Description

Technical Field

[0001] This utility model relates to the field of beverage equipment technology, and in particular to an adjustable milk frother assembly, a beverage outlet assembly, and a beverage equipment. Background Technology

[0002] Milk-based drinks, such as milk coffee, require heating the milk or creating milk foam during the preparation process. Therefore, the preparation of the milk is particularly important. For milk coffee machines, the milk frother is usually installed on the coffee beverage outlet. It uses negative steam pressure to mix milk, air, and steam for heating to create a dense and delicious hot milk foam and hot milk. By adjusting the real-time milk intake at different settings, the temperature and foaming of the milk beverage can be regulated.

[0003] Currently, multi-level adjustable milk frothers require users to remove the frother, or even pull out the nozzle, each time they need to change the level. Then, they need to adjust the nozzle to the corresponding level, reinstall the nozzle, and then reinstall the frother. This results in a poor user experience and inconvenience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable milk frother assembly, a beverage outlet assembly, and a beverage equipment, solving the technical problem that when making hot milk and milk foam in milk beverage machines, the milk frother's settings are inconvenient to adjust, requiring the milk frother to be removed or even the nozzle to be pulled out for adjustment.

[0005] This utility model is achieved through the following technical solution:

[0006] An adjustable milk frother assembly includes:

[0007] The milk frother body has a first mixing chamber and a second mixing chamber that are interconnected inside the milk frother body. The first mixing chamber has an air inlet and a milk inlet, and the second mixing chamber has a steam inlet.

[0008] A steam nozzle, which is sealed and connected to the steam inlet;

[0009] An air connector, which is sealed and connected to the air inlet;

[0010] A milk tube connector is sealed and connected to the milk inlet. A milk supply channel is formed inside the milk tube connector. Multiple milk outlet holes with different cross-sectional sizes are distributed in the circumferential direction of the milk tube connector. The milk outlet holes are used to connect the milk supply channel with the first mixing chamber.

[0011] When it is necessary to adjust the milk flow rate of the milk frother, the user can manually adjust the insertion direction of the milk tube connector to control the corresponding milk outlet to communicate with the first mixing chamber.

[0012] Furthermore, the milk tube connector includes a milk outlet portion located at the end of the milk tube connector. The milk outlet portion has a polygonal structure, and milk outlet holes are formed on multiple sides of the milk outlet portion.

[0013] One of the plurality of sides is in clearance fit with the inner peripheral wall of the first mixing chamber; the other sides of the plurality of sides are in sealing contact with the inner peripheral wall of the first mixing chamber.

[0014] Furthermore, the milk tube connector also includes a body part connected to the milk outlet, and a sealing ring is formed on the outer peripheral surface of the body part, the sealing ring abutting against the inner peripheral wall of the first mixing chamber.

[0015] Furthermore, the outer peripheral surface of the main body is also formed with a mounting portion, which is located at the end of the sealing ring away from the milk outlet portion, and the mounting portion abuts against the inner peripheral wall of the first mixing chamber.

[0016] Furthermore, the first mixing chamber includes a first chamber, a second chamber, and a third chamber that are connected in sequence and have gradually increasing cross-sectional area. The milk outlet abuts against the first chamber, the sealing ring abuts against the inner peripheral wall of the second chamber, and the mounting part abuts against the inner peripheral wall of the third chamber.

[0017] Furthermore, the mounting part has a plurality of marking parts, and the plurality of marking parts correspond one-to-one with the plurality of milk outlet holes.

[0018] Furthermore, in the radial direction of the first mixing chamber, the milk outlet and the air inlet are misaligned, and in the axial direction of the first mixing chamber, the air inlet is located between the milk outlet and the second mixing chamber.

[0019] Furthermore, the milk tube connector is made of hard plastic, while the part of the milk frother that mates with the milk tube connector is made of soft rubber.

[0020] This application also provides a beverage outlet component, including a housing, a cap, and a coffee interface component, a hot water interface, and the aforementioned adjustable milk frother component integrated inside the housing. The cap is detachably connected to the housing to cover the adjustable milk frother component.

[0021] This application also provides a beverage device, including the beverage outlet component described above.

