Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model provides, for example Figure 1-4The diagram illustrates an automatic coffee powder dispensing device for a coffee machine, used to dispense a measured amount of ground coffee powder. It includes a storage cylinder 1 fixedly mounted to the output end of the coffee grinder. The bottom of the storage cylinder 1's inner cavity is truncated cone-shaped, and a powder outlet 11 is located at the bottom of the inner cavity. A groove 2, communicating with the powder outlet 11, passes through the storage cylinder 1. A first component 3 is slidably connected within the groove 2. One end of the first component 3 passes through a powder dispensing groove 4. The diameter of the powder outlet 11 is the same as the width of the powder dispensing groove 4. A second component 5 is slidably connected within the powder dispensing groove 4. The end of the powder dispensing groove 4 away from the second component 5 has a semi-circular protrusion 12, and the end of the second component 5 near the storage cylinder 1 has a semi-circular groove 13. The diameters of both the semi-circular protrusion 12 and the semi-circular groove 13 are the same as the width of the powder outlet 11. A rear sleeve 6, slidably connected to the first component 3, is fixedly connected to one side of the storage cylinder 1. An electric telescopic rod 7 is fixedly mounted at the bottom of the storage cylinder 1. A control mechanism for adjusting the position of the second component 5 within the powder dispensing groove 4 is installed at the end of the output shaft of the electric telescopic rod 7. The control component 8 includes a motor 8a fixedly mounted on the output shaft end of the electric telescopic rod 7, a threaded rod 8b fixedly mounted on the output shaft end of the motor 8a, a through groove 8c opened inside the second part 5, and a slide rod 8d fixedly connected to the end of the first part 3. The slide groove 2 passes through the through groove 8c and is slidably connected to the through groove 8c. The threaded rod 8b passes through the slide rod 8d and is threadedly connected to the slide rod 8d. The threaded rod 8b is rotatably connected to the second part 5. A front sleeve 9 is fixedly mounted on the other side of the storage cylinder 1 and is slidably connected to the first part 3. A stop groove 14 is opened on the top of the front sleeve 9. A stop block 15 is fixedly mounted on the end of the first part 3 away from the top of the second part 5. The stop block 15 is slidably connected to the stop groove 14. The end of the stop block 15 matches the shape of the storage cylinder 1. The width of the stop groove 14 is the same as the diameter of the powder outlet 11. When the stop block 15 is in contact with the outer wall of the storage cylinder 1, the semi-circular protrusion 12 is located directly below the powder outlet 11. A powder outlet pipe 10 is fixedly mounted on the bottom of the front sleeve 9.

[0025] After the grinder grinds the coffee beans into coffee powder, the powder falls into the storage cylinder 1 and then into the semi-circular groove 13 at the end of the second piece 5 through the powder outlet 11. Then, the output shaft of the electric telescopic rod 7 extends, thereby driving the motor, the threaded rod 8b, the second piece 5 and the first piece 3 to slide out of the slide groove 2 in sequence. As the first piece 3 and the second piece 5 slide, the coffee powder gradually falls into the powder metering tank 4 through the powder outlet 11. Finally, when the powder outlet 11 is directly above the semi-circular convex groove 12, the powder metering tank 4 is full of coffee powder.

[0026] Then the output shaft of the electric telescopic rod 7 shortens, causing the first piece 3 and the second piece 5 to move toward the powder outlet tube 10. When the powder metering tank 4 is connected to the top of the powder outlet tube 10, the coffee powder in the powder metering tank 4 falls into the powder outlet tube 10 for the brewer to use.

[0027] When it is necessary to adjust the amount of coffee powder discharged, the automatic start motor 8a rotates. The output shaft of the motor 8a drives the threaded rod 8b to rotate. The threaded rod 8b is connected to the slide rod 8d by a thread, which causes the slide rod 8d to slide in the through groove 8c. This causes the distance of the second rod inserted into the powder metering groove 4 to change, thereby adjusting the length of the powder metering groove 4 and thus adjusting the amount of coffee powder discharged.

[0028] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
