Description

Technical Field

[0001] This utility model discloses an ignition device with an electromagnetic deflection switch, which relates to the field of electromagnetic switch technology. Background Technology

[0002] The core working mechanism of e-cigarettes revolves around the perforated design of the stainless steel tube: e-liquid permeates through pre-designed holes in the tube wall into the coil's oil reservoir, then is transported to the heating coil area via capillary action of the oil-guiding cotton, and finally atomized by the high temperature of the heating coil when energized. This process seems simple, but significant problems have been exposed in practical applications due to structural design flaws.

[0003] The chain reaction of malfunctions caused by e-liquid leakage is particularly prominent. Due to insufficient precision in the fit between the stainless steel tube's central hole and the e-liquid reservoir, e-liquid will continuously and slowly seep out through the gaps under the combined effects of gravity and osmotic pressure. The leaking e-liquid not only forms a pool of liquid in the airway, obstructing vapor flow and drastically reducing flavor, but more seriously, the liquid may seep into the device's internal circuitry. When the e-liquid comes into contact with the switching components or sensors, it can easily cause a short circuit or false triggering, causing the e-cigarette to automatically start when not in use, wasting e-liquid and posing a safety hazard of battery overheating.

[0004] The problem of low wicking efficiency directly impacts production and user experience. An unreasonable material density and fiber structure design of the wicking cotton causes the e-liquid to transfer from the reservoir cotton to the heating coil to lag behind the vaporization consumption. This necessitates an additional "pre-lubrication" process during product assembly—manually injecting e-liquid into the wicking cotton to ensure optimal atomization during initial use. This not only prolongs the production cycle and increases labor costs but may also lead to uneven lubrication, causing localized dry burning and a burnt taste, severely affecting the user experience.

[0005] These technical defects not only restrict the stability of product performance, but also become a major obstacle to the industry's large-scale production and the improvement of safety standards. Utility Model Content

[0006] This utility model addresses the problems of the prior art by providing an ignition device with an electromagnetic deflection switch. The technical solution adopted is as follows:

[0007] In a first aspect, an ignition device with an electromagnetic deflection switch includes: an oil cup assembly 1, an electromagnet 2, a battery 3, and a main board 4.

[0008] The oil cup assembly 1 includes an oil storage tank 5 and a deflection switch 6. The oil storage tank 5 is magnetically attracted to the electromagnet 2 through the deflection switch 6.

[0009] The battery 3 is connected to the main board 4 and the electromagnet 2 respectively; the main board 4 controls the battery 3 to conduct to the electromagnet 2, and the electromagnet 2 generates a magnetic field when energized, which is electromagnetically coordinated with the deflection switch 6.

[0010] In some implementations, the oil storage tank 5 includes an oil cup 8, a silica gel 9 under the oil cup, and an atomizing core 10;

[0011] The atomizing core 10 is located inside the oil cup 8. One end of the atomizing core 10 is connected to the silicone 9 under the oil cup, and the other end is connected to the outside, forming an air passage.

[0012] In some implementations, the atomizing core 10 includes a stainless steel tube 11 and a magnetic switch 12;

[0013] The stainless steel pipe 11 is connected and cooperates with the magnetic switch 12. The magnetic switch 12 drives the stainless steel pipe 11 to rotate, opening the oil storage tank 5.

[0014] In some implementations, the stainless steel tube 11 is provided with a heating wire support 13, an inner cotton 14, and a heating wire 15.

[0015] The heating wire 15 is surrounded by an inner cotton padding 14;

[0017] In some implementations, the heating wire support 13 is provided with an oil inlet hole 16, and the heating wire 15 is connected to the oil cup 8 through the oil inlet hole 16.

[0018] One or more embodiments of this utility model can bring at least the following beneficial effects:

[0019] The device operates based on the synergistic effect of electromagnetic induction and mechanical linkage, offering significant advantages over traditional technologies.

[0020] Intelligent controllability: By controlling the on / off state of the electromagnet 2 through the motherboard 4, the oil storage tank 5 can be automatically opened during suction and automatically closed when stopped, without manual operation, thus solving the problem of slow response of traditional mechanical switches.

[0021] Sealing reliability: The non-contact magnetic field transmission (the electromagnet 2 and the deflection switch 6 have no physical contact) is adopted, which avoids the sealing failure caused by wear in the contact transmission. Combined with the active closing design of the oil inlet 16, the leakage prevention capability of the oil storage tank 5 is greatly improved.

