Description

[Technical Field]

[0001] The present invention relates to the technical field of grinding machines, and in particular to grinding devices. [Background technology]

[0002] In recent years, coffee culture has gradually become popular, and more and more people are seeking high-quality coffee. As one of the core technologies for coffee production, handheld coffee grinders are increasingly favored by coffee lovers. The coffee grinder can not only grind coffee beans, but also grind seasonings such as pepper, pepper, and salt, which can enrich the texture of food.

[0003] Generally, a grinding machine includes a male grinding head, a female grinding head, and an adjusting rod. The adjusting rod is located in the central hole of the male grinding head. When grinding, the male grinding head and the female grinding head rotate relative to each other (either the male grinding head rotates or the female grinding head rotates). When adjusting the grinding thickness, the adjusting member can be used to move the male grinding head up and down along the adjusting rod to achieve the adjustment. A restoring member must be installed on the outer periphery of the adjusting rod to return the male grinding head.

[0004] The utility model bearing Patent Number 202320982666.6 discloses an adjustment mechanism for a grinder and a grinder, the adjustment mechanism including a position limiting assembly and an adjustment assembly, the adjustment assembly being movably connected to the outside of the position limiting assembly, wherein an inner wall of the position limiting assembly is provided with a receiving groove, an outer grinding head is disposed in the receiving groove, an adjustment groove is provided on the outer wall of the position limiting assembly, and an adjustment bump is provided on the inner wall of the adjustment assembly that engages with the adjustment groove, and when the adjustment assembly drives the adjustment bump to rotate, the position limiting assembly can drive the outer grinding head to move axially, thereby changing the size of the grinding path. Although the size of the grinding path can be changed by the adjustment assembly driving the rotation of the adjustment bump, the span of the grinding path adjusted using this method is relatively large, making it difficult to finely adjust the grain size of the ground material, making it difficult for users to obtain a relatively satisfactory grain size.

[0022] In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described in detail, clearly and completely below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are only for the purpose of interpreting the present invention, and are not intended to limit the present invention.

[0023] As should be understood by those skilled in the art, in the present invention, the directions or positional relationships indicated by terms such as "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are based on the directions or positional relationships shown in the accompanying drawings, and are intended merely to facilitate and simplify the description of the present utility model, and do not indicate or imply that the relevant devices or components have a specific orientation or should be constructed or operated in a specific direction, and therefore, the above terms should not be construed as limiting the present utility model.

[0024] 1, 2, 10 and 11, one embodiment of the present invention provides a grinding device, the grinding device including a housing 1 and an adjustment mechanism, a male grinding head 200 and a female grinding head 100 are provided in the housing 1, and a grinding passage is provided between the male grinding head 200 and the female grinding head 100, the adjustment mechanism includes a first adjustment assembly 2 and a second adjustment assembly, the first adjustment assembly 2 has a substantially annular structure and is connected to the housing 1, the second adjustment assembly includes a first adjustment sleeve 3 and a second adjustment sleeve 4 that are threadedly engaged with each other, when the first adjustment assembly 2 is rotated, the first adjustment sleeve 3 also rotates accordingly, the rotation of the first adjustment sleeve 3 drives the second adjustment sleeve 4 to move up and down, and the up and down movement of the second adjustment sleeve 4 changes the size of the grinding passage. When the first adjusting assembly 2 is rotated, the first adjusting sleeve 3 also rotates, and the rotation of the first adjusting sleeve 3 drives the up and down movement of the second adjusting sleeve 4. Because the first adjusting sleeve 3 and the second adjusting sleeve 4 are screwed together, the range of up and down movement of the second adjusting sleeve 4 is relatively small, and therefore the change in the size of the grinding passage is also relatively small. Thus, the particle size of the ground material can be easily and accurately controlled, and the user can relatively easily obtain the desired particle size. In addition, because the first adjusting sleeve 3 and the second adjusting sleeve 4 are screwed together, the first adjusting sleeve 3 and the second adjusting sleeve 4 have a self-locking function, which makes the operation of the grinding device more stable and reliable when grinding. When the second adjusting sleeve 4 is held in a constant state, the size of the grinding passage is well fixed, and therefore the particle size of the ground material is relatively uniform. It should be noted that the adjustment mechanism can be used in manual grinding machines (as shown in Figures 1, 2 and 11) and in power grinding machines (as shown in Figure 19), where the power grinding machine is provided with a motor 300 that drives the male grinding head 200 or the female grinding head 100 to rotate. [Example]

