Description
Technical Field
The invention relates to the field of electronic cigarettes, in particular to a composite oil guide structure for an electronic cigarette and a forming method thereof.
Background
At present commonly used electron cigarette, also be called aerial fog generating device, it includes atomizer and battery cell, the atomizer passes through the thread tightening and is in battery cell's upper surface, the atomizer includes the base, and the center of base sets up the flue gas passageway, sets up atomizing core in the flue gas passageway, and the upper portion of flue gas passageway is provided with the cigarette holder, and the edge of base is provided with the shell, encloses into the oil bunker between the inner wall of shell and the outer wall of flue gas passageway, and the inlet port is seted up to the flue gas passageway, and the tobacco tar passes through the inlet port flow direction atomizing core, and atomizing back tobacco tar passes through the cigarette holder and flows, and the inlet port still is seted up to the base, the inlet port is located the below of flue gas passageway, and their two intercommunication, and the. The atomizing core is including leading oily cotton and twining in the heater of leading oily cotton, and the tobacco tar in the oil storehouse passes through the inlet port flow direction and leads the cotton both ends of oily cotton, then flows in the intermediate position department of leading oily cotton, and the heater generates heat, lasts to lead the absorbent tobacco tar atomization of oily cotton.
The oil guide cotton is generally vertically or horizontally placed, but no matter the oil guide cotton is vertically or horizontally placed, the mode that the oil guide cotton is wrapped by the oil guide cotton is winding, or the oil guide cotton is wound by the heating wire or the heating wire is wound by the oil guide cotton, and the mode is also the structural form of two types of atomization cores which are mainstream in the market. In any winding method, the fiber direction of the oil guide cotton is perpendicular to the path direction of the smoke oil in the oil guide cotton, and the oil guide hole formed in the fiber direction of the oil guide cotton is also called as a fiber capillary hole. The main reason is that a plurality of tubular fine oil guide channels are formed in the stretching direction of the oil guide cotton fibers, and fine structure channels surrounded by the oil guide cotton fibers are arranged around the oil guide cotton fibers. Therefore, oil is guided smoothly in the direction, and on the contrary, similar channels formed in the direction perpendicular to the oil guide cotton fibers are fewer, so that similar interlayer baffles are formed, the smooth passing of the oil is not facilitated, and the oil guide is also the main reason of unsmooth oil guide of the atomization core in the current market.
For better understanding, as illustrated below, the oil guiding cotton is generally designed in a flat plate type, that is, the cotton is stretched and compressed to form a flat plate shape, a horizontally extending flat plate-shaped oil guiding cotton is taken as an example for illustration, then the oil guiding cotton is rolled into a column shape, and then the heating wire is wound outside the oil guiding cotton, because the fiber capillary pores in the oil guiding cotton extend along the horizontal direction and the smoke oil enters from two sides when the oil guiding cotton is in the flat plate shape, that is, the smoke oil enters from two sides in a different manner and the fiber capillary pores extend in a perpendicular direction, the smoke oil enters from two sides into the oil guiding cotton more difficultly, the entering is not smooth, the oil inlet resistance is large, and further the mobility of the smoke oil in the oil guiding cotton is further caused, as shown in the sectional view of the oil guiding cotton in fig. 1, the direction of the fiber capillary pores in the oil guiding cotton extends along the circumferential direction of the cylinder, and the smoke oil enters from two sides of the, the oil inlet resistance is large, and the fluidity of the tobacco tar in the oil guide cotton is poor.
Therefore, in order to solve the above problems, it is necessary to design an oil-guiding cotton structure.

In addition, the invention also provides a manufacturing method of the composite oil guide structure, which is simple to operate and convenient for batch operation.
The present design has the advantage that,
1. the tobacco tar has high reduction degree and better taste. Because the oil guide cotton enhances the oil guide capacity, the tail end of the atomizing core can not be carried out in an oil shortage state when the atomizing core works in a pulse mode, so that peculiar smell in the oil shortage process can not be generated, and the reduction degree of the tobacco tar is higher.
2. The mouthfeel was more constant. Due to the improvement of oil supply, the reduction degree is high, the taste is more stable, and a user can not be troubled by the peculiar smell.
3. The service life is longer.
The service life of the atomizing core completely depends on whether the atomizing core is dried or not or the amount of deposited carbon, the drying directly damages the atomizing core, and long-term oil shortage work can cause quick carbonization of the oil guide cotton, increase of the deposited carbon and easy damage to the atomizing core. Because the oil supply state is improved, the two problems can be greatly reduced, and the service life of the atomizing core is prolonged.
4. The atomizing core is cheaper and more environment-friendly.
Due to the fact that the service life is greatly prolonged, the cost of a consumer is reduced, and the environment protection level is relatively improved.
