[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0024] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0025] like Figures 1 to 5 As shown, this utility model relates to a coffee brewing powder dropping and residue cleaning device. Its core is to achieve precise powder dropping and efficient residue cleaning of coffee through a rotating table with a specific structure and its related components, while simplifying the equipment operation process and improving the efficiency and quality of coffee brewing.

[0026] This utility model's coffee brewing coffee grounds and grounds removal device mainly includes a rotating platform, a drive assembly 5, and a brewing tank 4. The rotating platform is the key component for realizing the coffee grounds and grounds removal functions, and it integrates a coffee grounds receiving funnel 1, an upper pressure rod assembly 2, and a grounds removal section 3. The shape and size of the coffee grounds receiving funnel 1 can be designed according to the characteristics of the coffee grounds and the size of the brewing tank 4 to ensure that the coffee grounds can fall evenly into the brewing tank 4. For example, the coffee grounds receiving funnel 1 can be designed as a cone or cylinder, and its inner wall can be provided with spiral guide grooves, so that the coffee grounds can be smoothly distributed to various parts of the brewing tank 4 along the guide grooves during the falling process, thereby improving the uniformity of coffee grounds falling.

[0027] The function of the upper pressure bar assembly 2 is to apply pressure to the coffee grounds inside the brewing tank 4 after the coffee grounds have been dispensed, compressing them into a cake shape to facilitate the subsequent extraction process. This assembly includes a pressure bar body and a pressure head. The shape of the pressure head matches the inner wall of the brewing tank 4 and can be round, square, or other suitable shapes. Its material can be food-grade stainless steel or aluminum alloy, ensuring both the strength and durability of the pressure bar assembly while meeting food hygiene requirements. In practical applications, the upper pressure bar assembly 2 can also be equipped with a pressure sensor for precise control of the extrusion pressure, ensuring that coffee grounds of different weights achieve the ideal extrusion effect.

[0028] The cleaning section 3 is used to sweep away the coffee grounds 7 that have risen to the top of the brewing tank 4 during the rotation of the turntable, keeping the brewing tank 4 clean. The cleaning section 3 can adopt various structural forms, such as scraper type, brush type, or airflow type. In this embodiment, a scraper type cleaning section 3 is used, with the scraper having an arc shape, which can better conform to the shape of the coffee grounds 7 and improve the cleaning effect. The scraper can be made of wear-resistant and high-temperature-resistant materials such as polytetrafluoroethylene to adapt to the high-temperature environment during the coffee brewing process.

[0029] In one specific embodiment of this utility model, the cleaning section 3 is located at the bottom of the coffee receiving funnel 1 near the upper pressure rod assembly 2. This positioning allows the cleaning section 3 to contact the coffee cake 7 that has risen to the top of the brewing tank 4 during the rotation of the rotating table, thus enabling more timely cleaning. The first position is when the coffee receiving funnel 1 is directly facing the brewing tank 4 below, at which point the funnel 1 accurately delivers coffee powder into the brewing tank 4. The second position is when the upper pressure rod assembly 2 is directly facing the brewing tank 4 below, at which point the upper pressure rod assembly 2 can compress the coffee powder inside the brewing tank 4. During the transition from the second position to the first position, the cleaning section 3, driven by the drive assembly 5, effectively sweeps away the coffee cake 7, preventing it from remaining inside the brewing tank 4. This layout not only improves the efficiency and reliability of the cleaning process but also optimizes the overall structure of the device, making it more compact and efficient. During the process of the upper pressure rod assembly 2 pressing down and sealing the brewing tank 4, the cleaning section 3 can be pre-adjusted to a suitable position so that cleaning can be performed quickly when the coffee cake 7 is lifted. Furthermore, this positioning reduces interference between the cleaning section 3 and the coffee cake funnel 1, ensuring a smooth coffee cake dispensing process.

[0030] In another embodiment, the cleaning section 3 is located below the upper pressure rod assembly 2 on the side near the powder receiving funnel 1. This positioning also allows the cleaning section 3 to contact the powder cake 7 that has risen to the top of the brewing tank 4 during the rotation of the turntable, thereby achieving timely cleaning operation.

[0031] The function of drive assembly 5 is to rotate the rotary table between the first and second workstations. Drive assembly 5 can be driven by a motor, such as a stepper motor or a servo motor, controlling the rotation direction and angle of the rotary table through the forward and reverse rotation of the motor. The motor's output shaft can be connected to the rotary table via gear transmission, belt transmission, or direct connection to achieve precise control of the rotary table. In practical applications, a suitable motor model and transmission method can be selected based on the specific needs of coffee brewing and the size of the equipment to ensure the performance and reliability of drive assembly 5.

[0032] To further enhance the automation and ease of operation of the device, the drive assembly 5 can also be equipped with sensors and a control system. For example, a position sensor can be installed on the turntable to monitor its position in real time and feed the signal back to the control system. Based on the sensor signals, the control system automatically controls the motor's operation to achieve precise switching of the turntable. Furthermore, the control system can be integrated with other stages of the coffee brewing process, such as automatically activating the downward movement of the upper pressure rod assembly 2 after coffee grounds are dispensed, and automatically activating the cleaning action of the cleaning section 3 after extraction, thereby achieving automated control of the entire coffee brewing process.

