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.

[0036] like Figures 1-15 A quick-release switch structure for wiping materials includes a mop handle 1 and a mop head 2. A wiping material 3 is detachably mounted on the mop head 2. The mop head 2 has a through-hole 4. An unlocking switch 5 is movably mounted on the switch hole 4. The unlocking switch 5 includes a hand control part 6 and an unlocking part 7, which are located on the upper and lower sides of the switch hole 4, respectively. The switch hole 4 has a limiting part 8. The hand control part 6 has a first limiting point 9, and the unlocking part 7 has a second limiting point 10. The first limiting point 9 and the second limiting point 10 cooperate with the limiting part 8 to movably suspend and fix the unlocking switch 5 on the switch hole 4. The wiping material 3 has a mounting plate 11. The unlocking switch 5 moves on the switch hole 4 to fix or unlock the mounting plate 11.

[0037] The rotating mop in this embodiment is the same as that in the prior art. It is supported by the mop head 2 and rotates in the mop bucket for cleaning and dehydration. The structure of how to drive the mop head 2 to rotate and how the mop head 2 cleans and dehydrates is not the inventive point of this embodiment, and will not be described in detail here.

[0038] In this embodiment, the unlocking switch 5 is movably mounted on the switch hole 4, and the unlocking part 7 is located in the direction corresponding to the mounting plate 11. The push-pull handle 6 moves the unlocking part 7 closer to or further away from the mounting plate 11, so that the wiping material 3 can be removed without contacting the unlocking part 7 and the wiping material 3. In other embodiments, such as... Figure 4 and 5 Alternatively, the unlocking switch 5 can be rotatably mounted on the switch hole 4. The rotating shaft on the unlocking switch 5 passes through the switch hole 4, and the unlocking part 7 protrudes outward from one side of the rotating shaft. Rotating the hand control part 6 drives the rotating shaft to rotate, adjusting the angle or position between the unlocking part 7 and the mounting plate 11, so as to remove the wiping material 3 without contacting the unlocking part 7 and the wiping material 3.

[0039] Regardless of whether the unlocking switch 5 uses a sliding or rotating connection, it is limited in its upper and lower positions by engaging with the switch hole 4 through the first limiting point 9 and the second limiting point 10. Specifically, as shown... Figure 6 The hand control part 6 and the unlocking part 7 can be manufactured in one piece. That is, the middle part of the unlocking switch 5 is provided with a groove 12. The size of the groove 12 is adapted to the switch hole 4. The two parts of the unlocking switch 5 located in the upper and lower directions of the groove 12 form the hand control part 6 and the unlocking part 7 respectively. During installation, the hand control part 6 or the unlocking part 7 can be pressed through the switch hole 4 so that the edge of the switch hole 4 is inserted into the groove 12. The part of the switch hole 4 wall inserted into the groove 12 forms a limiting part 8. The side walls in the upper and lower directions of the groove 12 form a first limiting point 9 and a second limiting point 10 respectively. In this way, the width of the second limiting point 10 can be set to be smaller than the width of the first limiting point 9, so that the second limiting point 10 can be pressed through the switch hole 4 from top to bottom.

[0040] Besides the one-piece molding method, the hand control unit 6 and the unlocking unit 7 can also be set as two separate parts, such as... Figure 7 and 8 The hand control unit 6 is located above the switch hole 4, and the unlocking unit 7 is located below the switch hole 4. The upper end of the unlocking unit 7 has a connecting section 13 that can pass through the switch hole 4. After passing through the switch hole 4, the connecting section 13 is fixedly connected to the hand control unit 6. After being fixedly connected, the hand control unit 6 and the unlocking unit 7 are located on the upper and lower sides of the switch hole 4 in a roughly fitted manner. The positions where the hand control unit 6 and the unlocking unit 7 are fitted with the edge of the switch hole 4 form a first limiting point 9, a second limiting point 10, and a limiting part 8, respectively. The connecting section 13 and the hand control unit 6 can be fixed by means of snap-fit, plug-in fastening, thread, screw, etc.

