An embodiment of the application provides an atomization device. With reference to FIG. 1 and FIG. 2, the atomization device includes an atomizer holder 11, a power supply assembly 20 and a rotation assembly 30.
With reference to FIG. 3, FIG. 4 and FIG. 10, the atomizer holder 11 is configured to accommodate multiple atomizers 12.
With reference to FIG. 7 and FIG. 8, the rotation assembly 30 includes a rotation body 31 and a conductive structure 32, the conductive structure 32 is arranged on the rotation body 31, the conductive structure 32 is electrically connected to the power supply assembly 20, at least one of the rotation body 31 and the atomizer holder 11 is rotatable relative to each other, and at least one of the rotation body 31 and the power supply assembly 20 is rotatable relative to each other, to switch a position of the conductive structure 32 relative to each of the atomizers 12.
Another embodiment of the application provides an electronic atomization apparatus, the electronic atomization apparatus includes multiple atomizers 12 and the atomization device described in any embodiment of the application. At least one of the atomizers 12 is accommodated in the atomization device.
Specifically, the atomizer holder 11 is configured to mount the atomizers 12. An aerosol-generating matrix is stored in each of the atomizers 12, and each of the atomizers 12 may atomize the aerosol-generating matrix to form an aerosol in an operation state, so that the user may inhale the aerosol.
The conductive structure 32 is a structure capable of conducting electricity. The conductive structure may be an electrode post, an electrode elastic sheet or the like, and may be configured to provide power of the power supply assembly 20 to at least one of the atomizers 12 by electrically connecting to the power supply assembly 20, so that the at least one atomizer 12 may atomize the aerosol-generating matrix by generating heat when the atomizer 12 is powered on.
At least one of the rotation body 31 and the atomizer holder 11 is rotatable relative to each other. According to actual situations, in some embodiments, the rotation body 31 and the atomizer holder 11 are relatively rotatable by rotating the rotation body 31. In some other embodiments, the rotation body 31 and the atomizer holder 11 are relatively rotatable by rotating the atomizer holder 11. In some other embodiments, the rotation body 31 and the atomizer holder 11 are relatively rotatable by rotating either one of the atomizer holder 11 and the rotation body 31.
At least one of the rotation body 31 and the power supply assembly 20 is rotatable relative to each other. According to actual situations, in some embodiments, the rotation body 31 and the power supply assembly 20 are relatively rotatable by rotating the rotation body 31. In some other embodiments, the rotation body 31 and the power supply assembly 20 are relatively rotatable by rotating the power supply assembly 20. In some other embodiments, the rotation body 31 and the power supply assembly 20 are relatively rotatable by rotating either one of the power supply assembly 20 and the rotation body 31.
[0046] Further, since the conductive structure 32 is arranged on the rotation body 31, at least one of the conductive structure 32 and the atomizer holder 11 is rotatable relative to each other, and at least one of the conductive structure 32 and the power supply assembly 20 is rotatable relative to each other, then the position of the conductive structure 32 relative to each of the atomizers 12 may be changed.
[0047] A respective one of the atomizers 12 electrically connected to the power supply module 20 may be switched to by switching the position of the conductive structure 32 relative to each of the atomizers 12, that is, the power supply module 20 may be selectively electrically connected to a respective one of the atomizers 12 according to requirements, and thus different atomizers 12 may be switched to perform atomization operations.
[0048] In the atomization device according to the embodiment of the application, at least one of the rotation body 31 and the atomizer holder 11 is rotatable relative to each other, and at least one of the rotation body 31 and the power supply assembly 10 is rotatable relative to each other, to switch the position of the conductive structure 32 relative to each of the atomizers 12. Therefore, when multiple atomizers 12 are arranged in the atomizer holder 11, then after an aerosol-generating matrix stored in one of the atomizers 12 is exhausted, another one of the atomizers 12 may be switched to by the relative rotation between the rotation body 31 and the atomizer holder 11, to continue to use the another atomizer 12, and it is not needed to replace the atomizers 12 due to the fact that the aerosol-generating matrix in one of the atomizers 12 is exhausted, so that operations of the electronic atomization apparatus may be more convenient and may be convenient for the user to use.
