[0002] This application claims priority to Chinese Patent Application No. 2024115305896, filed on October 30, 2024, entitled "Atomizer and Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

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

[0004] The atomizer has an atomizing component and a liquid storage chamber inside. The liquid storage chamber stores the atomizing matrix. The atomizing component draws in the atomizing matrix through the liquid guide and heats the atomizing matrix on the liquid guide through the heating element to generate an aerosol for the user to inhale.

[0005] In related technologies, conventional atomizing components only have one layer of liquid guiding element. In order to ensure the atomizing function of the atomizing component, the pore size of the internal micropores of the liquid guiding element is set to be large enough to adsorb a sufficient amount of atomizing matrix. However, the liquid locking effect is poor. When the components are placed on the shelf for a long time or subjected to vibration during transportation, leakage is very likely to occur due to the poor liquid locking effect of the liquid guiding element, which reduces the user experience. Summary of the Invention

[0006] This application provides an atomizer and atomizing device, solving the technical problems of poor sealing and easy leakage in existing atomizers. The aperture of the first liquid guiding element of the atomizer in this application is smaller than that of the second liquid guiding element.

[0014] In some embodiments, the atomizer further includes a bottom cover, which is fixed to one end of the housing facing away from the air duct and at least partially abuts against the mounting base; the bottom cover defines an air inlet chamber between the mounting base and the inner wall of the housing, and the vent hole communicates with the air inlet chamber; the bottom cover is provided with at least two air inlets communicating with the air inlet chamber and the outside atmosphere.

[0015] In some embodiments, the axes of the at least two air inlets are misaligned with the axis of the vent; and / or, the atomizer further includes a first sealing member and a second sealing member, the first sealing member being detachably mounted on the bottom cover and sealing one air inlet end of the air inlet, and the second sealing member being detachably mounted on the air outlet and sealing one air outlet end of the air guide tube.

[0016] In some embodiments, the atomizer further includes at least one ventilation channel, which is disposed on the cavity wall of the mounting cavity.

[0020] The atomizer provided in this application includes a housing, a mounting base, a liquid guiding assembly, and a heating element. The atomizing matrix is ​​stored in a liquid storage cavity defined between the mounting base and the housing. The mounting base is fixed in the housing and has a mounting cavity communicating with the liquid storage cavity. The liquid guiding assembly is housed in the mounting cavity and includes a first liquid guiding member and a second liquid guiding member.

The heating element is housed in the atomizing air channel. The first liquid guiding member is sleeved around the second liquid guiding member and they are in fluid communication. The first liquid guiding member is at least partially communicating with the liquid storage cavity to adsorb the atomizing matrix in the liquid storage cavity and transfer it to the second liquid guiding member, so that the atomizing matrix can be heated by the heating element at the atomizing air channel of the second liquid guiding member to generate an aerosol and achieve atomization and smoke generation for the user to inhale.

[0021] The atomizer using the technical solution of this application has the following beneficial effects:

[0022] (1) Since the density of the first liquid guide is greater than that of the second liquid guide, the relatively larger density can bring better oil locking effect, which significantly improves the liquid locking effect of the liquid guide assembly; in addition, the increase of the liquid inlet channel reduces the contact area between the first liquid guide and the oil storage cavity, so that the first liquid guide can achieve consistent liquid supply balance in the transmission of the atomizing matrix, and reduce the risk of leakage.

[0023] (2) An air exchange channel is added between the atomizing component and the fixed base to effectively regulate the pressure inside the liquid storage chamber, further reduce the risk of leakage, and improve the user experience. Attached Figure Description

[0047] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the order of the steps or actions in the method description can be changed or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0048] Please refer to Figures 1 to 2 and Figures 8 to 9. In some embodiments of this application, an atomizer 10 is provided. The atomizer 10 includes a housing 1, a fixing base 2, and an atomizing assembly 3. The fixing base 2 is fixed in the housing 1. Preferably, the fixing base 2 is sealed and embedded in the housing 1 by an interference fit, and the fixing base 2 is provided with an axially arranged mounting cavity 22 communicating with the liquid storage cavity 4 (as shown in Figure 9).

[0049] Please refer to Figures 2 and 9. The atomizing component 3 is housed in the mounting cavity 22 and is used to heat the atomizing matrix and generate an aerosol. The atomizing component 3 includes a liquid guiding component 30 and a heating element 34. The liquid guiding component 30 includes a first liquid guiding element 31 and a second liquid guiding element 33. The second liquid guiding element 33 is isolated from the liquid storage cavity 4, and an atomizing air channel 331 is formed on the side of the second liquid guiding element 33 facing away from the first liquid guiding element 31. The atomizing air channel 331 preferably extends through both ends of the second liquid guiding element 33 in the axial direction. The heating element is housed in the atomizing air channel 331 and is at least partially attached to the inner wall surface of the second liquid guiding element 33 for atomizing the atomizing matrix transferred by the second liquid guiding element. The first liquid guiding component 31 is sleeved around the second liquid guiding component 33 and is in fluid communication with it. At least a portion of the first liquid guiding component 31 is in communication with the liquid storage cavity 4. It is used to adsorb the atomizing matrix in the liquid storage cavity 4 and transfer it to the second liquid guiding component 33, so that the atomizing matrix can be heated by the heating element 34 at the atomizing air passage 331 of the second liquid guiding component 33 to generate aerosol and achieve atomization and smoke generation for the user to inhale.

[0050] The density of the first liquid guiding component 31 is greater than the density of the second liquid guiding component 33.

