Abstract

The invention discloses an air purification device. The air purification device comprises a purification material, an upper barrel body (1), a lower barrel body (2), a tray (3), a pressure sensor, a comparator and an alarm, wherein an external thread is arranged on the outer side face of the lower barrel body (2); the upper barrel body (1) is in bolt joint with the lower barrel body (2); the tray (3) is arranged in the lower barrel body; the pressure sensor and the purification material are arranged on the upper surface of the tray (3); the alarm is arranged at the outer part of the lower barrel body; the comparator is connected to the pressure sensor and is used for comparing sensed pressure with pre-set pressure; the comparator is used for outputting a high electric level for driving the alarm to start under the condition that the sensed pressure is greater than the pre-set pressure. According to the air purification device disclosed by the invention, the problem in the prior art that the air purification device cannot be replaced in time after being used for long time is solved, and replacement is reminded in time when the purification material is used for too long time.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification device. Background technique [0002] Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust and haze removal, harmful decoration residues and peculiar smells, so as to improve living and office conditions and improve physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gas, mold, particulate matter, decoration residue, second-hand smoke, etc. [0003] How to achieve air purification, avoid the problem of poor air purification effect caused by excessive adsorption, and improve purification efficiency. Contents of the invention [0004] The purpose of the present invention is to provide an air purification device, which overcomes the problem that the air purifier in the prior art cannot be replaced in time after a long...
