Computer internal dust cleaning device

The invention discloses a computer interior dust cleaning device, and relates to the technical field of computer cleaning devices, and the computer interior dust cleaning device comprises a fan which generates suction force in the computer interior dust cleaning device; the first mounting shell is used for mounting a fan; the cleaning rotating mechanism is located on one side of the first mounting shell; the brush moving mechanism is located on one side of the cleaning rotating mechanism; the dust collection box is located below the first mounting shell; the dust removal device has the beneficial effects that the length of the brush can be adjusted, during cleaning, the brush automatically rotates by a certain angle, rotates in the opposite direction and reciprocates back and forth, elements in the case are more efficiently subjected to dust removal through back-and-forth rotation and vibration of the brush, and the dust removal efficiency is improved. And the phenomenon that the brush head of the brush is ea
