Humidifier having an adjustable spray angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidifiers with adjustable mist outlet angles face instability when high-speed airflow impacts the arc-shaped cover, leading to reduced spray angle stability and unsatisfied user requirements.
Innovation Solution
A humidifier with a rotatable spray assembly and adjustable grooves allows for precise adjustment and stabilization of the spray angle, ensuring enlarged spray area and improved user experience by using altering grooves and an adjustment member to secure the spray angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the spray angle is adjusted to enlarge the spray area, then the coverage area is improved, but the stability of the spray angle deteriorates under high-speed airflow impact
Solution Approach 1:
The spray assembly is designed to be rotatable relative to the humidifier body, allowing dynamic adjustment of the spray angle. The altering adjustment member can move between multiple altering grooves to change the spray angle according to different usage scenarios, enabling the system to adapt dynamically rather than being fixed
Solution Approach 2:
The altering adjustment member acts as an intermediary mechanism between the user's adjustment action and the spray assembly's angular position. It transmits the adjustment motion through the altering grooves to achieve stable angular positioning, mediating between the need for adjustability and the need for stability under airflow impact
2Length of moving object
If the airflow speed is increased to spray water mist to a further region, then the spray distance is improved, but the arc-shaped cover slides within the mist outlet cavity causing instability
Solution Approach 1:
The altering adjustment member serves as an intermediary that stabilizes the arc-shaped cover (or spray assembly) against the forces generated by high-speed airflow. By providing positive engagement through the altering grooves, it prevents the cover from sliding while still allowing for angular adjustment when needed
Solution Approach 2:
The instability problem is isolated to the interaction between the arc-shaped cover and the airflow. The solution extracts the stabilization function into a separate mechanism (the altering adjustment member engaging with altering grooves), allowing the cover to be stabilized independently from the airflow dynamics

AI summary
A humidifier includes a humidifier body and a spray assembly. The humidifier body has a mist outlet. The spray assembly has a spray outlet and is rotatably disposed on the humidifier body to enable adjustment of the angle of the spray outlet so that the spray area can be enlarged. Consequently, a user can adjust the spray angle according to the position of an object to be sprayed so that the function of adjusting the spray angle of the humidifier can be fulfilled. One of the spray assembly and the humidifier body has at least two altering grooves, and the other one of the spray assembly and the humidifier body is provided with an altering adjustment member. The altering adjustment member can move from one altering groove to another altering groove along the rotation direction of the spray assembly to alter the spray angle.
