Automatic dry suction device for dental unit chair

Abstract

According to the present invention, disclosed is a full automatic dry-type suctioning device for a dental unit chair. The full automatic dry-type suctioning device of the present invention comprises:an air compressor having an air suctioning port and a discharging port; and a cyclone centrifuging means having a top end connected with the air suctioning port of the air compressor, having a top endcircumference connected with a suctioning tip of a unit chair, and separating and removing waste water including foreign materials suctioned from the oral cavity of a patient from air. The cyclone centrifuging means comprises: a cyclone gas and liquid separator having a top end connected with the air suctioning port of the air compressor, having a top end circumference connected with the suctioning tip of the unit chair, and having a bottom end having a cone unit disposed thereon to have a foreign material discharging port; a foreign material storage having a feeding port disposed at the topend thereof to be connected with the foreign material discharging port of the cyclone gas and liquid separator, and having a discharging port disposed at the bottom end thereof; a branch pipe having both ends respectively connected to the foreign material discharging port of the cyclone gas and liquid separator and the discharging port of the foreign material storage through a three way valve; andan exhaust pipe for connecting the branch pipe and the discharging port of the air compressor. The consumption of water can be completely prevented. Also, foreign materials automatically separated are exhausted without stopping the machine.

Description

technical field [0001] The invention relates to a suction device, which applies vacuum to a dental comprehensive treatment chair used in dental treatment and operation, so as to suck out sewage mixed with saliva and thick blood from the patient's oral cavity. The present invention relates to an automatic dry suction device for a comprehensive dental treatment chair. In more detail, it uses the suction force of an air compressor to provide a vacuum for the comprehensive treatment chair, which can not only completely suppress the conventional wet (water seal suction) Type) The excessive water consumption of the vacuum pump can also completely separate the foreign matter from the inhaled sewage containing saliva, blood concentration, etc., exactly preventing the foreign matter from flowing into the vacuum pump, thereby preventing the vacuum pump from being damaged and the problem of low efficiency. Background technique [0002] Generally, a dental unit chair used in a dental of...
