Ventilated Seat Cushion for Children

Abstract

A ventilated seat cushion for children, comprising a seat cushion (1), air inlet holes (3), air outlet holes (4), a centrifugal fan, and a USB power interface (2), the seat cushion (1) being a hollow structure, the centrifugal fan (3) being provided within the seat cushion (1), the surface of the seat cushion (1) being provided with the air inlet holes (3) and the air outlet holes (4); the negative pressure formed when the centrifugal fan is working enables the air to pass through the air inlet holes (3) and to be suctioned into the seat cushion (1), and the high pressure formed when the centrifugal fan is working enables the air within the seat cushion to pass through the air outlet holes (4) and to be blown out, so as to achieve the effect of circulating heat dissipation; and one end of the seat cushion (1) is provided with a crotch belt perforation opening (B) or a crotch belt gap (A) for a five-point seat belt. The ventilated seat cushion for children has a favorable effect of ventilation and cooling, improving the comfort of children when sitting in a trolley or a car safety seat; the ventilated seat cushion for children can not only be used for a children trolley, but can also be used for a car safety seat for children; and providing seat belt perforation opening (B) can improve the safety of children riding in cars.