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] By incorporating the milk inlet hole for adjusting the milk flow rate into the milk tube connector, when adjusting the setting, the user only needs to manually adjust the insertion direction of the milk tube connector to connect the selected milk outlet hole (with the corresponding setting) to the first mixing chamber. There is no need to first remove the milk frothing interface component from the beverage outlet assembly of the coffee machine, and then remove the steam nozzle from the milk frothing interface component. The temperature and frothing degree of the milk can be adjusted without the need to remove the milk frothing interface component from the milk frothing interface component. The structure is simple, the operation is convenient, and the cost is low. Attached Figure Description

[0031] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-3As shown, an adjustable milk frother assembly according to an embodiment of the present invention includes a milk frother body 1, a steam nozzle 2, an air connector 3, and a milk tube connector 4. The milk frother body 1 has a first mixing chamber 10 and a second mixing chamber 11 that are interconnected. The first mixing chamber 10 has an air inlet 100 and a milk inlet 101, and the second mixing chamber 11 has a steam inlet 110. The steam nozzle 2 is sealed to the steam inlet 110, the air connector 3 is sealed to the air inlet 100, and the milk tube connector 4 is sealed to the milk inlet 101. A milk supply channel 40 is formed inside the milk tube connector 4, and multiple milk outlet holes 411 of different cross-sectional sizes are distributed circumferentially on the milk tube connector 4. The milk outlet holes 411 are used to connect the milk supply channel 40 and the first mixing chamber 10. When it is necessary to adjust the milk flow rate of the milk frother body 1, the user manually adjusts the insertion direction of the milk tube connector 4 to control the connection between the corresponding milk outlet hole 411 and the first mixing chamber 10.

[0033] During operation, steam enters the second mixing chamber 11 of the milk frother body 1 through the steam nozzle 2. Due to the narrow design of the middle section of the second mixing chamber 11, the steam flow velocity increases as it passes through the middle section, thus creating a negative pressure within the second mixing chamber 11. Under this negative pressure, milk enters the first mixing chamber 10 through the milk pipe connector 4, and air enters the first mixing chamber 10 through the air connector 3 and mixes with the milk in the first mixing chamber 10. Simultaneously, under the negative pressure created by the increased steam flow velocity, the milk and air mixture in the first mixing chamber 10 flows into the second mixing chamber 11 and mixes thoroughly with the steam, generating milk foam. By supplying a certain proportion of milk through the milk pipe connector 4 and a certain proportion of air through the air connector 3, the milk is heated and frothed within the chamber of the milk frother body 1, achieving a dense milk foam effect.

[0034] Preferably, the milk hose connector 4 has multiple settings, and each setting corresponds to a milk outlet 411 with a different cross-sectional size. If the user needs to adjust the real-time milk flow to achieve temperature and foaming control of the milk beverage, the user can select the corresponding setting by plugging and unplugging, thereby adjusting the amount of milk entering the first mixing chamber 10. By selecting different sized milk outlets 411, precise control of the milk flow rate can be achieved. This not only simplifies the operation process but also ensures that the user can quickly and accurately adjust the taste and temperature of the beverage to meet the needs of different customers. In addition, in this embodiment, when the user adjusts the setting of the milk hose connector 4, the milk flow rate can be adjusted without disassembling the milk frother body 1, thereby controlling the temperature and frothing degree of the milk. The structure is simple, easy to use, low in cost, and provides a good user experience. Furthermore, compared to existing methods that adjust the milk flow rate by adjusting the outlet after mixing milk and air, this application directly adjusts the milk volume before mixing milk and air, adjusting the amount of milk (excluding air) entering through the outlets 411 with different diameters, resulting in more precise milk flow control. Furthermore, the adjustable milk frother assembly of this application has good compatibility. The milk tube connector 4 can better adapt to existing milk frother products without adjustable settings. Multiple milk volume adjustments can be achieved simply by replacing the milk tube connector 4 without changing the milk frother structure.

[0035] In this embodiment, the milk tube connector 4 is made of hard plastic, while the part of the milk frother body 1 that mates with the milk tube connector 4 is made of soft rubber. Furthermore, the steam nozzle 2, air inlet pipe 3, and milk tube connector 4 are all detachably and sealed to the milk frother body 1, ensuring ease of maintenance and cleaning. In addition, the design of the milk outlet 411 on the milk tube connector 4 allows for better disassembly and cleaning, effectively preventing residual milk stains from easily breeding bacteria.

[0036] like Figure 3 and Figure 4 As shown, the milk tube connector 4 includes a milk outlet section 41 located at the end of the milk tube connector 4. The milk outlet section 41 has a polygonal structure, and milk outlet holes 411 are formed on multiple side surfaces 410 of the milk outlet section 41. One of the multiple side surfaces 410 is in clearance fit with the inner peripheral wall of the first mixing chamber 10. The other side surfaces 410 are in sealing contact with the inner peripheral wall of the first mixing chamber 10. In this embodiment, the milk outlet section 41 has a quadrilateral structure. When the milk outlet section 41 is connected to the milk frother body 1, one side surface 410 of the milk outlet section 41 is in clearance fit with the inner peripheral wall of the first mixing chamber 10, so that milk can flow out from the milk outlet hole 411 corresponding to that side surface into the first mixing chamber 10, while the other three side surfaces 410 are in sealing contact with the inner peripheral wall of the first mixing chamber 10 to block the corresponding milk outlet holes 411, so as to avoid affecting the milk output. Of course, the milk outlet 41 can also be other polygonal structures, such as triangular, pentagonal, hexagonal and other polygonal structures.

