The production process of cordless vacuum cleaners mainly includes the following key steps:
Design stage: First, the designer will make a detailed design according to the product requirements, including planning in terms of appearance, function, performance, etc. This stage needs to determine the design scheme of key components such as the overall structure of the vacuum cleaner, motor, battery, control system, etc.
Parts production and assembly:
Motor: The motor of the cordless vacuum cleaner is its core component, responsible for providing suction and power. Modern cordless vacuum cleaners usually use brushless motors to improve efficiency and life. For example, Lake Electric's high-power motor uses a 500W high-suction wet and dry magnesium-aluminum alloy motor with an efficiency of more than 50%.
Battery: The battery is the power source of the cordless vacuum cleaner, usually lithium batteries. The capacity and charging speed of the battery directly affect the endurance of the product. In order to improve energy efficiency, an efficient battery management system (BMS) can be used to optimize the use of the battery.
Control system: Including circuit boards, switching devices, etc., responsible for controlling the start, stop and various function adjustments of the motor. For example, Toshiba's U-MOS series MOSFET has low on-resistance and high-speed switching characteristics, which can effectively reduce power loss and improve motor drive efficiency.
Other components: Such as dust cups, filters, suction heads, etc., the design and manufacture of these components also require fine craftsmanship to ensure the performance and durability of the vacuum cleaner.
Assembly and testing: After the production of parts is completed, assembly is carried out. The assembly process needs to ensure the precise fit and firm connection of each component. After assembly, functional tests and performance tests are carried out to ensure that the performance of the vacuum cleaner in various usage scenarios meets the design requirements.
Quality control and packaging: After all tests are completed, quality control checks are carried out to ensure that the product is free of defects. It is then packaged for transportation and sales.
Through the above steps, every link of the cordless vacuum cleaner from design to production is carefully designed and strictly quality controlled to ensure the performance and quality of the final product.
