| 摘要 |
The present invention is related to a battery-operated liquid dispensing device comprising a valve which is operated by the trigger ( 4 ), and which comprises a valve body ( 22 ) with a resilient dome-shaped portion ( 24 ), which closes off the valve by being biased against the valve seat ( 25 ). By pulling the trigger, the dome-shaped portion ( 24 ) is pushed away from the seat, thereby creating a passage for the liquid to pass to a gear pump ( 13 ) and nozzle ( 5 ).
