Description
Technical Field
The invention relates to a product structure in the field of daily life, in particular to an atomization core in an electronic cigarette atomizer.
Background
With the development of science and technology and society, people gradually recognize that smoking tobacco is harmful to the body, and smoking tobacco is gradually limited or even prohibited in certain occasions, so that the influence on the physical health and the surrounding environment of people is avoided. However, most smokers are addicted to smoking, and can not easily and completely abstain from smoking tobacco, so that an electronic cigarette product appears, it is the current market current that atomizing nicotine-containing liquids with electrical heating meets the needs of the smoker by sucking such mist, and there is a trend to replace tobacco to some extent.
The electronic cigarette products in the market at present are electronic cigarette liquids with one liquid heated by an electric heating wire, so that after the electronic cigarette liquids are atomized, the fog of the electronic cigarette is sucked, and the smoke generated by combustion is not sucked any more, so that solid particles are not sucked any more, but liquid particles are sucked. The liquid particles are produced by the artificial electronic cigarette liquid, the content of various substances can be basically and accurately controlled, and the substances which are the burnt liquid and have the greatest harm to human bodies during combustion can not be produced.
The known electronic cigarette structure generally comprises an electronic cigarette battery, a control circuit and an electronic cigarette atomizing device, wherein the electronic cigarette atomizing device is made into an atomizing chamber. The atomizing core is arranged in the atomizing chamber and consists of a shell and an internal heating wire, the heating wire is wound into a spiral shape, rope-shaped liquid guide cotton is further arranged in the spiral-shaped heating wire, and the liquid guide cotton is communicated with an external liquid storage chamber through a liquid inlet hole formed in the side face of the atomizing core shell, so that the electronic cigarette liquid is guided into the heating wire of the atomizing core for heating and atomizing under the penetration effect of the liquid guide cotton. In order to realize the smoking function, air is introduced from an air inlet arranged at the bottom of the atomizing core shell to cause the flow of air flow to drive atomized fog to be inhaled into a human body. The air flow flows upwards from the lower part of the atomizing core shell to form air flow, and the electric heating wire is connected with an electrode seat through a wire. However, the existing products have the following defects which are difficult to overcome.
Firstly, the inlet port sets up in the atomizing chamber lower part, and the fine setting of drain is in the upper portion of inlet port, and the fine permeation that relies on of drain adsorbs electron tobacco juice through the feed liquor hole that sets up at atomizing core shell, in order to furthest adsorb electron tobacco juice, needs this feed liquor hole opening as large as possible, can not be less than the cotton cross-section of drain at least and just can realize better oil feed purpose. However, when the opening is relatively large, when the adsorption reaches a saturated state, the liquid-guiding cotton can seep out of the electronic cigarette liquid, the seeped electronic cigarette liquid drops gather under the electronic cigarette liquid, and the seeped electronic cigarette liquid can flow out from the air inlet hole to a certain extent, but the general air inlet hole cannot be closed, and because the air cannot be admitted after the air inlet hole is closed, smoking cannot be performed. The effect of the electronic cigarette liquid from the outside is that the electronic cigarette liquid flows out from the air inlet hole, and cleaning and feeling are affected.
Secondly, because the electronic cigarette is by the hot atomizing tobacco juice of heating wire, when the power is put through in the long-time atomizing, because the electronic cigarette liquid storage chamber is generally closed, along with the consumption of tobacco juice, form certain negative pressure in the liquid storage chamber easily, because the existence of negative pressure, even bigger feed liquor hole also can not be fine satisfy the demand of feed liquor, cause the electronic cigarette liquid supply not to go up, just can produce the dry combustion method phenomenon of heating wire and liquid guide cotton when supplying not to go up the electronic cigarette liquid. Not only greatly improves the temperature of the sucked fog, but also is easy to burn the mouth and is difficult for the smoker to feel acceptable. Meanwhile, due to the occurrence of the dry heating phenomenon, the danger of sucking the electronic cigarette is greatly increased, and the service life of the atomizing core is also greatly reduced.
In view of the above, the present inventors devised an electronic cigarette atomizing core for sucking and supplying liquid, which can overcome the above-mentioned drawbacks, and can solve the above-mentioned problems well.
Disclosure of Invention
The invention aims to provide a suction liquid supply electronic cigarette atomization core which can generate larger negative pressure through suction so as to offset the negative pressure of a liquid storage chamber and enhance the liquid supply effect.
The invention discloses a suction liquid supply electronic cigarette atomization core, which comprises an atomization core shell, an electric heating wire, liquid guide cotton and an electrode base. The atomizing core shell is provided with a throat part with a smaller inner diameter, the electric heating wire and the liquid guide cotton are arranged at the throat part, and the atomizing core shell of the throat part is provided with a liquid inlet.

The liquid inlet holes on the atomizing core shell are a plurality of strip-shaped grid holes, the lengths of the grid holes extend along the axial direction, and the grid holes are uniformly arranged in the circumferential direction.
The liquid inlet holes on the atomizing core shell are a plurality of strip-shaped grid holes, the length direction of the grid holes extends along the circumference, and the arrangement of the grid holes is in the axial direction.
The liquid inlet holes on the atomizing core shell are formed in the wall of the atomizing core shell, and one or more than one liquid inlet holes are formed in the wall of the atomizing core shell and are arranged along the circumferential direction.
The liquid inlet holes on the atomizing core shell are a plurality of sieve holes and are uniformly distributed at the position above the throat part of the atomizing core shell.
The atomization core disclosed by the invention utilizes a venturi principle which is commonly used in physics, an inward protruding throat part is arranged at a liquid inlet of the atomization core shell, so that the caliber of the position is reduced, the airflow velocity at the position is increased when the electronic cigarette is sucked, a certain negative pressure area is further generated, the negative pressure can act on liquid outside the liquid inlet, so that the indoor negative pressure generated when the liquid storage chamber naturally consumes the liquid is overcome, the electronic cigarette liquid is further enabled to quickly flow into the liquid guide cotton, and then the electronic cigarette liquid enters a heating area for heating and atomizing. Because the atomization core sucks the electronic cigarette liquid into the atomization core through the suction effect, the area of the liquid inlet hole can be made smaller, and even the structure of the sieve-shaped holes or the grid-shaped holes can be used. The screen holes or the grid hole structure can form a tension film under the action of the surface tension of the smoke liquid, and can naturally stop liquid supply when not sucking, so that liquid leakage can be effectively avoided.
