E-liquid bottle for electronic cigarette

An e-liquid bottle used in an electronic cigarette comprising a main body for receiving e-liquid therein and an e-liquid injecting member mounted on a bottleneck of the main body, the e-liquid injecting member comprising:

• a sleeve with a chamber being formed inside the sleeve for storing e-liquid therein;
• a single valve connected between the bottleneck and an e-liquid suction portion of the chamber for controlling the e-liquid in the main body flow to the chamber;
• a piston installed in an e-liquid feeding portion of the chamber and moving up and down along an axial direction of the chamber;
• an e-liquid guiding pipe formed on the piston and extending into the sleeve;
• a base mounted on the sleeve to engage with the e-liquid guiding pipe and driven by the piston move back and forth along the axial direction of the chamber to control the pressure of the chamber;
• an e-liquid feeding tube connected to an e-liquid outlet of the e-liquid guiding pipe;
• and wherein
• an interval is formed between the piston and the base so that the piston can move along the interval towards the chamber to separate the e-liquid guiding pipe from the base and then connect an e-liquid inlet of the e-liquid guiding pipe with the chamber.
