Description

[0001] This application is a divisional application. The original application was filed on April 10, 2025, with application number 202520670072.0 and invention titled "A cleaning tool with a quick-release cleaning head". Technical Field

[0002] This utility model relates to the field of cleaning tools, specifically to a cleaning tool with a quick-release cleaning head. Background Technology

[0003] Cleaning tools are widely used in daily life, and mops are an indispensable cleaning tool. They mainly use the cotton strips at the bottom of the mop head to wipe the floor and absorb dirt or liquids to clean the floor.

[0004] To facilitate changing the cleaning material, existing spin mops typically have a cotton strip fixed to a disc, with the mop head having an open cavity at the bottom. The disc is tightly fitted to the inner wall of the mop head. When removing the cleaning material, it is generally necessary to pull the cleaning material and the mop head together to remove the cleaning material. Although consumers have thought of using their feet to step on the cleaning material and pull the mop handle upwards to remove the cleaning material without getting their hands dirty, the dirty water and stains on the cleaning material can still easily soil their shoes.

[0005] Existing spin mops can only be used with special cotton strips and cannot be used with other cleaning heads or brush heads, making their floor cleaning function relatively limited.

[0006] Therefore, there is still much room for improvement in the installation and removal structure of the cleaning head of cleaning tools. Utility Model Content

[0007] One objective of this invention is to provide a cleaning tool with a quick-release cleaning head that solves the aforementioned problems.

[0008] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions:

[0009] A cleaning tool with a quick-release cleaning head includes a handle and a base. A cleaning head is detachably mounted on the base. The cleaning head includes a mounting plate and a cleaning component. The base has a latch, and the mounting plate has a locking part for locking the latch. A positioning mechanism is also provided between the base and the mounting plate. The positioning mechanism includes a first positioning part and a second positioning part. The first positioning part is located on the mounting plate, and the second positioning part is located on the base. When the latch locks the mounting plate, the first positioning part and the second positioning part engage, fixing the mounting plate to the base. The latch can be moved to remove the mounting plate from the base. The locking mechanism achieves upper and lower limit positioning between the base and the mounting plate, allowing for a secure connection even when the outer periphery of the mounting plate is not tightly fitted to or does not contact the inner wall of the base. The mounting plate utilizes the movement of the locking mechanism to limit and fix the base and mounting plate during installation and removal, enabling disassembly without contacting the cleaning head – a more hygienic and hands-free process. The positioning mechanism positions the mounting plate and base at a height where the locking mechanism can engage with the mounting plate, preventing the mounting plate from wobbling and avoiding misalignment between the locking mechanism and the mounting plate. The positioning mechanism also prevents the cleaning head from rotating relative to the base.

[0010] Preferably, the cleaning component is a wiping material or brush bristles. A mounting plate is provided on the wiping material in the form of a mop, sponge, or cotton thread, or on a brush head or broom head made of bristles. The detachable connection between the mounting plate and the base allows for the use of different types of cleaning tools with detachable cleaning heads. Furthermore, different types of cleaning heads can be attached to the base, allowing the cleaning tool to be switched between different types of mops, cleaning brushes, or brooms. Users can freely switch between these functions according to different needs, thereby expanding the cleaning range and methods of the cleaning tool.

[0011] Preferably, the first positioning part and / or the second positioning part are raised bosses, and the latch locks the mounting plate, supporting the mounting plate on the positioning mechanism. When the mounting plate is installed with the base, the mounting plate is prevented from rotating relative to the base by the support of the positioning mechanism.

[0012] Preferably, the mounting plate is provided with a circular or equilateral polygonal mounting groove, and the lower end of the latch is provided with a first limiting part, which enters the mounting groove and cooperates with the locking part to fix the mounting plate. The circular or equilateral polygonal mounting groove allows the mounting plate to be fixed with the first limiting part along different directions or different sides, simplifying the alignment process during mounting plate installation.

[0013] Preferably, the first positioning part is a circular or equilateral arrangement of multiple teeth, and the second positioning part is provided with several inserts; or the second positioning part is a circular or equilateral arrangement of multiple teeth, and the first positioning part is provided with several inserts. When the mounting plate is installed on the base, the inserts can cooperate with any of the teeth to limit the relative rotation of the mounting plate and the base. The latch can limit the mounting plate at any angle with the mounting groove or locking part. On this basis, the multiple teeth evenly arranged on the mounting plate allow the latch and the two positioning parts to simultaneously limit the vertical and circumferential directions of the mounting plate when the mounting plate is engaged with the mop head at any angle. The cooperation of the teeth and the inserts, in addition to limiting the circumferential direction of the mounting plate, can also form a support between the top of the mounting plate and the base, so that the first limiting part is at a relative height that can be inserted into the first locking part. This can reduce the clearance between the first limiting part and the locking part. Even if there is zero clearance between the first limiting part and the locking part in the vertical direction, the support of the teeth and the inserts can still allow the first limiting part to enter the locking part, thereby reducing the vertical swaying of the mounting plate.

[0014] Preferably, the second positioning part is elastically and movably connected to the base, allowing the second positioning part to float and engage with the first positioning part. When there is a partial misalignment between the first limiting part and the locking part or the first limiting groove, preventing them from entering, the first positioning part pushes the second positioning part to float, changing the position of the mounting plate and the locking part or the first limiting groove. This allows the first limiting part to be inserted into the locking part or the first positioning groove, preventing misalignment and inability to engage when errors occur during manufacturing or when dust, hair, or other contaminants adhere to the base and mounting plate during daily use, causing changes in the dimensions of the mating positions on the base and mounting plate.