[0025] As shown in FIGS. 1 to 9 , a first connecting sleeve 6 is connected to the upper part of the housing 1, and the first connecting sleeve 6 is installed above the first adjusting sleeve 3. A material supply assembly 8 is connected to the first connecting sleeve 6, and the material to be ground enters the grinding passage from the material supply assembly 8 to be ground. Specifically, the material supply assembly 8 has a bottle or tank shape, and an external thread is provided on the outer peripheral wall of the material supply assembly 8, and an internal thread is provided on the inner peripheral wall of the first connecting sleeve 6, and the material supply assembly 8 is screwed onto the first connecting sleeve 6. A stepped surface 54 is provided on the first connecting sleeve 6, and the opening of the material supply assembly 8 abuts against the stepped surface 54. The provision of the stepped surface 54 blocks direct contact between the housing 1 and the material to be ground, preventing the material to be ground from adhering to the housing 1 or leaking from the connection point of the housing 1. The second adjusting sleeve 4 includes a connecting portion 41 and a receiving portion 42, the connecting portion 41 and the receiving portion 42 being integrally molded, the size of the receiving portion 42 being larger than the size of the connecting portion 41, the cross section of the second adjusting sleeve 4 presents a "convex"-shaped structure, the connecting portion 41 is installed above the receiving portion 42, the outer peripheral wall of the connecting portion 41 is provided with a male thread, the first adjusting sleeve 3 is provided with a female thread, the first adjusting sleeve 3 and the second adjusting sleeve 4 are screwed together by the female thread and the male thread, and the receiving portion 42 is fitted to the outside of the female grinding head 100.

[0026] Furthermore, a flow guide surface 43 is provided on the upper side of the inner peripheral wall of the connecting portion 41, and is used to guide the material to be ground from the material supply assembly 8 into the grinding passage. The upper side of the outer peripheral wall of the connecting portion 41 is in close contact with the lower side of the first connecting sleeve 6, preventing the material to be ground from falling into the gap between the connecting portion 41 and the first connecting sleeve 6. At least one first position limiting groove 21 is provided on the inner wall of the first adjusting assembly 2, and at least one first position limiting protrusion 31 is provided on the outer wall of the first adjusting sleeve 3. Preferably, the first position limiting protrusion 31 has a square bump structure, and the first position limiting groove 21 corresponds to the position of the first position limiting protrusion 31, and the first position limiting protrusion 31 is located within the first position limiting groove 21, thereby rotating the first adjusting assembly 2 and causing the first adjusting sleeve 3 to rotate accordingly.

[0027] The housing 1 further includes a support frame 5, which is disposed between the first adjusting assembly 2 and the first adjusting sleeve 3 and has an openwork structure, and the first adjusting assembly 2 and the first adjusting sleeve 3 are connected at the openwork structure. The housing 1 has an openwork cylindrical structure, and a plurality of first connecting grooves 11 are provided on the inner peripheral wall of the housing 1, and a plurality of connecting protrusions 51 are provided on the outer peripheral wall of the support frame 5, and the first connecting grooves 11 engage with the connecting protrusions 51 to connect the housing 1 to the support frame 5. The inner peripheral wall of the support frame 5 is provided with a first positioning protrusion 52 and a second positioning protrusion 53. The second positioning protrusion 53 has an annular protrusion structure, and the first positioning protrusion 52 is located above the second positioning protrusion 53. The outer peripheral wall of the first connecting sleeve 6 is provided with an attachment groove 61, and the first positioning protrusion 52 is attached to the attachment groove 61. The second positioning protrusion 53 is located between the first connecting sleeve 6 and the first adjusting sleeve 3. After the support frame 5 is connected to the first connecting sleeve 6, the upper surface of the second positioning protrusion 53 contacts the lower end of the first connecting sleeve 6. The installation of the support frame 5 on the one hand makes the structure of the grinding device more stable, and on the other hand, the support frame 5 is located inside the housing 1, which improves the sealing of the grinding device and prevents material leakage.

