Abstract: A water supply device (10) and a tube connector structure (2) thereof, which are used for an electronic device (100) having a water inlet (101) and a water outlet (102), are disclosed. The tube connector structure (2) includes a connecting plate (21) and two tube connector plugs (22) passing through and fixed to the connecting plate (21). One of the tube connector plugs (22) is connected with the water inlet (101), and the other one of the tube connector plugs (22) is connected with the water outlet (102). Therefore, advantages of rapid connection and disconnection between the water supply device (10) and the tube connector structure (2) and saving time and labor in assembling may be accomplished.

Abstract: A multifunction expansion device includes a driving unit, an expansion unit and a connecting unit. The multifunction expansion device is characterized that, the expansion unit is electrically connected to the driving unit and the connecting unit. The expansion unit further includes an input and output device and a signal device. The input and output device is provided with a plurality of connecting pins, and allows a plurality of connecting pins to enable corresponding connection and transmission through connecting pin combinations in different quantities and operating with the signal device. Accordingly, by utilizing various combinations of idle connecting pins and operating with the signal device, the expansion unit allows the driving unit to operate devices of the connecting unit, thereby allowing the expansion module to correspond with various devices.
