At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0046] See also Figure 1 to Figure 2 , Figures 8 to 9 In some embodiments of the present application, an atomizer 10 is provided. The atomizer 10 comprises a housing 1, a fixing seat 2, and an atomizing assembly 3. The fixing seat 2 is fixed in the housing 1. The fixing seat 2 is preferably sealed and embedded in the housing 1 by means of interference fit, and the fixing seat 2 is provided with an installation cavity 22 (such as a mounting cavity 22 connected to the liquid storage cavity 4) in the axial direction. Fig. 9 ).

[0047] See also Figure 2 and Fig. 9 The atomizing assembly 3 is accommodated in the mounting cavity 22, and is used to heat the atomizing matrix and generate aerosol. The atomizing assembly 3 includes a liquid guiding assembly (not shown) and a heating element 34. The liquid guiding assembly includes a first liquid guiding element 31 and a second liquid guiding element 33, wherein the second liquid guiding element 33 is isolated from the liquid storage cavity 4, and the second liquid guiding element 33 forms an atomizing airway 331 on the side facing away from the first liquid guiding element 31, and the atomizing airway 331 preferably runs through both ends of the second liquid guiding element 33 in the axial direction. The heating element is accommodated in the atomizing airway 331, and at least partially adheres to the inner wall surface of the second liquid guiding element 33, and is used to atomize the atomizing matrix transferred by the second liquid guiding element. The first liquid guiding member 31 is sleeved on the periphery of the second liquid guiding member 33 and is fluidically connected to each other, and at least a portion of the first liquid guiding member 31 is connected to the liquid storage chamber 4, for absorbing the atomized matrix in the liquid storage chamber 4 and transmitting it to the second liquid guiding member 33, so that the atomized matrix can be heated by the heating member 34 at the atomizing airway 331 of the second liquid guiding member 33 to generate aerosol and realize atomization and smoking for the user to inhale.

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

[0049] In the atomizer 10 provided in the present application, the liquid guide component of the atomization component 3 uses the first liquid guide member 31 to absorb the atomized matrix and transmit it to the second liquid guide member 33, which plays the role of absorbing liquid, storing liquid, and guiding liquid, 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, ensuring the continuous and stable supply of the atomized matrix during the suction use process, and also effectively avoiding the problem of leakage of the atomized matrix due to long-term placement on the shelf and vibration during transportation, thereby improving the user experience.

[0050] See also Figure 4 and Fig. 9 In some embodiments, a liquid guiding groove 21 is further provided on the side of the fixing seat 2 facing the liquid storage chamber 4. A first liquid guiding member 31 is fixed in the fixing seat 2, and the first liquid guiding member 31 extends into the liquid guiding groove 21 toward the upper end of the liquid storage chamber 4. The housing 1 and the groove wall of the liquid guiding groove 21 jointly define a liquid inlet channel 41, and the liquid guiding component 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 gravity direction, and can drain the atomized matrix in the liquid storage chamber 4 to the first liquid guide member 31 of the liquid guide component, thereby playing the role of drainage and flow limiting, 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 amount of the first liquid guide member 31, so that the first liquid guide member 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 member 33 for the atomized matrix being greater than the consumption rate of the atomized matrix during use, thereby causing leakage problems, and significantly reducing the risk of leakage.

