Abstract:As a convenient tool for household cleaning, the working current of the cordless vacuum cleaner is related to the performance and battery life of the product.
This article will make a detailed analysis of the working principle of cordless vacuum cleaners, the factors that affect the working current, and the working current of common products on the market.
First, the working principle of the cordless vacuum cleaner
Cordless vacuum cleaners are mainly composed of motors, batteries, filter systems, nozzles, and other components.
It works by supplying electrical energy to the motor through the battery, driving the motor to rotate and generate negative pressure, which inhales dust and debris.
Compared with corded vacuum cleaners, cordless vacuum cleaners are free from the shackles of power cords and are more convenient to use.
2. Factors affecting the working current of the cordless vacuum cleaner
1. Battery capacity: The larger the battery capacity, the greater the current it can provide, which makes the vacuum cleaner work longer and the performance more stable.
2. Motor type: There are two main types of motors for wireless vacuum cleaners: DC brushless motor and AC motor.
The brushless DC motor has the characteristics of high efficiency, low noise and low power consumption, and the working current is relatively small, while the working current of the AC motor is larger.
3. Suction power: The greater the suction power, the more electric energy the motor needs to consume, and the larger the working current.
4. Use time: Long-term use will cause the battery capacity to decrease and the working current to increase.
5. Product design: Reasonable product design can reduce the circuit impedance and reduce the working current.
3. The working current of common cordless vacuum cleaners on the market
According to market research, the working current of cordless vacuum cleaners on the market is roughly between 1-2.5A.
For example, a well-known brand of cordless vacuum cleaner has an operating current of 1.5A and a battery capacity of 21.6V, which can provide about 30 minutes of use.
Fourth, how to choose the right cordless vacuum cleaner
1. Choose products with suitable battery capacity and suction power according to household needs.
2. Pay attention to the type of motor, and give preference to the products of brushless DC motors.
3. Consider the use time of the product and choose a product with strong battery life.
4. Pay attention to product design, choose products with small circuit impedance and small working current.
5. Summary
The operating current of the cordless vacuum cleaner directly affects the performance and battery life of the product.
When purchasing, consumers should pay attention to factors such as battery capacity, motor type, suction power, use time, and product design to choose the right product.
At present, the working current of cordless vacuum cleaners on the market is roughly between 1-2.5A, and consumers can choose according to their needs and budget.
