As shown in fig. 1 and 2, a fire extinguishing apparatus 100 according to an embodiment of the present invention includes a fire extinguishing bottle 10, a flexible spray pipe 20, and a float 30.

The fire extinguishing bottle 10 has the holding chamber 11 and the jet orifice that communicates with the holding chamber 11, and holding chamber 11 is used for storing fire extinguishing medium and compressed gas, and flexible injection pipe 20 sets up in holding chamber 11, and the one end sealing connection of flexible injection pipe 20 is in the jet orifice department of fire extinguishing bottle 10 to with the jet orifice intercommunication, float piece 30 runs through and has seted up connecting channel 31, and the one end that the jet orifice was kept away from to flexible injection pipe 20 is connected in connecting channel 31.

Wherein the float member 30 is configured to float on the extinguishing medium and the end of the connecting channel 31 remote from the flexible injection tube 20 is immersed in the extinguishing medium.

By arranging the fire extinguishing device, in case of fire, the fire extinguishing medium enters from one end of the connecting channel 31 far away from the flexible spraying pipe 20, then passes through the connecting pipe 33 and the flexible spraying pipe 20 in sequence, and finally is sprayed out from the spraying opening to extinguish fire. Because the connecting channel 31 is far away from the flexible spraying pipe 20 and is immersed in the fire extinguishing medium, the fire extinguishing medium can be sprayed out before the compressed gas when the fire extinguishing bottle 10 is inclined or topples over, and the fire extinguishing effect is ensured.

It will be appreciated that in this embodiment, the extinguishing medium is a liquid.

In addition, it should be explained that the floating member 30 floats on the fire extinguishing medium, that is, the floating member 30 receives buoyancy equal to the weight of the floating member 30, so that it can be determined that the floating member 30 always floats on the fire extinguishing medium regardless of whether the fire-extinguishing bottle 10 is tilted or toppled.

It can also be concluded that the float 30 is necessarily present partially immersed in the extinguishing medium. In this embodiment, the end of the connection channel 31 remote from the flexible spraying tube 20 is immersed in the fire extinguishing medium, so that when the fire-extinguishing bottle 10 is tilted or tipped, the end of the connection channel 31 remote from the flexible spraying tube 20 is still immersed in the fire extinguishing medium.

Wherein the first direction is the up-down direction in fig. 1. In addition, in practical application, since the ball 32 floats on the fire extinguishing medium and the end of the connection pipe 33 away from the flexible injection pipe 20 is always immersed in the fire extinguishing medium, the first direction in practical application is a vertical direction.

The connecting pipe 33 floats on the fire extinguishing medium through the ball 32, and one end of the connecting pipe 33 is connected with the flexible spraying pipe 20, and the other end is immersed in the fire extinguishing medium, so that the fire extinguishing medium is sprayed out before the compressed gas during fire extinguishing.

Further, the sphere 32 includes a solid portion 34 and a hollow portion 35 connected in sequence in the first direction, the solid portion 34 is immersed in the fire extinguishing medium, the connection pipe 33 penetrates the solid portion 34 and the hollow portion 35, one end of the connection pipe 33 protrudes from the hollow portion 35, and the flexible spraying pipe 20 is connected to one end of the connection pipe 33 protruding from the hollow portion 35.

It will be appreciated that the spherical body 32 floats on the fire extinguishing medium, and the spherical body 32 includes a solid portion 34 and a hollow portion 35, the solid portion 34 having a mass larger than that of the hollow portion 35, so that the solid portion 34 is always immersed in the fire extinguishing medium, and the end of the connection pipe 33 penetrating the solid portion 34 is always immersed in the fire extinguishing medium.

Specifically, the hollow portion 35 is opened with a sealed cavity 37, the central axis of the connecting pipe 33 passes through the center of the sphere 32, and the sealed cavity 37 is arranged around the connecting pipe 33.

In the above embodiment, the floating of the ball 32 on the fire extinguishing medium is realized by providing the hollow portion 35, but in other embodiments, the ball 32 may be provided as two materials, one is a high-density material capable of sinking into the fire extinguishing medium, and the other is a light material capable of floating on the fire extinguishing medium, the structures formed by the two materials are connected with each other and sequentially arranged along the first direction, and the connecting pipe 33 also penetrates through the two structures along the first direction.

In some embodiments, the ball 32 further includes a connection portion 36, the connection portion 36 is connected to a side of the hollow portion 35 away from the solid portion 34, the connection pipe 33 penetrates the solid portion 34, the hollow portion 35 and the connection portion 36, and the flexible injection pipe 20 is connected to the connection portion 36 so as to communicate with the connection pipe 33.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
