Description

atomizer Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer. Background Technology

[0002] Atomizers are a common type of electronic product used to heat and atomize an aerosol-forming matrix to form an aerosol. The air passage serves as the channel for expelling the aerosol and providing it to the user.

[0003] In related technologies, when aerosols flow through the airway, due to the Coanda effect (also known as the wall adhesion effect), most aerosols adhere to the airway wall during transport. The airway wall exerts frictional resistance and low temperature on the aerosols, causing a large number of aerosol particles to condense and adhere to the airway wall. Therefore, this not only affects the performance and lifespan of the atomizer but also makes it easier for users to inhale the aerosol into their mouths, resulting in a poor user experience. Summary of the Invention

[0004] In view of this, this application provides an atomizer to solve the problem of aerosol condensation easily occurring in the air passage of atomizers in the related art.

[0005] An embodiment of this application discloses an atomizer, which includes an exhaust duct, an atomizing air duct, and a splitting air duct. The outlet end of the atomizing air duct is connected to the exhaust duct. The outlet end of the splitting air duct is at least connected to the atomizing air duct, and the outlet direction of at least part of the airflow from the splitting air duct intersects the airflow direction of the exhaust duct.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The applicant discovered that in the atomizer of the relevant technology, during the process of airflow passing through the atomizing core 6 to form an aerosol, the airflow inevitably needs to travel a certain distance. This causes the airflow to be rectified in this section of the airway, forming an aerosol that tends to flow along the surface of the airway. This further causes the aerosol to easily flow along the wall in the last section of the exhaust airway.

[0033] As shown in Figures 1-6, this application embodiment provides an atomizer, including a main body 7 and an atomizing core 6. The main body 7 has a liquid storage chamber 101, an atomizing air passage 102, a diversion air passage 103, and an exhaust passage 104 inside. The liquid storage chamber 101 stores the aerosol forming matrix, and the main body 7 has an air inlet 106. The atomizing air passage 102 and the diversion air passage 103 are connected in parallel between the air inlet 106 and the exhaust passage 104; that is, the atomizing air passage 102 connects the air inlet 106 and the exhaust passage 104, and the diversion air passage 103 also connects the air inlet 106 and the exhaust passage 104. The atomizing core 6 is disposed within the main body 7 and has an atomizing surface 601 exposed in the atomizing air passage 102. The atomizing core 6 can absorb the aerosol forming matrix and heat and atomize it on the atomizing surface 601 to form an aerosol. At least part of the airflow from the split airway 103 flows into the intersection of the atomizing airway 102, the split airway 103 and the exhaust airway 104 along a first direction w (i.e., the fourth direction w below) parallel to the atomizing surface. The first direction w intersects the extension direction (i.e. the air guiding direction) of the exhaust airway 104.

[0034] The applicant found that an airflow stagnation zone is easily formed at the intersection of the atomizing airway 102 and the exhaust airway 104. In addition, due to the tendency of aerosols to adhere to the wall for transport, aerosols are prone to remain at this point, forming eddies and condensing, especially the corner eddies formed on both sides of the atomizing surface 601. In this application, through the user's suction action, the airflow entering the atomizer does not simply pass through the atomizing airway 102 to form an aerosol, but the airflow is split into two. One part of the airflow flows through the atomizing airway 102 and passes through the atomizing core to form an aerosol, while the other part of the airflow flows through the splitting airway 103. At least part of the airflow from the splitting airway 103 flows into the intersection of the atomizing airway 102, the splitting airway 103, and the exhaust channel 104 along the first direction w. The first direction w is parallel to the atomizing surface 601 and intersects the extension direction of the exhaust channel 104. This allows the airflow from the splitting airway 103 to carry out the aerosol in the airflow stagnation area at the intersection, and allows this part of the aerosol to flow into the exhaust channel 104 along with the aerosol in the atomizing airway 102, reducing the aerosol condensation at the intersection. At the same time, the airflow from the split airway 103 also disturbs the aerosol from the atomizing airway 102, breaking the original flow state of the aerosol that tends to adhere to the wall at the intersection, thereby preventing the aerosol from adhering to the wall in the exhaust airway 104, and thus reducing the phenomenon of aerosol condensation in the exhaust airway 104. This solves the problem of aerosol condensation in the airway of the atomizer in related technologies, and improves the performance and lifespan of the atomizer, while also enhancing the user experience.

[0035] It should be noted that, regarding the junction of the atomizing airway 102, the diverting airway 103 and the exhaust airway 104, due to the diffuse nature of the airflow, the junction can specifically refer to the inlet of the exhaust airway 104, or the area outside the exhaust airway 104 that is close to the inlet of the exhaust airway 104, or the position in the exhaust airway 104 that is close to the inlet of the exhaust airway 104. This application does not make any specific limitation.

[0036] Furthermore, in some types of atomizers, the airflow path design, due to internal structural limitations, can exhibit abrupt changes in the airflow surface. For example, at the connection between the atomizing airflow path 102 and the exhaust airflow path 104, the airflow encounters a sudden change in the airflow surface, resulting in a significant reverse vortex near the inlet of the exhaust airflow path 104, as shown in Figure 8. This traps some aerosol within the vortex, preventing it from reaching the atomizer's outlet, thus reducing aerosol concentration and increasing condensation on the airflow path walls. The atomizer provided in this application, however, introduces an additional airflow from the split airflow path 103 at the connection between the atomizing airflow path 102 and the exhaust airflow path 104. This airflow from the split airflow path 103 impacts the aerosol at the intersection of the atomizing airflow path 102, the split airflow path 103, and the exhaust airflow path 104, significantly reducing the reverse vortex area. From this perspective, it also solves the problems of reduced aerosol concentration and increased condensation on the airflow path walls.

