Description

Technology Field

[0001] This specification relates to a drip tip for preventing liquid splashing. Specifically, it relates to a drip tip for preventing liquid splashing that can effectively block fine liquid from entering the user's mouth when using an electronic cigarette. Background Technology

[0003] Electronic cigarettes work by heating liquid to generate an aerosol, which the user inhales through a drip tip.

[0004] However, conventional drip tips for electronic cigarettes had a problem where, when a user inhales, fine liquid rises along the inner wall of the drip tip along with the aerosol and enters the user's mouth, causing liquid spitting. This liquid spitting phenomenon occurs as fine liquid generated by an aerosol generator (pod) rises along the inner wall of the drip tip like a capillary action due to the user's suction force, and is similar in principle to how water rises along the inner wall of a straw when a straw is inserted into a cup of water and sucked.

[0005] This liquid spitting phenomenon not only causes discomfort to users and detracts from the e-cigarette experience, but also causes the flavor of the liquid to be delivered directly to the mouth, compromising the original user experience of the e-cigarette.

[0006] Conventionally, methods such as installing a filter inside the drip tip or changing the direction of aerosol flow were attempted to prevent such liquid splashing, but these methods had the problem that the taste and aroma of various flavorings (e.g., grape, strawberry, coffee, etc.) added to the liquid were reduced as the aerosol came into contact with the filter or structure. This is because when the direction of aerosol flow is changed or it passes through a filter, it acts as a filter, causing the flavor components to be lost.

[0007] Therefore, there was a need to develop a drip tip that effectively prevents liquid splashing without obstructing the flow of aerosols, preserves flavor, and is easy to maintain. The problem to be solved

[0009] The purpose of this specification is to provide a drip tip that effectively blocks fine liquid from entering the user's mouth when using an electronic cigarette.

[0010] The technical problems that this specification aims to solve are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this specification belongs from the detailed description of the specification below. means of solving the problem

[0012] One aspect of the present specification comprises a drip tip mounted on an aerosol generator for an electronic cigarette, the drip tip comprising: a first body connected to the aerosol generator and through which an aerosol generated by the aerosol generator passes; and a second body having one end connected to the first body and forming an internal passage through which the aerosol passes while connected to the first body; wherein the second body includes an inner protrusion that protrudes from the other end, where a mouth opening is formed, toward the inside of the second body and toward the first body, and the inner protrusion may include a drip tip for preventing liquid splashing, wherein a through hole through which the aerosol passes is formed at one end facing the first body, and the other end facing the mouth opening is open so that the aerosol is discharged.

[0013] A liquid blocking space is formed inside the second body, defined by the inner surface of the second body and the outer surface of the inner protrusion, so that fine liquid moving along the inner surface of the second body can be blocked from being discharged to the suction port.

[0014] The second body may further include a housing portion constituting an external shape, and the inner protrusion may be located inside the housing portion. In this case, the inner diameter of the inner protrusion may be smaller than the inner diameter of the housing portion.

[0015] The inner surface of the second body and the outer surface of the inner protrusion can form a continuous surface, thereby blocking the external discharge of fine liquid moving along the inner surface of the second body through the suction port by the inner protrusion.

[0016] A fine liquid moving along the inner surface of the second body can be temporarily accommodated in the liquid blocking space, and the fine liquid accommodated in the liquid blocking space can fall toward the first body by gravity.

[0017] When negative pressure is formed in the suction port by the user's inhalation, the fine liquid moving along the inner surface of the second body is contained in the liquid blocking space, and the aerosol can be discharged to the suction port through the interior of the inner protrusion.

[0018] By forming the inner protrusion above, the flow path of the aerosol and the movement path of the micro-liquid can be structurally separated.

[0019] Screw threads may be formed on the outer surface of the mounting portion of the first body, and a packing member may be disposed in the screw groove between the screw threads to seal the aerosol generating device and the first body. Effects of the invention

[0021] According to an embodiment of the present specification, a drip tip for preventing liquid splashing can be provided, which can effectively block fine liquid from entering the user's mouth when using an electronic cigarette.

