[0002] With the development of society and the continuous improvement of living standards, more and more consumers are buying cameras, camcorders and other photographic equipment for shooting. As we all know, most of the existing cameras, camcorders and other photographic equipment need to be in a good light environment to shoot excellent picture quality. If it is at night or under poor ambient light conditions, these photographic equipment usually need to use auxiliary equipment to enhance the lighting effect. Flashlight, as a common light reinforcement device, has been widely used in the field of photography.
[0003] As users have higher and higher requirements for shooting quality, people have higher and higher requirements for flashes. For this reason, some flashes with knobs have appeared on the market. Users can switch the functions of the flashes or adjust the parameters of the flashes by turning the knobs, so that the light emitted by the flashes can meet the user's photography needs. However, these flashes are generally connected to the shooting equipment through wired or wireless means, and users can only control whether the flashes emit light through the shooting equipment. In some cases, when the user controls the flash to emit light through the shooting equipment, the flash does not emit light normally. At this time, the user cannot confirm whether the flash is damaged and causes the flash to not emit light normally, or whether the flash cannot emit light normally because the flash is not connected to the shooting equipment correctly, which brings inconvenience to the user in using the flash.

[0033] Reference Figures 1 to 10 , and mainly refer to Figure 5 , Figure 8 and Fig.10According to the present embodiment, a flashlight with a knob (for the sake of convenience, it is sometimes referred to as a "flashlight" below). The flashlight of the present embodiment includes a flashlight body 100, a flashlight button 200 and a knob 300. A control circuit board 110 is disposed inside the flashlight body 100. The control circuit board 110 is electrically connected to a flashlight switch 111 and a light source. The flashlight switch 111 can feedback a signal to the control circuit board 110. After receiving the feedback signal from the flashlight switch 111, the control circuit board 110 can control the light source to be powered on and emit light. The flashlight button 200 is movably installed at a position on the side wall of the flashlight body 100 corresponding to the flashlight switch 111. The flashlight button 200 can squeeze or trigger the flashlight switch 111. The knob 300 is hollow inside, and is movably mounted on the side wall of the flashlight body 100. The knob 300 is movably sleeved on the outer periphery of the flashlight button 200. The knob 300 can rotate relative to the flashlight button 200. Specifically, the knob 300 is a ring-shaped member with a through hole inside. The diameter of the through hole matches the outer diameter of the flashlight button 200. The flashlight button 200 is movably mounted in the through hole inside the knob 300. At this time, the user can turn the knob 300 to rotate relative to the flashlight button 200, and the knob 300 and the flashlight button 200 do not interfere with each other. In this embodiment, the control circuit board 110 is electrically connected to an input device that can cooperate with the knob 300 and input signals to the control circuit board 110.
[0034] The control circuit board 110 of the flashlight of the present embodiment is electrically connected to a flashlight switch 111, and a flashlight button 200 is movably installed at a position corresponding to the flashlight switch 111 on the side wall of the flashlight body 100.

The operation is simple and convenient, which greatly improves the user's experience of using the flash. In addition, by setting the flash button 200 inside the knob 300, the knob 300 can rotate relative to the flash button 200, and the knob 300 and the flash button 200 can work independently without affecting each other. Moreover, the above structure is convenient for users to operate the knob 300 and the flash button 200, while reducing the surface area of the flash body 100 occupied by the knob 300 and the flash button 200, so that the structure of the flash of this embodiment is more compact, which helps to reduce the size of the flash and is also convenient for the production of the flash.
