Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomizing core, an atomizer, and an electronic atomization device. Background Technology

[0002] Electronic cigarettes and electronic devices used to atomize health care drugs, therapeutic drugs, and other substances can be collectively referred to as electronic atomization devices.

[0003] Electronic atomizing devices typically include an atomizer, which generally comprises a reservoir for storing e-liquid and an atomizing coil connected to the reservoir. The atomizing coil typically includes a guide fluid and a heating element connected to each other. When the electronic atomizer is operating, the e-liquid in the reservoir is guided by the guide fluid to the heating element. The heating element heats the e-liquid, producing an aerosol, which is then guided through the airway to the atomizer's outlet for the user to inhale. The heating element can be a metal heating wire, a metal heating plate, a conductive ceramic heating element, etc., and the guide fluid can be made of materials such as cotton or porous ceramic.

[0004] In related technologies, as the amount of atomizing liquid in the reservoir decreases and the amount of guiding liquid decreases, a negative pressure is formed. This negative pressure increases the resistance to subsequent atomizing liquid flowing into the guiding liquid. Therefore, to ensure smooth flow of subsequent atomizing liquid and allow the user to vape normally, air needs to be returned to the reservoir (i.e., outside air returns to the reservoir through the guiding liquid) to increase the air pressure inside the reservoir (i.e., reduce the negative pressure inside the reservoir). However, during the air return process, the gas guiding the liquid to the reservoir also needs to permeate into the reservoir through the guiding liquid. That is, the guiding path of the atomizing liquid into the guiding liquid and the return path of outside air returning to the reservoir through the guiding liquid are completely overlapping, and their flow directions are opposite. This causes the gas guiding the liquid to the reservoir to obstruct the flow of atomizing liquid into the guiding liquid. Therefore, when a user vapes for a long time in a single session, there is a problem that the atomizing liquid at the heating element location is difficult to replenish in time, resulting in dry burning. In severe cases, the heating element may burn out the guiding liquid. Summary of the Invention

[0005] This application provides an atomizing core, an atomizer, and an electronic atomizing device, which can increase the time of a single inhalation and reduce the risk of dry burning due to insufficient liquid in the delivery fluid.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide an atomizer, wherein the atomizer has an airway for delivering aerosol and a cavity communicating with the airway, the atomizer comprising:

[0007] The liquid storage chamber is provided with a receiving cavity for storing atomized liquid and an opening communicating with the receiving cavity;

[0008] A liquid guide, made of a porous material, is connected to the liquid storage tank and covers the opening. The liquid guide includes a first wall and a second wall facing away from the opening. The first wall is located on the flow path of the air passage, and the second wall is used to define the cavity.

[0009] A heating element is connected to the first wall surface. The heating element is used to heat the atomized liquid that permeates into the first wall surface through the opening to generate the aerosol.

[0010] In some embodiments, the first wall surface and the second wall surface are arranged at an angle, and the angle between the first wall surface and the second wall surface is an abscissa.

[0011] In some embodiments, the side of the liquid guide facing the opening is provided with a first groove capable of accommodating the atomized liquid.

[0013] The second wall surface is provided with a second groove, and the second groove has a third groove wall opposite to the second groove wall. The distance between the third groove wall and the second groove wall is L1, and the distance between the first groove wall and the first wall surface is L2, wherein L1 < L2.

[0016] In some embodiments, the heating element includes at least one of a metal heating element and a conductive ceramic heating element.

[0017] In some embodiments, the air passage includes an air inlet and an air outlet, the opening being located at the end of the liquid storage tank opposite to the air outlet.

[0018] In some embodiments, the airway further includes a first channel and a second channel communicating with the first channel;

[0019] The liquid storage tank includes an outer shell and an inner shell located inside the outer shell. The inner shell is provided with the first channel, and one end of the inner shell is provided with the air outlet located at the end of the first channel.

[0020] The liquid storage tank also includes a first base, which is located inside the outer shell and connected to the end of the inner shell away from the air outlet. The outer shell, the inner shell, and the first base together enclose the receiving cavity. The first base has the opening, the liquid guide is connected to the first base, and the first base has the second channel.

[0021] In some embodiments, the second channel is disposed at the center of the first base, and the opening is disposed off-center from the center of the first base.

