[0029] This application provides an electronic atomization apparatus 300. Referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic structural diagram of an electronic atomization apparatus according to an embodiment of this application, and FIG. 2 is a schematic structural diagram of an atomizer of the electronic atomization apparatus shown in FIG. 1.
[0030] The electronic atomization apparatus 300 includes an atomizer 100 for atomizing a liquid matrix to generate an aerosol, and a power supply assembly 200 supplying power to the atomizer 100, where the power supply assembly 200 may be detachably or non-detachably connected to the atomizer 100.
[0031] In this embodiment, the power supply assembly 200 may be detachably connected to the atomizer 100. The power supply assembly 200 includes a battery and a control element. The control element is electrically connected to the battery and controls the battery to supply power to the atomizer 100.
[0032] Referring to FIG. 2 to FIG. 11 or referring to FIG. 12 to FIG. 16, the atomizer 100 is configured to atomize a liquid matrix to generate an aerosol, and includes an atomization core 10, a mounting seat 20, an electrode 30, and a housing 40. The mounting seat 20 is arranged in the housing 40, and the atomization core 10 is arranged in the mounting seat 20. The atomization core 10 is used for atomizing the liquid matrix to generate an aerosol. The atomization core 10 includes an atomization surface 110 for releasing the aerosol, and the atomization surface 110 of the atomization core 10 faces an atomization cavity 23 in the mounting seat 20 and is parallel to a first direction A. The electrode 30 is connected to mounting seat 20 and electrically connected to atomization core 10.
[0033] As shown in FIG. 3, the mounting seat 20 is arranged in the housing 40 and is combined with the housing 40, to define a liquid storage cavity 42. The liquid storage cavity 42 is used for storing a liquid matrix and can supply the liquid to the atomization core 10. The atomization core 10 is used for atomizing the liquid matrix to generate an aerosol in the atomization cavity 23. The mounting seat 20 is provided with an air inlet 221 and an air outlet 212 that communicate with the atomization cavity 23. The housing 40 defines a vapor-gas output channel 44 that is located in the housing 40. The vapor-gas output channel 44 is centrally arranged in the housing 40, communicates with the air outlet 212, and is used for guiding the aerosol in the atomization cavity 23 to an oral cavity of a user.
[0034] Specifically, as shown in FIG. 4, FIG. 5, and FIG. 8, the mounting seat 20 includes a support 21 and a bottom cover 22. The support 21 includes an air outlet 212. The bottom cover 22 includes an air inlet 221. The support 21 and the bottom cover 22 are connected to each other so that an airflow channel extending in the first direction A is defined between the air inlet 212 and the air outlet 221. The support 21 and the bottom cover 22 can be cooperatively connected together in a second direction B substantially perpendicular to the first direction A, and an atomization cavity 23 is defined between the support 21 and the bottom cover 22. The atomization core 10 is positioned between the support 21 and the bottom cover 22, and the atomization surface 110 of the atomization core 10 extends parallel to the first direction A and faces the atomization cavity 23.
[0035] In this embodiment, the support 21 includes a first extension wall 215 extending parallel to the first direction A, the bottom cover 22 includes a second extension wall 223 extending parallel to the first direction A, and the first extension wall 215 and the second extension wall 223 are combined in the second direction B to define the atomization cavity 23.
[0036] The first extension wall 215 and the second extension wall 223 may be snap-fitted, screwed or bonded to be combined in the second direction B, fix the atomization core 10, and define the atomization cavity 23. The first extension wall 215 and the second extension wall 223 may be in the shape of a flat plate, an arc-shaped plate, or the like.
[0037] The support 21 includes a first snap-fit member 211 arranged on the first extension wall 215, and the bottom cover 22 includes a second snap-fit member 222 arranged on the second extension wall 223. The support 21 and the bottom cover 22 are cooperatively connected together through snap-fit between the first snap-fit member 211 and the second snap-fit member 222, and the atomization cavity 23 is defined between the support 21 and the bottom cover 22.
[0038] In this embodiment, the support 21 includes two first snap-fit members 211 and a mounting groove 210 located between the two first snap-fit members 211, and the atomization core 10 is mounted in the mounting groove 210. The mounting seat 20 has a first direction A from the air inlet 221 to the air outlet 212. The mounting groove 210 is used for mounting the atomization core 10 such that the atomization surface 110 of the atomization core 10 faces the atomization cavity 23 and extends parallel to the first direction A.
