As shown in fig. 1, an embodiment of the present invention provides a fire suppression apparatus 10 including a fire suppression container 12, a handle member 14, and a sealing member 16.

The fire extinguishing container 10 is used for storing the liquid fire extinguishing agent 20 and the compressed gas 30, and one end of the fire extinguishing container 10 is provided with a communication port 122 communicated with the interior thereof.

The handle member 14 is disposed on the side of the fire extinguishing container 10 adjacent to the communication port 122.

The sealing member 16 is in communication with the communication port 122, the sealing member 16 includes a conducting state and a blocking state, and when the sealing member 16 is in the conducting state, the communication port 122 is in communication with the outside through the sealing member 16; when the seal 16 is in the off state, the seal 16 seals the communication port 122.

By providing the fire extinguishing apparatus as described above, initially, the sealing member 16 is in the cut-off state, the liquid fire extinguishing agent 20 and the compressed gas 30 are stored in the fire extinguishing container 10, and in the event of a fire, a fire extinguishing person can hold the fire extinguishing apparatus by the handle member 14 and face the sealing member 16 to the position of fire, and then change the state of the sealing member 16 from the cut-off state to the conduction state, the communication port 122 is connected to the outside through the sealing member 16, and the sealing member 16 faces the position of fire, so that the liquid fire extinguishing agent 20 in the fire extinguishing container 10 can be sprayed to the position of fire, and the fire extinguishing process can be achieved. Thus, the liquid fire extinguishing agent 20 in the fire extinguishing container 10 is directly pushed to be sprayed out through the compressed gas 30, and more valve groups and pipelines are not needed to be arranged, so that the fire can be extinguished, and the safety is improved.

In some embodiments, the liquid fire extinguishing agent 20 is perfluorohexanone, which is a highly effective, non-toxic, clean, and environmentally friendly fire extinguishing agent that can extinguish A, B, C, E, F-class fires, is safe for use in manned locations, and has no residue after fire extinguishing.

In some embodiments, the compressed gas 30 is nitrogen. It should be noted that although the amount of nitrogen gas is required to ensure that a large amount of the liquid fire extinguishing agent 20 is sprayed, and it is required to ensure that the nitrogen gas can be sprayed at the end, the fire can be extinguished by the nitrogen gas spraying, and the fire extinguishing capability is further improved.

In some embodiments, the fire extinguishing container 10 has a receiving chamber for storing the liquid fire extinguishing agent 20 and the compressed gas 30, and the communication port 122 is in communication with the receiving chamber. Specifically, in the present embodiment, the fire extinguishing container 10 is a rectangular box. Of course, in other embodiments, the fire suppression container 10 may be other shapes, such as a cylinder.

Regardless of the shape of the fire extinguishing container 10, it is necessary to ensure that the opening of the communication port 122 is spaced apart from the position where the handle member 14 is connected, so that the fire extinguishing person can easily move the sealing member 16 toward the firing position when lifting up the fire extinguishing container 10 by hand.

Furthermore, the fire suppression container 10 will not generally be spherical, i.e., the fire suppression container 10 will have at least a plurality of surfaces.

In some embodiments, the fire extinguishing container 10 includes an inner shell having the receiving cavity and an outer shell covering the outer surface of the inner shell, the handle 14 is connected to the outer shell, the inner shell has a first through hole communicating with the receiving cavity, the outer shell has a second through hole communicating with the first through hole, and the first through hole and the second through hole are communicated together to form the communication opening 122.

In practical applications, the inner shell is made of stainless steel, while the outer shell is made of hard plastic. It is believed that the inner shell functions to contain the high pressure liquid fire suppressant 20 and compressed gas 30, while the outer shell further enhances the protective effect, while also providing an aesthetically pleasing appearance to the fire suppression container 10 and facilitating attachment to the handle member 14.

