Description

Technical Field

[0001] This invention relates to the field of electronic atomization, and more particularly to an electronic atomization device and its atomizer. Background Technology

[0002] Electronic atomizing devices generally include an atomizer, a power supply, and a control circuit. The atomizer comprises a liquid reservoir, an airflow channel, and an atomizing coil. The airflow channel includes an inlet channel, an atomization chamber, and an outlet channel. Liquid from the reservoir flows to the atomizing coil. When the user inhales, the control circuit controls the power supply to provide electrical energy, heating the atomizing coil and generating an aerosol in the atomization chamber. Air enters through the inlet channel, carrying the aerosol from the atomization chamber out through the outlet channel. In related technologies, the cross-section of the inlet channel is usually uniformly set. If the cross-sectional size is too large, the airflow resistance is too small, affecting the inhalation effect. If the cross-section is too small, the molding die for the inlet channel is prone to deformation or breakage during the one-piece molding process, making it difficult to ensure the consistency of the shape and size of the inlet channel during mass production.

[0050] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0051] It should be understood that terms such as "front," "rear," "left," "right," "upper," "lower," "first," and "second" are merely for the convenience of describing the technical solutions of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore should not be construed as limitations on the present invention. It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0052] Figure 1 and Figure 2 An electronic atomizing device according to some embodiments of the present invention is shown. This electronic atomizing device may be a handheld rod-shaped structure for a user to inhale aerosols. As shown, the electronic atomizing device may include an atomizer 1 and a power supply 2 that cooperates with the atomizer 1. The atomizer 1 can be used to store and heat the atomized liquid aerosol generating matrix, such as a medicinal liquid, and to export the aerosol. The power supply 2 can be used to supply power to the atomizer 1. In some embodiments, the atomizer 1 and the power supply 2 may both be generally elliptical cylindrical and are mechanically and electrically connected together axially. In some embodiments, the atomizer 1 and the power supply 2 may be detachably connected together by magnetic attraction. It is understood that the atomizer 1 and the power supply 2 are not limited to being elliptical cylindrical; they may also be cylindrical with a circular, racetrack-shaped, or irregular cross-section, or non-cylindrical.

[0053] like Figures 3 to 7 As shown, in some embodiments, the atomizer 1 may include an atomizing body 100 and a housing 20 sleeved on the atomizing body 100 along the longitudinal axis X, with a liquid storage chamber 70 formed between the atomizing body 100 and the housing 20. The liquid storage chamber 70 is used to contain a liquid aerosol generating matrix, the atomizing body 100 is used to heat the liquid aerosol generating matrix in the liquid storage chamber 70 to generate aerosol and to mix the aerosol with the surrounding ambient air, and the housing 20 is used to discharge the aerosol-air mixture and protect the atomizing body 100.

[0054] In some embodiments, the housing 20 may include an elongated flat outer shell 21 and an air guide pipe 22. The elongated flat outer shell 21 has an opening 212 at one end (lower end) and an air outlet 210 at the other end (upper end). One end of the air guide pipe 22 is connected to the air outlet 210, and the other end extends toward the opening 212 of the outer shell 21. In some embodiments, the air guide pipe 22 may be integrally formed with the outer shell 21, and its end is inserted into the atomizing body 100 to discharge the mist generated by the atomizing body 100 during operation. It is understood that the shape of the outer shell 21 is not limited to the shape shown in the figure; other shapes such as square tubes and cylinders may also be applicable.

[0055] In some embodiments, the end of the outer shell 21 with the vent 210 may be flattened to form a nozzle. The atomizing body 100 is inserted longitudinally into the housing 20 through the opening 212, and the opening 212 is sealed to achieve a seal of the liquid storage chamber 70. A slot 216 is also provided on the inner side of each end of the opening end of the outer shell 21 to engage with the atomizing body 100 inserted into the outer shell 21, preventing the atomizing body 100 from falling out of the housing 20.

