[0012] Compared with the prior art, this utility model provides a ceiling-mounted air purification device that can be quickly assembled and disassembled, and has the following beneficial effects:

[0013] This quick-assembly and disassembly ceiling-mounted air purifier cleverly achieves transmission direction conversion through a combination of driven bevel gears, active bevel gears, and a drive shaft in its fastening mechanism. The fastening mechanism, through the cooperation of a rotating rod, gears, and tooth grooves, converts the rotational motion of the knob into the linear sliding motion of the fastening plate, enabling rapid engagement and disengagement of the fastening plate and the fastening groove. The entire process requires no complex tools; operation can be completed simply by turning the knob. Even non-professionals can easily master it. This design significantly shortens the installation and disassembly time of the air purifier, improves work efficiency, reduces reliance on professional installers, and reduces labor costs. Two symmetrically arranged fastening mechanisms apply force simultaneously from both ends of the air purifier, ensuring even force distribution and preventing loosening or detachment. The limiting mechanism, through spring-driven contact between the limiting plate and the outer wall of the knob, prevents accidental knob rotation that could loosen the fastening plate, further ensuring stability and guaranteeing the safe and stable installation of the air purifier on the ceiling.

[0019] 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.

[0020] Please see Figure 1-4A ceiling-mounted air purifier that can be quickly disassembled and assembled includes an air purifier body 1, a square steel 2, a ceiling panel 3, and a fastening mechanism. The ceiling panel 3 has a mounting groove 4 on its bottom wall, and the square steel 2 is mounted on one end of the top wall of the ceiling panel 3. The fastening mechanism includes a cavity 5, a rotating rod 6, a movable groove 7, a fastening plate 8, and a fastening groove 9. The air purifier body 1 has a cavity 5 at one end, and the rotating rod 6 is rotatably mounted within the cavity 5. Gears 10 are mounted at both ends of the rotating rod 6. Two sets of movable grooves 7 are symmetrically formed on one side wall of the air purifier body 1, and fastening plates 8 are slidably mounted within the movable grooves 7. Each set of fastening plates 8 has a toothed groove 11 on its bottom wall, and the toothed groove 11 meshes with the gear 10. The side wall of the square steel 2... Two sets of fastening grooves 9 are symmetrically provided. The fastening plate 8 is adapted to the fastening grooves 9. A groove 12 is provided at one end of the bottom wall of the air purifier body 1. A knob 13 is installed on the rotating rod 6 through a transmission mechanism. A limit mechanism is installed on the outer wall of the knob 13. Two sets of fastening mechanisms are provided and symmetrically arranged at the left and right ends of the air purifier body 1. In this embodiment, the ceiling panel 3 is installed and fixed by workers in advance, and an installation groove 4 adapted to the air purifier body 1 is provided to ensure that the square steel 2 at both ends of its top wall is installed firmly. A power cord is reserved inside the ceiling panel 3. After connecting the air purifier body 1 to the reserved power cord, the air purifier body 1 is aligned with the installation groove 4 on the bottom wall of the ceiling panel 3 and placed in the installation groove 4. Position the air purifier body 1. Then, rotate the two sets of knobs 13 located in the grooves 12 on the bottom wall of the air purifier body 1. These knobs 13, through a transmission mechanism, drive the rotating rod 6 within the cavity 5 to rotate. As the rotating rod 6 rotates, the gears 10 at its front and rear ends rotate accordingly. Since the gears 10 mesh with the toothed grooves 11 on the bottom wall of the fastening plate 8, the rotation of the gears 10 causes the two sets of fastening plates 8 to slide outwards within the movable grooves 7. As the fastening plates 8 slide, their ends gradually extend beyond the side wall of the air purifier body 1 and eventually engage with the corresponding fastening grooves 9 on the side wall of the square steel 2. Once the fastening plates 8 are fully engaged and locked into the fastening grooves 9, the limiting mechanism on the outer wall of the knobs 13 limits and fixes the knobs 13, preventing accidental rotation of the rotating rod 6 and loosening of the fastening plates 8. With this, the installation of the air purifier body 1 is complete. When maintenance or replacement of the air purifier body 1 is required, first release the limiting mechanism from limiting the knob 13. Then, rotate both sets of knobs 13 in opposite directions. The two sets of knobs 13 drive the rotating rod 6 to rotate in opposite directions through the transmission mechanism. The gear 10 also rotates in opposite directions, and under the meshing of the tooth groove 11, it drives the fastening plate 8 to slide inward in the movable groove 7, so that the fastening plate 8 gradually exits from the fastening groove 9 of the square steel 2. When the fastening plate 8 is completely separated from the fastening groove 9, the air purifier body 1 can be removed from the mounting groove 4 of the ceiling panel 3, completing the disassembly. The entire installation and disassembly process is mainly achieved by rotating the knob 13 to achieve the engagement and disengagement of the fastening plate 8 and the fastening groove 9, without the need for complicated tools.The operation steps are simple and easy to understand, even non-professionals can quickly master them, greatly saving installation and disassembly time and improving work efficiency.

