Description

Technical Field

[0001] This utility model relates to the field of air quality monitoring technology, specifically to a pump-suction type air quality monitoring device. Background Technology

[0002] There are a number of significant problems with current air quality monitoring technologies.

[0003] First, traditional air quality monitoring devices have low sampling efficiency. Many use natural diffusion or passive sampling methods. Natural diffusion is an extremely slow process, causing air samples to remain in the sensor. The obtained air samples are not representative and cannot reflect real-time changes in the surrounding air quality in a timely and accurate manner.

[0004] Secondly, the detection accuracy of existing air quality monitoring devices is limited. Due to the adsorption of corrosive gases and floating particles in the air, their ability to detect fine particulate matter and low-concentration pollutants is weak, making it difficult to meet the needs of precise air quality monitoring.

[0005] Finally, existing air quality monitoring devices are quite sensitive to environmental conditions (such as wind speed and temperature), and air quality monitoring data are greatly affected by the stability of air samples and temperature, making it impossible to reflect air quality data in a timely and accurate manner.

The sensor module is located inside the gas collection chamber and is signal-connected to the data acquisition module. The data acquisition module is also signal-connected to the digital display module.

[0009] While adopting the above technical solutions, this utility model may also adopt or combine the following technical solutions:

[0014] As a preferred technical solution of this utility model: the device housing is further provided with a 5G Internet of Things cloud module, and the data acquisition module is connected to the 5G Internet of Things cloud module by signal.

[0015] This utility model provides a pump-suction air quality monitoring device, which has the following beneficial effects: by setting an air intake pump on the air intake pipe, the application field of the pump-suction air quality monitoring device is expanded, the automation level of air sampling and the accuracy of data acquisition are improved, ensuring the representativeness of air sampling, the stability of airflow and accurate reflection of real-time changes in surrounding air quality; by setting a microporous filter at the inlet of the air intake pipe, the detection capability of fine particulate matter and low-concentration pollutants is improved, meeting the needs of fine air quality monitoring; and the errors and uncertainties of human operation are reduced, which helps to promptly detect and respond to pollution events and health risks in the environment.

[0018] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, a pump-type air quality monitoring device includes a housing 1. Inside the housing 1, there is a gas collection module 2, a sensor module 3, a data acquisition module 4, and a digital display module 5. The gas collection module 2 includes an inlet pipe 21, an air pump 22, a gas collection chamber 23, and an outlet pipe 24. One end of the air pump 22 is connected to the inlet pipe 21, and the other end of the air pump 22 is connected to the gas collection chamber 23. The outlet pipe 24 is located on the side of the gas collection chamber 23. The sensor module 3 is located inside the gas collection chamber 23. The sensor module 3 is connected to the data acquisition module 4 via signal connection, and the data acquisition module 4 is connected to the digital display module 5 via signal connection.

[0020] A microporous filter 25 is provided at the end of the air inlet pipe 21 away from the suction pump 22 to prevent large particles from entering and to protect the pump from damage.

[0021] The intake pipe 21 is a serpentine pipe, which ensures the airflow stability of the air sample and makes the air sample transmitted to the sensor module 3 more uniform and representative.

[0022] The suction pump 22 is either a micropump or a piston pump. Micropumps are typically small in size and have low power consumption, making them suitable for lightweight and portable applications, while piston pumps can provide higher flow rates and pressures, making them suitable for applications requiring large gas volume sampling.

[0023] Sensor module 3 is equipped with sensors for detecting data such as PM2.5, PM10, CO, NO2, SO2, O3, TVOC, temperature, humidity, and atmospheric pressure, which are used to detect and quantitatively measure the gaseous components in the air.

[0024] Data acquisition module 4 acquires various data collected by the sensor module in real time.

[0025] In this embodiment, sensor module 3 and data acquisition module 4 are selected from the FKT-MK-AQI atmospheric environment detection module from Fosetar Technology. This sensor model adopts a modular product design, has built-in temperature and humidity compensation, and is designed with a temperature and humidity correction system for automatic correction across typical external environments.

[0026] The digital display module 5 is a 10-inch touch screen used to display the monitored air quality data so that users can understand the current air quality situation in real time.

[0027] The device casing 1 also contains a 5G IoT cloud module. The data acquisition module is connected to the 5G IoT cloud module, which quickly transmits the collected data to the cloud to enable remote monitoring and data analysis.

[0028] Specifically, the above-mentioned pump-suction air quality monitoring device is implemented in the following manner:

[0029] When the monitoring device starts working according to the set time, air enters through the microporous filter 25 under the action of the intake pump 22, filtering out large particulate pollutants, floating objects, corrosive gases, etc. in the air. Then, it enters the air collection chamber 23 through the intake pipe 21. After the air passes through the sensor module 3 in the air collection chamber 23 to measure various data, the data is transmitted to the data acquisition module 4. Finally, the air quality data can be viewed through the digital display module 5 and the 5G Internet of Things cloud module. Excess air is discharged through the exhaust pipe 24.

[0030] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
