As shown in FIG. 1 , the first motor 4 is preferably a brushless motor, and the fan main control board 7 is a core current main control board of the entire fan, which is used for controlling power on, power off, and gear shifting.

The utility model provides an outdoor hand-held fan (hereinafter referred to as a fan), which has the following advantages:

1: Can be carried in the bag, carry it in your pocket, where to go, where you can blow it, bring your own lithium battery, use the continuous working time for up to 8 hours, outdoor handheld fan can hang the rope, can be hung on the child's neck More convenient.

2: When returning to the company or home, inserting the fan head into the rotating base 13 can be used as a home desktop fan, the wind can reach 5M/s, and the desktop wind of the home is only 3M/S, the mute effect is only 50dB, far Far lower than the home desktop fan, the shaking head function and charging function can be realized on the rotating base 13.

3: When the fan head is inserted into the rotating base 13, the rotating base 13 is provided with the second motor 16, the internal supporting fixture, and the shaking head main control board 17, and the second motor 16 is powered by the energy storage lithium battery 9. Shake the head function.

4: There is an indicator light on the fan head. The power storage of the lithium battery 9 shows that 4 lights represent 25% of the power, 4 lights represent 100% of the power, 3 means 75%, 2 50% power, 1 25% power, no light represents 0 power, the method is to detect the voltage and current of the energy storage lithium battery 9 through the fan main control board 7 of the fan, and then control the display state of each light through conversion However, all other fans now have no power recognition function, which greatly improves the user experience.

5: The fan has a charging function. When the fan has no power, you can use the MRICO data cable to insert the bottom of the fan handle 11 to charge. At the same time, the fan can be used on the desktop to continue to use the fan blowing function. The data cable is very smooth. On the desktop, not the high impact of the data cable plug, the fan will not run and will not dump, increasing the friction between the fan and the desktop, solving a burden on other charging lines on the market. Beautiful.

6: The boot of the fan needs to be pressed for 3 seconds. This is calculated by the fan's main control board 7 of the fan. This solves many existing fans in the bag, in the user's bag, not in the pocket. Careful touch will turn on the phone, causing danger and reducing the battery life and battery capacity.

7: The power supply of the rotating base 13 is provided by the fan head at the top, and the inside of the fan head is provided with the energy storage lithium battery 9. When the fan head is inserted into the rotating base 13, the fan main control board 7 is boosted to 5V, and then passes through the fan main The output circuit of the control board 7 is connected to the USB plug 20 of the rotating base 13 through a USB socket, connected to the shaking head main control board 17 by the USB small board, the rotating base 13 receives 5V voltage, and the shaking head main control board 17 is processed by the main control circuit. Voltage and control commands, outputting the second motor 16, can realize the remote head/positioning control function, which can increase the comfort of the air flow and more experience of the consumer at the same time; solve the existing hand-held fan is limited to the outdoor Handheld without a way to use statically and without shaking your head.

8: The input and output of the boost chip on the fan main control board 7 are shared pins. Before the USB insertion, the boost chip is in the output boost mode. When the rotating base 13 is inserted into the USB 5V, the fan boost chip detects the 5V input. That is, it automatically switches to the charging mode (input mode). At this time, the USB charges the fan through the charging chip, and simultaneously supplies power to the rotating base 13. After the rotating base 13 receives the voltage, the rotating function is realized; this function is similar to the OTG of the mobile phone. Function, you can input charging, or you can supply power to the outside; so no matter what state, consumers can easily use the shaking function and charge the handheld fan at the same time, which improves the user-friendly design and experience.

9: The fan side support bars of the fan bottom case 2 are parallel to the table top, and the bottom of the fan handle 11 is in contact with the table top. The contact area is 7.2 square centimeters, and the gravity and friction force are far greater than the backward direction of the fan rotation. Thrust, at this time, the fan can be placed on the table side, and the fan will not move and will not fall when the maximum wind power is turned on. This solves the problem that the existing fan is lying on the desktop and will run and cannot be fixed.

10: When the fan is turned on, there is a fan mark on the button position. When the fan is turned off, the fan mark is turned off, which increases the recognition and beauty of the boot status, and solves the function of turning on the light of a conventional fan and even not recognizing the switch.

The above is a further detailed description of the present invention in conjunction with the specific preferred embodiments, and the specific implementation of the present invention is not limited to the description. For those skilled in the art to which the present invention pertains, a number of simple deductions or substitutions may be made without departing from the spirit and scope of the invention.
