Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coils, in particular to a fast trigger coil. Background Art
[0002] Trigger coils are mainly used in components that require instantaneous high voltage, such as the flash of road cameras and electronic hair removal devices. The specific working principle is to provide intermittent high voltage by energizing and transforming the primary and secondary coils wound around the outside of the magnetic core.
[0003] The existing trigger coil has an unstable high voltage output when the frequency is more than 2 times per second, and the output high voltage is lower than the design value. Hair removal products on the market, including skin rejuvenation products, require more than 5 times per second to be triggered. The existing coping method is to increase the output high voltage of the whole product to meet the problem of unstable high voltage output. Increasing the trigger output high voltage of the whole product to prevent high voltage ignition of the product will bring higher design requirements and production costs, and quality risks, so a fast trigger coil is needed.

[0006] Furthermore: the side surface of the frame is provided with openings, the number of the openings is two, and the openings are symmetrically distributed up and down.
[0007] Furthermore: an annular groove is provided on the inner side wall of the opening, and the two openings are connected through the annular groove, a spring is fixedly connected to the inner side wall of the annular groove, and a connecting ring is fixedly connected to one end of the spring away from the inner side wall of the annular groove.
[0008] Furthermore: the inner side wall of the annular groove is provided with a card slot, the number of the card slots is set to two, and they are symmetrically distributed front to back, and the two card slots and the two openings are cross-distributed.
[0009] Furthermore: a connecting frame is movably connected inside the annular groove, a clamping block is fixedly connected to the outer surface of the connecting frame, and the clamping block is engaged with the inside of the clamping groove, and the connecting frame is in contact with the side surface of the connecting ring.
[0010] Furthermore: a threaded ring is fixedly connected inside the connecting frame, a threaded cover is threadedly connected inside the threaded ring, a handle is fixedly connected to the side surface of the threaded cover, and one end of the magnetic core away from the limiting seat is located inside the threaded ring.
[0011] The utility model has the following beneficial effects:
[0012] 1. Compared with the prior art, by setting insulating rings and winding grooves, the secondary winding is wound in the winding grooves between the insulating rings during use, and then the magnetic core is installed inside the frame, and the primary winding is wound on the magnetic core. Due to its simple structure and good high-voltage insulation, it can quickly trigger high voltage and has stable output. When used in the design of products such as hair removal devices and skin rejuvenation devices, there is no need to add additional high-voltage protection treatment, which is conducive to enhancing the practicality of the device.
[0013] 2. Compared with the prior art, a connecting frame, a card block and a card slot are provided. When in use, the handle and the threaded cover are used to drive the card block outside the connecting frame to enter the annular groove from the opening, so that the connecting frame squeezes the connecting ring, thereby compressing the spring, which facilitates the card block to rotate outside the connecting ring. When the card block rotates to the card slot, the connecting ring pushes the card block under the push of the spring reaction force, so that it engages with the card slot. At the same time, the end of the magnetic core away from the limit seat is located inside the threaded ring. The threaded cover is then rotated by the handle, so that the threaded cover gradually moves and contacts the magnetic core, thereby limiting the magnetic core and preventing the magnetic core from shifting. It is convenient to put it into the sealing machine for vacuum injection and resin filling, which is beneficial to improving the convenience of device production. BRIEF DESCRIPTION OF THE DRAWINGS
