The above is a detailed description of the structure of the present invention, and the following is a further description of the present invention through the working principle.

First, as shown in fig. 6, the tobacco tar in the tobacco tar bin 201 flows into the inner cavity 3015 of the ceramic heating wire assembly 301 along the arrow direction in fig. 6 due to gravity until the tobacco tar is filled therein.

As shown in fig. 7, the ceramic heating wire assembly 301, due to the microporous oil-guiding property of the ceramic, the soot permeates into the ceramic medium as shown by the arrow in fig. 7 until the soot is saturated. In the process, the ceramic heating wire assembly 301 simultaneously generates gas exchange through the ceramic medium micropores until the internal and external atmospheric pressures are balanced.

As shown in fig. 8, the ceramic heater strip assembly 301 has square notches 3011 on the left and right sides, and an oil-separation and air-permeable layer 3016 (in this embodiment, the oil-separation and air-permeable layer 3016 is made of teflon) is coated on the surface of the square notch 3011, so that the air pressure balance is maintained by increasing the exchange speed between the inside and outside air through the square notch 3011, and the permeation of smoke and oil is increased, and oil leakage from the square notch 3011 is prevented by the oil-separation and air-permeable layer 3016.

As shown in fig. 9, the heating wire 3013 of the ceramic heating wire assembly 301 is tightly fitted and conducted with the electrode 302, and after the electrode 302 is electrified with the battery, it generates heat to drive the ceramic heating wire assembly 301 to heat, and after the temperature rises, the tobacco tar introduced into the ceramic core reaches the gasification temperature and then is atomized to generate smoke.

As shown in fig. 10, the arrows in fig. 10 are smoke outlet airflow channels, and after the ceramic heating wire assembly 301 heats the gasified tobacco tar to form smoke, the smoke is discharged through the airflow channels, and the smoke is smoked from the mouthpiece 1.

As shown in fig. 11, the upper arrows a in fig. 11 represent air, and the lower arrows B represent tobacco tar. During each smoking, the amount of tobacco tar is reduced. Because the volume V in the tobacco tar bin is unchanged, the volume V of the tobacco tar is reduced, and the volume V of the air is increased. According to the formula: P1V1 ═ P2V2, and P decreases as the fixed mass gas volume V increases. Therefore, the air pressure in the tobacco tar bin is lower than the external atmospheric pressure, and the external air enters the tobacco tar bin through the micropores in the ceramic heating wires due to the air pressure difference so as to ensure the air pressure balance.

As shown in fig. 12, the upper arrow C in fig. 12 indicates the air pressure in the tobacco tar compartment, the middle arrow D indicates the sealing position, and the lower arrow E indicates the outside air pressure. Under this basis, the balanced whole process of assurance atmospheric pressure that fig. 11 shows is the microtechnique, at the in-process of smoking, the inside atmospheric pressure of atomizer finished product and external atmospheric pressure are alternately balanced and are being carried on the in-process that lasts constantly, but when the tobacco tar consumed, because of the increase of air volume V in the tobacco tar storehouse 201, the atmospheric pressure outside the ceramic medium is greater than inside atmospheric pressure, the tobacco tar is because of atmospheric pressure inefficiently ceramic infiltration in the tobacco tar storehouse 201 this moment, when fuel feeding speed is not enough, will cause heating wire 3013 dry combustion to form and paste the core, and the utility model discloses an it has square notch 3011 to open about ceramic heating wire subassembly 301 to at the ventilative layer 3016 of oil removal that square notch 3011 surface plated, accelerated the atmosphere exchange speed, guaranteed that inside and outside atmospheric pressure is balanced, thereby accelerated the tobacco tar infiltration speed, make heating wire 3013 be difficult to appear pasting the core problem.

In summary, the utility model increases the inner and outer air exchange area of the ceramic medium by cutting a square small notch on the left and right of the ceramic electric heating wire assembly, accelerates the inner and outer air exchange speed, accelerates the smoke penetration speed, thereby solving the core pasting problem; the purpose of passing air but not passing oil is achieved by arranging the oil-separating and ventilating layer at the notch, and the problem of oil leakage is effectively solved.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.
