TECHNICAL FIELD
[0001] The utility model relates to the field of ventilator, especially carbon dioxide ventilator. BACKGROUND
[0002] Carbon dioxide ventilator is a device designed to improve air quality in a specific space. In a high concentration of carbon dioxide environment, people may feel fatigue, lack of concentration, dizziness and other symptoms, which will affect people's quality of life and health status. Therefore, the use of carbon dioxide ventilator is crucial to reduce indoor carbon dioxide concentration and improve air quality. Carbon dioxide ventilator usually includes a fan and a carbon dioxide sensor. The carbon dioxide sensor can detect the concentration of indoor carbon dioxide in real time, and automatically or manually start the fan according to the need, to exhaust indoor air and introduce fresh air. The main function of this ventilator is to reduce indoor carbon dioxide concentration and improve air quality, to create a more comfortable and healthy living environment for people.
[0003] In the current practical application, when the gas passes through the carbon dioxide ventilator, the suspended particulate matter contained in the gas may adhere to the fan blade of the ventilator. The accumulation of particulate matter on the fan blade will change the geometry of the fan blade, which will affect the aerodynamic performance of the ventilator. This will lead to a decrease in the efficiency of the ventilator and a decrease in the air volume, which cannot meet the expected ventilation effect. The accumulation of particulate matter on the fan blade will hinder the flow of air, so that the ventilator needs to consume more energy to meet the demand of air flow, thereby increasing the energy consumption. Long-term accumulation of particulate matter on the fan blade may cause vibration and imbalance of the fan blade, increase the blade tip oscillation, which not only reduces the stability of the ventilator, but also may cause fatigue fracture of the fan blade, shortening the service life of the ventilator.
