Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] The electronic atomization device uses the heating element in the atomization core to heat the atomization matrix on the atomization surface transmitted by the liquid guide to generate atomized gas. For cartridge-changing electronic atomization devices, how to ensure that the product does not leak for a long period of time from the time it leaves the factory to the time it is smoked by the consumer has always been a more difficult problem in this field. The commonly used method at present is to design the cartridge-type atomizer as an oil-core separation structure, isolating the atomization core and the atomization matrix in the liquid storage chamber before use, so as to ensure that the atomization matrix of the cartridge-changing electronic atomization device product can be completely isolated from the atomization core during the period from the factory end to the unpacking and use of the customer end. On the one hand, it can avoid leakage before the product is used, and on the other hand, it can also avoid the adverse effects of the atomization core being immersed in the atomization matrix for a long time.

[0003] The atomizer structure of existing cartridge-replaceable electronic atomizer devices is generally complex and has many components in order to achieve the oil core separation state before use and the oil core conduction state during use. Most of them require manual assembly, which is not conducive to automated production, inconvenient production and assembly, high cost, and poor economic efficiency. Utility Model Content

[0038] The technical solution of the present application will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by their components, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the field.

[0039] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated that a certain sequence must be followed.

[0040] Please refer to Figures 1 to 7 , in some embodiments of the present application, an atomizer 10 is provided, which includes a housing 1, an atomization core 2, a closure 3, and a bottom cover 4. The housing 1, which is commonly known as the oil cup, is generally a vertically - shaped cylindrical structure with an internal cavity, and an installation notch 11 (as shown in Figure 7 ) communicating with its cavity is opened at the bottom, and a mouthpiece 12 is provided at the top. An air outlet hole 121 communicating with the inner cavity of the housing 1 for discharging the atomized gas is opened at the end of the mouthpiece 12.

[0041] Inside the housing 1, there is an atomizing air duct 13 that communicates with the outside through an air outlet hole 121. The atomizing air duct 13 preferably extends axially from the air outlet hole 121 towards one end of the installation slot 11, and its length can extend to the middle of the cavity of the housing 1, so as to leave enough space between the outer wall surface of the atomizing air duct 13 and the inner wall surface of the housing 1 for storing the atomizing matrix.

[0042] The atomizing core 2 is a component in the atomizer 10 that adsorbs and transports the atomizing matrix, and heats and generates aerosol from the atomizing matrix under the drive of electricity. It is assembled as a whole in the housing 1 in the form of a component. After assembly, the upper end of the atomizing core 2 is connected to the bottom end of the atomizing air duct 13, and the outer peripheral side of the atomizing core 2 abuts against the inner wall surface of the housing 1, so as to define a liquid storage cavity 14 for storing the atomizing matrix between the inner wall surface of the atomizing core 2 and the housing 1 and the outer wall surface of the atomizing air duct 13. The atomizing matrix is illustrated by liquid e-liquid as an example. An atomizing channel 231 communicating with the atomizing air duct 13 axially penetrates through the atomizing core 2, and a liquid inlet 20 communicating with the liquid storage cavity 14 is provided on the atomizing core 2. When the atomizing core 2 works under the drive of electricity, the e-liquid entering through the liquid inlet 20 is heated and generates aerosol. The aerosol mixes with air in the atomizing channel 231 to form atomized gas and enters the atomizing air duct 13, and finally is discharged through the air outlet hole 121 on the mouthpiece 12 for the user to inhale.

[0043] The closure 3 is movably connected to the atomizing core 2 and can axially move relative to the atomizing core 2, so that the closure 3 can close or expose the liquid inlet 20.

[0044] The bottom cover 4 is a component for closing the installation slot 11 and limiting the atomizing core 2 in the housing 1. An air inlet hole 411 is provided at the bottom of the bottom cover 4, and outside air enters the housing 1 through the air inlet hole 411 and flows into the atomizing channel 231. A driving member 44 for movably connecting the closure 3 and driving the closure 3 to axially move along the atomizing core 2 is provided on the bottom cover 4.

[0045] Please refer to Figure 4 , when the bottom cover 4 is pre-assembled at the bottom of the housing 1 in the first installation position, the closure 3 closes the liquid inlet 20; please refer to Figure 5 , when the bottom cover 4 axially moves to the second installation position and is assembled with the housing 1, the driving member 44 drives the closure 3 to axially move to expose the liquid inlet 20.

