Referring to figures 1 to 4, a first aspect of the present application provides an embodiment of an electronic cigarette ventilation system comprising: an oil bin placing cavity 12 for placing an oil bin 13; the air flue pad 1 is arranged at the bottom of the oil bin placing cavity 12 and is provided with an air vent 2, the air flue pad 1 is sleeved on the atomizing core component 3, wherein a surface height difference exists between the upper hole surface of the air vent 2 and the upper surface of the air flue pad 1, and the air vent 2 is used for circulating air to maintain the air pressure balance of the electronic cigarette; specifically, due to the arrangement of the ventilation holes 2, the internal air pressure of the atomization chamber containing the oil chamber placement chamber 12 can be maintained in balance. In a specific example, the surface height difference between the upper hole surface of the ventilation hole 2 and the upper surface of the airway pad 1 can be determined according to the size of the oil bin 13 and the oil absorption deformation quantity thereof; wherein, the oil absorption cotton 4 can be laid on the upper surface of the oil bin 13, and the function of the oil absorption cotton comprises preventing condensate from flowing back from the cigarette holder 11. In the embodiment of the application, place chamber 12 bottom at the oil depot and set up air flue pad 1 and draught hole 2 thereof, can effectively utilize circulation balanced principle of taking a breath, make the gas in the atomizing storehouse realize the circulation of taking a breath because of two draught holes 2 of flowing through as shown in fig. 1 arrow, even if ensure that the electron cigarette product is under special external environment such as high temperature, low cold or high altitude, also can realize the atmospheric pressure balance of the inside (placing chamber 12 including the oil depot) of atomizing storehouse, thereby avoid taking place the situation of subassembly burst, oil leak or noise, influence product experience such as user's taste. Meanwhile, the surface height difference exists between the upper hole surface of the air vent 2 and the upper surface of the air duct cushion 1, which is beneficial to promoting the circulation, ventilation and circulation of gas and effectively preventing the air duct cushion 1 from being pressed by the oil bin placing cavity 12 to block the air vent 2 under the gravity condition to influence the circulation and circulation of the gas; furthermore, the specific shape of the duct of the ventilation holes 2 can be vertical or bent.

In one specific example, the specific structure in which the surface height difference exists between the upper orifice surface of the ventilation orifice and the upper surface of the airway pad is any one of the following structures:

(1) Invaginated ventilation holes. The air vent 2 sinks inwards along the direction of the lower surface of the air duct cushion 1, and the height difference between the upper hole surface of the air vent and the upper surface of the air duct cushion is the surface height difference; as shown in fig. 2a, one or more inner grooves 15 can be cut on the upper surface of the airway cushion 1, so that the upper hole surfaces of the ventilation holes 2 are distributed in the inner grooves 15 in a recessed manner with a certain surface height difference, thereby achieving the effect of dredging air and balancing air pressure; inner grove 15 extends (straight line or crooked extension all can) to air flue pad 1 both sides, reaches the lateral wall of air flue pad 1, sets up side groove 16 at air flue pad 1 lateral wall, and chamber 12 intercommunication is placed with the oil bin to side groove 16 for the air current passes through. In addition, referring to fig. 3, an air passing groove 14 may be formed at the top of the oil bin 13, so that after the air below the airway pad is transmitted upward through one of the ventilation holes, the air passes through the air passing groove 14 to another ventilation hole and is output back to the lower side of the airway pad, so as to achieve the purpose of reciprocating cyclic ventilation and air pressure balancing, wherein the air passing groove 14 may be disposed right above the ventilation hole, that is, it may be located on the same vertical plane as the inner groove 15 on the upper surface of the airway pad 1. Specifically, the air below the air channel cushion 1 reaches the inner groove 15 of the air channel cushion 1 through the ventilating holes 2, flows from the inner groove 15 to the side groove 16 of the side wall of the air channel cushion 1, reaches the oil bin placing cavity 12, enters the air passing groove 14 from the top of the oil bin placing cavity 12 (also the top of the oil bin 13) and enters the oil bin placing cavity 12 again, reaches the side groove 16, the inner groove 15 and the ventilating holes 2, enters the atomizing bin below the air channel cushion 1, and completes one circle of air circulation; therefore, the circulation is realized, and the air circulation is realized. Under the condition that the oil absorption cotton 4 has gaps, air entering the air passing groove 14 can also enter the oil absorption cotton 4 and flow out of the oil bin placing cavity 12 again, and the purpose of circulation is achieved.
