Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, and in particular to grinding devices and coffee machines. Background Technology

[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. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-pinch device and a vending machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the first aspect of this utility model provides a grinding device applied to a coffee machine, comprising a body, wherein the body is provided with an adjusting worm gear for adjusting the grinding fineness; the grinding device further includes an adjusting component, the adjusting component comprising:

[0007] Mounting base; the mounting base is mounted on the body;

[0008] A worm gear component; the worm gear component is mounted on the mounting base; the mounting base is mounted on the body; the worm gear component includes a worm portion and a drive portion, the worm portion being connected to an adjusting worm wheel on the grinder;

[0009] A limiting component; the limiting component is sleeved on the driving part, and the limiting component rotates synchronously with the worm gear part;

[0010] The mounting base has a resistance part on its inner periphery. The limiting member cooperates with the resistance part, so that the driving part needs to overcome the resistance generated between the limiting member and the resistance part before it can rotate.

[0011] Furthermore, the resistance section consists of spaced-apart protrusions.

[0012] Furthermore, the limiting element includes;

[0013] Mounting part; the mounting part is sleeved on the driving part;

[0014] A limiting part; the limiting part is connected to the mounting part; the limiting part is engaged between two adjacent protrusions; the limiting member needs to overcome the resistance between the limiting part and the protrusions in order to rotate the limiting member.

[0015] Furthermore, the limiting member also includes an elastic portion; the elastic portion is connected to the mounting portion; the limiting portion is mounted on the outer wall surface of the elastic portion; and an arc-shaped through groove is formed between the elastic portion and the mounting portion.

[0016] Furthermore, the elastic part is provided with a deformation part that bends into the arc-shaped through groove.

[0017] Furthermore, there are two deformable parts, and the limiting part is located between the two deformable parts.

[0018] Furthermore, a knob is installed at the end of the drive unit.

[0019] Furthermore, the knob is provided with anti-slip texture.

[0020] Furthermore, the knob is provided with a marking section; the marking section is used to display the coarseness of the bean grinder corresponding to the rotation direction of the knob.

[0021] Secondly, this utility model also provides a coffee machine, including a grinding device.

[0022] Compared with the prior art, this utility model brings the following technical effects:

[0023] In this grinding device, when the user needs to adjust the coarseness of the coffee bean powder, the drive unit needs to be manually rotated to rotate the worm gear, which in turn drives the worm wheel to rotate, thus adjusting the coarseness of the coffee bean powder. It should be noted that adjusting the coarseness of the coffee bean powder by rotating the worm wheel is a conventional technique in the art and will not be described in detail here. After the user has adjusted it, the resistance between the limiting component and the resistance component prevents the worm wheel from rotating during operation. It should be specifically noted that while the resistance between the limiting component and the resistance component prevents the worm wheel from rotating, an adult can still rotate the worm gear normally. Therefore, the design of the limiting component and the resistance component effectively prevents the worm wheel from rotating during operation. Attached Figure Description

[0036] Example 1

[0037] Please refer to Figures 1-4 A grinding device, applied to a coffee machine, includes a body 1, on which an adjusting worm gear 101 is provided for adjusting the grinding fineness; characterized in that: the grinding device further includes an adjusting component, the adjusting component comprising:

[0038] Mounting base 2; the mounting base 2 is mounted on the body 1;

[0039] Worm gear 3; the worm gear 3 is mounted on the mounting base 2; the mounting base 2 is mounted on the body 1; the worm gear 3 includes a worm portion 301 and a drive portion 302, the worm portion 301 is connected to the adjusting worm wheel 101 on the grinder;

[0040] Limiting member 4; The limiting member 4 is sleeved on the driving part 302, and the limiting member 4 rotates synchronously with the worm gear part 301;

[0041] The mounting base 2 has a resistance part 201 on its inner periphery. The limiting member 4 cooperates with the resistance part 201, so that the driving part 302 needs to overcome the resistance generated between the limiting member 4 and the resistance part 201 before it can rotate.