[0015] Preferably, an elastic body is provided between the second positioning part and the base. When the latch and the locking part are released, the elastic force of the elastic body pushes the mounting plate to separate from the base. This allows the cleaning head to be disassembled even when the cleaning head and the mounting plate cannot detach from the base due to gravity, thanks to the elastic force of the sheet and the elastic body.

[0016] Preferably, the sides of any of the teeth and any of the inserts are set as inclined surfaces. When the mounting plate is installed, the teeth and the inserts automatically adjust to the meshing position through the cooperation of the inclined surfaces. The positioning mechanism and the first limiting part work together to clamp the mounting plate from top to bottom. When the cleaning head is installed, if the mounting plate and the base are not aligned at the position and angle where the teeth and the inserts are completely misaligned and meshed, pressing the base or mounting plate up and down will cause the base or mounting plate to automatically rotate along the inclined surface to the position and angle where the teeth and the inserts are completely misaligned and meshed. There is no need to rotate the base or mounting plate horizontally to adjust the limiting angle, making the installation of the cleaning head more convenient. At the same time, the inclined surface of the teeth and the inserts can cooperate with the latch and locking part to adjust the meshing clearance and clamping force between the latch and the upper stop.

[0017] Preferably, an upper stop is provided above the locking part, and the first limiting part can be inserted into any position of the locking part, providing support for the upper stop. The locking part and upper stop allow the latch to engage with the locking part at any angle and position, eliminating the need for the mounting plate to be deliberately adjusted to a preset angle for locking during cleaning head installation. This makes installation of the cleaning head more convenient and eliminates the need for alignment. Furthermore, the locking part prevents contact between the locking part located below the mounting plate and the ground, thus avoiding wear and tear.

[0018] Preferably, a lower stop is provided below the locking part, and the mounting plate has multiple tufting holes circumferentially. A cleaning component is fixed in each tufting hole. The cleaning component is a wiping material, which includes a wiping section and a tufting section. The wiping section extends radially outward along the mounting plate, and the tufting section extends towards the center of the mounting plate. The length of the wiping section is greater than the length of the tufting section. The lower stop prevents the tufting section from entering the mounting groove or the locking part. If the tufting section enters the mounting groove or the locking part, the latch may easily clamp the tufting section in the locking part. Furthermore, due to the influence of the tufting section, the latch may not be able to insert into the locking part to cooperate with the upper stop for positioning, thus preventing the wiping material from being installed.

[0019] Preferably, the width of the lower stop is not less than the length of the hair-planting segment, or a groove is provided between the hair-planting hole and the lower stop, with at least a portion of the hair-planting segment entering the groove, thus shortening the overlap length between the hair-planting segment and the lower stop. Since existing hair-planting processes struggle to shorten the length of the hair-planting segment, the width and shape of the lower stop need to be adjusted to prevent the hair-planting segment from entering the mounting groove and locking part.

[0020] Preferably, the latch and / or the upper stop block are provided with guide surfaces. When the base is aligned with the mounting plate, the first limiting part overlaps with the upper stop block. Pressing the handle downwards guides the latch to move towards the center of the base until the first limiting part is misaligned with the upper stop block. The elastic force of the first elastic element causes the first limiting part to insert into the locking part. The guide surface allows the cleaning head to be placed flat on the ground. By holding the handle and pressing downwards, the latch automatically moves horizontally under the upward and downward pressure of the mounting plate, thus enabling the cleaning head to be installed. During installation, there is no need to manually move the latch, making it more convenient to use.

[0021] The advantages of this utility model are:

[0022] The existing mounting plate and the inner wall of the base are fixed by a tight fit or snap-fit. The setting of the locking and positioning mechanism means that even if the mounting plate and the inner wall of the base are only in contact or not in contact, the movement of the locking can still limit the installation and release the limit between the base and the mounting plate. Disassembly can be completed without contacting the base, so as to achieve a more hygienic and clean disassembly of the cleaning head without getting your hands dirty.

[0023] The mounting plate and base are detachably connected to different types of cleaning heads, allowing different types of cleaning tools to be used with detachable cleaning heads. At the same time, different types of cleaning heads can be attached to the base, allowing the cleaning tools to be switched to different types, thereby expanding the cleaning range and methods of the cleaning tools.

[0024] The cooperation between the first positioning part and the second positioning part can prevent the mounting plate from rotating relative to the base. When the base and the mounting plate are circular, the latch can cooperate with the mounting plate at any angle and position. The first positioning part and the second positioning part can also cooperate at any angle and position. During the installation of the cleaning head, the mounting plate does not need to be deliberately adjusted to the preset limit angle, so that the installation of the cleaning head does not need to be aligned, which is more convenient. The cooperation between the first positioning part and the second positioning part, in addition to limiting the circumferential position of the mounting plate, can also form a support between the top of the mounting plate and the base, so that the first limiting part is at a relative height that can be inserted into the first locking part. This can reduce the clearance between the first limiting part and the locking part. Even if there is zero clearance between the first limiting part and the locking part in the vertical direction, the support of the second positioning part and the second positioning part can still allow the first limiting part to enter the locking part, thereby reducing the vertical swaying of the mounting plate.

