Xiaomi expander Soap bubbler breakdown repair

I was using the Xiaomi dispenser soap bubbler well. If I was banging a manual whisk after I got out in the morning, I was born, and why did I make money every day and wake up from this morning?

  

The symptom of the failure is that the bubbles do not come out even if you put your hand over the sensor. Is the battery already discharged? I want to grind it, but I can't.

  

   I think the sensor is malfunctioning. The way to open it is to open the head unit with a flat-blade screwdriver and lift it up as if you laugh.

Check the sensor error. If you touch and release the RX-TX part, the motor works well. No more than a sensor.

The problem was that black part. The sensor was not able to recognize the part because it was swelled during lathering due to long use. Wash it clean.

Reassembly

The damaged front part is finished with bond coating because it does not know how to open it. Handles moisture well.

Now then, should it work?

 

 

It works fine. I saved money. In my opinion, I would like to extend the straw to the bubble nozzle and make it so that the soap bubbles do not get around the sensor as much as possible.
