The problem of hair loss is troubling not only many men, but also more and more women. According to research data, the phenomenon of alopecia gradually shows a trend of youthfulness, and is about to become a big problem which troubles the whole society in the near future.

Researches show that the red light with the wavelength of 635-670 nm irradiates a human body to have the functions of promoting blood circulation and cleaning blood, and can improve and recover the physiological function of the blood. When the red light irradiates the scalp of a person, the hair follicle can be promoted to stretch, and the hair-growing agent has a good effect on hair root regeneration.

The serious problem of fever is easy to cause burn of users, and during the use process, the activity of hair follicle cells can be irreversibly damaged by overhigh temperature, which is not beneficial to the growth of hair.

Therefore, there is a need in the art for a technique for promoting hair growth, which is used to promote the proliferation of hair follicle cells in the skin, thereby promoting the growth of hair and other various hairs.

As described above, the hair and all nutrients required by the hair follicle are provided by the blood in the bottom of the hair follicle and in the capillaries, and if the hair has insufficient nutrients, the problems of dryness, yellowing, branching, shedding and the like occur.

To promote the proliferation of hair follicle cells and thereby achieve the effect of promoting hair growth, embodiments of a method of promoting hair growth, embodiments of a device for promoting hair growth (hereinafter referred to as hair growth device), embodiments of a computer readable medium, and embodiments of a hair growth cap are provided.

It will be appreciated by those skilled in the art that, in the present embodiment, the above-described method for promoting hair growth and device for promoting hair growth can be applied to the scalp, thereby playing a role in promoting hair regrowth and promoting rapid growth of short hair into long hair. In other embodiments, the method and device for promoting hair growth can be applied to the skin of other animals such as sheep, so as to promote the hair growth of wool and other animals.

It will also be appreciated by those skilled in the art that the hair growth cap provided in the present embodiment may be a specific device for applying a device for promoting hair growth to hair growth applications. The hair growth cap may have all the features of a device for promoting hair growth. Accordingly, in some specific implementations, the device for promoting hair growth may also have all or part of the features of a hair growth cap.

Referring to fig. 1, fig. 1 illustrates a schematic flow diagram of a method for promoting hair growth provided according to an aspect of the present invention.

As shown in fig. 1, the method for promoting hair growth provided by the present embodiment may include the steps of:

101: the LED light-emitting unit emits high-intensity pulse red light with low duty ratio.

As described above, the scalp of a person is irradiated with red light to promote the expansion of hair follicles, thereby having a good effect on the regeneration of hair roots. The LED light-emitting unit is mainly used for emitting red light which can promote hair follicles to stretch. The red light may include red visible light having a wavelength range of 780nm or less, infrared light having a wavelength range of near to or above 780nm, or a combination of the above red visible light and the above infrared light.

Compared with a laser lamp adopted by the existing hair growing device, the LED light emitting unit adopted by the embodiment can more efficiently emit red light (light with large wavelength) with adjustable wavelength, so that the red light with the most appropriate wavelength provided for a user is provided according to the actual using effect of the user. Meanwhile, the LED light-emitting unit is a cold light source, and the LED light-emitting unit is adopted to emit red light, so that electric energy can be effectively saved, and the heating phenomenon of the hair growing device is weakened.

In addition, the LED light-emitting unit also has the characteristic of high response speed. The LED light-emitting unit can accurately generate a pulse red light waveform with better hair growth effect according to a driving signal sent by the driving circuit.

Because the existing hair growing devices mostly adopt red light in a direct current form, the scalp temperature of a user must be maintained not to be higher than 41 ℃ in consideration of the temperature bearing capacity of the skin of the user. Therefore, 8mW/cm cannot be generally used²The direct current red light with the above illumination intensity irradiates the scalp of the user,to prevent burning of the user's scalp and thereby causing irreversible damage to hair follicle cells of the scalp. However, a great deal of experimental data show that the promotion effect of the red light with low illumination intensity on the hair growth is not ideal, thereby seriously hindering the popularization and development of the photodynamic hair growth technology.

