Description

Technical Field

[0001] The present invention relates to the technical field of laser hair removal devices, and specifically to a waterproof, multi-angle lockable handheld laser hair removal device. Background Art

[0002] In the field of beauty instruments, the technological innovation of handheld laser hair removal devices has always centered around user experience, safety, and functionality. In the existing hair removal device designs, there are still significant deficiencies in the coordinated optimization of waterproof performance, angle adjustment flexibility, and heat dissipation systems, which are specifically manifested in the following aspects: Traditional hair removal devices are vulnerable to water vapor intrusion when used in humid environments or cleaning scenarios, leading to short circuits or component damage. For example, some existing devices adopt a simple mesh heat dissipation design. Although water droplets are blocked by a waterproof and breathable layer, there is still a risk of water vapor entering the device through the mesh during use; in addition, the efficient heat dissipation of hair removal devices relies on an open air duct, but such a design will destroy the sealing performance and increase the risk of water ingress. For example, the waterproof and heat dissipation structure of some existing devices realizes water vapor isolation through a combination of a hydrophobic film and a hydrophilic film, but it is not integrated into the overall heat dissipation system of the hair removal device, resulting in limited heat dissipation efficiency; In addition, most existing hair removal devices adopt a fixed-angle design, and users need to frequently adjust their body postures to adapt to the device, resulting in inconvenient operation. For example, the adjustment component of a multi-angle adjustable hair removal device disclosed in Patent CN118615012B only supports rotation at limited angles and lacks a multi-dimensional locking function, making it easy for the angle to shift during the hair removal process due to accidental touch, affecting the accuracy of spot coverage; another example is a handheld laser hair removal device disclosed in Patent CN118634030A, although it mentions a rotating hub design, it is mainly used for guiding the heat dissipation airflow and does not involve an angle locking function.

[0003] Therefore, we provide a waterproof, multi-angle lockable handheld laser hair removal device to solve the above-mentioned problems. Summary of the Invention

When the main shaft rotates, it will intermittently drive the first driven shaft and the third driven shaft to rotate respectively. When the first driven shaft rotates, the third driven shaft does not rotate. When the third driven shaft rotates, the first driven shaft does not rotate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When in use, start the bidirectional servo motor to drive the main shaft to rotate. While the main shaft rotates, it will drive the second driven shaft to rotate intermittently and drive the rotating arm to swing back and forth clockwise and counterclockwise intermittently. When the second driven shaft rotates, it will drive the second gear to rotate. When the second gear rotates, it will synchronously drive the third gear to rotate. When the third gear rotates, it will drive the articulated rod to rotate and then drive the hair remover body to rotate. By driving the main shaft to rotate one week each time by the bidirectional servo motor, the hair remover body on the articulated rod will rotate a fixed angle. At the same time, each time the main shaft rotates one week, it will also drive the rotating arm to swing once clockwise and counterclockwise respectively. When the rotating arm rotates counterclockwise, it will drive the engaging teeth to engage with the third gear and lock the third gear after rotating a certain angle, that is, lock the hair remover body after rotating a certain angle. When the rotating arm rotates clockwise, it will drive the engaging teeth to unlock from the third gear, that is, during the process of the main shaft rotating one week, first the main shaft will drive the rotating arm to rotate clockwise to unlock the third gear, then the main shaft drives the second gear to rotate to drive the third gear to rotate a certain angle to drive the hair remover body to rotate a certain angle, and then the main shaft drives the rotating arm to rotate counterclockwise to lock the third gear after rotating a certain angle.

