The actuating element can be a flow regulator, such as a dial at the liquid outlet or a pressing member like a button for selecting different fluid flow characteristics. The actuating member can be actuated on a dispensing valve, such as a seesaw valve; wherein the actuating member can provide a contact connection and/or friction to secure the dispensing valve at a selected location to close and seal the nozzle opening One.

When the liquid dispensing device is used, the contact and/or friction of the actuating element may not provide a proper seal between the dispensing valve and the nozzle opening; further, due to high liquid pressure factors, whether by Rotating the dial provided at the liquid outlet or by pressing a button, the contact and/or friction of the actuating element used to select different fluid flow characteristics may not actuate the dispensing valve, in which case the user must Pressing or rotating the actuating element a plurality of times and/or maintaining a pressed state or maintaining a longer time. Further, the dispensing valve and the nozzle opening may not be aligned by actuation of the rotary dial, so that when the user needs to flexibly rotate the dispensing valve to align the nozzle opening, the flow is selected since the dial is rotated Features (eg, sprinkling patterns) may be inconvenient. Further, by actuation of a pressing member such as a button, it may be troublesome for the user to know the full pressing and holding time of the button. Furthermore, due to the liquid Pressure acts on the interior of the liquid dispensing device such that selecting a flow feature by pressing a button may require high forces to move the button.