[0022] In addition, according to the embodiments of the present specification, a drip tip for preventing liquid splashing can be provided, which can maintain the original taste and aroma of the electronic cigarette liquid by selectively blocking only the liquid without changing the flow direction of the aerosol.

[0023] In addition, according to the embodiments of this specification, a drip tip for preventing liquid splashing can be provided, which is easy to manufacture with a simple structure and universally applicable to existing electronic cigarette devices. The effects obtainable in this specification are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which this specification belongs from the description below.

[0032] FIG. 1 is a drawing showing a drip tip for preventing liquid splashing according to one embodiment of the present invention, and FIG. 2 is an exploded perspective view showing the state before fastening of the first body and the second body of FIG. 1.

[0033] A drip tip (10) for preventing liquid splashing according to one embodiment of the present invention may be mounted on an aerosol generator (not shown) for electronic cigarettes. The aerosol generator (not shown) for electronic cigarettes is a device that generates aerosol by heating a liquid, and may include a liquid storage unit (pod or cartridge), a heating unit (coil or heater), a battery, etc. A mounting area for mounting the drip tip (10) is formed on the upper part of the aerosol generator (not shown), and the drip tip (10) for preventing liquid splashing according to the present invention may be detachably attached to the mounting area.

[0034] Specifically, the first body (100) of the drip tip (10) for preventing liquid splashing, to be described later, is directly connected to the upper mounting area of ​​an aerosol generator (not shown) so that the aerosol generated by the aerosol generator (not shown) can flow into the drip tip (10). The user inhales the aerosol through the suction port of the drip tip (10), and at this time, the inlet of fine liquid can be blocked from flowing into the user's mouth by the inner protrusion structure of the present invention.

[0035] As shown in FIGS. 1 and 2, the liquid splash prevention drip tip (10) may include a first body (100) connected to the aerosol generating device (not shown). The first body (100) has a first flow path (FL1) through which the aerosol generated by the aerosol generating device (not shown) passes. in It may have an internal structure including (see Fig. 3).

[0036] The first body (100) may include a mounting portion (110) for mounting to the aerosol generator. For example, the mounting portion (110) of the first body (100) may be fastened to the aerosol generator (not shown) in a male-female coupling manner or a screw coupling manner. For example, to be fastened in a screw coupling manner, screw threads may be formed on the outer surface of the mounting portion (110) of the first body (100), and the aerosol generator (not shown) may include a screw fastening structure corresponding to the mounting portion (110) so that the mounting portion (110) of the first body (100) can be inserted. By means of such a screw coupling structure, the first body (100) is firmly fastened to the aerosol generator (not shown) while allowing the user to easily replace it as needed.

[0037] In the mounting portion (110) of the first body (100), there is an inlet (H in ) can be formed. The aerosol generated from the aerosol generator (not shown) is in the inlet (H) of the mounting part (110). in It can be introduced into the drip tip (10) for preventing liquid splashing through )

[0038] The drip tip (10) for preventing liquid splashing may include a second body (200) that is connected to a first body (100). One end of the second body (200) is connected to the first body (100), and the other end of the second body (200) may have a shape suitable for the user's oral structure (e.g., a duckbill shape, a cylinder shape, etc.). The other end of the second body (200) has an inhalation port (H) for the user to inhale aerosol. out ) is located, and the intake port (H out The aerosol can be discharged from the second body (200) through the ) duckbill-shaped intake (H out ) can naturally adhere to the shape of the user's lips and provide a comfortable fit.