[0037] Furthermore, to ensure a smooth inhalation experience for the user, the atomizing airway 102 and the exhaust airway 104 are generally positioned opposite or substantially opposite each other along the airflow direction, or in other words, the extension directions of the atomizing airway 102 and the exhaust airway 104 are almost identical. The atomizing core 6 in this application can specifically take the form of a planar atomizing core, a columnar atomizing core, etc. The illustration shows an example of the atomizing core 6 being a planar atomizing core.

[0038] Regarding the relationship between the first direction w and the extension direction of the exhaust duct 104, in some optional embodiments, as shown in Figures 4-6, the first direction w (i.e., the fourth direction w below) can be perpendicular to the extension direction of the exhaust duct 104, that is, at least part of the airflow of the split air duct 103 is injected perpendicular to the direction of aerosol flow; of course, it is also feasible for the first direction w to have a small angle with the extension direction of the exhaust duct 104.

[0039] Regarding the relationship between the extension direction of the exhaust duct 104 and the atomizing surface 601, the atomizing surface 601 is inclined relative to the exhaust duct 104, as shown in Figure 5; in some other feasible embodiments, the atomizing surface 601 may be parallel to the exhaust duct 104.

[0040] In some embodiments, the effective flow area at the outlet of the split air duct 103 is smaller than the effective flow area at the inlet of the split air duct 103. Specifically, it can be configured such that the effective flow area of ​​the split air duct 103 decreases in a stepwise or gradual manner from the inlet to the outlet, or the effective flow area of ​​the split air duct 103 near the outlet is reduced. In this application, the effective flow area refers to the area actually involved in the flow when the airflow passes through the cross-sections of the inlet and outlet.

[0041] With this configuration, the outlet of the split airway 103 can form a pressurized structure, and the airflow is ejected at a high velocity at the outlet of the split airway 103. In this way, a small amount of airflow in the split airway 103 can effectively impact the aerosol from the atomizing airway 102, effectively influencing and changing the flow direction of the aerosol from the atomizing airway 102, thereby achieving the purpose of using a small flow of airflow to influence the flow direction of the aerosol from the atomizing airway 102.

[0042] In some embodiments, the effective flow volume of the split airway 103 is less than or equal to 30% of the effective flow volume of the inlet 106. In this application, the effective flow volume refers to the volume of airflow passing through a certain cross-section within a certain time period. The ratio of the effective flow volume of the split airway 103 to the effective flow volume of the inlet 106 represents the proportion of airflow entering the split airway 103 and the atomizing airway 102 respectively through the inlet 106.

[0043] This configuration ensures that most of the airflow entering the air inlet 106 enters the atomizing airway 102, guaranteeing sufficient airflow in the atomizing airway 102 to ensure that the amount of aerosol generated in the atomizing airway 102 reaches the expected level, resulting in a better taste.

[0044] Regarding how the atomizing airway 102 and the diverting airway 103 are separated and formed, in some embodiments, the main body 7 is provided with an airflow separator 5 that is assembled and connected to the main body 7, as shown in Figures 5, 6, and 7. The airflow separator 5 cooperates with the atomizing core 6 to form the atomizing airway 102, and the airflow separator 5 cooperates with the main body 7 to form the diverting airway 103. That is, the airflow separator 5 divides a portion of the space between the air inlet 106 and the exhaust duct 104 into the atomizing airway 102 and the diverting airway 103. The airflow separator 5 can be made of silicone.

[0045] This configuration, by designing an airflow separator 5 that is structurally independent and can be assembled with the main body 7, forms the atomizing airway 102 and the diversion airway 103. This simplifies the structural design of the main body 7 itself and facilitates the overall assembly of the atomizer.

[0046] Of course, in addition to the above-mentioned method of assembling the airflow separator 5 inside the main body 7, it is also feasible to have an integrally formed air passage structure inside the main body 7 to serve as the atomizing air passage 102 and the diversion air passage 103.

[0047] In a specific embodiment, as shown in FIG6, the diversion air passage 103 includes a first channel 1031 and a second channel 103a. The first channel 1031 is formed on the airflow separator 5, communicates with the air inlet 106 and extends away from the air inlet 106. Specifically, the extension direction of the first channel 1031 may be the same as the extension direction of the exhaust passage 104, and the inlet of the first channel 1031 is the inlet of the diversion air passage 103. The second channel 103a is formed on the airflow separator 5, communicates with the first channel 1031 and extends towards the exhaust passage 104, and the outlet of the second channel 103a is the outlet of the diversion air passage 103. The first channel 1031 and the second channel 103a may be grooves formed on the surface of the airflow separator 5 or hollow channels formed inside the airflow separator 5. For ease of understanding, when the atomizer is placed vertically along its length, the first channel 1031 can be regarded as the vertical channel portion, and the second channel 103a can be regarded as the horizontal channel portion.

[0048] With this configuration, by designing the airflow separator 5 in an irregular shape, a diversion airflow channel 103 with reversible airflow direction is formed, making full use of the limited space inside the main body 7, so as to guide part of the airflow from the air inlet 106 to the connection between the exhaust channel 104 and the atomizing airflow channel 102.