[0056] For example Figures 3 to 7 As shown, in some embodiments, the outer casing 21 may include a first sidewall 211, a second sidewall 213, a third sidewall 215, and a fourth sidewall 217 connected sequentially in the circumferential direction. In some embodiments, the first sidewall 211 and the third sidewall 215 may be arc-shaped and located at both ends of the minor axis of the cross-section of the outer casing 21, respectively, and have a small curvature. In some embodiments, the second sidewall 213 and the fourth sidewall 217 may be arc-shaped and located at both ends of the major axis of the cross-section of the outer casing 21, respectively, and have a large curvature.

[0057] See also Figure 8In some embodiments, the atomizing body 100 may include a columnar atomizing base 10, an atomizing component 30 disposed on one side of the atomizing base 10, a fastener 40 for fixing the atomizing component 30 to the atomizing base 10, a first sealing member 50 disposed on the upper part of the atomizing base 10, and a second sealing member 60 disposed on the other side of the atomizing base 10. The atomizing base 10 forms the skeleton of the atomizing body 100 and forms an airflow channel and a conductive channel. The atomizing component 30 is used to heat and atomize the liquid in the liquid storage chamber 70 and release the mist into the atomizing base 10. The first sealing member 50 is used to seal the gap between the upper part of the atomizing base 10 and the air guide pipe 22, and also to form a ventilation channel together with the atomizing base 10. The second sealing member 60 is used to seal the clearance hole 1250 on the side wall of the atomizing base 10.

[0058] In some embodiments, the atomizing base 10 may include a base 11, a cylindrical atomizing chamber 12 longitudinally disposed on top of the base 11, and a cylindrical connecting chamber 13 disposed on top of the atomizing chamber 12. In some embodiments, the base 11 may be used to seal the opening 212 of the housing 20, provide an electrical connection to the atomizing assembly 30, and introduce ambient air into the atomizing chamber 12. In some embodiments, the atomizing chamber 12 may form an atomizing cavity 120, on which the atomizing assembly 30 may be mounted and connected in communication with the atomizing cavity 120. In some embodiments, the connecting chamber 13 may be used to connect the atomizing cavity 120 to the air duct 22 of the housing 20, to partition the liquid storage tank 70, and to ventilate the liquid storage tank 70.

[0059] See also Figure 9 In some embodiments, the base 11 may include a base body 111 with a generally elliptical cross-section, a sealing ring 112 fitted onto the base body 111, and a pair of electrodes 113 integrally formed in the base body 111. The base body 111 and the sealing ring 112 together are used to seal the opening 212 of the housing 20, and the pair of electrodes 113 are used to electrically connect the atomizing component 30 to the positive and negative terminals of the power supply device 2, respectively. In some embodiments, the base body 111 is integrally injection molded.

[0060] See also Figure 11 In some embodiments, electrode 113 may be integrally bent from an elastic conductive material such as a metal sheet. It may include a U-shaped first conductive end 1131 fixed in the base body 111 with its middle part exposed on the bottom surface of the base body 111, and a second conductive end 1132 connected to the first conductive end 1131, protruding from the top surface of the base body 111 and tilted to one side. The first conductive end 1131 is used for electrical connection with the power supply device 2, and the second conductive end 1132 is elastically pressed against the atomizing component 30.

[0061] For example Figure 9As shown, in some embodiments, the base 11 may further include an air intake channel 114 extending through the top and bottom of the base body 111, a flow guide structure 115 disposed on the top surface of the base body 111 and located near the air outlet of the air intake channel 114, and a pair of latching arms 116 respectively disposed at two opposite ends of the top surface of the base body 111. The air intake channel 114 is used to allow ambient air to enter the atomizing chamber 120, and the flow guide structure 115 is used to guide the airflow to the atomizing assembly 30. The pair of latching arms 116 are used to engage with the two slots 216 of the outer casing 21 respectively. In some embodiments, the extending direction of the air intake channel 114 may be parallel to the longitudinal axis X of the atomizer 1.

[0062] In some embodiments, the cross-section of the air intake channel 114 may be rectangular, thus forming a longitudinally elongated slit. In some embodiments, the air intake channel 114 may include a lower, longitudinally extending air intake section 1141, an upper, longitudinally extending air outlet section 1143, and a transition section 1142 connecting the air intake section 1141 and the air outlet section 1143. Preferably, the air intake section 1141, the transition section 1142, and the air outlet section 1143 are flush on two walls in the width direction and one wall in the thickness direction to facilitate demolding during integral injection molding.

[0063] In some embodiments, both the air inlet section 1141 and the air outlet section 1143 can be rectangular parallelepiped, while the transition section 1142 can be wedge-shaped. The thickness of the air inlet section 1141 is greater than the thickness of the air outlet section 1143, resulting in a larger cross-sectional area of ​​the air inlet section 1141 than that of the air outlet section 1143. This allows the inhaled gas to be accelerated as it flows out through the air outlet section 1143, thus better directing it towards the atomizing assembly 30.

[0064] In some embodiments, the air intake channel 114 is configured in the stepped shape described above, and preferably the length of the air outlet section 1143 is one-fifth to one-third of the total length of the air intake channel 114, which also facilitates the forming of the air intake channel 114. Because during the integral forming process of the base body 111, if the thickness of the entire air intake channel 114 is as thin as the air outlet section 1143, the mold used to form the air intake channel 114 will be both thin and long. During integral injection molding and other forming processes, the mold is prone to deformation or breakage under pressure, thus failing to form a qualified air intake channel 114. However, the mold for forming the air intake channel 114 has only a smaller thickness in the portion corresponding to the air outlet section 1143, and the length of this portion is one-fifth to one-third of the total mold length, while the other portions are relatively thick. This significantly improves the overall mold's resistance to deformation, ensuring both a narrow air passage and mold reliability.

[0065] In some embodiments, the airflow guiding structure 115 may include a guiding surface 1151 located directly above the air outlet of the air outlet section 1143, which may be a plane inclined toward the atomizing assembly 30. It is understood that the cross-section of the air intake channel 114 is not limited to a rectangle; it may also be a longitudinally elongated slit, such as a long racetrack shape or a long ellipse, or a cylindrical slit such as a circle or a square.

[0066] For example Figure 3 and Figure 4 As shown, the atomizing cavity 12 may be cylindrical in some embodiments and may be integrally formed longitudinally on the top surface of the base body 111. In some embodiments, the atomizing cavity 12 may include a first sidewall 121, a second sidewall 123, a third sidewall 125, and a fourth sidewall 127 sequentially connected in the circumferential direction, which together define a generally cuboid-shaped atomizing cavity 120. The first sidewall 121, the second sidewall 123, and the fourth sidewall 127 of the atomizing cavity 12 are respectively opposite to the first sidewall 211, the second sidewall 213, and the fourth sidewall 217 of the outer shell 21, and all form gaps, which are interconnected in some embodiments. In some embodiments, the first sidewall 121, the second sidewall 123, and the fourth sidewall 127 may all include a flat outer surface.

[0067] The outer wall surface of the third sidewall 125 of the atomizing chamber 12 can be tightly attached to the inner wall surface of the third sidewall 215 of the outer shell 21 of the housing 20, and a clearance hole 1250 extending along the thickness direction is provided thereon (e.g., Figure 10 (As shown). The clearance hole 1250 is used to facilitate the molding of the atomizing seat 10. The second seal 60 is sealed in the clearance hole 1250 to prevent liquid leakage into the atomizing chamber 120. In some embodiments, the outer wall surface of the third sidewall 125 may be arc-shaped to better fit against the inner wall surface of the third sidewall 215 of the housing 21.

[0068] like Figure 8 and Figure 9As shown, in some embodiments, the first sidewall 121 of the atomizing chamber 12 may include a receiving groove 1210 for accommodating the atomizing component 30 and an opening 1212 for communicating the receiving groove 1210 with the atomizing chamber 120. In some embodiments, the receiving groove 1210 may be formed by a recess in the outer surface of the first sidewall 121 in a direction away from the first sidewall 211 of the outer casing 21. In some embodiments, the opening 1212 may be formed in the middle of the bottom of the receiving groove 1210, making the bottom of the receiving groove 1210 annular. The shape and size of the opening 1212 may be adapted to the shape and size of the atomizing surface of the atomizing component 30, thereby allowing the atomizing surface of the atomizing component 30 to be fully exposed in the atomizing chamber 120. The second conductive end 1132 of the electrode 113 of the base 11 extends into the opening 1212 and elastically abuts against the atomizing component 30. In some embodiments, the outer surfaces of the second sidewall 123 and the fourth sidewall 127 may be respectively provided with locking platforms 122 for engaging with the fastener 40. In some embodiments, the outer surface of the first sidewall 121 may be a plane.

