Air filtering and refreshing device

Abstract

The invention discloses an air filtering and refreshing device. The air filtering and refreshing device comprises a casing; an air inlet cavity is formed in the casing; an air suction cavity is formedin the left end wall of the air inlet cavity; an air treatment cavity is formed in the left end wall of the air suction cavity; two intermediate cavities are formed in the left end wall and the rightend wall of the air treatment cavity; extruding cavities are formed in the rear end walls of the intermediate cavities; control cavities are formed in the rear end walls of the extruding cavities; aliquid storage cavity is formed in the end wall of a part between the two extruding cavities; two blocking cavities symmetrical with respect to the position of the liquid storage cavity are formed inthe lower end wall of the liquid storage cavity; the lower end wall of the liquid storage cavity is internally provided with two moving cavities symmetrical with the respect to the position of the liquid storage cavity; an exhaust fan is arranged in the air suction cavity; the exhaust fan can suck outside air into the air treatment cavity; the air suction cavity is internally provided with an airfilter sheet; the air filter sheet can filter air; push plates are slidably connected into the extruding cavities; and the push plates can extrude an air freshener into the intermediate cavities.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air filter freshening device. Background technique [0002] At present, the harm of air pollution (PM2.5) to human health has been paid more and more attention by more and more people, and the use of air filtration and purification devices is becoming more and more widely. At present, common air filtration devices generally use filter elements or filter screens step by step The way of filtering is to use the wind generated by the fan to make the pollutants adsorb on the filter net. In addition, it is necessary to replace the filter element and other consumables after a period of use. However, the current air filter is troublesome to replace the filter and the workload is relatively large. And it can only filter and sterilize the air, and cannot provide air freshening function. Contents of the invention [0003] The object of the present invention is to provide an a...
