Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of coffee machines, and particularly to a fully automatic coffee brewing device. Background Art

[0002] At present, for fully automatic coffee brewing devices on the market, such as the coffee brewing device disclosed in the Chinese patent with the publication number CN106859344B, when receiving coffee powder, pressing the coffee powder, and brewing coffee, the brewing chamber first vertically receives the powder and then rotates a certain angle to enter the powder pressing and brewing track. When the brewing chamber vertically receives the coffee powder, the coffee powder will not accumulate on one side of the brewing chamber. However, when pressing and brewing the coffee powder, since the brewing chamber is inclined, the coffee powder in the brewing chamber will accumulate on one side under the action of gravity, resulting in uneven force on the coffee powder cake during the powder pressing process. Therefore, when brewing coffee, over-extraction occurs on one side due to the accumulation of coffee powder, and under-extraction occurs on the other side due to the lack of coffee powder, ultimately affecting the extraction effect of coffee. Summary of the Invention

[0003] The embodiments of the present invention provide a fully automatic coffee brewing device that can prevent uneven powder pressing of coffee powder and ensure uniform brewing of coffee powder.

[0004] To solve the above technical problems, the embodiments of the present invention provide a fully automatic coffee brewing device, including:

[0009] A transmission mechanism, provided in the machine body and connected to the driving mechanism to be driven by the driving mechanism;

[0010] A brewing cup, provided in the machine body and located below the grinder for receiving coffee powder. The powder outlet direction of the coffee powder is perpendicular to the plane where the cup mouth of the brewing cup is located. The brewing cup is simultaneously connected to the transmission mechanism and the slide rail assembly. When the driving mechanism drives the transmission mechanism to operate, the transmission mechanism drives the brewing cup to move along the slide rail assembly, so that the brewing cup moves below the brewing component and reciprocates in the direction of approaching and departing from the brewing component, enabling the brewing component to complete powder pressing of the coffee powder in the brewing cup in the direction perpendicular to the plane where the cup mouth is located.

[0011] In one embodiment, when the driving mechanism drives the transmission mechanism to operate, the transmission mechanism drives the brewing cup to horizontally move from a first position to a second position along the slide rail assembly, and drives the brewing cup to reciprocate in the vertical direction along the slide rail assembly at the second position. The first position is below the grinder, and the second position is below the brewing component.

[0012] In one embodiment, a guiding component is connected to the brewing cup. The end of the guiding component is limited within the slide rail assembly and can move along the slide rail assembly, thereby driving the brewing cup to move along the slide rail assembly.

When the driving mechanism drives the first transmission component, the first transmission component synchronously drives the second transmission component. When the second transmission component moves, it drives the guiding component to move along the slide rail assembly through the push rod.

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

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

[0024] The driving 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 the length direction on a strip-shaped plate. The strip-shaped hole penetrates the strip-shaped plate. One end of the push rod is sleeved with the end of the guiding component extending into the slide rail component through its strip-shaped hole. The end of the slide rail component can simultaneously move along the strip-shaped hole. When the second transmission component drives the push rod to move, the push rod drives the end of the guiding component to move along the slide rail component and the strip-shaped hole simultaneously.

[0026] In one embodiment, the slide rail component includes two groups of slide rails oppositely arranged in the machine body. Each group of slide rails includes a horizontally arranged first slide rail and a vertically arranged second slide rail. The brewing cup is simultaneously connected to the two groups of slide rails and can move along them.

[0027] In one embodiment, it further includes a Hall element, a water supply component connected to the brewing cup, a push rod mechanism with one end extending into the brewing cup for supporting coffee powder and capable of moving up and down along the inner wall of the brewing cup, and a control system. The control system is connected to the grinder, the water supply component, and the push rod mechanism to control the grinder to grind coffee, the water supply component to supply water, and control the movement of the push rod mechanism to remove the coffee powder cake after brewing. The control system is simultaneously connected to the Hall element and the driving mechanism to start the driving mechanism and regulate the operation of the driving mechanism according to the kinetic energy output by the driving mechanism sensed by the Hall element.

[0048] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0050] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of the present invention provides a fully automatic coffee brewing device, including:

[0051] A body 1, internally provided with a slide rail assembly 7;

[0052] A grinder 2, provided in the body 1;

[0053] A brewing component 3, provided in the body 1,

[0054] A driving mechanism 4, provided in the body 1;

[0055] The transmission mechanism 5 is disposed within the machine body 1 and is connected to the drive mechanism 4 to be driven by the drive mechanism 4.

[0056] The brewing cup 6 is disposed within the machine body 1 and is located below the coffee grinder 2 for receiving coffee powder. The powder outlet direction of the coffee powder is perpendicular to the plane where the cup mouth of the brewing cup 6 is located. The brewing cup 6 is simultaneously connected to the transmission mechanism 5 and the slide rail assembly 7. When the drive mechanism 4 drives the transmission mechanism 5 to operate, the transmission mechanism 5 drives the brewing cup 6 to move along the slide rail assembly 7, so that the brewing cup 6 moves below the brewing component 3 and reciprocates in the direction of approaching and departing from the brewing component 3, enabling the brewing component 3 to complete the powder pressing of the coffee powder in the brewing cup 6 in the direction perpendicular to the plane where the cup mouth is located.

[0057] In this embodiment, the transmission mechanism 5 is connected to the brewing cup 6. At the same time, the brewing cup 6 is connected to the slide rail assembly 7 and can move along the slide rail assembly 7. The initial position, or rather the default position, of the brewing cup 6 in this embodiment is below the coffee grinder 2 to facilitate receiving coffee powder. After the powder receiving is completed, the drive mechanism 4 operates to drive the transmission mechanism 5, causing the transmission mechanism 5 to drive the brewing cup 6 to move along the slide rail assembly 7 below the brewing component 3 and reciprocate in the direction of approaching and departing from the brewing component 3, enabling the brewing component 3 to extend into and retract from the brewing cup 6, thereby completing the powder pressing operation, and then the coffee extraction operation can be carried out.

[0058] After the coffee extraction is completed, the drive mechanism 4 can also drive the transmission mechanism 5 to cause the transmission mechanism 5 to drive the brewing cup 6 to move reversely along the slide rail assembly 7, thereby resetting to its initial position and preparing for the next coffee brewing.

[0059] Based on the above embodiments, it can be seen that the overall design structure of the device in this embodiment is simple. By only arranging the drive mechanism 4, the transmission mechanism 5, and the slide rail assembly 7 within the device, the brewing cup 6 can be moved within the device through each mechanism and component, enabling the brewing cup 6 not only to receive powder vertically but also to achieve vertical powder pressing of the coffee powder in the brewing cup 6, ensuring uniform pressing of the coffee powder cake, and further enabling uniform brewing of the coffee powder during brewing, achieving a better coffee extraction effect. Moreover, since the coffee powder cake is pressed evenly, there will be no situation where the coffee powder is accumulated at the bottom edge of the cup due to uneven powder pressing in the brewing cup 6, such as due to the inclination of the brewing cup 6, making it difficult to clean and causing pollution to the brewing environment, affecting the brewing taste of subsequent coffee.

[0060] Further, when the driving mechanism 4 drives the transmission mechanism 5 to operate in this embodiment, the transmission mechanism 5 drives the brewing cup 6 to horizontally move from the first position to the second position along the slide rail assembly 7, and drives the brewing cup 6 to reciprocate in the vertical direction along the slide rail assembly 7 at the second position. 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 position and the second position. When the brewing cup 6 is at the second position, the control causes the brewing cup 6 to reciprocate up and down in the vertical direction. During the movement of the brewing cup 6, the plane where the cup mouth of the brewing cup 6 is located is always parallel to the horizontal plane, that is, the cup mouth of the brewing cup 6 always remains horizontal, so that the coffee powder can be evenly distributed on the bottom of the cup whether during tamping or powder receiving.

[0061] In this embodiment, a guiding component is connected to the brewing cup 6. The specific structure of the guiding component is not limited. For example, it can be two connecting pieces respectively connected to the brewing cup 6, or two shaft bodies respectively connected to the brewing cup 6, etc., which is not specifically limited. The end of the guiding component is limited within the slide rail assembly 7 and can move along the slide rail assembly 7. The transmission mechanism 5 is connected to the guiding component, and thus drives the brewing cup 6 to move along the slide rail assembly 7.

[0062] Specifically, in combination with Figure 2 and Figure 3 as shown, the transmission mechanism 5 includes:

[0063] A first transmission component, arranged in the vertical direction and connected to the driving mechanism 4;

[0064] A second transmission component, arranged in the vertical direction and connected to the first transmission component;

[0065] A push rod 12, with one end connected to the guiding component and the other end connected to the second transmission component. When the driving mechanism 4 drives the first transmission component, the first transmission component synchronously drives the second transmission component. When the second transmission component moves, it drives the guiding component to move along the slide rail assembly 7 through the push rod 12.

[0066] That is, the driving mechanism 4 transfers the kinetic energy to the second transmission component through the first transmission component, and then the second transmission component transfers the kinetic energy to the guiding component through the push rod 12. Finally, the kinetic energy is transferred to the brewing cup 6 through the guiding component to drive the brewing cup 6 to move.

[0067] In this embodiment, the first transmission component includes:

[0068] A first transmission rod 8, arranged in the vertical direction and connected to the driving mechanism 4;

[0069] The first transmission member 9 is provided 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.

[0070] The second transmission assembly includes:

[0071] A second transmission rod 10 is arranged in the vertical direction, that is, parallel to the first transmission rod;

[0072] A second transmission member 11 is provided on the second transmission rod 10 and is connected to the first transmission member 9 to move along the second transmission rod 10 under the drive of the first transmission member 9.

[0073] In an application embodiment, the first transmission rod 8 is a screw rod, a stopper is fixed to the top thereof, the first transmission member 9 is a nut sleeve, when the screw rod rotates, it can drive the nut sleeve to move up and down along the screw rod, and the stopper is used to limit the nut sleeve to prevent it from moving out of the screw rod. The driving mechanism 4 includes a motor and a gearbox 15, and the top end of the first transmission rod is connected to the gearbox 15.

[0074] Combined Figure 3 As shown, in this embodiment, the push rod 12 is formed by opening a strip hole along the length direction on a strip plate, and the strip hole penetrates through the strip plate. The end of the guiding assembly extends into the slide rail assembly 7, and one end of the push rod 12 is sleeved with the end of the guiding assembly extending into the slide rail assembly 7 through its strip hole. The end of the slide rail assembly 7 can also move along the strip hole at the same time. When the second transmission assembly drives the push rod 12 to move, the push rod 12 drives the end of the guiding assembly to move along the slide rail assembly 7 and the strip hole at the same time. In order to enable the second transmission assembly to drive the push rod 12 to move, and at the same time 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 setting orientation of the slide rail assembly 7 need to be flexibly adjusted in combination with the actual space of the device, and the specific values are not fixed.

[0075] In this embodiment, in order to enable the brewing cup 6 to move stably and ensure that the cup mouth and cup bottom of the brewing cup 6 are not tilted during the movement, the slide rail assembly 7 includes two groups of slide rails oppositely arranged in the machine body 1, and the guiding assembly is connected to both groups of slide rails at the same time. For example, the guiding assembly includes a driving member and a driven member, and the second transmission assembly is connected to the driving member to drive the driven member to move synchronously by driving the driving member. In this embodiment, each group of slide rails includes a first slide rail arranged horizontally and a second slide rail arranged vertically, and the first slide rail and the second slide rail are connected to each other, and the specific connection position is not fixed..

[0076] In another embodiment, the fully automatic coffee device further includes a Hall element 16, a water supply assembly 13 connected to the brewing cup 6, a push rod mechanism 14 with one end extending into the brewing cup 6 for supporting coffee powder and capable of moving up and down along the inner wall of the brewing cup 6, and a control system. The part of the push rod mechanism 14 located inside the brewing cup 6 matches the bottom structure of the cup and can move up and down along the inner wall of the cup. The control system is connected to the coffee grinder 2, the water supply assembly 13, and the push rod mechanism 14 to control the coffee grinder 2 to grind coffee beans and output coffee powder, the water supply assembly 13 to supply water into the brewing cup 6, and to control the movement of the push rod mechanism 14 to remove the coffee powder cake after brewing is completed. The Hall element 16 is used to monitor and collect the kinetic energy output by the driving mechanism 4. For example, if the driving mechanism 4 includes a motor, the Hall element 16 monitors and collects the motor speed. The control system is also connected to the Hall element 16 and the driving mechanism 4, used to start the driving mechanism 4 and regulate the operation of the driving mechanism 4 according to the kinetic energy output by the driving mechanism 4 sensed by the Hall element 16. For example, the motor speed is adjusted based on the obtained speed information, so as to adjust the pressing force of the coffee powder.

[0077] In an application embodiment, when the fully automatic coffee brewing device is in normal use, as Figures 4 to 7 shown, the process includes:

[0078] The control system controls the coffee grinder 2 to work, and the coffee powder is evenly scattered into the vertically arranged brewing cup 6 through the vertical powder channel, and the coffee powder is not easy to accumulate on the side wall of the brewing cup 6;

[0079] After the powder receiving is completed, the control system drives the driving mechanism 4 to operate through an electrical signal. The brewing mechanism drives the screw rod (the first transmission rod 8) to rotate through its gearbox 15, and then drives the screw sleeve (the first transmission member 9) to move along the screw rod. The screw sleeve drives the push rod 12 to move on the second transmission rod 10 through the second transmission member 11. The push rod 12 is connected to the brewing cup 6 through the guiding assembly, and then drives the brewing cup 6 to move along the first slide rail, so that it moves below the brewing device assembly 3, and then drives the brewing cup 6 to reciprocate along the second slide rail. At the same time, the control system controls the water supply assembly 13 to continuously supply water into the brewing cup 6. As the brewing cup 6 reciprocates up and down, the brewing device assembly 3 can be extended into and retracted from the brewing cup 6 to vertically press the coffee powder in the brewing cup 6 and assist in the vertical reverse gravity brewing of the coffee. The vertical powder pressing process can effectively ensure that the coffee powder is evenly stressed during the powder pressing process. The pressing force of the coffee powder is detected by the Hall element 16 for the output kinetic energy of the driving mechanism 4, such as the motor speed, and uploaded to the control system, and the control system controls the powder pressing action to be completed. Through the vertical brewing process, the pressure during the brewing process can be effectively ensured to be stable, and it can effectively penetrate and precipitate the fine powder at the bottom of the brewing cup 6, avoiding the deposition of coffee powder.

[0080] After the coffee brewing is completed, the control system controls the drive mechanism 4 and the transmission mechanism 5 to drive the brewing cup 6 to perform a reset movement along the slide rail. The coffee powder residue in the chamber of the brewing cup 6 is removed from the brewing cup 6 by the control system's control of the push rod mechanism 14. At this time, the brewing cup 6 stays at the initial position to prepare for the next coffee brewing.

The protection scope of the present invention is defined by the claims.