[0049] In one embodiment, the second channel 103a is provided to extend along a plane perpendicular to the extension direction of the exhaust channel 104 or satisfying the perpendicular condition.

[0050] With this configuration, when the airflow is ejected from the second channel 103a of the split airway 103, its flow direction is perpendicular to the flow direction of the aerosol from the atomizing airway 102. Under the same airflow rate, the ejected airflow has a strong disturbance ability on the aerosol from the atomizing airway 102, and will not affect the user's smooth inhalation.

[0051] In another preferred embodiment, the second channel 103a includes a main channel section 1032 and a branch channel section 1033; the main channel section 1032 is connected to the first channel 1031; the branch channel section 1033 is connected to the main channel section 1032 and is provided with multiple outlets connected to the atomizing air channel 102, so that the diversion air channel 103 forms multiple outlets.

[0052] With this configuration, the airflow of the split airway 103 is ejected in multiple directions to impact the aerosol from the atomization channel at multiple angles, so that the aerosol is more fully disturbed before entering the exhaust channel 104, further improving the effect of preventing aerosol condensation in the exhaust channel 104.

[0053] Based on this, by setting the branch section 1033 to be narrower than the main section 1032, the diversion airway 103 can be made into a pressurized airway.

[0054] In conjunction with the above embodiments, in order to make the pressurization effect of the branch airway 103 obvious, the effective flow area of ​​the first channel 1031 can be set to be greater than the effective flow area of ​​the main channel section 1032 of the second channel 103a, and the effective flow area of ​​the main channel section 1032 of the second channel 103a can be greater than the effective flow area of ​​the branch channel section 1033 of the second channel 103a.

[0055] In some examples, the outlets of at least two branch sections 1033 can be symmetrically arranged about the main section 1032 in the first direction w, or the outlets of at least two branch air passages 103 can be arranged opposite to the outlets of the atomizing air passage 102. In this way, while enhancing the disturbance effect on aerosols, the feasibility of designing and manufacturing the airflow separator 5 is ensured.

[0056] In addition, the branch section 1033 can be set to an arc shape or a straight shape. When the branch section 1033 is designed to be arc-shaped and has two symmetrical branch sections 1033, the outlet of the atomizing air passage 102 can be opened in the inner area surrounded by the branch section 1033, which is conducive to the compact and small structure of the airflow separator 5 and brings high feasibility to the structural design of the airflow separator 5.

[0057] In some alternative embodiments, the atomizing surface 601 is arranged obliquely relative to the exhaust duct 104. At least one branch section 1033 has an outlet as an impact port 1034. The impact port 1034 is located at the center of the atomizing surface 601 near the exhaust duct 104, and has a gradually expanding guide surface 1035 on the side wall or an oblique guide surface 1036 on the bottom wall, or both. As shown in FIG7, the gradually expanding guide surface 1035 causes the impact port 1034 to flare out.

[0058] With this configuration, the impingement port 1034 has an inclined guide surface 1036 relative to the exhaust duct 104, which guides part of the airflow in the branch section 1033 through the impingement port 1034 to impact the aerosol, thereby reducing the horizontal component of the aerosol. This reduces the contact between the aerosol in the atomizing air duct 102 and the inner wall of the exhaust duct 104 when it enters, thus reducing the occurrence of aerosol exothermic formation of condensate. The gradually expanding guide surface 1035 can increase the contact area between the airflow through the impingement port 1034 and the aerosol, improving the anti-wall-adhering flow effect of the airflow on the outermost aerosol.

[0059] In some other embodiments, the atomizing airway 102 includes an atomizing groove 1021 formed on the airflow separator 5. Referring to FIG23, the atomizing core 6 includes a heating part 602 and a pressing part 603 located on both sides of the heating part 602. It can also be said that the atomizing core 6 is a planar atomizing core. The heating part 602 is opposite to the atomizing groove 1021, and the pressing part 603 is fitted and connected to the airflow separator 5.

[0060] With this design, the atomizing airway 102 is in the form of a groove on the airflow separator 5, making it easy for the airflow separator 5 to be adapted to the planar atomizing core to construct the atomizing airway 102. Moreover, it also makes the assembly between the airflow separator 5 and the planar atomizing core highly feasible.

[0061] In some optional embodiments, a buffer space 105 is provided between the air inlet 106 and the airflow separator 5. The atomizing air passage 102 and the diverting air passage 103 are both connected to the buffer space 105. That is, the inlet of the atomizing air passage 102 and the inlet of the diverting air passage 103 are both separated from the air inlet 106 by a certain distance.

[0062] With this configuration, after the airflow enters the main body 7 through the air inlet 106, the airflow passes through the buffer space 105 and then flows into the atomizing airway 102 and the diversion airway 103 respectively. On the one hand, this can reduce the resistance of the airflow entering the atomizing airway 102 and the diversion airway 103; on the other hand, this buffer space 105 provides a larger connection area, providing more feasible design positions for the inlet of the atomizing airway 102 and the inlet of the diversion airway 103, which is conducive to simplifying the structural design of the airflow separator 5.

