Description

  The present invention relates to an electric periodontal toothbrush.

Technical background

  The electric tooth which cleans the plaque and calculus in the periodontal pocket and massages the gum while the bristle bundle reciprocates at a high speed in the long direction, and the tip of the bristle bundle opens along the side of the tooth in a fan shape. Peripheral toothbrushes are extremely effective in preventing and treating periodontal disease and removing bad breath generated from the periodontium. At the beginning of this method, a bristle bundle with a compression coil spring is attached to the tip of an electric high-pressure intermittent water flow nozzle. Then, by changing the bristle bundle into a reciprocating motion of several millistrokes with a high-pressure intermittent water flow, the inside of the periodontal pocket was cleaned and massaged with the bristle bundle tip.

1 Clinical effect of vertical electric toothbrush <Report; Professor Hisahiro Kamoi, Nippon Dental University)
2 Differences in fibroblast proliferation by repeated pressure stimulation (2003 Periodontology in Japan; Prof. Tatsuo Watanabe, Okayama University)
3 Plaque removal rate by periodontal pocket model of vertical motor toothbrush (Akiko Kuno, Nippon Dental University; Chubu Dental Show 2005) Others.

  After that, various electric toothbrushes in which the bristle bundle reciprocates change the rotational movement of the prime mover into the reciprocating movement of the bristle bundle tip, so there are a large number of parts such as gears and cranks. In addition, the production cost increased, and it did not reach the various layers that required periodontal disease prevention / treatment and periodontal bad breath removal. Cleaning after use has the inconvenience of removing the cylinder in which the bristle bundle reciprocates and washing it with water, and there is no hand to protect and straighten the bristle bundle tips and bristle bundle exposed parts when not in use. In addition, the bent part at the front of the cylinder was fixed at a fixed angle.

Means to solve the problem

Since the present invention converts the rotation of the prime mover 1 into a reciprocating motion, the first method is with a shaft attached to the sphere receivers 3a and 4a provided at the eccentric positions of the rotary plates 3 and 4 attached to the rotational shaft 2 of the prime mover 1 of the prime mover 1. A bristle bundle 8 extending from the sphere 5 to the bristle bundle tip 7 through the bristle bundle connection portion 6, the flexible bent portions 9 a and 9 b at the tip portion, the cleaning hole 10 at the rear portion, the center line of the rotating shaft 2 and the rotating disk 3 Pass through the cylinder 11 having an inclination of 20 ° to 25 ° from the intersection of the four perpendicular lines toward the front tip, and attach the cylinder 11 to the main body case 12. Therefore, when the prime mover 1 is started, a reciprocating motion of several millimeters occurs at the bristle bundle tip 7.
In the case of the second system, in order to add a rotational motion to the reciprocating motion of the bristle bundle 8, the fulcrum shaft is inserted into the fulcrum shaft through hole 13 mounted on the motor rotating shaft 2 of the motor 1 and the fulcrum shaft through hole 13 of the spring-equipped rotating disk 14. The fulcrum shaft 15 of the shaft 16 with 15 is inserted. Next, it is placed in the cylinder 11 and attached to the main body case 12 as in the first method. When the prime mover 1 is started, the bristle bundle tip 7 generates a reciprocating motion and a revolving motion of one reciprocating rotation. The angle of the bristle bundle tip 7 during use can be easily adjusted by the flexible bent portions 9a and 9b. At the end of brushing, the first method is the same, but when the cylinder 11 is pulled out a certain distance, the bristle bristles 7 are housed in the tip of the cylinder 11 and a cleaning hole 10 appears at the rear thereof, which can be easily washed with water. If left untreated, the bristle bristles 7 can be protected and straightened until the next use.

