Rotational linear reciprocating device and applicator including same

Abstract

The present invention relates to a rotational linear reciprocating device and an applicator including the same. The rotational linear reciprocating device of the present invention comprises: a driving unit which is rotated by a motor; a rotating unit which is installed on one surface of the driving unit and transmits rotating force of the driving unit to an applicator; and a reciprocating unit which is installed on the other surface of the driving unit, converts the rotating force of the driving unit into a linear reciprocating motion, and transmits the same to the applicator. The driving unit includes: a driving plate in which the rotating unit and the reciprocating unit are individually installed on both surfaces; and a driving belt which is installed on an edge of the driving plate, and transmits driving force of the motor to the driving plate by frictional force by being touched to a motor shaft of the motor.

Description

technical field [0001] The present invention relates to a rotary linear reciprocating device and an applicator including the device, and more particularly, to a rotary linear reciprocating device and an applicator including the device that performs linear reciprocating motion while rotating the applicator , so that the cosmetics can be finely and uniformly applied to the object to be applied without accumulation. Background technique [0002] In general, people use various applicators to apply cosmetics to the skin in order to make themselves look healthy and beautiful. [0003] As a type of applicator, mascara is used to make eyelashes appear longer and darker. [0004] As such a mascara, there is a manual mascara in which a user directly rotates a brush to apply eyelash makeup. [0005] In the case of conventional manual mascara, if the user is not skilled in eyelash makeup, not only it is difficult to curl the eyelashes, but also the eyelashes cannot be curled upwards, ...

AI Technical Summary

Problems solved by technology

[0008] However, in the conventional electric mascara, the brush is only rotated by an electric motor or a reducer motor, so that the mascara tends to go to one side of the eyelashes or accumulates.

[0009] At the same time, in the past, it was difficult to apply the mascara on the left and right sides of the eyelashes, so it was necessary to move the brush from side to side to apply mascara to the eyelashes, so it was troublesome

[0010] In addition, conventional electric mascara rotates the brush regardless of external pressure, so when external pressure such as sticking to the skin occurs, the electric motor is overloaded, so there are problems such as damage to the electric module and damage to the applicator.
