Title:
ANTI-SCALD WATER CUP
Document Type and Number:
WIPO Patent Application WO/2020/103843
Kind Code:
A1
Abstract:
The present invention discloses an anti-scald water cup, which comprises a cup body, an anti-scald cover is detachably fixed on the cup body, a water inlet/outlet is arranged in the middle of the anti-scald cover, the water inlet/outlet comprises a channel extending downwards from the anti-scald cover, a plugging component capable of sealing the channel is arranged below the channel, the plugging component is fixed on the bottom of the cup body through a support post made by a shape memory alloy, the phase change temperature of the shape memory alloy is a safe temperature of the water temperature, and after the phase change, the support post is elongated and can push the plugging component up to seal the channel. When the water temperature in the cup is higher than the safe temperature, the support post is elongated by the phase change, to push the plugging component up to seal the channel, so hot water cannot be poured out; when the water temperature in the cup is lower than the safe temperature, the support post retracts to its original length because of the shape memory effect, and the plugging component does not seal the channel, so water can be poured out of the channel, thereby preventing scald from pouring out too hot water by a user.
