Dust collecting attachment for blower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust collected by blower systems can enter the motor, causing adverse effects, and existing solutions do not adequately address this issue.
Innovation Solution
A dust collecting attachment with a removable design that includes a filter and check valve, allowing air to flow while trapping dust in a storage space, preventing it from entering the blower's motor, and allowing for easy filter cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction nozzle is attached to the blower for dust collection, then dust can be collected and removed, but dust may enter the blower body and adversely affect the motor
Solution Approach 1:
A dust collecting attachment is introduced as an intermediary component between the suction nozzle and the blower body. This attachment includes a dust storage space that captures dust particles before they can enter the blower housing and reach the motor, thus protecting the motor while maintaining dust collection functionality
Solution Approach 2:
The dust collection system is segmented into distinct functional zones: the suction nozzle for capturing dust, the dust storage space for containing collected dust, and the blower body for air movement. This segmentation allows dust to be isolated in the storage space rather than being drawn into the motor area
2Reliability
If a dust storage space is added to the attachment body, then dust can be trapped before entering the blower, but the device complexity increases
Solution Approach 1:
The dust storage space is merged with the attachment body structure, combining the dust collection function and the storage function into a single integrated component. This reduces overall system complexity compared to having separate collection and storage systems
Solution Approach 2:
The attachment body serves multiple functions: it acts as the housing for the dust storage space, provides the structural interface for connecting to the blower, and contains the mechanisms for dust capture and storage. This multi-functionality reduces the need for additional separate components
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
Effectively reduces the risk of dust entering the blower's motor, maintaining efficiency and extending the lifespan of the blower by capturing dust before it can cause damage.
Implementation Method 1
a blower (a so-called air duster) that is configured to suck air through an inlet opening, compress the air and discharge compressed air through a nozzle, using a plurality of centrifugal fans
Implementation Method 2
The dust collecting attachment includes an attachment body. The attachment body has a first opening, a second opening, and a dust storage space between the first opening and the second opening

AI summary
A dust collecting attachment is configured to be removably attached to a blower. The blower includes a housing that has an inlet opening and a discharge opening, a motor that is within the housing, and a fan that is within the housing and is configured to be rotated by the motor to generate a flow of air that is sucked into the housing through the inlet opening and is discharged from the discharge opening via the motor. The dust collecting attachment includes an attachment body that has a first opening, a second opening, and a dust storage space between the first opening and the second opening. The attachment body is configured to be attached to the housing such that the second opening communicates with the inlet opening of the housing of the blower.