[0046] The atomizer 10 provided by the present application includes a housing 1, an atomization core 2, a closure 3, and a bottom cover 4. An atomization air duct 13 is provided inside the housing 1. The atomization core 2 is disposed in the housing 1, and its upper end is connected to the atomization air duct 13, and a liquid storage cavity 14 is defined between the housing 1 and the atomization air duct 13. An atomization channel 231 communicating with the atomization air duct 13 is provided inside the atomization core 2, and a liquid inlet 20 communicating with the liquid storage cavity 14 is provided on the atomization core 2. The closure 3 is movably connected to the atomization core 2 and moves axially. A driving member 44 is provided on the bottom cover 4 for movably connecting and driving the closure 3 to move. When the bottom cover 4 is pre-assembled at the bottom of the housing 1 in the first installation position, the closure 3 closes the liquid inlet 20. When the bottom cover 4 axially moves to the second installation position and is assembled with the housing 1, the driving member 44 drives the closure 3 to axially move to expose the liquid inlet 20.

[0047] Please refer to Figures 1 to 4 , when the atomizer leaves the factory, the bottom cover 4 is assembled in the first installation position. At this time, the driving member 44 cannot drive the closure 3 to move, and the closure 3 closes the liquid inlet 20 on the atomization core 2, isolating the atomization matrix in the liquid storage cavity 14 from the atomization core 2, realizing oil-core separation, ensuring that during the period from the factory end to the client's unpacking and use, the atomization matrix can be completely isolated from the atomization core 2. On the one hand, it can avoid liquid leakage before product use, and on the other hand, it can also avoid the adverse effects on the atomization core 2 caused by long-term immersion in the atomization matrix.

[0048] Please refer to Figures 5 to 7 , after the consumer purchases the product, only by manually pressing the bottom cover 4 to move it from the first installation position to the second installation position, the driving member 44 can be synchronously driven to move, and the driving member 44 can drive the closure 3 to axially move to expose the liquid inlet 20, so as to introduce the atomization matrix in the liquid storage cavity 14 into the atomization core 2 through the liquid inlet 20, realizing oil-core conduction, activating and normally using the atomizer. In the atomizer 10 provided by the present application, the driving member 44 is integrated on the bottom cover 4, so that the two can move synchronously. Furthermore, when the bottom cover 4 moves from the first installation position to the second installation position, the atomizer is activated, significantly reducing the complexity of the internal structure of the atomizer, reducing the number of components, facilitating the automated production and assembly of the product, significantly improving production efficiency, reducing production costs, and having higher economic efficiency. In addition, after the consumer purchases the product, only by manually pressing the bottom cover 4 can the activation be realized, with simple and convenient operation, facilitating use, and improving the user experience.

[0049] Please refer to Figures 1 to 2 , in some embodiments, the atomization core 2 includes a base body 21, a core tube 22, a liquid guiding member 23, and a heating member 24. An atomization cavity 210 is axially penetrated through the base body 21 (such as Figure 4 , Figure 5 , Figure 8As shown in [figure reference]. The core tube 22 is a tubular structure with openings at both ends and is entirely housed within the atomization chamber 210 of the base body 21, enabling the inner cavity of the core tube 22 to communicate with the atomization chamber 210. The core tube 22 is preferably made of ceramic material, or it can also be made of other materials that meet the requirements, ensuring it has sufficient strength to serve as a framework for supporting and fixing the liquid guiding member 23 and the heating member 24, as well as for heat insulation and protection. The outer diameter of the core tube 22 matches the inner diameter of the atomization chamber 210 so that they can be inserted and fixed by interference fit to prevent the core tube 22 from axially moving in the atomization chamber 210.

[0050] The liquid guiding member 23 is a component in the atomization core 2 for adsorbing and transporting the atomization matrix. It can be made of ceramic material, fiber cotton material, or it can also be set as a combination and assembly of multiple sub-liquid guiding members made of the same or different materials. This application does not limit this. The liquid guiding member 23 is entirely housed within the inner cavity of the core tube 22. The atomization channel 231 axially penetrates the liquid guiding member 23 and forms an atomization surface (not marked) on the inner wall surface of the liquid guiding member 23. The atomization matrix in the liquid storage cavity 14 is finally adsorbed by the liquid guiding member 23 and then transported to the atomization surface for heating and atomization. Since the liquid guiding member 23 is entirely housed within the inner cavity of the core tube 22, and the core tube 22 is entirely housed within the atomization chamber 210 of the base body 21, therefore, the atomization channel 231 of the atomization core 2 can communicate with the atomization air duct 13 through the atomization chamber 210 of the base body 21. The outer diameter of the liquid guiding member 23 preferably matches the inner diameter of the core tube 22 so that they can be inserted and fixed by interference fit to prevent the liquid guiding member 23 from axially moving in the core tube 22.

