[0030] The projection module 32 is in communication connection with the magnetic field preservation module 31 , and is used for projecting a projection pattern representing the working state of the magnetic field preservation module 31 .

[0031] In a specific embodiment, when the magnetic field preservation module 31 generates a magnetic field (i.e., powered on and in working state), the projection module 32 projects a first pattern, and when the magnetic field preservation module does not generate a magnetic field (i.e., powered off and not working), the projection module 32 projects a second pattern. The first pattern and the second pattern can be static patterns or dynamically changing patterns.

[0032] For example, in a specific embodiment, the first pattern is disordered light spots, and the second pattern is ordered light spots. When the magnetic field preservation module 31 switches from a non-operating state to a working state (i.e., from power off to power on), the pattern projected by the projection module 32 changes from disordered light spots to ordered light spots, thereby showing a dynamic effect.

[0033] In one embodiment, the projection module 32 can also project more than two patterns, for example, three or four patterns, etc. For example, the projection module can project patterns corresponding to "running", "not running", "abnormal", and patterns corresponding to different fresh-keeping strengths or magnetic field strengths such as "first gear", "second gear", "third gear", etc. The pattern can be a text pattern, and the present application does not limit the specific shape of the pattern projected by the projection module.