[0022] In some embodiments, the airway further includes a third channel, and the atomizer further includes a second base, which is disposed inside the housing and on the side of the first base away from the air outlet. The second base is provided with the third channel, and the end of the second base away from the first base is provided with the air inlet located at the end of the third channel. The port of the third channel away from the air inlet is opposite to the first wall surface.

[0023] In some embodiments, the first base has an annular flange on the wall facing away from the air outlet. The annular flange is arranged around the opening and the second channel. The end of the annular flange facing away from the air outlet is connected to the second base, so that the liquid is disposed within the space enclosed by the first base and the second base.

[0024] In some embodiments, the second base has a first protrusion on the wall facing away from the air inlet, the third channel passes through the first protrusion, and the first protrusion, the annular flange, the wall of the first base facing the second base, the wall of the second base facing the first base, and the second wall together define the cavity.

[0025] In some embodiments, the first base has a second protrusion on the wall facing the second base, the second channel passes through the second protrusion, and the fluid guide is fixed between the second protrusion and the annular flange.

[0026] In some embodiments, the extension surfaces of the first wall and the second wall intersect at an interface line. The fluid guide further includes a third wall and a fourth wall facing away from the opening. The third wall is located on one side of the first wall and the second wall along a direction parallel to the interface line, and the fourth wall is located on the other side of the first wall and the second wall along a direction parallel to the interface line.

[0027] The heating element is attached to the first wall surface, and the atomizer further includes a first electrode and a second electrode. The first electrode is attached to the third wall surface and electrically connected to the end of the heating element near the third wall surface, and the second electrode is attached to the fourth wall surface and electrically connected to the end of the heating element near the fourth wall surface.

[0028] A second aspect of this application also provides an electronic atomizing device, comprising:

[0029] The atomizer described in any of the above embodiments; and

[0030] An energy storage component is electrically connected to the heating component and is used to supply power to the heating component.

[0031] A third aspect of this application also provides an atomizing core, which is applied to the atomizer described in any of the above embodiments, the atomizing core including the liquid guide and the heating element.

[0032] Compared with the prior art, the beneficial effects of this application are:

[0033] The atomizer provided in this application embodiment allows the atomized liquid in the receiving cavity to pass through the opening and permeate to the first wall surface of the liquid guide. The heating element heats the atomized liquid at the first wall surface to generate an aerosol for the user to inhale. After the atomized liquid flows out of the receiving cavity through the opening and into the liquid guide, a certain negative pressure is generated inside the receiving cavity. The air pressure inside the receiving cavity decreases as the amount of atomized liquid flowing out increases. At this time, gas near the second wall surface can pass through the second wall surface and permeate to the opening, thereby increasing the air pressure inside the receiving cavity. Since the first and second walls of the liquid guide are located at different positions, the atomized liquid in the receiving cavity reaches the first wall after passing through the opening (i.e., forming a liquid guide path from the opening to the first wall), while the gas near the second wall passes through the second wall and permeates to the opening before entering the receiving cavity (i.e., forming a return gas path from the second wall to the opening). In other words, the liquid guide path of the atomized liquid permeating from the opening to the first wall of the liquid guide and the return gas path of the gas near the second wall returning from the second wall to the receiving cavity are two independent paths. Therefore, the return gas flow inside the liquid guide will not obstruct the atomized liquid in the receiving cavity from reaching the first wall. Thus, when a user inhales for a long time in a single session, the gas can pass through the second wall and continuously permeate into the receiving cavity, allowing the gas pressure inside the receiving cavity to remain at a suitable level. This ensures a continuous supply of atomized liquid at the first wall position, extending the inhalation time of the atomizer and reducing the risk of damage due to prolonged dry burning of the liquid guide, thus extending the service life of the liquid guide and consequently the overall service life of the atomizer.

