The invention provides a laser hair growth instrument.
In the embodiment of the present invention, as shown in fig. 1, the laser hair growth instrument 10 includes a housing 100, a circuit board 200, a laser light source 300, and a functional film 400.
The circuit board 200 is provided on the housing 100.
The laser light source 300 is disposed on the circuit board 200, and the light emitting surface 302 of the laser light source 300 is located on a side of the circuit board 200 away from the housing 100. The laser light source 300 is plural, and the plural laser light sources 300 are arranged at intervals. The laser light source 300 emits light spots that stimulate the scalp, promote hair regrowth, and prevent hair loss.
In the present embodiment, the laser light source 300 is connected to the power supply system through the circuit board 200. It is understood that in other embodiments, the laser light source 300 may be connected to the power supply system through a conductive wire, and in this case, the circuit board 200 may be omitted and the laser light source 300 may be disposed on the housing 100.
The functional film 400 covers the plurality of laser light sources 300. Thus, the functional film 400 can effectively protect the laser light source 300 and can also protect electronic components on the circuit board 200.
In this embodiment, the functional film 400 includes a base region 402 and a light source region 404 integrally formed with the base region 402. The number of the light source regions 404 is the same as that of the laser light sources 300, and the light source regions are arranged in a one-to-one correspondence. The light source region 404 includes a spot enlarging portion 410, and the spot enlarging portion 410 is used to enlarge the spot emitted from the laser light source 300.
The spot enlargement part 410 may enlarge the spots emitted from the laser light sources 300, so as to facilitate the irradiation of all the scalps, and further facilitate the improvement of the treatment effect, so that the laser hair growth instrument 10 has a better treatment effect, and the irradiation of the scalps of the same area may be realized by using a relatively small number of the laser light sources 300. The cost of the laser hair growth instrument 10 can be reduced by using a relatively small number of laser light sources 300.
The light source area 404 and the base area 402 are integrally formed (that is, the light spot amplifying part 410 and the base area 402 are integrally formed), and compared with the arrangement of assembling the light spot amplifying part 410 and the base area 402, the step of assembling the light spot amplifying part 410 and the base area 402 can be omitted, so that the assembling time is saved, the assembling cost of the laser hair growth instrument 10 can be reduced, the production efficiency of producing the laser hair growth instrument 10 can be improved, the more the number of the laser light sources 300 is, the more the assembling cost is reduced, and the more the production efficiency is improved. In this case, the functional film 400 has at least two functions of protecting the laser light source 300 and amplifying a spot emitted from the laser light source 300.
Specifically, in the present embodiment, the light source area 404 and the base area 402 are made of the same material, and are made of plastic, and the light source area 404 and the base area 402 are integrally formed by injection molding.
In some embodiments, as shown in fig. 1-6, the spot enlarging portion 410 is a lens. Specifically, as shown in fig. 1, the light spot enlarging portion 410 is located on both sides in the light outgoing direction, and is a concave surface that is recessed. As shown in fig. 2, the spot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to the circuit board 200 is a flat surface, and a side far from the circuit board 200 is a recessed concave surface. As shown in fig. 3, the spot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to the circuit board 200 is a concave surface that is recessed, and a side far from the circuit board 200 is a flat surface. As shown in fig. 4, the spot enlargement portion 410 is located on both sides in the light outgoing direction, and is convex. As shown in fig. 5, the spot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to the circuit board 200 is a plane, and a side far from the circuit board 200 is a convex surface. As shown in fig. 6, the spot enlargement portion 410 is located on two sides in the light outgoing direction, the side close to the circuit board 200 is a convex surface, and the side far from the circuit board 200 is a plane.
In the present embodiment, the spot enlargement portion 410 is spaced from the light emitting surface 302 of the laser light source 300 in the light emitting direction. In this manner, the spot amplifying section 410 is more convenient to amplify the spot emitted from the laser light source 300, and is also convenient to dissipate the heat generated by the operation of the laser light source 300.
