In other embodiments, the number of the protrusions 214 may be 1 or three, and the number of the elastic arms 315 corresponds to the number and the arrangement positions of the protrusions 214.

In order to limit the penetrating position of the sensor holder 21 relative to the mounting through hole 311, a mounting limiting surface 321 for limiting the position of the sensor holder 21 is formed on one surface of the mounting plate portion 32 away from the elastic arm 315, and the end surface of the blocking edge portion 213 can abut against the mounting limiting surface 321 to limit the maximum depth of the sensor holder 21 inserted into the mounting through hole 311.

In order to ensure that the temperature detection assembly 2 is reliably abutted with the inner pot 5, the temperature detection device is further provided with an elastic member 4, the elastic member 4 is sleeved on the main body column part 211, one end of the elastic member 4 abuts against the flange part 212, and the other end of the elastic member 4 abuts against the mounting boss 313. When the sensor holder 21 is mounted in place with the mounting member 3, the resilient member 4 is in a compressed state. Thereby, the tip of the sensor cover 22 can be brought into close contact with the inner pot 5 by the elastic force of the elastic member 4.

Further, the main body tube 31 has an installation plate 32 extending radially outward toward one end face of the sensor holder 21, the installation plate 32 is provided with an arc plate 34 disposed coaxially with the installation through hole 311, and the inner side wall of the arc plate 34 is provided with the above-mentioned screwing portion 35.

In order to avoid the interference between the temperature detecting assembly 2 and the wire spool 1, a limiting cylinder part 33 coaxial with the mounting through hole 311 is convexly arranged at one end of the mounting plate part 32 facing the sensor cover 22, a mounting limiting surface 321 is formed at the inner side of the limiting cylinder part 33, the blocking edge part 213 is positioned at the inner side of the limiting cylinder part 33, and the insertion groove 36 is formed between the limiting cylinder part 33 and the arc-shaped connecting part 223.

In the present embodiment, the mounting plate portion 32 has a D-shaped structure, and the two arc-shaped connecting portions 223 are respectively located at two ends of the mounting plate portion 32 for fool-proofing.

In the present embodiment, the sensor holder 21 is rotatably engaged with the main body tube 31. In other embodiments, the connection between the sensor holder 21 and the main body tube 31 may be a snap connection, a screw connection, or other connection forms, which will not be described herein.
