Description

Technical Field

[0001] This utility model relates to the field of electromagnet technology, specifically to an electromagnet assembly and an electronic cigarette oil supply structure.

[0002] Background technology.

[0003] E-cigarettes, as a novel alternative to traditional tobacco, have seen widespread adoption in recent years. Their core structure typically includes an e-liquid tank, a mouthpiece, and an e-liquid channel connecting the two. This channel delivers e-liquid to the atomizing device for heating and vapor production for the user to inhale. However, existing e-cigarettes face several technical challenges in practical use. For example, when not in use, improper storage or impact can cause e-liquid leakage from the channel to the mouthpiece due to gravity or pressure changes. This not only wastes e-liquid but can also negatively impact the user experience and even damage the device's internal structure. Furthermore, during use, impacts and vibrations can cause the valve to open, allowing excessive e-liquid to flow into the atomizing chamber. This can result in an excessively strong vapor production and a less enjoyable experience when inhaling. Additionally, the fixed e-liquid supply system in most current e-cigarettes prevents flexible control of the channel's flow, further increasing the risk of leakage. E-liquid leakage can corrode electronic components inside e-cigarettes, such as the electromagnetic core, reducing the lifespan of the e-cigarette. Existing technologies also improve the corrosion resistance of electronic components, but the manufacturing cost is high. Utility Model Content

[0004] This invention provides an electromagnet assembly that can be used for sealing the oil passages in electronic cigarettes, effectively protecting the moving iron core, improving service life, and reducing costs.

[0005] An electromagnet assembly includes a frame with a current-carrying coil wound around its outer wall. The frame has an inner cavity containing an elastic element and a moving iron core. One end of the elastic element abuts against the bottom of the moving iron core, and the other end of the elastic element abuts against the bottom of the inner cavity. The moving iron core can move within the inner cavity. When the elastic element is in its normal state, it pushes the end of the moving iron core out of the inner cavity. A retractable rubber cap is provided on the top of the frame, sealing the upper part of the inner cavity. The top of the moving iron core is fixedly connected to the top of the rubber cap to achieve synchronous movement.

[0006] When energized, the electromagnet assembly compresses the moving iron core downwards, causing the elastic element to move and thus opening the circuit. When de-energized, the elastic element pushes the moving iron core upwards, thus sealing the circuit. A deformable cap on the frame seals the inner cavity outlet, effectively preventing e-liquid leakage and corrosion of the moving iron core. Therefore, the moving iron core can be made of magnetic material, eliminating the need for extensive anti-corrosion treatment and reducing costs. Simultaneously, the cap encloses the elastic element and moving iron core within the inner cavity, resulting in a robust electromagnet assembly structure that can be directly connected to the e-cigarette casing, simplifying subsequent e-cigarette installation and enhancing market competitiveness.

[0007] Furthermore, a reverse fastener is provided at the top of the frame. The side wall of the reverse fastener is recessed inward to form a tension groove. The lower end of the rubber cap is fastened to the tension groove to achieve a tight connection and seal the inner cavity outlet.

[0008] The cap is connected to the buckle by a snap-fit ​​mechanism, forming a detachable connection structure that facilitates installation and disassembly.

[0009] Furthermore, the cap includes a first crown and a second crown, the diameter of the first crown is smaller than that of the second crown, the diameter of the first crown is equivalent to the end diameter of the moving iron core to achieve fitting, and the second crown can be compressed and deformed.

[0010] By setting caps of different diameters, the first cap is connected to the moving iron core, improving the support force of the first cap to achieve support force and sealing during sealing. The second cap can be compressed and deformed, and can also be restored by the thrust of the elastic element, thus protecting the moving iron core while realizing the sealing and opening operations.

[0011] Furthermore, the moving iron core is a permanent magnet core, such as neodymium iron boron; the elastic element is a spring; the rubber cap is a silicone rubber cap; and the frame is a plastic shell.

[0012] Because of the protective cap for the moving iron core, this application does not require a fixed iron core. The moving iron core can be made of permanent magnet material directly, without the need for excessive anti-corrosion treatment, effectively reducing material costs. The silicone cap is food-grade, safe and hygienic, and can ensure safety even when in contact with e-cigarette oil, with significant anti-corrosion effect.

