Detailed Description
The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
Referring to fig. 1 to 3 together, fig. 1 is a schematic structural view of a fire extinguisher actuating device according to an embodiment of the present application. Fig. 2 is a top view of fig. 1. Fig. 3 is a schematic sectional view taken along a-a direction in fig. 2. This embodiment provides a fire extinguisher starting drive 1, specifically, fire extinguisher starting drive 1 includes casing 10, charge-in hole 11 and discharge opening 12 have been seted up on casing 10, have in the casing 10 the intercommunication charge-in hole 11 with the accommodating space 13 of discharge opening 12. The temperature sensing element 20 is arranged in the accommodating space 13, and one end of the temperature sensing element 20 is abutted against the side wall 14 which is surrounded by the shell 10 and forms the accommodating space 13 so as to separate the feed hole 11 from the discharge hole 12; when the temperature of the temperature sensing element 20 reaches a first preset temperature, at least a part of the temperature sensing element 20 is broken, so that the feed hole 11 is communicated with the discharge hole 12.
The application provides a fire extinguisher starting drive 1 can be applied to among the fire extinguisher 2 of various structures to the opportunity of controlling fire extinguisher 2 to put out a fire. The fire extinguisher starting device 1 according to the present embodiment mainly includes a housing 10 and a temperature sensing member 20. Wherein the housing 10 is the housing of the fire extinguisher activation apparatus 1 for housing the other components of the fire extinguisher activation apparatus 1 and the housing also serves to protect the other components. The shell 10 is provided with a feed hole 11 and a discharge hole 12, the feed hole 11 is used for feeding the fire extinguishing agent 4, and the discharge hole 12 is used for spraying the fire extinguishing agent 4. And the housing 10 is also internally provided with an accommodating space 13 for communicating the feeding hole 11 with the discharging hole 12. The extinguishing agent 4 thus enters from the inlet opening 11, passes through the receiving space 13 and finally is sprayed out of the outlet opening 12. Alternatively, the material of the fire extinguishing agent 4 includes, but is 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 may abut against the sidewall 14, thereby blocking the feed hole 11 and the discharge hole 12. Thus, the fire extinguishing agent 4 contained in the fire extinguishing bottle 3 is not discharged from the discharge hole 12 in the normal absence of a fire. In addition, the temperature sensing element 20 has a special performance, that is, when the temperature of the temperature sensing element 20 reaches a first preset temperature, at least a part of the temperature sensing element 20 will be damaged by itself, 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 is increased, and the temperature of the temperature sensing element 20 is increased. When the temperature of the temperature sensing element 20 reaches a first preset temperature, the temperature sensing element 20 will break, and at this time, one end of the temperature sensing element 20 will not continuously abut against the side wall 14 which is enclosed by the housing 10 to form the accommodating space 13, so that the feed hole 11 is communicated with the discharge hole 12, and the fire extinguishing agent 4 in the fire extinguisher 2 is sprayed out from the feed hole 11 through the accommodating space 13 and finally from the discharge hole 12, thereby automatically extinguishing the fire in the place where the fire occurs. Consequently, fire extinguisher starting drive 1 that this application provided can realize automatic fire extinguishing, need not user manual operation fire extinguisher 2, has improved the promptness and the accuracy of putting out a fire, has reduced the degree of difficulty of putting out a fire and the cost of putting out a fire.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of a fire extinguisher actuating apparatus 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 stopper portion 22 connected to each other, one end of the stopper portion 22 abuts against the side wall 14 of the housing 10 forming the accommodating space 13, and one end of the temperature sensing portion 21 abuts against the top wall 15 of the housing 10 forming the accommodating space 13; the pressure inside the feed hole 11 is greater than the pressure outside the discharge 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 is driven by the pressure difference to move, so that the feed hole 11 is communicated with the discharge hole 12.
In the present embodiment, the temperature sensing element 20 is not an integral structure, but is formed by combining a plurality of structures including the temperature sensing unit 21 and the stopper 22. The blocking part 22 is used for blocking the feed hole 11 and the discharge 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 realized by the temperature sensing part 21 and the stopper part 22, respectively. Specifically, one end of the stopper 22 abuts against the side wall 14 of the housing 10 forming the accommodating space 13, the other end of the stopper 22 opposite to the other end of the temperature sensing unit 21 opposite to the other end of the stopper 22, and one end of the temperature sensing unit 21 abuts against the top wall 15 of the housing 10 forming the accommodating space 13. Alternatively, the temperature sensing part 21 includes, but is not limited to, a glass bulb. Optionally, the barrier 22 includes, but is not limited to, a plug.
