The inner surface of the bottom of the chamber is provided with a plurality of supporting bosses. One outer edge of the control circuit board inserts into the gap, which enables the outer side surface of the control chip to cling to the inner side surface of the heat dissipation boss. The control circuit board is supported by upper surfaces of the supporting bosses.
