Referring to fig. 4, the package 2 is provided with a first seal ring 21 and a second seal ring 22 along the circumferential side thereof, and the first seal ring 21 and the second seal ring 22 are arranged at an interval up and down. The first sealing ring 21 and the second sealing ring 22 abut against the inner wall of the oil bin 13 to seal the inner wall of the oil bin 13 and prevent the aerosol matrix of the oil bin 13 from flowing out of the inner wall. It is understood that in other embodiments, the number of the sealing rings may also be three or more, so that the effect of sealing the inner wall of the oil bin 13 is better.

The package 2 is hollow, i.e. a first receiving cavity 23 is provided therein. The package 2 is made of a silicone material, so that the package 2 has good elasticity and sealing capability. When the package 2 is sleeved on the flow guide member 3, the flow guide member 3 is located in the first accommodating cavity 23 of the package 2.

The packaging part 2 is provided with a liquid outlet 24 and a first through hole 25, the liquid outlet 24 is communicated with the first accommodating cavity 23 and the oil bin 13, and aerosol substrate in the oil bin 13 can flow to the first accommodating cavity 23 through the liquid outlet 24. The liquid outlet holes 24 are two and are respectively positioned at two sides of the first through hole 25. It is understood that in other embodiments, one, three or more than three exit holes 24 may be provided, which is not limited herein.

The first through hole 25 is sealingly plugged with the vent post 14 (shown in fig. 2) to prevent escape of aerosol substrate within the sump 13. The vent pillar 14 has a vent channel 141 communicating with the first receiving chamber 23.

Referring to fig. 5 and 6, the flow guide member 3 is provided with a second through hole 31, and the second through hole 31 is hollow with two open ends. The two ends of the second through hole 31 are respectively communicated with the first through hole 25 and the heating structure 102, and the aerosol generated by the heating structure 102 can flow into the air outlet channel 141 through the second through hole 31 and the first through hole 25 in sequence.

The flow guide member 3 is provided with a flow guide channel 32, two ends of the flow guide channel 32 penetrate through the flow guide member 3, one end of the flow guide channel 32 is communicated with the liquid outlet hole 24, and the other end is communicated with the heating structure 102. Therefore, the oil sump 13 is sequentially communicated with the liquid outlet 24, the flow guiding channel 32 and the heating structure 102, and the aerosol substrate in the oil sump 13 can sequentially flow to the heating structure 102 through the liquid outlet 24 and the flow guiding channel 32, so that the heating structure 102 can heat and atomize the flowing aerosol substrate into aerosol.

The inner wall of the guide passage 32 is partially inclined, i.e., a guide slope 321. The lower end of the flow guiding ramp 321 is close to the heating structure 102 so that the aerosol substrate is more easily flowed to the heating structure 102 by the guiding action of the flow guiding ramp 321. The two flow guide passages 32 are respectively located at two sides of the second through hole 31. In other embodiments, one, three, or more than three flow guide channels 32 may be provided, which is not limited herein.

The outer wall of the flow guide member 3 has four air passage units 33, and two air passage units 33 are respectively provided at both sides of the flow guide member 3. It is understood that in other embodiments, the number of the air passage units 33 provided in the flow guide 3 may also be one, two, three, five or more, and is not limited herein.

Each air passage unit 33 is communicated with the oil sump 13 and the heating structure 102. Since the heating structure 102 is in turn communicated with the air outside the casing 1 through the second through hole 31, the first through hole 25 and the air outlet channel 141, the air channel unit 33 is communicated with the air outside the casing 1, that is, the oil sump 13 is communicated with the outside air through the air channel unit 33. As the aerosol substrate is heated and atomized by the heating structure 102, the aerosol substrate in the oil bin 13 gradually decreases, and the negative pressure formed in the oil bin 13 can be released through the air passage unit 33 in sequence, so that the aerosol substrate in the oil bin 13 can continue to flow to the heating structure 102 by its own weight.

In addition, the air passage unit 33 can store a certain amount of liquid. When the aerosol generated by the heating structure 102 flows to the air passage unit 33 to be liquefied to form condensate, the condensate can be stored in the air passage unit 33, meanwhile, the air passage unit 33 can still continuously communicate the oil bin 13 with the outside air, and the oil bin 13 can continuously release pressure.

The air passage unit 33 includes a pressure release passage 331, and a first storage chamber 332, a second storage chamber 333, a third storage chamber 334, and an air vent 335 communicating with the pressure release passage 331, the pressure release passage 331 communicating with the oil sump 13 and the air vent 335, the air vent 335 communicating with outside air to enable the oil sump 13 to release pressure.

Since the first storage chamber 332, the second storage chamber 333, and the third storage chamber 334 are not on the extending path of the relief passage 331, the relief passage 331 is not blocked even if the plurality of storage chambers store condensate, and the sump 13 can be communicated with the outside air. It should be emphasized that the number of the storage chambers is not limited, and one, two, four or more than four storage chambers may be provided, which is not limited herein.

One side of the diversion element 3, which is back to the diversion channel 32, is provided with a ventilation cavity 34, and the ventilation cavity 34 is communicated with the ventilation hole 335 and the outside air.

When the base 5 is in clamping fit with the flow guide part 3, the base 5 and the flow guide part 3 can clamp and fix the middle part 4 in the middle, and the first air pressure balance groove 52 is communicated with the middle hole 44.

The base 5 is further provided with air inlet holes 54, and the number of the air inlet holes 54 is nine, and the air inlet holes are arranged in an array.

