Owning Xiaomi’s ecosystem devices requires not only comfortable use, but also regular maintenance. The Antibacterial Humidifier air humidifier (often labeled JSQJS or CJJSQ) is an ultrasonic device that requires deep cleaning of mineral deposits and bacterial plaque over time. Standard tank washing is often not enough to fully disinfect internal nodes.
Users often experience a situation where the device stops giving off steam or begins to make extraneous sounds, indicating contamination of the ultrasonic membrane or failure of sensors. In this material, we will discuss in detail how to safely open the case, get to the internal components and conduct professional cleaning, maintaining the warranty and performance of the device.
It is important to understand that the design of modern Xiaomi humidifiers is designed with minimal user intervention, so all fasteners are hidden, and plastic latches require careful handling. Incorrect disassembly can damage fragile plumes or leakage, so follow the instructions consistently and without haste.
⚠️ Before any disassembly work begins, be sure to disconnect the device from the power grid and drain the water from the tank and pallet completely.
Workplace preparation and necessary tool
To successfully and safely disassemble the Xiaomi Antibacterial Humidifier, you will need a minimal set of tools that most home craftsmen will have. The main tool will be a set of screwdrivers, including cross versions of different sizes, since screws can be both standard and small, hidden under decorative elements.
It is recommended to prepare a water tank, soft lilaless wipes, cotton swabs and a cleaning product, such as citric acid or a special scale remedy. Do not use harsh chemicals, abrasive powders or hard brushes that can scratch the ultrasonic membrane or damage plastic parts. Organize the workspace so that all small parts are at hand and do not get lost in the process of work.
Pay special attention to lighting: inside the case, there are many dark corners and hidden screws that are difficult to see in dim light. A good lamp will allow you to see all the nuances of the attachment and the state of internal contacts. Before starting work, wipe the outside of the device with a dry cloth so that dirt from the case does not get inside when opening.
- 🛠️ Set of screwdrivers (cross-crosses) PH0, PH1, PH2) plough-hole.
- 🔧 Plastic blade or mediator for accurate opening of clips.
- 🧼 Cleaning solution (citric acid) and soft wipes for cleaning.
- 💡 Bright lamp for illuminating internal components and finding hidden screws.
⚠️ Warning: Never use metal tools such as a knife or screwdriver to lick the body lid.The metal easily leaves deep scratches on the plastic and can damage internal conductors or sensors.
Algorithm for removing the top cover and tank
The first step in disassembling is to dismantle the top of the device, which includes a water tank. Unlike older models where the tank was simply removed upwards, the Xiaomi Antibacterial Humidifier design can have locking elements. Remove the tank lid and flip the tank itself to access the bottom. It often has a water supply valve that needs to be gently snapped or unscrewed depending on the modification.
The main body of the humidifier, where the ultrasonic emitter is located, also requires attention. In some versions, the upper decorative grille is held on powerful latches around the perimeter. Take a plastic spatula and gently walk along the junction between the upper and lower body, sequentially snapping the locks. Movements should be confident, but without excessive effort, so as not to break the plastic "ears."
Once you remove the top panel, you'll have access to the interior space where the tank and the water supply system are located. Notice the rubber seals and gaskets: their integrity is critical to normal operation. If you notice cracks or hardening on them, these elements are better replaced, as they can cause leaks in the future.
☑️ Preparation for disassembly of the hull
When removing the tank, be careful with the float water level sensor, if it is installed in this model, which is often attached to thin guides and can easily fall out if you do not handle it carefully. Remember or photograph its position, so that when you assemble it, you can set it back correctly.
Access to the ultrasonic membrane and control board
After removing the external decorative elements and the tank, the main task is to gain access to the bottom of the device, where the ultrasonic membrane and the main control board are located. In most Xiaomi models, you need to turn the device over and twist the screws located on the bottom. These can be hidden under rubber legs or decorative stickers, so carefully examine the surface of the bottom.
Use a thin screwdriver sting to gently remove the rubber legs if the screws are underneath. Don't pull too hard to avoid tearing the rubber. Once all the screws have been unscrewed, the bottom panel should easily separate from the main body. However, don't pull sharply: sensor wires or indicators may be connected to the bottom panel that require careful shutdown.
