Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and particularly relates to an atomizer and an electronic atomization device. Background Technology

[0002] Currently, pre-filled liquid atomizers on the market commonly suffer from leakage problems, which not only affect user experience but may also damage the device. To address this issue, some manufacturers have adopted an open design solution, meaning they do not pre-fill liquid at the factory, allowing consumers to add it themselves. However, surveys show that most users still prefer ready-to-use pre-filled products.

[0003] Among the leakage problems of pre-filled atomizers, leakage from the atomizer coil is particularly prominent. This is closely related to the fact that they must use porous liquid guiding structures (such as liquid guiding cotton or porous ceramics) to deliver the atomized liquid to the heating element. Traditional pre-filled atomizers usually use a movable leak-proof structure with "liquid-coil separation". Although this design can effectively isolate the atomized liquid from the atomizer coil, it also has obvious drawbacks: First, it significantly increases the complexity of the product structure; second, it requires additional operating steps before use; more importantly, because it takes a certain amount of time for the atomized liquid to flow to the surface of the heating element, it is prone to draw delay problems, and even if the user uses it improperly, it can easily lead to dry burning and scorching of the coil. Utility Model Content

[0004] The purpose of this application is to provide an atomizer and an electronic atomizing device to solve the technical problem that pre-filled liquid atomizers in the prior art are prone to leakage.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide an atomizer, wherein a liquid injection hole is provided on the top of the atomizer, and a sealing assembly is also provided on the atomizer, the sealing assembly comprising: A liquid injection plug is used to seal the liquid injection hole on the atomizer; A bottom plug is used to seal the bottom opening of the atomizer; An airway plug is used to block the output airway of the atomizer. The airway plug includes a retaining sleeve and an extension rod detachably connected to the retaining sleeve. The retaining sleeve is disposed inside the atomizer, and the extension rod extends from the atomizer for removal by hand to open the output airway.

[0006] This allows the atomizer's filling port to be located at the top of the atomizer, ensuring it remains upright during filling. The sealing assembly, consisting of the airway plug, filling plug, and bottom plug, forms a triple-seal structure, allowing the injected liquid to pre-wet the coil. This pre-wetting of the coil means that the output airway can be opened immediately after removing the extension rod of the airway plug, eliminating the need for waiting and effectively avoiding the risk of dry burning during first use. This also solves the draw delay defect of traditional atomizers.

[0007] In one embodiment, the extension rod includes a fixed end and an extension end at both ends. The fixed end is connected to the opening of the fixing sleeve, and the connection between the fixed end and the fixing sleeve has a pull-out structure. The extension end extends out of the atomizer. Thus, during use, the user can easily remove the extension rod with slight pulling force to open the atomizer's airflow path, making it convenient to use.

[0008] In one embodiment, the injection plug includes a connector and a plurality of first plugs, the same number as the number of injection holes, wherein the plurality of first plugs are connected to the same end face of the connector. Thus, the injection plug employs an integrated multi-plug structure, which facilitates adaptation to the multi-injection hole structure of the atomizer, ensuring sealing performance while also meeting the requirements of modern automated production lines.

[0009] The atomizer's structure is improved, further comprising a mouthpiece, an upper shell, a base, and an atomizing coil. The upper shell is connected to the base. The atomizer's output airway is formed on the upper shell, and the liquid filling hole is also located on the upper shell. The mouthpiece is mounted on the upper shell and communicates with the output airway, housing the liquid filling plug that seals the liquid filling hole. A bottom plug is mounted on the outer surface of the base. The atomizing coil is disposed on the base and connected to the output airway inside the upper shell. A retaining sleeve for the airway plug is located at the connection between the atomizing coil and the output airway, and an extension rod of the airway plug extends outward from the mouthpiece along the output airway. This creates a triple-sealing structure for the atomizer, allowing the atomized liquid injected into the atomizer to flow into the atomizing coil, pre-wetting it. This enables the atomizer to be used immediately after removing the extension rod of the airway plug, opening the output airway without waiting, effectively avoiding the risk of dry burning during first use and solving the draw delay defect of traditional atomizers.

