It should also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense, unless specifically so defined herein.

[0040] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification where appropriate.

[0041] According to some embodiments of the present disclosure, a head optical application device 100 is provided, as shown in Figures 1 to 14 The head optical application device 100 includes a first base 110, an optical member 120, a second base 130, expandable members 140, and a driving assembly 150. The first base 110 is configured to mount the optical member 120. The optical member 120 is configured to transmit light to the scalp. The second base 130 is configured to mount at least two expandable members 140 on a distal side. The driving assembly 150 is configured to cause each expandable member 140 to converge or diverge from each other on a distal side of the optical member 120.

[0042] It should be noted that the device provided with the head optical application device 100 can be worn on the head of a user by an operator, the optical member 120 corresponds to the scalp of the user, the proximal side of the present disclosure is the side close to the operator and away from the scalp of the user, the distal side is the side close to the scalp of the user, the proximal end is the end away from the scalp of the user, the distal end is the end close to the scalp of the user, and the proximal side and the distal side referred to below are intended to have this meaning.

[0043] Specifically, the head optical application device 100 includes but is not limited to being applied to the transcranial light regulation device 200. The optical member 120 is provided with emitting light, and the light can be infrared light capable of penetrating the skull. The optical member 120 can be an LED lamp, an optical fiber, a laser, or any optical member capable of emitting light. When the head optical application device 100 is applied to the transcranial light regulation product, the optical member 120 is mainly used to emit light to the scalp to improve the brain function of the user. The present disclosure does not specifically limit the function of the optical member 120 and the adaptive relationship between the plurality of optical members 120, and can adopt the optical member 120 with corresponding functions according to the technical field to which the head optical application device 100 is applied, so as to improve the irradiation rate of the scalp of the user.

[0044] The present disclosure does not specifically limit the number and specific structure of the extendable members 140, which can only be able to push away the hair between the optical member 120 and the scalp of the user. Preferably, the extendable members 140 can be arranged around the optical member 120, or can be arranged in pairs on opposite sides of the optical member 120 to achieve a better effect of pushing away the hair, so that the light emitted by the optical member 120 can directly irradiate the scalp. The extendable member 140 can be any shape or structure capable of achieving the effect of pushing away the hair, such as an arc-shaped plate, a triangular plate, a rectangular plate, or other shapes. The structure of each extendable member 140 in the drawings is only an example, and the present disclosure is not limited thereto.

[0045] Specifically, each extendable member 140 has a gathering state in which the distal ends thereof are gathered to each other, and an unfolding state in which the distal ends thereof are unfolded to each other. When the device provided with the head optical application device 100 is worn on the head of a user, the distal ends of each extendable member 140 are in the gathering state, and the cross-sectional area of the distal ends of each extendable member 140 can be as small as possible to facilitate insertion into the hair. After the user wears the device, the distal ends of the extendable members 140 maintain a close fit with the scalp of the user, so that when the driving assembly 150 works to unfold the distal ends of each extendable member 140 to each other, the extendable member 140 can drive the hair in the irradiation area of the optical member 120 to move away from the area, thereby achieving the purpose of pushing away the hair and improving the light propagation rate.

[0046] In some embodiments, when the various expandable members 140 are in the converged state, each expandable member 140 may be arranged in a conical shape, and the tip of the cone is arranged in relation to the light-emitting or light-receiving optical path of the optical member 120, for example, arranged on the optical path, so that when the various expandable members 140 are switched to the unfolded state, the hair on the optical path of the optical member 120 is pushed aside to improve the light propagation rate along the optical path relative to the scalp.

[0047] Specifically, this disclosure does not specifically limit the shape and material of the first base 110 and the second base 130. Their shapes can be any shape, such as circular, rectangular, or block-like, as long as they can support the corresponding components. Furthermore, the structural design of the first base 110 and the second base 130 should minimize their space occupation and be made of materials with high structural strength and light weight. This is to maintain stable installation while reducing pressure on the user's head during wear, thus improving the user experience. (Specific details can be found in the following text.) Figure 1 and Figure 5 As shown, Figure 1 The first base 110 and the second base 130 shown are both rectangular plates. Figure 5 The first base 110 and the second base 130 shown are both circular plates. The structure of the first base 110 and the second base 130 can be selectively designed according to the specific structural layout of the head optical application device 100.

