Description

Vacuum cleaner

Technical field

This application relates to a vacuum cleaner, for example, to the waterproof design of the vacuum cleaner.

Background technique

The vacuum cleaner is a widely used cleaning tool. The head of the vacuum cleaner is usually equipped with a switch assembly. The switch assembly can be used to control the opening and closing of the vacuum cleaner motor. The switch assembly is usually provided with a switch cover exposed from the housing of the head. When encountering water, the water will enter the machine head from the gap between the switch cover and the shell of the machine head. The incoming water is basically uncontrolled and guided during the downward flow, and there is a greater chance of contacting the machine head. The internal electronic components will cause short circuit, leakage, electronic component damage and other safety hazards, and it will also make it difficult for the vacuum cleaner to pass the water spray test; for waterproofing, you can choose to add flexible sealing elements (such as sealing rings, sealing sleeves) and strengthening the periphery of the switch assembly. The matching accuracy of the switch cover and the machine head shell reduces the gap, but as the use time increases, the sealing element will be significantly reduced due to aging, and the matching accuracy of the switch cover and the machine head shell will also decrease, resulting in a decrease in waterproof performance , Causing greater safety hazards.
