[0003] As we all know, the filter in the air purifier has a lifespan. When the life is over, the filter needs to be replaced in time. If the filter is not replaced in time, the air purification effect will be weak due to the accumulation of a large amount of dust in the filter. Moreover, it will increase the burden on the motor in the fan. In severe cases, it will not only fail to purify the air, but will also pollute the air.

[0058] The embodiment of the present application provides a first embodiment of a method for monitoring the life of a filter in an air purifier, including:
[0059] Step 101, in the power-on state, calculate the theoretical wind pressure of the fan according to the specifications of the filter screen and the current particle content in the air.
[0060] It is understandable that the specifications of the filters are different, and the corresponding fan pressures are different under the same air quality.
[0061]In this application, the particulate matter content in the air can be calculated by monitoring the value of pm, for example, pm1, pm2.5, pm10 can be monitored.
[0062] Step 102, determine the current wind pressure weight according to the relative magnitude of the theoretical wind pressure and the actual wind pressure, and the corresponding relationship between the relative magnitude and the wind pressure weight, and the actual wind pressure is acquired by the sensor. ...

[0073] The embodiment of the present application provides a second embodiment of a method for monitoring the life of a filter in an air purifier, including:
[0074] Step 201, in the power-on state, calculate the theoretical wind pressure of the fan according to the specifications of the filter screen and the current particle content in the air.
[0075] In step 202, the current wind pressure weight is determined according to the relative magnitude of the theoretical wind pressure and the actual wind pressure, and the corresponding relationship between the relative magnitude and the wind pressure weight, and the actual wind pressure is acquired by a sensor.
[0076] Step 203: Determine the current air temperature weight and the current humidity weight according to the current air temperature, the current humidity, the corresponding relationship between air temperature and air temperature weight, and the first corresponding relationship between humidity and humidity weight. The ...

Abstract
The embodiment of the present application discloses a method and related device for monitoring the life of a filter in an air purifier, including: calculating the theoretical wind pressure of the fan according to the specifications of the filter and the current particle content in the air when the machine is turned on; The relative size of the wind pressure and the actual wind pressure, and the corresponding relationship between the relative size and the weight of the wind pressure determine the current wind pressure weight; according to the current temperature, the current humidity, the corresponding relationship between the temperature and the temperature weight, and the first corresponding relationship between the humidity and the humidity weight Determine the current air temperature weight and current humidity weight; determine the current life decay speed of the filter according to the preset life decay speed, current wind pressure weight, temperature weight and current humidity weight; determine the current life decay speed of the filter according to the initial life of the filter, the current life decay speed and The length of time it is turned on determines the remaining life of the filter. The application can effectively monitor the service life of the filter screen in the air purifier, so that the user can replace the filter screen in time.
Description
technical field [0001] The present application relates to the technical field of air purifiers, in particular to a method for monitoring the life of a filter in an air purifier and a related device. Background technique [0002] At present, with the improvement of living standards, people's health awareness is getting stronger and stronger. When the air quality is poor, an air purifier is often used to clean the air, whether at home or in the car. [0003] As we all know, the filter in the air purifier has a lifespan. When the life is over, the filter needs to be replaced in time. If the filter is not replaced in time, the air purification effect will be weak due to the accumulation of a large amount of dust in the filter. Moreover, it will increase the burden on the motor in the fan. If it is serious, it will not only fail to purify the air, but will also pollute the air. [0004] Therefore, monitoring the filter screen life becomes an urgent technical problem to be solve...
