[0002] With the increasing popularity of the use of beverage machines such as coffee machines, the heating device of the beverage machine can generate hot water for brewing coffee, making tea, or directly providing drinking hot water. The heating device can also generate steam for foaming milk, and adding the milk foam to coffee can enrich and improve the taste of coffee. Currently, there are mainly two ways to use the steam of the beverage machine to foam milk. One is a milk frother integrated with a milk storage container, which has a high degree of automation in operation, but has a relatively complex structure and a large amount of work for cleaning and maintenance after use; the other is to use a steam rod to extend into the milk liquid and directly inject the steam, which is relatively time-consuming in operation, but has a relatively simple structure and a small amount of work for cleaning and maintenance after use.

[0003] When using the steam rod to foam milk, after the steam of the beverage machine is turned off after foaming, the head of the steam rod still stays in the milk liquid, which will cause part of the milk liquid to be sucked back into the inside of the steam rod. If this part of the milk liquid remaining inside the steam rod is not cleaned in time, it will deteriorate and produce an odor over time, affecting the hygiene and quality of foaming milk. However, currently, most steam rods are closed structures with only an air inlet and an air outlet, which is not convenient for cleaning the inside of the steam rod and affects the use of the steam rod.

[0025] Next, refer to Figures 1 - 3 Describe a steam rod of a beverage machine according to some embodiments of the present application.

[0026] The utility model provides a steam rod of a beverage machine through the following technical solutions, which includes a connecting part 1 and an extension part 2. A connecting structure is provided between the connecting part 1 and the extension part 2, and the connecting part 1 is connected or separated from the extension part 2 through the connecting structure.

[0027] Specifically, the connecting part 1 includes a first interface 3, a second interface 4 and a third interface 5 that are interconnected. The second interface 4 and the third interface 5 are arranged opposite to each other, and the first interface 3 is spaced from the second interface 4 and the third interface 5. The extension part 2 includes a fourth interface 6 and a steam outlet 7 that are interconnected and arranged opposite to each other. A first convex block 8 is provided on the outer side wall of the third interface 5, and a first clamping groove 9 is provided on the inner side wall of the fourth interface 6. Insert the third interface 5 into the fourth interface 6 and rotate it so that the first convex block 8 is clamped with the first clamping groove 9, and the connecting part 1 and the extension part can be connected. An air inlet nozzle 13 is provided at the head of the first interface 3. The air inlet nozzle 13 is used to connect to the steam valve port of the beverage machine and communicate the steam. The steam generated by the beverage machine enters the connecting part 1 through the air inlet nozzle 13 via the first interface 3, passes through the pipeline inside the connecting part 1, enters the extension part 2 through the third interface 5 and the fourth interface 6, and finally is discharged from the steam outlet 7. The steam outlet is inserted into the milk liquid during use. Therefore, after the steam is discharged from the steam outlet 7, it directly acts on the inside of the milk liquid, thus completing the production of milk foam.

[0028] A end cover 18 is provided at the second interface 4 of the connecting part 1. A second convex block 19 is provided on the outer edge of the top of the end cover 18, and a second clamping groove 20 that matches the second convex block 19 is provided on the inner side wall of the second interface 4. Place the end cover 18 into the second interface 4 and rotate it so that the second convex block 19 is clamped with the second clamping groove 20, and the end cover 18 is connected and closes the second interface 4. Thus, when the steam rod is in use, only the first interface 3 as the steam inlet and the steam outlet 7 as the steam outlet, the two open interfaces are retained, and the rest of the interfaces are in a closed state, ensuring the flow and sealing of the steam.

[0029] After use, remove the air inlet nozzle 13 from the steam valve port of the beverage machine, rotate the third interface 5 inserted into the fourth interface 6 to disengage the first convex block 8 from the first clamping groove 9, and separate the connecting part 1 and the extension part 2; rotate the end cover 18 in the second interface 4 to disengage the second convex block 19 from the second clamping groove, and take out the end cover 18 to open the second interface 4. In this way, the first interface 3, the second interface 4 and the third interface 5 of the connecting part 1 are all in an open state, and the fourth interface 6 and the steam outlet 7 of the extension part 2 are all in an open state. The inside of the connecting part 1 and the extension part 2 can be cleaned from different directions through the open interfaces. The cleaning operation is very convenient, and the cleaning effect is also very good, avoiding the situation where there are dead corners during one-way cleaning, resulting in the accumulation of milk liquid spoilage.

[0030] In order to improve the connection sealing performance of relevant interfaces, a first annular groove 10 is provided on the side wall at the bottom of the third interface 5, and a first sealing member 11 is arranged in the first annular groove 10 to enhance the sealing performance of the connection between the third interface 5 and the fourth interface 6; a second annular groove 16 is provided on the side wall of the end cover 18, and a second sealing member 17 is arranged in the second annular groove 16 to enhance the connection sealing performance of the end cover 18 to the second interface. The above-mentioned sealing members can adopt elastic sealing members such as rubber rings and silica gel rings.

[0031] In order to have good heat resistance and food hygiene for the connecting portion 1 and the extending portion 2, generally food-grade stainless steel materials are used. They have good thermal conductivity, and the surface temperature is relatively high during use, so they cannot be directly held, and heat insulation members need to be added. Specifically, a first heat insulation sleeve 12 is sleeved on the first interface 3, and the air inlet nozzle 13 at the head of the first interface 3 extends out of the first heat insulation sleeve 12, and the first heat insulation sleeve 12 does not affect the connection between the air inlet nozzle 13 and the steam valve port of the beverage machine. When the steam rod is in use, the temperature of the first interface 3 is the highest, and when the steam rod is inserted and removed on the beverage machine, the first interface 3 also needs to be frequently grasped. Therefore, the first heat insulation sleeve 12 and the first interface 3 need to have good fitting and positioning. In order to enhance the fitting and positioning between the first heat insulation sleeve 12 and the first interface 3, a positioning block 14 is provided on the outer wall of the first interface 3, and a positioning groove 15 that matches the positioning block 14 is provided on the inner wall of the first heat insulation sleeve 12. After the first heat insulation sleeve 12 is sleeved on the first interface 3, the positioning block 14 is embedded in the positioning groove 15, restricting the radial movement of the first heat insulation sleeve 12 relative to the first interface 3. A limiting structure is provided between the air inlet nozzle 13 and the first heat insulation sleeve 12. The limiting structure includes a third annular groove 21 on the outer wall of the first interface 3 located between the air inlet nozzle 13 and the first heat insulation sleeve 12, and a snap ring 22 arranged in the third annular groove 21. After the first heat insulation sleeve 12 is sleeved on the first interface 3, the snap ring 22 is clamped in the third annular groove 21, restricting the axial movement of the first heat insulation sleeve 12 relative to the first interface 3.

[0032] Similarly, a second heat insulation sleeve 23 is also sleeved on the second interface 4. The above-mentioned heat insulation sleeves can be made of elastic heat insulation materials such as rubber and silica gel.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
