Air purification device can determine filter module failure control method and air purification device

Abstract

The invention relates to a control method to allow an air purifier to judge failure of a filter module and the air purifier. Particularly, the control method includes the steps of detecting, to be specific, detecting noise generated by the air purifier through a noise detection module to obtain a noise value; detecting air quantity at an air supply port through an air quantity detection module toobtain an air quantity; judging failure, to be specific, controlling an air supply module according to the noise value and a first target noise value so that the noise generated by the air purifier ismaintained to the first target noise value, and judging whether the air quantity is less than a first target air quantity; if yes, determining that the filter module loses the filtering function. Whether the filter module fails can be determined according to the noise value and the air quantity so as to remind a user of changing or washing the filter module; controlling is convenient; reminding is accurate.

Description

technical field [0001] The invention relates to the field of air treatment equipment, in particular to a control method for an air purification device that can determine the failure of a filter module and an air purification device. Background technique [0002] At present, the air purification device, as a commonly used purification equipment in every household, will be in a long-term working state in daily life. After a long period of continuous use, the particles in the air will deposit on the consumables, which will cause the resistance of the consumables to increase. After the resistance increases, it will As a result, the air volume of the air purification device becomes smaller, and the effect of cleaning the indoor air cannot be achieved. Moreover, as the use time increases, the user cannot accurately and timely obtain the time when the filter screen fails, and eventually when the air purifier is no longer usable, the user is still using it, and there is no purificat...

[0002] At present, the air purification device, as a commonly used purification equipment in every household, will be in a long-term working state in daily life. After a long period of continuous use, the particles in the air will deposit on the consumables, which will cause the resistance of the consumables to increase. After the resistance increases, it will As a result, the air volume of the air purification device becomes smaller and cannot achieve the effect of clean indoor air

Moreover, as the use time increases, the user cannot accurately and timely obtain the expiration time of the filter screen, which eventually leads to the fact that when the air purifier is no longer usable, the user is still using it and has no purification effect.

In addition, there are some air purifiers that prompt the filter to be replaced, and they are replaced based on the accumulated usage time, without considering other factors, such as the level of environmental pollution, etc.
