First embodiment

Referring to fig. 1 and 2, the present utility model provides an aerosol-generating device 100, the aerosol-generating device 100 comprising a housing 1, a first heating member 2, a second heating member 3, a first energy storage member 4 and an air intake member 6. Wherein the housing 1 provides an installation space for other components, the first heating element 2 and the second heating element 3 are located in the housing 1, and the first heating element 2 and the second heating element 3 are used for heating the liquid matrix to generate aerosol. The first energy storage element 4 is arranged in the shell 1, and the first energy storage element 4 is used for providing electric energy for the first heating element 2 and the second heating element 3. An air inlet member 6 is provided in the housing 1, the air inlet member 6 being adapted to provide external air into the interior of the nebulization chamber 113 and to direct the air through the vicinity of the first heating member 2 and the second heating member 3 so as to carry the aerosol.

For convenience of description, the width direction of the aerosol-generating device 100 will be represented by the X-axis in each drawing, the thickness direction of the aerosol-generating device 100 will be represented by the Y-axis in each drawing, and the length direction of the aerosol-generating device 100 will be represented by the Z-axis in each drawing. Generally, the aerosol-generating device 100 has a dimension along its length that is greater than a dimension along its width that is greater than a dimension along its thickness.

Referring to fig. 2, a portion of the housing 1 is configured as a liquid storage portion 11, and at least a portion of a liquid storage chamber 111, a main air passage 112, and an atomizing chamber 113 are defined inside the liquid storage portion 11. The nebulizing chamber 113 is used to store a liquid matrix including, but not limited to, tobacco tar. Along the length direction, the atomizing chamber 113 is located below the liquid storage chamber 111, and the atomizing chamber 113 provides a space for releasing aerosol for atomizing the liquid substrate by the first heating member 2 and the second heating member 3. The main air passage 112 extends substantially in the longitudinal direction, one end of the main air passage 112 communicates with the atomizing chamber 113, and the other end of the main air passage 112 communicates with the outside. The main air passage 112 penetrates through the liquid storage cavity 111, that is, the main air passage 112 is surrounded by the liquid storage cavity 111, it is understood that the liquid storage cavity 111 is cylindrical, and the hollow part of the liquid storage cavity 111 is the main air passage 112.
