Problems solved by technology
The general FFU fresh air air purifier installs an air pipe connector directly at the air inlet, which connects to the outside, and purifies the indoor air while purifying the outdoor fresh air, so that the purification efficiency of both is lower than that of working alone. When the time is prolonged, when the outdoor smog is serious, the service life of the filter will be greatly reduced if the outdoor fresh air purification is turned on for a long time, and the outdoor temperature will be brought into the room for a long time, causing indoor temperature loss, human body feels uncomfortable and not energy-saving and environmentally friendly.
Or it has the function of switching between fresh air purification and indoor use alone, but parts need to be replaced or removed, and the operation is cumbersome

Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0023] An FFU fresh air air purifier air duct switching assembly, including an inner support plate 1, a slide plate 2 and an outer support plate 3, the inner support plate, the outer support plate and the slide plate are all rectangular plates, the inner support plate and the outer support plate are similar in area, The width of the slide plate is about half of that of the inner and outer support plates, and the area is greater than the area of the air inlet holes on the left side or the right side of the inner and outer support plates. The inner support plate is fixed on the outside of the primary filter bracket 16, and both are fixed on the outer side of the air inlet of the FFU air cleaner 17 as ...

The invention relates to an air duct switching assembly of a FFU fresh air purifier. The assembly comprises an inner supporting plate, a slide plate and an outer supporting plate, wherein an outdoor air inside air inlet is formed in the left side of the inner supporting plate; an indoor air inside air inlet is formed in the right side of the inner supporting plate; an outdoor air outside air inlethole is formed in the left side of the outer supporting plate; an indoor air outside air inlet is formed in the right side of the outer supporting plate; the slide plate is slidably mounted between the inner supporting plate and the outer supporting plate to shield the indoor air inlet or the outdoor air inlet. The switching assembly can achieve free selection among three modes: outdoor fresh airpurification, indoor air purification and simultaneous purification of indoor and outdoor air by moving the slide plate according to different purification demands.
Description
technical field [0001] The invention belongs to the field of air purification, and relates to an FFU, in particular to an air channel switching assembly for an FFU fresh air purifier. Background technique [0002] In recent years, my country has continued to experience large-scale haze weather mainly composed of PM10 (respirable particulate matter) and PM2.5 (particulate matter that can enter the lungs). The serious trend develops, seriously endangering public health, production and living and traffic safety. [0003] The general air purifiers on the market can only purify the air indoors in a single cycle. When people live in a closed space for a long time, the oxygen content in the indoor air is low, the CO2 content is high, the air is turbid and smelly, and it is easy to cause cerebral hypoxia, followed by symptoms such as dizziness and poor spirits; if the air is not circulated, it is easy to breed Bacteria, especially mold, which is very harmful to human health, can al...
