Detailed Implementation

[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 machine for preparing hot drinks. Specifically, the beverage preparation 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.

[0051] Please see Figures 1 to 11This utility model also provides a steam guide 100, which can be installed on the body of a beverage preparation 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.

[0052] Specifically, please refer to Figures 1 to 3 The steam guide 100 includes a conduit assembly 10 and a temperature sensing assembly 20. The conduit assembly 10 extends axially and has an outlet channel 11 that extends through it. Preferably, the outlet channel 11 extends vertically in the conduit assembly 10. The upper end of the conduit assembly 10 has an inlet 12 that connects to the outlet channel 11 and is used to connect to a steam supply device. The lower end of the conduit assembly 10 has an outlet 13 that connects to the outlet channel 11.

[0053] It should be noted that in this embodiment, the axial direction refers to the length extension direction of the conduit assembly 10, while the circumferential and radial directions are descriptive directions adapted to the axial direction. Preferably, the axial direction extends in 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 machine is installed and operating normally, but not to the state when the beverage preparation machine is being produced, assembled, or transported.

[0054] When the steam guide component 100 is working, the steam supplied by the steam supply device is driven to flow through the pipes inside the machine body to the outlet channel 11. Specifically, after flowing into the outlet channel 11 through the inlet 12, it flows out into the beverage from the outlet 13. It is understood that the operator needs to insert the lower end of the conduit assembly 10 into the beverage so that the outlet 13 is submerged in the beverage, so that the steam and beverage are fully mixed to achieve uniform heating and the preparation of rich milk foam.

[0055] In this embodiment, the steam guide 100 also integrates a temperature sensing component 20, which is mounted on the conduit assembly 10. Specifically, the temperature sensing component 20 includes a temperature sensing rod 21. The temperature sensing rod 21 is axially inserted into the outlet channel 11 and abuts against the conduit assembly 10 in the insertion direction, thereby limiting the temperature sensing rod 21 relative to the conduit assembly 10 in the insertion direction.

[0056] Optionally, the steam guide 100 also includes a pressure member 24, which is mounted on the conduit assembly 10 and presses against the temperature sensing rod 21 to limit the movement of the temperature sensing rod 21 relative to the conduit assembly 10 in a direction opposite to the insertion direction.

[0057] Please continue reading. Figure 1Preferably, the conduit assembly 10 has a fixed end 14 and a free end 15 that can rotate around the fixed end 14. This allows the conduit assembly 10 to be rotated to a suitable angle as needed during beverage preparation to facilitate heating of the beverage. The temperature sensing rod 21 is inserted into the conduit assembly 10 along the insertion direction from the fixed end 14 toward the free end 15.

[0058] Further, please refer to Figure 7 and Figure 8 The conduit assembly 10 has a mounting groove 30, and the temperature sensing rod 21 has a radially protruding positioning member 22, which is at least partially received within the mounting groove 30. Thus, the radial positioning of the temperature sensing rod 21 can be achieved by utilizing the position between the positioning member 22 and the mounting groove 30. Preferably, the mounting groove 30 and the positioning member 22 have a compatible shape, such as an irregular ellipse or polygon, to achieve circumferential positioning between the temperature sensing rod 21 and the conduit assembly 10.

[0059] Based on the above embodiments, please refer to Figure 5 An inlet 12 for connecting to a steam supply device is formed on the conduit assembly 10, and the angle between the extending direction of the inlet 12 and the outlet channel 11 is greater than or equal to 30 degrees and less than or equal to 150 degrees. This allows steam to smoothly enter the outlet channel 11. Preferably, the mounting groove 30 is located above the inlet 12 to reduce leakage of steam or condensate from the mounting groove 30.

[0060] Preferably, the pressure member 24 covers the mounting groove 30 and has a first through hole 241 through which the temperature detection rod 21 passes upward, so that the transmission line 213 can be led out from the top of the first through hole. In this way, the transmission line 213 and the conveying pipeline for guiding steam are connected to the conduit assembly 10 from different directions, the structural arrangement is more reasonable, and the two are avoided from interfering with each other.

[0061] Temperature sensing rod 21 passes through outlet channel 11, with its lower end extending to the lower end of conduit assembly 10, and its upper end used for connecting wiring harness. Thus, the lower end of temperature sensing rod 21 is submerged in the beverage to accurately detect its real-time temperature, while the connecting wiring harness enables signal transmission between temperature sensing assembly 20 and the control device of the machine.

