[0048] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0049] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0050] Except for the method of making milk foam as described in the above background technology, the making of milk foam is performed by a special machine or device. However, whether it is a coffee machine or a milk frother, when making milk foam, the milk foam is first made, then poured into the milk cup, and then the coffee machine or the milk frother is cleaned. As for the cleaning requirements, each time the milk foam is made, the corresponding milk foam making device needs to be cleaned, and the repeated cleaning work is a lot. In addition, many milk foam making equipments have very high requirements for the operation of the production personnel, and the level of operation may also determine the quality of the milk foam. It is understandable that if the milk foam is made directly in the milk cup or disposable milk cup, there is no need to clean the milk cup, and there is no need for the operator to make the milk foam, then the above-mentioned problems can be solved.

[0051] However, when solving the above-mentioned problems, the way to heat the milk is through heat conduction, that is, the contact between the milk beating device and the milk cup is used to provide the corresponding heat for the production of milk foam, so as to meet the conditions for the production of milk foam. At the same time, in order to make milk foam, the milk in the milk cup must be stirred to meet another condition for the production of milk foam. It is understandable that while improving the traditional milk beating method, two separate systems of heating and stirring need to be coordinated to complete the production of milk foam. This also results in the milk cup having to be made of a material with good thermal conductivity and the cooperation between the milk cup and the milk beating device requires the design of two separate systems of heating and stirring, resulting in design redundancy. In order to meet the requirements of heating and stirring the milk in the cup body of the milk cup while making milk foam, the present application is designed to achieve the above purpose by injecting steam into the milk cup.

[0052] Based on this, the first aspect of the present application provides a milk cup, comprising: a cup body 1 for loading milk, and a cup cover 2 is provided at the edge of the cup body 1 for sealing the cup body 1. Different from the related art, in the related art, milk or other beverages are introduced into the cup, and then heated and stirred accordingly to finally make milk foam. The present application uses a special cup body 1 to load milk to make milk foam, and the cup body 1 is sealed by the cup cover 2. It can be understood that the milk cup of the embodiment of the present application can be a disposable milk cup that is more convenient to use, and it can also be a non-disposable milk cup. The cup cover 2 can be a simple sealing film, or a lid that is adapted to the cup body 1 to seal the cup body 1, and there is no limitation here.

[0053] It should be noted that the milk cup of the present application can be loaded with milk, and can also be loaded with other drinks that need to be heated and stirred to change the taste. The present application is mainly aimed at making milk foam, so the following mainly introduces milk as an example.

[0054] At least one of the cup body 1 or the cup cover 2 may further include: a steam injection structure, used to inject steam into the cup body 1 to heat the milk and produce milk foam; steam is injected into the cup body 1 through the steam injection structure, and the temperature of the steam exchanges heat with the milk in the cup body 1 to achieve heating of the milk, and at the same time, the airflow brought by the pressurized steam stirs the milk in the cup body 1, thereby achieving simultaneous heating and stirring to achieve the production of milk foam for the milk in the cup body 1.

[0055] It is understandable that, in the production of milk froth, sufficient temperature and stirring are necessary conditions for milk to produce milk froth. In some embodiments, a certain proportion of air can be mixed in the injected steam to enhance the effect of milk froth formation.

[0056] In some embodiments, at least one of the cup body 1 or the cup cover 2 may further include: an exhaust structure for exhausting the gas in the cup body 1. As mentioned above, steam can be injected into the milk cup through the steam injection structure to produce milk foam in the milk in the cup body 1. During the steam injection process, the pressure in the cup body 1 will become larger and larger, so it is necessary to release the internal pressure of the cup body 1. When the gas is discharged through the exhaust structure to relieve the pressure, it is necessary to ensure that the exhaust structure does not discharge the milk in the cup body 1 or the produced milk foam. The exhaust structure may be just a part of the milk cup connected to the interior, and the exhaust structure can be pierced by a puncture device to produce an exhaust hole, thereby achieving exhaust.

[0057] It is understandable that the steam injection structure can be provided on the cup body 1 or on the cup cover 2 . Similarly, the exhaust structure corresponding to the steam injection structure can also be provided on the cup body 1 or on the cup cover 2 .

[0058] In some embodiments, the exhaust structure can be set at the center of the cup cover 2. It can be understood that when the injected steam heats and stirs the milk in the cup body 1, the milk in the cup body 1 will be closer to the side wall of the cup body 1 due to the centrifugal force. The exhaust port is set at the center of the cup cover 2. While it plays the role of exhaust and pressure relief, the milk in the cup body 1 or the generated milk foam is not easy to overflow from the exhaust port.

