Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically a self-cleaning heating and ventilation device. Background Technology

[0002] Dust accumulation inside heating ventilation ducts can reduce the effective ventilation cross-sectional area and increase airflow resistance, affecting ventilation efficiency; it can also form an insulation layer that hinders heat transfer and reduces heating effect; it can provide conditions for the growth of bacteria and microorganisms, threatening human health; it can absorb odors and emit unpleasant smells due to microbial decay; and it can also enter the wear parts of ventilation equipment, increasing energy consumption, shortening service life, and even causing equipment failure.

[0003] Existing ventilation equipment typically has dust interception devices at the inlet. Regular maintenance of these dust interception devices can prevent dust from entering the duct. However, if the dust interception devices are not maintained properly or in a timely manner, dust will adhere to the inner wall of the duct. Cleaning the duct requires disassembling it. Existing technologies also exist that can clean the dust inside the duct without disassembling it. However, during the cleaning process, the dust that was originally attached to the inner wall of the duct will be stirred up again. This stirred-up dust will leak out from the air outlet with the airflow. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning heating and ventilation device to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning heating and ventilation device, comprising a ventilation pipe, a grid mesh inside the ventilation pipe, a cleaning plate slidably connected to the inner side of the ventilation pipe, a ventilation opening and an interception opening on the inner side of the cleaning plate, a filter cloth inside the interception opening, a plurality of small air holes on the inner side of the filter cloth, a transmission rod rotatably connected to the inner side of the ventilation pipe, and a camshaft fixedly installed on the outer surface of the transmission rod.

[0006] Preferably, a load-bearing frame is fixedly installed on the outer surface of the ventilation duct, and a drive motor is fixedly installed on the outer surface of the load-bearing frame. The output end of the drive motor is fixedly installed on the outer surface of the drive rod.

[0007] Preferably, a sliding frame is fixedly installed on the inner wall of the ventilation duct, the inner wall of the sliding frame is slidably connected to the outer surface of the grille, and a force-bearing plate is fixedly installed on the outer surface of the grille, the outer surface of the force-bearing plate is in close contact with the outer surface of the camshaft.

[0008] Preferably, a fixing seat is fixedly installed on the outer surface of the sliding frame, and a sliding rod is fixedly installed on the outer surface of the fixing seat. The outer surface of the sliding rod is slidably connected to the inner wall of the grid.

[0009] Preferably, a spring is sleeved on the outer surface of the slide rod, one end of the spring is fixedly installed to the outer surface of the fixed base, and the other end of the spring is fixedly installed to the outer surface of the grid mesh.

[0010] Preferably, a servo motor is fixedly installed on the outer surface of the load-bearing frame, the output end of the servo motor is fixedly installed on the outer surface of the cleaning plate, and a bearing frame is fixedly installed on the outer surface of the load-bearing frame, the outer surface of the bearing frame and the outer surface of the cleaning plate are rotatably connected.

[0011] Preferably, the cleaning plate has a limiting groove on the outer surface of the interception port, and a limiting ring is fixedly installed on the outer surface of the filter cloth. The outer surface of the limiting ring and the inner wall of the limiting groove are slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes the coordination between the ventilation duct, grille, cleaning plate, interception port, filter cloth, and camshaft. When the dust interception device at the air inlet is not properly maintained or is not timely, dust entering the duct will be intercepted by the grille. When the grille needs to be cleaned, the cleaning plate can be rotated, allowing it to drive the interception port into the duct. Then, the camshaft can be rotated, and the high-speed rotation of the camshaft can vibrate the grille. The dust intercepted on the grille will fall off due to the vibration and re-enter the filter cloth in the interception port with the air, where it will be captured by the filter cloth. Afterward, the rotation of the camshaft can be stopped, stopping the grille. The cleaning plate can then be reset, allowing the filter cloth to carry the intercepted dust out of the duct. The ventilation port will then be aligned with the duct again, allowing the air inside the duct to circulate normally, thus solving the problem of dust being leaked from the air outlet with the airflow.

[0014] 2. This application utilizes the cooperation between the spring, the grid mesh, and the camshaft. The spring can continuously push the grid mesh. When the grid mesh is pushed by the camshaft, the grid mesh will move towards the spring and squeeze the spring. When the camshaft moves away from the grid mesh, the spring can push the grid mesh to quickly return to its original position. This cycle repeats, allowing the grid mesh to vibrate rapidly.

