Detailed implementation mode

[0053] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0054] As Figures 1 - 12 shown, the stirring assembly of the embodiment of the present invention includes a stirring main body 1, a fitting member 2 and a knife assembly 3. The upper end of the stirring main body 1 is adapted to be connected to the output shaft of the motor. The lower end surface of the stirring main body 1 is provided with a receiving groove 11. The outer peripheral surface and the lower end surface of the stirring main body 1 are both metal surfaces.

[0055] At least a part of the fitting member 2 is arranged in the receiving groove 11. The lower end surface of the fitting member 2 is located above the lower end surface of the stirring main body 1. The lower end surface of the fitting member 2 is provided with a fitting hole 21. The fitting member 2 is a plastic part. The knife assembly 3 is arranged on the outer periphery of the stirring main body 1.

[0056] For the stirring assembly of the embodiment of the present invention, by setting the outer peripheral surface and the lower end surface of the stirring main body as metal surfaces, it is ensured that the parts of the stirring assembly in contact with food are all metal, avoiding the problem of harmful substances released by plastic at high temperatures. Moreover, by arranging a fitting member which is specifically plastic at the bottom of the stirring main body, the friction and wear between the fitting member and the cup bottom shaft 7 are reduced, avoiding the problem of powder falling off due to their friction. Moreover, since the lower end surface of the fitting member is higher than the lower end surface of the stirring main body, the fitting member is completely located inside the fitting hole, ensuring that the parts of the stirring assembly exposed outside and in contact with food are all metal, improving the safety of food.

[0057] Specifically, as Figures 2 - 5As shown, the stirring main body 1 extends in the vertical direction, and the accommodating groove 11 is located at the lower end of the stirring main body 1 and extends upward. The knife assembly 3 is arranged on the outer periphery of the stirring main body 1, and the stirring main body 1 drives the knife assembly 3 to rotate around the vertical direction under the drive of the motor to realize the whipping of food.

[0058] Specifically, the fitting 2 is arranged in the accommodating groove 11, and the fitting 2 is in tight fit with the stirring main body 1, which increases the contact area and fitting accuracy between the fitting 2 and the stirring main body 1, making the fitting 2 stably installed in the accommodating groove 11.

[0059] Specifically, a kit 71 is arranged on the cup bottom shaft 7. After the kit 71 is in tight fit with the cup bottom shaft 7, it is fitted in the fitting hole 21, and the kit 71 has a clearance fit with the fitting hole 21. Preferably, the kit 71 is a plastic part, which reduces the friction and wear between the kit 71 and the fitting 2.

[0060] Optionally, as Figures 2 - 5 shown, the stirring main body 1 includes a sleeve assembly 12 and a bracket 13. The sleeve assembly 12 has a chamber 121 that runs through the sleeve assembly 12 in the vertical direction. The bracket 13 and the fitting 2 are sequentially arranged in the chamber 121 from top to bottom, and the outer peripheral surface of the stirring main body 1 includes the outer peripheral surface of the sleeve assembly 12.

[0061] For the stirring assembly of the embodiment of the present utility model, by providing the sleeve assembly 12 and arranging the bracket 13 and the fitting 2 in the chamber 121, the structure is simple, easy to manufacture, and cost-saving.

[0062] Specifically, the bracket 13 extends in the vertical direction, and at least part of the upper end of the bracket 13 extends out of the upper end of the chamber 121. The bracket 13 is a plastic part, which reduces the overall weight of the stirring main body 1 and saves cost.

[0063] Optionally, as Figure 2 、 Figure 4 and Figure 8 shown, the stirring main body 1 further includes a support member 14. At least part of the bracket 13 and the support member 14 are arranged in the chamber 121, and the bracket 13 and the support member 14 are sequentially abutted from top to bottom. The accommodating groove 11 is arranged on the lower end surface of the support member 14. The outer peripheral edge of the lower end surface of the support member 14 has a flange portion 141 extending outward, and the lower end surface of the flange portion 141 forms the lower end surface of the stirring main body 1. The outer peripheral surface of the stirring main body 1 further includes the outer peripheral surface of the flange portion 141.

