[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0025] like Figure 1-3 As shown, to achieve the above objectives, this utility model provides the following technical solution: an automatic switching special gas control panel, including a housing 1 and a control panel 10. The control panel 10 is installed in the middle of the interior of the housing 1. A limit rod 11 is installed on one side of the bottom of the housing 1. A movable rod 13 is movably installed on the outer surface of the limit rod 11. An outer cover 5 is installed on the top of the movable rod 13. A lifting shaft 17 is installed on the bottom side of the outer cover 5 away from the movable rod 13. A rotating shaft 8 is installed at the bottom of the interior of the housing 1. The rotating shaft 8 is sleeved inside the lifting shaft 17. The rotating shaft 8 and the lifting shaft 17 are connected by a threaded connection. A sealing ring 3 is installed at the bottom of the outer cover 5 to seal the connection. A transparent observation window 4 is installed in the middle of the interior of the outer cover 5.

[0026] like Figure 3 and Figure 4 As shown, an exhaust pipe 7 is installed at the bottom of the control panel 10. An intake manifold B6 is installed at one end of the exhaust pipe 7. An intake manifold A2 is installed on the side of the exhaust pipe 7 near the intake manifold B6. A control valve 19 is installed between the intake manifold A2, the intake manifold B6, and the exhaust pipe 7. A pressure gauge 18 is installed inside the intake manifold A2, the intake manifold B6, and the exhaust pipe 7 near the control valve 19. A display screen 16 is installed on the front surface of the control panel 10. An indicator light 14 is installed on the front surface of the control panel 10 near the display screen 16.

[0027] The working principle of the automatic switching special gas control panel based on Embodiment 1 is as follows: After the present invention is installed, in use, the special gas is delivered through the set air intake branch pipe A2, air intake branch pipe B6 and exhaust pipe 7. At the same time, the gas pressure is monitored by the set pressure gauge 18 and displayed on the display screen 16. When it is necessary to control the special gas, the rotating shaft 8 is rotated, which drives the lifting shaft 17 to move. The lifting shaft 17 drives the outer cover 5 to move up, and then the outer cover 5 is removed. The control valve 19 can be controlled by the control button 12, thereby switching between air intake branch pipe A2 and air intake branch pipe B6.

[0029] In this embodiment, after the temperature sensor 15 senses that the internal temperature of the enclosure 1 exceeds the set value, the fans 20 on both sides are activated. The external air is drawn out by one fan 20 and delivered to the inside of the enclosure 1 through the vent 9. Then, the air inside the enclosure 1 is drawn out by the other fan 20 and discharged through the vent 9, thereby cooling the enclosure 1 and the inside of the control panel 10.
