In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1 and 2, an aerosol generating device according to an embodiment of the present application includes a battery assembly 2000, an atomizing assembly 1000 and a suction nozzle 3000; the battery assembly 2000 is electrically connected with the atomizing assembly 1000, and the battery assembly 2000 is used for supplying power to the atomizing assembly 1000 so as to start atomizing the atomizing assembly 1000; the atomizing assembly 1000 is for atomizing tobacco tar into aerosol particles; the mouthpiece 3000 communicates with the atomizing assembly 1000 and is used to deliver aerosol particles generated by the atomizing assembly 1000 to the mouth of the smoker.

Referring to fig. 3 to 5, in one embodiment, the atomization assembly 1000 includes a housing assembly 100 and a heating element 200, the housing assembly 100 is formed with an oil chamber 140 and an atomization chamber 150 that are disposed at intervals, and the heating element 200 is disposed in the housing assembly 100 and communicates the oil chamber 140 and the atomization chamber 150; the heating element 200 comprises an atomization surface 202 communicated with the atomization bin 150, the shell assembly 100 is further provided with an air inlet channel 101 and a ventilation channel 160, the air inlet channel 101 is communicated with the atomization bin 150, the ventilation channel 160 is communicated with the oil bin 140, the atomization bin 150 is isolated from the ventilation channel 160, the shell assembly 100 comprises an air channel wall 102 forming the ventilation channel 160, and the air channel wall 102 is at least partially positioned in the atomization bin 150.

The heating element 200 is communicated with the oil bin 140 and the atomization bin 150, and may be a position where the heating element 200 is arranged in the oil bin 140 and is connected with the atomization bin 150; alternatively, the heating element 200 is arranged between the atomization bin 150 and the oil bin 140; alternatively, the heat generating element 200 is provided in the atomizing area 150 at a position in contact with the oil sump 140.

According to the atomization assembly 1000 provided by the application, when the heating element 200 starts to work and part of tobacco tar in the oil bin 140 is consumed, the negative pressure of the oil bin 140 is increased, and the gas in the ventilation channel 160 enters the oil bin 140 to keep the balance of internal and external air pressure. Based on this, in the first aspect, due to the influence of the viscosity of the tobacco tar, the gas entering the oil bin 140 does not rise to the empty bin position of the oil bin 140 immediately, but rises slowly, so that the tobacco tar can be pressurized, so as to be extruded to the oil inlet end of the heating element 200 as much as possible, thereby increasing the fluidity of the tobacco tar in the oil bin 140, improving the oil supply speed of the tobacco tar in the oil bin 140, and ensuring smooth ventilation; in the second aspect, since the ventilation channel 160 is isolated from the atomization chamber 150, the smoke oil is sucked from the atomization chamber 150 to the ventilation channel 160 without being affected by the suction resistance of the suction airflow when the smoker sucks, so that the blockage of the ventilation channel 160 due to the influence of the suction resistance of the suction airflow can be avoided. Meanwhile, through the setting of the atomizing face 202 of the heating element 200 communicated with the atomizing bin 150, the atomizing face 202 can generate high-temperature aerosol, so that the temperature in the atomizing bin 150 is high, the air passage wall 102 of the air exchanging channel 160 is at least partially positioned in the atomizing bin 150, and accordingly, the temperature in the atomizing bin 150 can be transferred to high-viscosity oil in the air exchanging channel 160 and near the air exchanging channel 160 through the air passage wall 102, the mobility of tobacco tar is further increased, and accordingly the tobacco tar can be smoothly exchanged, additional power is not required to be increased, energy consumption and cost can be reduced, meanwhile, a circuit structure is not required to be increased, the structure of the atomizing assembly 1000 is simplified, the size of the atomizing assembly 1000 is reduced, and the atomizing assembly is convenient to carry.

Because the tobacco tar characteristics of the highly viscous tobacco tar (the higher the temperature, the lower the viscosity, and the higher the viscosity) generally cannot be used in a reverse flow process, but the forward flow process has the problem of oiling and extruding liquid, the ventilation channel 160 is communicated with the oil bin 140, and part of tobacco tar in the process of filling the oil bin 140 is extruded into the ventilation channel 160 under the action of air pressure to cause the blockage of the ventilation channel 160.

In one embodiment, as shown in FIG. 6, the ventilation channel 160 is located beside the nebulization cartridge 150, and the heat of the nebulization cartridge 150 can be conducted to the ventilation channel 160. Aerosol particles atomized by the heating element 200 are also provided with certain heat after being led into the atomization bin 150, and the ventilation channel 160 is positioned beside the atomization bin 150, so that the heat of the atomization bin 150 can be conducted to the ventilation channel 160, tobacco tar entering the ventilation channel 160 due to oiling extrusion liquid in the ventilation channel 160 can be heated, the tobacco tar extruded into the ventilation channel 160 due to oiling extrusion liquid has fluidity, and the tobacco tar can be ventilated smoothly.

