1. nebulizers use ultrasonic directional pressure to make the liquid surface bulge, and cavitation occurs around the bulging liquid surface. The liquid is atomized into a small molecule aerosol, so that the mist molecules can directly enter the capillaries or alveoli through the aerosol, so as to achieve the purpose of painless, rapid and effective treatment.2. Cleaning: automatic cleaning to prevent clogging, strong, medium and weak atomization intensity, long press the automatic cleaning function is not afraid of residue clogging, resulting in reduced atomization effect.3. capacity: built-in -capacity lithium battery, USB charging mode, built-in high-energy lithium battery, one full charge can be used for about 120 minutes, go out and atomize .4. Mute: super-mute, easy treatment, can be used while resting, does not affect sleep. It is more suitable for use in children's treatment, and the sound is about 40 decibels, which is equivalent to the sound of natural breathing of the human body.5. cold technology is used to punch , atomized hole about 1-3 mMains connection: 100-240V, 50-60Hz, 0.15AInput: 5V/1AAtomized particles: less than 5mMedication flow rate: . 0.2ml/min.Noise: less than 50dB(A)Volume: max. 25mlProduct weight: 100g + 5% (not including accessories)Size:118mm (height), 39.5 mm (diameter)Operating conditions: Temperature: +5C ~ +40CRelative humidity: 15% ~ 93%Storage and transport conditions: temperature: -10C~ +45CColour:white+grayMaterial:ABSPackage Contents:1 x Atomizer1 x Adult Mask1 x Kid Mask1 x Mouthpiece1 x USB Charging Cable1 x Storage BagsOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
