The above is a detailed description of the structure of the present invention. Next, the present invention will be further described through the working principle.

First, as shown in FIG. 6 , the e-liquid in the e-liquid tank 201 flows into the cavity 3015 of the ceramic heating wire assembly 301 along the direction of the arrow in FIG. 6 due to gravity until the e-liquid is filled.

As shown in FIG. 7 , since the ceramic heating wire assembly 301 has microporous oil-conducting properties, the e-liquid penetrates into the ceramic medium as indicated by the arrow in FIG. 7 until the oil absorption reaches a saturated state. During this process, the ceramic heating wire assembly 301 simultaneously conducts gas exchange through the micropores of the ceramic medium until the internal and external atmospheric pressures are balanced.

As shown in FIG. 8 , the ceramic heating wire assembly 301 is provided with square gaps 3011 on the left and right sides, and an oil-barrier and breathable layer 3016 is plated on the surface of the square gap 3011 (in this embodiment, the oil-barrier and breathable layer 3016 is Teflon) , through the square gap 3011 to speed up the exchange rate of the internal and external atmospheres to maintain the air pressure balance, and to speed up the penetration of the e-liquid, and to prevent oil leakage from the square gap 3011 through the oil separation and ventilation layer 3016.

As shown in FIG. 9 , the heating wire 3013 of the ceramic heating wire assembly 301 is tightly connected with the electrode 302, and after the electrode 302 is energized with the battery, it generates heat, which drives the ceramic heating wire assembly 301 to heat. After the e-liquid reaches the vaporization temperature, it is atomized and smoke is generated.

As shown in FIG. 10 , the arrow in FIG. 10 is the smoke outlet air flow channel. After the ceramic heating wire assembly 301 heats and vaporizes the smoke oil to form smoke, the smoke will go out through the air passage. This process is the process of smoking from the suction nozzle 1 .

As shown in FIG. 11 , the upper arrow A in FIG. 11 represents air, and the lower arrow B represents e-liquid. In the process of each smoking, the amount of e-liquid will decrease accordingly. Since the volume V in the e-juice tank is constant, the volume V of the e-juice decreases and the air volume V increases. According to the formula: P1V1=P2V2, when the gas volume V of fixed mass increases, P will decrease. Therefore, at this time, the air pressure in the e-juice tank is lower than the external atmospheric pressure, and the outside air enters the e-liquid tank through the micro-holes in the ceramic heating wire due to the pressure difference to ensure the air pressure balance.

As shown in Figure 12, the upper arrow C in Figure 12 represents the air pressure in the e-juice tank, the middle arrow D represents the seal, and the lower arrow E represents the outside atmospheric pressure. On this basis, the entire process of ensuring air pressure balance shown in Figure 11 is a microscopic process. During the smoking process, the interaction between the internal air pressure of the finished atomizer and the external air pressure is a continuous process, but when the smoke When the oil is consumed, due to the increase of the air volume V in the e-liquid tank 201, the atmospheric pressure outside the ceramic medium is greater than the internal air pressure. At this time, the e-liquid in the e-liquid tank 201 cannot penetrate into the ceramic due to the atmospheric pressure. When the fuel supply speed is insufficient, the It will cause the heating wire 3013 to dry to form a paste core, and the present invention has a square notch 3011 on the left and right of the ceramic heating wire assembly 301, and an oil-separating and breathable layer 3016 plated on the surface of the square notch 3011. The internal and external air pressure is balanced, thereby speeding up the penetration rate of e-liquid, so that the heating wire 3013 is not prone to the problem of paste core.

To sum up, the present invention solves the problem of paste core by cutting a small square gap on the left and right sides of the ceramic heating wire assembly to increase the area of air exchange between inside and outside of the ceramic medium, speed up the speed of air exchange between inside and outside, and speed up the penetration rate of e-liquid; The oil separation and ventilation layer is set at the gap to achieve the purpose of passing air but not oil, and effectively solve the problem of oil leakage.

To sum up, although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the scope defined by the claims.
