Description

Technical Field

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

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of food processors can mainly include, but are not limited to, making soy milk, squeezing juice, making rice paste, mincing meat, shaved ice, making coffee and / or preparing facial masks. Food processors can include machines for crushing and mixing food, such as soy milk machines, blenders or wall-breaking food processors. Existing food processors are inconvenient to clean. Utility Model Content

[0003] The present application provides a blending blade assembly and a food processor, which are easier and more thorough to clean.

[0004] On one hand, the present application provides a stirring blade assembly. The stirring blade assembly comprises: a rotating shaft, comprising a driving section, the driving section comprising a plurality of convex edges extending in the up-down direction, and the plurality of convex edges gradually deflecting along the circumference of the driving section; and a blade assembly, detachably mounted on the rotating shaft, the blade assembly comprising a blade holder and a blade fixed to the blade holder, the blade holder comprising a through hole for the rotating shaft to pass through, the blade and / or the blade holder being provided with a flange protruding inwardly from the inner wall of the through hole and a driving hole formed by the flange, the driving hole matching the driving section, and the driving hole comprising a plurality of convex corners extending vertically in the up-down direction; wherein at least some of the plurality of convex edges are respectively provided with protrusions that cooperate with the flange in the upper and lower directions. Since the knife assembly is detachably mounted on the rotating shaft, when the blender cup assembly needs to be cleaned after use, the user rotates the knife assembly along the deflection direction of the convex edge, disassembles the knife assembly, and cleans it thoroughly. In this way, there is no longer any dead corner in the blender cup assembly that cannot be cleaned, effectively avoiding the breeding of bacteria and the generation of odors. At the same time, since the driving section includes a convex edge deflected along the circumferential direction, and the driving hole includes a plurality of convex corners extending vertically along the up and down directions, it can be seen that the convex edge abuts against at least part of the convex corners, and the abutting pressure generated by the convex edge on the convex corners has a downward component force, that is, the convex edge deflected along the circumferential direction has a downward limiting effect on the knife assembly, so that the knife assembly cannot be axially separated from the rotating shaft upward during high-speed rotation. In addition, since at least some of the plurality of convex edges are respectively provided with protrusions that cooperate with the upper and lower limit positions of the flange, when pouring slurry, the protrusions cooperate with the flange limit position, which can prevent the knife assembly from falling off the rotating shaft, and the user experience is better.

[0005] Furthermore, the convex corners include a plurality of adjacent first convex corners and a plurality of adjacent second convex corners, the first convex corners are at a first distance from the center line of the rotating shaft, the second convex corners are at a second distance from the center line of the rotating shaft, and the first distance is greater than the second distance. When the knife assembly is removed from the rotating shaft, the knife assembly is moved horizontally by a certain distance so that the first distance becomes smaller and the second distance becomes larger, and then the knife assembly is removed upwards. At this time, both the first convex corners and the second convex corners can pass through the protrusion smoothly, so that the removal of the knife assembly is more labor-saving.

[0006] Further, the number of the first convex corners is greater than or equal to the number of the second convex corners. In this way, before the knife assembly is removed from the rotating shaft, it can be moved a certain distance in the horizontal direction. The difference between the first distance and the second distance is greater than the height of the protrusion protruding from the convex edge. In this way, by moving the knife assembly in the horizontal direction, the protrusion and the flange can be staggered in the vertical direction, so that the knife assembly can be removed upwards more easily.

[0007] Furthermore, the projection extends in an arc shape in the vertical direction, so that when the knife assembly is removed upward, the flange passes through the projection more smoothly.

[0008] Furthermore, the rotating shaft includes a limiting section arranged at the top, the knife holder includes a limiting wall arranged at the top, and the limiting wall is provided with a limiting hole matching the limiting section. The limiting section cooperates with the limiting hole, so that the rotating shaft can drive the knife assembly to rotate more stably.

[0009] Furthermore, the distance between the top surface of the flange and the highest point of the protrusion is greater than the thickness of the limiting wall. When the knife assembly is removed upward, when the flange reaches the highest point of the protrusion, the limiting wall has been separated from the limiting section, and the knife assembly can be rotated at a certain angle, so that the flange can pass through the protrusion more easily, so that the knife assembly can be disassembled more labor-saving.

