Electrical equipment covers the conversion, utilization and research of electric energy, including basic theory, application technology, facilities and equipment.

[0003] Nowadays, electrical equipment generally has a heat dissipation structure inside. Although it can effectively dissipate the heat of the electrical equipment during operation, a large amount of dust will accumulate on the internal circuit board of the electrical equipment after the electrical equipment has been used for a period of time, affecting the use of the electrical equipment. It is impossible to dissipate heat and clean the circuit board at the same time, and the actual application effect is not good. Therefore, there is an urgent need for a built-in circuit board cleaning device for electrical equipment to solve the above problems. Utility Model Content