[0034] Furthermore, in the short period following the user's initial inhalation, the airflow velocity within the airway increases. While the volume of the cavity remains constant after the air is directed into the airway, the total gas volume decreases, creating a negative pressure within the cavity. This negative pressure hinders the flow of air from the cavity into the airway, making it difficult for the air in the cavity to follow the airflow within the airway. Consequently, the airflow velocity within the cavity is relatively slower than that within the airway. Based on the principle that higher flow velocity results in lower pressure, the air pressure within the cavity will be higher than the air pressure within the airway for a short period at the beginning of the user's inhalation. Since the second wall can be used to define the cavity and is located in the cavity, while the first wall is located on the airflow path of the airway, the pressure difference between the air pressure at the second wall and the air pressure at the opening will be greater than the pressure difference between the air pressure at the first wall and the air pressure at the opening. This makes it easier for the air in the cavity to pass through the second wall and penetrate into the receiving cavity, thereby making the return air in the receiving cavity smoother. This is beneficial to further extend the single inhalation time of the atomizer and further reduce the risk of liquid shortage and dry burning of the liquid guide. Attached Figure Description

[0068] See Figure 1-11This application provides an atomizer 10, which includes a liquid storage chamber 200, a liquid guide 110, and a heating element 123. In some embodiments, the atomizer 10 may further include an atomizing liquid 240. When the atomizer 10 includes an atomizing liquid 240, the atomizing liquid 240 may be stored in the receiving cavity 250 of the liquid storage chamber 200 of the atomizer 10. The atomizer 10 has an internal airway 300 that communicates with the outside and is used to deliver aerosol. The airway 300 includes an air inlet 331 and an air outlet 311 located at both ends of the airway 300 (illustratively, the air inlet 331 is located at the lower end of the airway 300, and the air outlet 311 is located at the upper end of the airway 300). When the user performs an inhalation action from the air outlet 311, outside air can enter the airway 300 through the air inlet 331 and carry the aerosol generated inside the airway 300 after the atomizing liquid 240 is atomized out of the airway 300 through the air outlet 311. In particular, in this embodiment, the atomizer 10 also has a cavity 500, which is located beside the airway 300 and communicates with the airway 300. The cavity 500 can be defined by one or more components of the atomizer 10. The specific structure of the cavity 500 is described in detail below.

[0069] See details Figure 1-3 The storage tank 200 has an internal receiving cavity 250 for containing the atomizing liquid 240. The storage tank 200 has an opening 231 that communicates with the receiving cavity 250, through which the atomizing liquid 240 can be discharged from the receiving cavity 250 and permeate into the guide liquid 110. When the amount of atomizing liquid 240 discharged from the receiving cavity 250 through the opening 231 is reduced, a certain negative pressure is generated in the receiving cavity 250. Under the action of this negative pressure, air outside the storage tank 200 can be drawn into the receiving cavity 250 through the opening 231 (i.e., return air), thereby increasing the air pressure in the receiving cavity 250 and reducing the resistance encountered by the atomizing liquid 240 when it is subsequently discharged from the receiving cavity 250.

[0070] The liquid guide 110 is connected to the liquid storage tank 200 and covers the opening 231 of the liquid storage tank 200. The atomized liquid 240 in the receiving cavity 250 can permeate into the liquid guide 110 through the opening 231 and thus exit the receiving cavity 250. The liquid guide 110 is made of a porous material. Specifically, the material of the liquid guide 110 can be porous ceramic, porous carbon fiber, porous quartz, diatomaceous earth, fiber cotton, porous polymer materials, etc., as long as it can meet the requirements of liquid guiding and gas return. This embodiment does not impose specific limitations on this. For ease of description, the following uses porous ceramic as the material of the liquid guide 110 as an example. It should be noted that the liquid guide 110 can be directly connected to the liquid storage tank 200 or indirectly connected to the liquid storage tank 200. When the liquid guide 110 is indirectly connected to the liquid storage tank 200, a sealing sleeve 600 can be installed outside the liquid guide 110. The sealing sleeve 600 is connected to the liquid storage tank 200 and has an opening (not shown in the figure) communicating with the opening 231 on the liquid storage tank 200. After the liquid guide 110 is placed inside the sealing sleeve 600, the liquid guide 110 covers the opening on the sealing sleeve 600, thereby indirectly covering the opening 231 on the liquid storage tank 200. The atomizing liquid 240 in the receiving cavity 250 passes through the opening 231 on the liquid storage tank 200 and the opening on the sealing sleeve 600 in sequence and then permeates into the liquid guide 110.

