Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soymilk makers, and in particular to a grinding blade and a soymilk maker. Background Technology
[0002] As people's living standards improve, they are paying more and more attention to healthy eating. Soy milk, as a nutritious beverage, is loved by the public. As a common household appliance for making soy milk, the performance and quality of a soy milk maker directly affect the soy milk's production results and the user experience.
[0003] Currently, the blades of most common soy milk makers have relatively traditional cutting angles and methods. During the blending process, the blades do not completely cut the soybeans. When the soybeans are struck and cut by the blades, some soybeans are simply broken up but not fully crushed, resulting in a large number of incompletely cut soybean particles remaining. This leads to a rough texture and reduced nutritional value in the soy milk. Utility Model Content
[0004] The purpose of this invention is to provide a crushing tool that can effectively cut and crush soybeans.
[0005] Another objective of this invention is to provide a soy milk maker that can fully cut and crush soybeans, thereby improving the quality of the produced soy milk.
[0006] To achieve the above objectives, the solution of this utility model is:
[0007] A crushing tool includes an upper blade, a lower blade, and a rotating shaft;
[0008] The upper blade is positioned above the lower blade, and the upper end of the rotating shaft is connected to the upper blade and the lower blade;
[0009] The upper blade includes an upper root and four upper blades distributed in a cross shape around the upper root. Two of the upper blades are symmetrical and extend horizontally, while the remaining two upper blades are bent upwards. Each upper blade is provided with an upper cutting edge.
[0010] The lower blade includes a lower blade root and four lower blades distributed in a cross shape around the lower blade root. Each lower blade is arc-shaped, with two symmetrical lower blades bent downwards and the remaining two lower blades bent upwards. Each lower blade has a lower cutting edge on its outer arc edge.
[0011] The upper blades of the upper blade and the lower blades of the lower blade are staggered.
[0012] Furthermore, the bending angle of the upward-bending upper blade is between 120° and 135°.
[0013] Furthermore, the upper cutting edge is located on the upper surface of the upper blade and the angle between it and the upper blade body is between 145° and 165°.
[0014] Furthermore, the lower blade is an arc shape with a tapering outer end; the upper blade is a straight line shape with a tapering outer end; and the length of the lower blade is longer than the length of the upper blade.
[0015] Furthermore, the upper and lower blades are distributed at an angle of 45°.
[0016] Furthermore, the outer arc radius of the lower blade is between R30mm and R35mm; the lower edge of the lower cutting edge of the outer arc of the lower blade has several small concave arcs; and the inner arc of the lower blade has several large concave arcs.
[0017] Furthermore, the lower blade has at least 17 small arcs, which are connected sequentially and have the same radius, with each small arc having a radius between R1.85mm and R2.5mm; the lower blade also has at least 4 large arcs, which are connected sequentially and have the same radius, with each large arc having a radius between R3.85mm and R5mm.
[0018] Furthermore, the bending angle of the upward-bending lower blade is between 150° and 160°; the bending angle of the downward-bending lower blade is between 155° and 160°, and the downward-bending lower blade includes a bending body and an end protrusion, with the included angle between the end protrusion and the bending body being between 150° and 156°.
[0019] Furthermore, the upper end of the rotating shaft passes through and connects sequentially to the middle of the lower root of the lower blade and the middle of the upper root of the upper blade.
[0020] This utility model also provides a soymilk maker, including a cup body and the aforementioned grinding blade; the grinding blade is installed from top to bottom at the center of the bottom of the cup body; the inner wall of the cup body is a vertical inner wall; the angle between the upward-bent lower blade of the grinding blade and the vertical inner wall is between 69° and 75°; the inner wall of the cup body is provided with at least three circumferentially spaced turbulence ribs.
[0021] By adopting the above technical solution, the superposition of the upper and lower blades forms upper and lower blades with multiple different shapes and angles, which can increase the contact area with soybeans during crushing, and can more efficiently chop soybeans and other foods, ensuring that soybeans can be thoroughly crushed.
[0022] When this grinding blade is applied to a soymilk maker, the angle between the lower blade and the inner wall of the cup is precisely designed. This angle is a key element in guiding soybeans into the efficient cutting zone, directly affecting the cutting effect and the taste of the soymilk. Simultaneously, the special shape of the lower blade conforms to the shape of the soybeans, increasing the contact area, while the optimized cutting edge angle of the upper blade enhances cutting sharpness. These two elements work together to achieve efficient cutting. The inner wall of the cup also features a flow-dispersing rib structure, which alters the flow trajectory of the liquid and soybeans, effectively and evenly mixing the soybeans and water during stirring, ensuring uniform mixing and thorough cutting of each soybean. This guarantees a better taste and quality of the produced soymilk. Attached Figure Description

Detailed Implementation
[0032] 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. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0033] like Figures 1 to 6 As shown, a crushing tool 10 in this embodiment includes an upper blade 1, a lower blade 2, and a rotating shaft 3.
[0034] The upper blade 1 is positioned above the lower blade 2. The upper end of the rotating shaft 3 is connected to the upper blade 1 and the lower blade 2, and the lower end of the rotating shaft 3 is used to connect to a motor (not shown) installed inside the soymilk maker. The rotating shaft 3 is driven to rotate by the motor, thereby driving the upper blade 1 and the lower blade 2 to rotate and cut and crush soybeans and other foods.
