Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional e-liquid bottles for electronic cigarettes are difficult to operate and lack control over e-liquid injection quantity, often resulting in excessive e-liquid delivery and are not reusable.
Innovation Solution
An e-liquid bottle design featuring a main body with an e-liquid injecting member that includes a sleeve, piston, single valve, e-liquid guiding pipe, and base, allowing for controlled e-liquid injection through a piston-driven mechanism, enabling precise quantity control and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual squeezing of e-liquid chamber is used, then e-liquid can be fed into atomizer, but e-liquid injection quantity cannot be controlled precisely
Solution Approach 1:
The piston is designed to move dynamically between a first position (disconnected from base) and second position (connected to base), enabling controlled e-liquid transfer. This dynamic positioning allows precise control over when and how much e-liquid is injected into the atomizer, resolving the contradiction between ease of operation and injection quantity precision.
Solution Approach 2:
The base acts as an intermediary component between the e-liquid chamber and the atomizer. It receives e-liquid from the chamber when the piston moves to the first position and then delivers controlled amounts to the atomizer when the piston moves to the second position, enabling precise quantity control while maintaining ease of operation.
2Device complexity
If conventional e-liquid bottle design is used, then simple structure is achieved, but the bottle cannot be reused
Solution Approach 1:
The e-liquid bottle is segmented into separable components: the main body, the base, and the piston assembly. This segmentation allows the piston to be reset to its initial position after use, enabling the bottle to be refilled and reused multiple times while maintaining a relatively simple overall structure.
Solution Approach 2:
The piston is designed to be reset to its initial position after e-liquid injection, recovering its original state for subsequent use. This recovery mechanism enables the e-liquid bottle to be reused multiple times, extending its service life while keeping the structural complexity manageable.

AI summary
An e-liquid bottle includes 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 includes a sleeve, a chamber 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 flow to the chamber, a piston installed in an e-liquid feeding portion 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 pipe and driven by the piston move back and forth along the chamber to control the pressure in the chamber, an e-liquid feeding tube connected to an e-liquid outlet of the e-liquid guiding pipe. 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 connect an e-liquid inlet of the e-liquid guiding pipe with the chamber.
