Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a coffee machine grinding speed adjustment structure. Background Technology

[0002] In the field of coffee machine technology, the grind setting adjustment structure is the core component for controlling the coarseness of coffee powder, and its design directly affects the user experience and equipment performance.

[0003] Currently, most coffee machine grinding systems on the market use the following two speed adjustment schemes:

[0004] Multi-part linkage structure: Gear adjustment is achieved through the combination of multiple parts such as gear sets, springs, and positioning pins. For example, some models use a spiral adjusting ring with a limit slot design, requiring the rotation of an external knob to drive the internal transmission mechanism, thereby adjusting the blade spacing. Although this type of structure can achieve multi-gear adjustment, it suffers from a large number of parts and complex assembly processes, resulting in high production costs and an increased failure rate.

[0005] No adjustable speed setting: Some low-end models omit the adjustable speed setting function, with a fixed blade spacing, failing to meet users' personalized needs for coffee grind size. While this design simplifies the structure, it sacrifices functionality and is difficult to adapt to market demands. Summary of the Invention

[0006] The purpose of this invention is to provide a coffee machine grinding speed adjustment structure to solve the above-mentioned problems.

[0007] According to one aspect of this utility model, a coffee machine grinding speed adjustment structure is provided, comprising: a grinding bracket, a lower blade disk rotatably connected to the grinding bracket, an outer adjusting wheel rotatably disposed above the lower blade disk, an inner adjusting wheel rotatably connected to the inner side of the outer adjusting wheel, a threaded structure corresponding to the outer adjusting wheel and the inner adjusting wheel, a plurality of guide blocks disposed vertically at the bottom of the inner adjusting wheel, a guide groove provided on the grinding bracket corresponding to the guide blocks, an upper blade disk cooperating with the lower blade disk disposed in the middle of the inner adjusting wheel, an adjusting rod movably disposed on one side of the grinding bracket, the adjusting rod being provided with a first tooth, a second tooth being provided on the outer side of the outer adjusting wheel, the first tooth meshing with the second tooth.

[0008] In some embodiments, the upper edge of the grinding support is provided with a plurality of limiting plates for defining the position of the outer adjusting wheel.

[0009] In some embodiments, a bean hopper support is provided above the grinding support, a positioning hole is provided at the bottom of the bean hopper support, a positioning post is provided on one side of the grinding support, and the adjusting rod is rotatably connected between the positioning hole and the positioning post.

[0010] In some embodiments, the lower part of the bean hopper support is provided with a bean inlet, and a connecting sleeve is fitted between the bean inlet and the inner adjusting wheel.

[0011] In some embodiments, the upper part of the inner adjusting wheel is provided with a mounting plate, and the lower part of the connecting sleeve is provided with a groove corresponding to the mounting plate.

[0012] In some embodiments, the upper part of the connecting sleeve is provided with elastic pleats.

[0013] In some embodiments, the connecting sleeve is made of rubber or silicone.

[0014] In some embodiments, the top of the adjusting rod is provided with a hexagonal screw hole.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This application achieves multi-level adjustment by adding an adjustment rod to drive the upper blade disc to move in conjunction with toothed transmission. Compared with the traditional multi-part linkage structure, the number of parts is significantly reduced, which significantly reduces production costs and assembly complexity. The simplified adjustment structure occupies less space, which is conducive to the compact design of the internal layout of the coffee machine, freeing up more space for other functional modules and supporting the development of products towards lightweight and miniaturization.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figures 1 to 4This application provides a coffee machine grinder setting adjustment structure, including: a grinder support 1, a lower blade 2 rotatably connected to the grinder support 1, an outer adjusting wheel 3 rotatably disposed above the lower blade 2, an inner adjusting wheel 4 rotatably connected to the inner side of the outer adjusting wheel 3, a threaded structure 5 corresponding to the outer adjusting wheel 3 and the inner adjusting wheel 4, a plurality of guide blocks 6 vertically disposed at the bottom of the inner adjusting wheel 4, a guide groove 7 corresponding to the guide blocks 6 in the grinder support 1, an upper blade 8 cooperating with the lower blade 2 disposed in the middle of the inner adjusting wheel 4, an adjusting rod 9 movably disposed on one side of the grinder support 1, the adjusting rod 9 being provided with a first tooth 10, a second tooth 11 being provided on the outer side of the outer adjusting wheel 3, the first tooth 10 and the second tooth 11 meshing; the inner adjusting wheel 4 always moves vertically when the guide blocks 6 and the guide groove 7 are engaged.

[0023] In some embodiments, the upper edge of the grinding support 1 is provided with a plurality of limiting plates 12 for limiting the position of the outer adjusting wheel 3, and the limiting plates 12 can prevent the outer adjusting wheel 3 from falling off or shifting.

[0024] In some embodiments, a bean hopper support 13 is provided above the grinding support 1, a positioning hole 14 is provided at the bottom of the bean hopper support 13, a positioning post 15 is provided on one side of the grinding support 1, and an adjusting rod 9 is rotatably connected between the positioning hole 14 and the positioning post 15.

[0025] In some embodiments, the lower part of the bean hopper support 13 is provided with a bean inlet, and a connecting sleeve 16 is sleeved between the bean inlet and the inner adjusting wheel 4 to ensure that no powder is leaked when the upper cutter disc 8 rises or falls.

[0026] In some embodiments, the upper part of the inner adjusting wheel 4 is provided with a mounting plate 17, and the lower part of the connecting sleeve 16 is provided with a retaining groove corresponding to the mounting plate 17 to prevent the connecting sleeve 16 from falling off.
