[0020] 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.

[0021] Please see Figures 1-4An air purification device for a kitchen includes a housing 1, a fan 2, an output component, and a filter component. The fan 2 is disposed inside the housing 1. The output component includes a plastic cover 3 and a protective frame 4. The plastic cover 3 is inserted into the housing 1, and the protective frame 4 is also embedded inside the plastic cover 3. A through hole is provided at the other end of the housing 1. The filter component is embedded in the bottom wall of the housing 1. The filter component includes a insertion frame 5, a filter frame 6, and a positioning element. The insertion frame 5 is inserted into the housing 1 at the top, and the filter frame 6 is embedded inside the insertion frame 5. The positioning element connected to the housing 1 is also provided on the bottom wall of the insertion frame 5.

[0022] The hood 3 is flared and plugged into the housing 1, with the opening facing outward to increase the exhaust area. When the fan 2 is started, kitchen air enters the housing 1 under negative pressure, is filtered by the filter assembly, and is then discharged outward through the protective frame 4. The protective frame 4 is used to prevent insects and birds from entering the hood 3.

[0023] The fan 2 (centrifugal or axial) inside the housing 1 generates negative pressure, which draws in the pre-filtered air through the through hole at the other end of the housing 1. The air is then purified by the filter assembly inside the housing 1. When the air passes through the filter frame 6 in the insert frame 5, the HEPA filter (filtration accuracy 0.3μm) adsorbs fine particulate matter, and the activated carbon filter removes odors and harmful gases. Finally, the purified air is discharged outdoors from the other side of the housing 1 or circulated to the kitchen.

[0024] The insert frame 5 is connected to the housing 1 via a positioning component, facilitating assembly and disassembly.

[0025] In actual use, the positioning component includes a handle 7, a worm gear 8, a worm 9, a screw 10, and a positioning block 11. The bottom wall of the insertion frame 5 is provided with a movable groove, in which the worm gear 8 and the worm 9 are arranged. The worm 9 meshes with the worm gear 8 and passes through the insertion frame 5 and is connected to the handle 7. Screws 10 are symmetrically arranged on the left and right sides of the worm gear 8. The left and right sides of the insertion frame 5 are also provided with storage grooves, in which the positioning block 11 is arranged. The screw 10 extends into the storage groove and is threadedly connected to the positioning block 11. The inner wall of the housing 1 is also provided with a slot that matches the positioning block 11. Rotating the handle 7 drives the worm 9 to rotate, and the worm 9 meshes with the worm gear 8 to make it rotate. Since the screws 10 are symmetrically arranged on the left and right sides of the worm gear 8, when the worm gear 8 rotates, it drives the screws 10 to move laterally in the storage groove, thereby driving the positioning block 11 to extend and retract. When the 3rd hand is rotated 180° clockwise, the positioning block 11 is fully inserted into the slot on the inner wall of the housing 1, the insertion frame 5 is fixed to the housing 1, and the first rounded end 13 of the positioning block 11 ensures smooth insertion and avoids jamming.

[0026] Rotate the handle counterclockwise 7180°, the positioning block 11 retracts into the storage slot, and the insertion frame 5 separates from the housing 1. At this point, the filter assembly can be directly removed for cleaning or replacement.

[0027] The silicone friction block 12 (Shore hardness 60A) on the handle 7 increases grip friction, allowing the handle 7 to rotate stably even when hands are oily.

[0028] In this embodiment, two sets of second rounded corners 14 are provided at both ends of the top wall of the insertion frame 5 to facilitate stable insertion of the insertion frame 5 into the housing 1.

[0029] The auxiliary block 15 below the handle 7 can be used in conjunction with the "LOCK" and "UNLOCK" markings on the bottom wall of the housing 1 to visually determine the locking status of the filter assembly.

[0030] In this document, the term "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The term "embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment, nor does it specifically limit its independence or connection with other embodiments. In principle, in this application, as long as there are no technical contradictions or conflicts, the technical features mentioned in each embodiment can be combined in any way to form corresponding implementable technical solutions.

[0031] Unless otherwise defined, the technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the use of related terms herein is merely for the purpose of describing particular embodiments and is not intended to limit this application.

[0032] 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.
