Blower Handle Layout for Low-Loss Airflow Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers lack a separate handle for easy gripping and positioning, which interferes with air flow direction, reducing blowing performance and causing air flow loss.
Innovation Solution
A blower design with a handle positioned between the fan and air guide, allowing for easy transport and guiding air flow while minimizing air flow loss, featuring a handle that protrudes into the lower case and is inclined to direct air flow towards the discharge port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is provided on the blower, then ease of transport is improved, but air flow obstruction increases and blowing performance deteriorates
Solution Approach 1:
The handle is repositioned from the front discharge area to the rear suction area of the blower, utilizing the rear space that was previously underutilized. This spatial reconfiguration allows the handle to coexist with the air flow path, eliminating obstruction while maintaining transport functionality.
Solution Approach 2:
The handle is designed with an air flow guide structure that acts as an intermediary element. The guide directs air flow around the handle, allowing the handle to remain in position for easy transport while preventing it from obstructing the air flow path.
2Ease of operation
If the handle is disposed at a position for easy gripping, then ease of operation is improved, but air flow loss increases
Solution Approach 1:
The handle is positioned in the rear suction area rather than the front discharge area, utilizing a different spatial dimension that does not interfere with the primary air flow path. This repositioning eliminates air flow loss while maintaining gripping accessibility.
Solution Approach 2:
The air flow guide serves as an intermediary that mediates between the handle presence and air flow requirements. It channels air flow around the handle structure, preventing direct obstruction and minimizing energy loss.
3Ease of operation
If the handle protrudes into the lower case, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The handle structure is merged with the air flow guide function, combining two elements into one integrated component. This reduces overall device complexity while maintaining both the ease of operation and air flow guidance functions.
Solution Approach 2:
The handle serves multiple functions simultaneously: it provides gripping for transport, guides air flow, and structurally integrates with the lower case. This multi-functionality reduces the need for separate components, simplifying the overall device.
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
Facilitates the transport and improves blowing performance by ensuring the handle does not obstruct air flow, allowing for efficient air distribution and reduced flow loss.
Implementation Method 1
a fan disposed inside the lower case and blowing air introduced through the suction port upward
Implementation Method 2
an air guide disposed inside the first tower and spaced apart from a front end of the first tower and elongated along a front and rear direction toward the first discharge port, so that air blown from the fan may be guided to the first discharge port by the air guide
Implementation Method 3
a handle disposed between the fan and the air guide and elongated from upstream of the air guide toward the front end of the first tower, so that the blower may be easily transported, and simultaneously, air blown from the fan may be guided to the front end of the first tower

AI summary
The present disclosure relates to a blower. The blower according to an aspect of the present disclosure includes: a lower case in which a suction port is formed; a fan disposed inside the lower case and blowing air introduced through the suction port upward; a first tower elongated to an upper side from the lower case and formed with a first discharge port opening forward; a second tower spaced apart from the first tower in a horizontal direction, elongated to an upper side from the lower case, and formed with a second discharge port opening forward; an air guide disposed inside the first tower and spaced apart from a front end of the first tower and elongated along a front and rear direction toward the first discharge port; and a handle disposed between the fan and the air guide and elongated from upstream of the air guide toward the front end of the first tower. The handle is disposed between the fan and the air guide, so that the blowing performance of the blower can be enhanced.
