Description

Technical Field

[0001] This utility model relates to the field of beverage preparation technology, and in particular to an emulsification device and a beverage machine. Background Technology

[0002] To create milk foam, existing beverage machines typically have a foaming device on the front for preparing frothy or hot milk. This device includes a milk delivery pipe, an air pipe, a steam pipe, and a mixing chamber. Both the air and steam pipes are connected to the milk delivery pipe, as is the mixing chamber, which is connected to the milk outlet. The foaming device works on the Venturi principle: steam enters the milk delivery pipe through the steam pipe, creating negative pressure that draws in milk from the milk container and mixes it with external air to form foam. The foam then flows out from the milk outlet of the mixing chamber, allowing it to be used to make cappuccinos.

[0003] Currently, on the same beverage machine, in order to obtain milk foam of different qualities or temperatures to adapt to different scenarios, the user operation is very troublesome or the control program inside the beverage machine is very complicated. Utility Model Content

[0031] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0032] It should be understood that terms such as "above," "over," "below," and "below" used in this document to indicate relative spatial positions are for ease of explanation in describing the relationship between one unit or feature and another unit or feature as shown in the accompanying drawings. The term "relative spatial position" may be intended to include different orientations of the equipment besides those shown in the figures during use or operation. In emulsification equipment based on the Venturi effect, the adjustment of milk foam temperature and quality is generally achieved by adjusting the dimensions of the milk inlet and air inlet. Adjusting the milk inlet and air inlet typically requires two separate devices for adjustment, resulting in a complex structure and high cost. Furthermore, when only the size of the milk inlet is adjusted, only the milk flow is controlled, but the air flow remains constant. When the milk flow decreases, the foaming rate increases, and the milk foam quality changes. Conversely, the same applies. Therefore, after adjusting the milk inlet, the air inlet also needs to be adjusted accordingly, which is also cumbersome. The emulsification equipment in this specific embodiment of the present invention is illustrated using an emulsification equipment for a beverage machine 10 as an example. (Refer to...) Figures 1 to 4 As shown, in this embodiment, the emulsification device includes a mixing element 30, which has a venturi structure.

[0033] The venturi structure includes a steam channel 31 and a negative pressure chamber 32. The steam channel 31 is used to connect to a steam source, and the negative pressure chamber 32 is located at the outlet end of the steam channel 31. The steam generated by the steam source flows through the steam channel 31 to form a negative pressure in the negative pressure chamber 32. The negative pressure chamber 32 has a fluid inlet 321 and a fluid outlet 322. The fluid inlet 321 is used to connect to a liquid source.

[0034] The Venturi structure is a fluid acceleration and pressure reduction structure. In this embodiment, high-speed steam generated by the steam source flows through the steam channel 31, forming a negative pressure chamber 32 at the outlet end of the steam channel 31. Since the negative pressure chamber 32 is connected to the liquid source, the negative pressure within the negative pressure chamber 32 can draw liquid from the liquid source. Under the action of negative pressure, the liquid from the liquid source enters the negative pressure chamber 32 from the fluid inlet 321, mixes with the steam output from the steam channel 31, and flows out from the fluid outlet 322, achieving an emulsification effect.

[0035] The emulsification device 100 also includes a mixing chamber 34, which is connected to a negative pressure chamber 32 via a fluid outlet 322. The mixed fluid flowing out of the negative pressure chamber 32 can be further mixed in the mixing chamber 34. The mixing chamber 34 provides additional space for the mixing of steam and liquid, or steam, air and liquid, ensuring that they are fully mixed to form a uniform and fine mixed fluid.

[0036] When the liquid source is milk, the mixing chamber 34 can ensure that steam, air and milk are fully mixed, flow stably, heat evenly, and adjust the texture of milk foam, thereby improving the quality of milk foam.

[0037] An adjusting member 40 is provided between the mixing chamber 34 and the fluid outlet 322. The adjusting member 40 includes multiple through holes 42 with different diameters. The adjusting member 40 can be selectively moved relative to the mixing element 30 to adjust the different through holes 42 to connect the fluid outlet 322 and the mixing chamber 34, thereby changing the negative pressure in the negative pressure chamber 32.

