Embodiment Construction

[0023] The present invention provides an air purifier and a method for detecting service life of its filter. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Such as figure 1 Shown is the purifier that adopts the filter service life detection method of the present invention, the filter of the purifier includes a gaseous pollutant filter 70 and a solid particle pollutant filter 60 between the air inlet and the air outlet; in addition It also includes a blower arranged at the air outlet, a processor 80, a controller and a display panel 90, and the display panel 90 is connected to the processor 80 by electrical signals. The processor 80 is connected to the controller, and the controller is connected ...

Abstract

The invention provides an air cleaner and a filter service life detection method. The method comprises steps: A, the current gravity value, the current pressure difference, the current pollutant tolerance capacity and the current gas filtration efficiency of the gaseous pollutant filter are calculated; B, if the current gravity value is larger than a threshold, or the current pressure difference is larger than a threshold, or the current pollutant tolerance capacity is larger than a threshold, or the current gas filtration efficiency is smaller than a threshold, a step E is carried out; C, the current gravity value, the current pressure difference, the current dust tolerance capacity and the current particle filtration efficiency of the solid particle filter are calculated; D, if the current gravity value is larger than a threshold, or the current pressure difference is larger than a threshold, or the current dust tolerance capacity is larger than a threshold, or the current particle filtration efficiency is smaller than a threshold, a step E is carried out; and E, a prompt of life expiration is given. The method of the invention can realize real-time and accurate detection on the service life of the filter in the cleaner, the user is timely reminded to change the filter, the cleaning effects are ensured, and a secondary pollution problem caused by untimely filter change is avoided.

Description

technical field [0001] The invention relates to the technical field of purifiers, in particular to an air purifier and a method for detecting the service life of a filter. Background technique [0002] The air purifier controls the air supply mechanism to drive the air to flow through the purification device according to the air quality. The dust, PM2.5, bacteria and other pollutants in the air are absorbed by the purification device, so as to achieve the purpose of purifying the air. The purification device is the core component of the air purifier. However, with the use of the air purifier, pollutants continue to accumulate in the purification device, and eventually exceed the total amount it can hold. At this time, it is necessary to replace or clean the purification device in time, otherwise the purification ability of the air purifier will be greatly reduced, and there may even be a risk of secondary pollution. At present, the detection of the service life of the purif...
