Technical Field

[0001] The present invention relates to the technical field of laser hair growth equipment, and in particular to a hair growth device based on carbon dioxide laser technology and a use method thereof. Background Art

[0002] Hair diseases are common clinical diseases, the most common of which are hair loss, baldness, dry hair and gray hair. With the increasing awareness of beauty, people have higher requirements for hair health. At present, through the combined use of carbon dioxide laser and Shengfaling Liniment, with the CO2 single-pulse laser output power of 15W and the action time of 0.05 seconds as the operating parameters, the physical stimulation of the laser and the nourishing effect of the traditional Chinese medicine of Shengfaling Liniment are used to promote the blood circulation of the scalp and the regeneration and repair of hair follicles, so as to achieve the purpose of treating hair loss.

[0005] 1. This solution achieves scalp stimulation through the cooperation of a helmet and a laser head. However, since the area of ​​hair loss on each user's head varies, this solution cannot adjust the range of laser irradiation according to actual conditions, causing healthy scalp areas to be irradiated by the laser, which may cause scalp damage.

[0006] 2.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] Example 1: Reference Figure 1 and Figure 2 , a hair growth instrument, which is used in the field of laser hair growth equipment, mainly includes a carbon dioxide laser instrument 1, which is fixed on the top of a fixing seat 2. The fixing seat 2 is designed to be stable and can ensure the stability of the laser instrument during use. Above the fixing seat 2, a second rotating arm 6 is provided, and an arc arm 11 is connected to the bottom of the rotating arm. There is a headgear ring 12 rotating at the two bottom ends of the arc arm 11. The headgear ring 12 is designed to fit tightly and fit on the user's head to ensure the accuracy of the treatment process.

[0049] Reference Figure 3 and Figure 5 Inside the arc-shaped arm 11, there is an arc-shaped mounting plate 16, which can slide inside the arc-shaped arm 11. A plurality of laser heads 17 are fixed to the bottom of the arc-shaped mounting plate 16, and these laser heads 17 are used to irradiate lasers on the user's head to promote hair growth.

[0050] Reference Figure 3 and Figure 5 In order to control the irradiation area of ​​the laser head 17, an arc-shaped shading plate 25 is also provided in the arc-shaped arm 11. The bottom of the shading plate extends into the first annular groove 28 of the head ring 12, and the range of laser irradiation can be controlled by adjusting the position of the shading plate. In addition, a track groove 30 is also provided in the arc-shaped arm 11, and a sliding block 31 is slidably connected in the track groove 30. An arc-shaped wiper 36 is provided below the sliding block 31 for applying the hair growth ointment.

[0051] Reference Figure 1 and Figure 2 The adjustment structure includes a steering ball 3, a first rotating arm 4, a rotating shaft 5 and a second rotating arm 6. The steering ball 3 rotates on the top of the fixed seat 2, and its top is connected to the first rotating arm 4. The rotating shaft 5 runs through the first rotating arm 4, and the second rotating arm 6 is sleeved on the rotating shaft 5 and can rotate thereon. The other end of the second rotating arm 6 is connected to the driving motor 9 through the rotating column 8, and the output shaft of the driving motor 9 is connected to the driving rod 10, and the bottom end of the driving rod 10 is fixed to the arc arm 11. By rotating the driving motor 9, the arc arm 11 can be driven to rotate in the horizontal and vertical directions, thereby adjusting the position of the laser head 17.

[0052] Reference Figure 3 , Figure 5 , Figure 7 and Figure 8The treatment structure includes an arc groove 14 arranged at the bottom of the arc arm 11, and an arc mounting plate 16 is slidably arranged in the groove. An arc rod 15 is fixed in the arc mounting plate 16, one end of the arc rod 15 extends into the arc arm 11, and the other end extends into the second annular groove 29. A reciprocating screw rod 18 is provided at one end of the arc arm 11, and its bottom end also extends into the second annular groove 29. A first gear 19 is fixed on the reciprocating screw rod 18, and the gear is intermittently meshed with the incomplete gear ring 20 in the headgear ring 12. The inner walls on both sides of the U-shaped seat 21 that are away from each other are provided with clearance grooves 22, and the same sliding rod 23 is slidably arranged on the inner wall on one side of the two clearance grooves 22 that are away from each other, and one end of the sliding rod 23 rotates to penetrate the arc rod 15, and the lifting and lowering of the U-shaped seat 21 can drive the arc rod 15 to lift and lower. When the arc arm 11 rotates, the incomplete gear ring 20 drives the reciprocating screw 18 to rotate, and then drives the arc rod 15 and the arc mounting plate 16 to rise and fall through the cooperation of the U-shaped seat 21 and the sliding rod 23, so as to realize the irradiation of the laser head 17 at different positions of the head.

