Description

Technical field

[0001] The present application relates to the field of atomization technology, and in particular to an electronic atomization device. [Background Technology]

[0002] Traditional tobacco products (e.g., cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke during use. Products that release compounds by heating without burning are already available in the prior art as an alternative to these traditional tobacco products. Examples of such products are electronic atomization devices, which typically include an atomizer for storing and atomizing a liquid matrix to produce an aerosol, and a battery for providing electrical energy to the atomizer. The liquid matrix may contain nicotine and / or flavoring agents and / or an aerosol-forming substance (e.g., glycerin).

[0003] As an exemplary prior art, the above-mentioned electronic atomization device generally includes a plurality of atomizers that can be selected by the user, and each atomizer has a liquid storage chamber. The user can select one of the multiple atomizers through a switching operation to electrically connect the atomizer to the battery core, thereby increasing the amount of liquid matrix stored in the electronic atomization device, thereby increasing the number of suction ports of the electronic atomization device.

[0004] During the switching operation, the existing multiple atomizers can only be electrically connected to the output terminals of the battery cells one by one, and the user can only inhale a single flavor of aerosol each time. [Utility Model Content]

[0054] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0055] In the embodiments of the present application, the "installation" includes fixing or restricting a component or device to a specific position or place by welding, screwing, clamping, bonding, etc. The component or device can remain stationary at a specific position or place or can move within a limited range.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0057] An embodiment of the present application provides an electronic atomization device 100 for atomizing a liquid matrix to generate an aerosol, such as Figure 1 and Figure 2 As shown, the housing of the electronic atomization device 100 includes a mouthpiece 10, a main shell 20, and a bottom cover 30. The main shell 20 is located between the mouthpiece 10 and the bottom cover 30. The mouthpiece 10 is provided with an air outlet 11 for aerosol to escape from the electronic atomization device 100. The bottom cover 30 is provided with an air inlet 31 for external air to enter the electronic atomization device 100. An atomizer for atomizing a liquid matrix and generating an aerosol is provided within the main shell 20. When a user inhales at the air outlet 11, external air enters the electronic atomization device 100 through the air inlet 31 and carries the aerosol generated by the atomization through the internal airflow channel of the electronic atomization device 100 to the air outlet 11 for the user to inhale.

[0058] like Figure 3 As shown, a bracket 21 is provided in the main shell 20, and the bracket 21 can rotate relative to the nozzle 10 and the bottom cover 30. The bracket 40 includes a plurality of partitions 211 that are spaced apart and extend longitudinally. The plurality of partitions 211 are arranged circumferentially around the axis of the bracket 21, and a chamber 2111 is formed between any two adjacent plate-like bodies 211. An atomizer 22 is fixedly provided in each chamber 2111, so that the plurality of atomizers 22 are arranged around the axis of the bracket 21. The bracket 21 and the plurality of atomizers 22 are combined to form an atomization component of the electronic atomization device 100, and the atomization component is used to atomize the liquid matrix to generate an aerosol.

[0059] like Figure 4 As shown, the nebulizer 22 includes a housing 221, which defines a liquid storage chamber 2211 for storing atomized liquid matrix, and an air guide tube 2212 extending longitudinally within the liquid storage chamber 2211. The nebulizer 22 also includes a hollow tubular body 222, one end of which is inserted into the tubular body 222, and the other end of which is connected to the air outlet 11. An atomizing element 223 is disposed within the tubular body 222. The atomizing element 223 is configured to receive the liquid matrix in the liquid storage chamber 2211, atomize the liquid matrix to form an aerosol, and release it into the tubular body 222. The aerosol formed after atomization can then be transmitted along the air guide tube 2212 to the air outlet 11.

[0060] The nebulizer 22 also includes a first liquid-conducting element 224. The first liquid-conducting element 223 is used to absorb the liquid matrix in the liquid storage chamber 2211. The nebulizer 223 includes a second liquid-conducting element 2231 and a heating element 2232 combined with the second liquid-conducting element 2231. A through hole (not shown) is opened on the tube wall of the tubular body 222. A part of the second liquid-conducting element 2231 passes through the through hole and contacts the first liquid-conducting element 224. The first liquid-conducting element 224 can transfer the absorbed liquid matrix to the second liquid-conducting element 2231, and the heating element 2232 can heat and atomize the liquid matrix to form an aerosol.

