Specific Implementation Example 1:

[0038] Please refer to Figures 1 to 5 As shown, this embodiment provides a non-scratching kitchen appliance intermittent blade, including a mounting part 100 and at least one blade body 200 disposed on the mounting part 100. The non-scratching kitchen appliance intermittent blade is used to be installed in a kitchen appliance so that the user can use the kitchen appliance to process food by stirring, crushing and other processes. The kitchen appliance can be a blender, juicer, high-speed blender, stir-fry machine, soy milk maker, meat grinder, etc.

[0039] like Figures 1 to 5 As shown, the blade body 200 includes a cutting edge portion and a plurality of blunt portions 220 extending outward from the cutting edge 201 of the cutting edge portion. The blunt portions 220 are spaced apart from each other, and each side of each blunt portion 220 is blunted.

[0040] In this embodiment, the blunt portion 220 is disposed on the blade body 200 and protrudes from the edge of the blade 201. When the user picks up the spacer blade, the blunt portion 220 will be touched first rather than the blade, thereby preventing the user from being cut by the blade of the blade body and making it safer to use. In addition, the spaced blunt portions 220 can ensure the contact area between the blade of the spacer blade and the food, ensuring the effectiveness of the spacer blade's stirring, crushing and other functions.

[0041] Preferred, such as Figure 5 As shown, in this embodiment, the cutting surface 210 of the blade portion is provided with a recessed portion 230 at the portion corresponding to each of the blunt portions 220.

[0042] In this embodiment, recesses 230 are further provided on the cutting surface 210 at positions corresponding to each blunt portion 220, which can ensure that the blunt portions 220 are not ground when the cutting surface 210 is polished.

[0043] Furthermore, such as Figure 5 As shown, in this embodiment, the two ends of the recessed portion 230 extend to the outer end face of the blunt portion 220 and the inner edge of the cutting surface 210 of the blade portion, respectively.

[0044] Furthermore, such as Figure 5As shown, in this embodiment, the depth of the recess 230 gradually increases from the inner edge of the cutting surface of the blade to the outer end face of the blunt portion 220.

[0045] In this embodiment, the recessed portion 230 extends to the outer end face of the blunt portion 220 and the inner edge of the cutting surface 210 of the blade, respectively. That is, the recessed portion 230 extends from the inner edge of the cutting surface 210 to the outer end face of the blunt portion 220. This ensures that there are no protrusions on the cutting surface 210 that would affect grinding, thus allowing for rotary grinding of the blade body's cutting edge, resulting in higher efficiency. In this embodiment, the recessed portion 230 can be formed by pressing the cutting surface 210 downwards.

[0046] Preferred, such as Figure 4 and Figure 5 As shown, in this embodiment, the cutting surface 210 of the blade portion is inclined, and the inclined side of each blunt portion 220 on the same side as the cutting surface 210 of the blade portion is in contact with the cutting surface 210 of the blade portion. Furthermore, the inclination angle of the inclined side of the blunt portion 220 relative to the back surface of the blade body 200 is equal to the inclination angle of the cutting surface 210 of the blade portion relative to the back surface of the blade body 200.

[0047] As a preferred option, such as Figure 3 As shown, in this embodiment, the distance D1 between the adjacent blunt portions 220 is 5mm to 8mm.

[0048] Furthermore, such as Figure 5 As shown, in this embodiment, the distance D2 between the outer edge of the blunt portion 220 and the edge of the cutting surface 210 is 2mm~3mm.

[0049] In this embodiment, the distance D1 between the blunt portions 220 is controlled between 5mm and 8mm, and the distance D2 between the outer edge of the blunt portion 220 and the edge of the cutting surface 210 is controlled between 2mm and 3mm. This allows the spacer blade to better balance the functions of preventing cuts and processing food such as stirring and chopping.

[0050] Furthermore, in this embodiment, the thickness of the blunt portion 220 can be configured to be greater than or equal to 0.1 mm to further ensure that the blunt portion 220 will not cause harm to the user.

