[0026] The technical solutions in the embodiments of the present application will be described below with reference to the drawings of the embodiments of the present application.

Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0028] In addition, in the present application, the orientation terms such as "up", "down", and the like are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0029] In the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0030] As Figures 1 to 3 shown, the embodiment of the present application provides a double-cavity jet type silicon-based gel foam fire extinguisher. Referring to Figure 1 and Figure 2 , the double-cavity jet type silicon-based gel foam fire extinguisher can include: a first high-pressure gas cylinder 1, a second high-pressure gas cylinder 2, a first siphon 3, a second siphon 4, a first valve 5, a second valve 6, a connected pressure handle 7, and a jet assembly,

[0031] wherein the first high-pressure gas cylinder 1 and the second high-pressure gas cylinder 2 are fixedly connected, the first valve 5 and the second valve 6 are respectively installed at the bottle mouths of the first high-pressure gas cylinder 1 and the second high-pressure gas cylinder 2, and the first siphon 3 and the second siphon 4 are respectively installed at the bottom ends of the first valve 5 and the second valve 6; the two ends of the connected pressure handle 7 are respectively connected to the top ends of the first valve 5 and the second valve 6, for pressing the valve stems of the first valve 5 and the second valve 6; the jet assembly includes a spray pipe 17 and a nozzle 8, the spray pipe 17 includes a mixing pipe section and two branch pipes, one end of the mixing pipe section is communicated with the nozzle 8, and the other end of the mixing pipe section is connected to the first valve 5 and the second valve 6 through the two branch pipes respectively.

[0032] The first high-pressure gas cylinder 1 stores liquid component A and high-pressure gas, and the second high-pressure gas cylinder 2 stores liquid component B and high-pressure gas; the first siphon 3 and the second siphon 4 are provided with gas holes 12 corresponding to the positions of the high-pressure gas. The high-pressure gas in the first high-pressure gas cylinder 1 is located above the component A, and the high-pressure gas in the second high-pressure gas cylinder 2 is located above the component B. As Figure 2 shown, the liquid level 20 is the dividing line of the component B and the high-pressure gas 11.

[0033] Therefore, by storing component A and component B in two high-pressure gas cylinders respectively, and storing high-pressure gas in both high-pressure gas cylinders, when the connected pressure handle 7 is pressed, component A and component B are mixed in the spray pipe 17 under the action of the high-pressure gas to form a silicon-based foaming gel. And by the way of punching gas holes 12 on the upper ends of the two siphons, component A and component B are mixed with high-pressure gas in the process of entering the spray pipe 17 (which improves the flowability of the gel while having a high foaming expansion ratio), and by changing the size of the gas hole 12, the effect of the jet foam can be adjusted.

[0034] It can be understood that by pressing the integrated handle 7, the valve stems of the first valve 5 and the second valve 6 can be pressed at the same time, and the high-pressure gas in the first high-pressure cylinder 1 will press the component A into the first siphon pipe 3, and the pressed component A will be mixed with the mixed high-pressure gas to reach one branch of the spray pipe 17; similarly, the high-pressure gas in the second high-pressure cylinder 2 will press the component B below the cylinder into the second siphon pipe 4, and the pressed component B will be mixed with the mixed high-pressure gas to reach another branch of the spray pipe 17; even if the component A in the first high-pressure cylinder 1 flows from the component A outlet 13 to the merging outlet 15, and the component B in the second high-pressure cylinder 2 flows from the component B outlet 14 to the merging outlet 15, so that the different components of the first high-pressure cylinder 1 and the second high-pressure cylinder 2 enter the spray pipe 17 at the same time, and the effective guarantee of the uniform mixing of the components A and B in the spray pipe 17 through the spray assembly ensures that the chemical reaction of the components A and B occurs uniformly, and after sufficient reaction, the silicon-based foaming gel is sprayed out for extinguishing various fires such as oil pools, electrical appliances, photovoltaic panels, and metal dust.

[0035] It should be noted that: the silicon-based foam extinguishing agent is usually prepared by the reaction of two liquids, which are commonly referred to as component A (A liquid) and component B (B liquid) in the chemical and fire fighting fields. Component A and component B are known substances. Component A is a solution containing silicate, and component B is a solution containing an acidic catalyst. After mixing with gas, component A and component B form a semi-gel state in the spray pipe, and after being sprayed from the spray pipe, they can quickly adhere to the extinguishing object to form a solid gel for extinguishing. For example, the extinguishing agent disclosed in the applicant's prior application CN118543065A can be used.

[0036] In some embodiments, the components of component A and their mass percentages are: inorganic silicate: 18% to 25%; sodium carboxymethyl cellulose: 0.25%; sodium alginate: 0.25%; xanthan gum: 0.1% to 0.5%; polyvinyl alcohol: 0.5% to 1%; sodium dodecyl sulfate: 0.5% to 1.5%; dodecanol: 0.01% to 0.05%; disodium ethylenediaminetetraacetate: 0.005% to 0.01%; and the balance is water. The components of the second liquid extinguishing agent 10 and their mass percentages are: sodium dihydrogen phosphate: 25%; acetic acid: 25%; fatty alcohol polyoxyethylene ether: 1% to 1.5%; 3% AFFF: 0.1 to 0.5%; dodecanol: 0.01% to 0.05%; and the balance is water.

[0037] Component A is prepared by a method comprising the following steps: dissolving inorganic silicate in water under stirring, slowly adding sodium carboxymethyl cellulose, and stirring to disperse and dissolve quickly, then adding sodium alginate, xanthan gum, polyvinyl alcohol, disodium ethylenediaminetetraacetate, and dodecanol, and finally adding sodium dodecyl sulfate. Stirring is continued for 60 minutes to 120 minutes until all components are dissolved to form component A.

[0038] Component B is prepared by a method comprising the following steps: pour sodium dihydrogen phosphate, dodecanol into water and stir, then add fatty alcohol polyoxyethylene ether, acetic acid and 3% AFFF, continue to stir for 30-60 min until all are dissolved to form component B.

[0039] The method for using the fire extinguisher of the embodiment includes:

[0040] Press the integrated handle 7 to press the valve stems of the first valve 5 and the second valve 6 at the same time, so that the high-pressure gas in the first high-pressure cylinder 1 press component A 9 into the first siphon tube 3, and the component A 9 in the first siphon tube 3 reaches the nozzle 8 after mixing with the high-pressure gas mixed through the air hole 12 on the first siphon tube 3; and the high-pressure gas in the second high-pressure cylinder 2 press component B 10 into the second siphon tube 4, and the component B 10 in the second siphon tube 4 reaches the nozzle 8 after mixing with the high-pressure gas mixed through the air hole 12 on the second siphon tube 4; the two fluids flowing into the nozzle 17 mix and chemically react in the nozzle 17 to form a silicon-based foaming gel, which is sprayed out of the nozzle 8.

The air hole 12 on the first siphon tube 3 is located at the upper position of the pipe section corresponding to the high-pressure gas.
