When the miniature camera shoots, the vertical distance between the lens and the tongue body is changed according to the prompt of the buzzer in the ultrasonic ranging module, and when the buzzer stops sounding, the preset distance is met, shooting of the tongue picture is completed, and fixation of shooting distance is realized.

The switch of the ultrasonic ranging module and the LED auxiliary light source is positioned at the bottom of the shell.

The LED auxiliary light source is a cold light modulation source, and the influence of external environment light on tongue images is avoided.

The tongue picture shot by the miniature camera is transmitted to a display in a wired or wireless mode.

The shell is used for assembling the miniature camera, the LED auxiliary light source and the ultrasonic ranging module into a shooting device. During detection, the ultrasonic ranging module and the LED auxiliary light source are turned on, the LED auxiliary light source is started and irradiates on the tongue surface, and finally tongue image shooting is carried out in the set measuring range of the ultrasonic ranging module.

The miniature camera has the functions of automatically zooming and clearly shooting tongue images. The tongue picture is projected onto the surface of the image sensor through the optical image generated by the lens, then converted into an electric signal, converted into a digital image signal after A/D conversion, and transmitted to the display for clearly displaying the tongue picture.

The utility model has the advantages that:

the utility model can shoot tongue images at a constant distance, and has small volume, portability and simple operation;

the ultrasonic ranging module is adopted, so that the ultrasonic wave has the advantages of easy directional emission, good directivity, easy control of strength and no need of direct contact with an object to be measured; under the condition of meeting the requirement of reducing the volume of the tongue diagnostic instrument, the shooting distance of the tongue picture is controlled by ultrasonic signals in a wireless way, so that the tongue picture is more in accordance with the unified specification;

the utility model adopts a cold tone LED auxiliary light source.