In the field of fire extinguishers 2, in order to achieve a better ejection of the extinguishing agent 4 from the fire extinguisher bottle 3, the pressure inside the fire extinguisher bottle 3 is usually higher than the external pressure. When the temperature sensing part 21 is broken, the other end of the blocking part 22 opposite to the other end of the temperature sensing part 21 cannot be connected, that is, the other end of the blocking part 22 opposite to the other end cannot be connected to the top wall 15, so that the fixing is realized. And because the pressure inside the feed hole 11 is greater than the pressure outside the discharge hole 12, the blocking portion 22 can be driven by the pressure difference (the difference between the pressure inside the feed hole 11 and the pressure outside the discharge hole 12) to move towards the direction away from the feed hole 11, and at this time, one end of the blocking portion 22 will not abut against the side wall 14 of the housing 10 to form the accommodating space 13, that is, the blocking portion 22 will not block the feed hole 11, and finally the feed hole 11, the accommodating space 13, and the discharge hole 12 are communicated with each other, so as to provide a spraying channel for the fire extinguishing agent 4.
Referring to fig. 5 to 6 together, fig. 5 is a schematic sectional view of an actuation device for a fire extinguisher according to still another embodiment of the present application. Fig. 6 is a schematic view of the other end of the blocking portion opposite to the top wall abutting against the top wall in an embodiment of the present application. In this embodiment, the discharge 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 discharge hole 12 is smaller than a vertical distance between the other end of the blocking portion 22 opposite to the top wall 15.
In some embodiments, the feed opening 11 may be blocked by a blocking portion 22, thereby blocking the feed opening 11 from the discharge opening 12. In this 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, in the present embodiment, a vertical distance (as shown in a direction D1 in fig. 5) between one end of the blocking portion 22 and the discharging hole 12 may be smaller than a vertical distance (as shown in a direction D2 in fig. 5) between the other end of the blocking portion 22 opposite to the top wall 15. In this way, when the blocking portion 22 moves away from the feeding hole 11, that is, the opposite end of the blocking portion 22 moves away from the feeding hole 11, the vertical distance between the end of the blocking portion 22 and the discharging 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, the end of the blocking portion 22 may be completely clear of the outfeed aperture 12, which may also be understood as the blocking portion 22 being completely invisible within the outfeed aperture 12. Thus, the amount of the fire extinguishing agent 4 sprayed can be further increased, and the fire extinguishing effect can be improved.
Referring to fig. 7, fig. 7 is a schematic cross-sectional view of an actuation device of a fire extinguisher 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 sidewall 14, so as to divide 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-receiving space 131, and the feed opening 11 and the discharge opening 12 communicate with the second sub-receiving space 132.
In the present embodiment, after the blocking portion 22 moves under the driving of the pressure difference, the periphery of the blocking portion 22 can continuously abut against the sidewall 14, so that the blocking portion 22 can continuously partition the accommodating space to divide the accommodating space 13 into the first sub-accommodating space 131 and the second sub-accommodating space 132. The broken temperature sensing part 21 is disposed in the first sub-receiving space 131, and the inlet 11 and the outlet 12 communicate with the second sub-receiving space 132. This allows the broken temperature sensing part 21 to remain in the first sub-receiving space 131, thereby preventing the broken temperature sensing part 21 from entering the feed hole 11 from the second sub-receiving space 132 to affect the ejection of the fire extinguishing agent 4. The broken temperature sensing part 21 can be prevented from entering the discharge hole 12 from the second sub-receiving space 132 and being discharged, 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 actuating apparatus according to still another embodiment of the present application. In this embodiment, the opening size of the receiving space 13 close to the feeding hole 11 is smaller than the opening size of the receiving space 13 far from the feeding hole 11.
In this embodiment, the opening size of the accommodating space 13 close to the feeding hole 11 may be smaller than the opening size of the accommodating space 13 far from the feeding hole 11. This facilitates the blocking part 22 and the sidewall 14 to abut against each other to block and block the feed opening 11 and the discharge opening 12, and also facilitates the blocking part 22 to move toward a direction away from the feed opening 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 a direction close to the discharging hole 12, or the top wall 15 may move toward a direction away from the discharging hole 12.
This embodiment also allows the top wall 15 to be movably connected to the side wall 14, and it is also understood that the top wall 15 may be moved toward the direction close to the discharge opening 12, or the top wall 15 may be moved away from the discharge opening 12 (as shown in the direction D3 in fig. 8). Therefore, the temperature sensing element 20 is convenient to mount and dismount, and the vertical distance between one end of the blocking part 22 and the discharge hole 12 and the vertical distance between the other end, opposite to the blocking part 22, and the top wall 15 can be adjusted by the movement of the top wall 15.

When the actuating member 30 is used for applying an acting force to the temperature sensing element 20 when the ambient temperature reaches the second preset temperature, that is, one end of the actuating member 30 hits the temperature sensing element 20, so that the temperature sensing element 20 is broken by the external force, and finally the fire extinguishing agent 4 is sprayed out.