[0061] Both the first liquid-conducting element 224 and the second liquid-conducting element 2231 are made of porous materials. For example, the first liquid-conducting element 224 and the second liquid-conducting element 2231 can be made of any of cotton fibers, non-woven fabrics, fiberglass ropes, porous ceramics, or porous glass. Thus, the first liquid-conducting element 224 and the second liquid-conducting element 2231 can absorb and transfer liquid matrices through their internal micropores or microporous structures. Accordingly, the heating element 2232 can be attached to the second liquid-conducting element 2231 by printing, deposition, sintering, or physical assembly, or can be wound around the second liquid-conducting element 2231.

[0062] The nebulizer 22 also includes an air inlet 226 and an air outlet 227 arranged opposite to each other along its length. The air inlet 226 is used to allow external air to enter the nebulizer 22, and the air outlet 227 is used to allow the aerosol formed after atomization by the nebulizer 22 to escape from the nebulizer 22. Therefore, when the user inhales at the air outlet 11, external air can enter the nebulizer 22 through the air inlet 226 and carry the aerosol generated after atomization to escape from the nebulizer 22 from the air outlet 227.

[0063] like Figure 5-10 As shown, the atomizer 22 also includes a conductive electrode 225 electrically connected to the heating element 2232. The bottom cover 30 is provided with a power supply assembly of the electronic atomization device 100, which is used to provide the electrical energy required for heating the heating element 2232. The power supply assembly includes a circuit board 32 and a battery cell (not shown), and a plurality of electrical connection terminals 321 provided on the circuit board 32. The bracket 21 drives the atomization assembly to rotate relative to the power supply assembly, so that the electrical connection terminal 321 can selectively be electrically connected to at least one of the atomizers 22, thereby allowing the battery cell to provide electrical energy to the atomizer 22.

[0064] Furthermore, the bracket 21 is rotatable relative to the power supply assembly between a first position and a second position. When the bracket 21 is rotated to the first position, the conductive electrode 225 of only one atomizer 22 is matched with the corresponding electrical connection terminal 321 for electrical connection, thereby establishing a power supply circuit with the battery cell, so that the battery cell only provides electrical energy to the atomizer 22. At the same time, the air duct 2212 of the atomizer 22 is rotated to communicate with the air outlet 11. When the bracket 21 is rotated to the second position, the conductive electrodes 225 of at least two atomizers 22 are electrically connected to the corresponding electrical connection terminals 321, thereby establishing a power supply circuit with the battery cell, thereby enabling the battery cell to provide electrical energy to the at least two atomizers 22 through the electrical connection terminals 321. At this time, the air duct 2212 in each atomizer 22 is rotated to communicate with the air outlet 11.

[0065] The raw materials and proportions of the liquid matrix stored in each atomizer 22 can be different, resulting in a different flavor of the aerosol formed after atomization in each atomizer 22. When the bracket 21 is rotated to the first position, the battery cell supplies power to only one atomizer 22, and an aerosol of a single flavor is produced at the air outlet 11. When the bracket 21 is rotated to the second position, the battery cell supplies power to at least two atomizers 22. Each atomizer 22 receives power to atomize the liquid matrix stored therein, thereby producing an aerosol of the corresponding flavor. As a result, a mixed aerosol formed by mixing at least two aerosols can be produced at the air outlet 11.

[0066] In the above manner, the user only needs to operate the bracket 21 to rotate between the first position and the second position to establish a power supply circuit between one or at least two atomizers and the battery cell, thereby enabling one or at least two atomizers to work, and then enabling the electronic atomization device 100 to produce a single-flavor aerosol or a mixed-flavor aerosol obtained by mixing at least two aerosols.