In one embodiment, as shown in FIG. 6, the heat generating element 200 is disposed longitudinally between the atomizing cartridge 150 and the sump 140, the heat generating element 200 having an oil inlet face 201 facing the sump 140 and an atomizing face 202 facing the atomizing cartridge 150.

The longitudinal direction refers to a direction extending along the axial direction of the atomization assembly 1000, for example, the heat generating component 200 is disposed along a direction parallel to the axial direction of the atomization assembly 1000, or the heat generating component 200 is disposed at an oblique angle to the axial direction of the atomization assembly 1000, and generally, the extending trend of the heat generating component 200 is the same as that of the axial direction of the atomization assembly 1000, that is, the heat generating component 200 is mounted on the side surface of the atomization chamber 150, and the oil inlet surface 201 and the atomization surface 202 of the heat generating component 200 are disposed substantially parallel to the air flow direction in the atomization chamber 150. In fact, in the design, the thickness between the oil inlet surface 201 and the atomizing surface 202 of the block-shaped heating element 200 is generally designed to be smaller, and the area of the oil inlet surface 201 of the heating element 200 is designed to be larger, so that the design of mounting the heating element 200 on the side surface of the atomizing bin 150 according to the present application can reduce the lateral occupation space of the heating element 200. It will be appreciated that in other embodiments of the present application, the heat generating member 200 may be disposed laterally within the atomizing cartridge 150, as the structural volume of the atomizing assembly 1000 permits, and is not limited solely herein.

The axial direction according to the present application refers to the axial direction of the housing assembly 100, and when the housing assembly 100 is substantially cylindrical, the axial direction of the housing assembly 100 refers to the central axial direction of the housing assembly 100; when the housing assembly 100 is irregularly formed, the axial direction of the housing assembly 100 refers to the length extension direction of the housing assembly 100.

Meanwhile, since the ventilation channel 160 is located beside the atomization bin 150, the heating element 200 is mounted on the side surface of the atomization bin 150, aerosol particles atomized by the heating element 200 will be shot to the wall surface of the atomization bin 150 opposite to the heating element 200, so that the temperature of the wall surface of the atomization bin 150 opposite to the heating element 200 can be higher, and more heat can be transferred into the ventilation channel 160 through the wall surface of the atomization bin 150.

In practical applications, the air inlet end 161 of the ventilation channel 160 may be in communication with the outside air, or may be in communication with other air passages in the housing assembly 100, so long as the ventilation channel 160 is isolated from the atomization chamber 150, and those skilled in the art may select the arrangement according to the actual needs.

In one embodiment, the air inlet channel 101 includes a first channel (not shown) and a second channel (not shown), the first channel is in communication with the atomization chamber 150, and the second channel is in communication with the ventilation channel 160, so as to isolate the atomization chamber 150 from the ventilation channel 160. Specifically, when the smoker sucks the suction nozzle 3000, the external air enters the atomization chamber 150 through the first channel, and is also affected by the air flow, the tobacco tar in the oil chamber 140 enters the heating element 200, the aerosol particles heated and atomized by the heating element 200 are guided into the atomization chamber 150, and then enter the suction nozzle 3000 from the atomization chamber 150 under the influence of the air flow, and then enter the oral cavity of the smoker through the suction nozzle 3000. When the heating element 200 starts to work and part of tobacco tar in the oil bin 140 is consumed, the negative pressure in the oil bin 140 will be increased, and in order to keep the balance of the internal and external air pressures, the gas in the second channel will enter the oil bin 140 through the ventilation channel 160, so that the mobility of the tobacco tar in the oil bin 140 is increased, and smooth ventilation is ensured.

In one embodiment, referring to fig. 6, the inlet end 161 of the ventilation channel 160 is in communication with the ambient atmosphere, wherein the darkened arrows indicate the direction of fluid flow, wherein the middle, bottom-up flow arrows indicate the flow of gas in the airflow channel of the atomizing assembly 1000, the left arrow indicates the downward and rightward flow of tobacco tar in the sump 140 to the heat generating component 200, and the right arrow indicates the downward and upward flow of ambient atmosphere through the ventilation channel 160 to the sump 140. Specifically, when the smoker sucks the suction nozzle 3000, external air enters the atomization chamber 150 from bottom to top, and is also influenced by air flow, tobacco tar in the oil chamber 140 enters the heating element 200, aerosol particles heated and atomized by the heating element 200 are guided into the atomization chamber 150, then enter the suction nozzle 3000 from the atomization chamber 150 under the influence of air flow, and then enter the oral cavity of the smoker through the suction nozzle 3000. When the heating element 200 starts to work and part of tobacco tar in the oil bin 140 is consumed, the negative pressure of the oil bin 140 will be increased, and in order to keep the balance of the internal and external air pressure, the external atmosphere will enter the oil bin 140 through the ventilation channel 160, so that the mobility of the tobacco tar in the oil bin 140 is increased, and smooth ventilation is ensured.

