Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom, in particular to a water outlet device, faucet and shower head. BACKGROUND

[0002] In order to enrich the water outlet function, the existing bathroom products adopt two water outlet modes. One is to distribute different nozzles on the water outlet plate to discharge different water flowers. Therefore, at any moment, the nozzles for generating other water flowers will be in a non-discharging state while the nozzles for generating a certain water flower are discharging. However, this mode will also cause the long-term unused nozzles to be blocked, thereby affecting normal use. The other mode is to realize different water flowers by interfering with the water flow. Referring to the patents disclosed in publication numbers CN111263665A, CN112705370A and CN114160323A, each nozzle has two water inlet channels. Each water inlet channel can supply water flow to the discharge chamber in the nozzle at different angles. By adjusting the flow rate of the water flow of the two water inlet channels, the two water flows are mixed into one water flow in the discharge chamber and discharged outward. The water flow entering the mixing chamber at different angles can form different forms of water flowers by adjusting the flow rate ratio. However, the two water inlet channels at different angles will make the shape of the nozzle more complex, thereby causing difficulty in developing the mold for injection molding of the water outlet plate. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a water outlet device that simplifies the water outlet plate while meeting the diversity of water outlet functions.

[0004] To solve the above technical problems, the first technical solution adopted by the present application is:

[0005] A water outlet device, comprising a water guide plate, a water outlet plate, a water inlet channel and a valve;

[0006] The water guide plate is provided with a first drainage hole;

[0007] The water outlet plate is provided with a discharge chamber, and the water inlet end of the discharge chamber is provided with a surrounding wall;

[0008] The water guide plate and the water outlet plate have a shunt chamber therebetween;

[0009] The shunt chamber is communicated with the discharge chamber through the water inlet channel, and the projection of the outlet of the first drainage hole in the axial direction of the water outlet plate towards the direction of the water outlet plate is at least partially located in the water inlet channel and not located in the discharge chamber;

[0010] The valve is located upstream of the water guide plate and the water outlet plate, and the valve is used to distribute the fluid to enter the discharge chamber from the water inlet channel after passing through the first drainage hole and / or the shunt chamber.

[0011] To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is as follows:

[0012] A faucet includes a faucet body and a water outlet device disposed at the water outlet end of the faucet body, wherein the water outlet device is the water outlet device described in the first technical solution above.

[0013] To solve the above-mentioned technical problems, the third technical solution adopted by the present invention is as follows:

[0014] A shower head includes a shower head body and a water outlet device disposed at the water outlet end of the shower head body, wherein the water outlet device is the water outlet device described in the first technical solution above.

[0015] The beneficial effects of this invention are as follows: An inlet channel is provided that can be connected to both the first drainage hole and the diversion chamber. During the formation of water splashes, most of the fluid is distributed to the first drainage hole or the diversion chamber via a valve and then enters the discharge chamber through the inlet channel. Due to the guiding effect of the inlet channel, the fluid flows in different directions into the discharge chamber, thus producing two different water splashes. Alternatively, the fluid is divided by a valve into two parts: one part enters the inlet channel through the first drainage hole, and the other part enters the inlet channel through the diversion chamber. The two fluids with different flow directions interact in the inlet channel and then form specific water splashes through the discharge chamber before being discharged from the outlet plate. Furthermore, by controlling the flow rate of the fluid flowing into the first drainage hole and the diversion chamber via a valve, the interaction effect of the two fluids can be changed, thereby achieving the spraying of different water splashes.

