The suction cylinder 10 is trumpet-shaped and has an open bottom. A connecting hose 7 is installed on the top of the suction cylinder 10, and the end of the connecting hose 7 facing away from the suction cylinder 10 is connected to the bottom of the installation cylinder 5. The position of the suction cylinder 10 is controlled by rotating the screw 8. Corresponding temperature sensors can be arranged on the surface of each device. The position of the suction cylinder 10 can be adjusted by observing the temperature of each device, so that the suction cylinder 10 is placed above the high-heat-generating device.
[0022] Please refer to Figure 2-Figure 4 As shown, a rotating shaft 11 is provided at one end of the screw rod 8, and the rotating shaft 11 is installed on one side of the cabinet body 1 through a bearing. The rotating shaft 11 passes through the outer surface of the cabinet body 1, and a pulley 12 is provided at the end of the rotating shaft 11. The pulley 12 is placed on the outside of the cabinet body 1, and belts 13 are sleeved on the surfaces of the two pulleys 12. The cooperation between the pulleys 12 and the belts 13 can ensure that the two screw rods 8 rotate at the same speed, thereby ensuring the stability of the moving plate 9 when moving.
[0023] Please refer to Figure 2 and Figure 4 As shown, the inner wall of the cabinet 1 is evenly provided with limit convex teeth 14 with one of the rotating shafts 11 as the center, and a slide rod 15 is slidably installed on the inner side of one of the rotating shafts 11, and the slide rod 15 passes through the end surface of the pulley 12, and a knob 16 is provided at one end of the slide rod 15, and a limit rod 18 is vertically provided at the other end of the slide rod 15, and the knob 16 is placed on the outer side of the pulley 12, and the limit rod 18 passes through the arc surface of the rotating shaft 11, and the end of the limit rod 18 is adapted to the limit convex tooth 14, and a spring 17 is sleeved on the surface of the slide rod 15, and one end of the spring 17 is in contact with the surface of the knob 16.

Due to the existence of the spring 17, the knob 16 always has an outward force, which then makes the limit rod 18 cooperates with the corresponding position limiting convex teeth 14 to maintain the stability of the position of the rotating shaft 11. During adjustment, the knob 16 can be pushed inward to make the sliding rod 15 move backward, and the limiting rod 18 moves backward and disengages from the limiting convex teeth 14. At this time, the knob 16 can be rotated to drive the rotating shaft 11 to rotate, and then drive the screw rod 8 to rotate. The outer pulley 12 and the belt 13 cooperate to ensure that the two screw rods 8 rotate synchronously, and then control the movable plate 9 to move horizontally to control the position of the suction tube 10, and adjust the suction tube 10 to be placed on the high heat generation equipment area to improve the heat dissipation effect of individual areas.
