Embodiments of the present invention

In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

Please refer to Figures 1 to 5, a water outlet structure 1 includes a water spray former 2 and a water outlet end 11, the water spray former 2 is rotatably arranged on the water outlet end 11, the water spray former 2 includes a first water pass surface 21, a second water pass surface 22 and a water pass passage, the first water pass surface 21 and the second water pass surface 22 are connected through the water pass passage.

As shown in FIG2 , when the first water pass surface 21 is located at the water outlet side, the second water pass surface 22 is located at the water inlet side; as shown in FIG5 , when the second water pass surface 22 is located at the water outlet side, the first water pass surface 21 is located at the water inlet side.

As shown in Figure 2, when the first water passing surface 21 is located at the water outlet side, the water outlet structure 1 can produce a diffused water splash that diverges outward, the water beam of the water splash is more dispersed, and the water flow is softer; as shown in Figure 5, when the second water passing surface 22 is located at the water outlet side, it can produce a concentrated water splash that converges toward the center, the water beam of the water splash is more concentrated, and the water flow is more impactful.

The working principle of the present invention is that: this scheme adopts a rotatable water spray former set at the water outlet end of the water outlet structure, and by applying force to the water spray former to flip the water spray former, the water surface can be flipped to exchange the water inlet side and the water outlet side, thereby changing the water outlet spray.

From the above description, it can be seen that the beneficial effects of the present invention are: compared with existing products that can achieve the same function, the present solution has greatly simplified the structure; and because the positions of the water inlet side and the water outlet side of the two water pass surfaces can be repeatedly exchanged, the present solution also has a debris removal function, that is, when any water pass surface rotates from the water inlet side to the water outlet side, the water flow will flush the impurities originally on the water pass surface on the water inlet side and make them fall off the water pass surface, thereby avoiding the water outlet channel being blocked by impurities and causing poor water outlet or deformed water splashes.

Furthermore, a plurality of openings 23 are provided on the first water passing surface 21 and the second water passing surface 22, and the angle between the end surface normal direction of the openings 23 and the inlet water flow direction is not 0°.

It can be seen from the above description that adopting such a solution can better make the splashes generated by different water surfaces have greater differences in appearance.

Furthermore, the angle between the end surface normal direction of the plurality of openings 23 and the incoming water flow direction is 1-10°.

From the above description, it can be seen that although the larger the angle of the above-mentioned angle, the greater the difference in the generated water splashes, the higher the processing difficulty. Therefore, adopting such a solution can take into account the difficulty of simultaneously forming different water outlet ends, the distinction between different water splashes that can be generated, and the practicality of the water splashes.

Furthermore, as shown in FIG. 2 to FIG. 5 , at least a portion of the first water passing surface 21 and/or the second water passing surface 22 of the water spray former 2 is a curved surface.

It can be seen from the above description that setting the water passing surface as a curved surface can more easily allow the first water passing surface and the second water passing surface to generate different water splashes.

Further, as shown in Figures 2 to 6, the first water pass surface 21 and the second water pass surface 22 are located on opposite side end surfaces of the same water pass panel, and the water pass passage is a through hole 24 located in the water pass panel for connecting the first water pass surface 21 and the second water pass surface 22.

From the above description, it can be seen that this solution adopts the design of a single water-passing panel, which has the simplest structure.

Further, as shown in Figures 7 to 11, the first water flow surface 21 is located on the first water flow panel 25, the second water flow surface 22 is located on the second water flow panel 26, and the water flow passage includes a through hole 24 located in the first water flow panel 25 and a through hole 24 located in the second water flow panel 26.

From the above description, it can be seen that this solution adopts a double water-passing panel design. The two water-passing panels can be provided with completely different forms of through holes as needed, which can better produce different water splashes through the first water-passing surface and the second water-passing surface.

Furthermore, as shown in FIGS. 7 to 11 , the water flow passage further includes a water flow cavity 27 between the first water flow panel 25 and the second water flow panel 26 .

