12, the pipe venthole 12 that is located by connecting penetrates through the pipe 2 that is located by connecting, and the gas for the pipe 2 that is located by connecting passes through the pipe outlet that is located by connecting
The outflow of hole 12 is located by connecting outside pipe 2, and when cut-off diaphragm 5, which is in, to be opened, then gas can flow into breathing connecting tube 6.In addition, working as
When air-flow is located by connecting pipe 2 from the breathing flow direction of connecting tube 6, it is able to achieve using the head for the pipe 2 that is located by connecting and cut-off diaphragm 5 is carried out
Support, cut-off diaphragm 5 are fitted in the head end for the pipe 2 that is located by connecting and close connecting tube venthole 12, close so that air flow switch is in
Closed state.
The direction of the vertex of a cone is directed toward at the cone bottom of the taper and the direction breathing direction of connecting tube 6 of pipe 2 that is located by connecting is consistent,
So that cut-off diaphragm 5 can be pushed open into the gas being located by connecting in pipe 2, meets air-flow and exhaled by the entrance of pipe 2 that is located by connecting
It inhales in connecting tube 6.And the gas in 2 direction of pipe that is located by connecting is directed toward along breathing connecting tube 6, in flowing, multiwaferred switch can be made
Diaphragm 5 is close to cone bottom direction, and cut-off diaphragm 5 is attached to the head for the pipe 2 that is located by connecting, between cut-off diaphragm 5 with the pipe 2 that is located by connecting
Head fits formed closed state block breathing connecting tube 6 in gas flow be located by connecting in pipe 2.
As shown in Figure 4 and Figure 5, be located by connecting the first positioning step of pipe 7 and positioning are set on the pipe 2 that is located by connecting
The breathing being adapted to the second positioning step of pipe 8 that is located by connecting is arranged in breathing connecting tube 6 and connects for the second positioning step of connecting tube 8
Adapter tube positioning step 9, and sealing positioning step 10 is also set up in breathing connecting tube 6；
When the head end of pipe 2 of being located by connecting protrudes into breathing connecting tube 6, breathes the tail end of connecting tube 6 and be located by connecting pipe first
The alignment positioning of positioning step 7, and breathe connecting tube positioning step 9 and be directed at positioning with the second positioning step of pipe 8 that is located by connecting；Air-flow
In the open state, air flow switch and sealing positioning step 10 cooperate switch, can stop one-way exhaust pipe 4 and breathing connecting tube
Connected state between 6.
In the utility model embodiment, match in order to facilitate realizing to be located by connecting pipe 2 and breathe the connection between connecting tube 6
It closes, be located by connecting the first positioning step of pipe 7 and the second positioning step of pipe that is located by connecting is set on the outer wall for the pipe 2 that is located by connecting
8, the second positioning step of pipe 8 that is located by connecting, which is located at, to be located by connecting between the first positioning step of pipe 7 and cut-off diaphragm 5, is located by connecting
For the first positioning step of pipe 7 with the tail end of positioned adjacent connecting tube 2, the outer diameter for the first positioning step of pipe 7 that is located by connecting is greater than positioning
The outer diameter of the first positioning step of connecting tube 8.
The setting breathing connecting tube positioning step 9 in breathing connecting tube 6, when the head end for the pipe 2 that is located by connecting is embedded in breathing
When in connecting tube 6, the tail end of breathing connecting tube 6 can be aligned with the first positioning step of pipe 7 that is located by connecting, and breathe the interior of connecting tube 6
Diameter outer diameter adaptation corresponding with the pipe 2 that is located by connecting, breathing connecting tube positioning step 9 can be with the second positioning step of pipe 8 that is located by connecting
Alignment.
After the pipe 2 that is located by connecting is positioned by above-mentioned positioning step to group cooperation with breathing connecting tube 6, in normal ventilation feelings
Under condition, air-tightness requirement can guarantee.When between cut-off diaphragm 5 in the open state, utilize cut-off diaphragm 5 and sealing positioning table
The contact of rank 10 can block one-way exhaust pipe 4 and breathe the connected state between connecting tube 6, i.e. cut-off diaphragm 5 and sealing positions
After step 10 contacts, air-flow can not be discharged by one-way exhaust pipe 4, can only carry out gas discharge by breathing connecting tube 6.
In addition, the outer wall in the breathing connecting tube 6 is concavely provided with locating slot 11, the locating slot 11 is located at breathing connection
Between pipe positioning step 9 and sealing positioning step 10.In the utility model embodiment, breathing connection can be mitigated using locating slot 11
The weight of pipe 6, moreover it is possible to the effects of realizing positioning, holding.
In the utility model embodiment, the gas of discharge can be carried out to sterilize only by being additionally provided in the one-way exhaust pipe 4
The gas bactericidal purifying mechanism of change.Wherein, gas bactericidal purifying mechanism can carry out gas using filter paper, filter membrane etc.
The form of purification, specifically can according to need and is selected, and when gas needs to be discharged by one-way exhaust pipe 4, need first to pass through
It crosses gas bactericidal purifying mechanism and carries out bactericidal purifying, after the gas discharge after bactericidal purifying, to surrounding when being avoided that breathing
The pollution of gas.Certainly, in the specific implementation, the gas that one-way exhaust pipe 4 is discharged can also be sent into scavenging solution, that is, passed through
It is discharged after scavenging solution purification, scavenging solution can use physiological saline, and the forms such as pure water specifically can according to need and be selected
