Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and more particularly to an external milk frother and coffee machine. Background Technology

[0002] With the popularization of coffee culture, fully automatic or semi-automatic coffee machines are increasingly becoming common equipment in homes and offices. As an important accessory of coffee machines, the milk frother's function is to prepare milk foam for espresso, such as lattes and cappuccinos, by mixing high-temperature steam, air, and milk.

[0003] Currently available external milk frothers, such as the one disclosed in the existing patent (publication number: CN220236647U), require a mixing chamber and an air intake channel connected to the outside environment to be set on the mounting base. An adjustment knob on the mounting base is then used to rotate, opening or closing the mixing chamber to control the air intake and de-airing process, thus controlling the milk foam generation. However, this method requires machining both the mixing chamber and the air intake channel on the mounting base simultaneously, resulting in a more complex overall structure, higher precision requirements, more cumbersome manufacturing processes, and increased manufacturing costs. Utility Model Content

[0004] In order to simplify the air intake structure of the external milk frother, facilitate the reduction of manufacturing costs and improve production efficiency, this utility model provides an external milk frother and a coffee machine.

[0005] This utility model is achieved by the following solution: An external milk frother includes a mounting base and an adjustment knob. The mounting base has a mixing chamber, and a connecting seat is provided on the outer periphery of the mounting base. The connecting seat has an air inlet for connecting the outside world and the mixing chamber. The adjustment knob is rotatably disposed in the connecting seat and can be rotated to a first position and a second position. The end of the adjustment knob has a sealing part, and the outer periphery of the adjustment knob has an air inlet groove that extends to the end of the adjustment knob. When the adjustment knob is rotated to the first position, the sealing part blocks the air inlet. When the adjustment knob is rotated to the second position, the air inlet groove connects the air inlet and the outside world. In the external milk frother described above, the sealing part is a sealing protrusion.

[0006] As described above, the external milk frother includes a rotating disk and a rotating sealing rod on the rotating disk. The rotating sealing rod is inserted into the connecting seat, and the sealing part and the air inlet groove are located on the rotating sealing rod.

[0007] As described above, the external milk frother has an air inlet groove comprising a narrow diameter section and a wide diameter section that are interconnected. The narrow diameter section is located on the outer periphery of the rotating sealing rod, and the wide diameter section spans the outer periphery and end of the rotating sealing rod.

[0008] As described above, the external milk frother has an annular positioning protrusion extending circumferentially on the outer periphery of the rotating sealing rod, and an annular positioning groove that is limited and matched with the annular positioning protrusion inside the connecting seat.

[0009] As described above, in the external milk frother, the connecting seat has a clearance notch at one end facing the adjustment knob. When the adjustment knob is rotated to the second position, the air inlet groove is exposed through the clearance notch.

[0010] As described above, the external milk frother has a protrusion on the rotating sealing rod that corresponds to the air inlet groove.

[0011] As described above, the external milk frother has anti-slip textures on the outer periphery of the rotating disc.

[0012] As described above, the external milk frother has a steam nozzle at the upper end of the mounting base that communicates with the mixing chamber, and a milk inlet connector on the outer periphery of the mounting base that communicates with the mixing chamber.

[0013] This application also discloses a coffee machine, including an external milk frother as described above.

