[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, by providing a quick-install component, when the staff installs the fresh air ventilator, they only need to align the first fixing plate and the second fixing plate with the grooves of the mounting seat respectively and slide them. When the second fixing plate is displaced, the toothed bar is driven to displace synchronously, and at the same time, the toothed bar is meshed and connected with the gear. When the toothed bar is displaced, the gear is driven to rotate, and the gear drives the first gear to rotate synchronously. The first gear and the second gear are meshed and connected. When the first gear rotates, the second gear is driven to rotate synchronously. The second gear drives the transmission rod to rotate, and the transmission rod drives the first threaded rod to rotate. When the transmission rod rotates, the power rod is driven to rotate synchronously through the belt and the pulley. When the power rod rotates, the second threaded rod is driven to rotate, so that the second threaded rod rotates synchronously with the first threaded rod. The second threaded rod is threadedly connected to the outer wall of the first threaded rod and the inner threaded ring. When the second threaded rod and the first threaded rod rotate, the inner threaded ring is driven to move on its outer wall. When the inner threaded ring moves, the clamping plate is driven to move through the connecting rod. The clamping plate is displaced on the outer wall of the mounting seat so that it clamps one side of the first fixing plate and the second fixing plate. The pin provided on the side wall of the clamping plate is inserted into the pin hole provided on one side of the first fixing plate and the second fixing plate, so that the mounting seat tightly clamps the outer shell. Through this design, the fresh air exchanger can be effectively installed quickly without the need for staff to perform multiple steps, avoiding the need for staff to spend a long time to operate before disassembling it, saving time and effort, greatly increasing the maintenance efficiency of the staff, and greatly reducing the labor intensity of manual labor, with good use effect.

[0016] 2. In the present invention, a buckle assembly is provided, so when the fresh air exchanger needs to be disassembled from the mounting seat, the turntable needs to be rotated first, and the turntable drives the limit rod to rotate through the connecting piece, and the limit rod simultaneously drives the long rod to rotate, so that the limit rod coincides with the clamping hole set on one side of the mounting seat. At this time, the second spring provided on the outer wall of the lower pressing block is in a stretched state, and the elastic force generated by the second spring in the stretched state drives the lower pressing block to move, and the displacement of the lower pressing block drives the long rod to move at the same time, and the long rod drives the limit rod to move, so that the limit rod passes through the clamping hole set on one side of the mounting seat, so that one end of the limit rod is on the same horizontal line with the clamping hole, and the turntable can be rotated again to make the turntable The cam is in a reset state and is in its original state. The turntable drives the limit rod to move synchronously. One end of the limit rod is in a non-overlapping state with the card hole. Before the lower pressure block moves up, the first spring arranged on the top of the plug block is in a stretched state. After the lower pressure block moves up, the elastic force generated by the first spring in the stretched state drives the plug block to move. The plug block is removed from the socket arranged at the bottom of the gear, and the restricted rotation of the gear is released. The quick-release assembly can be disassembled according to the working principle of the quick-release assembly described above. This design effectively realizes the restricted rotation of the gear in the quick-release assembly, avoids its free rotation under external factors, greatly improves the stability of the equipment, and has a good use effect.

[0017] 3. In the present invention, a filter changing assembly is provided, and when the filter screen arranged inside the shell needs to be replaced, the filter screen frame is squeezed before the door, and the filter screen frame also squeezes the reset plate, and the reset plate squeezes one end of the reset spring to put it in a compressed state, and it only needs to open the door. When the door is opened, the filter screen frame is no longer squeezed, and the filter screen frame also no longer squeezes the reset plate. When the reset spring is in a compressed state, elastic force is generated to drive the reset plate to move, and the reset plate pushes one side of the filter screen frame to move, so that the other side of the filter screen frame is pushed out of the shell. The staff only needs to grab the other side of the filter screen frame to take out the filter screen frame, and the filter screen frame drives the filter screen to be moved out at the same time to replace the filter screen. Through this design, the blocked filter screen is effectively replaced, and the new filter screen is replaced to the inside of the shell, so that the filter screen inside the shell is avoided to be blocked, the ventilation effect of the filter screen is greatly improved, and the use effect is good.

