The moving knife assembly comprises a mounting sleeve and a first blade arranged on the mounting sleeve; the installation sleeve is connected with the motor through a rotary reciprocating structure, and the installation sleeve penetrates through the installation shaft. The motor rotates, the mounting sleeve is driven to rotate around the axis of the mounting shaft through the rotary reciprocating structure, and meanwhile, the motor moves along the axial direction of the mounting shaft, so that the moving knife assembly can reciprocate up and down along the axial direction of the mounting shaft while rotating around the axis of the mounting shaft in the food material container.

According to the arrangement, the moving knife assembly rotates around the axis of the mounting shaft in the food material container, and meanwhile, the moving knife assembly reciprocates up and down along the mounting shaft, so that the stirring range is enlarged, and food materials are stirred or cut more uniformly.

In some embodiments, the mounting shaft is coupled to the motor and rotatably coupled to the food material container. The mounting shaft is provided with a second blade located below the moving blade assembly.

As the mounting shaft is provided with the second blade, the mounting shaft is connected with the motor and is rotatably connected with the food material container, so that the second blade is mainly used for cutting food materials when the mounting shaft is rotated under the driving of the motor, and the first blade is mainly used for stirring the food materials, and the stirring and cutting are combined to uniformly stir the food materials.

In some embodiments, the food processor comprises a transmission mechanism comprising a driving gear and a driven gear, the driving gear being connected with the motor; the driven gear is meshed with the driving gear and fixedly connected with the input end of the rotary reciprocating structure.

In some embodiments, the angle of the spiral bevel along the circumferential direction is a,30 degrees.ltoreq.a.ltoreq.150 degrees.

As the angle a is more than or equal to 30 degrees and less than or equal to 150 degrees, the moving knife assembly can be ensured to have enough moving distance, the moving knife assembly is easy to fall back, and finally, the food is stirred more uniformly, for example, if the angle a is too large, the moving knife assembly is not easy to fall back after reaching the highest position, so that the stirring effect is poor; a is too small, the range of rotation is too small, and the range of motion of the moving blade assembly is too small to function as described.

In some embodiments, the distance between the highest position and the lowest position of the spiral bevel is b,5 mm.ltoreq.b.ltoreq.40 mm along the axial direction of the mounting shaft.

Referring to fig. 1, 2 and 4, fig. 1 discloses a first food processor, and fig. 2 and 4 disclose a second food processor. Both of these machines include a blender blade assembly 10, a motor 31, and a food material container 20. Both of the above-mentioned food processors are meat grinders (which may also be used for meat grinder), and thus, further include a container cover 40. In some embodiments, the food processor is not limited thereto, such as a juice extractor, and the like.

Referring to fig. 7, 8, 9 and 10 in combination with fig. 5, the blender blade assembly 10 includes a moving blade assembly 1 and a mounting shaft 21 mounted within a food material container 20. In the embodiment of the present application, the stirring blade assembly 10 includes the active blade assembly 2 (its constitution and the like will be described later), and the active blade assembly 2 includes the mounting shaft 21 and the second blade 22. The mounting shaft 21 is mounted in the food container 20, and the mounting includes two cases: 1) In the case where the mounting shaft 21 needs to be rotated (for example, in the case where the mounting shaft 21 and the second blade 22 form the active blade assembly 2), the mounting shaft 21 is rotatably connected to the food container 20 and is mounted in the food container 20; 2) In the case where the mounting shaft 21 does not need to be rotated, the mounting shaft 21 may be fixedly assembled in the food container 20. The moving blade assembly 1 includes a mounting sleeve 11 and a first blade 12 provided to the mounting sleeve 11. The mounting sleeve 11 is inserted through the mounting shaft 21. The mounting sleeve 11 is connected to the motor 31 by a rotary reciprocating structure 42. The rotary reciprocating structure 42 is used to realize the rotary motion of the moving blade assembly 1 about the mounting shaft 21 and the up-and-down reciprocating motion under the action of the motor 31, and is not limited to the structure shown in the drawings.

