[0047] Example

[0048] See Figures 1-3 In this embodiment, a coffee grinder is proposed, including a grinder 100 and a main body 200, wherein the main body 200 is provided with a connecting structure 300. Figure 3 The local area was subjected to cross-sectional processing.

[0049] The grinding device 100 is movably connected to the main body 200 via a connecting structure 300. The connecting structure 300 includes a first connecting end 301 and a second connecting end 302. The first connecting end 301 is movably connected to the grinding device 100, and the second connecting end 302 is movably connected to the main body 200.

[0050] The grinding device 100 has a first position and a second position relative to the main body 200:

[0051] like Figure 1 As shown, when the grinding device 100 is in the first position, the overall height of the coffee grinder is the first height;

[0052] like Figure 2 and Figure 3 As shown, when the grinding device 100 is in the second position, the overall height of the coffee grinder is the second height, and the powder discharge port 111 of the grinding device 100 faces the preset direction for discharging coffee powder.

[0053] The first elevation is lower than the second elevation. (Refer to...) Figure 1 and Figure 3 When the coffee grinder is placed on a horizontal surface, the vertical direction is the height direction of the coffee grinder. The maximum distance between the top and bottom of the coffee grinder is the overall height of the coffee grinder.

[0054] In this embodiment, the user can adjust the grinding device 100 to a first position and a second position relative to the main body 200, thereby adjusting the overall height of the coffee grinder. When the grinding device 100 is in the first position relative to the main body 200, the overall height of the coffee grinder can be reduced, making it easier to store; when the grinding device 100 is in the second position relative to the main body 200, it is easier to discharge the coffee powder ground by the grinding device 100.

[0055] like Figure 3 As shown, the connection structure 300 includes a first connector 310 and a second connector 320, which are rotatably connected.

[0056] The first connecting end 301 is located on the first connecting member 310 and is rotatably connected to the grinding device 100; the second connecting end 302 is located on the second connecting member 320 and is rotatably connected to the main body 200. The rotatable connection can be achieved through a rotating shaft or similar means.

[0057] When the user drives the grinding device 100 to move relative to the main body 200, the grinding device 100 rotates relative to the first connector 310, the first connector 310 rotates relative to the second connector 320, and the second connector 320 rotates relative to the main body 200.

[0058] like Figures 1-3 As shown, the coffee grinding device 100 includes a housing 110, on which a coffee inlet 112 is provided. Inside the housing 110, a coffee feeding channel 120 and a coffee grinding mechanism 130 are provided. The coffee inlet 112 is connected to the coffee feeding channel 120. The powder discharge port 111 is located at the end of the housing 110.

[0059] The feed side of the grinding mechanism 130 faces the bean feeding channel 120, and the discharge side of the grinding mechanism 130 faces the powder discharge port 111. When the grinding device 100 is in the second position, the feed side of the grinding mechanism 130 is located above the discharge side.

[0060] The bean feeding channel 120 is used to feed coffee beans entering from the bean inlet 112 to the grinding mechanism 130; the grinding mechanism 130 is used to grind the coffee beans fed into the bean feeding channel 120 to obtain coffee powder.

[0061] The process of grinding coffee beans using a 100-grinding device is roughly as follows:

[0062] A certain amount of coffee beans are fed into the grinding device 100 through the bean inlet 112. At this time, the grinding device 100 can be in the first position or the second position.

[0063] Adjust the grinding device 100 to the second position, or keep the grinding device 100 in the second position. At this time, under the action of gravity, the coffee beans in the grinding device 100 move through the bean feeding channel 120 to the feeding side of the grinding mechanism 130 and gradually enter the grinding mechanism 130.

[0064] Under the action of the grinding mechanism 130, coffee beans are ground into coffee powder. The coffee powder moves to the discharge port 111 through the discharge side of the grinding mechanism 130 and is discharged out of the grinding device 100 through the discharge port 111.

[0065] During the grinding of coffee beans, the coffee caddy needs to be placed in the position corresponding to the coffee discharge port 111 to receive the coffee powder discharged from the grinder 100. After grinding the coffee beans, turn off the grinder 100 and put the coffee caddy containing the coffee powder into the designated position on the coffee machine, and then you can start brewing coffee.

[0066] like Figure 4 As shown, the coffee grinding mechanism 130 includes a moving grinding element 131, a fixed grinding element 132, and a drive module 133. A grinding gap 140 for grinding coffee beans is formed between the moving grinding element 131 and the fixed grinding element 132. The drive module 133 is used to drive the moving grinding element 131 to rotate, so that the moving grinding element 131 and the fixed grinding element 132 rotate relative to each other.

[0067] The drive module 133 includes a motor, and the output shaft of the motor is fixedly connected to the moving grinding element 131. When the motor starts, the moving grinding element 131 rotates synchronously with the output shaft of the motor.

[0068] like Figure 5 As shown, the fixed grinding element 132 includes a bean inlet hole 1321 and a grinding hole 1322, which are interconnected. The movable grinding element 131 passes through the bean inlet hole 1321 and partially extends into the grinding hole 1322. The bean inlet hole 1321 and the grinding hole 1322 can be coaxially arranged.

[0069] like Figure 6 As shown, both the bean inlet hole 1321 and the grinding hole 1322 are tapered holes. The upper part of the fixed grinding component 132 is the feeding side, and the lower part is the discharge side. From the feeding side to the discharge side, the cross-sectional area of ​​the bean inlet hole 1321 gradually decreases, while the cross-sectional area of ​​the grinding hole 1322 gradually increases.