[0051] Please refer to Figure 9 , the heating member 24 is a component in the atomization core 2 that generates heat under the drive of electricity. Preferably, it includes a heating mesh 241 and electrode pins 242 electrically connected to the heating mesh 241. In this embodiment, the heating member 24 is described by taking one heating mesh 241 and two electrode pins 242 as an example. In some other embodiments, the heating member 24 can also be provided with multiple heating meshes and more than two electrode pins at the same time. The heating mesh 241 of the heating member 24 is preferably wound into a cylindrical shape and entirely housed within the atomization channel 231 of the liquid guiding member 23 and closely attached to the atomization surface to ensure that the heating mesh 241 can heat the atomization matrix in contact with it around the atomization surface to atomize and prevent the heating member 24 from axially moving in the liquid guiding member 23. The two electrode pins 242 (one positive and one negative) of the heating member 24 extend outside the core tube 22 to facilitate connection to the power supply and supply power to the heating mesh 241.

[0052] Please refer to Figure 2 , Figure 5 and Figure 6, the liquid inlet 20 includes at least one first liquid inlet 213 provided on the seat body 21 and communicating with the atomization chamber 210, and at least one second liquid inlet 221 provided on the core tube 22 and communicating with the liquid guiding member 23. The second liquid inlet 221 and the first liquid inlet 213 are correspondingly communicated inside and outside. The liquid guiding member 23 at least partially closes the second liquid inlet 221 from the inside to prevent the atomization matrix from directly pouring into the core tube 22 through the second liquid inlet 221 and flowing into the atomization channel 231. The closing member 3 is movably connected to the seat body 21 on the outer side of the atomization chamber 210, and at least part of the closing member 3 can close the first liquid inlet 213 and the second liquid inlet 221 from the outside, so that when the bottom cover 4 is pre-assembled on the housing 1 at the first installation position, the liquid inlets 20 of the atomization core 2 can be closed by the closing member 3 to achieve oil-core separation.

[0053] After the atomizer is activated, the atomization matrix in the liquid storage chamber 14 can enter through the first liquid inlet 213 on the seat body 21, and flow into the liquid guiding member 23 through the second liquid inlet 221 corresponding to and communicating with the first liquid inlet 213, and then be sent to the atomization surface under the transmission of the liquid guiding member 23, and then be heated and atomized by the heating mesh 241 of the heating member 24 to generate aerosol. The generated aerosol is mixed with air in the atomization channel 231 to form atomized gas, and finally discharged through the atomization guide pipe 13 and the air outlet 121 for the user to inhale.

[0054] The atomizer 10 provided in this application is assembled by combining four components: the seat body 21, the core tube 22, the liquid guiding member 23, and the heating member 24. On the premise of ensuring the heating and atomization effect of the atomization core 2 on the e-liquid, the upper and lower combined assembly in the axial direction can be realized, which is convenient for the automated production of the atomization core 2 and the assembly of the atomization core 2 and the housing 1. In addition, the core tube 22, the liquid guiding member 23, and the heating mesh 241 of the heating member 24 of the atomization core 2 can all adopt common general components on the market, which can improve the compatibility of the atomizer product with the internal components, which is not only conducive to automated assembly, but also can further reduce the product manufacturing cost and improve the enterprise efficiency.

[0055] Please refer to Figures 2 to 7 , and Figure 9 , in some embodiments, the seat body 21 includes a seat tube portion 211 and a sealing portion 212. The seat tube portion 211 is preferably a cylindrical structure with openings at both ends and extends axially as a whole. The atomization chamber 210 axially penetrates the seat tube portion 211. The first liquid inlet 213 is radially provided on the side wall of the seat tube portion 211. The core tube 22, the liquid guiding member 23, and the heating mesh 241 of the heating member 24 are all received in the seat tube portion 211. When the atomization core 2 is assembled in the housing 1 as a whole, the upper ends of the seat tube portion 211 and the core tube 22 are both sealingly sleeved on the lower end of the atomization guide pipe 13.

[0056] The sealing part 212 is provided on the outer side of the lower part of the seat tube part 211 and is connected to the inner wall of the housing 1. When the atomization core 2 is integrally assembled in the housing 1, the top end face of the sealing part 212 and the outer wall face of the seat tube part 211, together with the inner wall face of the housing 1 and the outer wall face of the atomization air guide tube 13, define the liquid storage cavity 14. One end of the atomization channel 231 in the atomization core 2 for admitting air communicates downward through the atomization cavity 210 to the air inlet hole 411 of the bottom cover 4, and the other end of the atomization channel 231 for discharging air communicates upward through the atomization channel 231 to the atomization air guide tube 13.

[0057] The closing member 3 includes a sleeve 31 which is movably sleeved outside the seat tube part 211 and can axially move relative to the seat tube part 211 under the drive of the driving member 44 to expose the first liquid inlet 213. The sleeve 31 is a tubular structure with openings at both ends and is preferably made of food-grade stainless steel material to ensure that it will not be corroded by the e-liquid. The inner diameter of the sleeve 31 matches the outer diameter of the seat tube part 211, so that the two can be inserted in an interference fit manner to prevent the sleeve 31 from easily axially moving outside the seat tube part 211 due to transportation vibration or dropping and bumping before the user uses it, thus avoiding the conduction or leakage of the e-liquid through the wick.

