Description

CROSS-REFERENCE TO RELATED APPLICATIONS

Pursuant to 35 U.S.C. § 119 and the Paris Convention Treaty, this application claims foreign priority to Chinese Patent Application No. 202310674998.2 filed Jun. 7, 2023, and to Chinese Patent Application No. 202321445081.7 filed Jun. 7, 2023. The contents of all of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference.

BACKGROUND

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 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.

DETAILED DESCRIPTION

To further illustrate the disclosure, embodiments detailing an electronic cigarette comprising a replaceable e-liquid cartridge are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

In this disclosure, unless otherwise explicitly specified and limited, terms like “connection” should be understood in a broad sense. For example, they could refer to direct connection or indirect connection through an intermediary medium. It could encompass either an internal linkage between two components or an interactive relationship between the components, unless otherwise specifically restricted. To those skilled in the art, the specific meanings of the aforementioned terms in this disclosure can be understood based on the context and specifics.

In the disclosure, the term “fluid connection”, as used herein, implies that fluid (including liquid and/or gas) can flow from one component to another. Moreover, the term “connection” between two components can denote direct alignment, such as when at least part of two holes align, or it can involve an intermediary medium.

Throughout the disclosure, the terms used in descriptions of various examples serve the purpose of illustrating specific instances rather than imposing limitations. Unless context clearly indicates otherwise, if the quantity of an element is not explicitly stated, it could be singular or plural. Additionally, the term “and/or” used in this disclosure encompasses any one or all possible combinations of the listed items.

Referring to FIGS. 1-12, the disclosure provides an electronic cigarette comprising a replaceable e-liquid cartridge. The electronic cigarette comprises an atomizing body 10 and an e-liquid cartridge 20. The atomizing body 10 comprises an atomizing core 16 and an e-liquid chamber 51. The atomizing core 16 is disposed in the atomizing body 10 to absorb and heat the e-liquid for vaporization. The e-liquid chamber 51 is disposed in the atomizing body 10. The e-liquid cartridge 20 is detachably connected to the atomizing body 10 to supply the e-liquid to the e-liquid chamber 51. The e-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 different e-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 the e-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, the e-liquid cartridge 20 is in the shape of a cylinder. When contrasted with e-liquid cartridges of other shapes, a cylindrical e-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 to FIGS. 1-12, the atomizing body 10 further comprises a first shell 11 and a base 14. One end of the first shell 11 comprises a mouthpiece 111 for inhalation, and the base 14 is disposed at the other end of the first shell 11. The e-liquid cartridge 20 is detachably connected to the base 14. Specifically, the e-liquid chamber 51 is defined by the first shell 11 and the base 14, so as to surround the atomizing core 16; the e-liquid cartridge 20 is connected to the base 14 to establish a connection that allows communication between the e-liquid cartridge 20 and the e-liquid chamber 51, making refilling the e-liquid chamber 51 easier.

Further, the mouthpiece 111 functions as a passage for users to inhale the vapor; the mouthpiece comprises a smoking opening 53 connected to the atomizing core 16; the vapor produced by heating the e-liquid in the atomizing core 16 is released through the smoking opening 53 and enters the user's mouth.

Notably, the base 14 is detachably connected to the e-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, the e-liquid cartridge 20 is threaded onto the base 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 in FIG. 4, the e-liquid cartridge 20 comprises an exposed end; the base 14 comprises a first through-hole 141 into which the exposed end of the e-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 the e-liquid cartridge 20 with the base 14, as shown in FIG. 2, the base 14 further comprises a protrusion 54 that is in the shape of a hollow cylinder, extending outward. The protrusion 54, which can be part of the base 14, is connected to the first through-hole 141. The protrusion 54 is used to firmly secure the e-liquid cartridge 20, ensuring stability and enhancing sealing by maximizing contact. In some embodiments, the protrusion 54 comprises an internal threading that threads into the e-liquid cartridge 20, preventing the e-liquid leakage. In some embodiments, the outer circumference of the protrusion 54 comprises external threading, allowing the e-liquid cartridge 20 to be threaded onto the protrusion 54.

