Ultrasonic Liquid Sprayer Core Contact and Detachable Lid Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transducer-type liquid sprayers face issues with solid components and impurities accumulating in the storage tank, making it difficult to replace the liquid storage tank and core, which affects the sprayer's performance over time.
Innovation Solution
A liquid sprayer design featuring a spray liquid storage unit with a core that soaks up liquid externally and a main body with a lid member that can be easily opened and closed, allowing for easy detachment and replacement of the storage unit, where the transducer is fixed to a support arm and in close contact with the core's front face, facilitating easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid storage tank is detached from the liquid retaining body and only the storage tank is attached and detached to add spray liquid, then the spray liquid can be refilled, but solid components and impurities accumulate in the liquid retaining body over time making it unable to absorb spray liquid effectively
Solution Approach 1:
The liquid retaining body is segmented into multiple detachable cores that can be individually removed and replaced. Each core is a separate absorbent component that can be independently maintained, allowing users to replace only the saturated core rather than the entire liquid retaining body, thus maintaining absorption effectiveness while keeping the system simple to refill.
2Volume of moving object
If the liquid retaining body is housed in an L-shaped casing, then the structure is compact, but the liquid retaining body is difficult to detach from the casing and is not easy to replace
Solution Approach 1:
The liquid retaining body is divided into multiple separate cores that can be individually accessed and removed through the casing opening. This segmentation allows each core to be detached independently without requiring removal of the entire L-shaped casing, maintaining compact housing while enabling easy replacement of individual absorbent components.
Solution Approach 2:
The cores are designed to be extractable from the L-shaped casing through a dedicated opening. The cores can be removed individually from the casing without dismantling the casing structure itself, allowing easy replacement of the absorbent material while maintaining the compact housing design.
3Reliability
If the transducer is fixed to the core, then the transducer maintains contact with the core, but the transducer cannot be easily detached for maintenance when the lid is opened
Solution Approach 1:
The system is segmented into distinct functional modules: the core (absorbent component), the transducer (ultrasonic component), and the lid assembly. The transducer is mounted on the lid assembly rather than being fixed to the core, allowing independent access to each component. This modular segmentation enables easy detachment of the transducer for maintenance while ensuring reliable contact with the core during operation through the pressing mechanism in the lid.
Solution Approach 2:
The lid assembly incorporates a pressing mechanism that dynamically maintains contact between the transducer and the core. When the lid is closed, the pressing mechanism applies force to ensure the transducer remains in contact with the core for effective operation. When the lid is opened for maintenance, the contact is naturally released, allowing easy detachment of the transducer without permanent fixation.
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 easy replacement of the spray liquid storage unit and core, preventing accumulation of impurities and maintaining sprayer efficiency over long-term use by ensuring the transducer remains in contact with the core when the lid is closed and can be easily detached for maintenance.
Implementation Method 1
a core for soaking up spray liquid stored in a storage tank to an outside of the storage tank
Implementation Method 2
a transducer disposed inside the lid member, and the transducer disposed inside the lid member is in close contact with and pressed against the front face of the core

AI summary
A liquid sprayer (1) comprising a spray liquid storage unit (5) and a main body for supporting the spray liquid storage unit inside itself. The spray liquid storage unit includes a core (34) for soaking up spray liquid stored in a storage tank to an outside of the storage tank. The main body includes a lid member (2) to be put on a support member (3) for supporting the spray liquid storage unit so that the lid member can be opened and closed. A spray hole (8) is formed in a position of the lid member facing a front face of the core of the spray liquid storage unit supported by the support member when the lid member is closed onto the support member, a transducer (44) facing the spray hole is disposed inside the lid member, and the transducer disposed inside the lid member is in close contact with and pressed against the front face of the core of the spray liquid storage unit supported by the support member when the lid member is closed onto the support member.
