Composite tar guide structure and forming method thereof

Abstract

The invention provides a composite tar guide structure comprising an tar guide channel, a tar guide channel, a liquid guide piece and a heating part; the tar guide channel is provided with an inner wall and an outer wall, a tar guide hole penetrates through the inner wall and the outer wall, and tobacco tar in the tar guide channel flows out through the tar guide hole; the outer wall is coated with the liquid guide piece, and the direction of fiber capillary holes in the liquid guide piece is parallel to the direction in which tobacco tar enters the liquid guide piece; the heating part is arranged on the outer side of the liquid guide piece. Compared with a traditional mode of feeding tar from two ends, the composite tar guide structure has the advantages that the resistance of the tobaccotar entering the fiber capillary holes is greatly reduced; tobacco tar adsorbed by the liquid guide piece is atomized through a heating wire, the defects of insufficient tobacco tar supply and insufficient tobacco tar adsorption of the liquid guide piece do not need to be worried about, it is guaranteed that the tobacco tar in the tar guide channel is sufficient, then balance of the tobacco tar adsorbed by all positions of the liquid guide piece is guaranteed, and burning of the middle of the tar guide cotton due to high temperature of the heating wire is avoided. The entering efficiency andspeed of the tobacco tar are guaranteed, the flowing speed of the tobacco tar in the liquid guide piece is also guaranteed, and dry burning is effectively prevented.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a composite oil-conducting structure for electronic cigarettes and a forming method thereof. Background technique [0002] An electronic cigarette commonly used at present, also known as an aerosol generating device, includes an atomizer and a battery body, the atomizer is fixed on the upper surface of the battery body through threads, the atomizer includes a base, the base of the base A smoke channel is set in the center, an atomizing core is set in the smoke channel, a mouthpiece is set on the upper part of the smoke channel, a shell is set on the edge of the base, an oil tank is formed between the inner wall of the shell and the outer wall of the smoke channel, and the smoke channel An oil inlet hole is opened, and the smoke oil flows to the atomizing core through the oil inlet hole. After atomization, the smoke oil flows out through the mouthpiece, and the base also has a...

Problems solved by technology

Therefore, the oil conduction is smooth in this direction. On the contrary, there are relatively few similar channels formed in the direction perpendicular to the oil guide cotton fiber, thus forming a similar layer barrier, which is not conducive to the smooth passage of oil. The main reason

[0004] For a clearer understanding, an example is given below. The oil-conducting cotton is generally designed in a flat form, that is, the cotton is first stretched and compressed into a flat shape, and the horizontally extending flat-shaped oil-conducting cotton is used as an example for illustration. The oil cotton is rolled into a column, and then the heating wire is wound around it. When the oil-conducting cotton is flat, the internal fiber pores extend along the horizontal direction, and the smoke oil enters from both sides, that is, the smoke The way the oil enters is different from the direction in which the capillary pores of the fiber extend. To be precise, they are both vertical. Therefore, it is difficult for the e-liquid to enter the oil-conducting cotton from both sides. The fluidity of oil in the oil guide cotton, such as figure 1 The cross-sectional view of the oil-guiding cotton, the direction of the fiber capillary in the oil-guiding cotton extends along the circumference of the cylinder, and the e-liquid enters from both sides of the cylinder, the resistance to oil inlet is relatively large, and the fluidity of the e-liquid in the oil-guiding cotton is poor