[0058] Please refer to Figure 2 、 Figure 6 and Figure 9 In some embodiments, preferably, there are two first liquid inlets 213 which are radially penetratingly provided on the side wall of the seat tube part 211, and the two first liquid inlets 213 are symmetrically arranged with the axis of the seat tube part 211 as the center. Correspondingly, there are also two second liquid inlets 221 which are radially penetratingly provided on the side wall of the core tube 22 and are respectively in internal and external corresponding communication with the two first liquid inlets 213.

[0059] Please refer to Figure 2 、 Figure 3 and Figure 8 In some embodiments, at least two sealing ring parts 214 are circumferentially arranged around the outer wall of the seat tube part 211 and the inner wall of the sleeve 31 at axially spaced intervals. The sealing ring parts 214 protrude from the outer peripheral surface of the seat tube part 211 and are respectively located outside the two ends of the first liquid inlet 213 in the axial direction. The sealing ring parts 214 are preferably formed on the outer wall surface of the seat tube part 211 and are movably abutted against the inner wall surface of the sleeve 31.

[0060] On the one hand, the sealing ring parts 214 can increase the frictional damping between the sleeve 31 and the seat tube part 211 to prevent the sleeve 31 from easily axially moving. On the other hand, the sealing ring parts 214 can improve the sealing performance between the sleeve 31 and the seat tube part 211 and form an effective seal for the first liquid inlet 213 in the circumferential direction between the two, preventing the e-liquid in the liquid storage cavity 14 from entering the first liquid inlet 213 through the gap between the two, and ensuring the state of wick separation before the product is used.

[0061] See also Figures 2 to 3 、 Figures 6 to 7 In some embodiments, a limiting structure 215 for inserting and limiting the core tube 22 is circumferentially provided on the lower portion of the inner wall of the seat tube portion 211, and the atomization chamber 210 forms a narrowing structure on the bottom of the seat tube portion 211 and the outer wall surface of the limiting structure 215, with the inner diameter gradually decreasing toward one end of the atomization channel 231.

[0062] The present application utilizes a limiting structure 215 on the seat tube portion 211 to limit and secure the core tube 22. This prevents the core tube 22 from being over-inserted into the atomizing chamber 210 during assembly, preventing the core tube 22 from being dislodged through the bottom of the atomizing chamber 210, thereby ensuring the precision of the assembly of the atomizing core 2. Furthermore, the atomizing chamber 210 forms a narrowing structure at the bottom of the seat tube portion 211 and the outer wall of the limiting structure 215, which facilitates the concentrated entry of airflow into the atomizing channel 231, thereby increasing airflow velocity and achieving a better atomization effect.

[0063] See also Figure 8 In some embodiments, the base body 21 is preferably further provided with two pin recesses 216 for limiting and fixing the two electrode pins 242 of the heating element 24. The two pin recesses 216 are both formed by the axial inward concave portion of the bottom of the sealing portion 212 and are respectively connected to the atomization chamber 210.

[0064] See also Figures 6 to 8 In some embodiments, a step surface 15 is radially provided on the inner wall surface of the shell 1 for positioning the sealing portion 212 of the card seat body 21 to prevent it from being over-inserted. The setting position of the step surface 15 is lower than the bottom end of the atomizing air guide tube 13, and the inner wall surface of the shell 1 above the step surface 15 constitutes one side wall of the atomizing chamber 11.

[0065] The base 21 also includes an annular gasket 217, which is preferably made of food-grade stainless steel to ensure that it is not corroded by tobacco oil. The annular gasket 217 is fixedly connected to the peripheral edge of the upper end surface of the sealing portion 212. When the atomizer core 2 is assembled inside the housing 1, the annular gasket 217 at least partially abuts the stepped surface 15, protecting the base 21 and preventing the silicone base 21 from excessive deformation or damage due to direct abutment with the stepped surface 15. This protects the base 21 and also ensures a tight seal between the sealing portion 212 of the base 21 and the inner wall of the housing 1.

