Water bottle having ventilation and pressure relief function

Abstract

A water bottle (100) having a ventilation and pressure relief function, comprising a bottle body (10) and a bottle cover (20) mounted at the upper end of the bottle body (10), wherein a vent hole (21) and a water through hole (22) which are communicated with the interior of the bottle body (10) are formed in the bottle cover (20); the water bottle (100) further comprises a water drinking tube (30), and the water drinking tube (30) is movably arranged on the bottle cover (20); when the water drinking tube (30) is at a first position, the vent hole (21) and the water through hole (22) are in a sealed state; when the water drinking tube (30) moves from the first position to a second position, the vent hole (21) is in an open state; when the water drinking tube (30) moves from the second position to a third position, the water drinking tube (30) is communicated with the water through hole (22). When a user needs to drink water, the user can first move the water drinking tube (30) from the first position to the second position to open the vent hole (21) for pressure relief and ventilation, and then move the water drinking tube (30) from the second position to the third position so that the water drinking tube (30) is communicated with the water through hole (22). In this way, accidental injuries to users due to spouting of hot water can be avoided, and a user can move the water drinking tube (30) to the first position at any time, so that the vent hole (21) and the water through hole (22) are sealed at the same time, thereby avoiding water leakage and facilitating carrying by the user.
