The present invention relates to a toothbrush used for brushing teeth and gums together with toothpaste, and as shown in FIG. It is an oral care toothbrush with multiple functions.

First, the toothbrush handle 10 according to the present invention is formed in an ergonomic bar shape so that the user can hold it with at least one hand and handle it in a desired direction, as shown in FIG.

As shown in FIGS. 2 and 3 , the toothbrush handle 10 is formed with a screw groove 11 and a receiving groove 12 .

The screw groove 11 is depressed with a predetermined diameter and depth at the center of the upper end of the longitudinal side so that the screw shaft 24 of the toothbrush head 20 to be described later is fastened.

The receiving groove 12 is recessed to a predetermined diameter and depth at the center of the lower end of the longitudinal side so that the shaft 32 of the interdental brush 30 to be described later is inserted.

Here, an interdental groove recessed to accommodate the interdental pin 33 planted in the shaft 32 is further formed at the center of the receiving groove 12 .

Then, the toothbrush head 20 according to the present invention rubs the teeth and gums to wipe foreign substances, and is fastened to the upper end of the toothbrush handle 10 to be replaceable as shown in FIG. 1.

As shown in FIGS. 2 and 4, the toothbrush head 20 is formed of a head body 21, a brush 22, a connecting rod 23, and a screw shaft 24.

The head body 21 is formed as an elliptical plate, and is formed in a size suitable for oral cavity for adults and children.

The brush 22 is planted on the front of the head body 21 so that mohair divided into bundles protrudes in a predetermined pattern and height.

Here, as shown in the drawing, the brush 22 may be formed with different heights at the top and bottom, or may be formed at the same height.

The connecting rod 23 extends and protrudes from the lower end of the head body 21 to induce fastening with the toothbrush handle 10.

The connecting rod 23 has a length such that an end thereof is exposed to the outside of the oral cavity even when the head body 21 is maximally entered into the oral cavity.

That is, the connector 23 prevents or minimizes the entry of the toothbrush handle 10 into the oral cavity during brushing, thereby protecting the toothbrush handle 10 from germs.

The screw shaft 24 protrudes to a predetermined length from the center of the lower end of the connecting rod 23 and is closely engaged with the screw groove 11.

That is, the toothbrush handle 10 and the toothbrush head 20 can be quickly and conveniently replaced by the screw groove 11 and the screw shaft 24.

Above all, contamination such as water spots can be prevented as the penetration of water into the threaded groove 11 or the joint is blocked due to the tight compression fastening.

At this time, a plurality of ventilation holes 25 are formed in the head body 21 according to the present invention at each location where the brush 22 is planted, as shown in FIG. 4 .

These ventilation holes 25 induce a flow of air between the brushes 22 to accelerate drying of the brushes 22 .

Here, the upper scraper 41 and the lower scraper 42 are disposed spaced apart from each other in the vertical direction, and are formed round in an arc shape when viewed from the front.

That is, since the upper and lower scrapers 41 and 42 are formed in an arc shape, foreign substances (white) attached to the bottom of the tongue are removed in a centrally collected state according to the movement of scratching from the inside to the outside of the tongue.

Therefore, foreign substances detached from the tongue do not remain on the bottom of the tongue and can be removed more quickly and cleanly.

Here, the upper scraper 41 is preferably protruded to a length higher than the height of the lower scraper 42 or, conversely, the lower scraper 42 to protrude to a length lower than the height of the upper scraper 41.

That is, the bottom of the tongue in a state in which the mouth is open is inclined downward from the inside of the mouth to the outside.

Therefore, if the height difference between the upper and lower scrapers 41 and 42 is set according to the angle of the bottom of the tongue, the toothbrush handle 10 can also take a comfortable posture inclined downward toward the mouth.

Here, the upper and lower scrapers 41 and 42 preferably protrude at an angle at an angle so as to increase friction with the bottom of the tongue and improve the separation of foreign substances.

On the other hand, in the toothbrush handle 10 according to the present invention, one or more guide grooves 13 recessed in a semicircular shape are formed at the upper end where the screw groove 11 is located, as shown in FIG. 5 .

In addition, the toothbrush head 20 has guide protrusions 26 engaged with and constrained by the guide grooves 13 at the lower end of the connecting rod 23, respectively.

These guide grooves 13 and guide protrusions 26 prevent the toothbrush handle 10 and the toothbrush head 20 from coming loose while ensuring a sense of unity with each other at the right position.

Here, the toothbrush handle 10 is formed with a sliding groove 14 that is recessed in an arc shape so as to communicate from one side of the guide groove 13 to the outside.

The sliding groove 14 prevents rotational interference with the guide protrusion 26 while the screw shaft 24 is completely fastened to the screw groove 11.

In addition, the guide groove 13 and the guide protrusion 26 guide the rotation so that they are closely engaged with each other at the correct position.

Here, the sliding groove 14 is preferably formed to a depth lower than that of the guide groove 13 to prevent loosening.

In addition, it is preferable to form the guide groove 13 toward the outside so that the depth gradually decreases according to the pitch of the screw groove 11 and the screw shaft 24.

In addition, as mentioned above, the toothbrush handle 10 according to the present invention is preferably ergonomically formed so as to provide excellent usability.

That is, the toothbrush handle 10 is knitted with a hand portion 10a, a finger portion 10b, and a waist portion 10c as shown in FIG. 6 .

The hand part 10a is formed convexly in an elliptical shape so that the ring finger and the little finger are wrapped around the user's palm.

The finger portion 10b extends at an inclined position toward the rear on the upper side of the hand portion 10a.

The finger portion 10b is formed convexly in an elliptical shape smaller than the hand portion 10a so that the user's thumb and forefinger come into close contact with each other back and forth.

The waist portion 10c is concave in a streamlined shape so that the user's middle finger is wrapped between the hand portion 10a and the finger portion 10b to prevent slide separation.

Soft rubber pads 15 are attached to the hand parts 10a to the waist part 10c to prevent slipping on each part of the user's fingers.

Here, the rubber pad 15 of the hand portion 10a is preferably formed in a waveform shape to match the curve of the finger or in a fine mohair shape to provide excellent grip.
