[0002] Computers, commonly known as computers, are electronic computing machines used for high-speed computing. They can perform numerical and logical calculations, and also have storage and memory functions. They are modern intelligent electronic devices that can run according to programs and automatically and quickly process massive amounts of data. They are composed of hardware systems and software systems. Computers without any software installed are called bare metal computers. They can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. More advanced computers include biological computers, photonic computers, and quantum computers.

[0003] With the development of society and the advancement of science and technology, computers have long become an essential tool for people's production, study, and work, and computers have been widely used in every household. Moreover, the size of computers is getting smaller and smaller, especially laptops and tablets are becoming more and more popular. The main components of computers are various electronic components. When the computer is in use, a large amount of static electricity is generated, and dust is easily accumulated on the surface. A large amount of heat is generated when working. Since dust covers the electronic components, it blocks the heat dissipation of the electronic components. The heat gathers together, which not only easily causes the electronic components to age, but also easily causes the computer to freeze and heat up when in use, seriously affecting the user experience. Therefore, the keyboard, display, etc. of the computer need to be cleaned regularly to remove the dust accumulated on them. Utility Model Content
