Description

Technical Field

[0001] The present application relates to the technical field of auto shows, and in particular to an auto show ventilation system. Background Art

[0002] Auto shows are a display of automotive technology and an advertisement for automotive products, as well as a public relations exercise between auto manufacturers and local dealers. Consumers can observe the development trends of the automotive manufacturing industry through the cars or automotive-related products displayed at auto shows.

[0003] When vehicles are displayed at a car show, many exhibitors will stay near the booths to view the cars. However, common ventilation devices are mostly installed on the walls and ceilings, which cannot accurately deliver fresh air to the people gathered at the booths. At the same time, due to the large number of people near the booths, the smell of exhaled gas and volatile sweat can easily spread near the booths, making subsequent visitors uncomfortable.

The setting of the blocking rod 19 can prevent people from entering the rotating platform 4. The outer surface of the rotating shaft 3 is rotatably connected with a cam 5 through a one-way bearing.

[0034] See also Figure 1 , Figure 2 and Figure 6 In addition, when the rotating shaft 3 rotates forward, the one-way bearing is locked, and when the rotating shaft 3 rotates reversely, the one-way bearing is in an active state. The outer surface of the cam 5 contacts with two squeezing balls 6, and the two squeezing balls 6 are fixedly connected to the squeezing rods 7 on the sides away from each other. The two squeezing rods 7 are fixedly connected to the pistons 8 on the ends away from each other. The outer surfaces of the two pistons 8 are sleeved with suction cylinders 9, and the outer surfaces of the two suction cylinders 9 are fixedly connected to stabilizing blocks. The two stabilizing blocks are fixedly connected to the inner top wall of the booth 2. Through the setting of the stabilizing blocks, the purpose of fixing the suction cylinders 9 can be achieved.

[0037] In the present embodiment, a car show ventilation system can accurately ventilate the air near the booth 2 by providing an air ring 12 and an air nozzle 13. At the same time, the vehicles can be rotated for display by the provided turntable 4, making it more convenient for exhibitors to watch. During the rotation of the turntable 4, the suction tube 9 can be linked to absorb the fragrance and release it near the booth 2, and the air nozzle 13 can be used to quickly diffuse the fragrance, thereby improving the comfort level of the car show environment.

[0038] It should be noted that the other end of the ventilation pipe 15 is connected to an external air supply device, and the bottom end of the rotating shaft 3 is connected to an external forward and reverse motor output end.

[0039] The working principle of the above embodiment is as follows: by connecting the ventilation pipe 15 with the external air supply device, the external air is transported into the air ring 12 and sprayed out through the air nozzle 13, so that fresh air can be transported to the vicinity of the booth 2. By starting the external motor to drive the rotating shaft 3 to reverse, the rotating table 4 can be driven to rotate, and the vehicle can be displayed in rotation, which is convenient for visitors to observe various parts of the car in situ. By rotating the rotating shaft 3 forward, the cam 5 can be locked, thereby driving the cam 5 to rotate, squeezing the two squeezing balls 6 to drive the piston 8 to move, and the aromatherapy liquid in the aromatherapy box 14 can be absorbed and sprayed on the inside of the rotating table 4. The fragrance is released through the aromatherapy port and diffused through the airflow of the air nozzle 13, so as to purify the air near the booth 2 and improve the comfort of visitors.
