Abstract

The electrothermally defogging oral reflector consists of one reflector and one handle. The handle has one pedestal set in the front end for the reflector to be set on, and there are one electrothermal element fixed in the pedestal, one battery compartment set inside the handle, and one switch connected to the electrothermal element. The handle axis and the mirror of the reflector are in one angle of 110-160 deg. The electrothermal element constituted of spiral resistive wire in the bottom of the pedestal heats the reflector to temperature higher than that of air inside oral cavity, so as to avoid vapor condensation in the mirror and to maintain clear mirror. The present invention has simple structure and convenient use.

Description

Technical field: [0001] The invention relates to medical equipment, in particular to a medical auxiliary observation device, in particular to a dental reflector, in particular to an electrothermal defogging oral reflector. Background technique: [0002] In the prior art, a dentist oral mirror is composed of a reflector and a handle, the reflector is arranged at the front end of the handle, and the mirror surface of the reflector forms an angle between 110° and 160° with the handle. When in use, the reflector extends into the patient's mouth, and the dentist adjusts the angle of the reflector to reflect the lighting on the treatment chair to the teeth that need to be inspected and treated, and then observe. Due to the high humidity of the gas in the oral cavity, the temperature is usually higher than the room temperature, and the mirror surface of the mirror is usually equal to the room temperature. Therefore, the water vapor in the oral cavity is easy to condense on the mirr...
