Description

Technical Field

[0001] The utility model relates to a personal vaporizer device and an exemplary embodiment more particularly to a device and a method for releasably locking a mouthpiece to a vaporizer cartridge. Background Art

[0002] In the past several years, personal vaporization devices (also known as vaporizers or electronic cigarettes or atomizers, among other names) have become substantially popular. These devices typically include a cartridge having a container that contains a vaporized liquid (typically referred to as e-liquid or plant-based oil extract) that is vaporized for inhalation by the user. These e-liquids or plant-based oil extracts typically contain, for example, but not limited to, nicotine. Therefore, with the popularity of these devices, there has arisen the problem of keeping e-liquids out of reach of children. Therefore, these devices typically have a child-resistant structure having components including, for example, but not limited to, a mouthpiece and a cartridge that are permanently connected when assembled together so as to seal the contents of the e-liquid to prevent it from being undesirably accessed.

[0003] All current mouthpiece locking mechanisms are permanently attached. A disadvantage of such permanently attached mouthpiece locking mechanisms is that the mouthpiece connection cannot be unlocked, making it impossible to access the cartridge container without damaging or destroying the device, which effectively prevents refilling of the container. Another disadvantage of permanently attached mouthpiece locking mechanisms is that the e-liquid in the container cannot be accessed for legitimate non-e-cigarette purposes, such as for testing. This makes it difficult for testing laboratories to access the e-liquid, such as for heavy metal testing. In order to access the e-liquid, the mouthpiece needs to be destroyed or cut off using a tool. During this destructive removal process, the e-liquid may be contaminated with debris from the cartridge that may include heavy metals, resulting in failed test results.

[0004] Therefore, a releasable mouthpiece locking mechanism is needed. Such a releasable mouthpiece locking mechanism will prevent potential test failures caused by contamination during the destructive removal of the mouthpiece. Such a releasable mouthpiece locking mechanism is more advantageous, for example, in the event of a malfunction, because it can prevent access to the e-liquid while also allowing the mouthpiece to be removed to save the contents of the cartridge, the e-liquid, or the plant-based oil extract. If such a releasable mouthpiece locking mechanism can allow for low torque capping and multiple capping capabilities, it will be advantageous for efficient manufacturing. It will be even more advantageous if the releasable mouthpiece locking mechanism is child-proof to ensure safety. It will be further advantageous if the locking mechanism can be released by a simple release mechanism. Utility Model Content

The first surface 182 tapers away from the cartridge 200 toward the first longitudinal axis 300, and the fourth surface 232 has a complementary taper pointing away from the mouthpiece 100 and away from the first longitudinal axis 300. A force is applied to push the mouthpiece 100 and the cartridge 200 together so that the two or more first hook portions 180A slide on the fourth surface 232 and flex radially away from the longitudinal axis 300. While continuing to apply force to the mouthpiece 100, the two or more first hook portions 180A snap onto the shoulder 220 so that the second surface 184 on each of the two or more first hook portions 180A contacts the fifth surface 234 on the shoulder 220.

[0114] like Figure 4 As shown in , in this assembled state, because the second surface 184 and the fifth surface 234 are parallel and in contact, the mouthpiece 100 is locked to the cartridge 200. This locked mouthpiece is child-resistant because the force applied to the mouthpiece 100 to separate it from the cartridge 200 cannot remove the mouthpiece 100 without destroying the shoulder 220 and at least one of the two or more first hook portions 180A, and children generally do not have the strength to apply enough force to destroy one of these components. However, as further described below, the locked mouthpiece mechanism including the mouthpiece 100 and the cartridge 200 can be released by a simple release mechanism.

[0115] Figure 5 and Figure 6 Such an exemplary release mechanism is shown in the form of a release pin (pin) 400 applied to a double hook arm 180. For clarity, Figure 5 and Figure 6 The support structure 130 is shown without the surrounding mouthpiece housing 150 . Figure 5 The two or more second hook portions 180B shown are arranged corresponding to Figure 4 To further assist in describing the release mechanism, now Figure 4 and Figure 5 Some exemplary distances are defined and shown in FIG.

