Detailed Description
The following are preferred embodiments of the present application, and it should be noted that modifications and variations can be made by those skilled in the art without departing from the principle of the present application, and these modifications and variations are also considered as the protection scope of the present application.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a fire extinguisher starting apparatus according to an embodiment of the present application. Fig. 2 is a top view of fig. 1. Fig. 3 is a schematic cross-sectional view taken along A-A in fig. 2. The embodiment provides a fire extinguisher starting device 1, specifically, the fire extinguisher starting device 1 includes a housing 10, a feeding hole 11 and a discharging hole 12 are provided on the housing 10, and a receiving space 13 communicating the feeding hole 11 and the discharging hole 12 is provided in the housing 10. A temperature sensing element 20 disposed in the accommodating space 13, wherein one end of the temperature sensing element 20 abuts against the side wall 14 of the housing 10 to form the accommodating space 13, so as to isolate the feeding hole 11 from the discharging hole 12; when the temperature of the temperature sensing member 20 reaches a first preset temperature, at least part of the temperature sensing member 20 is broken, so that the feeding hole 11 is communicated with the discharging hole 12.
The fire extinguisher starting device 1 provided by the application can be applied to fire extinguishers 2 with various structures, so as to control the fire extinguishing time of the fire extinguishers 2. The fire extinguisher starting apparatus 1 provided in this embodiment mainly includes a housing 10 and a temperature sensing member 20. Wherein the housing 10 is a casing of the fire extinguisher starting device 1 for housing other components of the fire extinguisher starting device 1 and the casing also serves to protect the other components. The shell 10 is provided with a feeding hole 11 and a discharging hole 12, the feeding hole 11 is used for enabling the fire extinguishing agent 4 to enter, and the discharging hole 12 is used for spraying the fire extinguishing agent 4. And the housing 10 is also provided with an accommodating space 13 for communicating the feeding hole 11 and the discharging hole 12. The fire extinguishing agent 4 thus enters from the inlet opening 11 and finally is ejected from the outlet opening 12 through the receiving space 13. Optionally, the fire extinguishing agent 4 may be made of a material including, but not limited to, heptafluoropropane or perfluorohexanone.
Next, the temperature sensing element 20 may be disposed in the accommodating space 13, and one end of the temperature sensing element 20 abuts against the sidewall 14, thereby blocking the feeding hole 11 and the discharging hole 12. So that the fire extinguishing agent 4 in the fire extinguishing bottle 3 is not sprayed out from the discharge hole 12 when no fire is normally occurring. In addition, the temperature sensing element 20 has special performance, namely, when the temperature of the temperature sensing element 20 reaches the first preset temperature, at least part of the temperature sensing element 20 can be automatically damaged, so that the temperature sensing element 20 is broken. Therefore, in the event of a fire, the ambient temperature in the vicinity of the fire extinguisher 2 increases continuously, thereby increasing the temperature of the temperature sensing member 20. When the temperature of the temperature sensing member 20 reaches the first preset temperature, the temperature sensing member 20 will rupture, and at this time, one end of the temperature sensing member 20 will not continuously abut against the side wall 14 of the housing 10 surrounding the housing space 13, so that the feeding hole 11 is communicated with the discharging hole 12, and the fire extinguishing agent 4 in the fire extinguisher 2 is further sprayed from the feeding hole 11 through the housing space 13 and finally from the discharging hole 12, so as to automatically extinguish the fire in the place where the fire occurs. Therefore, the fire extinguisher starting device 1 provided by the application can realize automatic fire extinguishing without manual operation of the fire extinguisher 2 by a user, improves the timeliness and accuracy of fire extinguishing, and reduces the fire extinguishing difficulty and the fire extinguishing cost.
Referring to fig. 4 together, fig. 4 is a schematic cross-sectional view of a fire extinguisher activation device according to another embodiment of the present application. In the present embodiment, the temperature sensing element 20 includes a temperature sensing portion 21 and a blocking portion 22 that are connected, wherein one end of the blocking portion 22 abuts against the housing 10 to form the side wall 14 of the accommodating space 13, and one end of the temperature sensing portion 21 abuts against the housing 10 to form the top wall 15 of the accommodating space 13; the pressure in the feeding hole 11 is greater than the pressure outside the discharging hole 12, when the temperature of the temperature sensing part 21 reaches the first preset temperature, the temperature sensing part 21 is broken, and the blocking part 22 moves under the driving of the pressure difference, so that the feeding hole 11 is communicated with the discharging hole 12.
