Technical Field

[0001] The utility model provides a new grille structure, belongs to the technical field of air inlet and outlet protection equipment, and particularly relates to a new protective air-permeable grille structure. Background Art

[0002] Air inlets and outlets are very common in today's society. From large buildings to small electronic devices, they are all equipped with air vents. They are used for ventilation or heat dissipation. For example, the air outlet of the gas filter canister or the filter box of the filter element of a gas mask, the design of the air inlet and outlet can ensure the flow of ambient air inside and outside, and help to dissipate heat and cool the internal parts in time. At the same time, the air inlet and outlet also need to prevent dust, debris and other external substances from entering the external unit to protect the safety of the internal structure.

[0003] However, in applications similar to the above, there is not always enough space left for the installation of the grid structure of the air inlet and outlet. The vents in the basement and the exhaust vents on the roof need to consider the blocking factors of the surrounding building equipment. At the same time, the overall size of the equipment, such as gas masks, also needs to be considered. There are problems with insufficient space and inconvenience in use. At the same time, the existing air permeable grille structure is just a simple mesh filter that cannot prevent the intrusion of rainwater. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides a novel protective breathable grille structure, including an external plate 1, a plurality of blocking rings 2 of different sizes arranged in sequence and located on the external plate 1 and penetrating the external plate 1, a blocking surface 4 is placed above the inclined surface 3 of another adjacent blocking ring 2, a central connecting plate 6 is provided in the external plate 1 and is placed in the blocking ring 2, the blocking ring 2 is provided with an inclined surface 3 in the same direction, the upper end of the blocking ring 2 is provided with a blocking surface 4 facing opposite to the inclined surface 3, the blocking ring 2 is an arc-shaped inclined surface as a whole, and a water diversion groove 5 is formed between the blocking rings 2.

[0025] In this embodiment, an external plate 1 with a plurality of blocking rings 2 is provided, and the gaps formed by the blocking rings 2 are blocked by means of the blocking surface 4 on the external plate 1, thereby preventing direct particles from entering the interior of the device through the gaps in the blocking rings 2. At the same time, the inclined surface 3 on the blocking ring 2 allows rainwater to slide down along the surface of the blocking ring 2, and finally flow out of the external plate 1 after converging, thereby preventing rainwater from sliding into the interior of the device and causing damage to the internal structure.

[0026] like Figure 3 and Figure 4 As shown, a plurality of fixing rods 7 are connected below the connecting plate 6 and are evenly distributed with the connecting plate 6 as the center and correspond to the blocking ring 2. The fixing rods 7 have fixing grooves 8 that mesh with the blocking ring 2. A filter screen 9 fixedly connected to the external plate 1 is provided on the side of the fixing rods 7 that faces away from the external plate 1.

[0027] In this embodiment, the fixing rod 7 fixes the column blocking ring 2 with the help of the fixing groove 8 and connects them together to ensure stability; the filter screen 9 filters the debris again; it should be noted that the number of blocking rings 2 on the utility model is determined according to the specific usage, and the adaptability is high; at the same time, the device can be directly understood as opening a number of water diversion grooves 5 on the blocking plate 1, and the details can be referred to the attached figure of the specification Figure 5 and Figure 6 .

[0028] It should be emphasized that the utility model provides a breathable grid structure, which can be used for but not limited to gas filter canisters or gas masks. When the size and space are limited, the utility model optimizes the grid structure of the air inlet and arranges and designs the structure of the water guide groove with a reversely arranged folding grid structure, so as to maximize its protection performance against rainwater liquid splashing and dripping within the smallest size and space; adopts a reverse shielding structure with unlimited number of layers, and when the height is restricted, the cross-sectional area of ​​the air inlet can be increased by increasing the number of layers of the structure. The reverse shielding structure can effectively block unnecessary inlet and outlet air straight-through areas, and can block particles that impact the air inlet from the outside, while the reversely arranged guide groove can block the splashed liquid, rainwater, etc. and flow them to the outside in the form of a guide groove; the structural scheme of the air inlet and outlet method can effectively avoid damage to its interior caused by impacting particles and splashing liquid, thereby improving the protection performance and service life of the overall product.

[0029] When in use, install the external plate 1 to ensure that it is fixed in the required position; pass a number of blocking rings 2 of different sizes arranged in sequence through the corresponding holes on the external plate 1, so that they are perpendicular to the external plate 1 and penetrate its surface; place the connecting plate 6 in the blocking ring 2 to ensure that it is centered, and set the fixing rods 7 evenly distributed around the connecting plate 6 below the connecting plate 6; ensure that the fixing grooves 8 on the fixing rods 7 correspond to the blocking ring 2 so that they are meshed and fixed together; install the filter screen 9 on the side of the fixing rod 7 away from the external plate 1 to ensure that it is fixedly connected to the external plate 1; determine the required number of blocking rings according to the specific use situation to adapt to different environments and needs; when the water diversion groove 5 is provided on the external plate, ensure that it functions normally to guide rainwater to flow out of the grille structure smoothly and avoid entering the interior of the equipment; regularly check the status of the grille structure to ensure its normal operation, clean the filter screen, and prevent clogging by debris. By installing and using the utility model according to the above steps, it is possible to effectively prevent direct particles and rainwater from entering the interior of the equipment and protect the internal structure from damage.
