Description

Technical Field

[0001] This utility model relates to the field of high voltage transformer technology, specifically to an arc high voltage transformer. Background Technology

[0002] A lighter is a small fire-starting device, mainly used for smoking, but also for cooking and other purposes. Currently, commonly used lighters include those with electronic ignition, piezoelectric ceramic ignition, and friction ignition. Although these lighters have been used for many years and are technologically mature, they still require fuel such as gasoline or liquefied petroleum gas, which presents problems such as inconvenience, safety concerns, and uncleanliness for users. To solve the fuel problem, arc lighters were developed.

[0003] Existing high-voltage arc lighter coils include a frame with through holes, a magnetic core, a primary winding coil, a secondary winding coil, an insulating diaphragm, and two high-voltage wires. The magnetic core is embedded in the through holes of the frame. Both the primary and secondary winding coils are wound around the frame. Insulating tape is placed between the secondary and primary winding coils, and the secondary winding coil is further secured with adhesive tape. Assembly requires four steps: winding, adhesive wrapping, winding, and adhesive wrapping. This process is complex and results in high production costs. Therefore, it is necessary to design an arc high-voltage coil structure that is easy to process and has low production costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an arc high voltage transformer.

[0005] The technical solution adopted by this utility model is as follows: an arc high voltage transformer includes a frame, a magnetic core, a primary winding, and a secondary winding. The frame is provided with a magnetic core hole for inserting the magnetic core. The outer periphery of the frame is provided with a secondary winding area for winding the secondary winding. The primary winding is a shaped winding. The frame is provided with a positioning block for fixing the primary winding at one end in the axial direction of the magnetic core hole. The primary winding and the secondary winding are arranged side by side and concentrically along the axial direction of the magnetic core hole.

[0006] Preferably, the positioning block is connected to a position on the frame other than the core hole, and a slot is provided at one end of the positioning block near the core hole, into which the primary winding is inserted radially.

[0007] Preferably, a first pin is inserted through the center of the positioning block, one end of the first pin is connected to the secondary winding, and the other end is connected to the first high-voltage line.

[0008] Preferably, the skeleton has a protrusion in the axial direction of the core hole, which is different from the positioning block. A second pin is inserted through the center of the protrusion. One end of the second pin is connected to the secondary winding, and the other end is connected to a second high-voltage line.

[0009] Preferably, the magnetic core includes a first magnetic core and a second magnetic core, which are inserted into the magnetic core hole from both ends of the magnetic core hole. The first magnetic core and the second magnetic core are respectively provided with U-shaped outer magnetic cores with opposite openings outside the frame. The outer magnetic cores are combined to form an outer magnetic ring surrounding the frame.

[0010] Preferably, the first magnetic core is inserted into the core hole from the end closest to the primary winding, and the length of the first magnetic core is greater than the length of the second magnetic core.

[0011] Preferably, the length of the outer magnetic core disposed on one side of the first magnetic core is greater than the length of the outer magnetic core disposed on one side of the second magnetic core.

[0012] Preferably, there is a magnetic gap between the first magnetic core and the second magnetic core.

[0013] Preferably, the length of the outer magnetic core on one side of the second magnetic core is greater than the length of the second magnetic core, and the length of the outer magnetic core on one side of the first magnetic core is equal to or less than the length of the first magnetic core.

[0014] Preferably, the skeleton is provided with a plurality of wire grooves arranged sequentially along the axial direction around the secondary winding area, and the skeleton has a winding notch between adjacent wire grooves for the wires in the secondary winding to be wound into the adjacent wire groove.

[0015] The beneficial effects of this utility model are as follows: the primary winding and the secondary winding are arranged side by side. Compared with the traditional form of winding them sequentially on the frame, there is no need to wind an insulation structure between them. At the same time, since the primary winding is a pre-formed winding, it can be manufactured simply by first processing it into a winding and then fixing it on the positioning block to complete the installation.

Detailed Implementation

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0026] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown in the figure, in an embodiment of this utility model, an arc high voltage transformer includes a frame 1, a magnetic core, a primary winding 3, and a secondary winding 4. The frame 1 is provided with a magnetic core hole 11 for inserting the magnetic core. The outer periphery of the frame 1 is provided with a secondary winding area for winding the secondary winding 4. The primary winding 3 is a shaped winding. One end of the frame 1 in the axial direction of the magnetic core hole 11 is provided with a positioning block 12 for fixing the primary winding 3. The primary winding 3 and the secondary winding 4 are arranged side by side and concentrically along the axial direction of the magnetic core hole 11.