[0052] See also Figure 4 and Fig. 9 In a specific embodiment, the liquid guide groove 21 is arranged at the upper end of the fixing seat 2 facing the liquid storage cavity 4, and is axially concave inside the fixing seat 2 to communicate with the mounting cavity 22, and the inner diameter of the liquid guide groove 21 is larger than the inner diameter of the mounting cavity 22, so that the liquid guide groove 21 surrounds one end of the mounting cavity 22 facing the liquid storage cavity 4. The first liquid guide member 31 is preferably arranged 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 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 uniformly guiding the atomized matrix to the first liquid guide member 31, and 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, a plurality of liquid guide grooves 21 may be provided, formed by a radial inward concave portion of the cavity wall at one end of the installation cavity 22 opening toward the liquid storage cavity 4, and the plurality of liquid guide grooves 21 are preferably centrally symmetrically distributed with the axis of the installation cavity 22 as the center, so that the plurality of 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 circumferentially distributed at the upper end of the first liquid guide member 31 are defined between the shell 1 and the groove walls of the plurality of liquid guide grooves 21, and the atomized matrix can be guided from different positions to the first liquid guide member 31 through the distributed plurality of liquid inlet channels 41, and the amount of liquid absorbed and the liquid distribution effect of the liquid guide component per unit time can be controlled by adjusting the number of liquid guide grooves 21, the groove capacity, the setting position, etc., 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 1% to 40% of the overall length of the first liquid guide member 31. On the one hand, it can ensure that the lower part of the first liquid guide member 31 has sufficient length to be inserted into the installation cavity 22 and has an interference fit with the installation cavity 22, thereby ensuring the stability and reliability of the atomization assembly 3 being accommodated in the installation cavity 22. On the other hand, it can also ensure 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, so that the first liquid guide member 31 can achieve consistency in the transmission of the atomization matrix to achieve a balanced liquid supply, preventing the first liquid guide member 31 from being oversaturated and leaking, further improving the sealing of the atomizer 10 of the present application, and reducing the risk of leakage.

[0056] See also Fig. 9In some embodiments, a guide surface 211 is provided on the side of the liquid guide groove 21 facing the liquid storage chamber 4. The guide surface 211 extends obliquely from one end of the fixing seat 2 close to the liquid storage chamber 4 to the lower end of the fixing seat 2 facing away from the liquid storage chamber 4, and gradually converges to the end of the first liquid guide member 31 extending into the liquid guide groove 21, so that the vertical cross-section of the liquid guide groove 21 is wedge-shaped. The guide surface 211 can be a plane or a curved surface, which is not limited in the present application, and the atomized substrate can be guided to the first liquid guide member 31 through the guide surface 211.

[0057] See also Fig. 9 In a specific embodiment, the bottom groove 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 to form a funnel-like annular guide surface 211, so that the atomized matrix in the liquid inlet channel 41 at the bottom of the liquid storage chamber 4 can be guided by the guide surface 211 and flow evenly to 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 atomization component 3 on the atomized matrix. In addition, the retractable structural design of the groove wall at the bottom of the liquid guide groove 21 is also conducive to the assembly of the atomization component 3 in the axial direction and plugged into the installation cavity 22 through the liquid guide groove 21, 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, plays the role of absorbing, storing and guiding liquid, and combined with the structural design of the annular guide surface 211 of the liquid guide groove 21, the atomized matrix can be uniformly transmitted to the first liquid guide member 31 in all directions. The first liquid guide member 31 and the second liquid guide member 33 are connected to each other by the capillary phenomenon between the micropores of the material itself, and the atomized matrix is ​​transmitted, so that the atomized matrix on the first liquid guide member 31 can be uniformly transmitted to the second liquid guide member 33, and then heated by the heating element 34 accommodated in the atomizing airway 331, ensuring that the atomized matrix can be uniformly heated to atomization, ensuring the consistency of taste during inhalation, and avoiding the problem of sticking the core caused by 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, thereby ensuring the balance between supply and demand of the atomization matrix, and at the same time, the liquid locking effect is better, 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, and can quickly transfer the atomized matrix 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 to 3 The housing 1 is commonly known as an oil cup in the art. In some embodiments, the housing 1 is preferably made of PP plastic material and has a receiving cavity 11 inside. The housing 1 is vertically arranged along the gravity direction. The upper end of the housing 1 is provided with a suction nozzle 13, the lower end is provided with a mounting notch 14, and the suction nozzle 13 is formed with an air outlet 15 on the housing 1 (such as Figure 2 As shown in FIG. 1 , 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 to 9 The housing 1 is also provided with an air guide tube 12 which is connected to the outside through the air outlet 15, and 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 seat 2 and abuts against the first liquid guide member 31. The outlet end of the atomizing airway 331 is connected to the air guide tube 12 and is connected to the outside through the air outlet 15. The outer wall surface of the air guide tube 12, the upper end of the fixed seat 2, the first liquid guide member 31 extending into the liquid guide groove 21, and the inner wall surface of the housing 1 jointly define the liquid storage chamber 4.

