In case of conflict, the various features of the embodiments and examples of the present invention may be combined with each other and are within the scope of the present invention.

Example 1:

as shown in fig. 1 and 2, the present embodiment provides a cartridge in which an atomizing core is integrally formed with a tank base. 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 core 30 of the cartridge 100 and the power supply provides electrical power to the atomizing core 30 of the cartridge 100, which the atomizing core 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 where the cartridge 100 has atomised the wick 30. 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, in the present embodiment, the tank base 40 and the atomizing core 30 are made into an integrated structure by an in-mold injection molding method, and the atomizing core 30 and the tank base 40 do not need to be installed after being manufactured respectively, so that the flow of assembling and fixing the atomizing core 30 is saved, and the condition of inaccurate assembling position due to low assembling precision is avoided. And the atomizing core 30 and the oil tank base 40 can not generate assembly clearance, thereby thoroughly avoiding the situation that the tobacco tar in the oil tank 10 leaks out from the assembly clearance between the atomizing core 30 and the oil tank base 40. And the atomizing core 30 of this embodiment extends to and directly heats the tobacco tar in the oil tank 10, makes atomizing core 30 can soak in the tobacco tar all the time when heating, has avoided atomizing core 30 to do under the condition that does not have the tobacco tar or the tobacco tar is less dry combustion and causes the damage of cigarette 100. In addition because the atomizing core 30 of this embodiment can directly establish the infiltration and heat the tobacco tar in the tobacco tar, 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 atomizing core 30, 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 in which the atomizing core and the tank base are integrally formed according to the present embodiment includes:

an oil tank 10 for storing tobacco tar;

the oil tank 10 serves in this embodiment as an oil reservoir for the cartridge 100. 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;

the mouthpiece 20 is fitted to the exterior of the tank 10 as part of the outer shell of the cartridge 100, and the user inhales with the mouthpiece 20 contained in the mouth during use, and the atomised smoke passes from the mouthpiece 20 through the mouthpiece 21 into the user's mouth.

An oil tank base 40 connected to an end of the oil tank 10 opposite to the smoke suction port 21;

after the tobacco tar is injected into the cargo tank 10, the opening of the cargo tank 10 is closed with the cargo tank base 40.

The flue guides the smoke formed by the atomization of the tobacco tar by the atomization core 30 to flow to the smoke suction port 21;

the atomizing core 30 is used for atomizing the smoke oil, the atomizing core 30 is integrally formed with the oil tank base 40 through in-mold injection, one end of the atomizing core 30, which faces the oil tank 10, extends into the oil tank 10, so that the ceramic atomizing core 30 heats the smoke oil in the oil tank 10, and the other opposite end extends to one side, opposite to the oil tank 10, of the oil tank base 40;

and the atomizing end cover 50 is covered on one side of the oil tank base 40 facing the atomizing core 30.

The in-mold injection molding is an existing integrated forming process, and the oil tank base 40 and the atomizing core 30 made of different materials can form an integrated integral structure by adopting the process. The atomizing core 30 generates heat to atomize the soot after the power is turned on, so that the atomizing core 30 itself has a high temperature. When the oil tank base 40 and the atomizing core 30 form an integrated atomizing core 30 with an integral structure, heat of the atomizing core 30 is directly transferred to the oil tank base 40, and in order to avoid the damage of the smoke cartridge 100 caused by the high-temperature deformation of the oil tank base 40, the oil tank base 40 can be formed by injection molding of high-temperature-resistant plastics. For example, PEEK plastic with good high temperature resistance may be selected, and materials that can reach high temperature, such as polyphenylene sulfide (PPS), arylsulfone (PAR), POB, aminoplast, polyborodiphenylsiloxane (PBP), Polybenzimidazole (PBI), and the like, may also be selected as materials for manufacturing the oil tank base 40. The particular materials may be selected based on the performance requirements of the cartridge 100 and are not limited herein.

As shown in fig. 3 and 4, since the tank base 40 and the atomizing core 30 in the embodiment are an integrated integral structure, the atomizing core 30 and the tank base 40 do not need to be installed after being manufactured respectively, so that the assembly process of the atomizing core 30 is saved, and the condition that the assembly position is inaccurate due to low assembly precision is also avoided. And the atomizing core 30 and the oil tank base 40 can not generate assembly clearance, thereby thoroughly avoiding the situation that the tobacco tar in the oil tank 10 leaks out from the assembly clearance between the atomizing core 30 and the oil tank base 40. And adopt the integral structure of this embodiment, atomizing core 30 can extend to directly heat the tobacco tar in the oil tank 10, makes atomizing core 30 can soak in the tobacco tar all the time when heating, has avoided atomizing core 30 to do under the circumstances that does not have the tobacco tar or the tobacco tar is less dry combustion and causes the damage of cigarette 100. In addition because the atomizing core 30 of this embodiment can directly establish the infiltration and heat the tobacco tar in the tobacco tar, 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 atomizing core 30, 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 order to further improve the atomization effect, in this embodiment, the atomization end cover 50 is provided with an air inlet 52, the flue includes a first flue 61, a second flue 62 and the first flue 61, the first flue 61 is located on one side of the oil tank 10 opposite to the smoke suction port 21, the atomization core 30 is located in the first flue 61 on one side of the oil tank 10 opposite to the oil tank, the second flue 62 is located on one side of the atomization core 30 opposite to the air inlet 52, and the airflow flowing direction of the second flue 62 and the airflow flowing direction of the first flue 61 form a preset included 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 core 30 from the air inlet 52, the second flue 62 is far away from the oil tank 10 and the communication position of the oil tank 10 and the atomizing core 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 oil tank 10 is difficult to leak into the second flue 62 from the communication position of the atomizing core 30 and the oil 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 atomizing core, wherein the air inlet and the second flue 62 are respectively positioned at the two ends of the first flue 61, so that the second flue 62 and the air inlet are staggered with each other, and the tobacco tar is not easy to leak into the second flue 62.

