As shown in fig. 1 to 10, the present invention proposes an aerosol generator comprising a main body 1 provided with a housing 11, an atomizing core assembly 2 having an atomizing passage 24, and a housing 3 provided with a suction port 321. Atomizing core subassembly 2 is inserted and is located in the accepting

groove

11, 3 covers of casing are located atomizing core subassembly 2, and with atomizing core subassembly 2's periphery forms oil storage chamber 4, suction port 321 with atomizing passageway 24 is linked together. The periphery of atomizing core subassembly 2 be equipped with the oilhole 211 of crossing that atomizing passageway 24 is linked together, accepting groove 11 is equipped with first locating part 13 and second locating part 14 along the direction of keeping away from the notch in proper order. When the housing 3 is fitted to the first stopper 13, the housing 3 blocks the oil passing hole 211 to isolate the oil storage chamber 4 from the atomizing channel 24. When the housing 3 is fitted to the second stopper 14, the housing 3 releases the oil passing hole 211 to communicate the oil storage chamber 4 with the atomizing passage 24. In the present embodiment, the housing 3 is mounted at different positions of the main body 1 to open/close the oil passing hole 211, thereby communicating and isolating the oil storage chamber 4 with the atomizing passage 24. Like this, under the condition that oil storage chamber 4 was annotated with the tobacco tar, can completely cut off oil storage chamber 4 and atomizing passageway 24 through keeping casing 3 at the state with first locating part 13 complex, prevent that the tobacco tar in the oil storage chamber 4 from leaking from atomizing passageway 24 in the tobacco tar infiltration atomizing passageway 24. On the other hand, when the user needs to use the aerosol generator, the housing 3 can be pushed into the second limit member 14 to be matched with the second limit member, so that the oil storage cavity 4 and the atomizing channel 24 can be communicated, and the operation is convenient.

As shown in fig. 6-7 and 9-10, the atomizing core assembly 2 includes a heating member 23, an oil guide member 22, and an air guide tube 21. The heating member 23 is formed by winding a heating wire, has a hollow columnar structure, and may be formed by winding a porous sheet-shaped heating element or by winding a heating wire. The heating member 23 may employ a metal heating element, a ceramic heating element, or the like. The oil guide member 22 is sleeved on the heating member 23 and is plugged into the hollow air duct 21 together with the heating member 23, so as to form an atomization passage 24. Correspondingly, the gas guide tube 21 is also a hollow tubular structure, and is correspondingly provided with an atomizing section for accommodating the heating element 23 and the oil guide element 22. Wherein, the diameter of the atomizing section is larger than the diameter of the other parts of the air duct 21. In this way, sufficient atomization space is provided for the atomization reaction.

One end of the air duct 21 is inserted into the bottom wall of the accommodating groove 11, and the bottom wall of the accommodating groove 11 corresponding to the air duct 21 is provided with an inserting hole 12 for installing the air duct 21. The air duct 21 is in interference fit with the insertion hole 12, so that the whole atomizing core assembly 2 is fastened in the accommodating groove 11. At the same time, the heating member 23 leads out terminals from the air duct 21, through which it is electrically connected to the power supply elements housed in the main body 1.

Further, as shown in fig. 1, a through oil passing hole 211 is formed in a tube wall of the air duct 21, the oil passing hole 211 is located in the accommodating groove 11, and the housing 3 is subsequently mounted to communicate the oil storage cavity 4 with the atomization passage 24. Thus, the oil passing hole 211 allows the smoke stored in the oil storage chamber 4 to enter the atomization passage 24, and the smoke is absorbed by the oil guide member 22 and atomized by the heating member 23. Preferably, the oil passing hole 211 is formed in the atomizing section, so that the path of oil absorbed can be reduced, the atomizing efficiency can be improved, and the oil can be prevented from being collected in the atomizing passage 24.

In the present embodiment, as shown in fig. 2, 6 and 9, the housing 3 includes a body 31 having an oil hole 316, and an upper cover 32, wherein one end of the body 31 is received in the receiving slot 11, and the other end of the body is exposed from the notch of the receiving slot 11, and the upper cover 32 covers the exposed end of the body 31. The body 31 includes a sleeve 312, a base 311 and a cover 313, wherein the sleeve 312 is a hollow structure with two open ends. The base 311 and the cover 313 are respectively mounted on the sleeve 312 from openings at both ends, and are connected with the sleeve 312 in a sealing manner. Such that the base 311, cover 313 and sleeve 312 enclose a sealed chamber. Wherein, the base 311 includes a base body 3111 and a first sealing member 3112, the base body 3111 is made of a hard glue material, for example, plastic, engineering plastic, etc. The first sealing member 3112 is made of soft rubber material, such as silicone rubber, and silicon rubber. The base body 3111 covers an opening at one end of the sleeve 312, and the first sealing member 3112 is located between an inner wall of the sleeve 312 and the base body 3111 and is pressed by the inner wall of the sleeve 312 and the base body 3111. Thereby first sealing member 3112 respectively with the two elasticity butt, the clearance between shutoff sleeve 312 inner wall and base body 3111 realizes the opening of sealed sleeve 312 one end, prevents that follow-up tobacco tar from leaking out in the sleeve 312.

