[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See Figure 1 and Figure 2 The present invention provides an air guide cover comprising a main body 1 and side portions 2. The main body 1 has a central through-hole 11 extending therethrough for installation of a heat dissipation device such as a fan. The side portions 2 are protruding from the peripheral edge of the main body 1. The side portions 2, located at the bottom of the main body 1, are tilted up and down along their extension direction, so that their two ends are at different heights.

[0030] In this way, the side portion 2 at the bottom of the main body 1 is tilted up and down along its extension direction, so that when foreign objects such as leaves and dust fall on the side portion 2 at the bottom of the main body 1, they can use their own gravity to slide to the lower end, so that the foreign objects accumulate in the lower corner, which is convenient for cleaning. This not only greatly reduces the labor intensity, but also avoids the fan and other components of the heat dissipation unit from blowing foreign objects to various angles of the air guide cover when they are in operation, thereby not affecting the normal operation of the heat dissipation unit, and is conducive to improving the service life of the heat dissipation unit.

[0031] The side portion 2 protrudes from one side of the main body 1, directing the cold airflow generated by the operation of cooling components such as the fan and preventing it from spreading outward, thereby improving the airflow guidance effect. Furthermore, the end of the side portion 2, away from the main body 1, extends outward at an angle relative to the main body 1, forming a prism-like structure for the air guide, which further facilitates the dispersion and disturbance of the cold airflow, thereby further improving the airflow guidance effect.

[0032] Specifically, the side portion 2 includes an upper side portion 21, a left side portion 22, a right side portion 23 and a bottom side portion 24 protruding toward the same side of the main body portion 1. The upper side portion 21, the left side portion 22, the bottom side portion 24 and the right side portion 23 are connected in sequence to close around the circumference of the main body portion 1, and the bottom side portion 24 is tilted up and down along its extension direction so that the two end portions in the extension direction are at different height positions.

[0033] The main body 1 of the present invention is a square plate-like structure, with side portions 2 distributed around the main body 1 to guide air. The bottom side portion 24 is tilted to facilitate the accumulation of foreign matter such as leaves and dust in the lower corner due to their own weight, making it easier to clean and reducing labor intensity.

[0034] Among them, the inclination angle of the side portion 2 located at the bottom of the main body 1 is 15-20°, that is, the inclination angle of the bottom side portion 24 is 15-20°. This angle range can ensure that foreign objects can slide to the lower end by their own gravity, and avoid the inclination angle being too large to increase the volume and occupied space of the air guide cover, thereby improving space utilization.

[0035] The first end 241 of the bottom portion 24 is connected to the left side portion 22, and the second end 242 of the bottom portion 24 is connected to the right side portion 23. The first end 241 and the second end 242 are at different heights, with the first end 241 being located diagonally above the second end 242. This allows foreign matter such as leaves and dust to fall onto the bottom portion 24 and slide down to the second end 242 under its own weight, making it easier to clean.

[0036] See Figure 2 and Figure 3The second end 242 is provided with an opening 243 that vertically extends through the second end 242. When foreign matter such as leaves and dust falls onto the bottom side portion 24, it slides down to the second end 242 by its own weight and then falls out of the air guide cover through the opening 243 of the second end 242, thereby discharging the foreign matter without the need for manual cleaning.

[0037] On this basis, a cover plate 3 is provided at the second end 242, covering the opening 243 and detachably connected to the second end 242. The provision of the cover plate 3 allows for the time-based cleaning of foreign matter such as leaves and dust. When cleaning is necessary, the cover plate 3 can be opened to open the opening 243. Once cleaning is complete, the cover plate 3 can be closed. This prevents foreign matter from falling through the opening 243 while the device is operating, thereby preventing it from affecting the normal operation of other devices.

[0038] A slot 244 is defined at the second end 242, corresponding to the cover plate 3. The cover plate 3 is mounted on the second end 242 and can slide back and forth along the slot 244. The cover plate 3 and the slot 244 are penetrated by a screw 4 and are positioned by a nut 5. The direction in which the slot 244 is set corresponds to the sliding direction of the cover plate 3. In this utility model, the slot 244 extends in a left-right direction. When there is no need to clean foreign matter such as leaves or dust, the cover plate 3 closes the opening 243. The screw 4 sequentially penetrates the slot 244 and the cover plate 3, and the nut 5 is then tightened to securely seal the opening 243. When it is necessary to clean foreign matter such as leaves or dust, the nut 5 is loosened, allowing the cover plate 3 to slide along the slot 244 to open the opening 243, allowing foreign matter such as leaves or dust to fall through the opening 243.

[0039] A gasket 7 may be provided between the screw rod 4 and the second end 242 having the sliding groove 244 to increase the contact area and thus improve the stability of the connection.

[0040] It should be noted that the cover plate 3 is preferably arranged on the outside of the bottom of the second end 242, and the nut 5 is screwed from the outside of the bottom of the cover plate 3 to move closer to or away from the cover plate 3. In this way, it is convenient to operate the cover plate 3 to slide, so as to efficiently clean foreign objects such as leaves and dust, and the labor intensity is low.

[0041] In addition, an air ring 6 is protruding from the peripheral edge of the through hole 11, and the air ring 6 protrudes away from the side portion 2. The arrangement of the air ring 6 is conducive to improving the convenience of connecting the air guide cover with other components.

[0042] Based on the above-mentioned air guide, the present invention further provides a ventilation device having the above-mentioned air guide, thereby facilitating the removal of foreign matter accumulated in the ventilation device. The ventilation device can be applied to fields such as engineering machinery, such as excavators, loaders, bulldozers, and more specifically, air conditioners, fans, exhaust fans, and other devices. The air guide can be used to efficiently and quickly remove foreign matter, thereby improving the ventilation effect and service life of the equipment and reducing the labor intensity of the operator.

[0043] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