[0038] Unlike a fixed venturi structure, in order to overcome the problem that users cannot adjust the temperature or quality of the mixed fluid according to their own needs, the emulsification device 100 of this application is provided with an adjusting element 40 between the mixing chamber 34 and the fluid outlet 322.

[0039] The regulating component 40 is provided with multiple through holes 42 of different diameters. By selectively connecting the fluid outlet 322 and the mixing chamber 34 through holes 42 of different diameters, the flow area between the fluid outlet 322 and the mixing chamber 34 can be changed, thereby adjusting the negative pressure in the negative pressure chamber 32. The inlet diameter of the mixing chamber 34, i.e., the size of the through hole 42, directly affects the negative pressure in the negative pressure chamber 32.

[0040] Specifically, when the diameter of the through hole 42 increases, the flow area between the negative pressure chamber 32 and the mixing chamber 34 increases, and the negative pressure in the negative pressure chamber 32 decreases; conversely, when the diameter of the through hole 42 decreases, the flow area between the negative pressure chamber 32 and the mixing chamber 34 decreases, and the negative pressure in the negative pressure chamber 32 increases.

[0041] Since the negative pressure of the negative pressure chamber 32 directly affects the amount of liquid drawn in from the liquid source, the amount of fluid drawn into the negative pressure chamber 32 can be adjusted by adjusting the aperture of the through hole 42.

[0042] With the steam volume remaining constant, the amount of fluid drawn into the negative pressure chamber 32 decreases, the steam ratio increases, and the temperature of the mixed fluid in the mixing chamber 34 also increases, thereby achieving an increase in the final output temperature of the mixed fluid; conversely, the amount of liquid drawn into the negative pressure chamber 32 increases, the steam ratio decreases, and the temperature of the mixed fluid in the mixing chamber 34 also decreases, thereby achieving a decrease in the final output temperature of the mixed fluid.

[0043] Users can easily change the diameter of the through-hole 42 entering the mixing chamber 34 by simple operations, such as rotating or sliding the adjusting component 40, or by triggering the automatic control of the adjusting component 40. This allows them to select their preferred output fluid temperature according to different settings, meeting various user needs. Furthermore, the diameters of the multiple through-holes 42 are pre-adjusted at the factory, allowing different through-hole diameters to correspond to different temperatures / qualityes of milk (foam). This effectively reduces the professional requirements for users to adjust the quality / temperature of the milk foam, making operation more convenient.

[0044] In one embodiment, the emulsification apparatus 100 further includes a housing 60 that houses the mixing element 30, and an adjustment member 40 connected to an operation part 41, which is at least partially disposed outside the housing 60 for adjusting the position of the adjustment member 40 relative to the mixing element 30.

[0045] The outer casing 60 can house the core components such as the mixing element 30, forming a complete and aesthetically pleasing whole. While effectively protecting the internal components, it can also serve as an independent device to facilitate cooperation with the main body of the beverage machine 10.

[0046] The operating part 41 can be a component operated by the user, such as a knob, lever, button, etc. The operating part 41 can also be part of the adjusting element 40, facilitating assembly with the mixing element 30. By partially or entirely placing the operating part 41 outside the housing 60, the user can directly touch the operating part 41 and adjust the position of the adjusting element 40 relative to the mixing element 30 by controlling the operating part 41, thereby conveniently and quickly changing the negative pressure within the negative pressure chamber 32 to adjust the emulsification effect.

[0047] For example, users can easily rotate the adjustment member 40 through the operating part 41 on the outside of the housing 60 to switch between different gears and select the desired milk foam temperature or quality.

[0048] In one embodiment, the steam passage 31 defines a first axis X, and the adjusting member 40 is rotatable relative to the mixing element 30, with the rotation axis R of the adjusting member 40 being parallel to the first axis X.

[0049] In order to further simplify the structure and operation of the adjusting member 40, and to make the mixing element 30 more compact and the adjusting member 40 more reliable, this embodiment limits the movement mode of the adjusting member 40.

[0050] Specifically, the adjusting element 40 is designed to rotate relative to the mixing element 30, which is easy to implement and can effectively reduce the number and complexity of moving parts, thereby simplifying the structure of the entire emulsification equipment 100, reducing manufacturing costs, and improving reliability.

