[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411435056.X, filed on October 14, 2024, entitled "Atomizing Component and Electronic Atomizing Device", and Chinese Patent Application No. 202411433473.0, filed on October 14, 2024, entitled "Electronic Atomizing Device, Power Supply Body for Electronic Atomizing Device and Atomizing Body", the contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and in particular to an atomization component and an electronic atomization device. Background Technology

[0004] Electronic atomizing devices are electronic products that generate aerosols by atomizing a liquid matrix for users to inhale. They generally consist of two parts: an atomizer and a power supply component. The atomizer stores the liquid matrix and contains an atomizing core for atomizing the liquid matrix, while the power supply component includes a battery and a circuit board.

[0005] Existing electronic atomization devices, limited by various factors such as cost and regulations, generally have a relatively small amount of liquid matrix stored inside the atomizer. When the liquid matrix is ​​depleted, it can be used again by refilling the liquid, replacing the atomizer, or simply discarding it. These methods, on the one hand, cause inconvenience to users and reduce their user experience, and on the other hand, increase their operating costs.

[0021] In one example, at least one longitudinally extending capillary groove is arranged on the inner surface of the first liquid transfer channel and / or the second liquid transfer channel.

Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0092] As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0093] As used here, when an element is described as being "fixed to" another element, it can be directly on the other element or there can be one or more intervening elements therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element or there can be one or more intervening elements therebetween.

[0094] As used here, the terms “up,” “down,” “left,” “right,” “inner,” “outer,” and similar expressions are used for illustrative purposes only.

[0095] As used herein, the terms “first,” “second,” etc., are used to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, particular order, or primary or secondary relationship of the indicated technical features.

[0096] As used here, the terms 'upstream' and 'downstream' describe the relative positions of components or parts of components in an electronic atomizing device in terms of the direction of the suction airflow.

[0097] As shown in Figures 1-4, an embodiment of this application provides an electronic atomizing device 10, including a mouthpiece assembly 100, a first atomizing assembly 200, a second atomizing assembly 300, and a power supply assembly 400. The electronic atomizing device 10 is generally cuboid in shape. In the figures, the X direction represents the width direction of the electronic atomizing device 10, the Y direction represents the thickness direction of the electronic atomizing device 10, and the Z direction represents the length direction of the electronic atomizing device 10. The dimension in the length direction is larger than the dimension in the width direction, and the dimension in the width direction is larger than the dimension in the thickness direction.

[0098] The mouthpiece assembly 100 is detachably connected to the power supply assembly 400. After the mouthpiece assembly 100 and the power supply assembly 400 are connected, they together define the housing of the electronic atomizing device 10.

[0099] As shown in Figures 5 and 6, the nozzle assembly 100 includes a nozzle component 101, a cover 102, a sealing component 103, and a fixing connector 104.

[0100] The mouthpiece 101 includes a cover plate 101a and a mouthpiece 101b protruding from the cover plate 101a. The cover plate 101a covers the cover body 102 and defines the top wall of the electronic atomizing device 10. A protrusion 101a1 is provided on the surface of the cover plate 101a facing the cover body 102. The protrusion 101a1 is hollow inside and has an opening at its lower end. An indicator 101a2 is provided on the surface of the cover plate 101a facing away from the cover body 102. A rotating arrow (not shown in the attached figure) is printed on the surface of the indicator 101a2. The mouthpiece 101b can be held by a user, and an air outlet channel 101b1 is provided inside the mouthpiece 101b.

[0101] The cover 102 is generally cylindrical, with the upper end of the cover 102 closed and the lower end of the cover 102 open. The cover 102 has a cavity that communicates with the lower end opening of the cover 102.

[0102] The upper end face of the cover 102 is provided with an air passage 102a, an air passage 102b, and a connecting hole 102c. The air passage 102a, air passage 102b, and connecting hole 102c are arranged along the width direction of the electronic atomizing device 10, and the connecting hole 102c is arranged between the air passage 102a and the air passage 102b. The air passage 102a, air passage 102b, and connecting hole 102c are all in communication with the cavity inside the cover 102. The upper end of the connecting hole 102c protrudes from the upper end face of the cover 102, and the lower end of the connecting hole 102c extends into the cavity inside the cover 102, thereby forming a protrusion (second protrusion) extending into the cavity inside the cover 102.

[0103] The sealing element 103 is generally plate-shaped and can be made of silicone. The sealing element 103 is disposed on the upper end face of the cover 102. The sealing element 103 has through holes corresponding to vent holes 102a, 102b, and 102c. The through holes on the sealing element 103 corresponding to vent holes 102a or 102b can be embedded in vent holes 102a or 102b; the through holes on the sealing element 103 corresponding to 102c can be fitted onto 102c.

[0104] After assembly, the protrusion 101a1 is inserted into the connecting hole 102c, and the fixing connector 104, such as a screw, can be fixed in the protrusion 101a1. The air outlet channel 101b1 can selectively communicate with one of the air passages 102a or 102b. The protrusion 101a1 and the fixing connector 104 can move up and down together in the connecting hole 102c. Thus, during use, the user can pinch the nozzle 101b and rotate the nozzle 101 by 180°, so that the air outlet channel 101b1 can selectively communicate with the other of the air passages 102a or 102b. The fixing connector 104 includes an elastic element, such as a spring, which is sleeved on the protrusion 101a1. As can also be seen from the figure, one end of the air outlet channel 101b1 can abut against the sealing element 103, thereby forming a good airtightness.

[0105] As shown in Figures 7 and 8, the power supply assembly 400 includes a third housing 401, a battery cell 402, a circuit board 403, a seal 404, a cover 405, and a display component 406.

[0106] The third housing 401 is generally rectangular in shape, with an opening at the top (the third opening) and a closed bottom. The third housing 401 has a cavity that communicates with the opening at the top.

[0107] The third housing 401 is provided with a partition 401b, which divides the cavity inside the third housing 401 into a first receiving cavity 401c, a second receiving cavity 401d, and a third receiving cavity 401e. The first receiving cavity 401c, the second receiving cavity 401d, and the third receiving cavity 401e are all connected to the upper opening of the third housing 401. The first receiving cavity 401c, the second receiving cavity 401d, and the third receiving cavity 401e are arranged along the width direction of the electronic atomizing device 10. The third receiving cavity 401e is arranged between the first receiving cavity 401c and the second receiving cavity 401d. The third receiving cavity 401e is separated from the first receiving cavity 401c by a partition 401b. The third receiving cavity 401e is also separated from the second receiving cavity 401d by a partition 401b. The partition 401b and the inner wall of the third housing 401 enclose the opening (second opening) of the third receiving cavity 401e. The opening of the third receiving cavity 401e is located inside the third housing 401.