Effect of the invention

The present invention is manufactured by extremely simplifying the structure while maintaining periodontal disease prevention / treatment equivalent to or higher than that of conventional periodontal bristles, and the effect of removing periodontal bad breath. Reduces costs, reduces noise, reduces useless loads, extends power life, keeps the inside of the cylinder clean with easy cleaning, and reduces hair consumption and protects and straightens the hair. The effect lasts.
The shock absorbing spring installed at the rear of the first-type sphere with a shaft softens the impact applied to the periodontal and can make a round of comfort even with a weak periodontal. At that time, it is possible to effectively prevent and treat periodontal disease and remove bad breath by also bending the bent part of the cylinder to an appropriate angle, even for a complex periodontal region of 100 people. Therefore, the electric periodontal toothbrush with little hair tip wear and damage, low noise, and cleanness can be inexpensively provided to people in various layers who need periodontal disease prevention / treatment and periodontal bad breath removal.
The second method is unsuitable for orthodontics and other periodontals having prosthetic parts, etc., but provides a more refreshing feeling and periodontal cleaning effect for normal periodontals.

  It is a whole sectional view of the 1st method of the present invention.   It is a three-dimensional exploded view of the main part and the cylinder cleaning hole for converting the bristle bundle into the reciprocating motion of the rotary motion of the first method of the present invention.   It is an assembly sectional view of a sphere with a shaft for converting reciprocating motion into the reciprocating motion of a bristle bundle in the rotating part of the first system of the present invention.   It is a flexible bend at the tip of the cylinder.   It is a principal part exploded three-dimensional view for converting the bristle bundle of the 2nd system of the present invention into reciprocating motion and rotational motion.   It is assembly | attachment sectional drawing of the system which simplified the 2nd system of this invention.

In order to assemble the first system of the present invention as shown in the overall cross-sectional view of FIG. 1, the shaft-equipped sphere 5 of the shaft 5 with the shank-equipped rotating disk 3 and the shock-absorbing rotating disk 4 of FIG. The shaft is passed through the hole at the bottom of the sphere receiver 3a, and the sphere receiver 4a is aligned and adhered to the rear part of the sphere 5 with the shaft, and at the same time, the caulking protrusion 4b is pushed into the crimping caulking hole 3b at the counter electrode of the sphere receivers 3a and 4a. FIG. 3 is completed. Next, the shank of the rotating disk with shank 3 is inserted and fixed to the motor rotating shaft 2 of the motor 1 housed in the main body case 12, and the bristle bundle connecting portion 6 is inserted into the tip of the shaft of the spherical body with shaft 5. Next, the cylinder fitting part 11a through which the bristle bundle 8 is passed into the cylinder 11 is inserted into the fitting part 12a of the main body case, and the assembly is completed. Then, when the prime mover 1 is started, the sphere 5 with a shaft rotates eccentrically, and the bristle bundle 8 connected to the sphere 5 changes to reciprocating movement in a cylinder 11 having a certain angle, and the bristle bundle tip 7 moves several thousand times per minute. Convert to a reciprocating motion suitable for periodontal pocket cleaning and massage of several millistrokes.
In the second method, the fulcrum shaft 15 of the shaft 16 with the fulcrum shaft 15 of FIG. 5 is inserted into the fulcrum shaft through-hole 13 and the fulcrum shaft through-hole 13 of the spring-equipped rotating disk 14, and the bristle bundle connection portion 6 of the shaft 16 with fulcrum shaft. When the fulcrum shaft through hole 13 and the spring-equipped rotating disk 14 are mounted on the prime mover rotating shaft 2, the cylinder 11 through which the bristle bundle 8 is passed is mounted in the same manner as in the first method. Therefore, when the prime mover 1 is started, the bristle bundle tip 7 is rotated several thousand times per minute simultaneously with the reciprocating motion of several thousand times per minute millistroke. In the case where the second method is simplified, it is possible to connect the bristle bundle connecting portion to the connection projection of the rotary disk 18 with the connection projection 17, but to maintain the impact force of the bristle bundle tip 7, the bristle bundle 8. The overall length is shortened, so that it is possible to provide a product that is a little less convenient but convenient to carry at a lower cost.
