Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an exploded view of the present invention;
FIG. 3 is a cross-sectional view of the blind;
in the figure: the device comprises an outer frame 1, a convex edge 1a, a positioning hole 1b, a sliding chute 1c, a vent 1d, a screen frame 2, a handle 2a, a screen 2b, a shutter 3, blades 4, a lower baffle 4a, an inclined plate 4b, an upper baffle 4c and a cross rod 5.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The air inlet mechanism of the environment regulating device comprises an outer frame 1, a filter screen frame 2 and a shutter 3; the outer frame 1 is provided with a through vent 1 d; the filter screen frame 2 is detachably inserted in the outer frame 1; the filter screen frame 2 is provided with a filter screen 2 b; the filter screen 2b covers the air vent 1 d; the louver 3 is fixedly mounted to the outer frame 1, and the louver 3 covers the vent 1 d.
A convex edge 1a is arranged at the edge of the inner side of the outer frame 1; the convex edge 1a is provided with a positioning hole 1 b. The arrangement of the convex edge 1a and the positioning hole 1b is beneficial to installing the air inlet mechanism on the outer wall of a wall surface or a ring main unit.
A horizontal sliding groove 1c is formed in the inner wall of the outer frame 1; the screen frame 2 is slidably mounted on the chute 1 c. A handle 2a is arranged on one side of the filter screen frame 2.
And the filter screen frame 2 is used for filtering air entering the ring main unit, so that the influence of dust on the electrical equipment is reduced. The arrangement of the sliding chute 1c and the handle 2a facilitates the replacement or cleaning of the filter screen frame 2.
