Photoinduction training fire extinguisher

Abstract

The utility model discloses a photoinduction training fire extinguisher. The photoinduction training fire extinguisher comprises a fan; the normally-closed light sensation switch is electrically connected with a fan through a relay, a coil control connector of the relay is connected with a coil control switch, and the coil control switch is a normally-open switch; a flame object simulating flames is arranged at an air outlet of the fan. When the normally-closed light-sensitive switch is irradiated by corresponding light, the normally-closed light-sensitive switch is switched off, the relay is powered off, the fan stops working, and the flame stops floating, so that the process of extinguishing fire by aligning to the root of the flame can be simulated; as the normally-closed light sensation switch is irradiated by light to control the fan to be powered off to stop the flames from floating, the situation that the shell carries the flames to move due to blown airflow generated during training is avoided, and the training effect is improved.

Description

Technical Field

[0001] This utility model relates to a light-sensing training fire extinguisher, belonging to the technical field of fire extinguisher training equipment. Background Technology

[0002] In the past, when conducting fire extinguishing training with dry powder fire extinguishers, the dust generated by the extinguishers meant that the training had to be conducted outdoors and required ignition, making it impossible to conduct training indoors or at night.

[0003] The existing technology for indoor nighttime training using simulated fire extinguishers is described in Chinese Patent Publication No. CN116832386A. Although the fan speed is monitored by a speed measuring instrument, and the power to the fan is cut off to prevent the simulated red cloth from fluttering, thus achieving the effect of indoor nighttime training, the airflow during use causes the base on which the red cloth is installed to shift, resulting in poor training quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a light-sensing training fire extinguisher.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a light-sensitive training fire extinguisher, comprising:

[0007] Fan;

[0008] A normally closed photosensitive switch is electrically connected to a fan via a relay. The relay coil control connector is connected to a coil control switch, which is a normally open switch.

[0009] There are flame-like objects simulating flames at the air outlet of the fan.

[0010] The coil control switch is a remote control switch or a push-button switch.

[0011] The flame-shaped object was a red cloth ribbon.

[0012] It also includes a housing, a relay and a fan installed inside the housing, an air outlet is provided at the housing corresponding to the fan, and multiple flame objects are installed at the air outlet of the housing. When the fan is working and exhausting air, it blows the flame objects to float on the housing to simulate flames; the normally closed photosensitive switch is installed on the housing at the base of the flame objects.

[0013] The housing at the air outlet is also equipped with a red light and a smoke generator, which are connected in parallel with the fan power supply.

[0014] It also includes a fire extinguisher body, which is divided into an upper part and a lower part that is detachably connected to the upper part by a threaded connection. The upper part is used to house the battery power source, and the lower part is hollow and contains a removable counterweight.

[0015] The fire extinguisher body is equipped with a battery power supply, which is electrically connected to a light emitter via a push switch. The push switch is normally open and located at the push handle of the fire extinguisher body, while the light emitter is located at the nozzle of the fire extinguisher body.

[0016] The light emitter is a laser emitter, and the normally closed photosensitive switch is a laser decoder.

[0017] The beneficial effects of this utility model are as follows: when the normally closed photosensitive switch is irradiated by the corresponding light, the normally closed photosensitive switch opens, de-energizes the relay, stops the fan, and stops the flame from drifting, which can simulate the process of extinguishing a fire by aiming at the base of the flame; since the normally closed photosensitive switch is controlled by the light to de-energize the fan and stop the flame from drifting, the situation where the airflow during training causes the shell to move with the flame is avoided, thus improving the training effect.

Detailed Implementation

[0021] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0022] like Figures 1 to 2 As shown.

[0023] This application discloses a light-sensitive training fire extinguisher, comprising:

[0024] A normally closed photosensitive switch 1 is connected to a power adapter 11. The normally closed photosensitive switch 1 is electrically connected to a fan 3 via a relay 2. The fan 3 has a flame-like object 4 at its outlet. When the fan 3 is working, it blows the flame-like object 4 to make it drift, simulating the flame of ignition and combustion. The power adapter 11 can be a plug.

