[0054] 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.

[0055] 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.

[0056] This utility model provides a beverage machine for preparing hot drinks. Specifically, the beverage machine can be a fully automatic coffee machine, soy milk maker, etc., with grinding and brewing functions, or a capsule coffee machine, soy milk maker, etc., that prepares beverages by mixing pre-made raw material powders.

[0058] Please see Figures 1 to 3 The steam output assembly 100 includes a body 10 and a conduit assembly 30. The body 10 is used to connect to a steam generator through a steam delivery pipeline to introduce steam into the steam output assembly 100. The conduit assembly 30 is connected and fixed to the lower part of the body 10 and is used to insert a beverage to inject steam into the beverage to prepare milk foam. Further, a cavity 11 is formed within the body 10, and an inlet and an outlet are provided communicating with the cavity 11. The inlet is used to connect to the steam generator and can be located on the periphery or upper side of the body 10, while the outlet is generally located on the lower side of the body 10. Preferably, the body 10 can be mounted and fixed in the body of the beverage machine using a bracket 80.

[0059] It should be noted that in this embodiment, the vertical direction is generally close to the direction of gravity, preferably parallel to the direction of gravity. In other embodiments, the vertical direction may also have an angle of no more than 80 degrees with gravity. Thus, the conduit assembly 30 generally extends in the vertical direction to facilitate insertion into the beverage.

[0060] In one embodiment, please refer to Figures 1 to 3The steam extraction assembly 100 includes a body 10, an outer pipe 31, and a cover 20. In one optional embodiment, the steam extraction assembly 100 further includes a first connector 50, wherein one end of the outer pipe 31 is fixed to the body 10 via the first connector 50. In another optional embodiment, the steam extraction assembly 100 further includes a second connector 60, wherein the other end of the outer pipe 31 is fixed to the cover via the second connector 50. The above two embodiments can be implemented individually or in combination.

[0061] Preferably, the steam outlet assembly further includes an inner tube 32, which is inserted inside the outer tube 31 and spaced apart from the outer tube 31 to provide heat insulation and anti-scalding function.

[0062] Furthermore, one end of the inner tube 32 is fixedly inserted into the first connector 50, and a first inner sealing ring 52 is provided between the outer periphery of the inner tube 32 and the inner periphery of the first connector 50; and / or, the other end of the inner tube 32 is fixedly inserted into the second connector 60, and a second inner sealing ring 62 is provided between the outer periphery of the inner tube 32 and the inner periphery of the second connector 60. This allows the inner tube 32 to maintain a connection with the outer tube 31 in a detachable manner through the first connector 50 and / or the second connector 60, and provides the necessary gap for heat insulation and anti-scalding. In addition, the inner tube 32 can be easily disassembled for cleaning.

[0063] In one embodiment, the conduit assembly 30 includes a cap 20, an outer tube 31, and an inner tube 32. The cap 20 is detachably mounted below the body 10 and can be positioned at the lower end of the outer tube 31 and the inner tube 32 for inserting a beverage. It requires frequent disassembly and cleaning. The cap 20 has an outlet hole 21 for injecting steam into the beverage through the outlet hole 21. The outer tube 31 connects the body 10 and the cap 20, and is preferably made of a heat-insulating, clean, and durable plastic material. The inner tube 32 is fitted inside the outer tube 31, with its upper end communicating with the cavity 11 and its lower end communicating with the outlet hole 21. It is preferably made of a flexible hose. A gap 40 exists between the outer periphery of the inner tube 32 and the outer tube 31. Preferably, the cross-section of the gap 40 is annular.

[0064] In this embodiment, the gap 40 between the inner tube 32 and the outer tube 31 forms an air insulation layer, which not only effectively reduces the temperature loss of steam during the transportation of steam in the inner tube 32, improving the utilization efficiency of steam and ensuring the taste and quality of the beverage, but also has a good heat insulation effect, effectively reducing the surface temperature of the outer tube 31 and preventing users from being burned during operation.

