Casing of the present utility model is a strip, also can be circle or polygon,
The utility model can use after once adding water for a long time.Length by the lengthening casing or do casing circular or polygon can atomize for a long time for the atomizing piece of a plurality of orderly arrangements, reaches the effect of spatial decoration when realizing the atomizing humidifying performance function.
The utility model is simple in structure, and the water supply of atomizing piece is even, can use for a long time after once adding water, has made things convenient for the use of atomising device, has avoided frequently adding the inconvenience that water brings, and reaches good atomizing effect.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: by tank 7, water inlet 8, sealing device 9, delivery port 10, sealing device 11, micropore vibrating diaphragm 12, piezoelectric energy-conversion sheet 13, seal cover board 14, driver module 15, the lead 16 of casing 1, porous water-absorbing material 2, micropore atomization sheet 3, control module 4, spray switch 5, closed water tank 6, opening.
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the utility model micropore atomization device comprises by casing 1, porous water-absorbing material 2, micropore atomization sheet 3, control module 4 and spray switch 5 and forming.Casing is made up of a closed water tank 6 and open tank 7, be connected by delivery port 10 between closed water tank and the open tank, sealing device 11 is installed on the delivery port, water tank upper has water inlet 8, sealing device 9 is installed on the water inlet 8, porous water-absorbing material is fixed on the bottom of tank, the micropore atomization sheet is made up of micropore vibrating diaphragm 12 and piezoelectric energy-conversion sheet 13, the micropore vibrating diaphragm of micropore atomization sheet is fixed on the porous water-absorbing material top, the micropore vibrating diaphragm tilts to contact with porous water-absorbing material, seal cover board 14 is installed in piezoelectric energy-conversion sheet top, and the water in piezoelectric energy-conversion sheet and the tank is isolated.Driver module 15 is fixed on box house, is connected with spray switch with the micropore atomization sheet by lead 16, and spray switch is positioned at the casing outside.
When operative installations, at first open the casing water inlet, the sealing delivery port, specified altitude assignment is arrived in water filling in water tank then.After water filling was finished, the sealing water inlet was opened delivery port, and the water in the water tank flows into open tank by delivery port.The delivery port height is a little less than the porous water-absorbing material upper surface, when the water surface in the tank was higher than delivery port, air outside can't enter water tank by delivery port again, made that the air pressure in the water tank reduces gradually, form negative pressure, thereby make the water in the water tank stop to flow out.This moment, the water surface in the tank was a little less than the upper surface of porous water-absorbing material, and moisture is transported to the porous water-absorbing material surface by capillarity and contacts with the micropore matrix and be atomized.Water in the tank spreads in air by atomizing, the water surface in the tank is reduced gradually, when the water surface in the tank is lower than the delivery port upper edge at that time, extraneous air can enter water tank by delivery port, thereby make the water in the water tank flow into tank, raise the water surface in the tank, flood delivery port and cut off the passage that extraneous air enters water tank.Water in the water tank is by constantly entering tank with cocycle, continues the effect that supplies water thereby reach.The driver module of micropore atomization sheet is fixed on lower box, is connected with spray switch with the micropore atomization sheet by lead.Spray switch can adopt manually or audio control pattern, and the atomization quantity under audio control pattern can be regulated by acoustic pressure.
As shown in Figure 4, casing of the present utility model extends by cell body, casing is a strip, adopts the structural representation of a plurality of atomizing pieces simultaneously, and the utility model micropore atomization device comprises by casing 1, porous water-absorbing material 2, micropore atomization sheet 3, control module 4 and spray switch 5 and forming.Casing is made up of a closed water tank 6 and open tank 7, is connected by delivery port between the tank of closed water tank and opening, and water tank upper has water inlet 8.
As shown in Figure 5, casing of the present utility model is circular, adopts the structural representation of a plurality of atomizing pieces simultaneously.The utility model micropore atomization device comprises by casing 1, porous water-absorbing material 2, micropore atomization sheet 3, control module 4 and spray switch 5 and forming.Casing is made up of a closed water tank 6 and open tank 7, is connected by delivery port between the tank of closed water tank and opening, and water tank upper has water inlet 8.
The utility model can be made strip, circle or the polygonal micropore atomization device that uses a plurality of micropore atomization sheets simultaneously, reaches the effect of spatial decoration when realizing the atomizing humidifying performance function.
