Description

Technical Field

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

[0002] In the field of beauty equipment, the technological innovation of handheld laser hair removal devices has always revolved around user experience, safety, and functionality. Existing hair removal device designs still have significant deficiencies in waterproof performance, angle adjustment flexibility, and coordinated optimization of heat dissipation systems. These deficiencies are specifically reflected in the following aspects:

[0003] Traditional hair removal devices are susceptible to water vapor intrusion when used in humid environments or clean scenarios, causing circuit shorts or component damage. For example, some existing devices use a simple mesh heat dissipation design. Although the waterproof and breathable layer blocks water droplets, 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 requires open air ducts, but such designs will destroy the sealing and increase the risk of water ingress. For example, the waterproof heat dissipation structure of some existing devices achieves water vapor isolation through a combination of hydrophobic and hydrophilic membranes, but this is not integrated into the overall heat dissipation system of the hair removal device, resulting in limited heat dissipation efficiency.

[0004] In addition, most existing hair removal devices adopt a fixed-angle design, and users need to frequently adjust their body posture to adapt to the device, resulting in inconvenience in operation. For example, the adjustment component of a hair removal device with multi-angle adjustment disclosed in patent CN118615012B only supports limited angle rotation and lacks a multi-dimensional locking function. It is easy to cause angle deviation during the hair removal process due to accidental contact, affecting the accuracy of the light spot coverage; for example, the handheld laser hair removal device disclosed in patent CN118634030A mentions a rotating hub design, but it is mainly used for heat dissipation and airflow guidance, and does not involve an angle locking function.

[0005] To this end, we provide a waterproof, multi-angle lockable handheld laser hair removal device to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a waterproof, multi-angle lockable handheld laser hair removal device to solve the problem mentioned in the above background technology that traditional hair removal devices are easily intruded by water vapor when used in humid environments or clean scenes, resulting in circuit short circuits or component damage. In addition, most existing hair removal devices adopt a fixed-angle design, requiring users to frequently adjust their body posture to adapt to the device, resulting in inconvenient operation.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0010] The hair removal device body is also provided with an air cooling structure for dissipating heat and removing water vapor from the hair removal device body.

[0012] A waterproof, multi-angle lockable handheld laser hair removal device as described above: the linkage structure includes a first driven shaft, a third driven shaft, a fourth driven shaft and a rotating rod rotatably arranged on the additional housing; the rotating arm is fixed to the rotating rod; the first driven shaft and the second driven shaft are driven by a first gear mechanism, and the first driven shaft drives the second driven shaft to rotate synchronously when it rotates; the third driven shaft and the fourth driven shaft are driven by a second gear mechanism, and the third driven shaft drives the fourth driven shaft to rotate synchronously when it rotates; the fourth driven shaft and the rotating rod are driven by a swinging mechanism, and the fourth driven shaft drives the rotating rod to rotate reciprocatingly clockwise and counterclockwise when it rotates;

[0013] The main shaft and the first driven shaft and the third driven shaft are transmitted through an intermittent mechanism. 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 will not rotate.

[0014] In the waterproof, multi-angle lockable handheld laser hair removal device as described above, the first gear mechanism includes a first gear fixed to a first driven shaft, and the first gear is meshed with a second gear for transmission.

[0015] The waterproof multi-angle lockable handheld laser hair removal device as described above: the second gear mechanism includes a fourth gear fixed on the third driven shaft and a fifth gear fixed on the fourth driven shaft, and the fourth gear is meshed with the fifth gear.

[0018] As described above, a waterproof, multi-angle lockable handheld laser hair removal device: a limit assembly is further provided between the rotating arm and the additional shell when the rotating arm swings back and forth clockwise or counterclockwise, and the limit assembly includes a limit rod fixed on the rotating arm and an arc groove provided on the additional shell, and the limit rod is movably engaged in the arc groove.

[0019] As described above, a waterproof, multi-angle lockable handheld laser hair removal device: the air-cooling structure includes heat dissipation fins fixed inside the hair removal device body, a water-cooling tube is inserted through the heat dissipation fins, one end of the water-cooling tube is in contact with the surface of the laser mounted on the hair removal device body, a fan is fixed inside the hair removal device body and on one side of the heat dissipation fins, and a heat dissipation hole is opened on the shell of the hair removal device body and on the other side of the heat dissipation fins.