[0065] Based on the previous embodiment, please refer to Figures 3 to 10The steam export assembly 100 further includes a first connector 50. The upper end of the outer tube 31 is connected to the body 10 via the first connector 50. The first connector 50 has a first channel 51 extending vertically. The upper end of the first connector 50 is inserted into the outlet, and the lower end of the first connector 50 is inserted into the outer tube 31. The upper end of the inner tube 32 is inserted into the first channel 51. In this embodiment, the first connector 50 mechanically connects the body 10 and the outer tube 31, and simultaneously connects the cavity 11 and the inner circumference of the inner tube 32 to form a gas guide channel. Through the cooperation of the first connector 50 and the inner tube 32, the cavity and the gas guide channel can be effectively connected, and the gas guide channel and the gap 40 can be isolated. This design not only ensures the smooth export of steam, but also enhances the stability and sealing of the steam export assembly 100, prevents steam leakage, and improves the safety of use.

[0066] Preferably, the inner tube 32 and the first connector 50 are interference-fitted. This interference fit design, through a tight connection, further ensures the sealing of the steam outlet path, preventing steam leakage at the connection point. At the same time, while ensuring the connection strength between the inner tube 32 and the first connector 50, the inner tube 32 can be disassembled and installed by simply plugging and unplugging, which facilitates the installation, removal, cleaning and maintenance of the inner tube 32.

[0067] For details, please continue reading Figure 9 and Figure 10 The inner circumferential wall of the first channel 51 is formed with an annular first inner groove 501, and a first inner sealing ring 52 is embedded in the first inner groove 501. The inner circumference of the first inner sealing ring 52 protrudes from the inner circumferential wall of the first channel 51 and presses against the outer circumference of the inner tube 32. This design utilizes the first inner sealing ring 52 with good elasticity and plasticity to achieve an interference fit between the inner tube 32 and the first connector 50, further improving the sealing effect, preventing steam leakage along the outer circumference of the inner tube 32, and ensuring the safety and anti-scalding performance of the steam outlet assembly 100.

[0068] It is understood that during the steam transmission process, a large air pressure is generated inside the inner pipe 32, and the first connector 50 needs to be securely and reliably connected to the body 10 and the outer pipe 31. Therefore, preferably, the first connector 50 is screwed to the body 10 and / or the outer pipe 31. This screwed connection design provides a stable mechanical connection between the first connector 50 and the body 10 and the outer pipe 31, facilitating the disassembly and maintenance of the steam outlet assembly 100, and improving the overall ease of use and stability.

[0069] Please continue to refer to the following: Figure 9 and Figure 10The first connector 50 has a first upper thread 5365 on its outer periphery, and is screwed to the body 10 via the first upper thread 5365. The first connector 50 also has an annular first outer groove 502 formed on its outer periphery. The first outer groove 502 is located between the first upper thread 5365 and the upper end of the first connector 50, and a first upper sealing ring 54 is embedded therein. This design not only ensures the firmness of the threaded connection, but also further enhances the sealing performance between the cavity and the gap through the sealing ring.

[0070] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The main body 10 has a downward-facing stepped surface 12 formed inside, and the upper ends of the first connector 50 and the inner tube 32 abut against the stepped surface 12. This design utilizes the integrally formed stepped surface 12 inside the main body 10 to axially limit the first connector 50 and the inner tube 32 assembled on the main body 10. This ensures the stability of the first connector 50 and the inner tube 32, prevents loosening and displacement, and improves the reliability of the steam discharge assembly 100 when discharging high-pressure steam.

[0071] Please continue to refer to the following: Figure 13 and Figure 14 The main body 10 includes a first shell 101 and a second shell 102 arranged sequentially from top to bottom. The first shell 101 has an inlet and a first through hole on its lower side. The second shell 102 has a second through hole 103 extending vertically, with the lower end of the second through hole 103 forming an outlet. The upper end of the second shell 102 is inserted into the first through hole. A limiting block 104 protrudes from the outer periphery of the second shell 102, with the upper side of the limiting block 104 abutting against the lower side of the first shell 101. The inner peripheral wall of the second through hole 103 is formed with a stepped surface 12. In this embodiment, the main body 10 is assembled from the first shell 101 and the second shell 102. This makes the complex structure of the main body 10 easier to form and allows for disassembly and assembly of the two components of the main body 10, facilitating thorough cleaning and avoiding cleaning dead spots.

