Abstract
The invention discloses a negative-pressure aspirator. The negative-pressure aspirator comprises a negative-pressure cover body and a damp bottle, wherein the damp bottle is arranged in the negative-pressure cover body. The negative-pressure aspirator is characterized by also comprising a fast connector, a flow control valve, an exhaust connector and a suction inlet connector, wherein the fast connector for inputting a positive-pressure air source is arranged in the negative-pressure cover body and connected with the flow control valve through a conveying pipe, the flow control valve is connected with an inlet of the damp bottle, an outlet of the damp bottle is connected with the exhaust connector, and suction body fluid extends from the negative pressure cover body and enters the suction inlet connector of the damp bottle. The negative-pressure aspirator solves the problems that in the prior art, a mechanical device is adopted as a negative-pressure suction device which is complex in overall structure, high in manufacturing cost, larger in occupied area, inconvenient to carry and move, and inflexible in use. The invention provides the negative-pressure aspirator which is simple in structure, rapid in moving and repairing, detachable for cleaning and maintenance, high in reuse ratio and convenient to use.
