Air purifier with fresh air introduced

Abstract

The invention relates to an air purifier with fresh air introduced and belongs to the technical field of air purification. The air purifier is composed of a purifier body, a multi-layer filter screen, a panel, an outdoor air input device, a through-wall air inlet pipeline, an outdoor air preliminary filter screen, a connecting pipeline and the like. The air purifier is characterized in that the connecting pipeline and the outdoor air input device are installed on the lower side of the purifier body, one end of the connecting pipeline is connected with an outdoor air outlet in the lower portion of the purifier body, and the through-wall air inlet pipeline is installed at the other end of the connecting pipeline. The air purifier is simple in structure, convenient to install and low in energy consumption; outdoor air can be filtered preliminarily and then mixed with indoor air, then mixed air is purified through the purifier to be output, so that the amount of indoor fresh air is increased and it is guaranteed that sufficient oxygen is provided for people in the room; the effects of purifying air and enriching oxygen for the room are realized, and the problem of existing indoor air purifiers that the outdoor fresh air introduction function can not be achieved, the amount of carbon dioxide in the room is increased after long-term use, and therefore the health of people in the room is harmed is completely solved.

Description

technical field [0001] The invention relates to a fresh air air purifier, which belongs to the technical field of air purification. Background technique [0002] In recent years, due to pollutants from industrial waste gas, transportation, combustion of living stoves, and ground dust, there have been more and more air pollutants in major cities, and the air quality has become worse and worse. The PM2.5 in the air of many cities is serious Exceeding the standard greatly threatens people's health. In order to ensure the indoor air quality, most people buy an air purifier and place it indoors. After absorbing the air in the room through the air purifier, it is purified by the filter element in the machine, and then the purified air is sent out. However, the air purifiers currently on the market only repeatedly draw in, purify, and then send out the indoor air, which belongs to indoor air circulation and purification. When there is no fresh air for a long time, it is easy to c...

Problems solved by technology

[0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art, to provide a device with simple structure, convenient installation, low energy consumption, which can input the outdoor air into the room after preliminary filtration, and mix it with the indoor air and then purify it and output it through a purifier. , to increase the input of indoor fresh air to ensure the oxygen needs of the human body; to solve the problem that the existing indoor air purifier does not have the function of introducing outdoor fresh air, and if it is used for a long time, it will easily cause insufficient indoor fresh air and increase carbon dioxide, which is not conducive to the health of indoor personnel. fresh air air purifier
