The invention discloses a simple type household air purification device. The simple type household air purification device comprises a machine body, an HEPA filter screen and a negative ion generator;a solar cell panel is arranged at the upper end of the machine body, and a carrying handle is arranged at the upper end of the solar cell panel; the HEPA filter screen is arranged in the machine body, and an activated carbon adsorbing net is arranged on one side of the HEPA filter screen; the negative ion generator is arranged on one side of the activated carbon adsorbing net; a photocatalyst netis arranged on one side of the negative ion generator; a base is arranged at the lower end of the machine body; universal self-locking wheels are arranged at the bottom of the base; a dust collectingbox is arranged in the base, and the bottom of the dust collecting box is connected with a dust sucking port; a loudspeaker is arranged on one side of the machine body; due to the arrangement of thenegative ion generator, negative ion flow generated by the negative ion generator adsorbs suspended particulate matter with positive charges in air, so that the particulate matter is ceaselessly accumulated and becomes heavy, and then breaks away from a gas dissolved state for settlement; and due to the arrangement of the dust sucking port, dust on the ground can be sucked into the dust collectingbox.
