Description

TECHNICAL FIELD

Embodiments of this application relate to the field of atomization technologies, and specifically, to an aerosol generating device.

BACKGROUND

Aerosol generating devices are configured to generate aerosols for users to inhale.
An aerosol generating device includes an atomizer and an additional e-liquid tank. An atomization core in the atomizer can absorb an aerosol generating substrate and convert the aerosol generating substrate into aerosols.

In related technologies, the additional e-liquid tank is in fluid communication with the atomizer. As a result, an excessive amount of aerosol generating substrates flows into the atomizer, and consequently the atomization core is at least partially directly immersed in the aerosol generating substrate.

It should be understood that these orientation terms are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that a device or an element must have a specific orientation, must be constructed and operated in a specific orientation, and therefore cannot be understood as limitation on the embodiments of the present invention.
An embodiment of this application provides an aerosol generating device for generating aerosols by heating an aerosol generating substrate or the like for users to inhale.
Referring to FIG. 1 to FIG. 4, FIG. 12, and FIG. 13, the aerosol generating device includes an atomizer 10 and an additional e-liquid tank 20.
The atomizer 10 includes an atomization component 11 and a first liquid storage component 12, where the atomization component 11 includes an air outlet channel 10b and a main storage cavity 10a, the air outlet channel 10b is isolated from the main storage cavity 10a, the air outlet channel 10b extends in a first direction, an outlet of the air outlet channel 10b is connected to the outside of the aerosol generating device, and the first liquid storage component 12 is at least partially located in the main storage cavity 10a.
An outlet end of the air outlet channel 10b can be directly used as a suction nozzle or connected to a separate suction nozzle. The additional e-liquid tank 20 is provided with an additional storage cavity 20a and a fluid channel 20b, where the fluid channel 20b is configured to connect the additional storage cavity 20a to the main storage cavity 10a, and the fluid channel 20b is located on a side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction.
The atomization component 11 includes an atomization core 111, and the atomization core 111 is configured to absorb an aerosol generating substrate in the main storage cavity 10a and convert the aerosol generating substrate into aerosols through heating or other methods.
The air outlet channel 10b is configured to discharge aerosols formed by the atomizer 10. When a user inhales aerosols, the aerosols enter the mouth of the user through the outlet of the air outlet channel 10b.
The air outlet channel 10b and the main storage cavity 10a are separated from each other, so that the aerosol generating substrate in the main storage cavity 10a cannot enter the air outlet channel 10b and leak.
The first liquid storage component 12 is provided with pores to store at least a part of the aerosol generating substrate in the main storage cavity 10a through capillary action. The first liquid storage component 12 is in fluid communication with the atomization component 11 to allow the aerosol generating substrate to flow from one to the other. A specific manner of achieving fluid communication between the first liquid storage component and the atomization component is not limited, for example, the first liquid storage component and the atomization component are in direct contact with each other, or a channel is provided between the first liquid storage component and the atomization component, to allow fluid to pass through the channel to come into contact with the first liquid storage component and the atomization component.
After the first liquid storage component 12 comes into contact with the aerosol generating substrate, the aerosol generating substrate can be absorbed by the first liquid storage component 12 and stored in a space of the pores through capillary action. At least some of the pores are connected to each other, so that the aerosol generating substrate can pass through the first liquid storage component 12 and be transported to the atomization core 111 of the atomization component 11 in fluid communication with the first liquid storage component 12.
The additional storage cavity 20a can store a specific amount of aerosol generating substrates. In a status in which the main storage cavity 10a is connected to the additional storage cavity 20a through the fluid channel 20b, the aerosol generating substrate in the additional storage cavity 20a can enter the main storage cavity 10a to supplement an amount of aerosol generating substrates in the main storage cavity 10a, so that the atomizer 10 can supply aerosols for a longer time.
The fluid channel 20b is located on the side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction. That is, an additional connecting opening 20c formed when the fluid channel 20b communicates with the additional storage cavity 20a is located on a wall of the side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction.
It should be noted that the wall of the side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction is a wall of a part of space close to the outlet of the air outlet channel 10b among two parts of space separated by a perpendicular bisector of a connecting line formed between two points with the largest distance from each other in the first direction in the additional storage cavity 20a.