[0013] Furthermore, the top of the moving iron core is fixedly connected to the inner wall of the top of the rubber cap by means of snap-fit, plug-in, adhesive, or combination. The processing technology is simple, and the assembly is relatively easy. Adding adhesive can further improve the stability of the connection.

[0014] Furthermore, the frame is provided with connectors. The connectors are used to connect to the electronic cigarette housing, facilitating the subsequent installation of the electronic cigarette.

[0015] Furthermore, the connector is a connecting ear protruding from both sides of the frame, and the connecting ear is provided with a connecting hole. This structure can be connected to the electronic cigarette shell by using bolts or screws passing through the connecting holes, making installation and disassembly simple.

[0016] The device includes a mouthpiece housing with an interconnected oil inlet and an oil outlet. The oil inlet is located to the side of the oil outlet, and the connection between the oil inlet and the oil outlet is configured as an oil passage. The electromagnet assembly is fixedly installed in the oil passage. The top of the cap is aligned with the oil outlet, and the side wall of the cap faces the oil inlet. The moving iron core drives the cap to move up and down in the cavity within the oil passage to block or open the oil inlet and the oil outlet.

[0017] This electronic cigarette uses a side-supply mechanism, with the electromagnet assembly positioned in the oil passage connecting the inlet and outlet. This allows for selective blocking of either the inlet or outlet. The top of the cap is aligned with the outlet, allowing for either blocking by extending the top of the cap into the outlet or by using the side wall of the cap to abut against the inlet. Different control methods can be selected based on the specific situation, offering high flexibility.

[0018] The top of the cap can be inserted into the oil outlet to control the sealing of the oil outlet. When the coil is energized, the top of the cap moves downward with the moving iron core and retracts inward to open the oil passage. When the coil is de-energized, the elastic element pushes the moving iron core upward to reset, and the top of the cap extends upward to block the oil passage. The outer surface of the cap is tightly fitted with the inner wall of the oil outlet.

[0019] The oil passages can be opened, closed, and connected using the above structure and method, which is convenient to control, simple in structure, and has a good leak-proof effect.

[0020] Furthermore, the mouthpiece housing is provided with threaded holes, and the electromagnet assembly is fixed to the mouthpiece housing through threaded connectors.

[0021] Furthermore, the top of the cap can be inserted into the oil outlet to control the sealing of the oil outlet; the lower end of the cap is provided with a brim, and the mouthpiece housing is correspondingly provided with a rolled portion. When the electromagnet assembly is fixedly connected to the mouthpiece housing, the rolled portion presses against the brim. This further ensures the cap's sealing performance over the inner cavity.

[0022] The above-described solution of this utility model has at least the following beneficial effects: When energized, the electromagnet assembly compresses the moving iron core downwards, causing the spring to move and thus opening the circuit. When de-energized, the spring pushes the moving iron core upwards, thus sealing the circuit. A deformable cap on the frame seals the inner cavity outlet, effectively preventing e-liquid leakage and corrosion of the moving iron core. Therefore, the moving iron core can be made of permanent magnet material, eliminating the need for extensive anti-corrosion treatment and effectively reducing costs. Simultaneously, the cap encloses the elastic element and moving iron core within the inner cavity, resulting in a robust electromagnet assembly structure that can be directly connected to the e-cigarette casing, simplifying subsequent e-cigarette installation and enhancing market competitiveness.

[0023] This electronic cigarette uses a side-supply mechanism, with the electromagnet assembly positioned in the oil passage connecting the inlet and outlet. This allows for selective blocking of either the inlet or outlet. The top of the cap is aligned with the outlet, allowing for either blocking by extending the top of the cap into the outlet or by using the side wall of the cap to abut against the inlet. Different control methods can be selected based on the specific situation, offering high flexibility.

