[0052] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. "First", "second" and similar words used in the present invention do not represent any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits the detailed description of known functions and known components.

[0054] The embodiment of the present invention provides a coffee brewing system, such as Figure 1 and Figure 2 As shown, the coffee brewing system mainly includes a support 1, a brewing cup 2, a brewing seat 3 and a reset part 4.

[0055] The brewing cup 2 has a powder receiving position relative to the bracket 1. The brewing seat 3 includes a powder receiving seat 31 and a brewing rod 32. The powder receiving seat 31 is arranged in the brewing cup 2. The outer periphery of the powder receiving seat 31 is sealed with the inner wall of the brewing cup 2. The powder receiving seat 31 cooperates with the brewing cup 2 to receive the coffee powder poured into the cup, and can be close to the brewing head 8 when the brewing cup 2 moves to squeeze the coffee powder on the powder receiving seat 31 to form a powder cake 10.

[0056] The brewing seat 3 may have a water outlet channel 33. When the coffee powder on the powder receiving seat 31 is pressed into a powder cake 10, the hot water discharged through the water outlet channel 33 can soak the entire powder cake 10, thereby forming coffee liquid.

[0057] The brewing rod 32 of the brewing seat 3 passes through the bottom of the brewing cup 2 and extends to the outside of the brewing cup 2 .

[0058] The resetting part 4 is disposed on the bracket 1 , and includes a driving member 42 and a lever 41 , wherein the driving member 42 is connected to the lever 41 .

[0059] When the brewing cup 2 is in the powder receiving position, the driving member 42 can drive the lever 41 to move relative to the bracket 1, so that the lever 41 cooperates with the brewing rod 32 and drives the powder receiving seat 31 to move toward the bottom of the brewing cup 2, so that the brewing cup 2 can receive coffee powder again.

[0060] The brewing seat 3 of the coffee brewing system of this embodiment is slidably connected to the brewing cup 2, and there is no elastic part connecting the two. When the brewing cup 2 moves to the powder receiving position, the powder receiving seat 31 can be directly moved to the bottom of the brewing cup 2 by rotating the lever 41. Compared with the traditional method of driving the powder receiving seat 31 to move by a spring, the structure of this embodiment improves the smoothness of the powder receiving seat 31 moving to the bottom of the brewing cup 2, reduces noise and vibration, and makes the movement of the powder receiving seat 31 more stable.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the brewing cup 2 has a powder pressing position relative to the support 1. The coffee brewing system further includes a driving mechanism 5 and a stopper assembly 6. The driving mechanism 5 is connected to the brewing cup 2 to drive the brewing cup 2 to move back and forth between the powder pressing position and the powder receiving position. At the same time, the brewing seat 3 moves synchronously with the brewing cup 2.

[0062] like Figure 7 As shown, in some embodiments, the driving mechanism 5 includes a screw 51, a slider 52, a push rod 54 and a driving motor 53 connected to the screw 51, the screw 51 is fixed on the bracket 1, the driving motor 53 is fixed on the bracket 1 and connected to the screw 51, the slider 52 is threadedly connected to the screw 51, the slider 52 is provided with a guide groove, the guide rod 21 on the brewing cup 2 extends into the guide groove, when the slider 52 slides along the screw 51, the guide rod 21 on the brewing cup 2 cooperates with the guide groove on the slider 52, thereby driving the brewing cup 2 to move relative to the bracket 1. The specific structure of the driving mechanism 5 belongs to the prior art and will not be described in detail.

[0063] The powder pressing position may be the position where the brewing head 8 and the powder receiving seat 31 mutually squeeze the coffee powder to form a powder cake 10. Figure 1 The powder receiving position can be the position where coffee powder is poured into the brewing cup 2, see Figure 2 shown.

[0064] like Figure 5 As shown, the stopper assembly 6 is arranged on the bracket 1, and the stopper assembly 6 includes a first block body 61 and a second block body 62 which are arranged opposite to each other.

[0065] In some embodiments, the brewing cup 2 has a first stroke and a second stroke during the movement between the powder pressing position and the powder receiving position. When the brewing cup 2 moves from the powder pressing position to the powder receiving position, the brewing cup 2 moves along the first stroke and the second stroke in sequence; when the brewing cup 2 moves from the powder receiving position to the powder pressing position, the brewing cup 2 moves along the second stroke and the first stroke in sequence.