[0049] In an embodiment, with reference to FIG. 6, FIG. 7 and FIG. 8, the rotation body 31 is provided with a connection component 31a to which the atomizer holder 11 and the power supply assembly 20 are connected. At least one of the rotation body 31 and the atomizer holder 11 is rotatable relative to each other and at least one of the rotation body 31 and the power supply assembly 20 is rotatable relative to each other by taking the connection component 31a as a rotation center.
[0050] Specifically, the atomizer holder 11 and the power supply assembly 20 are connected together by the connection component 31a. On one hand, it may facilitate mounting the atomizer holder 11, the rotation body 31 and the power supply assembly 20, while it may facilitate mutual rotation of the structures relative to each other.
[0051] In an embodiment, the user switches the position of the conductive structure 32 relative to each of the atomizers 12 by rotating the rotation body 31. It may facilitate exposure of the rotation body 31 by forming the connection component 31a, and it may facilitate the user to directly rotate the rotation body 31, thereby facilitating switching the atomizer 12 in an atomization state.
[0052] A specific structural form of the connection component 31a is not limited. For example, the connection component 31a is a connection hole or a connection member provided with a mounting hole.
[0053] Further, a manner in which the atomizer holder 11 and the power supply assembly 20 are connected via the connection component 31a may be set according to actual situations.
[0054] Exemplarily, the connection component 31a is a connection hole, and the atomizer holder 11 and the power supply assembly 20 are connected by a cross screw and an anti-loosening nut passing through the connection hole.
[0055] Further, according to a specific arrangement form of the electronic atomization apparatus, other rotation manners may be also used for the relative rotation between the rotation body 31 and the atomizer holder 11, and the relative rotation between the rotation body 31 and the power supply assembly 20.
[0056] Exemplarily, with reference to FIG. 13, the electronic atomization apparatus further includes a mouthpiece assembly 40, the rotation assembly 30 further includes a first transmission assembly 33, and opposite ends of the first transmission assembly 33 are connected to the rotation body 31 and the mouthpiece assembly 40 respectively, to drive one of the atomizer holder 11, the rotation body 31 and the mouthpiece assembly 40 to move, to switch the position of the conductive structure 32 relative to each of the atomizers 12.
[0057] Specifically, the mouthpiece assembly 40 is an assembly from which the electronic atomization apparatus exports the generated aerosol, and is an area for the user to suck. The mouthpiece assembly 40 is connected to the rotation body 31 through the first transmission assembly 33, so that the user may switch the atomizer 12 in an atomization state by driving one of the atomizer holder 11, the rotation body 31 and the mouthpiece assembly 40 to move. Therefore, the rotation body 31 may be accommodated in the electronic atomization apparatus without exposing the rotation body 31, which may improve protection of the rotation body 31.
[0058] It should be noted that the mouthpiece assembly 40 may be an integrally molded structure.
[0059] According to actual situations, the mouthpiece assembly 40 may also adopt a split structure.
[0060] For example, with reference to FIG. 9, the mouthpiece assembly 40 includes a fixing cover 41 and a rotation cover 42, the rotation cover 42 is provided with a mist outlet and is rotatably arranged on the fixing cover 41, and the fixing cover 41 is arranged on the atomizer holder 11. Opposite ends of the first transmission assembly 33 are connected to the rotation body 31 and the rotation cover 42 respectively, the atomizers 12 are arranged around a circumferential direction of the first transmission assembly 33, and the rotation cover 42 rotates to drive the rotation body 31 to rotate relative to the atomizer holder 11. Therefore, on one hand, it may facilitate the rotation cover 42 to drive the rotation body 31 to rotate, and on the other hand, mounting stability of the rotation cover 42 may also be improved by providing the fixing cover 41.
[0061] Furthermore, according to actual situations, the electronic atomization apparatus may also adopt other rotation manners to meet actual demands.