[0071] The liquid guide 110 has a first wall 111 and a second wall 112 arranged in a direction opposite to the opening 231. The first wall 111 is located on the flow path of the airway 300. When the user performs suction, the airflow entering the airway 300 through the air inlet 331 flows through the first wall 111 and is finally exited from the air outlet 311. The atomized liquid 240 in the receiving cavity 250 can permeate from the opening 231 to the position of the first wall 111 of the liquid guide 110. Furthermore, the second wall 112 is used to define the cavity 500. In other words, the second wall 112 is one of the walls enclosing the cavity 500, and the air in the cavity 500 can directly pass through the second wall 112 and permeate into the liquid guide 110.

[0072] The heating component 123 is a component that can generate heat and heat the atomized liquid 240 after being powered on. Specifically, the heating component 123 can be at least one of a metal heating element (such as a metal heating wire, a metal heating plate, etc.) or a conductive ceramic heating element. It is only necessary to be able to atomize the atomized liquid that has penetrated into the first wall surface 111 into an aerosol. This embodiment does not impose any specific restrictions on this. Heating component 123 is connected to the first wall surface 111 of the liquid guide 110. When the atomized liquid 240 in the receiving cavity 250 permeates through the opening 231 to the first wall surface 111 of the liquid guide 110, heating component 123 can heat the atomized liquid 240 that has permeated to the first wall surface 111, thereby atomizing the atomized liquid 240 and generating an aerosol that can be inhaled by the user. When the user inhales, the airflow formed in the airway flows through the first wall surface 111 and carries away the aerosol generated at the first wall surface 111. The aerosol follows the airflow in the airway 300 and is finally discharged from the airway 300 through the air outlet 311 and inhaled by the user. When the atomized liquid 240 at the first wall surface 111 is consumed, subsequent atomized liquid 240 continuously permeates to the first wall surface 111 to replenish it, thereby forming a continuous liquid guide path a from the opening 231 to the first wall surface 111.

[0073] The atomizer 10 provided in this embodiment allows the atomizing liquid 240 in the receiving cavity 250 to pass through the opening 231 and permeate to the first wall 111 of the guiding liquid 110. The heating element 123 heats the atomizing liquid 240 at the first wall 111 to generate an aerosol for the user to inhale. After the atomizing liquid 240 flows out of the receiving cavity 250 through the opening 231 and into the guiding liquid 110, a certain negative pressure is generated inside the receiving cavity 250. The air pressure inside the receiving cavity 250 decreases as the amount of atomizing liquid 240 flowing out increases. At this time, gas near the second wall 112 can pass through the second wall 112 and permeate to the opening 231, thereby increasing the air pressure inside the receiving cavity 250. Since the first wall 111 and the second wall 112 of the liquid guide 110 are two walls in different positions, the atomized liquid 240 in the receiving cavity 250 passes through the opening 231 and reaches the first wall 111 (i.e., forming a liquid guide path a from the opening 231 to the first wall 111). The gas near the second wall 112 passes through the second wall 112 and permeates to the opening 231 before being introduced into the receiving cavity 250 (i.e., forming a return gas path b from the second wall 112 to the opening 231). In other words, the liquid guide path a from the opening 231 to the first wall 111 of the liquid guide 110 and the return gas path b from the second wall 112 back to the receiving cavity 250 are two independent and different paths. Therefore, the return gas flow inside the liquid guide 110 will not obstruct the atomized liquid 240 in the receiving cavity 250 from being guided to the first wall 111. Therefore, when a user inhales for a long time in a single session, the gas can pass through the second wall 112 and continuously permeate into the receiving cavity 250, so that the air pressure in the receiving cavity 250 can remain at a suitable level. This ensures a continuous supply of atomizing liquid 240 at the position of the first wall 111. On the one hand, this can extend the duration of a single inhalation of the atomizer 10, and on the other hand, it reduces the risk of damage caused by prolonged dry burning due to lack of liquid in the liquid guide 110, thereby improving the service life of the liquid guide 110 and thus improving the overall service life of the atomizer 10.

