Abstract

The invention relates to an electromagnetic induction coil for magnetic particle uniform heating. The electromagnetic induction coil is composed of 1 to 4 skeleton densely wound coils. The coils are connected to a medium-high frequency power source in series or in parallel. The electromagnetic induction coil can make a medium-high frequency alternating magnetic field completely and directly heat a component to be heated, has a precise heating depth and heating area, and a very good heating effect, and fundamentally solves the low heating efficiency of resistance-type heat conduction achieved by an electric heating sheet, an electric heating coil and the like. By selecting different coil arrangement manners according to actual demands, tobacco materials at different locations can be heated to achieve different cigarette utensil design layouts.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of electronic cigarette production. More specifically, the present invention relates to an electromagnetic induction coil for soaking magnetic particles. [0003] 【Background technique】 [0004] Heat-not-burn tobacco products (also known as low-temperature cigarettes) are composed of a heater and a cigarette. The shredded tobacco of the cigarette is heated by the heating source of the heater. Smokers demand. At present, the heat-not-burn tobacco products sold or launched on the market are mainly divided into three types according to the heating method: electric heating type, carbon heating type and chemical reaction heating type. More specifically, the current heating methods for heating non-burning tobacco products are mainly electric heating, carbon heating, and chemical reaction exothermic heating. Among them, the most widely used and most abundant product is the electric heating type. [0005]...
