Description

TECHNICAL FIELD

The present disclosure relates to the technical field of simulated smoking, in particular to an atomizer and an aerosol generating device having the same.

BACKGROUND

In the conventional atomizer, since the storage chamber and the atomizing chamber are connected, when the aerosol generating device is not used for a long time, the aerosol-forming substrate in the storage chamber may enter the atomizing chamber and be absorbed by the liquid absorbing member. Since the atomizing chamber is connected to the outside environment, the aerosol-forming substrate absorbed by the liquid absorbing member is easily volatilized to the outside, so that the liquid-absorbing member may repeatedly absorb the aerosol-forming substrate in the storage chamber. When the user uses the aerosol-generating device again, part of the aerosol-forming substrate in the storage chamber has been absorbed by the liquid absorbing member, and the amount of the aerosol-forming substrate in the storage chamber is reduced, so that the aerosol-forming substrate in the storage chamber is not easily stored. Further, since the atomizing chamber is also communicated with the air inlet hole, when the amount of the aerosol-forming substrate adsorbed by the liquid absorbing member is saturated, the aerosol-forming substrate in the storage chamber may leak to the outside through the air inlet hole. Further, since the aerosol-forming substrate is in contact with the air for a long time, the aerosol-forming substrate may become deteriorated, thus affecting the user's experience in use.

Please refer to FIG. 1 to FIG. 5, the atomizer 100 includes a liquid storage assembly 10 and an atomizing assembly 20 provided with an atomizing chamber 27. The liquid storage assembly 10 is used to store the aerosol-forming substrate, and the liquid storage assembly 10 is used to supply the aerosol-forming substrate to the atomizing assembly 20. The atomizing assembly 20 is electrically connected to the battery device, and the atomizing assembly 20 heats the aerosol-forming substrate in the liquid storage assembly 10 under the electric driving of the battery device. The smoke generated by heating the aerosol-forming substrate is mainly located in the atomizing chamber 27.
The term "the aerosol-forming substrate" is used to describe a substrate capable of releasing a volatile compound upon heating, which can form an aerosol. The aerosol-forming substrate can be solid or liquid, or comprise both solid and liquid components. In this embodiment, the aerosol-forming substrate is a liquid. The aerosol-forming substrate may include nicotine. The aerosol-forming substrate may also include other additives or ingredients, such as spices.
A liquid inlet channel 21 is provided in the atomizing assembly 20. The liquid storage assembly 10 includes a liquid storage member 11, and a storage chamber 111 for storing the aerosol-forming substrate is provided in the liquid storage member 11. The atomizing assembly 20 has a liquid sealing part 22, and the liquid sealing part 22 is provided with a liquid guiding hole 221 that communicates with the liquid inlet channel 21. The atomizing assembly 20 can move relative to the liquid storage assembly 10 from a liquid sealing position to a use position. When the atomizing assembly 20 is located in the liquid sealing position, the storage chamber 111 is sealed; when the atomizing assembly 20 is located in the use position, the liquid sealing part 22 at least partially extends into the storage chamber 111, and the aerosol-forming substrate in the storage chamber 111 can flow into the liquid inlet channel 21 through the liquid guiding hole 221.
Specifically, the liquid storage assembly 10 further includes a bracket 12 located in the liquid storage member 11. The bracket 12 partitions the inner cavity of the liquid storage member 11 into a storage chamber 111 for storing the aerosol-forming substrate and a mounting chamber 112 for installing the atomizing assembly 20. The atomizing assembly 20 is received in the mounting chamber 112. The atomizing assembly 20 has a liquid sealing part 22, and the liquid sealing part 22 is provided with a liquid guiding hole 221 that can communicate the storage chamber 111 with the liquid inlet channel 21. The atomizing assembly 20 is connected to the liquid storage member 11, and the atomizing assembly 20 can move axially between a liquid sealing position and a use position. When the atomizing assembly 20 is located in the liquid sealing position, the liquid guiding hole 221 is sealed by the bracket 12, and the aerosol-forming substrate in the storage chamber 111 cannot flow into the liquid inlet channel 21 through the liquid guiding hole 221. When the atomizing assembly 20 is located in the use position, the aerosol-forming substrate in the storage chamber 111 can flow into the liquid inlet channel 21 through the liquid guiding hole 221.
