When the impeller 200 rotates, the first and second driving parts 230 and 240 selectively drive the first and second blades 300 and 400 to move in opposite directions along the axis of the impeller 200, wherein the movement in opposite directions means that the first and second blades 300 and 400 move in opposite directions, for example: when the first blade 300 moves toward the direction approaching the face cover 120, the second blade 400 moves toward the direction away from the face cover 120; when the first blade 300 moves in a direction away from the face cover 120, the second blade 400 moves in a direction close to the face cover 120.
Referring to fig. 2, 5 and 6 together, in some embodiments, the first blade 300 is substantially semicircular, the second blade 400 is substantially semicircular, and the first blade 300 and the second blade 400 can be spliced to form a substantially circular shape, the first blade 300 is provided with a first locking groove 320 for engaging with the first mounting shaft 500, the second blade 400 is provided with a second locking groove 420 for engaging with the mounting shaft 500, and the mounting shaft 500 is inserted into the first locking groove 320 and the second locking groove 420 to form an assembly, it can be understood that in the present embodiment, the first blade 300 and the mounting shaft 500 are in clearance fit, that is, the first blade 300 and the mounting shaft 500 are not connected, and similarly, the second blade 400 and the mounting shaft 500 are also in clearance fit, that is, the second blade 400 and the mounting shaft 500 are not connected.
In this embodiment, a side of the first blade 300 facing the second driving portion 240 is provided with a third inclined surface 310 engaged with the second inclined surface 241, wherein during the rotation of the impeller 200, the third inclined surface 310 can completely engage with the second inclined surface 241, and when the third inclined surface 310 just begins to engage with the second inclined surface 241, the second driving portion 240 applies a force to the third inclined surface 310 in a direction away from the face cover 120, so that the first blade 300 tilts in a direction away from the face cover 120, and when the third inclined surface 310 disengages from the second inclined surface 241, the first blade 300 can return to the initial position under the driving of its own gravity.
A fourth inclined plane 410 matched with the second inclined plane 241 is arranged on one side of the second blade 400 facing the second driving portion 240, when the fourth inclined plane 410 is just attached to the second inclined plane 241, the second driving portion 240 applies a force to the fourth inclined plane 410 in a direction away from the face cover 120, so that the second blade 400 is tilted in a direction away from the face cover 120, and when the fourth inclined plane 410 is separated from the second inclined plane 241, the second blade 400 can return to an initial position under the driving of self gravity. When the second driving portion 240 contacts the first blade 300, it does not contact the second blade 400, and when the second driving portion 240 contacts the second blade 400, it does not contact the first blade 300.
Referring to fig. 6, the first blade 300 further defines a first yielding slot 330 engaged with the first driving portion 230, the first yielding slot 330 is adjacent to the second blade 400, that is, the first yielding slot 330 is located near the second blade 400. The second blade 400 is provided with a second abdicating groove 430 matched with the first driving part 230, the second abdicating groove 430 is adjacent to the first blade 300, that is, the second abdicating groove 430 is located at a position close to the first blade 300.
Taking the second relief groove 430 as an example, when the impeller 200 rotates, the first inclined surface 231 of the first driving portion 230 starts to contact with the first blade 300, a force is applied to the first blade 300 in a direction toward the face cover 120, so that the first blade 300 moves in the direction toward the face cover 120, at this time, the second driving portion 240 contacts with the second blade 400 and drives the second blade 400 to move in a direction away from the face cover 120, when the first driving portion 230 rotates to gradually separate from the first blade 300, the second driving portion 240 rotates to gradually separate from the second blade 400, and the second blade 400 is in a state of being tilted with respect to the first blade 300 and the face cover 120. At this time, the first driving portion 230 is clamped by the second blade 400, and by providing the second receding slot 430, the first driving portion 230 enters the second receding slot 430 first when switching to the second blade 400, and as the second blade 400 is separated from the second driving portion 240, the second blade 400 returns to the initial state, and at this time, the first driving portion 230 can gradually apply a force to the second blade 400 toward the face cover 120, so as to form a periodic motion.
