Detailed Implementation

[0050] 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.

[0051] 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.

[0052] This utility model provides a beverage making machine for preparing hot drinks. Specifically, the beverage making 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. In this embodiment, a coffee machine is used as an example for illustration.

[0053] Please see Figures 1 to 12This utility model also provides a steam export structure 100, which can be installed on the body of a beverage making machine and can be connected to a steam supply device in the machine body, so as to export high-temperature steam according to the beverage preparation requirements, so that the high-temperature steam heats the milk liquid while mixing with the milk liquid and air to form milk foam.

[0054] In this embodiment, please refer to Figures 1 to 4 The steam outlet structure 100 includes an outlet member 10 and a temperature sensing member 31. The outlet member 10 extends axially, and the temperature sensing member 31 is inserted into the outlet member 10. At least one axial end of the temperature sensing member 31 extends to the outside of the outlet member 10. A limiting structure is provided between the outlet member 10 and the temperature sensing member 31 to restrict the relative rotation of the temperature sensing member 31 relative to the outlet member 10 in the circumferential direction and its relative movement towards at least one axial end. The limiting structure includes a positioning block 32 protruding from the outer periphery of the temperature sensing member 31 and a mounting groove 102 provided on the outlet member 10. The outer contour of the positioning block 32 matches the shape of the mounting groove 102 and is accommodated in the mounting groove 102. Thus, the temperature sensing member 31 is fixedly mounted to the outlet member 10 through the cooperation of the positioning block 32 and the mounting groove 102.

[0055] Specifically, please refer to Figures 1 to 4 The steam export structure 100 includes an export member 10 and a temperature sensing component 30. The export member 10 includes an elongated export member 10 and a cover 20 installed at the lower end of the export member 10. The export member 10 forms an export channel 101 extending vertically. The upper end of the export member 10 has an inlet 132 communicating with the export channel 101 to connect to a steam supply device. The cover 20, which covers the lower end of the export channel 101, has an outlet 21 communicating with the export channel 101. In this embodiment, the cover 20 is detachably installed at the lower end of the export member 10 to facilitate frequent disassembly and cleaning, maintaining the hygiene of the steam export structure 100 and improving the quality of the finished beverage. The cover 20 can be connected to the export member 10 by snap-fit, interference fit, screw connection, or other methods.

[0056] It should be noted that in this embodiment, the axial direction refers to the length extension direction of the lead-out component, while the circumferential and radial directions are descriptive directions that match the axial direction. In a preferred embodiment, the axial direction is parallel to the vertical direction. The vertical direction refers to a direction parallel to the direction of gravity extension, or a direction with an angle of less than 45 degrees to the direction of gravity extension. The description of orientation in this embodiment applies to the state when the beverage preparation equipment is installed and operating normally, and not to the state when the beverage preparation equipment is being produced, assembled, or transported.

[0057] When the steam outlet structure 100 is in operation, the steam supplied by the steam supply device is driven to flow through the pipes inside the machine body to the outlet channel 101. Specifically, after flowing into the outlet channel 101 through the inlet 132, it flows out into the beverage from the outlet 21. It is understood that the operator needs to insert the lower end of the outlet component 10 into the beverage so that the outlet 21 is submerged in the beverage, so that the steam and beverage are fully mixed, achieving uniform heating and the preparation of rich milk foam.

[0058] In this embodiment, the steam outlet structure 100 also integrates a temperature sensing component 30, which is mounted on the outlet member 10. Specifically, the temperature sensing component 30 includes a temperature detection element 31, which passes through the outlet channel 101, with its lower end extending beyond the lower end of the outlet member 10. Specifically, a through hole 22 is provided on the cover 20, and the lower end of the temperature detection element 31 extends downward from the through hole 22 into the cover 20, thus protruding from the lower side of the cover 20. The upper end of the temperature detection element 31 is used to connect a wiring harness. Thus, the lower end of the temperature detection element 31 is submerged in the beverage to accurately detect the real-time temperature of the beverage, while the wiring harness transmits signals between the temperature sensing component 30 and the control device of the machine.

[0059] The specific structure of the temperature sensing element 31 can be configured as needed. In one embodiment, a temperature probe 301 is provided at one end of the temperature sensing element 31 extending outside the outlet member 10. The positioning block 32 and the temperature probe 301 are arranged opposite to each other at both ends of the temperature sensing element 31 along the axial direction. Further, a through hole 22 is provided on the cover 20 for the temperature probe 301 of the temperature sensing component 31 to extend out, so that the temperature probe 301 can be immersed in the beverage to accurately detect the temperature change of the beverage. Specifically, the connection and fixing positions of the cover 20 and the outlet member 10, and the connection and fixing positions of the temperature sensing component 31 and the outlet member 20 are respectively located at both ends of the outlet member 10 along the axial direction. Preferably, the temperature probe 301 and the cover 20 are fitted with a clearance, so that the temperature sensing component 31 will not be disturbed when the cover 20 is disassembled and assembled, and its internal wiring harness will not be interfered with, twisted or pulled.

