Example 1:

as shown in fig. 1 and 2, the present embodiment provides a cartridge 100 with a raised atomizing core. The cartridge 100 of this embodiment is used with a tobacco rod 200 having a power source. The power supply in the tobacco rod 200 provides electrical power to the atomizing device 30 of the cartridge 100. the atomizing device 30 of the cartridge 100 provides electrical power that the atomizing device 30 converts to heat to atomize the tobacco tar stored in the tank 10 of the cartridge 100. When the user inhales through the mouthpiece 20, a negative pressure is created at the tobacco smoke outlet of the cartomiser 30 where the cartridge 100 has been atomised. Under the negative pressure, air enters the cartridge 100 from the air inlet 52 of the cartridge 100 and carries the atomized tobacco tar along the internal airflow path of the cartridge 100 to the mouthpiece 21 of the mouthpiece 20 for the user to inhale.

In the embodiment, the part of the protrusion 321 is arranged on the atomizing core 32, and the part of the protrusion 321 extends into the oil tank 10, so that the part of the atomizing core 32 generating heat can be soaked in the tobacco tar all the time, the contact area of the tobacco tar and the atomizing core is increased, the oil guiding rate is improved, and thus, the dry burning of the heating part of the atomizing core 32 under the condition that no tobacco tar is present is avoided. In addition because this embodiment directly establishes atomizing core 32 and soaks the tobacco tar in the tobacco tar and heat, the heat can be in the tobacco tar conduction diffusion gradually, makes the tobacco tar in the oil tank 10 form good temperature gradient around the protruding 321 part of atomizing core 32, can shorten the time that the tobacco tar atomizes like this, can make the atomizing to the tobacco tar more abundant again, can form the better flue gas of taste after mixing with the air.

As shown in fig. 2 and 3, the cartridge 100 with a protruding atomizing core of the present embodiment includes:

an oil tank 10 for storing tobacco tar;

in the present embodiment, the oil tank 10 serves as an oil storage component of the cartridge 100, and a receiving chamber for receiving the tobacco tar is formed in the oil tank 10. In specific implementation, part of the material in the oil tank 10 may be removed to form the accommodating chamber, and the oil tank 10 with the accommodating chamber may also be manufactured in an integrated molding manner. The opening of the receiving chamber, from which the tobacco tar is injected into the receiving chamber during production of the cartridge 100, opens on the side facing away from the smoking opening 21.

A cigarette holder 20 fixed on the oil tank 10 and provided with a smoking port 21;

in this embodiment, the mouthpiece 20 is sleeved outside the fuel tank 10 as a part of the outer shell of the cartridge 100, and when the user uses the cartridge, the mouthpiece 20 is held in the mouth to inhale, and the atomized smoke enters the mouth of the user through the smoking port 21 on the mouthpiece 20.

The atomizing device 30 is communicated with the chamber of the oil tank 10 for storing the tobacco tar and is used for atomizing the tobacco tar;

as shown in fig. 4 and 5, the atomizing device includes an atomizing core 32 for generating heat, and a protrusion 321 is formed on the atomizing core 32, and the protrusion 321 extends from a side of the atomizing core 32 facing the tank 10 into the tank 10, so that the atomizing core 32 heats the soot in the tank 10;

the atomizing core 32 in this embodiment is preferably an atomizing core 32 having good high temperature resistance. After the atomization device is powered on, the atomization core 32 converts the electric energy into heat energy to heat the tobacco tar, so that the tobacco tar is atomized and fully mixed with the air entering the cartridge 100, and then enters the mouth of the user through the smoking port of the cigarette holder for the user to smoke. The part of a arch 321 is arranged on the atomizing core 32, the part of the arch 321 extends into the oil tank 10, the part of the atomizing core 32 which generates heat can be soaked in the tobacco tar all the time, so that the heating part of the atomizing core 32 can not be burnt without the tobacco tar, the atomizing core 32 is burnt and damaged, burnt substances enter the mouth of a user along with the smoke easily, and the user experience is seriously influenced. In addition because this embodiment directly establishes atomizing core 32 and soaks the tobacco tar in the tobacco tar and heat, the heat can be in the tobacco tar conduction diffusion gradually, makes the tobacco tar in the oil tank 10 form good temperature gradient around the protruding 321 part of atomizing core 32, can shorten the time that the tobacco tar atomizes like this, can make the atomizing to the tobacco tar more abundant again, can form the better flue gas of taste after mixing with the air.

