Description

Technical Field

[0001] The utility model relates to the technical field of air filter protection, in particular to a protective device for an air filter. Background Art

[0002] An air filter is a device used to remove impurities and pollutants from the air. It is commonly used in various application scenarios, including home, commercial and industrial environments. Its main function is to filter the air by physical or chemical methods to improve air quality and protect people's health.

[0003] When existing equipment is in use, it will only be turned on when the air quality deteriorates or the harmful substances in the air exceed a certain threshold. When not in use, there are no protective measures, resulting in some dirt and debris floating in the air entering the equipment. The air inlet may also be damaged due to some accidental impacts, and the filter inside the equipment needs to be frequently removed for cleaning, increasing labor costs. Utility Model Content

[0032] Example

[0033] Reference Figure 1-4The utility model provides a technical solution: a protective device for an air filter, comprising a body 1, two protective mechanisms, the protective mechanism comprising a rotating rod 2, a protective plate 3, a first gear 4 and a second gear 5, the rotating rod 2 is rotatably mounted on the surface of the body 1 through a bearing, the protective plate 3 is fixedly mounted on the surface of the rotating rod 2, the first gear 4 is fixedly mounted on the top of the rotating rod 2, the second gear 5 is rotatably mounted on the top of the body 1, the second gear 5 is meshed with the first gear 4, the collecting mechanism is arranged inside the body 1, a supporting frame 17 is fixedly mounted on the top of the body 1, a motor 18 is fixedly mounted on the bottom of the inner wall of the supporting frame 17, and a motor 18 is fixedly mounted on the output end of the motor 18 A transmission toothed belt 20 is sleeved between the driven gear 19 and the two transmission gears 8. By setting a protective mechanism, when the body 1 is not in use, the motor 18 is started to drive the driven gear 19 to rotate. Since the driven gear 19 and the transmission gear 8 are meshed and connected with the transmission toothed belt 20, the transmission toothed belt 20 drives the two transmission gears 8 to rotate at the same time. Through the meshing connection between the first gear 4 and the second gear 5, the first gear 4 drives the rotating rod 2 and the protective plate 3 to rotate. When the first gear 4 drives the rotating rod 2 and the protective plate 3 to rotate 270 degrees, the air inlet of the body 1 is closed, thereby solving the problem that the body 1 is easily damaged without protective measures when it is not in use;

[0034] Reference Figure 1-4The collecting mechanism comprises a tray 6 and a positioning rod 7. The tray 6 is slidably mounted inside the body 1. The positioning rod 7 is rotatably mounted on the front side of the tray 6. A transmission gear 8 is fixedly mounted on the top of the two second gears 5. A turntable 9 is fixedly mounted on the top of the transmission gear 8. A transmission shaft 10 is fixedly mounted on the top of the turntable 9. Two support blocks 11 are fixedly mounted on the top of the body 1. A connecting rod 12 is slidably sleeved inside the two support blocks 11. An impact head 13 is fixedly mounted on the rear side of the connecting rod 12. A transmission frame 14 is fixedly mounted on the front side of the connecting rod 12. A transmission groove 15 is opened on the top of the transmission frame 14. The transmission groove 15 is sleeved on the surface of the transmission shaft 10. A vibration block 16 is fixedly mounted on the top of the body 1. The shape of the front side of the vibration block 16 matches the impact head 13. By setting the collecting mechanism When the transmission gear 8 rotates, it drives the turntable 9 and the transmission shaft 10 to rotate, causing extrusion on the inner wall of the transmission groove 15. Through the cooperation of the support block 11, the connecting rod 12 drives the transmission frame 14 and the impact head 13 to move forward away from the vibration block 16. When the protective plate 3 closes the air inlet of the main body 1, the transmission gear 8 drives the second gear 5 and the turntable 9 to continue to rotate. Since the first gear 4 is a residual gear, the second gear 5 no longer drives the first gear 4 to rotate. At this time, since the transmission frame 14 drives the connecting rod 12 and the impact head 13 to reciprocate, the impact head 13 begins to intermittently impact the vibration block 16. Since the vibration block 16 is connected to the main body 1, the dust on the surface of the filter screen inside the main body 1 is shaken off and falls into the inside of the tray 6, so that people do not need to frequently remove the filter screen for cleaning.

[0035] Specifically, the working process or working principle of the protective device of the air filter is as follows: when in use, when the main body 1 is not in use, the motor 18 is started to drive the driven gear 19 to rotate. Since the driven gear 19 and the transmission gear 8 are both meshed and connected with the transmission belt 20, the transmission belt 20 drives the two transmission gears 8 to rotate at the same time. Through the meshing connection of the first gear 4 and the second gear 5, the first gear 4 drives the rotating rod 2 and the protective plate 3 to rotate. When the first gear 4 drives the rotating rod 2 and the protective plate 3 to rotate 270 degrees, the air inlet of the main body 1 is closed. When the transmission gear 8 rotates, it drives the rotating disk 9 and the transmission shaft 10 to rotate, and the transmission slot 1 5 is squeezed, and through the cooperation of the support block 11, the connecting rod 12 drives the transmission frame 14 and the impact head 13 to move forward away from the vibration block 16. When the protective plate 3 closes the air inlet of the main body 1, the transmission gear 8 drives the second gear 5 and the turntable 9 to continue to rotate, and since the first gear 4 is a residual gear, the second gear 5 no longer drives the first gear 4 to rotate. At this time, since the transmission frame 14 drives the connecting rod 12 and the impact head 13 to reciprocate, the impact head 13 begins to intermittently impact the vibration block 16. Since the vibration block 16 is connected to the main body 1, the dust on the surface of the filter screen inside the main body 1 is shaken off and falls into the inside of the tray 6.

[0036] It should be noted that the main body 1 and the motor 18 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