[0116] The distance between the two opposing first hook portions 180A is defined as a first distance D1. The distance between the two opposing second hook portions 180B is defined as a second distance D2. The distance between the radially outer surfaces of the shoulders 220 is defined as a third distance D3. The exemplary pin 400 having any desired cross-sectional shape has a minimum cross-sectional dimension Dp. For simplicity, all defined distances will be described for circular geometries so that these distances are diameters, however, for non-circular geometries, these distances may be the minimum distances for the mechanism to function properly, as will be described.

[0117] Reference again Figure 4 and Figure 5 , the diameter Dp of the pin 400 is greater than the second distance D2. To achieve release of the mouthpiece 100, the pin 400 is pushed through the second channel 110 and the first channel 170 in the direction of arrow 410 and contacts the third surface 186, which is angled along the direction of movement of the pin 400 (which is along the longitudinal axis 300), as described above and for example in Figure 5 and Figure 6 A force is further applied to the pin 400 against the third surface 186 so that the pin 400 slides longitudinally along the third surface 186, thereby pushing the plurality of second hook portions 180B apart and away from the longitudinal axis 300. Due to the connection of the second hook portions 180B to the first hook portions 180A, the displacement of the second hook portions 180B away from the longitudinal axis 300 causes the displacement of the first hook portions 180A away from the longitudinal axis 300.

[0118] Reference now Figure 6 , the pin 400 has now been pushed far enough through the second passage 110 of the mouthpiece 100 to be located between the second hook portions 180B, which are visibly displaced radially away from the longitudinal axis 300. Figure 6 In the state shown, as long as the second hook portion 180B is displaced far enough away from the longitudinal axis 300 so that the first hook portion 180A is also displaced far enough away from the longitudinal axis 300 to a first distance D1 greater than the third distance D3, the mouthpiece 100 can be released from the cartridge 200. The actual distance that the second hook portions 180B must be spaced apart, and thus the actual required diameter of the pin 400, depends on several factors, including, for example, but not limited to, the flexibility and thickness of the first hook portions 180A and the second hook portions 180B of the two or more double hook arms 180, and the actual distance that the second hook portions must be spaced apart and the actual required diameter of the pin can be adjusted according to, for example, but not limited to, the requirements of the locking tolerance and the force required to break or other considerations.

[0119] In an embodiment, the support structure 130 including the double hook arms 180 is made of, for example but not limited to, plastic injection through an injection molding process. In an embodiment, the support structure 130 including the double hook arms 180 is made of plastic, for example but not limited to, polyethylene cyclohexylene dimethyl terephthalate (PCTG), polyamide nylon (PA), polypropylene (PP), and various other plastics known in the art.

[0120] For example, a molded support structure 130 made by such a process may be formed by injecting a liquid or molten material (such as, but not limited to, a plastic selected from the types of plastics listed above) into a mold, allowing the liquid or molten material to solidify and / or cool, and then removing the resulting molded support structure 130 from the mold. Examples of such injection molding processes are well known.

[0121] However, because the geometry of the releasable mouthpiece locking mechanism described above includes a physical barrier that resists axial movement in both directions along the longitudinal axis through the locking mechanism, an additional release mechanism can be used to remove the complete molded part from the mold. For example, given the geometry of the support structure 130, and specifically the geometry of the double hook arms 180, as described above Figure 4 As shown in the cross-section in FIG. 1 , any process for manufacturing the support structure 130 by injecting a liquid or molten material into a mold will cause the double hooked arms 180 to lock into the mold. This is because the space between the first hooked portion 180A and the second hooked portion 180B is necessarily formed during the molding process by the radially outwardly directed portion of the mold. Therefore, when the liquid or molten material solidifies, the resulting molded support structure 130 will be locked into place by the radially outwardly directed portion of the mold. Figure 4 The mouthpiece 100 is shown locked to the mold in substantially the same manner as it is locked to the cartridge 200 by a radially outwardly extending shoulder 220 .