[0064] In the stirring assembly of the embodiment of the present utility model, a support member 14 is also cooperatively arranged in the chamber 121, and the cooperating member 2 is arranged in the receiving groove 11 formed on the support member 14, which improves the strength of the stirring assembly. Moreover, the arrangement of the flange portion 141 facilitates the installation of the blade at the bottom of the stirring main body 1, and makes it difficult for food to get stuck in the gap between the support member 14 and the sleeve assembly 12, which is convenient for cleaning.

[0065] Specifically, the upper end of the support member 14 is cooperated with the lower end of the bracket 13, the support member 14 is in a tight fit with the sleeve assembly 12, and the cooperating member 2 is in a tight fit with the support member 14. The flange portion 141 extends outward along the central axis of the support member 14 and wraps the lower end of the sleeve assembly 12 to form the second end of the stirring main body 1, which improves the cooperation degree and integrity between the support member 14 and the sleeve assembly 12.

[0066] Optionally, as Figures 6 - 8 shown, the lower end of the bracket 13 is provided with a first hole 131, the support member 14 includes a support body 142 and an extension portion 143, the extension portion 143 is arranged at the upper end of the support body 142, the extension portion 143 is cooperated in the first hole 131, and the upper end surface of the support body 142 abuts against the bracket 13.

[0067] In the stirring assembly of the embodiment of the present utility model, the extension portion 143 is cooperated in the first hole 131, which improves the cooperation degree between the support member 14 and the bracket 13. The upper end of the support body 142 abuts against the bracket 13, which improves the compactness of the cooperation between the support body 142 and the bracket 13. Moreover, the structure of the support member 14 is simple, easy to manufacture, and saves costs.

[0068] Specifically, the central axis of the first hole 131 is collinear with the central axis of the extension portion 143. The extension portion 143 is arranged at the upper end of the support body 142, and the central axis of the extension portion 143 is collinear with the central axis of the support body 142, realizing the coaxial setting of the support member 14 and the bracket 13. The outer peripheral contour of the cross section of the extension portion 143 is polygonal and is cooperated in the first hole 131, and the outer peripheral contour of the cross section of the support body 142 is polygonal and is cooperated in the chamber 121, making the support body 142 not easy to rotate relative to the sleeve assembly 12. The cross-sectional area of the extension portion 143 is smaller than the cross-sectional area of the upper end of the support body 142, which improves the cooperation degree between the support member 14 and the bracket 13 and makes the stirring assembly 200 structurally compact. Specifically, the outer peripheral contours of the cross sections of both the extension portion 143 and the support body 142 are hexagons.

[0069] Optionally, as Figure 8 shown, the receiving groove 11 includes a first cavity 111 and a second cavity 112 connected in sequence from top to bottom. The cross-sectional area of the first cavity 111 is smaller than the cross-sectional area of the second cavity 112, and the upper end of the cooperating member 2 abuts against the top wall surface of the second cavity 112.

[0070] In the stirring assembly of the embodiment of the present utility model, the upper end of the fitting 2 abuts against the top wall surface of the second cavity 112, so that the fitting 2 is not easily displaced in the chamber 121, ensuring the stability of the installation of the fitting 2 in the chamber 121. The food stirred by the stirring assembly is not easily introduced into the receiving groove 11, facilitating cleaning.

[0071] Specifically, the central axes of the first cavity 111 and the second cavity 112 are collinear. The cross-sectional area of the first cavity 111 is circular, and the cross-sectional area of the second cavity 112 is polygonal. As Figure 10 shown, the fitting 2 includes a fitting body 22 and an extension section 23. The extension section 23 is provided at the upper end of the fitting body 22. The outer peripheral contour of the cross-section of the extension section 23 is circular and fits in the first cavity 111. The outer peripheral contour of the cross-section of the fitting body 22 is polygonal and fits in the second cavity 112. During the assembly process of the fitting 2, the extension section 23 can be used for guiding and positioning. Moreover, the fitting 2 is stably installed in the receiving groove 11, not easily displaced deviating from the central axis of the first cavity 111, and not easily rotated relative to the sleeve assembly 12, ensuring the structural stability of the stirring main body 1 and the safety during use.

