According to a first embodiment of the heater of the present application, as shown in fig. 1 to 5, the heater includes a case assembly 1 and a guide rod 2, and the guide rod 2 is in limited connection with the case assembly 1. The box assembly 1 comprises at least one first limiting part 11, the guide rod 2 comprises a rod part 21 and at least one second limiting part 22, and the first limiting part 11 and the second limiting part 22 are in concave-convex fit. Along the radial direction of the lever portion 21, the lever portion 21 has a rotation center 211, and the profile of the cross section of the second stopper portion 22 includes a first point 221 and a second point 222, and the distance from the first point 221 to the rotation center 211 is greater than or less than the distance from the second point 222 to the rotation center 211. When the heater is in a working state, working medium flows in the heater, and the working medium has a certain impact on the guide rod 2 when flowing, so that the guide rod 2 is easy to rotate, and the heating effect of the heater is reduced. The distance from the first point 221 to the rotation center 211 is greater than or less than the distance from the second point 222 to the rotation center, at least part of the second limiting part 22 is of an eccentric structure, and when the first limiting part 11 and the second limiting part 22 are in concave-convex fit, the box assembly 1 can limit the rotation of the guide rod 2 to a certain extent, so that the heating effect of the heater is better.

It should be noted that, when the guide rod 2 is in limited connection with the box assembly 1, the guide rod 2 will rotate relative to the box assembly 1 within a preset range of angles, and the preset range of angles is generated based on the manufacturing error, the assembly error and other reasons of the guide rod 2 and the box assembly 1.
