Description

Technical Field

[0001] This application relates to the field of electronic atomizers, and more particularly to a bottom air passage sealing structure for an electronic atomizer. Background Technology

[0002] An electronic cigarette typically consists of a housing, e-liquid box, vapor chamber, atomizer, and battery. It works by heating e-liquid with a heater, which vaporizes the e-liquid to produce vapor. Users inhale this vapor to obtain nicotine or other chemicals without burning tobacco, thus serving as a tobacco substitute. Furthermore, different flavorings can be added to the e-liquid to enhance the user experience.

[0003] During inhalation, to ensure smooth operation, both ends of the smoke duct are usually open. To reduce leakage of e-liquid from the e-liquid box to the outside of the casing during storage or transportation, air vents need to be made on the casing and sealed with plugs. When the user inhales, the plugs inside the air vents need to be removed so that air from outside the casing can enter the casing through the air vents, which is beneficial for widespread application.

[0004] However, in practical applications, because the plug is located on the shell and the end of the flue inside the shell is open, during storage and transportation, the e-liquid in the e-liquid box will flow into the flue. After the e-liquid reaches the flue, there may be some e-liquid flowing along the flue into the gaps inside the shell, which will contaminate the inside of the shell and also cause some loss of the e-liquid in the e-liquid box. There is room for improvement. Utility Model Content

[0005] In order to reduce the amount of e-liquid leaking out during storage or transportation, this application provides a bottom airway sealing structure for an electronic atomizer.

[0006] The bottom air passage sealing structure of the electronic atomizer provided in this application adopts the following technical solution: A bottom air passage sealing structure for an electronic atomizer includes a housing and a flue, an atomizing component, and a sealing component sequentially disposed on the housing. The housing has an insertion hole and a flow hole, the flow hole for allowing air to enter the interior of the housing, the insertion hole communicating with the flue, and the sealing component slidably disposed within the insertion hole. When a user applies external force to the sealing component to drive it to move along the insertion hole toward the flue until the sealing component abuts against the flue, the end of the flue abutting against the sealing component is in a closed state.

[0007] By adopting the above technical solution, and by setting a sliding sealing component on the shell, when the user applies external force to the sealing component, the sealing component comes into contact with the flue, thereby achieving the purpose of sealing the flue. During storage and transportation, this effectively solves the problem of e-liquid flowing into the gaps inside the shell along the flue, reducing e-liquid outflow, reducing pollution inside the shell, and reducing e-liquid loss. At the same time, when the user uses the device, they only need to apply a reverse force to the sealing component to separate it from the flue, thereby allowing air to enter the flue through the flow holes. This provides a feasible way to maintain the cleanliness inside the electronic atomizer and to ensure proper use of e-liquid.

[0008] Preferably, the sealing assembly includes a sealing rod and a silicone plug, the sealing rod being slidably disposed within the insertion hole and extending outward from the housing, and the silicone plug being disposed at the end of the sealing rod located inside the housing.

[0009] By adopting the above technical solution, the sealing component adopts a combination of a sealing rod and a silicone plug. The sealing rod is easy for the user to push and slide in the socket under external force to achieve the sealing operation of the flue. The silicone plug has good sealing and elasticity, and can fit tightly with the flue to further enhance the sealing effect, thereby more effectively reducing the leakage of e-liquid. At the same time, the elastic material of the silicone plug can also buffer external force to a certain extent and protect the connection between the flue and the sealing component.

[0010] Preferably, the silicone plug has a through hole, and the sealing rod passes through the through hole. When the user pulls the sealing rod along the shell, and applies a pulling force to the sealing rod after the silicone plug abuts against the shell, the sealing rod will separate from the through hole.

[0011] By adopting the above technical solution, the design of the through hole on the silicone plug and the sealing rod being separable allows the sealing rod to separate from the silicone plug when the user pulls the sealing rod and the silicone plug comes into contact with the shell and continues to apply force. This allows the sealing rod to separate along the shell, thus meeting the user's inhalation needs. The operation is simple and flexible.

[0012] Preferably, a locking platform is provided inside the through hole, and a flange is provided on the sealing rod, with the locking platform engaging with the flange.

[0013] By adopting the above technical solution, the interlocking action between the inner locking platform and the flange on the sealing rod can stabilize the relative position of the sealing rod and the silicone plug when the silicone plug is used to seal the flue. This prevents the sealing rod from separating from the silicone plug due to vibration or other factors during transportation. It also reduces the probability that the sealing rod will separate from the silicone plug before the silicone plug is completely separated from the flue when the user pulls the sealing rod, due to instability at the connection between the sealing rod and the silicone plug.

[0014] Preferably, the silicone plug has a guide opening at the end opposite to the end that abuts against the flue, and a guide portion is provided on the flange.

[0015] By adopting the above technical solution, when the sealing rod needs to be inserted into the through hole again, the guide rod can be quickly inserted into the transfer hole through the cooperation of the guide port and the guide part, so that the flange and the clamping platform can be quickly engaged.

