FIG. 4 is a perspective view of a suction tip according to a first embodiment of the present invention. Sectional view showing the inner surface of the cover 30. Fig.

5 is a perspective view showing the shape of the through hole 32 of the cover 30 in the suction tip according to the first embodiment of the present invention.

1 to 5, the suction tip according to the first embodiment of the present invention includes a suction portion and a cover 30. As shown in Fig.

Here, the suction unit is a component that directly performs suction, and includes a tip 10 and a suction pipe 20 in this embodiment. The tip 10 is provided at an end of the suction pipe 20, and a suction hole 12 is formed.

A separate suction device is connected to the opposite side of the suction pipe 20, so that foreign matter or the like can be sucked through the suction hole 12.

Unlike the present embodiment, the suction unit is a suction tip in which the cover 30, the tip 10 and the suction pipe 20 are integrally formed, or the end of the suction pipe 20 itself serves as a tip The present invention can also be applied to a suction tip having no separate tip. That is, the suction unit may be formed in various forms.

In this embodiment, the tip 10 has a circular section. And includes a front surface having a predetermined area and a side surface extending rearward from the periphery of the front surface. That is, the tip portion 10 may be formed as a conical or cylindrical shape that is entirely cut.

The suction hole 12 is formed to extend from the front surface of the tip portion 10 to the side surface and includes a front suction area 12a and a side suction area 12b. A plurality of the suction holes 12 are radially formed from the front center of the tip portion 10.

Needless to say, the shapes of the tip portion 10 and the suction hole 12 may be variously formed in addition to the present embodiment.

Also, in the present embodiment, the tip 10 and the suction pipe 20 are made of synthetic resin, plastic or plastic foam. Alternatively, the tip 10 and the suction pipe 20 may be made of metal.

At this time, the through hole 32 may be formed to have an area larger or smaller than the area of the suction hole 12. [

The cover 30 and the through-hole may be formed in various forms. For example, the through-hole may be formed over the entire area of the cover 30, or may be formed only in a region corresponding to the suction hole 12. [

In the case of this embodiment, the cover 30 has a shape in which a through-hole 32 having a predetermined shape is formed individually in the entire area of the cover 30. Specifically, in the present embodiment, the through-hole 32 includes a first through-hole 32a corresponding to the front surface of the tip 10, and a second through-hole 32a corresponding to the suction hole 12 of the side surface of the tip 10. [ And a third passage hole 32c formed in an area of the side surface of the tip 10 where the suction hole 12 is not formed.

In this embodiment, such a through-hole 32 has a size enough to allow foreign matter such as a lime material and a dental restoration to pass therethrough, thereby solving the problem that the through-hole 32 is clogged by foreign matter .

In addition, the number of the through-holes 32 may be smaller or larger than that of the present embodiment, and may be various shapes such as an ellipse or a rectangle as well as a circular shape. The through hole 32 may be formed over the entire area of the cover 30 or may be formed only in a region corresponding to the suction hole 12.

3, the inner surface of the cover 30 is spaced apart from the outer surface of the tip 10 and forms a spacing space 35 therebetween.

The reason for doing this is to prevent the suction holes from being clogged by the region where the through hole 32 is not formed in the side surface of the cover 30. [ Also, the problem that the airflow is dispersed by the spacing space 35 and the oral mucosa is adsorbed to the through-hole 32 can be solved.

4, the cover 30 includes an inner protrusion 34 protruding from the inner surface of the cover 30 and contacting the outer surface of the tip 10 to provide a supporting force.

Accordingly, even if the spacing space 35 is formed between the cover 30 and the tip 10, the inner protrusion 34 stably fixes the cover 30 to allow the cover 30 to freely move Can be prevented.

Meanwhile, in the present embodiment, the periphery of the tip 10 is formed to be larger than the circumference of the suction pipe 20 to form the step 11. The cover (30) includes a latching protrusion (36) for catching the step (11).

The engaging projection 36 of the cover 30 is engaged with the step 11 in an interference fit manner so that the cover 30 can be stably fixed to the tip portion 10. [

On the other hand, as shown in FIG. 5, the peripheries 33 of the through holes 32b and 32c may be rounded. This is to prevent the foreign object being sucked from being interfered by the through holes 32b and 32c. Although the first passage hole 32a is not shown in FIG. 5, the circumference 33 may be applied to the first passage hole 32a.

In this embodiment, the cover 30 is detachably formed with the tip 10 and can be freely separated, combined, and rotatable. Needless to say, the cover 30 may be adhered to or adhered to the tip 10.

The cover 30 may be integrally formed with the tip 10 and the cover 30, the tip 10, and the suction pipe 20 may be integrally formed.
