They will have a complete understanding of the related operations based on the description in the specification and the general technical knowledge in the art.

[0045] In addition, features described in the specification, operations or characteristics can be combined in any appropriate manner in various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0046] Referring to Figures 1-2 , Figures 8-9 In some embodiments of the present application, an atomizer 10 is provided. The atomizer 10 comprises a housing 1, a fixed seat 2, an atomization assembly 3, and the fixed seat 2 is fixed in the housing 1. The fixed seat 2 is preferably sealed and embedded in the housing 1 in an interference fit, and the fixed seat 2 is provided with a mounting cavity 22 (as shown in Figure 9 ) in communication with a liquid storage cavity 4 in the axial direction.

[0047] Referring to Figure 2 and Figure 9 , the atomization assembly 3 is received in the mounting cavity 22 and is used to heat and atomize the substrate and generate aerosol. The atomization assembly 3 comprises a liquid guide assembly (not shown) and a heating element 34. The liquid guide assembly comprises a first liquid guide 31 and a second liquid guide 33, wherein the second liquid guide 33 is isolated from the liquid storage cavity 4, and the side of the second liquid guide 33 opposite to the first liquid guide 31 forms an atomization air passage 331. The atomization air passage 331 preferably extends through both ends of the second liquid guide 33 in the axial direction, and the heating element is received in the atomization air passage 331 and at least partially abuts the inner wall surface of the second liquid guide 33, for atomizing the atomization substrate transmitted by the second liquid guide. The first liquid guide 31 is sleeved on the periphery of the second liquid guide 33 and is in fluid communication with each other, and at least part of the first liquid guide 31 is in communication with the liquid storage cavity 4, for absorbing the atomization substrate in the liquid storage cavity 4 and transmitting it to the second liquid guide 33, so that the atomization substrate can be heated by the heating element 34 at the atomization air passage 331 of the second liquid guide 33 to generate aerosol and realize atomization and smoking, for the user to smoke.

[0048] The density of the first liquid guide 31 is greater than the density of the second liquid guide 33.

[0049] In the atomizer 10 provided in the present application, the liquid guide component of the atomizing assembly 3 utilizes the first liquid guide member 31 to absorb the atomized matrix and transmit it to the second liquid guide member 33, playing the role of absorbing liquid, storing liquid, and guiding liquid, thereby ensuring the continuous and stable supply of the atomized matrix. Moreover, the density of the first liquid guide member 31 is greater than the density of the second liquid guide member 33, so that the first liquid guide member 31 has a greater density than the second liquid guide member 33. In addition to the functions of absorbing, storing and transmitting the atomized matrix, it also has a better liquid locking effect, can store a sufficient amount of atomized matrix, and effectively control the rate of transmitting the atomized matrix to the second liquid guide member 33, thereby ensuring the continuous and stable supply of the atomized matrix during the suction use process, and effectively avoiding the problem of atomized matrix leakage caused by long-term storage on the shelf and vibration during transportation, thereby improving the user experience.

[0050] See also Figure 4 and Figure 9 In some embodiments, a liquid guide groove 21 is further provided on the side of the fixing base 2 facing the liquid storage chamber 4. A first liquid guide member 31 is fixed in the fixing base 2 and extends into the liquid guide groove 21 from the upper end thereof toward the liquid storage chamber 4. The housing 1 and the wall of the liquid guide groove 21 jointly define a liquid inlet channel 41, and the liquid guide assembly at least blocks the liquid inlet channel 41.

[0051] The liquid inlet channel 41 is preferably formed at the lower end of the liquid storage chamber 4 in the direction of gravity, and can drain the atomized matrix in the liquid storage chamber 4 to the first liquid guide part 31 of the liquid guide component, thereby playing the role of drainage and flow limiting, reducing the contact area between the first liquid guide part 31 and the liquid storage chamber 4, thereby controlling the liquid absorption efficiency and liquid absorption amount of the first liquid guide part 31, so that the first liquid guide part 31 can achieve the consistency of liquid supply balance in the transmission of the atomized matrix, and prevent the liquid conduction imbalance of the atomization component 3 caused by the transmission rate of the second liquid guide part 33 for the atomized matrix being greater than the consumption rate of the atomized matrix during use, thereby causing leakage problems, significantly reducing the risk of leakage.

[0052] See also Figure 4 and Figure 9 In one embodiment, the liquid guide groove 21 is disposed at the upper end of the fixing base 2 facing the liquid storage chamber 4 and is axially recessed into the fixing base 2 until it communicates with the mounting chamber 22. The inner diameter of the liquid guide groove 21 is larger than the inner diameter of the mounting chamber 22, so that the liquid guide groove 21 surrounds the end of the mounting chamber 22 facing the liquid storage chamber 4. The first liquid guide member 31 is preferably configured as a hollow cylindrical tubular structure, whose outer diameter matches the inner diameter of the mounting chamber 22 and is smaller than the inner diameter of the liquid guide groove 21, so that the upper end of the first liquid guide member 31 at least partially extends to and blocks the liquid inlet channel 41, thereby evenly directing the atomized substrate to the first liquid guide member 31. The liquid absorption amount of the first liquid guide member 31 can be controlled by the channel capacity of the surrounding liquid inlet channel 41.