[0039] In another embodiment, the support 21 and the bottom cover 22 may alternatively be cooperatively connected to each other in the second direction B through another structure and in another connection manner. Details are not described.
[0040] Further, a sealing sleeve 24 is arranged between the support 21 and an inner wall surface of the housing 40, so as to implement hermetical connection. This can prevent liquid leakage between the support 21 and the housing 40. The bottom cover 22 further covers an open end of the housing 40.
[0041] In this embodiment, as shown in FIG. 3 and FIG. 10, the atomization core 10 and the atomization cavity 23 are arranged side by side in the second direction B, and the atomization surface 110 faces the atomization cavity 23. The air inlet 221 and the air outlet 212 both communicate with the atomization cavity 23.
[0042] Referring to FIG. 6 and FIG. 7, the atomization surface 110 may be a plane parallel to the first direction A or a recessed cambered surface. The atomization surface 110 is a recessed cambered surface parallel to the first direction A. It may be understood that, an extension direction of the atomization surface 110 along an axis of the atomization surface is parallel to the first direction A, so that an airflow may directly pass through an area enclosed by the recessed cambered surface, and the airflow can carry away the generated aerosol more quickly and sufficiently. The airflow has a higher content of the aerosol, and has a better taste for the user.
[0043] In this embodiment, the atomization core 10 includes a porous body 11 and a heating body 12. The heating body 12 is combined with the porous body 11. The porous body 11 is used for absorbing and guiding a liquid, and the heating body 12 is used for heating and atomizing the liquid matrix introduced by the porous body 11.
[0044] The porous body 11 may be porous glass, a porous ceramic, or the like, with an inner wall including a network structure with interconnected pores, and has good liquid absorption and liquid guide characteristics. The heating body 12 may be a heating film, a resistance wire, or the like, and is used for heating and atomizing the liquid matrix on a side of the porous body 11 to generate an aerosol.
[0045] The porous body 11 has a first surface 111 and a second surface 112 facing away from the first surface 111. A part of the first surface 111 is the atomization surface 110, and at least a part of the second surface 112 is a liquid absorption surface 113. The atomization surface 110 is a recessed cambered surface, and the liquid absorption surface 113 is an outwardly protruding cambered surface. A thickness between the liquid absorption surface 113 and the atomization surface 110 is substantially uniform, so that it takes approximately the same time for the liquid matrix to move from the liquid absorption surface 113 to the atomization surface 110, and the liquid is guided uniformly, thereby preventing dry burning of the heating body 12 caused by non-uniform liquid guide.
[0046] The liquid absorption surface 113 is an outwardly protruding cambered surface opposite to the atomization surface 110, so that the thickness between the liquid absorption surface 113 and the atomization surface 110 can be substantially uniformly set. In this embodiment, the thickness between the liquid absorption surface 113 and the atomization surface 110 is substantially uniform, which may be understood as that a ratio of a maximum thickness to a minimum thickness is in a range of 1.2 to 1. For example, the ratio of the maximum thickness to the minimum thickness between the liquid absorption surface 113 and the atomization surface 110 is 1.0, 1.04, 1.08, 1.12, 1.16, 1.2, or the like. Within this range, there is no large liquid supply difference in areas between the liquid absorption surface 113 and the atomization surface 110, so that dry burning caused by the liquid supply being not timely can be effectively avoided.
[0047] In this application, the atomization surface 110 is defined as a recessed cambered surface, the liquid absorption surface 113 is defined as an outwardly protruding cambered surface, and the thickness between the liquid absorption surface 113 and the atomization surface 110 is substantially uniform. Therefore, the aerosol generated on a side where the atomization surface 110 is located is more concentrated and can be easily taken away by an airflow to improve the taste while uniform liquid guide between the liquid absorption surface 113 of the porous body 11 and the atomization surface 110 is ensured.
[0048] The first surface 111 further includes two first edge surfaces 114 located on two sides of the atomization surface 110. The heating body 12 includes a heating portion 121 and two electrode portions 122 connected to two ends of the heating portion 121 respectively. The heating portion 121 is combined on the atomization surface 110, and the two electrode portions 122 are combined on the two first edge surfaces 114 respectively, so that the heating portion 121 can operate on the atomization surface 110. The electrode portions 122 are used for electrically connecting to the electrode.
[0049] The two first edge surfaces 114 are cambered surfaces, or the two first edge surfaces 114 are planes. This is not specifically limited in this application.
