Description

Technical Field

[0001] The embodiments of this utility model relate to a coffee grinder, and specifically design a grinder grinding degree adjustment component, a main body housing, and a coffee grinder. Background Technology

[0002] Portable coffee grinders, as portable devices that grind coffee beans into coffee powder, are small in size and easy to carry, allowing users to enjoy freshly ground coffee anytime, anywhere. However, the inventors discovered that some adjustment components are ring-shaped and are fitted onto the grinder's housing. In use, the grind setting is usually adjusted by rotating the adjustment component. However, because the current adjustment components lack directional control, the installation position of the adjustment components on the housing cannot be uniform during the assembly of the grinder. This results in a slight error between the scale on the adjustment ring and the markings on the housing when adjusting the grind setting, thus affecting the accuracy of the adjustment component in adjusting the grind setting. Utility Model Content

[0003] The purpose of this utility model is to design a grind adjustment component, a main housing, and a grinder for a coffee grinder, which can ensure the uniqueness of the installation position of the adjustment component on the housing of the coffee grinder, thereby improving the accuracy of the adjustment component when grinding coffee beans in the coffee grinder assembly.

[0004] To achieve the above objectives, embodiments of this utility model provide a grind adjustment component for a coffee grinder, the grind adjustment component comprising:

[0005] The adjusting ring is detachably fitted onto the main housing of the coffee grinder and can rotate relative to the main housing about its own axis.

[0006] A positioning structure is provided on the adjusting ring and cooperates with the limiting structure on the main housing. It is used to position the adjusting ring when it is sleeved on the main housing, so that the maximum rotation angle of the adjusting ring relative to the main housing reaches a preset angle.

[0007] In addition, embodiments of this utility model also provide a main housing for a coffee grinder, the main housing comprising:

[0008] The shell body is used to be fitted with the adjusting ring of the grinding adjustment member as described above, so that the adjusting ring is rotatable relative to the shell body about its own axis as the pivot axis;

[0009] A limiting structure is provided on the shell body and cooperates with the positioning structure of the grinding degree adjustment component. It is used to position the adjustment ring when the shell body is sleeved by the adjustment ring, and to limit the rotation angle of the adjustment ring so that the maximum rotation angle of the adjustment ring reaches a preset angle.

[0010] In addition, embodiments of this utility model also provide a coffee grinder, comprising:

[0011] The main unit casing as described above;

[0012] The adjustment rod assembly is disposed within the housing body of the main unit housing;

[0013] The transmission component is disposed within the housing of the main unit and is connected to the adjusting rod assembly;

[0014] A coffee grinding assembly; the coffee grinding assembly includes, along the pivot axis, an outer blade and an inner blade opposite to the outer blade, and the outer blade or the inner blade is connected to the adjusting rod assembly;

[0015] The grinding adjustment component as described above; the adjusting ring of the grinding adjustment component engages with the transmission assembly for transmission, and the adjusting ring is used to drive the adjusting rod assembly to move linearly along the pivot axis through the transmission assembly when rotating, so as to change the grinding gap between the inner blade and the outer blade.

[0016] Compared to existing technologies, the embodiments of this utility model, in order to improve the grinding adjustment mechanism, include an adjusting ring and a positioning structure disposed on the adjusting ring. The adjusting ring can be fitted onto the main housing of the coffee grinder and can rotate relative to the main housing. Simultaneously, the positioning structure positions the adjusting ring when it is fitted onto the main housing, ensuring that the maximum rotation angle of the adjusting ring relative to the main housing reaches a preset angle. Therefore, after the adjusting ring is installed on the main housing, the user or operator can determine whether the installation position of the adjusting ring is correct by rotating it. That is, when the maximum rotation angle of the adjusting ring reaches the preset angle, the installation position of the adjusting ring is considered correct; when the maximum rotation angle of the adjusting ring is less than the preset angle, the installation position is considered incorrect. This method ensures the uniqueness of the installation position of the adjusting ring on the main housing of the coffee grinder, thereby effectively improving the accuracy of the grinding adjustment mechanism in terms of grinding degree.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0027] Example 1

[0028] The first embodiment of this utility model relates to a grind adjustment component for a coffee grinder, such as... Figure 1 , Figure 2 and Figure 3 As shown, the grinding degree adjustment component 1 includes: an adjustment ring 11 and a positioning structure 12. Wherein, combined with... Figure 4 and Figure 5 As shown, the adjusting ring 11 is detachably fitted onto the main housing 2 of the coffee grinder, and the adjusting ring 11 can rotate relative to the main housing 2 with its own axis as the pivot axis.

