The electrode layer 74 includes a first electrode layer 741 and a second electrode layer 743, and the first electrode layer 741 and the second electrode layer 743 are respectively coated on the outer surfaces of the opposite ends of the substrate 72 in the second direction by means of dip coating or silk screen printing. On the surface, the heating circuit 76 is arranged on the atomizing surface 723, the heating circuit 76 is located between the first electrode layer 741 and the second electrode layer 743, and the two ends of the heating circuit 76 are respectively electrically connected to the first electrode layer 741 and the second electrode The layer 74 and the heating circuit 76 meander and extend on the atomizing surface 732 to cover various areas of the atomizing surface 732 , and the heating circuit 76 is used to atomize the liquid in the matrix 72 .

Since the electrode layer 74 is located at opposite ends of the atomizing surface 723 and there is no need for the atomizing surface 723 to be connected to the power supply, compared with the prior art where the electrical connection points are limited to the atomizing surface, the structural expansion of the atomizing assembly 70 is improved. performance, effectively improving the utilization of the atomizing surface 723, the airflow from the atomizing surface 723 is smooth and unobstructed, has a good atomizing effect, and effectively prevents aerosol condensation.

Specifically, in some embodiments, the base surface includes a first base surface 721 adjacent to the atomization surface 723 and a second base surface 722 opposite to the atomization surface 723 and adjacent to the first base surface 721, the first base surface 721 is arranged vertically or at an obtuse angle to the atomizing surface 723 , the second substrate surface 722 is parallel to the atomizing surface 723 , and the electrode layer 74 partially covers the first substrate surface 721 or partially covers the first substrate surface 721 and the second substrate surface 722 .

As a preferred embodiment, the second base surface 722 faces the first sealed cavity 125 to form a liquid guide surface, and the first electrode layer 741 completely covers the first base surface 721 at one end of the base 72 in the second direction, and along the first electrode layer 741 The two directions extend to the other first base surface 721 and the second base surface 722 adjacent to the first base surface 721 , and the width of the first electrode layer 741 in the second direction is equal everywhere.

Two electrode layers 743, so that the first electrode layer 741 and the second electrode layer 743 are respectively electrically connected to the positive pole and the negative pole of the power supply. In this way, the electrode layer 74 and the electrode member 50 are electrically connected by contacting each other, which simplifies the structure of the atomizer 100 .

The air flow path of the above atomizer 100 is as follows:

The airflow in the external environment first enters the lower base installation cavity 116 from the lower base air inlet 1123, and then flows from the lower base air outlet 1141 into the gap between the lower base 11 and the shell 30, the gap between the upper base 13 and the shell 30, The upper base air inlet 1341 and the second sealed air inlet 1432 enter the atomization chamber, thereby taking away the aerosol generated on the atomization surface 723 of the base 72 of the atomization assembly 70 through the second sealed air outlet 1412 and the upper base. The air outlet 1321 and the third sealed air outlet 152 enter the air outlet channel 32 and finally flow into the external environment.

The flow path of the liquid atomizing medium of the atomizer 100 is as follows:

The liquid atomized medium in the liquid storage chamber 34 enters the first sealed cavity 125 of the first sealed unit 12 through the third sealed liquid inlet hole 154 of the third sealed unit 15 and the upper base liquid inlet hole 1343 of the upper base 13 in sequence, Then it is absorbed by the liquid guide surface of the base body 72 which is connected to the first sealed cavity 125 , and finally reaches the atomizing surface 723 of the base body 72 .

In the atomization assembly 70, atomizer 100 and electronic atomization device, the thimble 50 directly abuts against the electrode layer 74 away from the atomization surface 723 to supply power to the atomization assembly 70, which improves the expandability of the structure and improves the atomization surface 723. The structure utilization and airflow conditions improve the atomization effect. Moreover, since the atomizing surface 723 faces the direction of the air outlet channel 32, the liquid atomizing medium is transferred upwards from the liquid guiding surface 721 and flows out of the atomizer 100 after being atomized on the atomizing surface 723. The aerosol condensation is prevented, and the airflow path design effectively reduces the airflow vortex, further prevents the generation of condensate, and effectively avoids the situation of suction leakage.

To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application, and these all belong to the protection scope of the present application.
