Solution Overview
Problem
The connection strength of snap locking structures in handheld cleaning appliances is weak, leading to poor reliability and a short service life of the connection between the main unit assembly and the dust cup assembly.
Innovation Solution
A handheld structure with a mounting base that includes a main unit connector and a dust cup connector, allowing for detachable connections between the main unit assembly, dust cup assembly, and mounting base, dispersing force and enhancing connection reliability through additional connection points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a snap locking structure is used to connect the main unit assembly and dust cup assembly, then the assembly and disassembly is simple and quick, but the connection strength is weak and reliability is poor
Solution Approach 1:
The connection structure is segmented into multiple independent locking mechanisms (first locking mechanism on the main unit assembly and second locking mechanism on the dust cup assembly) that work together to provide both ease of operation and high reliability through distributed locking points
Solution Approach 2:
The locking mechanisms are nested within the connector structures, with locking balls and locking grooves integrated into the main unit connector and dust cup connector respectively, allowing compact design while maintaining strong connection reliability
2Device complexity
If a snap locking structure is used to connect the main unit assembly and dust cup assembly, then the structure is simple, but the service life is short due to easy breakage after long-term stress
Solution Approach 1:
The connection structure is divided into multiple independent locking mechanisms that distribute mechanical stress across multiple points, preventing any single point from bearing excessive load and failing prematurely
Solution Approach 2:
The locking mechanisms include elastic elements and cushioning structures that absorb and dissipate impact forces before they can damage the connection components, extending the service life under long-term stress conditions
3Device complexity
If only a snap locking structure is used for connection, then the structure is compact, but the connection strength is insufficient under long-term stress
Solution Approach 1:
The connection is strengthened by segmenting it into multiple locking mechanisms (first locking mechanism with locking ball and locking groove on main unit, second locking mechanism with locking ball and locking groove on dust cup) that work simultaneously to provide distributed strength
Solution Approach 2:
Multiple locking mechanisms are merged into a coordinated system where the first locking mechanism on the main unit assembly and the second locking mechanism on the dust cup assembly work together to provide enhanced connection strength while maintaining compact design

AI summary
The present application relates to the technical field of electrical cleaning appliances for household use, and in particular, to a handheld structure. The handheld structure provided by the present application comprises a mounting base (100), a main unit assembly (200) and a dust cup assembly (300) detachably connected to the main unit assembly. The mounting base comprises a mounting base body, a main unit connector (110) and a dust cup connector (120). The main unit connector and the dust cup connector are both connected to the mounting base body. The main unit assembly is detachably connected to the main unit connector. The dust cup assembly is detachably connected to the dust cup connector. The handheld structure, by providing a mounting base having a main unit connector and a dust cup connector, realizes further connection between the main unit assembly and the dust cup assembly through the mounting base, which reduces direct stress on the main unit assembly and the dust cup assembly, thus improves the reliability of connection between the main unit assembly and the dust cup assembly.
