop rod 1' without pressing the lock 4, pushing the lock 4 to automatically move to a position misaligned with the upper stop 14 and enter the locking portion 13. Specifically, a guiding surface 25 is provided at the lower end of the first limiting portion 12. When the mounting plate 5 is placed at the preset position of the mop head 2', the guiding surface 25 contacts the upper stop 14. When a downward force is applied to the mop head 2', the lock 4 abuts against the upper stop 14 at the position of the guiding surface 25. Under the action of the guiding surface 25, the upper stop 14 pushes the lock 4 to move until it moves to a position where the inner sides of the first limiting portion 12 and the upper stop 14 just fit or separate. Under the action of the first elastic member 11, the first limiting portion 12 is inserted into the locking portion 13 for positioning. Of course, in order to make the movement of the lock 4 smoother, a guiding surface 25 can also be provided at the top edge position of the upper stop 14. Preferably, the guiding surfaces 25 on the first limiting portion 12 and the upper stop 14 are both inclined surfaces.

[0067] Preferably, inner retaining walls 26 and outer retaining walls 27 are respectively provided on the inner and outer sides of the face gear 7'. The inner retaining walls 26 and the outer retaining walls 27 block the horizontal movement of the insertion block 23. The heights of the inner retaining walls 26 and the outer retaining walls 27 are both higher than the height of the tooth portion 21, preventing the tip position of the tooth portion 21 from being knocked and damaged, which affects the installation and disassembly of the mounting plate 5.

[0068] In this embodiment, the lock 4 is horizontally movably installed on the mop head 2'. Specifically, the mop head 2' is provided with a switch groove 28 penetrating up and down. The lock 4 includes an upper cover 29 and a lower cover 30. The upper cover 29 and the lower cover 30 are respectively located on the upper and lower sides of the switch groove 28. The upper cover 29 and the lower cover 30 pass through the switch groove 28 and are fixedly connected into a whole. By pushing the upper cover 29 along the outer surface of the mop head 2', the lock 4 as a whole slides horizontally along the switch groove 28. In order to limit the sliding direction of the lock 4, guiding strips 31 extending into the switch groove 28 are provided on both sides of the switch groove 28. A guiding groove 32 is provided on the lock 4. When the lock 4 is installed, the guiding strips 31 are inserted into the guiding groove 32. The cooperation of the guiding strips 31 and the guiding groove 32 simultaneously has the functions of upper and lower limiting and moving guiding and limiting. The sliding direction limit of the lock 4 can also be set such that the dimensions of the upper cover 29 at the upper end portion of the switch groove 28 and the lower cover 30 at the lower end portion of the switch groove 28 are both larger than the dimension of the switch groove 28. After the upper cover 29 and the lower cover 30 are installed into a whole, the connection portion of the upper cover 29 and the lower cover 30 clamps the edge of the switch groove 28 to achieve the upper and lower limiting and moving guiding and limiting of the lock 4.

[0069] In this embodiment, as Figure 3, the outer side surface of the mounting plate 5 and the inner side surface of the mop head 2' are only fitted in a contacting or mating manner, facilitating the separation of the mounting plate 5 from the mop head 2' under gravity after the lock 4 moves into contact and is limited. In other embodiments, the mounting plate 5 can also be fixed to the bottom surface of the mop head 2', and the outer side surface of the mounting plate 5 no longer contacts the inner side surface of the mop head 2'. Since the limitation of the mop head 2' and the mounting plate 5 in the vertical and horizontal directions is achieved through the cooperation of the first limiting portion 12 and the locking portion 13, and the first positioning portion 7 and the second positioning portion 8, even without the enclosure of the inner side surface of the mop head 2', the mounting plate 5 will not rotate or shake. And without the obstruction of the inner side surface of the mop head 2', the mop head 2' can be used with mounting plates 5 of different shapes and sizes, thereby converting the rotary mop into a flat mop with a mop cloth 9 or a cotton swab wiping material, a brush or a broom with bristles. Embodiment 3

[0070] The difference between this embodiment and the above embodiments is that the base 2 and the mounting plate 5 are set as equilateral polygons.