[0051] The atomizer 10 provided in this application utilizes a first liquid guide 31 to adsorb the atomizing matrix and transfer it to a second liquid guide 33, thus performing the functions of liquid absorption, storage, and guidance, ensuring a continuous and stable supply of the atomizing matrix. Furthermore, the density of the first liquid guide 31 is greater than that of the second liquid guide 33, resulting in greater compactness. In addition to adsorbing, storing, and transferring the atomizing matrix, it also has a better liquid-locking effect, capable of storing sufficient atomizing matrix and effectively controlling the rate at which the atomizing matrix is ​​transferred to the second liquid guide 33. This ensures a continuous and stable supply of the atomizing matrix during suction use and effectively avoids leakage of the atomizing matrix caused by prolonged shelf placement or vibration during transportation, thereby improving the user experience.

[0052] Please refer to Figures 4 and 9. In some embodiments, the mounting base 2 is further provided with a liquid guiding groove 21 on the side facing the liquid storage cavity 4. The first liquid guiding member 31 is fixed in the mounting base 2, and the first liquid guiding member 31 extends into the liquid guiding groove 21 at the upper end facing the liquid storage cavity 4. The housing 1 and the groove wall of the liquid guiding groove 21 together define the liquid inlet channel 41, and the liquid guiding assembly 30 at least covers the liquid inlet channel 41.

[0053] The liquid inlet channel 41 is preferably formed at the lower end of the liquid storage chamber 4 in the direction of gravity. It can guide the atomized matrix in the liquid storage chamber 4 to the first liquid guide member 31 of the liquid guide assembly 30, which plays the role of guiding and limiting the flow, reducing the contact area between the first liquid guide member 31 and the liquid storage chamber 4, thereby controlling the liquid absorption efficiency and liquid absorption volume of the first liquid guide member 31. This enables the first liquid guide member 31 to achieve a consistent liquid supply balance in the transmission of the atomized matrix, preventing the liquid guide imbalance of the atomized assembly 3 caused by the second liquid guide member 33 being greater than the consumption rate of the atomized matrix during use, and thus significantly reducing the risk of leakage.

[0054] Referring to Figures 4 and 9, in one specific embodiment, the liquid guiding groove 21 is disposed at the upper end of the fixing base 2 facing the liquid storage cavity 4 and is axially recessed into the fixing base 2 to communicate with the mounting cavity 22. The inner diameter of the liquid guiding groove 21 is larger than the inner diameter of the mounting cavity 22, so that the liquid guiding groove 21 surrounds the end of the mounting cavity 22 facing the liquid storage cavity 4. The first liquid guiding component 31 is preferably configured as a hollow cylindrical tubular structure, the outer diameter of which matches the inner diameter of the mounting cavity 22 and is smaller than the inner diameter of the liquid guiding groove 21, so that the upper end of the first liquid guiding component 31 at least partially extends to and blocks the liquid inlet channel 41, thereby uniformly guiding the atomized matrix to the first liquid guiding component 31, and the liquid absorption of the first liquid guiding component 31 can be controlled by the channel capacity of the surrounding liquid inlet channel 41.

[0055] The upper end of the first liquid guide 31 extends into the liquid guide groove 21 and communicates with the liquid inlet channel 41. The lower part of the first liquid guide 31 is inserted and fixed in the mounting cavity 22 by an interference fit, so that at least a portion of the lower outer wall surface of the first liquid guide 31 can seal against the cavity wall of the mounting cavity 22 and form a good seal. The second liquid guide 33 is housed in the first liquid guide 31 and forms fluid communication with the first liquid guide 31. Combined with the design that the density of the first liquid guide 31 is greater than that of the second liquid guide 33, the first liquid guide 31 can better lock in the atomizing matrix, effectively preventing the atomizing matrix in the liquid inlet channel 41 from leaking out through the gap between the outer wall surface of the first liquid guide 31 and the cavity wall of the mounting cavity 22, further improving the sealing performance of the atomizer 10 of this application.

[0056] In other embodiments, multiple liquid guiding grooves 21 can be provided, which are radially recessed at the end of the cavity wall of the mounting cavity 22 facing the liquid storage cavity 4. Preferably, the multiple liquid guiding grooves 21 are centrally symmetrically distributed with the axis of the mounting cavity 22 as the center, so that the multiple liquid guiding grooves 21 are circumferentially distributed at the end of the mounting cavity 22 facing the liquid storage cavity 4. This defines multiple circumferentially distributed distributed liquid inlet channels 41 on the upper end of the first liquid guiding component 31 between the housing 1 and the groove walls of the multiple liquid guiding grooves 21. The atomized matrix can be guided from different positions to the first liquid guiding component 31 through the distributed multiple liquid inlet channels 41. By adjusting the number, capacity, and position of the liquid guiding grooves 21, the liquid absorption and distribution effect of the liquid guiding component 30 per unit time can be controlled, preventing the atomized matrix in the liquid guiding component 30 from being oversaturated or unevenly distributed.

[0057] In some embodiments, the length of the first liquid guide 31 extending into the liquid guide groove 21 is between 1% and 40% of the total length of the first liquid guide 31. This ensures that the lower part of the first liquid guide 31 has sufficient length to be inserted into the mounting cavity 22 and to have an interference fit with the mounting cavity 22, thus guaranteeing the stability and reliability of the atomizing assembly 3 housed in the mounting cavity 22. On the other hand, it also ensures that less than half of the upper end of the first liquid guide 31 is directly immersed in the atomizing matrix, reducing the contact area between the first liquid guide 31 and the atomizing matrix. This allows the first liquid guide 31 to achieve consistent liquid supply balance in the transmission of the atomizing matrix, preventing the first liquid guide 31 from becoming oversaturated and leaking liquid. This further improves the sealing performance of the atomizer 10 of this application and reduces the risk of leakage.