In addition, the embodiment further comprises a flue for guiding the smoke formed by the atomized smoke oil through the atomization device 30 to flow to the smoke suction port 21;

the oil tank base 40 is covered on one end of the oil tank 10 close to the atomizing device 30 and is connected with the atomizing device;

an opening 43 for communicating the atomizing device 30 with the oil tank is formed on the oil tank base 40

Wherein the cargo tank base 40 is used to seal the cargo tank 10 so as to prevent the smoke in the cargo tank 10 from leaking out of the cargo tank 10.

As shown in fig. 4, in the present embodiment, the protrusion 321 of the atomizing core 32 passes through the opening 43 of the cargo tank base 40 and extends to a position at a predetermined distance from the bottom of the cargo tank 10, so that the protrusion 321 is partially or completely immersed in the soot of the cargo tank 10 to generate heat.

Wherein the bottom of the cargo tank 10 refers to the end surface of the cargo tank 10 facing the atomizing device. The rest of the atomizing core 32, except for the projection 321, is located on the side of the opening 43 of the cargo tank base 40 opposite to the cargo tank 10. The protrusion 321 extends partially through the opening 43 into the cargo tank 10 so that the oil can be heated without passing through the opening 43, further avoiding the possibility of oil leaking from the location of the cargo tank base 40. The preset distance from the protrusion 321 to the bottom of the oil tank 10 can be designed according to actual use conditions, so that the protrusion 321 can be well soaked into the oil tank 10 to heat the smoke oil.

The atomizing end cover 50 is covered on one side, facing the atomizing device 30, of the oil tank base 40;

the present embodiment further includes an atomizing device fixing member 42 for fixing the position of the atomizing device 30 in the cartridge 100, the atomizing device fixing member 42 being integrally formed with the oil tank base 40 by in-mold injection;

in order to achieve sufficient atomization of the tobacco tar, the present embodiment requires that the atomization device 30 be fixed to the bottom of the cargo tank 10. The present embodiment is thus provided with an atomizing device fixing 42 with which the atomizing device 30 is fixed below the cargo tank 10. Because the atomizing device 30 has a high temperature during operation, the atomizing device fixing member 42 of this embodiment may be made of a material that is resistant to high temperature and fast in heat dissipation, and the atomizing device fixing member 42 is integrally formed with the oil tank base 40 by in-mold injection.

Wherein the in-mold injection molding is an existing integrated forming process. The atomizing device fixing member 42 and the oil tank base 40 are formed into an integrated in-mold injection structure through in-mold injection. The process of in-mold injection molding the atomizer mounting member 42 is to place the atomizer mounting member 42 at a specific location in a mold, and then to inject an injection molding material into the mold to finally form an integrated atomizer mounting member 42 and the tank mount 40. After the high-temperature-resistant material and the oil tank base 40 are integrally formed in an in-mold injection molding mode, the atomizing device 30 and the oil tank base 40 form an integral structure, and extra assembly is not needed.

As shown in fig. 6, although the atomizing device fixing member 42 and the oil tank base 40 are integrated, after the in-mold injection molding process is adopted, the atomizing device fixing member 42 may not be made of the same material as the oil tank base 40, but may be made of a material having high temperature resistance, rapid heat dissipation and high strength. Thus, the atomization device 30 can be quickly cooled, and the better structural stability can be kept under the condition of long-time high temperature, so that the atomization device fixing part 42 can reliably fix the atomization device 30 all the time.

The atomizer fixing member 42 is formed by 316 stainless steel surrounding the outer surface of the atomizer 30 by one circle, and the shape of the cross section surrounded by the atomizer fixing member 42 surrounding the outer surface of the atomizer 30 by one circle is matched with the shape of the cross section of the atomizer 30.

In the present embodiment, the atomization device 30 may be made of 316 stainless steel and integrally formed with the tank base 40 by means of in-mold injection molding. The atomizer mounting 42 may be an annular structure into which the atomizer 30 is snapped into place. In order to enable the atomizer fixing member 42 to reliably fix the atomizer 30, the present embodiment designs the shape of the cross section of the region surrounded by the annular structure to match the shape of the cross section of the outer surface of the atomizer 30. Thus, the inner wall of the atomization device fixing member 42 can be tightly attached to the outer surface of the atomization device 30 to fix the atomization device 30, and the atomization device 30 can rapidly dissipate heat through the atomization device fixing member 42.

