AI Technical Summary

⚠Technical Problem

Existing liquid storage bottles leave liquid residue after refilling, causing contamination of users' hands and the surrounding environment.

⚗Method used

Design a liquid storage bottle with two parallel fluid channels and a connecting channel inside the nozzle. The inner circumference of the connecting channel is inclined towards the fluid channels to ensure that the liquid flows completely into the liquid tank and avoids residue.

🎯Benefits of technology

After the liquid is replenished, there is almost no liquid residue, which reduces the risk of contamination and improves replenishment efficiency and safety.

Abstract

This invention relates to liquid storage bottles and liquid replenishment systems. A liquid storage bottle is provided that can discharge liquid while preventing liquid residue stored therein. The liquid storage bottle has a bottle body and a nozzle for dispensing liquid stored in the bottle body. A first fluid channel, a second fluid channel, and a connecting channel are formed inside the nozzle. Each of the first and second fluid channels opens outwards at the tip of the nozzle and is parallel to each other. The connecting channel opens inwards into the bottle body at the base of the nozzle and communicates with the first and second fluid channels. The inner circumferential surface of the connecting channel is inclined inwards towards the first and second fluid channels.
