Air purification device with conveniently-changeable filter element

Abstract

The invention discloses an air purification device with a conveniently-changeable filter element, comprising a purifier body, a strainer take-up device, a strainer take-up shaft, a strainer pay-off shaft and a gear unit. The strainer take-up device is mounted on one side of the purifier body; the strainer take-up shaft is mounted in the strainer take-up shaft; the gear unit is mounted at the lowerend of the strainer take-up shaft; the strainer pay-off shaft is mounted on the other side of the purifier body. The air purification device is scientific and reasonable in structure, and safe and convenient to use; the strainer take-up device is provided, the strainer take-up shaft is rotated via a motor so as to effectively take up and pay off a strainer, and it is convenient for a user to change the strainer; the strainer pay-off shaft is provided, and therefore, changing a new strainer is facilitated, and a hook at one end is connected with a connection ring on a pull cord so that the strainer is effectively unfolded to carry out filtering; the gear unit is provided, and outer and inner gears are physically engaged such that the strainer take-up device is effectively rotated to take up the strainer; the air purification device is more convenient and quicker to use.

Description
