Description

Technical Field

[0001] This utility model relates to the field of property cleaning tools, specifically to a detachable mop head. Background Technology

[0002] In property cleaning tools, a dust mop is a tool used to clean dust from floors. It mainly consists of a mop head, a handle, and a pole, which are connected in sequence. Additionally, the mop head has a mop cloth, which is generally replaceable. Existing methods for connecting the mop cloth and the dust mop holder primarily fall into three categories: The first is a side-insertion type, where the back of the mop cloth has an insertion port, and the dust mop holder is inserted into the mop cloth's pocket through this port. The second is a folding type, where the dust mop holder itself is foldable. It has pockets on both sides of the mop cloth, with the openings of the two pockets facing each other, located in the middle of the back of the mop cloth. Users insert one pocket first, then fold and unfold to insert the other pocket. The third is a strap, button, or adhesive type, where the mop cloth has only one pocket. After placing the dust mop holder inside the pocket, the pocket is secured to the mop cloth using Velcro or straps.

[0003] Existing technologies, such as the dust mop holder disclosed in application number 201730195483X, have a rigid, non-extendable structure. Another example is the dust mop holder disclosed in application number 2020209749435, which includes a dust mop head. The dust mop head is an elliptical metal frame with an integral metal plate in the center. The center of the metal plate has a raised recess that is movably connected to a plastic movable head, allowing it to swing forward and backward. All of these dust mop holders are rigid, fixed structures and cannot achieve a foldable effect, thus failing to accommodate the second type of mop head installation. Furthermore, since the dust mop holder disclosed in application number 2020209749435 cannot achieve detachable connection between the plastic movable head and the dust mop head, it also cannot achieve the first type of mop head installation. Therefore, the existing technologies can only accommodate a limited range of mop types and cannot adapt to multiple mop types. Utility Model Content

[0004] To solve the above problems, this utility model provides a detachable mop head:

[0005] A detachable mop head includes a dust mop frame and a connecting head. The dust mop frame includes a fixed U-shaped frame, a movable U-shaped frame, and a connecting frame disposed between the two. Both the fixed U-shaped frame and the movable U-shaped frame are U-shaped frame structures made of elastic metal or elastic plastic. The fixed U-shaped frame is fixedly connected to the connecting frame, and the movable U-shaped frame is hinged to the connecting frame. The movable U-shaped frame can be flipped and folded relative to the connecting frame. When the fixed U-shaped frame and the movable U-shaped frame are spread apart, the dust mop frame can be used to support and unfold the mop. Two upright plates are fixedly connected to the upper end face of the connecting frame, and each upright plate is provided with a connecting hole.

[0006] The connector includes a handle connector and a mop head connector that are movably connected to each other. The mop head connector has a tube body, and a retractable plug is provided inside the tube body. The plug can protrude or retract relative to the end of the tube body, and the two ends of the plug and the connecting hole form a detachable plug-in adapter.

[0007] Preferably, the connecting frame includes a plate body, a fixed tube, and an opening slot. A mounting plate is fixedly connected or detachably snap-fitted to the inner surface of the plate body. The two ends of the movable U-shaped frame are provided with relatively extending hinge posts, which are movably hinged to hinge holes provided between the mounting plate and the plate body. Two fixed tubes and two opening slots are provided, symmetrically arranged on both sides of the plate body. The fixed tube is fixedly connected to the end of the fixed U-shaped frame. The opening slot is elastically fitted to the movable U-shaped frame. Normally, the movable U-shaped frame elastically expands outward and is positioned within the opening slot. When the movable U-shaped frame elastically retracts inward and passes through the opening of the opening slot, the movable U-shaped frame can be flipped and folded relative to the connecting frame along the hinge holes. This application uses a fixed-coverage connection method for the end of the fixed U-shaped frame via the fixed tube, while the movable U-shaped frame and the connecting frame are movably connected without corresponding weld points. Compared to the welding method in the prior art, this significantly improves the durability and structural stability of the dust mop frame.

[0008] Preferably, the mounting plate and the plate body are fixedly connected, and the mounting plate and the plate body are fixed by snap-fit ​​connection, riveting or adhesive.

[0009] Preferably, both ends of the mounting plate are integrally connected to the outwardly protruding upright plate, which is exposed through an internal perforation provided in the plate body.

[0010] Preferably, the mounting plate and the plate body are detachably connected by a snap-fit ​​mechanism. Each side of the upright plate is provided with an elastic hook. Under normal conditions, the elastic hook and the inner through hole form an elastic snap-fit. When the elastic hooks on both sides of the same upright plate are retracted relative to each other, the upright plate can slide out relative to the inner through hole. At this time, the mounting plate can be separated from the plate body.

[0011] Preferably, the mounting plate has multiple evenly distributed cylindrical grooves, which together with the inner surface of the plate body form the hinge holes. Users can select the appropriate cylindrical groove to fit through the hinge pin of the movable U-shaped frame, thereby controlling the relative position of the movable U-shaped frame and the fixed U-shaped frame, and thus achieving the purpose of controlling the length of the dust mop frame.

[0012] Beneficial effects: Because the dust mop frame of this application is foldable, and the connector adapted to it is also detachable from the dust mop frame, this application can be adapted to various types of mops, making it convenient and quick, and also enabling corresponding disassembly and transportation.
