[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 3 shown, the fan housing of the embodiment of the present utility model includes: an outer frame 1, a wire harness adapter plate 4, and a waterproof cover plate 5. Among them, the outer frame 1 includes a fan accommodation cavity 11 and an adapter slot 12. The fan accommodation cavity 11 is used to accommodate the fan 2 and the fan wire harness 3. An air inlet hole 13 is provided on the cavity wall of the fan accommodation cavity 11; the wire harness adapter plate 4 is arranged in the adapter slot 12. The wire harness adapter plate 4 includes a first interface 41 and a second interface 42. The first interface 41 and the second interface 42 have an electrical connection relationship. The first interface 41 is used to connect the fan wire harness 3. The second interface 42 includes a plug-in part, and the plug-in part is located outside the slot opening of the adapter slot 12. The second interface 42 is used to connect the electrical device 6 for installing the fan 2; the waterproof cover plate 5 includes a mounting plate 51 and a plug-in sleeve 52. The mounting plate 51 fixedly installs the waterproof cover plate 5 at the slot opening of the adapter slot 12, and the plug-in sleeve 52 sleeves the plug-in part. Among them, the cavity wall where the air inlet hole 13 is opened can be adjusted according to the installation direction of the fan 2. The fan 2 can be one or more, and the size of the fan accommodation cavity 11 can be determined according to the size of the fan 2 to be accommodated, and this embodiment does not impose any restrictions.

[0031] It should be noted that when the fan 2 is fixed in the fan accommodation cavity 11, the gap between the fan 2 and the inner wall of the fan accommodation cavity 11 can be used to accommodate the fan wire harness 3, and the fan housing, the fan 2, and the fan wire harness 3 can form a complete fan assembly. When disassembling the fan assembly from the electrical device 6, only by separating the waterproof cover plate 5 fixed to the outer frame 1 from the electrical device 6 can the disassembly of the fan assembly be realized at one time; when it is necessary to replace and install the fan 2, there is no need to disassemble other components in the fan assembly except the fan 2, which can effectively reduce the maintenance time; only by inserting the plug-in sleeve 52 into the corresponding position of the electrical device 6 can the electrical connection between the second interface 42 and the electrical device 6 be realized. If the fan 2 is not powered on, it indicates that the plug-in sleeve 52 is not inserted in place, and the inconsistent installation can be found in time to avoid the risk of waterproof failure.

[0032] As Figure 3 shown, in an embodiment of the present utility model, a sealing ring 53 can be sleeved outside the plug-in sleeve 52. The sealing ring 53 is used to seal the gap between the plug-in sleeve 52 and the electrical device 6. When the plug-in sleeve 52 is inserted in place, the waterproof performance of the waterproof cover plate 5 can be improved through the compression of the sealing ring 53.

[0033] AsFigure 1 As shown, in an embodiment of the present utility model, a cover plate mounting hole 54 may be provided on the mounting plate 51, and the waterproof cover plate mounting screw 55 may fix and mount the waterproof cover plate on the notch of the adapter slot 12 through the cover plate mounting hole 54.

[0034] As Figure 1 shown, in an embodiment of the present utility model, a fan mounting portion 14 may further be provided in the fan accommodation cavity 11 for fixing the position of the fan 2 in the fan accommodation cavity 11. Specifically, the fan 2 may be fixed on the fan mounting portion 14 through the fan mounting screw 21. In some other embodiments of the present utility model, the fan mounting portion 14 may also be set as a snap-type mounting component to realize the fixation of the position of the fan 2, and this embodiment is not limited thereto.

[0035] In an embodiment of the present utility model, the adapter slot 12 may be filled with a sealant to realize the sealing between the adapter slot 12 and the waterproof cover plate 5 and prevent liquid from entering the adapter slot 12 through the gap between the adapter slot 12 and the waterproof cover plate 5.

[0036] As Figure 4 and Figure 5 shown, in an embodiment of the present utility model, a mounting buckle 15 is further provided on the outer frame 1. The mounting buckle 15 includes a first protrusion 151, a protrusion connecting portion 152, and a second protrusion 153 that are connected in sequence. The second protrusion 153 is connected to the outer frame 1 through a buckle connecting portion 16. The first protrusion 151, the protrusion connecting portion 152, and the second protrusion 153 form a notch. The buckle connecting portion 16 has elasticity, so that the mounting buckle 15 is in a first state or a second state. Among them, a mounting groove 61 that cooperates with the mounting buckle 15 is provided on the electrical device 6, and a limiting protrusion 62 is provided on the outer edge of the bottom of the mounting groove 61. When the mounting buckle 15 is in the first state and the notch accommodates the limiting protrusion 62, the first protrusion 151 is limited in the mounting groove 61 to realize the clamping connection between the outer frame 1 and the electrical device 6; when the mounting buckle 15 is in the second state, the vertical distance between the highest point of the limiting protrusion 62 and the top surface of the mounting groove 61 is suitable for the first protrusion 151 to horizontally enter and exit, so as to realize the installation and disassembly of the outer frame 1.