[0039] The internal structure of the first body (100) may correspond to the internal structure of the second body (200). For example, a first flow path (FL1) located inside the first body (100) through which aerosols pass. in, (See FIG. 3) and a second path (FL2) located in the second body (200) through which the aerosol passes. in, (See Fig. 3) are connected to each other to form a single internal channel (FL in, (See FIG. 3) can form a path. For example, the aerosol generated from an aerosol generator (not shown) can form a first path (FL1 in, (See FIG. 3) The aerosol can flow from an aerosol generator (not shown) to a second body (200). The aerosol flows through the second flow path (FL2) of the second body (200). in, (See FIG. 3) It can be introduced into the user's mouth or lungs through the internal path (FL in, (See FIG. 3) through which it can be introduced from an aerosol generator (not shown) into the user's mouth or lungs. Due to this continuous internal flow path structure, the flow of the aerosol is maintained smoothly, so that the original taste and aroma of the electronic cigarette liquid can be delivered without loss.

[0040] A mounting part (110) described above may be located at one end of the first body (100), and a first fastening part (120) may be located at the other end of the first body (100). The first fastening part (120) may be configured to be coupled or mounted to the second body (200). A second fastening part (210) may be located at one end of the second body (200). The first fastening part (120) and the second fastening part (210) may be coupled or fastened to each other, and through this, the first body (100) and the second body (200) may be coupled or fastened to each other to form a single drip tip (10). For example, the first fastening part (120) and the second fastening part (210) may be coupled or fastened to each other in a male-female coupling manner. For example, the first fastening part (120) is a male screw inserted into the second fastening part (210), and the second fastening part (210) may be a female screw.

[0042] Figure 3 is a cross-sectional view showing an example of a cross-section of the liquid splash-proof drip tip of Figure 1.

[0043] As illustrated in FIG. 3, the second body (200) may include an inner protrusion (212) that protrudes toward the inside of the second body (200) and the first body (100) from the other end where the suction port (Hout) is formed. For example, at one end of the inner protrusion (212) facing the first body (100), a through hole (212h) through which the aerosol passes is formed, and the suction port (H out The other end facing the aerosol may be opened to the outside so that the aerosol can be discharged.

[0044] The other end of the second body (200) may have a shape that curls inward toward the interior of the second body (200). As a result, the outer surface (211o) of the second body (200) and the inner surface (212i) of the inner protrusion (212) may form a continuous surface, and the inner surface (211i) of the second body (200) and the outer surface (212o) of the inner protrusion (212) may form a continuous surface. Due to this continuous surface shape, fine liquid rising along the inner surface (110i, 120i) of the first body (100) can move to the inner surface (211i) of the second body (200), and the fine liquid can be (temporarily) contained in the liquid blocking space (A1) to be described later along the inner surface (211i) of the second body (200). Through this, the efficiency of micro-liquid blocking can be increased.

[0045] A liquid blocking space (A1) may be formed inside the second body (200), defined by the inner surface (211i) of the second body (200) and the outer surface (212o) of the inner protrusion (212). The liquid blocking space (A1) may be a space formed by the inwardly curved shape of the other end of the second body (200).

[0046] Thanks to the shape of the inner protrusion (212), the inner protrusion (212) or the liquid blocking space (A1) allows the phenomenon in which fine liquid moving along the inner surface (211i) of the second body (200) moves to the aerosol discharge space or the intake port (H out The phenomenon of discharge through ) can be blocked or reduced. By means of the inner protrusion (212) or the liquid blocking space (A1), the suction port (H) of the fine liquid moving along the inner surface (211i) of the second body (200) out External discharge through ) can be blocked.

[0047] Importantly, this liquid blocking mechanism does not alter or obstruct the aerosol flow path. The aerosol discharge space (A2) formed inside the inner protrusion (212) is the intake port (H) from the through hole (212h).out It is connected in a straight line up to ), so the aerosol can flow freely without coming into contact with filters or curved structures. Therefore, it has the effect of delivering the taste and aroma of various flavorings added to the e-cigarette liquid to the user without reduction or deterioration.

[0048] For example, fine liquid traveling along the inner surface (211i) of the second body (200) can be temporarily contained in the liquid blocking space (A1). As the fine liquid is temporarily contained in the liquid blocking space (A1), the fine liquid may be blocked or prevented from entering the user's mouth even if the user inhales the aerosol. This allows the user to use the electronic cigarette comfortably without the discomfort caused by liquid splashing.

