Fresh air purifier

Abstract

A fresh air purifier is composed of a push-pull window, a clamped purifier body, an elastic separation plate, a centrifugal fan, a front filter screen chamber, a rear filter screen chamber, a front combined filter screen, a rear combined filter screen, a manual air door and a control circuit board. According to the fresh air purifier, holes do not need to be punched in a wall, small space is occupied, and airtightness, attractiveness and normal use of the push-pull window are not affected. The vertical distance between an air inlet and an air outlet of the fresh air purifier is large, indoor air flows from bottom to top, the convection range is large, and air purifying efficiency is high. A combined filter screen replacement alarming function is added, and replacement of the filter screens is determined according to prompts of alarming indicator lights. By pushing and pulling the manual air door, indoor air purification convection or outdoor air purification ventilation can be selected. The fresh air purifier is especially suitable for school classrooms, and multiple fresh air purifiers can be mounted in a dispersed mode for multiple windows of a classroom, so that not only is indoor air purified, but also a good outdoor ventilation effect is achieved. Compared with existing fresh air purifiers, the fresh air purifier is low in cost, convenient to mount and dismount and wide in application.

Description

Technical field: [0001] The invention relates to an air purifier, in particular to a fresh air purifier installed on a sliding window and capable of converting and circulating indoor and outdoor air. Background technique: [0002] Due to air pollution in most cities in my country, haze weather is often caused, which seriously endangers people's health. Therefore, there is a great demand for household air purifiers. In recent years, under the conditions of large-scale, high-intensity and high-frequency air pollution, how to maintain air purification in campus buildings, classrooms, playgrounds and other student activity spaces has become a "rescue and disaster relief" for children's breathing health. ". Whether primary and secondary schools can install air purifiers uniformly has become a topic of public concern. Various domestic administrative departments have jointly investigated this issue for more than a year, and there is no proper plan to protect the health problems that m...

Problems solved by technology

The problem is: at present, most of the household air purifier products and technologies that dominate the market work by placing the machine indoors to perform air circulation, filtration, and purification in a closed room, and cannot be replaced indoors or outdoors. Air, under the condition of few people and large room, the products used can meet the needs of use. If the condition of many people and small room, the effect of use is not good, the air we breathe in the room is actually the exhaust gas discharged by the human body, and the It is not the fresh air outside, which causes indoor hypoxia, and it is easy to cause cross-infection of diseases among the crowd. If ordinary household air purifiers are installed in primary and secondary schools, it will cause other health problems

But its shortcoming is: when the indoor air circulates, the air inlet of the air purifier is very close to the air outlet, and because the wind coming out returns to the air inlet, the indoor air can only be circulated in a small range. low efficiency