Referring further to fig. 2, fig. 2 is a graph illustrating the correspondence between the illumination intensity and the relative cell proliferation rate of skin cells according to an embodiment of the present invention.

It will be understood by those skilled in the art that the above-mentioned relative cell proliferation rate refers to the ratio of skin cells relative to a cell proliferation base, and does not refer to the absolute proliferation amount of skin cells.

As shown in fig. 2, different illumination intensities can cause significant differences in the proliferation rate of skin cells within the same illumination time. After a continuous irradiation of 30 minutes, the usual intensity of light is 3mW/cm²The direct current photodynamic hair growth device can only promote the relative proliferation of skin cells by 10 percent, and the effect of promoting the hair growth is very little.

By arranging a large number of heat dissipation structures, the illumination intensity of the high-power helmet-type hair growth device can be increased to 8mW/cm²So that a relative cell proliferation rate of more than 50% was obtained after 30 minutes of continuous irradiation. However, as mentioned above, the heavy and bulky shape of the head-mounted hair-growing device can reduce the wearing comfort of the user and can easily burn the scalp of the user by accident, thereby seriously limiting the popularization and application of the photodynamic hair-growing device.

Compared with the direct current red light adopted by the existing hair growing device, the pulse red light provided by the embodiment has the characteristics of high illumination intensity and low duty ratio. The pulse red light with high illumination intensity and low duty ratio can improve the instantaneous illumination intensity of the pulse red light to 32mW/cm while maintaining lower average power²The hair growing effect of the hair growing device is improved while the scalp of the user is prevented from being burnt.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a process of determining the illumination intensity and the duty ratio of pulsed red light according to an embodiment of the present invention.

As shown in fig. 3, in the method for promoting hair growth provided in this embodiment, the illumination intensity and the duty ratio of the pulsed red light may be determined by the following steps:

1011: the average power of the LED lighting unit is determined from the skin temperature.

As mentioned above, the upper limit of the human skin's tolerance to temperature is around 41 ℃. In order to prevent the scalp of the user from being burnt by excessive temperature and irreversible damage to hair follicle cells, in the method for promoting hair growth provided by the embodiment, the processing module of the hair growth device can comprehensively calculate the heat dissipation capacity of the hair growth device or monitor the skin temperature of the user in real time through a temperature sensor connected with the hair growth device, so as to determine the average power of the LED light-emitting unit.

In general, the average power density of the LED light emitting unit may be preferably 3-4mW/cm in consideration of the wearing comfort of the user and the volume of the hair growth device²Thus avoiding the use of bulky, bulky helmet-type designs. It will be appreciated that the average power of the LED lighting unit may be obtained by multiplying the average power density by the area of the hair generating means.

Due to 3-4mW/cm²Does not generate a large amount of heat, and the hair growing device can be simply set in the form of a cap so as to be worn by a user for a long time. Compared with a heavy and bulky helmet-type design, the hair-growing device in a hat type can be conveniently worn by a user at any time, and the user cannot feel heavy and inconvenient, so that the enthusiasm of the user for wearing the hair-growing device is improved.

It will be understood by those skilled in the art that the above temperature standard of 41 ℃ is only a specific case provided in the present embodiment, and is mainly used to more clearly show the main concept of the present invention, and provide a specific solution for the public to implement, not to limit the protection scope of the present invention. In other embodiments, a person skilled in the art may select a higher or lower temperature standard to determine the average power of the LED lighting unit according to the different temperature endurance of the user.

As shown in fig. 3, the method for determining the illumination intensity and the duty ratio of the pulsed red light provided by this embodiment may further include the steps of:

1012: the intensity of the pulsed red light is determined according to the proliferation rate of skin cells.

