[0002] Vacuum cleaners are important household appliances that help clean the floor at home. The invention of vacuum cleaners has brought great convenience to family life. Vacuum cleaners are divided into corded vacuum cleaners and cordless vacuum cleaners. The working principle of corded vacuum cleaners is that the vacuum cleaner motor rotates at high speed, sucking air from the suction port to create a certain vacuum in the dust box, thereby cleaning the dust. Corded vacuum cleaners have relatively strong suction power, but because of the rope, it is inconvenient to clean in some places, but the price is cheap and the quality is good, so corded vacuum cleaners are very popular.

[0003] However, current vacuum cleaners lack necessary protective devices. Since corded vacuum cleaners have great suction force, when the suction port is blocked by foreign objects, the air pump does not stop working. The strong suction force can easily cause damage to the equipment, thereby greatly reducing the service life of the vacuum cleaner. Therefore, those skilled in the art provide a corded vacuum cleaner with a protective device to solve the problems raised in the above background technology. Utility Model Content