[0053] The upper end of the first liquid guide member 31 extends into the liquid guide groove 21 and is connected to the liquid inlet channel 41. The lower part of the first liquid guide member 31 is inserted and fixed in the installation cavity 22 in an interference fit manner, so that at least part of the lower outer wall surface of the first liquid guide member 31 can be sealed against the cavity wall of the installation cavity 22 and form a good seal. The second liquid guide member 33 is accommodated in the first liquid guide member 31 and forms a fluid connection with the first liquid guide member 31. Combined with the design that the density of the first liquid guide member 31 is greater than the density of the second liquid guide member 33, the first liquid guide member 31 can better lock the atomized matrix, effectively avoiding the atomized matrix in the liquid inlet channel 41 from leaking out through the gap between the outer wall surface of the first liquid guide member 31 and the cavity wall of the installation cavity 22, further improving the sealing performance of the atomizer 10 of the present application.

[0054] In some other embodiments, the liquid guide groove 21 can also be set to be multiple, formed by a radial inward concave at the cavity wall of one end of the installation cavity 22 opening toward the liquid storage cavity 4, and the multiple liquid guide grooves 21 are preferably distributed in a centrally symmetrical manner with the axis of the installation cavity 22 as the center, so that the multiple liquid guide grooves 21 are circumferentially distributed at the end of the installation cavity 22 opening toward the liquid storage cavity 4, so that a plurality of distributed liquid inlet channels 41 distributed circumferentially at the upper end of the first liquid guide member 31 are defined between the shell 1 and the groove walls of the multiple liquid guide grooves 21. The atomized matrix can be drained from different positions to the first liquid guide member 31 through the distributed multiple liquid inlet channels 41, and the liquid absorption amount and liquid distribution effect of the liquid guide component per unit time can be controlled by adjusting the setting number, groove capacity, setting position, etc. of the liquid guide grooves 21, to prevent the atomized matrix in the liquid guide component from being oversaturated or unevenly distributed.

[0055] In some embodiments, the length of the first liquid guide member 31 extending into the liquid guide groove 21 accounts for a ratio of 1% to 40% of the overall length of the first liquid guide member 31. On the one hand, this ensures that the lower portion of the first liquid guide member 31 has sufficient length to be inserted into the mounting cavity 22 and has an interference fit with the mounting cavity 22, thereby ensuring the stability and reliability of the atomization assembly 3 being accommodated in the mounting cavity 22. On the other hand, it also ensures that less than half of the length of the upper end of the first liquid guide member 31 is directly immersed in the atomization matrix, reducing the contact area between the first liquid guide member 31 and the atomization matrix, enabling the first liquid guide member 31 to achieve consistency in the transmission of the atomization matrix and the balance of liquid supply, thereby preventing the first liquid guide member 31 from being oversaturated and leaking, further improving the sealing performance of the atomizer 10 of the present application, and reducing the risk of leakage.

[0056] See also Figure 9In some embodiments, a guide surface 211 is provided on the side of the liquid-guiding groove 21 facing the liquid-storing chamber 4. The guide surface 211 extends obliquely from the end of the fixing base 2 proximal to the liquid-storing chamber 4 toward the lower end of the fixing base 2 facing away from the liquid-storing chamber 4, and gradually converges to the end where the first liquid-guiding member 31 extends into the liquid-guiding groove 21, thereby forming a wedge-shaped vertical cross-section of the liquid-guiding groove 21. The guide surface 211 may be a flat surface or a curved surface, which is not limited in this application; it is sufficient that the guide surface 211 guides the atomized substrate to the first liquid-guiding member 31.

[0057] See also Figure 9 In one embodiment, the bottom wall of the liquid guide groove 21 is configured such that the inner diameter gradually decreases from the upper end facing the liquid storage chamber 4 to the lower end facing away from the liquid storage chamber 4, forming a funnel-shaped annular guide surface 211. This allows the atomized matrix in the liquid inlet channel 41 at the bottom of the liquid storage chamber 4 to be guided by the guide surface 211 and flow evenly toward the upper end of the first liquid guide member 31 extending into the liquid guide groove 21, further improving the consistency of the liquid discharge from the liquid storage chamber 4 and enhancing the heating and atomization effect of the atomizer assembly 3 on the atomized matrix. In addition, the retractable structural design of the bottom wall of the liquid guide groove 21 also facilitates the assembly of the atomizer assembly 3 in the axial direction, through the liquid guide groove 21, into the mounting cavity 22, with a higher fault tolerance rate, which is conducive to the automated assembly of the atomizer 10.