[0051] Preferred, such as Figure 5 As shown, in this embodiment, each of the blunt portions 220 extends inward and connects with the back surface of the blade body 200, so that the back surface of the blade body 200 forms a protrusion 240.

[0052] In this embodiment, the blunt portion 220 also includes a protrusion 240 formed on the back side of the blade body 200, thereby increasing the connection area between the blunt portion 220 and the blade body 200, making the connection between the blunt portion 220 and the blade body 200 more secure, and effectively preventing the blunt portion 220 from falling off the blade body 200. Specific Implementation Example 2:

[0054] The main difference between this embodiment and specific embodiment one is that the specific structure of the blunt portion 220 and its arrangement on the blade body 200 are different in this embodiment. For the remaining structures of this embodiment, please refer to specific embodiment one.

[0055] Please refer to Figures 6 to 10 As shown, this embodiment provides a non-scratching kitchen appliance intermittent blade, including a mounting part 100 and at least one blade body 200 disposed on the mounting part 100. The non-scratching kitchen appliance intermittent blade is used to be installed in a kitchen appliance so that the user can use the kitchen appliance to process food by stirring, crushing and other processes. The kitchen appliance can be a blender, juicer, high-speed blender, stir-fry machine, soy milk maker, meat grinder, etc.

[0056] like Figure 9 and Figure 10 As shown, in this embodiment, the cutting surface 210 of the blade portion is inclined, and the inclined side of each blunt portion 220 on the same side as the cutting surface 210 of the blade portion is in contact with the cutting surface 210 of the blade portion. The inclination angle of the inclined side of the blunt portion 220 relative to the back of the blade body 200 is greater than the inclination angle of the cutting surface 210 of the blade portion relative to the back of the blade body 200, and the inclined side of the blunt portion 220 forms an obtuse angle with the cutting surface 210.

[0057] Preferably, as shown in the figure, in this embodiment, the blade body 200 is provided with a plurality of notches 202 at intervals, the notches 202 are provided along the outer edge of the cutting surface 210, and the blunt portion 220 is provided in the notch 202 and connected to the blade body 200.

[0058] In this embodiment, the blade body 200 has a plurality of notches 202 along the outer edge of the cutting surface 210 for the blunt portion 220 to be provided, and the inclined side of the blunt portion 220 forms an obtuse angle with the cutting surface 210. This ensures that the blunt portion 220 does not protrude from the cutting surface 210 in the vertical direction. When grinding the blade part of the blade body 200, a rotary grinding method can be used, which has higher efficiency.

[0059] As a preferred option, such as Figure 8As shown, in this embodiment, the distance D1 between the adjacent blunt portions 220 is 5mm to 8mm.

[0060] Furthermore, such as Figure 10 As shown, in this embodiment, the distance D2 between the outer edge of the blunt portion 220 and the edge of the cutting surface 210 is 2mm~3mm.

[0061] In this embodiment, the distance D1 between the blunt portions 220 is controlled between 5mm and 8mm, and the distance D2 between the outer edge of the blunt portion 220 and the edge of the cutting surface 210 is controlled between 2mm and 3mm. This allows the spacer blade to better balance the functions of preventing cuts and processing food such as stirring and chopping.

[0062] Furthermore, in this embodiment, the thickness of the blunt portion 220 can be configured to be greater than or equal to 0.1 mm to further ensure that the blunt portion 220 will not cause harm to the user.

[0063] Preferred, such as Figure 10 As shown, in this embodiment, each of the blunt portions 220 extends inward and connects with the back surface of the blade body 200, so that the back surface of the blade body 200 forms a protrusion 240.

[0064] In this embodiment, the blunt portion 220 also includes a protrusion 240 formed on the back side of the blade body 200, thereby increasing the connection area between the blunt portion 220 and the blade body 200, making the connection between the blunt portion 220 and the blade body 200 more secure, and effectively preventing the blunt portion 220 from falling off the blade body 200.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
