[0037] Specifically, a heat insulation layer is provided in contact with the top of the partition plate 105 to block the heat generated when the heating component 4 heats the upper chamber from being transferred to the lower chamber, thereby avoiding affecting the temperature of the storage battery 6 and the PLC controller 7 in the lower chamber and ensuring their safe and stable operation.

[0038] Specifically, the lifting component 8 is used to drive the syringe placement component 9 to rise from the inside of the upper chamber to above the top opening of the upper chamber, facilitating the user to place the syringe and avoiding interference from the side wall of the upper chamber during the syringe placement operation.

[0039] Specifically, the box body 1 further includes a handle 103, a buckle 104, a supporting base 106 and a flow equalizing plate 107. The handle 103 is hinged to both sides of the box body 101.

[0049] Specifically, the heating plate 401 and the thermoelectric cooler 301 are provided for adjusting the temperature in the upper chamber and controlling the temperature of the upper chamber between 20°C and 25°C.

[0050] Specifically, the syringe placement assembly 9 includes a first n-shaped frame 901, a syringe placement plate 902, an angle adjustment assembly 903, a syringe clamping assembly 904, a syringe sliding assembly 905, a second n-shaped frame 906, a positioning guide groove 907, a first pressure sensor 908, a first guide chute 909, a connecting column 910, a second pressure sensor 911, a first guide slider 912, and a second guide chute 913. A plurality of the second guide chutes 913 are symmetrically arranged in pairs on both sides of the first n-shaped frame 901.

[0051] Specifically, the setting of the positioning guide groove 907 plays a role in guiding and positioning the syringe, effectively preventing the syringe from shifting in position when sliding on the syringe placement plate 902.

[0052] Specifically, the first pressure sensor 908 is used to monitor whether the syringe is placed on the positioning guide groove 907. After the medical staff completes the collection of the animal blood sample, the syringe containing the blood sample is placed in the corresponding positioning guide groove 907 on the syringe placement plate 902, and the bottom end of the finger clamping part of the syringe is made to contact the working end of the syringe sliding assembly 905. At this time, the gravity of the syringe acts on the first pressure sensor 908, and the first pressure sensor 908 transmits the generated electrical signal to the PLC controller 7. The PLC controller 7 controls the syringe sliding assembly 905 to slide upward along the first guide chute 909, and at the same time drives the whole syringe to slide upward along the positioning guide groove 907 by pushing the finger clamping part of the syringe until the needle part of the syringe passes through the gap between the two support arms of the second n-shaped frame 906, and one end of the syringe barrel close to the needle contacts the second pressure sensor 911 on the second n-shaped frame 906. At this time, the electrical signal generated by the second pressure sensor 911 is transmitted to the PLC controller 7, and the PLC controller 7 controls the syringe sliding assembly 905 to stop working and controls the syringe clamping assembly 904 to slide down to press and position the syringe on the syringe placement plate 902 to prevent the position of the syringe from shifting.

[0053] Specifically, the angle adjustment assembly 903 is used to adjust the inclination angle of the syringe placement plate 902, and the angle adjustment range of the syringe placement plate 902 is 0° to 60°.

[0054] Specifically, the angle adjustment assembly 903 includes a third n-shaped frame 9031, a second drive motor 9032, a first gear 9033 and a second gear 9034. The open end of the third n-shaped frame 9031 is fixedly connected to the bottom of the first n-shaped frame 901. The second drive motor 9032 is installed at the closed end of the third n-shaped frame 9031.

The first gear 9033 is fixedly connected to one side of the first n-shaped frame 901 close to the second gear 9034, and the second gear 9034 is in meshing transmission with the first gear 9033. A connecting column 910 provided on one side of the syringe placement plate 902 close to the first gear 9033 passes through the central position of the first gear 9033 and is rotationally connected to the first n-shaped frame 901. The second drive motor 9032 is electrically connected to the PLC controller 7.

[0055] Specifically, the syringe clamping assembly 904 includes a linear motor 9041, a fourth n-shaped frame 9042, a clamping block 9043, second guide posts 9044, a limit block 9045, and a spring 9046. An avoidance hole matching the opening end of the fourth n-shaped frame 9042 is formed on the syringe placement plate 902. The fourth n-shaped frame 9042 is slidably and embeddedly connected to the syringe placement plate 902 through the avoidance hole, and the closed end of the fourth n-shaped frame 9042 is located above the syringe placement plate 902. The linear motor 9041 is fixedly connected to the bottom of the syringe placement plate 902, and the telescopic end of the linear motor 9041 passes through any one of the avoidance holes and is fixedly connected to the corresponding side of the opening end of the fourth n-shaped frame 9042, and is used to drive the fourth n-shaped frame 9042 to perform a lifting movement in the height direction. The two second guide posts 9044 are respectively arranged on the left and right sides of the closed end of the fourth n-shaped frame 9042, and one end of the second guide post 9044 slidably passes through the fourth n-shaped frame 9042 and is fixedly connected to the clamping block 9043.

The spring 9046 is sleeved on the second guide post 9044, and the two ends of the spring 9046 are respectively abutted against the opposite surfaces of the clamping block 9043 and the fourth n-shaped frame 9042. The linear motor 9041 is electrically connected to the PLC controller.

[0056] Specifically, the two second guide posts 9044 are respectively arranged on the left and right sides of the fourth n-shaped frame 9042, and both form an angle of 45 degrees with the horizontal plane, and their axial directions intersect at a point; the inside of the clamping block 9043 is arranged as a concave surface, which matches the shape of the syringe barrel.