[0010] The structure of the output airway is improved. The output airway has a socket located inside the atomizer for connection with the atomizing core, and a retaining sleeve for the airway plug is disposed in the socket. The retaining sleeve has an outer convex ring and an inner convex ring. The outer convex ring abuts against the inner wall of the socket, and the inner convex ring abuts against the outer wall of the atomizing core. Thus, by adding outer and inner convex rings to the retaining sleeve of the airway plug, a multi-convex ring coupling structure is formed, which helps to ensure the contact strength with the socket of the output airway and the outer wall of the atomizing core, improving the fixing effect and sealing performance.

[0011] In one embodiment, the fixing sleeve is further provided with an outwardly bent buckle, which is fastened to the wall of the socket to ensure the positioning effect of the airway plug and improve the sealing of the connection between the output airway and the atomizing core.

[0012] The structure of the upper shell is improved by providing a receiving groove for accommodating the injection plug, with the injection hole located within the receiving groove. This allows the injection plug to be embedded within the receiving groove of the upper shell, and after the suction nozzle is attached, the injection plug and injection hole are completely sealed, reducing space occupation and ensuring a good seal.

[0013] In one embodiment, the outer periphery of the upper shell is provided with a retaining rib, and the suction nozzle has a surrounding portion extending to the outer periphery of the upper shell, the surrounding portion having a retaining groove that engages with the retaining rib. This allows the suction nozzle to be installed and secured without auxiliary tools, effectively preventing it from being pried open by external force under normal usage conditions.

[0014] The base structure is improved, with at least two air holes communicating with the interior of the atomizer on its outer surface. The bottom plug includes a cover and second plugs disposed on the cover, the number of which is the same as the number of air holes. The cover is used to cover the outer surface of the base, simultaneously allowing each second plug to be inserted into each air hole to form a multi-hole synchronous sealing structure. This facilitates locking the installation orientation of the bottom plug, improving operational efficiency. The cover structure on the bottom plug increases the coverage area of ​​the atomizer bottom and allows the user to easily operate the cover when removing the bottom plug, simultaneously separating the second plugs from each air hole, thereby improving the convenience of bottom plug removal.

[0015] Secondly, embodiments of this application also provide an electronic atomizing device, including a main body, a power supply component, and the atomizer, wherein the atomizer is detachably connected to the main body; when the atomizer is installed on the main body, the extension rod of the airway plug and the bottom plug are removed from the atomizer; the power supply component is disposed within the main body, and the power supply component includes a circuit board and a battery for supplying power to the atomizer; the atomizing core in the atomizer includes at least a heating element, and the heating element is electrically connected to the circuit board. Thus, the atomizer can be used as a replaceable part; when the atomizing liquid in the atomizer is depleted, the atomizer can be removed from the main body and a new atomizer can be installed, effectively achieving rapid battery life.

[0016] The beneficial effects of the atomizer and electronic atomization device provided in this application are as follows: Compared with the prior art, this application improves the sealing component applied to the pre-filled atomizer, allowing the filling hole to be opened at the top of the atomizer, so that the atomizer can maintain an upright position for filling. Compared with the traditional inverted filling structure, forward filling helps to improve the accuracy of the filling volume, avoids liquid backflow or overflow, and is beneficial for operation on automated filling equipment.

[0017] The sealing assembly of this atomizer includes an airway plug, a liquid filling plug, and a bottom plug. The airway plug prevents the atomized liquid entering the atomizer coil from leaking out of the atomizer's output airway. The liquid filling plug seals the liquid filling hole, and the bottom plug seals the bottom opening of the atomizer. This creates a triple-seal structure for the atomizer, effectively sealing areas prone to leakage. Therefore, during the liquid filling and packaging storage stages, the atomizer of this application allows the injected atomized liquid to pre-wet the atomizer coil. When in use, removing the extension rod of the airway plug opens the output airway, allowing immediate use without waiting. This effectively avoids the risk of dry burning during first use, ensuring consistent atomization performance, solving the draw delay defect of traditional atomizers, and thus improving the user experience.