[0067] In some embodiments, as Figure 11 As shown, the electronic atomization device 100 further includes a rotating shaft 213, and the atomization component rotates relative to the power supply component around the rotating shaft 213. The multiple electrical connection terminals 321 on the power supply component are sequentially spaced on an arc with the rotating shaft 213 as the center, so that the electrical connection terminals 321 respectively correspond to the conductive electrodes 225 of the atomization component on the arc with the rotating shaft 213 as the circle, and then when the atomization component rotates, the conductive electrodes 225 of one or more atomizers can be electrically connected to the electrical connection terminals 321, thereby establishing a power supply circuit with the battery cell. Further in some embodiments, as Figure 5 and Figure 6As shown, the power supply assembly includes four electrical connection terminals 321, which are arranged sequentially along an arc centered on the rotation axis 213 at predetermined arc angles. The angle between the first and second positions of the bracket 21 is the same as the arc angle between any two adjacent electrical connection terminals 321. As the bracket 21 rotates, one of the atomizers 22 will be electrically connected to the two intermediate electrical connection terminals 321, thereby establishing a power supply circuit with the battery cells. At this point, the battery cells can supply power to the atomizer 22, enabling it to operate, and the bracket 21 rotates to the first position. When the bracket 21 continues to rotate from the first position at the aforementioned angle, two of the atomizers 22 will be electrically connected to the four electrical connection terminals 321. At this point, the battery cells can supply power to the two atomizers 22, enabling them to operate, and the bracket 21 rotates to the second position. This embodiment enables the electronic atomization device 100 to switch between a single-flavor aerosol mode and a dual-flavor mixed aerosol mode.

[0068] Specifically, such as Figure 7 and Figure 9 As shown, the four electrical connection terminals 321 are respectively a first electrical connection terminal 321a, a second electrical connection terminal 321b, a third electrical connection terminal 321c and a fourth electrical connection terminal 321d. The bracket 21 is provided with a first atomizer 22a, a second atomizer 22b and a third atomizer 22c. The second atomizer 22b is located between the first atomizer 22a and the third atomizer 22c. When the bracket 21 is rotated to the first position, the two conductive electrodes of the second atomizer 22b are respectively in contact with the second electrical connection terminal 321b and the third electrical connection terminal 321c, one of the conductive electrodes of the first atomizer 22a is in contact with the first electrical connection terminal 321a, and one of the conductive electrodes of the third atomizer 22c is in contact with the fourth electrical connection terminal 321d.

[0069] Because the conductive electrodes of the first and third atomizers 22a, 22c each abut only one electrical connection terminal, they cannot form a current loop, and therefore cannot function properly. However, the conductive electrodes of the second atomizer 22b abut the two middle electrical connection terminals 321, allowing the second atomizer 22b to form a current loop. The battery cell can supply electrical energy to the second atomizer 22b via the second and third electrical connection terminals 321b, 321c, enabling the second atomizer 22b to function properly. Simultaneously, the air guide tube 2212b in the second atomizer 22b rotates to a position communicating with the air outlet 11. The aerosol generated at the air outlet 11 is derived solely from the single aerosol formed by the atomization of the liquid matrix in the second atomizer 22b.

[0070] When the bracket 21 rotates clockwise to the second position, the two conductive electrodes of the first atomizer 22a are respectively in contact with the first electrical connection terminal 321a and the second electrical connection terminal 321b, and the two conductive electrodes of the second atomizer 22b are respectively electrically connected to the third electrical connection terminal 321c and the fourth electrical connection terminal 321d. At this time, the battery cell can provide electrical energy to the first atomizer 22a and the second atomizer 22b, and the first atomizer 22a and the second atomizer 22b can operate normally. At the same time, the air guide tube 2212a of the first atomizer 22a and the air guide tube 2212b of the second atomizer 22b are rotated to a position connected to the air outlet 11. The aerosol generated at the air outlet 11 comes from the mixed aerosol formed after the liquid matrix in the first atomizer 22a and the second atomizer 22b is atomized, such as Figure 8 and Figure 10 shown.

[0071] Alternatively, in some embodiments, the bracket 21 can also be rotated counterclockwise from the first position to the second position. At this time, the two conductive electrodes 225b of the second atomizer 22b are electrically connected to the first electrical connection terminal 321a and the second electrical connection terminal 321b, respectively, and the two conductive electrodes 225c of the third atomizer 22c are electrically connected to the third electrical connection terminal 321c and the fourth electrical connection terminal 321d, respectively. At this time, the battery cell can provide electrical energy to the second atomizer 22b and the third atomizer 22c, and the second atomizer 22b and the third atomizer 22c can operate normally. At the same time, the air guide tube 2212b of the second atomizer 22b and the air guide tube 2212c of the third atomizer 22c are rotated to a position connected to the air outlet 11. The aerosol generated at the air outlet 11 comes from the mixed aerosol formed after the liquid matrix in the second atomizer 22b and the third atomizer 22c is atomized.