[0041] In this embodiment, the outer contours of both the mop head 2 and the mounting plate 11 are circular. The mounting plate 11 has a circular clearance hole 14 at its center, and a fixing groove 15 is provided on the edge of the clearance hole 14. When the mounting plate 11 is fixedly connected to the mop head 2, the fixing groove 15 and the unlocking part 7 are at the same height. The unlocking part 7 is inserted into the clearance hole 14 and then into the fixing groove 15. The fixing groove 15 is a continuous annular groove. During installation, the outer contours of the mop head 2 and the mounting plate 11 are aligned vertically, and the mop head 2 is pressed downwards. The unlocking part 7 can pass through the clearance hole 14 at any position and enter the fixing groove 15 laterally at any position, without requiring precise alignment of the unlocking part 7 and the fixing groove 15, thus facilitating user installation.

[0042] Preferably, the outer edge of the mop head 2 is provided with or without a flange. When the mounting plate 11 is installed with the mop head 2, the downward direction of the mounting plate 11 is limited only by the unlocking switch 5. The unlocking part 7 is movable and separated from the fixing groove 15. The mounting plate 11 and the wiping material 3 are separated from the mop head 2 without resistance due to gravity.

[0043] To make wiping the object 3 easier to clean and dehydrate, the mop head 2 in this embodiment is equipped with a deceleration mechanism. Specifically, a lower cover 16 is provided below the center of the mop head 2, and an installation cavity is provided between the mop head 2 and the lower cover 16. The deceleration mechanism is provided in the installation cavity. The deceleration mechanism includes a sun gear 17 and a plurality of planet gears 18 surrounding the sun gear 17. The lower cover 16 is used to support the deceleration mechanism, and the size of the lower cover 16 is smaller than the size of the mop head 2. When the mounting plate 11 is installed, the lower cover 16 moves downward into the clearance hole 14, and the unlocking part 7 is movable, fixed, and unlocked in the unlocking gap 19 between the lower cover 16 and the mounting plate 11. The lower cover 16, unlocking part 7, and mounting plate 11 are roughly on the same height plane to reduce the overall height of the mop head 2 and make reasonable use of space. In this space, if the unlocking switch 5 is supported and installed using a base plate or lower cover 16, it would require providing separate installation space for the base plate or enlarging the size of the lower cover 16 to install the deceleration mechanism and unlocking switch 5 inside the lower cover 16, which is cumbersome and could even lead to mutual interference when the deceleration mechanism and unlocking switch 5 are operating. Therefore, installing the unlocking switch 5 by suspension can save space for installing the base plate or lower cover 16. In cases where the deceleration mechanism is no longer needed, such as... Figure 9 and 10 Simply remove the components of the deceleration mechanism, leaving the lower cover 16 to maintain aesthetics, or remove the lower cover 16 directly without affecting the installation and removal of the unlocking switch 5 and the mounting plate 11. No further adjustments to the overall structure of the mop head 2 are required, making the overall structure of the mop head 2 applicable to different styles and models with different structures and functions, thus improving the versatility of the mop head 2.

[0044] Because the unlocking switch 5 is located off-center on the mop head 2, and the mounting plate 11 and the outer edge of the mop head 2 are only in contact or not in contact, if only one unlocking switch 5 is provided, the mounting plate 11 on the side away from the unlocking switch 5 will not be supported by the unlocking switch 5 and will easily tilt downwards, or even fall off after the wiping material 3 absorbs water and becomes heavy. In this embodiment, there are two unlocking switches 5, which are symmetrically distributed on opposite sides of the mop head 2 or the unlocking gap 19, so that the supporting force between each position of the mounting plate 11 and the unlocking switch 5 is more balanced. Of course, the number of unlocking switches 5 can also be set to three, four, or other numbers, so that the mounting plate 11 is fixed to the mop head 2 at multiple points, thereby further improving the support stability of the mounting plate 11.

