As shown in Figure 1, the atomising device that the utility model proposes comprises: the water tank 1 that is used for holding atomized liquid (such as water, medicament, pastil etc.), the bottom of this water tank 1 is fixedly installed transducer 2, and the floating atomizing enhancing section of arranging in water tank 1, and the upper surface of atomizing enhancing section changes and is consistent with liquid surface with liquid level in water tank 1.
Water tank 1 can or have the container etc. of upper cover for open-top receptacle, and the liquid in water tank 1 can be directly contacts with the outer air of water tank 1, therefore do not require that water tank 1 has sealing.
This atomizing enhancing section comprises: guide barrel 3, the axial centre of the longitudinal center line of this guide barrel 3 and transducer 2 keep basically identical, guide barrel 3 axially on have columniform through hole, the bottom of this through hole is that inlet 31, top are fog outlet 32; And be fixedly connected with and swim in the buoyancy section 4 of liquid surface in water tank 1 with guide barrel 3; liquid in water tank 1 produces buoyancy to buoyancy section 4 swims in water tank 1 whole atomizing enhancing section; and buoyancy section 4 provides equilibrant force for guide barrel 3; the longitudinal center line of through hole of guide barrel 3 and the longitudinal center line of transducer 2 are consistent; to guarantee that ultrasonic water column that transducer produces can be successfully enters through hole from the inlet 31 of guide barrel 3, produce in through hole after the liquid mist from fog outlet 32 ejections.
Along with liquid in water tank 1 after atomizing and being sent water tank 1, in water tank 1, liquid reduces gradually, thereby the liquid surface position in water tank 1 also constantly descends, and atomizing enhancing section swims in the liquid level that liquid surface follows in water tank 1 automatically always and changes and dynamically change at its relative position in water tank 1.In atomizing enhancing section in motion process, due to the radial diameter of buoyancy section 4 greater than the radial diameter of the limiting section 5 that is arranged on transducer 2 peripheries (wherein, the radial diameter of guide barrel 3 is less than the radial diameter of limiting section 5), thereby limited 5, buoyancy section 4 limits and makes the bottom of guide barrel 3 can't touch transducer 2, can enter through hole from the inlet 31 of guide barrel 3 to guarantee ultrasonic water column.
In order to ensure buoyancy being provided and making as much as possible guide barrel 3 keep balances, therefore buoyancy section 4 needs to produce enough buoyancy.In general, buoyancy section 4 is made less than the material of fluid density in water tank 1 by density, such as cystosepiment.
In conjunction with shown in Figure 2, in general, being shaped as of through hole is cylindrical.In addition, the shape of through hole can also be that the diameter of inlet 31 is large and taper shape or bottom that the diameter of liquid outlet 32 is less are columniform truncated cone for conical top near liquid outlet 32.
