[0035] The spring 45 is arranged on the top of the retaining ring 4 , and a limiting plate 44 is fixedly installed on the top of the sliding rod 43 .

[0036] The baffle 47 is disposed at the bottom of the baffle ring 4 .

[0037] The front side of the fixed frame 2 is rotatably connected with a door body 21 , and one side of the fixed frame 2 is fixedly mounted with a window body 22 .

[0038] A mounting frame 24 is fixedly mounted on one side of the inner side surface of the fixing frame 2 , and a buzzer 25 is fixedly mounted inside the mounting frame 24 . The buzzer 25 is arranged on one side of the window 22 .

[0039] When in use, the flame detection assembly 27 is arranged on the side of the flame nozzle and at a certain distance from the flame nozzle. When in use, an ultraviolet flame detector is installed on the flame detection assembly 27, which emits ultraviolet light to the nozzle of the bread toasting device, thereby monitoring whether the flame at the nozzle of the bread toasting device is extinguished;

[0040] When the induction switch 48 is turned on and the flame detection component 27 detects that the flame is extinguished, the alarm sound emitted by the buzzer 25 is different, so that the user can know in time whether the flame is extinguished due to gas failure or the flame is extinguished suddenly, so that the user can make corresponding treatment in time;

[0043] When in use, the user installs the protection tube 1 on the gas pipeline through the connecting tube 11, and then the user installs the flame detection assembly 27 on the side of the top cover of the baking bag device. Then the user ventilates the gas pipeline. At this time, the gas enters the inner side of the first guide tube 3 through the connecting tube 11, and the baffle 47 is pushed by the gas pressure of the gas, so that the baffle 47 moves downward, driving the slide bar 43 to move downward, so that the spring 45 is compressed. At this time, the gas enters the interior of the flame nozzle through the solenoid valve 31 and the second guide tube 32. Then the user ignites the flame nozzle and detects the flame through the flame detection assembly 27. When the flame goes out, After the flame detection component 27 detects, it transmits the signal to the controller 23 through the data line 26. At this time, the controller 23 controls the buzzer 25 to alarm, and at the same time, the solenoid valve 31 will be closed through the control of the controller 23; when the gas is used up, due to the lack of gas to push the baffle 47, the elasticity of the spring 45 will drive the slide bar 43 to move upward, so that the slide bar 43 drives the baffle 47 to move upward, so that the baffle 47 drives the induction switch 48 to move upward and contact the contact plate 42, so that the induction switch 48 is started, and a signal is sent to the controller 23, so that the controller 23 controls the buzzer 25 to alarm.

[0044] Compared with the related art, the flameout and gas failure alarm device for bun baking machine provided by the utility model has the following beneficial effects:

[0045] By means of the cooperation of the flame detection assembly 27, the protection tube 1, the controller 23, the buzzer 25, the first guide tube 3, the solenoid valve 31, the second guide tube 32 and other structures, when the bun toaster suddenly goes out, the flame can be detected by the flame detection assembly 27, and the signal can be transmitted to the controller 23 in the first time, so that the buzzer 25 can sound an alarm and the solenoid valve 31 can be closed to avoid gas leakage and danger.
