Indoor supply device of external air

Abstract

The invention provides an indoor supply device of external air (natural wind). The structure of the indoor supply device is as follows: the lower portion of a main body arranged outside a room is detachably provided with a filtering part shell (2); a plurality of filtering parts (3) are detachably arranged in the filtering part shell (2); and an air blower (4) is arranged on the upper portion of the filtering part shell (2). When a power switch (6) is turned on, the air blower (4) works; external air is purified by the filtering parts (3) of the filtering part shell (2), is then sucked in through the air blower (4), passes through a pipeline (7) and an air channel (8) of an outer wall (5) and flows into the room; and therefore, clean air can be kept in the room all the time, and fine dustaccumulating in an indoor window frame and the like is conveyed to the outside. A dust inflow sensing sensor (S) is arranged on the inner side of the outer wall (5), and display is carried out throughan alarm lamp when the inflow of over 0.3 micrometer dust is sensed.

Description

technical field [0001] The present invention relates to an external air (natural wind) indoor supply device, more specifically, a device that purifies external air through a filter unit and supplies it indoors. Indoors, it is used according to the orientation, and the external air of micron and nanometer is purified through the filter part, and when the dust of 0.3 micron or more flows in, it is sensed and displayed by the warning light. Background technique [0002] Generally, air purifiers, negative ion generators, or oxygen generators are used in the indoor settings of apartments or individual houses, but there are problems such as continuous inhalation or exhaust of limited air in the room, and the concentration of indoor oxygen drops sharply. Only the value of carbon Rising, and, the external fine dust enters the room through the gap between the window and the door. [0003] In addition, no matter how long the air purifier is turned on, the amount of dust or carbon dio...

AI Technical Summary

Problems solved by technology

[0002] Generally, air purifiers, negative ion generators, or oxygen generators are used in the indoor settings of apartments or individual houses, but there are problems such as continuous inhalation or exhaust of limited air in the room, and the concentration of indoor oxygen drops sharply. Only the value of carbon rise, and the external fine dust enters the room through the gap between the window and the door

[0003] In addition, no matter how long the air purifier is turned on, the value of dust or carbon dioxide generated at home cannot be reduced, because there is a limit when filtering through the filter.