[0108] The first atomizing component 200 is at least partially removably installed in the first receiving cavity 401c, and the second atomizing component 300 is at least partially removably installed in the second receiving cavity 401d.

[0109] Steps 401f are also provided on two side walls that are arranged opposite each other along the width direction of the electronic atomizing device 10 inside the third housing 401. When the first atomizing component 200 or the second atomizing component 300 is installed into the receiving cavity, the edge of the first atomizing component 200 or the second atomizing component 300 can abut against the step 401f.

[0110] The bottom wall of the third housing 401 is provided with an air inlet 401g (second air inlet), which is connected to the third receiving cavity 401e. The two side walls inside the third housing 401, which are arranged opposite each other along the thickness direction of the electronic atomizing device 10, are also provided with a snap-fit ​​groove 401h (first snap-fit ​​groove).

[0111] Battery cell 402 is disposed in the third receiving cavity 401e. Battery cell 402 is used to provide power. Battery cell 402 can be a primary battery cell or a secondary battery cell.

[0112] Please refer to Figure 9 for understanding. Circuit board 403 is used to control the overall operation of the electronic atomizing device. Circuit board 403 is electrically connected to battery cell 402. Circuit board 403 is disposed at the opening of the third receiving cavity 401e and closes the opening of the third receiving cavity 401e, thereby making the third receiving cavity 401e a closed chamber. Specifically, circuit board 403 is placed on partition plate 401b and blocks the opening of the third receiving cavity 401e. Thus, circuit board 403 and the third receiving cavity 401e together define a spacer portion E, with circuit board 403 located at the proximal end of spacer portion E. On the proximal surface of spacer portion E adjacent to the opening end of the first receiving cavity 401c or the opening end of the second receiving cavity 401d, a second electrode assembly 4031 and a third electrode assembly 4034 spaced apart from each other are disposed.

[0114] The second electrode assembly 4031 and the third electrode assembly 4034 are spaced apart on the circuit board 403 and both protrude from the first mounting surface of the circuit board 403 away from the third receiving cavity 401e. Specifically, one end of the second electrode assembly 4031 can be connected to the circuit board 403, and the other end of the second electrode assembly 4031 extends toward the nozzle assembly 100 or toward a direction away from the third receiving cavity 401e; one end of the third electrode assembly 4034 can be connected to the circuit board 403, and the other end of the third electrode assembly 4034 extends toward the nozzle assembly 100 or toward a direction away from the third receiving cavity 401e. It is understood that the second electrode assembly 4031 includes a positive electrode 4031a and a negative electrode 4031b spaced apart, and the third electrode assembly 4034 includes a positive electrode 4034a and a negative electrode 4034b spaced apart. The second electrode assembly 4031 or the third electrode assembly 4034 preferably uses flexible electrodes, such as columnar POGO PINs.

[0115] Air vents 4032 and 4035 are spaced apart and both penetrate the circuit board 403. The first airflow sensor 4033 and the second airflow sensor 4036 are spaced apart. The first airflow sensor 4033 and the second airflow sensor 4036 can be common microphones or MEMS (microelectromechanical systems) sensors.

[0116] The connection hole 4037 is located near the edge of the circuit board 403 and passes through the circuit board 403. The number of connection holes 4037 is not limited.

[0117] Please refer to Figures 10-11 for understanding. The seal 404 (second seal) is generally plate-shaped and can be made of silicone. The seal 404 is mounted on the circuit board 403.

The lower surface of the seal 404 facing the circuit board 403 has a first sealing cavity 4041 and a second sealing cavity 4042 spaced apart. The first airflow sensor 4033 is housed in the first sealing cavity 4031, and the second airflow sensor 4036 is housed in the second sealing cavity 4042. The upper surface of the seal 404 opposite to the circuit board 403 has a first airflow cavity 4043 and a second airflow cavity 4044 spaced apart. The seal 404 also has vent holes 4045 and 4046, a sensing channel 4047, and a sensing channel 4048 penetrating the upper and lower surfaces. Vent hole 4045 is aligned and communicates with vent hole 4032. One end of vent hole 4045 is located on the lower surface of seal 404 and spaced apart from the first sealing cavity 4041. The other end of vent hole 4045 is located on the upper surface of seal 404 and is disposed in the first airflow cavity 4043. Vent hole 4046 is aligned and communicates with vent hole 4035. One end of vent hole 4046 is located on the lower surface of seal 404 and spaced apart from the second sealing cavity 4042. The other end of vent hole 4046 is located on the upper surface of seal 404 and is disposed in the second airflow cavity 4043. In section 44, one end of sensing channel 4047 is disposed in the first sealing cavity 4041, and the other end of sensing channel 4047 is disposed in the first airflow cavity 4043. The first airflow sensor 4033 can sense the airflow changes in the first airflow cavity 4043 through sensing channel 4047. One end of sensing channel 4048 is disposed in the second sealing cavity 4042, and the other end of sensing channel 4048 is disposed in the second airflow cavity 4044. The second airflow sensor 4036 can sense the airflow changes in the second airflow cavity 4044 through sensing channel 4048. The sealing member 404 is also provided with sealing holes 4049 penetrating the upper and lower surfaces. The number of sealing holes 4049 is the same as the number of the second electrode assembly 4031 and the third electrode assembly 4034. Each electrode can extend toward the nozzle assembly 100 through the corresponding sealing hole 4049.

[0118] Please refer to Figure 12 for understanding. The cover 405 is also disposed on the first mounting surface of the circuit board 403 facing away from the third receiving cavity 401e. The cover 405 covers the sealing member 404. The cover 405 has a protrusion 4051 (first protrusion) extending toward the circuit board 403. The protrusion 4051 and the connecting hole 4037 form a second connecting mechanism, thereby allowing the cover 405 to better hold the circuit board 403 on the partition 401b. The cover 405 also has two snap fasteners 4052 (second snap fasteners) disposed on two side walls opposite each other along the thickness direction of the electronic atomizing device 10. The snap fasteners 4052 and the snap groove 401h form a third connecting mechanism, thereby allowing the cover 405 to be better held in the third housing 401. The cover 405 is also provided with a through hole 4053 corresponding to the first airflow chamber 4043 and a through hole 4054 corresponding to the second airflow chamber 4044, thereby exposing the first airflow chamber 4043 and the second airflow chamber 4044. The cover 405 is also provided with a through hole 4055 corresponding to the sealing hole 4049. The number of through holes 4055 is the same as the number of sealing holes 4049, or the same as the number of the second electrode assembly 4031 and the third electrode assembly 4034. The other end of each electrode can extend to the outside of the cover 405 or be exposed on the outer surface of the cover 405 through the corresponding through hole 4055.