[0058] Referring to Figure 9, in some embodiments, the liquid guiding groove 21 has a guide surface 211 on the side facing the liquid storage cavity 4. The guide surface 211 extends obliquely from the end of the fixing seat 2 near the liquid storage cavity 4 towards the lower end of the fixing seat 2 opposite to the liquid storage cavity 4, and gradually converges at the end of the first liquid guiding member 31 that extends into the liquid guiding groove 21, so that the vertical cross section of the liquid guiding groove 21 is wedge-shaped. The guide surface 211 can be a plane or a curved surface. This application does not limit this, as long as the atomizing matrix can be guided to the first liquid guiding member 31 through the guide surface 211.

[0059] Referring to Figure 9, in one specific embodiment, the bottom wall of the liquid guiding groove 21 is configured with an annular guide surface 211, whose inner diameter gradually decreases from the upper end facing the liquid storage cavity 4 to the lower end facing away from the liquid storage cavity 4, forming a funnel-like shape. This allows the atomizing matrix in the liquid inlet channel 41 at the bottom of the liquid storage cavity 4 to be guided by the guide surface 211 and flow evenly to the upper end of the first liquid guiding member 31 that extends into the liquid guiding groove 21, further improving the consistency of liquid output from the liquid storage cavity 4 and enhancing the heating and atomization effect of the atomizing assembly 3 on the atomizing matrix. In addition, the converging structure design of the bottom wall of the liquid guiding groove 21 also facilitates the axial insertion of the atomizing assembly 3 into the mounting cavity 22 via the liquid guiding groove 21, resulting in a higher fault tolerance and facilitating the automated assembly of the atomizer 10.

[0060] The upper end of the first liquid guiding element 31 of the liquid guiding assembly 30 of this application directly adsorbs the atomizing matrix in the liquid inlet channel 41 in the annular liquid guiding groove 21, playing the roles of liquid absorption, liquid storage and liquid guiding. Combined with the structural design of the annular guide surface 211 of the liquid guiding groove 21, the atomizing matrix can be uniformly transferred to the first liquid guiding element 31 in all directions. The first liquid guiding element 31 and the second liquid guiding element 33 are fluidly connected to each other by the capillary phenomenon between the micropores of the material itself and transfer the atomizing matrix, so that the atomizing matrix on the first liquid guiding element 31 can be uniformly transferred to the second liquid guiding element 33, and then heated by the heating element 34 housed in the atomizing air channel 331, ensuring that the atomizing matrix can be uniformly heated to atomization, ensuring the consistency of taste during inhalation, and avoiding the problem of core clogging caused by uneven distribution of atomizing matrix. Furthermore, the atomizer 10 of this application has optimized the length of the first liquid guiding element 31 extending into the liquid guiding groove 21, and the density of the first liquid guiding element 31 is set to be greater than the density of the second liquid guiding element 33. This can further control the liquid absorption volume and the liquid guiding efficiency of the liquid guiding component 30, ensuring the balance between the supply and demand of the atomizing matrix while achieving better liquid locking effect, and further reducing the risk of leakage of the atomizer 10.

[0061] In addition, the first liquid guide 31 can store a certain amount of atomizing matrix, which increases the overall liquid storage capacity of the liquid guide assembly 30. It can quickly transfer the atomizing matrix to the second liquid guide 33 during the suction process, ensuring the continuity of oil supply and the consistency of the atomized gas concentration of each inhale, thus improving the user's inhalation experience.

[0062] Please refer to Figures 1 to 3. The housing 1 is commonly known in the art as an oil cup. In some embodiments, the housing 1 is preferably made of PP plastic and has an internal cavity 11. The housing 1 is vertically arranged along the direction of gravity. The upper end of the housing 1 is provided with a suction nozzle 13 and the lower end is provided with a mounting slot 14. The suction nozzle 13 forms an air outlet 15 on the housing 1 (as shown in Figure 2). The upper end of the cavity 11 is connected to the outside through the air outlet 15, and the lower end of the cavity 11 is connected to the outside through the mounting slot 14.

[0063] Please refer to Figures 8 and 9. The housing 1 also includes an air guide pipe 12 that communicates with the outside through the air outlet 15. Both the first liquid guide component 31 and the second liquid guide component 33 are tubular. The air guide pipe 12 extends downwards into the liquid guide groove 21 of the fixing base 2 and abuts against the first liquid guide component 31. One end of the atomizing air passage 331 communicates with the air guide pipe 12 and with the outside through the air outlet 15. The outer wall of the air guide pipe 12, the fixing base 2, the upper end of the first liquid guide component 31 extending into the liquid guide groove 21, and the inner wall of the housing 1 together define the liquid storage chamber 4.

[0064] Please refer to Figures 4, 8 and 9. Correspondingly, a fixed platform 221 is provided on the cavity wall of the mounting cavity away from the air guide tube 12. The two ends of the first liquid guide 31 in the axial direction are fixedly clamped between the fixed platform 221 and the air guide tube 12, and the outer wall surface of the first liquid guide 31 is at least partially sealed against the cavity wall of the mounting cavity 22, so as to limit the first liquid guide 31 through the fixed seat 2 and the air guide tube 12.

