Detailed Description
The following describes a specific embodiment of the present invention with reference to fig. 1 and 2.
The utility model discloses constitute by door opening 0, first door 1, two doors 2, blast pipe 3, air-blower 4, switch 5, cable 7 (fig. 1).
The section of the door opening 0 is of a rectangular structure and is made of transparent or semitransparent materials so as to be convenient for light transmission.
The first door 1 and the second door 2 are both rectangular structures with the length and the width not less than the cross section of the door opening, the first door 1 is installed on an inlet of the door opening through a hinge device 8, the second door 2 is installed on an outlet of the door opening through the hinge device 8, and the first door and the second door are both of outward opening door structures.
One end of the exhaust pipe 3 is closed, and the other end is installed on an air outlet of the blower 4. The side wall of the exhaust pipe is provided with a row of exhaust holes 6, and the opening direction of the exhaust holes is upward.
The exhaust holes 6 are used for ejecting air outwards, and a wind wall is formed at the outlet position of the door opening 0 to prevent winged insects from flying into the door opening 0.
The blower 4 is installed in the door opening at a position close to the outlet of the door opening 0. The blower 4 continuously injects air into the exhaust pipe 3.
The switch 5 is arranged at the outlet position of the door opening 0, and the switch 5 and the fan 4 are connected in series with the input power supply. The switch 5 is composed of a shell 16, a static contact block 9, a movable contact block 10, a spring 11 and a vertical rod 12 (figure 2).