Detailed Implementation

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] Traditional atomizer leakage problems mainly occur in two key stages: the liquid filling stage during production and the initial use by the consumer. Related technologies typically employ a bottom-filling method, utilizing gravity to invert the atomizer for filling. By controlling the liquid volume to not exceed the liquid inlet on the atomizer coil and using the positive internal pressure generated during filling, leakage through the atomizer coil and mouthpiece is prevented.

[0026] The aforementioned inverted liquid-filling atomizers generally employ a design with an openable and closable liquid inlet to further prevent leakage. A common design involves an external pressing mechanism on the atomizer, which moves the atomizer coil up and down inside the atomizer. A mounting bracket then blocks the outer periphery of the coil, controlling the opening and closing of the liquid inlet. Maintaining a closed inlet at the factory effectively prevents leakage during storage. However, this design requires manual opening of the liquid inlet before use, resulting in a prolonged process of liquid soaking into the coil and potentially causing delayed vaping during initial use.

[0027] A common solution to the aforementioned draw delay problem is to install a sealing cap at the mouthpiece to pre-wet the atomizer coil with the e-liquid. However, opening the sealing cap can easily cause leakage. Therefore, while the aforementioned technology, which involves filling the atomizer with liquid at the bottom, can solve some of the leakage problems, it still cannot effectively overcome the draw delay defect in the initial stage of use.

[0028] Therefore, this application provides a novel atomizer and electronic atomization device, which redesigns the liquid filling structure and sealing components of the pre-filled atomizer. This design helps to effectively seal the atomizer during the three stages of liquid filling, packaging and storage, and use, thereby solving the problem of leakage that is common in traditional pre-filled atomizers. A detailed description follows.

[0029] Please see Figure 1 A liquid injection hole 101 is provided on the top of an atomizer 100 so that the atomizer 100 can be set in an upright position during the pre-liquid injection stage, allowing the injection needle on the injection machine to extend into the atomizer 100 through the liquid injection hole 101 on the top of the atomizer 100 to inject liquid into the atomizer 100.

[0030] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The atomizer 100 is also provided with a sealing assembly as described in this embodiment of the application. The sealing assembly includes an airway plug 1, a liquid injection plug 2, and a bottom plug 3. Preferably, the airway plug 1, the liquid injection plug 2, and the bottom plug 3 are all preferably made of silicone material, which gives them excellent elasticity and sealing performance.

[0031] The injection plug 2 is used to be installed on the injection port 101 of the atomizer 100 after injection to seal the injection port 101.

[0032] The bottom plug 3 is installed on the bottom of the atomizer 100 during the filling stage and packaging storage to seal the bottom opening of the atomizer 100, thereby preventing the atomized liquid flowing into the atomizer coil from easily leaking from the bottom opening of the atomizer 100. The bottom plug 3 is removed only when the atomizer 100 is installed on the main body of the electronic atomizing device for connection to the main body.

[0033] Please refer to the following: Figure 2 and Figure 3 The airway plug 1 is used to block the output airway 102 of the atomizer 100. This output airway 102 is connected to the mouthpiece on the atomizer 100. During use, the aerosol generated by the atomizing coil will be output from the output airway 102 and the mouthpiece. Figure 3 As shown, the airway plug 1 includes a retaining sleeve 11 and an extension rod 12 detachably connected to the retaining sleeve 11. The retaining sleeve 11 is located inside the atomizer 100 and is used to seal the connection between the output airway 102 and the atomizing coil, ensuring that the generated aerosol can be smoothly output from the output airway 102. The extension rod 12 is plugged into the opening on the retaining sleeve 11 and extends out of the atomizer 100. Before using the atomizer 100, the extension rod 12 can be manually removed to open the output airway 102.

[0034] Compared with the prior art, the nebulizer 100 provided in this application embodiment improves the sealing component applied to the pre-filled nebulizer 100, allowing the filling hole 101 to be opened at the top of the nebulizer 100, so that the nebulizer 100 can maintain an upright position for filling. Compared with the traditional inverted filling structure, forward filling is beneficial to improving the accuracy of the filling volume, avoiding liquid backflow or overflow, and is beneficial to operation on automated filling equipment.

