Definitions

  • the present invention relates to electronic cigarettes, and particularly to an atomizing device and an electronic cigarette having the atomizing device.
  • 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.
  • the reservoir cotton may be smelly after a long time immersion, thereby the taste of the tobacco solution may be changed accordingly.
  • CN 202 456 410 U discloses an atomizing device according to the preamble of claim 1.
  • the present invention provides an atomizing device for an electronic cigarette according to claim 1.
  • an atomizing device 100 for an electronic cigarette in accordance with an embodiment of the present invention 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • an atomizing device 200 is provided.
  • the atomizing device 200 does not form part of the invention but represents background art that is useful for understanding the invention.
  • the atomizing device 200 is essentially similar to the atomizing device 100.
  • the atomizing sleeve 1 has a tobacco solution obstructing structure 16 integrally formed thereon, 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.
  • an electronic cigarette 400 comprising an atomizing device according to the present invention.
  • 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.
