AI Technical Summary

Technical Problem

Existing large-capacity visible e-liquid tanks pose a risk of leakage, especially due to excessive oil pressure caused by the weight of the e-liquid itself. This can lead to failure of the sealing structure or the insulated cotton in the coil being unable to withstand the oil pressure, resulting in leakage and affecting the safety of using e-cigarettes.

Method used

It adopts a partitioned oil tank design, including a large oil tank, a small oil tank and a secondary oil tank, which are separated by partitions to form a three-level oil storage space. The overflow port and oil inlet design reduce the oil pressure on the atomizer core, and the transparent window allows for visualization of the e-liquid.

Benefits of technology

It effectively prevents the risk of oil leakage, ensures that the atomizer core does not leak oil when used at high power, improves the lifespan and user experience of e-cigarettes, simplifies structural design, and reduces production costs.

Abstract

The invention provides a large-capacity visible oil bin and an electronic cigarette with the large-capacity visible oil bin. The problem that an existing electronic cigarette product with a visible oil bin leaks oil due to oil pressure and air negative pressure is solved. The visible oil bin comprises a shell and an atomizing core, an oil storage bin is formed in the space between the shell and the atomizing core, a first partition plate is arranged in the oil storage bin, the first partition plate encloses the atomizing core and is connected with the shell to form an inner side cavity which is a small oil bin, and an outer side cavity is a large oil bin; a second annular partition plate on the inner side of the small oil bin and in the circumferential direction of the atomizing core forms a second-stage oil bin in the small oil bin; an overflow port is formed in the top of the first partition plate, an overflow port is formed in the bottom of the second partition plate and an oil inlet is formed in the bottom of the atomizing core. According to the technical scheme, the interior of the oil storage cavity is divided into the three oil cavities with the gradually-decreased spaces through the partition plates, therefore, oil pressure borne by the atomization core is reduced, the oil leakage risk caused by the fact that oil locking cotton of the atomization core bears too large oil pressure is reduced, the oil bin in the technical scheme is simple in structure, and the production cost is saved.