In this embodiment, as shown in fig. 1, an avoiding hole is formed in a region of the base region 402 corresponding to the laser light source 300, and the laser light source 300 is located in the avoiding hole. The light source region 404 further includes a surrounding portion 420, the surrounding portion 420 is disposed around the laser light source 300, and one end of the surrounding portion 420 close to the circuit board 200 is connected to the periphery of the avoiding hole. The end of the surrounding portion 420 away from the circuit board 200 may be used to dispose the spot enlargement portion 410, so as to very conveniently realize the separation of the spot enlargement portion 410 and the light emitting surface 302 of the laser light source 300 in the light emitting direction.
In some embodiments, as shown in fig. 1, an end of the surrounding portion 420 away from the circuit board 200 is an open end, and a periphery of the spot enlargement portion 410 is connected to a periphery of the open end and closes the open end. In some embodiments, as shown in fig. 4, an end of the surrounding portion 420 away from the circuit board 200 is a closed end, and the spot enlargement portion 410 is located outside the surrounding portion 420 and on the closed end.
The surrounding portion 420 may surround the laser light source 300. In some embodiments, as shown in FIG. 1, the surround 420 has a hemispherical shape. In some embodiments, as shown in fig. 7, the surround 420 is square.
In the present embodiment, as shown in fig. 1, the laser generator 10 further includes a positioning column 500, and an end surface of the positioning column 500 away from the circuit board 200 is located outside a side of the spot enlargement portion 410 away from the circuit board 200. When the laser hair growth instrument 10 is used, one end of the positioning column 500, which is far away from the circuit board 200, is used to abut against the scalp, so that when the laser hair growth instrument 10 is used, the distance between the light-emitting surface 302 (the light spot enlargement portion 410) of the laser light source 300 and the scalp can be limited by the positioning column 500, and the distance between the light-emitting surface 302 (the light spot enlargement portion 410) of the laser light source 300 and the scalp is prevented from being too close or too far. The distance between the light-emitting surface 302 (the spot enlargement portion 410) of the laser light source 300 and the scalp is too close to be beneficial to forming a large spot, and the distance between the light-emitting surface 302 (the spot enlargement portion 410) of the laser light source 300 and the scalp is too far to cause the power loss of the spot to be too large to reach the required power density.
In the present embodiment, a distance between the light emitting surface 302 of the laser light source 300 and one end of the positioning column 500 far away from the circuit board 200 is less than or equal to 2cm (centimeter). Specifically, in the present embodiment, a distance between the light emitting surface 302 of the laser light source 300 and one end of the positioning column 500 away from the circuit board 200 is 0.5-2cm (cm). More specifically, in the present embodiment, a distance between the light emitting surface 302 of the laser light source 300 and one end of the positioning column 500 away from the circuit board 200 is 1-2cm (centimeters).
In the present embodiment, the positioning pillars 500 are multiple, and the positioning pillars 500 are arranged at intervals. More specifically, in the present embodiment, the positioning column 500 is elongated. The positioning posts 500 are arranged in a comb shape.
In some embodiments, positioning post 500 is independent from light source area 404. The positioning column 500 is disposed through the base region 402 and is fixedly connected to the circuit board 200. The number of the positioning pillars 500 may be greater than, equal to, or less than the number of the laser light sources 300.
In some embodiments, as shown in fig. 1, the positioning column 500 is disposed on the base region 402, and the positioning column 500 is independent from the light source region 404, that is, the orthographic projections of the positioning column 500 and the light source region 404 on the same plane are independent from each other and do not overlap. The number of the positioning pillars 500 may be greater than, equal to, or less than the number of the laser light sources 300.
In the present embodiment, the positioning posts 500 are integrally formed with the base region 402. For reference column 500 and base district 402 assembly setting, reference column 500 and base district 402 integrated into one piece can omit the step of assembling reference column 500 and base district 402, practice thrift the assemble duration, not only can reduce the assembly cost that appearance 10 was grown to laser, can also improve the production efficiency that appearance 10 was grown to production laser, and reference column 500's figure is more moreover, and assembly cost's reduction is more obvious, and production efficiency's improvement is more obvious. In this case, the functional film 400 has at least three functions of protecting the laser light source 300, amplifying the laser light source 300, and positioning the scalp distance.