[0062] In this embodiment, when the operator prepares a beverage, the lower end of the conduit assembly 10 can be inserted into the beverage to inject high-temperature steam. Simultaneously, the lower end of the temperature detection rod 21 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] The specific structure of the temperature sensing rod 21 can be configured as needed; it primarily uses its lower end to detect the temperature of the beverage. For optional implementation methods, please refer to... Figure 6 and Figure 7 The temperature detection rod 21 includes a pipe wall 211 with a wire channel running vertically through it, a temperature sensor 212 installed at the lower end of the pipe wall 211, and a transmission line 213 passing through the wire channel and connected to the temperature sensor 212. The upper end of the transmission line 213 extends out of the wire channel and is provided with a connector 214 for connecting a wire harness. In this embodiment, the pipe wall 211 can be made of metal, providing a wire channel with sufficient rigidity and resistance to deformation. The temperature sensor 212 is installed at the lower end of the pipe wall 211 and is connected to the connector 214 above the pipe wall 211 via the transmission line 213 passing through the wire channel. The connector 214 is used to connect the power supply and control device wires installed inside the machine body. The connector 214 allows the temperature detection rod 21 to be easily assembled onto the steam guide 100 and then installed together on the machine body, and the wire harness connection is quickly achieved through the connector 214, improving installation efficiency.

[0064] Preferably, the lower end of the temperature sensing rod 21 extends downwards out of the conduit assembly 10. This ensures, on the one hand, that the temperature sensing probe 212 is completely submerged in the beverage, allowing the temperature sensing rod 21 to more accurately detect the beverage temperature. On the other hand, it increases the distance between the temperature sensing probe 212 and the steam outlet 13, preventing the steam from affecting the detection accuracy.

[0065] There are various ways to install the temperature sensing rod 21. In the preferred embodiment, please refer to the following reference. Figure 1 , Figure 2 and Figure 8 In order to minimize the bending of the transmission line 213, a mounting hole 31 is provided on the upper side of the conduit assembly 10, and the upper end of the temperature detection rod 21 extends out of the conduit assembly 10 through the mounting hole 31.

[0066] In a preferred embodiment, to fix the temperature sensing rod 21, the upper end of the conduit assembly 10 is formed with an open mounting groove 30, and a mounting hole 31 is formed on the bottom wall of the mounting groove 30. The temperature sensing assembly 20 also includes a positioning member 22 sleeved on the upper end of the temperature sensing rod 21. The positioning member 22 can be integrally formed with the tube wall 211 of the temperature sensing rod 21, or it can be connected and fixed to the tube wall 211 by fixing or welding. The positioning member 22 is housed in the mounting groove 30 and is assembled in the mounting groove 30 in a manner that prevents relative rotation. In this way, when the temperature sensing rod 21 is assembled in place by the cooperation of the positioning member 22 and the mounting groove 30, the temperature sensing rod 21 will no longer rotate, avoiding the temperature sensing rod 21 from twisting the transmission line 213 under the action of external force, which would cause the transmission line 213 to be damaged by twisting.

[0067] Please see Figures 5 to 7 To achieve a seal on the mounting hole 31, the temperature sensing assembly 20 also includes a sealing ring 23. The sealing ring 23 is fitted onto the temperature sensing rod 21 and sandwiched between the positioning member 22 and the bottom wall of the mounting groove 30. After the positioning member 22 is installed and fixed, it limits the sealing ring 23, thereby achieving a reliable seal on the mounting hole 31.

[0068] Preferably, please refer to the following: Figure 8 The upper end of the conduit assembly 10 is also formed with a screw hole 32, which is located on the radial side of the mounting groove 30. The temperature sensing assembly 20 also includes a pressure member 24, one end of which presses against the upper side of the positioning member 22, and the other end of which is screwed to the conduit assembly 10 through the screw hole 32. In this embodiment, the pressure member 24 presses the positioning member 22 downward to fit tightly against the sealing ring 23, achieving a more reliable sealing effect. In this embodiment, when installing the temperature detection rod 21, the positioning member 22 is placed into the mounting groove 30 to limit the temperature detection rod 21 radially and circumferentially. Then, the pressure member 24 is used to press the positioning member 22 downward to fit tightly against the sealing ring 23, thereby limiting the temperature detection rod 21 vertically. In this way, the temperature detection rod 21 is limited in all directions, so that it is firmly and reliably installed on the conduit assembly 10. At the same time, it can also prevent the temperature detection rod 21 itself from rotating or twisting during the installation process, thereby protecting the transmission line 213 in the temperature detection rod 21 from being damaged by twisting.

