[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0024] like Figure 1 and Figure 2 As shown, an air energy heat pump device includes a casing 20. The casing 20 is in the shape of a hollow rectangular box with an opening on the front wall. A fan 21 is rotatably connected to the cavity of the casing 20. A compressor for heating is also installed in the cavity of the casing 20. There is a distance between the compressor and the bottom of the cavity 20. The fan 21 and the compressor are both electrically connected to a power supply. This is an existing technology and will not be described in detail here.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a rainproof structure is provided in the cavity of the casing 20, and the rainproof structure includes a front plate 32 and a ventilation slot 33. The front plate 32 is fixedly connected to the opening of the front wall of the casing 20, and the ventilation slot 33 is opened on the wall of the front plate 32. The rainproof structure can prevent rainwater from entering the cavity of the casing 20. The rainproof structure also includes a rotating column 30 and a bottom plate 31. The rotating column 30 is rotatably connected to the bottom of the cavity of the casing 20, and the bottom plate 31 and the rotating column 30 are fixedly connected.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front plate 32 can block the front wall opening of the casing 20, the ventilation slot 33 is a parallelogram-shaped slot, a plurality of ventilation slots 33 are provided on the wall of the front plate 32, and the plurality of ventilation slots 33 are evenly distributed on the wall of the front plate 32, the bottom of the cavity of the casing 20 is sloped, a rectangular slot is also provided on the bottom of the cavity of the casing 20, the rotating column 30 is located in the rectangular slot, the bottom plate 31 is fixedly connected to the rotating column 30 in the rectangular slot, and the bottom plate 31 can block the rectangular slot at the bottom of the cavity of the casing 20;

[0027] In specific use, when the casing 20 is installed on the outer wall of the building, if the bottom of the casing 20 is suspended, the bottom plate 31 will flip ninety degrees due to gravity, and the rectangular groove at the bottom of the casing 20 is open. If the bottom of the casing 20 is on the ground, the bottom plate 31 will cover the rectangular groove at the bottom of the casing 20. When rain falls from the sky to the wall of the front plate 32, the rain will not penetrate into the cavity of the casing 20 from the ventilation groove 33, but will flow directly downward along the outer wall of the front plate 32, and air can enter the cavity of the casing 20 from the ventilation groove 33. When there is water in the cavity of the casing 20, the water will flow along the sloped cavity of the casing 20 to the wall of the bottom plate 31. If the bottom plate 31 is in a flipped state at this time, it will flow out of the casing 20 from the rectangular groove of the casing 20.

[0028] In summary, by setting up a rainproof structure, rainwater can be prevented from affecting the operation of the structure inside the casing 20 cavity, because the rainproof structure achieves the effect of both ventilation and rainproof through the special structure of the front panel 32 and the ventilation groove 33, thereby preventing rainwater from affecting the operation of the structure inside the casing 20 cavity. Therefore, compared with the existing technology, this solution has a longer lifespan and is safer when used.

[0029] like Figure 2 and Figure 5 As shown, a dustproof structure is also provided in the cavity of the casing 20, and the dustproof structure includes a filter plate 40, a mesh slot 41, a filter screen 42, a through slot 43, a connecting column 44, a swing rod 45 and a brush 46. The filter plate 40 is fixedly connected to the cavity of the casing 20, the mesh slot 41 is opened on the wall surface of the filter plate 40, the filter screen 42 is fixedly connected in the mesh slot 41, the through slot 43 is opened on the wall surface of the filter screen 42, the connecting column 44 is fixedly connected to the front wall surface of the fan 21, and the swing rod 45 is fixedly connected to the front wall surface of the fan 21. The wall surface of the connecting column 44, the brush 46 is fixedly connected to the rear wall surface of the swing rod 45, a plurality of filters 42 are fixedly connected in the net slot 41, and the plurality of filters 42 are distributed in a circular array in the net slot 41, and the through slot 43 is opened at the center position of the plurality of filters 42, and the through slot 43 is a circular slot, the connecting column 44 is cylindrical, and the connecting column 44 can pass through the through slot 43, the swing rod 45 is fixedly connected to the arc surface of the connecting column 44, and the brush 46 can contact the front wall surface of the filter 42;

[0030] In specific use, when the fan 21 rotates, the connecting column 44 is driven to rotate, and when the connecting column 44 rotates, the swing rod 45 and the brush 46 are driven to rotate at the same time. The brush 46 contacts the filter 42 during rotation, and the brush 46 is a brush made of soft material.

[0031] To sum up, by setting up a dust-proof structure, it is possible to prevent dust and clean the filtered dust at the same time. Because the dust-proof structure filters the dust through the filter 42 and when the power of the fan 21 is turned on, it will drive the brush 46 through the connecting column 44 to sweep away the dust attached to the wall of the filter 42, thereby preventing dust from affecting the working efficiency of the device and increasing the service life of the device.

[0032] Working principle: When the casing 20 is installed to the outer wall of the building, if the bottom of the casing 20 is suspended in the air, the bottom plate 31 will flip ninety degrees due to gravity. At this time, the rectangular groove at the bottom of the casing 20 is in an open state. If the bottom of the casing 20 is on the ground, the bottom plate 31 will block the rectangular groove at the bottom of the casing 20. When rain falls from the sky to the wall of the front plate 32, the rain will not penetrate into the cavity of the casing 20 from the ventilation groove 33, but will flow directly downward along the outer wall of the front plate 32, and the air can enter the cavity of the casing 20 from the ventilation groove 33. When there is water accumulated in the cavity of the casing 20, the accumulated water will flow along the sloped cavity of the casing 20 to the wall of the bottom plate 31. If the bottom plate 31 is in a flipped state at this time, it will flow out of the casing 20 from the rectangular groove of the casing 20.