[0072] Further, please refer to Figure 4 , Figure 7 and Figure 8 The steam export assembly 100 also includes a covering 70, which is installed on the lower side of the first housing 101 and sleeved on the upper end of the outer tube 31 and the outer side of the second housing 102, making the steam export assembly 100 more aesthetically pleasing. Furthermore, the lower side of the limiting block 104 abuts against the covering 70, thus the second housing 102 is clamped between the first housing 101 and the covering 70, making the structure more stable and reliable. In addition, the covering 70 provides extra protection and insulation, further reducing the temperature drop of the steam and improving the anti-scalding effect.

[0073] Please continue to refer to section 4. Figure 9 and Figure 10 The outer periphery of the first connector 50 is also provided with a first lower thread 55, which is screwed onto the outer tube 31. The outer periphery of the first connector 50 is formed with an annular second outer groove 503, which is located between the first upper thread 5365 and the first lower thread 55, and is fitted with a first lower sealing ring 56. This embodiment, through the design of double threads and a sealing ring, not only enhances the stability of the connection but also further improves the sealing effect, preventing steam leakage.

[0074] In an optional embodiment, please continue to refer to Figure 8 , Figure 11 and Figure 12 The steam export assembly 100 also includes a second connector 60, through which the lower end of the outer tube 31 is connected to the cover 20. The second connector 60 has a second channel 61 extending vertically; its upper end is inserted into the outer tube 31, and its lower end is inserted into the cover 20. The lower end of the inner tube 32 is inserted into the second channel 61. In this embodiment, the second connector 60 mechanically connects the cover 20 and the outer tube 31, and simultaneously connects the cavity 11 and the inner circumference of the inner tube 32 to form a gas guide channel. Through the cooperation of the second connector 60 and the inner tube 32, the connection between the export hole 21 and the gas guide channel can be effectively achieved, as well as the isolation between the gas guide channel and the gap 40. This design not only ensures smooth steam export but also enhances the stability and sealing of the steam export assembly 100, preventing steam leakage and improving safety during use.

[0075] Preferably, the inner tube 32 and the second connector 60 are interference-fitted. The interference fit ensures a tight connection between the inner tube 32 and the second connector 60, further ensuring the sealing of the steam outlet path and preventing steam leakage at the connection. At the same time, while ensuring the connection strength between the inner tube 32 and the second connector 60, the inner tube 32 can be disassembled and installed by simply plugging and unplugging, which facilitates the installation, removal, cleaning and maintenance of the inner tube 32.

[0076] Optionally, please refer to Figure 5 , Figure 11 and Figure 12 The inner circumferential wall of the second channel 61 is formed with an annular second inner groove 601, and a second inner sealing ring 62 is embedded in the second inner groove 601. The inner circumference of the second inner sealing ring 62 protrudes from the inner circumferential wall of the second channel 61 and presses against the outer circumference of the inner tube 32. This design utilizes the second inner sealing ring 62 with good elasticity and plasticity to achieve an interference fit between the inner tube 32 and the second connector 60, further improving the sealing effect, preventing steam leakage along the outer circumference of the inner tube 32, and ensuring the safety and anti-scalding performance of the steam outlet assembly 100.

[0077] It is understood that during the steam transmission process, a large air pressure is generated inside the inner pipe 32, and the first connector 50 needs to be securely and reliably connected to the cover 20 and the outer pipe 31. Therefore, preferably, the second connector 60 is screwed to the cover 20 and / or the outer pipe 31. In this embodiment, the screwed connection design provides a stable mechanical connection between the second connector 60 and the cover 20 and the outer pipe 31, facilitating the disassembly and maintenance of the steam outlet assembly 100, and improving the overall ease of use and stability.

[0078] Furthermore, the outer periphery of the second connector 60 is provided with a second lower thread 63, which is screwed onto the cover 20. The outer periphery of the second connector 60 is formed with an annular third outer groove 602, which is located between the second lower thread 63 and the lower end of the second connector 60, and is fitted with a second lower sealing ring 64. This design not only ensures the firmness of the threaded connection, but also further enhances the sealing performance between the cavity and the gap through the sealing ring, preventing steam leakage.

[0079] Optionally, the outer periphery of the second connector 60 is further provided with a second upper thread, which is screwed onto the outer tube 31. The outer periphery of the second connector 60 is formed with an annular fourth outer groove 603, which is located between the second upper thread and the second lower thread 63, and a second upper sealing ring 66 is embedded therein.
