The present application claims the benefit of Chinese Patent Application No. 202221999495.X filed on Jul. 29, 2022, the contents of which are incorporated herein by reference in their entirety.
The present application relates to the technical field of brushes, and in particular to a powered tool brush and a powered tool having same.
When dirt removal is performed in a manually brushing manner, dirt is often not completely brushed away due to insufficient friction between a brush head and a part to be subjected to dirt removal. Therefore, there is a powered tool brush in the market, for example, an electric drill brush head, which is generally made of plastic, and the plastic brush head is implanted in an electric drill bit, which has poor integrity. When in use, the plastic brush head is easily damaged and pressed to be crooked, and also causes a scratch on the surface of an article. Moreover, the plastic brush head located outermost is easily stuck in a slit of the part to be subjected to dirt removal, which results in bristle loss.
The application aims to solve one of the technical problems in the related art at least to a certain extent. For this, the application provides a powered tool brush. A brush head is directly formed on a structural support member by integral injection moulding, and the brush head effectively wraps the structural support member, such that the two are prevented from sliding relative to each other or being disengaged from each other, thereby improving the integrity of the powered tool brush.
The application also provides a powered tool, which uses the powered tool brush.
The technical solution used in the application is: providing a powered tool brush, which includes:
After the above-mentioned structure is used, the bottom wall and the side wall of the brush head enclose to form a cavity for accommodating the structural support member, which cavity can effectively wrap the structural support member. The brush body is directly formed on the bottom wall by integral injection moulding, and the brush body includes a plurality of bristle structures formed by the bottom wall extending in the direction away from the support member. The bonding force between the bristle structures and the bottom wall is strong, such that the bristle structures are not easily damaged and pressed to be crooked and are not prone to disengagement, and the integrity of the powered tool brush is improved.
According to one embodiment of the application, the brush head is also provided with an edge covering part, and the edge covering part is an annular structure formed by the side wall extending towards the axis position of the brush head.
According to one embodiment of the application, a surface of the structural support member inwardly recesses to form an anti-skid groove, the brush head is provided with an anti-skid contour, which is fitted to the anti-skid groove. The provision of the anti-skid groove and the anti-skid contour can enhance the bonding force between the structural support member and the brush head, so as to prevent the two from rotating relative to each other by taking the central axis of the structural support member as a rotation axis, thereby effectively transferring a torque from a power unit to the position of the brush head.
According to one embodiment of the application, the brush head is formed by the structural support member by means of injection moulding or glue injection machining and in the form of an insert.
According to one embodiment of the application, the brush head is provided with an injection moulding support hole, and the injection moulding support hole is fitted to a support rod for supporting the structural support member in a mould.
According to one embodiment of the application, the connecting member is made of metal, and the structural support member is formed by the connecting member by means of injection moulding or glue injection machining and in the form of an insert.
According to one embodiment of the application, the bottom wall is provided with a bristle implantation part for the implantation of bristle into the structural support member, and the bristle implantation part is located within a region, which is covered by the brush head. The bristle implantation part is located within the region, which is covered by the brush head, and the outermost bristle brush head of the bristle implantation part does not easily come into contact with the slit of a part to be subjected to dirt removal, which contact results in bristle loss.
According to one embodiment of the application, the bottom wall extends in a direction away from the structural support member to form a circle of an anti-splashing part, and the brush head and/or the bristle implantation part is located within the circle of the anti-splashing part.
According to one embodiment of the application, the connecting member is a square handle, a cylindrical handle, a five-pit handle or a hexagonal handle.
According to one embodiment of the application, the brush head is made of TPR and/or TPE and/or TPU and/or silica gel.
A powered tool includes the powered tool brush according to any one of the above embodiments, and a powered tool body. the powered tool body is provided with the rotation drive end, which rotates around an axis, and the powered tool brush is connected to the rotation drive end by means of the connecting member. The powered tool includes a pneumatic powered tool, an electric powered tool and hydraulic powered tool, and a combination thereof.