[0066] When actually assembling the atomizing core 2, first wind the heating element 24 into a cylindrical shape and insert it into the atomizing channel 231 of the liquid guiding member 23, then insert the liquid guiding member 23 and the heating element 24 as a whole into the inner cavity of the core tube 22, and then insert the core tube 22, the liquid guiding member 23 and the heating element 24 as a whole through the opening at the upper end of the seat tube portion 211 until the bottom of the core tube 22 is inserted into the gap formed between the limiting structure 215 and the inner wall of the seat tube portion 211, so as to form the limitation and fixation of the core tube 22, and ensure that the second liquid inlet 221 on the core tube 22 can be at the same height as the first liquid inlet 213 on the seat tube portion 211 and communicate internally and externally. In addition, during assembly, the upper end surface of the limiting structure 215 can also be used to support and stop the liquid guiding member 23 to prevent the liquid guiding member 23 from slipping out of the lower opening of the seat tube portion 211. The two electrode pins 242 of the heating element 24 extend out from the bottom of the atomizing cavity 210 and are respectively inserted into the corresponding pin cavities 216 after being bent.

[0067] Please refer to Figure 1 , in some embodiments, the bottom cover 4 is preferably designed as a cover-like structure with an upward opening, having a cover bottom 41 and an arc-shaped cover side wall 42. The air inlet hole 411 is provided through the center position of the cover bottom 41 so that external air can enter the inner cavity of the housing 1 through the air inlet hole 411 and enter the atomizing channel 231 through the bottom opening of the atomizing cavity 210, thereby mixing with the aerosol generated by heating on the atomizing surface to form atomized gas. The atomized gas enters the atomizing air duct 13 through the opening at the top of the atomizing cavity 210 and finally exits from the air outlet hole 121 at the end of the mouthpiece 12.

[0068] An air inlet pipe portion 43 extending axially towards one end of the atomizing cavity 210 is further provided inside the bottom cover 4. The bottom end of the air inlet pipe portion 43 penetrates the cover bottom 41 to form the air inlet hole 411, and the top end of the air inlet pipe portion 43 is a dome-shaped structure with a number of micropores 431 for air flow. On the one hand, the air inlet pipe portion 43 forms a shield for the air inlet hole 411, so that a chamber capable of storing a certain amount of e-liquid is formed inside the bottom cover 4, which can prevent e-liquid from directly dripping onto the air inlet hole 411 when the liquid guiding member 23 has poor oil locking, and can also prevent the e-liquid accumulated in the bottom cover 4 from directly leaking out through the air inlet hole 411. On the other hand, it can also guide external air to enter the atomizing cavity 210 of the atomizing core 2 through each micropore 431.

[0069] Please refer to Figure 3 and Figure 9, in some embodiments, the bottom cover 4 is fixedly connected to the housing 1 through a positioning and clamping structure, and the bottom cover 4 can axially move from the first installation position to the second installation position. The preferred positioning and clamping structure includes a positioning clamping protrusion 421 provided on the outer wall surface of the cover side wall 42, and a positioning clamping groove 16 provided on the bottom side wall of the housing 1. Among them, the positioning clamping groove 16 includes a first positioning clamping groove 161 and a second positioning clamping groove 162 that are arranged at intervals up and down along the axis of the housing 1, and the first positioning clamping groove 161 is closer to the installation notch 11 at the bottom of the housing 1 than the second positioning clamping groove 162.

[0070] Preferably, there are two positioning clamping protrusions 421, which are symmetrically arranged on the outer wall surface of the cover side wall 42. Correspondingly, both the first positioning clamping groove 161 and the second positioning clamping groove 162 are provided with two, and are respectively symmetrically arranged on the bottom side wall of the housing 1. In order to prevent the bottom cover 4 from rotating during the process of moving from the first installation position to the second installation position, resulting in the positioning clamping protrusion 421 not being able to accurately engage with the positioning clamping groove 16, a guiding structure (not marked) is further provided between the outer wall surface of the cover side wall 42 and the inner wall surface of the housing 1.

[0071] Please refer to Figure 7 and Figure 9 , the guiding structure preferably includes at least one guiding rib 422 axially provided on the outer wall surface of the cover side wall 42, and a guiding groove 17 axially provided on the inner wall surface of the housing 1 and extending downward to the installation notch 11. When the bottom cover 4 is inserted into the housing 1 from the installation notch 11, the guiding rib 422 is movably inserted into the guiding groove 17 to guide the bottom cover 4 to axially move along the housing 1.

[0072] Please refer to Figure 3 and Figure 7 , when the atomizer product leaves the factory, the two positioning clamping protrusions 421 are respectively positioned and clamped on the two first positioning clamping grooves 161. At this time, the bottom cover 4 is in the first installation position and is pre-assembled at the bottom of the housing 1, and at least part of the bottom of the cover 41 extends downward out of the installation notch 11, and the extended length matches the axial distance between the first positioning clamping groove 161 and the second positioning clamping groove 162. At the same time, the closing member 3 closes the liquid inlet 20 of the atomization core 2 to achieve oil-core separation. After the user purchases the product, the bottom cover 4 can be manually pressed, and under the guidance of the guiding structure, the two positioning clamping protrusions 421 are disengaged from the first positioning clamping groove 161 and axially move to be clamped on the two positioning clamping grooves 16. At this time, the bottom cover 4 is in the second installation position and is assembled with the housing 1. At the same time, the driving member 44 drives the closing member 3 to axially move to expose the liquid inlet 20 to achieve oil-core conduction.

