Technical Field

The invention relates to the technical field of small personal care appliances, in particular to a toothbrush head and an electric toothbrush.

Background

Among the correlation technique, the toothbrush head includes support and brush hair, and the brush hair sets firmly on the support, and the high-frequency vibration through the motor drives the brush hair high-frequency vibration on the toothbrush head in order to clean the tooth, and it is poor to should set up clean tooth effect.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art or the related art.

To this end, a first aspect of the invention is directed to a toothbrush head.

A second aspect of the invention provides a powered toothbrush.

In view of this, a first aspect of the invention provides a toothbrush head comprising: the toothbrush head comprises a toothbrush head main body, a handle and a handle, wherein the toothbrush head main body comprises a support and first bristles; the hair planting base is movably connected with the support and comprises second bristles; the driving piece is arranged on the brush head main body and used for driving the hair planting base to move relative to the support.

The invention provides a toothbrush head which comprises a toothbrush head main body, a bristle planting base and a driving piece. Wherein, the bristle planting seat is movably connected with the support of the brush head main body, and the driving part can drive the bristle planting seat to move relative to the support.

The brush head main body comprises first bristles, and the bristle planting base comprises second bristles. The first bristles are fixedly arranged on the support, and when the driving part drives the bristle planting base to move relative to the support, the second bristles also move relative to the first bristles.

Specifically, the electric toothbrush includes a toothbrush head. When the electric toothbrush works, the first bristles vibrate due to the working of a motor of the electric toothbrush. The second brush hair is in the vibration, can also be for first brush hair motion, also, the second brush hair both moves and vibrate for the second brush hair is changeed and is laminated the tooth, can effectively promote the clean effect of tooth. In addition, when the electric toothbrush is operated, the second brush hair can move relative to the first brush hair, so that the tooth cleaning area is increased, and the tooth cleaning efficiency can be accelerated.

That is to say, through the cooperation structure of reasonable setting brush head main part, planting hair seat and driving piece, richened the clean tooth mode of the brush hair of toothbrush head, also promptly, first brush hair and second brush hair combine together, will vibrate clean tooth and the integrative combination of tooth of motion clean tooth, when guaranteeing clean tooth effect, can promote clean tooth efficiency, be favorable to reducing the operation energy consumption of product, promoted the performance and the market competition of product.

The toothbrush head according to the invention can also have the following additional technical features:

in the above technical solution, further, the hair-planting base includes: the second brush bristles are arranged on the first seat body; the driving piece is used for driving the first base body to reciprocate along the first direction.

In this technical scheme, further limit the structure of planting hair seat, specifically, the hair seat includes first pedestal, and the second brush hair is located first pedestal, and first pedestal is as the installation carrier of second brush hair. The first seat body can reciprocate along the first direction under the action of the driving piece, and therefore the second bristles can reciprocate along the first direction under the action of the driving piece.

It will be appreciated that the first bristles vibrate to clean the teeth and the second bristles vibrate to clean the teeth while the toothbrush head is in operation, and are also capable of reciprocating in a first direction. The in-process of second brush hair reciprocating motion when the area of contact of the brush hair of increase toothbrush head and tooth, can also guarantee the clean frequency of brush hair to the tooth for the brush hair is changeed the laminating tooth, is favorable to promoting clean tooth effect.

In any of the above technical solutions, further, an avoidance vacancy is provided at a first side of the support, an avoidance opening is provided at a second side of the support, and the first bristles are provided at the second side of the support; at least one part of the first seat body is positioned in the avoidance vacancy, and the first seat body can move relative to the avoidance vacancy; the second bristles extend out of the outer surface of the support through the avoidance opening.

In this technical scheme, the first side of support is equipped with dodges the vacancy, and the second side of support is equipped with dodges the mouth, and the first side of support and the second side of support set up relatively, and dodge the mouth and dodge the vacancy intercommunication.

At least one part of the first base body is positioned in the avoidance vacancy, and the first base body can move relative to the avoidance vacancy. That is, the avoidance vacancy has the function of accommodating the first seat body, and the avoidance vacancy does not obstruct the movement of the first seat body. This set up the structure of rational utilization the support, when satisfying the user demand of planting hair seat and support swing joint, can not increase the size of the thickness direction of brush head main part.

It can be understood that the second bristles extend out of the outer surface of the support through the avoidance port, that is, when the brush head body and the bristle implanting seat are assembled, the second bristles sequentially pass through the avoidance vacant site and the avoidance port and connect the support and the first seat body together.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention, taken in conjunction with the accompanying drawings and detailed description, is set forth below. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Referring now to figures 1-34, a toothbrush head 100 and a powered toothbrush 200 according to some embodiments of the present invention will be described.

Example 1:

as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9, fig. 10, fig. 11, fig. 12, fig. 13, fig. 14, fig. 15, fig. 16, fig. 17, fig. 18 and fig. 19, the embodiment of the first aspect of the present invention proposes a toothbrush head 100, the toothbrush head 100 comprising a head body 110, a bristle holder 130 and a driving member 140.

The head body 110 includes a support 112 and first bristles 114, the first bristles 114 being disposed on the support 112.

The hair-planting base 130 is movably connected with the support 112, and the hair-planting base 130 comprises second bristles 132.

The driving member 140 is disposed on the head body 110, and the driving member 140 is used for driving the bristle holder 130 to move relative to the support 112.

In detail, the toothbrush head 100 includes a head body 110, a bristle base 130, and a driving member 140. Wherein, the bristle-planting base 130 is movably connected with the support 112 of the brush head main body 110, and the driving member 140 can drive the bristle-planting base 130 to move relative to the support 112.

The head body 110 includes first bristles 114 and the bristle holder 130 includes second bristles 132. The first brush hairs 114 are fixedly arranged on the support 112, and when the driving member 140 drives the hair-planting base 130 to move relative to the support 112, the second brush hairs 132 also move relative to the first brush hairs 114.
