The present utility model relates to a ventilated seat cushion for children.
In daily life, children will often encounter the situation of sitting in a child trolley, or using a child safety seat, etc. The traditional child trolley seat cushions and safety seat cushions for children are common with poor ventilation and heat dissipation. Especially in summer, buttocks and backs of children often get sweaty or even worse having eczema and other symptoms. While affecting the health of the children, it will further bring hidden security dangers due to the poor self-control of the children and psychological resistance to the seat.
The current available cooling solution for child seat cushions is to put ice mats or cooling mats on the child trolley or the safety seat to alleviate the poor heat dissipation. However, the trolley cushion or the safety seat cushion has sufficient softness and elasticity, causing the ice mat or the cooling mat to be pressed into the cushion by the pressure of the children body and most of the ventilation holes being blocked, thereby reducing the effectiveness of convection heat transfer. Furthermore, the cooling measures such as cooling mats will be completely ineffective when the children's travelling time takes a bit longer.
In the field of automotive supplies, there are ventilated seat cushions for adults which have fans to blow air and form a forced air circulation to cool the buttocks and the back. However, it is not suitable for children because it is designed for adults. For example, the seat cushion for adults is powered by a 12v car Cigar Lighter and cannot be used for a child trolley; its fixing mode is not designed to consider the features of the five-point seat belt of children and is inconvenient for installation.
In light of the above-mentioned technical issues, the present utility model is to provide a ventilated seat cushion for children which is suited for solving the discomfort of riding in the scorching weather for children.