[0074] Furthermore, in the short period after the user begins inhaling, the airflow velocity within airway 300 increases. After the air in cavity 500 is guided into airway 300, the volume of cavity 500 remains unchanged, and the total amount of gas in cavity 500 decreases. Therefore, a certain negative pressure will be generated in cavity 500. This negative pressure will hinder the air in cavity 500 from being guided into airway. Consequently, the air in cavity 500 is difficult to flow with the air in airway 300, and the airflow velocity in cavity 500 is relatively slower than that in airway 300. According to the principle that the faster the flow velocity, the lower the pressure, in the short period after the user begins inhaling, the air pressure in cavity 500 will be greater than the air pressure in airway 300. Since the second wall 112 is located in the cavity 500, while the first wall 111 is located on the airflow path of the airway, the pressure difference between the air pressure at the second wall 112 and the air pressure at the opening 231 is greater than the pressure difference between the air pressure in the airway 300 and the air pressure at the opening 231. This makes it easier for the air in the cavity 500 to pass through the second wall 112 and penetrate into the receiving cavity 250, thereby making the return air in the receiving cavity 250 smoother. This is beneficial for further extending the single inhalation time of the atomizer 10 and for further reducing the risk of dry burning due to lack of liquid in the liquid guide 110.

[0075] The specific structure and relative position of the first wall 111 and the second wall 112 depend on actual needs. Both the first wall 111 and the second wall 112 can be planar walls; both can also be curved walls. The first wall 111 and the second wall 112 can be arranged adjacent to each other; other walls can also be provided between the first wall 111 and the second wall 112, for example, the first wall 111 and the second wall 112 can be arranged opposite each other. For ease of description, the following description uses the example of the first wall 111 and the second wall 112 being both planar and arranged adjacent to each other. When the first wall 111 and the second wall 112 are arranged adjacent to each other, they can be located on the same plane or intersect each other. In some embodiments, see... Figure 2 as well as Figure 10 The angle between the first wall 111 and the second wall 112 is an abscissa; in other words... Figure 10 The included angle α is greater than 180° and less than 360°. Preferably, α can be between 200° and 300°. For example, α can be 200°, 220°, 240°, 260°, 280°, or 300°, etc. When both the first wall surface 111 and the second wall surface 112 are curved walls, see [reference needed]. Figure 11If there exists an angle between the first plane 700 and the second plane 800 that is greater than 180° and less than 360° (i.e., angle β is greater than 180° and less than 360°), then the angle between the first wall 111 and the second wall 112 is considered to be an anomalous angle (the first wall 111 and the second wall 112, which are curved surfaces, are mutually opposite). Here, the first plane 700 is any one of the external tangents of the first wall 111, and the second plane 800 is any one of the external tangents of the second wall 112.

[0076] When the angle between the first wall 111 and the second wall 112 is greater than 180 degrees and less than 360 degrees, the air near the first wall 111 and the air near the second wall 112 are in a state of mutual separation. Therefore, the interference of the hot airflow at the first wall 111 on the air at the second wall 112 can be reduced. The air at the second wall 112 can more easily pass through the second wall 112 and penetrate to the opening 231, thereby making the return air of the receiving cavity 250 smoother and further extending the single suction time of the atomizer 10. Furthermore, when the atomizing liquid 240 at the first wall surface 111 is heated and atomized, the aerosol generated by the atomization of the atomizing liquid 240 at the first wall surface 111 is difficult to flow from the inside of the guide liquid 110 to the second wall surface 112 and thus hinder the gas transmission at the second wall surface 112. Therefore, the return gas flow at the second wall surface 112 can be improved, which not only helps to further extend the single suction time of the atomizer 10, but also helps to further reduce the risk of damage caused by prolonged dry burning due to lack of liquid in the guide liquid 110.

[0077] To facilitate the penetration of the atomizing liquid 240 into the interior of the guiding liquid 110, in some embodiments, see [reference needed]. Figure 2-3 The liquid guide 110 has a first groove 115 on the side facing the opening 231, which can accommodate the atomized liquid 240. On the one hand, the first groove 115 allows the atomized liquid 240 in the receiving cavity 250 to pass through the opening 231 and be stored in the first groove 115. On the other hand, the first groove 115 can also reduce the path length of the atomized liquid in the receiving cavity 250 through the liquid guide 110 to the first wall 111, and reduce the path length of the air at the second wall 112 through the liquid guide 110 to the receiving cavity 250, thereby further improving the smoothness of liquid supply and air return in the receiving cavity 250.

