Referring to fig. 1 and 2, in a specific application, the fire extinguishing chamber 10 is provided with a fire extinguishing agent storage chamber 11, in which a large amount of fire extinguishing agent of class F is stored, although other types of fire extinguishing agents may be used, which are not limited herein; optionally, in this embodiment, for example, the fire extinguishing agent releasing mechanism 30 is installed in the fire extinguishing chamber 10, and a nozzle 12 communicating with the fire extinguishing agent storing chamber 11 is further provided on a side surface of the fire extinguishing chamber 10; meanwhile, in this embodiment, different kinds of gas generating agents are disposed in the fire extinguishing agent releasing mechanism 30, wherein a gas delivery end of the fire extinguishing agent releasing mechanism 30 is communicated with the fire extinguishing agent storage chamber 11, and when the fire extinguishing chamber 10 is fixed on the fire extinguishing panel 40, the gas generating agents in the fire extinguishing agent releasing mechanism 30 are isolated from each other; thus, in the absence of a fire, the entire fire extinguishing device is not operated.
When the panel release mechanism 20 detects a fire, the panel release mechanism 20 releases the fire extinguishing chamber 10 from the fire extinguishing panel 40, so that the gas generating agents in the fire extinguishing agent release mechanism 30 are mixed with each other under the action of gravity to generate gas to be introduced into the fire extinguishing agent storage chamber 11, and the fire extinguishing agent in the fire extinguishing agent storage chamber 11 is sprayed out from the nozzle 12 under the action of pressure, so as to achieve the fire extinguishing effect; of course, in the present embodiment, the nozzles 12 may be provided in plural numbers, and the specific number is not limited thereto.

Referring to fig. 1 and 2, the following specific structures of the respective mechanisms in the fire extinguishing apparatus are provided:
first, in the present embodiment, one of the structures of the fire extinguishing agent discharging mechanism 30 is provided:
referring to fig. 2, in this embodiment, the fire suppressant release mechanism 30 may include, but is not limited to: a gas generating agent chamber 31 and a partition plate 32, wherein the partition plate 32 is arranged in the gas generating agent chamber 31 and divides the gas generating agent chamber 31 into a first gas generating chamber 31a and a second gas generating chamber 31b; in specific application, a first gas generating agent is disposed in the first gas generating chamber 31a, and a second gas generating agent is disposed in the second gas generating chamber 31b, wherein the first gas generating chamber 31a is communicated with the fire extinguishing agent storage chamber 11, the length of the partition plate 32 is smaller than that of the gas generating agent chamber 31, and when the fire extinguishing chamber 10 is fixed on the fire extinguishing panel 40, the gas generating agent chamber 31 is in a vertical state.
Based on the above description, the fire extinguishing agent discharging mechanism 30 operates on the following principle: when the kitchen equipment does not have a fire disaster, the first gas generating cavity 31a and the second gas generating cavity 31b are in a vertical state, and at the moment, the gas generating agents in the first gas generating cavity and the second gas generating cavity are both positioned at the bottoms of the respective cavities, so that the gas generating agents in the first gas generating cavity and the second gas generating cavity are in an isolated state and do not generate chemical reaction; and once the panel release mechanism 20 detects a fire of kitchen equipment, the fire extinguishing chamber 10 is released from the fire extinguishing panel 40, and at this time, the first gas generating chamber 31a and the second gas generating chamber 31b are inverted (see fig. 3), so that the gas generating agents in the two chambers are mixed from the gap of the partition plate 32, and thus a chemical reaction occurs to generate a large amount of gas; finally, the generated gas is introduced into the fire extinguishing agent storage chamber 11 to finally spray the fire extinguishing agent from the nozzle 12.
