The invention discloses an indoor air purification device capable of controlling the air intake volume, which comprises an air purifier, a left air inlet of the purifier, a right air inlet of the purifier, a right air inlet pipe, an air volume control valve, a front right air inlet pipe, Front right air inlet, front left air inlet, front left air inlet pipe, left air inlet pipe, left air inlet, right air inlet and purifier air outlet. The advantage of the present invention is that the air intake volume of the purifier can be controlled. When the indoor air environment is very turbid and the indoor air needs to be purified as soon as possible, the purpose of fast air intake can be achieved by increasing each air volume control valve; when a large air intake volume is not required , you can reduce or directly close one or several air volume control valves to achieve the purpose of reducing the air intake.
