Abstract
A smoking paraphernalia cooled by a smoke flow includes the following components: a shell; a smoking cup placed inside the shell, wherein a part of a bottom of the smoking cup is provided with a heating unit socket, a plurality of air inlet holes and a protruded step; a pushing key; a heating unit; and a fixing base. According to the smoking paraphernalia of the present invention, a surface temperature of the shell can be reduced, and tobacco residues can be conveniently cleaned, which prevents smoke from flowing toward an interior of the smoking paraphernalia and prolongs the service life of the smoking paraphernalia.