[0035] In this embodiment, the sealing assembly on the atomizer 100 includes an airway plug 1, a liquid filling plug 2, and a bottom plug 3. The airway plug 1 prevents the atomized liquid entering the atomizing core from leaking from the output airway 102 of the atomizer 100. The liquid filling plug 2 blocks the liquid filling hole 101, and the bottom plug 3 blocks the bottom opening of the atomizer 100. This creates a triple-sealing structure for the atomizer 100, effectively sealing areas prone to leakage. Therefore, during the liquid filling and packaging storage stages, the atomizer 100 of this embodiment allows the injected atomized liquid to pre-flow into the atomizing core, pre-wetting it. When in use, removing the extension rod 12 of the airway plug 1 opens the output airway 102, allowing immediate use without waiting. This effectively avoids the risk of dry burning during first use, ensuring consistent atomization performance and resolving the draw delay defect of traditional atomizers 100, thereby improving the user experience.

[0036] The sealing component on the atomizer 100 in this embodiment can achieve phased dynamic sealing of the atomizer 100, achieving a perfect balance between liquid injection efficiency, storage and transportation safety and user experience. It is particularly suitable for use on pre-filled atomizers 100 that require long-distance transportation and long-term storage.

[0037] For the structure of the airway plug 1, please refer to one embodiment of this application. Figure 4 and Figure 5 The extension rod 12 of the airway plug 1 has a fixed end 121 and an extension end 122 at both ends. The fixed end 121 of the extension rod 12 is used to connect to the sleeve opening of the fixed sleeve 11, and the connection between the fixed end 121 and the fixed sleeve 11 has a breakable structure. The extension end 122 of the extension rod 12 extends outside the atomizer 100 so that the extension rod 12 can be removed by hand.

[0038] The connection between the fixed end 121 of the extension rod 12 and the fixed sleeve 11 can preferably adopt a fracture groove structure so that the user can remove the extension rod 12 with a little pulling force, thereby making the fixed sleeve 11 conductive and opening the output air passage 102 of the atomizer 100 for convenient use.

[0039] The injection plug 2 in this embodiment is preferably a silicone plug, which facilitates sealing the injection hole 101 through an interference fit. The specific structure of the injection plug 2 includes, but is not limited to, the following forms: In one embodiment of this application, please refer to the following: Figure 6 and Figure 7 The injection plug 2 includes a connector 21 and a plurality of first plugs 22, which are the same number as the injection holes 101. The plurality of first plugs 22 are connected to the same end face of the connector 21.

[0040] In this embodiment, as Figure 6 and Figure 7 As shown, the top of the atomizer 100 has two symmetrically positioned injection holes 101, which facilitates adaptation to the injection end of the injection device. This can be understood as the injection end of the injection device being a pair of parallel injection needles that can be simultaneously inserted into the two injection holes 101 of the atomizer 100 to inject liquid into the atomizer 100, thereby improving the uniformity of the atomized liquid inside the atomizer 100.

[0041] The connector 21 of the liquid injection plug 2 is a ring body with two first plugs 22 symmetrically arranged on the ring body. When the connector 21 is installed on the atomizer 100, the two first plugs 22 will automatically align with the two liquid injection holes 101 and be inserted into the liquid injection holes 101 of the atomizer 100 at the same time, so as to achieve synchronous sealing of the two liquid injection holes 101 and effectively improve the operating efficiency.

[0042] Therefore, the liquid filling plug 2 adopts a multi-plug integrated structure, which is conducive to adapting to the multi-liquid filling hole 101 structure on the atomizer 100. It not only ensures the sealing performance, but also adapts to the needs of modern automated production lines, achieving a dual improvement in production efficiency and quality. It is especially suitable for mass production of pre-liquid filling atomizers 100.

[0043] In another embodiment of this application (not shown in the figure), multiple liquid injection plugs 2 may be provided according to the number of liquid injection holes 101 on the atomizer 100, and these liquid injection plugs 2 may be installed on each liquid injection hole 101 respectively.

[0044] This allows the injection plug 2 to be set independently, which facilitates the flexible opening and closing of the injection hole 101 to meet the needs of injection and pressure relief.