Referring to fig. 1, another structure for providing the fire extinguishing agent discharging mechanism 30 is as follows:
in this embodiment, the fire extinguishing agent releasing mechanism 30 may include, for example and without limitation: a first gas generating cavity 31a and a second gas generating cavity 31b, wherein the second gas generating cavity 31b is arranged in the first gas generating cavity 31a, the first gas generating cavity 31a is communicated with the fire extinguishing agent storage cavity 11, and an opening is arranged on the side surface of the second gas generating cavity 31b facing the panel release mechanism 20; similarly, in this embodiment, a first gas generating agent is also disposed in the first gas generating chamber 31a, a second gas generating agent is disposed in the second gas generating chamber 31b, and when the fire extinguishing chamber 10 is fixed on the fire extinguishing panel 40, the first gas generating chamber 31a and the second gas generating chamber 31b are in a vertical state; thus, with this structure, the fire extinguishing agent discharging mechanism 30 operates on the principle that: under normal conditions, the first gas producing cavity 31a and the second gas producing cavity 31b are in vertical states, gas producing agents in the first gas producing cavity 31a and the second gas producing cavity 31b are respectively arranged at the bottoms of the cavities, and once the panel release mechanism 20 detects that kitchen equipment is in fire, the fire extinguishing cavity is released from the fire extinguishing panel, so that under the action of gravity, the first gas producing cavity 31a and the second gas producing cavity 31b are inverted, and the gas producing agents in the second gas producing cavity 31b enter the first gas producing cavity 31a through the opening and are mixed with the gas producing agents in the first gas producing cavity 31a, and chemical reactions are carried out, so that a large amount of gas is generated and is introduced into the fire extinguishing agent storage cavity 11; thus, a large amount of gas is generated to drive the fire extinguishing agent to be ejected from the nozzle 12, thereby achieving the effect of extinguishing a fire.
Alternatively, in the present embodiment, the gas generating agent in the first gas generating chamber 31a may be exemplified by, but not limited to, aqueous sodium bicarbonate solution, and the gas generating agent in the second gas generating chamber 31b may be exemplified by, but not limited to, aqueous acetic acid solution.
Further, in this embodiment, in order to prevent the evaporation of the gas generating agent in the second gas generating chamber 31b, a flip cover 31c is further disposed at the opening of the second gas generating chamber 31b, as shown in fig. 1; through the design, the reliability of the device can be improved.
In this embodiment, for example, the first gas generating chamber 31a communicates with the fire extinguishing agent storing chamber 11 through a hose 33 to realize gas delivery; meanwhile, the hose 33 is further provided with a one-way valve, so that the fire extinguishing agent can be prevented from flowing back into the first gas generating cavity 31a, and the gas generating agent in the first gas generating cavity 31a can be prevented from being evaporated completely; thereby, the reliability of use is further improved.
Referring to fig. 1 and 2, one specific configuration of the panel release mechanism 20 is provided as follows:
in this embodiment, the panel release mechanism 20 may include, but is not limited to: a temperature sensing element 21 and a hook ear 22, wherein the temperature sensing element 21 melts or breaks at a high temperature when the temperature exceeds a threshold value; based on such characteristics of the temperature sensing element 21, the following structure is provided in the concrete implementation: the temperature sensing element 21 is fixed on the side surface of the fire extinguishing cavity 10 through the mounting seat 23, the hook lug 22 is mounted on the end surface of the fire extinguishing panel 40 facing the fire extinguishing cavity 10, and when the hook lug 22 is hooked on the temperature sensing element 21, the fire extinguishing cavity 10 is fixed on the fire extinguishing panel 40.
The principle of operation of the panel release mechanism 20 is: under normal conditions, the hook ears 22 are hooked on the temperature sensing element 21, so that the fire extinguishing cavity 10 can be fixed on the fire extinguishing panel 40; when the kitchen equipment is in fire, high temperature is generated, the temperature sensing element 21 is melted or broken, at the moment, the hook lug 22 loses the hook point, the fixing effect on the fire extinguishing cavity 10 is lost, and the fire extinguishing cavity 10 can be put down under the action of gravity after losing the fixing force, so that the first gas producing cavity 31a and the second gas producing cavity 31b are inverted, and the gas producing agents in the first gas producing cavity 31a and the second gas producing cavity are mixed to generate chemical reaction, so that a large amount of gas is finally generated and introduced into the fire extinguishing agent storage cavity 11.
