Abstract

The invention provides a porous heating body, which comprises a porous body; the porous body comprises a first porous part, a second porous part and a third porous part which are sequentially arrangedalong the length direction; and the cross-sectional areas of the first porous part and the third porous part are larger than that of the second porous part along the width direction; the porous bodyis provided with a heating body extending along the length direction, and the heating body is provided with a heating part; at least a part of the extending length of the heat part is overlapped withthe extending length of the second porous part. According to the porous heating body, the porous body is in a dumbbell shape with a small middle part and thick two ends, and the middle part of the porous heating body is relatively provided with a shorter tobacco tar conducting distance, so that the tar conductivity during tobacco tar atomization is improved. The protruding parts at the two ends, on the one hand, can play an oil storage effect to supplement the tobacco tar consumption of the middle part, thereby improving the tobacco tar supplement efficiency during atomization, on the other hand, are convenient for fixing and sealing in connection with other components and at the same time, can reduce the heat to radiate outwards.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic cigarettes, and in particular to a porous heating element, an atomizer containing the porous heating element, and a method for preparing the porous element. Background technique [0002] The core component of the electronic cigarette product is an atomizer that vaporizes the e-liquid. The function of the atomizer is mainly based on a porous body and a heating element. Among them, the porous body is a component with capillary pores inside itself, which can infiltrate, absorb and conduct e-liquid through the internal pores; and the heating element has a heating part for heating and a conductive pin part. It is used to heat and evaporate the e-liquid conducted by the porous body to form an aerosol of e-liquid for smoking. [0003] At present, porous bodies usually include porous fibers, porous ceramics, foamed metals, etc.; these porous bodies with rigid structures usual...
