The hole wall of the first through hole 11 may also be provided with a reflective layer 15, so that light returning from the object to be detected is transmitted to the camera 81 of the electronic device 8, the possibility that the light escapes from the hole wall of the first through hole 11 through the first through hole 11 is reduced, and the accuracy of the detection result is improved.

In one possible embodiment, the cavity 14 is provided with a light-conducting material.

In a possible embodiment, the detection device further comprises a polarization assembly 2, the polarization assembly 2 is mounted to the electronic device 8, and at least part of the polarization assembly 2 can be located between the camera 81 and the object to be detected.

Because of the different degrees of reflection and scattering of incident light by the skin at different depths, the reflection of the superficial skin does not generally change the polarization direction of light, whereas the dermis and subcutaneous tissue change the polarization direction of light. When the polarization direction of the first polarization member 21 and the polarization direction of the second polarization member 22 are parallel to each other, the polarization direction of the light reflected from the superficial skin is not changed by the skin, and therefore, the part of the light can pass through the second polarization member 22, and the light reflected from the dermis and the subcutaneous tissue is scattered, so that the polarization direction of the incident light is randomly changed, therefore, only the part of the light which is still the same as the polarization direction of the incident light after scattering can pass through the second polarization member 22, and the rest of the light cannot pass through the second polarization member 22 and is filtered by the second polarization member 22, so that the light reflected by the dermis and the subcutaneous tissue is attenuated in the light received by the camera 81, and the contrast of the light directly reflected by the epidermis is enhanced, and the image photographed in this state can be analyzed, and the stratum corneum, pore structure, skin layer structure, skin, Skin smoothness, fine lines on the skin surface, etc.

When the polarization direction of the first polarization member 21 and the polarization direction of the second polarization member 22 are perpendicular to each other, the polarization direction of the light reflected from the superficial skin is maintained as the polarization direction of the original incident light, and thus, the light cannot pass through the second polarization member 22, but the polarization direction of the light reflected from the dermis and the subcutaneous tissue is randomly changed due to the scattering effect, so that at least part of the light reflected from the dermis and the subcutaneous tissue can pass through the second polarization member 22, and the second polarization member 22 is used for filtering the light reflected from the superficial skin, and therefore, the camera 81 can receive only the light reflected from the dermis of the skin, analyze the image photographed in this state, and can obtain the skin pigmentation, the pimple, the blood vessel, and the like.

Through the design, the user can acquire corresponding skin information, so that the user can know the skin condition of the user more conveniently, and skin care products more suitable for the user can be selected.

In one possible embodiment, the first polarization member 21 can rotate relative to the second polarization member 22, so that the polarization direction of the first polarization member 21 and the polarization direction of the second polarization member 22 can be switched between vertical and parallel, thereby facilitating the user to know the skin condition of the user more comprehensively.

In one possible embodiment, as shown in fig. 6, the first through hole 11 comprises at least a first hole section 111 and a second hole section 112, wherein the second polarizing member 22 is capable of extending into the first hole section 111, and the enlarging member 7 is located between the second hole section 112, the second polarizing member 22 and the camera 81. Specifically, the diameter of the first hole section 111 is larger than that of the second hole section 112, and the light-transmitting structure 13 is disposed along the circumferential direction of the second hole section 112 and is communicated with the first hole section 111.

By this arrangement, the polarizing assembly 2 can be positioned between the camera 81 and the object to be detected, or can be positioned away from between the camera 81 and the object to be detected. So that the camera 81 can capture an unpolarized image.

When the detection device is in a normal detection mode, i.e. the polarizing component 2 is not positioned between the camera 81 and the object to be detected, the images taken in this state can be used to analyze skin deep wrinkles, pores, etc.; when the detection device is in the polarization detection mode, and the polarizing component 2 is positioned between the camera 81 and the object to be detected, the image shot in the state can be used for analyzing skin pigmentation and the like, and the detection device can have two states of a common detection mode and a polarization detection mode through the design, so that the function of the object to be detected is richer, and the actual use requirement is more met.
