[0019] Figure 3 It is an enlarged view of part A of an embodiment of the present utility model. Specific Embodiments

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] See Figures 1 - 3, this food blender includes a main body 1. Inside the main body 1, there is a driving motor 2, a first stirring blade 3, and a second stirring blade 4. The first stirring blade 3 includes a first blade member 31 and a stirring blade column 32. The second stirring blade 4 includes a second blade member 41 and a stirring blade tube 42. The stirring blade tube 42 is sleeved outside the stirring blade column 32, and the vertical positions of the stirring blade tube 42 and the stirring blade column 32 can overlap, so as to save the overall space position.

[0022] The first blade member 31 and the second blade member 41 are respectively arranged on the stirring blade column 32 and the stirring blade tube 42 and are vertically staggered from each other. There is a first transmission component group between the driving motor 2 and the stirring blade column 32, and a second transmission component group between the stirring blade tube 42 and the first transmission component group. The first transmission component group can drive the stirring blade column 32 and the first blade member 31 to rotate in the forward direction. The first transmission component group can drive the stirring blade tube 42 and the second blade member 41 to rotate in the reverse direction through the second transmission component group. The first blade member 31 and the second blade member 41 rotate in the forward and reverse directions respectively, so that the food can receive opposite acting forces, and the first blade member 31 and the second blade member 41 can better act on the food respectively, thereby making the stirring effect better.

[0023] Further, the first transmission component includes a first transmission gear 51, the second transmission component includes a second transmission gear 52 and a transfer transmission part 53. The first transmission gear 51 is respectively in transmission connection with the driving motor 2 and the stirring blade column 32. The transfer transmission part 53 is respectively in transmission cooperation with the first transmission gear 51 and the second transmission gear 52. The second transmission gear 52 rotates in the opposite direction to the first transmission gear 51 and is fixedly connected to the stirring blade tube 42. While the first transmission gear 51 drives the stirring blade column 32 to rotate forward, it can also drive the second transmission gear 52 to rotate in the reverse direction through the transfer transmission part 53, so that the first blade member 31 and the second blade member 41 rotate in the forward and reverse directions respectively.

[0024] Further, the first transmission gear 51, the second transmission gear 52 and the transfer transmission part 53 are all bevel gear structures. The transfer transmission part 53 meshes with the first transmission gear 51 and the second transmission gear 52 respectively. As an equivalent transformation, the first transmission gear 51, the second transmission gear 52 and the transfer transmission part 53 can also be in transmission connection through a combination of a circular gear and a rack. The bevel gear structures of the first transmission gear 51, the second transmission gear 52 and the transfer transmission part 53 can better utilize the space position between the first transmission gear 51 and the second transmission gear 52, thereby further optimizing the volume of the product.

[0025] Further, an output gear 21 is provided at the transmission end of the drive motor 2. A toothed ring 6 is provided on the outer peripheral side of the output gear 21. A plurality of planetary gears 7 are connected between the toothed ring 6 and the output gear 21. The planetary gear 7 has a planetary rotating shaft 71. The planetary rotating shaft 71 is movably connected to the first transmission gear 51. The speed of the planetary gear 7 revolving around the output gear 21 is less than the speed of the output gear 21 rotating on its own. Generally, the rotational speed of the drive motor 2 is relatively high. By the cooperation of the planetary gear 7 with the output gear 21 and the toothed ring 6, the planetary gear 7 can revolve around the output gear 21 while rotating on its own, thereby driving the first transmission gear 51 to rotate at a relatively slow speed.

[0026] Further, a plurality of transfer transmission parts 53 are provided between the first transmission gear 51 and the second transmission gear 52. The transfer transmission parts 53 are evenly distributed along the circumferential direction, making the circumferential force on the first transmission gear 51 and the second transmission gear 52 more uniform, which can better improve the stability of the rotation process of the two and is not easy to deviate.

[0027] Further, a gearbox housing 8 is fixedly connected inside the main body 1. The gearbox housing 8 can facilitate the installation of the second transmission gear 52 and the transfer transmission parts 53.

[0028] A limiting flange 81 is provided on the inner side of the gearbox housing 8 corresponding to the second transmission gear 52. A positioning bearing 9 is provided between the inner side of the second transmission gear 52 and the limiting flange 81, making the rotation of the second transmission gear 52 more stable and making it not easy for the stirring cutter tube 42 to interfere with the stirring cutter post 32.

[0029] Further, a limiting step 321 is provided on the outer side of the stirring cutter post 32. The bottom of the stirring cutter tube 42 is arc-shaped. The bottom of the stirring cutter tube 42 abuts against the limiting step 321 and is in sliding fit with each other. The limiting step 321 can play a role in positioning the installation between the stirring cutter post 32 and the stirring cutter tube 42. The bottom of the stirring cutter tube 42 is arc-shaped, enabling it to better slide with the limiting step 321.

[0030] Further, a limiting convex column 11 is provided on the inner side of the bottom of the main body 1. The bottom of the stirring cutter post 32 is provided with a limiting slot 322 corresponding to the limiting convex column 11. The limiting convex column 11 is inserted into and in sliding fit with the limiting slot 322, improving the stability of the rotation of the stirring cutter post 32.

[0031] The above embodiments are only the preferred solutions of the present invention, and the present invention may also have other implementation solutions. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope set by the claims of this application.
