Description
Technical Field
[0001] The invention relates to the technical field of laser hair removal devices, in particular to a small gun-type laser hair removal device with foldable power-off control. Background Art
[0002] Laser hair removal technology has gradually developed and matured since the 1990s. Its core principle is based on the "selective photothermolysis theory", which uses lasers of specific wavelengths (such as 810nm) to target the melanin in hair follicles, destroying the hair follicle growth tissue through thermal effects to achieve permanent hair removal. Currently, laser hair removal devices on the market are mainly divided into two categories: large medical-grade equipment and portable home devices. Due to size, cost and safety limitations, home devices mostly use semiconductor lasers or intense pulsed light (IPL) technology, but the following technical pain points still exist.
[0003] Traditional hair removal devices are large in size and require an external power supply. In addition, the laser generating module lacks a folding design. For example, the laser hair removal device disclosed in patent CN117530769A includes a housing assembly, a laser assembly, a heat dissipation assembly, and a power supply assembly. The housing assembly includes a main housing with a light outlet and a back housing, the back housing is connected to the main housing, and is enclosed with the main housing to form a receiving cavity; the heat dissipation assembly includes a radiator and a heat dissipation fan provided in the receiving cavity, the radiator includes a heat dissipation base and a plurality of heat dissipation fins connected to the heat dissipation base, and the tail ends of the heat dissipation fins correspond to the heat dissipation fan; the laser assembly includes a light guide, a laser, and a sapphire provided at the light outlet. The optical components are arranged around the laser and form a closed light output channel to converge the laser beams emitted by multiple lasers and pass them through the sapphire in sequence; the power supply component is arranged at the end of the accommodating cavity away from the light outlet, and the power supply component includes a battery and a control board. The control board is fixedly connected to the main shell and is electrically connected to the battery, laser component and heat dissipation component respectively. The integrated design of the laser hair removal device cannot be folded, occupies a large space, and is therefore inconvenient to carry. In addition, the power-off control of existing laser hair removal devices mostly relies on physical switches and lacks a foldable trigger power-off design. The device may still be started by accident when not in use, resulting in the risk of laser leakage.
[0004] To this end, we provide a small gun-type laser hair removal device with a foldable power-off control. Through the foldable handle and laser head module, the device size is minimized and easy to carry. At the same time, when folded, the power-off mechanism is automatically triggered to completely cut off the power supply and avoid accidental light emission, thereby solving the above-mentioned problems.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0035] Please refer to Figures 1 to 11, as an embodiment of the present invention, a small gun-shaped laser hair removal device with folding power-off control includes a laser hair removal device main body 1. A handle 2 is hinged at the bottom end of the laser hair removal device main body 1. An installation frame 5 is fixed inside the laser hair removal device main body 1. A U-shaped cover plate 6 is fixed on the top of the installation frame 5. An activity frame 7 is arranged inside the U-shaped cover plate 6. The activity frame 7 is connected to the installation frame 5 through an elastic component. The activity frame 7 can move up and down inside the U-shaped cover plate 6. A pressing rod 10 is fixed at the bottom of the activity frame 7 and penetrates through the installation frame 5 and the laser hair removal device main body 1. A connecting rod 13 is fixed at the bottom of the activity frame 7 and penetrates through the installation frame 5. A travel switch 23 for controlling the power on and off of the laser hair removal device is fixed on the installation frame 5. A contact switch 30 is installed inside the travel switch 23. A top rod 25 is movably clamped on the travel switch 23;
[0036] The connecting rod 13 and the top rod 25 are配合 through a linkage structure. When the connecting rod 13 moves up and down, it can带动 the top rod 25 to slide inside the travel switch 23. When the top rod 25 is in extrusion contact with the contact switch 30, the laser hair removal device is powered off. When the top rod 25脱离挤压接触 with the contact switch 30, the laser hair removal device is powered on.
