And the number of the heat dissipation fans 80 may be one or more, and here, the number and the arrangement position of the heat dissipation fans 80 are not limited.

As described above, referring to fig. 3, in some embodiments of the present invention, when the heat dissipation fan 80 is disposed on the inner bottom surface of the housing 20, the ventilation opening 41 may be located right above the heat dissipation fan 80, so as to prevent heat in the first air duct 22 from being brought into the second air duct 23. In addition, a heat insulator 42 may be provided in the vent 41, and the heat insulator 42 may be connected to the heat insulating sheet 40, but of course, the heat insulating sheet 40 may be integrally formed with the heat insulating sheet 40, and "integrally formed" means that the two members are processed together to form an integral body which is inseparable.

The heat insulation member 42 is disposed on the motor 81 of the heat dissipation fan 80 (as shown in fig. 2), so that heat generated by the motor 81 of the heat dissipation fan 80 during operation can be reduced to enter the first air duct 22 and the second air duct 23, thereby reducing temperature rise in the accommodating chamber 21.