[0050] The second surface 112 further includes two second edge surfaces 115 located on two sides of the liquid absorption surface 113. The two second edge surfaces 115 are cambered surfaces, or the two second edge surfaces 115 are planes. This is not specifically limited in this application.
[0051] In this embodiment, the two second edge surfaces 115 are planes, and the two second edge surfaces 115 are located in the same plane. The first edge surfaces 114 are parallel to the second edge surfaces 115. The first surface 111 has a length direction and a width direction perpendicular to the length direction. The atomization surface 110 and the two first edge surfaces 114 are arranged in the length direction. Similarly, the liquid absorption surface 113 and the two second edge surfaces 115 are also arranged in the length direction.
[0052] The heating portion 121 includes a heating line or at least two heating lines in parallel connection. The heating line is connected between the two electrode portions 122, and the at least two heating lines are arranged at intervals in the width direction, so that each part of the atomization surface 110 can be heated relatively evenly. That is, a space of the porous body 11 in the width direction can be fully utilized, and the atomization core 10 can achieve greater atomization power by arranging a plurality of heating lines in parallel connection.
[0053] Further, as shown in FIG. 3 to FIG. 5, the air inlet 221 is provided at a bottom of the bottom cover 22, and the air inlet 221 and the atomization core 10 are arranged in a staggered manner in the first direction A. That is, projections of the air inlet 221 and the atomization core 10 in a plane perpendicular to the first direction A do not overlap each other, that is, the atomization core 10 is positioned to avoid the air inlet 221 in the first direction A. The atomization surface 110 of the atomization core 10 partially defines the atomization cavity 23, so that the airflow can cross the atomization surface 110 more smoothly.
[0054] In this embodiment, the vapor-gas output channel 44 is centrally arranged in the housing 40, and the vapor-gas output channel 44 communicates with the air outlet 212. That is, the air outlet 212 and the air inlet 221 are aligned in the first direction A, so that the airflow channel between the air outlet 212 and the air inlet 221 is a direct flow channel. Therefore, this can eliminate a turning structure in an air channel, guide the airflow more efficiently and smoothly, effectively shorten a distance from the aerosol to an oral cavity of a user and effectively reduce the formation of macromolecular particles in the aerosol, and enables the aerosol to enter the oral cavity of the user at a higher temperature, thereby improving a taste.
[0055] Referring to FIG. 8, the first snap-fit member 211 and the second snap-fit member 222 are separately one of a snap-fit post and a snap-fit port, and the snap-fit post is snap-fitted with the snap-fit port, or the first snap-fit member 211 and the second snap-fit member 222 may be two snap-fit posts that are snap-fitted. The first snap-fit member 211 and the second snap-fit member 222 may be snap-fitted in the first direction A, or the first snap-fit member 211 and the second snap-fit member 222 may be snap-fitted in the second direction B, or the first snap-fit member and the second snap-fit member may be snap-fitted in a direction different from the first direction A and the second direction B.
[0056] The support 21 has a width direction and a thickness direction perpendicular to the width direction, and a width dimension of the support 21 in the width direction is greater than a thickness dimension thereof in the thickness direction. The first direction A is perpendicular to the width direction and the thickness direction, and the second direction B is parallel to the width direction or the thickness direction.
[0057] As shown in FIG. 10, in an embodiment, the atomization core 10 and the atomization cavity 23 are arranged side by side in the thickness direction of the support 21, and the atomization surface 110 of the atomization core faces the atomization cavity 23 in the thickness direction. First, there is no other structure that prevents the atomization core 10 from being mounted in the mounting groove 210 in the thickness direction (second direction B), thereby facilitating the convenient assembly between the atomization core 10 and the mounting groove 210 and the mounting of the atomization core 10. Then the support 21 and the bottom cover 22 can be conveniently cooperatively connected in the thickness direction. The entire assembly process is very concise and clear, which facilitates automatic assembly of the atomizer 100 with the assistance of a machine, namely automatic assembly of the atomizer 100.
[0058] There are at least two first snap-fit members 211. In the width direction, the at least two first snap-fit members 211 are located on two sides of the mounting groove 210 respectively, and the at least two first snap-fit members 211 are snap-fitted with the second snap-fit member 222 in the thickness direction. The atomization core 10 can be stably fixed by a lateral tension provided through lateral snap-fit between the first snap-fit members 211 and the second snap-fit member 222.
