On the other hand, the case 130 is provided with a core 133 in the front opposite to the needle assembly 120, the solenoid operation part 131 is provided inside the back of the core (133). The core 133 has a pin through hole 133a formed in the central portion and an outer spiral portion 133c formed in the front so that it is spirally coupled to the inner spiral portion 135 formed in the core coupling groove 114 of the connector 110 . is composed The solenoid operation unit 131 includes a bobbin 131b parallel to the central portion of the case 130 in the form of a pipe, a coil 131a wound around the bobbin 131b, and the bobbin 131b provided inside. The plunger 131c and one side are inserted into the pin through hole 133a of the core 133 and the other side is composed of a plunger operation pin 132 coupled to the tip of the plunger 131c. In addition, the core 133 is integrally formed with a plunger guide 133b in the center of the rear side to ensure straightness when the plunger actuating pin 132 moves.

The bobbin 131b has a circular support plate 136 having a diameter corresponding to the inner diameter of the case 130 by standing vertically inside the case 130 and fixing the bobbin support plate 136 in the center of the bobbin ( A bobbin support hole 136a having an inner diameter corresponding to 131b) is formed so that the tip of the bobbin 131b is inserted and supported in the bobbin support hole 136a.

The plunger 131c has a circular cross-section and is formed in the form of a pellet having an outer diameter corresponding to the inner diameter of the bobbin 131b, and is provided parallel to the inside of the bobbin 131b. And on the same center line as the plunger 131c, the rear end of the plunger operating pin 132 is fixed to the center of the tip of the plunger 131c, and the front end of the plunger operating pin 132 is the pin through hole 133a of the core 133. It is inserted into and meets the rear end of the needle-integrated needle pin 123 of the needle assembly 120. At this time, the needle-integrated needle pin 123 receives the elastic force of the silicone spring 124a and pushes the plunger operation pin 132 and the plunger 131c to the rear bobbin support 137 inside the bobbin 131b to elastically support it. . Accordingly, the plunger operation pin 132 and the needle-integrated needle pin 123 protruding toward the rear of the needle assembly 120 always maintain a butt-but-adhering state inside the pin through hole 133a of the core 133. and the movement of the plunger actuating pin 132 is guided so that it can go straight without losing its center by the aforementioned plunger guide 133b. It is formed to be inclined to the side, and the plunger 131c has a guide insertion portion 134 having a shape corresponding to that of the plunger guide 133b at its tip.

On the other hand, the plunger operation pin 132 may be integrally formed with the plunger 131c or may be separately manufactured and assembled. When assembling, a flange 132a is integrally formed at the rear end of the plunger operating pin 132, and a flange insertion groove 132b corresponding to the flange 132a is formed at the front end of the plunger 131c, but the flange ( It is formed somewhat deeper than the thickness of 132a, and an O-ring 132c having a slightly larger diameter than the flange insertion groove 132b is provided on the outside of the front plunger operation pin 132 of the flange 132a. Accordingly, when the flange 132a of the plunger operation pin 132 is inserted into the flange insertion groove 132b of the plunger 131c and the O-ring 132c is forcibly inserted into the flange insertion groove 132b, the flange insertion groove 132b The larger outer diameter O-ring (132c) is closely attached to the inside of the flange insertion groove (132b) to support and fix the flange (132a) of the plunger operation pin (132) to the flange insertion groove (132b) of the plunger (131c). do. And as described above, since the plunger operation pin 132 and the needle-integrated needle pin 123 always maintain a butt-but-adherent state with each other by the silicone spring 124a, the plunger operation pin 132 is firmly attached to the plunger 131c. ) is not necessarily fixed. Here, undescribed reference numeral 131 denotes an air hole, 139 denotes a connector housing, 140 denotes an end cap, and 140a denotes a lead wire.

In the present invention configured as described above, a power line (not shown) is connected to the connector housing 139 through the end cap 140 to receive power, and the power is transmitted to the coil 131a through the lead wire 140a. . Then, the operation is performed using the wrist while holding the grip part 115 of the connector 110 by hand. At this time, since the skin contact ring 125b of the needle guide 125 first touches and presses the skin, the operation is performed, so the resistance of the skin Because the displacement is not large, it is possible to accurately inject the dye to a desired depth, and since the front of the handpiece 100 is supported, a more stable treatment can be performed than the treatment in a state where the handpiece 100 is separated from the skin. has

Then, after injecting the dye through the dye injection hole 122a of the needle cap 122, when the operation mode is entered, the current flows in the coil 131a and is cut off, so that the needle 123a moves repeatedly and strikes the skin. As a result, the operation is performed. To explain this in more detail, first, when a current flows in the coil 131a, an attractive force is instantaneously applied to the plunger 131c by electromagnetic force, so that the plunger 131c instantaneously moves toward the needle assembly 120. Accordingly, the plunger operation pin 132 overcomes the elastic force of the silicon spring 124a and forcibly pushes the needle-integrated needle pin 123, so that the needle 123a moves forward, and the current is cut off in the coil 131a. By the return force of the silicone spring 124a, which was forcibly stretched on the lower surface, the needle-integrated needle pin 123 pushes the plunger operation pin 132 in the opposite direction, so that the plunger 131c is also returned to its original position by repeating the return to the original position of the needle 123a. Repeated movement can be made.

Here, the characteristic is that the response speed of the needle (123a) is made immediately and quickly when the plunger (131c) is operated by the electromagnetic force of the coil (131a), and the immediate and quick response of the needle (123a) is the needle (123a) during the procedure. ) means that the probe force that penetrates the skin momentarily increases. This increase in probing force can minimize the displacement of the skin due to the resistance of the skin when the needle, that is, the needle, is pierced into the skin, so that the pigment can be accurately injected at the desired depth. Since it is operated in a state of being, it can be seen that the displacement hardly occurs. To this end, the present invention uses a silicone spring (124a), which has lower elasticity and coefficient of restitution than a conventional metal spring and is sensitive to external forces, and a slightly increased silicone when assembling the needle assembly 120 to the connector 110. By the elastic force of the spring 124a, the plunger operation pin 132 and the needle-integrated needle pin 123 are abutted to each other and kept in close contact with each other inside the core 133.

That is, the present invention uses a silicon spring 124a that has lower elasticity and coefficient of restitution than a metal spring and is sensitive to external force, and when the plunger 131c advances by the electromagnetic force of the coil 131a, the plunger operates The force is transmitted to the needle-integrated needle pin 123 through the pin 132. At this time, the plunger operation pin 132 and the needle-integrated needle pin 123 are abutted to each other and are in close contact with the elastic force by the silicone spring 124a. By maintaining the state, the transfer of force to the needle (123a) can be made immediately and quickly.

In addition, in the present invention, the plunger operation pin 132 and the needle-integrated needle pin 123 configured to be separated from each other are buttted to each other in a state in which the outside is in close contact with each other inside the pin through hole 133a of the core 133, the plunger operation pin When the 132 is operated, the guide insertion part 134 of the tapered plunger 131c is guided by the plunger guide 133b of the core 133, so that the needle 123a requires the accuracy of instantaneous hitting on the skin. Straightness can be ensured.

In the above, the handpiece for a tattoo device according to the present invention has been specifically described, but this is only a description of the most preferred embodiment of the present invention, the present invention is not limited thereto, and the scope is determined by the appended claims become and limited In addition, it will be clear that any person skilled in the art will be able to make various modifications and imitations according to the description of the specification of the present invention, but this also does not depart from the scope of the present invention.