[0078] When a user inhales, the air outlet 311 of the atomizer 10 is located above the atomizer 10. At this time, the direction of gravity acting on the atomized liquid 240 in the receiving cavity 250 is generally opposite to the direction of the air outlet 311. To facilitate the flow of the atomized liquid 240 in the receiving cavity 250 to the guide liquid 110 under the influence of gravity when the user inhales, in some embodiments, the opening 231 of the liquid storage chamber 200 is located at the end of the receiving cavity 250 opposite to the opening 231. This ensures that when the user inhales, the guide liquid 110 is located below all the atomized liquid 240, maximizing the pressure of the atomized liquid 240 on the guide liquid 110. This increases the force of the atomized liquid 240 penetrating into the guide liquid 110, improving the smoothness of the atomized liquid 240 exiting the liquid storage chamber 200. Simultaneously, when the atomized liquid 240 is about to be consumed, the remaining small amount of atomized liquid 240 can also be easily discharged from the opening 231.

[0079] In some embodiments, see Figure 2-3 The bottom wall of the first groove 115 opposite to the opening 231 includes a first groove wall 1151 and a second groove wall 1152. The first groove wall 1151 is arranged opposite to the first wall surface 111, and the second groove wall 1152 is arranged opposite to the second wall surface 112, with an acute angle between them. Further, the first groove wall 1151 can be arranged parallel to the first wall surface 111, and the second groove wall 1152 can be arranged parallel to the second wall surface 112. The acute angle between the first groove wall 1151 and the second groove wall 1152 makes it easier for the atomizing liquid 240 to be stored in the narrow space at the junction of the first groove wall 1151 and the second groove wall 1152 when the residual amount of atomizing liquid 240 is low, thus improving the utilization efficiency of the atomizing liquid 240.

[0080] In some embodiments, see Figure 2 as well as Figure 10 The second wall surface 112 is provided with a second groove 116, and the second groove 116 has a third groove wall 1161 opposite to the second groove wall 1152. The distance between the third groove wall 1161 and the second groove wall 1152 is L1, and the distance between the first groove wall 1151 and the first wall surface 111 is L2, where L1 < L2. In other words, the wall thickness of the liquid guide 110 at the bottom wall of the first groove 115 (i.e., L1) is less than the wall thickness of the liquid guide 110 at the first wall surface 111 (i.e., L2). This design allows the air at the cavity 500 to more easily permeate from the third groove wall 1161 of the first groove 115 to the second groove wall 1152, and finally pass through the first groove 115 and the opening 231 of the liquid storage tank 200 to enter the receiving cavity 250 of the liquid storage tank 200, thus shortening the return air path and making the return air in the receiving cavity 250 more unobstructed.

[0081] To further improve the air return flow of the accommodating cavity 250, in some embodiments, a plurality of second grooves 116 are formed on the second wall surface 112. Furthermore, the second grooves 116 are arranged in a straight line.

[0082] See Figure 1 as well as Figure 3 In some embodiments, the airway 300 includes a first channel 310, a second channel 320 and a third channel 330 that are connected to each other. The first channel 310, the second channel 320 and the third channel 330 are each provided by different components. The specific arrangement of the first channel 310, the second channel 320 and the third channel 330 is detailed below.

[0083] The liquid storage tank 200 includes an outer shell 210 and an inner shell 220 located within the outer shell 210. The inner shell 220 has the aforementioned first channel 310 inside, and one end of the inner shell 220 has an outlet 311 for discharging aerosol into the user's mouth during inhalation; that is, the outlet 311 is located at the end of the first channel 310. The liquid storage tank 200 also includes a first base 230, located within the outer shell 210, and connected to the end of the inner shell 220 opposite to the outlet 311. The outer shell 210, inner shell 220, and first base 230 enclose a receiving cavity 250 for containing the atomizing liquid 240. The first base 230 is provided with the aforementioned opening 231, and the liquid guide 110 is connected to the first base 230. The first base 230 is provided with the aforementioned second channel 320, and one end of the second channel 320 facing away from the air inlet 331 is connected to the end of the first channel 310 facing away from the air outlet 311. In this solution, the opening 231 is provided on the first base 230, which is located at the end of the receiving cavity 250 facing away from the air outlet 311. The opening 231 can be processed when the first base 230 is not assembled into the outer shell 210 and the inner shell 220, making the processing of the opening 231 easier. At the same time, the arrangement of the opening 231 also achieves the purpose of setting the opening 231 at the end of the receiving cavity 250 facing away from the air outlet 311, making it easier for the atomized liquid 240 in the receiving cavity 250 to be discharged from the opening 231.

