1. Smartmi natural wind fan is a smart floor fan product launched by Xiaomi's ecological chain company smartmi technology. It is worth noting that the 599 yuan Zhimi natural wind fan is currently available in JD’s self-operated channels. There is no need to squeeze and grab it. It can be said to be good news for the sweltering dog days. Given that everyone is paying more attention to this product, today we conducted a complete dismantling experience on it to see how it is quality.

The picture shows all the parts and installation tools of the product, including fan cover, fan blade, pole, base, remote control, battery, power cord, two small and large screws, and hexagonal wrench for fixing screws.
3. Zhimi natural wind fan continues the simple design language of Zhimi products, and the matte appearance and texture can be well integrated into the home environment. The appearance design can be said to be one of the most significant differences between the Zhimi natural wind fan and other products.

8. Inside the fan head, there is no messy arrangement of components, but an unconventional black machine head bracket. The black cylindrical part connected together is the motor rear shell. There are four buttons on the top of the head support to adjust the wind speed, head swing angle, natural wind, Wi-Fi connection, etc. Compared with the two buttons of the previous generation product, the operation of the Zhimi natural wind fan is more intuitive and rich.
9. Separate the back shell of the motor from the head support by unscrewing the screws.
10. The brushless DC motor used in the Zhimi natural wind fan is provided by Minebea. It has the ability of continuously variable speed. Because of the large speed range and no frustration when changing the speed, it can change the random algorithm of this product to the natural wind Restored faithfully.
11. Separate the head support. The removed part in the figure is the damping shaft, which is used to adjust the pitch angle of the fan. Because of the additional springs and screws between the two hinges, the fan can stay at any desired angle, and the structure and principle are the same as the opening and closing parts of the laptop screen.
12. Further separate the machine head bracket and unplug all jumpers.
13. The electric control board is hidden on the back of the machine head support and is effectively protected by the firm machine head support.

15. Remove the bearing end cover shell, you can see the internal transmission gear used to control the swing head, and the stepper motor is at the bottom.
16. After removing the gear, you can see the bearing below. Compared with the previous generation products, the Zhimi natural wind fan has optimized the bearings to make the left and right swing heads more smooth. At the same time, the jumper wire is no longer connected from the outside, but directly passes through the center of the bearing, avoiding noise caused by interference between the jumper wire and other components. The swing head shaft has passed 600,000 swing head experiments to ensure reliability and durability.

26. After opening the power adapter shell, you can see the power board.
27. The previous generation of users have a high voice for the remote control, but this time the Zhimi natural wind fan is equipped as desired. The remote control has a small and exquisite design. The connection method is not traditional infrared, but Bluetooth. It can be remotely controlled without aiming at the fan.
28. All parts of the remote control are displayed.
29. All components are displayed.
30. Under normal circumstances, electrical products generally only put effort on the shell, because only the shell can be seen, and the interior is often messy, as long as the function can be operated normally. In contrast, the Zhimi natural wind fan is eye-catching: even the hidden components have a sophisticated and reliable modular design, including the power adapter, the head bracket, and the built-in battery. Each component can be taken out separately to become an object. Smartmi has worked hard in this regard. It can be said that the Zhimi natural wind fan is a particularly "tolerable disassembly" product.
31. In view of the same workmanship and materials, it is extremely difficult to control the price in the mainstream range.
