Automatic cleaning system for air cleaner

Abstract

The invention discloses an automatic cleaning system for an air cleaner. The automatic cleaning system is composed of an array type photoelectric sensor, a signal conditioning circuit, a multi-channel analog-to-digital converter, a processor, an input module, a clock module and an automatic filter net cleaning device. The input module is used for inputting a dust threshold into the processor; the clock module is used for inputting a monitoring signal into the processor at a preset point time; the array type photoelectric sensors is installed at a to-be-detected filter net and a dust intensity signal at the filter net is processed by the signal conditioning circuit and the multi-channel analog-to-digital converter successively and the dust intensity signal after conditioning is outputted to the processor; and the processor is used for determining whether the dust intensity signal after conditioning exceeds a set dust threshold value when receiving the dust intensity signal after conditioning and the monitoring signal; and if so, the automatic filter net cleaning device is driven to carry out cleaning. Therefore, automatic filter net cleaning can be realized.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to an automatic cleaning system for air purifiers. Background technique [0002] With the continuous change of global climate and the frequent appearance of various extreme climates, air purifiers have become an indispensable household appliance in people's daily life. However, a large amount of dust, bacteria and mold will accumulate on the filter screen inside the frequently used air purifier, which is not conducive to ventilation and affects the heating or cooling effect, and is not conducive to human health. According to the data from the Chinese Center for Disease Control and Prevention, if the air purifier is seriously polluted, it will cause sub-health and various diseases. But this problem has not attracted enough attention of people, and many people do not have the habit of cleaning the filter screen frequently. [0003] With the improvement of people's living stand...

Problems solved by technology

For users who are not familiar with the structure of the air purifier and those who are not proficient in cleaning the air purifier manually, this task becomes a burden when using the air purifier, or they can only entrust professional personnel to assist in the operation, or Simply ignore the problem that the filter screen after long-term use may pollute the air environment again, and continue to use the air purifier without cleaning it

As we all know, if the air purifier is used every day without regular cleaning, there will still be a lot of bacteria and dust on the filter, which will cause great harm to the human body and shorten the life of the machine
