[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: Figure 1-11As shown, the device with grinding function includes a machine body 1 and an upper cutter disc 2 and a lower cutter disc 3 arranged at intervals in the upper and lower parts of the machine body 1. The machine body 1 is rotatably connected to a cutter disc adjustment seat 4 on one side of the upper cutter disc 2. When the cutter disc adjustment seat 4 rotates relative to the machine body 1, the upper cutter disc 2 moves closer to or away from the lower cutter disc 3. The cutter disc adjustment seat 4 includes a seat body 401 rotatably connected to the machine body 1. An exposed opening 402 is provided on the side of the seat body 401 opposite to the upper cutter disc 2. A ball 403 is provided in the seat body 401, which partially extends out of the exposed opening 402 and abuts against the upper cutter disc 2. When the seat body 401 rotates relative to the machine body 1, the ball 403 rolls along the upper cutter disc 2 relative to the seat body 401 and the upper cutter disc 2. The present embodiment provides a device with a grinding function to solve the problem that when the adjustment seat of the existing coffee machine rotates relative to the machine body, it contacts with the upper cutter disc surface, has large friction, is difficult to twist, and is prone to generate metal chips. The cutter disc adjustment seat 4 is mainly configured as a seat body 401 that is rotatably connected to the machine body 1 and has an exposed opening 402, and a ball 403 is configured in the seat body 401 so that a portion of the seat body 401 extends from the exposed opening 402 and abuts against the upper cutter disc 2. When the seat body 401 rotates relative to the machine body 1, the ball 403 rolls along the upper cutter disc 2 relative to the seat body 401 and the upper cutter disc 2. That is, when the seat body 401 rotates relative to the machine body 1, there is rolling friction (point contact) between the seat body 401 and the upper cutter disc 2, which has small friction, smooth rotation, and is not prone to generate metal chips, thereby providing a good user experience.

[0030] In the embodiment of the utility model, there are multiple exposed openings 402 and balls 403, which are arranged at intervals in the circumferential direction of the seat body 401. Since there are multiple exposed openings 402 and balls 403, the seat body 401 rotates more smoothly and the structure is more stable.

[0031] In the embodiment of the utility model, the portion of the ball 403 extending from the exposed opening 402 to the seat body 401 accounts for 1 / 10 to 1 / 8 of the ball 403. Since the portion of the ball 403 extending from the seat body 401 accounts for 1 / 10 to 1 / 8 of the ball 403, even if the seat body 401 rotates relative to the machine body 1, there is rolling friction between the seat body 401 and the upper blade 2, and the ball 403 is prevented from being easily dropped due to excessive exposure, and the assembly stability is high.

[0032] In the embodiment of the utility model, the seat body 401 has an assembly hole 404 extending from the external opening 402 in a direction away from the upper blade disc 2, and a stopper 405 at least partially extending into the assembly hole 404 to limit the ball 403 from moving away from the assembly hole 404 is detachably fixedly connected to the seat body 401. Since the seat body 401 has an assembly hole 404 extending upward from the external opening 402, and the stopper 405 at least partially extending into the assembly hole 404 to limit the ball 403 from moving away from the assembly hole 404 is detachably fixedly connected to the seat body 401, the ball 403 has good assembly stability and is easy to disassemble, assemble and replace.

[0033] In the embodiment of the present utility model, the aperture of the exposed port 402 is smaller than the diameter of the ball 403, and the aperture of the assembly hole 404 is not smaller than the diameter of the ball 403.

[0034] In the embodiment of the present utility model, the ball 403 can move along the assembly hole 404 to abut against or disengage from the limiting member 405. When the ball 403 disengages from the limiting member 405, the distance between the ball 403 and the limiting member 405 is defined as h1. When the ball 403 disengages from the limiting member 405, the distance between the lowermost end of the part of the ball 403 extending out of the seat body 401 and the exposed port 402 is defined as h2, and h1 < h2. Since h1 < h2, when the ball 403 abuts against the limiting member 405, part of the ball 403 extends out of the seat body 401. When the ball 403 disengages from the limiting member 405, it abuts against the seat body 401 and part of it extends out of the seat body 401. That is, when the ball 403 moves along the assembly hole 404 to abut against or disengage from the limiting member 405, the ball 403 always keeps part of it extending out of the seat body 401. That is, when the seat body 401 rotates relative to the machine body 1, the ball 403 always abuts against the upper tool holder 2 and is slidably connected to the upper tool holder 2, so as to ensure that the seat body 401 and the upper tool holder 2 are in rolling friction. And the ball 403 can move along the assembly hole 404 to make the ball 403 have a certain activity space, and the rolling is smoother and more fluent.

[0035] In the embodiment of the present utility model, the limiting member 405 has an axially extending portion 406 and a radially protruding flange 407. A counterbore 408 for the radially protruding flange 407 to be embedded is provided on the side of the seat body 401 facing away from the upper tool holder 2, and the axially extending portion 406 is connected to the radially protruding flange 407 and extends into the assembly hole 404. Since the seat body 401 is provided with the counterbore 408 and the limiting member 405 has the radially protruding flange 407 embedded in the counterbore 408 and the axially extending portion 406 extending into the assembly hole 404, the limiting member 405 has good assembly stability.

[0036] In the embodiment of the present utility model, fasteners 409 for locking the limiting member 405 to the seat body 401 are provided on the radially protruding flange 407. There are 2 fasteners 409, and the two fasteners 409 are respectively arranged on opposite sides of the axially extending portion 406. Specifically, the fastener 409 is a bolt. Since the fasteners 409 for locking the limiting member 405 to the seat body 401 are provided on the radially protruding flange 407, the limiting member 405 can be detachably and fixedly connected to the seat body 401. And since there are 2 fasteners 409 and they are respectively arranged on opposite sides of the axially extending portion 406, the connection between the limiting member 405 and the seat body 401 is firm.

[0037] In the embodiment of the utility model, the stopper 405 is made of an elastic material or a metal material. Specifically, the stopper 405 can be made of, but not limited to, plastic or nylon. Since the stopper 405 is made of an elastic material, it can play a certain buffering role when the ball 403 hits the stopper 405 to avoid damage.

[0038] In the embodiment of the utility model, the outer ring of the seat body 401 is provided with a connecting ring 410 threadedly connected to the body 1 .