When a user inhales aerosols, the first direction is roughly the vertical direction, the outlet of the air outlet channel 10b faces upwards, the additional connecting opening 20c is located on a top wall of the additional storage cavity 20a away from the ground, and the aerosol generating substrate in the additional storage cavity 20a tends to flow and accumulate towards a space of a side of the additional storage cavity 20a close to the ground under the action of gravity.
According to the aerosol generating device in the embodiments of this application, on the one hand, the first liquid storage component 12 is arranged to first absorb the aerosol generating substrate entering the main storage cavity 10a, and then release the aerosol generating substrate to the atomization component 11, which helps limit a speed of supplementing the aerosol generating substrate to the atomization component 11 and reduce the probability that the atomization component 11 is at least partially immersed in the aerosol generating substrate and consequently taste of aerosols inhaled by users is affected. On the other hand, during inhalation by users, due to the impact of gravity, it is difficult for the aerosol generating substrate in the additional storage cavity 20a to enter the fluid channel 20b and then enter the main storage cavity 10a, so that the atomization component 11 mainly consumes the aerosol generating substrate in the main storage cavity 10a. Therefore, it helps control the aerosol generating speed of the atomization component 11, and helps reduce the probability that the atomization component 11 is at least partially immersed in the aerosol generating substrate and consequently taste of aerosols inhaled by users is affected.
It can be understood that, when the user does not use the aerosol generating device, by inverting the aerosol generating device, the outlet of the air outlet channel 10b can face downwards, the additional connecting opening 20c is located on a bottom wall of the additional storage cavity 20a close to the ground, and the aerosol generating substrate can enter the fluid channel 20b and then supplement the main storage cavity 10a.
It can be understood that the pores of the first liquid storage component 12 can be macroscopic pores that can be recognized by naked eyes, or microscopic pores that cannot be recognized by naked eyes, as long as the aerosol generating substrate can be absorbed through capillary action and airflow is allowed to pass.
In some embodiments, referring to FIG. 3 and FIG. 4, the additional connecting opening 20c formed when the fluid channel 20b communicates with the additional storage cavity 20a is located on the wall of the side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction.
This better helps reduce the probability that the aerosol generating substrate in the additional storage cavity 20a enters the fluid channel 20b and then enters the main storage cavity 10a.
It should be noted that the wall of the side of the additional storage cavity 20a close to the outlet of the air outlet channel 10b in the first direction is a wall of a part of space close to the outlet of the air outlet channel 10b among two parts of space separated by a perpendicular bisector of a connecting line formed between two points with the largest distance from each other in the first direction in the additional storage cavity 20a, and the wall is farthest from the perpendicular bisector in the first direction. In addition, an extension direction of a surface of the wall is not parallel to the first direction.
A specific form of the first liquid storage component 12 is not limited, such as fiber structures woven and twisted from cotton wool, sponge, polyester, nylon, and other chemical fibers, or porous materials such as ceramics.
It can be understood that a material of the aerosol generating substrate relative to the first liquid storage component 12 is a wetting liquid, so that the aerosol generating substrate can be adhered or absorbed to the first liquid storage component 12.
In some embodiments, referring to FIG. 3 and FIG. 4, in a second direction, at least part of the main storage cavity 10a is located on a side of the additional storage cavity 20a, and the first direction intersects with the second direction.
This helps reduce the overall contour size formed by the atomizer 10 and the additional e-liquid tank 20 in the first direction while the size of the air outlet channel 10b in the first direction is kept unchanged.
In some embodiments, the first direction and the second direction are perpendicular to each other.
In some embodiments, referring to FIG. 3 and FIG. 4, the atomization component 11 further includes a main channel 10c, and the main channel 10c is connected to the fluid channel 20b and the main storage cavity 10a.
In some embodiments, referring to FIG. 4, the main channel 10c is located on a side of the main storage cavity 10a in the second direction. The main channel 10c is connected to the main storage cavity 10a and a main connecting opening 10d is formed in a connection position. The main connecting opening 10d is located on a side of the main storage cavity 10a close to the outlet of the air outlet channel 10b in the first direction.
That the main channel 10c is located on a side of the main storage cavity 10a in the second direction refers to that the main channel 10c and the main storage cavity 10a are arranged in the second direction.
In this way, when the outlet of the air outlet channel 10b faces downwards, this helps the aerosol generating substrate entering the main channel 10c flow directly into the main storage cavity 10a in the horizontal direction, thereby helping improve the efficiency of supplementing the aerosol generating substrate into the main storage cavity 10a.
