Ultrasonic humidifier
View Patent ↗An ultrasonic humidifier is disclosed including a chamber, an ultrasonic transducer positioned at the bottom of the chamber, a passage in fluid communication with the chamber, a duct having an inlet and an outlet, the duct being in fluid communication with the passage by way of a passage outlet, a fan positioned in the duct and disposed between the duct inlet and the passage outlet. The fan is configured to propel air through the duct and over the passage outlet such that vapors in the chamber may be drawn into the duct.
1. An ultrasonic humidifier comprising;
a chamber;
a mist generator positioned at the bottom of the chamber;
a tube having a passage in fluid communication with the chamber;
a duct having an inlet and an outlet, the duct being in fluid communication with the passage by way of a passage outlet;
a fan positioned in the duct and disposed between the duct inlet and the passage outlet;
wherein the tube is arranged to extend at an angle to the direction of air flow through the duct, and having the passage outlet formed along the wall of the duct, the angle being acute when measured from the bottom of the chamber to the fan; and
wherein the fan is configured to propel air through the duct and over the passage outlet such that vapors in the chamber may be drawn into the air flow from the duct.
2. The ultrasonic humidifier of claim 1 , wherein the duct is positioned above the chamber.
3. The ultrasonic humidifier of claim 1 , wherein the duct is directed upwardly from the fan.
4. The ultrasonic humidifier of claim 2 , wherein the duct is positioned above the chamber.
5. The ultrasonic humidifier of claim 1 , wherein the mist generator is an ultrasonic transducer.
6. An ultrasonic humidifier comprising;
a chamber;
an ultrasonic transducer positioned at the bottom of the chamber;
a tube having a passage in fluid communication with the chamber;
a duct positioned above the chamber, the duct having an inlet and an outlet, the duct being in fluid communication with the passage by way of a passage outlet;
a fan positioned in the duct and disposed between the duct inlet and the passage outlet;
wherein the tube is arranged to extend at an angle to the direction of air flow through the duct, and having the passage outlet formed along the wall of the duct, the angle being acute when measured from the bottom of the chamber to the fan; and
wherein the fan is configured to propel air through the duct and over the passage outlet such that vapors in the chamber may be drawn into the air flow from the duct and the duct is directed upwardly from the fan.