Further, a first mounting groove (not shown) is concavely formed in one side of the base body 3111 for pressing the first sealing element 3112, the first sealing element 3112 is partially sunk into the first mounting groove, and the first sealing element 3112 is limited by the first mounting groove, so that relative displacement between the first sealing element 3112 and the base body 3111 and/or the sleeve 312 is prevented from affecting the sealing effect. Further, at least one first rib may be further disposed in the first mounting groove in a protruding manner, and correspondingly, the first sealing member 3112 is provided with a first groove adapted to the first mounting groove, and the first rib is accommodated in the first groove and is in interference fit with the first groove. Therefore, the position of the first sealing member 3112 can be further limited, and the contact area between the first sealing member 3112 and the base body 3111 can be increased, so that the sealing structure is more stable, and the sealing performance is improved.

The cover 313 includes a cover body 3131 and a second sealing element 3132, the cover body 3131 is made of a hard glue material, and the second sealing element 3132 is made of a soft glue material. The cover body 3131 covers the opening at the other end of the sleeve 312, and the second sealing element 3132 is located between the inner wall of the sleeve 312 and the cover body 3131 and is pressed by the inner wall of the sleeve 312 and the cover body 3131 to seal the gap between the inner wall of the sleeve 312 and the cover body 3131. The second sealing element 3132 thus elastically abuts both and seals the opening at the other end of the sleeve 312, preventing subsequent oil from leaking out of the other end of the sleeve 312.

Further, a second mounting groove is concavely formed on one side of the cover body 3131 pressing the second sealing element 3132, and a portion of the second sealing element 3132 sinks into the second mounting groove, so that the second sealing element 3132 is limited by the second mounting groove. At least one second convex rib can be arranged in the second mounting groove in a protruding mode, and correspondingly, a second groove matched with the second sealing element 3132 is formed in the second mounting groove. Thus, not only the position of the second sealing element 3132 can be limited, but also the contact area between the second sealing element 3132 and the cover body 3131 can be increased, so that the sealing structure is more stable, and the sealing performance is improved.

In this embodiment, the base 311 is provided with a first mounting hole (not shown) therethrough, and the cover 313 is provided with a second mounting hole 3133 therethrough. The first and second mounting holes 3133 are coaxial, so that when the housing 3 is mounted in the accommodating groove 11, the first and second mounting holes 3133 are sequentially sleeved on the atomizing core assembly 2. In this way, the atomizing core assembly 2 penetrates through the sealed cavity surrounded by the base 311, the cover 313 and the sleeve 312, and the periphery of the atomizing core assembly 2 and the inner wall of the sealed cavity (the inner wall of the housing 3) form an oil storage cavity 4.

As shown in fig. 3, in this embodiment, at least one buckle 314 is symmetrically disposed on two opposite sides of the housing 3, and the at least one buckle 314 is located on the same horizontal plane. Preferably, the latch 314 is disposed on the base 311, and may be located on a surface of the base 311 facing in the front-rear direction, or may be located on a surface of the base 311 facing in the left-right direction. Since the surface area of the base 311 facing in the front-rear direction is large, the catch 314 is preferably provided on the surface of the base 311 facing in the front-rear direction. The number of the buckles 314 can be one, 2 or more. When there is one catch 314, one catch 314 is provided on each of the front and rear surfaces. When there are 2 catches 314, two catches 314 are provided on each of the front and rear surfaces. In this embodiment, 2 fasteners 314 are selected and used, and the two fasteners 314 are respectively symmetrically disposed on each surface, so that each surface receives a balanced force, which is beneficial to maintaining the position of the housing 3 stable.

The buckle 314 comprises a buckle body, one end of the buckle body is attached to the shell 3 and is fixedly connected with the shell 3, and the other end of the buckle body is sequentially provided with a stress surface, a first guide surface and a second guide surface along the direction far away from the suction port 321. The stress surface is perpendicular to the mounting direction of the housing 3, and when the buckle 314 is clamped into the corresponding clamping hole, the stress surface is attached to the corresponding hole wall of the clamping hole to prevent the buckle 314 from being stressed and being displaced in the direction opposite to the mounting direction. The first guide surface is perpendicular to the stress surface, the second guide surface is connected with the first guide surface, and the included angle is an obtuse angle. During installation, the second guide surface and the first guide surface sequentially slide along the clamping hole, so that the guide effect is realized.