[0062] Please refer to 4. Figures 8 to 9 In coordination therewith, a fixing platform 221 is provided on the cavity wall of the installation cavity away from the air guide tube 12, and both 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 seat 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 installation cavity 22 of the fixing seat 2 first, so that the atomizer assembly 3 as a whole is assembled with the fixing seat 2 to form a vertical combination, and then the formed vertical combination is axially inserted into the shell 1 through the installation 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 seat 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 seat 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 achieve further restriction on the axial length of the first liquid guide member 31, which can prevent 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 too much atomized matrix, and further reducing the risk of leakage of the atomizer 10.

[0065] In addition, the fixing seat 2 and the shell 1 in the atomizer 10 of the present application are fixedly assembled by interference fit, which can achieve a good seal between the outer wall of the fixing seat 2 and the inner wall of the shell 1, ensuring that the atomizer 10 is not prone to leakage during transportation, shelf life, and use, and can eliminate the need for a silicone sealing ring, thereby avoiding the problem of aroma attenuation caused by the atomization matrix in the liquid storage chamber 4 directly contacting the silicone material.

[0066] See also Figure 3 , Figure 8 In some embodiments, the cross-sectional shape of the accommodating cavity 11 of the housing 1 in the horizontal plane is preferably set to be circular, and the air duct 12 extends axially from the air outlet 15 to one side of the installation slot 14 along the axis of the accommodating cavity 11.

[0067] See also Figure 4 , Fig. 9 , the fixing seat 2 is configured as a cylindrical structure that matches the inner wall of the accommodating cavity 11 of the housing 1, and the mounting cavity 22 is preferably configured to extend along the axial centerline A of the atomizer 10 and be coaxial with the accommodating cavity 11. In this way, the housing 1, the fixing seat 2, the atomizing assembly 3 and other components of the atomizer 10 of the present application can be automatically assembled in an axially stacked manner. Compared with the existing design, it has the advantages of simple structure, fewer parts and convenient installation, and can significantly reduce the production cost of the atomizer 10.

The air vent 251 is preferably arranged at the bottom center of the installation cavity 22 to connect the external space of the fixing seat 2 with the installation cavity 22, and the air vent 251 is connected to the atomizing airway 331 in the second liquid guiding member 33, so that the external air of the atomizer 10 can enter the atomizing airway 331 through the air vent 251 and mix with the aerosol generated by atomization to form atomized gas.

[0069] See also Figure 4 and Fig. 9 In some embodiments, the fixing platform 221 is preferably arranged around the lower cavity wall of the installation cavity 22 and connected to the bottom surface of the installation cavity 22, so that the inner side of the fixing platform 221 forms an annular inner wall, and the vent hole 251 is arranged at the center of the inner wall of the fixing platform 221.

[0070] In some other embodiments, the fixing platform 221 can also be set as multiple, circumferentially distributed on the lower cavity wall of the installation cavity 22, and the inner sides of the multiple fixing platforms 221 together constitute a discontinuous annular inner wall structure, and the vent hole 251 is set at the center of the inner wall of the fixing platform 221.

[0071] See also Figure 2 and Fig. 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 plugged into the air guide tube 12 and connected to the air outlet 15, and the lower end of the atomizing tube 32 facing away from the liquid storage chamber 4 is plugged into the installation chamber 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.

[0072] See also Figure 6 , Figure 8 and Fig. 9 After the atomization component 3 is assembled, the second liquid guide member 33 is received in the atomization tube 32, and the liquid inlet 321 is at least partially closed from the inside; the first liquid guide member 31 is sleeved on the outside of the atomization tube 32, and the liquid inlet 321 is at least partially closed from the outside. The heating element 34 is received in the second liquid guide member 33 and electrically connected to an external power source. In actual use, the atomized matrix adsorbed on the first liquid guide member 31 is transmitted to the second liquid guide member 33 via the liquid inlet 321, so as to realize the fluid connection between the first liquid guide member 31 and the second liquid guide member 33. The heating element 34 generates heat under the drive of electricity, thereby heating the atomized matrix transmitted to the inner wall surface of the second liquid guide member 33 and within the operating range of the heating element 34 until it is atomized and generates an aerosol.

