Description

[Technical Field]

[0001] The present invention relates to the field of sanitary products, and in particular to a water discharge structure. Growth Regarding. [Background technology]

[0002] In order to improve the water discharge efficiency of terminal water discharge devices (products such as shower heads and foaming devices) in low-pressure or normal-pressure water supply environments, a common prior art approach involves reducing the diameter of a single water discharge hole in the terminal water discharge device's water discharge panel. For example, a thin steel sheet may be used as the water discharge panel, with hundreds of water discharge holes each 0.3 to 0.5 mm in diameter. With this configuration, when water enters the water receiving chamber upstream of the water discharge panel, the entire water passes through the discharge holes of the specified diameter, constricting the water within the holes, increasing the pressure within the water. This allows the water to maintain a relatively high pressure even when it flows downstream of the water discharge panel, significantly increasing the spray stroke and improving the water discharge efficiency. For example, the Chinese patent document 201620732430.7 discloses such a solution.

[0003] However, when the above configuration is applied to a water discharge device equipped with an air intake mechanism, the relatively high water pressure in the water receiving chamber causes the drainage speed of the water discharge hole to be lower than the water supply speed upstream of the water receiving chamber. This causes water pressure to build up in the chamber, causing water to return to the water receiving chamber upstream and leak out along the air intake passage of the air intake mechanism, resulting in water leakage into the water discharge device. Furthermore, problems with the quality of the water supply can easily cause blockages in the water passage of the above configuration. For example, if the water supply environment contains relatively high levels of impurities, the impurities can completely block the water discharge hole. If the water supply environment contains relatively hard water, the water remaining in the water discharge hole after use can calcify (harden) and gradually clog the water discharge hole. Furthermore, after long-term use, scale (soft material) formed in the water discharge hole can gradually clog the water discharge hole, preventing the water discharge device from flowing smoothly. Summary of the Invention [Problem to be solved by the invention]

[0004] The technical problem to be solved by the present invention is to provide a water discharge structure that can realize water discharge by boosting pressure while ensuring that the functions of air intake and water saving are properly used in the water discharge device.

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to describe in detail the technical contents, objects to be achieved, and effects of the present invention, the following description will be given with reference to the accompanying drawings and embodiments.

[0010] Referring to Figures 1 and 2, Figures 3 and 4, and Figures 5 and 6, respectively: The water discharge configuration includes a water supply side and a water discharge side that are connected to each other, with a plurality of water supply ports provided on the water supply side and a plurality of water discharge ports provided on the water discharge side, and the sum of the areas of the water discharge ports is greater than the sum of the areas of the water supply ports. Referring to Figures 1 and 2, Figures 3 and 4, and Figures 5 and 6, respectively: The water discharge configuration includes a jet panel 10, a chamber 20, and a water discharge panel 30. The jet panel 10 is provided with a plurality of jet holes 11, the chamber 20 is connected to the jet side 12 of the jet holes, the space on one side of the chamber 20 facing the water discharge direction is limited by the water discharge panel 30, the water discharge panel 30 is provided with a plurality of jet holes 31, and the jet holes 11 A chamber 20 is provided on the water discharge side 12 of the While not intervening, The external space of the water discharge configuration is connected It is possible , each Water discharge panel at water discharge hole 31 30 A hole located on the surface of the outlet side 32 of the (i.e., the water outlet) The sum of the areas of all the supercritical panels in the supercritical holes 11 10 The hole located on the surface of the outlet side 13 (i.e., water inlet) The area of ​​a single water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel is 0.04 mm 2 ~0.3mm 2 is.

[0011] The working principle of the present invention is as follows: The area of ​​the water outlet is 0.04 mm 2 ~0.3mm 2 The combination of a panel structure that discharges water from a small hole and an intake structure allows the water flow to flow through a jet stream. 11 When water passes through the jet panel, negative pressure is generated on the discharge side of the jet hole, and air in the external space of the water discharge structure is adsorbed on the discharge side of the jet hole, so that the water flow and air are sufficiently mixed in the chamber with limited space. Among them, the intake structure refers to an intake passage that communicates with the external space of the discharge structure, and this intake passage does not require a chamber on the discharge side of the jet hole, but bypasses the chamber and directly communicates with the external space, thereby ensuring smooth intake.In the water discharge panel, the sum of the opening areas of all the water discharge holes located on the surface of the water discharge side of the water discharge panel is greater than the sum of the opening areas of all the water discharge holes located on the surface of the water discharge side of the water discharge panel in the supercritical flow panel, i.e., the total water supply area of ​​the chamber is smaller than the total water discharge area of ​​the chamber. Therefore, due to the pressure that builds up in the chamber, the water flow mixed with water and gas is unlikely to overflow from other passages or openings that can communicate with the water discharge side of the supercritical flow holes and flow into the space outside the water discharge structure. Moreover, each outgoing water flow that is discharged from the small holes in the water discharge panel to the outside of the water discharge structure is accelerated by the water discharge holes and mixed with air.

