Description

Surrounding type sound wave vibration toothbrush

Technical Field

The utility model relates to a clean mechanism of tooth especially relates to an angle drives flexible encircleing type sound wave vibrations toothbrush.

Background

Brushing is the simplest way of oral care, but a considerable proportion of people lack scientific guidance. Currently, the most effective method of brushing teeth is recognized by the dental medical community as the modified pasteur brushing method, i.e., the horizontal vibrating brush method. The method requires that the bristles of the toothbrush form an angle of 45 degrees with the long axis of the toothbrush when the toothbrush is held by hand, and point to the junction of the gum and the tooth to carry out horizontal vibrating brushing. However, over 90% of individuals use the wrong method of brushing their teeth (e.g., lateral brushing), which can lead to gum damage (e.g., bleeding, atrophy) and inefficient cleaning, which can affect the user's perception and judgment of the brushing effect and, in turn, underestimate the healthy effectiveness of brushing their teeth. Secondly, the conventional toothbrush design, whether manual or electric, requires the user to adjust the angle and direction of the brush head by himself to clean the jaw side, buccal side and occlusal surface of the teeth, which has certain technical requirements, especially when cleaning the jaw side of the upper and lower jaws, it may stimulate the pharyngeal reflex to cause vomiting reaction. In addition, pigment accumulation of anterior teeth can be caused by smoking, drinking tea and the like, and the lack of timely and effective cleaning can inevitably cause double losses of aesthetic property reduction and functional damage of teeth. Therefore, there is a need for a surround type sound wave toothbrush which is easy to operate, convenient and practical, and cleans around the jaw side, buccal side and occlusal surface of surrounding teeth to solve the oral problems of people.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Refer to the schematic structural diagrams shown in fig. 1 and 2.

The utility model provides a surround type sound wave vibrations toothbrush of embodiment, including brush holder 1, U type tooth cleaning groove 2, jaw side brush hair piece 3, buccal side brush hair piece 4, interlock face brush hair piece 5, set up eccentric motor 6 in the brush holder.

As shown in fig. 3 and 4, the U-shaped tooth cleaning slot 2 includes a fixed wall 21 and a movable wall 22, the fixed wall 21 and the movable wall 22 are both symmetrical "L" shaped, the bottom of the movable wall 22 is U-shaped and is provided with a slot 221, two sides of the bottom 211 of the fixed wall 21 are slidably disposed in the slot 221, and a return spring (the spring is omitted in the figures) is disposed at an end portion between the two.
