Formaldehyde adsorbent efficient spraying device capable of being pressurized repeatedly

The utility model provides a formaldehyde adsorbent efficient spraying device capable of repeatedly pressurizing, which comprises a pressurizing mechanism, and the pressurizing mechanism comprises a box body, a round pipe, a first one-way valve, a motor and an L-shaped pipe; a round pipe is arranged on the right side of the box body. A motor drives a connecting rod to move through a cross rod, the connecting rod drives a vertical plate to move to compress a spring, the vertical plate drives a circular block to move through a square rod, the circular block exhausts gas in a circular pipe into a connecting box, and the connecting box exhausts the gas into a box body through a second one-way valve. The motor continuously works to gradually discharge outside gas into the box body to increase the pressure intensity in the box body, the manual valve is reversely rotated, under the action of the pressure intensity in the box body, the formaldehyde adsorbent in the box body is sprayed to the plate through the spray h
