Background technology
Along with the improvement of people's life, the health problem that air pollution is caused by everybody is the most increasingly paid attention to, and finishing pollution also becomes the important polluter of resident living, and air cleaner receives the welcome of more and more people.Air cleaner is that various air pollutants (generally comprising the finishing pollution of PM2.5, pollen, abnormal flavour, formaldehyde etc, antibacterial, anaphylactogen etc.) can be adsorbed, decompose or be converted to one, is effectively improved the product of air cleanliness.But the filter screen of existing air cleaner is all built-in, if filter screen to be changed, then need to take apart by air cleaner, cause and change the loaded down with trivial details of operation.
The Chinese patent of Application No. CN201320394680.0, including air cleaner, described air cleaner has air inlet, gas outlet and is positioned at the air flue within described air cleaner, and described air inlet is through with described gas outlet by the air flue of described air cleaner;Wherein, there are in the air flue of described air cleaner five dismountable filter screens, described filter screen is followed successively by formaldehyde drainage screen, activated charcoal strainer, highly effective air (HEPA) drainage screen, lysozyme drainage screen and humidifying filter screen along described air inlet to direction, described gas outlet, a kind of air cleaner of the detachable strainer of this product, use by dismountable filter screen, make, when air cleaner needs to change filter screen, to extract the most replaceable cleaning of the framework with filter screen.Simultaneously, filtered and the use of humidifying filter screen by formaldehyde drainage screen, activated charcoal strainer, highly effective air (HEPA) drainage screen, lysozyme, effectively air is purified, but this air cleaner is after filtering for a long time, drainage screen has a large amount of dust and stockpiles, such as can use more air filter in the mansion such as office building, some air filters cannot all be detected whether it exists a large amount of dust and block by inspection personnel.
Utility model content
The purpose of this utility model is to provide a kind of air cleaner detecting system, it is possible to detects the drainage screen of the some air cleaners in mansion, checks whether it blocks.
Above-mentioned purpose of the present utility model has the technical scheme that
A kind of air cleaner detecting system, including the sampling unit on warning circuit and multiple drainage screen being configured at air cleaner, the corresponding drainage screen of each sampling unit, also include and the display terminal of sampling unit telecommunication, display terminal is for showing the air current intelligence of each drainage screen, described sampling unit includes base modules, described base modules is used for providing reference voltage, sampling module, including pressure transducer for detecting the pressure difference of drainage screen both sides and providing sampled voltage, comparison module couples with base modules and sampling module, output drive signal after sampled voltage is more than reference voltage, described driving signal drives display terminal to carry out display alarm.
By using technique scheme, the pressure of drainage screen both sides is detected by pressure transducer in real time, the pressure difference having served as filter net jam seriously rear drainage screen both sides becomes big, comparison module output drive signal carries out display alarm to display terminal, it is replaced by staff, makes staff more targeted to the replacing of drainage screen.
This utility model can be further arranged to, described base modules includes the first reference resistance, the second reference resistance and the 3rd reference resistance, described 3rd reference resistance and the second reference resistance series connection ground connection, the node of described second reference resistance and the first reference resistance couples the input of described comparison module.
By using technique scheme, the first reference resistance, the second reference resistance and the 3rd reference resistance carry out dividing potential drop, provide reference voltage for comparison module.
This utility model can be further arranged to, and described 3rd reference resistance is adjustable resistance.
By using technique scheme, by changing the resistance of the 3rd reference resistance, regulate its dividing potential drop, and then reach to regulate the purpose of reference voltage.
This utility model can be further arranged to: described warning circuit also includes encoder, single-chip microcomputer, and described encoder receives the driving signal of Mei Wei resident family to carry out encoding and transmitting to single-chip microcomputer, is shown to display terminal by single-chip microcomputer.
By using technique scheme, comparison module will drive signal to transmit to encoder, and encoder is by code transfer to single-chip microcomputer, and single-chip microcomputer transmits a signal to display terminal and shows.
This utility model can be further arranged to: described display terminal is computer, and described single-chip microcomputer transmits a signal to computer by wired form.
By using technique scheme, transmit by the way of wired to computer, relatively stable and display convenience.
This utility model can be further arranged to: described display terminal is mobile phone, and described single-chip microcomputer transmits a signal to mobile phone by wireless form.
By using technique scheme, display terminal is mobile phone, wirelessly can supervise the air current intelligence of drainage screen anywhere, it is achieved monitor in real time.
In sum, this utility model has the advantages that
nullThe pressure of drainage screen both sides is detected by pressure transducer in real time,The pressure difference having served as filter net jam seriously rear drainage screen both sides becomes big,Comparison module output drive signal carries out display alarm to display terminal,It is replaced by staff,Make staff more targeted to the replacing of drainage screen,Warning circuit also includes encoder、Single-chip microcomputer,Described encoder receives the driving signal of Mei Wei resident family to carry out encoding and transmitting to single-chip microcomputer,Shown to display terminal by single-chip microcomputer,Comparison module will drive signal to transmit to encoder,Encoder by code transfer to single-chip microcomputer,Single-chip microcomputer transmits a signal to display terminal and shows,Display terminal is computer,Described single-chip microcomputer transmits a signal to computer by wired form,Transmit to computer by the way of wired,Relatively stable and display facilitates,Described display terminal is mobile phone,Described single-chip microcomputer transmits a signal to mobile phone by wireless form,Display terminal is mobile phone,Wirelessly the air current intelligence of drainage screen can be supervised anywhere,Realize monitoring in real time.
