A central tube 15 is arranged in the shell 10, a first air inlet hole 121 is formed in the bottom of the shell 10, a suction port 14 is formed in the top of the shell 10, and the central tube 15 is communicated with the suction port 14; the mount pad 40 sets up in the inside of casing 10, mount pad 40 and casing 10 sealing connection, and enclose and close and form oil storage storehouse 13, mount pad 40 has seted up fixed orifices 420 and locating hole 415, atomizing subassembly 30 sets up in fixed orifices 420 and with fixed orifices 420 sealing connection, center tube 15 wears to locate in the oil storage storehouse 13 and with locating hole 415 sealing connection, air current passageway 411 and pressure regulating passageway 412 have still been seted up at mount pad 40, pressure regulating passageway 412 sets up in the week side of mount pad 40, air current passageway 411's one end is linked together with first inlet port 121, the other end is linked together with pressure regulating passageway 412 and locating hole 415 respectively, pressure regulating passageway 412 is linked together with oil storage storehouse 13.

The mount pad 40 sets up in the inside of casing 10, through mount pad 40 and casing 10 sealing connection, and mount pad 40 encloses with casing 10 to close and is formed with oil storage storehouse 13, can store the tobacco tar that remains the atomizing in the oil storage storehouse 13.

The atomizing assembly 30 is disposed in the fixing hole 420 of the mounting seat 40 and is connected with the fixing hole 420 in a sealing manner. The tobacco tar stored in the oil storage bin 13 can flow into the atomization component 30, and when the atomization component 30 is communicated with a power supply, the atomization component 30 heats so as to perform atomization treatment on the tobacco tar. The smoke oil is atomized by the atomizing assembly 30 and forms smoke gas, which can be sucked by the user through the central tube 15. Specifically, the positioning hole 415 is formed in the mounting seat 40, the central tube 15 is arranged in the oil storage bin in a penetrating mode and is in sealing connection with the positioning hole 415, when a user performs suction action, external air can enter the shell 10 through the first air inlet hole 121 to be mixed with smoke, and then the mixed smoke and external air enter the central tube 15 through the positioning hole 415 and are sucked through the suction opening by the user.

An air flow channel 411 and a pressure regulating channel 412 are formed in the mounting seat 40, an atomization assembly 30 is also connected in the mounting seat 40 in a sealing manner, and tobacco tar in the oil storage bin 13 can slowly flow to the atomization assembly 30 in the mounting seat 40 and is atomized through the atomization assembly 30 to form smoke. One end of the air flow channel 411 is communicated with the first air inlet hole 121, so that external air can flow into the air flow channel 411 after entering the shell 10 through the first air inlet hole 121, and the other end of the air flow channel 411 is communicated with the pressure regulating channel 412, and the pressure regulating channel 412 is communicated with the oil storage bin 13. Ambient air entering the air flow passage 411 can enter the oil reservoir 13 through the pressure regulating passage 412.

When smoke is sucked by the aerosol generating device 100, tobacco tar in the oil storage bin 13 gradually decreases, and at this time, negative pressure is generated due to the pressure in the oil storage bin 13. After entering the housing 10 through the first air inlet holes 121, the external air flows to the pressure regulating channel 412 through the air flow channel 411 in the mounting seat 40. Because the air pressure state in the oil storage bin 13 is a negative pressure state, the external air in the pressure regulating channel 412 can enter the oil storage bin 13, so that the air pressure in the oil storage bin 13 can be regulated, and the oil storage bin 13 can reach an air pressure balance state. Through such setting, can keep normal atmospheric pressure state in the oil storage storehouse 13 for the tobacco tar in the oil storage storehouse can normally flow to atomizing subassembly 30 and by the atomizing, prevents to lead to the tobacco tar not to flow downwards because the negative pressure of oil storage storehouse 13, leads to the condition of burnt core and dry combustion method to take place after the atomizing subassembly 30 is circular telegram.

In addition, the pressure regulating channel 412 may be disposed laterally on the outer peripheral side of the mounting seat 40, and since the pressure regulating channel 412 is mutually communicated with the air flow channel 411, when the external air enters the housing 10 through the first air inlet 121, the atomized flue gas of the atomizing assembly 30 will mix with the external air, and at this time, some flue gas enters the pressure regulating channel 412 through the air flow channel 411. When the smoke circulates in the pressure-regulating channel 412, the smoke is easy to condense into tobacco tar due to the lower temperature in the pressure-regulating channel 412 compared with the temperature of the atomizing assembly 30. By providing the pressure regulating passage 412 laterally on the outer peripheral side of the mount 40, the condensed tobacco tar can be stored in the pressure regulating passage 412. By such arrangement, after the smoke is condensed into the tobacco tar in the pressure regulating channel 412, the tobacco tar can be stored in the transversely arranged pressure regulating channel 412, so that the phenomenon of backflow in the pressure regulating channel 412 can not occur, and the tobacco tar can not flow outwards.

