Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.

[0018] Figure 1 A cross-sectional view of the extraction cup 100 in a free state according to an embodiment of this application is shown. Figure 2 and Figure 3 This shows Figure 1 Enlarged views of the extraction cup 100 from different angles. See also... Figures 1 to 3As shown, the extraction cup 100 mainly consists of an extraction cup body 10, a dispensing nozzle 20, a pusher block 30, a filter screen 40, a teacup connecting rod 50, and a handle 60. The extraction cup body 10 has an extraction chamber 11 for filling with coffee powder for extraction. The dispensing nozzle 20 is fixed to the lower part of the extraction cup body 10. The dispensing nozzle 20 has a funnel-shaped receiving chamber 21 at the bottom of the extraction chamber 11, and a dispensing outlet 22 is formed at the bottom of the receiving chamber 21. The pusher block 30 is disposed in the extraction chamber 11 and can move up and down in the extraction chamber 11. A sealing ring 31 is provided on the outer periphery and / or the bottom of the pusher block 30. When the pusher block 30 is located at the bottom of the extraction chamber 11, the pusher block 30 forms a seal with the extraction chamber 11 through the sealing ring 31, thereby realizing the extraction of coffee powder in the extraction chamber 11. The pusher block 30 is also provided with a liquid guide channel 32 and a liquid guide tube 33. The liquid guide tube 33 extends from the extraction chamber 11 through the first through hole 12 at the bottom of the extraction cup body 10 into the liquid receiving chamber 21 of the outlet 20. The liquid guide channel 32 connects the liquid guide tube 33 with the extraction chamber 11 above the pusher block 30. A filter screen 40 is also fixedly provided on the upper part of the pusher block 30. In this way, the coffee liquid extracted in the extraction chamber 11 is filtered by the filter screen 40 and flows into the liquid receiving chamber 21 of the outlet 20 through the liquid guide channel 32 and the liquid guide tube 33, and then flows out from the outlet 22. Preferably, a pressure regulating valve assembly 34 can also be provided in the liquid guide tube 33. Its specific implementation is prior art and will not be described in detail in this application. Furthermore, a connecting post 35 is also provided at the bottom of the pusher block 30. The connecting post 35 extends through the second through hole 13 at the bottom of the extraction cup body 10 into the liquid receiving chamber 21 of the outlet 20. The outer end of the teacup holder 50 is rotatably connected to the outside of the liquid receiving chamber 21 of the dispensing nozzle 20, while the inner end extends through the opening 23 on the dispensing nozzle 20 into the liquid receiving chamber 21 and is rotatably and slidably connected to the connecting post 35. Thus, after coffee extraction is complete, pushing the teacup holder 50 upwards to rotate it causes the pusher block 30 to move upwards within the extraction chamber 11 (see...). Figure 4 As shown in the diagram, this pushes the compacted coffee puck upwards in the extraction chamber 11, facilitating puck cleaning. The handle 60 is attached to the outside of the extraction cup 10 for user convenience. By holding the handle 60, the user can insert or remove the extraction cup 100 from the coffee machine body.

[0019] See details Figure 2 As shown, the spring-loaded connecting rod 50 includes a V-shaped rod 51 and a connecting portion 52 formed at the inner end of the V-shaped rod 51. The outer end of the V-shaped rod 51 is rotatably connected to the outside of the liquid receiving cavity 21 of the liquid outlet 20, avoiding the extraction cavity 11, via a connecting shaft 54. The inner end of the V-shaped rod 51 extends into the liquid receiving cavity 21 through the opening 23 on the liquid outlet 20. The connecting portion 52 is rotatably and slidably connected to the lower end of the connecting post 35 at the bottom of the pusher block 30. See further details. Figure 3As shown, the lower end of the connecting column 35 has grooves 351 on opposite sides. The connecting part 52 of the spring-loaded connecting rod 50 has opposing protrusions 53 on both sides that fit into the grooves 351. The protrusions 53 can rotate within the grooves 351 while sliding along them. Thus, the spring-loaded connecting rod 50 rotates up and down around the connecting shaft 54 ​​at its outer end, causing the protrusions 53 to rotate and slide within the grooves 351, thereby acting on the connecting column 35 and causing it to move up and down. This, in turn, causes the pusher block 30 to move up and down within the extraction chamber 11. To ensure smoother movement of the pusher block 30 within the extraction chamber 11, the connecting column 35 is preferably positioned in the middle of the pusher block 30.

[0020] See also Figure 3 As shown, an elastic reset member is further provided between the pusher block 30 and the bottom of the extraction cup 10 to ensure that after the pusher block 30 is pushed upward by the spring plate connecting rod 50 and moves upward in the extraction chamber 21, it can move downward to reset and form a seal with the extraction chamber 11. See details. Figure 3 As shown, the bottom of the push block 30 has mounting posts 36 extending downward through the third through hole 14 at the bottom of the extraction cup 10 on opposite sides. A locking screw 37 is provided at the lower end of the mounting post 36, and the outer diameter of the locking screw 37 is larger than that of the mounting post 36. The elastic reset component is preferably a reset spring 38 sleeved on the mounting post 36. The upper end of the reset spring 38 abuts against the bottom of the extraction cup 10, and the lower end abuts against the locking screw 37. When the user pushes the spring plate connecting rod 50 to rotate it upward, causing the push block 30 to spring upward in the extraction chamber 11 (see...), Figure 4 As shown), the reset spring 38 is compressed. When the user releases the pressure, the spring force of the reset spring 38 can also cause the push block 30 to move downwards in the opposite direction and reset, pressing against the bottom of the extraction chamber 11, while simultaneously driving the spring plate connecting rod 50 to rotate and reset.

[0021] According to the above embodiment of this application, the extraction cup 100 is provided with a spring-loaded connecting rod 50 whose outer end is rotatably connected to the outside of the liquid receiving cavity 21 of the liquid outlet 20, and whose inner end extends through the opening 23 on the liquid outlet 20 into the liquid receiving cavity 21. It is rotatably and slidably connected to the connecting post 35 at the bottom of the push block 30. Therefore, by simply pushing the spring-loaded connecting rod 50 upwards to rotate it, the push block 30 can be moved upwards in the extraction cavity 11, thereby pushing out the powder cake from the extraction cavity 11. The powder cake cleaning operation is simple and convenient. After releasing the hand, the push block 30 and the spring-loaded connecting rod 50 automatically reset.

[0022] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