[0059] In some embodiments, the steam injection structure includes a steam injection channel 31 and an elastic sealing member 32. The steam injection channel 31 is used to inject steam into the cup body 1. In the embodiment of the present application, steam is injected into the cup body 1 by puncturing. After puncturing, that is, after steam is injected into the cup body 1 to produce milk foam in the milk in the cup body 1, the punctured object needs to be withdrawn from the cup body 1. The milk foam also contains water. If the puncture gap is too large, the milk foam in the cup body 1 will overflow from the puncture gap, causing contamination on the surface of the cup body 1. At the same time, the amount of milk foam produced will continue to overflow and cannot meet the amount of coffee production. Based on this, when the milk in the milk cup is not foamed, the elastic sealing member 32 is used to seal the steam injection channel 31. When the milk in the milk cup is in the process of making milk foam, the elastic sealing member 32 is connected to the steam injection channel 31 in the puncture state. After the milk foam is made, the elastic sealing member 32 uses its own elasticity to compress the gap caused by the puncture, thereby preventing leakage.

[0060] For further reference, Fig.11 As shown, in some embodiments, the elastic sealing member 32 includes a connecting channel 311, which is connected to the steam injection channel 31 through the steam outlet end of the connecting channel 311, and at least one of the steam inlet end and the steam outlet end of the connecting channel 311 is provided with a raised annular scraping wall 312, and the inner diameter of the annular scraping wall 312 is smaller than the inner diameter of the connecting channel 311. It can be understood that when steam is injected into the cup body 1 by puncturing, the parts performing the puncturing operation will definitely be stained with milk or other drinks in the milk cup, and similarly, when the milk foam is made, it will also be stained with milk foam. By providing a raised annular scraping wall 312 at at least one of the steam inlet end and the steam outlet end of the connecting channel 311, the puncturing parts can be scraped when the puncturing operation and the steam injection operation are completed, and further, the puncturing parts can be kept clean.

[0061] It can be understood that the raised annular scraper wall 312 can also scrape the puncture component before the puncture component punctures the seal. The seal and the raised annular scraper wall 312 can be made of food-grade silicone. Of course, there is no limitation on the manufacturing material. Other materials that meet the food-grade requirements while satisfying the above-mentioned sealing function can also be used as a replacement.

[0062] For further reference, Figure 4 As shown, the steam injection structure is arranged at the bottom of the cup body 1, the exhaust structure is arranged at the cup cover 2, and the steam injection channel 31 forms a first angle with the plane where the bottom of the cup body 1 is located. It can be understood that the injected steam uses the air pressure brought by the steam to stir the milk in the cup body 1. If the steam injection channel 31 forms an angle with the bottom of the cup body 1, the steam emission angle at the steam outlet end of the steam injection channel 31 can be directly used to stir the milk in the cup body 1. Similarly, the temperature in the steam can exchange heat with the milk in the cup body 1 to heat the milk, thereby producing a stable quality milk foam with a dense taste. The exhaust structure is arranged at the cup cover 2, and the height of the cup cover 2 is higher than the liquid level of the milk in the cup body 1 to avoid the milk being discharged through the exhaust structure.

[0063] Furthermore, the steam injection structure is arranged at a position close to the side wall of the cup body 1, and the first angle is 15° to 75°. The steam injection structure is arranged at a position close to the side wall of the cup body 1 at the bottom of the cup body 1. It can be understood that if the milk in the cup body 1 is to be stirred by the steam pressure, the farther the steam injection channel 31 of the steam injection structure is from the center of the bottom of the cup body 1, the easier it is to stir the milk in the cup body 1, so that the milk in the cup body 1 is stirred in a certain direction.

[0064] In some embodiments, reference Figure 6 The steam injection structure also includes an air guide sheet. When the steam injection structure is arranged at the bottom of the cup body 1 close to the side wall of the cup body 1, the first angle can also be 90°, of course, it can also be any angle. The air guide sheet is used to guide the flow direction of the injected steam, so that the steam after the guidance stirs the milk in the cup body 1. The best stirring effect is that the milk in the cup body 1 can be stirred clockwise or counterclockwise along the side wall of the cup body 1, and the function of the air guide sheet is to control the emission direction of the steam so that the milk in the cup body 1 can be stirred clockwise or counterclockwise.

