[0043] In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the front and rear associated objects.

[0044] Please see Figures 1-18 As shown in the figure, the water outlet device of the present application comprises a water outlet body 1 and a water outlet surface cover 2. The water outlet body 1 is provided with a water outlet cavity 11, and the water outlet cavity 11 is provided with a water inlet 12. The water outlet surface cover 2 is reversibly installed in the water outlet end of the water outlet cavity 11 of the water outlet body 1, so that the water outlet surface cover 2 can realize water spray switching by 180° turning. The present application further comprises a switching piece 3, which is movably installed in the water outlet cavity 11 of the water outlet body 1 and is provided with a transmission structure between the water outlet surface cover 2. The switching piece 3 has an operation part 31 located outside the water outlet cavity 11, which can be operated to make the switching piece 3 drive the water outlet surface cover 2 to turn over. With the turning over of the water outlet surface cover 2, the switching piece 3 controls the flow of the water inlet 12 to change from large to small and then to large. That is, during the turning over process of the water outlet surface cover, the switching piece 3 controls the flow of the water inlet 12 to become small, thereby avoiding the splashing of water spray. When the water outlet surface cover 2 is turned over, the switching piece 3 controls the flow of the water inlet 12 to become large to the state before the water outlet surface cover 2 is turned over, thereby ensuring a large water outlet flow to meet the water spray shape forming and use requirements.

[0045] As a preferred mode, the switching member 3 is rotatably connected to the water outlet body 1 along its axis, and the axis of the switching member 3 is perpendicular to the axis of the overturning shaft of the water outlet face cover 2. The transmission structure is arranged between the first end of the switching member 3 along its axis and the water outlet face cover 2, and the water outlet cavity 11 is provided with an opening at the end away from the water outlet face cover 2. The second end of the switching member 3 along its axis extends out of the opening end of the water outlet cavity 11 and forms the operation part 31. Specifically, the switching member 3 is in a cylindrical shape, and the operation part 31 is in a knob shape, but is not limited to this. In other embodiments, the switching member can be movably connected to the water outlet body along its axis.

[0046] In this embodiment, the water outlet face cover 2 is connected to the water outlet face cover 2 by the overturning shaft 211, and the axis of the overturning shaft 211 is in the radial direction of the water outlet face cover 2 and is perpendicular to the axis of the switching member 3. The transmission structure is arranged between the first end of the switching member 3 and the overturning shaft 211, and the transmission structure is a gear transmission structure. The overturning shaft 211 is provided with two coaxial overturning shafts 211 distributed on the opposite sides of the water outlet face cover 2, and the transmission structure is arranged between the first end of the switching member 3 and one of the overturning shafts 211. Specifically, the gear transmission structure includes a ring of protrusions 32 arranged at the first end of the switching member 3 and a gear 212 arranged on the overturning shaft 211, and the protrusions 32 are engaged with the gear 212. When the switching member 3 is movably connected to the water outlet body 1 along its axis, it can also be used with the water outlet face cover by using a gear transmission structure. At this time, the gear transmission structure can include, for example, a gear arranged on the overturning shaft of the water outlet face cover and a gear rack arranged on the switching member, the gear rack extending in the movement direction of the switching member and being engaged with the gear.

[0047] The water outlet face cover 2 can output a first water flow at one end in its axial direction and a second water flow at the other end, and the first water flow and the second water flow are different water types. Specifically, the water outlet face cover 2 is provided with a first water outlet hole 213 at one end in its axial direction, which can form a first water flow, and a second water outlet hole 221 at the other end, which can form a second water flow, so that the water outlet face cover 2 can be switched from the first water flow to the second water flow or from the second water flow to the first water flow when it is overturned 180 degrees around the axis of the overturning shaft 211. Figures 3-5As shown, the water outlet surface cover 2 specifically comprises a surface cover main body 21 and a water outlet piece 22. One end of the surface cover main body 21 is a water outlet end for outputting a first water flow, and the other end is provided with an opening. The water outlet end of the surface cover main body 21 is provided with a first water outlet hole 213 for forming the first water flow. The water outlet piece 22 is installed in the opening at the other end of the surface cover main body 21 and is used to output a second water flow. Specifically, the water outlet piece 22 is provided with a plurality of second water outlet holes 221 for forming the second water flow. The water outlet surface cover 2 is turned over to make the first water outlet hole 213 or the second water outlet hole 221 face outward to output water. The two turning shafts 211 are provided on the surface cover main body 21. The first water flow is specifically a columnar water flow, and the second water flow is specifically a shower water flow, but is not limited thereto. Therefore, the first water outlet hole 213 is a plurality of first water outlet holes 213 which substantially constitute a mesh-shaped water outlet. Each second water outlet hole 221 is a circular hole, and the plurality of second water outlet holes 221 are distributed in a diverging manner. The water outlet piece 22 is specifically limited by a cap 26 at the other end of the surface cover main body 21. The cap can be fixed with the surface cover main body 21 by ultrasonic welding.

[0048] The surface cover main body 21 is provided with a filter assembly. The filter assembly specifically comprises a first filter piece 23, a second filter piece 24, and a support 25 for separating the first filter piece 23 and the second filter piece 24 and for rectifying the water flow. The support 25 specifically comprises a cylindrical body and a central shaft provided on the center line of the cylindrical body. The central shaft and the cylindrical body are provided with a plurality of support pieces which are distributed in a diverging manner.

[0049] In the present embodiment, the switching piece 3 is provided with a water passing cavity 33 and a water passing hole 34 connected through the water passing cavity 33. The end of the switching piece 3 adjacent to the water outlet surface cover 2 (i.e. the first end of the switching piece 3) is provided with an opening connected through the water passing cavity 33. The switching piece 3 is moved (i.e. rotated or moved) to make the water passing hole 34 of the switching piece 3 staggered or opposite to the water inlet 12. When the water passing hole 34 is completely staggered with the water inlet 12, the water inlet 12 is equivalent to being closed, so that the flow of the water inlet 12 reaches the minimum. When the water passing hole 24 is completely opposite to the water inlet 12, the water inlet 12 is equivalent to being opened, so that the flow of the water inlet 12 reaches the maximum. As described above, the switching piece 3 is in a cylindrical shape, so that the inner cavity thereof constitutes the water passing cavity 33. The water passing hole 34 is a plurality of water passing holes 34 which are uniformly distributed along the circumference of the switching piece 3.

[0050] The present invention also includes a flow-regulating structure, which is disposed within the switching element 3 or the water outlet body 1. Specifically, in this embodiment, the flow-regulating structure is disposed within the water passage cavity 33 of the switching element 3. This flow-regulating structure can disperse and / or restrict the water flow, thereby ensuring a consistent flow velocity at each point, thus ensuring the shape of the water splash, and preventing the switching feel of the switching element 3 from being too heavy and further reducing the possibility of water splashing. Without the flow-regulating structure, it is easy to cause the switching feel to be too heavy or the water splash shape to be ineffective.

[0051] Specifically, the flow-slowing structure includes a primary flow-slowing component 4, such as... Figures 7-9 As shown, the first-stage flow-retardant 4 includes an inlet component 41 and an outlet component 42 connected together. A water passage gap 44 is provided between the inlet component 41 and the outlet component 42. An elastically deformable O-ring 43 is provided in the water passage gap 44. Multiple inlet holes 411 connected to the water passage gap 44 are provided on the inlet end face of the inlet component 41. These inlet holes 411 can realize the function of dispersing water flow and realize the flow restriction adjustment of water flow by utilizing the elastic deformation of the O-ring 43.

