Description

A fully automatic coffee brewing device Technical Field

[0001] This invention relates to the field of coffee machine technology, and in particular to a fully automatic coffee brewing device. Background Technology

[0002] Currently, fully automatic coffee brewing devices on the market, such as the coffee brewing device disclosed in Chinese Patent No. CN106859344B, involve the brewing chamber receiving the coffee powder vertically and then rotating at a certain angle to enter the tamping and brewing track during the coffee powder receiving, tamping, and brewing process. The vertical reception of the coffee powder in the brewing chamber prevents the coffee powder from accumulating on one side. However, during the tamping and brewing process, due to the tilt of the brewing chamber, the coffee powder inside the chamber will accumulate to one side under the influence of gravity. This results in uneven stress on the coffee puck during the tamping process, leading to over-extraction on one side due to coffee powder accumulation and under-extraction on the other side due to insufficient coffee powder, ultimately affecting the coffee extraction effect. Summary of the Invention

[0003] This invention provides a fully automatic coffee brewing device that can prevent uneven tamping of coffee powder and ensure uniform brewing.

[0004] To address the aforementioned technical problems, embodiments of the present invention provide a fully automatic coffee brewing device, comprising:

[0005] The body has an internal sliding rail assembly;

[0006] A coffee grinder is located inside the machine body;

[0007] The brewing unit is located inside the machine body.

[0008] The drive mechanism is located inside the machine body;

[0009] A transmission mechanism is located inside the machine body and connected to the drive mechanism so as to be driven by the drive mechanism;

[0010] A brewing cup, located inside the machine body and below the grinder, is used to receive coffee powder. The direction of coffee powder output is perpendicular to the plane of the rim of the brewing cup. The brewing cup is also connected to the transmission mechanism and the slide rail assembly. When the drive mechanism drives the transmission mechanism to run, the transmission mechanism drives the brewing cup to move along the slide rail assembly, so that the brewing cup moves to below the brewer assembly and reciprocates in the direction of approaching and moving away from the brewer assembly, so that the brewer assembly completes the tamping of the coffee powder in the brewing cup in the direction perpendicular to the plane of the rim.

[0011] In one embodiment, when the drive mechanism drives the transmission mechanism to run, the transmission mechanism drives the brewing cup to move horizontally from a first position to a second position along the slide rail assembly, and at the second position drives the brewing cup to reciprocate vertically along the slide rail assembly. The first position is located below the grinder, and the second position is located below the brewer assembly.

[0012] In one embodiment, the brewing cup is connected to a guide component, the end of which is confined within the slide rail component and is movable along the slide rail component, thereby driving the brewing cup to move along the slide rail component.

[0013] In one embodiment, the transmission mechanism includes:

[0014] The first transmission component is arranged vertically and connected to the drive mechanism;

[0015] The second transmission component is arranged vertically and connected to the first transmission component;

[0016] The push rod has one end connected to the guide assembly and the other end connected to the second transmission assembly. When the drive mechanism drives the first transmission assembly, the first transmission assembly synchronously drives the second transmission assembly. When the second transmission assembly moves, it drives the guide assembly to move along the slide rail assembly through the push rod.

[0017] In one embodiment, the first transmission component includes:

[0018] The first transmission rod is arranged vertically and connected to the drive mechanism;

[0019] A first transmission component is disposed on the first transmission rod and is used to move up and down along the first transmission component under the drive of the first transmission rod. The first transmission component is connected to the second transmission assembly.

[0020] In one embodiment, the second transmission assembly includes:

[0021] The second transmission rod is set in the vertical direction;

[0022] The second transmission component is disposed on the second transmission rod and connected to the first transmission assembly, so as to move along the second transmission rod under the drive of the first transmission component.

[0023] In one embodiment, the first transmission rod is a screw, and the first transmission component is a screw sleeve;

[0024] The drive mechanism includes a motor and a gearbox, and the first transmission rod is connected to the gearbox.

[0025] In one embodiment, the push rod is formed by opening a strip-shaped hole along its length on a strip plate. The strip-shaped hole penetrates the strip plate. One end of the push rod is sleeved with the end of the guide assembly that extends into the slide rail assembly through the strip-shaped hole. The end of the slide rail assembly can move along the strip-shaped hole. When the second transmission assembly drives the push rod to move, the push rod drives the end of the guide assembly to move along the slide rail assembly and the strip-shaped hole simultaneously.