[0044] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0045] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0046] like Figure 1-18 A cleaning tool with a quick-release cleaning head includes a handle 1 and a base 2. The cleaning head is detachably mounted on the base 2. The cleaning head includes a mounting plate 5 and a cleaning component. The base 2 is provided with a latch 4. The mounting plate 5 is provided with a locking part 13 for the latch 4 to be inserted. A positioning mechanism is also provided between the base 2 and the mounting plate 5. The positioning mechanism includes a first positioning part 7 and a second positioning part 8. The first positioning part 7 is disposed on the mounting plate 5, and the second positioning part 8 is disposed on the base 2. When the latch 4 locks the mounting plate 5, the first positioning part 7 and the second positioning part 8 are engaged, fixing the mounting plate 5 to the base 2. The latch 4 can be moved to remove the mounting plate 5 from the base 2. Example 1

[0047] In this embodiment, the cleaning tool is set as a mop, and the cleaning components are set as wiping materials 3 in the form of mop 9, cotton wool, cotton thread, etc. Since the wiping materials 3 of different materials have different material properties, they have their own advantages and disadvantages in terms of water absorption, cleaning power, weight, cost, etc. With the setting of the lock 4, the user can freely choose different materials of wiping materials 3 according to different usage scenarios.

[0048] In existing technologies, the methods for installing and removing wiping materials 3 differ depending on the material, such as... Figure 9Mop 9 is typically detachably connected to the plush side of the back of mop 9 via Velcro on the base 2, eliminating the need for a mounting plate 5 on mop 9. Similarly, sponge wipes are typically detachably connected to the base via a mounting plate that is plugged in or snapped into place. Cotton thread wipes are typically secured to a mounting plate to form a single unit, and then detachably connected to the base via the mounting plate. Furthermore, the shapes of the wipes 3 vary depending on the material. For example, mop 9 and sponge wipes are generally long strips or sheets, and their tops require support from the base 2 or mounting plate 5 for floor cleaning. Cotton thread wipes are generally disc-shaped, with the middle supported by the base 2 or mounting plate 5, while the outer edges are generally not supported by the base 2 or mounting plate 5.

[0049] To accommodate different wiping materials, such as Figure 9-10 In this embodiment, different types of wiping materials 3 are paired with different mounting plates 5, and each mounting plate 5 is detachably mounted to the base 2 through the same structure.

[0050] Based on the above structure, the cleaning component can also be replaced with bristles, so that the cleaning head forms a brush head or broom head 10, such as... Figure 11 Simply by fixing the bristles to the mounting plate 5 with the above-mentioned installation and disassembly structure, the cleaning tool can be replaced from a mop to a cleaning brush or broom, further expanding the cleaning types of cleaning tools. Example 2

[0051] The difference between this embodiment and embodiment 1 is that this embodiment uses a mop with cotton thread wiping material 3 installed as an example to illustrate the specific structure.

[0052] In this embodiment, the cleaning tool is a rotary mop with a cotton wiping material 3 attached. The mop handle 1' and mop head 2' on the rotary mop form the handle 1 and base 2 of the cleaning tool, respectively. The rotary mop in this embodiment is the same as that in the prior art, and is supported by the mop head 2' in the mop bucket 36 to rotate for cleaning and dehydration. How to drive the mop head 2' to rotate and how the mop head 2' cleans and dehydrates are not the inventive points of this embodiment, and will not be described in detail here.

[0053] like Figure 4-6In this embodiment, the overall shape or internal cavity shape of the base 2 is circular, and the overall shape of the mounting plate 5 is also circular. Based on the circular structure, the mounting plate 5 is vertically limited by the latch 4, so that the wiping material 3 can be disassembled without contacting it. The positioning mechanism supports the mop head 2' and the mounting plate 5 vertically and prevents relative rotation between the mop head 2' and the mounting plate 5, which is suitable for synchronously rotating the wiping material 3 for cleaning and dehydration during the rotation of the mop head 2'. During the installation and disassembly of the wiping material 3, the positioning mechanism automatically limits and releases the latch 4 when it is in motion or released, without the need to separately control the cooperation state of the two sets of limiting structures. Of course, the latch 4 and the positioning mechanism can be set as the same mechanism or different mechanisms. When the latch 4 and the positioning mechanism are set as the same mechanism, the latch 4 has both the functions of vertical limiting and support positioning, that is, the positioning mechanism in this mode is the latch 4.

[0054] The existing mop head 2' and mounting plate 5 are also designed to be circular, such as... Figure 7 The existing mop head 2' and mounting plate 5 are fixed by a tight fit. The upper and lower and circumferential limits are achieved by the tight fit between the mop head 2' and the mounting plate 5. When removing the wiping object 3, it is necessary to pull the wiping object 3 and the mop head 2' to forcefully separate them. The hands or feet need to come into contact with the wiping object 3, which is not a very hygienic operation. On the other hand, the structure with switch control such as a plug can remove the wiping object 3 without getting your hands dirty. However, 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 with the hole or groove on the mounting plate 5. Precise alignment is required when installing the mop head 2'.

[0055] Based on the existing structure, the latch 4 used in this embodiment can limit the vertical movement of the mounting plate 5 at any angle. In addition to supporting and positioning the mop head 2' and the mounting plate 5, the positioning mechanism can also limit the circumferential movement of the mop head 2' and the mounting plate 5 at any angle. Installation of the wiping material 3 can be achieved without precise alignment, and removal of the wiping material 3 only requires manipulating the latch 4, without contacting the wiping material 3. It should be noted that in this embodiment, the vertical, horizontal, or lateral directions are referenced to the state where the mop handle 1' and the mop head 2' are perpendicular and the mop head 2' is placed horizontally on the ground. Figure 2-3 As shown, the vertical direction is the extension direction of the mop handle 1', and the horizontal or transverse direction is the plane direction where the mop head 2' is located. In this embodiment, the angle between the mop head 2' and the mounting plate 5 refers to any angle at which the mop head 2' and the mounting plate 5 rotate on the plane when they are in a parallel position. No matter how much the mounting plate 5 rotates on the plane, the latch 4 can cooperate with the mounting plate 5 at any angle to limit its vertical movement, thereby reducing the installation and alignment steps between the latch 4 and the mounting plate 5.

