The utility model discloses a heating piece embedded glass atomizing core, is equipped with a plurality of oil guiding holes that are penetrated from top to bottom in the oil guiding area, a plurality of micro pits are interconnected, the top wall of heating layer installation groove is equipped with the micro groove that is connected with the oil guiding hole and micro pit, the heating atomizing piece is fixed in the heating layer installation groove, a plurality of atomizing holes are arranged in the oil guiding area of the heating atomizing piece, the micro pit, the micro groove and the heating atomizing piece form the
oil storage gap, the leakage prevention piece is fixed on the top of the oil guiding base plate, a plurality of leakage prevention holes are arranged in the oil guiding area of the leakage prevention piece, the
diameter of the leakage prevention hole is smaller than the
diameter of the oil guiding hole, and the
diameter of the leakage prevention hole is 0.01-0.05 mm. The utility model discloses the micro pit, the micro groove and the heating atomizing piece form the
oil storage gap, when the atomizing agent seeps from the oil guiding hole, in addition to seeping into the atomizing hole, it also seeps into the
oil storage gap, so that the heated atomizing agent is increased, thereby increasing the atomizing amount, and the reduction effect is more sufficient, and the atomizing effect is better.
