Portable Air Inflator Cooling Duct Structure for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors used in portable air inflator devices suffer from poor heat dissipation due to their compact design, leading to reduced motor efficiency and potential damage from high temperatures, which shortens their service life.
Innovation Solution
An air guiding mechanism is integrated into the accommodation box to frame a cooling fan that rotates with the motor, guiding external air to dissipate heat efficiently and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the air compressor is made compact and portable, then portability is improved, but heat dissipation deteriorates
Solution Approach 1:
The air guiding mechanism utilizes three-dimensional space within the accommodation box by forming air guiding channels on the cap and case surfaces, directing air flow from multiple directions (front, rear, left, right) to the air compressor. This multi-dimensional air intake approach maximizes cooling efficiency within the compact portable form factor.
2Stability of the object's composition
If the air compressor is fixed in the accommodation box using multiple limitation bars or a fixing plate, then stability is improved, but heat dissipation deteriorates
Solution Approach 1:
The air guiding mechanism is segmented into multiple independent air guiding channels formed on different surfaces of the cap and case. These channels are distributed at different locations and orientations, allowing air to reach the air compressor from multiple directions simultaneously, thereby enhancing cooling without interfering with the fixing structure.
3Device complexity
If the cooling fan is not framed, then device complexity is reduced, but safety deteriorates due to risk of strike
Solution Approach 1:
The air guiding mechanism is integrally formed with the cap and case structures, merging the protective framing function with the air guiding function. The air guiding channels serve dual purposes: directing cooling air to the compressor while simultaneously forming a protective frame around the cooling fan, eliminating the need for separate protective structures.

AI summary
An air inflator device contains: an accommodation box and an air compressor (9). The accommodation box includes a cap (1) and a case (2), and the air compressor (9) and an air guiding mechanism are received in the cap (1) and the case (2). The air guiding mechanism is configured to frame a cooling fan (91) which is rotatably with a motor (92) of the air compressor (9). A flowing orifice (5) is defined by a first directing portion (3) and a second directing portion (4), and a first semicircular cover (32) and a second semicircular cover (42) of the air guiding mechanism are configured to collect and guide air so that the cooling fan (91) rotates to guide the air to the air compressor (9), thus dissipating heat and prolonging a service life of the air compressor (9).
