Through the operation, the user can observe the deicing condition conveniently, the trouble that the user can observe the deicing condition and continue deicing due to the fact that the user waits for mist to spontaneously disperse is avoided, and the deicing efficiency is high.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
