Filter screen replacement reminder method and system for air filter equipment, and air filter equipment

Abstract

The invention relates to a filtering screen replacement reminding method and system of air filtering equipment and the air filtering equipment. The filtering screen replacement reminding method comprises the following steps: judging whether an equipment end is at an off-line working mode or an online working mode or not; if the equipment end is at the off-line working mode, calculating the servicelife of a filtering screen by adopting a countdown manner; reminding a user to replace the filtering screen according to the calculated service life of the filtering screen; if the equipment end is at the online working mode, revising the service life of the filtering screen, which is calculated by the equipment end, through a cloud server side by adopting big data; then reminding the user to replace the filtering screen according to the revised service life. According to the filtering screen replacement reminding method and system, the equipment end adopts a manner combining the off-line working mode and the online working mode so that a user can conveniently select the working mode according to requirements; the residual service life of the filtering screen, which is obtained by the equipment end, is revised by utilizing the residual service life of the filtering screen, which is obtained by the cloud server side, so that the calculation of the service life of the filtering screen can be more real and accurate and the user is reminded to replace the filtering screen in time.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a filter screen replacement reminder method and system for air filter equipment, and air filter equipment. Background technique [0002] With the improvement of people's living standards and the continuous enhancement of environmental protection awareness, the sales of air purification products have increased year by year. Among them, the air filtration equipment can not only purify the indoor air, but also can purify the outdoor fresh air into the room, and at the same time improve the freshness and cleanliness of the indoor air. As the use time increases, the filtration efficiency of the filter screen in the air filter equipment will gradually decrease, so the filter screen of the air filter equipment needs to be replaced regularly. [0003] At present, the filter replacement reminder generally sets the total usage time of the filter, and when the cumulati...

Problems solved by technology

However, due to the different operating conditions, gears, air volume, temperature and humidity of air filtration equipment, the life of the filter screen obtained by the existing method can only be used as a simple reference, and the replacement time of the filter screen cannot be accurately determined.

In fact, the concentration of pollutants varies greatly in different regions and seasons, which leads to great differences in the actual replacement time of the filter screen.

Replacing or cleaning the filter screen too early or too late will affect the normal and reasonable use of the air filter equipment.
