[0042] Further, the outer shape of the elastic member 432 may be generally in a "soil" shape or a "shi" shape. Thus, when the user presses the key cap 43, the sealing ring 4323 of the key sleeve 41 can be inserted and kept abutting against the third sealing ring groove 412, ensuring the sealing effect of the explosion-proof flashlight 100. In some other embodiments, the cross section of each sealing ring 4323 may also be in an "eight" shape or an inverted "V" shape. In this way, when the user presses the key cap 43, not only is the abutting between the sealing ring 4323 and the third sealing ring groove 412 tighter, improving the sealing effect, but also the deformation of the elastic member 432 is greater, providing a greater elastic force and improving the user experience.

[0043] In some embodiments, please refer to Figures 1 to 5The explosion-proof flashlight 100 may also include a control component 50 and a battery component 60, which are arranged in the inner cavity of the lamp tube component 10.

The upper surface of the battery 62 abuts against the upper plate 611, and the side surface of the battery 62 abuts against the four side plates 612. The bracket 61 has a simple structure and can accommodate the battery 62 well.

[0048] When installing the control component 50 and the battery component 60, first place the control component 50 in the inner cavity, then fix the circuit board 51 with the first fastener 53, then place the bracket 61 in the inner cavity, and then place the battery 62 in the bracket 61. Finally, pass the second fastener 63 through the lamp head component 20 and the lower end of the bracket 61 to extend it into the accommodating cavity and abut against the bottom surface of the battery 62.

[0051] It is understandable that such a configuration enables the explosion-proof flashlight 100 to be charged using a charging stand, which is safe and reliable. In addition, the charging socket on the charging stand can use a USB TYPE C charging port. Based on the existing guide rail technology and electrical box technology, a universal charging bridge and an integrated charging cabinet can be used for charging through the charging stand, which is convenient for quickly charging multiple lamps at one time, and the charging environment is safe and tidy.

[0052] In some embodiments, see Figures 1 to 5 The bottom of the explosion-proof flashlight 100 may be provided with a magnetic attraction component, which not only facilitates the magnetic attraction charging of the explosion-proof flashlight 100, but also can be used to achieve magnetic attraction fixation, etc.

[0053] In some embodiments, see Figures 1 to 5 The explosion-proof flashlight 100 may also include a power detection module and an alarm module connected to each other. The power detection module is used to detect the remaining power of the battery 62. When the remaining power is lower than a preset value, the alarm module alarms to remind the user to charge in time. Further, the explosion-proof flashlight 100 may also include a display module 16 for displaying the remaining power or working status of the explosion-proof flashlight 100.

[0054] In specific applications, the explosion-proof structure can be a partitioned sealing structure, which encapsulates the control component 50, the battery component 60, etc. through potting glue, and each main module can be independently sealed to achieve explosion-proof, that is, the control component 50, the battery component 60, etc. are independently sealed, which on the one hand improves reliability, and on the other hand allows the control component 50 and the battery component 60 to be independently replaced and maintained.

[0055] In specific applications, the explosion-proof flashlight 100 may also include a detection module and a communication module. The detection module is used to detect the current state of the battery component 60, the control component 50 and / or the light source component 24. If the detection module detects that the battery component 60, the control component 50 and / or the light source component 24 are abnormal (excessive temperature or abnormal state such as electric sparks), a signal can be sent to the communication module; the communication module can be a ZIGBEE module, a Bluetooth module, etc., which can be connected to the gateway device. Through the setting of the communication module, the status information of the explosion-proof flashlight 100 can be obtained regularly. If the battery component 60, the control component 50 or the light source component 24 is abnormal, the maintenance manager can perform maintenance in time through the communication module and the detection module, and the maintenance of the explosion-proof flashlight 100 is convenient and efficient. The communication module can also receive control instructions, etc.

[0056] In a specific application, the explosion-proof flashlight 100 may further include an explosion-proof device disposed near the battery component 60, the control component 50 and / or the light source component 24. When the temperature inside the explosion-proof flashlight 100 is too high or electric sparks appear, the explosion-proof device controls the explosion-proof flashlight to stop working to prevent the explosion-proof flashlight 100 from exploding; or, when electric sparks appear inside the explosion-proof flashlight 100, the explosion-proof device automatically sprays a fire extinguishing agent and turns off the explosion-proof flashlight 100 to prevent the explosion of the explosion-proof flashlight 100 and endanger the safety of the user, and to avoid potential safety hazards in environments with explosive gases and dust such as petroleum, chemical, underground tunnels and medicine.

[0057] It is understandable that the explosion-proof flashlight of the utility model can be made of intrinsically safe explosion-proof type, and the energy of electric sparks or thermal effects that may be generated by the connecting wires inside the explosion-proof flashlight 100 and exposed to the explosive environment can be limited to a level that cannot produce ignition, that is, the generation of danger is directly controlled through circuit design. The shell of the lamp tube component 10 can be made of anti-static high-quality thermoplastic material injection molding, which is light in weight, has good corrosion resistance, is resistant to oil stains, and has good high and low temperature resistance; it can avoid the generation of static electricity, and also avoid the problem that the shell material is made of aluminum alloy and cannot be used in coal mine gas explosive environments due to its high aluminum content. The shell of the lamp head component 20 can be made of anti-static high-quality thermoplastic and high-quality transparent material double-color injection molding. The battery 62 can use a certified high-energy memory-free large-capacity rechargeable lithium battery, and an overcharge and over-discharge protection circuit can be provided inside the battery 62. And the driving circuit of the driving component can be designed in an intrinsically safe explosion-proof type, which is safe and reliable. At present, the mobile and portable explosion-proof lamps in the domestic market are often heavy, complicated in explosion-proof form and structure because of the explosion-proof form of flameproof + increased safety + intrinsic safety. The utility model explosion-proof flashlight 100 has a lamp head part 20 with adjustable angle, light weight, easy installation, easy operation, a magnetic suction function at the tail, a high product protection level, and is very convenient to use.
