DRAIN STRUCTURE IN BUTTON AND HUMIDIFIER HAVING THE SAME

摘要

PURPOSE: A drain structure in a button and a humidifier having the same are provided to prevent a circuit board from flooding by preventing water flowing into a housing from flowing to the circuit board using a water collecting unit arranged between the circuit board and a button unit. CONSTITUTION: A drain structure in a button comprises a housing (100), a button unit (200), and a water collecting unit (300). A circuit board (500) is arranged inside of the housing. The button unit is arranged on the top of the circuit board and inputs a signal to the circuit board. The water collecting unit is arranged between the circuit board and the button unit to protect the circuit board and receives water flowing through the gap (110) formed between the button unit and the housing therein.
