Description

Technical Field

[0001] This utility model relates to the technical field of coffee machine steam maker, specifically to a steam maker device. Background Technology

[0002] As living standards improve, people's demands for a wider variety of beverage flavors are increasing, especially with the growing popularity of freshly ground coffee. Milk-based coffees, as a popular choice, are seeing an increasing diversity of milk and milk foam in their recipes. Steam wands are convenient devices that automatically emit steam with the push of a button, heating and frothing milk to produce finished products at different temperatures and foaming rates, catering to various milk-based coffee flavors and the need for different latte art designs.

[0003] Generally, coffee machines are equipped with a frother, which works by using hot steam to agitate milk, incorporating air evenly during the milk's rotation to create fine, uniform foam while heating. However, traditional temperature-controlled steam wands share the same channel between the temperature probe and the steam outlet without separation. Given the limited space inside the steam wand, the temperature probe occupies most of the space, resulting in lower steam pressure and weaker steam output from the outlet. Furthermore, the temperature probe is partially concealed within the steam wand but partially exposed; when the wand is filled with hot water or steam, it becomes inaccurate in temperature sensing, affecting overall performance, causing poor steam vaporization stability, and increasing the likelihood of clogging. Utility Model Content

[0004] The purpose of this invention is to provide a steam foaming device with a larger steam chamber and a simpler structure.

[0005] The above objectives are achieved in this way.

[0006] A steam foaming device includes an outer pipe and a steam pipe. The steam pipe is disposed inside the outer pipe. A steam nozzle is provided at the lower end of the outer pipe. A temperature sensing probe is inserted through the steam nozzle. The inner side of the steam nozzle is a steam chamber. A nozzle connector is also provided. The nozzle connector connects the outer pipe and the steam nozzle. A sealing support frame is provided inside the nozzle connector. A steam pipe and a probe wire are inserted through the sealing support frame. The steam pipe communicates with the steam chamber. The probe wire is connected to the temperature sensing probe. A sealing ring is provided between the temperature sensing probe and the steam nozzle. The sealing support frame presses down on the temperature sensing probe and the sealing ring isolates the temperature sensing probe from the outside of the steam nozzle.

[0007] The objective of this utility model can also be optimized by the following technical measures.

[0008] Preferably, the steam nozzle is provided with a steam hole, and steam enters the steam chamber through the steam pipe and is then ejected from the steam hole.

[0009] Preferably, the temperature sensing probe is provided with a flange, and when the sealing support frame presses down on the temperature sensing probe, the flange presses against the sealing ring.

[0010] Preferably, there is at least one steam hole, and the bottom of the steam hole is inclined outward.

[0011] Preferably, the outer surface of the sealing support frame is provided with a skeleton.

[0012] By adopting the above technical solution, this utility model uses a nozzle connector to connect with a steam nozzle. The space of the steam chamber is larger and simpler than that of a general sealed and heat-insulated structure. The temperature sensing probe extends outside the steam nozzle and is less affected by the steam, so it can accurately detect the temperature and effectively complete the detection function.

[0019] Combination Figure 1A steam foaming device includes an outer pipe 1, a steam pipe 2, and a nozzle connector 4. The steam pipe 2 is disposed inside the outer pipe 1, and the upper end of the outer pipe 1 is connected to a steam generator. The lower end of the outer pipe 1 is provided with a steam nozzle 5 connected by the nozzle connector 4. In this embodiment, the nozzle connector 4 is threaded to the outer pipe 1, and the steam nozzle 5 is threaded to the nozzle connector 4. A sealing support frame 7 is provided inside the nozzle connector 4, and the steam pipe 2 and a probe wire 3 pass through the sealing support frame 7. The sealing support frame 7 has a first channel 71 and a second channel 72. The steam pipe 2 passes through the first channel 71, and the probe wire 3 passes through the second channel 72. A temperature sensing probe 6 is partially disposed in the second channel 72, and the temperature sensing probe 6 and the second channel 72 are press-fitted together. The first channel 71 and the steam pipe 2 are also press-fitted together. A skeleton 73 is provided around the outer surface of the sealing support frame 7. When the sealing support frame 7 is installed in the nozzle connector 4, the skeleton 73 plays a sealing role to prevent steam from leaking into the outer pipe 1. In this embodiment, there are three skeletons 73. In some embodiments, the number of skeletons 73 can be increased or decreased as needed during production.

[0020] In order to reduce the heat transfer of steam to the outer pipe 1, both the steam pipe 2 and the probe wire 3 are installed in the center of the outer pipe 1. A heat insulation space is formed between the steam pipe 2 and the outer pipe 1. The heat insulation space can be filled with heat insulation material to reduce the heat transfer rate from the steam pipe 2 to the outer pipe 1, thereby reducing the temperature of the outer pipe 1.

[0021] The steam nozzle 5 is provided with steam holes 51. Steam enters the steam chamber through the steam pipe 2 and is then ejected from the steam holes 51. There is at least one steam hole 51, and the bottom end of the steam hole 51 is inclined outward. In some embodiments, there are three steam holes 51, which are equidistantly distributed on the surface of the steam nozzle 5.

[0022] A temperature sensing probe 6 is installed below the steam nozzle 5. The inside of the steam nozzle 5 is a steam chamber. The steam pipe 2 passes through the sealing support frame 7 and communicates with the steam chamber. The probe wire 3 is connected to the temperature sensing probe 6. The temperature sensing probe 6 has a flange 61 and a detection part 62. A sealing ring 9 is provided between the detection part 62 of the temperature sensing probe 6 and the steam nozzle 5. When the sealing support frame 7 presses down on the temperature sensing probe 6, the flange 61 presses the sealing ring 9, isolating the detection part 62 outside the steam nozzle 5.

[0023] In some other embodiments, the outer conduit 1 has at least one bend, through which both the probe wire 3 and the steam pipe 2 pass.

[0024] In some other embodiments, the nozzle connector 4 is connected to the outer pipe 1 by a telescopic snap fastener, and the steam nozzle 5 is connected to the nozzle connector 4 by a telescopic snap fastener.
