Anion cleaning robot

A negative ion cleaning robot has a self-walking dust suction function and a negative ion releasing function and comprises a dust suction module and a main body. The dust suction module comprises a dust collecting box, a negative ion generator and a fan, the negative ion generator is used for generating negative ions, the fan is adjacent to the negative ion generator and used for generating air flow, external dust is guided to be collected in the dust collecting box by the air flow, and the air also can guide the negative ions to leave away from the negative ion cleaning robot. The main body is connected with the dust suction module and comprises a moving device and a control module, the moving device is used for driving the negative ion cleaning robot to move, and the control module is respectively electrically connected with the negative ion generator, the fan and the moving device so as to respectively control the negative ion generator, the fan and the moving device. The negative ion cleaning robot can release the negative ions to purify air while sucking the dust.
