Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic interference, in particular to a device for weakening electromagnetic interference. Background Technique

[0002] Electromagnetic interference (EMI) refers to the interference generated by electromagnetic waves produced by electronic devices during operation on other electronics or systems. This interference may originate from the circuits and components inside the device or from electromagnetic waves in the external environment. When the frequency, amplitude, or phase of the interference signal is similar to that of the signal of the receiving device, it will have a negative impact on the normal operation of the receiving device. To weaken the impact of electromagnetic interference on the operation of electronic devices, a device for weakening electromagnetic interference is required. The structure included in the device for weakening electromagnetic interference generally has a filter, a mounting mechanism, a heat dissipation mechanism, and other auxiliary mechanisms.

[0003] In the prior art, most of the devices for weakening electromagnetic interference are installed using fixed structures or integral assembly mechanisms. When the filter is damaged, it is inconvenient to disassemble and repair, and it is necessary to replace the whole device to continue working, which increases the use cost of the device and reduces the practicability of the device. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a device for weakening electromagnetic interference, aiming to improve the problems of increased use cost and reduced practicability of the device for weakening electromagnetic interference in the prior art, which are mostly installed using fixed structures or integral assembly mechanisms.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A device for weakening electromagnetic interference includes a filter. The bottom of the filter is slidably connected to a mounting frame. Both sides of the mounting frame are fixedly connected with clamping blocks. The outside of both clamping blocks is slidably connected with buckles. The top ends of both buckles are fixedly connected with connecting plates. The outside of both connecting plates is rotatably connected with connecting clips. Two rigid plates are rotatably connected between the two connecting clips. The top end of one of the connecting plates is rotatably connected with a pressing plate. The bottom end of the pressing plate abuts against one end of the rigid plate. A heat dissipation mechanism is arranged at the top of the filter. The heat dissipation mechanism is provided to accelerate heat dissipation and improve the working efficiency of the filter.

[0006] As a further description of the above technical solution:

[0007] The heat dissipation mechanism includes heat dissipation fins and a blower. The bottom end of the heat dissipation fins is fixedly connected to the top end of the filter. Connecting columns are fixedly connected to the top corners of the heat dissipation fins. The top ends of the four connecting columns are fixedly connected to the bottom end of the blower. A connecting shaft is fixedly connected to the output end of the blower. An installation shell is fixedly connected to the bottom end of the connecting shaft. A plurality of springs are fixedly connected inside the installation shell. A limiting plate is fixedly connected to the bottom end of the spring. An extrusion plate is fixedly connected to the bottom end of the limiting plate. A brush is fixedly connected to the bottom end of the extrusion plate.

[0008] As a further description of the above technical solution:

[0009] A base is fixedly connected to the bottom end of the mounting bracket. Anti-slip pads are provided at the four corners of the bottom end of the base.

[0010] As a further description of the above technical solution:

[0011] Both of the rigid plates are slidably connected inside the filter.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to the end of the pressing plate away from the connecting plate. An anti-slip sleeve is sleeved on the outside of the handle.

[0014] As a further description of the above technical solution:

[0015] The limiting plate is slidably connected inside the installation shell. The extrusion plate penetrates through the bottom end of the installation shell.

[0016] As a further description of the above technical solution:

[0017] Fasteners are threadedly connected to the top ends of the four connecting columns.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the brush abuts against the top end of the heat dissipation fins.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present utility model, when the filter needs to be removed, push the handle upward so that the pressing plate presses the rigid plate downward. The two ends of the rigid plate move downward and push the connecting plate downward through the connecting clip, causing the buckle to disengage from the clamping block, and then the filter can be slid out of the mounting bracket. When installing the filter, just align the buckle with the clamping block, release the handle, and under the resilience of the rigid plate, the two connecting clips move upward simultaneously through the connecting plate, causing the buckle to engage and fix with the clamping block, thus fixing the filter well. This achieves the effect of convenient disassembly and installation of the filter. When the filter is damaged, it can be easily removed for repair without replacing the entire device, reducing the usage cost of the device and improving the practicality of the device.

[0022] 2. In the present utility model, start the fan, and the mounting shell rotates through the connecting shaft. The spring in the mounting shell provides elastic force and pushes the extrusion plate through the limiting plate, so that the bottom surface of the brush always fits against the top surface of the heat dissipation fins for automatic cleaning. This achieves the effect of automatically cleaning the heat dissipation fins, enhances the heat dissipation efficiency of the heat dissipation fins, extends the service life of the device, and improves the practicality of the device.