[0056] To simplify the structure of the mop head 2' and the mounting plate 5, this embodiment sets the mounting plate 5 as an annular shape. The central cavity of the mounting plate 5 forms a mounting groove 6. The latch 4 can move radially along the mop head 2'. The latch 4 is provided with a first elastic element 11. The elastic force of the first elastic element 11 keeps the latch 4 moving towards the periphery of the mop head 2'. The first limiting part 12 on the latch 4 can be supported under the mounting plate 5. When the wiping material 3 is removed, the latch 4 moves towards the center of the mop head 2', and the mounting plate 5 disengages from the support of the first limiting part 12 and separates downward from the mop head 2'. By using the central cavity of the mounting plate 5 for the movement and limiting of the latch 4, the thickness of the mop head 2' and the mounting plate 5 can be reduced.

[0057] Preferably, the central cavity of the mounting plate 5 is a circular hole, and the first limiting part 12 at the lower end of the latch 4 is a hook or pin. The first limiting part 12 passes downward through the central cavity and is formed below the mounting plate 5. In this structure, the circular hole forms a mounting groove 6, and the first limiting part 12 passes through the mounting groove 6 and cooperates with any edge position of the bottom surface of the mounting plate 5 for limiting. This cooperation position of the mounting plate 5 forms a locking part 13.

[0058] Furthermore, a groove communicating with the circular hole can also be provided on the inner side of the mounting plate 5, and the first limiting part 12 is inserted into the mounting groove 6 and cooperates with the groove on the mounting plate 5 for limiting, such as... Figure 2 The groove can be the settlement surface of the bottom of the mounting plate 5, such as... Figure 3 Alternatively, it can be a groove extending laterally from the edge of a circular hole. Specifically, a locking part 13 is provided on the inner side of the mounting plate 5. The locking part 13 communicates with the central cavity of the mounting plate 5 to form the mounting groove 6. It can be understood that the locking part 13 is part of the mounting groove 6. An upper stop block 14 is provided above the locking part 13. The first limiting part 12 can be inserted into any position of the locking part 13 and support the upper stop block 14 above it. With the setting of the locking part 13 and the upper stop block 14, the first limiting part 12 can cooperate with the locking part 13 at any angle and position for positioning. During the installation of the wiping material 3, the mounting plate 5 does not need to be deliberately adjusted to a preset angle that can be limited by the first limiting part 12, so that the installation of the wiping material 3 does not need to be aligned, which is more convenient. The setting of the locking part 13 prevents the limit switch located below the mounting plate 5 from contacting the ground and causing ground wear.

[0059] Preferably, the mounting slot 6 can also be set as an equilateral polygon, with a locking part 13 provided on any side of the polygon, and the first limiting part 12 can cooperate with the locking part 13 on any side for positioning.

[0060] In this embodiment, the wiping material 3 has multiple circumferentially arranged bristle holes 15 on the mounting plate 5. Each bristle hole 15 has a soft, absorbent wiping material unit such as a cloth strip or cotton thread fixed in it. The inner end of the wiping material 3 in the length direction is fixed in the bristle hole 15 and extends out of the bristle hole 15 to form a bristle section 16. The part of the wiping material 3 located outside the bristle hole 15 can be stretched outward along the radial direction of the mounting plate 5 when the mop head 2' rotates, and extends out of the outer periphery of the mop head 2' to expand the mopping area, thereby forming a wiping section 17 for cleaning the floor. When the rotating mop is in a stationary and suspended position, the outer part of the wiping section 17 naturally falls below the mop head 2' under gravity, reducing the area of ​​the horizontal cross section so that it can enter the mop bucket 36 for washing and dehydration.

[0061] Preferably, the length of the wiping segment 17 is greater than the length of the hair-planting segment 16.

[0062] Preferably, the edge of the hair implantation hole 15 is provided with a serrated protrusion 18, which can be inserted into the wiping material 3 to prevent the wiping material 3 from falling out of the hair implantation hole 15.

[0063] Since the existing cotton thread fixing process makes it difficult to remove the hair grafting section 16, in order to prevent the hair grafting section 16 from entering the mounting groove 6 and obstructing the connection between the latch 4 and the mounting plate 5, in this embodiment, a lower stop block 19 is provided below the locking part 13. The lower stop block 19 extends downward or toward the center area of ​​the mounting plate 5, and the lower stop block 19 is used to block the hair grafting section 16 from entering the mounting groove 6.

[0064] The lower stop 19 can block the hair-planting section 16 in two ways. First, the width of the lower stop 19 is not less than the length of the hair-planting section 16. The width of the lower stop 19 is the distance that the lower stop 19 extends towards the center of the mounting plate 5. By widening the lower stop 19, the end of the hair-planting section 16 is prevented from obstructing the movement of the latch 4. Second, a groove 20 is provided between the hair-planting hole 15 and the lower stop 19. After the hair-planting section 16 is pressed, its end is inserted into the groove 20, or a part of the hair-planting section 16 is pressed into the groove 20, shortening the overlap length between the end of the hair-planting section 16 and the lower stop 19. The groove 20 can be structured by extending the outer edge of the lower stop 19 downwards to form a step, creating a height difference between the step and the hair-planting hole 15, with the space formed by this height difference being the groove 20. Alternatively, the groove 20 can be structured by extending the wall of the hair-planting hole 15 downwards to form a frustum, based on the step on the lower stop 19. The recessed space formed between the frustum and the step forms the groove 20. The combination of the frustum and the groove 20 extends the length that the hair-planting section 16 needs to travel to enter the mounting groove 6, thereby preventing the hair-planting hole 15 from obstructing the latch 4. Of course, in both of the above methods, the width of the lower stop 19 and the groove 20 can be extended simultaneously to further prevent the end of the hair-planting section 16 from obstructing the latch 4.

