Detailed Description

The structure of the present system and the functions performed are described in detail below with reference to the accompanying drawings.

The tooth polishing equipment comprises a detection part, a polishing part and a control part, wherein the detection part is used for detecting the individual condition of a patient, and the control part is used for controlling the polishing part to operate according to the detected individual condition; wherein the content of the first and second substances,

the detection section includes:

the infrared thermometer 11 is arranged in the stick body in a manner of being tightly attached to the stick body and is used for measuring the working temperature of the grinding part and the oral temperature of a patient;

an image sensor 12 provided inside the bar body in close contact with the upper portion of the bar body, for capturing a tooth image;

the portion of polishing includes:

a polishing surface 21, the surface of which is provided with a plurality of holes which are equal in size and are orderly arranged;

the protrusion 22 is used for polishing teeth and can perform telescopic movement through the rectangular hole on the surface of the polishing disc 21; the structure comprises a first bulge 221 and a second bulge 222, wherein the first bulge 221 and the second bulge 222 are sequentially distributed in a cuboid shape, the first bulge 221 is a small cuboid formed by pressing quartz particles, and the second bulge 222 is a small cuboid formed by pressing chromium-zirconium-copper particles;

the air bag 23 is a cavity arranged inside the polishing surface 21 and comprises a first air bag 231 and a second air bag 232, and the first air bag 231 and the second air bag 232 respectively control the first protrusion 221 and the second protrusion 222 to stretch and retract;

an automatic inflator 24 inside the stick body for inflating and inhaling the air bag 23;

the control section is configured to:

judging the damage degree of the enamel according to the tooth gray value detected by the image sensor 12; when the gray value of the tooth is detected to be out of the normal value range, the damage degree of the enamel of the patient is large, the hardness of the tooth is small, the tooth is easy to polish, and the polishing surface 21 is used for polishing the tooth; when the gray value of the tooth is detected to be within the normal range, the damage degree of enamel is small, the hardness of the tooth is high, and the tooth is not easy to polish, at the moment, the first bulge 221 is selected to polish the tooth, namely, the inflator pump 24 is started to inflate the second air bag 231, so that the first bulge 221 extends out of the polishing surface 21, and the tooth is polished by the first bulge 221;

above-mentioned ordinary process of polishing can make the grinding pin temperature rise, when detecting that the operating temperature of first arch 221 exceeds oral cavity temperature, higher temperature makes patient's heat-sensitive reaction take place easily, the abrasive material can take place the thermal decay simultaneously, reduce the effect of polishing, then control is opened pump 24 and is aerifyd No. two gasbag 232, make the protruding 222 of wear-resisting chromium zirconium copper second of lower half stretch out the face of polishing 21, because chromium zirconium copper's material characteristic, the protruding 222 of second can in time dispel the heat when polishing the tooth, avoid taking place heat-sensitive reaction, keep the effect of polishing, reduce the abrasive material heat waste.
