[0002] At present, the stirring blade structure in cooking machines is generally as shown in a stirring cutter of a food processor with the application number: CN201010562490.6 in a Chinese patent document. It mainly includes a cutter shaft, and upper, middle and lower three-layer blade structures are arranged on the cutter shaft. The adjacent upper, middle and lower blades are staggered, so as to achieve an all-round whipping effect through multiple layers and multiple blades. However, in the production process of the blades of this structure, in order to ensure the strength of the blades, relatively thick metal plates are usually used for integral stamping. The relatively thick metal plates have a high price, which increases the production cost of the blades in terms of raw materials. Moreover, the number of blades that can be stamped from the metal plates of the same area is relatively small for this shape of blades, which is likely to cause waste of the metal plates. And after the blades are stamped and formed, subsequent bending or / and edge-opening processes are also required, and the processes are cumbersome, resulting in a reduction in the production efficiency of the blades and further increasing the production cost. Therefore, the applicant provides a new stirring blade solution through the improvement and perfection of the existing technology for consumers to choose and use. Summary of the Invention

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1:

[0028] As Figure 1 and Figure 2 shown, a louver blade structure for a cooking machine includes a cutter shaft 1, a cutter seat 2 is connected to the cutter shaft 1, a plurality of cutter blades 3 extending outward are connected to the cutter seat 2 along the circumferential direction, a cutting edge 4 is formed on one side of each cutter blade 3, more than one saw blade 5 is further connected to the cutter shaft 1 or the cutter seat 2, at least part of the small saw teeth 6 on the saw blade 5 is located outside the cutter seat 2, a plurality of small saw teeth 6 are formed on the circumferential edge of the saw blade 5, and the number of the small saw teeth 6 is several times more than the number of the cutter blades 3.

[0029] This louver blade structure adds a saw blade 5 with a plurality of small saw teeth 6 on the basis of a conventional cooking knife, so that the louver blade can further improve the crushing effect on food near the cutter seat 2 and make the taste of food more delicate;

[0030] Moreover, the saw blade 5 has a thin thickness, the production raw material cost is low, and the saw blade and the small saw teeth 6 at the edge can be integrally formed by stamping during production. The utilization efficiency of the raw material during stamping is high (compared with the integrally stamped cutter blade, the shape of the saw blade is more regular and the arrangement during stamping is more compact), reducing material waste, and eliminating the process of still needing to edge the cutter blade 3 after stamping. While improving production efficiency, the production cost is greatly reduced, and the structure is simple and the installation is convenient.

[0031] As Figure 3As shown, the saw blade 5 and the tool holder 2 can be connected to the tool shaft 1 by riveting. Specifically, a flat riveting shaft 11 axially extends from the top of the tool shaft 1. Central holes 501 and 201 adapted to be sleeved outside the riveting shaft 11 are respectively formed in the saw blade 5 and the tool holder 2. The stepped surface between the riveting shaft 11 and the tool shaft 1 is used to support the saw blade 5 and the tool holder 2. After the sleeving is completed, the top end of the riveting shaft 11 is riveted, so as to rivet the saw blade 5 and the tool holder 2 on the tool shaft 1.

[0032] Or, as Figure 2 shown, the saw blade 5 can be welded to the top surface and / or the bottom surface of the tool holder, and the tool holder 2 is welded to the top end of the tool shaft 1. When the saw blade 5 is connected below the tool holder 2, the saw blade 5 is provided with a central hole 501 adapted to be sleeved through the tool shaft 1.

[0033] The small saw teeth 6 are continuously and uninterruptedly arranged on the circumferential edge of the saw blade 5, and the shape of the small saw teeth 6 is preferably triangular.

[0034] In this embodiment, two saw blades 5 are provided, one of the saw blades 5 is fixedly connected to the upper side of the tool holder 2, and the other saw blade 5 is fixedly connected to the lower side of the tool holder 2.

[0035] In more embodiments, one or more than two saw blades 5 can be provided. The difference is that one or more than two saw blades 5 are simultaneously fixedly connected to the upper side of the tool holder 2, or are simultaneously fixedly connected to the lower side of the tool holder 2.

