As shown in fig. 3 and 5, the heat exchange plate 23 is provided to sufficiently exchange heat between the indoor air and the outdoor air in the heat exchanger 2, thereby increasing the heat exchange area; the purpose of the filter screen 51 is to filter the air entering the room from the outside, and to prevent contaminants from entering the room, contaminating the indoor air, and affecting the health of people.
As a further scheme of the invention, the filter screen 51 is fixedly arranged on a second rotating shaft 52, the second rotating shaft 52 is rotatably arranged on the heat exchanger 2, and the second rotating shaft 52 is externally connected with a power supply.
The filter screen 51 may be blocked with long-time operation during actual use, which affects ventilation efficiency. Therefore, as shown in fig. 4 and 9, the filter screen 51 is fixedly installed on the second rotating shaft 52, the second rotating shaft 52 drives the filter screen 51 to rotate, and the blocked filter screen 51 is partially moved out of the fresh air inlet 211, so that the unblocked filter screen 51 is partially moved to the fresh air inlet 211 to continue filtering, and the ventilation efficiency of the heat exchanger 2 is not affected; meanwhile, when the part of the filter screen 51 which is blocked moves to the dirty air outlet 212, dirty air can blow to the blocked part of the filter screen 51, clean the blocked part of the filter screen 51, blow the blocking object outdoors, clean the filter screen 51, facilitate the next use and circulate and reciprocate. The invention can automatically clean the filter screen 51, avoid manual cleaning, prolong the service life of the filter screen 51 and ensure the ventilation efficiency of the heat exchanger 2. The filter screen 51 is blocked at the fresh air inlet 211 because of the filtering sundries, and the invention utilizes the wind blown out by the sewage outlet 212 to reversely blow to the blocked position of the filter screen 51 to automatically clean the blocked position of the filter screen 51, thereby avoiding manual cleaning, prolonging the service life of the filter screen 51 and ensuring the ventilation efficiency of the heat exchanger 2.
As a further scheme of the invention, the fresh air inlet 211 and the dirty air outlet 212 are respectively rotatably provided with a first fan 53 and a second fan 54, the installation directions of the first fan 53 and the second fan 54 are opposite, and the first fan 53 is used for blowing air to the inner side of the wall body 1; the first fan 53 and the second fan 54 are respectively rotatably mounted on two third rotating shafts 55, the third rotating shafts 55 are rotatably mounted on the heat exchanger 2, a fourth gear 56 is fixedly mounted on the third rotating shafts 55, a fifth gear 57 is fixedly mounted on the second rotating shafts 52, and the fourth gear 56 is in transmission connection with the fifth gear 57.
In order to enhance ventilation effect of indoor and outdoor air, an exhaust fan is usually added at the outer air port. As shown in fig. 3 and 4, in the present invention, a first fan 53 and a second fan 54 are rotatably installed in a fresh air inlet 211 and a dirty air outlet 212, respectively, the first fan 53 is used for blowing outdoor air to the inner side of a wall body 1, and the second fan 54 is used for blowing indoor air to the outer side of the wall body 1, so as to enhance ventilation effect. The invention connects the rotation speed of the first fan 53 and the second fan 54 with the rotation speed of the second rotation shaft 52 through the fourth gear 56 and the fifth gear 57 in a transmission way, and changes synchronously.
As a further aspect of the present invention, a brake lever 61 is fixedly mounted on the closing plate 34, and a friction portion 62 is disposed at an end of the brake lever 61, and the friction portion 62 is used for friction with the second rotating shaft 52 to reduce the rotation speed of the second rotating shaft 52.
When the indoor-outdoor temperature difference gradually increases, the flow control unit reduces the ventilation efficiency by gradually reducing the caliber of the inner ventilation opening 22, and at this time, the first fan 53 and the second fan 54 should synchronously reduce the rotation speed to cooperate with the flow control unit to reduce the ventilation efficiency. As shown in fig. 7 and 9, when the closing plates 34 are driven by the gear plate 32 to approach each other and gradually reduce the caliber of the inner ventilation opening 22, the brake lever 61 on the closing plate 34 drives the friction portion 62 to rub against the second rotation shaft 52, the friction force gradually increases, the second rotation shaft 52 is driven by the external power source, and the rotation speed of the second rotation shaft 52 gradually decreases as the friction force gradually increases. Then the second rotation shaft 52 is in transmission connection with the fifth gear 57 through the fourth gear 56 to reduce the rotation speed of the first fan 53 and the second fan 54, and the ventilation efficiency is reduced by matching with the flow control unit, so that the heat exchange time of the indoor air and the outdoor air in the heat exchanger 2 is prolonged, the indoor air can be fully precooled and preheated to the fresh air, the influence of the fresh air on the indoor temperature is reduced, and meanwhile, the energy consumption is saved. Conversely, when the indoor and outdoor temperature difference gradually decreases, the friction force between the friction part 62 of the brake lever 61 on the closing plate 34 and the second rotating shaft 52 gradually decreases, the second rotating shaft 52 gradually returns to the recovery speed under the drive of the external power supply, and gradually increases, so that the rotating speeds of the first fan 53 and the second fan 54 gradually increase, and the ventilation efficiency is improved by matching with the flow control unit, so that the house can be ventilated rapidly, indoor air freshness is ensured, and the health of people is benefited. The invention not only gradually reduces and increases the caliber of the inner ventilation opening 22 through the closing plate 34 to adjust the ventilation efficiency of the heat exchanger 2; the friction force to the second rotating shaft 52 is gradually increased and reduced by utilizing the movement of the closing plate 34, so that the rotating speed of the second rotating shaft 52 is controlled, the rotating speeds of the first fan 53 and the second fan 54 are regulated, and the ventilation efficiency of the heat exchanger 2 is regulated by matching with the flow control unit, so that the regulation effect is better.
As a further scheme of the invention, a brush 7 is fixedly arranged on the heat exchanger 2, and the brush 7 is used for cleaning the filter screen 51. The purpose of this arrangement is to enhance the cleaning effect of the screen 51, as shown in figure 3. When the filter screen 51 rotates along with the rotation of the second rotating shaft 52, friction can occur between the filter screen 51 and the brush 7 fixedly arranged on the heat exchanger 2, the brush 7 cleans the filter screen 51 passing through, manual cleaning is avoided, the service life of the filter screen 51 is prolonged, and the ventilation efficiency of the heat exchanger 2 is ensured.
