[0016] 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.

[0017] Please see Figures 1-3In this embodiment of the utility model, a vehicle-mounted ventilation device with oil fume purification function includes a purification box 1. One end of the purification box 1 is connected to a vehicle-mounted range hood through a pipe, and the other end of the purification box 1 is connected to a suction fan through a pipe. An installation part 2 is clamped on the outside of the purification box 1 and fixedly connected to the top of the vehicle interior. A sealing door 3 is installed on one side of the installation part 2 through a connecting mechanism. A purification mechanism penetrating into the inner cavity of the purification box 1 is installed at one end of the sealing door 3. A handle 4 is fixedly installed at the front end of the sealing door 3. A slot for inserting the purification mechanism is opened on one end plate of the purification box 1.

[0018] In this embodiment: First, when installing the purification mechanism, the handle 4 drives the sealing door 3 upward, which in turn drives the purification mechanism upward until the purification mechanism is aligned with the slot on the purification box 1. Then, the sealing door 3 is pushed, and the sealing door 3 drives the purification mechanism into the purification box 1. The sealing door 3 is then limited by the connecting mechanism. A rubber sealing ring is installed at the contact point between the sealing door 3 and the purification box 1, which can effectively ensure that the purification box 1 maintains effective sealing during the purification of oil fumes. Similarly, after the purification mechanism has been used for a long time, the connecting mechanism can be disassembled. After disassembly, the sealing door 3 is separated from the purification box 1, and the purification mechanism is disassembled. Then, the intercepting net 17 is disassembled by the docking mechanism, which allows for efficient cleaning of the purification mechanism without disassembling the sealing door 3 from the purification mechanism, thus achieving high cleaning efficiency.

[0019] Please refer to this carefully. Figure 1 and Figure 2 The connecting mechanism includes a receiving groove 7 opened on the outside of a vertical plate of the mounting part 2. A stud 8 protruding outward is welded at the center of the arc-shaped part of the receiving groove 7. Both ends of the sealing door 3 are integrally formed with outward protruding fixing ears 5. A round hole that mates with the stud 8 is provided at the center of the fixing ear 5. A nut 19 for pressing the fixing ear 5 is threadedly connected to the outer wall of the stud 8.

[0020] In this embodiment: when installing the sealing door 3 through the docking mechanism, the round hole on the fixing ear 5 is aligned with the stud 8 and inserted. Then, the nut 19 is tightened on the outer wall of the stud 8. After the nut 19 is tightened, it effectively presses the fixing ear 5. At this time, the rubber sealing ring on the sealing door 3 deforms under force, effectively sealing the gap between the two to ensure the airtightness of the purification box 1.

[0021] Please refer to this carefully. Figure 2 and Figure 3The purification mechanism includes two frames 9 fixedly connected to the sealing door 3. The two frames 9 are symmetrically distributed about the vertical central axis of the sealing door 3. A second insulating frame 11 is fixedly installed on one side of the sealing door 3 between the two frames 9. Multiple anode cylinders 12 are welded inside the second insulating frame 11. A first insulating frame 10 fixedly connected to the sealing door 3 is set between one frame 9 and the second insulating frame 11. A conductor 16 is fixedly installed on the inner side of the first insulating frame 10. A cathode needle 13 penetrating into the inner cavity of the anode cylinder 12 is fixedly installed on the conductor 16. An intercepting net 17 is detachably connected to the frame 9 through a docking mechanism. Two sets of wire holes 6 are opened on the sealing door 3. The conductor of the conductor 16 passes through one set of wire holes 6 and is electrically connected to an external power source. The conductor of the anode cylinder 12 passes through the other set of wire holes 6 and is electrically connected to an external power source. A sealing element is set at the contact position between the conductor and the two sets of wire holes 6.

[0022] In this embodiment: When purifying oil fumes, the device is connected to the power supply, and the external power supply delivers high-voltage DC voltage to the anode cylinder 12 and cathode needle 13 to form an electric field. After the range hood inputs the oil fumes generated by cooking in the RV into the purification box 1, large oil fume particles in the oil fume are intercepted by the interceptor net 17 near the inlet, and then enter the inner wall of the anode cylinder 12. At this time, the oil fume is ionized under the electric field, and the passing oil fume particles will carry electrons and negative ions, which will be deposited and accumulated on the inner wall of the anode cylinder 12, completing the purification and separation. The ventilation mechanism exhausts the air outward, while the interceptor net 17 near the outlet can prevent impurities from being discharged outward.

[0023] Please refer to this carefully. Figure 3 The docking mechanism includes an opening slot 14 on the top plate of the frame 9 and a snap-fit ​​slot 15 on the bottom plate of the frame 9. The bottom end of the interception net 17 is integrally formed with a downwardly protruding snap-fit ​​plate 18. The outer wall of the snap-fit ​​plate 18 matches the outer wall of the snap-fit ​​slot 15. The thickness of the interception net 17 is equal to the width of the opening slot 14.

[0024] In this embodiment: When the purification mechanism needs to be cleaned after a long period of use, the sealing door 3 is disassembled. After disassembly, the purification mechanism is pulled out of the purification box 1 through the sealing door 3. Since there is a certain amount of oil smoke or impurities attached to the front end surface of the two intercepting nets 17, there is a large resistance during disassembly. At this time, a tool is inserted from the bottom opening of the snap-fit ​​groove 15 and a squeezing force is applied to the bottom end of the snap-fit ​​plate 18. Under the squeezing force, the intercepting net 17 can move outward through the opening groove 14. After the intercepting net 17 is removed, the opening of the anode cylinder 12 is exposed, which makes it convenient to clean the inner wall of the anode cylinder 12 and to clean the removed intercepting net 17.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