It should be noted that positioning column 500 is integrally formed with base region 402, and spot enlarging portion 410 is integrally formed with base region 402, that is, spot enlarging portion 410, positioning column 500 and base region 402 are integrally formed. Specifically, in the present embodiment, the material of the spot amplification portion 410, the positioning column 500 and the substrate area 402 are the same, and are all plastic materials, and may be integrally formed by injection molding. More specifically, in the present embodiment, the material of the spot enlargement portion 410, the positioning column 500, and the substrate area 402 is Polyvinyl chloride (PVC), and the light transmittance of the spot enlargement portion 410, the positioning column 500, and the substrate area 402 is greater than 90%.
In some embodiments, as shown in fig. 5, the positioning pillars 500 are disposed on the base region 402, and the number of the positioning pillars 500 is the same as that of the laser light sources 300, and the positioning pillars 500 are disposed in a one-to-one correspondence. That is, the positioning column 500 is a part of the light source area 404, and the light source area 404 includes the spot enlarging portion 410 and the positioning column 500. The spot enlargement unit 410 is disposed on the positioning post 500. Note that, when spot enlarging portion 410 is formed integrally with base region 402, "spot enlarging portion 410 is provided on positioning column 500" means that "spot enlarging portion 410, positioning column 500, and base region 402 are formed integrally".
In the present embodiment, as shown in fig. 8 and 9, the positioning pillars 500 surround the laser light sources 300, and at least a portion of the laser light sources 300 is received in the corresponding positioning pillars 500, at this time, a portion for receiving the laser light sources 300 is considered as a surrounding portion 420, and the positioning pillars 500 are captured on the surrounding portion 420. In some embodiments, as shown in fig. 8, the positioning pillar 500 is a hollow pillar with two open ends, and the laser source 300 and the spot enlargement portion 410 are both located in the positioning pillar 500. In this case, the positioning pillar 500 may be considered to include the surrounding portion 420, and the positioning pillar 500 has a function of the surrounding portion 420. In some embodiments, as shown in fig. 9, the positioning pillar 500 is a solid pillar, and one end of the positioning pillar 500 near the circuit board 200 is recessed to form a surrounding portion 420. At least one of the end surface of the positioning column 500 away from the circuit board 200 and the end surface of the surrounding portion 420 away from the circuit board 200 is an inward concave arc surface. The spot enlargement portion 410 includes one or two arcs.
In other embodiments, the positioning pillar 500 may not surround the laser light source 300, but is spaced from the laser light source 300 in the extending direction of the positioning pillar 500, and at this time, the laser light source 300 is not located in the positioning pillar 500.
The positioning column 500 not only can limit the distance between the light emitting surface 302 (the light spot enlargement portion 410) of the laser light source 300 and the scalp, and prevent the light spot enlargement portion 410 (the laser light source 300) from being too close to or too far from the scalp, but also can move the hair, and reduce the area of the scalp shielded by the hair, so that more scalp is irradiated by the laser, and the laser hair generator 10 has a better effect.
Particularly, when the positioning column 500 is tapered in the extending direction away from the circuit board 200, that is, the positioning column 500 is a tapered structure with a larger end and a smaller end, and the smaller end is used for abutting against the scalp, compared to the structure with the same two ends, the positioning column 500 with the tapered structure is more convenient for pulling the hair, and reduces the area of the scalp shielded by the hair.
Moreover, when the positioning posts 500 are disposed on the base region 402 and the number of the positioning posts 500 is the same as that of the laser light sources 300 and the positioning posts 500 are disposed in a one-to-one correspondence manner, that is, in the embodiment shown in fig. 8 and 9, the positioning posts 500 are used for guiding light and guiding out laser light emitted by the laser light sources 300, so that the scalp colliding with the positioning posts 500 can be irradiated by the laser light, and the scalp colliding with the positioning posts 500 can be prevented from being irradiated by the laser light. In this way, the positioning column 500 not only can limit the distance between the spot enlargement portion 410 and the scalp, but also can ensure a large irradiation area of the scalp.