[0026] In one embodiment, the slide rail assembly includes two sets of slide rails disposed opposite to each other within the machine body. Each set of slide rails includes a first slide rail disposed horizontally and a second slide rail disposed vertically. The brewing cup is connected to both sets of slide rails and can move along them.

[0027] In one embodiment, the system further includes a Hall element, a water supply assembly connected to the brewing cup, a pusher mechanism with one end extending into the brewing cup to support coffee grounds and capable of moving up and down along the cup wall, and a control system. The control system is connected to the grinder, the water supply assembly, and the pusher mechanism to control the grinder to grind coffee grounds, the water supply assembly to supply water, and to control the pusher mechanism to move and remove the coffee puck after brewing. The control system is also connected to the Hall element and the drive mechanism to start the drive mechanism and to regulate the operation of the drive mechanism based on the kinetic energy output by the drive mechanism sensed by the Hall element.

[0028] Based on the disclosure of the above embodiments, it can be understood that the beneficial effects of the embodiments of the present invention include that by setting a driving mechanism, a transmission mechanism and a slide rail assembly in the device, the brewing cup can be moved in the device through each mechanism and assembly, so that the brewing cup can not only vertically receive the coffee powder, but also vertically press the coffee powder in the brewing cup, ensuring that the coffee powder is pressed evenly, thereby making the coffee powder brewed evenly during brewing and achieving a better coffee extraction effect.

[0047] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in still another embodiment,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0048] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0049] As shown in Figures 1, 2, and 3, an embodiment of the present invention provides a fully automatic coffee brewing device, comprising:

[0050] The main body 1 has a slide rail assembly 7 inside;

[0051] The grinder 2 is located inside the machine body 1;

[0052] The brewing unit 3 is located inside the body 1.

[0053] The drive mechanism 4 is located inside the body 1;

[0054] The transmission mechanism 5 is located inside the body 1 and is connected to the drive mechanism 4 so as to be driven by the drive mechanism 4;

[0055] The brewing cup 6 is located inside the machine body 1 and below the grinder 2. It is used to receive coffee powder. The direction of coffee powder discharge is perpendicular to the plane of the rim of the brewing cup 6. The brewing cup 6 is also connected to the transmission mechanism 5 and the slide rail assembly 7. When the drive mechanism 4 drives the transmission mechanism 5 to run, the transmission mechanism 5 drives the brewing cup 6 to move along the slide rail assembly 7, so that the brewing cup 6 moves to the bottom of the brewer assembly 3 and reciprocates in the direction of approaching and moving away from the brewer assembly 3, so that the brewer assembly 3 completes the tamping of coffee powder in the brewing cup 6 in the direction perpendicular to the plane of the rim.

[0056] In this embodiment, the transmission mechanism 5 is connected to the brewing cup 6, and the brewing cup 6 is also connected to the slide rail assembly 7 and can move along the slide rail assembly 7. In this embodiment, the initial position, or default position, of the brewing cup 6 is below the grinder 2 to facilitate receiving coffee powder. After the powder is collected, the drive mechanism 4 operates, driving the transmission mechanism 5, which moves the brewing cup 6 along the slide rail assembly 7 to below the brewer assembly 3, and reciprocates in the direction of approaching and moving away from the brewer assembly 3, causing the brewer assembly 3 to extend into and out of the brewing cup 6, thereby completing the tamping operation. After that, the coffee extraction operation can be carried out.

[0057] After the coffee extraction is complete, the drive mechanism 4 can also drive the transmission mechanism 5, which in turn drives the brewing cup 6 to move in the opposite direction along the slide rail assembly 7, thereby resetting it to its initial position and preparing it for the next coffee brewing.

