[0040] The outer grinding assembly is detachably arranged in the grinding chamber 11, and the outer grinding assembly includes an outer grinding blade 3 sleeved on the outer side of the inner grinding blade 4 and a mounting seat 2 detachably connected to the grinding chamber 11, and the outer grinding blade 3 is arranged on the mounting seat 2. Specifically, the mounting seat 2 is sleeved on the outer side of the outer grinding blade 3, and when the outer grinding assembly is taken out of the grinding chamber 11, the outer grinding assembly can be lifted upward from the notch of the grinding chamber 11, so as to take out the outer grinding assembly.

[0041] In some specific embodiments, a first connecting portion is provided on the inner wall of the grinding chamber 11, and a second connecting portion is provided on the outer wall of the mounting seat 2, and the first connecting portion and the second connecting portion are detachably connected.

[0042] In some specific embodiments, a plurality of first connection parts are provided on the circumference of the inner wall of the grinding chamber 11, and a plurality of second connection parts are provided on the circumference of the outer wall of the mounting seat 2, and the plurality of first connection parts are connected to the plurality of second connection parts in a one-to-one correspondence.

[0043] In some specific embodiments, Figures 2 to 4As shown, each of the first connection parts is a block 111, and each of the second connection parts is an arc groove 21 extending circumferentially around the outer wall of the mounting seat 2. The opening of the arc groove 21 is provided with a notch 212 for the corresponding block 111 to axially disengage from the arc groove 21; specifically, each of the arc grooves 21 is provided with an upper side wall 213 on the upper side, and a lower side wall 214 on the lower side, and a bottom wall is provided between the upper side wall 213 and the lower side wall 214. The preferred solution is that the upper side walls 213 of all the arc grooves 21 are connected to each other. The number of the arc grooves 21 is preferably three, and they are equidistantly arranged circumferentially around the outer wall of the mounting seat 2, and accordingly, the number of the blocks 111 is three.

[0044] When the mounting seat 2 is installed in the grinding chamber 11, the mounting seat 2 is rotated forward so that the clamping block 111 slides along the corresponding arc groove 21 until it abuts against the bottom wall of the arc groove 21. When the clamping block 111 abuts against the bottom wall of the arc groove 21, it cannot be rotated further, i.e., it is clamped in the arc groove 21. When the mounting seat 2 is removed, the mounting seat 2 is rotated backward so that the clamping block 111 slides to the clearance notch 212 of the arc groove 21 and the mounting seat 2 is lifted up to be detached from the grinding chamber 11.

When rotating in the opposite direction, the resistance of the arc-shaped protrusion 211 needs to be overcome to make the block 111 disengage from the arc groove 21. Therefore, when the arc-shaped protrusion 112 is stuck between the arc-shaped protrusion 211 and the bottom wall of the arc groove 21, the connection between the mounting seat 2 and the grinding chamber 11 is more stable.

[0047] In some specific embodiments, in order to prevent coffee powder from entering the body of the coffee bean grinder from the gap between the grinding chamber 11 and the mounting seat 2, a sealing ring 6 is provided between the inner wall of the grinding chamber 11 and the outer wall of the mounting seat 2. The sealing ring 6 can be arranged at the lower side of the arc groove 21, specifically, a sealing ring groove is provided on the outer wall of the mounting seat 2, and the sealing ring 6 is arranged in the sealing ring groove.

[0048] In some specific embodiments, in order to facilitate the user to disassemble and assemble the mounting seat 2, a handle 5 is provided on the mounting seat 2. The handle 5 can be set in an arc or semicircular shape, and both ends of the handle 5 are rotatably connected to the mounting seat 2. Specifically, both opposite sides of the upper end of the mounting seat 2 are provided with plug-in slots, and the two ends of the handle 5 are rotatably set in the two plug-in slots, and after the mounting seat 2 is installed, the handle 5 can be rotated to abut against the annular step 22, so as to facilitate the coffee beans to enter the gap between the outer grinder 3 and the inner grinder 4.

[0049] In some specific embodiments, Figure 2 and Figure 5 As shown, in order to further facilitate the user to clean the external grinding knife 3, the external grinding knife 3 is detachably connected to the mounting seat 2. The specific structure can be set as follows: an annular step 22 is provided around the upper part of the inner side wall of the mounting seat 2, and an elastic hook 23 is provided around the lower part of the inner side wall of the mounting seat 2, and the external grinding knife 3 is limited between the annular step 22 and the elastic hook 23. The elastic hook 23 is preferably two, respectively located on opposite sides of the external grinding knife 3. When disassembling or installing, the external grinding knife 3 is disassembled and installed from the bottom of the mounting seat 2.

[0050] Embodiment 2:

[0051] This embodiment provides a coffee bean grinder, comprising a bean grinding device with a detachable outer grinding component as described in any scheme in the first embodiment.

[0052] Working principle description:

[0053] When the user installs the mounting seat 2 in the grinding chamber 11, the user first aligns the block 111 with the clearance notch 212 of the arc groove 21, and then rotates the mounting seat 2 forward to make the block 111 slide along the corresponding arc groove 21. When the block 111 slides to a position against the bottom wall of the arc groove 21, the mounting seat 2 cannot be rotated further, that is, it is installed in place.

[0054] When removing the mounting seat 2 , firstly rotate the mounting seat 2 in the opposite direction to make the clamping block 111 slide to the clearance notch 212 of the arc groove 21 , and then lift the mounting seat 2 upward to make the mounting seat 2 and the outer grinding blade 3 separate from the grinding chamber 11 .