[0048] In some embodiments, the drive assembly 150 may include a pneumatic mechanism, an electromagnetic control mechanism, or other devices that can operate powered by a power source. This disclosure does not specifically limit its functionality. The drive assembly 150 simply needs to operate to switch the distal ends of each extendable member 140 between a converged and deployed state. The drive assembly 150 can also electrically or manually control the degree of deployment or convergence of each extendable member 140, making operation convenient and allowing adjustment of the extension degree of the extendable members 140 according to actual conditions, thereby improving the flexibility of the head optical application device 100.

[0049] This disclosure improves the problem of low light propagation caused by hair obstruction by using a drive assembly 150 that enables the distal ends of each expandable element 140 to be inserted into the user's hair in a converged state, and after insertion, the distal ends of the expandable elements 140 can be deployed to push aside the hair blocking light. Furthermore, it improves the usability of the transcranial light modulation device 200 using this head optical application device 100, allowing the light emitted from the optical component 120 of the optical application device to directly illuminate the user's scalp and penetrate the skull, thereby better improving brain function.

[0050] In some embodiments, the head optical application device 100 further comprises a transmission mechanism 160 connected with the driving assembly 150, wherein the transmission mechanism 160 is configured to convert the driving in the first direction applied by the driving assembly 150 into the expansion of each expandable member 140, and convert the driving in the second direction applied by the driving assembly 150 into the gathering of each expandable member 140.

[0051] Specifically, the first direction is a direction towards the scalp, and the second direction is a direction away from the scalp. The transmission mechanism 160 can be arranged between the driving assembly 150 and each expandable member 140, the driving assembly 150 can drive the movement of the expandable member 140 by acting on the first base 110, or directly drive the movement of each expandable member 140 through the transmission mechanism 160, wherein the transmission mechanism 160 can be connected with the first base 110, or connected with each expandable member 140, or maintain a close abutting interaction relationship with each expandable member 140, and the arrangement relationship between the driving assembly 150, the transmission mechanism 160, the first base 110 and each expandable member 140 can be combined with each other without conflict. The specific structure adopted by each embodiment of the present disclosure will be described below, and will not be described here.

[0052] In some embodiments, the driving in the first direction applied by the driving assembly 150 is associated with the expanded state of each expandable member 140, and the driving in the second direction applied by the driving assembly 150 is associated with the gathered state of each expandable member 140. The movement of the driving assembly 150 can also be associated with the movement of the optical member 120, further improving the illumination rate on the scalp, thereby achieving better treatment effect or measurement result. For example, when the driving assembly 150 applies driving in the first direction, it can also drive the optical member 120 to move in the first direction synchronously, and when the driving assembly 150 applies driving in the second direction, it can also drive the optical member 120 to move in the second direction synchronously, so that when the optical member 120 moves in the direction close to the scalp, the distal end of each expandable member 140 expands to push away the hair between the optical member 120 and the scalp, which can shorten the distance between the optical member 120 and the scalp, and also push away the obstructing hair at the same time, achieving a better effect of emitting light.

[0053] In some embodiments, the transmission mechanism 160 can adopt mechanical transmission, which can specifically include one or more of a gear transmission assembly, a chain transmission assembly, and a connecting rod transmission assembly. In the following part of the embodiments, the structure of the transmission mechanism 160 will be described by taking the connecting rod transmission as an example, but the present disclosure is not limited thereto.

[0054] In some embodiments, the drive assembly 150 is further configured to drive the first base 110 to move in a first direction or a second direction. The transmission mechanism 160 may be configured to interact with the first base 110 and the respective expandable members 140 in such a way that movement of the first base 110 in the first direction is converted into the unfolding of the respective expandable members 140, and movement of the first base 110 in the second direction is converted into the convergence of the respective expandable members 140.

[0055] In some embodiments, the first base 110 is capable of moving in a first direction or a second direction under the action of the driving component 150, while the second base 130 is in a non-moving state. That is, the first base 110 can move relative to the second base 130 under the drive of the driving component 150. The first base 110 acts on the proximal ends of each expandable member 140 through the transmission mechanism 160, causing it to switch between an expanded state and a converged state.