Atomizing device 30 includes atomizing core 32 and cladding coating 31 on atomizing core 32 outer wall, atomizing device mounting 42 forms annular fender of enclosing for extending to atomizing end cover 50 direction by the terminal surface relative with oil hold 10 of oil hold base 40, enclose the accommodation space that becomes to be used for holding atomizing device 30 jointly with the terminal surface relative with oil hold 10 of fender and oil hold base 40, atomizing device 30 is located in the accommodation space, coating 31 is filled and is being enclosed the space department between fender and atomizing device 30.

When the atomizing device 30 is fixed on the oil tank base 40, the coating layer 31 is made to sufficiently fill the gap between the enclosure and the atomizing device 30 by the elasticity of the coating layer 31, so as to reliably fix the atomizing device 30 on the oil tank base 40.

In addition, the present embodiment further includes a conductive sheet 51, located inside the atomizing end cap 50, and integrally formed with the atomizing end cap 50, where the conductive sheet 51 is formed by extending an inner wall of the atomizing end cap 50 opposite to the atomizing device 30 in a direction of the atomizing device 30;

the conductive sheet 51 may be made of a metal having good conductivity. Since the conductive sheet 51 is located inside the atomizing end cap 50, it can be manufactured by an in-mold injection molding method. In order to improve the conductive capability of the conductive sheet 51, the size of the current conducted by the conductive sheet 51 can be improved by improving the cross-sectional area of the conductive sheet 51, and because the conductive sheet 51 is positioned inside the atomizing end cap 50 and does not need to penetrate through the atomizing end cap 50 from the outside to the inside of the atomizing end cap 50, the size of the conductive sheet is not limited, and the cross-sectional area can be set according to the current conduction requirement, so that the cross-sectional area is larger than the corresponding preset area.

The atomization end cap 50 electrically connects the electrode of the atomization device 30 located inside the atomization end cap 50 and the contact point contacting with the outer wall of the atomization end cap 50 through the conducting strip 51.

As shown in fig. 3 and 6, when the cigarette rod 200 and the cartridge 100 are assembled, the contact point of the cigarette rod 200 contacts the outer wall of the atomizing end cap 50 at the outside of the cartridge 100, while the electrode of the atomizing device 30 located inside the atomizing end cap 50 contacts the conductive sheet 51, and when the electricity is applied, the outer wall of the atomizing end cap 50 conducts the current to the inner wall of the atomizing end cap 50, then the current is conducted to the conductive sheet 51 integrally formed with the inner wall by the inner wall, and finally the current is conducted to the electrode of the atomizing device 30 contacting the conductive sheet 51 by the conductive sheet 51.

In order to form reliable electrical connection between the electrode of the atomizing device 30 and the contact point contacting with the outer wall of the atomizing end cap 50, the atomizing end cap 50 of the present embodiment is integrally a conductive body, the atomizing end cap 50 further includes a contact point contacting portion 53 integrally formed with the outer wall thereof, and the contact point contacting portion 53 is formed by protruding the outer wall of the atomizing end cap 50 to a preset height position in a direction opposite to the atomizing device 30.

Since the atomization cap 50 is an electrical conductor as a whole, current can be conducted from any region outside the atomization cap 50 to any region of the wall of the atomization cap 50 without penetrating the atomization cap 50 from outside to inside with other components. Compared with the pin needle in the prior art, the whole atomization end cover 50 serving as the electric conductor can increase the size of the conducted current at a low cost, so that the atomization effect of the atomization device 30 is remarkably improved. In order to allow the contact point of the tobacco rod 200 to securely contact the outer wall of the atomizing end cap 50. The outer surface of the atomizing end cap 50 facing the electrode of the cigarette rod 200 is provided with at least one convex part facing the contact point direction of the cigarette rod 200 at a position corresponding to the contact point, and the convex part and the outer surface of the atomizing end cap 50 facing the electrode of the cigarette rod 200 are kept at a certain height difference, so that the contact point of the cigarette rod 200 can be reliably contacted with the convex contact point contact part 53. In order to prevent the smoke from leaking from the atomizing end cap 50, the contact boss is formed integrally with the atomizing end cap 50, so that no gap is formed in the atomizing end cap 50 for assembling the components.

