As a common kitchen appliance for household meat grinders, the meat grinder is used to process meat into granular meat fillings, which is convenient for families to make sausages, meat fillings, meatballs and other foods. It is widely used because it is convenient and quick. When the meat grinder is operating, the meat grinder assembly is mainly connected to the drive assembly, so that the drive assembly drives the meat grinder assembly to work, so as to realize the meat grinder operation. Existing meat grinders generally use a multi-stage gear transmission method to achieve deceleration to increase torque, but usually a single gear is used to transmit the force to the next gear to achieve the transmission of driving force, and finally the driving force is transmitted to the shaft sleeve, and the shaft sleeve drives the stirring rod to rotate. In this case, the strength will be relatively low. In addition, the stirring rod is generally connected to the shaft sleeve by a screw. If used for a long time, the screw is easy to loosen under vibration. The above two situations will cause the existing meat grinder to be unstable during operation and prone to failure.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figure 1-12 As shown, a meat grinder comprises a transmission reduction module 1, a stirring module 2 and a clamping module 3; like Figure 1-4 As shown, the transmission reduction module 1 includes a motor 11, a primary transmission mechanism 12, a secondary transmission mechanism 13, an internal gear cover 14 and a sleeve 15; the primary transmission mechanism 12 includes a primary driving gear 121 and a primary driven gear set, the primary driving gear 121 is fixedly connected to the output shaft of the motor 11, and the primary driving gear 121 is transmission-connected to the primary driven gear set; the secondary transmission mechanism 13 includes a secondary driving gear set and a secondary driven gear 131, and the secondary driven gear 131 is transmission-connected to the sleeve 15 is fixedly connected, the secondary driving gear set is drivingly connected with the secondary driven gear 131; wherein the rotating shaft of the primary driving gear 121 and the rotating shaft of the secondary driven gear 131 are in a non-contact state; thereby avoiding the rotating shaft of the primary driving gear 121 and the rotating shaft of the secondary driven gear 131 from interfering with each other; the primary transmission mechanism 12 and the secondary transmission mechanism 13 are both arranged in the internal gear cover 14, and the primary driven gear set and the secondary driving gear set are both meshed with the internal teeth in the internal gear cover 14; like Figure 5 and 6 As shown, the stirring module 2 includes a shell 21 and a stirring rod 22, the stirring rod 22 is arranged in the shell 21, and an insertion mechanism 23 is arranged on one side of the shell 21; the snap-on module 3 includes a snap-on shell 31 and a screw-on mechanism 32; the insertion mechanism 23 extends into the snap-on shell 31, and a screw-on mechanism 32 is movably arranged inside the snap-on shell 31, and the screw-on mechanism 32 is snapped with the insertion mechanism 23, and the shaft sleeve 15 is arranged inside the screw-on mechanism 32, and a connecting head 221 is provided at one end of the stirring rod 22 close to the screw-on mechanism 32, and the connecting head 221 is connected to the shaft sleeve 15.

[0018] In the meat grinder, the motor 11 drives the primary driving gear 121 to rotate, and the primary driving gear 121 can drive the gears in the primary driven gear set to rotate, thereby driving the inner gear cover 14 to rotate through the meshing structure. After the inner gear cover 14 rotates, the gears in the secondary driving gear set can be driven to rotate through the meshing structure, and then the secondary driven gear 131 can be driven to rotate, and finally the shaft sleeve 15 is driven to rotate through the secondary driven gear 131, and the shaft sleeve 15 is used to drive the stirring rod 22 to rotate.

Then, when the motor 11 drives the shaft sleeve 15 to rotate through the primary transmission mechanism 12 and the secondary transmission mechanism 13, the stirring rod 22 can be driven to rotate. Moreover, since the connection is realized by the snap-on connection between the insertion mechanism 23 and the screw-on mechanism 32, it is not easy to loosen during operation compared with the connection method of screws. In this way, the transmission reduction module 1, the stirring module 2 and the snap-on module 3 are structurally matched, so as to improve the stability of the meat grinder during operation, thereby reducing the failure rate of the meat grinder.

