Electric kettle heating is direct heat type, with large power and small volume. Hurry up. Electric water bottle heating is also direct heating type, with small power and large volume. A little slow.

Comparison of the use of electric water bottle and electric kettle

The electric water bottle is to add water to 100 degrees. If it is only used to boil the water, use the electric water bottle. The electric water bottle is used to cook things, such as: boiling tea, boiling milk, etc. which is better, the electric water bottle or the electric water bottle? This problem needs to be selected according to your needs and application requirements. The electric kettle is better. It can be heated quickly, without waste, and can prevent repeated boiling to the greatest extent.

How to choose electric water bottle?

The primary demand depends on what kind of material you are going to choose for the thermos bottle. The thermos bottle in the market can be divided into glass vacuum thermos container and stainless steel vacuum thermos container. The former includes thermos bottle, thermos lunch box, glass liner thermos cup, and the latter is mainly stainless steel thermos cup. No matter small mouth or large mouth, portable or desk type, there are similarities in purchasing methods.

1. Simple identification method of heat preservation function

Pour boiling water into the heat preservation cup and tighten the cork or lid clockwise for 2-3 minutes, then touch the outer surface of the cup with your hand. If the cup (pot) has obvious warm phenomenon, especially the lower part of the cup is hot, it means that the vacuum degree of the product has been lost and the excellent heat preservation effect cannot be achieved, while the lower part of the heat preservation cup is always cool. Misunderstanding: some people use the ear to hear whether there is a zizzy sound to determine its heat preservation function, and the ear can't hear whether there is a vacuum.

2. Identification of sealing function

After adding water to the cup (kettle), screw the cork or lid clockwise, place the cup (kettle) flat on the table top, and there should be no water seepage; the screw in and out of the cup (kettle) lid and the cup mouth should be flexible without gap. Fill a glass of water and turn it upside down for four or five minutes, or shake it vigorously for several times to verify whether there is water leakage.

3. Simple identification method of stainless steel data

There are many specifications for stainless steel materials, among which 18 / 8 indicates that the stainless steel materials contain 18% chromium and 8% nickel. The materials meeting the specifications are green environmental protection products, which are rust proof and corrosion-resistant. Generally, the color of the stainless steel cup (pot) body is white or dark. If it is immersed in 1% salt water for 24 hours, rust spots will occur. Some of the elements contained in it are overspended, which will directly harm human health.

4. Cup appearance identification

First, check whether the outer surface of the inner tank and the outer tank are polished evenly, and whether there are bruises and scratches; second, check whether the mouth welding is smooth and common, which is related to whether the feeling of drinking water is comfortable; third, check whether the internal seal is tight, whether the plug and the cup body match; fourth, check the cup mouth, the more round the better.

5. Identification of plastic parts

Food grade new plastic features: small smell, bright appearance, no burr, long service life, not easy to aging. Characteristics of general plastics or recycled plastics: strong smell, dim color, many burrs, easy aging and simple cracking of plastics. This will not only affect the service life, but also affect the health of drinking water.

6. Simple identification of capacity

The depth of the inner tank and the height of the shell are basically the same, (the difference is 16-18mm) and the capacity is consistent with the nominal value. In order to cut corners and compensate for the missing data, some domestic brands add sand and cement blocks to the cup (pot). Myth: heavier cups are not necessarily good.

7. Check the label and other accessories of the cup

See if the product's title, capacity, caliber, manufacturer's name and address, adopted specification number, application method and precautions in application are indicated. A manufacturer who attaches great importance to quality will strictly follow the relevant national specifications and requirements to express its product functions.