[0065] In some embodiments, reference Figure 1 , Figure 2 , Figure 3The steam injection structure includes a hollow steam injection body 51, in which a steam injection channel 31 is formed. The steam injection channel 31 also includes a guide pipe 52 connected to the steam injection body 51, and the guide pipe 52 is connected to the steam outlet end of the steam injection channel 31. One end of the guide pipe 52 away from the steam injection channel 31 extends toward the side wall of the cup body 1, and the steam outlet direction of the guide pipe 52 is parallel to the tangent direction of the side wall of the cup body 1. The steam injected into the steam injection channel 31 is guided through the guide tube 52, and the steam outlet end of the steam injection channel 31 is parallel to the tangential direction of the side wall of the cup body 1, so that the emission direction of the steam in the guide tube 52 is parallel to the tangential direction of the side wall of the cup body 1, and the steam stirs the milk in the cup body 1 along the emission direction, so that the milk in the cup body 1 is stirred along the side wall of the cup body 1. The direction of the guide tube 52 is not limited here, and the direction of the guide tube 52 can be along the clockwise direction of the cup body 1, or along the counterclockwise direction of the cup body 1, so that the milk in the cup body 1 is stirred clockwise or counterclockwise along the cup body 1, and the stirring efficiency is higher.

[0066] Further, the steam injection body 51 is rotatably connected to the bottom of the cup body 1, the exhaust structure is arranged at the cup cover 2, and stirring teeth 53 are evenly arranged around the top of the steam injection body 51. The steam injection body 51 is rotatably connected to the bottom of the cup body 1, and the steam injected into the cup body 1 has a certain pressure. Due to the reaction force brought by the steam injection, the steam injection body 51 will drive the steam injection channel 31 connected thereto to rotate accordingly. When the steam injection body 51 rotates accordingly due to the reaction force, stirring teeth 53 are evenly arranged around the top of the steam injection body 51. The stirring teeth 53 can further realize the milk in the cup body 1, so that the milk foam is formed more efficiently. It can be understood that, here, the steam injection body 51 can be equivalent to the role of a circular rotor, the steam injection channel 31 is arranged inside the rotor, and the stirring teeth 53 are evenly arranged around the rotor. Of course, the shape of the steam injection body 51 can also be presented in other forms, as long as it can achieve the stirring of the milk in the cup body 1, which is not limited here.

[0067] It should be noted that, when the steam injection body 51 is only connected to the flow guide tube 52 and the stirring teeth 53 are not provided, the steam injection body 51 can be rotatably connected to the bottom of the cup body 1, or can be fixedly connected to the bottom of the cup body 1. When the steam injection body 51 is connected to the flow guide tube 52 and the stirring teeth 53 are provided, when synchronous stirring is required, it is preferred that the steam injection body 51 is rotatably connected to the bottom of the cup body 1, so as to achieve the purpose of stirring the milk in the cup body 1 by the coordinated rotation of the steam injection body 51 and the stirring teeth 53.

[0068] In some embodiments, the flow guide tube 52 is a venturi tube. It can be understood from the above description that the steam injected into the cup body 1 needs to have a certain air pressure, so as to achieve heat exchange with the milk in the cup body 1 to heat the milk, and to achieve rotational stirring of the milk in the cup body 1. By setting the flow guide tube 52 in the form of a venturi tube, the steam injected into the cup body 1 passes through the venturi tube, and the flow rate and air pressure of the steam emitted from the venturi tube are greater than the flow rate and air pressure of the incident steam. The greater air pressure stirs the milk in the milk cup, increasing the stirring efficiency. At the same time, the greater air pressure is also more conducive to heat exchange between the injected steam and the milk in the milk cup, thereby accelerating the heating efficiency of the milk.

[0069] In some embodiments, reference Figure 7 , Figure 8 , Fig. 9 As shown, the bottom center of the cup body 1 is rotatably connected with a rotor 61, and stirring teeth 53 are evenly arranged around the rotor 61. A guide blade 62 is arranged on one side of the rotor 61 close to the bottom of the cup body 1, and the steam outlet end of the steam injection channel 31 faces the guide blade 62. It can be understood that in this embodiment, the heating of the milk is mainly achieved by injecting steam into the cup body 1 to exchange heat with the milk in the cup body 1. At the same time, the pressure brought by the steam injected into the cup body 1 is used to drive the rotor 61 to rotate, and the milk is stirred by the rotation of the rotor 61. The steam outlet end of the steam injection channel 31 faces the guide blade 62, and the air pressure brought by the steam emitted from the steam injection channel 31 is guided by the guide blade 62. At the same time, the guide blade 62 drives the rotor 61 to rotate due to the reaction force brought by the air pressure of the steam. It can be understood that the steam injection channel 31 can select the angle of the first angle between the steam injection channel 31 and the bottom of the cup body 1 according to the setting of the guide blade 62. Further, the first angle can be 90°.

