[0079] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0080] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0081] This utility model proposes a wall-mounted, workstation-type circular fan with an oscillating function, such as... Figures 1 to 25 As shown, a preferred embodiment of the wall-mounted circular fan with oscillation function of this utility model includes: a wall-mounting component 10, an oscillation box component 20, a U-shaped bracket component 30, an angle limiting plate 40, and a fan component.

[0083] In this embodiment, the wall-mounting component 10 includes: a multi-functional mounting bracket base plate 101, a reinforcing rib 102, a square tube 103, a swing-up box mounting plate 104, and a wall-mounting component anti-fall screw 105.

[0084] The bottom center of the multifunctional mounting bracket base plate 101 is provided with a square tube positioning hole 1011, and multiple sets of multifunctional mounting holes 1012 are provided around the square tube positioning hole 1011. The upper and lower sides of the multifunctional mounting bracket base plate 101 are provided with reinforced chamfered edges 1013. The square tube 103 is inserted into the square tube positioning hole 1011 and then welded to achieve a reliable connection, which can effectively reduce the positioning error caused by welding.

The wire hole 1021 reduces the weight of the accessory and also allows for wire threading and winding. The reinforcing rib 102 has a streamlined design and a short arched curve 1022 on its inner side. This reduces welding during the reinforcement process, and the arched curve 1022 increases the rigidity of the accessory and improves its appearance.

The U-shaped bracket mounting plate 302 is provided with U-shaped bracket flanges 3021 on both sides to cooperate with the U-shaped bracket 301. The U-shaped bracket mounting plate 302 is provided with an anti-fall screw mounting hole 3022 and a second bearing sleeve screw clearance hole 3025. The U-shaped bracket 301 and the U-shaped bracket mounting plate 302 are positioned and welded through the first bearing sleeve screw clearance hole 3015 and the second bearing sleeve screw clearance hole 3025. The U-shaped bracket anti-fall screw 303 passes through the anti-fall screw mounting hole 3022 of the mounting plate 302 and the anti-fall screw hole 3013 of the U-shaped bracket 301.

[0102] The U-shaped bracket assembly 30 consists of a U-shaped bracket 301 and a U-shaped bracket mounting plate 302, which are positioned and welded together through the first bearing sleeve screw clearance hole 3015 and the second bearing sleeve screw clearance hole 3025. The U-shaped bracket mounting plate 302 has two U-shaped bracket flanges 3021 on both sides to cooperate with the U-shaped bracket 301. The U-shaped bracket anti-fall screw 303 passes through the anti-fall screw mounting hole 3022 of the U-shaped bracket mounting plate 302 and the anti-fall screw hole 3013 of the U-shaped bracket 301, providing secondary protection. This screw provides a second layer of protection, preventing the fan body below the U-shaped bracket 301 from falling and causing an accident after the components detach from the weld.

The second bearing sleeve screw clearance hole 3025 and the sway bearing sleeve mounting hole 3026 can effectively avoid the obstruction of the fastener head, making the installation simple.

[0105] Furthermore, in this embodiment, the angle limiting plate 40 is provided with a cylindrical connecting hole 4011, a U-shaped bracket mounting hole 4012 and an angle limiting mounting hole 4013.

[0106] In this embodiment, screws are inserted into the connecting holes 3011 of the U-shaped bracket 301 and installed in the U-shaped bracket mounting holes 4012 of the angle limiting plate 40. Then, screws are inserted into the angle limiting holes 3012 of the U-shaped bracket 301 and installed in the angle limiting mounting holes 4013 of the angle limiting plate 40, thereby realizing the adjustment of the pitch angle. This structure of using screw holes for angle adjustment is more robust and can effectively prevent the fan from turning around during long-term operation. The use of a double-screw angle adjustment structure in this embodiment further improves the reliability of the fan.

[0107] Furthermore, the fan assembly includes a housing 50, a motor support plate 60, a motor 70, a fan blade 80, a fan grille 90, and an external junction box assembly 100.

[0108] In this embodiment, screws are inserted into the cylindrical connecting hole 4011 of the angle limiting plate 40 and installed in the angle connecting plate mounting hole 5011 of the housing 50. The angle limiting plate 40 is U-shaped and is connected to the housing 50 by four screws, which increases the force-bearing area of ​​the angle connecting plate. The force is more even when the fan is running, which further improves the reliability of the fan.

[0109] Furthermore, in this embodiment, the housing 50 is internally provided with two annular trapezoidal ribs 5013, which effectively strengthens the main rigidity of the housing and makes the connection between the internal components and the motor support plate more reliable. The housing has annular rolled edges 5014 on both sides, which greatly strengthen the edges of the housing, reducing deformation caused by collisions during normal transportation. Furthermore, when using self-tapping screws for fan installation, the rolled edges can shield sharp corners, protecting the user from injury. This bidirectional reinforcement structure further enhances the reliability of the fan. The housing is also provided with angle connecting plate mounting holes 5011 and motor mounting plate mounting holes 5012.

[0110] Furthermore, in this embodiment, the motor support plate 60 has two rectangular reinforcing ribs 6014 inside, and C-shaped folded edges 6013 on both sides for structural reinforcement, further improving the stability of the product. Screws are inserted into the motor support plate mounting holes 5012 of the housing 50 to install the motor support plate 60 into the housing mounting holes 6011. A total of four plates are connected in an X-shape. The motor 70 has four motor mounting plates 7011 on its four sides. Screws are used to install the motor mounting holes 6012 of the motor support plate 60 and the motor support mounting holes 7012 of the motor 70. A motor cable outlet sleeve 7013 is provided at the rear of the motor, providing a certain degree of waterproofing. The fan blade 80's fan shaft hole 8014 is installed into the motor shaft extension 7014; the blades 8011 are made of aluminum, with three blades, and are fixed to the blade support plate 8013 using rivets 8012. The fan mesh 90's fan mesh mounting holes 9011 are installed on the housing annular rolled edge 5014. The high-strength X-shaped connection and the integrated design of reinforced components enhance the reliability of the fan and provide structural reinforcement.

[0111] Furthermore, in this embodiment, the external junction box assembly 100 includes an external junction box base plate 1001, an external junction box body 1002, a cable outlet sleeve 1003, a speed control switch 1004, and a swivel switch 1005.

[0112] The external junction box base plate 1001 has double circular mounting holes 10012 on both sides, with the larger hole at the bottom and the smaller hole at the top. The external junction box body 1002 is mounted on the junction box threaded mounting hole 10011 through the junction box mounting hole 10021. The cable outlet sleeve 1003 is mounted on the cable outlet sleeve mounting hole 10023. The speed control switch 1004 is mounted on the speed control switch mounting hole 10025, and the oscillating switch 1005 is mounted on the oscillating switch mounting hole 10024. Waterproof sealant 10022 is affixed to the bottom of the junction box body, providing a certain degree of waterproofing. Furthermore, because the center of the rear mounting surface of the external junction box base plate 1001 protrudes upwards, the contact area between the integrated wall mount and the wall is reduced, allowing it to fit more closely to the wall after mounting. This embodiment uses a riveted structure, further improving the reliability of the fan.
