Description

Technical Field

[0001] This utility model relates to the field of electronic atomizers, and in particular to an airway sealing structure and an electronic atomizer having the airway sealing structure. Background Technology

[0002] Electronic atomizers, as a new type of smoking alternative, have been widely used in recent years. Electronic atomizers atomize e-liquid in the tank through an atomizer coil. Gas is drawn in through the air intake of the electronic atomizer, which transports the vapor generated by the coil to the inhalation end of the electronic atomizer, thus simulating the experience of traditional smoking. However, existing electronic atomizers often have the problem of e-liquid leakage in the tank during actual transportation. Because e-liquid is a liquid, when the electronic atomizer is bumped or negative pressure is created during air transport, e-liquid may flow out from the air intake, resulting in e-liquid leakage. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] An airway sealing structure includes a base with a first cavity inside. An insertion hole is provided at the bottom of the base, which communicates with the first cavity. An airflow valve is provided at the bottom of the base. The air outlet of the airflow valve is inserted into an insertion hole to allow air to flow from the bottom of the airflow valve into the base. A sealing element is provided inside the base, and the sealing element has a first through hole. The air outlet of the airflow valve is inserted into one end of the first through hole and can slide out or retract into the first through hole from the other end of the first through hole. The airway sealing structure also includes a locking module to block the air outlet of the airflow valve in the first through hole, thereby preventing the airflow valve from conducting air.

[0005] The locking module includes a locking component and a first limiting component located at the air inlet end of the airflow valve. The locking component is located on the bottom surface of the base near the insertion hole. When the airflow valve is inserted into the insertion hole, the first limiting component gradually approaches the locking component until it abuts against one end of the locking component. The other end of the locking component abuts against the bottom surface of the base, thus limiting the insertion depth of the airflow valve. At this time, the end of the airflow valve located in the first cavity can only be inserted into the sealing component.

[0006] As a further embodiment of this utility model, the locking module also includes a second limiting member disposed on the outer surface of the airflow valve. When the airflow valve is inserted into the insertion hole, the second limiting member is inserted into the insertion hole along with the airflow valve, and one end of the second limiting member near the insertion hole is locked in the inner opening of the insertion hole.

[0007] As a further embodiment of this utility model, the thickness of the locking member is not less than the distance between the outlet end of the airflow valve and the other end of the first through hole.

[0008] As a further embodiment of this utility model: the clip is provided with a fitting part, which is arc-shaped and used to fit the outer surface of the airflow valve.

[0009] As a further embodiment of this utility model: the airflow valve is provided with at least one air guide hole at one end of the first cavity.

[0010] As a further embodiment of this utility model: the first limiting member and the airflow valve are integrally formed, and the second limiting member and the airflow valve are integrally formed.

[0011] As a further embodiment of this utility model, it also includes a sealing groove on the top of the sealing element, oil-absorbing cotton for absorbing e-liquid, a bracket, and a sealing sleeve on the top of the bracket. The oil-absorbing cotton is placed in the sealing groove and has a second through hole that connects to the first through hole. The bracket extends downward and has an insertion part for snapping into the inner wall of the sealing groove. The top of the bracket has a third through hole that connects to the second through hole. The sealing sleeve is snapped into the top of the bracket and has a fourth through hole that connects to the third through hole.

[0012] As a further embodiment of this utility model: the sealing element, the locking element, and the sealing sleeve are all made of silicone.

[0013] As a further embodiment of this invention: an electronic atomizer, including the aforementioned airway sealing structure.

