Xiaomi's corkscrew is not just a kitchen accessory, it's a smart device that combines stylish design, durable metal and innovative mechanism. But even the most reliable technology can fail: jams the thread, breaks the handle or stops opening automatically, in which cases, disassembling the corkscrew becomes necessary — whether for cleaning, lubricating or replacing parts.
In this article, you will find step-by-step instructions for disassembling the Xiaomi corkscrew, taking into account the features of different models (for example, the Mijia Electric Corkscrew or the Xiaomi Smartmi Corkscrew), we will tell you what tools you will need, how to avoid damage to the mechanism and what to do if the corkscrew does not understand “from the book”, and also we will analyze typical breakdowns and ways to fix them without going to the service center.
Warning: Disassembly may cancel warranty if the device is still in warranty service, but if you're willing to take a risk, go ahead!
What Xiaomi corkscrew models can be disassembled independently
Not all of Xiaomi’s corkscrews are disassemblable at home, and here’s a list of models you can handle without special equipment:
- 🔧 Mijia Electric Corkscrew (LYWSD01FM) — electric model with lithium-ion battery, disassembled to replace the battery or clean the gears.
- 🔧 Xiaomi Smartmi Automatic Corkscrew (ZNMSJ01FM) — automatic corkscrew with push-button control, requires disassembly when jamming the mechanism.
- 🔧 Xiaomi Youpin Manual Corkscrew (metal, no electronics) - mechanical model, disassembled for lubrication or replacement of the spiral.
But the Xiaomi Mi Smart Corkscrew Pro (if it comes in the future) may have a non-shattered case or special latches that are difficult to open without damage. Always check user reviews on forums before disassembling - perhaps someone has already encountered your problem.
If your model is not on the list, it doesn't mean it can't be disassembled, it just might require more effort or custom tools, like some corkscrews being glued together and having to be carefully warmed up with a hairdryer.
Preparation for disassembly: tools and security measures
Before you start the screwdriver, prepare everything you need. Here is the minimum toolkit that most models will need:
- 🔨 Flat and cross screwdriver (size depends on screws - usually T5 or T6 Xiaomi).
- 🔧 Plastic blades (for disengagement of the body without scratches).
- 🧲 Magnetic mat or container (to avoid losing small details).
- 🔥 Hair dryer or heat gun (if the body is glued together).
- 🧴 Lubrication for machinery (e.g, WD-40 silicone-grease).
- 📸 Smartphone for photography (to capture the location of details).
Also prepare an alcohol wipe to clean the contacts (if you disassemble the electric model) and a multimeter to check the voltage on the battery.
⚠️ Note: If your Xiaomi corkscrew has a battery, don’t disassemble it immediately after use – let the battery cool for 10-15 minutes to avoid short circuits. Also don’t use metal tools to disconnect plastic latches – they break easily!
Work on a clean, well-lit surface. If you disassemble an electrical model, disconnect it from charging and make sure the power button is not pressed (some corkscrews may accidentally activate when you manipulate the mechanism).
Step-by-step: how to disassemble the corkscrew Xiaomi
Consider a universal disassembly algorithm, using the Mijia Electric Corkscrew, where the steps may vary slightly for other models, but the overall logic is maintained.
Step 1: Removal of the upper cover
On most Xiaomi corkscrews, the top of the body is mounted on latches or screws. Carefully swipe the plastic blade along the seam between the top and bottom, starting from where there are no buttons or connectors. If the lid does not lend itself, perhaps the body is glued together - then warm up the seam with a hair dryer (temperature not higher than 60).°C to avoid damaging the plastic).
In models with screws (like the Smartmi Automatic Corkscrew), unscrew them first.The screws can be hidden under stickers or rubber legs - check carefully!
Step 2: Removal of the battery (for electric models)
If your corkscrew is battery-operated, you'll see the battery when you take the lid off, usually attached to the connector or soldered to the board. Don't pull the wires! Carefully disconnect the connector or unfurl the contacts if they're soldered (you'll need a soldering iron).
Check the battery voltage with a multimeter if it's lower. 3.0V, Mijia models often use a battery of the type 18650, which can be bought separately.
Step 3: Disassembly of the mechanical part
The mechanism of the corkscrew usually consists of:
- 🌀 Spirals (stack) - metal rod with thread.
- ⚙️ gear - transmit rotation from the motor (in electric models) or from the handle (in mechanical models).
- 🔄 Springs and fixtures – provide automatic return of the spiral.