[0056] This disclosure provides multiple embodiments for the aforementioned drive assembly 150 to drive the transmission mechanism 160 to move by driving the first base 110, thereby enabling the various expandable members 140 to switch between an extended state and a converged state. Specifically, it includes at least the embodiments described below, wherein the various technical features in the various embodiments can be combined with each other without conflict to form other technical solutions that can achieve the movement of the transmission mechanism 160 by driving the first base 110.

[0057] Example 1

[0058] like Figures 1 to 8 As shown, the transmission mechanism 160 includes a connecting rod 161, with both ends of the connecting rod 161 pivotally connected to the first base 110 and the expandable member 140, respectively. The proximal end of the expandable member 140 is pivotally connected to the first end of the connecting rod 161, preventing the expandable member 140 from bending laterally or inward during expansion, thus ensuring a better flicking effect. The second end of the connecting rod 161 is pivotally connected to the first base 110, allowing the expandable member 140 to pivot via the connecting rod 161 as the first base 110 moves. The driving assembly 150 acts on the first base 110 to drive the first base 110 to move in a first direction or a second direction.

[0059] For example, such as Figures 1 to 4As shown, the optical member 120 can be multiple, the first base 110 is a rectangular plate, and the first base 110 has a first length direction along its long edge. The multiple optical members 120 are arranged in sequence along the first length direction, and the multiple extendable members 140 can be arranged in pairs on opposite sides of the optical member 120 along the first length direction. The number of extendable members 140, the number of optical members 120, and the arrangement manner are not limited in the present disclosure, as long as the emitted light and the hair-pushing effect are good. In addition, the first base 110 can have an arc surface that matches the arc of the user's head, so that the optical member 120 arranged thereon can further approach the scalp.

[0060] In some embodiments, as shown in Figure 1 and Figure 2 The extendable member 140 has an extension body 143 and a first arc-shaped portion 144 arranged at the distal end of the extension body 143. The extension body 143 can be an arc-shaped plate, Figure 1 The number of extendable members 140 shown in the figure is two, and of course multiple extendable members 140 can also be arranged along the first direction. The figure only illustrates one extendable member 140 arranged on one side of the optical member 120, and the present disclosure is not limited thereto. As shown in Figure 1 The shapes of the extension bodies 143 of the two extendable members 140 arranged on opposite sides of the optical member 120 are configured to expand outwardly relative to each other, so as to facilitate the movement of the two extendable members 140 to the unfolded state.

[0061] As shown in Figure 1 and Figure 2 The arc-shaped plate-shaped extension body 143 can press the pushed hair during the unfolding of the extendable member 140, so as to achieve a better hair-pushing effect.

[0062] In some embodiments, multiple pushing portions can be outwardly extended at the distal end of the extension body 143, and the multiple pushing portions are arranged along the first length direction. The first arc-shaped portion 144 is arranged at the distal end of the pushing portion. It can be understood that the first arc-shaped portion 144 is the portion that contacts the scalp of the user, and the arc shape can improve the discomfort of the user when using the optical application device and improve the wearing comfort. In addition, the first arc-shaped portion 144 can be made of a flexible material, so that when the first arc-shaped portion 144 contacts the scalp of the user and when the extendable member 140 is extended, the first arc-shaped portion 144 will not cause excessive pressure on the scalp of the user and will not cause aching.

[0063] In some embodiments, continuing to combine Figure 1 and Figure 2The distal end of the expandable member 140 is inwardly retracted to form a stepped portion 147, which is located on the opposite sides of the first arc-shaped portion 144. When the device provided with the head optical application device 100 is worn, the first arc-shaped portion 144 abuts against the user's scalp, and the distal side of the stepped portion 147 has a spacing from the user's scalp for accommodating hair, so as to be able to compress the hair that is pushed away during the expansion of each expandable member 140, thereby achieving a better hair pushing effect.

[0064] Exemplarily, as shown in Figures 5 to 8 , the optical member 120 can be one or more, and the first base 110 and the second base 130 are both circular plates. When the optical member 120 is multiple (as shown in Figure 5 and Figure 6 ), one optical member 120 is arranged at the middle of the first base 110, and the other optical members 120 are arranged around the optical member 120 at the middle. When the optical member 120 is one (as shown in Figure 7 and Figure 8 ), the optical member 120 is arranged at the middle of the first base 110.

