Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a mixing blade, a mixing blade assembly, and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors consist of a blending jar and a blade set inside the blending jar; however, existing blending blades pose a problem of easily injuring hands. Utility Model Content

[0003] This application provides a mixing blade, a mixing blade assembly, and a food processor, which reduces the risk of hand injury and makes them safer to use.

[0004] This application provides a stirring blade. The stirring blade includes a mounting portion and a blade extending outward from the mounting portion. The blade includes a first blade body connected to the mounting portion and a second blade body connected to the first blade body. The first blade body includes a first sharp edge and a plurality of first blunt edges. The second blade body includes a second sharp edge and at least one second blunt edge. The first sharp edge includes a first cutting line extending along an arc or a straight line, and the second sharp edge includes a second cutting line extending along another arc or a straight line. The first cutting line and the second cutting line intersect or are parallel. The plurality of first blunt edges are arranged at intervals along the extension direction of the first cutting line, and the first blunt edges protrude beyond the first cutting line in the direction the blade cuts food. At least one second blunt edge is arranged along the extension direction of the second cutting line, and the second blunt edge protrudes beyond the second cutting line in the direction the blade cuts food. Because the first blunt blade protrudes beyond the first cutting line in the direction the blade cuts the food, and the second blunt blade protrudes beyond the second cutting line in the direction the blade cuts the food, the user's hand can be prevented from coming into contact with the first and second sharp blades, thus preventing the first and second sharp blades from cutting the user's hand; during the process of the mixing blade pulverizing the food, the first and second blunt blades perform primary pulverization of the food, while the first and second sharp blades perform secondary pulverization of the food, which can achieve a good pulverization effect.

[0005] Furthermore, the second sharp blade is provided with a second blunt blade portion at its end. Since the second blunt blade portion has a greater thickness than the second sharp blade, it can effectively prevent the tip of the second sharp blade from curling during the process of the mixing blade beating the food.

[0006] Furthermore, the second blade body is bent upwards or downwards relative to the first blade body, and the angle between the second blade body and the first blade body is greater than 0 degrees and less than 180 degrees. In this way, the first and second blade bodies can mix and pulverize ingredients at different heights within the mixing cup, resulting in higher pulverization efficiency.

[0007] Furthermore, the second blade body and the first blade body are on the same plane. This simplifies the manufacturing of the stirring blade.

[0008] Furthermore, the first blade body is tilted upwards or downwards relative to the mounting portion. In this way, the first blade body can pulverize ingredients at different heights within the mixing cup, resulting in higher pulverization efficiency.

[0009] Furthermore, the first sharp blade is divided into several first sharp blade portions by several first blunt blade portions, the width of the first sharp blade portions ranging from 3 mm to 10 mm; and / or, the second sharp blade is divided into at least one second sharp blade portion by at least one second blunt blade portion, the width of the second sharp blade portion ranging from 3 mm to 10 mm. This design reduces the risk of hand injury and provides a better pulverizing effect on food.

[0010] Furthermore, the first blunt blade protrudes from the first cutting line in the direction the blade cuts the food by a length ranging from 0.2 mm to 2.1 mm; and / or, the second blunt blade protrudes from the second cutting line in the direction the blade cuts the food by a length ranging from 0.2 mm to 2.1 mm. This design reduces the risk of hand injury and provides a better pulverizing effect on the food.

[0011] Furthermore, the thickness of the end of the first blunt blade or the end of the second blunt blade ranges from 0.05 mm to 1 mm. This makes it less likely to injure hands and also provides a better pulverizing effect on food.

[0012] Furthermore, the width of the first or second blunt blade portion ranges from 0.5 mm to 2.4 mm. This makes it less likely to injure hands and also provides a better pulverizing effect on food.

[0013] This application also provides a stirring blade assembly. The stirring blade assembly includes a rotating shaft and a stirring blade as described above, the stirring blade being disposed on the rotating shaft.

[0014] Furthermore, the rotating shaft includes an upper bushing and a lower bushing assembled with the upper bushing, and at least one of the stirring blades is clamped between the upper bushing and the lower bushing. Thus, the stirring blade can be conveniently and reliably clamped and fixed by the upper and lower bushings.

[0015] This application also provides a food processor, which includes: a base; and a blending cup assembly assembled on the base, the blending cup assembly including a blending cup and a blending blade assembly, the blending blade assembly being disposed at the bottom of the blending cup.

[0028] The food processor includes a base and a blending jar assembly. The blending jar assembly is assembled into the base and includes a blending jar and a blade assembly, with the blade assembly located at the bottom of the blending jar. The blending jar is used to hold ingredients, and the blade assembly is used to blend and pulverize the ingredients.

[0029] Please see Figures 1 to 5 The stirring blade assembly 50 includes a rotating shaft 30 and stirring blades 40, with the stirring blades 40 disposed on the rotating shaft 30. In the illustrated embodiment, the rotating shaft 30 includes an upper bushing 31 and a lower bushing 32 assembled with the upper bushing 31, with at least one stirring blade 40 clamped between the upper bushing 31 and the lower bushing 32. Thus, the upper bushing 31 and the lower bushing 32 can conveniently and reliably clamp and fix the stirring blade 40. In this embodiment, a gasket 33 is also provided between the lower bushing 32 and the stirring blade 40 to provide a loosening effect. Please refer to [link to previous section]. Figure 6 and Figure 7 The mixing blade assembly may include one, two, or more mixing blades 40.

