Description
Technical Field
[0001] This utility model belongs to the field of mop technology, specifically relating to a mop head and mop with replaceable mop cloth. Background Technology
[0002] A mop is a cleaning tool consisting of a mop handle and a mop head, primarily used for scrubbing floors.
[0003] Currently, most flat mops on the market come equipped with replaceable mop heads. For easy replacement, the mop head needs a mechanism for quickly clamping and releasing the mop head. Existing clamping mechanisms often use complex snap-on or knob structures, which suffer from inconvenience in operation, unreliable clamping, and susceptibility to damage due to their complex structure. For example, some mop heads, after locking, are prone to the locking lever loosening due to accidental impacts, causing the mop head to fall off during mopping; others require users to exert considerable force or perform multiple steps to lock or unlock, resulting in a poor user experience. Therefore, it is necessary to provide a mop head with a simple structure, convenient operation, and reliable locking mechanism for replaceable mop heads. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a mop head and mop with a simple structure, reliable locking and convenient operation that can replace the mop head.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A replaceable mop head includes a mop head body, a locking link, and a locking spring. The mop head body has a locking surface for contacting and supporting the mop. The connecting end of the locking link is rotatably connected to a first end of the mop head body. The fixed end of the locking spring is fixed to a second end of the mop head body. A locking groove is formed in the middle of the locking spring. The free end of the locking spring forms a guide surface that smoothly transitions with the locking groove. The free end of the locking link is provided with a locking part. When the locking link rotates from the open position to the locked position, the locking part is configured to slide along the guide surface and eventually engage in the locking groove, so that the rod of the locking link is parallel to the locking surface of the mop head body, together forming a locking space for pressing the mop.
[0006] In some embodiments, the opening of the locking groove faces the outer wall of the second end of the mop head body, such that a clamping space for clamping the locking part is formed between the locking groove and the outer wall of the second end of the mop head body.
[0007] In some embodiments, the locking groove is an arc-shaped groove whose curvature matches the curvature of the sliding trajectory of the locking part, so that the locking part forms a surface contact locking after being engaged.
[0008] In some embodiments, the tail of the locking portion extends to form a handle portion that is easy for the user to operate.
[0009] In some embodiments, the locking surface of the mop head body is provided with clamping teeth for increasing the friction of the mop cloth.
[0010] In some embodiments, the locking spring is made of an elastic material and allows the locking portion to slide into or out of the locking groove through its own elastic deformation.
[0011] In some embodiments, the connecting end of the locking link is provided with a connecting hole, and the first end of the mop head body is provided with a receiving groove for accommodating the connecting end, and a positioning shaft inserted into the connecting hole is provided in the receiving groove.
[0012] In some embodiments, a guide portion is connected between the rod body of the locking link and the locking part, and a guide groove is provided on the mop head body corresponding to the guide portion. The guide portion moves with the locking link and reciprocates within the guide groove.
[0013] A mop includes a mop handle and a mop head, wherein the mop head body is provided with a socket, and one end of the mop handle is detachably inserted into the socket.
[0014] In some embodiments, a protective end cap is fitted onto the end of the mop handle away from the mop head, and the mop handle is covered with an anti-slip sleeve for preventing slippage.
[0015] The beneficial effects of this utility model are as follows: Through the rotation of the locking linkage and the cooperation of the locking spring, the user only needs a simple flipping action to complete the pressing and locking of the mop head, which is convenient and efficient and simplifies the process of changing the mop head. The locking part finally engages in the locking groove, forming a stable mechanical interlocking structure, ensuring that even under front-to-back and side-to-side friction during mopping, the mop head will not come loose from the mop head, and the locking effect is firm and reliable. When the locking linkage is in the locked position, its rod body and the locking surface of the mop head body are parallel and opposite, forming a complete locking space. This results in a large force-bearing area for the mop head being pressed, and the pressure distribution is uniform, avoiding the problem of mop head damage or incomplete pressing caused by local stress concentration. The guide surface on the locking spring provides a smooth path for the sliding of the locking part, guiding it accurately into the locking groove, reducing the difficulty of operation, and improving the smoothness and certainty of use.

