[0002] In the current market of household goods and baby products, ventilated cushions are a product designed to improve user comfort, especially in strollers and safety seats, and their popularity is gradually increasing. However, although this type of product is popular for its ability to effectively relieve the stuffiness caused by long-term riding, a deep analysis of its internal structure reveals a common problem: the layout and design of the internal fans of existing ventilated cushions on the market are relatively simple and lack humanized considerations. For example, the Chinese patent with the authorization announcement number CN205963523U discloses a ventilated cushion, which simply embeds the fan module in a certain position of the cushion, without fully considering the integration of the fan and the overall structure of the cushion, as well as the noise control and airflow distribution uniformity of the fan during operation. This simple placement method may not only affect the service life and efficiency of the fan, but also lead to poor user experience due to uneven airflow distribution, such as discomfort caused by excessive wind in some areas, while other areas can hardly feel the cool breeze. In-depth consideration and design of the internal fan of the ventilated cushion and its ease of use have become an important direction to improve product competitiveness and meet market demand.

[0033] Working principle: At the bottom end of the Oxford cloth layer 6 of the cushion, there is a fan pocket 1 for placing the fan. The inner lining of this pocket is a strap structure, and the material is Oxford cloth. The size of the inner pocket sewn with the strap Oxford cloth is the same as the size of the fan, which is used to place and fix the position of the fan. The fan is not easy to shake inside the strap structure. The opening of the pocket, that is, the bottom end of the strap Oxford cloth structure, is provided with a mesh pocket 8 structure. The bottom end of the mesh pocket 8 is sewn on the cushion. There is a position for Velcro on the top of the mesh pocket 8, and there is also Velcro at the corresponding position of the cushion.
