Example 1:

as shown in fig. 1 and 2, the present embodiment provides an electronic cigarette cartridge 100. 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.

As shown in fig. 2 and 3, the electronic cigarette cartridge 100 of the present embodiment forms an electrical connection between a contact point contacting the outer wall of the end cap 50 and an electrode of the atomizing device 30 located inside the end cap 50 through the end cap 50 and the conductive sheet 51 formed integrally with the end cap 50 inside the end cap 50. The current of the power supply can be conducted from the outside of the cartridge 100 to the electrode of the atomizing device 30 of the cartridge 100 inside the cartridge 100, and the conducting mode does not need any part to penetrate through the end cover 50 from outside to inside, so that the end cover 50 does not need to form a structure which is easy to leak the tobacco tar, such as a through hole, and the leakage of the tobacco tar from the structure which is electrically connected with the end cover 50 is effectively avoided. And the conduction mode of this embodiment does not need to install pin needle, consequently has saved the technological process according to pin needle in product production, makes production efficiency obtain showing the improvement. In addition, as the end cover 50 does not need to be penetrated, the shape and the size of the conducting strip 51 are not limited by a connecting structure, the cross-sectional area of the conducting strip 51 can be increased to a greater extent, and the conducting strip 51 can conduct larger current.

As shown in fig. 2 and 3, the electronic cigarette cartridge 100 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;

wherein the atomization device 30 comprises an atomization core and a coating layer coated on the outer wall of the atomization core. In the embodiment, the atomization core is preferably a ceramic atomization core with good high-temperature resistance. The atomizing core is provided with a heating component, and the heating component generates heat for atomizing the tobacco tar after the atomizing core is powered on.

The flue guides the smoke formed after the tobacco tar is atomized by the atomization device 30 to flow to the smoke suction port 21;

the oil sealing cover 40 is connected with one end of the oil tank 10 close to the atomizing device 30;

wherein the oil-sealing cover 40 is used for sealing the oil tank 10 so as to prevent the smoke oil in the oil tank 10 from leaking out of the oil tank 10.

An end cover 50 covering the side of the oil seal cover 40 facing the atomizing device 30;

the conducting strip 51 is positioned inside the end cover 50 and integrally formed with the end cover 50, and the conducting strip 51 is formed by extending the inner wall of the end cover 50 opposite to the atomizing device 30 towards 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 end cap 50, it can be manufactured by in-mold injection molding. 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 the conductive sheet 51 is located inside the end cover 50 and does not need to penetrate from the outside of the end cover 50 to the inside of the end cover 50, so that 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 end cap 50 electrically connects the electrodes of the atomizing device 30 located inside the end cap 50 to contacts contacting the outer wall of the end cap 50 through conductive tabs 51.

As shown in fig. 3 and 4, when the cigarette rod 200 and the cartridge 100 are assembled, the contact of the cigarette rod 200 contacts the outer wall of the end cap 50 at the outside of the cartridge 100, and the electrode of the atomizer 30 located inside the end cap 50 contacts the conductive sheet 51, and when the current is applied, the outer wall of the end cap 50 conducts the current to the inner wall of the 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 atomizer 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 end cap 50, the end cap 50 of the present embodiment is integrally formed as a conductive body, the 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 end cap 50 to a predetermined height position in a direction opposite to the atomizing device 30.

Since the end cap 50 is an electrical conductor throughout, current can be conducted from any area outside the end cap 50 to any area of the wall of the end cap 50 without the need for other components to pass through the end cap 50 from the outside to the inside. Compared with the pin needle in the prior art, the whole 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 points of the tobacco rod 200 to securely contact the outer wall of the end cap 50. The outer surface of the end cap 50 facing the electrode of the cigarette rod 200 is provided with at least one convex part facing the contact of the cigarette rod 200 at a position corresponding to the contact, and the convex part and the outer surface of the end cap 50 facing the electrode of the cigarette rod 200 are maintained at a certain height difference, so that the contact of the cigarette rod 200 can be reliably contacted with the convex contact part 53. To avoid oil leakage from the end cap 50, the contact boss is formed integrally with the end cap 50 so that no gap is formed in the end cap 50 for the assembly of the various components.

Since the conductive sheet 51 does not need to penetrate the 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. 4 and 5, 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, one end of the conductive sheet 51 connected to the end cap 50 is formed with a frustum-shaped reinforcing structure 511, the opposite end is a free end, the cross-sectional area of the frustum is gradually reduced from the end cap 50 toward the free end, and the ratio of the cross-sectional area at the junction of the frustum and the inner wall of the end cap 50 to the height of the frustum is smaller than a first threshold.

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 sheet 51 needs to be tightly pressed against the electrode, the bending moment applied to the root position where the conductive sheet 51 is connected with the end cover 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 end cap 50, the stronger the bending resistance is. The reinforcing structure 511 is gradually reduced from the inner wall of the end cover 50 along the direction of the free end and transits 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 junction between the frustum and the inner wall of the end cap 50 to the height of the frustum to ensure that the conductive sheet 51 does not generate structural damage at the junction with the inner wall of the 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 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 first extension section 512 extends in a first predetermined angle with respect to a plane perpendicular to the inner wall of the end cap 50 forming the conductive sheet 51, which is an angle formed by a plane portion of the first extension 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 end cap 50 opposite to the atomizing device 30, and the inner wall of the 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. For this reason, in the present embodiment, the first condensate adsorbing member 70 is disposed on the inner wall of the end cap 50 on the side close to the electrode, and is used for adsorbing the condensate and the tobacco tar of the accessory, and isolating the region 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 from the region in the cartridge 100 where the condensate is generated from the circuit board in the electronic cigarette, and thus, the service life of the electronic cigarette is significantly prolonged.

As shown in fig. 2 and fig. 6, in the present embodiment, the cartridge 100 further includes a second condensate adsorbing member 80 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 smoking opening 21 of the mouthpiece 20 to the smoking opening 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 seal cover 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.

Specifically, 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, the inner wall of the end cover 50 close to the electrode is spaced from the end surface of the oil tank 10 facing the atomizing device 30 by a predetermined distance, and by setting a suitable distance, the distance from the part of the cartridge 100 where the condensate is likely to be generated to the circuit board can be increased, thereby reducing the probability of the condensate flowing into the circuit board.

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.
