Specifically, the machine body 1 is in a columnar shape. The machine body 1 is provided with a center boss 103 and a connecting boss 104 on the top surface. The center boss 103 is upwardly extended from the top surface of the machine shell and is located at the middle of the top surface of the machine body 1. The connecting boss 104 is upwardly extended from the top surface of the machine shell and is located at the front side of the center boss 103. The turnover water outlet 10 is annular and its front end is rotatably connected with the connecting boss 104 through a turnover structure. When the turnover water outlet 10 is unfolded, the turnover water outlet 10 is rotated forward relative to the connecting boss 104 and away from the top surface of the machine body 1 and is located at the front side of the center boss 103. At this time, the turnover water outlet 10 is turned away from the machine body 1. The water outlet 102 is directed downward of the machine body 1 to realize the working of the portable instant boiling water machine and provide hot water. When the turnover water outlet 10 is stored, the turnover water outlet 10 is rotated backward relative to the connecting boss 104 and abuts against the top surface of the machine body 1 and is arranged around the periphery of the center boss 103. The turnover water outlet 10 is turned toward the machine body 1. The water outlet 102 is directed upward of the machine body 1 to realize the storage of the portable instant boiling water machine. Therefore, the portable instant boiling water machine with the above technical scheme does not need to reserve a containing cavity or a containing opening on the machine body 1 to accommodate the turnover water outlet 10, can realize the unfolding or storage of the water outlet 102, makes the appearance structure of the machine body 1 simpler, reduces the design difficulty of the mold and the manufacturing cost, reduces the research and development cost of the enterprise, lowers the sales price of the product and improves the market competitiveness of the product.