[0119] The display component 406 is installed together with the battery cell 402 into the third receiving cavity 401e. The display component 406 is used to display information of the electronic atomizing device 10, such as the charge of the battery cell 402, the remaining amount of liquid matrix, etc.

[0120] Please refer to Figure 8 for further understanding. Air outside the electronic atomizing device 10 can flow into the third receiving cavity 401e through the air inlet 401g, and then flow into the air passage 4032 (air passage 4035) through the gap between the battery cell 402 and the partition 401b. Then, it flows into the first airflow cavity 4043 (second airflow cavity 4044) through the air passage 4045 (air passage 4046). For details, please refer to the dashed arrows in Figure 8.

[0121] In the examples shown in Figures 1-4, the first atomizing component 200 and the second atomizing component 300 have completely identical structures. This arrangement facilitates mass production of the atomizing components, simplifies the structural design of the power supply component 400, and facilitates the assembly of the atomizing components and the power supply component 400. It is understandable that in other examples, it is also feasible to differentiate the first atomizing component 200 and the second atomizing component 300 through structural design. The specific structure of the first atomizing component 200 is described below:

[0122] As shown in Figures 13-16, the first atomizing component 200 includes an atomizing part 201 and a replenishing part 203 for replenishing the atomizing part 201 with a liquid matrix.

[0123] The atomizing part 201 includes a first housing 2011 (first housing). The first housing 2011 is composed of a main housing 20111 and a bottom cover 20112. The main housing 20111 and the bottom cover 20112 can be detachably connected by a connecting mechanism, such as a snap-fit ​​connection. The main housing 20111 defines the upper surface of the first housing 2011, and the bottom cover 20112 defines the lower surface of the first housing 2011. The upper surface of the first housing 2011 is provided with an air outlet 20111a (first air outlet), and the lower surface of the first housing 2011 is provided with an air inlet 20112a (first air inlet). The first housing 2011 has an airflow channel extending from the air inlet 20112a to the air outlet 20111a (refer to the dashed arrow in Figure 16). The main housing 20111 is also provided with a notch 20111b.

[0124] As shown in Figure 18, a liquid storage cavity 2012 (first liquid storage cavity) is formed within the first housing 2011 for storing a first liquid matrix. The first liquid matrix can be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or it can be a liquid containing non-tobacco substances. For example, the first liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. Flavorings may include ingredients capable of providing the user with a variety of fragrances or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Additionally, the first liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0125] In a preferred embodiment, the liquid storage chamber 2012 is provided with a liquid storage medium 2013. The liquid storage medium 2013 is made of, for example, a fibrous material or a porous material. The liquid storage medium 2013 can adsorb and retain the liquid matrix. When the liquid storage medium 2013 reaches saturation after liquid injection, the content of the liquid matrix in the liquid storage medium 2013 is between 0.1 ml and 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml, etc.

[0126] Referring to Figures 17 and 18, the first housing 2011 also includes a seal 2014 and a seal 2015. The seal 2014 or seal 2015 may be made of silicone. The seal 2014 is positioned above the liquid storage medium 2013, and the seal 2015 is positioned below the liquid storage medium 2013. A portion of the space between the seal 2014 or seal 2015 and the liquid storage medium 2013 defines an air portion. The seals 2014 and 2015 can seal the liquid storage chamber 2012. The seal 2014 has a through hole 2014a communicating with the air outlet 20111a, and the seal 2015 has a through hole 2015a communicating with the air inlet 20112a. A liquid-absorbing medium 2016, such as absorbent cotton, is also provided between the seal 2014 and the air outlet 20111a. The liquid-absorbing medium 2016 can be contained in the receiving cavity 2014b of the seal 2014.

[0127] The first housing 2011 also includes a connecting pipe 2017. The upper end of the connecting pipe 2017 passes through the liquid storage cavity 2012 and connects to the sealing element 2014, while the lower end of the connecting pipe 2017 connects to the sealing element 2015. The connecting pipe 2017 is preferably made of a thin, rigid material, such as glass fiber or stainless steel. The liquid storage medium 2013 is fitted onto the connecting pipe 2017. Preferably, the inner diameter of the liquid storage medium 2013 is slightly smaller than the outer diameter of the connecting pipe 2017, so that the liquid storage medium 2013 is tightly fitted onto the connecting pipe 2017.

[0128] The first housing 2011 also includes an atomizing core 2018. The atomizing core 2018 includes a capillary liquid guiding element 2018a and a heating element 2018b. The capillary liquid guiding element 2018a can draw in the liquid matrix in the liquid storage medium 2013 and transfer the liquid matrix to the heating element 2018b. The heating element 2018b can be heated by an electric current supply and transfers heat to the liquid matrix in contact with the heating element 2018b to heat the liquid matrix, thereby generating an aerosol.

[0129] The capillary fluid guiding element 2018a is generally tubular in structure. It is understood that in other examples, it can also be a plate-like structure or other regular or irregular shapes. The capillary fluid guiding element 2018a can be made of flexible fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the capillary fluid guiding element 2018a can also be a rigid porous body, such as porous ceramics or porous glass. The outer surface of the capillary fluid guiding element 2018a has radially outward protrusions.

[0130] The heating element 2018b is disposed near the inner surface of the capillary liquid guide 2018a, and can abut against the inner surface of the capillary liquid guide 2018a, or be partially or completely embedded in the capillary liquid guide 2018a. The heating element 2018b can be a resistance heating mesh, a resistance heating coil, etc. The heating element 2018b can be made of a material with suitable temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 2018b can be wound from a sheet or mesh substrate, and the wound heating element 2018b is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length direction of the first atomizing assembly 200. Leads are welded or arranged at both ends of the heating element 2018b, and the leads can pass through the seal 2014 and be arranged outside the seal 2014, for example, on the surface of the seal 2014 facing the bottom cover 20112.

[0131] The atomizing core 2018 is disposed within the connecting tube 2017. Preferably, the atomizing core 2018 is coaxially disposed with the connecting tube 2017. The side wall of the connecting tube 2017 also has a liquid guide port, on which the liquid storage medium 2013 covers. A portion of the capillary liquid guide element 2018a is exposed in the liquid storage chamber 2012 through the liquid guide port, thereby allowing this portion of the capillary liquid guide element 2018a to be disposed close to or in contact with the liquid storage medium 2013. Consequently, the liquid matrix in the liquid storage chamber 2012 flows into the atomizing core 2018 through the liquid guide port, is absorbed by the capillary liquid guide element 2018a, and is atomized by the heating element 2018b to generate an inhalable aerosol.

