This is really interesting and will be useful but I’m still somewhat confused about the check valve ball Edit: I’ve re watched the video a couple times, is it that the ball prevents the soap from going back down into the tube? And is the pressure applied on the ball by the spring or by the compressed soap
Basically when the nozzle is compressed the fluid pressure forces the ball down to a hard stop on the plastic. (virtually no fluid can go through to reservoir) This means it goes through the nozzle into your hand. When the nozzle is uncompressed the ball has nothing to stop the higher pressure fluid in reservoir from passing. (no hard stop) so the ball lifts and lets the soap go through the check valve.
Mine stopped working after 2 months so I took the top off & it works fine in water, just not soap.. Any suggestions why or how to fix this? It's hot here so it isn't like the soap is too thick.
Try using a stronger spring maybe? I’m assuming it would produce more kinetic energy with a stronger spring so it will be strong enough to push the soap
i will feel smarter next time i wash my hands!