[0070] A bean inlet gap 150 is formed between the inner wall of the bean inlet hole 1321 and the moving grinding part 131.

[0071] The moving grinding element 131 includes a grinding head 1311, which is at least partially located within a grinding hole 1322. A grinding gap 140 is located between the inner wall of the grinding hole 1322 and the grinding head 1311. The grinding hole 1322 and the grinding head 1311 may be coaxially arranged.

[0072] In this embodiment, the grinding hole 1322 is a tapered hole, and the outer surface of the grinding head 1311 is a tapered surface. The tapers of the tapered portion and the tapered surface correspond to each other. In some embodiments, the tapers of the tapered portion and the tapered surface may be the same or similar.

[0073] The coffee grinding device 100 includes an adjustment module. This module drives the stationary grinding element 132 to move along its own axial direction to adjust the size of the grinding gap 140. Since the grinding hole 1322 is a tapered hole and the outer surface of the grinding head 1311 is a tapered surface, the size of the grinding gap 140 changes as the stationary grinding element 132 moves along its own axial direction. Adjusting the size of the grinding gap 140 allows for adjustment of the coarseness of the ground coffee powder.

[0074] like Figure 4 and Figure 6 As shown, the adjustment module includes an adjustment component 410, a connecting ring 420, and a mounting ring 430.

[0075] In this embodiment, the adjusting member 410 is arc-shaped and rotatably connected to the outer casing 110. In other embodiments, the adjusting member 410 may be annular.

[0076] A handle 411 is fixedly mounted on the outer wall of the adjusting component 410, and an opening 113 is provided on the outer casing 110. The handle 411 passes through the opening 113 and partially extends out of the outer casing 110. The user can drive the adjusting component 410 to rotate by driving the handle 411.

[0077] In this embodiment, the inner wall of the adjusting member 410 is provided with internal teeth, and the outer wall of the connecting ring 420 is provided with external teeth. The internal teeth are used to mesh with the external teeth. When the adjusting member 410 rotates, the connecting ring 420 will rotate accordingly due to the interaction between the internal and external teeth.

[0078] The connecting ring 420 is sleeved on the outside of the mounting ring 430, and the connecting ring 420 is threadedly connected to the mounting ring 430. When the connecting ring 420 rotates, the mounting ring 430 will move along its own axial direction under the action of the thread.

[0079] The mounting ring 430 is fixedly connected to the fixed grinding part 132, and the two are coaxially arranged. When the mounting ring 430 moves along its own axial direction, the fixed grinding part 132 also moves accordingly. Specifically, the fixed grinding part moves along its own axial direction.

[0080] like Figure 6 As shown, the inner wall of the bean inlet 1321 is provided with bean-holding grooves 161, and there are multiple bean-holding grooves 161 arranged in a circular array. The bean-holding grooves 161 can hold one or more coffee beans and can accurately guide the coffee beans into the grinding hole 1322. During the grinding process, the coffee beans in the bean inlet 1321 are initially ground by the action of the moving grinding element 131.

[0081] like Figure 6 As shown, the inner wall of the grinding hole 1322 is provided with grinding teeth 162, and there are multiple grinding teeth 162 distributed in a ring array. During the grinding process, under the action of the grinding teeth 162 and the grinding head 1311, the coffee beans are finely ground to obtain coffee powder of the required coarseness.

[0082] like Figure 2 As shown, the main body 200 has a receiving space 210 on its top, which is used to receive the bean grinder 100.

[0083] In this embodiment, compared to the second position, when the grinding device 100 is in the first position, a larger portion of the grinding device 100 is located within the receiving space 210. Furthermore, when the grinding device 100 is in the first position, it is supported by the bottom of the receiving space 210 and is in a stable state; at this time, the overall height of the coffee grinder is at its minimum.

[0084] like Figure 1 and Figure 2 As shown, the coffee grinder 100 is equipped with a handle 114. The user can adjust the relative position between the coffee grinder 100 and the main body 200 by holding and driving the handle 114. The handle 114 is located on the outer casing 110.

[0085] like Figure 7 As shown, the grinding device 100 is detachably connected to the main body 200. Specifically, after moving the grinding device 100 to the second position, the grinding device 100 can be separated from the main body 200 by pulling out the pivot connecting the grinding device 100 to the connecting structure 300.

[0086] The grinding device 100 is electrically connected to the main body 200 via a wire 500, wherein the wire 500 is detachably connected to the grinding device 100 and / or the main body 200 via a connector 510.

[0087] Connector 510 includes quick couplings. There are many types of quick couplings; please refer to existing designs for details.

[0088] In this embodiment, the connector 510 includes a USB plug and a USB interface. One end of the wire 500 is provided with a USB plug, and the other end is fixed and electrically connected to the main body 200; the grinding device 100 is provided with a USB interface.

[0089] In some other embodiments, both ends of the wire 500 are detachably electrically connected to the grinding device 100 and the main body 200 respectively via corresponding connectors 510.

[0090] In this application, the position of the grinding device 100 on the coffee grinder is adjustable, thereby enabling the overall height of the coffee grinder to be adjusted to suit the corresponding scenarios: when the coffee grinder needs to be stored, the grinding device 100 can be adjusted to the first position; when the coffee beans need to be ground, the grinding device 100 can be adjusted to the second position.

[0091] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
