An embodiment of the present invention provides a head optical applying apparatus 100, as shown in fig. 1 to 3, the head optical applying apparatus 100 includes a fixed mounting body 110, a first optical member 130, and a body member 140. The fixed mounting body 110 is provided with a first rotating shaft 120. The first optical member 130 transmits or receives light to or from the scalp, and an insertion structure, such as a light guide, for inserting hairs therebetween is provided at a side of the first optical member 130 close to the scalp. The main body member 140 is provided with a first transmission portion 141 and a mounting hole 142 for mounting the first optical member 130, and the main body member 140 is fitted to the first rotating shaft 120 via the first transmission portion 141, so that the main body member 140 rotates with the first rotating shaft 120 and can move along the axial direction of the first rotating shaft 120 under an axial force.

The main body 140 is spaced apart from the fixed installation body 110 by a certain distance under the action of its own gravity, and under the condition of not being interfered by external force, the main body 140 can only rotate to make the insertion structure of the first optical member 130 poke hair, but when the rotation of the main body 140 is interfered by external force, for example, when the pressure between the main body 140 and the scalp is increased due to the rotation, the insertion structure will cause discomfort to the user if the main body 140 continues to rotate. Therefore, under the condition that the main body member 140 is interfered by external force, the main body member 140 is moved in the direction close to the fixed mounting body 110 by the axial acting force so as to be away from the head of the user, thereby achieving the effect of force leakage and avoiding discomfort to the user, and after the external force interference is cancelled, the main body member 140 can move towards the head of the user under the self gravity of the main body member 140, so that the state that the inserting structure of the first optical member 130 is attached to the scalp as much as possible can be kept in the whole process, and the hair can be rotated and stirred. The axial direction is understood to be the axial direction of the first rotating shaft 120, and the axial acting force is understood to be the resultant force applied to the main body member 140 in the axial direction, and can be generally considered to be the combined action of the component force generated in the axial direction by the acting force of the scalp which makes the main body member 140 unable to rotate and the self-weight of the main body member 140.

Specifically, the first rotating shaft 120 can be driven by a motor to rotate, and can also be manually operated by a user to rotate so as to rotationally stir the hair. In some embodiments, the first rotating shaft 120 may be driven by a motor to rotate or the first rotating shaft 120 is directly an output shaft of the motor, and the motor drives the main body member 140 to rotate forward and backward within a small range through the first rotating shaft 120, so as to implement the operation of rotating and dialing. The motor may be provided on the stationary mounting body 110. The motor may be, for example, a micro stepper motor. The motor can be controlled to rotate forwards and backwards within a small range by controlling the pulse frequency through software programming, so that the main body member 140 is driven to rotate forwards and backwards within a small range.

Specifically, the fixed mounting body 110 may be understood as a stationary member that can be fixed to the head of a user by a strap or the like, or as shown in fig. 3, to a support pole.

The first optical member 130 is used to transmit light to or receive light from the scalp, and specifically, the first optical member 130 may include an infrared LED lamp mounted to the body member 140, or an optical fiber, an optical waveguide member, or the like, which is introduced into the body member 140 from a light source independent from the body member 140 to irradiate the head of the user, and the first optical member 130 may include an optical fiber capable of receiving light emitted from the scalp when receiving light from the scalp, and an insertion structure for inserting a hair bundle is further provided on a side of the first optical member 130 close to the scalp. The insertion structure is, for example, a light guide member 240 as shown in fig. 4, and the light guide member 240 may be specifically configured to facilitate insertion of a light guide post between the hairs.

The body member 140 may also be provided with a device for feeding back the phototherapy effect, such as a temperature sensor for detecting the scalp temperature, a brain wave (EEG) collecting device, and the like.

According to the utility model, through the matching between the first rotating shaft 120 and the first transmission part 141 of the head optical applying device 100, the main body member 140 of the head optical applying device 100 can rotate along with the first rotating shaft 120 and can move along the axial direction of the first rotating shaft 120, so that the hair can be rotationally stirred, the light emitted by the optical member can be directly irradiated onto the scalp of a user, the light transmission rate is improved, the technical problem that the light transmission rate is reduced because the hair shields the light emitted by the optical member in the prior art is solved, the ideal treatment effect is achieved, and the brain function can be better improved.