[0071] Preferably, the shape of the base 2 is set as a regular polygon such as an equilateral triangle, a square, a regular hexagon, etc. When any equilateral polygon is adopted, the lock 4 can cooperate with any side of the polygon for positioning, so as to simplify the alignment in the installation process of the mounting plate 5. The shape of the mounting plate 5 is adapted to the shape of the base 2. The outer edge of the base 2 is provided with a side enclosure extending downward. The side enclosure and the top surface of the base 2 jointly enclose an installation cavity. The mounting plate 5 enters the installation cavity upward. Blocked and surrounded by the side enclosure, the mounting plate 5 cannot rotate relative to the base 2.

[0072] As Figure 9-11 , taking the equilateral triangle as an example, the base 2 and the mounting plate 5 of this embodiment are described. Specifically, the base 2 and the mounting plate 5 are set as equilateral triangles with adapted shapes. The outer side surface of the mounting plate 5 can be fitted with the side enclosure of the base 2 to prevent the mounting plate 5 from rotating relative to the base 2. A triangular installation groove 6 is also provided at the center of the mounting plate 5. The base 2 is provided with a lock 4 at a position corresponding to the installation groove 6. One side of the mounting plate 5 is provided with a first limiting groove 33 communicating with the installation groove 6. The first limiting portion 12 on the lock 4 is inserted into the first limiting groove 33 to limit the mounting plate 5 vertically. The structures of the lock 4, the upper stop block 14 and the lower stop block 19 on both sides of the upper and lower sides of the first limiting groove 33 are the same as those in Embodiment 2, and will not be elaborated in this embodiment.

[0073] Preferably, the first limiting groove 33 is provided on each side of the installation groove 6 at the center of the mounting plate 5, and after rotating the mounting plate 5, the first limiting portion 12 can be connected to the first limiting grooves 33 on different sides.

[0074] In the above embodiments, regardless of the shape of the equilateral polygon of the base 2 and the mounting plate 5, the shape of the central mounting groove 6 can be set to a circle in addition to the equilateral polygon of the corresponding shape, and a plurality of first limiting grooves 33 or locking portions 13 are provided on the side of the circular mounting groove 6.

[0075] Preferably, a first positioning portion 7 is provided on the top surface of the mounting plate 5, and a second positioning portion 8 is provided on the base 2 at a position other than the latch 4. The first positioning portion 7 is provided with a plurality of tooth portions 21, and the second positioning portion 8 is also provided with a plurality of insertion blocks 23. When the mounting plate 5 is connected to the base 2, the tooth portions 21 and the insertion blocks 23 are meshed in a staggered manner to form a support above the mounting plate 5. Under the support cooperation of the tooth portions 21 and the insertion blocks 23, the first limiting portion 12 and the first limiting groove 33 are at the same height, and the first limiting portion 12 can smoothly enter the first limiting groove 33. The shapes of the tooth portions 21 and the insertion blocks 23 are the same as those in Embodiment 2, and will not be described in detail in this embodiment. When there is zero installation clearance between the first limiting portion 12 and the first limiting groove 33 or the first limiting portion 12, the mounting plate 5, the tooth portions 21 or the insertion blocks 23 are worn due to use, the position can still be adjusted by the inclined surface cooperation of the tooth portions 21 and the insertion blocks 23 so that the first limiting portion 12 can still enter the first limiting groove 33 for positioning. And when the mounting plate 5 is not in contact with the side wall, the meshing of the tooth portions 21 and the insertion blocks 23 can prevent the mounting plate 5 from rotating relative to the base 2. Embodiment 4

[0076] The difference between Embodiment 4 and Embodiments 2 and 3 lies in: the structure of the second positioning portion 8.

[0077] In Embodiments 2 and 3, the first positioning portion 7 is integrally formed with the mounting plate 5, and the second positioning portion 8 is integrally formed with the base 2 and is rigidly connected to the base 2. In this embodiment, the second positioning portion 8 is elastically and movably connected to the base 2.

[0078] Specifically, the elastically movable connection structure can adopt the following two methods. The first one: as Figure 12 , the second positioning portion 8 is integrally formed with the base 2, and a thin sheet 34 is also integrally formed between the second positioning portion 8 and the base 2. The thin sheet 34 forms an elastic body that can deform to generate elasticity. Under the action of an external force, the thin sheet 34 deforms to make the second positioning portion 8 float up and down relative to the base 2. The second one: as Figure 13 , the second positioning portion 8 is connected to the base 2 through an elastic body 35 such as an elastic sheet, a spring, or soft rubber. Under the action of the elastic body 35, the second positioning portion 8 can float up and down relative to the base 2.