The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0020] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-2As shown, a replaceable mop head includes a mop head body 1, a locking link 2, and a locking spring 3. The mop head body 1 has a locking surface 11 for contacting and supporting the mop. The connecting end 21 of the locking link 2 is rotatably connected to the first end of the mop head body 1. The fixed end of the locking spring 3 is fixed to the second end of the mop head body 1. A locking groove 31 is formed in the middle of the locking spring 3. The free end of the locking spring 3 forms a guide surface 32 that smoothly transitions with the locking groove 31. The free end of the locking link 2 is provided with a locking part 22. When the locking link 2 rotates from the open position to the locked position, the locking part 22 is configured to slide along the guide surface 32 and eventually engage in the locking groove 31, so that the rod body 23 of the locking link 2 is parallel to the locking surface 11 of the mop head body 1, together forming a locking space 100 for pressing the mop. Figure 2 As shown, the opening of the locking groove 31 faces the outer wall of the second end of the mop head body 1, forming a clamping space 300 between the locking groove 31 and the outer wall of the second end of the mop head body 1 for clamping the locking part 22. The opening direction of the locking groove and the outer wall of the second end of the mop head body together form the clamping space. This further enhances the enclosure and constraint of the locking part, making the locking state more stable and effectively resisting vibrations and impacts generated during use, preventing accidental unlocking. The locking groove 31 is an arc-shaped groove, and its curvature matches the curvature of the sliding trajectory of the locking part 22, so that the locking part 22 forms a surface contact lock after being engaged. Designing the locking groove as an arc-shaped groove that matches the sliding trajectory of the locking part achieves surface contact between the locking part and the locking groove. This can significantly increase the contact area, reduce pressure, make the lock more stable, less prone to wear, and extend the service life. The fixing end of the locking spring is fixed to the mop head body by screws, and the guide surface is an arc-shaped surface or a slope. The tail of the locking part 22 extends to form a handle 24 for easy user operation. The force application point of the handle makes opening and locking operations more effortless and convenient, especially when hands are wet or gloves are worn, enhancing the product's ergonomic design. The locking surface 11 of the mop head body 1 is provided with clamping teeth 111 to increase friction with the mop head. Adding clamping teeth to the locking surface increases the static friction between the mop head and the mop head. The clamping teeth can more effectively grip the mop head, preventing it from slipping or shifting within the locking space, ensuring the mop head remains fixed during cleaning. The locking spring 3 is made of elastic material and allows the locking part 22 to slide into or out of the locking groove through its own elastic deformation. The locking spring operates using its own elastic deformation properties. The process of the locking part sliding into and out of the locking groove is a flexible and elastic snap-fit action, which ensures sufficient preload when locking and does not require excessive force when unlocking. It has a good operating feel, and is simple in structure, low in cost and highly reliable.
[0022] like Figure 1As shown, the connecting end 21 of the locking link 2 is provided with a connecting hole 211, and the first end of the mop head body 1 is provided with a receiving groove 12 to accommodate the connecting end 21. A positioning shaft 13 is provided in the receiving groove 12 and inserted into the connecting hole 21. The receiving groove and the positioning shaft provide a stable and reliable rotation fulcrum for the locking link. This structure is simple to process and assemble, has a firm connection, and ensures that the locking link can rotate smoothly around a fixed axis with high action accuracy.
[0023] A guide portion 25 connects the rod body 23 of the locking linkage 2 to the locking part 22. A guide groove 14 is provided on the mop head body 1 at the corresponding position of the guide portion 25. The guide portion 25 moves with the locking linkage 2 and reciprocates within the guide groove 14. The guide groove can precisely guide and limit the movement trajectory of the locking linkage, preventing it from deviating or wobbling during rotation, making the locking action more stable and accurate, and further improving the structural stability and operating feel of the product.
[0024] like Figure 3 As shown, a mop includes a mop handle 4 and a mop head. The mop head body 1 has a socket 15, and one end of the mop handle 4 is detachably inserted into the socket 15. A protective cap 5 is fitted onto the end of the mop handle 4 away from the mop head, and an anti-slip sleeve 6 is wrapped around the mop handle 4 to prevent slippage. The protective cap prevents the end of the mop handle from scratching the floor or the user, and also prevents dust and moisture from entering the handle. The anti-slip sleeve improves the user's grip comfort and safety, preventing slippage during operation. Therefore, this mop has the advantages of quick mop replacement, reliable locking, and convenient operation.
[0025] By rotating the locking linkage and engaging the locking spring, users can easily tighten and lock the mop head with a simple flipping motion, making operation convenient, efficient, and simplifying the mop replacement process. The locking part ultimately engages in the locking groove, forming a stable mechanical interlock structure. This ensures that even under front-to-back and side-to-side friction during mopping, the mop head will not detach, providing a secure and reliable lock. When the locking linkage is in the locked position, its rod and the locking surface of the mop head body are parallel and opposite, forming a complete locking space. This results in a large pressure-bearing area for the mop head, with even pressure distribution, preventing mop damage or inadequate tightening caused by localized stress concentration. The guide surface on the locking spring provides a smooth path for the sliding of the locking part, guiding it accurately into the locking groove, reducing operational difficulty and enhancing the smoothness and certainty of use.
[0026] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
