Because the atomizing subassembly structure is comparatively complicated, spare part is more, and this kind of atomizing subassembly of disposable design cost is higher. In particular, some areas have regulations on the oil amount of the oil storage bin in the aerosol generating device, some areas have regulations below 2ml, users need to frequently replace the oil storage bin and the electric heating element, and the use cost is higher.
The oiling atomization component comprises an oil storage bin and an oiling bin, wherein aerosol generated oil in the oil storage bin is used up, the oiling bin can be used for oiling the oil storage bin, the oil storage bin and the electric heating piece can be used repeatedly, and the use cost of the aerosol generating device is reduced.
The oiling and atomizing assembly of the aerosol-generating device of the present application is further described below in connection with the detailed description.
In some embodiments, referring to fig. 1 to 3, an oiling and atomizing assembly of an aerosol generating device comprises an atomizing assembly 1 and an oiling assembly 2, wherein the atomizing assembly 1 comprises an oil reservoir 11 and an electric heater 12, and the oiling assembly 2 comprises an oiling reservoir 21 and an oiling reservoir piston 22.
The oil reservoir 11 has an oil reservoir cavity (not shown) for storing aerosol-generating oil, and referring to fig. 7 and 8, the oil reservoir 11 further has an oil filler hole 111 communicating with the oil reservoir cavity. The sump 11 also has a sump air passage 112 extending through the sump cavity, the sump air passage 112 for allowing air flow when aerosol is drawn.
Referring to fig. 3, an air passage wall of the air passage 112 of the oil storage chamber has an oil passing hole 113 for communicating the air passage 112 of the oil storage chamber with an inner cavity of the oil storage chamber, and the oil passing hole 113 is used for enabling aerosol-generating oil in the inner cavity of the oil storage chamber to enter the air passage 112 of the oil storage chamber. At least a portion of the electrical heating element 12 is disposed in the sump air passage 112 for heating and atomizing the aerosol-generating oil entering the sump air passage 112 and enabling the generated aerosol to be carried away by the air flow in the sump air passage 112. The electric heating element 12 may be any feasible manner, such as a mesh-shaped heating jacket, a spiral-shaped heating wire, or a heating wire which is bent back and forth.
In order to be able to replenish the oil reservoir 11, please refer to fig. 3, 5 and 8, the oil reservoir 21 has an oil reservoir inner cavity 211 and an oil nozzle 212, wherein the oil reservoir inner cavity 211 is used for filling with aerosol-generating oil. The oil nozzle 212 is inserted into the oil filling hole 111, and the oil nozzle 212 communicates with the oil filling bin inner cavity 211, so that aerosol-generating oil in the oil filling bin inner cavity 211 can be injected into the oil filling bin inner cavity through the oil nozzle 212.
With reference to fig. 3, in this application, the sump piston 22 is movably assembled in the sump cavity 211, and the sump piston 22 is moved in the sump 21 toward the direction approaching the nozzle 212, so that the aerosol-generating oil in the sump cavity 211 can be squeezed into the sump cavity. In extruding the aerosol-generating oil in the oil sump 21, the use of the oil sump piston 22 makes it easier to control the amount of oil extruded.
Specifically, referring to fig. 3, the oil sump piston 22 includes a piston rod 221 and a piston body 222, and the piston body 222 is disposed in the oil sump 21 and slidably and sealingly engaged with an inner wall of the oil sump 21. The piston rod 221 extends out of the oil sump 21 to facilitate operation of the oil sump piston 22 to move the oil sump piston 22. The piston body 222 is made of an elastic material, and may be specifically made of rubber or silica gel.
In the oiling and atomizing assembly of the aerosol generating device, the oiling bin 21 is used for oiling the oil storage bin 11, so that the oil storage bin 11 can be reused, and the use cost is reduced. In addition, the amount of oil injected into the oil reservoir 11 is facilitated to be controlled by the reservoir piston 22.
The aerosol-generating oil in the present application is an oil liquid that can be atomized to generate aerosol after heating.
Regarding the manner of filling oil into the oil filling bin 21 and the oil storage bin 11, manner one: in some embodiments, referring to fig. 3, the oil injection bin 21 is inserted into and detachable from the oil storage bin 11, so that after the oil injection bin 21 is separated from the oil storage bin 11, the oil bin piston 22 moves in the oil injection bin 21 in a direction away from the oil nozzle 212, so that external aerosol generating oil can enter the inner cavity 211 of the oil injection bin; and then oil is injected into the oil storage bin 11 through the oil injection bin 21. Mode two: in some other embodiments, the oiling chamber 21 has an oiling hole for injecting aerosol-generating oil into the oiling chamber 21, and the oiling chamber 21 is directly filled with oil through the oiling hole, and then the oiling chamber 11 is filled with oil through the oiling chamber 21. Of course, in one embodiment, the oiling and atomizing assembly can also have the structure of the first mode and the structure of the second mode, and the oiling and atomizing assembly can be flexibly selected according to requirements during use.
