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] As people's living standards continue to improve, 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, such as meat grinders, include a food container and a mixing blade inside the container; however, the mixing blade can easily cause injury to the hand. 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 mixing blade. The mixing blade includes a mounting portion and a blade extending outward from the mounting portion. The blade includes a back and a cutting edge for cutting food. The cutting edge includes a plurality of sharp blade portions and a plurality of blunt blade portions arranged alternately with the sharp blade portions. The sharp blade portions are recessed towards the back of the blade relative to the blunt blade portions, and extend along curves with different curvatures. Because the sharp blade portions are recessed towards the back of the blade relative to the blunt blade portions, the user will first come into contact with the blunt blade portions before touching the sharp blade portions. In other words, by the sharp blade portions being recessed towards the back of the blade relative to the blunt blade portions, the user's hand is prevented from coming into contact with the sharp blade portions, thereby preventing the sharp blade portions from cutting the user's hand and making it safer to use. During the process of the mixing blade pulverizing food, the blunt blade portions perform primary pulverization, and the sharp blade portions perform secondary pulverization, achieving a good pulverization effect. In addition, because the sharp blade portions extend along curves with different curvatures, the food can fully contact the sharp blade portions during the pulverization process, thereby pulverizing the food more efficiently.

[0005] Furthermore, the width of the blade ranges from 1 mm to 18 mm. This makes it less likely to injure hands and provides a better pulverizing effect on food.

[0006] Furthermore, the blade portion includes a first end near the mounting portion and a second end away from the mounting portion, and the curvature of the blade portion gradually increases from the first end to the second end. When the food processor is working, the ingredients are cut along the blade portion starting from the first end and are cut off at the bottom of the blade portion, resulting in better pulverization efficiency.

[0007] Furthermore, the depth of the blade portion ranges from 0.1 mm to 5 mm. This makes it less likely to injure hands and also provides a better pulverizing effect on food.

[0008] Furthermore, the blade portion includes a first cutting edge recessed towards the back of the blade and a second cutting edge connected to both ends of the first cutting edge, the second cutting edge being protruding relative to the first cutting edge in a direction away from the back of the blade. This allows the blade portion to have a larger size for cutting food, thereby improving the efficiency of food pulverization.

[0009] Furthermore, the blunt edge protrudes from the second cutting edge in a direction opposite to the back of the blade by a height ranging from 0.2 mm to 2.1 mm. This allows the user's hand to more easily contact the blunt edge rather than the sharp edge, preventing hand injury, and also provides a better pulverizing effect on food.

[0010] Furthermore, the thickness of the blunt edge at the end furthest from the back of the blade ranges from 0.05 mm to 1 mm. This reduces the risk of injury to the hand and provides better pulverization of food.

[0011] Furthermore, the width of the blunt blade 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.

[0012] This application provides a stirring blade assembly, which includes a blade shaft and a stirring blade as described above, wherein the stirring blade is disposed on the blade shaft.

[0013] This application provides a food processor, which includes: a food container, including a container body and a container lid covering the container body; a main unit; and a mixing blade assembly as described above, disposed inside the food container, wherein the mixing blade assembly is driven by the main unit.

[0022] The food processor 100 can be a blender, juicer, high-speed blender, stir-fry machine, soy milk maker, meat grinder, etc.

[0023] Please see Figures 1 to 6 The food processor 100 includes a food container 40, a main unit 50, and a blending blade assembly 60. The food container 40 is used to hold food such as meat and vegetables, and includes a container body 41 and a container lid 42 covering the container body 41.

[0024] In the illustrated embodiment, the main unit 50 is disposed on the container lid 42, and the stirring blade assembly 60 is disposed inside the food container 40. The stirring blade assembly 60 is driven by the main unit 50. The stirring blade assembly 60 includes a blade shaft 30 and a stirring blade 35, with the stirring blade 35 disposed on the blade shaft 30. The main unit 50 includes a housing and a motor (not shown) disposed within the housing. The motor shaft is connected to the blade shaft 30 of the stirring blade assembly 60. The stirring blade assembly 60 is used to agitate and pulverize the food in the food container 40.

