The outer layer 220 is spaced apart from the inner layer 210 on a side away from the central axis of the housing 100, and the outer layer 220 surrounds the inner layer 210. Two cover plate layers 230 are respectively arranged at two opposite ends of the grid body 200 along the axial direction of the shell 100, wherein one cover plate layer 230 is connected with the outer periphery of the upper end of the inner layer 210 and the outer periphery of the upper end of the outer layer 220, and the other cover plate layer 230 is connected with the outer periphery of the lower end of the inner layer 210 and the outer periphery of the lower end of the outer layer 220, so that the outer layer 220, the inner layer 210 and the two cover plate layers 230 jointly enclose and form the oil storage cavity 201.

In this manner, the atomization medium is not likely to leak from the end of the mesh body 200 near the nozzle 120 when the electronic atomizer is inverted or in an accident situation.

The material of the mesh body 200 may be PP, PE, PET, PA, PTFE or other similar compositions, all of which have heat-resistant characteristics and can be selected for use as desired.

Further, in the present embodiment, the oil sucking member 430 has two oil sucking members 430, and the two oil sucking members 430 are respectively connected to opposite ends of the oil guiding member 410 in its own axial direction such that each oil sucking member 430 is located between the oil storing member and the oil guiding member 410. Each oil sucking member 430 has a stepped cylindrical structure in which one end having a smaller diameter is connected to one end of the oil guiding member 410.

Thus, the atomized medium can be introduced into the oil guiding member 410 more rapidly through the oil suction groove 431, and the oil guiding capability of the oil sucking member 430 is further enhanced.

The oil absorbing member 430 is made of the same material as the oil storage member, and is also made of PP, PE, PET, PA, PTFE or other similar composition, which is not limited specifically.

It should be noted that the structure of the atomizing core 400 is not limited to the structure mentioned in the above embodiment, and the oil sucking member 430 may not be provided, but obviously, the oil guiding effect of the atomizing core 400 is better after the oil sucking member 430 is provided. For example, the oil guiding member 410 may also be a cylindrical hollow structure, the heating member 420 is wound around the inner wall of the oil guiding member 410 and sintered with the oil guiding member 410 into a whole in the central tube 300 coaxially disposed, the oil absorbing member 430 is also a cylindrical hollow structure and sleeved on the outer circumferential surface of the oil guiding member 410, the atomized medium directly permeates to the oil absorbing member 430 through the oil through hole formed in the central tube 300, and the atomized medium is introduced into the oil guiding member 410 by the oil absorbing member 430, which is not limited herein.