Especially, when the positioning column 500 is a tapered structure, it is more convenient to conduct laser, wherein, part of the laser can pass through the whole positioning column 500 and then contact with the scalp, and part of the laser can pass through part of the positioning column 500 and then exit from the side of the positioning column 500, and then does not need to pass through the remaining part of the positioning column 500 and directly reaches the scalp, thereby reducing the laser loss and being more convenient to conduct laser.
Specifically, in the present embodiment, the power of the laser light source 300 is 1-5mW (milliwatt). The distance between the spot enlargement portion 410 and the light exit surface 302 of the laser light source 300 is less than 0.8 cm. The spot amplifying section 410 may amplify the spot of the laser light source 300 by 2 to 6 times. The distance between the light-emitting surface 302 of the laser light source 300 and one end of the positioning column 500 far away from the circuit board 200 is less than or equal to 2cm (centimeter). The power density of the light spot irradiated on the scalp is 3-15mW/cm2。
When the laser hair growth instrument 10 is manufactured, the laser hair growth instruments 10 of the small size, the medium size and the large size can be manufactured according to the size of the head shape of the crowd, but even if the division is made, the sizes of the head shapes of two different people located at the same level (for example, the head shapes of two different people are both medium-sized, and the laser hair growth instrument 10 of the medium size is applied) are different, and the head shapes of the different people are different. In this way, after the user wears the laser hair growth device 10, there is the positioning column 500 that cannot collide with the scalp, that is, there is the positioning column 500 spaced from the scalp. This results in the actual distance between the spot enlargement portion 410 and the scalp being greater than the preset distance between the spot enlargement portion 410 and the scalp. When the actual distance is greater than the preset distance, the actual spot area irradiated to the scalp is greater than the preset spot area, and the actual spot power density is smaller than the preset spot power density.
To ensure that the actual spot area of the laser hair growth instrument 10 is substantially the same as the pre-set spot area. In this embodiment, as shown in fig. 10, the laser hair growth instrument 10 further includes a driving member 600, the driving member 600 is disposed on the circuit board 200, and the driving member 600 is used for driving the functional film 400, so that the spot enlargement portion 410 moves close to or away from the laser light source 300, thereby adjusting the distance between the spot enlargement portion 410 and the light emitting surface 312 of the laser light source 300, and further adjusting the spot area irradiated to the scalp, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area.
For example, when the laser hair growth instrument 10 is worn on the head, the distance between the spot enlargement portion 410 and the laser light source 300 is an initial distance, and if the positioning column 500 is in contact with the scalp, it is considered that the actual spot area irradiated to the scalp is substantially the same as the preset spot area; if the positioning column 500 is spaced from the scalp, it is determined that the actual spot area irradiated to the scalp is larger than the preset spot area, and at this time, the driving member 600 drives the functional film 400 to move the spot enlarging portion 410 away from the laser light source 300, so that the distance between the spot enlarging portion 410 and the laser light source 300 is increased, the actual spot area irradiated to the scalp is reduced, and the actual spot area irradiated to the scalp is substantially the same as the preset spot area.
When the laser hair growth instrument 10 is worn on the head and the distance between the spot enlargement portion 410 and the laser light source 300 is not the initial distance, the driving member 600 drives the functional film 400 to move the spot enlargement portion 410 away from or close to the laser light source 300, so that the distance between the spot enlargement portion 410 and the laser light source 300 is increased or decreased, and the actual spot area irradiated to the scalp is substantially the same as the preset spot area.
It should be noted that, in this embodiment, the actual spot area irradiated to the scalp is substantially the same as the preset spot area, which means that the actual spot area is 80% -120% of the preset spot area. It is understood that in other embodiments, the actual spot area irradiated to the scalp may be substantially the same as the preset spot area, which may also mean that the actual spot area is 90% -110% of the preset spot area.
