Humidifier with regular addition of fixed quantity of essential oil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional humidifiers require the replacement of the entire peristaltic pump when switching between different essential oil bottles, and the flexible tube cannot be replaced separately, leading to mixing of fragrances and increased costs.
Innovation Solution
A humidifier design with a separate essential oil bottle accommodation space and a peristaltic pump head that allows for the independent replacement of essential oil bottles without replacing the peristaltic pump, and a liquid delivering hose that prevents fragrance mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional humidifier uses a peristaltic pump for essential oil delivery, then the essential oil can be delivered regularly, but the entire peristaltic pump must be replaced when switching between different essential oil bottles, increasing cost and complexity
Solution Approach 1:
The peristaltic pump is segmented into two independent parts: the pump body (fixed in the humidifier) and the pump head (attached to the essential oil bottle). When switching essential oils, only the pump head and bottle need to be replaced, not the entire pump. This segmentation reduces replacement complexity and cost while maintaining reliable essential oil delivery functionality.
2Ease of manufacture
If the flexible tube is fixed in the conventional humidifier, then the structure is simple, but the tube cannot be replaced together with different essential oils, causing fragrance mixing
Solution Approach 1:
The liquid delivering hose is integrated with the pump head as a single replaceable unit. When switching essential oils, the user removes the old pump head (with its hose) and attaches a new pump head with a fresh hose to the pump body. This segmentation allows the hose to be replaced simultaneously with the essential oil bottle, preventing fragrance mixing while keeping the overall structure simple and easy to manufacture.
3Device complexity
If the essential oil is dropped directly into the atomization reaction zone, then the structure is simple, but the essential oil volatilizes rapidly and fragrance duration is insufficient
Solution Approach 1:
The peristaltic pump performs preliminary action by delivering essential oil regularly and controllably into the atomization reaction zone, rather than allowing direct rapid volatilization. This controlled delivery ensures the essential oil is introduced at the optimal rate and timing, extending the duration of effective fragrance release while maintaining a relatively simple overall device structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cost-effective switching between essential oils without fragrance mixing, reducing user inconvenience and maintaining consistent scents by allowing independent replacement of essential oil bottles and peristaltic pump heads.
Implementation Method 1
a peristaltic pump head provided in the essential oil bottle accommodation space and driven by the peristaltic pump, in the peristaltic pump head is provided with a plurality of rollers driven by the transmission shaft
Implementation Method 2
an atomizing plate disposed within the temporary liquid storage basin
Implementation Method 3
a fan generating air stream within the atomizing space after being started
Implementation Method 4
a heating tube extending into the water storage bucket and heating the water stored in the water storage bucket

AI summary
A humidifier with regular addition of fixed quantity of essential oil has a main body, and a water storage bucket assembling with the main body. The main body has an opening located on one side, an inner casing corresponding to the opening, and a peristaltic pump provided on a side of the inner casing not facing the opening. The inner casing defines an essential oil bottle accommodation space communicating with the opening, and the essential oil bottle accommodation space is provided for disposing an essential oil bottle storing an essential oil. The peristaltic pump is controlled by the main body, thereby fixed quantity of essential oil is supplied regularly and quantitatively by the humidifier without dismounting the water storage bucket. Thus, fragrance is kept in atomizing air continuously to solve the problem of the conventional humidifier that fragrance merely exists when the essential oil is added initially.
