Next, powder is placed inside the powder storage box 1, and the powder storage box 1 is sealed by the first sealing ring 401 and the top cover 402. Then, the control plate 202 drives the rotating rod 201 to rotate, and the fan blade 203 rotates accordingly to stir the powder. Then, the air bag 403 is pressed to release the powder to the brush 503 for use. Finally, after the powder storage box 1 is inverted, the rotating plate 301 drives the inner core 302 to rotate. When the indicator 304 moves to the left or right, the through grooves opened on the outer surface of the inner core 302 and the outer shell 303 are staggered, thereby sealing the lower part of the powder storage box 1. Then, the clamping rod 7 connects the brush cover 8 to the powder storage box 1, thereby protecting the brush 503.