Specifically, in one embodiment, referring to fig. 3, under the condition that the oil filling bin 21 is inserted into and detachable from the oil storage bin 11, by operating the oil bin piston 22, aerosol-generating oil can be sucked through the oil filling nozzle 212, so that the oil filling bin 21 is filled with the aerosol-generating oil. Specifically, the oiling bin 21 and the oil storage bin 11 are fixed by adopting a clamping connection, wherein a buckle (not shown in the figure) is arranged on the oiling bin, and a clamping groove for clamping the buckle is arranged on the oil storage bin. In some other embodiments, the oil storage bin 11 and the oil injection bin 21 can be fixed through a hoop, and a part of the hoop is used for hooping the oil injection bin 21 and a part of the hoop is used for hooping the oil storage bin 11, so that the oil storage bin 11 and the oil injection bin 21 are fixed. In still other embodiments, the oil reservoir 11 and the oil injection reservoir 21 may be secured by a connection plate, a portion of which is secured to the oil reservoir 11 by screws, and a portion of which is secured to the oil injection reservoir 21 by screws.
In some other embodiments, where the oiling chamber 21 has an oiling hole for injecting aerosol-generating oil into the oiling chamber 21, the aerosol-generating oil may be directly added to the oiling chamber 21 through the oiling hole, and the oiling chamber 21 and the oil storage chamber 11 may be fixed in a non-detachable manner, for example, the oiling chamber 21 and the oil storage chamber 11 may be fixed together by welding or riveting.
The oiling and atomizing assembly of the present application can be shipped from the factory, with the oil reservoir 11 and the oiling reservoir 21 being able to select whether to store aerosol-generating oil as desired.
In some embodiments, referring to fig. 3, at least one of the oil reservoir 11 and the oil injection reservoir 21 has aerosol-generating oil stored therein.
For example, in some embodiments, aerosol-generating oil is pre-stored in the oil reservoir 11, while aerosol-generating oil is also pre-stored in the oil injection reservoir 21. This way it is possible to meet the user's need not to change the type of aerosol-generating oil. When the oil is replenished after the aerosol-generating oil in the oil storage bin 11 is used, the aerosol-generating oil in the oil filling bin 21 is filled into the oil storage bin 11. In some embodiments, if the oil reservoir 11 needs to be replenished again, the oil filling reservoir 21 needs to be replenished first, and the type of aerosol generating oil may be changed as needed.
For another example, in some embodiments, aerosol-generating oil is pre-stored in the oil reservoir 11, while aerosol-generating oil is not pre-stored in the oil injection reservoir 21. This way, the user can choose to add different or the same type of aerosol generating oil to the oiling station 21 as desired. In addition, this approach is prone to meeting regulatory requirements in some areas for the amount of aerosol-generating oil in an aerosol-generating device. When the oil reservoir 11 is filled with the aerosol-generating oil after the use, the aerosol-generating oil needs to be filled into the oil reservoir 21, and then the aerosol-generating oil needs to be filled into the oil reservoir 11 through the oil reservoir 21.
For another example, in some embodiments, the aerosol-generating oil is not stored in the oil storage tank 11 in advance, but the aerosol-generating oil is stored in the oil filling tank 21 in advance, and the aerosol-generating oil in the oil filling tank 21 may be injected into the oil storage tank 11 before the aerosol is generated by using the aerosol-generating device. Since the aerosol-generating oil is not stored in the oil reservoir 11, it is less likely to leak the aerosol-generating oil through the oil reservoir air passage 112. This approach also tends to meet regulatory requirements in some areas for the amount of aerosol-generating oil in the aerosol-generating device. In some embodiments, if the aerosol-generating oil in the oil sump 21 is used up, and it is desired to continue to replenish the oil reservoir 11, then it is desired to fill the oil sump 21 with aerosol-generating oil.
In some embodiments, the oil reservoir 11 may not have aerosol-generating oil pre-stored therein, and the oil injection reservoir 21 may not have aerosol-generating oil pre-stored therein. Thus, the aerosol generating oil can be flexibly added according to the needs when the aerosol generating oil is used by a user. Of course, this approach also makes it easier to meet regulatory requirements in some areas for the amount of aerosol-generating oil in an aerosol-generating device. In one embodiment, before aerosol is generated using the aerosol-generating device, aerosol-generating oil is added to the oil sump 21 and then aerosol-generating oil is added to the oil reservoir 11 through the oil sump 21.