[0079] The second positioning portion 8 is elastically movably arranged. During the installation process of the mounting plate 5 and the base 2, the first positioning portion 7 pushes the second positioning portion 8 to float upward. Under the action of the thin sheet 34 and the elastic body 35, the second positioning portion 8 maintains the movement in the direction of mating with the first positioning portion 7 or maintains the tendency of mating and positioning. When there is a partial misalignment between the first limiting portion 12 and the locking portion 13 or the first limiting groove 33 and they cannot enter, the first positioning portion 7 pushes the second positioning portion 8 to float, changing the positions of the mounting plate 5 and the locking portion 13 or the first limiting groove 33, so that the first limiting portion 12 can be inserted into the locking portion 13 or the first positioning groove. This can avoid the situation where the first limiting portion 12 and the locking portion 13 or the first limiting groove 33 are misaligned and cannot cooperate when errors occur during the production and processing process, or when dust, hair and other dirt adhere to the base 2 and the mounting plate 5 during daily use, causing the dimensional changes of the mating positions on the base 2 and the mounting plate 5.

[0080] Furthermore, the second positioning portion 8 is elastically movably arranged. After pressing the lock catch 4, the released elastic force of the thin sheet 34 and the elastic body 35 pushes the mounting plate 5 and the wiper 3 away from the base 2 through the second positioning portion 8, so that when the wiper 3 and the mounting plate 5 cannot be separated from the base 2 due to gravity, the elastic force of the thin sheet 34 and the elastic body 35 can still realize the disassembly of the wiper 3. Embodiment 5

[0081] The difference between Embodiment 5 and Embodiments 1-4 is: specifically introduce the device for cleaning this cleaning tool.

[0082] In this embodiment, the cleaning tool is set as a rotary mop, and the rotary mop is paired with a mop bucket 36 for cleaning the wiper 3.

[0083] Specifically, the rotary mop includes a mop head 2' and a mop rod 1' that are rotatably connected. The mop head 2' is provided with a wiper 3. The installation and disassembly method of the wiper 3 adopts the method described in Embodiments 2-4. The mop bucket 36 includes a cleaning area 37, and a cleaning seat 38 is arranged in the cleaning area 37. During cleaning, the cleaning seat 38 passes through the installation slot 6 of the mounting plate 5 and supports under the mop head 2'. The mop rod 1' drives the mop head 2' and the wiper 3 to rotate and contact the water in the cleaning area 37 for cleaning; a dehydration bucket 39 is detachably connected above the mop bucket 36. A rotatable dehydration basket 40 is arranged in the dehydration bucket 39. The dehydration basket 40 forms a dehydration area 40'. The dehydration basket 40 is provided with a dehydration seat 41. During dehydration, the dehydration seat 41 passes through the installation slot 6 of the mounting plate 5 and supports under the mop head 2'. Both the mop head 2' and the wiper 3 are located in the space enclosed by the dehydration basket 40. The mop rod 1' drives the mop head 2' and the wiper 3 to rotate for dehydration. The water thrown out by the wiper 3 flows downward into the mop bucket 36 through the drainage holes in the dehydration basket 40 and the dehydration bucket 39.

[0084] Preferably, the cleaning area 37 and the dehydration area 40' are arranged horizontally, and the height of the dehydration area 40' is higher than that of the cleaning area 37, so that the wiping object 3 contacts water and is cleaned in the lower cleaning area 37, and is dehydrated away from water in the higher dehydration area 40'.

[0085] In this embodiment, a cleaning brush 42 is provided on one side of the dehydration bucket 39 in the cleaning area 37. When the wiping object 3 rotates and is cleaned in the cleaning area 37, it is opened by centrifugal force, and the outer end of the wiping object 3 contacts the cleaning brush 42 for cleaning. The cleaning brush 42 improves the cleaning effect of the wiping object 3 by brushing. Specifically, a fixing hole 43 is provided at the bottom of the dehydration bucket 39, a fixing shaft 44 is provided at the end of the cleaning brush 42, and the fixing shaft 44 enters the fixing hole 43 upward for installation. After installation, the cleaning brush 42 and the fixing shaft 44 can rotate in the fixing hole 43. During cleaning, the wiping object 3 rotates and contacts the cleaning brush 42 and drives the cleaning brush 42 to rotate, and the rotation direction of the cleaning brush 42 is opposite to that of the wiping object 3.

