Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a large-capacity insert-type atomizer structure. Background Technology

[0002] An electronic cigarette is an electronic device that simulates the function of a traditional cigarette. It heats e-liquid containing ingredients such as nicotine, propylene glycol, glycerin, and flavorings to produce vapor for the user to inhale, providing a smoking-like experience. Electronic cigarettes are typically battery-powered and come with replaceable cartridges or e-liquid containers, as well as a heating element. The battery-powered heating coil evaporates the e-liquid at a specific temperature, creating a fine mist for the user to inhale. The design of electronic cigarettes aims to mimic the smoking experience of traditional cigarettes while reducing the harmful substances produced by combustion.

[0003] Currently, e-cigarette products on the market are mainly divided into two categories: small-capacity refillable e-cigarettes and large-capacity e-cigarettes with e-liquid reservoirs. While small-capacity refillable e-cigarettes are portable, their e-liquid capacity is typically between 1-2 ml, resulting in short usage time and the need for frequent cartridge replacements, which is inconvenient for users. On the other hand, large-capacity e-cigarettes with e-liquid reservoirs offer more e-liquid capacity, but their structure is relatively complex, leading to uneven e-liquid penetration, a tendency to leak, and poor flavor consistency. Utility Model Content

[0004] The main purpose of this utility model is to propose a large-capacity insert-type atomizer structure, which aims to provide a large-capacity insert-type atomizer structure that can ensure uniform e-liquid penetration and stable flavor without the need for frequent cartridge replacement.

[0005] To achieve the above objectives, the present invention proposes a large-capacity insert-type atomizer structure, comprising a housing and an atomizing component. The housing has an oil storage chamber, and the atomizing component is disposed in the oil storage chamber. The atomizing component includes a cover, an oil storage cotton, and an atomizing core. The cover is disposed in the oil storage chamber and forms an atomizing chamber, and the atomizing core is disposed in the atomizing chamber. The oil storage cotton covers the atomizing core. The cover has an oil passage hole connecting the oil storage chamber and the atomizing chamber. The atomizing chamber is connected to the mouthpiece at one end of the housing.

[0006] In one embodiment, the housing includes an upper shell and a base, the base is provided with a first sealing member in the circumferential direction, the first sealing member is in sealing contact with the inner circumferential wall of the upper shell, and the suction nozzle is located at the end of the upper shell away from the base;

[0007] The cover is inserted through the base and sealed against the base, with a portion of the cover structure located outside the oil storage cavity.

[0008] In one embodiment, the cover is fitted with a second sealing member, which abuts against the inner peripheral wall of the base, and the oil passage hole is located on the side of the second sealing member facing the oil storage cavity.

[0009] In one embodiment, the upper shell is provided with a snap-fit ​​groove, and the base is provided with a snap-fit ​​protrusion, the snap-fit ​​protrusion being snapped into the snap-fit ​​groove.

[0010] In one embodiment, the base has an oil filling hole on the side facing away from the suction nozzle. The oil filling hole connects the oil storage chamber to the outside and is equipped with an oil filling plug.

[0011] In one embodiment, the nozzle has an extension extending toward the atomizing chamber;

[0012] The high-capacity insert-type atomizer structure also includes a movable sleeve, which is fitted onto the cover. The movable sleeve has a first end and a second end that are close to and away from the mouthpiece. The first end is provided with an annular step, which is sealed against the cover. The inner peripheral wall of the first end is sealed against the outer peripheral wall of the extension.

[0013] In one embodiment, the second end is provided with a third seal, which abuts against a portion of the structure of the housing.

[0014] In one embodiment, the high-capacity insert atomizer structure further includes a fourth seal, which abuts against the movable sleeve, the extension, and the cover, respectively.

[0015] In one embodiment, the high-capacity insertable atomizer structure further includes a bottom cover, which is located at the end of the cover away from the mouthpiece, and the bottom cover and the cover together form the atomizing chamber.

[0016] In one embodiment, the bottom cover is provided with condensation cotton on the side facing the atomizing chamber.