[0029] In addition, such as Figure 1 and Figure 2As shown, the positioning structure 12 is disposed on the adjusting ring 11 and combined with... Figure 6 As shown, the positioning structure 12 also cooperates with the limiting structure 22 on the main housing 2 to position the adjusting ring 11 when it is sleeved on the main housing 2, so that the maximum rotation angle of the adjusting ring 11 relative to the main housing 2 reaches the preset angle.

[0030] As can be seen from the above, the grind adjustment component 1 includes an adjustment ring 11 and a positioning structure 12 disposed on the adjustment ring 11. The adjustment ring 11 can be fitted onto the main housing 2 of the coffee grinder and can rotate relative to the main housing 2. At the same time, the positioning structure 12 can position the adjustment ring 11 when it is fitted onto the main housing 2, and ensure that the maximum rotation angle of the adjustment ring 11 relative to the main housing 2 reaches a preset angle. Therefore, after the adjustment ring 11 is installed on the main housing 2, the user or operator can determine whether the installation position of the adjustment ring 11 is correct by rotating the adjustment ring 11. That is, when the maximum rotation angle of the adjustment ring 11 reaches the preset angle, the installation position of the adjustment ring 11 can be determined to be correct. When the maximum rotation angle of the adjustment ring 11 is less than the preset angle, the installation position of the adjustment ring 11 can be determined to be incorrect. In this way, the uniqueness of the installation position of the adjustment ring 11 on the main housing 2 of the coffee grinder can be guaranteed, thereby effectively improving the accuracy of the grind adjustment component 1 in adjusting the grind of the coffee grinder assembly 3.

[0031] Specifically, in some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the direction of the adjusting ring 11 around the pivot axis includes: an inner side 111 and an outer side 112 opposite to the inner side 111, while the positioning structure 12 includes: a marker 121 and a positioning block 122. The marker 121 is located on the outer side 112 of the adjusting ring 11 and is combined with... Figure 4 and Figure 5 As shown, the mark 121 is used to align the mark 221 on the main unit housing 2 when the adjusting ring 11 is fitted onto the main unit housing 2. Additionally, as... Figure 2 As shown, the positioning block 122 is disposed on the inner side 111 of the adjusting ring 11, and is combined with Figure 8As shown, the positioning block 122 is used to adjust the ring 11 to rotate from the starting position to the ending position, and to abut against one side of the limiting member 222 of the limiting structure 22. At the same time, the positioning block 122 is also used to adjust the ring 11 to rotate from the ending position to the starting position, and to abut against the other side of the limiting member 222 of the limiting structure 22, and to align the mark 121 with the marker 221. It is easy to see that when the adjusting ring 11 is assembled with the main housing 2, the marking 121 on the adjusting ring 11 can be aligned with the marking 221 on the main housing 2, so that the installation of the adjusting ring 11 is not only directional, but also, after the adjusting ring 11 is installed on the main housing 2, the installation position of the adjusting ring 11 can be judged by rotating the adjusting ring 11. That is, when the adjusting ring 11 is rotated from the end position to the start position, if the positioning block 122 can abut against the other side of the limiting structure 22, and at the same time the marking 121 on the adjusting ring 11 can be aligned with the marking 221 on the main housing 2, the user or operator can determine that the installation position of the adjusting ring 11 is correct.

[0032] Additionally, it's worth noting that when users operate the adjustment ring 11, they cannot see the grinding component 3, making it impossible for them to know the current grind setting. This is especially true when different users are using the grinder, as they cannot know how the previous user adjusted the grind setting. Therefore, when different users use the grinder, they all need to reset the adjustment ring 11 to zero and readjust the grind setting of the grinding component 3 using the adjustment ring 11, which inevitably increases the difficulty of operating the grinder.

[0033] From the above analysis of the positioning structure 12, it is easy to see that when the adjusting ring 11 rotates from the end position to the start position, as Figure 8 As shown, the mark 121 on the adjustment ring 11 is aligned with the mark 221 on the main housing 2. Therefore, each time the user uses the grinder, they can observe the relative position between the mark 121 and the mark 221 to roughly know the grinding degree of the grinding component 3 of the grinder. Therefore, there is no need to zero the adjustment ring 11. The user can quickly adjust the grinding degree of the grinding component 3 by rotating the adjustment ring 11, which effectively reduces the difficulty of operating the grinder and makes the grinder easier for users to use.

[0034] Furthermore, it is worth mentioning that in other embodiments, such as Figure 2As shown, the positioning block 122 is formed by a portion of the inner side 111 of the adjusting ring 11 protruding away from the outer side 112. That is, the positioning block 122 and the adjusting ring 11 are integrally formed, thereby improving the reliability and stability of the adjusting ring 11 during rotation. Of course, in other embodiments, the positioning block 122 can also be an independent component and detachably disposed on the outer side 112 of the adjusting ring 11. However, in this embodiment, the specific arrangement of the positioning block 122 on the adjusting ring 11 is not limited.

