Blowing suction device
Solution Overview
Problem
Existing blowing suction devices require detachment and reassembly of blowing and suction tubes for mode switching, leading to complex operations and inconvenient human-machine interaction.
Innovation Solution
A single-tube blowing suction device with a pivotally disposed volute that rotates between blowing and suction modes, allowing airflow to flow through the same tube for both functions without detachment, utilizing a motor-driven fan and volute with air inlet and outlet portions for efficient airflow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blowing tube and suction tube are detached and assembled alternately for mode switching, then blowing and suction functions can be implemented, but operation complexity increases and human-machine interaction becomes inconvenient
Solution Approach 1:
The patent applies a single tube that serves both blowing and suction functions by rotating the volute to change airflow direction. The same tube is used for both modes, eliminating the need for separate tubes and detachment operations, thus improving ease of operation while maintaining adaptability.
Solution Approach 2:
The volute is designed to be rotatable relative to the tube, allowing dynamic switching between blowing and suction modes by changing the orientation of the airflow generation apparatus. This dynamic adjustment enables mode switching without tube detachment, resolving the contradiction between versatility and ease of operation.
2Adaptability or versatility
If blowing tube and suction tube are detached and assembled alternately, then mode switching is achieved, but time is lost during detachment and reassembly
Solution Approach 1:
The tube is pre-configured to work with both blowing and suction modes through the rotatable volute design. The airflow generation apparatus can be rotated to different positions (blowing position and suction position) without requiring tube detachment, thus eliminating time loss while maintaining mode switching capability.
Solution Approach 2:
The rotatable volute mechanism allows quick switching between modes by simply rotating the airflow generation apparatus to different angular positions, eliminating the time-consuming detachment and reassembly process while preserving adaptability.
3Ease of operation
If a single tube is used for both blowing and suction, then operation is simplified, but airflow management becomes more challenging
Solution Approach 1:
The volute is designed to be rotatable, allowing the airflow generation apparatus to be positioned at different angles. When rotated to the blowing position, airflow flows into the tube for blowing operation. When rotated to the suction position, airflow direction changes for suction operation. This dynamic repositioning manages airflow effectively while maintaining a single tube configuration, thus simplifying operation without excessive complexity.
Solution Approach 2:
The airflow path is segmented into different flow channels within the volute structure, with separate air inlet portions and air outlet portions that can be selectively connected to the tube. This internal segmentation allows effective airflow management for both modes while maintaining a single external tube interface.

AI summary
A single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion of the airflow generation apparatus is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.