[0063] In some embodiments, the main body 7 is an assembly component structure, including a shell 1, an empty tube 2, a support 3, and a base 4 (i.e., a sealing plug); the shell 1 is in the shape of an empty rod, and an assembly port 11 is provided at the bottom of the shell 1; the empty tube 2 passes through the shell 1, with one end of the empty tube 2 located in the shell 1 and the other end communicating with the outside, so as to form an exhaust channel 104 in the empty tube 2; the support 3 is assembled and connected to the shell 1 and the empty tube 2 (for example, the support 3 is connected between the shell 1 and the empty tube 2), so as to construct a liquid storage chamber 101 between the empty tube 2 and the shell 1; the base 4 is connected to the assembly port 11, and an air inlet 106 is provided in the base 4. An airflow separator 5 is connected between the support 3 and the base 4, and a diversion airway 103 is formed between the airflow separator 5 and the support 3. The support 3 presses the atomizing core 6 onto the airflow separator 5, so as to form an atomizing airway 102 between the atomizing core 6 and the airflow separator 5. This configuration, through the assembly and connection of multiple components, forms the main body 7, which facilitates the assembly of the airflow separator 5 in the main body 7 and also improves the feasibility of the atomizer provided in this application in production assembly.

[0064] Of course, besides the above methods, it is also feasible for the bracket 3 and the outer shell 1 to be integrally formed. In addition, the outer shell 1 and the hollow tube 2 can be integrally formed structures or assembled connections.

[0065] Based on the above implementation methods, the airflow state in the split air passage 103 is shown in Figure 10. After verification, the atomizer provided by this application can significantly improve the corner vortex formed on both sides of the atomizing surface 601; and significantly improve the reverse vortex phenomenon in the exhaust passage 104, reducing the reverse vortex area by more than 70%, as shown in Figure 9.

[0066] This application embodiment also provides an atomizer, which includes a main body 7 and an atomizing core 6. The main body 7 has a liquid storage chamber 101 for storing an aerosol forming matrix, an atomizing air channel 102, a diversion air channel 103, and an exhaust air channel 104 inside. One end of the atomizing air channel 102 and the diversion air channel 103 are respectively connected to the exhaust air channel 104, and the other end of each is respectively connected to the outside. For example, they can be connected to the outside through a common air inlet 106, or they can be connected to the outside through different air inlets. The atomizing core 6 is disposed in the main body 7 and has an atomizing surface 601 exposed in the atomizing air channel 102. The atomizing surface 601 is planar and inclined relative to the exhaust air channel 104. The atomizing core 6 can absorb the aerosol forming matrix and heat and atomize it on the atomizing surface 601 to form an aerosol. At least part of the airflow from the split airway 103 flows into the intersection of the atomizing airway 102, the split airway 103 and the exhaust airway 104 along a first direction w parallel to the atomizing surface 601, the first direction w being perpendicular to the extension direction of the exhaust airway 104.

[0067] Other specific embodiments of this atomizer can be found in the embodiments described above, and will not be repeated here. The beneficial effects of the atomizer can be found in the description of the atomizer described above, and will not be repeated here.

[0068] In other specific embodiments, the atomizer in the above embodiments may further include a power supply component. The main body 7 is connected to the power supply component, and the power supply component is electrically connected to the atomizing core 6. The main body 7 and the power supply component may be connected by detachable methods, including but not limited to magnetic attraction, screw connection, snap-fit, etc., or by non-detachable methods. This application does not specifically limit this aspect.

[0069] An atomizer is a device that atomizes a medium into an aerosol. The atomizer has an atomization channel and an exhaust channel. One end of the atomization channel is for air intake, and the other end is connected to the exhaust channel. The atomized medium mixes with the gas in the atomization channel to form an aerosol, which then flows out through the exhaust channel.

[0070] In the atomizers of this technology, the extension directions of the atomization channel and the air outlet channel intersect, causing the aerosol in the atomization channel to collide with the wall of the air outlet channel when it flows into the air outlet channel. This results in obstructed airflow, and the impact of the aerosol on the wall of the air outlet channel also causes particulate matter in the aerosol to be adsorbed onto the inner wall of the air outlet channel, generating a large amount of condensate.

[0071] As shown in Figures 11 to 22, this application embodiment provides an atomizer that can be used in electronic cigarettes. The provided atomizer includes an exhaust channel 100 (i.e., an exhaust duct), an atomization channel 200 (i.e., an atomization airway), and a diversion channel 300 (i.e., a diversion airway).

[0072] The air outlet channel 100 is guided by the first direction a, and the air outlet channel 100 is connected to the outside atmosphere. The outlet end of the atomizing channel 200 is connected to the air outlet channel 100, and the air outlet end of the atomizing channel 200 is guided by the second direction b, which intersects with the first direction a.

[0073] The outlet end of the diversion channel 300 is connected to the atomizing channel 200. The air guiding direction of the outlet end of the diversion channel 300 is a third direction c, which intersects with the first direction a and the second direction b.

[0074] In this structure, when the gas in the diversion channel 300 flows into the atomization channel 200, it can impact the airflow in the atomization channel 200 and collide with the airflow in the atomization channel 200, changing the direction of the airflow when the airflow in the atomization channel 200 enters the outlet channel 100.

[0075] In this embodiment, the airflow in the diversion channel 300 can reduce the component of the airflow in the atomization channel 200 in the direction perpendicular to the first direction a when it enters the outlet channel 100.