[0065] In some embodiments, continuing to combine Figures 5 to 8 , the plurality of expandable members 140 are arranged around the one or more optical members 120, Figure 5 and Figure 7 , the number of the expandable members 140 shown in the drawings is six, which is only an example, and the disclosure does not specifically limit the number of the expandable members 140.

[0066] In some embodiments, due to the different head shapes of users, it can happen that the distal end of the expandable member 140 cannot completely abut against the scalp during the expansion of the expandable member 140. Therefore, the outer side of each expandable member 140 can be arranged with a comb tooth portion 142 at intervals (as shown in Figure 5 and Figure 6 ), which can further push the hair that is pushed away along the expansion direction when the expandable member 140 is expanded outward, so as to avoid the pushed hair from approaching the area between the optical member 120 and the scalp, thereby achieving a better hair pushing effect. The comb tooth portion 142 can be in various shapes such as a sphere or a cuboid, which is not specifically limited herein.

[0067] In some embodiments, the cross-sectional area of the expandable member 140 gradually decreases from the proximal side to the distal side, in combination with Figures 5 to 8The expandable member 140 can be arc-shaped plate, triangular plate or other shapes, and the proximal cross-sectional area of the expandable member 140 gradually decreases to the distal cross-sectional area, so that the proximal end of the expandable member 140 can be stably pivoted with the second base 130 and the transmission mechanism 160, and the distal end of the expandable member 140 can be inserted into the user's hair.

[0068] In some embodiments, as shown in Figures 1 to 8 The second base 130 has a base plate 131 and a plurality of first mounting seats 132 protruding from the base plate 131, and the expandable member 140 is pivoted to the first mounting seat 132. The second base 130 is further provided with a through slot 133, and the driving assembly 150 is connected with the first base 110 through the through slot 133.

[0069] In some embodiments, the base plate 131 can be integrally formed with the first mounting seat 132 or detachably connected. When the base plate 131 is detachably connected with the first mounting seat 132, the number of the first mounting seat 132 and the expandable member 140 pivoted to the first mounting seat 132 can be adjusted according to the hair volume of the user, that is, when the user has more hair, the number of the first mounting seat 132 and the expandable member 140 is increased, and when the user has less hair, the number of the first mounting seat 132 and the expandable member 140 is reduced.

[0070] Embodiment two

[0071] As shown in Figures 11 to 14 The head optical application device 100 can include a biasing member 170 for gathering the proximal ends of the plurality of expandable members 140, and the plurality of expandable members 140 are pivoted to the second base 130, and the second base 130 is provided with a through hole 134 allowing the optical member 120 to pass through.

[0072] Specifically, the biasing member 170 can be a member with inwardly retracting elastic force, which can be sleeved on the proximal outer side of the plurality of expandable members 140, or embedded on the proximal inner side of the plurality of expandable members 140, or sequentially inserted into the proximal sides of the plurality of expandable members 140. Figures 11 to 14 The biasing member 170 is sleeved on the proximal outer side of the plurality of expandable members 140 as shown in the figure below, which is taken as an example in the following description, but the present disclosure is not limited thereto, and the biasing member 170 can act on the proximal ends of the plurality of expandable members 140 to keep them gathered. Figure 11 and Figure 12 In order to stably sleeve the biasing member 170 on the expandable member 140, a recess can be provided on the proximal outer side of each expandable member 140, and the biasing member 170 is embedded in the plurality of recesses, so as to facilitate the installation of the biasing member 170 and the positioning of the biasing member 170.

[0073] In some embodiments, the second base 130 described above can be a ring-shaped sleeve, a rectangular sleeve or any other shape, and the shape of the through hole 134 corresponding thereto can also be arbitrary, as long as the optical member 120 can move out of the through hole 134 in the first direction. Figure 11 The second base 130 and the through hole 134 shown in the middle of the figure are a ring-shaped sleeve and a circular hole, which are only examples, and the present disclosure is not limited thereto.