Example 2

As shown in fig. 5, in the present embodiment, the mouthpiece 20 further includes an inner layer 22 formed with a smoking opening 21, the inner layer 22 is formed by a middle portion of the outer shell of the mouthpiece 20 being recessed towards the inside of the mouthpiece 20, and the smoking opening 21 is located on the inner layer 22 towards one end of the flue.

In this embodiment, the inner layer 22 is formed after the middle portion of the cartridge 100 is recessed inwardly, and the inner layer 22 thus formed is wrapped in the outer wall of the mouthpiece 20. In use by a user, smoke only flows through the inner layer 22 of the mouthpiece 20. While the inner layer 22 through which the smoke passes directly is wrapped in the outer wall of the mouthpiece 20 and does not come into direct contact with the user. When the user uses the cigarette holder, the user only needs to hold the outer wall of the cigarette holder 20. Therefore, only the outer wall of the cigarette holder 20 is in direct contact with the mouth of a user when the electronic cigarette is used by the user, so that the electronic cigarette is not scalded by high temperature generated by smoke, and the safety of the electronic cigarette is remarkably improved. The inner layer 22 is formed by recessing the top of the mouthpiece 20 toward the atomizer to a certain depth, and the smoking opening 21 of the mouthpiece 20 is located at the end facing the flue. Therefore, the inner layer 22 is far away from one end of the mouth of a user, so that the heat of smoke can be effectively prevented from being conducted to the contact position between the mouth of the user and the cigarette holder 20, and the user can be prevented from being scalded.

In addition, in the embodiment, a condensate blocking structure is arranged inside the flue, and the condensate blocking structure is formed by extending the inner wall of the flue along the radial direction of the flue.

When the electronic cigarette is used, the water in the smoke is liquefied to form condensate after being cooled. The condensate easily flows along the inner wall of the flue to the smoke suction port 21, causing the user to suck the condensate. This embodiment thus provides a condensate barrier 63 on the inner wall of the flue, which may be a cylindrical protrusion extending a length from the inner wall of the cartridge 100 in the radial direction of the flue. When the condensate in the cartridge 100 flows along the inner wall of the flue, the condensate blocking structure 63 can block the condensate, so as to prevent the condensate from finally flowing to the position of the oil suction port. The cylindrical raised condensate blocking structures 63 can be arranged at intervals along the path through which the flue gas flows, and multiple blocking is formed in the process that the condensate flows to the smoke suction port 21, so that the probability that the condensate finally flows to the smoke suction port 21 is greatly reduced.

In addition, the atomizing device further comprises a conducting strip 51 which is positioned inside the atomizing end cover 50 and integrally formed with the atomizing end cover 50, wherein the conducting strip 51 is formed by extending the inner wall of the atomizing end cover 50 opposite to the atomizing core 30 in the direction of the atomizing core 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 core 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 7, 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 core 30 located inside the atomizing end cap 50 contacts the conductive sheet 51, and after 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 core 30 contacting the conductive sheet 51 by the conductive sheet 51.

In order to form reliable electrical connection between the electrode of the atomizing core 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 the direction opposite to the atomizing core 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 core 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 core 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, i.e., the width of the conductive sheet 51 is 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 core 30 by means of 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 atomizing core 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 embodiment, the end of the conducting strip 51 contacting with the electrode of the atomizing core 30 is a free end which is not fixed with other parts, 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 the reliable contact of the conducting strip 51 and the electrode can be ensured by the adaptive change of 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 core 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 core 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 a first preset intersection angle is formed between 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 is located, a second preset intersection angle is formed between the extending direction of the second extending section 513 and the extending direction of the first extending section 512, 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 core 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 atomizing core 30 is positioned right above the inner wall, so that the direction of the force applied by the electrode on the conducting strip 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 conducting strip 51 is in contact with the electrode of the atomizing core 30, the stress direction of the first extension section 512 is also at a certain angle with the extension direction thereof, so that the first extension section 512 can be bent at a larger angle after the free end is stressed, and the electrode of the atomizing core 30 can be fully adapted to different heights of the electrode. 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 core 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 3

As shown in fig. 2 and 3, in the present embodiment, the first condensate adsorbing member 70 is configured to adsorb condensate and/or soot, the first condensate adsorbing member 70 abuts against an inner wall of the atomizing end cap 50 opposite to the atomizing core 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 core 30 by a predetermined 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, 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 condensate and/or tobacco tar flowing to the mouthpiece 20, the cartridge 100 further includes a condensate blocking ring 11 for blocking 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 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.

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 core 30, and by setting a proper 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.
