The cleaning body 9 is inclinedly arranged near the side of the oil fume sensor 23, and is monitored normally above the oil fume sensor 23. When the cleaning body 9 is arranged at the bottom, the channel of the smoke extraction duct 1 is squeezed to the oil fume sensor 23 to complete the accelerated flow and concentration monitoring of the flue, thereby ensuring the monitoring of flue oil fume under various conditions. At the same time, the cleaning body 9 provides a position for cleaning the oil fume sensor 23 to avoid excessive restaurant oil fume. After long-term monitoring, the oil fume adheres to the outer surface of the oil fume sensor 23, causing inaccurate monitoring, which helps to maintain its good working condition.

[0039] When the air blowing body 15 is above the cleaning body 9 after the oil fume sensor 23 is cleaned, it is opened to blow air to the oil fume sensor 23 to accelerate air drying and ensure the cleanliness of the surface of the oil fume sensor 23. The control body 16 controls the operation of the ultrasonic generator 11 and the air blowing body 15.

[0040] Reference Figure 1-4 An auxiliary smoke inlet pipe 18 is welded on the lower surface of the smoke extraction pipe 1 , and an auxiliary baffle 17 is welded on the outer surface of the cleaning body 9 .

[0048] The implementation principle of an alarm embodiment for restaurant fume monitoring in this application is as follows:

[0049] The oil smoke of the equipment enters from the auxiliary smoke inlet pipe 18. When it passes through the oil smoke sensor 23 at the smoke extraction pipe 1, the oil smoke and relative temperature cause a change in resistance, and the corresponding internal circuit of the detection machine 19 changes, and the corresponding parameters are obtained. When the corresponding set parameters are reached, the detection machine 19 responds and issues an oil smoke alarm. The rotation of the second motor 25 drives the cylindrical cam 24 to rotate, and the corresponding groove drives the guide rod 22 to reciprocate and extend left and right, thereby driving the support tube 21 to move left and right as a whole, and the oil smoke sensor 23 also moves. The first motor 3 rotates, driving the driving wheel 4, the transmission belt 5, and the driven wheel 6 to rotate. The driven wheel 6 rotates simultaneously with the lifting rod 7, and the threaded groove below rotates, and the support frame 8 corresponds to The threaded hole ensures its up and down movement. The cleaning body 9 is set obliquely on the side close to the oil fume sensor 23. Normal monitoring is carried out above the oil fume sensor 23. When the cleaning body 9 is set at the bottom, the channel of the smoke extraction duct 1 is squeezed to the oil fume sensor 23, and the flue flow acceleration and concentration monitoring are completed to ensure flue oil fume monitoring under various conditions. When the oil fume sensor 23 is even above the ultrasonic generator 11, the oil fume sensor 23 can be cleaned to avoid excessive catering oil fume. After long-term monitoring, the oil fume adheres to the outer surface of the oil fume sensor 23, causing inaccurate monitoring, which helps to maintain its good working condition, improve accuracy and reliability, extend service life, reduce maintenance costs, and ensure safe production.
