[0002] Ambient air monitoring is a process of evaluating and monitoring the air quality in a specific area by using gas sensors and other detection equipment. This detection can help us understand the levels of pollutants, harmful gases and other air quality indicators in the environment. Various pollutants may exist in the ambient air, such as particulate matter (PM2.5, PM10), volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), etc.; detecting the concentration of these pollutants can evaluate the air quality and the degree of environmental pollution.
[0003] When the existing ambient air detection components are performing detection, factors such as wind, airflow and ventilation in the environment will cause the flow of odor molecules in the air, which will interfere with the detection results. As a result, the air samples obtained at certain locations or time points cannot accurately represent the air quality of the entire environment, resulting in inaccurate detection of ambient air. At the same time, the number of air samples detected at a single time is limited, which cannot fully reflect the complexity and variability of the ambient air, and lacks an assessment of the odor threshold. Considering the detection accuracy of ambient air, an ambient air detection component with an odor threshold is proposed to solve the above problems. Summary of the invention

[0032] A gas detection seat 6 is mounted on one side of the gas detection box 2 , and an axial hole seat 61 is installed on the gas detection seat 6 .
[0033] In this embodiment, multiple sensors are installed on the set ambient air detection component 3 for detecting the ambient air. The set ambient air detection component 3 drives multiple sensors to detect at one time. The ambient air detection component 3 can detect multiple parameters of the ambient air in the gas detection box 2 in a short time, thereby realizing rapid feedback and obtaining the detection results of the ambient air in time. At the same time, the odor sensor 39 can detect harmful odors in the air, and then perform odor threshold detection. By analyzing and comparing the detection results of the odor sensor 39, it can be determined whether the threshold of the harmful odor is exceeded, thereby providing timely alarms and protective measures.
[0034] It should be noted that by setting up the ambient air detection component 3 to drive multiple air detection sensors at a time, and combining with the ambient air extracted by the fan 8 to perform odor threshold detection, multi-parameter comprehensive detection, rapid detection and feedback, and odor threshold detection can be achieved. Compared with traditional air detection, it helps to improve the precision and accuracy of ambient air detection and provide more reliable data support for environmental protection and health management.
[0035] See also Figure 3 , Figure 6 In order to detect the ambient air and detect the odor threshold, the ambient air detection component 3 in this embodiment includes two push rod motors 31 mounted on the chassis 1, the output ends of the two push rod motors 31 are connected to a connecting seat 34, the other side of the two connecting seats 34 is jointly equipped with a positioning plate 35, one side of the positioning plate 35 is installed with a mounting seat 36, and the mounting seat 36 is vertically installed with a gas sensor 38, an odor sensor 39 and a temperature and humidity sensor 381;
[0036] A mounting groove 361 is formed on the mounting seat 36, and a plurality of positioning holes are opened in the mounting groove 361. The gas sensor 38, the odor sensor 39 and the temperature and humidity sensor 381 are respectively assembled in one of the positioning holes; a plurality of detection holes 62 are opened vertically on the axial hole seat 61, and there is a spacing between each detection hole 62; there is a spacing between the gas sensor 38, the odor sensor 39 and the temperature and humidity sensor 381, and the detection parts of the gas sensor 38, the odor sensor 39 and the temperature and humidity sensor 381 are adapted to the aperture of the detection hole 62 and correspond to one detection hole 62 respectively.
[0037] In the present embodiment, in actual use, the operator controls the control box 4 to make the fan 8 work and draw air into the gas detection box 2. Then, the operator connects the power supply to the push rod motor 31 to make the set push rod motor 31 work. Through the connection between the set connecting seat 34 and the positioning plate 35, when the output end of the push rod motor 31 is pushed out, the set positioning plate 35 can follow the radial movement, and then the mounting seat 36 set on the positioning plate 35 can follow the movement, and the moving distance is controlled until the gas sensor 38, the temperature and humidity sensor 381 and the odor sensor 39 on the mounting seat 36 move straight through The detection hole 62 and the top plate 21 are located in the gas detection box 2. The gas sensor 38 and the odor sensor 39 can be used to perform threshold detection on the air in the gas detection box 2. Through the coordinated detection of the gas sensor 38, the odor sensor 39 and the temperature and humidity sensor 381, a variety of parameters in the ambient air can be comprehensively detected. The gas sensor 38 can detect the concentration of pollutants in the air, and the odor sensor 39 can detect the presence of harmful odors. The temperature and humidity sensor 381 can provide environmental temperature and humidity information. Through various detections of the ambient air, the quality and characteristics of the ambient air can be fully understood and odor threshold detection can be performed.