[0073] In a specific embodiment, the outer diameter of the atomizer tube 32 preferably matches the inner diameter of the annular inner wall of the fixed platform 221, so that the lower end of the atomizer tube 32 can be fixedly inserted into the fixed platform 221 in an interference fit manner, and the lower outer wall surface of the atomizer tube 32 is at least partially sealed against the annular inner wall of the fixed platform 221 to form a good seal. In coordination, the inner wall of the air guide tube 12 facing the lower end of the fixed seat 2 is provided with a plug-in groove (not marked) whose inner diameter matches the outer diameter of the atomizer tube 32. During assembly, the lower end of the atomizer tube 32 is plugged and fixed on the annular inner wall of the fixed platform 221, and the upper end of the atomizer tube 32 is plugged and fixed on 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 atomizer tube 32, the cavity wall of the installation 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 guide member 31, ensuring that the atomizer 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 , so that 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 sucks the nozzle 13 at the upper end of the shell 1 with his mouth to generate negative pressure inside the shell 1, and the outside air enters the atomizing tube 32 through the vent hole 251 and flows to the atomizing airway 331 in the second liquid guide 33. At the same time, the atomizing matrix in the liquid storage chamber 4 flows to the first liquid guide 31 along the guide surface 211 of the liquid guide groove 21 under the guidance of the liquid inlet channel 41, and is then adsorbed by the first liquid guide 31 and transmitted to the second liquid guide 33 through the liquid inlet 321, and then transmitted to the inner wall surface of the second liquid guide 33, and then heated by the heating element 34 to atomize and generate aerosol. The generated aerosol is mixed with the airflow in the atomizing airway 331 to form atomized gas, and the atomized gas is finally discharged through the gas outlet 15 under the transmission of the air guide tube 12 for the user to inhale.

[0077] See also Figure 4 and Fig. 9 In some embodiments, the fixing seat 2 is further provided with a vent 25, which is a hollow tubular structure, extending axially from the bottom surface of the mounting cavity 22 to the annular inner wall of the fixing platform 221, and the bottom of the vent 25 penetrates the bottom end of the fixing seat 2 facing away from the air guide tube 12, and forms the vent hole 251. On the one hand, the vent 25 can introduce the air entering through the vent 251 into the atomizing tube 32 and send it to the atomizing airway 331, and 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 atomizing matrix can be accumulated through the bottom annular groove 23, which can prevent the atomizing matrix leaking into the mounting cavity 22 from leaking directly through the vent 251.

[0078] In addition, the air entering the atomizer tube 32 through the ventilation portion 25 can flow downward to the bottom ring groove 23 and accumulate, which reduces the risk of oil explosion during use, increases the airflow supply in the atomizer tube 32, increases the concentration of each puff of atomized gas, and improves the user's smoking experience.

[0079] See also Figures 1 to 3 , Figure 8 In some embodiments, the atomizer 10 further includes a bottom cover 6, which is preferably snap-fitted and fixed to a 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 to 9 After the bottom cover 6 is snap-fitted and fixed in the installation slot 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 Fig. 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 seat 2 can be assembled to form a vertical assembly first, and then the formed vertical assembly can be axially inserted into the shell 1 through the installation slot 14, and finally the bottom cover 6 can be axially installed on the installation slot 14 at the bottom of the shell 1, and the fixing seat 2 can be pressed against the bottom cover 6 to limit and fix the fixing seat 2 and the atomizer assembly 3 in the shell 1.

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

[0084] During actual use, the user draws on the suction 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, and the air in the air inlet cavity 5 then flows into the atomization tube 32 through the vent hole 251.

[0085] See also Fig. 9 In some embodiments, the axes of at least two air inlets 621 are offset from the axes of the vent holes 251, which can prevent the air in the outside atmosphere from flowing directly into the vent holes 251 through the air inlets 621, and make part of the air flow in a circuitous manner in the air inlet cavity 5, which can further reduce the problem of oil frying and uneven atomized particles caused by direct air flow during use. In addition, the staggered arrangement can also prevent the vent 25 from causing leakage by causing air condensate or atomized matrix leaking from the installation cavity 22 to drip directly into the air inlet 621 through the vent holes 251.

