[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] like Figures 1-2 As shown, this embodiment provides a backpack-type fine water mist fire extinguishing device, which includes a water tank 110, a support member 120, and a rotating assembly 130. A carrying strap 111 is mounted on the water tank 110, and a high-pressure fine water mist spray gun 112 is located on one side of the water tank 110. The support member 120 is installed on one side of the water tank 110 and supports the high-pressure fine water mist spray gun 112. The rotating assembly 130 drives the rotation of the support member 120. By carrying the water tank 110 on the back via the carrying strap 111, the burden of hand carrying is reduced. Furthermore, the rotating assembly 130 drives the support member 120 to rotate. When not in use, the rotating assembly 130 rotates the high-pressure fine water mist spray gun 112 mounted on the support member 120 to the side of the water tank 110 away from the carrying strap 111, facilitating transportation and movement. When needed, the rotating assembly 130 rotates the support member 120 towards the side closer to the carrying strap 111, making it easy to remove the high-pressure fine water mist spray gun 112 for fire extinguishing. This makes it convenient to use.

[0037] like Figures 1-4 As shown, in this embodiment, the carrier 120 includes a support plate 121 and a clamping member 122; the clamping member 122 is mounted on the support plate 121 and is used to fix and clamp the high-pressure fine water mist spray gun 112. By using the clamping member 122 to clamp the high-pressure fine water mist spray gun 112, it is possible to prevent the high-pressure fine water mist spray gun 112 from detaching from the water tank 110 when it moves with the water tank 110, thus preventing inconvenience in movement.

[0038] In this embodiment, the high-pressure fine water mist spray gun 112 is thinner in the middle and thicker at both ends, and is equipped with double handles for easy gripping.

[0039] like Figures 1-4As shown, in this embodiment, the clamping component 122 includes a circular ring 122a and a C-shaped retaining ring 122b; the C-shaped retaining ring 122b is an arc, the circular ring 122a and the C-shaped retaining ring 122b are coaxial, the circular ring 122a is located at the water spray end away from the high-pressure fine water mist spray gun 112, and the C-shaped retaining ring 122b is located in the middle of the high-pressure fine water mist spray gun 112; the high-pressure fine water mist spray gun 112 can be clamped on the circular ring 122a and the C-shaped retaining ring 122b. During clamping, first, the narrower middle part of the high-pressure fine water mist spray gun 112 is engaged with the C-shaped retaining ring 122b. Then, the high-pressure fine water mist spray gun 112 is moved towards the circular ring 122a, causing the non-spraying end of the high-pressure fine water mist spray gun 112 to move into the circular ring 122a and be secured. After the high-pressure fine water mist spray gun 112 moves, the C-shaped retaining ring 122b also secures the high-pressure fine water mist spray gun 112. The circular ring 122a and the C-shaped retaining ring 122b prevent the high-pressure fine water mist spray gun 112 from being disengaged, thus affecting its movement. The circular ring 122a has a rubber layer inside, which prevents the high-pressure fine water mist spray gun 112 from easily disengaging from the circular ring 122a, further ensuring that the high-pressure fine water mist spray gun 112 does not detach from the circular ring 122a and the C-shaped retaining ring 122b.

[0040] In other embodiments, a magnet is provided on the inner side of the ring, and an iron sheet or iron block, which can also be a magnet, is provided on the high-pressure fine water mist spray gun 112. This also prevents the high-pressure fine water mist spray gun 112 from easily detaching from the ring 122a, and further ensures that the high-pressure fine water mist spray gun 112 does not detach from the ring 122a and the C-shaped retaining ring 122b.

[0041] like Figures 1-2 as well as Figures 4-5 As shown, in this embodiment, the fire extinguishing device 100 also includes a carrier 140, which is located on the side of the support plate 121 away from the clamping member 122, and is used for temporary placement of the high-pressure fine water mist spray gun 112. That is, after using the high-pressure fine water mist spray gun 112 to extinguish a fire, since the high-pressure fine water mist spray gun 112 has a certain weight, it can be placed on the carrier 140, which can temporarily free up the hands to perform other work or take a short rest.

[0042] In this embodiment, there are two carriers 140. Each carrier 140 is an arc-shaped component with a minor arc, and the two carriers 140 are coaxial. The minor arc design effectively ensures that the high-pressure fine water mist spray gun 112 will not easily detach from the carrier 140, thus increasing stability.

[0043] In some embodiments, a specially designed adsorption element is configured on the carrier 140. When the high-pressure fine water mist spray gun 112 is placed on the carrier 140, the adsorption element can tightly adsorb the high-pressure fine water mist spray gun 112 through its own adsorption. This adsorption can effectively increase the friction and adhesion between the high-pressure fine water mist spray gun 112 and the carrier 140, making the high-pressure fine water mist spray gun 112 more stable on the carrier 140. It will not easily shift or detach due to slight external impact or vibration. Thus, even if a certain degree of shaking occurs during the movement or walking of the equipment, the high-pressure fine water mist spray gun 112 can remain stable and will not fall off due to shaking. This ensures the safety and reliability of the equipment during use, avoids malfunctions or safety hazards caused by the spray gun falling off, and improves the overall stability and ease of operation of the equipment during use.

[0044] In some embodiments, the adsorption element may be a suction cup.

[0045] In other embodiments, the adsorption element may also be a magnet.

