Through heating and the reaction of multiple sets of sensors, such integrated processing can better process the gas.

[0012] (2) The present application operates through the suction fan. The wind force generated in the duct causes the fan blades to rotate, thereby driving the rotating rod to rotate, so that the rotating rod drives the baffle rod fixedly connected to its side to rotate. The baffle rod restricts the limit rod so that it drives the impact plate to hit the filter, thereby cleaning the filter and preventing dust accumulation from affecting the ventilation effect.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0021] A suction fan 8 is fixedly connected in the shell 1, an air inlet 5 is fixedly connected to the side of the shell 1, an air inlet pipe 6 is fixedly connected to the side of the air inlet 5, one end of the air inlet pipe 6 passes through the shell 1 and is fixedly connected to the air inlet 5 and is fixedly connected to the shell 1, and the other end is fixedly connected to the bottom end of the suction fan 8, a filter screen 7 is fixedly connected in the air inlet pipe 6, an air outlet pipe 9 is fixedly connected to the side of the suction fan 8, a filter screen 2 10 is fixedly connected in the air outlet pipe 9, a heating plate 11 is fixedly connected in the air outlet pipe 9, the heat generated by the heating plate 11 accelerates the diffusion speed of the gas molecules to be detected, and increases the reaction rate between the detected gas and the sensor, a sensor 12 is fixedly connected in the air outlet pipe 9, a sensor line 13 is fixedly connected to the bottom end of the sensor 12, and a signal line 13 is fixedly connected to the bottom end of the sensor line 13 The processor 14, the signal processor 14 can amplify, filter, and linearize the information transmitted by the sensor. The side of the signal processor 14 is fixedly connected with a sensor line 2 15, and the side of the sensor line 2 15 is fixedly connected with an output interface 16. In this application, by turning on the suction fan 8, the gas to be detected is sucked in through the air inlet 5, and then filtered through the filter 1 7 and the filter 2 10, it enters the area where the sensor 12 is located, and after the detection gas is heated by the heating plate 11, the reaction of the gas and the sensor 12 is accelerated. Then, the signal processor 14 amplifies, filters, and linearizes the signal received by the sensor 12 and then transmits it through the output interface 16. Through heating and the reaction of multiple groups of sensors 12, such integrated processing can better process the gas.

[0022] When this embodiment is used, the suction fan 8 is turned on during operation. At this time, the suction fan 8 is working, and suction is generated at the position of the air inlet 5 to suck in the gas to be detected. The gas is then filtered by the filter 7 and enters through the air inlet pipe 6, then enters the air outlet pipe 9 and is filtered by the filter 10, and then enters the area where the heating plate 11 is located. Under the heating of the heating plate 11, the diffusion speed of the gas molecules to be detected is accelerated, and the reaction rate between the detected gas and the sensor 12 is increased. Subsequently, the three groups of sensors 12 transmit the signals received in the gas to the signal processor 14 through the sensor line 13, and the received signals are amplified, filtered, and linearized by the signal processor 14, and then transmitted to the output interface 16 through the sensor line 2 15, and the received information is transmitted through the output interface 16. Example

[0023] See also Figure 4-5, on the basis of the first embodiment, a dust cleaning mechanism is added, the dust cleaning mechanism includes a support frame 17, the support frame 17 is fixedly connected with the air inlet pipe 6, a rotating rod 18 is rotatably connected in the support frame 17, a fan blade 19 is fixedly connected to the side of the rotating rod 18, a blocking rod 18 is fixedly connected to the side of the rotating rod 18, one end of the rotating rod 18 is rotatably connected to the support frame 17, and the other end is rotatably connected to the side of the filter screen 7. When the fan blade 19 drives the rotating rod 18 to rotate due to the uneven distribution of wind force, the rotating rod 18 is then restricted to rotate between the support frame 17 and the filter screen 7. A fixing frame 21 is fixedly connected in the air inlet pipe 6, a limiting rod 22 is slidably connected in the fixing frame 21, and a collision plate 24 is fixedly connected to the side of the limiting rod 22. A spring 23 is fixedly connected to the side of the impact plate 24, one end of the spring 23 is fixedly connected to the side of the impact plate 24, and the other end is fixedly connected to the side of the fixing frame 21. When the movement of the limit rod 22 is restricted by the baffle rod 20, it will drive the impact plate 24 to stretch the spring 23, and the subsequent elastic force of the spring 23 will cause the impact plate 24 to reset. The present application works through the suction fan 8, and the wind force generated in the air intake pipe 6 causes the fan blades 19 to rotate, thereby driving the rotating rod 18 to rotate, so that the rotating rod 18 drives the baffle rod 20 fixedly connected to its side to rotate, and the baffle rod 20 restricts the limit rod 22 so that it drives the impact plate 24 to hit the filter 7, thereby cleaning the filter 7 to prevent dust accumulation from affecting the ventilation effect.

[0024] During use, based on the first embodiment, when the suction fan 8 is working, wind force is generated in the air intake pipe 6. The uneven wind force causes the fan blades 19 to rotate. As the fan blades 19 rotate, the rotating rod 18 fixedly connected thereto rotates in the support frame 17. The rotation of the rotating rod 18 causes the blocking rod 20 to rotate. As the blocking rod 20 rotates, it will subsequently contact the inclined position of the limiting rod 22. As it and the blocking rod 20 continue to rotate, it will limit the movement of the limiting rod 22 toward the direction of the filter screen 7. At this time, the limiting rod 22 will push the impact plate 24 to hit the filter screen 7, shaking off the dust and other debris on it, and at the same time stretching the spring 23. As the blocking rod 20 continues to rotate, it will no longer contact the limiting rod 22. At this time, it is affected by the elastic force of the spring 23, so that the impact plate 24 is reset. As the rotating rod 18 continues to rotate, a reciprocating impact is finally formed, thereby cleaning the dust on the filter screen 7.

[0025] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