[0045] In addition to ensuring that the mounting plate 11 is supported from below to prevent it from falling, it also needs to be supported from above to prevent it from wobbling. In this embodiment, for example... Figure 5 The unlocking switch 5 extends outward to form a support portion 20, which overlaps vertically with the mounting plate 11 to provide support for the mounting plate 11 from above. If there are two unlocking switches 5, and the two unlocking switches 5 are located on the same straight line, the mounting plate 11 in the area on both sides of this straight line cannot be supported by the support portion 20. To solve the support problem, such as Figure 11 The mounting plate 11 and the mop head 2 are also respectively provided with a first positioning part 21 and a second positioning part 22. The first positioning part 21 is located on the top of the mounting plate 11, and the second positioning part 22 is independent of the unlocking switch 5. The first positioning part 21 and the second positioning part 22 provide vertical support. When there are three or more unlocking switches 5, the support above the mounting plate 11 is balanced, and the support of the second positioning part 22 can also be removed.

[0046] Since the vertical thickness of the mounting plate 11 is less than the vertical thickness of the lower cover 16, in addition to using the support part 20, the first positioning part 21, and the second positioning part 22 for support, other methods can also be used, such as... Figure 12 The mop head 2 has an annular stepped portion 23 in the middle, making the center height of the mop head 2 higher than the outer periphery. The deceleration mechanism and the lower cover 16 are located in the higher area, while the mounting plate 11 is located in the lower area. The unlocking switch 5 and the switch hole 4 are located at the step portion 23. The area between the step portion 23 and the lower cover 16 forms the unlocking gap 19. The top surface of the mounting plate 11 fits against the bottom surface of the outer periphery of the mop head 2 for support. Alternatively, a second positioning portion 22 can be provided on the mop head 2 in this area to cooperate in supporting the mounting plate 11.

[0047] Based on the shape of the ring-shaped stepped portion 23, the unlocking switch 5 and the switch hole 4 are positioned on the stepped portion 23, which integrates the shape of the hand control portion 6 and the surface of the mop head 2 into a single unit. Pressing the hand control portion 6 from the side of the stepped portion 23 moves the unlocking switch 5 as a whole. Specifically, as shown... Figure 1 and 3 The switch hole 4 is provided with a first recessed platform 24. The depth of the first recessed platform 24 is adapted to the thickness of the hand control part 6. After the unlocking switch 5 is installed, the hand control part 6 is supported above the first recessed platform 24, and the top surface of the hand control part 6 is flush with the top surface of the mop head 2. The first recessed platform 24 is located in the switch hole 4 near the center of the mop head 2. The middle of the first recessed platform 24 is provided with a downward extending baffle 25. The baffle 25 is provided with a first positioning post 26. The unlocking switch 5 is spaced apart from the baffle 25. The unlocking switch 5 is provided with a second positioning post 27. The first positioning post 26 and the second positioning post 27 respectively support the two ends of the elastic member 28. The elastic force of the elastic member 28 keeps the unlocking part 7 away from the baffle 25. In this embodiment, the elastic member 28 is set as a compression spring, and the first positioning post 26 and the second positioning post 27 are inserted into the compression spring.

[0048] Preferably, the baffle 25 has a first clearance area 29 on both sides, and the unlocking switch 5 has a second clearance area 30 in the middle. The first clearance area 29 and the second clearance area 30 are arranged in the form of slots or holes, and the second positioning post 27 and the elastic member 28 are both located in the second clearance area 30. When the unlocking switch 5 is moved to unlock, the baffle 25 and the first positioning post 26 enter the second clearance area 30, and the elastic member 28 is compressed and deformed in the clearance area. The unlocking switch 5 protruding from both sides of the second clearance area 30 enters the first clearance area 29. The arrangement of the first clearance area 29 and the second clearance area 30 allows the unlocking switch 5 and the baffle 25 to be interlocked, thereby saving the movement space required for the function of the unlocking switch 5 and making the structure of the mop head 2's installation and removal of the wiping material 3 and the deceleration mechanism more compact.

