Description

Liquid storage device

【Technical field】

This case is about a liquid storage device, especially a liquid storage device suitable for electronic cigarettes.

【Background technique】

The use of electronic cigarettes, or so-called electronic cigarettes, is rapidly expanding as an alternative to traditional cigarettes that smoke real tobacco. However, it is known that there are still some differences in the feeling of smoking between electronic cigarettes and real cigarettes. For example, when people smoke, because the cigarette liquid cannot precisely control the penetration amount, the phenomenon of uneven cigarette liquid occurs, resulting in the part with a small amount of cigarette liquid. The droplets are not uniform, and when heated by an electric heater to produce burnt smoke, the smoker will feel unpleasant taste.

In addition, it is known that electronic cigarettes cannot precisely control the amount of penetration, especially when the suction nozzle is facing upwards, the cigarette liquid cannot completely stop the penetration of the cigarette liquid due to the downward gravity, and the cigarette liquid will drip when the cigarette liquid is full. It leaks to the outside air intake, causing oil leakage.

Furthermore, the known electronic cigarette liquid storage device is designed to be integrated with the atomizing component of the electronic cigarette and cannot be separated, disassembled and replaced. The entire structure of the chemical components is also discarded, and the user needs to use it again, which will not only increase the purchase cost of the electronic cigarette; in addition, the liquid storage device of the electronic cigarette oil can also be designed to be backfilled and replenished, but such a design is afraid. People who are interested in filling unknown liquids (such as drugs) for illegal smoking use. Therefore, considering the factors of illegal use, it is necessary to improve the design of the liquid storage device of e-liquid.

In view of this, how to develop an electronic cigarette that can improve the above-mentioned deficiencies in the known electronic cigarette technology, develop an electronic cigarette that replaces real cigarettes, and provide a detachable electronic cigarette oil storage device is an urgent need to solve at present. question.

[Content of the invention]

The main purpose of this case is to provide a liquid storage device, which is designed for the liquid storage device of electronic cigarette oil to be detachably replaced and re-installed on the electronic cigarette device, and then cooperated with the design that the liquid storage bag is completely enclosed in the liquid storage body. It is no longer possible to refill the e-liquid and can only be used for a single replacement to prevent the liquid storage bag from being repeatedly filled with illegal injection needles. Moreover, the liquid storage device is composed of a liquid conveyor combined with the liquid storage bag to form a controllable switch for precise control. The quantitative and high-efficiency control output of cigarette liquid can solve the problems of uneven liquid and oil leakage of cigarettes in the known electronic cigarette technology.

The main purpose of this case is to provide a liquid storage device, suitable for an electronic cigarette, comprising: a liquid storage body, each with an opening at both ends, and a accommodating groove and a liquid flow channel between the openings at the two ends. The two ends of the accommodating tank and the liquid flow channel are connected to the opening: a liquid storage bag is accommodated in the accommodating tank to store a storage liquid, and a liquid outlet is provided for The liquid is discharged; a liquid conveyer covers the opening of the liquid storage body, and has a liquid inlet pipe channel for connecting with the liquid outlet of the liquid storage bag, and a liquid outlet chamber for the liquid The flow channel is communicated with each other; and a cover plate covers the other opening of the liquid storage body and has an outlet pipe for communicating with the liquid flow channel; wherein, the liquid conveyer is driven to store the liquid storage bag The liquid is drawn from the liquid outlet, and is output from the liquid outlet chamber to the liquid flow channel in a controlled quantity, so as to achieve quantitative control and discharge outside the liquid storage body.