[0073] The upper end of the positioning card protrusion 421 is preferably provided with a wedge-shaped surface with a guiding function, which is conducive to the positioning card protrusion 421 disengaging from the first positioning card slot 161 and braking to the second positioning card slot 162, reducing the resistance when the user manually presses the bottom cover 4, and improving the operation convenience.

[0074] In some embodiments, the seat body 21 is an integrally formed structure made of plastic and is fixed to the housing 1 by ultrasonic welding or / and by laser welding. When the seat body 21 is provided as an integrally formed structure made of plastic, it can not only reduce the material cost and manufacturing cost of the seat body 21, but also realize the ultrasonic welding fixation or laser welding fixation between the seat body 21 and the housing 1. That is, the seat body 21 can be fixed to the housing 1 by using only the ultrasonic welding fixation method, or can be fixed to the housing 1 by using only the laser welding fixation method, or can be fixed to the housing 1 by using both the ultrasonic welding fixation method and the laser welding fixation method at the same time.

[0075] In this application, the seat body 21 is fixed on the housing 1 by ultrasonic welding and laser welding, which can achieve strict sealing between the two, and can eliminate the sealing parts such as oil cup silica gel, bracket silica gel, and bottom cover silica gel that are indispensable in the existing product design. While ensuring the overall sealing of the atomizer 10, it can significantly reduce the complexity of the atomizer 10, reduce costs, and improve the assembly efficiency at the same time.

[0076] In some embodiments, the seat body 21 is an integrally formed structure made of silica gel and is hermetically inserted into the housing 1 and is in interference fit with it. The silica gel seat body 21 itself has good elastic deformation and recovery ability. After being inserted and fixed into the housing 1, the opening at the top of its seat tube part 211 can be inserted and fixed on the bottom outer wall of the atomization guide pipe 13 in an interference fit manner to achieve good sealing. Preferably, a plurality of sealing ring parts (not marked) are circumferentially arranged on the inner wall surface at the top of the seat tube part 211. On the one hand, it can improve the sealing performance, and on the other hand, it can also increase the friction damping between the upper end of the seat tube part 211 and the atomization guide pipe 13, improving the reliability of their connection. The outer side wall surface of the sealing part 212 of the seat body 21 can be inserted and fixed on the inner wall surface of the housing 1 in an interference fit manner to achieve good sealing. In this way, the sealing parts such as oil cup silica gel, bracket silica gel, and bottom cover silica gel that are indispensable in the existing product design can be eliminated. While ensuring the overall sealing of the atomizer 10, it can significantly reduce the complexity of the atomizer 10, reduce costs, and improve the assembly efficiency at the same time.

[0077] For the atomizer 10 provided in this application, the driving member 44 on the bottom cover 4 can be directly connected to the closing member 3 or indirectly connected to the closing member 3. This application does not limit this, and it can ensure that when the bottom cover 4 is pre-assembled at the first installation position at the bottom of the housing 1, the closing member 3 can close the liquid inlet 20; when the bottom cover 4 is assembled at the second installation position at the bottom of the housing 1, the driving member 44 can drive the closing member 3 to axially move to expose the liquid inlet 20.

[0078] The first installation position is the pre-assembly position of the bottom cover 4 on the housing 1, and the second installation position is the assembly position of the bottom cover 4 on the housing 1. The height of the first installation position in the axial direction of the atomizer 10 is lower than that of the second installation position, so that the user can drive it from the first installation position to the second installation position by manually pressing the bottom cover 4, thereby driving the driving member 44 to move, so as to drive the closing member 3 to move to expose the liquid inlet 20 through the driving member 44.

[0079] Please refer to Figure 3 、 Figure 7 and Figure 9 In some embodiments, the driving member 44 includes at least one axially extending ejector rod 441. The ejector rod 441 is disposed in the bottom cover 4, and at least part of it movably passes through the seat body 21 outside the atomization chamber 210 and movably abuts against the sleeve 31, and the ejector rod 441 avoids the liquid inlet 20.

[0080] Preferably, there are two ejector rods 441, which are symmetrically arranged with the axis of the seat body 21 as the center, and are respectively located outside the area between the two first liquid inlets 213, so as to prevent the two ejector rods 441 from partially blocking the liquid inlet 20 after the bottom cover 4 is assembled on the housing 1 at the second installation position. In addition, the two symmetrically arranged ejector rods 441 can abut against the sleeve 31 from both sides, and can drive the sleeve 31 to stably move axially along the seat tube portion 211 to expose the liquid inlet 20, ensuring that the atomizer can be effectively activated.