[0037] It can be understood that when the mounting buckle 15 is in the first state, the mounting buckle 15 and the buckle connecting portion 16 are both in a natural state (as Figure 5 shown), that is, a state not affected by other external forces; when the first protrusion 151 abuts against the top of the limiting protrusion 62, or the second protrusion 153 abuts against the disassembly tool for disassembling the outer frame, the elastic buckle connecting portion 16 will deform to drive the mounting buckle 15 into the second state (as Figure 4 shown), so that the first protrusion 151 can horizontally enter and exit between the limiting protrusion 62 and the top surface of the mounting groove 61.

[0038] By setting the installation buckle 15, simply pushing the outer frame 1 to be snap-connected with the electrical device 6 can fix the fan assembly including the housing on the electrical device, without the need to install the fan assembly by screwing, which can greatly reduce the on-site maintenance time. Moreover, the installation buckle 15 is arranged at the connection between the outer frame 1 and the electrical device 2, and it is difficult for ordinary people without special disassembly tools to make the installation buckle 15 enter the second state during disassembly, which has a certain anti-theft effect.

[0039] As Figure 5 shown, preferably, the number of the installation buckles 15 is two, and the corresponding number of installation grooves 61 is two. It can be understood that only when both installation buckles 15 are in the second state can the outer frame 1 be disassembled, ensuring the stability of the installation of the outer frame 1 and having a better anti-theft effect.

[0040] As Figures 4 to 6 shown, in an embodiment of the present invention, the outer frame 1 may be provided with a first disassembly groove 17 suitable for inserting a disassembly tool 7, and the first disassembly groove 17 is arranged on one side of the installation buckle 15. The disassembly tool 7 may be provided with a disassembly plate 71 adapted to the first disassembly groove 17. When the disassembly plate 71 is inserted into the first disassembly groove 17, a corner of the disassembly plate 71 can abut against the second protrusion 153 of the installation buckle 15, so that the buckle connection part 16 drives the installation buckle 15 to enter the second state, and then the outer frame 1 can be disassembled.

[0041] As Figures 4 to 6 shown, in an embodiment of the present invention, a second disassembly groove 18 may further be arranged in the first disassembly groove 17, and the second disassembly groove 18 is used to fix the relative positions of the disassembly tool 7 and the outer frame 1. The disassembly plate 71 of the disassembly tool 7 may be provided with a third protrusion 72 adapted to the second disassembly groove 18. When the disassembly plate 71 is inserted into the first disassembly groove 17, a corner of the disassembly plate 71 can abut against the second protrusion 153 of the installation buckle 15, and the third protrusion 72 on the disassembly plate 71 is snap-connected with the second disassembly groove 18. Therefore, only by applying a force to the disassembly plate 71 in the direction opposite to the setting direction of the first disassembly groove 17 can the third protrusion 72 drive the outer frame 1 to move along this direction, so as to realize the rapid disassembly of the outer frame 1, avoiding that when the outer frame 1 is moved, the disassembly tool 7 does not move synchronously with the outer frame 1, resulting in the installation buckle 15 returning to the first state and the smooth disassembly of the outer frame 1 cannot be realized.

[0042] As Figure 5 and Figure 6As shown, in a specific embodiment of the present utility model, the number of the first disassembly grooves 17 is two, and one second disassembly groove 18 is arranged in each of the first disassembly grooves 17. The disassembly tool 7 can correspondingly be provided with two disassembly plates 71, and corresponding third protrusions 72 are arranged on each of the disassembly plates 71. The disassembly tool 7 can also be provided with a disassembly connecting plate 73 for connecting the two disassembly plates 71, and a disassembly handle 74 can be arranged on the disassembly connecting plate 73, which is convenient for inserting or taking out the disassembly tool 7. When disassembling the outer frame 1, only by pulling the disassembly handle 74, the third protrusions 72 on the disassembly plates 71 can drive the outer frame 1 to move synchronously, and the disassembly is more convenient, faster, time-saving and labor-saving.

[0043] According to the fan housing of the embodiment of the present utility model, by designing the outer frame, the wire harness connecting plate and the waterproof cover plate for accommodating the fan and the fan wire harness as a whole, there is no need to separately equip a waterproof connector and an air inlet baffle, which simplifies the structural design and can effectively reduce the maintenance time at the same time. The electrical connection between the second interface and the electrical equipment can be realized only by inserting the plug-in sleeve into the corresponding position of the electrical equipment, and the installation inconsistency can be found in time to avoid the risk of waterproof failure.

[0044] Based on the fan housing of the above embodiment, the present utility model also proposes a fan assembly.

[0045] As Figure 1 shown, the fan assembly of the embodiment of the present utility model includes a fan 2, a fan wire harness 3 and the fan housing of any one of the above embodiments of the present utility model.

[0046] Since the fan assembly of the embodiment of the present utility model includes the above-mentioned fan housing, it also has the above-mentioned beneficial effects.

[0047] Based on the fan assembly of the above embodiment, the present utility model also proposes an electrical equipment.

Among them, the electrical equipment can be any equipment with heat dissipation requirements and suitable for air-cooled heat dissipation, such as a charging pile, especially a small DC charging pile.

[0049] Since the electrical equipment of the embodiment of the present utility model includes the above-mentioned fan assembly, it also has the above-mentioned beneficial effects.

[0050] In the description of the present utility model, the meaning of "a plurality of" is two or more than two, unless otherwise specifically defined.

[0051] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense.
