BACKGROUND
1. Technical Field
[0001] The present invention relates to electronic cigarettes, and particularly to an atomizing
device and an electronic cigarette having the atomizing device.
2. Description of Related Art
[0002] Atomizing devices are key components of electronic cigarettes. A typical atomizing
device includes a reservoir cotton, a tobacco solution reserved in the reservoir cotton,
and a heating assembly for heating and atomizing the tobacco solution. Then the atomized
tobacco solution can be sucked by a user of the electronic cigarette.
[0003] However, as the reservoir cotton is immersed by the tobacco solution, the reservoir
cotton may be smelly after a long time immersion, thereby the taste of the tobacco
solution may be changed accordingly.
[0004] What is needed, therefore, is an atomizing device and an electronic cigarette which
can overcome the above shortcomings.

DETAILED DESCRIPTION
[0006] Embodiments of the present electronic cigarette will now be described in detail below
and with references to the drawings.
[0007] Referring to FIGs. 1 to 3, an atomizing device 100 of an electronic cigarette in
accordance with a first embodiment is provided. The atomizing device 100 includes
an atomizing sleeve 1, an air pipe 5, a heating assembly 4 fixed on the air pipe 5,
a metallic ring 7 and a nozzle 3 located respectively at two ends of the air pipe
5, a heating assembly fixing base 8, and a sealing cover 2. The heating assembly fixing
base 8 is fixed on the metallic ring 7. The sealing cover 2, air pipe 5, metallic
ring 7, and heating assembly fixing base 8 are received in the atomizing sleeve 1.
The sealing cover 2, air pipe 5, heating assembly fixing base 8, and metallic ring
7 cooperatively define a sealed tobacco solution reserving space 11 without a reservoir
cotton received therein.
[0008] In addition, an electrode ring 9 is fixed in the metallic ring 7, and an insulating
ring 10 is located between the metallic ring 7 and the electrode ring 9. The metallic
ring 7 and the electrode ring 9 are respectively connected to a positive end and a
negative end of a power source.
[0009] The heating assembly 4 includes a glass fiber core 41 and a heating coil 42 winding
around the glass fiber core 41. Two ends of the heating coil 42 are connected to the
electrode ring 9 and the metallic ring 7, respectively. The glass fiber core 41 can
absorb the tobacco solution reserved in the tobacco solution reserving space 11, and
the heating coil 42 can heat the tobacco solution absorbed by the glass fiber core
41, thereby atomizing the tobacco solution. Therefore, the atomizing device 100 work
properly without a conventional reservoir cotton, and the taste of the tobacco solution
cannot be changed.
[0010] Referring to FIGs. 4 and 5, the sealing cover 2 has an air through hole 22 and a
connecting groove 23. The connecting groove 23 surrounds the through hole 22. The
air pipe 5 is inserted in the connecting groove 23 and is in communication with the
through hole 22. The sealing cover 2 is arranged adjacent to the nozzle 3. The sealing
cover 2 is made of a flexible material, and has a tobacco solution filling hole 21
configured for filling the tobacco solution into the tobacco solution reserving space
11 between the atomizing sleeve 1 and the air pipe 5. The tobacco solution filling
hole 21 is a blind hole. A needle can be used to fill the tobacco solution into the
tobacco solution reserving space 11 during filling the tobacco solution. As the tobacco
solution reserving space 11 is sealed, a negative pressure is formed in the tobacco
solution reserving space 11 after the tobacco solution is used, thereby the tobacco
solution would not leak out through the metallic ring 7 and the electrode ring 9 even
when the atomizing device 100 stands upwards.
[0011] Referring to FIG. 6, the heating assembly fixing base 8 includes a central through
hole 84, a first sidewall through hole 82, and a second sidewall through hole 83.
Axes of the central through hole 84, first sidewall through hole 82, and second sidewall
through hole 83 are parallel with each other. Two ends of the heating coil 42 respectively
extend through the first sidewall through hole 82 and the second sidewall through
hole 83, and respectively bend at an outer wall of the heating assembly fixing base
8 and an inner wall of the central through hole 84. The electrode ring 9 is positioned
inside the central through hole 84.
[0012] Referring to FIG.2 and FIG. 6, the heating assembly fixing base 8 further has an
inserting hole 81 in communication with the central through hole 84. The air pipe
5 is inserted in the inserting hole 81.
[0013] Referring to FIG. 1 again, a tobacco solution obstructing ring 6 is arranged on the
air pipe 5 inside the atomizing sleeve 1. The tobacco solution obstructing ring 6
is arranged above the heating assembly 4. Referring to FIG. 7, the tobacco solution
obstructing ring 6 includes a first ring 63 and a second ring 61 in communication
with the first ring 63. An inner diameter of the second ring 61 is greater than that
of the first ring 63. In the present embodiment, the second ring 61 is in contact
with the heating assembly 4. An outer wall of the second ring 61 has a cutout surface
62 facing toward the atomizing sleeve 1, and the cutout surface 62 is configured for
controlling a rate of flow of the tobacco solution.
[0014] In the present embodiment, each of the tobacco solution obstructing ring 6, the sealing
cover 2, the nozzle 3, and the heating assembly fixing base 8 is made of a flexible
material. The flexible material can be silicon or plastic material.
[0015] Referring to FIG.8, an atomizing device 200 in accordance with a second embodiment
is provided. The atomizing device 200 is essentially similar to the atomizing device
100. In the present embodiment, the atomizing sleeve 1 has a tobacco solution obstructing
structure 16 integrally formed thereon to ......, so that the tobacco solution obstructing
ring 6 is not needed. The tobacco solution obstructing structure 16 has a through
hole surrounding the air pipe 5, and an inner wall of the through hole has a cutout
surface 17 facing toward the air pipe 5.
[0016] Referring to FIG. 9, an electronic cigarette 400 in accordance with a third embodiment
is provided. The electronic cigarette 400 includes an atomizing device 100 (200) and
a battery assembly 300 connected to the atomizing device 100(200). The battery assembly
300 has a chargeable battery.