[0038] It should be noted that, in order to improve the stability of the output end of the push rod motor 31 during sliding, in a preferred embodiment, Figure 3 As shown in the figure, one side of the chassis 1 is rectangularly provided with four limit shafts 37, and the other ends of the four limit shafts 37 are commonly connected to a push plate 32, and the push plate 32 is provided with two slots, and linear bearing sleeves 33 are assembled in the two slots; the output ends of the two push rod motors 31 respectively pass through one of the linear bearing sleeves 33 and are connected to the connecting seat 34; through the sliding cooperation between the output end of the push rod motor 31 and the linear bearing sleeve 33, in actual use, the linear bearing sleeve 33 can provide stable sliding support, so that the movement of the output end of the push rod motor 31 in the radial direction is smoother, and the shaking, deviation and vibration of the motor guide rod at the output end can be reduced, thereby improving the operation stability and accuracy of the push rod.
[0039] See also Figure 1-2 , Figure 5 In order to extract ambient air for detection by the ambient air detection component 3, an air intake valve 7 is installed on the upper end surface of the top plate 21 in this embodiment, and the air intake valve 7 is arranged opposite to the fan 8; a plurality of probe holes 22 are opened vertically on the outer side of the gas detection box 2, and each of the probe holes 22 has a spacing, and the spacing and diameter of the probe holes 22 and the detection holes 62 are the same; a control box 4 is also installed on the chassis 1, and a control switch for controlling the power supply is provided on the control box 4, and the control switch is electrically connected to the fan 8 and the ambient air detection component 3 respectively.
[0040] In the present embodiment, in actual use, the operator opens the air inlet valve 7 so that the slot provided on the top plate 21 is connected to the outside world, and then connects the power supply to the fan 8 to make the fan 8 work. The outside air is drawn into the gas detection box 2 by the fan 8 for the ambient air detection component 3 to perform air detection. The slot can be opened and closed by the air inlet valve 7 provided on the other side of the slot, so that the operator can choose whether to introduce ambient air into the gas detection box 2 for detection as needed. When detection is required, the air inlet valve 7 is opened to allow the fan 8 to extract air; when detection is not required, the air inlet valve 7 is closed to stop extraction.
[0041] It should be noted that by controlling the opening and closing of the air intake valve 7, the influence of the external environment on the air in the slot can be isolated. When the air intake valve 7 is closed, the external air cannot enter the gas detection box 2, ensuring the independence and accuracy of the detection process.
[0042] The working principle of the above embodiment is:
[0043] Step 1: When testing the ambient air, the operator opens the air inlet valve 7 so that the notch on the top plate 21 is connected to the outside, and then connects the power supply to the fan 8 to make the fan 8 work, and the outside air is drawn into the gas detection box 2 through the fan 8. After a proper amount of air is drawn, the air inlet valve 7 is then closed to seal the gas detection box 2.
[0044] Step 2: After the air is drawn into the gas detection box 2, the push rod motor 31 is connected to a power source so that the push rod motor 31 is operated, and the output end is pushed out radially. The connection between the connecting seat 34 and the positioning plate 35 is made so that when the output end of the push rod motor 31 is pushed out, the positioning plate 35 can follow the radial movement, and then the mounting seat 36 set on the positioning plate 35 can follow the movement, and the moving distance is controlled until the gas sensor 38, the temperature and humidity sensor 381 and the odor sensor 39 on the mounting seat 36 move straight through the detection hole 62 and the top plate 21 and are in the gas detection box 2. The gas sensor 38 and the odor sensor 39 can perform threshold detection on the air in the gas detection box 2, and the temperature and humidity sensor 381 can perform temperature and humidity detection on the ambient air, and then the detection diversity and accuracy of the ambient air can be improved through sample comparison;
[0045] Step 3: After the air has been detected by the gas sensor 38, the temperature and humidity sensor 381 and the odor sensor 39, the operator opens the air intake valve 7 to allow the installed fan 8 to work and discharge the residual air.