Based on the operation of the first rotary reciprocating structure 42 shown in fig. 5, 7, 8, 9, and 10, the second rotary reciprocating structure 42 shown in fig. 11, and the third rotary reciprocating structure 42 shown in fig. 12, it will be understood by those skilled in the art that the rotary reciprocating structure 42 is not limited to the structure shown in the drawings in various embodiments of the present application. Regardless of the rotary reciprocation structure 42, the motor 31 rotates, and the mounting sleeve 11 is driven to rotate about the axis of the mounting shaft 21 by the rotary reciprocation structure 42 while moving in the axial direction of the mounting shaft 21, so that the moving blade assembly 1 reciprocates up and down in the axial direction of the mounting shaft 21 while rotating about the mounting shaft 21 in the food container 20.

In the cooking machine commonly used, stirring sword subassembly includes the axis of rotation and is fixed in the blade of axis of rotation, like this, at cooking machine work in-process, the blade can not change in the epaxial position of axis of rotation, has the inhomogeneous problem of food material stirring. As set forth above, the moving blade assembly 1 rotates around the axis of the mounting shaft 21 in the food container 20, and at the same time, the moving blade assembly 1 reciprocates up and down along the mounting shaft 21, thus increasing the whipping range, and the food is stirred or cut more uniformly, such as the moving blade assembly 1 can avoid the accumulation of the food, so that the food is sufficiently stirred or cut, and thus, the food is stirred or cut more uniformly, including but not limited to, the thickness uniformity, as compared with the case where the position of the blade on the rotating shaft is not changed.

Referring to fig. 7, 8, 9 and 10 in combination with fig. 5, the mounting shaft 21 is connected to the motor 31 and rotatably connected to the food container 20. The mounting shaft 21 is provided with a second blade 22 located below the moving blade assembly 1. Of course, in consideration of only the up-and-down reciprocation of the moving blade assembly 1 along the axial direction of the mounting shaft 21 while rotating about the axis of the mounting shaft 21, the mounting shaft 21 may not be connected to the motor 31, may be fixedly assembled in the food container 20 only in the vertical direction, and the mounting shaft 21 may not be provided with the second blade 22, and in summary, the mounting shaft 21 may mainly function as the mounting sleeve 11 is mounted so that the mounting sleeve 11 can reciprocate up-and-down along the axial direction of the mounting shaft 21 while rotating about the axis of the mounting shaft 21, and the mounting shaft 21 itself may or may not rotate according to the required functions of the food processor as described above.

As set forth above, since the mounting shaft 21 is provided with the second blade 22, the mounting shaft 21 is connected with the motor 31 and rotatably connected with the food container 20, so that the second blade 22 is mainly used for cutting the food under the driving of the motor 31, the first blade 12 is mainly used for stirring the food, and the combination of stirring and cutting makes the food uniformly stirred.

With continued reference to fig. 5, 7, 8, 9 and 10, the blender blade assembly 10 includes a drive mechanism 32 with the motor of the blender blade assembly 10 also coupled to the mounting shaft 21 and the mounting shaft 21 rotatably coupled to the food material container 20. The reduction ratio of the transmission mechanism 32 is 1:1, a speed reducing gear set or a speed increasing gear set; in the case that the transmission mechanism 32 is a reduction gear set or an acceleration gear set, after the installation shaft 21 rotates, the rotation speed of the second blade 22 on the installation shaft 21 is different from the rotation speed of the first blade 12 of the moving blade assembly, so that the food is stirred more uniformly. The transmission mechanism 32 includes a driving gear 321 and a driven gear 322. In the present embodiment, the motor 31, the transmission mechanism 32, the main body housing 33, and the like together constitute the main body 30, and the main body housing 33 includes an upper case 331 and a lower case 332. The upper and lower cases 331 and 332 enclose a cavity that accommodates the motor 31 and the transmission mechanism 32. The drive gear 321 is connected to the motor 31 and the mounting shaft 21. In the case where the mounting shaft 21 does not need to be driven by the motor 31, the driving gear 321 may not be connected to the mounting shaft 21. The driven gear 322 is meshed with the driving gear 321 and is fixedly connected with the input end of the rotary reciprocating structure 42. Of course, the transmission mechanism 32 may also be a belt transmission.

