Split-type air purifier

Abstract

The invention discloses a split-type air purifier. The split-type air purifier is characterized by comprising an outdoor unit and an indoor unit, wherein the outdoor unit comprises a shell assembly, a filter element assembly, a purification assembly and a power assembly; the filter element assembly is arranged in front of the air inlet of the outdoor unit; a sterilization assembly is arranged in he indoor unit; the outdoor unit is communicated with the indoor unit through a ventilation pipeline, and the outdoor unit is used for exhausting the sucked outdoor air into a room through the indoor unit after passing through the filter element assembly and the purification assembly; the shell assembly of the outdoor unit is divided into an upper box body, a middle box body and a lower box body. The split-type air purifier disclosed by the invention integrates a composite filter element technology, a carbon absorption technology, a photocatalytic degradation technology and an ultraviolet sterilization technology, adopts a novel filter element, and is higher in filter accuracy, better in purification effect, higher in applicability, and wider in application range; with the adoption of an inner and outer air exchange mode, air purity and air quality are improved, and the environmental pollution generated by the running of the equipment is also reduced; the split-type air purifier can be designed according to user needs and an air quantity can be adjusted.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to a split air purifier. Background technique [0002] At present, China's air pollution is extremely serious, especially smog pollution. [0003] Sulfur dioxide, nitrogen oxides, and inhalable particulate matter are the main components of smog. The first two are gaseous pollutants, and the last item, particulate matter, is the culprit that aggravates the pollution of haze weather. They combine with the mist to make the sky instantly gray. The English abbreviation for particulate matter is PM, and what Beijing monitors is PM10, that is, pollutant particles with a diameter less than 10 microns. This particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons. [0004] Common air purification technologies on the market, one is the composite filter paper type, and the other is the electrostatic du...

Problems solved by technology

[0006] Therefore, most of the current air purifiers are indoor air circulation purifiers, which are usually used for indoor air circulation and filtration, such as indoor decoration and indoor air pollution; due to the large amount of dust in the outdoor air and complex gas components, It is not suitable for indoor and outdoor air exchange, so it has basically no practical effect on the current widespread haze

At the same time, due to the proportional relationship between the micron pore size air flow and the pressure difference, the greater the air flow, the greater the pressure difference, and the composite paper filter or filter element has low strength and is easy to break and lose its effect; for electrostatic air purifiers , when the air volume increases, the flow rate will increase, which will also seriously affect the removal efficiency of fine dust

[0007] In addition, most of the current air purifiers are basically aimed at indoor air circulation purification treatment, which has basically no practical effect on the current widespread haze, and because most of the current air purifiers are indoor air circulation purifiers, Therefore, there is still a very serious problem, that is, it cannot solve the phenomenon of oxygen decline produced in the process of indoor air circulation, that is, the phenomenon of hypoxia.

The above-mentioned fundamental reasons are: the limitation of the prior art; the limitation of the material of the existing filter element filter plate; the limitation of the solution ideas and direction
