For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] The embodiment of the present application provides a pulse generating device with a pulse generating unit. The pulse generating device provided by the present application can be a small device or a large device; the pulse unit can be applied to a small device, and correspondingly, can also be applied to a large device.

[0040] As shown in Figures 1 to 4 The pulse generating unit provided by the embodiment of the present application includes a support 200 and at least one pair of pulse generators 100; in some embodiments, it can also include two pairs, three pairs or even more pairs of pulse generators 100; in some embodiments, it can also include three, five pulse generators 100. Wherein, one pair of pulse generators 100 includes two pulse generators 100, and each pulse generator 100 includes a circuit board 110 and a magnetic ring assembly 120, wherein the circuit board 110 is a plate-shaped structural member, the magnetic ring assembly 120 is a columnar structural member, the space occupied by the magnetic ring assembly 120 is relatively large, and the circuit board 110 and the magnetic ring assembly 120 are connected by a wire 130. The two circuit boards 110 have oppositely arranged first sides, each first side has an adjacent first region and a second region, the first region is used for arranging a charging circuit for supplying power to the magnetic ring assembly 120, and the second region is used for arranging a mos tube, a discharge circuit and a control circuit and the like. The first region is connected with the corresponding magnetic ring assembly 120 for charging the magnetic ring assembly 120. The first regions and the second regions of the two first sides are staggered, one magnetic ring assembly 120 is located between one first region and one second region, and the other magnetic ring assembly 120 is located between the other first region and the other second region.

[0041] Exemplarily, please refer to Figure 1 , Figure 2 and Figure 5The first region of the circuit board 110 on one side is located below the second region, and the first region of the circuit board 110 on the other side is located above the second region, so as to realize the staggered arrangement of the first region and the second region. Since one magnetic ring assembly 120 is located between one first region and one second region, and another magnetic ring assembly 120 is located between another first region and another second region, the two magnetic ring assemblies 120 are also arranged in the vertical direction. Further, in the embodiment with two or more pairs of pulse generators 100, each pair of pulse generators 100 can be arranged in the horizontal direction or the vertical direction.

[0042] It can be understood that, since the first sides of the two circuit boards 110 are arranged opposite to each other, and one magnetic ring assembly 120 is located between one first region and one second region, and another magnetic ring assembly 120 is located between another first region and another second region, the magnetic ring assemblies 120 in the pulse generation unit are also arranged alternately and more compactly. The magnetic ring assemblies 120 arranged in this way can not only ensure the consistency of the magnetic field direction, but also effectively utilize the space according to the structure of the pulse generator 100, so as to improve the space utilization between the two circuit boards 110, make the whole pulse generation unit compact, and effectively utilize the limited space in small devices, so that the pulse generation unit provided by the present application can be applied to small pulse generation devices and the like.

[0043] In some other embodiments, the circuit boards 110 can also be arranged horizontally, and the two magnetic ring assemblies 120 can be arranged left and right in the horizontal direction. Further, in the embodiment with two or more pairs of pulse generators 100, each pair of pulse generators 100 can be arranged in the horizontal direction or the vertical direction.

[0044] In some embodiments, as shown in Figure 6 The circuit board 110 and the magnetic ring assembly 120 of one pulse generator 100 are fixed to the first frame body 210, and the circuit board 110 and the magnetic ring assembly 120 of another pulse generator 100 are fixed to the second frame body 220. In this embodiment, by arranging the opposite first frame body 210 and the second frame body 220 to mount one pair of pulse generators 100, the first side of the circuit board 110 in the two pulse generators 100 can be conveniently mounted to the opposite positions, and then the two magnetic ring assemblies 120 can be conveniently mounted between the two circuit boards 110, so as to make the structure of the pulse generation unit more compact. Further, please refer to Figure 1 and Figure 6When the pulse generating unit has two or more pairs of pulse generators 100, multiple first frames 210 and second frames 220 can be set in the horizontal direction to install multiple pairs of pulse generators 100; or the vertical dimensions of the first frames 210 and second frames 220 can be increased to install multiple pairs of pulse generators 100.

[0045] Furthermore, the magnetic ring assembly 120 is disposed between the first frame 210 and the second frame 220, with its peripheral surfaces facing both the first frame 210 and the second frame 220. This allows the first frame 210 and the second frame 220 to protect the magnetic ring assembly 120 and makes the shape of the pulse generating unit more regular, facilitating installation. Furthermore, the axis of the magnetic ring assembly 120 is square and parallel to the plane containing the first frame 210.

[0046] In some embodiments, the magnetic ring assembly 120 and the circuit board 110 are respectively connected to both sides of the first frame 210. Further, a first side of the circuit board 110 of a pulse generator 100 is connected to one side of the first frame 210, and the magnetic ring assembly 120 is connected to the opposite side of the first frame 210. Specifically, the circuit board 110 of one pulse generator 100 is connected to the side of the first frame 210 facing away from the second frame 220, and the magnetic ring assembly 120 is connected to the side of the first frame 210 facing the second frame 220. Correspondingly, the circuit board 110 of another pulse generator 100 is connected to the side of the second frame 220 facing away from the first frame 210, and the magnetic ring assembly 120 is connected to the side of the second frame 220 facing the first frame 210. In this embodiment, both the circuit board 110 and the magnetic ring assembly 120 of a pulse generator 100 are connected to either the first frame 210 or the second frame 220, making the installation of the pulse generator 100 more stable and reliable.

