Han Yi 3704 oxygen pump gas regulating switch failure.

First of all, go to the store to apply for maintenance, inspection and debugging. But if people are not responsible, there is nothing they can do. I have to find a way to solve it myself. Just throw it away and buy a new one. Or make do with it. Or change it.

You can take it apart and see the principle of adjusting the size inside. If it is not the principle of resistance, discard it. If there is pressure or resistance, move them to compact and try to compact.

Do I have to use two heads? 1 air outlet? The solutions I can think of are as follows:

Adjust the two sockets to the maximum power, and then connect two shorter air pipes.

Connect two air pipes to the 1 air outlet using a tee.

Then use a 3-way link to modify it twice to 2 air outlets.

Then fine-tune the valve with a cheap air pump and adjust each air outlet separately.

It's done.

P.S. is more troublesome to do so, but it should not impress his ability. If you are afraid of trouble, there is an easier way.

So method two:

Adjust the two sockets to the maximum power, and then connect two shorter air pipes.

Then connect a simple air pump regulating valve to each short pipe.

It's done.

P.S. is too close to the original fuselage, and there is almost no difference with his design, so it may not solve the problem, but the same problem will occur.
