[0033] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0034] Firstly, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the present invention provides a coffee extraction cup, comprising: a cup body 1, a movable component 2, and an elastic component 3.
[0035] A liquid outlet 11 is provided at the bottom of the cup body 1. A movable component 2 is disposed inside the cup body 1 and can move up and down. The movable component 2 is provided with a drainage channel 21, which is connected to the liquid outlet 11. An elastic component 3 is disposed inside the cup body 1. One end of the elastic component 3 abuts against the inner side wall of the bottom of the cup body 1, and the other end of the elastic component 3 abuts against the movable component 2.
[0036] In practical application, after the coffee grounds are collected in the coffee extraction cup, it is placed on the coffee machine corresponding to the tamping mechanism 8. The tamping mechanism 8 tamps the coffee grounds in the cup body 1. When the tamping mechanism 8 tamps the coffee grounds, the moving part 2 moves downward under the action of the tamping mechanism 8, and the elastic part 3 is compressed. The moving part 2 applies a reverse force to the coffee grounds in the cup body 1, so that the coffee grounds are not compressed too tightly in the coffee extraction cup, thereby achieving a good extraction effect during subsequent coffee extraction. Specifically, the elastic part 3 can be a spring.
[0037] like Figure 2 As shown, in some preferred embodiments, a drain valve 4 is provided in the drain channel 21. During extraction, the drain valve 4 is closed when the pressure does not reach the predetermined pressure, and opens when the pressure reaches the predetermined pressure. In this way, the coffee powder in the cup 1 can be fully extracted, further improving the extraction effect.
[0038] Specifically, the aforementioned drain valve 4 includes a plug 41, a movable plug 42, and a resetting member 43. The plug 41 is located at the outlet of the drain channel 21, and has a through hole 411 communicating with the drain channel 21. The movable plug 42 is movably disposed within the drain channel 21 and movably abuts against the inlet of the drain channel 21. The resetting member 43 is disposed within the drain channel 21, with one end abutting against the plug 41 and the other end abutting against the movable plug 42. In practical application, when the pressure inside the cup 1 exceeds a predetermined pressure, the pressure pushes the movable plug 42 downward, forcing the resetting member 43 to compress, so that the movable plug 42 no longer blocks the inlet of the drain channel 21, thereby allowing the extracted coffee liquid to flow out sequentially through the inlet of the drain channel 21, the drain channel 21, the through hole 411, and the liquid outlet 11. Specifically, the resetting member 43 can be a spring.
[0039] like Figure 4 As shown, in some preferred embodiments, the bottom inner wall of the cup body 1 is provided with multiple diversion plates 12. In specific applications, there are two liquid outlets 11. After the extracted coffee liquid flows through the through hole 411, it can flow evenly to the two liquid outlets 11 under the action of the diversion plates 12. In addition, the diversion plates 12 can also limit the other end of the elastic member 3. Specifically, the other end of the elastic member 3 is sleeved on the multiple diversion plates 12.
[0040] like Figure 2 and Figure 3 As shown, in some preferred embodiments, the movable member 2 is provided with an umbrella-shaped filter 5, which covers the drainage channel 21, and a gap is formed between the filter 5 and the drainage channel 21. In specific applications, the filter 5 can not only filter out fine powder and impurities in coffee powder, improving the taste and quality of coffee, but also prevent coffee powder from clogging the drainage channel 21.
[0041] like Figure 3 As shown, in some preferred embodiments, the upper opening of the cup body 1 has an outwardly extending extension 13, and the extension 13 is provided with a mounting position 14, within which a fixing member is provided. In specific applications, when the coffee extraction cup is placed on a coffee machine, the extension 13 cooperates with the mounting part on the coffee machine to ensure that the upper opening of the cup body 1 precisely faces the tamping mechanism 8, and the fixing member can connect with the mounting part to achieve axial positioning of the cup body 1. Specifically, the fixing member can be a magnet.
[0042] like Figure 2As shown, in some preferred embodiments, the movable member 2 is provided with a limiting part 22, which movably abuts against the blocking part 15 on the inner sidewall of the cup body 1. In specific applications, the cooperation between the blocking part 15 and the limiting part 22 not only limits the movement distance of the movable member 2 to a certain range, but also prevents the movable member 2 from being ejected under the action of the elastic member 3.
[0043] like Figure 2 and Figure 3 As shown, in some preferred embodiments, a sealing ring 6 is fitted onto the movable part 2, and the sealing ring 6 abuts against the inner wall of the cup body 1. In specific applications, the sealing ring 6 can seal the gap between the movable part 2 and the inner wall of the cup body 1, preventing coffee powder from flowing down through the gap between the movable part 2 and the inner wall of the cup body 1 and flowing out through the liquid outlet 11, thus affecting the taste and quality of the coffee.
[0044] Secondly, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the present invention provides a coffee machine including a support frame 7 and a tamping mechanism 8, and also includes the coffee extraction cup mentioned in the first aspect. The tamping mechanism 8 is disposed on the support frame 7, and the coffee extraction cup is detachably disposed on the support frame 7. When the coffee extraction cup is disposed on the support frame 7, the upper opening of the cup body 1 faces the tamping mechanism 8.
[0045] In practical applications, by default, the coffee machine is in the first state. When tamping is required, the coffee extraction cup is placed on the support frame 7 to correspond to the tamping mechanism 8. Then, the coffee machine switches to the second state to tamp and extract the coffee powder in the cup 1.
[0046] Specifically, the aforementioned tamping mechanism 8 includes a drive motor 81, a gear ring 82, a tamping head 83, and a water inlet valve 84. The drive motor 81 is mounted on a support frame 7, and its output end is connected to a gear. The gear ring 82 is rotatably mounted on the support frame 7, and its outer side wall has external teeth that mesh with the gear. The outer side wall of the tamping head 83 has external threads, which are screwed into the internal threads of the inner side wall of the gear ring 82. The tamping head 83 has a water inlet channel 831, and the water inlet valve 84 is located within the water inlet channel 831. In practical application, the drive motor 81 generates driving force to drive the gear to rotate, which in turn drives the gear ring 82 to rotate, thereby causing the tamping head 83 to move up and down. After the tamping head 83 tamps the coffee powder in the cup 1, the water inlet valve 84 opens to extract the coffee.
[0047] Specifically, the structure and operating principle of the inlet valve 84 are the same as those of the drain valve 4, and will not be described again here.
[0048] In practical applications, the aforementioned tamping mechanism 8 is electrically connected to the coffee machine's control system. The coffee machine's control system controls the operation of the tamping mechanism 8 to achieve the effect of automated control of the coffee machine. Of course, the control system of the tamping mechanism 8 can be any of an industrial computer, PLC, or microcontroller, which will not be elaborated here.
[0049] In summary, in one or more embodiments of this utility model, the coffee extraction cup and coffee machine of this utility model, by setting a moving part and an elastic part in the cup body, enable the moving part and the elastic part to cooperate to apply a reverse force to the coffee powder during tamping, thereby preventing the coffee powder from being compressed too tightly in the coffee extraction cup, thus improving the subsequent extraction effect.
[0050] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