In some embodiments, as shown in FIG. 5, instead of utilizing the protrusion 54, a threaded connector 17 is disposed within the first through-hole 141. The threaded connector 17 is hollow. The e-liquid cartridge 20 is threaded onto the base 14 through the threaded connector 17. The threaded connector 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 threaded connector 17 comprises metal or plastic, preferably metal. Metal threaded connectors outperform plastic threaded connectors 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 in FIG. 4, the atomizing body 10 further comprises an e-liquid guide portion 52 through which the e-liquid cartridge 20 is connected to the e-liquid chamber 51. The e-liquid guide portion 52 comprises a sealing member 13 functioning as a division between the e-liquid cartridge 20 and the e-liquid chamber 51. The sealing member 13 comprises a driving assembly 12 that is activated to induce the motion of the sealing member 13, thereby opening or closing the e-liquid guide portion 52. The sealing member 13 is in the shape of a sheet or a block, as long as it ensures an effective seal within the e-liquid guide portion 52. The sealing member 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 sealing member 13, preventing the e-liquid from flowing freely between the e-liquid cartridge and the e-liquid chamber when the e-liquid guide portion 52 is closed. The elastic colloids comprise natural rubber, synthetic rubber, polypropylene, and polyethylene. Given that the sealing member 13 remains in extended contact with the e-liquid, prioritizing product safety, as well as elasticity, sealing, and cost-effectiveness, preferably, the sealing member 13 comprises food-grade rubber. The sealing member 13 is disposed near the first through-hole 141. The e-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 in FIGS. 3, 8, 11, and 12, the driving assembly 12 comprises a driving member 121 that is activated to induce the motion of the sealing member 13. At least a part of the driving member 121 is exposed on the first shell 11, allowing users to manually manipulate the sealing member to regulate the opening and closing of the e-liquid guide portion 52, without the need to open the first shell 11. Specifically, the driving member 121 comprises a hand-push section 1211 and a push rod 1212. The push rod 1212 is connected between the hand-push section 1211 and the sealing member 13. The hand-push section 1211 is exposed on the outside of the first shell 11. The hand-push section 1211 is operated by manual pressing (as shown in FIGS. 3 and 8), or by sliding (as shown in FIGS. 11-12).

Specifically, in some embodiments, as shown in FIGS. 3, 4, 7, and 8, the hand-push section 1211 comprises a press-type cover. Specifically, the press-type cover comprises a main body 1211a and a sidewall 1211b protruding along the edge of the main body 1211a. The first shell 11 further comprises a recess inside, with a protruding element 112 formed within the recess. An annular groove 113 is formed between the outer edge of the recess and the protruding element 112. A portion of the sidewall 1211b is slidable into the annular groove 113. Upon pressing, the sidewall 1211b moves longitudinally along the annular groove 113, applying force through the pressing action.

Further, as shown in FIG. 7, the press-type cover is rotatable to a predefined position to active the pressing mechanism and thereby activate the movement of the sealing member 13. This design prevents accidental operations, particularly preventing unintended use by children. The inner side of the sidewall 1211b comprises at least two strip-like blocks 1211c protruding along the circumference of the sidewall 1211b. One end of the at least two strip-like blocks 1211c protrudes in the axial direction of the sidewall 1211b and away from the main body 1211a, forming a limited-stop protrusion 1211d. A gap 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 protruding element 112 comprises at least one ridge 1121 used to align with the corresponding gap. The at least one ridge 1121 is slidable into the corresponding gap. When sliding toward one end of the at least two strip-like blocks 1211c, the at least one ridge 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 one ridge 1121 is stopped by the adjacent limited-stop protrusions to align with the corresponding gap 1211e. Notably, the spacing between every two adjacent gaps 1211e is greater than or equal to the dimension of the at least one ridge 1121. When the press-type cover is rotated to a predefined position, the at least one ridge 1121 aligns with the corresponding gap 1211e. In this configuration, the at least one ridge 1121 is movable along the corresponding gap 1211e, allowing the press-type cover to be pressed down, thereby achieving the dual action of rotation and pressing. When the at least one ridge 1121 is not aligned with the corresponding 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 one ridge 1121, facing the corresponding gap 1211e, is curved, facilitating alignment and guiding.

