A gear 603 is slidably connected to a gear rod 604 on one side of the piston of the hydraulic chamber 601. A half of teeth are arranged on the gear 603, and the gear 603 is meshed with the gear rod 604 through the teeth. When the transmission rod 602 rotates, it cooperates with the gear 603 fixedly connected to the transmission rod 602.

When the gear rod 604 moves under the action of the gear 603, the hydraulic chamber 601 slidably connected to the piston of the gear rod 604 is matched. The gear rod 604 moves so that the pressure inside the hydraulic chamber 601 increases, which makes the hydraulic chamber 601 and the hydraulic chamber 601 with the hydraulic chamber 601 connected to the hydraulic chamber 601 move. The push rod 605 slidably connected to the piston of the pressure bin 601 moves accordingly, and the movement of the push rod 605 causes the mixing plate 607 fixedly connected thereto to move; similarly, when the area without teeth on the gear 603 rotates to the gear rod 604, the gear rod 604 loses its restriction, and the gear rod 604 can move and reset under the action of the spring 606 fixedly connected thereto, so that the mixing plate 607 can move and reset, and the mixing plate 607 can move back and forth, so that the smoke inside the spray box body 200 can be mixed and vibrated, thereby improving the mixing effect of the device and avoiding the occurrence of uneven mixing.
