Claim 6:
7. A mouth mirror apparatus comprising:
a handheld module including
a carrier seat that has
a surrounding wall surrounding an axis,
a mounting wall extending transversely to the axis, and surrounded by and connected to said surrounding wall, said surrounding wall and said mounting wall cooperatively defining
first and second receiving spaces which are disposed on two sides of said mounting wall that are opposite along the axis, and
a plurality of air outlet passages which are embedded angularly at intervals in said surrounding wall, and each of which has a first passage open end communicating with said first receiving space and a second passage open end communicating with said second receiving space, and

a base cover covering an opening of said second receiving space, and being connected to said surrounding wall, and

a handle grip that is transversely connected to an outer surface of said surrounding wall, and that cooperates with said surrounding wall to define an air inlet passage in spatial communication with said second receiving space; and

a rotating mirror module including
a mirror unit that has
a mirror body disposed in said first receiving space transversely to the axis, and being rotatable about the axis relative to the carrier seat, and
a rotary shaft extending through said mounting wall along the axis, and co-rotatably connected to said mirror body, and

an impeller that has
a connecting hub disposed in said second receiving space, and co-rotatably connected to said rotary shaft, and
a plurality of fan blades arranged angularly about the axis in said second receiving space, and co-rotatably connected to said connecting hub, said fan blades being adapted to be driven by air, which travels through said air inlet passage into said second receiving space, to drive rotation of said mirror body of said mirror unit relative to the carrier seat;, wherein:
said connecting hub of said impeller has an insertion segment that is configured as a truncated cone; and
said rotary shaft of said mirror unit is formed with a shaft recess that complementarily receives said insertion segment of said connecting hub of said impeller.
