Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to a flavoring component, an atomizer, and an electronic atomization device. Background Technology

[0002] Atomizers typically consist of a reservoir and an atomizing component. The reservoir stores the liquid matrix, while the atomizing component heats up when powered to atomize the liquid matrix, producing an aerosol for the user to inhale. To enhance flavor, atomizers also include a flavoring component. During inhalation, the aerosol carries the aroma of the matrix source, which releases flavor compounds, as it flows through the flavoring component.

[0003] However, in the process of implementing the embodiments of this utility model, the inventors discovered that: currently, during inhalation, the airflow passes through the matrix source of the flavoring compound that can release fragrance, resulting in increased suction resistance, and the matrix source of the flavoring compound is consumed too quickly to match the volume of the liquid matrix, resulting in a poor consistency of aerosol taste in the later stage. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a flavoring component, atomizer, and electronic atomization device, which aims to solve the technical problems of increased draw resistance caused by airflow passing through the matrix source of the flavoring component that can release flavor compounds, and the excessively fast consumption rate of the matrix source of the flavoring compounds that cannot match the liquid matrix volume, resulting in poor consistency of aerosol taste in the later stage.

[0005] To solve the above-mentioned technical problems, the present invention provides a fragrance-enhancing component, including an air inlet, an air outlet, a liquid reservoir, and a porous body. The air inlet provides an airflow inlet for aerosols to enter the fragrance-enhancing component, and the air outlet provides an airflow outlet for aerosols to escape from the fragrance-enhancing component. The liquid reservoir stores a matrix source that can release fragrance compounds. The liquid reservoir is at least partially located between the air inlet and the air outlet. The porous body defines an airflow channel through which the aerosols flow. One end of the airflow channel is connected to the air inlet, and the other end is connected to the air outlet. The porous body contacts the liquid reservoir to guide at least a portion of the matrix source into the porous body.

[0011] Optionally, the flavoring component includes a mouthpiece, which is provided with the air outlet.

[0012] Optionally, the porous body includes an inlet end for the aerosol to enter the airflow channel and an outlet end for the aerosol to escape from the airflow channel. The outlet end extends into the nozzle to communicate with the outlet, and the outlet end is sealed to the nozzle.

[0013] Optionally, the nozzle is a soft rubber part, the porous body is a rigid part, and the air outlet is inserted into the nozzle by an interference fit.

[0014] Optionally, the flavoring component further includes a housing, which is detachably connected to the nozzle, and the porous body is detachably connected to the nozzle.

[0015] Optionally, the housing includes a positioning groove, and the end of the porous body away from the nozzle is inserted into the positioning groove.

[0016] Optionally, the bottom wall of the positioning groove is provided with an opening for guiding aerosol to the airflow channel.

[0017] Optionally, the flavoring component further includes a housing connected to the nozzle, the housing and the nozzle defining a storage cavity for receiving the liquid reservoir.

[0018] Optionally, the bottom wall of the storage cavity extends toward the nozzle with a mounting post, the mounting post defining a positioning groove for insertion of the porous body, the nozzle and the mounting post clamping the liquid storage component.

[0019] Optionally, the porous body may be made of porous ceramic.

[0020] Optionally, the number of both the porous body and the liquid storage element includes multiples, and the number of the porous body is the same as the number of the liquid storage element. Each liquid storage element is arranged around the porous body, and the multiple liquid storage elements are evenly arranged circumferentially.

[0021] To solve the above-mentioned technical problems, another technical solution adopted by this utility model is: to provide an atomizer, including the above-mentioned flavoring component and atomizing component, wherein the atomizing component can be connected to the flavoring component, the atomizing component includes a liquid storage chamber for storing a liquid matrix, and an atomizing element for atomizing the liquid matrix to generate an aerosol, wherein when the atomizing component is connected to the flavoring component, an air guiding channel is established between the atomizing component and the flavoring component to guide the aerosol into the flavoring component.

[0022] To solve the above-mentioned technical problems, another technical solution adopted by this utility model is to provide an electronic atomizing device, including the above-mentioned atomizer, and a power supply component for connecting with the atomizer and providing electrical energy to the atomizer.

