Description

Technical Field

[0001] The present application relates to the technical field of flashlights, and in particular to a portable explosion-proof flashlight. Background Art

[0002] Flashlights are indispensable portable electronic lighting tools in daily life and professional work. They are composed of multiple precision components. The sturdy and durable shell serves as an external protective barrier, providing physical protection for the internal components. The high-performance battery serves as the energy core, continuously and stably outputting electricity. The intelligent control panel precisely regulates the current and lighting mode. The light board is the source of light, efficiently converting electrical energy into light beams. These components work together, allowing flashlights to play a key role in many scenarios such as home emergencies, outdoor adventures, and industrial maintenance. They greatly enhance people's ability to cope with dark environments, thereby improving the convenience of life.

[0003] With the development of flashlights, in order to meet the stringent requirements of flashlight protection performance in different usage environments, manufacturers have invested a lot of research and development efforts in the selection of shell materials. By using high-strength engineering plastics, aviation-grade aluminum alloys and other materials to make shells, the shells made of these materials have excellent mechanical strength and can withstand external force impacts such as falls from heights and violent collisions, as well as excellent explosion-proof performance, which improves the safety of flashlight use. By performing special process treatments on the shell, such as surface hardening and anodizing, its wear resistance and corrosion resistance are further enhanced, effectively extending the service life of the flashlight, allowing it to still work stably and reliably in complex and harsh environments.

[0004] Although modern flashlights have made significant progress in many aspects, they still face challenges in heat dissipation design. During the continuous operation of the flashlight, the internal batteries, light boards and other electronic components will generate a lot of heat due to the conversion of electrical energy. Most existing flashlights mainly rely on the heat dissipation holes opened on the surface of the shell to dissipate heat. This passive heat dissipation method can maintain the temperature balance inside the flashlight when used for a short time and at a low load. However, when the flashlight is in a long-term continuous working state, especially when running in high-brightness mode, the heat dissipation efficiency of the heat dissipation holes cannot meet the needs. A large amount of heat cannot be discharged in time and continues to accumulate inside the shell, causing the internal temperature of the flashlight to rise sharply. Excessive temperature will accelerate the aging of electronic components, reduce the charging and discharging efficiency and cycle life of the battery, affect the luminous efficiency and color rendering of the lamp beads, and may even cause circuit failures, causing the flashlight to fail to work normally, thereby affecting the service life of the flashlight. Summary of the Invention

[0005] The purpose of this application is to solve the problem raised in the above background technology that the existing flashlight relies on heat dissipation holes to dissipate heat and cannot meet the heat dissipation requirements of the flashlight in a long-term continuous working state, causing the flashlight to be unable to be used normally. This application provides a portable explosion-proof flashlight.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A portable explosion-proof flashlight comprises an explosion-proof shell, one end of the explosion-proof shell is threadedly connected to a lampshade, the end of the explosion-proof shell away from the lampshade is threadedly connected to a cover plate, a handle is fixed to the cover plate, a flashlight switch is mounted on the handle, a battery is mounted inside the explosion-proof shell, a control panel is mounted on the side of the battery, a light board is mounted on the side of the control panel, a plurality of lamp beads are mounted on the light board, the explosion-proof shell is detachably connected to the control panel and the light board, the flashlight switch, battery, control panel and light board are electrically connected to each other, and a heat dissipation structure and a spoiler structure are provided inside the explosion-proof shell.

[0007] By adopting the above technical solution, the flashlight has an explosion-proof shell with good explosion-proof capability, the battery provides power for the lamp board, the control board plays a control role, and the flashlight switch is used to turn on or off the flashlight. When in use, press the flashlight switch to power on the lamp board. After the lamp board is powered on, the lamp beads light up to provide lighting function. During use, the user turns on the heat dissipation structure, which can effectively dissipate heat from the flashlight, reducing the impact of heat accumulation on the electronic components of the flashlight, thereby reducing the impact on the normal use of the flashlight. At the same time, the heat dissipation structure will cause the spoiler structure to work during operation, and the spoiler structure can improve the internal heat exchange effect of the flashlight, thereby improving the heat dissipation effect of the heat dissipation structure and making the heat dissipation more sufficient.

[0008] Furthermore, the heat dissipation structure includes a drive motor fixed inside the explosion-proof casing, a drive shaft is fixed to the output end of the drive motor, an impeller is fixed on the drive shaft, an air outlet is opened on the surface of the lampshade, a start switch is installed on the handle, and the drive motor, battery, control panel and start switch are electrically connected to each other.

