Indoor air purification device with self-purification function and purification method

Abstract

The invention relates to an indoor air purification device with the self-purification function and a purification method of the indoor air purification device. The indoor air purification device comprises a purification cavity. The two ends of the purification cavity are provided with a bad air inlet and an air outlet respectively. Filtering layers are arranged in the purification cavity. A primary filtering screen is arranged outside the bad air inlet in a covering mode. A first electric opening and closing mechanism is arranged at the position of the bad air inlet. A filter, a fan and an adjustable negative air ion generator are arranged on the inner side of the first electric opening and closing mechanism. A fresh air inlet pipe is arranged at the top end of the filter. A second electric opening and closing mechanism is arranged at the position of an inlet of the fresh air inlet pipe. The second electric opening and closing mechanism is connected to a control device. The control device is further connected with an air quality detecting device, a timing device, the adjustable negative air ion generator and the first electric opening and closing mechanism. By the adoption of the indoor air purification device with the self-purification function and the purification method, inner self cleaning of the purification device can be achieved, and the negative ion concentration can be automatically adjusted according to the bad air concentration at the installation position.

Description

technical field [0001] The invention relates to an air purification device, in particular to an indoor air purification device and a purification method with self-purification function. Background technique [0002] Existing air purification devices generally have two types: electrostatic type and adsorption type, both of which have a certain effect on purifying the air; but because the existing air purification devices do not have a self-cleaning function for their own purification equipment, it is easy to cause the inside of the purification device to The filter layer of the filter layer is blocked, resulting in no pollution purification effect; the service life of the air purification device is reduced; in addition, the existing air purification device is generally equipped with a negative ion generator inside, due to the space size of the installation place of the air purification device and the pollution Uncertainty of concentration; it will bring some troubles to users...

[0002] Existing air purification devices generally have two types: electrostatic type and adsorption type, both of which have a certain effect on purifying the air; but because the existing air purification devices do not have a self-cleaning function for their own purification equipment, it is easy to cause the inside of the purification device to The filter layer of the filter layer is blocked, resulting in no pollution purification effect; the service life of the air purification device is reduced; in addition, the existing air purification device is generally equipped with a negative ion generator inside, due to the size of the space where the air purification device is installed and the pollution Uncertainty in concentration; it will bring some troubles to users in choosing an air purification device. While purifying the air, an appropriate amount of negative ions can also prevent and treat acute and chronic bronchitis, asthma, high blood pressure, hyperlipidemia, coronary heart disease, and neurasthenia and other diseases; if the concentration of the negative ion generator is too low, the purification effect of the purification device will be relatively poor, and the desired effect cannot be achieved, and once the concentration of negative ions is too high, ozone will also be generated while negative ions are generated. Some negative ions The ozone produced by the product is 5-6 times higher than the normal concentration; when people use negative ion products for a long time, the concentration of ozone in the indoor air will increase, and the content of negative ions in the air will also increase accordingly. A large amount of negative ions and ozone will stimulate the pharynx, nasal cavity and lungs, which may eventually lead to diseases such as pneumonia
