Description

Technical Field

[0001] This invention relates to the field of hair growth device technology, specifically a multifunctional lightweight hair growth device based on a laser component. Background Technology

[0002] The multifunctional lightweight hair growth device based on laser components is an intelligent hair growth device that integrates laser biostimulation technology with a portable wearable design. Its core definition is: using a head-mounted structure as a carrier, it outputs low-energy lasers of a specific wavelength through a built-in laser emitting component, which acts on the hair follicle tissue of the human scalp. Combined with intelligent control and adaptive wearable design, it can activate hair follicle activity, improve scalp microcirculation, and thus awaken resting hair follicles, promote hair growth, and improve hair loss problems. It is a portable intelligent wearable device.

[0003] Most current hair regrowth devices only stimulate the scalp through a single laser method. This single-mechanism design has significant flaws, resulting in poor hair regrowth effects and failing to meet users' actual needs for hair regeneration. First, the effects of single laser stimulation are limited. It can only achieve photobiological activation of hair follicles, but it cannot solve the problems of hair regrowth obstacles caused by an unfavorable scalp environment. For example, some people with hair loss have problems such as excessive scalp oil secretion, thickened stratum corneum, and bacterial imbalance. These problems can block the opening of hair follicles, hindering the effective penetration of laser energy and depriving hair follicles of the nutrients needed for growth. Even with continuous laser stimulation, hair follicles cannot successfully enter the growth phase, thus greatly reducing the effectiveness of hair regrowth. Summary of the Invention

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a multifunctional lightweight hair growth device based on a laser component, which has the following beneficial effects: 1. This multifunctional lightweight hair growth device based on laser components, during use, the controller's power module supplies power to the first and second flexible circuit boards. The second flexible circuit board drives several laser beads to emit low-energy lasers and several low-frequency ultrasonic transducers to work, while simultaneously driving micro-current generating electrode plates to generate a weak and safe current. The miniature PTC heater transfers heat to the flexible heat-conducting layer through a heat-conducting sleeve. The flexible heat-conducting layer evenly diffuses heat to the scalp. Several temperature sensors collect temperature data in real time and transmit it to the first flexible circuit board through wires, which then feeds back to the controller to achieve precise temperature control. The heat-conducting strip outside the heat-conducting sleeve can enhance the uniformity of heat conduction, and the thermal grease on the inner wall of the heat-conducting sleeve, together with the thermal protrusions, improves the thermal conductivity efficiency of the miniature PTC heater. This invention solves the problem of poor hair growth effect caused by the single laser method in existing hair growth devices. The photobiological stimulation of the laser lamp beads, the unblocking of hair follicle channels by the low-frequency ultrasonic transducer, the oil regulation and metabolic activation by the microcurrent generating electrode, and the blood circulation promotion by the micro PTC heater form a synergistic effect, which improves the scalp environment and activates hair follicles from multiple dimensions. The cooperation of the temperature sensor and controller ensures that the heating temperature is appropriate and avoids damage to the scalp, which significantly improves the hair growth effect and the safety of use.

[0016] 2. This multifunctional lightweight hair growth device based on laser components involves assembling a first flexible circuit board against the inner wall of the helmet body. The first flexible circuit board is then bonded to the flexible heat-conducting layer via a heat insulation layer. A second flexible circuit board is then fixed to the flexible heat-conducting layer using a heat-conducting adhesive layer. The helmet body is made of ABS engineering plastic to reduce overall weight. Two internal elastic adjustment straps are attached with Velcro, allowing for adjustment to different head shapes. The flexible heat-conducting layer uses flexible silicone heat-conducting sheets to conform to the curvature of the scalp, while the heat insulation layer uses ceramic fiber insulation cotton to prevent heat transfer to the helmet body. The combination of the flexible heat-conducting layer and the flexible circuit board adapts to the curved structure of the helmet body, ensuring that components such as the laser beads and low-frequency ultrasonic transducer fit tightly to the scalp, enhancing the effect. The heat insulation layer prevents heat loss and helmet body heating, ensuring wearing comfort. The ABS engineering plastic helmet body balances lightweight and rigidity, and the elastic adjustment straps allow for personalized wearing to meet different user needs. Furthermore, the adhesive bonding of each layer ensures the stability of the component installation.

[0017] 3. This multifunctional lightweight hair growth device based on laser components allows for easy maintenance of components such as laser beads and low-frequency ultrasonic transducers by using a second flexible circuit board, which is easily separated through the adhesive layer and flexible heat-conducting layer. Wires are routed through through-holes in the heat insulation layer, preventing messy wiring and facilitating cable management. The second flexible circuit board is secured inside the helmet body with several snap-fit ​​pins for quick disassembly. The controller and speaker are embedded in the helmet body, with wiring electrically connected to the controller via the first flexible circuit board; maintenance only requires disconnecting the corresponding wires. Modular assembly of functional components and the snap-fit ​​pin structure and adhesive layer design eliminate the need for complex tools, reducing the difficulty for users to replace easily damaged parts. The through-hole design standardizes wire layout and facilitates cable maintenance. The controller integrates the main control, Bluetooth, and power modules, simplifying the circuit structure, reducing potential failure points, and lowering equipment maintenance costs and downtime.
