The vacuum cleaner has two cores, the main body and the hose reel, both of which are indispensable. The power spring is an accessory applied to the hose reel, and its main function is to assist the contraction of the hose reel. How does it do this? It is not difficult to see the clues from the characteristics of the power spring. It uses a spring box to limit its outer diameter, so that the center of the spring is connected to the power shaft. When the external force causes the shaft and the spring to rotate relative to each other, the spring will roll on the power shaft and store kinetic energy. When the external force disappears, the spring will The torque is generated to drive the power shaft, and then the kinetic energy stored by the spring is output through the power shaft to help the tube reel to contract freely.
Therefore, from the above characteristics, it is not difficult to see that the power spring has a great impact on the vacuum cleaner. A high-quality vacuum cleaner also needs high-quality spring support, which greatly enhances the practicability of the vacuum cleaner. It is not too much to say that it has worked hard and made great achievements.
