Automatic water seal type suction device for dental unit chair

Abstract

The present invention relates to an automatic wet suction apparatus for a dental unit chair. The automatic wet suction apparatus for a dental unit chair includes: a water-sealed vacuum pump having a sealing water inlet, an air inlet, and an outlet through which a fluid sucked through the sealing water and air inlets is discharged; a cyclone centrifugation means having an upper end connected to theair inlet of the water-sealed vacuum pump, having an upper end portion circumference connected to a suction tip of the unit chair, separating air and foreign matter-containing dirty water sucked froma patients oral cavity, and removing the separated dirty water; and a sealing water recirculation unit provided with a sealing water tank having a lower end connected to the sealing water inlet of the water-sealed vacuum pump, having an upper end portion circumference connected to the outlet of the water-sealed vacuum pump, and having a discharge port at the upper end thereof, a cooling means cooling sealing water supplied from the sealing water tank to the water-sealed vacuum pump, and a sealing water quantitative supply pump supplying a predetermined amount of the sealing water in the sealing water tank at a time to the water-sealed vacuum pump.

Description

【Technical field】 [0001] The invention relates to a water-sealed suction device, which provides a vacuum for dental treatment and a comprehensive dental treatment chair used in surgery, so as to suck out sewage mixed with saliva and blood concentration from the oral cavity of a patient. More specifically, the foreign matter is completely separated from the sucked saliva, blood concentration and other sewage to prevent the vacuum pump from being damaged and the suction efficiency caused by the inflow of debris into the vacuum pump. Reduce the amount of sealing water. The device is an automatic water-sealed suction device used in a dental comprehensive treatment chair. The device can completely separate foreign bodies such as saliva and blood concentration from the air and then concentrate and discharge them. It can also be discharged through a low-cost and efficient sterilization device. The foreign matter is sterilized to achieve the effect of preventing environmental polluti...

AI Technical Summary

Problems solved by technology

During dental treatment, the excessive water consumption is completely suppressed through the circulation device, and the saliva, thick blood and other sewage sucked from the patient's mouth are completely separated from the air, and only clean air flows into the water-sealed vacuum pump, which can effectively prevent foreign matter Contamination of sealing water, thereby reducing the problem of damage and inefficiency of the vacuum pump due to the incorporation of foreign matter, which is the main purpose of the present invention