[0053] Specifically, when the driving motor 9 drives the arc-shaped arm 11 to rotate, the laser head 17 will follow the movement of the arc-shaped arm 11 to irradiate the head. Due to the intermittent meshing characteristics of the first gear 19 and the incomplete gear ring 20, the laser head 17 will irradiate different positions of the head every time it rotates, avoiding possible damage caused by irradiating one position for a long time.

[0054] Reference Figure 3-Figure 6 The shielding structure includes a U-shaped frame 24, which is slidably mounted on the outer wall of the arc-shaped arm 11 to ensure that the U-shaped frame 24 can move smoothly along the arc-shaped arm 11. Then, an arc-shaped shading plate 25 is fixedly installed inside the U-shaped frame 24. The size and position of the arc-shaped shading plate 25 must be precisely designed to ensure that the laser beam emitted by the laser head 17 can be effectively blocked. A through hole is opened at the top of the U-shaped frame 24, and a pin rod 26 is slidably installed through it. A first tension spring 27 is mounted on the outer wall of the pin rod 26, and the top end of the first tension spring 27 is fixedly connected to the outer wall of the pin rod 26, while the bottom end of the first tension spring 27 is fixedly connected to the top of the U-shaped frame 24. In this way, the first tension spring 27 is always in a stretched state, providing an inward elastic force for the pin rod 26. On the outer wall of the arc-shaped arm 11, a plurality of equally spaced positioning grooves 46 are designed. When the pin rod 26 moves inwardly under the action of the first tension spring 27 , the end of the pin rod 26 will be stuck in any one of the positioning grooves 46 , thereby achieving braking of the U-shaped frame 24 and the arc-shaped sunshade 25 .

[0055] Specifically, when the position of the arc shading plate 25 needs to be adjusted, the pin 26 only needs to be pulled outward to disengage it from the current positioning groove 46, and then the arc shading plate 25 is driven to move along the arc arm 11 by sliding the U-shaped frame 24 until the arc shading plate 25 is in the desired position, and then the pin 26 is released to allow it to be re-engaged in the new positioning groove 46.

[0056] The arc-shaped light shielding plate 25 can block part of the laser head 17 by adjusting its position in the arc-shaped arm 11, thereby controlling the irradiation area of ​​the laser. This design allows the user to adjust the irradiation range as needed to improve the treatment effect.

[0057] Reference Figure 3 The design of the smearing structure is as follows: a through hole is opened on the sliding block 31, and a screw rod 32 is installed by sliding through the through hole. The bottom end of the screw rod 32 is fixedly connected to the top of the arc wiping plate 36 to ensure that the arc wiping plate 36 can move with the up and down movement of the screw rod 32. Above the sliding block 31, a fixed ring 33 is slidably installed, and a second tension spring 35 is fixedly connected between the bottom of the fixed ring 33 and the top of the sliding block 31. The second tension spring 35 is sleeved on the outer wall of the screw rod 32 to provide an upward elastic force for the screw rod 32. At the top of the fixed ring 33, a connecting nut 34 is rotated, and the nut 34 is threadedly sleeved on the outer wall of the screw rod 32. By rotating the nut 34, the extension length of the screw rod 32 can be controlled, and then the distance between the arc wiping plate 36 and the head can be adjusted. When the nut 34 rotates downward, the screw rod 32 drives the arc wiping plate 36 to move downward until the arc wiping plate 36 hits the user's head. At this time, the nut 34 controls the extension distance of the screw rod 32, and thus controls the pressure exerted by the second tension spring 35 on the arc-shaped wiper plate 36 toward the head.

