Humidifier Valve Design to Prevent Liquid Dripping During Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of liquid dripping onto the ground or table when the main unit of a humidifier is detached from the water tank, causing user inconvenience and contamination.
Innovation Solution
A humidifier design featuring a rim surrounding the water filling opening and a valve on the main unit that closes the overflow port when detached, preventing liquid overflow and ensuring the liquid flows into the water tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the main unit is detachably mounted on the water tank, then cleaning and maintenance are facilitated, but liquid drips onto the ground or table during removal
Solution Approach 1:
The valve is pre-positioned on the overflow port before detachment occurs. When the main unit is removed from the water tank, the valve automatically closes to seal the overflow port, preventing liquid from dripping outward. This preliminary preparation of the sealing mechanism resolves the contradiction by enabling easy detachment while preventing harmful liquid leakage.
Solution Approach 2:
The valve acts as an intermediary element between the overflow port and the external environment. During detachment, the valve closes to mediate the liquid flow, redirecting it away from the detachment path and preventing it from reaching the ground or table. This intermediary mechanism allows both easy maintenance access and prevention of liquid contamination.
2Quantity of substance
If the overflow port remains open during detachment, then liquid can flow into the water tank, but liquid may drip outside the humidifier
Solution Approach 1:
The valve transitions from an open state during normal operation to a closed state during detachment. This dynamic adjustment allows the system to adapt its liquid flow characteristics based on operational conditions - permitting liquid flow into the water tank during use, but sealing the overflow port during removal to prevent external dripping. The dynamic valve state resolves the contradiction between maintaining liquid flow paths and preventing harmful leakage.

AI summary
The present application belongs to the technical field of humidification devices which includes a detachably connected main unit and a water tank. An atomizing chamber is formed in the main unit, with a water inlet and an overflow port in the atomizing chamber. The atomizing chamber has a with a rim that surrounds the water inlet. Both the overflow port and the water inlet are connected to the water tank. A water stop valve is provided on the main unit which is used to close the overflow port when the main unit is detached from the water tank. Besides normal operation, the humidifier is capable of preventing the liquid to be atomized from dripping onto objects such as the ground or table after the main unit is detached from the water tank, thereby improving the user experience.
