[0040] FIG14 is a structural diagram of the locking cover in FIG13 . Best Mode for Carrying Out the Invention

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] As shown in Figures 1 to 10 , the food processor with easily removable blades of the present invention comprises a bottom cover 1 and a cup body 2. A cup cavity 21 for accommodating materials is provided above the cup body 2, and a motor 3 is fixed below the cup body 2. The upper portion of the motor shaft 31 passes through the bottom wall of the cup body 2 and extends into the cup cavity 21 of the cup body 2. A removable blade 4 is threadedly connected to the upper portion of the motor shaft 31. A positioning portion 311 is provided at the lower portion of the motor shaft 31. The bottom cover 1 is provided with a removable locking cover 5. The locking cover 5 is provided with a locking portion 51 that can accommodate and lock the positioning portion 311 of the lower portion of the motor shaft 31.

[0043] Moreover, the bottom cover 1 is provided with an iron block 12 , and the locking cover 5 is provided with a first magnet 10 and a second magnet 13 that can attract the iron block 12 . The first magnet 10 and the locking portion 51 are symmetrically distributed on both sides of the second magnet 13 .

[0044] Furthermore, a control circuit board 8 and a magnetic induction switch 9 are provided on the bottom cover 1. The magnetic induction switch 9 and the motor 3 are electrically connected to the control circuit board 8. One end of the locking cover 5 is provided with a first magnet 10 that can control the magnetic induction switch 9 to be turned on or off.

[0045] In addition, both sides of the locking cover 5 are provided with a recess 17 for easy operation.

[0046] That is, when removing or installing the blade 4, one only needs to reach into the recess 17, then pull up the locking cover 5, and rotate the locking cover 5. When the locking cover 5 is rotated to the designated position, the first magnet 10 and the locking portion 51 are swapped, and the locking portion 51 is relatively locked with the positioning portion 311 at the lower part of the motor shaft 31. At the same time, under the magnetic attraction of the second magnet 13 and the iron block 12, the locking portion 51 is firmly locked with the positioning portion 311 at the lower part of the motor shaft 31, thereby locking the motor shaft 31. This prevents the blade 4 from rotating during operation, making it easier to remove or install the blade 4.

[0047] At this time, since the first magnet 10 is away from the magnetic induction switch 9, the magnetic induction switch 9 is disconnected, and the control circuit board 8 and the motor 3 stop working.

[0048] After the blade 4 is removed, the locking cover 5 is similarly rotated to separate the locking portion 51 from the positioning portion 311, unlocking the motor shaft 31. When rotated to the designated position, the first magnet 10 and the locking portion 51 return to their reversed positions. The first magnet 10 magnetically connects to the magnetic induction switch 9, closing the magnetic induction switch 9 and energizing the control circuit board 8 and motor 3 for normal operation. This stable structure enhances safety and ensures product quality.

[0049] In practical applications, the bottom cover 1 is provided with a third magnet 14 , the locking cover 5 is provided with a second magnet 13 that can attract the third magnet 14 , and the first magnet 10 and the locking portion 51 are symmetrically distributed on both sides of the second magnet 13 .

[0050] In this way, the third magnet 14 replaces the iron block 12 to strengthen the magnetic effect, which can also achieve locking of the motor shaft 31 during disassembly and assembly, thereby improving the structural stability during disassembly and assembly.

[0051] 1 to 10 , the cross-section of the positioning portion 311 at the lower portion of the motor shaft 31 is further detailed. The cross-section of the positioning portion 311 is in the shape of a straight line, a cross, a triangle, a rectangle, a square, a hexagon, or a plum blossom. The cross-section of the locking portion 51 is the same as or similar to that of the positioning portion 311.

[0052] This figure only shows that the cross section of the positioning portion 311 at the lower portion of the motor shaft 31 is in a straight line shape, and the cross section of the locking portion 51 is in a corresponding straight line shape.

[0053] The locking portion 51 and the positioning portion 311 of this structure have a simple structure, can strengthen the locking structure, facilitate the assembly and disassembly operation of the blade 4, and are practical and reliable.

[0054] The bottom cover 1 is provided with a recessed chamber 11 for accommodating the locking cover 5 and preventing the locking cover 5 from swinging, two hollowed-out portions 15 for accommodating the locking portion 51 and the first magnet 10 respectively, and a recessed cavity 16 for accommodating the second magnet 13 .

[0055] The structure of the recessed chamber 11, the hollow portion 15 and the concave cavity 16 is coordinated to achieve a compact structure, enhance structural integrity, ensure structural performance and ensure the aesthetics of the product.

[0056] Referring to Figures 1 to 12 , the food processor further comprises a cleaning brush 6. The blade 4 is provided with a screw 7 threadedly connected to the upper portion of the motor shaft 31. The cleaning brush 6 has an opening 61 for receiving the head of the screw 7 of the blade 4 or a claw 62 for engaging the blade 4. The cleaning brush 6 has a brush head 63 at one end, and the opening 61 or the claw 62 is provided at the other end.

[0057] During use, the screw 7 can be separated from the blade 4, or the screw 7 can be integrated with the blade 4. Subsequently, the cleaning brush 6 is provided with a corresponding opening 61 or a claw 62 for engaging the blade 4.

[0058] Furthermore, the cross-section of the head of the screw 7 is in the shape of a straight line, a cross, a triangle, a rectangle, a square, a hexagon, or a plum blossom. The cross-section of the opening 61 of the cleaning brush 6 is the same as or similar to the cross-section of the head of the screw 7.

[0059] When the blade 4 is disassembled, the motor shaft 31 is in a locked state, and the opening 61 of the cleaning brush 6 is clamped on the screw 7, or the claw 62 is clamped on the blade 4, and then the screw 7 or the blade 4 is turned to disassemble the screw 7 and the blade 4.

[0060] The cleaning brush 6 of the product can be used as a cleaning tool and also as a tool for disassembling and assembling the blade 4. The cleaning brush 6 has a simple structure, is easy to operate, has diverse uses, and is practical and reliable. Modes for Carrying Out the Invention

[0061] As shown in Figures 13 and 14, the food processor of the third embodiment of the present invention is different from the first embodiment in that a micro switch 81 is used instead of the magnetic induction switch 9, and the locking cover 5 does not need to be provided with the first magnet 10. The micro switch 81 is provided on the bottom cover 1, and the micro switch 81 and the motor 3 are electrically connected to the control circuit board 8 respectively. The locking portion 51 is provided with a protruding wall 52 that can trigger the micro switch 81 to trigger and disconnect the micro switch 81; when the locking portion 51 of the locking cover 5 is firmly locked on the positioning portion 311 at the lower part of the motor shaft 31, the protruding wall 52 of the locking portion 51 will also trigger the micro switch 81 to disconnect the micro switch 81. When the locking cover 5 is removed, the protruding wall 52 of the locking portion 51 no longer triggers the micro switch 81, and the micro switch 81 will be turned off, and the food processor can be powered on and operate. After the locking cover 5 is removed, it can be rotated 180 degrees and then fixed to the bottom cover 1. When the locking cover 5 is fixed to the bottom cover 1 after being rotated 180 degrees, the locking portion 51 is no longer locked on the lower portion of the motor shaft 31, so the protruding wall 52 will not trigger the micro switch 81. The micro switch 81 will be closed, and the food processor can be powered on and operated. The remaining structure and beneficial effects of this embodiment are consistent with the first embodiment and will not be repeated here.

[0062] The above-mentioned specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the food processor with convenient detachable blades of the present invention is within the protection scope of the present invention.
