When the locking assembly 4 locks the machine body 1 and the container assembly 2, the locking piece 25 locks the cover 212 and the body 211, so that the cover 212 and the body 211 are prevented from being separated in the working process of the food processor 100, and the normal operation of the food processor 100 is ensured.

In order to understand the specific structure of the locking member 25, as shown in fig. 10 to 13, the locking member 25 includes a rod 251 and a guide rod 252, wherein the rod 251 is connected to the body 211 and can slide in a vertical direction relative to the rod 251, and the guide rod 252 is disposed on the machine body 1. When the body 1 is locked with the container assembly 2 by the locking assembly 4, one of the locking protrusions 42 pushes the guide bar 252, and the guide bar 252 pushes the rod 251 to move upward so that the tip of the rod 251 is located at the rear side of the push protrusion 2122 in the screwing direction, the cap 212 can be prevented from being unscrewed from the body 211. Through the compact and simple structure, the locking of the container assembly 2 and the machine body 1 and the simultaneous locking of the cover 212 and the body 211 are realized, and the use of the food processor 100 is facilitated.

Specifically, as shown in fig. 13, the guide rod 252 is rotatably connected to the body 1. As shown in fig. 11 and 12, the guide rod 252 includes a first arm 2521 and a second arm 2522 connected, the first arm 2521 being abutted against the lower end of the guide rod 252, one of the locking protrusions 42 having a triangular shape, the side of the triangle being capable of contacting the second arm 2522. As shown in fig. 13, when the locking protrusion 42 rotates clockwise, the free end of the second arm 2522 can slide along the side of the triangle, from the bottom of the side of the triangle to the top of the side of the triangle, that is, the free end of the second arm 2522 is applied with a radially outward pushing force, the guide rod 252 rotates clockwise relative to the body 1, and the free end of the first arm 2521 is tilted upward to jack up the rod 251 such that the top end of the rod 251 is located at the rear side of the push protrusion 2122 in the screwing direction, so that the rod 251 can restrict the cover 212 from being screwed to the body 211 in the opening direction.

In order to ensure that the free end of the first arm 2521 always abuts against the rod body 251, as shown in fig. 11 and 12, the first arm 2521 includes a first arm body 25211, a guide rod 25212, and two support arms 25213, the first arm body 25211 is connected with the second arm 2522, the two support arms 25213 are disposed at one end of the first arm body 25211 away from the second arm 2522, and two ends of the guide rod 25212 are respectively connected with the two support arms 25213. The rod body 251 is formed with a guide groove 2511 extending upward from a lower end thereof, and a guide bar 25212 is provided in the guide groove 2511 and is slidable along the guide groove 2511, and the guide bar 25212 can be restrained in the guide groove 2511 to avoid the free end of the first arm 2521 from being separated from the rod body 251.

In addition, as shown in fig. 10, the locking member 25 further includes a second restoring member 253, and when the body 1 is unlocked from the container assembly 2, the second restoring member 253 is used to move the rod 251 downward to restore the locking of the cover 212 and the body 211. Specifically, the second restoring member 253 may be a spring, one end of which is connected to the mounting cover 23, and the other end of which is connected to the rod 251.

As shown in fig. 6, the trigger mechanism 24 and the locking member 25 are located in the mounting cover 23, and the mounting cover 23 can prevent other external parts from affecting the movement of the trigger mechanism 24 or the locking member 25. To achieve the driving of the trigger mechanism 24 by the push protrusion 2122 and the limitation of the reverse movement of the push protrusion 2122 by the lock member 25, as shown in fig. 6, the outer side surface of the mounting cover 23 is formed with a slide groove 231 extending in the circumferential direction thereof, the slide groove 231 is formed with an opening 2311 at one side of the mounting cover 23, and the push protrusion 2122 can be inserted from the opening 2311 and slid along the slide groove 231 to be engaged with the trigger mechanism 24 and the lock member 25. In the conventional food processor 100, the trigger mechanism 24 and the locking member 25 are disposed in the handle, and the top end of the handle is provided with an upward chute, so that dust, impurities and dirt easily fall down in the chute 231 due to gravity and are difficult to clean. However, in the disclosed embodiment, as shown in fig. 10, the sliding groove 231 is located on the outer side surface of the mounting cover 23, and the push protrusion 2122 extends radially inward from the side edge of the cover body 2121. Since the chute 231 is located on the outer side surface of the mounting cover 23, dust, impurities and dirt are not likely to fall into the chute 231 by gravity, which helps to reduce the risk of dust, impurities and dirt being hidden in the chute 231.

To facilitate understanding of the above-described locking and unlocking processes of the food processing machine 100, the following description will now be made with reference to fig. 2, 3, 6, 10, 11, and 13:

the locking process is as follows: as shown in fig. 2 and 6, the container assembly 2 is mounted to the body 1, and the cover 212 is fastened to the body 211. The machine body 1 is provided with a mounting-in-place detecting mechanism for detecting whether the container assembly 2 is mounted in place on the machine body 1. After the container assembly 2 is in place, the operator rotates the cover 212 and the push protrusions 2122 enter the slide grooves 231 from the openings 2311 and slide along the slide grooves 231. As shown in fig. 10, the push protrusion 2122 slides along the inclined surface 2411 while contacting the trigger lever 241, so that the trigger lever 241 slides downward, the lower end of the trigger lever 241 abuts against the conductive member 272, the conductive member 272 moves downward and the first micro switch 271 is closed. The signal of the closing of the first micro switch 271 is transmitted to the controller, and the controller controls the driving assembly 3 shown in fig. 5 to operate, and the driving assembly 3 drives the locking ring 41 to rotate (e.g., clockwise) so that the locking protrusion 42 is inserted into the slot 221 shown in fig. 6, thereby locking the machine body 1 and the container assembly 2. Meanwhile, the locking protrusion 42 shown in fig. 13 pushes the guide bar 252 to rotate, and the first arm 2521 shown in fig. 11 pushes the rod 251 to move upward such that the tip of the push rod 251 is located at the rear end of the push protrusion 2122, thereby locking the cover 212 with the body 211.

The unlocking process is as follows: when the operation of the food processor 100 is completed, the controller controls the cutter driving motor to stop operating. The controller controls the driving assembly 3 shown in fig. 5 to operate, and the driving assembly 3 drives the locking ring 41 to rotate (e.g., counterclockwise) so that the locking protrusion 42 is withdrawn from the slot 221 shown in fig. 6, thereby unlocking the body 1 from the container assembly 2. The locking protrusion 42 is separated from the guide rod 252, so that the rod 251 moves downward to be reset under the action of the reset component 253, and the top end of the rod 251 moves to be below the push protrusion 2122 shown in fig. 6, so that an operator can rotate the cover 212 and remove the cover 212, and at the same time, the trigger lever 241 moves upward to be reset under the action of the first reset piece 242.