The central element here is a metal disc, which is the ultrasonic membrane that creates the fog, which is very sensitive to mechanical stress and chemical agents, and it often forms a white coating (scalp) on its surface, which reduces the efficiency of vaporization. To clean, use soft tissue dipped in a citric acid solution, but not rub it hard.
| Component | Function | Type of pollution | Cleaning method |
|---|---|---|---|
| Ultrasonic membrane | Steam generation | Scale, salty plaque | Citric acid solution, soft tissue |
| Humidity sensor | Monitoring of moisture levels | Dust, fatty plaque | Dry cotton swab |
| Float mechanism | Dry run protection | Mucus, sediment. | Washing with warm water |
| Cooling fan | Blowing steam | Dust, wool. | Compressed air, brush |
There is often a water-free sensor next to the membrane, which is a small metal or plastic pin, and its purity is also important for the proper operation of electronics. If there is a plaque on the sensor, the device may mistakenly signal a lack of water or, conversely, work idle.
Cleaning of internal channels and ventilation systems
Inside the housing of Xiaomi's humidifier, there's a duct system and a fan that blows the vapor out. Over time, these channels can accumulate dust, down and even mold, especially if the device has been idle with water for a long time. To clean up properly, you need to remove the top of the body completely, gaining access to the internal chamber.
The fan is usually mounted on screws or plastic latches. Take it off carefully and inspect the blades: they often form a sticky layer of a mixture of water and dust, which disrupts the balance and creates noise. Wipe the blades with a wet wipe, trying not to wet the fan motor. Also check the free movement of the blades - they should rotate easily and silently.
How to clean up hard-to-reach places?
Notice the joints of plastic parts inside the enclosure. Water often accumulates in the corners and bends of the channels, which, when dried, leaves mineral traces. Wipe these places with dry cloth. If you find traces of mold (black or pink dots), treat the surfaces with a weak solution of chlorhexidine or hydrogen peroxide, but thoroughly wash the afterward product.
- 🌬️ Blow internal channels with compressed air to remove dust.
- 🧽 Wipe the fan blades with a wet napkin without pile.
- 🔍 Check for the absence of foreign objects in the air ducts.
- 🦠 Treat areas with mold disinfectant solution.
After cleaning all the internal surfaces, allow the device to dry completely before assembly, and moisture residues can short-circuit on first switching on or become a breeding ground for bacteria.
Diagnostics and maintenance of electronics
The electronic control board in Xiaomi humidifiers is usually protected from direct water intake, but condensation and high humidity can oxidize the contacts over time. When disassembling, carefully inspect the board for corrosion, swollen capacitors or signs of overheating. If you notice a greenish coating on the contacts, carefully clean them with a sweeper or soft brush moistened in alcohol.
Check the connection of the plumes and connectors. Often the problem of no steam or broken backlight is in the departed contact. Carefully disconnect and reconnect all the connectors to restore contact. Make sure that the wires are not clamped by the case and have no clamps that can lead to a chain break in the future.
⚠️ Attention! Avoid static electricity when working with electronics. Before touching the board, touch a grounded metal object or use an antistatic bracelet to avoid damaging sensitive chips with a discharge.
Pay special attention to the thermistor or temperature sensor, if it is displayed on a separate wire, its readings are critical for the antibacterial protection function. If the sensor is contaminated, it may show the wrong temperature, which will lead to malfunction of the device.
If the board shows clear signs of water ingress (corrosion, smudges), do not rush to turn on the device. Let it dry in a warm dry place for at least 24-48 hours. Turning on the wet board is guaranteed to short circuit and the electronics will fail.
Device assembly and initial start
The Xiaomi Antibacterial Humidifier is assembled in reverse order. Make sure all internal components, such as the fan and sensors, are installed in their places and securely secured. Make sure that no wires fall under the screws and are not clamped with plastic parts of the housing when connecting the halves.
When you install the top cover, make sure that all the latches fall into place with a characteristic click around the perimeter. Don't put too much effort: if the cover doesn't close, then some element is installed incorrectly or interferes with the wire.
💡
When assembly, make sure that the rubber seals on the tank and adjacent to the body lie flat and have no cracks, this will prevent water from leaking to the floor and into the electronics.
Once fully assembled, pour clean water into the tank and set it back in place. Put the device on the network. Pay attention to the indicators: if a red light is lit or the device makes intermittent sounds, check if the valve of the tank is tightly closed and there is water in the pallet. The first run after cleaning can be accompanied by a small amount of steam with a characteristic odor that will quickly disappear.
Check all modes, including night mode and fog intensity control. If the device is silent and sprays water evenly, disassembly and cleaning have been successful. Regular maintenance will extend the life of your humidifier by several years.
💡
Proper assembly and leakproofing check is a key step in ensuring the safety and long-term operation of the device after maintenance.
