Broken Ventilator Needs Mechanical Support

[Subtitles]

I have a ventilator that got broken. Apparently the plastic material wasn't strong enough.
As this is the best ventilator I have ever used, I don't want to throw it away just yet.
As you can see from the pictures, I need mechanical support and I would appreciate it if any mechanical engineer here can make a suggestion.

I am thinking of using a set of 4 pieces straight bracket alongside the two parts. See link below.
After that use adhesive tape over the brackets so that there is no chance to cut my fingers.

Any better ideas to this?

I would try JB Weld .
Get it along the edges ..
It is slow drying so you will need something to hold the parts stationary as possible.
Like a couple of wood blocks with bolts to work as a clamp while drying.
Remove the clamp & apply a generous layer on the outside of the "crack".

Then a good quality duct tape if possible. Like Gorilla brand.

Thanks for the suggestion Cholla but I don't like to use any kind of epoxies. I will keep this option in mind though.
Besides, this takes more work than using straight brackets. All I need is a drill and a screwdriver.
The difficult part as you say is holding the two parts straight.
I will dismantle the propellers (there are 2) after taking off the front cover and back cover. This way it will be easier to handle the ventilator, as it takes far less space.
I would need to clean the parts anyway if I succeed.

I forgot to put this in.
If you decide to use epoxy.
Get some latex or nitrile gloves.
Much easier than trying to wash it off.

I have a standing fan ( ventilator) but it is only a year old & still in good condition.
My old one the motor failed but it was probably 20 years old.
This is the fan I have:

Only one propeller on my fan.
I do disassemble the cage occasionally & clean the propeller.

Provided pictures are insufficient to advise something useful. Detailed view of broken part will be very helpful.

Thanks again @cholla
I will definitely not use epoxies of any kind.
You really have a nice fan (ventilator) and the price is good.

[Subtitles]

@pandy you are right.
I will take more photos tomorrow after I disassemble the propellers, front and back covers. It will be easier then.

I dismantles all parts, cleaned the motor system and took few images.
The ventilator is of poor design because of the weight of the motors (there are two motors one for the usual work and the second for the up and down movements.
Apparently the plastic was of poor quality and broke the holding mechanism.
Anyway here is the final image. What I want to do is to redesign the holding mechanism between the two parts.
The rod part holds the electronics of the ventilator and the second part is the motor system with the case.
I am back to using brackets. I want to use two 30 cm straight brackets and fix them to the rod using screws and then attach the ends to the motor plastic case.
It should bend easily over the plastic case.
I think two brackets will be strong enough to hold the motor case.
After that use adhesive tape to give it more strength if needed.
What do you think? Any better ideas?
Thank you all for any suggestions.

I vote for epoxy PLUS your brackets/screws.

You probably already checked this.
Ordering new parts from the manufacturer.

Plastic probably was too aged due added optical brightener that makes white whiter than natural. Optical brighteners significantly reduce plastic long term stability. Side to this obviously joint is designed to sustain particular time but not too long - just enough to assure that it will work a while after warranty. Just look at the spring wire diameter and compare to plastic thickness.

I would use some epoxy putty reinforced with metal wires thick enough to create joint - you can shape metal wire to recreate general skeleton and with epoxy putty build around such skeleton joint. Perhaps some carpenter shops may help with commonly available metal joints to connect wooden element. Alternatively you can try to design joint in some CAD and later search for company providing CNC services to turn your design into physical element (there is many options for material - thick plywood, metal, reinforced plastic).
Adhesive tape will not work as glue on tape will eventually flow under constant force.

As I mentioned before, I will never use epoxy of any kind.

There is no point, as there are no parts available for replacement.

Fine for me however this significantly narrows your possible options to revive cheaply your favorite device - you can also try to scan 3D broken parts and try to recreate them in computer and later provide this model to company offering CNC services.

Then live with your substandard repair and don't whine when things fall apart again down the road.

No Problem. I will not whine.
Will see how long my substandard repair will last.