[0070] In some embodiments, reference Figure 5As shown, the steam injection structure is arranged on the side wall of the cup body 1, the exhaust structure is arranged at the cup cover 2, and the steam injection channel 31 of the steam injection structure forms a second angle with the side wall of the cup body 1. In the above embodiment, the steam injection structure is mainly arranged at the bottom of the cup body 1 to achieve heating and stirring of the milk in the cup body 1, so as to make milk foam. The inventor of the present application has found through experiments that the corresponding steam is injected through the side wall of the cup body 1, and the efficiency of making milk foam does not decrease. Moreover, if the steam is injected through the side wall of the cup body 1, it can even save the production of the guide tube 52 and the rotor 61. The steam injection channel 31 of the steam injection structure forms a second angle with the side wall of the cup body 1. The second angle can be specifically determined according to the size of the cup body 1, and is not specifically limited here. The steam injected through the steam injection channel 31 along the stirring direction of the milk in the cup body 1 directly drives the milk in the cup body 1 to stir. The same as the steam injected at the bottom of the cup body 1 is that the heating of the milk in the cup body 1 is achieved by heat exchange between the steam and the milk in the cup body 1.

[0071] In the above embodiments, reference Fig.10 As shown, the method of injecting steam from the bottom of the cup body 1 and discharging the gas in the cup body 1 from the cup cover 2, as well as injecting steam from the side wall of the cup body 1 and discharging the gas in the cup body 1 from the cup cover 2 are respectively introduced. The inventor of the present application thinks that in the above scheme, the depth of the steam injected into the cup body 1 in the milk cannot be adjusted. Then the inventor thinks that if the steam injection structure and the exhaust structure are both arranged at the cup cover 2, the device for injecting steam into the milk cup can be adjusted relative to the liquid level of the milk, and the direction of the steam injection can be adjusted, which is more conducive to the production of milk foam. Based on this, the inventor conducted a milk foam production test on the milk in the milk cup. Through the test, it was found that after the milk foam was formed in the milk cup, the distance between the liquid level of the milk foam and the cup cover 2 was sufficient, that is, even if the steam injection structure and the exhaust structure of the cup cover 2 are the same, and there is no elastic sealing member 32, the milk foam will not overflow. In other words, in the embodiments of the present application, the steam injection structure may be the same as the exhaust structure except that it is a certain part of the milk cup that is connected to the inside of the cover. After the puncture device completes the puncture at the certain part, the puncture device continues to inject steam into the cup body, and the injection position relative to the liquid level of the milk can be adjusted during the process of making milk froth, which is more conducive to making milk froth. Based on this, in the above embodiments, there is a scheme of injecting steam from the bottom of the milk cup and exhausting the air at the cup cover 2, so that steam is injected at the cup cover 2 of the milk cup and steam continues to be exhausted from the cup cover 2, that is, a "steam injection from above, exhaust from above" scheme. The steam injection structure is arranged at the edge of the cup cover 2, and the exhaust structure is arranged at the center of the cup cover 2.

[0072] In some embodiments, the above-mentioned "upper steam injection and upper exhaust" scheme is carried out. The inventor of the present application thinks that the milk cup can also be inverted, that is, the bottom of the milk cup faces upward, and the steam injection structure is also arranged at the bottom of the cup body 1. Then the exhaust structure also encounters the above-mentioned problem and cannot be arranged on the side wall of the cup body 1 or the cup cover 2. However, if the exhaust structure is arranged at the bottom of the cup body 1, it is possible that after the milk foam is made, the milk cup is placed normally, resulting in the milk foam or the water contained in the milk foam overflowing from the position where the exhaust structure is located. In order to solve this problem, if the exhaust structure is also the same as the steam injection structure, when it is needed When exhausting, the exhaust structure is punctured to exhaust. After the exhaust is completed, the corresponding puncture is pulled out, and the exhaust structure can also be closed. The design of the milk cup is mainly designed for simplification. When closing, the elasticity of the exhaust structure can also be used. After the exhaust is completed, the exhaust structure is closed to achieve the above purpose. Based on this, in some embodiments, the steam injection structure and the exhaust structure are both arranged at the bottom of the cup body 1, and the bottom surface of the cup body 1 is provided with an elastic sealing film, wherein the elastic sealing film can be arranged on the inner surface of the cup body 1 or on the outer surface of the cup body 1, and the elastic sealing film can be silicone that meets food grade. At the same time, when opening the exhaust structure, the device for opening the exhaust structure needs to be pushed out of the exhaust structure after the exhaust is completed to avoid the closing of the exhaust structure. For example, the exhaust structure is punctured with a puncture needle to form an exhaust hole in the exhaust structure, and the puncture needle needs to be withdrawn from the exhaust structure after the exhaust is completed.

