Air purifier

Abstract

The invention discloses an air purifier. The air purifier comprises a shell with an air inlet and an air outlet; the air purifier further comprises a flowerpot assembly, a microorganism box, an ecological purifying system of a water tank, a filtering system and a control system used for controlling, wherein the flowerpot assembly, the microorganism box, the water tank ecological purifying system, the filtering system and the control system are arranged in sequence; water of the ecological purifying system flows through the filtering system so as to bring dust and VOCs which are absorbed by the filtering system into the ecological purifying system for purification; the flowerpot assembly comprises a flowerpot, water of the water tank enters the flowerpot through a water inlet, and when the water level is higher than a water outlet, the water flows through the microorganism box to enter the water tank so as to form water circulation. The air purifier is simple in structure, easy and convenient to operate and low in cost; the purification efficiency on air pollutant, in particular to the VOCs, is high, the dust and the VOCs are blocked when air flows through the filtering system and are brought into the microorganism box under the effect of the water flow, the VOCs are decomposed and purified through microorganisms, and the dust is brought into the flowerpot assembly under the effect of the water circulation so as to be absorbed and used by roots of plants; the ecological purification technology is used, so that environmental protection is achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purifier. Background technique [0002] The rapid development of urbanization has caused indoor and outdoor air to be polluted by dust and toxic gases to a certain extent. In addition, building materials, furniture, electrical equipment, etc. continue to release a large amount of VOCs (toxic and harmful volatile organic compounds) indoors, making indoor air The quality is worrying, which directly affects people's health and comfortable life. [0003] At present, the purification methods of air purifiers on the market mainly include chemical reaction method, physical adsorption technology, ozone negative ion technology, nano-photocatalysis technology, low-temperature plasma technology, plant purification and biodegradation, etc. Most air purifiers need to be replaced regularly. setup, resulting in expensive maintenance. Most mechanical purifiers can only filter dust in the...

Problems solved by technology

[0003] At present, the purification methods of air purifiers on the market mainly include chemical reaction method, physical adsorption technology, ozone negative ion technology, nano-photocatalysis technology, low-temperature plasma technology, plant purification and biodegradation, etc. Most air purifiers need to be replaced regularly. setup, making it expensive to maintain

Most mechanical purifiers can only filter dust in the air and cannot effectively remove VOCs

Generally, plant air purifiers use the roots, stems, and leaves of plants to absorb and degrade VOCs in the air to purify the air, such as the plant air purifier and its system disclosed in the Chinese patent No. ZL201310214831.4, such In the plant air purifier, the plant body is the core system of air purification. The air purification effect of the plant body itself is limited and not targeted. If other auxiliary air purification methods are not used, the purification effect of the plant air purifier is difficult to reach the ideal level.

The main method of air purification by microbial method is to use the assimilation of widely distributed, vigorously metabolized, and rapidly multiplying microbial populations to degrade VOCs in the air to achieve the purpose of purifying the air. Purifier, but microorganisms are easy to die and need to be replenished frequently, which is troublesome to use and high in cost

[0004] The Chinese patent with the patent number ZL201420592198.2 discloses an indoor air purifier, which is equipped with a biological purification layer and a plant planting position, through which the plant root system is inserted into the water surface of the water tank, so that the plant root system and the microorganisms in the water coexist, and at the same time use The purification effect of plants and microorganisms is ensured, and a complete ecosystem is established, which ensures the growth of plants and the long-term survival of microorganisms, and removes dust and VOCs efficiently. Symbiosis with microorganisms, this structure has a certain limit on the water level, the water level should not be too low, the root system of the plant is located in the water tank, the mud on the root system, the broken or fallen root system in the water tank will affect the water cycle and affect the purification effect
