First claim
Opening claim text (preview).
What is claimed is: 1. An electromagnetic heating smoking paraphernalia capable of evenly heating tobacco particles, comprising: a tobacco particle heating tank, wherein the tobacco particle heating tank comprises a metal inductive cylinder and a tight coil wrapping the metal inductive cylinder at a distance, a space between the metal inductive cylinder and the tight coil is a tobacco particle holding cavity; a first end of the tobacco particle holding cavity is provided with an upper end wall, the upper end wall is provided with an upper end wall vent hole, a second end of the tobacco particle holding cavity is provided with a lower end wall, the lower end wall is provided with a lower end wall vent hole; the tight coil means that adjacent turns of a coil are tightly placed close to each other in a longitudinal axial direction without a gap; an inner wall of the metal inductive cylinder is provided with an inner wall vent hole. 2. The electromagnetic heating smoking paraphernalia capable of evenly heating tobacco particles according to claim 1 , further comprising an e-juice atomizer located upstream of the tobacco particle heating tank, the e-juice atomizer is interconnected to the tobacco particle holding cavity through the lower end wall vent hole and the inner wall vent hole. 3. The electromagnetic heating smoking paraphernalia capable of evenly heating tobacco particles according to claim 1 , wherein a cigarette filter is provided in a downstream of the tobacco particle heating tank, the cigarette filter and the tobacco particle heating tank are interconnected to each other through the upper end wall vent hole for airflow to pass through. 4. The electromagnetic heating smoking paraphernalia capable of evenly heating tobacco particles according to claim 1 , further comprising tobacco particles contained in the tobacco particle holding cavity, wherein the tobacco particles comprise tobacco shreds, tobacco grains or tobacco piece scraps. 5. The electromagnetic heating smoking paraphernalia capable of evenly heating tobacco particles according to claim 1 , wherein a cigarette paper is not used.
