The starting device and the fire extinguisher according to the present application will be described with reference to the accompanying drawings.

Referring to fig. 1, an activation device 100 disclosed in at least one embodiment of the present application may be used to activate a non-stored pressure fire extinguisher 200, as shown in fig. 3, the activation device includes an activation housing 110, a medicament housing 120, a heat-producing medicament 130, and a gas generant 150.

The actuating housing 110 is coupled to the fire extinguishing housing 210 of the fire extinguisher 200, the actuating housing 110 having a gas generation chamber 111, and the chemical housing 120 being disposed in the gas generation chamber 111. Therein, the medicament housing 120 has a medicament cavity 121.

In order to facilitate the placement of the medicament housing 120 in the gas-generating chamber 111, in some embodiments, the actuating housing 110 defines at least one mounting opening 113 near the location where the medicament housing 120 is placed. The medicament housing 120 is insertable into the gas-generating chamber 111 through the mounting port 113.

In some embodiments, the medicament housing 120 is removably attached to the activation housing 110 at the mounting port 113 and seals the mounting port 113. Optionally, the medicament housing 120 is threadably connected to the activation housing 110 at the mounting port 113.

In other embodiments, the actuator housing 110 is provided with a mounting cap 115 removably coupled to the mounting port 113. In particular, in the present embodiment, the mounting cap 115 may serve to seal the medicament chamber 121 while sealing the mounting opening 113.

The calogenic medicament 130 is disposed in the medicament cavity 121 and the gas generant 150 is disposed in the gas-producing cavity 111 and is directly activated by heat conducted by the calogenic medicament 130 to the medicament housing 120 to have a tendency to expand the gas-producing cavity 111.

Further, in order to facilitate the placement of the gas generating agent 150, in some embodiments, the actuating housing 110 further defines at least one mounting opening 113 near the location where the gas generating agent 150 is disposed and a mounting cover 115 detachably connected to the mounting opening 113. Since the structure is similar to that described above, the description will not be repeated here.

In practice, the example of starting the fire extinguisher 200 will be described. When a fire occurs in the protected space, the heat-generating medicament 130 is thermally combusted to generate heat, which is transferred to the surface of the medicament housing 120, and the gas generant 150 is directly activated by the heat. The gas generating agent 150 rapidly generates a large amount of gas after being activated, thereby pushing the fire extinguishing agent 220 out of the fire extinguisher 200 to extinguish a fire. Thus, after the gas generating agent 150 is started, the gas generated by the gas generating agent 150 cannot be discharged from the gas generating chamber 111 because the gas generating chamber 111 is closed, and all the generated gas is used for pushing the fire extinguishing agent 220 to be sprayed out of the fire extinguisher 200. Thereby, the strength of the fire extinguisher 200 to spray the fire extinguishing agent 220 is ensured, and further, the fire extinguishing effect is improved.

In some embodiments, the medicament housing 120 further has a wire passage hole 123 communicating the inside and outside of the medicament chamber 121, and the activation device 100 further includes a heat sensitive wire 141. Further, one end of the heat-sensitive wire 141 is disposed outside the medicine housing 120, and the other end passes through the wire passing hole 123 to be connected to the heat-generating medicine 130 inside the medicine chamber 121 to ignite the heat-generating medicine 130.

Specifically, referring to fig. 3, one end of the heat-sensitive wire 141 is disposed outside the medicament housing 120 and outside the gas generating chamber 111 for sensing heat in the protection space therein to trigger the starting device 100; the other end is wound around the thermal agent 130 to increase the combustion rate of the thermal agent 130.

In some embodiments, the thermal agent 130 comprises a thermal agent that is thermally capable of burning and generating a large amount of heat.

Further, to prevent the gas generant 150 from failing to prime, in some embodiments, the gas generant 150 is disposed proximate the medicament housing 120. Specifically, the gas generant 150 is in direct contact with the housing surface of the medicament housing 120. Thus, after the heat-generating medicament 130 burns and heat is transferred to the medicament housing 120, the gas generant 150 can sense heat to rapidly activate and trigger the fire extinguisher 200 to spray the fire extinguishing agent 220, thereby achieving rapid fire extinguishing.

The present application also provides a fire extinguisher 200 as the same concept of the present application. Referring to fig. 1-3, the fire extinguisher 200 includes a fire extinguishing housing 210, a fire extinguishing agent 220, and an actuating device 100.

The fire extinguishing housing 210 has a fire extinguishing chamber 211, and a fire extinguishing agent 220 is filled in the fire extinguishing chamber 211. Further, the fire extinguishing housing 210 has a trigger port 213 and a discharge port 215 communicating with the fire extinguishing chamber 211. The starting device 100 is used for generating gas and leading the gas into the fire extinguishing chamber 211 from the triggering port 213 to drive the fire extinguishing agent 220 in the chamber to spray out for fire extinguishing from the spraying port 215.

In some embodiments, activation device 100 includes an activation housing 110, a medicament housing 120, a thermogenic medicament 130, and a gas generant 150.

The starting housing 110 is connected to the fire extinguishing housing 210 of the fire extinguisher 200, the medicine housing 120 is coupled to the inside of the starting housing 110 and cooperates with the starting housing 110 to form a gas generating chamber 111, and the gas generating chamber 111 is communicated with the fire extinguishing chamber 211 through the triggering port 213. The fire suppression agent 220 is disposed within the fire suppression chamber 211 and is capable of being ejected from the ejection port 215 upon activation of the gas generant 150.