[0035] Specifically, the upper blade 1 includes an upper blade root 11 and four upper blades 12 distributed in a cross shape around the upper blade root 11. Two of the symmetrical upper blades 12 extend horizontally, while the remaining two upper blades 12 are bent upwards. Each upper blade 12 is provided with an upper cutting edge 13.
[0036] The lower blade 2 includes a lower blade root 21 and four lower blades 22 distributed in a cross shape around the lower blade root 21. Each lower blade 22 is arc-shaped, with two symmetrical lower blades 22 bent downwards and the remaining two lower blades 22 bent upwards. Each lower blade 22 has a lower cutting edge 23 on its outer arc edge.
[0037] The upper blades 12 of the upper blade 1 and the lower blades 22 of the lower blade 2 are staggered.
[0038] The superposition of the upper blade 1 and the lower blade 2 forms an upper blade 12 and a lower blade 22 with multiple different shapes and angles, which can increase the contact area with soybeans during crushing, and can more efficiently chop soybeans and other foods, ensuring that soybeans can be thoroughly crushed.
[0039] See Figure 5 In this embodiment, the bending angle A1 of the upward-bending upper blade 12 can be between 120° and 135°, preferably 125°, to increase the cutting area.
[0040] The upper blade 13 is located on the upper surface of the upper blade 12, and the included angle A2 between the upper blade 12 and the body of the upper blade 12 is between 145° and 165°, preferably 158°. The cutting edge angle of the upper blade 13 is set to improve the sharpness of the tool, so as to facilitate the cutting of soybeans.
[0041] See Figure 2The lower blade 22 is an arc shape with a tapering outer end; the upper blade 12 is a straight line with a tapering outer end, and the included angle A3 between the two sides of the upper blade 12 can be 25 degrees; the length of the lower blade 22 is longer than the length of the upper blade 12. By setting the lower blade 22 to an arc shape, it is easier to contact the round soybean, thus increasing the contact area.
[0042] In this embodiment, the upper blade 12 and the lower blade 22 can be distributed at an angle of 45° to facilitate installation and maximize cutting efficiency.
[0043] See also Figure 3 and Figure 4 In this embodiment, the outer arc radius of the lower blade 22 is between R30mm and R35mm, preferably R35mm; the lower edge 23 of the outer arc side of the lower blade 22 has several concave small arcs 221; the inner arc side of the lower blade 22 has several concave large arcs 222. Furthermore, small arcs 221 and large arcs 222 can be respectively provided on the inner and outer arc sides of the arc-shaped lower blade 22, which can increase the contact area with crushed soybean particles of different sizes, thereby improving cutting efficiency.
[0044] Specifically, in this embodiment, the lower blade 22 preferably has at least 17 small arcs 221, which are connected sequentially and have the same radius. The radius of each small arc is between R1.85mm and R2.5mm, preferably R1.85mm. The lower blade 22 preferably has at least 4 large arcs 222, which are connected sequentially and have the same radius. The radius of each large arc is between R3.85mm and R5mm, preferably R3.85mm.
[0045] like Figure 3 and Figure 4 The bending angle A4 of the upward-bending lower blade 22 can be between 150° and 160°, preferably 160°; the bending angle A5 of the downward-bending lower blade 22 is between 155° and 160°, preferably 159.5°, and the downward-bending lower blade 22 includes a bending body 223 and an end protrusion 224, and the included angle A6 between the end protrusion 224 and the bending body 223 is between 150° and 156°, preferably 154.52°.
[0046] Through various bending designs, the cutting area of each lower blade 22 of the lower blade 2 can be effectively increased, thereby increasing the contact area with the soybean during cutting.
[0047] In this embodiment, the upper end of the rotating shaft 3 passes through and connects the middle part of the lower root 21 of the lower blade 22 and the middle part of the upper root 11 of the upper blade 12 in sequence.
[0048] For example Figure 7 and Figure 8This embodiment also provides a soymilk maker 100, including a cup body 20 and the aforementioned grinding blade 10; the grinding blade 10 is installed from top to bottom at the center of the bottom of the cup body 20; the inner wall 4 of the cup body 20 is a vertical inner wall 4; the angle A7 between the downward-bent lower blade 22 of the lower blade 2 of the grinding blade 10 and the vertical inner wall 4 is between 69° and 75°; the inner wall 4 of the cup body 20 is provided with at least three circumferentially spaced turbulence ribs 41.
[0049] Therefore, the angle between the lower blade 22 and the inner wall 4 of the cup body 20 in this soymilk maker 100 is precisely designed. This angle A7 is a core element in guiding soybeans into the efficient cutting area, directly affecting the cutting effect and the taste of the soymilk. At the same time, the special shape design of the lower blade 22 fits the shape of the soybeans, increasing the contact area, and the optimized blade angle of the upper blade 12 enhances the cutting sharpness. The two work together to achieve efficient cutting. The inner wall 4 of the cup body 20 is also equipped with a flow-deflecting rib structure 41, which changes the flow trajectory of the liquid and soybeans, effectively and evenly mixing soybeans and water during stirring, ensuring uniform mixing and allowing each soybean to be fully cut.
[0050] In summary, when the grinding blade 10 of this utility model is applied to the soymilk maker 100, it improves the grinding and stirring efficiency, effectively enhances the taste, quality and nutritional value of soymilk, and brings users a better, more efficient and convenient user experience.