[0028] Preferably, the second adjusting assembly further includes a third adjusting sleeve 30, which is disposed below and connected to the second adjusting sleeve 4, and which moves upward to move the third adjusting sleeve 30 upward, with the lower end of the knife grinding head 100 contacting the upper edge of the third adjusting sleeve 30. Specifically, the outer peripheral wall of the third adjusting sleeve 30 is provided with at least one first locking protrusion, and the inner peripheral wall of the receiving portion 42 is provided with at least one first locking groove, which engages with the first locking protrusion to lock the third adjusting sleeve 30 to the second adjusting sleeve 4, and the up and down movement of the second adjusting sleeve 4 drives the up and down movement of the third adjusting sleeve 30. The upper end of the female grinding head 100 contacts the lower end of the connecting part 41, and the lower end of the female grinding head 100 contacts the upper edge of the third adjustable sleeve 30. This means that the female grinding head 100 is disposed between the two and moves up and down along with the up and down movement of the third adjustable sleeve 30. During this process, the male grinding head 200 does not move up and down accordingly. The up and down movement of the female grinding head 100 changes the grinding path, thereby changing the size of the ground material particles.

[0029] Furthermore, a cover 40 or a material receiving assembly can be connected below the third adjusting sleeve 30, and the cover 40 and the material receiving assembly can be isolated from the outside to prevent external foreign objects from entering the inside of the grinding device.

[0030] In particular, a second connecting sleeve 7 is further provided between the first adjusting assembly 2 and the receiving portion 42, a second locking protrusion 71 is provided on the inner peripheral wall of the second connecting sleeve 7, and a second locking groove 44 is provided at a corresponding position on the outer peripheral wall of the receiving portion 42, and the second locking protrusion 71 is located within the second locking groove 44. The second locking protrusion 71 serves to restrict position, and as the second connecting sleeve 7 moves up and down, the second locking groove 44 and the second locking protrusion 71 move up and down relative to each other. As can be seen, as the second connecting sleeve 7 moves up and down, the second locking protrusion 71 is always located within the second locking groove 44.

[0031] 8 and 9, the second connecting sleeve 7 has a groove on its outer circumferential wall, an expandable bead 72 in the groove, and a plurality of grooves 22 on its inner circumferential wall. When the first adjusting assembly 2 is rotated, the expandable bead 72 moves from one groove 22 to another, generating a clicking sound during this process. That is, when the first adjusting assembly 2 is rotated, the second connecting sleeve 7 moves up and down, changing the grinding path accordingly. At the same time, the expandable bead 72 generates a clicking sound, allowing the user to adjust the shift and obtain the appropriate grind size. Preferably, an opening 73 is provided above the groove. This allows the expandable bead 72 to be constantly ejected into the groove as it moves from one groove 22 to another groove 22. This requires the groove to have a certain degree of elastic deformation. The provision of the opening 73 provides the groove with a certain degree of elastic deformation. [Example]

[0032] As shown in Figures 10 to 18, a third connecting sleeve 9 is provided in the housing 1. The third connecting sleeve 9 is engaged with the housing 1. The third connecting sleeve 9 is provided with an arc-shaped flow guide surface 43, allowing the grinding object to smoothly enter the grinding passage. The second adjusting sleeve 4 includes a connecting portion 41 and a receiving portion 42, which are integrally molded. The receiving portion 42 is larger than the connecting portion 41. The cross section of the second adjusting sleeve 4 has a convex shape. The connecting portion 41 is located above the receiving portion 42. The outer peripheral wall of the connecting portion 41 is provided with a male thread. The first adjusting sleeve 3 is provided with a female thread. The first adjusting sleeve 3 and the second adjusting sleeve 4 are threadedly engaged with each other via the male thread. The receiving portion 42 is fitted to the outside of the female grinding head 100, and the connecting portion 41 is located above the receiving portion 42. The third connecting sleeve 9 is provided with a second connecting groove 91, the opening of which faces downward, and the upper ends of the first adjusting sleeve 3 and the second adjusting sleeve 4 are both located within the second connecting groove 91. After the third connecting sleeve 9 is connected to the second adjusting sleeve 4, the outer peripheral wall of the lower end of the third connecting sleeve 9 and the inner peripheral wall of the connecting portion 41 are tightly fitted together, so that the object to be ground will not leak from the connection point between the two.

