Description

Tubulose humidification element

Affiliated technical field

The utility model relates to a kind of tubulose humidification element, and is relevant with the compound porcelain electrothermal layer of face, face combination electrode, it belong to a kind of energy-efficient, the life-span long, start the novel tubular humidification element fast, that structure is simpler, manufacturing cost is lower.

Background technology

So far, electric moistening device in electric humidification field more than 90% adopts piezoelectric ceramic piece as the humidifier inverting element, and its operation principle is: under the pulse voltage effect, piezoelectric ceramic piece produces the dither of supersonic range, with a large amount of small globules of the shatter formation of water, and then produce vaporific moisture.The major defect of this piezoelectric supersonic humidifier is: the composition of the vaporific moisture of generation (containing a large amount of small globules) is identical with the composition of water in the groove; If water is clean inadequately in the groove, contain microorganism, germ, virus, organic or inorganic toxicant, these harmful substances will (be contained a large amount of small globules), and vaporific moisture takes in the air, and the people can directly jeopardize health after sucking.Therefore, developed country such as Europe, the United States, Japan has formulated strict safety standard to the use of this piezoelectric supersonic humidifier, limit and use injection stage physiological saline, must be before each the use to the tank strict sterilization, therefore the use of this piezoelectric supersonic humidifier is very inconvenient.(piezoelectric supersonic humidifier manufacturer of China and consumer fail fully to pay attention to the problems referred to above, this must cause and pollute room air in humidification, and then harm people's health) in recent years, develop a kind of electric-heating steam humidifier abroad, when using this seam humidifier, even water has pollution in the groove, the steam that is produced also is harmless to the people, this has just thoroughly eliminated the restriction very high to water quality requirement of piezoelectric supersonic humidifier, but because this seam humidifier adopts heating wire as the steam element, this just inevitably exists heating wire component life shorter, it is higher to consume energy, easy scaling, distribute the defective of more idle heat; In addition, this seam humidifier also fails to resolve the technological difficulties (" microcell boiling " is the key technology difficult point in steam humidification field) of " microcell boiling ".
