Referring to these drawings, the teeth whitening apparatus 100 according to the first embodiment of the present invention, the teeth whitening body unit 200 and the teeth whitening body unit 200 is located in close proximity to the teeth to perform the teeth whitening Is connected to and in close contact with the head to support the tooth whitening body unit 200, but includes a head close unit 300 is provided to be adjustable in length.

In general, tooth whitening by a whitening agent is a method of irradiating light after applying hydrogen peroxide, which is used as a whitening agent, to a tooth, and may have a high whitening effect in a relatively short time.

In other words, when whitening teeth, a whitening agent containing hydrogen peroxide is applied to the surface of the tooth. Hydrogen peroxide is an unstable substance and tries to stabilize itself, thereby decomposing other substances.

Here, the hydrogen peroxide is oxidized by the property of self-stabilization, and whitening of the teeth is possible due to the oxidation of hydrogen peroxide.

However, when the teeth are irradiated with light through a light irradiator using a conventional tooth whitening device, the tooth whitening subject is not only inconvenient because it is necessary to sit or lie in bedding for a long time while the tooth whitening is running, There was a problem of being inefficient in terms of time because no other actions could be performed during the teeth whitening process.

In order to solve this problem, the tooth whitening apparatus 100 according to the first embodiment of the present invention is connected to the head contact unit 300 which is worn on the head, so that the whitening unit 200 is connected to the head. A body such as an arm and a leg can be used freely, whereby the effect of allowing teeth whitening simply and easily will be described in detail below.

1 and 2, the tooth whitening body unit 200 is provided to be close to the teeth to perform tooth whitening. That is, after the whitening agent containing hydrogen peroxide is applied to the teeth to be whitened, the tooth whitening body unit 200 irradiates light toward the teeth to whiten the teeth.

In addition, the tooth whitening body unit 200 may be connected to and supported by the head contact unit 300 through the connection unit 400. That is, the tooth whitening body unit 200 may be coupled to one side of the connection unit 400, and the head contact unit 300 may be coupled to the other side of the connection unit 400.

1 and 2, the connection unit 400 may be ergonomically designed to correspond to the shape of the head and face, and may be provided to be flexibly flexed as necessary using a flexible wire. have.

In addition, the tooth whitening body unit 200 may be detachably coupled to the connection unit (400). That is, since the tooth whitening body unit 200 is located close to the oral cavity of the human body, it may need to be cleaned for hygiene. If the tooth whitening body unit 200 is used for personal use at home, the tooth whitening body unit 200 may be easily washed. Can be.

Or, when used in the hospital, if you need to use different tooth whitening body unit 200 for a number of teeth whitening subject, it may be replaced by separating the tooth whitening body unit 200 from the connection unit 400.

That is, the tooth whitening body unit 200 may be provided to be coupled to or separated from the connection unit 400 through detachment.

To this end, referring to Figures 4 to 6, the tooth whitening body unit 200 may be provided with a coupling ring 210 having an opening 211, the connection unit 400 is hooked to the coupling ring 210 Coupling hook engaging unit 410 may be provided.

4 and 5, the coupling ring 210 may be coupled to the tooth whitening body unit 200 so as to protrude to the outside of the tooth whitening body unit 200, and the coupling ring locking unit 410 is provided. The coupling unit 400 may be coupled to the inside, and the coupling ring 210 may be introduced into the coupling unit 400 so as to be caught by the coupling ring locking unit 410.

That is, the tooth whitening body unit 200 can be coupled to the connection unit 400 through the engaging ring 210 is caught by the engaging ring engaging unit 410.

Here, referring to Figure 6 (a) to Figure 6 (c), the engaging ring engaging unit 410 may be configured to include a engaging ring engaging member 411, the engaging ring engaging member elastic unit 412. .

Referring to Figure 5, the engaging ring engaging member 411 is disposed in the interior of the connection unit 400, the sawtooth-shaped projection 416 may be formed to be caught in the engaging ring 210. That is, the tooth-shaped protrusion 416 is caught in the opening 211 of the coupling ring 210 so that the tooth whitening body unit 200 can be coupled to the connection unit 400.

Then, the engaging ring engaging member elastic unit 412 is connected to the engaging ring engaging member 411 to provide an elastic force to the engaging ring engaging member 411.

That is, after the sawtooth-shaped protrusion 416 included in the engaging ring engaging member 411 is caught in the opening 211 of the engaging ring 210 (see Fig. 6 (a)), the engaging ring engaging member 411 By pressing the coupling ring 210 may be separated from the protrusion 416 (see FIG. 6 (b)), when the coupling ring 210 is separated from the protrusion 416, the coupling ring engaging member elastic unit 412 is completed. 6) provides an elastic force to the engaging ring engaging member 411 to restore the engaging ring engaging member 411 to its original shape (see FIG. 6 (c)).

5 and 7, when adjusting the length of the tooth whitening body unit 200, in order to control the length adjusting range, the coupling ring 210 may have an unevenness 212, and the teeth whitening body The inside of the unit 200 is coupled to the main body engaging projection plate 220 is formed with the engaging projection 221, the engaging projection 221 formed on the main body engaging projection plate 220 is uneven 212 of the coupling ring 210 It may be provided to be able to latch and release.

That is, the tooth whitening body unit 200 may be disposed excessively close to a predetermined range or more from the tooth due to the difference in the size and shape of the head of the tooth whitening subject. Since this may occur, in order to prevent this, the tooth whitening body unit 200 is coupled to the connection unit 400, it may be provided to be adjustable in length from the connection unit 400.

Here, referring to FIG. 7, the main body locking projection plate 220 may be provided such that a locking protrusion 221 protruding from one side of the flat plate is formed. In this case, the main body locking projection plate 220 may have an elastic force. Can have

That is, when the locking projection 221 is pressed, the main body locking projection plate 220 is elastically contracted. When the pressing force is removed, the locking projection 221 is restored to its original position by the elastic recovery force.

By the way, when the tooth whitening body unit 200 is adjusted in length from the connecting unit 400, the locking projection 221 is pressed or released by the unevenness 212 of the coupling ring 210, the main body locking projection plate ( The locking protrusion 221 formed on the 220 is repeatedly caught and released by the unevenness of the coupling ring 210 by the elastic force, thereby controlling the length adjustment range.

On the other hand, the tooth whitening body unit 200 may be provided to enable the vertical position adjustment in the vertical and horizontal direction and close to the position close to the teeth relative to the tooth.

That is, since the structure, arrangement, and shape of the teeth are different according to the tooth whitening subject, the tooth whitening body unit 200 may be moved in the vertical direction or the left and right directions to adjust the position according to the teeth of each tooth whitening subject.

And, according to the tooth whitening state of the tooth whitening subject, the position of the proximity can be adjusted so that the tooth whitening body unit 200 is disposed closer to or closer to the teeth from the position.

For example, when the distance between the teeth whitening body unit 200 and the teeth is less than 30 [mm], the effect of the teeth whitening is increased, in particular, the distance between the teeth whitening body unit 200 and the teeth is 15 [ mm] when the excellent effect of the teeth whitening can be seen through the experimental results.

8 and 9, the tooth whitening body unit 200 may be configured to include an LED unit 250 for irradiating light to the tooth, and a heat dissipation unit 260 connected to the LED unit 250. .
