The length L of the evaporator of the internal machine is the path the take-up device travels from point a in fig. 8 in the first direction to point B in fig. 9.

In this embodiment, a second spur gear 16 is disposed near the first spur gear 14, the second spur gear 16 is meshed with the first spur gear 14, and the first spur gear 14 rotates to drive the second spur gear 16 to rotate. The first lead screw nut 18 is disposed in the spur gear cover 21, and the first lead screw nut 18 is connected to the spur gear cover 21. The first screw nut 18 rotates clockwise or counterclockwise, converting the circular motion of the first screw nut 18 into the linear motion of the spur gear cover 21 on the second screw 17. The spur gear cover 21 drives the motor cover 20 to horizontally move on the second screw 17, thereby driving the lamp housing 4 to move in the first direction or the third direction.
