[0035] In order to further understand the content, characteristics and effects of the present utility model, the following embodiments are cited and described in detail with the accompanying drawings as follows:

[0036] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the present utility model provides an automatic coffee machine, which includes a grinding device and a brewing device.

[0037] The brewing device includes a support member 1, an extraction cup 2, a driving member 3 and a moving member 4. A cavity 11 is formed inside the support member 1, and the cavity 11 communicates with the powder outlet of the grinding device. The extraction cup 2 is detachably installed on the support member 1, and the cup mouth of the extraction cup 2 faces the cavity 11. The driving member 3 is installed on the support member 1. The moving member 4 is connected to the driving member 3, and the moving member 4 can move in the cavity 11 and the extraction cup 2 under the drive of the driving member 3, so that the brewing device can be switched among a first state, a second state and a third state.

[0038] In a specific application, the automatic coffee machine further includes a controller, which is electrically connected to the grinding device and the brewing device. When the automatic coffee machine is on standby, the brewing device is in the first state (that is, the moving member 4 makes the cavity 11 not communicate with the inside of the extraction cup 2). When starting to make coffee, first, the controller controls the driving member 3 to drive the moving member 4 to move, so that the brewing device is switched to the second state (that is, the powder outlet of the grinding device, the cavity 11 and the inside of the extraction cup 2 are communicated with each other), so that the coffee powder ground by the grinding device can sequentially pass through the powder outlet of the grinding device and the cavity 11 and fall into the inside of the extraction cup 2; secondly, the controller controls the driving member 3 to continue to drive the moving member 4 to move, so that the brewing device is switched to the third state (that is, the moving member 4 extends into the inside of the extraction cup 2 under the drive of the driving member 3) to flatten the coffee powder in the extraction cup 2; finally, the controller controls the driving member 3 to continue to drive the moving member 4 to move, so that the brewing device is switched to the first state again, so as to be able to perform coffee extraction on the flattened coffee powder in the extraction cup 2.

[0039] Through the above technical solutions, the grinding, powder receiving and powder pressing actions in the coffee making process are all realized on one machine. Compared with using multiple devices to make coffee, it not only reduces the space utilization rate, but also reduces the degree of manual intervention in the making process, making it more convenient to use.

[0040] Such as Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, in some preferred embodiments, the above-mentioned moving part 4 includes a fixed sleeve 41, a moving sleeve 42, a moving block 43 and a movable sleeve 44. One end of the fixed sleeve 41 is fixedly arranged on the support part 1. The moving sleeve 42 is sleeved on the fixed sleeve 41, and the moving sleeve 42 can move relative to the fixed sleeve 41. The moving block 43 is connected to the moving sleeve 42, and a material discharging port 45 is formed between the moving block 43 and the moving sleeve 42. The movable sleeve 44 is sleeved on the moving sleeve 42 and the moving block 43, the movable sleeve 44 is connected to the driving part 3, and the movable sleeve 44 can push the moving sleeve 42 upward or push the moving block 43 downward under the drive of the driving part 3.

[0041] As Figure 2 shown, in some preferred embodiments, the above-mentioned driving part 3 includes a driving motor 31, a gear 32 and a rotating sleeve 33. The driving motor 31 is arranged on the support part 1. The gear 32 is connected to the output shaft of the driving motor 31. The rotating sleeve 33 is arranged in the cavity 11, the rotating sleeve 33 has teeth 331 on it, the teeth 331 are engaged with the gear 32, an internal thread 332 is arranged on the inner side wall of the rotating sleeve 33, an external thread 445 is arranged on the outer side wall of the movable sleeve 44, and the internal thread 332 is screwed with the external thread 445.

[0042] In specific applications, when the brewing device is switched from the first state to the second state, the driving motor 31 drives the gear 32 to rotate, the gear 32 drives the rotating sleeve 33 to rotate through the teeth 331, and the rotating sleeve 33 drives the movable sleeve 44 to move upward through the screwed internal thread 332 and external thread 445, so that the ground coffee powder can flow into the powder outlet of the grinding device, the inside of the fixed sleeve 41, the inside of the moving sleeve 42 and the material discharging port 45 in sequence and fall into the inside of the extraction cup 2; when the brewing device is switched from the second state to the third state, the driving motor 31 drives the gear 32 to rotate, the gear 32 drives the rotating sleeve 33 to rotate through the teeth 331, and the rotating sleeve 33 drives the movable sleeve 44 to move downward through the screwed internal thread 332 and external thread 445, the movable sleeve 44 pushes the moving block 43 downward so that the moving sleeve 42 moves downward relative to the fixed sleeve 41, so that the lower surfaces of the movable sleeve 44 and the moving block 43 both extend into the extraction cup 2 to flatten the coffee powder in the extraction cup 2; when the brewing device is switched from the third state to the first state, the driving motor 31 drives the gear 32 to rotate, the gear 32 drives the rotating sleeve 33 to rotate through the teeth 331, and the rotating sleeve 33 drives the movable sleeve 44 to move upward through the screwed internal thread 332 and external thread 445, the movable sleeve 44 pushes the moving sleeve 42 upward, so that the moving sleeve 42 moves upward relative to the fixed sleeve 41, and the moving sleeve 42 drives the moving block 43 to move upward, so that the lower surfaces of the movable sleeve 44 and the moving block 43 both move from inside the extraction cup 2 to inside the cavity 11.

