The calibration liquid feeding mechanism 3 is arranged on the supporting mechanism 1 and can crush the calibration liquid bag so that the calibration liquid in the calibration liquid bag flows to the electrode plate 211 of the detection card 2. The heating mechanism 4 is provided on the support mechanism 1 and located below the detection card 2, and can heat the electrode plate 211. The sample liquid feeding mechanism 5 is disposed on the supporting mechanism 1 and below the detection card 2, and can extrude the air bag, and blow the sample liquid in the sample introduction region 22 of the detection card 2 to the electrode plate 211 of the detection card 2 by using the gas in the air bag. The driving mechanism 6 can drive the sample liquid feeding mechanism 5 and the heating mechanism 4 to ascend or descend along the vertical direction, and it can be understood that when the driving mechanism 6 drives the sample liquid feeding mechanism 5 to ascend, the sample liquid feeding mechanism 5 can press the air bag, so that the sample liquid in the sample introduction area 22 of the detection card 2 is blown to the electrode plate 211 of the detection card 2 by the gas in the air bag. When the heating mechanism 4 is driven by the driving mechanism 6 to move up and come into contact with the detection card 2, the electrode plate 211 on the detection card 2 can be heated.

Specifically, as shown in fig. 3, the supporting mechanism 1 includes a supporting frame 11, the supporting frame 11 is a cubic frame structure, and the top of the supporting frame 11 has two first arms oppositely spaced from each other, a mounting groove 111 is provided between the two first arms, and the mounting groove 111 is used for mounting the detection card 2. In order to facilitate the sample liquid feeding mechanism 5 below the detection card 2 to extrude the air bag on the detection card 2, a notch 112 is formed on the bottom plate of the mounting groove 111 at a position corresponding to the air bag.

After the calibration liquid package is crushed, the calibration liquid in the calibration liquid package flows to the electrode plate area 21 along the groove between the calibration liquid inlet area 23 and the electrode plate area 21. It can be understood that in order to avoid the influence of the external environment on the measurement result, the electrode plate area 21 is designed to be a relatively closed space, so that the sample liquid injected into the sample injection area 22 needs to be pushed by an external force to flow to the electrode plate area 21, and therefore, the bottom of the detection card 2 is provided with an air bag, the air bag is pressed by the sample liquid feeding mechanism 5, and the sample liquid in the sample injection area 22 is blown to the electrode plate area 21 by the gas in the air bag.

As shown in fig. 2 and 5, in order to further simplify the structure of the calibration liquid, sample liquid feeding and heating apparatus, in the present embodiment, both the heating mechanism 4 and the sample liquid feeding mechanism 5 are driven by the driving mechanism 6. Specifically, the heating mechanism 4 includes a carrier plate 41 and a mounting table 42 disposed on the carrier plate 41, the mounting table 42 corresponds to the electrode plate 211 in the detection card 2, and a heating member (not shown in the figure) is mounted on the mounting table 42, and when the heating mechanism 4 is driven by the driving mechanism 6 to ascend, so that the heating member abuts against the detection card 2, the heating member can heat the electrode plate 211.

The guide posts 12 are inserted into the driving plate 51 and the carrier plate 41, and the four guide posts 12 are respectively located at four corners of the driving plate 51, it can be understood that the driving plate 51 and the carrier plate 41 can slide along the guide posts 12 under the driving of the driving mechanism 6. In order to realize that the driving plate 51 and the bearing plate 41 can be driven by the driving mechanism 6, a first elastic member 14 is arranged between the driving plate 51 and the bearing plate 41, a second elastic member 15 is arranged between the bearing plate 41 and the first arm of the supporting frame 11, the first elastic member 14 and the second elastic member 15 extend along the vertical direction, and the elastic coefficient of the first elastic member 14 is smaller than that of the second elastic member 15. In this embodiment, the first elastic element 14 and the second elastic element 15 are both springs, and the first elastic element 14 and the second elastic element 15 are both sleeved on the guide post 12. It can be understood that, in order to enable the driving plate 51 and the carrier plate 41 to stably move, each guide post 12 is sleeved with the first elastic member 14 and the second elastic member 15.

By setting the elastic coefficient of the first elastic member 14 to be smaller than that of the second elastic member 15, when the driving mechanism 6 drives the driving plate 51 to ascend, the second elastic member 15 can be contracted first, at this time, the driving plate 51 and the bearing plate 41 ascend together until the heating member on the bearing plate 41 abuts against the detection card 2, at this time, the second elastic member 15 reaches the maximum compression amount, and the heating member can heat the electrode plate 211. Then, the driving plate 51 continues to ascend, and the first elastic member 14 starts to contract because the second elastic member 15 has reached the maximum compression amount, at which time the driving plate 51 ascends alone, and the pressing blocks 52 contact and press the air bag through the through holes 411 and the notches 112 in sequence.

The driving plate 51 is provided with a sliding piece 511, the sliding piece 511 can abut against a step surface or an inclined surface 624, and when the first driving piece 61 drives the driving block 62 to move along the first direction, the sliding piece 511 can slide along the inclined surface 624 or the step surface and gradually ascend or descend.

Specifically, for convenience of description, three step surfaces with gradually increasing heights are sequentially defined as a first step surface 621, a second step surface 622, and a third step surface 623, and when the first driver 61 drives the driving block 62 to move away from the first driver 61, the sliding member 511 rises from the first step surface 621 to the second step surface 622, and at this time, the heating member abuts against the detection card 2 to heat the electrode plate 211, that is, the height difference between the first step surface 621 and the second step surface 622 is equal to the maximum compression amount of the second elastic member 15. When the first driving element 61 continues to drive the driving block 62 to move away from the first driving element 61, the sliding element 511 gradually rises from the second step surface 622 to the third step surface 623, and in the process, the squeezing block 52 passes through the through hole 411 and the notch 112 to contact with the air bag and squeeze the air bag, so that the sample liquid in the sample injection region 22 is blown to the electrode plate region 21.

In order to reduce the friction between the sliding member 511 and the step surface and the inclined surface 624, it is preferable that the sliding member 511 is a roller in this embodiment, but in other embodiments, the sliding member 511 may be a slider having an arc-shaped surface to reduce the contact area between the sliding member 511 and the step surface or the inclined surface 624 as much as possible.