[0132] A notch is also provided on the side wall of the connecting pipe 2017, extending from the lower end of the connecting pipe 2017 toward the upper end. The protruding portion of the capillary liquid guiding element 2018a extends into the notch, thereby exposing it in the liquid storage chamber 2012. After assembly, the liquid storage medium 2013 remains in contact with the protruding portion, thereby facilitating the capillary liquid guiding element 2018a to absorb the liquid matrix.

[0133] The atomizing section 201 includes a first electrode assembly 2019, which includes a positive electrode 2019a and a negative electrode 2019b spaced apart. The first electrode assembly 2019 preferably employs a flexible electrode, such as a columnar POGO PIN. One end of the first electrode assembly 2019 is exposed on the lower surface of the first housing 2011, and the other end passes through the bottom cover 20112 to maintain contact with the lead wire of the heating element 2018b, thereby forming an electrical connection.

[0134] The lower surface of the first housing 2011 is also provided with an opening 20112b (first opening), and the first housing 2011 also has a boss 20112c extending from the bottom cover 20112 toward the liquid storage cavity 2012. The boss 20112c is hollow inside and communicates with the opening 20112b.

[0135] The first housing 2011 also includes a liquid inlet pipe 2020. The upper end of the liquid inlet pipe 2020 is positioned near the seal 2014, and the lower end of the liquid inlet pipe 2020 is fitted onto the boss 20112c. The liquid inlet pipe 2020 and the boss 20112c together define a liquid inlet channel communicating with the opening 20112b. The side wall of the liquid inlet pipe 2020 is provided with a liquid guide port 2020a communicating with the liquid storage chamber 2012.

[0136] A capillary liquid guide 2021 is provided in the liquid inlet channel. The capillary liquid guide 2021 and the atomizing core 2018 are arranged at intervals along a direction parallel to the lower surface of the first housing 2011 in the first atomizing assembly 200. The cross-section of the capillary liquid guide 2021 gradually decreases from its upper end to its lower end. The upper end of the capillary liquid guide 2021 is located close to the seal 2014, and the lower end of the capillary liquid guide 2021 extends toward the opening 20112b. Through the structural layout of the capillary liquid guide 2021 extending from top to bottom to the second liquid storage chamber 2032, and in accordance with the user's posture, the liquid matrix in the second liquid storage chamber 2032 can overcome gravity and be conducted longitudinally from bottom to top, and then laterally to the first liquid storage chamber 2031. This effectively controls the velocity of the liquid matrix and avoids the risk of leakage from the airflow inlet due to oversaturation of the liquid matrix in the first liquid storage chamber 2031.

[0137] In a preferred embodiment, the upper end of the capillary liquid guiding element 2021 has a flange that abuts against the inner wall of the liquid inlet pipe 2020. The remaining portion of the capillary liquid guiding element 2021 forms a gap with the liquid inlet pipe 2020. During liquid conduction, this gap helps to adsorb and retain a small amount of liquid matrix, maintaining a continuous liquid supply. This allows for liquid replenishment when the capillary liquid guiding element in the first liquid storage chamber 2012 is low, preventing liquid loss in the atomizing core 2018. The material of the capillary liquid guiding element 2021 can be referenced from the portion described for the capillary liquid guiding element 2018a.

[0138] The lower surface of the first housing 2011 is also provided with a snap-fit ​​hole 20112d.

[0139] The fluid replenishment section 203 includes a second housing 2031 (second housing) independent of the first housing 2011. The second housing 2031 consists of a main housing 20311 and a top cover 20312. The main housing 20311 and the top cover 20312 can be detachably connected by a connecting mechanism, such as a snap-fit ​​connection.

[0140] A liquid storage cavity 2032 (second liquid storage cavity) is formed within the second housing 2031 for storing the second liquid matrix. Similar to the first liquid matrix, the second liquid matrix can be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or it can be a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, various fruit flavoring components, etc. Flavorings may include ingredients capable of providing the user with a variety of aromas or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Additionally, the second liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0141] It should be noted that the characteristics of the second liquid matrix and the first liquid matrix can be different or the same. For example, the composition of the second liquid matrix and the first liquid matrix may be different, or the concentration of the second liquid matrix and the first liquid matrix may be different. In some examples, the second liquid matrix and the first liquid matrix are liquid matrices of the same composition or type, and the second liquid matrix in the second liquid storage chamber 2032 serves as a liquid replenishment source for the first liquid storage chamber 2012.

[0142] The volume of the liquid storage chamber 2032 is larger than that of the liquid storage chamber 2012. Generally, the capacity of the second liquid matrix stored in the liquid storage chamber 2032 is between 2ml and 10ml, such as 4ml, 5ml, 6ml, 8ml, etc.

[0143] A sealing element 2033 is provided inside the second housing 2031. The sealing element 2033 is made of silicone. The sealing element 2033 is located between the main housing 20311 and the upper cover 20312, thereby sealing the liquid storage chamber 2032.

[0144] The upper surface of the second housing 2031 has a protruding connecting portion 20312a, and the connecting portion 20312a is provided with a liquid outlet 20312b communicating with the liquid storage chamber 2032. A sealing element 2034 is fitted onto the connecting portion 20312a.

[0145] The upper surface of the second housing 2031 is also provided with a snap fastener 20312c (first snap fastener). The snap fastener 20312c and the snap hole 20112d form a first connecting mechanism, thereby connecting the second housing 2031 to the first housing 2011. The second housing 2031 and the first housing 2011 can be a non-detachable connection or a detachable connection.

[0146] When the second housing 2031 is connected to the first housing 2011, the connecting part 20312a extends into the liquid inlet channel through the opening 20112b, and the lower end of the capillary liquid guide 2021 is inserted into the second housing 2031 through the liquid outlet 20312b. The sealing member 2033 is located between the boss 20112c and the connecting part 20312a. In this way, the second liquid matrix stored in the liquid storage chamber 2032 can flow through the liquid outlet 20312b to the liquid inlet channel, and then to the liquid storage chamber 2012, thereby replenishing the liquid storage chamber 2012. The sealing member 2033 prevents leakage of the liquid matrix in the liquid inlet channel. The capillary liquid guide 2021 effectively guides the second liquid matrix stored in the liquid storage chamber 2032 to the liquid storage chamber 2012. It is understandable that the connecting part 20312a does not extend into the liquid inlet channel, and the liquid outlet 20312b is aligned and connected with the opening 20112b.

