DETAILED DESCRIPTION

[0030] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also include elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprising a ..." do not exclude the presence of other identical elements in the process, method, article or equipment comprising the elements. The term "two or more" includes two or more than two cases.

[0032] The present application provides a stirring device, which may include a handheld blender or other types of blenders, which are not limited here.

[0033] The stirring device is described below by taking a hand-held blender as an example. The stirring device includes a stirring component 10 and a stirring cup. Ingredients can be placed in the stirring cup, and the stirring component 10 is suitable for extending into the stirring cup to stir the ingredients.

[0034] Please refer to Figure 1 The stirring assembly 10 includes a cover body 1 and a stirring blade 2.

[0035] The stirring blade 2 is rotatably arranged in the cover body 1 so as to whip the food by the rotation of the stirring blade 2, and the cover body 1 can protect the stirring blade 2 on the outside of the stirring blade 2 to avoid damage to the stirring blade 2 caused by direct contact between the stirring blade 2 and the stirring cup.

[0036] Please refer to Figure 2 The minimum distance from the peripheral wall 11 of the cover body 1 to the rotation axis L of the stirring blade 2 is R2, the maximum distance from the stirring blade 2 to the rotation axis L is R1, and the ratio of R2 to R1 is greater than or equal to 1.07 and less than or equal to 1.3.

[0037] For example, the ratio of R2 to R1 is 1.08, or the ratio of R2 to R1 is 1.1, or the ratio of R2 to R1 is 1.15, or the ratio of R2 to R1 is 1.2. When the ratio of R2 to R1 satisfies the above value range, the interference between the stirring blade 2 and the peripheral wall 11 of the cover body 1 can be avoided, and the suction force between the stirring component 10 and the stirring cup when beating the food can be reduced, thereby reducing the vibration of the stirring device and further reducing the difficulty of operating the stirring component 10.

[0038] In this way, when using the stirring device, the user does not need to hold the stirring cup in one hand and the stirring component 10 in the other hand. Instead, the user can place the stirring cup on the table and use the stirring device by holding the stirring component 10 with one hand, thereby reducing the difficulty of operating the stirring device. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the whipped ingredients splashing to the outside of the stirring cup.

[0039] According to the stirring component 10 of the embodiment of the present application, by limiting the ratio of the minimum distance from the peripheral wall 11 of the cover body 1 to the rotation axis L of the stirring blade 2 to the maximum distance from the stirring blade 2 to the rotation axis L to be greater than or equal to 1.07 and less than or equal to 1.3, the suction between the stirring component 10 and the stirring cup when whipping the ingredients is reduced, thereby reducing the vibration of the stirring device and further reducing the difficulty of operating the stirring component 10. The reduction in the suction between the stirring component 10 and the stirring cup can reduce the risk of the whipped ingredients splashing to the outside of the stirring cup.

[0040] In some embodiments, please refer to Figure 3 and Figure 4 The cover body 1 includes: an end wall 12 and a peripheral wall 11, the peripheral wall 11 is arranged on the end wall 12, and the end wall 12 and the peripheral wall 11 form an accommodating space 13. The rotating shaft 3 is rotatably arranged on the end wall 12, and at least part of the rotating shaft 3 is located in the accommodating space 13. The mixing blade 2 is connected to the rotating shaft 3 and is located in the accommodating space 13. In this way, the mixing blade 2 can rotate around the rotating shaft 3, that is, the axis of the rotating shaft 3 is the rotation axis L of the mixing blade 2.

[0041] In some embodiments, please refer to Figure 1 Along the direction around the rotation axis L, the peripheral wall 11 of the cover body 1 includes a connected recessed portion 111 and a raised portion 112, wherein the recessed portion 111 can be recessed in the radial direction of the rotation axis 3 toward the direction close to the rotation axis 3, and the raised portion 112 can be raised in the radial direction of the rotation axis 3 toward the direction away from the rotation axis 3, and in the radial direction of the rotation axis 3, the distance from the recessed portion 111 to the rotation axis L is smaller than the distance from the raised portion 112 to the rotation axis L.

[0042] In this way, the distance from the recessed portion 111 to the rotation axis L is different from the distance from the raised portion 112 to the rotation axis L, so that the suction forces between the recessed portion 111 and the raised portion 112 and the mixing cup are different, so as to reduce the average suction force between the mixing component 10 and the mixing cup when mixing the ingredients. In this way, the vibration of the mixing device is reduced, thereby reducing the difficulty of operating the mixing component 10. The reduction in the suction force between the mixing component 10 and the mixing cup can reduce the risk of the ingredients being mixed splashing to the outside of the mixing cup.

[0043] In the implementation mode in which the peripheral wall 11 includes a connected recessed portion 111 and a raised portion 112, since the distance from the recessed portion 111 to the rotation axis L is smaller than the distance from the raised portion 112 to the rotation axis L, the minimum distance from the peripheral wall 11 to the rotation axis L of the mixing blade 2 is the minimum distance from the recessed portion 111 to the rotating shaft 3, that is, the ratio of the minimum distance from the recessed portion 111 to the rotating shaft 3 to the maximum distance from the mixing blade 2 to the rotation axis L is greater than or equal to 1.07 and less than or equal to 1.3.

