Negative-pressure suction type electronic cigarette atomizing core structure

Abstract

The invention discloses a negative-pressure suction type electronic cigarette atomizing core structure, which comprises an atomizing core shell, electric heating wires and liquid guide fiber cotton. The heating wires are arranged in the atomizing core shell; the liquid guide fiber cotton is arranged on the peripheries of the heating wires; liquid inlet holes are formed in the atomizing core shell; and the ends of the liquid guide fiber cotton are arranged on the locations of the liquid inlet holes. On the locations of the liquid inlet holes, the atomizing core shell protrudes inwards and is provided with a throat part of an annular strip; and the atomizing core on the locations of the liquid inlet holes is less than other parts of the atomizing core in inner diameter. The electric heating wires are arranged in the form of spirals; the liquid guide fiber cotton is designed as a rope-shaped structure and is arranged in the spirals; and the sectional area of the liquid guide fiber cotton is more than the area of the liquid inlet holes of the atomizing core shell. Each liquid inlet hole is a single round hole, a sieve-shaped liquid inlet hole which is formed by combining a plurality of holes or a grid-shaped liquid inlet hole which is formed by combining a plurality of strip-shaped holes. The structure of the atomizing core is a negative-pressure area which is generated on the basis of the venturi principle which is commonly used in physics; therefore, the atomizing core is beneficial for preventing liquid leakage and insufficient liquid supply.

Description

technical field [0001] The invention relates to a product structure in the field of daily life, in particular to a structure of an atomizing core in an electronic cigarette atomizer. Background technique [0002] With the development of science and technology and society, people gradually realize the harm of smoking tobacco to the body, and gradually restrict or even ban tobacco smoking on certain occasions, so as not to affect people's health and the surrounding environment. However, since most smokers are already addicted to smoking, it is not easy to completely quit smoking, so there is an electronic cigarette product, which is currently popular in the market to atomize liquid containing nicotine by electric heating. Smoking this mist satisfies the needs of smokers, and has a tendency to replace tobacco to some extent. [0003] The current electronic cigarette products on the market use a heating wire to heat a liquid e-cigarette liquid, so that after the e-cigarette liq...

Problems solved by technology

However, when the opening is relatively large, when the adsorption reaches a saturated state, the liquid-guiding fiber cotton 3 will seep out the e-cigarette liquid, and the exuded e-cigarette liquid will drip and gather, and will flow out from the air inlet 7 to a certain extent, while Generally, the air intake hole 7 cannot be closed, because after it is closed, it cannot enter the air, and therefore cannot smoke.

The impact from the outside is that the e-cigarette liquid will flow out from the air intake hole, affecting the cleanliness and feeling

[0006] Second, because the electronic cigarette relies on the electric heating wire to atomize the liquid, when the atomization is turned on for a long time, even the larger liquid inlet hole can not meet the demand of the liquid, resulting in insufficient supply of the liquid. On the other hand, when the supply of e-cigarette liquid is not available, the phenomenon of dry burning of the heating wire and the liquid-conducting fiber cotton will occur

Not only greatly increases the temperature of the sucked mist, but it is easy to scald the mouth and make the smoker feel unacceptable

At the same time, due to the phenomenon of dry burning, the danger of smoking electronic cigarettes is greatly increased, and the service life of the atomizing core is also greatly reduced.