[0051] The steam channel 31 serves as the steam flow channel in the emulsification equipment 100, and its axis can be used as a baseline for the equipment structure. Setting the rotation axis R of the regulating member 40 parallel to the first axis X of the steam channel 31 allows the rotational movement direction of the regulating member 40 to be coordinated with the steam flow direction, resulting in a more rational and compact structural layout. This parallel axis setting also helps simplify the motion transmission from the operating part 41 to the regulating member 40.

[0052] In one embodiment, a mixing chamber 34 is disposed on a mixing element 30, and a slot 33 is provided on the mixing element 30. The mixing chamber 34 and the negative pressure chamber 32 are separated by the slot 33, and the adjusting member 40 is movably disposed in the slot 33.

[0053] In order to make the structure of the emulsification device 100 more integrated and compact, the mixing chamber 34 is directly set on the mixing element 30, that is, the mixing element 30 is provided with the negative pressure chamber 32 and the mixing chamber 34, or the mixing chamber 34 is integrated within the mixing element 30.

[0054] Meanwhile, a slot 33 is provided on the mixing element 30. The slot 33 can be understood as a groove-like structure opened on the mixing element 30 to accommodate and guide the movement of the regulating member 40. The slot 33 spatially separates the mixing chamber 34 and the negative pressure chamber 32. The regulating member 40 is set in the slot 33, so that after the steam forms a negative pressure in the negative pressure chamber 32, it can effectively enter the mixing chamber 34 from the fluid outlet 322 through the through hole 42 on the regulating member 40.

[0055] The adjusting member 40 is movably disposed within the slot 33, meaning that the adjusting member 40 can move along the slot 33, for example, by rotating or sliding. This movable arrangement means that the adjusting member 40 can be controllably displaced relative to the mixing element 30 under the guidance of the slot 33, thereby achieving the purpose of connecting the through hole 42 required for adjustment with the fluid outlet 322.

[0056] Integrating the mixing chamber 34 and the negative pressure chamber 32 onto the mixing element 30, and using a slot 33 for functional separation and motion guidance, with the adjusting element 40 positioned within the slot 33, allows for a more compact overall structure of the emulsifying device 100, clearer relative positions between elements, easier assembly, and facilitates precise adjustment and control. The slot 33 also provides precise guidance and accommodating space for the movement of the adjusting element 40, ensuring its smoothness and reliability.

[0057] Reference Figure 5 In one embodiment, along the extension direction of the steam passage 31, the adjusting member 40 includes a rotating shaft 43 that protrudes to both sides respectively, and the slot 33 includes a first end 331 and a second end 332 opposite to each other. The first end 331 and the second end 332 are respectively provided with a claw 333. The claw 333 has an opening 334, and the rotating shaft 43 is engaged with the claw 333 through the opening 334.

[0058] The above method can achieve a reliable and convenient connection between the adjusting member 40 and the mixing element 30, and ensure that the adjusting member 40 can rotate relative to the mixing element 30 around a specific axis.

[0059] Specifically, along the extension direction of the steam passage 31, i.e. the direction of steam jetting, the regulating member 40 is configured to include rotating shafts 43 protruding to both sides. These two rotating shafts 43 extend outward from both sides of the body 47 of the regulating member 40, serving as a pivot structure for connecting the regulating member 40 to the mixing element 30.

[0060] Meanwhile, the slot 33 that cooperates with the adjusting member 40 has also been adapted in its structure. The first end 331 and the second end 332 of the slot 33 are respectively provided with a claw 333 structure. The claw 333 is a structure with a certain degree of elasticity, and an opening 334 is provided on the claw 333. The opening 334 is provided to facilitate the rotation shaft 43 of the adjusting member 40 to be engaged into the inside of the claw 333 through the opening 334.

[0061] During assembly, the rotating shaft 43 of the adjusting component 40 can be aligned with the opening 334 of the pawl 333 and a certain pressure can be applied so that the rotating shaft 43 overcomes the elastic deformation of the pawl 333 and finally gets into the pawl 333, where it is firmly gripped and limited by the pawl 333.

[0062] Through this cooperative structure of rotating shaft 43 and pawl 333, quick installation and reliable connection between adjusting component 40 and mixing element 30 can be achieved.

