[0018] 1. In the utility model, a quick-release assembly is provided. When the filter needs to be removed, only the pull plate needs to be pulled. The pull plate drives the first extrusion plate to move through the first connecting rod. At the same time, the first extrusion plate drives the fixed plate to move through the second connecting rod. The fixed plate drives the latch to move so that it is moved out of the latch hole provided on the side wall of the filter. The first spring is squeezed by the first extrusion plate to form a compressed state. At this time, the filter can be easily taken out. Through this design, the filter on the fresh air ventilation device can be quickly disassembled, making the filter easier to clean and clear blocked holes, greatly improving the cleaning efficiency, and having a good use effect.

[0019] 2. In the utility model, a fixing component is provided, when the pull plate is displaced to the end of the first shell, the pull plate squeezes the tip of the front part of the buckle block, and when the buckle block is squeezed, it moves upward, and the buckle block drives the long plate to move, and while the long plate is displaced, it drives the long rods arranged at the bottom of both ends to move, and the long rods drive the second extrusion plate at the bottom to move, and the second extrusion plate squeezes the second spring at the same time, so that the second spring stroke is in a compressed state, and when the pull plate passes over the tip of the front part of the buckle block and reaches the middle end of the buckle block, the buckle block is no longer squeezed, and the elastic force of the second spring resets it, and the pull plate is fixed to the end of the first shell. Through this design, the pull plate in the quick-release assembly is effectively fixed, so that the pull plate does not need to be fixed manually for a long time, which greatly reduces the labor intensity when disassembling the filter.

[0028] The quick release assembly 3 includes a first housing 31, an outer wall of which is provided with a travel groove 32, a bottom cover plate 38 is fixedly mounted on the bottom of the first housing 31, a first spring 37 is fixedly mounted on the outer wall of the bottom cover plate 38, and a first extrusion plate 36 is fixedly mounted on the other end of the first spring 37;

[0029] A first connecting rod is fixedly installed on one side of the first extrusion plate 36, a pull plate 34 is fixedly installed on the other end of the first connecting rod, the travel groove 32 is slidably connected to the first connecting rod, a second connecting rod is fixedly installed on the other side of the first extrusion plate 36, a fixing plate 35 is fixedly installed on the other end of the second connecting rod, a latch 33 is fixedly installed on the outer wall of the fixing plate 35, and the inner wall of the slide groove provided on the outer wall of the housing 1 is slidably connected to the second connecting rod;

[0030] The specific implementation method is as follows: when the filter screen 2 needs to be removed, only the pull plate 34 needs to be pulled, and the pull plate 34 drives the first extrusion plate 36 to move through the first connecting rod. At the same time, the first extrusion plate 36 drives the fixed plate 35 to move through the second connecting rod, and the fixed plate 35 drives the latch 33 to move so that it is moved out of the latch hole set on the side wall of the filter screen 2. The first spring 37 is squeezed by the first extrusion plate 36 to form a compressed state. At this time, the filter screen 2 can be easily taken out.

[0031] The fixing assembly 4 includes a second shell 41 and a long rod 43. The second shell 41 is fixedly mounted on both sides of the first shell 31. A second extrusion plate 42 is fixedly mounted on one end of the long rod 43. The long rod 43 passes through a through hole set at the top of the second shell 41. A second spring 44 is sleeved on the outer wall of the long rod 43. One end of the second spring 44 is fixedly mounted on the top of the second shell 41. The other end of the second spring 44 is fixedly mounted on the outer wall of the second extrusion plate 42. A long plate 45 is fixedly mounted on the other end of the long rod 43. Buckle blocks 46 are fixedly mounted on the outer walls of both ends of the long plate 45.

[0032] The specific implementation method is as follows: when the pull plate 34 moves to the end of the first shell 31, the pull plate 34 squeezes the tip of the front part of the buckle block 46. When the buckle block 46 is squeezed, it moves upward, and the buckle block 46 drives the long plate 45 to move. While the long plate 45 moves, it drives the long rod 43 set at the bottom of both ends to move. The long rod 43 drives the second squeezing plate 42 at the bottom to move. The second squeezing plate 42 squeezes the second spring 44 at the same time, so that the second spring 44 is in a stroke compression state. When the pull plate 34 passes over the tip of the front part of the buckle block 46 and reaches the middle end of the buckle block 46, the buckle block 46 is no longer squeezed, and is reset due to the elastic force of the second spring 44, so that the pull plate 34 is fixed to the end of the first shell 31.

[0033] Working principle: When the filter 2 needs to be removed, only the pull plate 34 needs to be pulled. The pull plate 34 drives the first extrusion plate 36 to move through the first connecting rod. At the same time, the first extrusion plate 36 drives the fixing plate 35 to move through the second connecting rod. The fixing plate 35 drives the latch 33 to move so that it moves out of the latch hole set on the side wall of the filter 2. The first spring 37 is squeezed by the first extrusion plate 36 to form a compressed state. At this time, the filter 2 can be easily taken out. When the pull plate 34 moves to the end of the first shell 31, the pull plate 34 squeezes the tip of the front part of the buckle block 46, and the buckle block When 46 is squeezed, it moves upward, and the buckle block 46 drives the long plate 45 to move. While the long plate 45 moves, it drives the long rods 43 set at the bottom of both ends to move. The long rods 43 drive the second squeezing plate 42 at the bottom to move. The second squeezing plate 42 squeezes the second spring 44 at the same time, so that the second spring 44 is in a compressed state. When the pull plate 34 passes the tip of the front part of the buckle block 46 and reaches the middle end of the buckle block 46, the buckle block 46 is no longer squeezed and is reset due to the elastic force of the second spring 44, so that the pull plate 34 is fixed at the end of the first shell 31.
