Description

Technical Field

[0001] The invention belongs to the technical field of mops, and in particular relates to a foldable mop. Background Art

[0002] A mop, also known as a mopping rag, refers to a long-handled cleaning tool for scrubbing the floor. It also generally refers to long-handled cleaning tools. Traditional mops mostly have wiping objects directly installed on the handle. However, during the wiping process of this type of mop, only the mop rod presses the wiping object against the floor, the force-bearing area is small, and the cleaning efficiency is low. Most of the existing mops on the market have a mop plate. During use, the mop plate presses the wiping object against the floor, thereby increasing the force-bearing area of ​​the wiping object and improving the cleaning efficiency.

[0003] In order to improve the cleaning efficiency of the mop, many mop trays are relatively long, but such mops are inconvenient to store and transport, and are not convenient to clean and spin dry. Therefore, some foldable and unfoldable mops have appeared on the market, such as a foldable mop disclosed in Chinese invention patent CN2018104443670, which includes a mop rod and a mop head connected to the bottom end of the mop rod, the mop head includes at least two fixed rods located in the same plane and in a straight line when stretched, the at least two fixed rods can be folded and contracted with each other in the plane where they are located, and the bottom of the mop rod is also connected to a driving member coaxial with the mop rod, and the driving member rotates around its axial direction, thereby driving the folding of the at least two fixed rods. The mop rod can be retracted or expanded, and the number of the fixed rods is an even number; the driving member is connected to the bottom end of the mop rod, and the driving member rotates around the axial direction of the mop rod along with the mop rod; the at least two fixed rods are a left fixed rod and a right fixed rod, and the two ends of the driving member are respectively provided with downward hinges, which are respectively hinged to the inner ends of the left fixed rod and the right fixed rod, and an auxiliary rotating member is sleeved on the outer side of the bottom of the mop rod, and the auxiliary rotating member is located on the outer side of the driving member, and downward sliders are respectively provided on the two ends of the auxiliary rotating member, and the upper surfaces of the left fixed rod and the right fixed rod are respectively provided with guide grooves extending along the length direction thereof, and the sliders are located on the outer side of the hinge shaft and in the guide grooves and move along the guide grooves.

[0004] In this structure, the driving member is driven to rotate by the rotation of the mop rod. However, in order to facilitate the use of the user, the diameter of the mop rod is generally small, and it is very difficult for the user to control the rotation of the mop rod. In addition, since the length of the fixed rod is much larger than the radius of the mop rod, it can be known from the principle of lever that the fixed rod is easily folded toward the middle when subjected to force, which is inconvenient for the user.
