Atomizing Apparatus Pump Liquid Ingress Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing apparatuses risk malfunction when liquid enters the casing body, potentially damaging the pump due to liquid flow, especially when a pump for generating compressed air is internal.
Innovation Solution
The atomizing apparatus is designed with a housing configuration that includes tubular bodies and a pump placement where the discharge hole of the pump is positioned closer to the top end, preventing liquid from reaching the pump by storing it at the bottom surface of the first tubular body, thus preventing liquid from entering the pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pump is disposed inside the casing body, then the structure is integrated and compact, but the liquid may enter the pump and cause malfunction
Solution Approach 1:
The housing is divided into multiple cavities (first cavity and second cavity) separated by partition walls. The pump is located in the first cavity while the liquid reservoir is in the second cavity, physically segmenting the liquid flow path from the pump to prevent liquid ingress while maintaining integrated structure.
Solution Approach 2:
A communication hole acts as an intermediary structure that allows compressed air to pass from the first cavity to the second cavity while the partition wall prevents liquid from reaching the pump. This intermediary design enables functional connection while blocking harmful liquid flow.
2Ease of operation
If the nozzle hole is disposed at the upper end of the casing body, then the compressed air can be discharged upward for atomization, but the liquid may enter through the nozzle hole and reach the pump
Solution Approach 1:
The housing is segmented into multiple cavities with partition walls that create separate flow paths. The nozzle hole in the upper end discharges compressed air upward for atomization, while the partition wall prevents liquid from traveling down the nozzle hole to reach the pump located in the lower first cavity.
Solution Approach 2:
The partition wall extends vertically from the lower end to the upper end of the housing, creating a three-dimensional barrier that blocks liquid flow paths while allowing compressed air to pass through communication holes. This vertical segmentation in the third dimension prevents liquid ingress while maintaining atomization function.

AI summary
An atomizing apparatus having a top surface and a bottom surface includes a first tubular body, a second tubular body, pumps, and an atomizing portion. The pumps are disposed in the first tubular body and have an intake hole and a discharge hole. The atomizing portion is configured to atomize a liquid supplied to the housing by a gas discharged through the discharge hole of one of the pumps. The first tubular body has a first cavity and a first communication hole that is in communication with the second tubular body. The second tubular body has a second cavity and a through-hole. The through-hole is in communication with the first communication hole. The atomizing portion is disposed at the through-hole. The first cavity is disposed at a position closer than the through-hole to the top surface.
