[0034] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0035] Example 1:

[0036] See Figure 1 , 2 3. A flat fire extinguishing device includes a housing 10, a fire extinguishing agent 20, and an ignition device 30. The housing 10 is flat, the fire extinguishing agent 20 is disposed inside the housing 10, and the ignition device 30 extends from the outside of the housing 10 to the inside of the housing 10 and contacts the fire extinguishing agent 20. A nozzle 13 is provided on the side of the housing 10, and the nozzle 13 is a slot structure provided along the width or length of the housing 10.

[0037] By setting the nozzle 13 as a slot structure along the width or length of the housing 10, the effective coverage of the aerosol fire extinguishing device is wider, and the aerosol concentration in the fire extinguishing space can reach the required value more quickly.

[0038] The ignition device 30 is in contact with the extinguishing agent 20. In other words, the ignition device 30 and the extinguishing agent 20 can be in direct contact or indirect contact. For example, if the extinguishing agent 20 is wrapped with a plastic film, the ignition device 30 will be in contact with the plastic film outside the extinguishing agent 20.

[0039] like Figure 1 As shown, the housing 10 is a rectangular structure, and at least one nozzle 13 is provided on the width or length side of the housing 10. The nozzle 13 is a slot structure, that is, the nozzle 13 is not only provided on one side, but also extends to the two sides adjacent to this side.

[0040] Specifically, the extinguishing agent 20 is existing technology. In this embodiment, the extinguishing agent 20 is an aerosol extinguishing agent with a flat rectangular block structure. The shell 10 is made of 304 stainless steel.

[0041] In this embodiment, the ignition device 30 uses a thermal wire 31.

[0042] See Figure 6 The thermal wire 31 extends to the side of the extinguishing agent 20 facing the nozzle 13; wherein, the side of the extinguishing agent 20 facing the nozzle 13 is the activating surface, and the other sides are non-activating surfaces. The thermal wire 31 is prior art, for example, the thermal wire disclosed in CN216022877U.

[0043] The thermal wire 31 can pass through the housing 10 from the nozzle 13, or a wire hole 15 can be opened on the housing 10 and the thermal wire 31 can pass through the wire hole 15.

[0044] Furthermore, to improve the activation effect of extinguishing agent 20, see [link to relevant documentation]. Figure 6 A heat-sensitive wire 31 is installed along the entire length of the side of the extinguishing agent 20 facing the nozzle 13. In this way, the entire activation surface of the extinguishing agent 20 will be activated simultaneously, increasing the aerosol concentration.

[0045] See also Figure 6 When two nozzles 13 are arranged opposite each other on the housing 10, a wire hole 15 is provided on the side of the housing 10 between the two nozzles 13 to prevent the heat-sensitive wire 31 from igniting the non-activating surface of the extinguishing agent 20 near the wire hole 15. A partition 16 is also provided inside the housing 10, located on the non-activating surface of the extinguishing agent 20, and the heat-sensitive wire 31 extends from between the housing 10 and the partition 16 to the activating surface.

[0046] Example 2:

[0047] The difference from Embodiment 1 is that, in this embodiment, see Figure 1 , 27. The ignition device 30 is an electronic ignition head 32. The electronic ignition head 32 adopts existing technology, such as the electronic ignition head disclosed in CN216047830U.

[0048] Specifically, see Figure 7 The electronic ignition head 32 is installed on the side of the extinguishing agent 20 facing the nozzle 13. The side of the extinguishing agent 20 facing the nozzle 13 is the ignition surface. The wire 321 of the electronic ignition head 32 extends to the outside of the housing 10. With the above structure, the ignition surface can be ignited first.

[0049] The wire 321 can pass through the nozzle 13 and exit the housing 10, or a wire hole 15 can be opened on the housing 10 and the wire 321 can pass through the wire hole 15.

[0050] Furthermore, in Figure 7 In this configuration, the electronic ignition head 32 is located in the center of the extinguishing agent 20 activation surface, which is also equipped with a thermal wire 31 extending along its length. The electronic ignition head 32 ignites the extinguishing agent 20, which in turn ignites the thermal wire 31, which in turn ignites the entire activation surface, increasing the aerosol concentration.

[0051] Specifically, the electronic ignition head 32 may or may not be in contact with the thermal wire 31. When the electronic ignition head 32 is in contact with the thermal wire 31, the electronic ignition head 32 ignites the thermal wire 31 simultaneously with the extinguishing agent 20; when the electronic ignition head 32 is not in contact with the thermal wire 31, the electronic ignition head 32 first ignites the extinguishing agent 20, and the extinguishing agent 20 then ignites the thermal wire 31.

[0052] Example 3:

[0053] Based on Embodiment 1 or Embodiment 2, a cooling material 40 is filled inside the housing 10 on one side of the nozzle 13 to reduce the aerosol ejection temperature. In this embodiment, the cooling material 40 is a ceramic ball.

[0054] Example 4:

[0055] See Figure 3 , 4 5, 8, The housing 10 includes a bottom box 11 and a top cover 12. The extinguishing agent 20 and the ignition device 30 are installed inside the bottom box 11. The side of the top cover 12 is provided with a mounting seat 14. The top cover 12 is fastened to the bottom box 11. The top cover 12 and the bottom box 11 are connected and fixed by fasteners 17.

[0056] In this embodiment, as Figure 7As shown, the base box 11 and the top cover 12 have roughly the same structure. The top cover 12 is fastened onto the base box 11, and the nozzles 13 on the top cover 12 and the base box 11 are aligned. The top cover 12 and the base box 11 are connected and fixed by fasteners 17. Fasteners 17 include bolts or rivets. The mounting base 14 is used to install the fire extinguishing device in a designated position.

[0057] The method of use or principle of this utility model:

[0058] See Figure 6 , 7 When the ignition device 30 ignites the activation surface of the extinguishing agent 20, the extinguishing agent 20 generates an aerosol extinguishing medium. The aerosol extinguishing medium is sprayed out from the nozzle 13. Since the nozzle 13 is not only set on one side, but also extends to the two sides adjacent to this side, the effective coverage of the aerosol extinguishing device is wider, and the aerosol concentration in the extinguishing space can reach the required value more quickly.

[0059] See Figure 9 Figure a shows a flat-type fire extinguishing device in the prior art, and Figure b is a simulation diagram of the discharge of a flat-type fire extinguishing device in the prior art. As can be seen from Figure b, the existing technology has a low aerosol concentration, a small effective coverage area, and a poor discharge effect after 5 seconds of discharge.

[0060] See Figure 10 Figure c shows the flattened fire extinguishing device of this invention, and Figure d shows a simulation diagram of the spraying of the flattened fire extinguishing device of this invention. As can be seen from Figure d, the flattened fire extinguishing device of this invention has a high aerosol concentration after 5 seconds of spraying, and can also cover the corners, resulting in a wider effective coverage area and better spraying effect.
