[0056] and a secondary lock assembly 4 connected to the secondary output shaft 22 and capable of rotating under the drive of the secondary output shaft 22;

[0057] The main locking assembly 3 comprises

[0058] The main lock buckle 31 has a rotating shaft column 311 in the middle thereof, and a main positioning groove is formed at the lower part of the rotating shaft column 311. The main output shaft 21 can be inserted into the main positioning groove and cooperate with the main positioning groove to drive the main lock buckle 31 to rotate; the main lock buckle 31 is also provided with a main lock buckle limiting column 313;

[0059] The main lock seat 32 is fixedly connected to the main lock 31 , and a main through hole 321 is provided in the middle of the main lock seat 32 for allowing the shaft column 311 to pass through.

[0060] The secondary lock assembly 4 comprises

[0061] A secondary lock buckle 41, a connecting hole 411 is provided in the middle of the secondary lock buckle 41, and a secondary lock buckle limiting column 412 is also provided on the secondary lock buckle 41;

[0062] A secondary lock seat 42 is fixedly connected to the secondary lock seat 41, and a secondary through hole 421 is provided in the middle of the secondary lock seat 42 corresponding to the connecting hole 411;

[0063] Auxiliary lock buckle shaft 43, the auxiliary lock buckle shaft 43 is inserted into the connecting hole 411 of the auxiliary lock buckle 41 and the auxiliary through hole 421 of the auxiliary lock buckle seat 42; and the auxiliary lock buckle shaft 43 has an auxiliary positioning groove 431 at the lower part, the auxiliary output shaft 22 can be inserted into the auxiliary positioning groove 431, and cooperate with the auxiliary positioning groove 431 to drive the auxiliary lock buckle 41 and the auxiliary lock buckle seat 42 to rotate; the auxiliary lock buckle shaft 43 is provided with a limiting rib 432 protruding outward, and the auxiliary lock buckle 41 is provided with a secondary stopper 413 that cooperates with the limiting rib 432.

[0064] In addition, the lock assembly in this embodiment further includes a fixing seat 5 fixedly connected to the speed reduction mechanism 2, and the fixing seat corresponding to the main output shaft 21 and the auxiliary output shaft 22 is respectively provided with through holes for the main output shaft 21 and the auxiliary output shaft 22 to pass through, and the main lock assembly 3 and the auxiliary lock assembly 4 are both arranged on the fixing seat 5. The fixing seat 5 corresponding to the main lock assembly 3 and the auxiliary lock assembly 4 is respectively provided with a main lock accommodating cavity 51 and an auxiliary lock accommodating cavity 52 for accommodating the main lock assembly 3 and the auxiliary lock assembly 4. An initial position micro switch 6 is provided on the fixed seat 5 on one side of the main lock buckle accommodating cavity 51, and a locking position micro switch 7 is provided on the fixed seat 5 on the other side of the main lock buckle accommodating cavity 51. When the main lock buckle assembly 3 is in the initial position, the main lock buckle limit column 313 is opposite to the initial position micro switch 6 and triggers the initial position micro switch 6; when the main lock buckle assembly 3 rotates by a preset angle under the drive of the main output shaft 21 and reaches the locking position, the main lock buckle limit column 313 is opposite to the locking position micro switch 7 and triggers the locking position micro switch 7. The main lock buckle accommodating chamber 51 is provided with a semicircular limit groove 511 for limiting the rotation stroke of the main lock buckle assembly 3. When the main lock buckle assembly 3 rotates driven by the main output shaft 21, the main lock buckle limit column 313 moves in the limit groove 511; the initial position microswitch 6 and the locking position microswitch 7 are just opposite to the head and tail positions of the limit groove 511; the auxiliary lock buckle accommodating chamber 52 is provided with an initial position limit wall 521 and a locking position limit wall 522. In the initial position, the auxiliary lock buckle limit column 412 is against the initial position limit wall 521. When the auxiliary lock buckle assembly 4 rotates by a preset angle under the drive of the auxiliary output shaft 22 and reaches the locking position, the auxiliary lock buckle limit column 412 is against the locking position limit wall 522.

[0065] The fixing seat 5 is provided with a fixing cover 8 which can cover the main locking assembly 3 and the auxiliary locking assembly 4 , and the fixing cover 8 is fixedly connected to the fixing seat 5 .

