[0013] 3. The guiding and sealing structures, the e-liquid storage structure, and the air passages of the atomizer are made of glass, which is environmentally friendly and healthy. FIG. 1 is an exploded view of an atomizer according to one embodiment of the disclosure; FIG. 2 is a perspective view of an atomizer according to one embodiment of the disclosure; FIG. 3 is a sectional view of an atomizer according to one embodiment of the disclosure; and FIG. 4 shows an air flow direction of an atomizer according to one embodiment of the disclosure.

[0014] To further illustrate, embodiments detailing an atomizer and an electronic cigarette comprising the same are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

[0015] As shown in FIGS. 1-3, an atomizer comprises an outer glass tube 1, an inner glass tube 1-1, a fixing sleeve 2, a first silica ring 3, a heating element 4, a decorative ring 5, a leak-proof ring 6, a second silica ring 7, a fixed ring 8, a base 9, an insulation ring 10, and an electrode 11. The inner wall of the outer glass tube 1 and the outer wall of the inner glass tube 1-1 form a cavity for accommodating e-liquid. The inner glass tube 1-1 functions as a duct for discharging air and vapor. The first silica ring 3 is hollow and disposed on the heating element 4 to seal the bottom end of the inner glass tube 1-1. The fixing sleeve 2 comprises a heating chamber and the heating element 4 is disposed in the heating chamber. One end of the fixing sleeve 2 comprises an e-liquid inlet. One end of the e-liquid inlet communicates with the cavity for accommodating e-liquid, the other end faces the heating element 4. The leak-proof ring 6 is disposed in the heating chamber of the fixing sleeve. The upper end of the leak-proof ring 6 abuts against the heating element 4 to fix and support the heating element 4. The outer peripheral wall of the leak-proof ring 6 abuts against the inner wall of the heating chamber to prevent the vapor and e-liquid exuded from the outer peripheral wall of the heating element from flowing out along the peripheral wall of the heating chamber. The fixing sleeve 2 is fixed in the bottom opening of the outer glass tube 1 and the bottom end of the inner glass tube 1-1 is in contact with the first silica ring 3. The second silica ring 7 is disposed in the base 9 for preventing the leakage of air and e-liquid. The fixed ring 8 is screwed on the base 9 to support the outer glass tube 1. The decorative ring 5 is disposed around the fixed ring 8 to fix the outer glass tube 1. The lower end of the outer glass tube 1 is disposed in the decorative ring 5 and the bottom end of the outer glass tube 1 is supported by the fixed ring 8. The fixing sleeve 2 is disposed in the top opening of the base 9. The insulation ring 10 is disposed in the bottom opening of the base 9 to separate the positive and negative pins of the heating element 4 to prevent short circuit. The electrode 11 is disposed in the insulation ring 10 to fix the positive pin of the heating element 4 for electric conduction.

[0016] FIG. 4 shows the flow direction of the e-liquid and air of the atomizer. Specifically, the e-liquid flows into the heating element 4 via the opening of the fixing sleeve 2 and is atomized by the heating element. The air flows into the base 9 via the air inlet on the outer wall of the bottom part of the base, flows through the hollow center of the second silica ring 7 and drives the vapor produced by the heating element 4 to flow through the first silica ring 3 and enter the inner glass tube 1-1, and then flows to the outer glass tube 1 for inhaling by a user.

[0017] Optionally, the base 9 comprises an air regulation ring provided with the air inlet. The opening size of the air inlet is adjustable by rotating the air regulation ring thereby adjusting the amount of the produced vapor. The material of the inner and outer glass tubes can be replaced by ceramics, quartz, mica, jade, and the like. The resistance of the heating element is arbitrary. The heating element is a metal or a metal alloy. The heating element 4 can be in an arbitrary shape, and the periphery thereof can be wrapped with cotton, and the number of the air inlet on the base 9 is more than one in any shape.
