Description

Technical Field

[0001] The present disclosure relates to the technical field of grinders, and in particular to a grinding device. Background Art

[0002] In recent years, coffee culture has gradually become popular, and more and more people have begun to pursue high-quality coffee. As one of the core technologies for coffee making, handheld grinders are increasingly favored by coffee experts. Grinders can not only grind coffee, but also grind peppercorns, pepper, salt and other condiments to enrich the taste of food.

[0003] Usually, the grinder includes a male grinding head, a female grinding head and an adjusting rod. The adjusting rod is located in the hole in the center of the male grinding head. During 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 coarseness of the grinding, the adjustment is achieved by moving the male grinding head up and down along the adjusting rod through the adjusting piece. A reset piece needs to be set on the outer periphery of the adjusting rod for resetting the male grinding head.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0043] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0044] Please see Figure 1 , Figure 2 , Fig.10 and Fig.11As shown, an embodiment of the present disclosure provides a grinding device, including a housing 1 and an adjustment mechanism, wherein a male grinding head 200 and a female grinding head 100 are arranged in the housing 1, and a grinding channel is arranged between the male grinding head 200 and the female grinding head 100, and the adjustment mechanism includes a first adjustment component 2 and a second adjustment component, wherein the first adjustment component 2 is a roughly annular structure connected to the housing 1, and the second adjustment component includes two first adjustment sleeves 3 and second adjustment sleeves 4 that are screwed together, and the first adjustment component 2 is rotated, and the first adjustment sleeve 3 is also rotated accordingly, and the rotation of the first adjustment sleeve 3 drives the up and down movement of the second adjustment sleeve 4, and the up and down movement of the second adjustment sleeve 4 changes the size of the grinding channel. When the first adjustment component 2 is rotated, the first adjustment sleeve 3 is also rotated accordingly, and the rotation of the first adjustment sleeve 3 drives the up and down movement of the second adjustment sleeve 4. Since the first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together, the range of up and down movement of the second adjustment sleeve 4 is relatively fine, so that the change in the size of the grinding channel is also fine, so that the particle size of the grinding object can be conveniently and accurately controlled, and the user can easily obtain the desired particle size. In addition, since the first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together, the first adjustment sleeve 3 and the second adjustment sleeve 4 have a self-locking function, so that the grinding device works more stably and reliably during grinding. When the second adjustment sleeve 4 is kept in a certain state, the size of the grinding channel is well fixed, so that the particle size of the grinding object is relatively uniform. It should be noted that the adjustment mechanism can be used for manual grinding devices (such as Figure 1 , Figure 2 and Fig.11 as shown) and electric grinding devices (as Fig.19 As shown in the figure, a motor 300 is provided in the electric grinding device, and the male grinding head 200 or the female grinding head 100 is driven to rotate by the motor 300.

[0045] Example 1

[0046] Please see Figures 1 to 9As shown, the first connecting sleeve 6 is connected to the upper part of the housing 1, and the first connecting sleeve 6 is arranged above the first adjusting sleeve 3. The first connecting sleeve 6 is connected to the feeding assembly 8, and the material to be ground enters the grinding channel through the feeding assembly 8 for grinding. Specifically, the feeding assembly 8 is in the shape of a bottle or a can, and the outer peripheral wall of the feeding assembly 8 is provided with an external thread, and the inner peripheral wall of the first connecting sleeve 6 is provided with an internal thread, and the feeding assembly 8 is screwed with the first connecting sleeve 6. The first connecting sleeve 6 is provided with a step surface 54, and the opening of the feeding assembly 8 abuts against the step surface 54. The setting of the step surface 54 isolates the housing 1 from direct contact with the material to be ground, and prevents the material to be ground from sticking to the housing 1 or leaking from the connection of the housing 1. The second adjustment sleeve 4 includes a connecting portion 41 and a receiving portion 42, and the connecting portion 41 and the receiving portion 42 are integrally formed. The size of the receiving portion 42 is larger than that of the connecting portion 41. The cross-section of the second adjustment sleeve 4 is a "convex"-shaped structure. The connecting portion 41 is arranged above the receiving portion 42. An external thread is arranged on the outer peripheral wall of the connecting portion 41. The first adjustment sleeve 3 is provided with an internal thread. The first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together through the internal thread and the external thread, and the receiving portion 42 is sleeved on the outside of the female grinding head 100.

[0047] Furthermore, a guide surface 43 is provided above the inner peripheral wall of the connecting portion 41, and the guide surface 43 is used to guide the to-be-ground material coming out of the feed assembly 8 into the grinding channel. The upper part of the outer peripheral wall of the connecting portion 41 is tightly fitted with the lower part of the first connecting sleeve 6 to prevent the to-be-ground material from falling into the gap between the connecting portion 41 and the first connecting sleeve 6. At least one first limiting groove 21 is provided on the inner wall of the first adjusting component 2, and at least one first limiting protrusion 31 is provided on the outer wall of the first adjusting sleeve 3. Preferably, the first limiting protrusion 31 is a square convex block structure, and the positions of the first limiting groove 21 and the first limiting protrusion 31 correspond to each other. The first limiting protrusion 31 is located in the first limiting groove 21, so that when the first adjusting component 2 is rotated, the first adjusting sleeve 3 also rotates.