[0076] Specifically, as shown in Figure 11, in the direction perpendicular to the first direction a, the component of the airflow at the outlet end of the diversion channel 300 is the first component c1, and the component of the airflow at the outlet end of the atomizing channel 200 is the second component b1. The directions of the first component c1 and the second component b1 are opposite, and the absolute value of the sum of the first component c1 and the second component b1 is less than the absolute value of the second component b1, so that the airflow in the diversion channel 300 reduces the component of the airflow in the atomizing channel 200 in the direction perpendicular to the first direction a when it enters the outlet channel 100.

[0077] When the magnitudes of the first component c1 and the second component b1 are equal, the airflow in the split channel 300 can eliminate the component of the airflow in the atomizing channel 200 that is perpendicular to the first direction a when it enters the outlet channel 100. In other words, when the magnitudes of the first component c1 and the second component b1 are equal, the total airflow formed by the merging of the airflow in the split channel 300 and the airflow in the atomizing channel 200 flows along the first direction a, minimizing the formation of condensate.

[0078] In the atomizer of this application embodiment, a diversion channel 300 is added. The airflow within the diversion channel 300 can reduce the component of the airflow in the atomization channel 200 perpendicular to the first direction a when it enters the outlet channel 100. This prevents the aerosol from impacting the wall of the outlet channel 100 when flowing from the atomization channel 200 to the outlet channel 100, or reduces the impact force of the aerosol on the inner wall of the outlet channel 100 when flowing from the atomization channel 200 to the outlet channel 100. This reduces the kinetic energy of particulate matter in the smoke impacting the inner wall of the outlet channel 100 when using the atomizer, and reduces the generation of condensate. Therefore, the embodiment of this application can solve the problem in the related art where the extension directions of the atomization channel and the outlet channel of the atomizer intersect, and the aerosol in the atomization channel collides with the wall of the outlet channel when flowing to the outlet channel, generating condensate.

[0079] Referring to Figures 11 and 12, in this embodiment, the second direction b can have a first angle α with the first direction a in a counterclockwise direction, where the first angle α is an acute angle. The third direction c can have a second angle β with the first direction a in a clockwise direction, where the second angle β can be an acute angle or a right angle; that is, the second angle β is greater than 0° and less than or equal to 90°. The first angle α can be equal to or unequal to the second angle β; this is not a limitation herein.

[0080] It should be noted that the first angle α between the second direction b and the first direction a along the counterclockwise direction refers to the angle of rotation when the line containing the second direction b is rotated counterclockwise to the position of the line containing the first direction a, with the line containing the second direction b as the starting point, the line containing the first direction a as the ending point, and the intersection point of the lines containing the first direction a and the second direction b as the center of rotation.

[0081] The second angle β between the third direction c and the first direction a in a clockwise direction refers to the angle of rotation when the line containing the third direction c is rotated clockwise to the position of the line containing the first direction a, with the line containing the third direction c as the starting point, the line containing the first direction a as the ending point, and the intersection point of the first direction a and the line containing the third direction c as the center of rotation.

[0082] In this structure, in the first direction a and its opposite extension direction, the airflow component at the outlet end of the diversion channel 300 is the third component c2, which is in the same direction as the first direction a. The airflow component at the outlet end of the atomizing channel 200 is the fourth component b2, which is in the same direction as the first direction a. In this way, it is possible to prevent the outlet end of the atomizing channel 200 and the outlet end of the diversion channel 300 from generating airflow opposite to the first direction a, thereby ensuring that the airflow in the diversion channel 300 enters the atomizing channel 200 and the total airflow formed by the merging of the airflow in the atomizing channel 200 can smoothly enter the outlet channel 100.

[0083] In the above scheme, the outlet end of the diversion channel 300 is connected to the atomizing channel 200. In one embodiment, the outlet end of the diversion channel 300 can be opened on the wall surrounding the outlet end of the atomizing channel 200, that is, the outlet end of the diversion channel 300 can be located at the outlet end of the atomizing channel 200.

[0084] In this case, if the outlet end of the diversion channel 300 is not located at the inlet end or the middle part of the atomizing channel 200, the total airflow formed after the airflow in the atomizing channel 200 and the airflow in the diversion channel 300 are mixed, the outlet end of the atomizing channel 200 is guided again to be an airflow along the second direction b.

[0085] In some embodiments, as shown in FIG17, in a fourth direction W that is perpendicular to the first direction a, the second direction b, and the third direction c, the width of the outlet end of the diversion channel 300 can be a first width W1, and the width of the outlet end of the atomizing channel 200 can be a second width W2. The first width W1 can be greater than or equal to the second width W2.

[0086] Optionally, if the outlet end of the diversion channel 300 is located on the wall surrounding the outlet end of the atomizing channel 200, the first width W1 can be equal to the second width W2. If, along the airflow direction within the atomizing channel 200, the outlet end of the diversion channel 300 is downstream of the outlet end of the atomizing channel 200, the first width W1 can be greater than the second width W2.

[0087] The width of the outlet end of the diversion channel 300 is greater than or equal to the width of the outlet end of the atomizing channel 200. This prevents the problem that the part of the airflow at the edge of the atomizing channel 200 cannot be weakened or canceled by the airflow impact in the diversion channel 300, and ensures the reduction effect on the component of the airflow in the atomizing channel 200 perpendicular to the first direction a.

[0088] Optionally, the outlet end of the diversion channel 300 may be opposite to the wall of the atomizing channel 200 with the atomizing core 520. In some examples, along the airflow direction within the atomizing channel 200, the outlet end of the diversion channel 300 may be opposite to the downstream of the heating zone of the atomizing core 520.

