[0009] Preferably, the protective grille consists of a plurality of horizontal bars and a plurality of vertical bars.

[0010] Preferably, the front volute and the rear volute are fixedly connected by a plurality of bolts.

[0011] Preferably, the front volute, the first air outlet housing and the protective grille are integrally formed by injection molding;

[0012] The rear volute, the second air outlet housing and the protective grille are integrally formed by injection molding.

[0013] Preferably, the air inlet is provided on the front volute;

[0014] The rear volute is provided with a motor compartment extending backward, and the motor is fixedly installed in the motor compartment.

[0015] Preferably, the air inlet is a honeycomb mesh structure.

[0016] Compared with the prior art, the present invention comprises a first air outlet housing and a second air outlet housing that are combined to form an air outlet duct, which is interconnected with the interior of the housing; a protective grille is provided at the end of each of the first and second air outlet housings away from the housing, and the front and rear protective grilles are combined to form a protective net; the first air outlet housing and the protective grille are an integral structure; and the second air outlet housing and the protective grille are an integral structure. The present invention provides protective grilles on the first and second air outlet housings so that when the front and rear volutes are assembled, the front and rear protective grilles automatically combine to form a protective net, eliminating the existing process of separately manufacturing and assembling the protective net, effectively reducing production costs and improving production and assembly efficiency.
