[0037] See also Figures 1 to 4 The present invention provides a multifunctional flashlight 10, which includes: a lamp body 100, an LED lamp board 200, a laser head 300, a power supply 400, a charging board 500 and a control module 600.

[0038] See also Figure 2 The lamp body 100 is provided with a main chamber 11 and sub-chambers 12 and a light-transmitting chamber 13 located on both sides of the main chamber 11;

[0039] The LED light board 200 and the laser head 300 are located in the light-transmitting cavity 13 , the charging board 500 is located in the sub-cavity 12 , and the power supply 400 and the control module 600 are located in the main cavity 11 .

[0040] See also Figure 1 , Figure 2 and Figure 5The control module 600 includes a start button 610, a shift wheel 620, a magnet 630, a circuit board 640 and a reset spring 650. The outer wall of the lamp body 100 is provided with an arc limit groove 110 and a groove 120, the shift wheel 620 is rotatably arranged in the groove 120, the magnet 630 is arranged on the shift wheel 620, and the magnet 630 is located in the arc limit groove 110, a plurality of magnetic switches 641 are arranged on the circuit board 640, and the magnetic switches 641 are located on the displacement track of the magnet 630, the start button 610 passes through the shift wheel 620, the reset spring 650 is located between the start button 610 and the shift wheel 620, and the circuit board 640 is provided with a start switch 642 matching the start button 610.

[0041] A wiring hole communicating with the sub-chamber 12 and the light-transmitting cavity 13 is provided in the main chamber 11 , and the LED light board 200 , the laser head 300 , and the power supply 400 are all electrically connected to the circuit board 640 .

[0042] When using the multifunctional flashlight 10 , it is necessary to press the start button 610 first. After the start button 610 is triggered, the LED light board 200 or the laser head 300 is lit to achieve lighting.

[0043] Rotating the shift wheel 620 can make the magnet 630 slide along the arc limit groove 110, so that the magnet 630 moves above one of the magnetic switches 641 and triggers the magnetic switch 641. The circuit board 640 lights up the LED light board 200 or the laser head 300 according to the triggered magnetic switch 641, thereby switching the lighting mode.

[0044] See also Figure 2 , Figure 3 and Figure 6 Preferably, the control module 600 further includes a stop bead 661 and a stop spring 662. The shift wheel 620 is provided with a plurality of recesses 621 matching the stop bead 661. The stop bead 661 is located between the shift wheel 620 and the groove 120. The stop spring 662 is used to push the stop bead 661 so that the stop bead 661 fits the shift wheel 620. The distribution positions of the recesses 621 correspond to the distribution positions of the magnetic switches 641. Whenever the stop bead 661 sinks into the recess 621, the magnet 630 is just located above one of the magnetic switches 641. The stop bead 661, the stop spring 662 and the recess 621 cooperate to provide positioning for the shift wheel 620, so that the user can shift gears accurately.

[0045] See also Figure 4In one embodiment, a pointer 624 is provided on the outer wall of the shift wheel 620, a gear mark 160 is provided on the outer wall of the lamp body 100, and the pointer 624 faces the gear mark 160. The user can turn the shift wheel 620 according to the needs, and the pointer 624 is turned to the target gear mark 160, so that the user can intuitively distinguish the current lighting mode. Preferably, the outer wall of the lamp body 100 is provided with anti-slip grooves 130.

[0046] The above multifunctional flashlight 10 has the following advantages:

[0047] 1. The laser head 300 and the LED light panel 200 are configured to enable the flashlight to have multiple lighting modes, thereby reducing the load on construction workers. The lighting modes can be switched by rotating the shift wheel 620 to meet the lighting needs in different scenes and provide convenient lighting for the construction process;

[0048] 2. The electronic components inside the lamp body 100 are separated by the main chamber 11, the sub-chamber 12 and the light-transmitting cavity 13, which increases the difficulty of external water vapor adhering to the circuit board 640 and the power supply 400, avoiding them from malfunctioning due to moisture, thereby increasing the service life of the flashlight.

[0049] See also Figure 1 In one embodiment, a lens 141, a reflective cup 142 and a waterproof ring 143 are provided in the light-transmitting cavity 13, and a rubber plug 144 is provided on the sub-cavity 12. The waterproof ring 143 and the rubber plug 144 are used to seal the light-transmitting cavity 13 and the sub-cavity 12 to prevent external foreign matter and water vapor from entering, and are used to improve the sealing performance of the lamp body 100.

