An accurate detection device for air leakage of mask packaging bags based on Bernoulli's principle

Abstract

The invention relates to the technical field of cosmetics, and discloses a precise detection device for mask packaging bag air leakage based on Bernoulli's principle, including a base, the detection device includes: photosensitive resistors, hanging posts and feathers, and the outer side of the extrusion plate is set There is an illuminating lamp corresponding to the detection device, the inside of the first magnet is provided with an arc-shaped metal sheet, the second magnet includes: a triangular groove and a metal ball, a coil is provided on the left side of the inside of the detection box, and the inside of the fixed shaft is provided with a first An annular metal sheet and a second annular metal sheet. Drive the illumination lamp to move down through the squeeze plate, the air leak on the edge of the mask bag blows up the feathers in the detection device, the light feathers are blown up, the resistance in the photoresistor decreases rapidly, and the coil connected in series with the photoresistor When energized, the magnetic field generated by the coil pushes the second magnet on the left to move upwards. This structure solves the problem of low detection accuracy of the existing mask air leakage detection device.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an accurate detection device for air leakage of facial mask packaging bags based on Bernoulli's principle. Background technique [0002] Cosmetics have the function of beautifying and beautifying the skin, which can enhance the elasticity and vitality of the skin. Regular use can make people young and beautiful. Mask is an indispensable part of skin care. Daily skin care products cannot supply the moisture and nutrients that are lost in a large amount every day. Depending on the age, there should be different times of mask every week to replenish nutrients for the skin. Sticker-type masks must be lying down Apply, because the mask has weight. When the mask is completely attached to the skin, it will shape the skin. If you stand or sit, the skin will sag due to gravity. [0003] In the process of mask production, processing and manufacturing, there will be a small number of mas...
