Method and device for accumulating effective use time of filter screen in air purifier

Abstract

The present invention provides a method and device for calculating the effective use time of the filter in the air purifier, wherein the method for calculating the effective use time of the filter in the air purifier includes: S1. Determine the fan in the air purifier according to the cleanliness of the air The current speed, and obtain the cumulative weight ratio corresponding to the current speed; S2, count the continuous use time of the fan when the speed of the fan is the current speed; S3, multiply the continuous use time and the cumulative weight ratio to obtain air purification The effective use time of the filter in the device. Through the above method, the effective use time T of the filter net can be obtained, the filter net can be utilized to the greatest extent, and cost and time resources can be saved. The advantage of this method is that it considers the impact of the fan speed on the service time of the filter screen, reasonably reminds the user to replace the filter screen, and solves many shortcomings mentioned in the prior art.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to a method and device for calculating the effective use time of a filter screen in an air purifier. Background technique [0002] An air purifier generally includes a filter, a fan, a processor, and an air sensor that senses air cleanliness. The working principle of the air purifier is as follows: the sensor senses the air cleanliness and transmits a corresponding signal to the processor of the air purifier; The signal calculates the fan speed that can achieve the best filtering effect, and generates an electric control signal to make the fan generate a corresponding speed; the fan rotates and blows the air in the atmosphere to the filter, and the air is filtered by the filter to send out clean air. new air. Since the faster the fan speed, the more dust per unit area passing through the filter, and the more dust attached to the filter per unit time, so the fast and slow fan speed can ...

AI Technical Summary

Problems solved by technology

[0004] But the method of prior art can not utilize filter screen to the greatest extent, has caused the waste of certain cost resource

As mentioned above, the air cleanliness will affect the speed of the fan. Assuming that the preset service life of the filter is 9 months, the speed of the fan will be faster when the air cleanliness is relatively low. At this time, the filter may It cannot be used for 9 months. For the same reason, the speed of the fan will be slower when the air cleanliness is relatively high. At this time, the filter may be able to be used for 10 months or even longer, so the existing technology cannot maximize The use of filter nets has caused a certain waste of cost and resources
