It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] like Figure 1-3 As shown, the embodiment of the present application proposes a grinding cup, including an outer cup body 1, an upper cover 2 covering the outer cup body 1, an inner cup body 3 embedded in the outer cup body 1, a PCB board and a driving motor 4 arranged in the outer cup body 1, a transmission wheel 5 fixed on the output shaft of the driving motor 4, a rotation-stopping device 6 connecting the outer cup body 1 and the inner cup body 3, a grinding knife group 7 fixed to the inner cup body 3 and matched with the transmission wheel 5, and a safety trigger device 8 installed on the outer cup body 1 and electrically connected to the PCB board. The driving motor 4 is electrically connected to the PCB board. When making dishes or other things, a lot of spices or other dry materials are used, and sometimes these need to be Some materials are ground into powder, and manual grinding is not very convenient, hands are sore and the efficiency is low. If the material, such as chili powder, is touched, it may cause human discomfort. If the powdered material is purchased specifically, additional storage space is required. The present application includes the outer cup body 1 and the inner cup body 3 embedded in the inner and outer cups, and the anti-rotation device 6 limits the relative rotation of the outer cup body 1 and the inner cup body 3. The upper cover 2 is closed and the safety trigger device 8 is pressed to release the lock to prevent accidental touch. The drive motor 4 then drives the transmission wheel 5 to rotate, thereby driving the grinding knife group 7 to rotate in the inner cup body 3 to grind the object. It has a simple structure and a small size, occupies a small space, is easy to place, and is suitable for household grinding.

[0019] The outer cup body 1 includes a cup body 11, and a base 12 and a sleeve cup 13 sleeved on both ends of the cup body 11, the sleeve cup 13 is arranged on a receiving groove 14 on the side facing the inner cup body 3, the anti-rotation device 6 is arranged at the bottom of the receiving groove 14, the drive motor 4 is fixed on the side of the sleeve cup 13 facing the base 12, and the grinding cup also includes a shock absorbing device 9 connecting the sleeve cup 13 and the drive motor 4, wherein the sleeve cup 13 is provided with fixed columns 15 on both sides of one end facing the base 12, and the first fixed column 15 is also provided with a reinforcing rib 16 on the side thereof, and the drive motor Connecting blocks 41 are provided on both sides of the machine 4 corresponding to the first fixing column 15, and an opening 42 is provided on the connecting block 41. The first fixing column 15 is provided with an air avoidance groove 17 corresponding to the connecting block 41. The shock absorbing device 9 includes a shock absorbing ring clamped on the opening 42. The cross-sectional shape of the shock absorbing ring is set in an "I" shape. The screws connect the connecting block 41 and the first fixing column 15 through the shock absorbing ring, and the opening 42 is clamped on both sides of the connecting block 41, which can ensure the fixing strength. At the same time, the elastic silicone can effectively absorb shock and slightly adjust the eccentric position to adapt to the operation of the cup holder assembly.

[0020] The inner cup body 3 includes a cup body 31, a cup seat 32, a connecting column 33 protruding from the cup body 31 on the side facing the cup seat 32, a mounting column 34 corresponding to the connecting column 33 and the mounting column 34, and a threaded hole 35 corresponding to the connecting column 33 and the mounting column 34. The cup body 31 and the cup seat 32 are respectively provided with a through hole 36 for installing the grinding knife set 7. The traditional hardware cup has a through hole punched at the bottom, and the stainless steel screw is locked to the knife seat from the inside of the cup. Due to the problems of offset and processing deviation of the screw holes in the large cup, food residues will be accumulated after use, and the surface of the screw head may be scratched when it is washed by hand, etc., which is a poor user experience. The screws are exposed in the cup, affecting the appearance. If the material is abnormal, it will also affect food safety. The present application fixes them with screws on the outside. After the modification, the interior of the large cup is smooth, complete, beautiful, and easy to clean. It also completely solves the abnormal water seepage from the screw holes caused by the screws not being properly driven.

[0021] The anti-rotation device 6 includes a circular ring 61 protruding from the cup holder 32 on the side facing the base 12, a partition plate provided on the circumferential side of the bottom of the accommodating groove 14, and a groove 62 provided on the circular ring 61 corresponding to the partition plate, so as to limit the rotation of the inner cup body 3 and reduce the influence on the grinding knife group 7.

[0022] The safety trigger device 8 includes a micro switch 81 fixed in the outer cup body 1 and electrically connected to the PCB board, a connecting rod 82 longitudinally arranged in the outer cup body 1, a second fixing column 83 protruding on the side of the connecting rod 82 facing the micro switch 81, and a spring 84 sleeved on the second fixing column 83 and respectively abutting against the connecting rod 82 and the micro switch 81. The upper cover 2 presses the connecting rod 82 downward to compress the spring 84, so that the second fixing column 83 presses the micro switch 81 to release the safety lock, which is safer.

[0023] The grinding knife group 7 includes a blade 71, a rotating column 72 inserted on the blade 71, a rotating wheel 73 connected to the other end of the rotating column 72 and matched with the transmission wheel 5, a bearing 74 sleeved on the rotating column 73, and a shell 75 wrapped around the outer side of the bearing 74 and integrally injection-molded with the bearing 74. The shell 75 is made of high-temperature resistant and wear-resistant plastic, which reduces the molding difficulty and defect rate of traditional hardware grinding cups. In addition, due to the small size and simple shape of the small hardware sleeve, the cost is effectively controlled to ensure dimensional accuracy, and the yield rate of the pressed oil-containing bearing components is effectively improved, avoiding the abnormalities such as the traditional integrated hardware cup pressing bearing easily scratching the surface of the large cup or deforming under force. At the same time, the bearing 74 and the shell 75 are integrally molded to ensure dimensional accuracy and ensure that the hardware and plastic are completely integrated and no residue or water seepage occurs. The outer layer is wrapped in plastic, which effectively isolates the heat generated by the high-speed rotation of the knife, giving a good warm feel when the user touches it for cleaning.

[0024] As described above, one or more implementation methods are provided in combination with specific contents, and the specific implementation of this application is not limited to these descriptions. Any similarity or similarity with the method, structure, etc. of this application, or some technical deductions or replacements made based on the concept of this application should be considered as the protection scope of this application.