To ensure that the actual spot power density is substantially the same as the preset spot power density, in this embodiment, the emission power of the laser light source 300 is adjustable. When the driving member 600 drives the functional film 400, the light spot enlarging portion 410 moves close to or away from the laser light source 300, so that the emission power of the laser light source 300 is increased after the actual light spot area irradiated to the scalp is approximately the same as the preset light spot area, the actual light spot power density is increased, and the actual light spot power density is approximately the same as the preset light spot power density.
That is, in the present embodiment, the distance between the spot enlargement part 410 and the laser light source 300 may be adjusted, and the emission power of the laser light source 300 may be adjusted, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area, and the actual spot power density is substantially the same as the preset spot power density.
It should be noted that, in this embodiment, the actual spot power density is substantially the same as the preset spot power density, which means that the actual spot power density is 80% -120% of the preset spot power density. It is understood that, in other embodiments, the actual spot power density is substantially the same as the preset spot power density, which may also mean that the actual spot power density is 90% -110% of the preset spot power density.
Specifically, in the present embodiment, the laser hair growth instrument 10 further includes a distance sensor (not shown). The distance sensor is disposed on the circuit board 200, and is used for obtaining an actual distance between the light emitting surface 302 of the laser light source 300 and the scalp. The driving member 600 is electrically connected to the distance sensor, and the driving member 600 can drive the functional film 400 according to the actual distance, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area.
In practical applications, when the laser hair growth instrument 10 is worn on the head, the actual distance between the light-emitting surface 302 of the laser light source 300 and the scalp is determined, and when the actual distance between the light-emitting surface 302 of the laser light source 300 and the scalp is obtained by the distance sensor (for example, the actual distance is 5mm, which is greater than the preset distance 4mm between the light-emitting surface 302 of the laser light source 300 and the scalp, and at this time, the positioning column 500 is spaced from the scalp by 1mm), the driving member 600 can drive the functional film 400 according to the actual distance, so that the distance between the spot enlarging portion 410 and the laser light source 300 is increased (for example, increased by 0.1mm), and at this time, the actual spot power density is substantially the same as the preset spot power.
Specifically, in this embodiment, the laser hair growth instrument 10 further includes a main control board, and the distance sensor and the driving member 600 are electrically connected to the main control board. The memory of the main control board stores a correspondence table between "the actual distance between the laser light source 300 and the scalp" and "the distance between the spot enlargement unit 410 and the laser light source 300" in advance, and the correspondence table is obtained by an experimental test. Thus, when the distance sensor obtains the actual distance between the laser light source 300 and the scalp, the increase in the distance between the spot enlargement unit 410 and the laser light source 300 can be obtained by looking up the table.
Specifically, in the present embodiment, the memory of the main control board also prestores a correspondence table between "the increase in the distance between the spot enlargement portion 410 and the laser light source 300" and "the emission power of the laser light source 300", which is obtained through experimental tests. Thus, when "the distance between the spot enlargement unit 410 and the laser light source 300 is increased" is obtained, the "emission power of the laser light source 300" can be obtained by looking up the table.
It should be noted that in the present embodiment, the driving member 600 is activated only when the absolute value of the difference between the actual distance and the preset distance is greater than 10% of the preset distance. That is, when the absolute value of the difference between the actual distance and the preset distance is less than or equal to 10% of the preset distance, the driving member 600 is not activated. For example, when the actual distance is 5mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 25% of the preset distance and is greater than 10%, and the driving member 600 is activated; when the actual distance is 4.4mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 10% of the preset distance and is not greater than 10%, and the driving member 600 is not started; when the actual distance is 3.5mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 12.5% of the preset distance and is greater than 10%, and the driving member 600 is started. It will be appreciated that in other embodiments, the drive member 600 is only activated when the absolute value of the difference between the actual distance and the preset distance is greater than 5% of the preset distance.