[0025] The coil control switch 21 of the relay 2 is a normally open switch. The coil control switch 21 can be a remote control switch or a self-contained push-button switch.

[0026] When the coil control switch 21 is a remote control switch, it can be closed remotely to energize the fan 3 via the relay 2. Compared to a push-button switch, this offers the advantage of remote control, eliminating the need for frequent manual triggering of the coil control switch 21 during multi-person training.

[0027] The flame object 4 is made of red cloth ribbons, which are cut into a triangular shape.

[0028] It also includes a housing 5, a relay 2 and a fan 3 installed inside the housing 5. An air outlet is provided at the housing 5 corresponding to the fan 3. Multiple flame-shaped objects 4 are installed at the air outlet of the housing 5. When the fan 3 is working and exhausting air, it blows the flame-shaped objects 4 to float on the housing 5 to simulate flames. The normally closed photosensitive switch 1 is installed on the housing 5 at the base of the flame-shaped objects 4.

[0029] The housing 5 at the air outlet is also equipped with a red light and a smoke generator, and is connected in parallel with the power supply of the fan 3 to simulate a red fire or smoke environment.

[0030] During realistic fire extinguishing training, personnel must aim the fire extinguisher at the base of the burning object 4 from an upwind position. A normally closed photosensitive switch 1 is located at the base of the burning object 4. When the normally closed photosensitive switch 1 is illuminated by the corresponding light 81, it opens, de-energizing the relay 2, stopping the fan 3, and halting the movement of the burning object 4. This effectively simulates the process of aiming the fire at the base of the burning object 4. Because the light 81 illuminates the normally closed photosensitive switch 1, controlling the fan 3 to de-energize and stop the movement of the burning object 4, the airflow generated during training prevents the casing 5 from shifting with the burning object 4, thus improving the training effectiveness.

[0031] It also includes a fire extinguisher body 6, which can be a real fire extinguisher available on the market. When modifying the cylinder part of the fire extinguisher body 6, the fire extinguisher body 6 is divided into an upper part 61 and a lower part 62 that is screwed onto the upper part 61. The upper part 61 is used to house the battery power supply 7, and the lower part 62 is hollow to house a counterweight 63 such as sand or water. When not training, the counterweight 63 is removed to reduce the weight of the fire extinguisher body 6 for daily carrying. When training is required, the counterweight 63 is filled with locally sourced materials to simulate the weight of the fire extinguisher body 6.

[0032] The fire extinguisher body 6 is equipped with a battery power supply 7, which is electrically connected to a light emitter 8 via a push switch 71. The push switch 71 is normally open and located at the push handle of the fire extinguisher body 6. The light emitter 8 is located at the nozzle of the fire extinguisher body 6. When the safety pin of the fire extinguisher body 6 is removed and the push handle of the fire extinguisher body 6 is pressed, the normally open push switch 71 closes, the battery power supply 7 supplies power to the light emitter 8, and the light emitter 8 emits a corresponding light 81 that shines on the normally closed photosensitive switch 1. The normally closed photosensitive switch 1 opens, de-energizing the relay 2, stopping the fan 3, and stopping the movement of the flame 4. This can simulate the process of extinguishing a fire by aiming at the base of the flame 4.

[0033] When the light emitter 8 is a laser emitter, the normally closed photosensitive switch 1 is a laser decoder. When the laser decoder receives the laser light 81, the laser decoder de-energizes the relay 2 and the fan 3 stops working.

[0034] When the light emitter 8 is an infrared emitter, the normally closed photosensitive switch 1 is an infrared photosensitive switch. When the infrared photosensitive switch receives infrared light 81, the infrared photosensitive switch de-energizes the relay 2, the fan 3 stops working, and the flame 4 stops drifting.
