Description

Ultrasonic atomizer

Technical field:

the present invention relates to an atomizer.

The background technology is as follows:

the existing technology for preventing the generated water drops from dropping back to the water surface after atomization from generating noise is disclosed in patent 2011203152262, the water mist is guided to the side wall of the horn-shaped mist outlet channel through the energy collecting cover sleeved on the ultrasonic generator, meanwhile, the air is blown into the horn-shaped mist outlet channel through the air blower, the water drops in the water mist drop on the side wall of the horn-shaped mist outlet channel and flow back to the water surface along the side wall, the mist in the water mist is blown out of the horn-shaped mist outlet channel, and the water drops drop in the water return along the side wall of the horn-shaped mist outlet channel and flow back along the side wall of the horn-shaped mist outlet channel, so that the noise generated when the water drops into the water from a high place is avoided. The fog is scattered around in a divergent shape after being generated, if the fog is not restrained, the fog is scattered around the ultrasonic generator on the water surface, if the fog is restrained by the energy gathering cover, part of the fog can not overflow out of the water surface, and the energy gathering cover abutted against the ultrasonic wave transmission path can absorb part of ultrasonic energy, so that the energy of the ultrasonic wave acting on the water is weakened, the generated fog is reduced, and the kinetic energy of the fog flowing out of the horn-shaped fog outlet channel is improved by the blowing of the blower due to the reduction of the fog overflowing the water surface, so that the fog flowing out of the horn-shaped fog outlet channel can be ensured, but the blowing of the blower is acted on the water surface, so that the part of fog which is blocked and lost by the energy gathering cover can not be compensated. In addition, since the air blast needs to enter from the bottom of the horn-shaped mist outlet channel, it is necessary to make the bottom of the horn-shaped mist outlet channel at a certain distance from the water surface so that there is enough space to accommodate the air blast, and the water drops drop from the bottom of the horn-shaped mist outlet channel onto the water surface, even if the distance is not large, the dropping of a large amount of water drops can generate a small sound.

The invention comprises the following steps:

the invention aims to provide an ultrasonic atomizer which can effectively eliminate noise of water drops falling onto the water surface from a high place and can not reduce the production of mist.

The invention is realized by the way, the device comprises a water container, an ultrasonic wave atomizer and a blast system which are positioned in the water container, and is characterized in that a cover with a fog outlet channel at the top is arranged on the water container, the fog outlet channel is in an inverted funnel shape, a bell jar-shaped object positioned right above the ultrasonic wave atomizer is connected to the bottom end inlet of the fog outlet channel, the lower port of the bell jar-shaped object penetrates into the water surface and faces the ultrasonic wave atomizer, the bell jar-shaped object seals the bottom end opening of the fog outlet channel, the upper part of the bell jar-shaped object is positioned in the fog outlet channel, a plurality of fog guide holes are arranged on the periphery of the upper part of the bell jar-shaped object to communicate the interior of the bell jar-shaped object with the fog outlet channel, the tiny channel at the upper part of the fog outlet channel faces the top cambered surface of the bell jar-shaped object and is shielded by the top cambered surface, a plurality of air inlets are arranged on the periphery wall of the lower part of the bell jar-shaped object positioned outside the bottom end inlet of the fog outlet channel, at least the upper part of the air inlet is positioned on the water surface of the water container and faces the ultrasonic wave atomizer, the upper part of the bell jar, the upper part of the bell jar is communicated with the air duct of the blast system.

When the ultrasonic mist generator works to produce water mist, the water mist enters the bell jar, water drops in the water mist are blocked by the top cambered surface of the bell jar and hung on the inner wall of the bell jar to slide back into the water container, even if some water drops pass through the mist guide holes at the upper part of the bell jar, the water drops can be blocked by the side walls of the inverted funnel-shaped mist outlet channel and hung on the side walls of the inverted funnel-shaped mist outlet channel, then enter the inner wall of the bell jar through the mist guide holes and finally slide back into the water container, so that the noise caused by the water drops falling into water from a high position is avoided, and the bell jar with the bottom end opening far larger than the mist generating position of the ultrasonic mist generator is adopted, so that the water mist is effectively covered, the mist in the water mist is not influenced to overflow the water surface, and the normal production of the mist is ensured. Because the bottom port is far larger than the atomizing position of the ultrasonic atomizer and is far away from the ultrasonic transmission path, the energy of the ultrasonic wave acting on water cannot be weakened.

Compared with the prior art, the invention adopts the inverted funnel-shaped mist outlet channel to be matched with the bell-shaped object with the mist guide hole and the air inlet, thereby having the advantages of effectively eliminating the noise of water drops falling onto the water surface from a high place and simultaneously not reducing the production of mist.