[0063] The opening 334 of the chuck 333 allows the rotating shaft 43 to be easily inserted from the side without complicated tools or operations, reducing assembly difficulty and improving assembly efficiency.

[0064] Once the rotating shaft 43 is engaged with the pawl 333, the elastic structure of the pawl 333 ensures that the rotating shaft 43 is firmly fixed in the slot 33, preventing the adjusting part 40 from accidentally falling off during use and ensuring the reliability and stability of the connection.

[0065] At the same time, this connection method also allows the adjusting member 40 to rotate freely relative to the mixing element 30 around the axis of the rotating shaft 43, thereby adjusting the communication state between the through hole 42 and the fluid outlet 322 to achieve the purpose of adjusting the emulsification effect.

[0066] Reference Figure 6 In one embodiment, the bottom surface 335 of the slot 33 is constructed as an arc surface, and the adjusting member 40 is matched with the arc surface shape and rotates relative to the mixing element 30 along the arc surface.

[0067] To further improve the user's operational feel and smoothness when adjusting the emulsifying equipment 100, and to reduce stuttering during the adjustment process, this embodiment optimizes the shape of the bottom surface 335 of the slot 33. An arc surface is a curved surface whose radius of curvature can be designed according to actual needs; for example, a circular arc surface, an elliptical arc surface, or other suitable arc shapes can be used.

[0068] At the same time, in order to match the curved bottom surface 335, the bottom of the adjusting member 40 or the part that contacts the bottom surface 335 of the slot 33 is also designed to be a curved surface shape that matches the curved shape.

[0069] For example, if the bottom surface 335 of the slot 33 is an arc surface, then the bottom of the adjusting member 40 is also designed to be an arc surface with the same or similar curvature.

[0070] With the arc-shaped slot 33 bottom surface 335 and the corresponding bottom shape design of the adjustment member 40, when the user operates the adjustment member 40 to rotate relative to the mixing element 30, the adjustment member 40 can slide smoothly along the arc surface, just like moving on a smooth curved surface.

[0071] The curved surface contact makes the rotation of the adjustment component 40 smoother and easier, allowing users to adjust the gears more easily and freely, resulting in a better operating experience. Furthermore, the curved structure may also help maintain the stability of the adjustment component 40 during rotation, reducing wobbling or jamming.

[0072] Of course, in other possible implementations, the adjustment member 40 and the bottom surface 335 of the slot 33 can be set to point contact or line contact. For example, the adjustment member 40 can roll smoothly along the arc surface, which can effectively reduce the contact area between the adjustment member 40 and the bottom surface 335 of the slot 33, reduce frictional resistance, and avoid obvious frictional jerking.

[0073] In one embodiment, the slot 33 is provided with a positioning recess 336, and the adjusting member 40 is provided with a positioning protrusion 46. The positioning protrusion 46 corresponds to at least one through hole 42. The through hole 42 has an activated position that connects the fluid outlet 322 and the mixing chamber 34. The positioning protrusion 46 is engaged with the positioning recess 336 to keep the through hole 42 in the activated position.

[0074] In order to achieve precise control and stable maintenance of the 100 gear levels of the emulsification equipment, and to prevent users from accidentally touching or sliding the gear level during operation, this embodiment is specially designed with a positioning mechanism.

[0075] The positioning mechanism is mainly composed of a positioning recess 336 set in the slot 33 and a positioning protrusion 46 set on the adjusting member 40, which cooperate with each other.

[0076] The positioning recess 336 can be a recess or hole structure provided on the inner wall or bottom surface 335 of the slot 33, while the positioning protrusion 46 is a structure that protrudes from the surface of the adjusting member 40, such as a protrusion, a bump, a rib, etc.

[0077] The position of the positioning protrusion 46 needs to correspond to the position of at least one through hole 42, and the through hole 42 is in the enabled position connecting the fluid outlet 322 and the mixing chamber 34.

[0078] The term "activated position" refers to the position where, when the adjusting member 40 is rotated to a specific angle or position, the through hole 42 is precisely aligned with and connects the fluid outlet 322 and the mixing chamber 34, thereby enabling the emulsifying device 100 to operate at the corresponding gear.

[0079] When the adjusting member 40 is rotated to a certain position, so that the through hole 42 is in the activated position aligned with the fluid outlet 322, the positioning protrusion 46 provided on the adjusting member 40 will fit precisely into the positioning recess 336 provided in the slot 33.