Correspondingly, the first limiting member 13 is at least one first locking hole disposed on the inner wall of the accommodating cavity 11, and the second limiting member 14 is at least one second locking hole disposed on the inner wall of the accommodating cavity 11. As shown in fig. 5-7, in the present embodiment, when the housing 3 is installed in the receiving slot 11, the base 311 of the housing 3 is first installed into the receiving slot 11 from the opening of the receiving slot 11 until the at least one latch 314 is latched into the corresponding first latching hole, so that the pre-assembly of the housing 3 is completed. At this time, the first mounting hole is sleeved on the periphery of the gas guide tube 21, and the hole wall of the first mounting hole covers the oil passing hole 211 to seal the oil passing hole 211, so as to isolate the oil passing hole 211 from the oil storage chamber 4. Thus, the oil storage chamber 4 is not communicated with the oil passing hole 211, and air and liquid in the oil storage chamber 4 cannot enter the air guide pipe 21 through the oil passing hole 211. Therefore, the oil in the liquid storage cavity can be prevented from extending into the atomizing channel 24 in the transportation process and then leaking out of the air inlet under the action of air pressure difference. As shown in fig. 8-10, when the aerosol generator is required to be used, a downward pressure is continuously applied to the housing 3, and the housing 3 is moved downward relative to the atomizing core assembly 2 under the pressure. The at least one latch 314 is disengaged from the corresponding first latch hole under the action of the two guide surfaces, and moves downward to be latched into the second latch hole. At this time, the first mounting hole is sleeved on the periphery of the air duct 21, and the hole wall of the first mounting hole does not cover the oil passing hole 211, that is, the oil passing hole 211 is exposed to the oil storage cavity 4 and communicates with the oil storage cavity 4 and the atomizing channel 24. The oil in the oil chamber 4 can enter the air duct 21 through the oil passing hole 211 and be absorbed by the oil guide 22.

In an embodiment of the present invention, in addition to the above technical features, as shown in fig. 4, the oil hole 316 is provided in the cover 313. That is, the cover body 3131 and the second sealing element 3132 are both provided with through holes corresponding to the oil storage chamber 4, so as to form the oil filling hole 316. Preferably, the number of the oil injection holes 316 is two, and the two oil injection holes 316 are distributed on the cover body 313 in a non-central symmetrical manner by the atomizing core assembly 2. Correspondingly, the upper cover 32 is provided with two connecting columns 323 which are matched with the two oil injection holes 316. When the upper cover 32 is engaged with the body 31, the two connecting posts 323 are respectively accommodated in the corresponding oil holes 316, and the outer circumference of the connecting posts 323 elastically abuts against the second sealing member 3132, so as to seal the oil holes 316. Thus, the oil leakage from the oil filler hole 316 after the oil filling can be prevented.

Further, a first elastic buckle 33 and a second elastic buckle 34 are symmetrically arranged on two sides of the body 31. Preferably, the first elastic buckle 33 and the second elastic buckle 34 are disposed at two ends of the cover 313. That is, a first elastic buckle 33 and a second elastic buckle 34 are protruded on a side of the cover body 3131 away from the base 311. The first elastic buckle 33 and the second elastic buckle 34 have the same structure, and both include an elastic arm 331 and a buckle portion 332. One end of the elastic arm 331 is vertically connected to a side of the cover body 3131 away from the base 311, and the other end is suspended and can elastically swing with respect to the cover body 3131. The latching portion 332 is integrally connected to the suspended end of the elastic arm 331. In practical applications, the first elastic buckle 33 and the second elastic buckle 34 are made of a material with certain elasticity, for example, engineering plastics, metal, etc. with elasticity. Correspondingly, the upper cover 32 is provided with a first clamping groove matched with the first elastic buckle 33 and a second clamping groove 322 matched with the second elastic buckle 34, the first clamping groove is clamped into the first elastic buckle 33, the second elastic buckle 34 is clamped into the second clamping groove 322, the upper cover 32 is connected with the body 31, and the at least one oil filling hole 316 is sealed.