[0035] Reference Figure 2 , Figure 3 , Figure 8 and Fig.10 In order to facilitate the installation of the knob 300 on the flash body 100, in some embodiments of the utility model, the flash body 100 is provided with a fixed mounting frame 120. Specifically, the fixed mounting frame 120 is fixedly installed at the middle and upper part of the flash body 100. A clearance hole 121 for making way for the knob 300 is opened at one end of the fixed mounting frame 120, that is, the size of the clearance hole 121 is adapted to the size of the knob 300. In this embodiment, the inner diameter of the clearance hole 121 is slightly larger than the outer diameter of the knob 300. The knob 300 is rotatably installed in the clearance hole 121. The inner wall of the clearance hole 121 is provided with a flange portion 122. An end of the knob 300 close to the control circuit board 110 is detachably connected with an anti-slip component 310. The anti-slip component 310 is located in the clearance hole 121, and the anti-slip component 310 can abut against the flange portion 122 to limit the knob 300 from separating from the fixed mounting frame 120. Specifically, the anti-slip component 310 is threadedly installed on the outer wall of one end of the knob 300 close to the control circuit board 110, or the anti-slip component 310 is clamped on the outer wall of one end of the knob 300 close to the control circuit board 110. At this time, the flange portion 122 is located between the anti-slip component 310 and the upper end of the knob 300. The flange portion 122 can limit the knob 300 from moving upward or downward from the fixed mounting frame 120, so that the knob 300 can only rotate in a horizontal direction relative to the fixed mounting frame 120 or the flash body 100. By adopting the above structure, the knob 300 can be firmly installed on the flash body 100, and the assembly is simpler and more convenient.
[0036] Reference Figure 2 , Figure 5 , Figure 7 and Fig.10 In order to make the knob 300 press or trigger the input device better, in some embodiments of the present invention, the knob 300 includes a first boss 301, and the first boss 301 is arranged at one end of the knob 300 close to the control circuit board 110, or the first boss 301 is arranged at one end of the anti-dropping member 310 close to the control circuit board 110; the input device includes a first detection device 112 for detecting the first boss 301, specifically, the first detection device 112 is a contact sensor, and the first detection device 112 is fixedly mounted on the control circuit board 1 10, and the first detection device 112 is located in the moving path of the first boss 301; when the user turns the knob 300 to rotate relative to the flash body 100, the knob 300 drives the first boss 301 to move to the first detection device 112, and the first detection device 112 detects the first boss 301 and feeds back a signal to the control circuit board 110. The control circuit board 110 receives the feedback signal from the first detection device 112, and the control circuit board 110 can turn on or switch the function or parameter of the flash according to the set program, which can be determined according to actual needs.
[0037] It should be noted that in the above embodiment, the first detection device 112 is a contact sensor, and in some embodiments of the present invention, the first detection device 112 can also be selected as an infrared sensor, which can be determined according to actual needs and is not limited to the above contact sensor.
[0038] Furthermore, in certain embodiments of the present invention, the knob 300 includes two first bosses 301, which are arranged at intervals at one end of the knob 300 close to the control circuit board 110, or the two first bosses 301 are arranged at intervals at one end of the anti-slip component 310 close to the control circuit board 110; the input device includes two first detection devices 112, which are fixedly installed on the control circuit board 110 at intervals, one of the first detection devices 112 is used to detect one of the first bosses 301, and the other first detection device 112 is used to detect the other first boss 301. By adopting the above structure, when the user turns the knob 300 to rotate relative to the flash body 100, one of the first bosses 301 can trigger one of the first detection devices 112 accordingly, and the first detection device 112 feeds back a signal to the control circuit board 110, and the control circuit board 110 turns on or switches the function or parameters of the flash. Then the user continues to turn the knob 300 and causes another first boss 301 to squeeze or trigger another first detection device 112, and the other first detection device 112 feeds back a signal to the control circuit board 110, and the control circuit board 110 turns on or switches the function or parameters of the flash, thereby facilitating the user to control or switch the function or parameters of the flash through the knob 300 and facilitating the user to use the flash.
[0039] Reference Figure 1 , Figure 4 , Figure 6 and Fig.10In order to facilitate the user to position and rotate the knob 300, in some embodiments of the present utility model, a gear positioning structure is provided between the fixed mounting frame 120 and the knob 300. Specifically, the gear positioning structure includes a movable positioning pin 410, a positioning member 420 and an elastic member 430. The positioning member 420 is fixedly arranged on the knob 300, and the positioning member 420 has more than two arc-shaped grooves 421 arranged in sequence along the circumference of the knob 300; the fixed mounting frame 120 is provided with a connecting groove 123 connected to the clearance hole 121, and the movable positioning pin 410 is movably installed inside the connecting groove 123 of the fixed mounting frame 120, and the movable positioning pin 410 can extend into the clearance hole 121 or the movable positioning pin 410 can withdraw from the clearance hole 121, and the elastic member 430 is arranged inside the connecting groove 123 of the fixed mounting frame 120, one end of the elastic member 430 abuts against the inner wall of the fixed mounting frame 120 or the connecting groove 123, and the other end of the elastic member 430 abuts against the movable positioning pin 410. When the knob 300 drives the positioning member 420 to rotate and aligns the arc groove 421 with the movable positioning pin 410, the elastic member 430 can drive the movable positioning pin 410 to move into the clearance hole 121 and embed into the corresponding arc groove 421, and the elastic member 430 can keep the movable positioning pin 410 in the state of extending into the clearance hole 121. In this embodiment, the positioning member 420 is sequentially arranged with three arc grooves 421 along the circumference of the knob 300. The movable positioning pin 410 cooperates with the three arc grooves 421, so that the knob 300 can achieve three-level positioning to meet the user's usage requirements.
