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 is disclosed in at least one embodiment of the present application, the activation device 100 is used to activate a non-stored pressure fire extinguisher 200, and the non-stored pressure fire extinguisher 200 includes a gas generating agent 231. Referring to fig. 2, the starting device 100 includes a connecting member 110, a medicament housing 120, a heat conducting member 130, a first ignition medicament 143, a first heat-sensitive wire 141, and a second heat-sensitive wire 142.
The connecting member 110 of the actuating device 100 may be connected to a fire extinguishing housing 210 of the fire extinguisher 200, which has a connecting chamber 111.
The medicament housing 120 is coupled to the connecting member 110. Specifically, the medicament housing 120 is coupled to an end of the connector 110 distal from the fire suppression housing 210. More specifically, the medicine housing 120 has a medicine chamber 121 and a heat conduction port 125 penetrating the medicine chamber 121 and the connection chamber 111.
Wherein the first priming medicament 143 is filled in the medicament cavity 121 of the medicament housing 120; the heat conductive member 130 of the activation device 100 is sealed to the heat conductive port 125 to configure the connection chamber 111 and the medicine chamber 121 to be independent from each other. In particular, in some embodiments, the thermal conductive member 130 may be a thermally conductive spacer. Alternatively, the heat-conducting member 130 may be integrally formed with the connecting member 110, or may be assembled.
Further, the medicine housing 120 further has a first line passing hole 123 communicating the inside and the outside of the medicine chamber 121. In particular, in the present embodiment, one end of the first thermo-sensitive wire 141 is reserved outside the medicine housing 120, and the other end thereof passes through the first wire passing hole 123 of the medicine housing 120 to be connected to the first priming medicine 143.
Further, a second thermo-sensitive wire 142 is disposed in the connection chamber 111, and has one end connected to the heat conductive member 130 and the other end connected to the gas generating agent 231.
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 first thermosensitive wire 141 is heated and burned to ignite the first ignition chemical 143 filled in the chemical chamber 121. The first ignition agent 143 burns to generate heat and transfers the heat to the heat conductive member 130, and the second heat sensitive wire 142 connected to the heat conductive member 130 thermally burns to activate the gas generating agent 231. After the gas generating agent 231 is activated, a large amount of gas is rapidly generated, so that the fire extinguishing agent 233 is pushed out of the fire extinguisher 200 to extinguish the fire. Thus, after the gas generating agent 231 is activated, since the heat conducting member 130 is sealed in the heat conducting port 125, the gas generated by the gas generating agent 231 cannot be discharged from the first line passing hole 123 communicated with the heat conducting port 125, and all the generated gas is used for pushing the fire extinguishing agent 233 to be sprayed out of the fire extinguisher 200. Thereby, the strength of the fire extinguisher 200 to spray the fire extinguishing agent 233 is ensured, and the fire extinguishing effect is improved.
Further, to prevent the second heat wire 142 from failing to ignite the gas generant 231, in some embodiments, the activation device 100 further includes a second ignition agent disposed within the connecting lumen 111.
In practice, the second thermal wire 142 is heated to burn and then ignite the second ignition agent, and the second ignition agent is burned to generate a large amount of heat sufficient to ignite the gas generating agent 231. In this manner, the start gas generant 231 can be effectively prevented from being deteriorated.
To prevent the heat-conducting member 130 from being displaced during start-up to cause gas leakage from the gas generant 231, in some embodiments, the start-up apparatus 100 further includes a securing member 150. The fixing member 150 is supported on the connecting member 110 and cooperates with the medicament housing 120 to limit the heat conducting member 130 at the heat conducting port 125 of the medicament housing 120.
Further, as shown in fig. 2, the fixing member 150 is provided with a second wire passing hole 152 communicating the heat conducting member 130 and the connecting cavity 111 of the connecting member 110. The second wire through hole 152 is provided to facilitate the arrangement of the second heat sensitive wire 142.
In particular, in the embodiment of the present application, the fixing member 150 may be a capillary tube having one end abutting against the connecting member 110 and the other end supporting the heat conducting member 130 on the heat conducting port 125 of the medicament housing 120. Thus, the position of the heat-conducting member 130 can be stabilized, and the ejection pressure can be prevented from being insufficient due to the offset of the heat-conducting member 130.