From the above description, it can be seen that the water passage cavity can separate the distance between the two water passage panels, so that the water flow passing therethrough has a certain divergence space, thereby preparing for the rectification when the water flow enters and passes through the water passage panel on the opposite side and the water splash shape is better changed.

Furthermore, as shown in FIGS. 7 to 11 , a rectifying insert 28 is provided in the water passage cavity 27 .

From the above description, it can be seen that setting a rectifying insert can better cut, slow down, pressurize, reduce noise, mix air, etc. the water flow passing through the water flow chamber, thereby better changing the shape of the water splash and preparing for rectification when the water flow enters and passes through the water flow panel on the opposite side.

Furthermore, a protruding column 29 extends from the first water passing surface 21 and/or the second water passing surface 22 in a direction away from the water spray former 2 .

From the above description, it can be seen that the setting of the convex column can utilize the lever principle to reduce the turning force required to rotate the water splash former. The longer the convex column, the smaller the turning force required; but the length of the convex column must be smaller than the radius of the water outlet end face, otherwise the water splash former will not be able to swap the positions of the two water passing surfaces.

Furthermore, as shown in FIGS. 7 to 11 , the boss 29 is located at the center of the first water passing surface 21 and/or the second water passing surface 22 .

From the above description, it can be seen that the convex column is arranged at the center so that the water splash former can be turned over more easily no matter in which direction the force is applied, and the convex column is arranged at the center so that it can extend to the length of the radius closest to the water outlet end surface.

On the contrary, if it is set eccentrically, force needs to be applied in a specific direction to flip the water splash former more easily, and the maximum length that the protrusion can extend is also less than that set at the center.

Furthermore, as shown in FIGS. 10 and 11 , the outer peripheral surface of the water spray former 2 is in an incomplete spherical shape, and as shown in FIGS. 7 to 9 , the inner side surface 12 of the water outlet end 11 is a spherical socket surface for installing the water spray former 2 .

From the above description, it can be seen that the contact surface between the water splash former and the water outlet is set as a spherical surface and a ball socket, which can achieve the lightest rotation feel and rotation in any direction, and can greatly improve the user's switching experience.

In other embodiments, the two can still be matched in other aspherical surfaces (such as elliptical surfaces, conical surfaces, etc.), and the flipping and switching process can also be completed along a specific direction.

Furthermore, as shown in FIG. 7 to FIG. 9 , a plurality of grooves 13 are provided on the socket surface.

From the above description, it can be seen that providing a groove can reduce the contact area between the outer surface of the water splash former and the ball socket surface, thereby reducing the friction between the two during relative movement, and ultimately reducing the flipping force required for the switching process, further improving the user's switching experience.

Furthermore, as shown in FIGS. 2 to 5 and 7 to 9 , a sealing member 3 is also included. The sealing member 3 is elastic and is disposed between the water spray former 2 and the water outlet 11 .

It can be seen from the above description that the seal can prevent water leakage between the water spray former and the water outlet during the water flow process.

Furthermore, the seal 3 is an annular plastic seal, an annular rubber seal or an annular silicone seal.

It can be seen from the above description that the seal is set to be annular, which can reduce the contact area between the seal and the water spray former and reduce the resistance caused by the seal during the switching process.

Further, as shown in FIGS. 2 to 5 , the seal 3 is arranged on the outer peripheral surface of the water spray former 2 , or as shown in FIGS. 7 to 9 , the seal 3 is arranged on the inner side surface of the water outlet end 11 .

From the above description, it can be seen that the fixed position of the seal can be selected according to the actual design of the water outlet structure to maintain a balance between high sealing performance and better switching experience.

Furthermore, as shown in FIG. 2 to FIG. 9 , there is at least a portion of a gap 4 between the outer peripheral surface of the water spray former 2 and the inner side surface 12 of the water outlet end 11 , and the gap 4 decreases as the water pressure increases.