[0049] For example, when a user inhales an aerosol, if negative pressure formed by the user is applied to the inhalation port (Hout), the aerosol moves from the aerosol forming device to the user through the drip tip (10), and the fine liquid moving along the inner surface of the second body (200) can be temporarily received in the liquid blocking space (A1). The user inhales the inhalation port (H out When positive pressure is applied to the intake port (Hout) by removing the mouth or blowing exhaled air, the fine liquid contained in the liquid blocking space (A1) can fall towards the first body (100) by gravity. The liquid that falls in this way can be returned to an aerosol generator (not shown) and reused, thereby preventing liquid waste.

[0050] Generally, the mouthpiece (H) of the drip tip (10) of an aerosol forming device for electronic cigarettes out The device is designed to face the opposite direction of gravity, and the aerosol shape device is positioned in the direction of gravity relative to the drip tip (10). Due to this relative positional relationship, the fine liquid contained in the liquid blocking space can fall towards the first body (100) by gravity.

[0051] As illustrated in FIG. 3, an internal channel (FL) formed to extend in a first direction in ) can be formed across the first body (100) and the second body (200). Internal flow path (FL in ) can mean the path through which an aerosol passes, as described above.

[0052] The first body (100) includes a mounting portion (110) that is mounted on an aerosol generator (not shown), and on the outer surface (110o) of the mounting portion (110), screw threads for screw coupling and screw grooves between the screw threads are formed, and packing members (R2, R3) containing an elastic material may be disposed in the screw grooves. The packing members (R2, R3) may be configured to seal the space between the aerosol generator (not shown) and the first body (100). By means of these packing members (R2, R3), the aerosol may not leak to the outside and airtightness between the drip tip (10) and the aerosol generator (not shown) may be ensured.

[0053] The first body (100) includes a first fastening part (120) that is fastened to the second body (200) (or the second fastening part (210) of the second body (200)), and on the outer surface (120o) of the first fastening part (120), screw threads for screw connection and screw grooves between the screw threads are formed, and a packing member (R1) containing an elastic material may be disposed in the screw grooves. The packing member (R1) may be configured to seal the space between the first body (100) and the second body (200). The inner surface (120i) of the first fastening part (120) may form a continuous surface with the inner surface (211i) of the second body (200) (when the first body (100) and the second body (200) are fastened).

[0054] The second body (200) includes a second fastening part (210), and when the first body (100) and the second body (200) are fastened, the second fastening part (210) can cover the outer surface (120o) of the first fastening part (120). Accordingly, the inner surface (120i) of the second fastening part (210) can come into direct contact with the outer surface (120o) of the first fastening part (120).

[0055] The second body (200) may include a housing portion (211) constituting an external shape and an internal protrusion portion (212) protruding inward. In this specification, the outer surface (211o) of the second body (200) may refer to the outer surface (211o) of the housing portion (211), and the inner surface (211i) of the second body (200) may refer to the inner surface (211i) of the housing portion (211). One end of the housing portion (211) may be formed to extend toward the first body (100) as a second fastening portion (210). The other end of the housing portion (211) may be formed to extend in a direction opposite to the direction toward the first body (100).

[0056] The other end of the housing portion (211) is connected to the other end of the inner protrusion (212), and the other end of the housing portion (211) may have a shape that curls inward toward the interior of the second body (200). As a result, a liquid blocking space (A1) defined by the inner surface (211i) of the second body (200) and the outer surface (212o) of the inner protrusion (212) may be formed inside the second body (200). The liquid blocking space (A1) may be a space formed by the curled-in shape of the other end of the housing portion (211).

