Detailed Implementation

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-6 As shown, this utility model embodiment proposes a built-in rainproof structure, including a cabinet 1 and an insect-proof net assembly 2. The insect-proof net assembly 2 includes a support plate 21, two side plates 22, a top plate 23, and a sloping slide plate 24, wherein: The back panel 11 of the cabinet 1 is provided with multiple air inlet louvers 111 and drain holes 112, with the drain holes 112 located below the air inlet louvers 111. The bracket plate 21 is parallel to the back plate 11 and located inside the cabinet 1. The bracket plate 21 covers the area of ​​the multiple air inlet louvers 111. The bracket plate 21 is provided with through slots 211 for ventilation. The two side plates 22 are respectively connected to both sides of the support plate 21 and are both connected to the back plate 11; The top plate 23 is connected to the top of the support plate 21 and the back plate 11; The inclined slide 24 is connected to the bottom of the support plate 21 and the back plate 11. The end of the inclined slide 24 connected to the back plate 11 is lower than the end connected to the support plate 21, and the bottom of the inclined slide 24 is not higher than the bottom of the drain hole 112.

[0020] The built-in rainproof structure proposed in this embodiment effectively blocks rainwater from entering on rainy days through the air inlet louvers 111. A small amount of rainwater will adhere to the support plate 21 and flow slowly downwards, flowing through the inclined slide plate 24 to the drain outlet for discharge. This can greatly reduce the amount of rainwater entering the cabinet 1. Moreover, the support plate 21 is located inside the cabinet 1. This built-in design does not occupy the external space of the cabinet 1, which can make the overall space occupied by the cabinet 1 smaller and facilitate flexible layout in small spaces.

[0021] In some embodiments, the insect-proof net assembly 2 further includes an insect-proof net 25. A through-hole 211 is provided on the support plate 21, and the insect-proof net 25 is installed on the support plate 21 and corresponding to the through-hole 211. The insect-proof net 25 can prevent insects, poplar catkins, and willow catkins from entering the cabinet 1. Furthermore, a small amount of rainwater entering through the air inlet louvers 111 will adhere to the insect-proof net 25, further reducing rainwater entering the cabinet 1 and improving the device's rainproof capability.

[0022] In some embodiments, such as Figure 3 and 4 As shown, multiple air inlet louvers 111 are evenly distributed and fixed on the back panel 11 in a vertical direction and located inside the back panel 11. Each air inlet louver 111 has an air inlet 1111 at its top, and the air intake direction of the air inlet louvers 111 is from bottom to top. The evenly distributed design of the air inlet louvers 111 makes the air intake position more uniform, ensuring more even airflow into the cabinet 1 and preventing turbulence. Furthermore, the air inlet 1111 is located at the top of the air inlet louvers 111, ensuring the air intake direction is from bottom to top, thus minimizing the possibility of rainwater automatically entering the air inlet louvers 111. The air inlet louvers 111 can be formed by stamping on the back panel 11. Located inside the back panel 11, the air inlet louvers 111 do not occupy space outside the cabinet 1. Compared to existing technologies that install louver assemblies outside the cabinet 1, this reduces the number of components and the space occupied inside the cabinet 1, and eliminates the need for a separate rainproof structure for the louver assembly.

[0023] In other embodiments, the air inlet louver 111 can be located on the outside of the back panel 11, with the air intake direction of the air inlet louver 111 being from bottom to top, and the air inlet 1111 being located at the bottom of the air inlet louver 111. The air inlet 1111 being located at the top of the air inlet louver 111 ensures that the air intake direction of the air inlet louver 111 is from bottom to top, minimizing the possibility of rainwater automatically entering the air inlet louver 111. The air inlet louver 111 can be formed by stamping on the back panel 11, reducing the number of parts and eliminating the need for a separate rainproof structure for the louver assembly.

[0024] In some embodiments, the back panel 11 is provided with air guide holes 113 corresponding to the air inlet louvers 111, and the air inlet louvers 111 are provided with guide surfaces 1112, which connect the air inlet 1111 and the air guide holes 113. By connecting the air inlet 1111 and the air guide holes 113 at both ends of the guide surface 1112, the airflow can be guided, resulting in better air intake of the air inlet louvers 111 and facilitating heat dissipation of the cabinet 1.

[0025] In some embodiments, the bottom of the inclined slide 24 is flush with the bottom of the drain hole 112. This arrangement prevents rainwater from accumulating between the bottom of the inclined slide 24 and the back plate 11, allowing it to drain promptly from the drain hole 112 and improving the reliability of the device.

[0026] In some embodiments, the angle between the inclined slide 24 and the back plate 11 is 20 to 60 degrees. At this angle, the rainwater flows down faster, and more air inlet louvers 111 can be arranged at the same height to improve air intake efficiency. In addition, it can also be used as a dust removal port for dust removal when the dust filter is used for dust removal.

[0027] In some embodiments, the air inlet louvers 111 are provided in two sets, and the drain holes 112 and the insect-proof net assembly 2 are each provided in two sets, with each set of air inlet louvers 111 corresponding to one drain hole 112 and one insect-proof net assembly 2. The back panel 11 is separated by other structures (such as a lifting mechanism), so the two types of air inlet louvers 111 are respectively located on both sides of the vertical center line of the back panel 11, with each set of air inlet louvers 111 corresponding to one drain hole 112 and one insect-proof net assembly 2. Of course, the insect-proof net assembly 2 is a modular structure, and the number can be designed according to actual needs.

[0028] In some embodiments, the built-in rainproof structure is used in devices such as air conditioners, fresh air units, communication equipment, and power equipment that are equipped with cabinets 1, and has a wide range of applications and good versatility.

[0029] The working principle of the built-in rainproof structure in this embodiment of the utility model is as follows: the air inlet louvers 111 effectively block the inflow of rainwater on rainy days. A small amount of rainwater entering through the air inlet louvers 111 will adhere to the insect screen 25. The rainwater flows slowly downward and flows through the inclined slide 24 to the drain outlet for discharge. This can greatly reduce the amount of rainwater entering the cabinet 1. Moreover, the support plate 21 is located inside the cabinet 1. This built-in design does not occupy the external space of the cabinet 1, which can make the overall space occupied by the cabinet 1 smaller and facilitate flexible layout in small spaces.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
