Abstract
The utility model discloses a ventilation system for an electric chair. A first ventilation cavity and a second ventilation cavity that are provided with vent holes are constructed in a backrest assembly and a seat cushion assembly, and a backrest suction device and a seat cushion suction device are arranged in the first ventilation cavity and the second ventilation cavity. By the action of the suction devices, air is sucked out from the first ventilation cavity and the second ventilation cavity, and air pressure in the ventilation cavities is reduced, so that compensation air flows are formed between the first ventilation cavity and a backrest cushion and between the second ventilation cavity and a seat cushion to take away hot air, or sweat moisture and the like generated by a human body, and cooling and dehumidification effects are achieved. According to the ventilation system, the air flows are prevented from directly blowing the human body completely, so that the ventilation system can be used for a long time without undesirable effects. In addition, as the suction devices are arranged in the backrest assembly and the seat cushion assembly, a design effect of compact structure can be achieved. Furthermore, for convenience of adjusting working states of the suction devices timely, suction control boxes are arranged at handrails in order to implement adjustment and control on working of the suction devices.