[0049] In this embodiment, the step portion 23 divides the surface of the mop head 2 into a first surface 31 and a second surface 32 of different heights, with the first surface 31 being higher than the second surface 32. The switch hole 4 extends from the first surface 31 to the second surface 32. The switch hole 4 is connected between the first surface 31 and the second surface 32 by a support wall 33. The side of the first recessed platform 24 is integrally formed with the support wall 33. The size of the switch hole 4 on the first surface 31 is larger than the size on the second surface 32, so that the unlocking switch 5 can form upper and lower support on the second surface 32. Specifically, the lower ends of the second surface 32 and the support wall 33 extend into the switch hole 4 to form a limiting part 8. The first limiting point 9 supported by the hand control part 6 is above the limiting part 8, and the second limiting point 10 of the unlocking part 7 is below the limiting part 8, so as to jointly clamp the limiting part 8. During the movement of the unlocking switch 5, the first limiting point 9, the second limiting point 10 and the limiting part 8 form a mutually cooperating moving track, or the first limiting point 9, the limiting point, the limiting part 8 and the first sinking platform 24 form a mutually cooperating moving track.

[0050] To facilitate the installation and fixation between the hand control unit 6 and the unlocking unit 7, the first limiting point 9 extends laterally inward to form an installation groove 34 between the first limiting point 9 and the top of the controlled part. The top of the connecting section 13 extends laterally outward to form an installation groove 34 between the connecting section 13 and the unlocking unit 7. The hand control unit 6 is placed above the switch hole 4 and away from the baffle 25. The unlocking section is placed below the switch hole 4 so that the connecting section 13 passes upward through the switch hole 4. The hand control unit 6 and the unlocking unit 7 are pushed to move closer together until the hand control unit 6 and the unlocking unit 7 are tightly fitted with the corresponding installation grooves 34. On the basis of tight fit, buckles, glue, barbs or screws can be set between the hand control unit 6 and the unlocking unit 7 for further fixation.

[0051] In this embodiment, the wiping material 33 is provided with multiple circumferentially arranged bristle holes 35 on the mounting plate 11. Each bristle hole 35 is fixed with a soft, absorbent wiping material unit such as a cloth strip or cotton thread. The inner end of the wiping material 3 in the length direction is fixed in the bristle hole 35 and extends out of the bristle hole 35 to form a bristle section 36. The part of the wiping material 3 located outside the bristle hole 35 can be stretched outward along the radial direction of the mounting plate 11 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 37 for cleaning the floor. When the rotating mop is in a stationary and suspended position, the outer part of the wiping section 37 naturally falls down below the mop head 2 under gravity, reducing the area of ​​the horizontal cross section so that it can enter the mop bucket for washing and dehydration.

[0052] Preferably, the length of the wiping segment 37 is greater than the length of the hair-planting segment 36.

[0053] Preferably, the edge of the hair implantation hole 35 is provided with a serrated protrusion, which can be inserted into the wiping material 3 to prevent the wiping material 3 from falling out of the hair implantation hole 35.

[0054] Since the existing cotton thread fixing process makes it difficult to remove the hair graft segment 36, in order to prevent the hair graft segment 36 from entering the clearance hole 14 and obstructing the connection between the unlocking switch 5 and the mounting plate 11, in this embodiment, a lower stop block 38 is provided below the fixing groove 15. The lower stop block 38 extends downward or toward the center area of ​​the mounting plate 11, and the lower stop block 38 is used to block the hair graft segment 36 from entering the fixing groove 15.

[0055] The lower stop 38 can block the hair-planting section 36 in two ways. First, the width of the lower stop 38 is not less than the length of the hair-planting section 36. The width of the lower stop 38 is the distance it extends towards the center of the mounting plate 11. By widening the lower stop 38, the end of the hair-planting section 36 is prevented from obstructing the movement of the unlocking switch 5. Second, a groove 39 is provided between the hair-planting hole 35 and the lower stop 38. When the hair-planting section 36 is pressed, its end inserts into the groove 39, or a portion of the hair-planting section 36 is pressed into the groove 39, shortening the overlap length between the end of the hair-planting section 36 and the lower stop 38. The groove 39 can be structured by extending the outer edge of the lower stop 38 downward to form a step, creating a height difference between the step and the hair-planting hole 35, with the space formed by this height difference being the groove 39. Alternatively, the groove 39 can be structured by extending the wall of the hair-planting hole 35 downward to form a frustum 40 based on the step created in the lower stop 38, with the recessed space between the frustum 40 and the step forming the groove 39. The combination of the frustum 40 and the groove 39 extends the length that the hair-planting section 36 needs to travel to enter the fixing groove 15, thereby preventing the hair-planting section 36 from obstructing the unlocking switch 5. Of course, in both of the above methods, the width of the lower stop 38 and the groove 39 can be extended simultaneously to further prevent the end of the hair-planting section 36 from obstructing the unlocking switch 54.

