[0020] As Figures 1 to 4 shown, the flashlight of the utility model that can detect harmful gases and give real-time warnings includes a lamp cover 1, a barrel head 2, a barrel body 3, and a rear cover 4 that are connected in sequence. An annular magnet I 5 is connected below the barrel head 2, and an annular magnet II 6 is connected above the barrel body 3. The annular magnet I 5 and the annular magnet II 6 are cooperatively adsorbed to fixedly connect the barrel head 2 and the barrel body 3; an air inlet hole 7 is provided outside the barrel head 2, and an LED lamp group 8 and a gas sensor 9 are provided inside. Fixed cards 10 are provided on both sides of the gas sensor 9; an indicator light 11, a sound hole 12, a button I 13, and a button II 14 are provided outside the barrel body 3. An equipment bin 15, a vibration device 16, and a battery bin 17 are provided inside from top to bottom. A core board 18 and a speaker 19 are provided in the equipment bin 15; a wire groove 20 is also provided between the inside of the barrel body and the outer shell.

[0021] The gas sensor 9 corresponds to the position of the air inlet hole 7, and the speaker 19 corresponds to the position of the sound hole 12.

[0022] The lamp cover 1 is connected to the barrel head 2 through a threaded structure, and the rear cover 4 is connected to the barrel body 3 through a threaded structure.

[0023] An anti-slip pattern 21 is provided in the middle part on the outside of the barrel body 3; a hanging ring 22 is provided on the outside of the rear cover 4, and a charging port 23 is provided at the middle position of the bottom of the rear cover 4.

[0024] The LED lamp group 8, the gas sensor 9, the indicator light 11, the button I 13, the button II 14, the vibration device 16, and the speaker 19 are all electrically connected to the core board 18 through an FFC flexible cable.

[0025] The core board 18 adopts a PCB board. The PCB board is provided with a main control module, a wireless communication module, a GPS positioning module, and a DC buck module. The wireless communication module, the GPS positioning module, and the DC buck module are electrically connected to the main control module.

[0026] The main control module adopts an STM32 single-chip microcomputer, and the wireless communication module adopts an AIR724UG board.

[0027] Specifically, the utility model realizes the fixed connection of the barrel head 2 and the barrel body 3 by setting the annular magnet I 5 and the annular magnet II 6 that are used in cooperation at the connection of the barrel head 2 and the barrel body 3. The two are fixedly connected by strong attraction, which not only ensures the connection stability of the barrel head 2 and the barrel body 3 but also enables quick disassembly and assembly, avoiding damage to the internal circuit caused by the traditional rotary installation method. Fixed cards 10 are provided on both sides of the gas sensor 9 inside the barrel head 2. Different types of sensors can be quickly replaced through the fixed cards 10, enabling the utility model to detect various types of gases and having a wider application range.

[0028] Specifically, the utility model provides the ability to detect and give early warnings of potential dangers in real time during confined space operations, and provides corresponding warning and help-seeking means under dangerous environmental conditions. The core board 18 uses a PCB board to integrate a main control module, a DC buck module, a GPS positioning module, and a wireless communication module. Among them, the main control module uses an STM32 single-chip microcomputer as the control core. The battery stably supplies power to all electrical components through the DC buck module. The wireless communication module uses an Air724UG board as the communication core. A wire groove 20 is provided between the inside of the cylinder body 3 and the outer shell. All input and output devices are connected to the core board 18 through an FFC flexible cable. The FFC flexible cable is routed through the wire groove 20. The FFC flexible cable ensures that it is not easily broken during disassembly and assembly to ensure the smoothness of the circuit. At the same time, the plug-in FFC flexible cable provides convenience for the replacement of various functional components.

[0029] Specifically, when operating in a confined space, the operator presses the button I13, and the LED light group 8 lights up to achieve the lighting function. An air inlet hole 7 is provided on the outer side of the cylinder head 2, and air enters the flashlight through the air inlet hole 7. When the gas sensor 9 detects that there are harmful gases in the air, the main control module controls the indicator light 11 to light up to warn the operator that there are harmful gases in the current environment. When the gas sensor 9 detects that the concentration of harmful gases in the air is too high, the main control module controls the vibration device 16 to generate vibration to remind the operator to quickly leave the current environment. When the operator perceives physical discomfort or other dangerous situations and presses the button II14, the main control module controls the speaker 19 to sound to send out a distress signal to remind other operators to be alert and carry out timely rescue. The GPS positioning module is used to lock the current position of the operator. When the positioning information does not change for a long time, the main control module controls the wireless communication module to send a distress signal to the mobile terminal outside the operation scene.

[0030] Specifically, anti-slip patterns 21 are provided at the middle position on the outer side of the cylinder body 3 to increase the friction between the device and the palm when the staff holds it. A hanging ring 22 is provided on the outer side of the rear cover 4 and can be used with a hanging rope to prevent the device from being damaged due to slipping or other reasons. The charging port 23 at the bottom of the rear cover 4 is matched with a corresponding plug to prevent water from entering and damaging the device.
