The position of the water receiving member 21 is the upper side, and the position of the base 23 is the lower side.

Referring to fig. 4 and 5, in the present embodiment, the main body of the water receiving member 21 is a plate-shaped member, a groove-shaped structure with a circular cross section is formed by recessing inwards at a middle position of a lower side surface of the plate-shaped member, a through hole is provided at a center position of the groove-shaped structure, the through hole forms a water inlet hole 212, a screw stud is provided at an upper side surface of the plate-shaped member corresponding to the position of the water inlet hole 212, the screw stud is provided with an external thread, and the inside of the screw stud is hollow and communicated with the through hole. The water receiving member 21 may be fixedly connected to an external water inlet pipe member through a screw post, thereby introducing water into the water outlet device.

Referring to fig. 4 and 5, in the present embodiment, the main body portion of the upper cover 22 is also a plate-shaped member, a first cylindrical structure with a circular cross section and a hollow interior is formed by downwardly protruding from the lower side surface of the plate-shaped member, an internal thread is provided on the inner wall of the first cylindrical structure, and an upper cover water passing hole 221 is provided at the bottom wall (upper end of the first cylindrical structure) of the first cylindrical structure; the upper side surface of the plate-shaped component protrudes upwards to form another second cylindrical structure with a circular cross section and a hollow inner part, the outer diameter of the second cylindrical structure is equal to the inner diameter of the side wall of the groove-shaped structure of the water receiving piece 21 on the lower side of the second cylindrical structure, and the outer wall of the second cylindrical structure is sleeved with a first sealing ring 31. The second cylindrical structure of the upper cover 22 can be inserted into the groove-shaped structure of the water receiving member 21 and forms a water inlet cavity 211 by matching with the groove-shaped structure, the first sealing ring 31 can prevent the water inlet cavity 211 from leaking, and the upper cover 22 can be stably fixedly connected with the water receiving member 21 in a bonding, clamping or welding mode.

Referring to fig. 2, 4 and 5, the base 23 is a cylindrical member having a bottom wall, a cavity is formed inside the cylindrical member, the outer diameter of the cylindrical member is matched with the inner diameter of the first cylindrical structure formed on the lower surface of the upper cover 22, and the outer wall of the cylindrical member is provided with an external thread matched with the upper cover 22, so that the base 23 can be screwed on the upper cover 22 and matched with the upper cover 22 to form the base of the water outlet device, and the upper opening of the base 23 is blocked by the lower surface of the upper cover 22, so as to form a closed cavity, i.e., the water passing cavity 235. A circle of protruding ribs 238 are circumferentially arranged on the outer wall of the base 23 near the upper opening, when the base 23 is fixedly connected with the upper cover 22, the inner wall of the first columnar structure and the outer wall of the base 23 are matched with the protruding ribs to form a water inlet groove 239, and the outlet of the water through hole 221 of the upper cover is exactly corresponding to the water inlet groove 239. The water inlet groove 239, the upper cover water through hole 221 and the water inlet cavity 211 jointly form a water inlet channel of the base. A second sealing ring 32 and a third sealing ring 33 are respectively arranged at the upper end surface of the base 23 and the middle position of the outer wall of the base, and the two sealing rings can prevent water in the water inlet groove 239 from being leaked.

The side wall of the base 23 is also provided with a plurality of inclined water holes 236 running through the side wall along the circumferential direction, the inclined water holes 236 form a first inclined water channel of the base, and the inlet of the first inclined water channel corresponds to the position of the water inlet groove on the outer wall of the base 23. Referring to fig. 4, the slanted direction of the slanted water holes 236 causes the water flow to enter the water passing chamber 235 from the outlets of the slanted water holes 236 in a clockwise direction.

A second water outlet hole 234 penetrating through the bottom wall of the base 23 is formed in the center of the bottom wall of the base 23, a circle of bosses 232 are arranged at positions, close to the second water outlet hole 234, of the bottom wall, the bosses 232 are of annular structures protruding out of the bottom wall and surround an opening, facing the water passing cavity 235, of the second water outlet hole 234, and the bosses 232 penetrate through the second water outlet hole 234; and the inner wall of the boss 232 is connected with the inner wall of the second outlet hole 234. The inclined water groove 233 is provided on the boss 232, the inclined water groove 233 forms a second inclined water passage on the base, and the extending direction of the inclined water groove 233 is perpendicular to the protruding direction of the boss 232, and penetrates the inner wall and the outer wall of the boss 232, and it forms an opening on the upper end face of the boss 232. Referring to fig. 5, the oblique water tank 233 communicates with the water passing chamber 235 and the second outlet hole 234, and is inclined in such a direction that water flows from the outlet of the oblique water tank 233 into the second outlet hole 234 in a counterclockwise direction.

In addition, a protruding rib 231 higher than the upper end surface of the boss 232 is formed at the outer wall of the boss 232 and protrudes toward the water passing cavity 235, and the inclined water tank 233 also penetrates through the protruding rib 231. The protruding ribs 231 are engaged with the upper end surface of the boss 232 to form a step-shaped structure, and engaged with the second outlet hole 234 to form a step-shaped hole structure.