Since the conductive sheet 51 does not need to penetrate through the atomizing end cap 50 from the outside to the inside, the shape and size of the conductive sheet 51 are not easily limited. In this case, the area of the cross section of the conductive sheet 51 may be increased as needed, for example, the area of the cross section of the conductive sheet 51 may be limited to be larger than a predetermined area value. In order to ensure that the conductive sheet 51 can reliably contact with the electrode of the atomizing device 30, the conductive sheet 51 needs to have certain elasticity, and the shape and size of the conductive sheet 51 are not limited by other factors, so that the conductive sheet 51 can be relatively flat, that is, the width of the conductive sheet 51 can be properly increased under the condition that the cross-sectional area of the conductive sheet 51 is not reduced, the ratio of the width to the thickness of the conductive sheet 51 is larger than a certain set value, so that the elasticity of the conductive sheet 51 can be increased, and the conductive sheet 51 can reliably contact with the electrode of the atomizing device 30 by means of the elastic restoring force.

As shown in fig. 6 and 7, in order to ensure reliable contact between the conductive sheet 51 and the electrode of the atomization device 30, it is necessary to allow the conductive sheet 51 to be deformed largely without being damaged. Therefore, in this embodiment, a frustum-shaped reinforcing structure 511 is formed at one end of the conductive sheet 51 connected to the atomizing end cap 50, the opposite end is a free end, the cross-sectional area of the frustum body is gradually reduced from the atomizing end cap 50 toward the free end, and the ratio of the cross-sectional area of the connection portion of the frustum and the inner wall of the atomizing end cap 50 to the height of the frustum is smaller than a first threshold value.

In the present embodiment, the end of the conducting strip 51 contacting with the electrode of the atomizing device 30 is a free end which is not fixed with other components, so that the end of the conducting strip 51 contacting with the electrode can be freely deformed according to the height position of the electrode to adapt to the electrode at different positions, and reliable contact between the conducting strip 51 and the electrode can be ensured by adapting the position of the free end no matter how the height position of the electrode changes. Since the free end of the conductive plate 51 needs to be tightly abutted against the electrode, the bending moment applied to the root position where the conductive plate 51 is connected with the atomizing end cap 50 is the largest, and therefore, the reinforcing structure 511 is arranged at the root position. The reinforcing structure 511 is in a frustum shape, and the larger the cross-sectional area of the reinforcing structure 511 is near the joint of the inner walls of the atomizing end cap 50, the stronger the bending resistance is. The reinforcing structure 511 is gradually reduced along the direction of the free end by the inner wall of the atomizing end cover 50 and is transited to the size meeting the elastic requirement of the conducting strip 51, the transition is natural, and the condition of overlarge local stress is not easy to generate in the deformation process of the conducting strip 51. In order to ensure the strength of the reinforcing structure 511, the present embodiment may appropriately limit the ratio of the cross-sectional area of the connection between the frustum and the inner wall of the atomizing end cap 50 to the height of the frustum to ensure that the conductive sheet 51 does not generate structural damage at the connection with the inner wall of the atomizing end cap 50. In addition, the sectional area of the reinforcing structure 511 at the root of the conductive sheet 51 is increased, so that the magnitude of the conductive current of the conductive sheet 51 can be further increased.

In this embodiment, the conductive sheet 51 further includes a first extending section 512 formed by extending the reinforcing structure 511 toward the electrode direction of the atomizing device 30, a second extending section 513 formed by extending an end of the first extending section 512 opposite to the reinforcing structure 511 toward the electrode direction of the atomizing device 30, and a third extending section 514 formed by extending an end of the second extending section 513 opposite to the first extending section 512, where the extending direction of the first extending section 512 and a plane where an inner wall of the conductive sheet 51 formed by the atomizing end cap 50 forms a first preset intersection angle, the extending direction of the second extending section 513 and the extending direction of the first extending section 512 form a second preset intersection angle, the length of the second extending section 513 is greater than the preset length, and the third extending section 514 is an arc shape protruding toward the atomizing device 30.

The extending direction of the first extending section 512 and the plane perpendicular to the inner wall of the atomizing end cap 50 forming the conducting strip 51 form a first preset intersection angle, which is the included angle formed by the plane part of the first extending section 512 and the plane perpendicular to the inner wall. The extending direction of the second extending section 513 and the extending direction of the first extending section 512 form a second predetermined intersection angle, which is an included angle formed by a plane portion of the first extending section 512 and a plane portion of the second extending section 513.

