An assembly gap is formed between the first bearing seat 2 and the second bearing seat 9, and the transmission input member 1 is sleeved with a transmission gear 4 in the area of ​​the assembly gap.

[0043] One end of the bridge shaft 5 and the middle of the stirring main shaft 7 are respectively rotatably assembled on the second bearing seat 9; the bridge gear 6 is sleeved on the proximal end of the other end of the bridge shaft 5; the stirring gear 8 is sleeved on the proximal end of the stirring main shaft 7 close to one end of the first bearing seat 2;

The first bearing seat 2 and the second bearing seat 9 can well limit the transmission input member 1, the bridge shaft 5 and the mixing main shaft 7, so that stable transmission can be carried out between the transmission input member 1, the bridge shaft 5 and the mixing main shaft 7, effectively avoiding the noise caused by the shaking of the motor shaft and improving the user experience; moreover, the above structure is simple, reasonably utilizes space, and reduces the overall volume of the mixing transmission structure, thereby reducing the overall volume of the food mixer and reducing the space occupied by the food mixer.

[0046] In actual application, the external power mechanism drives the transmission input member 1 to rotate with its own axis as the rotation axis, so that the transmission input member 1 drives the transmission gear 4 to rotate; since the transmission gear 4 is engaged with the bridge gear 6, and at the same time, the bridge gear 6 is engaged with the internal teeth of the inner ring gear 3, and the stirring gear 8 is engaged with the internal teeth of the inner ring gear 3, the transmission gear 4 drives the bridge gear 6 to rotate with the bridge shaft 5 as the rotation axis, and drives the inner ring gear 3 to rotate with its own axis as the rotation axis, and then drives the stirring main shaft 7 to rotate with its own axis as the rotation axis through the inner ring gear 3 through the stirring gear 8, thereby realizing the rotation of the stirring main shaft 7, and the stirring main shaft 7 can be connected to the stirring rod 105 to achieve the purpose of stirring food.

[0047] Specifically, the transmission input member 1 includes a transmission shaft 11 and a transmission wheel 12;

[0048] The transmission wheel 12 is sleeved on one end of the transmission shaft 11, and the outer wall of the transmission wheel 12 is transmission-connected to the external power mechanism;

[0049] The middle portion of the transmission shaft 11 is rotatably assembled on the first bearing seat 2 , the other end of the transmission shaft 11 is rotatably assembled on the second bearing seat 9 , and the transmission gear 4 is sleeved on the transmission shaft 11 .

[0050] The external power mechanism is specifically a motor and a transmission belt. A transmission belt can be installed on the outside of the transmission wheel 12. The transmission belt is driven by the motor to rotate, thereby driving the transmission shaft 11 and the transmission wheel 12 to rotate, and then driving the transmission shaft 11 through the transmission of the inner ring gear 3, the bridge gear 6 and the stirring gear 8.

[0051] With the above structure, a belt drive device can be used, and the belt drive can reduce noise and vibration, run more smoothly, and further reduce the generation of noise.

[0053] The bearing seat body 21 is provided with a mounting groove 20 on one side facing the second bearing seat 9. The size of the mounting groove 20 is adapted to the size of the inner gear ring 3, and the inner gear ring 3 is embedded in the mounting groove 20.

[0054] One end of the first connecting tube 22 is arranged on the side of the bearing seat body 21 facing away from the second bearing seat 9. A through hole is provided in the middle of the bearing seat body 21, and the through hole connects the first connecting tube 22 and the mounting groove 20.

[0055] The reinforced angle plate 23 is circumferentially distributed on the first connecting tube 22 with the axis of the first connecting tube 22 as the center axis, and one side of the reinforced angle plate 23 is connected to the side wall of the first connecting tube 22, and the bottom of the reinforced angle plate 23 is connected to the bearing seat body 21; the first connecting tube 22 is provided with at least one first bearing 24, and the transmission shaft 11 is rotatably assembled with the first connecting tube 22 through the first bearing 24.

[0056] At least one first bearing 24 is provided in the first connecting cylinder 22 for rotationally assembling with the transmission shaft 11, and the bearing seat body 21 serves to position the inner gear ring 3, so as to facilitate better combined installation of the first bearing seat 2, the inner gear ring 3 and the second bearing seat 9.

[0057] The reinforcing angle plate 23 serves to reinforce the first connecting tube 22 , providing additional support and stability, and maintaining the stability of the overall structure of the first bearing seat 2 .

[0058] Furthermore, the transmission input member 1 also includes a fixing nut 13, a connecting rod 14 is provided at one end of the transmission shaft 11, the side wall of the connecting rod 14 is provided with a thread, and the radius of the connecting rod 14 is smaller than the radius of the transmission shaft 11; a connecting hole 15 with a diameter matching the connecting rod 14 is provided in the middle of the transmission wheel 12, one end of the transmission shaft 11 passes through the connecting hole 15 and is threadedly connected to the fixing nut 13.

[0059] With the above structure, the fixing nut 13 and the connecting rod 14 are threadedly connected. Since the radius of the connecting rod 14 is smaller than the radius of the transmission shaft 11, one end of the connecting rod 14 is tightly against the outer periphery of the connecting hole 15, thereby fixing the transmission shaft 11 and the transmission wheel 12. The above structure is simple and easy to install.

[0060] Specifically, the second bearing seat 9 includes a base plate 91 and a second connecting tube 92. The base plate 91 is provided with a first assembly hole 93, a second assembly hole 94, and a third assembly hole 95.

The second connecting cylinder 92 serves to protect and support the stirring shaft 7. Since the stirring shaft 7 is required to stir food and is relatively long, the stirring shaft 7 is strengthened to enable it to drive the stirring rod 105 to stir foods with high viscosity or heavy weight.

[0064] Preferably, an oil seal 97 is further provided in the first assembly hole 93 , the second assembly hole 94 and the second connecting tube 92 , respectively. The oil seal 97 is located on the side of the second bearing 96 facing away from the first bearing seat 2 .
