When the hair scraps in the dust bag 316 collect a lot of hair scraps and need to be cleaned, install a new dust bag 316 on the air inlet 314 on the side of the left side plate 310 through the positioning ring 317, and then push the left side plate 310 in the opposite direction to install the plate 30 8 Move in the opposite direction. When the ear plate 313 on the side of the left side plate 310 contacts the velvet discharge cylinder 305 and stops moving, the positions of the left side plate 310 and the partition plate 311 are on the same vertical plane as the positions of the shells on both sides of the velvet discharge cylinder 305. The left side plate 310 and the partition plate 311 are sealed with the velvet discharge cylinder 305 through the sealing gasket 312. The new dust bag 316 enters the velvet discharge cylinder 305 to replace the previous dust bag 316 to work. The previous dust bag 316 is removed from the velvet discharge cylinder 305 as the mounting plate 308 moves in the opposite direction, making it easier to clean it. During the replacement process, the exhaust fan 307 does not need to be paused, and will not interfere with the existing work, making the replacement of the dust bag 316 more convenient.