In some other examples, the air flow channel 411 is also in communication with a pilot hole 415, the pilot hole 415 being in sealed communication with the center tube 15. Specifically, the air flow channel 411 is disposed in the mounting seat 40, the mounting seat 40 is disposed in the housing 10 and is in sealing connection with the housing 10, and the central tube 15 is disposed through the oil storage bin and is in sealing connection with the positioning hole 415 of the mounting seat 40. When the atomization assembly 30 atomizes the tobacco tar into the smoke, the smoke enters the airflow channel 411 and is mixed with the external air, and then the smoke enters the central tube 15 through the positioning hole 415 by the suction action of the smoker, and is sucked from the suction port. Through such setting, can guarantee that the person of sucking is when sucking the flue gas, the atmospheric pressure in the casing 10 can keep balanced for the person of sucking can be comparatively light from the interior suction flue gas of casing 10.

The heating element comprises electrical contacts arranged towards the bottom of the housing 10 and extending outwards out of the housing 10 for connection with a power source for powering the heating element.

The porous ceramic is disposed in the fixing hole 420 of the mounting seat 40, and the porous ceramic is connected with the fixing hole 420 in a sealing manner, so as to prevent the tobacco tar from flowing out through the gap between the porous ceramic and the fixing hole 420. The porous ceramic may have a substantially plate shape or other shapes, and may be in sealing connection with the fixing holes 420. And the second ceramic surface of the porous ceramic can be provided with an oil absorption sheet, when the tobacco tar flows to the second ceramic surface in the through holes of the porous ceramic, the oil absorption sheet can absorb the tobacco tar flowing to the second ceramic surface, so that the phenomenon of outflow of the tobacco tar is prevented.

Regarding the above-mentioned casing 10, the first air inlet hole 121 is provided at the bottom of the casing 10, and the external air can enter the casing 10 through the first air inlet hole 121, so as to ensure the air pressure balance in the casing 10, and prevent the negative pressure from being formed in the casing 10 after the smoke formed after the atomization of the tobacco tar is sucked by the user, so that the subsequent suction is difficult. Specifically, when the user sucks, the smoke and the external air are mixed and then sucked by the user through the air tap 16, at this time, a negative pressure is briefly formed in the housing 10, and at this time, the external air continues to enter the housing 10 through the first air inlet hole 121, so as to balance the air pressure in the housing 10.

The peripheral side of the upper seat 41 is provided with a first ventilation groove 4121, a groove 4122 and an air outlet 4123, and the first opening 4132, the first ventilation groove 4121, the groove 4122 and the air outlet 4123 are communicated in sequence; the first air grooves 4121 are several, and the first air grooves 4121 are mutually communicated and are sequentially and transversely arranged on the outer side wall of the mounting seat 40; the first ventilation groove 4121 is communicated with the switching hole 4112 on one side of the mounting seat 40; the air outlet 4123 communicates with the oil reservoir 13.

The first ventilation groove 4121, the groove 4122 and the air outlet 4123 are in communication with each other in this order, and the seal 43 is provided to cover the first ventilation groove 4121, the groove 4122 and the air outlet 4123 to form the pressure regulating passage 412. When the outside air enters the pressure regulating passage 412 through the air flow passage 411 and the air pressure of the oil reservoir 13 is regulated. The external air first enters the first ventilation groove 4121 through the switching hole 4112, flows in the first ventilation groove 4121 toward the groove 4122, then enters the groove 4122, enters the oil storage bin 13 through the air outlet 4123, and adjusts the air pressure of the oil storage bin 13. By this arrangement, the outside air can enter the pressure regulating passage 412 and air pressure regulating the oil reservoir 13.

The first ventilation groove 4121 and the groove 4122 may be disposed on the circumferential side of the mounting seat 40, and the housing of the mounting seat 40 is matched with the first ventilation groove 4121 and the groove 4122 at this time, so that the first ventilation groove 4121 and the groove 4122 together with the housing of the mounting seat 40 form a channel for ventilation of external air, and the external air can flow in the first ventilation groove 4121 and the groove 4122 without escaping from the pressure regulating channel 412. Alternatively, the first ventilation groove 4121 and the groove 4122 may be provided on the outer peripheral side of the mount 40, and the seal 43 is provided on the mount 40, and the seal 43 is covered in the first ventilation groove 4121 and the groove 4122, so that the first ventilation groove 4121, the groove 4122 and the seal 43 together form a passage through which the outside air circulates.

