Multi-angle facial brush with 3D brush head and motion driving method of multi-angle facial brush

Abstract

The invention discloses a multi-angle facial brush with a 3D brush head and a motion driving method of the multi-angle facial brush. The multi-angle facial brush comprises a shell, the brush head and a brush head driving structure. The brush head comprises a bristle base, a connecting part used for receiving driving and an elastic part installed on the connecting part. The brush head driving structure comprises a motor, an eccentric wheel, a linkage part and a connecting shaft used for being connected with the brush head, and an eccentric column of the eccentric wheel stretches upwards into a sliding groove of the linkage part. Under the action of rotation of the motor, the eccentric column acts on the sliding groove of the linkage part, and the brush head conducts plane-direction reciprocating motion and 3D face-attaching elastic deformation motion along with the linkage part and can scrub and clean the surface of the face in a reciprocating mode and be attached to the curved surface of the face to conduct 3D face-attaching deformation, so that user-friendly multi-direction cleaning of the face is achieved, and the multi-angle facial brush better accords with ergonomic design and is more thorough in cleaning; besides, the multi-angle facial brush is simple and reliable in driving structure and method and suitable for being applied and popularized in various products like automatic facial brushes.

Description

technical field [0001] The invention relates to the technology in the field of cleansing brushes, in particular to a multi-angle cleansing brush with a 3D brush head and a motion driving method thereof. Background technique [0002] Earlier, when people cleaned their faces, they used manual cleansing brushes, which had defects such as low efficiency; later, people developed electric facial cleansing brushes, which, through the action of electromagnets and magnets, hang and drive elastic steel sheets to swing from side to side, thus Drive the machine head to swing to achieve the effect of the brush head swinging. In this way, the purpose of the brush head automatically reciprocating along the plane on the skin is realized. Compared with the manual cleansing brush, it is indeed a great improvement and more convenient to use , but it can only clean the surface layer of the skin, it is difficult to deep clean the skin, therefore, it has the defect that the cleaning is not thorou...

Problems solved by technology

[0002] Earlier, when people cleaned their faces, they used manual cleansing brushes, which had defects such as low efficiency; later, people developed electric facial cleansing brushes, which, through the action of electromagnets and magnets, hang and drive elastic steel sheets to swing from side to side, thus Drive the machine head to swing to achieve the effect of the brush head swinging. In this way, the purpose of the brush head automatically reciprocating along the plane on the skin is realized. Compared with the manual cleansing brush, it is indeed a great improvement and more convenient to use However, it can only clean the surface layer of the skin, and it is difficult to clean the skin deeply. Therefore, it has the defect that the cleaning is not thorough enough. At the same time, its structure is more complicated, and its production and assembly are more troublesome.

[0003] And, in the prior art, whether it is a manual facial cleansing brush or an electric facial cleansing brush, the brush head is a fixed and non-deformable structure, and the human face is a 3D curved surface. Therefore, after the cleaning is completed, there will always be some spots that cannot be cleaned. Dead corner, which has the defect of insufficient cleaning