[0048] Furthermore, it also includes a support frame 5, which is provided between the first adjustment component 2 and the first adjustment sleeve 3, and the support frame 5 is provided with a hollow structure, and the first adjustment component 2 is connected to the first adjustment sleeve 3 at the hollow structure. The shell 1 is a hollow cylindrical structure, and the inner peripheral wall of the shell 1 is provided with a plurality of first connecting grooves 11, and the outer peripheral wall of the support frame 5 is provided with a plurality of connecting protrusions 51, and the first connecting grooves 11 cooperate with the connecting protrusions 51 to connect the shell 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, and the second positioning protrusion 53 is an annular protrusion structure. The first positioning protrusion 52 is arranged above the second positioning protrusion 53, and the outer peripheral wall of the first connecting sleeve 6 is provided with a mounting groove 61, and the first positioning protrusion 52 is installed in the mounting groove 61, and the second positioning protrusion 53 is arranged between the first connecting sleeve 6 and the first adjustment 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 support frame 5 is provided to make the structure of the grinding device more stable on the one hand, and the support frame 5 is located inside the shell 1 on the other hand, so that the sealing performance of the grinding device is better to avoid material leakage.

[0049] Preferably, the second adjustment assembly further includes a third adjustment sleeve 30, which is disposed below the second adjustment sleeve 4 and connected to the second adjustment sleeve 4. The second adjustment sleeve 4 moves upward to drive the third adjustment sleeve 30 to move upward, and the lower end of the female grinding head 100 contacts the upper edge of the third adjustment sleeve 30. Specifically, at least one first clamping protrusion is disposed on the outer peripheral wall of the third adjustment sleeve 30, and at least one first clamping groove is disposed on the inner peripheral wall of the accommodating portion 42. The first clamping protrusion cooperates with the first clamping groove to clamp the third adjustment sleeve 30 with the second adjustment sleeve 4, and the up and down movement of the second adjustment sleeve 4 drives the up and down movement of the third adjustment sleeve 30. The upper end of the female grinding head 100 contacts the lower end of the connecting portion 41, and the upper end of the female grinding head 100 contacts the upper edge of the third adjusting sleeve 30, which is equivalent to the female grinding head 100 being placed between the two and moving up and down with the up and down movement of the third adjusting sleeve 30. During this process, the male grinding head 200 will not move up and down accordingly. The up and down movement of the female grinding head 100 brings about changes in the grinding channel, thereby changing the size of the grinding material particles.

[0050] Furthermore, a sealing cover 40 or a material receiving assembly may be connected to the bottom of the third adjustment sleeve 30, and the sealing cover 40 and the material receiving assembly may be isolated from the outside to prevent foreign matter from entering the grinding device.

[0051] In particular, a second connecting sleeve 7 is further provided between the first adjusting component 2 and the accommodating portion 42, a second positioning protrusion 71 is provided on the inner peripheral wall of the second connecting sleeve 7, a second clamping groove 44 is provided at a corresponding position of the outer peripheral wall of the accommodating portion 42, and the second positioning protrusion 71 is located in the second clamping groove 44. The second clamping protrusion 71 plays a role of limiting, and during the up and down movement of the second connecting sleeve 7, the second clamping groove 44 and the second clamping protrusion 71 move up and down relatively, and it can be understood that during the up and down movement of the second connecting sleeve 7, the second clamping protrusion 71 is always located in the second clamping groove 44.

[0052] Please see Figure 8 and Fig. 9 As shown, it should be noted that the outer peripheral wall of the second connecting sleeve 7 is provided with a receiving groove, and a telescopic bead 72 is provided in the receiving groove, and the inner peripheral wall of the first adjusting component 2 is provided with a plurality of grooves 22. When the first adjusting component 2 is rotated, the telescopic bead 72 changes from one groove 22 to another groove 22. In this process, a "clicking" sound will be emitted, that is, when the first adjusting component 2 is rotated, the second connecting sleeve 7 moves up and down, and the grinding channel changes accordingly. At the same time, the telescopic bead 72 will emit a "clicking" sound, so that the user can adjust different "gears" to obtain a suitable grinding particle size. Preferably, an opening 73 is provided above the receiving groove. This is because the telescopic bead 72 changes from one groove 22 to another groove 22, and will continuously bounce in and out of the receiving groove, which requires the receiving groove to have a certain elastic deformation. The setting of the opening 73 provides a certain elastic deformation amount to the receiving groove.

