Atomizer Battery Microphone Venting Against Condensate Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices face issues with external liquid and condensate splashing into the microphone air outlet hole, leading to blockage and potential damage due to moisture, which affects the microphone's ability to control atomization operations.
Innovation Solution
The device incorporates an air guiding structure with a through hole and a blocking portion to redirect the microphone air outlet hole away from the mounting groove opening, utilizing a diameter less than 0.4mm to prevent liquid entry, and includes an oil storage groove to collect excess liquid, ensuring the microphone remains dry and functional.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the microphone air outlet hole is directly arranged at the groove bottom of the mounting groove, then the microphone can better sense the change of air pressure, but external liquid and condensate can directly splash into the microphone air outlet hole causing blockage and damage
Solution Approach 1:
The patent divides the air outlet structure into multiple segments: the original microphone air outlet hole in the mounting groove bottom is separated from the new air outlet hole in the groove side wall by introducing an air guiding structure. This segmentation allows the microphone to maintain its original sensing function while the new air outlet provides liquid protection, resolving the contradiction between sensing capability and liquid protection.
Solution Approach 2:
The air guiding structure serves as an intermediary element between the microphone air outlet hole and the external environment. It redirects the air outlet function from the groove bottom to the groove side wall, allowing air to reach the microphone while preventing direct liquid contact. This intermediary structure resolves the contradiction by mediating between the need for air pressure sensing and protection from liquid splashing.
2Productivity
If the microphone air outlet hole is positioned to face the groove opening, then air flow is unobstructed, but liquid can easily enter and block the hole
Solution Approach 1:
The patent changes the spatial dimension of the air outlet from the vertical groove bottom (facing upward toward the groove opening) to the horizontal groove side wall (facing laterally). This dimensional change allows air to flow through the side wall opening without creating a direct path for liquid to enter from above, thus maintaining air flow efficiency while reducing liquid blockage risk.
Solution Approach 2:
The air outlet function is extracted from the groove bottom location and relocated to the groove side wall through the air guiding structure. This extraction separates the air flow function from the location vulnerable to liquid splashing, allowing the air outlet to maintain unobstructed flow while being positioned in a location less susceptible to liquid entry.
3Reliability
If a small diameter through hole is used in the air guiding structure, then liquid entry is prevented, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a particular parameter range for the through hole diameter (less than or equal to 0.4mm) to optimize the balance between liquid prevention and manufacturing feasibility. This parameter change establishes a specific size threshold that is small enough to prevent liquid entry through surface tension effects while remaining manufacturable with standard precision capabilities, thus resolving the contradiction between reliability and manufacturing precision.
