DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-7, a ventilation structure of an air conditioning fresh air system, comprising a body 1, an outdoor air inlet 2 and an indoor air outlet 3 are arranged on one side of the body 1, an indoor air inlet 4 and an indoor air supply 5 are arranged on the other side of the body 1, a first Y-shaped support leg 6 is connected to the top and bottom ends of the body 1, a second Y-shaped support leg 7 is connected to both sides of the body 1, a full heat exchange core 8 is movably installed between the two first Y-shaped support legs 6 and the two second Y-shaped support legs 7, side panels 9 are connected to the first Y-shaped support legs 6 and the second Y-shaped support legs 7 at the outdoor air inlet 2 and the indoor air inlet 4, a filter 10 is movably connected between the two side panels 9 in the same area, a fan 11 is arranged at the indoor air outlet 3 and the indoor air supply 5 inside the body 1, and a sealing plate 12 is movably connected to one side of the body 1;

[0025] The same connection block 13 is connected between the two side plates 9 in the same area, and a notch 14 is provided on the connection block 13. The filter 10 is adapted in the notch 14. A plug hole 15 is provided on the inner wall at one end of the notch 14. First springs 16 are connected to both sides of the plug hole 15. Wedge blocks 17 are connected to the two first springs 16. The filter 10 includes a frame 18, a filter membrane 19 and an inner core 20. The filter membrane 19 is located between the frame 18 and the inner core 20. The inner core 20 is embedded in the frame 18. One side of the frame 18 A first plug post 21 is connected to the end, a second plug post 22 is connected to one end of the first plug post 21, the outer diameter of the second plug post 22 is smaller than the outer diameter of the first plug post 21, a first conical block 23 is connected to one end of the second plug post 22, a second conical block 24 is slidably mounted on the second plug post 22, the second conical block 24 is in the opposite direction to the first conical block 23, the wedge block 17 is located between the first conical block 23 and the second conical block 24, a slot 25 is opened on the sealing plate 12, and the specifications of the slot 25 are adapted to the filter 10.

[0026] The working process of the ventilation structure is that negative pressure is generated at the fan 11 at the indoor air supply port 5, and under the staggered structure inside the full heat exchange core 8, the indoor air supply port 5 area is connected with the outdoor air inlet 2 area, so that the outdoor air inlet 2 sucks in the outside fresh air and sends it into the body 1, and the dust and other impurities entrained in the outside fresh air are filtered through the filter 10 there, and then discharged from the indoor air supply port 5 to the room through the full heat exchange core 8. At the same time, the fan 11 at the indoor exhaust port 3 generates negative pressure, and in the full heat exchange core 8, the indoor exhaust port 3 is connected to the indoor air inlet 4, so that the indoor air inlet 4 sends the indoor air with dust and other impurities into the body 1, and the dust and impurities carried by the indoor air are filtered out by the filter 10 there, and discharged to the outside from the indoor exhaust port 3 through the full heat exchange core 8. When the outdoor fresh air and the indoor cold air enter the full heat exchange core 8 at the same time, heat exchange occurs. At this time, the outside air temperature decreases and enters the room, and the indoor air temperature rises and is discharged to the outside, and the cycle repeats;

[0027] After using for a period of time, the filter 10 needs to be taken out and the filter membrane 19 needs to be replaced. At this time, the filter 10 is pressed into the body 1, so that the frame 18 drives the first plug post 21, the second plug post 22 and the first conical block 23 to move deeper into the insertion hole 15. Due to the sliding of the second conical block 24, the wedge block 17 in the pop-up state relatively pushes the second conical block 24 to slide on the second plug post 22 and gradually contacts the first plug post 21. After contact, the second conical block 24 is restricted by the first plug post 21, so that the continuous pressing of the filter 10 acts on the second conical block 24, so that the wedge block 17 pushes the first spring 16 to contract, and the second conical block 24 moves from the wedge block 17. One side passes through to the deep part of the insertion hole 15, and the first spring 16 rebounds to push out the wedge block 17. When the filter 10 is taken out, the second conical block 24 first produces a sliding effect under the restriction of the wedge block 17 and fits with the first conical block 23. After fitting, the sliding of the second conical block 24 stops. Under the guidance of the conical inclined surface, the wedge block 17 pushes the first spring 16 to contract until the second conical block 24 and the first conical block 23 completely pass through the wedge block 17, thereby realizing the removal of the filter 10, taking out the inner core 20, replacing the filter membrane 19, and merging it with the frame 18, and then passing the filter 10 through the slot 25 and installing it in the body 1. During the process, there is no need to remove the sealing plate 12.

[0028] Specifically, in this embodiment, the inner diameter of the insertion hole 15, the outer diameter of the first plug post 21, the outer diameter of the first tapered block 23 and the outer diameter of the second tapered block 24 are all the same, thereby avoiding shaking of the filter 10 after installation.

[0029] Specifically, in this embodiment, a guide groove 26 is opened on the inner wall of the socket 15, the first spring 16 is connected to the inner wall of the guide groove 26 away from the opening, and the wedge block 17 is slidably fitted in the guide groove 26 to provide a stable movement guide for the wedge block 17.

[0030] Specifically, in this embodiment, a through hole 27 is formed on the second conical block 24 , and the inner diameter of the through hole 27 is the same as the outer diameter of the second plug post 22 , so as to prevent the second conical block 24 from shaking when moving.

[0031] Specifically, in the present embodiment, a second spring 28 is connected to the notch 14, a gasket 29 is connected to the second spring 28, the gasket 29 contacts the frame 18 of the filter 10, and the filter 10 contacts the gasket 29 after installation, forcing the second spring 28 to compress. With the cooperation between the wedge block 17 and the first conical block 23, the stability after installation is improved, and when the filter 10 is removed, the second spring 28 loses pressure and produces a rebound effect, thereby ejecting the filter 10 from the inside of the body 1, making the removal of the filter 10 more convenient.

[0032] Specifically, in this embodiment, a sliding hole 30 is opened in the slot 14 , a sliding rod 31 is slidably installed in the sliding hole 30 , and the sliding rod 31 is connected to one side of the pad 29 to prevent the second spring 28 from lateral deformation.

[0033] Specifically, in this embodiment, a sealing material of corresponding specifications, not limited to plastic rubber or foam plastic, can be inserted into the slot 25 to ensure the overall sealing performance inside the body 1 and the working stability of the ventilation structure. The slot 25 can be sealed according to the need to remove the filter 10.

[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
