Description

Technical Field

[0001] This application relates to the field of food processors, 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 sharp part and a blunt part, arranged along the thickness direction of the blade, with the blunt part protruding beyond the sharp part in the direction the blade cuts the food. Because the blunt part protrudes beyond the sharp part in the direction the blade cuts the food, the user will come into contact with the blunt part before contacting the sharp part. In other words, by protruding beyond the sharp part, the blunt part can protect the user's hand, preventing contact between the user's hand and the sharp part, thus avoiding cuts and making it safer to use. During the food pulverization process, the blunt part performs primary pulverization, and the sharp part performs secondary pulverization, achieving a good pulverization effect.

[0005] Furthermore, the length of the blunt blade protruding from the sharp blade is between 0.1 mm and 5 mm. This ensures that the user's hand is less likely to come into contact with the sharp blade during use, preventing hand injury, and also provides a better pulverizing effect on food.

[0006] Furthermore, the cutting edge includes a first sharp edge and a second sharp edge, the first sharp edge being opposite to the blunt edge, and the angle between the first sharp edge and the second sharp edge being between 16.9 degrees and 26.6 degrees. This design reduces the likelihood of the cutting edge becoming dull, and also allows for a motor power consumption of less than 300 watts, resulting in lower costs.

[0007] Furthermore, the blunt blade portion includes a first blunt blade surface and a second blunt blade surface, the first blunt blade surface being opposite to the sharp blade portion, and the included angle between the first blunt blade surface and the second blunt blade surface ranging from 16.9 degrees to 26.6 degrees. Thus, on the one hand, the blunt blade portion is less prone to chipping, and on the other hand, the motor power can be less than 300 watts, resulting in low cost.

[0008] Furthermore, the sharp blade portion includes a first sharp edge surface, and the blunt blade portion includes a first blunt edge surface connected to the first sharp edge surface. A V-shaped groove is formed between the first sharp edge surface and the first blunt edge surface, and the connection between the first sharp edge surface and the first blunt edge surface is transitioned by a rounded corner. This makes the blade easy to manufacture and easy to clean after use.

[0009] Furthermore, the thickness of the blade ranges from 1.6 mm to 2.8 mm. This makes the blade easier to manufacture while preventing it from becoming too heavy, thus reducing manufacturing costs.

[0010] Furthermore, the thickness of the blunt blade tip ranges from 0.05 mm to 1 mm. This makes it less likely to injure hands and also provides better pulverization of food.

[0011] Furthermore, the blunt blade extends at a length greater than or equal to the sharp blade. This prevents the user's hand from coming into contact with the tip of the sharp blade, making it safer to use.

[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.

[0021] The food processor 100 can be a blender, juicer, high-speed blender, stir-fry machine, soy milk maker, meat grinder, etc.

[0022] Please see Figure 1 and Figure 2 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.

[0023] 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.

[0024] Please see Figures 3 to 5 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 sharp edge 216 and a blunt edge 212, which are arranged along the thickness direction of the cutting edge 21. The blunt edge 212 protrudes beyond the sharp edge 216 in the direction in which the blade 20 cuts food. The stirring blade 35 is mounted to the blade shaft 30 via the mounting portion 10.

[0025] Because the blunt blade 212 protrudes from the sharp blade 216 in the direction that the blade 20 cuts the food, the user will come into contact with the blunt blade 212 before contacting the sharp blade 216. In other words, by protruding from the sharp blade 216, the blunt blade 212 can protect the user's hand, preventing the user's hand from coming into contact with the sharp blade 216, thereby preventing the sharp blade 216 from cutting the user's hand and making it safer to use. During the process of crushing the food by the mixing blade 35, the blunt blade 212 performs primary crushing of the food, and the sharp blade 216 performs secondary crushing of the food, which can achieve a good crushing effect.

[0026] The length D of the blunt blade 212 protruding from the sharp blade 216 ranges from 0.1 mm to 5 mm. This ensures that, on the one hand, the user's hand is less likely to come into contact with the sharp blade 216 during use, thus avoiding injury, and on the other hand, it provides a better pulverizing effect on food.

[0027] In some embodiments, the length D of the blunt blade portion 212 protruding from the sharp 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.

[0028] The blade portion 216 includes a first sharp edge 214 and a second sharp edge 215. The first sharp edge 214 is opposite to the blunt edge portion 212, and the included angle between the first sharp edge 214 and the second sharp edge 215 is between 16.9 degrees and 26.6 degrees. Thus, on the one hand, the blade portion 216 is less prone to chipping, and on the other hand, the motor power can be less than 300 watts, resulting in low cost.

[0029] In some embodiments, the included angle between the first blade surface 214 and the second blade surface 215 can be 16.9 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 21.8 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26.6 degrees or any value between any two adjacent blade surfaces.

[0030] The blunt cutting edge 212 includes a first blunt cutting surface 2121 and a second blunt cutting surface 2122. The first blunt cutting surface 2121 is opposite to the sharp cutting edge 216, and the included angle between the first blunt cutting surface 2121 and the second blunt cutting surface 2122 is between 16.9 degrees and 26.6 degrees. Thus, on the one hand, the blunt cutting edge 212 is less prone to chipping, and on the other hand, the motor power can be less than 300 watts, resulting in low cost.

[0031] In some embodiments, the included angle between the first blunt cutting edge 2121 and the second blunt cutting edge 2122 can be 16.9 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 21.8 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26.6 degrees or any value between any two adjacent ones mentioned above.

[0032] In the illustrated embodiment, the sharp blade portion 216 includes a first sharp edge surface 214, and the blunt blade portion 212 includes a first blunt edge surface 2121 connected to the first sharp edge surface 214. A V-groove 219 is formed between the first sharp edge surface 214 and the first blunt edge surface 2121, and the connection between the first sharp edge surface 214 and the first blunt edge surface 2121 is transitioned by a rounded corner. This makes the blade 20 easy to manufacture and easy to clean after use.

[0033] Preferably, the thickness of the blade 20 is between 1.6 mm and 2.8 mm. This makes the blade 20 easier to manufacture and avoids it being too heavy, thus reducing manufacturing costs.

[0034] In some embodiments, the thickness of the blade 20 can be 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or any value between any two adjacent values ​​mentioned above.

[0035] Preferably, the thickness of the blunt blade 212 at its end ranges from 0.05 mm to 1 mm. This reduces the risk of injury to the hand and provides a better pulverizing effect on food.

[0036] In some embodiments, the thickness of the end of the blunt cutting edge 212 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 blunt blade portion 212 extends along the length of the blade 20 by a length greater than or equal to the length of the sharp blade portion 216. This prevents the user's hand from coming into contact with the end of the sharp blade portion 216, making it safer to use.

[0038] 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.
