Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, specifically to a mop head that facilitates the attachment and removal of mop cloths. Background Technology

[0002] In the field of cleaning tools, the mop is a core tool for daily floor cleaning, and the reliability of the connection between the mop head and the mop cloth, as well as the ease of replacement, directly affects the user experience. In existing technology, users need to unlock the corresponding clamping teeth first, and then, when inserting the mop cloth into the clamping mechanism, they also need to open the clamping teeth to insert the mop cloth. This makes it impossible to keep the clamping mechanism open at all times for easy installation of the mop cloth. Utility Model Content

[0003] To solve the above problems, this utility model provides a mop head that facilitates the attachment and removal of the mop cloth:

[0004] A mop head for easy attachment and removal of mop cloths includes a dust mop holder, a mop joint connecting to the mop handle, and toothed components respectively disposed on both sides of the mop joint. The toothed components include a toothed clamp seat fixedly connected to the upper surface of the dust mop holder and two symmetrically arranged clamping teeth. The upper part of the toothed clamp seat has a mounting groove, and the middle of the mounting groove has a hinge seat that hinges the two clamping teeth. The hinge seat divides the mounting groove into two toothed grooves for placing the mop cloth. The toothed grooves and the clamping teeth form an engagement mechanism for clamping and fixing the mop cloth. The inner wall of the toothed groove has a groove that interlocks with the outer surface of the clamping teeth. The first elastic tooth set is formed by the elastic locking mechanism. The upper surfaces of the two teeth near the hinge seat are provided with outwardly protruding extension plates. The extension plates extend obliquely upward toward the direction of the first elastic tooth set. The upper part of the extension plates is provided with a pressing inner surface corresponding to the teeth and a magnetic outer surface opposite to the teeth. When the user presses the inner surface, the teeth overcome the elastic locking force of the first elastic tooth set and open relative to the tooth groove. At this time, the magnetic outer surfaces of the adjacent extension plates are magnetically attracted to each other and tightly attached, so that the tooth groove remains open.

[0005] Preferably, the clamping tooth includes a hinge end and a tooth body. The hinge end includes a pivot for connecting to the hinge seat and two side end blocks that are fixedly connected to the ends of the pivot. The side end blocks and the hinge seat form a limiting fit.

[0006] Preferably, the magnetic outer surface is provided with multiple longitudinally distributed micro transverse teeth. When two magnetic outer surfaces are magnetically attracted and attached to each other, the two magnetic outer surfaces engage and lock into place. This engagement and locking of the magnetic outer surfaces ensures that they remain in a locked position when magnetically attracted and attached, thereby limiting the rotation angle of the two teeth relative to the tooth holder, making it easier for the user to place the mop into the tooth groove.

[0007] Preferably, the clamping teeth further include an elastic torsion spring sleeved on the pivot, the end of the elastic torsion spring abutting against the bottom surface of the tooth groove, the elastic torsion spring being used to generate an elastic force on the clamping teeth to cause them to open outward relative to the tooth groove.

[0008] Preferably, the clamping teeth further include a gravity block adapted to the side end block. The weight of the gravity block is greater than the combined weight of the tooth body, the pivot, and the side end block. The outer end face of the side end block facing away from the pivot has a virtual circular surface. A semi-circular insert groove is provided in the virtual circular surface. The semi-circular insert groove is used to lock and fix the gravity block. When the two clamping teeth are turned outward at the same angle relative to the tooth groove until the magnetic outer surface is magnetically attracted to each other, the gravity block is located at the bottom of the virtual circular surface. The gravity block is used to keep the clamping teeth open relative to the tooth groove. The principle of the gravity block in this application is actually the same as that of a roly-poly toy. Through the gravity effect of the high-density gravity block on the low-density tooth body, the clamping teeth obtain a force that tends to be upright. This produces the technical effect that once the magnetic outer surface is magnetically attracted to each other, the two clamping teeth are turned outward and open relative to the tooth groove, making it convenient for users to place the edge of the mop cloth directly into the tooth groove. Compared to the technical solution using elastic torsion springs, this application can avoid the phenomenon of elastic torsion springs snagging on mop cloths.

[0009] Preferably, the tooth body, pivot, and side end block are made of lightweight plastic, while the gravity block is made of hard metal.

[0010] Preferably, the upper surface of the tooth body is provided with an outwardly extending arc-shaped pressure plate, and the tooth clamp seat is provided with an outwardly protruding flange on the side of the first elastic tooth group opposite to the outer edge of the tooth groove. The mop cloth covers the outer surface of the flange and enters the tooth groove. When the clamping teeth are engaged and fixed with the tooth groove, the arc-shaped pressure plate and the flange constitute a second clamping mechanism for clamping the mop cloth.