As the transmission mechanism 32 includes the driving gear 321 and the driven gear 322, the motor 31 rotates to rotate the driving gear 321, and the driving gear 321 and the driven gear 322 drive (in some cases, the driving gear 321 drives the mounting shaft 21 to rotate), so as to drive the moving blade assembly 1 to move, and the gear transmission can make the structure of the stirring blade assembly 10 simple, so that the occupied volume is small.

The structure of the rotary reciprocating structure 42 is the same regardless of whether the motor of the stirring blade assembly 10 also drives the mounting shaft 21 to rotate, and the embodiment of the rotary reciprocating structure 42 is described as follows:

Referring to fig. 5, 7, 8, 9 and 10, the food processing machine includes a driving shaft 41, and the driving shaft 41 is connected with the motor 31. Of course, referring to fig. 7, 8, 9 and 10, in the case that the food processor includes the driving mechanism 32, an end of the driving shaft 41 is connected with the driving mechanism 32 as an input end of the rotary reciprocating structure. And the transmission shaft 41 is directly connected to the motor 31 without driving the rotation of the mounting shaft 21 and without including the transmission mechanism 32.

In fig. 5, 6, 7, 8, 9 and 10, the drive shaft 41 includes a helically ascending helical ramp 421. Fig. 6 more clearly illustrates that the spiral bevel 421 spirals up laterally of the drive shaft 41. Fig. 5 illustrates that the mounting sleeve 11 is provided with a mating portion 422. The rotary reciprocation structure 42 includes the drive shaft 41, the spiral bevel 421, and the fitting portion 422. Referring to fig. 8, fig. 8 illustrates that the engaging portion 422 is located at the lowest position of the spiral bevel 421, and the motor 31 rotates and is driven by the driving mechanism 32 (the motor 31 drives the driving gear 321 to rotate, and the driving gear 321 drives the driven gear 322 to rotate, thereby driving the transmission shaft 41 to rotate). The rotation of the transmission shaft 41 causes the spiral bevel 421 and the mating portion 422 to move relatively, that is, because the spiral bevel 421 rotates with the transmission shaft, the spiral bevel 421 is in contact with the mating portion 422, in this process, the spiral bevel 421 is spirally upward, and the mating portion 422 is located on the spiral bevel 421, so that the mounting sleeve 11 can be driven to rotate around the axis of the mounting shaft 21, and the mating portion 422 can be further driven to move spirally upward along the spiral bevel 421 to the highest position, that is, the mounting sleeve 11 rotates around the axis of the mounting shaft 21 and moves upward along the mounting shaft 21 to the highest position of the spiral bevel 421 (the state in the highest position is shown in fig. 9), and as the motor 31 continues to rotate, the spiral bevel 421 is driven to rotate continuously, so that the mating portion 422 is separated from the spiral bevel 421, the mounting sleeve 11 falls from the highest position, and as can be seen by comparing fig. 10 and fig. 9, the spiral bevel 421 is separated from the mating portion 422 and does not contact, and the highest position of the mating portion 422 falls to the lowest position. As shown in fig. 8, in this process, the engaging portion 422 is separated after being contacted with the spiral bevel 421, and the above-described process is repeated to effect the up-and-down reciprocating motion along the axial direction of the mounting shaft 21 while the rotation is being effected.

