The utility model discloses an air purifier belongs to air purification equipment technical field. It includes: air inlet pipe and air outlet pipe, both upside down and connect, and both the top surface, bottom surface of air purifier structure formed after connecting are closed surface, the top surface of air outlet pipe is provided with the communicating port, and the inner chamber of air inlet pipe is communicated with the air outlet pipe through the communicating port, the circumferential side wall of air inlet pipe is provided with a plurality of air inlet face, and every air inlet face is provided with air inlet, the air outlet face is formed on the opposite setting two sides of air outlet pipe respectively, and every air outlet face is provided with air outlet, the filter screen is set in air inlet pipe and covers in communicating port. Set up air inlet and air outlet on every side wall of air inlet pipe and air outlet pipe respectively, can handle the air in larger range fast, realizes the uniform suction and high -efficient discharge of air, effectively promotes the air circulation times in unit time, thereby significantly enhances purification efficiency.

This utility model discloses a fan wheel structure and an air purifier. The fan wheel body has air inlet surfaces at both ends and two layers of air outlet surfaces on its lateral circumferential surface. Each layer consists of blades evenly distributed circumferentially, with adjacent blades forming an air outlet channel. The upper and lower blades are tilted in the same direction and staggered, so that the upper blades overlap the lower air outlet channel axially, improving airflow continuity and volume. The air purifier includes two opposing filter compartments, with an air inlet screen on the outer surface, a filter screen inside, and an air outlet screen on the side. The fan wheel body is located in the inner cavity, with its two air inlet surfaces corresponding to the filter compartments, and its air outlet surfaces facing the air outlet screens. The double-layer air outlet structure combined with the staggered blade design significantly improves air delivery capacity and efficiency; the symmetrical air inlet and outlet layout enhances the rationality of airflow organization and improves purification efficiency; the overall structure is compact, operates stably and with low noise, and is suitable for various air purification scenarios.
