[0048] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0050] This utility model provides a beverage preparation device for preparing hot drinks. Specifically, the beverage preparation device can be a fully automatic coffee machine, a soy milk maker, etc., with grinding and brewing functions, or a capsule coffee machine, a soy milk maker, etc., that prepares beverages by mixing pre-made raw material powders. In this embodiment, a coffee machine is used as an example for illustration.

[0051] Please see Figures 1 to 10 The present invention also provides a steam export device 100, which can be installed on the body of a beverage preparation equipment and can be connected to a steam generator in the body, so as to export high-temperature steam according to the beverage preparation requirements, so that the high-temperature steam heats the milk while mixing with the milk and air to form milk foam.

[0052] Specifically, please refer to Figures 1 to 3 The steam extraction device 100 includes a body 10, a first mounting member 20, and a second mounting member 30. A cavity 11 is formed within the body 10, and an outlet communicating with the cavity 11 and two openings 12 are provided. The two openings 12 are respectively located on opposite sides of the body 10 in the lateral direction. Specifically, the body 10 has two mounting sides 13 arranged opposite each other in the lateral direction, and the two openings 12 are respectively provided on the two mounting sides 13. In this embodiment, the specific structure of the body 10 is not limited, as long as steam can be introduced into the cavity 11 through one of the openings 12 and allowed to flow out through the outlet. It can be understood that a conduit 50 is connected to the outside of the body 10, the conduit 50 communicating with the outlet and preferably located below the body 10, to introduce steam into the beverage.

[0053] It should be noted that in this embodiment, the lateral direction is roughly parallel to the horizontal direction. The outlet can be opened on the periphery of the body 10 or on the lower side of the body 10. It is preferred that the outlet be opened on the lower side of the body 10 to reduce the possibility of residual liquid in the cavity 11.

[0054] Furthermore, the first mounting member 20 has an inlet channel 21 formed therein, which is used to connect to the steam generating device and can be selectively installed on one side of the body 10 in the lateral direction, so that the inlet channel 21 connects to one of the two openings 12. The second mounting member 30 can be selectively installed on the other side of the body 10 in the lateral direction to block the opening 12 on the other side of the body 10. In this embodiment, the two openings 12 can be arranged in a through manner in the lateral direction, and depending on the installation position of the first mounting member 20 and the second mounting member 30 relative to the body 10, one opening 12 is used to introduce steam into the cavity 11, and the other opening 12 is correspondingly blocked. That is to say, in this embodiment, the installation positions of the first mounting member 20 and the second mounting member 30 relative to the body 10 can be interchanged.

[0055] In this embodiment, the steam export device 100 can more flexibly select the installation position of the steam export device 100 relative to the machine body according to the actual installation conditions, and adjust the connection position of the inlet channel 21 and the main body 10 according to the arrangement of the internal functional components and the internal space of the machine body, that is, change the installation position of the first mounting part 20 and the second mounting part 30, so as to adapt to different placement positions of the beverage preparation equipment and the operator's habits, and improve the inconvenience caused by the fixed installation position of the existing steam export device 100.

[0056] Further, please refer to Figure 1 and Figure 2 The steam extraction device 100 also includes a bracket 40, which is used to fix the body of the beverage preparation equipment. The main body 10 is detachably mounted on the bracket 40. In this embodiment, the bracket 40 can be installed inside or outside the body, but it is preferably detachably mounted to the body to facilitate adjustment of the installation position of the steam extraction device 100 and maintenance and replacement of the steam extraction device 100.

[0057] The specific structure of the support 40 is not limited; please refer to further information. Figure 2 The bracket 40 has two mounting walls 41 arranged side by side in the horizontal direction. The body 10 is detachably clamped between the two mounting walls 41. Each mounting wall 41 corresponds to one of the two mounting sides 13 of the body 10 and is provided with a through hole 42 aligned with the opening 12 on the body 10. The first mounting member 20 is sequentially inserted through one of the two through holes 42 and the opening 12 corresponding to the through hole 42, so that the inlet channel 21 connects to one of the two openings 12. In a preferred embodiment, the two mounting walls 41 are connected only on the rear and bottom sides to maintain their rigidity. This design makes the steam export device 100 more convenient to maintain and install, improves the convenience of maintaining the beverage preparation equipment, and enhances the overall stability of the beverage export device.