[0022] Highly efficient oil conduction: The oil inlet 16 is only opened during inhalation, and the e-liquid can directly seep into the inner cotton 14 through the oil inlet 16 without the need for pre-lubrication of the coil, which solves the problems of slow oil conduction and cumbersome assembly process in traditional technology.

[0023] In summary, this device achieves a precise balance between e-liquid atomization and leakage prevention through the dynamic control of the electromagnetic deflection switch 6. Its working principle not only reflects the application of electromagnetic technology in intelligent control, but also solves the technical problems of traditional electronic cigarettes through structural design optimization.

The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Figure 1 A schematic diagram of an ignition device with an electromagnetic deflection switch is shown, as follows. Figure 1 As shown, the ignition device with an electromagnetic deflection switch provided in this embodiment realizes intelligent opening and closing of the oil reservoir based on electromagnetic control technology. The core components include an oil cup assembly 1, an electromagnet 2, a battery 3, and a main board 4. Each component forms a closed-loop system through mechanical cooperation and circuit connection. The specific structure and function are as follows:

[0032] Oil cup assembly 1, as the core execution unit of the device, includes an oil storage tank 5, a deflection switch 6, and an atomizing structure, wherein:

[0033] Oil storage chamber 5: It is a sealed cavity formed by the oil cup 8, the silicone 9 under the oil cup and the atomizing core 10 through a sealed assembly. It is used to store e-liquid. Its sealing performance directly affects the anti-leakage effect.

[0034] Deflection switch 6: It has a built-in permanent magnet and can rotate around a fixed axis. It is both the actuator of the mechanical switch and the response component of electromagnetic induction. It achieves action switching by interacting with the magnetic field of electromagnet 2.

[0035] Atomizing core 10: Composed of a stainless steel tube 11, a heating wire support 13, inner cotton 14, and a heating wire 15. The stainless steel tube 11 serves as the structural carrier, internally fixing the heating wire support 13; the heating wire support 13 has an oil inlet hole 16, which is the key channel for e-liquid to enter the atomization area; the inner cotton 14 wraps around the heating wire 15, serving both as an oil guide and heat insulation function; the heating wire 15 is a resistive element, which generates high temperature after being energized to achieve e-liquid atomization.

[0036] Airway: Formed by the oil cup 8, atomizing core 10 and the central through hole of the silicone 9 under the oil cup, it is the flow path of the vapor after atomization.

[0037] Electromagnet 2: As a magnetic field generating component, it has no magnetism when not energized, but generates a controllable magnetic field when energized. The strength and direction of its magnetic field are determined by the input current. It drives mechanical action by interacting with the magnetic poles of the permanent magnet built into the deflection switch 6 (like poles repel and unlike poles attract).

[0038] Battery 3: Provides DC power and is connected to the main board 4 and electromagnet 2 in a circuit. The on / off state of its output current is controlled by the main board 4.

[0039] Mainboard 4: As the control center, it integrates sensors and control chips, which can sense the user's suction action (such as changes in air pressure or button signals), and trigger the battery 3 to supply power to or cut off the electromagnet 2 based on the sensing results.

[0040] Example 2:

[0041] Based on Example 1, the workflow of user suction when using this new device (opening of oil storage tank 5 and atomization process) is as follows:

[0042] When the user performs an inhalation operation, the device completes its work according to the logic chain of "signal triggering → circuit response → magnetic field drive → mechanical action → e-liquid atomization". The specific steps are as follows:

[0043] First, signal triggering and circuit startup.

[0044] When the user inhales, the air pressure inside the airway changes. The pressure sensor integrated into the mainboard 4 detects the pressure signal, or a trigger command is generated through user operation (such as pressing a button). After receiving the signal, the mainboard 4 immediately sends a power supply command to the battery 3. The battery 3 outputs DC current to the electromagnet 2 through wires, forming a power circuit.

[0045] Next, the magnetic field generation and deflection switch 6 will be activated.

[0046] When electromagnet 2 is energized, its coil generates a strong magnetic field, and the magnetic poles of this magnetic field are the same as the magnetic poles of the permanent magnet built into deflection switch 6 (e.g., both are N poles). According to the electromagnetic principle of "like poles repel each other," deflection switch 6 experiences an outward repulsive force and rotates around a fixed axis (the rotation angle is usually 30°-60°, depending on the structural design). This rotation directly drives the mechanical linkage structure, causing the oil inlet 16 on the heating wire bracket 13 to switch from the "closed state" to the "fully open state."

