Abstract

The disclosure provides an anti-pollution bottle cap comprising a cap body, a liquid drainage one-way valve and an air intake one-way valve. A liquid drainage hole and an air intake hole are disposed in the cap body and both communicated with an inside of the cap body. The liquid drainage one-way valve is disposed in a space enclosed by the cap body. The liquid drainage hole is blocked by the liquid drainage one-way valve in one way so as to be opened during toppling operation. The air intake one-way valve is disposed in the space enclosed by the cap body. The air intake hole is blocked by the air intake one-way valve in one way so as to be closed during toppling operation. In application, the anti-pollution bottle cap will be installed on a bottle for matched use, so that a user can normally drain liquid through the liquid drainage hole only by squeezing the bottle. When use is stopped, through blockage of the liquid drainage one-way valve to the liquid drainage hole, adherends on the body surface of the user are prevented from entering the bottle, contents will not be polluted, and the problem that an existing bottle cap is likely to pollute contents is practically solved.
