Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example 1: As Figures 1-6 ,include The housing 100 is fixedly connected to the base 120 on the bottom outer wall of the housing 100; The filter assembly includes an air intake grille 200 and a filter installed at the bottom of the air intake grille 200. The filter includes a PM10 pre-filter, an activated carbon adsorption layer, and a HEPA filter element. The detection component includes a detection box 300, which houses a detection sensor. The bottom of the detection box 300 is connected to an exhaust box 350, and the bottom of the exhaust box 350 is connected to an air pump 360.

[0020] The specific application scenario of this embodiment is as follows: By setting up a combined filter, the gas entering the detection box 300 is filtered in multiple stages, effectively removing impurities from the gas, improving the service life of the equipment, reducing the impact of impurities in the gas on the detection results, and improving the accuracy of gas detection; by setting up detection components, PM2.5 sensors 320, sulfur dioxide sensors 380, and nitrogen oxide sensors 390 are installed in multiple detection boxes 300, thereby facilitating the detection of multiple harmful substances in the gas at one time, improving the practicality of the equipment and the convenience of operation.

[0021] Example 2: As Figure 1 and Figure 2 Vent holes 110 are evenly provided on the inner wall of the bottom end of the housing 100, and handles 130 are fixedly installed on the outer wall of the top of the housing 100.

[0022] The specific application scenario of this embodiment is as follows: when it is necessary to move the air pollution monitoring sampling device between different monitoring points, the staff can easily carry the device by holding the handle 130. The vent 110 is there to balance the air pressure inside and outside the shell during the operation of the device, to avoid abnormal air pressure inside the shell due to the operation of the air pump 360, and at the same time, it can also discharge any small amount of moisture that may exist inside the shell, ensuring the normal operation of the air pump 360 inside the device.

[0023] Example 3: As Figures 3-6 The air intake grille 200 is fixedly installed on the top outer wall of the housing 100. The top of the air intake grille 200 is threadedly connected to the grille mesh 210 via a nut 211. A filter is inserted and sealed into the inner wall of the bottom end of the air intake grille 200. The filter includes filter element boxes 220, of which three are provided. The top of the filter element box 220 is provided with an air inlet 221, and a sealing ring 222 is sleeved on the outer wall of the air inlet 221. The bottom end of the filter element box 220 is provided with an exhaust port 230. The upper and lower filter element boxes 220 are connected by an exhaust port. The inlet 230 is connected to the outlet 221 by insertion. The inner wall of the filter box 220 is fitted with a PM10 pre-filter, an activated carbon adsorption layer and a HEPA filter. The PM10 pre-filter, activated carbon adsorption layer and HEPA filter are installed in the upper and lower filter boxes 220 in sequence. The detection box 300 is provided with several of them. The top of the detection box 300 is provided with a second air inlet 310. The outer wall of the second air inlet 310 is fixedly installed with a second sealing ring 311. The second air inlet 310 is connected to the exhaust port 230 by insertion and sealing.

[0024] The specific application scenario of this embodiment is as follows: to ensure filtration effect and facilitate maintenance and filter replacement, the grille 210 on the air intake grille 200 can prevent larger debris from entering the device, and the grille 210 can be easily removed for cleaning via the nut 211. Three filter cartridges 220 are connected to the air intake 221 via the exhaust port 230, and each filter cartridge 220 contains a PM10 pre-filter, an activated carbon adsorption layer, and a HEPA filter. This modular design allows for individual replacement of a filter cartridge 220 when the filter reaches its service life, without requiring a complete filter replacement. Simultaneously, the detection cartridge 300 is connected to the exhaust port 230 via the second air intake 310 in a sealed plug-in configuration, ensuring that filtered air can smoothly enter the detection cartridge 300 for testing.

[0025] Example 4: Figure 5 and Figure 6 The bottom outer wall of the detection box 300 is threadedly connected to the lower chamber 330. The bottom of the lower chamber 330 is provided with a second exhaust port 331. The upper and lower adjacent detection boxes 300 are connected by the second exhaust port 331 and the second air inlet 310 through the insertion and connection. The detection sensors are fixedly installed on the outer wall of the detection box 300. The detection sensors include a PM2.5 sensor 320, a sulfur dioxide sensor 380, and a nitrogen oxide sensor 390. The detection box 300 is snapped onto the top of the base 120 by a bracket 340.

[0026] The specific application scenario of this embodiment is as follows: Multiple detection boxes 300 are connected by plugging in the second exhaust port 331 and the second air inlet 310. The number of detection boxes 300 can be increased or decreased as needed to meet different monitoring requirements. Detection sensors such as PM2.5 sensor 320, sulfur dioxide sensor 380, and nitrogen oxide sensor 390 can monitor the concentration of corresponding pollutants in the air in real time. The detection boxes 300 are snapped onto the top of the base 120 by the bracket 340, ensuring the stability of the detection boxes 300 and preventing the detection results from being affected by external vibrations and other factors. Through these detection data, the main components and sources of air pollution in the area can be accurately analyzed.

[0027] Example 5: Figure 1 and Figure 5 The bottom outer wall of the exhaust box 350 is fixedly connected to the drain pipe 370, which extends through the housing 100 to the outside. The outer wall of the drain pipe 370 is fixedly installed with a valve 371. The air pump 360 is connected to the exhaust box 350 through the exhaust pipe 361, and the outer wall of the exhaust pipe 361 is fixedly installed with a second valve.

[0028] The specific application scenario of this embodiment is as follows: After the air intake device containing water vapor is detected and filtered, the water vapor may condense into water in the exhaust box 350. At this time, opening the valve 371 on the drain pipe 370 can drain the condensed water from the device, avoiding damage to the electrical components and detection sensors inside the device caused by the accumulated water. The second valve on the exhaust pipe 361 can adjust and control the opening degree of the exhaust pipe 361.

[0029] The working principle of this utility model is as follows: When using it, those skilled in the art can move the device to a suitable position by holding the handle 130. By turning on the air pump 360, the air pump 360 draws out the air from the exhaust box 350. Under negative pressure, the gas in the environment passes through the air intake grille 200 and is filtered by the grille mesh 210, the PM10 pre-filter, the activated carbon adsorption layer, and the HEPA filter before entering the detection box 300. The air quality is then detected by the PM2.5 sensor 320, the sulfur dioxide sensor 380, and the nitrogen oxide sensor 390 installed inside the detection box 300.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