[0147] When the second housing 2031 is connected to the first housing 2011, neither the air inlet 20112a nor the first electrode assembly 2019 is obstructed by the second housing 2031; that is, the second housing 2031 avoids the air inlet 20112a and the first electrode assembly 2019. The second housing 2031 is connected to the lower surface (first outer surface) of the first housing 2011, or, the second housing 2031 is connected to a portion of the lower surface of the first housing 2011; the air inlet 20112a is disposed on the first portion G of the lower surface of the first housing 2011, and one end of the first electrode assembly 2019 is also exposed on the first portion G of the lower surface of the first housing 2011. The second housing 2031 obstructs the second portion F of the lower surface of the first housing 2011 and avoids the first portion G of the lower surface of the first housing 2011, thereby exposing the air inlet 20112a and the first electrode assembly 2019 to the first portion G of the lower surface of the first housing 2011.

[0148] Understandably, before the second housing 2031 is connected to the first housing 2011, the opening 20112b, the liquid outlet 20312b, and the air outlet 20111a can all be sealed with seals to prevent leakage of the liquid matrix and facilitate product transportation. The seals can be made of silicone. After receiving the atomizing section 201 and the liquid replenishment section 203, the user can remove the seals and assemble the product themselves.

[0149] It should be noted that, based on the specific structure of the first atomizing component 200 described above, those skilled in the art can understand the second atomizing component 300 with the same structural design. It is understood that the liquid matrix in the first atomizing component 200 and the liquid matrix in the second atomizing component 300 may be different or the same.

[0150] When the first atomizing component 200 is installed into the first receiving cavity 401c, the second housing 2031 of the first atomizing component 200 is completely housed within the third housing 401, while the first housing 2011 of the first atomizing component 200 is at least partially exposed outside the third housing 401. The exposed portion of the first housing 2011 allows the user to easily grasp and remove the first atomizing component 200 from the first receiving cavity 401c. To facilitate the user's viewing of the remaining liquid matrix in the liquid storage cavity 2032, a viewing window is provided on the portion of the third housing 401 corresponding to the first receiving cavity 401c. The viewing window can be formed of a transparent material on the third housing 401 or it can be an opening on the third housing 401. It is understood that the same characteristics exist when the second atomizing component 300 is installed into the second receiving cavity 401d, and will not be elaborated upon here.

[0151] In a preferred embodiment, when the first atomizing component 200 is installed into the first receiving cavity 401c, the second housing 2031 of the first atomizing component 200 is at least partially located within the first receiving cavity 401c, while the first housing 2011 of the first atomizing component 200 can be partially housed between the spacer E and the upper opening of the third housing 401, with a portion of the first housing 2011 exposed outside the third housing 401. The same characteristics exist when the second atomizing component 300 is installed into the second receiving cavity 401d, and will not be elaborated further here.

[0152] When the first atomizing component 200 is installed into the first receiving cavity 401c, the first electrode component 2019 and the third electrode component 4034 of the first atomizing component 200 maintain contact in a one-to-one correspondence, thereby forming an electrical connection. When the second atomizing component 300 is installed into the second receiving cavity 401d, the electrode components of the second atomizing component 300 and the second electrode component 4031 maintain contact in a one-to-one correspondence, thereby forming an electrical connection.

[0153] When the first atomizing component 200 is installed into the first receiving cavity 401c and the second atomizing component 300 is installed into the second receiving cavity 401d, the first portion of the first outer surface of the first housing 2011 of the first atomizing component 200 and the first portion of the first outer surface of the housing of the atomizing portion of the second atomizing component 300 both abut against the cover 405, that is, against the spacer E. Since the liquid replenishment portions of the first atomizing component 200 and the second atomizing component 300 and the first electrode assembly are located on the same side surface, that is, the first outer surface, it is beneficial to save internal space of the power supply component and reduce the volume of the entire electronic atomizing device. Furthermore, during installation, the replenishment portions of the first atomizing component 200 and the second atomizing component 300 are correspondingly housed in the first receiving cavity 401c and the second receiving cavity 401d, respectively. The first portion of the first outer surface is connected to the spacer portion E. The proximal surface of the third electrode assembly in the spacer portion E is significantly higher than the bottom of the first receiving cavity 401c and the second receiving cavity 401d. Therefore, it can effectively prevent the liquid matrix in the atomizing portions of the first atomizing component 200 and the second atomizing component 300 from leaking onto the circuit board on the spacer portion E. Thus, the first portion G of the lower surface of the first housing 2011 in the first atomizing component 200 can block the second airflow chamber 4044 to form a closed chamber, thereby making the air inlet 20112a of the first atomizing component 200 connected to the second airflow chamber 4044. The airflow in the second airflow chamber 4044 can flow into the first atomizing component 200 through the air inlet 20112a, mix with the aerosol generated by the heating element 2018b, and then flow out from the air outlet 20111a of the first atomizing component 200. Correspondingly, the first part of the lower surface of the housing of the atomizing part in the second atomizing component 300 can block the first airflow chamber 4043 to form a closed chamber, thereby making the air inlet of the second atomizing component 300 connected to the first airflow chamber 4043. The airflow in the first airflow chamber 4043 can flow into the second atomizing component 300 through the air inlet of the second atomizing component 300, mix with the aerosol generated by the heating element in the second atomizing component 300, and then flow out from the air outlet of the second atomizing component 300.

[0154] When the nozzle assembly 100 is connected to the power supply assembly 400, at least a portion of the first housing 2011 exposed outside the third housing 401 and at least a portion of the housing of the second atomizing assembly 300 exposed outside the third housing 401 are both housed in the cavity within the cover 102.

[0155] When the first atomizing component 200 is installed into the first receiving cavity 401c and the second atomizing component 300 is installed into the second receiving cavity 401d, the notch 20111b of the first atomizing component 200 and the notch 20111b of the second atomizing component 300 surround each other to form a snap-fit ​​groove A (second snap-fit ​​groove). When the nozzle assembly 100 is connected to the power assembly 400, the protrusion formed by the lower end of the connecting hole 102c extending into the cavity inside the cover 102 can snap into the snap-fit ​​groove A, thereby effectively holding the first atomizing component 200 and the second atomizing component 300 in place.

[0156] When the mouthpiece assembly 100 is connected to the power supply assembly 400, the air outlet 20111a of the first atomizing assembly 200 is aligned and connected with the air passage 102a, and the air outlet of the second atomizing assembly 300 is aligned and connected with the air passage 102b, so that the aerosol generated by the first atomizing assembly 200 or the second atomizing assembly 300 can be inhaled by the user through the air outlet channel 101b1.

[0157] In some embodiments, please refer to Figures 20 to 32, the atomizing component of this application may also have a dual-channel structure.

[0158] Specifically, referring to Figures 20 and 22, the atomizing assembly 200 / 300 includes an atomizer 31 and a liquid reservoir 32 arranged sequentially along the longitudinal direction. The atomizer 31 stores the liquid matrix and atomizes it to generate an aerosol. The liquid reservoir 32 replenishes or delivers the liquid matrix to the atomizer 31.

