[0027] Working principle: when in use, first pull the handle 4 to open the box door 2, then place the items to be dried on the placement plate 10 in sequence, close the box door 2 after placement, and then start the vacuum pump 8. When the vacuum pump 8 is working, the air inside the box body 1 will be extracted from the connecting pipe 2 9, so that the inside of the box body 1 reaches a vacuum state. After the vacuum, the fan 5 will be started. When the fan 5 is working, it will transport the outside air into the connecting pipe 1 6. The transported gas will be heated by the electric heating network 7. The heated gas will enter the inside of the box body 1, and then filtered by the filter element body 13. The filtered gas can dry the items on the placement plate 10. When the filter element body 13 needs to be cleaned, the pull handle 19 can be pulled downward, and the pull handle 19 drives the connecting rod 17 to slide downward inside the slide slot 15. The connecting rod 17 will compress the spring 16 during the downward sliding process. After being compressed for a certain distance, the block 18 will be away from the card slot 14. After being away, the filter element body 13 can be pulled out from the slide rail 12 for cleaning. When the device needs to be moved, the two sets of motors 21 can be started at the same time. The motor 21 drives the screw rod 22 to rotate. During the rotation, the screw rod 22 drives the long board 23 to slide downward inside the shell 20. During the downward sliding process of the long board 23, the roller 24 is driven to move downward together. After moving a certain distance, the box body 1 will be lifted, thereby making it convenient for the user to move the device.