[0060] Optionally, the outlet 10 has an inlet 132 for connecting to a steam supply device, and a sealing ring 34 is provided between the positioning block 32 and the mounting groove 102, with the sealing ring 34 located above the inlet 132.

[0061] In an optional embodiment, the temperature sensing element 31 primarily uses its lower end to detect the temperature of the beverage. Preferably, please refer to... Figure 6 and Figure 7The temperature sensing element 31 has a wire channel running vertically through it. A temperature probe 301 is installed at the lower end of the temperature sensing element 31. A transmission line 302 passes through the wire channel and connects to the temperature probe 301. The upper end of the transmission line 302 extends out of the wire channel and is provided with a connector 303 for connecting the wire harness. In this embodiment, the temperature sensing element 31 can be made of metal, which provides a wire channel with sufficient rigidity and is not easily deformed. The temperature probe 301 is connected to the connector 303 above through the transmission line 302 passing through the wire channel, thereby connecting the power supply and control device installed in the machine body using the connector 303. The connector 303 allows the temperature sensing element 31 to be easily assembled into the steam outlet structure 100 and then installed together on the machine body, and the wire harness connection can be quickly achieved through the connector 303, improving installation efficiency.

[0062] In this embodiment, when the operator prepares a beverage, the lower end of the outlet 10 can be inserted into the beverage to inject high-temperature steam. Simultaneously, the lower end of the temperature detection element 31 is also submerged in the beverage to obtain its real-time temperature. This allows for real-time temperature monitoring during steam injection, enabling precise control of the beverage's heating temperature and achieving optimal taste. This is particularly beneficial in the commercial coffee machine sector, improving the consistency of finished beverage products.

[0063] In this embodiment, please refer to Figure 4 and Figure 8 To ensure the secure installation of the cover 20 and prevent it from being blown away by excessive steam pressure, the cover 20 is screwed to the lower end of the guide member 10. However, during the installation and removal of the cover 20, it can easily cause the temperature sensing element 31 to rotate, disturbing its internal components and potentially causing the transmission line 302 to twist or even break, thus reducing the lifespan of the temperature sensing component 30. Therefore, in this embodiment, the temperature sensing element 31 is fixed to the guide member 10 without relative rotation. When the operator disassembles the cover 20 for cleaning, the non-rotational nature of the cover 20 largely eliminates the disturbance to the temperature sensing element 31 caused by its movement, preventing adverse effects on the electrical connection stability of the temperature sensing element 31. Especially when the cover 20 is screwed to the guide member 10, it effectively prevents the temperature sensing element 31 from rotating during the assembly of the cover 20, thus avoiding the possibility of the connecting line breaking.

[0064] Preferably, please refer to Figure 8 Multiple outlets 21 are provided, and the multiple outlets 21 are distributed at intervals on the outer periphery of the through hole 22. In this way, the multiple outlets 21 increase the steam outlet area and prevent the beverage from splashing and scattering due to excessive pressure of the steam gushing out from the outlet channel 101.

[0065] Furthermore, each outlet 21 is oriented downwards and away from the through-hole 22. This not only allows the steam to enter the beverage over a wider area and heat more evenly, but also reduces the influence of steam on the temperature sensing probe 301 at the lower end of the temperature sensing element 31, thus improving the accuracy of temperature detection.

[0066] There are various ways to install the temperature sensing element 31. Please refer to the following for optional embodiments. Figure 1 , Figure 2 and Figure 5 To minimize bending of the transmission line 302, the upper end of the guide member 10 is formed with a vertically extending mounting groove 102. The upper end of the temperature sensing element 31 extends upward from the mounting groove 102. The temperature sensing assembly 30 also includes a positioning block 32 fitted onto the upper end of the temperature sensing element 31. This positioning block 32 can be integrally formed on the outer periphery of the temperature sensing element 31, or it can be connected and fixed to the temperature sensing element 31 by fixing or welding. The positioning block 32 is accommodated in the mounting groove 102 and matches the shape of the mounting groove 102 to limit the relative movement of the temperature sensing element 31 and the guide member 10 in the circumferential direction. Specifically, the cross-section of the mounting groove 102 in the vertical direction can be designed to be polygonal, and the cross-section of the positioning block 32 in the vertical direction can be non-circular, preferably a regular or irregular polygonal or elliptical structure. When the positioning block 32 is engaged with the mounting groove 102, the assembly and fixation between the positioning block 32 and the mounting groove 102 is achieved.

[0067] In other embodiments, the mounting groove 102 for the positioning block 32 to hold can also be provided on other components that can be fixed to the body 13, only requiring the temperature sensing component 30 to be fixed relative to the body 13.

[0068] In this embodiment, the positioning block 32 and the mounting groove 102 are designed to be compatible and easy to install, thereby limiting the temperature detection element 31 in the radial and circumferential directions. After the temperature detection element 31 is assembled into place by the cooperation of the positioning block 32 and the mounting groove 102, the temperature detection element 31 will no longer rotate, thus preventing the temperature detection element 31 from twisting the transmission line 302 under the action of external force, which would cause the transmission line 302 to be damaged by twisting.

