[0025] During operation, when the indoor air is ventilated, the ventilation device will filter the outdoor air through the filter plate and then transport it into the room. The filter plate needs to be replaced after being used for a period of time. Since the existing ventilation device is not convenient for replacing the filter plate, it is inconvenient to use. In this solution, the spring 9 will always push the baffle 8 in the main air duct 1 of the box in the initial state, so that the pull rod 7 drives the latch 10 to be clamped in the slots 11 on both sides of the filter plate 301, so as to fix the filter plate 301 in the main air duct 1. When replacing the filter plate 301, first move the sliding plate 14 from directly below the installation slot 2.

Under the action of the spring 9, the latch 10 will clamp the filter plate 301 in the main air duct 1 again, and then the sliding plate 14 can be restored to its original position to complete the replacement. The purpose of replacing the filter plate is achieved by cooperation, and the rapid replacement of the filter plate in the ventilation device is realized, which is more convenient to use than traditional ventilation equipment.

[0026] See also Figure 1 As shown, a first rib 17 is installed on the outer side of the opening of the end of the main air duct 1 opposite to the air intake grille 16, a C-shaped fixing frame 18 is arranged on the outer side of the port of the main air duct 1, and a swing cover plate 19 is installed on the opening edge of the C-shaped fixing frame 18 through a pin shaft, and a first rib groove 20 and a second rib groove 21 are provided on the swing cover plate 19 and in the C-shaped fixing frame 18, a first vertical plate 22 is installed on the end of the swing cover plate 19, and a second vertical plate 22 is installed on the upper side of the opening of the C-shaped fixing frame 18. 3. The side surfaces of the No. 1 vertical plate 22 and the No. 2 vertical plate 23 are penetrated with threaded holes, and bolts 24 are penetrated in the threaded holes. A secondary air duct 25 is arranged at the port of the main air duct 1, and a No. 2 rib 26 is installed on the outer side of the port of the secondary air duct 25. The No. 1 rib 17 and the No. 2 rib 26 are both arranged in a U-shape, and the No. 1 rib groove 20 and the No. 2 rib groove 21 are parallel to each other. The No. 1 rib 17 and the No. 2 rib 26 can be respectively and correspondingly clamped in the No. 1 rib groove 20 and the No. 2 rib groove 21.

[0027] During operation, the existing ventilation device has a large overall structure and requires the cooperation of multiple workers for installation, which makes it inconvenient to install. In this solution, after the main air duct 1 is fixedly installed, the C-shaped fixing frame 18 is sleeved at the port of the main air duct 1. When sleeved, the No. 1 rib 17 is aligned with the No. 1 rib groove 20 and slidably inserted into it. Then, the No. 2 rib 26 at the port of the secondary air duct 25 is aligned with the No. 2 rib groove 21 in the C-shaped fixing frame 18 and slidably inserted into it, and the secondary air duct 25 is connected to the main air duct 1. Then, the swing cover 19 is rotated and closed in the C-shaped fixing frame. The opening of the frame 18 is then aligned with the bolts 24 and screwed into the threaded holes provided on the No. 1 vertical plate 22 and the No. 2 vertical plate 23. At this time, the connection and installation of the main air duct 1 and the secondary air duct 25 can be completed by the swing cover 19 and the limiting fixation of the C-shaped fixing frame 18.

The installation of the ventilation device is achieved, and the segmented and graded installation of the ventilation device is realized. Compared with the traditional ventilation device, the graded structure is smaller as a whole and more convenient to install.

[0028] Working principle: when the room is ventilated, the ventilation device will filter the outdoor air through the filter plate and then transport it into the room. The filter plate needs to be replaced after being used for a period of time. Since the existing ventilation device is not convenient for replacing the filter plate, it is inconvenient to use. In this solution, in the initial state, the spring 9 will always push the baffle 8 in the main air duct 1 of the box, and then the pull rod 7 drives the latch 10 to be stuck in the slots 11 on both sides of the filter plate 301, so as to fix the filter plate 301 in the main air duct 1. When replacing the filter plate 301, first move the sliding plate 14 from directly below the installation slot 2. When the sliding plate 14 moves, it will slide in the sliding slot 13 opened on the inner side of the two side plates 12. At this time, pull the two pull rods 7 outward. When the pull rod 7 is pulled, it will drive the baffle 8 to squeeze the spring 9 to the side of the second fixed plate 6, and pull the pull rod 7. When the filter plate 301 is completely pushed into the main air duct 1, the slot 11 is aligned with the latch 10. Under the action of the spring 9, the latch 10 will clamp the filter plate 301 in the main air duct 1 again, and the sliding plate 14 can be restored to its original position to complete the replacement. The purpose of replacing the filter plate is achieved by cooperation, and the rapid replacement of the filter plate in the ventilation device is realized, which is more convenient to use than the traditional ventilation equipment.

[0029] However, since the overall structure of the existing ventilation device is relatively large, it requires the cooperation of multiple workers to install it, which makes it inconvenient to install. In this solution, after the main air duct 1 is fixedly installed, the C-shaped fixing frame 18 is sleeved at the port of the main air duct 1, and the No. 1 rib 17 is aligned with the No. 1 rib groove 20 and slidably inserted into it during the sleeve installation, and then the No. 2 rib 26 at the port of the secondary air duct 25 is aligned with the No. 2 rib groove 21 in the C-shaped fixing frame 18 and slidably inserted into it, so that the secondary air duct 25 is connected to the main air duct 1, and then the swing cover 19 is rotated and sealed in the C-shaped fixing frame 1 8, and then align the bolts 24 with the threaded holes provided on the No. 1 vertical plate 22 and the No. 2 vertical plate 23 and screw them in. At this time, the main air duct 1 and the secondary air duct 25 can be connected and installed by the swing cover 19 and the C-shaped fixing frame 18. The ribs, C-shaped fixing frame 18 and rib grooves are set as required at the other end of the secondary air duct 25 to complete the installation of the multi-stage air duct. The installation of the ventilation device is achieved, and the segmented and graded installation of the ventilation device is realized. Compared with the traditional ventilation device, the graded structure is smaller as a whole and more convenient to install.
