Weather thermos

It's very cold in winter, and it's chilly everywhere, especially my hands, which are stiff. In order to warm hands, many families have electric hot water bottles, which can be heated only by charging for a while. Covering your hands is very comfortable. But before use, the electric hot water bottle needs to be exhausted, so how to exhaust it? Let me share my experience with you.

1. First of all, we need to see if the electric hot water bottle is inflated because it is full of air. If it is due to other faults, the thermos bottle will be abnormal. Such problems should be carefully investigated.

2. If there is nothing wrong with it, we can put the hot water bottle flat on the table, with one side of the power interface facing up, and then find the air outlet on it. Generally, this air outlet is very small and difficult to find, and even many people don't know what it is for. In fact, it is used to put the air inside, so you need to look carefully.

3. After finding the vent, see if the small vent is easy to take out. If you can't take it out directly by hand, you need to use some tools, such as tweezers, pliers and other tools that can bite out the exhaust hole.

4. After finding the tool, bite the vent hole with the tip of tweezers or pliers and pull it back hard. If there is still no response, you can pry up the cork with a sharp weapon to expose one side and then pry it out from the other side. It should be noted that don't go straight to one side, otherwise the air outlet may not be damaged and may leak water. After both sides are taken out, you can take them off with tweezers.

5. After the vent hole is removed, it can be deflated, and the vent hole must be upward to avoid water flowing out. You can put the hot water bottle flat on the table with your palm, and slowly and forcefully press out the air inside until it becomes its original size.

Generally speaking, it is not difficult to get rid of the air in the electric hot water bottle, as long as you are patient. Of course, there are many methods. You can choose the method according to your own conditions.