[0059] The support 21 and the bottom cover 22 can be mounted in the thickness direction or in a direction opposite to the first direction A, so as to implement the snap-fit between the first snap-fit members 211 and the second snap-fit member 222 in the thickness direction.
[0060] For example, the second snap-fit member 222 is an open-loop snap-fit port in the bottom cover 22, and has an opening at a top of the bottom cover 22 facing the support 21. The first snap-fit members 211 can be mounted with the second snap-fit member 222 in the direction opposite to the first direction A, to implement snap-fit in the thickness direction.
[0061] Alternatively, the second snap-fit member 222 is a closed-loop snap-fit port in the bottom cover 22, and the first snap-fit members 211 are mounted with the second snap-fit member 222 in the thickness direction, to implement snap-fit in the thickness direction.
[0062] As shown in FIG. 4 and FIG. 8, a liquid inlet groove 213 is provided in a side of the support 21 that faces away from the first snap-fit member 211 in the thickness direction of the support, and the liquid inlet groove 213 extends from a top end surface of the support 21 to a bottom end surface of the support 21 and communicates with the mounting groove 210. The liquid inlet groove 213 has a notch in a peripheral surface of the support 21, and the notch is sealed by the sealing sleeve between the support 21 and the housing 40. The notch of the liquid inlet groove 213, which is located in the support 21 and faces the liquid storage cavity 42, communicates with the liquid storage cavity 42, and then the liquid matrix in the liquid storage cavity 42 can be supplied, through the liquid inlet groove 213, to the atomization core 10 arranged in the mounting groove 210.
[0063] The liquid inlet groove 213 is provided in the side of the support 21 that faces away from the first snap-fit member 211 in the thickness direction of the support, so as to reduce a dimension requirement for the support 21. This makes the support 21 thinner in the thickness direction, and facilitates miniaturization and light weight of the atomizer 100.
[0064] In this embodiment, as shown in FIG. 8 and FIG. 9, the second snap-fit member 222 is arranged on the second extension wall 223 of the bottom cover 22 parallel to the first direction A. The second snap-fit member 222 may be a snap-fit port or a snap-fit post arranged on the second extension wall 223.
[0065] The bottom cover 22 includes a second extension wall 223 and two blocking walls 224 extending from the second extension wall 223 toward the mounting groove 210. The second extension wall 223 and the two blocking walls 224 partially define the atomization cavity 23. That is, the structure including the second extension wall 223 and the two blocking walls 224 is buckled on the atomization surface 110 and partially defines the atomization cavity 23 in cooperation with the atomization surface 110. The two blocking walls 224 can guide the airflow entering from the air inlet 221 to pass through the atomization cavity 23 directly to the air outlet 212.
[0066] The bottom cover 22 further includes a bottom wall 225, and the bottom wall 225 is provided with two electrode mounting holes 226. The two electrode mounting holes 226 are respectively located outside sides of the two blocking walls 224 that face away from each other, and electrodes 30 mounted in the electrode mounting holes 226 are isolated from the atomization cavity 23 through the two blocking walls 224. Therefore, the atomization cavity 23 is confined in a small space through which the airflow channel flows straight, and the aerosol is prevented from spreading to a surrounding space, which otherwise is susceptible to formation of turbulence. In addition, aerosol droplets in the atomization cavity 23 are prevented from polluting the electrodes 30. The atomization core 10 comes into contact with the electrodes 30 by the lateral tension of the first snap-fit members 211 and the second snap-fit member 222, thereby implementing electrical connection.
[0067] As shown in FIG. 8 to FIG. 10, the electrodes 30 extend into the bottom cover 22 from the bottom wall 225 of the bottom cover 22. The atomization core 10 includes a heating body 12 combined on the atomization surface 110, and the heating body 12 is in contact with the electrodes 30 in the second direction B to implement electrical connection.