The first air grooves 4121 are provided with a plurality of first air grooves 4121, and the plurality of first air grooves 4121 are mutually communicated and are sequentially and transversely arranged on the outer side wall of the mounting seat 40. After the external air enters one of the first ventilation slots 4121 through the switching hole 4112, the external air can flow in the plurality of first ventilation slots 4121, and then after flowing to the first ventilation slot 4121 communicated with the groove 4122, the air flows from the first ventilation slot 4121 to the groove 4122, enters the oil storage bin 13 through the air outlet 4123, and then the air pressure in the oil storage bin 13 is regulated. Since the first air channel 4121 is communicated with the air flow channel 411 through the first opening 4132, when the external air enters the housing 10 through the first air inlet 121, the atomized smoke of the atomizing assembly 30 will mix with the external air, and at this time, some smoke enters the first air channel 4121 through the air flow channel 411. When the smoke flows in the first ventilation slots 4121, the smoke is easily condensed into tobacco tar due to the lower temperature in the first ventilation slots 4121 compared with the temperature of the atomizing assembly 30. By providing a plurality of first ventilation grooves 4121 laterally on the outer peripheral side of the mount 40, the condensed tobacco tar can be stored in the laterally provided first ventilation grooves 4121. By such arrangement, after the smoke is condensed into the tobacco tar in the pressure regulating passage 412, the tobacco tar is stored in the first ventilation groove 4121 which is horizontally arranged, so that the phenomenon of backflow in the first ventilation groove 4121 does not occur, and the tobacco tar flows outwards.

Please refer to fig. 4 again. In some embodiments, the airflow channel includes a side hole 4111 and two through holes 4112, the through holes 4112 are two, the two through holes 4112 are respectively formed on two sides of the upper seat 41, and the side hole 4111 is formed at the bottom of the upper seat 41; the first air inlet hole is communicated with the side hole 4111; the side hole 4111 communicates with the positioning hole 415 and the transfer hole 4112; the transfer hole 4112 communicates with the pressure regulating passage 412.

The side holes 4111 are in communication with the first air inlet holes 121, and external air can enter the air flow channel 411 through the side holes 4111 and enter the pressure regulating channel 412 through the switching holes 4112 on both sides. When smoke is sucked by the aerosol generating device 100, tobacco tar in the oil storage bin 13 gradually decreases, and at this time, negative pressure is generated due to the fact that air pressure in the oil storage bin 13 decreases. After the external air enters the housing 10 through the first air inlet holes 121, the external air enters the air flow channel 411 through the side holes 4111, and then the external air enters the pressure regulating channel 412 through the switching holes 4112 at both sides. Because the air pressure state in the oil storage bin 13 is a negative pressure state, the external air in the pressure regulating channel 412 can enter the oil storage bin 13, so that the air pressure in the oil storage bin 13 can be regulated, and the oil storage bin 13 can reach an air pressure balance state.

By providing the two through holes 4112 in the upper seat 41, the two through holes 4112 are respectively located at two sides of the upper seat 41, so that the external air can uniformly enter the pressure regulating channel 412 through the two through holes 4112, and the air imbalance in the pressure regulating channel 412 located at the outer peripheral side of the upper seat 41 is prevented.

After the atomizing assembly 30 atomizes the tobacco tar into smoke, the smoke enters the airflow channel 411 through the side holes 4111 and is mixed with the outside air in the airflow channel 411. Because the side hole 4111 communicates with the air tap 16, the mixture of the smoke and the air can be sucked through the air tap 16 by the sucking action of the user. Through such setting, the person of sucking can mix the back with flue gas and outside air through side hole 4111 and inhale to need not set up in addition and carry out the passageway that communicates with the flue gas, reduced the processing flow of upper seat 41, improved the rate of utilization of side hole 4111. In addition, the external air enters the shell 10 through the first air inlet holes 121, so that when a user sucks the smoke, the air pressure in the shell 10 can be balanced, and the user can easily suck the smoke from the shell 10.

The side hole 4111 is formed at the bottom of the upper seat 41, the fixing hole 420 is also formed at the bottom of the upper seat 41, and the atomizing assembly 30 is connected with the fixing hole 420 in a sealing manner.