[0065] The fixing base 2 is preferably made of PP plastic. During assembly, the lower end of the atomizing component 3 can be axially inserted into the mounting cavity 22 of the fixing base 2, so that the atomizing component 3 and the fixing base 2 are assembled into a vertical assembly. Then, the vertical assembly is axially inserted into the housing 1 through the mounting slot 14, so that the upper end of the first liquid guide 31 abuts against the air guide tube 12 and the lower end of the first liquid guide 31 abuts against the fixing platform 221. The outer wall of the fixing base 2 is sealed and embedded in the inner wall of the receiving cavity 11 of the housing 1 in an interference fit, and a good seal is formed between the fixing base 2 and the housing 1 to prevent leakage.

[0066] The air guide tube 12 of the atomizer 10 of this application is configured to extend into the liquid guide groove 21 of the fixed base 2. Together with the mounting cavity 22, it further restricts the axial length of the first liquid guide 31, which can prevent the upper end of the first liquid guide 31 from extending out of the liquid guide groove 21 and being immersed too much in the liquid storage cavity 4, and avoid the first liquid guide 31 from becoming oversaturated due to adsorbing too much atomizing matrix, thereby further reducing the risk of leakage of the atomizer 10.

[0067] In addition, the fixing seat 2 and the housing 1 in the atomizer 10 of this application are fixedly assembled by an interference fit, which can achieve a good seal between the outer wall of the fixing seat 2 and the inner wall of the housing 1, ensuring that the atomizer 10 is not prone to leakage during transportation, shelf life and use, and can eliminate the need for the silicone sealing ring, avoiding the problem of aroma decay caused by the atomizing matrix in the liquid storage chamber 4 directly contacting the silicone material.

[0068] Please refer to Figures 3 and 8. In some embodiments, the cross-sectional shape of the receiving cavity 11 of the housing 1 on the horizontal plane is preferably set to be circular, and the air guide tube 12 extends axially from the air outlet 15 to the mounting slot 14 side along the axis of the receiving cavity 11.

[0069] Please refer to Figures 4 and 9. Correspondingly, the fixing base 2 is configured as a cylindrical structure that fits into the inner wall of the receiving cavity 11 of the housing 1. The mounting cavity 22 is preferably configured to extend along the axial center line A of the atomizer 10 and be coaxial with the receiving cavity 11. In this way, the housing 1, fixing base 2, atomizing assembly 3, and other components of the atomizer 10 of this application can be automatically assembled by axial stacking. Compared with the existing design, it has the advantages of simple structure, fewer parts, and convenient installation, which can significantly reduce the production cost of the atomizer 10.

[0070] Please refer to Figures 4, 5 and 9. In some embodiments, a vent hole 251 is provided through one end of the air guide tube 12 behind the fixed base 2. The vent hole 251 is preferably located at the center of the bottom of the mounting cavity 22 to connect the external space of the fixed base 2 with the mounting cavity 22. The vent hole 251 is also connected to the atomizing air channel 331 in the second liquid guide 33 so that outside air can enter the atomizing air channel 331 through the vent hole 251 and mix with the aerosol generated by atomization to form atomized gas.

[0071] Please refer to Figures 4 and 9. In some embodiments, the fixing platform 221 is preferably arranged around the lower cavity wall of the mounting cavity 22 and in contact with the bottom surface of the mounting cavity 22, so that the inner side of the fixing platform 221 forms an annular inner wall, and the vent 251 is provided at the center of the inner wall of the fixing platform 221.

[0072] In some other embodiments, the fixing platform 221 may also be configured as multiple platforms, circumferentially distributed on the lower cavity wall of the mounting cavity 22, and the inner sides of the multiple fixing platforms 221 together form a discontinuous annular inner wall structure, with the vent 251 located at the center of the inner wall of the fixing platform 221.

[0073] Referring to Figures 2 and 9, in some embodiments, the atomizing assembly 3 further includes an atomizing tube 32. The upper end of the atomizing tube 32 facing the liquid storage chamber 4 is inserted into the air guide tube 12 and connected to the air outlet 15. The lower end of the atomizing tube 32 facing away from the liquid storage chamber 4 is inserted into the mounting cavity 22 and connected to the vent hole 251. At least one liquid inlet 321 is provided through the tube wall of the atomizing tube 32.

[0074] Please refer to Figures 6, 8, and 9. After the atomizing component 3 is assembled, the second liquid guiding element 33 is housed within the atomizing tube 32, and at least partially closes the liquid inlet 321 from the inside; the first liquid guiding element 31 is sleeved on the outside of the atomizing tube 32, and at least partially closes the liquid inlet 321 from the outside. The heating element 34 is housed within the second liquid guiding element 33 and is electrically connected to an external power source. In actual use, the atomizing matrix adsorbed on the first liquid guiding element 31 is transferred to the second liquid guiding element 33 through the liquid inlet 321, achieving fluid communication between the first liquid guiding element 31 and the second liquid guiding element 33. The heating element 34 performs work and generates heat under electric drive, thereby heating the atomizing matrix on the inner wall surface of the second liquid guiding element 33, within the working range of the heating element 34, to atomization and generating an aerosol.

[0075] In one specific embodiment, the outer diameter of the atomizing tube 32 preferably matches the inner diameter of the annular inner wall of the fixing platform 221, so that the lower end of the atomizing tube 32 can be fixedly inserted into the fixing platform 221 with an interference fit, and the lower outer wall surface of the atomizing tube 32 at least partially seals against the annular inner wall of the fixing platform 221 to form a good seal. Correspondingly, the inner wall of the air guide tube 12 facing the lower end of the fixing base 2 is provided with an insertion groove (not shown) whose inner diameter matches the outer diameter of the atomizing tube 32. During assembly, the lower end of the atomizing tube 32 is inserted and fixed on the annular inner wall of the fixing platform 221, and the upper end of the atomizing tube 32 is inserted and fixed on the insertion groove at the lower end of the air guide tube 12.