[0035] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] Please refer to Figures 1 to 10As shown, a water outlet structure includes a water guide plate 2, an outlet plate 3, an inlet channel 4, and a valve 1. The water guide plate 2 is provided with a first drainage hole 21. The outlet plate 3 is provided with a discharge chamber 31, and the inlet end of the discharge chamber 31 is provided with a surrounding wall 32. A diversion chamber 5 is provided between the water guide plate 2 and the outlet plate 3. The diversion chamber 5 is connected to the discharge chamber 31 through the inlet channel 4. The projection of the outlet of the first drainage hole 21 toward the outlet plate 3 in the axial direction of the outlet plate 3 is at least partially located in the inlet channel 4 and not located in the discharge chamber 31. The valve 1 is located upstream of the water guide plate 2 and the outlet plate 3. The valve 1 is used to distribute the fluid to enter the discharge chamber 31 from the inlet channel 4 after passing through the first drainage hole 21 and / or the diversion chamber 5.

[0037] Working principle: During the formation of water splashes, most of the fluid is distributed to the first drainage hole 21 or the diversion chamber 5 through valve 1 and then enters the discharge chamber 31 through the water inlet channel 4. Due to the guiding effect of the water inlet channel 4, the fluid flows in different directions into the discharge chamber 31, thus producing two different water splashes. Alternatively, the fluid is divided by valve 1 into two parts: one part enters the water inlet channel 4 through the first drainage hole 21, and the other part enters the water inlet channel 4 through the diversion chamber 5. The two fluids with different flow directions interact in the water inlet channel 4 and then form specific water splashes through the discharge chamber 31 before being discharged from the water outlet plate 3. By controlling the flow rate of the fluid flowing into the first drainage hole 21 and the flow rate of the diversion chamber 5 through valve 1, the interaction effect of the two fluids can be changed, thereby achieving the spraying of different water splashes.

[0038] In addition, it should be noted that when the outlet of the first drainage hole 21 is basically opened in the direction of the water outlet plate 3, its projection in the water inlet channel 4 is planar; however, in some special structures, the outlet direction of the first drainage hole 21 can also be perpendicular to the axial direction of the water outlet plate 3. In this case, the projection of the outlet of the first drainage hole 21 in the direction of the water inlet channel 4 in the axial direction of the water outlet plate 3 is linear.

[0039] In the first alternative implementation, please refer to Figure 4 or Figure 5 or Figure 6 As shown, the water inlet channel 4 penetrates the enclosure wall 32, so that the diversion chamber 5 is connected to the discharge chamber 31 through the water inlet channel 4.

[0040] In the second alternative implementation, please refer to Figure 7 As shown, the water inlet channel 4 bypasses the enclosure wall 32 and is connected to the discharge chamber 31 by being recessed on the side of the water outlet plate 3 facing the water guide plate 2, so that the diversion chamber 5 is connected to the discharge chamber 31 through the water inlet channel 4.

[0041] In other alternative embodiments not shown in the accompanying drawings, the water inlet channel 4 can also be constructed by partially penetrating the enclosure wall 32 and partially recessed into the water outlet plate 3. Such an embodiment can also enable the diversion chamber 5 to communicate with the discharge chamber 31 through the water inlet channel 4.

[0042] In the above different alternative embodiments, the enclosure 32 can be as follows: Figures 4 to 6 As shown, it is integrated with the water outlet plate 3, or it can be set as follows: Figure 7 The water guide plate 2 and / or the outlet plate 3 are shown as being set independently and fixedly connected to it. In other optional embodiments not shown in the attached drawings, it can also be set integrally with the water guide plate 2.

[0043] Regarding how valve 1 distributes fluid into the first drain hole 21 and / or the diversion chamber 5, in a third alternative embodiment, please refer to... Figure 1 , Figure 2 and Figure 11 As shown, the water guide plate 2 is provided with a second drainage hole 22, and the outlet of the second drainage hole 22 faces into the diversion cavity 5 in the axial direction of the water outlet plate 3.

