The left end of the cabinet door 11 is rotatably connected with the left end of the outer shell 4 through a hinge, and the cabinet door 11 can be opened and closed through the arrangement. The inner side of the bottom end of the outer shell 4 is fixedly connected with a telescopic rod 2. The top end of the telescopic rod 2 is fixedly connected with an inner shell 6. The outside of telescopic link 2 is provided with first spring 3, and the both ends of first spring 3 are connected with the bottom inboard of shell body 4 and the bottom fixed connection of interior casing 6 respectively, and this kind of setting is in order to support the partial weight of interior casing 6. The bottom end of the inner housing 6 is provided with an air inlet 15, which is arranged to keep the inside of the inner housing 6 ventilated.

And the inner sides of the left end and the right end of the outer shell 4 are both provided with positioning beads 5. The inboard and the right-hand member inboard of the left end of shell body 4 all are provided with second spring 13, and the both ends of second spring 13 respectively with the inboard fixed connection of one end of locating ball 5 and the one end of shell body 4, the inboard fixed connection of left end of interior casing 6 has controller 10. The inner side of the right end of the inner shell 6 is fixedly connected with a temperature sensor 14. Air outlet 16 has all been seted up to the top inboard of interior casing 6 and shell body 4, is located the inboard fixedly connected with connecting rod 7 of the right-hand member of the air outlet 16 of downside. The left end fixedly connected with fan 8 of connecting rod 7, and fan 8 is located the inboard of air outlet 16. The top end of the outer shell 4 is fixedly connected with a rain-proof plate 9, and the arrangement is used for preventing rainwater from entering. The inner side of the bottom end of the cabinet door 11 is connected with a dust filter screen 1 in a sliding mode, and the inner sides of the left end and the right end of the dust filter screen 1 and the inner side of the cabinet door 11 are both connected with fixing bolts 12 in a spiral mode.

The quantity of fixing bolt 12 is 2, and the symmetric distribution can make dust filter screen 1 firmly fixed at dust filter screen 1's left and right sides both ends, and can dismantle and change. The number of the telescopic rods 2 and the first springs 3 is 2, and the telescopic rods and the first springs are symmetrically distributed at the bottom end of the inner shell 6, and the arrangement can support part of gravity of the inner shell 6 in a balanced manner.
