1. A balanced pollutant cleaning system, comprising:
a fan;
an air jet device, wherein the air jet device is disposed around a shielded object and the air jet device is provided with a plurality of air jet ports, wherein an air inlet of the air jet device is connected to an air outlet of the fan through a pipeline, and when air is ejected from the plurality of air jet ports, an ejected airflow forms an air curtain around the shielded object;
an air suction device, wherein the air suction device is disposed above the shielded object, and the air suction device is configured to suction away pollutants and heat generated by the shielded object and the air ejected from the plurality of air jet ports; and
a control device, wherein the control device is configured to control a magnitude of an airflow output from the fan, and the control device is configured to adjust an air suction amount of the air suction device according to the magnitude of the airflow output from the fan,
wherein the air suction device is a range hood,
wherein the control device comprises a control module, a gas flowmeter, a voltage controller, and a speed adjustment button, wherein the control module is electrically connected to the gas flowmeter, the voltage controller, the speed adjustment button, and a drive circuit board of the range hood respectively, and the voltage controller is electrically connected to the fan.