Referring to fig. 3, the main portion of the rotor 10 is a cylindrical member, a plurality of vanes 11 extending in the radial direction of the rotor 10 are circumferentially arranged at an upper position of the rotor 10, the position of the vanes 11 is a first position on the rotor 10, when the rotor 10 is installed in the water passing chamber 235, the extension direction of the inclined water holes 236 is perpendicular to the axial direction of the rotor 10, and water flow guided by the inclined water holes 236 impinges on the vanes 11, thereby driving the rotor 10 to rotate in the first direction. In this embodiment, the first direction is a clockwise direction.

A circumferentially extending flange 12 projects radially outwardly at a central location of the rotor 10. The outer wall surface of the rotor 10 at a position below the flange 12 forms a rotating surface 14, and the rotating surface 14 is a second position on the rotor 10. A plurality of water passing grooves 13 are circumferentially arranged on the rotating surface 14, the water passing grooves 13 axially extend along the rotating member 10, and both ends of the water passing grooves are closed.

A first water outlet channel 16 is further arranged in the rotating piece 10 along the axial direction thereof, the upper end of the first water outlet channel 16 is communicated to the upper end surface of the rotating piece 10, and when the rotating piece 10 is arranged in the water passing cavity 235, the first water outlet channel 16 can be communicated with the water passing cavity 235; the lower end of the first water outlet channel 16 forms a first water outlet channel outlet 15, which can discharge the water in the water passing chamber 235 to the outside of the water outlet device. Meanwhile, in the present embodiment, the first water outlet channel outlet 15 is in a spindle shape, which can form a blade-shaped water outlet.

The outer diameter of the rotating surface 14 of the rotating member 10 is slightly smaller than the inner diameter of the second water outlet hole 234, so that the lower end of the rotating member 10 can be inserted into the second water outlet hole 234, and the outer diameter of the flange 12 is substantially equal to the inner diameter of the protruding rib 231, so that the rotating member 10 can be lapped on the upper end surface of the boss 232 and limited by the protruding rib 231, thereby preventing the rotating member 10 from shifting, and simultaneously, a water gap is formed between the rotating surface 14 and the inner wall of the second water outlet hole 234, and the water gap forms a second water outlet channel; when the flange 12 is overlapped on the boss 232, the flange 12 can also cover the upward opening of the inclined water groove 233 on the boss 232, so that the water flow in the water passing chamber 235 can only enter the inclined water groove 233 from the outside of the protruding rib 231.

When the rotating member 10 is overlapped on the boss 232, the position of the water passing groove 13 just corresponds to the outlet of the inclined water groove 233, the extending direction of the inclined water groove 233 is also vertical to the axial direction of the rotating member 10, and the water flow guided by the inclined water groove 233 impacts on the side wall of the water passing groove 13 and exerts a pushing force on the rotating member 10. In this embodiment, the driving force applied by the water flow guided by the inclined water trough 233 is the rotation resistance of the rotation member 10, and the direction of the force applied by the water flow guided by the inclined water holes 236 is opposite to the driving force applied by the water flow guided by the inclined water holes 233 to the rotation member 10, but since the water passing cavity 235 is directly communicated with the first water outlet channel 16 and the water passing area of the first water outlet channel 15 is far larger than that of the second water outlet channel, the driving force applied by the water flow guided by the inclined water holes 236 is also larger than the resistance applied by the water flow guided by the inclined water trough 233, the rotation member 10 still rotates along the first direction, but since it receives the rotation resistance at the same time, the rotation speed is reduced, so as to achieve the purpose of decelerating the rotation member 10, and at this time, the water shape of the blade water formed by the rotation member 10 is softer.

In addition, although the inclined water groove 233 and the inclined water hole 236 are provided in the embodiment such that the extending directions thereof are perpendicular to the axial direction of the rotation member 10, the extending directions thereof may be inclined to the axial direction of the rotation member 10 as long as the water flow guided therethrough can exert the urging force to rotate the rotation member 10, and the perpendicular direction is a preferred embodiment.

Referring to fig. 6, the water exiting from the second water outlet channel forms a water curtain outside the blade-shaped water exiting from the first water outlet channel 15, and the water curtain can prevent the blade water from splashing.

During assembly, the rotating member 10 is mounted on the base 23, the base 23 is screwed to the upper cover 22, and then the upper cover 22 is fixedly connected with the water receiving member 21, so that the water outlet device shown in fig. 7 is finally obtained.

Example two

The difference between the second embodiment and the first embodiment is that the base 23 and the rotating member 10 have different structures.

Referring to fig. 8, in the present embodiment, compared with the base 23 in the first embodiment, the differences are: the bottom wall of the base 23 is provided with a second water outlet hole 234 which is the same as that in the first embodiment, a boss 232 is arranged at a position corresponding to the second water outlet hole 234, and the boss 232 is provided with an inclined water tank 233 which is the same as that in the first embodiment; meanwhile, a plurality of first water outlet holes 237 are circumferentially arranged on the bottom wall of the base 23, and the first water outlet holes 237 are located between the bosses 232 and the side wall of the base 23.