[0062] Exemplarily, the electronic atomization apparatus further includes a bottom cover located at a side of the power supply assembly 20 away from the atomizer holder 11, the rotation assembly 30 further includes a second transmission assembly, opposite ends of the second transmission assembly are connected to the rotation body 31 and the bottom cover respectively, to drive one of the atomizer holder 11, the rotation body 31 and the bottom cover to move, to switch the position of the conductive structure 32 relative to each of the atomizers 12. Therefore, switching of the atomizer 12 in an atomization state may be achieved.
[0063] A number of conductive structures 32 may be set according to actual situations, and mating manners of the conductive structures 32 with the atomizers 12 may also be set according to actual situations.
[0064] For example, the rotation assembly 30 includes a set of conductive structures 32, and a relative rotation between the rotation body 31 and the atomizer holder 11 and a relative rotation between the rotation body 31 and the power supply assembly 20 switch respective electrical connection states of the conductive structures 32 with each of the atomizers 12.
[0065] Specifically, one of multiple atomizers 12 may be selectively electrically connected by only one of the conductive structures 32, so that the one atomizer 12 may be selectively electrically connected to the power supply assembly 20. The power supply assembly 20 supplies power to the atomizer 12, so that the atomizer 12 may atomize the aerosol-generating matrix. Therefore, after an aerosol-generating matrix in one of the atomizers 12 is exhausted, the user may make the power supply assembly 20 electrically connected to another one of the atomizers 12 by the relative rotation between the rotation body 31 and the atomizer holder 11 and the relative rotation between the rotation body 31 and the power supply assembly 20, so that the another atomizer 12 continues to perform atomization operations.
[0066] For another example, the rotation assembly 30 includes multiple sets of conductive structures 32, and a relative rotation between the rotation body 32 and the atomizer holder 11 and a relative rotation between the rotation body 31 and the power supply assembly 20 switch respective electrical connection states of the conductive structures 32 with at least one of the atomizers 12.
[0067] Specifically, the rotation assembly 30 includes at least one set of conductive structures 32. In an electrically connected state, a set of conductive structures 32 may be electrically connected to only one of the atomizers 12, so that the only one atomizer 12 operates.
[0068] According to actual situations, it is also possible that multiple sets of conductive structures 32 are electrically connected to at least two of the atomizers 12, so that multiple atomizers 12 operate simultaneously in the electrically connected state. Therefore, a mist output amount may be increased when the electronic atomization apparatus operates. It is also possible that different aerosol-generating matrices are stored in different atomizers 12, so that the user's requirement of inhaling aerosols with mixed flavors may be met. Of course, the same aerosol-generating matrix may also be stored in different atomizers 12.
[0069] In an embodiment, with reference to FIG. 7, the rotation body 31 is provided with an orifice 31b communicated with an outside atmosphere, each of the atomizer 12 is provided with an air passage through which an airflow flows, and the relative rotation between the rotation body 31 and the atomizer holder 11 and the relative rotation between the rotation body 31 and the power supply assembly 20 switch a respective communication state of the orifice 31b with the air passage of each of the atomizers 12.
[0070] Specifically, the orifice 31b may allow an external airflow to flow through it, so that after the airflow passes through the atomizer 12 in the atomization state, the airflow may bring the aerosol formed by atomization of the atomizer 12 out, for the user to inhale.
[0071] It is to be noted that after the user switches the atomizer 12 in an atomization state by the relative rotation between the rotation body 31 and the atomizer holder 11 and the relative rotation between the rotation body 31 and the power supply assembly 20, a respective one of air passages of the atomizers 12 with which the orifice 31b is communicated is also switched there-along. That is, when the user switches the power supply assembly 20 from being electrically connected to one of the atomizers 12 to being electrically connected to another one of the atomizers 12 by rotation, and accordingly the orifice 31b is communicated with the air passage of the atomizer 12 in the electrically connected state after switching. Therefore, it may facilitate the airflow to bring the aerosol generated by the atomizer 12 in the atomization state out.