[0053] Example 2

[0054] like Figures 10 to 18 As shown, a third connecting sleeve 9 is provided in the housing 1, and the third connecting sleeve 9 is snap-fitted with the housing 1. The third connecting sleeve 9 is provided with an arc-shaped guide surface 43, so that the object to be ground can smoothly enter the grinding channel. The second adjustment sleeve 4 includes a connecting portion 41 and a receiving portion 42, and the connecting portion 41 and the receiving portion 42 are integrally formed. The size of the receiving portion 42 is larger than the size of the connecting portion 41. The cross section of the second adjustment sleeve 4 is a "convex"-shaped structure. The connecting portion 41 is arranged above the receiving portion 42, and an external thread is arranged on the outer peripheral wall of the connecting portion 41. The first adjustment sleeve 3 is provided with an internal thread. The first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together through the internal thread and the external thread. The receiving portion 42 is sleeved on the outside of the female grinding head 100, and the connecting portion 41 is arranged above the receiving portion 42. The third connecting sleeve 9 is provided with a second connecting groove 91, the opening of the second connecting groove 91 faces downward, the upper end of the first adjusting sleeve 3 and the upper end of the second adjusting sleeve 4 are both located in the second connecting groove 91, and 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 is tightly fitted with the inner peripheral wall of the connecting part 41, so that the grinding material will not leak from the connection between the two.

[0055] The grinding device further includes a support frame 5 and a material receiving bin 10. The upper end of the support frame 5 is clamped with the third connecting sleeve 9, and the lower end of the support frame 5 is threadedly connected to the material receiving bin 10. The support frame 5 is at least partially disposed between the housing 1 and the second adjustment sleeve 4, thereby enhancing the sealing and structural strength of the grinding device.

[0056] For further information, see Fig.14 and Fig.18 As shown, at least one first limiting groove 21 is provided on the inner wall of the first adjustment component 2, and at least one first limiting protrusion 31 is provided on the outer wall of the first adjustment sleeve 3. The positions of the first limiting groove 21 and the first limiting protrusion 31 correspond to each other, and the first limiting protrusion 31 is located in the first limiting groove 21, so that when the first adjustment component 2 is rotated, the first adjustment sleeve 3 also rotates. Since the first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together through the internal thread and the external thread, when the first adjustment sleeve 3 is rotated, the second adjustment sleeve 4 moves up and down to change the size of the grinding channel. It is precisely because the first adjustment sleeve 3 and the second adjustment sleeve 4 are screwed together through the internal thread and the external thread that the size of the grinding channel can be finely adjusted. It can be understood that the support frame 5 is provided with a hollow structure, and the first adjustment component 2 is connected to the first adjustment sleeve 3 at the hollow structure.

[0057] In particular, see Fig.16 and Fig.17 As shown, a plurality of vertically arranged third limiting protrusions 45 are provided on the outer peripheral wall of the accommodating portion 42, and a plurality of vertically arranged third limiting grooves 55 are provided on the inner peripheral wall of the supporting frame 5. The number and position of the third limiting protrusions 45 and the third limiting grooves 55 correspond one to one. By rotating the first adjusting component 2, the second adjusting sleeve 4 moves up and down. During the up and down movement of the second adjusting sleeve 4, the third limiting protrusion 45 moves up and down along the third limiting grooves 55. The third limiting protrusion 45 cooperates with the third limiting grooves 55 to play a limiting role during the up and down movement of the second adjusting sleeve 4, thereby preventing the second adjusting sleeve 4 from being offset, thereby making the grinding device work more stably and reliably.

[0058] Furthermore, the support frame 5 is provided with a step surface 54, the lower edge of the first adjustment component 2 is located on the step surface 54, the outer peripheral wall of the support frame 5 is also provided with a receiving hole, the receiving hole is provided above the step surface 54, a telescopic bead 72 is provided in the receiving hole, and the inner peripheral wall of the first adjustment component 2 is provided with a plurality of grooves 22. When the first adjustment component 2 is rotated, the telescopic bead 72 is changed from one groove 22 to another groove 22, and in this process, a "clicking" sound is emitted, that is, when the first adjustment component 2 is rotated, the second connecting sleeve 7 moves up and down, and the grinding channel changes accordingly, and the telescopic bead 72 emits a "clicking" sound, so that the user can adjust different "gears" to obtain a suitable grinding particle size.

[0059] Furthermore, the second adjustment assembly further includes a third adjustment sleeve 30, which is disposed below the second adjustment sleeve 4 and connected to the second adjustment sleeve 4. The second adjustment sleeve 4 moves upward to drive the third adjustment sleeve 30 to move upward, and the lower end of the female grinding head 100 contacts the upper edge of the third adjustment sleeve 30. Specifically, an annular protrusion is disposed on the outer peripheral wall of the third adjustment sleeve 30, and an annular groove 22 is disposed on the inner peripheral wall of the accommodating portion 42. The annular protrusion cooperates with the annular groove 22 to clamp the third adjustment sleeve 30 with the second adjustment sleeve 4, and the up and down movement of the second adjustment sleeve 4 drives the up and down movement of the third adjustment sleeve 30. The upper end of the female grinding head 100 contacts the lower end of the connecting portion 41, and the upper end of the female grinding head 100 contacts the upper edge of the third adjusting sleeve 30, which is equivalent to the female grinding head 100 being placed between the two and moving up and down with the up and down movement of the third adjusting sleeve 30. During this process, the male grinding head 200 will not move up and down accordingly. The up and down movement of the female grinding head 100 brings about changes in the grinding channel, thereby changing the size of the grinding material particles.

[0060] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas.
