Description

Technical Field

[0001] The present disclosure relates to an electronic product. Background Art

[0002] Existing laptops are usually equipped with heat dissipation holes, which are designed to dissipate heat through forced convection, thereby preventing the computer from overheating and maintaining stable performance. However, after a period of use, these heat dissipation holes are often blocked due to the entry of dust, which blocks the air circulation rate and reduces the air passing area, affecting the heat dissipation effect of the cooling fan, increasing energy consumption, causing the surface temperature of the computer to rise, and may even cause various problems. Dust may come from the working environment, such as offices, factories or other dusty environments, or users use laptops in harsh environments. Dust may also come from the computer itself, such as dust generated by the operation of components such as the CPU and GPU, all of which may make the heat dissipation holes more easily blocked. In addition, the design of some laptops may make their heat dissipation holes more easily blocked by dust. For example, the fans and heat dissipation holes of some thin and light laptops are often designed together. If a large amount of dust is inhaled when the fan rotates, it may cause a decrease in the heat dissipation effect.

[0003] Therefore, the problem of dust blocking the cooling holes of existing laptop computers has become a difficult problem that needs to be solved urgently in the industry. Although there are some existing technologies for cleaning the cooling holes of laptop computers, these technologies often require additional tools or steps, which makes users feel inconvenient. For example, the utility model patent with application number 201820623084.8 discloses a laptop computer cooling device with dust removal function. The working principle of the cooling device is to add a filter and remove dust by replacing the filter. Summary of the invention
