Description

The disclosure relates to the field of electronic cigarettes, and more particularly, to an electronic cigarette comprising a replaceable e-liquid cartridge.
A conventional electronic cigarette typically includes a cartridge and a battery body, which can be assembled as a unit or connected together with magnets for easy detachment. The cartridge is used to store e-liquid and generate smoke through heating, while the battery body supplies power. The cartridge contains a chamber for storing e-liquid. However, the capacity of the chamber is restricted, causing the cartridge to have a finite operational duration. Once the e-liquid is used up, the cartridge needs to be replaced and cannot be recycled, resulting in higher costs and affecting the overall user satisfaction.
In addition, certain cartridges come with e-liquid injection holes. Once the e-liquid inside the cartridge is used up, more e-liquid can be injected through these e-liquid injection holes for the cartridge to be reused. However, the e-liquid injection holes are not tightly sealed, leading to issues with e-liquid leakage. Moreover, carrying extra e-liquid is inconvenient. During the e-liquid injection process through the e-liquid injection holes, external leakage can contaminate the cartridge, resulting in an unsatisfied user experience. When exposed to surrounding air during the e-liquid injection, the e-liquid can undergo oxidation and deterioration.

Additionally, the term "and/or" used in this disclosure encompasses any one or all possible combinations of the listed items.
Referring toFIGS. 1 - 12, the disclosure provides an electronic cigarette comprising a replaceable e-liquid cartridge. The electronic cigarette comprises anatomizing body 10 and ane-liquid cartridge 20. The atomizingbody 10 comprises anatomizing core 16 and ane-liquid chamber 51. Theatomizing core 16 is disposed in theatomizing body 10 to absorb and heat the e-liquid for vaporization. Thee-liquid chamber 51 is disposed in theatomizing body 10. Thee-liquid cartridge 20 is detachably connected to theatomizing body 10 to supply the e-liquid to thee-liquid chamber 51. Thee-liquid cartridge 20, functioning as a storage unit, often referred to as a reservoir or container, stores the e-liquid for the electronic cigarette. The e-liquid is commonly utilized as an alternative to conventional tobacco products and optionally comprises flavoring agents or additives to enhance the taste. By substituting differente-liquid cartridges 20, the electronic cigarette provides a range of flavors and tastes, tailoring to consumer choices. The electronic cigarette also solves the problems linked to conventional refillable electronic cigarettes, where preparing e-liquid containers and using specialized tools for replenishment becomes a cumbersome task. This convenient becomes pronounced when carrying these items while traveling. Moreover, the refilling process could lead to air entering the e-liquid container, thereby contaminating the e-liquid and impacting its taste, and resulting in health concerns due to the introduction of unfamiliar substances.
Specifically, the shape of thee-liquid cartridge 20 is not rigidly defined, as long as it fulfills the criteria of being detachable and ensuring a secure seal. In preferred embodiments of this disclosure, thee-liquid cartridge 20 is in the shape of a cylinder. When contrasted with e-liquid cartridges of other shapes, a cylindricale-liquid cartridge 20 of the equivalent dimensions can accommodate more liquid due to its larger internal space and storage capacity. This configuration promotes convenience in storage and usage. Furthermore, the manufacturing and assembly process of cylindrical e-liquid cartridges are simpler in comparison to other shapes, thereby enhancing production efficiency and reducing costs.
Referring toFIGS. 1 - 12, the atomizingbody 10 further comprises afirst shell 11 and abase 14. One end of thefirst shell 11 comprises amouthpiece 111 for inhalation, and thebase 14 is disposed at the other end of thefirst shell 11. Thee-liquid cartridge 20 is detachably connected to thebase 14. Specifically, thee-liquid chamber 51 is defined by thefirst shell 11 and thebase 14, so as to surround theatomizing core 16; thee-liquid cartridge 20 is connected to the base 14 to establish a connection that allows communication between thee-liquid cartridge 20 and thee-liquid chamber 51, making refilling thee-liquid chamber 51 easier.
Further, themouthpiece 111 functions as a passage for users to inhale the vapor; the mouthpiece comprises asmoking opening 53 connected to theatomizing core 16; the vapor produced by heating the e-liquid in theatomizing core 16 is released through thesmoking opening 53 and enters the user's mouth.
Notably, thebase 14 is detachably connected to thee-liquid cartridge 20 in a plurality of manners, comprising threaded connections, magnetic connections, snap-fit connections, or a combination thereof. In preferred embodiments of the disclosure, thee-liquid cartridge 20 is threaded onto thebase 14. This threaded connection endures tension and vibration, mitigating the risk of loosening due to external forces and preventing e-liquid leakage.