[0058] The upper end of the first liquid guide member 31 of the liquid guide assembly of the present application directly absorbs the atomized matrix in the liquid inlet channel 41 in the annular liquid guide groove 21, playing the role of absorbing, storing and guiding liquid. Combined with the structural design of the annular guide surface 211 of the liquid guide groove 21, the atomized matrix can be evenly transferred to the first liquid guide member 31 in all directions. The first liquid guide member 31 and the second liquid guide member 33 are fluidically connected to each other and transfer the atomized matrix by utilizing the capillary phenomenon between the micropores of the material itself, so that the atomized matrix on the first liquid guide member 31 can be evenly transferred to the second liquid guide member 33, and then heated by the heating element 34 housed in the atomizing airway 331, ensuring that the atomized matrix can be evenly heated to atomize, ensuring the consistency of taste during inhalation, and avoiding the problem of sticking the core due to uneven distribution of the atomized matrix. In addition, the atomizer 10 of the present application optimizes the length of the first liquid guiding member 31 extending into the liquid guiding groove 21, and the density of the first liquid guiding member 31 is set to be greater than the density of the second liquid guiding member 33, which can further control the liquid absorption amount of the liquid guiding component and the liquid guiding efficiency of the liquid guiding component, ensuring the balance of supply and demand of the atomized matrix while having a better liquid locking effect, further reducing the risk of leakage of the atomizer 10.

[0059] In addition, the first liquid-guiding member 31 itself can store a certain amount of atomized matrix, which increases the overall liquid storage capacity of the liquid-guiding component. The atomized matrix can be quickly transferred to the second liquid-guiding member 33 during the suction process, ensuring the continuity of oil supply and the consistency of the atomized gas concentration in each puff, thereby improving the user's smoking experience.

[0060] See also Figures 1-3 The shell 1 is commonly known as an oil cup in the art. In some embodiments, the shell 1 is preferably made of PP plastic material and has an internal accommodating cavity 11. The shell 1 is vertically arranged along the direction of gravity. The upper end of the shell 1 is provided with a suction nozzle 13 and the lower end is provided with a mounting notch 14. The suction nozzle 13 is formed with an air outlet 15 on the shell 1 (such as Figure 2 As shown in FIG, the upper end of the accommodating cavity 11 is connected to the outside through the air outlet 15, and the lower end of the accommodating cavity 11 is connected to the outside through the installation slot 14.

[0061] See also Figures 8-9 The housing 1 is also provided with an air guide tube 12 that communicates with the outside world through the air outlet 15. The first liquid guide member 31 and the second liquid guide member 33 are both tubular. The air guide tube 12 extends downward into the liquid guide groove 21 of the fixed base 2 and abuts against the first liquid guide member 31. The outlet end of the atomizing air channel 331 is connected to the air guide tube 12 and communicates with the outside world through the air outlet 15. The outer wall of the air guide tube 12, the fixed base 2, the upper end of the first liquid guide member 31 extending into the liquid guide groove 21, and the inner wall of the housing 1 collectively define the liquid storage chamber 4.

[0062] Please refer to 4. Figures 8-9 , in coordination with it, a fixing platform 221 is provided on the cavity wall of the installation cavity away from the air guide tube 12, and the two ends of the first liquid guiding member 31 in the axial direction are fixedly clamped between the fixing platform 221 and the air guide tube 12, and the outer wall surface of the first liquid guiding member 31 is at least partially sealed against the cavity wall of the installation cavity 22, so as to limit the first liquid guiding member 31 through the fixing seat 2 and the air guide tube 12.

[0063] The fixing base 2 is preferably also made of PP plastic material. During assembly, the lower end of the atomizer assembly 3 can be axially inserted into the mounting cavity 22 of the fixing base 2, so that the atomizer assembly 3 as a whole is assembled with the fixing base 2 to form a vertical combination, and then the formed vertical combination is axially inserted into the shell 1 through the mounting groove 14, so that the upper end of the first liquid guide member 31 abuts against the air guide tube 12, and the lower end of the first liquid guide member 31 abuts against the fixing platform 221, so that the outer wall of the fixing base 2 is sealed and embedded in the inner wall of the accommodating cavity 11 of the shell 1 in an interference fit manner, and a good seal is formed between the fixing base 2 and the shell 1 to prevent leakage.

[0064] The air guide tube 12 of the atomizer 10 of the present application is configured to extend into the liquid guide groove 21 of the fixed seat 2, and cooperates with the installation cavity 22 to further limit the axial length of the first liquid guide member 31, thereby preventing the upper end of the first liquid guide member 31 from extending out of the liquid guide groove 21 and being excessively immersed in the liquid storage cavity 4, thereby avoiding the first liquid guide member 31 from being oversaturated due to adsorption of excessive atomized matrix, and further reducing the risk of leakage of the atomizer 10.

[0065] In addition, the fixed seat 2 in the atomizer 10 of the present application is fixedly assembled with the shell 1 in a manner of interference fit, which can realize good sealing between the outer wall of the fixed seat 2 and the inner wall of the shell 1, ensure that the atomizer 10 is not easy to leak liquid during transportation, shelf period and use, and can save the setting of the silica gel sealing ring, thereby avoiding the problem of aroma attenuation caused by the direct contact of the atomization substrate in the liquid storage cavity 4 with the silica gel material.