[0045] Please refer to the following: Figure 1 , Figure 3 and Figure 8 This application embodiment also provides an atomizer 100, including an upper shell 4, a base 5, a mouthpiece 6, an atomizing core 7, and the sealing assembly provided in the above-mentioned application embodiment. The upper shell 4 and the base 5 are connected to form the atomizer 100.

[0046] The liquid injection hole 101 is opened on the upper shell 4 and is located at the top of the entire atomizer 100, which is conducive to the atomizer 100 being injected in an upright position.

[0047] The output air passage 102 of the atomizer 100 is formed on the upper shell 4. The nozzle 6 is installed on the upper shell 4 and communicates with the output air passage 102. It also houses the liquid filling plug 2 that is sealed on the liquid filling hole 101, thereby covering and protecting the liquid filling hole 101 and the liquid filling plug 2.

[0048] The atomizing core 7 is mounted on the base 5 and connected to the output air channel 102 inside the upper shell 4. The upper shell 4 and the base 5 enclose a liquid storage chamber 103 outside the atomizing core 7. The atomizing liquid injected through the injection hole 101 will be stored in the liquid storage chamber 103. The outer peripheral wall of the atomizing core 7 has a liquid inlet hole, through which the atomizing liquid in the liquid storage chamber 103 can enter the atomizing core 7.

[0049] The fixing sleeve 11 of the airway plug 1 is set at the connection between the atomizing core 7 and the output airway 102, and seals the connection to prevent the generation of aerosols or the cross-flow of atomizing liquid in the liquid storage chamber 103.

[0050] The extension rod 12 of the airway plug 1 extends out of the nozzle 6 along the output airway 102 so that the user can remove the extension rod 12 during use to open the output airway 102.

[0051] The bottom plug 3 is installed on the outer surface of the base 5 to seal the bottom opening of the atomizer 100.

[0052] In this way, the nozzle 6 covers and protects the injection hole 101 and the injection plug 2, eliminating the risk of leakage from the injection hole 101 on the atomizer 100 after injection. The bottom plug 3 seals the bottom of the atomizer 100. The fixing sleeve 11 of the airway plug 1 seals the connection between the output airway 102 and the atomizing core 7. The extension rod 12 of the airway plug 1 extends out from the output airway 102 and the nozzle 6. During use, the output airway 102 can be opened by removing the extension rod 12. As can be seen, this triple sealing structure provides sealing protection for the atomizer 100, allowing the atomizing liquid injected into the atomizer 100 to flow into the atomizing core 7 and pre-wet the atomizing core 7. This enables the atomizer 100 to be used immediately after removing the extension rod 12 of the airway plug 1 and opening the output airway 102, without waiting. This effectively avoids the risk of dry burning during first use, ensures consistent atomization effect, solves the draw delay defect of traditional atomizers 100, and improves the user experience.

[0053] Regarding the connection between the output air passage 102 and the atomizing core 7, please refer to one embodiment of this application. Figure 3 and Figure 8 The output airway 102 has a socket 104 located inside the atomizer 100 for connection with the atomizing core 7. The fixing sleeve 11 of the airway plug 1 is disposed in the socket 104 so that the end of the atomizing core 7 is inserted into the fixing sleeve 11. The fixing sleeve 11 seals between the end of the atomizing core 7 and the socket 104 of the output airway 102.

[0054] The fixing sleeve 11 is provided with an outer protruding ring 111 and an inner protruding ring 112. The outer protruding ring 111 abuts against the inner wall of the socket 104, and the inner protruding ring 112 abuts against the outer wall of the atomizing core 7.

[0055] In this embodiment, the outer wall of the fixing sleeve 11 is provided with multiple outer protruding rings 111, each of which abuts against the inner wall of the socket 104. Similarly, the inner wall of the fixing sleeve 11 is provided with multiple inner protruding rings 112, each of which abuts against the outer wall of the connecting end of the atomizing core 7. Preferably, these outer protruding rings 111 and inner protruding rings 112 can be staggered on the fixing sleeve 11 to increase the coverage area.

