[0002] The portafilter is an important component of a coffee machine. It holds the coffee grounds in place and controls the speed and direction of water flow to extract a delicious cup of coffee. Different types of coffee machines may have different portafilter designs. Common portafilters include those for drip coffee machines and espresso machines. To use it, place the coffee grounds in the portafilter basket, attach the portafilter to the machine, and start the extraction process.

[0003] Existing coffee brewing portafilters use threaded connections for the handle and spring clips for the portafilter, making disassembly of both the handle and portafilter quite troublesome. Furthermore, some portafilters experience a problem where hot water from the coffee machine leaks out from the connection point between the portafilter and the coffee machine during brewing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 One embodiment of this utility model is a quick-release structure for an anti-drip coffee extraction handle, including an extraction base 1, a powder bowl 2 slidably connected to the inner wall of the extraction base 1, an interface block 3 fixedly connected to the outer wall of the extraction base 1, a docking rod 4 fixedly connected to the right side of the extraction base 1, a handle 5 provided on the right side of the docking rod 4, and a first button 6 slidably connected to the top of the handle 5.

[0027] Specifically, the interface block 3 on the outer wall of the extraction seat 1 is used to connect with the coffee machine, the bottom of the portafilter 2 is equipped with a filter screen to filter the coffee liquid, and the connecting rod 4 connects with the handle 5.

[0028] Reference Figure 2 - Figure 4The inner wall of the first button 6 is provided with a first spring 9, and the lower end of the first spring 9 is provided with a limit plate 13. The two sides of the limit plate 13 are fixedly connected to the inner wall of the handle 5. The lower end of the first button 6 is slidably connected with a first limit block 12. The inner wall of the first limit block 12 is fixedly connected with a locking block 8. The two sides of the locking block 8 are slidably connected with a first fixing rod 10. The two ends of the first fixing rod 10 are fixedly connected to the inner wall of the handle 5. The outer wall of the first fixing rod 10 is provided with a second spring 11. The outer wall of the locking block 8 is slidably connected with a docking block 7. The inner wall of the locking block 8 is connected to the second spring 11. The docking block 7 is fixedly connected to the middle of the left end of the handle 5. The inner wall of the docking rod 4 has a first slot 14. The locking block 8 is engaged with the inner wall of the first slot 14.

[0029] Specifically, by pressing the first button 6, the lower end of the first button 6 presses against the first limiting block 12, causing the first limiting block 12 to move inward. The movement of the first limiting block 12 drives the locking block 8 to move inward, so that the left end of the locking block 8 slides to be flush with both sides of the docking block 7. At this time, the handle 5 can be separated from the docking rod 4 by moving the handle 5 to the right. When installing the handle 5, simply move the handle 5 to the left, and the inner wall of the docking rod 4 presses against the locking block 8, making the locking block 8 flush with both sides of the docking block 7. When the locking block 8 moves to the position of the first slot 14, under the rebound action of the second spring 11, the locking block 8 engages inside the first slot 14, thus installing the handle 5. This setting makes the installation and removal of the handle 5 simpler and more convenient.

[0030] Reference Figure 5 - Figure 7 A sealing ring 15 is provided at the top of the powder bowl 2. A fixing block 16 is fixedly connected to the outer wall of the powder bowl 2. A second slot 22 is opened on the inner wall of the extraction seat 1. The fixing block 16 is engaged with the inner wall of the second slot 22. A moving rod 17 is slidably connected to the inner wall of the second slot 22. The moving rod 17 is located at the upper end of the fixing block 16. A fourth spring 21 is provided at one end of the moving rod 17. The other end of the fourth spring 21 is connected to the inside of the extraction seat 1. A second button 18 is slidably connected to the outer wall of the extraction seat 1. A second limiting block 19 is fixedly connected to one side of the second button 18. A third spring 20 is provided at one end of the second button 18. The other end of the third spring 20 is connected to the inside of the extraction seat 1. The second button 18 is slidably connected to the inner wall of the moving rod 17.

[0031] Specifically, the sealing ring 15 at the top of the portafilter 2 can completely seal when connected to the coffee machine, preventing leakage from the side during coffee extraction. To install the portafilter 2 onto the extraction base 1, simply press the second button 18. The second button 18 compresses the third spring 20, causing the second limiting block 19 to move in the pressing direction. The second limiting block 19 presses the moving rod 17 towards the fourth spring 21. When one end of the moving rod 17 is flush with the inner wall of the second slot 22, the fixing block 16 on the outer wall of the portafilter 2 is aligned with the second slot 22 and slid downwards. After installing the portafilter 2, release the second button 18 to reset the moving rod 17, which is now locked in place at the upper end of the fixing block 16, thus restricting the portafilter 2. This structure makes the installation and removal of the portafilter 2 simple and convenient.

[0032] Working principle: By pressing the first button 6, the lower end of the first button 6 presses against the first limiting block 12, causing the first limiting block 12 to move inward. The movement of the first limiting block 12 drives the locking block 8 to move inward, so that the left end of the locking block 8 slides to be flush with both sides of the docking block 7. At this time, moving the handle 5 to the right will separate the handle 5 from the docking rod 4. When installing the handle 5, simply move the handle 5 to the left. The inner wall of the docking rod 4 presses against the locking block 8, making the locking block 8 flush with both sides of the docking block 7. When the locking block 8 moves to the position of the first slot 14, under the rebound action of the second spring 11, the locking block 8 engages inside the first slot 14, thus installing the handle 5 and sealing the top of the powder bowl 2. Ring 15 ensures a complete seal when connected to the coffee machine, preventing leakage from the side during coffee extraction. To install the portafilter 2 onto the extraction base 1, simply press the second button 18. The second button 18 compresses the third spring 20, causing the second limiting block 19 to move in the pressing direction. The second limiting block 19 then presses the moving rod 17 towards the fourth spring 21. When one end of the moving rod 17 is flush with the inner wall of the second slot 22, slide the fixing block 16 on the outer wall of the portafilter 2 downwards, aligning it with the second slot 22. After installing the portafilter 2, release the second button 18 to reset the moving rod 17, which then locks into the upper end of the fixing block 16, thus restricting the portafilter 2.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