The plane perpendicular to the inner wall of the first extension section 512 is inclined at a certain angle, and the electrode of the atomization device 30 is positioned right above the inner wall, so that the direction of the force applied by the electrode on the conductive sheet 51 is close to the direction perpendicular to the inner wall, and thus, when the second extension section 513 or the third extension section 514 of the conductive sheet 51 is in contact with the electrode of the atomization device 30, the stress direction of the first extension section 512 and the extension direction thereof also form a certain angle, so that the first extension section 512 can be bent at a larger angle after the free end is stressed, and the different heights of the electrode of the atomization device 30 can be fully adapted. Since the tail of the second extending section 513 or the third extending section 514 is a part which may contact with the electrode, and the rotation angle of the second extending section 513 affects the displacement of the second extending section 513 and the third extending section 514, the length of the second extending section 513 and the included angle between the extending direction of the second extending section 513 and the extending direction of the first extending section 512 are defined in this embodiment, so that the elastic coefficient of the conductive sheet 51 and the displacement of the second extending section 513 and the third extending section 514 can meet the requirements of different electrode positions. In addition, the cross-sectional area of the conductive sheet 51 is gradually reduced from the first extension section 512 to the third extension section 514, so that the magnitude of the bending moment applied to the conductive sheet 51 and the section is matched. Since the third extending section 514 is the section most likely to contact with the electrode, in this embodiment, the third extending section 514 is an arc shape protruding toward the atomizing device 30, so that the distance between each part of the third section and the electrode gradually changes, and when the third extending section 514 contacts with the electrode, the electrode can relatively slide along the protruding arc shape to a position where the electrode can well contact with the third extending section 514 in cooperation with the elastic deformation of the conducting strip 51.

Example 2

As shown in fig. 2 and fig. 3, the present embodiment is further improved on the basis of embodiment 1, in the present embodiment, a first condensate adsorbing member 70 is used for adsorbing condensate and/or smoke, the first condensate adsorbing member 70 abuts against an inner wall of the atomizing end cap 50 opposite to the atomizing device 30, and the inner wall of the atomizing end cap 50 opposite to the electrode is spaced from an end surface of the oil tank 10 facing the atomizing device 30 by a preset distance.

After the electronic cigarette is used for a period of time, the tobacco tar and the condensate in the cartridge 100 easily flow from the cartridge 100 to the circuit board of the electronic cigarette, and damage is caused to the circuit board. Therefore, in the embodiment, the first condensate adsorbing member 70 is disposed on the inner wall of the atomizing end cap 50 close to the electrode, and is used for adsorbing the condensate and the tobacco tar of the accessory, and isolating the area in the cartridge 100 where the condensate is generated from the circuit board in the electronic cigarette, so as to prevent the condensate from flowing into the circuit board of the electronic cigarette from the area in the cartridge 100 where the condensate is generated, and to remarkably prolong the service life of the electronic cigarette.

As shown in fig. 2 and 8, in the present embodiment, the cartridge 100 further includes a second condensate adsorbing member 80 closely attached to an end surface of the oil tank 10 facing the mouthpiece 20, a peripheral wall of the second condensate adsorbing member 80 abuts against an inner wall of the mouthpiece 20 for adsorbing the condensate and/or the smoke flowing to the mouthpiece 20, the cartridge 100 further includes a condensate blocking ring 11 for blocking the condensate on an outer wall of the oil tank 10 from flowing to the mouthpiece 20, and the condensate blocking ring 11 is an annular structure formed by extending from the end surface of the oil tank 10 facing the smoke suction port 21 of the mouthpiece 20 to the smoke suction port 21 of the mouthpiece 20.

The second condensate adsorbing member 80 may be made of high-density polyethylene or oil absorbent cotton.

Since the soot in the cargo tank 10 may flow into the smoking opening 21 from the gap between the cargo tank 10 and the inside of the mouthpiece 20 when the soot leaks, the second condensate adsorbing member 80 further includes an adsorbing layer for adsorbing the soot flowing toward the smoking opening 21 of the mouthpiece 20 in this embodiment. Since the second condensate adsorbing member 80 is located at a position between the opening of the cargo tank 10 and the smoke suction port 21, the adsorption layer provided on the second condensate adsorbing member 80 adsorbs the tobacco before the tobacco flows into the smoke suction port 21. The adsorption layer may be compounded on the second condensate adsorbing member 80 using a composite material. When the second condensate adsorbing member 80 uses high-density polyethylene or oil absorbent cotton, the entire second condensate adsorbing member 80 functions as an oil absorbing layer.

