Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of floor brushes, and particularly relates to a floor brush structure capable of adjusting the hinging tightness of a connecting pipe according to a moving condition. BACKGROUND

[0002] As a powerful tool widely used in the cleaning field, a floor brush plays a key role in different scenarios due to its diversified design and rich functions. Whether it is daily floor cleaning at home or large-scale cleaning operations in commercial places and industrial areas, a floor brush can efficiently complete the task with its own advantages.

[0003] However, when a user uses the floor brush to clean every corner, the position and direction of the floor brush need to be frequently changed. For example, when cleaning the bottom of a sofa, a corner or other narrow spaces, the floor brush needs to be constantly twisted and turned to cover every sanitary dead corner. At this time, the dust collection hose connected to the floor brush will also be twisted. However, since the existing floor brush hose lacks a tension adjustment function, the hose cannot be reasonably supported and adjusted during the twisting process. With an increase in the number of uses, the hose will gradually appear excessive bending at the twisted part. Such excessive bending not only narrows the channel inside the hose, affects the smoothness of dust collection, and causes the suction force to decrease, but also accelerates the aging and wear of the hose material. In the long run, the hose may have problems such as rupture and air leakage, which seriously affects the cleaning effect and even makes the floor brush unable to be normally used. SUMMARY

[0004] The purpose of the present application is to solve the problem that the existing floor brush hose lacks a tension adjustment function, the hose cannot be reasonably supported and adjusted during the twisting process, and with an increase in the number of uses, the hose will gradually appear excessive bending at the twisted part. Such excessive bending not only narrows the channel inside the hose, affects the smoothness of dust collection, and causes the suction force to decrease, but also accelerates the aging and wear of the hose material. In the long run, the hose may have problems such as rupture and air leakage, which seriously affects the cleaning effect and even makes the floor brush unable to be normally used.

[0005] To achieve the above purpose, the present application adopts the following technical scheme: a floor brush structure capable of adjusting the hinging tightness of a connecting pipe according to a moving condition, comprising:

[0006] A floor brush lower shell is provided with a dust collection hole, a dust collection pipe is connected to the dust collection hole, and a hose is connected between the dust collection pipe and the handle pipe. The handle pipe is hingedly connected to the floor brush lower shell on both sides, a tensioning member is installed on the inner wall of the floor brush lower shell, and the tensioning member is used to control the tightness of the rotation angle of the handle pipe.

[0007] And the ground brush upper shell is detachably connected on the ground brush lower shell.

[0008] As a further description of the above technical solution:

[0009] The ground brush lower shell is provided with a mounting plate, the mounting plate is provided with a first arc-shaped hole, the ground brush upper shell is provided with a connecting plate, the connecting plate is provided with a second arc-shaped hole, when the ground brush upper shell and the ground brush lower shell are assembled together, the first arc-shaped hole and the second arc-shaped hole form a limiting hole, the handle pipe is provided with a connecting lug on both sides, and the connecting lug is connected on the limiting hole through a hinged shaft.

[0010] As a further description of the above technical solution:

[0011] The tensioning piece comprises a connecting box, a spring and a rotating lug, the rotating lug is rotatably connected on the connecting box, and the spring is connected on the connecting box and the rotating lug at two ends respectively.

[0012] As a further description of the above technical solution:

[0013] The connecting box is provided with a limiting groove, and the spring end is located in the limiting groove.

[0014] As a further description of the above technical solution:

[0015] The connecting lug is connected on the hinged shaft, the rotating lug is provided with a first connecting groove, the hinged shaft is provided with a first connecting block, and the first connecting block is connected in the first connecting groove.

[0016] As a further description of the above technical solution:

[0017] The ground brush upper shell is provided with a mounting groove, the ground brush lower shell is provided with an abutting groove, a clamping block and a connecting column are arranged at the bottom of the limiting shell, the clamping block is clamped in the mounting groove, and the connecting column is connected in the abutting groove.

[0018] As a further description of the above technical solution, the beneficial effects of the present application are:

[0019] 1. In the present invention, a tensioning piece is arranged in the lower shell of the floor brush, and both sides of the handle tube are connected to the lower shell of the floor brush through a hinge shaft, and a first connecting block is arranged on the hinge shaft. The tensioning piece includes a connecting box, a spring and a rotating ear, wherein the rotating ear is provided with a first connecting groove, and the first connecting block and the first connecting groove abut against each other. When the handle tube is parallel to the lower shell of the floor brush, the spring on the inner wall of the rotating ear maintains its original state. When the handle tube is slowly rotated to be perpendicular to the lower shell of the floor brush, the spring is in a compressed state, and the compression resistance of the spring is slowly increasing. This structure can adjust the tension of the handle tube during the rotation process according to the movement of the floor brush. When it is slowly vertical, the hose connected to the handle tube is bent too much, the tensioning force it is subjected to is greater, thereby avoiding damage caused by excessive bending of the hose and improving the cleaning effect.