[0072] The fitting 21 further includes an arc portion 24. The extension section 23 is an annular section. The arc portion 24 is provided at the upper end of the fitting body 22 and is located in the cavity of the extension section 23. The arc portion 24 protrudes towards the upper end of the stirring main body 1 to be adapted to the upper end surface of the fitting hole 21. In other words, the upper end surface of the fitting hole 21 is an upwardly convex arc surface and is adapted to the shape of the arc portion 21. In the embodiment of the present utility model, by providing an arc portion 23 in the annular extension section 23 that is adapted to the shape of the upper end surface of the fitting hole 21, the thickness of the fitting 1 at the top of the fitting hole 21 is reduced. During the forming process of the fitting 1, the inner wall surface of the fitting hole 21 is relatively smooth, which can reduce the friction with the cup bottom shaft 7.

[0073] Optionally, the fitting body 22 and the extension section 23 of the fitting 2 are integrally formed with the bracket 13, strengthening the connection strength of the stirring assembly 200 and making the structure of the stirring assembly 200 more stable.

[0074] Optionally, the support member 14 is a metal member.

[0075] In the stirring assembly of the embodiment of the present utility model, the support member 14 is a metal member, improving the overall strength of the stirring assembly 200, reducing the amplitude of shaking when the stirring assembly 200 stirs food, and ensuring the stability of the stirring assembly 200 when stirring food.

[0076] Optionally, as Figures 2 - 5As shown, the bracket 13 and the fitting 2 are sequentially abutted along the direction from top to bottom. At least part of the chamber 121 forms the receiving groove 11, and the outer peripheral edge of the lower end of the fitting 2 has a protruding portion 25 extending outward. Specifically, at least part of one end of the chamber 121 adjacent to the second end of the stirring main body 1 forms the receiving groove 11.

[0077] As Figure 5 shown, the stirring assembly 200 further includes a metal wrapper 4. The metal wrapper 4 at least covers the lower end face and the outer peripheral face of the protruding portion 25. The lower end face of the protruding portion 25 forms the lower end face of the stirring main body 1, and the outer peripheral face of the stirring main body 1 further includes the outer peripheral face of the protruding portion 25.

[0078] In the stirring assembly of the embodiment of the present utility model, the bracket 13 and the fitting 2 are sequentially arranged in the sleeve assembly 12, which is convenient for installation. The protruding portion 25 on the fitting 2 wraps at least part of the lower end of the sleeve assembly 12 and forms the lower end face of the stirring main body 1, which is convenient for installing a blade at the bottom of the stirring main body 1, and improves the fitting degree of the fitting 2 in the chamber 121 and the integrity of the stirring main body 1, making the fitting 2 firmly installed in the chamber 121. Moreover, the setting of the metal wrapper 4 makes the outer peripheral faces of the stirring main body 1 and the protruding portion 25 both metal faces, ensuring that the parts of the stirring assembly exposed outside and in contact with food are all metal, improving the whipping efficiency and safety of the stirring main body 1 for food, and it is not easy for food to get stuck in the gap between the fitting 2 and the sleeve assembly 12, which is convenient for cleaning.

[0079] Optionally, as Figure 12 shown, the metal wrapper 4 includes an annular plate body 41, a folding portion 42 and a cylindrical portion 43.

Moreover, the structure of the metal wrapper 4 is simple, easy to manufacture and cost-saving.

[0081] Optionally, as Figure 12 shown, a notch 431 is provided at the upper end of the cylindrical portion 43, and a part of the fitting 2 is fitted in the notch 431.

[0082] In the stirring assembly of the embodiment of the present utility model, by fitting a part of the fitting member 2 into the notch 431, the fitting degree between the fitting member 2 and the cylindrical portion 43 is improved, so that the connection between the fitting member 2 and the metal cladding 4 is firm, and the metal cladding 4 is not easily detached from the fitting member 2.

[0083] Specifically, the fitting member 2 can be formed by injection molding in a mold, so as to form a protrusion (not shown) at the notch 431 of the cylindrical portion 43 during the injection molding process, so as to fit at the notch 431 and improve the fitting degree between the fitting member 2 and the cylindrical portion 43.

[0084] Specifically, there are multiple notches 431, and the multiple notches 431 are arranged at intervals along the circumferential direction of the cylindrical portion 43, further improving the fitting degree between the fitting portion and the cylindrical portion 43, so that the cylindrical portion 43 is firmly installed on the fitting member 2, ensuring the structural strength and safety of the stirring assembly 200.
