[0037] As shown in Figure 1 In a first aspect, embodiments of the present disclosure provide a cabinet, which includes a cabinet plate body 1 and a cover body 2; the cabinet plate body 1 and the cover body 2 are connected and enclosed to form an air duct cavity 3; the air duct cavity 3 is provided with a first ventilation structure 31 and a second ventilation structure 32, the first ventilation structure 31 is arranged at one of the cabinet plate body 1 and the cover body 2 close to the outside of the cabinet, and the second ventilation structure 32 is arranged at one of the cabinet plate body 1 and the cover body 2 close to the inside of the cabinet; in the up-down direction, the bottom end position of the second ventilation structure 32 is higher than that of the first ventilation structure 31.

[0038] It should be understood that the cabinet includes a cabinet body and a cabinet door connected to the cabinet body. The cabinet plate body 1 can be part of the cabinet door or part of the cabinet body. In some scenarios, the cabinet body and the cabinet door respectively correspond to the above-mentioned cabinet plate body 1, which is not a limitation.

[0039] It should be understood that the structure of the cabinet plate body 1 and the cover body 2 is not a limitation, and they can only form the air duct cavity 3, which will be exemplarily described later in the specification.

[0040] In the present embodiment, the cabinet plate body 1 and the cover body 2 are connected and enclosed to form the air duct cavity 3, the first ventilation structure 31 provided by the air duct cavity 3 is arranged at one of the cabinet plate body 1 and the cover body 2 close to the outside of the cabinet, and the second ventilation structure 32 provided by the air duct cavity 3 is arranged at one of the cabinet plate body 1 and the cover body 2 close to the inside of the cabinet, so that the air outside the cabinet can enter the air duct cavity 3 through the first ventilation structure 31, and then flow out of the air duct cavity 3 through the second ventilation structure 32 to enter the inside of the cabinet, meeting the air circulation demand between the inside and the outside of the cabinet. In this process, since the bottom end position of the first ventilation structure 31 is arranged to be lower than that of the second ventilation structure 32, even if the cabinet is used in an outdoor environment, the possibility of rainwater flowing into the cabinet through the second ventilation structure 32 after flowing into the air duct cavity 3 through the first ventilation structure 31 can be reduced, the waterproof performance of the cabinet can be improved on the basis of considering the ventilation and heat dissipation performance of the cabinet, and the service life and safety of the electronic equipment with the cabinet can be improved.

[0041] Optionally, the cabinet plate body 1 and the cover body 2 are detachably connected. For example, the two can be connected in a fastener connection, a clamping connection, etc., which is not as a limitation.

[0042] In this way, the cabinet plate body 1 and the cover body 2 are detachably connected, so that the inside of the air duct cavity 3 can be maintained by detaching the cover body 2 and the cabinet plate body 1, and the structure is simple and practical.

[0043] Optionally, from the first ventilation structure 31 to the second ventilation structure 32 in the air duct cavity 3, the position of the point in the air duct cavity 3 in the up-down direction gradually rises.

[0044] In this way, even if the cabinet is used in an outdoor environment, rainwater enters the air duct cavity 3 through the first ventilation structure 31, and due to the fact that from the first ventilation structure 31 to the second ventilation structure 32 in the air duct cavity 3, the position of the point in the air duct cavity 3 in the up-down direction gradually rises, under the action of gravity, the rainwater entering the air duct cavity 3 is less likely to flow to the second ventilation structure 32, and more likely to flow out of the air duct cavity 3 through the first ventilation structure 31, ensuring the waterproof performance of the cabinet.

[0045] Optionally, the top end position of the first ventilation structure 31 is lower than the bottom end position of the second ventilation structure 32.

[0046] Those skilled in the art should understand that in this specification, the top end of the first ventilation structure 31 refers to the top end of the part that can be used for ventilation, and the bottom end of the first ventilation structure 31 refers to the bottom end of the part that can be used for ventilation. For example, when the first ventilation structure 31 only includes the first ventilation hole 311 described later, the top end of the first ventilation structure 31 can be understood as the upper edge of the first ventilation hole 311, and the bottom end of the first ventilation hole 311 can be understood as the lower edge of the first ventilation hole 311.