[0028] With this configuration, the primary and secondary windings are arranged side by side. Compared to the traditional method of winding them sequentially onto the frame, there is no need to wind an insulation structure between them. In addition, since the primary winding is a pre-formed winding, it can be manufactured simply by first processing it into a winding and then fixing it onto the positioning block to complete the installation. There is no need to wind it onto the positioning block and then wrap its outer periphery with tape to make the structure stable and not easy to fall apart, which greatly saves the production process and cost of this device.

[0029] The primary winding is a pre-formed winding, meaning it has been processed into a winding shape and can maintain that shape. In this embodiment, it is specifically a copper wire with a self-adhesive copper wire coated with a special thermosetting adhesive. When it is necessary to fix the copper wire, heat is simply applied to the area where it needs to be bonded, usually using a soldering iron, hot air gun, or a special heating tool. The heat will melt and activate the adhesive on the surface. The adhesive will then cool and solidify rapidly, forming a strong bond, thus achieving both electrical conductivity and mechanical fixation.

[0030] The primary winding can be fixed to the positioning block in the following ways: 1. The primary winding is sleeved outside the positioning block. In this case, the positioning block should be set to be coaxial with the skeleton, and the core hole of the skeleton passes through the positioning block; 2. The primary winding is clamped at the positioning block. In this case, the positioning block should be set to be connected to the skeleton at a position different from the core hole, and the positioning block is provided with a slot that matches the shape of the primary winding.

[0031] The positioning block 12 is connected to the frame 1 at a position different from the core hole 11. The end of the positioning block 12 near the core hole 11 is provided with a slot 121, and the primary winding 3 is inserted into the slot 121 radially.

[0032] With this design, the positioning block is relatively fixed to the primary winding through the slot, simplifying the structure. At the same time, during subsequent installation processes, the primary winding is less likely to detach from the slot, maintaining a stable relative position with the frame, thus improving processing efficiency and yield.

[0033] The center of the positioning block 12 is provided with a first pin 122 that penetrates the positioning block 12. One end of the first pin 122 is connected to the secondary winding 4, and the other end is connected to the first high voltage line 5.

[0034] The frame 1 has a protrusion 13 in the axial direction of the core hole 11, which is different from the positioning block 12. A second pin 131 is inserted through the center of the protrusion 13. One end of the second pin 131 is connected to the secondary winding 4, and the other end is connected to the second high voltage line 6.

[0035] This design makes efficient use of space, allowing for a smaller size of the compatible lighter.

[0036] The magnetic core includes a first magnetic core 21 and a second magnetic core 22. The first magnetic core 21 and the second magnetic core 22 are respectively inserted into the magnetic core hole 11 from both ends. The first magnetic core 21 and the second magnetic core 22 are respectively provided with U-shaped outer magnetic cores 23 with opposite openings outside the frame 1. The outer magnetic cores 23 are combined to form an outer magnetic ring surrounding the frame 1.

[0037] This setting increases the magnetic field strength of the outer magnetic ring, thereby achieving a voltage boosting effect.

[0038] The first magnetic core 21 is inserted into the magnetic core hole 11 from the end closest to the primary winding 3, and the length of the first magnetic core 21 is greater than the length of the second magnetic core 22.

[0039] This setting can effectively reduce the leakage inductance of this high-voltage transformer.

[0040] The length of the outer magnetic core 23 located on one side of the first magnetic core 21 is greater than the length of the outer magnetic core 23 located on one side of the second magnetic core 22.

[0041] This setting further reduces the leakage inductance of this high-voltage transformer.

[0042] A magnetic gap 24 is provided between the first magnetic core 21 and the second magnetic core 22.

[0043] The length of the outer magnetic core 23 on one side of the second magnetic core 22 is greater than the length of the second magnetic core 22, and the length of the outer magnetic core 23 on one side of the first magnetic core 21 is equal to or less than the length of the first magnetic core 21.

[0044] This setting further reduces the leakage inductance of this high-voltage transformer.

[0045] The skeleton 1 is surrounded by a plurality of wire grooves 14 arranged sequentially along the axial direction in the secondary winding area. The skeleton 1 has a winding notch 15 between adjacent wire grooves 14 for the wires in the secondary winding 4 to be wound into the adjacent wire grooves 14.

[0046] With this setup, the wire can be wound through the winding notch to the adjacent wire groove, making the winding structure more compact.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