Detailed Implementation

[0021] 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.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for a self-cleaning heating and ventilation device, including a ventilation pipe 1, a grid mesh 2 inside the ventilation pipe 1, a cleaning plate 3 slidably connected to the inner side of the ventilation pipe 1, an air inlet 4 and an interception port 5 on the inner side of the cleaning plate 3, a filter cloth 6 inside the interception port 5, and multiple small air holes on the inner side of the filter cloth 6, a transmission rod 7 rotatably connected to the inner side of the ventilation pipe 1, and a camshaft 8 fixedly installed on the outer surface of the transmission rod 7. When the dust interception device at the air inlet is not properly maintained or not timely, dust entering the pipe will be intercepted by the grid mesh 2. When it is necessary to clean the grid mesh 2, the cleaning plate 3 can be rotated to allow the dust to pass through. The cleaning plate 3 can drive the interception port 5 into the pipe, and then the camshaft 8 can be rotated. The high-speed rotating camshaft 8 can vibrate the grid screen 2. The dust intercepted on the grid screen 2 will fall off due to the vibration and re-enter the filter cloth 6 in the interception port 5 with the air. Finally, it will be captured by the filter cloth 6. Then the rotation of the camshaft 8 can be stopped, so that the grid screen 2 stops. After that, the cleaning plate 3 can be reset. The reset cleaning plate 3 can drive the filter cloth 6 to carry the intercepted dust out of the pipe, and the vent 4 will be aligned with the pipe again, so that the air in the pipe can flow normally, thereby solving the problem that the raised dust will leak out from the air outlet with the airflow.

[0023] A load-bearing frame 9 is fixedly installed on the outer surface of the ventilation duct 1, and a drive motor 10 is fixedly installed on the outer surface of the load-bearing frame 9. The output end of the drive motor 10 is fixedly installed on the outer surface of the drive rod 7. The load-bearing frame 9 can provide necessary support and load-bearing functions for the ventilation duct 1 and the drive motor 10. When cleaning is required, the drive motor 10 can drive the camshaft 8 to rotate quickly through the drive rod 7. At the same time, a bearing is installed inside the ventilation duct 1, and the bearing is sleeved on the outer surface of the drive rod 7, making the drive rod 7 more flexible when rotating.

[0024] A sliding frame 11 is fixedly installed on the inner wall of the ventilation duct 1 and the grille 2. The inner wall of the sliding frame 11 is slidably connected to the outer surface of the grille 2. A force-bearing plate 12 is fixedly installed on the outer surface of the grille 2. The outer surface of the force-bearing plate 12 is in contact with the outer surface of the camshaft 8. When the camshaft 8 rotates, it will continuously impact the force-bearing plate 12, thereby driving the grille 2 to move through the force-bearing plate 12. When the grille 2 moves, it can slide on the inner wall of the sliding frame 11.

[0025] A fixed seat 13 is fixedly installed on the outer surface of the slide frame 11, and a slide rod 14 is fixedly installed on the outer surface of the fixed seat 13. The outer surface of the slide rod 14 is slidably connected to the inner wall of the grid mesh 2. The slide frame 11 can provide necessary support for the slide rod 14 through the fixed seat 13. When the grid mesh 2 is impacted by the camshaft 8, it can move in the direction given by the slide rod 14 to reduce the possibility of the grid mesh 2 tilting or falling off during movement.

[0026] A spring 15 is sleeved on the outer surface of the slide rod 14. One end of the spring 15 is fixedly installed on the outer surface of the fixed base 13, and the other end of the spring 15 is fixedly installed on the outer surface of the grid mesh 2. The spring 15 can always push the grid mesh 2. When the grid mesh 2 is pushed by the camshaft 8, the grid mesh 2 will move towards the spring 15 and squeeze the spring 15. When the camshaft 8 moves away from the grid mesh 2, the spring 15 can push the grid mesh 2 to quickly return to its original position. This cycle repeats, allowing the grid mesh 2 to vibrate rapidly.

[0027] A servo motor 16 is fixedly installed on the outer surface of the load-bearing frame 9. The output end of the servo motor 16 is fixedly installed on the outer surface of the cleaning plate 3. A bearing frame 17 is fixedly installed on the outer surface of the load-bearing frame 9. The outer surface of the bearing frame 17 is rotatably connected to the outer surface of the cleaning plate 3. The load-bearing frame 9 can provide support for the servo motor 16. The servo motor 16 can drive the cleaning plate 3 to rotate precisely by a fixed degree, thereby enabling the ventilation port 4 or interception port 5 on the cleaning plate 3 to be precisely aligned with the pipe.

[0028] The cleaning plate 3 has a limiting groove 18 on the outer surface of the interception port 5. A limiting ring 19 is fixedly installed on the outer surface of the filter cloth 6. The outer surface of the limiting ring 19 is slidably connected to the inner wall of the limiting groove 18. When the filter cloth 6 needs to be replaced, the limiting ring 19 can be picked up from the limiting groove 18. The limiting ring 19 can drive the filter cloth 6 to fall off the interception port 5. During use, the airflow will continuously impact the filter cloth 6, and the limiting ring 19 can be locked on the limiting groove 18, so that the filter cloth 6 will not be pushed into the depth of the pipe by the airflow.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
