TECHNICAL FIELD

[0001] The utility model relates to a hair care comb. BACKGROUND

[0002] The main function of the hair care comb on the market is to keep the scalp and hair clean by combing the hair. However, the traditional hair care comb has the limitation of single function and cannot effectively improve the scalp health and promote hair growth. Therefore, some hair care combs with phototherapy function have gradually appeared in the prior art, but these products still have some problems in practical application.

[0003] For example, some hair care combs adopt low-energy laser therapy (LLLT) to promote the activity of hair follicle cells by irradiating the scalp with laser of specific wavelength, thereby improving the scalp health. Although this technology is effective in theory, the existing product design is complex and the structure is large, which makes it difficult to realize portability and daily use. At the same time, the installation mode of the low-energy laser lamp is relatively cumbersome, which is not conducive to production and maintenance. SUMMARY

[0009] The low-energy red light emitted through the light transmission holes directly irradiates the scalp, which can promote the blood circulation of the scalp, increase the blood flow and improve the health condition of the hair follicles.

[0010] The LLLT low-energy red light can stimulate the hair follicle cells and improve the cell activity, thereby promoting the growth of the hair and increasing the hair density.

[0011] The handle part is provided with a button, through which the power switch can be conveniently controlled to realize the switching operation of the hair care comb, and the use is simple and convenient.

[0012] The lamp plate, the control plate and the main control plate are electrically connected with the battery, the modular design is adopted to simplify the assembly process, improve the production efficiency and reduce the manufacturing cost.

[0013] The technical measures can also be used to solve the problems.

[0014] Further, the lamp plate is provided with a first conductive plug-in part, the control plate is provided with a second conductive plug-in part, the main control plate is provided with a third conductive plug-in part corresponding to the position of the first conductive plug-in part, and the main control plate is provided with a fourth conductive plug-in part corresponding to the position of the second conductive plug-in part, the first conductive plug-in part and the third conductive plug-in part are plugged together, and the second conductive plug-in part and the fourth conductive plug-in part are plugged together, so that the lamp plate, the control plate and the main control plate are electrically connected.

[0015] The conductive plug-in parts of the lamp plate, the control plate and the main control plate are designed as plug-in structures, so that workers only need to plug the corresponding conductive plug-in parts together during the assembly process, without the need for complex welding and wiring operations, thereby greatly simplifying the production and assembly process and improving the production efficiency.

[0016] The plug-in structure can provide reliable electrical connection, reduce circuit failure caused by poor welding or loose wiring, improve the stability and reliability of the product, and prolong the service life of the product.

Workers only need to pull out the faulty components and plug in new components, which greatly facilitates maintenance and repair work.

[0018] This plug-in method embodies the advantages of modular design, so that each module can be independently produced and tested to ensure the quality of each module. At the same time, the modular design facilitates the upgrading and functional expansion of the product, and new functions can be realized by replacing or adding corresponding modules.

[0019] The application of the plug-in structure reduces the complex processes such as welding and wiring, and reduces the labor and time costs. At the same time, the modular design enables the components to be mass-produced, further reducing the production cost.

[0022] The distance sensing device can monitor in real time whether the comb teeth are close to the scalp, and automatically control the start and stop of the LLLT low-energy red light according to the detection results, making the red light therapy more accurate and intelligent, avoiding the tedious manual operation and improving the convenience of user use.

[0023] When the distance sensing device detects that the comb teeth are not close to the scalp, it will automatically turn off the LLLT low-energy red light, thereby saving battery energy, extending battery life, and reducing unnecessary energy waste.

[0024] By monitoring the distance between the comb teeth and the scalp, it can ensure that the red light only works in the correct position, avoiding direct exposure of red light to sensitive areas such as the eyes, and improving product safety.

[0025] The distance sensing device ensures that the LLLT low-energy red light lamp only works when the comb teeth touch the scalp, ensuring that the red light can effectively act on the scalp and hair follicles, thereby improving the therapeutic effect of red light therapy.

[0026] Since the distance sensing device can control the working state of the red light, the red light is prevented from working unnecessarily for a long time, thereby extending the service life of the red light and the entire hair care comb.