[0044] The valve 1 includes a valve body 11 and a valve core 12. The valve body 11 has a first diversion orifice 111 and a second diversion orifice 112. The first diversion orifice 111 supplies fluid to a first guide orifice 21, and the second diversion orifice 112 supplies fluid to a second guide orifice 22. The valve core 12 is movably mounted on the valve body 11 and controls the flow rate of fluid through the first diversion orifice 111 and the second diversion orifice 112. By manipulating the movement of the valve core 12 on the valve body 11, the opening degree of the valve core 12 to the first diversion orifice 111 and the second diversion orifice 112 can be changed, thereby controlling the flow rate of fluid through the first diversion orifice 111 and the second diversion orifice 112. Preferably, when the flow rate of fluid through the first diversion orifice 111 decreases, the flow rate of fluid through the second guide orifice 22 increases; conversely, when the flow rate of fluid through the first diversion orifice 111 increases, the flow rate of fluid through the second guide orifice 22 decreases.

[0045] Since the fluid, after being distributed by valve 1, enters the discharge chamber 31 through the inlet channel 4, the diversion point of valve 1 can adopt a partially sealed or even unsealed structure. This allows the device to allow a small portion of the fluid to leak into the inlet channel 4 through the first drain hole 21 (or into the inlet channel 4 through the diversion chamber 5) at any given time. This will not significantly affect the final formation of the pre-set water droplets after the fluid is discharged from the discharge chamber 31. The device has low sealing requirements for the fluid flow path and high tolerance for leakage. This characteristic helps reduce the number of sealing rings used in the valve structure, reduces the friction that needs to be overcome during valve operation, and improves the operating feel.

[0046] It is worth noting that the valve 1 required by this device can also be other valves in the art used to control different output flow rates, and has good adaptability.

[0047] As disclosed in CN111263665A, "Improvements to or relating to nozzles," paragraphs [0120 to 0123] of its specification state: The valve is a sliding valve, but it can also be a rotary valve, or a similar valve, to separate and change the fluid supply between a first fluid supply and a second fluid supply as described below. The sliding valve body has at least one seal facing downwards, and preferably also has a seal at the upper end to ensure watertightness while allowing the valve body to slide easily. These seals are lip seals. The controller, seals, and valve body are contained in a housing, which can slide into and be held therein individually or in a form. This allows for easy assembly, replacement, and maintenance. The housing and its components can slide in from either end of the body as needed. A cover covers the end of the body away from the connector. In a preferred form, the fluid separator does not have a seal against the exterior of the valve body. Instead, the seal defines a sealing volume to prevent fluid from leaving the volume. Because there is no seal between the fluid separator and the valve body, the fluid moves freely between the first fluid supply and the second fluid supply even when the slider and the valve body are at their two ends of movement.

[0048] For example, the "Water Dispensing Device with Different Splashes from the Same Mouth" disclosed in announcement number CN112705370A describes in paragraph

[0070] that the top surface of the distributor is provided with water dispensing holes corresponding to each water dispensing chamber. The control mechanism includes a water dispensing plate, the bottom surface of which is connected to the top surface of the distributor. The water dispensing plate rotates and connects to the distributor so as to control whether the water outlet chamber and the water dispensing hole are connected and the flow rate of the connection. The water dispensing plate has a water dispensing shaft, which extends out of the fixed seat in a sealed rotation. The water dispensing shaft can drive the water dispensing plate to rotate, and can control whether each water dispensing hole is connected to the water dispensing chamber and the connection area of ​​the connection to the water outlet chamber (a larger connection area results in a larger flow rate, and a smaller connection area results in a smaller flow rate).

[0049] For example, in the "Water Outlet Structure with Different Splashes from the Same Mouth and Water Outlet Device Using the Structure" disclosed in CN114160323A, paragraph

[0042] of the specification describes that a first water outlet and a second water outlet are respectively provided in the water distribution component. The first water outlet is connected to the first water inlet, and the second water outlet is connected to the second water inlet. There is a partition between the first water outlet and the second water outlet, which separates the first water outlet and the second water outlet. The first water outlet is located inside the partition, and the second water outlet is located outside the partition. When water enters the first water outlet, the water will not overflow to the position of the second water outlet due to the obstruction of the partition. Similarly, when water enters the second water outlet, the water will not overflow to the position of the first water outlet due to the obstruction of the partition, so that the water distribution lines of the two do not interfere with each other and are relatively independent.

