Dispenser nozzle for high pressure injection

A dispenser nozzle for high pressure injection, applied to a dispenser which includes a driving part 10, a coupling part 20 and a nozzle part 30, such that a tappet 100, which carries out vibration motion and has a leading end portion 101 formed in a conical shape, is mounted on the lower end of the driving part 10 so as to be exposed and inserted into the nozzle part 30 through the coupling part 20, and the nozzle part 30 is provided with a nozzle 120 on the bottom surface thereof, the nozzle 120 comprising:

• a funnel-shaped accommodation part 121 formed for maintaining a predetermined gap from an outer circumferential surface of the leading end portion 101 of the tappet 100;
• a funnel groove 122 formed in the center of a bottom surface 121a of the funnel-shaped accommodation part 121 such that the leading end portion 101 of the tappet 100 is inserted into the funnel groove 122 by a predetermined length;
• an injection hole 123 penetratingly formed in the center of the funnel groove 122;
• and
• an injection groove 124 formed in the inclined plane of the funnel groove 122 at one side of the bottom surface 121a of the funnel-shaped accommodation part 121 such that liquid to be dispensed is introduced into the funnel groove 122.

• three first groove portions 132 having a circular shape and formed of a predetermined depth on the upper end portion of a main body 131 so as to be adjacent to each other;
• a funnel groove 133 formed of a predetermined depth down to a bottom surface 134 in the center portion thereof among the first groove portions 132 such that the leading end portion 101 of the tappet 100 is inserted into and comes into contact with the funnel groove 133 by a predetermined length;
• an injection hole 135 penetratingly formed in the center of the funnel groove 133;
• and
• a second groove portion 136 formed in the inclined plane of the funnel groove 133 at one side of each of the first groove portions 132 such that liquid to be dispensed is introduced into the funnel groove 133.

• two first groove portions 142, 142 having a circular shape and formed of a predetermined depth on the upper end portion of a main body 141 so as to be adjacent to each other;
• a funnel groove 143 formed of a predetermined depth down to a bottom surface in the center portion thereof between the two circles of the first groove portions 142, which are adjacent to each other, such that the leading end portion 101 of the tappet 100 is inserted into and comes into contact with the funnel groove 143;
• an injection hole 144 penetratingly formed in the center of the funnel groove 143;
• second groove portions 145, 145 having a circular shape and formed of a predetermined depth inside the first groove portions 142;
• and
• a third groove portion 146 formed in the inclined plane of the funnel groove 143 at one side of each of the second groove portions 145, 145 such that liquid to be dispensed is introduced into the funnel groove 143.