[0058] Specifically, when the arc arm 11 rotates, since the arc plate 36 has maintained a certain contact pressure with the head through the second tension spring 35, the rotation of the arc arm 11 will drive the arc plate 36 to rotate on the surface of the head, thereby evenly applying the hair growth ointment applied on the arc plate 36 to the hair loss area.

[0059] Reference Figure 3 In order to increase the comfort of the user wearing the headgear ring 12, a rubber gasket ring 13 is fixedly installed on the inner wall of the headgear ring 12. The material of the rubber gasket ring 13 is soft and has a certain elasticity, which can fit the contour of the user's head, reduce the pressure of the headgear ring 12 on the head, and thus improve the wearing comfort.

[0060] Reference Figure 2 In order to keep the angle between the first rotating arm 4 and the second rotating arm 6 unchanged after the rotation, we fixedly penetrate the damping bearings 7 inside the two rotating arms. Specifically, the damping bearings 7 are firmly installed at appropriate positions of the rotating arms, so that the two ends of the rotating shaft 5 can penetrate the two damping bearings 7 respectively.

[0061] Specifically, when the rotating shaft 5 drives the first rotating arm 4 and the second rotating arm 6 to rotate to a desired angle, the damping mechanism inside the damping bearing 7 will work to prevent the rotating arm from further rotating freely, thereby keeping the angle between the two stable. This design helps to ensure that the position of the laser emitter head can be accurately and stably adjusted and fixed during the use of the hair growth device.

[0062] In summary, the hair growth device of the present invention realizes precise irradiation and drug application to different positions of the head through careful structural design and reasonable functional layout, providing users with an efficient and safe hair growth treatment experience.

[0063] Example 2: Reference Fig. 9 and Fig.10 , improved on the basis of Example 1: First, two base plates 39 are fixedly installed on one side of the arc-shaped arm 11, and the two base plates 39 are rotationally connected through a driving shaft 40. A winding roller 41 is fixed on the outer wall of the driving shaft 40, and a pull rope 42 is wound around the outer wall of the winding roller 41. One end of the pull rope 42 extends into the track groove 30 and is fixedly connected to one side of the sliding block 31 sliding in the track groove 30. At the same time, a third tension spring 37 is fixed to the other side of the sliding block 31, and the end of the third tension spring 37 away from the winding roller 41 is fixedly connected to one side of the inner wall of the track groove 30. In this way, when the winding roller 41 reels or releases the pull rope 42, it will cooperate with the elastic force of the third tension spring 37 to control the movement of the sliding block 31 in the track groove 30.

[0064] In order to realize the rotation of the winding roller 41 when the arc arm 11 rotates, we rotatably connect a worm 43 on one side of the arc arm 11 through the base. The bottom end of the worm 43 extends into the second annular groove 29, where a second gear 44 is fixed. The second gear 44 is intermittently meshed with the incomplete gear ring 20, which means that during the rotation of the arc arm 11, the second gear 44 will periodically contact the incomplete gear ring 20 and transmit power. At the same time, one end of the drive shaft 40 rotates through one of the base plates 39, and a worm wheel 45 is fixedly sleeved on its outer wall. The worm wheel 45 is meshed with the worm 43, so when the worm 43 rotates, it will drive the worm wheel 45 and the drive shaft 40 and winding roller 41 connected thereto to rotate.

[0065] Specifically, during the rotation of the arc-shaped arm 11, since the worm 43 revolves with the arc-shaped arm 11 and rotates with the cooperation of the incomplete gear ring 20 and the second gear 44, whenever the second gear 44 meshes with the incomplete gear ring 20, the worm 43 will be subjected to a driving torque and rotate. This rotation is transmitted to the drive shaft 40 and the winding roller 41 through the worm gear 45, so that the winding roller 41 winds up the pull rope 42, thereby pulling the sliding block 31 to move to one side in the track groove 30. At the same time, the third tension spring 37 is stretched in this process. Through such a design, every time the arc-shaped arm 11 rotates one circle, the sliding block 31 and the arc-shaped wiper plate 36 connected thereto can be driven to move a certain distance in the track groove 30 through the linkage mechanism of the worm 43, the worm gear 45 and the winding roller 41. This movement process can automatically and evenly apply the hair growth agent to the hair loss area, thereby improving the treatment effect and user experience.