In the present embodiment, the temperature sensing element 20 is not a single integral structure, but is composed of a plurality of structures including the temperature sensing portion 21 and the blocking portion 22. Wherein the blocking part 22 is used for blocking the feeding hole 11 from the discharging hole 12, and the temperature sensing part 21 is used for breaking the temperature sensing part 21 when the temperature reaches the first preset temperature. It is also understood that the two functions of the temperature sensing element 20 are respectively realized by the temperature sensing portion 21 and the blocking portion 22. Specifically, one end of the blocking portion 22 abuts against the side wall 14 of the housing 10 to form the accommodating space 13, the opposite end of the blocking portion 22 is connected to the opposite end of the temperature sensing portion 21, and one end of the temperature sensing portion 21 abuts against the housing 10 to form the top wall 15 of the accommodating space 13. Alternatively, the temperature sensing portion 21 includes, but is not limited to, a glass bulb. Optionally, the barrier 22 includes, but is not limited to, a stopper.
In the field of fire extinguishers 2, in order to better eject the extinguishing agent 4 from the extinguishing bottle 3, the pressure in the extinguishing bottle 3 will normally be greater than the pressure of the outside world. Thus, when the temperature sensing portion 21 breaks, the opposite end of the blocking portion 22 cannot be connected to the opposite end of the temperature sensing portion 21, that is, the opposite end of the blocking portion 22 cannot be connected to the top wall 15, thereby achieving fixation. Because the pressure in the feeding hole 11 is greater than the pressure outside the discharging hole 12, the blocking portion 22 can move away from the feeding hole 11 under the driving of the pressure difference (the difference between the pressure in the feeding hole 11 and the pressure outside the discharging hole 12), and at this time, one end of the blocking portion 22 will not form the side wall 14 of the accommodating space 13 when abutting against the housing 10, i.e. the blocking portion 22 will not block the feeding hole 11, and finally the feeding hole 11, the accommodating space 13 and the discharging hole 12 are mutually communicated, so as to provide a spraying channel for the fire extinguishing agent 4.
Referring to fig. 5-6 together, fig. 5 is a schematic cross-sectional view of a fire extinguisher activation device according to another embodiment of the present application. Fig. 6 is a schematic view of the blocking portion in an embodiment of the application when the opposite end abuts against the top wall. In this embodiment, the discharging hole 12 may expose a portion of the blocking portion 22, and a vertical distance between one end of the blocking portion 22 and the discharging hole 12 is smaller than a vertical distance between the opposite end of the blocking portion 22 and the top wall 15.
In some embodiments, the feed aperture 11 may be blocked with a blocking portion 22, thereby blocking the feed aperture 11 from the discharge aperture 12. In the present embodiment, the blocking portion 22 may be used to block the feed hole 11 and the discharge hole 12 at the same time, thereby further improving the blocking effect.
In addition, the vertical distance between one end of the blocking portion 22 and the discharge hole 12 (as shown in the direction D1 in fig. 5) may be smaller than the vertical distance between the opposite end of the blocking portion 22 and the top wall 15 (as shown in the direction D2 in fig. 5). In this way, when the blocking portion 22 moves in a direction away from the feed hole 11, that is, the opposite end of the blocking portion 22 moves in a direction away from the feed hole 11, since the vertical distance between one end of the blocking portion 22 and the discharge hole 12 is smaller than the vertical distance between the opposite end of the blocking portion 22 and the top wall 15. Thus, when the opposite end of the blocking portion 22 abuts the top wall 15, one end of the blocking portion 22 may be completely separated from the tap hole 12, and it is understood that the blocking portion 22 is not completely visible in the tap hole 12. This can further increase the number of the fire extinguishing agent 4 to be sprayed out and improve the fire extinguishing effect.