[0040] Furthermore, in order to prevent the user from turning the knob 300 beyond the set range, in certain embodiments of the present invention, a rotation limit assembly is provided between the knob 300 and the fixed mounting frame 120, and the rotation limit assembly includes a limit protrusion 510 and a limit groove 520 that cooperate with each other to limit; one of the limit protrusion 510 and the limit groove 520 is provided on the outer wall of the knob 300, and the other is provided on the inner wall of the clearance hole 121, and the limit protrusion 510 is at least partially embedded in the limit groove 520; when the knob 300 rotates forward or reversely relative to the fixed mounting frame 120, the limit protrusion 510 can move back and forth along the limit groove 520. In an embodiment of the utility model, the limiting protrusion 510 is integrally formed on the inner wall of the clearance hole 121 of the fixed mounting frame 120, and the limiting groove 520 is opened on the outer wall of the knob 300. When the knob 300 is correspondingly embedded in the clearance hole 121 of the fixed mounting frame 120, the limiting protrusion 510 is correspondingly embedded in the limiting groove 520. When the knob 300 rotates relative to the fixed mounting frame 120 and makes the limiting protrusion 510 abut against the end of the limiting groove 520, the limiting protrusion 510 cooperates with the limiting groove 520 to limit the knob 300 from continuing to rotate relative to the fixed mounting frame 120 along the original rotation direction. At this time, the knob 300 can only rotate in the opposite direction relative to the fixed mounting frame 120. By adopting the above structure, it is possible to effectively avoid the knob 300 from rotating beyond the set range and being damaged, which helps to protect the flash.
[0041] It should be noted that, in the above-mentioned embodiment, the limiting protrusion 510 is integrally formed on the inner wall of the clearance hole 121 of the fixed mounting frame 120, and the limiting groove 520 is opened on the outer wall of the knob 300. In certain embodiments of the present utility model, the limiting protrusion 510 is arranged on the outer wall of the knob 300, and the limiting groove 520 is opened on the inner wall of the clearance hole 121 of the fixed mounting frame 120. The specific configuration can be determined according to actual needs.
[0042] Further, in order to facilitate the user to know whether the flashlight is in a state where it can emit light normally, in some embodiments of the present utility model, the flashlight button 200 is a light-transmitting member, that is, the flashlight button 200 is made of a light-transmitting material, specifically, the flashlight button 200 can be a light-transmitting silicone member or a plastic member, and the control circuit board 110 is electrically connected with a light-emitting device that indicates whether the flashlight can work normally or not, and the light-emitting device can emit light toward the flashlight button 200. Specifically, the light-emitting device includes a first LED light source 610 that can emit red light when powered on and a second LED light source 620 that can emit green light when powered on, and the first LED light source 610 and the second LED light source 620 are fixedly installed at positions on the surface of the control circuit board 110 corresponding to the flashlight button 200. When the flash is in a state where it can emit light normally, the control circuit board 110 controls the second LED light source 620 to emit green light, and the green light is irradiated to the flash button 200. At this time, the user can know that the flash is in a state where it can emit light normally by observing the color of the flash button 200; if the flash is in a state where it cannot emit light normally, the control circuit board 110 controls the first LED light source 610 to emit red light, and the red light is irradiated to the flash button 200. At this time, the user can know that the flash is in a state where it cannot emit light normally by observing the color of the flash button 200, which is convenient for the user to use the flash.
