Suction Port Body For Electric Vacuum Cleaner, And Electric Vacuum Cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suction port designs for electric vacuum cleaners with upwardly protruding curved shapes obstruct downsizing due to the placement of illuminating parts, which hinder compactification while maintaining a light source functionality.
Innovation Solution
A suction port body design featuring a case body with a curve-shaped portion that protrudes upward, incorporating a light source positioned at the rear of the top portion and in front of the pipe portion, allowing the light source to utilize the space between the curve-shaped portion and the pipe, thus enabling downsizing while maintaining illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is provided at the top portion of the curve-shaped portion or in front of the curve-shaped portion, then the illumination function is achieved, but the floor suction tool cannot be downsized
Solution Approach 1:
The light source is positioned in the depth direction (front-rear dimension) of the curve-shaped portion rather than at the top or front surface, utilizing the third dimension to achieve compact integration while maintaining illumination functionality
Solution Approach 2:
The light source is nested within the space formed by the curve-shaped portion and the pipe portion, effectively using the existing structural volume to accommodate the illumination component without increasing overall device size

AI summary
The present invention has an object to achieve a suction port body for an electric vacuum cleaner, which can be downsized while including a light source, and an electric vacuum cleaner including the suction port body. The suction port body (100) includes: a case body (110) having a curve-shaped portion (126) being curved so as to protrude upward and a suction port (120) in a bottom surface; a pipe portion (150) that is provided at rear of the curve-shaped portion (126) and is configured to allow communication between a suction source and the suction port (120); and a light source (210) arranged so as to radiate light to a front side of the case body (110). The light source (210) is located in front of the pipe portion (150) and at rear of a top portion of the curve-shaped portion (126).
