Aroma diffuser and humidifier silencer

Abstract

A sound-absorbing cover for an aroma diffuser, characterized in that it includes a cover body and a cover top, the cover body is a conical cylinder with a large upper port and a small lower port, and the upper port is small and The frustum-shaped guide cylinder with a large lower port, the surrounding wall of the frustum-shaped cylinder is provided with a number of slits for the passage of water mist, and the surrounding wall of the frustum-shaped guide cylinder is provided with a number of perforations. There are several fog outlets. Compared with the prior art, the present invention has the advantages of effectively eliminating the noise of water droplets falling from a high place onto the water surface, and at the same time, not reducing the production of fog.

Description

Technical field: [0001] The invention relates to an atomization technology. Background technique: [0002] The existing technology to prevent the water droplets generated after atomization from falling back to the water surface to generate noise is as disclosed in patent 2011203152262. The water mist is guided to the side wall of the trumpet-shaped mist outlet channel through the energy-gathering cover set on the ultrasonic generator , at the same time, blow air into the trumpet-shaped mist outlet channel through the blower, the water droplets in the water mist fall on the side wall of the horn-shaped mist outlet channel and then flow back to the water surface along the side wall, and the fog in the water mist is taken out by the blast The trumpet-shaped mist outlet channel, since the water droplets fall into the side wall of the horn-shaped mist outlet channel and then fall back into the water along the side wall, since it flows back along the side wall of the horn-shaped m...

Problems solved by technology

After the fog is generated, it spreads around in a divergent shape. If there is no constraint, it will radiate from the water surface around the ultrasonic generator as the center. If there is a constraint of the energy-gathering cover mentioned above, part of the fog will be covered by the energy-gathering cover. Moreover, the energy-concentrating cover close to the ultrasonic transmission path will also absorb part of the ultrasonic energy, thereby weakening the energy of the ultrasonic wave on the water, thereby reducing the produced fog. The fog is reduced, even if the blower is used to increase the kinetic energy of the fog flowing out of the horn-shaped fog outlet channel, so as to ensure that the fog overflowing the water can flow out of the horn-shaped fog outlet channel. However, because the blower blows on the water surface, Therefore, it cannot make up for the part of the fog lost by the energy gathering cover
