Wherein, a liquid storage cavity 4 for storing liquid media is defined between the atomizing base 1 and the shell 3. Atomization component 2 is connected with the liquid storage cavity 4 drain to and atomizing seat 1 between be defined with the atomizing chamber, this atomizing chamber is used for heating atomizing medium and outside air mix behind the circular telegram with atomization component 2.
In the present embodiment, the cavity 61 is enclosed by the inner wall of the housing 3 and a part of the outer wall of the atomizing base 1. In other embodiments, the cavity 61 may also be formed inside the atomizing base 1, the atomizing base 1 and the housing 3 are closely sleeved to form an air inlet 63 communicated with the cavity 61, and the top of the atomizing base 1 is provided with a ventilation slot 62 communicated with the liquid storage cavity 4.
Referring to fig. 3 and 4 together, the atomizing base 1 in this embodiment includes a lower base 10 for mechanically and electrically connecting with the battery device, and an upper base 11 embedded on the top of the lower base 10, wherein the upper base 11 is used for carrying the atomizing assembly 2. Casing 3 cup joints on last pedestal 11 and lower pedestal 10, defines out stock solution chamber 4 and the passageway of taking a breath between casing 3 and the last pedestal 11, and the joint cooperation between casing 3 and the lower pedestal 10.
As shown in fig. 2 and 7, in particular, the upper seat 11 includes an outer peripheral surface, the housing 3 includes an inner peripheral surface corresponding to the upper seat 11, the ventilation channel includes a cavity 61 defined by the outer peripheral surface of the upper seat 11 and the inner peripheral surface of the housing 3, at least one ventilation slot 62 formed on the upper seat 11 or the housing 3, and at least one air inlet 63 formed on the housing 3. Wherein, the air exchanging groove 62 is communicated with the liquid storage cavity 4 and the cavity 61, and the air inlet 63 is communicated with the cavity 61 and the outside.
When a user sucks, the air pressure in the atomizing cavity is negative pressure, the air enters the atomizing cavity from the air inlet channel 100, and the control circuit starts the heating sheet to atomize the liquid medium adsorbed in the porous ceramic body. The liquid medium of the porous ceramic body is reduced, and under the action of capillary force, the porous ceramic body sucks oil liquid from the liquid storage cavity 4 and continues to atomize. The liquid medium of stock solution chamber 4 reduces, and the gas space increases, and too big negative pressure appears in stock solution chamber 4 atmospheric pressure, and the air enters into cavity 61 from the air inlet 63 of shell, then gets into stock solution chamber 4 through the groove 62 that breathes in, realizes gas-liquid balance to let the speed of lower liquid and liquid medium by atomizing speed looks adaptation.

Referring to fig. 8a-8c, the liquid stored in the liquid storage chamber 4 entering the cavity 61 through the air exchange groove 62 is absorbed on the top of the inverted V shape due to the capillary force, so as to be stored in the cavity 61. When the user sucks, the liquid in the reservoir chamber 4 is reduced, the air pressure is reduced, and the tobacco tar adsorbed on the top of the inverted V shape flows back into the reservoir chamber 4 from the ventilation groove 62. The inverted V-shaped structure design can prevent the tobacco tar from flowing out of the shell on one hand, and on the other hand, the tobacco tar at the bottom of the cavity 61 can also flow back to the liquid storage cavity 4 along the inverted V-shaped structure. Wherein, a in fig. 8a-8c is the adsorption amount of the tobacco juice adsorbed on the top of the inverted V shape under different conditions, specifically:
