Recently, netizens in many areas have experienced sweltering weather in Sanfutian. Therefore, there are many Chimi natural wind fans with good quality and low price. As we all know, Zhimi is a millet eco-chain enterprise, and the products also have high cost performance characteristics. The price of the Chimi natural wind fan is only 599 yuan, and it can also blow the natural wind. It is very popular among many friends. So, what is the quality of this Chimi natural wind fan? Is the 599 yuan really worth it? Today, I will come Disassemble it.
After the first unpacking, you can start using it with a simple installation. The figure shows all the parts and installation tools of the product, including fan cover, fan blade, pole, base, remote control, battery, power cord, two screws And a hex wrench for fixing screws.
Zhimi natural wind fan continues the simple design language of Zhimi products, and the matte appearance texture can be well integrated into the home environment. The design can be said to be one of the most significant differences between Zhimi natural wind fan and other products. .
The first step in disassembly is to unscrew the screws for fixing the front and rear parts of the fan cover.
Remove the front cover by turning it gently.
The blade and the rear fan cover are removed in order from front to back. Each fixed part has a direction indication, and the operation of unscrewing has a very special process feeling.
The front disassembly steps are actually very easy to operate in daily life, so the daily cleaning parts will become very simple. Next, disassemble the fan body. First unscrew the four screws of the fan head and pull back. shell.
Inside the fan head, there are no messy components, but an unconventional black head bracket. The black cylindrical part that is connected together is the motor rear case. The top of the head bracket is four keys for micro-motion, which is used for adjustment. Wind speed, oscillating angle, natural wind, Wi-Fi connection, etc. Compared with the previous two products, the Zhimi natural wind fan body operation is more intuitive and rich.
2. Remove the motor back shell from the head bracket by unscrewing the screw.
The brushless DC motor used by the Chimi natural wind fan is provided by Meiya, with infinitely variable speed. Due to the large speed range and no frustration during shifting, the random algorithm of this product can be faithfully restored. come out.
Separate the head bracket. 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, regardless of structure or principle. Same as the screen opening and closing parts of the laptop.
Further separate the head bracket and remove all jumpers.
The electric control board is hidden on the back of the nose bracket and is effectively protected by a solid nose bracket.
Close-up of the electronic control board: The module with the 'mi' logo is a Wi-Fi module, which is used to support the connection of the Mijia APP, and to realize the intelligent control between the products of the Mijia platform.
Remove the bearing end cover housing, you can see the internal transmission gear used to control the swing head, the stepper motor is at the bottom.
After removing the gear, you can see the bearing below. Compared to the previous generation, the Chimi natural wind fan optimizes the bearing, making the left and right swing heads smoother. At the same time, the jumper is no longer connected from the outside, but directly from the bearing. The center passes through, avoiding the noise caused by the interference between the jumper and other components. The oscillating shaft has passed the swing test of up to 600,000 times to ensure reliable and durable.
Stepper motor close-up.
Use the hex wrench that comes with the product to unscrew the screws used to fasten the base and the pole, and separate the base and the pole.
Remove the base foot pad and hide the screw inside the foot pad.
After unscrewing all the screws, pry open the base housing.
Inside the base: Includes a power adapter, much like a Pogo Pin with a surprised face (used to connect and power the pole), weight plate, built-in lithium battery pack (with separate housing and logo), and for connection Battery power board.
Remove the battery screws. All unoccupied positions are filled with honeycomb ribs, which effectively increases the strength of the base.
Battery close-up: 33.6Wh capacity, 12V voltage, provided by Xiaomi ecological chain company Zimei, which is the manufacturer of rainbow battery.
Three metal weights close-up: In order to make the product more stable during operation, the weight of the base is artificially increased. Even so, the weight of the whole machine is still well controlled, only 3.6kg, which can be easily lifted and moved.
Pogo Pin assembly close-up: Positive and negative contacts, transferring power to the top of the head.
After opening the power adapter housing, you can see the power board.
The previous generation of users had a high voice for the remote control, and this time the Chimi natural wind fan was equipped as desired. The remote control has a compact and exquisite design. The connection method is not traditional infrared, but Bluetooth. Can be remotely controlled.
Remote control all parts show.
All components are displayed.
Under normal circumstances, electrical products generally only work hard on the outer casing, because only the outer casing will be seen, and often the internal is chaotic, as long as the function can be normal operation. In contrast, the smart rice natural wind fan makes People's eyes shine: Even the hidden components, there are exquisite and reliable modular design, including power adapter, head bracket, and built-in battery, all wrapped in separate shells, each component is taken out separately, both Can become an object, in this regard smartmi Zhimi has a deep effort.
From the point of view of workmanship and materials, the 599 yuan Chimi natural wind fan is still very conscience. Therefore, if the home needs a fan, consider the Chimi natural wind fan.