[0069] In some embodiments, the plane containing the bottom of the receiving groove 1210 may be parallel to the longitudinal axis X of the atomizer 1, so that the atomizing assembly 30 can be installed in the receiving groove 1210, and its atomizing surface is also parallel to the longitudinal axis X of the atomizer 1. It can be understood that the plane containing the bottom of the receiving groove 1210 is not limited to being parallel to the longitudinal axis X of the atomizer 1; it may also form a slight angle with the longitudinal axis X, and this angle is preferably less than 30 degrees.

[0070] For example Figure 8 As shown, in some embodiments, the connecting cavity 13 may include a first sidewall 131, a second sidewall 133, a third sidewall 135, and a fourth sidewall 137 sequentially connected in the circumferential direction. These sidewalls 131, 133, 135, and 137 together define a cylindrical cavity 130 for the first sealing member 50 to be fitted therein. In some embodiments, the connecting cavity 13 may be integrally formed longitudinally on the top of the atomizing cavity 12, and its third sidewall 135 and the third sidewall 125 of the atomizing cavity 12 are on the same vertical plane. The distance between the first sidewall 131 and the third sidewall 135 of the connecting cavity 13 is greater than the distance between the first sidewall 121 and the third sidewall 125 of the atomizing cavity 12.

[0071] See also Figure 3The outer surfaces of the first sidewall 131 and the third sidewall 135 abut against the inner surfaces of the first sidewall 211 and the third sidewall 215 of the outer shell 21, respectively, dividing the liquid storage chamber 70 into a first liquid storage section 71 located below the connecting cavity 13 and a second liquid storage section 72 located above the connecting cavity 13. The first liquid storage section 71 is formed by the gap between the atomizing cavity 12 and the first sidewall 211, the second sidewall 213 and the fourth sidewall 217 of the outer shell 21, and surrounds the atomizing cavity 12 in a C-shape.

[0072] See also Figure 4 The second sidewall 133 and the fourth sidewall 137 of the connecting cavity 13 are opposite to the second sidewall 213 and the fourth sidewall 217 of the outer shell 21, respectively, and form two gaps. These two gaps connect the first liquid storage part 71 and the second liquid storage part 72, respectively forming a first liquid discharge channel 73 and a second liquid discharge channel 74 from the second liquid storage part 72 into the first liquid storage part 71.

[0073] In some embodiments, the lower corners of the junction between the first sidewall 131 and the second sidewall 133 of the connecting cavity 13 and the lower corners of the junction between the first sidewall 131 and the fourth sidewall 137 are all rounded to allow the liquid to flow more smoothly from the second liquid storage section 72 into the first liquid storage section 71, and to reduce the adhesion and retention of air bubbles in the first liquid storage section 71 during the liquid discharge process, thereby preventing or reducing the dry burning problem caused by air bubbles adhering to the heating element 31.

[0074] In some embodiments, a step 132 may be provided at the connection between the connecting cavity 13 and the atomizing cavity 12. The top surface of the step forms a first air guide groove 1320 with capillary force that communicates with the atomizing cavity 120 and extends horizontally. In some embodiments, the third sidewall 135 of the connecting cavity 13 may include a longitudinally extending second air guide groove 1351 with capillary force formed on its inner surface. The lower end of the second air guide groove 1351 communicates with the first air guide groove 1320. In some embodiments, the third sidewall 135 may also include a longitudinally extending third air guide groove 1353 with capillary force formed on its outer surface and an air guide hole 1352 that penetrates the third sidewall 135 to communicate with the second air guide groove 1351. The upper end of the third air guide groove 1353 communicates with the second liquid storage part 72 of the liquid storage tank 70. The first air guide groove 1320, the second air guide groove 1351, the air guide hole 1352 and the third air guide groove 1353 together form the air exchange channel of the atomizer 1 to achieve gas-liquid balance in the liquid storage chamber 70.