[0159] The reservoir 32 further includes a connector element 322, which is coupled to the opening of the container 321 facing the first end 310. In some embodiments, the connector element 322 extends at least partially into the container 321 and is tightly connected to the container 321 by riveting, interference fit, or other means. A flexible sealing element 328, such as an O-ring, is also arranged between the connector element 322 and the inner wall of the container 321 to provide a seal between them.

[0160] As shown in Figures 22 to 27, the connector element 322 is provided with or arranged with at least two liquid outlet connectors; specifically, the connector element 322 is arranged with:

[0161] A first liquid output connector 323 and a second liquid output connector 324 are arranged at intervals; the first liquid output connector 323 and the second liquid output connector 324 are arranged at intervals along the thickness direction of the atomizing assembly 200 / atomizing assembly 300.

[0162] After assembly, the first liquid output connector 323 and the second liquid output connector 324 are used to be inserted into the atomizer 31, thereby replenishing the liquid matrix of the container 321 and / or the second liquid storage chamber 329 into the first liquid storage chamber of the atomizer 31.

[0163] As shown in Figures 20 to 31, the first liquid output connector 323 and the second liquid output connector 324 are arranged to extend longitudinally. Furthermore, the first liquid output connector 323 and the second liquid output connector 324 extend away from the container. The first liquid output connector 323 and the second liquid output connector 324 are protruding. The first liquid output connector 323 and the second liquid output connector 324 have exposed free ends for insertion into the atomizer 31. The extension lengths of the first liquid output connector 323 and the second liquid output connector 324 are the same.

[0164] Referring to Figure 21, the atomizer 31 is provided with a first liquid input interface 343 and a second liquid input interface 344. When the replenishment part 203 is assembled with the atomizer 31, the first liquid output connector 323 is inserted into the atomizer 31 via the first liquid input interface 343, establishing a first liquid transfer channel that connects the second liquid storage chamber 329 to the first liquid storage chamber of the atomizer 31; the second liquid output connector 324 is inserted into the atomizer 31 via the second liquid input interface 344, establishing a second liquid transfer channel that connects the second liquid storage chamber 329 to the first liquid storage chamber of the atomizer 31. During use, the liquid matrix from the second liquid storage chamber 329 is replenished to the first liquid storage chamber of the atomizer 31 via the first liquid transfer channel and / or the second liquid transfer channel.

[0165] In this embodiment, when the atomizing assembly 200 / 300 is received within the power supply unit, the first liquid output connector 323 / first liquid transfer channel and the second liquid output connector 324 / second liquid transfer channel are spaced apart along the thickness direction. For example, the first liquid output connector 323 / first liquid transfer channel is located between the second liquid output connector 324 / second liquid transfer channel and the front side 150; the second liquid output connector 324 / second liquid transfer channel is located between the first liquid output connector 323 / first liquid transfer channel and the rear side 160. Alternatively, the first liquid output connector 323 / first liquid transfer channel is relatively closer to the front side 150, and the second liquid output connector 324 / second liquid transfer channel is relatively closer to the rear side 160.

[0166] As shown in Figures 20 to 32, the second sealing base 35 of the atomizer 31 is provided with a first connector clearance hole 353 and a second connector clearance hole 354. The first connector clearance hole 353 is aligned with the first liquid input interface 343, and the second connector clearance hole 354 is aligned with the second liquid input interface 344. After the liquid reservoir 32 is assembled with the atomizer 31, the first liquid output connector 323 passes through the first connector clearance hole 353 of the second sealing base 35, extends into the first liquid reservoir, and abuts against the lower surface of the first liquid holding element 316; the second liquid output connector 324 passes through the second connector clearance hole 354 of the second sealing base 35, extends into the first liquid reservoir, and abuts against the lower surface of the first liquid holding element 316.

[0167] In this embodiment, the distal end 120 and / or the first side 130 and / or the second side 140 of the power supply unit and / or the electronic atomizing device are configured to be arc-shaped; and at least a portion of the surfaces of the front side 150 and the rear side 160 of the power supply unit and / or the electronic atomizing device are planar; thus, the power supply unit and / or the electronic atomizing device can only be placed flat or horizontally parallel to the plane defined by the width and thickness directions. The power supply unit and / or the electronic atomizing device cannot be placed vertically on a horizontal platform or placed on its side. When the atomizing assembly 200 / 300 is received within the power supply unit, the electronic atomizing device can only be placed horizontally on a horizontal platform, as shown in Figure 31, for example.

[0168] In use, when the power supply unit and / or electronic atomizing device are placed horizontally on a horizontal platform, one of the front side 150 and the rear side 160 faces upward and the other faces downward. For example, in the horizontal placement shown in Figure 31, the front side 150 faces upward and the rear side 160 faces downward.

[0169] In use, when the power supply unit and / or electronic atomizing device are placed horizontally, one of the first liquid output connector 323 and the second liquid output connector 324 of the atomizing assembly 200 / 300 transfers the liquid matrix while the other provides a channel for air exchange. For example, as shown in Figure 28, when the power supply unit and / or electronic atomizing device are placed horizontally on a horizontal platform, the liquid matrix in the second liquid reservoir 329 of the atomizing assembly 200 / 300 can be replenished to the first liquid reservoir of the atomizer 31 via the first liquid output connector 323 / first liquid transfer channel near the rear side 160, as shown by arrow R51 in Figure 31. As shown by arrow R52 in Figure 31, when the liquid matrix in the second liquid storage chamber 329 is replenished into the first liquid storage chamber of the atomizer 31, the air in the first liquid storage chamber of the atomizer 31 can enter the second liquid storage chamber 329 through the second liquid output connector 324 / second liquid transfer channel to exchange air between the first liquid storage chamber and the second liquid storage chamber 329 of the atomizer 31 to balance the pressure between them.

[0170] As shown in Figures 20 to 31, the atomizing assembly 200 / 300 further includes:

[0171] At least one first capillary element 326 is located within the first liquid output connector 323 / first liquid transfer channel;

[0172] At least one first capillary element 327 is located within the second liquid output connector 324 / second liquid transfer channel.

[0173] In some embodiments, the first capillary element 326 and / or the first capillary element 327 are made of flexible natural capillary fiber material, such as flexible natural cotton fiber or natural nonwoven fiber.

[0174] Alternatively, in some other embodiments, the first capillary element 326 and / or the first capillary element 327 are made of artificial capillary fiber material, such as rigid rayon of polyester fiber, or rigid rayon or artificial foam of filamentous polyurethane.

