Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, specifically to an atomizing core that can prevent oil leakage and absorb condensate. Background Technology
[0002] Leakage has long been a problem plaguing the e-cigarette industry. Existing e-cigarette products with visible oil often leak during transportation, rendering the entire product unusable. Furthermore, condensation is generated during use; if this condensation is not absorbed effectively and promptly, it can also affect the normal use and performance of the e-cigarette, leading to a poor user experience. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an atomizing core that can prevent oil leakage and absorb condensate; the atomizing core can prevent oil leakage and absorb condensate, thereby improving the performance and reliability of 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-collecting cotton, a heating wire support, and a heating wire; the oil-collecting cotton is installed inside the outer steel tube; the oil-collecting cotton is hollow, and the heating wire support is installed in the hollow position; the heating wire is arranged on the heating wire support; the oil-collecting cotton is divided into upper oil-collecting cotton, lower oil-collecting cotton, and oil-absorbing cotton; from top to bottom, they are upper oil-collecting cotton, oil-absorbing cotton, and lower oil-collecting cotton; the oil-absorbing cotton is provided with oil passage holes for e-liquid to pass through.
[0006] The oil-absorbing cotton is thin in the axial direction relative to the upper and lower oil-absorbing cotton.
[0007] The oil passages described herein are arranged in multiple circumferences.
[0008] The heating wire support and heating wire are located at the center of the lower oil storage cotton.
[0009] This invention relates to a transparent e-cigarette. During transportation, the e-liquid is subjected to negative pressure and high temperatures. Any spilled e-liquid is absorbed by the lower reservoir cotton, while any excess is guided to the upper reservoir cotton via liquid drainage. This significantly reduces the risk of e-liquid leakage, improving the safety and reliability of the e-cigarette. Simultaneously, the upper reservoir cotton absorbs not only the e-liquid guided from the lower reservoir cotton but also condensate formed during use. The intermediate absorbent cotton acts as a barrier; if the upper reservoir cotton reaches saturation with condensate, the intermediate absorbent cotton prevents condensate from flowing into the lower reservoir cotton, thus avoiding any impact on the flavor and extending the e-cigarette's lifespan. The reservoir cotton of this invention provides a uniform supply of e-liquid to the heating element, ensuring complete atomization and improving atomization quality for a better user experience. Attached Figure Description
[0010] The present invention will be further described below with reference to the accompanying drawings:
[0011] Figure 1 This is a three-dimensional exploded view of the atomizing core of this utility model;
[0012] Figure 2 This is a cross-sectional view of the atomizing core of this utility model in its assembled state. Detailed Implementation
[0013] 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.
[0014] like Figure 1 , 2 As shown, the atomizing core of this utility model includes an outer steel tube 1, an oil-collecting cotton 2, a heating wire support 3, and a heating wire 4. The oil-collecting cotton 2 is disposed inside the outer steel tube 1; the oil-collecting cotton 2 is hollow, and the heating wire support 3 is disposed in the hollow position; the heating wire 4 is arranged on the heating wire support 3. Specifically, the oil-collecting cotton 2 is divided into an upper oil-collecting cotton 21, a lower oil-collecting cotton 23, and an oil-absorbing cotton 22; from top to bottom, they are the upper oil-collecting cotton 21, the oil-absorbing cotton 22, and the lower oil-collecting cotton 23; the oil-absorbing cotton 22 has multiple oil-passing holes 221 arranged along its circumference for the e-liquid to pass through. The oil-absorbing cotton 22 is thinner in the axial direction than the upper oil-collecting cotton 21 and the lower oil-collecting cotton 23. The heating wire support 3 and the heating wire 4 are located at the center of the lower oil-collecting cotton 23.
[0015] like Figure 2 As shown, the oil tank 5 is filled with e-liquid. After the oil tank is filled with e-liquid, another 50% of the volume of the lower oil storage cotton 23 is added to the oil tank 5. An oil film is formed at the contact position between the surface of the lower oil storage cotton 23 and the oil inlet hole 11 of the outer steel pipe 1, so that the pressure of the e-liquid in the oil tank 5 itself, the external air pressure, and the tension formed on the surface of the lower oil storage cotton 23 reach a steady state.
[0016] During transportation, e-liquid that leaks due to environmental factors will first overflow into the blank part of the lower oil-retaining cotton 23. When the overflow volume is greater than that of the lower oil-retaining cotton 23, the e-liquid will flow upward along the direction of the yarn in the oil-retaining cotton (the direction of the oil-retaining cotton yarn is a single longitudinal direction) and be received by the upper oil-retaining cotton 21. At the same time, some e-liquid will be absorbed by the oil-absorbing cotton 22 under the adsorption force of the cotton.
[0017] When using an e-cigarette, residual atomized e-liquid will diffuse in the airway. At this time, the upper oil reservoir 21 will absorb the residual atomized e-liquid inside the airway. Meanwhile, the condensate that condenses on the mouthpiece wall will also flow to the upper oil reservoir 21 under the action of the mouthpiece structure and gravity, and then be absorbed and stored.
[0018] The atomizing core of this invention is not limited to that shown in the figure, and the structure of the rest of the electronic cigarette is unrelated to the implementation of the aforementioned scheme; it will not be described in detail here.