It should be noted that, in this embodiment, when the actual spot power density is 80% -120% of the preset spot power density, the emission power of the laser light source 300 is not adjusted. When the absolute value of the difference between the actual spot power density and the preset spot power density is greater than 20% of the preset spot power density, the emission power of the laser light source 300 is increased. It is understood that in other embodiments, the emission power of the laser light source 300 is increased when the absolute value of the difference between the actual spot power density and the preset spot power density is greater than 10% of the preset spot power density.
In the above embodiments, the difference between the "actual distance between the light emitting surface 302 of the laser light source 300 and the scalp" (for example, the actual distance is 5mm, which is greater than the preset distance 4mm between the light emitting surface 302 of the laser light source 300 and the scalp, and at this time, the distance between the positioning post 500 and the scalp is 1mm) "and the" distance between the spot enlargement portion 410 and the laser light source 300 is increased (for example, increased by 0.1mm) "is very large, and at this time, the positioning post 500 and the scalp are still spaced. That is, the adjustment in the above embodiment is fine adjustment, and is very easy to implement.
In the present embodiment, the functional film 400 and the housing 100 form a closed protection cavity, so as to limit the circuit board 200 within the protection cavity. Thus, the circuit board 200 can be well protected against falling, water and dust.
Specifically, in the present embodiment, the circuit board 200 is movably disposed in the protective cavity formed by the functional film 400 and the housing 100. Thus, it is more convenient to assemble the housing 100, the circuit board 200 and the functional film 400.
The laser hair growth instrument 10 further comprises an elastic connector, which connects the circuit board 200 and the base region 402 of the functional film 400. The elastic connection button can fix the positions of the circuit board 200 and the functional film 400, thereby ensuring that each light source region 404 and the laser light source 300 are in one-to-one correspondence, and ensuring the initial distance between the spot enlargement portion 410 and the laser light source 300.
In this embodiment, under the action of the driving member 600, the functional film 400 deforms to drive the spot enlargement portion 410 to be away from the laser light source 300, and after the action of the driving member 600 is cancelled, the functional film 400 returns to the original state. I.e., the functional film 400 has a certain elasticity. In this manner, it is very convenient to realize fine adjustment between the laser light source 300 and the spot amplifying section 410.
In the present embodiment, the driving member 600 is located between the circuit board 200 and the base region 402. Thus, the functional film 400 can shield and protect the driving member 600. More specifically, in the present embodiment, the driving element 600 is disposed corresponding to the positioning column 500, so that it is more convenient to make the positioning column 500 abut against the scalp. More specifically, in the present embodiment, the driving member 600 is a micro motor.
In other embodiments, the driving member 600 can also greatly adjust the distance between the spot enlargement portion 410 and the laser source 300, so that the positioning column 500 abuts against the scalp. So, be more convenient for reference column 500 to stir the hair, reduce the area of the scalp that is shielded by the hair to make more scalps by laser irradiation, and then make laser hair growth appearance 10 have better effect. In practical applications, after wearing the laser hair growth instrument 10, when a user feels the pressing of the positioning column 500, it indicates that the positioning column 500 is abutted against the scalp. When the user cannot feel the pressing of the positioning column 500, it indicates that the positioning column 500 does not abut against the scalp, and at this time, the driving member 600 may be turned on, so that the driving member 600 drives the functional film 400 to approach the scalp, and the positioning column 500 abuts against the scalp. In this case, the distance sensor may be omitted.
The embodiment also provides a calibration method of the laser hair growth instrument, which comprises the following steps:
step S10a, the laser hair generator is worn on the head.
Step S10b, obtain the actual distance between the light emitting surface of the laser light source and the scalp.
Step S10c, when the actual distance between the light-emitting surface of the laser light source and the scalp is greater than the preset distance between the light-emitting surface of the laser light source and the scalp, adjusting the distance between the spot enlargement portion and the light-emitting surface of the laser light source so that the actual spot area irradiated to the scalp is 80% -120% of the preset spot area.
Step S10d, increasing the emission power of the laser light source to make the actual spot power density 80% -120% of the preset spot power density.
