As a preferred solution: In this embodiment, the water inlet pipeline includes a flow meter 14, a water pump 15, a heating plate 16, a first solenoid valve 17 and a second solenoid valve 18 which are sequentially connected and arranged in the body 1, and the first solenoid valve 17 is connected to the first water outlet 110, and the second solenoid valve 18 is connected to the steam outlet 130. The water in the water tank 3 flows into the water pump 15 through the flow meter 14, and flows into the heating plate 16 for heating. The hot water heated by the heating plate 16 flows out from the first water outlet 110 to the coffee funnel 2 by the first solenoid valve 17, and the steam generated by the heating of the heating plate 16 is discharged from the steam outlet 130 into the steam milk frother 4 by the first solenoid valve 17 and the second solenoid valve 18.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 A water storage tray 111 is provided inside the first mounting groove 11, and a buffer tank 19 connected to the second solenoid valve 18 and the water storage tray 111 is provided inside the machine body 1. The function of the buffer tank 19 is to convert the excess high-temperature steam into low-temperature water after passing through the tortuous flow channel inside it, and then flow into the water storage tray 111, thereby greatly reducing the amount of steam flowing into the water storage tray 111, making the whole machine more superior in performance and longer in life. In addition, the water storage tray 111 can also be used to hold waste water or waste liquid when brewing coffee. When the water storage tray 111 is full, it can be removed from the machine body for cleaning, which is simple and convenient to operate.

[0033] Reference Figures 1 to 3 As a preferred solution: the machine body 1 has a first side wall, a second side wall and a third side wall which are vertically connected to each other, the first mounting groove 11 is arranged at the angle between the first side wall and the second side wall, the second mounting groove 12 is arranged at the 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, that is, the third mounting groove 13 is arranged on the second side wall. In this embodiment, the first side wall, the second side wall and the third side wall refer to the left side wall, the front side wall and the right side wall of the machine body 1 respectively. It can be seen that the utility model arranges the coffee funnel 2, the steam milk frother 4 and the water tank 3 on the machine body 1 in parallel, effectively utilizing the space outside the machine body 1, making the overall layout of the device more reasonable and compact. When disassembling, the water tank 3 can be pulled out obliquely from the angle between the front side wall and the right side wall, or can be pulled out horizontally directly from the front side wall or the right side wall, so the operation is more convenient and flexible, and can be applied to a variety of use environments. In order to facilitate the disassembly and assembly of the water tank, in this embodiment, recessed portions 35 are provided on both sides of the exterior of the water tank 3 , and a raised handle portion 36 is formed between the two recessed portions 35 .
