Description

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 massage 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 are equipped with vibration devices, which massage the scalp through vibration to promote blood circulation and relieve scalp stress. However, the vibration effect of such products is often not ideal, and the vibration transmission is uneven, which affects the use effect and user experience.

[0004] In addition, some hair care combs use low-energy laser therapy (LLLT), which irradiates the scalp with specific wavelength laser to promote the activity of hair follicle cells and improve 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 method of the low-energy laser lamp is complicated, which is not conducive to production and maintenance. SUMMARY

[0015] The vibration motor transmits the vibration to the comb tooth through the support, and the user can feel the vibration massage effect when combing the hair, which helps to relax the scalp, reduce the stress and fatigue of the scalp.

[0016] The handle part is provided with a key, and the power switch can be conveniently controlled through the key, so that the on-off operation of the hair care comb is realized, and the use is simple and convenient.

[0017] The lamp plate, the control board and the main control board are electrically connected with the battery respectively, through the modular design, the assembly process is simplified, the production efficiency is improved, and the manufacturing cost is reduced.

[0018] The comb tooth part transmits the vibration uniformly, so that the user can feel appropriate vibration during use, and the comfort degree of use is increased.

[0023] During product use, if a fault occurs, the plug-in structure makes it easier to disassemble and replace the lamp panel, control panel, and main control panel. Workers only need to remove the faulty component and plug in a new one, greatly facilitating maintenance and repair work.

[0024] This plug-in method embodies the advantages of modular design, allowing each module to be produced and tested independently, ensuring the quality of each module. At the same time, modular design facilitates product upgrades and functional expansion, allowing new functions to be achieved by replacing or adding corresponding modules.

[0025] The application of the plug-in structure reduces complex processes such as welding and wiring, reducing labor and time costs. At the same time, modular design allows components to be mass-produced, further reducing production costs.

[0026] Due to the simplicity of the plug-in structure, users do not need to worry about internal circuit connection problems during use, making the product more stable and reliable. In addition, modular design can also provide personalized customization services, allowing users to choose different functional modules according to their needs, enhancing user experience.
