AI Technical Summary
Traditional e-cigarettes often suffer from insufficient e-liquid replenishment due to their supply structure, leading to problems such as dry vaporization or burnt coils.
Design an oil supply structure including an oil tank, an oil storage cotton and an oil guide pipe. The oil tank is divided into two chambers by a partition, and an oil storage cavity is formed outside the oil guide pipe. The e-liquid is retained in the oil storage cavity by the gravity when the e-cigarette is tilted or shaken, and the oil storage cotton is stably replenished through the oil inlet.
It achieves timely and stable e-liquid replenishment, avoiding problems such as dry atomization or burnt coil, and improves the stability of e-cigarette use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an oil supply structure for a bottom-fill bottle electronic cigarette. Background Technology
[0002] Traditional e-cigarettes use e-liquid bottles, which are typically located below the atomizer. The e-liquid in the bottle is usually added to the reservoir by tilting or shaking the e-cigarette. This random replenishment method can easily lead to issues like dry vapor or burnt coils due to untimely replenishment. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an oil supply structure for an electronic cigarette with a lower oil bottle, which can supply oil to the oil storage cotton in a timely and stable manner.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] The oil supply structure includes an oil tank; the bottom of the oil tank is sealed with a silicone support, and a partition is set in the middle of the oil tank to divide the oil tank into two chambers, left and right; one chamber is equipped with an oil storage cotton and an atomizing core, and the other chamber is equipped with an oil guide pipe; an oil bottle can be inserted into the bottom of the oil guide pipe; an oil inlet hole is set at the axial middle position of the partition; a through hole is set on the oil guide pipe above the silicone support, so that the oil guide pipe below the through hole forms an oil storage cavity with the oil tank.
[0006] The through hole and the oil inlet hole are aligned in the axial direction.
[0007] This invention forms an oil storage cavity outside the oil guide tube. When the e-cigarette is tilted or shaken, the e-liquid reaches the cavity. Because the opening of the oil guide tube is positioned higher, the e-liquid below the opening will remain in the cavity. Then, the e-liquid will be stably supplied to the oil storage cotton through the oil inlet hole on the partition. This can greatly improve the problem of dry burning or burnt coil caused by untimely replenishment. Attached Figure Description
[0008] The present invention will be further described below with reference to the accompanying drawings:
[0009] Figure 1 This is a cross-sectional view of the electronic cigarette of this utility model;
[0010] Figure 2 This is a three-dimensional sectional view of the electronic cigarette of this utility model. Detailed Implementation
[0011] 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.
[0012] like Figure 1 , 2 As shown, the oil supply structure of this utility model includes an oil tank 1. The bottom of the oil tank is sealed with a support silicone 7, and a partition 11 is set in the middle of the oil tank 1 to divide the oil tank into left and right chambers; one chamber (the left chamber is shown as an example in the attached figure) is equipped with an oil storage cotton 2 and an atomizing core 3, and the other chamber is equipped with an oil guide pipe 4.
[0013] An oil inlet hole 12 is provided at the axial center position of the partition plate 11; a through hole 41 is provided on the oil guide pipe 4 which is flush with the oil inlet hole 12. Therefore, an oil storage cavity 6 is formed between the oil guide pipe 4 below the through hole 41 and the oil tank 1.
[0014] As shown in the figure, after the oil bottle 5 is installed below the oil guide tube 4, the e-liquid in the oil bottle 5 can enter the oil reservoir 2 through the through hole 41 and the oil inlet 12 of the oil guide tube 4; the oil reservoir 2 then supplies e-liquid to the atomizer coil 3. At the same time, e-liquid will also be retained in the oil storage cavity 6 outside the oil guide tube 4. The retained e-liquid can be stably replenished to the oil reservoir 2 through the oil inlet 12; this can minimize the risk of dry burning or burnt coil caused by untimely e-liquid replenishment.
[0015] The attached figure shows an example of an electronic cigarette structure for the purpose of illustrating the technical solution of this utility model; however, this utility model is not limited to the structure of the remaining parts of the electronic cigarette shown in the figure; the remaining parts are unrelated to the implementation of the aforementioned solution and will not be described in detail here.