[0065] In this embodiment, the width of the lower stop 19 is greater than the width of the upper stop 14.

[0066] like Figure 5-6 8. The structure of the positioning mechanism is described in detail. In this embodiment, the positioning mechanism includes a first positioning part 7 and a second positioning part 8. The first positioning part 7 and / or the second positioning part 8 are raised bosses. The latch 4 locks the mounting plate 5 and supports the mounting plate 5 on the positioning mechanism. The first positioning part 7 is configured as a plurality of teeth 21 arranged in a circle. The second positioning part 8 is configured as a plurality of inserts 23. The teeth 21 and the inserts 23 cooperate for positioning. Specifically, the first positioning part 7 is configured as a face gear 7' on the top surface of the mounting plate 5. The face gear 7' has multiple ring-shaped teeth 21, and a slot 22 is formed between any two adjacent teeth 21. The second positioning part 8 is configured as several inserts 23 that fit into the slots 22. When the mounting plate 5 and the mop head 2' are aligned vertically, the inserts 23 are inserted into the slots 22, or the teeth 21 and the inserts 23 are staggered and meshed for positioning. The mounting plate 5 is supported and positioned vertically in both directions through the cooperation of the inserts 23 and the slots 22, and the first limiting part 12. At the same time, the teeth 21 extend upward and the inserts 23 extend downward. The meshing of the teeth 21 and the inserts 23 or the insertion of the inserts 23 into the slots 22 prevents the mounted plate 5 from rotating relative to the mop head 2' after installation. Thus, the mounting plate 5 is vertically and circumferentially limited on the mop head 2', allowing the wiping material 3 to rotate synchronously with the mop head 2' for cleaning and dehydration. In other embodiments, the first positioning part 7 may be configured as a plurality of inserts 23, and the second positioning part 8 may be configured as a plurality of teeth 21 arranged in a circle. When the mounting plate 5 and the mop head 2' are in the mounting position, the inserts 23 may engage with any tooth 21 or be inserted into the slot 22 between any two teeth 21, thereby preventing the mounting plate 5 from rotating relative to the mop head 2'.

[0067] Preferably, the face gear 7' is located on the edge of the upper stop block 14, between the mounting groove 6 and the bristle hole 15. The locking part 13 is located below the face gear 7', and the centers of the locking part 13 and the face gear 7' are on the same straight line. There is no partition inside the locking part 13. The face gear 7' and the insert block 23 provide circumferential positioning. When the wiping material 3 is installed, the mop head 2' and the mounting plate 5 are aligned vertically. If one of the mounting plate 5 and the mop head 2' is stationary, the other can still engage with the first limiting part 12 and the locking part 13 even when rotated to any angle along its plane. The insert block 23 can still engage with the teeth 21 at the corresponding angle and position for positioning. Of course, the angle at which the insert block 23 and the face gear 7' can engage is related to the number of teeth 21. The more teeth 21 there are, the more angles the insert block 23 can engage.

[0068] In this embodiment, there are two latches 4, which are mirror images of the mop handle 1'. The wiping material 3 is removed by pressing the two latches 4 simultaneously. The insert 23 is set in the annular area between the two latches 4. The number of inserts 23 can be one or multiple segments of rack. The inserts 23 and latches 4 are staggered, which can provide support for the top of the mounting plate 5 before and after installation. Even if there is a pre-set installation gap between the mounting plate 5 and the mop head 2' and latches 4, the support of the inserts 23 and the face gear 7' can reduce the shaking of the mounting plate 5.

[0069] Preferably, the sides of any tooth 21 and any insert 23 are set as inclined surfaces. During the installation of the wiping material 3, when the tooth 21 and the insert 23 are not at a fully engaged angle, by applying force in the up and down direction, the tooth 21 and the insert 23 can adjust their angle and position along the inclined surface to achieve a fully engaged state. To avoid the tooth 21 and the insert 23 being in a state where their ends are abutting and unable to engage, the ends of the tooth 21 and the insert 23 can be set as pointed tips or arc segments, thereby expanding the angle range of the tooth 21 and the insert 23 automatically adjusting their engagement state. This eliminates the need for visual alignment and manual adjustment of the position of the mop head 2' and the mounting plate 5, making the installation process of the wiping material 3 more convenient.

[0070] Preferably, the latch 4 has a second limiting part 24 above the first limiting part 12. A groove for the upper stop 14 to be inserted is formed between the first limiting part 12 and the second limiting part 24. When the tooth 21 and the insert 23 are engaged, the bottom surface of the second limiting part 24 is in contact with the top surface of the upper stop 14, so that the first limiting part 12 and the locking part 13 can move smoothly even when there is zero installation clearance between them. In this embodiment, the slope of the tooth 21 and the insert 23 is the same. Even when there is zero installation clearance between the first limiting part 12 and the locking part 13, or when the first limiting part 12, the mounting plate 5, the tooth 21, or the insert 23 are worn due to use, the position can still be adjusted by the slope of the tooth 21 and the insert 23 so that the first limiting part 12 can still be positioned in the locking part 13.