[0076] After insertion and fixing, the outer wall of the atomizing tube 32, the cavity wall of the mounting cavity 22, and the upper end face of the fixing platform 221 facing the liquid storage cavity 4 together define the limiting space for fixing and holding the lower part of the first liquid guide 31, ensuring that the atomizing assembly 3 can be stably and reliably inserted and fixed in the fixing seat 2.

[0077] Multiple liquid inlets 321 are preferably provided, arranged symmetrically or centrally symmetrically around the axis of the atomizing tube 32, so that the atomizing matrix can be uniformly delivered to the second liquid guiding component 33 through multiple liquid inlets 321, ensuring the uniformity of liquid guiding of the second liquid guiding component 33.

[0078] In actual use, the user inhales through the mouthpiece 13 at the upper end of the housing 1, creating a negative pressure inside the housing 1. Outside air enters the atomizing tube 32 through the vent 251 and flows into the atomizing air passage 331 within the second liquid guide 33. Simultaneously, the atomizing matrix in the liquid storage chamber 4, guided by the liquid inlet channel 41, flows along the guide surface 211 of the liquid guide groove 21 to the first liquid guide 31, where it is adsorbed and transferred through the liquid inlet 321 to the second liquid guide 33. The second liquid guide 33 then transfers the matrix to its inner wall surface, where it is heated by the heating element 34 to atomize and generate an aerosol. The generated aerosol mixes with the airflow in the atomizing air passage 331 to form atomized gas. The atomized gas is finally discharged through the air outlet 15 via the air guide tube 12 for the user to inhale.

[0079] Please refer to Figures 4 and 9. In some embodiments, the mounting base 2 is also provided with a vent 25. The vent 25 is a hollow tubular structure that extends axially from the bottom surface of the mounting cavity 22 to the annular inner wall of the mounting platform 221. The bottom of the vent 25 penetrates the bottom end of the back-to-back air guide tube 12 of the mounting base 2 and forms the vent hole 251. The vent 25 can, on the one hand, introduce the air entering through the vent hole 251 into the atomizing tube 32 and send it to the atomizing air passage 331. On the other hand, it can also define a bottom annular groove 23 between the bottom surface of the mounting cavity 22 and the annular inner wall of the mounting platform 221. During use, a certain amount of atomizing matrix can be accumulated through the bottom annular groove 23, which can prevent the atomizing matrix that has leaked into the mounting cavity 22 from leaking out directly through the vent hole 251.

[0080] In addition, the air entering the atomizing tube 32 through the ventilation section 25 can flow downwards and meander into the bottom annular groove 23 and accumulate, reducing the risk of oil splattering during use, increasing the airflow supply in the atomizing tube 32, increasing the concentration of atomized gas per puff, and improving the user's smoking experience.

[0081] Please refer to Figures 1 to 3 and Figure 8. In some embodiments, the atomizer 10 also includes a bottom cover 6, which is preferably snapped and fixed to the bottom mounting slot 14 of the back air guide tube 12 of the housing 1. At least a portion of the bottom cover 6 abuts against the fixing seat 2 to limit the fixing seat 2 and prevent the fixing seat 2 from loosening from the inner wall of the housing 1.

[0082] Please refer to Figures 8 and 9. After the bottom cover 6 is snapped and fixed in the mounting slot 14, it can define the air intake chamber 5 between the fixed base 2 and the inner wall of the housing 1. The vent 251 is connected to the air intake chamber 5.

[0083] Please refer to Figures 7 and 9. The bottom cover 6 is provided with at least two air inlets 621 that connect the air inlet chamber 5 to the outside atmosphere.

[0084] During assembly, the atomizing component 3 and the fixing base 2 can be assembled first to form a vertical assembly. Then, the vertical assembly is axially inserted into the housing 1 through the mounting slot 14. Finally, the bottom cover 6 is axially installed onto the mounting slot 14 at the bottom of the housing 1, and the fixing base 2 and the atomizing component 3 are fixed in the housing 1 by the bottom cover 6 pressing against the fixing base 2.

[0085] The atomizer 10 provided in this application is assembled from a housing 1, a fixing base 2, an atomizing component 3 and a bottom cover 6. The overall structure is relatively simple and has few components. Each component can be stacked in the axial direction, which facilitates automated assembly and helps reduce production and manufacturing costs.

[0086] In actual use, the user's suction nozzle 13 creates a negative pressure inside the housing 1. Under the action of the pressure difference, the air outside the housing 1 enters the air intake chamber 5 through at least two air inlets 621 on the bottom cover 6. The air in the air intake chamber 5 then enters the atomizing tube 32 through the vent 251.

[0087] Referring to Figure 9, in some embodiments, the axes of at least two air inlets 621 are misaligned with the axis of the vent 251. This prevents air from the outside atmosphere from flowing directly into the vent 251 through the air inlets 621, causing some air to flow in a circuitous manner within the air intake chamber 5. This further reduces the problems of oil splattering and uneven atomization particles caused by direct airflow during use. Additionally, the misaligned arrangement also prevents the vent 25 from dripping condensate or atomizing matrix leaking from the mounting cavity 22 directly into the air inlets 621 through the vent 251, thus avoiding leakage.

