Atomizing Sprayer Porous Plate Fixation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers lack a secure mechanism to firmly fix the nozzle or porous plate, risking it from dropping off and being accidentally aspirated by the user, which compromises safety.
Innovation Solution
The atomizing sprayer structure includes a vapor tube, front and rear washers, an ultrasonic chip, a porous plate holder, and a porous plate, where the assembly is fixed by protrusion rings to prevent the porous plate from falling out, with the inner diameter of the spray hole being smaller than the plate to enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the nozzle plate is attached to the plate holder by gel, then the assembly process is simple, but the nozzle plate may drop off and be accidentally aspirated by the user
Solution Approach 1:
The front washer is divided into two functional parts: an outer protrusion ring for securing the plate holder and an inner protrusion ring for securing the porous plate. This segmentation allows each component to be firmly fixed at its designated position, preventing the porous plate from dropping off while maintaining a relatively simple assembly process through the washer's integrated design.
Solution Approach 2:
The solution transitions from a single-dimensional gel attachment to a multi-dimensional mechanical constraint system. The front washer provides radial constraint through its protrusion rings, while the vapor tube's spray hole provides axial constraint, creating a three-dimensional fixation structure that securely holds the porous plate in place.
2Device complexity
If the structure is simplified to reduce complexity, then manufacturing is easier, but the safety mechanism to prevent component dropping is insufficient
Solution Approach 1:
The front washer serves multiple functions: it acts as a sealing element, a structural support, and a fixing mechanism through its dual protrusion rings. The vapor tube also serves dual purposes as both the atomization chamber and a safety barrier. This multi-functionality reduces the need for additional separate safety components, maintaining structural simplicity while ensuring safety.
Solution Approach 2:
The design incorporates preventive safety measures in advance: the inner protrusion ring of the front washer and the vapor tube's spray hole are designed to prevent the porous plate from dropping before any accident can occur. This proactive approach eliminates the need for complex post-failure safety mechanisms.

AI summary
An atomizing sprayer includes a vapor tube, a front washer, an ultrasonic chip, a porous plate holder, a porous plate, a rear washer, and a chip holder. The chip holder has an opening hole at its center. One side of the chip holder has an accommodating space and a circular groove. The rear washer is disposed in the circular groove and its outer surface leans against the edge of the central hole of the ultrasonic chip. The porous plate holder is disposed on the ultrasonic chip and the porous plate is disposed on the porous plate holder. The outer protrusion ring of the front washer leans against the porous plate holder and the inner protrusion ring of the front washer leans against the porous plate, so the assembly of the ultrasonic chip, the porous plate holder and the porous plate can be fixed between the front and rear washers.