In some embodiments, referring to FIG. 4 and FIG. 9, the first liquid storage component 12 at least partially covers the main connecting opening 10d.
This helps the aerosol generating substrate be absorbed by the first liquid storage component 12 more quickly after flowing out of the main channel 10c, reducing the probability that the atomization core 111 is directly immersed in the aerosol generating substrate. In some embodiments, referring to FIG. 3 and FIG. 4, the main channel 10c includes a first sub-channel 10ca and a second sub-channel 10cb, the atomization component 11 includes a sealing cover 1131 and a mounting shell 1132, a first mounting groove 1132a is provided in the mounting shell 1132, one side of the first mounting groove 1132a in the first direction is open, a wall opposite to the opening has an opening of the second sub-channel 10cb, the sealing cover 1131 covers an open position of the first mounting groove 1132a, so that the wall of the first mounting groove 1132a and the sealing cover form the first sub-channel 10ca, and the first sub-channel 10ca is connected to the second sub-channel 10cb.
The main channel 10c is formed by combining the sealing cover 1131 and the mounting shell 1132.
The sealing cover 1131 can be made of an elastic material, to help improve the sealing performance of the main channel 10c.
The first mounting groove 1132a is open in the first direction, and the second sub-channel 10cb extends in the first direction, to help form the first mounting groove 1132a and the second sub-channel 10cb in one-off effort through draft in the first direction.
In some embodiments, referring to FIG. 4, the fluid channel 20b extends in the first direction to connect the main channel 10c to the additional storage cavity 20a, so that aerosols can directly enter the main channel 10c under the action of gravity.
In some embodiments, referring to FIG. 12 and FIG. 13, the additional storage cavity 20a is located on a side of the main storage cavity 10a away from the outlet of the air outlet channel 10b in the first direction.
In this way, when the outlet of the air outlet channel 10b faces downwards, the main storage cavity 10a is at least partially located below the additional storage cavity 20a, so that the aerosol generating substrate in the additional storage cavity 20a can directly flow downwards into the main storage cavity 10a under the action of gravity, thereby helping improve the efficiency of supplementing the aerosol generating substrate to the main storage cavity 10a.
It can be understood that when a user continuously inhales aerosols, the aerosol generating substrate in the main storage cavity 10a is rapidly consumed, which can easily cause the risk of dry burning of the atomization component 11.
In some embodiments, referring to FIG. 13 to FIG. 16, the additional e-liquid tank 20 includes a housing component 21 and a second liquid storage component 25, the additional storage cavity 20a and the fluid channel 20b are located in the housing component 21, at least one of the additional storage cavity 20a and the fluid channel 20b is provided with the second liquid storage component 25, in a status in which the main storage cavity 10a is connected to the additional storage cavity 20a, the first liquid storage component 12 is in fluid communication with the second liquid storage component 25, and capillary attraction of the first liquid storage component 12 to an aerosol generating substrate is not less than capillary attraction of the second liquid storage component 25 to the aerosol generating substrate.
After the second liquid storage component 25 comes into contact with the aerosol generating substrate, the aerosol generating substrate can be absorbed by the second liquid storage component 25 and stored in a space of the pores through capillary action. At least some of the pores are connected to each other, so that the aerosol generating substrate can pass through the second liquid storage component 25 to come into contact with the first liquid storage component 12.
Because the capillary attraction of the first liquid storage component 12 to the aerosol generating substrate is not less than the capillary attraction of the second liquid storage component 25 to the aerosol generating substrate, the aerosol generating substrate in the second liquid storage component 25 can flow towards the first liquid storage component 12.
In this way, even if the outlet of the air outlet channel 10b keeps facing upwards in the aerosol generating device, the second liquid storage component 25 can still transfer the aerosol generating substrate to the first liquid storage component 12, to help alleviate dry burning of the atomizer 10. In addition, the aerosol generating substrate in the additional storage cavity 20a is supplied to the atomization core 111 through the second liquid storage component 25 and the first liquid storage component 12, which can effectively control an amount of the aerosol generating substrate supplied to the atomization core 111 and reduce the probability that the aerosol generating substrate leaks from the atomization core 111.
In some embodiments, the second liquid storage component 25 is provided only in the fluid channel 20b. In some embodiments, the second liquid storage component 25 is provided in both the additional storage cavity 20a and the fluid channel 20b.