[0042] In this embodiment, when the user needs to adjust the coarseness of the coffee bean powder ground by the grinder, the drive unit 302 needs to be manually rotated to rotate the worm gear 3, thereby driving the worm wheel 101 to rotate, thus adjusting the coarseness of the coffee bean powder ground by the grinder. It should be noted that adjusting the coarseness of the coffee bean powder ground by rotating the worm wheel 101 is a conventional technique in the art and will not be described in detail here. After the user has adjusted it, the resistance between the limiting member 4 and the resistance member 201 can prevent the worm wheel 101 from rotating when the grinder is working. It should be noted that the resistance between the limiting member 4 and the resistance member 201 can prevent the worm wheel 101 from rotating, but an adult can rotate the worm gear 3 normally. Therefore, the design of the limiting member 4 and the resistance member 201 can effectively prevent the worm wheel 101 from rotating when the grinder is working.

[0043] Furthermore, the resistance section 201 consists of spaced-apart protrusions.

[0044] Furthermore, the limiting element 4 includes;

[0045] Mounting part 401; the mounting part 401 is sleeved on the driving part 302;

[0046] Limiting part 402; the limiting part 402 is connected to the mounting part 401; the limiting part 402 is engaged between two adjacent protrusions; the limiting member 4 needs to overcome the resistance between the limiting part 402 and the protrusions in order to rotate the limiting member 4.

[0047] Furthermore, the limiting member 4 also includes an elastic part 403; the elastic part 403 is connected to the mounting part 401; the limiting part 402 is mounted on the outer wall surface of the elastic part 403; an arc-shaped through groove 404 is formed between the elastic part 403 and the mounting part 401.

[0048] Furthermore, the elastic part 403 is provided with a deformation part 405 that bends into the arc-shaped through groove 404.

[0049] Furthermore, there are two deformable parts 405, and the limiting part 402 is located between the two deformable parts 405.

[0050] Furthermore, the adjustment assembly also includes a limiting member, which is installed in the mounting base 2 and fixedly connected to the mounting base 2. The limiting member has a first end face, and the worm gear 3 has a second end face. The first end face and the second end face are in contact. The limiting member is used to restrict the worm gear 3 from moving axially.

[0051] In this embodiment, the limiting part 402 is precisely positioned between two adjacent protrusions, the cross-section of which is arc-shaped; the driving part 302 is a hexahedral prism. In other embodiments, the driving part 302 can also be a columnar body of other shapes, but a cylinder cannot be used. The mounting part 401 has a through hole that matches the limiting part 402. Therefore, when the user rotates the driving part 302, the limiting member 4 will rotate along with the driving part 302. Since the limiting part 402 in the limiting member 4 is positioned between two adjacent protrusions, the user needs to overcome the resistance between the limiting part 402 and the protrusions to rotate the driving part 302. Two deformation parts 405 are provided on the limiting member 4. Therefore, when the user rotates the driving part 302, the deformation parts 405 will deform, which not only makes it easier for the user to rotate the driving part 302, but also effectively reduces the frictional wear between the limiting part 402 and the protrusions.

[0052] Furthermore, a knob 5 is installed at the end of the drive unit 302.

[0053] Furthermore, the knob 5 is provided with anti-slip texture.

[0054] Furthermore, the knob 5 is provided with an indicator 501; the indicator 501 is used to display the coarseness of the bean grinder corresponding to the rotation direction of the knob 5.

[0055] In this embodiment, since the drive unit 302 is relatively thin, it is quite strenuous for the user to directly rotate it. Therefore, a knob 5 is fixedly connected to the end of the drive unit 302, making it easier for the user to rotate the drive unit 302. Additionally, anti-slip textures are provided on the circumferential surface of the knob 5 to further facilitate rotation. Furthermore, a marking section 501 is provided on the axial surface of the knob 5, allowing the user to clearly see which direction the rotation produces coarser and finer coffee beans. Of course, in some grinding devices, more precise scale markings are also provided at the worm gear 101.