[0080] This locking action can produce a certain damping or locking sensation, clearly indicating to the user that the current gear has been switched into position.

[0081] More importantly, once the positioning protrusion 46 engages with the positioning recess 336, the interaction force between the two can effectively prevent the adjusting member 40 from continuing to rotate or from accidentally sliding, thereby keeping the adjusting member 40 stably in the current active position and ensuring that the emulsifying device 100 continues to work at the user-set level without easily changing.

[0082] For example, a positioning protrusion 46 with a convex structure is provided on the adjusting member 40, and a positioning recess 336 with a groove structure is provided on the mixing element 30. Through the cooperation of the protrusion and the groove, it is clear that the adjusting member 40 has been rotated to the corresponding gear when it is rotated, and the gear is kept stable through the locking action.

[0083] Reference Figure 7 In one embodiment, the multiple through holes 42 with different diameters include a first through hole 421, a second through hole 422 and a third through hole 423. The second through hole 422 and the third through hole 423 are respectively disposed on both sides of the first through hole 421. The positioning protrusion 46 corresponds to the position of the first through hole 421. The adjusting member 40 includes a first end wall 441 and a second end wall 442 disposed opposite to each other along the arrangement direction of the through holes 42. The emulsifying device 100 also includes a housing 60 for accommodating the mixing element 30. The first end wall 441 and the second end wall 442 abut against the housing 60 to position the second through hole 422 and the third through hole 423 in the activation position.

[0084] In order to achieve precise adjustment and positioning of multiple gears, such as three gears, this embodiment has further refined the design of the number of through holes 42 and the positioning mechanism.

[0085] Specifically, three different sizes of through holes 42 are provided: a first through hole 421, a second through hole 422, and a third through hole 423, to achieve three different gear adjustments. For example, the first through hole 421 can be designed as the middle gear, while the second through hole 422 and the third through hole 423 can be designed as the high gear and the low gear, respectively, or vice versa.

[0086] To achieve precise positioning of these three positions, this embodiment employs a clever combination positioning method. For the middle position, i.e., the activation position of the first through hole 421, the positioning recess 336 and the positioning protrusion 46 are still used in combination. For the other two positions, i.e., the activation positions of the second through hole 422 and the third through hole 423, a positioning method that abuts against the outer casing 60 is adopted.

[0087] Specifically, when the adjusting member 40 is rotated to the activated position of the second through hole 422 or the third through hole 423, the first end wall 441 or the second end wall 442 will abut against the housing 60 that houses the mixing element 30, respectively. The abutting force between the end wall and the housing 60 is used to position the second through hole 422 and the third through hole 423 to be activated.

[0088] By combining the positioning protrusion 46 / positioning recess 336 with the abutment of the end wall / outer shell 60, reliable positioning of three gear positions can be achieved with a relatively simple structure. The middle gear position is precisely locked using the positioning protrusion 46 / positioning recess 336, while the upper and lower gear positions cleverly utilize the structure of the outer shell 60, achieving positioning through the abutment of the end wall of the adjusting member 40 against the outer shell 60. This eliminates the need for additional positioning components, simplifying the complexity of the positioning structure and making the overall structure more compact while ensuring positioning reliability.

[0089] In one embodiment, the housing 60 includes a top surface 601 and a side surface, with the opening of the slot 33 facing the top surface 601 and a portion of the adjusting member 40 exposed from the top surface 601; or the opening of the slot 33 faces the side surface and a portion of the adjusting member 40 exposed from the side surface.

[0090] To improve the structural layout flexibility and design adaptability of the emulsification equipment 100 in different application scenarios, this embodiment provides two selectable solutions for the opening direction of the slot 33 and the corresponding exposed position of the adjustment component 40.

[0091] The housing 60 is used to house and protect internal components such as the mixing element 30, and it typically has multiple surfaces, such as a top surface, side surfaces, bottom surface, etc.

[0092] Alternatively, the opening of the slot 33 can face the top surface 601. This means that a clearance hole corresponding to the slot 33 is provided on the top surface 601 of the housing 60, allowing the user to observe or touch the adjusting member 40 from the top surface 601 of the housing 60. In this case, a portion of the adjusting member 40, such as the operating part 41, can be designed to be exposed from the clearance hole on the top surface 601.

