All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to FIGS. 1-5, the present invention provides

A cushion ventilation and heat dissipation office chair comprises a movable base 1 and a rotary chair 2, wherein a rotary shaft fixing seat 3 is arranged on the movable base 1, a rotary shaft body 4 is arranged on the lower surface of the rotary chair 2, the rotary shaft body 4 is installed in the rotary shaft fixing seat 3 to rotate, a plurality of heat dissipation holes 5 are formed in the rotary chair 2, piston assemblies 6 are symmetrically arranged at the bottom of the rotary chair 2 in the left-right direction, ventilation pipelines 7 are arranged between the piston assemblies 6 and the heat dissipation holes 5, and a linkage assembly 8 capable of driving the piston assemblies 6 to move in the rotating process of the rotary chair 2 is arranged between the rotary shaft fixing seat 3 and the rotary chair 2;

the above structure principle:

hip is sat swivel seat 2 is time, rotatory swivel seat 2, swivel seat 2 drives pivot body 4 for pivot fixing base 3 rotates, at this moment, and is a plurality of piston assembly 6 centers on pivot fixing base 3 carries out the rotation action, through linkage subassembly 8 is in 2 rotatory processes of swivel seat drive piston assembly 6 carries out the pull action, and right air pipe 7 carries out convulsions and air supply action, realizes air pipe 7's heat exchange, reduces the temperature in air pipe 7, and air supply process stroke is from a plurality of simultaneously heat dissipation hole 5 blows out, reduces the temperature of hip.
