[0029] During use, the refrigerant sensor is located in the installation cavity 213 and connected to the top plate 211, and the installation bracket 22 is connected to the chassis of the air conditioning unit.

[0030] In this embodiment, the waterproof cover 21 can be injection molded or assembled in parts. When the waterproof cover 21 is assembled in parts, the top plate 211 and the eaves 212 are welded to improve the sealing performance.

[0031] The sensor mounting structure 20 of the embodiment of the utility model includes a waterproof cover 21 and a mounting bracket 22.
