The fatal defect that the bearing point cannot be blown is that not only a drying dead angle which is difficult to eliminate is left, but also the convection heat dissipation efficiency of the contact part is greatly attenuated due to the blocking of air flow, so that the heat accumulation is extremely easy to be locally initiated, and the burnt and scrapped appearance of fine artworks such as straw plaited products is directly caused. Based on this, the above-mentioned prior art has room for improvement.