[0058] As can be seen from the above embodiments, the overall design of the device in this embodiment is simple. By simply setting a drive mechanism 4, a transmission mechanism 5, and a slide rail assembly 7 within the device, the brewing cup 6 can be moved within the device through these mechanisms and components. This allows the brewing cup 6 to not only vertically receive the coffee powder but also vertically tamp the coffee powder within it, ensuring uniform pressing of the coffee puck. This results in even brewing and a better coffee extraction effect. Furthermore, because the coffee puck is pressed evenly, there is no issue of coffee powder accumulating at the bottom edge of the brewing cup 6 due to uneven pressing, such as when the cup 6 is tilted. This prevents the coffee powder from being difficult to clean, contaminating the brewing environment, and affecting the taste of the subsequent coffee.

[0059] Furthermore, in this embodiment, when the driving mechanism 4 drives the transmission mechanism 5, the transmission mechanism 5 moves the brewing cup 6 horizontally from the first position to the second position along the slide rail assembly 7, and at the second position, it moves the brewing cup 6 back and forth vertically along the slide rail assembly 7. The first position is located below the grinder 2, and the second position is located below the brewer assembly 3. In this embodiment, the brewing cup 6 moves horizontally between the first and second positions. When the brewing cup 6 is in the second position, it is controlled to move up and down vertically. During the movement of the brewing cup 6, the plane where the rim of the brewing cup 6 is located is always parallel to the horizontal plane, that is, the rim of the brewing cup 6 always remains horizontal, so that the coffee powder can be evenly distributed at the bottom of the cup, whether tamping or dispensing the coffee.

[0060] In this embodiment, a guide assembly is connected to the brewing cup 6. The specific structure of the guide assembly is not limited; for example, it can be two connectors respectively connected to the brewing cup 6, or two shafts respectively connected to the brewing cup 6, etc. The end of the guide assembly is confined within the slide rail assembly 7 and can move along the slide rail assembly 7. The transmission mechanism 5 is connected to the guide assembly, thereby driving the brewing cup 6 to move along the slide rail assembly 7.

[0061] Specifically, as shown in Figures 2 and 3, the transmission mechanism 5 includes:

[0062] The first transmission component is arranged vertically and connected to the drive mechanism 4;

[0063] The second transmission component is arranged vertically and connected to the first transmission component;

[0064] The push rod 12 is connected to the guide assembly at one end and to the second transmission assembly at the other end. When the drive mechanism 4 drives the first transmission assembly, the first transmission assembly synchronously drives the second transmission assembly. When the second transmission assembly moves, it drives the guide assembly to move along the slide rail assembly 7 through the push rod 12.

[0065] That is, the drive mechanism 4 transmits kinetic energy to the second transmission component through the first transmission component, and then the second transmission component transmits the kinetic energy to the guide component through the push rod 12. Finally, the guide component transmits the kinetic energy to the brewing cup 6, which drives the brewing cup 6 to move.

[0066] In this embodiment, the first transmission component includes:

[0067] The first transmission rod 8 is arranged vertically and is connected to the drive mechanism 4;

[0068] The first transmission member 9 is disposed on the first transmission rod 8 and is used to move up and down along the first transmission member 9 under the drive of the first transmission rod 8.

[0069] The second transmission assembly includes:

[0070] The second transmission rod 10 is arranged in a vertical direction, that is, parallel to the first transmission rod;

[0071] The second transmission member 11 is disposed on the second transmission rod 10 and connected to the first transmission member 9, so as to move along the second transmission rod 10 under the drive of the first transmission member 9.

[0072] In one application embodiment, the first transmission rod 8 is a screw with a stop fixed to its top, and the first transmission component 9 is a threaded sleeve. When the screw rotates, it can drive the threaded sleeve to move up and down along the screw. The stop is used to limit the threaded sleeve and prevent it from moving out of the screw. The drive mechanism 4 includes a motor and a gearbox 15, and the top end of the first transmission rod is connected to the gearbox 15.

[0073] Referring to Figure 3, in this embodiment, the push rod 12 is formed by creating a strip-shaped hole along its length on a strip plate, with the hole penetrating the strip plate. The end of the guide assembly extends into the slide rail assembly 7, and one end of the push rod 12 is sleeved with the end of the guide assembly extending into the slide rail assembly 7 through its strip-shaped hole. The end of the slide rail assembly 7 can also move along the strip-shaped hole. When the second transmission assembly drives the push rod 12 to move, the push rod 12 drives the end of the guide assembly to move simultaneously along the slide rail assembly 7 and the strip-shaped hole. To enable the second transmission assembly to drive the push rod 12 to move, and simultaneously drive the brewing cup 6 to move horizontally and vertically along the slide rail assembly 7, the length of the push rod 12 and the orientation of the slide rail assembly 7 need to be flexibly adjusted according to the actual space of the device; the specific dimensions are not fixed.