[0046] In this embodiment, a specially designed control assembly is configured on the support plate 121. The main function of this control assembly is to control the start and stop operation of the high-pressure fine water mist spray gun 112. When the rotating assembly 130 drives the carrier 120 to rotate towards the side closer to the carrying strap 111, the position and angle of the control assembly will change accordingly, placing it in a state that is more convenient for the operator to operate and observe. In this way, when the operator needs to remove the high-pressure fine water mist spray gun 112 for fire extinguishing operations, they can quickly operate the switch through the control assembly, greatly shortening the time from removing the spray gun to starting to spray fine water mist, thereby facilitating rapid response to fires and efficient fire extinguishing operations.

[0047] This design not only improves operational convenience but also ensures that in emergencies, operators can quickly deploy the high-pressure fine water mist spray gun 112 to extinguish fires and minimize losses. The control components may feature an intuitive interface and clear indicators, facilitating accurate operation in various environments and further enhancing the equipment's practicality and reliability.

[0048] In some embodiments, the control component is located on one side of the support plate 121 and the carrier 140, which facilitates temporary placement and enables efficient start and stop of the high-pressure fine water mist spray gun 112.

[0049] like Figures 1-6As shown, in this embodiment, the rotating assembly 130 includes a support member 131, a first rotating member 132, and a second rotating member 133; the first rotating member 132 is mounted on the support member 131 and is used to rotate the clamping member 122 toward the side of the water tank 110 where the carrying strap 111 is mounted; the second rotating member 133 is mounted on the first rotating member 132 and is used to rotate the side of the support plate 121 with the carrier 140 upward. The rotation of the first rotating component 130 ensures that when not in use, the first rotating component 132 rotates the high-pressure fine water mist spray gun 112 mounted on the carrier 120 to the side of the water tank 110 away from the shoulder strap 111, facilitating transportation and movement. When needed, the first rotating component 132 rotates the carrier 120 towards the side closer to the shoulder strap 111, making it easy to remove the high-pressure fine water mist spray gun 112. The use of the second rotating component 133 allows the support plate 121 to rotate upward on the side with the carrier 140, ensuring that the high-pressure fine water mist spray gun 112 can be placed on the carrier 140 later, temporarily freeing up the hands.

[0050] like Figures 1-4 As shown, in this embodiment, the support member 131 is provided with an arc-shaped groove, and the first rotating member 132 is provided with a cylindrical block. The cylindrical block is placed in the arc-shaped groove. When the first rotating member 132 rotates, the arc-shaped groove restricts the first rotating member 132 from continuing to rotate. By using the arc-shaped groove to restrict the first rotating member 132, the first rotating member 132 can prevent the carrier member 120 from continuing to rotate after rotating towards the side closer to the shoulder strap 111, making it easier to remove the high-pressure fine water mist spray gun 112.

[0051] In some embodiments, the support member 131 is equipped with a forward and reverse motor, which is a three-phase asynchronous motor that can drive the first rotating member 132 to rotate. Using a forward and reverse motor allows for more precise control of the rotation of the first rotating member 132, making operation more convenient.

[0052] like Figures 4-6 As shown, in this embodiment, the first rotating member 132 and the support member 131 can be fixed by magnetic attraction 134; the first rotating member 132 and the second rotating member 133 can be fixed by magnetic attraction 134. This ensures that when not in use, after the first rotating member 132 rotates the high-pressure fine water mist spray gun 112 mounted on the carrier member 120 to the side of the water tank 110 away from the shoulder strap 111, the carrier member 120 will not easily rotate under the attraction of the magnet 134, thus ensuring that the high-pressure fine water mist spray gun 112 is fixed on the side of the water tank 110 away from the shoulder strap 111.

[0053] In some embodiments, the first rotating member 132 is provided with a ball-head pin, and the support member 131 is provided with a countersunk hole. When not in use, the first rotating member 132 rotates the high-pressure fine water mist spray gun 112 mounted on the carrier member 120 to the side of the water tank 110 away from the shoulder strap 111. The ball-head pin on the first rotating member 132 is then placed in the countersunk hole, preventing the first rotating member 132 from rotating easily, thereby ensuring that the high-pressure fine water mist spray gun 112 does not rotate easily and facilitating movement. Similarly, the support plate 121 is provided with a ball-head pin, and the first rotating member 132 is provided with a countersunk hole. When the ball-head pin on the support plate 121 moves into the countersunk hole on the first rotating member 132, it further ensures that the high-pressure fine water mist spray gun 112 does not rotate easily and further ensures that movement is facilitated.

[0054] The device is operated by first carrying it on the back using the shoulder strap 111, then quickly carrying it to the fire scene. The magnet 134 attracts the first rotating component 132 and the support component 131, and the second rotating component 133 and the first rotating component 132, respectively, ensuring that they do not easily rotate during transport and allowing for rapid arrival at the fire scene. Upon arrival, to extinguish the fire, the second rotating component 132 is rotated to move the support plate 121 towards the shoulder strap 111, i.e., towards the front. After rotation, the high-pressure fine water mist spray gun 112 is positioned in front, allowing for quick removal. After removal, the second rotating component 133 is rotated to rotate the side of the support plate 121 with the carrier 140 upwards, displaying the control components in an easily observable area. The high-pressure fine water mist spray gun 112 can then be activated to begin firefighting operations. When a temporary rest is needed, or when performing other operations, such as dragging debris, simply place the high-pressure fine water mist spray gun 112 on the carrier 140, and under the action of the adsorption component, the high-pressure fine water mist spray gun 112 will not easily separate.

[0055] In summary, this utility model provides a backpack-type fine water mist fire extinguishing device. When not in use, the rotating component rotates the high-pressure fine water mist spray gun mounted on the carrier to the side of the water tank away from the carrying strap, facilitating transportation and movement. When needed, the rotating component rotates the carrier to the side closer to the carrying strap, making it easy to remove the high-pressure fine water mist spray gun for fire extinguishing, making it convenient to use.