[0066] Please refer to Figure 3 , Figure 8 In some embodiments, the cross-sectional shape of the containing cavity 11 of the shell 1 on the horizontal plane is preferably circular, and the air guide pipe 12 extends axially along the axis of the containing cavity 11 from the air outlet 15 to one side of the mounting slot 14.

[0067] Please refer to Figure 4 , Figure 9 In cooperation, the fixed seat 2 is provided in a cylindrical structure that matches the inner wall of the containing cavity 11 of the shell 1, and the mounting cavity 22 is preferably provided to extend along the axial center line A of the atomizer 10 and coaxially with the containing cavity 11. In this way, the shell 1, the fixed seat 2, the atomization assembly 3 and other components of the atomizer 10 of the present application can be automatically assembled in an axial stacking manner, which has the advantages of simple structure, fewer components and convenient installation compared with the existing design, and can significantly reduce the production cost of the atomizer 10.

[0068] Please refer to Figure 4 , Figure 5 and Figure 9 In some embodiments, the end of the fixed seat 2 away from the air guide pipe 12 is provided with a ventilation hole 251 that penetrates through, which is preferably provided at the center of the bottom of the mounting cavity 22 to communicate the space outside the fixed seat 2 with the mounting cavity 22, and the ventilation hole 251 is in communication with the atomization air passage 331 in the second liquid guide 33, so that the ambient air of the atomizer 10 can enter the atomization air passage 331 through the ventilation hole 251 and mix with the aerosol generated by atomization to form atomization gas.

[0069] Please refer to Figure 4 and Figure 9 In some embodiments, the fixed platform 221 is preferably provided around the lower cavity wall of the mounting cavity 22 and is connected with the bottom surface of the mounting cavity 22, so that the inner side of the fixed platform 221 forms an annular inner wall, and the ventilation hole 251 is provided at the center of the inner wall of the fixed platform 221.

[0070] In other embodiments, the fixed platform 221 can also be provided in a plurality of circumferential distribution on the lower cavity wall of the mounting cavity 22, and the inner sides of the plurality of fixed platforms 221 collectively form a discontinuous annular inner wall structure, and the ventilation hole 251 is provided at the center of the inner wall of the fixed platform 221.

[0071] See also Figure 2 and Figure 9 In some embodiments, the atomizer assembly 3 further includes an atomizer tube 32. The upper end of the atomizer tube 32 facing the liquid storage chamber 4 is plugged into the air guide tube 12 and connected to the air outlet 15. The lower end of the atomizer tube 32 facing away from the liquid storage chamber 4 is plugged into the installation cavity 22 and connected to the vent 251. At least one liquid inlet 321 is provided through the wall of the atomizer tube 32.

[0072] See also Figure 6 、 Figure 8 and Figure 9 After the atomizing assembly 3 is assembled, the second liquid-guiding member 33 is housed in the atomizing tube 32, and at least partially closes the liquid inlet 321 from the inside; the first liquid-guiding member 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 in the second liquid-guiding member 33 and electrically connected to an external power supply. During actual use, the atomized matrix adsorbed on the first liquid-guiding member 31 is transferred to the second liquid-guiding member 33 via the liquid inlet 321, thereby achieving fluid communication between the first liquid-guiding member 31 and the second liquid-guiding member 33. The heating element 34 generates heat under the drive of electricity, thereby heating the atomized matrix transferred to the inner wall surface of the second liquid-guiding member 33 and within the operating range of the heating element 34 until it is atomized and generates an aerosol.

[0073] In one 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 in an interference fit manner, and the lower outer wall of the atomizing tube 32 is at least partially sealed 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 a plug-in 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 plugged and fixed to the annular inner wall of the fixing platform 221, and the upper end of the atomizing tube 32 is plugged and fixed to the plug-in groove at the lower end of the air guide tube 12.

[0074] After being plugged in and fixed, the outer wall surface of the atomizing tube 32, the cavity wall of the mounting cavity 22, and the upper end surface of the fixing platform 221 facing the liquid storage cavity 4 jointly define a limiting space for fixing and clamping the lower part of the first liquid guiding member 31, ensuring that the atomizing assembly 3 as a whole can be stably and reliably plugged in and fixed in the fixing seat 2.

[0075] Preferably, there are multiple liquid inlets 321, which are symmetrically arranged or distributed around the axis of the atomizing tube 32. The atomized matrix can be evenly delivered to the second liquid guiding member 33 through the multiple liquid inlets 321, thereby ensuring the uniformity of liquid guiding of the second liquid guiding member 33.

