[0008] In some embodiments, the cutter head body is further provided with a receiving groove, the receiving groove is located in the mounting groove, the third connecting hole passes through the receiving groove and the mounting groove in sequence, and the first gasket is located in the receiving groove.

[0009] In some embodiments, the thickness of the connecting piece is equal to the depth of the mounting groove, and the thickness of the first gasket is equal to the depth of the receiving groove.

[0010] In some embodiments, the blade assembly further includes a second gasket;

[0011] The cutter shaft includes a first connecting section and a second connecting section, which are coaxially connected.

[0012] The second gasket has a sixth connecting hole, and the second gasket is sleeved on the first connecting segment through the sixth connecting hole and abuts between the second connecting segment and the connecting piece;

[0013] The second connector is sequentially inserted into the third, fourth, fifth, and sixth connecting holes to connect the cutter head body, the first gasket, and the cutter shaft.

[0014] In some embodiments, the cutter head assembly further includes a bushing, the second connecting section passing through the bushing, and a positioning block provided on the outer surface of the bushing.

[0015] In some embodiments, a locking hole is provided at the end of the second connecting segment away from the first connecting segment;

[0032] Please refer to Figures 1 to 4 An embodiment of this utility model provides a cutter head assembly 100, including a cutter head body 10, a connecting piece 20, and a cutter shaft 30;

[0033] The cutter head body 10 has a mounting groove 12 on one side, the connecting piece 20 is engaged in the mounting groove 12, the connecting piece 20 has a mounting hole 22, the connecting piece 20 is sleeved on the cutter shaft 30 through the mounting hole 22, and the hardness of the connecting piece 20 is greater than the hardness of the cutter head body 10.

[0034] In this embodiment, when the blade assembly 100 is applied to a juicer, the blade shaft 30 can be connected to the base drive, and the base can drive the blade shaft 30 to rotate. The connecting piece 20 is installed on the blade shaft 30 through the mounting hole 22, and the connecting piece 20 can also be installed on the blade body 10 through the mounting groove 12. When the blade body 10, blade shaft 30, etc. are damaged, it is convenient to replace and repair them. Moreover, since the blade body 10 and blade shaft 30 are assembled through the connecting piece 20, injection molding is not required, thereby reducing the manufacturing cost of the blade assembly 100. Since the hardness of the connecting piece 20 is greater than that of the blade body 10, the connecting piece 20 is used to directly connect the blade body 10 and blade shaft 30 instead of the blade body 10. Compared with the connection method of the metal blade shaft 30 being encased in plastic blades through injection molding, the harder connecting piece 20 has better wear resistance and stronger resistance to bending deformation, thereby improving the strength of the blade assembly 100 and extending its service life.

[0035] In some specific embodiments, when the cutter head body 10 is engaged in the mounting groove 12, an interference fit is formed between the cutter head body 10 and the groove wall of the mounting groove 12, thereby fixing the cutter head body 10 and the connecting piece 20 relatively. The cutter head body 10 can be made of plastic material, that is, the cutter head body 10 can be a plastic cutter head, which can reduce the manufacturing cost of the cutter head assembly 100. Both the connecting piece 20 and the cutter shaft 30 can be made of metal material, that is, the cutter shaft 30 can be a metal cutter shaft 30, and the connecting piece 20 can be a metal connecting piece 20. For example, both the connecting piece 20 and the cutter shaft 30 can be made of stainless steel, which has good wear resistance and hardness, as well as good corrosion and rust resistance.

[0036] In some embodiments, the cutter head assembly 100 further includes a first connector 40, the connecting piece 20 having a first connecting hole 24, the cutter head body 10 having a second connecting hole 14, the second connecting hole 14 being located within the mounting groove 12, and the first connector 40 passing through the first connecting hole 24 and the second connecting hole 14 to connect the connecting piece 20 and the cutter head body 10.

