Open up a Happybrush Sonic V3 /Teardown

ID: 140307

Description: Disclaimer: I took my brush apart because it...

Steps:

1. The bottom plate is held in place by two hooks on opposite sides. I didn't manage to nudge them towards the inside - i destroyed part of the frame and bottom plate during my removal process. The o-ring tore during this. Yet still i pressume it'll do so anyway because there is very little space along the sides. It might need replacing afterwards.
2. On the bottom of the plate you will find the coil for inductive charging with a ferrite(?) core.

3. The bottom plate as well as the rest of the inner parts are kept in place with two hooks each on opposing sides. After you have removed the bottom plate it becomes very easy to move the two remaining hooks.
4. The distance between the bottom and the first dent where the hooks of the bottom plates slide into is about 12mm.
5. I recommend placing the brush upside down on a hard surfcafe to create pressure on the inner parts so they move out after you have released the hooks holding them in place.
6. Note: you need to move the hooks twice. Once from their original resting place and again once they reach the position where the hooks from the bottom plate once were.
7. The indent for the bottom plate is 2.5mm long. The thickness of the frame is 1.5mm along the indent and 1.7mm just after that.

8. This just shows the hooks alongside the sledge holding the parts as well as the rails it slides on inside the frame.

9. I think it might be possible to apply enough pressure on the outside to move the hooks out of their corresponding dents. Once that is done you might be able to push everything out the same way.
