Detailed Implementation
[0016] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0017] like Figures 1-9As shown, this utility model embodiment provides a novel fan, including: a housing 1, an airflow guide frame 2 fixed inside the housing, a fan blade assembly 3 connected to the airflow guide frame, and a PCB board 4; it also includes: a first mounting shell 6 and a second mounting shell 7 located on both sides of the housing 1; two sets of rotating components 8 for rotatably connecting the first mounting shell 6 and the second mounting shell 7 to the two sides of the housing 1; a U-shaped bracket 9 connected to the first mounting shell and the second mounting shell, with the housing disposed inside the U-shaped bracket; and a power component 5 for driving the housing 1 to rotate relative to the U-shaped bracket. Here, the housing is fixedly connected to the airflow guide frame 2.
[0018] like Figures 1-5 As shown, specifically, in this embodiment, the U-shaped bracket 9 includes two parallel U-shaped side brackets 901 and two parallel upper crossbars 902 for connecting the two U-shaped side brackets together; the U-shaped bracket is integrally formed from the two U-shaped side brackets and the two upper crossbars; the two U-shaped side brackets are spaced apart; because there is a large gap between the two U-shaped side brackets, it is more stable when placed; at the same time, the bottom and one side of the U-shaped bracket 9 are provided with several feet 14, that is, in addition to the bottom of the U-shaped side brackets being used as the bottom of the fan for placing the fan, using one side of the two U-shaped side brackets as the bottom of the fan can also meet the usage requirements, thus making the application range wider, such as... Figure 2 As shown.
[0019] like Figure 6 As shown, the PCB board 4 is disposed inside the first mounting shell 6; the first mounting shell 6 includes a first front cover 601 and a first rear cover 602 connected thereto; the first front cover has four mounting holes 601a, each mounting hole has a button bracket 10 in contact with the PCB board 4, and each button bracket has a button 11 with its surface located outside the first front cover; two uprights located on one side of the two U-shaped side brackets 901 pass through the first mounting shell and are fixedly connected to the first mounting shell, that is, the first front cover 601 here is the control panel of the fan, and various buttons are set on the first front cover for controlling the fan.
[0020] More specifically, the rear surface of the first rear cover 602 is provided with a first cylindrical protrusion 602a; the outer shell 1 is formed by connecting a left cover 101 and a right cover 102 with a semi-circular cross-section; the two sides of the outer shell are the left side and the right side of the outer shell; a mounting part 103 is provided on each of the left side and the right side of the outer shell, and a mounting cover plate 103a is provided in the mounting part; the rear end of the outer shell is provided with a rear cover 12.
[0021] In this embodiment, the two sets of rotating components 8 have the same structure; both include a rotating bearing 801 and a cylindrical rotating shaft 802. During installation, the rotating bearing of the rotating component on the right is fixed inside the first rear cover 602, and one end of the cylindrical rotating shaft is fixed to the mounting cover plate 103a located on the right side of the outer casing; the other end of the cylindrical rotating shaft 802 is inserted into the rotating bearing; the mounting part on the right is inserted into the first protrusion. Here, the cylindrical rotating shaft 802 and the mounting cover plate 103a are integrally formed, and the mounting cover plate 103a is integrally formed with the mounting part 103 and the outer casing 1.
[0022] like Figure 6 As shown, the second mounting housing 7 includes a second front cover 701 and a second rear cover 702 connected thereto; two uprights located on the other side of the two U-shaped side brackets 901 respectively pass through the second mounting housing and are fixedly connected to the second mounting housing; a cylindrical second protrusion 702a is provided on the rear surface of the second rear cover 702; the rotating bearing of the rotating assembly located on the left side is fixed inside the second rear cover 702, one end of the cylindrical rotating shaft 802 is fixed to the mounting cover plate 103a located on the left side of the housing, and the other end of the cylindrical rotating shaft 802 is inserted into the rotating bearing; the mounting part located on the left side is inserted into the second protrusion. The aforementioned first protrusion and second protrusion 702a have the same shape and function.
[0023] Here, as Figure 6 As shown, the power assembly 5 includes a motor 501 located in the mounting portion 103 on the right side of the housing and offset from the center of the mounting portion; a gear 502 located in the first rear cover 602 and connected to the motor output shaft; and an arc-shaped rack portion 503 fixed in the first rear cover 602 and meshing with the gear. With this structure, the motor 501 is eccentrically positioned. When the motor 501 starts, it drives the gear 502 to rotate. The arc-shaped rack portion 503 meshing with the gear 502 rotates relative to the gear. Because the first rear cover 602 is fixedly connected to the U-shaped bracket 9, the first rear cover 602 and its connected components cannot rotate. Therefore, the motor 501, the housing 1, and the components inside the housing 1 rotate relative to the U-shaped bracket 9, thereby achieving the fan's oscillation function. An oil pan 15 is also provided inside the first rear cover 602, covering the gear 502 and the arc-shaped rack portion 503.
[0024] The fan blade assembly 3 includes a fan blade 301. Since fan blade assemblies are commonly used in this type of fan and are existing technology, they will not be described in detail here.
[0025] To enhance the lighting function, an lighting assembly 13 is also included, housed within the axial perforation of the wind deflector 2. The lighting assembly includes a middle frame 1301 located at the front opening of the axial perforation, a lampshade 1302 within the middle frame, a lampshade mounting bracket 1303 located within the rear opening of the middle frame and connected to the lampshade, a reflector 1304 within the lampshade, a flexible light strip 1305 fitted onto the lampshade, a COB light board 1306 located behind the reflector, and a light mirror 1307 located in front of the reflector. The COB light board and light mirror are located within the lampshade 1302. The flexible light strip 1305 is electrically connected to the PCB board 4.
