[0002] Fire extinguishing balls have a high success rate in extinguishing initial fires in relatively enclosed spaces, preventing greater loss of life and property. In high-rise building areas and underdeveloped rural areas, fire scene conditions limit the ability of rescue forces to reach the scene immediately, and the fire situation is complex and rapidly changing, leaving people with little time to escape burning buildings. When evacuation routes are blocked by flames, the extinguishing agent sprayed from a thrown fire extinguishing ball can extinguish surrounding flames, buying escape space and time. Therefore, fire extinguishing balls have a significant advantage in opening safe evacuation routes and improving survival rates.
[0003] However, the existing methods for activating fire extinguishing balls are still somewhat complicated. In one known technical solution, the cap on the nozzle must first be unscrewed, then the on / off valve opened, before the fire extinguishing ball can be thrown. But in an emergency fire, people in distress are often in a state of panic, and this multi-step activation process greatly reduces the chances of safe escape.

[0035] Please refer to Figures 1 to 4 The embodiment provides a fire extinguishing ball, which comprises an inner container 3, an outer container and a striker 6, the inner container 3 is used for filling high-pressure gas and fire extinguishing agent, the inner container 3 is arranged in the inner container 3, the outer wall of the inner container 3 is connected with the inner wall of the outer container through elastic members 9, and at least two elastic members 9 are uniformly arranged on the outer periphery of the inner container 3; the outer container is provided with a spray head 8 which is communicated with the inside of the outer container and the outside; the inner container 3 is provided with a first opening 4, and the first opening 4 is provided with an elastic plug 5; the striker 6 is a hollow structure, one end of the striker 6 has a sharp structure, and the sharp structure penetrates into the elastic plug 5 in a non-through manner along the direction towards the inside of the outer container.
[0036] The working principle of the embodiment is as follows:
[0037] The inner container 3 for filling high-pressure gas and fire extinguishing agent and the outer container for wrapping the inner container 3 are arranged, the outer wall of the inner container 3 is connected with the inner wall of the outer container through at least two uniformly arranged elastic members 9, the elastic plug 5 is arranged at the first opening 4 of the inner container 3, the hollow striker 6 penetrates into the elastic plug 5 in a non-through manner, and when used, only the relative movement between the inner container 3 and the outer container is needed to make the bottom of the striker 6 collide with the inner wall of the outer container, so that the sharp structure of the striker 6 penetrates the elastic plug 5, and then the high-pressure gas and fire extinguishing agent in the inner container 3 are sprayed out of the inner container 3 along the hollow striker 6 and then sprayed to the outside from the spray head 8 of the outer container, so that the fire extinguishing is realized.
[0038] The relative movement between the inner container 3 and the outer container is the key to starting the embodiment, and there are various starting modes, for example, the fire extinguishing ball can be thrown out after being hit on the ground or wall under the condition that the spray head 8 is not aimed at the personnel, or the fire extinguishing ball can be directly thrown to the fire source, after the fire extinguishing ball collides with the ground or the obstacle, the inner container 3 does reciprocating movement in the outer container under the action of the elastic member 9, so that the bottom of the striker 6 collides with the inner wall of the outer container, and the starting of the fire extinguishing ball is completed.
[0039] In order to ensure that the striker 6 collides with the inner wall of the outer container during the process of hitting the fire extinguishing ball, a plurality of first openings 4, elastic plugs 5 and strikers 6 can be arranged on the inner container 3 and uniformly distributed along the outer periphery of the inner container 3. Similarly, the number of elastic members 9 can also be uniformly arranged to ensure the diversity of movement of the fire extinguishing ball in the process of multiple collisions. The elastic member 9 can be a spring, a rubber elastic body, a polyurethane elastic body, etc., and the spring is preferred in the embodiment.
[0040] As a preferred solution of the embodiment, the inner container is further provided with a guide pipe 7, one end of the guide pipe 7 is connected with the nozzle 8, and the other end is close to the end of the striker 6 which does not pierce the elastic plug 5. The guide pipe 7 can guide the high-pressure gas and fire extinguishing agent sprayed from the hollow striker 6 to flow quickly to the nozzle 8 and be sprayed outward. Experimental data show that after adding the guide pipe 7, the spraying distance of the fire extinguishing agent can reach two meters.
[0041] The fire extinguishing agent filled in the inner container 3 can be a conventional fire extinguishing agent in the prior art. The embodiment preferably uses a water-based fire extinguishing agent. Compared with other types of fire extinguishing agents, the water-based fire extinguishing agent has high cost performance, good fire extinguishing performance, can improve the actual fire extinguishing efficiency, and can maximize the damage to the ecological environment around the burning building, and has the advantage of environmental protection.
