Accurate detection device for air leakage of facial mask packaging bag based on Bernoulli principle

Abstract

The invention relates to the technical field of cosmetics, and discloses an accurate detection device for air leakage of a facial mask packaging bag based on Bernoulli principle. The accurate detection device comprises a base, the detection device comprises a photoresistor, a hanging column and feathers, an illumination lamp corresponding to the detection device is arranged on the outer side of anextrusion plate, an arc-shaped metal sheet is arranged in a first magnet, a second magnet comprises a triangular groove and a metal ball, a coil is arranged on the left side of the interior of a detection box, and a first annular metal sheet and a second annular metal sheet are arranged inside a fixed shaft. The illumination lamp is driven to move downwards through the extrusion plate, an air leakage opening of the edge of the mask bag blows the feathers in the detection device, the feathers with light weight is blown up, the resistance in the photoresistor is rapidly reduced, the coil connected in series with the photoresistor is energized, the magnetic field generated by the coil pushes the second magnet on the left side to move upwards, and the problem of low detection precision of anexisting facial mask air leakage detection device is solved.

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...
