The inner wall of each pump air chamber 14 is connected with a piston plate 18 in a sealing sliding mode, the side wall of each piston plate 18 is fixed with a push block 16, each piston plate 18 and the inner wall of the corresponding pump air chamber 14 are jointly fixed with a return spring 17, each push block 16 penetrates through the side wall of the pump air chamber 14 and abuts against a rotating block 15 inside the corresponding rotating chamber 13, the rotating block 15 rotates to collide with the push block 16 continuously, and the return springs 17 are combined, so that the piston plates 18 do reciprocating motion.

The side wall of each pumping air cavity 14 is provided with an air supplement hole 23 in a penetrating way, the side wall of the uppermost pumping air cavity 14 is provided with a backflow pipe 21 in a penetrating way in an inserted way, the other end of the backflow pipe 21 is communicated with the inside of the exhaust pipe 7, the side walls of the other pumping air cavities 14 are provided with air supplement pipes 20 in a penetrating way in an inserted way, the side wall of the ventilation box 1 is provided with an outer air flow pipe 19 in a penetrating way in an inserted way, and each air supplement pipe 20 is communicated with the inside of the outer air flow pipe 19 in a penetrating way through the side wall of the outer air flow pipe 19; the return pipe 21, the plurality of air supply pipes 20 and the plurality of air supply holes 23 are internally provided with one-way valves to ensure the effective pumping of airflow, and the outer airflow pipe 19 is internally provided with a filter screen for filtering dust in the air outside the chamber;

when the airflow drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the rotating block 15 to rotate, the rotating block 15 intermittently collides with the pushing block 16 in the rotating process, the pushing block 16 pushes the piston plate 18 to move under the extrusion, so that the return spring 17 extends, when the pushing block 16 is dislocated with the rotating block 15, the piston plate 18 is reset under the elastic force of the return spring 17, and the pushing block 16 is reset at the same time, so that the pushing block 16 drives the piston plate 18 to do reciprocating piston motion in the rotating process of the rotating block 15;

the pump air cavity 14 connected with the return pipe 21 can draw the air flow discharged outside by the exhaust pipe 7 through the return pipe 21 during operation, and most of the air flow floats on the upper part along with the air flow due to more negative ions entering the interior of the purifying box 3 and almost no gravity action on the negative ions which are not combined with the impurity particles, so that even if the air flow deflects, the negative ions cannot completely enter the deflection tank 6, and part of the negative ions flow out along with the air flow, and different from the charged particles formed by combining the impurities, the negative ions have certain weight, are located at the middle and lower positions during moving, and can effectively enter the deflection tank 6 during deflection;

from this it can be known, the air current in the exhaust pipe 7 of back flow pipe 21 extraction, there will be a certain amount of anion, consequently, the pumping air cavity 14 that corresponds is to the air current of discharging in the workshop, also will be mingled with a certain amount of anion, thereby make the inside air in workshop obtain the anion and purify, also can improve staff's in the workshop health simultaneously, make the workshop internal environment obtain further promotion, and the pivot 11 that the pumping air cavity 14 that back flow pipe 21 corresponds, it is located the top position, the effect that receives wind-force and assaults is worst, consequently, the rotational speed of the pivot 11 that corresponds is limited, thereby can not cause the excessive emission of anion in to the workshop, safe effectual anion that utilizes.