From the above description, it can be seen that when a seal is set to prevent water leakage between the water splash former and the water outlet end during water flow, there is a gap between the inner side surfaces of the water splash former and the water outlet end, and when in the water flow state, under the action of water pressure, the entire water splash former will be pressed toward the water outlet direction by the water pressure. Therefore, the gap between the water splash former and the inner side surfaces of the water outlet end toward the water outlet direction will become smaller and smaller as the water pressure increases, which can make the water splash former better pressed against the seal to eliminate the possibility of water leakage; when as shown in Figure 6 It is shown that when no seal is set, only part of the contact surface between the water splash former and the inner side surface of the water outlet end has a gap, and the other contact surfaces need to fit completely without leaving any gaps in order to achieve sealing. When the water is flowing, under the action of water pressure, the outer peripheral surface of the entire water splash former will be pressed toward the water outlet direction by the water pressure. Therefore, the position where there is originally a gap between the water splash former and the inner side surface of the water outlet end will become smaller and smaller as the water pressure increases, which can make the water splash former better pressed against the inner side surface of the water outlet end, thereby reducing the possibility of water leakage.

Furthermore, as shown in Figures 2 to 9, it also includes a limiting portion 14, which is arranged in the water outlet structure 1, and the limiting portion 14 is located on the water inlet side of the water splash former 2, and the inner diameter of the limiting portion 14 is smaller than the outer diameter of the water splash former 2.

From the above description, it can be seen that when flipping the water splash former, if the user uses excessive force, the water splash former may be pushed into the water outlet structure, causing it to be out of the working position and causing the entire water outlet structure to fail. Therefore, in order to avoid this problem, the present invention provides a limit part in the water outlet structure to limit the water splash former in the axial direction of the water outlet structure.

Please refer to Figures 1 to 5, the first embodiment of the present invention is:

A water outlet structure 1 can be installed on a faucet for use as a bubbler.

As shown in Fig. 1 and Fig. 2, a water splash former 2 is provided in the water outlet end 11 of the water outlet structure 1. The water splash former 2 is rotatably provided in the inner side surface 12 of the water outlet end 11 of the water outlet structure 1. The circumferential outer surface of the water splash former 2 is an outwardly convex arc surface. The inner side surface 12 of the water outlet end 11 is provided as an inwardly concave arc surface matching the arcuate outer surface of the water splash former 2. An annular rubber seal 3 is provided between the outer surface of the water splash former 2 and the inner side surface 12 of the water outlet end 11. The seal 3 is fixed in the limiting groove on the outer surface of the water splash former 2. A limiting portion 14 is provided in the water outlet structure 1. The limiting portion 14 is located on the water inlet side of the water splash former 2. The inner diameter of the limiting portion 14 is smaller than the outer diameter of the water splash former 2. The limiting portion 14 is used to limit the water splash former 2 in the axial direction along the water outlet structure 1.

The water spray former 2 is provided with an arc-shaped water-passing panel, and the opposite end surfaces of the water-passing panel are a first water-passing surface 21 that is convex outwardly and arc-shaped as a whole, and a second water-passing surface 22 that is concave inwardly and arc-shaped as a whole. The water-passing panel is formed with a plurality of densely distributed through holes 24 that connect the first water-passing surface 21 and the second water-passing surface 22 to form a water-passing passage. The end surface normal direction of the openings 23 located at both ends of the through holes 24 on the first water-passing surface 21 and the second water-passing surface 22 is at an angle of 1° with the direction of the incoming water flow.

As shown in FIG. 2 , the first water passing surface 21 is located at the water outlet side, and the second water passing surface 22 is located at the water inlet side. At this time, in the water flow state, a diffuse water spray radiating outward can be generated.

As shown in FIG. 3 and FIG. 4 , the water spray former 2 will rotate after an external force is applied thereto, and the first water passing surface 21 and the second water passing surface 22 will gradually change the positions of the water inlet side and the water outlet side during the turning process.

