Description

Technical Field

[0001] The utility model relates to the technical field of oral self-viewing mirrors, in particular to an oral self-viewing mirror. Background Art

[0002] In daily life, when people brush their teeth, they often pay attention to brushing the part they can see. The inside and outside of the teeth in the mouth, especially the inside and back of the big teeth, are not brushed carefully because they cannot be seen. Over time, dental plaque or calculus, tooth decay, etc. will be generated. It is not only unsightly but also produces odor. When the symptoms of tooth decay are mild, they are generally invisible and unfeeling. When they can be felt, tooth decay is already quite serious, which seriously affects oral hygiene. Therefore, it is very necessary to study an electronic oral camera that can be used in daily life and can be self-checked, so that people can check their oral hygiene regularly, so that they can deal with problems as soon as possible and effectively prevent oral problems.

[0003] For example, a self-examination electronic oral mirror provided in the Chinese patent application with application number 201620550693.6 includes a mirror barrel and a mirror rod. The mirror barrel and the mirror rod are connected by a connecting mechanism. A reflective lens is fixedly provided on the top of the mirror rod. The reflective lens is arranged at a 45-degree angle to the mirror rod. A camera and an LED light-emitting diode arranged around the camera are arranged on the top of the mirror barrel. A dry battery and a video conversion module are arranged in the lens barrel. The technical solution has a novel structure and a reasonable design. The camera, reflective lens and video conversion module are arranged to facilitate people to self-examine their oral conditions in daily life, thereby effectively preventing the deterioration of oral diseases. The connection mechanism is arranged to realize the detachable connection of the mirror rod, which is convenient for replacement and avoids cross infection of the reflective lens. The mirror with this structure is highly practical and easy to promote and apply.

[0004] However, the following problems still exist in this technical solution: in this technical solution, the mirror rod is fixed by a retaining spring, and the device needs to use force to remove the mirror rod from the retaining spring. The retaining spring is easy to break after long-term back and forth fixation, resulting in the inability to fix the mirror rod. Utility Model Content