[0052] The flow-slowing structure of the present invention also includes a secondary flow-slowing element 5. The primary flow-slowing element 4 and the secondary flow-slowing element 5 are distributed sequentially along the water flow direction. The secondary flow-slowing element 5 is provided with a mesh-like water outlet 51, which can further disperse the rectified water flow, ensuring that the flow velocity of the water flow at each point in the flow channel is consistent, thereby ensuring the water splash pattern. Specifically, as shown... Figure 10 As shown, the secondary flow slowing component 5 has a hollow inner cavity, and one end of it is the water outlet end, which is provided with a mesh water inlet 51. The other end is provided with an opening, and the aforementioned primary flow slowing component 4 is fitted onto the opening at the other end of the secondary flow slowing component 5.

[0053] As a preferred embodiment, the switching element 3 is detachably connected to the water outlet body 1, allowing the slow-flow structure to be removed along with the switching element 3 during periodic cleaning. This facilitates disassembly and cleaning of the slow-flow structure, resolving the issue that reverse cleaning cannot resolve blockages in the slow-flow structure. To facilitate the removal of the slow-flow structure from the switching element 3, an opening is provided at the end of the switching element 3 furthest from the water outlet cover 2 (i.e., the second end of the switching element 3). The slow-flow structure enters and exits the water passage cavity 33 of the switching element 3 through this opening. The opening at the second end of the switching element 3 can be sealed with a plug.

[0054] The specific connection relationship between the switching piece 3 and the water outlet body is as follows: a plurality of elastic buckles 35 are arranged on the side wall of the switching piece 3 and distributed along the circumference of the switching piece 3, and the elastic buckles 35 are detachably buckled on a ring of buckle grooves 13 arranged on the inner wall surface of the water outlet cavity 11 of the water outlet body 1. Further, one end of the buckle groove 13 for the elastic buckle 35 to enter and exit is provided with a C corner (i.e. a 45° chamfer) to facilitate the elastic buckle 35 to enter and exit. The present application further comprises a fastener 6 which is screwed from the opening of the switching piece 3 away from the water outlet surface cover 2 into the switching piece 3 and limits the elastic deformation of the elastic buckle 35 in the direction of disassembly. The fastener 6 constitutes the above-mentioned plug, specifically, one end of the fastener 6 faces the slow-flow structure and can limit the slow-flow structure, and the other end of the fastener 6 is provided with an operation groove 61 to facilitate the user to rotate the fastener 6 with the help of a tool. The present application further comprises a decorative cover 7 which is sleeved at the second end of the switching piece 3 and covers the fastener 6. Therefore, when the fastener 6 needs to be disassembled, the decorative cover 7 is first removed.

[0055] Further, the water outlet body 1 is provided with a spring impact bead 9, and a plurality of positioning grooves 36 are uniformly distributed along the circumference of the outer side surface of the switching piece 3, and the spring impact bead 9 is clamped into one of the positioning grooves 36. In this way, not only can the spring impact bead 9 be used to position the switching piece 3, but also the gear feeling can be increased, and the rotation to position indicating function can be achieved. The spring impact bead 9 specifically consists of a spring 91 and a positioning pin 92.

[0056] The water outlet body 1 of the present application is generally T-shaped, including a head portion and a handle portion, the head portion is provided with the above-mentioned water outlet cavity 11, and the handle portion is provided with a water inlet channel 101 which communicates with the above-mentioned water inlet 12. Specifically, a water inlet core 10 is arranged in the handle portion, and the water inlet core 10 forms the water inlet channel 101. In order to prevent water leakage, the present application is provided with a sealing ring 8 between the switching piece 3 and the water outlet body 1, and the sealing ring 8 is a Y-shaped ring (i.e. the cross section of the sealing ring 8 is Y-shaped), but is not limited thereto. The sealing ring 8 is provided with two, and the two sealing rings 8 are respectively sleeved outside the switching piece 3, and one of the sealing rings 8 is located outside the first end of the switching piece 3, and the other sealing ring 8 is close to the opening end of the water outlet cavity 11.

