Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve sealing technology for electronic cigarettes, specifically to an electromagnetic valve sealing structure used between the main and auxiliary oil tanks of an electronic cigarette. Background Technology

[0002] In conventional large-capacity e-cigarettes, the e-liquid in the reservoir is in constant contact with the atomizer coil, and the coil's inlet hole is always immersed in e-liquid, ensuring that the e-liquid always flows into the wicking cotton inside the coil. When the ambient temperature rises, the viscosity of the e-liquid decreases, and its fluidity increases, causing a large amount of e-liquid to seep out of the atomizer coil, resulting in product leakage and causing inconvenience and distress to consumers.

[0003] In existing technologies, to address the aforementioned problems, e-cigarette e-liquid storage compartments are typically configured as a main compartment and a secondary compartment. The main compartment is larger and stores e-liquid, not directly supplying it to the atomizer coil; the secondary compartment is smaller and directly supplies e-liquid to the atomizer coil. This effectively solves the problem of atomizer coil leakage. Simultaneously, an e-liquid supply channel is provided between the main and secondary compartments, and a solenoid valve is installed within this channel to control the e-liquid supply. However, the existing supply channel and solenoid valve have poor sealing performance, causing inconvenience to users. To solve these problems, this invention provides a solenoid valve sealing structure for the main and secondary e-liquid compartments of an e-cigarette. Utility Model Content

A cylindrical sealing sleeve is installed at the open end of the electromagnetic valve housing, and the side wall of the cylindrical sealing sleeve has a thin-walled contraction section. By controlling the energization or de-energization of the control coil, the sealing head is controlled to seal or release the oil inlet. Simultaneously, the sealing outer ring at the open end of the cylindrical sealing sleeve can seal the connection between the open end of the electromagnetic valve housing and the outlet end of the extension tube, improving the sealing effect.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1: like Figures 1 to 8 As shown, this embodiment provides a solenoid valve sealing structure for the main and auxiliary oil compartments of an electronic cigarette, including a solenoid valve body that seals the oil distribution pipe 3. The solenoid valve body includes a magnet post 12 slidably mounted inside the solenoid valve housing 11. One end of the magnet post 12 is connected to the inner wall of the solenoid valve housing 11 via a spring 13. A coil 14 is wound around the outer side of the solenoid valve housing 11. A cylindrical sealing sleeve 2 is installed at the open end of the solenoid valve housing 11. The end of the magnet post 12 is attached to the inner bottom surface of the cylindrical sealing sleeve 2. A sealing head 21 is integrally provided on the outer bottom surface of the cylindrical sealing sleeve 2. A thin-walled contraction section 22 is provided on the side wall of the cylindrical sealing sleeve 2. A sealing outer ring 23 is integrally connected to the outer side of the open end of the cylindrical sealing sleeve 2. An outer eaves ring 111 is provided on the outer side of the open end of the solenoid valve housing 11. The outer eaves ring 111 is fitted into an annular groove opened inside the sealing outer ring 23. The oil inlet 31 of the oil distribution pipe 3 is connected to the main oil storage tank 4, and the oil outlet 32 ​​of the oil distribution pipe 3 is connected to the auxiliary oil storage tank 5. The side wall of the oil distribution pipe 3 is integrally connected to the extension pipe 33, and the open end of the solenoid valve housing 11 is connected to the outlet end of the extension pipe 33. The sealing outer ring 23 seals the connection between the open end of the solenoid valve housing 11 and the outlet end of the extension pipe 33. When the coil 14 is not energized, under the elastic force of the spring 13, the sealing head 21 seals the oil inlet 31 or the oil outlet 32. When the coil 14 is energized, the coil generates an electromagnetic field. The directions of the N and S poles of the electromagnetic field are exactly opposite to the directions of the N and S poles of the magnet 12. Under the action of magnetic attraction, the magnet 12 overcomes the pushing force of the spring 13 and moves backward. The sealing head 21 slides into the extension pipe 33, releasing the oil inlet 31 or the oil outlet 32.

[0031] In this embodiment, a cylindrical sealing sleeve 2 is installed at the open end of the solenoid valve housing 11, and the side wall of the cylindrical sealing sleeve 2 is provided with a thin-walled contraction section 22; by controlling the coil 14 to be energized or de-energized, the sealing column head 21 is controlled to seal or release the oil inlet 31; at the same time, the sealing outer ring 23 provided at the open end of the cylindrical sealing sleeve 2 can seal the connection between the open end of the solenoid valve housing 11 and the outlet end of the extension tube 33, thereby improving the sealing effect and making it convenient and practical. Furthermore, the solenoid valve housing 11 is provided with a flange 112, which is fastened to the positioning post 51 integrally provided on the outside of the auxiliary oil storage tank 5 by screws; when the screws are tightened to fasten the flange 112 and the positioning post 51, the opening end of the solenoid valve housing 11 and the outlet end of the extension tube 33 are clamped to seal the outer ring 23, ensuring a stable connection and good sealing performance.

[0032] Furthermore, the upper end of the auxiliary oil storage tank 5 is provided with an end cap 52 that covers the bottom opening of the main oil storage tank 4. The end cap 52 is fixed to the bottom opening of the main oil storage tank 4 by snap-fit ​​and is provided with a sealing ring to ensure good sealing. The oil distribution pipe 3, the auxiliary oil storage tank 5, and the end cap 52 are integrally formed. The oil inlet 31 of the oil distribution pipe 3 is connected to the auxiliary oil storage tank 5, and the oil outlet 32 ​​of the oil distribution pipe 3 is connected to the end cap 52, so that the oil distribution pipe 3 connects the main oil storage tank 4 and the auxiliary oil storage tank 5.

[0033] Furthermore, the sealing head 21 has an integrally formed sealing protrusion 211 on its end face, a first annular sealing rib 212 on the edge of the end face of the sealing head 21, and a second annular sealing rib 213 on the edge of the end face of the sealing protrusion 211; a protrusion groove 214 is coaxially formed on the inner side of the inlet wall of the oil inlet 31 and the inner side of the inlet wall of the oil outlet 32; when the sealing head 21 seals the oil inlet 31 or the oil outlet 32, the sealing protrusion 211 seals and matches within the protrusion groove 214. By matching the sealing protrusion 211 within the protrusion groove 214, and simultaneously providing the first annular sealing rib 212 and the second annular sealing rib 213, the sealing effect of the oil inlet 31 or the oil outlet 32 ​​is improved.

The third annular sealing rib 231 seals the outlet end face of the extension tube 33. By setting the third annular sealing rib 231, the sealing effect is improved.

[0035] Example 3: like Figures 7 to 8 , Figures 12 to 13 As shown, while retaining all the technologies in Specific Embodiment 1, an inner annular groove 331 is coaxially formed on the inner wall of the outlet end of the extension tube 33. The sealing outer ring 23 is fitted and installed within the inner annular groove 331, and a fourth annular sealing rib 232 is integrally provided coaxially on the outer side of the sealing outer ring 23. By fitting the sealing outer ring 23 within the inner annular groove 331 and providing the fourth annular sealing rib 232, the sealing effect is improved.
