Abstract

The present disclosure discloses an electronic cigarette including a main body and an atomizer. The atomizer is adapted for being detachably mounted to a cartridge. The cartridge includes a containing cavity for storing e-liquid and a sealing film for sealing the containing cavity. The atomizer is provided with a first guide tube, a second guide tube and a heating tube connecting the first guide tube and the second guide tube. The atomizer includes a first end portion and a second end portion at a front end of the atomizer in order to pierce the sealing film. With this configuration, when the cartridge is used up, only a new cartridge needs to be replaced and the atomizer does not need to be scrapped together for saving cost.

the atomizer comprises a first guide tube, a second guide tube and a heating tube, the heating tube is in communication with the first guide tube and the second guide tube; the first guide tube, the second guide tube and the heating tube jointly form an internal channel to store the e-liquid when the e-liquid flows out of the cartridge; the first guide tube and the second guide tube are configured to gather the e-liquid and guide the e-liquid flowing into an internal tube cavity of the heating tube; wherein
the heating tube is adapted to heat and atomize the e-liquid stored in the internal tube cavity, and the heating tube comprises at least one gas outlet through which the e-liquid after atomization flows out of the heating tube; and wherein
the atomizer comprises a first end portion and a second end portion, the first end portion and the second end portion are located at a front end of the atomizer, and the first end portion and the second end portion are adapted to pierce the sealing film so that the e-liquid stored in the cartridge is capable of flowing into the first guide tube and the second guide tube.

2. The electronic cigarette according to claim 1 , wherein the atomizer comprises a first guide portion and a second guide portion, the first guide portion is mounted to the first guide tube and located at a rear end of the first end portion, the second guide portion is mounted to the second guide tube and located at a rear end of the second end portion; and wherein the first guide portion and the second guide portion are adapted to guide the first guide tube and the second guide tube to be inserted into the e-liquid.

3. The electronic cigarette according to claim 2 , wherein the first guide portion and the second guide portion are tapered shapes.

4. The electronic cigarette according to claim 3 , wherein the first end portion is located at a front end of the first guide tube, and the second end portion is located at a front end of the second guide tube.

5. The electronic cigarette according to claim 1 , wherein the cartridge and the main body comprise positioning structures mated with each other.

6. The electronic cigarette according to claim 5 , wherein the positioning structures comprise a first protrusion and a first recess, the first protrusion is formed on the cartridge, the first recess is formed on the main body, and the first protrusion is received in the first recess.

7. The electronic cigarette according to claim 5 , wherein the positioning structures comprise a first recess and a first protrusion, the first recess is formed on the cartridge, the first protrusion is formed on the main body, and the first protrusion is received in the first recess.

8. The electronic cigarette according to claim 1 , wherein the cartridge comprises an atomizing gas suction port and a suction tube, the suction tube is in communication with the atomizing gas suction port; and wherein
the atomizer comprises an air inlet corresponding to the heating tube, and the air inlet is in communication with the suction tube.

9. The electronic cigarette according to claim 8 , wherein the suction tube protrudes beyond the sealing film, the atomizer comprises a through hole, and the through hole partially accommodates the suction tube.

10. The electronic cigarette according to claim 2 , wherein the atomizer comprises a housing, the housing is formed on the first guide tube and the second guide tube; wherein the first guide portion and the second guide portion are formed on the housing; wherein the atomizer further comprises a first sealing member and a second sealing member, the first sealing member is sleeved on a rear end of the first guide portion, and the second sealing member is sleeved on a rear end of the second guide portion.

11. The electronic cigarette according to claim 10 , wherein the first sealing member and the second sealing member are sandwiched between an upper surface of the casing and the sealing film.

12. The electronic cigarette according to claim 1 , wherein the heating tube comprises a heating element, a positive conductive sheet and a negative conductive sheet; and wherein the positive conductive sheet and the negative conductive sheet are connected to the heating element.

13. The electronic cigarette according to claim 12 , wherein the heating element is a heating wire, a heating sleeve or a heating sheet.

14. The electronic cigarette according to claim 12 , wherein the main body comprises an electronic cigarette device, the electronic cigarette device comprises a power source connected to the positive conductive sheet and the negative conductive sheet.

15. An electronic cigarette, comprising:
a main body;
an atomizer, mounted to the main body; and
a cartridge, detachably mounted to the atomizer, the cartridge comprising a containing cavity, a sealing film, and an atomizing gas suction port, the containing cavity being used for storing e-liquid, the sealing film being used for sealing the containing cavity; wherein