[0057] Specifically, during use, when the syringe moves to a preset position, the linear motor 9041 drives the fourth n-shaped frame 9042 to slide downward, thereby driving the fourth n-shaped frame 9042, the second guide posts 9044, the spring 9046 and the clamping block 9043 to move downward as a whole. When the fourth n-shaped frame 9042 moves downward to the lowest working position, the concave surface of the clamping block 9043 abuts against the syringe barrel, and gradually compresses the spring 9046, so as to apply a pre-tightening force for the positioning of the syringe.

[0058] Specifically, a rubber layer is attached to the concave surface of the clamping block 9043 to enhance the clamping effect and protect the surface of the syringe barrel.

[0059] Specifically, the number of the syringe clamping assemblies 904 matches the number of the positioning guide grooves 907 to ensure that each syringe can be accurately clamped and positioned.

[0060] Specifically, the second guiding column 9044, the spring 9046 and the clamping block 9043 are arranged such that the syringe clamping assembly 904 can be applicable to the pressing and fixing operations of syringes with different diameter specifications.

[0061] Specifically, the syringe sliding assembly 905 includes a fifth n-shaped frame 9051, a third driving motor 9052 and a second reciprocating lead screw 9053. The fifth n-shaped frame 9051 is slidably connected to the syringe placement plate 902 through the first guiding chute 909, and the open end of the fifth n-shaped frame 9051 penetrates through the syringe placement plate 902 and extends upward. The third driving motor 9052 is installed in the installation groove at the bottom of the syringe placement plate 902. One end of the second reciprocating lead screw 9053 is rotatably connected to one side of the installation groove, and the other end of the second reciprocating lead screw 9053 is fixedly connected to the power output end of the third driving motor 9052. The second reciprocating lead screw 9053 is arranged parallel to the direction of the positioning guiding groove 907. The closed end of the fifth n-shaped frame 9051 is threadedly connected to the second reciprocating lead screw 9053. The third driving motor 9052 is electrically connected to the PLC controller 7.

[0062] Specifically, the lifting assembly 8 includes a first driving motor 801, a first reciprocating lead screw 802, a first threaded block 803, a first guiding column 804 and a first guiding sliding sleeve 805. One end of the first guiding column 804 is fixedly connected to the top of the supporting base 106, and the other end of the first guiding column 804 is fixedly connected to the side wall of the upper chamber through a connecting plate. The first driving motor 801 is installed at the bottom of the upper chamber and is located on the opposite side of the first guiding column 804. One end of the first reciprocating lead screw 802 is fixedly connected to the power output end of the first driving motor 801, and the other end of the first reciprocating lead screw 802 penetrates through the supporting base 106 and is rotatably connected to the connecting plate fixed on the side wall of the upper chamber. The first threaded block 803 and the first guiding sliding sleeve 805 are respectively arranged on the left and right sides of the first n-shaped frame 901. The first threaded block 803 is threadedly connected to the first reciprocating lead screw 802, and the first guiding sliding sleeve 805 is slidably sleeved on the first guiding column 804. The first driving motor 801 is electrically connected to the PLC controller 7.

[0063] The usage process of the present invention is as follows:

[0064] First, the user starts the device through the power switch 202 on the control panel 2. The display screen 201 will show the temperature inside the upper chamber. If the temperature is not within the preset range of 20°C to 25°C, the user can set the target temperature by adjusting the knob 203 or the digital buttons 204. The PLC controller 7 will automatically control the refrigeration component 3 or the heating component 4 to work according to the signal fed back by the temperature sensor, so as to adjust the temperature inside the upper chamber to the set value;

[0065] Secondly, after the temperature reaches the set range, the user can start the lifting component 8 through the control panel 2. The first driving motor 801 drives the first reciprocating lead screw 802 to rotate, driving the first threaded block 803 and the first guiding sliding sleeve 805 to move up and down, so that the syringe placement component 9 moves up and down inside the upper chamber. When the syringe placement component 9 rises above the top opening, the user can conveniently place the syringe in the positioning guiding groove 907 on the syringe placement plate 902;

[0066] Thirdly, after the syringe is placed, the first pressure sensor 908 will sense the gravity of the syringe and transmit the signal to the PLC controller 7. The PLC controller 7 controls the syringe sliding component 905 to work. The third driving motor 9052 drives the second reciprocating lead screw 9053 to rotate, driving the fifth n-shaped frame 9051 to slide upward along the first guiding chute 909, and pushing the finger clamping part of the syringe, so that the whole syringe moves upward. When the needle part of the syringe passes through the gap between the two support arms of the second n-shaped frame 906 and the end of the syringe barrel near the needle contacts the second pressure sensor 911, the second pressure sensor 911 transmits the signal to the PLC controller 7, and the PLC controller 7 controls the syringe sliding component 905 to stop working;

[0067] Then, the PLC controller 7 controls the syringe clamping component 904 to descend. The linear motor 9041 drives the fourth n-shaped frame 9042 to slide downward, driving the clamping block 9043 to abut against the syringe barrel, and applying a pre-tightening force through the spring 9046 to press and position the syringe on the syringe placement plate 902 to prevent the position of the syringe from shifting;

[0068] Finally, the user can adjust the tilt angle of the syringe placement plate 902 through the control panel 2. The second driving motor 9032 drives the second gear 9034 to mesh with the first gear 9033 fixedly connected to the side wall of the first n-shaped frame 901, thereby driving the syringe placement plate 902 to rotate around the connecting column 910, so that its tilt angle can be adjusted within the range of 0° to 60°, facilitating the tilting placement operation of the syringe;

[0069] In addition, during the entire usage process, multiple second fans 5 and the flow equalizing plate 107 work together to ensure uniform air flow and balanced temperature distribution in the upper chamber. The refrigeration component 3 and the heating component 4 adjust the temperature in the upper chamber in real time according to the instructions of the PLC controller 7 to ensure that the blood samples are stored in a suitable temperature environment.