[0037] In this embodiment, by providing a first connector 40 and having the first connector 40 sequentially pass between the first connecting hole 24 and the second connecting hole 14, the connection strength between the connecting piece 20 and the cutter head body 10 can be further improved.

[0038] In some specific embodiments, the first connector 40 can be a screw, the first connecting hole 24 can be a through hole, and the second connecting hole 14 can be a threaded hole. There can be two first connectors 40, and correspondingly, two first connecting holes 24 and two second connecting holes 14. The two first connecting holes 24 are located on both sides of the mounting hole 22, and the two second connecting holes 14 are located on both sides of the mounting groove 12. This arrangement makes the force between the connecting piece 20 and the cutter head body 10 more balanced, resulting in higher connection strength.

[0039] In some embodiments, the cutter head assembly 100 further includes a second connector 50 and a first washer 60. The hardness of the first washer 60 is greater than the hardness of the cutter head body 10. The cutter head body 10 has a third connecting hole 16 that penetrates the mounting groove 12. The first washer 60 is located between the connector 20 and the cutter head body 10. The first washer 60 has a fourth connecting hole 62. The width of the cutter shaft 30 is greater than the diameter of the fourth connecting hole 62. The cutter shaft 30 has a fifth connecting hole 32 at one end near the cutter head body 10. The second connector 50 is sequentially inserted into the third connecting hole 16, the fourth connecting hole 62, and the fifth connecting hole 32 to connect the cutter head body 10, the first washer 60, and the cutter shaft 30.

[0040] In this embodiment, the second connector 50, inserted between the third connecting hole 16, the fourth connecting hole 62, and the fifth connecting hole 32, connects the cutter head body 10, the first washer 60, and the cutter shaft 30 into a single unit, resulting in a stronger connection between the cutter shaft 30 and the cutter head body 10. Because the hardness of the first washer 60 is greater than that of the cutter head body 10, the first washer 60 exhibits better wear resistance and resistance to bending deformation. By using the first washer 60, direct contact between the end of the cutter shaft 30 and the cutter head body 10 is avoided, thereby reducing wear on the cutter head body 10 and extending its service life.

[0041] In some specific embodiments, the first gasket 60 is annular. The first gasket 60 can be a metal gasket. The second connector 50 can be a bolt, pre-supported, the third connecting hole 16 can be a through hole, and the fourth connecting hole 62 can be a threaded hole.

[0042] In some embodiments, the cutter head body 10 is further provided with a receiving groove 18, the receiving groove 18 is located in the mounting groove 12, the third connecting hole 16 passes through the receiving groove 18 and the mounting groove 12 in sequence, and the first gasket 60 is located in the receiving groove 18.

[0043] In this embodiment, the receiving groove 18 is used to receive the first gasket 60. The receiving groove 18 also has the function of limiting the first gasket 60, which can prevent the first gasket 60 from shifting.

[0044] In some embodiments, the thickness of the connecting piece 20 is equal to the depth of the mounting groove 12, and the thickness of the first gasket 60 is equal to the depth of the receiving groove 18.

[0045] In this embodiment, by setting it up in this way, it is possible to avoid the first gasket 60, connecting piece 20, etc., from interfering with each other and creating gaps, making the overall structure of the cutter head assembly 100 more compact and further improving the overall strength of the cutter head assembly 100.

[0046] In some embodiments, the blade assembly 100 further includes a second gasket 70;

[0047] The cutter shaft 30 includes a first connecting section 34 and a second connecting section 36, which are coaxially connected. The diameter of the first connecting section 34 is smaller than the diameter of the second connecting section 36. The fifth connecting hole 32 is located at the end of the first connecting section 34 away from the second connecting section 36.

[0048] The second gasket 70 has a sixth connecting hole 72. The second gasket 70 is sleeved on the first connecting segment 34 through the sixth connecting hole 72 and abuts against the second connecting segment 36 and the connecting piece 20.

