[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a fine water mist fire extinguishing device, including a main body 1, a water storage bottle 2 and a high-pressure gas cylinder 4 on the main body 1, a support skirt 7 fixed to the bottom of the water storage bottle 2 by snap-fit ​​welding, and casters 8 evenly spaced and screwed to the bottom of the support skirt 7. This structure of the support skirt 7 provides stable support for the water storage bottle 2, and the main body 1 can be moved by the casters 8, facilitating the use of the main body 1. High-pressure water delivery hose 6 and high-pressure gas delivery hose 5 are respectively installed at the bottom of the water storage bottle 2 and the high-pressure gas cylinder 4. A U-shaped handle 3 is welded and fixed to one side of the support skirt 7, and a winding frame 18 is screwed to the side of the handle 3. The high-pressure water hose 5 and high-pressure air hose 6 are wound around the reel 18. This structure allows the main body 1 of the fire extinguishing device to be easily pushed by the handle 3. The high-pressure air hose 5 and high-pressure water hose 6 are easily stored by the reel 18, and a water filter 15 is installed on the high-pressure water hose 6. A spray gun 13 is installed on the main body 1 of the fire extinguishing device, and the spray gun 13 is connected to the other end of the high-pressure water hose 6 and the high-pressure air hose 5, respectively. The spray gun 13 is equipped with a control handle 14 and a grip handle 17. The outlet of the spray gun 13 is connected to a first spray bar 10 and a second spray bar 19 of different lengths through a hose structure. A locking positioning seat 11 is provided between the first spray bar 10 and the second spray bar 19. The locking positioning seat 11 has an I-shaped structure and engages... The positioning base 11 has grooves on both sides that are movably engaged with the first spray bar 10 and the second spray bar 19, respectively. This structure allows the two spray bars to be positioned relatively stably, ensuring that the first spray bar 10 and the second spray bar 19 are parallel to each other when the fire extinguishing device body 1 is not in use, thus preventing storage inconvenience. Furthermore, by setting the first spray bar 10 and the second spray bar 19 to different lengths, they can perform fire extinguishing operations over different ranges. The presence of the first spray bar 10 and the second spray bar 19 also increases the fire extinguishing range. Each of the first spray bar 10 and the second spray bar 19 has a nozzle 9 installed at its end. The upper and lower sides of the ends of the first spray bar 10 and the second spray bar 19 are respectively provided with an integral rotating base 12, and the rotating base 12 is connected to the spray bar 9. The housing of the gun 13 is rotatably snapped into place. An adjusting seat 20 is also rotatably inserted into the center of the inner side of the snap-in positioning seat 11. The adjusting seat 20 has two protrusions arranged symmetrically on its side, which respectively contact and cooperate with the first spray bar 10 and the second spray bar 19. This structure allows the adjusting seat 20 to rotate, so that the adjusting seat 20 can push the first spray bar 10 and the second spray bar 19 respectively through the protrusion structure. The first spray bar 10 and the second spray bar 19 can rotate relative to the spray gun 13 under the action of the rotating seat 12, thereby adjusting the angle of the first spray bar 10 and the second spray bar 19. The bottom of the snap-in positioning seat 11 is provided with an adjusting knob 16, and the adjusting knob 16 is fixed to the adjusting seat 20 with screws. This structure allows the adjusting seat 20 to be rotated through the adjusting knob 16.

[0019] Working principle: When using this fine water mist fire extinguishing device, first push the water storage bottle 2 with the handle 3, which allows the support skirt 7 to move the main body 1 of the fire extinguishing device under the action of the casters 8. When using the main body 1 of the fire extinguishing device for fire extinguishing, remove the high-pressure air hose 5 and high-pressure water hose 6 wound on the winding frame 18, and turn the adjustment knob 16 to make the adjustment seat 20 rotate relative to the locking positioning seat 11. This causes the protrusions on both sides of the adjustment seat 20 to push the first spray bar 10 and the second spray bar 19 to move, so that the first spray bar 10 and the second spray bar 19 are respectively on the rotating seat 12. The nozzle rotates relative to the spray gun 13 under the positioning, adjusts the angle of the first spray bar 10 and the second spray bar 19, and then picks up the spray gun 13 by holding the handle 17 and the control handle 14. The control handle 14 drives the main body 1 of the fire extinguishing device to use, so that the water and gas in the water storage bottle 2 and the high-pressure gas cylinder 4 are transmitted under high pressure through the high-pressure water supply hose 6 and the high-pressure gas supply hose 5 respectively. After the water filter 15 filters the high-pressure water, the high-pressure water and gas are sprayed out through the nozzles 9 at the ends of the first spray bar 10 and the second spray bar 19 respectively to form a fine water mist for fire extinguishing, thereby completing a series of operations.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
