The gear 602 rotates to drive the rotating column 603 to rotate, and the support ring 606 rotates to drive the extrusion ring 618 to rotate. The movable column 624 and the third piston 626 move up and down under the extrusion of the extrusion ring 618 and the support of the first compression spring 623. The fourth piston 702 and the fifth piston 703 move up and down as a whole. The fifth piston 703 repeatedly draws the calcium hydroxide at the bottom of the mixing barrel 1 into the channel 609, and the calcium hydroxide is sprayed out through the spray hole 610.

The electric telescopic column 616 extends, the moving ring 617 moves upward, the moving ring 617 and the extrusion ring 618 move upward, the clamping column 607 leaves the clamping groove 619, and the second piston 620 moves upward. The two first pistons 612 move, and the scraper 613 moves accordingly and sticks to the inner wall of the mixing barrel 1. When the rotating column 603 rotates, the scraper 613 automatically scrapes off the calcium hypochlorite on the inner wall of the mixing barrel 1, making the discharge effect more complete.
