The atomizer 10 comprises a hollow tubular-shaped atomizing sleeve 11, an oil-storage cotton 12, a protection tube 13, an atomizing unit 14 and an atomizing seat 15.
The oil-storage cotton 12 is fixed within the atomizing sleeve 11, and is also hollow tubular-shaped and configured to be coaxial with the atomizing sleeve 11.
The protection tube 13 is affixed onto an inner wall of the oil-storage cotton 12, and comprises a heat-resistant layer 130, a first fiberglass tube 131 and a second fiberglass tube 132. Wherein, the heat-resistant layer 130 is affixed onto the inner wall of the oil-storage cotton 12 and coaxial with the oil-storage cotton 12; the heat-resistant layer 130 is made of a material, such heat-resistant cotton cloth, plastic etc., the first fiberglass tube 131 is coaxially configured at an inner side of the heat-resistant layer 130; the second fiberglass tube 132 is affixed to an outer wall of the first fiberglass tube 131 and the inner wall of the heat-resistant layer 130 and located at an end facing to the nozzle cover 20. Therefore, the heat-resistant layer 130, the first fiberglass tube 131 and the second fiberglass tube 132 commonly construct a protective structure having heat-resistance, and anti-crushing functions. Moreover, the second fiberglass tube 132 is totally clamped and fixed between the heat-resistant layer 130 and the first fiberglass tube 131 after being installed, and its one end abuts against the atomizing unit 14, concretely, the first fiberglass tube 131 defines a pair of perforations (not labeled) in a radial direction thereof for the atomizing unit 14 to pass through, in order to facilitate installation, the perforations tend to be relatively big, the end of the second fiberglass tube 132 abutting against the atomizing unit 14 makes the atomizing unit 14 tightly fixed in the perforations, for preventing the atomizing unit 14 from movement.
The atomizing unit 14 is configured within the protection tube 13, and comprises an oil guiding member 140 and a heating wire 141. Wherein, the oil guiding member 140 has its opposite ends to pass through the first fiberglass tube 131 of the protection tube 13 and abut against the oil-storage cotton 12, to absorb smoke oil from the oil-storage cotton 12, and the heating wire 141 is wound around the oil guiding member 140 for heating and atomization.
The atomizing seat 15 is hermetically fixed to an end of a tube constituted by the oil-storage cotton 12 and the protection tube 13 and remote from the nozzle cover, and is made of silicone material.
The nozzle cover 20 is substantially barrel-shaped, and defines a suction hole (not labeled) for user to suck the electronic cigarette.
The hermetic ring 30 defines an concave chamber 31 oriented to the atomizer 10, a thickness of the top wall of the concave chamber 21 is gradually increased from a circumference to a center so that an upper surface of the top wall is a bevel, and plural through holes 32 are circumferentially defined through the top wall. Therefore, the smoke oil is heated up and atomized into vapor in the atomizer 10, the vapor passes through a space constituted by the nozzle cover 20 and the top wall of the concave chamber 31 of the hermetical ring 30 and is partially liquefied to be smoke oil in case of cold, the liquefied smoke oil is gathered on the upper surface of the top wall, and since the upper surface of the top wall is a bevel, the smoke oil flows down along the upper surface to the circumference of the bottom top wall by gravity, and flows out of the space constituted by the nozzle cover 20 and the top wall of the concave chamber 31 of the hermetical ring 30 via the through holes 32, to thereby eliminate the smoke oil residue, and the users would not inhale the smoke oil, and can have an improved taste experience.
The hermetic ring 30 defines a circumferential slot 33 oriented to the nozzle cover 20 and coaxial with the concave chamber 31, and the slot 33 is used for accommodating a side wall of the nozzle cover 20, to thereby hermetically fix the nozzle cover 20. Additionally, during assembly, the hermetic ring 30 and the nozzle cover 20 are assembled together firstly, and then totally installed into the atomizing sleeve 11, to prevent the hermitic ring 30 from slanting if installed afterwards which can cause oil leakage or no ventilation. The slot 33 is circumferentially configured with stripes 34 on an outer surface of its side wall, and the stripes 34 are interferentially and hermetically engaged with the atomizing sleeve 11. Furthermore, the nozzle cover 20 has a stepped outer side, and a step 21 near the suction hole is interferentially engaged with the inner wall of the atomizing sleeve 11, therefore, the atomizing sleeve 11 is dual-sealed by means of the stripes 24 and the step 21, to efficiently prevent the smoke oil in the oil-storage cotton 12 from leakage via the nozzle cover 20.