[0074] In some embodiments, the outer periphery of the second base 130 described above can be provided with a plurality of ears for pivoting the expandable members 140, so that the expandable members 140 cannot be bent inward or laterally, which can affect the hair pulling effect. The distal end of each expandable member 140 in the embodiment can also be provided with the first arc-shaped portion 144 described above. The first arc-shaped portion 144 in this embodiment can be made of a flexible material, so that when the first arc-shaped portion 144 contacts the user's scalp and when the expandable member 140 is expanded, it will not cause excessive pressure on the user's scalp and cause pain, and the arc-shaped surface can further improve comfort.

[0075] In some embodiments, as shown in Figure 13 and Figure 14 , the second base 130 described above is externally provided with a second mounting seat 167, and each expandable member 140 is pivoted to the second mounting seat 167. Among them, the second mounting seat 167 can make the head optical application device 100 stably installed on the equipment corresponding thereto, such as the transcranial light regulation equipment 200.

[0076] In some embodiments, as shown in Figures 11 to 14 , the transmission mechanism 160 includes an action member 162 connected to the driving assembly 150 and the first base 110. The action member 162 has an arc-shaped tapered portion 163 extending from its distal side to its proximal side. The proximal side of the expandable member 140 is attached to the periphery of the arc-shaped tapered portion 163 under the action of the biasing member 170.

[0077] In some embodiments, continuing to combine Figures 11 to 14 , the action member 162 extends in the direction of the scalp to form its length direction, and its proximal side is connected to the driving assembly 150, and its distal side is connected to the first base 110. Since the biasing member 170 described above can gather the proximal ends of each expandable member 140, when the action member 162 advances in the first direction or retreats in the second direction, the biasing member 170 can make the proximal end of the expandable member 140 tightly abut against the outer wall of the arc-shaped tapered portion 163, so that the proximal end of the expandable member 140 can move relatively close or relatively close along the outer wall of the arc-shaped tapered portion 163.

[0078] In some embodiments, as shown in Figure 11 and Figure 12As shown, the acting member 162 is formed with a stop portion 164 on the proximal side of the arc-shaped tapered portion 163, and the driving assembly 150 is connected to the proximal side of the stop portion 164. The stop portion 164 can be integrally formed with the arc-shaped tapered portion 163 to maintain a relatively stable positional relationship therebetween.

[0079] Specifically, when the expandable member 140 is in the expanded state, the proximal end of the expandable member 140 can abut against the stop portion 164 to limit the movement of the acting member 162 in the first direction, thereby preventing the optical member 120 located on the distal end of the acting member 162 from excessively abutting against the user's scalp, thus causing discomfort to the user.

[0080] In some embodiments, as shown in Figure 11 and Figure 12 The proximal side of the expandable member 140 is formed with an arc-shaped cylindrical portion 141, which is configured such that at least part of the arc-shaped inner circumferential surface thereof is adapted to abut against the circumferential surface of the acting member 162.

[0081] The arc-shaped inner circumferential surface of the arc-shaped cylindrical portion 141 abuts against the outer surface of the acting member 162, thereby reducing the abutment area and the frictional force during sliding, facilitating the extension and retraction movement of the acting member 162.

[0082] In some embodiments, as shown in Figure 15 and Figure 16 The driving assembly 150 includes a gas assembly 151 and a pushing assembly 152 capable of extending and retracting under the action of the gas assembly 151, and the output end of the pushing assembly 152 is connected to the transmission mechanism 160 or the first base 110.

[0083] Specifically, the gas assembly 151 and the pushing assembly 152 included in the driving assembly 150 can be applied to any embodiment in the present disclosure, Figure 15 only the gas assembly 151 is applied to the second embodiment as an example to describe the specific structure of the pneumatic assembly, and the present disclosure is not limited thereto.

[0084] In some embodiments, the gas assembly 151 can provide a gas to apply a force in the first direction to the pushing assembly 152, or can withdraw the gas to move the pushing assembly 152 in the second direction, so that the pushing assembly 152 can move while pushing the transmission mechanism 160 or the first base 110 to move.

[0085] In some embodiments, the pushing assembly 152 includes a sleeve 153, a telescopic rod 154 slidingly arranged in the sleeve 153, and an elastic return member 155 arranged in the sleeve 153 and sleeved on the telescopic rod 154, and the proximal side of the sleeve 153 is provided with an interface 156 connected to the gas assembly 151.

[0086] In some embodiments, the sleeve 153 is provided with a through hole on a side of the acting member 162, through which the telescopic rod 154 passes, and one end of the telescopic rod 154 passing through the through hole is connected with the acting member 162.

