Detailed Description
According to the electrothermal tube temperature controller assembly of the invention shown in figures 1-5, a water pipe is welded on an electrothermal tube 1, a metal fixing sheet 2 is fixed on the water pipe and is tightly connected with the electrothermal tube 1, and a temperature controller bracket 3 is fixed on the metal fixing sheet 2. The lower part of the main body of the temperature controller bracket 3 is suspended and has a proper height from the metal fixing piece 2. A double-layer metal sheet 4 is fixed on the metal fixing sheet 2 below the temperature controller bracket 3, the double-layer metal sheets 4 are overlapped and fixed together, the lower layer is contacted with the surface of the metal fixing sheet 2, and the upper layer is contacted with the lower end of the push rod 5. The push rod 5 is inserted into a push rod hole on the temperature controller bracket 3 and can move up and down freely along the push rod hole. The upper end of the push rod 5 is propped against the lower part of the first residual part 601 of the copper sheet A6. Two groups of copper sheets are symmetrically arranged on the temperature controller bracket 3, wherein one group is arranged between the lower 7 of the copper sheet A and the upper 6 of the copper sheet A, and the other group is arranged between the lower 8 of the copper sheet B and the upper 9 of the copper sheet B. The upper copper sheet A6 is arranged above the lower copper sheet A7, and the free end of the upper copper sheet A6 exceeds the free end of the lower copper sheet A to form a first residual part 601. The upper surface of the lower part 7 of the copper sheet A is fixedly provided with a conductive post 10, the lower surface of the upper part 6 of the copper sheet A is fixedly provided with a conductive post 10 corresponding to the lower part 7 of the copper sheet A, and the upper part 6 of the copper sheet A is communicated with the lower part 7 of the copper sheet A when the two conductive posts are contacted. The upper copper sheet B9 is arranged above the lower copper sheet B8, and the free end of the upper copper sheet B9 exceeds the free end below the copper sheet B to form a second residual part 901. The upper surface of the lower part 8 of the copper sheet B is fixedly provided with conductive posts, the lower surface of the upper part 9 of the copper sheet B is fixedly provided with conductive posts corresponding to the lower part 8 of the copper sheet B, and the lower part 8 of the copper sheet B is communicated with the upper part 9 of the copper sheet B when the two conductive posts are contacted. The arch bar A10 is fixed or integrally formed with a shaft, the shaft is placed in a U-shaped groove 12 on the temperature controller bracket 3, and the shaft can freely rotate along the same axis in the U-shaped groove of the temperature controller bracket. The rear 1001 of arch bar a presses against copper sheet B9 and the front 1002 of arch bar a presses against the first fusible rod 13. The first fusible rod 13 is made of plastic that is fusible at a certain temperature. The bottom of the first fusible rod 13 is contacted with the upper surface of the metal fixing piece 2, and when the metal fixing piece 2 reaches a certain temperature, the first fusible rod 13 is heated and melted. The arch bar B11 is fixed or integrally formed with a shaft which is arranged in a groove on the temperature controller bracket 3 and can coaxially rotate in the groove of the temperature controller bracket 3. The rear 1101 of arch B presses against the second fusible link 14 and the front 1102 of arch B presses over the axis of arch a10 or is offset to the rear 1001 of arch a by a distance such that the front 1102 of arch B can be lifted when the rear 1001 of arch a is lifted. The second fusible rod 14 is made of plastic that is fusible at a certain temperature. The bottom of the second fusible rod 14 is contacted with the upper surface of the metal fixing piece 2, and when the metal fixing piece 2 reaches a certain temperature, the second fusible rod 14 is heated and melted. A push rod hole is arranged on the temperature controller bracket 3, and the push rod 5 can freely move up and down in the push rod hole.

A spring 15 is arranged on the temperature controller bracket 3 below the second residual part 901 of the copper sheet B9, and the second residual part 901 of the copper sheet B9 is inserted into or fixed on the spring 15. Spring 15 maintains an upward thrust on copper sheet B9 during normal operation of electrothermal tube 1, and at the same time, copper sheet B9 produces an upward thrust on rear portion 1001 of arch bar a, and arch bar a10 produces an upward thrust on front portion 1102 of arch bar B.
When the electric heating tube 1 works abnormally and the temperature of the metal fixing piece 2 reaches the set abnormal temperature, the first fusible rod 13 or/and the second fusible rod 14 are heated and melted, and the arch rod A10 or the arch rod B10 is/are lack of support at one end, so that the upward thrust of the spring 15 pushes the copper sheet B to the upper part 9, the copper sheet B is lifted upwards to separate from the lower part 8 of the copper sheet B, and the electric heating tube 1 is powered off; or the double-layer metal sheet 4 is deformed and thickened by abnormal heating, the push rod 5 is jacked up, the push rod 5 can push the first residual part 601 of the copper sheet A6 upwards to jack the copper sheet A6 so as to separate from the copper sheet A7, and the electric heating tube 2 is powered off.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the present invention.
