Description
Technical Field
[0001] The utility model relates to the technical field of environmental detection devices, in particular to a multifunctional micro environmental air quality monitoring device. Background Technique
[0002] In modern society, the destruction of nature by humans has led to a deteriorating outdoor environment, and due to decoration, the indoor environment has also become less and less up to the standard of healthy living. Traditionally, people obtain the local air quality through the local meteorological bureau or through an APP that reads the public data of the meteorological bureau. However, the air quality data provided by the meteorological bureau is limited (temperature, relative humidity, ultraviolet intensity, wind force, etc.), and the meteorological bureau targets the entire city and does not specifically cover a certain community or even accurately reach a certain room in a certain building. In fact, the data given by the meteorological bureau is used to guide people's travel rather than for health.
[0003] A multifunctional air quality monitoring device described in the patent with the patent announcement number CN213398428U includes a housing, which includes an air inlet area, an air outlet area, and several heat dissipation areas; a temperature and humidity sensor arranged opposite to the air inlet area; an air quality sensor arranged opposite to the heat dissipation area; a negative ion sensor arranged opposite to the heat dissipation area; a control board electrically connected to the temperature and humidity sensor, the air quality sensor, and the negative ion sensor respectively; and a buffer pad arranged on the lower side of the housing. Its advantages are that it integrates a temperature and humidity sensor, an air quality sensor, and a negative ion sensor, can obtain a variety of air quality data, and meets the use requirements; by changing the layout of the air inlet area, the air outlet area, and the heat dissipation area, and changing the air flow direction, the air flows through the temperature and humidity sensor, the air quality sensor, and the negative ion sensor in sequence, thereby making each air data more accurate.
[0004] However, this device has deficiencies in use. In order to complete indoor and outdoor monitoring work, this device is built-in with various types of sensors.