[0076] During actual use, the user draws in the mouthpiece 13 at the upper end of the shell 1 with their mouth, so that negative pressure is generated inside the shell 1. The outside air enters the atomizing tube 32 through the vent 251 and flows into the atomizing airway 331 in the second liquid-guiding member 33. At the same time, the atomized matrix in the liquid storage chamber 4 flows to the first liquid-guiding member 31 along the guide surface 211 of the liquid-guiding groove 21 under the guidance of the liquid inlet channel 41, and is then adsorbed by the first liquid-guiding member 31 and transferred to the second liquid-guiding member 33 through the liquid inlet 321. It is then transferred to the inner wall surface of the second liquid-guiding member 33 and then heated by the heating element 34 to atomize and generate an aerosol. The generated aerosol mixes with the airflow in the atomizing airway 331 to form atomized gas. The atomized gas is finally discharged through the air outlet 15 under the transmission of the air guide tube 12 for the user to inhale.

[0077] See also Figure 4 and Figure 9 In some embodiments, the fixing base 2 is further provided with a vent portion 25. The vent portion 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 fixing platform 221. The bottom of the vent portion 25 penetrates the bottom end of the fixing base 2 facing away from the air guide tube 12 and forms the aforementioned vent hole 251. On the one hand, the vent portion 25 can guide the air entering through the vent hole 251 into the atomizing tube 32 and deliver it to the atomizing air channel 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 fixing platform 221. During use, a certain amount of atomized matrix can be accumulated in the bottom annular groove 23, which can prevent the atomized matrix that has leaked into the mounting cavity 22 from leaking directly through the vent hole 251.

[0078] In addition, the air entering the atomizer tube 32 through the vent 25 can flow downward in a circuitous manner to the bottom annular groove 23 and accumulate, reducing the risk of oil explosion during use, and also increasing the airflow supply in the atomizer tube 32, increasing the concentration of atomized gas in each puff, and improving the user's smoking experience.

[0079] See also Figures 1-3 、 Figure 8 In some embodiments, the atomizer 10 further includes a bottom cover 6, which is preferably snap-fitted and fixed to the bottom mounting notch 14 of the shell 1 facing away from the air guide tube 12, and at least a portion of the bottom cover 6 abuts against the fixing seat 2, so as to limit the fixing seat 2 through the bottom cover 6 and prevent the fixing seat 2 from loosening from the inner wall of the shell 1.

[0080] See also Figures 8-9 After the bottom cover 6 is snap-fitted and fixed in the mounting notch 14 , it can define an air inlet cavity 5 between the fixing base 2 and the inner wall of the shell 1 , and the vent hole 251 is connected to the air inlet cavity 5 .

[0081] See also Figure 7 and Figure 9The bottom cover 6 is provided with at least two air inlet holes 621 connecting the air inlet cavity 5 with the outside atmosphere.

[0082] During assembly, the atomizer assembly 3 and the fixing base 2 can be assembled to form a vertical assembly first, and then the formed vertical assembly can be axially inserted into the housing 1 through the installation slot 14. Finally, the bottom cover 6 can be axially installed on the installation slot 14 at the bottom of the housing 1, and the fixing base 2 can be pressed against the bottom cover 6 to limit and fix the fixing base 2 and the atomizer assembly 3 in the housing 1.

[0083] The atomizer 10 provided in the present application is assembled by a housing 1, a fixing base 2, an atomizing assembly 3 and a bottom cover 6. The overall structure is relatively simple and has few components. The components can be stacked and assembled in the axial direction, which facilitates automated assembly and helps reduce production costs.

[0084] During actual use, the user draws on the nozzle 13 to generate negative pressure inside the shell 1. Under the action of the pressure difference, the air outside the shell 1 flows into the air inlet cavity 5 through at least two air inlet holes 621 on the bottom cover 6. The air in the air inlet cavity 5 then enters the atomizer tube 32 through the vent hole 251.

[0085] See also Figure 9 In some embodiments, the axes of at least two air inlet holes 621 are offset from the axis of the vent hole 251. This prevents air from the outside atmosphere from flowing directly into the vent hole 251 through the air inlet holes 621, instead forcing some air to flow circuitously within the air inlet cavity 5. This further reduces the risk of oil frying and uneven atomization caused by direct airflow during use. Furthermore, this offset arrangement prevents condensed air or atomized substrate leaking from the mounting cavity 22 from dripping directly into the air inlet hole 621 through the vent hole 251, potentially causing leakage.

[0086] See also Figures 7-9 In some embodiments, the bottom cover 6 is further provided with an air inlet portion 62, which is a hollow tubular structure, extending axially from the bottom surface of the bottom cover 6 to the air inlet cavity 5, and the bottom of the air inlet portion 62 passes through the bottom end of the bottom cover 6 facing away from the air guide tube 12, and forms an air inlet 61 (such as Figure 10 ). The upper end portion of the air inlet portion 62 facing the fixed base 2 is at least partially closed and has a plurality of branch pipe portions (not shown) extending axially therefrom. The branch pipe portions are arranged centrally and symmetrically about the axis of the air inlet portion 62. The upper end of each branch pipe portion is axially penetrated by the aforementioned air inlet hole 621.

