Referring to the third, sixth and tenth drawings, since the circumferential portion 1 2 B of the non-return device 12 is airtight with the inner wall of the exhaust pipe 2 (and the inner wall 3!) of the exhaust pipe, & When the anti-reverse position 1 2 is located at the airtight position, the gas 9 2 ' located at the 2nd end of the discharge end portion can be prevented from flowing backward into the other end by the discharge end portion 丄 2 toward the suction end portion u This design prevents dirty air (such as the final taste) on some floors of the building from passing through the central air conditioner and drifting up to the floor. ^ 〕,. Simple construction. The creation is only to provide a gas-tight circumferential portion on the non-return device that can be arranged with the inner wall of the evacuation panel (or the inner wall of the extension tube), that is, to prevent the end of the discharge end from being unactivated in the case where the forced draft device is not activated. The dirty air flows back to other spaces and the structure is quite simple. low cost. This creation is only when the anti-reverse device is formed, and the circumference is cut out on the contour. The object is not loaded with any parts, so the cost is extremely low. [Simple description of the diagram] 6 M400572 The first picture: an exploded view of the first example of the creation.
