[0026] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0028] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] like Figures 1 to 5 As shown, this embodiment proposes an air conditioning and heating ventilation duct structure, including a ventilation duct 1, and also includes two groups of filter plates 2 arranged at intervals in the ventilation duct 1, one of the filter plates 2 on the windward side is rotatably arranged in the ventilation duct 1; it also includes a rotating rod 3, which is rotatably located between the two filter plates. The rotating rod 3 can be connected to the ventilation duct 1 through a bearing 10. One end of the rotating rod 3 passes through the ventilation duct 1 and is connected to a handle 4. At least one group of support rods 5 is also provided on the rotating rod 3. The end of the support rod 5 is connected to a flapping part 6. Rotating the handle 4 makes the support rod 5 move in the fan-shaped area, so that the flapping part 6 contacts and flaps the filter plate 2.

[0030] In the prior art, a filter screen plate 2 is arranged in the ventilation duct 1 to filter dust and other impurities in the air, so as to purify the air entering the room and improve the air quality. At the same time, the filter screen can also protect the equipment inside the air conditioning system, reduce wear and pollution, thereby prolonging the service life of the equipment and maintaining the high efficiency of the system. After a long time of use, the filter screen plate 2 will be completely covered with dust and impurities, and the filtering effect and functionality will be greatly reduced, resulting in deterioration of indoor air quality, dust covering will hinder air circulation, reduce equipment operating efficiency, increase energy consumption and operating cost.

[0031] Based on the above problems, the air conditioning heating ventilation pipe structure is studied. First, two filter screen plates 2 are used to form secondary filtration, and the filtering effect is better. After a certain period of use, the filter screen plate 2 of the wind receiving surface is rotated, and the two filter screen plates 2 with dust are opposite to each other. By manually rotating the handle 4, the handle 4 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the supporting rod 5 and the beating part 6 to intermittently beat the two filter screen plates 2, so that the filter screen plate 2 vibrates and the dust and particle impurities are shaken off, thereby avoiding the long-term covering of the filter screen plate 2 by dust and impurities, causing blockage and affecting air circulation quality.

[0032] It is worth noting that, as shown in Figures 2 to 4 The distance between the rotating rod 3 and the rotatable filter screen plate 2 is greater than half the length of the filter screen plate 2, so as to avoid interference between the filter screen plate 2 and the rotating rod 3 and the supporting rod 5 during rotation.

[0033] Considering that even if the dust and impurities can be avoided from covering the filter screen plate 2 for a long time by the beating part 6, the dust and impurities shaken off between the two filter screen plates 2 will cover the filter screen plate 2 again after a certain period of use, in order to reduce the frequency of manual rotation of the handle 4 for cleaning, a dust discharge port is arranged in the ventilation duct 1, the dust discharge port is located between the two filter screen plates 2, and a dust discharge pipe 7 is fixed below the dust discharge port. The dust shaken off is discharged through the dust discharge pipe 7. Further, a cover 8 is detachably connected to the bottom of the dust discharge pipe 7, and the cover 8 is connected to the bottom of the dust discharge pipe 7 by clamping and magnetic attraction, etc. Not only can the storage capacity of dust be increased, but also the dust between the two filter screen plates 2 can be conveniently and quickly cleaned by opening the cover 8 during cleaning.

[0034] In some embodiments, one filter screen plate 2 is detachably connected to a spline sleeve 9, the spline sleeve 9 is provided with a spline shaft 11 that can slide up and down, and the spline shaft 11 is connected to a pull rod 12 at the bottom; further comprising a protective cover 13 connected to the bottom of the ventilation duct 1, the protective cover 13 has a limiting ring 14 at the bottom, the limiting ring 14 is provided with a special-shaped slot 15, the lower part of the pull rod 12 is connected to a special-shaped block 16, the special-shaped block 16 is slidably arranged in the special-shaped slot 15, and the thickness of the special-shaped block 16 is equal to or less than the thickness of the limiting ring 14.

[0035] If one of the filter screen plates 2 needs to be rotated to clean the dust covering the wind receiving surface, without positioning measures, it is easy to cause the filter screen plate 2 to rotate ceaselessly under the wind in daily use, thereby affecting the overall service life. In the above embodiment, the pull rod 12 is pulled downward, and then the pull rod 12 is rotated to drive the spline shaft 11, the spline sleeve 9 and the filter screen plate 2 to rotate. After rotating 180°, the position of the wind receiving surface and the leeward surface is exchanged. After adjusting the position of the filter screen, the special-shaped block 16 in the pull rod 12 is embedded in the special-shaped groove 15, thereby limiting the pull rod 12 from rotating again. The rotated filter screen plate 2 is cleaned by the beating part 6. In daily use, the dust on the wind receiving surface can also be blown off by the action of the wind.

[0036] Specifically, the top of the spline shaft 11 is connected with a magnetic attraction piece 17, and the spline shaft 11 is magnetically connected with the spline sleeve 9 through the magnetic attraction piece 17, so as to realize the positioning of the spline shaft 11 inside the spline sleeve 9, and to pull down a part from inside the spline sleeve 9 when rotation is needed. The spline sleeve 9 and the bottom of the ventilation duct 1 are jointly connected with a bearing 10, and the spline sleeve 9 rotates in the ventilation duct 1 through the bearing 10.

[0037] In some embodiments, a recess 18 is formed in the bottom of the pull rod 12, and a handle 19 is arranged in the recess 18, so as to facilitate pulling out the pull rod 12 through the handle 19.

[0038] In some embodiments, the beating part 6 is in a spherical structure and is made of rubber. This design has multiple functions and advantages. The spherical structure enables the beating part 6 to evenly disperse the force when contacting the filter screen plate 2, reduces the local pressure on the filter screen plate 2, thereby avoiding damage to the filter screen plate 2 caused by too high beating frequency. The rubber material has good elasticity and wear resistance, which can ensure the beating effect while reducing the wear of the filter screen plate 2 and prolonging the service life of the filter screen plate 2.

[0039] In some embodiments, one of the filter screen plates 2 that does not need to be rotated is connected with the ventilation duct 1 by a bolt, and the rotatable filter screen plate 2 is connected with the spline sleeve 9 by a bolt in a detachable manner. Through the above structure, it is convenient to install the two filter screen plates 2 during processing and manufacturing, and it is also convenient to disassemble, replace or repair when the filter screen plate 2 is damaged.

[0040] Although the specific embodiments of the application have been described in detail with reference to the accompanying drawings, the description is not a limitation on the scope of protection of the application. Various modifications or variations made by those skilled in the art on the basis of the technical solutions of the application without creative labor are still within the scope of protection of the application.
