The invention relates to an intelligent air purifier wide in purification range. The intelligent air purifier wide in purification range comprises a base, a moving mechanism, universal wheels, a lifting mechanism and a purifying mechanism, wherein the moving mechanism and the universal wheels are arranged on the lower side of the base, the lifting mechanism and the purifying mechanism are arranged on the upper side of the base. The lifting mechanism is in transmission connection with the purifying mechanism. The purifying mechanism comprises a body, an air outlet pipe arranged on one side of the body, an angle adjusting mechanism arranged on the upper side of the body and an air inlet pipe. The angle adjusting mechanism is in transmission connection with the air inlet pipe. The air inlet pipe and the air outlet pipe both communicate with the body. The intelligent air purifier wide in purification range achieves movement through the moving mechanism, the height of the body is increased through the lifting mechanism, so that air at the high position can be conveniently purified, and therefore the air purification range of the intelligent air purifier is widened; in addition, the air inlet pipe is driven by the angle adjusting mechanism to change the angle, so that the body can conduct air suction and purification in multiple directions; and in this way, the air purification range of the intelligent air purifier wide in purification range is further widened, and the practicability of the intelligent air purifier wide in purification range is improved.
