1. An electronic cigarette atomizing core comprising:
an outer sleeve and an inner sleeve which are sleeved on each other, wherein:
a side wall of the outer sleeve is provided with a first e-liquid passing port communicated with an e-liquid tank,
two ends of e-liquid guide cotton are sandwiched between the outer sleeve and the inner sleeve,
an atomization cavity is provided below a bottom of the inner sleeve, characterized in that a side wall of the inner sleeve is provided with a plurality of air inlet grooves penetrating the atomization cavity axially and in a same direction as e-liquid flowing into the atomization cavity,
at least one air inlet groove is communicated with the first e-liquid passing port by means of the e-liquid guide cotton such that a part of air flowing through the at least one air inlet groove directly passes through the e-liquid guide cotton and then passes through the first e-liquid passing port into the e-liquid tank to realize replacement of e-liquid,
e-liquid guide cotton mounting grooves for mounting the e-liquid guide cotton are symmetrically formed on an outer wall of the inner sleeve,
the e-liquid guide cotton mounting grooves are provided with a clamping segment at an upper part for clamping the e-liquid guide cotton and a loosening segment at the lower part,
a depth of the e-liquid guide cotton mounting grooves at the clamping segment is less than that of the e-liquid guide cotton mounting grooves at the loosening segment, and
at least one air inlet groove penetrates the loosening segment.
