the first step: the automatic sample feeding device is powered by a connecting wire (7), and after the device is started, a rotating motor (17) and a star-shaped motor (18) drive a first rotating disc (2) and a second rotating disc (3) to rotate;
and a second step of: placing the breath card sample into a sample groove (4) on the second turntable (3), arranging a pull bolt assembly (13) below each sample groove (4), and stopping the breath card sample in the sample groove (4) through the pull bolt assembly (13), wherein the sample groove (4) sequentially passes through the position of the sensor (23) along with the rotation of the first turntable (2) and the second turntable (3);
and a third step of: a plurality of positioning holes (6) are formed in the edge of the first rotating disc (2), and the positioning holes (6) are in one-to-one correspondence with the sample grooves (4); a square groove is formed in one side of the mounting bottom plate (1), an electromagnet (10) is arranged in the square groove, a photoelectric sensor assembly (8) is arranged on one side of the electromagnet (10), a first sensing head (803) and a second sensing head (804) in the photoelectric sensor assembly (8) correspond to each other, a positioning hole (6) passes through the space between the first sensing head (803) and the second sensing head (804) along with the rotation of the first rotating plate (2), when the positioning hole (6) is positioned between the first sensing head (803) and the second sensing head (804), the electromagnet (10) is electrified, so that the electromagnet (10) has magnetism, a circular head (135) is driven to move towards the electromagnet (10), and a blocking rod (131) is further moved away from the lower part of the sample groove (4);
fourth step: when the baffle rod (131) is removed from the lower part of the sample groove (4), the expiration card sample falls into the detection bin from the outlet opening (21), and when the expiration card sample is positioned at the outlet opening (21), the first scanning wharf (19) and the second scanning wharf (20) at the two sides of the outlet opening (21) automatically scan the information of the expiration card sample, so that the information on the expiration card sample is obtained;
fifth step: after the expiration card sample enters the detection bin from the sample groove (4), the sensor (23) detects that no expiration card sample exists in the sample groove (4), the electromagnet (10) is powered off, so that magnetism of the electromagnet (10) disappears, under the action of the spring (133), the baffle rod (131) is pushed back to the lower part of the sample groove (4) again, and meanwhile, the first rotating disc (2) and the second rotating disc (3) rotate again.
