2 to 5, the vane member 20 is made of a twisted shape of the body on the plate formed in the form of a wave having a protruding period in the thickness plane in the longitudinal axis of the twist, the wave protruding convex It is formed into a surface, and divided into the first vane 21 and the second vane 22 on the basis of the turning point of the wave, the length of the first vane 21 and the second vane 22 based on the total length It is preferable to form the ratio in a ratio of 5: 5.

Here, the starting point thickness t1 of the first vane 21 is a starting point of the second vane 22, which is the end point of the first vane 21, based on the body length direction of the vane member 20. The thickness t3 and the end point thickness t5 of the second vane 22 are equal to each other, the protruding point thickness t2 of the first vane 21 and the protruding point thickness of the second vane 22 ( It is preferable to form t4) equal to each other.

Accordingly, the thicknesses of the first vane 21 and the second vane 22 forming the vane member 20 are formed to have a protruding period in the form of a convexly protruding wave, thereby forming the inside of the mixing tube 30. A relatively large mixing space and a relatively small mixing space are alternately formed along the longitudinal direction in the space, so that the impression material and the hardener conveyed along the mixing tube 30 are surface-linked by the vane member 20. Extruded while mixing in motion.

Here, the surface-linked motion mimics peristaltic motion, which is a muscle motion that allows food to be evenly mixed in the fire extinguisher by changing the thickness of the thickness of the vane member 20, wherein the thickness surface of the vane member 20 has a protruding period. Impression material extruded through the mixing tube 30 by the vane member 20 by alternately forming a relatively large mixing space and a relatively small mixing space in the inner space of the mixing tube 30 as a wave shape And hardener are mixed with each other in a surface-linked motion.

At this time, the vane member 20 is divided into a first vane 21 and a second vane 22 based on the turning point of the wave, as shown in FIG. 2, the first vane 21 and the second vane ( Only one of the upper and lower surfaces of 22) protrudes convexly, or as shown in FIG. 3, only one of the upper and lower surfaces of the first and second vanes 21 and 22 is reversed. It can be formed convexly protruding.

A plurality of protruding periods of the 21 and second vanes 22 may be formed, and the protruding thicknesses of the first and second vanes 21 and 22 may be different from each other.

In addition, the vane member 20 according to another embodiment of the present invention with reference to Figure 6 may be a plurality of individual pieces are assembled with each other to form a mixing tip, the vane member 20 provided as individual objects is a user By the optional combination of may be assembled in a row on the front of the connector portion 10 to form a mixing tip.

In this case, only one of the upper and lower surfaces of the first vane 21 and the second vane 22 is formed to protrude convexly, or the upper surface of the first vane 21 and the second vane 22. Any one of the vane members 20 are formed to protrude convexly in any one of the lower side surfaces, or protrude convexly on both the upper and lower surfaces of the first vane 21 and the second vane 22. Dogs can be assembled in various combinations to achieve mixing tips.

Therefore, the dental mixing tip according to the present invention minimizes the section through which the impression material and the hardener are not mixed as it is, and thus the mixing efficiency is increased, and maintains the uniform quality by continuous repeated mixing or conveying, as well as the vane member. Since the thickness of the first vane 21 and the second vane 22 is formed in the shape of a wave having a protruding period, the mixing efficiency of the impression material and the curing agent is improved compared to the prior art, thus shortening the overall length of the mixing tip. This allows miniaturization of the device as well as minimizing the amount of material remaining on the mixing tip.

Again, the mixing tip is formed in the front center of the connector portion 10, the shaft 12 having a cross section '+' toward the front, wherein the shaft 12 is perpendicular to the front of the connector portion 10 or It is preferable to be located between two coupling holes 11 horizontally, preferably formed integrally extending from the front surface of the connector portion 10, but not limited to the end of the shaft 12 is the connector It may be fixed by screwing to the front of the portion (10).

When the shaft 12 is coupled to the connector portion 10 by screwing, the length of the shaft 12 may be variously applied.

And the mixing tip includes a hollow mixing tube 30, the hollow mixing tube 30 is inserted into the shaft 12 through the rear end, the rear end of the mixing tube 30 is the connector It is fixedly coupled to the portion (10).

Accordingly, the shaft 12 is positioned at the center of the mixing tube 30, and the impression material and the hardener extruded toward the front of the connector 10 are guided to the mixing tube 30 with the shaft 12 as an axis and extruded forward. do.

In the present invention, the mixing tube 30 is described as a separate configuration, but is not limited thereto, and the shaft 12 may be integrated in the front surface of the connector unit 10, and may be integrally extended toward the front. .

In addition, a connection shaft portion 23 is formed at the center of each of the plurality of vane members 20 provided as individual objects, and a '+'-type through hole is formed at the center of the connection shaft portion 23 to form the vane member ( 20 is fitted to the shaft 12 through the through hole of the connecting shaft portion 23 is assembled.

At this time, the vane member 20 fitted to the shaft 12 is assembled in a state in which rotation is interrupted, and a plurality of the vane members 20 are accommodated in a row by the user's assembly combination in the mixing tube 30 to form a mixing tip. (12) A fastener is coupled to the foremost end to prevent the vane member 20 from being pulled out of the shaft 12, and to allow both ends of the shaft 12 to be fixed on a horizontal line. 12) prevents eccentricity on either side.

In addition, the mixing tip according to another embodiment of the present invention is coupled to one of the plurality of vane member 20 is idle to the shaft (12) to the shaft (idle), by the extrusion pressure of the impression material and the hardener to the vane An acting friction may cause the shaft 12 to rotate about its axis.

For example, when the vane member 20 is provided to rotate idling, a bearing having a hole of '+' is formed in the connecting shaft 22 of the vane member 20, and the vane member 20 includes the shaft ( 12) Idle about axis.

In this case, a bushing or a washer is disposed between the vane members 20, so that frictional resistance between the connecting shaft 23 of the vane member 20 and the connecting shaft 23 of the other vane member 20 adjacent to the vane member 20 is minimized. It can be easily rotated.

Therefore, the vane member 20 is rotated about the shaft 12 by the friction with the impression material and the hardener extruded forward by the bearing provided in the connecting shaft portion 23, the resistance force according to the extrusion pressure is reduced The durability of the mixing tip is improved.
