**What is an Electric Heating Treasure?**
An electric heating treasure, commonly referred to as an electric heating pad or hand warmer, is a modern and innovative product designed for warmth during cold seasons. It features a unique design, large heat storage capacity, long-lasting warmth, and a well-structured layout that makes it user-friendly. This device is ideal for warming hands, feet, and even the body in winter. There are three main types of electric heating treasures: electrode type, electric heating type, and electric heating rod type. However, due to safety concerns, the electrode type has been banned from production and sale by the government. Only the electric heating wire type is currently allowed on the market because of its higher safety standards.
**Key Features of Electric Heating Treasure**
1. **Energy Efficient and Long Lasting**
With just 7–10 minutes of charging, it can keep you warm for several hours, depending on the model and brand.
2. **Multi-Purpose Heat Therapy**
It can be used for warming hands, feet, neck, back, and even a bed. It also helps relieve fatigue, back pain, stomach cramps, arthritis, frozen shoulder, and sciatica.
3. **Stylish Design and Fast Charging**
Its attractive appearance and quick heating make it suitable for home use, office settings, and travel. The high-efficiency heat-generating agent inside ensures rapid heating and excellent thermal retention, making it a great gift for family and friends.
**How Does an Electric Heating Treasure Work?**
The working principle of the electrode-type electric heating bag is based on solid-state electric heating technology. It uses a double temperature control system with a thermostat and a thermal fuse. When the internal liquid reaches about 65°C, the thermostat automatically cuts off the power to prevent overheating. This ensures safe and efficient operation.
**Common Faults and Repairs**
Most electric heating treasures come with a built-in electric heating tube (typically 500W) and a special filling liquid. When plugged into the power source, the indicator light turns on, and after about 8–12 minutes of charging, the temperature reaches 75°C, triggering the temperature switch to cut off the power. The unit can maintain warmth for up to 10 hours. If issues arise, such as no power or automatic shutdown, check the wiring, plug connections, or replace the temperature control switch if necessary. Always ensure that the replacement switch is of the correct temperature rating to avoid potential hazards.
**Tips for Buying an Electric Heating Treasure**
1. Check the connection between the filling port and the rubber bag for firmness and integrity.
2. Ensure the screw threads on the cap are smooth and not worn out.
3. Test the elasticity of the bag by pressing and releasing; a good one should return to its original shape quickly.
4. Look for bright and consistent color, which indicates high-quality materials.
5. Inspect the surface for any color transfer or contamination, which may indicate poor quality.
**Usage Precautions**
1. Avoid placing the heating treasure on fabric or heat-sensitive items while charging.
2. Use only the original power cord provided with the product.
3. Turn off the power after use and unplug when not in use for extended periods.
4. Do not leave it unattended while charging.
5. Never touch the device directly while it's hot to avoid burns.
6. Do not use it while it's connected to the power supply.
7. Store it in a dry and cool place after cooling down.
8. Not recommended for infants, elderly, or individuals who cannot manage it independently.
**Maintenance and Care**
1. Avoid contact with sharp objects or open flames.
2. Do not press heavy objects onto the bag.
3. Clean the surface with a soft cloth and mild detergent. Avoid using harsh chemicals.
4. Keep the socket dry before charging. Do not fill with seawater or excess tap water.
5. Always plug in first before turning on the power.
6. If the bag swells during charging, turn it off and release the air.
7. Never puncture or apply heavy pressure, as this could cause leaks.
**How to Release Steam and Improve Performance**
1. Shake the device gently to disperse any trapped air. This helps distribute heat evenly.
2. Repeat the shaking process multiple times until the device feels consistently warm.
3. If there is a vent hole near the power plug, you can carefully remove the small plastic cover to release steam or add water.
4. Cover the device with a light object (no more than 200g) during charging to help release gas and improve performance.
Electric heating treasures are a convenient and practical solution for staying warm during the winter months. By following the proper usage and maintenance guidelines, you can ensure both safety and longevity of the product.
