Pressure control method and system introduced into beauty instrument

Abstract

The pressure control method comprises the following steps that the pressure P of a gas tank of the beauty instrument is detected, and whether the pressure meets a threshold value P1 and a first derivative of the pressure value P or not is judged; judging whether the first-order derivative reaches a threshold value A or not and whether the first-order derivative is in a normal operation state or not, maintaining the current situation of the air compressor, starting the stepping motor to operate for N steps, and entering a nursing state; in the nursing process, the actual pressure P is further detected, the relation between the actual pressure P and the threshold value P1 is judged, the first-order derivative threshold value of the detected pressure P is further judged, and the rotating speed of the air compressor is increased or decreased according to the judgment result. According to the method, the threshold range P1 of the operating pressure P is set, first-order derivative judgment is conducted on the operating pressure, a threshold value is set for the first-order derivative, and the rotating speed of the air compressor is controlled; different first-order derivative threshold values are set according to different pressures, accurate control is carried out, it is guaranteed that the pressure and flow in the gas tank are stable, it is guaranteed that the gas supplementing time is minimized, and rapid use is achieved.

Description

technical field [0001] The invention belongs to the technical field of beauty instrument control, and in particular relates to a pressure control method and system for introduction into a beauty instrument. Background technique [0002] With the improvement of people's living standards, consumers have higher and higher requirements for beauty and skin care, and their professional level is also improving. Therefore, the demand for traditional hand-applied skin care products is also changing. They hope to penetrate quickly and have a high penetration rate to the basal layer of the skin. Therefore, the traditional manual method cannot be satisfied. Some existing products are imported by means of instruments, but they often cannot reach The reason is that the effect of promoting penetration is small, or the use of mechanical atomization does not meet the requirements of skin introduction. [0003] The existing high-pressure gas is used to atomize the medicine, and the gas flow ...
