Description

 Constant pressure type toothbrush structure Technical field

The invention relates to a constant pressure type detached toothbrush structure, in particular to a brushing habit which can automatically detect that the brushing force is controlled within a certain range, so that the brushing force is appropriately safer and more comfortable, and can help to develop an optimal force.

Background technique

According to the medical journal, develop good oral hygiene and clean habits, and regular dental examinations to ensure the health of teeth and gums. However, most people think that oral cleaning can be done with a brush, it can clean the teeth, and can effectively shorten the brushing time, which is a very serious misconception.

In fact, brushing too much force will cause the tooth enamel to wear, so that the tooth surface loses protection, causing tooth bacteria to invade, easily causing tooth decay, loose teeth, roots worn or even broken. Brushing too hard is also likely to cause the gums to shrink and shrink. Plaque is more invasive, and inflammation of the gums produces lesions.

In recent years, dental research generally believes that the correct way of brushing should be done with a soft brushed toothbrush between the gums and the teeth, so that it can be safely cleaned and avoid damage to the teeth. And even if you use the correct brushing method, the brushing force should be moderately sized, not too hard, otherwise it will also cause damage to the teeth.

In addition, brushing too much force will also shorten the service life of the toothbrush. It can be used normally for 1~2 months. Under strong over-force, the bristles will be separated in a short time, and the teeth and gums may be used. Directly cause more serious damage.

Unfortunately, most people start to brush their teeth from an early age. The strength of brushing their teeth is not strong. As the age increases, the habit of brushing your teeth is still the same. The more you brush for a long time, the more the gums will accumulate, the more the gums will shrink. The essence of exposure becomes a sensitive tooth. When eating ice and eating hot, it is painful. Even when special anti-sensitive toothpaste is used, it can only achieve the effect of relieving the symptoms, and it is impossible to completely solve the problem. The wrong brushing habits lead to the teeth not being taken care of. From the time of youth, the teeth are constantly being treated and filled, and the middle and old ages are full of dentures, even if the food is currently unavailable.

technical problem

In fact, the most effective method of dental preservation is to improve the basic structure of the toothbrush. It is the best way to prevent the correct brushing habits and strengths. However, the new generation of toothbrushes, although having a variety of different elastic lengths and bristles, as well as a special shape of the elastic brush bar buffer design, but does not have the function of self-detecting brush force. Other advanced toothbrushes have self-detecting brush power, but their structural design is not good enough, and the practical functions are not perfect, and further improvement is needed.

Technical solution

The main object of the present invention is to provide a constant pressure type toothbrush structure, comprising: a brush head, a rod body is disposed under the bottom to connect a handle; and the joint forms a joint portion between the handle and the rod body, the joint The part has a connecting fulcrum and a movable joint, wherein when the rod body is pressed, the movable joint will temporarily dislocate the offset, so that the rod body and the handle are staggered, so that the brush head runs to the disabling position and is unfavorably brushed;

Preferably, the rod body and the handle of the brush head can be separate independent pieces to form a joint portion, and the rod body, the handle and the joint portion can be further integrally formed for manufacturing, even for better use effect. , an elastic sleeve may be added on the outside of the joint portion (actually, it is not necessary to add);

In this way, the brushing force is appropriately safer and more comfortable, and the brushing force can be automatically detected within a certain range, which can help to develop the best brushing habit.