[0081] Two ejector rod through holes 218 for the axial passing of the ejector rod 441 are symmetrically arranged on the seat body 21. The two ejector rod through holes 218 axially penetrate the sealing portion 212 from the outside of the seat tube portion 211, ensuring that at least part of the upper end surface of the ejector rod 441 can movably abut against the bottom peripheral edge of the sleeve 31.

[0082] The seat body 21 is preferably provided as an integral structure made of silica gel. The inner diameter of the ejector rod through-hole 218 matches the outer diameter of the ejector rod 441, so that the ejector rod 441 can be inserted into the ejector rod through-hole 218 in an interference fit manner, thereby using the elasticity of the seat body 21 to seal the gap between the two and prevent the atomization matrix from leaking out through the gap between the two. Preferably, a plurality of sealing ring parts (not marked) are circumferentially arranged on the inner wall surface of the ejector rod through-hole 218. On the one hand, it improves the sealing performance, and on the other hand, it can also increase the frictional damping between the ejector rod through-hole 218 and the ejector rod 441, preventing the ejector rod 441 from easily coming out of the ejector rod through-hole 218 due to transportation vibration or dropping and bumping before the user uses it, so as to avoid the atomization matrix in the liquid storage cavity from leaking out through the ejector rod through-hole 218.

[0083] When the bottom cover 4 is pre-assembled at the bottom of the housing 1 through the installation notch 11 at the first installation position, the sleeve 31 is sleeved on the lower end of the seat tube part 211 and closes the first liquid inlet 213 and the second liquid inlet 221. At this time, the upper end of the ejector rod 441 preferably extends to the bottom of the sleeve 31 through the ejector rod through-hole 218, and can be set to contact the sleeve 31 or there can be a little gap between it and the bottom of the sleeve 31. When the user manually presses the bottom cover 4 and drives it to axially move from the first installation position to the second installation position, the two ejector rods 441 move upward under the drive of the bottom cover 4 and lift the sleeve 31, so that the sleeve 31 axially moves along the seat tube part 211 to expose the first liquid inlet 213 and the second liquid inlet 221, realizing the conduction of the oil core.

[0084] For the atomizer 10 provided in this application, the ejector rod 441 is integrated onto the bottom cover 4. When the user manually presses the bottom cover 4 and axially moves it from the first installation position to the second installation position, the ejector rod 441 can be controlled to lift the sleeve 31 upward and expose the liquid inlet 20. While facilitating the activation operation of the atomizer, it simplifies the complexity of the internal structure of the atomizer, which is beneficial to reducing the production and manufacturing cost of the product. In addition, the driving member 44 is set as the ejector rod 441, which not only ensures that the driving member 44 can drive the closing member 3 to axially move to expose the liquid inlet 20, but also facilitates the overall assembly of the atomizer 10 and can realize automated production.

[0085] Please refer to Figure 3 and Figure 6, in some embodiments, the seat body 21 is provided as an integral structure of silica gel material. A ring groove 219 with an inverted L-shaped cross-section is provided at the peripheral edge of the bottom of the sealing portion 212. The diameter of the side wall of the ring groove 219 matches the inner diameter of the bottom cover 4, so that the upper end of the cover side wall 42 can be inserted into the bottom of the seat body 21 through the ring groove 219. When the bottom cover 4 is pre-assembled at the first installation position at the bottom of the housing 1, the upper end of the cover side wall 42 is not inserted into the ring groove 219; when the user manually presses the bottom cover 4 to axially move it from the first installation position to the second installation position, the upper end of the cover side wall 42 is inserted into the bottom of the seat body 21 through the ring groove 219. This structural design can, on the one hand, clamp and fix the cover side wall 42 of the bottom cover 4 on the housing 1 through the bottom of the silica gel seat body 21, improving the reliability of the connection and fixation between the bottom cover 4 and the housing 1. On the other hand, it can also use the cover side wall 42 to abut against the seat body 21, thereby integrally limiting and fixing the atomization core 2 in the housing 1 and ensuring the sealing of the liquid storage cavity 14.

[0086] Please refer to Figure 10 , in some embodiments of the present application, an electronic atomization device 100 is provided. The electronic atomization device 100 includes a main body 30 and the atomizer 10 described in any one of the above. An installation groove 6 is provided on the main body 30, and two main body electrodes 7 (one positive and one negative) are provided in the installation groove 6. A power supply module 8 electrically connected to the main body electrodes 7 is provided in the main body 30.