A specific form of the second liquid storage component 25 is not limited, such as fiber structures woven and twisted from cotton wool, sponge, polyester, nylon, and other chemical fibers, or porous materials such as ceramics.
A specific manner of implementing that the capillary attraction of the first liquid storage component 12 to the aerosol generating substrate is not less than the capillary attraction of the second liquid storage component 25 to the aerosol generating substrate is not limited. For example, the first liquid storage component 12 and the second liquid storage component 25 are made of the same material, and the average volume of pores in the first liquid storage component 12 is smaller than the average volume of pores in the second liquid storage component 25, so that the capillary attraction of the first liquid storage component 12 to the aerosol generating substrate is greater than the capillary attraction of the second liquid storage component 25 to the aerosol generating substrate.
In some embodiments, referring to FIG. 16, one end of the second liquid storage component 25 in the first direction abuts against a wall of a side of the additional storage cavity 20a away from the main storage cavity 10a, and another end of the second liquid storage component abuts against the first liquid storage component 12.
In this way, on the one hand, both the wall of the side of the additional storage cavity 20a away from the main storage cavity 10a and the first liquid storage component 12 jointly limit the second liquid storage component 25 in the first direction, thereby reducing the probability that the second liquid storage component 25 moves and is no longer in fluid communication with the first liquid storage component 12 due to factors such as shaking of the aerosol generating device. On the other hand, with the consumption of the aerosol generating substrate in the additional storage cavity 20a, when a user uses the aerosol generating device, the second liquid storage component 25 can absorb the aerosol generating substrate remaining at the bottom of the additional storage cavity 20a, thereby improving the utilization of the aerosol generating substrate in the additional storage cavity 20a.
In some embodiments in which the fluid channel 20b extends in the first direction, referring to FIG. 14 and FIG. 15, the second liquid storage component 25 fills the fluid channel 20b.
That is, no gap exists between the second liquid storage component 25 and a wall of the fluid channel 20b perpendicular to the first direction.
In this way, all the aerosol generating substrate flowing out of the additional storage cavity 20a needs to pass through the second liquid storage component 25, which helps limit an amount and a supplementing speed of the aerosol generating substrate entering the main storage cavity 10a, and reduce the probability that an excessive amount of the aerosol generating substrate flows into the main storage cavity 10a excessively quickly and consequently the first liquid storage component 12 is supersaturated.
In some embodiments, referring to FIG. 16, in a projection plane perpendicular to the first direction, a projection of the second liquid storage component 25 is located within a projection range of the fluid channel 20b.
On the one hand, this helps mount the second liquid storage component 25 into the housing component 21 in the first direction during production and assembly of the additional e-liquid tank 20. On the other hand, this helps reduce the space of the additional storage cavity 20a occupied by the second liquid storage component 25, so that the additional storage cavity 20a can store more aerosol generating substrates and have a longer service life.
It can be understood that the atomizer 10 requires the atomization core 111 for converting the aerosol generating substrate into aerosols and is in direct contact with the mouth of a user, and hygiene requirements are higher. Therefore, the manufacturing costs of the atomizer 10 are higher than those of the additional e-liquid tank 20.
In some embodiments, referring to FIG. 10, FIG. 14, and FIG. 15, the additional e-liquid tank 20 is provided with an accommodating hole 21a, at least one side of the accommodating hole 21a in the first direction is open, and the atomizer 10 is at least partially located in the accommodating hole 21a.
It can be understood that the additional storage cavity 20a and the fluid channel 20b are both isolated from the accommodating hole 21a. A wall of the accommodating hole 21a can limit a part of the atomizer 10 that enters the accommodating hole 21a.
By using the accommodating hole 21a, the housing component 21 can protect at least a part of the atomizer 10, reducing the probability of damage to the atomizer 10 due to factors such as collision during usage of the aerosol generating device.
In some embodiments, referring to FIG. 4, the atomization component 11 includes the atomization core 111 and the mounting component 113, the mounting component 113 is provided with a mounting cavity and the air outlet channel 10b, the atomization core 111 is arranged in the mounting cavity, and the atomization core and a wall of the mounting cavity enclose to form the main storage cavity 10a, and the atomization core 111 is at least partially located in the accommodating hole 21a.
