The modern industry generates a large amount of byproducts, and the byproducts such as dust, waste gas and the like are directly discharged into the external environment, so that the environment is seriously influenced, and even the health of people is threatened. Aiming at the problems, the embodiment of the invention provides a jet-suction tool and a jet-suction device, which can adsorb and filter byproducts such as industrial dust, waste gas and the like, thereby reducing the pollution degree to the environment, and the specific implementation scheme is as follows:
the injection and suction tool provided in this embodiment includes an injection and suction gun 100, where the injection and suction gun 100 includes an air inlet 111, an air outlet 112, and an air inlet 113; the air inlet 111 is connected with the air supply assembly 200 through a pipeline; the air outlet 112 is provided with a filter assembly 400 which can filter the waste gas; a suction head 300 for sucking exhaust gas is arranged at the suction port 113, and the suction head 300 is communicated with the suction port 113 through a pipeline; when the air supply assembly 200 supplies high-pressure air to the gun 100, the suction head 300 can suck external exhaust air into the gun 100 and filter the exhaust air through the filter assembly 400.
The jet-suction tool provided in this embodiment adopts a venturi tube principle, and high-pressure gas is introduced into the jet-suction gun 100 through the gas supply assembly 200 to generate negative pressure therein, specifically, the gas inlet 111 of the jet-suction gun 100 is communicated with the gas supply assembly 200 through a pipeline, the gas outlet 112 is connected with the filter assembly 400, and the gas suction port 113 is communicated with the suction head 300 through a pipeline.
