Description

Technical Field

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

[0002] Electronic atomizing devices, which use heated atomizing coils to convert a liquid matrix into an aerosol for inhalation, have rapidly gained popularity in recent years. The performance of their core component—the atomizer—directly determines the overall performance and user satisfaction of the electronic atomizing device.

[0003] However, the atomizers in existing electronic atomizing devices are not perfect in design, and often cause coil clogging due to insufficient liquid supply rate to the atomizing coil. Utility Model Content

[0004] This application provides an electronic atomizing device and its atomizer to solve the problem of coil clogging caused by insufficient liquid supply rate to the atomizing coil in the atomizer.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: providing an atomizer. The atomizer includes: a housing assembly, within which a first cavity and a second cavity are formed in communication; an atomizing component, assembled in the second cavity, including a shell and an atomizing core, the atomizing core being installed in the shell, a liquid supply chamber surrounding the atomizing core being formed within the shell, a liquid passage hole at the top of the shell connecting the first cavity and the liquid supply chamber, and the ratio of the volume of the first cavity to the volume of the liquid supply chamber being 3 to 10.

[0006] In some embodiments, the first cavity is disposed around the second cavity, the liquid passage is connected to the second cavity, and the liquid stored in the first cavity flows to the liquid supply cavity through the second cavity.

[0007] In some embodiments, the volume of the liquid supply chamber is 1 to 3 ml, and the volume of liquid that can be stored in the second cavity is less than or equal to the volume of the liquid supply chamber.

[0008] In some embodiments, the second cavity and the first cavity are separated by a tube, and the tube is provided with a communicating hole connecting the first cavity and the second cavity;

[0009] A conical surface is formed on the end face of the second cavity facing the outer shell. When the atomizer is inverted, the conical surface allows the liquid in the second cavity to flow back to the first cavity through the connecting hole.

[0010] In some embodiments, the housing assembly further includes a movable member movably disposed within the second cavity, the movable member having the tapered surface at one end facing the atomizing assembly, the atomizing core extending from one end of the housing and connected to the movable member, and the housing being movably assembled within the second cavity;

[0011] Wherein, when the atomizing component is assembled into the second cavity, the movable component avoids the connecting hole, so that the connecting hole connects the first cavity and the second cavity; when the atomizing component is disassembled from the second cavity, the movable component blocks the connecting hole.

[0012] In some embodiments, the movable component includes a movable cylinder and a tapered end connected to one end of the movable cylinder. The movable cylinder is movably assembled with the inner wall surface of the second cavity. The outer surface of the tapered end facing the outer shell is the tapered surface. A liquid collecting groove is formed on the inner surface of the tapered end. A liquid collecting element is provided inside the movable cylinder and on the liquid collecting groove. The liquid collecting element has an atomization channel communicating with the atomization channel of the atomizing core.

[0013] In some embodiments, the atomizing core includes an atomizing sleeve, a liquid-absorbing element, and a heating element. The atomizing sleeve has a liquid inlet on its side wall. The liquid-absorbing element is disposed inside the atomizing sleeve and covers the liquid inlet. The heating element is stacked on the side of the liquid-absorbing element away from the liquid inlet.

[0014] The atomizing sleeve includes a first sleeve and a second sleeve. The second sleeve is sleeved inside the first sleeve and is interference-fitted with it. The first sleeve is provided with a first liquid inlet, and the second sleeve is provided with a second liquid inlet. The first liquid inlet and the second liquid inlet are stacked to form the liquid inlet. An air exchange groove communicating with the second liquid inlet is opened on the tube wall of the second sleeve.

[0015] The inner wall of the first sleeve and the outer side of the liquid suction element respectively cover the inner and outer sides of the ventilation groove, and together with the ventilation groove, they form a ventilation channel, which connects the atmosphere and the second liquid inlet.