[0175] The first capillary element 326 and / or the first capillary element 327 of the above-mentioned artificial capillary fiber material have a hardness between that of ordinary natural plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A). Therefore, the structure is stable and has extremely low expansion after absorbing and wetting the liquid matrix. After assembly, the first capillary element 326 and / or the first capillary element 327 can make more stable contact and abut against the inner wall of the first liquid output connector 323 / second liquid output connector 324, so as to prevent the first capillary element 326 and / or the first capillary element 327 from moving within the first liquid output connector 323 / second liquid output connector 324 after assembly.

[0176] In the embodiments, the density of the first capillary element 326 and / or the first capillary element 327 prepared from the artificial capillary fiber material is greater than that of the natural plant cotton / nonwoven fiber; the first capillary element 326 and / or the first capillary element 327 with a relatively large density has a relatively greater ability and efficiency in adsorbing and transferring liquid matrix than the natural plant cotton / nonwoven fiber.

[0177] In use, the first capillary element 326 and the first capillary element 327 can adsorb and buffer the liquid matrix through capillary action to regulate the flow rate of the liquid matrix delivered from the second reservoir 329 to the first reservoir. This can prevent leakage caused by excessively fast flow when replenishing the liquid matrix, and can also release the liquid matrix to ensure the supply rate when the flow is slow.

[0178] As shown in Figures 20 to 31, the free ends of the first capillary element 326 and the first liquid output connector 323 are flush; the free ends of the first capillary element 327 and the second liquid output connector 324 are flush. After assembly, the first capillary element 326 and the first capillary element 327 abut against the lower surface of the first liquid holding element 316, thereby achieving fluid communication with the first liquid holding element 316.

[0179] In the embodiments, the density of the first capillary element 326 and / or the first capillary element 327, made of artificial capillary fiber material, is greater than the density of the first liquid holding element 316.

[0180] As shown in Figures 20 to 31, the first liquid holding element 316 of the atomizer 31 also includes a second capillary element 383 and a second capillary element 384.

[0181] As shown in Figures 20 to 31, the first liquid holding element 316 has a first receiving hole 3163 and a second receiving hole 3164 extending from the upper surface to the lower surface. The second capillary element 383 is received and held within the first receiving hole 3163. The second capillary element 384 is received and held within the second receiving hole 3164.

[0182] In the embodiments, the second capillary element 383 and / or the second capillary element 384 are made of artificial capillary fiber material, such as rigid artificial cotton made of polyester fiber, or rigid artificial cotton or artificial foam made of filamentous polyurethane.

[0183] The second capillary element 383 and / or the second capillary element 384 of the above-mentioned artificial capillary fiber material have a hardness between that of ordinary natural plant cotton / nonwoven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A). In the embodiments, the density of the second capillary element 383 and / or the second capillary element 384 prepared from the artificial capillary fiber material is greater than that of the first liquid retaining element 316 prepared from natural plant cotton / nonwoven fabric fibers; the second capillary element 383 and / or the second capillary element 384 with a relatively large density has a relatively greater ability and efficiency in adsorbing and transferring liquid matrix than the first liquid retaining element 316 prepared from natural plant cotton / nonwoven fabric fibers.

[0184] In use, the second capillary element 383 and / or the second capillary element 384 are used to adsorb and buffer the liquid matrix within the first liquid holding element 316. The second capillary element 383 and / or the second capillary element 384 have a greater liquid adsorption capacity than the first liquid holding element 316 and thus have better liquid-locking ability to prevent the seepage of the liquid matrix supersaturated and adsorbed by the first liquid holding element 316 of the natural cotton fibers.

[0185] As shown in Figures 20 to 31, after assembly, the second capillary element 383 and / or the second capillary element 384 are flush with the upper surface of the first liquid holding element 316. The second capillary element 383 and / or the second capillary element 384 have a distance d11 between them and the lower surface of the first liquid holding element 316. In some embodiments, the distance d11 is approximately between 1 mm and 4 mm.

[0186] As shown in Figures 20 to 31, after assembly, the second capillary element 383 and the first capillary element 326 are longitudinally aligned; however, they are not in contact due to a gap d11 between them. The second capillary element 384 and the first capillary element 327 are also longitudinally aligned; however, they are not in contact due to a gap d11 between them. Therefore, in use, the gap d11 is advantageous in preventing the liquid matrix transferred from the first capillary element 326 to the first liquid holding element 316 from being taken away by the second capillary element 383.

[0187] As shown in Figures 20 to 31, a first capillary groove 3231 is further arranged on the inner surface of the first liquid output connector 323; a second capillary groove 3241 is further arranged on the inner surface of the second liquid output connector 324. The first capillary groove 3231 extends from the free end of the first liquid output connector 323 toward the container 321. The second capillary groove 3241 extends from the free end of the second liquid output connector 324 toward the container 321.

[0188] In this embodiment, the first capillary groove 3231 and the second capillary groove 3241 are arranged to extend substantially longitudinally. The first capillary groove 3231 can be used to form an air exchange channel between the inner surfaces of the first capillary element 326 and the first liquid outlet connector 323. The second capillary groove 3241 can be used to form an air exchange channel between the inner surfaces of the first capillary element 327 and the second liquid outlet connector 324.

[0189] When the liquid matrix in the second liquid storage chamber 329 of container 321 is transferred to the first liquid storage chamber / first liquid holding element 316 through the first capillary element 326, the air in the first liquid storage chamber / first liquid holding element 316 can also exchange air with the second liquid storage chamber 329 through the first capillary groove 3231. Furthermore, when the liquid matrix in the second liquid storage chamber 329 of container 321 is transferred to the first liquid storage chamber / first liquid holding element 316 through the first capillary element 327, the air in the first liquid storage chamber / first liquid holding element 316 can also exchange air with the second liquid storage chamber 329 through the first capillary element 327.

[0190] In some embodiments, the first capillary groove 3231 and / or the second capillary groove 3241 have a depth of approximately 0.5 mm to 2.0 mm and a width of approximately 0.5 mm to 2.0 mm.

[0191] In the embodiment, the air exchange provided by the first capillary groove 3231 and / or the second capillary groove 3241 can bypass the liquid matrix transmitted by the first capillary element 326 / first capillary element 327, which is beneficial for assisting air exchange and maintaining smooth air exchange.

[0192] As shown in Figure 28, the extension length of the first capillary groove 3231 and / or the second capillary groove 3241 is less than the length of the first capillary element 326 / first capillary element 327.

[0193] As shown in Figures 20 to 31, the atomizer 31 is also equipped with:

[0194] The ventilation channel R4 provides a pathway to connect the first liquid reservoir of the atomizer 31 with the external atmosphere or outside air.