Specifically, the bracket 12 is provided with a liquid inlet hole 121 communicating with the storage chamber 111 and the mounting chamber 112. The liquid guiding hole 221 is formed at the side surface of the liquid sealing part 22. When the atomizing assembly 20 is located in the liquid sealing position, the side surface of the liquid sealing part 22 abuts against the inner wall of the liquid inlet hole 121 by interference fit, the liquid guiding hole 221 is sealed by the inner wall of the liquid inlet hole 121. When the atomizing assembly 20 moves axially upward to the use position, the liquid guiding hole 221 communicates the storage chamber 111 with the liquid inlet channel 21. During the process of moving the atomizing assembly 20 from the liquid sealing position to the use position, no liquid inlet gap will be generated between the liquid sealing part 22 and the bracket 12, so that the aerosol-forming substrate in the storage chamber 111 can only flow into the liquid inlet channel 21 through the liquid guiding hole 221.
Specifically, the bracket 12 and the liquid storage member 11 are two separate components, and the two can be detachably connected by means of snapping connection or plugging connection, etc. It can be understood that, in another embodiment not shown, the bracket 12 may also be integrally formed with the liquid storage member 11. When the atomizing assembly 20 is separated from the liquid storage assembly 10 and the bracket 12 is installed in place, the storage chamber 111 is located above the bracket 12, and the mounting chamber 112 is located below the bracket 12. At this time, the user can fill aerosol-forming substrate into the storage chamber 111 through the liquid inlet hole 121. Further, the liquid sealing part 22 is substantially in the form of a hollow cylindrical structure, when the atomizing assembly 20 is installed in the mounting chamber 112, the inner cavity of the liquid sealing part 22 communicates the liquid guiding hole 221 with the liquid inlet channel 21. When the atomizing assembly 20 is moved from the liquid sealing position to the use position, the liquid sealing part 22 extends into the storage chamber 111, and the aerosol-forming substrate in the storage chamber 111 flows into the liquid inlet channel 21 through the liquid guiding hole 221 and the inner cavity of the liquid sealing part 22 in sequence. It can be understood that the shape of the liquid sealing part 22 is not limited, the liquid sealing part 22 may also be tapered or rectangular. In addition, in order to prevent the aerosol-forming substrate in the storage chamber 111 from flowing into the mounting chamber 112 through the gap between the bracket 12 and the liquid storage member 11, a sealing member 13 is provided on the bracket 12. The sealing member 13 is made of a material with good sealing performance, such as silicone or rubber. When the bracket 12 is installed in place, the sealing member 13 is sandwiched between the outer surface of the bracket 12 and the inner surface of the liquid storage member 11 so as to seal the gap between the outer surface of the bracket 12 and the inner surface of the liquid storage member 11.
Specifically, the material of the bracket 12 is not limited, for example, in one of the embodiments, the liquid storage assembly 10 is at least partially made of an elastic material, the bracket 12 is made of a material with good elasticity such as silicone or rubber. The liquid guiding hole 221 is formed at the upper end surface of the liquid sealing part 22. When the atomizing assembly 20 is located in the liquid sealing position, the bracket 12 seals the aerosol-forming substrate in the storage chamber 111. During the process of moving the atomizing assembly 20 from the liquid sealing position to the use position, the liquid sealing part 22 squeezes the bracket 12 and pierces through the bracket 12, so that both ends of the bracket 12 are open. After the bracket 12 is pierced through, the inner cavity of the liquid sealing part 22 is communicated with the storage chamber 111, such that the aerosol-forming substrate in the storage chamber 111 can flow into the liquid inlet channel 21 through the liquid guiding hole 221. When the atomizing assembly 20 moves from the use position to the liquid sealing position and the liquid sealing part 22 releases the squeeze on the bracket 12, the bracket 12 is reset under its elastic force to cut off the communication between the storage chamber 111 and the liquid inlet channel 21. Specifically, one end of the liquid sealing part 22 close to the storage chamber 111 may be sharp in order to pierce through the bracket 12. It can be understood that, in another embodiment not shown, during the process of moving the atomizing assembly 20 from the liquid sealing position to the use position, the opening of the bracket 12 by the liquid sealing part 22 may also be destructive (i.e., unrecoverable), that is, the bracket 12 cannot cut off the communication between the storage chamber 111 and the liquid inlet channel 21 again, and thus the storage chamber 111 cannot be restored to the sealed state again.
Specifically, the liquid inlet channel 21 is located above the atomizing chamber 27. When the atomizing assembly 20 is in the use position, the aerosol-forming substrate in the storage chamber 111 flows into the atomizing chamber 27 via the liquid inlet channel 21. In this embodiment, a curved surface 211 is formed on the inner wall of the liquid inlet channel 21, and the curved surface 211 faces toward the atomizing chamber 27. When the atomizing assembly 20 is in the use position and the aerosol-forming substrate in the storage chamber 111 flows to the curved surface 211 through the liquid guiding hole 221, the curved surface 211 serves to guide the aerosol-forming substrate into the atomizing chamber 27.