Take a picture of the parts before extraction! The gears often fall out of the grooves, and without a photo it will be difficult to put everything back together. Use an alcohol wipe to clean the mechanism, and for lubrication use silicone lubricant (do not overdo it so that dust does not collect).

Step 4: Diagnostics and troubleshooting
Now that the corkscrew is disassembled, inspect the details for damage:
- 🔍 Spiral bent or blunted → straighten with pliers or replace.
- ⚙️ The gears are chipped or worn out → Replacement is required (parts can be found on AliExpress).
- 🔋 The battery is swelling. → Dispose of it immediately!Using a bloated battery is dangerous.
- 💧 There's a liquid in the machine. → Dry the parts with a hair dryer and lubricate again.
If the corkscrew does not turn on, check the fee for the presence of burned elements or cold soldering. In most cases, repairing the board at home is impossible - it is easier to buy a new corkscrew.
Typical problems and their solutions
Here are the most common Xiaomi corkscrew breaks and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The corkscrew doesn't rotate. | Jammed gears, contamination of the machine | Disassemble, clean and lubricate the gears |
| The battery does not hold the charge. | Battery wear (more than 500 charging cycles) | Replace the battery with a new one (type 18650) |
| Spiral's not fixed in traffic. | Wear of the thread on the spiral | Replace the spiral or slash the thread with a file |
| The corkscrew spontaneously turns on | Closing of a button or a board malfunction | Check the button with a multimeter, if necessary, replace it |
| The hull cracked. | Excessive force or impact when opening | Glue epoxy glue or replace the body |
If the problem remains after dismantling and cleaning, the electronics may have malfunctioned, in which case contact Xiaomi service center or consider buying a new corkscrew - repairing the board can cost more.
⚠️ Note: If your Xiaomi corkscrew is equipped with a backlight function (for example, Smartmi Corkscrew with) LED), Be careful with LEDs - they easily overheat when soldering. It is better to replace the entire board with diodes if they fail.
What to do if the corkscrew is not understood
Sometimes the corkscrew body is indissoluble, either glued together or attached to special latches that break when you try to open.
- 🔥 Warm up the body with a hair dryer (temperature 60-70)°C) at the seam, then try to separate with a plastic blade.
- 🔪 Carefully cut the seam with a stationery knife (only if you are ready for the fact that the body will be damaged).
- 🛠️ Contact the workshop - some services have special equipment for opening glued cases.
- 💰 Buy a new corkscrew – if the device is old or cheap, repairs may not be cost-effective.
If you do decide to force the body open, remember that the warranty will be lost and the appearance of the device may suffer.

Conversion of the corkscrew after disassembly
Collecting the corkscrew back is often more difficult than disassembling. Follow these tips to avoid mistakes:
- Check all the sealing rings (if any) - they need to be installed in place, otherwise the mechanism will backfire.
- Lubricate the gears and the coil with a thin layer of silicone lubricant. Don't use oil-based oils, they can damage the plastic.
- Make sure the battery is connected correctly – the reverse polarity can knock the board out.
- Twisting the screws cross-cross to avoid skewing the body.
- Check the operation of the corkscrew before the final assembly - connect the battery and test the mechanism without the lid.
If after assembly the corkscrew works incorrectly (for example, the spiral rotates in jerks), disassemble it again and check:
- 🔄 Correct installation of gears (they should be tightly coupled).
- 🧲 Presence of foreign objects in the mechanism (for example, plastic debris).
- 🔌 Quality of battery contacts (sometimes oxidized contacts cause failures).
If you're doing it right, but the corkscrew doesn't work, you might have damaged the board or the motor when you disassemble it, and you're going to need a specialist.
💡
The most common mistake in assembly is to install the springs incorrectly, and if the spiral does not return to its original position, check if the spring is twisted or if the lock has fallen out.
Where to buy spare parts for the corkscrew Xiaomi
If you find that you need to replace the parts, here’s where you can find them:
- 🛒 AliExpress is the largest selection of Xiaomi parts, including gears, spirals and batteries).
- 🏬 Xiaomi’s official service centers – can sell original parts, but prices are usually higher.
- 🔧 Radio parts stores - here you can buy universal gears, springs or batteries 18650.
- 📦 Doogee, Gearbest, Banggood – alternative sites with spare parts for smart equipment.
When buying spare parts, pay attention to:
- 📏 Dimensions - gears and spirals should fit exactly in diameter.
- 🔋 Battery characteristics – voltage and capacity must match the original.
- 📄 Customer reviews – often indicate whether a part fits a particular model.
If you are not sure about your choice, order a part from a seller with a good rating and return option. For example, on AliExpress, many stores offer a free refund within 15 days.
