The operation of the fire extinguishing nozzle is the same as that of a real fire extinguisher, so that a user can really simulate the process of opening the fire extinguisher to carry out fire extinguishing simulation exercise, and the fire extinguishing nozzle is safe, reliable and low in cost. In this embodiment, the signal transmitting module 121 and the switch triggering device 17 are electrically connected to the control circuit board, and the operating states of the signal transmitting module 121 and the switch triggering device 17 are controlled by the control circuit board in a unified manner, so as to achieve automatic start and stop according to requirements.

In addition, the light source device 55 is disposed below the first mist outlet passage 513, and the light source device 55 can emit light source irradiating toward the first mist outlet passage 513, so that the water mist discharged from the first mist outlet passage 513 interferes with and diffracts the light source emitted by the light source device 55, thereby forming more realistic simulated flames above the first mist outlet passage 513. The light source device 55 and the liquid storage container 52 are arranged independently, so that the contact between the water mist in the liquid storage container 52 and the lamp of the light source device 55 is isolated, and the service life is longer; in addition, the light source device 55 can generate a certain amount of heat during operation, thereby ensuring the dryness of the space in the storage chamber 512.

For example, the mist outlet of the second mist outlet channel 523 may be arranged to abut against the mist inlet of the first mist outlet channel 513; alternatively, as shown in fig. 7, the second mist outlet passage 523 may extend into the first mist outlet passage 513; or other arrangement modes which can effectively prevent the water mist from being dispersed and not concentrated are adopted. The specific shape of the second mist outlet channel 523 is not limited as long as the second mist outlet channel 523 can uniformly and intensively discharge the mist in the liquid storage container 52.

In fig. 12 to 13, terms of respective circuit devices are explained as follows: in fig. 12, "FengJi" represents a blower, i.e., the aforementioned blower device; in FIG. 13, "JDQ" represents a relay of type JQC-3FF-005-1ZS, and "GDOHQ" represents a photocoupler of type PC 817B; in fig. 14, "WuHuaQi" represents a nebulizer, i.e., the aforementioned nebulizing device.

Referring to fig. 10, in the above embodiment, the circuit control system 6 further includes a power module 7, and the power module 7 is electrically connected to the first control module 61. The power supply required by the flame simulation equipment during working is introduced into the power supply module 7 through a power line, and the required electric quantity is provided for each electric device and each control module through the power supply module 7.

As shown in fig. 7 and 8, the plurality of sets of laser sensor arrays are disposed on 51. As shown in fig. 15, during actual use, the on or off of each set of laser sensors 511 is controlled by the first control module 61. For example, in the application scenario of simulating the practice of fire fighting, a user can hold the fire extinguisher with his hand to align the nozzle (the position of the nozzle is provided with the laser emitting module) with the laser sensor 511 on the housing 51, when he presses the light emitting button, the laser signal emitted by the fire extinguisher is captured by the laser sensor 511 on the housing 51, and the laser sensor 511 then sends a feedback signal to the first control module 61, so that the first control module 61 gradually stops working by controlling the atomizing device, the blowing device, the light source device, and the like, thereby simulating the process of fire fighting.

In addition, in the above embodiment, the simulated fire extinguishing system includes a plurality of fire extinguishers, a signal transmitting module is correspondingly arranged at the nozzle position of each fire extinguisher, and different signal transmitting modules can transmit laser signals of different frequency bands. The laser frequency bands emitted by the laser transmitters arranged on the fire extinguishers are different and can be identified by different laser sensors on the shell of the flame simulation equipment. For example, if the current flame simulation device simulates a flame generated by alcohol ignition, the first control module 61 may control the laser sensor corresponding to the frequency band of the laser emitted by the laser emitter on the fire extinguisher adapted to the fire extinguishing scene to be turned on, and turn off the other laser sensors. For example, the fire extinguisher of looks adaptation is the dry powder fire extinguisher, and when the user took up the dry powder fire extinguisher and aimed at signal induction module 511 and operate, the corresponding laser sensor on signal induction module 511 just can catch the sensing signal, and then adjusts the intensity of a fire through first control module 61. If other fire extinguishers (which are not suitable for the alcohol application scenario) are aligned with the signal sensing module for operation, the first control module 511 will not respond to the relevant operation, i.e., the size of the simulated flame will not be adjusted, because the other fire extinguishers cannot emit laser light that can be captured by the currently-turned-on laser sensing module. The other situations of combustible ignition and the selection of the fire extinguisher are similar to the above-mentioned modes, and the description is omitted here. In short, whether the first induction signal is responded or not is determined by comparing the type of the corresponding induction signal under the current simulated flame type with the first induction signal, and then the fire extinguishing function is realized.

The application provides a shower nozzle, fire extinguisher and simulation fire extinguishing systems can be used to fields such as science and technology exhibition room, education popularization, wisdom city, and the user can know the principle and the application method of different grade type fire extinguishers through the simulation fire extinguishing systems that this application provided, popularizes fire control knowledge.
