The fixing layer 12 is fixed to the inside of the base 2 by using a sewing process, and specifically, the sewing process is used to fix the four end edges of the fixing layer to the front of the base 2, so that the first support structure 11, the air moving assembly 14 and the control assembly 13 are wrapped and fixed in the inside of the base 2 by the fixing layer 12, and finally the fixing layer 12, the first support structure 11, the air moving assembly 14, the control assembly 13 and the base 2 form an integral whole.

Each air duct through clamping position 110 is provided with an air flow pipe 113, which realizes the exchange of air flow between the wind assembly 14 and the outside of the base 2.
[0057] It should be noted that when the control assembly 13, the wind assembly 14 and the first support structure 11 are arranged in the base 2, the front surfaces of the control assembly 13, the wind assembly 14 and the first support structure 11 are in the same horizontal plane as the front surface of the base 2, so that the entire front surface of the wind layer 1 does not have a concave-convex feeling.

The air port in the side face of the air moving device 14 is attached to the air outlet 41 in the side wall of the second protective cover 4, and the air port exchanges air with the outside through the air duct groove 16.
[0060] The working principle of the multifunctional pad in the utility model is as follows:
[0061] Fan-driven (exhaust) cooling function: The fan installed in the fan layer 1 of the multi-functional pad operates to provide ventilation. The heat (i.e., hot airflow) generated by the human body above the front of the fan is absorbed through the wrapping layer 6 on the multi-functional pad at the front air inlet of the fan. The airflow then flows through the vents in the front of the wrapping layer 6 into the interior of the wrapping layer 6, and then through the wrapping layer 6 into the interior of the functional layer 5 (i.e., to the second support buffer 51 in the functional layer 5). From there, the airflow flows to the heating layer 54, then through the guide holes in the heating layer 54 to the airflow guide layer 52, and then through the first guide hole 521 in the airflow guide layer 52 to the second support buffer 51. Finally, the airflow flows to the bottom of the second support buffer 51, i.e., the functional layer. The heat absorbed by the human body is blown out through the bottom of the functional layer 5 to the second exhaust port 121 set on the front of the fixed layer in the wind-driven layer 1. Then, it flows through the second exhaust port 121 to the exhaust port 41 on the front of the second protective cover 4 in the wind-driven layer 1. Through the exhaust port 41, it flows to the air inlet of the wind-driven device, i.e. the wind-driven fan, set inside the second protective cover 4. The heat absorbed by the human body is blown out through the air duct groove or airflow pipe set in the wind-driven layer 1 to the first exhaust port 22 set on the sides of the base 2 in the wind-driven layer 1. Through the first exhaust port 22, it is blown out to the outside of the sides of the wind-driven layer 1, i.e. the outside of the sides of the multi-functional pad, so as to ultimately achieve the wind-driven (exhaust) cooling effect experience for the human body located above the front of the multi-functional pad.
[0062] Heating Function: The heating layer 54 within the functional layer 5 of the multi-functional pad heats the material. The heat generated by the heating layer 54 flows into the support buffer 51. Since the support buffer 51 has an airflow-through structure, external airflow from all sides enters the support buffer 51, thus achieving the heating function. It should be noted that the side vents of the fan can also be used for exhaust, while the front vents blow air, transferring the heat generated by the heating layer 54 to the second support buffer 51. Due to the breathable design of the second support buffer 51, the second support buffer... External airflow enters the support buffer body 51 from all sides of the body 51, causing the heating airflow inside the second support buffer body 51 to form a flowing hot airflow. This allows the hot airflow to flow freely throughout the entire internal space of the second support buffer body 51, making the second support buffer body 51 a flowing hot airflow buffer. The hot airflow then flows through the second support buffer body 51 to the wrapping layer 6 on the front of the multifunctional pad, and finally flows through the vents in the wrapping layer 6 to the human body located above the front of the wrapping layer 6, thus achieving the heating effect of the multifunctional pad for the human body.
[0063] In order to further optimize the above technical solutions, the multifunctional cushion in the utility model can be provided with two or more, and each part is spliced, as shown in Figures 14-15 When the multifunctional cushion and the back cushion are composed of two multifunctional cushions, the wrapping layer 6, the functional layer 5 and the air moving layer 1 are provided with two groups, one group is the back cushion, and the other group is the seat cushion, and the arrangement between the adjacent multifunctional cushions is as follows:
