Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coffee machine technology, specifically relating to an automatic coffee brewing machine. Background Technology
[0002] Early coffee machines used simple electromechanical controls to pressurize and extract coffee beans. Core components included a heating module, water pump, coffee grounds container, and filter system. The design of these core components enabled the machine to automatically grind, dispense water, and heat the beans. For example, the grinding system had a built-in electric grinder that used rotating blades to grind coffee beans to the appropriate particle size (coarse / medium / fine grinds for different brewing methods), allowing users to adjust the grind to their preferred taste. However, these modules operated independently, lacking intelligent interaction. Especially during the brewing process, the need for the external coffee grounds container hindered automation.
[0003] Most existing coffee machines have a powder cup that is clipped under the grinder. After the powder is collected, the powder cup needs to be removed manually and then manually fixed under the water inlet for brewing. The whole process requires manual movement of the powder cup, which is quite cumbersome. Summary of the Invention
[0004] To address the problems in related technologies, this utility model proposes an automatic coffee brewing machine. Through a drive motor, rack and pinion, gears, and connecting bracket, the coffee powder cup moves horizontally at the lower end of the grinding device and the water injection device.

[0019] Specifically, two longitudinally arranged side plates are perpendicular to the slide rod. The slide rod passes through the rod hole in the side plate of the sliding part, allowing the sliding part to slide back and forth on the slide rod.
[0020] Preferably, the motor connecting plate is formed by extending from the upper end of the sliding part towards the rack side; the motor connecting plate is parallel to the horizontal plane; the drive motor is disposed on the motor connecting plate and connected to the motor connecting plate.

The connection between the drive motor, the connecting bracket, and the coffee maker allows the connecting bracket and the coffee maker to move synchronously as well. Therefore, after coffee powder is added to the coffee maker, it automatically moves to the lower end of the water-filling device, achieving automatic brewing and improving the user experience. Furthermore, by cleverly utilizing the connection between the drive motor and the connecting bracket, the drive unit serves as both the power source and the connecting medium, enabling the translation of the coffee maker and simplifying the structural design.

[0042] Example
[0043] like Figures 1 to 7 An automatic coffee maker includes a housing 1 and a grinding device 2 and a water dispensing device 3 arranged side by side within the housing 1;
[0044] The lower end of the grinding device 2 and the water injection device 3 is provided with a movable powder cup 5, and a translation device 4 is connected to the powder cup 5.

The connecting bracket 45 is connected to the drive motor 43, and the powder cup 5 is connected to the connecting bracket 45.
[0045] The drive motor 43 drives the gear 42 to rotate. While the gear 42 rotates and meshes with the rack 41 to move, it also drives the drive motor 43 to move. The drive motor 43 drives the connecting bracket 45 and the powder cup 5 to move back and forth along the slide rod 44 at the lower end of the grinding device 2 and the water injection device 3.
[0046] The grinding device 2 is used to grind coffee beans into coffee powder and dispense the powder into the powder cup 5 at the lower end. The water dispensing device 3 is used to dispense water into the powder cup 5 at the lower end for brewing.
[0047] The distance between the water injection device 3 and the powder cup 5 is greater than the distance between the grinding device 2 and the powder cup 5.
[0048] The drive motor 43 has a motor shaft 431, and the drive shaft of the drive motor 43 is connected to the central shaft where the gear 42 is located.
[0049] The motor shaft 431 of the drive motor 43 passes through the central shaft of the gear 42 and is connected to it to provide rotational driving force, thereby causing the gear 42 to roll laterally along the rack 41. The lateral rolling of the gear 42 in turn drives the drive motor 43 to translate, so that the drive motor 43 drives the connecting bracket 45 and the powder cup 5 to translate. The structure design is simple.
[0050] The rack 41 has a fixing plate 411 perpendicular to the rack 41 at both ends. The two fixing plates 411 extend toward the side where the slide rod 44 is located and are connected to the two ends of the slide rod 44 respectively.
[0051] The rack 41 is horizontally positioned and moves horizontally in conjunction with the gear 42; the fixed plate 411 is used to connect the slide rod 44, and the gear 42 is located between the slide rod 44 and the rack 41.

[0053] The fixing plate 411 is also provided with screw holes, through which the fixing plate 411 is fixed in the housing 1.
[0054] At least two transverse sliding rods 44 are provided between the two fixed plates 411, and the sliding rods 44 are arranged vertically and parallel to each other.
[0055] This embodiment includes two sliding rods 44 arranged vertically, which can improve the stability of the connecting bracket 45 when it moves.
[0056] The connecting bracket 45 includes a motor connecting plate 451, a sliding part 452, and a powder cup connecting arm 453; the sliding part 452 is connected to the motor connecting plate 451 and the powder cup connecting arm 453 respectively, and the motor connecting plate 451, the sliding part 452, and the powder cup connecting arm 453 are integrally formed.
[0057] The sliding part 452 is arranged longitudinally, the motor connecting plate 451 and the powder cup connecting arm 453 are arranged horizontally and extend in different directions, connecting the drive motor 43 and the powder cup 5 together on the connecting bracket 45.
[0058] The sliding part 452 has a vertical plate-like structure. Two parallel side plates 4521 are formed by extending from both sides of the plate-like structure of the sliding part 452 toward the gear 42. The two side plates 4521 are respectively provided with rod holes 4522 that are adapted to the slide rod 44. The slide rod 44 passes through the rod holes 4522 of the two side plates 4521 and is slidably connected to the connecting bracket 45.
[0059] Two longitudinally arranged side plates 4521 are perpendicular to the slide rod 44. The slide rod 44 passes through the rod hole 4522 of the side plate 4521 of the sliding part 452, so that the sliding part 452 slides back and forth on the slide rod 44.
[0060] The motor connecting plate 451 is formed by extending from the upper end of the sliding part 452 toward the side where the rack 41 is located; the motor connecting plate 451 is parallel to the horizontal plane; the drive motor 43 is disposed on the upper part of the motor connecting plate 451 and is connected to the motor connecting plate 451.
[0061] The motor connecting plate 451 is not connected to the gear 42; the connection between the motor connecting plate 451 and the drive motor 43 enables the drive motor 43 to move synchronously with the connecting bracket 45.
[0062] The powder cup connecting arm 453 extends from the lower end of the sliding part 452 toward the side away from the rack 41, and the powder cup connecting arm 453 extends to the outside of the housing 1 and is connected to the powder cup 5.
[0063] The powder cup connecting arm 453 can be a rectangular plate structure, and the plane of the powder cup connecting arm 453 is parallel to the motor connecting plate 451.
[0064] The powder cup 5 is provided with a connecting part 51, which is sleeved on the outside of the powder cup connecting arm 453 and is engaged with the powder cup connecting arm 453.
[0065] The connecting part 51 is adapted to the powder cup connecting arm 453; the powder cup connecting arm 453 is used to connect with the powder cup 5, so that the drive motor 43, the connecting bracket 45 and the powder cup 5 move synchronously.
[0066] This utility model provides an automatic coffee brewing machine. In the initial state, the coffee powder cup 5 is located at the lower end of the grinding device 2. After the grinding device 2 grinds coffee beans into coffee powder, the coffee powder is added to the coffee powder cup 5. The drive motor 43 starts to work, driving the gear 42 to rotate. When the gear 42 rolls laterally along the rack 41, it drives the drive motor 43 to move horizontally. Since the drive motor 43 is connected to the connecting bracket 45, and the connecting bracket 45 is connected to the coffee powder cup 5, the connecting bracket 45 and the coffee powder cup 5 move synchronously with the drive motor 43. The coffee powder cup 5 moves horizontally from below the grinding device 2 to below the water injection device 3. The water injection device 3 injects water into the coffee powder cup 5 and automatically completes the coffee brewing.
