Background technology
General atomizing piece all adopts and add electrode on piezoelectric ceramic piece, after the energising, potsherd sends ultrasonic wave, and the liquid cavitation that it is surperficial becomes the tiny globule, reach the effect of atomizing, because it must fully contact with water, normally places water, the influence that therefore is subjected to liquid level is bigger, the volume of the globule is also bigger simultaneously, be unfavorable for spreading in air, in the relatively stricter occasion of ask for something, use is restricted.
The content of utility model:
The purpose of this utility model is to avoid the deficiencies in the prior art part, can make the water fog particle volume after the atomizing little and provide a kind of, need not control liquid level simultaneously, has the practical atomising device of good result of use.
The purpose of this utility model reaches by following measure, utilizes the piezoelectric property of piezoelectric ceramic piece, and the vibration of generation drives the vibration of front end metallic membrane, and liquid becomes the small globule by the micropore on the metallic membrane, thereby reaches the effect of atomizing.Miniature atomizing piece is by piezoelectric ceramic piece, and metallic membrane is formed, and connects a metallic membrane at the piezoelectric ceramic piece front end, have micropore (micron order) on the metallic membrane, when adding driving voltage to piezoelectric patches, the vibration of its generation drives the vibration of front end metallic membrane, thereby reaches the effect of atomizing.Practical atomising device is made up of shell and atomizing folder, the atomizing folder is provided with miniature atomizing piece, be fixed with wiring board on the shell, the atomizing folder is connected by lead with wiring board, the atomizing folder is connected on the shell by axle, the atomizing folder can sway, be provided with a siphunculus in the enclosure, one end of siphunculus in the enclosure, the other end of siphunculus touches with the atomizing clamping connection and is connected, metallic membrane contact on the atomizing folder leans against on the other end of siphunculus, is provided with the suction cotton core in siphunculus, when adding driving voltage to piezoelectric patches, the vibration of its generation drives the vibration of front end metallic membrane, suction cotton core under metallic membrane can make the liquid on the cotton core become the small globule by the micropore on the diaphragm, thereby reach the effect of atomizing owing to the metal vibration of membrane.Can make the water fog particle volume after the atomizing little, water liquid need not be controlled liquid level by the cotton core transmission simultaneously, has the result of use that arrives very much.
The atomizing folder adopts turning cylinder to be connected on the shell, can rotate flexibly, utilize its gravity simultaneously, make the miniature atomizing piece metal film contact cotton core in the atomizing folder, that has avoided causing because of fixing metal diaphragm position influences atomizing effect with the cotton core loose contact, simultaneously can adjust the position automatically according to the height of cotton core, guaranteed in use, the cotton core shift in position that can cause because of other reasons and to cause metallic membrane to contact with cotton core bad not, thus assurance device can use under a vibrational state.
The bearing of atomizing folder and metallic membrane, leave the space all around, can flow back into tank by the space with the globule that guarantees the stop on the metallic membrane, thereby avoid because after the globule accumulation of diaphragm top, influence atomizing effect, the effect that can have a collection to atomize again to water liquid has prolonged nebulisation time.
The utility model is provided with the substrate with certain inclination angle on shell, the through hole that is communicated with the below tank is arranged on the substrate,
Water fog particle volume after the utility model atomizing is little, need not control liquid level simultaneously, is suitable for various occasions and uses.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As accompanying drawing 1, shown in the accompanying drawing 2, atomising device of the present utility model is made up of shell 1 and atomizing folder 2, the atomizing folder is provided with miniature atomizing piece, be fixed with wiring board 3 on the shell, the atomizing folder is connected by lead with wiring board, the atomizing folder is connected on the shell by axle, and the atomizing folder can sway, and is provided with a siphunculus 4 in the enclosure, one end of siphunculus in the enclosure, metallic membrane contact on the atomizing folder leans against on the other end of siphunculus, is provided with the suction cotton core in siphunculus, and the atomizing folder adopts turning cylinder to be connected on the shell, can rotate flexibly, substrate 5 with certain inclination angle is set on shell, the through hole that is communicated with the below tank is arranged on the substrate, siphunculus passes substrate.
As shown in Figure 2, the utility model atomizing folder is provided with miniature atomizing piece, be fixed with wiring board on the shell, the atomizing folder is connected by lead with wiring board, the atomizing folder is connected on the shell by axle, the atomizing folder can sway, miniature atomizing piece is by piezoelectric ceramic piece 6, metallic membrane 7 is formed, and has micropore (micron order) on the metallic membrane, connect a metallic membrane at the piezoelectric ceramic piece front end, the bearing of metallic membrane leaves the space all around, can flow back into tank by the space with the globule that guarantees the stop on the metallic membrane.
