Abstract

The patent discloses an electric toothbrush head and an electric toothbrush, comprising a brush handle connecting part which is in power connection with a brush handle of the electric toothbrush, an extending part which extends upwards from the top end of the brush handle, a soft rubber part which is coated outside the extending part, wherein an opening is formed in the rear surface of the soft rubber part, at least one part of the extending part is exposed outside the rear surface of the opening from the opening, the brush bristle part comprises a plurality of implants Mao Huan fixedly arranged on the soft rubber, at least one part of the implant rings are positioned outside the front-rear direction projection of the extending part, and the other part of the implant rings are positioned inside the front-rear direction projection of the extending part. The binding force between the soft rubber and the brush head is improved through the extension part exposed out of the soft rubber, so that the soft rubber can be relatively stably kept on the brush head. When the movable bristle rings are connected with each other, the exposed extension parts can keep the soft rubber from being excessively deformed in use so as to stabilize the soft rubber and the bristle rings from loosening or separating from the brush head.

Description

Electric toothbrush head and electric toothbrush Technical Field This patent belongs to electric toothbrush technical field, and particularly relates to an electric toothbrush head and electric toothbrush. Background Electric toothbrushes have been widely used in the prior art because they use a motor as a driving source to clean teeth more conveniently and efficiently, and thus are favored by users. However, the electric toothbrush adopts a motor as a power source, so that the tooth brushing force and frequency of the electric toothbrush cannot be the same as those of manual tooth brushing, and the condition that the electric toothbrush head hits teeth often causes inconvenience to a user, so that the prior art shows a flexible toothbrush head which uses a soft rubber material as a bristle implantation part inclusion in the toothbrush head. Such a brush head is indeed friendly to the consumer in use, but presents difficulties for the durability of the brush head, etc., mainly because if bristles are implanted in the soft gel, the bonding strength of the bristles and the brush head may be insufficient, as the soft gel itself does not have a strong deformation retaining ability, and the bristles may not meet the requirements of a proper extraction force. Disclosure of Invention The present application has been made in view of the above-mentioned needs of the prior art, and an object of the present application is to provide a toothbrush head for an electric toothbrush, which provides a high binding force between bristles and the toothbrush head in a soft toothbrush head. In order to solve the above problems, the technical solution provided by the present application includes: The electric toothbrush head is characterized by comprising a brush handle connecting part, an extending part, a soft rubber part and brush hair parts, wherein the brush handle connecting part is in power connection with a brush handle of an electric toothbrush, the extending part extends upwards from the top end of the brush handle, the soft rubber part is coated outside the extending part, an opening is formed in the rear surface of the soft rubber part, at least one part of the extending part is exposed out of the rear surface of the opening from the opening, the brush hair part comprises a plurality of implants Mao Huan fixedly arranged on the soft rubber, at least one part of the implant hair rings is positioned outside the front-rear direction projection of the extending part, and the other part of the implant hair rings is positioned inside the front-rear direction projection of the extending part. Preferably, the hair-planting ring comprises Zhou Weizhi Mao Huan and a central hair-planting ring, the peripheral hair-planting ring is provided with a plurality of hair-planting Mao Huan units, at least part of the hair-planting Mao Huan units are connected together through connecting strips and located outside the front-back direction projection of the extension part, the central hair-planting ring is provided with a plurality of hair-planting holes, and the central hair-planting Mao Huan is located at least partially inside the front-back direction projection of the extension part.
