The specific use process is as follows:

the mask is put in from the inlet, the infrared sensor 201 senses that the mask enters and sends a feedback signal; the first gear motor 20205 drives the rotary crank 20204 to rotate, the sliding groove 20203 converts the rotary motion of the crank 20204 into the self linear motion, and further pulls the telescopic door plate 20201 to move backwards, and the first gear motor 20205 drives the crank 20204 to rotate 180 degrees and then the first telescopic door 202 is opened; the mask will drop down to the inlet transition bin 20302 due to its own weight; the first gear motor 20205 drives the crank one 20204 to rotate 180 degrees continuously, and the first expansion gate 202 is closed, so that the inlet transition bin 20302 is isolated from the external environment; thereafter, the stepping motor 20305 drives the disc 20301 to rotate 180 ° clockwise, and the positions of the inlet transition bin 20302 and the outlet transition bin 20303 are interchanged, so that the inlet transition bin 20302 is positioned right above the second telescopic door 205; the second speed reducing motor 20505 drives the second crank 20504 to rotate 180 degrees, and the second telescopic door 205 is opened; the mask in the inlet transition bin 20302 falls into the mask collecting bag 8 due to self gravity; the second gear motor 20505 then drives the second crank 20504 to continue rotating 180 ° and the second retractable door 205 is closed.
