The water in the water tank 3 flows into the water pump 15 through the flow meter 14, and then flows into the heating disc 16 for heating. The hot water heated by the heating disc 16 flows out from the first water outlet 110 to the coffee funnel 2 through the first electromagnetic valve 17, and the steam generated by the heating disc 16 is discharged into the steam milk frother 4 through the first electromagnetic valve 17 and the second electromagnetic valve 18.

[0032] Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 6, the first mounting groove 11 is internally provided with a water storage disc 111, and the machine body 1 is internally provided with a buffer groove 19 which is communicated with the second electromagnetic valve 18 and the water storage disc 111. The buffer groove 19 functions to convert the excess high-temperature steam into low-temperature water after the excess high-temperature steam passes through the tortuous flow channel in the buffer groove 19, and then the low-temperature water flows into the water storage disc 111, thereby greatly reducing the amount of steam flowing into the water storage disc 111, and making the overall machine performance more superior and the service life longer. In addition, the water storage disc 111 can also be used to hold the waste water or waste liquid when brewing coffee. When the water storage disc 111 is full, it can be detached from the machine body for cleaning, which is simple and convenient to operate.

[0033] Referring to FIG. 1 to FIG. 3, as a preferred scheme: the machine body 1 has a first side wall, a second side wall and a third side wall which are connected perpendicularly to each other, the first mounting groove 11 is arranged at the included angle between the first side wall and the second side wall, the second mounting groove 12 is arranged at the included angle between the second side wall and the third side wall, and the third mounting groove 13 is arranged between the first mounting groove 11 and the second mounting groove 12, i.e. the third mounting groove 13 is arranged on the second side wall. In the embodiment, the first side wall, the second side wall and the third side wall respectively refer to the left side wall, the front side wall and the right side wall of the machine body 1, and thus it can be seen that the coffee funnel 2, the steam milk frother 4 and the water tank 3 are arranged side by side on the machine body 1, and the space on the outer side of the machine body 1 is effectively utilized, so that the overall layout of the equipment is more reasonable and compact. When disassembling, the water tank 3 can be pulled out obliquely from the included angle between the front side wall and the right side wall, or can be pulled out horizontally from the front side wall or the right side wall, and thus the operation is more convenient and flexible, and can be suitable for various use environments. In order to facilitate the disassembly and assembly of the water tank, the embodiment is externally provided with two accommodation recesses 35 on both sides of the water tank 3, and a protruding handle portion 36 is formed between the two accommodation recesses 35.
