[Prior Art] When the user operates the keyboard, it is inevitable that the liquid will splash out due to inadvertent eating and fall on the keyboard, which may cause a short circuit in the circuit part of the keyboard. If the keyboard is installed in an electronic device, the liquid flowing on the keyboard may flow into one of the motherboards of the electronic device, which often causes the motherboard to be short-circuited due to liquid and damage the motherboard, which will cause the entire electronic device. Damaged and caused significant damage. Therefore, there is a protection mechanism for the keyboard. The related art, such as the U.S. Patent Publication No. 4,948,281, discloses a keyboard waterproof protection mechanism, in which a plurality of keys (key) are protruded in a basic group, and a rubber lining is provided. A rubber gasket is disposed on a periphery of a top surface of the substrate, and a grid support is further disposed on the substrate, so that the rubber gasket is adhered to the periphery of the top surface of the substrate to form a receiving space. A liquid drain passes through the rubber gasket and the lattice support plate and passes through the accommodation space. When the liquid flows from the button to the accommodating space, the liquid can be discharged by the drain pipe. Another related art, such as the U.S. Patent Publication No. 6,398,436, discloses a waterproof protection mechanism for an electronic component having a keyboard, which is covered with a absorbing structure 5 200826130 (absorbent structure) on a circuit assembly. The absorbing structure is for absorbing liquid flowing through the keyboard to prevent liquid from flowing to the circuit board assembled on the electronic component. However, the absorption structure can absorb a relatively limited amount of liquid and can only absorb a small amount of liquid. If more liquid is accidentally poured into the keyboard, the barrier effect may not be fully achieved. SUMMARY OF THE INVENTION In view of the above problems, the problem to be solved by the present invention is to provide a keyboard having a drainage structure for smoothly discharging liquid flowing into a keyboard. Therefore, the present invention discloses a keyboard having a drainage structure, which is installed in an electronic device and guides a liquid discharge electronic device when a liquid flows in. The keyboard with the drainage structure comprises a keyboard button group, a waterproof film and a housing. The keyboard button set has a plurality of gaps, and the waterproof film is disposed on the bottom surface of the keyboard button group and has a notch and a discharge side. The waterproof film receives the liquid flowing through the gap and guides the liquid to the notch and the discharge side to flow out. The housing is provided with a keyboard button set and a waterproof membrane. The housing comprises a drainage groove, an inclined surface and a drainage opening. The upper edge of the drainage channel is connected to the discharge side to receive the liquid flowing out from the discharge side, and the bottom end of the drainage groove is a first end and a second end, respectively, and the first end is higher than the second end. The inclined surface is provided corresponding to the notch and one side of the inclined surface is connected to one side of the drainage groove to receive and guide the liquid flowing out of the notch to the drainage ditch. The drain port is disposed at the second end of the drain and communicates with the outside of the electronic device to guide the liquid of the drain to discharge the electronic device. Wherein the cross section of the gutter is a square groove, and the square groove is inclined toward one side of the waterproof membrane to guide the liquid to flow into the drainage ditch, and 6 200826130 increases the area of the cross section of the drainage ditch, In turn, the volume of the drainage ditch is increased as a whole. A peripheral portion of the waterproof film protrudes toward the keyboard button group with a protruding member, and the protruding member correspondingly contacts a portion of the periphery of the keyboard button group and forms a closed region with the drain groove. The peripheral edge of the waterproof film is correspondingly partially attached to the periphery of the bottom surface of the keyboard button group to form a closed area with the drainage ditch. In summary, the present invention utilizes a waterproof membrane to guide the liquid flowing through the keyboard button group into the drainage channel and then discharge the liquid through the arrangement of the drainage port. Therefore, the original keyboard design can be greatly changed without changing the original keyboard design. With drainage function. In this way, the electronic device on which the keyboard is mounted can be ensured, and the entire electronic device is damaged due to the infiltration of liquid from the keyboard.
