The first base 110 is configured to mount the optical member 120. The optical member 120 is configured to transmit light to or receive light from the scalp. The second base 130 is configured to distally mount at least two expandable members 140. The drive assembly 150 is configured to: the individual expandable members 140 are brought together or spread apart from each other on the distal side of the optical member 120.

It should be noted that the apparatus equipped with the head optical application device 100 can be worn by an operator on the head of a user, the optical member 120 corresponds to the scalp of the user, and the proximal side in the present disclosure refers to a side close to the operator and away from the scalp of the user, and the distal side refers to a side close to the scalp of the user, the proximal side refers to an end away from the scalp of the user, and the distal side refers to an end close to the scalp of the user.

Specifically, the above-mentioned optical head applying apparatus 100 includes, but is not limited to, the application to the transcranial light modulation device 200 or the near infrared device. The optical member 120 has a function of emitting light, which may be infrared light capable of penetrating the skull, or receiving light emitted from the scalp of the user, and the optical member 120 may be any optical member capable of emitting or receiving light, such as an LED lamp, an optical fiber, or a laser. When the head optical applying apparatus 100 is applied to a transcranial light modulation and control product, the optical member 120 is mainly used for emitting light to the scalp to improve the brain function of the user, and when the head optical applying apparatus 100 is applied to the near-infrared brain function imaging technology field, the optical member 120 capable of emitting light and the optical member 120 capable of receiving light can be simultaneously used for measuring the brain blood flow dynamics signal of the user. Of course, the head optical application device 100 may also be applied to other apparatuses, and is mainly used for receiving light emitted from the scalp, the present disclosure does not specifically limit the function of the optical member 120 and the fitting relationship between the plurality of optical members 120, and the optical member 120 having corresponding functions may be adopted according to the technical field to which the head optical application device 100 is applied, so as to improve the irradiation rate to the scalp of the user.

The number and specific structure of the expandable members 140 are not specifically limited in the present disclosure, and the expandable members 140 may be configured to pull the hair between the optical member 120 and the scalp of the user, and preferably, the expandable members 140 may be disposed around the optical member 120, or may be disposed on two opposite sides of the optical member 120 in pairs, so as to achieve a better hair pulling effect, so that the light emitted from the optical member 120 can directly irradiate the scalp, or receive the light emitted from the scalp. The expandable members 140 may be any shape or structure capable of achieving a hair-setting effect, such as an arc-shaped plate, a triangular plate, a rectangular plate, or other shapes, and the structure of each expandable member 140 in the drawings is only an example, and the disclosure is not limited thereto.

Specifically, each expandable member 140 has a gathered state in which the distal ends are gathered to each other, and a deployed state in which the distal ends are spread apart from each other, therebetween. When the apparatus to which the above-described cranial optical application device 100 is mounted is worn on the head of a user, the distal end of each expandable member 140 is in a gathered state, and the cross-sectional area of the distal end of each expandable member 140 can be minimized to facilitate insertion into the hair. After the user wears the device, the distal ends of the expandable members 140 are in close contact with the scalp of the user, so that when the driving assembly 150 works to expand the distal ends of the respective expandable members 140 to switch to the expanded state, the expandable members 140 can drive the hairs in the area irradiated by the optical member 120 to move away from the area, thereby achieving the purpose of opening the hairs and improving the light transmission rate.

In some embodiments, each expandable member 140 may be conically disposed when each expandable member 140 is in the gathered state, with the tip of the cone being disposed in relation to, e.g., on, the optical path of the light emitted or received by the optical member 120, so as to pluck the hair on the optical path of the optical member 120 to increase the rate of light propagation along the optical path relative to the scalp when each expandable member 140 is switched to the expanded state.

Specifically, the shape and material of the first base portion 110 and the second base portion 130 are not specifically limited in the present disclosure, and the shape of the first base portion 110 and the second base portion 130 may be any shape such as a circular plate shape, a rectangular plate shape, and a block shape, and it is sufficient to bear corresponding components, and the structural design of the first base portion 110 and the second base portion 130 should reduce the occupied space thereof as much as possible, and the first base portion and the second base portion are made of a material having strong structural strength and light weight, so as to be beneficial to maintaining the installation stability, and at the same time, reduce the pressure on the head of a user when wearing the head, and improve the use experience of the user. As can be seen in fig. 1 and 5 in particular, the first base 110 and the second base 130 shown in fig. 1 are both rectangular plate-shaped, and the first base 110 and the second base 130 shown in fig. 5 are both circular plate-shaped, and the structures 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.

In some embodiments, the driving assembly 150 may include a pneumatic mechanism, or a solenoid-operated mechanism, or other device capable of being operated by power supplied from a power source, and the disclosure is not limited thereto, and the driving assembly 150 may be operable to switch the distal end of each expandable member 140 between the collapsed state and the expanded state. The driving assembly 150 can also control the expanding or gathering degree of each expandable member 140 electrically or manually, is convenient to operate, and can adjust the expanding degree of the expandable members 140 according to actual conditions, thereby improving the flexibility of the optical head applying device 100.

