[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] The following describes the back-mounted fire extinguishing device 100 according to the present application with reference to the accompanying drawings.

[0040] like Figures 1 to 3 As shown, a specific embodiment of the present application provides a backpack fire extinguishing device 100, including a fire extinguishing agent container 1 and an installation box 2, wherein a box cavity is provided in the installation box 2 and a plug interface connected to the box cavity is opened on the peripheral side, the fire extinguishing agent container 1 can be detachably loaded into the box cavity of the installation box 2 from the plug interface, and a limiting structure 3 for fixing the fire extinguishing agent container 1 in the installation box 2 is provided between the installation box 2 and the fire extinguishing agent container 1.

[0041] Specifically, the installation box 2 is carried by the firefighters into the fire scene, and the firefighters carry multiple fire extinguishing agent containers 1 filled with fire extinguishing agent. In the present application, the fire extinguishing agent is replenished by replacing the fire extinguishing agent container 1 in the installation box 2, so that the firefighters do not need to leave the fire scene to replenish the fire extinguishing agent, thereby saving a lot of time and manpower to improve the fire extinguishing efficiency.

[0042] Furthermore, when replacing the fire extinguishing agent container 1, the firefighters need to cooperate with each other. If the plug-in port is opened on the top of the installation box 2, it is inconvenient for the firefighters to take out the fire extinguishing agent container 1 from the top, and the firefighters carrying the installation box 2 need to squat or remove the installation box 2. In the present application, the replacement of the fire extinguishing agent container 1 is facilitated by opening the plug-in port on the side of the installation box, thereby saving operation time and improving the fire extinguishing efficiency of the backpack fire extinguishing device 100.

[0043] Furthermore, the limiting structure 3 is provided to prevent the fire extinguishing agent container 1 from falling out of the installation box 2, thereby improving the safety and practicality of the backpack fire extinguishing device 100.

[0044] It should be noted that the peripheral side of the installation box 2 refers to all side positions except the top and bottom. For example, the installation box 2 is a cubic structure, the upper top surface is the top, the lower bottom surface is the bottom, and the front side, rear side, left side and right side are the peripheral side.

[0045] The following specific embodiments are described with the installation box 2 and the fire extinguishing agent container 1 being both cubic structures, that is, the installation box 2 and the fire extinguishing agent container 1 both include a top, a bottom, a front side, a rear side, a left side, and a right side. It can be understood by those skilled in the art that, in addition to the cubic structure, other structural forms of the installation box 2 should also fall within the scope of protection of this application. In the specific embodiments of this application, "front", "rear", "left", and "right" refer to the directions of the sides of the installation box 2, and "up" and "down" refer to the directions of the top and bottom, respectively.

[0046] In some embodiments, the inner wall of the installation box 2 is provided with a sliding structure extending along the insertion direction, and the fire extinguishing agent container 1 is slidably matched with the sliding structure.

[0047] Specifically, the inner wall of the installation box 2 refers to the top, bottom and peripheral sides of the installation box 2 facing the box cavity. The insertion direction and path of the fire extinguishing agent container 1 are limited by setting a sliding structure, thereby facilitating the installation and removal of the fire extinguishing agent container 1.

[0048] Preferably, the sliding structure includes a protrusion 6 arranged on the left side and / or the right side of the installation box 2, and a groove 7 for slidingly cooperating with the protrusion 6 is correspondingly formed on the left side and / or the right side of the fire extinguishing agent container 1. The shape of the protrusion 6 includes a variety of shapes such as "T-shaped", "I-shaped" and "angle-shaped", and the shape of the groove 7 corresponds to the shape of the protrusion 6.

[0049] Furthermore, the protrusion 6 is integrally formed with the mounting box 2 during the processing of the mounting box 2, and the groove 7 is integrally formed with the fire extinguishing agent container 1 during the processing of the fire extinguishing agent container 1, thereby improving the integrity of the backpack fire extinguishing device 100 and reducing the assembly steps.

[0050] In some embodiments, a shoulder strap 4 is provided on the rear side of the installation box 2, and an insertion port is provided on the front side of the installation box 2. The firefighter carries the installation box 2 by means of the shoulder strap 4, with the rear side of the installation box 2 facing the firefighter's back and the insertion port on the front side facing away from the firefighter, so that the firefighter does not need to remove the installation box 2 to install or remove the fire extinguishing agent container 1, thereby facilitating the installation or removal of the fire extinguishing agent container 1.

