Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a knife and a food processor. Background Art

[0002] Existing food processors consist of a main unit, a cup body, a cup lid, and a cutter. The cutter consists of a shaft and a blade, which is typically mounted on the shaft via a blade holder. This type of cutter has gaps between the blade, the holder, and the shaft, making it difficult to clean.

[0003] Therefore, how to design a tool that is easy to clean becomes a problem that needs to be solved urgently. Utility Model Content

[0004] The present application aims to at least solve the technical problem of difficult cleaning of cutting tools existing in the prior art or related art.

[0005] To this end, a first aspect of the present application is to provide a tool.

[0006] A second aspect of the present application is to provide a food processing machine.

[0007] The technical solution of the first aspect of the present application provides a tool, including: a cutter shaft; a plurality of blades, mounted on the cutter shaft and connected to the cutter shaft to form an integrated structure; the parts where the plurality of blades are connected to the cutter shaft are spaced apart from each other along the circumferential direction of the cutter shaft, and the plurality of blades are mounted at at least two positions distributed axially along the cutter shaft.

[0008] The knife provided by the present application includes a knife shaft and multiple blades. The multiple blades are directly mounted on the knife shaft, that is, no blade holder is provided on the knife shaft, thereby simplifying the structure of the knife. At the same time, the blades and the knife shaft are connected as an integrated structure, without forming a gap between the blades and the knife shaft. This prevents food residue from accumulating in the gap during use, making the knife easier to clean.

[0009] Furthermore, the portion where each blade is connected to the cutter shaft is a connecting portion, and the connecting portions of the multiple blades are spaced apart from each other along the circumferential direction of the cutter shaft, and the multiple blades are arranged in at least two layers along the axial direction of the cutter shaft. That is, the blades have multiple installation positions at multiple heights on the cutter shaft, thereby expanding the range of the cutter that can process food. The connecting portions of the multiple blades are spaced apart from each other along the circumferential direction of the cutter shaft, which means that the axial projections of the portions where the multiple blades are connected to the cutter shaft do not overlap, that is, the connecting portions of the multiple blades are completely staggered in the circumferential direction of the cutter shaft, without any overlap. With this structure, when the cutter is processed through a mold, the cutter only needs to be processed by setting two upper and lower molds along the axial direction, thereby simplifying the processing mold of the cutter and reducing the processing cost of the cutter.

[0010] Optionally, the blades are partially embedded in the blade shaft. The blade shaft is an injection molded part. Further, the blades and the blade shaft are injection molded into an integrated structure. Specifically, the blade shaft is injection molded with multiple blades as injection-molded inserts.

[0011] In this setup, the tool itself is an injection-molded part—in other words, an injection-molded tool. During processing, multiple blades can be pre-fabricated and then installed as injection-molded inserts into the mold for the tool shaft. The tool is then injection-molded. This ensures the connection between the shaft and the multiple blades is strong enough.

[0012] Optionally, the materials of the cutter shaft and the blade are different, that is, the cutter shaft is made of a first material, and the blade is made of a second material.

[0013] Optionally, the multiple blades are connected to the same outer side wall of the blade shaft. That is, the multiple blades are arranged on the same arcuate surface, that is, the multiple blades are not arranged on multiple separate side walls. This simplifies the structure of the blade shaft and facilitates injection molding using upper and lower molds.

[0014] Optionally, the blade shaft includes a first shaft section, the first shaft section being cylindrical or truncated cone-shaped, and the plurality of blades being mounted on the first shaft section. That is, the plurality of blades are mounted on the same section of the cylinder or truncated cone, thereby simplifying the structure of the blade shaft and facilitating injection molding using upper and lower molds.

[0015] In the existing solution, a blade holder is provided for each layer of the multi-layer blade, which makes it impossible to install the multi-layer blades on the surface of the same cylinder. In this way, multiple molds need to be set up for processing during injection molding, which makes the processing cost of the tool higher.

[0016] Optionally, the blade shaft includes a first shaft section on which the plurality of blades are mounted. The blade shaft also includes a second shaft section connected to the first shaft section. The first shaft section and the second shaft section are arranged in a stepped manner, with the outer diameter of the first shaft section being larger than the outer diameter of the second shaft section.

