Do you have any sweaters at home? I think you must promise. Every household has sweaters now, but have you ever observed sweaters? If you look carefully, you will find that there are many small balls on the sweater, which are made up of the hairs on the sweater. This will not only hinder the appearance, but also make you feel very uncomfortable. If it is not handled properly, it will damage the whole sweater, which is even worse. At this time, it's the hair ball trimmer's turn to play. I saw it running at full power, blowing hairballs. I saw that all the hairballs were gone and the sweater was clean. Just when I was surprised by this hairball trimmer, a cloud of doubt suddenly rose. How to trim the fluff trimmer?

While I was wondering, my father spoke and asked me to find the answer myself.

I took out the instructions, studied them carefully and began to dismantle the trimmer. I turned off the switch of the repairer first, then unscrewed and pulled out the outermost outer knife net, and then took out the main round knife. The blade was extremely sharp, and then I saw the wind blade with four boards erected. When the switch is turned on, it will turn quickly. There is a huge gap at the bottom of the fan blade, and the hair ball falls from this gap and falls into the storage bin, where it is kept.

It turns out that this trimmer uses a motor to drive the blade to rotate, and the blade is connected with a round knife. When the blade rotates at high speed, so does the circular knife. The outer knife net separates the clothes from the round knife to prevent direct contact with the clothes. There are many small holes in the outer cutter net. When the hair ball contacts the clothes, the hair ball extends into the outer knife net and is directly cut by the circular knife. The cut hair ball fell from the side of the round knife to the fan blade below. In the case of high-speed rotation, the four vertical plates on the blade "hit" the hair balls into the storage bin like playing badminton. During the experiment, I found a problem: as soon as I unscrewed the outer knife net, the maintainer stopped rotating. Is there no electricity? Then why did you turn so fast just now? After many experiments, I found that there is a button next to the fan blade, just like the lamp on the refrigerator, there is a button. This button will be pressed after the outer cutter net is tightened. When pressed to the bottom, the protection function is turned off and the trimmer works normally.

It turns out that a hairball trimmer still has so much knowledge!