[0035] Furthermore, as a preferred embodiment, in other embodiments, such as Figure 1 As shown, several markers 121 can be provided, and each marker 121 is arranged at equal intervals along the circumference of the outer side 112 of the adjusting ring 11. One of the markers 121 is used to align with the markers 221 on the main unit housing 2 when the adjusting ring 11 is fitted onto the main unit housing 2. For example, as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, each label 121 can be an Arabic numeral, and each Arabic numeral can sequentially increase or decrease along the circumference of the outer side 112 of the adjusting ring 11. For example, the Arabic numerals can be set sequentially from 1 to 10. Therefore, when the adjusting ring 11 rotates from the starting position to the ending position, each label 121 on the adjusting ring 11 can sequentially align with the marker 221 on the main housing 2 along its rotation direction. That is, when the adjusting ring 11 rotates to the starting position, the number "1" can be aligned with the marker 221, so that the grinding component 3 has the minimum grinding degree at this time. When the adjusting ring 11 rotates to the ending position, the number "10" can be aligned with the marker 221, so that the grinding component 3 has the maximum grinding degree at this time. It is not difficult to find that in this embodiment, the adjusting ring 11 has multiple adjustment levels for adjusting the grinding degree of the grinding component 3, thereby effectively improving the adjustment accuracy when adjusting the grinding degree of the grinding component 3.

[0036] Additionally, to match the markings 121 on the adjusting ring 11, in other embodiments, such as Figure 1 and Figure 2As shown, the inner side 111 of the adjusting ring 11 is provided with several circumferential grooves 113, and the grooves 113 are arranged at equal intervals along the circumference of the inner side 111. Simultaneously, each groove 113 is used to engage sequentially with a snap-fit ​​member 25 mounted on the main housing 2 along the direction of rotation of the adjusting ring 11. It is easy to see that because the inner side 111 of the adjusting ring 11 is provided with multiple circumferential grooves 113, when the adjusting ring 11 rotates relative to the main housing 2, the sequential engagement of each groove 113 with the snap-fit ​​member 25 on the main housing 2 provides a certain tactile feedback during rotation. This improves both the feel of the adjusting ring 11 during rotation and the accuracy of adjusting the grinding degree of the grinding component 3.

[0037] Additionally, it is worth mentioning that in some other embodiments, such as Figure 1 and Figure 2 As shown, the inner side 111 of the adjusting ring 11 is provided with an inner toothed ring 13 composed of several teeth 131 along its circumference. The inner toothed ring 13 is used to drive the adjusting rod assembly 4 of the grinder to move linearly along the pivot axis when the adjusting ring 11 rotates relative to the main housing 2, so that the adjusting rod assembly 4 can adjust the grinding gap between the inner blade 31 and the outer blade 32 of the grinding assembly 3.

[0038] Example 2

[0039] Embodiment 2 of this utility model relates to the main body housing of a coffee grinder, such as... Figure 6 As shown, the main unit housing 2 includes: a housing body 21 and a limiting structure 22. Among them, combined with... Figure 4 and Figure 5 As shown, the shell body 21 is used to be fitted with the adjusting ring 11 of the grinding degree adjusting member 1 as described in Embodiment 1, so that the adjusting ring 11 can rotate relative to the shell body 21 about its own axis as the pivot axis.

[0040] In addition, such as Figure 6 As shown, the limiting structure 22 is disposed on the shell body 21, and the limiting structure 22 cooperates with the positioning structure 12 of the grinding degree adjustment component 1. The limiting structure 22 is used to position the adjusting ring 11 when the shell body 21 is sleeved with the adjusting ring 11, and to limit the rotation angle of the adjusting ring 11 so that the maximum rotation angle of the adjusting ring 11 reaches the preset angle.