[0075] In some embodiments, the atomizing base 10, consisting of a base body 111, an atomizing chamber 12, and a connecting chamber 13, can be integrally injection molded. In this way, the formation of the atomizing chamber 120 and the separation of the liquid storage portion of the liquid storage tank 70 can be achieved primarily with a single part (the atomizing base body), greatly reducing the number of components in the atomizing body 100, improving the assembly efficiency of the atomizing body 100, and reducing the overall manufacturing cost of the atomizing body 100. After the atomizing base body is integrally molded, the gaps between components are reduced, and the risk of leakage is also lowered.

[0076] For example Figure 9 As shown, in some embodiments, the first sealing element 50 may be made of a soft material such as silicone, and may include a cylindrical body 51 and a flange 53 formed on the upper side edge of the cylindrical body 51. The outer diameter of the cylindrical body 51 is adapted to the inner diameter of the cavity 130 of the connecting cavity 13 so that the cylindrical body 51 can be tightly fitted into the cavity 130 axially. The lower end face of the cylindrical body 51 abuts against the top surface of the step 132. The cylindrical body 51 includes a through central hole 510 for the air guide pipe 22 of the housing 20 to be inserted and connected to the atomizing chamber 120. In some embodiments, the first sealing element 60 is also made of a soft material such as silicone and is in the form of a block.

[0077] like Figure 12 As shown, in some embodiments, the atomizing component 30 may include a sheet-like heating element 31 and a square-shaped soft seal 32 attached to the periphery of the sheet-like heating element 31. In some embodiments, the sheet-like heating element 31 may be square-shaped and may include a sheet-like substrate 311 and a heating layer 312 formed on the bottom surface of the substrate 311. The substrate 311 may be glass or dense ceramic with a microporous array, or it may be sheet-like porous ceramic. In some embodiments, the seal 32 may be integrally injection molded with the heating element 31. In other embodiments, the seal 32 may be composed of two or more structures joined together.

[0078] For example Figure 9 and Figure 10As shown, in some embodiments, the latching component 40 can be integrally formed from a metal sheet, comprising a latching body 41 with an opening 410 and a first latching arm 42 and a second latching arm 43 respectively connected to two opposite sides of the latching body 41. The latching body 41 presses against the outside of the atomizing component 30, and the first latching arm 42 and the second latching arm 43 respectively latch onto the side wall of the atomizing chamber 12, thus securing the atomizing component 30 to the atomizing chamber 12. The liquid absorption surface of the atomizing component 13 is exposed to the liquid storage chamber 70 through the opening 410. The four edges of the latching body 41 correspond to the four edges of the sealing element 32 of the atomizing component 30, ensuring that the heating element 31 of the atomizing component 30 is evenly stressed around its perimeter, preventing excessive stress and breakage. The latching body 41 also functions as a reinforcing member for the heating element 31.

[0079] Figures 13 to 18 Atomizing base 10a is shown in some other embodiments of the present invention. This atomizing base 10a can be used as an alternative to the aforementioned atomizing base 10. In some embodiments, it may include a base 11a, a cylindrical atomizing cavity 12a longitudinally disposed on top of the base 11a, and a cylindrical connecting cavity 13 disposed on top of the atomizing cavity 12a. In some embodiments, the base 11a may be used to seal the opening 212 of the housing 20, provide an electrical connection to the atomizing assembly 30, and introduce ambient air into the atomizing cavity 12a. In some embodiments, the atomizing cavity 12a may be used to form an atomizing cavity 120a, on which the atomizing assembly 30 may be mounted and connected. In some embodiments, the connecting cavity 13a may be used to connect the atomizing cavity 120a to the air duct 22 of the housing 20, to partition the liquid storage tank 70, and to ventilate the liquid storage tank 70.

[0080] In some embodiments, the base 11a may include a base body 111a with a generally elliptical cross-section, comprising an annular first portion 1111a and a columnar second portion 1112a axially fitted into a central through-hole of the annular first portion 1111a. In some embodiments, both the first portion 1111a and the second portion 1112a may be integrally injection molded. Preferably, the second portion 1112a is made of a softer material so that it can be securely fitted into the first portion 1111a.