[0017] This invention employs a composite structure that combines large-capacity e-liquid storage with small-capacity atomization, thus optimizing the problems of short usage time in small-capacity / large-capacity insert atomizers and uneven e-liquid penetration and unstable flavor in large-capacity insert atomizers. Specifically, the large-capacity insert atomizer structure proposed in this invention mainly includes a shell and an atomizing component. The shell has an e-liquid storage chamber for large-capacity storage, and the atomizing component extends entirely into this chamber. A cover separates the atomizing chamber within the e-liquid storage chamber. This atomizing chamber contains an atomizing coil and e-liquid storage cotton, and it is connected to the mouthpiece on the shell. The cover has an e-liquid passage hole to allow e-liquid to enter the atomizing chamber from the e-liquid storage chamber. In actual use, the e-liquid storage chamber, thanks to its large space, can store a large amount of e-liquid, which flows evenly into the atomizing chamber through the e-liquid passage hole and wets the e-liquid storage cotton. This design divides the shell into two parts, which can combine large capacity e-liquid storage with uniform atomization of e-liquid, resulting in a stable taste experience for users.

[0029] This utility model proposes a large-capacity insert-type atomizer structure 100, aiming to provide a large-capacity insert-type atomizer structure 100 that eliminates the need for frequent cartridge replacements while ensuring uniform e-liquid penetration and stable flavor. Figures 1 to 4 This is a schematic diagram of one embodiment of the large-capacity insert-type atomizer structure 100 of this utility model.

[0030] Please refer to Figures 1 to 4 This utility model proposes a large-capacity insert-type atomizer structure 100, including a housing 1 and an atomizing component 2. The housing 1 is provided with an oil storage chamber 1a, and the atomizing component 2 is disposed in the oil storage chamber 1a. The atomizing component 2 includes a cover 21, an oil storage cotton 22, and an atomizing core 23. The cover 21 is disposed in the oil storage chamber 1a and forms an atomizing chamber 2a. The atomizing core 23 is disposed in the atomizing chamber 2a, and the oil storage cotton 22 covers the atomizing core 23. The cover 21 is provided with an oil passage hole 211 connecting the oil storage chamber 1a and the atomizing chamber 2a. The atomizing chamber 2a is connected to a mouthpiece 111 at one end of the housing 1.

[0031] The technical solution of this utility model optimizes the problems of short usage time of small-capacity large-capacity insert atomizer structure 100 and uneven e-liquid penetration and unstable flavor of large-capacity insert atomizer structure 100 by adopting a composite structure that combines large-capacity oil storage and small-capacity atomization. Specifically, the large-capacity insert atomizer structure 100 proposed in this utility model mainly includes two parts: a shell 1 and an atomizing component 2. The shell 1 is provided with an oil storage chamber 1a for large-capacity oil storage. The atomizing component 2 extends entirely into the oil storage chamber 1a, and an atomizing chamber 2a is separated from the oil storage chamber 1a by a cover 21. The atomizing chamber 2a is provided with an atomizing core 23 and an oil storage cotton 22, and the atomizing chamber 2a is connected to the mouthpiece 111 on the shell 1. The cover 21 is provided with an oil passage hole 211 so that e-liquid can enter the atomizing chamber 2a from the oil storage chamber 1a. In actual use, the oil storage chamber 1a, thanks to its large space, can store a large amount of e-liquid. The e-liquid flows evenly into the atomization chamber 2a through the oil outlet 211 and wets the oil storage cotton 22. This design, by dividing the shell 1 into two parts, can achieve both large-capacity oil storage and uniform atomization of the e-liquid, resulting in a stable taste experience for the user.

[0032] It should be noted that the volume of the oil reservoir 1a can be designed according to actual needs, and this utility model does not impose any restrictions on it. For example, if the user only considers the usage time of the large-capacity insert-type atomizer structure 100, the volume of the oil reservoir 1a can be designed to be more than 15ml; if the user is more concerned about the portability of the large-capacity insert-type atomizer structure 100, the volume of the oil reservoir 1a can be designed to be around 10ml, thereby making the overall size of the large-capacity insert-type atomizer structure 100 more compact and easier to carry. In one embodiment of this utility model, the volume of the oil reservoir 1a in the large-capacity insert-type atomizer structure 100 is 10ml, and the volume of the atomizing component 2 is 2ml, thereby ensuring that the large-capacity insert-type atomizer structure 100 has a longer usage time and a more stable smoke flavor.

[0033] By designing a partitioned inner cavity for the housing 1, the atomizing space and the oil storage space are separated from each other, and the two are independent and do not affect each other. E-liquid only passes through the oil passage 211 located on the cover 21 in a measured manner, thus ensuring that there is neither too much nor too little e-liquid in the atomizing chamber 2a, which guarantees the stability of the flavor during user use. In one embodiment of this utility model, the housing 1 adopts an assembly design, which is assembled from two parts: an upper shell 11 and a base 12. It should be noted that the upper shell 11 and the base 12 can be connected by snap-fit ​​or by adhesive, and this utility model does not limit this. In one embodiment of this utility model, the upper shell 11 is provided with a snap-fit ​​groove 112, and correspondingly, the base 12 is provided with a snap-fit ​​protrusion 121. Through the snap-fit ​​cooperation of the snap-fit ​​groove 112 and the snap-fit ​​protrusion 121, the upper shell 11 and the base 12 are assembled to form the housing 1, and the upper shell 11 and the base 12 together form the oil storage chamber 1a mentioned above.