[0009] By adopting the above technical solution, when in use, the drive motor is turned on by pressing the start switch, and the impeller is rotated by the drive motor. The rotation of the impeller accelerates the air flow rate, allowing external air to enter the interior of the explosion-proof shell, and blows out the heat generated by the battery, light board and other structures inside the explosion-proof shell, thereby playing a role in heat dissipation, and can reduce the impact of the normal use of the flashlight caused by the excessive internal temperature due to long-term use.

[0010] Furthermore, a mounting groove is provided on the surface of the cover plate, and a dustproof net is fixed inside the mounting groove.

[0011] By adopting the above technical solution, when the impeller rotates to send external air into the explosion-proof housing, the dustproof net can effectively reduce the dust in the external air from entering the explosion-proof housing, reducing the impact of dust on the electronic components inside the flashlight.

[0012] Furthermore, the spoiler structure includes a rotating shaft installed inside the explosion-proof housing, a plurality of spoilers are fixed on the rotating shaft, and the spoilers are arc-shaped. A transmission assembly is provided between the rotating shaft and the drive shaft.

[0013] By adopting the above technical solution, the driving motor rotates, and the rotating shaft rotates under the action of the transmission component. When the rotating shaft rotates, it drives a number of arc-shaped spoilers to rotate. The rotating spoilers can stir the hot air originally close to the battery and the light panel, so that it mixes with the air in other areas and exchanges heat faster, thereby improving the heat dissipation effect.

[0014] Furthermore, the transmission assembly includes a transmission ring gear fixed to the inner wall of the explosion-proof shell, a transmission gear 1 is fixed on the drive shaft, a transmission gear 2 is arranged inside the transmission ring gear, the transmission gear 2 is fixedly connected to the rotating shaft, the transmission gear 2 is meshed with the transmission ring gear and the transmission gear 1, a connecting frame is rotatably connected to the drive shaft, and the connecting frame is rotatably connected to the transmission gear 2.

[0015] By adopting the above technical solution, when the driving motor drives the driving shaft to rotate, the driving shaft drives the transmission gear 1 to rotate, and when the transmission gear 1 rotates, it drives the transmission gear 2 to rotate on its own. At the same time, under the action of the transmission ring gear, the transmission gear 2 rotates around the transmission gear 1, so that the transmission gear 2 rotates on its own while rotating around the transmission gear 1, playing a transmission role, so that the rotating shaft can rotate.

[0016] Furthermore, a humidity sensor is fixed to the side of the cover plate, and the humidity sensor is electrically connected to the control board.

[0017] By adopting the above technical solution, the humidity sensor is used to monitor the humidity of the air entering the explosion-proof shell. When the humidity is too high, the drive motor is turned off, reducing the problem of the electronic components inside the flashlight being affected by the high humidity of the air entering the explosion-proof shell.

[0018] Furthermore, a buzzer is fixed on the explosion-proof housing, and the buzzer is electrically connected to the control board.

[0019] By adopting the above technical solution, when the humidity sensor detects that the humidity of the air entering the explosion-proof shell is high, the control board receives the signal sent by the humidity sensor, and then sends a control signal to the buzzer, causing the buzzer to work and make a sound, thereby reminding the user to turn off the drive motor.

[0020] Furthermore, a rotating rod is fixed on the driving shaft, a cleaning rod is fixed on one end of the rotating rod away from the driving shaft, a cleaning brush is fixed on the cleaning rod, and the cleaning brush is in contact with the humidity sensor.

[0021] By adopting the above technical solution, when the driving shaft rotates, the rotating rod is driven to rotate, so that the cleaning rod drives the cleaning brush to rotate, thereby cleaning the humidity sensor probe, reducing dust attached to the humidity sensor probe, and improving monitoring accuracy.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. In the present application, the driving motor is powered on and starts working by pressing the start switch. When the driving motor is working, it drives the driving shaft to rotate, and the rotation of the driving shaft drives the impeller to rotate. The rotation of the impeller can accelerate the air flow rate inside the explosion-proof shell, send external air into the explosion-proof shell, and send the heat generated by the battery and the lamp board inside the explosion-proof shell out through the air outlet, thereby achieving heat dissipation. By dissipating heat to the flashlight, the temperature inside the explosion-proof shell can be effectively reduced. During the long-term use of the flashlight, the problem of the normal use of the flashlight being affected by the heat generated by the battery and the lamp board can be reduced, thereby increasing the service life of the flashlight.