[0047] Furthermore, in some embodiments, the pulse generator 100 is fixed to the first frame 210 and the second frame 220 by threaded fasteners. Specifically, the circuit board 110 of the pulse generator 100 is fixed to the side of the first frame 210 facing away from the second frame 220 by threaded fasteners, and the magnetic ring assembly 120 is fixed to the side of the first frame 210 facing the second frame 220 by threaded fasteners. The threaded fasteners can be bolts and nuts, or they can be threaded holes directly provided in the first frame 210 and the second frame 220.

[0048] Furthermore, in some embodiments, the first frame 210 is also provided with columnar structures, some of which are screw posts with threaded holes for connection with bolts, thereby fixing the circuit board 110 and the magnetic ring assembly 120 to the first frame 210. Other columnar structures are positioning posts, used to position the circuit board 110 and the magnetic ring assembly 120 during installation, facilitating their installation and fixing. Specifically, when installing the magnetic ring assembly 120, the positioning holes of the magnetic ring assembly 120 are first aligned with the corresponding positioning posts in the first frame 210, and then the screw holes of the magnetic ring assembly 120 are aligned with the corresponding screw posts before being screwed into the threaded fasteners. When installing the circuit board 110, the positioning holes of the circuit board 110 are first aligned with the corresponding positioning posts in the first frame 210, and then the screw holes of the circuit board 110 are aligned with the corresponding screw posts before being screwed into the threaded fasteners.

[0049] like Figure 1 As shown, in some embodiments, the first frame 210, the second frame 220, and the circuit boards 110 of the two pulse generators 100 are all vertically arranged; the magnetic ring assemblies 120 of the two pulse generators 100 are arranged vertically. In other embodiments, the second frame 220 and the circuit boards 110 of the two pulse generators 100 may be horizontally arranged; the magnetic ring assemblies 120 of the two pulse generators 100 may be arranged horizontally. Those skilled in the art can reasonably select the arrangement of the pulse generating units according to the internal space of the pulse generating device.

[0050] In some embodiments, the bracket 200 further includes a third frame 230, to which the first frame 210 and the second frame 220 are connected; the third frame 230 is also provided with a connecting portion 231, which has a through hole; the through hole is used for fasteners to pass through to fix the third frame 230. That is, the third frame 230 can be installed and fixed on other structures by fasteners, and the first frame 210 and the second frame 220 are connected side by side to the third frame 230, so the bracket 200 can be installed and fixed by installing and fixing the third frame 230.

[0051] In some embodiments, the bracket 200 further includes a bracket connecting strip 240, one end of which is detachably connected to the top of the first frame 210 and the other end of which is detachably connected to the top of the second frame 220. A third frame 230 is connected to the bottom of the first frame 210 and the second frame 220 to make the upper part of the bracket 200 lighter, thereby making the structure of the bracket 200 more stable. By setting the bracket connecting strip 240 between the first frame 210 and the second frame 220, the structural strength of the bracket 200 can be improved, preventing the first frame 210 and the second frame 220 from deforming outward. Since the bracket connecting strip 240 is detachably connected to the first frame 210 and the second frame 220, if the setting position of the bracket connecting strip 240 interferes with the disassembly and assembly process of the pulse generator 100, the bracket connecting strip 240 can be removed to facilitate the installation of the magnetic ring assembly 120 between the first frame 210 and the second frame 220.

[0052] Furthermore, in some embodiments, two support connecting strips 240 are connected between the top end of the first frame 210 and the top end of the second frame 220; the top end of the first frame 210, the support connecting strip 240, the top end of the second frame 220, and the other support connecting strip 240 form a channel for the magnetic ring assembly to pass through. It is easy to understand that because the magnetic ring assembly 120 is relatively large, the entrance size of the channel is also large, resulting in lower structural strength of the support 200 at the entrance of the channel. Therefore, placing the support connecting strip 240 at the entrance of the channel can prevent deformation of the first frame 210 and the second frame 220. Furthermore, placing the support connecting strip 240 at the entrance of the channel also allows for disassembly of the support connecting strip 240 to facilitate the assembly and disassembly of the magnetic ring assembly 120; furthermore, it can also serve as a handle for easy handling of the pulse generating unit.

[0053] In some embodiments, the support connecting strip 240 may be connected to the side of the first frame 210 and the second frame 220 opposite to the third frame 230, or it may be connected to the side of the first frame 210 and the second frame 220 adjacent to the third frame 230, or a support connecting strip 240 may be provided on each side of the first frame 210 and the second frame 220. The support connecting strip 240 may be a strip-shaped structure, a plate-shaped structure, or a structure of other shapes.

[0054] Please refer to Figure 1 and Figure 6The bracket connecting strip 240 and the third frame 230 are located on two opposite sides of the bracket 200. The bracket connecting strip 240 can prevent outward deformation and also serve as a handle for easy extraction of the pulse generating unit. In other embodiments, the bracket connecting strip 240 may also be connected to the side of the first frame 210 and the second frame 220 adjacent to the third frame 230.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