[0043] Specifically, the upper surface of the moving block 43 has an inclined surface, and the coffee powder flowing through the moving sleeve 42 can smoothly flow down along the inclined surface, pass through the material discharge port 45 and fall into the extraction cup 2, preventing the coffee powder from accumulating on the moving block 43 and causing blockage of the material discharge port 45. Preferably, the upper surface of the moving block 43 is a conical surface. In this way, it can not only ensure the smooth flow of the coffee powder but also make the coffee powder evenly fall into the extraction cup 2.

[0044] Specifically, a first sealing groove is provided on the outer sidewall of the movable sleeve 44, and a first sealing ring is provided in the first sealing groove. When the lower surface of the movable sleeve 44 extends into the extraction cup 2, the first sealing ring abuts against the inner sidewall of the extraction cup 2 to prevent the coffee powder from flying out through the gap between the movable sleeve 44 and the extraction cup 2.

[0045] In some preferred embodiments, a convex block 421 protruding outward is provided on the outer sidewall of the above-mentioned moving sleeve 42, and the convex block 421 is in movable contact with the upper end surface of the movable sleeve 44. By providing the convex block 421 protruding outward on the outer sidewall of the moving sleeve 42, when the movable sleeve 44 moves upward, the upper end surface of the movable sleeve 44 can cooperate with the convex block 421 to ensure the stable upward movement of the moving sleeve 42. Specifically, the number of the convex blocks 421 can be multiple, and the multiple convex blocks 421 are evenly distributed on the outer sidewall of the moving sleeve 42.

[0046] In specific applications, when the brewing device is switched from the first state to the second state, the movable sleeve 44 moves upward under the drive of the drive member 3, so that the upper end surface of the movable sleeve 44 abuts against the convex block 421. At this time, the powder outlet of the grinding device, the inside of the fixed sleeve 41, the inside of the moving sleeve 42, the material discharge port 45 and the inside of the extraction cup 2 are communicated; when the brewing device is switched from the third state to the first state, the movable sleeve 44 moves upward under the drive of the drive member 3, so that the upper end surface of the movable sleeve 44 abuts against the convex block 421. As the movable sleeve 44 continuously moves upward, the movable sleeve 44 pushes the convex block 421 upward to drive the moving sleeve 42 to move upward, and the moving sleeve 42 drives the moving block 43 to move upward, so that the lower surface of the movable sleeve 44 and the lower surface of the moving block 43 both extend into the extraction cup 2, realizing the flattening of the coffee powder in the extraction cup 2.

[0047] In some preferred embodiments, a downward pressing surface 441 is provided on the inner sidewall of the above-mentioned moving sleeve 42, and the downward pressing surface 441 is in movable contact with the upper surface of the moving block 43. By providing the downward pressing surface 441 on the inner sidewall of the moving sleeve 42, when the moving sleeve 42 moves downward, the downward pressing surface 441 can cooperate with the upper surface of the moving block 43 to ensure the stable downward movement of the moving sleeve 42. Specifically, the number of the downward pressing surfaces 441 can be multiple, and the multiple downward pressing surfaces 441 are evenly distributed on the inner sidewall of the moving sleeve 42.

[0048] In specific applications, when the brewing device switches from the second state to the third state, the movable sleeve 44 moves downward under the drive of the drive member 3, so that the pressing surface 441 of the movable sleeve 44 abuts against the upper surface of the moving block 43. As the movable sleeve 44 continues to move downward, the movable sleeve 44 pushes the moving block 43 downward to drive the movable sleeve 42 to move downward, so that the lower surface of the movable sleeve 44 and the lower surface of the moving block 43 both move from inside the extraction cup 2 to inside the cavity 11.

[0049] In specific applications, a guiding strip 424 is provided on the outer sidewall of the movable sleeve 42, and a guiding groove 446 adapted to the guiding strip 424 is provided on the inner sidewall of the movable sleeve 44. The guiding strip 424 is located in the guiding groove 446 and can move in the guiding groove 446. Through the cooperation of the guiding strip 424 and the guiding groove 446, it can ensure the precise cooperative movement between the movable sleeve 44 and the movable sleeve 42.