[0058] Further, the first mounting component 20 includes a pipe 22 having an inlet end 221 and an outlet end 222. An inlet channel 21 is formed within the pipe 22, connecting the inlet end 221 and the outlet end 222. The first mounting component 20 can be selectively installed close to one of the two mounting walls 41, and the pipe 22 passes sequentially through the through hole 42 and the corresponding opening 12 on the adjacent mounting wall 41 from its outer side, so that the outlet end 222 is inserted into the cavity 11. In this installation, the body 10 can be inserted between the two mounting walls 41 from the front and / or top of the bracket 40, and then the first mounting component 20 is inserted into the opening 12 through the through hole 42, thus connecting the first mounting component 20 to the body 10. The operation is simple and reliable, and the bracket 40 also serves as a limiting and guiding function, ensuring that the first mounting component 20 can accurately mate with the body 10.

[0059] Please refer to the following: Figures 3 to 5 ,as well as Figure 9 The outer periphery of the pipe 22 is provided with an annular boss 223. The end face of the annular boss 223 near the outlet end 222 abuts against the body 10 and is attached to the outer side of the corresponding opening 12. The outer peripheral surface of the annular boss 223 abuts against the inner peripheral wall of the corresponding through hole 42. In this embodiment, the annular boss 223 serves to limit and engage with the through hole 42.

[0060] Preferably, a first annular groove 224 is formed on the outer periphery of the pipe 22. The first annular groove 224 is disposed between the annular protrusion 223 and the outlet end 222. The first mounting member 20 also includes a sealing ring 60 sleeved on the outer periphery of the pipe 22, and the sealing ring 60 is engaged in the first annular groove 224. It can be understood that multiple first annular grooves 224 and sealing rings 60 can be provided, and multiple sealing rings 60 are spaced apart along the length direction of the pipe 22 to improve the sealing performance of the opening 12 of the pipe 22. This design enhances the sealing effect and effectively prevents steam leakage.

[0061] Furthermore, the pipe 22 includes a first pipe section 23 and a second pipe section 24 connected sequentially from the inlet end 221 to the outlet end 222. The second pipe section 24 is provided with the annular boss 223. The first pipe section 23 bends and extends rearward from the end of the second pipe section 24 away from the outlet end 222. In this embodiment, the second pipe section 24 is arranged to extend rearward to facilitate connection to a steam delivery pipeline (generally a flexible hose) located behind the steam outlet device 100.

[0062] Preferably, please refer to Figures 1 to 5Each of the mounting walls 41 is provided with a screw hole. A mounting plate 25 is integrally formed on the outside of the second pipe section 24. Bolts are provided on the mounting plate 25, and these bolts engage with the corresponding screw holes to screw the first mounting member 20 to the adjacent mounting wall 41. Thus, the first mounting member 20 is screwed and fixed to the bracket 40, thereby limiting its position and preventing the first pipe section 23 from rotating and loosening due to high pressure during steam transportation, which would affect its sealing performance.

[0063] Furthermore, the first mounting component 20 also includes a quick connector 26 connected to the inlet end 221. The quick connector 26 is used to connect a steam delivery pipeline, which is used to connect to the steam generating device. This quick connector 26 design makes the installation and disassembly between the first mounting component 20 and the steam delivery pipeline more convenient, and improves the compatibility and adaptability of the device.

[0064] Based on the above embodiments, please refer to the following: Figures 2 to 7 and Figure 9 The second mounting member 30 is located near the other of the two mounting walls 41 and rotatably engages with the through hole 42 on the mounting wall 41, allowing the body 10 to rotate relative to the bracket 40 during installation. This allows for convenient adjustment of the posture of the body 10 relative to the bracket 40 during assembly, facilitating installation operations.

[0065] Specifically, the rotational engagement between the second mounting member 30 and the bracket 40 is achieved through the following structure: the second mounting member 30 includes an insertion portion 31 inserted into the cavity 11 and a rotating portion 32 extending from the corresponding opening 12. The rotating portion 32 is inserted at least partially into the through hole 42 on the mounting wall 41 near the second mounting member 30. In this embodiment, during the installation of the steam export device 100, the second mounting member 30 can be first installed onto the body 10, then both can be inserted together between the two mounting walls 41 of the bracket 40, and then the rotating portion 32 can be inserted into the through hole 42. The position of the body 10 can be adjusted by rotation until it is in place, and then the first mounting member 20 can be inserted into the through hole 42 and the opening 12 on the other side. In this embodiment, through the structural engagement between the second mounting member 30 and the first mounting member 20 and the body 10, the installation operation of the body 10 is simple, reliable, and easy to implement, and it is also convenient to disassemble the first mounting member 20 and the second mounting member 30. The installation positions of the first mounting member 20 and the second mounting member 30 can be interchanged through simple operations.

[0066] Optionally, the diameter of the first mounting member 20 located inside the corresponding through hole 42 is greater than its diameter located outside the corresponding mounting wall 41, the diameter of the second mounting member 30 located inside the corresponding through hole 42 is smaller than its diameter located inside the corresponding mounting wall 41, and the rotating part 32 is housed inside the through hole 42 and flush with the outer side of the corresponding mounting wall 41.

