Description

A kind of brush for electric toothbrush

Technical field

The utility model relates to electric toothbrush technology field, in particular to a kind of brush for electric toothbrush.

Background technique

Traditional manual toothbrush is a kind of tool in common cleaning oral cavity, but manual toothbrush usually will appear to tooth Sordid situation is cleaned, manual operation dynamics and the lack of standardization of movement will cause bleeding gums, and enamel is caused to be ground The problems such as damage.Occur a kind of electric toothbrush on the market now, by the vibration for the vibrating elements being arranged in handle, and will vibration Dynamic be transferred on the bristle of brush head is brushed teeth, but existing electric toothbrush often exists cannot clean oral cavity, meeting well The defects of enamel is damaged.And these above-mentioned defects are unreasonable often caused by the design of existing brush for electric toothbrush Caused by.

Summary of the invention

A kind of brush for electric toothbrush good, that damage will not be caused to tooth that the purpose of the utility model is to provide cleaning effects Head.

To achieve the goals above, the utility model provides a kind of brush for electric toothbrush, and brush head includes brush handle and bristle, The head of brush handle is arranged in bristle, and bristle installing zone is arranged in the head of brush handle, and multiple bristle installations are provided in bristle installing zone Hole, bristle are mounted in bristle mounting hole, and bristle mounting hole includes the first mounting hole and the second mounting hole, and the first mounting hole is cut Face is oval, and the section of the second mounting hole is in an one wide narrow water droplet arc；Bristle installing zone is oval, bristle peace It fills and is respectively set on the outside of the middle part in area there are two the first mounting hole, other regions setting multiple second of bristle installing zone is installed Hole.

As seen from the above technical solution, it is seen then that when being transmitted in the first mounting hole of ellipse due to vibrational energy, energy Decaying it is big so that the vibration frequency of the bristle in the first mounting hole is small；Since vibrational energy is in the second installation of water droplet arc When transmitting in hole, the decaying of energy is small, so that the vibration frequency of the bristle in the second mounting hole is big；When brushing teeth, the first mounting hole Interior bristle is located at gingival position, and small vibration frequency is conducive to protect gum, prevents from causing to damage to gum, and the second installation Bristle in hole is located at dental surface, and big vibration frequency is conducive to clean dental surface.It is cleaned by above-mentioned subregion Mode, that is, can guarantee the cleaning effect of electric toothbrush, and can avoid gingival lesions.

Further embodiment is that the tail portion of brush handle is provided with hollow connecting cavity, and connecting cavity from-inner-to-outer includes cylinder The first connecting cavity and truncated cone-shaped the second connecting cavity, be evenly arranged with multiple convex blocks on the peripheral wall of the first connecting cavity.

As it can be seen that the convex block of the peripheral wall of the first connecting cavity receives vibrational energy, so that vibrational energy is transferred to brush head, improve The transmission efficiency of energy.