[0051] Preferably, the front side of the installation box 2 is open, and the front side of the fire extinguishing agent container 1 covers the front side of the installation box 2, that is, the fire extinguishing agent container 1 is embedded in the installation box 2, thereby reducing the weight of the installation box 2 to achieve lightweight backpack fire extinguishing device 100, thereby reducing the weight of firefighters.

[0052] Preferably, a carrying handle 13 is provided on the front side of the fire extinguishing agent container 1 , and firefighters carry the fire extinguishing agent container 1 through the carrying handle 13 , thereby facilitating the rapid installation and removal of the fire extinguishing agent container 1 and the installation box 2 .

[0053] In some embodiments, the limiting structure 3 includes a spring latch 31 and a lock 32, and the installation positions of the spring latch 31 and the lock 32 are arranged according to the relative positions of the front side of the protrusion 6 and the front side of the fire extinguishing agent container 1 along the front-to-back direction when the fire extinguishing agent container 1 is installed.

[0054] Specifically, when the fire extinguishing agent container 1 and the installation box 2 are installed, the front side of the protrusion 6 and the front side of the fire extinguishing agent container 1 are located in the same vertical plane, the spring latch 31 is arranged on the front side of the fire extinguishing agent container 1, and the lock buckle 32 is arranged on the front side of the protrusion 6; the front side of the protrusion 6 is located on the front side of the front side of the fire extinguishing agent container 1, the spring latch 31 is arranged on the front side of the fire extinguishing agent container 1, and the lock buckle 32 is arranged on one of the left and right sides of the protrusion 6 facing the spring latch 31; the front side of the protrusion 6 is located on the rear side of the front side of the fire extinguishing agent container 1, the spring latch 31 is arranged on the front side of the protrusion 6, and the lock buckle 32 is arranged on one of the left and right sides of the fire extinguishing agent container 1 facing the spring latch 31.

[0055] like Figure 4As shown, further, the spring latch 31 includes a fixed shell, a latch rod 311, and a button paddle 312, wherein the latch rod 311 passes through the fixed shell, and an annular protrusion 313 is formed on the outer peripheral wall of the latch rod 311, and the insertion and removal of the latch rod 311 is limited by the abutment between the button paddle 312 and the annular protrusion 313, and the insertion and removal of the latch rod 311 is restored by separating the button paddle 312 and the annular protrusion 313.

[0056] Preferably, a spring 314 is sleeved on the latch rod 311, one end of the spring 314 is connected to the latch rod 311, and the other end is connected to the fixed shell. Under the elastic action of the spring 314, the latch rod 311 has a tendency to be pulled out of the lock buckle 32. When the button paddle 312 and the annular protrusion 313 are separated, the latch rod 311 can automatically disengage from the lock buckle 32, thereby improving the convenience of the backpack fire extinguishing device 100.

[0057] Preferably, the number of the spring latches 31 and the lock catches 32 is plural, preferably two, and the two spring latches 31 are symmetrically arranged, and the two lock catches 32 are symmetrically arranged.

[0058] It should be noted that the structures and connection relationship of the spring latch 31 and the lock catch 32 are well known to those skilled in the art, and are not part of the core improvement of the present application, so they will not be described here. It can be understood by those skilled in the art that the position limiting structure 3 of the present application is not limited to the above-mentioned spring latch 31 and lock catch 32, and can also be other structural forms such as buckles that can achieve the position fixation of the fire extinguishing agent container 1 and the installation box 2, which should also fall within the scope of protection of the present application.

[0059] In some embodiments, a filling port is provided on the top of the fire extinguishing agent container 1, and a sealing cover 12 is sealed on the filling port. The top of the installation box 2 is open, and the fire extinguishing agent is replenished through the top filling port, thereby realizing the reuse of the fire extinguishing agent container 1 and adding a way to replenish the fire extinguishing agent, that is, the fire extinguishing agent container 1 does not need to be replaced but the fire extinguishing agent can be directly added to the fire extinguishing agent container 1.

[0060] In some embodiments, a water pump box 8 equipped with a water pump 9 is provided below the installation box 2, the liquid inlet of the water pump 9 is connected to the liquid outlet of the fire extinguishing agent container 1 by water, the liquid outlet of the water pump 9 is connected to the spray gun 10, and the liquid outlet of the water pump 9 is connected to the spray gun 10 through a hose 14.

[0061] Specifically, a control module 15, a battery 16 and a switch 17 are also installed in the water pump box 8. The battery 16 is used to power the control module 15 and the water pump 9.
