When using this nozzle, after the device is started and the gas generating agent generates a large amount of gas, the air flow can be ejected from the nozzles in three directions during the eruption process, improving the fire extinguishing efficiency.

[0003] However, the manufacturing process of the four-way pipe fitting is relatively complex, and the price is relatively high, which is not suitable for some occasions with low cost requirements. In addition, the four-way copper pipe fitting needs to be welded, and is easily corroded, thus affecting the sealing performance. Moreover, the installation and maintenance of the four-way pipe fitting are difficult. Due to the structural characteristics of the four-way pipe fitting, it is easily affected by lateral forces, and attention needs to be paid to avoiding the action of lateral forces during installation and use. And when installing and maintaining the four-way pipe fitting, factors such as pipe joints, gaskets, and bolts need to be considered, which is difficult and requires certain professional knowledge and skills.

Detailed implementation manner

[0024] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant attached drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] It can be understood that spatial relationship terms such as "under", "below", "lower", "beneath", "above", "upper", etc. can be used herein to describe the relationship between an element or feature shown in the figure and other elements or features. It should be understood that in addition to the orientation shown in the figure, spatial relationship terms also include different orientations of the device during use and operation. For example, if the device in the drawing is flipped, the element or feature described as "under other elements" or "beneath it" or "under it" will be oriented "above" other elements or features. Therefore, the exemplary terms "under" and "below" can include both the upper and lower orientations. In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial description terms used herein are accordingly interpreted.

[0027] An efficient hot aerosol fire extinguishing device, as Figure 2 shown, includes an outer shell 1, and a reaction chamber 2, a cooling chamber 3, and a discharge chamber 4 are sequentially arranged in the outer shell 1 from bottom to top.

[0028] As Figure 3 shown, an aerosol generating agent 21 and a starting mechanism 6 are arranged in the reaction chamber 2, and the starting mechanism 6 is used to start the aerosol generating agent 21. Silica gel coating layers 22 are arranged around and at the bottom of the aerosol generating agent 21 to isolate the aerosol generating agent 21 from the outer shell 1 and prevent the outer shell 1 from overheating when the aerosol generating agent 21 reacts to generate gas.

[0029] In addition, a partition net 23 is provided at the top of the aerosol generating agent 21. The partition net 23 is used to isolate the coolant 31 and the aerosol generating agent 21, preventing the heat released by the activation mechanism 6 from being absorbed by the coolant 31, and can maximize the startup success rate of the fire extinguishing device. And a cavity is formed inside the partition net 23, and the activation mechanism 6 is arranged inside the cavity, so as to ensure that the top of the aerosol generating agent 21 starts first, and ensure that the aerosol generating agent 21 reacts gradually from the top to the bottom.

[0030] In this embodiment, the activation mechanism 6 includes an activation medicine package 61, an ignition head 62 and an activation wire harness 63. The ignition head 62 is arranged inside the activation medicine package 61. One end of the activation wire harness 63 is connected to the ignition head 62, and the other end extends out of the housing 1 from the bottom of the housing 1. In addition, the bottom of the aerosol generating agent 21 is connected to the inner wall of the bottom of the housing through a plurality of support pads 24, preventing the aerosol generating agent 21 from tightly pressing the bottom of the housing 1 and damaging the activation wire harness 63.

[0031] The cooling chamber 3 is provided with a coolant 31, which is used to absorb the heat released by the aerosol fire extinguishing agent, so that the temperature of the aerosol fire extinguishing agent is as low as possible, and reduce the flame ejection at the nozzle. The coolant 31 can be a physical coolant or a chemical coolant, which is not limited here.

[0032] As Figure 4 shown, the top of the spraying chamber 4 is provided with a top nozzle 41, and the side wall of the spraying chamber 4 is provided with a plurality of side nozzles 42. In this embodiment, two side nozzles 42 are oppositely arranged on the side wall of the spraying chamber 4, so that the aerosol fire extinguishing agent can be ejected from three different directions at the same time, improving the fire extinguishing efficiency. And compared with the existing three-way structure nozzle, the fire extinguishing device of this embodiment has a simple structure, low cost, does not require welding, is more corrosion-resistant, is not easily affected by lateral forces at the same time, and is convenient to install.

[0033] In addition, a partition 5 is arranged between the cooling chamber 3 and the spraying chamber 4, and a 51 is arranged on the partition 5. The bottom of the partition 5 is covered with a mesh pad 52, and the spraying chamber 4 is filled with a wire mesh 43.

[0034] If the coolant 31 adopts a physical coolant, such as ceramic balls, when the pressure of the fire extinguishing device near the aerosol generating agent 21 is too high, the ceramic balls will push the mesh pad 52, causing the mesh pad 52 to bend and deform, resulting in the coolant 31 entering the area where the wire mesh 43 is located, thereby slowing down the spraying pressure of the fire extinguishing device. In addition, the wire mesh 43 will absorb heat during normal spraying, which can not only prevent the ceramic balls from blocking the nozzles but also play a cooling role, and can also ensure that the ceramic balls will not damage the nozzles of the fire extinguishing device due to hitting the nozzles.

[0035] When the coolant 31 uses a chemical coolant, if the coolant 31 melts and solidifies together, the spacer net 23 and the wire mesh 43 can also prevent the solidified coolant 31 from blocking the gap between the partition plate 5 and the housing.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
