[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only. Example

[0018] See also Figure 1The utility model provides a controllable jet aerosol fire extinguishing device, the fire extinguishing device comprises a device housing 1, a nozzle 2 connected to the device housing 1 and extending out of the device housing 1, a sealed container 3 arranged inside the device housing 1 and connected to the nozzle 2, and a control valve 4 connected between the sealed container 3 and the nozzle 2, the sealed container 3 comprises a fire extinguishing agent container 31, an agent suction pipe 32 extending from the fire extinguishing agent container 31, and a medicine air bag 34 arranged in the fire extinguishing agent container 31, the control valve 4 comprises a deceleration valve 41 connected to the agent suction pipe 32, a solenoid valve 42 connected to the deceleration valve 41 and the other end of which is connected to the medicine air bag 34, and a control valve 43 connected to the nozzle 2, and the solenoid valve 42 is externally connected to a controller 44. It can be understood that the solenoid valve 42, the deceleration valve 41 and the control valve 4 are all existing technologies in the field, and will not be repeated here.
