Referring to fig. 1, a stirring blade assembly 10b includes a blade holder 1b, a ball bearing 2b, a bearing washer 3b, and a blade shaft 4 b. The assembly mode of the cutter shaft 4b, the ball bearing 2b and the cutter frame 1b is transition fit. This type of fit has the following disadvantages: 1) when the stirring knife is subjected to irregular resistance of fluid in the stirring working process, the reaction forces with different sizes and directions impact on the ball bearing 2b and the knife rest 1b to generate noise; 2) a gap exists between the bearing washer 3b and the ball bearing 2b up and down, and the bearing washer moves up and down in work; thereby generating a loud noise and affecting the user experience.

In order to solve at least one of the above problems, embodiments of the present application disclose a stirring blade assembly 10. The configuration of the blender blade assembly 10 is described in detail below.

Referring to fig. 2 and 5, a stirring blade assembly 10 includes a blade holder 1, a bearing 2, an upper damping member 3, and a lower damping member 4. The stirring blade assembly 10 in some embodiments further comprises a shaft sleeve 5, a cutter head 6, a sealing member 7, a cutter shaft 8, a blade assembly 9, an upper gasket 101, a lower gasket 102 and the like, and the assembly of the components with the tool rest 1, the bearing 2 and the like can adopt any structure. The tool holder 1 comprises a bearing mounting cavity 13. The structure of the tool holder 1 is not limited. The bearing mounting cavity 13 is used for mounting the bearing 2, and the structure is not limited. The bearing 2 is located in the bearing mounting cavity 13. The structure of the bearing 2 is not limited, for example, a ball bearing, etc. The cooking machine comprises a cutter shaft 8 assembled with the bearing 2. The arbor 8 passes bearing installation cavity 13 is connected with the motor of cooking machine host computer and the blade subassembly 9 of stirring knife tackle spare, and from this, the motor rotates and can drive blade subassembly 9 and rotate, realizes stirring function. The upper damper 3 is located between the top end of the bearing 2 and the inner wall of the bearing installation cavity 13. The upper damping member 3 serves to space the bearing 2 from the tool holder 1, thereby performing a damping function, and its structure is not limited. The lower damping piece 4 is located between the bottom end of the bearing 2 and the inner wall of the bearing installation cavity 13, separates the bottom end of the bearing 2 from the tool rest 1, plays a role in damping, and is not limited in structure.

So set up, because go up damper 3 and damper 4 separate the top and the bottom of bearing 2 respectively with knife rest 1, play the cushioning effect, after arbor 8 received the irregular reaction force of fluid, arouse bearing 2 (for example ball bearing) and knife rest 1 between the striking each other, go up the damping member 3 and the very big buffering effort between each other of damper 4's design down to play the effect of noise abatement, with this improvement user experience.

With reference to fig. 2 and 3, in one embodiment, the stirring blade assembly includes a shaft sleeve 5 sleeved on the bearing 2, and at least one of the upper damping member 3 and the lower damping member 4 is in interference connection with the shaft sleeve 5. The interference magnitude of the interference connection may vary depending on the particular product. So set up, interference connection make bearing 2 with go up damping part 3 or damping part 4 is connected closely down, avoids avoiding bearing 2 play about working mutually, under some circumstances, also can avoid bearing 2 and arbor 8 play from top to bottom, and the shock attenuation is effectual.

The structure of the tool holder 1 is not limited, the tool holder 1 comprises an upper tool holder 11 and a lower tool holder 12, and the upper tool holder 11 and the lower tool holder 12 are welded. In the case where the tool holder 1 includes the upper tool holder 11 and the lower tool holder 12, the upper tool holder 11 and the lower tool holder 12 have an upper cavity and a lower cavity, respectively, whereby the upper cavity and the lower cavity constitute the bearing mounting cavity 13 after the upper tool holder 11 and the lower tool holder 12 are welded together. So set up, owing to be upper slitter 11 and lower knife rest 12 with 1 split of knife rest, can compress tightly upper slitter 11 and lower knife rest 12 among the welding process, and then compress tightly the part in bearing installation cavity 13, from this, each part equipment is inseparable, avoids the play from top to bottom in the work, can not produce the noise because of vibrations at the stirring in-process, stirring sword subassembly 10 is little at the noise of work, improves user experience.

Referring to FIG. 3 in conjunction with FIG. 2, in one embodiment, the upper tool holder 11 and the lower tool holder 12 are sleeved with each other to a depth H1, H1 is 1mm or more and 5mm or less, such as 1mm, 2mm, 3mm, 4mm or 5 mm. So set up, go up knife rest 11 and lower knife rest 12 processing convenience and processing cost are low, and the equipment is firm, and the inserted degree of depth is enough, and the concentricity is good.

With continued reference to fig. 2, in one embodiment, the stirring blade assembly 10 includes a blade disc 6. The upper tool rest 11 and the lower tool rest 12 are welded with the cutter head 6, and the welding position is shown by a circle 61 in fig. 2 and 3. So set up, can be so that to be connected closely between the part between blade disc 6 and the knife rest 1, can reduce the noise because of vibrations produce, in addition, realize making the connection structure between upper knife rest 11, lower knife rest 12 and the blade disc 6 simple through welding process, in addition, the welding can also play sealed effect, saves seal structure. Under the condition that cooking machine has the heating function, blade disc 6 can be for heating the dish subassembly, and under the condition that cooking machine does not have the heating function, blade disc 6 can only have the function of installation blade subassembly 9.

Referring to fig. 2 and 4, in one embodiment, the upper shock absorbing member 3 includes a first shock absorbing portion 31 and a second shock absorbing portion 32. The first and second damping

portions

31 and 32 are sleeved with the shaft sleeve 5. The first and

second dampers

31 and 32 constitute a step 33. The step 33 includes an inner step surface 331 attached to the sleeve 5 and an outer step surface 332 attached to the inner wall of the bearing installation cavity 13. With the arrangement, in the welding process, the area separated between the bearing 2 and the tool rest 1 is larger by the step 33, and the damping effect is better. At the same time, the step 33 provides a point of force for the bearing 2 to be compressed between the upper damper 3 and the lower damper 4.

Referring to fig. 2, in one embodiment, the lower damping member 4 is provided with a positioning groove 41, and the shaft sleeve 5 is located in the positioning groove 41. So set up, fix a position through constant head tank 41 axle sleeve 5, be convenient for axle sleeve 5 in the installation with damper 4 compresses tightly down.

Continuing to refer to fig. 2, in one embodiment, a metal member 42 is embedded in the lower damping member 4. The metal member 42 may be bent to have a plurality of bent portions, or may have a flat plate shape. So set up, metalwork 42 has strengthened the hardness of damper 4 down to, have better shock attenuation effect, for example, because damper 4 sets up the hardness reinforcing behind the metalwork 42 down, bearing 2 is difficult to take place the swing at the rotation in-process, also can not reach the cushioning effect because too hard, consequently, can reach the effect of noise reduction after addding metalwork 42. The skilled person will understand that the lower damping member 4 may be provided with both the metal member 42 and the positioning groove 41.
