After a certain period of use, the filter element of the heat dissipation, ventilation and purification device needs to be replaced. The traditional way of replacing the filter element requires the use of tools to unscrew the screws on the fixing frame before the filter element can be taken out from the fixing frame and replaced. This method of replacing the filter element is inefficient. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 It is understood that this utility model provides a technical solution: an electrical equipment heat dissipation, ventilation and purification device with a quick-replaceable filter element, including a fixed frame 1, an exhaust port 2, a filter element body 3 and a cooling fan 4. The front of the fixed frame 1 is provided with an exhaust port 2 for heat dissipation and ventilation inside the electrical equipment. The inside of the fixed frame 1 is provided with a filter element body 3 for filtering and purifying pollutants such as dust and oil mist inside the electrical equipment. The rear of the fixed frame 1 is provided with a cooling fan 4 for dissipating heat inside the electrical equipment. The top inner side of the fixed frame 1 is connected to a first limiting block 5 for limiting the filter element body 3. The bottom of the filter element body 3 is provided with a second limiting block 6 for limiting and supporting it. The bottom of the second limiting block 6 is connected to a sealing plate 7. Both ends of the sealing plate 7 are connected to fixed blocks 8. Both sides of the fixed frame 1 near the fixed blocks 8 are connected to connecting blocks 14. The inside of the fixed block 8 is connected to a plug-in block 9 for inserting into the inside of the connecting block 14. The inside of the plug-in block 9 is connected to a guide block 10 for sliding the moving plate 11.

[0024] exist Figure 1 , Figure 3 and Figure 4In the middle: the bottom of the connecting block 14 has a slot that matches the size of the plug-in block 9 and the card block 13, and the interior of the fixing block 8 and the plug-in block 9 are both provided with a through hole for pressing the moving plate 11 with a finger.

[0025] exist Figure 4 In the middle: the movable plate 11 is slidably connected to the outside of the guide block 10. The movable plate 11 and the plug block 9 are connected together by a reset spring 12 for the movable plate 11 to be pressed and reset. The outside of the movable plate 11 is connected to a locking block 13 for engaging and fixing with the connecting block 14.

[0026] In practice, replacing the filter element in traditional electrical equipment heat dissipation, ventilation, and purification devices requires using tools to unscrew the screws on the fixing frame 1 before replacing the filter element body 3. This replacement method is inefficient. When the filter element body 3 needs to be disassembled and replaced, two fingers can be inserted into the two sets of fixing blocks 8 and insertion blocks 9 through the corresponding through holes. At this time, the two fingers can press the moving plate 11 simultaneously. When the moving plate 11 is compressed, it can slide through the guide block 10. At the same time, the moving plate 11 will compress the return spring 12. When the return spring 12 is compressed to its maximum extent, the moving plate 11 can drive the locking mechanism. When the end of block 13 moves to the inside of the plug-in block 9, the locking block 13 is no longer locked inside the connecting block 14, so the sealing plate 7 can be pulled down. When the sealing plate 7 moves, it can drive the second limiting block 6 and the fixing block 8 to move. When the fixing block 8 moves, it can drive the end of the plug-in block 9 to slide out from inside the connecting block 14. When the second limiting block 6 moves, it can drive the filter element body 3 inside it to move out from inside the fixing frame 1 and the first limiting block 5. At this time, the finger can release the moving plate 11, so that the filter element body 3 can be quickly disassembled. Then the filter element body 3 can be taken out from inside the second limiting block 6 and a new filter element body 3 can be placed.

[0027] See Figures 1-4 As can be seen, by pressing the moving plate 11 with a finger, a new filter element body 3 is inserted into the fixed frame 1 and the first limiting block 5. The insertion block 9 can then be inserted into the connecting block 14. At this time, releasing the finger allows the reset spring 12 to reset, thereby resetting the moving plate 11 and the locking block 13. When the locking block 13 resets, it can engage in the slot inside the connecting block 14, thus fixing the position of the sealing plate 7 and the filter element body 3, thereby completing the replacement of the filter element body 3. The filter element body 3 can be quickly disassembled and replaced in this way, improving the replacement efficiency of the filter element body 3.

[0028] exist Figure 1 , Figure 5 and Figure 6In the middle: The top of the fixed frame 1 is connected to the fixed seat 15, the top of the fixed seat 15 is threaded to the threaded knob 16, the bottom of the threaded knob 16 is connected to the pressure plate 17 for pressing and fixing the mating block 19, the outside of the exhaust port 2 is provided with a baffle 18 for blocking the wind, and the side of the baffle 18 away from the exhaust port 2 is inclined. The side of the baffle 18 near the fixed seat 15 is connected to the mating block 19, and the inside of the fixed seat 15 is provided with a sliding groove that matches the size of the mating block 19.

[0029] exist Figure 1 , Figure 2 , Figure 5 and Figure 6 In the middle: the top of the docking block 19 is provided with a circular groove 20 for the pressure plate 17 to press and fix it, the baffle 18 is connected to the outer side of the fixed frame 1 with a positioning block 21, and the front part of the fixed frame 1 near the positioning block 21 is provided with a positioning groove.

[0030] In practice, since the fixed frame 1 on the heat dissipation, ventilation and purification device is usually installed on the outside of the electrical equipment, while the cooling fan 4 is located inside the electrical equipment, the hot air discharged from the exhaust vent 2 can easily cause harm to personnel when they pass through the exhaust vent 2. After the fixed frame 1 is installed on the electrical equipment with screws, the baffle 18 can be moved to the front of the exhaust vent 2 so that the end of the docking block 19 can pass through the sliding groove inside the fixed seat 15. At this time, the positioning block 21 on the baffle 18 can be inserted into the positioning groove at the front of the fixed frame 1, so that the threaded knob 16 can be rotated forward. When the threaded knob 16 is rotated forward, it can drive the pressure plate 17 to rotate and move closer to the docking block 19. When the pressure plate 17 rotates and moves into the circular groove 20, the pressure plate 17 can press and fix the docking block 19 through the threaded knob 16, thereby installing the baffle 18 at the front of the exhaust vent 2.

[0031] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that the baffle 18 can prevent the hot air discharged from the exhaust port 2 from blowing on the passing staff. At the same time, the inclined surface of the inner wall of the baffle 18 can guide the discharged hot air, so that the discharged hot air rises.