Specifically, the lower end of the liquid storage member 11 is an open end. When the atomizing assembly 20 and the liquid storage member 11 are installed in place, the atomizing assembly 20 can seal the open end. The manner in which the atomizing assembly 20 is connected to the liquid storage member 11 includes but is not limited to snapping connection or screwing connection, etc., as long as the atomizing assembly 20 can move axially relative to the liquid storage member 11 between the liquid sealing position and the use position.
For example, in this embodiment, the atomizing assembly 20 includes an atomizing member 23, and the atomizing member 23 has a liquid sealing part 22. One of the atomizing member 23 and the liquid storage member 11 is provided with a latching protrusion 113, and the other one of the liquid storage member 11 and the atomizing member 23 is provided with a first groove 114 and a second groove 115. By engaging the latching protrusion 113 in the first groove 114 or the second groove 115, the atomizing member 23 and the liquid storage member 11 are fixedly connected with each other. Specifically, the first groove 114 and the second groove 115 are located on the same side. When the latching protrusion 113 is engaged in the first groove 114, the atomizer assembly 20 is in the liquid sealing position. When the latching protrusion 113 is engaged in the second groove 115, the atomizer assembly 20 is in the use position.
Specifically, the first groove 114 and the second groove 115 are provided on the inner surface of the liquid storage member 11, and the first groove 114 and the second groove 115 are arranged sequentially from bottom to top along the axial direction of the liquid storage member 11. The latching protrusion 113 is protruded on the outer surface of the atomizing member 23. In addition, the latching protrusion 113 may be made of a material with good elasticity such as silicone or rubber. When the latching protrusion 113 on the atomizing member 23 is switched from the first groove 114 to the second groove 115, the latching protrusion 113 is elastically compressed after being squeezed by the inner wall of the mounting chamber 112. When the latching protrusion 113 moves to a position corresponding to the second groove 115, the latching protrusion 113 returns to its original state under its elastic restoring force, so that the latching protrusion 113 is engaged in the second groove 115.
Further, the atomizing member 23 includes an atomizing base 231 and an atomizing casing 232 connected with the atomizing base 231. The latching protrusion 113 is protruded on the outer surface of the atomizing base 231. The atomizing base 231 and the atomizing casing 232 are two separate components, and the two can be detachably connected by snapping or plugging connection. It can be understood that, in another embodiment not shown, the atomizing base 231 may also be integrally formed with the atomizing casing 232, as long as the atomizing base 231 and the atomizing casing 232 are fixed to each other. In addition, in another embodiment not shown, the latching protrusion 113 may also be protruded on the outer surface of the atomizing casing 232.
Further, the atomizing casing 232 includes an atomizing main body 2321 and the liquid sealing part 22 protruding from the atomizing main body 2321. The liquid inlet channel 21 is provided in the atomizing main body 2321. The liquid sealing part 22 and the atomizing main body 2321 are integrally formed.
For example, in another embodiment not shown, the outer surface of the atomizing member 23 is provided with an external thread, the inner surface of the liquid storage member 11 is provided with an inner thread for cooperating with the outer thread. Rotating one of the atomizing member 23 and the liquid storage member 11 can make the atomizing assembly 20 move axially upward or downward relative to the liquid storage member 11, so that the atomizing assembly 20 is switched from the liquid sealing position to the use position, or the atomizing assembly 20 is switched from the use position to the liquid sealing position.
Please refer to FIG. 1, FIG. 3 and FIG. 5, in this embodiment, a sealing sleeve 24 is installed on the atomizing member 23. When the atomizing member 23 is installed in place, the sealing sleeve 24 is sandwiched between the inner surface of the liquid storage member 11 and the outer surface of the atomizing member 23. Through the tension fit between the sealing sleeve 24 and the inner wall of the mounting chamber 112, the gap between the liquid storage member 11 and the atomizing member 23 can be sealed. When the liquid guiding hole 221 communicates the storage chamber 111 with the liquid inlet channel 21, the aerosol-forming substrate can be prevented from leaking to the outside through the gap between the liquid storage member 11 and the atomizing member 23. Specifically, the sealing sleeve 24 is made of a material with good sealing performance, such as silicone or rubber.
In this embodiment, the atomizing assembly 20 further includes a heating structure 25 disposed in the liquid inlet channel 21. The heating structure 25 includes a liquid absorbing member and a heating member. The liquid absorbing member can absorb the aerosol-forming substrate in the storage chamber 111 and conduct the aerosol-forming substrate to the heating member. The heating member heats the aerosol-forming substrate under the electric driving of the battery device.