[0016] In some embodiments, the heating element includes an upper heating mesh and a lower heating mesh distributed and connected along the axial direction of the atomizing sleeve. The second sleeve has two second liquid inlets spaced apart along the axial direction, corresponding to the upper heating mesh and the lower heating mesh respectively. The ventilation groove is connected to the second liquid inlet corresponding to the upper heating mesh.

[0017] In some embodiments, the dimension of the first inlet along the circumference of the first sleeve is smaller than the dimension of the second inlet along the circumference of the second sleeve.

[0018] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an electronic atomizing device. The electronic atomizing device includes a main unit and an atomizer as described above, wherein the main unit is connected to the atomizer and supplies power to the atomizer.

[0019] The beneficial effects of this application are as follows: Unlike the prior art, this application discloses an electronic atomizing device and its atomizer. In this application, the liquid supply chamber surrounding the atomizing core is an empty cavity without a liquid storage cotton. Therefore, the atomizing core can directly contact the aerosol matrix. By eliminating the liquid storage cotton, the obstruction of the liquid storage cotton to the conduction of the aerosol matrix is ​​eliminated, and the aerosol matrix enters the atomizing core faster, avoiding the phenomenon of core clogging due to untimely aerosol supply. Furthermore, the ratio of the volume of the first cavity to the volume of the liquid supply chamber is 3 to 10, which allows the liquid supply chamber to store an appropriate amount of aerosol matrix, thus reducing the risk of leakage and ensuring sufficient and timely liquid supply to the atomizing core, preventing the atomizing core from dry burning. At the same time, it also eliminates the adsorption of fragrance and flavor substances of the aerosol matrix by the liquid storage cotton, increasing the original flavor reduction of the aerosol.

[0031] This application provides an electronic atomizing device 300, see reference. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application.

[0032] The electronic atomizing device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0033] The electronic atomizing device 300 can be used to atomize aerosol matrices such as e-liquid, medicinal liquid, or nutrient solution, that is, to atomize liquid aerosol matrices into aerosols for users to inhale. The main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, thus allowing the atomizer 100 to be replaced; alternatively, the main unit 200 and the atomizer 100 can be integrated into one unit and supply power to the atomizer 100. The atomizer 100 stores and atomizes the aerosol matrix to form an aerosol for the user to inhale.

[0034] The main unit 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect to the atomizer 100 to identify the status information of the atomizer 100 and control the power supply to the atomizer 100 based on the identified status information.

[0035] Please refer to the following: Figures 2 to 4 , Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the atomizer in the electronic atomizing device. Figure 3 yes Figure 2 The diagram shows the atomizer in its separated state, with the housing assembly and atomizing assembly in between. Figure 4 yes Figure 2 The diagram shows the structure of the atomizing component in the atomizer.

[0036] like Figure 2 and Figure 4 As shown, the atomizer 100 includes a housing assembly 10 and an atomizing assembly 2. The housing assembly 10 has a first cavity 101 and a second cavity 102 that are connected to each other. The first cavity 101 is used to store the aerosol matrix. The atomizing assembly 2 is assembled in the second cavity 102 and includes a shell 20 and an atomizing core 40. The atomizing core 40 is installed in the shell 20. A liquid supply chamber 205 is formed in the shell 20 surrounding the atomizing core 40. The liquid inlet 401 on the side wall of the atomizing core 40 is connected to the liquid supply chamber 205. The top of the shell 20 is provided with a liquid passage hole 201, which connects the first cavity 101 and the liquid supply chamber 205. The ratio of the volume of the first cavity 101 to the volume of the liquid supply chamber 205 is 3 to 10.

[0037] The aerosol matrix in the first cavity 101 supplies liquid to the liquid supply cavity 205, and the liquid inlet 401 of the atomizing core 40 is located in the liquid supply cavity 205, and the aerosol matrix in the liquid supply cavity 205 supplies liquid to the atomizing core 40.