[0093] When operating, the user can operate the adjustment member 40 from the top surface 601 of the housing 60, for example, by rotating or turning the operating part 41 of the adjustment member 40.

[0094] Alternatively, the opening of the slot 33 can also face the side. Unlike the first option, the clearance hole 622 corresponding to the slot 33 is provided on the side of the housing 60. Accordingly, a part of the adjusting member 40, such as the operating part 41, can be designed to be exposed from the side. The user can operate the adjusting member 40 from the side of the housing 60.

[0095] These two schemes offer different structural layouts, allowing designers to flexibly choose the appropriate orientation of the slot 33 opening and the exposed position of the adjustment component 40 based on factors such as the product's specific application scenario, operating habits, appearance design, and space constraints.

[0096] For example, if the product requires a more spacious top operating space, or is more in line with the user's downward operating habits, the solution with the slot 33 opening facing the top surface 601 can be selected; conversely, if the product needs to be more convenient to operate from the side, or in order to achieve a specific appearance effect, the solution with the slot 33 opening facing the side can be selected.

[0097] In one embodiment, the housing 60 includes opposing first side 603 and second side 604, the mixing element 30 is adjacent to the first side 603, and the steam passage 31 extends parallel to the first side 603. The rotation axis R of the adjusting member 40 is biased toward the first side 603, and a portion of the adjusting member 40 is exposed from the first side 603.

[0098] In order to adapt to the case of the housing 60 and further optimize the structural layout of the emulsification equipment 100 to make it more compact and easier for users to operate from the side, this embodiment defines the positional relationship of the mixing element 30, the steam channel 31 and the regulating member 40 relative to the housing 60.

[0099] Specifically, the outer casing 60 is designed to include opposing first side 603 and second side 604. Here, "first side 603" and "second side 604" refer to two opposing sides of the outer casing 60, such as left and right sides or front and back sides. The steam passage 31 extends parallel to the first side 603, meaning that the direction of steam flow is consistent with the direction of the first side 603 of the outer casing 60, or in other words, the steam passage 31 extends along the direction of the first side 603.

[0100] In this housing 60 structure, the mixing element 30 is positioned adjacent to the first side 603, meaning the mixing element 30 is closer to the first side 603 of the housing 60 in the horizontal direction. Simultaneously, to match the structural layout of the side and adapt to the rotation adjustment method, and to facilitate user operation from the first side 603, the rotation axis R of the adjusting member 40 is offset towards the first side 603.

[0101] "Offset" means that the rotation center of the adjustment member 40 is not located at the center of the mixing element 30, but is offset by a certain distance relative to the center of the mixing element 30 towards the first side 603.

[0102] This offset design allows a portion of the adjusting member 40 to be exposed from the first side 603, making the overall structure of the emulsifying device 100 more compact. Especially when the side of the housing 60 is provided with a clearance hole 622, this layout can effectively utilize space and reduce the overall size of the device.

[0103] In addition, the operation part 41 of the adjustment component 40 is located on the first side 603 of the housing 60, which also makes it easier for users to operate from the side. Especially in application scenarios such as beverage machine 10, when the front space of the device is limited, side operation may be more ergonomic and more convenient and faster.

[0104] In one embodiment, the adjusting member 40 includes a body 47 and a sealing ring 425 disposed on the body 47. The sealing ring 425 is disposed at both ends of the through hole 42. The body 47 is made of a rigid material, and the sealing ring 425 is made of a flexible material.

[0105] For example, the body 47 and the sealing ring 425 are integrally formed.

[0106] In order to further improve the performance and reliability of the adjusting member 40 and optimize its structure and manufacturing process, this embodiment provides a more detailed description of the material and structure of the adjusting member 40.

[0107] The main body 47 constitutes the main structure of the adjusting member 40, which is the main part for bearing strength and realizing function, while the sealing ring 425 is an auxiliary component set up to achieve a good sealing effect.

[0108] To meet the different functional requirements of the body 47 and the sealing ring 425, different materials were used to manufacture the body 47 and the sealing ring 425 respectively.

