EXAMPLE III
However, the controller 100 must be always on when the humidifier is operating, and the cost of the humidifier increases the amount of power consumed by the always-on controller 100 and the expensive price of the controller 100, the lower level sensor 90a, and the upper level sensor 90 b.
Referring to fig. 4, 5, 6 and 7, the third embodiment is different from the first embodiment in that,
the device also comprises a side hole 24, an elastic membrane 25, a rotating shaft 26, a rotating rod 27, a floating ball 28, a rotating rod hole 281, an elastic rope 282, a magnet 29, a second contact patch 291, an electric patch fixing rod 110, a first contact patch 120, a first lead c, a second lead d and a third lead e;

However, when the liquid level in the upper housing 20 is between the preset lowest and highest liquid levels, the first contact piece 120 is always in contact with the second contact piece 291.
When the liquid level is raised from the preset lowest height to the preset highest height, the air pump 60 continuously works; however, when the liquid level rises to a preset maximum level, the air pump 60 stops; real-time monitoring of a sensor and control is not needed, and therefore electricity charges are saved.
Further, the axis of the rotating rod hole 281 is perpendicular to the axis of the rotating rod 27 and the rotating shaft 26.

The second inlet pipe 160 communicates with the first inlet pipe 140.
The lower end of the second water inlet pipe 160 is located below the lower sealing plate 150.
The principle is that when the first air pump 60 is inflated, the water in the soft water bucket 52 enters the upper cover 20 through the first water inlet pipe 140 and the second water inlet pipe 160; when the medical staff finds that the soft water bucket 52 is empty of water, the fixing ring 51 can be detached from the upper housing 20 to fill the water; however, since the first water inlet pipe 140 is fixedly provided with the check valve, the water in the upper housing 20 does not flow out, and the humidifier can still work normally when water is filled into the soft water bucket 52.
Secondly, because the lower extreme of second inlet tube 160 is located under the shrouding 150, when the gasbag 70 will soft water bucket 52 bottom lift to contact second inlet tube 160 lower extreme (the soft water bucket 52 bottom will promptly the shutoff of second inlet tube 160 lower extreme), the deposit of small rust, tiny granule grit can not get into in the upper shield shell 20 in the soft water bucket 52, promptly ultrasonic nebulizer 22 can not atomize the moisture that contains small rust, tiny granule sand always.
Further, the lower end of the second water inlet pipe 160 is located 1-3cm below the lower sealing plate 150.