[0066] When the brewing cup 2 moves from the powder pressing position to the powder receiving position along the first stroke, the brewing rod 32 can cooperate with the first block 61 to push the powder receiving seat 31 to move to the cup mouth of the brewing cup 2, thereby pushing the brewed powder cake 10 out of the cup; when the brewing cup 2 moves from the powder pressing position to the powder receiving position along the second stroke, the brewing rod 32 can cooperate with the second block 62 to keep the powder receiving seat 31 at the cup mouth of the brewing cup 2, thereby facilitating the scraping or removal of the powder cake 10 pushed out of the cup, and facilitating the next powder receiving.

[0067] Through the cooperation of the first block 61 and the second block 62, the powder receiving seat 31 can be moved from the bottom of the brewing cup 2 to the cup mouth during the process of the brewing cup 2 moving from the powder pressing position to the powder receiving position, so as to push out the brewed powder cake 10, so that the pushed out powder cake 10 can be scraped off during the movement of the brewing cup 2. Figure 3 shown.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the first block 61 is rotatably connected to the bracket 1, and the second block 62 is fixedly connected to the bracket 1 and abuts against the first block 61 to limit the first block 61 from rotating in the first direction.

[0069] A torsion spring may be provided between the first block 61 and the bracket 1 , and is used to apply a force to rotate the first block 61 in a first direction, so that the first block 61 can always abut against the second block 62 without being acted upon by an external force.

[0070] like Figure 5 As shown, the first block 61 has a first guide surface 63, and the second block 62 has a second guide surface 64. When the first block 61 abuts against the second block 62, the first guide surface 63 and the second guide surface 64 are coplanar, and the second guide surface 64 extends in the direction of the second stroke.

[0071] Furthermore, the brewing rod 32 on the brewing seat 3 may also have a pressing rod 33. In the process of the brewing cup 2 moving from the powder receiving position to the powder pressing position along the second stroke, the pressing rod 33 is always located on the side of the first block 61 and the second block 62 away from the brewing head 8, that is, the pressing rod 33 is located below the first block 61 and the second block 62.

[0072] When the brewing cup 2 moves along the first stroke from the powder receiving position to the powder pressing position, the brewing seat 3 moves upward with the brewing cup 2, and the pressing rod 33 on the brewing seat 3 pushes the first block 61 to rotate along the second direction and move to the top of the first block 61. At the same time, under the action of the torsion spring, the first block 61 will rotate along the first direction again, thereby abutting against the second block 62 again.

[0073] When the brewing cup 2 moves from the powder pressing position to the powder receiving position along the first stroke, the pressing rod 33 on the brewing rod 32 can abut against the first guide surface 63 and / or the second guide surface 64. Since the first block 61 or the second block 62 is fixed at this time, the first block 61 or the second block 62 pushes the powder receiving seat 31 to move to the cup mouth of the brewing cup 2, thereby ejecting the brewed powder cake 10.

[0074] When the brewing cup 2 moves from the powder pressing position to the powder receiving position along the second stroke, the pressing rod 33 on the brewing rod 32 can move along the first guide surface 63 and / or the second guide surface 64, thereby ensuring that the powder receiving seat 31 is always at the position of the cup mouth.

[0075] like Figure 6 As shown, in some embodiments, the bracket 1 has a vertical track 11 and a horizontal track 13 connected to each other, and the brewing cup 2 is slidably connected to the vertical track 11 and the horizontal track 13. The vertical track 11 forms a first stroke, and the horizontal track 13 forms a second stroke.

[0076] The first block 61 and the second block 62 in the stopper assembly 6 are arranged at intervals along the extending direction of the transverse rail 13 .

[0077] The first block 61 is opposite to the vertical track 11 and is located below the vertical track 11. The second block 62 is located below the transverse track 13. The upper surface of the first block 61 forms a first guide surface 63, and the upper surface of the second block 62 forms a second guide surface 64.

[0078] When the brewing cup 2 moves downward along the vertical track 11, the pressing rod 33 on the brewing rod 32 contacts the first guide surface 63 on the first block 61. Since the first block 61 cannot rotate downward, the first block 61 pushes the powder holder 31 to move upward relative to the brewing cup 2 to the cup mouth of the brewing cup 2, thereby pushing the powder cake 10 out.