It should be appreciated that the first ignition agent 143 may generate a large amount of high temperature gas, even open fire, while burning. If the above products are sprayed from the first wire through hole 123 to the outside of the apparatus during the starting process, secondary damage may be caused.
Accordingly, in some embodiments, the starting apparatus 100 further comprises a flame trap housing 160. Referring to fig. 2, the flame trap housing 160 is coupled to the connecting member 110 and spaced apart from the outer layer of the medicament housing 120, and a flame trap channel 161 is formed at a space between the flame trap housing 160 and the medicament housing 120.
Further, a third line through hole 163 is formed in the flame trap housing 160, one end of the first thermal sensitive line 141 is reserved outside the flame trap housing 160, and the other end of the first thermal sensitive line passes through the third line through hole 163, the flame trap channel 161 and the first line through hole 123 in sequence to be connected to the first ignition chemical 143.
In practical applications, the high-temperature gas and the open flame generated by the combustion of the first ignition agent 143 gradually decrease and disappear during the process of passing through the flame-extinguishing passage 161. Thus, it can be ensured that the flame is not discharged to the outside of the device, and it is ensured that the first ignition agent 143 does not cause damage to the environment outside the device.
Further, in order to enhance the effect of the flame-extinguishing passage 161 on the attenuation of the high-temperature gas and the open flame generated by the combustion of the first ignition chemical 143, in some embodiments, the first wire through hole 123 is disposed at an end of the chemical housing 120 close to the heat conducting member 130, and the third wire through hole 163 is disposed at an end of the flame-extinguishing housing 160 far from the heat conducting member 130. In this way, the length of the flame trap path 161 is effectively extended.
As the same concept of the present application, there is also provided a fire extinguisher 200. Referring to fig. 3, the fire extinguisher 200 includes a fire extinguishing housing 210, a gas generating agent 231, a fire extinguishing agent 233, an ejector 250, and an actuating device 100.
The fire extinguishing housing 210 has a gas generating chamber 211 and a fire extinguishing chamber 213 communicating with each other. The gas generating agent 231 is filled in the gas generating cavity 211, and the fire extinguishing agent 233 is filled in the fire extinguishing cavity 213. Further, the fire extinguishing case 210 further includes a trigger port 215 and an ejection port 217 communicating the gas generation chamber 211 and the fire extinguishing chamber 213, respectively.
And an ejector 250 movably disposed between the gas generation chamber 211 and the fire extinguishing chamber 213. In particular, in the embodiment of the present application, the pushing member 250 may be a piston movably disposed between the gas generating chamber 211 and the fire extinguishing chamber 213. After the starting device 100 starts the gas generating agent 231 to generate gas, the piston can be pushed to move, so that the fire extinguishing agent 233 is sprayed out of the spraying port 217 to extinguish fire.
In some embodiments, the activation device 100 includes a connector 110, a medicament housing 120, a thermally conductive member 130, a first priming medicament 143, a first heat-sensitive wire 141, and a second heat-sensitive wire 142.
The connector 110 is coupled to the fire extinguishing housing 210. Specifically, the connecting member 110 has a connecting cavity 111, and the connecting cavity 111 communicates with the trigger port 215.
The medicament housing 120 is coupled to the connecting member 110. Specifically, the medicament housing 120 is coupled to an end of the connector 110 distal from the fire suppression housing 210. More specifically, the medicine housing 120 has a medicine chamber 121 and a heat conduction port 125 penetrating the medicine chamber 121 and the connection chamber 111.
Wherein the first priming medicament 143 is filled in the medicament cavity 121 of the medicament housing 120; the heat conductive member 130 of the priming device 100 is sealed to the heat conductive port 125 to configure the connecting chamber 111 and the medicament chamber 121 to be independent of each other. In particular, in some embodiments, the thermal conductive member 130 may be a thermally conductive spacer. Alternatively, the heat-conducting member 130 may be integrally formed with the connecting member 110, or may be assembled.
Further, the medicine housing 120 further has a first line passing hole 123 communicating the inside and the outside of the medicine chamber 121. In particular, in the present embodiment, one end of the first thermo-sensitive wire 141 is reserved outside the medicine housing 120, and the other end thereof passes through the first wire passing hole 123 of the medicine housing 120 to be connected to the first priming medicine 143.