[0041] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. This utility model provides an electromagnet assembly, such as... Figure 1-2 As shown, the assembly includes a frame 1, a connector 2, a coil 3, a rubber cap 4, a moving iron core 5, and an elastic element 6. The coil 3 is wound around the outer wall of the frame 1. The bottom of the elastic element 6 abuts against the bottom of the inner cavity of the frame 1. The moving iron core 5 is placed on the upper end of the elastic element 6. The connector 2 is integrally formed on the upper side of the frame 1. The rubber cap 4 is sealed on the upper surface of the frame 1 and fixedly connected to the top of the moving iron core 5. The electromagnet assembly is fixed to the bottom of the mouthpiece housing 7 through the connector 2.

[0042] Specifically, the skeleton 1 has an overall cylindrical structure with an open top, such as... Figure 3 As shown, the inner cavity is a cylindrical through hole running vertically, and its inner diameter is adapted to the outer diameter of the moving iron core 5, ensuring that the moving iron core 5 can move smoothly back and forth in the inner cavity. Furthermore, the outer wall of the frame 1 is provided with an annular groove 13 in the middle, and its inner wall is provided with anti-slip texture.

[0043] Specifically, the coil 3 is made of copper enameled wire, which can generate a stable magnetic field when a direct current is applied. The coil 3 is wound into the annular groove 13 and forms a tight fit with the anti-slip texture of the inner wall of the annular groove 13, which effectively prevents the coil 3 from loosening or shifting during use, and achieves the function of limiting and fixing.

[0044] Specifically, the elastic element 6 is a cylindrical helical spring, which can be made of stainless steel, with an outer diameter approximately equal to the inner diameter of the frame 1. One end of the elastic element 6 abuts against the bottom of the moving iron core 5, and the other end directly contacts the bottom plane of the inner cavity of the frame 1. Through the precise fit between the outer diameter of the spring and the inner diameter of the cavity, it is ensured that the elastic element 6 always reciprocates stably along the axial direction during compression and reset, avoiding radial offset or skewing.

[0045] Specifically, the top of the frame 1 is integrally formed with a circular buckle 11. The side wall of the buckle 11 is recessed to form a tensioning groove 12, which is used to cooperate with the rubber cap 4 to seal the rubber cap 4 on the upper surface of the frame 1.

[0046] Specifically, the cap 4 is preferably made of food-grade oil-resistant silicone material. This material has excellent resistance to e-cigarette e-liquid and is not prone to swelling, aging or performance degradation with long-term contact. It can effectively block e-liquid penetration and prevent e-liquid from entering the inner cavity of the frame 1 and corroding the moving iron core 5 and the elastic element 6. It is also safe and effective.

[0047] Specifically, the cap 4 includes a first crown 41 and a second crown 42 formed in one piece, such as... Figure 4 As shown, the diameter of the first cap 41 is approximately the same as that of the moving iron core 5, which not only ensures precise fitting with the moving iron core 5 but also enhances the supporting force of the first cap 41, guaranteeing the supporting effect and sealing performance during sealing. The diameter of the second cap 42 is slightly larger than that of the first cap 41, and it can be compressed and deformed axially under pressure. The first cap 42 can be completely retracted into the second cap 42 to achieve control over the opening and closing of the oil circuit.

[0048] Furthermore, the moving iron core 5 is a permanent magnet with an overall cylindrical structure. Its top center is recessed inward to form a cylindrical groove 51, used for fixed connection with the rubber cap 4. An extension block 43 is provided on the inner side of the first cap 41, such as... Figure 5 As shown, when the first cap 41 is fitted onto the top of the moving iron core 5, the extension block 43 is inserted into the groove 51 on the top of the moving iron core 5 to achieve a fixed connection between the two. Furthermore, glue or hot melt glue can be added to make the connection between the extension block 43 and the groove 51 more stable and improve the continuous stability of the control.

[0049] Furthermore, the inner side of the bottom end of the second crown 42 is provided with an annular protrusion 45. The thickness of the annular protrusion 45 is precisely matched with the width of the tensioning groove 12. It is fastened into the tensioning groove 12 to achieve a tight connection, which can completely seal the inner cavity outlet and prevent e-liquid from seeping in.

