[0035] In one embodiment of this utility model, such as Figures 1-2 As shown, an electronic cigarette electromagnetic lock is provided, comprising:
[0036] The outer casing 10 has a receiving cavity 11.
[0037] Coil assembly 20, wherein the coil assembly 20 is disposed within the receiving cavity 11;
[0038] The coil assembly 20 is internally provided with a stationary iron core 30, a moving iron core 40, and a reset spring 50 for resetting the moving iron core 40.
[0039] A buffer pad is provided at the contact position between the stationary iron core 30 and the moving iron core 40;
[0040] A drive head 60 is provided at one end of the moving iron core 40 away from the stationary iron core 30, and the drive head 60 is elastic.
[0041] Specifically, the electronic cigarette electromagnetic lock of this utility model includes a housing 10, with a receiving cavity 11 inside the housing 10. A coil assembly 20 is disposed within the receiving cavity 11. The coil assembly 20 internally consists of a stationary iron core 30, a moving iron core 40, and a return spring 50. The return spring 50 functions to reset the moving iron core 40. A buffer pad is provided at the contact point between the stationary and moving iron cores 40 to reduce noise and wear generated during contact. An elastic drive head 60 is provided at the end of the moving iron core 40 furthest from the stationary iron core. This design aims to reduce noise generated during the start-up and shutdown of the electromagnet, thereby improving the user experience of the electronic cigarette. By internally configuring a stationary iron core, a moving iron core 40, and a return spring 50, the opening and closing functions of the electromagnetic lock are achieved. The buffer pad at the contact point between the stationary and moving iron cores 40 effectively reduces impact noise generated during contact. The elastic drive head 60 at the end of the moving iron core 40 furthest from the stationary iron core further absorbs impact energy and reduces noise.
[0042] In another embodiment of this utility model, such as Figures 1-2 As shown, the bottom of the receiving cavity 11 has a through hole for mounting the stationary iron core 30. Specifically, the bottom part of the receiving cavity 11 is designed to have a dedicated through hole for mounting the stationary iron core 30, thereby positioning the stationary iron core 30 and preventing the position of the stationary iron core 30 from shifting.
[0043] In another embodiment of this utility model, such as Figures 1-2 As shown, a first annular groove is also provided at the bottom of the receiving cavity 11. The first annular groove is located on the outer periphery of the through hole, and a washer for cushioning the stationary iron core 30 is provided inside the first annular groove. Specifically, a first annular groove is provided at the bottom of the receiving cavity 11. This first annular groove is located in the outer periphery of the through hole. In order to further enhance the stability of the structure and the cushioning effect, a washer for cushioning the stationary iron core 30 is specially provided inside the first annular groove. In this way, when the stationary iron core 30 is impacted by the moving iron core 40, it can cushion the impact force brought by the moving iron core 40, avoid direct collision between the stationary iron core 30 and the outer shell 10, and reduce noise.
[0044] In another embodiment of this utility model, such as Figures 1-2 As shown, the stationary iron core 30 and the moving iron core 40 are configured with a concave-convex structure. The stationary iron core 30 has a groove, and the moving iron core 40 has a boss. A buffer pad is provided on the bottom surface of the groove. Specifically, the stationary iron core 30 has a groove, while the moving iron core 40 has a boss. To further improve the buffering effect of the contact surface, a buffer pad is provided on the bottom surface of the groove, thereby reducing the noise generated when the stationary iron core 30 and the moving iron core 40 come into contact.
[0045] In another embodiment of this utility model, such as Figures 1-2 As shown, the coil assembly 20 includes a coil support and a coil winding wound around the outer periphery of the coil support;
[0046] When the stationary iron core 30 and the moving iron core 40 are attracted together, the top surface of the coil support contacts the bottom surface of the elastic drive head 60. Specifically, the coil assembly 20 includes a coil support and a coil winding wound around the outer periphery of the coil support; wherein, when the stationary iron core 30 and the moving iron core 40 are attracted together, the top surface of the coil support contacts the bottom surface of the elastic drive head 60, thereby reducing the noise generated when the moving iron core 40 contacts the coil support.
[0047] In another embodiment of this utility model, such as Figures 1-2 As shown, the coil support is hollow inside, and the hollow part has a stepped structure. One end of the return spring 50 abuts against the stepped structure, and the other end of the return spring 50 abuts against the moving iron core 40. Specifically, the coil support is designed to be hollow inside, and a stepped structure is provided in the hollow part. One end of the return spring 50 abuts against the stepped structure, while the other end of the return spring 50 abuts against the moving iron core 40. This can stably fix the return spring 50 and prevent it from falling off and causing malfunction.
[0048] In another embodiment of this utility model, such as Figures 1-2 As shown, the moving iron core 40 is provided with a receiving portion extending radially therefrom, which abuts against the return spring 50. Specifically, the moving iron core 40 is provided with a receiving portion extending radially therefrom, the diameter of which is larger than the diameter of the return spring 50, thereby effectively receiving the return spring 50.
[0049] In another embodiment of this utility model, such as Figures 1-2 As shown, the drive head 60 has an elastically deformable opening that covers the receiving portion. Specifically, the drive head 60 has an elastically deformable opening that can cover the receiving portion, preventing the rigid part from contacting the coil support and generating noise.
[0050] In another embodiment of this utility model, such as Figures 1-2 As shown, the opening avoids the engagement position between the return spring 50 and the receiving part. Specifically, this ensures that no interference occurs between the return spring 50 and the receiving part during operation, thereby improving the stability and reliability of the overall structure.
[0051] In another embodiment of this utility model, such as Figures 1-2As shown, the side wall of the stationary iron core 30 is provided with a second annular groove 31, and a sealing ring 70 is provided in the second annular groove 31 to prevent the stationary iron core 30 from sliding. Specifically, the sealing ring 70 can ensure that the stationary iron core 30 can remain in a predetermined position when subjected to external force, and will not undergo unnecessary displacement, effectively preventing the stationary iron core 30 from sliding during operation, thereby ensuring the stability and reliability of the entire device.
[0052] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