[0071] In addition to pressing the latch 4 first to misalign the first limiting part 12 and the upper stop 14, and then inserting the first limiting part 12 into the locking part 13, the installation of the wiping material 3 can also be done without pressing the latch 4. Instead, by applying downward force to the mop head 2' or mop handle 1', the latch 4 is automatically moved to misalign with the upper stop 14 and enters the locking part 13. Specifically, the lower end of the first limiting part 12 has a guide surface 25. When the mounting plate 5 is placed in the preset position of the mop head 2', the guide surface 25 contacts the upper stop 14, and the mop head 2' is subjected to a downward force. The latch 4 abuts against the upper stop 14 at the position of the guide surface 25. Under the action of the guide surface 25, the upper stop 14 pushes the latch 4 to move until it moves to a position where the inner sides of the first limiting part 12 and the upper stop 14 are exactly aligned or separated. Under the action of the first elastic member 11, the first limiting part 12 is inserted into the locking part 13 for positioning. Of course, in order to make the movement of the latch 4 smoother, a guide surface 25 can also be provided at the top edge of the upper stop 14. Preferably, both the first limiting part 12 and the guide surface 25 on the upper stop 14 are inclined surfaces.

[0072] Preferably, the inner and outer sides of the face gear 7' are respectively provided with an inner baffle 26 and an outer baffle 27. The inner baffle 26 and the outer baffle 27 prevent the insertion block 23 from moving horizontally. The height of the inner baffle 26 and the outer baffle 27 is higher than the height of the tooth 21, so as to avoid the tip of the tooth 21 being bumped and damaged, which would affect the installation and disassembly of the mounting plate 5.

[0073] In this embodiment, the latch 4 is horizontally movable and mounted on the mop head 2'. Specifically, the mop head 2' has a vertically penetrating switch groove 28. The latch 4 includes an upper cover 29 and a lower cover 30, which are located on the upper and lower sides of the switch groove 28, respectively. The upper cover 29 and the lower cover 30 are fixedly connected as a whole through the switch groove 28. Pushing the upper cover 29 along the outer surface of the mop head 2' causes the latch 4 to slide horizontally along the switch groove 28. To limit the sliding direction of the latch 4, guide strips 31 extending into the switch groove 28 are provided on both sides of the switch groove 28, and guide grooves 32 are provided on the latch 4. When the latch 4 is installed, the guide strips 31 are inserted into the guide grooves 32. The cooperation between the guide strips 31 and the guide grooves 32 serves to limit the upper and lower movement and guide the movement. The sliding direction limit of the latch 4 can also be set such that the dimensions of the upper cover 29 located at the upper end of the switch groove 28 and the lower cover 30 located at the lower end of the switch groove 28 are both larger than the dimensions of the switch groove 28. After the upper cover 29 and the lower cover 30 are installed as a whole, the connection between the upper cover 29 and the lower cover 30 clamps the edge of the switch groove 28 to achieve the upper and lower limit and the movement guide limit of the latch 4.

[0074] In this embodiment, as Figure 3The outer side of the mounting plate 5 and the inner side of the mop head 2' are only in contact or fit together, so that the mounting plate 5 can be separated from the mop head 2' by gravity after the locking buckle 4 moves to the contact limit position. In other embodiments, the mounting plate 5 can also be fixed to the bottom surface of the mop head 2', and the outer side of the mounting plate 5 and the inner side of the mop head 2' no longer contact each other. Since the mop head 2' and the mounting plate 5 are limited in the vertical and horizontal directions by the cooperation of the first limiting part 12 and the locking part 13, and the first positioning part 7 and the second positioning part 8, even if the enclosure of the inner side of the mop head 2' is lost, the mounting plate 5 will not rotate or shake. Moreover, without the obstruction of the inner side 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 that can be used with a mop cloth 9 or a sponge, or a brush or broom with bristles. Example 3

[0075] The difference between this embodiment and the above embodiment is that the base 2 and the mounting plate 5 are set as equilateral polygons.

[0076] Preferably, the base 2 is shaped as an equilateral triangle, square, regular hexagon, or other regular polygon. When any equilateral polygon is used, the latch 4 can be positioned by cooperating with any side of the polygon to simplify the alignment of the mounting plate 5 during installation. 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 downwardly extending side wall. The side wall and the top surface of the base 2 together form a mounting cavity. The mounting plate 5 enters the mounting cavity upward. Due to the obstruction and enclosure of the side wall, the mounting plate 5 cannot rotate relative to the base 2.

[0077] like Figure 9-11 In this embodiment, the base 2 and mounting plate 5 are illustrated using an equilateral triangle as an example. Specifically, the base 2 and mounting plate 5 are set as equilateral triangles with matching shapes. The outer side of the mounting plate 5 can fit against the side of the base 2 to prevent the mounting plate 5 from rotating relative to the base 2. A triangular mounting groove 6 is also provided in the center of the mounting plate 5. The base 2 is provided with a latch 4 at the position corresponding to the mounting groove 6. One side of the mounting plate 5 is provided with a first limiting groove 33 that communicates with the mounting groove 6. The first limiting part 12 on the latch 4 is inserted into the first limiting groove 33 to limit the mounting plate 5 vertically. The structure of the upper stop block 14 and the lower stop block 19 on the upper and lower sides of the latch 4 and the first limiting groove 33 is the same as in embodiment 2, and will not be described again in this embodiment.