[0011] Preferably, the tooth body is provided with a second elastic tooth group corresponding to the first elastic tooth group. The second elastic tooth group consists of a plurality of second elastic protrusions evenly arranged along the outer edge of the tooth body. The first elastic tooth group consists of a plurality of first elastic protrusions evenly arranged horizontally on the inner end face of the tooth groove. The first elastic protrusions and the second elastic protrusions are matched one-to-one.

[0012] Beneficial effects: Under normal conditions, the clamping teeth and the toothed groove are locked in place, thus engaging the mop cloth within the groove. At this time, the first elastic locking tooth group is positioned at the upper end of the clamping teeth, limiting the outward movement of the clamp and maintaining a stable locked state between the clamping teeth and the toothed groove. When replacement is needed, the user applies pressure to the inner surface, causing the clamping teeth to overcome the elastic locking force of the first elastic locking tooth group and open relative to the toothed groove. At this time, the magnetic outer surfaces of adjacent outer folding plates magnetically attract and adhere to each other, keeping the toothed groove open. By pressing the inner surface of the clamping teeth, the user can operate with one hand to open the clamping teeth outward, while the magnetic outer surfaces automatically magnetically adhere, achieving a continuously open toothed groove, making the loading and unloading of the mop cloth very convenient.

[0022] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described with reference to Examples 1-2.

[0023] Example 1: Appendix Figure 1-7 As shown, a mop head for easy attachment and removal of mop cloth includes a dust mop holder 1, a mop joint 2 connecting to the mop handle, and toothed components respectively disposed on both sides of the mop joint 2. The toothed components include a toothed clamp seat 3 fixedly connected to the upper surface of the dust mop holder 1 and two symmetrically arranged clamping teeth 4. The upper part of the toothed clamp seat 3 is provided with a mounting groove, and the middle of the mounting groove is provided with a hinge seat 5 that hinges the two clamping teeth 4. The hinge seat 5 divides the mounting groove into two toothed grooves 6 for placing the mop cloth. The toothed grooves 6 and the clamping teeth 4 form an engagement mechanism for clamping and fixing the mop cloth. The inner wall of the toothed groove 6 is provided with a toothed groove that engages with the outer end of the clamping teeth 4. The first elastic tooth group 7, which constitutes the elastic locking adaptation, has two clamping teeth 4 with outwardly protruding extended folding plates 8 on the upper end face near the hinge seat 5. The extended folding plates 8 extend obliquely upward toward the first elastic tooth group 7. The upper part of the extended folding plates 8 has a pressing inner surface 9 corresponding to the clamping teeth 4 and a magnetic outer contact surface 10 facing away from the clamping teeth 4. When the user presses the inner surface 9, the clamping teeth 4 overcome the elastic locking force of the first elastic tooth group 7 and open outward relative to the tooth groove 6. At this time, the magnetic outer contact surfaces 10 of the adjacent extended folding plates 8 are magnetically attracted to each other and tightly attached, so that the tooth groove 6 remains open.

[0024] like Figure 1-2 As shown, the clamping tooth 4 includes a hinge end 11 and a tooth body 12. The hinge end 11 includes a pivot 13 that connects to the hinge seat 5 and two side end blocks 14 that are fixedly connected to the ends of the pivot 13. The side end blocks 14 and the hinge seat 5 form a limiting fit. The clamping tooth 4 also includes a gravity block 16 that adapts to the side end blocks 14. The weight of the gravity block 16 is greater than the total weight of the tooth body 12, the pivot 13 and the side end blocks 14. The outer end face of the side end block 14 facing away from the pivot 13 is provided with a virtual circular surface 17. A semi-circular insert groove 18 is provided in the virtual circular surface 17. The semi-circular insert groove 18 is used to lock and fix the gravity block 16. When the two clamping teeth 4 are turned outward at the same angle relative to the tooth bite groove 6 until the magnetic outer surface 10 is magnetically attracted and tightly attached to each other, the gravity block 16 is located at the bottom of the virtual circular surface 17. The gravity block 16 is used to keep the clamping teeth 4 in an open state relative to the tooth bite groove 6. The principle of the gravity block 16 in this application is actually the same as that of a roly-poly toy. The high-density gravity block 16 exerts its gravity on the low-density tooth body 12, causing the clamping teeth 4 to receive a force that tends to make them upright. This results in the two clamping teeth 4 maintaining a relatively upright position relative to the tooth groove 6 once the magnetic outer surfaces 10 are magnetically attracted and pressed together. Figure 1-2The outward-folding design allows users to directly place the edge of the mop cloth into the engagement groove. Compared to solutions using elastic torsion springs, this application avoids the phenomenon of the elastic torsion spring hooking onto the mop cloth. The tooth body 12, pivot 13, and side end block 14 are made of lightweight plastic, while the gravity block 16 is made of hard metal. The upper surface of the tooth body 12 is provided with an outwardly extending arc-shaped pressure plate 19. The tooth clamp 3 has an outwardly protruding flange 20 on the side opposite to the first elastic tooth group 7 on the outer edge of the tooth groove 6. The mop cloth covers the outer surface of the flange 20 and enters the tooth groove 6. When the clamping teeth 4 are engaged and fixed with the tooth groove 6, the arc-shaped pressure plate 19 and the flange 20 constitute a second clamping mechanism for engaging the mop cloth. The tooth body 12 is provided with a second elastic tooth group 21 corresponding to the first elastic tooth group 7. The second elastic tooth group 21 consists of a plurality of second elastic protrusions evenly arranged along the outer edge of the tooth body 12. The first elastic tooth group 7 consists of a plurality of first elastic protrusions evenly arranged horizontally on the inner end face of the tooth groove 6. The first elastic protrusions and the second elastic protrusions are matched one-to-one.

