DETAILED DESCRIPTION

[0026] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

In relation to the orientation description, such as the orientation or position relationship indicated by the upper, lower, front, rear, left, right, etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application. In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the skilled person in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0028] In order to help understand the present application, specific embodiments of the present application will now be described by examples and with reference to the drawings, that is Figures 1 to 8

[0029] Please refer to Figures 1 to 4 , the present application provides a milk foam tube, which comprises an emulsifying tube 100, an outlet tube 200 and a housing 400.

[0030] One end of the emulsifying tube 100 has an inlet 110, and the other end can be closed or directly connected with the outlet tube 200, so that the steam, air and milk liquid are continuously mixed and emulsified in the emulsifying tube, and finally form uniform and delicate milk foam.

[0031] ​The liquid outlet pipe 200 is connected with the emulsification pipe 100, specifically, one end of the liquid outlet pipe 200 is connected with the emulsification pipe 100 to receive the emulsified milk foam, and the other end is provided with a liquid outlet 210 to output the milk foam. The liquid outlet pipe 200 is provided with the liquid outlet 210, which is in communication with the liquid inlet 110, and the inner wall of the liquid outlet pipe 200 is provided with a limiting block 300 for reducing the flow area of the liquid outlet pipe 200;

[0032] The shell 400 is sleeved on the liquid outlet pipe 200, which can effectively shield the internal structure of the liquid outlet pipe 200 and improve the overall aesthetics of the product. It should be understood that in other embodiments, the components on the liquid outlet pipe 200 can also be fixed after being sleeved.

[0033] The steam, milk liquid and air are mixed and enter the liquid inlet 110 of the emulsification pipe 100, and then enter the liquid outlet pipe 200 after being emulsified and foamed in the emulsification pipe 100. When the milk foam passes through the liquid outlet pipe 200, the limiting block 300 blocks the milk foam, forcing the milk foam to flow in a smaller flow area, so that the originally disordered milk foam liquid is gathered, and the gathered milk foam flow is more uniform, thereby reducing the deviation of the milk foam flowing out, and enabling the milk foam liquid to flow out stably and smoothly.

[0034] Therefore, by providing the limiting block 300 on the inner wall of the liquid outlet pipe 200, the milk foam flowing through the liquid outlet pipe 200 is blocked by the limiting block, thereby reducing the flow area of the liquid outlet pipe 200, so that the originally dispersed and disordered milk liquid is gathered and flows out, improving the stability of the milk liquid flowing out of the liquid outlet 210, and ensuring the production effect of the milk foam and the quality of the beverage. It can be understood that the milk foam pipe can not only be used for emulsifying and outputting milk foam, but also can be used for outputting milk liquid.

[0035] Considering that the limiting block 300 is directly fixed on the inner wall of the liquid outlet pipe 200, it is inconvenient to clean the inner side pipe of the limiting block 300 subsequently, therefore, the whole is referred to Figure 3 , and referred to Figure 5 In some more specific embodiments, the liquid outlet pipe 200 is provided with an opening 220 and a cover 230, the cover 230 cooperates with the opening 220, and the limiting block 300 is arranged on the cover 230, that is, the limiting block 300 is not integrally formed with the liquid outlet pipe 200. When the milk foam flows through the cover 230, the limiting block 300 on the cover 230 can block to reduce the flow area of the milk foam. When the inner pipe of the liquid outlet pipe 200 needs to be cleaned, the cover 230 can be directly removed. In addition, the size of the shell 400 and the size of the liquid outlet pipe 200 are matched, and the cover 230 can be fixed after being sleeved on the shell 400, so as to improve the sealing performance of the cover 230 after being installed, and prevent the cover 230 from falling off during foaming use due to poor installation.

[0036] In order to enhance the stability of the connection between the liquid outlet pipe 200 and the shell 400, in some embodiments, reference is made toFigure 3 The structure of the liquid outlet pipe 200 and the shell 400 is shown. The liquid outlet pipe 200 is provided with a groove 240, and the inner wall of the shell 400 is provided with a protrusion 410 corresponding to the groove 240. The groove 240 and the protrusion 410 cooperate. When installing, the inner wall of the shell 400 slides along the liquid outlet pipe 200, and then the protrusion 410 is clamped in the groove 240. During the operation of the milk foam pipe, the groove 240 and the protrusion 410 cooperate with each other to limit the relative movement of the liquid outlet pipe 200 and the shell 400, and avoid the shaking caused by the loose connection between the liquid outlet pipe 200 and the shell 400 affecting the flow effect of the milk foam liquid.

