Lung mucus scattering blowing nozzle provided with connecting device and used for lung function examination instrument

Abstract

The utility model relates to the technical field of lung mucus scattering blowing nozzles, and discloses a lung mucus scattering blowing nozzle provided with a connecting device and used for a lung function examination instrument, which comprises a blowing nozzle, the left end of the blowing nozzle is fixedly connected with a clamping seat, a square opening pipe is inserted in the clamping seat, and the front surface of the clamping seat is provided with a fixing mechanism. And a dismounting mechanism is arranged at the top of the clamping seat. The right end of the square-opening pipe is inserted into the clamping seat through the fixing mechanism until the first sliding groove and the second sliding groove coincide and the rear end of the fixing block abuts against the interior of the second sliding groove, the square-opening pipe can be fixed, the pressing plate is pressed by hands through the disassembling mechanism, the first inclined block slides in the third sliding groove, the first inclined block moves downwards to extrude the second inclined block, and therefore the square-opening pipe can be disassembled. And a second inclined block slides in a fourth sliding groove, a movable plate is driven to move, a fixed block is driven away from the second sliding groove, then the square opening pipe is pulled out of the clamping base, and the joint between the square opening pipe and the clamping base is thoroughly cleaned.