[0037] In this embodiment, when a small gun-shaped laser hair removal device with folding power-off control is in use, after the laser hair removal device main body 1 finishes use, the handle 2 is flipped to fold and store the laser hair removal device main body 1. When folding, the handle 2 flips and挤压 the pressing rod 10 to带动 the activity frame 7 to move upward. When the activity frame 7 moves upward, it will同时带动 the connecting rod 13 to move upward. When the connecting rod 13 moves upward, it拉动 the swing arm 16 to rotate against the elastic force of the second spring 20. When the first convex rod 18 rotates to the same vertical line as the second convex rod 19, the stretching amount of the second spring 20 reaches the maximum value. After that, when the swing arm 16 continues to deflect, the second spring 20瞬间收缩复位,带动 the swing arm 16 to瞬间偏摆 to the other side从而挤压 the top block 22,带动 the rotating rod 21 to rotate. When the rotating rod 21 rotates, it带动 the clamping rod 27 to slide inside the rectangular groove 26从而带动 the top rod 25 to move into the travel switch 23. And after the second spring 20 contracts, the elastic force of the second spring 20 is used to锁定 the position of the top rod 25 after it moves into the travel switch 23. After the top rod 25 moves into the travel switch 23, it is in extrusion contact with the contact switch 30 inside the travel switch 23. By挤压 the contact switch 30, a power-off signal of the power supply is triggered, so that the laser hair removal device is powered off;
[0038] Therefore, in the present invention, the handle 2 and the laser hair removal device main body 1 are foldable, which reduces the volume of the laser hair removal device and makes it便于携带. At the same time, the power-off mechanism can be triggered after folding to彻底切断 the power supply and avoid accidental light emission.
[0039] As a further solution of the present invention, a hinged rod 4 is fixed at the top of the handle 2. A hinged ring 3 is fixed at the bottom of the laser hair removal device main body 1. The hinged ring 3 is活动套设在 the hinged rod 4.
[0040] In this embodiment, a hinged rod 4 is fixed to the top of the handle 2, and a hinged ring 3 is fixed to the bottom of the laser hair removal device body 1. The hinged ring 3 is movably mounted on the hinged rod 4. The hinged ring 3 can rotate around the hinged rod 4, so that the laser hair removal device body 1 can be flipped around the handle 2. The flipping between the laser hair removal device body 1 and the handle 2 can reduce the size of the laser hair removal device and make it easy to carry.
[0041] As a further solution of the present invention, the elastic component includes a limiting rod 8 fixed on the mounting frame 5, the limiting rod 8 is set through the movable frame 7, and a first spring 9 is movably sleeved on the limiting rod 8. The two ends of the first spring 9 are respectively fixed to the movable frame 7 and the mounting frame 5.
[0042] In this embodiment, when the pressure rod 10 is squeezed, it will move upward and drive the movable frame 7 to overcome the elastic force of the first spring 9 and move upward, thereby driving the connecting rod 13 at the bottom of the movable frame 7 to move upward. At the same time, when the pressure rod 10 is no longer squeezed, the first spring 9 elastically resets and can pull the movable frame 7 to move downward and reset, driving the connecting rod 13 at the bottom of the movable frame 7 to move downward.
[0043] As a further solution of the present invention, a limiting groove body 12 whose inner surface dimensions are adapted to the outer surface dimensions of the pressure rod 10 is fixed on the mounting frame 5 , and the pressure rod 10 is movably engaged in the inner portion of the limiting groove body 12 .
[0044] In this embodiment, the pressure rod 10 is movably connected to the limiting groove 12, and the limiting groove 12 can limit the pressure rod 10 when it moves up and down, thereby preventing the pressure rod 10 from positionally shifting when it moves up and down and ensuring stability during movement.
[0045] As a further solution of the present invention, the pressure rod 10 is set through the shell of the laser hair removal device main body 1 and is extended to the outside of the shell of the laser hair removal device main body 1. A pressure plate 11 is fixed to the surface of the pressure plate 11 with a soft rubber layer fixedly adhered.
[0046] In this embodiment, the pressure plate 11 can increase the contact area between the pressure rod 10 and the handle 2, and increase the stability of the contact between the handle 2 and the pressure rod 10. The soft rubber layer is soft and elastic, which can reduce the wear between the handle 2 and the laser hair removal device body 1 after it is folded.