[0037] like Figure 3and Figure 4 As shown, the milk tube connector 4 also includes a body part 42 connected to the milk outlet part 41. A sealing ring 420 is formed on the outer peripheral surface of the body part 42. The sealing ring 420 abuts against the inner peripheral wall of the first mixing chamber 10 to prevent milk or air in the first mixing chamber 10 from overflowing from the milk inlet 101.

[0038] like Figure 3 and Figure 4 As shown, a mounting portion 421 is also formed on the outer peripheral surface of the main body portion 42. The mounting portion 421 is located at the end of the sealing ring 420 away from the milk outlet portion 41, and the mounting portion 421 abuts against the inner peripheral wall of the first mixing chamber 10.

[0039] like Figure 3 and Figure 4 As shown, the first mixing chamber 10 includes a first chamber 102, a second chamber 103, and a third chamber 104 that are connected in sequence and have gradually increasing cross-sectional areas. The milk outlet 41 abuts against the first chamber 102, the sealing ring 420 abuts against the inner peripheral wall of the second chamber 103, and the mounting part 421 abuts against the inner peripheral wall of the third chamber 104. This layered connection ensures a precise fit between the milk frother body 1 and the milk tube connector 4, preventing radial misalignment between the milk frother body 1 and the milk tube connector 4, which could lead to milk or air leakage.

[0040] like Figure 3 and Figure 4 As shown, the mounting part 421 has multiple marking parts 422, each corresponding to a different milk outlet 411. The marking parts 422 allow users to intuitively identify the current setting, improving operational efficiency. Each marking part 422 is equipped with a corresponding indicator mark, which can be a number, letter, or other indicative symbol. These marks enhance the clarity and readability of the marking parts 422, improving the user experience. In this embodiment, the marking parts 422 are labeled with Arabic numerals, and the correspondence between the marking parts 422 and the milk outlet 411 allows users to quickly and accurately find the desired setting during adjustment, making it easy for both novice and experienced users to operate.

[0041] like Figure 3 As shown, in the radial direction of the first mixing chamber 10, the milk outlet 411 and the air inlet 100 are misaligned, and in the axial direction of the first mixing chamber 10, the air inlet 100 is located between the milk outlet 411 and the second mixing chamber 11, so as to avoid the air entering from the air inlet 100 from obstructing the normal milk outlet of the milk outlet 411.

[0042] like Figure 5 and Figure 6As shown, this utility model also provides a beverage outlet component, including a housing 5, a cap 8, and a coffee interface component 6, a hot water interface 7, and an adjustable milk frother component integrated inside the housing 5. The cap 8 is detachably connected to the housing 5 to cover the adjustable milk frother component. In this embodiment, when it is necessary to adjust the milk flow rate, simply pull out the milk tube connector 4, select the corresponding setting, and reinsert it according to the direction of the gap between the side 410 of the milk outlet 411 corresponding to the selected setting and the inner peripheral wall of the first mixing chamber 10. The milk flow rate can be adjusted without disassembling the cap 8, making the operation simple and convenient.

[0043] like Figure 7 As shown, the coffee interface assembly 6 includes a flow divider 60 and an inlet 61, an overflow 62, and multiple outlets 63 integrally formed on the flow divider 60. A buffer chamber is formed within the flow divider 60, and the inlet 61, overflow 62, and outlets 63 are all connected to the buffer chamber. The buffer chamber buffers and diverts the incoming coffee, preventing it from splashing out of the outlets 63. This design ensures the stability and uniformity of the flow rate during coffee making. The overflow 62 of the coffee interface assembly 6 primarily functions to vent air and ensure that coffee flows out of the outlets 63, preventing air bubbles in the buffer chamber and ensuring coffee quality. Furthermore, lighting elements 64 are provided on both sides of the coffee interface assembly 6. These lighting elements 64 can be sensor lights or automatically illuminate when the coffee machine is started, providing convenience for users operating at night or in low-light environments.

[0044] This utility model also provides a beverage device, including a beverage outlet component. This beverage device is a coffee machine with a milk-making function.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
