Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, and more specifically, to an electronic atomizer and an electronic atomization device. Background Art

[0002] The atomizer core types of the electronic atomization products currently on the market generally use cotton core products or ceramic cores. When the atomizer core is working, the atomization liquid introduced through porous materials such as oil-conducting cotton or porous ceramics will be quickly heated on the heating components (such as metal wire, metal mesh, etc.) to generate aerosol.

[0003] However, under the existing technology and process conditions, the amount of aerosol generated by a single heating of a product with a single atomizer core has a low upper limit, which cannot meet the experience requirements of some customers. In order to increase the amount of aerosol, existing product solutions usually choose to increase the heating power. This method is prone to excessive heating temperature of the atomizer core, increasing harmful substances in the aerosol and shortening the product life.

[0004] At the same time, in order to meet regulatory and customer requirements, atomizer liquids are usually mixed liquids. The physical and chemical properties of the components in the mixed liquid are different. Products using a single atomizer core sometimes find it difficult to fully take into account the requirements of the atomization parameters of the components of the mixed liquid. Therefore, when atomizer products are used with certain atomizer liquids, the product experience is poor. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0027] The following is combined with Figures 1 to 6 And preferred embodiments further illustrate the utility model.

[0028] like Figures 1 to 4As shown, this embodiment discloses an electronic atomizer, including: a shell 11, which is formed with a accommodating cavity; an atomizing module 20, which is arranged in the accommodating cavity; wherein, the shell 11 includes a suction nozzle 12, and the atomizing module 20 divides the accommodating cavity into a first cavity 13 for storing atomized liquid and a second cavity 14 for storing atomized aerosol. The atomizing module 20 includes at least two atomizing cores 25, and the atomizing core 25 is used to atomize the atomized liquid guided out of the first cavity 13 to form an aerosol and then store it in the second cavity 14. The suction nozzle 12 includes an airway tube 121 for inhaling the aerosol, and the airway tube 121 is connected to the second cavity 14.

[0029] By setting at least two atomizer cores 25, the atomizer cores 25 are made of porous ceramics, which can greatly increase the amount and speed of aerosols generated by the electronic atomizer 10 during the atomization process, and in the case of failure of a single ceramic core 251, the electronic atomizer 10 can continue to work, reducing the overall failure risk of the product; and in order to meet regulations and customer requirements, the atomized liquid is usually a mixed liquid, and the physical and chemical properties of each component in the mixed liquid are different. The use of at least two atomizer cores 25 products can fully take into account the requirements of the various components of the mixed liquid for the atomization parameters. For atomized liquids with different physical and chemical properties, independent atomization parameter control can be used on different ceramic cores 251, thereby enhancing the compatibility of the product with the atomized liquid; at the same time, when the same amount of aerosol generation is required, the setting of at least two atomizer cores 25 is adopted, so that the temperature control range of each atomizer core 25 is looser, thereby extending the life of the atomizer core 25 and reducing the generation of harmful substances during the atomization process. For example, when the atomized liquid is smoke oil, excessively high temperatures are likely to produce harmful substances such as aldehydes and ketones.

[0030] In addition, the atomization module 20 divides the accommodating cavity into a first cavity 13 and a second cavity 14, which can not only effectively improve the space utilization rate of the accommodating cavity, further simplify the structure of the electronic atomizer 10, and further optimize the overall volume of the electronic atomizer 10; it can also further ensure the efficient operation of the atomization core 25, and the atomized liquid guided out of the first cavity 13 is directly atomized through the atomization core 25 to form an aerosol and then directly stored in the second cavity 14, without the need to be guided through a separate channel, so that the atomization process of the entire electronic atomizer 10 is faster and more efficient, better meeting the needs of users, and thereby effectively improving the user experience.

[0031] The housing 11 includes a bottom cover 15. The bottom cover 15 can well seal and clamp the end of the electronic atomizer 10, and facilitate the assembly of the atomizer module 20. After the atomizer module 20 is installed, the bottom cover 15 is used to clamp and achieve a sealing effect. The bottom cover 15 and the suction nozzle 12 are respectively arranged at both ends of the housing 11. The suction nozzle 12 is integrally formed with the housing 11. The suction nozzle 12 is arranged at one end close to the first cavity 13. The suction nozzle 12 is arranged close to the first cavity 13 to effectively reduce the atomization. The heat generated by the module 20 when working affects the user, thereby effectively improving the user's usage experience; the bottom cover 15, the side wall of the shell 11 and the top cover assembly 21 surround the second cavity 14, and the airway tube 121 passes through the first cavity 13 and is connected to the second cavity 14. When the user inhales the aerosol through the airway tube 121, the atomized liquid in the first cavity 13 can effectively cool the aerosol passing through the airway tube 121, better meet the user's needs for comfortable use, and thereby effectively improve the user's usage experience.