[0087] Further, as shown in Figure 16 , the telescopic rod 154 has a shaft portion and a seat body provided on a proximal end of the shaft portion, the seat body is sealingly connected with the inner wall of the sleeve 153, and the inner cavity of the sleeve 153 is divided into an upper chamber and a lower chamber by the seat body, the lower chamber is connected with the gas assembly 151, and the upper chamber is provided with a hole communicating with the outside, so that the gas in the upper chamber can be discharged through the hole when the telescopic rod 154 moves in the first direction. The elastic return member 155 is sleeved on the outer side of the shaft portion, and one end thereof abuts against the distal side of the seat body, and the other end thereof abuts against the distal inner wall of the sleeve 153.

[0088] In some embodiments, when the head optical application device 100 provided with the above-mentioned driving assembly 150 is applied to the transcranial light regulation equipment 200, the corresponding transcranial light regulation equipment 200 can be provided with a main pipeline and branch pipelines respectively connected with each head optical application device 100, the gas assembly 151 is connected with the main pipeline, the main pipeline supplies gas to each branch pipeline, and the flow direction of the gas is controlled by the electromagnetic valve, so that the gas enters or is discharged from the sleeve 153, and finally acts on the telescopic rod 154.

[0089] In some embodiments, the gas assembly 151 includes a switch member 157 arranged in a left-right slidable manner, as shown in Figure 15 and Figure 16 , the arrows in the figure show the flow direction of the gas, when the switch member 157 moves away from the pushing assembly 152 (as shown in Figure 16 ), the gas can enter the sleeve 153 from the gas assembly 151, at this time, the pushing assembly 152 acts on the acting member 162 to keep each expandable member 140 in the unfolded state, during the movement of the switch member 157 towards the pushing assembly 152, the gas pressure in the gas assembly 151 reaches the atmospheric pressure, under the action of the elastic return member 155, the pushing assembly 152 moves in the second direction, so that each expandable member 140 is switched from the unfolded state to the gathered state, at this time, the flow direction of the gas is shown by the arrow direction in Figure 15 . It can be understood that the gas in the sleeve 153 can also be discharged through other pipelines to make the pushing assembly 152 move in the second direction, so as to realize the switching of each expandable member 140 from the unfolded state to the gathered state.

[0090] Embodiment Three

[0091] In some embodiments, the driving assembly 150 can be configured to directly drive the transmission mechanism 160 to expand or contract the expandable members 140. That is, the driving assembly 150 is directly connected with the transmission mechanism 160 to directly drive the transmission mechanism 160 to move. The transmission mechanism 160 can be mounted on the first base 110 or the second base 130, and can move to drive the expandable members 140 to move.

[0092] In some embodiments, as shown in Figure 9 and Figure 10 , the transmission mechanism 160 includes a connecting platform 165 and a plurality of linkage assemblies 166 mounted on the connecting platform 165 and the second base 130, and the expandable members 140 are pivotally connected with the linkage assemblies 166. The driving assembly 150 is further configured to drive the connecting platform 165 to move close to or away from the second base 130.

[0093] In some embodiments, the first base 110 and the second base 130 are both located at the distal side of the connecting platform 165, and the connecting platform 165 is movably spaced apart from the second base 130. The linkage assemblies 166 can include a plurality of transmission links pivotally connected in sequence. The driving assembly 150 directly acts on the connecting platform 165 to drive the connecting platform 165 to move relative to the second base 130. The connecting platform 165 drives the expandable members 140 on the second base 130 to switch between the expanded state and the contracted state through the plurality of transmission links.

[0094] In some embodiments, the second base 130 protrudes a plurality of third mounting seats 135 pivotally connected with the linkage assemblies 166 and the expandable members 140. The second base 130 and the first base 110 can be the same base, and there is no relative movement between the two. The optical member 120 can be arranged on the distal side of the second base 130.

[0095] In some embodiments, the outer side of the expandable members 140 is spaced apart and arranged with a plurality of comb teeth 142.

