Description of the Related Art Screw holes for mounting solenoid valves, control valves, etc. have a hole bottom 102 that does not penetrate, as shown in FIG. 4, and a screw hole 201 as shown in FIG. Some have no bottom and penetrate through to communicate with the flow path 202. When cleaning after removing sealing material such as sealing tape or tight stick from the screw part, air is blown with an air blower at the screw hole 101 with the hole bottom 102 shown in FIG. 4 to remove the sealing material, etc. As shown in FIG. 5, since the sealing material cannot be dropped into the flow path 202 in the threaded hole 201 penetrating therethrough, it is necessary to suck up the sealing material by air suction.

Must be discharged to the outside. At this time, as shown in FIG. 7, the worker attaches the suction pipe 401 to the end surface of the ejector 306 of the air suction device 301 on the suction hole 311 side with the screw 402 and grips the grip portion 302 of the air suction device 301. Then, pressing the operation button 309 causes compressed air to flow from the intake passage 307 into the air chamber 305 and the ejector 306, and compressed air is ejected from the end face of the ejector 306 on the side of the discharge hole 310, so that the ejector 306 sucks the screw hole 201. Clean the inside. When attempting to stop the ejection of compressed air, loosen the operation button 309 to block the intake passage 307 and stop the inflow of compressed air into the air chamber 305.

On the other hand, when the switching valve is switched to the open state, the compressed air from the intake passage passes through the ejector by the operation of the operation button, so that a suction action is generated, and the outside of the opening of the air passage on the intake hole side of the ejector. Air is inhaled. In this way, by closing or opening the switching valve, compressed air from the intake passage can be ejected from the opening of the air passage on the ejector suction hole side, or air can be sucked from the outside.