In some embodiments, as shown inFIG. 4, thee-liquid cartridge 20 comprises an exposed end; thebase 14 comprises a first through-hole 141 into which the exposed end of thee-liquid cartridge 20 is inserted, so that the liquid-cartridge is fixedly connected to the base. To prevent e-liquid leakage during the connection of thee-liquid cartridge 20 with thebase 14, as shown inFIG. 2, the base 14 further comprises aprotrusion 54 that is in the shape of a hollow cylinder, extending outward. Theprotrusion 54, which can be part of thebase 14, is connected to the first through-hole 141. Theprotrusion 54 is used to firmly secure thee-liquid cartridge 20, ensuring stability and enhancing sealing by maximizing contact. In some embodiments, theprotrusion 54 comprises an internal threading that threads into thee-liquid cartridge 20, preventing the e-liquid leakage. In some embodiments, the outer circumference of theprotrusion 54 comprises external threading, allowing thee-liquid cartridge 20 to be threaded onto theprotrusion 54.
In some embodiments, as shown inFIG. 5, instead of utilizing theprotrusion 54, a threadedconnector 17 is disposed within the first through-hole 141. The threadedconnector 17 is hollow. Thee-liquid cartridge 20 is threaded onto the base 14 through the threadedconnector 17. The threadedconnector 17 is disposed on a wall surrounding the first through-hole 141, achieving a snug fit with the base 14 through an interference fit. The threadedconnector 17 comprises metal or plastic, preferably metal. Metal threaded connectors outperform plastic threadedconnectors 17 in strength, durability, and resistance to chemicals. Additionally, the metal threaded connectors withstand higher pressure and tension, resulting in a longer lifespan. With prolonged use, the metal threaded connectors maintain sealing performance by avoiding dissolution or deformation, thereby ensuring a high-quality sealed connection.
In some embodiments, as shown inFIG. 4, the atomizingbody 10 further comprises ane-liquid guide portion 52 through which thee-liquid cartridge 20 is connected to thee-liquid chamber 51. Thee-liquid guide portion 52 comprises a sealingmember 13 functioning as a division between thee-liquid cartridge 20 and thee-liquid chamber 51. The sealingmember 13 comprises a drivingassembly 12 that is activated to induce the motion of the sealingmember 13, thereby opening or closing thee-liquid guide portion 52. The sealingmember 13 is in the shape of a sheet or a block, as long as it ensures an effective seal within thee-liquid guide portion 52. The sealingmember 13 comprises high-density elastic colloids, plastic, or metal. The term "elastic colloids", as used herein, refers to materials that deform under an external force and promptly return to their original shape once the external force is removed. This property enhances the sealing effectiveness of the sealingmember 13, preventing the e-liquid from flowing freely between the e-liquid cartridge and the e-liquid chamber when thee-liquid guide portion 52 is closed. The elastic colloids comprise natural rubber, synthetic rubber, polypropylene, and polyethylene. Given that the sealingmember 13 remains in extended contact with the e-liquid, prioritizing product safety, as well as elasticity, sealing, and cost-effectiveness, preferably, the sealingmember 13 comprises food-grade rubber. The sealingmember 13 is disposed near the first through-hole 141. Thee-liquid guide portion 52 is a passage used to connect the e-liquid cartridge and the e-liquid chamber. The term "passage" comprises both an inlet and an outlet. The passage is cylindrical, conical, frustoconical, or curved, providing a space for fluid flow.
In some embodiments, as shown inFIGS. 3,8,11, and12, the drivingassembly 12 comprises a drivingmember 121 that is activated to induce the motion of the sealingmember 13. At least a part of the drivingmember 121 is exposed on thefirst shell 11, allowing users to manually manipulate the sealing member to regulate the opening and closing of thee-liquid guide portion 52, without the need to open thefirst shell 11. Specifically, the drivingmember 121 comprises a hand-push section 1211 and apush rod 1212. Thepush rod 1212 is connected between the hand-push section 1211 and the sealingmember 13. The hand-push section 1211 is exposed on the outside of thefirst shell 11. The hand-push section 1211 is operated by manual pressing (as shown inFIGS. 3 and8), or by sliding (as shown inFIGS. 11-12).
Specifically, in some embodiments, as shown inFIGS. 3,4,7, and8, the hand-push section 1211 comprises a press-type cover. Specifically, the press-type cover comprises amain body 1211a and asidewall 1211b protruding along the edge of themain body 1211a. Thefirst shell 11 further comprises a recess inside, with aprotruding element 112 formed within the recess. Anannular groove 113 is formed between the outer edge of the recess and the protrudingelement 112. A portion of thesidewall 1211b is slidable into theannular groove 113. Upon pressing, thesidewall 1211b moves longitudinally along theannular groove 113, applying force through the pressing action.
