Description

Technical Field

[0001] The utility model relates to a cleaning brush with a replaceable brush head. Background Art

[0002] A cleaning brush with a replaceable brush head in the prior art usually includes a brush head and a brush handle detachably connected to the brush head. The two are combined when the brush handle clamps the brush head. However, this structure usually requires a clamped portion on the brush head for clamping by the brush handle. The clamped portion is made of non-degradable material, and the complete degradation of the disposable brush head cannot be achieved. If the entire brush head is made of degradable material, the clamped portion needs to be processed separately, and the manufacturing process is complicated. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a cleaning brush with a replaceable brush head which has a reasonable structural design and is convenient to use.

[0004] The utility model adopts the following technical scheme to solve the above-mentioned problems: a cleaning brush with a replaceable brush head comprises a brush head and a brush handle detachably connected to the brush head, the brush handle comprises a hand rod, the hand rod is connected to a connecting mechanism for being detachably connected to the brush head, the connecting mechanism comprises a movable part which can enlarge and reduce the radial size of the brush handle, the brush head has a cavity and an opening for the movable part to extend into the cavity; the movable part is in the cavity and moves toward a side away from the hand rod so that the radial size of the brush handle increases, the movable part tightly abuts against the inner wall of the cavity so that the brush head remains connected to the handle; the movable part is in the cavity and moves toward a side close to the hand rod so that the radial size of the brush handle decreases, so that the brush head can be separated from the handle.

[0005] Wherein, the brush head is made of degradable material.

[0006] There is a length difference between the upper side of the opening and the lower side of the opening in the horizontal direction.

[0007] It also includes a seat for storing brush heads, which includes a cylinder with a gap on the side wall facing the user; the opening of the brush head corresponds to the gap, and the brush handle can extend into the cavity after passing through the gap, and more than two brush heads can be stacked and placed in the cylinder.

[0008] Among them, the movable part includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the side of the hand rod, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the driving rod. The driving rod is slidably connected to the hand rod. When the driving rod slides, it drives the first connecting rod and the second connecting rod to move closer to or away from the hand rod.

[0009] The movable part includes a first connecting rod, which is connected to the hand rod in a radial sliding manner, and a driving rod is connected to the hand rod in an axial sliding manner. The driving rod and the hand rod are connected by inclined surface abutment, and the movement of the driving rod can drive the first connecting rod to approach or move away from the hand rod.

[0010] The brush head is made of degradable materials only, and the outer periphery of the brush head is closed except for the opening.

[0011] Compared with the prior art, the utility model has the following advantages and effects: the connection mechanism of the brush handle in the present application is an expandable and retractable mechanism, and the brush head has an opening that can be inserted into the interior of the brush head. The combination of the two is more concise and reliable, and after the brush handle is arranged in the brush head, it has better support for the brush head, and the focus point during brushing is more suitable.