[0050] As Figure 6 and Figure 7 shown, in some preferred embodiments, a clamping block 411 is provided on the outer sidewall of the fixed sleeve 41, and a clamping groove 422 is provided on the inner sidewall of the movable sleeve 42. When the brewing device is in the first state or the second state, the clamping block 411 is located in the clamping groove 422. In specific applications, through the cooperation of the clamping block 411 and the clamping groove 422, when the brewing device is in the first state or the second state, the movable sleeve 42 and the fixed sleeve 41 are fixedly connected, avoiding the relative movement of the movable sleeve 42 relative to the fixed sleeve 41.

[0051] Specifically, the number of the clamping blocks 411 is two, and the two clamping blocks 411 are oppositely arranged on the outer sidewall of the fixed sleeve 41. Correspondingly, the number of the clamping grooves 422 is also two, and the two clamping grooves 422 are oppositely arranged on the inner sidewall of the movable sleeve 42. Through such a design, the force can be evenly distributed when the fixed sleeve 41 and the movable sleeve 42 are connected.

[0052] As Figure 6 and Figure 7 shown, in some preferred embodiments, a first elastic portion 412 is provided on the fixed sleeve 41 or / and a second elastic portion 423 is provided on the movable sleeve 42. The clamping block 411 is provided on the outer sidewall of the first elastic portion 412, and the clamping groove 422 is provided on the inner sidewall of the second elastic portion 423. In specific applications, by providing the first elastic portion 412 on the fixed sleeve 41 or / and the second elastic portion 423 on the movable sleeve 42, when the brewing device switches from the second state to the third state, the clamping block 411 and the clamping groove 422 can be easily separated under the action of the movable sleeve 42, so that the movable sleeve 42 moves relative to the fixed sleeve 41.

[0053] Specifically, the number of both the first elastic portion 412 and the second elastic portion 423 is two, and the two first elastic portions 412 are oppositely arranged, and the two second elastic portions 423 are also oppositely arranged.

[0054] As Figure 8 and Figure 9 shown, in some preferred embodiments, a water channel 442 is provided inside the side wall of the movable sleeve 44, a water outlet hole 443 is provided on the bottom surface of the movable sleeve 44, the water channel 442 communicates with the water outlet hole 443, and the water outlet hole 443 communicates with the inside of the extraction cup 2. In specific applications, when the brewing device switches from the third state to the first state again, water can be directly injected into the extraction cup 2 through the water channel 442 and the water outlet hole 443 for coffee extraction, without moving the extraction cup 2 to the extraction device for extraction, further improving the degree of automation and making it more convenient to use.

[0055] Specifically, when the brewing device is in the first state or the third state, the movable sleeve 44 is sleeved on the moving block 43, and the lower surface of the movable sleeve 44 is coplanar with the lower surface of the moving block 43. A second sealing groove is provided on the side wall of the moving block 43, a second sealing ring is provided in the second sealing groove, and the second sealing ring abuts against the inner side wall of the movable sleeve 44. In this way, when water is injected into the extraction cup 2, water vapor will not enter the grinding device through the material outlet 45, the cavity 11 and the powder outlet of the grinding device, avoiding the influence of water vapor on the coffee beans placed in the grinding device and making them damp.

[0056] In some preferred embodiments, a bracket 5 is provided on the above-mentioned support member 1, a guide hole 51 is provided on the bracket 5, a guide rod 444 is provided on the movable sleeve 44, and the guide rod 444 can move axially in the guide hole 51 so that one end of the guide rod 444 can penetrate through the guide hole 51. In specific applications, by the cooperation of the guide hole 51 and the guide rod 444, the accuracy of the movement of the movable sleeve 44 can be guaranteed.

[0057] In some preferred embodiments, a touch switch 6 is provided on the above-mentioned bracket 5, the touch button of the touch switch 6 extends into the guide hole 51 and is in movable contact with the guide rod 444. In specific applications, the touch switch 6 is electrically connected to the controller of the automatic coffee machine. When the brewing device is in the first state or the third state, the guide rod 444 does not contact the touch button of the touch switch 6. When the brewing device is in the second state, the guide rod 444 contacts the touch button of the touch switch 6, and the controller of the automatic coffee machine controls the grinding device to work according to the contact between the guide rod 444 and the touch button of the touch switch 6.

[0058] In summary, in one or more embodiments of the present utility model, the automatic coffee machine of the present utility model drives the moving member 4 to move within the cavity 11 and the extraction cup 2 through the driving member 3, enabling the brewing device to switch among the first state, the second state, and the third state, thereby cooperating with the grinding device to automatically perform coffee grinding, powder receiving, and powder pressing during the coffee-making process, reducing manual intervention, improving the automation degree of coffee making, and making it more convenient to use.