In the present embodiment, the emission power of the laser light source 300 is adjustable. Therefore, the emitting power with proper size can be selected according to actual requirements, and the laser hair growth instrument 10 has a better treatment effect.
In this embodiment, the laser hair growth instrument 10 further includes a laser doppler blood flow sensor 700, and the laser doppler blood flow sensor 700 is disposed on the circuit board 200 and is used for detecting the blood flow velocity of the scalp tissue. Specifically, as shown in fig. 10, the laser doppler blood flow sensor 700 is located between the circuit board 200 and the base region 402.
The laser emitted by the laser hair growth device 10 can promote blood circulation, i.e. accelerate the flow rate of blood. The laser doppler blood flow sensor 700 can detect the flow velocity of blood, and its specific working principle is as follows: the laser doppler blood flow sensor 700 emits a laser beam that is scattered by the scalp tissue (the tissue under investigation) and then a portion of the laser is absorbed by the scalp tissue. The laser wavelength that hits the blood cells is changed (i.e., doppler shifted) while the laser wavelength that hits the stationary tissue is unchanged. The intensity and frequency distribution of these wavelength changes is directly related to the number of blood cells in the scalp tissue and the speed of movement. The laser doppler blood flow sensor 700 obtains information such as the number of blood cells and the moving speed through the receiving optical fiber, converts the information into an electric signal, and analyzes the electric signal, thereby obtaining the flow velocity of blood in the scalp tissue.
In actual use, the laser doppler blood flow sensor 700 may be used to obtain blood flow velocity information before use, and then the laser hair growth instrument 10 may be used to perform laser irradiation. After the irradiation for a preset time, the current blood flow rate information is obtained by using the laser doppler blood flow sensor 700. If the current blood flow rate does not reach the predetermined value, the laser is continuously irradiated or the emitting power of the laser light source 300 is increased to obtain a better treatment effect.
In the present embodiment, the laser hair growth instrument 10 is a portable laser hair growth instrument. Specifically, in the present embodiment, as shown in fig. 11 to 13, the housing 100 has a cap shape to enclose the head of the user. That is, in the present embodiment, the laser hair growth instrument 10 is a hair cap. In other embodiments, the laser hair generator 10 may be a head-wearing structure such as a hair band or a hair band.
In the present embodiment, the shell 100 includes a crown region 110, a forehead region 120, a left side region 130, a right side region 140, and a back cranium region 150.

The dotted line in fig. 10 is the boundary between the crown region 110 and the forehead region 120. Specifically, in the present embodiment, the number of the laser light sources 300 is 64, 81, 100, 202, or 272.
In traditional cap of growing hair, the parietal region, forehead district, left lateral region, right side district and the back of the head district of shell all are provided with laser source, and laser source's figure is many, leads to the cost of cap of growing hair higher. In practical application, the hair loss of the head area 110 and the forehead area 120 of the head of the user is relatively serious, the hair loss of the areas such as the left side area 130, the right side area 140 and the back head area 150 is relatively light, and the laser light sources 300 are arranged in the head area 110 and the forehead area 120, but the laser light sources 300 are not arranged in the areas such as the left side area 130, the right side area 140 and the back head area 150, so that the purpose of treating the hair loss can be achieved, the number of the laser light sources 300 can be reduced, and the cost of the laser hair growth instrument 10 can be reduced.
In the present embodiment, the circuit board 200 is disposed on the crown region 110 and the forehead region 120, and extends to the left region 130, the right region 140, and the back of the brain region 150. That is, in the present embodiment, the area of the circuit board 200 is larger than the arrangement area of the plurality of laser light sources 300, so that it is convenient to provide other functional elements, such as a temperature sensor, a humidity sensor, and the like, on the circuit board 200.
In this embodiment, the circuit boards 200 are two, and the two circuit boards 200 are distributed on the left and right sides of the center line of the corresponding head of the housing 100. In this manner, it is more convenient to arrange the circuit board 200 such that the circuit board 200 matches the shape of the housing 100.
