Abstract

The invention discloses an efficiency detecting device of a filter core. The filter core is arranged in an air passage. The efficiency detecting device is characterized by comprising a pressure measuring unit, a computing unit and a comparing unit, wherein the pressure measuring unit is used for collecting pressure data representing the efficiency of the filter core, and the pressure data are generated when airflow passes through the filter core and are associated with the filter core; the computing unit is used for computing according to the pressure data and reference data corresponding to the pressure data and obtaining relative data; the comparing unit is used for comparing the relative data with a specific threshold value corresponding to the relative data and obtaining a comparing result; the comparing result is used for representing the efficiency of the filter core. The invention also discloses an efficiency detecting method of the filter core, and a respirator. By using the efficiency detecting device or the efficiency detecting method of the filter core, disclosed by the invention, concentration information of particulate matters can be quantitatively and more accurately obtained through measuring specific pressure data, so that the filter efficiency of the filter core can be evaluated.

Description

technical field [0001] The invention relates to the technical field of ventilators, and more specifically, to a filter element efficiency detection device, a detection method and a ventilator. Background technique [0002] The impact of indoor air quality on human health has become a worldwide concern. With the gradual improvement of living and working conditions, the urban population spends more time indoors, so indoor air pollution is an important factor that directly affects human health. [0003] When the environment is polluted, there will be a large amount of dust in the air. What people inhale is not pure air but dust when they breathe. These dusts have a serious impact on people's lives and human health. When a person is breathing normally, the respiratory tract can block most particles and foreign objects, but for patients wearing a ventilator, since the gas pressure output by the ventilator is much higher than the normal indoor air pressure, the gas delivered to t...
