A sealing plate 22 is slidably connected to the side, covering one side of the vent 18. In use, the drive motor 16 can drive the exhaust fan 17 to rotate, so as to perform dust removal and ventilation treatment on the inside of the ventilation cap 3. The ventilation port 18 facilitates the air circulation inside the ventilation cap 3. The filter plate 20 can effectively filter the circulating air to prevent a large amount of dust or pollutants from entering the inside of the ventilation cap 3 through the ventilation port 18. During dust removal, the sealing plate 22 can be opened by sliding to allow dust removal and ventilation through the ventilation port 18. When waterproofing is required, the sealing plate 22 can be slid by sliding to seal and protect the ventilation port 18, thus facilitating the user to switch between waterproof and dust removal functions.

[0026] refer to Figures 1 to 3 A fixing block 6 is fixedly connected to one side of the top cover 5. A screw hole 7 is opened at the top of the fixing block 6. The screw hole 7 extends into the interior of the ventilation cap 3. A bolt 8 is threadedly connected to the inside of the screw hole 7. The bottom end of the bolt 8 is threaded into the interior of the ventilation cap 3 through the screw hole 7. Due to the presence of the bolt 8, the screwing in of the bolt 8 can effectively limit the position of the top cover 5 to prevent the top cover 5 from shifting. When it is necessary to clean or maintain the inside of the ventilation cap 3, the bolt 8 can be unscrewed by the thread principle, and then the top cover 5 can be pulled out directly. The top cover 5 can bring out the exhaust fan 17 structure together, which is convenient for subsequent cleaning of the inside of the ventilation cap 3 and also facilitates the user to maintain the structure on the top cover 5 later.

[0027] refer to Figures 1 to 3The bottom inner side of the limiting groove 4 is provided with a positioning groove 12. The bottom of the top cover 5 is fixedly connected with a positioning block 15 that matches the positioning groove 12.

The positioning block 15 is located on the outside of the adjacent first sealing ring 14. Due to the presence of the positioning block 15, the snapping of the positioning block 15 can further improve the stability of the top cover 5 position fixation. At the same time, it can also improve the accuracy of the bolt 8 position screwing in, so as to further reinforce the stability of the top cover 5 position fixation. The first sealing ring 14 can effectively seal the connection point of the top cover 5, thereby achieving a good waterproof sealing effect.

[0028] refer to Figure 1 The top of the top cover 5 has an opening 9 that passes through the top cover 5. An observation window 10 is fixedly connected to the inner wall of the opening 9 and covers the inside of the opening 9. Because of the opening 9, the user can directly look at the inside of the ventilation cap 3 through the observation window 10 without opening the top cover 5, which is conducive to the user observing the ventilation status inside the ventilation cap 3 at all times.

[0029] refer to Figures 1 to 5 The top of the connecting frame 2 is provided with a threaded groove 26, and the bottom of the vent cap 3 is fixedly connected with a threaded frame 28 that matches the threaded groove 26. The threaded frame 28 is threaded to the inside of the threaded groove 26. The vent cap 3 is threaded to the top of the connecting frame 2 through the threaded groove 26 and the threaded frame 28. The top of the connecting frame 2 is fixedly connected with a second sealing ring 27. The top of the second sealing ring 27 is in contact with the bottom of the vent cap 3. Due to the presence of the threaded frame 28, it is convenient for the vent cap 3 and the connecting frame 2 to connect with each other. When the threaded frame 28 is unscrewed, the connecting frame 2 and the vent cap 3 will also separate, which is convenient for the user to disassemble and maintain them later. Due to the presence of the second sealing ring 27, the second sealing ring 27 can effectively seal the bottom of the vent cap 3, which can play a good waterproof sealing role, thereby effectively improving the safety of the connection and use of the vent cap 3.

[0030] refer to Figure 6 A third sealing ring 29 is fixedly connected to the bottom end of the mounting base 1. The third sealing ring 29 covers the bottom end of the mounting base 1. The thickness of the third sealing ring 29 is five millimeters. The third sealing ring 29 is made of rubber material. Due to the presence of the third sealing ring 29, the connection point of the mounting base 1 can be effectively sealed, which can effectively improve the sealing effect of the overall ventilation cap 3.

[0031] refer to Figure 1 and Figure 2The ventilation cap 3 has a second groove 21 on one side that matches the sealing plate 22. The sealing plate 22 is slidably connected to one side of the ventilation cap 3 through the second groove 21. A protrusion 23 is fixedly connected to one side of the sealing plate 22. The protrusion 23 has an arc-shaped corner. A groove 24 is provided on one side of the ventilation cap 3. A magnet 25 is fixedly connected to the inside of the groove 24. The magnet 25 covers the inside of the groove 24. One side of the magnet 25 corresponds to the other side of the sealing plate 22. The other side of the sealing plate 22 is made of magnetic material. Due to the presence of the magnet 25, when the sealing plate 22 is closed, the magnet 25 can effectively attract the sealing plate 22 to prevent it from slipping off. At the same time, it will not hinder the subsequent opening and use of the sealing plate 22.

[0032] Operating principle and advantages: During use, the drive motor 16 drives the exhaust fan 17 to rotate, thereby ventilating and removing dust from the inside of the ventilation cap 3. The vent 18 facilitates airflow within the ventilation cap 3, and the filter plate 20 effectively filters the airflow to prevent large amounts of dust or pollutants from entering the ventilation cap 3 through the vent 18. During dust removal, the sealing plate 22 can be opened via a sliding mechanism to allow ventilation and dust removal through the vent 18. When waterproofing is required, the sealing plate 22 can be slid down to seal and protect the vent 18, thus facilitating... When users switch between waterproof and dust removal functions, the presence of bolt 8 effectively limits the position of the top cover 5 to prevent displacement. When cleaning or maintenance of the inside of the ventilation cap 3 is required, bolt 8 can be unscrewed using the thread principle, and then the top cover 5 can be pulled out directly. The top cover 5 can also bring out the exhaust fan 17 structure, facilitating subsequent cleaning of the inside of the ventilation cap 3 and allowing for later maintenance of the structure on the top cover 5. The presence of positioning block 15 further enhances the stability of the top cover 5's position and also improves the tightening of bolt 8. To ensure accuracy and stability of the top cover 5 position, the first sealing ring 14 effectively seals the connection point of the top cover 5, thus achieving a good waterproof sealing effect. Due to the opening 9, the user can directly observe the inside of the ventilation cap 3 through the observation window 10 without opening the top cover 5, facilitating constant monitoring of the ventilation status inside the ventilation cap 3. The presence of the threaded frame 28 facilitates the connection between the ventilation cap 3 and the connecting frame 2. When the threaded frame 28 is unscrewed, the connecting frame 2 and the ventilation cap 3 will separate, allowing for easy subsequent adjustments by the user. During disassembly and maintenance, the presence of the second sealing ring 27 effectively seals the bottom of the ventilation cap 3, providing a good waterproof seal and thus improving the safety of the ventilation cap 3 connection. The presence of the third sealing ring 29 effectively seals the connection point of the mounting base 1, improving the overall sealing effect of the ventilation cap 3. The presence of the magnet 25 allows the sealing plate 22 to be effectively attracted when it is closed, preventing it from slipping and allowing it to be opened later.
