Abstract
A needle tip mounted on a skin care device and the skin care device are provided to prevent a proximity effect. The needle tip includes a case, a holder disposed in the case and reciprocating in a vertical direction, and a plurality of needle electrodes disposed in the holder, a current being applied to the plurality of needle electrodes. The plurality of needle electrodes include a first group of needle electrodes and a second group of needle electrodes to which the current is applied at mutually different times.
Claims9
A needle tip mounted on a skin care device, the needle tip comprising:
- a case;
- a holder disposed in the case and reciprocating in a vertical direction;
- a plurality of needle electrodes disposed in the holder,
- wherein each of the plurality of needle electrodes has an equal height,
- wherein the plurality of needle electrodes are arranged in at least one of one or more rows and one or more columns on a plane perpendicular to the vertical direction,
- wherein the plurality of needle electrodes include a first group of needle electrodes and a second group of needle electrodes,
- wherein the needle electrodes of the first group are configured to apply first currents to a target point area of a skin at a first time, and the needle electrodes of the second group are configured to apply second currents to the target point area of the skin at a second time, which is different from the first time, such that the first group and the second group are configured to alternatively apply the first currents and the second currents to the target point of the skin, and
- wherein the needle electrodes of the first group and the needle electrodes of the second group are connected with one power source in parallel;
- and
- a switch configured to:
- be operated such that power from the power source is alternately applied to the needle electrodes of the first group and the needle electrodes of the second group;
- and
- be operated such that high frequency energy configured to be provided to a reference area of the target point per reciprocating drive period is divided by alternative oscillating and is provided to the reference area of the target point.
