Description

Water level control device for humidifier with seesaw structure {WATER LEVEL CONTROL DEVICE FOR HUMIDIFIER WITH SEESAW TYPE}

The present invention relates to a water level control device for a humidifier, and more particularly, to a water level control device for a humidifier with a seesaw structure for adjusting the water level in a humidifier tank through a seesaw motion of a seesaw member.

Humidifiers are divided into ultrasonic, heated, vaporized, and complex types.

All methods have to maintain a constant water level, and the water level is particularly important for ultrasonic humidifiers. This is because if the amount of water is large, the amount of humidification is reduced or the humidification itself does not work. When the water tank was sealed, a valve with a spring was installed on the lid of the water tank, and then the water tank was turned upside down to maintain a certain level. It is a method of controlling the water level by the difference in internal air pressure.

However, recently, simple cleaning humidifiers with an open upper part of the bucket have a problem that water may overflow in the case of a structure with a spring on the lid due to air pressure.

For this reason, a magnet part (or buoy), a part-sensing optical sensor, and a seesaw part are used in the humidifier. In the method using a magnet part, when there is water, the part where the magnet enters rises, and the sensor detects it. The method using the part detection optical sensor is a method of detecting the part by emitting and receiving light when a part made of plastic or the like floats in water. In the case of the method using the seesaw part, there is a fixed axis in the middle like a seesaw, the other side goes down when the part rises, and when the part goes down without water, the opposite side rises to open the lid spring valve of the water container. .

The problem is washing, in that the fixed part methods are difficult or impossible to separate and assemble, so that the part is difficult to clean. For this reason, even if new water is contained, bacterial growth occurs rapidly due to the residue of the part that is difficult to separate.