[0087] During use, air from the outside atmosphere first enters the air inlet portion 62 through the air inlet 61, flows through the branch pipes to the air inlet holes 621, and then flows into the air inlet cavity 5. It then flows through the vent holes 251 and the vent portion 25 and enters the bottom annular groove 23. Because the axes of the air inlet holes 621 are misaligned with the axis of the vent hole 251, the airflow discharged from the air inlet holes 621 is obstructed by the bottom end surface of the fixing base 2, forming a circuitous airflow in the air inlet cavity 5, further reducing the risk of oil explosion during use of the atomizer 10.

[0088] See also Figure 2 and Figure 8 In some embodiments, the atomizer 10 further includes a first closure member 64 and a second closure member 16. The first closure member 64 is detachably mounted on the air inlet 61 of the bottom cover 6 and closes the air inlet end of each air inlet hole 621, thereby closing the air inlet portion 62. The second closure member 16 is detachably mounted on the air outlet 15 of the suction nozzle 13 and closes the air outlet end of the air guide tube 12. In a non-use state, the air inlet 61 and the air outlet 15 of the atomizer 10 can be blocked by the first closure member 64 and the second closure member 16. On the one hand, this can prevent dust from entering the air inlet 61 and the air outlet 15. On the other hand, this can seal the atomizer 10 to maintain the air pressure balance inside and outside the atomizer 10, prevent the atomized matrix in the liquid storage chamber 4 from leaking out, and ensure that liquid will not leak easily during transportation, shelf life, and use.

[0089] See also Figure 2 and Figure 6 In some embodiments, the heating element 34 includes a heating mesh 341 and an electrode pin 342. The heating mesh 341 is preferably wound into a cylindrical structure and accommodated in the second liquid-conducting member 33, and the cylindrical heating mesh 341 is attached to the inner wall surface of the second liquid-conducting member 33.

[0090] See also Figures 7-9 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 toward the end away from the air duct 12 and abuts against the end of the fixing base 2 in the air inlet cavity 5 .

[0091] Correspondingly, a conductive member 7 is provided on the bottom cover 6. One end of the conductive member 7 extends into the air inlet cavity 5 and at least partially abuts the electrode pin 342 to establish an electrical connection with the heating mesh 341. The other end of the conductive member 7 extends out of the bottom cover 6, facing away from the fixing base 2, and abuts the bottom surface of the bottom cover 6 facing away from the housing 1, forming an electrode sheet (not shown) to facilitate connection to an external power source and power the heating element 34.

[0092] See also Figures 6-8In a specific embodiment, the heating element 34 has a heating mesh 341, and the electrode pin 342 includes a positive electrode pin 3421 and a negative electrode pin 3422, which are not in contact with each other.

[0093] Correspondingly, the conductive element 7 includes a positive conductive element 71 and a negative conductive element 72. The upper end of the positive conductive element 71 abuts against the positive electrode pin 3421, and the lower end of the positive conductive element 71 is attached to the bottom surface of the bottom cover 6 and forms a positive electrode sheet 711. The upper end of the negative conductive element 72 abuts against the negative electrode pin 3422, and the lower end of the negative conductive element 72 is attached to the bottom surface of the bottom cover 6 and forms a negative electrode sheet 721.

[0094] Please refer to Figures 4-5 The bottom of the fixed seat 2 is also provided with two pin through holes 27 for the positive electrode pin 3421 and the negative electrode pin 3422 to extend out of the installation cavity 22, and the two pin through holes 27 both pass through the bottom ring groove 23. The bottom end surface of the fixed seat 2 facing away from the air duct 12 is also provided with two concave pin positioning grooves 28 connected with the corresponding pin through holes 27. After assembly, the positive electrode pin 3421 and the negative electrode pin 3422 of the heating element 34 extend out of the installation cavity 22 through the corresponding pin through holes 27 and are inserted into the corresponding pin positioning grooves 28 after being bent. 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 electrode pin 3421, and 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 electrode pin 3422, so as to establish an electrical connection relationship between the conductive element 7 and the heating element 34.

[0095] Please refer to Figures 7-9 In some embodiments, the bottom of the bottom cover 6 is also provided with two positioning support portions 63 extending axially to one end of the fixed seat 2, which are symmetrically arranged with the axial center line A of the atomizer 10 as the axis, and are distributed on both sides of the air inlet portion 62, and both of the positioning support portions 63 extend beyond the air inlet hole 621.

[0096] Please refer to Figure 5Correspondingly, the bottom end of the fixing base 2, facing away from the air guide tube 12, is provided with two inwardly concave positioning grooves 26. After assembly, the two positioning support portions 63 on the bottom cover 6 are respectively inserted into the corresponding positioning grooves 26 and stopped at the end surfaces of the positioning grooves 26. On the one hand, the positioning support portions 63 can limit and fix the combination of the fixing base 2 and the atomizer assembly 3 inside the housing 1, ensuring the combined assembly of the various components inside the atomizer 10. On the other hand, the cooperation between the positioning support portions 63 and the positioning grooves 26 can also achieve the definition of the installation position and installation angle of the fixing base 2 and the bottom cover 6, ensuring that the bottom cover 6, the fixing base 2 and the atomizer assembly 3 can be correctly assembled in the housing 1 according to the set position and angle.