It is only necessary to open the door 51. The filter screen frame 52 is no longer squeezed by the door 51. The filter screen frame 52 also no longer squeezes the reset plate 57. When the reset spring 59 is in a compressed state, an elastic force is generated to drive the reset plate 57 to move. The reset plate 57 pushes one side of the filter screen frame 52 to move, so that the other side of the filter screen frame 52 pops out of the shell 2.

[0031] Working principle: When installing the fresh air ventilator, the staff only needs to align the first fixing plate 31 and the second fixing plate 32 with the grooves of the mounting seat 1 respectively and slide them. When the second fixing plate 32 moves, the toothed bar 33 is driven to move synchronously. At the same time, the toothed bar 33 is meshed with the gear 34. When the toothed bar 33 moves, the gear 34 is driven to rotate. The gear 34 drives the first gear 36 to rotate synchronously. The first gear 36 is meshed with the second gear 37. When the first gear 36 rotates, it drives the second gear 37 to rotate synchronously. The second gear 37 drives the transmission rod 38 to rotate, and the transmission rod 38 drives the first threaded rod 39 to rotate. When the transmission rod 38 rotates, it is connected to the pulley 3 through the belt 312. 13 drives the power rod 310 to rotate synchronously. When the power rod 310 rotates, the second threaded rod 311 is driven to rotate, so that the second threaded rod 311 and the first threaded rod 39 rotate synchronously. The outer wall of the second threaded rod 311 and the first threaded rod 39 is threadedly connected with the inner threaded ring 314. When the second threaded rod 311 and the first threaded rod 39 rotate, the inner threaded ring 314 is driven to move on its outer wall. When the inner threaded ring 314 moves, the clamping plate 35 is driven to move through the connecting rod. The clamping plate 35 is displaced on the outer wall of the mounting seat 1 so that it clamps one side of the first fixing plate 31 and the second fixing plate 32. The pins provided on the side walls of the clamping plate 35 are inserted into the pins provided on the first fixing plate 31 and the second fixing plate 32. The mounting base 1 is inside the pin hole and tightly clamps the outer shell 2. When the fresh air exchanger needs to be removed from the mounting base 1, the turntable 411 needs to be rotated first. The turntable 411 drives the limit rod 410 to rotate through the connecting piece 412. The limit rod 410 simultaneously drives the long rod 49 to rotate, so that the limit rod 410 coincides with the clamping hole set on one side of the mounting base 1. At this time, the second spring 47 set on the outer wall of the lower pressure block 46 is in a stretched state. The elastic force generated by the second spring 47 in the stretched state drives the lower pressure block 46 to move. The displacement of the lower pressure block 46 drives the long rod 49 to move at the same time. The long rod 49 drives the limit rod 410 to move, so that the limit rod 410 passes through the clamping hole set on one side of the mounting base 1, so that one end of the limit rod 410 is on the same horizontal line as the clamping hole. , the turntable 411 can be rotated again to reset the turntable 411 to the original state, and the turntable 411 drives the limit rod 410 to move synchronously, and one end of the limit rod 410 is in a non-overlapping state with the card hole. Before the lower pressing block 46 moves up, the first spring 45 set on the top of the plug block 41 is in a stretched state. After the lower pressing block 46 moves up, the elastic force generated by the first spring 45 in the stretched state drives the plug block 41 to move, and the plug block 41 is moved out of the socket set at the bottom of the gear 34, and the gear 34 is released from the rotation restriction. It can be disassembled according to the working principle of the quick-install assembly described above. When the filter set inside the shell 2 needs to be replaced, because the door 51 squeezes the filter frame 52 before, the filter frame 52 also squeezes the reset plate 57.The reset plate 57 squeezes one end of the reset spring 59 to put it in a compressed state. The door 51 only needs to be opened. The filter frame 52 is no longer squeezed by the door 51. The filter frame 52 also no longer squeezes the reset plate 57. When the reset spring 59 is in a compressed state, elastic force is generated to drive the reset plate 57 to move. The reset plate 57 pushes one side of the filter frame 52 to move, so that the other side of the filter frame 52 pops out of the housing 2. The staff only needs to grab the other side of the filter frame 52 to take out the filter frame 52. The filter frame 52 also drives the filter 53 to move out and replace the filter 53.