As described above, higher light intensity can better promote skin cell proliferation, thereby promoting hair growth. Especially in some specific illumination intensity ranges (e.g., 32mW/cm in FIG. 2)²Nearby), the proliferation rate of skin cells is increased sharply with the increase of illumination intensity, and thus a better hair growth effect is obtained. However, in consideration of the average power limit and the wearing time limit of the LED lighting unit, it is not desirable to increase the instantaneous illumination intensity of the LED lighting unit without limitation.

In the method for promoting hair growth provided in this embodiment, it may be preferable to first perform a test on skin cells of the user, and determine the most effective illumination intensity of the pulsed red light by the proliferation rate of the skin cells.

As shown in FIG. 2, at 32mW/cm²The relative proliferation rate of the skin cells of the user is obviously improved under the illumination intensity of the light. Therefore, it can be determined that the illumination intensity of the pulse red light most suitable for the user is 32mW/cm²。

It will be appreciated by those skilled in the art that the above method for determining the intensity of pulsed red light by detecting the proliferation rate of skin cells of a user provided in this embodiment is only one preferred approach for more accurately determining the intensity of pulsed red light. The most effective intensity of pulsed red light for skin cell proliferation of a user can be determined by performing the above-described detection only once before the user uses the hair growth device for the first time. In the subsequent use process of the user, the hair growing device can also directly adopt the determined pulse red light intensity to irradiate the skin hair follicle of the user so as to obtain the same hair growing effect, and the detection step is not required to be carried out every time.

It will also be appreciated by those skilled in the art that although the relationship between the proliferation rate of skin cells and the intensity of pulsed red light varies from person to person, a large amount of experimental data indicates that the optimal light intensity for each person does not vary greatly in the same application scenario (e.g., promoting hair growth).

Therefore, in other embodiments, the skin cell proliferation rate test can be performed on a large number of subjects in advance to obtain a universal illumination intensity of the pulsed red light (e.g., 30-40 mW/cm)²) So that the general light intensity of the pulse red light is directly input to the hair growing device through the setting module of the hair growing device in the implementation process of the method for promoting the hair growth.

1013: and determining the duty ratio of the pulse red light according to the average power of the LED light-emitting unit and the intensity of the pulse red light.

In the method for promoting hair growth provided by this embodiment, after determining the average power of the LED light-emitting unit and the light-emitting intensity of the pulsed red light, the processing module of the hair growth device may first calculate the illumination area of the LED light-emitting unit to determine the instantaneous power of the pulsed red light, and then determine the duty ratio of the pulsed red light according to the ratio of the average power to the instantaneous power. The duty ratio of the pulse red light can indicate the time proportion of the actually effective pulse red light in one pulse period.

For example: in the method for promoting hair growth provided in this embodiment, the duty ratio of the pulsed red light may be determined as an average power density (4 mW/cm)²) And instantaneous power density (32 mW/cm)²) I.e. 12.5%.

As will be appreciated by those skilled in the art, the above 4mW/cm²Average power density of 32mW/cm²The instant power density of (a) and the duty ratio of 12.5% are only a specific example provided in this embodiment, and are mainly used to clearly demonstrate the concept of the present invention and provide a solution that is convenient for the public to implement, but not to limit the protection scope of the present invention. In other embodiments, the present inventionOther average and instantaneous powers may be used by those skilled in the art based on the teachings of the present invention to determine other duty cycles.

Those skilled in the art will also appreciate that the above described scheme of calculating the pulse red duty cycle with the processing module of the hair generating device is only one specific case. In other embodiments, the duty ratio of the pulse red light may be calculated by other methods and then directly input to the hair growing device through the setting module for use.

In the method for promoting hair growth provided by the present embodiment, the LED light emitting unit of the hair growth device can emit high-intensity pulsed red light with a low duty ratio according to the illumination intensity and duty ratio of the pulsed red light obtained in any one of the above manners.

The required pulse red light dose also varies from person to person due to the different hair densities of different users. Thus, the present embodiment also provides a solution for determining the pulsed red light dose and the exposure time.