As shown in FIG5 , after the water splash former 2 has completed a 180-degree flip, the second water passing surface 22 is turned to the water outlet side, and the first water passing surface 21 is turned to the water inlet side. At this time, in the water-flowing state, a concentrated water splash that converges toward the center can be generated.

Obviously, in order to achieve the degree of diffusion and contraction of water splashes that meets the water outlet function of the product in different usage scenarios, the angle between the end face normal direction of each opening 23 and the water inlet direction can also be set to 2°, 3°, 4°, 5°, 6°, 7°, 8° or 9° in the range of 1~10°.

The above-mentioned rotation action of the water spray former 2 can be realized regardless of whether water is flowing through the water outlet structure 1 or not.

This solution can change the water spray of the water outlet structure 1 by rotating the water spray former 2. Compared with existing bathroom products that can also achieve water spray switching, the structure is greatly simplified. In addition, since the two water flow surfaces can be repeatedly switched between the water inlet side and the water outlet side, this solution can also use water flow to flush impurities on the water flow surface originally located on the water inlet side and make them fall off the water flow surface, thereby avoiding the water outlet channel being blocked by impurities, resulting in poor water flow or deformed water spray.

Please refer to FIG. 6 , the second embodiment of the invention is:

A water outlet structure 1 can be installed on a faucet for use as a bubbler.

The difference between this embodiment and embodiment one is that the first water passing surface 21 and the second water passing surface 22 of the water splash former 2 are both planes, and the angle between the end surface normal direction of the openings 23 located at both ends of the through hole 24 on the first water passing surface 21 and the second water passing surface 22 and the direction of the water inlet flow is 1.5°; at the same time, in this embodiment, the rubber seal is cancelled between the water splash former 2 and the water outlet end 11, and the outer peripheral surface of the water splash former 2 and the inner side surface 12 of the water outlet end 11 are sealed by friction fit. Therefore, in this embodiment, there is only a partial gap 4 between the outer peripheral surface of the water splash former 2 and the inner side surface 12 of the water outlet end 11, and the gap 4 is smaller than the gap in embodiment one. When in the water-passing state, under the action of water pressure, the outer peripheral surface of the entire water splash former 2 will be pressed toward the water outlet direction by the water pressure. Therefore, the position where there was originally a gap between the water splash former 2 and the inner side surface 12 will become smaller and smaller with the increase of water pressure, which can make the water splash former 2 better pressed against the inner side surface 12 to reduce the possibility of leakage.

In addition, in this embodiment, the entire water splash former 2 is an integrally formed part, and its water-passing panel and the outer peripheral surface protruding outward can be integrally formed by injection molding.

Please refer to Figures 7 to 11, the third embodiment of the present invention is:

A water outlet structure 1 can be installed on a faucet for use as a bubbler.

As shown in Figures 7 to 11, a water splash former 2 is provided inside the water outlet end 11 of the water outlet structure 1. The water splash former 2 is rotatably provided in the inner side surface 12 of the water outlet end 11 of the water outlet structure 1. The circumferential outer surface of the water splash former 2 is a spherical surface protruding outward. The inner side surface 12 of the water outlet end 11 is provided as a spherical socket surface that matches the arc-shaped outer surface of the water splash former 2 and is concave inward. A plurality of grooves 13 are provided on the spherical socket surface. An annular silicone seal 3 is provided between the outer surface of the water splash former 2 and the inner side surface 12 of the water outlet end 11. The seal 3 is fixed in the limiting groove of the inner side surface 12. The limiting groove in this embodiment is formed by the gap between the lower end of the embedded part of the water outlet structure 1 and the annular convex lip at the lower end of the outer shell of the water outlet structure 1. The seal 3 is pressed by the lower end of the embedded part to prevent it from falling out of the limiting groove. A limiting portion 14 located on the embedded component is provided in the water outlet structure 1. The limiting portion 14 is located on the water inlet side of the water splash former 2. The inner diameter of the limiting portion 14 is smaller than the outer diameter of the water splash former 2. The limiting portion 14 is used to limit the water splash former 2 in the axial direction along the water outlet structure 1.

