In use, user controls whether water route is got through by rotation knob (60), the muscle on knob (60)
When high step surface (41) on item (61) and control piece (40) cooperates contact, closed state until water route, as shown in figure 11.It is close at this time
The first sealing ring (91) on sealing (30) is contacted with the cooperation of groove (45) inner wall, and water flow cannot be introduced into third water hole (33),
Water flow specifically flows to are as follows: entered the water flow in water body (13) from inlet channel (11), flowed into before this from the first water hole (21), so
Enter in storage chamber (25) afterwards, then again by the second water hole (22), then through the first sluice (101), at this time by the
Under the influence of one sealing ring (91), water flow cannot be introduced into third water hole (33), to reversely flow back to storage chamber (25), reverse flow
Dynamic water flow has given sealing block (27) downward pressure, so that elastic component (23) be made to deform, second spring (52) is stretched, from
And sealing block (27) is moved downward, so that interface channel (18) are enclosed, due to the interior reverse impact sealing block of storage chamber (25)
(27) area is greater than the positive area of sealing block (27), i.e., as shown in Figure of description 11, S1 is greater than S2, therefore reverse impact
Water flow pressure be greater than forward impact water flow pressure, so that it is close so that sealing block (27) is able to achieve stablizing for interface channel (18)
Envelope.
When user wants to switch to water flowing state, knob (60) only need to be rotated, the rib being located on high step surface (41)
(61) it can be moved to along excessive face (44), radian face (43) in low step surface (42), as shown in Figure of description 10.This time control
Product (40) moves upwards under the action of the first spring (51), to make the first sealing ring (91) on sealing element (30) no
It is contacted with the inner wall of groove (45), so that water flow is made to can enter third water hole (33), the water into after third water hole (33)
Stream flows to the 4th water hole (24) on needle lid (26) again, the second sluice (82) is then flowed to, finally from water outlet (12)
Outflow.Since water flow can enter third water hole (33), to make in storage chamber (25) to be not in reflux phenomenon, in the first bullet
Under the action of spring (51), second spring (52), elastic component (23), the water flow entered in water body (13) can be easily by sealing
Block (27) ejects upwards, so that interface channel (18) are opened, to realize water flowing effect.
The preferred embodiment of the present invention has shown and described in above description, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, should not be regarded as an exclusion of other examples, and can be used for various other combinations, modification and
