[0040] Embodiment one

[0041] Referring to Figures 1-7The portable coffee machine comprises a machine body 1, an extraction box 2 and a steam assembly 3, wherein the extraction box 2 and the steam assembly 3 are selectively detachably mounted on the machine body 1.

[0042] The machine body 1 comprises a mounting seat 11 for mounting the extraction box 2 or the steam assembly 3, which comprises a seat body 111 and a water outlet end 112 penetrating into the seat body 111, the water outlet end 112 being in fluid communication with a heating device or a water tank inside the machine body 1, so as to supply hot water or steam to the extraction box 2 or the steam assembly 3.

[0043] In the embodiment, the extraction box 2 and the steam assembly 3 are both connected to the mounting seat 11 in a rotary structure. The seat body 111 is a hollow cylinder with an open bottom, and a rotary buckle 113 is formed at the bottom of the inner circumferential wall of the seat body 111. The rotary buckle 113 is generally L-shaped, comprising a first buckle portion 1131 extending longitudinally and a second buckle portion 1132 extending transversely, the second buckle portion 1132 extending along the circumference of the inner circumferential wall of the seat body 111 in an arc shape, and the first buckle portion 1131 is located at one end of the second buckle portion 1132 in the transverse direction and extends upward from the end of the second buckle portion 1132. The upper surface of the second buckle portion 1132 is inclined, gradually inclining upward from the end away from the first buckle portion 1131 to the first buckle portion 1131, so as to serve as a guide for installation. The upper surface of the second buckle portion 1132 can be formed with a clamping groove 1133.

[0044] The steam assembly 3 comprises a first upper cover body 31, a diverter valve assembly, a steam rod 33 and a steam nozzle 34. The first upper cover body 31 is used for rotary connection with the rotary buckle 113 at the bottom of the seat body 111 of the mounting seat 11. The first upper cover body 31 is a hollow cylinder with an open bottom, such as a circular cylinder or a circular truncated cone. The top periphery of the first upper cover body 31 is formed with a clamping buckle 312, which can have one or at least two, such as four in the preferred embodiment, arranged at intervals along the circumference of the first upper cover body 31. When the steam assembly 3 is mounted, the clamping buckle 312 can be rotated clockwise (or counterclockwise) along the upper surface of the second buckle portion 1132 and clamped into the clamping groove 1133, thereby completing the installation of the mounting seat 11 and the steam assembly 3. A protrusion (not shown) can be formed on the lower surface of the clamping buckle 312, so that the protrusion is clamped into the clamping groove 1133 to achieve positioning.

[0045] A micro switch 12 for controlling the opening and closing of the whole machine can be arranged in the mounting seat 11. The top of the seat body 111 is provided with a cover plate 115. The micro switch 12 is arranged in the space surrounded by the seat body 111 and the cover plate 115. When the steam assembly 3 is installed, the buckle 312 on the first upper cover body 31 is installed in place and can abut against the contact of the micro switch 12 (indirect contact can be achieved through the cooperation of a slope structure, etc.), so that the key light on the machine body 1 is turned on, prompting the user that the machine is ready for use. At the same time, the water outlet end 112 can pass through the upper end 311 of the first upper cover body 31 and enter the upper cover 322 of the diverter valve assembly. When disassembling, the first upper cover body 31 is rotated in the opposite direction, and the micro switch is no longer triggered, and the key light is no longer turned on. The extraction box 2 comprises a second upper cover body 21 and a box body 22. The structure of the second upper cover body 21 is the same as that of the first upper cover body 31, so that one mounting seat 11 can be adapted for the installation of the extraction box 2 and the steam assembly 3. The water outlet end 112 can be in fluid communication with the box body 22.

[0046] The diverter valve assembly comprises a diverter valve 321, an upper cover 322, a lower cover 323 and a first sealing member 324. The upper cover 322 and the lower cover 323 can be buckled together and fixed to the upper end 311 of the first upper cover body 31 as a whole. The diverter valve 321 is partially arranged in the space formed by the upper cover 322 and the lower cover 323. The first sealing member 324 is in the form of a sealing ring and is arranged at the mounting position between the upper cover 322 and the lower cover 323 to prevent steam from leaking. The part of the diverter valve 321 cooperating with the upper cover 322 and the lower cover 323 can be in the form of a sphere. A second sealing member 313, such as a silica gel sealing ring, can be arranged at the connection between the upper cover 322 and the upper end 311 of the first upper cover body 31.

[0047] The steam rod 33 is connected to the bottom of the diverter valve 321 and can be fixed by threaded connection. The steam rod 33 is a bent rod, and the steam inlet 331 connected to the diverter valve 321 and the steam outlet 332 away from the diverter valve 321 are not on the same axis. A sheath 35 can be arranged on the outer periphery of the steam rod 33. The sheath 35 is made of heat-insulating material to facilitate the user to operate the steam rod 33 through the sheath 35. Since the part of the diverter valve 321 cooperating with the upper cover 322 and the lower cover 323 is in the form of a sphere, and the steam rod 33 is not a straight rod, the steam rod 33 can be rotated at any angle along the longitudinal axis (the connection and cooperation state of the diverter valve 321 and the water outlet end 112, the steam rod 33 remain unchanged) to cooperate with the container containing milk to perform the operation of frothing milk.

[0048] A third sealing member 333 can be arranged at the connection between the diverter valve 321 and the steam rod 33.

[0049] The steam nozzle 34 is connected at the steam outlet 332 of the steam rod 33, thereby the fluid communication between the water outlet end 112, the turning valve assembly, the steam rod 33 and the steam nozzle 34. The connection between the steam nozzle 34 and the steam rod 33 can be provided with a fourth sealing member 341. The steam nozzle 34 can have two optional structures, one is a single hole steam outlet, and the other is a two-hole or more steam outlet.

[0050] Embodiment two

[0051] Reference Figures 8-14 In the present embodiment, the difference from the above-mentioned embodiment one is that the installation mode of the steam assembly 3 and the extraction box 2 is magnetic attraction type.

[0052] The first upper cover body 31 is provided with a first magnet 37, and the top cover is provided with a magnet cover 371 to avoid the first magnet 37 from being separated from the first upper cover body 31. At this time, the second upper cover body 21 of the extraction box 2 is also provided with a first magnet. The seat body 111 of the mounting seat 11 is provided with a second magnet 114 to magnetically attract the first magnet 37.

[0053] When the steam assembly is installed, the first upper cover body 31 is transversely inserted into the bottom of the base 111 (the base 111 is no longer provided with a screw buckle) of the mounting seat 11, and is attracted by the second magnet 114 arranged in the base 111. When disassembling, the first upper cover body 31 can be operated in reverse.

[0054] The "fluid communication" referred to in the present application refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as first part and second part), i.e. the fluid (gas, liquid or mixture of the two) can flow or / and be transported from the first part to the second part along the flow path. It can be directly connected between the first part and the second part, or indirectly connected between the first part and the second part through at least one third party, which can be a fluid passage such as a pipeline, a channel, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing fluid flow or a combination thereof.
