▎ 摘　　要

NOVELTY - The mirror has a detecting unit detachably connected with a control unit. The control unit is detachably fixed with an energy supply unit, where the detecting unit is provided with a glass lens (1). The glass lens is fixed on a lens base of a glasses frame (5). A waterproof layer (2) is padded between the glass lens and the lens base. An interlayer is provided between the waterproof layer and lens base for maintaining constant temperature. A graphene circuit board (4) is provided on the interlayer. A phase change heat storage substance (3) is filled on the periphery of the graphene circuit board. A front end of the ratchet wheel guide sheet is connected with the spring pawl through the rotation of the one-way rotating switch. The battery box that is connected with handle connecting piece through rotary clamping socket. USE - The detachable graphene-constant -temperature fog removing mouth mirror is useful for dental treatment in medical appliances. ADVANTAGE - The mirror uses an easy-to-operate one-way rotary switch to perform controllable heating and defogging of the mouth mirror lens, and the detachable design is convenient for disinfection, recycling and reuse, which reaches the purpose of convenient and safe heating and de-defogging. The mirror realizes the temperature-controllable mouth mirror heating fog-proof, improves the lens fogging phenomenon through the phase change constant temperature material interlayer, prolongs the temperature duration, limits the heating amplitude, avoids the danger of scalding the patient, so as to ensure the safety of the inspection operation, and realizes the effect of repeatable use. The chargeable handle and the lens design is capable of being used for disinfecting and recycling are designed to protect the mirror device more environment-friendly. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing a hierarchical structure of the detection lens of the detachable graphene-constant -temperature fog removing mouth mirror. 1Glass lens 2Waterproof layer 3Phase change heat storage substance 4Graphene circuit board 5Glasses frame