[0057] The working principle of the water outlet device of the present application is as follows:

[0058] In the initial state, the water outlet hole at one end of the water outlet surface cover 2 faces outward (taking the first water outlet hole 213 as an example for description, but not limited thereto), one of the water passing holes 34 on the switching piece 3 is opposite to the water inlet 12 of the water outlet cavity 11, and the tail end of the spring impact bead 9 is clamped into one of the buckle grooves 13, as shown in Figure 13 、 Figure 14As shown. When water enters the inlet channel 101, the water flows from the inlet 12 into the outlet chamber 11 of the outlet body 1, and mainly flows from the inlet 12 opposite to the inlet 12 into the water passage chamber 33 of the switching component 3. Then, it passes through the first-stage flow buffer 4 to disperse and limit the flow, and the second-stage flow buffer 5 to further rectify and disperse the flow before flowing to the outlet cover 2. Then, it enters the outlet cover 2 from each of the second outlet holes 221, and after being rectified and filtered by the filter assembly, it is finally output from each of the first outlet holes 213 of the outlet cover 2, forming a columnar water spray.

[0059] When the user needs to switch the water flow, with water continuously flowing into the inlet channel 101, simply rotate the switching element 3: rotate the operating part 31 of the switching element 3 counterclockwise or clockwise to rotate the switching element 3 by a certain angle (approximately 40°). As the switching element 3 rotates, the ring of protruding teeth 32 at its first end drives the gear 212 to rotate, thereby causing the water outlet cover 2 to rotate 180°, causing the second water outlet hole 221 on the water outlet cover 2 to rotate out. During this process, the water passage hole 34 of the switching element 3 is first offset from the water inlet 12 (the offset state is as follows). Figures 16-18 As shown, the flow rate of the inlet 12 decreases and then increases again. When the switching element 3 rotates halfway or nearly halfway (the switching element 3 rotates approximately 20°), the outlet cover 2 rotates approximately 90°. At this point, the water passage 34 of the switching element 3 is completely misaligned with the inlet 12, minimizing the flow rate of the inlet 12. Subsequently, as the switching element 3 continues to rotate, the water passage 34 gradually returns to its position opposite to the inlet 12, gradually increasing the flow rate of the inlet 12 until the outlet cover 3 is fully rotated. Therefore, during the rotation of the outlet cover 2, although water continues to enter the inlet channel 101, the significantly reduced flow rate at the inlet 12 prevents water from splashing during the rotation of the outlet cover 2. After the switching element 3 is fully rotated, the spring ball 9 engages with the next positioning groove 36, creating a tactile feedback and indicating to the user that the switching element 3 has been rotated to the correct position.

[0060] Therefore, the flipping operation of the water outlet cover 2 and the flow control of the water inlet 12 in this invention are both achieved by the switching component 3, making the user operation more convenient and allowing for one-step operation. In particular, during operation, the switching component 3 can be rotated in any direction and has a rotation completion reminder function, making the user operation very convenient.

[0061] When the primary and / or secondary slow flow fluid is blocked by impurities, the user can pull out the switch 3 after removing the fastener 6, and then remove the primary and secondary slow flow fluid from the water outlet cavity 11 of the water outlet body 1, and then remove the primary and secondary slow flow fluid from the switch 3, so that the primary and secondary slow flow fluid can be flushed respectively. When the water outlet surface cover 2 is blocked, the water outlet surface cover 2 can be turned by 180° by rotating the switch 3 to realize reverse flushing of the water outlet surface cover 2 to achieve the function of descaling.

[0062] The water outlet device of the present application is a shower head, but is not limited to this. In other embodiments, the water outlet device of the present application is a faucet or other.

[0063] The water outlet device of the present application does not involve parts that are the same as or can be realized by the prior art.

[0064] The above embodiments are only used to further illustrate the water outlet device of the present application, but the present application is not limited to the embodiments. Any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application all fall within the protection scope of the technical scheme of the present application.