[0020] The waterproof, multi-angle lockable handheld laser hair removal device as described above: a switch button for controlling the start and stop of the laser and the fan is fixed on the main body of the hair removal device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the bidirectional servo motor is started to drive the main shaft to rotate, and while the main shaft rotates, it will drive the second driven shaft to rotate intermittently and intermittently drive the rotating arm to swing back and forth clockwise and counterclockwise. When the second driven shaft rotates, it will drive the second gear to rotate, and the rotation of the second gear will synchronously drive the third gear to rotate. The rotation of the third gear will drive the hinged rod to rotate and then drive the hair removal device body to rotate. Each time the bidirectional servo motor drives the main shaft to rotate one circle, it will drive the hair removal device body on the hinged rod to rotate a fixed angle. At the same time, each time the main shaft rotates one circle, it will also drive the rotating arm clockwise and counterclockwise. The first gear is rotated by the second shaft, and the second gear is rotated by the second shaft to rotate the third gear at a certain angle, and then the main body of the hair removal device is rotated by a certain angle, and then the main shaft drives the rotating arm to rotate counterclockwise to lock the third gear.

[0022] Therefore, the present invention drives the main shaft to rotate a fixed angle each time by a bidirectional servo motor, so that the hair removal device body can be rotated to a certain angle and then locked. Therefore, when using the hair removal device, the user does not need to frequently adjust the body posture to adapt to the device, and the operation is convenient. In addition, the hair removal device body is mechanically locked after the multi-angle adjustment, so that the angle of the hair removal device body will not be offset due to accidental contact after the angle is adjusted, thereby improving the stability of the hair removal device body after the angle adjustment.

[0023] In addition, the hair removal device of the present invention is further provided with an air-cooling structure for dissipating heat and removing water vapor from the interior of the hair removal device body. The air-cooling structure includes heat dissipation fins fixed inside the hair removal device body, a water-cooling pipe is inserted into the interior 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 removal device body. The water-cooling pipe can be used to water-cool the laser when it is running, and the internal coolant is used to contact the laser for heat exchange. The water-cooling pipe can simultaneously transfer heat to the heat dissipation fins. Starting the fan can perform air-cooling and heat dissipation on the coolant in the water-cooling pipe and the heat absorbed by the heat dissipation fins, so that the present invention can perform water-cooling and air-cooling heat dissipation when the laser is running. At the same time, because the fan is arranged on one side of the heat dissipation hole, when the hair removal device is used, humid water vapor is difficult to enter the interior of the hair removal device 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 interior of the hair removal device body through the heat dissipation hole is dried by hot air, thereby achieving the purpose of waterproofing. In addition, the present invention integrates the waterproof heat dissipation structure together, so that the heat dissipation and waterproofing effects are effectively improved.

The clockwise rotation of the rotating rod 20 drives the rotating arm 21 to rotate clockwise. When the rotating arm 21 rotates clockwise, it drives the latching tooth 22 to unlock from the third gear 12.

[0045] 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 is meshed with the second gear 11 for transmission.

[0048] In this embodiment, when the third driven shaft 13 rotates, it drives the fourth gear 18 to rotate. The engagement 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.

[0049] 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.

The protruding rod 24 is movably engaged with the inside of the limiting groove 26, which will drive the swing arm 25 to swing back and forth. When the swing arm 25 swings back and forth, it will drive the rotating rod 20 to rotate clockwise and counterclockwise. When the rotating rod 20 rotates clockwise and counterclockwise, it will drive the rotating arm 21 to rotate clockwise and counterclockwise, thereby driving the locking tooth 22 to rotate clockwise and counterclockwise.

The limit assembly includes a limit rod 28 fixed on the rotating arm 21 and an arc groove 27 opened on the additional shell 5. The limit rod 28 is movably engaged in the arc groove 27.