A part of the surface of the atomization core 111 forms a part of the wall of the main storage cavity 10a, so that the aerosol generating substrate in the main storage cavity 10a can be absorbed by the atomization core 111, and then the aerosol generating substrate is converted into aerosols by the atomization core 111.
The atomization core 111 is located in the accommodating hole 21a, and the housing component 21 can protect at least a part of the atomizer 10.
An open position on a side of the accommodating hole 21a forms a first accommodating opening 21b, and at least a part of the atomizer 10 can enter the accommodating hole 21a through the first accommodating opening 21b.
In some embodiments, referring to FIG. 3, the atomization core 111 is provided with an atomization cavity 111a, and the atomization cavity 111a is connected to the air outlet channel 10b. The atomization cavity 111a is isolated from the main storage cavity 10a, and aerosols generated by the atomization core 111 enter the atomization cavity 111a and are then discharged to the mouth of a user through the air outlet channel 10b.
In some embodiments in which a sealing cover 1131 and a mounting shell 1132 are provided, referring to FIG. 3, the mounting component 113 includes the sealing cover 1131 and the mounting shell 1132.
In some embodiments, referring to FIG. 4, the mounting shell 1132 is further provided with a second mounting groove 1132b and a connecting hole 1132c. A side of the second mounting groove 1132b that is the same as the side of the open position of the first mounting groove 1132a in the first direction is open, and the sealing cover 1131 seals an open position of the second mounting groove 1132b. The atomization core 111 is located inside the second mounting groove 1132b, and the atomization core and the wall of the second mounting groove 1132b enclose to form at least a part of the main storage cavity 10a. The connecting hole 1132c extends in the second direction and connects the first mounting groove 1132a to the second mounting groove 1132b. The connecting hole 1132c forms a part of the main channel 10c.
In this way, the sealing cover 1131 can achieve the sealing of both the main storage cavity 10a and the first sub-channel 10ca, which helps reduce a quantity of components and make the structure of the atomizer 10 more compact.
In some embodiments, referring to FIG. 4, FIG. 8, FIG. 9, and FIG. 10, one of the atomizer 10 and the additional e-liquid tank 20 can be in contact with a part of the other, and this part can move relative to another part of the other to connect the main storage cavity 10a to the additional storage cavity 20a or disconnect the main storage cavity from the additional storage cavity.
One of the atomizer 10 and the additional e-liquid tank 20 can be in contact with a part of the other, thereby forming a force transmission path between the atomizer 10 and the additional storage cavity.
After a user applies a force to at least one of the atomizer 10 or the additional e-liquid tank 20, one part of the atomizer 10 and the additional e-liquid tank 20 can synchronously move relative to another part of the atomizer 10, and one part of the additional e-liquid tank 20 and the atomizer 10 can synchronously move relative to another part of the additional e-liquid tank 20, so that a part of the other can move to at least two different relative positions relative to another part of the other. When the atomizer and the additional e-liquid tank are in a status of one relative position, the main storage cavity 10a is connected to the additional storage cavity 20a. When the atomizer and the additional e-liquid tank are in a status of another relative position, the main storage cavity 10a is disconnected from the additional storage cavity 20a, and the aerosol generating substrate can no longer flow from the additional storage cavity 20a into the main storage cavity 10a.
In this way, the additional e-liquid tank 20 and the atomizer 10 need to be in fit with each other to achieve relative movement of one part of one of the additional e-liquid tank and the atomizer to another part, to connect the main storage cavity 10a to the additional storage cavity 20a or disconnect the main storage cavity from the additional storage cavity. This helps reduce the probability that the aerosol generating substrate leaks because the main storage cavity 10a or the additional storage cavity 20a is accidentally opened during separate packaging and transportation of the additional e-liquid tank 20 or the atomizer 10.
In some implementations, referring to FIG. 4 and FIG. 10, the additional e-liquid tank 20 includes a movable sealing block 22 and the housing component 21. The housing component 21 includes the fluid channel 20b and the additional storage cavity 20a. The fluid channel 20b is connected to the outside of the housing component 21, and the movable sealing block 22 is provided with a penetrating transfer channel 22a. The atomizer 10 can push the movable sealing block 22 to move relative to the housing component 21, to switch the additional e-liquid tank 20 between a connected status and a sealed status. In the sealed status, the movable sealing block 22 closes the fluid channel 20b. In the connected status, the fluid channel 20b is opened so that the main storage cavity 10a is connected to the additional storage cavity 20a.
