The third oblique edge and the fourth oblique edge, the third and fourth oblique edges are respectively arranged on both sides of the rear mesh unit, and expand and extend from the axial center of the rear mesh cover toward the radial edge;

A plurality of third connecting portions and a plurality of fourth connecting portions are arranged opposite to each other on the third and fourth inclined edges with a predetermined distance.

Wherein: the plurality of radial front connecting parts and the plurality of radial rear connecting parts can be respectively a plurality of card holes and blocks; the plurality of first connecting parts and the plurality of second connecting parts are corresponding cards A hole and a block; the plurality of third connecting parts and the plurality of fourth connecting parts are corresponding locking holes and blocks.

The utility model has the following advantages:

1. Due to the unit modularization. The front screen unit or the rear screen unit can be combined into a front screen or a rear screen, especially the difference between the front and rear screens is that the axis of the rear screen must allow the motor shaft to pass through, so the front and rear screens In general, the same mold can be used for mass injection production (there is no safety regulation in the relevant industry that does not allow perforation at the axis of the front grille), so it can reduce mold costs, save mold change time, and reduce total production costs.

2. Assuming that the size of the front and rear screens is 12 inches, since the area of each front and rear screen unit is about one-sixth of the entire front and rear screens, in addition to reducing the size of the mold, the area can be as large as Therefore, it is very convenient for storage and transportation.
