Intelligent calculating system and method for filtering screen loss of purifier

Abstract

The invention discloses an intelligent calculating system and method for filtering screen loss of a purifier. The intelligent calculating system comprises an environmental monitor, a cloud server andthe purifier, and current air quality information is acquired through the independent environmental monitor and is sent to the cloud server; the cloud server controls the purifier to be adjusted to the matched wind speed level according to the current air quality information, and the air quality information and the matched wind speed information are utilized to calculate the filtering screen lossof the purifier; and when the cumulative filtering screen loss reaches the loss reminding threshold value, the cloud server actively sends a control instruction to the purifier, and finally the purifier receives the control instruction to remind users to replace the filter screen of the purifier. According to the intelligent calculating system and method for filtering screen loss of the purifier,the filtering screen loss is calculated directly by using the scientific method, the calculated filtering screen loss is compared with the cumulative purifying amount, energy is saved, environment isprotected, and maximum utilization of the filtering screen is really achieved; and early or late replacing of the filtering screen is avoided, and the complete demands of safe environment managing ofa user and cost saving are met.

Description

technical field [0001] The invention relates to the technical field of purifiers, in particular to an intelligent calculation system and method for purifier filter screen loss. Background technique [0002] Usually, users of air purifiers will replace the filter screen according to the prompts of the purifier indicator light, and experiments have proved that the filter screen replacement prompts of most purifiers are determined by the length of use, but in actual use, according to the environment, Depending on the time of use and the way of operation, the service life of the filter element of the same purifier is not fixed, so this is an unscientific approach, which will easily lead to waste of effective filters and secondary pollution of invalid filters. At present, there is also a method of estimating the life of the filter screen based on air quality and wind speed. Starting from the time, the waste of the filter screen is reduced to a certain extent, but there are still ...

[0002] Usually, users of air purifiers will replace the filter according to the indicator light of the purifier. Experiments have proved that the filter replacement reminder of most purifiers is determined by the length of use, but in actual use, according to the environment, The service life of the filter element of the same type of purifier is not fixed due to the difference in use time and operation mode, so this is an unscientific approach, which will easily lead to waste of effective filters and secondary pollution of invalid filters

At present, there is also a method of estimating the life of the filter screen based on air quality and wind speed. Starting from the time, the waste of the filter screen is reduced to a certain extent, but there is still a large error
