Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] The atomization process can be the process of heating the electrode to vaporize the liquid in the cavity. Generally, after applying voltage to the electrode to heat it, it does not monitor whether the liquid in the cavity is vaporized. The electrode starts to heat but the liquid does not exist, which not only affects the use effect , and it is easy to cause overheating or dry burning of the electrodes, resulting in damage to the heating components.

[0019] In view of the above problems, in an embodiment of an atomization method provided by the present invention, after a voltage is applied to the electrode, the capacitance or thermal response time of the electrode i...

Abstract

The invention provides an atomization method and an atomizer. The atomizer comprises a casing, an electrode, a cavity and a control circuit, wherein the electrode heats the cavity through an electrothermal effect after voltage is applied to the electrode by the control circuit; the control circuit measures impedance spectroscopy or thermal response time of the electrode in real time and judges whether an atomizing substance exists in the cavity. According to the atomization method and the atomizer, functions of integrated heating and monitoring for presence of the atomizing substance are completely realized by the electrode, the structure is simple, the atomizer is produced based on the MEMS process, is microminiaturized and has small size, and temperature can be increased rapidly.

Description

technical field [0001] The invention relates to the field of atomization, and more specifically, to an atomization method and an atomizer. Background technique [0002] Nebulizers have a wide range of applications, such as air humidification, medical upper respiratory tract therapy equipment, electronic cigarettes, etc. [0003] In the prior art, there is no real-time monitoring scheme for the presence or absence of the atomized substance in the atomizer, which not only affects the user experience effect, but also, after the heating component of the atomizer is powered on, if the atomized substance does not exist, it is easy to Overheating or dry burning of the electrodes occurs, resulting in damage to the heating components. Contents of the invention [0004] The present invention provides a method for overcoming the above-mentioned problems or at least partially solving the above-mentioned problems. [0005] According to another aspect of the present invention, a kind ...