Referring further to fig. 4, fig. 4 is a schematic flow chart illustrating a method for determining the dose and exposure time of pulsed red light according to an embodiment of the present invention.

As shown in fig. 4, the method for determining the dose and the irradiation time of the pulsed red light provided by this embodiment may include the steps of:

1014: determining the dose of the pulsed red light according to the hair density of the hair follicle; and

1015: and determining the irradiation time of the pulse red light according to the dose of the pulse red light and the average power of the LED light-emitting unit.

The dose of the pulsed red light may be used to indicate the amount of light energy (in joules, J) that the user's skin follicles are illuminated with the pulsed red light over a period of time.

The experimental data show that the pulse red light has the effects of promoting the hair follicles with different hair densities to stretch and contract so as to regenerate hair roots and promote the hair growth. Therefore, a better hair growth effect can be obtained by increasing the dose of the pulsed red light.

Specifically, in the method for determining the dose and the irradiation time of the pulsed red light provided by this embodiment, the processing module of the hair growth device may count the average hair density of all hair follicles in the skin area designated by the user, and then determine the dose of the pulsed red light required by the user according to the average hair density and the experimental statistical data in advance. The above-mentioned preliminary experimental statistics may comprise the average pulse red light dose required for a user of different hair density to reach a standard hair density.

After determining the dose of pulsed red light required by the user to reach the standard hair density, the irradiation time of the pulsed red light can be determined by calculating the ratio of the dose of the pulsed red light to the average power of the LED lighting unit.

It will be appreciated by those skilled in the art that the above scheme for determining the dose and irradiation time of the pulsed red light is only a preferred scheme provided by the present embodiment, and is mainly used to prompt the customer of the required dose. In other embodiments, the user can shorten the irradiation time to reduce the dose of the pulse red light according to the good actual use effect of the user; or further increase the irradiation time to increase the dose of the pulsed red light according to the undesirable effect of practical use by oneself.

As shown in fig. 1, in the method for promoting hair growth provided in this embodiment, the method may further include:

102: the skin follicles are illuminated with pulsed red light to promote cell proliferation of the follicles.

As described above, irradiating the skin of the user with the pulsed red light can promote the skin hair follicle to stretch, which has a good effect on the regeneration of the hair root. In order to further improve the irradiation efficiency of the LED light-emitting unit, two preferable irradiation modes are provided in this embodiment.

In a preferred irradiation scheme, the high-intensity pulsed red light emitted by the LED light-emitting unit can be diffused by an optical diffuser arranged on the hair growth device, so that the diffused high-intensity pulsed red light uniformly irradiates the skin hair follicle to promote cell proliferation of more hair follicles.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a device 50 for promoting hair growth according to an embodiment of the present invention.

As shown in fig. 5, the optical diffuser 52 may be disposed between the LED lighting unit 51 and the skin 53. The optical diffuser 52 may be provided with a plurality of protruding structures 520, and the protruding structures 520 may have a pyramidal shape. The plurality of protrusion structures 520 may be unevenly disposed on the surface of the optical diffuser 52 to provide a more uniform diffusion effect.

Referring further to fig. 6, fig. 6 is a schematic diagram illustrating an optical path of a diffused light of an optical diffuser according to an embodiment of the present invention.

As shown in fig. 6, the light emitted from the LED light-emitting unit 51 can enter the optical diffuser 52 from below, and enter the optical diffuser 52 after being refracted for the first time at the entrance surface 521.

Light rays entering the optical diffuser 52 are refracted and reflected multiple times at the sidewalls of the protrusion structures 520 and exit the optical diffuser 52 in different directions.

Since the optical diffuser 52 generally has a higher refractive index than air, some of the light rays having an incident angle greater than the total reflection angle are totally reflected on the first refraction surface 522 and all propagate toward the second refraction surface 523. And the other part of the light rays with the incidence angle smaller than the total reflection angle can generate partial refraction and partial reflection. The partially refracted light rays exit the diffuser 52 from the first refractive surface 522 in the refractive angle direction. The partially reflected light propagates toward the second refraction surface 523 along the reflection angle direction.

