Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a toothbrush head,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a toothbrush head and a toothbrush including the toothbrush, and more particularly, to a toothbrush head capable of power cleaning tooth surfaces by patterning bristles of various angles and a toothbrush including the toothbrush.

In general, effective plaque removal and gum disease prevention are necessary to maintain healthy teeth. A plaque is a sticky, transparent film that sticks to the surface of a tooth and is also called a plaque. Plaques are made up of many germs (bacteria) living in the mouth clinging to certain components in saliva, and also in teeth, prostheses, orthodontic appliances, dentures and their surroundings. Germs in the plaque not only damage the gums by creating toxins and free oxygen, but they also damage the teeth and surrounding tissues. When the teeth and gums are damaged, they become swollen, bloody, and bad breath. In particular, plaque accumulation in the periodontal pouch caused by the gap between the teeth and gums damages the bone supporting the tooth, and in the worst case, the tooth is lost.

To effectively remove such plaque, the bristles must reach all areas including the tooth surface (the surface of the tooth, the surface of the tooth), the tooth (between the neck and the tooth and the gum), and between the tooth (between the tooth and the tooth). It is important to ensure that the bristles reach all areas, such as between the tooth and the teeth (interdental), and that the bristles reach the back of the molars, especially in the deep part of the mouth, so that the brushing is done evenly. In addition, it is important to prevent gum disease by brushing the teeth with proper gum massage, or by reducing the excessive force applied to the teeth or gums to prevent damage to the gums.

However, since the teeth are arranged in a curved shape, most of the toothbrushes are made of a hard plastic material, so that the toothbrush head is not flexibly bent according to the shape of the tooth, so that the gum is subjected to excessive force do. In addition, the user may exert excessive force on the bristles to reach the teeth located deep in the mouth, and the gums may be damaged due to such excessive force.

In order to solve such a problem and to clean the tooth surface, a multi-surface cleaning toothbrush (Korean Patent Laid-Open No. 10-2006-0008231 (published on Jul. 31, 2006) And the toothbrush can not reach the inside of the molar because the tooth can be limited to only the teeth of a specific region. Therefore, the toothbrush is not suitable for universal use.

Korean Patent Publication No. 10-2006-0008231

The present invention has been made to solve the above-mentioned problems.

Another object of the present invention is to provide a toothbrush head capable of power cleaning the tooth surface and cleaning the inside of the molar.

The second bristles 12 are located in the center of the toothbrush head between the first bristles 11 and the third bristles 13. The third bristles 12 'are located at the center of the second bristles 12 and the fourth bristles 14' are located around the third bristles 13 '. The fourth bristles 14 and the fifth bristles 15 are positioned between the first bristles 11 and the second bristles 12 and between the second bristles 12 and the third bristles 13, 17 and the eighth bristles 18 are located. The sixth bristles 16 are placed on opposite ends of the second bristles 12 and are positioned adjacent to the fourth bristles 12 '' of the second bristles 12.

The first bristles 11 'and the second bristles 11' 'of the first bristles 11 are spaced from 0 to 25 degrees, more preferably between 3 and 10 degrees, in the vertical direction of the bristles 20 of the toothbrush head 10. [ The upper part of the toothbrush head 10 is tilted in an upward direction and is inclined at an angle of 1 to 20 degrees, more preferably 5 to 15 degrees in a downward direction in the horizontal direction of the kneading surface 20 of the toothbrush head 10, And the cleaning effect can be improved. The fourth bristle foil 12 "of the second bristle may be tapered at an angle of 1 to 25 degrees, more preferably 5 to 20 degrees, in the horizontal direction of the wicking surface 20 of the toothbrush head 10 . The fourth bristles 14 are also tilted from 0 to 25 degrees, more preferably from 2 to 8 degrees, in the upper direction in the vertical direction of the kneading surface 20 of the toothbrush head 10, like the first bristles 11 , Tooth surfaces and teeth which are curved in various directions and are erected downward by 1 to 20 degrees, more preferably by 5 to 15 degrees in the lower end direction in the horizontal direction of the eating surface 20 of the toothbrush head 10 have. The fifth bristles 13 'and the sixth bristles 13' 'of the third bristles 13 bristled at the bottom end of the toothbrush head 10 are positioned at 0 in the vertical direction of the bristles 20 of the toothbrush head 10, To 25 °, more preferably 2 to 8 °, in the horizontal direction of the mouthpiece 20 of the toothbrush head 10, and is preferably 1 to 20 °, more preferably 5 to 15 °, It is possible to clean up to the inner part of the molar, the front teeth and the canine, and the tooth surface can be additionally cleaned.

The first bristles 11 and the third bristles 13 may be formed to be longer than the fifth bristles 15, . The length of the bristles may be differentiated to differentiate the length of the bristles to reduce the irritation caused by the bristles to prevent the cervical portion from being worn out and also to allow the toothbrush head 10 to move up and down to clean the corners of the teeth So that the plaque can be prevented from accumulating in the teeth.
