Description

Acoustic wave type electric toothbrush for orthodontics

Technical Field

The utility model relates to an acoustic wave formula electric toothbrush, concretely relates to acoustic wave formula electric toothbrush for just abnormal.

Background

There are more and more powered toothbrushes on the market today, but it is extremely rare for a particular group of people to be addressed. Due to the orthodontic devices in the oral cavity of orthodontic people, orthodontic devices such as brackets and arch wires are worn in the mouth of an orthodontic patient, a special oral environment with a plurality of obstacles and a plurality of dead angles is formed, friction force required by cleaning surfaces (gum, tooth surface and orthodontic oral devices) is different, and the space in the oral cavity is small.

For a common (manual) toothbrush, according to survey, most people use the common toothbrush to brush teeth, the time is not in place, the region is not correctly divided, the teeth are brushed in a correct and effective posture, the tooth brushing strength is not fixed, and the cleanness of the dead angle of the common toothbrush is very low. Such brushing often results in bleeding gums, ineffective cleaning of the oral cavity, and certain damage to the orthodontic devices within the oral cavity of the orthodontic patient.

The right tooth brushing method mainly adopts the pasteurization tooth brushing method at present, and the specific method is that a toothbrush and a long axis of teeth form an angle of 45 degrees and point to the apical direction (upper teeth upwards and lower teeth downwards), a gingival and tooth junction area is pressed, a part of bristles enter a gingival sulcus, a part of bristles are paved on a gingival margin and extend into an adjacent gap as far as possible, and the bristles are horizontally vibrated for 10 times in a short distance in the front-back direction in situ by soft pressure.

The electric toothbrush on the market at present has the following problems aiming at orthodontic people:

(1) arranging bristles: the existing arrangement of the brush hair is mainly divided into U-shaped, V-shaped, plane-shaped, wave-shaped, hemispherical and other ways for arrangement. The arrangement mode of the bristles does not relate to the oral cavity shape of orthodontic people, dead angles exist in cleaning the tooth surfaces of the orthodontic people, and the phenomenon that the orthodontic devices in the mouth are collided easily occurs;

(2) the bristle materials are as follows: the material of the bristles not only influences water absorption, antibiosis and the like, but also determines the softness and hardness degree of the bristles, and the smaller the softness and hardness value of the bristles, the softer the bristles, the less stimulation to gum is; however, in contrast, the bristles are soft, so that the cleanliness of the tooth surface is reduced, and the bristles are easily damaged, thereby affecting the service life. The existing brush hair materials comprise natural bristle, nanometer soft rubber brush hair, nylon filament brush hair, silica gel toothbrush brush hair, PBT fiber, bamboo charcoal filament and the like, and also comprise special brush hair which is not popularized in manufacturing and application;

(3) the size of the brush head is as follows: the size of a brush head of the electric toothbrush is usually larger, the shape of the brush head is not smooth enough, and the space in the oral cavity of orthodontic people is smaller, so that the orthodontic devices in the oral cavity are easy to collide, the comfort of using the toothbrush by the orthodontic people is influenced, and the cleanliness of the teeth by the orthodontic people is also influenced;

(4) vibration mode and frequency of toothbrush motor: the existing electric toothbrush is mainly divided into three types, namely a mechanical type, a sound wave type and an ultrasonic type, wherein the mechanical type vibration frequency is 100Hz, 7000 times/minute, the sound wave type vibration frequency is 500Hz, 30000 times/minute, and the ultrasonic type vibration frequency is 10KHz-1000 KHz. Due to the particularity of orthodontic people, the gum and the tooth surface in the oral cavity and the friction force required by the orthodontic device are different, the applicability of the ultrasonic type to the orthodontic people is not high, and the production cost, the safety and the like of the ultrasonic type are to be examined; the mechanical type can not drive water flow to clean the interdental space due to low vibration frequency, and the mechanical type has poor effect on orthodontic people.
