[0002] In order to solve the problem of the single function of existing mattresses, chair cushions, etc., the applicant provided a multifunctional intelligent mat in a prior application. An air-driven fan is provided inside the multifunctional intelligent mat. When the air-driven fan operates, the outside air flow enters through the air flow holes provided on the side surface of the intelligent mat, and then the absorbed outside air flow is transmitted to the upper human body through the air outlet of the air-driven fan.

[0084] In this embodiment, the comfort buffer layer 1 is provided with a comfort buffer body 1-1. The comfort buffer body 1-1 is a hollow structure, and the front, back, and side of the comfort buffer body 1-1 are all breathable structures.

[0085] Specifically, as Figure 2 shown, the hollow cavity of the comfort buffer body 1-1 is divided into several hollow cells distributed in an array, and air flow is allowed between adjacent hollow cells. The comfort buffer body 1-1 is made of a material with certain softness and resilience, so as to achieve the effect of comfort buffering.

[0086] In this embodiment, as Figure 3 shown, the function layer 2 is composed of a wrapping layer 2-1, a buffer air flow circulation layer 2-2, and a heating layer 2-3.
