Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a mixer. Background Technology

[0002] The blades of existing blenders are usually arranged in multiple rows along the length of the shaft. This arrangement of blades does not blend food finely enough. In addition, when crushing shaved ice or ice cubes, there are problems such as uneven crushing and obvious particles. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a mixer with good cutting and crushing performance.

[0004] To achieve the above objectives, this utility model discloses a mixer, comprising a cup body and a cup base, wherein the cup body is detachably connected to the cup base, and the cup body and the cup base cooperate to form a mixing chamber; the cup base is provided with a blade, and the blade is placed in the mixing chamber; characterized in that: the blade includes a rotating shaft and two first blades, two second blades, two third blades, and two fourth blades disposed on the rotating shaft; the first blade has a first bent portion at its end away from the rotating shaft, and the second blade has a second bent portion at its end away from the rotating shaft; both the first bent portion and the second bent portion bend away from the cup base, and the angle between the first bent portion and the first blade is not equal to the angle between the second bent portion and the second blade; the third blade has a third bent portion and a fourth bent portion sequentially at its end away from the rotating shaft, and the fourth blade has a fifth bent portion at its end away from the rotating shaft; both the third bent portion and the fifth bent portion bend towards the cup base, and the fourth bent portion bends away from the cup base.

[0005] The angle between the first bent portion and the first blade is A, and the angle between the second bent portion and the second blade is B. Therefore, 70°≤A≤80°, 60°≤B≤75°, and A>B. This arrangement ensures that the effective cutting areas of the first and second blades are staggered, facilitating fine cutting and crushing.

[0006] The included angles of the first bends corresponding to the two first blades are not equal. This arrangement causes the effective cutting areas of the two first blades to be staggered, which is beneficial for fine cutting and pulverizing.

[0007] The second blade also has a first arc-shaped portion, a sixth bend, and a second arc-shaped portion. The second bend connects to the first blade sequentially via the first arc-shaped portion, the sixth bend, and the second arc-shaped portion. The angle between the sixth bend and the second blade is C, where 15°≤C≤30°. The arrangement of the first arc-shaped portion, the sixth bend, and the second arc-shaped portion allows the corner of the second blade to be smooth and closer to the cup seat, which is beneficial for cutting and crushing.

[0008] The angle between the third bend and the third blade is D, and the angle between the fourth bend and the third blade is E. Therefore, 40°≤D≤50° and 10°≤E≤30°. This arrangement ensures the cutting and crushing effect.

[0009] The angle between the fifth bend and the fourth blade is F, then 35°≤F≤50°. This setting facilitates fine cutting and crushing.

[0010] The angles between the two fourth blades and their corresponding fifth bends are not equal. This arrangement ensures that the effective cutting areas of the two fourth blades are staggered, which is beneficial for fine cutting and pulverization.

[0011] The length of the first blade is shorter than the length of the second blade; the length of the third blade is longer than the length of the fourth blade. This arrangement ensures that the effective cutting areas of each blade are staggered, facilitating fine cutting and pulverization.

[0012] Two first blades are integrally formed and arranged opposite each other; two second blades are integrally formed and arranged opposite each other; the first blade and the second blade are perpendicular to each other; two third blades are integrally formed and arranged opposite each other; two fourth blades are integrally formed and arranged opposite each other; the third blade and the fourth blade are perpendicular to each other; the first blade is perpendicular to the third blade or the fourth blade. This arrangement facilitates the placement of the item to be cut or shredded.

[0013] The cup holder has several raised ridges on its surface facing the cup body, and these ridges are arranged radially around the pivot point. The raised ridges prevent movement of the object and facilitate cutting.

[0014] By adopting the above scheme, by setting two of each of the first, second, third, and fourth bent blades, the number of times the item is cut and crushed can be guaranteed, which helps to make the item more finely pulverized. Furthermore, by adjusting the angle of the bent part, it can be ensured that items such as ice are crushed thoroughly and evenly, and that ice is less likely to remain. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-7 As shown, this utility model discloses a blender, which includes a cup body 10 and a cup base 20. The cup body 10 is detachably connected to the cup base 20, for example, by screwing or snapping. The cup body 10 and the cup base 20 cooperate to form a blending chamber 11 for holding food or ice that needs to be crushed or pulverized. To facilitate cutting and crushing, a number of protrusions 21 are provided on the surface of the cup base 20 facing the cup body 10. These protrusions 21 are arranged radially around the rotating shaft 35.