[0088] Please refer to Figures 7 to 9. In some embodiments, the bottom cover 6 is also provided with an air inlet 62. The air inlet 62 is a hollow tubular structure that extends axially from the bottom surface of the bottom cover 6 into the air inlet cavity 5. The bottom of the air inlet 62 penetrates the bottom end of the bottom cover 6 behind the air guide pipe 12 and forms an air inlet 61 communicating with the outside atmosphere (as shown in Figure 10). The upper part of the air inlet 62 facing the fixed base 2 is at least partially closed and has several branch pipes (not shown) extending axially. The branch pipes are arranged in a centrally symmetrical manner with the axis of the air inlet 62 as the center. Each branch pipe has an air inlet hole 621 axially penetrating through its upper end.

[0089] During use, air from the outside atmosphere first enters the air intake section 62 through the air inlet 61, then flows through the branch pipes to the air inlets 621 and merges into the air intake chamber 5. It then enters the bottom annular groove 23 through the vent 251 and the air intake section 25. Because the axes of the air inlets 621 and the vent 251 are misaligned, the airflow exiting the air inlets 621 forms a meandering airflow in the air intake chamber 5 due to the obstruction of the bottom end face of the mounting base 2, further reducing the risk of oil splattering during atomizer 10 use.

[0090] Referring to Figures 2 and 8, in some embodiments, the atomizer 10 further includes a first sealing member 64 and a second sealing member 16. The first sealing member 64 is detachably installed on the air inlet 61 of the bottom cover 6 and seals the air inlet end of each air inlet hole 621, thus sealing the air inlet 62. The second sealing member 16 is detachably installed on the air outlet 15 of the mouthpiece 13 and seals the air outlet end of the air guide tube 12. In the non-use state, the air inlet 61 and air outlet 15 of the atomizer 10 can be sealed by the first sealing member 64 and the second sealing member 16. On the one hand, this can prevent dust from entering the air inlet 61 and air outlet 15, and on the other hand, it can seal the atomizer 10 to maintain the air pressure balance inside and outside the atomizer 10, prevent the atomizing matrix in the liquid storage chamber 4 from leaking out, and ensure that there is no easy leakage during transportation, shelf life, and use.

[0091] Please refer to Figures 2 and 6. In some embodiments, the heating element 34 includes a heating mesh 341 and electrode pins 342. The heating mesh 341 is preferably wound into a cylindrical structure and housed in the second liquid guiding element 33, and the cylindrical heating mesh 341 is attached to the inner wall surface of the second liquid guiding element 33.

[0092] Please refer to Figures 7 to 9. One end of the electrode pin 342 is electrically connected to the heating mesh 341, and the other end of the electrode pin 342 extends out of the mounting cavity 22 away from the air guide tube 12 and abuts against the end of the fixed base 2 located in the air inlet cavity 5.

[0093] Correspondingly, the bottom cover 6 is provided with a conductive element 7. One end of the conductive element 7 extends into the air intake chamber 5 and at least partially abuts against the electrode pin 342 to establish an electrical connection with the heating mesh 341. The other end of the conductive element 7 extends out of the bottom cover 6 away from the fixing base 2 and abuts against the bottom surface of the bottom cover 6 away from the housing 1, forming an electrode plate (not shown) to facilitate connection to an external power source to supply power to the heating element 34.

[0094] Please refer to Figures 6 to 8. In one specific embodiment, the heating element 34 has a heating mesh 341, and the electrode pin 342 includes a positive pin 3421 and a negative pin 3422. The positive pin 3421 and the negative pin 3422 do not contact each other.

[0095] Correspondingly, the conductive component 7 includes a positive conductive component 71 and a negative conductive component 72. The upper end of the positive conductive component 71 abuts against the positive lead 3421, and the lower end of the positive conductive component is attached to the bottom surface of the bottom cover 6 to form a positive electrode plate 711. The upper end of the negative conductive component 72 abuts against the negative lead 3421, and the lower end of the negative conductive component 72 is attached to the bottom surface of the bottom cover 6 to form a negative electrode plate 721.

[0096] Please refer to Figures 4 and 5. The bottom of the mounting base 2 is also provided with two through holes 27, one for the positive pin 3421 and the other for the negative pin 3422, extending out of the mounting cavity 22. Both through holes 27 penetrate the bottom annular groove 23. The bottom end face of the mounting base 2 facing away from the air guide tube 12 is also provided with two recessed pin positioning grooves 28, each connecting to the corresponding through holes 27. After assembly, the positive pin 3421 and the negative pin 3422 of the heating element 34 extend out of the mounting cavity 22 through the corresponding through holes 27 and are then bent and inserted into the corresponding pin positioning grooves 28. The upper end of the positive conductive element 71 is at least partially inserted into the corresponding pin positioning groove 28 and abuts against the positive pin 3421. The upper end of the negative conductive element 72 is at least partially inserted into the corresponding pin positioning groove 28 and abuts against the negative pin 3422, thus establishing an electrical connection between the conductive element 7 and the heating element 34.

[0097] Please refer to Figures 7 to 9. In some embodiments, the bottom of the bottom cover 6 is also provided with two positioning support parts 63 extending axially towards one end of the fixed base 2. The two positioning support parts 63 are symmetrically arranged with the axial center line A of the atomizer 10 as the axis. The two positioning support parts 63 are distributed on both sides of the air inlet 62, and both positioning support parts 63 extend beyond the air inlet 621.