By analogy, the pyramid-shaped protrusion 520 can diffuse the light incident toward the first refractive surface 521 in different directions according to the incident angle of the light. Similarly, the pyramid-shaped protrusion structure 520 may also diffuse the light propagating towards the other two refraction surfaces to different directions according to the incident angle of the light, so as to expand the irradiation area of each LED light-emitting unit 51 and avoid the patient from being burned due to too high irradiation intensity.

Correspondingly, the diffusion effect of the optical diffusion member 52 can be further improved by arranging the protrusion structures 520 with different sizes, different arrangement intervals and different slope included angles, so that a more uniform diffusion effect is macroscopically achieved.

In another preferred illumination scheme, the pulsed red light dissipated by the LED light emitting unit 51 and reflected by the skin 53 may be reflected to the skin follicle using an optically reflective layer 54 disposed on the hair growth device 50 to promote cell proliferation of the follicle.

As shown in fig. 5, the optical reflection layer 54 may be disposed on the outermost layer of the hair growing device 50, i.e., on the outer side of the LED light emitting unit 51. The optically reflective layer 54 can reflect pulsed red light scattered from the sides and back of the LED lighting unit 51 at a certain reflection angle to the skin follicles, thereby causing the skin follicles to stretch to promote hair growth.

It will be appreciated by those skilled in the art that animal skin, particularly the thin hair scalp, is generally highly greasy and therefore has a light reflectance of close to 30%. In the prior art, this portion of the reflected pulsed red light is typically embodied in the form of heat, burning the user's skin.

The optical reflective layer 54 provided in this embodiment can also reflect the red light of the pulse reflected after irradiating the skin back to the skin hair follicle, thereby again promoting hair follicle expansion. The experimental result shows that the multiple reflection of the pulse red light by the optical reflection layer 54 not only can effectively reuse the 30% of energy of the reflected pulse red light to improve the hair growth effect of the hair growth device 50, but also can further weaken the heating phenomenon of the hair growth device 50, so as to further improve the average power of the LED light emitting unit 51.

While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not limited by the order of acts, as some acts may, in accordance with one or more embodiments, occur in different orders and/or concurrently with other acts from that shown and described herein or not shown and described herein, as would be understood by one skilled in the art.

According to another aspect of the present invention, there is also provided herein an embodiment of a device for promoting hair growth.

As shown in fig. 7, the above-mentioned hair-growth promoting device 50 provided in the present embodiment may include an LED light emitting unit 51 and a light guide 52. The LED lighting unit 51 may be used to emit a low duty cycle, high intensity pulsed red light.

In a preferred embodiment, the device 50 for promoting hair growth provided by the present embodiment may further include a storage module 55 and a processing module 56. The processing module 56 is coupled to the storage module 55 and connected to each of the LED lighting units 51. Processing module 56 may be configured to implement any of the above-described methods for promoting hair growth, thereby promoting proliferation of hair follicle cells of the skin, and thus promoting hair growth and other various hair growth effects.

Accordingly, the above-mentioned hair-growth promoting device 50 provided by the present embodiment may further preferably include: the components necessary for implementing any of the above-described methods of promoting hair growth in conjunction with the processing module 56, such as: the embodiments described above refer to the optical diffuser 52 and the optical reflective layer 54.

According to another aspect of the present invention, there is also provided herein an embodiment of a computer readable medium.

The present embodiment provides the computer readable medium with computer instructions stored thereon, which when executed by the processing module 56, can implement any one of the above methods for promoting hair growth, so as to promote the proliferation of hair follicle cells of the skin, thereby achieving the effect of promoting hair growth and other various hair growths.

According to another aspect of the present invention, there is also provided herein an embodiment of a hair growing cap.

Referring to fig. 8, fig. 8 is a schematic cross-sectional view of a hair growing cap 80 according to another aspect of the present invention.

