For the first sealing mode, some products can not detect the sealing performance of a sealing valve of a gas storage cylinder due to the fact that a high-pressure gas cylinder is arranged in the gas storage cylinder, so that possible pressure leakage is caused, and when the storage time is long, all or most of high-pressure gas in the gas storage cylinder can be leaked, so that the fire extinguishing function of the pressure storage type perfluorohexanone fire extinguishing device is invalid. For the second sealing mode, because the temperature difference in the fire-fighting area is large, the sealing film is easy to deform and loosen under the action of expansion with heat and contraction with cold, so that air leakage is caused, and the storage time of the high-pressure gas cylinder is short.

Detailed Description

The following description is further provided in conjunction with the accompanying drawings and the detailed description.

As shown in fig. 1 to fig. 3, the present embodiment provides a non-pressure-storage miniature fire extinguishing apparatus 100, comprising a flat box-shaped container 10 and a bursting apparatus 20 located in the container 10, wherein the container 10 is suitable for storing fire extinguishing substances such as perfluorohexanone, and the bursting apparatus 20 is suitable for instantly generating a large amount of gas when being started. At least one spout 11, preferably 2 in this embodiment, is disposed on one side of the container 10, the two spouts 11 are respectively sealed by a sealing film 12, an unsealing structure 30 is disposed in the container 10 near the sealing film 12, and the unsealing structure 30 is adapted to pierce the sealing film 12 under the air pressure generated by the actuation of the bursting device 20, so as to enable the fire extinguishing substance to be sprayed out from the spouts 11.

In this embodiment, an opening is disposed at one side of the container 10, the container 10 further includes a sealing cover 101 for closing the opening, and the at least one spout 11 is disposed on the sealing cover 101. During production of the product, the container 10 may be filled with a fire extinguishing substance through the opening, and then the sealing lid 101 is installed and sealed.

In order to enable the fire extinguishing substance to be sprayed out as completely as possible during fire extinguishing, a flow guide plate 102 is further fixed on the sealing cover 101 of the embodiment, one surface of the flow guide plate 102 facing the fire extinguishing substance is provided with a plurality of flow guide grooves 103, the cross sections of the flow guide grooves 103 are isosceles triangles, and the vertex angles of the isosceles triangles are located at the nozzles 11, so that the fire extinguishing substance completely enters the nozzles 11 under the action of high-pressure gas and the flow guide grooves 103 and is finally sprayed out, and the utilization rate of the fire extinguishing substance is improved.

To simplify the product structure, the sealing film 12 is located on the baffle plate 102, and specifically, the baffle plate 102 is located at the spout 11 and is configured as a film so as to facilitate piercing by the unsealing structure 30.

Further, a gap 40 is left between the unsealing structure 30 and the baffle 102, and the baffle 102 is adapted to allow the extinguishing substance to enter the spout 11 from the gap 40 under gas pressure and to be ejected from the spout 11. Thus, the fire extinguishing substance can be sprayed out completely, thereby improving the fire extinguishing effect.

The unsealing structure 30 is shown in fig. 4 and mainly comprises a sleeve 31 fixed on the inner wall of the container 10 and a piston 32 adapted to slide in the sleeve 31, the piston 32 comprises a striker 321 facing the sealing film 12 and a piston plate 322 fixing the striker 321, and a spring 33 for returning the piston plate 322 to an initial position is arranged between the piston plate 322 and the sleeve 31.

When the bursting device 20 is started, a large amount of gas is instantaneously generated, so that an ultrahigh pressure environment is rapidly formed in the container 10 from the bursting device 20 to the nozzle 11. Because the unsealing structure 30 is cylinder-shaped, the air pressure difference is generated on the two sides of the piston plate 322, the piston plate 322 moves towards the direction of small pressure under the action of the air pressure, and because the spout 11 is positioned on the side of small pressure, the piston plate 322 carries the striker 321 to move towards the spout 11 until the sealing film 12 at the spout 11 is punctured. After the sealing film 12 is punctured, the fire extinguishing substances in the sealing film are sprayed out from the nozzle 11 at a high speed under the pressure of ultrahigh pressure gas, so that high-efficiency fire extinguishing is realized.

