[0041] The present invention can be equipped with valves or fans at corresponding through holes as required to achieve different ventilation modes.

[0042] Embodiment 1:

[0043] In this embodiment, a fan 201 is provided on the upper fixing member 2 at the upper end of at least one side of the wall 1, and through holes are provided on both sides of the lower fixing member 3.

[0044] like Figures 1 to 4 As shown, in this embodiment, a first outer hole valve 203 is provided at the first outer through hole 202 on the outer side of the upper end fixing piece 2 of each side wall 1, but a first fan 201 is provided at the first inner through hole on the inner side of the upper end fixing piece 2 of at least one side wall 1, and a first inner hole valve is provided at the first inner through hole on the inner side of the upper end fixing piece 2 of the other side walls 1, and a second outer hole valve 309 is provided at the second outer through hole 308 on the outer side of the lower end fixing piece 3 of each side wall 1, and a second inner hole valve 303 is provided at the second inner through hole 302 on the inner side.

[0045] In this embodiment, the structures of the first outer hole valve 203 , the first inner hole valve, the second outer hole valve 309 and the second inner hole valve 303 are the same as those of the first diaphragm valve 205 and the second diaphragm valve 305 .

[0046] The working principle of this embodiment is:

[0047] When this embodiment is working, multiple ventilation modes can be adopted.

[0048] Mode 1: the second outer hole valve 309 on the outer side of the lower end fixing piece 3 of the side wall 1 provided with the first fan 201 is closed, the other valves are opened, and the valves on the other side walls 1 are also opened.

[0049] After the first fan 201 is started, outdoor fresh air flows in through the first outer hole 202 on the outside of the upper end fixing piece 2 of the side wall 1, and on the one hand enters the upper space of the room through the first partition hole 204 and the first fan 201, and on the other hand flows into the lower end fixing piece 3 through the side circulation space 101 inside the side wall 1. At this time, since the second outer hole valve 309 on the outside of the lower end fixing piece 3 is closed, the gas flows into the lower space of the room through the second partition hole 304 and the second inner hole 302, and since all the valves on the remaining side walls 1 are open, the indoor gas flows out through the upper end fixing piece 2 and the lower end fixing piece 3 of the remaining side walls 1, thereby realizing indoor ventilation and sufficient exchange of indoor and outdoor gases. At this time, the input gas intensity at the lower end of the side wall 1 is weaker than the input gas intensity at the upper end.

[0050] Mode 2: The second outer hole valve 309 on the outer side of the lower end fixing part 3 of the side wall 1 equipped with the first fan 201 is closed, and the first partition valve 205 in the upper end fixing part 2 is also closed, and the remaining valves of the side wall 1 are opened, and the valves on the remaining side walls 1 are also opened.

[0051] After the first fan 201 is started, outdoor fresh air flows in through the first outer hole 202 on the outside of the upper end fixing piece 2 of the side wall 1. Since the first partition valve 205 on the upper end of the side wall 1 is closed, the gas can only flow downward along the side circulation space 101 on the outside of the side wall 1 and enter the lower end fixing piece 3. After entering the lower end fixing piece 3, the gas passes through the second partition hole 304 and the second inner hole 302 to enter the lower part of the room on the one hand, and flows upward through the side circulation space 101 on the inner side of the side wall 1 and enters the upper part of the room through the first fan 201 on the other hand. The indoor gas flows out through the upper end fixing piece 2 and the lower end fixing piece 3 of the remaining side walls 1, which can also realize indoor ventilation and sufficient exchange of indoor and outdoor gases. At this time, the input gas intensity at the lower end of the side wall 1 is stronger than that at the upper end, and the incoming air can be fully filtered by the pad assembly 4 to ensure the cleanliness of the input gas.

[0052] Mode three: the second outer hole valves 309 outside the fixing members 3 at the lower ends of the side walls 1 are all closed, and the remaining valves are all opened.

[0053] After the first fan 201 is started, the outdoor fresh air flows in through the first outer through hole 202 on the outside of the upper end fixing member 2 of the side wall 1, and enters the upper space of the room through the first partition through hole 204 and the first fan 201 on the one hand, and flows into the lower end fixing member 3 through the side circulation space 101 in the side wall 1 on the other hand, and flows into the lower space of the room through the second partition through hole 304 and the second inner through hole 302. Since the second outer hole valve 309 on the outside of the lower end of the remaining side wall 1 is closed, the indoor gas enters the remaining side wall 1 and flows out from the upper end of the side wall 1 after passing through the side circulation space 101, so that the purpose of cooling and heating all walls can be achieved. At this time, the input gas intensity at the lower end of the side wall 1 is weaker than the input gas intensity at the upper end.

[0054] In this mode, the first partition valve 205 in the upper end fixing part 2 of the side wall 1 where the first fan 201 is provided can also be closed at the same time. After the gas enters, it can only enter the lower end fixing part 3 through the side circulation space 101, and then on the one hand, it goes upward through the first fan 201 to enter the upper part of the room, and on the other hand, it directly enters the upper part of the room from the lower end of the side wall 1. At this time, the gas input strength at the lower end of the side wall 1 is stronger than the gas input strength at the upper end, and the air can be fully filtered through the pad assembly 4.

[0055] In this embodiment, only the upper valve of the side wall 1 provided with the first fan 201 can be opened to input gas only from the upper end, or only the lower valve of the side wall 1 can be opened to input gas only from the lower end. However, if there are a lot of impurities in the outdoor air, it is necessary to close the first partition valve 205 or the second partition valve 305 according to the situation to ensure that the gas bends and flows through the pad assembly 4 for filtration before entering the room after being input. Different modes can be selected according to actual needs.

[0056] Embodiment 2:

[0057] like Figure 7 As shown, the difference between this embodiment and the first embodiment lies in that: a first fan 201 is provided on the inner side of the upper end of at least one side wall 1, and a second fan is provided on the inner side of the upper end of the side wall 1 on the opposite side, and the first fan 201 is for induced air, and the second fan is for exhaust air, thereby accelerating the exchange of indoor and outdoor air circulation, and in addition, the lower end fixing piece 3 of each side wall 1 is only provided with a second inner through hole 302 with a second inner hole valve 303 on the inner side, and the outer side is a closed structure.

[0058] The working mode of this embodiment is the same as that of the first embodiment, the only difference being that a second fan with exhaust function is added to accelerate the exchange rate of indoor and outdoor air circulation.

[0059] In this embodiment, a second outer through hole 308 with a second outer hole valve 309 may be provided on the outer side of the lower end fixing member 3, and all the second outer hole valves 309 can be closed during operation.

[0060] Embodiment three:

[0061] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that a first inner hole valve is provided at the first inner through hole at the inner end of the upper end fixing member 2 of each side wall 1, eliminating the air induction function of the fan. This embodiment mainly relies on the internal and external pressure difference formed by the outdoor wind or the indoor and outdoor temperature difference to achieve natural air intake exchange, and the working mode is the same as that of the first embodiment.