[0079] When the brewing cup 2 moves along the transverse track 13, the pressing rod 33 on the brewing rod 32 contacts the second guide surface 64 on the second block 62. Since the first guide surface 63 and the second guide surface 64 are coplanar, the powder receiving seat 31 is always at the cup mouth of the brewing cup 2 during the movement of the brewing cup 2.

[0080] like Figure 1 , Figure 2 and Figure 6 As shown, the vertical track 11 and the horizontal track 13 on the support are relative to each other through the arc track 43. When the driving mechanism 5 drives the brewing cup 2 to move to the bottom of the vertical track 11, it can move along the arc track 43 to the horizontal track 13.

[0081] In some embodiments, the upper surface of the first block 61 has an upwardly extending guide portion 65 at one end away from the second block 62, and the guide portion 65 has an arcuate guide surface connected to the upper surface of the first block 61 on the side facing the second block 62, and the arcuate guide surface is opposite to the vertical track 11.

[0082] When the brewing cup 2 moves along the vertical track 11 to its bottom, the pressure rod 33 on the brewing seat 3 can contact the arc-shaped guide surface on the first block 61, so that under the guidance of the arc-shaped guide surface, the brewing cup 2 moves along the arc-shaped track 43 to the transverse track 13, so that the pressure rod 33 on the brewing seat 3 contacts the first guide surface 63 on the first block 61.

[0083] like Figure 1 and Figure 2 As shown, in some embodiments, the coffee brewing system further includes a scraper assembly 7, which can be disposed on the bracket 1. When the brewing cup 2 moves from the initial position to the powder receiving position, the scraper assembly 7 can scrape off the powder cake 10 on the powder receiving seat 31, thereby improving the automation of the brewing system.

[0084] The scraper assembly 7 can be slidably connected to the bracket 1, and the scraper assembly 7 can slide in the vertical direction on the bracket 1. After the scraper assembly 7 slides to a suitable position, during the movement of the brewing cup 2 along the second stroke, the scraper assembly 7 can scrape the ejected powder cake 10 into the slag receiving box 9. For example, a waist-shaped groove can be provided on the bracket 1, and the scraper assembly 7 can be slidably arranged in the waist-shaped groove.

[0085] like Figures 1 to 3 As shown, in some embodiments, the coffee brewing system may further include a residue box 9, which may be located on one side of the brewing cup 2 during its movement, and the scraper assembly 7 may scrape the powder cake 10 on the powder receiving seat 31 directly into the residue box 9, thereby collecting the powder residue.

[0086] like Figures 1 to 3 and Figure 4 As shown, in some embodiments, the reset portion 4 may be located on a side of the second block 62 away from the first block 61 , and an avoidance channel 14 is provided between the second block 62 and the reset portion 4 .

[0087] When the brewing cup 2 moves to the powder receiving position, the pressing rod 33 moves away from the second block 62 and is in the avoidance channel 14. At this time, when the lever 41 drives the powder receiving seat 31 to move toward the bottom of the brewing cup 2, the pressing rod 33 will not interfere with the second block 62.

[0088] In some embodiments, the brewing rod 32 on the brewing seat 3 may further have a pressing plate 34. The driving member 42 of the reset portion 4 may be a reset motor, and the lever 41 is connected to the motor shaft of the reset motor 42. The reset motor 42 can drive the lever 41 to rotate so that the lever 41 contacts the pressing plate 34, and then drives the powder receiving seat 31 to move toward the bottom of the brewing cup 2.

[0089] For example, Figure 4 As shown, the lever 41 can be a long plate-like structure. The first end of the lever 41 is fixedly connected to the motor shaft of the driving motor, and the second end can have a push rod. When the lever 41 rotates along the first direction, the push rod can contact the pressure plate on the brewing rod 32, thereby pushing the powder receiving seat 31 to move.

[0090] When the driving member 42 is a reset motor 42, the driving member 42 can be fixed on the bracket 1, and the bracket 1 is provided with an arc track 43. The extension direction of the arc track 43 is consistent with the swing direction of the lever 41. The lever 41 is slidably connected to the arc track 43 and can slide along the arc track 43 to contact the pressure plate.

[0091] An embodiment of the present invention further provides a coffee machine, which includes the coffee brewing system described in any one of the above embodiments.

[0092] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
