[0041] The same type of temperature-controlled chamber unit can be included in the constant-temperature chamber module, or different types of temperature-controlled chamber units can be included, such as four heating chamber units, or two heating chamber units and two room temperature chamber units.
[0042] The heating plate is wrapped around the outside of the first chamber body, which facilitates uniform heating of the first chamber body and maintains the stability of the temperature of the first chamber body. Even if the chamber door is opened briefly, it will not cause fluctuations in the temperature of the first chamber body. The heating chamber unit can also be implemented through other structures, such as adjusting the position of the heating plate, adjusting the position of the first temperature sensor, adjusting the number of test tube holes, etc.
[0043] In an embodiment of the present application, as shown in Figure 4 and Figure 6 The plurality of temperature-controlled chamber units include a room temperature chamber unit 120.
[0044] The room temperature chamber unit 120 includes a second outer plate 121, a second heat insulation plate 122, a second chamber body 123, a heat conduction block 124, a semiconductor refrigeration sheet 125, a heat dissipation fin 126, an axial flow fan 127, a second temperature sensor 128, a second heat preservation layer 129, and a test tube hole 131. The axial flow fan 127 is installed outside the heat dissipation fin 126.
[0045] When the semiconductor refrigeration sheet 125 is forward energized, the side of the semiconductor refrigeration sheet 125 in contact with the second chamber body 123 is the cold end, and the side of the semiconductor refrigeration sheet 125 in contact with the heat dissipation fin 126 is the hot end.

This phenomenon is completely reversible, and heat can be transferred in the opposite direction by simply changing the direction of the current.

The temperature of the refrigeration chamber unit 130 is lower than that of the room temperature chamber unit 120.
[0051] Since the refrigeration chamber unit and the room temperature chamber unit have the same structure, the structure of the refrigeration chamber unit can be referred to Figure 6 , and the present application will not be described again. Unlike the room temperature chamber unit, the temperature of the refrigeration chamber unit is lower, for example, the temperature of the room temperature chamber unit is controlled at about 25°C, and the temperature of the refrigeration chamber unit is controlled at about 10°C.

[0054] When the control unit 001 controls the electric push rod motor 221 to move the push rod forward based on the angle adjustment instruction, the pull rod 220 moves forward synchronously, the front connecting rod slider 216 also moves forward synchronously, the front connecting rod 218 pulls the upper base plate 211 to overturn around the overturning shaft 213 to the horizontal position, the connecting rod 217 pushes the rear connecting rod slider 215 to move backward, the booster tension spring 222 is pulled open, until the upper base plate 211 moves to the horizontal state, the horizontal limit position sensor 223 is activated, sends a first feedback signal to the control unit 001, and the control unit 001 controls the electric push rod motor 221 to stop moving based on the first feedback signal.

[0058] The rotating motor 306 is flange-fixed on the support frame 302, the small pulley 303 is connected to the output shaft of the rotating motor 306, and when the rotating motor 306 rotates, the power is transmitted to the large pulley 304 through the friction between the small pulley 303 and the large pulley 304 via the belt 305. The eccentric shaft 307 is distributed between the circumferential oscillation table 301 and the support frame 302, providing three-point circumferential rotation support for the circumferential oscillation table 301. The eccentric shaft 307 and the circumferential oscillation table 301, and the eccentric shaft 307 and the support frame 302 are connected by rotating pairs. The output shaft of the large pulley 304 is fixedly connected to one of the eccentric shafts 307.
[0059] The control unit 001 controls the rotating motor 306 to rotate based on the oscillation instruction, driving the circumferential oscillation table 301 to move.
[0060] The circumferential oscillation table 301 is fixedly connected with the lower base plate 212, the upper base plate 211 is fixedly connected with the constant-temperature bin module 100, and the control unit 001 controls the rotation speed of the rotating motor 306, so as to realize the circumferential vibration frequency control of the constant-temperature bin module 100. Since the large pulley 304 output shaft is fixedly connected with one of the eccentric shafts 307, the power on the large pulley can drive the eccentric shaft 307 to rotate, so that the circumferential oscillation table 301 also rotates around the center of the eccentric shaft 307, forming a circumferential oscillation track. Among them, the size ratio of the large pulley can improve the output torque on the large pulley.