In one embodiment, referring to fig. 6 and 8, the atomizing assembly 1000 further includes a seal 300, and the heat generating member 200 is sealingly mounted between the oil reservoir 140 and the atomizing reservoir 150 by the seal 300. Wherein, the arrangement of the sealing member 300 enables the connection between the heating member 200 and the housing assembly 100 to be sealed, so that the tobacco tar in the oil bin 140 can not flow from the gap between the heating member 200 and the housing assembly 100 to the atomization bin 150, thereby reducing the risk that the tobacco tar which is not atomized is directly sucked into the mouth of a smoker.

In one embodiment, referring to fig. 3 and 8, the atomizing assembly 1000 further includes a connection electrode 400 and an electrode support 500, the electrode support 500 is disposed in the mounting base 110, the connection electrode 400 is mounted on the electrode support 500, the electrode block 115 extends on the surrounding plate 113 of the mounting base 110, the connection electrode 400 and the electrode block 115 are respectively electrically connected with the two connection portions 203 on the heat generating component 200, and the mounting base 110 and the connection electrode 400 are respectively electrically connected with the battery assembly 2000, so that the heat generating component 200 can be powered through the battery structure. Since the electrode block 115 extends on the enclosing plate 113 of the mounting base 110, the connection electrode 400 and the electrode block 115 are respectively electrically connected with the two connection parts 203 on the heating element 200, and the electrode bracket 500 can be used for mounting and positioning the connection electrode 400 and realizing insulation between the connection electrode 400 and the mounting base 110.

In one embodiment, referring to fig. 7-10, the first receiving chamber 121 extends axially and the second receiving chamber 111 extends circumferentially and is disposed around the atomizing cartridge 150, the first receiving chamber 121 having a smaller circumferential dimension than the second receiving chamber 111. In this way, the difficulty of high-viscosity tobacco tar flowing into the ventilation channel 160 from the first accommodation chamber 121 communicating with the sump 140 can be increased; meanwhile, since the second accommodating cavity 111 extends along the circumferential direction and is arranged around the atomization bin 150, more heat can be transferred from the atomization bin 150 to the second accommodating cavity 111, and after sufficient waste heat is transferred to the first accommodating cavity 121, the gas in the second accommodating cavity 111 finally enters the oil bin 140, so that the fluidity of tobacco tar in the ventilation channel 160 and the oil bin 140 is increased.

In one embodiment, referring to fig. 7 to 10, an oil storage cavity 170 is provided on an inner bottom wall of the second accommodating cavity 111, and tobacco tar in the first accommodating cavity 121 can flow into the oil storage cavity 170, and an axial height of the oil storage cavity 170 is smaller than an axial height of the second accommodating cavity 111. Because the second accommodating cavity 111 is communicated with the external atmosphere, when high-viscosity tobacco tar enters the second accommodating cavity 111 through the first accommodating cavity 121 due to oiling and liquid squeezing or other reasons, the high-viscosity tobacco tar flows into the external atmosphere through the second accommodating cavity 111 to cause tobacco tar leakage, an oil storage cavity 170 is arranged on the inner bottom wall of the second accommodating cavity 111, and when the high-viscosity tobacco tar enters the second accommodating cavity 111 through the first accommodating cavity 121, the high-viscosity tobacco tar flows into the oil storage cavity 170 to be collected, so that the tobacco tar leakage is avoided; meanwhile, since the axial height of the oil storage cavity 170 is smaller than that of the second accommodating cavity 111, the oil storage cavity 170 can be prevented from interfering with the communication between the first accommodating cavity 121 and the second accommodating cavity 111, so that not only can the leakage of tobacco tar be avoided, but also the smooth ventilation of the ventilation channel 160 can be ensured.

In practical applications, the oil storage cavity 170 may be directly formed in the second accommodating cavity 111, or may be formed by enclosing the outer sidewall of the shroud 113 of the mounting seat 110, the inner sidewall of the oil pipe 130, and other structures disposed in the second accommodating cavity 111.

In one embodiment, referring to fig. 8 and 9, the inner bottom wall of the second receiving chamber 111 is provided with a first sealing rib 180 and a second sealing rib 190; the first sealing rib 180 and the second sealing rib 190 are respectively positioned at two sides of the first accommodating cavity 121 in the circumferential direction and extend along the axial direction, the dimension of the first sealing rib 180 and the second sealing rib 190 in the axial direction is smaller than that of the second accommodating cavity 111 in the axial direction, the first sealing element 300 and the second sealing rib 190 are prevented from interfering the communication of the first accommodating cavity 121 and the second accommodating cavity 111, and smooth ventilation of the ventilation channel 160 is ensured; the oil storage cavity 170 is formed by the first sealing rib 180, the second sealing rib 190, the oil pipe 130 and the mounting seat 110.

The first sealing rib 180 and the second sealing rib 190 are respectively located at two sides of the first accommodating cavity 121 in the circumferential direction, so that after tobacco tar in the oil bin 140 enters the first accommodating cavity 121, the tobacco tar can enter the oil storage cavity 170 under the action of gravity.

In one embodiment, referring to fig. 3, the cartridge tube 120 and the oil tube 130 are both hermetically connected to the mouthpiece 3000 via a sealing sleeve 4000, so as to prevent the escape of tobacco tar into the cartridge tube 120 or out of the tube.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