[0072] Furthermore, as can be seen from the switching method described in the above embodiment, the number of atomizers 22 is related to the rotation angle between the first position and the second position. For example, when the number of atomizers 22 is four, the rotation angle between the first position and the second position is 45 degrees; when the number of atomizers 22 is five, the rotation angle between the first position and the second position is 36 degrees; and when the number of atomizers 22 is six, the rotation angle between the first position and the second position is 30 degrees. To facilitate the user's operation of rotating the bracket 21, the number of atomizers 22 is preferably four, and the corresponding rotation angle between the first position and the second position is 45 degrees.

[0073] In some embodiments, as Figure 5As shown, the bracket 21 has multiple first positions S1 and multiple second positions S2 relative to the power supply assembly. A second position S2 is located between any two adjacent first positions S1, or in other words, a first position S1 is located between any two adjacent second positions S2. In other words, the first positions S1 and second positions S2 are alternately distributed around the circumference, allowing the bracket 21 to switch between multiple first positions S1 and multiple second positions S2 along the rotational direction. Furthermore, in different first positions S1, the aerosol generating device 100 will produce single aerosols of different flavors; similarly, in different second positions S2, the aerosol generating device 100 will produce mixed aerosols of different flavors.

[0074] In some embodiments, as Figure 5 and Figure 6 As shown, the power supply assembly further includes a support member 34 for providing support for the bracket 21. The battery cell is mounted on the support member 34, so that the bracket 21 can rotate relative to the support member 34. The support member 34 is provided with a protrusion 341 extending toward the bracket 21, and the bracket 21 is provided with a groove 212 adapted to the protrusion 21. When the bracket 21 is rotated to the first position or the second position, the protrusion 341 falls into the groove 212, thereby providing a feedback to the user, informing the user that the bracket 21 has been rotated to the first position or the second position.

[0075] It is easy to understand that when there are multiple first positions or second positions, the number of corresponding grooves 212 is also multiple. Figure 5 As shown, the bracket 21 has four first positions S1 and four second positions S2 , so the number of the grooves 212 is eight, so that when the bracket 21 rotates to any first position S1 or second position S2 , feedback can be provided to the user.

[0076] Alternatively, in some embodiments, the protrusion 341 may also be provided on the bracket 21 , and the groove 212 may be provided on the support member 34 accordingly.

[0077] And, in some embodiments, as Figure 11 As shown, the protrusions 341 include two, and the two protrusions 341 are symmetrically arranged about the rotation axis 213 of the bracket 21. When the bracket 21 rotates to one of the first positions S1 or the second positions S2, the two protrusions 341 can correspondingly fall into the two grooves 212 symmetrically arranged about the rotation axis 213, thereby improving the feel applied to the user when the bracket 2 rotates to the first position or the second position.

[0078] In some embodiments, as Figure 1As shown, the air outlet 11 of the nozzle 10 is set away from the central axis L of the electronic atomization device 100, that is, the air outlet 11 is not set in the central area of ​​the nozzle 10. The eccentric setting of the air outlet 11 allows the aerosol generated by the atomization component to easily escape from the air outlet 11 regardless of whether the bracket 21 is rotated to the first position or the second position.

[0079] In some embodiments, the electronic atomization device 100 includes a first air inlet channel and multiple second air inlet channels that are independent of each other. The air inlet channel is used to guide external air into the atomizer 22. When the bracket 21 rotates to the first position, the battery cell provides electrical energy to one of the atomizers 22, so that the atomizer 22 can work normally. At this time, the first air inlet channel is connected to the air inlet 226 of the atomizer 22, thereby guiding external air into the atomizer 22.

[0080] When the bracket 21 rotates to the second position, the battery cell provides power to the multiple atomizers 22, so that the multiple atomizers 22 can work normally. At this time, the multiple second air inlet channels are connected to the air inlets 226 of the multiple atomizers 22, thereby guiding the external air into the multiple atomizers 22 respectively.

