Description

Technical Field

[0001] This utility model belongs to the technical field of laser hair removal devices, specifically, it relates to a laser hair removal instrument. Background Technology

[0002] Laser hair removal devices work based on the principle of selective photothermolysis. Therefore, during actual use, it is necessary to maintain a certain distance between the laser hair removal device and the skin to avoid burning-like marks on the skin surface due to excessive distance. However, existing laser hair removal devices mainly rely on manual control of the distance between the device and the skin by the operator. This can easily lead to skin burns due to being too close or unsatisfactory hair removal results due to being too far away. In addition, while some laser hair removal devices have a baffle ring installed at the laser emitter to control the distance, the distance between the laser hair removal device and the skin varies depending on the hair density and follicle depth when removing hair from different parts of the body. A fixed distance control is difficult to adapt to the appropriate distance between the laser hair removal device and the skin when removing hair from different parts of the body.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] Example 1

[0025] Please see Figures 1-6 The laser hair removal device shown in the figure includes a body 101 and a display screen 102 and a laser emission port disposed at both ends of the body 101. A handle 103 is provided on one side of the body 101, and a control button 104 is provided at the handle 103. It also includes a control component disposed on the body 101 for controlling the distance between the laser emission port and the skin.

[0026] The control component includes a fixing ring 201 sleeved on the side wall of the body 101 near the launch port. The fixing ring 201 is matched with the side wall of the body 101 and is fixed to the body 101 by the abutment of multiple bolts 202. The side of the fixing ring 201 away from the handle 103 is connected to a control ring 203 through an adjustment component. The side of the control ring 203 away from the fixing ring 201 is rotatably connected to multiple control balls 204.

[0027] It should be noted here that by controlling the settings of the components, burn-like marks on the skin surface can be avoided due to excessively close proximity, thereby improving the safety of using the laser hair removal device.

[0028] It is worth noting that the specific structure and working principle of laser hair removal devices are already known to those in the field, and will not be elaborated upon here.

[0029] Please see Figure 2 , Figure 3 and Figure 5The adjustment assembly shown in the figure includes multiple adjustment tubes 301 disposed on the side of the fixed ring 201 near the control ring 203. Each adjustment tube 301 is slidably connected to an adjustment rod 302. One end of each adjustment rod 302 is connected to the control ring 203. Each adjustment tube 301 has a strip hole 303 on its side wall. Each strip hole 303 is slidably connected to a strip plate 304. One end of each strip plate 304 is connected to the adjustment rod 302. Each adjustment tube 301 is provided with a limiting assembly for limiting the adjustment rod 302.

[0030] It should be noted here that by adjusting the settings of the components, the distance between the laser emitter and the skin can be adjusted according to the differences in hair density and hair follicle depth in different parts of the body, thereby improving the flexibility of laser emission distance adjustment and the accuracy of distance control.

[0031] Please see Figures 2-6 The limiting component shown in the figure includes a through hole 501 opened on the side wall of the adjusting tube 301. The through hole 501 is connected to a T-shaped rod 502 through a guide component. The side wall of the adjusting rod 302 is provided with multiple limiting holes 503. Each limiting hole 503 is matched with the T-shaped rod 502. The adjusting tube 301 is provided with a driving component for driving the T-shaped rod 502.

[0032] It should be noted here that the limiting component is used to limit and lock the adjusting rod 302, thereby ensuring the positional stability of the control ring 203.

[0033] Please see Figure 5 and Figure 6 The guide assembly shown in the figure includes a guide groove 601 formed on the side wall of the T-shaped rod 502, a guide plate 602 slidably connected to the guide groove 601, and one end of the guide plate 602 connected to the inner wall of the through hole 501.

[0034] It should be noted here that the guide assembly is used to guide and limit the movement of the T-bar 502.

[0035] Working principle: When using a laser hair removal device, first hold the handle 103 and adjust the parameters through the display screen 102. After adjusting the parameters, align the laser generator of the device 101 with the hair removal area. When the laser generator is aligned with the hair removal area, the multiple control balls 204 on one side of the control ring 203 come into contact with the skin. The distance between the control ring 203 and the device 101 is used to control the distance between the laser generator and the skin, thereby avoiding burn-like marks on the skin surface due to excessive distance, thus improving the safety of using the laser hair removal device.

[0036] Therefore, under the distance control of the control ring 203, the control ball 204 can be rolled on the skin, and the laser generator inside the body 101 can emit laser light to the skin. When the laser shines on the skin surface, the laser energy is absorbed by the melanin particles in the hair and converted into heat energy. This heat energy will cause the temperature of the hair follicle to rise sharply, generally reaching about 70°C. The key structures such as stem cells in the hair follicle will be destroyed, thereby causing the hair to lose its ability to regenerate, thus achieving the effect of hair removal.

[0037] When performing hair removal on different parts of the body, due to differences in hair density and follicle depth, it is necessary to adjust the distance between the control ring 203 and the machine body 101. During the adjustment process, the driving component first releases the limit on the adjustment rod 302, and then the extension and retraction of the adjustment rod 302 realizes the adjustment of the distance between the control ring 203 and the laser emitter of the machine body 101. This facilitates the adjustment of the distance between the laser emitter and the skin according to the differences in hair density and follicle depth in different parts of the body, thereby improving the flexibility of laser emission distance adjustment and the accuracy of distance control.

[0038] Example 2

[0039] Please see Figure 3 and Figure 4 This embodiment further illustrates Example 1. The driving assembly shown in the figure includes a driving ring 701 sleeved on the side wall of each adjusting tube 301. Multiple driving plates 702 are hinged to the side of the driving ring 701 near the T-shaped rod 502. One end of each driving plate 702 is hinged to the side wall of the T-shaped rod 502. A spring 703 is sleeved on the side wall of each T-shaped rod 502. The two ends of the spring 703 are respectively connected to the adjusting tube 301 and the side wall of the T-shaped rod 502.

[0040] It should be noted that, through the configuration of the drive assembly, when it is necessary to adjust the distance between the control ring 203 and the laser emitting end of the body 101, pushing the drive ring 701 causes the drive plate 702 to rotate. Then, under the pushing force and the guiding action of the guide assembly, each T-shaped rod 502 moves out of the limiting hole 503, thereby releasing the limitation on the adjusting rod 302. At this time, the distance between the control ring 203 and the laser emitting end can be adjusted by extending and retracting the adjusting rod 302. After the adjustment is completed, the push on the drive ring 701 is released. At this time, under the elastic action of the spring 703, each T-shaped rod 502 will be pushed into the limiting hole 503, thereby realizing the limitation on the T-shaped rod 502 again.
