[0028] The main machine 10 includes a housing 11, a driving device 12, a speed regulating device 13, a transmission assembly 14 and a shift mechanism 15. The driving device 12 is installed in the housing 11 and includes a driving shaft 121, and the driving shaft 121 is provided with a driving gear 122 and a first clutch 123.

[0029] The speed regulating device 13 is installed on the driving shaft 121 and cooperates with the driving gear 122 . The speed regulating device 13 includes a second clutch 131 .

[0032] The driving shaft 121 is provided with a first clutch 123, and the output end of the speed regulating device 13 is provided with a second clutch 131. The shift mechanism 15 causes the driven clutch 142 to cooperate with the first clutch 123 in the first position, or to cooperate with the second clutch 131 in the second position, so that the transmission shaft 141 outputs different rotation speeds. In this way, the user can adjust the rotation speed of the blade assembly through the shift mechanism 15, and realize the speed regulation of the stirring cup without replacing the stirring cup, thereby realizing multi-functional stirring and low product cost; and since the first clutch 123 is located on the inner side of the second clutch 131, it is beneficial to reduce the height of the main machine 10 and the structure is more compact.

The driving hole 14211 is matched with the driving section 1411, so that the transmission shaft 141 can drive the driven clutch 142 to rotate together, and the driven clutch 142 is limited by the first stopper 1412 and the second stopper 1413. The shape of the driving section 1411 can be a square cylinder or other polygonal cylinders, and the shape of the driving hole 14211 matches the shape of the driving section 1411.

The shift mechanism 15 includes a bracket 151, a shift motor 152 and a shift fork 153, wherein the shift motor 152 is fixed to the bracket 151, and the shift fork 153 is slidably disposed on the bracket 151, and the output shaft of the shift motor 152 is provided with a shift gear 154, and the shift fork 153 is provided with a shift rack 1531 and a track groove 1532, wherein the shift rack 1531 is meshed with the shift gear 154, and the convex portion 1431 is slidably disposed in the track groove 1532.

[0037] As set up above, the shift motor 152 drives the shift gear 154 to rotate, and through the cooperation between the shift gear 154 and the shift rack 1531, the shift fork 153 is displaced, so that the protrusion 1431 of the gantry 143 moves along the track groove 1532, and then the gantry 143 drives the driven clutch 142 to move up and down, and combines with the first limit member 1412 and the second limit member 1413 installed on the transmission shaft 141 to realize the switching of the driven clutch 142 between the first position limited by the first limit member 1412 and the second position limited by the second limit member 1413.

[0038] The track groove 1532 includes a first groove section extending horizontally, a second groove section extending obliquely downward from the first groove section, and a third groove section extending horizontally from the second groove section. In this way, the protrusion 1431 can slide smoothly from the first groove section to the third groove section via the second groove section, or slide from the third groove section to the first groove section via the second groove section, that is, the driven clutch 142 can switch smoothly between the first position and the second position.

[0039] like Figure 3 As shown, the inner teeth 14221 extend in the up-down direction inside the meshing body 1422, and the first clutch 123 is provided with a first tooth 1231 matching the inner teeth 14221 outside; and / or, the outer teeth 14223 extend in the up-down direction outside the meshing body 1422, and the second clutch 131 is provided with a second tooth 1311 matching the outer teeth 14223 inside.

[0041] Through the above arrangement, by providing the first guide portion 14222 and the second guide portion 14224 , the engagement reliability of the driven clutch 142 with the second clutch 131 and the first clutch 123 is improved.

[0042] In one embodiment, the speed regulating device 13 includes a ring gear 132 and a first planetary gear assembly 133, wherein the first planetary gear assembly 133 includes a first gear frame 1331 and a first planetary gear 1332 disposed on the first gear frame 1331, wherein the first planetary gear 1332 is meshed with the driving gear 122 and the ring gear 132, and the second clutch 131 is fixed to the first gear frame 1331. During use, the motor drives the driving shaft 121 to rotate, so that the driving gear 122 disposed on the driving shaft 121 drives the first planetary gear 1332 to rotate around the driving shaft 121, thereby driving the first gear frame 1331 to rotate, and the second clutch 131 rotates with the first gear frame 1331 to achieve variable speed output.

[0043] Through the above arrangement, the speed regulating device 13 realizes one-stage speed reduction through the first planetary gear assembly 133 , and has a simple structure and low cost.

During use, the motor drives the drive shaft 121 to rotate, so that the drive gear 122 arranged on the drive shaft 121 drives the first planetary gear 1332 to rotate around the drive shaft 121, and then drives the first gear rack 1331 to rotate. In this way, the center gear 135 drives the second planetary gear 1342 to rotate around the drive shaft 121 as the first gear rack 1331 rotates, and then drives the second gear rack 1341 to rotate, so that the second clutch 131 installed on the second gear rack 1341 rotates accordingly, thereby realizing variable speed output.

[0045] Through the above arrangement, the speed regulating device 13 realizes two-stage deceleration through the first planetary gear assembly 133 and the second planetary gear assembly 134, which has a simple structure and low cost. Furthermore, it can also be set to three-stage deceleration or four-stage deceleration.
