Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an electric cosmetic tool that uses an electric motor to dispense a core cosmetic such as lipstick or eyeshadow.

(Prior Art) Conventionally, this type of cosmetic tool dispenses cosmetics by gripping and rotating the container, or by pressing a button protruding from the rear end of the container.
In both cases, this was done by direct manual operation.

(Problems to be Solved by the Invention) Therefore, the manual operation is mainly performed with both hands, so for example, when applying makeup while holding a mirror in one hand, the operation must be performed while holding the mirror.
Not only could the cosmetics not be dispensed sufficiently, but there was also a risk that the mirror or cosmetics container would fall. Also, during makeup, the core of the cosmetic is worn out as makeup is applied, so the feeding operation is repeated over and over again. Adjustment was extremely troublesome. Furthermore, the structure for this purpose is complicated, and failures are likely to occur, making it difficult to form a cartridge.

In view of the above-mentioned conventional problems, this invention is an attempt to solve these problems. By using an electric motor to dispense or insert cosmetics, it can be easily operated with one hand, and the amount dispensed can be controlled. To obtain an electric cosmetic tool with a simple structure and low cost, which can finely adjust the amount of cosmetics, replace the cosmetics in a cartridge, and use the cosmetics container for a long period of time.

(Means for Solving the Problems) As a means for achieving this, the present invention provides for attaching a cartridge body containing cosmetics in a replaceable manner to a shaft body, providing an electric device in the shaft body, and providing the electric device with an electric device. A feeding mechanism is provided between the cosmetic material in the cartridge and the cosmetic material in the cartridge body, and a mechanical or It is equipped with an electrically operated clutch device.