[0041] As can be seen from the above, the main housing 2 includes a housing body 21 and a limiting structure 22 disposed on the housing body 21. The housing body 21 can be sleeved by the adjusting ring 11 of the grinding degree adjusting component 1, and the adjusting ring 11 can rotate relative to the housing body 21 with its own axis as the pivot axis. At the same time, the limiting structure 22 can position the adjusting ring 11 when the housing body 21 is sleeved by the adjusting ring 11, and can limit the rotation angle of the adjusting ring 11, so that the maximum rotation angle of the adjusting ring 11 reaches the preset angle. Therefore, after the adjustment ring 11 is installed on the main housing 2, the user or operator can determine whether the installation position of the adjustment ring 11 is correct by rotating the adjustment ring 11. That is, when the maximum rotation angle of the adjustment ring 11 reaches the preset angle, it can be determined that the installation position of the adjustment ring 11 is correct. When the maximum rotation angle of the adjustment ring 11 is less than the preset angle, it can be determined that the installation position of the adjustment ring 11 is incorrect. In this way, the uniqueness of the installation position of the adjustment ring 11 on the main housing 2 can be guaranteed, thereby effectively improving the accuracy of the grinding adjustment component 1 when adjusting the grinding degree of the grinding component 3.

[0042] Specifically, in some embodiments, such as Figure 6 and Figure 7 As shown, the shell body 21, about the pivot axis, includes: an inner shell 211 and an outer shell 212 opposite to the inner shell 211. The outer shell 211 is fitted with the adjusting ring 11, and a channel 213 is formed between the outer shell 212 and the inner shell 211 to feed coffee beans into the grinding assembly 3. Additionally, as... Figure 6 and Figure 7 As shown, the limiting structure 22 includes: a marker 221 and a limiting member 222, wherein the marker 221 is disposed on the outer surface of the housing 212 and combined with... Figure 4 As shown, the marker 221 is used to align the marking 121 on the adjusting ring 11 when the housing 212 is fitted with the adjusting ring 11. Secondly, as... Figure 6 and Figure 7As shown, the limiting member 222 is disposed on the outer surface of the housing 212. The limiting member 222 is used to abut against one side of the positioning block 122 of the positioning structure 12 when the adjusting ring 11 rotates from the starting position to the ending position. At the same time, the limiting member 222 is also used to abut against the other side of the positioning block 122 of the positioning structure 12 when the adjusting ring 11 rotates from the ending position to the starting position, and to align the marker 221 with the mark 121. It is easy to see that when the adjusting ring 11 is assembled with the outer shell 212 of the shell body 21, the marking 221 on the outer surface of the outer shell 212 can be used to align the marking 121 on the adjusting ring 11. This makes the installation of the adjusting ring 11 not only directional, but also, after the adjusting ring 11 is installed on the outer shell 212 of the shell body 21, the installation position of the adjusting ring 11 can be judged by rotating the adjusting ring 11. That is, when the adjusting ring 11 is rotated from the end position to the start position, if the limiting member 222 can abut against the other side of the positioning structure 12, and at the same time the marking 221 on the outer shell 212 is aligned with the marking 121 on the adjusting ring 11, the user or operator can determine that the installation position of the adjusting ring 11 is correct.

[0043] Furthermore, it should be noted that the limiting member 222 can be a limiting block entirely disposed on the outer surface of the housing 212, such that both sides of the limiting member 222 in the direction of the pivot axis can serve as the abutting sides where the adjusting ring 11 abuts against the positioning block 122 during rotation. Of course, as an alternative, in other embodiments, such as... Figure 6 and Figure 7 As shown, the limiting member 222 includes a first limiting protrusion 2221 and a second limiting protrusion 2222. Both the first limiting protrusion 2221 and the second limiting protrusion 2222 are formed by a portion of the outer surface of the outer shell 212 protruding away from the inner shell 211. Therefore, the first limiting protrusion 2221 can abut against one side of the positioning block 122 when the adjusting ring 11 rotates from the end position to the start position. The second limiting protrusion 2222 can abut against the other side of the positioning block 122 when the adjusting ring 11 rotates from the start position to the end position.