Referring to fig. 11, in fig. 11, the mounting sleeve 11 is provided with a spiral slope 421, and the spiral slope 421 spirally rises in a lateral direction of the mounting sleeve 11. The drive shaft 41 is provided with the engaging portion 422. Fig. 11 is mainly used to illustrate the movement process of the rotary reciprocating structure 42, and is not used to limit the length of the spiral bevel 421 or the like. The rotary reciprocation structure 42 includes the drive shaft 41, the spiral bevel 421, and the fitting portion 422. In fig. 11, the engaging portion 422 is provided on the drive shaft 41, with the moving blade assembly 1 at the lowest position. Rotation of the drive shaft 41 will drive the mating portion 422 to rotate, such that, during rotation of the mating portion 422, the mating portion 422 will contact the first end 4211 of the spiral bevel 421, and the moving blade assembly 1 is at the lowest position, because the mating portion 422 can only rotate in the same plane, the spiral bevel 421 must move along the R direction, that is, the mounting sleeve 11 rotates around the axis of the mounting shaft 21 while moving upwards, until the second end 4212 of the spiral bevel 421 opposite to the first end 4211 contacts the mating portion 422, and at this time, the moving blade assembly 1 moves to the highest position. As the transmission shaft 41 continues to rotate, the second end 4212 is separated from the fitting portion 422, the moving blade assembly 1 falls down, and the above-described process is repeated, so that the moving blade assembly 1 reciprocates up and down along the axial direction of the mounting shaft 21 while rotating about the axis of the mounting shaft 21.

As set forth above, the spiral bevel 421 cooperates with the mating portion 422 to realize that the moving blade assembly 1 rotates around the axis of the mounting shaft 21 and reciprocates up and down along the axis of the mounting shaft 21, the rotary reciprocating structure is simple, the volume occupied by the stirring blade assembly is small, the moving blade assembly 1 moves smoothly, and the food material stirring is more uniform with a simple structure.

In some embodiments, the spiral bevel 421 has an angle a of 30 degrees.ltoreq.a.ltoreq.150 degrees in the circumferential direction, such as 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 53 degrees, 58 degrees, 60 degrees, 63 degrees, 65 degrees, 68 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, 95 degrees, 98 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, or 150 degrees.

In some embodiments, the distance between the highest position and the lowest position of the spiral bevel 421 along the axial direction of the mounting shaft 21 is b, and b is 5 mm.ltoreq.b.ltoreq.40 mm.

As the arrangement is that b is more than or equal to 5mm and less than or equal to 40mm, the moving knife assembly 1 has enough moving distance, so that food materials are stirred more uniformly.

Referring to fig. 7 to 9, the transmission shaft 41 is provided with the spiral bevel 421, the mounting sleeve 11 is provided with the mating portion 422, the mounting shaft 21 includes a limiting portion 212, and the limiting portion 212 is located below the rotary reciprocating structure 42. When the moving knife assembly 1 is at the lowest position, the mounting sleeve 11 abuts against the limiting portion 212 and the matching portion 422 is at the lowest position of the spiral bevel 421.

By setting the limiting part 212, when the moving blade assembly 1 is at the lowest position, the limiting part 212 abuts against the mounting sleeve 11 and the matching part 422 is at the lowest position of the spiral inclined plane 421, so that the matching reliability of the matching part 422 and the spiral inclined plane 421 is ensured, and further, under the action of the rotary reciprocating structure 42, the moving blade assembly 1 can continuously rotate around the axis of the mounting shaft 21 and reciprocate up and down along the axis of the mounting shaft 21, and finally, the moving blade assembly 1 can smoothly rotate and reciprocate up and down.

Referring to fig. 9 and 7, the stopper 212 is a step around the mounting shaft 21.

As the above arrangement, since the limiting portion 212 is a step around the mounting shaft 21, when the moving blade assembly is located at the lowest position, the whole circumference of the mounting sleeve 11 abuts against the limiting portion 212, so as to ensure that the mating portion is located at the lowest position of the spiral bevel, and further improve the reliability of the mating between the mating portion 422 and the spiral bevel 421.

Referring to fig. 5, 7, 8, 9 and 10, two of the engaging portions 422 are symmetrically disposed, and two of the spiral inclined surfaces 421 are disposed in one-to-one correspondence with the engaging portions 422.

As set forth above, since the engaging portion 422 and the spiral bevel 421 are provided in two and one-to-one correspondence, the moving blade assembly 1 moves more stably.

