Scald preventing sucker

The invention relates to a scald preventing sucker which comprises a sucker body, wherein a layer of materials changing colors along with temperature is coated at the outer layer of the front end of the sucker body or the middle of the sucker is provided with a layer of high-temperature shrinking materials. In the first scheme, when the temperature is overhigh, the materials changing colors along with the increase of the temperature can generate color change after the front end of the sucker body is inserted into beverage. In second scheme, even if the beverage is sucked into a mouth, the flow of the beverage can be greatly reduced, and accidental injuries, such as scalding, and the like can not be brought to a drinker because the materials are shrunk along with the increase of the temperature.