[0069] Please continue reading. Figure 6 , Figure 7 and Figure 12 To achieve a seal on the mounting hole, the temperature sensing assembly 30 also includes a sealing ring 34. The sealing ring 34 is fitted onto the temperature sensing element 31 and sandwiched between the positioning block 32 and the bottom wall of the mounting groove 102. After the positioning block 32 is installed and fixed, it limits the sealing ring 34, thereby achieving a reliable seal on the mounting hole.

[0070] The temperature sensing assembly 30 also includes a pressure ring 33, which is fitted onto the upper end of the temperature sensing element 31, allowing the transmission line 302 to extend upwards and connect to the internal wiring of the machine body. The pressure ring 33 presses against the upper side of the positioning block 32 to limit the vertical movement of the temperature sensing element 31. The pressure ring 33 is detachably mounted on the guide member 10 so that the positioning block 32 is pressed against the mounting groove 102.

[0071] There are multiple ways to connect and fix the pressure ring 33 to the guide member 10. In this embodiment, the upper side of the guide member 10 is integrally formed with an upwardly protruding boss 131. The boss 131 is recessed to form an intermittently distributed mounting groove 102 and screw hole 103. The pressure ring 33 is screwed to the screw hole 103 by bolts 40.

[0072] In this embodiment, the positioning block 32 is pressed downwards against the sealing ring 34 by the pressure ring 33, achieving a more reliable sealing effect. Furthermore, in this embodiment, when installing the temperature sensing element 31, the positioning block 32 is placed into the mounting groove 102 to limit the radial and circumferential movement of the temperature sensing element 31. Then, the pressure ring 33 is used to press the positioning block 32 downwards against the sealing ring 34, limiting the vertical movement of the temperature sensing element 31. This achieves omnidirectional limiting of the temperature sensing element 31, ensuring its secure and reliable installation on the guide member 10 while preventing rotation or torsion of the temperature sensing element 31 during installation, thereby protecting the transmission line 302 within the temperature sensing element 31 from torsion damage.

[0073] Furthermore, such as Figure 7 As shown, the pressure ring 33 also has a notch 331 on one side in the radial direction. In this way, there is no need to put the pressure ring 33 on the temperature sensing element 31, transmission line 302 and connector 303. The wire harness can be inserted into the pressure ring 33 through the notch 331 and the pressure ring 33 can be tightened with bolts 40. The operation is simple, does not easily damage the wire harness, and improves assembly efficiency.

[0074] The specific structure of the export component 10 can be designed as needed. Preferably, please refer to [reference needed]. Figure 3 and Figure 4 The outlet component 10 includes an inner tube 11 and an outer tube 12 sequentially arranged along the inner and outer rings. The temperature sensing element 31 is partially inserted into the inner tube 11, and there are gaps between the temperature sensing element 31 and the inner tube 11, and between the inner tube 11 and the outer tube 12. In this way, an annular outlet channel 101 is formed between the temperature sensing element 31 and the inner tube 11, while the gap between the inner tube 11 and the outer tube 12 serves to reduce steam temperature loss and provide insulation.

[0075] Furthermore, the outlet component 10 also includes a body 13, a first connector 14, and a second connector 15. The upper end of the outer tube 12 is connected to the body 13 via the first connector 14, and the lower end of the outer tube 12 is connected to the cover 20 via the second connector 15. The upper end of the inner tube 11 is inserted into the first connector 14, and the lower end of the inner tube 11 is inserted into the second connector 15. In this way, the inner tube 11, outer tube 12, body 13, and cover 20 are connected by the first connector 14 and the second connector 15 respectively, achieving a seal between the outlet channel 101 and the heat-insulating gap. Moreover, these arrangements also allow the inner tube 11, outer tube 12, and cover 20 to be easily disassembled and cleaned.

[0076] Preferably, please refer to Figure 10 and Figure 12 The main body 13 forms a first cavity 104 located above the inner tube 11. An inlet 132 communicating with the first cavity 104 is provided on the main body 13. The inlet 132 is located around the temperature sensing element 31 and is used to communicate with a steam supply device. In this embodiment, since the upper side of the main body 13 is occupied by the upper end of the temperature sensing element 31, the positioning block 32, the pressure ring 33, and other structures, its remaining space is limited. If the inlet 132 were also located on the upper side of the main body 13, it would result in an excessively large radial dimension of the main body 13. Therefore, in this embodiment, the inlet 132 and the upper end of the temperature sensing element 31 are located on the sides of the guide channel in different directions, making the overall structure of the guide member 10 more compact and allowing it to be designed to a smaller size.

[0077] Furthermore, please continue to refer to [the relevant sources]. Figure 11 A gap exists between the lower end of the inner tube 11 and the cover 20 to form a second cavity 105 located below the inner tube 11. The outlet 21 communicates with the second cavity 105. The cross-sectional dimensions of the first cavity 104 and / or the second cavity 105 in the vertical direction are larger than the inner dimensions of the inner tube 11. In this embodiment, the first cavity 104 forms a gas storage space, allowing steam to be pressurized and pumped into the outlet channel 101, while the second cavity 105 acts as a buffer, slowing down the speed of the steam rushing out of the outlet 21 and preventing uneven steam jetting that could cause beverages to splash and scatter.

[0078] 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.
