Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic humidifiers have complex humidification flow paths, leading to difficulties in supplying mist evenly to indoor spaces, potential contamination due to unsterilized water, and challenging cleaning processes, which affects their efficiency and sanitary performance.
Innovation Solution
A humidifier design featuring a simplified structure with a blower fan creating an ascending air stream, a diversion guide to separate the air stream, and a cylindrical humidification reservoir with annular discharge paths, allowing mist to rise and be distributed uniformly, along with a heating reservoir for sterilizing water, facilitating easy cleaning and improved sanitary performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex humidification flow path is used to create a flow of humidified air, then the humidification function is achieved, but the structural design becomes complex and cleaning becomes difficult
Solution Approach 1:
The humidifier is divided into functionally independent modules: an ultrasonic atomization module for mist generation, a heating module for water sterilization, and a simple discharge structure. This segmentation allows each module to perform its function independently without requiring complex flow paths, thereby simplifying the overall structure while maintaining humidification effectiveness.
2Reliability
If a complex humidification flow path is used, then humidified air flow is created, but the air stream forms eddy currents and mist supply becomes uneven
Solution Approach 1:
The patent extracts the essential function of humidification from the complex flow path by using ultrasonic vibration to directly atomize water into mist that rises naturally. The heating element sterilizes water before atomization, and the simplified discharge structure allows mist to be supplied uniformly without eddy currents, thereby improving mist supply efficiency while maintaining reliable humidified air flow.
3Productivity
If water is atomized immediately without sterilization, then humidification is achieved quickly, but contamination occurs and health risks arise
Solution Approach 1:
The patent applies preliminary sterilization by heating the water before ultrasonic atomization. This preliminary action eliminates potential contaminants and pathogens in the water, ensuring that the mist generated is clean and safe for indoor use, while the subsequent rapid atomization maintains efficient humidification speed.
4Ease of operation
If a simplified structure is used, then ease of cleaning is improved, but mist distribution uniformity may be compromised
Solution Approach 1:
The simplified discharge structure allows mist to rise and distribute uniformly through natural convection and the inherent geometry of the discharge opening, without requiring complex flow control mechanisms. This self-service approach maintains mist distribution uniformity while maximizing ease of cleaning through the absence of complex internal passages.

AI summary
The present disclosure relates to a humidifier. A humidifier of the present disclosure includes: a case having an inlet and a outlet with an open top; a humidification reservoir disposed inside the case, that produces mist and has an open top so that the produced mist rises therethrough; a guide wall disposed above the humidification reservoir, that is spaced inward from the case and extends upward; a blower fan disposed below the humidification reservoir, that creates an ascending air stream within the case; and a diversion guide disposed on the top of the humidification reservoir, that divides the ascending air stream, wherein a blower flow path is formed between the humidification reservoir and the case, through which the ascending air stream flows, an inner discharge flow path is formed inside the guide wall, through which the mist produced in the humidification reservoir and part of the ascending air stream that has passed through the blower flow path flow, an outer discharge flow path is formed between the guide wall and the case, through which the rest of the ascending air stream that has passed through the blower flow path flows, and the diversion guide guides part of the ascending air stream that has passed through the blower flow path to the inner discharge flow path.