[0089] Along the air guiding direction of the diversion channel 300, the outlet end of the diversion channel 300 can be a flared structure, and the width of the flared structure gradually increases in the fourth direction W. This structure can increase the impact area of ​​the diversion channel 300 on the atomizing channel 200 at the confluence of the atomizing channel 200 and the diversion channel 300.

[0090] To ensure airflow within the atomizing channel 200 and the diversion channel 300, the inlets of both the atomizing channel 200 and the diversion channel 300 are connected to the outside atmosphere. Optionally, the inlets of the atomizing channel 200 and the diversion channel 300 can be directly connected to the outside atmosphere, or the inlets of the atomizing channel 200 and the diversion channel 300 can each be connected to the outside atmosphere through an air intake channel 400. In other words, the atomizer can have two air intake channels 400.

[0091] In another alternative embodiment, the atomizer may be provided with an air intake channel 400, which is connected to the outside atmosphere. The inlet end of the atomization channel 200 and the inlet end of the diversion channel 300 may both be connected to the air intake channel 400. That is, the atomizer has an air intake channel 400. This structure can reduce the number of openings on the atomizer and help to seal the atomizer.

[0092] When the atomizing channel 200 and the diversion channel 300 are connected to the outside atmosphere through the same air intake channel 400, the flow rate of the diversion channel 300 can be less than that of the atomizing channel 200. This allows more gas entering the atomizer to enter the atomizing channel 200, thus enabling more gas to mix with the atomized liquid to form an aerosol and improve the user experience.

[0093] Optionally, the ratio of the flow rate of the diversion channel 300 to the flow rate of the atomizing channel 200 can be 3:7, so as to ensure that the atomizing channel 200 effectively carries out the aerosol within the atomizing channel 200, and that the airflow from the diversion channel 300 entering the atomizing channel 200 and the airflow from the atomizing channel 200 entering the outlet channel 100 do not cause excessive impact and dilution, thereby reducing the amount of aerosol entering the outlet channel 100. Of course, the ratio of the flow rate of the diversion channel 300 to the flow rate of the atomizing channel 200 can be adjusted according to specific circumstances, and this application does not impose any restrictions on this.

[0094] In this embodiment, the intake channel 400 can be a channel of equal diameter or a channel of unequal diameter. For example, the area of ​​the intake port of the intake channel 400 can be larger than the area of ​​the outlet of the intake channel 400. This structure helps to increase the flow rate of gas in the outlet of the intake channel 400, thereby increasing the overall intake speed of the intake channel 400.

[0095] The area of ​​the cross section of the diversion channel 300 perpendicular to its own air guiding direction can be the first area, that is, the cross-sectional area of ​​the diversion channel 300 is equal everywhere.

[0096] In other alternative embodiments, the cross-sectional area of ​​the diversion channel 300 perpendicular to the gas guiding direction can be gradually reduced along the gas guiding direction of the diversion channel 300 to increase the gas flow rate at the outlet end of the diversion channel 300.

[0097] Referring to Figures 18 to 22, the atomizer structure includes an oil cup 600 and an atomizing component 500.

[0098] The oil cup 600 has an inner cavity, and an air outlet pipe 610 is provided in the inner cavity. The cavity of the air outlet pipe 610 forms at least a partial air outlet channel 100, and the outlet end of the air outlet pipe 610 forms a suction nozzle 611, which is connected to the outside atmosphere.

[0099] The atomizing component 500 is located in the inner cavity. The atomizing component 500 has at least a portion of the atomizing channel 200 and the diversion channel 300. The atomizing component 500 also has a connecting hole 511 that cooperates with the air outlet pipe 610. The atomizing channel 200 and the diversion channel 300 are connected to the air outlet channel 100 through the connecting hole 511.

[0100] Optionally, the outlet end of the atomizing channel 200 can be opposite to the connecting hole 511, and the inlet end of the air outlet pipe 610 can extend into the connecting hole 511, so that the atomizing channel 200 is connected to the lumen of the air outlet pipe 610 through the connecting hole 511, the diversion channel 300 is connected to the atomizing channel 200, and then connected to the air outlet channel 100 through the atomizing channel 200; or, the outlet end of the atomizing channel 200 can be opposite to the connecting hole 511, the inlet end of the air outlet pipe 610 can be opposite to the connecting hole 511, and the connecting hole 511 can form a partial air outlet channel 100, so that the atomizing channel 200 and the air outlet channel 100 are connected, the diversion channel 300 is connected to the atomizing channel 200, and then connected to the air outlet channel 100 through the atomizing channel 200.

[0101] In one optional embodiment, the atomizing channel 200 may be partially disposed on the atomizing component 500 and partially disposed on the oil cup 600, with the two parts connected to form a complete atomizing channel 200. The portion of the atomizing channel 200 disposed on the oil cup 600 is connected to the external atmosphere, forming the air inlet end (inlet end) of the atomizing channel 200. Similarly, the diversion channel 300 may be partially disposed on the atomizing component 500 and partially disposed on the oil cup 600, with the two parts connected to form a complete diversion channel 300. The portion of the diversion channel 300 disposed on the oil cup 600 is connected to the external atmosphere, forming the air inlet end of the diversion channel 300.