[0109] The body 47 is made of a rigid material. "Rigid material" refers to a material with high hardness and strength, such as rigid plastic. Using a rigid material to make the body 47 ensures that the adjusting component 40 has sufficient strength and rigidity, is not easily deformed or damaged, and thus ensures that it can maintain stable performance and reliability during long-term use.

[0110] The sealing ring 425 is made of a flexible material. "Flexible material" refers to a material with good elasticity and flexibility, such as flexible plastics, rubber, silicone, or other elastomers. Using a flexible material to make the sealing ring 425 allows for the formation of a tight seal between the adjusting component 40 and the mixing element 30 or other components, effectively preventing liquid or gas leakage from gaps.

[0111] In addition, sealing rings 425 are provided at both ends of the through hole 42, that is, sealing rings 425 are provided at both the inlet and outlet ends of the through hole 42 to achieve more comprehensive sealing protection and prevent liquid leakage when flowing through the through hole 42.

[0112] In one embodiment, the adjusting member 40 is configured as a fan shape, and the operating part 41 is configured as a fan handle that protrudes radially from the center of the fan shape, with the fan handle protruding outside the outer casing 60.

[0113] In order to further optimize the structural shape of the adjustment member 40 and the operation part 41, making them more ergonomic and more intuitive and convenient to operate, this embodiment has made specific designs on the shape of the adjustment member 40 and the operation part 41.

[0114] A sector is a regular geometric shape characterized by a certain curvature and radius, with a central angle less than 360 degrees. Designing the adjusting component 40 as a sector allows for better matching with the motion trajectory of the rotation adjustment, enabling the edge contour of the adjusting component 40 to better conform to the slot 33 or other mating structures on the mixing element 30 during rotation, resulting in a more rational and compact structure.

[0115] At the same time, the fan shape is easy to manufacture and process, and can be mass-produced using molding processes such as injection molding and stamping.

[0116] In conjunction with the fan-shaped adjustment member 40, this embodiment constructs the operating part 41 as a fan handle that protrudes radially from the center of the fan shape. The fan handle is a slender rod-shaped or plate-shaped structure that extends outward in the radial direction from the center of the fan shape.

[0117] The fan handle is used as the operating part 41. Its structure is simple and intuitive, and users can easily understand its operation. That is, by grasping the fan handle and rotating it around the center of the fan, the adjusting part 40 can be driven to rotate.

[0118] In addition, to facilitate operation by the user outside the housing 60, the fan handle is designed to protrude outside the housing 60.

[0119] This means that at least a portion of the fan handle, such as the operating end, is exposed outside the housing 60, allowing the user to directly touch the fan handle and apply operating force without opening the housing 60 or performing any other additional operations. For example, the user can switch speeds and adjust the emulsification effect by pinching the fan handle with their fingers and gently rotating it up and down.

[0120] The combined design of the fan-shaped adjustment component 40 and the fan-handle type operating part 41 makes the operation of the emulsification equipment 100 more intuitive, convenient, and user-friendly. The fan shape naturally matches the rotation trajectory, making the structure more reasonable; the fan-handle type operating part 41 has a simple structure, is easy to grip and operate, and extends outside the outer shell 60, making operation even more convenient.

[0121] In one embodiment, the housing includes a side cover 62 and a housing 61 connected to the side cover 62. The housing 61 defines a liquid-containing cavity for holding a liquid source. An upper cover 611 is provided on the housing 61 to cover the upper opening of the housing 61. A mixing element 30 is disposed on the side cover 62, and an adjusting member 40 is disposed on the side cover 62 and protrudes into the external space.

[0122] The side cover 62 includes a cover plate 621 for covering at least a portion of the mixing element 30. The side cover 62 and the housing 61 together define a liquid inlet channel 612 communicating with the liquid chamber, which in turn communicates with the fluid inlet 321. The mixing element 30 can be integrated into the side cover 62. An adjusting member 40 is mounted on the side cover 62 and partially protrudes into the external space for easy user operation. The user can directly control different through-holes 42 connecting the fluid outlet 322 and the mixing chamber 34 via the adjusting member 40, thereby adjusting the negative pressure of the negative pressure chamber 32 and achieving precise control of the amount of liquid and gas-liquid intake.