[0047] In this way, the possibility of rainwater entering the air duct cavity 3 through the upper part of the first ventilation structure 31 can be further reduced, and the waterproof performance of the cabinet can be improved.

[0048] As shown in Figure 1 Optionally, the cabinet plate body 1 and the cover body 2 are sequentially distributed in the horizontal direction; wherein the cover body 2 is located on the side of the cabinet plate body 1 close to the inside of the cabinet, the first ventilation structure 31 is arranged on the cabinet plate body 1, and the second ventilation structure 32 is arranged on the cover body 2.

[0049] Specifically, the cabinet plate body 1 and the cover body 2 are arranged vertically, but it should be understood that they are not limited thereto, and the cabinet plate body 1 and the cover body 2 can also be arranged obliquely, which can be arranged according to actual needs.

[0050] As shown in Figure 1As shown, the first ventilation structure 31 includes a first ventilation hole 311, and the second ventilation structure 32 includes a second ventilation hole. The first ventilation hole 311 is formed on the cabinet plate body 1, and the second ventilation hole is formed on the cover body 2. The position of the second ventilation hole in the up-down direction is higher than the position of the first ventilation hole 311 in the up-down direction.

[0051] In this way, the cabinet plate body 1 and the cover body 2 are reasonably arranged, the positions of the first ventilation structure 31 and the second ventilation structure 32 are arranged conveniently, the structure is simple, and the practicality is strong.

[0052] As shown in the figure, Figure 1 Optionally, the cover body 2 is formed with a groove 21. The cover body 2 is attached to the cabinet plate body 1 at the edge of the groove 21, so that the cover body 2 and the cabinet plate body 1 form the air duct cavity 3.

[0053] As shown in the figure, Figure 1 The edge of the groove 21 is towards the cabinet plate body 1, that is, towards the right in the figure. The first ventilation hole 311 is formed on the cabinet plate body 1, and the second ventilation hole is formed on the cover body 2 at a position higher than the first ventilation hole 311.

[0054] In this way, when the cover body 2 is attached to the cabinet plate body 1 at the edge of the groove 21, the cover body 2 and the cabinet plate body 1 form the air duct cavity 3. In this case, the structure complexity of the cabinet plate body 1 can be reduced. For example, the cabinet plate body 1 can have a flat plate structure 11, and the flat plate structure 11 and the cover body 2 form the air duct cavity 3. The structure is simple, and the practicality is strong. The structure can be applied to new production cabinets and old cabinet modification.

[0055] As shown in the figure, Figure 1 Further, the groove 21 includes a groove bottom wall 201, a first groove side wall 202, a second groove side wall 203, and a third groove side wall 204. The groove bottom wall 201 is opposite to the groove opening 205. The first groove side wall 202 is the top groove side wall of the groove 21. The second groove side wall 203 is the bottom groove side wall of the groove 21. The third groove side wall 204 is the groove side wall adjacent to the groove bottom wall 201 and the first groove side wall 202.

[0056] Specifically, the groove bottom wall 201 and the groove opening 205 are opposite to each other along the Y-axis direction. The groove bottom wall 201 is on the left. The first groove side wall 202 and the second groove side wall 203 are opposite to each other along the Z-axis direction. The first groove side wall 202 is on the top.

[0057] As shown in the figure, Figure 1 The figure shows that the second ventilation structure 32 is arranged on the groove bottom wall 201.

[0058] However, it should be understood that, without violating the technical concept of this disclosure, one or more of the bottom wall 201, the first side wall 202, and the third side wall 204 of the tank may be respectively provided with a second ventilation structure 32.

[0059] It should be understood that when only the bottom wall 201 of the groove is provided with the second ventilation structure 32, the depth of the groove 21 in the Y-axis direction can be set to be relatively small, which is beneficial to reduce the space occupied by the air duct cavity 3 when the air duct cavity 3 is formed.

[0060] like Figure 1 As shown, optionally, the cabinet also includes a ventilation and dustproof structure 5; the first ventilation structure 31 includes a first ventilation hole 311, and the ventilation and dustproof structure 5 is disposed at the first ventilation hole 311.

[0061] The ventilation and dustproof structure 5 is a structure that can maintain ventilation while also providing a certain degree of dust protection. The ventilation and dustproof structure 5 can adopt relevant technologies or the technologies described later in this specification, which are not intended to be limiting.

