[0002] Oil fume purifiers are equipment used in the kitchens of catering establishments to treat oil fumes. Their main function is to purify the oil fumes emitted from the kitchen, preventing them from polluting and harming the environment and human health. By purifying the oil fumes, oil fume emissions are reduced and indoor air quality is improved.

[0003] In the prior art, Chinese Patent No. CN217763583U discloses a circulating fume purifier, relating to the field of fume purification equipment technology. It includes a main body and a suction hood. The suction hood is located at the lower end of the main body, and a control box is located on one side of the main body. The interior of the main body is divided into a purification chamber and a power chamber by a partition. The purification chamber contains a first purification layer, a second purification layer, a third purification layer, a fourth purification layer, and a fifth purification layer arranged sequentially. An air duct communicating with the purification chamber is located on one side of the suction hood. A suction fan is installed inside the power chamber, and an air inlet pipe is fixedly connected to the air inlet end of the suction fan. One end of the air inlet pipe passes through the partition and communicates with the purification chamber. Through the arrangement of five purification layers and a purification electric field, the device can perform multiple purification processes and multiple purification methods on the inhaled fumes, greatly enhancing the equipment's purification capacity for fumes and preventing the overflow of incompletely purified fumes that could harm the environment.

[0004] However, in the aforementioned disclosed technologies, existing methods for filtering oil fumes often rely on filter materials to purify the fumes. Furthermore, existing filter equipment is primarily fixed using multiple sets of positioning bolts, making it inconvenient to remove and clean the equipment. Therefore, this invention proposes an oil fume purifier that facilitates the replacement of filter components to address these issues. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model proposes an oil fume purifier that facilitates the replacement of filter components. When the filter material inside the oil fume purifier body needs cleaning after prolonged use, the sealing cover can be opened first, allowing the support plate to be pulled out from the exhaust port. This allows all the filter materials to be removed. Then, the positioning ring can be rotated using the hinge to disengage it from the positioning rod, allowing the rubber plate to be removed. This makes it convenient to remove and clean individual filter materials. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: an oil fume purifier that facilitates the replacement of filter components, including an oil fume purifier body 1, an oil fume purifier body 1 having a smoke inlet 16 on its side, an exhaust outlet 2 inside the oil fume purifier body 1, a movable groove 3 on the surface of the exhaust outlet 2, and a limiting groove 4 on the side of the movable groove 3.

[0027] Support plate 5, positioning plate 6 is provided on the surface of support plate 5, positioning slot 7 is provided on the surface of positioning plate 6, and positioning ring 8 is provided on the side of positioning plate 6;

[0028] The filter frame 9 has a filter media 10 inside, a rubber plate 11 at the bottom, and a positioning rod 12 on the side.

[0029] When the filter material 10 inside the range hood body 1 needs cleaning after a long period of use, first open the sealing cover 18, then pull out the support plate 5 from the exhaust port 2, and then remove all the filter materials 10. Then, rotate the positioning ring 8 with the hinge 14 to disengage the positioning ring 8 from the positioning rod 12, and then remove the rubber plate 11. This makes it easier to remove and clean individual filter materials 10.

[0030] Example 2: Based on Example 1, a support plate 5 is provided to facilitate the removal of the filter material 10. The support plate 5 has a T-shaped plate structure. The support plate 5 is placed in the moving groove 3, and one end of the support plate 5 is inserted into the limiting groove 4. A pull plate 17 is provided on the surface of the support plate 5. A sealing cover 18 is provided on the side of the smoke exhaust port 2. The sealing cover 18 covers the end face of the smoke exhaust port 2. Multiple sets of positioning plates 6 are provided. The multiple sets of positioning plates 6 are linearly arranged at equal intervals about the surface of the support plate 5. The positioning plates 6 are fixedly connected to the surface of the support plate 5.

[0031] When the filter material 10 needs to be removed during use, the sealing cover 18 can be removed first, and then the support plate 5 can be directly pulled out from the moving groove 3, so that multiple sets of filter materials 10 can be taken out from the exhaust port 2, which is convenient for subsequent cleaning of the filter material 10.

[0032] Example 3: Based on Example 2, a positioning plate 6 is provided to facilitate the installation of the filter material 10. A limiting block 13 is provided on the surface of the positioning slot 7. The limiting block 13 has a square plate structure and two sets of limiting blocks 13 are provided. The two sets of limiting blocks 13 are symmetrically distributed about the center line of the long side of the surface of the positioning slot 7. The positioning ring 8 is fixedly connected to the side of the positioning plate 6 by a hinge 14. The positioning ring 8 is sleeved on the positioning rod 12. The rubber plate 11 is inserted into the positioning slot 7. A fixing groove 15 is opened on the side of the rubber plate 11. The limiting block 13 is inserted into the fixing groove 15. Two sets of fixing grooves 15 are opened and symmetrically distributed about the rubber plate 11. The positioning rod 12 is fixedly connected to the side of the filter frame 9.

[0033] In use, the rubber plate 11 can be inserted into the positioning slot 7 first, and then the limiting block 13 can be inserted into the fixing slot 15 to avoid the rubber plate 11 from shifting in the positioning slot 7. Then, the positioning ring 8 is rotated with the hinge 14. First, the filter frame 9 is pressed down to squeeze the rubber plate 11, so that the positioning ring 8 can be fitted onto the positioning rod 12. This can then be used with the positioning slot 7 to fix the filter frame 9. The upward force of the rubber plate 11 can prevent the positioning ring 8 from coming off the positioning rod 12, thus improving the installation stability of the filter frame 9.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
