Title:
LOW-TEMPERATURE OXYGEN PLASMA SKIN TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/050957
Kind Code:
A1
Abstract:
Disclosed is a low-temperature oxygen plasma skin treatment device, comprising a control host, a piezoelectric ceramic plasma generator, and a digital voltage driver. The digital voltage driver and the piezoelectric ceramic plasma generator are in signal connection with the control host. An oxygen tank communicates with an air nozzle by means of an air pipe. An air valve is arranged on the air pipe. The control host can control the opening and closing of the air valve. The air nozzle has an annular shape and is sleeved on the piezoelectric ceramic plasma generator. The air nozzle is covered with a treatment head. There is a cavity in the treatment head. An air jet hole of the air nozzle communicates with the cavity. A plurality of air outlet holes communicating with the cavity are formed on the end face of the treatment head that is in contact with the skin. An output electrode of the piezoelectric ceramic plasma generator is located in the cavity and is close to the end face. There is a gap between the output electrode of the piezoelectric ceramic plasma generator and the end face. The present device improves the safety of use of skin treatment devices.
