Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a manual automatic milk frothing component for coffee machines. Background Technology

[0002] In the capsule coffee machine industry, the steam wand is a key component for making milk-based coffee drinks (such as lattes and cappuccinos). Its main function is to heat and froth the milk by spraying high-temperature, high-pressure steam. Currently, most capsule coffee machines on the market have separate steam wand adjustment and on / off controls.

[0003] This fixed structure has significant limitations in practical use: Existing technology requires two hands to manually steam froth milk. For example, after placing the milk container, one hand needs to adjust the steam pipe, and then the other hand needs to turn on the steam valve. Alternatively, one hand might need to adjust the steam pipe before turning on the valve to create large froths. These steps cannot be completed in one go and require multiple operations, making frothing time longer and efficiency lower. Furthermore, the fixed, exposed steam pipe occupies extra space when not in use and has poor coordination with the overall design of the coffee machine, affecting the product's aesthetics. Utility Model Content

[0004] The purpose of this invention is to provide a manual automatic milk frothing component for coffee machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual automatic milk frothing component for a coffee machine, comprising:

The steam pipe 1 is fixed to the steam pipe fixing base 2, with one end extending out of the front cover of the coffee machine. A portion of the steam pipe 1 can be pulled out or retracted into the coffee machine body via the handle 5. Compared to traditional steam pipes, the steam pipe of this utility model can be extended and retracted to accommodate milk containers of different heights, and can be retracted when not in use, saving space and being aesthetically pleasing.

[0030] In an embodiment of this utility model, the steam pipe fixing seat 2 is provided with a placement groove 21, and one end of the steam pipe 1 is placed in the placement groove 21. Specifically, the end of the steam pipe 1 located in the placement groove 21 is fixedly connected to the placement groove 21, and the steam pipe 1 is moved when the steam pipe fixing shaft 2 moves.

[0031] In a specific embodiment of this utility model, the steam pipe fixing seat 2 is movable within the capsule coffee machine body. Furthermore, the steam pipe fixing seat 2 is provided with a rack 22, which is located on one side of the lower end of the steam pipe fixing seat 2. A damping gear 3 is located on the side of the steam pipe fixing seat 2 where the rack 22 is provided and meshes with the rack 22. The damping gear 3 allows the steam pipe 1 to be in any position.

[0032] In this embodiment of the invention, the locking component 4 is disposed on the steam pipe fixing seat 2. The locking component 4 is used to fix the steam pipe fixing seat 2 when the steam pipe 1 retracts to a set position. The locking component 4 includes a buckle body 41 and a hook 42. One end of the buckle body 41 is provided with an elastic groove 43, and the hook 42 is movably connected to the groove 43. Specifically, the buckle body 41 is disposed in the inner cavity of the capsule coffee machine, and the end without the groove 43 is connected to the inner cavity of the capsule coffee machine. The hook 42 is disposed at the upper end of the steam pipe fixing seat 2, for example, at the upper end of the side wall of the placement groove 21, with the connecting part of the buckle 42 facing the groove 43. When the damping gear 3 rolls to the front end of the steam pipe fixing seat 2, the hook 42 engages with the groove 43, and the position of the steam pipe fixing seat 2 remains fixed.

[0033] In an embodiment of this utility model, the steam pipe 1 includes an inner pipe 11, an upper pipe 12, and a lower pipe 13. A handle 5 is provided between the upper pipe 12 and the lower pipe 13. The inner pipe 11 is located inside the upper pipe 12 and the lower pipe 13. The inner pipe 11 is a Teflon tube. A steam nozzle 14 is provided at the bottom end of the lower pipe 13, and the inner pipe 11 is connected to the steam nozzle 14. Specifically, one end of the lower pipe 13 is provided with a threaded tube 15, and the handle 5 is sleeved on the threaded tube 15. One end of the upper pipe 12 is threadedly connected to the threaded tube 15. The upper end of the steam nozzle 14 is threaded and is threadedly connected to the lower pipe 13.

[0034] In an embodiment of this utility model, the steam pipe fixing seat 2 is generally arc-shaped, and the rack 22 is located on one side of the bottom end of the steam pipe fixing seat 2.

[0035] In this embodiment of the invention, the upper tube 12 is arc-shaped, and its curvature is equal to that of the steam pipe fixing seat 2. One end of the upper tube 12 is located in the placement groove 21. When the steam pipe fixing seat 2 moves outward, it can move the steam nozzle 14 of the steam pipe 1 downward, making it easier to insert into the milk container.

[0036] In this embodiment of the invention, a gear mounting plate 31 is provided on the outer side of the damping gear 3, and the gear mounting plate 31 is provided with screw holes. This facilitates the fixing of the damping gear 3 to other structures.

[0037] In this embodiment of the invention, a steam pipe cap 6 and a steam pipe support 7 are also included. The steam pipe cap 6 is connected to the steam pipe support 7, and a steam pipe fixing seat 2 is disposed inside the steam pipe cap 6. The steam pipe cap 6 has an arc-shaped slide 64 that is also adapted to the steam pipe fixing seat, and the steam pipe fixing seat 2 is slidably connected to the slide groove. A damping gear 3 is mounted on one side of the steam pipe cap 6 via a gear mounting plate 31. The upper end of the steam pipe cap 6 has a snap-fit ​​mounting groove 61, and a snap-fit ​​body 41 is disposed within the snap-fit ​​mounting groove 61. The steam pipe support 7 is installed inside the capsule coffee machine cavity, and an air pump 71 and a valve 72 are mounted on the steam pipe support 7. The valve 72 is used to control the gas in the steam pipe 1, and the air pump 72 is used to supply gas to the steam pipe 1. The steam pipe cap 6 also has a hook notch 62 and a slot notch 63. A rocker switch 64 is provided on the upper side of the hook notch 62, and the hook 42 is in movable contact with the rocker switch 64. The rocker switch 64 is connected to the air pump 71 and valve 72 via the coffee machine's built-in control program. When the hook 42 touches the rocker switch 64, the control program controls the air pump 71 and valve 72 to start supplying steam through the steam pipe 1. The control program of this application can be implemented by a PLC (Programmable Logic Controller). The PLC model can be a conventional model in the art (such as the Siemens S7-1200 series). Its input module is used to receive the trigger signal of the rocker switch, and its output module is used to drive the air pump contactor and the valve solenoid valve. The hardware connection method and basic I / O drive logic of the PLC described above are conventional operations for those skilled in the art and do not constitute an improvement of this application.

[0038] The working principle of this utility model is as follows: The operator holds the handle 5 and pulls the steam pipe 1 downwards. As the steam pipe 1 slides outwards, it moves the steam pipe fixing seat 2. After moving a certain distance, the hook 42 touches the anti-slip switch 64, and the steam pipe 1 automatically starts to spray steam to froth milk. After completion, the operator pulls the handle 5 upwards to make the hook 42 engage with the buckle body 41, and the steam pipe 1 returns to its original position. The entire process only requires one hand to operate, which improves the efficiency of frothing milk.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