Therefore, even if the first air pressure equalizing groove 52 and the second air pressure equalizing groove 53 are filled with condensate, the communication of the intermediate hole 44 with the outside air is not blocked, and the communication of the outside air to the sump 13 is not affected.

Second mounting hole 55 has still been seted up to base 5, and second mounting hole 55 has two, and two second mounting holes 55 communicate two first mounting holes 43 respectively, and first mounting hole 43 and second mounting hole 55 can be worn to establish in order and expose externally to the one end of two electrode rods 9. When the power supply assembly is connected to the atomizing assembly 100, the two electrode rods 9 are electrically connected to the battery of the power supply assembly.

The base 5 is provided with a mounting groove 56 along the peripheral side thereof, and the mounting groove 56 is sleeved with a sealing ring 57. Sealing ring 57 is a silica gel material for abutting the inner wall of bottom case 6, preventing the internal air leakage of base 5.

The second accommodating cavity 61 is used for accommodating the base 5, and the sealing ring 57 on the base 5 is tightly attached to the cavity wall of the second accommodating cavity 61 to ensure the sealing performance of the base 5.

Second clamping holes 62 are formed in two sides of the bottom shell 6, and the second clamping holes 62 are used for being in clamping fit with the first clamping flanges 12 of the shell 1, so that a plurality of other parts are packaged.

Referring to fig. 2 and 3, the heating structure 102 includes a heating body 7, a spacer 8, and the two electrode rods 9, and the heating body 7 is disposed between the spacer 8 and the two electrode rods 9. One end of each of the two electrode rods 9 is connected with the anode and the cathode of the heating body 7 respectively. The gasket 8 is made of silica gel, and can also be made of other elastic materials. The two ends of the gasket 8 are respectively abutted to the heating body 7 and the flange of the diversion piece 3, so that the heating body 7 is prevented from directly contacting the diversion piece 3.

The middle part of the gasket 8 is provided with a third through hole 81 in a penetrating way, the third through hole 81 is communicated with the heating body 7 and the flow guide channel 32 of the flow guide part 3, so that the aerosol substrate can flow to the heating body 7 through the third through hole 31, and then the heating body 7 can heat and atomize the aerosol substrate into aerosol after being electrified.

Referring to fig. 10, it is emphasized that the heating body 7 has a certain gap with the inner wall of the guide 3, which communicates the air flow hole 41 and the air outlet passage 141. The heating body 7 generates aerosol that can flow out from the air outlet passage 141.

Referring to fig. 11, fig. 11 shows a main schematic of the airway of the present invention. It should be noted that the air inlet 54, the airflow hole 41, the airflow groove 42, the second through hole 31, and the air outlet channel 141 together form the atomizing channel 15, and it can be understood that the length extending direction of the atomizing channel 15 is parallel to the length extending direction of the housing 1, and both ends of the atomizing channel are communicated with the outside air of the housing 1. When the user sucks the mouthpiece 11 with his mouth, the outside air can enter the atomizing passage through the air inlet 54, and the air flow is mixed with the aerosol generated by the heating body 7 and then enters the user's mouth through the air outlet 141.

The second air pressure balance groove 53, the first air pressure balance groove 52, the middle hole 44, the ventilation cavity 34, the vent 335 and the pressure release channel 331 form a ventilation channel 16, and it can be understood that one end of the ventilation channel 16 is communicated with the oil bin 13, and the other end is communicated with the atomization channel 15. Since the atomizing passage 15 communicates with the outside air, the ventilation passage 16 communicates with the outside air, and the oil sump 13 is depressurized.

The flow guide part 3 further comprises a one-way valve 36, one end of the one-way valve 36 is rotatably connected with the side wall of the flow guide part 3, and the free end of the one-way valve 36 can only rotate towards the inside of the oil bin 13. A torsion spring (not shown) may be provided at the location where the one-way valve 36 is pivotally connected. In a natural state, the torsion spring can drive the one-way valve 36 to close the outlet of the oil bin 13 by elastic force.

When the user sucks the suction nozzle 11, the atomizing passage 15 is in a negative pressure state, and the atomizing passage 15 communicates with the ventilation passage 16, so that the ventilation passage 16 is also in a negative pressure state. Since the check valve 36 cannot be rotated toward the outside of the oil sump 13, the outlet of the oil sump 13 is still in a closed state. The heating body 7 can be made of a ceramic material, which has natural pores. In addition, the heating body 7 is communicated with the oil bin 13, the atomizing channel 15 can have certain suction force to the oil bin 13 through the pores of the heating body 7, and the aerosol substrate 10 can flow to the heating body 7 more by the aid of the gravity of the aerosol substrate 10, so that the aerosol substrate 10 is atomized into aerosol by the heating body 7.

Along with the aerosol substrate in the oil bin 13 gradually decreases, the negative pressure in the oil bin 13 gradually increases until the one-way valve 36 is driven to overcome the elastic force of the torsion spring and rotate towards the inside of the oil bin 13, so that the oil bin 13 is communicated with the ventilation channel 16, and the air in the ventilation channel 16 enters the oil bin 13 to release the pressure to the oil bin 13. The negative pressure of the oil sump 13 is gradually reduced until it reaches equilibrium, so that the aerosol substrate 10 of the oil sump 13 can continue to flow into the heating body 7 by its own weight.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, various changes, substitutions and alterations can be made without departing from the spirit and scope of the invention. Therefore, the protection scope of the present patent shall be subject to the claims.