In some embodiments, as shown in FIGS. 3, 4, 7, and 8, the driving assembly 12 further comprises an elastic member 122 used to reset the sealing member 13. The term “resetting”, as used herein, refers to the automatic return of the sealing member 13 to the closed position of the e-liquid guide portion 52 through the action of the elastic member 122. One end of the elastic member 122 is secured to any component on the atomizing body. The other end of the elastic member 122 is connected to the hand-push section 1211 or the sealing member 13. The elastic element 122 comprises a spring, an elastic strip, or an elastic colloid, preferably, a spiral-shaped spring.

In some embodiments, as shown in FIGS. 3, 4, 8, 11, and 12, the first shell 11 further comprises a smoke guide tube 114 communicating with the smoking opening 53. The atomizing core 16 is disposed within the first shell 11 to heat and atomize the e-liquid. The e-liquid chamber 51 surrounds the atomizing core 16. The base 14 is disposed at one end of the first shell 11, away from the smoking opening 53. The atomizing core 16 comprises an atomizing tube 161 and a heating core 162 disposed inside the atomizing tube 161. The atomizing tube 161 comprises an e-liquid inlet 163 disposed corresponding to the e-liquid chamber 51 and the heating core 162. The atomizing tube 161 is connected between the smoke guide tube 114 and the base 14. Specifically, the atomizing tube 161 is connected between the smoke guide tube 114 and the base 14 through interference fits. The atomizing tube 161 comprises an airflow passage. The atomizing tube 161 functions to isolate the airflow passage from the e-liquid chamber 51. The e-liquid flows into the heating core via the e-liquid inlet 163 and is heated by the heating core to produce vapor. The vapor is then carried through the atomizing 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 in FIGS. 3, 4, 8, 11, and 12, to prevent any leakage of e-liquid and the infiltration of air into an atomizer, ensuring the optimal functioning of the electronic cigarette, the atomizing body 10 further comprises a sealing plug 15 disposed within the first shell 11 to seal the e-liquid chamber 51, thereby preventing the e-liquid leakage. The sealing plug 15 is disposed on one side of the base 14 and within the first shell. The atomizing tube 161 is connected between the sealing plug 15 and the smoke guide tube 114.

In some embodiments, as shown in FIG. 4, the sealing plug 15 comprises a second through-hole 151. The first through-hole communicates with the second through-hole to constitute the e-liquid guide portion 52. The sealing member 13 abuts against on the side of the sealing plug 15 that is directed towards the base 14 to seal the second through-hole 151. A push rod 1212 extends from the first shell 11 toward the sealing member 13, and is connected between the sealing member 13 and the hand-push section 1211.

In some embodiments, the base 14 further comprises an air inlet 142 communicating with the atomizing tube 161. The electronic cigarette further comprises a first conductive electrode 164 disposed on the outside of the base 14. In some embodiments, as shown in FIG. 5, the atomizing tube 161 comprises one end sealed and extending from the base 14; the peripheral wall of the sealed end comprises an air inlet 142; at least a portion of the air inlet 142 is exposed on the outside of the base 14; and the first conductive electrode 164 is disposed on the sealed end of the atomizing tube 161.

The sealing plug 15 is disposed on the base 14 and within the first shell to secure the atomizing core 16 in the e-liquid chamber 51, thereby preventing the e-liquid leakage. The base 14 comprises a first through-hole 141, and the sealing plug 15 comprises a second through-hole 151. The first through-hole 141 communicates with the second through-hole 151 to constitute the e-liquid guide portion 52. The threaded connector 17 is disposed around the first through-hole 141 and connected to the e-liquid cartridge 20. The base 14 further comprises a protrusion that is hollow and extends outward alongside the first through-hole 141. The threaded connector 17 is disposed within the protrusion 54. The e-liquid cartridge 20 is threaded onto the threaded connector 17 to direct the e-liquid through the e-liquid guide portion 52, the e-liquid chamber 51, and into the heating chamber. To prevent the e-liquid vapor within the e-liquid guide portion 52 from returning to the e-liquid cartridge 20 without entering the e-liquid chamber 51, the sealing member 13 is disposed at the first through-hole 141. Specifically, the sealing member 13 is disposed on the side of the base 14 that is oriented towards the e-liquid cartridge 20 and securely fits with the base 14 using an interference fit.

