It can be understood that the cooling fan 110 faces the breathable net through the upper end of the ventilation hole 120. When heat dissipation is needed, the cooling fan 110 is started. Under the action of the cooling fan 110, the wind enters the ventilation hole 120 through the lower end of the ventilation hole 120 and then blows toward the breathable net from the upper end of the ventilation hole 120. Compared with natural heat dissipation, the heat dissipation effect is better. At the same time, the wind blows toward the breathable net in an orderly manner from bottom to top. Compared with chaotic and disordered air supply, the heat dissipation effect is better.

[0031] The ventilation holes 120 can be integrally formed by injection molding when processing the seat cushion frame 100 , or can be processed on the seat cushion frame 100 later by cutting, drilling, and the like.

[0032] Please refer to Figure 1-2 and Figure 5-7 As shown, the present embodiment also includes a hard mesh structure 190; the air outlet and air inlet of the cooling fan 110 correspond to the upper and lower ends of the ventilation hole 120 respectively, ensuring that the shell 111 also exhausts air from bottom to top, and can achieve the shortest path of air inlet and outlet relative to the lateral air intake of the cooling fan 110; the air outlet and air inlet of the cooling fan 110 are also covered by the mesh structure 190; the fan blades 112 are prevented from hurting the breathable net and the user, and the mesh structure 190 has a certain hardness, is not easy to deform, and has pressure resistance, making it more difficult for the fan blades 112 to contact the outside; the mesh structure 190 can be but is not limited to a mesh cover, but is not limited to a metal mesh, a plastic mesh, etc.
