Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, specifically to a swing-type dental light curing machine lamp head. Background Technology

[0002] A dental light-curing machine is an oral device used to repair teeth. It uses the principle of light curing to rapidly cure dental repair resin materials under the action of light waves within a specific wavelength range, thereby filling cavities or bonding brackets.

[0003] During dental treatment, most patients lie flat or recline on the dental chair. During the treatment, the dentist will insert the lamp head of the light curing machine into the patient's mouth. In practice, the angle of the light beam needs to be adjusted as needed for different patients and teeth in different positions. This is to facilitate better treatment and increase the dentist's operating comfort, thereby keeping the treatment process in a better state.

[0004] Existing UV curing machines generally have two implementation methods for the lamp head. One method is that the UV curing machine handle is straight, and the lamp head is at a 90° angle or other angles, but the angle is always fixed. The other method is that the lamp head and handle have a swing structure, but the structure is relatively complex, the manufacturing cost is high, and it is not convenient to adjust and maintain. Utility Model Content

[0005] The purpose of this invention is to provide a swing-type dental light curing machine lamp head that is low in manufacturing cost, easy to maintain, and can be manually adjusted in terms of swing angle without the need for other tools during use.