[0102] Referring to Figures 18 and 19, in another optional embodiment, the atomizing channel 200 and the diversion channel 300 can both be disposed on the atomizing assembly 500, and the atomizing assembly 500 can include a support 510. The support 510 can be made of a flexible material such as silicone, giving the support 510 itself sealing properties. The outer wall of the support 510 can be sealed to the inner wall of the oil cup 600, so that the inner wall of the oil cup 600, the outer wall of the air outlet 610, and the support 510 together form a sealed liquid storage chamber 620. The liquid storage chamber 620 is used to store the atomizing medium, such as e-liquid, oil, or other atomizing liquid. This structure can improve the sealing performance between the atomizing assembly 500 and the oil cup 600, thereby improving the sealing performance of the atomizer.

[0103] The atomizing assembly 500 also includes an air passage 540 (i.e., an airflow separator), the bracket 510 is provided with an installation chamber and a connecting hole 511 communicating with the installation chamber, the air passage 540 is disposed in the installation chamber, and at least a portion of the atomizing channel 200 is formed in the air passage 540, and at least a portion of the diversion channel 300 is formed in the air passage 540.

[0104] Referring to Figures 21 and 22, the atomizing assembly 500 also includes an atomizing core 520. In an optional embodiment, the air passage component 540 may be provided with a first air guiding recess 541, and the atomizing core 520 is disposed in the mounting chamber. The first air guiding recess 541 may be opposite to the atomizing core 520, and the first air guiding recess 541 may cooperate with the atomizing core 520 to form an atomizing channel 200. That is, the atomizing core 520 forms a portion of the atomizing channel 200, and the surface of the atomizing core 520 that forms the atomizing channel 200 (i.e., the atomizing surface) intersects with the first direction a.

[0105] The atomizing core 520 is used to heat and atomize the atomizing medium. The atomized atomizing medium mixes with the gas in the atomizing channel 200 to form an aerosol. In the embodiment where the first gas guide recess 541 and the atomizing core 520 form the atomizing channel 200, in order to allow the atomizing medium to enter the atomizing core 520, an oil passage hole 512 can be opened on the wall of the mounting chamber. The outer port of the oil passage hole 512 is exposed in the liquid storage chamber 620. The atomizing core 520 can abut against the inner wall of the mounting chamber, and a local area of ​​the atomizing core 520 is opposite to the oil passage hole 512, so that the atomizing medium in the liquid storage chamber 620 can enter the atomizing core 520 through the oil passage hole 512.

[0106] Specifically, the atomizing core 520 may include an oil guide body 521 and a heating element 522. The oil guide body 521 has an absorption surface facing the oil passage 512 and an atomizing surface opposite to the absorption surface. The heating element 522 is disposed on the atomizing surface of the oil guide body 521. The oil guide body 521 and the heating element 522 can be connected to the air passage component 540 by means of snap-fit ​​or other methods (for example, the air passage component 540 has snap-fit ​​protrusions, and the oil guide body 521 and the heating element 522 can have snap-fit ​​grooves, which are snap-fitted together). The oil passage 512 abuts against the inner wall of the mounting chamber and communicates with the liquid storage chamber 620. The heating element 522 can face the first air guide recess 541. It can be understood that the heating element 522 and the oil guide body 521 can also be clamped between the inner wall of the air passage component 540 and the support 510.

[0107] In this embodiment, the atomizing core 520 can be a flat structure, including a plate-shaped oil guide 521 and a heating element 522, with the heating element 522 disposed on one side surface of the oil guide 521.

[0108] In another optional embodiment, the air passage 540 may be provided with a first perforation, the atomizing channel 200 includes the first perforation, the first perforation penetrates the air passage 540, and the two ports of the first perforation are provided on the outer wall surface of the air passage 540 to form the inlet end and outlet end of the atomizing channel 200 respectively, and the atomizing core 520 may be located in the first perforation.

[0109] In this embodiment, the atomizing core 520 can be a columnar structure, including a hollow columnar oil guide body 521 and a heating element 522, with the heating element 522 disposed on the inner wall of the oil guide body 521; or, the atomizing core 520 can also be a flat structure, including a plate-shaped oil guide body 521 and a heating element 522, with the heating element 522 disposed on one side surface of the oil guide body 521.

[0110] In an optional embodiment, where all the flow channels 300 are disposed on the atomizing assembly 500, the air passage 540 may be provided with a second air guide recess 542. The second air guide recess 542 may be opposite to the inner wall of the mounting chamber, and may cooperate with the inner wall of the mounting chamber to form the flow channel 300. Along its own air guiding direction, the end of the second air guide recess 542 extends to the end of the first air guide recess 541, and the ends of the second air guide recess 542 and the first air guide recess 541 are connected. That is, the downstream end of the second air guide recess 542 is formed at the outlet end of the atomizing channel 200, so that the outlet end of the flow channel 300 is connected to the outlet end of the atomizing channel 200. In this structure, the second air guide recess 542 is located on the outer surface of the air passage 540, which facilitates processing; therefore, this structure also facilitates the processing of the flow channel 300.

[0111] The second air guide recess 542 on the air duct component 540 cooperates with the inner wall of the mounting chamber of the bracket 510 to form a diversion channel 300. To ensure the sealing performance of the diversion channel 300, the air duct component 540 can be made of a material with sealing properties, such as silicone. In this way, both the air duct component 540 and the bracket 510 are made of materials with sealing properties, and the combined sealing performance is excellent, which can improve the sealing performance of the diversion channel 300. Optionally, the air duct component 540 can be directly snapped into the mounting chamber for mounting the air duct component 540, or the air duct component 540 can be connected to the bracket 510 with a separate snap-fit ​​structure. This application does not limit the specific connection method between the air duct component 540 and the bracket 510.