[0057] A through hole (212h) is formed at one end of the inner protrusion (212), and an aerosol can be introduced into the inner space (A2) of the inner protrusion (212) through the through hole (212h). (212) The inner space (A2) is an intake port (H outIt is a space connected to ), and may be a space where sound pressure is formed by the user. A filter member (Ft) may be attached to the through hole (212h), and the filter member (Ft) may be a replaceable component. The filter member (Ft) is placed in the space between the first body (100) and the second body (200), and the internal flow path (FL in It can be placed on the ). The aerosol can pass through the filter member (Ft) first and then through the through hole (212h), and for this purpose, the filter member (Ft) can be attached to the outer surface (212o) of the inner protrusion (212).

[0058] Referring to FIG. 3, the user [has] an intake port (H out The operating mechanism when inhaling aerosols through ) can be explained. First, by the user's inhalation, the inhalation port (H out When negative pressure is formed in ), the aerosol generated by the aerosol generator (not shown) is in the inlet (H) of the first body (100). in It can be introduced into the drip tip (10) through ). At this time, fine liquid also moves from the pod along with the aerosol, and the aerosol is directly introduced into the internal space of the inner protrusion (212) through the through hole to the intake port (H out While being discharged, the fine liquid may rise along the inner surface of the first body (100) and the second body (200) and be captured in the liquid blocking space (A1). For example, the liquid blocking space (A1) may surround the inner protrusion (212) or the outer surface (212o) of the inner protrusion (212).

[0059] Meanwhile, when the user stops inhaling or blows exhaled air, the intake port (H out Positive pressure is formed in the liquid blocking space, and the fine liquid contained therein falls towards the first body (100) by gravity and can finally return to the pot.

[0060] For reference, the liquid splash prevention drip tip (10) according to one embodiment is based on the principle of the air circulation effect inside an umbrella, and by structurally separating the path through which the liquid moves and the path through which the aerosol flows, it is possible to prevent liquid splashing while simultaneously preserving the flavor of the aerosol.

[0061] Specifically, the inner protrusion (212) forms an independent path through which the aerosol flows, and the fine liquid rising along the inner surface (211i) of the second body (200) is captured in the liquid blocking space (A1) formed on the outer side of the inner protrusion (212) and cannot enter the aerosol flow path. This is a principle similar to that of an umbrella dome shape, which enables internal air circulation while preventing the penetration of rainwater.

[0062] Thus, the liquid splash prevention drip tip (10) of the present invention effectively blocks liquid splashing with only a simple inner protrusion (212) structure, while not obstructing the flow of aerosol, thereby maintaining the original taste and aroma of the electronic cigarette. In addition, it has the advantage of being easy to manufacture due to its simple structure and universally applicable to various aerosol generating devices (not shown).

[0063] The results of testing the conventional filter-type drip tip (10) and the liquid splash prevention drip tip (10) of the present invention under the same conditions for one month are as follows.

[0064] [Comparative Example 1] Filter method

[0065] - Anti-splashing effect: Good

[0066] - Flavor retention: Poor (Users clearly perceive flavor loss)

[0067] - Maintenance: Filter replacement required every 2 weeks

[0068] [Example 1] The present invention

[0069] - Anti-splatter effect: Excellent (Confirmed elimination of liquid splattering on all devices)

[0070] - Flavor preservation: Excellent (Aerosol does not come into contact with filters, etc.)

[0071] - Maintenance: Unnecessary (Structural solution)

[0072] From the above results, it can be confirmed that the liquid splash prevention drip tip (10) of the present invention effectively prevents liquid splashing while preserving flavor and requiring no maintenance.

[0073] Additionally, the filter member (Ft) may include a plurality of filter layers. For example, the filter member (Ft) may include a filter layer (Ft1), a first functional layer (Ft2), and a second functional layer (Ft3).

[0074] The filter layer (Ft1) is positioned so as to be furthest from the through hole (212h), the second functional layer is positioned so as to be closest to the through hole (212h), and the first functional layer may be positioned between the filter layer and the second functional layer.

