First trapezoidal support skeletons 201 are equidistantly arranged in the support surface layer 2. Small honeycomb-shaped filter holes 401 and large honeycomb-shaped filter holes 402 are equidistantly arranged in the titanium fiber filter layer 4.

Then, the titanium fiber filter layer 4 adopts a honeycomb channel structure of small honeycomb-shaped pores 401 and large honeycomb-shaped pores 402, with a diameter set to 130um - 150um and a filtering efficiency of 99%. By adopting the special pore diameters of the small honeycomb-shaped pores 401 and the large honeycomb-shaped pores 402, the filtering efficiency is improved.

The first trapezoidal support framework 201 and the second trapezoidal support framework 901 both use titanium fiber materials. By using the first trapezoidal support framework 201 and the second trapezoidal support framework 901 respectively, the structural strength of the support surface layer 2 and the protective coating 9 is increased, preventing damage from occurring on the upper and lower sides and both sides. Moreover, by using fiber materials, the product is more flexible, has high strength, and is light in weight.
