Description

Technical Field

[0001] This application relates to the field of food processor technology, 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] According to a first aspect of the embodiments of this specification, a stirring blade is provided, comprising a mounting member, a support member extending outward from the mounting member, and a secondary blade member disposed along the length direction of the support member; the support member has a blunt edge; the secondary blade member has a cutting edge, the projection of the secondary blade member in the plane of the support member is located within the support member, and there is a gap between the projection of the cutting edge in the plane of the support member and the blunt edge. Thus, because there is a gap between the projection of the cutting edge in the plane of the mounting member and the blunt edge, the user will first come into contact with the blunt edge before touching the cutting edge. In other words, by creating a gap between the projection of the cutting edge in the plane of the mounting member and the blunt edge, the user's hand is prevented from coming into contact with the cutting edge, thereby preventing the secondary blade member from cutting the user's hand, making it safer to use.

[0005] Furthermore, the blade is equidistant from the blunt edge along its length. This equidistant design maintains the stability of food flow during cutting, preventing stress concentration and breakage of the blade.

[0006] Furthermore, the distance between the projection of the blade onto the plane of the support and the blunt edge is between 0.1 mm and 5 mm. This ensures both effective pulverization of food and prevents the blade from cutting the hand.

[0007] Furthermore, the secondary blade is made of metal and is fixed to the support member by welding or fasteners. This design not only prevents hand cuts but also provides excellent food pulverization and is simple to manufacture.

[0008] Furthermore, the secondary blade includes a blade body and connecting bodies located at both ends of the blade body; the connecting bodies are connected to the support member; the distance between the blade body and the support member is between 1.8mm and 9mm. This allows food to easily slide through the gap between the blade body and the support member, resulting in good pulverizing effect.

[0009] Furthermore, the support member includes a first end and a second end opposite to the first end, and the width of the support member gradually decreases from the first end to the second end. Thus, the wider thickness of the first end increases the contact area between the support member and the cutter shaft, resulting in structural stability, while the narrower width of the second end reduces the contact area with the food, lowering frictional resistance and the possibility of material adhering to the support member, making cutting smoother and chip removal more efficient.

[0010] Furthermore, the distance between the second end and the secondary blade is less than or equal to 3.6 mm. This ensures good food pulverization while preventing hand cuts.

[0011] Furthermore, the first end is provided with a notch that penetrates the blunt edge. Thus, the notch serves to provide a support point for clamping the blade body, facilitating the injection molding of the blade body onto the blade shaft.

[0012] According to a second aspect of the embodiments of this specification, a stirring blade assembly is provided, which includes a blade shaft and the stirring blade described in the first aspect, the stirring blade being disposed on the blade shaft.

[0013] According to a third aspect of the embodiments of this specification, a food processor is provided, comprising:

[0014] A food container, including a container body and a container lid covering the container body;

[0015] Host; and

[0016] The stirring blade assembly as described in the second aspect is disposed inside the food container, and the stirring blade assembly is driven by the host computer.

[0017] This application has the following beneficial effects: Because there is a gap between the projection of the blade on the plane of the mounting part and the blunt edge, the user will contact the blunt edge before touching the blade. In other words, by creating a gap between the projection of the blade on the plane of the mounting part and the blunt edge, the user's hand is prevented from contacting the blade, thereby preventing the secondary blade from cutting the user's hand and making it safer to use.

[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this specification. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described herein with reference to the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If any terms related to directional indication or positional relationship are used in the embodiments of this application, such terms are only used to explain the relative positional relationship and movement of the components in a specific posture; if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, terms such as "first" and "second" used in the embodiments of this application are only used for descriptive convenience and should not be construed as indicating or implying relative importance.

[0027] The embodiments described in this specification will now be described in detail.

[0028] Food processors can be blenders, juicers, high-speed blenders, stir-fry machines, soy milk makers, meat grinders, etc.

[0029] Please refer to Figures 1 to 2 As shown, the food processor includes an ingredient container 200, a main unit 300, and a mixing blade assembly 100.

[0030] The food container 200 is used to hold food such as meat and vegetables. The food container 200 includes a container body 201 and a container lid 202 covering the container body 201. In some embodiments, the container body 201 and the container lid 202 are connected by threads or snaps.

[0031] In the illustrated embodiment, the main unit 300 is disposed on the container lid 202, and the stirring blade assembly 100 is disposed inside the food container 200, and the stirring blade assembly 100 is driven by the main unit 300. The stirring blade assembly 100 includes a stirring blade 101 and a blade shaft 102, with the stirring blade 101 disposed on the blade shaft 102. The main unit 300 includes a housing and a motor disposed within the housing, with the motor shaft connected to the blade shaft 102 of the stirring blade assembly 100. The stirring blade assembly 100 is used to stir and pulverize the food in the food container 200.

[0032] Please continue to refer to the reference. Figure 3-5 As shown, the stirring blade 101 includes a mounting member 10, a support member 20 extending outward from the mounting member 10, and a secondary cutting edge 30 arranged along the length direction of the support member 20. The mounting member 10 is provided with a mounting hole, which is adapted to the inner diameter of the corresponding blade shaft 102, so that the stirring blade 101 is mounted on the blade shaft 102 through the mounting hole.