[0044] In this way, interference between the stirring blade 2 and the recessed portion 111 can be avoided, and the suction force between the stirring component 10 and the stirring cup when stirring the ingredients can be reduced. This makes it easier to reduce the vibration of the stirring device, thereby reducing the difficulty of operating the stirring component 10. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the stirred ingredients splashing to the outside of the stirring cup.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The number of the protrusions 112 and the number of the recesses 111 are both plural, and along the direction around the rotation axis L, the recesses 111 and the protrusions 112 are alternately arranged.

[0046] That is to say, multiple recessed portions 111 and multiple raised portions 112 are alternately arranged along the direction around the rotation axis L, and since the distance from the recessed portion 111 to the rotation axis L is smaller than the distance from the raised portion 112 to the rotation axis L, the distance from the recessed portion 111 to the rotation axis L is different from the distance from the raised portion 112 to the rotation axis L.

[0047] In this way, when the stirring component 10 beats the food, the suction forces between the multiple recessed portions 111 and the multiple raised portions 112 can be made different, so as to reduce the average suction force between the stirring component 10 and the stirring cup when beating the food. In this way, the vibration of the stirring device is reduced, thereby reducing the difficulty of operating the stirring component 10. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the beaten food splashing to the outside of the stirring cup.

[0048] For example, the number of the raised portions 112 and the number of the recessed portions 111 are both 2, or the number of the raised portions 112 and the number of the recessed portions 111 are both 3, or the number of the raised portions 112 and the number of the recessed portions 111 are both 5, or the number of the raised portions 112 and the number of the recessed portions 111 are both 6. Preferably, the number of the raised portions 112 and the number of the recessed portions 111 are both greater than or equal to 5.

[0049] In some embodiments, please refer to Figure 1When the number of the raised portions 112 and the number of the recessed portions 111 are both five, the five raised portions 112 and the five recessed portions 111 are equidistantly distributed along the direction around the rotation axis L. This makes it easy to reduce the average suction force between the stirring component 10 and the stirring cup when whipping the food. This makes it easy to reduce the vibration of the stirring device, thereby reducing the difficulty of operating the stirring component 10. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the food being whipped splashing to the outside of the stirring cup.

[0050] In some embodiments, please refer to Figure 5 In the extension direction of the rotating shaft 3, the ratio of the distance between the connection between the stirring blade 2 and the rotating shaft 3 and the end wall 12 to the minimum distance from the end of the peripheral wall 11 away from the end wall 12 to the end wall 12 is greater than or equal to 0.5 and less than or equal to 0.6.

[0051] For example, please refer to Figure 5 In the extension direction of the rotating shaft 3, the distance between the connection between the stirring blade 2 and the rotating shaft 3 and the end wall 12 is H1, and the minimum distance between the end of the peripheral wall 11 away from the end wall 12 and the end wall 12 is H2. The ratio of H1 to H2 is greater than or equal to 0.5 and less than or equal to 0.6. For example, the ratio of H1 to H2 is 0.5, or the ratio of H1 to H2 is 0.53, or the ratio of H1 to H2 is 0.55, or the ratio of H1 to H2 is 0.56, or the ratio of H1 to H2 is 0.6.

[0052] When H1 and H2 are within the above-mentioned range of values, the distance between the connection point of the stirring blade 2 and the rotating shaft 3 and the end wall 12 is smaller than the distance between the connection point of the stirring blade 2 and the rotating shaft 3 and the end of the peripheral wall 11 away from the end wall 12, thereby facilitating the reduction of the average suction force between the stirring component 10 and the stirring cup when whipping the food. This facilitates reducing the vibration of the stirring device and thereby reducing the difficulty of operating the stirring component 10. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the food being whipped splashing to the outside of the stirring cup.

[0053] In some embodiments, please refer to Figure 5 The peripheral wall 11 is provided with a pressure relief port 113, which connects the accommodating space 13 with the space outside the peripheral wall 11. Thus, by providing the pressure relief port 113, when the stirring assembly 10 is stirring the food, some pressure can be released through the pressure relief port 113, thereby reducing the suction force between the stirring assembly 10 and the stirring cup when stirring the food. This helps to reduce vibration of the stirring device and further reduce the difficulty of operating the stirring assembly 10. In addition, the reduction in suction force between the stirring assembly 10 and the stirring cup can reduce the risk of the stirred food splashing outside the stirring cup.

[0054] In some implementations, the pressure relief port 113 may be a circumferentially closed opening, or the pressure relief port 113 may be open toward an end of the peripheral wall 11 away from the bottom wall, both of which can achieve the same technical effects as the above effects and are not limited here.

[0055] For example, in the implementation method in which the peripheral wall 11 includes a connected recessed portion 111 and a raised portion 112, please refer to 4. The pressure relief port 113 can be provided in the recessed portion 111 and open toward the end of the peripheral wall 11 away from the bottom wall. In this way, when the stirring component 10 is whipping the food, part of the pressure can be released through the pressure relief port 113, thereby reducing the suction force between the stirring component 10 and the stirring cup when whipping the food. In this way, it is convenient to reduce the vibration of the stirring device, thereby reducing the difficulty of operating the stirring component 10. The reduction in the suction force between the stirring component 10 and the stirring cup can reduce the risk of the whipped food splashing to the outside of the stirring cup.

