[0025] The dustproof mechanism 6 includes a guide rail 61, which is fixedly installed on the top of the housing 1 near the dustproof net 7. A guide slider 62 is slidably connected inside the guide rail 61. A drive motor 63 is fixedly connected to the front end of the guide rail 61. A lead screw 64 is fixedly installed through the guide rail 61 at the output end of the drive motor 63. The lead screw 64 is rotatably connected inside the guide rail 61. The lead screw 64 and the guide slider 62 are threadedly connected. A cleaning brush assembly 65 is fixedly installed on the top of the guide slider 62. The cleaning brush assembly 65 is fitted to the outer side of the dustproof net 7. The housing 1 and the bottom cover 2 are bolted together for easy disassembly and assembly, facilitating maintenance and cleaning of the internal hot air blower 3. The design of the reserved circular groove 4 allows for… The output end of the hot air blower 3 is properly exposed to ensure normal hot air output. The dustproof net 7 inside the air inlet slot 5 can effectively block dust from entering the housing 1, protecting the hot air blower 3 and other electronic components. The dustproof mechanism 6 further improves the dustproof performance. The guide rail 61 provides a stable sliding track for the guide slider 62. The drive motor 63 drives the lead screw 64 to rotate, causing the guide slider 62 to slide within the guide rail 61, thereby allowing the cleaning brush group 65 to move laterally and clean the outside of the dustproof net 7 in a close fit, avoiding dust clogging the dustproof net 7, ensuring smooth air circulation, extending the service life of the heater, and reducing the risk of failure caused by dust accumulation.

[0026] refer to Figs. 2-3 The bottom of the bottom cover 2 is fixedly installed with lamp holders 8 on both ends of the side away from the reserved circular groove 4. The bottom of the lamp holders 8 is fixedly installed with lighting and heating lamps 9. The top of the housing 1 is fixedly installed with hanging mounting brackets 10 on both sides of the middle. The hanging mounting brackets 10 have mounting holes 11 on the outer side. The mounting holes 11 are countersunk holes. The lighting and heating lamps 9 can emit heat while providing lighting, which increases the functionality of the heater and brings more convenience to users. The hanging mounting brackets 10 on both sides of the top of the housing 1 make it easy to install the heater on the ceiling. The mounting holes 11 are countersunk holes, which makes the installation more beautiful and firm, reduces the protruding parts during the installation process, and avoids possible collision damage. The overall design takes into account both functional needs and focuses on the convenience and aesthetics of installation, which improves the applicability and practicality of the ceiling heater in various environments.

[0027] refer to Figs. 1-4The output end of the hot air blower 3 is fixedly connected to an air guide tube 12, which is located inside a pre-reserved circular groove 4. A mesh 13 is fixedly connected inside the air guide tube 12. The outer corners of the bottom cover 2 and the housing 1 are rounded. The air guide tube 12 connected to the output end of the hot air blower 3 is located inside the pre-reserved circular groove 4, which can better guide the direction of hot air output, making the hot air blow more concentrated towards the required area and improving the heating effect. The mesh 13 inside the air guide tube 12 can play a blocking and protective role, preventing foreign objects from entering the interior of the hot air blower 3, ensuring the normal operation and service life of the hot air blower 3. At the same time, the outer corners of the bottom cover 2 and the housing 1 are rounded, which on the one hand increases the aesthetics of the product and makes the overall shape more streamlined; on the other hand, the rounded corners reduce the risk of injury due to accidental collisions during use, improving the safety of the product. This design fully considers practicality, safety and aesthetics, bringing a better user experience.

[0028] refer to Figs. 1-4 The cleaning brush assembly 65 includes a connecting arm 651, which is fixedly mounted on the top of the guide slider 62. The connecting arm 651 has an L-shaped overall shape. A groove 652 is provided on the inner side of the connecting arm 651. A slide plate 653 is slidably connected to the inner side of the groove 652. A brush plate 654 is fixedly connected to the inner side of the slide plate 653. The inner side of the brush plate 654 is in close contact with the dustproof mesh 7. A limit frame 655 is fixedly connected to the outer side of the upper end of the slide plate 653. A limit screw 656 is threaded to the outer end of the limit frame 655. The end of the limit screw 656 passes through the limit frame 655. The internal cross-sectional shape of both the slide plate 653 and the groove 652 is convex. The limit screw 656 is a hand-tightening screw, and its outer end is fixedly connected to an adjustment handle with anti-slip protrusions. The connecting arm 651 is L-shaped, providing a stable support structure for the brush plate 654. The cooperation between the slide groove 652 and the slide plate 653 makes the installation and removal of the brush plate 654 more convenient. When it is necessary to clean or replace the brush plate 654, the slide plate 653 can be easily slid out from the inside of the slide groove 652. The brush plate 654 is closely connected to the dustproof net 7, which can effectively clean the dustproof net 7 and prevent dust blockage. The setting of the limit bracket 655 and the limit screw 656 further ensures the stability of the slide plate 653 during use. The hand-tight screw and the adjustment handle with anti-slip protrusions make it convenient for users to operate. The position of the slide plate 653 can be quickly adjusted and fixed without the aid of tools. The overall design not only ensures the cleaning effect of the cleaning brush group 65, but also improves the convenience and stability of use.

[0029] Operating principle and advantages: By setting up the dustproof mechanism 6, the air inlet slot 5 can be effectively filtered and screened by the dustproof net 7 during actual use, thereby effectively preventing dust from entering the housing 1 with the air. The whole device has excellent dustproof performance. The drive motor 63 can be started to run. When the drive motor 63 drives the lead screw 64 to rotate, the rotation of the lead screw 64 can assist the drive guide slider 62 to slide smoothly on the inside of the guide rail 61. By driving the guide slider 62 to slide linearly inside the guide rail 61, it can assist the drive guide slider 62 to drive the cleaning brush group 65 to move laterally. At this time, the lateral movement of the cleaning brush group 65 can effectively scrape and clean the dustproof net 7 of the air inlet slot 5, greatly avoiding the phenomenon of dust clogging. The whole device exhibits strong dustproof capability, providing a strong guarantee for the stable operation and long-term use of the device.

[0030] By setting the cleaning brush assembly 65, the device can drive the guide slider 62 to move via the drive motor 63 and lead screw 64 during use. The guide slider 62 then drives the connecting arm 651 to slide, which in turn causes the brush plate 654 to tightly adhere to the dustproof mesh 7 for brushing and cleaning. This effectively prevents dust from adhering to the surface of the dustproof mesh 7. Furthermore, if the brush plate 654 is damaged during use, it can be disengaged from the connecting arm 651 by loosening the limiting screw 656. At this point, the sliding plate 653 can be easily pulled out from the inside of the slide groove 652, allowing for quick removal of the brush plate 654. After disassembly and reassembly, only... Insert the slide plate 653 into the slide groove 652, and then twist the limiting screw 656 to abut the connecting arm 651, which can then assist in the installation of the brush plate 654 for long-term use. In addition, during use, the lighting and heating lamp 9 on the lamp holder 8 can provide auxiliary lighting and heating function. The reserved circular groove 4 can expose the output end of the hot air blower 3, and hot air can be guided through the air guide tube 12. The air guide tube 12 is equipped with a partition net 13 inside, which can help block and protect the air guide tube 12, greatly improving its safety and convenience of use. The bottom cover 2 is installed with bolts, which can facilitate the disassembly and assembly of the bottom cover 2, bringing great convenience to the use of the device.
