The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The knob assembly, which is easily removable and is shown in fig. 1-7, is used in conjunction with an adjustment ring 600, where the adjustment ring 600 is mounted to the grinder 500.

The knob subassembly include: knob 100, knob lower cover 200 and knob cover 300.

A central column and a central hole are correspondingly arranged between the knob 100 and the knob lower cover 200, and are connected through a rotating shaft, so that the knob 100 and the knob lower cover 200 can rotate relatively; specifically, a center post is arranged on the lower knob cover 200, a center hole is arranged on the knob 100, and the center post is inserted into the center hole and assembled through a rotating shaft during installation; if the knob 100 is set to be stationary, the knob lower cover 200 may be rotated about the rotation axis;

a torsion spring 400 is arranged between the knob 100 and the knob lower cover 200, and the torsion spring 400 provides a force for relative rotation between the knob 100 and the knob lower cover; the torsion spring 400 can be sleeved on the central column, and one end of the torsion spring is limited at the knob 100, and the other end of the torsion spring is limited at the knob lower cover 200, when the rotation is generated, due to the elastic force of the torsion spring 400, when the external force disappears, the knob 100 and the knob lower cover 200 can be rotated and reset.

Furthermore, a limit structure is arranged between the knob 100 and the knob lower cover 200, the limit structure limits the rotation angle between the knob 100 and the knob lower cover 200, the knob 100 is provided with a limit groove 101, the knob lower cover 200 is provided with a dial knob 201, the dial knob 201 penetrates through the limit groove 101 to extend upwards, and the rotation angle between the knob 100 and the knob lower cover 200 is limited through the dial knob 201 and the limit groove 101;

generally, the rotation angle between the knob 100 and the knob lower cover 200 is about 10 °.

As shown in fig. 4, the knob assembly is in an unlocked state, and under the premise that the position of the knob 100 is not changed, the torsion spring 400 provides a counterclockwise force to the knob lower cover 200, so that the knob lower cover 200 maintains a counterclockwise force, and the knob assembly can be maintained in a locked state all the time;

when unlocking, a force which is approximately leftward should be used for dialing the toggle button 201 to rotate clockwise, the toggle button is rotated to the left side of the limiting groove 101 and is in an unlocking state, after the external force disappears, under the acting force of the torsion spring 400, the lower knob cover 200 rotates anticlockwise, the toggle button 201 rotates anticlockwise and moves to the right side of the limiting groove 101, and the locking state is recovered.

Furthermore, the lower knob cover 200 is provided with a limiting hole 202 and a hook 203, and the hook 203 is used for being matched and locked with the adjusting ring 600 in the following.

The bottom of the knob 100 protrudes downwards to form a hollow plug bush 110, and the side surface of the plug bush 110 is provided with a notch 111; during assembly, the plug bush 110 is inserted into the limit hole 202; the insert 110 is configured to mate with the adjustment ring 600 later during assembly.

As shown in fig. 5, before the knob assembly is assembled with the adjustment ring 600, the pins 610 of the adjustment ring 600 correspond to the sockets 110 of the knob assembly, and the lower knob cover 200 is rotated to the unlocked state; then, the pin 610 is vertically inserted downwards into the plug bush 110, and meanwhile, the clamping groove 620 on the pin 610 corresponds to the notch 111 of the plug bush 110, and finally, after the external force disappears, under the action force of the torsion spring 400, the hook 203 moves rightwards along with the rotation of the knob lower cover 200 and is matched and clamped with the clamping groove 620, and the knob assembly and the adjusting ring 600 are locked and installed after being clamped;

in practical use, the lower knob cover 200 does not need to be shifted to an unlocking state, guide surfaces are arranged on the pin 610 and the hook 203, the pin 610 pushes the hook 203 open (i.e. pushes the lower knob cover 200 to rotate) in the process of inserting the pin 610 into the plug bush 110, after the pin is pushed open and corresponds to the slot 620, the lower knob cover 200 is reset under the action of the torsion spring 400, and the hook 203 and the slot 620 are locked to complete assembly;

when the knob assembly needs to be disassembled, the user only needs to apply force to roughly shift the dial button 201 leftwards as shown in fig. 4, so that the whole knob lower cover 200 rotates, the hook 203 is separated from the clamping groove 620 after the rotation, and the knob assembly can be pulled upwards to be separated from the adjusting ring 600.

During unlocking, when the dial button 201 moves to the unlocking state, the external force disappears, and the dial button automatically resets and rotates to the locking state under the action of the torsion spring 400; optionally, in other embodiments, a limiting structure may be further added, so that the dial 201 may be maintained in an unlocked state, and then the knob assembly may be removed upward, when locking is needed, a force may be applied to optionally dial the dial 201, and after the dial is disengaged from the limiting structure, the dial automatically returns to the locked state under the action of the torsion spring 400.

Specifically, the cross-section of knob 100 and knob lower cover 200 all be circular, can guarantee between the two can relative rotation, and the setting of knob lid 300 for the outward appearance of product is more graceful, knob lid 300 is the bellied that makes progress of perpendicular to knob 100 simultaneously, and the handheld knob lid 300 of convenient to use person upwards pulls out the knob subassembly, makes knob subassembly and regulating ring 600 separation.

As shown in fig. 2, a sleeve body 130 is disposed at a central position of the knob 100, a bayonet and other positions are disposed on the sleeve body 130, and when the knob cover is installed, a structure such as a buckle is correspondingly disposed on an inner wall of the knob cover 300, and the knob cover is installed in a buckling manner corresponding to the bayonet.

The number of the pins 610 on the adjusting ring 600 is three, and correspondingly, the number of the inserting sleeves 110 of the knob 100 in the knob assembly is three and is uniformly distributed, so that the uniform stress is ensured during connection.

The adjusting ring 600 comprises: a ring-shaped main body 601 and the pins 610 formed on the main body 601 and protruding upwards. The ring-shaped body 601 is provided for connection of the adjustment ring 600 to other parts, here primarily to the bean grinder 500.
