Disinfection Atomiser Housing Cooling Ribs and Labyrinth Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfection apparatuses face challenges in protecting temperature-sensitive and corrosive disinfectants like hypochlorous acid from high temperatures and corrosive environments, leading to potential damage to sensitive components and inefficient disinfection processes.
Innovation Solution
The apparatus incorporates a rotatable bell cup with a hollow drive shaft and a housing featuring cooling ribs for temperature regulation and a contactless labyrinth seal to prevent liquid penetration, along with a ring structure for noise reduction and efficient gas flow, ensuring effective disinfection while protecting internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive unit is enclosed in a housing to protect components, then component protection is improved, but heat dissipation deteriorates
Solution Approach 1:
The housing is designed with cooling ribs that create thin film pathways for heat dissipation while maintaining the enclosed protective structure. The cooling ribs form a network of thin thermal pathways that allow heat to escape from the drive unit without compromising the protective enclosure.
2Reliability
If a contact seal is used to prevent liquid penetration into the housing, then sealing effectiveness is improved, but mechanical wear and corrosion resistance deteriorate
Solution Approach 1:
The patent replaces the mechanical contact seal with a magnetic coupling system. The drive shaft is magnetically coupled to the bell cup through the housing wall, eliminating the need for physical seals that contact corrosive liquids. This substitution of mechanical sealing with magnetic field coupling resolves the contradiction between sealing effectiveness and corrosion resistance.
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
The solution effectively dissipates heat, prevents corrosive liquid ingress, and ensures efficient disinfection, maintaining suitable temperatures for the disinfectant and protecting sensitive components, thereby enhancing the disinfection process's effectiveness and longevity.
Implementation Method 1
the housing has a plurality of cooling ribs (for example, heat ribs or cooling fins) and can thus preferably function as a heat exchanger. In particular, this allows heat to be effectively dissipated from the interior of the housing to the outside
Implementation Method 2
the drive shaft is provided with a (in particular contactless) labyrinth seal, for example in order to prevent unwanted penetration of liquid such as disinfectant and/or rinsing agent (but also room humidity, for example) into the housing