[0050] As disclosed in the "Water Outlet Device and Shower Head" with announcement number CN114160321A, paragraph

[0039] of its instruction manual describes that the valve core has a valve plate with an arc surface. The valve core can be rotatably connected in the control cavity so that the valve plate is rotatably connected in the control cavity and rotatably adapted to abut against the arc surface of the inner cavity wall. The valve plate can steplessly control the blocked area of ​​the two water outlets to steplessly adjust the flow ratio of the two water channels and stop the water flow. The specification states in paragraph

[0040] that the valve core includes two spaced-apart turntables and a drive shaft. The valve plate is fixed between the two turntables, which are rotatably connected in the control chamber. The positions of the two water outlets correspond to the interval between the two turntables. The drive shaft is fixed on the turntable located on the outer side. The circumferential wall of the turntable is recessed with an arc groove, and the inner wall of the control chamber is protruded with a limiting protrusion. The limiting protrusion is located in the arc groove to limit the rotation trajectory of the valve core through the cooperation of the arc groove and the limiting protrusion, so as to control the water splash change and stop the water flow.

[0051] In the fourth alternative implementation, please refer to Figures 8 to 10As shown, the valve 1 has a first diversion hole 111 and a second diversion hole 112. The first diversion hole 111 supplies fluid towards the first drainage hole 21, and the second diversion hole 112 supplies fluid towards the diversion chamber 5. By controlling the fluid flow rates into the first diversion hole 111 and the second diversion hole 112, the fluid flow rates into the first drainage hole 21 and the diversion chamber 5 can be achieved, and thus the spraying of different water flowers can be realized. In this embodiment, other parts of the valve 1 can adopt the solutions of the similar publication numbers CN201026468Y or CN201949936U to distribute the fluid flow rates into the first diversion hole 111 and the second diversion hole 112.

[0052] For a part of the fluid entering the water inlet channel 4 through the first drainage hole 21 and another part of the fluid entering the water inlet channel 4 through the diversion chamber 5, the two fluids with different flow directions interact in the water inlet channel 4, and there are the following three situations:

[0053] In the fifth optional embodiment, please refer to Figure 4 As shown, the direction in which the first drainage hole 21 drains fluid towards the water inlet channel 4 is perpendicular to the direction in which the diversion chamber 5 drains fluid towards the water inlet channel 4. The fluid introduced into the water inlet channel 4 through the first drainage hole 21 interferes with the fluid introduced into the water inlet channel 4 by the diversion chamber 5, which can play a role in reducing the fluid flow rate, so that a relatively gentle water flow is discharged from the discharge chamber 31.

[0054] In the sixth optional embodiment, please refer to Figure 5 As shown, the direction in which the first drainage hole 21 drains fluid towards the water inlet channel 4 and the direction in which the diversion chamber 5 drains fluid towards the water inlet channel 4 form an obtuse angle C. Preferably, 90° < C ≤ 120°. The fluid introduced into the water inlet channel 4 through the first drainage hole 21 impacts the fluid introduced into the water inlet channel 4 by the diversion chamber 5, which can play a significant role in reducing the fluid flow rate, so that a more gentle water flow is discharged from the discharge chamber 31, especially suitable for use in high water pressure areas.

[0055] In the seventh optional embodiment, please refer to Figure 6 As shown, the direction in which the first drainage hole 21 drains fluid towards the water inlet channel 4 and the direction in which the diversion chamber 5 drains fluid towards the water inlet channel 4 form an acute angle D. Preferably, 70° ≤ D < 90°. The fluid introduced into the water inlet channel 4 through the first drainage hole 21 mixes with the fluid introduced into the water inlet channel 4 by the diversion chamber 5, which can play a role in accelerating the fluid flow, so that a water flow with a stronger impact force is discharged from the discharge chamber 31, especially suitable for use in low water pressure areas.