In order to avoid the striker 321 from blocking the nozzle 11 during the fire extinguishing process, the embodiment further provides a pressure relief hole 34 in the unsealing structure 30, and specifically, one or more pressure relief holes 34 may be provided in the sleeve 31, and the pressure relief hole 34 is opened at the initial position of the piston plate 322, preferably, the piston plate 322 just blocks the pressure relief hole 34 when in the initial position. Thus, when the puncturing device 20 is activated, the piston plate 322 is rapidly pushed toward the nozzle 11 by the instantaneously generated high-pressure gas, and after the striker 321 fixed to the piston plate 322 punctures the sealing membrane 12, the piston plate 322 gradually returns to the initial position under the force of the spring 33 as the internal pressure difference gradually decreases. After the sealing film 12 is pierced, the piston plate 322 is no longer subjected to the gas pressure due to the pressure relief hole 34, and the piston plate 322 returns to the initial position rapidly under the force of the spring 33, so that the striker 321 does not stay in the gap 40 to block the flow of the fire extinguishing substance, and the fire extinguishing substance can be ejected smoothly and rapidly.

Referring to fig. 3 again, the bursting device 20 includes a thin-walled cylinder 21, an aerogenic agent 22 and a starter 23 for igniting the aerogenic agent 22 are hermetically disposed in the cylinder 21, and the starter 23 is an electric starter or a thermal starter. The electric starter generates high temperature after being connected with a power supply to ignite the gas generating agent 22, the thermal starter is a thermal element or a thermal wire, and the gas generating agent 22 can generate a large amount of gas instantly after being ignited by the heat generated by the electric starter or the thermal starter, so that the air pressure in the container 10 is increased rapidly.

For an electric starter such as an electric heater, the electric starter extends out of the cylinder 21 through an electric wire 24 and is connected with an external electric control device; for a thermal initiator such as a heat-sensitive wire, the thermal initiator extends to the outside of the cylinder 21 through the heat-sensitive wire, a wire end is led out for sensing the ambient temperature outside the cylinder 21, when a fire disaster occurs, the ambient temperature rises, the heat-sensitive wire is self-ignited and gradually burns along the heat-sensitive wire, until the gas-generating medicament 22 is ignited, and the bursting device 20 bursts.

In this embodiment, the hair-breaking device 20 is fixed on a side plate 104 of the container 10, and the side plate 104 is disposed opposite to the spout 11, that is, the sealing cover 101 where the spout 11 is located and the side plate 104 where the hair-breaking device 20 is located are two opposite side walls of the container 10, which are far away from each other, so as to facilitate buffering and transmission of internal pressure.

A blast guiding structure 13 (as shown in fig. 2) is disposed on the other side plate 105 adjacent to the side plate 104 where the bursting device 20 is located, wherein the blast guiding structure 13 is a groove or a seam opened on the side plate 105, and the seam is a welded seam or a riveted seam. When the internal pressure is too high, in order to avoid the potential safety hazard caused by random bursting of the container 10, the burst guide structure 13 provided in this embodiment may cause the product to directionally burst at the burst guide structure 13 due to the fact that the burst guide structure is thinner or the bonding force is weaker, thereby reducing the potential safety hazard to the greatest extent.

In addition, since the product is flat, in order to avoid deformation of the container 10 when the container is pressed, one or more reinforcing columns 14 are arranged inside the container 10, and the reinforcing columns 14 fix the upper wall and the lower wall of the container 10.

When the product is used for car power battery to put out a fire, because installation space is extremely limited, the deflection of product needs strict control, and the deformation of product can also further be avoided to the blasting guide structure 13 of this embodiment: when the air pressure in the container 10 is too high, the explosion venting guide structure 13 can be used for explosion venting, so that the container 10 is prevented from being expanded due to gas accumulation, and the power battery is extruded to cause the power battery to be short-circuited, so that secondary damage is caused.

In order to facilitate the installation and fixing of the product, the present embodiment further comprises a housing 50, the housing 50 is half-wrapped on the outside of the container 10, and is provided with a mounting hole 51 for installation and fixing, so that the product can be mounted on a wall, a ceiling or the inner and outer walls of the equipment, and the product can adapt to various fire extinguishing environments.

In summary, the container for storing the fire extinguishing substance is provided with the flat box body shape to reduce the volume of the product, meanwhile, the container is provided with the breaking device which can instantly generate a large amount of gas when being started, and the instant high pressure generated by the gas drives the unsealing structure to pierce the sealing film, so that the fire extinguishing substance is sprayed out from the nozzle under the gas pressure of the high-pressure gas, and the high-efficiency fire extinguishing is realized. On one hand, the volume of the fire extinguishing container is flat, light and thin, and the fire extinguishing container is convenient to use in narrow space, on the other hand, although the volume of the fire extinguishing container is small, high-pressure gas generated by the breaking device can enable fire extinguishing substances in the container to be sprayed out at high speed, so that efficient fire extinguishing is realized, and the fire extinguishing container has the advantages of volume and function, and is convenient to use in various occasions.