Further, a second thermo-sensitive wire 142 is disposed in the connection chamber 111, and has one end connected to the heat conductive member 130 and the other end connected to the gas generating agent 231.
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 first thermal wire 141 is heated and burned to ignite the first ignition chemical 143 filled in the chemical cavity 121. The first ignition agent 143 burns to generate heat and transfers the heat to the heat conductive member 130, and the second heat sensitive wire 142 connected to the heat conductive member 130 thermally burns to activate the gas generating agent 231. After the gas generating agent 231 is activated, a large amount of gas is rapidly generated, so that the fire extinguishing agent 233 is pushed out of the fire extinguisher 200 to extinguish the fire. Thus, after the gas generating agent 231 is activated, since the heat conducting member 130 is sealed in the heat conducting port 125, the gas generated by the gas generating agent 231 cannot be discharged from the first line passing hole 123 communicated with the heat conducting port 125, and all the generated gas is used for pushing the fire extinguishing agent 233 to be sprayed out of the fire extinguisher 200. Thereby, the strength of the fire extinguisher 200 to spray the fire extinguishing agent 233 is ensured, and the fire extinguishing effect is improved.
Further, to prevent the second heat wire 142 from failing to ignite the gas generant 231, in some embodiments, the activation device 100 further includes a second ignition agent disposed within the connecting lumen 111.
In practice, the second thermal wire 142 is heated to burn and then ignite the second ignition agent, and the second ignition agent is burned to generate a large amount of heat sufficient to ignite the gas generating agent 231. In this manner, the start gas generant 231 can be effectively prevented from being deteriorated.
To prevent the heat-conducting member 130 from being displaced during start-up to cause gas leakage from the gas generant 231, in some embodiments, the start-up apparatus 100 further includes a securing member 150. The fixing member 150 is supported on the connecting member 110 and cooperates with the medicament housing 120 to limit the heat conducting member 130 at the heat conducting port 125 of the medicament housing 120.
Further, as shown in fig. 2, the fixing member 150 is provided with a second wire passing hole 152 communicating the heat conducting member 130 and the connecting cavity 111 of the connecting member 110. The second wire through hole 152 is provided to facilitate the arrangement of the second heat sensitive wire 142.
In particular, in the embodiment of the present application, the fixing member 150 may be a capillary tube having one end abutting against the connecting member 110 and the other end supporting the heat conduction member 130 on the heat conduction port 125 of the medicament housing 120. Thus, the position of the heat-conducting member 130 can be stabilized, and the ejection pressure can be prevented from being insufficient due to the offset of the heat-conducting member 130.
It should be appreciated that the first ignition agent 143 may generate a large amount of high temperature gas, even open fire, while burning. If the above products are sprayed from the first wire through hole 123 to the outside of the apparatus during the starting process, secondary damage may be caused.
Accordingly, in some embodiments, the starting apparatus 100 further comprises a flame trap housing 160. Referring to fig. 2, the flame trap housing 160 is coupled to the connecting member 110 and spaced apart from the outer layer of the medicament housing 120, and a flame trap channel 161 is formed at a space between the flame trap housing 160 and the medicament housing 120.
Further, a third line passing hole 163 is formed on the flame trap housing 160, one end of the first thermosensitive line 141 is reserved outside the flame trap housing 160, and the other end thereof sequentially passes through the third line passing hole 163, the flame trapping passage 161 and the first line passing hole 123 to be connected to the first ignition chemical 143.
In practical applications, the high-temperature gas and the open flame generated by the combustion of the first pilot agent 143 gradually decrease and disappear during the process of passing through the flame-extinguishing passage 161. Thus, it can be ensured that the flame is not discharged to the outside of the device, and it is ensured that the first ignition agent 143 does not cause damage to the environment outside the device.
Further, in order to enhance the effect of the flame-extinguishing passage 161 on the reduction of the high-temperature gas and the open flame generated by the combustion of the first ignition chemical 143, in some embodiments, the first wire hole 123 is disposed at an end of the chemical housing 120 close to the heat conductive member 130, and the third wire hole 163 is disposed at an end of the flame-extinguishing housing 160 away from the heat conductive member 130. Thus, the length of the flame trap channel 161 is effectively extended.
All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure 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.
