Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, and more specifically to a rust-proof air outlet metal pipe. Background Art

[0002] The fresh air system is a device used to replace indoor and outdoor air, which can ensure indoor ventilation.

[0003] The fresh air system consists of air supply and exhaust. When air is supplied to the room, part of the air in the room will be squeezed out to the outside through the pipe to ensure normal indoor air pressure.

[0004] The exhaust duct leads directly to the outside world. In order to prevent birds and mice from entering the duct, a barrier net is installed in the duct. However, impurities brought by birds and mice, as well as branches and leaves that enter with the wind will still cause blockage in the barrier net, so the barrier net needs to be cleaned frequently.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a rust-proof air outlet metal pipe.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] The rust-proof air outlet metal pipe comprises a pipe body, wherein a bracket is rotatably connected inside the pipe body, a filter is installed on one side of the bracket, a fan blade is installed on the other side of the bracket, a cleaning component is installed on the filter, and the cleaning component is in contact with the inner wall of the pipe body.

[0009] The utility model is further configured as follows: the cleaning assembly comprises a plurality of connecting rods, and the connecting rods are arranged at the edge of the filter screen at annular intervals.

[0010] The utility model is further configured as follows: a plurality of protrusions are formed on the inner wall of the connecting rod away from the tube body, the plurality of protrusions are arranged at equal intervals along the length direction of the connecting rod, and the positions of two protrusions respectively located on two adjacent connecting rods are staggered.

[0011] The utility model is further configured as follows: the filter screen is arranged in an inclined shape in the tube body.

[0012] The utility model is further configured as follows: a rain cover is arranged at the opening of the tube body close to one end of the filter screen.

[0013] The utility model is further configured as follows: the tube body and the rain cover are both made of stainless steel metal material.

[0014] In summary, the utility model has the following beneficial effects:

[0015] When the metal pipe is discharging air, the wind will flow through the fan blades, bracket and filter to the outside of the pipe body. The fan blades can be used to drive the fan blades, bracket and filter to rotate. The inclined filter can be rotated to make impurities attached to the filter fall off easily. Light impurities will flow out of the pipe body with the wind, and heavy impurities will fall to the bottom of the inner wall of the pipe body. The impurities will come into contact with protrusions at different positions, so that the impurities can be pushed out of the pipe body by the protrusions. This can reduce the probability of the pipe body being blocked and reduce the frequency of cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0021] like Figure 1As shown, the present application provides a rust-proof air outlet metal pipe, including a pipe body 1. When in use, the two ends of the pipe body 1 will face the outdoors and the fan respectively. A filter screen 2 is arranged inside the pipe body 1, and the filter screen 2 will block the pipe body 1, so that impurities such as mice, birds, branches and leaves cannot enter the fan through the pipe body 1, thereby ensuring the protection of the fan. A rain cover 3 is arranged at the opening of the pipe body 1 near one end of the filter screen 2. The rain cover 3 blocks the side of the pipe body 1 facing the sky, thereby reducing the probability of rainwater directly entering the pipe body 1. The pipe body 1 and the rain cover 3 are both made of stainless steel metal material, which is corrosion-resistant and not easy to rust, thereby increasing the service life.

[0022] like Figure 2 and Figure 3 As shown, a bracket 4 is rotatably connected in the tube body 1, one side of the bracket 4 is fixedly connected to the filter 2, and a fan blade 5 is installed on the other side of the bracket 4. When the fan causes the metal tube to discharge air, the wind will flow through the fan blade 5, the bracket 4 and the filter 2 to the outside of the tube body 1. The fan blade 5 is used to drive the fan blade 5, the bracket 4 and the filter 2 to rotate, and the filter 2 will drive the impurities attached to the surface of the filter 2 to rotate together. Combined with the flowing wind, the probability of impurities falling off from the filter 2 can be increased. The filter 2 is arranged in an inclined shape in the tube body 1, so that the filter port of the filter 2 is also inclined. The rotation of the filter 2 can continuously change the direction of the filter port, thereby increasing the probability of impurities falling off from the filter port. Light impurities flow out of the tube body 1 with the wind, thereby realizing automatic cleaning of the tube body 1, while heavy impurities will fall to the bottom of the inner wall of the tube body 1, thereby reducing the probability of blocking the entire filter 2.

[0023] like Figure 2 and Figure 3 As shown, the filter screen 2 is installed with a cleaning assembly, which includes a plurality of connecting rods 6, which are arranged at annular intervals at the edge of the filter screen 2, and the connecting rods 6 are in contact with the inner wall of the tube body 1. When the filter screen 2 rotates, the connecting rods 6 will scrape the inner wall of the tube body 1 to reduce the probability of impurities adhering to the inner wall of the tube body 1, wherein the connecting rod 6 is formed with a plurality of protrusions 7 away from the inner wall of the tube body 1, and the plurality of protrusions 7 are arranged at equal intervals along the length direction of the connecting rod 6, and the positions of two protrusions 7 located on two adjacent connecting rods 6 are staggered.

[0024] Heavy impurities will remain at the bottom of the inner wall of the tube body 1. The position of the connecting rod 6 changes continuously due to the rotation, so that the heavy impurities will contact the protrusions 7 at different positions on different connecting rods 6. Due to the position of the protrusion 7, the effect of the spiral rod can be simulated, so that the larger impurities can be pushed out of the tube body 1 by the protrusion 7.

[0025] In summary, the air outlet metal pipe provided in this embodiment can reduce the probability of the pipe body 1 being blocked and reduce the frequency of cleaning and maintenance.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