By forming a force transmission path between the atomizer 10 and the movable sealing block 22, the movable sealing block 22 can rotate with the atomizer 10 and therefore rotate relative to the housing component 21. Movement includes translation and rotation.
Translation refers to that the movable sealing block 22 can move in a straight line direction relative to the housing component 21.
Rotation refers to that the movable sealing block 22 can rotate around a straight line as the rotation center relative to the housing component 21.
In the sealed status, the movable sealing block 22 moves to a first position relative to the housing component 21, so that the movable sealing block 22 covers an opening of the fluid channel 20b that is configured to be connected to the outside of the housing component 21.In this way, it is difficult for the aerosol generating substrate to leak from the fluid channel 20b.
In the connected status, the movable sealing block 22 moves to a second position relative to the housing component 21, and a part of the atomizer 10 that is located in the transfer channel 22a can be connected to the fluid channel 20b, so that the aerosol generating substrate in the additional storage cavity 20a enters the atomizer 10 through the transfer channel 22a.
In some embodiments, referring to FIG. 4 and FIG. 10, the movable sealing block 22 is located outside the housing component 21. In some embodiments, a part of the atomizer 10 can be inserted into the transfer channel 22a through an end opening of the transfer channel 22a, so that the part of the atomizer 10 can abut against a wall of the transfer channel 22a to push the movable sealing block 22 to move.
It can be understood that in a status in which the additional e-liquid tank 20 is separated from the atomizer 10, the additional e-liquid tank 20 is in a sealed status.
It can be understood that the atomizer 10 cannot enter the fluid channel 20b, to avoid that the atomizer 10 abuts against the wall of the fluid channel 20b and consequently the movable sealing block 22 cannot move relative to the housing component. It can be understood that when a user operates the atomizer 10 to rotate relative to the housing component 21, the user needs to be able to perceive that the additional e-liquid tank 20 has been switched to the sealed status, to reduce the risk of leakage of the aerosol generating substrate caused by misoperation of the user.
Specifically, referring to FIG. 5 to FIG. 7 and FIG. 10, one of the additional e-liquid tank 20 and the atomizer 10 is provided with a slider 213, the other of the additional e-liquid tank and the atomizer is provided with a sliding groove 11d and a limiting groove 11e, the sliding groove 11d extends in a penetration direction of the transfer channel 22a, one end of the sliding groove 11d in the penetration direction of the transfer channel 22a is open to form an entrance/exit 11g, the other end of the sliding groove is connected to the limiting groove 11e, the limiting groove 11e extends in a rotation direction of the movable sealing block 22, a limiting surface 11f is provided on a side of the limiting groove in a rotation direction of the movable sealing block 22, the slider 213 can enter and exit the sliding groove 11d through the entrance/exit 11g and slide in the sliding groove 11d and the limiting groove 11e, and in the connected status, the slider 213 abuts against the limiting surface 11f in the rotation direction of the movable sealing block 22.
In a process of inserting a part of the atomizer 10 into the transfer channel 22a, the slider 213 synchronously enters the sliding groove 11d through the entrance/exit 11g, and moves in the penetration direction of the transfer channel 22a until the depth of insertion of the atomizer 10 into the transfer channel 22a meets a preset requirement. Then, the atomizer 10 and the movable sealing block 22 can rotate together, so that the slider 213 synchronously rotates relative to the wall of the limiting groove 11e, until the slider 213 abuts against a wall of a side of the limiting surface 11f in the rotation direction of the movable sealing block 22, so that the atomizer 10 and the movable sealing block 22 can no longer rotate relative to the housing component 21. In this way, a user can perceive, through a force feedback generated by the inability to rotate, that the movable sealing block 22 is in a connected status, and can use the aerosol generating device normally. In the connected status, the slider 213 can be in fit with the wall of the limiting groove 11e in the first direction to block, thereby reducing the probability of separation between the atomizer 10 and the additional e-liquid tank 20 in the first direction.
It can be understood that the rotation of the slider 213 relative to the wall of the limiting groove 11e has two directions. In some embodiments, at least one of the atomizer 10 and the additional e-liquid tank 20 is provided with an indication pattern of the rotation direction, so that the user can obtain a preset direction of the rotation direction of the slider 213 relative to the wall of the limiting groove 11e based on the indication pattern, thereby improving user experience.