In some embodiments, the communication opening 122 opens at an edge of one end of the fire suppression container 10, and the handle member 14 is disposed on a side away from the communication opening 122. As will be understood from fig. 1, the communication opening 122 is opened at the bottom of the fire extinguishing container 10, and the handle member 14 is provided on the top surface of the fire extinguishing container 10. Therefore, the pressure of the sprayed liquid fire extinguishing agent 20 comprises the pressure provided by the compressed gas 30 and the gravity of the liquid fire extinguishing agent 20, so that the amount of the compressed gas 30 can be reduced to a certain extent under the condition of ensuring the spraying pressure of the liquid fire extinguishing agent 20, the pressure of the fire extinguishing container 10 is reduced, the situation of over-high pressure explosion is avoided, and the use safety of the fire extinguishing device is improved.

It should be noted that the communication port 122 may be opened at the bottom of the fire extinguishing container 10, at the side of the fire extinguishing container 10, or at the side of the fire extinguishing container 10, as shown, as long as the pressure for spraying the liquid fire extinguishing agent 20 by its own weight is ensured. Of course, a bottom of the side is preferred to facilitate handling by fire fighters.

Meanwhile, it is unambiguously determined that the communication hole is located at the bottom when the fire extinguishing container 10 is normally placed, and the density of the liquid fire extinguishing agent 20 is greater than that of the compressed gas 30, so that the liquid fire extinguishing agent 20 is located below the compressed gas 30 after the liquid fire extinguishing agent 20 and the compressed gas 30 are charged into the fire extinguishing container 10, i.e., it is ensured that the communication hole 122 and the sealing member 16 are filled with the liquid fire extinguishing agent 20 when the sealing member 16 is in the cut-off state, so that the liquid fire extinguishing agent 20 is sprayed out in time when the sealing member 16 is brought into the conduction state.

In some embodiments, the handle member 14 is also made of a rigid material to facilitate attachment to the housing of the fire suppression container 10.

In some embodiments, the fire suppression apparatus further includes a flexible pad disposed on the handle member 14 to facilitate gripping by a fire suppressant person. Specifically, the flexible pad is a rubber mat that covers at least a portion of the handle member 14.

In some embodiments, the sealing member 16 is a control valve, one end of which is in communication with the communication port 122, and which is held by a fire fighter in the event of a fire by the handle member 14 so that the other end of the control valve is directed toward the firing position. Specifically, the control valve is a solenoid valve.

In some embodiments, the fire suppression apparatus further includes a controller electrically connected to the seal 16 for controlling the seal 16 to switch between the on state and the off state. Further, the fire extinguishing apparatus further comprises a control button 18, the control button 18 is disposed on the handle member 14, and the control button 18 is electrically connected to the controller for sending an on-off signal to the controller, and the controller controls the sealing member 16 to switch between the on-state and the off-state according to the on-off signal.

For example, initially, the seal 16 is in the off state, the fire fighter presses the control button 18, the control button 18 sends an on signal to the controller, and the controller controls the seal 16 to transition from the off state to the on state; when the seal 16 is in the on state, the fire extinguisher person presses the control button 18, and the control button 18 sends an off signal to the controller, which controls the seal 16 to switch from the on state to the off state.

It should be noted that the control button 18 and the controller are well known to those skilled in the art, and will not be described herein.

Meanwhile, the control button 18 is provided on the handle member 14, but it is necessary to ensure that the fire-fighting person does not touch the control button 18 by mistake when the fire-fighting device is used for fire-fighting.

In some embodiments, the fire suppression apparatus further includes a false touch prevention cover rotatably coupled to the handle member 14 for covering over the control button 18 to prevent false touches.

In some embodiments, the compressed gas is nitrogen. It should be noted that although the amount of nitrogen gas is required to ensure that a large amount of liquid fire extinguishing agent is sprayed, and it is required to ensure that the nitrogen gas can be sprayed at the end, the nitrogen gas can be sprayed to extinguish fire, thereby further improving the fire extinguishing ability.

In some embodiments, the fire extinguishing container includes an inner shell and an outer shell, the inner shell has the above-mentioned containing cavity, the outer shell covers the outer surface of the inner shell, the handle member is connected to the outer shell, the inner shell is provided with a first through hole communicated with the containing cavity, the outer shell is provided with a second through hole communicated with the first through hole, and the first through hole and the second through hole are communicated together to form the above-mentioned communicating opening.