[0081] In some embodiments, the base 11a may further include a sealing ring 112a fitted onto a first portion 1111a of the base body 111a and a pair of electrodes 113a integrally formed in a second portion 1112a of the base body 111a. The base body 111a and the sealing ring 112a together are used to seal the opening 212 of the housing 20, and the pair of electrodes 113a are used to electrically connect the atomizing component 30 to the positive and negative poles of the power supply device 2, respectively.

[0082] See also Figure 19 In some embodiments, electrode 113a may be integrally bent from an elastic conductive material such as a metal sheet. It may include a first conductive end 1131a fixed in the base body 111a and partially exposed on the bottom surface of the second part 1112a of the base body 111a, and a second conductive end 1132a connected to the first conductive end 1131a and protruding from the top surface of the second part 1112a and tilted to one side. The first conductive end 1131a is used for electrical connection with the power supply device 2, and the second conductive end 1132a is elastically pressed against the atomizing component 30.

[0083] For example Figure 17 and Figure 18 As shown, in some embodiments, the base 11 may further include an air intake channel 114a extending vertically through the second portion 1112a of the base body 111a, a flow guide structure 115a disposed on the top surface of the second portion 1112a of the base body 111a and located near the air outlet of the air intake channel 114a, and a pair of latching arms 116a respectively disposed at opposite ends of the top surface of the first portion 1111a of the base body 111a. The air intake channel 114a is used to allow ambient air to enter the atomizing chamber 120a, and the flow guide structure 115a is used to guide the airflow to the atomizing assembly 30. The pair of latching arms 116a are used to engage with the two slots 216 of the outer casing 21 respectively.

[0084] In some embodiments, the cross-section of the air intake channel 114a may be rectangular, forming a long, narrow slit. It includes a lower air intake section 1141a, an upper air outlet section 1143a, and a transition section 1142a connecting the air intake section 1141a and the air outlet section 1143a. The cross-sectional area of ​​the air intake section 1141a is larger than that of the air outlet section 1143a, so that the inhaled gas is accelerated as it flows out through the air outlet section 1143a, and thus better directed towards the atomizing assembly 30. In some embodiments, the flow guiding structure 115a may include a flow guiding surface 1151a located directly above the air outlet of the air outlet section 1143a. This flow guiding surface 1151a may be a plane inclined towards the atomizing assembly 30. It is understood that the cross-section of the air intake channel 114 is not limited to a rectangle; it may also be a long, narrow slit in the shape of a long racetrack, a long, narrow ellipse, or a cylindrical slit such as a circle or a square.

[0085] In some embodiments, the angle between the guide surface 1151 and the longitudinal direction of the air outlet section 1143 is 90-160°, preferably 90-135°. In some embodiments, the slit width of the air outlet section 1143 is preferably 0.5-1.0 mm. In some embodiments, the plane containing the air outlet of the air outlet section 1143 is preferably 0.5-1.5 mm lower than the atomizing surface of the atomizing component 30 to minimize airflow loss. In some embodiments, the longitudinal direction of the air outlet section 1143 is parallel to the atomizing surface of the atomizing component 30.

[0086] Understandably, the aforementioned air outlet is designed as a slit and works in conjunction with the airflow guiding structure to help increase the airflow velocity and flow rate towards the atomizing surface of the atomizing component 30, thereby improving the efficiency of carrying away the atomized gas. In addition, the slit width of the air intake channel 114, which is widened at first and then narrowed, can improve suction resistance.

[0087] In some embodiments, the atomizing cavity 12a may be cylindrical and integrally formed longitudinally on the top surface of the first portion 1111a of the base body 111a. In some embodiments, the atomizing cavity 12a may include a first sidewall 121a, a second sidewall 123a, a third sidewall 125a, and a fourth sidewall 127a connected sequentially in the circumferential direction, these sidewalls together defining a generally cuboid-shaped atomizing cavity 120a. The first sidewall 121a, the second sidewall 123a, and the fourth sidewall 127a of the atomizing cavity 12 are respectively opposite to the first sidewall 211, the second sidewall 213, and the fourth sidewall 217 of the outer casing 21, and each has gaps that are interconnected. In some embodiments, the first sidewall 121a, the second sidewall 123a, and the fourth sidewall 127a may all include a flat outer surface. The outer wall surface of the third sidewall 125a can be closely attached to the inner wall surface of the third sidewall 215 of the outer shell 21 of the housing 20. In some embodiments, the outer wall surface of the third sidewall 125 can be arc-shaped to better fit the inner wall surface of the third sidewall 215 of the outer shell 21.

