Description

TECHNICAL FIELD The present disclosure relates to a technical field of transcranial light regulation method and equipment, especially relates to a hair parting assembly, also said light guide device for transcranial light, and an apparatus for transcranial light regulation. BACKGROUND Research has shown that red light or near-infrared light with a certain wavelength can penetrate the human skull and produce beneficial effects on cells by stimulating them, thereby achieving the goal of treating cerebral diseases, such as neurodegenerative diseases, psychiatric disorders, traumatic disorders, etc. In the existing transcranial light regulation products, the optical assembly and the hair parting assembly are correspondingly provided and fixedly assembled together, it mainly provides corresponding light guide pillars on the optical assembly to interpose between the hairs, or part the hairs ("part the hairs" means to poke into and push the hairs aside in disclosure) by a drive assembly driving the correspondingly provided hair parting member from a gathered state to a deployed state, thereby achieving light guide effect (also referred to as a light guide assembly or a light guide device for transcranial light). It is difficult for the former to directly contact the root of the hair to transmit the transcranial light to the scalp, while the latter can only partially part the hair at the corresponding position of the optical assembly, degrading the transmission effect of the transcranial light, which in turn degrades the treatment effect of the transcranial light. Besides, the above two hair parting methods both depend on complicated mechanical structure and have high cost. WO2021/068278A1 disclosed a light-emitting device, apparatus and system for transcranial light modulation. The device comprises: a light source portion; a light-transmitting layer, with the light-transmitting layer being arranged on an emergent side of the light source portion; and a light guide member, with the light guide member having one end fixed to the side of the light-transmitting layer that is opposite the light source portion, and being configured to guide light that is transmitted from the light-transmitting layer. By means of providing the light guide member on the light-emitting device for transcranial light modulation, the light guide member passes between the hair of a user and comes into direct contact with the scalp of the user so as to reduce the influence of hair shading on the light transmission efficiency, and the light emitted by the light source portion can be directly guided to the scalp of the user by means of the light guide member, so as to improve the irradiation effect of the light-emitting device. However, the light source portion and the light guide member are correspondingly provided and fixed assembled together, and corresponding light guide pillars are provided on the light source portion to interpose between the hairs, which makes it difficult to directly contact the root of the hair to transmit the transcranial light to the scalp. SUMMARY The invention relates to a device as defined in the appended claims. Embodiments, examples or aspects in the following disclosure which do not fall under the scope of the claims are presented for illustration purposes only and do not form part of the invention. In response to the aforementioned technical issues in the prior art, the present invention, which is identified in the appended set of claims, provides a hair parting assembly (also referred to as a light guide device for transcranial light) and a transcranial light regulation apparatus, which can part and push the hair on the user's scalp aside by means of the hair-entering member to form an optical path, thereby transmitting transcranial light to the scalp. By means of the hair parting assembly, a hair parting device, and a transcranial light regulation apparatus , the light transmission rate is high, the structure is simple, and the cost is lower. According to the first aspect of the present disclosure, a hair parting assembly is provided as in claim 1. It comprises a first bridging portion and at least one first hair-entering member for transmitting transcranial light. The first bridging portion at least partially extends in a circumferential direction in a strip-shape or a band-shape. Each first hair-entering member includes a hair-entering portion and a maintaining portion, both of which are permeable to the transcranial light and is provided traverse to the first bridging portion, such that a lengthwise direction of each first hair-entering member is traverse to extension direction of the first bridging portion, and spaces are provided on both sides of each first hair-entering member in the extension direction of the first bridging portion. The first bridging portion is configured to travel along the scalp of a user, the first hair-entering member is configured to part the hairs as the first bridging portion tra