[0054] In this embodiment, the limiting rod 28 is movably engaged in the arc groove 27, so as to limit the reciprocating clockwise and counterclockwise rotation of the rotating arm 21, thereby ensuring the stability of the rotation and preventing position deviation during the rotation.

[0055] As a further solution of the present invention, the air-cooling structure includes a heat dissipation fin 30 fixed inside the hair removal device body 1, a water-cooling tube 31 is inserted through the heat dissipation fin 30, one end of the water-cooling tube 31 is in contact with the surface of the laser 29 installed on the hair removal device body 1, a fan 32 is fixed inside the hair removal device body 1 and on one side of the heat dissipation fin 30, and a heat dissipation hole 33 is opened on the shell of the hair removal device body 1 and on the other side of the heat dissipation fin 30.

[0056] In this embodiment, the laser 29 can be water-cooled and dissipated during operation through the water-cooling tube 31, and the internal coolant is in contact with the laser 29 for heat exchange.

Starting the fan 32 can perform air-cooling and heat dissipation on the coolant inside the water-cooling tube 31 and the heat absorbed by the heat dissipation fins 30. Therefore, the present invention can perform water-cooling and air-cooling heat dissipation during operation of the laser 29. 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, moist water vapor is difficult to enter the hair removal device 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 tube 31 will also form a temperature difference on both sides of the heat dissipation hole 33, so that the water vapor entering the hair removal device body 1 through the heat dissipation hole 33 is dried by hot air, thereby achieving the purpose of waterproofing. The waterproof heat dissipation structure is integrated together, so that the heat dissipation and waterproofing effects are effectively improved.

[0057] 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 body 1.

[0058] In this embodiment, the switch button 34 is electrically connected to the laser 29 and the fan 32 via wires, and the start and stop of the laser 29 and the fan 32 are controlled by the switch button 34 .

[0059] The working principle of the invention is as follows: when the angle of the hair removal device body 1 needs to be adjusted during use, the bidirectional servo motor 7 is started to drive the main shaft 6 to rotate. Each time the bidirectional servo motor 7 drives the main shaft 6 to rotate one circle, the hair removal device body 1 on the hinged rod 4 is driven to rotate a fixed angle. At the same time, each time the main shaft 6 rotates one circle, the rotating arm 21 is driven to deflect once clockwise and counterclockwise respectively. The counterclockwise rotation of the rotating arm 21 drives the latch 22 to engage with the third gear 12 and lock the third gear 12 after rotating a certain angle. That is, the hair removal device body 1 is locked after rotating a certain angle, and the rotating arm 21 is driven clockwise. When the needle rotates, it drives the latch 22 to unlock the third gear 12. That is, during the process of the main shaft 6 rotating one circle, the main shaft 6 will first 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 and drive the third gear 12 to rotate a certain angle to drive the hair removal device body 1 to rotate a certain angle. 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. Therefore, the bidirectional servo motor 7 drives the main shaft 6 to rotate a fixed angle each time, which can make the hair removal device body 1 rotate a certain angle and then lock it, so that the hair removal device can be used. When using the device, 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, the hair removal device body 1 is further provided with an air-cooling structure for dissipating heat and removing water vapor from the internal body 1 of the hair removal device. The air-cooling structure includes a heat dissipation fin 30 fixed to the inside of the hair removal device body 1, and a water-cooling pipe 31 is inserted through the inside of the heat dissipation fin 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 body 1. The water-cooling pipe 31 can be used to water-cool the laser 29 during operation, and the internal coolant is used to contact the laser 29 for heat exchange. The water-cooling pipe 31 can At the same time, the heat is transferred to the heat dissipation fins 30. Starting the fan 32 can perform air cooling and heat dissipation on the coolant in the water-cooling tube 31 and the heat absorbed by the heat dissipation fins 30, so that the laser 29 can be water-cooled and air-cooled when it is running. 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, moist water vapor is difficult to enter the hair removal device 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 tube 31 will also form a temperature difference on both sides of the heat dissipation hole 33, so that the water vapor entering the hair removal device body 1 through the heat dissipation hole 33 is dried by the hot air.

[0060] 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.