[0032] Among them, the atomization module 20 includes a top cover assembly 21, and the top cover assembly 21 and the bottom cover 15 are assembled in sequence. The top cover assembly 21 includes a silicone gasket 22, a top cover 23 and a silicone bracket 24. The top cover 23 is generally made of hard plastic or ceramic and other materials, which plays a supporting and limiting role, and can cooperate with the silicone pad and the silicone bracket 24 to achieve effective separation of the accommodating bin. Of course, the installation position of the atomization module 20 can be adjusted according to actual design needs, thereby adjusting the volume of the first cavity 13 and the second cavity 14 as needed to better meet the needs of different users; the silicone pad and the silicone bracket The racks 24 are respectively arranged on two opposite sides of the top cover 23, the silicone pad is arranged on one side of the first cavity 13, the silicone bracket 24 is arranged on one side of the second cavity 14, and the atomizer core 25 is arranged in cooperation with the silicone bracket 24. Through the arrangement of the silicone pad and the silicone bracket 24, the first cavity 13 and the second cavity 14 can be effectively sealed, and the atomized liquid in the first cavity 13 can be effectively prevented from leaking and seeping out. The silicone bracket 24 can also effectively cooperate with the top cover 23 to limit the atomizer core 25, and has very good high temperature resistance, which better ensures that the atomizer module 20 can work stably and efficiently.

[0033] Among them, the atomization core 25 includes a ceramic core 251, and the product of the ceramic core 251 has the advantage of stable quality; the ceramic core 251 is a porous ceramic core, and the ceramic core is set in a rectangular shape, which can effectively reduce the overall volume; the top cover assembly 21 is provided with a liquid conduction hole 211 connected to the first cavity 13, and the ceramic core 251 and the liquid conduction hole 211 are arranged one by one. One side of the ceramic core 251 is covered on the liquid conduction hole 211 of the silicone bracket 24, and each ceramic core 251 corresponds to a liquid conduction hole 211. By increasing the number of ceramic cores 251, the amount and speed of aerosols generated by the device during the atomization process are greatly increased. Of course, for atomization liquids with different physical and chemical properties, independent atomization parameter control can be used on different ceramic cores 251, thereby enhancing the compatibility of the electronic atomizer 10 with the atomization liquid.

[0034] The atomization module 20 includes electrodes 26 and an atomization core 25 arranged in pairs. One end of the electrode 26 is fixed on the bottom cover 15. A heating film layer 252 or a metal patch is provided on the other side of the ceramic core 251. When the ceramic core product is working, the atomized liquid introduced through the ceramic matrix of the ceramic core 251 is quickly heated on the heating component (such as a metal patch, a heating film, etc.). The atomized liquid is atomized into an aerosol in this process. Two contact points 253 are provided on the heating film layer 252 or the metal patch. The other end of the electrode 26 is connected to the contact point 253. 53 contacts to form an electrical connection. When the electronic atomizer 10 is powered on and working, the contact points 253 at both ends of the metal patch or the heating film layer 252 will contact the two electrodes 26 respectively to form an electrical connection, so that the metal patch or the heating film layer 252 is heated, and the atomized liquid in the first cavity 13 is guided into the porous atomization core 25 for atomization to form an aerosol and then stored in the second cavity 14; the heating circuit corresponding to each ceramic core 251 can be independently controlled, and of course the design can be simplified by directly merging them for unified control, such as in parallel or series.

[0035] Among them, a first window 27 for observing the remaining amount of atomized liquid is provided on the shell 11 corresponding to the first cavity 13. The first window 27 is made of transparent material. The first window 27 made of transparent material can make it more convenient for users to observe the remaining amount of atomized liquid, reminding users to replace it in time or prepare stock as soon as possible, thereby effectively improving the user experience.

