Embodiment 1

[0039] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, a gear adjustment structure of a hand-operated coffee grinder includes a main body 4, a main shaft 3, a grinding disc ring 8, and a grinding disc core 10. The grinding disc ring 8 is fixed in the inner cavity of the main body 4, and the grinding disc core 10 is located in the grinding disc In the circle; the upper end of the main shaft is screwed with the adjusting nut 6; the main body 4 is provided with a rotatable supporting member, which supports the lower end surface of the adjusting nut 6, and the supporting member can be a bearing 7, or other supporting components or objects, mainly It can support the adjusting nut. The lower part of the main shaft is connected with the grinding disc core 10 through the interlocking structure that can drive the grinding disc core 10 to rotate together. The grinding disc core 10 can move along the main shaft. Adjust the gap between ...

Embodiment 2

[0048] Embodiment 2: as figure 1 , figure 2 , image 3 , the feature of this example is that the interlocking structure includes a central hole 101 provided by the grinding disc core 10 and a main shaft lower part 31 passing through the central hole, the cross section of the central hole 101 is non-circular, and the cross section of the main shaft bottom is the same as The holes match. Compact structure. All the other are with embodiment 1.

Embodiment 3

[0049] Embodiment 3: as Figure 6 , Figure 7As shown, the feature of this example is that the interlocking structure includes a middle hole 101 provided by the grinding disc core 10 and the lower part 31 of the main shaft 3 passing through the middle hole, the hole wall of the middle hole is provided with a keyway 102, and the lower part of the main shaft A protrusion 32 is provided, the width of which matches the width of the keyway, and the protrusion 32 extends into the keyway 102. During assembly or adjustment, when the disc core moves axially along the main shaft, the protrusion can slide along the keyway. All the other are with embodiment 1. The boss in this example can be made by stamping. The interlocking structure is easy and simple to manufacture. When in use, the main shaft drives the grinding disc core to rotate through the protrusion.

Abstract

The invention discloses a gear adjusting structure of the hand-operated coffee bean grinder. The structure comprises a main body, a main shaft, a grinding disc ring and a grinding disc core, the grinding disc ring is fixed in an inner cavity of the main body, and the grinding disc core is located in the grinding disc ring; the lower end of the main shaft penetrates through the grinding disc core and then is screwed with an adjusting knob through threads; the adjusting button is used for adjusting a gap between the outer side wall of the grinding disc core and the inner side wall of the grinding disc ring; gear marks are fixed to the lower end face of the grinding disc core, and at least two different gears are arranged in the gear marks. A consumer can easily obtain coffee bean particles which the consumer likes by aligning to the corresponding gears through the adjusting button. The gear adjusting structure is compact in structure, the gears are convenient to calibrate, and the production is convenient. After one-time gear calibration in the assembling process, a consumer does not need to repeatedly calibrate the gear every time the gear is used, and the gear calibration device isconvenient to use by the consumer. The invention further relates to a gear calibration method.

Description

technical field [0001] The invention relates to a gear adjustment structure of a hand-operated coffee grinder, and also relates to a gear calibration method of the adjustment structure, which belongs to the technical field of coffee appliance manufacturing. Background technique [0002] In the hand-operated coffee grinder in the prior art, the adjustment of the thickness of the coffee powder is realized by rotating the adjustment knob. However, it is not possible to specifically and accurately specify the thickness gear, and the user needs to judge the thickness of the coffee powder based on experience, and then perform more It is very inconvenient to use multiple adjustments. There are also some more advanced grinders that can specify the thickness gear, but the structure is complicated, the manufacturing precision is high, and the cost is high. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a gear adjustment s...