[0025] Please see Figures 2 to 4 The stirring blade 35 includes a mounting portion 10 and a blade 20 extending outward from the mounting portion 10. The blade 20 includes a back 25 and a cutting edge 21 for cutting food. The cutting edge 21 includes a plurality of sharp blades 216 and a plurality of blunt blades 212 arranged alternately with the sharp blades 216. The sharp blades 216 are recessed toward the back 25 relative to the blunt blades 212, and the sharp blades 216 extend along curves with different curvatures. The stirring blade 35 is mounted to the blade shaft 30 via the mounting portion 10. The number of blunt blades 212 is two or more. The shapes and sizes of the blunt blades 212 can be the same or different.

[0026] Because the sharp blade 216 is recessed towards the back of the blade 25 relative to the blunt blade 212, the user will first come into contact with the blunt blade 212 before touching the sharp blade 216. In other words, by having the sharp blade 216 recessed towards the back of the blade 25 relative to the blunt blade 212, the user's hand is prevented from coming into contact with the sharp blade 216, thus avoiding cuts to the user's hand and making it safer to use. During the process of crushing food with the mixing blade 35, the blunt blade 212 performs primary crushing of the food, while the sharp blade 216 performs secondary crushing, achieving a good crushing effect. In addition, because the sharp blade 216 extends along a curve with different curvatures, the food can fully contact the sharp blade 216 during the crushing process, thereby crushing the food more efficiently.

[0027] Preferably, the width L of the blade portion 216 ranges from 1 mm to 18 mm. This reduces the risk of hand injury and provides better pulverization of food. The "width of the blade portion 216" refers to its dimension along the extension direction of the blade blade 20.

[0028] In some embodiments, the width L of the blade portion 216 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, or any value between any two adjacent values ​​mentioned above.

[0029] The blade portion 216 includes a first end near the mounting portion 10 and a second end away from the mounting portion 10, and the curvature of the blade portion 216 gradually increases from the first end to the second end. When the food processor 100 is working, the ingredients are cut along the blade portion 216 starting from the first end and are cut off at the bottom of the blade portion 216, resulting in better pulverization efficiency.

[0030] Preferably, the depth H1 of the blade portion 216 is between 0.1 mm and 5 mm. This reduces the risk of hand injury and provides better pulverization of food. The "depth of the blade portion 216" refers to the depth of the blade portion along the width direction of the blade blade 20.

[0031] In some embodiments, the depth H1 of the blade portion 216 can be 0.1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or any value between any two of the above.

[0032] Please see Figure 5 and Figure 6 The blade portion 216 includes a first cutting edge 2161 recessed towards the back of the blade 25 and a second cutting edge 2162 connected to both ends of the first cutting edge 2161. The second cutting edge 2162 protrudes relative to the first cutting edge 2161 in a direction away from the back of the blade 25. This allows the blade portion 216 to have a larger size for cutting food, thereby improving the efficiency of food pulverization.

[0033] The height H2 of the blunt blade 212 protruding from the second cutting edge 2162 in a direction away from the back of the blade 25 ranges from 0.2 mm to 2.1 mm. This makes it easier for the user's hand to contact the blunt blade 212 during use, rather than the sharp blade 216, thus avoiding hand injury. It also provides a better pulverizing effect on food.

[0034] In some embodiments, the height H2 of the blunt cutting edge 212 protruding from the second cutting edge 2162 in a direction away from the blade back 25 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 ​​mentioned above.

[0035] The thickness of the blunt blade 212 at the end furthest from the back of the blade 25 ranges from 0.05 mm to 1 mm. This design reduces the risk of hand injury and provides better pulverization of food.

[0036] In some embodiments, the thickness of the blunt edge 212 at the end away from the blade back 25 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.

[0037] The width W of the blunt blade 212 ranges from 0.5 mm to 2.4 mm. This makes it less likely to injure hands and provides better pulverization of food.

[0038] In some embodiments, the width W of the blunt cutting edge 212 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.4 mm, or any value between any two of the above.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
