Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to the attached drawings, the automatic suction device comprises a shell 1, a charging plug 13 and a main switch 14 are installed on the surface of the shell 1, a screw rod 5 penetrates through the center of the shell 1, a screw cap 4 is installed at the upper end of the screw rod 5, bearings 3 are symmetrically installed at the upper part and the lower part of the screw cap 4 in an interference pressing mode respectively, the bearings 3 are embedded into an upper counter bore and a lower counter bore of the shell 1, a driven wheel 6 is installed in the middle of the screw cap 4 in a spline connection mode, a driving wheel 7 is connected to one side of the driven wheel 6 in a gear meshing mode, a power output shaft of a motor 8 is connected to the lower part of the driving wheel 7 in a spline connection mode, the motor 8 is fixedly installed on the inner surface of the shell 1, a battery pack 2 is arranged below the other side of the driven wheel 6, the battery pack 2 is arranged in a groove in the inner surface of, the lower part of the shell 1 is connected with a suction tube 10 in a positioning boss and groove matching mode, the lower half part of the screw rod 5 is arranged in the center of the suction tube 10, the bottom of the screw rod 5 extends into the suction tube 10 and is embedded with a piston 11, and a plurality of needle tubes 12 are arranged below the suction tube 10.

The utility model can be divided into a syringe system and an electric suction system from the practical use angle, and the syringe system is a disposable consumable material; electric suction systems are reusable devices. The syringe system comprises a suction cylinder 10, a piston 11 and a syringe needle 12, and in order to ensure cleanness and sanitation and prevent cross infection, the system is scrapped after one-time suction treatment of a patient is finished; the electric suction system comprises a shell 1, a battery pack 2, a bearing 3 (2 in the upper and lower directions), a screw cap 4, a screw rod 5, a driven wheel 6, a driving wheel 7, a motor 8, a limit switch 9, a charging plug 13 and a main switch 14, and the electric suction system can be repeatedly used and maintained.
