Description

Technical Field

[0001] This utility model belongs to the field of fan technology, specifically relating to a directional adjustment fan with a display function. Background Technology

[0002] A fan, also known as an electric fan, is a household appliance that uses an electric motor to drive the fan blades to rotate, thereby accelerating the circulation of air. It is mainly used for cooling and ventilating the air and is widely used in homes, classrooms, offices, shops, hospitals, hotels, and other places. Fans can be divided into floor fans, ceiling fans, and table fans. Table fans are relatively small and are usually placed on a table for use.

[0003] According to the patent announcement number CN216665988U, which describes a table fan with omnidirectional rotation, this patent is known prior art. Although this patent has the advantage of being able to rotate the fan head to easily adjust the airflow direction, the technical solution of this patent still has the following defects in actual use: when the fan is in use, it is difficult for people to clearly understand the current operating status information of the fan (such as the wind speed setting and the running time), which will cause inconvenience to the use of the fan. Therefore, we propose a rotation adjustment fan with display function. Utility Model Content

[0024] In this embodiment, when the motor 12 is powered on, the motor 12 will drive the fan blade body 13 to rotate, which can generate wind. The front cover 14 and the rear shell 11 are connected in a detachable manner, and the metal support tubes 3 on both sides of the rear shell 11 are used to support the fan blade assembly 1.

[0025] Please see Figure 1 , Figure 3 and Figure 4A plastic part 4 is provided at the bottom end of the metal support tube 3, and the metal support tube 3 and the plastic part 4 are fixedly connected by a fixing block 5. A control PCB board 6 is fixedly installed inside the plastic part 4. The fixing block 5 is located inside the plastic part 4, and the side of the plastic part 4 is provided with an insertion port for the metal support tube 3. The fixing block 5 and the metal support tube 3 are inserted into each other. The top of the base 2 and the bottom of the plastic part 4 are movably connected by a rotating shaft 7. A rotating shaft fixing part 8 is provided at the bottom end of the rotating shaft 7. The plastic part 4 includes an upper shell 41, a lower shell 42 and a display screen 43. The bottom of the lower shell 42 is connected to the rotating shaft 7. The display screen 43 is installed on the front of the upper shell 41, and the display screen 43 is electrically connected to the control PCB board 6.

[0026] In this embodiment, when the metal support tube 3 is pushed, the metal support tube 3 will apply force to the plastic part 4, causing the rotating shaft 7 to rotate. At this time, the plastic part 4 and the base 2 will rotate, causing the fan blade assembly 1 to turn. The display screen 43 on the front of the plastic part 4 will also turn with the plastic part 4, which makes it easier for people to observe the information displayed on the display screen 43.

[0027] The display screen 43 can be used to display the information content controlled by the control PCB board 6 (such as running time, fan speed level, etc.), so as to facilitate people's use of the fan. In this application, the display screen 43 and the control PCB board 6 are existing public technologies for processing and displaying information, which will not be described in detail here.

[0028] Please see Figure 3 , Figure 5 and Figure 6 The base 2 includes a top shell 21, a bottom shell 22, and a battery 23. The battery 23 is located between the top shell 21 and the bottom shell 22. A button 24 is fixedly installed on the front of the top shell 21. A button PCB board 25 is connected to the back of the button 24. A charging PCB board 26 is fixedly connected to one side of the battery 23. A charging and discharging interface 27 is connected to one side of the charging PCB board 26. Decorative parts 28 are provided around the top shell 21 and the bottom shell 22. A pivot 7 is located in the middle of the top shell 21. A hook 9 is located at the bottom of the bottom shell 22. The bottom of the base 2 is movably connected to the hook 9.

[0029] In this embodiment, by pressing button 24, the button PCB board 25 is activated, thereby adjusting the operating status and wind speed of the fan. The charging and discharging interface 27 can be used to charge or discharge the battery 23. At the same time, the battery 23 can provide power to the motor 12, the display screen 43, the control PCB board 6 and the button PCB board 25. The fan can be suspended using the hook 9.

[0030] In the above scheme, it should be noted that: the control method of the motor 12 by the button 24 and the button PCB board 25 in this application is the publicly disclosed technology of the existing fan structure, and the information processing and display method between the display screen 43 and the control PCB board 6 is also the publicly disclosed technology. At the same time, the way the battery 23 supplies power to the motor 12, the display screen 43, the control PCB board 6 and the button PCB board 25 and the related circuit wire arrangement and connection method are also existing technologies, and will not be described in detail here.

[0031] The working principle and usage process of this utility model are as follows: First, the external circuit is connected by the charging and discharging interface 27, so that the electrical energy in the external circuit can be transmitted to the battery 23 through the charging PCB board 26, thereby facilitating the charging of the battery 23.

[0032] Next, press button 24 to control the circuit of motor 12 using button PCB board 25, so that motor 12 runs due to power supply. At this time, motor 12 will drive fan blade body 13 to rotate, which can generate wind. The fan speed can also be adjusted by operating button 24.

[0033] Finally, when the metal support tube 3 is pushed, it will exert force on the plastic part 4, causing the rotating shaft 7 to rotate. At this time, the plastic part 4 and the base 2 will rotate, causing the fan blade assembly 1 to turn. The display screen 43 on the front of the plastic part 4 will also turn with the plastic part 4, which makes it easier for people to observe the information displayed on the display screen 43.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