[0066] In this embodiment, the main lock buckle 31 and the auxiliary lock buckle 41 are both roughly semi-circular or disc-shaped with one side being a straight edge and the other side being a major arc edge. The main lock buckle 31 has a main guide surface 314 for easily pressing down the cup cover in the locking direction, and the auxiliary lock buckle 41 has an auxiliary guide surface 414 for easily pressing down the cup cover in the locking direction.

[0067] A main water channel 9 is provided on the deceleration mechanism below the main locking assembly 3 , and a secondary water channel 10 is provided on the deceleration mechanism below the secondary locking assembly 4 .

[0068] When the main lock buckle 31 and the auxiliary lock buckle 41 have not started to lock the cup cover, the main lock buckle limit column 313 and the auxiliary lock buckle limit column 412 are both at their respective initial position limits on the fixed seat, and the main lock buckle limit column 313 also triggers the initial position micro switch 6, so that the control panel of the food processor can identify its working status; at this time, the discs of the main lock buckle 31 and the auxiliary lock buckle 41 have not been rotated out.

[0069] When the cup cover needs to be locked, the main lock assembly 3 and the auxiliary lock assembly 4 rotate 180° in the same speed in the opposite direction, limit the upper part of the cup cover, and at the same time, the sides of the main lock assembly 3 and the auxiliary lock assembly 4 are against the side of the cup cover to achieve the side limit of the cup cover. At this time, the main lock limit column 313 is limited by the inner wall of the locking position of the limit groove 511 on the fixed seat, generating a large stall current for the control board of the food processor to identify, and at the same time, the main lock limit column 313 also triggers the lock position micro switch for the control board of the food processor to identify. When the control board of the food processor simultaneously identifies the stall current and the lock position micro switch signal, it is determined that the main lock assembly 3 and the auxiliary lock assembly 4 have locked the cup cover, and the control board of the food processor outputs a control signal to the speed reduction mechanism assembly 2 to stop it. If only the stall current is identified without the lock position micro switch signal, the control board of the food processor determines that an abnormal stall occurs. At this time, the control board of the food processor drives the speed reduction mechanism assembly to return the main lock assembly 3 and the auxiliary lock assembly 4 to the initial position and alarm.

[0070] When the cup lid is unlocked, the speed reduction mechanism assembly 2 drives the main lock assembly 3 and the auxiliary lock assembly 4 to rotate 180° in the same speed and opposite direction and return to the initial position. When the main lock limit column 313 touches the initial position micro switch, it is recognized by the control board of the food processor, causing the control board of the food processor to output a control signal to the speed reduction mechanism assembly 2 to stop working.

[0071] Considering the matching clearance between the gear transmission components, when returning to the initial position, the rotation angle of the main output shaft will lag behind the auxiliary output shaft by a certain angle, about 5°, causing the auxiliary lock limit column 412 to reach the initial position limit wall 521 first. This will cause a phenomenon: when the auxiliary lock component returns to the initial position, it matches the overall appearance surface smoothly, while the main lock component matches the overall appearance surface with a gap; therefore, in order to solve this problem, the present invention adds a torsion spring 44 inside the auxiliary lock component to make it match the auxiliary lock shaft 43 and the right auxiliary lock 41. When the locking movement is performed, the torsion spring 44 does not work; the two limiting ribs 432 on the auxiliary lock shaft 43 hit the two auxiliary stoppers 413 on the auxiliary lock 41, pushing the entire auxiliary lock component to rotate, see Fig.14 As shown; when unlocking and returning to the initial position, the secondary lock shaft 43 indirectly drives the right secondary lock 41 to rotate through the torsion spring 44, see Fig.15When the secondary lock stopper limit column 412 is limited at the initial position limit wall 521 of the fixing seat, the secondary lock 41 is restricted from continuing to rotate, and at this time the secondary lock shaft 43 can continue to rotate a certain angle α until the primary lock stopper limit column 313 is limited at the initial position limit of the limit groove 511, see Fig.16 At this time, the rotation angle errors of the main lock component 3 and the auxiliary lock component 4 are offset, and the main and auxiliary locks can be flush with the appearance of the entire machine.

[0072] In addition, the present invention further provides a food processor, comprising a cup body 11 with an opening at the top, a cup cover 12 arranged at the opening of the cup body, and two sets of locking components with the same structure that can press the cup cover at the opening of the cup body are arranged next to the cup body, and both sets of locking components use the locking components with the above structure, and the two sets of locking components are symmetrically arranged on both sides of the cup body, see Fig.17 , 18 shown.
