Project Designing
Initial Designing
* This is the first part of the prototype part and it will act as head or top piece , it has 100 mm diameter and 70 mm length
* All other modules ranging from C2-C6 are made copy of this part here you can see that it has both male and female part
* It is an 12v DC fan which will be used to create suction and able to suck the impure air
This image represents Filter housing ,its just only for show
Initially it was planned that it will incorporate 4 filters and they are as follow
G1 Filter: this will be the first filter and it will be able to to clean air upto 30% and will deal upto air particle of 10 micron size
F1 Filter: this will be the 2 filter in the path of air and it will be able to clean air upto 70% and can deal with particle upto 2 micron
WF1 Filter: this will be the 3rd filter in the series and will purify air upto 80% and will be used to deal with the air pollutent of 1 micron
High efficiency particulate air (HEPA), originally called high-efficiency particulate absorber but also sometimes called high-efficiency particulate arresting or high-efficiency particulate arrestance, is
a type of air filter. Filters meeting the HEPA standard have many applications, including use in clean rooms for IC fabrication, medical facilities, automobiles, aircraft and homes. The filter must satisfy certain
standards of efficiency such as those set by the United States Department of Energy (DOE).
Varying standards define what qualifies as a HEPA filter. The two most common standards require that an air filter must remove (from the air that passes through) 99.95% (European Standard) or 99.97% (ASME
standard) of particles that have a size greater than or equal to 0.3 μm
Through this image you can see that how they will be interlinked to each other
* This is an full detailed image of all the parts associated with the air purifier
Intermediate Design
Through this image you can see that i have made some mpdification in the design by making it more asthetic as well as i added little slots in geometry so i can connect them easily
Same goes for this interconnection module as well
I also made the electronics box and screen mounting
How its look i added some colour to it so it can look more presentable as a CAD design
Final Designing
If you like to know more about the final design please click on this link it will guide you to muc Computer aided design page where i have in detailed mention how and why i have designed the pieces
After I printed the parts i saw this that the size and printing time for 1 piece was too much and i require 4-5 pieces so , i reduces the length of the module
The filter module an electronic box is required to fit on each other so they have this kind of geometry
This will be my electronix box it has a rough size of 100mm length and 140 mm of breadth and it should house my pcb , my ppm sensor , my dht sensor and my tft screen
This will be its opening cover which will be attached to the place using screw's as if something goes wrong i can
This was a sort of clamp which i made to clamp my ppm sensor to the place so when integerate all the systems it wont move
This was the mount which i made to mount the pcb and place it int he electronics box
I am attaching all the CAD Files here if you want you can download these files
