[0002] With the continuous development of society and the continuous progress of science, plate-type smoke exhaust vents have gradually entered thousands of households. Plate-type smoke exhaust vents are generally installed in walkways or smoke-proof antechambers. The smoke exhaust vents of the smoke exhaust system in windowless rooms can be suspended on the ceiling or installed on the side wall. During daily use, oil smoke constantly adheres to the surface of the plate-type smoke exhaust vent. As time accumulates, the smoke exhaust vent begins to turn black, affecting not only the appearance but also the hygiene and people's health. Therefore, it is necessary to clean it regularly. For example, the prior art (authorization announcement number CN213778012U) discloses a smoke exhaust vent that is easy to clean. It adopts a split structure of inner and outer frames, and the sealing plate is installed in the inner frame, which is easy to remove for cleaning. The structure is simple and cleaning is more convenient.

[0003] Based on the existing technology, it is found that although the smoke exhaust port adopts a split design, during the smoke exhaust process, both the inner frame and the outer frame will come into contact with the passing oil smoke. Therefore, when it is disassembled for cleaning, the outer frame still needs to be deeply cleaned, affecting the overall cleaning efficiency. Therefore, the utility model proposes a smoke exhaust port that is easy to clean to solve the problems existing in the existing technology. Utility Model Content

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] according to Figure 1-Figure 5 As shown, this embodiment proposes a smoke exhaust port that is easy to clean, including an outer frame 1. The cross-section of the outer frame 1 is rectangular. An inner frame 2 is provided on the inner side of the outer frame 1, and the shape of the inner frame 2 is adapted to the outer frame 1. The outer side surface of the inner frame 2 contacts the inner side surface of the outer frame 1. When the smoke exhaust port is in use, the outer frame 1 is first connected to the corresponding position on the wall, and then the inner frame 2 is connected.

[0022] A panel 3 is installed at one end of the inner frame 2. The length and width of the panel 3 are greater than those of the outer frame 1. In this embodiment, the panel 3 and the inner frame 2 are designed as an integral whole. Figure 5 As shown, the panel 3 is designed to shield the end of the inner frame 2, thereby improving the overall aesthetics of the smoke exhaust vent. An annular plate 18 is installed on the inner side of the inner frame 2, which provides a channel for installing external equipment, such as exhaust fans, blades, and other components.

[0023] The inner side of the panel 3 is provided with a limit cavity 4, and the outer frame 1 is provided with a locking assembly. The locking assembly and the limit cavity 4 are provided with several groups, and the position of the locking assembly corresponds to the limit cavity 4, such as Figure 3As shown, the locking assembly includes a mounting cavity 6, which is provided on the outer frame 1 and communicates with the outside. A fixing ring 7 is installed inside the mounting cavity 6, and an extension column 8 is provided inside the fixing ring 7. The extension column 8 can move vertically within the mounting cavity 6, that is, the fixing ring 7 and the extension column 8 are connected in a sliding manner, with the fixing ring 7 acting as a first limiter. A clamping block 9 is installed at one end of the extension column 8, and one end of the clamping block 9 is located in the limit cavity 4. A push block 10 is installed at the other end of the extension column 8. The extension column 8 is connected to the outer frame 1 via a first spring 19. During operation, the first spring 19 applies a thrust to the extension column 8, thereby forcing the clamping block 9 to contact the limit cavity 4. Specifically, a latch is installed on the latch block 9, and a latch hole is provided on the outer frame 1 at the corresponding position. At this time, the latch is located in the latch hole, thereby the locking assembly serves to limit and fix the panel 3. When disassembly is required, a person manually pushes the push block 10, which moves the locking block 9, thereby disengaging the latch pin from the latch hole. The panel 3 is now unlocked. Specifically, the outer frame 1 is provided with stop openings 11, the number of which corresponds to the number of the stop cavities 4, and the stop openings 11 are connected to the stop cavities 4. One end of the push block 10 passes through the stop opening 11 and can move inside the stop opening 11.

[0024] The other end of the inner frame 2 passes through the inner cavity of the outer frame 1 and is installed with a limit assembly, which contacts the end of the outer frame 1. Figure 1 and Figure 2 As shown, the limiter assembly includes two sets of symmetrically arranged mounting openings 12. A baffle 14 is mounted on the inner side of the mounting opening 12 via a hinge shaft 13. A coil spring is mounted on the hinge shaft 13, and one end of the coil spring is connected to the baffle 14. The baffle 14 contacts the end of the outer frame 1. Under the action of the coil spring, after the baffle 14 passes through the outer frame 1, it is perpendicular to the inner frame 2. Therefore, a clamping state is formed between the baffle 14 and the panel 3 with respect to the outer frame 1, thereby strengthening the connection between the inner frame 2 and the outer frame 1 and improving stability. During disassembly, the coil spring allows the angle between the baffle 14 and the inner frame 2 to be adaptively adjusted in response to external forces, thereby not affecting the installation and removal of the inner frame 2.

[0025] The outer frame 1 is provided with mounting slots 5, which are arranged in several groups. In this embodiment, two symmetrical groups of mounting slots 5 are provided. These slots 5 are open to the outside world, and an elastic assembly is mounted inside the mounting slots 5, contacting the panel 3. When the inner frame 2 is installed, the panel 3 covers the mounting slots 5. Furthermore, the elastic assembly includes contact plates 15, which are connected to the outer frame 1 via second springs 16. The second springs 16 are arranged in several groups. In this embodiment, each group of contact plates 15 has two corresponding groups of second springs 16. The outer frame 1 is provided with retaining slots 17, the number and position of which correspond to the contact plates 15. One end of the contact plate 15 is positioned within the retaining slot 17, and a portion of the contact plate 15 is also positioned within the mounting slot 5. Therefore, the contact plate 15 also acts as a position limiter for the panel 3. When the inner frame 2 is unlocked, the second springs 16 apply a certain amount of force to the panel 3 through the contact plate 15, making it easier for the operator to manually pull the panel 3.

[0026] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