Further, as shown inFIG. 7, the press-type cover needs to be rotated to a predefined position to active the pressing mechanism and thereby activate the movement of the sealingmember 13. This design prevents accidental operations, particularly preventing unintended use by children. The inner side of thesidewall 1211b comprises at least two strip-like blocks 1211c protruding along the circumference of thesidewall 1211b. One end of the at least two strip-like blocks 1211c protrudes in the axial direction of thesidewall 1211b and away from themain body 1211a, forming a limited-stop protrusion 1211d. Agap 1211e is formed between every two adjacent strip-like blocks 1211c. The number of the at least two strip-like blocks 1211c is determined as needed, evenly distributed. The peripheral wall of the protrudingelement 112 comprises at least oneridge 1121 used to align with the corresponding gap. The at least oneridge 1121 is slidable into the corresponding gap. When sliding toward one end of the at least two strip-like blocks 1211c, the at least oneridge 1121 is stopped by the corresponding limited-stop protrusion 1211d. Similarly, when sliding toward the other end of the at least two strip-like blocks 1211c, the at least oneridge 1121 is stopped by the adjacent limited-stop protrusions to align with thecorresponding gap 1211e. Notably, the spacing between every twoadjacent gaps 1211e is greater than or equal to the dimension of the at least oneridge 1121. When the press-type cover is rotated to a predefined position, the at least oneridge 1121 aligns with thecorresponding gap 1211e. In this configuration, the at least oneridge 1121 is movable along thecorresponding gap 1211e, allowing the press-type cover to be pressed down, thereby achieving the dual action of rotation and pressing. When the at least oneridge 1121 is not aligned with thecorresponding gap 1211e, it comes into contact with the at least two strip-like blocks 1211c, preventing the press-type cover from being pressed down. Typically, the end of the at least oneridge 1121, facing thecorresponding gap 1211e, is curved, facilitating alignment and guiding.
In some embodiments, as shown inFIGS. 3,4,7, and8, the drivingassembly 12 further comprises anelastic member 122 used to reset the sealingmember 13. The term "resetting", as used herein, refers to the automatic return of the sealingmember 13 to the closed position of thee-liquid guide portion 52 through the action of theelastic member 122. One end of theelastic member 122 is secured to any component on the atomizing body. The other end of theelastic member 122 is connected to the hand-push section 1211 or the sealingmember 13. Theelastic element 122 comprises a spring, an elastic strip, or an elastic colloid, preferably, a spiral-shaped spring.
In some embodiments, as shown inFIGS. 3,4,8,11, and12, thefirst shell 11 further comprises asmoke guide tube 114 communicating with thesmoking opening 53. Theatomizing core 16 is disposed within thefirst shell 11 to heat and atomize the e-liquid. Thee-liquid chamber 51 surrounds theatomizing core 16. Thebase 14 is disposed at one end of thefirst shell 11, away from thesmoking opening 53. Theatomizing core 16 comprises anatomizing tube 161 and aheating core 162 disposed inside theatomizing tube 161. Theatomizing tube 161 comprises ane-liquid inlet 163 disposed corresponding to thee-liquid chamber 51 and theheating core 162. Theatomizing tube 161 is connected between thesmoke guide tube 114 and thebase 14. Specifically, theatomizing tube 161 is connected between thesmoke guide tube 114 and the base 14 through interference fits. Theatomizing tube 161 comprises an airflow passage. Theatomizing tube 161 functions to isolate the airflow passage from thee-liquid chamber 51. The e-liquid flows into the heating core via thee-liquid inlet 163 and is heated by the heating core to produce vapor. The vapor is then carried through theatomizing tube 161 by the airflow. The heating core comprises an e-liquid guide body and a heating element. The e-liquid guide body comprises a ceramic body or an absorbent cotton, and the heating element comprises conductive metal. For example, the heating core comprises a hollow ceramic body and a heating wire; the hollow ceramic body is used to absorb the e-liquid, and the heating wire is embedded in the inner wall of the ceramic body. Another example is that the heating core comprises an absorbent cotton and a heating wire wound around the absorbent cotton or embedded within the absorbent cotton. In some embodiments, the atomizing core lacks the atomizing tube, where the smoke guide tube extends axially into the e-liquid chamber and is connected to the top part of the heating core, and typically, the absorbent cotton and the heating element constitute the heating core.
In some embodiments, as shown inFIGS. 3,4,8,11, and12, to prevent any leakage of e-liquid and the infiltration of air into an atomizer, ensuring the optimal functioning of the electronic cigarette, the atomizingbody 10 further comprises a sealingplug 15 disposed within thefirst shell 11 to seal thee-liquid chamber 51, thereby preventing the e-liquid leakage. The sealingplug 15 is disposed on one side of thebase 14 and within the first shell. Theatomizing tube 161 is connected between the sealingplug 15 and thesmoke guide tube 114.
In some embodiments, as shown inFIG. 4, the sealingplug 15 comprises a second through-hole 151. The first through-hole is connected to the second through-hole to constitute thee-liquid guide portion 52. The sealingmember 13 abuts against on the side of the sealingplug 15 that is directed towards the base 14 to seal the second through-hole 151. Apush rod 1212 extends from thefirst shell 11 toward the sealingmember 13, and is connected between the sealingmember 13 and the hand-push section 1211.
In some embodiments, the base 14 further comprises anair inlet 142 communicating with theatomizing tube 161. The electronic cigarette further comprises a firstconductive electrode 164 disposed on the outside of thebase 14.

