Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and more specifically, to a rainproof ventilation structure. Background Technology

[0002] Ventilation is an essential requirement for ensuring the quality of the internal environment and the normal operation of equipment in various buildings and industrial equipment.

[0003] Traditional ventilation openings typically employ a flat louver structure, which offers some ventilation but is significantly inadequate in terms of rain protection. During rainy weather, especially in strong winds and rain, rainwater can easily seep into the room or into equipment through the gaps in the louvers, potentially damaging indoor items, interfering with equipment operation, or even posing safety hazards. Furthermore, existing ventilation structures need improvement in terms of ventilation efficiency and airflow organization.

[0004] Therefore, it is necessary to design a new type of rainproof and ventilated structure that can effectively block rainwater from entering, ensure good ventilation, and have a certain degree of flexibility and adaptability.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the technical problems of poor rainproof performance, low ventilation efficiency, and lack of flexibility in existing ventilation structures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rainproof and ventilated structure, comprising:

[0008] Cabinet door outer frame;

[0009] A louver mounting bracket, which is fixedly connected to one side of the cabinet door outer frame;

[0010] A flow guide channel is provided at the inner bottom of the louver mounting bracket;

[0011] A waterproof lip, integrally formed around the four sides of the louver mounting bracket; and

[0012] The ventilation louver is installed inside the louver mounting bracket and located above the air guide groove. The ventilation louver is composed of multiple louver modules arranged in a double vertical direction. Each louver module includes vertical blades and horizontal blades that are fixed to each other and form a "7" shape.

[0013] In a preferred embodiment, the cabinet door frame is provided with multiple ventilation slots, and the multiple ventilation slots form a rectangular ventilation area.

[0014] In a preferred embodiment, the inner dimension of the waterproof lip is smaller than the outer dimension of the rectangular ventilation area, and the guide groove is located on one side of the bottom of the rectangular ventilation area.

[0015] In a preferred embodiment, the side of the louver mounting bracket is provided with a ventilation opening, and a filter screen is provided inside the ventilation opening.

[0016] In a preferred embodiment, a brushless fan is provided on the side of the louver mounting bracket and on the side of the vent.

[0017] In a preferred embodiment, the vertical blade and the horizontal blade are integrally formed, and at least two mounting posts are fixedly connected to the horizontal blade. The mounting posts are provided with mounting holes, and the mounting holes are connected to the louver mounting bracket by fasteners.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] This rainproof and ventilation structure utilizes a one-piece molding design with horizontal and vertical blades arranged in a figure-7 shape. Multiple louver modules are arranged in a double-vertical configuration. The gaps between the multiple louver modules meet the ventilation requirements while effectively preventing rainwater from passing through. This unique shape design is the key to achieving good rainproof and ventilation performance. By rationally designing the arrangement and angle of the louver modules, the ventilation volume and direction can be easily adjusted, improving ventilation efficiency and meeting diverse ventilation needs.

[0020] This rainproof ventilation structure, by placing the guide channel below the louvers, guides rainwater to flow outward along the outer frame of the cabinet door, thus providing good drainage. When rainwater impacts the ventilation louvers, the waterproof lip prevents rainwater from entering through the perimeter of the louvers, further blocking rainwater and achieving a better rainproof effect.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See also Figures 1-5 This utility model provides a rainproof and ventilated structure, including a cabinet door frame 1, a louver mounting bracket 3, a flow guide groove 31, and a ventilation louver 2.

[0030] In this embodiment, a plurality of ventilation slots 11 are provided on the outer frame 1 of the cabinet door, and the plurality of ventilation slots 11 form a rectangular ventilation area.

[0031] The ventilation slot 11 can be formed by drilling holes in the outer frame 1 of the cabinet door. The ventilation slot 11 can prevent foreign objects from entering the cabinet door through the outer frame 1 of the cabinet door.

[0032] In this embodiment: the louvered mounting bracket 3 is fixedly connected to one side of the cabinet door outer frame 1.

[0033] The louver mounting bracket 3 can be used to install and position the ventilation louvers 2.