[0086] See also Figures 7 to 9 In some embodiments, the bottom cover 6 is further provided with an air inlet 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 62 penetrates the bottom end of the bottom cover 6 facing away from the air guide tube 12 and forms an air inlet 61 (such as Fig.10 The upper end of the air inlet portion 62 facing the fixing seat 2 is at least partially a closed structure, and a plurality of branch pipe portions (not shown) are axially extended. The branch pipe portions are arranged in a centrally symmetrical manner with the axis of the air inlet portion 62 as the center, and the upper end of each branch pipe portion is axially penetrated by an air inlet hole 621.

[0087] When in use, air in the outside atmosphere first enters the air inlet portion 62 through the air inlet port 61, flows to the air inlet holes 621 through the branch pipes, and merges into the air inlet cavity 5, and then enters the bottom annular groove 23 through the vent hole 251 and the vent portion 25. Since the axis of each air inlet hole 621 is misaligned with the axis of the vent hole 251, the airflow discharged from the air inlet hole 621 will form a circuitous airflow in the air inlet cavity 5 due to the obstruction of the bottom end surface of the fixing seat 2, further reducing the risk of oil explosion during the 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, the air inlet 61 and the air outlet 15 can be prevented from entering the air inlet 61 and the air outlet 15. On the other hand, the atomizer 10 can be sealed 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 the 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 guiding member 33, and the heating mesh 341 with a cylindrical structure is attached to the inner wall surface of the second liquid guiding member 33.

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

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

[0092] See also Figures 6 to 8In a 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, and the positive pin 3421 and the negative pin 3422 do not contact each other.

[0093] 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 pin 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 sheet 711; the upper end of the negative conductive component 72 abuts against the negative pin 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 sheet 721.

[0094] See also Figures 4 to 5 , the bottom of the fixing seat 2 is also provided with two pin through holes 27 for the positive pin 3421 and the negative pin 3422 to extend out of the installation cavity 22, and the two pin through holes 27 both penetrate the bottom ring groove 23. The bottom end surface of the fixing seat 2 facing away from the air guide tube 12 is also provided with two concave pin positioning grooves 28 respectively connected to the corresponding pin through holes 27. After assembly, the positive pin 3421 and the negative 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 bending. The upper end of the positive conductive member 71 is at least partially inserted into the corresponding pin positioning groove 28 and abuts the positive pin 3421, and the upper end of the negative conductive member 72 is at least partially inserted into the corresponding pin positioning groove 28 and abuts the negative pin 3422, so as to establish an electrical connection relationship between the conductive member 7 and the heating element 34.

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

[0096] See also Figure 5, in coordination, the bottom end of the fixing seat 2 facing away from the air guide tube 12 is provided with two concave 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 combination of the fixing seat 2 and the atomizing assembly 3 can be limited and fixed inside the housing 1 through the positioning support parts 63 to ensure the assembly of the various components inside the atomizer 10. On the other hand, the positioning support parts 63 can cooperate with the positioning grooves 26 to limit the installation position and installation angle of the fixing seat 2 and the bottom cover 6, ensuring that the bottom cover 6, the fixing seat 2 and the atomizing 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 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 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 being unable 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 seat 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 seat 2. When negative pressure appears 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 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 penetrating the liquid guide groove 21 and forms a ventilation outlet 2411, which is connected 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 is connected to the air inlet 5. When the liquid storage chamber 4 generates negative pressure during use, the air in the air inlet 5 can be merged into the bottom annular groove 23 through the ventilation inlet 2431, and under the guidance of the ventilation channel 24, it can be replenished into the liquid storage chamber 4 through the ventilation outlet 2411 to balance the air pressure inside and outside the liquid storage chamber 4, ensuring that the liquid storage chamber 4 can continuously and smoothly supply the atomized matrix.

[0101] See also Figure 4 In a specific embodiment, the number of ventilation channels 24 is two, 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.

[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 beneficial to the uniform discharge of liquid from the liquid storage chamber 4.