[0044] Meanwhile, since the limiting member 222 is composed of a first limiting protrusion 2221 and a second limiting protrusion 2222, a notch 2223 can be formed between the first limiting protrusion 2221 and the second limiting protrusion 2222. And corresponding to the notch 2223, such as... Figure 6 and Figure 7 As shown, the main housing 2 also includes: a connecting sleeve 24, a snap-fit ​​member 25, and an elastic member 26. The connecting sleeve 24 is disposed between the inner housing 211 and the outer housing 212, allowing the connecting sleeve 24 to connect to both the inner housing 211 and the outer housing 212 respectively, and the connecting sleeve 24 is also radially opposite to the notch 2223 of the outer housing 212. Secondly, as... Figure 6 and Figure 7 As shown, the snap-fit ​​member 25 is disposed within the connecting sleeve 24, and the snap-fit ​​member 25 is radially slidable along the outer shell 212. The snap-fit ​​member 25 includes: a limiting seat 251 slidably disposed within the connecting sleeve 24; and a stop bar 252 disposed on the side of the limiting seat 251 relative to the outer shell 212, with a portion of the stop bar 252 passing through the outer shell 212 and entering the notch 2223. Finally, an elastic member 26 is disposed on the side of the limiting seat 251 relative to the inner shell 211. This elastic member 26 applies a restoring force to the limiting seat 251, allowing the stop bar 252 to abut against the inner side 111 of the adjusting ring 11. Therefore, in practical applications, combined with... Figure 8 As shown, when the adjusting ring 11 rotates relative to the housing body 21, the stop lever 252 can sequentially engage with each of the stop slots 113 of the adjusting ring 11 along the rotation direction of the adjusting ring 11. It is easy to see that, under the rebound action of the elastic element 26, the limiting seat 251 can drive the stop lever 252 to always abut against the inner side 111 of the adjusting ring 11. Therefore, when the adjusting ring 11 rotates relative to the outer shell 212 of the housing body 21, the stop lever 252 can sequentially engage with each of the stop slots 113 around the rotation direction of the adjusting ring 11, giving the adjusting ring 11 a certain tactile feedback during rotation. This improves the feel of the adjusting ring 11 while further enhancing the accuracy of the adjusting ring 11 in adjusting the grinding degree of the grinding assembly 3.

[0045] Furthermore, due to the gap 2223 formed between the first limiting protrusion 2221 and the second limiting protrusion 2222, if the installation position of the adjusting ring 11 on the shell body 21 deviates, the positioning block 122 on the adjusting ring 11 will enter the gap 2223. Thus, when the adjusting ring 11 rotates, it will be limited by the positioning block 122 in the gap 2223, causing the maximum rotation angle of the adjusting ring 11 to be much smaller than the preset angle. At this time, the user or operator can determine that the installation position of the adjusting ring 11 on the shell body 21 is incorrect, and therefore it is necessary to reinstall or adjust the installation position of the adjusting ring 11 on the shell body 21.

[0046] Example 3

[0047] Embodiment 3 of this utility model relates to a coffee grinder, such as... Figure 4 , Figure 5 and Figure 9 As shown, the coffee grinder includes: a main housing 2 as described in Embodiment 2, an adjusting rod assembly 4, a transmission assembly 5, a grinding assembly 3, and a grinding degree adjusting component 1 as described in Embodiment 1.

[0048] Among them, such as Figure 4 , Figure 5 and Figure 9As shown, both the adjusting rod assembly 4 and the transmission assembly 5 are housed within the shell body 21 of the main housing 2, and the transmission assembly 5 is connected to the top of the adjusting rod assembly 4. Next, as... Figure 9 As shown, the grinding assembly 3 includes, along the pivot axis, an outer blade 32 and an inner blade 31 opposite to the outer blade 32, and either the outer blade 32 or the inner blade 31 can be connected to the bottom of the adjusting rod assembly 4. Finally, the adjusting ring 11 of the grind adjustment component 1 engages with the transmission assembly 5 for transmission, and the adjusting ring 11 is used to drive the adjusting rod assembly 4 to move linearly along the pivot axis via the transmission assembly 5 during rotation, thereby changing the grinding gap between the inner blade 31 and the outer blade 32.

[0049] Furthermore, in order to enable the adjusting ring 11 to drive the adjusting rod assembly 4 to move linearly along the pivot axis via the transmission assembly 5, in some embodiments, such as Figure 9 As shown, the transmission assembly 5 includes: a lead screw sleeve 51 sleeved on the top of the adjusting rod assembly 4, an outer gear ring 52 sleeved on the lead screw sleeve 51, and a gear 53 disposed between the inner gear ring 13 and the outer gear ring 52. Wherein, as... Figure 9 As shown, the lead screw sleeve 51 is coaxially fixed with the adjusting rod assembly 4, and the outer surface of the outer gear ring 52 is the outer tooth surface that meshes with the inner gear ring 13, while the inner surface of the outer gear ring 52 is the inner thread surface that is threadedly connected to the lead screw sleeve 51. Thus, when the adjusting ring 11 rotates, it can drive the outer gear ring 53 to rotate through meshing with the gear 53. At the same time, when the outer gear ring 52 rotates, it can also be threadedly connected to the lead screw sleeve 51, so that the lead screw sleeve 41 can change the rotational motion of the outer gear ring 52 into a linear motion of the lead screw sleeve 41 along the pivot axis. Thus, when the bottom of the adjusting rod assembly 4 is connected to the inner cutter disc 31, the adjusting rod assembly 4 can drive the inner cutter disc 31 to move relative to the outer cutter disc 32 through its own linear motion, thereby achieving the purpose of adjusting the grinding gap between the inner cutter disc 31 and the outer cutter disc 32.

[0050] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