[0037] Further, referring to Figure 4 , the outer surface of the liquid outlet pipe 200 is provided with a plurality of guide strips 250 for guiding the sliding of the protrusion 410 along the circumferential direction thereof. When installing the shell 400, the protrusion 410 is aligned with the guide strips 250 and slides along the guide strips 250 until the protrusion 410 falls into the groove 240. Therefore, the guide strips 250 can guide the protrusion 410 to slide into the groove 240 accurately, reduce installation errors, and improve assembly efficiency.

[0038] Optionally, referring to Figure 2 , the number of the plurality of guide strips 250 is four, and the four guide strips 250 are uniformly distributed along the circumferential direction of the liquid outlet pipe 200. When installing, the inner wall of the shell 400 slides along the guide strips 250, and finally the protrusion 410 of the shell 400 is in cooperation with the groove 240 after the inner wall of the shell 400 abuts against the four guide strips 250 to further prevent the inclination or shaking of the shell 400 after installation.

[0039] In addition, in some specific embodiments, the milk foam pipe further comprises an adjusting cap 500 connected with the closed end of the emulsification pipe 100. The position of the milk foam pipe can be rotated by holding the adjusting cap 500, and the angle of the liquid outlet 210 can be adjusted as needed.

[0040] In the embodiment of ensuring the accurate relative position of the shell 400 and the liquid outlet pipe 200 in the milk foam pipe, the end of the liquid outlet pipe 200 close to the emulsification pipe 100 is provided with a stop ring 260 for limiting the position of the shell 400. When the shell 400 slides to contact the stop ring 260, the stop ring 260 blocks the shell 400 from moving further in the direction of the emulsification pipe 100, thereby limiting the sliding position of the shell 400 on the liquid outlet pipe 200 and preventing the shell 400 from sliding excessively on the liquid outlet pipe 200.

[0041] To further optimize the flow state of the milk liquid in the liquid outlet pipe 200, in some arrangements of the liquid outlet pipe 200, the inner wall of the liquid outlet pipe 200 is provided with a flow guide strip 270 along the length direction thereof, and the flow guide strip 270 extends outwardly along the liquid outlet 210. The flow guide strip 270 can guide the milk liquid to flow more smoothly to the liquid outlet 210, reduce the stagnation of the milk liquid in the liquid outlet pipe 200, and further improve the stability and smoothness of the milk liquid flow.

[0042] The application also provides a milk froth assembly 600, Figure 6 A structural schematic diagram of a milk froth assembly 600 is shown, Figure 8 A structural schematic diagram of another milk froth assembly 600 is shown, which also includes a box 620, a four-way pipe 610, and the milk froth pipe according to any one of the above technical solutions. Specifically, the four-way pipe 610 has an air inlet channel 611, a steam channel 612, a milk inlet channel 613, and a mixing interface 614. The four-way pipe 610 is arranged in the box, and the box 620 contains milk liquid. The milk inlet channel 613 is in communication with the bottom of the box 620 to suck the milk liquid. The air inlet channel 611 is provided with an opening 220 to suck air. The air inlet channel 611, the steam channel 612, the milk inlet channel 613, and the mixing interface 614 are in communication. Various raw materials or gases enter the different channels of the four-way pipe 610. When steam is sprayed through the steam channel 612, a negative pressure is formed in the milk inlet pipe, so that the milk liquid and air under atmospheric pressure are sucked into the emulsification pipe 100. The milk liquid, steam, and air are mixed sufficiently, and the milk liquid is emulsified violently, and then frothed, and finally the stable milk froth is led out of the liquid outlet 210.

[0043] The application also provides a coffee machine including the milk froth assembly 600 as above. When the coffee machine is working, the milk froth assembly 600 is started, and the milk froth assembly 600 produces milk froth, which is then added to coffee. It can be understood that the frothing principle and related effects of the milk froth assembly 600 are as described above, and will not be described here. Therefore, by providing the milk froth assembly 600, the coffee machine can produce stable and high-quality milk froth, improve the quality of coffee drinks, and improve the quality of coffee drinks made by using the coffee machine.
