An air conditioner windscreen limiting device according to claim 1 wherein said bearing seat comprises a first seat bore, the elastic component is a spring, the magnetic component comprises a rod part and a limiting block, the rod part is arranged in the first seat hole in a penetrating mode, the limiting block is connected to the rod part or is integrally made with the rod part and is positioned outside the first seat hole, the spring is sleeved on the rod part and positioned between the first seat hole and the limiting block, one end of the spring is fixedly connected or abutted with the outer wall surface of the first seat hole, the other end of the spring is fixedly connected or abutted with the limiting block, the spring is compressed in the process that the magnetic component is adsorbed to the electromagnetic component, so that the magnetic member can be driven to extend out of the supporting seat by means of the acting force for restoring the deformation in the state that the electromagnetic member is powered off.
9. An air conditioner windscreen limiting device according to any one of claims 1 to 8 wherein the air conditioner includes a fan and the securing formation is a volute tongue of the fan.
10. An air conditioner windscreen limiting device according to any one of claims 1 to 8 wherein the snap-fit formation is a limiting recess formed in the windscreen into which an end of the projecting magnetic member can engage.