[0038] The ratio of the volume of the first chamber 101 to the volume of the liquid supply chamber 205 can be 3, 4, 5, 6, 7, 8, 9, or 10. If the ratio is less than 3, the liquid supply chamber 205 will store too much aerosol matrix, drastically increasing the risk of leakage through the atomizing core 40 and its connections, making leakage accidents more likely. If the ratio is greater than 10, the liquid supply chamber 205 will store too little aerosol matrix, resulting in insufficient supply to the atomizing core 40 and potentially causing dry burning. Therefore, a ratio between 3 and 10 balances the risk of leakage while ensuring a sufficient and timely liquid supply to the atomizing core 40, preventing dry burning.

[0039] In this embodiment, the liquid supply chamber 205 surrounding the atomizing core 40 is an empty cavity without a liquid storage cotton inside. Therefore, the atomizing core 40 inside can directly contact the aerosol matrix. Since the liquid storage cotton is eliminated, the obstruction of the liquid storage cotton to the conduction of the aerosol matrix is ​​relatively eliminated, and the aerosol matrix enters the atomizing core 40 at a faster speed, avoiding the phenomenon of core clogging due to untimely aerosol supply. Furthermore, the ratio of the volume of the first cavity 101 to the volume of the liquid supply chamber 205 is 3 to 10, which allows the liquid supply chamber 205 to store an appropriate amount of aerosol matrix, which can balance reducing the risk of leakage and ensuring sufficient and timely liquid supply to the atomizing core 40, and preventing the atomizing core 40 from dry burning.

[0040] Furthermore, the volume of the liquid supply chamber 205 is 1 to 3 ml, specifically 1 ml, 2 ml or 3 ml. This range of liquid volume can take into account both reducing the risk of leakage and ensuring sufficient and timely liquid supply to the atomizing core 40, thus preventing the atomizing core 40 from burning dry.

[0041] In the housing assembly 10, the first cavity 101 is used to store the aerosol matrix, and the second cavity 102 is used to assemble the atomizing assembly 2. The first cavity 101 may be arranged around the second cavity 102, or the first cavity 101 and the second cavity 102 may be arranged side by side.

[0042] In this embodiment, the first cavity 101 is arranged around the second cavity 102, and the second cavity 102 and the first cavity 101 are separated by a tube 104. The tube 104 is provided with a connecting hole 103 connecting the first cavity 101 and the second cavity 102. The liquid stored in the first cavity 101 flows to the liquid supply cavity 205 through the second cavity 102.

[0043] Specifically, see Figure 3The housing assembly 10 includes a housing 12 and a base 14. One end of the housing 12 has a suction nozzle 120, and the other end is an open end. The base 14 includes a seat 140 and a tube 104 connected to the seat 140. The cavity connected to the seat 140 and the tube 104 together form a second cavity 102. The seat 140 is sealed to the open end of the housing 12, and the end of the tube 104 away from the seat 140 is sealed to the suction nozzle 120.

[0044] Optionally, the first cavity 101 and the second cavity 102 can be arranged side by side. For example, the space inside the housing 12 is separated by a partition to form the first cavity 101 and the second cavity 102. The partition is provided with a connecting hole 103 that connects the first cavity 101 and the second cavity 102.

[0045] The atomizing component 2 is detachably installed in the second cavity 102, for example, the atomizing component 2 can be plugged in, snapped in or screwed into the second cavity 102.

[0046] In this embodiment, the atomizing component 2 is movably embedded in the second cavity 102 so as to facilitate the installation and removal of the atomizing component 2 from the housing assembly 10.

[0047] Optionally, the liquid passage hole 201 on the outer shell 20 can be directly connected to the connecting hole 103, that is, the aerosol matrix in the first cavity 101 can be directly supplied to the space inside the outer shell 20. For example, the inner side of the tube 104 is formed with a slope, and the connecting hole 103 is a hole on the slope. The top of the outer shell 20 also forms a corresponding slope and is attached to the slope on the inner side of the tube 104. The liquid passage hole 201 is also connected to the connecting hole 103.

