[0024] In the embodiment, the pressure assembly comprises a reset spring 13, a sliding rod 14, a sliding groove 15, a push rod 16, a sealing stress plate 17, an air inlet groove 18, a connecting groove 19, an air outlet groove 20 and a receiving plate, the indoor environment air outlet 3 is fixedly connected with the receiving plate, one end of the receiving plate is provided with the air inlet groove 18, the receiving plate is provided with the connecting groove 19, the other end of the receiving plate is provided with a group of air outlet grooves 20, the air outlet grooves 20 are communicated with the air inlet groove 18 through the connecting groove 19, the receiving plate is provided with the sliding groove 15, the sliding groove 15 is communicated with the connecting groove 19, the center of the sliding groove 15 and the center of the air inlet groove 18 are located on the same horizontal line, the push rod 16 is slidably connected in the indoor environment air outlet 3, one end of the push rod 16 is fixedly connected with the sealing stress plate 17, the sealing stress plate 17 is arranged in the air inlet groove 18, the push rod 16 penetrates through the connecting groove 19, and one end of the push rod 16 is arranged in the sliding groove 15, one end of the push rod 16 away from the sealing stress plate 17 is fixedly connected with the sliding rod 14, the sliding rod 14 is sleeved with the reset spring 13, the reset spring 13 is arranged in the sliding groove 15, and one end of the sliding rod 14 penetrates through the sliding groove 15, the reset spring 13 can effectively store elastic potential energy, so that indoor air can be accumulated in the grille type radiator 6 when the pressure is small, thereby increasing the contact time with external air and ensuring the heat exchange process, and when the pressure is a certain degree, the reset spring 13 can be extruded and the sealing stress plate 17 can be pushed into the connecting groove 19, so that the air outlet channel can be opened, the air in the grille type radiator 6 can be discharged, and after the pressure is restored, the sealing stress plate 17 can be resealed to the air inlet groove 18 under the action of the reset spring 13, so that the air outlet channel is closed.

[0025] The first fan group 4 (located at the external environment air inlet 2) and the second fan group 11 (located at the external environment air outlet 9) start to work to form a preliminary air flow. The first fan group 4 introduces external air into the mixing bin 5 in the shell 1 through the external environment air inlet 2. After entering the mixing bin 5, the external air passes through the filter screen 10 in the external environment air outlet 9 to remove dust and other impurities, ensuring that the air entering the room is clean. The external air and the internal air meet in the mixing bin 5. Due to the action of the first fan group 4 and the second fan group 11, the air flow in the mixing bin 5 remains flowing. The grating type radiator 6 connects the indoor environment air inlet 8 and the indoor environment air outlet 3. The internal air enters the grating type radiator 6 through the radiator input end 7 and is discharged to the outside through the radiator output end. The grating type radiator 6 increases the contact area of the indoor air and the external air. When there is a temperature difference between the two, heat is exchanged through the grating type radiator 6. The heat of the internal air is transferred to the external air. As the external air continues to be discharged, the pressure in the indoor environment air outlet 3 gradually increases. When the pressure reaches a certain value, the sealing force plate 17 is pushed open. The sliding rod 14 moves in the sliding groove 15. The return spring 13 is compressed. The sealing force plate 17 moves to the inside of the connecting groove 19. The air outlet groove 20 and the air inlet groove 18 are connected through the connecting groove 19. The air in the grating type radiator 6 is discharged through the air outlet groove 20. As the air is discharged, the pressure in the indoor environment air outlet 3 gradually decreases. The return spring 13 returns to its original state, pushing the sliding rod 14 and the sealing force plate 17 back to the initial position, sealing the air inlet groove 18 and closing the air outlet channel. The above process continues during the operation of the fresh air machine, ensuring effective exchange of indoor air and external air and efficient recovery of heat.

[0026] The flow guide assembly can effectively increase the contact area of the indoor air and the external air. While ensuring the effective discharge of the indoor air, its heat can be further volatilized into the mixing bin 5. Thus, when the external air is introduced into the mixing bin 5, its heat can be taken away, so that the heat can be reused in the room. With the assistance of the pressure assembly, the indoor air can stay in the grating type radiator 6 for a long time, so that the heat in the grating type radiator 6 can be effectively introduced into the mixing bin 5 and taken away by the external air. The heat in the indoor air can be further intercepted, and the same applies to the cold air.

The description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