[0122] Reference now Figure 7 and Figure 8 , describes an apparatus and method for manufacturing a support structure 130 as a molded component having a double hook arm 180 (including a first hook portion 180A and a second hook portion 180B), the apparatus including a simple mechanism for releasing the double hook arm 180. Figure 7 A schematic cross-sectional view of an assembled exemplary mold apparatus 500 is shown, wherein a blank space representing the support structure 130 can be seen in the mold apparatus. In an embodiment, the mold apparatus 500 includes six main components, which are Figure 7 The symbols are 500A, 500B, 500C, 500D, 500E and 500F. Figure 8A perspective view of a (molded) support structure 130 is shown, including an indication of the position of a first side portion 500A and a second side portion 500B of a mold apparatus 500 relative to the support structure 130 .

[0123] refer to Figure 7 and Figure 8 The outer peripheral surface of the support structure 130 is defined by a first side portion 500A and a second side portion 500B vertically separated along an exemplary slip line 510, the first side portion and the second side portion being defined by Figure 8 Indicated by the arrows labeled 500A and 500B in the figure. In an embodiment, the top portion 500C of the mold device 500 is a single component. However, as will be discussed below, in part due to the placement of the syringe, the top portion 500C can be two or more components.

[0124] refer to Figure 7 , in an embodiment, the central mold portion 500D defines the inner surface of the support structure 130. The central mold portion 500D is alternatively referred to as a mold core 500D. In an embodiment, the ejector pins 500E are disposed along the second longitudinal axis 520 of the mold apparatus 500. In an embodiment, the stripper plate 500F is disposed around the bottom end of the mold core 500D and is radially disposed between the mold core 500D and the first side portion 500A and the second side portion 500B.

[0125] Reference again Figure 7 , based on the assembled mold apparatus 500 shown, the process of material injection can be performed. In an embodiment, the components of the mold apparatus 500 are held together by external compression from the top and sides. In other embodiments, the multiple components of the mold apparatus 500 can be snapped together or otherwise joined together and have external clamps or straps, such as eccentric clamps, which once snapped closed will not open unless forced open by human intervention. The multiple components of the mold apparatus 500 can be held together by other means known in the art for multi-component molds.

[0126] Fig. 9 Schematic representations of embodiments of one or more injection ports 530 are shown that inject liquid or molten material 540 into the mold apparatus 500 at one or more locations within the mold apparatus 500. For clarity of illustration, Fig. 9 The molding support structure 130 is shown instead of the mold device 500. It is intended to illustrate that in embodiments, liquid or molten material is injected through one or more injection ports 530 (for example, but not limited to, through a mold device such as Fig. 91 and 12. In one embodiment, the top portion 500C is a top portion 500C that is used to inject a plurality of injection ports 530A, 530B, 530C, and 530D (shown schematically in FIG. 1 ) into the assembled mold apparatus 500 to produce the support structure 130, wherein each of the one or more injection ports 530A, 530B, 530C, and 530D can inject a liquid or molten material 540 into one or more injection points of the mold apparatus 500. In another embodiment, the one or more injection ports 530 are a single injection port 530 that is moved to multiple injection points within the mold apparatus 500, such as but not limited to, by rotation of the top portion 500C relative to the rest of the mold apparatus 500 or by opening and closing one or more valves (not shown) within the top portion 500C to direct the liquid or molten material to the desired injection point (or multiple desired injection points).

[0127] Having described the structure and function of all components of the mold apparatus 500 above, an exemplary method 600 for producing a support structure 130 using the mold apparatus 500 will now be described. Fig.10 At step 602, the first side portion 500A and the second side portion 500B are assembled together around the stripper plate 500F and the mold core 500D with the ejector pins 500E disposed in the mold core 500D. At step 604, one or more top portions 500C of the mold apparatus 500 are assembled to the assembled mold portions. At step 606, liquid or molten material is injected into the assembled mold apparatus 500 through one or more injection ports 530 disposed through the one or more top portions 500C. At step 608, the liquid or molten material solidifies. At step 610, the one or more top portions 500C are removed. At step 612, the first side portion 500A and the second side portion 500B are removed.