Quantities of sliding grooves 11d and limiting grooves 11e are the same as a quantity of sliders 213, and the quantity of sliders 213 can be one or more.
In some embodiments, referring to FIG. 10, the sliding groove 11d and the limiting groove 11e or the slider 213 are provided on the wall of the accommodating hole 21a, to reduce the probability that a foreign object enters the sliding groove 11d and the limiting groove 11e and consequently the atomizer 10 and the movable sealing block 22 cannot rotate relative to each other.
In some embodiments, the slider 213 is provided with a fastening groove, and the limiting groove 11e is provided with a positioning protrusion. A limiting surface 11f is formed on a surface of a side of the positioning protrusion in the rotating direction of the movable sealing block 22. The slider 213 can produce elastic deformation to enable the positioning protrusion to be embedded in the fastening groove. In the connected status, the positioning protrusion is embedded in the fastening groove, and the limiting surface 11f abuts against the wall of the fastening groove in the rotating direction of the movable sealing block 22.
This helps the atomizer 10 and the housing component 21 maintain stable positions in the rotation direction of the movable sealing block 22.
In some embodiments, referring to FIG. 10, the additional e-liquid tank 20 further includes a block cover 23, the block cover 23 covers the outer surface of the housing component 21, and the block cover and the housing component 21 enclose to form a limiting space. The fluid channel 20b is connected to the limiting space, and the movable sealing block 22 is located in the limiting space. Two ends of the movable sealing block 22 in the penetration direction of the transfer channel 22a are respectively in fit with the block cover 23 and the housing component 21 to block, and the block cover 23 is provided with an avoidance channel 23a that penetrates in the penetration direction of the transfer channel 22a. The avoidance channel 23a connects the transfer channel 22a to the outside of the additional e-liquid tank 20. A part of the atomizer 10 can be inserted into the transfer channel 22a by penetrating through the avoidance channel 23a.
The movable sealing block 22 is located within the limited space and is sandwiched between the block cover 23 and the housing component 21, thereby limiting the range of movement of the movable sealing block 22 and reducing the probability that the movable sealing block 22 and the housing component 21 are detached.
After a part of the atomizer 10 is inserted into the transfer channel 22a, the atomizer can move within the avoidance channel 23a. A wall of the avoidance channel 23a can guide and constrain the movement of the atomizer 10, so that the movable sealing block 22 can move according to a predetermined movement path.
In some embodiments, referring to FIG. 1, FIG. 3, and FIG. 11, the aerosol generating device further includes a power component 30 that can be electrically connected to the atomizer 10. The power component 30 can supply electrical energy to the atomizer 10, so that the atomizer 10 can convert electrical energy into thermal energy to convert the aerosol generating substrate into aerosols.
In some embodiments, referring to FIG. 11, the power component 30 is provided with an accommodating groove 30a, and a side of the accommodating groove 30a in the first direction is open. An electrical connection region 10i for electrical connection to the power component 30 is provided on an end face of a side of the atomizer 10 that faces the power component 30. A wall of the accommodating groove 30a away from an open position of the accommodating groove is provided with a power supply region 30b. At least a part of the atomizer 10 can be inserted into the accommodating groove 30a, so that the electrical connection region 10i is electrically connected to the power supply region 30b, thereby enabling the power component 30 to supply power to the atomizer 10.
The wall of the accommodating groove 30a helps separate the electrical connection region 10i and the power supply region 30b from a part outside the aerosol generating device, thereby reducing the probability of poor contact between the electrical connection region 10i and the power supply region 30b caused by an external foreign object.
In some embodiments in which the accommodating groove 30a is provided, referring to FIG. 3, FIG. 5, and FIG. 11, a positioning protrusion 31 is provided on a wall of the accommodating groove 30a away from an open position of the accommodating groove. A rotation axis 22b of the movable sealing block 22 is in the first direction, and an end face of a side of at least one of the additional e-liquid tank 20 and the atomizer 10 in the first direction is a stop end face 10j. The stop end face 10j is provided with a positioning groove 10k that is open on a side of the first direction. The aerosol generating device includes an electrical conductive status and an electrical disconnected status. In the electrical conductive status, the positioning protrusion 31 is embedded in the positioning groove 10k and is in fit with a wall of the positioning groove 10k to prevent rotation. In the electrical disconnected status, the stop end face 10j abuts against the positioning protrusion 31 in the first direction.
