[0019] The utility model provides Figure 1-5 A double-layer curtain wall filter ventilator that is easy to clean is shown, comprising a ventilator body 1, one end of the ventilator body 1 is fixedly connected to an indoor air outlet 2, the other end of the ventilator body 1 is fixedly connected to a fixing ring 3, the front of the fixing ring 3 is symmetrically interlaced with a fixing block 6, the inner side of the fixing ring 3 is provided with a movable groove 301, the inside of the movable groove 301 is interlaced with a filter plate 5, the side of the filter plate 5 away from the fixing ring 3 is fixedly connected to a rain cover 4, and a fixing member for locking the filter plate 5 is provided at the intersection of the fixing block 6 and the fixing ring 3;

[0020] It should be noted that the model of the ventilator body 1 is APC10-5, the outer side of the ventilator body 1 is provided with a sound insulation cotton 7, and the outer side of the other end of the ventilator body 1 is provided with a sealing ring 8, the sound insulation cotton 7 is used to isolate the outdoor sound from being transmitted to the indoor, and the sealing ring 8 is provided at one end close to the outdoor to prevent rainwater from entering the indoor through the gap between the ventilator body 1 and the glass curtain wall. The material of the rain cover 4 is stainless steel, and an opening is provided at the bottom thereof for ventilation to prevent rainwater from entering the indoor, and the connection method between the fixing ring 3 and the ventilator body 1 is welding;

[0021] Specifically, the fixing member includes a slider 9, which is symmetrically fixedly connected to the side of the filter plate 5, one end of the slider 9 is inserted and connected to the inside of the movable groove 301, and one end of the slider 9 is inserted and connected to the side of the fixed block 6. A rotating groove 302 for the slider 9 to enter the movable groove 301 is opened on the front side of the fixing ring 3, and a locking groove 601 is opened at the insertion of the slider 9 and the fixed block 6. A locking part is provided at the bottom of the slider 9 and in the inner cavity of the locking groove 601;

[0022] It should be noted that the filter plate 5 is made of stainless steel, and its filter aperture is 1 mm. The slider 9 is connected to the filter plate 5 by welding. The movable groove 301 is connected to the locking groove 601. The movable groove 301 is an annular groove. The slider 9 enters the movable groove 301 through the rotating groove 302. The opening position of the rotating groove 302 is located at the bottom of the fixed ring 3, which can prevent rainwater from flowing into the movable groove 301.