[0062] Thus, the ventilation and dustproof structure 5 can protect the internal space of the cabinet to a certain extent. It has a simple structure and is highly practical.

[0063] Optionally, in the above embodiments, the cabinet panel 1 and the cover 2 are sealed together.

[0064] Specifically, the cabinet includes a first sealing gasket 4, which is disposed at the joint between the cabinet panel 1 and the cover 2 to ensure the sealing performance at the joint.

[0065] Optionally, the air duct cavity 3 is also provided with a first drainage structure 7, which is connected to the bottom end of the air duct cavity 3, and the position of the first drainage structure 7 in the vertical direction is lower than the bottom end of the first ventilation hole 311.

[0066] like Figures 1 to 4 As shown, when the cover 2 is located on the side of the cabinet 1 near the inside of the cabinet, the first drainage structure 7 includes a drainage hole provided on the cabinet 1, the inner end of the drainage hole is connected to the air duct cavity 3, and the outer end of the drainage hole is connected to the external environment.

[0067] Thus, for reference Figure 6 As shown, when rainwater enters the air duct cavity 3 through the first ventilation structure 31, the water accumulated in the air duct cavity 3 will be discharged through the first drainage structure 7, ensuring the ventilation performance of the air duct cavity 3.

[0068] like Figure 3 and Figure 4As shown, the ventilation dustproof structure 5 has a rim portion 51 outside the first ventilation hole 311, the projection of the rim portion 51 on a setting plane covers the projection of the first drainage structure 7 on the setting plane, and the rim portion 51 is provided with a clearance gap 52 at a position corresponding to the first drainage structure 7, wherein the setting plane is a plane on which the outer edge of the first ventilation hole 311 is located.

[0069] It should be understood that the setting plane is perpendicular to the Y-axis direction. The projection of the rim portion 51 on the setting plane covers the projection of the first drainage structure 7 on the setting plane, and at the same time, the rim portion 51 is provided with a clearance gap 52 at a position corresponding to the first drainage structure 7. The rim portion 51 can be used to form a cover for the first drainage structure 7, and the drainage space requirement of the first drainage structure 7 can be met through the clearance gap 52.

[0070] Optionally, the ventilation dustproof structure 5 includes a louver 5A.

[0071] For example, the louver 5A extends into the first ventilation hole 311 and abuts against the edge of the first ventilation hole 311 through the rim portion 51 thereof (see Figure 3 and Figure 4 As shown). The louver 5A can achieve certain ventilation and dustproof effects.

[0072] In an optional scheme of the louver 5A, the louver 5A includes a mounting frame 53 and a grid 54, the mounting frame 53 is mounted at the first ventilation hole 311, and the grid 54 is detachably connected with the mounting frame 53.

[0073] For example, the louver 5A includes a mounting frame 53 and a grid 54, the mounting frame 53 is at least partially arranged in the first ventilation hole 311, and the grid 54 is detachably connected with the mounting frame 53.

[0074] The grid 54 and the mounting frame 53 can be connected in a fastener connection, a clamping connection, etc., which is not limited. The circumferential direction of the grid 54 and the mounting frame 53 can be sealingly connected, for example, a second sealing gasket is arranged therebetween.

[0075] In this way, the connection between the grid 54 and the mounting frame 53 can be maintained by detaching the grid 54, which is simple in structure and strong in practicability.

[0076] Further, the louver 5A further includes a communication cavity 55 formed at the adjacent end surfaces of the grid 54 and the mounting frame 53, and a filter structure 56 is arranged in the communication cavity 55.

[0077] For example, the filter structure 56 is arranged in the communication cavity 55. Figure 7 and Figure 8As shown, exemplarily, the mounting frame 53 is provided with a receiving groove 531 and a sealing groove 532. The groove depth direction of the receiving groove 531 is perpendicular to the setting surface. The sealing groove 532 is used to arrange a second sealing gasket. The grid 54 is arranged at the groove opening 205 of the receiving groove 531. The grid 54 achieves a sealed connection at the contact end face with the mounting frame 53 through the second sealing gasket, thereby forming a communicating cavity 55 using the space corresponding to the receiving groove 531.

