Atomizing core and preparation method thereof, atomizer and electronic atomizing device

Abstract

The invention provides an atomizing core and a preparation method thereof, an atomizer and an electronic atomizing device. The atomizing core comprises a porous base body and a heating body. Wherein the porous substrate is provided with an atomization surface; the heating body is arranged on the atomizing surface of the porous matrix and is used for heating and atomizing the aerosol generating matrix on the porous matrix during electrification; wherein the ratio of the effective atomization area of the porous matrix to the thickness of the porous matrix to the porosity of the porous matrix is 6.4: (0.8-1.2): (0.2-0.3). According to the atomizing core, the overall atomizing efficiency of the atomizing core is greatly improved, and the atomizing amount of the atomizing core is increased; and the phenomena that the aerosol generating matrix is burnt, or peculiar smell is generated, oil is fried and the like can be effectively prevented, and meanwhile the cruising ability of a power source assembly electrically connected with the atomization core is not affected.

Description

technical field [0001] The invention relates to the technical field of electronic atomization, in particular to an atomization core and a preparation method thereof, an atomizer and an electronic atomization device. Background technique [0002] At present, in the field of closed electronic atomization, the film-coated porous ceramic atomizing core is widely used as a heating element to replace the traditional cotton core, so as to heat and atomize the aerosol-generating substrate to form an aerosol. [0003] The existing atomizing cores generally use 6.5W constant power output. Under this output power, the atomization volume of the atomization core is basically between 5.5-6.5mg / puff; if you want to get a larger atomization volume, you can only pass Increase output power. However, increasing the output power may cause the aerosol generating substrate to be burnt, or produce peculiar smell, fried oil, etc., and at the same time, the battery life of the power supply connecte...