[0096] Specifically, the outer side of the expandable members 140 in each embodiment of the present disclosure can be provided with the comb teeth 142. When the expandable members 140 are expanded outward, the comb teeth 142 can further pick up the hair that is brushed away along the direction of expansion, so as to avoid the hair that is brushed away from approaching the area between the optical member 120 and the scalp, thereby achieving a better effect of brushing away the hair. The comb teeth 142 can be in various shapes such as spherical shape, cuboid, etc., which are not limited herein.

[0097] In some embodiments, as shown in Figures 5 to 10As shown, the plurality of expandable members 140 are arranged around the optical member 120. The distal ends of the plurality of expandable members 140 around the optical member 120 can gradually expand outward to achieve a better effect of pushing the hair between the optical member 120 and the scalp, so that the light emitted by the optical member 120 can directly irradiate on the scalp.

[0098] In some embodiments, as shown in Figures 1 to 4 As shown, the optical member 120 is a plurality of optical members 120 arranged in sequence along a first length direction, and the plurality of expandable members 140 are arranged in pairs on opposite sides of the optical member 120 along the first length direction. And the plurality of optical members 120 can be arranged along a first width direction perpendicular to the first length direction.

[0099] The distance between the optical members 120 and the number of arrangements are not limited by the present disclosure, and can be designed according to the application scenario of the head optical application device 100.

[0100] In some embodiments, as shown in Figures 1 to 16 As shown, the expandable member 140 has an expansion body 143 and a first arc-shaped portion 144 arranged at the distal side of the expansion body 143. The first arc-shaped portion 144 is the part that contacts the user's scalp, which is arc-shaped to improve the user's discomfort when using the optical application device and improve the comfort of wearing.

[0101] In some embodiments, as shown in Figures 9 to 12 As shown, the first arc-shaped portion 144 is made of a flexible material, and the flexibility of the material of the first arc-shaped portion 144 is greater than the flexibility of the material of the expansion body 143. The first arc-shaped portion 144 is made of a flexible material, which can make it contact the user's scalp and expand the expandable member 140 without causing excessive pressure on the user's scalp and causing pain. The expansion body 143 as a whole can be made of a flexible material or a rigid material, or a combination of flexible and rigid materials, which is less flexible than the first arc-shaped portion 144, so that the expandable member 140 can be smoothly expanded under the drive of the driving assembly 150, avoiding the expansion body 143 from being bent and affecting the hair pushing effect.

[0102] In some embodiments, as shown in Figure 17 As shown, the expandable member 140 includes a first body 145 and a second body 146 arranged on the distal side of the first body 145, and the flexibility of the material of the second body 146 is greater than the flexibility of the material of the first body 145.

[0103] In some embodiments, the second body 146 is closer to the user's scalp relative to the first body 145, and the second body 146 is made of a material with relatively large flexibility to ensure comfort when it is in contact with the user's scalp, and the first body 145 is made of a material with relatively high hardness to further ensure smooth relative expansion of the expandable member 140 during expansion, without inward bending or lateral bending, which may affect the hair growth effect.

[0104] In some embodiments, the flexibility of the first arc-shaped portion 144 can be greater than that of the second body 146 to further improve the comfort of the user.

[0105] In some embodiments, as shown in Figures 1 to 16 , the cross-sectional area of the expandable member 140 gradually decreases from the proximal side to the distal side, so that the distal end of the expandable member 140 can be smoothly inserted into the hair gap and abut against the user's scalp.

[0106] In some embodiments, the expandable member 140 is made of a transparent material that can transmit light to prevent blocking the light emitted or received by the optical member 120.

[0107] In some embodiments, as shown in Figure 1 and Figure 2 , the distal end of the expandable member 140 is inwardly retracted to form a stepped portion 147. It should be noted that the distal end of the expandable member 140 in each embodiment of the present disclosure can be inwardly retracted to form a stepped portion 147, and is not limited to the technical solution applied in Embodiment One, Figure 1 and Figure 2 , the stepped portion 147 shown is only an example.

[0110] In some embodiments, a plurality of elastic members, such as springs 250 (as shown inFigure 19 The head optical application device 100 can be adapted to different head shapes of users under the action of the elastic member and / or the elastic layer when the user wears the transcranial light regulation device 200.

