The following specification particularly describes the invention and the manner in which it is to be performed
BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a steamer and particularly to an automatic medical steamer.
Description of Related Art
[002] Respiratory infections such as cold, cough, and sinus infections are common problems during a winter season. Blood vessels may get inflamed and become irritated due to such respiratory infections. Inflammation in the blood vessels can cause serious problems such as organ damage, aneurysms and alike. Technology has made several advancements in domains which are beneficial for treating the respiratory infections. One such accomplishment includes a medical steamer that has long been used for treating a body owing to the respiratory infections.
[003] Conventionally, a steamer that is available for curing the respiratory infections can be operated manually by a user. The user needs to fill water in a container manually. Also, the user needs to turn on and /off the steamer manually which may be sometimes difficult for the user due to a shortage of time that sometimes results in the user skipping a steam therapy.
[004] Moreover, in another conventional steamer, the medical steamers take about 2-3 minutes to produce the steam after starting a supply of the water to a heater. However, if excessive amount of the water is contained in a water tank, then there can be a chance that the water in the water tank may be discharged from a steam nozzle in a liquid state. Moreover, if the water is still left in the water tank when the power to the heater is turned off, a considerable time interval is required before stopping a spraying action, thereby causing a significant inconvenience to the user as well as some waste in an inhalation liquid.
[005] There is thus a need for an advanced and more effective medical steamer that can administer the drawbacks faced by the conventional approaches.