Specifically, the liquid absorbing member can be made of a material that is easy to absorb liquid, such as cotton or porous ceramics. In this embodiment, the liquid absorbing member is made of porous ceramic material.
Specifically, the heating member and the liquid absorbing member are arranged in contact with each other. The heating member may be arranged at the outside of the liquid absorbing member and/or at the inside of the liquid absorbing member. The heating member can be made of any one of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy and other materials. In this embodiment, the heating member is arranged on the lower end surface of the liquid absorbing member, and the surface of the heating member is an atomizing surface.
In this embodiment, the atomizing assembly 20 further includes a liquid sealing member 26 mounted on the heating structure 25. The liquid sealing member 26 is used for sealing the gap between the atomizing member 23 and the heating structure 25, so as to prevent the aerosol-forming substrate from leaking to the outside through the gap.
Specifically, the liquid sealing member 26 is made of an elastic material with good sealing performance, such as silicone or rubber. The liquid sealing member 26 made of an elastic material can prevent the heating structure 25 from being damaged, thereby increasing the service life of the heating structure 25. In this embodiment, the liquid sealing member 26 is made of silicone material, the liquid sealing member 26 made of silicone material has good high temperature resistance and thermal stability.
In this embodiment, the atomizing chamber 27 is a space jointly enclosed by the inner surface of the liquid sealing member 26, the inner surface of the atomizing base 231 and the lower end surface of the liquid absorbing member. The atomizing member 23 is provided with an air inlet hole 233 that communicates with the outside environment and the liquid inlet channel 21. The liquid storage member 11 is provided with a smoke outlet hole 116 that communicates with the outside environment. The liquid storage assembly 10 further includes a venting member 14 arranged in the liquid storage member 11. The inner cavity of the venting member 14 communicates the liquid inlet channel 21 with the smoke outlet hole 116. Under the suction effect, the outside air flows into the atomizing chamber 27 through the air inlet hole 233 and is mixed with the atomized smoke to form mixed gas, and then the mixed gas flows out from the smoke outlet hole 116 through the inner cavity of the venting member 14 for the user to inhale.
Specifically, the air inlet hole 233 is formed in the atomizing base 231. It can be understood that the number of the air inlet hole 233 is not limited and can be set according to the air intake demand of the atomizer 100.
Specifically, the venting member 14 is formed by protruding downward along the axial direction of the liquid storage member 11 around the smoke outlet hole 116. The venting member 14 and the liquid storage member 11 are integrally formed. The end of the venting member 14 away from the smoke outlet hole 116 is connected to the atomizing casing 232 through the sealing member 13 and the bracket 12.

Specifically, the sealing member 13 is provided with a first through hole, the atomizing main body 2321 is provided with a second through hole, the bracket 12 is provided with a third through hole connecting the first through hole and the second through hole, and the end of the venting member 14 away from the smoke outlet hole 116 passes through the first through hole and the third through hole in sequence and then is inserted into the second through hole.
In this embodiment, the atomizing base 231 is provided with two electrode contacts 234, and the two electrode contacts 234 are respectively electrically connected with the two pins of the heating member. When the atomizer 100 and the battery device are electrically connected, the battery device supplies power to the heating member through the electrode contacts 234.
In this embodiment, in order to improve the stability of the electrical connection between the atomizer 100 and the battery device, the atomizing base 231 is provided with a first attracting member 235. The battery device is provided with a second attracting member. Both the first attracting member 235 and the second attracting member are made of magnetic material. The magnetic poles of the first attracting member 235 and the second attracting member are different. When the atomizer 100 and the battery device are electrically connected, the first attracting member 235 and the second attracting member are magnetically attracted to enhance the stability of the electrical connection between the atomizer 100 and the battery device.
In addition, in order to prevent the atomizing member 23 and the liquid storage member 11 from being in rigid contact and improve the sealing performance and the service life, a gasket 236 is sleeved on the atomizing base 231. The gasket 236 is made of an elastic material such as silicone or rubber. When the atomizing member 23 moves axially upward to the use position, the gasket 236 is located between the atomizing base 231 and the liquid storage member 11 to seal the gap therebetween.
The battery device is detachably connected to the atomizer 100, and the detachable connection methods include but are not limited to snapping connection or plugging connection, etc. When the battery device and the atomizer 100 are installed in place, the positive and negative electrodes of the battery device are electrically connected to the two electrode contacts 234, respectively. The atomizer 100 can heat the aerosol-forming substrate and atomize the aerosol-forming substrate into smoke under the electric driving action of the battery device.