[0047] Next step: e-liquid delivery and atomization

[0048] After the oil inlet 16 is opened, the e-liquid in the oil storage tank 5 seeps into the inner cotton 14 of the atomizer core 10 under the influence of gravity and capillary action. The fibrous structure of the inner cotton 14 quickly absorbs and conducts the e-liquid to the outer heating wire 15. At this time, the main board 4 simultaneously supplies power to the heating wire 15 (in some designs, the heating wire 15 and the electromagnet 2 share the same power supply circuit, which is controlled synchronously by the main board 4). The heating wire 15 heats up rapidly due to the resistance effect (usually reaching 200-300℃), heating the e-liquid in contact to an atomized state.

[0049] Finally, smoke output

[0050] The atomized smoke is expelled outward through the airway formed by the atomizing core 10 and the silicone 9 under the oil cup under the negative pressure generated by the user's inhalation, and is finally inhaled by the user, completing one inhalation cycle.

[0051] Example 3:

[0052] Based on Embodiment 1 or 2, the workflow when the user stops pumping using this new device (closing of oil storage tank 5 and leakage prevention process);

[0053] When the user stops suction, the device completes the state transition according to the logic chain of "signal interruption → circuit shutdown → magnetic field disappearance → switch reset → sealing and leak prevention". The specific steps are as follows:

[0054] First, signal interruption and circuit shutdown.

[0055] After the user stops inhaling, the air pressure in the airway returns to normal. The mainboard sensor 4 no longer detects a pressure signal and immediately cuts off the power supply circuit from battery 3 to electromagnet 2. Electromagnet 2 loses its current input due to the power outage, and the magnetic field it generated disappears instantly.

[0056] Next, the deflection switch 6 is reset and the oil inlet 16 is closed.

[0057] As the magnetic field of electromagnet 2 disappears, the repulsive force on deflection switch 6 is released. Driven by its own magnetism (or by the attraction between opposite poles with the preset magnetic components in the device), its built-in permanent magnet automatically rotates in the opposite direction around the axis, returning to its initial position. This reset action causes the mechanical structure to close the oil inlet 16 on the heating wire bracket 13, completely blocking the e-liquid channel between the oil reservoir 5 and the atomizing core 10.

[0058] Next, the sealing and leak-proof guarantee of oil storage tank 5.

[0059] After the oil inlet 16 is closed, the oil reservoir 5 returns to a sealed state, preventing e-liquid from leaking into the atomizer coil 10 or the airflow channel through the oil inlet 16. Simultaneously, the sealing assembly structure of the oil cup 8, atomizer coil 10, and silicone 9 under the oil cup further enhances the leak-proof effect. Even if the device is tilted or inverted, e-liquid will not seep into the circuit area through gaps, fundamentally avoiding the problem of "e-liquid leakage causing airflow blockage or device self-starting" in traditional technologies.

[0060] The device operates based on the synergistic effect of electromagnetic induction and mechanical linkage, offering significant advantages over traditional technologies.

[0061] Intelligent controllability: By controlling the on / off state of the electromagnet 2 through the motherboard 4, the oil storage tank 5 can be automatically opened during suction and automatically closed when stopped, without manual operation, thus solving the problem of slow response of traditional mechanical switches.

[0062] Sealing reliability: The non-contact magnetic field transmission (the electromagnet 2 and the deflection switch 6 have no physical contact) is adopted, which avoids the sealing failure caused by wear in the contact transmission. Combined with the active closing design of the oil inlet 16, the leakage prevention capability of the oil storage tank 5 is greatly improved.

[0063] Highly efficient oil conduction: The oil inlet 16 is only opened during inhalation, and the e-liquid can directly seep into the inner cotton 14 through the oil inlet 16 without the need for pre-lubrication of the coil, which solves the problems of slow oil conduction and cumbersome assembly process in traditional technology.

[0064] In summary, this device achieves a precise balance between e-liquid atomization and leakage prevention through the dynamic control of the electromagnetic deflection switch 6. Its working principle not only reflects the application of electromagnetic technology in intelligent control, but also solves the technical problems of traditional electronic cigarettes through structural design optimization.
