As shown in FIG. 3, the shooting component 4 of the present invention includes a guide column 41, a lifting component 43, a shooting component 44 and a electrical component 45. Guide column 41 and the electrical component 45 can be fixed on the bottom of the box directly or indirectly, preferably, on the upper surface of the circuit board box 11 at the bottom of the tank. The materials of the tank can be metal or non-metallic, so that the guide column 41 and electrical component 45 can be directly welded or fixed by screw. Shooting component 44 fixed in the lifting component 43, and the lifting component 43 mounted on guide column 41. Electrical component 45 is positioned below the lifting component 43 to raise or descend the lifting component 43.

As shown in FIG. 5, the electrical component 45 includes a motor 451 and a screw 452 which is connected with the motor 451, the top of screw 452 screws into the threaded hole in the bottom of the lifting component 43 (as shown in FIG. 6), and the motor 451 is fixed on the circuit board box by the motor seat 452. The motor 451 is used to control screw 452 clockwise or counterclockwise rotation, then drive the lifting component 43 up or down along the guide column 41 to meet the height adjustment of the camera while shooting the face and the tongue.

As shown in FIG. 4, more than 2 angle guide pieces 42 are fixed on the guide column 41 (there are four in the figure), the angle guide piece 42 which is located in the up side with the inclined plane 421 to guide the camera to tilt forward while raising, the angle guide piece 42 which is located in the lower with the vertically plane 422 to guide the camera to lift steadily. When the electrical component 45 leads the lifting component 43 to rise, the camera raising steadily with the vertical guide plane 422, while the camera has a lens which can protract, whose center of gravity is toward the front, so under the guidance of the inclined plane 421 with the angle of guide piece 42 the camera can tilt forward, the angle of the tilted camera is identical with the angle of the inclined plane 421, and the angle ranges between 10° and 30°.

Preferably, guide columns 41 are a pair of slotted metal rods 411 facing against each other with slot, their respective opposite sides of the metal rod contain the longitudinal extension of the slot, the slot may partly extend the metal rod or extend the both ends of the metal rod, a slider 412 is positioned on the metal rod 411, the slider 412 can slide in the slot, the slider 412 permanently connect to the connecting part of two laterals 432 of lifting component 43 (as shown in FIG. 6), which can be riveted or screw fixation, so that the lifting component 43 and the shooting component 44 can slide on the guide column 41.

Further, as shown in FIG. 6, the connecting part of two laterals 432 outside the lifting component fix with the slider 412, both of the medial sides of the lifting component contain flake-like parts of semicircular arc 431, and the flake-like parts are fixed by welding. As shown in FIG. 7, the shooting component 44 includes a camera 441 and a camera container 442, the two laterals of the camera container 442 carries a pair of rotatable bearings 443, the pair of the bearings 443 are set on the flake-like parts 431 assemble on the inner side of the lifting component 43, the camera container 442 can rotate an angle in the lifting component 43.

The steps of the invention of the device for collecting information from face and tongue includes two steps: collect the face information and the tongue information. When shooting the face, the camera's lens plane perpendicular to the face and collect the information from the face; when shooting the tongue, tilt forward while raising the camera position to the vertical plane with the tongue, and collect the further information from tongue. Switching process in details are as follows:

When needs to switch from shooting the face to shoot the tongue, the screw 452 of the electrical component 45 rotates clockwise, so that the shooting component 44 can be raised, and the shooting component 44 moves upward along the angle guide pieces 42 of the vertical guide plane 442, since the weight of the front lens of the camera, the center of gravity is out of the lifting component, the component have taken the trend of outward tilting. When the shooting component 44 rises further, the weight of the camera forces the rotating bearing 443 to rotate, it turns outward and against the angle guide piece 42 which on the upside of the metal rod 411 of the inclined plane 421, so when the camera tilts, the angle is as same as the angle of the inclined plane 421, and the angle ranges between 10°-30°. In this way, the switch from shooting the face to shoot the tongue can be achieved.

Preferably, when the camera's position changes from perpendicular to the face to perpendicular to the tongue, little change of distance between the lens and the film surface occurred, the present invention provides a mechanical structure that can automatically rotate the camera's lens to focus. As shown in FIG. 8, the shooting component 44 of the invention also contains an angle rotary handle 47, one end of the angle rotary handle 47 surrounds the camera lens 441 and can rotate the lens and the other end of the angle rotary handle 47 fixed on the tank 1 or adopt the fixation which can keep the angle rotary handle 47 and the tank 1 relatively static, so that when the camera rises, one end of the angle rotary handle 47 fixed, the other end can rotate the lens to achieve to focus tongue shot, when the camera descends, it can be reversed to the original location. Since the structural features of different cameras, the angle required to change respectively while adjusting the focal length, the optimal angle range is 0°-40°.

We can pre-set up the relation between the raising distance of the shooting component and the angle of the lens which controlled by the angle rotating handle, so that when the camera lens rotates down at any angle, the lens focal length can be sure to focus.

Similarly, when needs to switch from shooting the tongue to shoot the face, the screw 452 of the electrical component 45 rotates counter-clockwise, consequently the shooting component 44 descends and the shooting component 44 moves downward the vertical guide plane 442 along the angle guide pieces 42. This process is reverse to the raise process, and the angle ranges between 10°-30°. In this way, the switch from shooting the tongue to shoot the face can be achieved.

According to the preferred embodiment, a device for collecting information from face and tongue which is absence in the existing technology can be provided, which is able to achieve the information collection from the patient's tongue and face at one-time. It is beneficial to integrated analysis and comprehensive judge for the patients' focus.
