Description

Teeth cleaning device with three-dimensional bristles arranged at equal angular intervals of less than 180 degrees along the circumferential direction

The present invention relates to a dental cleaning device, in particular, a row of bristles on the dental cleaning device will be arranged at an equal interval angle of less than 180 degrees along the circumferential direction to form three-dimensional bristles for users to rotate the dental cleaning device , And can smoothly remove the residue and tartar from the teeth near the gums out of the tooth cleaning device.

According to the American Academy of Periodontal Diseases, patients with periodontal disease are twice as likely to suffer from coronary artery disease as compared with people without periodontal disease. The main reason is that the bacteria of periodontal disease can flow along the blood, while in The formation of fatty plaques on the coronary artery lumen that provides heart nutrition causes the arterial wall to thicken and cause thrombosis. Therefore, chronic inflammation caused by gum disease has been associated with cardiovascular diseases such as heart disease, blood vessel blockage and stroke. Relevance; in addition, adults with gingivitis (gingival swelling, bleeding) perform poorly on memory and other cognitive tests compared to adults with healthy gums and teeth. Health is closely related.

In addition to the aforementioned health factors, maintaining good oral hygiene is also one of the essential requirements for maintaining the quality of life. After all, healthy teeth can make people maintain full self-confidence when social chatting, which in turn increases the charm and style of speaking. At present, most people keep their mouths clean by brushing their teeth and gargle. Although the "toothbrush" has a good effect of removing plaque on the cheeks, lips, tongue and occlusal surfaces of the human body, but Interdental teeth of adjacent teeth As far as scale is concerned, toothbrushes cannot achieve a complete cleaning effect. Therefore, people usually use a tooth cleaning tool that can pass through the gaps between teeth (or interdental, interdental) to effectively clean the interdental tartar between adjacent teeth.

The flossing tools that are commonly used today (especially the aforementioned interdental tartar cleaning of adjacent teeth) are mostly floss sticks and interdental brushes. Generally speaking, the conventional floss stick includes a floss fixing part and a A grip portion, wherein the floss fixing portion is U-shaped, and two corresponding ends are fixedly connected to both ends of a floss, and the grip portion is fixedly connected to the floss fixing portion for a user Hold, so that the user can take the grasping part of the conventional dental floss stick after the meal and put the dental floss fixing part into the entrance, so that the dental floss on the dental floss fixing part can be used Scrape off the tooth surface and tartar between teeth. However, because the dental floss is tight and straight on the conventional dental floss rods, the user must completely penetrate the dental floss between the teeth to remove the debris and tartar between the teeth. The dental floss is too small and the dental floss is not easy to enter In the case of teeth, the residue and tartar near the gums are not easy to be removed, and the user is also prone to excessive force, which causes the tight floss or hard floss fixation to hit the gums, causing bleeding of the gums.

In view of the above, in view of the aforementioned lack of use, people will also choose to use the interdental brush to clean the teeth. In addition, the existing interdental brush is a small brush head with a volume similar to a toothpick, but with bristles. The bristles of the intermediary brush penetrate into the tooth gap to easily remove the residue and tartar near the gums from the tooth gap with the bristles on the tooth. At the same time, the elastic bristles can be used to massage the gum back and forth. It can not only remove the residue and tartar of the teeth near the gums, but also promote the blood circulation of the gums by massage, avoid the bleeding and bleeding of the gums, and achieve the purpose of oral health care. Since neither the dental floss stick nor the interdental brush can simultaneously achieve the effect of completely removing the residue between the teeth and massaging the gums, for users who pay attention to oral health, they must still use the dental floss stick and the interdental brush in order to achieve Oral health care that completely removes residues between teeth and massages gums Effect, because the dental floss bar or interdental brush is a small product, so when the user goes out, if you need to carry and store the independent dental floss bar and interdental brush separately, it will inevitably cause user distress and inconvenience Sex.

In addition to the aforementioned problems, the applicant has found that most of the existing interdental brushes are made by injection molding. In order to facilitate the demoulding, the existing interdental brushes are mostly made of the same material, and the bristles on it It is generally set in two rows, and the interval angle of the bristles in each row is 180 degrees (that is, symmetrically arranged), so that the two molds can be directly separated from top to bottom. The aforementioned interdental brush structure is easy to cause the following problems: (1) The interdental brush can provide a certain strength, is convenient for the user to hold, and can be smoothly inserted between the interdental teeth, especially when the interdental teeth are small, making the interdental brush The material of the brush is hard, and it is easy to cause gum injury; if it is made of a material with a lower hardness, the interdental brush is easily bent and deformed by the user's grip, which is unfavorable; (2) Generally speaking, the teeth are close to the gums The gaps at the place are more likely to leave residues and tartar, and the gap between two adjacent teeth will have two aforementioned gaps. However, because the interval between the two rows of bristles between the brushes is 180 degrees, when one of them When the row of bristles cleans the gap between one tooth root and gums, the other row of bristles does not work, reducing the convenience of cleaning.

Therefore, how to improve the aforementioned problems to provide users with a better user experience has become an important issue in the industry's urgent research and development improvement, and it is also an important topic for the present invention to discuss here.

In view of the fact that there are still imperfections in the use of conventional dental floss sticks and interdental brushes, the inventor finally developed and designed a tool of the present invention after long-term hard research and experiment The teeth cleaning device with three-dimensional bristles arranged at an equal interval angle of less than 180 degrees along the circumferential direction is expected to solve the aforementioned conventional problems effectively by the advent of the present invention and be favored by users.

An object of the present invention is to provide a tooth cleaning device with three-dimensional bristles arranged at an equal interval angle of less than 180 degrees along the circumferential direction, including a grip section, a floss fixing section and a bristle section, wherein the grip The segment can be held by the user's fingers, one end can be connected to the side edge of the dental floss fixing segment, the other end can be connected to the bristle segment, and the dental floss fixing segment will be U-shaped, and its phase A floss is provided between the corresponding two support arms.
