Bidirectional self-sealing drinking water suction nozzle device

The invention relates to a bidirectional self-sealing drinking water suction nozzle device, in particular to a drinking water suction nozzle device which has a self-sealing function and can be unlocked and sealed without manual operation, and belongs to the field of drinking water devices. The invention provides a miniature drinking water suction nozzle device which has a self-sealing function anddoes not need to be operated by hands. When no water is being drunk, a pipeline is automatically sealed. Drinking water leakage caused by body extrusion, violent shaking, environmental air pressure change and the like and drinking water pollution caused by harsh environments can be prevented. When in use, unlocking and water drinking are realized only by slightly biting the suction nozzle with teeth, and the device is automatically sealed after water drinking is finished.