[0034] To prevent leakage of the e-liquid stored in the oil storage chamber 1a, a first sealing element 3 is provided circumferentially on the base 12. For details, please refer to further documentation. Figure 3 and Figure 4 The first sealing element 3 is in sealing contact with the inner peripheral wall of the upper shell 11. The first sealing element 3 is generally annular and has multiple annular protrusions. Each annular protrusion abuts against the inner peripheral wall of the upper shell 11 to achieve a seal and prevent e-liquid from leaking from the joint between the base 12 and the upper shell 11.

[0035] In one embodiment of this utility model, the cover 21 is disposed through the base 12 of the housing 1 and partially extends into the oil storage cavity 1a. The base 12 adopts a concave design, that is, the bottom surface of the base 12 is curved into the oil storage cavity 1a. For details, please refer to further description. Figure 4 To prevent e-liquid leakage due to gaps at the connection between the cover 21 and the base 12, a second sealing element 4 is fitted onto the end of the cover 21 near the base 12. The second sealing element 4 abuts against the outer wall of the concave portion of the base 12, thereby achieving a sealing effect. Furthermore, the base 12 has an annular snap-fit ​​portion (not shown in the figure) in its outer cavity for abutting against the cover 21. The lower surface of the annular snap-fit ​​portion abuts against the second sealing element 4, thereby achieving a double seal.

[0036] To facilitate the oil filling operation into the oil storage chamber 1a, the base 12 has an oil filling hole on the side facing away from the suction nozzle 111. The oil filling hole connects the oil storage chamber 1a to the outside. For details, please refer to further documentation. Figure 4The filling port is equipped with a filling plug 122, which is usually a small cap that can be pulled out or unscrewed. Gently pull out or unscrew the filling plug 122 to expose the filling port. Then, use the matching dropper or filling needle to draw an appropriate amount of e-liquid, insert the dropper or filling needle into the filling port, and slowly inject the e-liquid into the reservoir 1a of the large-capacity insert atomizer structure 100. After filling, carefully reinstall the filling plug 122, ensuring it is properly sealed to prevent e-liquid leakage. Finally, let the large-capacity insert atomizer structure 100 sit for a period of time to allow the e-liquid to fully penetrate the atomizer coil 23 before restarting the device for the best user experience.

[0037] To allow the e-liquid in the reservoir 1a to seep into the atomizing chamber 2a, the large-capacity insert atomizer structure 100 has a movable sleeve 5 inside. For details, please refer to further documentation. Figures 3 to 4 The movable sleeve 5 is fitted onto the cover 21. By pushing the movable sleeve 5 upward, e-liquid can seep from the oil storage chamber 1a into the atomizing chamber 2a. The movable sleeve 5 has a first end and a second end, one near the mouthpiece 111 and the other far from the mouthpiece 111. The first end has an annular step 52, which seals against the cover 21. The inner peripheral wall of the first end seals against the outer peripheral wall of the extension 113. The second end has a third seal 51, which abuts against a portion of the structure of the housing 1. The large-capacity insert-type atomizer structure 100 also includes a fourth seal 6, which abuts against the movable sleeve 5, the extension 113, and the cover 21.

[0038] In one embodiment of this utility model, the large-capacity insert-type atomizer structure 100 further includes a bottom cover 7. For details, please refer to further details. Figure 4 The bottom cover 7 is located at the end of the cover 21 away from the mouthpiece 111 and together with the cover 21 forms the atomizing chamber 2a. A condensation cotton 71 is provided on the side of the bottom cover 7 facing the atomizing chamber 2a. The condensation cotton 71 in the large-capacity insert-type atomizer structure 100 is mainly used to absorb and store the condensate generated during atomization, preventing this condensate from flowing back into the airway, thus avoiding affecting the taste and atomization effect. It is usually placed at the airway inlet or the bottom of the e-liquid reservoir of the atomizer. By absorbing condensate, it keeps the airway dry and clean, reducing unpleasant odors and moisture in the inhaled taste, and improving the overall user experience.

[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
