Humidifier AC Adapter Whining Noise

Hi - I have a number of switchbot devices and for the most-part they are good. However the AC adaptor for my humidifier makes a whining noise when plugged in. Similar to maybe a radar sounds?  WeeWooWeeWooWeeWoo at a very high frequency.  

I'd like to replace the adapter....but it seems to be proprietary and they aren't sold on the website.  What can I do? 

 

Thanks