[0012] As can be seen from the above description, the beneficial effects of the present invention are as follows: First, the effect of saving water can be achieved by mixing air into the jetted water flow. along with The densely packed minute water outlet holes still allow the water jet to have a relatively high degree of overflow and a relatively long jet distance. In addition, compared with the conventional densely packed minute water outlet holes without an air intake function, the water jet mixed with air feels softer and splashes less on the surface of the cleaning surface.

[0013] Furthermore, the sum of the hole opening areas located on the surface of the discharge side 32 of the discharge panel for all the discharge holes 31 is more than twice the sum of the hole opening areas located on the surface of the discharge side 13 of the discharge panel for all the jet holes 11.

[0014] As can be seen from the above description, the total discharge area of ​​the chamber is set to be twice or more than twice the total water supply area, which further reduces the probability of pressure building up in the water flow within the chamber, ensuring that the water flow does not overflow and leak out, and also ensuring that gas can be smoothly adsorbed to the discharge side of the jet flow panel and mixed with the water flow.

[0015] moreover, eachThe hole opening area of ​​the water discharge hole 31 located on the surface of the water supply side 33 of the water discharge panel is Any one It is larger than the hole opening area of ​​the water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel.

[0016] As can be seen from the above, because the inlet area of ​​the spout hole is larger than the outlet area, the side wall of the spout hole can be ensured to have a certain inclination and to contract from the water supply side to the water discharge side. This ensures that the water flow can be smoothly discharged from the spout hole with acceleration. Furthermore, because the area of ​​the water supply side opening of the spout hole is larger than the area of ​​the opening on the water discharge side, it ensures that the separation between adjacent spout holes expands from the inlet side to the outlet side. First, by ensuring that the spacing between the outlet side openings of the spout hole is sufficiently large, it is possible to prevent the spouting water column from sticking. Furthermore, by ensuring that the area of ​​the water facing the water supply side of the spout panel is sufficiently small, it is possible to reduce the resistance that the water flow in the chamber experiences when entering the spout hole and prevent pressure from building up in the water flow in the chamber.

[0017] Furthermore, the opening of the water discharge hole 31 located on the surface of the water supply side 33 of the water discharge panel has a triangular or other It is a polygon.

[0018] As can be seen from the above description, by setting the shape of the opening of the water discharge hole located on the water supply side of the water discharge panel to a triangle or polygon, the surface area on the water supply side can be effectively used to arrange the water supply hole openings of the water discharge hole, thereby increasing the density of the water discharge hole arrangement.

[0019] Furthermore, the shape of the opening of the water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel may be circular, elliptical, triangular, or other It is a polygon.

[0020] As can be seen from the above description, the shape of the opening of the water outlet hole located on the water supply side of the water outlet panel can be determined not only by considering the arrangement density as needed, but also by the actual needs of the shape of the water spray, with circular, elliptical and triangular holes being able to output columnar water flows, and polygonal holes being able to output sheet-like water flows.

[0021] 8 is an enlarged view of the water discharge panel. Distance H is greater than the perimeter of the hole opening contour of the water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel.

[0022] If the outlet hole does not have a certain stroke length (i.e., the distance traveled by the outgoing water stream from when it completely enters the outlet hole until it completely leaves the outlet hole), it will be impossible to adjust the direction and speed of the outgoing water stream, and therefore it will be possible to ensure that the final water shape meets the needs. The perimeter of the outlet hole located on the outlet side of the outlet panel is one of the relatively important influencing factors in forming the water shape.

[0023] As can be seen from the above, setting the axial height of the water discharge hole according to the perimeter of the hole opening contour located on the water discharge side of the water discharge panel can ensure the formation of the correct water shape. In particular, setting the axial height H of the water discharge hole to at least 1.5 times the perimeter of the hole opening contour located on the water discharge side surface of the water discharge panel can obtain the most stable water shape. Furthermore, when the water supply side surface of the water discharge panel is not parallel to the water discharge side surface, the axial height H of the water discharge hole is the length from the point where all four sides of the water column of the water flow completely enter the water discharge hole to the point where all four sides of the water column of the water flow completely leave the water discharge hole.

[0024] 8 and 9 are enlarged views showing the water-spouting panel. The minimum distance between the openings of any two adjacent water-spouting holes 31, 31' located on the surface of the water-spouting side 32 of the water-spouting panel is distance L is larger than the diameter of the largest inscribed circle of the hole opening contour located on the surface of the water-spouting side 32 of the water-spouting panel in the two corresponding water-spouting holes 31, 31'.

