Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and specific embodiments so that those skilled in the art may better understand the present invention and practice it, but the examples are not to be construed as limiting the present invention.
As shown in fig. 1 to 11-4, an embodiment of the present invention provides a food processing apparatus including a container body 1, a fixed shaft 5, a blade 45 assembly 4, and a motor 3. The fixed axle 5 is fixed in the bottom of container body 1, and blade 45 subassembly 4 includes pivot 41 and blade 45, and blade 45 sets up in pivot 41, and motor 3 can be dismantled with the upper end of pivot 41 and be connected, and further, the upper portion of pivot is provided with motor connector 44, and motor 3 is connected with pivot 41 through this rotation connector 44. The lower end of the rotating shaft 41 is detachably rotatably connected with the fixed shaft 5, and the fixed shaft 5 supports the rotating shaft 41. Referring to fig. 3 and 4, in a preferred embodiment, the lower end of the rotating shaft 41 is provided with a shaft hole 42, the shaft hole 42 is sleeved on the fixed shaft 5, the shaft hole 42 is a cylindrical hole, and the fixed shaft 5 is a cylinder. Referring to fig. 10-1 to 10-4, the end face of the free end of the fixed shaft 5 is in planar contact with the inner end face of the shaft hole 42; alternatively, the end face edge of the free end of the fixed shaft 5 is in contact with the inner end face of the shaft hole 42, and the end face middle of the free end of the fixed shaft 5 is not in contact with the inner end face of the shaft hole 42. The ratio of the length of the fixed shaft 5 extending into the shaft hole 42 to the width of the gap between the shaft hole 42 and the fixed shaft 5 is 100:1-3. Here, the gap width between the shaft hole 42 and the fixed shaft 5 is the gap width of the rotation shaft 41 and the fixed shaft 5 in the same central axis state, that is, the difference between the radius of the shaft hole 42 and the radius of the fixed shaft 5. Referring to fig. 5 and 6, in another preferred embodiment, the upper end of the fixed shaft 5 is provided with a rotation hole 50, the lower end 40 of the rotation shaft 41 is inserted into the rotation hole 50, the rotation hole 50 is a cylindrical hole, and the lower end 40 of the rotation shaft 41 is a cylinder. Referring to fig. 11-1 to 11-4, the lower end surface of the rotation shaft 41 is in plane contact with the inner end surface of the rotation hole 50; alternatively, the end face edge of the lower end of the rotation shaft 41 is in contact with the inner end face of the rotation hole 50, and the end face middle of the lower end of the rotation shaft 41 is not in contact with the inner end face of the rotation hole 50. The ratio of the length of the lower end 40 of the rotating shaft 41 extending into the rotating shaft to the gap width between the rotating hole 50 and the lower end 40 of the rotating shaft 41 is 100:1-3. The gap width between the rotation hole 50 and the rotation shaft 41 is the gap width in the state where the rotation hole 50 is the same as the rotation shaft 41, that is, the difference between the radius of the rotation hole 50 and the radius of the lower end 40 of the rotation shaft 41. When the rotation of the rotation shaft 41 suddenly stops, the force between the fixed shaft 5 and the rotation shaft 41 can enable the rotation shaft 41 to stop rotating rapidly, and the shaking of the rotation shaft 41 is not too serious.
Referring to fig. 4, in a preferred embodiment, the gap width between the shaft hole 42 and the fixed shaft 5 is 0.15-0.3mm, and further, the gap width between the shaft hole 42 and the fixed shaft 5 is 0.15-0.25mm. If the difference between the diameter of the shaft hole 42 and the diameter of the rotating shaft 41 is too small, the tilting angle of the rotating shaft 41 is too small, the force for counteracting is too small, the rotating shaft 41 needs to swing for many times to stop, and the time is long, so that the safety regulation is not met; if the diameter of the shaft hole 42 is too large as compared with the diameter of the rotating shaft 41, the swing amplitude of the rotating shaft 41 is too large when the rotating shaft 41 is braked, and the generated noise is too large. The depth of the shaft hole 42 is 10-14mm, and further, the depth of the shaft hole 42 is 11-13mm. And the height of the fixed shaft is greater than the depth of the shaft hole. Likewise, if the depth of the shaft hole 42 is too small, the stability of the rotation shaft 41 is poor, and the rotation shaft 41 is easily separated from the fixed shaft 5; if the depth of the shaft hole 42 is too large, the swing amplitude of the rotating shaft 41 is too small after the power device is removed, and the rotating shaft 41 is stopped for too long. When the rotation of the rotation shaft 41 suddenly stops, the force between the fixed shaft 5 and the rotation shaft 41 can enable the rotation shaft 41 to stop rotating rapidly, and the shaking of the rotation shaft 41 is not too serious. Of course, the gap width between the shaft hole 42 and the fixed shaft 5 and the depth value of the shaft hole 42 may be scaled up or down in equal proportion. During the high-speed rotation of the shaft 41, the motor 3 is suddenly removed, and the upper end of the shaft 41 cannot be fixed as a free end. Since the shaft hole 42 is larger than the diameter of the rotating shaft 41, after the upper end of the rotating shaft 41 becomes a free end, the blade 45 assembly 4 is inclined in one direction by centrifugal force and gravity, the edge of the lower end surface of the rotating shaft 41 contacts with the upper part of the fixed column to generate acting force, and the rotating shaft 41 contacts with the lower part of the fixed column to generate acting force. These two forces cancel each other out with the force generated by the rotation of the rotating shaft 41 due to inertia, and the two forces cancel each other out instantaneously, so that the rotating shaft 41 swings in opposite directions while bouncing up, and the opposite forces cancel each other out with the force generated by the rotation of the rotating shaft 41 due to inertia. Because the rotation speed of the rotating shaft 41 is high, the two forces can be counteracted instantly, so that the rotating shaft 41 stops rotating within 1.5s or even 0.5 s.
