[0039] Since the first opening and the second opening of this embodiment are opened in opposite directions, the buzzer 7 emits a prompt sound after the teeth whiteness is determined, which can better inform the user of the teeth whiteness detection process. This embodiment uses a gun-shaped handheld device as the shape of a portable shell of the teeth whiteness detection device. The ergonomic grip design can better enhance the user experience and is also convenient for beauty practitioners to perform teeth whiteness detection on the users to be tested, making it more suitable for use by beauty service agencies.

[0040] It should be noted that the gun-shaped portable shell is only a specific solution of this embodiment. After reasonable deduction and transformation by technical personnel in this field, the portable shell can also be integrated into the shell of wearable devices such as AR glasses or mobile terminals.

[0041] Third embodiment:

[0042] As an improvement over the above-mentioned first and second embodiments, in order to improve the acquisition quality of the user's tooth pictures to be tested, the camera teeth whiteness detection device of this embodiment also includes a lens module, which includes a cylindrical LED shell arranged at the first opening, a lens unit located in the cylindrical shell, and a polarized lens located outside the lens unit.

[0043] On the one hand, the lens unit can facilitate magnification of the target tooth at the lens module. As a preferred solution but not a limitation, the lens unit can also include a filter coating for filtering the messy light of the target tooth. The polarized lens is conducive to shielding the side light, reducing the interference of the side light to further improve the acquisition quality of the image of the tooth to be tested.
