The stop arm 13223 is configured to further prevent the lug 1421 from leaving the slot 13221 to rotate with the connecting shaft 141.

As shown in fig. 2, 3 and 4, the large hole 1323 of the stepped hole 132 is adapted to receive a portion of the host 110, and the upper cover 130 is provided with the triggering structure 135. The trigger structure 135 can protrude out of the large aperture 1323 to trigger the detection switch 111, and the cooperation of the trigger structure 135 and the detection switch 111 is used to determine whether the host 110 is placed in the large aperture 1323. When the main body 110 is disposed in the large hole 1323, it will engage with the connecting teeth on the connecting shaft 141 to drive the connecting shaft 141 to rotate.

As shown in fig. 2 and 3, a part of the trigger structure 135 protrudes from a side surface of the large hole 1323, the trigger structure 135 is an elastic abutting member, and the detection switch 111 is a mechanical touch switch. The trigger structure 135 comprises a spring 1351 and an abutment 1352 contacting the spring 1351, under the action of the spring 1351 the trigger structure 135 by default protrudes the outer wall of the (lower part of the) upper cover 130 by the abutment 1352. During the process of closing the upper lid 130 on the cup opening 122, the abutting element 1352 moves into the large hole 1323 under the continuous abutting interference of the inner wall of the cavity 121 to trigger the detection switch 111.

Specifically, in the present embodiment, the operating switch 113 is disposed on the top end surface of the main body 110, and the motor 112 operates after both the detection switch 111 and the operating switch 113 are turned on. The abutting piece 1352 is provided with a first end and a second end, the spring 1351 is sleeved on the outer surface of the abutting piece 1352 and is located between the first end and the second end, the abutting piece 1352 enables the first end to protrude out of the outer wall of the upper cover 130 under the action of the spring 1351, the first end moves into the upper cover 130 after overcoming the elastic force of the spring 1351, and at the moment, the second end moves into the large hole 1323 to finally trigger the detection switch 111. As shown in fig. 3, the detection switch 111 is disposed at the lower end of the main body 110 (which is equivalent to an invisible setting, and is not easy to be touched by a user, and the main body 110 must be placed in the large hole 1323 during operation), a channel 115 leading to a triggering position (a triggering point of the detection switch 111) of the detection switch 111 is disposed on the side surface of the main body 110, and the setting size of the channel 115 is adapted to the shape of the second end. The surface of the first end contacting the cup rim 122 is an inclined surface inclined toward the cavity 121, the setting size of the cup rim 122 is larger than the setting size of the bottom of the cavity 121, and the side wall of the cavity 121 is an inclined surface inclined from the cup rim 122 toward the bottom of the cavity 121.

As shown in fig. 5, a protrusion 136 is disposed on the transition connection surface of the large hole 1323 and the small hole 1321, and a positioning hole (not shown) matching with the protrusion 136 is disposed on the host 110. The matching of the protrusion 136 and the positioning hole is used to limit the connection manner between the host 110 and the large hole 1323, so that after the host 110 is disposed in the large hole 1323, the position of the detection switch 111 corresponds to the position of the trigger structure 135.

Because the connecting sleeve 142 and the upper cover 130 are connected through the detachable structure in the above embodiment to prevent the rotation or continuous rotation between the connecting sleeve 142 and the upper cover 130, after the connecting sleeve 142 is connected with the upper cover 130 and the connecting shaft 141 is connected with the host 110, the movement of the knife assembly 140 in the axial direction is limited, and a preset gap is reserved between the bottom of the knife assembly 140 and the bottom of the cavity 121, so that the bottom of the knife assembly 140 is not in contact with the bottom of the cavity 121, the friction between the knife assembly 143 and the cavity 121 is reduced, the arrangement is energy-saving, the noise generated during the operation of the food processor can be reduced, and the user experience is improved. Since the motor 112 operates after the detection switch 111 and the operation switch 113 are both turned on, the operation safety of the food processor 100 is greatly improved, and the user experience is further improved.

While the principles and embodiments of this invention have been described above using specific examples, it is to be understood that the above embodiments are merely provided to assist in understanding the invention and are not to be construed as limiting the invention. Any minor modifications or equivalent replacements of the structural forms or constructions of the present invention made by the idea of the present invention should be included in the protection scope thereof by the ordinary skilled in the art.