[0033] The brewing tank 4 is the core component of coffee brewing, and its internal structure and function are crucial to the quality of coffee and brewing efficiency. In this invention, the brewing tank 4 assembly includes a lifting component 6, a base plate, a central connecting plate, a driven wheel, a water inlet component, the brewing tank 4 itself, and a top cover. The lifting component 6 lifts the coffee pouch 7 above the brewing tank 4 after extraction, allowing the cleaning unit 3 to perform cleaning operations. The lifting component 6 can move up and down via a motor, and the motor's output shaft can be connected to the lifting component 6 via gear or belt drive, enabling precise control of the lifting component 6.

[0034] It may also include an upper water outlet assembly 9 and a lower water inlet assembly 8. The lower water inlet assembly 8 is used to inject hot water into the brewing tank 4 for coffee extraction; the upper water outlet assembly 9 is used to connect to the pump set to discharge the extracted coffee. The lower water inlet assembly 8 can be located at the top of the lifting assembly 6, with the water outlet pipe passing through the middle of the lifting assembly 6 to connect to the outside; the upper water outlet assembly 9 can be located at the bottom of the upper pressure rod assembly 2, with the water inlet pipe of the lower water inlet assembly 8 passing through the middle of the lifting assembly 6 to connect to the outside; the lower water inlet assembly 8 may include components such as a water inlet filter, a water distribution plate, a silicone O-ring, a water inlet plug, a metal connector, and a water inlet pipe; the upper water outlet assembly 9 may include components such as a water outlet filter, a water distribution plate, a silicone O-ring, a water outlet plug, a metal connector, and a water outlet pipe. The water inlet filter is used to prevent the extracted coffee powder from flowing in. The water distribution plate can evenly distribute the water flow to various parts of the brewing tank 4, improving the uniformity of extraction. Silicone O-rings are used to seal the connection between the water inlet assembly and brewing tank 4, preventing water leakage during injection. The inlet nozzle plug and metal connector are used to connect the water inlet pipe, ensuring smooth water flow.

[0035] To further improve the performance and lifespan of the brewing tank 4, the brewing tank 4 assembly can also employ special materials and structural designs. For example, the brewing tank 4 can be made of food-grade stainless steel or ceramic materials, which have good high-temperature resistance and corrosion resistance, ensuring the quality of the coffee and the durability of the equipment. Furthermore, the inner wall of the brewing tank 4 can be provided with special textures or coatings to improve the adhesion of coffee grounds and extraction efficiency. For example, tiny protrusions or grooves can be provided on the inner wall of the brewing tank 4 to increase the contact area between the coffee grounds and hot water, thereby increasing the extraction speed and coffee concentration.

[0036] To further improve the cleaning effect and the flexibility of the device, in one embodiment, the cleaning section 3 adopts an arc-shaped scraper, and a cleaning brush is provided at the bottom of the arc-shaped scraper. The arc-shaped scraper design allows it to better conform to the top surface of the brewing tank 4, improving the cleaning effect. The cleaning brush allows for a more thorough cleaning of the coffee cake 7 on the top of the brewing tank 4, completely removing residual coffee powder and grounds, ensuring the cleanliness of the brewing tank 4. The cleaning brush can be made of soft and wear-resistant materials, such as nylon bristles or pig bristles, to ensure cleaning effectiveness.

[0037] Furthermore, the connection between the cleaning section 3 and the upper pressure rod assembly 2 or the coffee powder receiving funnel 1 can be detachable, such as by threaded connection, snap-fit ​​connection, or magnetic connection. This detachable connection facilitates the cleaning and replacement of the cleaning section 3. When the cleaning section 3 is worn or damaged, the user can easily repair or replace it, reducing equipment maintenance costs and time. In practical applications, cleaning sections 3 of different shapes and sizes can be designed according to different brewing needs and the characteristics of coffee powder to achieve the best cleaning effect. For example, for finer coffee powder, a narrower scraper and a denser cleaning brush can be used; while for coarser coffee powder, a wider scraper and a sparser cleaning brush can be used.

[0038] The overall control logic of the coffee brewing grounds removal device of this utility model is as follows:

[0039] The lower drive motor 11 reverses: it drives the lifting component 6 and the lower water inlet component 8 to move downward, preparing for powder drop and subsequent extraction operations.

[0040] The central drive motor in drive assembly 5 reverses: it stops at the first station, so that the powder receiving funnel 1 is aligned with the brewing tank 4 assembly, and then the powder is discharged.

[0041] After the powder is discharged, the central drive motor rotates forward, causing the upper pressure rod assembly 2 to stop at the second station, ready to compress and seal the powder.

[0042] The upper drive motor rotates forward, driving the upper driven wheel, which in turn presses down the upper pressure rod and the upper water outlet assembly 9, thereby sealing the brewing tank 4 and compressing the powder.

[0043] The lower drive motor 11 rotates forward, driving the lifting assembly 6 and the lower water inlet assembly 8 to move upward, so that the powder is squeezed into a cake shape inside the brewing tank 4.

[0044] Brewing: Extracting coffee, completing the coffee brewing process.

[0045] The upper drive motor reverses: it drives the upper driven wheel, causing the upper pressure rod and the upper water outlet assembly 9 to rise, preparing for the sludge cleaning operation.

[0046] The lower drive motor 11 rotates forward, driving the lifting component 6 and the lower water inlet component 8 to move upward, pushing the extracted powder cake 7 above the brewing tank 4.

[0047] The central drive motor reverses: it moves the rotating table from the second station to the first station, and the slag removal unit 3 sweeps off the powder cake 7 under the drive of the drive component 5, thus completing the slag removal operation.

[0048] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