[0081] By providing a mutually independent first air inlet channel and a plurality of second air inlet channels, when the bracket 21 is rotated to the first position or the second position, an independent air inlet channel is provided to guide the external air into the atomizer 22 accordingly, thereby improving the inhalation taste of the aerosol.

[0082] In a specific embodiment, Figure 11 and Figure 12 As shown, the support member 34 is formed with a longitudinally extending first tubular body 342a and multiple second tubular bodies 342b. Both the first tubular body 342a and the second tubular body 342b are hollow to transmit airflow. The first tubular body 342a is hollow to define a first air inlet channel, and the second tubular body 342b is hollow to define a second air inlet channel. The first tubular body 342a has a first airflow outlet 3421a, and the second tubular body 342b has a second airflow outlet 3421b. Furthermore, the first airflow outlet 3421a is located between the electrical connection terminal 321b and the electrical connection terminal 321c, and the two second airflow outlets 3421b are located between the electrical connection terminal 321a and the electrical connection terminal 321b, and between the electrical connection terminal 321c and the electrical connection terminal 321d, respectively. In other words, an air inlet channel is provided between any two adjacent electrical connection terminals 321.

[0083] Thus, when the bracket 21 rotates to the first position, Figure 12As shown, the first airflow outlet 3421a of the first tubular body 342a is aligned with the air inlet 226b of the second atomizer 22b, while the second airflow outlet 3421b is staggered with the air inlet 226a of the first atomizer 22a and the air inlet 226c of the third atomizer 22c, respectively. At this time, external air can enter the second atomizer 22b through the first tubular body 342a, while no air enters the first atomizer 22a and the third atomizer 22c. Furthermore, when the bracket 21 is rotated to the first position, as described in the above embodiment, only the second atomizer 22a can function normally, while the first atomizer 22a and the third atomizer 22c cannot function normally.

[0084] When the bracket 21 rotates clockwise to the second position, Figure 13 As shown, the second air flow outlet 3421b is aligned with the air inlet 226a of the first atomizer 22a and the air inlet 226b of the second atomizer 22b, respectively, so that external air can enter the first atomizer 22a and the second atomizer 22b respectively through the second tubular body 342b, while the first air flow outlet 3421a is staggered with the air inlet 226a of the first atomizer 22a and the air inlet 226b of the second atomizer 22b respectively. And when the bracket 21 is rotated to the second position, it can be seen from the description of the above embodiment that the first atomizer 22a and the second atomizer 22b can operate normally at this time. In some embodiments, as Figure 14 and Figure 15 As shown, a first sealing member 35 is further provided in the bottom cover 30. The first sealing member 35 can be any one of silicone, rubber or latex. The first sealing member 35 has a first surface 351 and a second surface 352 that are oppositely arranged. A first groove 3511 is formed on the first sealing member 351. An airflow sensor (not shown) is interference fitted in the first groove 3511, so that the first sealing member 35 can hold and seal the airflow sensor.

[0085] The first seal 35 also includes a plurality of air vents 353 connecting the first surface 351 and the second surface 352. The first air inlet channel and the second air inlet channel are respectively connected to the air vents 353. The bottom opening of the first groove 3511 is set so that the airflow sensor is at least partially exposed to the second surface 352. The seal 35 also forms an airflow channel connecting the air vents 353 and the airflow sensor. The airflow channel is used to trigger the airflow sensor during inhalation, so that the airflow sensor generates a sensing signal, and then the electronic atomization device 100 can start working according to the sensing signal.

[0086] In some embodiments, as Figure 14As shown, the airflow channel can be defined and formed by a plurality of second grooves 3521 on the second surface 352, and the second grooves 3521 are connected to the first air inlet channel and the second air inlet channel through the vents 353 respectively. That is to say, part of the airflow in the first air inlet channel and the second air inlet channel can be converged to the airflow sensor through the plurality of second grooves 3521, so that the airflow sensor can be triggered when the electronic atomization device 100 is in the single aerosol mode and the mixed aerosol mode, and thus the airflow sensor can be shared in the single aerosol mode and the mixed aerosol mode.

