[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The annular sealing ring of the existing laser hair growth device uses a slot structure to connect the inner and outer shells, which has the problem of insufficient connection, especially when the outer shell is subjected to force, the outer shell is prone to displacement at the connection; at the same time, the outer shell is a spherical shell structure with insufficient structural strength, and is prone to stress concentration and rupture when subjected to local force, such as being prone to rupture when accidentally dropped.

[0038] To solve the above technical problems, refer to Figure 3 and Figure 4 As shown, Figure 3 This is a top view of the laser hair growth device in the embodiment. Figure 4 for Figure 3 Cross-sectional view of section C.

[0039] This embodiment provides a laser hair growth device, comprising: a connecting ring 1, an inner shell 2, an outer shell 3 and a laser light source.

[0040] A first card slot 11 and a second card slot 12 are provided on the top of the connecting ring 1 . The first card slot 11 and the second card slot 12 are annular in shape, and the second card slot 12 is spaced apart from the periphery of the first card slot 11 .

[0041] The first card slot 11 and the second card slot 12 of the connecting ring 1 are different in size, wherein the larger second card slot 12 is completely outside the smaller first card slot 11 , with no intersection therebetween, and the second card slot 12 surrounds the first card slot 11 .

[0042] The bottom of the inner shell 2 is clamped to the inner side of the first clamping slot 11. The bottom of the inner shell 2 is the inner shell bottom 20.

[0043] The bottom of the outer shell 3 is the outer shell bottom 30, which is clamped to the inner side of the second card slot 12 and sleeved on the outside of the inner shell 2. The inner side of the outer shell 3 is circumferentially and spaced apart with a plurality of limiting columns 31, which extend to the outer shell bottom 30. The groove wall of the second card slot 12 is limited between the outer shell bottom 30 and the limiting columns 31, that is, the outer shell bottom 30 and the limiting columns 31 are limited on both sides of the groove wall of the second card slot 12.

[0044] A plurality of limiting posts 31 are provided at intervals along the inner circumference of the outer shell 3. The existence of these limiting posts 31, on the one hand, enhances the structural strength of the outer shell 3, and on the other hand, makes the connection between the outer shell 3 and the inner shell 2 tighter, reducing looseness and displacement caused by vibration or external force; moreover, the limiting posts 31 extend to the bottom 30 of the outer shell, and together with the groove wall of the second slot 12 form a limiting structure, which not only further fixes the position of the outer shell 3, but also ensures that the outer shell 3 is not easily deformed or displaced when subjected to external force.

[0045] The connection ring 1 of the laser hair growth device of the above technical solution connects the inner shell 2 and the outer shell 3 through the first card slot 11 and the second card slot 12 respectively to form a shell structure, wherein the limiting column 31 on the inner side of the outer shell 3 can not only disperse the stress when the outer shell 3 is locally stressed, reduce the risk of rupture, and improve the structural strength of the outer shell 3, but also cooperate with the bottom 30 of the outer shell to limit the groove wall of the second card slot 12 between the bottom 30 of the outer shell and the limiting column 31, so that the outer shell 3 is not easy to deflect, and the connection strength of the outer shell 3 is improved. It can be seen that the laser hair growth device of the above technical solution can improve the connection and structural strength of the shell structure, so that the outer shell 3 is not easy to deflect or rupture due to external force, and the durability of the product is improved.

[0046] Exemplarily, the inner shell 2 and the outer shell 3 are an integrally formed spherical shell.

[0047] Exemplarily, the limiting column 31 is provided on the inner side of the housing 3 by means of integral molding, which can enhance the structural strength of the housing 3 and disperse stress.

[0048] Exemplarily, the laser hair growth device includes a top cover 4, see Figure 1 and Figure 2 As shown, Figure 1 This is the first exploded view of the laser hair growth device in the embodiment. Figure 2 The top of the outer shell 3 is provided with an opening 32, and the top cover 4 is made of transparent material and covers the opening 32. In this way, the transparent top cover 4 can facilitate the observation of the components on the inner shell 2, such as the laser light source, and facilitate the disassembly and assembly of these components.

