Air purifier and replacement reminding method and device of filter net of air purifier

Abstract

The invention discloses an air purifier and a replacement reminding method and device of a filter net of the air purifier. Different factors of the air quality are taken into consideration. The concentration of pollutant capable of being adsorbed by the filter net at present is detected, the amount of the pollutant adsorbed by the filter net is calculated, the amount of the pollutant obtained at unit intervals is accumulated, and the total amount of the pollutant adsorbed by the filter net is worked out. The dividing is carried out on the total amount of the pollutant and the maximum adsorption amount, allowed by the filter net, of the pollutant, and the pollutant adsorption surplus ratio of the filter net is obtained. According to the pollutant adsorption surplus ratio, a user is reminded to prepare to replace the filter net with a new filter net in advance, and the problems that according to an existing filter net replacement reminding method, the air quality of the using environment is neglected, and the user cannot be reminded to replace the filter net in advance are effectively solved. According to the method and device, the detected concentration C of the pollutant capable of being adsorbed by the filter net at present is accurate, and the time for reminding of replacement of the filter net is accurate.

Description

technical field [0001] The invention relates to the field of air purification devices, in particular to an air purifier and a filter screen replacement reminder method and device thereof. Background technique [0002] Air purifiers generally consist of filters, fans, processors, and various sensors that measure air quality. During the working process, the purifier controls the fan to drive the air to flow through the filter according to the air quality, and the dust and other pollutants in the air are absorbed by the filter, so as to achieve the purpose of purification. Filters are central to purifying the air, however, over time, pollutants build up in the filter, eventually exceeding its capacity. At this time, the filter screen needs to be replaced in time, otherwise the purification ability of the air purifier will be greatly reduced. In order to avoid excessive use of the filter, a common practice is to accumulate the use time of the filter, and once the use time exce...