[0016] Preferably, a limiting part is provided on the housing near the insertion hole, the limiting part being used to limit the maximum distance the silicone plug can move away from the flue.

[0017] By adopting the above technical solution, the limiting part provided on the housing near the insertion hole can limit the extreme distance of the silicone plug when it moves away from the flue. When the user pulls the sealing rod, so that the silicone plug and the sealing rod move synchronously until the flue is opened, the silicone plug is prevented from being pulled out excessively, so as to facilitate the reuse of the silicone plug.

[0018] Preferably, the end of the sealing rod located outside the housing is provided with a pulling part.

[0019] By adopting the above technical solution, the pull-in part located at one end of the sealing rod outside the housing increases the force point for the user to pull the sealing rod, making the pulling operation more effortless and convenient, and improving the user experience.

[0020] Preferably, the sealing rod is made of copper.

[0021] By adopting the above technical solution, the sealing rod is made of copper. Copper has good strength and wear resistance, which can ensure that the sealing rod is not easily damaged during repeated sliding operations, extending the service life of the sealing rod, thereby ensuring the long-term effective use of the entire bottom airway sealing structure. At the same time, copper also has a certain degree of stability, is not prone to chemical reaction with other components in the electronic atomizer, and is conducive to improving the overall appearance quality.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a sliding sealing component on the housing, when the user applies external force to the sealing component, the sealing component abuts against the flue, thereby achieving the purpose of sealing the flue. When the user uses it, he only needs to apply a reverse force to the sealing component to separate the sealing component from the flue, so that air can enter the flue through the flow hole. This provides a feasible way to keep the inside of the electronic atomizer clean and to use the e-liquid properly. 2. When the user pulls the sealing rod, after the silicone plug comes into contact with the housing and force is applied, the sealing rod can separate from the silicone plug, thus allowing the sealing rod to separate along the housing, making the operation simple; 3. When it is necessary to re-insert the sealing rod into the through hole, the guide rod can be quickly inserted into the transfer hole through the cooperation of the guide port and the guide part, so that the flange and the clamping platform can be quickly engaged.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a bottom air passage sealing structure for an electronic atomizer. (Refer to...) Figures 1-5 A bottom air passage sealing structure for an electronic atomizer includes a housing 1 and a flue 2, an atomizing component 3, and a sealing component 4 sequentially disposed on the housing 1. The housing 1 is hollow, forming a cavity 14 for installing the flue 2, the atomizing component 3, and the sealing component 4. The housing 1 has an insertion hole 5 and a flow hole 6. The flow hole 6 is used to allow air to enter the interior of the housing 1. The insertion hole 5 is connected to the flue 2. The housing 1 also has an inlet 15, which is connected to the flue 2 after inhalation. The inlet 15 is used to directly contact the user's mouth. The sealing component 4 is slidably disposed in the insertion hole 5. When the user applies external force to the sealing component 4 to drive the sealing component 4 to move along the insertion hole 5 toward the flue 2 until the sealing component 4 abuts against the flue 2, the end of the flue 2 that abuts against the sealing component 4 is in a closed state.

[0031] Specifically, the atomizing component 3 includes an atomizing part 31, a cartridge 32, and a battery (not shown in the figure). The cartridge 32 stores e-liquid. The atomizing part 31 is installed in the flue 2. The cartridge 32 is installed inside the housing 1. The battery is installed on the housing 1 on one side of the cartridge 32. When the user uses the device, the battery supplies power to the atomizing part 31, which atomizes the e-liquid flowing from the cartridge 32 to the atomizing part 31, so that the user can inhale the atomized e-liquid through the inhalation port 15.

[0032] It should be noted that the atomizing component 3 is a conventional component of electronic atomizers, which works together to atomize e-liquid. This is existing technology, and its specific composition and working principle will not be elaborated on here.

[0033] Correspondingly, when it is necessary to disconnect the connection between the flue 2 and the sealing component 4, a reverse force is applied to the sealing component 4, which can separate the sealing component 4 from the sealing component 4, so that air can smoothly enter the cavity 14 along the flow hole 6 and enter the flue 2.

[0034] Reference Figure 3 , Figure 4 as well as Figure 5 The sealing assembly 4 includes a sealing rod 41 and a silicone plug 42. The sealing rod 41 is slidably disposed in the socket 5 and extends outward from the housing 1. The silicone plug 42 is disposed at the end of the sealing rod 41 located inside the housing 1.

[0035] Specifically, the soft and easily deformable properties of silicone material allow it to fit tightly with the flue 2, further enhancing the sealing effect and thus more effectively reducing the leakage of e-liquid. At the same time, the elastic material of the silicone plug 42 can also buffer external forces to a certain extent, protecting the connection between the flue 2 and the silicone plug 42.