[0049] The second connector 50 is sequentially inserted into the third connecting hole 16, the fourth connecting hole 62, the fifth connecting hole 32 and the sixth connecting hole 72, so as to connect the cutter head body 10, the first gasket 60 and the cutter shaft 30.

[0050] In this embodiment, the second gasket 70 replaces the second connecting segment 36 in direct contact with the connecting piece 20, which increases the force-bearing area and thus increases the connection strength between the connecting piece 20 and the cutter shaft 30. The second connector 50, passing through the third connecting hole 16, the fourth connecting hole 62, the fifth connecting hole 32, and the sixth connecting hole 72, can connect the cutter head body 10, the first gasket 60, the second gasket 70, and the cutter shaft 30 into a single unit.

[0051] In some specific embodiments, the first connecting segment 34 and the second connecting segment 36 can be integrally formed.

[0052] In some embodiments, a locking hole 362 is provided at one end of the second connecting segment 36 away from the first connecting segment 34.

[0053] In this embodiment, by providing a locking hole 362, it can be snapped together with the output shaft of the motor in the machine base. The rotation of the motor can drive the second connecting section 36 to rotate, thereby sequentially driving the first connecting section 34, the connecting piece 20 and the cutter head body 10 to rotate.

[0054] In some specific embodiments, a positioning groove is provided on the inner wall of the card hole 362, and a positioning protrusion is provided on the output shaft of the motor. The positioning groove and the positioning protrusion cooperate to enable the output shaft of the motor to drive the second connecting section 36 to rotate.

[0055] In some embodiments, a first limiting surface 342 is provided on the side of the first connecting segment 34, and a second limiting surface 222 is provided on the side wall of the mounting hole 22. The first limiting surface 342 and the second limiting surface 222 cooperate to prevent the first connecting segment 34 and the mounting hole 22 from rotating relative to each other.

[0056] In this embodiment, the first limiting surface 342 and the second limiting surface 222 cooperate to prevent the first connecting segment 34 and the connecting piece 20 from rotating relative to each other, thereby enabling the connecting piece 20 and the cutter head body 10 to rotate.

[0057] In some embodiments, the cutter head assembly 100 further includes a bushing 80, the second connecting segment 36 passing through the bushing 80, and a positioning block 82 provided on the outer surface of the bushing 80.

[0058] In this embodiment, the bushing 80 is snapped onto the mounting plate at the bottom of the feed cup by the positioning block 82, making it easy to install and remove. The second connecting section 36 passes through the bushing 80, and the bushing 80 has a limiting effect on the second connecting section 36, allowing the second connecting section 36 to rotate smoothly within the bushing 80.

[0059] In some embodiments, the cutter shaft 30 further includes a third connecting segment 38, which is connected to the end of the second connecting segment 36 away from the first connecting segment 34. The diameter of the second connecting segment 36 is smaller than the diameter of the third connecting segment 38, and the locking hole 362 passes through the second connecting segment 38.

[0060] The bushing 80 has a first receiving hole 84 and a second receiving hole 86. The first receiving hole 84 and the second receiving hole 86 are coaxially arranged. The diameter of the first receiving hole 84 is smaller than the diameter of the second receiving hole 86. The second connecting section 36 passes through the first receiving hole 84, and the third connecting section 38 passes through the second receiving hole 86.

[0061] In this embodiment, the first receiving hole 84 is used to receive the second connecting segment 36, and the second receiving hole 86 is used to receive the third connecting segment 38. When installing the cutter shaft 30, the first connecting segment 34, the second connecting segment 36, and the third connecting segment 38 are sequentially passed through the first receiving hole 84 and the second receiving hole 86, with the first connecting segment 34 passing through the first receiving hole 84, the second connecting segment 36 reaching into the first receiving hole 84, and the third connecting segment 38 reaching into the second receiving hole 86. This arrangement provides a limiting effect on the cutter shaft 30, allowing it to be quickly installed into the bushing 80.