By adopting the clamping method to quickly position and fix the two, the assembly process of the meat grinder can be simplified, the assembly efficiency can be improved, and the situation that the screws of the meat grinder vibrate and loosen during operation can be avoided, which can effectively ensure the tightness of the connection between the two and ensure the normal use of the meat grinder.

In this embodiment, the sleeve 15 is rotationally connected to the secondary upper cover 133, and the secondary driven gear 131 is also rotationally connected to the secondary upper cover 133. After the rotating shaft of the secondary driven gear 131 passes through the secondary upper cover 133, it is fixedly connected to the sleeve 15, and when the secondary driven gear 131 rotates, it can drive the sleeve 15 to rotate.

[0023] Optional, such as Figure 2 and 3 As shown, a first support rod 125 is provided on the lower surface of the primary upper cover 123, and the first support rod 125 extends in the direction of the primary lower cover 124, and the length of the first support rod 125 is greater than the thickness of the primary driving gear 121 and the thickness of the primary driven gear 122; by providing the first support rod 125, it can be ensured that there is enough height between the primary upper cover 123 and the primary lower cover 124 to accommodate the primary driving gear 121 and the primary driven gear 122, and ensure that the primary driving gear 121 and the primary driven gear 122 can stably rotate between the primary upper cover 123 and the primary lower cover 124; like Figure 2 and 4 As shown, a second support rod 135 is provided on the lower surface of the secondary upper cover 133, and the second support rod 135 extends in the direction of the secondary lower cover 134, and the length of the second support rod 135 is greater than the thickness of the secondary driving gear 132 and the thickness of the secondary driven gear 131.

[0024] Specifically, Figure 5 , 7As shown in Figures 8 and 9, a hollow tube 311 is provided at the center of the snap-on shell 31, so that a cavity is formed between the inner wall of the snap-on shell 31 and the outer wall of the hollow tube 311, and a plug-in port 312 is provided on the side of the snap-on shell 31 close to the insertion mechanism 23, and the plug-in port 312 is located on the outer side of the hollow tube 311 and communicates with the cavity, and the screw-on mechanism 32 is provided in the cavity and sleeved on the outer wall of the hollow tube 311, and the screw-on mechanism 32 is rotatably connected to the hollow tube 311; The insertion mechanism 23 includes a shaft cylinder 231 and a snap-on boss 232. The shaft cylinder 231 is arranged at one end of the outer shell 21 close to the snap-on shell 31, and the snap-on boss 232 is arranged on the outer wall of the shaft cylinder 231. The snap-on boss 232 cooperates with the plug-in port 312 so that the snap-on boss 232 passes through the plug-in port 312 and extends into the snap-on shell 31, and the snap-on boss 232 is snap-on with the screw-on mechanism 32, and at the same time, the connecting head 221 of the stirring rod 22 passes through the hollow tube 311 and is connected to the sleeve 15.

[0025] By providing the insertion port 312 , the snap-fitting boss 232 can be conveniently inserted into the cavity, and a corresponding screw-fastening mechanism 32 is provided in the cavity to cooperate with the snap-fitting boss 232 , so that the stirring module 2 and the snap-fitting module 3 are clamped to each other.

When the snap-on ring 322 rotates, the abutment assembly 326 can be driven to move back and forth along the guide groove 314, so that the snap-on ring 322 can be guided.

[0032] It is worth noting that if Fig.12As shown, the abutment assembly 326 includes a mounting block 3261, a spring member 3262 and a ball 3263. The mounting block 3261 is arranged in the clamping ring 322. The spring member 3262 is arranged on the surface of the mounting block 3261 and extends in the direction of the guide groove 314 after passing through the clamping ring 322. The end of the spring member 3262 close to the guide groove 314 is provided with a ball 3263, and the ball 3263 is movably arranged in the guide groove 314. When the clamping ring 322 rotates, it can drive the mounting block 3261 and the spring member 3262 to move, so that the ball 3263 at one end of the spring member 3262 can move back and forth along the guide groove 314, so as to realize the guidance of the clamping ring 322 and avoid the situation that the clamping ring 322 is offset when rotating. By providing the spring member 3262, the ball 3263 can be kept in the guide groove 314 and will not fall off.