[0017] In this technical solution, the blade shaft is divided into two sections. One section, the first section, is used to mount the blade, while the other section, the second section, is used to cooperate with a drive device such as a motor to drive the blade shaft. The first and second sections of the blade shaft are arranged in a stepped manner, with the first section being thicker, to ensure the strength of the blade shaft.

[0018] Optionally, the shaft body of the first shaft section has the same diameter, that is, the first shaft section is a smooth structure without additional bosses, grooves, etc., so as to facilitate ejection of the cutter shaft during injection molding.

[0019] Optionally, the first shaft section and the second shaft section are integrally injection molded, thereby increasing the structural strength of the cutter shaft and preventing the formation of dead angles, thereby facilitating cleaning of the cutter shaft.

[0020] Optionally, the diameter of the first shaft section is greater than 22 mm and less than 27 mm. The diameter of the first shaft section can be set as needed, but it cannot be too thin, otherwise the strength cannot be ensured, nor can it be too thick, otherwise it is difficult to install or drive.

[0021] Optionally, the first shaft segment includes a first end face and a second end face arranged opposite to each other along the axial direction of the cutter shaft. Along the axial direction of the cutter shaft, a first distance H1 is set between the multiple blades and the first end face, and a second distance H2 is set between the multiple blades and the second end face.

[0022] This arrangement can ensure that there is a certain distance between the blade and both end surfaces of the first shaft segment, thereby ensuring the installation strength of the blade.

[0023] The first distance and the second distance can be set according to actual needs, but both are greater than 0 mm.

[0024] Optionally, the tool further includes: a transmission head mounted on the end of the second shaft segment away from the first shaft segment; wherein the transmission head and the cutter shaft are integrally injection molded, or the transmission head and the cutter shaft are detachable structures.

[0025] In this technical solution, the tool also includes a transmission head, which is used to drive the tool's rotation. Of course, in other solutions, contactless drive of the cutter shaft can be achieved through magnetic drive or other methods, in which case the tool does not need a transmission head. The transmission head can be integrally injection molded with the cutter shaft. Furthermore, to enhance the strength and wear resistance of the transmission head, the transmission head and cutter shaft can be machined separately and then mounted on the cutter shaft.

[0026] Optionally, the transmission head and the cutter shaft are made of different materials, which makes the material selection more flexible when the transmission head and the cutter shaft are integrally injection molded. The cutter shaft is injection molded with multiple transmission heads as injection inserts.

[0027] Optionally, the blade comprises a metal blade and / or a ceramic blade. The blade is a stainless steel blade.

[0028] Optionally, the knife shaft includes a plastic shaft, which is cheaper and lighter, and thus more convenient to drive.

[0029] Optionally, the circumference of the portion where the multiple blades are set on the blade shaft is D, the connecting surface between the blade and the outer wall of the blade shaft is an arc surface, the arc length of the arc surface is A, wherein the ratio of A to D is greater than or equal to 1 / 5 and less than or equal to 1 / 4.

[0030] Optionally, the number of blades is at least 4. If the number is too small, the knife cannot ensure the crushing effect of the food, and if the number is too large, it will cause the multiple knives to be difficult to arrange in the circumferential direction of the knife shaft, thereby failing to ensure the strength of the knife.

[0031] Since the multiple blades are not overlapped along the circumference of the blade shaft, the circumference of the blade shaft will affect the number of blades and the circumferential width of the blades. To balance the number and width of blades, the ratio of A to D can be set within the range of 1 / 5-1 / 4. In this way, 4 or 5 blades can be set, thereby ensuring the number of blades and a wide width of the blades, thereby ensuring the strength of the blades.

[0032] Optionally, the spacing between the plurality of blades along the axial direction of the cutter shaft is consistent. The spacing between the plurality of blades along the circumferential direction of the cutter shaft is consistent.

[0033] Optionally, the number of blades is 4.