[0056] It should be noted that the above fifth to seventh optional embodiments can be carried out in the above first optional embodiment or in the above second optional embodiment.

[0057] In the eighth optional embodiment, the projection of the outlet of the first drainage hole 21 toward the water outlet plate 3 along the axial direction is entirely located within the water inlet channel 4. This solution allows all the fluid to enter the water inlet channel 4 after passing through the first drainage hole 21, minimizing fluid power consumption and is a preferred implementation.

[0058] In the ninth optional embodiment, the projection of the outlet of the first drainage hole 21 toward the water outlet plate 3 in the axial direction is located at least two of the following: inside the water inlet channel 4, inside the diversion cavity 5, and on the end face of the enclosure wall 32. Although this solution allows only a portion of the fluid to enter the water inlet channel 4 after passing through the first drainage hole 21, resulting in some loss of fluid power, this solution has lower requirements for the precision of the parts themselves and the fit between the parts, which helps to reduce the manufacturing cost of the parts and improve assembly efficiency.

[0059] In one implementation, please refer to Figure 11 As shown, the water guide plate 2 has a groove 23 on its end face opposite to the water outlet plate 3, and the first drainage hole 21 is located in the groove 23. Since the fluid needs to enter the water inlet channel 4 from the first drainage hole 21 in as single a direction as possible, the fluid gathers in the groove 23 before entering the first drainage hole 21. This avoids the flow direction of the fluid discharged from the first drainage hole 21 into the water inlet channel 4 from the fluid impacting each other from multiple directions.

[0060] Preferably, the inlet of the first drainage hole 21 is close to the side wall of the groove 23, which can further eliminate the influence of multi-directional fluid flow in the groove 23 on the flow direction of the fluid discharged from the first drainage hole 21.

[0061] In the tenth optional embodiment, the water inlet end of the discharge chamber 31 is a circular hole, and the flow direction line of the water inlet channel 4 passes through the center of the water inlet end of the discharge chamber 31. Taking the fluid flow rate from the diversion chamber 5 into the water inlet channel 4 as greater than the fluid flow rate from the first drainage hole 21 into the water inlet channel 4 as an example, after the two fluids interact in the water inlet channel 4, they flow directly towards the center of the water inlet end of the discharge chamber 31 along the water inlet channel 4, and then generate columnar shower water under the action of the inner wall of the water inlet end of the discharge chamber 31.

[0062] In the eleventh optional embodiment, the water inlet end of the discharge chamber 31 is a circular hole, and the flow direction line of the water inlet channel 4 is the secant line of the water inlet end of the discharge chamber 31, and the flow direction line of the water inlet channel 4 does not pass through the center of the water inlet end of the discharge chamber 31. Taking the fluid flow rate from the diversion chamber 5 into the water inlet channel 4 as greater than the fluid flow rate from the first drainage hole 21 into the water inlet channel 4 as an example, after the two fluids interact in the water inlet channel 4, they flow along the secant line of the water inlet channel 4 toward the water inlet end of the discharge chamber 31. The closer the fluid flows to the center of the water inlet end of the discharge chamber 31, the more it tends to produce shower water under the action of the inner wall of the water inlet end of the discharge chamber 31. The closer the fluid flows to the tangent direction of the water inlet end of the discharge chamber 31, the more it tends to produce large-particle water (e.g., water droplet diameter of about 0.6 mm) under the action of the inner wall of the water inlet end of the discharge chamber 31.