[0048] In this embodiment, as Figure 2 As shown, after the atomizing component 2 is embedded in the second cavity 102, the second cavity 102 is not completely occupied, leaving a portion of the space as a transition cavity 106 to connect the first cavity 101 with the liquid passage 201 of the outer shell 20. That is, both the connecting hole 103 and the liquid passage 201 are connected to the transition cavity 106, which is part of the second cavity 102. The aerosol matrix in the first cavity 101 enters the liquid supply cavity 205 in the outer shell 20 through the connecting hole 103, the transition cavity 106, and the liquid passage 201.

[0049] In this case, the volume of liquid storage in the second cavity 102 is less than or equal to the volume of the liquid supply cavity 206, that is, the volume of the transition cavity 106 is less than or equal to the volume of the liquid supply cavity 206. Thus, the transition cavity 106 can increase the aerosol buffer capacity of the liquid supply cavity 206 and reduce the pressure of the aerosol matrix of the liquid supply cavity 205 on the atomizing core 40, thereby reducing the risk of leakage of the atomizing core 40.

[0050] Furthermore, a conical surface 105 is formed on the end face of the second cavity 102 facing the outer shell 20. When the atomizer 100 is inverted, the conical surface 105 allows the liquid in the second cavity 102 to flow back to the first cavity 101 through the connecting hole 103. Therefore, when the atomizer 100 is inverted to replace the atomizing component 2, the liquid stored in the transition cavity 106 can avoid leakage by flowing back to the first cavity 101, thus reducing the risk of leakage.

[0051] like Figure 2 and Figure 3 As shown, the housing assembly 10 also includes a movable member 16 movably disposed within the second cavity 102. The movable member 16 has a conical surface 105 at one end facing the atomizing assembly 2. The atomizing core 40 extends from one end of the housing 20 and is connected to the movable member 16. The housing 20 is movably assembled within the second cavity 102. (See also...) Figure 2 In this configuration, when the atomizing assembly 2 is assembled into the second cavity 102, the movable component 16 avoids the connecting hole 103, allowing the connecting hole 103 to connect the first cavity 101 and the second cavity 102; please refer to [link to relevant documentation]. Figure 3 After the atomizing assembly 2 is removed from the second cavity 102, the movable part 16 blocks the connecting hole 103.

[0052] The second cavity 102 is a cylindrical cavity. The user can simultaneously drive the movement of the movable part 16 by installing the atomizing component 2 into the second cavity 102 and removing the atomizing component 2 from the second cavity 102. The movable part 16 can move to the first position to avoid the connecting hole 103. The movable part 16 can move to the second position to block the connecting hole 103 and prevent the aerosol matrix in the first cavity 101 from leaking from the connecting hole 103.

[0053] Specifically, in the scenario where the atomizing component 2 is installed in the second cavity 102, initially the movable part 16 is in the second position and blocks the connecting hole 103. Then, the atomizing component 2 is pushed inward from the port of the second cavity 102, and the atomizing core 40 moves the movable part 16 from the second position to the first position. One end of the atomizing core 40 is also connected to the movable part 16. The atomization channel of the atomizing core 40 leads to the mouthpiece 120 through the movable part 16, and a transition cavity 106 is formed between the movable part 16 and the outer shell 20. In scenario 02, when the atomizing component 2 is disassembled, the aerosol matrix in the atomizer 100 and transition chamber 106 is guided by the conical surface 105 of the movable component 16 and then flows back to the first chamber 101 through the connecting hole 103. When the user applies force to pull the atomizing component 2 outward, the atomizing component 2 moves the movable component 16 outward together, causing the movable component 16 to move from the first position to the second position and block the connecting hole 103, preventing the aerosol matrix in the first chamber 101 from leaking out, and at the same time separating the atomizing core 40 and the movable component 16.