[0073] It should be noted that in the above-mentioned scheme of realizing the above-mentioned “upper steam injection and upper exhaust” by inverting the cup body 1 of the milk cup, since the milk in the cup body 1 has a corresponding liquid level, it also has a corresponding liquid level after inversion. After the milk cup is inverted, the exhaust structure does not contact the liquid level. At the same time, after the milk cup is inverted, at least the steam outlet end of the steam injection channel 31 or the steam outlet end of the guide tube 52 in the steam injection structure is in contact with the liquid level and extends below the liquid level. In other words, at least the steam outlet end of the steam injection channel 31 or the steam outlet end of the guide tube 52 is to be immersed in the milk, then correspondingly, the steam injection body 51 or the rotor 61 will also be immersed in the milk, thereby realizing the heating and stirring of the milk in the cup body 1 and realizing the production of milk foam.

[0074] The second aspect of this application, reference Fig.12 As shown, a milk frothing device is provided, comprising: a steam injection device 8, wherein the steam injection device 8 is configured to inject steam into the steam injection structure of the milk cup of the first aspect, and steam is injected into the milk cup by the steam injection device 8 of the milk frothing device to achieve milk frothing on the milk in the milk cup.

[0075] The gas guide device 9 is configured to open the exhaust structure of the milk cup described in the first aspect to exhaust the gas in the cup body 1. Similarly, when the steam injection device 8 of the milk frothing device injects steam into the milk cup, the gas guide structure is required to open the exhaust structure to exhaust gas so as to balance the pressure inside the cup body 1.

[0076] In some embodiments, a cup holder 10 is further included. The cup holder 10 is used to accommodate the cup body 1. The steam injection device 8 and the gas guide device 9 are arranged on the cup holder 10. It can be understood that after the milk cup is placed in the cup holder 10, the cup holder 10 also plays a role in fixing the cup body 1 of the milk cup. The steam injection device 8 is arranged on the cup holder 10. While fixing the milk cup, the steam injection device 8 is used to inject steam into the milk cup.

[0077] Furthermore, the steam injection device 8 includes a first puncture needle 81, which is a hollow structure, and the first puncture needle 81 punctures the steam injection structure. Specifically, the elastic seal 32 can be punctured to connect to the steam injection channel 31, and the first puncture needle 81 with a hollow structure is used to inject steam into the steam injection channel 31. At the same time, the gas guide device 9 includes a second puncture needle 91, and the second puncture needle 91 is used to puncture the exhaust structure of the milk cup. It can be understood from the above that the exhaust structure can be set at the cup cover 2 of the milk cup, and can also be set at the bottom of the milk cup. If the exhaust structure is set at the cup cover 2 of the milk cup, that is to say, the first puncture needle 81 can be set at the bottom or side wall of the cup seat 10 to achieve puncture of the steam injection structure, and the second puncture needle 91 leaves an exhaust hole at the cup cover 2 after piercing the cup cover 2 at the top of the milk cup. , then the second puncture needle 91 can exit the puncture state, ensure the cleaning of the second puncture needle 91, and use the exhaust hole to discharge the gas in the milk cup. If the exhaust structure is set at the bottom of the milk cup, that is, the milk cup needs to be inverted to make milk foam, the first puncture needle 81 and the second puncture needle 91 pierce the bottom of the milk cup at the same time. Here, the second puncture needle 91 is also a hollow structure, that is, the inside of the second puncture needle 91 can lead out gas. After the second puncture needle 91 punctures the bottom of the cup body 1, it does not exit, but uses the hollow structure inside the second puncture needle 91 to lead out gas until the milk foam is made, and then exits the first puncture needle 81 and the second puncture needle 91. In other words, the structure of the second puncture needle 91 is determined according to the setting position of the steam injection structure of the milk cup, and can be a hollow structure or a non-hollow structure.