[0097] See also Figure 4 In some embodiments, the atomizer 10 further includes at least one ventilation channel 24, which is provided 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 seat 2 and is connected to the outside atmosphere.

[0098] The liquid storage chamber 4 of the atomizer 10 is a relatively sealed cavity structure. During use, as the atomized matrix in the liquid storage chamber continues to decrease, negative pressure will gradually be generated inside the liquid storage chamber, resulting in the atomized matrix not being able to flow out smoothly, which is prone to problems with liquid supply, affecting the user's smoking experience.

[0099] The atomizer 10 provided in the present application is provided with at least one ventilation channel 24 on the fixing base 2, and the two ends of the ventilation channel 24 are respectively connected to the liquid storage chamber 4 and the external atmosphere outside the fixing base 2. When negative pressure appears in the liquid storage chamber 4 during use, under the action of the internal and external pressure difference, external air can be automatically replenished into the liquid storage chamber 4 through the ventilation channel 24, effectively adjusting the pressure inside the liquid storage chamber 4, ensuring that the liquid storage chamber 4 can continuously and stably supply oil, solving the problem of poor oil supply caused by negative pressure, and further reducing the risk of leakage.

[0100] See also Figure 4 In some embodiments, the upper end of each ventilation channel 24 extends to the bottom of the guide surface 211 that passes through the liquid guide groove 21 and forms a ventilation outlet 2411. This ventilation outlet 2411 is connected to the liquid inlet channel 41 at the bottom of the liquid storage chamber 4. The lower end of each ventilation channel 24 extends to the bottom surface of the bottom annular groove 23 and forms a ventilation inlet 2431. This ventilation inlet 2431 is connected to the air inlet chamber 5. During use, when the liquid storage chamber 4 generates a 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, be replenished into the liquid storage chamber 4 through the ventilation outlet 2411, thereby balancing the internal and external air pressures of the liquid storage chamber 4 and ensuring that the liquid storage chamber 4 can continuously and smoothly supply the aerosolized substrate.

[0101] See alsoFigure 4 In one embodiment, there are two ventilation channels 24 , and the two ventilation channels 24 are arranged symmetrically with respect to the axial center line A of the atomizer 10 .

[0102] During actual use, the air in the air intake chamber 5 can flow into the bottom annular groove 23 through two symmetrically arranged ventilation inlets 2431, and be evenly distributed in the circumferential direction under the guidance of the bottom annular groove 23, playing the role of annular air distribution, ensuring the consistency of air intake in each ventilation channel 24, which is conducive to uniform liquid discharge from the liquid storage chamber 4.

[0103] See also Figure 4 In some embodiments, each ventilation channel 24 is formed by a concave portion of the wall of the mounting cavity 22, so that the outer wall of the first liquid guide 31 can seal the notch of the ventilation channel 24 from the outside. The first liquid guide 31 can absorb the atomized matrix that accidentally leaks into the ventilation channel 24, thereby reducing the risk of the atomized matrix in the liquid storage chamber 4 leaking out through the ventilation channel 24. Furthermore, the ventilation channel 24 formed by the concave portion of the wall of the mounting cavity 22 facilitates the integral molding of the fixing base 2, thereby reducing the structural complexity and manufacturing cost of the fixing base 2.

[0104] See also Figure 4 In some embodiments, each ventilation channel 24 is arranged to extend in a zigzag manner along the cavity wall of the installation cavity 22. Compared with a straight ventilation channel, the zigzag extension structural design can reduce the risk of the atomized matrix in the liquid storage cavity 4 directly leaking out through the ventilation channel 24.

[0105] See also 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, wherein the first section 241 is extended along the axial direction of the installation cavity 22, the second section 242 is extended circumferentially along the cavity wall of the installation cavity 22, and the third section 243 is extended along the axial direction of the installation cavity, and the axis of the first section 241 and the axis of the third section 243 are aligned so that the first section 241 and the third section 243 of the ventilation channel 24 are not on the same straight line, thereby ensuring that each ventilation channel 24 can extend in a zigzag manner on the cavity wall of the installation cavity 22.

[0106] In one specific embodiment, the first section 241 of the ventilation channel 24 is formed on the wall of the mounting chamber 22 abutting the first liquid guide member 31, and extends in a straight line along the axial direction of the mounting chamber 22 to connect to the corresponding ventilation outlet 2411. The second section 242 of the ventilation channel 24 is formed on the upper end surface of the fixing platform 221 facing the air guide tube 12, and extends in an arc shape along the circumferential direction of the wall of the mounting chamber 22. The third section 243 of the ventilation channel 24 is formed on the curved inner wall of the fixing platform 221, and extends in a straight line along the axial direction of the mounting chamber 22 to connect to the corresponding ventilation inlet 2431. In this way, the path of each ventilation channel 24 on the wall of the mounting chamber 22 is arranged in a zigzag manner that is approximately "Z"-shaped, which can minimize the risk of leakage in the ventilation channel 24 and ensure that the atomizer 10 will not easily leak during transportation, shelf life, and use.