[0016] Therefore, by driving the main shaft to rotate a fixed angle each time by the bidirectional servo motor, the present invention can make the hair remover body rotate a certain angle and then be locked. Thus, when using the hair remover, the user does not need to frequently adjust the body posture to adapt to the device, and the operation is convenient. In addition, after the hair remover body is adjusted at multiple angles and mechanically locked, the angle of the hair remover body will not shift due to accidental touch after the angle adjustment, improving the use stability of the hair remover body after the angle adjustment; In addition, an air-cooling structure for cooling the inside of the hair remover body and removing water vapor is provided inside the hair remover body of the present invention. The air-cooling structure includes heat dissipation fins fixed inside the hair remover body. A water-cooling pipe is inserted through the inside of the heat dissipation fins, and the water-cooling pipe is in contact with the surface of the laser. A fan is fixed inside the hair remover body. Through the water-cooling pipe, water-cooling heat dissipation can be carried out when the laser operates, and at the same time, heat exchange is carried out by using the coolant inside in contact with the laser. The water-cooling pipe can simultaneously transfer heat to the heat dissipation fins. Starting the fan can carry out air-cooling heat dissipation on the coolant inside the water-cooling pipe and the heat absorbed by the heat dissipation fins. Therefore, the present invention can carry out water-cooling and air-cooling heat dissipation when the laser operates. At the same time, since the fan is arranged on one side of the heat dissipation hole, when the hair remover is in use, the humid water vapor is difficult to enter the inside of the hair remover body through the heat dissipation hole due to the wind force of the fan. In addition, the heat dissipated by the heat dissipation fins and the water-cooling pipe will also form a temperature difference on both sides of the heat dissipation hole, so that the water vapor entering the inside of the hair remover body through the heat dissipation hole is dried by the hot air, thus achieving the purpose of waterproofing. And the present invention integrates the waterproof and heat dissipation structure together, effectively improving the heat dissipation and waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

When the main shaft 6 rotates, it will drive the second driven shaft 9 to rotate intermittently and intermittently drive the rotating arm 21 to swing back and forth clockwise and counterclockwise; An air-cooling structure for dissipating heat and removing water vapor inside the hair removal device main body 1 is further arranged in the hair removal device main body 1.

[0030] In this embodiment, during use, the driving spindle 6 is rotated. While the spindle 6 rotates, it drives the second driven shaft 9 to rotate intermittently and drives the rotating arm 21 to swing reciprocally clockwise and counterclockwise intermittently. When the second driven shaft 9 rotates, it drives the second gear 11 to rotate. When the second gear 11 rotates, it synchronously drives the third gear 12 to rotate. When the third gear 12 rotates, it drives the hinge rod 4 to rotate and then drives the hair remover main body 1 to rotate. By driving the spindle 6 to rotate one full circle each time, the hair remover main body 1 on the hinge rod 4 is driven to rotate a fixed angle. At the same time, each time the spindle 6 rotates one full circle, it also drives the rotating arm 21 to swing once clockwise and counterclockwise respectively. When the rotating arm 21 rotates counterclockwise, it drives the engaging teeth 22 to engage with the third gear 12 and lock the third gear 12 after rotating a certain angle, that is, lock the hair remover main body 1 after rotating a certain angle. When the rotating arm 21 rotates clockwise, it drives the engaging teeth 22 to unlock from the third gear 12, that is, during the process of the spindle 6 rotating one full circle, first the spindle 6 drives the rotating arm 21 to rotate clockwise to unlock the third gear 12, then the spindle 6 drives the second gear 11 to rotate to drive the third gear 12 to rotate a certain angle to drive the hair remover main body 1 to rotate a certain angle, and then the spindle 6 drives the rotating arm 21 to rotate counterclockwise to lock the third gear 12 after rotating a certain angle. Repeating the above actions can perform rotational adjustment of the hair remover main body 1 by a certain angle each time and perform mechanical locking, achieving the purpose of multi-angle adjustment of the hair remover main body 1.

[0031] As a further solution of the present invention, a bidirectional servo motor 7 is fixed on the additional housing 5. The spindle 6 is installed at the output end of the bidirectional servo motor 7 and is driven to rotate by the bidirectional servo motor 7. And an adjustment button 35 for controlling the start-stop and forward-reverse rotation of the bidirectional servo motor 7 is fixed on the handle 2.

