Knok knok / Door handle

Knok knok
Knok knok

If the olders of the family stay in the bathroom for a long time that will make people outside worry and fear. But it’s embarrassing to ask directly. The timer will be on spiral spring when the loudspeaker locks be rotated, without any power to count down. You just have to set the time of the handle. As soon as the time is closer, it will send out the sound just like someone knock on the door. So that people inside will be response spontaneous without to ask such question. Not only can avoid embarrassing situations but also can prevent accidental undetected.
