The technical problem to be solved by the present invention is to avoid the above-mentioned deficiencies of the prior art, and to provide a four-leaf cutter with higher efficiency and better effect of shredding food and a food blender equipped with the four-blade cutter. The technical solution proposed by the technical problem is: designing a four-blade cutter for a food mixer, mounted on a drive shaft of the stirring head, comprising a base body, and blades which are radially and evenly distributed at the root of the base body, each of the blades A straight or curved blade is provided thereon. In particular, the tool has a "ten" shape including four blades, and the cutting angle of each point on the blade of each blade satisfies the inequality of 85° > a > 16. . The blades are bent at a near root and along the central axis to form an angle of 19 ° > β > 15 with the plane of the substrate. . The cutting angle α of each point on the cutting edge is continuously gradual, and specifically, the change in the cutting angle α of each point is proportional to the distance from each point to the center of the substrate. The cutting angle of each point on the blade satisfies the inequality 40° > α > 20°.

The present invention also provides a food blender comprising a four-blade cutter mounted on a drive shaft of the agitating head, the four-blade cutter further comprising a base body, and each of the vanes having a radially evenly distributed root portion of the base body, each of the vanes A straight or curved blade is provided. In particular, the tool has a "ten" shape, including four blades, and the cutting angle of each point on the blade of each blade satisfies the inequality of 85° > α > 16. .

The vanes are bent at a near root and along the central axis to form an angle with the plane of the substrate 19 . > β > 15. .

The cutting angle α of each point on the cutting edge is continuously gradual, and specifically, the change in the cutting angle α of each point is proportional to the distance from each point to the center of the substrate.

The cutting angle of each point on the blade satisfies the inequality 40° > α > 20°.

Compared with the prior art, the invention has the beneficial effects that the four-leaf cutter chopped food has high power, high speed and good effect.

detailed description

The invention will now be further described in detail in conjunction with the drawings. Referring to Figures 1, 2 and 5, a four-blade cutter 8 for a food blender is mounted on the drive shaft 6 of the agitating head 5, including a base body 2, and is radially uniform with the base body 2 as a base. Each of the blades 1 is disposed, and each of the blades 1 is provided with a straight or curved blade 11 having a "ten" shape including four blades 1, and a cutting angle of each point on the blade 11 of each blade 1 Both satisfy the inequality 85° > o > 16. . Preferably, the cutting angle of each point on the cutting edge 11 satisfies the inequality 40. > α >20. . The cutting angle α of each point on the blade 11 is continuously gradual, and specifically, the change in the cutting angle α of each point is proportional to the distance from each point to the center of the base 2.

Referring to Figures 1, 2, 5 and 6, a food blender includes a four-blade cutter 8 mounted on a drive shaft 6 of a mixing head 5, which in turn comprises a base 2, and The base body 2 is a root portion, and each of the blades 1 is radially evenly distributed. Each of the blades 1 is provided with a straight or curved blade 11 which has a "ten" shape and includes four blades 1 each of which is The cutting angle of each point on the blade 11 satisfies the inequality of 85° > o >16. . Preferably, the cutting angle of each point on the cutting edge 11 satisfies the inequality 40° > (x >20. The cutting angle α of each point on the cutting edge 11 is continuously gradual, specifically, the cutting angle α of each point The change is proportional to the distance from each point to the center of the substrate 2.

Referring to Figures 3 and 4, each of the vanes 1 is bent at a near root portion along the central axis to form an angle of 19° > β > 15° with the plane of the base 2.

The cutting angle α is the angle between the cutting edge and the food cutting. Those skilled in the art can determine the cutting angle α according to the geometric relationship shown in Fig. 2. In Fig. 2, 10 is the stirring head guard of the four-blade cutter 8 and the mixer. A section circle located in the same geometric plane, 9 is a tangent circle that is tangent to the section circle 10 and the blade edge 11. Referring to Fig. 6, the four-blade cutter 8 is riveted to the shaft head 7, and the shaft head 7 is fixed to the drive shaft 6 by means of a reverse thread, the drive shaft 6 is mounted in the stirring head 5, and the drive shaft 6 is mounted on the motor drive head 4. Above, the motor drive head 4 is tightly fitted to the motor 3. The motor 3 rotates to drive the motor drive head 4, and the motor drive head 4 drives the drive shaft 6 to rotate, because the four-blade cutter 8 and the shaft head 7 are riveted together, and the shaft head 7 is fixed on the drive shaft 6 by the reverse thread, the motor 3 Rotate to drive the four-blade cutter 8 to rotate, so as to achieve the purpose of chopping food.
