Brief introduction of electric heating treasure principle and common fault repair _ how to exhaust electric steam and how to introduce

Electric heating hand treasure (commonly known as electric heating treasure) has novel appearance, large heat storage, long heat preservation time, reasonable structural characteristics and convenient use. It is an ideal product for warm hands and warm feet in winter. Electric heating treasure is divided into three types: electrode type, electric heating type and electric heating rod type. At present, because the electrode type electric heating treasure is prone to leakage and bursting danger, it is forbidden to be produced and sold by the state. It is allowed to continue to sell the electric heating wire type electric heating treasure with high safety.

1, can be recycled

As long as the power is about 7-10 minutes, you can keep it warm for a few hours (depending on the brand model).

2, unique heat treatment function

In winter heating, this product can be used for warm hands, warm feet, warm neck, warm body, warm quilt, etc. at lower ambient temperature; and this part of the product can eliminate fatigue, relieve back pain, abdominal pain, arthritis Pain, frozen shoulder, and sciatica have obvious relief effects.

3, beautiful appearance, fast charging

It is suitable for home life, work, and carrying out. It uses high-efficiency heat-generating agent inside, and it has high temperature and high heat preservation. It is a good gift for friends and relatives and home travel.

The working principle of the electrode type electric hot water bottle is improved on the basis of the solid electric heating cake, and the electrode type heating method is adopted, and the double temperature control insurance of the high quality temperature control and the thermal fuse is adopted. Under normal circumstances, the temperature of the liquid in the bag reaches 65 degrees, the thermostat will automatically cut off the circuit and stop heating.

This product has built-in electric heating tube (500W) and filling special liquid. It is plugged into the mains socket through the attached power cord for charging, and the power indicator light is on; when the heating temperature reaches the set flow meter (generally 75 °C) The temperature control switch contact in the normal state is automatically tripped, the power is turned off, the power indicator light is turned off, indicating that the charging has been completed, and the power cord can be removed. The entire charging process takes about 8 to 12 minutes and can effectively keep warm for 2 to 10 hours. It is suitable for children, students, the elderly and other groups of people, and also has an auxiliary physiotherapy function for some patients.

Recently, through the actual dismantling of several electric heating treasures, the internal wiring diagram is drawn to facilitate understanding of the working principle of the circuit and convenient maintenance (see the figure below).

1. No power, no heating, the indicator light does not light.

Common causes are often found in the power line disconnection, or the internal welding wire of the plug is unwelded, and the possibility of damage to the electric heating tube cannot be ruled out without heating.

2. The power is automatically turned off shortly after the power is applied.

If the inspection line connection is intact, it is suspected that the internal temperature control switch is not good. Replace the temperature switch of the same specification (75 °C). It is necessary to remind you that when the temperature control switch is replaced, the operating temperature must not exceed 100 °C. With the electric kettle temperature control switch (130 ° C), it is easy to explode when charging.

In addition, sometimes the original power cord of the electric heating treasure is lost or damaged, the new power cord re-purchased can not be used normally, should consider the different internal wiring of the plug, and the corresponding changes can be made.

1. It is to see the adhesion degree between the hot water bag filling port and the bag rubber. The joint can be turned up by hand, and there should be no cracks or debonding at the joint.

2, is to see if the hot water bottle irrigation screw has slippery teeth. If there is a slippery tooth, the hot water bottle is prone to water leakage. When selecting, choose a hot water bottle with a smooth surface and a clear thread.

3, is to see if the hot water bag feels good elasticity. The elasticity of the hot water bottle is good, indicating that the content of the rubber school for manufacturing the hot water bottle is relatively high, and the filler is relatively small. When buying, the hand can touch the hot water bottle, and the hand feel is thick, the hot water bottle is stretched and then the hand is relaxed, and the hot water bag elasticity is restored. The better.

4, is to see if the color of the hot water bottle is bright. The brightly colored hot water bottle indicates that the raw materials used in the manufacture of the hot water bottle are pure and the production process control is strict.

5, is to see if there is pollution in the hot water bottle. The hot water bottle is not in contact with human skin, and there should be no color migration on the surface of the hot water bottle. Simple discriminating method: Lightly rub the hot water bottle with absorbent cotton to see if the cotton wool is contaminated by color. The lighter the pollution, the smaller the color migration.

1. When charging electricity, do not place the hot water bottle on the fabric and heat-resistant items to avoid damage to the items during charging and heating.

2. The power supply unit must be used together. Do not use other power cords to charge the water bag of this product.

3. After the charging and heating is finished, the power should be cut off in time; if the person needs to leave for a long time during the charging process, the person should be disconnected from the power supply.

5, in order to ensure the safety of use, so as not to cause burns and accidents, do not stick to the hot water bottle when warming hands and warm quilts.

6. It is strictly forbidden to use this product under power supply.

7. After cooling the product, put it into the packing box and store it in a dry and cool place for a long time.

8, infants and young children, people with slow heat or life can not take care of themselves are strictly prohibited.

1. Do not touch with sharp objects and open flames.

2. Do not use heavy objects to press the bag.

3, the surface of the dirt can be scrubbed with a soft cloth of detergent, do not use strong solutions, such as gasoline solution, etc., so as not to damage the product.

4. Keep the socket dry before charging. It is strictly forbidden to inject sea water, brackish water, and excess tap water into the bag of electric heating treasure.

5. When charging, first insert the plug into the socket of the storage type electric heating treasure, and then turn on the power. Do not hold the electric heating treasure in your arms while charging to keep warm to prevent electric shock.

6. When charging the bag, if it is found that the bag body is obviously rising, it means that there is residual air in the bag. The power should be cut off first, then the bag body plug should be removed, and the air bag at the water injection port should be removed. The air is drained until there is water in the water inlet.

7, bagged electric heating treasure is strictly prohibited acupuncture, heavy pressure, otherwise it will cause leakage, leakage!

1. The simplest and most effective way is to shake it.

When it is heated for a few minutes, the hand warmer will bulge, and you can hear the sound of boiling water. It is actually a superficial phenomenon. The water is not very hot at all, so you can shake the electric heating treasure by hand and the gas will be scattered. go with.

2, in order to make the electric heating treasure more hot, it is necessary to repeat the above actions many times, until the hand touches the electric heating treasure is very hot, you can wait for the charging indicator to go out and cancel.

3. If your electric heating treasure has a vent, it will be easier. The venting hole is next to the power socket. There is a translucent plastic. You can use the small scissors to pry it out (approx. 8mm plastic plug) to vent or add water.

4, when the electric heating treasure is charging a little lighter on the electric heating treasure, it is best to cover the electric heating treasure, things must be controlled within 200 grams, so as to avoid danger. This also contributes to gas emissions.