Referring to fig. 1 again, in some embodiments, the water outlet device 10 may further include a first elastic element 710 and a second elastic element 720, two ends of the first elastic element 710 respectively abut against the main body 110 and the first blade 300, two ends of the second elastic element 720 respectively abut against the main body 110 and the second blade 400, and the first elastic element 710 and the second elastic element 720 mainly act to exert an active restoring force on the first blade 300 and the second blade 400. Specifically, after the first blade 300 and the second blade 400 tilt under the action of the second driving portion 240, the first elastic member 710 and the second elastic member 720 are respectively pressed, and when the second driving portion 240 is separated from the first blade 300, the first elastic member 710 recovers to deform to apply a force to the first blade 300 in a direction toward the face cover 120, so that the first blade 300 can rapidly recover to the initial position.
It should be understood that the initial position mentioned above in this application only represents the position of the first blade 300 and the second blade 400 when the water outlet device 10 is not flowing water, and the first blade 300 is located in the first region 121 and the second blade 400 is located in the second region 122.
The working principle of the water outlet device 10 provided by the invention is as follows:
referring to fig. 2, the water outlet apparatus 10 in fig. 2 is in a water non-passing state, when the water outlet apparatus 10 is not passing water, the first blade 300 and the second blade 400 are both located at initial positions, where the initial positions refer to that the first blade 300 and the second blade 400 are respectively located in the first area 121 and the second area 122, and cover the water outlet hole 124 of the first area 121 and the water outlet hole 124 of the second area 122.
Referring to fig. 7, after the water outlet device 10 is filled with water, the water flow impacts the impeller 200 and drives the impeller 200 to rotate, at this time, the first driving portion 230 and the second driving portion 240 rotate along with the impeller, and when the first driving portion 230 rotates to contact with the first blade 300, the second driving portion 240 rotates to contact with the second blade 400. At this time, the first blade 300 is pressed into the first area 121 by the force of the first driving part 230 in the direction toward the face cover 120, and the water outlet hole 124 located in the first area 121 is covered by the first blade 300, so that the water flow cannot flow out of the first area 121; when the second blade 400 is subjected to a force of the second driving portion 240 in a direction away from the face cover 120, the second blade 400 tilts, the water outlet 124 located in the second region 122 leaks, and water flows through a gap between the impeller 200 and the second blade 400, enters the second region 122, and flows out of the water outlet 124 in the second region 122.
Referring to fig. 8, when the impeller 200 continues to rotate until the first driving portion 230 moves to contact the second blade 400 and the second region 122 moves to contact the first blade 300. At this time, the second blade 400 is pressed into the second region 122 by the force of the first driving part 230 in the direction toward the face cover 120, and the water outlet hole 124 located in the second region 122 is covered by the second blade 400, so that the water flow cannot flow out of the second region 122; when the first blade 300 is forced by the second driving part 240 in a direction away from the face cover 120, the first blade 300 tilts, and the water outlet 124 in the first area 121 leaks, so that water flows through the gap between the impeller 200 and the first blade 300, enters the first area 121, and flows out of the water outlet 124 in the first area 121.
The water flow periodically flows out of the first area 121 or the second area 122 in such a reciprocating manner, and due to the periodic change of the water outlet position, when a user uses the water outlet device, the water flow of the water outlet device 10 periodically changes to hit different positions of the skin of the human body, so that a massage effect is achieved.
The above operation principle is only for convenience of understanding, and it should be noted that, since the water outlet device 10 periodically discharges water from the first area 121 or the second area 122 when operating, the above operation principle is not used to limit the water discharging sequence of the water outlet device 10 when in use.
It should be noted that, in some other embodiments, the water outlet device 10 may further include a third blade or more blades, and a third driving portion or more driving portions may be disposed on the corresponding impeller 200. Only a plurality of driving parts of the third blade are required to be matched with one blade in the rotating process.
The water outlet device 10 may be applied to a shower head, or other spray head. As an example, referring to fig. 9, the embodiment further provides a shower head 20, which may include a handle 600 and the above-mentioned water outlet device 10, wherein the structure and the operation principle of the water outlet device 10 may refer to the above contents.
