Tank Valve Nozzle Head Assembly for Stable Filter Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tank valve devices suffer from a gap between the filter and the C ring, causing the filter to wobble during use, necessitating a more secure assembly structure.
Innovation Solution
A nozzle head design where a lid member is co-fastened with the nozzle body and valve block using a fastening member, securely attaching the filter to the nozzle body by covering its peripheral edge and being fastened together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a C ring is used to attach the filter to the jet flow deflection piece, then the assembly structure is simple, but a gap is formed between the filter and C ring causing the filter to wobble during use
Solution Approach 1:
The patent merges the filter attachment function with the nozzle body structure by forming a recess directly in the nozzle body to receive the filter. This eliminates the need for separate C ring fasteners and integrates multiple functions (support, positioning, and securing) into a single unified structure, thereby eliminating gaps and preventing filter wobbling while maintaining assembly simplicity.
2Reliability
If the filter is securely attached to prevent wobbling, then the attachment stability is improved, but the assembly structure becomes more complex
Solution Approach 1:
The patent segments the nozzle body into functional zones: a recess portion for receiving the filter, a lip portion for sealing against the filter edge, and an outwardly extending portion for structural support. This segmentation allows each zone to perform its specific function efficiently while maintaining an integrated, gapless structure that secures the filter reliably without requiring additional fastening components.

AI summary
This nozzle head of a tank valve device to be attached to a port of a tank includes: a nozzle body fastened to a valve block of the tank valve device by a fastening member and including an outlet passage through which a fluid flows out of the tank; a filter fitting in an entry portion of the outlet passage; and a lid member provided on the entry portion to cover a peripheral edge portion of the filter and including a through-hole corresponding to the outlet passage. The lid member is co-fastened to the valve block by the fastening member together with the nozzle body.
