I think there's a huge difference between a nebuliser and a vaporiser. To me it looks like a vaporiser.
Please see below.
Nebulizer
A nebulizer is a small electronic air compressor that takes liquid medication and turns it into a mist which is then sent up a long tube into a face mask. The receiver of the medication inhales the fog-like substance into his lungs.The breathing session, or the time it takes to inhale all of the liquid-to-mist medication, can take upwards of 10 minutes to complete.
Uses of a Nebulizer
The main use of nebulizers is to deliver inhalant medication for respiratory diseases to those too young or too weak to use an inhaler. Small children tend to have a difficult time breathing in deeply when using inhalers, or they breathe at the wrong time and do not get enough medication in their lungs. If you have full lungs and are unable to breathe deeply, a nebulizer helps to deliver the medication in smaller particles than those of an inhaler.
Some other uses for nebulizers are for turning aromatherapy essential oils into a fine mist in order to slowly force the scent into the air, causing the scent to fall down slowly, thus increasing the time in which you can smell the relaxing scent of the oil.

What is a vaporizer?
A vaporizer is a device that heats up dried herbs to a temperature at which they release their active components into an aromatic vapor. In this process the herb is not scorched, burned or combusted, and thus no smoke is generated. Although vapor may appear to resemble smoke, it doesn't contain any of the toxic particles (tar, benzene, toluene, naftalene etc.) which make smoking such a health hazard.
So what exactly does this vapor contain?
Aromatherapy and phyto-inhalation
Plants and trees contain numerous volatile oils, most of which we perceive as pleasing aromas. When we walk through a forest and notice the smell of pine, we are smelling the etheric oils given off by these trees. Or when we walk past a field of lavender, it is the etheric oils in the flowers that enter our nostrils. Many of these oils are not simply pleasing to our senses, but have a measurable effect on our health and well-being as well. Lavender oil, for example, calms the nerves, improves sleep, and was used in Greece, Rome and Persia to disinfect sick rooms.
Throughout history and all around the world the essential oils of eucalyptus, rosemary, chamomile, jasmine, cannabis, lemon balm, rose, sage and thyme have been used in perfumes and incense mixtures for their beneficial effects on the body and mind.
A vaporizer is a device which is used to free the active components of medicinal or recreational herbs so they can be inhaled for immediate effects. Vaporizing is a cleaner, healthier and more efficient alternative to smoking and incensing.
