The silencer duct cover 105 is rotated so that it covers the upper surface of the housing 101. At this time, the position between the silencer duct cover 105 and the housing 101 matches, and no further adjustment is required.

[0028] In one embodiment, such as Figure 1 As shown, a rubber pad 107 is provided at the contact surface between the housing 101 and the noise-absorbing air duct 105, which fills the small gap between the noise-absorbing air duct 105 and the housing 101, thus helping to reduce noise.

[0029] In one embodiment, such as Figure 2 and Figure 5 As shown, the anti-loosening fixing structure includes a stud 301 connected to the housing 101. The silencer vent 105 has an installation groove 302 corresponding to the position of the stud 301. An anti-loosening washer is fitted on the stud 301. An installation nut 305 is threadedly connected to the stud 301. The housing 101 is provided with a tensioning component to restrict the loosening of the anti-loosening washer. The anti-loosening washer includes an anti-loosening block 303. A first toothed block 401 is provided around the anti-loosening block 303. A nut groove 304 is provided on the anti-loosening block 303. The installation nut 305 matches the nut groove 304. Rotating the installation nut 305 presses the anti-loosening block 303, and the anti-loosening block 303 presses the silencer vent 105 onto the housing 101. When the installation nut 305 rotates, the anti-loosening block 303 rotates synchronously with the installation nut 305 due to the action of the nut groove 304.

[0030] In one embodiment, such as Figure 2 and Figure 5As shown, the tensioning assembly includes a first fixing plate 402 connected to the silencer vent 105. A sliding frame 403 is slidably mounted on the first fixing plate 402. Second toothed blocks 404 are arranged in a linear array on the side of the sliding frame 403 near the stud 301. The second toothed blocks 404 cooperate with the first toothed blocks 401. One end of the sliding frame 403 is connected to one end of the spring 503 through a snap-fit ​​assembly.

The pulling module includes a pull rod 501 hinged to the silencer vent 105. The pull rod 501 is hinged to the connecting block 502. A second fixing plate 601 is connected to the silencer vent 105. The second fixing plate 601 is provided with a limiting groove 602. A limiting block 603 is rotatably connected in the limiting groove 602. There is sliding damping between the sliding frame 403 and the first fixed plate 402. When installing the mounting nut 305, the snap-fit ​​block 504 disengages from the slot 505, and there is no contact between the second toothed block 404 and the first toothed block 401. After tightening the mounting nut 305, pull down the sliding frame 403 to make the first toothed block 401 and the second toothed block 404 engage, snapping the snap-fit ​​block 504 into the slot 505. Pull the pull rod 501, and the pull rod 501 touches the limiting block 603, causing the limiting block 603 to rotate and create space. After the pull rod 501 passes through, the limiting block 603 is pulled out and the pull rod 501 is released. Under the action of the limiting groove 602, the limiting block 603 limits the pull rod 501. At this time, the pull rod 501 stretches the spring 503 through the connecting block 502. The spring 503 pulls the sliding frame 403 through the snap block 504 and the snap groove 505. The second tooth block 404 on the sliding frame 403 acts on the first tooth block 401 to prevent the anti-loosening block 303 from loosening, that is, to prevent the installation nut 305 from loosening, thus achieving the anti-loosening effect.

[0031] The above embodiment discloses an air source heat pump heating component, wherein, while the exhaust fan 104 discharges air from the housing 101, outside air enters the housing 101 through the vent 103. The air source heat pump heating structure 102 consumes electrical energy to convert low-grade heat energy in the air into high-grade heat energy for heating. When installing the silencer vent 105, first align the rotating sleeve 203 with the connecting post 202 and put the rotating sleeve 203 on the connecting post 202 for easy positioning. Rotate the silencer vent 105 so that it covers the upper surface of the housing 101. At this time, the position between the silencer vent 105 and the housing 101 matches and no further adjustment is needed. Then, first put the anti-loosening block 303 on the stud 301, and then screw the mounting nut 305 on the stud 301. When installing the mounting nut 305, the locking block 504 disengages from the slot 505, and the second tooth block 404 engages with the first There is no contact between the toothed blocks 401. After tightening the mounting nut 305, the silencer vent 105 is fixed. Pull down the sliding frame 403 to make the first toothed block 401 and the second toothed block 404 engage. Insert the snap-fit ​​block 504 into the snap-fit ​​slot 505. Pull the pull rod 501. The pull rod 501 touches the limit block 603. The limit block 603 rotates to make room. After the pull rod 501 passes, it pulls out the limit block 603 and releases the pull rod 501. 1. Under the action of the limiting groove 602, the limiting block 603 limits the pull rod 501. At this time, the pull rod 501 stretches the spring 503 through the connecting block 502. The spring 503 pulls the sliding frame 403 through the snap block 504 and the snap groove 505. The second tooth block 404 on the sliding frame 403 acts on the first tooth block 401 to prevent the anti-loosening block 303 from loosening, that is, to prevent the installation nut 305 from loosening, thus achieving the anti-loosening effect.
