Title: Driving method using elasticity of tattoo machine
Inventor: WOO JAE HYUK
IPC: A61M37/00
Filed: 2018-09-11
Abstract: The present invention relates to a method for operating a tattoo machine with elasticity. According to the present invention, while a hitting force of a needle is provided by the principle of elasticity of an elastic member, the needle has the elasticity through the elastic member to store the elasticity in the elastic member when being lifted or moving back and be accelerated by restoration force of the elastic member to be restored when being lowered or moving forward such that strong hit is provided to the needle. Accordingly, the descending or forward speed of the needle is increased by the hit using elasticity to further increase hitting power of the needle, thereby facilitating infiltration of ink into skin. Moreover, the elasticity is disappeared after the needle is inserted into skin, thereby securing infiltration force of the needle without damaging the skin more than a required level and reducing time for recovering the skin due to minimization of damage. Moreover, the tattoo machine is operated by a low-power compact motor, thereby reducing manufacturing cost of the tattoo machine. Output of the motor is applied only when an assembly having the needle installed therein is lifted or moves back, and the assembly can be automatically lowered by the elasticity of the elastic member in lowering, thereby minimizing a load of the motor and increasing infiltration power of the ink even if a lower power motor than a conventional motor is used. Moreover, the low-power compact motor can be used, thereby reducing the weight of the tattoo machine, decreasing fatigue of an operator, and reducing working time due to increase in the input degree of the ink.