[0014] Compared with the prior art, this application has the following advantages: This invention sets both the air inlet groove and the sealing part on the adjustment knob. By rotating the adjustment knob to the first position or the second position, the state of the sealing part blocking the air inlet hole or the air inlet groove connecting the air inlet hole can be switched. There is no need to set an additional air inlet channel on the mounting base, which effectively simplifies the air inlet structure of the external milk frother, and facilitates the reduction of manufacturing costs and the improvement of production efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Example: This example discloses a coffee machine, which includes as follows Figures 1 to 7The external milk frother shown includes a mounting base 1 and an adjustment knob 2. The mounting base 1 has a mixing chamber 11 inside, and a connecting seat 3 is provided on the outer periphery of the mounting base 1. The connecting seat 3 has an air inlet 31 for connecting the outside world and the mixing chamber 11. The adjustment knob 2 is rotatably disposed in the connecting seat 3 and can be rotated to a first position and a second position. The end of the adjustment knob 2 has a sealing part 4, and the outer periphery of the adjustment knob 2 has an air inlet groove 5 that can extend to the end of the adjustment knob 2. When the adjustment knob 2 is rotated to the first position, the sealing part 4 blocks the air inlet 31. When the adjustment knob 2 is rotated to the second position, the air inlet groove 5 connects the air inlet 31 and the outside world. In this embodiment, the upper end of the mounting base 1 is provided with a steam nozzle 6 communicating with the mixing chamber 11, and the outer periphery of the mounting base 1 is provided with a milk inlet connector 7 communicating with the mixing chamber 11. The steam nozzle 6 is used to deliver steam into the mixing chamber 11, and the milk inlet connector 7 is used to deliver milk into the mixing chamber 11. In this embodiment, by setting both the air inlet groove 5 and the sealing part 4 on the adjusting knob 2, the state of the sealing part 4 blocking the air inlet hole 31 or the air inlet groove 5 connecting to the air inlet hole 31 can be switched by rotating the adjusting knob 2 to the first position or the second position. There is no need to set an additional air inlet channel on the mounting base, which effectively simplifies the air inlet structure of the external milk frother, making it easier to reduce manufacturing costs and improve production efficiency. In this embodiment, when the adjusting knob 2 is rotated to the first position, that is, when the sealing part 4 blocks the air inlet hole 31, the milk is heated. When the adjusting knob 2 is rotated to the second position, that is, when the air inlet groove 5 connects the air inlet hole 31 to the outside, outside air can be easily introduced into the mixing chamber 11, which generates milk foam.

[0027] Furthermore, the sealing part 4 is a sealing protrusion. To facilitate the sealing part 4 sealing or disengaging from the air inlet 31, the outer surface of the sealing protrusion is spherical.

[0028] Furthermore, to facilitate user rotation of the adjustment knob 2, the adjustment knob 2 includes a rotating disk 21 and a rotating sealing rod 22 disposed on the rotating disk 21. The rotating sealing rod 22 is inserted into the connecting seat 3, and the sealing part 4 and the air inlet groove 5 are disposed on the rotating sealing rod 22. The sealing part 4 and the air inlet groove 5 are both integrated on the rotating sealing rod 22, which facilitates optimization of the overall structure of the mounting seat 1.

[0029] Furthermore, the air inlet groove 5 includes a narrow diameter section 51 and a wide diameter section 52 that are interconnected. The narrow diameter section 51 is located on the outer periphery of the rotary sealing rod 22, and the wide diameter section 52 spans the outer periphery and end of the rotary sealing rod 22. In this embodiment, by setting the narrow diameter section 51 to communicate with the outside, the amount of air entering the mixing chamber 11 can be effectively controlled, ensuring the effective generation of milk foam. At the same time, by connecting the wide diameter section 52 to the air inlet hole 31, it is ensured that the air entering the air inlet groove 5 can efficiently enter the air inlet hole 31.

[0030] Furthermore, in order to improve the rotational stability of the adjustment knob 2 on the mounting base 1, the outer peripheral side of the rotary sealing rod 22 is provided with an annular positioning protrusion 221 extending in the circumferential direction, and the connecting base 3 is provided with an annular positioning groove 32 that limits and cooperates with the annular positioning protrusion 221.

[0031] Furthermore, in order to enable the air intake groove 5 to effectively introduce external gas into the mixing chamber 11, the connecting seat 3 is provided with a clearance notch 33 at one end facing the adjustment knob 2. When the adjustment knob 2 is rotated to the second position, the air intake groove 5 is exposed through the clearance notch 33.

[0032] Furthermore, the rotary sealing rod 22 is provided with a protrusion 222 whose position corresponds to that of the air inlet groove 5. The protrusion 222 is located at one end of the rotary sealing rod 22 near the rotating disk 21, so that the user can clearly know the rotation position of the rotary sealing rod 22 by observing the position of the protrusion 222.

[0033] Furthermore, in order to improve the stability of the user rotating the adjustment knob 2, the outer periphery of the rotating disk 21 is provided with anti-slip texture 23.

[0034] The working principle of this embodiment is as follows: In this embodiment, both the air inlet groove 5 and the sealing part 4 are set on the adjustment knob 2. By rotating the adjustment knob 2 to the first position or the second position, the state switching between the sealing part 4 blocking the air inlet hole 31 and the air inlet groove 5 connecting the air inlet hole 31 can be realized. There is no need to set up an additional air inlet channel on the mounting base, which effectively simplifies the air inlet structure of the external milk frother, and facilitates the reduction of manufacturing costs and the improvement of production efficiency.

[0035] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