[0086] Preferably, the fixing hole 43 penetrates up and down, and a through hole is provided in the center of the fixing shaft 44. The dehydration bucket 39 and the mop bucket 36 are connected through the fixing hole 43 and the hole in the fixing shaft 44. The water generated by the dehydration of the wiping object 3 can be discharged into the mop bucket 36 through the fixing hole 43 and the fixing shaft 44.

[0087] In this embodiment, the dehydration bucket 39 is detachably and fixedly installed on the mop bucket 36 through a button 45. Specifically, a reinforcing ring 46 is installed at the mouth of the mop bucket 36. The reinforcing ring 46 increases the strength of the mouth of the mop bucket 36 by increasing the wall thickness, avoiding inward deformation of the mouth of the mop bucket 36. Notches 47 are provided on both the mop bucket 36 and the reinforcing ring 46. A second limiting groove 48 is provided on the reinforcing ring 46 at the position corresponding to the notch 47. A boss 49 is provided on the side wall of the dehydration bucket 39, and a button 45 is provided in the boss 49. A buckle 50 cooperating with the second limiting groove 48 is provided on the button 45. By moving the button 45, the cooperation state between the buckle 50 and the second limiting groove 48 is changed to fix and disassemble the dehydration bucket 39.

[0088] Preferably, buttons 45 are provided on both opposite sides of the dehydration bucket 39, and notches 47 and second limiting grooves 48 are also provided on both opposite sides of the mop bucket 36 and the reinforcing ring 46. Both sides of the dehydration bucket 39 are fixedly connected to the mop bucket 36 through buttons 45 at the same time.

[0089] In this embodiment, the buckle 50 cooperates with the second limiting groove 48 to realize the up and down limitation of the dehydrating bucket 39 and the mop bucket 36. A third limiting groove 51 is further provided on the reinforcing ring 46, and a third limiting portion 52 is further provided on the boss 49. The notch 47 opens upward. When the dehydrating bucket 39 is installed, it enters the mop bucket 36 downward, and the boss 49 enters the notch 47 downward. The notch 47 forms a support for the boss 49. A support seat 53 is further provided on the mop bucket 36, and the bottom of the dehydrating bucket 39 is simultaneously supported above the support seat 53. The third limiting portion 52 enters the third limiting groove 51 downward to prevent the dehydrating bucket 39 from shaking relative to the mop bucket 36. The dehydrating bucket 39 continues to move downward until the buckle 50 of the button 45 enters the second limiting groove 48 to be fixed, and the installation of the dehydrating bucket 39 is completed. When disassembling the dehydrating bucket 39, only need to press the button 45 simultaneously to make the buckle 50 disengage from the second limiting groove 48, and then lift the dehydrating bucket 39 upward to complete the disassembly, so that the mop bucket 36, the dehydrating bucket 39 and the cleaning brush 42 can be cleaned respectively.

[0090] Preferably, a handle 54 is further provided on the mop bucket 36. Specifically, there is a sandwich layer 55 between the mop bucket 36 and the reinforcing ring 46 or inside the reinforcing ring 46. The rotating shaft 56 of the handle 54 passes through the mop bucket 36 inward to achieve a rotating connection. A stop block 57 is provided on the rotating shaft 56 at the position of the sandwich layer 55. The stop block 57 has a length, and there is an included angle between the length of the stop block 57 and the handle 54. During the process of the handle 54 rotating relative to the mop bucket 36, the stop block 57 rotates along with it until the handle 54 rotates to a position perpendicular to the mouth of the mop bucket 36, and the stop block 57 abuts and supports against the mop bucket 36 or the reinforcing ring 46 to prevent the handle 54 from continuing to rotate. In this embodiment, the stop block 57 is perpendicular to the handle 54.

[0091] A water pouring port 58 is provided on one side of the mop bucket 36 in the cleaning area 37, and a sealing plug 59 is arranged on the water pouring port 58. In this embodiment, the handle 54 is restricted to rotate within the range close to the dehydrating bucket 39, which is convenient for controlling the handle 54 with one hand and tilting the mop bucket 36 with the other hand to make the position of the water pouring port 58 at a lower position for convenient pouring of water.

[0092] Preferably, a brush 60 is detachably installed on the outer side of the dehydrating bucket 39 by magnetic attraction, and the brush 60 is used for brushing the mop bucket 36 and the dehydrating bucket 39.

[0093] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
