[0035] The conventional meat grinder can only meet the demand of mincing meat due to the low speed and high torque output of motor;The grinding machine needs high speed and low torque, and usually more than 10000 rpm to efficiently crush grains, beans and other materials, and the two need to be purchased separately due to the difference in output characteristics. Figure 5 And Figure 6 As shown, the meat grinder motor is installed on the top of the bowl cover assembly, the output shaft 710 of the planetary reduction gear box in the meat grinder motor is drivingly assembled with the input shaft 410 of the acceleration gear set 400, and the output shaft of the acceleration gear set is drivingly assembled with the blade assembly;Through the acceleration gear set 400 in the bowl cover assembly 300 of the device, the low speed output of the meat grinder motor can be converted into the high speed required by the blade assembly 200, so that the meat grinder has the function of grinding without additional motor, avoids the repeated investment of users and reduces the waste of resources.
[0036] As shown, Figure 2 And Figure 3 The bowl cover assembly 300 includes an upper cover 310 and a lower cover 320;
[0037] The upper cover 310 is provided with a rotating shaft 210 hole in the center, the input shaft 410 of the acceleration gear set 400 is rotatably installed in the rotating shaft 210 hole of the upper cover 310, the lower cover 320 is buckled on the upper cover 310, and the acceleration gear set 400 is contained in the space of the upper cover 310 and the lower cover 320.
[0038] The output shaft 420 of the acceleration gear set 400 forms a closed space by buckling the upper cover 310 and the lower cover 320, contains the acceleration gear set 400, can effectively isolate the dust and debris of the crushed materials in the bowl 100 and external oil stains and water vapor, avoid impurities from invading the gear set to affect the transmission accuracy or cause component wear, and at the same time provide accurate installation positioning structure for the input shaft 410 and the output shaft 420 of the acceleration gear set 400, to ensure the stability of gear meshing transmission.
[0039] As shown, Figure 3 And Figure 4As shown, the acceleration gear set 400 includes an input gear 430, an intermediate gear 440, and a transmission gear 450;
[0040] The input gear 430 includes a rotating disc part 431 and an inner ring part 432, the center of the rotating disc part 431 is fixedly installed on the input shaft 410, and the inner ring part 432 is fixedly installed on the bottom surface of the rotating disc part 431;
[0041] The center of the lower cover 320 is provided with a shaft hole for installing the output shaft 420, the output shaft 420 is rotatably installed at the center of the lower cover 320, and the part of the output shaft 420 located on the lower cover 320 is fixedly installed with the transmission gear 450;
[0042] The lower cover 320 is provided with a shaft seat for installing the intermediate gear 440, and the intermediate gear 440 is installed on the shaft seat;
[0043] The inner ring of the input gear 430 is engaged with the intermediate gear 440, and the intermediate gear 440 is engaged with the transmission gear 450.
[0044] Through the transmission structure composed of the inner ring of the input gear 430, the intermediate gear 440, and the transmission gear 450, a stable multi-stage speed increasing path is constructed. The input gear 430 receives the low-speed power of the meat grinder motor, which is transmitted to the transmission gear 450 through the intermediate gear 440, and finally drives the blade assembly 200 through the output shaft 420, which can efficiently convert the low-speed and high-torque output of the meat grinder into the high-speed and low-torque required for grinding (adapted to the grinding requirement of more than 10,000 rpm / min), ensuring that grains, beans and other materials can be efficiently ground, solving the core problem that traditional meat grinders cannot be ground.
[0045] As shown in FIG. 4, Figure 2 It also includes an oil-impregnated bearing 500, which is arranged in the rotating shaft 210 hole of the upper cover 310 in the form of insert molding;
[0046] The input shaft 410 is installed in the oil-impregnated bearing 500 in an axial limiting manner, and the input shaft 410, the rotating disc part 431, and the inner ring part 432 are an integral molding structure. In use, it is driven to rotate by the planetary gear box output shaft of the meat grinder motor;
[0047] The oil-impregnated bearing 500 has self-lubricating properties and is fixed in the rotating shaft 210 hole of the upper cover 310 in the form of insert molding, which can provide stable and smooth rotation support for the input shaft 410, reduce frictional resistance and wear during high-speed rotation of the input shaft 410; at the same time, the axial limiting design ensures that the input shaft 410 will not deviate axially during rotation, ensuring the precise engagement of the input gear 430 and the intermediate gear 440.
[0048] As shown in FIG. 4, Figure 2As shown, a cutter shaft mounting position is provided in the center of the bottom of the bowl 100;

The coupling 230 and the output shaft 420 are a disengageable transmission assembly.
[0050] The blade shaft mounting position in the middle of the bottom of the feeding bowl 100 provides precise positioning support for the rotating shaft 210, preventing the rotating shaft 210 from shifting during high-speed rotation. The blade 220 is fixedly mounted on the rotating shaft 210 and can rotate stably and synchronously with the rotating shaft 210, avoiding uneven crushing caused by blade 220 wobbling. At the same time, the rotating shaft 210 and the output shaft 420 of the acceleration gear set 400 are driven by a coupling 230, ensuring that the high-speed power after acceleration is stably transmitted to the blade 220, further ensuring the crushing efficiency of materials such as grains and beans.
[0051] In addition, the rotating part of the cutter shaft is provided with an oil-impregnated bearing 500 by means of insert molding.

[0053] In addition, the input shaft 410 is provided with a coupler.
[0054] As the connecting component between the input shaft 410 and the output end of the meat grinder motor, the coupler can compensate for possible installation deviations between the two. Through its own buffering and centering effect, it ensures that the motor power is stably transmitted to the input shaft 410 of the acceleration gear set 400.
[0055] In addition, the rim of the bowl 100 is provided with two outwardly extending fastening protrusions, and the outer side of the bowl lid assembly 300 is provided with a fastening groove corresponding to the fastening protrusions;
[0056] After the bowl lid assembly 300 is placed over the material bowl 100, the bowl lid assembly 300 is rotated to make the fastening groove and the fastening protrusion fasten together.
[0057] The locking mechanism, which allows for rotation after the lid is closed, eliminates the need for complicated alignment or forceful operation. Users simply place the lid assembly 300 onto the bowl 100 and gently rotate it to secure it. To disassemble, simply rotate it in the opposite direction.
[0058] In addition, a base is fixedly installed at the bottom of the material bowl 100.
