1. A core cartridge for electronic cigarette, comprising:
a main housing having a mouth piece portion, an atomizer portion, a connecting portion extended between said mouth piece portion and said atomizer portion, a liquid storage compartment formed in said connecting portion and a an air inlet, said main housing further having an outer boundary wall and a vapor releasing channel extended from said atomizer portion to said connecting portion,
an atomizer supported in said atomizer portion of said main housing, and
a leakage prevention arrangement, which comprises at least one drainage port formed in said main housing, said drainage port communicating said outer boundary wall with said atomizer in such a manner that condensate formed on an inner surface of said outer boundary wall of said main housing is arranged to be guided to flow back to said atomizer through said drainage port,
wherein said leakage preventing arrangement comprises two drainage ports formed in said atomizer portion of said main housing, each of said drainage ports communicating said outer boundary wall of said main housing with said atomizer, wherein when said electronic cigarette stops operating, condensate formed on an inner surface of said outer boundary wall is guided to flow through said drainage ports and eventually back to said atomizer,
wherein said vapor releasing channel has a tapered cross-sectional shape when viewed from the front so that said inner sidewall of said vapor releasing channel is inclinedly extended from said mouth piece portion toward said atomizer portion, said main housing further has a vapor collection cavity formed between an outer sidewall of said vapor releasing channel and said corresponding inner surface of said outer boundary wall of said main housing,
wherein said inner surface of said outer boundary wall is inclined so that a thickness of said vapor collection cavity gradually increased from said mouth piece portion toward said atomizer portion,
wherein said leakage prevention arrangement further comprises a supporting member provided at a lower end portion of said vapor collection cavity, wherein said supporting member has an extension portion extended in said main housing to define said corresponding drainage port as a gap formed between said extension portion and said corresponding inner surface of said outer boundary wall of said main housing.