[0069] Furthermore, the end of the clamping member 24 that presses against the positioning member 22 is provided with a first through hole 241, and the upper end of the temperature sensing rod 21 passes through the first through hole 241. The clamping member 24 is also provided with a notch 242, which connects to the first through hole 241. In this way, there is no need to fit the clamping member 24 onto the transmission line 213 and the connector 214 of the temperature sensing rod 21. The wire harness can be inserted into the first through hole 241 through the notch 242, and the clamping member 24 can be assembled. The operation is simple, the wire harness is not easily damaged, and the assembly efficiency is improved.

[0070] It is understood that in this embodiment, since the upper side of the conduit assembly 10 is occupied by the upper end of the temperature detection rod 21, the positioning member 22, the pressure member 24, and other structures, the remaining space is not much. If the inlet 12 is also located on the upper side of the conduit assembly 10, it will cause the radial dimension of the conduit assembly 10 to be too large. Therefore, in this embodiment, please refer to... Figure 5 and Figure 8 The inlet 12 is located on the periphery of the outlet channel 11. Thus, in this embodiment, the inlet 12 and the upper end of the temperature detection rod 21 are arranged on the sides of the guide channel in different directions, making the overall structure of the conduit assembly 10 more compact and allowing it to be designed to a smaller size.

[0071] The specific structure of the catheter assembly 10 can be designed as needed. Preferably, please refer to [reference needed]. Figure 1 and Figure 4 The conduit assembly 10 includes a body 40, a sleeve 41, and a cover 42 arranged sequentially from top to bottom. An inlet 12 and a mounting hole 31 are located on the body 40. The sleeve 41 extends vertically. The cover 42 is detachably mounted on the lower end of the sleeve 41 and has an outlet 13. A second through hole 421 is also provided on the cover 42. A temperature sensing rod 21 passes through the sleeve 41, with its lower end extending downwards from the second through hole 421 onto the lower side of the cover 42. In this embodiment, the cover 42 and the sleeve 41 are separate and detachably mounted, allowing for frequent disassembly and cleaning, thus maintaining the cleanliness of the steam guide 100 even when frequently immersed in beverages.

[0072] Preferably, please refer to Figure 4 and Figure 10 The outlet 13 is oriented downwards and away from the second through-hole 421. This allows the steam to enter the beverage over a wider area, resulting in more uniform heating. It also reduces the influence of steam on the temperature sensing probe 212 at the lower end of the temperature sensing rod 21, thus improving the accuracy of temperature detection.

[0073] There are various ways to install the steam guide 100 onto the machine body. In this embodiment, the steam guide 100 also includes a bracket 50. The bracket 50 includes two mounting sidewalls 51 arranged opposite each other in the transverse direction, and two fixing walls 52 extending laterally from the rear edge of each mounting sidewall 51. The two sides of the main body 40 are correspondingly connected and fixed to the two mounting sidewalls 51. Each fixing wall 52 is provided with a mounting bolt 521 for connecting to the body of the beverage preparation machine. In this embodiment, the steam guide 100 is installed on the machine body using the bracket 50. Specifically, the main body 40 is clamped in the two mounting sidewalls 51, and the connection and fixation between the steam guide 100 and the machine body are achieved by the two fixing walls 52. The assembly is simple and the structure is reliable.

[0074] To facilitate vertical positioning of the steam guide component 100 during assembly, the bracket 50 preferably includes a mounting base wall 53 extending between the bottom edges of the two mounting side walls 51. The mounting base wall 53 has a mounting channel 531 through which the body 40 or sleeve 41 passes. This allows for convenient positioning and installation during assembly by utilizing the abutment between the mounting base wall 53 and the machine body. Furthermore, the mounting base wall 53 increases the strength and rigidity of the bracket 50, making the overall structure of the steam guide component 100 more stable and reliable.

[0075] 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.