To control the opening and closing of the sealing member 13, the driving member 121 is activated to induce the motion of the sealing member 13. The hand-push section 1211 comprises a press-type cover disposed on the outside of the first shell 11. The push rod 1212 is disposed between the sealing member 13 and the hand-push section 1211. The press-type cover, the push rod 1212, and the sealing member 13 are arranged in a vertical manner. The press-type cover comprises a main body 1211a and a sidewall 1211b protruding along the edge of the main body 1211a. The first shell 11 further comprises a recess inside, with a protruding element 112 formed within the recess. An annular groove 113 is formed between the outer edge of the recess and the protruding element. A portion of the sidewall 1211b is slidable into the annular groove 113. Positioning is achieved by inserting the sidewall 1211b into the annular groove 113. The press-type cover can be pressed repeatedly. The driving assembly 12 further comprises an elastic member 122 used to reset the sealing member 13. The elastic 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 the annular 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 the annular 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 in FIGS. 7-8: the hand-push section comprises a press-type cover that is rotatable to a predefined position to active the pressing mechanism; and the structure of the first shell 11 is adjusted to accommodate the driving member 121.

The inner side of the sidewall 1211b comprises four strip-like blocks 1211c protruding along the circumference of the sidewall 1211b and evenly distributed around the push rod 1212 at 90-degree intervals. Each end of the four strip-like blocks 1211c protrudes in the axial direction of the sidewall 1211b and away from the main body 1211a, forming a limited-stop protrusion 1211d. A gap 1211e is formed between every two adjacent strip-like blocks 1211c. The peripheral wall of the protruding element 112 comprises at least one ridge 1121 used to align with the corresponding gap. The at least one ridge 1121 fits the corresponding gap 1211e in width. The at least one ridge 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 one ridge 1121 is stopped by the adjacent limited-stop protrusions to align with the corresponding gap 1211e. In this configuration, at least one ridge 1121 is movable along the corresponding 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 protruding element 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 the elastic 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 in FIGS. 11-12: the driving assembly 12 is laterally disposed within the e-liquid guide portion 52, and the sealing member 13 is disposed inside the atomizing body 10.

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

Referring to FIGS. 5 and 6, the atomizing body 10 is detachably disposed within the third chamber 313. One end of the battery cell 32, oriented towards the third chamber 313, comprises a second conductive electrode 321. When replacing the e-liquid cartridge, the atomizing body 10 is disconnected from the third chamber 313. The e-liquid cartridge 20 is unscrewed from the threaded connector 17 and replaced with a new e-liquid cartridge. Then, the atomizing body 10 is put back into position within the third chamber 313.

Example 5

Referring to FIGS. 9 and 10, the first shell 11 and the second shell 31 are fixedly connected or integrally formed. In some embodiments, one end of the first chamber 311 is disposed away from the atomizing body 10 and comprises a first opening 3111. The electronic cigarette further comprises a sealing cap 3112 disposed on the first opening 3111 and used to open or close the first chamber 311. One end of the e-liquid cartridge 20 is disposed towards the first opening 3111 and comprises a knob switch 21 used for detaching and attaching the e-liquid cartridge 20 from the first opening 3111. The knob switch 21 is in the shape of the letter “I” or “X”. The features facilitate the users in gripping the knob switch 21 firmly with their fingers at the bottom part of the e-liquid cartridge 20 and rotating the knob switch 21 to detach the atomizing body 10 from the e-liquid cartridge 20. To replace the e-liquid cartridge 20, the users open the sealing cap 3112, rotate the bottom part of the e-liquid cartridge 20, and detach the e-liquid cartridge 20 from the second opening 3113. This design ensures structural integrity while the convenience of an integrated shell design aids cost-effective manufacturing.
