DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0025] like Figure 1 、 Figure 2 、 Figure 3As shown, the device includes a shed body 1 and a sealing plate 2. The sealing plate 2 is arranged at the front end of the exterior of the shed body 1, and the left side of the sealing plate 2 is hinged to the shed body 1 and the right side is connected to the shed body 1 by a lock. A number of shells 3 are fixed on the left and right sides of the interior of the shed body 1 from front to back. A temperature control component 4 is provided inside the shell 3. The temperature control component 4 includes a partition 401 fixed at the upper and lower ends of the interior of the shell 3. A semiconductor refrigerator 402 is fixed at the upper end of the interior of the shell 3. The semiconductor refrigerator 402 is fixedly passed through the shed body 1. A heating pipe 403 is fixed at the lower end of the interior of the shell 3. A heat conducting plate 404 made of copper material is fixed at the upper and lower ends of the interior of the shell 3. A clearance hole 405 is integrally provided at the upper and lower ends of the interior of the shell 3. A motor 406 is fixed at the middle end of the interior of the shell 3. A rotating rod 407 fixed on the inner side of the motor 406 rotates and passes through the shell 3. A retaining ring 408 is fixed on the outer sleeve of the rotating rod 407, and a avoidance hole 409 is integrally provided inside the retaining ring 408.

[0026] The shell 3, the retaining ring 408 and the partition 401 are made of non-metallic heat-insulating materials. The retaining ring 408 and the shell 3 are designed to fit each other. The clearance hole 405 and the avoidance hole 409 are through-hole designs. The outer wall of the shell 3 is fixed with a temperature sensor 5. The outer wall of the shell 3 is fixed with a controller 6. The controller 6 is connected to the temperature sensor 5 and the motor 406 through a wire. First, the temperature sensor 5 monitors the temperature inside the shed 1. When the temperature inside the shed 1 is higher than the value set by the temperature sensor 5, the semiconductor cooler 402 and the motor 406 are turned on. The semiconductor cooler 402 cools the heat conducting plate 404 at the upper end of the shell 3, and the motor 406 controls the rotating rod 407 to drive the retaining ring 408 together with the avoidance hole 409 and the clearance hole 405 at the upper end of the shell 3, thereby exposing the cooled heat conducting plate 404 at the upper end of the shell 3 to the outside world. At this time, the heat conducting plate 404 at the upper end is 4 absorbs the heat inside the shed body 1, thereby achieving a cooling effect. When the temperature inside the shed body 1 is lower than the value set by the temperature sensor 5, the heating tube 403 and the motor 406 are turned on, and the heating tube 403 heats the heat conducting plate 404 at the lower end of the shell 3. The motor 406 controls the rotating rod 407 to drive the retaining ring 408 together with the avoidance hole 409 to overlap with the avoidance hole 405 at the lower end of the shell 3, so that the heated heat conducting plate 404 at the lower end of the shell 3 transfers heat to the inside of the shed body 1, thereby achieving a heating effect. Example 2

[0027] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, a first metal sensor 7 is fixedly provided at the upper end of the shell 3, a second metal sensor 8 is fixedly provided at the lower end of the shell 3, and a third metal sensor 9 is fixedly provided at the middle end of the shell 3. The first metal sensor 7, the second metal sensor 8 and the third metal sensor 9 are designed to be distributed around the axis of the rotating rod 407, and the first metal sensor 7, the second metal sensor 8 and the third metal sensor 9 are connected to the controller 6 through a wire. The first metal sensor 7 and the second metal sensor 8 are in a mirror design state, and the angle between the third metal sensor 9 and the first metal sensor 7 and the second metal sensor 8 is 90 degrees. An induction sheet 10 is fixedly provided inside the retaining ring 408, and the induction sheet 10 and the avoidance hole 409 are in a mutually staggered design. The induction sheet 10 is made of metal, and a connecting sleeve 11 is fixedly passed through the left and right sides of the middle end of the shed 1, and an electromagnetic valve 12 is fixed inside the connecting sleeve 11, and an exhaust fan 13 is fixed inside the connecting sleeve 11 on the right.

[0028] According to the operating method in Example 1, when the temperature sensor 5 controls the semiconductor refrigerator 402 and the motor 406 to turn on, the first metal sensor 7 is turned on at the same time. When the retaining ring 408 drives the sensing plate 10 to coincide with the first metal sensor 7, the first metal sensor 7 detects the sensing plate 10 and the motor 406 stops running, thereby accurately controlling the state in which the avoidance hole 409 and the upper end of the clearance hole 405 coincide with each other. When the temperature sensor 5 controls the heating tube 403 and the motor 406 to turn on, the second metal sensor 8 is turned on at the same time. When the retaining ring 408 drives the sensing plate 10 to coincide with the second metal sensor 8, the second metal sensor 8 detects the sensing plate 10 and the motor 406 stops running, thereby accurately controlling the state in which the avoidance hole 409 and the lower end of the clearance hole 405 coincide with each other. When the temperature inside the shed 1 reaches the value set by the temperature sensor 5, the semiconductor cooler 402 or the heating tube 403 stops working, and the motor 406 and the third metal sensor 9 are turned on. When the retaining ring 408 drives the induction plate 10 to overlap with the third metal sensor 9, the third metal sensor 9 detects the induction plate 10 and the motor 406 stops running, thereby misaligning the avoidance hole 409 with the upper and lower end clearance holes 405. The retaining ring 408 isolates the heat conducting plate 404 from the outside world. In addition, according to actual usage, the staff can open the solenoid valve 12 and the exhaust fan 13 to discharge the outside air into the shed 1 through the left connecting sleeve 11. The air inside the shed 1 is then discharged to the outside through the right connecting sleeve 11, thereby regularly exchanging the air inside the shed 1 with the outside air.