[0107] During actual use, the atomized matrix in the liquid storage chamber 4 flows downward to the liquid inlet channel 41 at its lower part under the action of gravity, and is evenly distributed to the first liquid storage member 31 under the loop guidance of the liquid guide groove 21, playing the role of annular liquid distribution, and cooperates with at least one ventilation channel 24 to control the continuity and consistency of the liquid output of the atomized matrix in the liquid storage chamber 4, achieve oil supply balance, and thus ensure the uniformity of the aerosol generated by atomization, which can significantly improve the quality of the formed atomized gas and enhance the user's smoking experience.

[0108] See also Figure 2 and Figure 8 In some embodiments, the atomizer 10 further includes at least two seals 8 , which are respectively sealed and clamped between the outer wall of the fixing base 2 and the inner wall of the shell 1 , and between the outer wall of the bottom cover 6 and the inner wall of the shell 1 .

[0109] As an example, the number of the sealing members 8 is two, which are respectively recorded as a first sealing member 81 and a second sealing member 82. The first sealing member 81 and the second sealing member 82 are preferably both sealing rings.

[0110] See also Figure 5 and Figure 7 In coordination, a first sealing groove 29 is circumferentially provided on the outer wall of the fixing base 2, and a second sealing groove 65 is circumferentially provided on the inner wall of the bottom cover 6. A first sealing member 81 is sleeved in the first sealing groove 29, and a second sealing member 82 is sleeved in the second sealing groove 65. After the entire assembly is completed, the first sealing member 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 member 82 seals the gap between the outer wall of the bottom cover 6 and the inner wall of the housing 1.

[0111] The atomizer 10 provided in the present application has a first sealing member 81 and a second sealing member 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 the atomizer 10 from leaking after being placed for a long time, and provide a better sealing effect.

[0112] In some embodiments, the bottom cover 6 and the shell 1 are preferably provided with a matching snap-fit ​​fixing structure (not shown). The bottom cover 6 is detachably connected to the bottom of the shell 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.

[0113] See also Figure 1 、 Figure 3 and Figure 7 The snap-fit ​​fixing structure includes at least one set of cooperating snap-fitting portions 66 and snap-fitting slots 17. In one embodiment, the snap-fitting portions 66 are symmetrically arranged on the outer wall of the bottom cover 6, and the snap-fitting slots 17 are symmetrically arranged on the bottom outer wall of the housing 1 near the mounting notch 14, and engage with the snap-fitting portions 66 in a one-to-one manner. When the bottom cover 6 is installed in the mounting notch 14, the snap-fitting portions 66 snap into the corresponding snap-fitting slots 17, thereby securing the bottom cover 6 to the housing 1 and limiting the position of the fixing base 2 and the atomizer assembly 3.

[0114] See also Figure 10 In some embodiments of the present application, an atomization device 100 is provided, which includes a power supply device 20 and an atomizer 10 as described above. The atomizer 10 is detachably connected to the power supply device 20 and is electrically connected to the power supply device 20.

[0115] See also Figure 10 In one embodiment, the power supply device 20 includes a housing 9 having a mounting slot 91 and a power supply module 92. The atomizer 10 is detachably connected to the mounting slot 91 and electrically connected to the power supply module 92, so that the power supply module 92 supplies power to the heating element 34 of the atomizer assembly 3. After the atomizer substrate in the atomizer 10 is exhausted, a new atomizer 10 can be installed in the mounting slot 91 of the power supply device 20, thereby enabling the power supply device 20 to be reused.

[0116] See also Figure 10 In some embodiments, the power supply device 20 further includes two power terminals 93 provided on the housing 9 and electrically connected to the power supply module 92. The power terminals 93 include a positive power terminal 931 and a negative power terminal 932. The power terminals 93 are at least partially located within the mounting slot 91 and at least partially extend to electrically connect to the power supply module 92.

[0117] When the atomizer 10 is mounted on the mounting groove 91, the positive electrode sheet 711 on the bottom cover 6 abuts against the positive electrode terminal 931, and the negative electrode terminal 932 on the bottom cover 6 abuts against the negative electrode terminal 932, so as to electrically connect the power supply module 92 and the heating element 34 through the electrode terminal 93 and the conductive element 7, and supply power to the heating element 34.

[0118] The air inlet channel 94 is also arranged on the power supply device 20, one end of which extends to the bottom surface of the mounting groove 91 and forms an air outlet 941, and the other end of which extends to the bottom of the casing 9 and forms an air inlet 942.

[0119] In actual use, the air outside the atomization device 100 enters the air inlet channel 94 through the air inlet 942, then enters the mounting groove 91 through the air outlet 941, and then enters the atomizer 10 through the air inlet 61, so as to use the airflow to take away the aerosol generated by heating in the atomization airway 331 of the second liquid guide 33 and mix to form atomized gas, and the atomized gas is finally sent to the air outlet 15 through the air guide pipe 12 for the user to inhale.

[0120] The above application of specific examples to the technical solutions of the present application are described, which is only used to help understand the content of the present application, and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