[0025] Example 2: As Figure 8 As shown, a mop head for easy attachment and removal of mop cloths includes a dust mop holder 1, a mop joint 2 connecting to the mop handle, and toothed components respectively disposed on both sides of the mop joint 2. The toothed components include a toothed clamp seat 3 fixedly connected to the upper surface of the dust mop holder 1 and two symmetrically arranged clamping teeth 4. Each clamping tooth 4 includes a hinge end 11 and a tooth body 12. The hinge end 11 includes a pivot 13 for hinged hinge seat 5. A mounting groove is provided on the upper part of the clamp seat, and a hinge seat 5 for hinged connection of the two clamping teeth 4 is provided in the middle of the mounting groove. The hinge seat 5 will mount... The slot is divided into two toothed grooves 6 for placing the mop cloth. The toothed grooves 6 and the clamping teeth 4 form a clamping mechanism for clamping and fixing the mop cloth. The inner wall of the toothed groove 6 is provided with a first elastic clamping tooth group 7 that is adapted to the outer end of the clamping teeth 4 to form an elastic locking position. The upper end face of the two clamping teeth 4 near the hinge seat 5 is provided with an outwardly protruding extension plate 8. The extension plate 8 extends obliquely upward towards the first elastic clamping tooth group 7. The upper part of the extension plate 8 is provided with a pressing inner surface 9 corresponding to the clamping teeth 4 and a magnetic outer surface 10 facing away from the clamping teeth 4.

[0026] The magnetic outer surface 10 is provided with a plurality of longitudinally distributed micro transverse toothed racks 15. When two magnetic outer surfaces 10 are magnetically attracted to each other, the two magnetic outer surfaces 10 engage and lock into place with each other.

[0027] The upper surface of the tooth body 12 is provided with an outwardly extending arc-shaped pressure plate 19. The tooth clamp 3 is provided with an outwardly protruding flange 20 on the side of the first elastic tooth group 7 opposite to the outer edge of the tooth groove 6. The mop cloth covers the outer surface of the flange 20 and enters the tooth groove 6. When the clamping teeth 4 are engaged and fixed with the tooth groove 6, the arc-shaped pressure plate 19 and the flange 20 constitute a second clamping mechanism for engaging the mop cloth. The tooth body 12 is provided with a second elastic tooth group 21 corresponding to the first elastic tooth group 7. The second elastic tooth group 21 consists of a plurality of second elastic protrusions evenly arranged along the outer edge of the tooth body 12. The first elastic tooth group 7 consists of a plurality of first elastic protrusions evenly arranged horizontally on the inner end face of the tooth groove 6. The first elastic protrusions and the second elastic protrusions are matched one-to-one.

[0028] Principle: Under normal conditions, the clamping teeth 4 and the toothed grooves 6 are locked in place, thus gripping the mop cloth within the grooves. At this time, the first elastic locking tooth group 7 is positioned at the upper end of the clamping teeth 4, thereby limiting the outward movement of the clamping teeth 4 and maintaining a stable locked state between the clamping teeth 4 and the toothed grooves 6. When replacement is needed, the user applies pressure to the inner surface 9, causing the clamping teeth 4 to overcome the elastic locking force of the first elastic locking tooth group 7 and open outward relative to the toothed grooves 6. At this time, the magnetic outer surfaces 10 of the adjacent outer extension folding plates 8 magnetically attract each other, keeping the toothed grooves 6 open. In this embodiment, the user only needs to magnetically attract the two clamping teeth 4 when they are nearly upright relative to the toothed grooves 6. At this time, the two magnetic outer surfaces 10 engage with each other, keeping the two clamping teeth 4 in a nearly upright state. Both toothed grooves 6 are open, making it easy for the user to place the mop into the toothed grooves 6 simultaneously.

[0029] This embodiment 2 achieves the same technical effect as embodiment 1, keeping the two clamping teeth 4 in a neutral and fitted state, thus keeping the two toothed grooves 6 open simultaneously for easy installation and removal of the mop cloth. However, in actual use, it was found that embodiment 2 requires a certain magnetic position, while the clamping teeth 4 in embodiment 1 automatically swing and flip to the set position, with a relatively high degree of automation.

[0030] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
