    •  DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIG. 1 and FIG. 2, the figures show a ventilation device used in a bathroom. The ventilation device comprises a housing (1) having an receiving space (11) disposed therein, an air inlet (12) and an air outlet (13) disposed at both sides of the receiving space (11) and communicating with the receiving space (11), a baffle piece (131) pivotally disposed at the air outlet (13), and a bottom cover (14) disposed at a bottom of the housing; a fan module (3) detachably disposed in the receiving space (11) of the housing (1) and fastened to the positioning member (2); and a power control device (4) disposed in the receiving space (11) with its shell connected to the inner wall corresponding to the housing (1) in a detachable manner. The power control device (4) is electrically connected with the fan module (3), and has a wire-arranging element (41) for fixing the electric wires of the fan module (3).
  • With the design of fastening the fan module (3) to the positioning member (2) in a detachable manner, a user can push the fan module (3) to slide the fan module (3) from the side edge of the positioning member (2) and remove out of the housing (1) to allow repair and maintenance more simple and convenient.
  • The above two figures also show that the power control device (4) can be connected to the inner wall corresponding to the housing (1) by using magnet (5) in a magnetic attraction manner. Of course, in addition to using magnet (5) in a magnetic attraction manner, hooking (not shown in the figure) or adhering (not shown in the figure) may also be used for connecting to the inner wall corresponding to the housing (1). As a result, the installed power control device (4) can be more firmly fixed and will not be fell off in removing the bottom cover (14) of the housing (1) during maintenance. In addition, through the methods of magnetic attraction, hooking (not shown in the figure) or adhering (not shown in the figure), there is no need to use screws for connection between the power control device (4) and the housing (1), which not only simplifies the structure, but also makes the installation easier.
  • As shown in FIG. 2, the wire-arranging element (41) is disposed at one side edge of the power control device (4), and is a non-closed loop hook for fixing the electric wires of the fan module inside. The top of one fixing pieces (311) is inwardly recessed with a receiving groove (313) for receiving the electric wire of the fan module (3). Therefore, through the collaboration of wire-arranging element (41) and receiving groove (313), the electric wires between the fan module (3) and the power control device (4) can be fixed to achieve good wire-arranging effect and solve the problem of electric wire storage.
  • As shown in FIG. 2a to FIG. 4, one end of the fan module (3) further has a motor (31) fastened and fixed 10 positioning member (2). A plurality of fixing pieces (311) is disposed around the outer edge of the motor (31). One end of each fixing member (311) has a snap slot (312) which is disposed corresponding to the positioning member (2) and can be fastened to the positioning member (2). Accordingly, when the motor (31) is disassembled, the motor (31) only needs to be pushed to slide the snap slot (312) out of the side edge of the positioning member (2). Conversely, when the motor (31) is installed, the snap slot (312) only needs to be embedded in the positioning member (2) in a slide way to improve the convenience and save the time of assembly and disassembly.
  • The above only describes some exemplary embodiments of the present invention. Those having ordinary skills in the art may also make many modifications and improvements without departing from the conception of the invention, which shall all fall within the protection scope of the invention.