[0103] See also Figure 4 In some embodiments, each ventilation channel 24 is configured to be formed by the concave cavity wall of the installation cavity 22, so that the outer wall surface of the first liquid guide 31 can form a sealing effect on the notch of the ventilation channel 24 on the outside, and the liquid absorption effect of the first liquid guide 31 can be used to absorb the atomized matrix accidentally leaked into the ventilation channel 24, which can reduce the risk of the atomized matrix in the liquid storage cavity 4 leaking through the ventilation channel 24. In addition, the ventilation channel 24 is formed by the concave cavity wall of the installation cavity 22, which is conducive to the integral molding of the fixing seat 2, and can reduce the structural complexity and production cost of the fixing seat 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, 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, 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, ensuring that each ventilation channel 24 can extend in a zigzag manner on the cavity wall of the installation cavity 22.

[0106] In a 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 member 31, and extends along the axial straight line 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 surface of the fixing platform 221 facing the air guide tube 12, and extends in an arc along the circumferential direction of the cavity wall of the mounting cavity 22; the third section 243 of the ventilation passage 24 is formed on the arc-shaped inner wall of the fixing platform 221, and extends along the axial straight line 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 zigzag extension similar to a "Z" shape, 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.

[0107] During actual use, the atomized matrix in the liquid storage chamber 4 flows downward to the liquid inlet channel 41 at the lower part thereof under the action of gravity, and is evenly distributed to the first liquid storage member 31 under the guidance of the loop of the liquid guide groove 21, playing the role of annular liquid distribution, and cooperating 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, to achieve oil supply balance, and thus to 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] The number of the sealing members 8 is two, for example, 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 arranged on the outer wall of the fixing seat 2, a second sealing groove 65 is circumferentially arranged 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 overall assembly, the first sealing member 81 seals the gap between the outer wall of the fixing seat 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 seal 81 and a second seal 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), and 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 the disassembly and assembly of the atomizer 10 is convenient.

[0113] See also Figure 1 , Figure 3 and Figure 7 The snap-fit ​​fixing structure includes at least one set of snap-fitting snap-fitting parts 66 and snap-fitting grooves 17. In a specific embodiment, the snap-fitting parts 66 are symmetrically arranged on the outer wall of the bottom cover 6, and the snap-fitting grooves 17 are symmetrically arranged on the bottom outer wall of the housing 1 near the mounting notch 14, and are snap-fitted with the snap-fitting parts 66 one-to-one. When the bottom cover 6 is installed in the mounting notch 14, the snap-fitting parts 66 are snap-fitted and fixed in the corresponding snap-fitting grooves 17, so as to fix the bottom cover 6 on the housing 1 and limit the fixing seat 2 and the atomizer assembly 3.

[0114] See also Fig.10 In some embodiments of the present application, an atomization device 100 is provided, and the atomization device 100 includes a power supply device 20 and an atomizer 10 as described in any one of the 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 Fig.10 In a specific embodiment, the power supply device 20 includes a housing 9, which is provided with 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 as to supply power to the heating element 34 of the atomization assembly 3 through the power supply module 92. After the atomization 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, so that the power supply device 20 can be reused.

[0116] See also Fig.10 In some embodiments, the power supply device 20 further includes two power terminals 93 disposed 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, and the power terminals 93 are at least partially located in the mounting groove 91 and at least partially extended to be electrically connected to the power supply module 92.

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

[0118] The power supply device 20 is also provided with an air inlet passage 94 , one end of which extends to penetrate the bottom surface of the mounting slot 91 and forms an air outlet 941 , and the other end of which extends to penetrate the bottom of the housing 9 and forms an air inlet 942 .

[0119] During actual use, the air outside the atomizing device 100 enters the air inlet 94 through the air flow inlet 942, then enters the mounting groove 91 through the air flow outlet 941, and then enters the atomizer 10 through the air inlet 61, thereby utilizing the air flow to carry away the aerosol generated by heating in the atomizing airway 331 of the second liquid guiding member 33 and mix to form atomized gas, and the formed atomized gas is finally sent to the air outlet 15 through the air guide tube 12 for discharge for the user to inhale.

[0120] The above specific examples are used to illustrate the technical solution of this application, which is only used to help understand the content of this application and is not intended to limit this application. For technicians in the technical field to which this application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of this application.