In some embodiments, the portion of the first rotating shaft 120 connected to the first transmission part 141 is formed with an external spline structure; the first transmission part 141 is configured as an internal spline structure. The structural design of the inner spline structure and the outer spline structure has the advantages of stable transmission and good guidance quality. The spline structure is used to connect and fix the mounting body 110 and the main body member 140, so that the first optical member 130 can be prevented from being detached from the scalp due to excessive upward movement when the force is released, and the first optical member 130 can be attached to the scalp as much as possible.

In some embodiments, the insertion structure of the first optical member 130 is a light guide bar guiding light emitted from the light source to the scalp, and the light guide bar is formed by a material with certain elasticity, and the elastic design of the light guide bar is combined with the spline design and the gravity of the main body member, so that the first optical member 130 can keep a state of being attached to the scalp during the rotating and hair-poking process.

Specifically, the fixed mounting body 110 and the main body member 140 have a gap, so that the main body member 140 can move up and down relative to the fixed mounting body 110, and the width of the gap is smaller than the length of the external spline structure on the first rotating shaft 120, thereby ensuring that the external spline and the internal spline maintain a stable action relationship. The space provides and limits the space for the body member 140 to move up and down, and can ensure that the external spline is not separated from the internal spline.

Specifically, the external spline structure may be integrally formed on the outer wall of the first rotating shaft 120, and the internal spline structure may be integrally formed on the main body member 140.

In other embodiments, the first rotating shaft 120 is formed with a plurality of first protruding portions along a radial direction thereof, sliding grooves are formed between adjacent first protruding portions along an axial direction of the first rotating shaft 120, and the first transmission portion 141 has a second protruding portion configured to be slidably received in the sliding grooves and abut against the first protruding portions. Specifically, a gap may be formed between the second protruding portion and two adjacent first protruding portions, so as to facilitate the second protruding portion to move up and down in the sliding slot along the axial direction of the first rotating shaft 120. Further, the main body member 140 and the fixed mounting body 110 are further provided with an elastic member, which may be a spring or a leaf spring or others, for example. The elastic member with larger elasticity can be selected to realize that the main body member 140 can not only move along the sliding groove to release force, but also keep the main body member 140 close to the scalp so that the first optical member 130 keeps a state of being attached to the scalp during the rotating and hair-plucking process.

In some embodiments, as shown in fig. 1-3, the body member 140 is configured as a hat-type structure that fits the outer profile of the head; the body member 140 includes a top body 143 and an annular body 144 formed to extend outward along an edge of the top body 143, and a plurality of mounting holes 142 are formed in the top body 143 and the annular body 144, respectively.

Optionally, the plurality of mounting holes 142 are distributed in groups, and each group of mounting holes 142 corresponds to a brain target region. For example, if the head optical application device is used to treat alzheimer's disease, the mounting holes 142 are distributed in an area corresponding to a brain area associated with the treatment of alzheimer's disease. For example, if there are two brain regions related to treating alzheimer's disease, the two brain regions can be used as target brain regions, and a set of mounting holes 142 can be respectively arranged. Specifically, the main body member 140 may have a plurality of dimensions, so as to adapt to the size of the head circumference of different users, and the main body member 140 can fit the head of the user when different users use the head optical application device 100.

Specifically, the first optical member 130 may be installed in the installation hole 142, and the arrangement of the installation hole 142 may correspond to at least one region of the brain functional regions of the brain of the user, such as the occipital lobe, the frontal lobe, the parietal lobe, and the temporal lobe. In addition, when the head optical application device 100 is applied to a near-infrared brain imaging device, the mounting hole 142 can be used for mounting a transmitting probe or a receiving probe.

In some embodiments, as shown in fig. 3, the optical head applying apparatus 100 further includes a supporting rod 150 and a base 160, wherein one end of the supporting rod 150 is connected to the base 160, and the other end is bent and then connected to the fixed mounting body 110.

Specifically, the support bar 150 may be rotatably coupled to the base 160 to facilitate rotational positioning over the head of a user. Alternatively, the support bar 150 includes a bent portion and a straight portion, the bent portion being rotatably coupled with respect to the straight portion to facilitate rotational positioning over the head of the user.

In addition, the supporting rod 150 may also be a telescopic rod to flexibly adjust the positioning height of the fixed installation body 110 and facilitate the storage for the user. For example, the support bar 150 includes a bent portion and a straight bar portion, and the straight bar portion is a telescopic bar and can be adjusted in length according to the user's needs.