[0072] In an embodiment, the conductive structure 32 is rotatable from a first orientation to a second orientation and then to a third orientation relative to the atomizer holder 11.
[0073] When the conductive structure 32 is located in the first orientation relative to the atomizer holder 11, at least one of the atomizers 12 is electrically connected to the conductive structure 32. When the conductive structure 32 is located in the second orientation relative to the atomizer holder 11, the atomizers 12 are arranged to avoid the conductive structure 32. When the conductive structure 32 is located in the third orientation relative to the atomizer holder 11, another one of the atomizers 12 is electrically connected to the conductive structure 32.
[0074] Specifically, the relative rotation between the rotation body 31 and the atomizer holder 11 and the relative rotation between the rotation body 31 and the power supply assembly 20 may drive the conductive structure 32 to rotate relative to the atomizer holder 11, and the position of the conductive structure 32 is switched from the first orientation to the second orientation and then to the third orientation.
[0075] The first orientation, the second orientation and the third orientation are positions of the conductive structure 32 relative to the atomizer holder 11. Taking FIG. 3 as an example, when the conductive structure 32 is located at the position a of FIG. 3 to be electrically connected with the atomizer 12 at the position a, the conductive structure 32 is located in the first orientation relative to the atomizer holder 11. When the conductive structure 32 is located at the position c of FIG. 3 to be electrically connected with the atomizer 12 at the position c, the conductive structure 32 is located in the third orientation relative to the atomizer holder 11. When the conductive structure 32 is located between the position a and position c of FIG. 3, for example, at the position b, the conductive structure 32 is not electrically connected to any of the atomizers 12. That is, when the conductive structure 32 is located in the first orientation and the third orientation respectively, the conductive structure 32 is electrically connected to a respective atomizer 12. However, the conductive structure 32 is electrically connected to different atomizers 12. When the conductive structure 32 is located in the second orientation, the conductive structure 32 avoids the atomizers 12, that is, the conductive structure 32 is not electrically connected to any of the atomizers 12.
[0076] Therefore, during the relative rotation between the rotation body 31 and the atomizer holder 11, the conductive structure 32 is located in the second orientation. Since the conductive structure 32 is separated from the atomizer holder 11, friction between the conductive structure 32 and the atomizer holder 11 may be avoided. On one hand, a frictional resistance during rotation of the rotation body 31 may be reduced, so that the rotation is labor-saving. On the other hand, a risk of loss caused by friction between the conductive structure 32 and the atomizer holder 11 may also be reduced.
[0077] It should be noted that a specific implementation of switching the conductive structure 32 among the first orientation, the second orientation and the third orientation by the relative rotation between the rotation assembly 30 and the atomizer holder 11, may be set according to actual situations.
[0078] Exemplarily, with reference to FIG. 14 and FIG. 15, the atomizer holder 11 is provided with a first mating surface 11a, the rotation body 31 is provided with a second mating surface 31c slidably mating with the first mating surface 11a, and the first mating surface 11a and the second mating surface 31c are arranged opposite to each other along an axial direction of the electronic atomization apparatus.
[0079] The second mating surface 31c is provided with a first position 31ca, a second position 31cb and a third position 31cc. When the first mating surface 11a is located at the first position 31ca, the conductive structure 32 is located in the first orientation relative to the atomizer holder 11. When the first mating surface 11a is located at the second position 31cb, the conductive structure 32 is located in the second orientation relative to the atomizer holder 11. When the first mating surface 11a is located at the third position 31cc, the conductive structure 32 is located in the third orientation relative to the atomizer holder 11.
[0080] The first position 31ca, the second position 31cb and the third position 31cc are positions corresponding to rotation of the second mating surface 31c from the first orientation to the third orientation relative to the atomizer holder 11. The first position 31ca, the second position 31cb and the third position 31cc are sequentially distributed along a circumferential direction of the atomizer holder 11. During a relative rotation between the atomizer holder 11 and the rotation body 31 with a preset angle, the first mating surface 11a slides from the first position 31ca to the second position 31cb of the second mating surface 31c and slides from the second position 31cb to the third position 31cc. The rotation body 31 and the atomizer holder 11 move close to or far away from each other along an axial direction of the atomizer holder 11 by changing different positions where the first mating surface 11a relatively mates with the second mating surface 31c, thereby avoiding the conductive structure 32.