[0128] refer to Fig.11 and Fig.12 , at this point, the remaining components of the mold apparatus 500 in the exemplary method 600 are shown. Fig.11 , viewed from above, showing the molding support structure 130 after the first and second side portions 500A, 500B and the top portion 500C have been removed. In this view, the mold core 500D and the ejector pins 500E are clearly visible. Fig.12 In the cross-sectional view and as previously noted, the support structure 130 is visibly locked to the mold core 500D by the first hook portion 180A and the second hook portion 180B. However, the top portion 550 of the ejector pin 500E contacts the radial inner surface 551 of each second hook portion 180B. The top portion 550 and the radial inner surface 551 of each second hook portion 180B contact along a surface that tapers relative to the second longitudinal axis 520, as shown in FIG. Fig.12 The tapered contact surface between the top portion 550 and the radial inner surface 551 of each second hook portion 180B allows the ejector pin 500E to slide upward relative to the plurality of second hook portions 180B. The upward sliding movement of the ejector pin 500E causes the plurality of second hook portions 180B to separate, as shown in FIG. Fig.13 shown.

[0129] refer to Fig.10 and Fig.13 At step 614, the ejector pin 500E is moved toward the free end of the second hook portion 180B, as indicated by arrow 560. The upward movement of the ejector pin 500E causes the plurality of second hook portions 180B to separate sufficiently so that the first hook portion 180A is completely pulled out of the mold core 500D, as shown in FIG. Fig.13 In an embodiment, at step 616, the mold core 500D is optionally moved away from the free end of the second hook portion 180B and out of the mold apparatus 500, as indicated by arrow 570. However, removal of the mold core 500D at step 616 is optional, and in another embodiment, at step 616, the mold core 500D is not removed but left in place.

[0130] At this point, in method 600, support structure 130 remains disposed on ejector pins 500E. Therefore, in an embodiment, at step 618, support structure 130 is pushed by stripper plate 500F so that the support structure is completely off ejector pins 500E and is also completely released from mold apparatus 500. Alternatively, in an embodiment, for example, with stripper plate 500F fixed, at step 618, ejector pins 500E are moved in a direction opposite to arrow 560 so that support structure 130 is completely off ejector pins 500E and is completely released from mold apparatus 500. In another embodiment, for example, with the stripper plate 500F fixed and the mold core 500D remaining in place at step 616, then at step 618, the mold core 500D and the ejector pins 500E are moved together in the direction of arrow 570 opposite to arrow 560 so that the support structure 130 completely leaves the mold core 500D and the ejector pins 500E and is completely released from the mold apparatus 500.

[0131] Figures 14 to 22 Another embodiment of a mouthpiece assembly providing a releasable mouthpiece locking mechanism is shown. The mouthpiece assembly includes a locking adapter that can seal a cartridge container and can receive an interchangeable mouthpiece housing via a press fit or a friction fit. The locking adapter can be released via a radial compression force applied to a pair of release arms that press against the locking adapter.

[0132] Reference now Fig.14 and Fig.15 , respectively, a mouthpiece assembly 700 including a releasable locking mechanism (RLM) is shown in cross-section at a relative rotation of 90 degrees. In an embodiment, the mouthpiece assembly 700 includes an interchangeable mouthpiece 705 disposed on a locking adapter 710, which is releasably locked to a vaporizing cartridge 715. Only the top end of the cartridge 715 including the conduit 725 and the outer wall 290 can be seen in these figures; however, in an embodiment, the cartridge 715 is similar to the cartridge 200 described above (see Figure 2 ), and includes a conduit 725 having a shoulder 730 extending radially outwardly, which is circumferentially arranged around a first end 735 of the conduit 725 (and the cartridge 715).

[0133] Temporary reference Figure 2 , use with Figure 2 The same reference numerals used in the description of the similar parts of the cartridge 715 are used. Figure 2 The cigarette cartridge 200 in the cigarette cartridge 715 also includes a connecting member 240, which is, for example but not limited to, arranged on the cigarette cartridge 715 (see Figure 2 The threaded connector 240 at the second end 250 of the cartridge 200 in FIG. 240 enables the cartridge 715 to be connected to a power source, such as a battery component (not shown) having a complementary connector, to provide power to the cartridge 715 (see FIG. Figure 2 The heating unit 260 in the cigarette cartridge 200 provides power.