Referring to fig. 9, in the present embodiment, compared with the rotor 10 in the first embodiment, the differences are: three water baffles 17 are further arranged on the outer edge of the flange 12 of the rotating member 10, the lower side surface of each water baffle 17 is lower than the lower side surface of the flange 12, so that a lapping groove 171 is formed between the rotating surface 14 and the water baffles 17, the width of the lapping groove 171 is equal to that of the boss 232, when the rotating member 10 is inserted into the second water outlet 234, the lapping groove 171 can be matched with the boss 232 in an inserted mode, the rotating member 10 is prevented from shifting, and the flange 12 is lapped on the boss 232. Meanwhile, the bottom end of the first water outlet channel 16 on the rotating member 10 is closed, and water can only flow out from the first water outlet hole 237 and the gap between the rotating member 10 and the second water outlet hole 234.

When the rotating member 10 rotates, the water baffle 17 intermittently blocks the first water outlet 237, so that the water outlet device forms an intermittent massage water pattern.

EXAMPLE III

The third embodiment is different from the second embodiment in that the base 23 and the rotating member 10 have different structures.

Referring to fig. 10, in the present embodiment, compared with the base 23 in the second embodiment, the differences are: the downwardly facing opening of the second outlet aperture 234 in the bottom wall of the base 23 is closed to form a counter bore.

Referring to fig. 11, in the present embodiment, compared with the rotating member 10 of the second embodiment, a difference is that the rotating member 10 forms a water returning cavity 18 corresponding to the original structure of the first water outlet channel 16, and when the rotating member 10 is installed in the water passing cavity 235, the upper end of the water returning cavity 18 is communicated with the water passing cavity 235. A water return chamber passing hole 181 is provided on the rotation surface 14 of the rotation member 10, and the water return chamber passing hole 181 has a structure similar to that of the water passing groove 13 but is in a through state at a position corresponding to the bottom wall of the water passing groove 13, so that the water return chamber passing hole 181 communicates with the water return chamber 18.

When water flows into the water passing chamber 235 from the inclined water hole 236, it first impacts the vane 11 and pushes the rotating member 10 to rotate in the first direction, then most of the water flows will flow out from the first water passing hole 237, and less of the water flows will impact the side wall of the water passing hole 181 of the water returning chamber through the inclined water groove 233, applying rotational resistance to the rotating member 10, then the water flows will enter the water returning chamber 18 from the water passing hole 181 of the water returning chamber, and then flow out through the first water passing hole 237.

Example four

The fourth embodiment is different from the first embodiment in that the second water outlet passage is formed in a different structure.

In this embodiment, the water passing groove 13 extends to the bottom end of the rotating member 10 along the axial direction of the rotating member 10, and a water passing gap is not formed between the rotating surface 14 of the rotating member 10 and the inner wall of the second water outlet hole 234, so that the rotating member 10 is tightly fitted with the second water outlet hole 234, but the rotating member 10 can still rotate relative to the base 23. At this time, the water passing groove 13 itself and the inner wall of the second water outlet hole 234 cooperate to form a second water outlet channel. When the water flow passes through the inclined water tank 233 and impacts the side wall of the water passing tank 13, the water flow flows to the bottom end of the rotating member 10 along the water passing tank 13 and is discharged to the outside of the water discharging device.

EXAMPLE five

The fifth embodiment is different from the first, second, and fourth embodiments in the manner of forming the water passing groove 13.

As described in the first, second and fourth embodiments, the water passing groove 13 is formed by directly recessing the rotating surface 14, in this embodiment, a plurality of protrusions are provided on the rotating surface 14, and the water passing groove 13 is formed by the interval between the protrusions. Further, the above-mentioned projection extends in the axial direction of the rotation member 10, which causes the formed water passing groove 13 to also extend in the axial direction. The position of the water stream impact guided by the inclined water tank 233 is a convex side wall.

Of course, the water passing groove 13 formed by the protrusion may be configured to extend to the bottom end of the rotating member 10 or both ends may be closed according to specific situations.

It should be noted that, with any of the above-mentioned embodiments, by adjusting the water passing area of the second water outlet channel, the width dimension of the water passing groove 13, and the width dimension of the inclined water groove 233, the amount of the rotation resistance formed after the water flow guided by the second inclined water channel impacts the rotating member 10 can be adjusted, so as to adjust the deceleration degree of the rotating member 10.

In addition, the invention also provides a shower head, which comprises any one of the water outlet devices in the first embodiment to the fifth embodiment.

According to the water outlet device and the shower head provided by the invention, the rotating piece 10 is impacted by two water flows at the same time and the pushing forces in opposite directions are applied to the rotating piece 10, so that the rotating piece can have a lower rotating speed compared with the common condition that only one water flow applies force.

The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