[0050] It should be noted that the multifunctional flashlight 10 is mostly used in outdoor construction sites such as power grids and railways. These sites are all places with complex outdoor environments. Especially when constructing on rainy days, water vapor in the construction environment can easily penetrate into the lamp body 100 through the gaps between the components, causing the circuit board 640 to get damp and cause failure. On the other hand, the multifunctional flashlight 10 requires long-term lighting to meet the needs of emergency maintenance, and the output power of the LED lamp board 200 is large, which means that the LED lamp board 200 and the power supply 400 will generate obvious heat during use, and the pressure in the main chamber 11 will increase. The increased temperature and pressure can easily cause failure of the circuit board 640, thereby reducing the service life of the multifunctional flashlight 10.

[0051] See also Figure 7 and Figure 8To solve the above problem, the start button 610 includes an extension rod 611, a flange 612 and a contact cap 613. The contact cap 613 is threadedly connected to the extension rod 611. The extension rod 611, the flange 612 and the contact cap 613 together form a supporting structure with wide sides and a narrow middle. The extension rod 611 passes through the shift wheel 620 and extends into the main chamber 11. The flange 612 is located outside the shift wheel 620. The return spring 650 is against the flange 612. The contact cap 613 is located in the main chamber 11. The elastic force provided by the return spring 650 can lift the start button 610 until the contact cap 613 is against the inner wall of the main chamber 11; pressing the flange 612 can drive the contact cap 613 to descend, so that the contact cap 613 presses the start switch 642.

[0052] See also Figure 7 and Figure 8 The control module 600 further includes: a movable ring 670, a ventilation cover 680 and a plurality of elastic sheets 690. The ventilation cover 680 is arranged on the inner wall of the main chamber 11. A ventilation hole 681 is provided on the side of the ventilation cover 680. The contact cap 613 is located inside the ventilation cover 680. A brim 6131 is provided on the contact cap 613. A sealing ring 700 is provided between the brim 6131 and the inner wall of the main chamber 11. When the start button 610 is pressed, the contact cap 613 can be separated from the inner wall of the main chamber 11, so that the contact cap 613 no longer blocks the ventilation hole 681. In this state, the main chamber 11 is connected to the groove 120 through the ventilation hole 681; the reset spring 650 lifts the start button 610 so that the contact cap 613 is in close contact with the inner wall of the main chamber 11 and closes the ventilation hole 681.

[0053] An installation groove 6111 is provided on the outer wall of the extension rod 611, and an elastic sheet 690 is embedded in the installation groove 6111. A trigger portion 691 is provided on the elastic sheet 690, and the trigger portion 691 is bent in a direction away from the center of the extension rod 611. A boss 622 that fits with the trigger portion 691 is provided on the shift wheel 620; in an initial state, the trigger portion 691 is exposed on the outside of the extension rod 611, and the trigger portion 691 can be retracted into the installation groove 6111 when squeezed by external force.

[0054] A storage groove 150 is also provided on the lamp body 100, and the storage groove 150 is connected with the groove 120. The movable ring 670 is located in the storage groove 150. The groove depth of the storage groove 150 is greater than the thickness of the movable ring 670. The extension rod 611 passes through the movable ring 670. The movable ring 670 is provided with a first guide slope 671 and a second guide slope 672. The first guide slope 671 and the second guide slope 672 are distributed at both ends of the movable ring 670. The first guide slope 671 and the second guide slope 672 are used to abut against the trigger part 691 so that the trigger part 691 bends toward the mounting groove 6111. The shift wheel 620 is provided with an avoidance groove 623 matching the first guide slope 671.

[0055] See also Figure 7 A ventilation groove 673 is provided on the outer wall of the movable ring 670 .