[0056] like Figure 2 and 15The structure of the first positioning part 21 and the second positioning part 22 is described in detail. The first positioning part 21 is configured as multiple teeth 41 arranged in a circle, and the second positioning part 22 is configured as multiple inserts 42. The teeth 41 and the inserts 42 cooperate to position the parts. When the mounting plate 11 and the mop head 2 are aligned vertically, the teeth 41 and the inserts 42 are staggered and engaged for positioning. The mounting plate 11 is supported and positioned vertically in both directions through the cooperation of the teeth 41 and the inserts 42 and the unlocking part 7. At the same time, the teeth 41 extend upward and the inserts 42 extend downward. The engagement of the teeth 41 and the inserts 42 prevents the mounted plate 11 from rotating relative to the mop head 2 after installation. This limits the mounting plate 11 vertically and circumferentially on the mop head 2, allowing the cleaning material 3 to rotate synchronously with the mop head 2 for cleaning and dehydration. In other embodiments, the first positioning part 21 may be configured as a plurality of inserts 42, and the second positioning part 22 may be configured as a plurality of teeth 41 arranged in a circle. When the mounting plate 11 and the mop head 2 are in the mounting position, the inserts 42 may engage with any of the teeth 41, thereby preventing the mounting plate 11 from rotating relative to the mop head 2.

[0057] Preferably, the sides of any tooth 41 and any insert 42 are set as inclined surfaces. During the installation of the wiping material 3, when the tooth 41 and the insert 42 are not at a fully engaged angle, by applying force in the up and down direction, the tooth 41 and the insert 42 can adjust their angle and position along the inclined surface to achieve a fully engaged state. To avoid the tooth 41 and the insert 42 being in a state where their ends are abutting and unable to engage, the ends of the tooth 41 and the insert 42 can be set as pointed tips or arc segments, thereby expanding the angle range of the automatic adjustment of the engagement state of the tooth 41 and the insert 42. This eliminates the need for visual alignment and manual adjustment of the position of the mop head 2 and the mounting plate 11, making the installation process of the wiping material 3 more convenient.

[0058] In addition to pressing the unlock switch 5 first to misalign the unlocking part 7 with the fixing groove 15, and inserting the wiping material 3 into the fixing groove 15 when the unlocking part 7 and the fixing groove 15 are at the same height, the installation of the wiping material 3 can also be done without pressing the unlock switch 5. This is achieved by applying downward force to the mop head 2 or mop handle 1, pushing the unlock switch 5 to automatically move to the position misaligned with the fixing groove 15 and into it. Specifically, the lower end of the unlocking part 7 is provided with a guide surface 43. When the mounting plate 11 is placed in the preset position of the mop head 2, the guide surface 43 contacts the mounting plate 11, and the mop head 2 is subjected to a downward force. The unlock switch 5 abuts against the mounting plate 11 at the position of the guide surface 43. Under the action of the guide surface 43, the mounting plate 11 pushes the unlock switch 5 to move until the unlocking part 7 is located within the clearance hole 14. Under the action of the elastic member 28, the unlocking part 7 is inserted into the fixing groove 15 and positioned. Of course, in order to make the movement of the unlocking switch 5 smoother, a guide surface 43 can also be provided at the top edge of the mounting plate 11. Preferably, both the unlocking part 7 and the guide surface 43 on the mounting plate 11 are inclined surfaces.

[0059] 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.