[0036] Specifically, the housing 11, silicone gasket 22, top cover 23, silicone bracket 24, and ceramic core 251 of the electronic atomizer 10 are assembled in sequence to form a first cavity 13, in which atomized liquid is stored. Four electrodes 26 are installed on the bottom cover 15, and the bottom cover 15 with the electrodes 26 is assembled with the aforementioned components to complete the device assembly of the electronic atomizer 10; the bottom cover 15, top cover 23, silicone bracket 24, ceramic core 251 and the side wall of the housing 11 form a second cavity 14 for storing atomized aerosol.

[0037] After the electronic atomizer 10 is assembled, the four electrodes 26 are respectively in contact with the two contact points 253 of the two atomizer cores 25 to form an electrical connection. At the same time, the four electrodes 26 are also exposed after passing through the bottom cover 15 to connect with the control circuit of the control unit 31 of the electronic atomizer device 30 during operation.

[0038] like Figure 3 As shown, a schematic diagram of the structure of a single atomizer core 25. A metal patch or heating film layer 252 is attached to the porous ceramic substrate. After assembly, the two ends of the metal patch or heating film layer 252 will contact the two electrodes 26 respectively to form an electrical connection. When working, the two electrodes 26 are energized, so that the metal patch or heating film layer 252 heats up. Figure 3 This is for illustration only and does not mean that the atomizer cores 25 in the same product all have the same specifications. In technical implementation, the same electronic atomizer 10 may use atomizer cores 25 of different specifications.

[0039] When the electronic atomizer 10 is working, the external circuit inputs current from the electrode 26, and heats the ceramic core 251 through the current loop. The ceramic core 251 quickly heats the atomized liquid guided out from the first cavity 13 through the ceramic matrix, and forms an aerosol in the second cavity 14. The aerosol is released from the second cavity 14 through the airway tube 121 on the nozzle 12 of the electronic atomizer 10 to the outside.

[0040] In order to further increase the flexibility of the application of the present technology, in this embodiment, a partition 131 is optionally provided in the first cavity 13, and the partition 131 divides the first cavity 13 into at least two separate compartments 132 for storing the atomized liquid and being independent of each other, and each compartment 132 is provided with at least one ceramic core 251; Figure 5As shown, in application, the first cavity 13 can be divided to provide an independent partition chamber 132 for each ceramic core 251, and the same or different atomizing liquids can be filled in different partition chambers 132. The first cavity 13 is divided into two independent partition chambers 132, and the atomizing liquids in the two partition chambers 132 are independently supplied to the corresponding atomizing cores 25. For atomizing liquids with different physical and chemical properties, independent atomization parameter control can be used in different ceramic cores 251, which enhances the compatibility of the product with the atomizing liquid. At the same time, the aerosol particle size distribution and composition distribution can be optimized by controlling the combined parameters.

[0041] like Figure 6 As shown, another embodiment of the utility model is an electronic atomization device 30, which includes a control unit 31 and the above-mentioned electronic atomizer 10. The control unit 31 is electrically connected to the atomization module 20. The control unit 31 includes a power supply 32 and a main control board 33. The main control board 33 is electrically connected to the power supply 32, and the electrodes on the atomization module are exposed after passing through the bottom cover, so that it is convenient to electrically connect with the control circuit of the control unit 31 of the electronic atomization device 30 during operation. Of course, the controls can also be combined in a simplified design, such as in parallel or series.

[0042] The main control board 33 includes a plurality of independent control circuits, each of which is electrically connected to an atomizer core. When the electronic atomizer 10 is working, different current loops can be electrically controlled independently. In some scenarios, the current loops can also be connected in series or in parallel to reduce the difficulty of implementation and manufacturing costs. In actual products, the electronic atomizer 10 and the control unit 31 can be detachably fixedly connected to facilitate separation from each other to make a cartridge-changing product; they can also be integrally molded together to make an integrated product.

[0043] For atomizing liquids with different physical and chemical properties, in the electronic atomizer 10, an independent separation chamber can be provided for each ceramic core for atomizing liquid supply, and independent control circuits can be used for atomizing parameter control in different ceramic cores, thereby enhancing the compatibility of the electronic atomizer 10 with the atomizing liquid. At the same time, the atomizing parameters of different atomizing cores can be controlled in combination to optimize the aerosol particle size distribution and component distribution. By using multiple atomizing cores, the atomizing liquid can also produce aerosols under different atomization conditions in the single-chamber mode, and different atomizing liquids can be matched in the multi-chamber mode. In a simplified design, independent liquid chambers can also be merged, and at most merged into a single liquid chamber.

[0044] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
