[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1 - 4 , an embodiment provided by the present invention: A detachable oil fume purification and exhaust integrated machine, including an upper housing 2. The upper part of the upper housing 2 has an opening for connecting an external oil fume duct, which is convenient for discharging oil fume outdoors and convenient for installation and use;

[0023] The upper housing 2 is in communication with the lower housing 1. The lower part of the upper housing 2 is fixedly connected to the lower housing 1. The outside of the upper housing 2 is fixedly installed with a driving motor 4. The output end of the driving motor 4 is fixedly connected to a suction fan blade 3 and a secondary fan blade 301. The number of secondary fan blades 301 is two and is located outside the suction fan blade 3;

[0024] During the suction operation, the driving motor 4 is powered on to drive the suction fan blade 3 and the secondary fan blade 301 to rotate. Compared with a single rotating fan blade, the suction fan blade 3 and the secondary fan blade 301 have a greater suction force and a better suction effect. The rotation of the suction fan blade 3 and the secondary fan blade 301 can provide a good suction force, so that the oil fume is sucked from bottom to top, and the oil fume enters from the suction port 601.

[0025] Inside the lower housing 1, a protective plate 6 and an oil fume filter net 7 are fixedly connected. A suction port 601 is provided on the protective plate 6. The shape of the suction port 601 is rectangular. A discharge housing 101 is fixedly connected to the rear of the protective plate 6. A connecting column 102 is fixedly connected to the side of the discharge housing 101. A collection housing 5 is provided at the lower part of the discharge housing 101. The inside of the collection housing 5 has a collection cavity. The upper part of the collection housing 5 has an opening, and the opening is larger than the discharge housing 101. Two connecting hooks 501 are fixedly connected to the upper part of the collection housing 5, and they are arranged axially symmetrically. The connecting hooks 501 cooperate with the connecting column 102. There are corresponding grooves on the connecting column 102 to ensure the stability of the connecting hooks 501, thereby ensuring the stability of the collection housing 5. The protective plate 6 is inclined. The oil fume filter net 7 is located above the protective plate 6. The discharge housing 101 is in communication with the gaps between the oil fume filter net 7 and the protective plate 6. The oil fume filter net 7 has the same shape as the protective plate 6.

[0026] When cleaning is required, remove the connecting hook 501 from the connecting column 102, so that the collection housing 5 can be removed, facilitating the dumping of the collected oil fume. Similarly, the cleaned collection housing 5 can be reinstalled on the connecting column 102.

[0027] During use, the drive motor 4 is powered on to work, which can drive the suction fan blade 3 and the auxiliary fan blade 301 to rotate. The rotation of the suction fan blade 3 and the auxiliary fan blade 301 can provide good suction, enabling the oil fume to be sucked from bottom to top. The oil fume enters from the suction port 601 and is filtered and adsorbed by the oil fume filter net 7. The oil fume on the oil fume filter net 7 can gradually slide into the inside of the discharge housing 101 under the action of gravity and then fall into the inside of the collection housing 5. When cleaning is required, remove the connecting hook 501 from the connecting column 102, so that the collection housing 5 can be removed, facilitating the dumping of the collected oil fume. Similarly, the cleaned collection housing 5 can be reinstalled on the connecting column 102.

[0028] By providing the discharge housing 101, the protective plate 6, the oil fume filter net 7, and the collection housing 5, the filtered oil fume can be collected, and the collection housing 5 can be detached from the connecting column 102 for easy cleaning; the provided suction fan blade 3 and auxiliary fan blade 301 can provide good suction, with a relatively large suction force and being more durable in use.

[0029] Working principle: When in use, the driving motor 4 is powered on to drive the suction fan blade 3 and the auxiliary fan blade 301 to rotate. The rotation of the suction fan blade 3 and the auxiliary fan blade 301 can provide good suction, so that the oil fume is sucked from bottom to top. The oil fume enters from the suction port 601 and is filtered and adsorbed by the oil fume filter net 7. The oil fume on the oil fume filter net 7 can gradually slide into the interior of the discharge housing 101 under the action of gravity and then fall into the interior of the collection housing 5. When cleaning is required, the connecting hook 501 is removed from the connecting column 102, so that the collection housing 5 can be removed, facilitating the dumping of the collected oil fume. Similarly, the cleaned collection housing 5 can be reinstalled on the connecting column 102.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
