[0024] Embodiment one, by Figure 1 The utility model relates to a kind of air source heat pump unit protective devices, including protective box 1, box door 3 is hinged on the outside of protective box 1, air source heat pump unit body 4 is equipped in the inside of protective box 1, two heat dissipation fans 5 are symmetrically installed on the inner top wall of protective box 1, two heat dissipation fans 5 are all located above air source heat pump unit body 4, heat dissipation port 6 is equipped in the top of protective box 1, filter mechanism 2 is equipped in the top of protective box 1.

[0025] Specifically, by Figures 2-5The filter mechanism 2 includes a heat dissipation frame 201 fixed to the top of the protective box 1. The heat dissipation frame 201 is located at the heat dissipation vent 6 and communicates with the interior of the protective box 1 through the heat dissipation vent 6. A filter plate 203 is fixedly connected inside the heat dissipation frame 201, and the left end face of the filter plate 203 is flush with the left end face of the heat dissipation frame 201. A U-shaped frame 204 is fixedly connected to the top of the heat dissipation frame 201. An inner shaft 205 is rotatably connected to the inner side of the U-shaped frame 204. A protective plate 202 is fixedly sleeved on the outer side of the inner shaft 205. The protective plate 202 is inclined. Two L-shaped round rods 207 are symmetrically fixedly connected between the outer side of the U-shaped frame 204 and the top of the protective box 1. A lifting plate 206 is movably sleeved, and an installation plate 2014 is provided on the outer side of the lifting plate 206. A cleaning brush 2013 is fixedly connected to the side of the installation plate 2014 away from the lifting plate 206. The cleaning brush 2013 is in contact with the filter plate 203. Two outer rings 209 are symmetrically provided above the lifting plate 206. The two outer rings 209 are fixedly sleeved on the outer side of two L-shaped round rods 207 respectively. A return spring 208 is fixedly connected between the two outer rings 209 and the lifting plate 206. The two return springs 208 are respectively sleeved on the outer side of the two L-shaped round rods 207. A drive rod 2010 is rotatably connected to the top of the lifting plate 206. The top end of the drive rod 2010 is rotatably connected to the protective plate 202.

[0026] In use, a protective plate 202 is first installed on the outside of the filter plate 203 to shield and protect the filter plate 203. When the protective plate 202 is impacted, it rotates with the inner shaft 205. The driving rod 2010 drives the lifting plate 206 to slide down along the two L-shaped round rods 207. At this time, both return springs 208 are deformed and buffer the protective plate 202 under the elastic force of the two return springs 208. At the same time, the cleaning brush 2013 moves down to clean the surface of the filter plate 203. Finally, the filter plate 203 is cleaned to prevent it from becoming clogged.

Finally, when the lifting plate 206 descends, the cleaning brush 2013 is in constant contact with the filter plate 203, ensuring the cleaning effect on the filter plate 203.