[0134] refer to Fig.14 and Fig.15 In an embodiment, a mouthpiece assembly 700 is shown having an interchangeable mouthpiece 705 attached to a sealing ring 720 by a friction fit of the interchangeable mouthpiece 705 (e.g., by a press fit), as shown. In an embodiment, the locking adapter 710 includes a body portion 740 and a sealing ring 720 disposed about the body portion 740. In an embodiment, the sealing ring 720 is a ring made of an elastically compressible material, such as, but not limited to, an O-ring, which is retained within a circumferential groove 722 disposed about the outer surface of the body portion 740, such as by elastic tension. The sealing ring 720 extends slightly radially above the groove 722, so that the friction connection between the interchangeable mouthpiece 705 and the sealing ring 720 is sufficient to keep the interchangeable mouthpiece 705 attached for use, while also allowing the interchangeable mouthpiece 705 to be attached only by moving the seal ring 720 longitudinally (in the longitudinal direction) relative to the sealing ring 720. Fig.14 and Fig.15 The interchangeable mouthpiece 705 is pulled upward along the third longitudinal axis 718 to slide the interchangeable mouthpiece 705 away from the sealing ring 720.

[0135] The interchangeable aspect of the interchangeable mouthpiece 705 allows for the use of a variety of different interchangeable mouthpieces 705 (see Fig.16 ), for example, mouthpieces with different shapes and hole sizes are interchangeable according to the needs or expectations of the user. In an embodiment, the interchangeable mouthpiece 705 is made of a rigid material that resists radial compression forces applied to the outer peripheral surface of the interchangeable mouthpiece 705. In another embodiment, the interchangeable mouthpiece 705 is made of an elastic and flexible material that elastically flexes inwardly in response to radial compression forces applied to the outer peripheral surface of the interchangeable mouthpiece 705. As further described below, an embodiment of the mouthpiece assembly 700 including an elastic and flexible interchangeable mouthpiece 705 is releasable without removing the interchangeable mouthpiece 705 from the locking adapter 710.

[0136] Reference again Fig.14 and Fig.15 In an embodiment, the body portion 740 further includes a sealing cap ring 750 disposed on an inwardly facing end 760 of the body portion 740. In an embodiment, the sealing cap ring 750 is a ring of a resiliently compressible material. In an embodiment, the inwardly facing end 760 includes a radially outwardly facing shoulder 762 that prevents the sealing cap ring 750 from disengaging. In an embodiment, the sealing cap ring 750 is sized to have a radial annular width greater than the distance between the inner surface of the outer wall 290 and the outer surface of the pipe 725. In an embodiment, when the locking adapter 710 is releasably locked to the pipe 725 (as fully described below), the sealing cap ring 750 compresses to form a seal between the inner surface of the outer wall 290 and the outer surface of the pipe 725.

[0137] As in Fig.14 and Fig.15 As can be seen in the drawings, in embodiments, the conduit 725 can engage one or more ribs 766 extending radially inwardly from the sealing cap ring 750. In other embodiments, the sealing cap ring 750 is devoid of ribs 766.

[0138] refer to Fig.17 , shows in perspective an embodiment of a locking adapter 710 releasably attached to a pipe 725 with the interchangeable mouthpiece 705 removed. The locking adapter 710 includes a base portion 770 supporting a sealing ring 720. A fixed wall 780 and opposing release arms 790 extend longitudinally from the base portion 770. Although two fixed walls 780 are shown, more than two fixed walls 780 may be distributed circumferentially in the space between the opposing release arms 790. Fig.18 and Fig.19 Two additional perspective views of the locking adapter 710 are shown, both showing the securing wall 780 and the opposing release arm 790 .

[0139] Reference now Fig. 20 , shows an embodiment of the locking adapter 710 in a cross-sectional view taken through the opposing release arms 790. In an embodiment, each release arm 790 includes an inner portion 795 and an outer portion 800. Fig.21 In an embodiment, the relative release arm 790 including the inner portion 795 and the outer portion 800 is elastic and flexible at least at two opposite longitudinal ends of each of the inner portion 795 and the outer portion 800, so that each of the inner portion 795 and the outer portion 800 can be elastically flexed or bent in a radial direction in response to an applied force. For example, the outer portion 800 is elastic and flexible at least at the end 802 (where each outer portion 800 is attached to the base portion 770). Similarly, the inner portion 795 is elastic and flexible at least at the end 804 (from which each inner portion 795 extends).