[0056] Therefore, an outer convex ring 111 and an inner convex ring 112 are added to the fixing sleeve 11 of the airway plug 1, thereby forming a multi-convex ring coupling structure. On the one hand, this helps to ensure the contact strength with the socket 104 of the output airway 102 and the outer wall of the atomizing core 7, improving the fixing effect and sealing performance. On the other hand, it helps to adapt to the dimensional deviations of the connection parts, improving the connection compatibility between components.

[0057] Based on the above, please refer to the embodiments in this application as well. Figure 3 and Figure 8 The fixing sleeve 11 is also provided with an outwardly bent buckle 113, which is fastened to the wall of the socket 104.

[0058] During the assembly of the atomizer 100, the airway plug 1 can be installed inside the upper shell 4 first, and the retaining sleeve 11 can be placed on the socket 104 of the output airway 102 so that the extension rod 12 passes through the output airway 102 and extends out of the upper shell 4. The fastening edge 113 on the retaining sleeve 11 is fastened to the wall of the socket 104 to ensure the positioning effect of the airway plug 1 and improve the sealing of the connection between the output airway 102 and the atomizing core 7.

[0059] Regarding the structure of the upper shell 4, please refer to one embodiment of this application. Figure 9 The upper shell 4 is also provided with a receiving groove 41 for accommodating the liquid injection plug 2, and the liquid injection hole 101 is opened in the receiving groove 41.

[0060] In this embodiment, the injection plug 2 is preferably a ring structure with two first plugs 22 on the ring for insertion into the two injection holes 101 respectively. Correspondingly, the receiving groove 41 on the upper shell 4 matches the shape of the injection plug 2, and the receiving groove 41 is preferably an annular groove surrounding the outer periphery of the output air passage 102.

[0061] In this way, the injection plug 2 can be embedded in the receiving groove 41 of the upper shell 4, and after the suction nozzle 6 is installed, the injection plug 2 and the injection hole 101 are completely sealed, effectively improving the sealing effect. In addition, the groove structure of the receiving groove 41 can effectively position the injection plug 2, which helps to reduce the space occupied and improve the fixing effect.

[0062] For the fixing structure of the upper shell 4 and the suction nozzle 6, please refer to another embodiment of this application. Figure 3 , Figure 9 and Figure 10 The upper shell 4 has a buckle 42 on its outer periphery, and the suction nozzle 6 has a surrounding part 61 extending to the outer periphery of the upper shell 4. The surrounding part 61 has a buckle groove 62 that engages with the buckle 42.

[0063] In this embodiment, the outer periphery of the upper shell 4 has at least one ring of raised retaining ribs 42. Correspondingly, the connection end of the nozzle 6 and the upper shell 4 has a surrounding portion 61 that can extend to the outer periphery of the upper shell 4. The inner wall of this surrounding portion 61 is provided with the same number of retaining grooves 62 as the retaining ribs 42. When the nozzle 6 is installed on the upper shell 4, the retaining grooves 62 and retaining ribs 42 are engaged to complete the installation and fixation of the nozzle 6 without the need for auxiliary tools, effectively preventing external force from prying it open in normal use scenarios and ensuring a sealing effect.

[0064] For the mounting structure of the base 5 and the bottom plug 3, please refer to one embodiment of this application. Figure 11 and Figure 12 The outer surface of the base 5 has at least two air holes 51 that communicate with the interior of the atomizer 100. The bottom plug 3 includes a cover 31 and a second plug 32 disposed on the cover 31, the number of the second plugs 32 being the same as the number of air holes 51.

[0065] When the bottom plug 3 is installed at the bottom of the atomizer 100, the cover 31 of the bottom plug 3 covers the outer surface of the base 5, and at the same time, each second plug 32 is inserted into each air hole 51, thereby forming a multi-hole synchronous sealing structure. In this way, the bottom of the atomizer 100 is covered and protected, and the air holes 51 on the base 5 of the atomizer 100 are sealed, improving the sealing effect and effectively preventing leakage from the bottom of the atomizer 100.

[0066] The second plug 32 on the bottom plug 3 engages with at least two air holes 51 on the base 5 of the atomizer 100, facilitating the positioning of the bottom plug 3's installation orientation and effectively improving operational efficiency. The cap 31 structure on the bottom plug 3 not only increases the coverage area of ​​the atomizer 100's bottom but also allows for convenient user operation of the cap 31 when removing the bottom plug 3, enabling the second plug 32 to be simultaneously separated from each air hole 51, thereby improving the ease of removing the bottom plug 3.

