Description

Electronic cigarette atomizer Technical field

The invention belongs to the technical field of electronic cigarettes, and in particular relates to an electronic cigarette atomizer.

Background technique

At present, an electronic cigarette atomizer that uses a piezoelectric ceramic sheet to atomize smoke oil has a wider operating range because of lower operating power, slower battery loss, and lower smoke temperature. However, the piezoelectric ceramic atomization method also has its own defects, such as the amount of smoke is not adjustable and the amount of smoke is small, and the smoke contains large particles of smoke that affect the taste of the mouth. Therefore, it is necessary to develop a large amount of smoke and good smoke. An electronic cigarette atomizer with low working power and fast atomizing smoke.

In order to solve the above technical problems, the technical solution adopted by the present invention is:

An electronic cigarette atomizer comprising an atomizing core, the atomizing core comprising an atomizing sleeve and a heating wire atomizing structure in the atomizing sleeve, wherein the atomizing sleeve is further provided with a heating wire atomizing structure in parallel The piezoelectric ceramic atomizing structure, the gas path outlet of the heating wire atomizing structure and the gas path outlet of the piezoelectric ceramic atomizing structure are all connected to the nozzle.

The piezoelectric ceramic atomization structure requires low operating power, slow battery loss, low-power batteries, and low smoke temperatures. With the above structure, the piezoelectric ceramic atomization and heating wire are utilized. The atomization combination, when the user needs a large amount of smoke, the heating wire and the piezoelectric ceramic work at the same time, atomizes the smoke oil, and can mix the mists atomized by the two atomization methods, due to the atomization structure of the piezoelectric ceramic atomization The temperature of the smoke is low, so the temperature of the smoke after mixing is low to prevent burns to the user's mouth; when the user needs a small amount of smoke or the battery is low, just select the piezoelectric ceramic work to provide smoke; when the user needs moderate smoke When the user only needs to choose the heating wire to work.

Therefore, the temperature of the oil on the oil storage cotton is higher, the atomization speed is fast, and the oil storage cotton is not easy to foam. In the case that the heating wire does not work, since the smoke oil on the oil storage cotton is not preheated, the flow rate of the smoke oil is slow, and the oil storage cotton is also not easy to foam.