[0195] As shown in Figure 30, the ventilation channel R4 includes:

[0196] The first ventilation connection hole 313 is arranged on the main housing 311 and located at the first end 310;

[0197] A ventilation groove 373 is formed or arranged on the first sealing base 37; the ventilation groove 373 is formed on the first surface of the first sealing base 37 facing the first end 310;

[0198] The second ventilation communication hole 374 extends from the ventilation groove 373 through or to the second surface of the first sealing base 37 facing the first liquid storage chamber.

[0199] Alternatively, the ventilation passage R4 may consist of a continuously arranged:

[0200] The first channel section is defined by the first ventilation connection hole 313;

[0201] The second channel is defined by the ventilation groove 373;

[0202] The third channel is defined by the second ventilation connection hole 374.

[0203] The first channel section is connected to the external atmosphere; the third channel section is connected to the first liquid storage chamber; and the second channel section provides communication between the first channel section and the third channel section.

[0204] In one embodiment, the first ventilation connection hole 313 communicates with the external atmosphere; and the port of the first end 310 is defined by the first ventilation connection hole 313 to form a first connection port for communicating with the external atmosphere; thus, the ventilation channel R4 is connected to the external atmosphere by the first ventilation connection hole 313. In another embodiment, the second ventilation connection hole 374 extends through to the first liquid storage chamber and communicates with the first liquid storage chamber; thus, the port of the second surface of the first sealing base 374 defines a second connection port communicating with the first liquid storage chamber.

[0205] Specifically, the second connection port defined by the second venting connection hole 374 communicates with the first liquid storage chamber through a first gap space defined between the upper surface of the first liquid holding element 316 and the first sealing base 37; and the venting passage R4 is connected to the first liquid storage chamber by the second venting connection hole 374. Of the first connection port defined by the first venting connection hole 313 and the second connection port defined by the second venting connection hole 374, one is closer to the front side 150 and the other is closer to the rear side 160.

[0206] In this embodiment, the first ventilation connection hole 313, defined by the first connection port at the first end 310, is arranged at a distance from the air outlet 312. Furthermore, the area of ​​the first connection port is smaller than the area of ​​the air outlet 312.

[0207] In this embodiment, the ventilation groove 373 extends along the thickness direction of the atomizing component 200 / 300. Alternatively, after assembly, the ventilation groove 373 extends along the thickness direction of the electronic atomizing device.

[0208] In the embodiment shown in Figure 30, the ventilation channel R4 connects the first liquid storage chamber of the atomizer 31 to the external atmosphere to balance the pressure between the first liquid storage chamber of the atomizer 31 and the external environment. Specifically, when the atomizing assembly 200 / 300 is subjected to environmental testing or transported at high altitude and low pressure, if the pressure in the first liquid storage chamber is greater than or less than the external pressure, the ventilation channel R4 connects the first liquid storage chamber of the atomizer 31 to the external atmosphere to balance their pressures. Alternatively, during user inhalation, as the liquid matrix in the first liquid storage chamber of the atomizer 31 is consumed and the negative pressure in the first liquid storage chamber gradually increases, the ventilation channel R4 provides a path for outside air to enter the first liquid storage chamber through the first ventilation connection hole 313, thereby alleviating the negative pressure in the first liquid storage chamber of the atomizer 31.

[0209] In the embodiment shown in Figure 30, the first ventilation connection hole 313 is aligned with one end of the ventilation groove 373 along its length, forming an air connection; the second ventilation connection hole 374 is connected to the other end of the ventilation groove 373 along its length. Therefore, the channel path of the ventilation channel R4 is bent. The channel path of the ventilation channel R4 is not straight. Furthermore, both the first channel portion defined by the first ventilation connection hole 313 and the third channel portion defined by the second ventilation connection hole 374 extend longitudinally along the atomizer 31. And the first channel portion defined by the first ventilation connection hole 313 and the third channel portion defined by the second ventilation connection hole 374 are offset relative to each other longitudinally in the atomizer 31.

[0210] In the embodiment shown in Figure 30, the ventilation channel R4 is located between the first liquid reservoir of the atomizer 31 and the first end 310. The ventilation channel R4 does not bypass or cross the first liquid reservoir of the atomizer 31.

[0211] In this embodiment, when the atomizing component 200 / 300 is received within the power supply unit, the first ventilation connection hole 313 connects to the external atmosphere through the gap between the atomizing component 200 / 300 and the first housing 11. Furthermore, when the atomizing component 200 / 300 is received within the power supply unit, the ventilation channel R4 maintains communication between the first liquid storage chamber of the atomizing component 200 / 300 and the atmosphere.

[0212] In an embodiment, as shown in Figure 31, when the power supply unit and / or electronic atomizing device are placed horizontally, one of the first ventilation communication holes 313 and the other of the second ventilation communication holes 374 are near the front side 150 and the other is near the rear side 160, and the ventilation groove 373 of the ventilation channel R4 extends along the thickness direction of the atomizing assembly 200 / 300. Therefore, the liquid matrix in the atomizer 31 cannot flow into the ventilation channel R4 and form a blockage. It is advantageous to keep the ventilation channel R4 open and prevent the liquid matrix from entering when the power supply unit and / or electronic atomizing device are placed horizontally.

[0213] In some embodiments, the ventilation passage R4 is isolated or separate from the airflow passage passing through the atomizer 31.

[0214] Referring to Figure 32, when the atomizing components 200 and 300 are received within the power supply unit, the first ventilation port 313 of the atomizing component 200 and the first ventilation port 313 / first connection port of the atomizing component 300 are far apart from each other. The first ventilation port 313 of the atomizing component 200 is substantially closer to the first side 130, and the first ventilation port 313 of the atomizing component 300 is substantially closer to the second side 140.

[0215] In this embodiment, when the atomizing component 200 is received within the power supply unit, the first ventilation connection hole 313 of the atomizing component 200 is located between the airflow channel of the atomizing component 200 and the first side 130. When the atomizing component 300 is received within the power supply unit, the first ventilation connection hole 313 of the atomizing component 300 is located between the airflow channel of the atomizing component 300 and the second side 140.

[0216] When the atomizing assembly 200 is received within the power supply body, the first ventilation connection hole 313 of the atomizing assembly 200 is located between the longitudinal central axis of the power supply body and the rear side 160. When the atomizing assembly 300 is received within the power supply body, the first ventilation connection hole 313 of the atomizing assembly 300 is located between the longitudinal central axis of the power supply body and the front side 150.

[0217] The distance between the first ventilation port 313 of the atomizing component 200 and the front side 150 is greater than the distance between it and the rear side 160; the distance between the first ventilation port 313 of the atomizing component 300 and the front side 150 is less than the distance between it and the rear side 160. The distance between the first ventilation port 313 of the atomizing component 200 and the front side 150 is greater than the distance between the first ventilation port 313 of the atomizing component 300 and the front side 150.

[0218] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application.