The present disclosure improves the problem of low light transmission rate due to occlusion of hair by enabling the distal ends of the respective expandable members 140 to be inserted between the user's hair in a gathered state and the distal ends of the expandable members 140 to be spread out of the hair in an expanded state after insertion by the driving assembly 150 that enables the respective expandable members 140 to be gathered to each other or spread out from each other on the distal side of the optical member 120. In addition, the use effect of the transcranial light control device 200 using the head optical application device 100 can be improved, and the light emitted by the optical member 120 of the optical application device can be directly irradiated onto the scalp of the user and penetrate the skull, so that the brain function can be improved better. Similarly, the above configuration can also improve the measurement effect of the near-infrared device using the head optical application device 100, and achieve accurate and effective measurement results by plucking the hair between the head optical application device 100 and the scalp.

In some embodiments, head optical applicator 100 further comprises an actuator 160 coupled to drive assembly 150, wherein actuator 160 is configured to: translating actuation in a first, distal direction by actuation assembly 150 into deployment of each expandable member 140 and translating actuation in a second, proximal direction by actuation assembly 150 into gathering of each expandable member 140.

Specifically, the first direction is a direction toward the scalp, and the second direction is a direction away from the scalp. The transmission mechanism 160 can be disposed between the driving assembly 150 and each of the expandable members 140, the driving assembly 150 can drive the expandable members 140 to move by acting on the first base 110, or can directly drive each of the expandable members 140 to move by the transmission mechanism 160, wherein the transmission mechanism 160 can be connected to the first base 110, each of the expandable members 140, or can be in close contact with each of the expandable members 140, and the driving assembly 150, the transmission mechanism 160, the first base 110, and each of the expandable members 140 can be combined without conflict. The following description will be made in conjunction with specific structures adopted in various embodiments of the present disclosure, and details are not repeated herein.

In some embodiments, actuation in a first direction by the actuation assembly 150 is associated with the deployed state of each expandable member 140, and actuation in a second direction by the actuation assembly 150 is associated with the stowed state of each expandable member 140. The movement of the driving assembly 150 may also be associated with the movement of the optical member 120, further increasing the rate of irradiation to the scalp, thereby achieving better treatment or measurement results. For example, when the driving assembly 150 applies the driving in the first direction, the optical member 120 can be synchronously driven to move in the first direction, and when the driving assembly 150 applies the driving in the second direction, the optical member 120 can be synchronously driven to move in the second direction, so that when the optical member 120 moves in the direction close to the scalp, the distal ends of the expandable members 140 are expanded to pull out the hair between the optical member 120 and the scalp, and the distance between the optical member 120 and the scalp can be shortened, and the shielded hair can be pulled out at the same time, thereby achieving a better effect of receiving or emitting light.

In some embodiments, the transmission mechanism 160 may adopt a mechanical transmission manner, and specifically may include one or more transmission assemblies of a gear transmission assembly, a chain transmission assembly, and a link transmission assembly, and some embodiments below will describe the structure of the transmission mechanism 160 by taking the transmission mechanism 160 adopting a link transmission form as an example, but the disclosure is not limited thereto.

In some embodiments, the drive assembly 150 is further configured to drive the first base 110 to move in the first direction or the second direction. The drive mechanism 160 may be configured for operatively connecting the first base 110 with each expandable member 140 in the following manner: translating movement of the first base 110 in a first direction into unfolding of each expandable member 140 and translating movement of the first base 110 in a second direction into gathering of each expandable member 140.

In some embodiments, the first base 110 can be moved in a first direction or a second direction by the driving assembly 150, and the second base 130 is in a non-moving state, that is, the first base 110 can be moved relative to the second base 130 by the driving assembly 150. The first base 110 acts on the proximal end of each expandable member 140 through a drive mechanism 160 to switch between the deployed and stowed configurations.

The present disclosure provides various embodiments for the driving assembly 150 to drive the transmission mechanism 160 to move by driving the first base 110, and further switch each expandable member 140 between the expanded state and the gathered state, specifically including at least the following embodiments, wherein technical features in each embodiment may be combined with each other without conflict, so as to form other technical solutions capable of driving the transmission mechanism 160 to move by driving the first base 110.

Example one

As shown in fig. 1 to 8, the transmission mechanism 160 includes a connecting rod 161, and both ends of the connecting rod 161 are 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, so that the expandable member 140 will not bend laterally or inwardly during the expansion process, thereby ensuring a better hair-plucking effect. The second end of the connecting rod 161 is pivotally connected to the first base 110, so that the expandable member 140 can pivot along with the movement of the first base 110 via the connecting rod 161. The driving assembly 150 acts on the first base 110 to drive the first base 110 to move in the first direction or the second direction.