[0056] See also Figures 7 to 11 The principle of the above structure to reduce the impact of humid environment and heating problems on the flashlight is as follows:

[0057] When the start button 610 is pressed, the extension rod 611, the contact cap 613 and the elastic sheet 690 slide toward the main chamber 11 at the same time. When the elastic sheet 690 descends, it passes through the movable ring 670, and the trigger part 691 moves from the upper side of the movable ring 670 to the lower side of the movable ring 670. During this process, the trigger part 691 first contacts the first guiding slope 671 on the movable ring 670, and retracts into the mounting groove 6111 under the guidance of the first guiding slope 671. When the trigger part 691 moves to the lower side of the movable ring 670, it pops out again. Fig. 9 As shown;

[0058] See also Fig.10 and Fig.11 After the pressure on the start button 610 is removed, the return spring 650 provides elastic force to drive the start button 610 to rise. Since the trigger part 691 is located below the movable ring 670 at this time, the movable ring 670 will be lifted up together with the trigger part 691, and the first guide slope 671 of the movable ring 670 enters the avoidance groove 623, so that the movable ring 670 is embedded in the shift wheel 620. The movable ring 670 is blocked and no longer continues to rise with the trigger part 691, and the trigger part 691 is retracted into the installation groove 6111 under the guidance of the second guide slope 672. The elastic sheet 690 passes through the movable ring 670. Since the first guide slope 671 on the movable ring 670 is embedded in the avoidance groove 623 at this time, the trigger part 691 on the elastic sheet 690 will not pop out after moving from the bottom of the movable ring 670 to the top of it. Fig.10 As shown, the trigger portion 691 remains in a retracted state so that the trigger portion 691 cannot abut against the boss 622, and the start button 610 continues to rise until the brim 6131 abuts against the inner wall of the main chamber 11, as shown in FIG. Fig.11 As shown, the contact cap 613 blocks the air hole 681, and the sealing ring 700 contacts the inner wall of the main chamber 11 to provide sealing. At this time, the contact cap 613 is separated from the start switch 642, and the multi-function flashlight 10 is turned off.

[0059] When the trigger portion 691 moves from below the movable ring 670 to above it, the movable ring 670 loses support and falls under the action of gravity and falls back into the receiving groove 150 .

[0060] See also Figure 7 and Figure 8To turn on the multifunctional flashlight 10, it is only necessary to press the start button 610 again to make the elastic sheet 690 drop down. When it drops to the position of the boss 622, the contact cap 613 pops out from the mounting groove 6111. At this time, the start button 610 is released, and the contact cap 613 and the boss 622 are pressed against each other to fix the start button 610. At this time, the contact cap 613 squeezes the start switch 642, and the multifunctional flashlight 10 is in the start state. At the same time, since the start button 610 does not rise after being pressed, the contact cap 613 is staggered with the air vent 681, and the air vent 681 is no longer blocked, and the sealing ring 700 is separated from the inner wall of the main chamber 11, and the main chamber 11 is connected with the groove 120.

[0061] The start button 610 needs to be pressed when turning the multifunctional flashlight 10 on and off, and the pressure on the start button 610 is removed after the contact cap 613 pops out. When the contact cap 613 switches from a retracted state to a pop-up state, obvious vibration will be generated. The user can remove the pressure on the start button 610 when he feels the vibration generated by the contact cap 613.

[0062] It should be emphasized that when the multifunctional flashlight 10 is in the closed state, the contact cap 613 blocks the air hole 681, and the sealing ring 700 contacts the inner wall of the main chamber 11 to provide sealing, the main chamber 11 is isolated from the outside, and the multifunctional flashlight 10 is in a sealed state; after the multifunctional flashlight 10 is turned on, the contact cap 613 is offset from the air hole 681, the air hole 681 is no longer blocked, and the sealing ring 700 is separated from the inner wall of the main chamber 11, and the main chamber 11 is connected to the groove 120, so the power supply 400 and the LED light board 2 00, the hot air generated during operation can enter the groove 120 and be discharged outward through the shift wheel 620. On the one hand, the main chamber 11 is in an unsealed state, allowing the heat to be discharged to avoid the internal temperature and air pressure of the lamp body 100 being too high, which may cause the circuit board 640 to malfunction; on the other hand, after the flashlight is turned on, the gas in the main chamber 11 flows toward the location of the air vent 681, and the heated gas can dry the moisture attached to the circuit board 640 when it flows through the circuit board 640, so that the surface of the circuit board 640 remains dry, and the water vapor in the main chamber 11 is taken out. That is, the problem of excessive pressure and temperature inside the lamp body 100 caused by long-term operation of the power supply 400 and the LED light board 200 is solved, and the problem of moisture causing the circuit board 640 to get damp when the flashlight is used in a humid environment is avoided, which is conducive to improving the service life of the flashlight.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