[0032] In this embodiment, an encoder is installed on the bidirectional servo motor 7, which can make the bidirectional servo motor 7 drive the spindle 6 to rotate one full circle at a fixed angle each time. The bidirectional servo motor 7 is started to drive the spindle 6 to rotate. While the spindle 6 rotates, it drives the second driven shaft 9 to rotate intermittently and drives the rotating arm 21 to swing reciprocally clockwise and counterclockwise intermittently. The adjustment button 35 is electrically connected to the bidirectional servo motor 7 through a wire. By the adjustment button 35, the start-stop of the bidirectional servo motor 7 can be controlled to make the hair remover main body 1 stop rotating after being adjusted to the required angle, and the forward-reverse rotation of the bidirectional servo motor 7 can be controlled by the adjustment button 35, achieving the purpose of bidirectional angle adjustment of the hair remover main body 1 clockwise and counterclockwise.

[0033] As a further solution of the present invention, the linkage structure includes a first driven shaft 8, a third driven shaft 13, a fourth driven shaft 17 and a rotating rod 20 rotatably arranged on the additional housing 5. A rotating arm 21 is fixed on the rotating rod 20. The first driven shaft 8 and the second driven shaft 9 are driven by a first gear mechanism. When the first driven shaft 8 rotates, it will drive the second driven shaft 9 to rotate synchronously. The third driven shaft 13 and the fourth driven shaft 17 are driven by a second gear mechanism. When the third driven shaft 13 rotates, it will drive the fourth driven shaft 17 to rotate synchronously. The fourth driven shaft 17 and the rotating rod 20 are cooperatively driven by a swing mechanism. When the fourth driven shaft 17 rotates, it will drive the rotating rod 20 to rotate back and forth clockwise and counterclockwise; The main shaft 6 and the first driven shaft 8, the third driven shaft 13 are cooperatively driven by an intermittent mechanism. When the main shaft 6 rotates, it will intermittently drive the first driven shaft 8 and the third driven shaft 13 to rotate respectively. When the first driven shaft 8 rotates, the third driven shaft 13 does not rotate. When the third driven shaft 13 rotates, the first driven shaft 8 does not rotate.

[0034] In this embodiment, the main shaft 6 and the first driven shaft 8, the third driven shaft 13 are cooperatively driven by an intermittent mechanism. When the main shaft 6 rotates, it will intermittently drive the first driven shaft 8 and the third driven shaft 13 to rotate respectively. When the first driven shaft 8 rotates, the third driven shaft 13 does not rotate. When the third driven shaft 13 rotates, the first driven shaft 8 does not rotate. When the first driven shaft 8 rotates, since the first driven shaft 8 and the second driven shaft 9 are driven by a first gear mechanism, when the first driven shaft 8 rotates, it will drive the second driven shaft 9 to rotate synchronously. When the second driven shaft 9 rotates, it will drive the second gear 11 to rotate. The second gear 11 meshes with the third gear 12, thereby driving the articulated rod 4 on the third gear 12 to rotate, and further driving the hair remover main body 1 to rotate. In addition, when the third driven shaft 13 rotates, since the third driven shaft 13 and the fourth driven shaft 17 are driven by a second gear mechanism, when the third driven shaft 13 rotates, it will drive the fourth driven shaft 17 to rotate synchronously. By using the cooperation of the swing mechanism between the fourth driven shaft 17 and the rotating rod 20, when the fourth driven shaft 17 rotates, it will drive the rotating rod 20 to rotate back and forth clockwise and counterclockwise. When the rotating rod 20 rotates counterclockwise, it drives the rotating arm 21 to rotate counterclockwise, which will drive the engaging teeth 22 to engage with the third gear 12 and lock the third gear 12 after rotating a certain angle, that is, lock the hair remover main body 1 after rotating a certain angle. When the rotating rod 20 rotates clockwise, it will drive the rotating arm 21 to rotate clockwise. When the rotating arm 21 rotates clockwise, it will drive the engaging teeth 22 to unlock from the third gear 12.

[0035] As a further solution of the present invention, the first gear mechanism includes a first gear 10 fixed on the first driven shaft 8, and the first gear 10 meshes with the second gear 11 for transmission.

[0036] In this embodiment, when the first driven shaft 8 rotates, it drives the first gear 10 to rotate, and the first gear 10 drives the second gear 11 to rotate through meshing transmission.

