[0002] The fresh air system refers to introducing fresh air into the room through the fresh air equipment to improve the indoor air quality. In the fresh air system, the air outlet structure refers to the part that discharges indoor air to the outside. The fresh air equipment has a wide range of application scenarios, and it is necessary to install a fresh air machine for indoor and outdoor ventilation whether in the south or the north.

[0003] The air outlet structure usually includes an air outlet on the indoor wall or ceiling, through which indoor air is discharged, and a pipeline connecting the air outlet and the fresh air equipment to ensure smooth air flow. An exhaust fan is also installed in the pipeline to discharge indoor air to the outside through the air duct.

[0004] The conventional exhaust fan is provided with a filtering mechanism to filter impurities and dust from the outside. However, long-term use can cause too much dust or impurities to accumulate, which can easily form a flocculent shape and cause blockage, thereby affecting the air outlet speed. Therefore, the filtering mechanism needs to be frequently disassembled and cleaned. Most filtering mechanisms are installed in hidden places, which is not convenient to disassemble. Therefore, it is necessary to provide a fresh air outlet structure to solve the above problems.

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0030] As shown in Figure 1 The present application provides a new air outlet structure, which comprises an air outlet pipe 1, one end of the air outlet pipe 1 is installed on a new air equipment, the other end is installed on a wind port on a wall, and a exhaust fan (not shown in the figure) is also fixedly installed inside the air outlet pipe 1, which is a prior art for discharging indoor air outside through the air outlet pipe 1.

[0031] One end of the air outlet pipe 1 near the wind port is fixedly installed with a filter screen 11, which can first filter the larger dust and impurities from the outside, prolong the service life of the exhaust fan, and the filter screen 11 can be disassembled, and a sealing ring 12 is fixedly installed outside the air outlet pipe 1 port, which can improve the connection sealing performance of the air outlet pipe 1 and the wall wind port;

[0032] As shown in Figure 1 and Figure 3 In order to remove the dust attached to the outer surface of the filter screen 11, a scraper 2 is rotatably connected at the center of the filter screen 11, the length of the scraper 2 is greater than the radius of the filter screen 11, and a movable slot 21 is formed on the sealing ring 12, the movable slot 21 penetrates the sealing ring 12, and the movable slot 21 is circularly arranged with the center of the filter screen 11;

[0033] The end of the scraper 2 away from the center of the circle is fixedly provided with a connecting rod 22, which is located in the movable slot 21, so that the connecting rod 22 is slid along the movable slot 21, the scraper 2 is driven to rotate along the center of the filter screen 11, and thus the dust on the surface of the scraper 2 is scraped off.

[0034] In order to prevent the scraper 2 from shaking, a clamping block 24 is hingedly connected to one end of the connecting rod 22, and a clamping groove 23 is formed in the side of the sealing ring 12 away from the scraper 2, and the clamping block 24 and the clamping groove 23 are matched with each other, so that when the scraper 2 is not used, the clamping block 24 is clamped in the clamping groove 23, and thus the scraper 2 is fixed.

[0035] In the present application, a handle 25 is fixedly provided on one side of the clamping block 24, and the clamping block 24 can be conveniently taken out through the handle 25.

[0036] In order to prevent dust from entering the room through the movable slot 21, a blocking ring 26 is rotatably connected in the movable slot 21, and the blocking ring 26 is fixedly provided on the connecting rod 22, so that when the connecting rod 22 rotates, the blocking ring 26 is also driven to rotate, thereby ensuring the sealing performance of the sealing ring 12 and ensuring the normal rotation of the scraper 2 and the connecting rod 22.

[0037] In order to prevent the dust scraped off by the scraper 2 from falling, a collecting box 3 is provided on one side of the filter screen 11, as shown in the drawings. Figures 1-2 The end of the collecting box 3 facing the filter screen 11 is provided in a circular arc shape and corresponds to the sealing ring 12, and an extension plate 31 is fixedly provided on the upper end of the collecting box 3, and a mounting hole 32 is formed in the extension plate 31, and a hole (not shown in the drawings) is formed in the sealing ring 12, the hole and the mounting hole 32 correspond to each other, a bolt 33 is arranged in the mounting hole 32, the bolt 33 has a nut (not shown in the drawings) engaged therewith, and thus the bolt 33 is fixed in the hole and the mounting hole 32 through the nut during installation, thereby fixing the collecting box 3 on the sealing ring 12.

[0038] As described above, when the filter screen 11 needs to be cleaned, the clamping block 24 is manually pulled out and rotated through the handle 25, so that the connecting rod 22 and the scraper 2 are driven to rotate, and thus the impurities on the filter screen 11 are scraped off by the scraper 2 and fall into the collecting box 3, thereby completing the cleaning of the surface of the filter screen 11. When the air outlet pipe 1 needs to be removed and cleaned after a period of use, the impurities in the collecting box 3 can be removed, and the filter screen 11 can be cleaned together, thereby reducing the probability of the exhaust fan being blocked by dust or impurities, and improving the speed of the air outlet without frequent disassembly and cleaning.

[0039] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