Further, in this embodiment, in order to ensure the reliability of the operation of the panel release mechanism 20, a spring 24 is further provided, as shown in fig. 1 and 2, the example spring 24 is mounted on the end face of the fire extinguishing panel 40 facing the fire extinguishing chamber 10, and when the hook ear 22 is hooked on the temperature sensing element 21, the spring 24 is compressed between the fire extinguishing panel 40 and the fire extinguishing chamber 10; thus, by utilizing the elastic force of the spring 24, the initial power for overturning the fire extinguishing cavity 10 can be increased, so that not only the triggering reliability can be improved, but also the triggering response speed can be improved.
In the present embodiment, the temperature sensing element 21 may be, for example, but not limited to, a temperature sensing glass bulb having a nominal operating temperature of 57 degrees celsius or other temperature.
In addition, in order to limit the angle of the fire extinguishing chamber 10 being turned down, the present embodiment further provides a limiting rope 50 between the fire extinguishing chamber 10 and the fire extinguishing panel 40; as shown in fig. 1, the fire extinguishing chamber 10 can be limited, and the fire extinguishing chamber 10 is prevented from being overturned downwards excessively; meanwhile, in this embodiment, for example, one end of the fire extinguishing chamber 10 is rotatably connected to the fire extinguishing panel 40 through a rotating shaft, and the other end of the fire extinguishing chamber 10 is vertically fixed to the fire extinguishing panel 40 through the panel release mechanism 20, so that the fire extinguishing chamber 10 can be reused conveniently, thereby reducing the use cost.
Therefore, the whole working process of the fire extinguishing device is as follows:
normally, the fire extinguishing chamber 10 is fixed in the closed position due to the obstruction of the temperature-sensitive glass bubbles; the gas generating chamber 30 is maintained in a vertical state, and the sodium bicarbonate aqueous solution and the acetic acid aqueous solution are completely separated from each other, and chemical reaction does not occur.
When kitchen equipment fires, the temperature near the top of a kitchen range rises rapidly, reaches the nominal action temperature of the temperature sensing glass bubble, and the temperature sensing glass bubble is broken immediately, loses the fixed effect on the fire extinguishing cavity 10, under the action of the spring 24 and self gravity, the fire extinguishing cavity 10 turns down along the axis, meanwhile, the limit rope 50 controls the turning angle, at this moment, the gas generating agent cavity 30 is turned upside down, under the action of gravity, sodium bicarbonate aqueous solution and acetic acid aqueous solution are mixed, a large amount of carbon dioxide gas is generated immediately, and the gas enters into the fire extinguishing agent storage cavity 11 through the hose 33 and the one-way valve to push F-type fire extinguishing agent to be sprayed out through the nozzle 12, so that fire extinguishing is realized.
In one possible design, referring to fig. 4, the second aspect of the present embodiment is further optimized based on the first aspect of the embodiment, where one or more of a mechanical emergency device, an electrical release device, an electrical feedback device, and an electrical alarm device are added to the device.
In this embodiment, the electric release device and the electric feedback device are both electrically connected to the fire alarm controller, so that when kitchen equipment catches fire, the fire automatic alarm system can quickly respond, and the fire alarm controller sends a start signal to the electric release device to start the fire extinguishing device, thereby realizing fire extinguishing; and when the kitchen equipment fire extinguishing device is started successfully, the electric feedback device reports a feedback signal back to the fire alarm controller to confirm that the device is started successfully.
If on-site personnel find that kitchen equipment fires but the fire extinguishing device is not started, the mechanical emergency device can be directly operated, the kitchen equipment fire extinguishing device is manually started to extinguish fire, and at the moment, the electric feedback device sends an alarm signal to the fire alarm controller to trigger the fire automatic alarm system to draw attention of personnel.
Finally, it should be noted that: the foregoing description is only of the preferred embodiments of the invention and is not intended to limit the scope of the invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