[0054] By further providing a movable part 16 in the second cavity 102, the movable part 16 can move with the atomizing component 2, thereby sealing the connecting hole 103 when the atomizing component 2 is disassembled, preventing the aerosol matrix in the first cavity 101 from leaking out, and avoiding the connecting hole 103 when the atomizing component 2 is installed in the second cavity 102, so that the aerosol matrix in the first cavity 101 can enter the transition cavity 106 to supply liquid to the atomizing component 2.

[0055] In this embodiment, as Figure 3 As shown, the movable component 16 includes a movable cylinder 160 and a tapered end 162 connected to one end of the movable cylinder 160. The movable cylinder 160 is movably assembled with the inner wall surface of the second cavity 102. The outer surface of the tapered end 162 facing the outer shell 20 is a tapered surface 105. A liquid collection groove 164 is formed on the inner surface of the tapered end 162. A liquid collecting component 17 is provided inside the movable cylinder 160 and on the liquid collecting groove 164. The liquid collecting component 17 is provided with an atomization channel 170 that communicates with the atomization channel 401 of the atomizing core 40.

[0056] The outer wall of the movable cylinder 160 may be provided with a sealing ring, which also abuts against the inner wall surface of the second cylinder 102, thereby making the movable member 16 and the inner wall surface of the second cylinder 102 form a movable engagement relationship. That is, when no external force is applied to the movable member 16, the position of the movable member 16 relative to the second cavity 102 remains unchanged, while when an external force is applied to the movable member 16, the movable member 16 can be driven to move within the second cavity 102.

[0057] The conical end 162 has a port that mates with the end of the atomizing core 40, and one end of the atomizing core 40 is sealed to the conical end 162 to prevent leakage. The movable part 16 contains a liquid collector 17 that can absorb condensate. The liquid collector 17 can be made of absorbent material such as cotton or non-woven fabric. It can absorb the condensate that rises with the aerosol and condenses upon cooling, preventing the aerosol from entering the user's mouth and causing a deterioration in taste. It also prevents condensate from flowing back to the atomizing core 40, effectively improving the atomization performance of the atomizer 100.

[0058] When the liquid collecting component 17 absorbs a large amount of condensate, the condensate can be collected in the liquid collecting tank 164 at the conical end 162 under the influence of gravity. That is, the liquid collecting tank 164 can be used to collect condensate, which further improves the liquid collecting capacity.

[0059] Continue reading Figures 3 to 5 ,in Figure 5 yes Figure 4The diagram shows the exploded structure of the atomizing assembly. The outer shell 20 includes a cylindrical body 220 and a base 222. The top end of the cylindrical body 220 is provided with a liquid passage hole 201, and its bottom end is an open end. The base 222 seals the open end of the cylindrical body 220 and defines a liquid supply chamber 205. The atomizing core 40 is connected to the base 222 and the top end of the cylindrical body 220. The base 122 is provided with an air hole communicating with the atomizing core 40.

[0060] Specifically, the liquid passage 201 includes a connecting part 202 and a liquid passage part 203 disposed on at least one side of the connecting part 202. Both the connecting part 202 and the liquid passage part 203 are hole structures that penetrate the top of the cylinder 220. The connecting part 202 is engaged with the atomizing core 40 through a shaft hole. The liquid passage part 203 connects the accommodating cavity inside the housing 20 and the transition cavity 106 outside the housing 20.

[0061] In this embodiment, the connecting part 202 is provided with symmetrical liquid passage parts 203 on both sides, and the ratio of the area of ​​the liquid passage part 203 to the end area of ​​the liquid supply cavity 205 is 0.25 to 0.5, so as to replenish the liquid supply cavity 205 in the accommodating cavity more quickly and evenly.

[0062] Please see Figure 3 , Figure 4 and Figure 6 ,in Figure 6 yes Figure 4 A cross-sectional view of the atomizing core in the atomizing assembly shown.