[0014] As a further embodiment of this utility model, it also includes an oil tank and an atomizing core assembly. One end of the oil tank is provided with a mouthpiece for inhalation, and the other end of the oil tank is provided with a second cavity. The other end of the oil tank is installed on the top of the sealing sleeve. The atomizing core assembly is located in the second cavity. One end of the atomizing core assembly passes through the fourth through hole and is inserted into the third through hole. The other end of the atomizing core assembly is connected to the mouthpiece.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an air passage sealing structure, when the electronic atomizer is transported, the locking component is installed between the first limiting component of the airflow valve and the bottom surface of the base, which restricts the depth of the airflow valve inserted into the base, causing the air guide hole at one end of the airflow valve to be retracted into the sealing component, effectively preventing the e-liquid in the oil tank from flowing into the air guide hole and then flowing out from the air inlet end of the airflow valve, thus preventing the e-liquid from leaking during the transportation of the electronic atomizer.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] Please see Figures 1-4 In this embodiment of the present invention, an airway sealing structure includes a base 1, a first cavity 11 inside the base 1, and an insertion hole 12 at the bottom of the base 1, the insertion hole 12 communicating with the first cavity 11. An airflow valve 2 is provided at the bottom of the base 1, the outlet end of the airflow valve 2 being inserted into the insertion hole 12 to allow air to flow through the inlet end at the bottom of the airflow valve 2 into the base 1. A sealing element 3 is provided in the first cavity 11, and the sealing element 3 has a first through hole 31. The outlet end of the airflow valve 2 is inserted into the lower end of the first through hole 31, and the outlet end of the airflow valve 2 is slidably oriented from the first through hole 31. The upper end of the through hole 31 extends out or retracts into the first through hole 31. At least one air guide hole 21 is provided at the air outlet end of the air flow valve 2. When the air outlet end of the air flow valve 2 extends out from the upper end of the first through hole 31, air can flow in from the air inlet end of the air flow valve 2 and then flow out from the air guide hole 21. At this time, the air flow valve 2 can guide the air to flow to the upper end of the seal 3 from the bottom air inlet end. When the air outlet end of the air flow valve 2 retracts into the first through hole 31, the inner wall of the first through hole 31 blocks the air guide hole 21, causing the air flow valve 2 to be unable to guide the air to flow to the upper end of the seal 3.

[0033] The air passage sealing structure is equipped with a locking module to limit the depth of the air outlet end of the airflow valve 2 inserted into the first through hole 31, so that the air outlet end of the airflow valve 2 can only be inserted into the first through hole 31, causing the airflow valve 2 to be unable to guide air to the upper end of the seal 3. The locking module includes a locking member 41 and a first limiting member 42 located at the lower end of the airflow valve 2. The locking member 41 is located on the bottom surface of the base 1 near the insertion hole 12. When the upper end of the airflow valve 2 is inserted into the insertion hole 12 and continues to go deeper, the first limiting member 42 gradually approaches the locking member 41 until it abuts against the lower end of the locking member 41. The upper end of the locking member 41 abuts against the bottom surface of the base 1, thus limiting the insertion depth of the airflow valve 2. At this time, the air outlet end of the airflow valve 2 can only be inserted into the seal 3 and cannot extend out from the upper end of the first through hole 31. The air guide hole 21 is blocked in the first through hole 31, causing the airflow valve 2 to be unable to guide air to the upper end of the seal 3. Specifically, the dimensions of the first limiting member 42 and the locking member 41 are both larger than the diameter of the first through hole 31. When the airflow valve 2 is gradually inserted into the first through hole 31, the first limiting member 42 can abut against the lower opening of the first through hole 31 to limit the insertion depth of the airflow valve 2.

[0034] Among them, reference appendix Figure 2 and attached Figure 4 The arrows indicate the airflow direction when the airflow valve 2 extends to the upper end of the first through hole 31 and when the airflow valve 2 retracts into the sealing member 3. The locking member 41 is detachable. When the electronic atomizer with this airway sealing structure is ready for normal use after transportation, people can remove the locking member 41 to release the restriction on the depth of the airflow valve 2 inserted into the first through hole 31, so that the air outlet end of the airflow valve 2 can extend from the upper end of the first through hole 31. At this time, the airflow valve 2 can conduct air to other components of the electronic atomizer. For example, the airflow valve 2 can deliver air to the atomizing core assembly 7 to achieve conduction with atmospheric pressure, which can drive the smoke generated by the atomizing core assembly 7 to be delivered to the mouthpiece 61 of the electronic atomizer for people to inhale.

[0035] Specifically, when the upper end of the airflow valve 2 extends from the upper end of the first through hole 31, air can flow in through the air inlet at the bottom of the airflow valve 2, and then flow out through the air guide hole 21 after passing through the internal pipe of the airflow valve 2. That is, the air can flow to the upper end of the seal 3 under the guidance of the airflow valve 2. The connection between the seal 3 and the base 1 includes, but is not limited to, snap-fit ​​connection and threaded connection. For example, an inner ring (not shown in the figure) can be provided inside the first cavity 11, and an outer ring protrusion (not shown in the figure) is provided on the outer surface of the seal 3. The seal 3 is inserted into the first cavity 11 so that the outer ring protrusion (not shown in the figure) is locked in the inner ring (not shown in the figure) to achieve the effect of locking and fixing the seal 3. The air outlet of the airflow valve 2 with the air guide hole 21 is in transition fit with the first through hole 31, which is conducive to the insertion of the airflow valve 2, and at the same time can ensure a certain positioning accuracy and reduce the wear of the airflow valve 2 and the seal 3.

