DETAILED DESCRIPTION

[0022] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] The utility model provides a kind of angle-adjustable fan as Figs. 1-3 As shown in a kind of angle-adjustable fan, comprising:

[0024] Base 1, the top center of the base 1 is equipped with clamping groove 3 and clamping groove 3 is clamped and fixed with support 2, the both ends in support 2 are rotatably connected with fan 4 by adjusting piece, the adjusting piece is damping pivot, the damping pivot includes damper 6, the damper 6 is equipped with two groups and is respectively located in the both ends of support 2, the both ends of fan 4 are equipped with damping wear block 7, and the damper 6 is rotatably connected with damping wear block 7;

[0025] Mounting box 8, the mounting box 8 is equipped in base 1, for installing sound.

[0026] The damping wear block 7 is equipped with connecting rod 9, and one end of connecting rod 9 is connected with fan 4, and the other end is rotatably penetrated through damper 6 and connected with rotating cap 10.

[0027] The bottom of base 1 is fixed with bottom plate 11 by screw, and the top of bottom plate 11 is connected with battery box 12 for installing battery.

[0028] The bottom of mounting box 8 is connected with several fixing ears 13, and the mounting box 8 is fixed with screw hole 14 on the surface of battery box 12 by screw penetrating through fixing ear 13, when battery needs to be replaced, only need to unscrew the screw on bottom plate 11 and battery box 12, old battery can be conveniently taken out and new battery is installed, if sound or other internal components fail, corresponding screw can also be disassembled, base 1 is easily opened, and the failed components are checked, repaired or replaced.

[0029] The front and rear ends in base 1 are respectively equipped with control panel 15 for controlling fan 4 and sound, the surface of two groups of control panel 15 is electrically connected with display screen 16, the surface of two groups of control panel 15 is equipped with several control switches 17, the top of base 1 is equipped with two groups of loudspeakers 18, the sound, fan 4, control panel 15 are electrically connected with battery, two groups of control panel 15 are as core control unit, one group is responsible for controlling the functions such as wind speed and running mode of fan 4, and the other group controls the operations such as playing, pausing, volume adjusting and track switching of sound, so that user can easily realize various operations of fan 4 and sound through several control switches 17 on the surface of control panel 15.

[0030] The angle-adjustable fan, the battery in the battery box 12 in the base 1 can be used as a power supply to provide power for the motor of the fan 4 to drive the fan 4 to work, and the rotating speed of the fan 4 can be adjusted through the corresponding control switch 17 on the control panel 15, and the user can select different wind speed gears according to the actual needs to meet different cooling needs.

[0031] When the user applies external force to rotate the fan 4, the damping wear-resistant block 7 rotates relative to the damper 6, and the internal structure of the damper 6 is designed to generate a certain resistance during rotation. This resistance can not only ensure that the fan 4 remains stable at the current angle when there is no external force, but also allows the fan 4 to smoothly rotate to a new angle when subjected to appropriate external force. For example, when the user wants to adjust the air supply direction of the fan 4 upward, holds the fan 4 shell and applies a certain torque upward, the fan 4 will overcome the resistance of the damper 6. When the fan 4 adjusts the angle and applies a certain force, it can slowly rotate under the cooperation of the damper 6 and the damping wear-resistant block 7 until it reaches the angle required by the user. At this time, due to the friction between the damper 6 and the damping wear-resistant block 7, the fan 4 will be stable at the new angle position and will not deviate due to its own vibration or slight external force interference, thereby realizing the precise and stable angle adjustment function.

[0032] The sound installed in the installation box 8 is also powered by the battery. When the user operates the sound through the control switch 17 on the control panel 15, the control panel 15 will send a corresponding electrical signal to the sound device and convert it into an analog audio signal. After power amplification by the amplification circuit, the analog audio signal is transmitted to the loudspeaker 18, so that the electrical signal can be converted into a sound signal and played out. During the entire process, the display screen 16 will display the working status of the sound according to the instructions of the control panel 15, such as volume, playing track, playing mode and other information, to facilitate the user to understand and operate.

[0033] The battery in the battery box 12 can enter a charging state to store energy when connected to an external power source (such as a household power socket). When the device is in a use scenario without external power, the battery will automatically switch to a power supply mode. The battery provides stable DC power to the fan 4 motor, sound circuit and other device components through the internal discharge circuit, ensuring the continuous operation of the device.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
