Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a wall fan that is easy to install. Background Technology

[0002] A wall fan is a small electric fan installed on a wall to save space. It is characterized by its convenience, practicality, and aesthetic appeal. Wall fans are divided into two types: directional and oscillating. Oscillating fans can oscillate to blow air, providing a wide airflow and strong airflow. Wall fans are commonly used in canteens, restaurants, factories, and similar locations.

[0003] Currently, existing wall fans are usually installed by bolting the entire fan directly to the wall. Therefore, when the wall fan needs to be disassembled for maintenance, the entire fan needs to be removed, which is quite troublesome. In addition, the installed wall fan cannot adjust the airflow angle, which does not meet people's needs. Utility Model Content

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0020] like Figures 1-4 The wall fan shown is easy to install and includes a fan head 1, a control panel housing 2 for controlling the operation of the fan head 1, and a support frame 3 for supporting and fixing the control panel housing 2. The support frame 3 includes a flip plate 4 and a fixed plate 8. Vertical slots 5 are provided on the left and right sides of the front end of the flip plate 4. The lower end of the vertical slot 5 is provided with a limit plug 9. Flange inserts 6 are provided on the left and right sides of the control panel housing 2. The two flange inserts 6 are inserted into the two vertical slots 5 respectively and are limited and fixed by the limit plugs 9. A first rotating shaft 7 is fixedly provided on the rear side of the lower end of the flip plate 4. The first rotating shaft 7 is rotatably hinged to the fixed plate 8. The fixed plate 8 is fixed to the wall, and a flipping device is also provided on the fixed plate 8 to drive the flip plate 4 to flip back and forth with the first rotating shaft 7.

[0021] Based on the above structure, firstly, flange inserts 6 are provided on the left and right sides of the control panel housing 2. During installation, the flange inserts 6 can be directly inserted into the corresponding vertical slots 5. The process is simple, time-saving, and labor-saving, greatly improving the convenience of wall fan installation and disassembly. In addition, the tilting plate 4 can be adjusted up and down by tilting device, thereby adjusting the up and down blowing angle of the fan head, expanding the working range of the wall fan and improving the practicality of the wall fan.

[0022] See Figure 3 , Figure 4 As shown, a limiting component is provided at the upper end of the vertical slot 5 to confine the flange insert 6 within the vertical slot 5. The limiting component includes a stop block 21 inserted at the rear side of the vertical slot 5. A baffle 22 is also provided at the rear side of the flip plate 4. A spring 23 is connected between the rear end of the stop block 21 and the baffle 22. The flange insert 6 is fixed between the stop block 21 and the limiting plug 9. Thus, when the flange insert 6 is inserted into the vertical slot 5, the lower end is limited by the limiting plug 9, and the upper end is limited by the stop block 21, thereby firmly fixing the control panel housing 2. When the control panel housing 2 needs to be removed, the stop block 21 is retracted, and the flange insert 6 can move upward out of the vertical slot 5, achieving quick disassembly.

[0023] Furthermore, the rear ends of the two stop blocks 21 are connected to a connecting plate 41, so that by driving the connecting plate 41 to move, the two stop blocks 21 on both sides can be driven to move synchronously, which facilitates the disassembly of the control panel housing 2.

[0024] A guide post 51 extending along the front and back is provided on the baffle 22, and the guide post 51 passes through the connecting plate 41.

[0025] Furthermore, a handle 81 is provided at the upper end of the control panel housing 2.

[0026] See Figure 4 As shown, a guide slope 31 is provided at the upper end of the stop block 21 located in the vertical slot 5, so that when the flange insert 6 is inserted into the vertical slot 5, it can first abut against the guide slope 31, allowing the stop block 21 to retract, thereby facilitating the installation of the control panel housing 2.

[0027] See Figures 2-4 As shown, the flipping device includes a second rotating shaft 61 rotatably disposed on the front side of the fixed plate 8 and located above the first rotating shaft 7. A swing rod 62 is spaced apart on the second rotating shaft 61. A column 63 is disposed at the lower end of the swing rod 62. Vertical grooves 64 are provided on both the left and right sides of the flipping plate 4. The column 63 is movably disposed in the vertical grooves 64. A turbine 65 is disposed at one end of the second rotating shaft 61. A worm gear 66 cooperating with the turbine 65 is also disposed on the fixed plate 8.

[0028] Furthermore, a protective shell 71 is provided on the fixed plate 8, and the turbine 65 and the worm 66 are both located inside the protective shell 71, and the front end of the worm 66 extends out of the protective shell 71 and is provided with an internal hexagon head 72.

[0029] When the flipping device is working, the second rotating shaft 61 can be driven to rotate by using a wrench and an Allen head 72. The rotation of the second rotating shaft 61 drives the swing rod 62 to swing. The column 63 on the other end of the swing rod 62 moves in the vertical slide groove 64, thereby causing the flipping plate 4 to swing around the first rotating shaft 7 as the axis, so as to adjust the blowing angle of the fan head 1.

[0030] It is worth mentioning that through the cooperation of the turbine 65 and the worm gear 66, the second rotating shaft 61 can be driven to rotate, and it also has a self-locking function. When the worm gear 66 stops rotating, the second rotating shaft 61 also stops rotating, ensuring the stability of the flipping plate 4 after the flipping angle.

[0031] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