[0049] Exemplarily, the laser light source is an LED lamp flexible board 100, and is installed between the top cover 4 and the inner shell 2, such as being fixed to the top cover 4 or the inner shell 2 by screws, and the laser light source is irradiated on the head through the inner shell 2.

[0050] For example, see Figure 1 and Figure 4 As shown, the top cover 4 is sealed at the opening 32 in the following manner: the top cover 4 and the outer shell 3 are connected by screws 5 and buckles 40, and the buckles 40 and screws 5 are spaced and cross-arranged along the edge of the top cover 4. Among them, "interval" means that the buckles 40 and screws 5 are not closely adjacent, and there is a certain distance between them. This spacing arrangement helps to disperse the fixing force, so that the top cover 4 is more evenly stressed and the situation of excessive stress on a single point is reduced; and "cross arrangement" means that the buckles 40 and screws 5 are not arranged in rows separately, but staggered with each other. For example, a buckle 40 may be followed by a screw 5, and then another buckle 40, and so on. This cross arrangement method increases the diversity and stability of the fixation, so that the top cover 4 can have better resistance when subjected to external forces in different directions.

[0051] For example, see Figure 1 , Figure 5 and Figure 6 As shown, Figure 5 for Figure 4 A magnified view of area A in the middle. Figure 6 for Figure 4Enlarged view of the middle B area. The outer circumference of the inner shell 2 is provided with a plurality of connecting ears 21 at intervals, and the connecting ring 1 is provided with connecting posts 13 arranged in pairs with the connecting ears 21. The connecting ears 21 and the connecting posts 13 are connected by screws 5. The connecting ring 1 is provided with connecting posts 13 arranged in pairs with the connecting ears 21, which means that each connecting ear 21 can find a corresponding connecting post 13 for connection, ensuring the accuracy and stability of the connection. This design not only enhances the structural strength of the inner shell 2, but also provides a stable support point for the connection with the connecting ring 1; the connecting ears 21 are connected with the connecting posts 13 by screws, and this mechanical fixing method is both firm and reliable. The screw connection has the ability to withstand large tensile and shear forces, can effectively resist external shocks and vibrations, ensure that the connection between the inner shell 2 and the connecting ring 1 will not loosen or fail due to long-term use or the influence of the external environment, and this design also facilitates the assembly and disassembly of the equipment. When maintenance or replacement of parts is required, the inner shell 2 and the connecting ring 1 can be easily separated by simply unscrewing the screws, which greatly simplifies the maintenance process. At the same time, since the connecting ears 21 and the connecting posts 13 are arranged in pairs, the corresponding connecting points can be found quickly and accurately during assembly, thereby improving assembly efficiency.

[0052] For example, see Figure 5 and Figure 6 As shown, the connecting ring 1 is integrally connected with a limiting portion 14 between each connecting ear 21, the first slot 11 is a stopper, and is provided with a first slot wall 110, the bottom 20 of the inner shell is limited between the limiting portion 14 and the first slot wall 110, the first slot 11 is designed as a stopper, and is provided with a first slot wall 110. Such a structure provides precise limiting for the bottom 20 of the inner shell. When the bottom 20 of the inner shell is limited between the limiting portion 14 and the first slot wall 110, the position of the inner shell 2 in the device can be ensured to be accurate. Such limiting design helps to prevent the inner shell 2 from shifting or shaking during use, thereby ensuring the stability of the device and the consistency of the treatment effect.

[0053] For example, see Figure 5 and Figure 6 As shown, exemplarily, the second slot 12 is a stopper structure and has a second slot wall 120 .

[0054] For example, see Figure 5 and Figure 6As shown, the connection ring 1 includes a first convex wall 15 and a second convex wall 16, a first card slot 11 is provided on the first convex wall 15, a second card slot 12 is provided on the second convex wall 16, a receiving groove 17 is formed between the first convex wall 15 and the second convex wall 16, and the laser hair growth device includes a speaker 6, which is connected to the main board 8 for sound generation and is provided at the bottom of the receiving groove 17 through a buckle 40. In this way, the double convex wall design not only enhances the structural strength of the connection ring 1, but also forms a receiving groove 17 design. This receiving groove 17 not only provides additional space for the internal layout of the device, but is also cleverly used to install the speaker 6, which is provided at the bottom of the receiving groove 17 through a buckle 40. This installation method is simple and effective, ensuring the stability and sound generation effect of the speaker 6.

