Working principle:
before the storage part 120 is not assembled, the transverse body 1411 falls to the bottom in the inner pipe groove 112B under the action of gravity, then the lug 131 is pressed to be contracted in the outer pipe groove 121A, then the storage outer pipe 121 is inserted into the inner pipe groove 112A, the holding part 200 is connected with the detection outer pipe 111, the storage outer pipe 121 can be connected with the detection outer pipe 111 in a threaded mode or can be clamped in a clamping mode or the like, after the connection, the storage outer pipe 121 stays in the inner pipe groove 112A under the limit of the holding part 200, the lug 131 enters the superposition position of the inner pipe groove 112B and the outer pipe groove 121A under the action of the elastic force generated by the connecting spring 133 when the storage outer pipe 121 is inserted into the inner pipe groove 112A, once the lug 131 with a wedge-shaped structure is inserted into the bottom of the transverse body 1411 and is jacked up, a gap is generated between the air blowing head 140 and the detection outer pipe 111 and the detection inner pipe 112, the mouth biting on the air blowing head 140 can breathe through the gap, during blowing, because the flow speed of the blown air is fast, and under the guidance of the blowing channel, the air blown by the mouth directly enters the inner channel 112A, and at this time, the inner tube groove 112B is sealed by the vertical body 1412, so that more air flows into the cavity in the storage inner tube 122 through the gap between the sealing disc 130 and the opening, after the blowing detection is finished, the mouth presses the blowing head 140 to approach the detection outer tube 111, or manually pushes the detection outer tube 111 to the blowing head 140, so that the two relatively move to each other, the blowing head 140 drives the connecting rod 142 to move inwards, meanwhile, the transverse body 1411 is pressed to slide downwards along the inner channel 112A, the transverse body 1411 drives the lug 131 to synchronously move inwards, the lug 131 drives the sealing disc 130 to attach to the storage inner tube 122, at this time, the support plate 134 needs to be separated from the inner wall of the storage inner tube 122 by means of the downward pressing force, so as to release the constraint of the support plate 134 on the sealing disc 130, the sealing disk 130 can then be fitted over the opening of the storage inner tube 122 to seal the opening.
When the storage part 120 is taken down, the holding part 200 is firstly detached, at this time, the storage outer tube 121 drives the lug 131 to fall below the outer tube groove 121A under the action of gravity, at this time, part of the storage outer tube 121 is exposed below the inner tube 112A, and then the storage outer tube 121 can not actively fall off under the limit of the lug 131, so that the subsequent operation is convenient, that is, the storage outer tube 121 is forced by hands to be pulled out from the inner tube 112A, at this time, the sample of the gas blown out from the mouth is completed by utilizing the inner cavity of the storage inner tube 122, and further, the secondary detection of the gas blown out from the mouth at the current time in the later stage is realized.
In this way, during the process of pulling out the storage outer tube 121, the protrusion 131 is contracted into the storage outer tube 121 by the inclined surface, so that the storage outer tube 121 is pulled out smoothly.