Referring to fig. 7 together, fig. 7 is a schematic cross-sectional view of a fire extinguisher activation device according to another embodiment of the present application. In this embodiment, after the blocking portion 22 moves under the driving of the pressure difference, the periphery of the blocking portion 22 may also abut against the side wall 14 to partition the accommodating space 13 into a first sub-accommodating space 131 and a second sub-accommodating space 132; the broken temperature sensing part 21 is disposed in the first sub-accommodating space 131, and the feeding hole 11 and the discharging hole 12 are communicated with the second sub-accommodating space 132.
In this embodiment, after the blocking portion 22 moves under the driving of the pressure difference, the periphery of the blocking portion 22 may be continuously abutted against the side wall 14, so that the blocking portion 22 may be continuously blocked from the empty space, and the accommodating space 13 may be partitioned into a first sub-accommodating space 131 and a second sub-accommodating space 132. The broken temperature sensing part 21 is arranged in the first sub-accommodating space 131, and the feeding hole 11 and the discharging hole 12 are communicated with the second sub-accommodating space 132. This allows the broken temperature sensing portion 21 to remain in the first sub-housing space 131, thereby preventing the broken temperature sensing portion 21 from entering the feed hole 11 from the second sub-housing space 132 to affect the discharge of the fire extinguishing agent 4. The broken temperature sensing part 21 is prevented from being discharged from the second sub-receiving space 132 into the discharge hole 12, thereby affecting the equipment around the fire extinguisher 2.
Referring to fig. 8, fig. 8 is a schematic cross-sectional view of a fire extinguisher activation device according to another embodiment of the present application. In this embodiment, the opening size of the accommodating space 13 near the feeding hole 11 is smaller than the opening size of the accommodating space 13 far from the feeding hole 11.
In this embodiment, the opening size of the accommodating space 13 near the feeding hole 11 may be smaller than the opening size of the accommodating space 13 far from the feeding hole 11. This can facilitate the blocking portion 22 and the side wall 14 abutting each other to block the feed hole 11 and the discharge hole 12, and can also facilitate the blocking portion 22 to move in a direction away from the feed hole 11. The blocking effect and the moving performance of the blocking portion 22 are improved.
Referring to fig. 8 again, in the present embodiment, the top wall 15 is movably connected to the side wall 14, and the top wall 15 may move toward the direction approaching the discharge hole 12, or the top wall 15 may move toward the direction separating from the discharge hole 12.
In this embodiment, the top wall 15 may be movably connected to the side wall 14, and it may be understood that the top wall 15 may be moved toward the direction approaching the discharge hole 12, or the top wall 15 may be moved toward the direction separating from the discharge hole 12 (as shown in the direction D3 in fig. 8). Thus, not only the temperature sensing piece 20 can be conveniently installed and disassembled, but also the vertical distance between one end of the blocking part 22 and the discharging hole 12 and the vertical distance between the opposite end of the blocking part 22 and the top wall 15 can be adjusted by utilizing the movement of the top wall 15.
Referring to fig. 9 together, fig. 9 is a schematic cross-sectional view of a fire extinguisher activation device according to another embodiment of the present application. In this embodiment, the fire extinguisher starting device 1 further includes a starting member 30 connected to the housing 10, the housing 10 is provided with a first through hole 16 communicating with the accommodating space 13, part of the starting member 30 is disposed in the first through hole 16, and one end of the starting member 30 is close to the temperature sensing member 20; the activating member 30 is configured to apply a force to the temperature sensing member 20 when the ambient temperature reaches the second preset temperature, so as to rupture the temperature sensing member 20.

When the activating member 30 is used for making the ambient temperature reach the second preset temperature, the activating member 30 applies a force to the temperature sensing member 20, that is, one end of the activating member 30 may strike the temperature sensing member 20, so that the temperature sensing member 20 is broken by an external force, and finally the fire extinguishing agent 4 is sprayed.
In the present embodiment, by additionally providing the actuator 30, the temperature sensing element 20 is ruptured by the actuator 30, and the rupturing mode of the temperature sensing element 20 can be increased, so that the temperature sensing element 20 is ruptured in various modes. For example, the user may manually activate the actuator 30 for manual activation purposes. The actuator 30 may also be coupled to a processor to enable a user to remotely actuate the actuator 30 for remote actuation purposes.
