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.

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