Description
Technical Field
[0001] This utility model relates to the field of coffee machines, and in particular to a milk frother for a coffee machine. Background Technology
[0002] In the field of modern beverage making equipment, coffee machines and beverage machines, as common household and commercial devices, provide people with a wide variety of beverage choices. Among them, the milk frother, as a key component for making milk-frozen beverages (such as lattes and cappuccinos), directly affects the quality of the beverage and the user experience in terms of its performance and ease of cleaning.
[0003] Many milk frothers in coffee and beverage machines currently on the market have significant structural design flaws, primarily in their difficulty to disassemble and clean, especially the internal foaming components. Existing milk frothers generally use screws to secure the top and bottom covers together. This method makes it difficult for users to manually disassemble the frother and separate the foaming chamber from the connecting tubing for thorough cleaning during routine maintenance.
[0004] During use, milk residue can remain inside the foaming chamber and tubing of a milk frother. If these areas are not thoroughly cleaned promptly and effectively, the milk residue can easily deteriorate under suitable temperature and humidity conditions. This deterioration not only produces an unpleasant odor, affecting the taste of subsequently made beverages, but more seriously, using a milk frother containing this contaminated residue to make and drink beverages may pose a potential health threat, such as causing gastrointestinal discomfort. Therefore, developing a milk frother structure that is easy to disassemble and effectively cleans the internal foaming components is crucial for improving the overall performance of beverage making equipment and enhancing the user experience.

During the process of flipping and closing the milk carton lid 3, the first inclined baffle 5 causes the elastic buckle 302 to deform towards the outside of the inner lid 2 of the milk carton, thereby allowing the elastic buckle 302 to smoothly enter the slot 202 by passing over the upper wall of the slot 202.
[0047] In some embodiments, such as Figure 5 As shown, a second inclined baffle 6 is provided on the upper inner wall of the slot 202 and / or on the elastic buckle 302. The second inclined baffle 6 is configured to allow the elastic buckle 302 to smoothly disengage from the slot 202 when the milk carton lid 3 is flipped open. In this embodiment, the second inclined baffle 6 is located on the upper inner wall of the slot 202. During the process of flipping open the milk carton lid 3, the elastic buckle 302 can smoothly disengage from the slot 202 through the second inclined baffle 6. This structure, using the design of the first inclined baffle 5 and the second inclined baffle 6, optimizes the opening and closing operation of the milk carton lid, making the installation and disassembly process smoother and improving the user's operating experience.
[0048] In some embodiments, such as Figure 3 , Figure 4 and Figure 11As shown, multiple protruding ribs 203 are arranged in a ring at intervals on the outer peripheral wall of the inner lid 2 of the milk box. The protruding ribs 203 are arranged vertically and are configured to ensure a tight fit between the inner lid 2 and the milk box 1 when the inner lid 2 is fitted inside the top of the milk box 1. This structure, through the multiple protruding ribs 203, allows the inner lid 2 and the milk box 1 to achieve a tight fit, facilitating disassembly and assembly; furthermore, the milk box 1 can communicate with the outside air through the gap between two protruding ribs 203, facilitating milk feeding and also allowing the air inlet 406 to communicate with the outside air.
[0049] In some embodiments, such as Figure 9 As shown, the foaming chamber 401 includes a steam chamber 402 and a mixing chamber 403 located on both sides. The mixing chamber 403 is a mixing chamber for milk, steam, and air. A steam nozzle 404 is formed by the contraction between the steam chamber 402 and the mixing chamber 403. The foaming chamber 401 is provided with a milk inlet 405 and an air inlet 406. The milk inlet 405 is connected to the steam nozzle 404, and the air inlet 406 is connected to the mixing chamber 403. The air inlet 406 is also connected to the milk container 1. This structure facilitates the rational flow and mixing of steam, milk, and air within the foaming chamber, promoting efficient foam generation and improving the quality and yield of milk foam.
[0050] In some embodiments, such as Figures 9 to 11 As shown, the inner lid 2 of the milk carton has a steam inlet pipe 42 and a milk frothing pipe 43 arranged along its outer periphery. A milk suction tube 44 is inserted into the lower end of the inner lid 2. The steam inlet pipe 42 is connected to the steam chamber 402, the milk frothing pipe 43 is connected to the mixing chamber 403, and the milk suction tube 44 is placed inside the milk carton 1 and connected to the milk inlet hole 405. The above layout ensures the smooth delivery of steam and milk, realizing the smooth production and output of milk froth.
[0051] In some embodiments, such as Figure 3 and Figure 9 As shown, the inner cover 2 of the milk box is provided with a connecting pipe 407 that communicates with the mixing chamber 403. The connecting pipe 407 is arranged perpendicularly to the steam inlet pipe 42. For easy cleaning, the milk foam outlet pipe 43 adopts a split structure. The milk foam outlet pipe 43 includes an L-shaped adapter pipe 431 that can be inserted into the connecting pipe 407, a connector seal 432 installed at one end of the L-shaped adapter pipe 431, and a milk foam outlet pipe 433 that can be detachably installed at the other end of the L-shaped adapter pipe 431. The connector seal 432 is a sealing ring, which helps to ensure the sealing of the connection between the L-shaped adapter pipe 431 and the connecting pipe 407. The milk foam outlet pipe 433 is detachably connected to the L-shaped adapter pipe 431 by a rotating buckle, which is convenient for disassembly and assembly.
[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 11As shown, the inner cover 2 of the milk carton has a connector 204 on one side of the steam inlet pipe 42. The connector 204 is parallel to and spaced apart from the steam inlet pipe 42. When the milk frother is installed on the coffee machine, both the steam inlet pipe 42 and the connector 204 are connected to the coffee machine. The connector 204 is used to fix the milk frother. A locking rod is provided inside the coffee machine to lock the connector 204. The steam inlet pipe 42 is used to allow steam to enter. The upper cover 3 of the milk carton has two receiving slots 304 for accommodating the connector 204 and the steam inlet pipe 42. An elastic buckle 302 is located between the two receiving slots 304. Since the upper cover 3 of the milk carton is made of plastic and is located between the two receiving slots 304, the elastic buckle 302 has a certain degree of elasticity. The slot 202 is located between the connector 204 and the steam inlet pipe 42.