[0074] In this embodiment, to ensure the stable movement of the brewing cup 6 and prevent tilting of the rim and bottom during movement, the slide rail assembly 7 includes two sets of slide rails arranged opposite each other within the body 1. A guide assembly is connected to both sets of slide rails. For example, the guide assembly includes a driving member and a driven member. A second transmission assembly is connected to the driving member, driving the driven member to move synchronously. In this embodiment, each set of slide rails includes a horizontally arranged first slide rail and a vertically arranged second slide rail. The first and second slide rails are interconnected, but the specific connection position is uncertain.

[0075] In another embodiment, the fully automatic coffee maker further includes a Hall element 16, a water supply assembly 13 connected to the brewing cup 6, a pusher mechanism 14 with one end extending into the brewing cup 6 to support coffee grounds and capable of moving up and down along the cup wall of the brewing cup 6, and a control system. The portion of the pusher mechanism 14 located inside the brewing cup 6 matches the bottom structure of the cup and can move up and down along the cup wall. The control system is connected to the grinder 2, the water supply assembly 13, and the pusher mechanism 14 to control the grinder 2 to grind coffee grounds, the water supply assembly 13 to supply water to the brewing cup 6, and to control the pusher mechanism 14 to move and remove the coffee puck after brewing. The Hall element 16 is used to monitor and collect the kinetic energy output by the drive mechanism 4. For example, if the drive mechanism 4 includes a motor, the Hall element 16 monitors and collects the motor speed. The control system is connected to both the Hall element 16 and the drive mechanism 4. It is used to start the drive mechanism 4 and regulate the operation of the drive mechanism 4 according to the kinetic energy output by the drive mechanism 4 sensed by the Hall element 16. For example, it can adjust the speed of the motor based on the obtained speed information, thereby adjusting the powder pressing force.

[0076] In one application embodiment, when the fully automatic coffee brewing device is in normal operation, as shown in Figures 4 to 7, the process includes:

[0077] The control system controls the operation of the grinder 2, and the coffee powder is evenly sprinkled into the vertically arranged brewing cup 6 through the vertical powder channel, so that the coffee powder does not easily accumulate on the side wall of the brewing cup 6.

[0078] After the coffee powder is collected, the control system drives the drive mechanism 4 via an electrical signal. The brewing mechanism drives the screw (first transmission rod 8) to rotate via its gearbox 15, which in turn drives the screw sleeve (first transmission component 9) to move along the screw. The screw sleeve drives the push rod 12 to move on the second transmission rod 10 via the second transmission component 11. The push rod 12 is connected to the brewing cup 6 via a guide component, which in turn drives the brewing cup 6 to move along the first slide rail, so that it moves to below the brewer assembly 3. Then, the brewing cup 6 moves back and forth along the second slide rail. At the same time, the control system controls the water supply component 13 to continuously supply water into the brewing cup 6. With the up and down reciprocating movement of the brewing cup 6, the brewer assembly 3 can extend into and out of the brewing cup 6 to vertically tamp the coffee powder in the brewing cup 6 and assist in vertical anti-gravity brewing of coffee. The vertical tamp process can effectively ensure that the coffee powder is subjected to uniform force during the tamping process. The tamping force is detected by the Hall element 16, which detects the output kinetic energy of the drive mechanism 4, such as the motor speed, and transmits it to the control system, which then controls the tamping action to complete the process. The vertical brewing process effectively ensures stable pressure during brewing and allows for the effective penetration of fine coffee powder that has settled at the bottom of the brewing cup, preventing coffee powder from settling.

[0079] After the coffee is brewed, the control system controls the drive mechanism 4 and the transmission mechanism 5 to drive the brewing cup 6 to move along the slide rail to reset. The coffee grounds in the chamber of the brewing cup 6 are moved out of the brewing cup 6 by the control system controlling the push rod mechanism 14. At this time, the brewing cup 6 stays in the initial position and is ready for the next coffee brewing.
