The outer cylinder 32 is movably installed on the inner cylinder 31, and the cylinder cover 36 is movably installed on the outer cylinder 32. A limiting component 4 is also installed on the stove plate 1. The outer cylinder 32 is limited and fixed by the limiting component 4, which can effectively protect the thermocouple probe 2 in an idle state, reduce stains on the surface of the thermocouple probe 2, and improve the performance of the flameout protection solenoid valve. In addition, the protection component 3 is limited and fixed by the limiting component 4, which is convenient for operation and disassembly.

The lower thread of the inner cylinder 31 is installed inside the thread groove 5. The setting of the thread groove 5 is convenient for fixing and installing the inner cylinder 31, and convenient for disassembly and assembly of the inner cylinder 31. The thermocouple probe 2 is located in the inner center of the inner cylinder 31 and the outer cylinder 32. When gas is not in use, the thermocouple probe 2 can be effectively protected to reduce stains attached to the surface of the thermocouple probe 2.

[0028] Among them, a slide rail 311 is integrally formed on the outer wall of the inner cylinder 31, and a slide groove 321 is opened on the inner wall of the outer cylinder 32. The slide groove 321 is slidably connected to the slide rail 311. The outer cylinder 32 is vertically lifted and lowered on the inner cylinder 31. When the outer cylinder 32 is at the lower part, the thermocouple probe 2 is in an exposed working state and can sense the flame.

When the thermocouple probe 2 is in the working state, the outer cylinder 32 moves downward, and the screw 43 is rotated to make the limit plate 44 press against the abutment plate 34 to limit the outer cylinder 32. When the thermocouple probe 2 is in the idle state, the screw 43 is rotated to separate the limit plate 44 from the abutment plate 34, and the spring 42 automatically drives the outer cylinder 32 to rise and perform top pressure to limit the position, which is convenient to use.

[0031] Among them, the fixing rod 41 includes a rod body and a limiting circular plate fixedly connected to the top of the rod body.