[0075] For example, the filter layer (Ft1) can filter out impurities that may be inhaled by the user in addition to the fine liquid. The filter layer (Ft1) is formed of a material having a porous structure and can capture fine particles or impurities. Due to the positional characteristics of the filter layer (Ft1), the filter layer (Ft1) may filter impurities but may not filter the flavor enhancer of the first functional layer (Ft2).

[0076] For example, the first functional layer (Ft2) may include a flavor enhancer to enhance the flavor of the aerosol to be provided to the user. The flavor enhancer may include various flavor components such as menthol, fruit flavor, and herbal flavor, and the user may enjoy various flavors depending on the flavor enhancer included in the drip tip (10) by exchanging the drip tip (10) according to their preference. The flavor enhancer of the first functional layer (Ft2) may be configured so that the flavor components are slowly released as the aerosol passes through.

[0077] For example, the second functional layer (Ft3) may include a hygroscopic material for controlling the humidity of the aerosol. The second functional layer (Ft3) may include at least one of silica gel, zeolite, and a hygroscopic polymer material, and can absorb excess moisture from the aerosol passing through the through hole (212h) to control the humidity to an appropriate level. This optimizes the density and texture of the aerosol delivered to the user, thereby providing a soft and pleasant sensation of inhalation.

[0078] In particular, the second functional layer (Ft3) has an intake port (H out By being positioned closest to the filter element (Ft), humidity control can be achieved at the final stage where the aerosol enters the filter element (Ft), thereby delivering a softer flavor to the user.

[0079] As the filter layer (Ft1), the first functional layer (Ft2), and the second functional layer (Ft3) of the filter member (Ft) are arranged in the above order, the following organic synergistic effect can be achieved.

[0080] First, the temperature gradient optimization effect can be achieved. As the aerosol passes through the filter element (Ft), the temperature is lowered in stages, and each layer is arranged so that it can function within an optimal temperature range. Immediately after passing through the through hole (212h), the aerosol is at a relatively high temperature (about 50-70°C), and since impurities move more actively at high temperatures in the filter layer (Ft1), the capture efficiency of the filter layer (Ft1) can be increased, and some moisture can be condensed to achieve primary humidity control. In the first functional layer (Ft2), the release of the flavor enhancer is optimized at an intermediate temperature (about 40-55°C), and in this temperature range, the vapor pressure of the flavor component is appropriate, allowing it to be released uniformly without excessive volatilization. In the second functional layer (Ft3), the hygroscopic ability of the hygroscopic material is stably maintained at a lowered temperature (about 30-45°C). At very high temperatures, the hygroscopic material may release the absorbed moisture, but at lowered temperatures, it can stably retain moisture. The temperature of the aerosol finally delivered to the user is about 30-40°C, which can be a comfortable temperature for the mouth and throat.

[0081] Second, a flavor maturation effect can be achieved. Flavor components released from the first functional layer (Ft2) can be 'matured' at appropriate humidity and temperature while passing through the second functional layer (Ft3), transforming into a softer and richer flavor. Flavor components released from the flavor enhancer may be relatively sharp and intense, but during the short time (about 0.1-0.3 seconds) passing through the second functional layer (Ft3), the flavor components can undergo a maturation process as they mix with an aerosol of appropriate humidity. In this process, highly volatile and irritating components are partially removed, and medium-volatile, soft flavor components become dominant. Additionally, the complexity and depth of the flavor can increase as the flavor components and moisture temporarily interact on the surface of the hygroscopic material of the second functional layer (Ft3). Consequently, the user can experience a rich and balanced flavor rather than simply a strong aroma.

[0082] In this way, the sequential arrangement of the filter layer (Ft1), the first functional layer (Ft2), and the second functional layer (Ft3) can achieve complex technical effects by creating a synergistic effect through inter-layer interaction, going beyond simply performing the function of each layer independently.

[0083] Although the embodiments have been described above, they are merely examples and are not intended to limit the scope of this specification. Those skilled in the art will understand that various modifications and applications not exemplified above are possible within the scope of the essential characteristics of the embodiments. For example, each component specifically shown in the embodiments may be modified and implemented.
