Why is it difficult to solve the electronic cigarette liquid leaking?

There are many types of electronic cigarettes on the market, but for consumers, almost every electronic cigarette has a pain point, which is the phenomenon of liquid leaking. An average of one third of an e-liquid is a liquid leaking waste. What is liquid leaking? That is, the e liquid flows out in an abnormal manner, for example, from the outside of the atomization chamber glass, the Atomizer base, the outside of the mouthpiece, and the like.

Although there are many problems to solve the problem of electronic cigarette liquid leaking, such as keeping the Atomizer vertical, adjusting the air intake, and often cleaning the Atomizer, etc., these are only analyzed for the use of the consumer, and can not solve the fundamental problem. Why are the waterproof functions of mobile phones, watches and other consumer electronics products almost perfect, even against the invasion of coffee, tea, soda and other liquids, why the problem of liquid leaking of electronic cigarettes has not been solved?

The following small series will briefly analyze the frequent problems of electronic cigarette liquid leaking. The problem of liquid leaking of electronic cigarettes will be analyzed from three aspects: the precision of structural parts, accessories, and product design. Several vapes released recently have been improved on the liquid leaking program. We have learned through these recent vape product solutions that focus on the liquid leaking problem; the popular small smoke flat smoke bomb structure on the market, The general structure is: sealing ring, atomization chamber, guide rod, atomizing core (fiber cotton / ceramic) and other accessories.

Perhaps the anti-liquid leaking design of vapes can refer to the waterproofing of mobile phones. From the three aspects, the following is a look at how the electronic cigarettes on the market are improving against the liquid leaking problem.

First, the atomization core

Faced with changes in the needs of smokers' consumers, McWell's Feelm technology atomization chamber is fully sealed to prevent leakage or dripping of e liquid, while ensuring the degree of taste reduction. At present, LYX and YOOZ are the leak-proof design of this Feelm ceramic atomizing core technology, and the ceramic itself has strong lipophilicity and easy to conduct e liquid. Ceramics will not dry dry compared with cotton and other materials.

Second, Atomizer structure design

Most of the popular oil storage structures on the market are assembled directly from the atomization chamber, guide rod, base, atomizing core and other accessories. The precision between the product structures is high. This combined structure is designed to be sealed. In the case of low sexuality, it is easy to cause up and down the liquid leaking phenomenon.

Third, the seal

For electronic consumer products with high sealing requirements, reinforced coatings and sealed designs are generally used. In addition to the atomization core and the overall structural design, the electronic cigarette has a sealed artifact-seal ring. The sealing ring is distributed in many connection ports of the electronic cigarette. Due to the high material requirements of vapes, Atomizer peripheral materials use FDA food grade materials, and liquid silica gel benefits from its softness, non-toxicity, high temperature resistance, easy molding, etc., and is widely used by LSR injection molding or overmolding. In 3C electronics such as mobile phones, telephone watches and other housings, card holders or interfaces, it plays an important role in sealing and waterproofing. At the same time, the electronic cigarette seal design seal ring also plays an extremely important role.

The Atomizer is combined with the battery rod and most of the product is connected by a sealing ring and thread. The silicone ring is almost distributed in each connection part of the Atomizer to the base. The electronic cigarette thermal silica gel and the thermal conductive silicone sheet are essential accessories for preventing liquid leaking and improving sealing.
