[0026] In this embodiment, placement grooves 9 are provided on the top of the cabinet 1 and on both sides of the through hole 3, and the connecting block 5 is located inside the placement grooves 9. By providing the placement grooves 9, the connecting block 5 can be placed under the action of the placement grooves 9, thereby achieving the purpose of limiting the position of the connecting block 5.

[0027] In this embodiment, grooves 10 are provided on both sides of the surface of the cabinet 1, and the block 61, the limit block 63, the spring 64 and the pull rod 62 are all located inside the groove 10, and the other end of the spring 64 is fixedly connected to the inner wall of the groove 10.

[0032] The working principle of the utility model is as follows: when in use, the spring 64 is in the initial state, and the device is first connected to the external power supply. When the inside of the cabinet 1 needs to be cooled, the corresponding control button 13 is pressed, and the cooling fan 8 starts to operate. When the cooling fan 8 is in operation, an airflow is generated, driving the air outside the cabinet 1 to enter the inside of the cabinet 1 through the through hole 3. When the air enters the inside of the cabinet 1, the heat generated by the electrical components inside the cabinet 1 is driven to be discharged from the cabinet 1 through the heat dissipation port 14 with the air, so that the inside of the cabinet 1 can be cooled. At the same time, the air outside the cabinet 1 enters the inside of the cabinet 1 and contacts the filter 4. The dust in the air can be filtered through the filter 4 to prevent the dust from entering the inside of the cabinet 1 and adhering to the surface of the electrical components. When the filter 4 is damaged and needs to be disassembled and replaced, the user pulls one side of the pull rod 62 to move toward the outside of the cabinet 1, and the pull rod 62 moves. At the same time, the limit block 63 is driven to slide inside the limit groove 15, and the block 61 is also driven to move and the extrusion spring 64 is contracted. When the block 61 moves, one side of the block 61 is pulled out of the interior of the connecting block 5. At the same time, the user grabs the handle 11 and moves it upward, driving the connecting block 5 and the filter screen 4 to move out of the placement groove 9 and the through hole 3 respectively, so that the damaged filter screen 4 can be disassembled without the need for professional tools. When installing the filter screen 4, the filter screen 4 and the connecting block 5 are respectively placed in the through hole 3 and the placement groove 9, and the pull rod 62 is released at the same time. Under the elastic force of the spring 64 itself, the block 61, the limit block 63 and the pull rod 62 are driven to reset and move. When the block 61 moves, it is inserted into the interior of the connecting block 5, so that the positions of the connecting block 5 and the filter screen 4 can be clamped and fixed, and the filter screen 4 can be installed.