[0111] The transcranial light regulation device 200 adopting the head optical application device 100 can realize that the distal end of each expandable member 140 can be inserted into the hair of the user in the gathered state, and the distal end of the expandable member 140 can push away the hair that blocks light in the unfolded state after being inserted, which improves the problem of low light propagation rate caused by the blocking of hair, and makes the transcranial light regulation device 200 achieve better use effect.

[0112] According to some embodiments of the present disclosure, a transcranial light regulation device 200 is also provided, as shown in Figure 20 and Figure 21 The transcranial light regulation device 200 includes the above-mentioned head optical application device 100, and an elastic cross-linking network 220 for installing a plurality of head optical application devices 100. The design of the above-mentioned elastic cross-linking network 220 enables the user to adapt to different head shapes when wearing, and the elasticity of the elastic cross-linking network 220 can make the head optical application device 100 tightly abut against the scalp. Even in the face of various different head shapes, the tension applied at the corresponding position of the elastic cross-linking network 220 can be transmitted and expanded to other positions of the elastic cross-linking network 220 by the cross-linking topological structure of the elastic cross-linking network 220, so that the elastic cross-linking network 220 can be tightly attached to the scalp of any head shape, thereby facilitating the subsequent expansion of the expandable member 140 to push away the hair. And the above-mentioned head optical application device 100 installed on the elastic cross-linking network 220 can have a certain degree of freedom, so as to be adaptively adjusted according to the head shape of the user, while keeping the head optical application device 100 in close contact with the scalp.

[0113] In some embodiments, the above-mentioned elastic cross-linking network 220 can include a plurality of cross-linked elastic bands, and the plurality of elastic bands form a containing cavity around the head of the user. For example, in combination with Figure 20 The above-mentioned elastic cross-linking network 220 can include a ring-shaped body and a band body connected to opposite sides of the ring-shaped body, the band body corresponds to the top of the head of the user, and the ring-shaped body is arranged around the head of the user. A plurality of head optical application devices 100 can be arranged on the above-mentioned band body and ring-shaped body. The above-mentioned is only an example of the specific structure of the elastic cross-linking network 220, and the present disclosure is not limited thereto.

[0114] Exemplarily, the above-mentioned elastic cross-linking network 220 can be integrally formed, or can be made by connecting a plurality of elastic bands, and the present disclosure does not make specific limitation thereto.

[0115] According to some embodiments of the present disclosure, a transcranial light regulation device 200 is also provided, as shown in Figure 22 and Figure 23 The transcranial light regulation device 200 includes the head optical application device 100 described above, and further includes an elastic mesh network 220 and a housing 210 for mounting the elastic mesh network 220, and the plurality of head optical application devices 100 are arranged on the elastic mesh network 220.

[0116] The housing 210 described above can be made of a relatively hard material so that it can maintain a certain shape and be convenient for the user to wear the transcranial light regulation device 200. At the same time, the plurality of head optical application devices 100 are arranged on the elastic mesh network 220, so that the head optical application devices 100 can tightly abut against the scalp under the action of the elastic mesh network 220, which is beneficial to the subsequent expansion of the expandable member 140 to push away the hair and improve the light irradiation rate on the target area on the scalp. Moreover, the elastic mesh network 220 can adapt to the head shape of different users when the user wears it. Through the above structure, the transcranial light regulation device 200 has the advantages of convenient wearing, good light irradiation effect, and the ability to adapt to the head shape of different users.

[0117] In some embodiments, as shown in Figures 22 to 24 The housing 210 is provided with a plurality of mounting members 230 for mounting the elastic mesh network 220, and the end of the mounting member 230 in the first direction towards the scalp has a flange, and the second direction side of the flange away from the scalp has a ring-shaped recess 240 with a predetermined length, so that the elastic mesh network 220 can be circumferentially sleeved on the ring-shaped recess 240, and can provide an expansion allowance for the sleeved elastic mesh network 220.

[0118] In some embodiments, the elastic mesh network 220 described above can include a plurality of thin sheet-shaped elastic bands, which are sleeved on the mounting member 230 and embedded in the ring-shaped recess 240. The thickness direction of the elastic mesh network 220 can be understood as the direction towards the scalp. Through the gap cooperation between the ring-shaped recess 240 and the elastic mesh network 220, the elastic mesh network 220 can provide more expansion allowance when it is expanded to adapt to the head shape of the user, thereby increasing the deformation space of the elastic mesh network 220.