[0034] Optionally, the directions of the plurality of blades are consistent and the sharpening directions are consistent. Of course, the directions of the blades and the sharpening directions can also be arranged according to actual needs.

[0035] Optionally, the blade includes a curved blade, a strip blade, etc.

[0036] The technical solution of the second aspect of the present application provides a food processing machine, including the cutting tool provided by the technical solution of the first aspect.

[0037] According to the food processor provided in the present application, since it includes the cutting tool provided by the technical solution of the first aspect, the food processor also has all the beneficial effects of the cutting tool provided by any technical solution of the first aspect, which will not be repeated here.

[0038] Furthermore, the food processor includes a main unit, a cup body and a cup cover. The meat grinder is at least partially installed in the cup body for chopping or blending the food in the cup body.

[0039] Additional aspects and advantages of the present application will become apparent in the following description or may be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 4 To describe the knives and food processors provided according to some embodiments of the present application.

[0050] like Figures 1 to 4 As shown, the technical solution of the first aspect of the present application provides a tool, including a tool shaft 1 and multiple blades 2.

[0051] The plurality of blades 2 are mounted on the cutter shaft 1 and connected to the cutter shaft 1 to form an integral structure. The plurality of blades 2 are spaced apart from each other along the circumferential direction of the cutter shaft 1, and the plurality of blades 2 are mounted at at least two positions distributed along the axial direction of the cutter shaft 1. That is, the portions where the plurality of blades 2 are connected to the cutter shaft 1 are arranged in at least two layers along the axial direction of the cutter shaft 1.

[0052] The knife provided herein includes a blade shaft 1 and a plurality of blades 2. The blades 2 are mounted directly on the blade shaft 1, i.e., no blade holder is provided on the blade shaft 1, thereby simplifying the structure of the knife. Furthermore, the blades 2 are integrally connected to the blade shaft 1, eliminating the formation of a gap between the blades 2 and the blade shaft 1. This prevents food residue from accumulating in the gap during use, making the knife easier to clean.

[0053] Further, if Figure 1 and Figure 2As shown, the portion where each blade 2 is connected to the cutter shaft 1 is a connecting portion, and the connecting portions of the plurality of blades 2 are spaced apart from each other along the circumferential direction of the cutter shaft 1. Figure 1 and Figure 4 As shown, multiple blades 2 are arranged in at least two layers along the axial direction of the knife shaft 1. That is, the blades 2 have multiple installation positions at different heights on the knife shaft 1, so that the food processing range of the knife can be expanded. The connecting parts of the multiple blades 2 are spaced apart from each other along the circumferential direction of the knife shaft 1, that is, the projections of the connecting parts of the multiple blades 2 in the axial direction do not overlap, that is, the connecting parts of the multiple blades 2 are completely staggered in the circumferential direction of the knife shaft 1, and there is no overlap. With this structure, when the knife is processed through the mold, the knife only needs to be processed by setting two upper and lower molds along the axial direction, thereby simplifying the processing mold of the knife and reducing the processing cost of the knife.

[0054] Optionally, the blades 2 are partially embedded in the blade shaft. The blade shaft 1 is an injection molded part. Further, the blades 2 and the blade shaft 1 are injection molded into an integrated structure. Specifically, the blade shaft 1 is injection molded with multiple blades 2 as injection molded inserts.

[0055] In this setup, the tool itself is an injection-molded body—in other words, an injection-molded tool. During processing, multiple blades 2 can be pre-fabricated and then installed as injection-molded inserts into the mold for the tool shaft 1. The tool is then injection-molded. This ensures the connection strength between the tool shaft 1 and the multiple blades 2.

[0056] Optionally, the materials of the blade shaft 1 and the blade 2 are different, that is, the blade shaft 1 is made of a first material, and the blade 2 is made of a second material.

[0057] Alternatively, as Figures 1 to 4 As shown, multiple blades 2 are connected to the same outer wall surface of the blade shaft 1. That is, multiple blades 2 are arranged on the same arcuate surface, that is, multiple blades 2 are not arranged on multiple separate sidewall surfaces. This makes the structure of the blade shaft 1 relatively simple, making it easier to perform injection molding using upper and lower molds.