[0067] Thus, the steam extraction device can be assembled sequentially in the order of the main body 10, the second mounting member 30, the bracket 40, and the first mounting member 20. Specifically, the second mounting member 30 can be installed on the main body 10 first, and then the assembled main body 10 can be rotated and installed on the bracket 40 from the inside of the mounting wall 41 via the second mounting member 30, after which the first mounting member 20 can be assembled. This method is simple to operate and has a reliable structure.

[0068] Optionally, the insertion portion 31 has a second annular groove 311 on its outer periphery, and the second mounting member 30 also includes a sealing ring 60 sleeved on the outer periphery of the insertion portion 31, the sealing ring 60 being engaged in the second annular groove 311. Preferably, multiple second annular grooves 311 and sealing rings 60 can be provided correspondingly to enhance the sealing performance of the second mounting member 30 to the opening 12.

[0069] Alternatively, please continue reading Figure 9 The rotating part 32 includes a pivot 321 rotatably mounted in the corresponding through hole 42, and a flange 322 disposed between the pivot 321 and the insertion part 31. The outer diameter of the flange 322 is larger than that of the insertion part 31 and the pivot 321. The end face of the flange 322 near the insertion part 31 abuts against the body 10 and rests against the outside of the opening 12. The end face of the flange 322 near the pivot 321 abuts against the inner side of the corresponding mounting wall 41. In this embodiment, through the rotational cooperation between the rotating part 32 and the bracket 40, the relative position between the body 10 and the bracket 40 can be flexibly adjusted during the installation process to ensure that the first mounting member 20 can be smoothly cooperated with the body 10. The flange 322 is clamped between the inner side of the body 10 and the mounting wall 41, which plays a role in radially limiting the body 10.

[0070] Optionally, please refer to Figure 10The main body 10 is provided with a limiting part, and the bracket 40 is provided with a limiting mating part. The limiting part and the limiting mating part cooperate to limit the rotational stroke of the main body 10 relative to the bracket 40. Specifically, the limiting part consists of two arc-shaped protrusions 14 protruding from the main body 10, which are respectively located on two mounting sides 13 and positioned behind the second mounting member 30. The limiting mating part consists of arc-shaped grooves 43 recessed on each mounting wall 41, with each arc-shaped protrusion 14 correspondingly embedded in each arc-shaped groove 43. In this embodiment, the bracket 40 is preferably made of a material with a certain degree of elasticity. When the main body 10 is embedded between the two mounting walls 41 and the second mounting member 30 is rotatably engaged with the bracket 40, the main body 10 can be rotated according to installation needs to adjust the posture of the main body 10 relative to the bracket 40. During rotation, when the arc-shaped protrusion 14 is engaged in the corresponding arc-shaped groove 43, it indicates that the main body 10 has been rotated into place, and the first mounting member 20 can continue to be installed. In this embodiment, the cooperation between the limiting part and the limiting mating part effectively restricts the rotation of the main body 10, ensuring that the main body 10 rotates to the point where the opening 12 on the other side is completely aligned with the through hole 42 on its outer side, allowing the first mounting member 20 to continue to be installed. On the one hand, this makes the structure of the main body 10 mounted on the bracket 40 simpler and more reliable, and on the other hand, it improves the installation efficiency of the steam exhaust device 100.

[0071] Optionally, the two openings 12 on the main body 10 are coaxially arranged, and when the main body 10 is fixed on the bracket 40, the main body 10 is rotatably arranged around the axis of the two openings 12. In this embodiment, through the respective installation and cooperation of the first mounting member 20 and the second mounting member 30 with the bracket 40, the main body 20 is rotatably mounted on the bracket 40 in an adjustable manner around the axis of the two openings 12. This allows the rotation angle of the main body 10 to be controlled according to the operational requirements during beverage preparation, thereby introducing steam into the beverage at the optimal angle according to the preparation requirements.

[0072] Furthermore, the limiting portion consists of a pair of protrusions on the main body, and at least one pair of grooves are provided on the two mounting walls. The protrusions cooperate with the corresponding grooves to limit the rotation angle of the main body 10 relative to the bracket 40. In this embodiment, the shapes of the protrusions and grooves are adapted to limit the rotation path of the main body 10 relative to the bracket 40, thereby more accurately limiting the rotation position of the main body 10. Furthermore, the protrusions can retract and abut against the inner side of the mounting wall 41 to achieve suspension of the main body 10 relative to the bracket 40 at any angle. Thus, the suspension of the main body's rotation position is achieved through the elastic abutment between the protrusions and the mounting wall 41, resulting in a simple and reliable structure.

[0073] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