The first through-hole 141 is connected to the second through-hole 151 to constitute thee-liquid guide portion 52. The threadedconnector 17 is disposed around the first through-hole 141 and connected to thee-liquid cartridge 20. The base 14 further comprises a protrusion that is hollow and extends outward alongside the first through-hole 141. The threadedconnector 17 is disposed within theprotrusion 54. Thee-liquid cartridge 20 is threaded onto the threadedconnector 17 to direct the e-liquid through thee-liquid guide portion 52, thee-liquid chamber 51, and into the heating chamber. To prevent the e-liquid vapor within thee-liquid guide portion 52 from returning to thee-liquid cartridge 20 without entering thee-liquid chamber 51, the sealingmember 13 is disposed at the first through-hole 141. Specifically, the sealingmember 13 is disposed on the side of the base 14 that is oriented towards thee-liquid cartridge 20 and securely fits with the base 14 using an interference fit.

To control the opening and closing of the sealingmember 13, the drivingmember 121 is activated to induce the motion of the sealingmember 13. The hand-push section 1211 comprises a press-type cover disposed on the outside of thefirst shell 11. Thepush rod 1212 is disposed between the sealingmember 13 and the hand-push section 1211. The press-type cover, thepush rod 1212, and the sealingmember 13 are arranged in a vertical manner. The press-type cover comprises amain body 1211a and asidewall 1211b protruding along the edge of themain body 1211a. Thefirst shell 11 further comprises a recess inside, with aprotruding element 112 formed within the recess. Anannular groove 113 is formed between the outer edge of the recess and the protruding element. A portion of thesidewall 1211b is slidable into theannular groove 113. Positioning is achieved by inserting thesidewall 1211b into theannular groove 113. The press-type cover can be pressed repeatedly. The drivingassembly 12 further comprises anelastic member 122 used to reset the sealingmember 13. Theelastic member 122 comprises a spring. One end of the spring abuts against the press-type cover, and the other end of the spring abuts within theannular groove 113. The spring functions to absorb and store external forces by utilizing its elastic deformation energy. Once the external forces diminish, the spring returns to its initial form and releases the stored energy, resulting in the press-type cover bouncing back from theannular groove 113. This mechanism facilitates the capability for repeated pressing.