For example, as shown in fig. 1 to 4, the optical member 120 may be plural, the first base 110 has a rectangular plate shape, and the first base 110 has a first length direction along a long side thereof. The plurality of optical members 120 are sequentially disposed along the first longitudinal direction, and the plurality of expandable members 140 may be disposed at opposite sides of the optical members 120 in pairs along the first longitudinal direction. The number of the expandable members 140, the number of the optical members 120, and the arrangement manner are not particularly limited in the present disclosure, and the effects of emitting light or receiving light and opening hair can be achieved. In addition, the first base 110 may have an arc shape matching the arc shape of the head of the user, so as to facilitate the optical member 120 mounted thereon to further lean against the scalp.

In some embodiments, as shown in fig. 1 and 2, the expandable member 140 has an expansion body 143 and a first arc portion 144 disposed at a distal end of the expansion body 143, the expansion body 143 may be an arc plate, the number of the expandable members 140 shown in fig. 1 is two, and a plurality of expandable members 140 may be disposed along the first direction, and only one expandable member 140 is disposed on one side of the optical member 120 in the drawings for illustration, and the disclosure is not limited thereto. As shown in fig. 1, the shape of the expansion bodies 143 of the two expandable members 140 located on opposite sides of the optical component 120 are configured to expand outwardly from each other to facilitate the tendency of the two expandable members 140 to move toward a deployed state.

It can be understood that, as shown in fig. 1 and 2, the extension body 143 having an arc plate shape can press the opened hair during the spreading of each of the expandable members 140 to achieve a better hair-setting effect.

In some embodiments, a plurality of striking parts may be formed on the distal end of the extension body 143 in an outward extending manner, the plurality of striking parts are arranged along the first length direction, and the first arc-shaped parts 144 are respectively disposed at the distal ends of the striking parts, it is understood that the first arc-shaped parts 144 are parts contacting the scalp of the user, and are arc-shaped to improve the discomfort of the user when using the optical application device, and improve the wearing comfort. And the first arc-shaped part 144 can be made of flexible material, so that when the first arc-shaped part 144 contacts the scalp of the user and the expandable part 140 is expanded, excessive pressure cannot be applied to the scalp of the user, and pressure pain feeling is not generated.

In some embodiments, and with continued reference to fig. 1 and 2, the distal ends of the expandable members 140 are inwardly tapered to form stepped portions 147, the stepped portions 147 being located on opposite sides of the first arcuate portion 144, the first arcuate portion 144 abutting the scalp of the user when the apparatus to which the head optical applicator 100 is attached is worn, and the distal side of the stepped portions 147 is spaced from the scalp of the user to accommodate hair so as to compress the hair being plucked during expansion of each of the expandable members 140 for better hair plucking.

Illustratively, as shown in fig. 5 to 8, the optical member 120 may be one or more, and the first base 110 and the second base 130 are each in a circular plate shape, and when the optical member 120 is plural (as shown in fig. 5 and 6), one of the optical members 120 is disposed in the middle of the first base 110, and another plurality of optical members 120 are disposed around the optical member 120 located in the middle, and when the optical member 120 is one (as shown in fig. 7 and 8), the optical member 120 is disposed in the middle of the first base 110.

In some embodiments, with continued reference to fig. 5-8, a plurality of expandable members 140 are disposed around the one or more optical members 120, the number of expandable members 140 shown in fig. 5 and 7 being six for exemplary purposes only, and the present disclosure does not specifically limit the number of expandable members 140.

In some embodiments, as the user's head varies, it may occur that the distal end of the expandable member 140 may not rest entirely against the scalp during expansion of the expandable member 140. Therefore, the comb teeth 142 (as shown in fig. 5 and 6) may be disposed at intervals on the outer side surface of each expandable member 140, and the comb teeth 142 may further spread the spread hair in the spreading direction when the expandable member 140 is expanded outward, thereby preventing the spread hair from approaching the region between the optical member 120 and the scalp, and achieving a better hair spreading effect. The comb teeth 142 may have various shapes such as a spherical shape and a rectangular parallelepiped shape, and is not particularly limited herein.

In some embodiments, the cross-sectional area of the expandable member 140 gradually decreases from its proximal side to its distal side, and particularly in conjunction with fig. 5-8, the expandable member 140 may be in the shape of an arc plate, a triangle plate, or other shapes, such that the cross-sectional area of the expandable member 140 gradually decreases from its proximal side to its distal side, such that the proximal end of the expandable member 140 can be stably pivoted to the second base 130 and the transmission mechanism 160, and the insertion of the distal end of the expandable member 140 into the hair of the user is facilitated.

In some embodiments, as shown in fig. 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 seats 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.

In some embodiments, the base plate 131 may be integrally formed with or detachably connected to the first mounting seat 132, and when the base plate 131 is detachably connected to the first mounting seat 132, the number of the expandable members 140 pivotally connected to the first mounting seat 132 and the first mounting seat 132 may be adaptively adjusted according to the amount of hair of the user, that is, in the case of a large amount of hair of the user, the number of the first mounting seat 132 and the expandable members 140 may be increased, and in the case of a small amount of hair of the user, the number of the first mounting seat 132 and the expandable members 140 may be decreased.
