Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an atomizing core that utilizes capillary action to supply oil. Background Technology

[0002] Existing e-cigarettes are plagued by issues such as oil leakage and burnt coils in areas like the atomizer core. Leakage frequently occurs during transportation, rendering the entire product unusable. During use, condensation can also affect the normal operation and performance of the e-cigarette, leading to a poor user experience. Utility Model Content

[0003] The technical problem solved by this invention is to provide an electronic cigarette atomizing core that utilizes capillary action to supply oil, thereby improving common problems such as oil leakage and burnt cores in open-oil electronic cigarettes.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The atomizing core includes an outer steel tube, oil storage cotton, an atomizing tube, oil guiding cotton, and a heating wire; the tubular outer steel tube contains oil storage cotton and an oil inlet; the oil storage cotton is fitted inside the atomizing tube, the atomizing tube is fitted inside the oil guiding cotton, and the oil guiding cotton is fitted inside the heating wire; the oil storage cotton is characterized in that: the oil storage cotton is divided into three sections: upper oil storage cotton, steel sheet silicone, and lower oil storage cotton; a radial oil storage cavity communicating with the oil inlet is provided on the steel sheet silicone; axial holes are provided in the upper and lower directions of the radial oil storage cavity, communicating with the radial oil storage cavity and the upper and lower oil storage cotton.

[0006] An upper steel sheet is provided between the steel sheet silicone and the upper oil-retaining cotton; an upper steel sheet hole is provided on the upper steel sheet and communicates with the axial hole; a lower steel sheet is provided between the steel sheet silicone and the lower oil-retaining cotton; a lower steel sheet hole is provided on the lower steel sheet and communicates with the axial hole; the upper steel sheet hole is larger than the lower steel sheet hole.

[0007] The oil inlet holes are arranged in multiple circumferences; the radial oil storage chambers are arranged in multiple circumferences corresponding to the oil inlet holes.

[0008] The atomizing tube is provided with an oil passage hole that communicates with the upper and lower oil storage cotton.

[0009] The axial dimension of the upper oil-storing cotton is greater than that of the lower oil-storing cotton.

[0010] In this invention, e-liquid enters the radial oil storage chamber through the inlet hole, and is supplied to the upper oil storage cotton through the upper steel plate hole and the lower oil storage cotton through the lower steel plate hole. The e-liquid in the upper and lower oil storage cotton passes through the atomizing tube and the wicking cotton before reaching the heating coil. This creates a capillary effect between the e-liquid and the upper and lower oil storage cotton, ensuring no leakage. The upper steel plate hole diameter is enlarged, and the lower steel plate hole diameter is reduced, ensuring that the upper oil storage cotton above the upper steel plate can absorb sufficient e-liquid. The upper oil storage cotton also absorbs condensate, reducing the risk of flavor alteration caused by condensate buildup flowing back to the atomizing coil. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings:

[0015] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0016] like Figure 1 , 2 As shown in Figure 3, the atomizing core of this utility model includes an outer steel tube 1, an oil storage cotton 2, an atomizing tube 3, an oil guiding cotton 4, and a heating wire 5. The tubular outer steel tube 1 contains the oil storage cotton 2, and multiple oil inlets 11 are arranged along the circumference at the lower middle section. The atomizing tube 3 is fitted inside the oil storage cotton 2, the oil guiding cotton 4 is fitted inside the atomizing tube 3, and the heating wire 5 is fitted inside the oil guiding cotton 4.

[0017] The oil-storing cotton 2 is divided into three sections: upper oil-storing cotton 21, steel-plate silicone rubber 22, and lower oil-storing cotton 23. The axial dimension of the upper oil-storing cotton 21 is larger than that of the lower oil-storing cotton 23. The steel-plate silicone rubber 22 has a radially arranged oil-storing cavity 24 communicating with the oil inlet hole 11. Axial holes 25 are provided in both the upper and lower directions of the radial oil-storing cavity 24, communicating with the upper oil-storing cotton 21 and the lower oil-storing cotton 23. Furthermore, an upper steel plate 26 is provided between the steel-plate silicone rubber 22 and the upper oil-storing cotton 21; an upper steel plate hole 27 communicating with the axial hole 25 is provided on the upper steel plate 26. A lower steel plate 28 is provided between the steel-plate silicone rubber 22 and the lower oil-storing cotton 23; a lower steel plate hole 29 communicating with the axial hole 25 is provided on the lower steel plate 28. The upper steel plate hole 27 is larger than the lower steel plate hole 29.

[0018] An oil passage 31 is provided on the atomizing tube 3, which communicates with the upper oil storage cotton 21 and the lower oil storage cotton 23.

[0019] During use, e-liquid enters the radial reservoir 24 through the inlet 11; then it reaches the upper reservoir 21 through the axial hole 25 and the upper steel plate hole 27, and the lower reservoir 23 through the axial hole 24 and the lower steel plate hole 29. The e-liquid stored in the upper and lower reservoirs enters the wicking cotton 4 through the oil passage 31 on the atomizing tube 3; thus, it can be atomized by the atomizing coil 5. During inhalation, if some of the vapor condenses to form condensate, it can be drawn into the upper reservoir 21 through the top of the upper reservoir 21.

[0020] The remaining parts of this utility model electronic cigarette are not limited to those shown in the figure, and are unrelated to the implementation of the aforementioned scheme; they will not be described in detail here.