[0036] In addition, when more than two saw blades 5 are provided in the louver knife structure, the diameters of each saw blade 5 are the same, or include a large-diameter saw blade 5 and a small-diameter saw blade 5.

[0037] In this embodiment, the saw blade 5 is concentrically connected to the tool shaft 1 or the tool holder 2, so that the saw blade can rotate coaxially, reduce vibration, and can cut the food materials near the tool holder evenly.

[0038] In this embodiment, the saw blade 5 is connected to the tool shaft 1 and is arranged parallel to the tool holder 2.

[0039] In this embodiment, the shape of the saw blade 5 is preferably circular. When the circular saw blade 5 rotates at a high speed, the balance is better, the rotation is stable, and the noise can be reduced.

[0040] In more embodiments, the shape of the saw blade 5 can also be rectangular, or oval, or triangular, or diamond-shaped, or a polygonal structure composed of one or more of the above shapes. Embodiment 2:

[0041] The structure and principle of Embodiment 2 are basically the same as those of Embodiment 1, the difference being that: as Figure 4As shown, the saw blade 5 is eccentrically connected to the cutter shaft 1 or the tool holder 2. In more embodiments, one of the saw blades 5 can be concentrically connected to the cutter shaft 1 or the tool holder 2, and the other saw blade 5 is eccentrically connected to the cutter shaft 1 or the tool holder 2. Embodiment Three:

[0042] The structure and principle of Embodiment Three are basically the same as those of Embodiment One, except that: as Figure 5 shown, the saw blade 5 is connected to the cutter shaft 1 and is inclined relative to the tool holder 2. Embodiment Four:

[0043] In Embodiment Four, as Figure 6 shown, at least two long blade leaves 3a are included among several blade leaves 3, and the two long blade leaves 3a are arranged on opposite sides; and the two long blade leaves 3a extend obliquely upward or / and downward relative to the tool holder 2, and the inclination angle of one long blade leaf 3a is greater than or equal to that of the other long blade leaf 3a; the blade leaf 3 with this structure can improve the whipping efficiency.

[0044] Since the above-mentioned long blade leaves 3a are inclined, when a flat saw blade 5 is simply adhered to the end face of the tool holder 2, a small gap with an included angle will be formed between the long blade leaves 3a and the saw blade 5. After use, food ingredients are likely to get into the small gap and are difficult to clean, resulting in a phenomenon of dirt accumulation, and bacteria are likely to breed after long-term use.

[0045] Therefore, the corresponding solution is: as Figure 7 shown, the saw blade 5 is coaxially and parallelly connected to the cutter shaft 1;

[0046] the saw blade 5 is face-to-face attached to the top surface or / and the bottom surface of the tool holder 2, and a raised portion 502 matching the shape and inclination angle of the long blade leaf 3a is provided at the overlapping part of the saw blade 5 and the long blade leaf 3a, and the raised portion 502 is attached to the blade surface of the long blade leaf 3a; the saw blade 5 is made to match the shape of the long blade leaf 3a, thus avoiding the appearance of small gaps and ensuring the cleanliness and hygiene of the structure of the louver knife. Embodiment Five:

[0047] The difference between Embodiment Five and Embodiment Four is that: as Figure 8 shown, the saw blade 5 is spaced from the tool holder 2, and at the minimum spacing distance, the peripheral edge of the saw blade 5 touches the blade surface of the blade leaf 3; a larger included angle is formed between the saw blade 5 and the long blade leaf 3a, so that even if the gap formed by the included angle gets food ingredients into it, it is easy to clean during the flushing process.

[0048] In Embodiment Four and Embodiment Five, two short blade leaves 3b are further included among several blade leaves 3, and the two short blade leaves 3b extend horizontally outward and are arranged on opposite sides and are arranged in a "cross" with the two long blade leaves 3a. Embodiment Six:

[0049] In the sixth embodiment, as Figure 9 shown, the saw blade 5 can be integrally stamped and formed with the tool holder 2 and a plurality of cutter blades 3. The plurality of cutter blades 3 are evenly distributed along the circumferential direction on the edge of the saw blade 5, and a plurality of small saw teeth 6 are formed on the remaining part of the circumferential edge of the saw blade 5.

[0050] The above is the preferred solution of the present invention, which shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and equivalents.
