Specific embodiment

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Embodiment one:

One end of a kind of vaporizer as shown in Figures 1 to 4, including snorkel 30, the snorkel is equipped with air inlet connecting First 70, the other end of the snorkel is equipped with exhaust joint (not shown), and the inlet suction port 70 of the snorkel is inserted with connector The hole wall 702 in hole 701, the connector receptacle is equipped with annular recess 703, and (i.e. C-C in Fig. 2 is cutd open for the cross section of the annular recess 703 Section) it is wavy.The technical solution can further enhance sealing effect and reduce the inlet suction port disengaging exhaust valve of snorkel Exhaust nozzle risk.

The hole wall of the connector receptacle is additionally provided with an annular flange 704.

Embodiment two:

It is the treatment of respiratory diseases atomization system of vaporizer application in the present embodiment, such as Fig. 1 to Figure 15 institute A kind for the treatment of of respiratory diseases atomization system shown, including oxygen feedway 10, exhaust valve 20 and atomizer 40, the atomization Device 40 is accompanied with snorkel 30, which 50 connect by the road with exhaust valve, which has exhaust nozzle 60, should Atomizer has suction nozzle (not shown), and one end of the snorkel 30, which is equipped with, docks and be connected with the exhaust nozzle 60 of exhaust valve Logical inlet suction port 70, the other end of the snorkel 30 are equipped with the exhaust joint for docking and being connected with the suction nozzle of atomizer (not shown)；

The exhaust nozzle of the exhaust valve include tube body 601, loose collar 602, fixed ring 603 and elastically deformable flexible sealing Circle 604；

The fixed ring is fixedly placed on outside tube body with respect to tube body；

The loose collar can be reciprocally placed on outside tube body with respect to tube body along the center line 605 of tube body, as shown in figure 5, solid Determine the lower section that ring 603 is located at loose collar 602；

It is in ring that the loose collar and fixed ring form one at a spacing and between the two (i.e. loose collar and fixed ring) The accommodating space 606 of shape (especially circular ring shape)；

The flexible seal ring is placed on outside tube body and is placed in accommodating space；

Squeeze the extrusion position of flexible seal ring when the loose collar is along the center line movement of tube body close to fixed ring one With switch between a releasing position far from fixed ring to discharge flexible seal ring；In the present embodiment, the flexible seal ring is in work Deformation occurs when rotating ring is in extrusion position, which restores to the original state when loose collar is in releasing position, loose collar The releasing position Shi Kecong is moved close to fixed ring along the center line work of tube body and switches to extrusion position, and loose collar is along the center of tube body Line is made to switch to releasing position far from fixed ring movement Shi Kecong extrusion position；

The inlet suction port of the snorkel has the connector receptacle 701 of the exhaust nozzle insertion for exhaust valve；

As shown in figure 15, the flexible seal ring locally protruded from when loose collar is in extrusion position outside accommodating space and with 702 phase of hole wall of connector receptacle is kept out, that is to say, that in the connector receptacle of the exhaust nozzle insertion inlet suction port of exhaust valve, and will After loose collar switches to extrusion position, flexible seal ring Local Convex can be made for accommodating space, at this point, Local Convex is empty for receiving Between flexible seal ring and the hole wall of connector receptacle mutually keep out, thus to realize sealing cooperation；

As shown in figure 13, which is integrally located in accommodating space when loose collar is in releasing position and is detached from The hole wall 702 of connector receptacle, that is to say, that in the connector receptacle of the exhaust nozzle insertion inlet suction port of exhaust valve, and by loose collar After switching to releasing position, flexible seal ring can be made to be integrally located in accommodating space, at this point, flexible seal ring is not inserted with connector The hole wall in hole contacts, i.e. the hole wall of flexible seal ring and connector receptacle is separated, thus to realize the air inlet connecting for unclamping snorkel Head, in order to which the inlet suction port of snorkel and the exhaust nozzle of exhaust valve are plugged and operated.

In the present embodiment, tube body is linearly, and the middle vacancy of tube body forms airflow channel, loose collar, fixed ring and Flexible seal ring is in circular ring shape.

In the present embodiment, flexible seal ring can be rubber seal.The tube body, fixed ring and loose collar are metalwork, The inlet suction port of the snorkel is metalwork or plastic part.

In the present embodiment, the loose collar and tube body are threadedly engaged (that is, loose collar and tube body are substantially to constitute silk Stem nut kinematic pair), it realizes to rotate loose collar and moves back and forth the loose collar along the center line of tube body.

In the present embodiment, the fixed ring and tube body can also realize fixing assembling and being threadedly engaged.

The loose collar is equipped with the canister portion 607 in a ring being placed on outside tube body, and the canister portion 607 is from loose collar 602 along tube body Center line 605 extends to fixed ring 603；

The fixed ring is equipped with the annular slot 608 being inserted into for canister portion 607, and the annular slot 608 is around tube body 601；

The canister portion 607 is inserted into annular slot 608.

The fixed ring towards the end face of loose collar 609, canister portion periphery wall 610 (periphery wall of the canister portion be located at receiving In space) and loose collar towards the end face of fixed ring 611 limit the accommodating space 606 jointly, which has The opening 612 of the one circular tube body 601 opposite with the periphery wall 610 of canister portion.The technical solution can be straight to avoid flexible seal ring Connect the movement for contacting with tube body peripheral wall and influencing loose collar with respect to tube body.

Opening 612 Local Convex of the flexible seal ring 604 when loose collar 602 is in extrusion position through accommodating space for Outside accommodating space 606.

In the present embodiment, the outer diameter D 1 of the loose collar is equal, and the outer diameter D 2 of fixed ring with the outer diameter D 2 of fixed ring Less than connector receptacle aperture D3 and so that fixed ring and connector receptacle is formed clearance fit.The technical solution can be convenient for snorkel The plug operation of the exhaust nozzle of inlet suction port and exhaust valve.Specifically, the aperture of connector receptacle can be bigger than the outer diameter of fixed ring 1mm, 2mm or 3mm etc..

The hole wall 702 of the connector receptacle is equipped with annular recess, which surround tube body setting, the annular recess Position with the position of flexible seal ring be it is corresponding, especially, the position of the annular recess and Local Convex are for accommodating space The position of outer flexible seal ring is corresponding.The technical solution can make Local Convex for receipts by setting annular recess The flexible seal ring held outside space can mutually be kept out with annular recess, and sealing effect not only can be improved, can also increase flexibility The friction contact load of the inlet suction port of sealing ring and snorkel is to reduce the exhaust nozzle that the inlet suction port of snorkel is detached from exhaust valve Risk.

The hole wall 702 of the connector receptacle is additionally provided with an annular flange 704, and the internal diameter D4 of the annular flange is less than fixed ring Outer diameter D 2, the annular flange are mutually kept out when exhaust nozzle is inserted into connector receptacle with fixed ring.The technical solution passes through setting annular Positioning action may be implemented in flange.