[0078] Preferably, the mounting plate 5 is provided with a first limiting groove 33 on each side of the central mounting groove 6, and after the mounting plate 5 is rotated, the first limiting part 12 can be connected with the first limiting groove 33 on different sides.

[0079] In the above embodiments, regardless of the shape of the equilateral polygons used for 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 corresponding equilateral polygon shape, and a plurality of first limiting grooves 33 or locking parts 13 are provided on the side of the circular mounting groove 6.

[0080] Preferably, the top surface of the mounting plate 5 is provided with a first positioning part 7, and the base 2 is provided with a second positioning part 8 at a position other than the latch 4. The first positioning part 7 is provided with a plurality of teeth 21, and the second positioning part 8 is also provided with a plurality of inserts 23. When the mounting plate 5 is connected to the base 2, the teeth 21 and the inserts 23 engage in a staggered manner to provide support for the upper part of the mounting plate 5. Under the support and cooperation of the teeth 21 and the inserts 23, the first limiting part 12 and the first limiting groove 33 are at the same height, and the first limiting part 12 can smoothly enter the first limiting groove 33. The shapes of part 21 and insert 23 are the same as in embodiment 2, and will not be described again in this embodiment. There is a zero installation clearance fit between the first limiting part 12 and the first limiting groove 33, or the first limiting part 12, mounting plate 5, tooth 21 or insert 23 can still be adjusted in position by the inclined surface fit of tooth 21 and insert 23 after wear due to use, so that the first limiting part 12 can still enter the first limiting groove 33 for positioning. In addition, when the mounting plate 5 is not in contact with the side wall, the meshing of tooth 21 and insert 23 can prevent the mounting plate 5 from rotating relative to the base 2. Example 4

[0081] The difference between Embodiment 4 and Embodiments 2 and 3 lies in the structure of the second positioning part 8.

[0082] In embodiments 2 and 3, the first positioning part 7 is integrally formed with the mounting plate 5, and the second positioning part 8 is integrally formed with the base 2 and is rigidly connected to the base 2. In this embodiment, the second positioning part 8 is elastically connected to the base 2.

[0083] Specifically, the flexible movable connection structure can be adopted in the following two ways. The first way: such as... Figure 12 The second positioning part 8 is integrally formed with the base 2, and a thin sheet 34 is also integrally formed between the second positioning part 8 and the base 2. The thin sheet 34 forms a deformable elastic body. Under the action of external force, the thin sheet 34 deforms, causing the second positioning part 8 and the base 2 to float up and down. Second type: such as Figure 13 The second positioning part 8 is connected to the base 2 via an elastic body 35 such as a spring, a soft rubber, etc. Under the action of the elastic body 35, the second positioning part 8 can float up and down relative to the base 2.

[0084] The second positioning part 8 is flexibly movable. During the installation of the mounting plate 5 and the base 2, the first positioning part 7 pushes the second positioning part 8 to float upwards. Under the action of the thin sheet 34 and the elastic body 35, the second positioning part 8 maintains its movement in the direction of engagement with the first positioning part 7 or remains in a position of engagement. When there is a partial misalignment between the first limiting part 12 and the locking part 13 or the first limiting groove 33, preventing them from entering, the first positioning part 7 pushes the second positioning part 8 to float, changing the position of the mounting plate 5 and the locking part 13 or the first limiting groove 33. This allows the first limiting part 12 to be inserted into the locking part 13 or the first positioning groove, preventing misalignment and inability to engage when errors occur during production or when dust, hair, or other contaminants adhere to the base 2 and the mounting plate 5 during daily use, causing changes in the dimensions of the mating positions on the base 2 and the mounting plate 5.

[0085] Furthermore, the second positioning part 8 is elastically movable. After pressing the latch 4, the release force of the sheet 34 and the elastic body 35 pushes the mounting plate 5 and the wiping material 3 away from the base 2 through the second positioning part 8. So that even when the wiping material 3 and the mounting plate 5 cannot be removed from the base 2 due to gravity, the elastic force of the sheet 34 and the elastic body 35 can still achieve the disassembly of the wiping material 3. Example 5

[0086] The difference between Example 5 and Examples 1-4 is that Example 5 specifically describes the device used for cleaning this cleaning tool.

[0087] In this embodiment, the cleaning tool is set as a rotating mop, and the rotating mop is used with a mop bucket 36 to clean the wiping object 3.

[0088] Specifically, the rotary mop includes a rotatably connected mop head 2' and mop handle 1'. The mop head 2' is equipped with a wiping agent 3, which is installed and removed in the manner described in embodiments 2-4. The mop bucket 36 includes a cleaning area 37, within which a cleaning seat 38 is provided. During cleaning, the cleaning seat 38 passes through the mounting groove 6 of the mounting plate 5 and is supported below the mop head 2'. The mop handle 1' drives the mop head 2' and the wiping agent 3 to rotate and come into contact with the water in the cleaning area 37 for cleaning. The upper part of the mop bucket 36 is detachable. The device is connected to a spin-drying tub 39, which contains a rotatable spin-drying basket 40. The spin-drying basket 40 forms a spin-drying zone 40'. The spin-drying basket 40 is equipped with a spin-drying seat 41. During spin-drying, the spin-drying seat 41 passes through the mounting groove 6 of the mounting plate 5 and is supported below the mop head 2'. The mop head 2' and the wiping material 3 are both located within the space enclosed by the spin-drying basket 40. The mop handle 1' drives the mop head 2' and the wiping material 3 to rotate and spin-dry. The water spun out by the wiping material 3 flows downward into the mop bucket 36 through the drain holes in the spin-drying basket 40 and the spin-drying tub 39.

