Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, specifically a low-power solenoid valve used in electronic cigarettes. Background Technology

[0002] As a crucial component in automation control, solenoid valves have broad prospects for technological development and application. With continuous technological advancements, solenoid valves, with their advantages of being lightweight, compact, and highly responsive, will play an increasingly important role in more fields, driving the development of industrial automation and intelligence.

[0003] As a substitute for traditional cigarettes, e-cigarettes can provide nicotine to alleviate withdrawal symptoms, simulate smoking behavior to satisfy psychological dependence, and avoid the harmful substances produced by tobacco combustion. As a transitional tool for quitting smoking, they are sought after by traditional smokers. The production of e-cigarettes requires the use of solenoid valves, but the solenoid valves in existing e-cigarettes have problems such as high power consumption, coil overheating, and high production costs. Utility Model Content

[0004] (a) Technical problems to be solved.

[0005] To address the shortcomings of existing technologies, this utility model provides a low-power solenoid valve for use in electronic cigarettes, solving the problems mentioned in the background art regarding high power consumption, coil overheating, and high production costs of solenoid valves in electronic cigarettes.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-power solenoid valve for use in electronic cigarettes, comprising a housing, a coil assembly, a movable iron core, a fixed iron core, a push rod, and a spring. The solenoid valve further comprises a magnet. The coil assembly, the fixed iron core, and the magnet have axial through holes. The fixed iron core is inserted into the axial through hole of the coil assembly. The magnet is magnetically connected to the bottom of the fixed iron core to enhance the force when opening the solenoid valve and to keep the solenoid valve open when power is off. The coil assembly is placed inside the housing and abuts against its bottom. The bottom of the housing has a through hole in the middle. The movable iron core is inserted into the through hole of the coil assembly and abuts against the fixed iron core. The push rod passes through the through holes in the housing, the magnet, and the fixed iron core and is fixedly connected to the movable iron core. The spring is sleeved on the movable iron core, with one end fixedly engaged by a groove at one end of the movable iron core and the other end abutting against the housing. Its elastic force is less than the magnetic force of the magnet, used to enhance the force when closing the solenoid valve.

[0008] Preferably, the coil assembly includes a spool and an enameled coil, the enameled coil being wound on the spool and electrically connected to the switch.

[0009] Preferably, the shell is cylindrical.

[0010] Preferably, the push rod is interference-fitted with the movable iron core.

[0011] (iii) Beneficial effects.

[0012] This utility model provides a low-power solenoid valve for use in electronic cigarettes, which has the following advantages compared to the solenoid valves used in traditional electronic cigarettes: 1. The addition of a magnet ensures that the solenoid valve remains open even when the power is off, and only reverse power is needed when the solenoid valve is closed, preventing the electromagnetic coil in the solenoid valve from overheating due to prolonged power supply; 2. The addition of a magnet ensures that the solenoid valve remains open even when the power is off, reducing the power consumption of the solenoid valve; 3. During installation, one end of the spring directly engages with a groove on one end of the movable iron core, reducing the number of retaining spring parts, lowering production costs, and simplifying the installation process.

[0017] 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.

[0018] Example 1

[0019] Please see Figure 1This utility model provides a low-power solenoid valve for use in electronic cigarettes, including a housing 1, a coil assembly 2, a movable iron core 3, a fixed iron core 4, a push rod 5, and a spring 7. The solenoid valve further includes a magnet 6. The coil assembly 2, the fixed iron core 4, and the magnet 6 are provided with axial through holes. The fixed iron core 4 is inserted into the axial through hole of the coil assembly 2. The magnet 6 is magnetically connected to the bottom of the fixed iron core 4 to enhance the force when opening the solenoid valve and to keep the solenoid valve open when power is off. The component 2 is placed inside the housing 1 and abuts against its bottom. The housing 1 has a through hole in the middle of its bottom. The movable iron core 3 is placed into the through hole of the coil assembly 2 and abuts against the fixed iron core. The push rod 5 passes through the through holes provided in the housing 1, magnet 6, and fixed iron core 4 and is fixedly connected to the movable iron core 3, preferably with an interference fit. The spring 7 is sleeved on the movable iron core 3. One end is fixedly engaged by a groove provided at one end of the movable iron core 3, and the other end is intermittently connected to the fixed iron core 4. Its elastic force is less than the magnetic force of the magnet 6 and is used to strengthen the force of closing the solenoid valve.
