[0043] Working principle: The outdoor air enters the low-energy building fresh air machine body 1 through the outdoor air inlet pipe 2. In the indoor air inlet pipe 2, the filter screen 302 on the fixed ring 301 plays a preliminary filtering role. The filter screen 302 is tightly connected with the fixed ring 301. The fixed ring 301 is installed through the clamping block 303 and the connecting plate 304. The fixed ring 301 is movably inserted into the opening 5 of the outdoor air inlet pipe 2. The sealing ring 7 on the top of the clamping block 303 ensures the sealing of the connection to prevent unfiltered air from entering the gap. The larger dust in the outdoor air is intercepted by the filter screen 302, thereby avoiding the direct entry of these large particles into the low-energy building fresh air machine body 1 and contacting the filter core inside the low-energy building fresh air machine body 1, reducing the filtering burden of the filter core inside the low-energy building fresh air machine body 1, reducing the replacement frequency of the filter core inside the low-energy building fresh air machine body 1, reducing the use cost, avoiding the problem that the existing part of the low-energy building fresh air machine does not have a preliminary filtering structure at the outdoor air inlet, which is not convenient for preliminary filtering of the larger dust in the outdoor air. The larger dust in the outdoor air directly enters the low-energy building fresh air machine and contacts the filter core. Since the filter core of the low-energy building fresh air machine is mainly used for fine filtering, such as removing PM2.5, pollen, bacteria and other small particles, the larger dust in the outdoor air is easy to cause the blockage of the filter core, affecting the filtering effect of the outdoor air, and consuming a large amount of filter core, increasing the replacement frequency and improving the use cost. When the filter screen 302 needs to be cleaned, the first limiting button 13 is disassembled. The first limiting button 13 is connected with the limiting block 12 through the internal thread. When the first limiting button 13 rotates, the first limiting button 13 moves. The first limiting button 13 is moved away from the fixed rod 8. The connecting plate 304 and the fixed ring 301 are pulled out of the outdoor air inlet pipe 2. Then the pull ring 9 is held and rotated. The rotating plate 601 is movably sleeved on the surface of the fixed column 10 through the rotating ring 603, so that the bristles 602 can brush and clean the dust on the surface of the filter screen 302. The filter screen 302 can be reused. The second limiting button 604 is disassembled. The second limiting button 604 is connected with the fixed column 10 through the internal thread. When the second limiting button 604 rotates, the second limiting button 604 moves. The second limiting button 604 is moved away from the fixed column 10. The rotating ring 603 and the rotating plate 601 are disassembled. It is convenient to clean the bristles 602 and clean the filter screen 302 quickly and conveniently. It is convenient to use. It should be noted that the low-energy building fresh air machine body 1 is a mature technology that has been published. The low-energy effect has been achieved. Here is not described.
[0044] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
