A kind of ultrasonic humidifier
Technical field
The present invention relates to humidifier technology, more particularly, to a kind of ultrasonic humidifier.
Background technology
Traditional ultrasonic humidifier includes base and water tank, and water tank is connected to the top of base, by the bottom of water tank
Structure control flows into the water in base, so that the water level for ensureing to cover on the transducer produces water smoke when having level altitude.
Therefore, traditional ultrasonic humidifier at least has two aspect defects:One is to need to pull down water tank from base and can just be added
Water, uses inconvenience;Two be atomizing effect depend on it is good fit and the polycrystalline substance of water tank between, atomizing effect needs to be carried
It is high.
Then, industry is constantly studied and improves the structure of humidifier, in the hope of having improved atomization ability, pursues optimal humidification
Effect.CN2013105638692 proposes the ultrasonic humidifier that added water in one kind:Cumulative ring group is set above ultrasonic oscillation head
Part, the upper end of the cumulative ring assemblies is fixedly connected with energy-gathering ring float;The cumulative ring assemblies include that at least two is mutually perpendicular

1. it is elongated after many sleeve pipes socket of cumulative ring assemblies when water level is higher in water tank, cause cumulative ring assemblies
Axial length is more long, and the lower end of cumulative ring assemblies and infinite place or director element, produced when ultrasonic oscillation head works
Ultrasonic energy make water produce vibration, can cause cumulative ring assemblies its lower end portion float swing, so as to cannot ensure to gather
The axial aperture of energy ring assemblies is located exactly at the top of ultrasonic oscillation head, that is, cannot ensure that cumulative ring assemblies can be effective
The energy that ultrasonic oscillation head is produced is guided to the water surface, so as to not have cumulative action.
2., by making the length of cumulative ring assemblies with SEA LEVEL VARIATION, the first purpose is intended to the full extent can be by water
Water in case is consumed by atomization!Even if however, when each sleeve pipe of cumulative ring assemblies is completely overlapped, caliber is maximum most
Lower end sleeve pipe has certain axial height in itself, has minimum axial direction highly corresponding to cumulative ring assemblies, if Water in Water Tanks face
When highly less than the minimum axial direction height of cumulative ring assemblies, even if ultrasonic energy now is gathered into the water surface, but the now water surface
Less than the upper port of cumulative ring assemblies, ultrasonic energy is difficult in the less sleeve pipe of caliber for water concussion to become water smoke, is atomized
Amount is small, causes humidifying effect poor.That is, when water tank water surface elevation less than cumulative ring assemblies minimum axial direction highly
When, now energy-gathering ring is failure, but now still has more water in water tank and cannot be effectively atomized, so as to cause humidification
Device cannot play due humidifying effect.