The outer surface of the second condensate adsorbing member 80 includes a first surface facing the mouthpiece 20 and a second surface facing the cargo tank 10, and the remaining surfaces are the peripheral walls of the second condensate adsorbing member 80. When the peripheral wall of the second condensate adsorbing member 80 abuts against the inner wall of the mouthpiece 20, the interior of the mouthpiece 20 is divided into two mutually isolated spaces, one of the spaces is communicated with the smoking opening 21 of the mouthpiece 20, and the other space includes the oil tank 10, the oil tank base 40, the atomizer and other parts which are easy to generate condensate. Due to the partition action of the second condensate adsorbing member 80, the condensate is blocked from entering the smoking opening 21 of the mouthpiece 20 outside the space communicating with the smoking opening 21. Therefore, when the condensate in the cartridge 100 flows to the end surface of the oil tank 10 facing the mouthpiece 20, the second condensate adsorbing member 80 can block the condensate, so as to prevent the condensate from flowing further toward the smoking opening 21 of the mouthpiece 20, and prevent the condensate in the cartridge 100 from flowing into the mouth of the user.

The mouthpiece 20 is in a shell shape, and a pressing structure for pressing the second condensate adsorbing member 80 against the end surface of the oil tank 10 facing the smoking opening 21 of the mouthpiece 20 toward the direction of the oil tank 10 is formed on the inner wall of the shell-shaped mouthpiece 20 opposite to the second condensate adsorbing member 80.

In order to improve the isolation effect of the second condensate adsorption part 80, a compressing structure is arranged inside the cigarette holder 20, and the structure compresses the second condensate adsorption part 80 on the end surface of the oil tank 10 facing the smoking opening 21 of the cigarette holder 20 towards the direction of the oil tank 10, so that the position of the second condensate adsorption part 80 is kept fixed, and the condensate leakage to the smoking opening 21 caused by the movement of the second condensate adsorption part 80 is avoided.

The compressing structure is a compressing plate formed by extending the inner wall of the shell-shaped cigarette holder 20 opposite to the second condensate adsorbing member 80 to the direction of the second condensate adsorbing member 80, and the compressing plate compresses the second condensate adsorbing member 80 on the end face of the oil tank 10 facing the smoking opening 21 of the cigarette holder 20. When the cartridge 100 is assembled, the second condensate adsorbing member 80 is pressed toward the cargo tank 10 by the pressing force of the mouthpiece 20, so that the second condensate adsorbing member can be closely attached to the end surface of the cargo tank 10. In specific implementation, the pressing plates comprise a first pressing plate and a second pressing plate which are respectively positioned at two sides of the smoking port 21. The pressure strip is also in close contact with the second condensate adsorbing member 80 while pressing the second condensate adsorbing member 80 so that the pressure strip and the second condensate adsorbing member 80 can be formed as a single unit to form a separate structure that substantially separates the area near the smoking opening 21 of the mouthpiece 20 that communicates with the smoking opening 21 from the other areas inside the cartridge 100.

As shown in fig. 9, the condensate baffle ring 11 is located at a position directly below the smoking port 21. The embodiment arranges the condensate baffle ring 11 towards the smoking opening 21 of the cigarette holder 20, and the condensate baffle ring 11 can effectively shield the area of the oil tank 10 close to the cigarette holder 20, so as to prevent condensate from flowing into the cigarette holder 20 from the area.

The outer wall of the condensate baffle ring 11 is formed with an inclined plane which forms a preset included angle with the end surface of the oil tank 10 facing the cigarette holder 20. The outer wall of the condensate retaining ring 11 is set to be an inclined plane, so that the condensate can slide along the inclined plane, and the condensate is prevented from being accumulated on the retaining ring.

In addition, in this embodiment, a preset distance is kept between the inner wall of the atomizing end cover 50 close to the electrode and the end surface of the oil tank 10 facing the atomizing device 30, and by setting a suitable distance, the distance from the part of the cartridge 100 where condensate is easily generated to the circuit board can be increased, so that the probability of the condensate flowing into the circuit board is reduced.