[0025] As can be seen from the above, by establishing a proportional relationship that results in such sizes, it is possible to prevent the water column from becoming stuck. The diameter of the largest inscribed circle of the hole opening contour here may be the size of the widest point at the hole opening. The hole opening contours shown in Figures 8 and 9 are circular, and the diameter of the largest inscribed circle of the hole opening contour is the diameter of the hole opening. Moreover, when this proportional relationship is 1.5:1 or greater, it is possible to effectively achieve both the water discharge effect and the density and diameter of the water discharge holes.

[0026] 7, 8 and 9 are enlarged views showing the water-spouting panel. The minimum spacing size l between the openings of any two adjacent water-spouting holes 31, 31' located on the surface of the water-supply side 33 of the water-spouting panel is smaller than the diameter of the minimum inscribed circle of the outline of the openings of the corresponding two water-spouting holes 31, 31' located on the surface of the water-spouting side 32 of the water-spouting panel.

[0027] As can be seen from the above, by establishing such a proportional relationship, the area of ​​water facing the water supply side of the water discharge panel can be kept sufficiently small, reducing the resistance the water flow experiences when entering the discharge holes within the chamber and preventing the water flow from building up pressure within the chamber. The diameter of the smallest inscribed circle of the hole opening contour here may be the size of the narrowest part of the hole opening. The hole opening contours shown in Figures 7, 8, and 9 are circular, and the diameter of the smallest inscribed circle of the hole opening contour is the hole opening diameter. Moreover, when this proportional relationship is 0.5:1 or less, it is possible to effectively achieve a balance between the water discharge speed, the density of the discharge holes, and the hole diameter of the discharge holes.

[0028] 1 or 3, the device further includes a mesh 40. The mesh 40 is provided on the water supply side 33 of the water-spouting panel. The mesh 40 is installed with a gap between it and the water-spouting panel 30. The area of ​​a single mesh hole in the mesh 40 is smaller than the area of ​​the hole outline of the water-spouting hole 31 located on the surface of the water-spouting side 32 of the water-spouting panel.

[0029] As can be seen from the above description, the mesh can screen out relatively large impurities, preventing the impurities from blocking the water outlet hole, preventing the water outlet hole from discharging water, or affecting the angle of the water flow.

[0030] Furthermore, referring to Figures 5 and 6, the discharge side 12 of the jet hole is connected to the external space of the discharge configuration via an air intake 50 whose opening is located on the same side as the discharge panel 30. That is, the air intake 50 is located on the water discharge side of the water discharge panel 30, in other words, the air intake 50 and the water discharge side of the water discharge panel 30 are located on the same side.

[0031] As can be seen from the above description, this technical solution is applied to a water discharge structure with two independent water discharge passages, the additionally installed water discharge passage is connected to the external space of the water discharge structure, the water supply ports of the two water discharge passages are connected to each other, and the water supply ports of the two water discharge passages can be selectively connected to the jet holes on the jet panel by rotating them relative to the jet panel. This is because the area of ​​the jet holes is 0.04mm 2 ~0.3mm 2 When the water discharge panel is discharging water (water is passing through the corresponding water discharge passage), air can be drawn in through the additionally installed water discharge passage.

[0032] Furthermore, as shown in Figures 1 and 2, 3 and 4, the discharge side 12 of the jet hole is connected to the external space of the discharge structure via an air intake 50 whose opening is located in the side wall of the discharge structure.

[0033] As can be seen from the above description, the configuration of this technical solution is relatively simple. The communication distance between the discharge side of the jet holes and the external space of the discharge structure is extremely short. Air in the external space can easily reach the discharge side of the jet holes and mix with the jet. The technical solution shown in Figures 1 and 2 differs from the technical solution shown in Figures 3 and 4 in the following ways: The jet holes in the technical solution shown in Figures 1 and 2 are located on the side wall of the jet panel, and the outlet contour of the jet holes on the discharge side of the jet panel is strip-shaped, while the jet holes in the technical solution shown in Figures 3 and 4 are located on the bottom surface of the jet panel, and the outlet contour of the jet holes on the discharge side of the jet panel is circular.

[0034] Furthermore, as shown in Figures 1 to 6, the above technical solutions are all applicable to the configuration of a foaming device. In addition, the above technical solutions can also be applied to the configuration of a bath shower head in other application scenes not shown in the drawings.

[0035] As can be seen from the above description, when the water discharge configuration of this technical solution is applied to a small foaming device, it is particularly applicable to situations where it is necessary to limit water splashing, such as vegetable sinks and hand washing sinks.When the water discharge configuration of this technical solution is applied to a bath shower head, the water discharge from the bath shower head is softer, which can improve the user's bathing experience.