[0058] Alternatively, as Figure 4 As shown, the cutter shaft 1 includes a first shaft section 12, which is cylindrical or truncated cone-shaped, and multiple blades 2 are mounted on the first shaft section 12. That is, multiple blades 2 are mounted on the same section of the cylinder or truncated cone, which makes the structure of the cutter shaft 1 relatively simple, thereby facilitating injection molding through upper and lower molds.

[0059] In the existing solution, a blade holder is provided for each layer of the multi-layer blade 2, so that the multi-layer blade 2 cannot be installed on the surface of the same cylinder. In this way, multiple molds need to be set up for processing during injection molding, which makes the processing cost of the tool higher.

[0060] Alternatively, as Figure 4 As shown, the blade shaft 1 includes a first shaft section 12, on which a plurality of blades 2 are mounted. The blade shaft 1 also includes a second shaft section 14 connected to the first shaft section 12. The first shaft section 12 and the second shaft section 14 are arranged in a stepped manner, with the outer diameter of the first shaft section 12 being larger than the outer diameter of the second shaft section 14.

[0061] In this technical solution, the blade shaft 1 is divided into two sections. One section, namely the first section 12, is used to mount the blade 2, and the other section, namely the second section 14, is used to cooperate with a drive device such as a motor to drive the blade shaft 1. The first section 12 and the second section 14 of the blade shaft 1 are arranged in a stepped manner, and the first section 12 is thicker, so as to ensure the strength of the blade 2 section of the blade shaft 1.

[0062] Alternatively, as Figure 1 and Figure 4 As shown, the shaft body diameter of the first shaft section 12 is consistent, that is, the first shaft section 12 is a smooth structure without additional bosses, grooves, etc. This makes it easier for the cutter shaft 1 to be ejected from the mold during injection molding.

[0063] Optionally, the first shaft section 12 and the second shaft section 14 are integrally injection molded, thereby increasing the structural strength of the blade shaft 1 and preventing the formation of dead angles, thereby facilitating cleaning of the blade shaft 1 .

[0064] Optionally, the diameter of the first shaft section 12 is greater than 22 mm and less than 27 mm. The diameter of the first shaft section 12 can be set as needed, but it cannot be too thin, otherwise the strength cannot be ensured, but it cannot be too thick, otherwise it is difficult to install and drive.

[0065] Alternatively, as Figure 4 As shown, the first shaft segment 12 includes a first end face 122 and a second end face 124 axially opposite to each other. A first distance H1 is set between the plurality of blades 2 and the first end face 122 , and a second distance H2 is set between the plurality of blades 2 and the second end face 124 .

[0066] This arrangement can ensure that there is a certain distance between the blade 2 and both end surfaces of the first shaft section 12, thereby ensuring the installation strength of the blade 2.

[0067] The first distance and the second distance can be set according to actual needs, but both are greater than 0 mm.

[0068] Alternatively, as Figure 4As shown, the tool further includes: a transmission head 3, which is installed at the end of the second shaft section 14 away from the first shaft section 12; wherein the transmission head 3 and the cutter shaft 1 are integrally injection molded, or the transmission head 3 and the cutter shaft 1 are detachable structures.

[0069] In this technical solution, the tool also includes a transmission head 3, which is used to drive the tool's rotation. Of course, in other solutions, contactless drive of the cutter shaft 1 can be achieved through magnetic drive or other methods, in which case the tool does not need a transmission head 3. Instead, the transmission head 3 can be integrally injection molded with the cutter shaft 1. Furthermore, to enhance the strength and wear resistance of the transmission head 3, the transmission head 3 and cutter shaft 1 can be machined separately and then mounted on the cutter shaft 1.

[0070] Optionally, the transmission head 3 and the cutter shaft 1 are made of different materials, which makes the material selection more flexible when the transmission head 3 and the cutter shaft 1 are integrally injection-molded. The cutter shaft 1 is injection-molded with multiple transmission heads 3 as injection inserts.

[0071] Optionally, the blade 2 includes a metal blade and / or a ceramic blade. The blade 2 is a stainless steel blade.