Further, in an embodiment, referring to fig. 3, 7 and 8, the oil storage bin 11 includes a bin barrel 114 and an elastic sealing cover 115 at one axial end of the bin barrel 114, and the oil filling hole 111 is located on the elastic sealing cover 115 and is in sealing fit with the oil filling nozzle 212. Through the elastic sealing cover 115, the bin 114 can be plugged, and meanwhile, the bin is conveniently sealed with the oil filling nozzle 212, so that leakage of aerosol generated oil is reduced or even avoided. Further, to facilitate oiling, in one embodiment, the nozzle 212 is inserted into the oil hole 111 and penetrates through the elastic sealing cover 115, so that the nozzle 212 is inserted to a deeper depth, and aerosol-generating oil can be injected into the inner cavity of the oil storage bin more quickly.
The elastic sealing cover 115 is made of silica gel, so that the elastic sealing cover is convenient to seal with the bin 114. The outer peripheral surface of the elastic sealing cover 115 is in sealing fit with the cartridge 114. The elastic sealing cover 115 and the bin 114 can be fixed in any feasible manner, for example, the elastic sealing cover 115 and the bin 114 can be fixed by bonding, for example, the elastic sealing cover 115 can be directly contracted and then plugged into the bin 114, and the elastic sealing cover 115 is deformed to provide elastic force to fix the bin 114.

The inner cavity of the oil storage bin is filled with a porous oil absorption body 14, and the porous oil absorption body 14 is used for absorbing aerosol-generating oil. Specifically, the porous oil absorbing body 14 is made of oil absorbing cotton. In some other embodiments, the porous oil absorbing body 14 may be made of felt, porous hard block, or the like.

The arrangement of the porous oil absorbing body 14 and the electric heating element 12 in the oil sump 11 is facilitated by forming at least a part of the oil sump air passage 112 through the oil sump air passage pipe 116. The inner layer oil guide 13 is capable of bringing an appropriate amount of aerosol-generating oil into contact with the electric heater 12 to generate an appropriate amount of aerosol.
Specifically, referring to fig. 4, the inner oil guide 13 is made of a porous material, and a portion of the inner oil guide 13 extends into the porous oil absorbing body 14 through the oil passing hole 113, so that aerosol-generating oil smoothly enters the inner oil guide 13. The material of the inner layer oil guide 13 can be the same as that of the porous oil absorbing body 14, such as oil absorbing cotton, felt, porous hard oil absorbing block, etc.
Specifically, referring to fig. 3, the oil passing hole 113 is a long waist hole, and the waist length extends along the axial direction of the oil reservoir air passage pipe 116. The oil passing holes 113 are provided in plurality and are uniformly spaced apart in the circumferential direction of the oil reservoir air passage pipe 116, so that the aerosol-generating oil is facilitated to enter the oil reservoir air passage pipe 116. In some other embodiments, the oil passing holes 113 may take any other feasible form, for example, may be round holes, polygonal holes, and the number of the oil passing holes 113 may be any number of one, two, three, etc. in the case that the strength of the oil storage bin air passage pipe 116 meets the requirement.

After the mount section 1181 is inserted into the mount hole 1171, the mount hole 1171 is widened, and the mount section 1181 is fixed by the elastic force of the mount section 1181 after the elastic mount 117 is deformed. The oil storage bin air passage pipe 116 is sleeved on the pipe mounting section 1182, and in this embodiment, the oil storage bin air passage pipe 116 is in interference fit with the pipe mounting section 1182 to achieve fixation.
In some other embodiments, the resilient mounting 117 of the oil reservoir 11 is replaced by a rigid mounting, where a gasket is added between the rigid mounting and the cartridge 114 for sealing. Similarly, in some other embodiments, the elastic sealing cover 115 of the oil storage bin 11 may also be a rigid sealing cover, and a sealing ring is added between the rigid sealing cover and the bin barrel 114 for sealing.
Further, in one embodiment, referring to fig. 8, the electric heating element 12 includes a heating jacket 121, a first electrode 122 and a second electrode 123, wherein one of the first electrode 122 and the second electrode 123 is a positive electrode, and the other is a negative electrode. The first electrode 122 and the second electrode 123 each pass through the airway tube holder 118 and are respectively used for connection with the positive and negative poles of a power supply module in an aerosol-generating device.
In this embodiment, referring to fig. 8, the wall of the heating jacket 121 is mesh-shaped. Specifically, the heating jacket 121 is formed by winding a mesh, so that the heating jacket 121 is an open jacket, the caliber of the heating jacket 121 is reduced after being installed, elastic deformation is generated, and the elastic force between the heating jacket 121 and the inner layer oil guide 13 enables the heating jacket 121 to be tightly supported on the inner layer oil guide 13.
