AI Technical Summary
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.
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.
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.