[0072] Optionally, the blade shaft 1 includes a plastic shaft, which is cheaper and lighter, and thus more convenient to drive.

[0073] Alternatively, as Figure 3 As shown, the circumference of the portion where the multiple blades 2 are arranged on the cutter shaft 1 is D, and the connecting surface between the blade 2 and the outer wall of the cutter shaft 1 is an arc surface, and the arc length of the arc surface is A, wherein the ratio of A to D is greater than or equal to 1 / 5 and less than or equal to 1 / 4.

[0074] Since the plurality of blades 2 are not overlapped along the circumference of the cutter shaft 1, the circumference of the cutter shaft 1 affects the number of blades 2 and the circumferential width of the blades. To balance the number and width of the blades 2, the ratio of A to D can be set within a range of 1 / 5-1 / 4. In this way, 4 or 5 blades 2 can be provided, thereby ensuring the number of blades 2 and at the same time ensuring that the blades 2 have a wider width, thereby ensuring the strength of the blades 2.

[0075] Optionally, the number of blades 2 is at least 4. If the number is too small, the effect of the cutter on the food crushing cannot be ensured, and if the number is too large, it will be difficult to arrange the multiple cutters in the circumferential direction of the cutter shaft 1, thereby failing to ensure the strength of the cutter.

[0076] Optionally, the plurality of blades 2 are spaced at the same distance along the axial direction of the cutter shaft 1. The plurality of blades 2 are spaced at the same distance along the circumferential direction of the cutter shaft 1.

[0077] Optionally, the number of blades 2 is four.

[0078] Optionally, the directions of the plurality of blades 2 are consistent and the sharpening directions are consistent. Of course, the directions and sharpening directions of the blades 2 can also be arranged according to actual needs.

[0079] Optionally, the blade 2 includes an arc-shaped blade, a strip-shaped blade, etc.

[0080] The technical solution of the second aspect of the present application provides a food processor (not shown in the figure), including the cutting tool provided by the technical solution of the first aspect.

[0081] According to the food processor provided in the present application, since it includes the cutting tool provided by the technical solution of the first aspect, the food processor also has all the beneficial effects of the cutting tool provided by any technical solution of the first aspect, which will not be repeated here.

[0082] Furthermore, the food processor includes a main unit, a cup body and a cup cover. The meat grinder is at least partially installed in the cup body for chopping or blending the food in the cup body.

[0083] The knife and food processor in this application are further introduced by taking a food processor as an example.

[0084] Existing food processors include a main unit, a cup body, a cup lid, a meat grinder, and a coaster. The meat grinder consists of a detachable upper and lower blades. Users must screw the upper blade onto the lower blade during use, which poses a risk of injury from the blade. A simple and reliable integrated meat grinder structure is now provided, offering greater convenience and safety.

[0085] Specifically, if Figures 1 to 4 As shown, the meat grinder provided in this embodiment is composed of several parts such as a transmission head 3, a plastic shaft body, and a stainless steel blade.

[0086] The upper and lower 4-leaf stainless steel blades of the meat grinder are integrally injection-molded with the plastic shaft, so that there is no gap between the stainless steel blades and the shaft, making it easy to clean.

[0087] In order to optimize the mold opening process of the one-piece injection molding and make the overall structure and mold structure of the meat grinder simpler and more reliable, the following optimization adjustments are made to the meat grinder:

[0088] The axial projections of the connection parts of the blades of each meat grinder and the shaft body do not overlap, so that the meat grinder can be integrally split into upper and lower molds, and the mold structure is simple and reliable.

[0089] At the same time, in order to ensure the reliability of the meat grinder blade after injection molding, the ratio of the arc size at the connection between the blade 2 and the shaft body to the circumference of the shaft body where the blade is located is greater than or equal to 1 / 5 and less than or equal to 1 / 4.

[0090] The shaft of the meat grinder is designed to be divided into two parts, the lower part of the shaft has a diameter ranging from 22mm to 27mm, and the diameter is consistent from top to bottom. According to this structure, the meat grinder is simple in structure and easy to clean.