[0063] The atomizing core 40 includes an atomizing sleeve 41, a liquid suction element 42, and a heating element 43. The side wall of the atomizing sleeve 41 is provided with a liquid inlet 401. The liquid suction element 42 is disposed inside the atomizing sleeve 41 and covers the liquid inlet 401. The heating element 43 is stacked on the side of the liquid suction element 42 away from the liquid inlet 401. The heating element 43 covers the liquid inlet 401 radially along the atomizing sleeve 41.

[0064] The atomizing sleeve 41 has a tubular structure, which can be a single-tube structure or a multi-layer tube structure, with at least one liquid inlet 401 distributed circumferentially, and multiple liquid inlets 401 can be evenly distributed along the axial direction of the atomizing sleeve 41. The liquid suction element 42 can be made of materials such as cotton or non-woven fabric, which can absorb liquid and guide liquid to the heating element 43; or the liquid guiding element 42 can also be porous ceramic or porous glass. The heating element 42 can be a heating mesh or heating film, which can heat the atomized aerosol matrix to generate aerosol within the atomizing channel 401.

[0065] In this embodiment, as Figure 6 As shown, the heating element 43 includes an upper heating mesh 431 and a lower heating mesh 432 that are distributed along the axial direction of the atomizing sleeve 41 and connected to each other.

[0066] Please refer to the following: Figure 6 and Figure 7,in Figure 7 yes Figure 6 The diagram shows the exploded structure of the atomizing sleeve in the atomizing core.

[0067] The atomizing sleeve 41 includes a first sleeve 411 and a second sleeve 412. The second sleeve 412 is fitted inside the first sleeve 411 with an interference fit. The first sleeve 411 is provided with a first liquid inlet 413, and the second sleeve 412 is provided with a second liquid inlet 414. The first liquid inlet 413 and the second liquid inlet 414 are stacked to form a liquid inlet 401. A ventilation groove 415 is formed on the wall of the second sleeve 412. The inner wall surface of the first sleeve 411 and the outer surface surface of the liquid suction element 42 respectively cover the inner and outer sides of the ventilation groove 415, and together with the ventilation groove 415, they form a ventilation channel that connects the atmosphere and the second liquid inlet 414.

[0068] Specifically, the ventilation channel is connected to the atomization channel 401 of the atomizing core 40. When the air pressure in the first cavity 101 is unbalanced, air can be replenished to it through the ventilation channel to avoid insufficient liquid supply to the atomizing core 40 due to the low air pressure in the first cavity 101.

[0069] The ventilation groove 415 is a through groove on the wall of the second sleeve 412, that is, it penetrates the wall of the second sleeve 412. Therefore, the process of forming the ventilation groove 415 on the wall of the second sleeve 412 is simple and efficient, which greatly saves processing time and improves processing efficiency.

[0070] By configuring the atomizing sleeve 41 as a first sleeve 411 and a second sleeve 412 that can be interference-fitted, an air exchange groove 415 can be easily formed in the second sleeve 412. Through the cooperation with the inner wall surface of the first sleeve 411 and the outer surface of the liquid suction element 42, an air exchange channel for air exchange can be formed. Compared with directly processing the air exchange groove 415 on the inner wall of the atomizing sleeve 41, the scheme of forming the air exchange channel adopted in this application has higher processing efficiency and lower cost.

[0071] The ventilation trough 415 is installed on the second sleeve 412 and covered by the liquid suction component 42, which can effectively prevent the ventilation trough 415 from being filled with liquid aerosol matrix, resulting in poor ventilation effect.

[0072] In this embodiment, the second sleeve 412 has a ventilation groove 415 that connects to the second liquid inlet 414 on its pipe wall. That is, one end of the ventilation groove 415 is directly connected to the second liquid inlet 414, and the ventilation channel directly exchanges air through the second liquid inlet 414, which can greatly improve its ventilation efficiency and reduce the difficulty of ventilation.

