[0002] A coffee machine is a machine used to make coffee. It makes coffee by grinding coffee beans, pressurizing steam or using a water pump, etc. Coffee machines usually have multiple functions, such as adjusting the coffee strength and making different types of coffee; they are widely used in homes, offices, coffee shops and other places.

[0003] Current coffee machines grind coffee beans using a grinding device. The coffee beans are ground into coffee powder, which is then poured into the brewing tank for extraction and brewing. Finally, the brewed coffee is delivered to the coffee cup through the water outlet valve in the extractor, completing the coffee brewing process.

[0004] In existing grinding devices, the coarseness of coffee powder is adjusted by turning a knob. Rotating the knob, via a worm gear and adjusting gear, adjusts the distance between the upper and lower blades. However, when the knob rotates the worm gear, the worm is prone to axial runout, causing the upper blade connected to the adjusting gear to float. This makes it difficult to maintain a consistent coarseness of the coffee powder, thus affecting the consistency of the coffee's flavor.

[0037] Example 1

[0038] See Figure 1-6 As shown, the coffee machine grinding device includes a body 1, a storage bin 2 on top of the body 1, a grinding mechanism 3 inside the body 1, and a powder receiving mechanism 4 on one side of the body 1. The output end of the storage bin 2 is connected to the input end of the grinding mechanism 3, and the input end of the powder receiving mechanism 4 is connected to the output end of the grinding mechanism. The device also includes an adjustment mechanism 5, comprising: an adjustment gear 51 installed above or below the grinding mechanism 3; a mounting bracket 52 installed on one side of the grinding mechanism 3; a worm gear 53 installed on the mounting bracket 52, one side of which meshes with the adjustment gear 51 to drive the adjustment gear 51 to rotate; and a knob 54 installed on the first end of the mounting bracket 52, its inner side connected to the worm gear 53 to drive the worm gear 53 to rotate. It should be noted that in this embodiment, the first end of the mounting bracket 52 is threaded, and the inner side of the knob 54 is also threaded, allowing it to be rotated onto the mounting bracket 52 via these threads. The fixing component 55 has a first end installed on the outside of the knob 54, and a second end extending into the mounting bracket 52, passing through the worm gear 53, and installed at the second end of the mounting bracket 52.

[0039] By setting the fixing component 55, the knob 54 and the worm gear 53 are connected as one unit, thereby avoiding the axial runout of the worm gear 53, ensuring that the coarseness of the coffee powder remains consistent, and ensuring that the consistency of the coffee taste is not affected.

[0040] In a further technical solution, the fixing component 55 includes a connector 551 and a fixing component 552. The first end of the connector 551 is mounted on the outside of the knob 54, and the second end of the connector 551 passes through the mounting bracket 52 and the worm gear 53 and connects to the fixing component 552. Through the cooperation of the connector 551 and the fixing component 552, the knob 54 and the worm gear 53 are connected as a single unit.

[0041] In a preferred embodiment, the connector 551 is a screw, and the fixing member 552 is a nut. The screw is screwed to the nut, and the knob 54 and the worm gear 53 are respectively provided with through holes 56 for the screw to pass through. The screw passes through the through hole 56 and is screwed to the nut. It can be understood that the knob 54 has a groove in the through hole 56 for accommodating the screw.

[0042] In other specific embodiments, the connector 551 may also be a pin, shaft or other connector 551 to achieve the same function as the screw.

[0043] In a further technical solution, a latching part 531 is provided in the middle of the worm gear 53. An elastic element 532 and a locking block 533 matching the latching part 531 are provided on the side of the worm gear 53 near the knob 54. The elastic element 532 and the locking block 533 are respectively fitted onto the worm gear 53. The first end of the elastic element 532 abuts against the knob 54, and the second end of the elastic element 532 abuts against the first end of the locking block 533. The second end of the locking block 533 abuts against the first end of the latching part 531. As a preferred embodiment, the elastic element 532 in this embodiment is a spring. In other specific embodiments, the elastic element 532 can also be rubber or other elastic components.

[0044] The elastic element 532 provides a certain radial resistance to the knob 54 and the locking block 533 respectively, so that the locking block 533 is always close to the locking part 531 of the worm gear 53.

[0045] In a further technical solution, the outer wall of the card block 533 protrudes outward to form multiple limiting parts 5331, and the inner wall of the mounting bracket 52 is recessed inward to form multiple limiting grooves 521, with one of the limiting parts 5331 extending into one of the limiting grooves 521.

[0046] By cooperating with the limiting part 5331 and the limiting groove 521, the locking block 533 is fixed to the inner wall of the mounting bracket 52, so that when the knob 54 drives the worm gear 53 to rotate, the locking block 533 remains fixed and does not move. The structure is simple and the fixing effect is good.

[0047] In existing technology, the knob 54 and the worm gear 53 are usually connected by a snap-fit ​​mechanism. That is, a mounting groove 541 is provided in either the worm gear 53 or the knob 54, and the worm gear 53 or the knob 54 extends into the mounting groove 541 for connection. In this embodiment, the knob 54 has a mounting groove 541 on its inner side, and the worm gear 53 extends into the mounting groove 541 and snaps into the knob 54. When the knob 54 rotates the worm gear 53, there is no sound, which makes it impossible for the user to know whether the adjustment is effective.

[0048] Therefore, in this embodiment, the second end of the locking block 533 and the first end of the latching part 531 are recessed inward to form a plurality of locking grooves 534, and the second end of the locking block 533 and the first end of the latching part 531 are protruding outward to form a plurality of locking protrusions 535. The locking protrusions 535 of the locking block 533 extend into the locking grooves 534 of the latching part 531 and cooperate with them, and the locking protrusions 535 of the latching part 531 extend into the locking grooves 534 of the locking block 533 and cooperate with them.

[0049] When the knob 54 is turned, the locking protrusions 535 will successively exit from the locking slot 534 and enter the adjacent locking slot 534, thus making a clicking sound. The sound is crisp and makes the user understand that the adjustment is effective.

[0050] It should be noted that in this embodiment, both the latching protrusion 535 and the latching groove 534 are arc-shaped, and adjacent latching protrusions 535 and adjacent latching grooves 534 have arc-shaped transitions. This configuration is simple in structure, low in cost, and exhibits minimal wear during relative rotational movement of the latching protrusion 535 and the latching groove 534. In other specific embodiments, both the latching protrusion 535 and the latching groove 534 are serrated.

[0051] In a further technical solution, the mounting bracket 52 has a through groove 522 on the side near the adjusting gear 51, and the rotating teeth of the worm gear 53 are exposed in the through groove 522 and mesh with the adjusting gear 51.

[0052] The through slot 522 allows the worm gear 53 to directly mesh with the adjusting gear 51 within the mounting bracket 52, resulting in a simple structure and convenient installation.

[0053] In a further technical solution, a scale 511 is provided on the top or bottom of the adjusting gear 51, and the scale 511 is provided with a plurality of indicators 512 for displaying the adjustment level, the plurality of indicators 512 surrounding the scale 511. The adjusting gear 51 is a helical gear.

[0054] The dial 511 is designed so that when the worm gear 53 drives the adjusting gear 51 to rotate, the dial 511 will rotate along with the adjusting gear 51. Consequently, the mark 512 on the dial 511 will also rotate with the dial 511. Therefore, the user can determine the fineness of the powder being ground by referring to the mark 512 located directly in front of the dial 511. The structure is simple and the performance is good.

[0055] The terms "specific example" or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
