Aquarium Filter Retainer Prevents Liquid Drip During Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing plug-in-card type liquid purifying and filtering devices for aquarium breeding tanks face issues with liquid dripping during filter replacement, leading to messy and inconvenient maintenance, as well as splashing or vaporization of liquid when the top cap is disassembled.
Innovation Solution
The implementation of disassembled filtering and top cap retainers that allow for the drainage of liquid from the filter plug-in card and top cap before removal, preventing dripping and simplifying the replacement process by refluxing the liquid back into the filtering cylinder or water body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filtering plug-in card is periodically replaced, then the filtering function is maintained, but liquid drips during replacement requiring cleaning operations
Solution Approach 1:
The patent introduces a drainage groove that guides liquid to drain before the filtering plug-in card is fully removed. This preliminary drainage action prevents liquid from dripping during the replacement process, eliminating the need for post-replacement cleaning operations while maintaining the filtering function.
2Ease of repair
If the top cap is disassembled for maintenance, then the filtering plug-in card can be replaced, but liquid splashes or vaporizes onto the cap causing additional cleaning needs
Solution Approach 1:
The drainage groove is positioned to activate before the top cap is completely removed, allowing liquid to drain away from the cap area. This preliminary drainage prevents liquid from splashing or vaporizing onto the cap during disassembly, eliminating the harmful effect of liquid contamination on surrounding areas.
3Adaptability or versatility
If the filtering plug-in card is made detachable for periodic replacement, then maintenance is enabled, but liquid attached to the card drips during removal
Solution Approach 1:
The drainage groove acts as an intermediary structure between the filtering plug-in card and the external environment. It provides a controlled pathway for liquid to drain away from the card during removal, preventing uncontrolled dripping while maintaining the detachable design for periodic maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables a clean, simple, and convenient replacement process for the filtering plug-in card and top cap, reducing the risk of liquid spills and maintaining the device's functionality without additional cleaning steps.
Implementation Method 1
the said drainage groove extends from above the bunghole of the filtering cylinder to below the liquid level in the filtering cylinder

AI summary
The present invention relates to the method for preventing the liquid in the filtering plug-in card form dripping and a plug-in-card type liquid purifying and filtering device. The said liquid purifying and filtering device comprises the water pump, filtering cylinder and filtering plug-in card. In particular, at the top of the said filtering cylinder is equipped with the disassembled filtering plug-in card retainer. When the filtering plug-in card is taken out, such disassembled filtering plug-in card retainer is utilized to place the said filtering plug-in card, thus enabling such filtering plug-in card to leave the liquid level inside the filtering cylinder. In addition, it can set the disassembled top cap retainer for the said filtering cylinder. When the said top cap is disassembled, the disassembled top cap retainer is used to place the said top cap. In the course of replacing the said filtering plug-in card in the present invention, the liquid attached to the filtering plug-in card and liquid attached to the underside of the top cap are refluxed into the filter cylinder or water body, thus effectively preventing the liquid from dripping during the replacement of the filtering plug-in card and enabling the process of replacing the filtering plug-in card to be clean, simple and convenient.
