DETAILED DESCRIPTION

[0021] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] See Figure 1 and Figure 2 The utility model discloses a mixing knife structure, including a knife shaft 10 and a blade 20. The knife shaft 10 is made of metal. Specifically, the blade 20 includes a blade portion 21 and a connecting portion, and the connecting portion is fixedly connected to the knife shaft 10 by stamping or welding. The blade portion 21 extends from the knife shaft 10 for cutting.

[0025] On the basis of the above structure, when using the mixing knife structure of the present invention, the knife shaft 10 can be connected to the driving motor of a food processor, a meat grinder, a food processor, etc., so that the driving motor drives the rotation of the knife shaft 10. The blade portion 21 of the blade 20 on the knife shaft 10 can process the food in the processing cup during the rotation process.

[0026] It should be noted that since the blade shaft 10 is made of metal, the connection part of the blade 20 can be assembled based on the metal blade shaft 10 and fixed by welding or stamping. This does not require the use of other connecting structures for assembly, thereby reducing the loosening or damage of the blade 20 during later use. The metal blade shaft 10 structure is directly fixed to the connection part of the blade 20, which has better strength.

[0027] In addition, since the blade 20 is fixedly connected to the blade shaft 10, when the mixing blade structure is disassembled, cleaned or replaced, the blade shaft 10 can be directly taken out as a whole, which is convenient for disassembly and cleaning.

[0028] Furthermore, in this embodiment, the connecting portion is a connecting ring 22. When installing the blade 20, the connecting ring 22 of the blade 20 is mounted on the outside of the blade shaft 10 and fixedly connected to the blade shaft 10 by stamping or welding. The connecting ring 22 forms a circle of connecting surface on the outer periphery of the blade shaft 10. In this way, the fixed connecting surface is larger and evenly distributed in the circumferential direction, thereby improving the connection strength and connection stability.

[0029] Furthermore, in order to connect the blade shaft 10 to the drive shaft of the drive motor, a first connector 30 can be provided at one end of the blade shaft 10. The first connector 30 is connected to the end of the blade shaft 10 in a threaded connection manner. The first connector 30 and the drive shaft of the drive motor are plug-fitted or connected by threads or splines 31 to achieve a detachable connection, which is convenient for assembly and disassembly. The first connector 30 is assembled with the blade shaft 10 in a threaded connection manner, which is convenient for assembly and disassembly and can be replaced according to the structure of the drive shaft of the drive motor, and has a wide range of applications.

[0030] Furthermore, a second connector 50 can be provided at the other end of the cutter shaft 10, and the second connector 50 is connected to the end of the cutter shaft 10 in a threaded manner. The second connector 50 can be used to connect to the rotating shaft structure in the processing cup, so that one end of the cutter shaft 10 is connected to the drive shaft through the first connector 30, and the other end of the cutter shaft 10 is connected to the rotating shaft in the processing cup to position the cutter shaft 10, so that the rotation process is stable.

[0031] Furthermore, the blade shaft 10 is provided with a connection channel, the first connector 30 extends into the connection channel and engages with the inner wall thread of the connection channel, and the second connector 50 extends into the connection channel and engages with the inner wall thread of the connection channel. Specifically, the inner walls of both ends of the connection channel are provided with an internal thread structure, and the outer surfaces of the first connector 30 and the outer surfaces of the second connector 50 are provided with an external thread structure. During assembly, the first connector 30 and the second connector 50 can be threadedly connected to the inner thread structure of the connection channel of the blade shaft 10 using the external thread structure, which facilitates assembly and disassembly.

[0032] Furthermore, the first connector 30 and the second connector 50 are both inserted into the connection channel for threaded connection to prevent the thread structure from being exposed. This can effectively reduce the possibility of thread gaps being stuck or water corrosion caused by the entry of materials during the mixing process.

[0033] Furthermore, the first connecting head 30 and the end of the blade shaft 10 are clamped with a first sealing ring 40; the second connecting head 50 and the end of the blade shaft 10 are clamped with a second sealing ring 60, so that after the first connecting head 30 and the blade shaft 10 are connected, the first sealing ring 40 is used to seal the connection position, and similarly, after the second connecting head 50 and the blade shaft 10 are connected, the second sealing ring 60 is used to seal the connection position, which can effectively reduce the situation in which materials enter during the mixing process and the assembly gap is stuck or water corrodes.

[0034] Furthermore, a first step is provided on the exterior of the first connector 30, and the first sealing ring 40 is clamped between the first step and the end of the blade shaft 10; a second step 52 is provided on the exterior of the second connector 50, and the second sealing ring 60 is clamped between the second step 52 and the end of the blade shaft 10. In this way, after the first connector 30 is assembled to the blade shaft 10, the first step can press against the first sealing ring 40, and the first sealing ring 40 is deformed to form a larger sealing surface between the first connector 30 and the blade shaft 10. Similarly, after the second connector 50 is assembled to the blade shaft 10, the second step 52 can press against the second sealing ring 60, and the second sealing ring 60 is deformed to form a larger sealing surface between the second connector 50 and the blade shaft 10.

[0035] Furthermore, an insertion channel 51 is provided in the second connecting head 50, so that the second connecting head 50 and the rotating shaft structure of the processing cup can be plug-fitted and connected. The rotating shaft in the processing cup can be inserted into the insertion channel 51 of the second connecting head 50 to achieve positioning and rotation connection, which is convenient for assembly and disassembly.

[0036] Furthermore, in this embodiment, a spline 31 may be provided at the end of the first connector 30, and a keyway structure matching the spline 31 may be provided on the drive shaft of the drive motor. In this way, assembly is achieved with the spline 31 and the keyway, the assembly and disassembly structure is simple, and the structure is stable after connection.

[0037] Example 2,

[0038] This embodiment also provides a baby food machine, including the stirring knife structure in Example 1. The structure of the baby food machine in this embodiment is the same as that of the prior art. When in use, one end of the blade shaft 10 of the stirring knife structure is connected to the drive shaft of the baby food machine, and the other end of the blade shaft 10 is extended into the processing cup and rotatably connected to the rotating shaft of the processing cup. When in use, the driving motor drives the blade shaft 10 to rotate, which can drive the blade portion 21 of the blade 20 to process food in the processing cup.

[0039] It should be noted that since the blade shaft 10 is made of metal, the connection part of the blade 20 can be assembled based on the metal blade shaft 10 and fixed by welding or stamping. This does not require the use of other connecting structures for assembly, thereby reducing the loosening or damage of the blade 20 during later use. The metal blade shaft 10 structure is directly fixed to the connection part of the blade 20, which has better strength.

[0040] In addition, since the blade 20 is fixedly connected to the blade shaft 10, when the mixing blade structure is disassembled, cleaned or replaced, the blade shaft 10 can be directly taken out as a whole, which is convenient for disassembly and cleaning.

[0041] Of course, the other structures of the stirring blade structure in this embodiment applied to the baby food machine are the same as those in Example 1. Its working principle and effect can be found in Example 1 and will not be described in detail here.

[0042] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