[0089] Preferably, the cleaning zone 37 and the dehydration zone 40' are arranged horizontally, and the height of the dehydration zone 40' is higher than the height of the cleaning zone 37, so that the wiping material 3 is cleaned in contact with water in the lower cleaning zone 37, and dehydrated away from water in the higher dehydration zone 40'.

[0090] In this embodiment, a cleaning brush 42 is provided on one side of the dehydration tub 39 located in the washing zone 37. When the wiping material 3 rotates and is washed in the washing zone 37, it is opened by centrifugal force, and the outer end of the wiping material 3 contacts the cleaning brush 42 for cleaning. The cleaning brush 42 improves the cleaning effect of the wiping material 3 by brushing. Specifically, a fixing hole 43 is provided at the bottom of the dehydration tub 39, and a fixing shaft 44 is provided at the end of the cleaning brush 42. The fixing shaft 44 is installed upward into the fixing hole 43. After installation, the cleaning brush 42 and the fixing shaft 44 can rotate in the fixing hole 43. During washing, the wiping material 3 rotates and contacts the cleaning brush 42, causing the cleaning brush 42 to rotate. The rotation direction of the cleaning brush 42 is opposite to the rotation direction of the wiping material 3.

[0091] Preferably, the fixing hole 43 extends vertically, and the fixing shaft 44 has a through hole in the center. The spin-drying tub 39 and the mop tub 36 are connected through the fixing hole 43 and the hole in the fixing shaft 44. The water generated by the spin-drying of the wiping material 3 can be discharged into the mop tub 36 through the fixing hole 43 and the fixing shaft 44.

[0092] In this embodiment, the spin-drying tub 39 is detachably and fixedly mounted on the mop tub 36 via a button 45. Specifically, a reinforcing ring 46 is installed at the opening of the mop tub 36. The reinforcing ring 46 increases the strength of the opening of the mop tub 36 by increasing the wall thickness, preventing the opening of the mop tub 36 from deforming inward. Both the mop tub 36 and the reinforcing ring 46 are provided with notches 47. The reinforcing ring 46 is provided with a second limiting groove 48 at the position corresponding to the notch 47. The side wall of the spin-drying tub 39 is provided with a boss 49. A button 45 is provided inside the boss 49. The button 45 is provided with a buckle 50 that cooperates with the second limiting groove 48. By moving the button 45, the cooperation state between the buckle 50 and the second limiting groove 48 is changed, so as to fix and remove the spin-drying tub 39.

[0093] Preferably, buttons 45 are provided on both sides of the spin-drying tub 39, and notches 47 and second limiting grooves 48 are also provided on both sides of the mop tub 36 and the reinforcing ring 46. The two sides of the spin-drying tub 39 are fixedly connected to the mop tub 36 through the buttons 45.

[0094] In this embodiment, the buckle 50 cooperates with the second limiting groove 48 to achieve the upper and lower limits of the spin-drying bucket 39 and the mop bucket 36. The reinforcing ring 46 is also provided with a third limiting groove 51, and the boss 49 is also provided with a third limiting part 52. The notch 47 opens upward. When the spin-drying bucket 39 is installed, it enters the mop bucket 36 downward. The boss 49 enters the notch 47 downward. The notch 47 provides support for the boss 49. The mop bucket 36 is also provided with a support seat 53. The bottom of the spin-drying bucket 39 is simultaneously supported above the support seat 53. The third limiting part 52 enters the third limiting groove 51 downward to prevent the spin-drying bucket 39 from shaking relative to the mop bucket 36. The spin-drying bucket 39 continues to move downward until the buckle 50 of the button 45 enters the second limiting groove 48 and is fixed. The installation of the spin-drying bucket 39 is completed. When disassembling the spin tub 39, simply press button 45 simultaneously to disengage the buckle 50 from the second limiting groove 48, and then lift the spin tub 39 upwards to complete the disassembly, thereby allowing the mop bucket 36, spin tub 39, and cleaning brush 42 to be cleaned separately.

[0095] Preferably, the mop bucket 36 is also provided with a handle 54. Specifically, a sandwich 55 is provided between the mop bucket 36 and the reinforcing ring 46 or within the reinforcing ring 46. The pivot 56 of the handle 54 passes inward through the mop bucket 36 to achieve a rotatable connection. A stop 57 is provided on the pivot 56 located at the sandwich 55. The stop 57 has a length, and the length of the stop 57 forms an angle with the handle 54. During the rotation of the handle 54 relative to the mop bucket 36, the stop 57 rotates along with it until the handle 54 rotates to a position perpendicular to the opening of the mop bucket 36. At this point, the stop 57 abuts against the mop bucket 36 or the reinforcing ring 46 to provide support and prevent the handle 54 from continuing to rotate. In this embodiment, the stop 57 is perpendicular to the handle 54.

[0096] The mop bucket 36 has a water outlet 58 on one side of the washing area 37, and a sealing plug 59 is provided on the water outlet 58. In this embodiment, the handle 54 is restricted to rotating within the range near the spin-drying bucket 39, so that one hand can control the handle 54 and the other hand can lift the mop bucket 36 to tilt, so that the water outlet 58 is in a low position for easy water pouring.

[0097] Preferably, a brush 60 is magnetically attached to the outside of the spin-dry tub 39, and the brush 60 is used to scrub the mop tub 36 and the spin-dry tub 39.

[0098] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
