The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
Embodiment one
Referring to figure 1, figure 2 and figure 3, valve includes valve body 1, valve block 2 and bindiny mechanism 3, and valve body 1 includes exhaust pipe 12, setting
In 12 tail end of exhaust pipe and outwardly extending decoration panel 13 and the ring baffle that 12 head end of exhaust pipe is arranged in and extends internally
11, ring baffle 11 is equipped with exhaust outlet 111, is provided with valve seat 6 on the inner wall of exhaust pipe 12,3 lower end of bindiny mechanism is movable
Ground is arranged on valve seat 6, and 3 upper end of bindiny mechanism is movably disposed on valve block 1, and valve block 2 is equipped with every cigarette part 21, connects machine
When structure 3 drives valve block 2 to close exhaust outlet 111, offset every the inner wall of the outer wall and ring baffle 11 of cigarette part 21.In the utility model
Other embodiments in, valve seat is provided on the inner wall of decoration panel, bindiny mechanism lower end is movably disposed on valve seat;Or
Person is that valve seat (part valve seat and the fixed company of the inner wall of decoration panel are provided on the inner wall of decoration panel and the inner wall of exhaust pipe
Connect, with exhaust pipe inner wall is fixedly connected remainder valve seat), bindiny mechanism lower end is movably disposed on valve seat.
It should be understood that it is " when every cigarette part 21 that valve block 2, which closes the meaning expressed by exhaust outlet 111, in the present embodiment
When the inner wall of outer wall and ring baffle 11 offsets, smoke exhaust (the smoke evacuation pipe sleeve on smoke exhaust is on the outer wall of exhaust pipe 12)
The gas of discharge can not be entered in exhaust duct by exhaust outlet 111, also, the gas in exhaust duct can not also pass through exhaust outlet
111 move at smoke exhaust ".
In the present embodiment, valve body 1 is by sequentially forming decoration panel 13, exhaust pipe 12 and ring baffle after metal sheet stretch
11, decoration panel 13 is equipped with step 131, and step 131 includes the step surface connecting with exhaust pipe 12 and faced away from by step
The annular sidewall that 12 direction of exhaust pipe extends, valve further include the flexible gaskets 5 being arranged on step surface, are in ring in the present embodiment
The flexible gaskets 5 of shape are pasted on step surface, also, the flexible gaskets 5 can be made of rubber or refractory cotton, flexible gaskets 5
Height be H1, the height of annular sidewall is H2, H1 > H2.From figure 3, it can be seen that flexible gaskets 5 extend to as H1 > H2
It outside step 131, is designed in this way, when valve is mounted on the side wall of exhaust duct, flexible deformation occurs for flexible gaskets 5, is mentioned with realizing
High threshold every smoke performance.In the other embodiments of the utility model, flexible gaskets are fixedly connected with decoration panel by rivet,
Also, when flexible gaskets are fixedly connected with decoration panel by rivet, step surface and annular sidewall respectively with flexible gaskets mistake
It is full of cooperation.

The modes such as be spirally connected are arranged on exhaust pipe.
Referring to Fig. 3, the present embodiment every cigarette part 21 be every cigarette ring, every on the outer wall that valve block 2 is arranged in cigarette ring, every cigarette part
When 21 outer wall and the inner wall of ring baffle 11 offset and close exhaust outlet 111, valve block 2 offsets with ring baffle 11, specific:
From figure 3, it can be seen that when the inner wall of outer wall and ring baffle 11 every cigarette part 21 offsets and closes exhaust outlet 111, valve block 2
Peripheral edge offsets along the inner wall with ring baffle 11.Certainly, the mode more than one that valve block and ring baffle offset, for example,
When the outer wall of cigarette part and the inner wall of ring baffle offset and close exhaust outlet, the inner wall phase of the outer wall and ring baffle of valve block
It supports.It is designed in this way, exhaust outlet 111 realizes Duoble cigarette.
When being when cigarette ring every cigarette part 21, the weight of valve can suitably mitigate and the manufacturing cost of valve can suitably drop
It is low, in the case where not considering valve weight, manufacturing cost, can be every cigarette part 21 every cigarette pad, it is rounded every cigarette pad.
Preferably, it is made of rubber every cigarette ring hot-melt adhesive paste on 2 outer wall of valve block made of metal.It is designed in this way,
Increase the bonding strength between cigarette ring and valve block 2.
In the present embodiment, valve further includes plectrum, temperature-sensing element and the first torsional spring, and plectrum and valve body 1 are rotatablely connected, temperature-sensitive member
Part is fixed on valve body 1, and on the first torsional spring a torque arm is arranged on valve body 1, another torque arm setting on the first torsional spring
So that plectrum squeezes temperature-sensing element on plectrum.Temperature-sensing element is (after temperature-sensing element can be two pieces of sheet metals by solder welding
It is linked together, temperature-sensing element is also possible to memory metal) it can be separated by fusing and deformed movement realization with plectrum,
After temperature-sensing element is separated with plectrum, the first torsional spring drives plectrum to rotate, to realize that plectrum is press-connected mechanism 3 and by connection machine
Structure 3 drives valve block 2 to close exhaust outlet 111.
Referring to Fig. 3, the valve of the present embodiment further includes the second torsional spring 4, and the second torsional spring 4 connects the bindiny mechanism 3 and valve body 1
And rotated for drive connection mechanism 3 relative to the valve body 1, bindiny mechanism 3 is equipped with accommodating cavity 311, the spring coil of the second torsional spring 4
Main center's axle position is in accommodating cavity 311.
Referring to Fig. 3, bindiny mechanism 3 include connecting rod 31, shaft 32, the first bolt 33, the first nut 34, the second bolt 35,
Second nut 36, the first helical spring and the second helical spring, 31 lower end of connecting rod are turned by the inner wall of shaft 32 and exhaust pipe 12
Dynamic connection, the first bolt 33 connect after sequentially passing through the upper end of connecting rod 31, the first helical spring and valve block 2 with the fixation of the first nut 34
It connecing, the second bolt 35 is fixedly connected after sequentially passing through the upper end of connecting rod 31, the second helical spring and valve block 2 with the second nut 36,
The junction of connecting rod 31 and the first bolt 33 is the first connecting portion of connecting rod 31, and the junction of connecting rod 31 and the second bolt 35 is company
The second connecting portion of bar 31.Be designed in this way, can multi-angle movement valve block 2 will by every cigarette part 21 close exhaust outlet 111, two
Helical spring may insure that valve works normally in the case where a wherein helical spring failure.In other realities of the utility model
It applies in example, bindiny mechanism includes connecting rod, three screws and three helical springs, and with exhaust pipe the inner wall rotation of connecting rod lower end connects
It connects, each screw is fixedly connected after sequentially passing through valve block and a helical spring with small end.
Preferably, first connecting portion is arranged on the eccentric position of valve block 2 and/or valve block 2 is arranged in second connecting portion
On eccentric position.When first connecting portion and second connecting portion are arranged on 2 different height position of valve block, valve block 2 is in vertical side
Upward motion range will suitably be reduced;When first connecting portion and second connecting portion setting are in the different lateral positions of valve block 2
When upper, the motion range of valve block 2 in the horizontal direction will suitably be reduced.
