Abstract
The invention belongs to the technical field of aspirators, and particularly discloses a pneumatic negative pressure aspirator which comprises a shell, an upper cover is fixedly mounted at the top end of the shell, a water pumping opening is formed in the top end of the upper cover, spray pipes are fixedly mounted on the two sides of the bottom end of the upper cover, and water storage tanks are arranged at the two ends of the front side of the shell. The top of the water storage tank is connected with the bottom of the upper cover, and the spray pipe is located at the top end of an inner cavity of the water storage tank. By adopting a small and exquisite shell structure and modular design, the equipment can be flexibly moved to various departments for use, fixed installation is not needed, the problem that existing equipment is poor in use flexibility is solved, and the equipment has the effects of being convenient to move and suitable for being used in multiple scenes.