[0023] In this embodiment of the invention, since the airflow flows through the airflow channel to the air outlet, and the matrix source and the airflow channel are located in different spaces, the airflow does not need to pass through the matrix source, making the airflow smooth and thus not affecting the suction resistance. Furthermore, since the porous body is in contact with the liquid storage device, at least part of the matrix source is guided into the porous body. Therefore, the aroma of the matrix source is slowly released through the capillary action of the porous body, so that the consumption rate of the matrix source is consistent with the consumption rate of the liquid matrix, thereby maintaining the consistency of the aerosol taste in the later stage.

[0027] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "locked" to another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1 and Figure 2 One embodiment of the present invention provides a fragrance enhancement component 10, including an air inlet 111, an air outlet 121, a liquid storage component 13, and a porous body 14. The air inlet 111 provides an airflow inlet for aerosols to enter the fragrance enhancement component 10, and the air outlet 121 provides an airflow outlet for aerosols to escape from the fragrance enhancement component 10. The liquid storage component 13 stores a matrix source that can release fragrance compounds. The liquid storage component 13 is at least partially located between the air inlet 111 and the air outlet 121. The porous body 14 defines an airflow channel 141 through which aerosols flow. One end of the airflow channel 141 is connected to the air inlet 111, and the other end is connected to the air outlet 121. The porous body 14 contacts the liquid storage component 13 to guide at least a portion of the matrix source into the porous body 14. In this embodiment of the invention, since the airflow flows through the airflow channel 141 to the air outlet 121, and the matrix source and the airflow channel 141 are located in different spaces, the airflow does not need to pass through the matrix source, making the airflow smooth and thus not affecting the suction resistance. Furthermore, since the porous body 14 is in contact with the liquid storage device 13, at least part of the matrix source is guided into the porous body 14. Therefore, the matrix source is slowly released through the capillary action of the porous body 14, so that the consumption rate of the matrix source is consistent with the consumption rate of the liquid matrix, thereby maintaining the consistency of the aerosol taste in the later stage.

[0030] In some embodiments, the liquid storage component 13 may be made of porous materials such as cotton fiber, non-woven fabric, or porous ceramics, so that the liquid storage component 13 can absorb and retain the matrix source described above through its internal micropores or pores. It is easy to understand that the matrix source is liquid, so that the matrix source can be impregnated and stored in the liquid storage component 13.

[0031] The matrix source may be a liquid containing tobacco substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. Flavorings may contain ingredients that can provide the user with various aromas or flavors. Vitamin mixtures may be mixtures containing at least one of vitamins A, B, C, and E, but are not limited to these. In some embodiments, the matrix source may be pre-injected into the reservoir 13, and then the reservoir 13 containing the matrix source is assembled into the flavoring component 10.

[0032] Alternatively, in some embodiments, bursting beads may be provided in the liquid storage device 13, and the matrix source is filled in the bursting beads. When in use, the bursting beads are squeezed and broken, at which time the matrix source can overflow and flow into and soak into the liquid storage device 13.

[0033] In some embodiments, such as Figure 2 As shown, the liquid storage component 13 surrounds the porous body 14 to increase the contact area between the liquid storage component 13 and the porous body 14.

[0034] In some embodiments, such as Figure 2 As shown, the airflow channel 141 passes through the liquid storage component 13 to prevent some aerosol from entering the liquid storage component 13 when flowing through the airflow channel, thereby preventing it from affecting the suction resistance.

[0035] In some embodiments, the porous body 14 is configured as a hollow tubular body, and the airflow channel 141 is defined by the hollow region of the tubular body.

[0036] It should be noted that the porous body 14 is preferably made of a rigid porous material, such as porous ceramics, porous cemented carbide, or porous glass. This allows the porous body 14 to possess a certain degree of rigidity, thereby maintaining the shape of the airflow channel 141 and preventing deformation of the airflow channel 141. In some embodiments, the porous body 14 is made of porous ceramic to reduce resistance to aerosols as they pass through the airflow channel 141.

[0037] In some embodiments, the tubular body may also be a rigid glass fiber tube with a microporous structure.

[0038] In some embodiments, the pore size of the porous body 14 is 5-10 μm, which gives the porous body 14 good capillary liquid conduction ability and liquid-locking and leak-proof ability.