[0087] The atomizer 10 is detachably installed in the installation groove 6 according to a set insertion method. Two atomizer electrodes 5 (one positive and one negative) electrically connected to the two electrode pins 242 of the atomization core 2 are provided on the bottom cover 4. After the atomizer 10 and the main body 30 are assembled, the two atomizer electrodes 5 can correspondingly and movably abut against the two main body electrodes 7 and be electrically connected to the power supply module 8, so that the heating element 24 can do work and generate heat under the drive of the power of the power supply module 8 and atomize the e-liquid.

[0088] Please refer to Figure 8 and Figure 10 , in some embodiments, an air intake through hole 61 for air to enter is provided on the bottom surface of the installation groove 6, and a main body air intake hole 9 for external air to enter is provided at the bottom of the main body 30, and the main body air intake hole 9 communicates with the air intake through hole 61. When in use, the user sucks at the mouthpiece 12 of the atomizer 10 to generate negative pressure, so that external air can enter through the main body air intake hole 9 at the bottom of the main body 30, flow into the installation groove 6 through the air intake through hole 61, and then enter the bottom cover 4 through the air intake hole 411 of the atomizer 10, and thus enter the atomization channel 231 through the atomization cavity of the seat body 21, and be mixed with the aerosol generated by heating in the atomization channel 231 to form atomized gas, and finally be discharged through the atomization air duct 13 and the air outlet hole 121 for the user to inhale.

[0089] The electronic atomization device 100 provided by the present application has a replaceable atomizer 10. Before use, the bottom cover 4 of the atomizer 10 is pre-assembled at the bottom of the housing 1 at the first installation position, which can achieve the oil core separation state of the atomizer and avoid liquid leakage before use. When in use, manually press the bottom cover 4 to move it to the second installation position to activate the atomizer and achieve oil core conduction. Then, install the activated atomizer 10 into the installation slot 6 so that the atomizer electrode 5 contacts the main machine electrode 7, electrically connecting the power supply module 8 to the heating element 24. Thus, driven by the power of the power supply module 8, the heating element 24 does work and generates heat to heat and atomize the e-liquid. The structure is simple and the operation is convenient.

[0090] Please refer to Figure 1 , Figure 6 , Figure 8 and Figure 9 , in some embodiments, two electrode support portions 45 axially provided on the bottom cover 4 are respectively inserted into the corresponding pin cavities 216 of the seat body 21, and two electrode grooves (not labeled) are provided on the outer end surface of the bottom 41 of the cover. The two electrode grooves communicate with the inner cavity of the bottom cover 4 respectively. The bottom ends of the two atomizer electrodes 5 are respectively accommodated in the corresponding electrode grooves, and the other ends of the two atomizer electrodes 5 are inserted into the bottom cover 4 and respectively extend to the tops of the corresponding electrode support portions 45.

[0091] When the bottom cover 4 is pre-assembled at the bottom of the housing 1 at the first installation position, the electrode support portion 45 is not inserted into the pin cavity 216. At this time, the upper end of the atomizer electrode 5 does not contact the electrode pin 242 of the heating element 24. In this state, even if the pre-assembled atomizer 10 is inserted into the installation slot 6 and the atomizer electrode 5 abuts against the main machine electrode 7, the power supply module 8 and the heating element 24 cannot establish an electrical connection relationship, which can avoid dry burning of the heating element 24 in the pre-assembled state of the atomizer 10 and play a protective role.

[0092] When the bottom cover 4 is assembled at the bottom of the housing 1 at the second installation position, the electrode support portion 45 is inserted into the corresponding pin cavity 216, so that the tops of the two atomizer electrodes 5 abut against the two electrode pins 242 of the heating element 24, enabling the two electrode pins 242 of the heating element 24 to establish an electrical connection relationship with the two atomizer electrodes 5. In this state, after the atomizer 10 is installed in the installation slot 6, the two atomizer electrodes 5 correspondingly abut against the two main machine electrodes 7, enabling the two electrode pins 242 of the heating element 24 to establish an electrical connection relationship with the power supply module 8 through the atomizer electrodes 5 and the main machine electrodes 7, ensuring the normal use of the electronic atomization device 100.

[0093] In some other embodiments, the electrode support portion 45 and the atomizer electrode 5 may also be set as pin terminals, so that when the bottom cover 4 is assembled at the bottom of the housing 1 in the second installation position, the pin terminals are driven to be inserted into the corresponding pin cavities 216 to realize the electrical connection with the heating element 24. Additionally, the host electrode 7 may also be set as a pin terminal that cooperates with the atomizer electrode 5.

[0094] The above uses specific examples to elaborate on the technical solutions of the present application, which are only used to help understand the content of the present application and are not intended to limit the present application. For those skilled in the technical field to which the present application pertains, based on the idea of the present application, several simple deductions, deformations or substitutions can also be made.