Referring to fig. 6, in another preferred embodiment, the gap width between the rotation hole 50 and the lower end 40 of the rotation shaft 41 is 0.15-0.3mm, and further, the gap width between the rotation hole 50 and the lower end 40 of the rotation shaft 41 is 0.15-0.25mm. The depth of the rotation hole 50 is 10-14mm, and further, the depth of the rotation hole 50 is 11-13mm. And the lower end 40 of the rotation shaft 41 has a height greater than the depth of the rotation hole 50. The principle is the same as the interaction of the shaft hole and the fixed shaft.
In a preferred embodiment, the surface of the fixed shaft 5 contacting the rotating shaft 41 is a plane, or the edge of the surface of the fixed shaft 5 contacting the rotating shaft 41 is a plane, and the inside of the edge is a recess. The surface of the rotating shaft 41 contacting the fixed shaft 5 is a plane, or the edge of the surface of the rotating shaft 41 contacting the fixed shaft 5 is a plane, and the inside of the edge is concavely arranged. Enabling planar contact between the fixed shaft 5 and the rotating shaft 41. When the motor 3 is removed and the rotating shaft 41 is inclined, the contact point of the rotating shaft 41 and the fixed shaft 5 is at a certain distance from the central axis of the rotating shaft 41, so that the acting force generated by the rotating shaft 41 and the fixed shaft is large enough to quickly offset the force generated by the rotation of the blade 45 assembly 4 due to inertia.
Referring to fig. 7-9, in the preferred embodiment, the center of gravity of the blade assembly 4 is less than 50% of the length of the shaft 41 from the lower end surface of the shaft 41, and the lower center of gravity prevents the shaft 41 from being disengaged from the fixed shaft 5 when the motor 3 is removed. Preferably, the distance from the center of gravity of the blade assembly 4 to the lower end surface of the rotating shaft 41 is 20% -40% of the length of the rotating shaft 41, so that the cutting and placing of the blade 45 are ensured, and meanwhile, when the motor 3 is removed, the rotating shaft 41 is prevented from being separated from the fixed shaft 5, and the blade assembly 4 flies out of the container body 1.

The lowest blade 45 can be fixed on the position of the rotating shaft 41, so that the fixing of other blades 45 is facilitated, the gravity centers of all the blades 45 are ensured not to exceed the height of the midpoint of the rotating shaft 41, and the gravity center of the whole blade assembly 4 is effectively lowered.
Referring to fig. 7, in the preferred embodiment, the blade assembly 4 includes a first blade set and a second blade set disposed at intervals along the length of the shaft 41, each of the first blade set and the second blade set being provided with a plurality of blades 45, further, two adjacent blades are one blade set, two blades below the machine are the first blade set, and the two blades above are the second blade set. The blades 45 of the first and second blade sets are each at an angle of 0-10 ° to the plane of contact of the rotating shaft 41 and the stationary shaft 5. The distance from the height center of the blade 45 of the first blade group to the lower end surface of the rotating shaft 41 is 5% -15% of the length of the rotating shaft 41, and the height center of the blade 45 of the first blade group is the center of the connection points of the plurality of blades 45 of the first blade group and the rotating shaft 41. The blade 45 is convenient for cutting food, and the gravity center of the blade 45 is limited not to be raised, so that the braking speed of the whole blade assembly 4 is influenced. The distance from the height center of the blades 45 of the second blade set to the lower end surface of the rotating shaft 41 is 20% -50% of the length of the rotating shaft 41, and the height center of the blades of the second blade set is the center of the connection points of the plurality of blades 45 of the second blade set and the rotating shaft 41. The blade 45 does not make the center of gravity of the entire blade assembly 4 50% of the length of the high pressure spool 41.