[0028] A blade is provided on the cup holder 20 and placed in the mixing chamber 11. The blade includes a rotating shaft 35 and two first blades 31, two second blades 32, two third blades 33 and two fourth blades 34 disposed on the rotating shaft 35. The rotating shaft 35, the first blades 31, the second blades 32, the third blades 33 and the fourth blades 34 rotate synchronously. The cup holder 20 is provided with a drive motor assembly for driving the rotating shaft 35 to rotate. This is a structure that all mixers have and is existing technology. The structure of the drive motor assembly is not the focus of this case and will not be described in detail.

[0029] To facilitate the placement of food, ice, etc., into the blending chamber 11, the blades are designed as follows: Specifically, two first blades 31 are integrally formed and positioned opposite each other; two second blades 32 are integrally formed and positioned opposite each other; two third blades 33 are integrally formed and positioned opposite each other; and two fourth blades 34 are integrally formed and positioned opposite each other. Viewed from above, the first blade 31 and second blade 32 are perpendicular to each other, the third blade 33 and fourth blade 34 are perpendicular to each other, and the first blade 31 and third blade 33 are perpendicular to each other. Alternatively, the first blade 31 and fourth blade 34 are perpendicular to each other. In this case, the first blade 31, second blade 32, third blade 33, and fourth blade 34 are arranged sequentially from the direction closest to the cup body 10.

[0030] To ensure effective cutting and pulverizing, the bending angles and lengths of each blade were designed. Specifically, a first bending portion 36 is provided at the end of the first blade 31 away from the rotating shaft 35. At the end of the second blade 32 away from the rotating shaft 35, a first arc-shaped portion 37, a sixth bending portion 3d, a second arc-shaped portion 38, and a second bending portion 39 are sequentially provided. The first bending portion 36, the sixth bending portion 3d, and the second bending portion 39 all bend away from the cup holder 20. The arches of the first arc-shaped portion 37 and the second arc-shaped portion 38 point towards the cup holder 20. At the end of the third blade 33 away from the rotating shaft 35, a third bending portion 3a and a fourth bending portion 3b are sequentially provided. At the end of the fourth blade 34 away from the rotating shaft 35, a fifth bending portion 3c is provided. The third bending portion 3a and the fifth bending portion 3c both bend towards the cup holder 20, while the fourth bending portion 3b bends away from the cup holder 20 (relative to the third bending portion 3a). The length L1 of the first blade 31 is less than the length L2 of the second blade 32, and the length L3 of the third blade 33 is greater than the length L4 of the fourth blade 34.

[0031] In this design, the angle between the first bent portion 36 and the first blade 31 is A, and the angle between the second bent portion 39 and the second blade 32 is B. Therefore, 70°≤A≤80°, 60°≤B≤75°, and A>B. The angles between the first bent portions 36 corresponding to the two first blades 31 can be unequal, so that the effective cutting areas of the two first blades 31 are staggered, which is beneficial for fine cutting and crushing. The angle between the sixth bent portion 3d and the second blade 32 is C, therefore, 15°≤C≤30°.

[0032] The angle between the third bend 3a and the third blade 33 is D, and the angle between the fourth bend 3b and the third blade 33 is E. Therefore, 40°≤D≤50° and 10°≤E≤30°.

[0033] The angle between the fifth bend 3c and the fourth blade 34 is F, then 35°≤F≤50°. The angles between the two fourth blades 34 and the corresponding fifth bend 3c are not equal, so that the effective cutting areas of the two fourth blades 34 are staggered, which is beneficial for fine cutting and crushing.

[0034] It should be noted that the bent portions mentioned in this case (i.e., the first bent portion 36, the second bent portion 39, the third bent portion 3a, the fourth bent portion 3b, the fifth bent portion 3c, and the sixth bent portion 3d) are all straight or nearly straight.

[0035] The key to this invention lies in the fact that by setting two of each of the bent first blade 31, second blade 32, third blade 33, and fourth blade 34, the number of times the item is cut and pulverized can be guaranteed, resulting in a finer grinding. Furthermore, by designing and adjusting the angle of each bend, it ensures that items such as ice are pulverized thoroughly and evenly, minimizing ice residue. Additionally, the added protrusion 21 prevents item movement, facilitating cutting.

[0036] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