[0066] In addition, in order to optimize the moving path of the pull rope 42 and ensure its smooth sliding in the track groove 30, we also rotatably connect the guide roller 38 in the track groove 30. The bottom of the guide roller 38 touches the pull rope 42 to guide the pull rope 42, reduce the friction between the pull rope 42 and the inner wall of the track groove 30, and improve the operation efficiency and stability of the overall mechanism.

[0067] A method for using a hair growth device based on carbon dioxide laser technology comprises the following steps:

[0068] S1. When in use, the headband ring 12 is put on the user's head, and the arc-shaped shading plate 25 is adjusted to block the corresponding laser head 17 according to the area of ​​hair loss on the top of the user's head; during specific operation, the pin rod 26 is pulled outward, the pin rod 26 is released from the cooperation with the positioning groove 46, and the arc-shaped shading plate 25 is driven to move along the arc-shaped arm 11 through the U-shaped frame 24 to control the arc-shaped shading plate 25 to block the laser head 17. After the adjustment is completed, the pin rod 26 cooperates with the positioning groove 46 under the tension of the first tension spring 27 to brake the U-shaped frame 24 again;

[0069] S2, the driving motor 9 drives the driving rod 10 and the arc-shaped arm 11 to rotate, and the arc-shaped arm 11 drives multiple laser heads 17 to rotate through the arc-shaped mounting plate 16, which is used to emit laser to the user's head. In order to enable the hair loss positions to be irradiated by the laser, the arc-shaped mounting plate 16 is driven to move in the arc-shaped groove 14 when the arc-shaped arm 11 rotates, so that the laser head 17 can perform laser irradiation at different positions; in specific operation, the driving rod 10 drives the arc-shaped arm 11 to rotate, and the arc-shaped arm 11 drives the reciprocating screw rod 18 at its bottom to rotate in the second annular groove 29, and the first gear 19 It is intermittently meshed with the incomplete toothed ring 20, so after the arc-shaped arm 11 and the reciprocating screw 18 rotate one circle, the laser head 17 irradiates the head one circle, the first gear 19 is meshed with the incomplete toothed ring 20, and the cooperation between the incomplete toothed ring 20 and the first gear 19 drives the U-shaped seat 21 to rise and fall, and then the arc-shaped rod 15 is driven to rise and fall a certain distance through the cooperation of the clearance groove 22 and the sliding rod 23, so that the arc-shaped mounting plate 16 can be controlled to move, thereby controlling the laser head 17 to irradiate different hair loss positions, avoiding the laser head 17 irradiating one position for a long time to cause harm to the user;

[0070] S3. After a certain period of time after laser irradiation, apply a proper amount of hair growth agent to the hair loss area, rotate the nut 34 to drive the screw rod 32 and the arc-shaped wiper plate 36 to move downward, so that the arc-shaped wiper plate 36 contacts the user's head, and the nut 34 controls the extension distance of the screw rod 32 to control the pressure applied by the second tension spring 35 to the head by the arc-shaped wiper plate 36, so that when the arc-shaped arm 11 rotates, the arc-shaped wiper plate 36 is driven to rotate, and the hair growth agent is evenly applied to the hair loss area;

[0071] S4. The sliding block 31 is pulled to one side by the pull rope 42 to change the application position of the arc-shaped wiping plate 36. During the specific operation, the arc-shaped arm 11 drives the worm 43 to work. Every time the arc-shaped arm 11 rotates one circle, the second gear 44 will mesh with the incomplete gear ring 20. The cooperation between the incomplete gear ring 20 and the second gear 44 drives the worm 43 to rotate. The worm 43 drives the driving shaft 40 and the winding roller 41 to rotate through the worm gear 45. The winding roller 41 rewinds the pull rope 42 to pull the sliding block 31 to one side. The third tension spring 37 is in a stretched state at this time. Therefore, one rotation of the arc-shaped arm 11 can drive the arc-shaped wiping plate 36 to move a certain distance, thereby automatically and evenly applying the hair growth ointment to the hair loss area.

[0072] However, as is well known to those skilled in the art, the working principles and wiring methods of the laser head 17 and the drive motor 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
