Abstract

The invention discloses an efficient environment-friendly purification device which comprises a filter assembly, a fan and a treatment box, the fan comprises an impeller and a shell, the impeller comprises a front cover plate (1), a rear cover plate (2), a main blade (3) and splitter blades (4), and the efficient environment-friendly purification device is characterized in that the main blade comprises a first arc-shaped body part (31) and a first protruding part (32), and the first protruding part is arranged on the pressure face side of the main blade; the splitter blade comprises a second arc-shaped body part (41) and a second protruding part (42), the second protruding part is arranged on the negative pressure face side of the splitter blade, and the second protruding part is located on the radial outer side of the first protruding part. The pressure distribution in the impeller passage can be changed, the pressure loss can be reduced and the air pressure of the fan can be improved while the pressure distribution is homogenized, so that the output pressure of the fan is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection devices and purification devices, in particular to a high-efficiency environmental protection purification device and a fan. Background technique [0002] like figure 1 As shown, a high-efficiency environmental protection purification device includes a filter assembly, a fan, and a treatment box. The treatment box is provided with a filter assembly and a fan. The fan includes an impeller and a casing. The impeller is installed in the casing and rotates under the drive of a motor. The impeller includes a front cover 1, a rear cover 2, a main blade 3, and a splitter blade 4. A plurality of main blades 3 and a splitter blade 4 are connected between the front cover 1 and the rear cover 2 and are distributed along the circumferential direction. The main blades 3 and the splitter vanes 4 are alternately arranged in the circumferential direction. It homogenizes pressure distribution an...
