Which kind of barrel connector is this one?

I have a Phillips air purifier that has his power barrel connector lose (If I move it to the side it turns on, as soon as I let it, it turns off)

I opened the device and wanted to solder it again because I though that is the problem. And looks like it is, but the barrel connector used there is not one with 2 separated legs - as I initially thought - but the connections are kind of one above the other?

Board Front

Board Back

Joint

I THINK I have to fix the connection between the +24V lane and the connector But I do not want to burn something since I can not find which kind of barrel is that and how is it supposed to be soldered.

Here a GIF of the lose joint https://imgur.com/a/Q3eLvgP

Does anyone knows how can I find the model or which kind of barrel it is and how to solder it?

Thanks!
