[0020] The control mechanism includes a first control switch 7, a second control switch 8, a fixed tube 9, a piston 10, a movable rod 11, and an extrusion block 12. The first control switch 7 is fixedly arranged on one side of the lower end of the functional compartment 6, and the second control switch 8 is fixedly arranged on the upper end of the first control switch 7 in the functional compartment 6. The fixed tube 9 is fixedly arranged on one side of the first control switch 7 in the functional compartment 6, and a piston 10 is movably engaged in the fixed tube 9. The movable rod 11 is fixedly arranged on the upper end of the piston 10, and the extrusion block 12 is fixedly arranged on the upper end of the movable rod 11. The operation of the heating wire 5 can be controlled by the control mechanism; and the whole process is automatically controlled based on thermal expansion and contraction; it is easy to use;

[0021] The extrusion block 12 is disposed between the first control switch 7 and the second control switch 8, so that when the extrusion block 12 moves downward, the first control switch 7 can be squeezed, and when the extrusion block 12 moves upward, the second control switch 8 can be pushed;

[0022] The lower end of the fixed tube 9 is filled with mercury liquid, and the mercury liquid can drive the movable rod 11 and the extrusion block 12 to move up and down when the temperature changes through the principle of thermal expansion and contraction; thus, the extrusion block 12 can be used to squeeze the first control switch 7 or push the second control switch 8 to control the operation of the heating wire 5;

[0023] The first control switch 7 is electrically connected to the second control switch 8 and the heating wire 5. The first control switch 7 of the device controls the heating wire 5 to be powered on, while the second control switch 8 of the device controls the heating wire 5 to stop working.

[0025] Working principle: When the device is used, the copper tube 2 of the device is used to flow the refrigerant, and the device is provided with a heat conducting rod 4 and a heating wire 5 at the circulation bend of the copper tube 2. Thus, when the temperature is lower than the threshold, there is no need to release the refrigerant inside the copper tube 2, and the heating wire 5 can be energized, so that the copper tube 2 and the refrigerant inside can be heated, thereby effectively preventing the temperature of the refrigerant from dropping below the threshold, so as to play an antifreeze role for the entire device;

When the temperature reaches the threshold, the squeezing block 12 can squeeze the first control switch 7, so that the heating wire 5 can be powered on. As the heating wire 5 is powered on and the ambient temperature rises, the temperature near the fixed tube 9 will slowly rise. At this time, the mercury will expand again, so that the squeezing block 12 can squeeze the second control switch 8, so that the heating wire 5 can be stopped. In this way, the heating wire 5 of the device can work conveniently and quickly, and the whole process is automatically controlled based on thermal expansion and contraction. It is easy to use.
