Description

A shells assembly, new fan for new fan Technical Field The application relates to the technical field of air conditioning, in particular to a shell assembly for a fresh air machine and the fresh air machine. Background At present, the fresh air device is an effective air conditioning device, can discharge indoor dirty air outdoors, and can introduce outdoor fresh air indoors so that the room is fresh air at all times. A single hole type heat exchanger is disclosed in the related art in which a grill is used to open and close a tuyere. The host machine comprises a grid mounting piece capable of driving the grid to open and close, a wax motor capable of driving the grid mounting piece to move, and a spring piece capable of pushing the grid mounting piece to reset. In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: The wax motor needs to utilize the shell fragment to realize resetting when working. However, the elastic sheet has a limited service life, and is easy to fatigue, deform and even damage in the long-term use process. Once the elastic sheet is damaged, the opening and closing functions of the grille are affected, so that the equipment cannot normally operate, and the maintenance cost and the fault risk of the equipment are increased.