[0140] In an embodiment, the radially outwardly extending shoulder 730 at the first end 735 of the tube 725 includes a truncated corner or angled corner 737 adjacent the first end 735. In an embodiment, the radially outwardly extending shoulder 730 also includes a generally vertical overhang 739 located on both longitudinal ends of the radially outwardly extending shoulder 730 opposite the truncated corner or angled corner 737, and each inner portion 795 includes a radially inwardly directed hook 742 located on its free end.

[0141] Fig. 20 The locking adapter 710 is shown disposed on the pipe 725 in a releasably attached state, wherein the hook portion 742 longitudinally engages the generally vertical overhang 739 to prevent the locking adapter 710 from being removed from the pipe 725. Fig.21 Also schematically shown is a portion of the locking adapter 710 including a release arm 790 shown in a released position relative to the pipe 725.

[0142] refer to Fig.21 In an embodiment, when a radial compressive force (such as, but not limited to, applied between one finger and thumb of a user) is applied to the outer side of the release arm 790, the locking adapter 710 is released, such as Fig.21 Depending on the type of interchangeable mouthpiece 705, the radial compressive force may be applied with the interchangeable mouthpiece 705 removed or with the interchangeable mouthpiece 705 held in place on the locking adapter 710. Fig.21705, a portion of the resilient and flexible interchangeable mouthpiece 705 is shown in dashed lines to illustrate this point. In the embodiment in which the mouthpiece assembly 700 includes a rigid interchangeable mouthpiece 705, after the interchangeable mouthpiece 705 is removed, a radial compressive force F1 is applied to two opposite sides of the release arm 790, as shown. In the embodiment in which the mouthpiece assembly 700 includes a resilient and flexible interchangeable mouthpiece 705, when the interchangeable mouthpiece 705 is held in place on the locking adapter 710, a radial compressive force F2 is applied to two opposite outer surfaces of the interchangeable mouthpiece 705, which is directed to two opposite sides of the release arm 790, as shown.

[0143] In an embodiment, the outer portion 800 of the release arm 790 elastically flexes inwardly in response to the radial compressive force F1 or F2, as indicated by arrow 744. In an embodiment, due to this elastic flexure, the radially innermost edge of the top end portion of the release arm 790 is pushed toward the third longitudinal axis 718, so that the radially innermost edge of the top end portion of the release arm 790 is located radially inward of the truncated corner or angled corner 737. In an embodiment, in response, each inner portion 795 effectively elastically pivots on the truncated corner or angled corner 737 and elastically flexes outwardly away from the third longitudinal axis 718, as indicated by arrow 746. In an embodiment, the outward elastic flexure of the inner portion 795 effectively pulls the hook portion 742 away from the pipe 725 and out of longitudinal engagement with the generally vertical overhang 739. As a result, in Fig.21 In the position shown, in embodiments, the releasable locking adapter 710 is released from the pipe 725 and can be moved longitudinally (in Fig.21 Pull it out of pipe 725 by pulling it upward in the middle.

[0144] Reference now Fig. 22 , shows an interior portion of an interchangeable mouthpiece 705 in an embodiment. In an embodiment, one or more ribs 810 extend generally vertically along an inner surface 820 of the interchangeable mouthpiece 705. The one or more ribs 810 can be present on the interchangeable mouthpiece 705 of either a resilient and flexible or rigid type. When the interchangeable mouthpiece 705 is press-fitted onto the locking adapter 710, the one or more ribs 810 prevent swinging of the interchangeable mouthpiece 705 by, for example, providing a tighter fit or tolerance between the inner surface 820 and the outer surface of the locking adapter 710.

[0145] In an embodiment, the mouthpiece assembly 700 including the interchangeable mouthpiece 705, the releasable locking adapter 710 and all the components associated therewith described above is made of, for example, but not limited to, plastic injection using a mold. In an embodiment, as described above, the mouthpiece assembly 700 including the interchangeable mouthpiece 705, the releasable locking adapter 710 and all the components associated therewith described above is made of plastic, for example, but not limited to, polycarbonate (PC), polyethylene cyclohexane dimethyl terephthalate (PCTG), polyamide nylon (PA), polypropylene (PP) and various other plastics known in the art.
