The electromagnetic heating assembly adopting the structure has the advantages of high heat energy conversion efficiency, easy heat dissipation and installation space saving; and the electronic cigarette heating assembly has the advantages of simple structure, low cost and convenient assembly and disassembly besides the advantages described above.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to an electromagnetic heating assembly and a smoking appliance using the heating assembly. Background technique [0002] Smoking seriously endangers health. Studies have shown that smoking can induce lung cancer, heart disease, psoriasis and other diseases. Smoking can also affect sexual function, hinder smooth blood circulation, and affect sleep quality. Although people know that smoking is very harmful, but for In pursuit of the thrill of smoking, there are still many people smoking. At present, electronic cigarettes that can replace ordinary cigarettes have appeared. The feeling of smoking electronic cigarettes is the same as that of ordinary cigarettes, but its harm is far less than that of ordinary cigarettes. [0003] In the current electronic cigarette, there are two kinds of heating methods for the atomizer: resistive heating and electromagnetic heating. Among them, the...

Problems solved by technology

[0003] In the current electronic cigarette, there are two kinds of heating methods for the atomizer: resistance heating and electromagnetic heating. Among them, the thermal efficiency of resistance heating is not high, and the atomization effect of e-liquid is relatively poor. At the same time, the atomizer needs to be replaced as a whole after a period of time. components, which is not conducive to environmental protection; therefore, the current atomizer gradually adopts the method of electromagnetic heating

[0004] Coil structures commonly used in electromagnetic heating solutions include hollow circular straight coils and solid planar coils. figure 1 It is a schematic diagram of the moving direction of the magnetic force line using a hollow circular straight coil. The larger the arrow, the stronger the magnetic force, which means faster heating of the metal. Its disadvantage is that it requires a large space, the length of the induction metal cannot exceed the length of the coil, and the area in contact with the waste heat Large, not easy to dissipate heat; figure 2 It is a schematic diagram of the structure of a solid planar coil, which is used by placing an induction metal above the coil for heating. image 3 It is a schematic diagram of the moving direction of the magnetic force line using a solid planar coil. The larger the arrow, the stronger the magnetic force, which means faster heating of the metal. Its disadvantage is that its efficiency is relatively low due to the very large air magnetic resistance. Add ferrite or magnetic cores and other magnetically permeable materials under the solid planar coil to allow the magnetic force lines at the bottom to return smoothly to the top of the solid planar coil to increase efficiency