The first water passing surface 21 of the water splash former 2 is located on the first water passing panel 25, and the second water passing surface 22 is located on the second water passing panel 26. The water passing passage is composed of a through hole 24 located in the first water passing panel 25, a through hole 24 located in the second water passing panel 26, and a water passing cavity 27 located between the first water passing panel 25 and the second water passing panel 26. A rectifying insert 28 is provided in the water passing cavity 27. The two water passing panels 25 and 26 can be provided with through holes 24 of completely different shapes as required, so as to better produce different water splashes through the first water passing surface 21 and the second water passing surface 22. Bosses 29 are respectively extended from the first water passing surface 21 and the second water passing surface 22 in a direction away from the water splash former 2, and the two bosses 29 are respectively located at the center of the first water passing surface 21 and the second water passing surface 22.

10 and 11, in the present embodiment: the first water-passing panel 25 is configured as a porous structure (the number of holes is more than 100, and the pore diameter is between 0.2 and 0.5 mm), each through hole 24 is cylindrical/conical, and hundreds of fine water columns can be generated from the first water-passing surface 21, and the water spray is dense, and dense water mixed with air and airless strong water can be generated according to whether the water outlet structure 1 inhales air. The dense water can be used to wash food or wash hands, and the strong water can be used to rinse tableware or a sink; the second water-passing panel 26 is configured as a mesh structure having thorns radiating from the center of a circle to the surroundings and connecting each radiating thorn through a circular connecting plate between the thorns, each through hole 24 is cylindrical, and a single thick water column can be generated from the second water-passing surface 22, and the water spray is surging, and bubble water mixed with air and airless transparent water can be generated according to whether the water outlet structure 1 inhales air, the bubble water is more water-saving and not easy to splash, and the transparent water has a large water flow rate and no noise.

As shown in FIG. 7 and FIG. 10 , the first water passing surface 21 is located at the water outlet side, and the second water passing surface 22 is located at the water inlet side. At this time, water flows out from the first water passing surface 21 .

As shown in FIG. 8 , the water spray former 2 will rotate after an external force is applied through the convex column 29 , and the first water passing surface 21 and the second water passing surface 22 gradually change the positions of the water inlet side and the water outlet side by turning over.

As shown in Figures 9 and 11, when the water spray former 2 completes a 180-degree flip, the second water passing surface 22 is turned to the water outlet side, and the first water passing end 21 is turned to the water inlet side. At this time, water flows out from the second water passing surface 22.

Please refer to Figure 12, the fourth embodiment of the invention is:

A water outlet structure 1 can be used as a shower head.

The specific structure of this embodiment is similar to that of the first embodiment, and the essential difference is that the central part of the first water-passing surface 21 and the second water-passing surface 22 of the water-splash former 2 is an arc surface, and the non-central part is a plane. The normal direction of the end surface of the openings 23 located at both ends of the through hole 24 on the first water-passing surface 21 and the second water-passing surface 22 is at an angle of 2° to the direction of the water inlet flow. Since the water outlet area of the shower is large, the above-mentioned setting can enable the water outlet structure 1 used as a shower to generate a different water splash at the center and around the water-passing panel on the same side, and after flipping, the center and around the water-passing panel on the same side on the other side can generate a different water splash respectively. Therefore, when the first water-passing surface 21 is located on the water outlet side and when the second water-passing surface 22 is located on the water outlet side, this embodiment fully utilizes the large water outlet area of the shower to achieve four different water splash effects, greatly enriching the user experience.

In summary, the present invention can achieve different water sprays on the same water outlet structure with a relatively simple design and higher reliability, and at the same time has a debris removal function, and has good application prospects and a wide range of adaptable uses in bathroom products.

The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
