Through the excellent taste and fashionable and versatile appearance, it is portable and easy to use to meet the needs of consumers, so as to achieve a high repurchase rate. Through multiple extensions of the debugging and research and development cycle, the solution to the oil leakage problem is proposed: the first is to reduce the combination For accessories, triple silicone seals are added, and the base and the sealing ring are integrally formed; secondly, we have also developed self-developed condensate tank treatment measures, which also reduces the risk of oil leakage. After long-term research and development and repeated testing, w020 uses the brand new Cotton Ceramics (cotton wrapped ceramic) composite atomization technology, allowing users to have a better taste and user experience.