[0036] Further as Figures 1-4 As shown in this embodiment of the utility model, the locking module further includes a second limiting member 43 disposed on the outer surface of the airflow valve 2. When the airflow valve 2 is inserted into the socket 12, the second limiting member 43 is inserted into the socket 12 along with the airflow valve 2. The end of the second limiting member 43 near the socket 12 is locked in the inner opening of the socket 12. Specifically, the base 1 is injection molded. When the airflow valve 2 is inserted into the socket 12, the cross section of the surface of the airflow valve 2 with the second limiting member 43 is larger than the size of the socket 12. Therefore, when the part of the airflow valve 2 with the second limiting member 43 is inserted into the socket 12, there is a certain resistance. However, since the base 1 is a plastic part, when people push the airflow valve 2 toward the socket 12, the socket 12 undergoes elastic deformation, which can also insert the second limiting member 43 into the socket 12. At this time, the second limiting member 43 is locked in the inner opening of the socket, making it difficult for the airflow valve 2 to be pulled out of the socket 12. Specifically, the shape of the second limiting member 43 is not limited; it can be conical or convex. When the second limiting member 43 is conical, it reduces the resistance of the insertion hole 12 to the second limiting member 43, making it easier for people to push the second limiting member 43 into the insertion hole 12. The first limiting member 42 and the second limiting member 43 are integrally formed with the airflow valve 2, for example, by injection molding.

[0037] Further as Figures 1-2 As shown, in this embodiment of the present invention, the thickness of the locking member 41 is not less than the gap depth between the upper end of the airflow valve 2 and the upper end of the first through hole 31, so as to ensure that the air outlet end of the airflow valve 2 cannot extend from the upper end of the first through hole 31 under the restriction of the locking member 41.

[0038] Further as Figures 1-2 As shown, in this embodiment of the present invention, the fastener 41 is provided with a fitting portion 411, which is arc-shaped and used to fit the outer surface of the airflow valve 2. Specifically, in this embodiment, the airflow valve 2 has a columnar structure, and the fitting portion 411 is arc-shaped with a circumference of 3 / 4 of a full circle, so that the fitting portion 411 can be fastened to the outer surface of the airflow valve 2.

[0039] Further as Figures 2-3As shown in this embodiment of the invention, the airway sealing structure further includes a sealing groove 51 formed on the top of the sealing member 3, an oil-absorbing cotton 52 for absorbing e-liquid, a bracket 53, and a sealing sleeve 54 set on the top of the bracket 53. The oil-absorbing cotton 52 is placed in the sealing groove 51 and has a second through hole 521 that connects to the first through hole 31. The bracket 53 extends downward and has an insertion part 531 for snapping onto the inner wall of the sealing groove 51. The oil-absorbing cotton 52 is covered inside the insertion part 531. The top of the bracket 53 has a third through hole 532 that connects to the second through hole. 521, the diameter of the third through hole 532 is smaller than the diameter of the second through hole 521, and the lower end of the second through hole 521 abuts against the bottom surface of the sealing groove 51, so that the second through hole 521 forms a chamber 522. When the air outlet end of the air flow valve 2 with the air guide hole 21 extends out from the first through hole 31, air can flow in from the air inlet end at the bottom of the air flow valve 2 and then flow out from the air guide hole 21 at the air outlet end of the air flow valve 2 into the chamber 522 through the pipe inside the air flow valve 2. The sealing sleeve 54 is snapped to the top of the bracket 53. The sealing sleeve 54 has a fourth through hole 541, which connects to the third through hole 532.

