Volatile Material Dispenser Regulating Plate Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volatile material dispensers suffer from leakage due to uneven gaps between the regulating and covering plates, leading to incomplete inhibition of dispensing in the closed position and inadequate control over dispensing rates, along with loose cartridge placement causing inconvenience.
Innovation Solution
A dispenser design featuring a regulating plate with concentrated bored and non-bored portions, allowing precise control through a larger travel distance, and a fixing element to secure the cartridge, with an arc-shaped guide slot and tab mechanism for precise alignment and rotation, reducing leakage passages and stabilizing the cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bores are distributed uniformly on the covering plate and regulating plate, then the structure is simple and easy to manufacture, but the gap between bores creates multiple leakage passages that prevent sufficient inhibition of volatile material dispensing in closed position
Solution Approach 1:
The plate surface is segmented into distinct bored portions and non-bored portions. The non-bored portions create large covered areas that substantially inhibit volatile material dispensing when in closed position, while the bored portions provide controlled dispensing pathways when aligned.
Solution Approach 2:
Different portions of the plate have different properties: bored portions allow volatile material passage while non-bored portions provide sealing and inhibition. This local differentiation enables the plate to perform both dispensing and inhibition functions effectively.
2Length of moving object
If the travel distance between open and closed position is short, then the device structure is compact, but the dispensing control precision is insufficient
Solution Approach 1:
The regulating plate is designed to rotate between open and closed positions, creating a dynamic control mechanism. The rotation allows progressive alignment or misalignment of bored portions with the covering plate, enabling fine-tuned control over dispensing rates through intermediate positions.
3Device complexity
If the cartridge is not firmly retained in the housing, then the device structure is simple, but the cartridge placement becomes loose causing user inconvenience
Solution Approach 1:
The cartridge is designed with self-retaining features including engagement protrusions that automatically mate with corresponding recesses in the housing. This self-service mechanism ensures firm retention without requiring additional active retention components or complex assembly steps.

AI summary
A volatile material dispenser (100) and its housing and cartridge (600; 700) are disclosed. The housing for the volatile material dispenser (100) comprises a bottom plate (200; 200′), a covering plate (300) and a chamber defined therebetween for receiving a cartridge (600; 700), and the housing further comprises a regulating plate (400) movably mounted to the covering plate (300). The covering plate (300) and the regulating plate (400) each have one bored portion and one non-bore portion. The bored portion (420) and the non-bore portion (410) of the regulating plate (400) each occupy a half of the regulating plate (400). The regulating plate (400) is movable between an open position and a closed position with respect to the covering plate (300). The bored portion (320) of the covering plate (300) is aligned with the bored portion (420) of the regulating plate (400) in the open position, and the bored portion (320) of the covering plate (300) is covered by the non-bore portion (410) of the regulating plate (400) in the closed position. The chamber is provided with a fixing element capable of fixing the cartridge (600; 700) in place. The advantages of the present invention lie in that the dispensing of the dispenser (100) can be controlled more precisely.