[0098] Please refer to Figure 5. Correspondingly, the bottom end of the mounting base 2, facing away from the air duct 12, has two recessed positioning grooves 26. After assembly, the two positioning support parts 63 on the bottom cover 6 are respectively inserted into the corresponding positioning grooves 26 and stopped at the end faces of the positioning grooves 26. On the one hand, the positioning support parts 63 can limit and fix the assembly of the mounting base 2 and the atomizing component 3 inside the housing 1, ensuring the assembly of all components inside the atomizer 10. On the other hand, the cooperation between the positioning support parts 63 and the positioning grooves 26 can also limit the installation position and angle of the mounting base 2 and the bottom cover 6, ensuring that the bottom cover 6, the mounting base 2, and the atomizing component 3 can be correctly assembled in the housing 1 according to the set position and angle.

[0099] Please refer to Figure 4. In some embodiments, the atomizer 10 further includes at least one ventilation channel 24. The ventilation channel 24 is disposed on the cavity wall of the mounting cavity 22. One end of each ventilation channel 24 is connected to the liquid storage cavity 4, and the other end is connected to the outside of the fixing base 2 and is in communication with the outside atmosphere.

[0100] The liquid storage chamber 4 of the atomizer 10 is a relatively sealed cavity structure. During use, as the atomizing matrix in the liquid storage chamber decreases, negative pressure will gradually be generated inside the liquid storage chamber, causing the atomizing matrix to be unable to flow out smoothly, which can easily lead to poor liquid supply and affect the user's inhalation experience.

[0101] The atomizer 10 provided in this application has at least one ventilation channel 24 on the fixed base 2, and the two ends of the ventilation channel 24 are respectively connected to the liquid storage chamber 4 and the outside atmosphere outside the fixed base 2. When a negative pressure occurs in the liquid storage chamber 4 during use, under the action of the internal and external pressure difference, the external air can be automatically replenished into the liquid storage chamber 4 through the ventilation channel 24, effectively regulating the pressure inside the liquid storage chamber 4, ensuring that the liquid storage chamber 4 can supply oil continuously and stably, solving the problem of poor oil supply caused by negative pressure, and further reducing the risk of leakage.

[0102] Referring to Figure 4, in some embodiments, the upper end of each ventilation channel 24 extends to the bottom of the guide surface 211 penetrating the liquid guide groove 21 and forms a ventilation outlet 2411, which connects to the liquid inlet channel 41 at the lower part of the liquid storage chamber 4. The lower end of each ventilation channel 24 extends to the bottom surface penetrating the bottom annular groove 23 and forms a ventilation inlet 2431, which connects to the air inlet chamber 5. During use, when the liquid storage chamber 4 generates negative pressure, the air in the air inlet chamber 5 can flow into the bottom annular groove 23 through the ventilation inlet 2431, and under the guidance of the ventilation channel 24, it is replenished into the liquid storage chamber 4 through the ventilation outlet 2411 to balance the internal and external air pressure of the liquid storage chamber 4, ensuring that the liquid storage chamber 4 can continuously and smoothly supply the atomizing matrix.

[0103] Please refer to Figure 4. In one specific embodiment, there are two ventilation channels 24, and the two ventilation channels 24 are arranged in a centrally symmetrical manner with the axial center line A of the atomizer 10 as the axis.

[0104] In actual use, the air in the air intake chamber 5 can be drawn into the bottom annular groove 23 through two symmetrically arranged air exchange inlets 2431, and is evenly distributed in the circumferential direction under the guidance of the bottom annular groove 23, which plays the role of annular air distribution, ensuring the consistency of air intake in each air exchange channel 24, and is conducive to the uniform liquid discharge from the liquid storage chamber 4.

[0105] Referring to Figure 4, in some embodiments, each ventilation channel 24 is formed by a recess in the cavity wall of the mounting cavity 22, so that the outer wall surface of the first liquid guiding member 31 can form a sealing effect on the groove of the ventilation channel 24 on the outside. This allows the liquid-absorbing effect of the first liquid guiding member 31 to absorb any atomized matrix that accidentally leaks into the ventilation channel 24, reducing the risk of atomized matrix in the liquid storage cavity 4 leaking out through the ventilation channel 24. In addition, the fact that the ventilation channel 24 is formed by a recess in the cavity wall of the mounting cavity 22 facilitates the integral molding of the fixing base 2, reducing the structural complexity and manufacturing cost of the fixing base 2.

[0106] Please refer to Figure 4. In some embodiments, each ventilation channel 24 extends in a tortuous manner along the cavity wall of the mounting cavity 22. Compared with a straight ventilation channel, the tortuous extension structure design can reduce the risk of the atomized matrix in the liquid storage cavity 4 leaking directly through the ventilation channel 24.

[0107] Referring to Figure 4, in some embodiments, each ventilation channel 24 includes a first section 241, a second section 242, and a third section 243 connected in sequence. The first section 241 extends axially along the mounting cavity 22, the second section 242 extends circumferentially along the cavity wall of the mounting cavity 22, and the third section 243 extends axially along the mounting cavity. The axis of the first section 241 and the axis of the third section 243 are not on the same straight line, ensuring that each ventilation channel 24 can extend in a tortuous manner along the cavity wall of the mounting cavity 22.

[0108] In one specific embodiment, the first section 241 of the ventilation channel 24 is formed on the cavity wall of the mounting cavity 22 abutting against the first liquid guide 31, and extends linearly along the axial direction of the mounting cavity 22 to connect to the corresponding ventilation outlet 2411; the second section 242 of the ventilation channel 24 is formed on the upper end face of the fixed platform 221 facing the air guide tube 12, and extends circumferentially along the cavity wall of the mounting cavity 22 in an arc shape; the third section 243 of the ventilation passage 24 is formed on the arc-shaped inner wall of the fixed platform 221, and extends linearly along the axial direction of the mounting cavity 22 to connect to the corresponding ventilation inlet 2431. In this way, the path of each ventilation channel 24 on the cavity wall of the mounting cavity 22 is arranged in a tortuous manner that is approximately "Z" shaped, which can minimize the risk of leakage of the ventilation channel 24 and ensure that the atomizer 10 will not easily leak during transportation, shelf life, and use.

