Detailed Description

Referring to fig. 2 to 4, a first embodiment of a polishing apparatus of the present invention is adapted to polish an object to be polished and is installed in a housing device (not shown) of a polishing machine (not shown). The material to be ground can be, for example, coffee beans or soybeans. Since the above-mentioned housing device is not important in this disclosure and the design technique thereof is common knowledge, the description thereof is omitted here.

The first embodiment comprises a grinding mechanism 21 and a driving mechanism 22 which are detachably assembled and connected together and are arranged in the casing device, and a positioning unit 9 which surrounds the outside of the grinding mechanism 21.

Referring to fig. 3 to 5, the grinding mechanism 21 includes an inner blade assembly 23 and an outer blade unit 8 assembled to the inner blade assembly 23.

The inner knife assembly 23 includes a grinding base 3, a handle 4 disposed on the grinding base 3, a rotating shaft unit 5 penetrating through the grinding base 3 and protruding downward from the grinding base 3 to be detachably assembled with the driving mechanism 22, a powder cleaning unit 6 sleeved on the rotating shaft unit 5 and located in the grinding base 3, and an inner knife unit 7 sleeved outside the rotating shaft unit 5 and the powder cleaning unit 6 and located in the grinding base 3.

The grinding seat 3 includes a substantially circular bottom wall 31 for the rotation shaft unit 5 to pass through, a surrounding wall 32 extending upward from the periphery of the bottom wall 31, and a plurality of protrusions 33 protruding outward from the surrounding wall 32 in the radial direction. The bottom wall 31 and the peripheral wall 32 cooperate to define a polishing volume 34. The surrounding wall 32 is formed with a powder outlet passage 321 extending transversely to communicate the grinding space 34 with the outside.

The rotating shaft unit 5 includes a rotating shaft set 51 passing through the center of the grinding seat 3, and an upper clutch member 52 assembled and connected to the rotating shaft set 51 and located below the grinding seat 3.

The rotating shaft set 51 includes a first shaft 511 and a second shaft 512, which are separately assembled together and fit with the powder cleaning unit 6 and the inner blade unit 7, and are located below and above, and a gasket 513 (see fig. 4 for illustration) disposed between the second shaft 512 and the powder cleaning unit 6.

The bottom end of the first shaft 511 is screwed with the upper clutch 52, and protrudes from the upper clutch 52 through the bottom wall 31 to the polishing space 34. The second shaft 512 is a screw rod, which is inserted through the washer 513 and can be separated from and coaxially inserted into the top end of the first shaft 511. The upper clutch 52 includes a substantially disc-shaped upper disc 521 rotatably fitted on the bottom end of the first shaft 511, and a plurality of upper teeth 522 protruding from the upper disc 521 to the driving mechanism 22.

The powder cleaning unit 6 is sleeved outside the first shaft 511 and the second shaft 512 and located between the inner cutter unit 7 and the bottom wall 31. The powder cleaning unit 6 includes a rotary plate 61 located between the inner cutter unit 7 and the bottom wall 31, a rotary column 62 protruding upward from the rotary plate 61 and sleeved outside the rotary shaft set 51, and a rubber member set 63 inserted into the rotary plate 61 and protruding downward from the rotary plate 61 and protruding toward the bottom wall 31.

The turntable 61 is substantially circular. The rotary post 62 is substantially hollow cylindrical, and is located between the rotary shaft set 51 and the inner cutter unit 7 along the radial direction, so as to be driven by the rotary shaft set 51 and drive the inner cutter unit 7 to rotate.

The adhesive member set 63 includes a plurality of adhesive sheets 631 inserted on the turntable 61. Each film 631 extends vertically, has a bottom end inserted into the turntable 61 and projecting from the turntable 61 toward the bottom wall 31, and has a width substantially extending radially from the outer edge of the turntable 61 to match with other films 631 and substantially extending like a spoke.

The inner cutter unit 7 is substantially a circular truncated cone with a vertically through center, and is sleeved outside the first shaft 511 and the second shaft 512, and the bottom end is further engaged with the rotary disc 61 of the powder cleaning unit 6 through the design of the engaging groove and the engaging block, so that the inner cutter unit can be driven to rotate by the cooperation of the rotary shaft set 51, the rotary disc 61 and the rotary column 62. The outer surface of the inner blade unit 7 is formed with a blade edge.

The outer blade unit 8 is erected on the grinding base 3 and can surround the inner blade unit 7 at intervals, and includes an outer blade base 81 erected on the top end of the grinding base 3, an outer ring blade 82 arranged in the outer blade base 81, and two positioning blocks 83 for positioning the outer ring blade 82 in the outer blade base 81.