In particular, in the present embodiment, to facilitate the installation of the medicament housing 120, at least one installation opening 113 is formed on the actuating housing 110 and is disposed adjacent to the medicament housing 120. When the medicament housing 120 is mounted on the priming housing 110, the medicament housing 120 is placed into the priming housing 110 from the mounting port 113 and is threadedly engaged with the priming housing 110 at the mounting port 113. Thus, the medicament housing 120 and the starting housing 110 are fixed, and a closed gas generating cavity 111 is formed.

Further, a mounting cover 115 detachably coupled to the mounting opening 113 is provided. In particular, in the present embodiment, the mounting cap 115 also serves to seal the medicament chamber 121 while sealing the mounting opening 113. Further, a wire passing hole 123 is penetratingly provided at the mounting cover 115.

The exothermic agent 130 is filled in the agent cavity 121 and the gas generating agent 150 is disposed in the gas generating cavity 111 and can be directly activated by heat conducted from the exothermic agent 130 to the agent housing 120, so as to have a tendency to expand the gas generating cavity 111. Specifically, in the present embodiment, the gas generant 150 is spaced from the medicament housing 120 within the gas generant chamber 111 and the trigger port 213 is in communication with the spacing between the medicament housing 120 and the gas generant 150.

Further, in order to facilitate the placement of the gas generating agent 150, in some embodiments, the actuating housing 110 further defines at least one mounting opening 113 disposed near the gas generating agent 150 and a mounting cover 115 detachably connected to the mounting opening 113. Since the structure is similar to that described above, a description thereof will not be repeated.

Specifically, in the practical use, the fire extinguisher 200 is started as an example for explanation. When a fire occurs in the protected space, the heat-generating medicament 130 is thermally combusted to generate heat, and the heat is transferred to the surface of the medicament shell 120, so that the gas generating agent 150 is directly started by sensing heat. The gas generating agent 150 rapidly generates a large amount of gas after being activated, thereby pushing the fire extinguishing agent 220 out of the fire extinguisher 200 to extinguish a fire. Therefore, after the gas generating agent 150 is started, because the gas generating cavity 111 is closed, the gas generated by the gas generating agent 150 cannot be discharged from the gas generating cavity 111, and all the generated gas is used for pushing the fire extinguishing agent 220 to be sprayed out of the fire extinguisher 200. Further, all the generated gas enters the fire extinguishing chamber 211 from the trigger port 213, so that the pressure in the fire extinguishing chamber 211 rises, and the pressure rise causes the fire extinguishing agent 220 to be sprayed out from the spray port 215, thereby extinguishing the fire. Thus, the force of the fire extinguisher 200 to spray the fire extinguishing agent 220 is ensured, thereby improving the fire extinguishing effect.

In some embodiments, the medicament housing 120 further has a wire through hole 123 communicating the inside and outside of the medicament chamber 121, and the activation device 100 further includes a heat sensitive wire 141. Further, one end of the heat-sensitive wire 141 is disposed outside the medicine housing 120, and the other end passes through the wire passing hole 123 to be connected to the heat-producing medicine 130 inside the medicine chamber 121 to ignite the heat-producing medicine 130.

Specifically, as shown in fig. 3, one end of the heat-sensitive wire 141 is disposed outside the medicine housing 120 and outside the gas generating chamber 111, and is used for sensing heat in a protected space where the heat-sensitive wire is located to trigger the starting device 100; the other end is wound around the thermal agent 130 to increase the combustion rate of the thermal agent 130.

In some embodiments, the thermal agent 130 comprises a thermal agent that is thermally capable of burning and generating a large amount of heat.

In some embodiments, a first diaphragm 231 and a second diaphragm 232 are also included. The first diaphragm 231 is covered on the trigger port 213 and can be damaged or separated from the trigger port 213 when the gas generation cavity 111 expands; the second diaphragm 232 is disposed so as to cover the discharge port 215, and can be broken or separated from the discharge port 215 when the fire extinguishing chamber 211 is expanded.

Specifically, the first diaphragm 231 and the second diaphragm 232 have a maximum pressure value, respectively, and when the pressure in the gas generation chamber 111 and the fire extinguishing chamber 211 rises to be greater than the maximum pressure value of the first diaphragm 231 and the second diaphragm 232, respectively, the first diaphragm 231 and the second diaphragm 232 can be broken or separated from the ejection hole 215. Thus, the strength of the fire extinguisher 200 can be further ensured.

Further, the fire extinguisher 200 further includes a first fixing piece 241 and a second fixing piece 242. The first fixing member 241 is coupled to the fire extinguishing housing 210 and cooperates with the fire extinguishing housing 210 to fix the first diaphragm 231 to the triggering opening 213; the second fixing member 242 is coupled to the fire extinguishing casing 210, and fixes the second diaphragm 232 to the discharge port 215 in cooperation with the fire extinguishing casing 210.

In the embodiment of the present application, please refer to fig. 3, in which the first fixing member 241 and the second fixing member 242 are both nut members, and each nut member has a fixing hole penetrating therethrough. The nut member is screwed into the fire extinguishing housing 210, the fixing holes communicate with the inside and the outside of the fire extinguishing chamber 211, and the first diaphragm 231 and the second diaphragm 232 are fixed in the fixing holes of the respective nut members, respectively.

Further, to prevent the gas generant 150 from failing to prime, in some embodiments, the gas generant 150 is disposed proximate the medicament housing 120. Specifically, the gas generant 150 is in direct contact with the housing surface of the medicament housing 120. Thus, after the heat-generating medicament 130 burns and heat is transferred to the medicament housing 120, the gas generant 150 can sense heat to rapidly activate and trigger the fire extinguisher 200 to spray the fire extinguishing agent 220, thereby achieving rapid fire extinguishing.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