Referring to fig. 12, another embodiment of the rotational reset structure is as follows: the stirring blade assembly 10 comprises a transmission shaft 41, and the transmission shaft 41 is rotationally connected with the motor 31. In fig. 12, the mounting sleeve 11 is provided with a circle of sliding grooves 423 extending in the circumferential direction, and the drive shaft 41 is provided with an engaging portion 422. In summary, one of the drive shaft 41 and the mounting sleeve 11 may be provided with a circumferential extending ring of sliding grooves 423, and the other may be provided with an engaging portion 422. The rotary reciprocation structure 42 includes the drive shaft 41, the sliding groove 423, and the fitting portion 422. The transmission shaft 41 rotates to enable the sliding groove 423 to move relative to the matching part 422, so that the moving blade assembly 1 rotates around the mounting shaft 21 and reciprocates up and down along the axial direction of the mounting shaft 21.

As mentioned above, the sliding groove 423 cooperates with the matching portion 422 to realize the up-and-down reciprocating motion along the axial direction of the mounting shaft 21 while rotating, the rotary reciprocating structure is simple, the volume occupied by the stirring knife assembly is small, the moving knife assembly 1 moves smoothly, and the food material stirring is more uniform by a simple structure.

Referring to fig. 1 and 2, the food processor shown in fig. 1 is different from the food processor shown in fig. 2 in that: the food processor shown in fig. 2 includes an elastic member 5, and the elastic member 5 functions as described in detail later. The food processor includes a food material container 20, a main machine 30, and any one of the blender blade assemblies 10 described above. In the embodiment of the application, the food processor is exemplified as a meat grinder (of course, dish may be ground or fried), and thus, the food processor further includes a container cover 40. The container cover 40 is covered with the food material container 20, and the food material container 20 is a mixing bowl. When the food processor is not a meat grinder, the food material container 20 has other shapes and can hold food materials so that the food materials can be processed. The mounting shaft 21 is assembled with the food container 20, and of course, when the mounting shaft 21 is connected with the driving gear 321, the mounting shaft 21 is rotatably connected with the food container 20, and when the mounting shaft 21 does not need to be rotated, the mounting shaft 21 may be fixed in the food container 20 and positioned in the vertical direction. The moving blade assembly 1 of the stirring blade assembly 10 reciprocates up and down while rotating in the food material container.

As set forth above, the food processor has at least the beneficial effects of the stirring blade assembly.

The food processor shown in fig. 1 only depends on the gravity of the moving knife assembly 1 (food material compression is included in some cases), and the problem that the moving knife assembly 1 cannot fall or the falling effect is poor due to food material blocking may exist, and in order to improve the problem, referring to fig. 3 and 2, the food processor comprises an elastic piece 5, and the falling of the moving knife assembly 1 is assisted by the elastic piece 5. In one embodiment of the present application, the arrangement of the elastic member 5 is as follows: the food processor further includes a container cover 40 and a main body 30; the container cover 40 is covered with the food material container 20. The main body 30 is assembled to the container cover 40, and includes the motor 31. The two ends of the elastic member 5 are respectively connected with the container cover 40 and the mounting sleeve 11. In other embodiments, the elastic member 5 is connected to the mounting sleeve 11 and the mounting shaft 21 at both ends thereof, respectively.

By the arrangement, the elastic piece is arranged, so that the situation that the moving knife assembly cannot smoothly fall down due to blocking of food materials and the like can be avoided under the auxiliary effect of the elastic piece, and the moving knife assembly is ensured to smoothly fall down. For example, referring to fig. 2 and 3, as the engaging portion 422 moves from the lowest position to the highest position of the spiral inclined surface 421, the elastic member 5 is compressed, and when the engaging portion 422 falls from the highest position, if the food material blocks the moving knife assembly 1 to reset, the elastic member 5 also resets at this time, and further, the moving knife assembly 1 falls under the action of self gravity (in some cases, food material pressing) and the elastic force of the elastic member 5, so that the situation that the moving knife assembly 1 cannot fall smoothly due to the blocking of the food material is avoided. When the elastic member 5 is disposed between the mounting sleeve 11 and the mounting shaft 21, the elastic member 5 acts identically, and it is also possible to avoid the situation that the moving blade assembly 1 cannot smoothly fall down due to the blockage of food materials or the like.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