[0056] Please refer to Figure 5 The diameter of the pressure relief port 113 gradually increases in the direction of the peripheral wall 11 away from the end wall 12, so that the pressure relief effect of the pressure relief port 113 can gradually increase to adapt to the pressure changes at different positions on the peripheral wall 11.

[0057] In some embodiments, please refer to Figure 6 The end of the peripheral wall 11 away from the end wall 12 is the outer end. In the direction perpendicular to the end wall 12, the ratio of the maximum distance between the inner wall and the outer end of the pressure relief port 113 to the maximum distance from the outer end to the end wall 12 is greater than or equal to 0.2 and less than or equal to 0.3.

[0058] For example, if Figure 6 As shown, in a direction perpendicular to the end wall 12, the maximum distance between the inner wall and the outer end of the pressure relief vent 113 is H3, and the maximum distance between the outer end and the end wall 12 is H4. The ratio of H3 to H4 is greater than or equal to 0.2 and less than or equal to 0.3. For example, the ratio of H3 to H4 is 0.2, or the ratio of H3 to H4 is 0.22, or the ratio of H3 to H4 is 0.25, or the ratio of H3 to H4 is 0.28, or the ratio of H3 to H4 is 0.3. That is, when the ratio of H3 to H4 falls within the above value range, the pressure relief vent 113 can be ensured to have a good pressure relief effect. When the stirring assembly 10 is stirring the food, some pressure can be released through the pressure relief vent 113, thereby reducing the suction between the stirring assembly 10 and the stirring cup when stirring the food. At the same time, the pressure relief vent 113 is positioned relatively close to the outer end, which helps to reduce the design difficulty of the pressure relief vent 113.

[0059] In some embodiments, please refer to Figures 1-6 A flange structure 114 is formed at one end of the peripheral wall 11 away from the end wall 12 .

[0060] It should be noted that when the stirring component 10 is stirring the food in the stirring cup, the edge thickness of the peripheral wall 11 away from the end wall 12 is usually thinner, and when the end of the peripheral wall 11 away from the end wall 12 contacts the bottom wall of the stirring cup, it is very easy to scratch the bottom wall of the stirring cup. Even if too much force is applied, the stirring component 10 will pierce the stirring cup.

[0061] Therefore, in the present application, a flange structure 114 is formed at the end of the peripheral wall 11 away from the end wall 12. In this way, the flange structure 114 can protect the bottom wall of the blending cup, thereby reducing the risk of the end of the peripheral wall 11 away from the end wall 12 scratching the bottom wall of the blending cup, and even reducing the risk of the blending component 10 piercing the blending cup.

[0062] In an implementation in which the peripheral wall 11 includes a recessed portion 111 and a raised portion 112 connected to each other, and the recessed portion 111 is provided with a pressure relief port 113, an end of the raised portion 112 away from the end wall 12 protrudes beyond an end of the recessed portion 111 away from the end wall 12. Therefore, a flange structure 114 can be provided at an end of the raised portion 112 away from the end wall 12 to reduce the risk of the end of the raised portion 112 away from the end wall 12 scratching the bottom wall of the blending cup, or even reduce the risk of the blending assembly 10 piercing the blending cup.

[0063] In some embodiments, please refer to Figure 7 A first convex surface 1141 is formed on the side of the flange structure 114 facing away from the end wall 12 .

[0064] Therefore, when the flange structure 114 contacts the bottom wall of the blending cup, it can contact the bottom wall of the blending cup through the first convex surface 1141, thereby increasing the contact area between the flange structure 114 and the bottom wall of the blending cup, so as to reduce the risk of the blending component 10 piercing the blending cup, and the first convex surface 1141 is relatively smooth, which helps to reduce the risk of the blending component 10 scratching the bottom wall of the blending cup.

[0065] In some embodiments, please refer to Figure 7 The flange structure 114 is bent in a direction away from the accommodating space 13 .

[0066] Therefore, when the flange structure 114 and the peripheral wall 11 are integrally formed, the two can be demoulded together, thereby reducing the difficulty of setting the flange structure 114 and helping to reduce production costs.

[0067] In some embodiments, please refer to Figure 7 A second convex surface 1142 is formed on the side of the flange structure 114 facing away from the accommodating space 13 .

[0068] Therefore, when the flange structure 114 contacts the side wall of the blending cup, it can contact the side wall of the blending cup through the second convex surface 1142, thereby increasing the contact area between the flange structure 114 and the side wall of the blending cup, which is beneficial to reducing the risk of the blending component 10 scratching the side wall of the blending cup.

[0069] In some embodiments, please refer to Figure 1 and Figure 3 The stirring assembly 10 further includes a handle 4, which may include a columnar structure or a square structure, etc., which is not limited here, wherein the handle 4 is connected to the cover body 1. Thus, it is convenient for the user to hold the handle 4 to hold the stirring assembly 10.

[0070] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0071] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