[0036] Another technical solution in the present invention is as follows.

[0037] The water discharge arrangement includes a water discharge panel. The water discharge panel 30 is provided with a plurality of water discharge holes 31. The opening area of ​​the water discharge holes 31 located on the surface of the water supply side 33 of the water discharge panel is larger than the opening area of ​​the water discharge holes 31 located on the surface of the water discharge side 32 of the water discharge panel. The minimum spacing size l between the openings of any two adjacent water discharge holes 31, 31' located on the surface of the water supply side 33 of the water discharge panel is smaller than the diameter of the smallest inscribed circle of the opening contour of the corresponding two water discharge holes 31, 31' located on the surface of the water discharge side 32 of the water discharge panel. The area of ​​a single water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel is 0.04 mm2 ~0.3mm 2 is.

[0038] The operating principle of this technical solution is as follows: Because the inlet area of ​​the outlet hole is larger than the outlet area, the inner wall of the outlet hole can be ensured to have a certain inclination. Furthermore, because the area contracts from the inlet side to the outlet side, the water flow can be ensured to be smoothly accelerated from the outlet hole. Furthermore, because the inlet side opening area of ​​the outlet hole is larger than the outlet side opening area, the separation between adjacent outlet holes can be ensured to be expanded from the inlet side to the outlet side. This ensures that the spacing between the outlet side openings of the outlet hole is sufficiently large, preventing adjacent water columns from sticking together. At the same time, the minimum spacing between the openings on the inlet side surface of the outlet panel of any two adjacent outlet holes is smaller than the diameter of the smallest inscribed circle of the opening contours of the openings on the outlet side surface of the outlet panel of the two corresponding outlet holes. The shape of the water discharge hole with this feature further makes the area of ​​water facing the water supply side of the water discharge panel sufficiently small, thereby reducing the resistance force that the water flow experiences when entering the water discharge hole from the water discharge panel.

[0039] As can be seen from the above description, the above technical solution can ensure that the water flow passes through the spout panel smoothly and is ejected outward, which avoids the problem of pressure building up in the water flow when water is supplied to the chamber upstream of the spout panel, causing the water flow to easily overflow other gaps or passages in the structure.

[0040] Furthermore, as shown in Figures 4 and 6, the above technical solutions are all attached to the spouting side of the foaming device. In addition, in other application scenarios not shown in the drawings, the above technical solutions are also applied to bath shower heads and used as the spouting panel of the bath shower head.

[0041] Referring to Figures 1, 2 and 7, a first embodiment of the present invention is as follows.

That is, net 40 is provided on water supply side 33 of the water-discharge panel, and covers the entire water supply side 33 of the water-discharge panel.

The area of ​​a single mesh hole in the net 40 is smaller than the area of ​​the hole contour of the water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel.

[0046] The opening area of ​​a single water discharge hole 31 located on the surface of the water supply side 33 of the water discharge panel is larger than the opening area of ​​a single water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel.

Moreover, the minimum spacing size l between the hole contours of any two adjacent water discharge holes 31, 31' located on the surface of the water supply side 33 of the water discharge panel is smaller than the diameter of the minimum inscribed circle of the hole contours of the two adjacent water discharge holes 31, 31' located on the surface of the water discharge side 32 of the water discharge panel.

[0048] Referring to Figures 3, 4 and 8, a second embodiment of the present invention is as follows.

[0049] The difference between this embodiment and the first embodiment is as follows: The critical flow holes 11 are provided on the bottom surface of the critical flow panel 10, and the contour of the opening of the critical flow hole on the water discharge side 12 is circular. The area of ​​a single water discharge hole 31 located on the surface of the water discharge side 32 of the water discharge panel is 0.13 mm 2The sum of the opening areas of all the water discharge holes 31 located on the surface of the water discharge side 32 of the water discharge panel is 2.5 times the sum of the opening areas of all the jet holes 11 located on the surface of the water discharge side 13 of the jet panel. Not all of the water discharge holes 31 have the same opening size located on the surface of the water supply side 33 of the water discharge panel. The openings located on the surface of the water supply side 33 of the water discharge panel are installed so that they are aligned.

[0050] Referring to Figures 5, 6 and 9, a third embodiment of the present invention is as follows.

[0051] The difference between this embodiment and the above two embodiments is as follows: This embodiment is applied to a foaming device with multiple water outlets, and the jet holes 11 are provided on the bottom surface of the jet panel 10, and the outlet contour of the jet holes on the outlet side 12 of the jet panel is strip-shaped.