[0078] In some embodiments, the first puncture needle 81 and the second puncture needle 91 are retractable. The retractable arrangement of the first puncture needle 81 and the second puncture needle 91 enables the first puncture needle 81 to puncture the steam injection structure and the second puncture needle 91 to puncture the exhaust structure. Further, the position of the first puncture needle 81 is adapted to the position of the steam injection structure; and or the puncture angle of the first puncture needle 81 is adapted to the first angle and / or the second angle of the steam inlet channel of the steam injection structure. By the retractable arrangement of the first puncture needle 81, while the position of the first puncture needle 81 is adapted to the position of the steam injection structure, it can be arranged at the bottom of the cup holder 10 or the side wall of the cup holder 10 or the top of the cup holder 10, and then the puncture angle of the first puncture needle 81 is set according to the first angle and / or the second angle of the steam injection channel 31 of the steam injection structure, so that the first puncture needle 81 is adapted to the steam injection channel 31. In other words, the first angle and / or the second angle of the steam injection channel 31 of the steam injection structure are set according to the puncture angle of the first puncture needle 81. After puncture, the first puncture needle 81 enters the steam injection channel 31.

[0079] In some embodiments, reference Fig.13 As shown, the first puncture needle 81 can be rotatably arranged, and the side wall of the first puncture needle 81 is provided with a guide hole 82, and the opening direction of the guide hole 82 is inclined from the side wall of the first puncture needle 81 to the end of the first puncture needle 81 puncturing one end, which is used to guide the steam injected into the milk cup and form a cyclone. Through the introduction of the above embodiment, when the steam injected into the milk cup is guided, it is achieved through the structure in the milk cup. When the above-mentioned upper steam intake and upper exhaust scheme is carried out, due to the material limitation of the cup cover 2, the cup cover 2 may be a material covered with aluminum film, and the corresponding structure cannot be set at the cup cover 2. The guide hole 82 can be set through the side wall of the first puncture needle 81. The first puncture needle 81 punctures from the cup cover 2, and the steam will not be emitted through the end of the first puncture needle 81, but through the guide hole 82 on the side wall to achieve the diversion of the injected steam, and the milk is stirred through the opening direction of the guide hole 82.

[0080] Specifically, refer to Fig.12 and Fig.13As shown, after the milk cup is placed in the cup holder 10, if it is the above-mentioned lower steam intake and upper exhaust, the first puncture needle 81 and the second puncture needle 91 can be used to puncture the steam injection structure at the bottom of the cup body 1 for steam injection and the exhaust structure of the cup cover 2 for exhaust. If it is the above-mentioned upper steam injection and upper exhaust, the first puncture needle 81 and the second puncture needle 91 can be used to puncture the corresponding positions of the steam injection structure and the exhaust structure at the cup cover 2 respectively. Through the retractable setting of the first puncture needle 81, the first puncture needle 81 can be adjusted to inject steam at different liquid levels of the milk. Through the rotatable setting of the first puncture needle 81, the position of the steam relative to the milk level can be adjusted. Through the rotatable setting, in conjunction with the guide hole on the side wall, the direction of stirring the milk can be adjusted.

[0081] It should be noted that in the "upper steam injection, upper exhaust" scheme, Fig.13 The puncture direction of the first puncture needle 81 shown in the figure is perpendicular to the plane where the cup cover 2 is located. The puncture direction of the first puncture needle 81 may not be perpendicular to the plane where the cup cover 2 is located, and the specific angle is not specifically limited here.

[0082] In some embodiments, the pressure of the steam injected into the steam injection structure by the steam injection device 8 is configured to be 1-5 bar, and the milk in the milk cup can be heated and stirred by injecting steam with sufficient pressure.

[0083] In some embodiments, the temperature of the milk after the steam is injected into the steam injection structure by the steam injection device 8 is configured to be 60° to 65°. Similarly, the milk cup and milk frothing device of the present application can be stirred and heated for processing according to different beverage needs. The embodiment of the present application is mainly for stirring and heating milk to make milk foam. After the inventor of the present application conducted a study on the milk foaming at different temperatures, it was found that milk is more likely to form high-quality and stable milk foam at 60° to 65° Celsius. The milk foam formed at this temperature is dense in quality, and after adding coffee, it can enrich the mellow taste of coffee. Therefore, the temperature of the steam injected into the steam injection structure by the steam injection device 8 is configured to be 60° to 65°, and the heat exchange between the steam and the milk in the cup body 1 can form stable quality and dense milk foam in the cup body 1 at the current temperature.