[0039] In some embodiments, the porosity of the porous body 14 is 30-40%.

[0040] In some embodiments, please refer to Figure 1 and Figure 2 The flavoring component 10 includes a mouthpiece 12, which is provided with the aforementioned air outlet 121. The mouthpiece 12 is used for a user to hold in their mouth to draw in aerosol.

[0041] In some embodiments, please refer to Figure 2 The porous body 14 includes an inlet end 142 for aerosol to enter the airflow channel 141 and an outlet end 143 for aerosol to exit the airflow channel 141. The outlet end 143 extends into the nozzle 12 to communicate with the outlet 121, and the outlet end 143 is sealed with the nozzle 12 to prevent aerosol from leaking from the assembly gap between the porous body 14 and the nozzle 12.

[0042] In some embodiments, the nozzle 12 is a soft rubber part, the porous body 14 is a rigid part, and the air outlet 143 is inserted into the nozzle 12 by an interference fit. Specifically, the inner sidewall of the nozzle 12 and the outer sidewall of the porous body 14 elastically abut against each other.

[0043] In some embodiments, the nozzle 12 may be made of one of the following materials: silicone, rubber, latex, thermoplastic polyurethane, and thermoplastic elastomer.

[0044] In some embodiments, please refer to Figure 1 and Figure 2 The flavoring component 10 also includes a housing 15, which is detachably connected to the nozzle 12, and a porous body 14 which is detachably connected to the nozzle 12 to facilitate replacement or reuse of the porous body 14.

[0045] In some embodiments, please refer to Figure 2 The outer shell 15 and the suction nozzle 12 define a storage cavity 16 for accommodating the liquid reservoir 13. Thus, the liquid reservoir 13 can be exposed simply by separating the suction nozzle 12 from the outer shell 15, which facilitates the refilling of the liquid reservoir 13 or the replacement of the liquid reservoir 13.

[0046] In some embodiments, please refer to Figure 2 The nozzle 12 is partially inserted into the outer casing 15, and the outer side wall of the nozzle 12 elastically abuts against the inner wall of the outer casing 15, so that the nozzle 12 and the outer casing 15 are detachably connected. In addition, since the nozzle 12 is made of soft rubber, the outer side wall of the nozzle 12 elastically abuts against the inner wall of the outer casing 15 to seal the storage cavity 16.

[0047] It is understood that in some embodiments, the detachable connection between the nozzle 12 and the housing 15 is not limited to the above-described method. The detachable connection between the nozzle 12 and the housing 15 can be a magnetic connection structure, a snap-fit ​​structure, or other detachable connection structures.

[0048] It is understood that in some embodiments, the nozzle 12 is not limited to a soft rubber part, but is a rigid part. The flavoring component 10 also includes a first seal (not shown) for providing a seal between the nozzle 12 and the housing 15, thereby sealing the storage cavity 16. The air outlet 143 is inserted into the first seal by an interference fit.

[0049] In some embodiments, please refer to Figure 3 The outer casing 15 includes a positioning groove 151, and the end of the porous body 14 away from the nozzle 12 is inserted into the positioning groove 151 to position the porous body 14 during installation, thereby facilitating the alignment of the airflow channel 141. The end of the porous body 14 away from the nozzle 12 is the air inlet end 142 of the porous body 14.

[0050] Understandably, in some implementations, the end of the porous body 14 away from the nozzle 12 is detachably connected to the inner wall of the positioning groove 151 via a threaded or snap-fit ​​structure.

[0051] In some embodiments, please refer to Figure 3 The bottom wall of the positioning groove 151 is provided with an opening 152 for guiding aerosol to the airflow channel 141, that is, the opening 152 connects the airflow channel 141 and the air inlet 111.

[0052] In some embodiments, please refer to Figure 3 The bottom wall of the storage cavity 16 extends toward the nozzle 12 with a mounting post 153. The mounting post 153 defines a positioning groove 151 for insertion of the porous body 14. The nozzle 12 and the mounting post 153 clamp the liquid storage component 13 to fix the liquid storage component 13 and facilitate contact between the liquid storage component 13 and the porous body 14.

