[0022] The utility model is further described below in conjunction with the accompanying drawings: as shown in the figure, a temperature controller with a pressure plate includes a base 1 and a support plate 2, and a temperature sensing mechanism 21 is provided on the support plate. The temperature sensing mechanism is used to drive the moving contact piece and the static contact piece to be disconnected, and also includes a boss 11, which is provided on the base, and a circumferential outer wall of the boss is provided with a sink 111; a pressure plate 3 is used to fix the power connection piece, and a top plate 31 is provided on the pressure plate, at least part of the top plate is provided in the sink, and the top end surface of the top plate is limitedly matched with the top inner wall of the sink. The temperature sensing mechanism can be a bimetallic strip, which drives the moving contact piece to break through the top rod. This is a prior art and will not be described in detail. The top plate has an elasticity that allows its top end face to be limitedly matched with the top inner wall of the sink. When installed, the top plate will deform. After it is in place, it will extend into the sink through elasticity and achieve limiting with the sink. Preferably, the two are planes that cooperate with each other. There can be a certain gap between the bottom end face of the top plate and the top inner wall of the sink. The power contact piece can be a moving contact piece or a static contact piece, and it can be integrated with the pole ring, which can also achieve the function of fixing and positioning the pole ring.

[0023] In this embodiment, as shown in the figure, the boss is arranged at the center of the base, and a through hole 112 is arranged on the boss for the pole needle 91 to pass through, so that the installation is more convenient.

[0024] In this embodiment, as shown in the figure, the pressure plate is provided with a fixing ring 32, and the fixing ring is sleeved on the circumferential outer wall of the boss. The pressure plate is sleeved on the outer wall of the boss, which is more convenient to install.

[0025] In this embodiment, as shown in the figure, at least two notches 33 are provided on the fixing ring, and the top plate is formed between the two notches. The circumferential outer wall of the boss may include a circular surface and a plane 113. The top plate is arranged opposite to the plane. The fixing ring is not a complete circular ring, but a part of it. The deformation can be better achieved through the setting of the notches.

[0026] In this embodiment, as shown in the figure, the base is provided with a fixing seat 15 and a through slot 14, and the pressing plate is provided with a protrusion 34, which is detachably connected to the through slot, and the lateral end surface of the protrusion is used to press the power connection sheet 92 against the side wall of the fixing seat. The protrusion is partially inserted into the through slot, and its side wall presses the power connection sheet to position it on the side wall of the fixing seat.

[0027] In this embodiment, as shown in the figure, the protrusion is provided with a first barb 341, and the fixing seat is provided with a second barb 151 that matches the first barb, so that the installation is more stable.

[0028] In this embodiment, as shown in the figure, a crossbeam 911 is provided on the pole needle, and the crossbeam cooperates with the upper end surface of the pressing plate to limit the position of the pressing plate.

[0029] In this embodiment, as shown in the figure, the front end surface of the top plate is provided with a protrusion, and the protrusion is provided with a slope 311, and the slope is used to slide with the outer wall of the boss to open the top plate when the pressure plate is installed. When installed, the slope cooperates with the side wall of the boss to open the top plate for installation, and after installation, the top plate relies on its own elastic force to come into the sink.

[0030] The top end surface of the top plate and the top inner wall of the sink are flat, which can better prevent the sink from falling out.