[0042] Embodiment two
[0043] Please refer to Figure 5 On the basis of embodiment one, the outer container in the embodiment includes an upper half 1 and a lower half 2, the upper half 1 and the lower half 2 are detachably connected, and the specific connection mode can adopt a conventional detachable connection mode in the prior art, such as threaded connection, clamping, quick connector connection, etc. The inner container 3 is provided with a second opening 10 and a sealing part 11, the second opening 10 and the sealing part 11 are detachably and sealingly connected, and the specific sealing connection mode can adopt a conventional detachable sealing connection mode in the prior art, such as sealing threaded connection, sealing clamping, sealing plug, etc.
[0044] By setting the outer container as a detachable upper half 1 and a lower half 2, and setting the inner container 3 with a second opening 10, the used fire extinguishing ball can be recycled. After recycling the used fire extinguishing ball, the outer container is opened to expose the first opening 4 and the second opening 10 of the inner container 3, the sealing part 11 at the second opening 10 is opened, the fire extinguishing agent is first filled into the inner container 3 from the second opening 10, after the sealing part 11 is closed, the high-pressure gas is filled into the inner container 3 through the hollow striker 6 at the first opening 4 by using the compressed gas cylinder, after the filling is completed, the striker is pulled out by half, the elastic characteristic of the elastic plug 5 will make the hole pierced by the striker 6 re-close to prevent the gas from flowing out, thus completing the re-filling of the fire extinguishing agent and the high-pressure gas, and the repeated use of the fire extinguishing ball can be realized.
[0045] In order to ensure the convenience of filling the fire extinguishing agent and the high-pressure gas, the first opening 4 and the second opening 10 are arranged close to each other, so that the first opening 4 and the second opening 10 can be exposed at the same time after the outer container is opened, and one of the openings is not located at a position close to the inside, and the inner container 3 cannot be rotated at a large angle due to the existence of the elastic member 9.
[0046] As a preferred solution of the embodiment, the outer container is further provided with a guide pipe 7, one end of the guide pipe 7 is connected with the nozzle 8, and the other end is close to the end of the striker 6 which does not pierce the elastic plug 5. The guide pipe 7 can guide the high-pressure gas and fire extinguishing agent sprayed from the hollow striker 6 to flow quickly to the nozzle 8 and be sprayed outward. Experimental data show that after adding the guide pipe 7, the spraying distance of the fire extinguishing agent can reach two meters.
[0047] As a preferred solution of the embodiment, the outer part of the lower half 2 is provided with a walking mechanism, which comprises a mounting frame and a directional wheel 15, the lower half 2 is detachably arranged on the upper part of the mounting frame, and the directional wheel 15 is rotatably arranged on the lower part of the mounting frame. The mounting frame comprises a bottom plate 14 and a support plate 13, at least two support plates 13 are arranged on the bottom plate 14, and the side of the support plate 13 away from the bottom plate 14 is provided with a support groove 16 for placing the lower half 2, and the groove surface of the support groove 16 is matched with the outer surface of the lower half 2.
[0048] By arranging the walking mechanism, after the fire extinguishing ball collides with the ground together with the walking mechanism and is pushed out towards the fire source, on the one hand, the spraying range of the fire extinguishing agent can be increased under the driving of the walking mechanism, and on the other hand, the stability of the walking mechanism can ensure the orientation of the nozzle 8 of the fire extinguishing ball stable, so as to avoid the embarrassing situation that the orientation of the nozzle 8 is far away from the position of the fire source after being thrown, or the fire extinguishing agent is directly sprayed towards the ground.
[0049] Since the fire extinguishing ball provided with the walking mechanism must adopt the starting mode of first collision and then pushing out, two points need to be additionally considered in the design:
[0050] First, the first opening 4 of the inner container 3 is as close to the walking mechanism as possible; the collision mode of the embodiment is essentially the same as that of the first embodiment, and the fire extinguishing ball can collide with the ground or a wall or any obstacle, but in order to reduce the operation steps, the preferred solution of the starting mode of the embodiment is to make the directional wheel 15 of the walking mechanism collide with the ground downward, and then directly push out without changing the operation direction.
[0051] Second, the setting direction of the nozzle 8 on the outer container must consider the safety of use; a plurality of nozzles 8 can be arranged on the outer container to cover as large a spraying area as possible, but a safety area must be reserved as an operation area for personnel, for example, the nozzle 8 can be arranged at a position in front of, on the side of, or on the side front of the fire extinguishing ball when the personnel is located behind the fire extinguishing ball.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0053] If the utility model discloses or involves mutually fixed connecting parts or structural members, then, except for another declaration, fixed connection can be understood as: detachable fixed connection (for example, bolt or screw connection), and also can be understood as: non-detachable fixed connection (for example, riveting, welding), of course, the mutually fixed connection can also be replaced by integral structure (for example, integrally formed by using casting process) (except for obviously unable to use integral forming process).
[0054] In addition, the terms used to represent the position relationship or shape in any of the technical solutions disclosed in the utility model above include the approximate, similar or close state or shape, except for another declaration.
[0055] Any component provided by the utility model can be assembled by multiple individual components, or can be an individual component manufactured by integral forming process.
