The central regions of the third terminal 31 and the fourth terminal 32 extend towards the knob 5 and press against the first extension 52, and the central region of the five springs extends towards the knob 5 and presses against the first extension 52.

[0040] When the knob 5 is rotated to the point where the pressing part 54 presses against the first spring 23: the end of the second spring 24 near the first terminal 21 presses against the second terminal 22, and the end of the second spring 24 away from the first terminal 21 presses against the metal sheet 64; the middle extension area of ​​the third spring 34 and the middle extension area of ​​the fourth spring 35 fall into the first limiting groove 55 respectively, and at the same time, the end of the third spring 34 away from the third terminal 31 forms a gap with the fourth terminal 32, and the end of the fourth spring 35 away from the third terminal 31 forms a gap with the fifth terminal 33; the middle extension area of ​​the fifth spring 43 falls into the second limiting groove 56, and at the same time, the end of the fifth spring 43 away from the sixth terminal 41 forms a gap with the seventh terminal 6142.

This design makes it easier for the pressing part 54 to press against the first spring 23.

[0046] The fifth spring 43 has a seventh welding contact (not shown) at the end away from the sixth terminal 41, which is directly opposite the seventh terminal 6142. The seventh terminal 6142 has an eighth welding contact (not shown) at the position directly opposite the seventh welding contact. This design makes it easier to achieve electrical connection between the fifth spring 43 and the seventh terminal 6142.

[0047] In this embodiment, the outer shell 11 and the top cover are both made of PPS (polyphenylene sulfide). The mounting plate 13, the first terminal 21 to the seventh terminal 6142, the temperature regulating plate 62, the adjusting screw, and the elastic pressure plate 25 are all made of nickel-plated iron. The first spring 23 and the second spring 24 are both made of beryllium copper. The third spring 34 and the fourth spring 35 are both made of phosphor bronze. The fifth spring 43 is made of stainless steel. The knob 5 is made of POM (polyoxymethylene resin). The metal plate 64 is made of bimetallic material and serves as a heating wire. The sixth spring 66 is made of stainless steel. The first welding contact 241 to the eighth welding contact are all made of Ag / Cu. Of course, depending on actual needs, the above parts can be replaced with materials of the same or similar properties. For example, conductive materials can be replaced with other conductive materials, and insulating materials can be replaced with other insulating materials.

[0048] In this embodiment, when the knob 5 is rotated to the point where the pressing part 54 does not press against the elastic pressure plate 25: the first welding contact head 241 and the second welding contact head 221 are in the normally open state, that is, they are not in contact. At this time, the load is heated and the PTC heating element 65 does not work; the third spring piece 34 and the fourth spring piece 35 both fall into the first limiting groove 55, the third welding contact head 341 and the fourth welding contact head 321 are in the normally open state, that is, they are not in contact, the fifth welding contact head 351 and the sixth welding contact head 331 are in the normally open state, that is, they are not in contact; the fifth spring piece 43 falls into the second limiting groove 56, the seventh welding contact head and the eighth welding contact head are in the normally open state, that is, they are not in contact. At this time, in conjunction with the indicator light, the indicator light can be turned off.

[0049] In this embodiment, when the knob 5 is rotated to the point where the pressing part 54 presses against the elastic pressure plate 25: the first welding contact 241 and the second welding contact 221 are in a normally closed state, that is, they are in contact to achieve electrical connection, and the load and PTC heating element 65 are working at this time; the third spring 34 and the fourth spring 35 have not fallen into the first limiting groove 55, the third welding contact 341 and the fourth welding contact 321 are in a normally closed state, that is, they are in contact, the fifth welding contact 351 and the sixth welding contact 331 are in a normally closed state, that is, they are in contact; the fifth spring 43 has not fallen into the second limiting groove 56, the seventh welding contact and the eighth welding contact are in a normally closed state, that is, they are in contact, and at this time, in conjunction with the indicator light, the indicator light can be lit.

[0050] When the energy regulating device 100 in this embodiment is turned on, the metal sheet 64 begins to heat up, and the current flows in parallel into the heating resistor in the cooking area. The metal sheet 64 is heated, thereby changing its shape and triggering the relevant contacts. When the knob 5 is rotated, the pressing part 54 changes the distance between the metal sheet 64 and its relevant contacts. The size of this distance can change the interval between circuit connection and disconnection. At this time, the circuit can be repeatedly connected and disconnected by adjusting a longer or shorter time interval to achieve temperature control of the heating element. If set to the highest control point, the power will be continuously output, which is achieved by the pressing position of the pressing part 54 on the knob 5.

[0051] Compared with related technologies, the energy regulating device 100 of this utility model, through the design of three switching components and their triggering methods, not only improves the regulation range of the energy regulating device 100 through the design of the first switching component 2, the second switching component 3 and their triggering methods, and the temperature regulating component 6, but also allows the heating process to continue continuously under preset conditions, thereby enabling its output power to reach 100% of the rated output, making it suitable for high-power equipment applications. At the same time, the third switching component 4 and its triggering method can also add an indication effect. In addition, by controlling the ratio of current on time to circuit off time, the energy regulating device 100 can achieve higher output power, suitable for equipment requiring high power such as heating and frying, while also providing lower output power, suitable for equipment requiring lower power such as slow cooking.

[0052] It should be noted that the various embodiments described above with reference to the accompanying drawings are only illustrative of the present invention and not intended to limit its scope. Those skilled in the art should understand that any modifications or equivalent substitutions made to the present invention without departing from its spirit and scope should be covered within the scope of the present invention. Furthermore, unless the context otherwise requires, singular terms include plural forms, and vice versa. Additionally, unless specifically stated otherwise, all or part of any embodiment may be used in conjunction with all or part of any other embodiment.