As described above, the head optical applying device provided by the present invention can rotate the optical member on the main body member by rotating the main body member, thereby implementing dialing, and further improving the light transmission rate, and can be used in the fields of light therapy, brain imaging, and the like.

Similarly, the above inventive concept can also be applied locally, i.e. using a similar structure to drive one optical member or a plurality of optical members located in a local small area. Based on this, the utility model proposes the following technical scheme.

As shown in fig. 4, the optical module 200 is disposed on the fixed housing 310, and the optical module 200 includes a power assembly 210, a rotating assembly 220, and a second optical member 230. The power assembly 210 includes a driving member 211 provided on the stationary housing 310 and a second rotating shaft 212 connected to an output shaft of the driving member 211. The rotating assembly 220 is rotatably mounted on the fixed housing 310, the rotating assembly 220 is provided with a second transmission portion 221, and the rotating assembly 220 is matched with the second rotating shaft 212 through the second transmission portion 221, so that the rotating assembly 220 rotates along with the second rotating shaft 212 and can move along the axial direction of the second rotating shaft 212 under an axial acting force. The second optical member 230 is mounted on the rotating assembly 220 and is used for transmitting light to or receiving light from the scalp, and an insertion structure for inserting hair is disposed at a side of the second optical member close to the scalp. The second optical member 230 may be one or more.

Specifically, when the optical module 200 is applied to a transcranial light modulation and control device or a near-infrared spectral brain function imaging device, the fixed housing 310 may be a part of the transcranial light modulation and control device or the near-infrared spectral brain function imaging device, and the number of the optical modules 200 may be multiple and may be set corresponding to a brain function region of the brain. The stationary housing 310 may directly form or be part of the helmet of the optical head applicator.

The rotating assembly 220 has a certain interval with the fixed shell 310 under the action of self gravity, and under the condition of not being interfered by external force, the rotating assembly 220 can only do rotating motion to stir hair, and the rotation of the rotating assembly 220 is interfered by external force, for example, under the condition that the pressure of the rotating assembly 220 and the scalp is increased due to the rotation, the rotating assembly 220 can cause discomfort of a user if the rotating assembly 220 continues to rotate at the moment. Therefore, under the condition that the rotating assembly 220 is interfered by external force, the rotating assembly 220 is moved in the direction close to the fixed housing 310 by the axial acting force so as to be far away from the head of the user, thereby achieving the effect of force leakage and avoiding discomfort caused to the user.

Specifically, the second shaft 212 can be rotated by the driving member 211 of the power assembly 210, and can also be rotated by manual operation of a user to rotationally shift hair. The driving member 211 and the second rotating shafts 212 may have a one-to-one correspondence relationship, that is, each second rotating shaft 212 may rotate independently, that is, the fitting degree between the second optical member 230 corresponding to the second rotating shaft 212 and the scalp may be adjusted independently, so as to locally adjust the acting force between the second optical member 230 and the scalp, thereby achieving the purposes of rotating and avoiding the user from generating discomfort.

Specifically, the fixed housing 310 may be understood as a stationary part, and the driving member 211 may be provided on the fixed housing 310 when the second rotating shaft 212 is rotated by the driving member 211.

Specifically, the second optical member 230 may include an infrared LED lamp, or other fiber optic probe, an optical waveguide member, or the like capable of guiding light to irradiate the head of the user. The second optical member 230 is provided with an insertion structure, such as a light guide 240, for inserting hair between hairs, on a side close to the scalp.

According to the utility model, through the matching between the second rotating shaft 212 and the second transmission part 221 of the optical module 200, the rotating assembly 220 of the optical module 200 can rotate along with the second rotating shaft 212 and can move along the axial direction of the second rotating shaft 212, so that the hair can be rotationally stirred, the light emitted by the optical component can be directly irradiated onto the scalp of a user, the light propagation rate is improved, the technical problem that the light emitted by the optical component is blocked by the hair in the prior art, so that the light propagation rate is reduced is solved, an ideal treatment effect is achieved, and the brain function can be better improved.

In some embodiments, the portion of the second rotating shaft 212 connected to the second transmission part 221 is formed with an external spline structure; the second transmission part 221 is configured as an internal spline structure. The structural design of the inner spline structure and the outer spline structure has the advantages of stable transmission and good guidance quality.