In the present embodiment, the functional film 400 is a single piece, and the functional film 400 is disposed on the circuit board 200 and covers the crown region 110 and the forehead region 120. In this manner, the assembly of the functional film 400 is more facilitated. It is understood that the functional film 400 may be multiple pieces in other embodiments. For example, the functional film 400 may be two pieces, one piece being disposed corresponding to the parietal region 110 and the other piece being disposed corresponding to the forehead region 120; for another example, when the circuit board 200 is two, the functional films 400 may be four, wherein each two functional films 400 are disposed corresponding to one circuit board 200 (the two functional films 400 correspond to the left vertex region 112 and the left forehead region 122 on the lower side of fig. 12), and one functional film 400 is disposed corresponding to the vertex region 110 and the other functional film 400 is disposed corresponding to the forehead region 120 in the two functional films 400 corresponding to the same circuit board 200.

In this embodiment, the laser hair growth instrument 10 further includes a heat sink. The heat sink is disposed between the circuit board 200 and the housing 100. The fins are multiple pieces distributed over the crown area 110 and the forehead area 120. In this way, when the laser hair growth instrument 10 is in operation, the heat sink can transfer heat generated by the operation of the laser light source 300 to the housing 100 through the circuit board 200. Furthermore, the heat dissipation fins are disposed on the crown area 110 and the forehead area 120, but not on the left area 130, the right area 140, the back head area 150, and other areas, so as to reduce the cost and avoid the weight of the laser hair growth device 10 from being too heavy due to the addition of many heat dissipation fins.
In this embodiment, the heat sink is a metal sheet. Therefore, the laser hair growing instrument 10 has a good heat dissipation effect, and the laser hair growing instrument 10 has light weight.
In order to facilitate the placement of heat sinks in the areas of the circuit board 200 corresponding to the crown area 110 and the forehead area 120, no short-circuit issues need to be considered. In the present embodiment, the circuit board 200 is provided with an insulating and heat conducting layer between the heat sink and the circuit board 200. The insulating heat conduction layer can be heat conduction glue with good heat conduction performance.
In the present embodiment, an end of the heat sink away from the circuit board 200 is disposed through the housing 100 and exposed from an outer surface of the housing 100. Thus, the end of the heat sink away from the circuit board 200 can directly contact with the outside atmosphere, which is more beneficial to heat dissipation. Specifically, in the present embodiment, an end of the heat sink away from the circuit board 200 is inserted into the heat dissipation through hole of the housing 100 in an interference manner. Thus, the laser hair growth instrument 10 not only has a good heat dissipation function, but also has good dustproof and waterproof functions.
In this embodiment, the laser hair growth instrument 10 further includes a signal line 800, one end of the signal line 800 is connected to the circuit board 200, and the other end is used for connecting to a power supply system. Specifically, in the present embodiment, one end of the signal line 800 away from the circuit board 200 is a USB interface 810. Therefore, the laser hair growth instrument 10 is very convenient to be connected with a power supply system, and the power supply system can be a power supply system which is easy to carry by a charger and a notebook.
In this embodiment, the laser hair growth instrument 10 further includes a pad, and the pad is detachably disposed in the housing 100 and corresponds to the posterior cerebral-cephalic region, so that the laser hair growth instrument 10 can be suitable for at least two heads with different sizes. When wearing the laser generator 10, the use or non-use of the pad can be selected depending on the size of the head, thereby matching heads of different sizes.
Specifically, in the present embodiment, the pad is an elastic pad or an inflatable pad. Thus, the laser hair growth instrument 10 can be matched with more heads with different sizes.
In this embodiment, the laser hair growth instrument 10 further includes a cap, and the housing 100 is detachably connected to the cap. Wherein, the cap can hide elements such as the shell 100, the circuit board 200, the laser light source 300 and the functional film 400, and the external structure of the laser hair growth instrument 10 can be changed by replacing different caps, so as to meet the diversified requirements of the user on the laser hair growth instrument 10.
