Abstract

The invention discloses a straw capable of being automatically sealed. The straw comprises a straw body, wherein a connecting part and a check ring are arranged on the inner wall of the straw body, the portion, between the connecting part and the check ring, of the straw body is a bent part, the connecting part is provided with a first water outlet, a sealing plug and a sealing piece are installed in the bent part, an elastic connecting piece is arranged on the top of the sealing piece, the upper end of the sealing plug is connected with the check ring, the lower end of the sealing plug is connected with the elastic connecting piece, and the bottom of the sealing piece is tightly attached to the connecting part. In the natural state, the sealing plug is pulled to the sealing piece by the elastic connecting piece, the straw naturally straightens, the bottom of the sealing plug makes close contact with the sealing piece so that the sealing effect can be formed, liquid in a bottle can be effectively prevented from being poured out, and air, impurities and the like can be effectively prevented from entering the bottle; in the drinking process, the straw is pulled, the bent part elastically deforms, the bottom of the sealing plug is separated from the sealing piece, liquid in the bottle can flow out, the straw is convenient to use, and the straw has the sealing function and the anti-leakage function.