Example 2

Example 2 shares the same characteristics as Example 1, except for specific variations shown inFIGS. 7-8: the hand-push section comprises a press-type cover that needs to be rotated to a predefined position to active the pressing mechanism; and the structure of thefirst shell 11 is adjusted to accommodate the drivingmember 121.

The inner side of thesidewall 1211b comprises four strip-like blocks 1211c protruding along the circumference of thesidewall 1211b and evenly distributed around thepush rod 1212 at 90-degree intervals. Each end of the four strip-like blocks 1211c protrudes in the axial direction of thesidewall 1211b and away from themain body 1211a, forming a limited-stop protrusion 1211d. Agap 1211e is formed between every two adjacent strip-like blocks 1211c. The peripheral wall of the protrudingelement 112 comprises at least oneridge 1121 used to align with the corresponding gap. The at least oneridge 1121 fits thecorresponding gap 1211e in width. The at least oneridge 1121 is slidable into the corresponding gap. When sliding toward the one end of each of the four strip-like blocks 1211c, the at least oneridge 1121 is stopped by the adjacent limited-stop protrusions to align with thecorresponding gap 1211e. In this configuration, at least oneridge 1121 is movable along thecorresponding gap 1211e, allowing the press-type cover to be pressed down. Unlike Example 1, where direct pressing is used, Example 2 achieves a positioning function through rotation and pressing, effectively preventing inadvertent triggering due to collisions during movement.

Notably, the protrudingelement 112 further comprises a circular recess (not shown in the figures); one end of the elastic member 122 (e.g., a spring) abuts against the main body of the press-type cover, and the other end of theelastic member 122 is disposed within the circular recess.

Understandably, the angle of rotation and positioning is directly related to the number of the strip-like blocks. When two strip-like blocks 1211c are present, a 180-degree rotation achieves pressing, and when three strip-like blocks 1211c are present, a 120-degree rotation achieves pressing.

The other structures of the electronic cigarette in Example 2 are similar to those in Example 1 and are not described herein.

Example 3

Example 3 shares the same characteristics as Examples 1 and 2, except for specific variations shown inFIGS. 11-12: the drivingassembly 12 is laterally disposed within thee-liquid guide portion 52, and the sealingmember 13 is disposed inside the atomizingbody 10.

The drivingmember 121 comprises a hand-push section 1211 and apush rod 1212. The hand-push section 1211 comprises a sliding button. The first shell comprises a guide groove disposed corresponding to the sliding button. The main body of the hand-push section 1211 is disposed on the outside of thefirst shell 11 and comprises a connecting part rigidly connected to thepush rod 1212. The sealingmember 13 is disposed inside thefirst shell 11 and connected to thepush rod 1212. The sealingmember 13 and thepush rod 1212 are arranged laterally. One end of theelastic member 122 abuts against the sealingmember 13, and the other end of theelastic member 122 abuts against the inner wall of thefirst shell 11. When the sliding button is pushed by the user along the guide groove, thepush rod 1212 moves laterally. Once the external force is released, the sealingmember 13 rebounds to its position of sealing thee-liquid guide portion 52 under the action of theelastic member 122. InFIG. 11, the sealingmember 13 is shown not sealing thee-liquid guide portion 52, and inFIG. 12, the sealingmember 13 is shown sealing thee-liquid guide portion 52.

The other structures of the electronic cigarette in Example 3 are similar to those in Examples 1-2 and are not described herein.
