Description

Surrounding type sound wave vibration toothbrush
Technical Field
The invention relates to a tooth cleaning mechanism, in particular to an angle-driven telescopic surrounding type sound wave vibration 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.

The technical problem to be solved by the embodiment of the invention is to provide a surrounding type sound wave vibration toothbrush. The tooth cleaning device can improve the usability of the tooth cleaning device and the efficiency of oral cavity cleaning, and provides a solution for improving the tooth brushing compliance of preschool children and the oral cavity cleaning of people with lost teeth and malpositioned teeth.
In order to solve the above technical problems, an embodiment of the present invention provides a surround type sound wave vibration toothbrush, including a brush handle, a U-shaped tooth cleaning socket, a jaw side bristle sheet, a buccal side bristle sheet, an occlusal side bristle sheet, and an eccentric motor disposed in the brush handle;
the U-shaped tooth cleaning groove comprises a fixed wall and a movable wall, the bottom of the movable wall is connected with the bottom of the fixed wall in a sliding mode, and a return spring is arranged between the movable wall and the fixed wall; the jaw side brushing piece and the cheek side brushing piece are respectively fixed on the inner sides of the fixed wall and the movable wall;
the bottom of the fixed wall is matched and connected with the brush handle through a movable shaft, a cam fixedly connected with the movable shaft is arranged on the upper surface of the fixed wall, and the occlusion surface brush sheet is fixedly arranged on the cam surface;
the cam is movably contacted with the inner side surface of the bottom of the movable wall.
And an arc convex body in contact with the movable surface of the cam is arranged on the inner side surface of the bottom of the movable wall.
Wherein the cam is oval.
The return spring is arranged between the end faces of the fixed wall and the movable wall, which are close to each other.
The outer sides of the upper parts of the fixed wall and the movable wall are provided with clamping grooves, and the outer sides of the jaw side brushing piece and the cheek side brushing piece are provided with inverted clamping hooks fixedly connected with the clamping grooves.
Wherein, the fixed wall and the inner wall of the movable wall are provided with a slot for inserting the brushing sheets on the jaw side or the brushing sheets on the cheek side.
Wherein, the brush hair on the jaw side brush hair piece and the cheek side brush hair piece form an included angle of 45 degrees with the direction of the inserted dental arch.
Wherein the movable shaft is eccentrically arranged on the cam.
The surface of the cam is provided with an insertion hole, and the back of the occlusion surface bristle sheet is provided with an insertion column which is fixedly inserted into the insertion hole.
The embodiment of the invention has the following beneficial effects: the design of the surrounding type tooth cleaning brush head mechanism can well clean the jaw side, the cheek side and the occlusal surface of teeth, and can reduce the vomiting symptom caused by pharyngeal reflex. The U-shaped tooth cleaning grooves completely surround the jaw side surface, the cheek side surface and the occlusal surface of the teeth, and the distance between the tooth cleaning grooves, namely the distance between the fixed wall and the movable wall, can be freely stretched and contracted to fit various dentition conditions of different individuals. In addition, the change of the distance between the fixed wall and the movable wall of the embodiment of the invention is changed by linking the movable shaft and the cam to rotate along with the rotation of the brush holder. I.e. the angle of rotation of the brush holder, directly affects the distance between the fixed wall and the movable wall. It is anticipated that embodiments of the present invention will greatly improve the oral problems and reduce the incidence of caries and periodontal disease for both manually handicapped and school-age children with poor compliance. The embodiment of the invention belongs to a surrounding type mouth cleaning instrument, can efficiently and quickly finish the oral cleaning operation, is suitable for various dentition conditions of different individuals, and has universality, simplicity and high efficiency.