[0087] Alternatively, a through hole may be provided between the vent hole 353 and the first groove 3511 to form an air flow channel.

[0088] The number of air flow sensors can be as follows Figure 16 The one shown in , or it can be Figure 14 The two shown in .

[0089] In some embodiments, as Figure 17 As shown, the mouthpiece 10 is also provided with a second sealing member 12, which is located between the air outlet 11 and the plurality of atomizers 22. The second sealing member 12 can be any one of silicone, rubber, or latex. The second sealing member 12 is used to seal the air outlet 227 of the atomizer 22. The second sealing member 12 is also formed with a first air guide hole 121 and a plurality of second air guide holes 122 for guiding the aerosol escaping from the air outlet 227 to the air outlet 11. When the bracket 21 is rotated to the first position, the air guide tube 2212b of the atomizer 22b is connected to the air outlet 11 through the first air guide hole 121, and the second air guide hole 122 is blocked. Figure 9 When the bracket 21 rotates to the second position, the air guide tube 2212 of the atomizer 22a and the air guide tube 2212b of the atomizer 22b are connected to the air outlet 11 through the second air guide hole 122 respectively. At this time, the first air guide hole 121 is blocked, as shown in FIG. Figure 10 shown.

[0090] Further in some embodiments, Figure 17 As shown, the second sealing member 12 also includes a protrusion 123 disposed between the second air guide holes 122 and extending into the air outlet 11. The outer diameter of the protrusion 123 gradually decreases along its extension direction. Furthermore, when the bracket 21 rotates to the second position, the aerosols produced by the multiple atomizers 22 escape from the second air guide holes 122 and then flow along the outer surface of the protrusion 123 into the air outlet 11. This allows the aerosols produced by the multiple atomizers 22 to be more thoroughly mixed in the air outlet 11, improving the taste of the mixed aerosol.

[0091] And, in some embodiments, as Figure 17As shown, the protrusion 123 is hollow, and the first air guide hole 121 is defined by the hollow area of ​​the protrusion 123 .

[0092] In some embodiments, the electrical connection terminals 321 are arranged at intervals along a straight line, and the bracket 21 is configured to be able to move along a straight line. During the movement, one or more atomizers 22 on the bracket 21 are electrically connected to the electrical connection terminals 321 to form a power supply circuit with the battery cell, thereby enabling the battery cell to provide electrical energy to one or more of the atomizers 22.

[0093] like Figure 18 As shown, when the bracket 21 moves to the first position, the two conductive electrodes of the second atomizer 22b are electrically connected to the two middle electrical connection terminals 321b and the electrical connection terminal 321c, thereby establishing a power supply circuit between the second atomizer 22b and the battery cell. At this time, one of the conductive electrodes of the first atomizer 22a abuts the electrical connection terminal 321a, and one of the conductive electrodes of the third atomizer 22c abuts the electrical connection terminal 321d. Neither the first atomizer 22a nor the third atomizer 22c can establish a power supply circuit with the battery cell, and the battery cell only supplies power to the second atomizer 22b.

[0094] When the bracket 21 moves from the first position to the second position along the first direction, as shown in FIG. Figure 19 As shown, the two conductive electrodes of the third atomizer 22c are respectively in contact with the electrical connection terminal 321d and the electrical connection terminal 321c, thereby forming a power supply circuit with the battery cell. Simultaneously, the two conductive electrodes of the second atomizer 22b are respectively in contact with the electrical connection terminal 321b and the electrical connection terminal 321a, thereby forming a power supply circuit with the battery cell. The conductive electrodes of the first atomizer 22a are suspended in the air and cannot form an electrical connection with the battery cell. At this time, the battery cell provides power to the third atomizer 22c and the second atomizer 22b.

[0095] Alternatively, the bracket 21 can also be moved from the first position to the second position along a second direction opposite to the first direction. At this time, the conductive electrode of the third atomizer 22c is suspended in the air and cannot form a power supply circuit with the battery cell, while the first atomizer 22a and the second atomizer 22b can form a power supply circuit with the battery cell through the electrical connection terminal, so that the battery cell supplies power to the first atomizer 22a and the second atomizer 22b.
