Specific embodiment
In conjunction with referring to shown in Fig. 1, Fig. 2, embodiment according to the present utility model provides a kind of blast switch, including shell
10, the diaphragm 1 that its inner cavity is divided into the first cavity and the second cavity is provided in the shell 10, goes back structure on the shell 10
Positive pressure mouth 11, negative pressure mouth 12 are made, the positive pressure mouth 11 penetrates through exterior line and the first cavity, and the negative pressure mouth 12 then penetrates through outer
Portion's pipeline and the second cavity are additionally provided with spring 2, elastic arm 14, signal exit 16,1 direction of diaphragm inside the shell 10
2 side of spring is configured with boss 3, and the boss 3 has the shrinkage pool 4 extended towards 1 side of diaphragm, the spring 2
First end in the shrinkage pool 4, the elastic arm 14 can be followed when 1 position of diaphragm changes occurs position
It changes, and then is able to drive connected reed 13 and occurs different bendings, the reed 13, and/or, the elastic arm 14
One end be equipped with contact 15, the contact 15 is selective under the action of the elastic arm 14 and reed 13 to draw with the signal
The different termination contacts at end 16, and then corresponding signal can be transmitted out to outside, to realize the function of blast switch.Specifically
Ground, after the blast switch and external wind path pipeline assemble, when between the first cavity and the second cavity there are when pressure, diaphragm
1 will move under the action of wind pressure pressure difference towards 2 side of spring, will also compress the spring 2, and the contact 15 will
One terminal of separating signal exit 16 under the action of the elastic arm 14 and reed 13 and with another termination contact.The skill
By the connection that the boss Innovation of Connection of spring in the prior art and diaphragm is using the shrinkage pool 4 in art scheme, make the spring 2
Firmly in the shrinkage pool 4, the connection reliability of spring 2 Yu diaphragm 1 is greatly improved, spring 2 and diaphragm 1 are prevented
The generation of break-off, it is strong to improve blast switch working performance.
Further, internal screw thread is configured on 4 hole wall of shrinkage pool, the first end of the spring 2 can be with the interior spiral shell