[0034] In this embodiment: the side of the louver mounting bracket 3 is provided with a ventilation opening 5, and a filter screen 6 is provided inside the ventilation opening 5.

[0035] The filter screen 6 can be made of metal wire mesh, plastic mesh or fiber mesh. The filter screen 6 can be detached and connected to the vent 5 by existing fasteners such as bolts. This detachable filter screen 6 is convenient for regular cleaning and replacement. The filter screen 6 can effectively filter dust and impurities in the ventilated air, thus ensuring the cleanliness of the room or the inside of the equipment.

[0036] In this embodiment, a brushless fan 4 is provided on the side of the louver mounting bracket 3 and on the side of the ventilation opening 5.

[0037] The brushless fan 4 operates with low noise and can accelerate ventilation.

[0038] In this embodiment: the ventilation louver 2 is installed in the louver mounting bracket 3. The ventilation louver 2 is composed of multiple louver modules 21 arranged in double vertical directions. The louver module 21 includes vertical blades 211 and horizontal blades 212 that are fixed to each other. The vertical blades 211 and horizontal blades 212 are integrally formed and form a "7" shape.

[0039] The louver module 21 is made of metal materials, such as aluminum alloy and stainless steel, which ensures strength and durability. The louver module 21 can be processed by die stamping or extrusion molding to form a "7" shape with vertical blades 211 and horizontal blades 212. By using the "7" shaped louver module 21 and arranging multiple louver modules 21 in a double longitudinal arrangement, an effective ventilation gap can be reserved. This ventilation gap can not only ensure ventilation needs, but also facilitate the drainage of rainwater. This effectively prevents rainwater from entering the cabinet door frame 1, ensuring that the interior or equipment is not affected by rainwater even in heavy wind and rain.

[0040] In this embodiment, at least two mounting posts are fixedly connected to the horizontal blade 212. The mounting posts are provided with mounting holes 213, and the mounting holes 213 are connected to the louver mounting bracket 3 by fasteners.

[0041] The mounting column is integrally formed with the louver module 21. Fasteners such as bolts and elastic clips can be used as mounting components for the louver module 21. This ensures the louver module 21 is installed stably while facilitating maintenance and disassembly. Since the louver module 21 can be quickly disassembled and adjusted using fasteners, the arrangement and angle of the louver module 21 can be rationally designed to adjust the ventilation volume and direction according to different environmental conditions and actual needs, thereby meeting diverse ventilation requirements and improving the flexibility and adaptability of the louver module 21. In addition, during installation, the angle of the louver module 21 must be consistent to ensure ventilation effect and overall aesthetics.

[0042] In this embodiment: the guide channel 31 is set at the inner bottom of the louver mounting bracket 3, and the guide channel 31 is located below the ventilation louver 2 and above the guide channel 31. The guide channel 31 is set on one side of the bottom of the rectangular ventilation area.

[0043] The cross-sectional shape of the guide channel 31 can be V-shaped, U-shaped or trapezoidal, preferably V-shaped with an angle greater than 90 degrees. Since the guide channel 31 is set along the length direction of the horizontal blade 212, the water-blocking surface formed by the combination of the vertical blade 211 and the horizontal blade 212 can guide the rainwater flowing downstream through the guide channel 31 until it is discharged outward at the ventilation slot 11.

[0044] In this embodiment, the waterproof lip 32 is integrally set around the four sides of the louver mounting bracket 3, and the inner dimension of the waterproof lip 32 is smaller than the outer dimension of the rectangular ventilation area.

[0045] During the process of intercepting rainwater by the ventilation louvers 2, the setting of the waterproof lip 32 being smaller than the rectangular ventilation area can easily block the perimeter of the ventilation louvers 2. This can prevent the impacting rainwater from entering the ventilation opening 5 through the perimeter of the louver module 21, so that the rainwater can flow down along the waterproof lip 32, thus achieving a better rainproof effect. Therefore, combined with the above technical solutions, it can be seen that the rainproof ventilation structure of this application can effectively block rainwater from entering, ensure good ventilation effect, and has a certain degree of flexibility and adaptability, making it quite practical.