[0033] The grinding device further includes a support frame 5 and a material receiving hopper 10, an upper end of the support frame 5 is locked to the third connecting sleeve 9, and a lower end of the support frame 5 is connected to the material receiving hopper 10 by a screw. The support frame 5 is at least partially installed between the housing 1 and the second adjusting sleeve 4, which enhances the sealing and structural strength of the grinding device.

[0034] 14 and 18, the inner wall of the first adjusting assembly 2 is provided with at least one first position limiting groove 21, and the outer wall of the first adjusting sleeve 3 is provided with at least one first position limiting protrusion 31. The first position limiting groove 21 corresponds to the position of the first position limiting protrusion 31, and the first position limiting protrusion 31 is located within the first position limiting groove 21, thereby rotating the first adjusting assembly 2 and the first adjusting sleeve 3. The first adjusting sleeve 3 and the second adjusting sleeve 4 are threaded together with internal and external threads, so that when the first adjusting sleeve 3 rotates, the second adjusting sleeve 4 moves up and down, changing the size of the grinding passage. The first adjusting sleeve 3 and the second adjusting sleeve 4 are threaded together with internal and external threads, allowing for fine adjustment of the size of the grinding passage. As can be seen, the support frame 5 is provided with an openwork structure, and the first adjusting assembly 2 and the first adjusting sleeve 3 are connected at the openwork structure.

[0035] 16 and 17, the accommodating section 42 has a plurality of third position limiting protrusions 45 arranged vertically on its outer peripheral wall, and the support frame 5 has a plurality of third position limiting grooves 55 arranged vertically on its inner peripheral wall. The third position limiting protrusions 45 correspond one-to-one in number and position to the third position limiting grooves 55. When the first adjusting assembly 2 is rotated, the second adjusting sleeve 4 moves up and down. During the up and down movement of the second adjusting sleeve 4, the third position limiting protrusions 45 move up and down along the third position limiting grooves 55. The third position limiting protrusions 45 engage with the third position limiting grooves 55, thereby playing a role in limiting the position of the second adjusting sleeve 4 during its up and down movement and preventing it from shifting, thereby making the operation of the grinding device more stable and reliable.

[0036] Furthermore, the support frame 5 is provided with a stepped surface 54, and the lower edge of the first adjusting assembly 2 is located on the stepped surface 54. A receiving hole is further provided on the outer peripheral wall of the support frame 5, and the receiving hole is located above the stepped surface 54. An expandable bead 72 is provided in the receiving hole, and a plurality of grooves 22 are provided on the inner peripheral wall of the first adjusting assembly 2. When the first adjusting assembly 2 is rotated, the expandable bead 72 is transformed from one groove 22 to another different groove 22, and in this process, a "click" sound is emitted. That is, when the first adjusting assembly 2 is rotated, the second connecting sleeve 7 moves up and down, and the grinding passage changes accordingly. At the same time, the expandable bead 72 emits a "click" sound, which allows the user to adjust the different "shifts" to obtain the appropriate grinding particle size.

[0037] The second adjusting assembly further includes a third adjusting sleeve 30, which is disposed below and connected to the second adjusting sleeve 4. The second adjusting sleeve 4 moves upward to move the third adjusting sleeve 30 upward, and the lower end of the knife grinding head 100 contacts the upper edge of the third adjusting sleeve 30. Specifically, an annular protrusion is provided on the outer peripheral wall of the third adjusting sleeve 30, and an annular groove 22 is provided on the inner peripheral wall of the receiving portion 42. The annular protrusion and the annular groove 22 engage with each other to lock the third adjusting sleeve 30 and the second adjusting sleeve 4, and the up and down movement of the second adjusting sleeve 4 drives the up and down movement of the third adjusting sleeve 30. The upper end of the female grinding head 100 contacts the lower end of the connecting part 41, and the lower end of the female grinding head 100 contacts the upper edge of the third adjustable sleeve 30. This means that the female grinding head 100 is disposed between the two and moves up and down along with the up and down movement of the third adjustable sleeve 30. During this process, the male grinding head 200 does not move up and down accordingly. The up and down movement of the female grinding head 100 changes the grinding path, thereby changing the size of the ground material particles.