[0088] In some embodiments, the first sidewall 121a of the atomizing chamber 12a may include a receiving groove 1210a for accommodating the atomizing component 30 and an opening 1212a for connecting the receiving groove 1210a to the atomizing chamber 120a. In some embodiments, the receiving groove 1210a may be recessed from the outer surface of the first sidewall 121a toward the first sidewall 211a of the outer casing 21. In some embodiments, the opening 1212a may be formed in the middle of the bottom of the receiving groove 1210a, and its shape and size may be adapted to the shape and size of the atomizing surface of the atomizing component 30. The second conductive end 1132a of the electrode 113a extends into the opening 1212a and elastically abuts against the atomizing component 30. In some embodiments, the outer surfaces of the second sidewall 123a and the fourth sidewall 127a may be respectively provided with locking platforms 122a for engaging with the locking member 40. In some embodiments, the outer surface of the first sidewall 121 may be planar.

[0089] In some embodiments, the connecting cavity 13a may include a first sidewall 131a, a second sidewall 133a, a third sidewall 135a, and a fourth sidewall 137a sequentially connected in the circumferential direction. These sidewalls 131a, 133a, 135a, and 137a together define a cylindrical cavity 130a for the first sealing member 50 to be fitted therein. In some embodiments, the connecting cavity 13a may be integrally formed longitudinally on the top of the atomizing cavity 12a, and its third sidewall 135a and the third sidewall 125a of the atomizing cavity 12a are on the same vertical plane. The distance from the first sidewall 131a to the third sidewall 135a of the connecting cavity 13a is greater than the distance from the first sidewall 121a to the third sidewall 125a of the atomizing cavity 12a.

[0090] The outer surfaces of the first sidewall 131a and the third sidewall 135a abut against the inner surfaces of the first sidewall 211 and the second sidewall 213 of the outer shell 21, respectively, dividing the liquid storage chamber 70 into a first liquid storage section 71 located below the connecting cavity 13a and a second liquid storage section 72 located above the connecting cavity 13a. The first liquid storage section 71 is formed by the gap between the atomizing cavity 12 and the first sidewall 211, the second sidewall 213, and the fourth sidewall 217 of the outer shell 21, and surrounds the atomizing cavity 12 in a C-shape. The second sidewall 133a and the fourth sidewall 137a of the connecting cavity 13a are opposite to the second sidewall 213 and the fourth sidewall 217 of the outer shell 21, respectively, and form two gaps. These two gaps connect the first liquid storage section 71 and the second liquid storage section 72, respectively forming a first liquid discharge channel 73 and a second liquid discharge channel 74 from the second liquid storage section 72 into the first liquid storage section 71.

[0091] In some embodiments, a step 132a may be provided at the connection between the connecting cavity 13a and the atomizing cavity 12a. The top surface of the step forms a first air guide groove 1320a with capillary force that communicates with the atomizing cavity 120a and extends horizontally. In some embodiments, the third sidewall 135a of the connecting cavity 13a may include a longitudinally extending second air guide groove 1351a with capillary force formed on its inner surface. The lower end of the second air guide groove 1351a communicates with the first air guide groove 1320a. In some embodiments, the third sidewall 135a may also include a longitudinally extending third air guide groove 1353a with capillary force formed on its outer surface and an air guide hole 1352a that penetrates the third sidewall 135a to communicate with the second air guide groove 1351a. The upper end of the third air guide groove 1353a communicates with the second liquid storage part 72 of the liquid storage tank 70. The first air guide groove 1320a, the second air guide groove 1351a, the air guide hole 1352a and the third air guide groove 1353a together form the air exchange channel of the atomizer 1 to achieve gas-liquid balance in the liquid storage chamber 70.
