[0003] Food processors similar to blenders that are driven from the bottom with a tool usually include both a blending function and a heating function. The blades often need to be replaced when performing different tasks.

[0004] Currently, replacing the knife requires removing the container and then replacing the entire knife assembly, which is cumbersome, and the knife assembly cannot be replaced if there are ingredients or liquids in the container or if it is not cleaned thoroughly. Food processors that only replace the knife head cannot identify the type of knife head or whether the knife head is installed. Summary of the invention

[0005] The object of the present invention is to provide a replaceable cutter head, a food processor capable of identifying the type of cutter head installation, whether the cutter head is installed, and a detachable component identification device.

[0006] The present invention provides a food processor, comprising a base and a vessel, wherein a knife assembly is installed in the vessel, and a power device is installed in the base, and the power device drives the knife assembly to operate;

[0007] The tool assembly comprises a tool shaft, a first through hole is formed at the axis of the tool shaft, a first push rod is installed in the first through hole; a tool head is detachably mounted on the tool shaft, and the tool head has a contact surface that abuts against the first push rod; an elastic member is also included, and the elastic member is used to push the first push rod to abut against the contact surface; the tool shaft and the tool head are connected in a hook-type manner; the elastic member can be located on the first push rod, in the indentation identification component, or on the transmission path between the two, and can be one elastic member or multiple elastic members;

[0008] A retraction identification component is installed in the base, and the first push rod is directly or indirectly connected to the retraction identification component. The direct or indirect connection here includes direct or indirect conflict. The retraction identification component is used to detect the axial retraction of the first push rod.

[0009] The beneficial effect of the food processor is that when the cutter head is installed on the cutter shaft, the contact surface pushes the first push rod to retract, and the retraction recognition component detects the retraction amount of the first push rod to recognize that the cutter head has been installed and the type of the installed cutter head.

[0010] Furthermore, the side of the knife shaft has a clamping protrusion; the knife head has a mounting hole adapted to the knife shaft, and the side of the mounting hole is provided with a clamping structure; the clamping structure includes a long through hole extending from the inner wall of the mounting hole to the outside, a groove recessed from one end of the long through hole toward the opening of the mounting hole, and a notch provided at the other end of the long through hole and adapted for the clamping protrusion to enter the long through hole; the contact surface is the bottom surface of the mounting hole.

[0011] The beneficial effect of adopting the above further scheme is: when installing the cutter head, align the installation hole with the cutter shaft so that the snap-on protrusion enters the long through hole from the notch, rotate the cutter head so that the snap-on protrusion reaches the position corresponding to the groove, and under the action of the elastic member, the snap-on protrusion is snapped into the groove to prevent the cutter from falling off. When removing the cutter head, first press and then rotate the cutter head in the opposite direction. In addition, it is also possible to judge whether the cutter head is correctly installed based on the indentation amount identified by the indentation identification component. When it is correctly installed, there must be a larger indentation amount first, and then it becomes an indentation amount that matches the cutter head. If the cutter head falls off, the indentation amount must be a larger indentation amount first, and then the indentation amount disappears, so it can be judged that the cutter has fallen off.

[0012] Furthermore, the cutter shaft can be detachably mounted with a variety of cutter heads; at least two of the multiple cutter heads have mounting holes with different depths.

[0013] The beneficial effect of adopting the above further solution is that the indentations caused by the installation holes of different depths are different, so a variety of tool heads can be identified.

[0017] The beneficial effect of adopting the above further solution is that the overall structure is simple and reasonable.

[0018] Furthermore, the lower end of the second push rod is rotatably connected to a feeler rod. In order to prevent the feeler rod from rotating and wearing the retract identification component, a bearing can be installed at the connection between the second push rod and the feeler rod; the feeler rod is connected to the retract identification component.

[0019] The beneficial effect of adopting the above further solution is: avoiding the wear of the indentation identification component by the rotation of the feeler rod, making it more durable.

[0020] Further, the indentation identification component includes a PCB board and a slider sliding along the surface of the PCB board;

[0021] A row of conductive contacts is arranged on the surface of the PCB board, and two electrical connection points are also arranged on the PCB board; each of the conductive contacts is connected to a resistor in a one-to-one correspondence, and each resistor has a different resistance value; two resistors corresponding to two adjacent conductive contacts are connected to different electrical connection points;

[0022] The slider is provided with a conductive member, which is used to slide along with the slider and electrically connect two adjacent conductive contacts in sequence during the sliding process;