[0040] Specifically, the insertion part 531 has an outwardly protruding outer edge 5311, and the inner wall of the sealing groove 51 has a corresponding inwardly recessed first groove 511. When the insertion part 531 is inserted into the sealing groove 51, the outer edge 5311 of the insertion part 531 is just locked in the first groove 511 of the sealing groove 51, thereby achieving a snap-fit ​​connection between the insertion part 531 and the sealing groove 51. A stepped hole 533, wider at the top and narrower at the bottom, is provided on the top of the bracket 53. This "stepped hole 533" can be understood as an upper inner hole with a larger inner diameter and a lower inner hole with a smaller inner diameter. The stepped hole 533 connects to the third through hole 532. The outer edge 5311 of the sealing sleeve 54 extends downwards and then protrudes inwards to form the inner edge 542. A second groove 534 is formed by the inward indentation of the outer surface near the top of the bracket 53. The sealing sleeve 54 is fitted onto the top of the bracket 53, causing the inner edge 542 to engage with the second groove 534, thus achieving a snap-fit ​​connection between the sealing sleeve 54 and the bracket 53. Furthermore, the inner edge of the sealing sleeve 54, i.e., the edge of the fourth through hole 541, extends downwards to form a retaining edge 543. When the sealing sleeve 54 is fitted onto the top of the bracket 53... When the device is in place, the retaining edge 543 is inserted into the upper inner hole of the stepped hole 533. On the one hand, the retaining edge 543, combined with the inner edge 542, can be more firmly secured to the top of the bracket 53. On the other hand, the sealing sleeve 54 is made of silicone, which can provide a seal for the components subsequently inserted into the stepped hole 533. For example, when the atomizing core assembly 7 in the electronic atomizer, which is used to heat e-liquid to generate vapor, is inserted into the stepped hole 533, the air in the chamber 522 can flow in from the bottom of the atomizing core assembly 7 and then flow into the tube inside the atomizing core assembly 7 used to heat e-liquid to generate vapor. Subsequently, the vapor flows out from the outlet at the top of the atomizing core assembly 7. The retaining edge 543 of the sealing sleeve 54 can provide an effective seal at the connection between the atomizing core assembly 7 and the bracket 53.

[0041] Further as Figure 1 As shown in the embodiment of this utility model, the sealing element 3, the locking element 41, and the sealing sleeve 54 are all made of silicone. Specifically, the above-mentioned components can be manufactured by injection molding.

[0042] Further as Figures 1-4 As shown in the embodiment of this utility model, an electronic atomizer includes the above-mentioned airway sealing structure.

[0043] Further as Figures 1-3As shown, in this embodiment of the invention, the electronic atomizer further includes an oil tank 6 and an atomizing core assembly 7. The upper end of the oil tank 6 is provided with a mouthpiece 61 for inhalation. The upper end of the atomizing core assembly 7 has an outlet for vapor discharge that connects to the mouthpiece 61. The lower end of the oil tank 6 has a second cavity 62. The lower end of the oil tank 6 is mounted on the top of a sealing sleeve 54. The atomizing core assembly 7 is disposed within the second cavity 62. One end of the atomizing core assembly 7 passes through a fourth through hole 541 and is inserted into a third through hole 532. The other end of the atomizing core assembly 7 is connected to the mouthpiece 61, thus sealing the upper end of the oil tank 6. Specifically, the oil tank 6 is snap-fitted to the upper end of a bracket 53. The lower end of the atomizing core assembly 7 passes through the fourth through hole 541 and is inserted into the lower inner hole of a stepped hole 533, thus sealing the bottom of the second cavity 62 for storing e-liquid. The connection between the atomizing core assembly 7 and the mouthpiece 61 includes, but is not limited to, a snap-fit ​​connection. Since the sealing sleeve 54 effectively enhances the sealing performance at the connection between the atomizing core assembly 7 and the bracket 53, it can reduce the leakage of e-liquid from the connection between the atomizing core assembly 7 and the bracket 53 into the chamber 522. Furthermore, the absorbent cotton 52 in the chamber 522 can also absorb the e-liquid, further preventing e-liquid leakage.

[0044] The electronic atomizer features an airway sealing structure. During transportation, the locking element 41 is installed between the first limiting element 42 of the airflow valve 2 and the bottom surface of the base 1. This restricts the depth to which the airflow valve 2 can be inserted into the base 1, causing the air guide hole 21 at the upper end of the airflow valve 2 to be retracted within the sealing element 3. This effectively prevents e-liquid in the oil tank 6 from flowing into the air guide hole 21 and then out of the air inlet of the airflow valve 2, thus preventing e-liquid leakage during transportation. When needed, the locking element 14 is pulled out, and the airflow valve 2 is pressed slightly against the base 1, causing the air guide hole 21 to extend out of the first through hole 31 and release the seal, enabling air pressure communication with the atomizing core assembly 7. The airflow valve 2 can then transmit air to the atomizing core assembly 7's vapor-generating conduit, allowing for normal smoking.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