[0078] The inner end of the connecting cavity 55 is connected to the air duct cavity 3, and the outer end is connected to the external environment via the grille 54. A filter structure 56 is arranged inside the connecting cavity 55, which can enhance the filtration effect of the louvers 5A. Furthermore, the filter structure 56 can be maintained after the grille 54 is removed. The structure is simple and highly practical.

[0079] The filter structure 56 may include at least one of filter cotton and a dust filter. The filter structure 56 can be configured according to actual needs to meet corresponding filtration requirements.

[0080] Optionally, the louver 5A further includes a connecting cavity 55, which is formed at the adjacent end faces of the grid 54 and the mounting frame 53, and the second drainage structure 8 is connected to the connecting cavity 55.

[0081] In this embodiment, the drainage end of the second drainage structure 8 is connected to the external environment, and the rainwater entering the louver 5A can be at least partially collected by the connecting cavity 55 and then discharged through the second drainage structure 8.

[0082] It should be understood that when the louver 5A has a second drainage structure 8 and the air duct is equipped with a first drainage structure 7, the second drainage structure 8 may be connected to the first drainage structure 7 or may not be connected to the first drainage structure 7. When the two are not connected, the drainage end of the second drainage structure 8 can be directly connected to the external environment.

[0083] It should be understood that, in this embodiment, the above-mentioned filter structure 56 can also be arranged in the connecting cavity 55, and in conjunction with the second drainage structure 8, both the filtration effect and the drainage purpose can be achieved.

[0084] Optionally, in the above embodiments, the cabinet may further include an airflow drive device 6, which is installed inside the air duct cavity 3 or at the second ventilation structure 32 outside the air duct cavity 3.

[0085] like Figure 1 As shown, it illustrates the case where the airflow drive device 6 is installed outside the air duct cavity 3.

[0086] Specifically, the air flow driving device 6 comprises a driving member 61 and a mounting base 62, the driving member 61 is mounted on the mounting base 62, the mounting base 62 is connected with the cover 2, for example, the mounting base 62 is provided as a cylinder structure, one end of the cylinder structure corresponds to the position of the second vent structure, and the cylinder structure is sealingly connected with the cover 2, and the driving member 61 is mounted in the cover 2 through the mounting base 62. The driving member 61 is a component capable of driving the flow of gas. It can at least achieve the movement of the air flow in one direction. Subsequent exemplary descriptions will be provided.

[0087] It should be understood that when the air flow driving device 6 is directly mounted inside the air duct cavity 3, the mounting base 62 can be integrally or detachably provided with the cover 2, which is not limited.

[0088] When the air duct cavity 3 is provided with a plurality of second vent structures 32, generally, the air flow driving device 6 is provided at each second vent structure 32, which will not be described in detail here.

[0089] In a further optional solution, the driving member 61 is a single-direction rotating fan, when the fan rotates, the driving gas flows from the first vent structure 31 to the second vent structure 32.

[0090] In a further optional solution, the driving member 61 is a single-direction rotating fan, when the fan rotates, the driving gas flows from the second vent structure 32 to the first vent structure 31.

[0091] As shown in Figure 3 and Figure 5 In a further optional solution, the driving member 61 is a forward-reverse rotating fan, when the forward-reverse rotating fan rotates forward, the driving gas flows from the first vent structure 31 to the second vent structure 32, and when the forward-reverse rotating fan rotates reversely, the driving gas flows from the second vent structure 32 to the first vent structure 31.

[0092] In a further optional solution, the driving member 61 comprises two fans with opposite rotating directions, when one of the fans rotates, the driving gas flows from the first vent structure 31 to the second vent structure 32, and when the other fan rotates, the driving gas flows from the second vent structure 32 to the first vent structure 31.

[0093] In this way, the driving demand of the gas flow can be met, the structure is simple, and the practicality is strong.

[0094] It should be understood that in another embodiment, the cabinet plate body 1 and the cover body 2 can also be distributed in the horizontal direction, the cover body 2 is located on the side of the cabinet plate body 1 close to the outside of the cabinet, the first ventilation structure 31 is arranged on the cover body 2, and the second ventilation structure 32 is arranged on the cabinet plate body 1. In this case, if the cover body 2 is formed with the groove 21, at least one of the groove bottom wall 201, the second groove side wall 203 and the third groove side wall 204 is provided with the first ventilation structure 31. Details are not described herein.
