DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a surfboard, and more particularly to an electric surfboard. [Prior Art] Fig. 1 shows a conventional electric surfboard comprising a plate body U extending in a long direction and floating on water, a driving device 12, a rear end adjacent to the plate body and from the plate body 11 a balance bar 13 extending upwardly from the top, and an operating handle 14 disposed at an upper end of the balance bar 13. The driving device 12 includes a motor m disposed at the rear end of the plate body u and located below the water surface, and a pusher 122 disposed on the motor 121 and located below the water surface. The operating handle 14 is coupled to the motor 121 and controls the rotational speed of the motor 121. The motor 121 drives the pusher 122 to rotate about its axis relative to the plate H to urge the plate to advance. When the electric surfboard 1 is in the absence of wind or no waves, the board U can be pushed by the driving device 12, but the driving device 12 is mounted outside the board 11, so the electric surf board 丨In addition to the resistance of the plate body 11 in the water (same size as the resistance of the conventional surfboard in water), it is necessary to additionally withstand the resistance of the driving device 12 in the water, and thus has a large loss of resistance in the water. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an electric surfboard that can reduce the resistance of water in the water. Thus, the electric surfboard of the present invention is suitable for floating on water and advancing, and 5 200831353 comprises a plate unit, a driving device and a control unit. The plate unit may float on the water and include a longitudinally extending plate body having a first-class passage and a receiving groove formed on a top surface and extending toward a bottom surface. The flow passage has an input port formed on the bottom surface of the plate body and supplied with water, and an output port formed at the rear end of the plate body and supplied with water. The driving device includes a motor unit disposed in the plate unit and a propeller located in the flow channel. The motor unit drives the propeller to rotate about its own axis relative to the plate unit to push the plate unit into engagement. The control unit includes a controller located in the accommodating slot and a battery. The controller electrically connects the motor unit and controls the rotational speed of the motor unit. The battery is electrically connected to the controller. The effect of the electric surfboard of the present invention is that the drive unit is located within the panel unit' so that there is no need to additionally withstand the resistance of the drive unit in the water, thus having the advantage of less water resistance. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figures 2, 3 and 4, a first preferred embodiment of the electric surfboard of the present invention is adapted to float on water and advance, and includes a panel unit 2, a drive unit 3 and a control unit 4. The plate unit 2 can float on the water and includes a longitudinally extending plate 6 200831353 body 21, a fixing base 22 and an upper cover 23. The plate body 21 has a flow passage 211 and a receiving groove 212 formed on a top surface and extending toward a bottom surface. The flow passage 211 has an inlet port 213 formed in the bottom surface of the plate body 21 for the inflow of the jug, and an outlet port 214 formed at the rear end of the plate body 21 and supplied with water. The fixing seat 22 is disposed in the flow channel 211 and adjacent to the rear end of the plate body 21 and located between the input port 213 and the output port 214. The upper cover 23 seals the receiving groove 212. The drive unit 3 includes a motor unit 31 disposed within the board unit 2, and a propeller 32 located within the flow passage 211. The motor unit 31 has a motor 311 disposed in the plate body 21, and a coupling 312 extending through the fixing base 22 and connecting the propeller 32 and the motor 311. The motor 311 can rotate the coupling 312 relative to the fixing base 22. The coupling 312 drives the propeller 32 to rotate about its own axis with respect to the plate unit 2 to push the plate unit 2 forward. The control unit 4 includes a controller 41 located in the accommodating slot 212, a battery 42, an operating member 43 outside the board unit 2, and a connection between the operating member 43 and the controller 41. In line 44, the controller 41 is electrically coupled to the motor unit 31 and controls the rotational speed of the motor unit 31. The battery 42 is electrically coupled to the controller 41. In summary, the electric surfboard of the present invention has the effect that when the ocean wave is generally absent, the board unit 2 can be propelled not only by the driving device 3, but also ί = 2 3 is disposed in the board body 21, so the electric surfing The board only needs ρ and ^ 21 resistance in the water, similar to the traditional surfboard in the water 'thus so it can really reduce the resistance in the water. 7 200831353 Referring to FIG. 5, a second preferred embodiment of the electric surfboard of the present invention is substantially the same as the first preferred embodiment, except that the electric surfboard further includes a balancing unit 5, and the balancing unit 5 includes two The connecting rods 51 respectively extending outward from the opposite sides of the plate body 21, and two pontoons 52 respectively disposed at opposite ends of the connecting rod 51 opposite to the plate body 21. Thereby, in addition to the effect described in the first preferred embodiment, the balancing unit 5 increases the area in which the whole body floats, and makes the plate body 21 difficult to overturn, so that the beginner is more likely to learn and use. Referring to FIG. 6, a third preferred embodiment of the electric surfboard of the present invention is substantially the same as the first preferred embodiment, except that the electric surfboard further includes a balance unit 6, and the balance unit 6 includes a proximity A support rod 61 having a front end of the plate body 21 and extending obliquely upward from the top surface of the plate body 21, and a hand grip rod 62 substantially perpendicular to the branch rod 61 and disposed at the top end of the branch rod 61. The control unit 4 includes a controller 41, a battery 42 (shown in Figure 3), and an operating member 45 disposed on the hand grip 62 and controlling the controller 41 in a wireless Bluetooth communication protocol. Thereby, in addition to the efficiencies described in the first preferred embodiment, the arrangement of the balancing unit 6 and the controller 41 makes it easier for the electric surfboard to control balance and speed. Referring to Figure 7, a fourth preferred embodiment of the electric surfboard of the present invention is substantially the same as the first preferred embodiment, except that the electric surfboard further includes a sail list 70 7 'the sail unit 7 includes - set A sail frame 71 on the top surface of the plate unit 2, and a sail 72 disposed on the sail frame 71. The control unit 4 includes a controller 41, a battery 42 (shown in FIG. 3), an operating member 位于 located outside the board unit 2 and held by the user, and the 8 200831353 operating unit 45 communicates with the wireless Bluetooth. The controller 41 is controlled by the agreement. Thereby, the electric surfboard can be operated and used even in a state where the windsurfing 72 is not driven by the wind, and the leisure effect can be achieved. Referring to FIG. 8 and FIG. 9, a fifth preferred embodiment of the electric surfboard of the present invention is substantially the same as the first preferred embodiment, except that the electric surfboard further includes a balancing unit 8, and the balancing unit 8 includes Two fins 81 extending in the longitudinal direction and disposed on the bottom surface of the plate body 21. The plate unit 2 further includes a shroud 24 covering the motor 311. The shroud 24 is located in the flow channel 211. The plate body 21 further has a plurality of strips formed on the bottom surface and communicating with the controller 41 (eg Figure 3) and the underwater cooling channel 215.
