Humidifier Float Detection for Water Level and Tank Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidifiers require separate and expensive detection devices for water level and tank separation, leading to complex structures and increased costs.
Innovation Solution
A humidifier design incorporating a single detection device that utilizes a float movable within a preset space to indicate water tank separation and water level, using magnetic sensors to detect the float's position, reducing the need for multiple detection apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate detection devices are used for water level and tank separation detection, then detection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines water level detection and tank separation detection into a single integrated detection device. The detection device includes a detection component that can detect both the water level in the water tank and whether the water tank is separated from the pedestal, eliminating the need for separate detection devices and reducing overall system complexity while maintaining detection reliability
Solution Approach 2:
The detection device is designed with multi-functional capability to perform both water level detection and tank separation detection using the same hardware components. The detection component can identify different states (water level height and tank attachment status) through a single unified detection mechanism, making the system more versatile and cost-effective
2Measurement precision
If separate detection devices are used for water level and tank separation detection, then detection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges water level detection and tank separation detection into one integrated detection device, reducing the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while the detection component maintains sufficient accuracy for both detection functions through its multi-functional design
3Reliability
If multiple detection apparatuses are used, then detection coverage is improved, but energy consumption increases
Solution Approach 1:
The patent combines multiple detection functions into a single detection device that operates as one integrated system. This unified detection apparatus consumes less energy compared to multiple separate detection devices, as it shares common power supply, signal processing, and control resources while still providing comprehensive detection coverage for both water level and tank separation status

AI summary
A humidifier includes a pedestal, a water tank, a float, and a detection device. The water tank is detachably mounted on a top of the pedestal. The float is on the water tank and movable relative to the water tank. The detection device is on the pedestal and configured to detect a position of the float in a preset space of the humidifier. In the preset space, the position of the float indicates whether the water tank is separated from the pedestal and whether the water tank is short of water.
