Description

TECHNICAL FIELD

[0002] The mop with a clamping function is a cleaning tool capable of cleaning through a mop cloth clamped on a mop head.

[0003] Part of the mop with a clamping function, such as the patent with the application number CN202410736788.6, provides a mop with a clamping function, which comprises a mop head shell, a hinge seat arranged on the mop head shell in a lifting manner, a button connected to the hinge seat in a sliding manner and capable of hooking and limiting the mop head shell, a clamping piece arranged on both sides of the mop head shell in a telescopic manner, a connecting rod connected to the hinge seat and the clamping piece in a rotating manner, and a spring capable of elastically acting on the two clamping pieces to slide out of the mop head shell.

[0004] Through the hooking or unhooking between the button and the mop head shell, it is controlled whether the spring can drive the hinge seat to lift, that is, whether the spring can elastically act on the two clamping pieces to slide away from or close to the side edge of the mop head shell. The lower end surface of the clamping piece is necessarily provided with a sharp end protruding from the bottom surface of the mop head shell to ensure that the clamping piece can drag the clamped mop cloth, and the sharp end can fully contact the mop cloth and drive the mop cloth to partially wrinkle, so that the mop cloth is clamped between the clamping piece and the mop head shell.

[0005] However, when the clamping piece is operated in a telescopic manner relative to the mop head shell, the sharp end rubs against the ground, and the sharp end is extremely easy to wear, so that the clamping piece may not be able to or may be difficult to drive the mop cloth to partially wrinkle for clamping in the later use of the mop with a clamping function, the clamping effect of the mop with a clamping function is weakened or even disappears, and the service life of the mop with a clamping function is affected.

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes a cloth-clamping mop that can effectively improve service life, as detailed below: like Figures 1-8 As shown, the cloth-clamping mop that can clamp the mop includes a housing 1, a lower plate 3 that slides and lifts to connect the housing 1, a pusher 2 that slides on the housing 1 and can hook the lower plate 3, a limiting member 8 that connects to the housing 1 and restricts the lower plate 3 from sliding away from the housing 1, and at least two sets of clamping assemblies. Each set of clamping assemblies includes two clamping members 4 that are rotatably mounted on the lower plate 3, and an actuating member 5 that can rotate the clamping members 4. The actuating member 5 is a tension spring or a rubber band. A lifting spring 6 is installed between the housing 1 and the lower plate 3, and a return spring 7 is installed between the pusher 2 and the housing 1.

[0024] In this embodiment, the cloth-clamping mop has two states: Clamping state: The button 2 hooks onto the lower plate 3. The gap between the lower plate 3 and the housing 1 is short. The housing 1 and the lower plate 3 compress the lifting spring 6. The two clamping parts 4 in the clamping assembly of the housing 1 are in a horizontal and relatively staggered state. The two clamping parts 4 stretch the action part 5, increasing the elastic potential energy of the action part 5.

[0025] Release state: The hook between the button 2 and the lower plate 3 is released. The lifting spring 6 elastically acts on the lower plate 3 and the housing 1, increasing the distance between the lower plate 3 and the housing 1. This causes the part of the housing 1 that acts on the clamping member 4 to move away from the clamping member 4. The setting of the actuating member 5 ensures that the clamping member 4 is always in contact with the housing 1. This causes the clamping member 4 to be set obliquely downward on the lower plate 3. The two clamping members 4 in a set of clamping components are arranged on the two sides of an inverted isosceles trapezoidal structure on the lower plate 3.

[0026] When the mop is switched from the clamping state to the releasing state, the pressing piece 2 is pressed, so that the pressing piece 2 is unhooked from the lower plate 3. The lifting spring 6 can act on the space between the lower plate 3 and the shell 1, and the acting piece 5 acts on the clamping piece 4 to turn down relative to the lower plate 3 until the maximum space between the lower plate 3 and the shell 1 is limited by the limiting piece 8.

[0027] When the mop is switched from the releasing state to the clamping state, the lower end of the clamping piece 4 is contacted with the ground and the mop is pressed down. The lower plate 3 can act on the pressing piece 2 to slide and compress the reset spring 7 until the lower plate 3 is hooked with the pressing piece 2. At the same time, the shell 1 acts on the clamping piece 4 to turn up relative to the lower plate 3 until the clamping state is reached. The clamping process can be completed by pressing down without other manual operations, which is simple and convenient.

[0028] Preferably, when the clamping piece 4 turns down, the clamping angle between the clamping piece 4 and the lower plate 3 is less than or equal to 90°, that is, the turning-up angle of the clamping piece 4 is less than or equal to 90°, and the lower end of the clamping piece 4 can be chamfered. When the clamping angle between the clamping piece 4 and the lower plate 3 is 90°, the chamfer can act on the clamping piece 4 to turn up when the mop is pressed down.

[0029] In the present application, the clamping piece 4 is installed by rotation, so that when the clamping piece 4 contacts the mop and the ground, the clamping piece 4 turns up under the downward force, so that the part of the clamping piece 4 contacting the ground changes in rotation. The space between the lower ends of the two clamping pieces 4 in a set of clamping assemblies changes, the clamping piece 4 drives and clamps the mop, reduces the friction of the same part of the clamping piece 4 contacting the ground, ensures the stability of the clamping piece 4 acting on the mop, makes the clamping effect of the clamping piece 4 last for a long time, and effectively improves the service life of the mop.

The stop block 22 can limit the pressing piece 2 from being slid away from the side opening of the installation cavity 11.

[0031] The installation cavity 11 is further provided with a blocking wall 24, and the reset spring 7 elastically acts between the blocking wall 24 and the pressing piece 2. In order to avoid the movement of the reset spring 7 when elastically acting, the pressing piece 2 is provided with a guide column 23 capable of being inserted with the reset spring 7, and the reset spring 7 elastically acts on the partial exposure of the pressing piece 2 to the side opening of the installation cavity 11.

When the mop is pressed, the lower plate 3 moves upwards, the guide inclined surface 9 on the hook portion 31 can act on the pressing piece 2 to slide into the installation cavity 11, or the hook portion 31 can act on the guide inclined surface 9 on the pressing piece 2 to push the pressing piece 2 to slide into the installation cavity 11, or the guide inclined surface 9 on the hook portion 31 can be in close contact with the guide inclined surface 9 on the pressing piece 2 to push the pressing piece 2 to slide into the installation cavity 11. Preferably, the blocking block 22 is located between the hook groove 25 and the side surface of the pressing piece 2 exposed to the side opening of the installation cavity 11.
