Electronic cigarette without atomization tube
By using a cotton-coated tube instead of an atomizing tube in electronic cigarettes, the oil-guiding cotton and oil-reservoir cotton are in direct contact, which solves the problems of increased cost and assembly difficulties associated with atomizing tubes, and improves the flavor of the vapor and oil intake efficiency.

AI Technical Summary
The existing atomizing tube design in electronic cigarettes increases costs and is prone to cotton chipping during assembly.
A cotton-coated tube is used instead of an atomizing tube. The oil-guiding cotton and heating wire are assembled together in the atomizing channel, and the oil-guiding cotton and oil-storage cotton are in direct contact, thus eliminating the need for an atomizing tube.
It improves the moistness of the vapor, avoids assembly problems caused by the atomizing tube, and enhances the oil intake efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette without an atomizing tube. Background Technology
[0002] Electronic cigarettes typically consist of a reservoir of e-liquid containing a hollow core that forms an atomization channel. Inside this channel is an atomization tube, which contains wicking material and a heating coil. When the heating coil is activated, it atomizes the e-liquid into vapor for the user to inhale. The presence of an atomization tube outside the heating coil increases the cost of the tube and also makes it easier to accidentally scrape off the wicking material during assembly. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an electronic cigarette that does not have an atomizing tube, thus avoiding the problems caused by having an atomizing tube.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] It includes an oil cup, oil storage cotton, heating wire, and oil guiding cotton. The oil cup is filled with oil storage cotton. The oil storage cotton is hollow to form an atomization channel. The oil guiding cotton is wrapped around the heating wire. The feature is that it also includes a cotton-wrapping tube. The oil guiding cotton is wrapped around the cotton-wrapping tube and then assembled in the atomization channel.
[0006] After the oil-guiding cotton and heating wire are assembled in the atomization channel, the cotton-wrapping tube is removed, and the oil-guiding cotton and oil-storing cotton are in direct contact.
[0007] This invention replaces the original atomizing tube with a cotton-wrapped tube. After assembly, the tube is inserted into the atomizing channel of the oil-collecting cotton in the oil cup. By pulling out the cotton-wrapped tube, the atomizing tube is eliminated. By eliminating the atomizing tube, the contact area between the oil-guiding cotton and the oil-collecting cotton is increased, improving the oil intake efficiency and resulting in a more moist and delicate flavor in the vapor.

[0011] Figure 3 This is a three-dimensional exploded view of the oil-guiding cotton 3, heating wire 4, and cotton-wrapped tube 5 of this utility model;
[0012] Figure 4 This is a diagram showing the assembly process of the oil-guiding cotton 3, heating wire 4, and cotton-wrapping tube 5 components of this utility model. Detailed Implementation
[0013] like Figure 1-4 As shown, this utility model includes an oil cup 1, an oil storage cotton 2, a heating wire 4, an oil guiding cotton 3, and a cotton-wrapping tube 5. The oil cup 1 is filled with oil storage cotton 2; the oil storage cotton 2 is hollow to form an atomization channel 21; the oil guiding cotton 3 is wrapped around the heating wire 4.
[0014] like Figure 2 , 4 As shown, after the oil-guiding cotton 3 is wrapped with the cotton-wrapping tube 5, the oil-guiding cotton 3, heating wire 4, and cotton-wrapping tube 5 assembly is assembled in the atomization channel 21. After assembly, the cotton-wrapping tube 5 is removed, and the oil-guiding cotton 3 and the oil-retaining cotton 2 are in direct contact; thus avoiding the need for an atomization tube.
[0015] The solution using this invention allows for adjustment of the thickness of the heating wire and the density of the oil storage cotton according to actual needs, avoiding shrinkage of the central hole and excessively fast oil inlet rate.
[0016] The above embodiments are descriptions of specific implementations of this utility model and are not intended to limit this utility model; all equivalent modifications that can be obtained from the above description should be within the protection scope of this utility model.
