The methods in the following embodiments, unless otherwise specified, are conventional methods in the field. The components or equipment in the following embodiments, unless otherwise specified, are universal standard parts or components known to those skilled in the art, and their structures and principles are known to those skilled in the art through technical manuals or conventional experimental methods.

[0026] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the following detailed description, for ease of explanation, many specific details are described to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the utility model discloses a stirring assembly, including a stirring shaft 1, an upper stirring blade 2, a lower stirring blade 3, an upper sleeve 4, a lower sleeve 5, a limiting sleeve 6, a clamping member 7 and a fastener 8. The upper sleeve 4 and the lower sleeve 5 are sequentially sleeved on the outside of the stirring shaft 1 from top to bottom. The bottom end of the clamping member 7 is provided with a clamping ring 701 which surrounds the outer wall of the clamping member 7 in the circumferential direction, and the top of the clamping member 7 is detachably fixedly connected to the bottom end of the stirring shaft 1 through the fastener 8. The limiting sleeve 6 is sleeved on the outside of the clamping member 7 and is located in the lower sleeve 5. The upper stirring blade 2 is sleeved on the outside of the limiting sleeve 6 and is clamped between the bottom end of the upper sleeve 4 and the top end of the lower sleeve 5. The lower stirring blade 3 is sleeved on the outside of the limiting sleeve 6 and is clamped between the bottom end of the lower sleeve 5 and the top of the clamping ring 701.

[0028] The lower stirring blade 3 and the upper stirring blade 2 are respectively provided with a plurality of blades, and the number of blades 301 of the lower stirring blade is n. b With upper mixing blade 201 quantity n t Satisfies the following relationship: n b -n t ≥2.

[0029] Through the structural design of the stirring shaft 1, the upper sleeve 4, the lower sleeve 5, the limiting sleeve 6, the pressing member 7 and the fastener 8, the upper stirring blade 2 and the lower stirring blade 3 are clamped at different heights respectively, and only one fastener 8 is needed to form a stable limit of the upper stirring blade 2 and the lower stirring blade 3 relative to the stirring shaft 1, which is convenient for disassembly and assembly. In addition, the number of blades 301 of the lower stirring blade is at least two more than the number of blades 201 of the upper stirring blade. The upper stirring blade 2 mainly performs coarse crushing of the food, and the smaller number of blades helps to quickly cut the food. The lower stirring blade 3 mainly performs further fine crushing and mixing of the coarsely crushed food. The larger number of blades increases the contact area between the food and the blades, and improves the crushing and mixing efficiency. Therefore, with the upper stirring blade 2 and the lower stirring blade 3 at different heights, a higher crushing and mixing efficiency of the food can be achieved.

[0030] In this embodiment, in order to better achieve the limit between the stirring shaft 1 and the upper sleeve 4, as shown in FIG. Figure 3 As shown, a limiting ring 101 is provided on the upper part of the stirring shaft 1 and surrounds the outer wall of the stirring shaft 1 in the circumferential direction. A limiting groove 102 is provided at the bottom of the limiting ring 101. The top end of the upper sleeve 4 is located in the limiting groove 102 and abuts against the bottom wall of the limiting groove 102.

[0031] In this embodiment, in order to improve the connection stability between the clamping piece 7 and the bottom of the stirring shaft 1, a first groove 103 is provided at the bottom of the stirring shaft 1, and the cross-sectional shape of the inner wall of the first groove 103 matches the cross-sectional shape of the outer wall of the clamping piece 7, and the top end of the clamping piece 7 is located in the first groove 103.

[0032] In this embodiment, the detachable fixed connection between the fastener 8 and the stirring shaft 1 is specifically achieved through the following structure: a fastening hole 104 extending along the axial direction of the stirring shaft 1 is provided at the bottom of the first groove 103, and the fastener 8 is detachably fixedly connected to the stirring shaft 1 through the fastening hole 104.

[0033] In this embodiment, in order to facilitate the installation of the fastener 8 and ensure the installation stability of the fastener 8, a second groove 702 is provided at the bottom of the pressing member 7, and the fastener 8 has a cut-off end 801 and a joint end 802. The cut-off end 801 of the fastener 8 abuts against the bottom wall of the second groove 702, and the joint end 802 of the fastener 8 penetrates the bottom wall of the second groove 702 and extends into the fastening hole 104 at the bottom of the stirring shaft 1. For example, when the fastener 8 is a bolt, an internal thread is provided in the fastening hole 104 to cooperate with the external thread of the bolt portion, and the head of the bolt abuts against the bottom wall of the second groove 702.

[0034] In this embodiment, in order to improve the connection stability of each component, the middle of the upper stirring blade 2 and the middle of the lower stirring blade 3 are respectively provided with mounting holes 202, and the cross-sectional shapes of the inner wall of the first groove 103, the cross-sectional shapes of the outer wall of the pressing member 7, the cross-sectional shapes of the inner wall of the limiting sleeve 6, and the cross-sectional shapes of the mounting holes 202 are all matching polygons, and the relative rotation that may occur in each component is prevented by the coordination of the structures of the sides of the polygon. In this embodiment, a hexagonal cross-sectional shape is selected. Of course, in other embodiments, other polygonal cross-sectional shapes such as pentagons and heptagons can also achieve this purpose.

[0035] In this embodiment, the blades 201 of the upper stirring blade 2 are arranged evenly in the circumferential direction around the middle of the upper stirring blade 2, and the blades 301 of the lower stirring blade 3 are arranged evenly in the circumferential direction around the middle of the lower stirring blade 3. In order to further improve the crushing and stirring effects, as Figure 4 As shown, the edge angle of the blade 201 of the upper stirring blade is inclined from the bottom of the blade to the top surface of the blade, and the area of ​​the bottom of the blade is larger than the area of ​​the top of the blade. Figure 5 As shown, the edge angle of the blade 301 of the lower stirring blade is inclined from the top of the blade to the bottom surface of the blade, and the top area of ​​the blade is larger than the bottom area of ​​the blade. In this way, the upper stirring blade 2 and the lower stirring blade 3 form a shearing crushing and stirring effect, and the staggered blade arrangement is also conducive to the mixing of the stirred ingredients.

[0036] In this embodiment, considering the stirring resistance, power consumption, and noise vibration, the number of blades 201 of the upper stirring blade is n. t = 2, number of blades 301 of the lower mixing knife n b =4.

[0037] The embodiment of the utility model further discloses a supplementary food machine, comprising the above-mentioned stirring assembly.