[0081] Of course, in other embodiments, it is also possible that the second mating surface 31c may be formed on the atomizer holder 11, and the first mating surface 11a may be formed on the rotation body 31.
[0082] In an embodiment, with reference to FIG. 11, FIG. 12, FIG. 14 and FIG. 15, the second mating surface 31c is provided with multiple low-position surfaces 31cd arranged at intervals along a circumferential direction thereof, and a high-position surface 31ce is connected between adjacent low-position surfaces 31cd. When the first mating surface 11a mates with the low-position surface 31cd, the conductive structure 32 is located in the first orientation or the third orientation relative to the atomizer holder 11. When the first mating surface 11a mates with the high-position surface 31ce, the conductive structure 32 is located in the second orientation relative to the atomizer holder 11.
[0083] It should be noted that when the conductive structure 32 rotates from the first orientation to the second orientation and then to the third orientation relative to the atomizer holder 11, the first mating surface 11a slides from one of the low-position surfaces 31cd of the second mating surface 31c to a next one of the low-position surfaces 31cd through a respective one of high-position surfaces 31ce, here one of the low-position surfaces 31cd is the first position 31ca of the second mating surface 31c, a next one of the low-position surfaces 31cd is the third position 31cc of the second mating surface 31c, and a respective one of high-position surfaces 31ce is the second position 31cb of the second mating surface 31c. That is, the low-position surface 31cd, the high-position surface 31ce and the low-position surface 31cd sequentially connected correspond to the first position 31ca, the second position 31cb and the third position 31cc of a unit exactly.
[0084] In the embodiment, the low-position surfaces 31cd and the high-position surfaces 31ce are provided so that when the first mating surface 11a slides to the low-position surface 31cd, the atomizer holder 11 abuts against the rotation body 31 along the axial direction of the electronic atomization apparatus, such that a respective one of the atomizers abuts against the conductive structure 32 to form an electrical connection. When the first mating surface 11a slides to the high-position surface 31ce, the atomizer holder 11 and the rotation body 31 relatively slide along the axial direction of the electronic atomization apparatus, so that the atomizer holder 11 avoids the conductive structure 32.
[0085] The high-position surface 31ce may have a triangular shape, or the high-position surface 31ce may have a curved surface or a wavy shape, which is not solely limited here. In an embodiment, with reference to FIG. 3 and FIG. 5, the second mating surface 31c includes a first protrusion 34 and a second protrusion 35, and the first protrusion 34 and the second protrusion 35 are located at opposite sides of the conductive structure 32 along a rotation direction respectively.
[0086] When the first mating surface 11a is located at the first position, the first protrusion 34 and the second protrusion 35 are located at opposite sides of one of the atomizers 12 along the rotation direction, and the conductive structure 32 is located in the first orientation relative to the atomizer holder 11.
[0087] When the first mating surface 11a is located at the second position, the first protrusion 34 and the second protrusion 35 push up an adjacent atomizer 12 along the axial direction, and the conductive structure 32 is located in the second orientation relative to the atomizer holder 11.
[0088] When the first mating surface 11a is located at the third position, the first protrusion 34 and the second protrusion 35 are located at opposite sides of another one of the atomizers 12 along the rotation direction, and the conductive structure 32 is located in the third orientation relative to the atomizer holder 11.
[0089] Specifically, the rotation direction refers to a direction along which the rotation body 31 rotates about a rotation axis, and opposite sides along the rotation direction refer to a front side along the rotation direction and a rear side along the rotation direction.
[0090] The rotation body 31 and the atomizer holder 11 relatively rotate, so that the first mating surface 11a may be switched among the first position, the second position and the third position. When the first mating surface 11a rotates from the first position to the third position, the first mating surface 11a passes through the second position.
