Description

Oral cavity tooth cleaner

Technical Field

The invention relates to an oral tooth cleaner, in particular to an oral tooth cleaner which is contained in the mouth without hands.

Background

At present, people clean teeth in daily life by adopting a mode of brushing teeth in the morning and at night, which effectively solves the problem of cleaning teeth, but has the following defects:

1. the teeth cleaning can not be finished when the patient leaves the hand, so that the patient with hand injury and inconvenient movement can hardly finish the teeth cleaning by the bedridden people.

2. The degree of freedom is low. The postprandial tooth brushing is a necessary requirement for protecting teeth, and because toothpaste foam overflows and drips during tooth brushing, the tooth brushing needs to be carried out by bending down and lowering the head at a fixed place, so that the tooth brushing is easily limited by environmental conditions and cannot be carried out in time for cleaning the teeth.

3. Different tooth brushing modes and different tooth cleaning effects are achieved. The correct tooth brushing mode requires that a certain angle is kept for brushing from top to bottom or from bottom to top, and the mode has good tooth cleaning effect and high requirement and is not easy to master. The incorrect tooth brushing mode is to brush back and forth transversely, most consumers adopt the mode, the tooth cleaning effect is poor, gum and tooth root injuries are easily caused, and the inner side of teeth is not easy to clean.

4. The toothbrush is large in size, inconvenient to carry and waste materials.

The design makes full use of the force of the oral teeth to clean the teeth, realizes tooth brushing without hands, achieves small volume, is simple and easy to learn, is convenient to use, saves time and labor, and creates a new tooth cleaning mode.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

provides an oral tooth cleaner, which comprises a rectangular plane bracket, a left crank arm, a right crank arm, a roller, a chest expander, a left protective cover and a right protective cover. The left protective cover and the right protective cover are respectively fixed at the left end and the right end of the rectangular plane support, and the left crank arm and the right crank arm are oppositely fixed on the central point of the middle opening of the rectangular plane support in the protective covers, so that the two crank arms can rotate in the left-right direction. A group of rollers is longitudinally arranged at the upper end of the left crank arm, and a group of rollers is longitudinally arranged at the lower end of the left crank arm; and a group of rollers are longitudinally arranged at the upper end of the right crank arm, and a group of rollers are longitudinally arranged at the lower end of the right crank arm. The bottom of the left protective cover is provided with a spring exerciser which is connected with the right crank arm, the bottom of the right protective cover is provided with a spring exerciser which is connected with the left crank arm, and under the action of the spring exerciser, the rollers at the upper end and the lower end of the left crank arm and the rollers at the upper end and the lower end of the right crank arm are in a closed state. The oral cavity tooth cleaner is held in the mouth, so that the rollers at the upper ends of the crank arms are contacted with the upper teeth, and the rollers at the lower ends of the crank arms are contacted with the lower teeth. The size of the opening of the roller at the upper end of the crank arm can be determined according to the size of the occlusal surface of teeth. The opening of the roller at the upper end of the front tooth thin crank arm is small, and the opening of the roller at the upper end of the rear tooth wide crank arm is large. When the upper and lower teeth are engaged, the rollers at the upper ends of the crank arms are stuck on the two sides of the teeth to roll up and down to clean the two sides of the teeth. When the upper and lower teeth are separated, the force of the tongue oral cavity drives the oral cavity tooth cleaner to move left and right in the mouth, and the occlusal surfaces of the teeth are cleaned through the rolling of the roller at the lower end of the crank arm. The oral cavity tooth cleaner can be turned over in the mouth at will, thereby realizing the cleaning of the upper and lower teeth.

Due to the adoption of the structure, the oral cavity tooth cleaner is small in size, and can clean teeth by utilizing the force of the oral cavity teeth when being contained in the mouth, so that the teeth can be brushed without hands. The teeth can be cleaned anytime and anywhere no matter the user walks, sits and sleeps, learns, meets, watches TV and plays mobile phones. The oral tooth cleaner is simple and easy to learn, and can be used conveniently by the old, the patient, the disabled hand, the disabled person and the bedridden person. The oral tooth cleaner saves materials, is convenient to carry, and saves time and labor.