[0053] In some embodiments, the number of porous bodies 14 and liquid storage components 13 are both multiple, and the number of porous bodies 14 is the same as the number of liquid storage components 13. Each liquid storage component 13 is arranged around a porous body 14, and the multiple liquid storage components 13 are evenly arranged in the circumferential direction.

[0054] In some embodiments, please refer to Figure 2 The flavoring component 10 also includes a second seal 11, which provides a seal between the flavoring component 10 and the atomizing component 20 that provides the aerosol, and the second seal 11 is provided with the aforementioned air inlet 111.

[0055] In some embodiments, please refer to Figure 2 The flavoring component 10 also includes a liquid absorber 17. The second seal 11 and the outer shell 15 define a receiving cavity 18. The liquid absorber 17 is disposed in the receiving cavity 18 and is used to absorb condensate. The liquid absorber 17 is provided with an air guide port 171 that communicates with the air inlet 111 and the opening 152.

[0056] This utility model also provides an embodiment of an atomizer 100, please refer to [link / reference]. Figure 4 The atomizer 100 includes the flavoring component 10 and the atomizing component 20 described above. The atomizing component 20 can be connected to the flavoring component 10. The atomizing component 20 includes a liquid storage chamber 21 for storing a liquid matrix and an atomizing element 22 for atomizing the liquid matrix to generate an aerosol. When the atomizing component 20 is connected to the flavoring component 10, an air guiding channel 23 is established between the atomizing component 20 and the flavoring component 10 to guide the aerosol into the flavoring component 10. The structure and function of the flavoring component 10 can be referred to the above embodiments, and will not be described in detail here.

[0057] In this embodiment of the invention, when switching flavors, the user only needs to remove the original flavor-enhancing component 10 from the atomizing component 20 and then install the new flavor-enhancing component 10, making flavor switching convenient. Furthermore, since the flavor-enhancing component 10 and the atomizing component 20 are independent of each other, cross-contamination is prevented.

[0058] In some embodiments, please refer to Figure 4 The atomizing component 20 includes a liquid inlet 24, which connects to the liquid storage chamber 21 and is sealed by a second seal 11. The liquid inlet 24 is used to facilitate the user to replenish the liquid matrix into the liquid storage chamber 21. Specifically, during the replenishment of the liquid matrix, the flavoring component 10 is disassembled to open the liquid inlet 24, and then the liquid matrix is ​​replenished into the liquid storage chamber 21 through the liquid inlet 24.

[0059] This utility model also provides an embodiment of an electronic atomizing device 1000. Please refer to [link / reference]. Figure 5 It includes the aforementioned atomizer 100, and a power supply assembly 300 for connecting to the atomizer 100 and providing electrical power to the atomizer 100.

[0060] In an alternative implementation, for example Figure 5 As shown, the power supply assembly 300 includes a receiving cavity 310 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 320 at least partially exposed on the surface of the receiving cavity 310. The electrical contact 320 is used to form an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply assembly 300, thereby supplying power to the atomizer 100.

[0061] A third seal 330 is provided within the power supply assembly 300, and this third seal 330 divides at least a portion of the internal space of the power supply assembly 300 to form the aforementioned receiving cavity 310. Figure 5 In the preferred embodiment shown, the third seal 330 is configured to extend along the cross-sectional direction of the power assembly 300, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 310 from flowing into components such as the controller 340 and sensor 350 inside the power assembly 300.

[0062] exist Figure 5 In the preferred embodiment shown, the power supply assembly 300 further includes a battery cell 360 for power supply located at the other end of the receiving cavity 310 along its length, and a controller 340 disposed between the battery cell 360 and the receiving cavity 310, the controller 340 being operable to guide current between the battery cell 360 and the electrical contact 320.

[0063] In use, the power supply assembly 300 includes a sensor 350 for sensing the airflow generated when the user inhales through the atomizer 100, and then the controller 340 controls the battery cell 360 to output current to the atomizer 100 according to the detection signal of the sensor 350.

[0064] Further in Figure 5 In the preferred embodiment shown, the power supply assembly 300 has a charging unit 370 at the other end away from the receiving cavity 310 for charging the battery cell 360.
