The application provides a cleaning brush, including brush 10 and tweezers 20, brush 10 includes the brush head 11 and the connecting portion 12 of mutual fixed, tweezers 20 can be along brush 10 length direction and connecting portion 12 detachably grafting fixed.

For convenience of description, a state in which the forceps 20 is inserted into and fixed to the connection portion 12 of the brush 10 is defined as a clamped state, and a state in which the forceps and the connection portion 12 are separated from each other is defined as a separated state.

Referring to fig. 1, the brush 10 and the tweezers 20 are combined together to form a cleaning brush, so that the cleaning brush has a detached state and a clamped state for use: in the detached state, the forceps 20 can be used alone to realize the gripping function; in the clamped state, since the tweezers 20 and the brush 10 are inserted and fixed along the length direction of the brush 10, the tweezers 20 can be used as a brush handle of the cleaning brush to be held by a user, so that the brushing function of the cleaning brush is normally used.

In addition, the cleaning brush of this application is in the joint state with tweezers 20 as the brush holder, therefore cleaning brush's volume and occupation space are close with ordinary cleaning brush under the joint state, can normally hold in the floor-scrubbing machine base.

It should be noted that, the tweezers 20 can be detachably inserted and fixed with the connecting portion 12 along the length direction of the brush 10, and the tweezers 20 and the brush 10 can be mutually inserted and detachably fixed through insertion, and the detachably fixed mode can be a common fixing mode such as clamping, interference fit or bolt fixing, and the application is not limited herein.

Referring to fig. 1 to 3, in some embodiments, the connecting portion 12 is provided with a clamping cavity 12a, and the clamping end of the forceps 20 can be inserted into the clamping cavity 12a and clamped and fixed with the connecting portion 12.

After the two clamping parts of the tweezers 20 are extruded and inserted into the clamping cavity 12a, the two clamping parts can abut against the inner wall of the clamping cavity 12a under the self-elastic action of the tweezers 20, so that clamping and fixing are realized.

As shown in fig. 1 to 3, in some embodiments, the clamping end has a clamping protrusion 21a, and a clamping hole 12b corresponding to the clamping protrusion 21a is formed on the inner wall of the clamping cavity 12 a; by the engagement between the engaging projection 21a and the engaging hole 12b, the fixing reliability between the forceps 20 and the connecting portion 12 in the engaged state can be increased.

In some embodiments, each clamping portion is provided with at least one clamping protrusion 21a, respectively.

Referring to fig. 1 to 3, in some embodiments, a clamping hole 12b penetrates the connecting portion 12; in the clamped state, the clamping protrusion 21a protrudes outwards from the outer surface of the connecting part 12; so as to increase the contact area between the clamping protrusion 21a and the clamping hole 12b and further increase the fixation reliability between the forceps 20 and the connecting portion 12 in the clamped state.

In some embodiments, the clamping protrusion 21a includes a cylindrical clamping portion and a hemispherical protruding portion, where the clamping portion is closely attached to the inner wall of the clamping hole 12a, so as to further increase the contact area and increase the clamping firmness; the hemispherical protruding portion can play a certain guiding role, so that the clamping protruding portion 21a can be conveniently clamped into the clamping hole 12, and the assembling and disassembling difficulty between the tweezers 20 and the brush 10 is reduced.

Referring to fig. 1 to 3, in some embodiments, the forceps 20 is divided into a small diameter section 21 and a large diameter section 22 along the length direction, a step surface is formed between the small diameter section 21 and the large diameter section 22, and the clamping end is located at the small diameter section 21; in the clamped state, the step surface is abutted against the end surface of the connecting part 12, which is far away from the brush head 11.

The step surface can play a role in positioning, when the step surface is propped against the connecting part 12, the clamping protrusions 21a and the clamping holes 12b are positioned at the same height, and at the moment, clamping can be completed only by rotating the tweezers 20 or the brush 10 until the clamping protrusions 21a correspond to the clamping holes 12b, so that the loading and unloading difficulty between the tweezers 20 and the brush 10 is further reduced.

In some embodiments, the outer peripheral surface of the large diameter section 22 is flush with the connecting portion 12 to optimize the grip of the cleaning brush in the clamped state.

Referring to fig. 3, in some embodiments, the ratio of the length of the small diameter section 21 to the length of the forceps 20 is one third or more; the small diameter section 21 is used for being clamped with the connecting part 12, and if the length of the small diameter section 21 is too short, radial shaking easily occurs between the tweezers 20 and the brush 10, so that the clamping firmness of the tweezers 20 and the brush 10 in the clamped state can be ensured by the length ratio of the small diameter section 21 to the tweezers 20 being more than or equal to one third.

In some embodiments, the small diameter section 21 has a length of 5cm or more for the conventional size of the cleaning brush used in the scrubber to ensure firm engagement.

Referring to fig. 1, 3 and 4, in some embodiments, the cleaning brush further includes a stop block 30, and in the clamped state, the stop block 30 is located between two clamping portions of the tweezers 20 and abuts against the tweezers 20 along the clamping direction of the tweezers 20.

It will be appreciated that in the clamped state, when the user holds the cleaning brush, a pressing force is applied to the tweezers 20, and if the holding strength is not controlled, the tweezers 20 may be separated from the connecting portion 12; the stop block 30 arranged against the tweezers 20 can prevent the tweezers 20 from deforming along the clamping direction due to overlarge holding force, thereby avoiding the situation that the tweezers 20 are separated from the brush 10.

In addition, since the pressing force of the user in the holding state presses the stopper 30 through the forceps 20, there is a large static friction between the forceps 20 and the stopper 30, and the stopper 30 is not easily separated from the forceps 20.

Referring to fig. 1, 3 and 4, in some embodiments, in the clamped state, the side surface of the stop block 30 is flush with the outer peripheral surface of the forceps 20 or is trapped inside the forceps 20; in order to avoid the influence of the holding feeling of the tweezers 20 caused by the protrusion of the stop block 30 from the tweezers 20 in the clamped state.

In some embodiments, the edges of the two gripping portions of the forceps 20 are chamfered to avoid scratching by the user during the holding process, and also to provide a guiding function to facilitate the installation of the stop block 30.

Referring to fig. 1, 3 and 4, in some embodiments, the stop block 30 has a quick release protrusion 31; in the clamped state, the quick release protrusions 31 protrude from the outer peripheral surfaces of the tweezers 20; the stop block 30 can be detached from the tweezers 20 by pressing the quick release protrusions 31, so that the detachment difficulty of the stop block 30 is reduced.

In some embodiments, the quick release protrusions 31 are semi-spherical to optimize the pressing feel.

Referring to fig. 1, 3 and 4, in some embodiments, in the clamped state, the outer peripheral surface of the forceps 20 is flush with the outer peripheral surface of the connecting portion 12, so as to be convenient for a user to hold.

In some embodiments, the connecting portion 12 and the large diameter section 22 are each cylindrical to facilitate grasping by a user.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