In some embodiments, the second rotating shaft 212 is formed with a plurality of third protrusions along a radial direction thereof, sliding grooves are formed between adjacent third protrusions along an axial direction of the second rotating shaft 212, and the second transmission part 221 has a fourth protrusion configured to be slidably received in the sliding grooves and abut against the third protrusions.

In some embodiments, as shown in fig. 4, the rotating assembly 220 includes a first assembly member 222 and a second assembly member 223 disposed on a side of the first assembly member 222 away from the fixed housing 310, the first assembly member 222 is sleeved outside the second rotating shaft 212, the second transmission portion 221 and the second optical member 230 are disposed on the second assembly member 223, and the second assembly member 223 is mounted on the fixed housing 310 in a manner that the second assembly member 223 can move relative to the fixed housing 310 in a direction parallel to the second rotating shaft.

Specifically, the power assembly 210 (including the first and second

fitting parts

222 and 223 described above) and the second optical member 230 may be relatively close to or far from the stationary housing 310, and the movement direction may be parallel to the axial direction of the second rotating shaft 212.

Specifically, the second optical member 230 may be disposed on a side of the second assembly 223 adjacent to the scalp. A light guide member 240 for guiding the light emitted from the second optical member 230 is further included, thereby guiding the light and increasing the light transmission efficiency.

In some embodiments, the optical module 200 further includes a reset element 224, one end of the reset element 224 abuts against the fixed housing 310, and the other end abuts against the rotating element 220, for applying a force to the rotating element 220 to make it away from the fixed housing 310.

As shown in fig. 4, the reset element 224 may be a spring, one end of which abuts against the fixed housing 310 and the other end of which abuts against the second assembly element 223. The first fitting 222 is located on the side of the spring that faces into the vertical page.

In addition, as shown in fig. 5, the reset element 224 may be a spring, and one end of the reset element may abut against the fixed housing 310, and the other end of the reset element abuts against the first assembly element 222, as long as the first assembly element 222 has a distribution structure at the lower end of the spring, and the spring can abut against the distribution structure.

Specifically, when the rotating assembly 220 can move according to the received axial force, and when the force generated by the scalp on the rotating assembly 220 in the axial direction is large, the rotating assembly 210 can properly release the force, so that a proper acting force can be maintained between the scalp and the second optical assembly 230, the scalp can be kept attached to the second optical assembly 230 without hindering the rotation of the rotating assembly 220, and the user does not feel uncomfortable. The distance of the upward movement may be very small, as long as the purpose of relieving the force without leaving the scalp is achieved.

In some embodiments, as shown in fig. 6, a plurality of limiting grooves 311 are formed on the fixing housing 310, the second assembly member 223 includes limiting rods 225 respectively extending into the limiting grooves 311, and the extending ends of the limiting rods 225 are provided with engaging portions 226. The stop lever 225 can move up with the rotating assembly 220 as required.

Specifically, the limiting grooves 311 may be formed in a semicircular arc shape, the centers of circles corresponding to the limiting grooves 311 are the same, and the axis of the output shaft of the driving member 211 passes through the center of circle. The number of the limiting grooves 311 is plural, and the number of the limiting grooves 311 shown in fig. 6 is three, which is not specifically limited in the present application.

Therefore, the driving member 211 can drive the second rotating shaft 212, the rotating assembly 220 and the second optical member 230 to rotate forward or backward within a small angle range, so as to open hair and improve light transmission rate.

It should be noted that, although the distribution area of the second optical member 230 or the substrate size thereof in the above-mentioned drawings is identical to or slightly smaller than the size of the mounting hole, in other embodiments, the distribution area of the second optical member 230 or the substrate size thereof is not limited to the area corresponding to the mounting hole, and may exceed the projection area of the mounting hole, for example.

The embodiment of the present invention also provides another head optical applying apparatus 300 equipped with the optical module 200.

The helmet body may be formed of the fixed shell 310, or the helmet body includes the fixed shell 310. The helmet body is provided with a plurality of mounting holes for mounting the optical module 200. The plurality of mounting holes can be distributed in groups, and each group of mounting holes corresponds to one brain functional region. The optical module 200 is mounted in the mounting hole. Each optical module 200 can independently adjust the fit to the scalp.