Example 3

The embodiment further improves the flue on the basis of the embodiment 1. In this embodiment, atomizing end cover 50 is equipped with air inlet 52, the flue includes first flue 61 and second flue 62 and first flue 61, first flue 61 be located the oil hold 10 with the one side that smoking mouth 21 is relative, atomizing device 30 with one side that oil hold 10 is relative is located first flue 61, second flue 62 is located one side that atomizing device 30 is relative with air inlet 52, the air current flow direction of second flue 62 and the air current flow direction of first flue 61 become a predetermined contained angle.

The structure form of the linear flue in the prior art is abandoned in the embodiment, and the flue is divided into the first flue 61 and the second flue 62 which form a certain included angle with each other. Wherein the first flue 61 is located on the opposite side of the cargo tank 10 from said smoking opening 21. Because the side of the atomizing core opposite to the oil tank 10 is positioned in the first flue 61, the air flows into the first flue 61 from the air inlet 52 and directly flows into the lower surface of the atomizing core, and is fully contacted with the tobacco tar in the first flue 61, so that the atomized smoke can be fully combusted. Since the second flue 62 is located on the opposite side of the atomizing device 30 from the air inlet 52, the second flue 62 is far away from the tank 10 and the communication position of the tank 10 and the atomizing device 30, and forms an included angle with the first flue 61, so that the tobacco tar can be sufficiently mixed and atomized in the first channel and enter the second flue 62 after being combusted, and the tobacco tar in the tank 10 is difficult to leak into the second flue 62 from the communication position of the atomizing device 30 and the tank 10.

One end of the second flue 62 is communicated with the smoke suction port 21, the other opposite end is communicated with one end of the first flue 61 opposite to the air inlet 52, and the first flue 61 is used for enabling air flowing in from the air inlet 52 to fully combust with the atomized tobacco tar in the first flue 61 and then flow to the smoke suction port 21 from the second flue 62.

The two ends of the first flue 61 cross over the atomization device, wherein the air inlet and the second flue 62 are respectively positioned at two ends of the first flue 61, so that the second flue 62 and the air inlet are staggered, and the tobacco tar is not easy to leak into the second flue 62.

As shown in fig. 3, in the present embodiment, the oil tank base 40 and the oil tank 10 are formed with a weld line ultrasonic welding structure that hermetically connects the oil tank base 40 on the flue and the oil tank 10, the weld line ultrasonic welding structure includes a first ultrasonic welding structure that includes a first annular protrusion 41 formed by extending a surface of the oil tank base 40 that is connected to the oil tank 10 in a direction toward the oil tank 10 and a first annular groove 12 formed by recessing a surface of the oil tank 10 that is connected to the oil tank base 40 in a direction opposite to the oil tank base 40, and the first annular protrusion 41 is inserted into the first annular groove 12 and connected by ultrasonic welding.

The annular welding area may be any one of a circular shape, an elliptical ring shape, a rectangular shape, and the like, which can form a closed area.

In order to improve the sealing effect, in this embodiment, one end of the first annular protrusion 41 facing the first annular groove 12 is formed with a wedge structure ultrasonically welded to the first annular groove 12, the wedge structure is formed by a first welding surface and a second welding surface intersecting at a preset angle, the oil tank 10 is formed with a first column extending from the end surface of the oil tank 10 facing the oil tank base 40 to the end surface of the oil tank 10 facing the smoke suction port 212, the first column includes a hollow structure for forming a flue, and the first annular groove 12 is formed in the end surface of the first column facing the oil tank base 40. In order to form a flue with a stable structure, the oil tank 10 of the present embodiment is provided with a column in the axial direction, which is the same as the flow direction of the air flow in the flue, and the middle of the column is made into a hollow structure, and the hollow structure is used as the flue.

On one hand, the wedge-shaped structure is easier to be embedded into the first annular groove 12, so that the positioning during assembly can be facilitated, and the subsequent welding effect is improved and guaranteed. On the other hand, the wedge-shaped structure consists of a first welding surface and a second welding surface, and can form an inner annular welding area and an outer annular welding area by matching with the first annular groove 12, so that two-layer sealing can be realized on the flue, and the sealing reliability can be increased by times by slightly changing the original structure. The angle at which the first and second weld faces meet may be determined according to the sealing effect.
