In order to explain the technical solution of the present invention, the following detailed description is made with reference to fig. 1 to 3 and the embodiments.

Please refer to fig. 1, which is an embodiment of the present invention, an air purifier includes: outer shell 100, filter element 200 and wind guide element 300, be formed with the wind channel 400 that supplies the circulation of air in outer shell 100, wind channel 400 has wind channel import 410 and the wind channel export 420 of setting on outer shell 100, filter element 200 installs in wind channel 400, and be located the position that is close to wind channel import 410, wind guide element 300 installs in wind channel 400, and be located the position that is close to wind channel export 420, be equipped with pressure intensifying structure 430 in wind channel 400, pressure intensifying structure 430 is located between filter element 200 and the wind guide element 300, pressure intensifying structure 430 has pressure boost intake 431 and pressure boost air outlet 432, pressure boost intake 431 is close to filter element 200, pressure boost air outlet 432 is close to wind guide element 300, the internal diameter of pressure boost intake 431 is greater than the internal diameter of pressure boost air. Specifically, the air cleaner in this embodiment is a cylindrical air cleaner.

Because the design that pressure boost air intake 431 internal diameter is greater than pressure boost air outlet 432 internal diameter among the pressure boost structure, make the velocity of flow increase of pressure boost air outlet 432 department air, the circulation speed of air has been improved, the efficiency of admitting air of wind wheel 320 has been promoted, it is great to have solved the inside windage of air purifier under the prerequisite that does not improve power device's power, the not smooth problem of circulation of air, produce extra noise and energy consumption when avoiding air purifier to use, the effective static pressure value in whole wind channel has been increased, air purifier's work efficiency has been improved.