[0047] As a further solution of the present invention, the linkage structure includes a first fixing frame 14 and a second fixing frame 15 fixed on the mounting frame 5, the first fixing frame 14 is hinged with a swing arm 16, a hinge plate 17 is provided between the swing arm 16 and the connecting rod 13, and the two ends of the hinge plate 17 are respectively hinged to the connecting rod 13 and the swing arm 16, a second protrusion 19 is fixed on the second fixing frame 15, a first protrusion 18 is fixed on the swing arm 16, a second spring 20 is connected between the first protrusion 18 and the second protrusion 19, a rotating rod 21 is hinged on the first fixing frame 14, a top block 22 is fixed to one end of the rotating rod 21, and the other end is connected to the top rod 25 through a movable clip, and an elastic reset component is provided on the mounting frame 5 when the top rod 25 moves.
[0048] In this embodiment, when folding, the handle 2 flips over and squeezes the pressure rod 10 to drive the movable frame 7 to move upward. The upward movement of the movable frame 7 will also drive the connecting rod 13 to move upward. When the connecting rod 13 moves upward, it pulls the swing arm 16 to overcome the elastic force of the second spring 20 to rotate. When the first protruding rod 18 rotates to the same vertical line as the second protruding rod 19, the stretching amount of the second spring 20 reaches the maximum value. After that, when the swing arm 16 continues to deflect, the second spring 20 instantly contracts and resets, driving the swing arm 16 to deflect to the other side instantly, thereby squeezing the top block 22, driving the rotating rod 21 to rotate, and the rotating rod When 21 rotates, it drives the clamping rod 27 to slide in the rectangular groove 26, thereby driving the push rod 25 to move into the limit switch 23, and after the second spring 20 contracts, the elastic force of the second spring 20 is used to lock the position of the push rod 25 after it moves into the limit switch 23. After the push rod 25 moves to the inside of the limit switch 23, it is squeezed and contacted with the contact switch 30 inside the limit switch 23, and the elastic force of the second spring 20 is used to squeeze and contact the push rod 25 with the contact switch 30 and lock the position. The power-off signal is triggered by the squeezing of the contact switch 30, thereby powering off the laser hair removal device.
[0049] It should be noted that when the stretching amount of the second spring 20 reaches the maximum value, the second spring 20 contracts and resets instantly when the swing arm 16 continues to deflect, driving the swing arm 16 to swing to the other side instantly, thereby squeezing the top block 22. At this time, during the elastic reset process of the second spring 20, the connecting rod 13 will be pulled back downward for a distance.
[0050] As a further solution of the present invention, the movable clamping member includes a rectangular groove body 26 fixed to the end of the top rod 25 and a clamping rod 27 fixed to the end of the rotating rod 21 , and the clamping rod 27 is movably clamped inside the rectangular groove body 26 .
[0051] In this embodiment, when the rotating rod 21 rotates, it drives the clamping rod 27 to rotate, so that the clamping rod 27 slides in the rectangular groove 26 to drive the push rod 25 to move horizontally.
[0052] As a further solution of the present invention, the elastic reset assembly includes a limiting hole seat 24 fixed on the mounting frame 5, a push rod 25 is inserted into the limiting hole seat 24, a fixing ring 28 is fixed on the push rod 25, and a third spring 29 movably sleeved on the push rod 25 is provided between the fixing ring 28 and the limiting hole seat 24.
[0053] In this embodiment, when the laser hair removal device is used, it needs to be re-energized, the handle 2 is flipped downward and reset, and the pressure rod 10 is manually pressed again to drive the movable frame 7 to move upward, thereby driving the connecting rod 13 to move upward, and driving the swing arm 16 to flip in the opposite direction, so that the swing arm 16 is reset and the pressure on the top block 22 is released. When the top block 22 is no longer squeezed, the third spring 29 elastically resets, squeezes the fixing ring 28, and drives the push rod 25 to move out of the travel switch 23, so that the contact switch 30 is no longer squeezed and the power off signal is no longer triggered, so that the laser hair removal device is powered on.
