Description

Technical Field

[0001] This utility model belongs to the field of mop technology, and specifically relates to a mop. Background Technology

[0002] Flat mops are a common cleaning tool. Compared to traditional mops, flat mops on the market today have better cleaning effects and higher cleaning efficiency. The clip-on mop is a type of flat mop that allows users to change the mop head without touching it, making it clean, hygienic, and convenient for users.

[0003] Most cloth-clamping mops on the market include a mounting base with two sets of clamping arms that can be movably mounted on it. Users can fix or remove the mop head by controlling the movement of the clamping arms. For example, Chinese Utility Model Patent CN 202323641645.7 discloses a cloth-clamping mop that facilitates mop head replacement. It includes a mop head, a mop handle, a cloth clamping assembly, and a drive assembly. The mop handle includes an outer rod hinged to the mop head and an inner rod slidably mounted inside the outer rod. The cloth clamping assembly includes a main clamping member fixed to the mop head and movable clamping members slidably mounted on one or both sides of the main clamping member. The drive assembly includes a sliding seat slidably mounted vertically on the mop head and a pull rod with one end hinged to the mop head. The sliding seat is drivenly connected to the inner rod, and the other end of the pull rod is hinged to the movable clamping member. A pressure post is provided on the sliding seat, which abuts against the side wall of the pull rod. When clamping the cloth, pressing down on the inner rod causes the sliding seat to slide down, the pressure post pushes the pull rod to swing, and the pull rod drives the movable clamping member to move closer to the main clamping member.

[0004] In the above structure, when disassembling the mop, the user needs to grasp the inner rod and the outer rod with both hands respectively, and then forcefully control the inner rod and the outer rod to slide relative to each other. At this time, the long mop handle can easily affect the user's control of the inner rod and the outer rod, making it inconvenient for the user to disassemble the mop. In addition, since the outer rod is close to the mop head, it is easy for the outer rod to get dirty during use. Although the user does not need to directly touch the mop when changing the mop, they will still come into contact with the dirt, which affects the user's ability to change the mop.