[0084] In some embodiments, the second channel 320 is disposed at the center of the first base 230, and the opening 231 is disposed off-center from the center of the first base 230. In this arrangement, the second channel 320 can easily communicate with the first channel 310 along a straight line. The structural arrangement of the second channel 320 is relatively simple. Compared with the arrangement where the second channel 320 is disposed off-center, there is no need to additionally calibrate the relative position of the second channel 320 and the first channel 310 during the assembly of the first base 230, thus reducing the assembly difficulty of the first base 230.

[0085] In some embodiments, the atomizer 10 further includes a second base 400, which is disposed within the housing 210 and located on the side of the first base 230 opposite to the air outlet 311. Specifically, in this embodiment, the second base 400 is located at the end of the housing 210 opposite to the air outlet 311. The second base 400 is provided with the aforementioned third channel 330, and an air inlet 331 is provided at the end of the second base 400 opposite to the first base 230. The port of the third channel 330 opposite to the air inlet 331 is opposite to the first wall surface 111. After the airflow enters the third channel 330 through the air inlet 331, it is guided to the first wall surface 111 through the port of the third channel 330 opposite to the air inlet 331. The heating element 123 at the first wall surface 111 heats the atomizing liquid 240 at the first wall surface 111 to generate an aerosol for the user to inhale. The aerosol at the first wall surface 111 enters the second channel 320 through the port opposite to the air outlet 311, and then enters the first channel 310 through the connection between the second channel 320 and the first channel 310. The aerosol is finally discharged from the air outlet 311 of the first channel 310 into the airway 300 for the user to inhale. Understandably, in this embodiment, the airway 300 can be defined by the first base 230, the second base 400, the first wall surface 111, and the inner shell 220.

[0086] See Figure 2-3 The first base 230 has an annular flange 233 on its wall facing away from the air outlet 311. The annular flange 233 surrounds the opening 231 and the second channel 320. The end of the annular flange 233 facing away from the air outlet 311 is connected to the second base 400. The annular flange 233 can be closed or open. When the annular flange 233 is closed, the liquid guide 110 is located within the space enclosed by the first base 230 and the second base 400. When the annular flange 233 is open, the liquid guide 110 is located within the space enclosed by the wall of the first base 230 facing the second base 400, the wall of the second base 400 facing the first base 230, the inner wall of the annular flange 233, and the inner wall of the outer shell 210. The annular flange 233 can limit the distance between the first base 230 and the second base 400, thereby facilitating the positioning of the second base 400. When the second base 400 abuts against the annular flange 233 during the assembly process, the second base 400 is in the corresponding assembly position, which facilitates the assembly of the second base 400.

[0087] In some embodiments, the second base 400 has a first protrusion 410 on the wall facing away from the air inlet 331, and a third channel 330 passes through the first protrusion 410. The first protrusion 410, the annular flange 233, the second wall surface 112, the wall surface of the first base 230 facing the second base 400, and the wall surface of the second base 400 facing the first base 230 together define a cavity 500. That is, the cavity 500 is annular and surrounds the first protrusion 410. The cavity 500 is connected to the second channel 320 and the third channel 330 at the same position, and the first wall surface 111 is located between the connection positions of the second channel 320 and the third channel 330. The cavity 500 communicates with the air passage 300 through the port of the third channel 330 in the first protrusion 410 facing the first wall surface 111.

[0088] In other embodiments, the cavity 500 can be defined in other ways. For example, in some embodiments, the cavity 500 can be defined only by the second base 400 and the second wall surface 112. Specifically, the side wall of the second base 400 facing the first base 230 can be provided with a recess, and after the second base 400 is assembled, the second wall surface 112 closes and covers part of the cavity opening, and the cavity is only connected to the air passage 300. The internal space of the cavity is the aforementioned cavity 500. In other embodiments, the cavity 500 can also be defined only by the first base 230 and the second wall surface 112. Specifically, the first base 230 is provided with a recess. When the liquid guide 110 is assembled on the first base 230, the second wall surface 112 of the liquid guide 110 covers part of the cavity opening, and the cavity is only connected to the air passage 300. The internal space of the cavity is the aforementioned cavity 500. In some other embodiments, the cavity 500 may also be enclosed solely by the outer shell 210 and the second wall 112. Specifically, the outer shell 210 has a recessed cavity inside. When the liquid guide 110 is assembled onto the first base 230, the second wall 112 of the liquid guide 110 covers part of the cavity opening and makes the cavity communicate only with the air passage 300. The internal space of the cavity is the aforementioned cavity 500.