[0023] 2. In the process of the drive shaft driving the impeller to rotate to dissipate heat for the flashlight, the drive shaft cooperates with the transmission gear 1 and the transmission gear 2 to rotate the rotating shaft. The rotation of the rotating shaft drives the arc-shaped spoiler to rotate. The rotation of the spoiler can stir the hot air originally close to the battery and the lamp panel, so that the hot air originally close to the battery and the lamp panel can mix and exchange heat with the air in other areas faster, so that the heat is sent out more quickly, thereby improving the heat dissipation effect of the heat dissipation structure; at the same time, when the transmission gear 2 rotates, under the action of the transmission ring gear, the transmission gear 2 will also rotate around the transmission gear 1 while rotating, so that the rotating shaft rotates and makes a circular motion inside the explosion-proof shell, which can further improve the spoiler effect, and further make the hot air originally close to the battery and the lamp panel contact with the air entering the explosion-proof shell more quickly, further improving the heat exchange effect, and thereby further improving the heat dissipation effect of the heat dissipation structure.

[0024] 3. During use, when the drive motor is in working state, the humidity sensor starts working, and the humidity of the air entering the explosion-proof shell can be monitored through the humidity sensor. When the monitored air humidity is higher than the preset humidity range value, a signal is sent to the control board. After receiving the signal, the control board sends a control signal to the buzzer. After receiving the signal, the buzzer emits a buzzer, thereby reminding the operator that the current ambient air humidity is high and the drive motor needs to be turned off to reduce the external high-humidity air from entering the explosion-proof shell; 4. At the same time, when the driving shaft drives the impeller to rotate to dissipate heat to the flashlight, it can drive the rotating rod to rotate. When the rotating rod rotates, the cleaning rod at its end rotates accordingly. When the cleaning rod rotates, the cleaning brush rotates accordingly. The rotation of the cleaning brush can reduce the dust attached to the humidity sensor probe and improve the monitoring accuracy of the humidity sensor. BRIEF DESCRIPTION OF THE DRAWINGS

The drive motor 21, the battery 15, the control board 16, and the start switch 25 are electrically connected to each other.

[0032] Among them, a mounting groove is opened on the surface of the cover plate 12, and a dustproof net 24 is fixed inside the mounting groove. When the driving motor 21 drives the impeller 23 to rotate, the external air enters the explosion-proof shell 1 through the mounting groove. At this time, the dustproof net 24 can reduce the dust in the external air from entering the explosion-proof shell 1.

[0033] When the user uses the flashlight, after pressing the flashlight switch 14, press the start switch 25. By pressing the start switch 25, the drive motor 21 is powered on and starts working.

The spoiler pieces 32 are arc-shaped. The arc-shaped spoiler pieces 32 can make the air exchange more thorough. A transmission assembly 33 is provided between the rotating shaft 31 and the drive shaft 22. The transmission assembly 33 is used to transmit the rotation force of the drive shaft 22 to the rotating shaft 31, so that the rotating shaft 31 rotates.

[0035] Among them, the transmission assembly 33 includes a transmission ring gear 331 fixed to the inner wall of the explosion-proof shell 1, a transmission gear 1 332 is fixed on the drive shaft 22, a transmission gear 2 333 is arranged inside the transmission ring gear 331, and the transmission gear 2 333 is fixedly connected to the rotating shaft 31.

A connecting frame 334 is rotatably connected to the drive shaft 22, and the connecting frame 334 is rotatably connected to the transmission gear 2 333.

[0036] When the driving shaft 22 drives the impeller 23 to rotate to dissipate heat for the flashlight, it can drive the transmission gear 1 332 to rotate. The rotation of the transmission gear 1 332 causes the transmission gear 2 333 meshing with it to rotate. The rotation of the transmission gear 2 333 can drive the rotation shaft 31 to rotate. The rotation of the rotation shaft 31 drives the arc-shaped spoiler 32 to rotate. The rotation of the spoiler 32 can stir the hot air originally close to the battery 15 and the lamp board 17, so that the hot air originally close to the battery 15 and the lamp board 17 can mix with the air in other areas faster and exchange heat, so that the heat It is sent out more quickly, thereby improving the heat dissipation effect of the heat dissipation structure 2; at the same time, when the transmission gear 2 333 rotates, under the action of the transmission ring gear 331, the transmission gear 2 333 rotates while also rotating around the transmission gear 1 332, thereby causing the rotating shaft 31 to rotate and make a circular motion inside the explosion-proof shell 1, which can further improve the turbulence effect, and further make the hot air originally close to the battery 15 and the lamp board 17 contact with the air entering the explosion-proof shell 1 more quickly, further improving the heat exchange effect, and further improving the heat dissipation effect of the heat dissipation structure 2.