[0021] Preferably, in this embodiment, the transmission mechanism includes a driven bevel gear 14, a driving bevel gear 15, and a drive shaft 16. The driven bevel gear 14 is sleeved on the outer wall of the middle part of the rotating rod 6. The bottom end of the driven bevel gear 14 meshes with the driving bevel gear 15. The bottom end of the driving bevel gear 15 is installed with the drive shaft 16. The bottom wall of the drive shaft 16 passes through the groove 12 and is fixedly connected to the top wall of the knob 13. When it is necessary to control the rotation of the rotating rod 6 by the knob 13, the operator manually rotates the knob 13 located in the groove 12 on the bottom wall of the air purifier body 1. Since the top wall of the knob 13 is fixedly connected to the bottom wall of the drive shaft 16, the rotation of the knob 13 will directly drive the drive shaft 16 to rotate synchronously. The top end of the drive shaft 16 is equipped with the driving bevel gear 15. As the drive shaft 16 rotates, the driving bevel gear 15... 5 will also rotate accordingly. The active bevel tooth 15 and the driven bevel tooth 14 sleeved on the outer wall of the rotating rod 6 are in a meshing connection state. The active bevel tooth 15 and the driven bevel tooth 14 are in the vertical and horizontal directions respectively, forming a 90-degree transmission angle. Under the rotation of the active bevel tooth 15, the driven bevel tooth 14 meshing with it will be subjected to force and thus rotate. Because the driven bevel tooth 14 is sleeved on the outer wall of the rotating rod 6 and the two are relatively fixed, the rotation of the driven bevel tooth 14 will drive the rotating rod 6 to rotate synchronously in the cavity 5. Gears 10 are installed at both the front and rear ends of the rotating rod 6. The rotation of the rotating rod 6 will drive the gears 10 to rotate together. Finally, through the meshing of the gears 10 with the tooth grooves 11 on the bottom wall of the fastening plate 8, the fastening plate 8 is slidable, completing the fastening or separation operation of the air purifier body 1 and the square steel 2.

[0022] Preferably, in this embodiment, the limiting mechanism includes a limiting box 17, a spring 18, a movable plate 19, a limiting plate 20, a sliding groove 21, and a lever 22. The limiting box 17 is installed in the groove 12. The movable plate 19 is slidably installed inside the limiting box 17. Two sets of springs 18 supporting the movable plate 19 are installed inside the limiting box 17. The limiting plate 20 is installed at the end of the movable plate 19 away from the springs 18. The limiting plate 20 penetrates the side wall of the limiting box 17 and is adapted to the outer wall of the knob 13. The sliding groove 21 is formed in the bottom wall of the limiting box 17. The lever 22 is slidably installed in the sliding groove 21. The lever 22 is fixedly connected to the movable plate 19. Under the natural extension of the spring 18, the spring 18 will apply an directional force to the movable plate 19. The thrust in the direction of knob 13 causes the movable plate 19, which is slidably mounted inside the limiting box 17, to slide along the side wall of the limiting box 17 toward the knob 13 and come into contact with the outer wall of the knob 13, thus achieving a limiting effect. When it is necessary to release the limiting effect on the knob 13, the operator can move the lever 22 located in the slide groove 21 on the bottom wall of the limiting box 17. Since the top wall of the lever 22 is fixedly connected to the bottom wall of the movable plate 19, moving the lever 22 will cause the movable plate 19 to overcome the elastic force of the spring 18 and slide away from the knob 13 along the limiting box 17. At this time, the limiting plate 20 will move together with the movable plate 19, gradually detach from the outer wall of the knob 13 and retract into the limiting box 17, and the knob 13 will return to a rotatable state, and the limiting effect will be released.

[0023] Preferably, in this embodiment, a protective shell 23 is fitted into each set of grooves 12. The protective shell 23 can cover the mechanical structure knob 13 and limiting mechanism in the groove 12, so that the bottom wall of the air purifier body 1 remains flat and beautiful, which is more coordinated with the decoration style of the ceiling environment and enhances the overall visual effect.

[0024] Preferably, in this embodiment, a limiting block 24 is installed at the end of each fastening plate 8 away from the fastening groove 9. The limiting block 24 prevents the fastening plate 8 from moving excessively, avoids complete separation of the meshing structure between the two, reduces the risk of misalignment and impact, protects the integrity of the teeth of the gear 10 and the fastening plate 8, and extends the service life of the core transmission components.

[0025] Preferably, in this embodiment, a shock-absorbing pad is installed on the outer wall of the fastening plate 8 near the fastening groove 9. When the air purifier is running, the fan will vibrate. If there is a gap between the fastening plate 8 and the fastening groove 9, the vibration will be transmitted to the contact part of the two and cause resonance noise. The elastic material of the shock-absorbing pad can absorb the vibration energy, block the noise transmission path, and avoid the abnormal noise generated by direct friction between metals, making the device operate more quietly.

[0026] Preferably, in this embodiment, the shock-absorbing pad is made of silicone material and its surface is provided with an anti-slip raised structure. The elasticity of the silicone itself can absorb vibration energy, and the anti-slip raised structure can disperse the vibration to multiple raised units by increasing the number of contact points with the fastening groove 9. The vibration energy is consumed by multiple points of deformation, thereby improving the overall shock absorption efficiency.

[0027] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0028] 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.