[0030] The stirring blade 40 includes a mounting portion 10 and a blade 20 extending outward from the mounting portion 10. The blade 20 includes a first blade body 25 connected to the mounting portion 10 and a second blade body 26 connected to the first blade body 25. The first blade body 25 includes a first sharp edge 251 and a plurality of first blunt edges 252. The second blade body 26 includes a second sharp edge 261 and at least one second blunt edge 262. The first sharp edge 251 includes a first cutting line 213 extending along an arc or a straight line, and the second sharp edge 261 includes a second cutting line 213 extending along another arc or a straight line. A cutting line 214 is provided, wherein the first cutting line 213 and the second cutting line 214 intersect or are parallel, and a plurality of first blunt blade portions 252 are arranged at intervals along the extension direction of the first cutting line 213, and the first blunt blade portions 252 protrude from the first cutting line 213 in the direction in which the blade 20 cuts the food, and at least one second blunt blade portion 262 is arranged along the extension direction of the second cutting line 214, and the second blunt blade portion 262 protrudes from the second cutting line 214 in the direction in which the blade 20 cuts the food. A stirring blade 40 may include one blade 20 or multiple blades.

[0031] Since the first blunt blade 252 protrudes beyond the first cutting line 213 in the direction of the blade 20 cutting the food, and the second blunt blade 262 protrudes beyond the second cutting line 214 in the direction of the blade 20 cutting the food, the user's hand can be prevented from coming into contact with the first sharp blade 251 and the second sharp blade 261, thereby preventing the first sharp blade 251 and the second sharp blade 261 from cutting the user's hand; during the process of the mixing blade 40 pulverizing the food, the first blunt blade 252 and the second blunt blade 262 perform primary pulverization of the food, and the first sharp blade 251 and the second sharp blade 261 perform secondary pulverization of the food, which can achieve a good pulverization effect.

[0032] The second sharp blade 261 has a second blunt blade portion 262 at its end. Since the second blunt blade portion 262 has a greater thickness than the second sharp blade 261, it can effectively prevent the end of the second sharp blade 261 from rolling during the process of the stirring blade 40 beating the food.

[0033] Please see Figure 4 The second blade body 26 is bent upwards or downwards relative to the first blade body 25, and the included angle A between the second blade body 26 and the first blade body 25 is greater than 0 degrees and less than 180 degrees. In this way, the first blade body 25 and the second blade body 26 can mix and pulverize ingredients at different heights in the mixing cup, resulting in higher pulverization efficiency.

[0034] The second blade body 26 and the first blade body 25 are on the same plane. This simplifies the manufacture of the stirring blade 40. (See also...) Figure 8The second blade body 26 and the first blade body 25 are on the same plane, and the first cutting line 213 intersects the second cutting line 214. (See also...) Figure 9 The second blade body 26 and the first blade body 25 are on the same plane, and the first cutting line 213 is parallel to the second cutting line 214.

[0035] Please see Figure 5 The first blade body 25 is inclined upwards or downwards relative to the mounting part 10. This allows the first blade body 25 to pulverize ingredients at different heights within the mixing cup, resulting in higher pulverization efficiency. The angle between the first blade body 25 and the mounting part 10 is greater than 0 degrees and less than 90 degrees, and can be set according to specific circumstances.

[0036] The first sharp blade 251 is divided into several first sharp blade portions 2511 by several first blunt blade portions 252, and the width of each first sharp blade portion 2511 ranges from 3 mm to 10 mm. The second sharp blade 261 is divided into at least one second sharp blade portion 2611 by at least one second blunt blade portion 262, and the width of each second sharp blade portion 2611 ranges from 3 mm to 10 mm. This design reduces the risk of hand injury and provides better pulverization of food.

[0037] In some embodiments, the width of the first blade portion 2511 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent values ​​mentioned above. The width of the second blade portion 2611 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent values ​​mentioned above.

[0038] Preferably, the length of the first blunt blade portion 252 protruding from the first cutting line 213 in the direction of cutting the food by the blade 20 is between 0.2 mm and 2.1 mm. The length of the second blunt blade portion 262 protruding from the second cutting line 214 in the direction of cutting the food by the blade 20 is between 0.2 mm and 2.1 mm. This design reduces the risk of hand injury and provides a better pulverizing effect on the food.

[0039] In some embodiments, the length of the first blunt cutting edge 252 protruding beyond the first cutting line 213 in the direction of the blade 20 cutting the food can be 0.2 mm, 0.5 mm, 0.8 mm, 1.1 mm, 1.4 mm, 1.7 mm, 2.1 mm, or any value between any two adjacent values. The length of the second blunt cutting edge 262 protruding beyond the second cutting line 214 in the direction of the blade 20 cutting the food can be 0.2 mm, 0.5 mm, 0.8 mm, 1.1 mm, 1.4 mm, 1.7 mm, 2.1 mm, or any value between any two adjacent values.

[0040] Preferably, the thickness of the end of the first blunt blade portion 252 or the end of the second blunt blade portion 262 is between 0.05 mm and 1 mm. This reduces the risk of injury to hands and provides better pulverization of food.

[0041] In some embodiments, the thickness of the end of the first blunt cutting edge 252 or the end of the second blunt cutting edge 262 can be 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or any value between any two adjacent values ​​mentioned above.

[0042] Preferably, the width of the first blunt blade portion 252 or the second blunt blade portion 262 is between 0.5 mm and 2.4 mm. This reduces the risk of injury to hands and provides better pulverization of food.