[0112] In another optional embodiment, the air passage 540 may have a second perforation, and the diversion channel 300 includes the second perforation. The inlet end of the diversion channel 300 (i.e., one port of the second perforation) may be formed on the outer wall surface of the air passage 540 that is not opposite to the atomizing core 520, for example, on the outer wall surface opposite to the atomizing core 520. Along its own air guiding direction, the downstream port of the second perforation may be formed at the outlet end of the atomizing channel 200. For example, the outlet end of the diversion channel 300 (i.e., the other port of the second perforation) may be formed on the inner wall of the first air guiding recess 541 that surrounds the outlet end of the atomizing channel 200, so that the outlet end of the diversion channel 300 is connected to the outlet end of the atomizing channel 200. In this case, the diversion channel 300 can extend in a straight line without bending or turning, reducing the energy loss of the airflow within the diversion channel 300.

[0113] Referring to Figures 19 to 22, the atomizing assembly 500 also includes a base 530. A portion of the base 530 can extend into the mounting chamber and seal its opening. The base 530 can be connected to the inner cavity of the oil cup 600 via snap-fit ​​or other means, completing the assembly of the bracket 510, atomizing coil 520, base 530, and airflow component 540. The base 530 may be equipped with an air inlet pipe 531, the cavity of which forms an air intake channel 400, which communicates with the external atmosphere.

[0114] The air passage component 540 may be provided with a receiving notch 543, into which at least a portion of the intake pipe 531 extends. A main air passage 700 is formed between the receiving notch 543 and the intake pipe 531. Both the atomizing channel 200 and the diverting channel 300 are connected to the intake channel 400 through the main air passage 700. The flow area of ​​the main air passage 700 may be larger than that of the diverting channel 300, so that after the gas in the intake channel 400 enters the main air passage 700, the gas in the main air passage 700 can be supplied to the atomizing channel 200 and the diverting channel 300.

[0115] For example, part of the opening of the accommodating notch 543 can be opposite to the inner wall of the bracket 510, and part of it can be opposite to the inner bottom surface of the base 530. The cross-sectional area of ​​the accommodating notch 543 (the area of ​​the cross section perpendicular to the airflow direction in the air intake channel 400) is larger than the cross-sectional area of ​​the air intake channel 400, so that the accommodating notch 543, the bracket 510, the base 530 and the air intake pipe 531 together form the main air passage 700.

[0116] There are various structures for connecting the atomizing channel 200 with the main air passage 700. In one optional embodiment, one end of the first air guide recess 541 can extend to the inner wall of the receiving notch 543 to connect the atomizing channel 200 with the main air passage 700. The diversion channel 300 can also be connected to the main air passage 700 by extending one end of the second air guide recess 542 to the inner wall of the receiving notch 543. That is, one end of the second air guide recess 542 can be formed on the inner wall of the receiving notch 543 to connect the diversion channel 300 with the main air passage 700.

[0117] In another alternative embodiment, referring to Figures 20 to 22, the inner bottom surface of the base 530 is provided with a support protrusion 532, the air passage 540 is supported on the support protrusion 532, and a liquid collection cavity is formed between the bottom surface of the air passage 540 and the inner bottom surface of the base 530. The inlet end of the first air guide recess 541 is opposite to the liquid collection cavity, and the receiving notch 543 includes an opening facing the liquid collection cavity so that the main air passage 700 communicates with the liquid collection cavity. The atomizing channel 200 communicates with the main air passage 700 through the liquid collection cavity.

[0118] This structure reduces the number of openings in the air passage 540 and improves the structural strength of the air passage 540. Furthermore, any leakage or condensation in the atomizing channel 200 can be collected in the collection chamber. The diversion channel 300 is connected to the collection chamber via the main air passage 700, allowing any leakage or condensation in the diversion channel 300 to be collected in the collection chamber.

[0119] Furthermore, since at least a portion of the air inlet pipe 531 extends into the receiving notch 543, the height difference between the port of the air inlet pipe 531 located inside the atomizer and the liquid collection chamber is increased, making it less likely for the liquid in the liquid collection chamber to leak out through the main air passage 700 and the air inlet channel 400, thereby improving the reliability of the atomizer.

[0120] Optionally, referring to Figure 20, the number of support protrusions 532 can be multiple, and the multiple support protrusions 532 are distributed at intervals to more stably support the airway component 540. The atomizer also includes two electrodes 800, which can pass through one support protrusion 532 respectively to achieve electrical connection with the atomizing core 520, making the internal structure of the atomizer more compact and facilitating the miniaturization design of the atomizer.

[0121] An adsorption component 550 can be installed on the inner bottom surface of the base 530. The height of the adsorption component 550 can be less than the height of the supporting protrusion 532, so that there is a gap between the bottom surface of the air passage component 540 and the adsorption component 550, allowing the main air passage 700 to communicate with the atomizing channel 200 through the gap. The adsorption component 550 is used to absorb leakage and condensate, mitigating the risk of leakage and condensate flowing outward through the liquid collection chamber, main air passage 700, and air intake channel 400 during atomizer use, further improving the reliability of the atomizer.