[0033] In the illustrated embodiment, multiple stirring blades 101 are provided, and the multiple stirring blades 101 are fixed vertically on the blade shaft 102 along its length. Each stirring blade 101 includes two or more support members 20 extending in different directions, and each support member 20 is provided with a secondary blade 30. In this way, the stirring blades 101 can simultaneously act on different height layers and different positions of the material, reducing the occurrence of dead zones in the stirring process.

[0034] The support member 20 has a blunt edge 21, and the secondary cutting edge 30 has a cutting edge 31. The projection of the secondary cutting edge 30 in the plane of the support member 20 is located within the support member 20, and there is a gap between the projection of the cutting edge 31 in the plane of the support member 20 and the blunt edge 21.

[0035] Because there is a gap between the projection of the blade 31 onto the plane of the mounting member 10 and the blunt edge 21, the user will come into contact with the blunt edge 21 before touching the blade 31. In other words, by creating a gap between the projection of the blade 31 onto the plane of the mounting member 10 and the blunt edge 21, the user's hand is prevented from coming into contact with the blade 31, thereby preventing the secondary blade 30 from cutting the user's hand and making it safer to use.

[0036] The number of secondary cutting elements 30 can be one, two, or more, depending on the length of the support element 20. Furthermore, the shape and size of the secondary cutting elements 30 can be the same or different.

[0037] The secondary cutting edge 30 is located on the top of the support member 20. Here, "top" refers to the side closest to the main unit 300. In some cases, the secondary cutting edge 30 may also be located on the bottom of the support member 20. Alternatively, some of the secondary cutting edge 30 may be located on the top of the support member 20, and the other part may be located on the bottom of the support member 20.

[0038] Reference Figures 3-4 As shown, the blade 31 is equidistant from the blunt edge 21 along its length, so that the distance the food travels from the blunt edge 21 to the blade 31 is equal everywhere. This can maintain the stability of the food flow during the cutting process and avoid stress concentration and breakage at a certain point on the blade 31.

[0039] The distance between the projection of the blade 31 onto the plane of the support 20 and the blunt edge 21 is 'a', which ranges from 0.1 mm to 5 mm. This ensures that the blade 31 effectively pulverizes food while preventing cuts. In some embodiments, the distance 'a' between the projection of the blade 31 onto the plane of the support 20 and the blunt edge 21 can be 0.1 mm, 1 mm, 3 mm, 4 mm, 4.5 mm, 5 mm, or any value between any two adjacent values ​​mentioned above.

[0040] The support member 20 and the secondary blade 30 are made of metal, and the secondary blade 30 is fixed to the support member 20 by welding or fasteners. Preferably, the metal material is food-grade stainless steel, but it is not limited to this. In this way, it can prevent hand cuts, has a good pulverizing effect on food, and is simple to manufacture. The fasteners mentioned here can be bolts, pins, etc., and there is no specific limitation.

[0041] Reference Figures 3-5 As shown, the secondary blade 30 includes a blade body 32 and connecting bodies 33 located at both ends of the blade body 32. The connecting bodies 33 are connected to the support member 20, thus the blade body 32, connecting bodies 33, and support member 20 together form a food passage. In this way, after food is cut by the blade 31, it easily slides through the gap between the blade body 32 and the support member 20, resulting in good pulverization. Preferably, the connecting bodies 33 and the support member 20 are integrally formed.

[0042] The distance between the blade body 32 and the support member 20 is c, which ranges from 1.8 mm to 9 mm. In some embodiments, the distance c between the blade body 32 and the support member 20 can be 1.8 mm, 2 mm, 4 mm, 5 mm, 7 mm, 9 mm, or any value between any two adjacent values ​​mentioned above.

[0043] Reference Figures 3-4 As shown, the support member 20 includes a first end 23 and a second end 24 opposite to the first end 23, with the first end 23 fixed to the cutter shaft 102. The width of the support member 20 gradually decreases from the first end 23 to the second end 24. Thus, the greater thickness of the first end 23 increases the contact area between the support member 20 and the cutter shaft 102, resulting in a more stable structure. The smaller width of the second end 24 reduces the contact area with the food, lowering frictional resistance and the possibility of material adhering to the support member 20, making cutting smoother and chip removal more efficient.

[0044] Reference Figures 3-4 As shown, the distance between the second end 24 and the secondary blade 30 is b, where b is less than or equal to 3.6 mm. This ensures good food pulverization while preventing hand cuts. In some embodiments, the distance b between the second end 24 and the secondary blade 30 can be 0.1 mm, 0.8 mm, 1.5 mm, 2 mm, 3 mm, 3.6 mm, or any value between any two adjacent values ​​mentioned above.

[0045] Reference Figure 2 and Figure 4 As shown, the first end 23 is provided with a notch 22 that penetrates the blunt edge 21. When the support member 20 is injection molded on the cutter shaft 102, the notch 22 is used as a support point to clamp the support member 20, thereby ensuring the stability of the connection between the two.

[0046] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all 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.