[0067] Please refer to the following: Figure 13 and Figure 14 This application also provides an electronic atomizing device, including a body 200 of the electronic atomizing device, a power supply component 8, and the atomizer 100 provided in the above-mentioned embodiment of this application. The atomizer 100 can be used as a replacement part and can be detachably connected to the body 200.

[0068] When the atomizer 100 is installed on the main body 200, the extension rod 12 of the airway plug 1 and the bottom plug 3 are removed from the atomizer 100. On the one hand, this allows the output airway 102 to be opened, enabling the aerosol generated by the atomizer coil 7 to be output from the output airway 102 and the mouthpiece 6. On the other hand, it exposes the bottom structure of the atomizer 100 for electrical connection and airway communication with the main body 200.

[0069] The power supply component 8 is housed within the main body 200, and includes a circuit board 81 and a battery 82 that provides power to the atomizer 100. Figure 16 As shown, the atomizing core 7 in the atomizer 100 includes at least a heating element 71, which has electrodes. When the atomizer 100 is mounted on the main body 200, the electrodes on the heating element 71 can be electrically connected to the circuit board 81.

[0070] In this way, the atomizer 100 can be used as a replacement part. When the atomizing liquid in the atomizer 100 is exhausted, the atomizer 100 can be removed from the main body 200 and replaced with a new atomizer 100, effectively achieving rapid battery life; or, a new atomizer 100 can be replaced to change the flavor, thereby improving the user experience.

[0071] Instructions for use of the atomizer 100 provided in this application embodiment: During the assembly stage of the atomizer 100, all parts except the mouthpiece 6 and the liquid filling plug 2 are first assembled together, such as... Figure 15 As shown, an airway plug 1 is provided at the top of the atomizer 100, and a bottom plug 3 is installed at the bottom of the atomizer 100, so that both ends of the atomizing core 7 in the atomizer 100 are sealed respectively, so that the atomizer 100 is in a ready-to-fill state. There is air in the internal cavity of the atomizing core 7. When the atomizing liquid is injected, the atomizing liquid will wet the liquid guiding parts (such as liquid guiding cotton or porous ceramic) in the atomizing core 7 under the guiding structure. However, under the action of the surface tension of the liquid and the air pressure in the internal cavity of the atomizing core 7, the atomizing liquid will not continue to flow into the cavity of the atomizing core 7, that is, leakage is prevented.

[0072] like Figure 16 As shown, after filling, insert the filling plug 2, then press the mouthpiece 6 closed, so that the locking groove 62 on the surrounding part 61 of the mouthpiece 6 engages with the locking rib 42 on the outer periphery of the upper shell 4, effectively preventing it from being pried open by external force in normal use. When the atomizer 100 reaches the user, the extension rod 12 of the airway plug 1 can be pulled off by hand to break it from the fixing sleeve 11, allowing the extension rod 12 to be pulled out for use. Since the atomizing core 7 has been pre-soaked, it can be used immediately without waiting, effectively avoiding the risk of dry burning during first use, ensuring consistent atomization effect, and improving the user experience.

[0073] It should be noted that the atomizer 100 in this embodiment of the application can preferably adopt a liquid injection structure with two liquid injection holes 101 to prevent the pressure during liquid injection from forcibly squeezing the atomized liquid into the inner cavity of the atomizing core 7.

[0074] Regarding the liquid filling method of atomizer 100, such as Figure 17 As shown, when performing single-needle injection, the air inside the nebulizer 100 can be quickly vented through the injection port 101 on the other side.

[0075] like Figure 18 As shown, when performing dual-needle injection, the air in the atomizer 100 can be quickly vented through the gap between the two injection holes 101 and the area around the fine needle.

[0076] In this way, pressure is released during the liquid filling process of the atomizer 100, thereby preventing the liquid filling pressure from forcibly squeezing the atomizing liquid into the inner cavity of the atomizing core 7 and effectively avoiding leakage.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