[0054] As a further solution of the present invention, a through groove with inner dimensions matching the outer dimensions of the pressure rod 10 is opened on the bottom shell of the laser hair removal device body 1, and the pressure rod 10 is movably engaged in the through groove, and a sealing ring is fixedly adhered to the inner wall of the through groove.
[0055] In this embodiment, a through groove with inner dimensions matching the outer dimensions of the pressure rod 10 is opened on the bottom shell of the laser hair removal device main body 1, and the pressure rod 10 is movably engaged in the through groove. A sealing ring is fixedly adhered to the inner wall of the through groove. When the pressure rod 10 is movably engaged in the through groove, the pressure rod 10 can move in and out of the shell of the laser hair removal device main body 1, and the sealing ring is used to seal the through groove of the bottom shell of the laser hair removal device main body 1, thereby reducing the influence of water vapor entering the interior of the laser hair removal device main body 1 on the internal components.
[0056] As a further solution of the present invention, the laser hair removal device body 1 has a built-in power supply, and the power supply is electrically connected to the limit switch 23 through a wire.
[0057] In this embodiment, the power supply is electrically connected to the travel switch 23 via a wire, and the travel switch 23 can control the power on and off. When the push rod 25 is in squeeze contact with the contact switch 30, the laser hair removal device is powered off, and when the push rod 25 is out of squeeze contact with the contact switch 30, the laser hair removal device is powered on.
[0058] The working principle of the invention is as follows: when the small gun-type laser hair removal device with foldable power-off control is used, after the main body 1 of the laser hair removal device is used, the handle 2 is flipped to fold the main body 1 of the laser hair removal device. When folding, the handle 2 is flipped and the pressure rod 10 is squeezed to drive the movable frame 7 to move upward. The upward movement of the movable frame 7 will also drive the connecting rod 13 to move upward. When the connecting rod 13 moves upward, it pulls the swing arm 16 to overcome the elastic force of the second spring 20 to rotate. When the first protruding rod 18 rotates to the same vertical line as the second protruding rod 19, the stretching amount of the second spring 20 reaches the maximum value. After that, when the swing arm 16 continues to deflect, the second spring 20 The instantaneous contraction and reset drive the swing arm 16 to instantly deflect to the other side, thereby squeezing the top block 22 and driving the rotating rod 21 to rotate. When the rotating rod 21 rotates, it drives the clamping rod 27 to slide in the rectangular groove 26, thereby driving the top rod 25 to move into the limit switch 23. After the second spring 20 contracts, the elastic force of the second spring 20 is used to lock the position of the top rod 25 after it moves into the limit switch 23. After the top rod 25 moves into the inside of the limit switch 23, it is squeezed and contacted with the contact switch 30 inside the limit switch 23. The squeezing of the contact switch 30 triggers a power-off signal, thereby powering off the laser hair removal device.
[0059] When the laser hair removal device is in use, it needs to be powered on again, the handle 2 is flipped downward to reset, and the pressure rod 10 is manually pressed again to drive the movable frame 7 to move upward, thereby driving the connecting rod 13 to move upward, driving the swing arm 16 to flip in the opposite direction, so that the swing arm 16 is reset and the pressure on the top block 22 is released. When the top block 22 is no longer squeezed, the third spring 29 elastically resets and squeezes the fixing ring 28, driving the push rod 25 to move out of the travel switch 23, so that the contact switch 30 is no longer squeezed and the power off signal is no longer triggered, so that the laser hair removal device is powered on;
[0060] Therefore, the present invention reduces the size of the laser hair removal device by folding the handle 2 and the laser hair removal device body 1 to make it easy to carry. At the same time, the power-off mechanism can be triggered after folding to completely cut off the power supply and avoid accidental light emission. This solves the problem that the power-off control of existing laser hair removal devices mostly relies on physical switches and lacks a foldable trigger-type power-off design. The device may still be accidentally started when not in use, resulting in the risk of laser leakage.
[0061] The above embodiments are exemplary rather than restrictive, so any technical solution that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