[0050] Specifically, a connector 2 is provided at the bottom of the upper part of the frame 1 corresponding to the tensioning groove 12, such as... Figure 3 As shown, the connector 2 is a symmetrical connecting ear 21 protruding from both sides of the frame 1. It can be integrally injection molded with the frame 1, resulting in a stable and robust structure. Furthermore, the upper end face of the connector 2 directly serves as the bottom support surface of the tensioning groove 12, simplifying the overall structural design and providing stable support for the snap-fit ​​of the cap 4. Each connecting ear 21 has a through connecting hole 22, which can be precisely matched with the threaded hole 71 pre-set in the electronic cigarette housing by bolts or screws, achieving a stable connection between the electromagnet assembly and the mouthpiece housing 7, making assembly convenient.

[0051] This embodiment also provides an electronic cigarette oil supply structure, including a mouthpiece housing 7. Specifically, the mouthpiece housing 7 is integrally injection molded, such as... Figure 6 As shown, its interior has interconnected oil inlet 81, oil outlet 82 and oil passage 8, which together form a stable side oil supply channel; this side oil supply mode has the core advantages of stable oil supply, excellent leak prevention, high space utilization, flexible control and convenient assembly and maintenance, effectively improving the user experience and the overall practicality of the product.

[0052] Specifically, the oil inlet 81 of the mouthpiece housing 7 is located to the side of the oil outlet 82, with their axes perpendicularly distributed. The oil inlet 81 is connected to the main oil passage 8 via a transverse oil channel; the oil outlet 82 is located at the top of the mouthpiece housing 7 and is perpendicularly connected to the main oil passage 8. The connection between the oil inlet 81 and the oil outlet 82 forms a cylindrical receiving cavity 83, such as... Figure 7 As shown, this provides ample space for the reciprocating motion of the cap 4 and facilitates the flow of e-liquid.

[0053] Specifically, the mouthpiece housing 7 has threaded holes 71 on both sides corresponding to the connecting holes 22 of the connecting lugs 21, such as... Figure 8 As shown, the electromagnet assembly is fixedly installed on the bottom of the mouthpiece housing 7 by bolts passing through the connecting hole 22 of the connecting ear 21. After installation, the top of the rubber cap 4 is precisely aligned with the oil outlet 82, and the side wall of the rubber cap 4 is directly opposite the oil inlet 81, ensuring that the sealing or opening action can be accurately achieved during movement.

[0054] Specifically, the top of the first crown 41 of the cap 4 is a cylindrical structure, and its diameter precisely corresponds to the diameter of the oil outlet 82. Driven by the moving iron core 5, it can be smoothly inserted into the oil outlet 82 along the axis and fit tightly against the inner wall of the oil outlet 82, thereby improving the sealing and leak-proof effect.

[0055] Specifically, the lower outer side of the cap 4 is provided with a cap edge 44, and the bottom of the mouthpiece housing 7 is provided with a corresponding annular pressing edge 72. When the electromagnet assembly is fixedly connected to the mouthpiece housing 7, the pressing edge 72 presses against the cap edge 44, further enhancing the sealing of the connection between the two and preventing e-liquid from leaking from the connection.

[0056] Specifically, when coil 3 is energized, a magnetic field is generated inside coil 3 to attract the moving iron core 5. The moving iron core 5 overcomes the elastic force of the elastic element 6 and moves downward, compressing the elastic element 6 to store elastic potential energy. At the same time, it drives the rubber cap 4 to move downward synchronously, releasing the blockage of the oil outlet 82 and opening the oil passage 8. When coil 3 is de-energized, the magnetic field disappears, the elastic element 6 releases its elastic potential energy, pushing the moving iron core 5 to return to its original position. This causes the rubber cap 4 to move upward synchronously, with the top of the rubber cap 4 axially inserted into the oil outlet 82, tightly fitting against the inner wall of the oil outlet 82, blocking the oil passage 8, thus achieving a seal and preventing e-liquid leakage. At the same time, the rubber cap 4 effectively protects the moving iron core 5 and the elastic element 6 from the corrosion and influence of e-liquid, ensuring the stable and long-term operation of the electromagnet assembly, reducing the cost of anti-corrosion treatment of the moving iron core 5, increasing the service life of the electronic cigarette, and reducing the processing cost of the electronic cigarette.
