[0011] Preferably, the motor is a stepping motor so as to accurately control the spray dosage.

[0012] The beneficial effect of a non-invasive water light instrument provided by the utility model is that the non-invasive water light instrument has a reasonable design, a simple structure, a small size, is easy to use, and can realize fully automatic and precise control of the spray dosage. In actual operation, compressed air is delivered to the nozzle through the trachea, and the liquid in the syringe bottle is also delivered to the nozzle. The liquid is atomized by compressed air and sprayed out through the nozzle through the nozzle and the nozzle, and contacts with human skin, so as to realize non-invasive delivery of the essence. In addition, the spray metering can be accurately controlled by the motor. In actual use, the spray dosage is controlled by the matching gap between the telescopic ejector and the nozzle. When the spray dosage needs to be increased, the telescopic ejector retracts, the gap with the nozzle becomes larger, and the dosage increases.