[0037] As a further solution of the present invention, the second gear mechanism includes a fourth gear 18 fixed on the third driven shaft 13 and a fifth gear 19 fixed on the fourth driven shaft 17, and the fourth gear 18 meshes with the fifth gear 19.

[0038] In this embodiment, when the third driven shaft 13 rotates, it drives the fourth gear 18 to rotate, and the meshing of the fourth gear 18 with the fifth gear 19 drives the fifth gear 19 to rotate, thereby driving the fourth driven shaft 17 to rotate.

[0039] As a further solution of the present invention, the intermittent mechanism includes a driving wheel 14 fixed on the main shaft 6, a first driven wheel 15 fixed on the first driven shaft 8, and a second driven wheel 16 fixed on the third driven shaft 13, and the driving wheel 14 is respectively in transmission cooperation with the first driven wheel 15 and the second driven wheel 16.

[0040] In this embodiment, when the main shaft 6 rotates, it drives the driving wheel 14 to rotate. The driving wheel 14 is respectively in transmission cooperation with the first driven wheel 15 and the second driven wheel 16. When the driving wheel 14 rotates continuously, it drives the first driven wheel 15 and the second driven wheel 16 to rotate intermittently, and further drives the first driven shaft 8 and the third driven shaft 13 to rotate intermittently.

[0041] As a further solution of the present invention, the swinging mechanism includes a turntable 23 fixed at the bottom of the fourth driven shaft 17. A convex rod 24 is fixed on the turntable 23. A swing arm 25 is fixed on the rotating rod 20. A limiting groove 26 is formed on the swing arm 25, and the convex rod 24 is movably clamped inside the limiting groove 26.

[0042] In this embodiment, when the fourth driven shaft 17 rotates, it drives the turntable 23 to rotate. The rotation of the turntable 23 drives the convex rod 24 to rotate. By movably clamping the convex rod 24 inside the limiting groove 26, it drives the swing arm 25 to reciprocally swing. When the swing arm 25 reciprocally swings, it drives the rotating rod 20 to rotate clockwise and counterclockwise reciprocally. When the rotating rod 20 rotates clockwise and counterclockwise reciprocally, it drives the rotating arm 21 to rotate clockwise and counterclockwise reciprocally, thereby driving the locking teeth 22 to rotate clockwise and counterclockwise reciprocally.

[0043] As a further solution of the present invention, a limiting component for the reciprocal swinging of the rotating arm 21 in the clockwise and counterclockwise directions is further provided between the rotating arm 21 and the additional housing 5. The limiting component includes a limiting rod 28 fixed on the rotating arm 21 and an arc-shaped groove 27 formed on the additional housing 5, and the limiting rod 28 is movably clamped inside the arc-shaped groove 27.

[0044] In this embodiment, the limiting rod 28 is movably clamped inside the arc-shaped groove 27, which can limit the clockwise and counterclockwise reciprocating rotation of the rotating arm 21, ensure the stability during its rotation, and prevent its position from shifting during rotation.

[0045] As a further solution of the present invention, the air-cooling structure includes heat dissipation fins 30 fixed inside the hair removal device main body 1. A water-cooling pipe 31 is inserted through the heat dissipation fins 30. One end of the water-cooling pipe 31 is in contact with the surface of the laser 29 installed on the hair removal device main body 1. A fan 32 is fixed inside the hair removal device main body 1 and on one side of the heat dissipation fins 30. Heat dissipation holes 33 are formed on the other side of the heat dissipation fins 30 on the housing of the hair removal device main body 1.