[0068] Further, the atomizer 100 further includes an elastic sealing member 50. At least a part of the elastic sealing member 50 is arranged between the support 21 and a side of the atomization core 10 that faces away from the atomization surface 110, and the elastic sealing member is used for applying an elastic acting force to the atomization core 10 toward the electrodes 30, so as to implement elastic contact between the electrodes 30 and the atomization core 10 by using a rebound force of the elastic sealing member 50. This can prevent the electrodes 30 and the atomization core 10 from being damaged due to hard contact. That is, at least a part of the elastic sealing member 50 and the electrodes 30 are in corresponding contact with surfaces of two opposite sides of the atomization core 10, and the atomization core 10 is located between the at least a part of the elastic sealing member 50 and the electrodes 30. The lateral tension of the first snap-fit members 211 and the second snap-fit member 222 causes the electrodes 30, the atomization core 10, and the elastic sealing member 50 to be all stressed. The elastic sealing member 50 can be elastically deformed to prevent an excessive contact pressure between the electrodes 30 and the atomization core 10. This can ensure reliability of contact between the electrodes 30 and the atomization core 10, and avoid damage to the electrodes and the atomization core caused by an excessive contact pressure, thereby protecting the electrodes 30 and the atomization core 10.
[0069] Referring to FIG. 10 and FIG. 11, the elastic sealing member 50 includes a protruding portion 52 arranged on a side of the atomization core 10 that faces away from the electrodes 30. The protruding portion 52 is sandwiched between the atomization core 10 and a bottom wall of the mounting groove 210, and the protruding portion 52 is used for providing a rebound force. In some examples, there are at least two protruding portions 52, which are located at corresponding positions on the atomization core 10 that face away from the two electrodes 30.
[0070] Further, the elastic sealing member 50 further includes a circumferential sealing side wall 51 and an annular protruding rib 53 arranged on the circumferential sealing side wall 51. The circumferential sealing side wall 51 is connected to a peripheral side of the protruding portion 52, and the circumferential sealing side wall 51 surrounds a circumferential side surface of the atomization core 10 that is connected to the atomization surface 110. The annular protruding rib 53 closely abuts against a side wall of the mounting groove 210, so as to implement the sealing between the atomization core 10 and the mounting groove 210 to prevent liquid leakage.
[0071] Referring to FIG. 12 to FIG. 16, in another embodiment, the atomization core 10 and the atomization cavity 23 are arranged side by side in the width direction of the support 21, and the atomization surface 110 faces the atomization cavity 23 in the width direction. There may alternatively be at least two first snap-fit members 211. The at least two first snap-fit members 211 are located on two sides of the mounting groove 210 respectively in the thickness direction and are snap-fitted with the second snap-fit member 222 in the width direction.
[0072] A liquid inlet hole 214 is provided in a side of the support 21 that faces away from the first snap-fit member 211 in the width direction of the support, and the liquid inlet hole 214 extends from a top end surface of the support 21 to a bottom end surface of the support 21 and communicates with the mounting groove 210. The liquid inlet hole 214 further communicates with the liquid storage cavity 42.
[0073] It is defined that the side of the support 21 that faces away from the first snap-fit member 211 in the width direction of the support is provided with the liquid inlet hole 214, to fully utilize the dimension of the support 21 in the width direction, so that the dimension of the liquid inlet hole 214 can be set relatively large, to sufficiently supply a liquid to the atomization core 10.
[0074] The electrodes 30 extend into the bottom cover 22 from the bottom wall 225 of the bottom cover 22, and are in contact with the heating body 12 in the second direction B to implement electrical connection, and the elastic sealing member 50 is arranged at least between the support 21 and the side of the atomization core 10 that faces away from the atomization surface 110. Details are not described.
[0075] Different from a case in the prior art, this application discloses the electronic atomization apparatus, the atomizer and the mounting seat thereof. The mounting seat is defined as having the first direction from the air inlet of the bottom cover to the air outlet of the support, and therefore, the support and the bottom cover are cooperatively connected together through the snap-fit between the first snap-fit members and the second snap-fit member, so that the atomization surface of the atomization core arranged in the mounting groove of the support faces the atomization cavity defined between the support and the bottom cover and is parallel to the first direction. That is, the airflow channel between the air outlet and the air inlet is a direct flow channel and passes through the atomization cavity. This can eliminate a turning structure in an air channel, guide the airflow more efficiently and smoothly, effectively shorten a distance from the aerosol to an oral cavity of a user and effectively reduce the formation of macromolecular particles in the aerosol, and enables the aerosol to enter the oral cavity of the user at a higher temperature, thereby improving a taste.
[0076] The above are merely the embodiments of this application and do not constitute a limitation on the patent scope of this application. Any equivalent structure or equivalent process change made by using the content of the specification and the accompanying drawings of this application, which is directly or indirectly applied to other related technical fields, should similarly fall within the protection scope of the patent of this application.