[0123] The above embodiments illustrate some implementations of the operation unit 41. The operation unit 41 can also be in other ways, such as control buttons, operation panels, etc. For example, the motor drives the adjustment member 40 to move through the transmission mechanism. The user only needs to select the desired beverage temperature on the operation panel, and the position of the adjustment member 40 relative to the mixing element 30 is automatically controlled according to the system's predetermined algorithm.

[0124] Reference Figure 8 In one embodiment, a beverage machine 10 is also provided, including the emulsification device 100 of any of the above embodiments. The beverage machine 10 includes a front panel 11 with a beverage outlet 12. The front panel 11 is provided with an installation interface 13. An emulsification device is detachably connected to the front panel 11 and located on one side of the beverage outlet 12. A steam source is provided in the beverage machine 10. The steam generated by the steam source can be delivered to the installation interface 13. The steam channel 31 is connected to the installation interface 13.

[0125] The beverage machine 10 typically includes a front panel 11 for providing a beverage outlet 12 from which a user can collect a prepared beverage.

[0126] This means that the various emulsifying devices 100 with adjustable emulsification effects described in the foregoing embodiments can all be applied to the beverage machine 10 of this embodiment as an important component of the beverage machine 10 for making milk foam or other emulsified beverage ingredients. By adopting the aforementioned emulsifying devices 100, the beverage machine 10 can also achieve adjustable emulsification effects; for example, users can adjust the temperature, fineness, etc. of the milk foam according to their personal preferences.

[0127] To facilitate user maintenance, cleaning, or replacement of the emulsification equipment 100, this embodiment further designs the emulsification setup to be detachably connected to the front panel 11.

[0128] "Detachable connection" means that the emulsifying device 100 and the front panel 11 of the beverage machine 10 are connected in a detachable manner, such as by snap-fit ​​connection, screw connection, plug-in connection, etc.

[0129] When users need to clean, repair or replace the emulsifying device 100, they do not need to disassemble the entire beverage machine 10. They can simply remove the emulsifying device 100 from the front panel 11. The operation is simple and quick, which greatly improves the maintenance convenience of the beverage machine 10.

[0130] For example, after a period of use, the emulsifying equipment 100 may accumulate dirt or become clogged inside. At this time, the user can disassemble the emulsifying equipment 100 for cleaning, and then reinstall it to restore the normal function of the beverage machine 10.

[0131] Alternatively, if the emulsification equipment 100 malfunctions and needs to be replaced, the user can easily disassemble it and replace it with a new emulsification equipment 100 without the need for professional personnel to come to the site for repair.

[0132] In order to optimize the structural layout of the beverage machine 10 and make the fit between the beverage outlet 12 and the emulsification component more compact and reasonable, this embodiment also limits the emulsification device 100 to one side of the beverage outlet 12.

[0133] "One side" refers to the emulsification equipment 100 being located next to the beverage outlet 12 in the horizontal direction, which can be the left, right, or other relative positions.

[0134] By placing the emulsifying device 100 on one side of the beverage outlet 12, the beverage preparation process can be made smoother. For example, the milk foam produced by the emulsifying device 100 can be directly injected from one side into the coffee or other beverages flowing out of the beverage outlet 12 to mix and form the final beverage.

[0135] This layout may also make the overall structure of the beverage machine 10 more compact and its appearance more harmonious and aesthetically pleasing. In addition, placing the emulsifying device 100 on one side of the beverage outlet 12 may also make it easier for users to observe the emulsification process. For example, users can clearly see milk foam being generated from the emulsifying device 100 and injected into the beverage.

[0136] The emulsifying device connects to the beverage machine 10 via the mounting interface 13 on the front panel 11, enabling communication of steam and control signals. It uses a steam source and a liquid source to create milk foam or hot milk, which is then delivered to the user's cup for mixing with the coffee. By seamlessly integrating the emulsifying device with the beverage machine 10, users can complete the entire process from coffee preparation to milk foam addition on a single device, enhancing the functionality and convenience of the equipment. This flexible connection method not only improves the overall applicability of the beverage machine 10 but also provides users with a richer beverage preparation experience, further satisfying personalized and diverse consumer demands.

[0137] The emulsification equipment described above is not limited to use in beverage machine 10, but can also be used in other beverage brewing devices, such as tea machines or other devices for brewing beverages.

[0138] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0139] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