[0109] In actual use, the atomizing matrix in the storage chamber 4 flows downward under the action of gravity into the liquid inlet channel 41 at its lower part, and is evenly distributed to the first storage component 31 under the guidance of the liquid guide groove 21, which plays the role of annular liquid distribution. Together with at least one ventilation channel 24, it controls the continuity and consistency of the liquid output of the atomizing matrix in the storage chamber 4, realizes the oil supply balance, and thus ensures the uniformity of the aerosol generated by atomization, which can significantly improve the quality of the atomized gas and enhance the user's inhalation experience.

[0110] Please refer to Figures 2 and 8. In some embodiments, the atomizer 10 further includes at least two seals 8, which are respectively sealed between the outer wall of the fixing base 2 and the inner wall of the housing 1, and between the outer wall of the bottom cover 6 and the inner wall of the housing 1.

[0111] Taking two seals 8 as an example, they are designated as the first seal 81 and the second seal 82. Preferably, both the first seal 81 and the second seal 82 are sealing rings.

[0112] Please refer to Figures 5 and 7. Correspondingly, the outer wall of the fixing base 2 is provided with a first sealing groove 29 circumferentially, and the inner wall of the bottom cover 6 is provided with a second sealing groove 65 circumferentially. A first sealing element 81 is fitted into the first sealing groove 29, and a second sealing element 82 is fitted into the second sealing groove 65. After assembly, the first sealing element 81 seals the gap between the outer wall of the fixing base 2 and the inner wall of the housing 1, and the second sealing element 82 seals the gap between the outer wall of the bottom cover 6 and the inner wall of the housing 1.

[0113] The atomizer 10 provided in this application has a first sealing element 81 and a second sealing element 82 added to the outer walls of the fixing base 2 and the bottom cover 6, respectively, which can further improve the overall sealing performance of the atomizer 10, prevent leakage after the atomizer 10 has been placed for a long time, and achieve a better sealing effect.

[0114] In some embodiments, the bottom cover 6 and the housing 1 are preferably provided with a snap-fit ​​fixing structure (not shown) that engages with each other. The bottom cover 6 is detachably connected to the bottom of the housing 1 and abuts against the fixing seat 2 through the snap-fit ​​fixing structure. The structure is simple and facilitates the disassembly and assembly of the atomizer 10.

[0115] Please refer to Figures 1, 3, and 7. The snap-fit ​​fixing structure includes at least one set of engaging snap-fit ​​parts 66 and snap-fit ​​grooves 17. In one specific embodiment, the snap-fit ​​parts 66 are symmetrically arranged on the outer wall of the bottom cover 6, and the snap-fit ​​grooves 17 are symmetrically arranged on the bottom outer wall of the housing 1 near the mounting slot 14, engaging with the snap-fit ​​parts 66 one-to-one. When the bottom cover 6 is installed in the mounting slot 14, the snap-fit ​​parts 66 are respectively snapped and fixed in the corresponding snap-fit ​​grooves 17 to fix the bottom cover 6 on the housing 1 and limit the fixing seat 2 and the atomizing component 3.

[0116] Referring to Figure 10, in some embodiments of this application, an atomizing device 100 is provided, which includes a power supply device 20 and an atomizer 10 as described in any of the above. The atomizer 10 is detachably connected to and electrically connected to the power supply device 20.

[0117] Referring to Figure 10, in one specific embodiment, the power supply device 20 includes a housing 9, on which a mounting slot 91 and a power supply module 92 are provided. The atomizer 10 is detachably connected to the mounting slot 91 and electrically connected to the power supply module 92, so as to supply power to the heating element 34 of the atomizing assembly 3 through the power supply module 92. After the atomizing matrix in the atomizer 10 is exhausted, a new atomizer 10 can be installed on the mounting slot 91 of the power supply device 20, realizing the reuse of the power supply device 20.

[0118] Referring to Figure 10, in some embodiments, the power supply device 20 further includes two electrical terminals 93 disposed on the housing 9 and electrically connected to the power supply module 92. The electrical terminals 93 include a positive electrical terminal 931 and a negative electrical terminal 932, and the electrical terminals 93 are at least partially located within the mounting groove 91 and at least partially extend to be electrically connected to the power supply module 92.

[0119] When the atomizer 10 is installed on the mounting slot 91, the positive electrode 711 on the bottom cover 6 abuts against the positive terminal 931, and the negative terminal 932 on the bottom cover 6 abuts against the negative terminal 932, so that the power supply module 92 is electrically connected to the heating element 34 through the terminal 93 and the conductive element 7, so as to supply power to the heating element 34.

[0120] The power supply device 20 is also provided with an air intake channel 94. One end of the air intake channel 94 extends to the bottom surface of the through mounting groove 91 and forms an airflow outlet 941. The other end of the air intake channel 94 extends to the bottom of the through housing 9 and forms an airflow inlet 942.

[0121] In actual use, air from outside the atomizing device 100 enters the air intake channel 94 through the airflow inlet 942, then enters the mounting slot 91 through the airflow outlet 941, and then enters the atomizer 10 through the air inlet 61. The airflow carries away the aerosol generated by heating in the atomizing air passage 331 of the second liquid guide 33 and mixes it to form atomized gas. The atomized gas is finally sent to the air outlet 15 through the air guide pipe 12 for the user to inhale.
