AI Technical Summary
Existing e-cigarettes have limited filtration capabilities and cannot effectively improve the flavor of the vapor. Furthermore, the e-liquid reservoir only has storage and preliminary filtration functions, lacking a diverse flavor experience.
HNB particulate filter cotton is added between the oil storage cotton and the atomizing core assembly. The HNB particulate filter cotton is used to further filter impurities and add different flavors, similar to the way flavorings are added in traditional tobacco products. The aroma is released stably in particulate form.
It achieves more effective impurity filtration and a more diverse flavor experience, improving the safety of e-cigarettes and consumer choice, and meeting the taste needs of different customers.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an e-cigarette cartridge with HNB granular filter cotton. Background Technology
[0002] Current e-cigarettes use a reservoir cotton to store and initially filter e-liquid before supplying it to the atomizer coil for atomization. This design effectively prevents e-liquid from directly contacting the atomizer coil, reducing coil burn-in; simultaneously, the reservoir cotton's absorbent properties ensure even distribution of e-liquid to the coil. However, relying solely on the reservoir cotton for filtration has limited effectiveness. Moreover, the reservoir cotton only stores and filters e-liquid; it has no effect on altering the flavor of the vapor. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an e-cigarette cartridge with HNB granular filter cotton; it can not only further filter impurities, but also add different flavors to the cartridge.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] It includes an atomizing core assembly and a reservoir cotton; the reservoir cotton wraps around the atomizing core assembly; it also includes a filter cotton, which is disposed between the atomizing core assembly and the reservoir cotton.
[0006] The filter cotton mentioned is HNB granular filter cotton.
[0007] This invention adds HNB granular filter cotton between the oil storage cotton and the atomizing core assembly; the e-liquid passes through the oil storage cotton and then through the HNB granular filter cotton. The HNB granular filter cotton not only further filters impurities but also adds different flavors to the e-liquid cartridge; it also avoids the off-flavors that may result from direct atomization of traditional e-liquid. The HNB granular filter cotton uses a technology similar to adding flavorings to traditional tobacco products, but releases the aroma more stably through granular form. The HNB granular filter cotton, with its own different flavors, satisfies the diverse taste preferences of different customers; fruit, mint, tea, and other flavorings can be added as needed, thus providing a diverse flavor experience without changing the composition of the e-liquid itself. Consumers can choose different types of e-liquid cartridges according to their taste preferences, and this personalized design is highly competitive in the market. The HNB product itself is designed with the concept of "heat-not-burn," reducing the release of harmful substances compared to traditional tobacco products; further improving product safety. Therefore, the e-liquid cartridge design of this invention combines the advantages of oil storage, flavor enhancement through granular filter cotton, and e-liquid supply through the atomizing core, and has broad development prospects. 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 cartridge of this utility model. Detailed Implementation
[0010] 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.
[0011] like Figure 1 As shown, the present invention's e-cigarette cartridge includes an atomizing core assembly 1, an oil-retaining cotton 2, and a filter cotton 3. The filter cotton 3 wraps around the atomizing core assembly 1, and the oil-retaining cotton 2 wraps around the filter cotton 3. The aforementioned filter cotton 3 is HNB (Heat Not Burning) granular filter cotton. By heating the cartridge to a certain temperature (usually 280℃-350℃), the nicotine and flavoring substances in the tobacco volatilize to produce smoke, avoiding direct combustion of the tobacco.
[0012] The structure of the remaining parts of the electronic cigarette cartridge of this utility model is shown in the figure. The remaining parts are not related to the implementation of the above technical solution, nor are they limited to those shown in the figure; they will not be described in detail here.