[0089] See Figure 2-5In some embodiments, the first base 230 has a second protrusion 232 on the wall facing the second base 400, and the second channel 320 passes through the second protrusion 232. The liquid guide 110 is fixed between the second protrusion 232 and the annular flange 233. In this scheme, the liquid guide 110 is fixed by the gap between the second protrusion 232 and the annular flange 233, so that both ends of the liquid guide 110 are supported, and the installation of the liquid guide 110 is more stable. The liquid guide 110 can be directly connected and fixed to the second protrusion and the annular flange 233, or it can be indirectly connected and fixed to the second protrusion and the annular flange 233. When the liquid guide 110 is indirectly connected to the annular flange 233 and the second protrusion, the atomizer 10 also includes a sealing sleeve 600, which is annular and is fitted around the outer periphery of the liquid guide 110. The outer peripheral wall of the sealing sleeve 600 is connected to the annular flange 233 and the second protrusion, and the inner peripheral wall of the sealing sleeve 600 is connected to the liquid guide 110, thereby achieving a seal between the outer periphery of the liquid guide 110 and the annular flange 233 and the second protrusion. Furthermore, the end of the sealing sleeve 600 facing the opening 231 can extend inward and connect to the wall surface of the liquid guide 110 with the first groove 115, thereby sealing the gap between the liquid guide 110 and the wall surface of the first base 230 away from the receiving cavity 250. In this case, the liquid guide 110 and the wall surface of the first base 230 away from the receiving cavity 250 are indirectly connected through the sealing sleeve 600.

[0090] See Figure 2 , 3 8 and Figure 10In some embodiments, the extended surface of the first wall 111 and the extended surface of the second wall 112 intersect at an intersection line 117. The liquid guide 110 also includes a third wall 113 and a fourth wall 114 away from the outlet 231. The third wall 113 is located on one side of the first wall 111 and the second wall 112 parallel to the intersection line 117, and the fourth wall 114 is located on the other side of the first wall 111 and the second wall 112 parallel to the intersection line 117. The heating element 123 is attached to the first wall 111. The atomizer 10 also includes a first electrode 121 and a second electrode 122. The first electrode 121 is attached to the third wall 113 and electrically connected to the end of the heating element 123 near the third wall 113, and the second electrode 122 is attached to the fourth wall 114 and electrically connected to the end of the heating element 123 near the fourth wall 114. In this design, the first electrode 121 is disposed on the third wall surface 113 and the second electrode 122 is disposed on the fourth wall surface 114. Neither the first electrode 121 nor the second electrode 122 is disposed on the first wall surface 111, so that the area on the first wall surface 111 can be maximized. The space on the first wall surface 111 is larger, which facilitates the installation of the heating element and increases the heating area, thereby improving the overall atomization effect of the atomizer 10.

[0091] Correspondingly, this application embodiment also provides an electronic atomizing device, which includes the atomizer 10 in any of the above embodiments. The electronic atomizing device also includes an energy storage component, which is electrically connected to the heating component 123 and is used to provide current to the heating component 123 so that the heating component 123 can generate heat after the current is applied and heat the atomized liquid 240 conducted to the first wall surface 111. In some specific application scenarios, the energy storage component of this embodiment can be a power source such as a lithium battery. In addition, the electronic atomizing device of this embodiment may also include a control circuit board, which is electrically connected to the energy storage component and the heating component 123 respectively. In use, the control circuit board can control the energy storage component to supply power to the heating component 123, so that the heating component 123 is energized and heats up, atomizing the atomized liquid conducted to the first wall surface 111 into an aerosol that can be inhaled by the user.

[0092] Correspondingly, see Figure 1-11 This application also provides an atomizing core 100, which is applied to the atomizer 10 in any of the above embodiments.
