Abstract
A heat ventilating chair includes a backrest unit, a seat unit, and a connecting unit connecting the backrest unit to the seat unit. One of the backrest unit and the seat unit includes a hollow member having an air pump, a pressure valve, and a channel that communicates fluidly the air pump and the pressure valve. The connecting unit is connected between the air pump and the other one of the backrest unit and the seat unit. The connecting unit drives the air pump to expel hot air in the channel to the ambient via the pressure valve when the backrest unit is forced to incline rearward. The connecting unit drives the air pump to draw ambient cool air into the channel via the pressure valve when the backrest unit is restored from a rearwardly inclined state.