[0039] During use, when the drive motor 21 is in working condition, the humidity sensor 4 starts working. The humidity of the air entering the explosion-proof shell 1 can be monitored through the humidity sensor 4. When the air humidity is detected to be higher than the preset humidity range value, a signal is sent to the control board 16. After receiving the signal, the control board 16 sends a control signal to the buzzer 5. After receiving the signal, the buzzer 5 emits a buzzing sound, thereby reminding the operator that the current ambient air humidity is high and the drive motor 21 needs to be turned off to reduce the impact of the external high humidity air entering the explosion-proof shell 1, causing the electronic components of the flashlight to become damp and affect its normal use.

[0041] When the driving shaft 22 drives the impeller 23 to rotate to dissipate heat from the flashlight, it can drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, the cleaning rod 61 at its end follows the rotation. When the cleaning rod 61 rotates, the cleaning brush 62 follows the rotation. The rotation of the cleaning brush 62 can reduce the dust attached to the probe of the humidity sensor 4, thereby reducing the impact of dust adhesion on the monitoring accuracy of the humidity sensor 4.

[0042] Working principle: The flashlight has an explosion-proof shell 1 with good explosion-proof ability. The battery 15 provides power for the lamp board 17, and the control board 16 plays a control role. The flashlight switch 14 is used to turn the flashlight on or off. When in use, the user holds the handle 13 and presses the flashlight switch 14 to energize the lamp board 17. After the lamp board 17 is energized, the lamp beads will light up. During use, after pressing the flashlight switch 14, the start switch 25 is pressed. By pressing the start switch 25, the drive motor 21 is energized to start working. When the drive motor 21 is working, it drives the drive shaft 22 to rotate, and the rotation of the drive shaft 22 drives the impeller 23 to rotate. The rotation of the impeller 23 can accelerate the air flow rate inside the explosion-proof shell 1, and send the external air into the explosion-proof shell 1, and send the heat generated by the battery 15 and the lamp board 17 inside the explosion-proof shell 1 through the air outlet, thereby realizing heat dissipation, which can reduce heat accumulation, so that the flashlight can still maintain normal lighting in the continuous working state; At the same time, when the driving shaft 22 drives the impeller 23 to rotate to dissipate heat for the flashlight, it can drive the transmission gear 1 332 to rotate. The rotation of the transmission gear 1 332 causes the transmission gear 2 333 meshing with it to rotate. The rotation of the transmission gear 2 333 can drive the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the arc-shaped spoiler 32 to rotate. The rotation of the spoiler 32 can stir the hot air originally close to the battery 15 and the lamp board 17, so that the hot air originally close to the battery 15 and the lamp board 17 can mix and exchange heat with the air in other areas more quickly, so that the heat is sent out more quickly, thereby improving the heat dissipation effect of the heat dissipation structure 2. Moreover, when the transmission gear 2 333 rotates, under the action of the transmission ring gear 331, the transmission gear 2 333 will also rotate around the transmission gear 1 332 while rotating, so that the rotating shaft 31 rotates and makes a circular motion inside the explosion-proof housing 1, which can further improve the spoiler effect. During use, when the drive motor 21 is in working condition, the humidity sensor 4 starts working, and the humidity of the air entering the explosion-proof shell 1 can be monitored through the humidity sensor 4. When the air humidity is detected to be higher than the preset humidity range value, a signal is sent to the control board 16. After receiving the signal, the control board 16 sends a control signal to the buzzer 5. After receiving the signal, the buzzer 5 emits a buzzing sound, thereby reminding the operator that the current ambient air humidity is high and the drive motor 21 needs to be turned off, thereby reducing the external air with high humidity from entering the explosion-proof shell 1; at the same time, when the drive shaft 22 drives the impeller 23 to rotate to dissipate heat to the flashlight, it can drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, the cleaning rod 61 at its end follows the rotation. When the cleaning rod 61 rotates, the cleaning brush 62 follows the rotation. The rotation of the cleaning brush 62 can reduce the dust attached to the probe part of the humidity sensor 4, thereby improving the monitoring accuracy of the humidity sensor 4.