The driving mechanism 22 includes a motor unit 221, and a lower clutch 222 assembled to the motor unit 221. The lower clutch 222 is detachably coupled to the upper clutch 52 and includes a lower disc 223 and a plurality of lower teeth 224 protruding from the lower disc 223 toward the upper clutch 52. The lower teeth 224 detachably engage the upper teeth 522 of the upper clutch 52 to allow the lower clutch 222 to drive the upper clutch 52. The motor unit 221 is engaged with the lower disc 223 through a gear and provides power for the rotation of the lower disc 223. Since the design technique of the motor unit 221 and the technique of driving the lower plate 223 are common knowledge, a detailed description thereof will be omitted.

The positioning unit 9 surrounds the polishing seat 3, and includes a positioning ring 91, a plurality of hooks 92 extending from the positioning ring 91, and a clamping block 93 extending from the positioning ring 91 radially and allowing a user to hold the finger. The positioning ring 91 is annular and surrounds the outer side of the polishing seat 3. Each hook 92 extends upward from the positioning ring 91 along the axial direction and covers the corresponding protrusion 33 of the polishing seat 3 in a substantially inverted L-shape, so that the polishing seat 3 cannot move upward and cannot be separated from the positioning unit 9.

In the operation of the first embodiment, the motor unit 221 of the driving mechanism 22 can drive the lower clutch piece 222 to rotate, and the lower clutch piece 222 can drive the upper clutch piece 52 to rotate and drive the rotating shaft set 51 assembled with the upper clutch piece 52 to rotate, so as to drive the powder cleaning unit 6 and the inner cutter unit 7 sleeved on the rotating shaft set 51 to rotate. The inner cutter unit 7 rotates to grind or further grind the material to be ground, which moves between the inner cutter unit and the outer cutter unit 82 of the outer cutter unit 8, into powder.

The ground powder is thrown out from the powder outlet channel 321 of the grinding seat 3 by the rotary disc 61 for further brewing or subsequent use. During the rotation of the turntable 61, the film 631 of the film assembly 63 can effectively sweep the residual powder on the bottom wall 31 of the grinding seat 3 into the powder outlet channel 321, so as to reduce the amount of residual powder on the bottom wall 31. In the first embodiment, the spacing distance between each film 631 and the bottom wall 31 is substantially 0.5mm, which can ensure that the turntable 61 can smoothly rotate relative to the bottom wall 31 and effectively sweep the residual powder to the powder outlet channel 321.

After the first embodiment is used for a period of time, a certain amount of residual powder still accumulates inside the grinding seat, and if a user needs to clean the grinding seat, the user only needs to separate the outer blade unit 8 from the grinding seat 3 upwards, and then unscrew the first shaft 511 relative to the second shaft 512 to separate the first shaft 511 from the second shaft 512, so that the inner blade unit 7 and the powder cleaning unit 6 can be taken out for cleaning, and meanwhile, the bottom wall 31 of the grinding seat 3 can be exposed, so that the user can clean the residual powder remained on the bottom wall 31.

Referring to fig. 6 and 7, as the aforesaid preliminary cleaning is still insufficient, since the rotating shaft unit 5 is detachably coupled to the lower clutch member 222 of the driving mechanism 22 through the upper clutch member 52, the user can first grip the clamping block 93 of the positioning unit 9 with one finger, and then rotate the polishing seat 3 with the other hand along the clockwise direction relative to the positioning unit 9, so that the protrusion 33 of the polishing seat 3 is dislocated with the hook 92 of the positioning unit 9 to assume the state shown in fig. 6, and the polishing seat 3 with other components assembled thereon can be lifted up from the positioning unit 9 through the handle 4 in the whole set as shown in fig. 7, so that the whole set of the polishing mechanism 21 is separated from the driving mechanism 22, and the polishing mechanism 21 can be put under the faucet in the whole set for cleaning, or the components can be detached for cleaning one by one as mentioned before, which is quite convenient.

In summary, the driving mechanism 22 of the polishing apparatus of the present invention can be detachably assembled and connected to the inner blade assembly 23 of the polishing mechanism 21, so that the polishing mechanism 21 can be taken out and cleaned as a whole after the inner blade assembly 23 is separated from the driving mechanism 22, thereby solving the problem of difficult cleaning.

Referring to fig. 8 and 9, a second embodiment of the polishing apparatus of the present invention is different from the first embodiment in that the upper clutch member 52 (see fig. 3) and the lower clutch member 222 (see fig. 3) are omitted from the second embodiment, the rotating shaft unit 5 omits the first shaft member 511 (see fig. 3) and the second shaft member 512 (see fig. 3) and includes only one rotating shaft member 53, and the cross section of the bottom end portion of the rotating shaft member 53 cut along the radial direction is polygonal, and can be inserted into a polygonal assembling hole 225 formed in the driving mechanism 22, so that the rotating shaft member 53 can be driven by the driving mechanism 22 and can be used for separating the polishing mechanism 21 from the driving mechanism 22 in a whole set.

The above description is only an embodiment of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
