Negative pressure type essential oil atomizer

Abstract

The invention discloses a negative pressure type essential oil atomizer. The negative pressure type essential oil atomizer comprises an essential oil tank, an air inlet pipe and an air pump, wherein the air inlet pipe is inserted into the essential oil tank from the bottom end of the essential oil tank in a sealing manner; the air pump communicates with the air inlet pipe; an air outlet, the porediameter of which is less than the internal diameter of the air inlet pipe, is formed in the top end of the air inlet pipe; a sealing cover is arranged inside the essential oil tank and is used for covering the exterior of the tail end of the air inlet pipe when the air inlet pipe is inserted into the essential oil tank; a slit is formed between the sealing cover and the outer wall surface of thetail end of the air inlet pipe in a clamping manner; an oil inlet communicating with the slit and the inner cavity of the essential oil tank is formed in the sealing cover; an airflow nozzle is fixedly arranged at a part, opposite to the air-out direction of the air outlet, of the top end of the sealing cover; and a mist outlet for emission of atomized essential oil after atomoization is formed inthe top end of the essential oil tank.

Description

technical field [0001] The invention relates to the field of atomizers, more specifically, to a negative-pressure essential oil atomizer. Background technique [0002] Negative pressure atomization is a kind of atomization technology. In the traditional negative pressure atomization technology, the core technology is the same as that of agricultural pesticide sprayers: the lower end of a liquid flow nozzle is inserted into the liquid container to be atomized, and the air flow nozzle is placed at a certain angle. Close to the liquid flow nozzle, after the high-speed air flow jets out of the air flow nozzle, it quickly disperses and forms a negative pressure around the liquid flow nozzle. Misty, complete the atomization process. [0003] However, in the actual use of essential oil atomization, the high-pressure airflow is generally generated by an electric air pump and connected to the airflow nozzle with a pipeline. Since the viscosity of essential oil is much greater than ...

AI Technical Summary

Problems solved by technology

Increased air pressure requires higher cost, and / or larger air pumps

The amount of atomization of essential oils is generally required to be very small. Using a high-cost, large-volume air pump to deal with a small amount of atomization will cause the increase in air pressure, which may cause the amount of atomization to exceed the design expectation, and also increase production and use costs.
