Xiaomi’s modern smart humidifiers are not just appliances, but complex devices with sophisticated ergonomics and minimalist design. However, it is the lack of visible screws and hidden fasteners that often confuse owners when it comes time to replace filters, clean the ultrasonic membrane or eliminate clogs. Proper disassembly allows you to extend the life of the gadget and avoid costly repairs in the service center.
Many users are afraid of damaging fragile plastic or breaking the tightness of the case, which can really lead to the failure of electronics. In this article, we will take a detailed look at the process of dismantling various models, including the Mi Smart Humidifier and Deerma, focusing on safe removal of the tank and access to internal components.
It is worth noting that the design of Xiaomi devices is constantly improving, so the methods of mounting may vary slightly depending on the year of release. The basic principles remain similar, but attention to detail plays a crucial role here. Before starting any manipulations, be sure to disconnect the device from the power grid to eliminate the risk of short circuit or electric shock when working with wet components.
Workplace preparation and necessary tools
Before you start dismantling, you need to have a comfortable workspace with good lighting, you need a clean, dry surface covered with soft cloth to avoid scratching the glossy plastic of the case during operation. The absence of dust and dirt in the work area is critical, because getting small particles inside the device can cause the ultrasonic generator to break.
To disassemble most Xiaomi humidifier models, you’ll need a minimal set of tools that every homemaker will have, including a small cross screwdriver, often referred to as a PH0 or PH1, as the screws in these devices are usually small and hidden under decorative plugs.
- 🔧 Cross screwdriver (sizes) PH0, PH1) screw-up.
- 🧤 Plastic blade or mediator for gently opening latches without damage.
- 🧹 Dry lilaless fabric for cleaning internal surfaces.
- 🔦 Lighting for illuminating hidden screw attachment locations.
Using metal tools such as knives or flat screwdrivers to tweak plastic panels is highly discouraged as it is almost guaranteed to result in chipping.Plastic tools or old bank cards are ideal for working with body clips, providing the necessary effort without risking damage to the aesthetics of the device.
☑️ Checking disassembly readiness
Dismantling of water tank and upper cover
The first step in any disassembly is to separate the water tank from the main base. In the Mi Smart Humidifier series, the top is removed by a simple turn or lift, depending on the specific modification. It is important to act smoothly, without undue effort, so as not to break the guides, which can become brittle after prolonged contact with water and temperature changes.
If the tank is not easily removed, check if it is stuck due to scaling or deformation of the seals. Sometimes it helps a slight tap on the walls or gently scrolling in different directions. Inside the tank is often a floating water level sensor that must be removed before washing, so that it does not get lost or damaged.
⚠️ Warning: Never attempt to forcefully tear off a jammed tank as you may damage the valve's water supply mechanism, leading to leaks on the table or floor.
Once the tank is removed, examine its interior for biofilm or lime plaque, which is the most common cause of unpleasant odors and reduced efficiency. A citric acid solution can be used for deep cleaning, but then thoroughly wash the container with clean water several times.
💡
For a remote plaque inside the tank, use a soft sponge and a solution of warm water with the addition of a small amount of vinegar, leaving for 30 minutes.
Disassembly of the base and access to the ultrasonic membrane
The base of the humidifier contains all key electronic components, including an ultrasonic membrane that converts water to steam. To get to it, you need to flip the device upside down and find hidden screws. In new Xiaomi models, they are often covered with rubber legs or stickers with technical information that need to be carefully tampered with.
After unscrewing all visible fasteners, the body can still hold onto plastic latches around the perimeter. Use a plastic blade to gently walk along the junction between the top and bottom of the body, sequentially snapping the locks. A characteristic click will signal successful separation of the sections.
- 🔍 Remove the rubber legs from the bottom of the device to detect hidden screws.
- 🔓 Unscrew all screws, including those that may be under the decorative control panel.
- 🛠 Carefully divide the body, freeing the latches in a circle.
- 💧 Disconnect the water level sensor plume if it is connected to the board.
The centerpiece of the base is a round metal plate, which is an ultrasonic membrane, which is extremely sensitive to mechanical damage and contamination, and should not be scaled, because even a microscopic layer of minerals drastically reduces the efficiency of vaporization and can cause the element to overheat.
What to do if the membrane is covered with plaque?
Cleaning and maintenance of internal components
Once the insides of the device are accessed, a thorough inspection of all the units must be carried out, special attention should be paid to the duct system and the fan that pumps air through the moisturizing filter, and the accumulation of dust in this unit can lead to lower productivity and increased noise levels during operation.
Electronic control boards should be inspected with extreme caution, avoiding moisture. If you notice oxides on contacts, they can be carefully removed with alcohol or a special cleaner for electronics. Dry cleaning is a priority method of maintenance of electronic units.
| Component | Type of pollution | Cleaning method | Frequency |
|---|---|---|---|
| Ultrasonic membrane | Scale, salt. | Citric acid, soft tissue | 1 time per month |
| Water level sensor | Slime, biofilm | Washing with warm water | At every gas station. |
| Fan | Dust, pile. | Dry brush, compressed air | 1 time 3 months |
| Body of the tank | Green plaque | Disinfectant | 1 time 2 weeks |
Remember to check the condition of the sealing rings and gaskets. If the rubber has lost elasticity or is covered with cracks, it must be replaced, otherwise the system will be leaky. Regular maintenance of all seals prevents leaks and protects the countertop from water damage.
Specifics of disassembly of models Deerma and Pro versions
Deerma-branded models, which are often produced for the Xiaomi ecosystem, can have their own design features, particularly in the Deerma DEM-F600 or F620 series, the filter element and membrane are accessed through the top cover, which is fixed by a threaded connection or bayonet lock.
Pro series models are characterized by an additional silver ionizing rod or a more complex filtration system, and when disassembling such devices, it is important not to confuse the sequence of the assembly of filter elements, since a violation of the air flow can lead to improper operation of the humidity sensors.
⚠️ In models with hot steam it is strictly forbidden to touch the heating element immediately after turning off - wait for complete cooling to avoid burns.
In some versions of Xiaomi humidifiers, screws can be closed with decorative plugs, the color of which coincides with the color of the case. To find them, carefully examine the device under side lighting - the shine of the plastic plugs will differ from the matte surface of the main body. Using a hair dryer for easy heating of the plastic can make it easier to remove tightly seated plugs, but you need to warm up very carefully and short.
Assembly of the device and checking leakage
The assembly process is reversed, with the internal components being installed and the plumes connected, then the case being snapped and the screws twisted, and it's important to make sure that all the wires are packed into the channels intended for them and not clamped with plastic parts when they dock.
After assembly, but before installing the water tank, it is recommended to run a test run "dry" for a few seconds to make sure the indicators work and there are no extraneous sounds. If the device emits a strange hum or crackle, it should immediately disconnect from the network and check the correct assembly again.
- ✅ Make sure all screws are twisted evenly, without distortions.
- ✅ Check the density of the tank cover to the base.
- ✅ Make sure the rubber legs are returned to their places.
- ✅ Wipe the outer surface of the device with a dry cloth.
The final step is to test the leaks, pour a small amount of water into the tank, set it on the base, and put a dry paper napkin under the device. 10-15 minutes wipe will remain dry, so the assembly was successful and the device is ready for full operation.
💡
High-quality assembly and checking of tightness is the key to long-term operation of the humidifier and the safety of your interior from leaks.
