Liquid Container Connecting Structure for Leak Prevention During Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid dispensers face issues with stability during liquid transfer, particularly when the bottle is tilted, leading to potential leakage, and the engagement process is cumbersome and time-consuming.
Innovation Solution
A connecting structure featuring a receiving groove, locking assembly, and a sleeve that allows rapid connection and disconnection of a liquid container, ensuring liquid containment even when tilted, through a four-bar linkage mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottle is turned upside down to insert into the liquid dispenser via gravity, then the liquid can flow into the dispenser, but the dispenser must remain stable and cannot shake to prevent the bottle from disengaging and causing leakage
Solution Approach 1:
The patent employs a dynamic locking mechanism that transitions between locked and unlocked states. The locking assembly includes a locking arm that can swing between a locked position (where it engages with the bottle) and an unlocked position, allowing the system to adapt between stable liquid transfer and easy bottle removal based on operational needs
2Reliability
If the bottle is engaged with a cap to communicate with a suction tube, then the liquid can be pumped into the dispenser, but engaging the bottle with the cap is troubling and time-consuming
Solution Approach 1:
The patent extracts the cap component from the system and replaces it with a direct bottle-to-suction tube connection mechanism. The suction tube directly communicates with the bottle opening, eliminating the need for separate cap engagement and enabling rapid bottle attachment without time-consuming cap operations
Solution Approach 2:
The locking assembly is segmented into independent components including a locking arm, pressing plate, and supporting structure. This segmentation allows the locking mechanism to function independently from the suction tube and bottle, enabling simplified rapid engagement while maintaining reliable liquid transfer through the suction tube
3Productivity
If a structure allows rapid engagement of the liquid dispenser with the bottle, then the liquid can flow into the dispenser quickly, but the liquid may leak when the liquid container is tilted
Solution Approach 1:
The locking arm is designed to engage with the bottle in a preliminary locking action that prevents tilting and leakage before the liquid transfer begins. The pressing plate applies preliminary force to secure the bottle in place, creating a stable connection that prevents leakage even when the container is tilted during operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and secure attachment of a liquid container to a dispenser, preventing leakage during tilting and facilitating easy replacement without manual effort.
Implementation Method 1
a locking structure comprising a connecting base, a locking assembly, two swinging arms and a sleeve, wherein the connecting base is engaged with a top side of the receiving groove... The two side arms extend along a front-rear direction and extend frontwards out of the connecting base, wherein two front ends of the two side arms are connected to a pressing plate... The liftable base moves along a top-bottom direction in the connecting base and moves along the front-rear direction in the connecting base
Implementation Method 2
A front end of each of the two extending arms is pivotally connected to a front side of each of the two side arms. The left side and the right side of the bottom frame are respectively and pivotally connected to the front end of each of the two swinging arms. A rear end of each of the two swinging arms is pivotally connected to a rear side of one of the two side plates

AI summary
A connecting structure for a liquid container includes a receiving groove. The liquid container having a suction tube is disposed in the receiving groove. A top end of the receiving groove is engaged with a connecting base. A front side of the connecting base is pivotally connected to a locking assembly protruding frontwards. A liftable base being movable along a top-bottom direction and a front-rear direction is disposed in an inner side of the connecting base, and has a bottom frame engaging with a sleeve that is for being connected to and communicating with a liquid pipeline and fits around the suction tube. Two extending arms extending frontwards out of the bottom frame are pivotally connected to the locking assembly. A left side and a right side of the bottom frame are pivotally connected to two swinging arms that extend backwards and are pivotally connected to the connecting base.