Further, referring to fig. 4 and 5, an acting force required for the first elastic buckle 33 and the second elastic buckle 34 to be clamped into the corresponding slots is smaller than an acting force required for the housing 3 to be disengaged from the first limiting member 13. That is, when the housing 3 is adapted to the first limiting member 13 to be pre-installed in the accommodating groove 11, and then the upper cover 32 is engaged, the first elastic fastener 33 and the second elastic fastener 34 are respectively engaged into the corresponding engaging grooves, and meanwhile, the housing 3 maintains the state of being adapted to the first limiting member 13, so that the oil passing hole 211 is kept in the blocked state. That is, the pressure applied to the upper cover 32 is greater than the force required for the first elastic buckle 33 and the second elastic buckle 34 to be clamped into the corresponding clamping grooves, and the pressure is less than the force required for the at least one clamping buckle 314 to be pulled out of the first clamping hole. Thus, when the user finishes injecting oil and engages the upper cover 32, the oil passing hole 211 is not communicated with the oil storage chamber 4, and the oil smoke injected into the oil storage chamber 4 cannot flow into the atomization passage 24. Thereby ensuring that the tobacco tar will not seep out from the atomizing channel 24 in the process from the oil injection to the aerosol generator suction of the user, resulting in the waste of the tobacco tar and the sanitary problem. When the upper cover 32 is further pressed down, the upper cover 32 applies pressure to the housing 3, and when the pressure applied to the housing 3 is greater than the force required for the at least one catch 314 to escape from the first catch hole, the housing 3 moves downward until the at least one catch 314 catches in the corresponding second catch hole. At this time, the oil hole 316 is opened and exposed to the oil storage chamber 4 to communicate the oil storage chamber 4 with the atomizing passage 24, so that the oil in the oil storage chamber 4 can be absorbed by the oil guide 22 through the oil passing hole 211.

Further, in order to guarantee that the shell 3 can smoothly move and avoid damaging the atomizing core assembly 2, a hollow support column 315 is further arranged in the body 31. One end of the supporting column 315 is interference-fitted in the first mounting hole, and the other end is interference-fitted in the second mounting hole 3133. The support column 315 is sleeved on the atomizing core assembly 2, and a first sealing ring 3153 and a second sealing ring 3152 are arranged between the support column 315 and the atomizing core assembly 2. Namely, the two sealing rings are accommodated in the supporting column 315 and are sleeved on the atomizing core assembly 2. The first sealing ring 3153 is disposed at one end of the supporting column 315 received in the first mounting hole, and when the buckle 314 is matched with the corresponding first clamping hole, the first sealing ring 3153 blocks the oil passing hole 211. The first sealing ring 3153 is elastically abutted against the inner side wall of the support column 315 and the outer side wall of the air duct 21, and the acting force between the inner side walls of the support column 315 is greater than the acting force between the outer side walls of the air duct 21. This ensures that the supporting post 315 and the first sealing ring 3153 can move together with the housing 3 relative to the atomizing core assembly 2 when the housing 3 is moved by an external force, so that the first sealing ring 3153 can move to release the oil passing hole 211. Further, a first bending portion is disposed at an end of the first sealing ring 3153 close to the bottom wall of the accommodating groove 11, and the first bending portion is wrapped on an end surface of the supporting pillar 315 close to the bottom wall of the accommodating groove 11. When the supporting pillar 315 moves towards the bottom wall of the accommodating groove 11, the first bending portion limits the first sealing ring 3153, so as to prevent the first sealing ring 3153 from moving together with the supporting pillar 315 under the action of the atomizing core assembly 2, and prevent the problem that the oil passing hole 211 cannot be released.

The second sealing ring 3152 is disposed at one end of the supporting pillar 315 close to the second mounting hole 3133, and the second sealing ring 3152 is elastically abutted against the inner sidewall of the supporting pillar 315 and the outer sidewall of the air duct 21, respectively. The acting force between the second sealing ring 3152 and the inner side wall of the supporting column 315 is larger than the acting force between the second sealing ring 3152 and the outer side wall of the air duct 21. This ensures that the support post 315 and the second sealing ring 3152 can both follow the housing 3 and move together relative to the atomizing core assembly 2 when the housing 3 is subsequently moved by an external force. Further, a second bending portion is disposed at an end of the second sealing ring 3152 facing the first sealing ring 3153. Correspondingly, the inner wall of the support column 315 is provided with a limit step. The second bending portion is attached to the limit step to prevent the second sealing ring 3152 and the supporting pillar 315 from generating relative displacement.

The supporting column 315 is provided with at least one window 3151, and the window 3151 communicates the hollow internal space of the supporting column 315 with the oil storage chamber 4, so that the periphery of the atomizing core assembly 2 accommodated in the supporting column 315 can be exposed in the oil storage chamber 4 through the window 3151 and can be completely immersed in oil. This embodiment provides protecting sheathing and holding power for atomizing core subassembly 2 through support column 315, prevents that atomizing core subassembly 2 from receiving the damage in the removal in-process of casing 3 to the stationarity and the security that casing 3 removed have been guaranteed.