[0010] Furthermore, the angle of deflection of the top end of the convex edge relative to the bottom end is between 15 degrees and 75 degrees, and the height of the driving section is between 8 mm and 40 mm. In this way, the convex edge has a good limiting effect on the knife assembly, the knife assembly will not be separated from the rotating shaft during the rotation process or the pulping process, and the installation and removal of the knife assembly is more convenient.

[0011] Furthermore, the blade holder includes a first frame body and a second frame body assembled with the first frame body, and the blade is clamped between the first frame body and the second frame body. In this way, the blade can be assembled to the blade holder more conveniently.

[0012] Furthermore, the deflection direction of the plurality of convex edges from top to bottom is opposite to the rotation direction of the rotating shaft. In this way, the knife assembly is less likely to be separated from the rotating shaft during the rotation process.

[0013] The present application provides a food processor, which includes: a main machine; a mixing cup assembly mounted on the main machine, the mixing cup assembly including a mixing cup and the mixing blade assembly as described above, the mixing blade assembly mounted on the bottom of the mixing cup; and a cup cover assembly, which covers the mixing cup assembly.

[0022] See also Figures 1 to 6 The food processor 100 can be used for making soy milk, rice paste, juice, etc. The food processor 100 includes a main unit 50, a mixing cup assembly 60, and a cup cover assembly 70. The mixing cup assembly 60 is mounted on the main unit 50, and the cup cover assembly 70 is covered on the mixing cup assembly 60. The main unit 50 includes a housing and a motor disposed in the housing. The mixing cup assembly 60 includes a mixing cup 61 and a mixing blade assembly 62, and the mixing blade assembly 62 is mounted on the bottom of the mixing cup 61.

[0023] The stirring blade assembly 62 includes: a rotating shaft 22 and a blade assembly 30. The rotating shaft 22 includes a driving section 220, and the driving section 220 includes a plurality of convex edges 221 extending in the up-down direction, and the plurality of convex edges 221 gradually deflect along the circumference of the driving section 220, and the deflection direction of the plurality of convex edges 221 from top to bottom is opposite to the rotation direction of the rotating shaft 22. The motor shaft of the motor is connected to the rotating shaft 22, and the blade assembly 30 is driven to rotate through the rotating shaft 22 to whip and crush the food in the stirring cup 61.

[0024] The knife assembly 30 is detachably mounted on the rotating shaft 22. The knife assembly 30 includes a knife holder 31 and a blade 32 fixed to the knife holder 31. The knife holder 31 includes a through hole 317 for the rotating shaft 22 to pass through. The blade 32 and / or the knife holder 31 are provided with a flange 329 protruding inwardly from the inner wall of the through hole 317 and a driving hole 320 surrounded by the flange 329. The driving hole 320 matches the driving section 220, and the driving hole 320 includes a plurality of convex corners 321 extending vertically in the up-down direction. Among them, at least some of the plurality of convex edges 221 are respectively provided with protrusions 229 that cooperate with the flange 329 in the up-down direction to limit the position.

[0025] Since the knife assembly 30 is detachably mounted on the rotating shaft 22, when the mixing cup assembly 60 needs to be cleaned after use, the user rotates the knife assembly 30 along the deflection direction of the convex edge 221, removes the knife assembly 30, and cleans it thoroughly. In this way, there is no longer a dead corner in the mixing cup assembly 60 that cannot be cleaned, which effectively avoids the breeding of bacteria and the generation of odors. At the same time, since the driving section 220 includes the convex edge 221 deflected in the circumferential direction, the driving hole 320 includes a plurality of convex corners 321 extending vertically in the up-down direction, and the deflection direction of the plurality of convex edges 221 from top to bottom is opposite to the rotation direction of the knife assembly 30, It can be seen that the convex edge 221 abuts against at least part of the convex corner 321, and the abutting pressure generated by the convex edge 221 on the convex corner 321 has a downward component force, that is, the circumferentially deflected convex edge 221 has a downward limiting effect on the knife assembly 30, so that the knife assembly 30 cannot axially separate from the rotating shaft 22 upward during high-speed rotation; in addition, since at least part of the several convex edges 221 are respectively provided with protrusions 229 that cooperate with the flange 329 in the upper and lower directions, when pouring slurry, the protrusions 229 and the flange 329 are limited and cooperated, which can prevent the knife assembly 30 from falling off the rotating shaft 22, and the user experience is better.