[0046] In this embodiment, the water-cooling pipe 31 can perform water-cooling heat dissipation on the laser 29 during operation and exchange heat with the laser 29 by using the internal coolant in contact with it. The water-cooling pipe 31 can simultaneously transfer heat to the heat dissipation fins 30. Starting the fan 32 can perform air-cooling heat dissipation on the coolant inside the water-cooling pipe 31 and the heat absorbed by the heat dissipation fins 30. Therefore, the present invention can perform water-cooling and air-cooling heat dissipation on the laser 29 during operation. At the same time, since the fan 32 is arranged on one side of the heat dissipation holes 33, when the hair removal device is in use, the humid water vapor is difficult to enter the interior of the hair removal device main body 1 through the heat dissipation holes 33 due to the wind force of the fan 32. In addition, the heat dissipated by the heat dissipation fins 30 and the water-cooling pipe 31 will also form a temperature difference on both sides of the heat dissipation holes 33, so that the water vapor entering the interior of the hair removal device main body 1 through the heat dissipation holes 33 can be dried by the hot air, thus achieving the purpose of waterproofing. The waterproof and heat dissipation structure is integrated together, effectively improving the heat dissipation and waterproof effect.

[0047] As a further solution of the present invention, a switch button 34 for controlling the start and stop of the laser 29 and the fan 32 is fixed on the hair removal device main body 1.

[0048] In this embodiment, the switch button 34 is electrically connected to the laser 29 and the fan 32 through wires, and the start and stop of the laser 29 and the fan 32 are controlled by the switch button 34.

[0049] The working principle of this invention is as follows: When in use, when the angle of the hair removal device main body 1 needs to be adjusted, start the bidirectional servo motor 7 to drive the main shaft 6 to rotate. Each time the main shaft 6 rotates one week driven by the bidirectional servo motor 7, the hair removal device main body 1 on the articulated rod 4 will rotate a fixed angle. At the same time, each time the main shaft 6 rotates one week, it will also drive the rotating arm 21 to swing clockwise and counterclockwise respectively. When the rotating arm 21 rotates counterclockwise, it will drive the engaging teeth 22 to engage with the third gear 12 and lock the third gear 12 after rotating a certain angle, that is, lock the hair removal device main body 1 after rotating a certain angle. When the rotating arm 21 rotates clockwise, it will drive the engaging teeth 22 to unlock from the third gear 12, that is, during the process of the main shaft 6 rotating one week, first the main shaft 6 will drive the rotating arm 21 to rotate clockwise to unlock the third gear 12, then the main shaft 6 drives the second gear 11 to rotate to drive the third gear 12 to rotate a certain angle to drive the hair removal device main body 1 to rotate a certain angle, and then the main shaft 6 drives the rotating arm 21 to rotate counterclockwise to rotate the third gear 12 a certain angle and then lock it. Thus, by driving the main shaft 6 to rotate a fixed angle each time by the bidirectional servo motor 7, the hair removal device main body 1 can be rotated a certain angle and then locked, so that when the hair removal device is in use, the user does not need to frequently adjust the body posture to adapt to the device, and the operation is convenient. In addition, during the use of the hair removal device, an air-cooling structure for cooling and dehumidifying the inside of the hair removal device main body 1 is also provided inside the hair removal device main body 1. The air-cooling structure includes heat dissipation fins 30 fixed inside the hair removal device main body 1. A water-cooling pipe 31 is inserted through the inside of the heat dissipation fins 30. The water-cooling pipe 31 is in contact with the surface of the laser 29. A fan 32 is fixed inside the hair removal device main body 1. Through the water-cooling pipe 31, water-cooling can be carried out for the laser 29 during operation, and at the same time, heat exchange is carried out by using the internal coolant in contact with the laser 29. The water-cooling pipe 31 can simultaneously transfer heat to the heat dissipation fins 30. Starting the fan 32 can perform air-cooling on the heat absorbed by the coolant inside the water-cooling pipe 31 and the heat dissipation fins 30, so that water-cooling and air-cooling can be carried out for the laser 29 during operation. At the same time, since the fan 32 is arranged on one side of the heat dissipation hole 33, when the hair removal device is in use, the humid water vapor is difficult to enter the inside of the hair removal device main body 1 through the heat dissipation hole 33 due to the wind force of the fan 32. In addition, the heat dissipated by the heat dissipation fins 30 and the water-cooling pipe 31 will also form a temperature difference on both sides of the heat dissipation hole 33, so that the water vapor entering the inside of the hair removal device main body 1 through the heat dissipation hole 33 can be dried by the hot air.

[0050] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