As shown in fig. 8, the above-mentioned hair growing cap 80 provided by the present embodiment may include: a cap body 81, an LED light emitting unit 82, and a light transmitting layer 83.

The LED light emitting unit 82 may be disposed inside the cap body 81 for emitting high intensity pulsed red light with a low duty cycle. The light emitting face of the LED light emitting unit 82 may be directed towards the scalp of the user to be grown.

The light-transmitting layer 83 may be disposed between the scalp of the user and the light-emitting surface of the LED light-emitting unit 82 for isolating the scalp of the user from the light-emitting surface of the LED light-emitting unit 82 and guiding the pulsed red light to irradiate hair follicles of the scalp of the user to promote cell proliferation of the hair follicles.

It will be appreciated by those skilled in the art that the hair growth cap 80 provided in the present embodiment may be a specific device for applying the above-described device 50 for promoting hair growth to hair growth. The hair growth cap 80 may have all of the features of the hair growth promoting device 50 described above. Accordingly, in some specific implementations, the hair-growth promoting device 50 described above may also have all or some of the features of the hair growth cap 80.

Since the LED light emitting unit 82 is spaced apart from the scalp of the user by the light transmitting layer 83, the pulsed red light emitted from the LED light emitting unit 82 can be sufficiently diffused within the thickness range of the light transmitting layer 83 to irradiate a larger area of the scalp of the user, thereby enlarging the hair growth area of each LED light emitting unit 82.

In a preferred embodiment, as shown in fig. 5 and 7, in order to better diffuse the above-mentioned pulse red light to obtain a better hair growth effect, an optical diffusion unit may be disposed in the light transmission layer 83 between each LED light emitting unit 82 and the scalp of the user for enlarging the irradiation area of the LED light emitting unit 82. The optical diffusion units may be provided with a plurality of pyramidal protrusion structures. The plurality of protrusion structures may be unevenly disposed on the surface of the optical diffusion unit to achieve a more uniform diffusion effect.

Accordingly, in one embodiment, the surface of the light transmissive layer 83 adjacent the scalp of the user may also be provided with a plurality of raised structures that are non-uniformly disposed to provide the same uniform spreading effect.

In a preferred embodiment, the light transmissive layer 83 may be made of a flexible material. The light emitting surface of the LED light unit 82 may be attached to the surface of the light transmissive layer 83 near the scalp of the user, such that the LED light unit 82 is disposed opposite to the surface of the light transmissive layer 83 near the scalp of the user. The light emitting surface of the LED light emitting unit 82 may be deflected in accordance with the deformation of the light transmissive layer 83.

It will be appreciated by those skilled in the art that in this embodiment, the light transmissive layer 83 of flexible material may provide greater comfort to the user when the user wears the hair growing cap 80 provided in this embodiment. Meanwhile, the light-transmitting layer 83 made of a flexible material can better fit the scalp of the user to reduce the dissipation of the pulse red light, thereby improving the energy efficiency of the hair growing cap 80 and reducing the heat generation phenomenon.

At this time, since the light emitting surface of the LED light emitting unit 82 is oriented to be deflected along with the deformation of the light transmissive layer 83, the light emitting surface of the LED light emitting unit 82 can always face the scalp hair follicle of the user, thereby providing uniform pulse red light for the scalp hair follicle of the user with the highest light emitting efficiency.

As shown in fig. 8, the hair growing cap 80 provided in this embodiment may further include a driving module 85, and the driving module 85 may be disposed at a closed position at the top of the cap body 81 for hiding.

The driving module 85 may include an input terminal and an output terminal. The inputs include, but are not limited to, a power input, a ground input, and a control input. The power input and the ground input of the driving module 85 can be respectively connected to the positive electrode and the negative electrode of a portable power source (e.g., a charger) for supplying power to the LED lighting unit 82.