With respect to the oil sump 21, in one embodiment, referring to fig. 3-6, the oil sump 21 has an oil sump air passage 213 extending through the oil sump air passage 112, the oil sump air passage 213 extending through the oil sump inner cavity 211 and being spaced from the oil sump inner cavity 211.

The oil sump piston 22 is penetrated by the oil sump air passage pipe 215 and is in sliding sealing fit with the oil sump piston 22 along the axial direction of the oil sump air passage pipe 215. The air duct 215 of the oiling bin penetrates through the oiling bin body 214, so that the tightness of the inner cavity 211 of the oiling bin is conveniently kept.
Specifically, referring to fig. 3, in one embodiment, the orifice of the oil sump airway tube 215 forms the entire oil sump airway 213. The oil injection bin air passage pipe 215 is fixed with the oil injection bin body 214. The specific fixing mode can be welding, fastening piece fixing or integral molding.
Further, to simplify the construction of the aerosol-generating device, in one embodiment, referring to fig. 3, the aerosol-extracting end 2152 protrudes from the oiling station 21 and forms a mouthpiece for aspirating aerosols. The suction nozzle allows the user to suck the oil filling bin air channel 213. The suction nozzle is positioned on the oil injection bin air passage pipe 215, so that the installation steps are reduced, and the installation efficiency is improved. In some other embodiments, the suction nozzle can be fixed with the oil filling bin air channel pipe 215 in a split mode, so that the suction nozzle processing is facilitated, and different types of suction nozzles can be selected according to requirements.

The position of the piston body 222 can be limited through the blocking cap 23, so that the quantity of aerosol-generating oil extruded by the oiling bin 21 each time is consistent, the oil supplementing of the oil storage bin 11 is facilitated, and the operation efficiency is improved. In addition, the guiding constraint of the guiding cylinder 232 prevents the oil sump piston 22 from shaking, and the movement process is smoother and has good stability. In some other embodiments, the piston rod 221 of the sump piston 22 is connected to the piston body 222 at one end and is free at the other end.
In one embodiment, one mode of use of the oiling atomizing assembly of the present application is as follows:
the aerosol-generating oil in the oil storage bin 11 is consumed when the aerosol-generating device is used, and the aerosol-generating oil in the oil storage bin 11 is consumed until the aerosol-generating oil in the oil storage bin 11 is used up, the oil bin piston 22 in the oil storage bin 21 is operated, and the aerosol-generating oil in the oil storage bin 21 is injected into the oil storage bin 11 for continuous use. The oiling can be continuously performed to the oiling bin 21, the oiling operation can be performed after the aerosol-generating oil in the oil storage bin 11 and the oiling bin 21 is used up, or the oiling operation can be performed after the aerosol-generating oil in the oiling bin 21 is used up, and thus the oiling atomization assembly can be reused.
In one embodiment, the maximum oil filling amount of the oil filling bin 21 corresponds to the maximum oil storage amount of the oil storage bin 11. The maximum oil filling amount of the oil filling bin 21, that is, the maximum oil amount extruded after the oil filling bin 21 is filled with aerosol-generating oil, and the maximum oil storage amount of the oil storage bin 11 means the maximum amount of aerosol-generating oil stored in the oil storage bin 11. Since the oil filling amount capacity of the oil filling bin 21 is fixed, the oil in the oil filling bin 21 can be fully filled into the oil storage bin 11 after the oil is fully filled into the oil storage bin 11. Of course, in some embodiments, when the aerosol-generating oil in the oil filling bin 21 is used up or when the aerosol-generating oil in the oil filling bin 21 is not present, the oil storage bin 11 may be filled with oil by inserting the injector into the oil filling hole 111 (refer to fig. 7), but the oil filling operation using the injector is complicated compared to the oil filling mode of the oil filling bin 21, in which the oil filling amount of the injector is not matched with the oil amount of the oil storage bin 11. Of course, in some embodiments, the maximum oil filling amount of the oil filling bin 21 may not be consistent with the maximum oil storage amount of the oil storage bin 11, for example, the maximum oil filling amount of the oil filling bin 21 is greater than the maximum oil storage amount of the oil storage bin 11, so that the aerosol-generating oil in the oil filling bin 21 may be injected into the oil storage bin 11 in two times.
In one embodiment, the oiling assembly 2 and the atomizing assembly 1 in the present application may be shipped separately, and whether the oiling assembly 2 is attached to the atomizing assembly 1 may be determined according to the need.