[0091] When the first mating surface 11a is located at the first position and the third position respectively, neither the first protrusion 34 nor the second protrusion 35 comes into contact with the atomizers 12, which may facilitate electrical connections between the atomizers 12 and the conductive structure 32.
[0092] When the first mating surface 11a is located at the second position, the first protrusion 34 and the second protrusion 35 push up the adjacent atomizer 12 along the axial direction, so that the atomizer 12 may be separated from the conductive structure 32, such that the atomizer 12 does not come into contact with the conductive structure 32, and thus the conductive structure 32 may not be electrically connected to all the atomizers 12.
[0093] In an embodiment, with reference to FIG. 7 and FIG. 8, the rotation assembly 30 includes a conductive ring 321 configured for electrical connection and arranged at a side of the rotation body 31 close to the power supply assembly 20, the power supply assembly 20 includes a conductive member arranged at a side of the power supply assembly 20 close to the rotation body 31, and the conductive ring 321 is electrically connected to the conductive member.
[0094] Specifically, the conductive ring 321 is arranged at the side of the rotation body 31 close to the power supply assembly 20, and the conductive ring 321 is configured to be electrically connected to the conductive member of the power supply assembly 20. The conductive ring 321 is an annular conductive structure 32 extending along the rotation direction, and the conductive ring 321 is electrically connected to the conductive member of the power supply assembly 20, so that the conductive member of the power supply assembly 20 may always keep electrical-signal connection with the conductive ring 321 during the relative rotation between the rotation body 31 and the power supply assembly 20, and stability of current transmission may be ensured.
[0095] In an embodiment, the conductive structure 32 is a conductive elastic pin telescopically arranged on the rotation body 31. Therefore, a friction state between the conductive structure 32 and the atomizer holder 11 may be improved.
[0096] A specific implementation of electrically connecting the conductive structure 32 to the atomizers 12 may be set according to actual situations.
[0097] For example, a signal contact is formed at an end of each of the atomizers 12 close to the rotation assembly 30, and when the rotation body 31 rotates, the conductive structure 32 contacts any one of signal contacts, to be in electrical-signal connection with a corresponding one of the atomizers 12. Therefore, the conductive structure 32 may selectively come into contact with the signal contact of each of the atomizers 12, to achieve electrical-signal connection with a corresponding atomizer 12.
[0098] In an embodiment, with reference to FIG. 7, the rotation assembly 30 further includes first magnetic attraction members 36 arranged at a side of the rotation body 31 close to the atomizer holder 11, second magnetic attraction members are formed at an end of the atomizer holder 11 close to the rotation assembly 30, and the first magnetic attraction members 36 rotate with the rotation body 31, to switch magnetic attraction and mating between the first magnetic attraction members 36 and the respective second magnetic attraction members.
[0099] Specifically, the first magnetic attraction member 36 and the second magnetic attraction member are structures capable of achieving magnetic attraction and mating. For example, the first magnetic attraction member 36 is a magnet, and the second magnetic attraction member is a metal material capable of achieving magnetic attraction and mating with the magnet.
[00100] The first magnetic attraction member 36 and the second magnetic attraction members are provided so that when the conductive structure 32 is located in the first orientation and the third orientation, stability of the electrical connection between the conductive structure 32 and the atomizers 12 may be improved, and an atomization process of an atomization core may be more stable.
[00101] Furthermore, when the conductive structure 32 is located in the second orientation, the first magnetic attraction member 36 and the second magnetic attraction members are separated from each other.
[00102] In a specific embodiment, the electronic atomization apparatus further includes an air pressure sensor, and an air passage silica gel arranged between the power supply assembly 20 and the rotation assembly 30. The air pressure sensor is arranged at a side of the air passage silica gel away from the rotation assembly 30, the air passage silica gel is provided with a first air passage port and a second air passage port, the first air passage port is communicated with the orifice 31b, and the second air passage port extends to the air pressure sensor. When the user inhales so that the air pressure sensor senses an inhalation airflow, the electronic atomization apparatus is started to allow the power supply assembly 20 to supply power to the atomizers 12.