[0073] Optionally, the ventilation trough 415 is isolated from the second liquid inlet 414, and ventilation is achieved through the suction element 42. That is, the ventilation trough 415 is not directly connected to the second liquid inlet 414, and the ventilation channel needs to exchange air with the first cavity 101 through the suction element 42. The suction element 42 has a porous structure inside, and the gas entering exchanges air with the first cavity 101 along its pores.

[0074] Furthermore, both the first sleeve 411 and the second sleeve 412 are rigid pipes, which can effectively prevent the ventilation effect from being impaired due to the deformation of the ventilation channel and can better maintain the stability of the ventilation channel.

[0075] The atomizing sleeve 41 has multiple liquid inlets 401 spaced apart along its circumference. Each liquid inlet 401 includes a first liquid inlet 413 and two second liquid inlets 414 corresponding to the first liquid inlet 413. The two second liquid inlets 414 are axially spaced along the wall of the second sleeve 412 and correspond to the upper heating mesh 431 and the lower heating mesh 432, respectively. The ventilation groove 415 is connected to the second liquid inlet 414 corresponding to the upper heating mesh 431.

[0076] In this embodiment, the ventilation groove 415 is connected to the second liquid inlet 414 corresponding to the upper heating mesh 431, which can greatly shorten the path from the port of the ventilation groove 415 to the liquid passage hole 201, making the ventilation smoother and reducing the attenuation effect of the liquid storage component 30 on the ventilation effect.

[0077] Furthermore, the dimension of the first inlet 413 along the circumference of the first sleeve 411 is smaller than the dimension of the second inlet 414 along the circumference of the second sleeve 412. The aerosol matrix flows to the suction element 42 sequentially through the first inlet 413 and the second inlet 414. By setting the first inlet 413 with a relatively smaller diameter, the excessively fast conduction rate of the aerosol matrix is ​​effectively limited, so that it has an appropriate liquid conduction rate.

[0078] The second sleeve 412 is provided with multiple sets of second liquid inlets 414 along the circumferential direction. The ventilation groove 415 is provided between two adjacent sets of second liquid inlets 414. The ventilation groove 415 includes a first ventilation section 416 and a second ventilation section 417 that are connected. The first ventilation section 416 is connected to one side of the second liquid inlet 414 in the circumferential direction. The second ventilation section 417 extends along the axial direction of the second sleeve 412 to the bottom of the second liquid inlet 414 corresponding to the lower heating mesh 431 and the end of the second sleeve 412.

[0079] By defining the position and path of the ventilation channel 415 as described above, the ventilation path can be effectively shortened and the ventilation efficiency improved. At the same time, the end of the second ventilation section 417 away from the first ventilation section 416 is located between the bottom of the second liquid inlet 414 and the end of the second sleeve 412, without directly cutting off the end of the second sleeve 412. Therefore, the second sleeve 412 can still maintain relatively good structural strength and avoid deformation, thus effectively maintaining the stability of the ventilation channel.

[0080] Unlike existing technologies, this application discloses an electronic atomizing device and its atomizer. In this application, the liquid supply chamber surrounding the atomizing core is an empty cavity without a liquid storage cotton. Therefore, the atomizing core can directly contact the aerosol matrix. By eliminating the liquid storage cotton, the obstruction to aerosol matrix conduction by the cotton is eliminated, allowing the aerosol matrix to enter the atomizing core more quickly and preventing core clogging due to untimely aerosol supply. Furthermore, the ratio of the volume of the first chamber to the volume of the liquid supply chamber is 3-10, ensuring that the liquid supply chamber stores an appropriate amount of aerosol matrix. This balances reducing the risk of leakage with ensuring sufficient and timely liquid supply to the atomizing core, preventing dry burning. Simultaneously, it eliminates the adsorption of fragrance and flavor substances from the aerosol matrix by the liquid storage cotton, increasing the original flavor reproduction of the aerosol.

[0081] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