It will be appreciated by those skilled in the art that the present embodiment provides the above-described hair growth cap 80 using a low power consumption LED light unit 82 and producing high intensity pulsed red light in the form of pulses with low average power. Thus, a portable power source, such as a power bank, can power the hair cap 80 for a long period of time. The portable power supply taking the charger as an example is used for supplying power to the hair growing cap 80, the load of a user can be further lightened, so that the comfort level is improved, and meanwhile, the user can wear the hair growing cap 80 in daily life for a long time without influencing daily activities of the user.

The control input of the driver module 85 may be connected to the processing module of the hair-growing cap 80 to obtain the pulse parameters needed to produce the pulsed red light. The pulse parameters include, but are not limited to, the instantaneous luminous intensity and duty cycle of the pulsed red light. The driving module 85 may generate a driving signal in response to the pulse parameter provided by the processing module, so as to drive the LED lighting unit 82 to emit corresponding pulse red light.

The output end of the driving module 85 may be connected to a power supply pin of the LED lighting unit 82 through a flexible circuit board, so as to drive the LED lighting unit 82 to emit pulse red light required by a user. The solution using the flexible circuit board is particularly suitable for the light-transmitting layer 83 made of the above-mentioned flexible material, so as to further enhance the wearing comfort of the user and facilitate the folding storage of the hair-growing cap 80.

In a preferred embodiment, in order to further provide more uniform pulsed red light for hair follicles of the scalp of a user to obtain a better hair growth effect, the hair growth cap 80 provided in the present embodiment may further include claw-shaped supports 86 made of an elastic material. The claw support 86 may be provided on the inside of the cap 81 and cover all or part of the scalp area. The claw-shaped support 86 may be used to fixedly connect all of the LED lighting units 82.

Referring to fig. 9, fig. 9 is a schematic structural diagram of a claw-shaped supporting member 86 provided inside a cap 81 according to an embodiment of the present invention.

As shown in fig. 9, the pawl support 86 may include a plurality of finger structures 861. The middle points of the plurality of finger structures 861 may be fixedly connected to the driving module 85, and the two ends thereof are respectively connected to the edge of the cap 81. A plurality of LED light units 82 may be fixedly disposed on each finger structure 861. The spacing between the plurality of LED light units 82 on each finger structure 861 may be determined by a claw support 86 made of a resilient material to promote uniformity of the pulsed red light provided to the hair follicles of the scalp.

It will be appreciated by those skilled in the art that the claw support 86 made of a resilient material can be snapped onto the user's head like an eagle claw to cover all or part of the scalp area and provide a certain amount of pressure to the light transmitting layer 83 made of a flexible material to allow it to be pressed against and deformed by the user's scalp.

Accordingly, the light emitting surface of the LED light emitting unit 82 is oriented to be deflected according to the deformation of the light transmissive layer 83, so that the scalp hair follicle of the user is always provided with uniform pulse red light with the highest light emitting efficiency with the light emitting surface thereof facing the scalp hair follicle of the user.

As shown in fig. 9, in a preferred embodiment, one or more finger 862 structures are also provided on the finger structure 861. The front end of the finger 862 may be rotatably connected to the finger 861 and the rear end may be connected to the rim of the cap 81.

One or more LED light units 82 may be fixedly disposed on each finger 862 to further cover the area of the scalp not covered by the finger 861, thereby providing a more uniform pulsed red light for the hair follicles of the scalp.

In a more preferred embodiment, the edge of the cap 81 may be further provided with a length-adjustable connector. The user can adjust the length of the connecting member according to the actual head circumference of the user, thereby adjusting the head circumference of the hair growing cap 80 to a proper size.

Accordingly, the above-described connectors may also connect the ends of all of the finger structures 861 and the finger 862 of the pawl support 86 in sequence. The user can tighten or loosen the finger structures 861 made of the elastic material by adjusting the length of the connecting member, thereby reducing or enlarging the distance between the two rows of the LED light emitting units 82 on the two adjacent finger structures 861.

