Freezing point hair removal instrument with disinfection function

The invention discloses a freezing point hair removal instrument with a disinfection function, which comprises a hair removal instrument body internally provided with a working cavity, a pulse light-emitting component arranged in the working cavity, and a light-transmitting part mounted on the hair removal instrument body and blocked at one end, with an opening, of the working cavity, and the light-transmitting part is provided with a light outlet for emitting pulse light outwards; the surface of the light-transmitting piece and the light outlet are coated with photocatalyst coatings. And a reflecting cover covering the outer side of the light-transmitting part is detachably mounted on the hair removal instrument body. Before and after an unhairing operation, the reflecting cover is mounted, pulsed light emitted from the light outlet is reflected by the reflecting cover and then is emitted to the light-transmitting piece coated with the photocatalyst coating, a photocatalyst generates substances with strong o
