[0053] The present application will be further described below with reference to the accompanying drawings:

The heating element generates heat to atomize the tobacco oil on the porous hard oil guide block 30, and the atomized aerosol is discharged through the atomization channel 23 and finally inhaled by the user. In some embodiments, the porous hard oil guide block 30 is made of glass, ceramic, mica, or quartz, and has multiple micropores therein. Its porous structure provides excellent oil absorption.

The end of the exhaust groove 22 away from the oil hole 24 is connected to the outside atmosphere through the atomization channel 23, thereby balancing the air pressure inside and outside the oil storage chamber 25, preventing the pressure difference inside and outside the oil storage chamber 25 from affecting the smoothness of its oil supply. In some embodiments, the exhaust groove 22 can be connected to the oil hole 24, such as Figure 4 As shown, in some other embodiments, the exhaust groove 22 may not be connected to the oil hole 24, and whether the two are connected to each other does not affect the realization of their functions.

[0059] See also Figure 5In some embodiments, the atomizer core 20 further includes a fixing seat 40 for fixing the porous hard oil guide block 30, the fixing seat 40 includes a support 41 and an abutment 42, the porous hard oil guide block 30 is installed on the support 41, one end of the abutment 42 is connected to the support 41, one side of the abutment 42 faces the inner wall of the atomizer tube 21, and the other side of the abutment 42 faces the porous hard oil guide block 30, and the atomization channel 23 is formed between the abutment 42 and the porous hard oil guide block 30, and a through hole 411 is provided at a position corresponding to the atomization channel 23; the support 41 is used to support the porous hard oil guide block 30, and the abutment 42 and the atomizer tube 21 jointly limit the radial movement of the porous hard oil guide block 30 along the atomizer tube 21, thereby ensuring the stability of the atomizer core 20 structure.

[0060] In some embodiments, the abutment portion 42 is provided with an inwardly concave recess 421 on one side of the porous hard oil guide block 30 , and the porous hard oil guide block 30 abuts against the abutment portion 42 and is enclosed with the abutment portion 42 in the recess 421 to form the atomization channel 23 .

[0061] See also Figure 1 、 2 In some embodiments, one side of the porous rigid oil-conducting block 30 is planar, and the other side is adapted to the inner wall of the atomizing tube 21. The heating element is disposed on the planar side of the porous rigid oil-conducting block 30, and is arranged along the direction in which the atomizing channel 23 extends. The planar side of the porous rigid oil-conducting block 30 abuts the abutting portion 42. In this case, the space formed between the recessed portion 421 of the abutting portion 42 and the planar side of the porous rigid oil-conducting block 30 constitutes the atomizing channel 23. The heating element can be embedded in the planar side of the porous rigid oil-conducting block 30 and can be in the form of a mesh, a filament, or the like.