[0026] The convex corners 321 include a first convex corner 3211 and a second convex corner 3212. The first convex corner 3211 has a first distance from the center line of the rotating shaft 22, and the second convex corner 3212 has a second distance from the center line of the rotating shaft 22, and the first distance is greater than the second distance. When the knife assembly 30 is removed from the rotating shaft 22, the knife assembly 30 is moved horizontally by a certain distance so that the first distance becomes smaller and the second distance becomes larger, and then the knife assembly 30 is removed upward. At this time, the first convex corner 3211 and the second convex corner 3212 can both pass through the protrusion 229 smoothly, so that the removal of the knife assembly 30 is more labor-saving.

[0027] The convex corners 321 include a plurality of adjacent first convex corners 3211 and a plurality of adjacent second convex corners 3212, and the number of the first convex corners 3211 is greater than or equal to the number of the second convex corners 3212. In this way, before the knife assembly 30 is removed from the rotating shaft 22, it can move a certain distance in the horizontal direction.

[0028] In the illustrated embodiment, the driving hole 320 is a square, and the convex corners 321 include two adjacent first convex corners 3211 and two adjacent second convex corners 3212. In another embodiment, the driving hole 320 is a pentagon, and the convex corners 321 include three adjacent first convex corners 3211 and two adjacent second convex corners 3212. The above are just some examples, and are not limited to the above examples.

[0029] The difference between the first distance and the second distance is greater than the height of the protrusion 229 protruding from the convex edge 221. Here, the "height of the protrusion 229 protruding from the convex edge 221" refers to the height of the protrusion 229 protruding from the convex edge 221 in the horizontal direction. In this way, by moving the knife assembly 30 in the horizontal direction, the protrusion 229 and the flange 329 can be staggered in the vertical direction, so that the knife assembly 30 can be removed upward with less effort.

[0030] The protrusion 229 extends in an arc shape in the up-down direction. In this way, when the knife assembly 30 is removed upward, the flange 329 passes through the protrusion 229 more smoothly.

[0031] The rotating shaft 22 includes a limiting section 225 disposed at the top, and the knife holder 31 includes a limiting wall 315 disposed at the top, and the limiting wall 315 is provided with a limiting hole 3151 matching the limiting section 225. The limiting section 225 cooperates with the limiting hole 3151, so that the rotating shaft 22 can drive the knife assembly 30 to rotate more stably.

[0032] The distance D between the top surface of the flange 329 and the highest point of the protrusion 229 is greater than the thickness H of the limiting wall 315. When the knife assembly 30 is removed upward, when the flange 329 reaches the highest point of the protrusion 229, the limiting wall 315 has been separated from the limiting section 225. At this time, the knife assembly 30 can be rotated at a certain angle, so that the flange 329 can pass through the protrusion 229 more easily, so that the knife assembly 30 can be disassembled more labor-saving.

[0033] Preferably, the angle of deflection of the top end of the convex edge 221 relative to the bottom end is between 15 degrees and 75 degrees, and the height of the driving section 220 is between 8 mm and 40 mm. In this way, the convex edge 221 has a good limiting effect on the knife assembly 30, the knife assembly 30 will not be separated from the rotating shaft 22 during the rotation process or the pulping process, and the installation and removal of the knife assembly 30 are more convenient.

[0034] In some embodiments, the angle of deflection of the top end of the convex edge 221 relative to the bottom end can be 15 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 75 degrees, or any value between any two of the above. The height H of the driving section 220 can be 8 mm, 12 mm, 16 mm, 20 mm, 24 mm, 28 mm, 32 mm, 36 mm, 40 mm, or any value between any two of the above.

[0035] The blade holder 31 includes a first frame body 311 and a second frame body 312 assembled with the first frame body 311, and the blade 32 is clamped between the first frame body 311 and the second frame body 312. In this way, the blade 32 can be more conveniently assembled to the blade holder 31. In the illustrated embodiment, the first frame body 311 and the second frame body 312 are connected by threads.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
