Abstract

Disclosed therein is a sterilizer for dental contaminants, which can prevent contamination occurring by the surface or a discharge hole of a cuspidor and a discharge hole of a suction mounted on a side of a dental unit chair used to spit out contaminants, such as blood or pus, remaining in a patient'"'"'s mouth during a dental treatment. The sterilizer includes: a lid having a size as large as to cover an entrance portion of the cuspidor; an ultraviolet lamp mounted on the inner surface of the bottom of the lid; an opening and closing means connected to the lid for opening and closing the lid; and a control part for opening and closing the lid through the opening and closing means and controlling the turning on and off of the ultraviolet lamp. Additionally, in another aspect, the sterilizer may include: a body part for storing contaminants therein; an inlet part connected to a discharge hole of the cuspidor or a suction for transferring the contaminants to the body part; an outlet part connected to a drain pipe for discharging the contaminants stored in the body part to the drain pipe; and a ultraviolet lamp mounted inside the body part and having a light-emitting portion.

Claims

1. A sterilizer for dental contaminants for sterilizing a cuspidor fixedly mounted to a dental unit chair, comprising:

a lid having a size as large as to cover an entrance portion of the cuspidor;

an ultraviolet lamp mounted on the inner surface of the bottom of the lid;

an opening and closing means mounted on the outer surface of the cuspidor fixedly mounted to the dental unit chair and connected to the lid for opening and closing the lid; and

a control part for opening and closing the lid through the opening and closing means and controlling the turning on and off of the ultraviolet lamp.

2. The sterilizer for dental contaminants according to claim 1, wherein the lid is opened and closed by an operational rod connected to an operating mechanism mounted inside the opening and closing means.

3. The sterilizer for dental contaminants according to claim 1, wherein the opening and closing means includes:

a guide rod connected integrally with the lid and having a guide groove or a guide protrusion for allowing rising and rotation of the lid;

a guide member having a guide protrusion or a guide groove coupled with the guide groove or the guide protrusion; and

the operating mechanism for operating the guide rod.

4. A sterilizer for dental contaminants comprising:

a body part for storing contaminants therein;

an inlet part connected to a discharge hole of the cuspidor or a suction for transferring the contaminants to the body part;

an outlet part connected to a drain pipe for discharging the contaminants stored in the body part to the drain pipe; and

a ultraviolet lamp mounted inside the body part and having a light-emitting portion.

5. The sterilizer for dental contaminants according to claim 4, further comprising a stirrer having stirring wing for stirring the contaminants stored in the body part and a driving portion for rotating the stirring wing.

6. The sterilizer for dental contaminants according to claim 5, further comprising a foreign substance-removing part mounted on the lower end of the body part and tightly sealed with an openable lid.

7. The sterilizer for dental contaminants according to claim 4, further comprising a foreign substance-removing part mounted on the lower end of the body part and tightly sealed with an openable lid.