Meanwhile, the user can drive the tail end of the interdigital structure 862 to rotate around the head end thereof by adjusting the length of the connecting piece, so as to approach or separate from the finger structure 861 adjacent to the interdigital structure 862, and further reduce or enlarge the distance between the LED light-emitting unit 82 on the interdigital structure 862 and the LED light-emitting unit 82 damaged by the adjacent finger structure 861.

In one embodiment, the flexible circuit board can be disposed in the finger structures 861 and the finger structures 862 to provide a certain supporting force for the flexible circuit board, so as to prevent the problem that frequent over-bending easily causes the flexible circuit board to break.

In a preferred embodiment, the hair growing cap 80 provided by the present embodiment may further include a plurality of sets of light reflectors for reflecting the pulsed red light dissipated by the LED light emitting unit 82 and the pulsed red light reflected by the scalp of the user to the hair follicles of the scalp to promote cell proliferation of the hair follicles.

Referring to fig. 8, fig. 10A and fig. 10B together, fig. 10A is a schematic perspective view illustrating a light reflector according to an embodiment of the present invention. Fig. 10B is a schematic cross-sectional view of a light reflector according to an embodiment of the present invention.

As shown in fig. 10A and 10B, the light reflector includes, but is not limited to, an outermost reflective layer 84 disposed inside the cap 81, and a plurality of reflective units 87 disposed around the plurality of LED light emitting units 82.

As described above, the reflective layer 84 provided on the outermost layer inside the cap body 81 can be provided outside the LED light emitting unit 82, and thus, the pulsed red light emitted from the side and rear of the LED light emitting unit 82 can be reflected at a certain reflection angle to the skin follicle, thereby promoting the skin follicle expansion and contraction to promote hair growth.

In addition, the scalp with thin hair generally has high grease, and therefore has light reflectivity close to 30%.

In the prior art, this portion of the reflected pulsed red light is typically embodied in the form of heat, burning the user's skin. The reflective layer 84 provided in this embodiment can reflect the red pulse light reflected after irradiating the scalp back to the hair follicle of the scalp of the user, thereby again promoting hair follicle stretching. The experimental result shows that the reflection layer 84 reflects the pulse red light for multiple times, so that the 30% of energy of the reflected pulse red light can be effectively reused to improve the hair growth effect of the hair growth cap 80, and the heating phenomenon of the hair growth cap 80 can be further weakened, so as to further improve the average power of the LED light emitting unit 82.

In one embodiment, as shown in fig. 10A, the above-described reflection unit 87 may be provided in the package lens 88 of the LED light-emitting unit 82 so as to make a one-to-one correspondence with the LED light-emitting unit 82. The reflecting unit 87 may be disposed around the LED light emitting unit 82 so as to surround the entire side surface of the LED light emitting unit 82 with its side reflecting surface 871. The side reflecting surface 871 of the reflecting unit 87 is mainly used to extract the side light emitted from the LED light emitting unit 82 to improve the light emitting efficiency thereof, thereby improving the hair growth effect of the hair growth cap 80.

As shown in fig. 10B, the reflection unit 87 may further include a front reflection surface 872. The front reflection surface 872 of the reflection unit 87 is mainly used for reflecting the pulse red light reflected by the scalp of the user again, so that the reflected pulse red light is reflected to the hair follicle of the scalp of the user again to promote the hair follicle to stretch, and further, the hair growth effect of the hair growth cap 80 is improved.

It can be understood by those skilled in the art that the reflective layer 84 and the reflective unit 87 are only a preferred solution provided by the present embodiment, and are mainly used for improving the light emitting efficiency of the hair growing cap 80, so as to improve the hair growing effect of the hair growing cap 80. In other embodiments, a person skilled in the art may also use only the above-mentioned reflective layer 84, or only the side reflective surface 871 or the front reflective surface 872 of the above-mentioned reflective unit 87 to obtain the corresponding reflective effect; or not using the light reflecting member provided in the preferred embodiment to achieve the basic hair growth promoting purpose.