It can be understood that parts of the additional e-liquid tank 20 and the atomizer 10 other than the stop end face 10j do not protrude from the stop end face 10j in the first direction.
After a user inserts the atomizer 10 into the accommodating groove 30a, if the positioning protrusion 31 is not aligned with the positioning groove 10k, because the stop end face 10j abuts against the positioning protrusion 31, the electrical connection region 10i cannot be in contact with the power supply region 30b, and the aerosol generating device is in the electrical disconnected status. Compared with the electrical conductive status, a part of the atomizer 10 is located outside the accommodating groove 30a. In addition, due to the small contact area between the positioning protrusion 31 and the stop end face 10j, the atomizer 10 is prone to shaking in a direction perpendicular to the first direction in the accommodating groove 30a, so that the user can perceive that the aerosol generating device is currently in the electrical disconnected status. The user rotates the atomizer 10 until the positioning protrusion 31 is aligned with the positioning groove 10k, so that the positioning protrusion 31 is embedded in the positioning groove 10k, the electrical connection region 10i is in contact with the power supply region 30b, and the aerosol generating device is in the electrical conductive status. In addition, the wall of the positioning groove 10k limits the positioning protrusion 31, so that at least one of the atomizer 10 and the additional e-liquid tank 20 cannot rotate relative to the power component 30, so that the user can perceive that the aerosol generating device is currently in the electrical conductive status.
In some embodiments, referring to FIG. 5, an end face of a side of the additional e-liquid tank 20 in the first direction is a second end face 20f, and an end face of a side of the atomizer 10 in the first direction is a first end face 10e. Both the first end face 10e and the second end face 20f form the stop end face 10j.
In some embodiments, a part of the stop end face 10j forms the electrical connection region 10i, and the power supply region 30b is formed in a part that is of the wall of the accommodating groove 30a away from the open position of the accommodating groove and that is outside the positioning protrusion 31.
In some embodiments, referring to FIG. 5 and FIG. 7, the positioning groove 10k includes a first positioning sub-groove 20i and a second positioning sub-groove 11h. The additional e-liquid tank 20 is provided with the stop end face 10j and is provided with the first positioning sub-groove 20i. The atomizer 10 is provided with the stop end face 10j and is provided with the second positioning sub-groove 11h. The first positioning sub-groove 20i and the second positioning sub-groove 11h are both open in a radial direction of a rotation axis 22b of the movable sealing block 22 and are open in opposite directions. In the sealed status, open positions of the first positioning sub-groove 20i and the second positioning sub-groove 11h in the radial direction of the rotation axis 22b of the movable sealing block 22 are opposite to each other. In the electrical conductive status, the positioning protrusion 31 is inserted into the first positioning sub-groove 20i and the second positioning sub-groove 11h.
In the electrical conductive status, a part of the positioning protrusion 31 is located in the first positioning sub-groove 20i and another part of the positioning protrusion is located in the second positioning sub-groove 11h. In this way, the positioning protrusion is in fit with both the wall of the first positioning sub-groove 20i and the wall of the second positioning sub-groove 11h to prevent rotation, so that a force transmission path is formed among the atomizer 10, the additional e-liquid tank 20, and the positioning protrusion 31. This suppresses the relative rotation trend between the atomizer 10 and the additional e-liquid tank 20 in the electrical conductive status, helps maintain the connected status of the additional e-liquid tank 20 in the electrical conductive status, and helps maintain the long-term stable operation of the aerosol generating device.
In some embodiments, the atomizer 10 is detachably connected to the additional e-liquid tank 20 to facilitate replacement of the additional e-liquid tank 20.
A specific manner of detachable connection between the atomizer 10 and the additional e-liquid tank 20 is not limited. For example, one of the atomizer 10 and the additional e-liquid tank 20 is provided with an elastic buckle, and the other is provided with a disassembly hole. Elastic deformation enables the elastic buckle to be inserted into or detached from the disassembly hole.
The various embodiments/implementations of the present invention can be combined with each other provided that no contradiction occurs.
The foregoing description is merely the preferred technical solutions of the embodiments of the present invention and is not intended to limit the protection scope of the embodiments of the present invention, and various changes and modifications may be made to the embodiments of the present invention by a person skilled in the art. Any modification, equivalent replacement, or improvement made without departing from the principle of the embodiments of the present invention shall fall within the protection scope of the embodiments of the present invention.