[0036] Furthermore, the silicone plug 42 has a through hole 7, and the sealing rod 41 is inserted into the through hole 7. When the user pulls the sealing rod 41 along the housing 1, and continues to apply a pulling force to the sealing rod 41 after the silicone plug 42 comes into contact with the housing 1, the sealing rod 41 will separate from the through hole 7. Thus, when the user uses the device, the sealing rod 41 can be removed along the insertion hole 5 after it is separated from the silicone plug 42, without affecting the user's grip experience when holding the housing 1 due to the exposed sealing rod 41 on the housing 1.

[0037] Meanwhile, a retaining platform 8 is provided inside the through hole 7, and a flange 9 is provided on the sealing rod 41. The retaining platform 8 and the flange 9 engage with each other. The retaining platform 8 and the silicone plug 42 are integrally formed. The retaining platform 8 is formed by a circumferential protrusion from the inner wall of the through hole 7 (e.g., through injection molding), and the flange 9 is formed by a circumferential protrusion from the outer wall of the sealing rod 41 (e.g., through machine tool processing). The diameter enclosed by the retaining platform 8 is smaller than the diameter of the flange 9. Therefore, when the sealing rod 41 is inserted into the through hole 7, due to the soft and easily deformable nature of the silicone material, the sealing rod 41 and the flange 9 cooperate to drive the through hole 7 to expand until... The flange 9 engages with the locking platform 8, and then the silicone plug 42 quickly returns to its original position. Its function is that the engagement between the locking platform 8 inside the through hole 7 and the flange 9 on the sealing rod 41 can stabilize the relative position of the sealing rod 41 and the silicone plug 42 when the silicone plug 42 seals the flue 2. This prevents the sealing rod 41 from separating from the silicone plug 42 due to vibration or other factors during transportation. It also reduces the probability that the sealing rod 41 will separate from the silicone plug 42 before the silicone plug 42 is completely separated from the flue 2 due to instability at the connection between the sealing rod 41 and the silicone plug 42 when the user pulls the sealing rod 41.

[0038] Correspondingly, the silicone plug 42 has a guide opening 10 at the end opposite to the end that abuts against the flue 2, and a guide part 11 is provided on the flange 9. The guide opening 10 is tapered and is formed by the end face of the silicone plug 42 facing the sealing rod 41 and recessed into the locking platform 8. At the same time, the end of the guide part 11 facing the guide opening 10 is rounded. Therefore, when the sealing rod 41 needs to be inserted into the through hole 7 again, the guide opening 10 and the guide part 11 cooperate, and the guide opening 10 guides the rod to be quickly inserted into the transmission hole, so that the flange 9 and the locking platform 8 can be quickly locked together.

[0039] Reference Figures 3-5 A limiting part 12 is provided on the housing 1 near the insertion hole 5. The limiting part 12 is used to limit the extreme distance when the silicone plug 42 moves away from the flue 2. The limiting part 12 is located inside the housing 1 and is formed by protruding from the bottom of the housing 1 toward the atomizing part 31. The limiting part 12 and the insertion hole 5 are on the same axis. The size of the limiting part 12 and the size tolerance of the silicone plug 42 are in clearance fit, so that the silicone plug 42 can slide smoothly along the limiting part 12.

[0040] Therefore, the limiting part 12 provided on the housing 1 near the insertion hole 5 can limit the maximum distance that the silicone plug 42 can move away from the flue 2. When the user pulls the sealing rod 41, the silicone plug 42 moves synchronously with the sealing rod 41 until the flue 2 is opened, preventing the silicone plug 42 from being pulled out excessively, so as to facilitate the reuse of the silicone plug 42.

[0041] Meanwhile, a pulling part 13 is provided at one end of the sealing rod 41 located outside the housing 1. The pulling part 13 is integrally formed with the sealing rod 41. The size of the pulling part 13 is larger than that of the sealing rod 41, which increases the force point for the user to pull the sealing rod 41, making the pulling operation more effortless and convenient, and improving the user experience.

[0042] Correspondingly, the sealing rod 41 is made of copper. Copper has good strength and wear resistance, which can ensure that the sealing rod 41 is not easily damaged during repeated sliding operations, thus extending the service life of the sealing rod 41 and ensuring the long-term effective use of the entire bottom airway sealing structure. At the same time, copper also has a certain degree of stability, making it less likely to react chemically with other components in the electronic atomizer, and it is also conducive to improving the overall appearance quality.

[0043] The implementation principle of the bottom air passage sealing structure of an electronic atomizer according to this application embodiment is as follows: By setting a slidable sealing component 4 on the housing 1, when the user applies external force to the sealing component 4, the sealing component 4 abuts against the smoke passage 2, thereby achieving the purpose of sealing the smoke passage 2. During storage and transportation, this effectively solves the problem of e-liquid flowing into the internal gap of the housing 1 along the smoke passage 2, reducing the outflow of e-liquid, reducing the pollution inside the housing 1 and the loss of e-liquid; at the same time, when the user uses it, only a reverse force needs to be applied to the sealing component 4 to separate the sealing component 4 from the smoke passage 2, so that air can enter the smoke passage 2 through the flow hole 6, providing a feasible way to maintain the cleanliness inside the electronic atomizer and the proper use of e-liquid.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
