Smoke cartridge and electronic cigarette

Abstract

The invention relates to a smoke cartridge. The smoke cartridge comprises a smoke cartridge tube provided with a flue and a liquid storage cavity, a sealing body arranged in the smoke cartridge tube and used for sealing the liquid storage cavity, an atomization core arranged in the sealing body and a base fixedly held with the smoke cartridge tube, wherein the sealing body comprises a sealing piece and a sealing piece formed on the sealing piece or arranged on the sealing piece in a sleeving manner; the sealing piece comprises a closed end, an accommodating end formed by extending downwards from the closed end, an oil duct penetrating through the closed end and extending to the accommodating end and an air duct separated from a flow channel; a balance air groove is formed in the transverseouter side of the sealing piece; air gaps communicating with the balance air groove in the vertical direction are formed in the transverse outer side of the sealing piece; and the liquid storage cavity communicates to an atomization cavity or the air duct through the air gaps and the balance air groove. The smoke cartridge can effectively keep air pressure balance in the liquid storage cavity.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a cartridge and an electronic cigarette. Background technique [0002] Patent application No. 201811033876.0 of the People's Republic of China discloses an atomizer and an electronic cigarette, which includes an atomizing core, a first plastic part for assembling the atomizing core, a second plastic part and a sleeve set outside the first plastic part The housing and the cover that is buckled with the housing and covers the second plastic part. A first sealing part is sandwiched between the atomizing core and the first plastic part, and a second sealing part is sandwiched between the periphery of the first plastic part and the housing. The first plastic part is also provided with an air hole, and the housing is provided with an air channel communicating with the air hole, and the air hole and the air channel are butted with each other and a third sealing member is sandwiched...

AI Technical Summary

Problems solved by technology

[0003] The atomizing core includes an oil-absorbing surface connected to the liquid storage chamber and an atomizing surface connected to the air passage. The liquid seepage surface is provided with an oil groove, and the oil groove is formed by a depression from the oil-absorbing surface. The contact between the oil groove and the e-liquid Insufficient surface, when the electronic cigarette is turned upside down, the e-liquid leaves the oil tank, and when it returns to the position for instant suction, it will cause insufficient penetration of the e-liquid into the atomization surface, resulting in insufficient mist or burning problems

At the same time, the liquid storage chamber is in a sealed state. When the e-liquid gradually decreases, it may cause the liquid storage chamber to be in a negative pressure state, and the inverted e-liquid cannot penetrate the atomizing core; or it may be affected by temperature, humidity, air pressure, etc. , Part of the e-liquid vaporization in the liquid storage chamber causes the pressure in the liquid storage chamber to be too high, and eventually the e-liquid will completely penetrate the atomizing core and cause oil leakage