[0055] For example, see Figure 1 and Figure 2 As shown, for example, a mounting slot 33 is provided on the inner side of the housing 3, and the laser hair growth device includes a battery 7 and a mainboard 8 which are inserted into the mounting slot 33. This design fully considers the internal layout of the device and the convenience of component installation. The existence of the mounting slot 33 enables key components such as the battery 7 and the mainboard 8 to be firmly inserted into the housing 3, ensuring the stability and reliability of the device during operation. First, the battery 7 is inserted into the mounting slot 33. This installation method is not only convenient for positioning and fixing the battery 7, but also conducive to the electrical connection between the battery 7 and the mainboard 8. At the same time, the housing 3 plays a certain protective role on the battery 7, preventing the battery 7 from being subjected to external impact and damage. Secondly, as the core component of the laser hair growth device, the mainboard 8 is also crucial in its installation position. By fixing the mainboard 8 through the mounting slot 33, the close fit between the mainboard 8 and the housing 3 can be ensured, reducing looseness and displacement caused by vibration or external force. In addition, the electrical connection between the mainboard 8 and the battery 7 is also installed through the mounting slot 33, eliminating the need for screw fixing.

[0056] For example, see Figure 1 and Figure 2 As shown, the laser hair growth device includes a head cushion 9, which is arranged on the inner side of the connecting ring 1. In some embodiments, the head cushion 9 is made of PU and sponge by hot pressing one-piece molding process, and the back is fixed to the inner side of the connecting ring 1 by a nylon hook, which ensures comfortable wearing and convenient disassembly and replacement.

[0057] For example, see Figure 1 and Figure 2 As shown, the laser hair growth device includes a touch button 10, which is arranged in an installation cavity on the outside of the inner shell 2 and can be pushed by a spring in the installation cavity so that the touch button 10 is arranged toward the outside of the outer shell 3. The touch button 10 can be triggered by touching the outer shell 3, thus forming a hidden design. The touch button 10 is connected to the main board for controlling the operation of the laser hair growth device.

[0058] Exemplarily, long pressing the touch button 10 realizes the power on / off function; short pressing the touch button 10 realizes area switching control. The default starting mode is global lighting, and each treatment is automatically restored to the global lighting mode of front area lighting, rear area lighting, and global lighting after completion.

[0059] Exemplarily, the following settings are performed in the main board 8:

[0060] When the device is powered on: (1) If the power is sufficient, the treatment function will be automatically turned on when the helmet is put on, and the treatment will stop when the helmet is taken off (the timer for stopping treatment with the helmet will be kept for a single operation); (2) If the power is insufficient, the voice prompt will be given when the helmet is put on, indicating that the power is insufficient and the product cannot be used.

[0061] Exemplarily, the following settings are performed in the main board 8:

[0062] The product can continuously treat for 30 minutes, stop treating after 30 minutes, and automatically shut down after 5 seconds. It has a low-battery reminder function and will automatically shut down if not used for a long time (60 seconds). The laser lamp beads flash at a fixed frequency (10Hz±0.1Hz).

[0063] Exemplarily, the following settings are performed in the main board 8:

[0064] Set the voice reminder function: long press the button, voice prompt: power on, power off; low battery, voice prompt: low battery, please charge before use; wear it on your head, voice prompt: start treatment; take it off, voice prompt: pause treatment; 30 minutes are up, voice prompt: time is up and treatment is over, the device will shut down after 5 seconds; short press the button to switch areas, voice prompts the corresponding luminous areas: front area luminous, rear area luminous, global luminous.

[0065] Exemplarily, it also includes an indicator light connected to the main board 8, and the main board 8 is configured as follows:

[0066] Set the indicator light function: (1) When the device is powered on, ① the green light will be on when the battery is sufficient; ② the orange light will flash when the battery is insufficient. (2) When the device is running, ① the blue light will be on when the device starts treatment; ② the orange light will flash when the battery is insufficient. (3) When the device is charging, ① the orange light will be on when the device is charging; ② the green light will be on when the device is fully charged.