[0063] In the twelfth optional embodiment, the inlet end of the discharge chamber 31 is a circular hole, and the flow direction line of the inlet channel 4 is tangent to the inlet end of the discharge chamber 31. Taking the fluid flow rate from the diversion chamber 5 into the inlet channel 4 as greater than the fluid flow rate from the first drainage hole 21 into the inlet channel 4 as an example, after the two fluids interact in the inlet channel 4, they flow along the tangential direction of the inlet channel 4 toward the inlet end of the discharge chamber 31, and under the action of the inner wall of the inlet end of the discharge chamber 31, small particulate water particles (e.g., water droplet diameter of about 0.3 mm) are generated.

[0064] According to the tenth to twelfth optional embodiments described above, the procedure can be performed in either the first optional embodiment or the second optional embodiment described above. Please refer to... Figure 12 and Figure 13 As shown, the water inlet channel 4 forms a first flow channel 41 and a second flow channel 42 through a partition. The first flow channel 41 and the second flow channel 42 are connected to the discharge chamber 31 through the outlet of the water inlet channel 4. The second flow channel 42 is not connected to the diversion chamber 5. The partition extends toward the water inlet end of the discharge chamber 31 and has a gap with the edge of the water inlet end of the discharge chamber 31. The projection of the outlet of the first drainage hole 21 is entirely located in the water inlet channel 4 and falls at the gap. The diversion chamber 5 is connected to the discharge chamber 31 through the first flow channel 41. The first drainage hole 21 is connected to the discharge chamber 31 through the first flow channel 41 and the second flow channel 42. This embodiment achieves a second distribution of fluid by dividing the inlet channel 4. The fluid that enters the inlet channel 4 through the first drainage hole 21 is distributed to enter the first flow channel 41 and the second flow channel 42 respectively. This allows the fluid entering the first flow channel 41 to interact with the fluid entering the first flow channel 41 from the diversion chamber 5. The fluid entering the second flow channel 42 does not participate in the above interaction and directly enters the discharge chamber 31. This can improve the intensity of the discharged water pressure, and is especially suitable for use in areas with low water pressure.

[0065] According to the tenth to twelfth optional embodiments described above, the procedure can be carried out in either the first optional embodiment or the second optional embodiment. The diversion cavity 5 is connected to the discharge cavity 31 via the first flow channel 41 and the second flow channel 42, and the communication area between the diversion cavity 5 and the first flow channel 41 is more than twice the communication area with the second flow channel 42; the first drainage hole 21 is connected to the discharge cavity 31 via the first flow channel 41 and the second flow channel 42. The fluid entering the inlet channel 4 through the first drainage hole 21 will enter the first flow channel 41 and the second flow channel 42 respectively. The fluid entering the inlet channel 4 through the diversion cavity 5 will enter the first flow channel 41 and the second flow channel 42 respectively. Due to the difference in the communication area between the diversion cavity 5 and the first flow channel 41 and the second flow channel 42, the fluid in the first flow channel 41 interacts and produces a significant interference effect, while the fluid in the second flow channel 42 interacts and produces a weak interference effect. The two streams of fluid will interfere with each other again before entering the discharge cavity 31, and finally spray water from the discharge cavity 31, which is different from other embodiments.

[0066] Preferably, the bottom surfaces of the first flow channel 41 and the second flow channel 42 have a height difference along the axial direction of the water outlet plate 3, and the height difference is formed by the bottom surfaces of the flow channels sloping downwards toward the discharge chamber 31. The bottom surface of the first flow channel 41 can be higher than the bottom surface of the second flow channel 42, or it can be lower. The flow channel with a lower height difference will allow the water to enter the discharge chamber 31 at a steeper angle, thus producing an acceleration effect. The direction of the height difference along the circumference of the discharge chamber being in the same direction as or opposite to the entry direction of the other flow channel will also cause acceleration or deceleration effects, resulting in different effects in the final discharged water spray.

[0067] In one embodiment, the inlet and outlet ends of the discharge chamber 31 are both circular holes, and the axis of the outlet end of the discharge chamber 31 does not coincide with the axis of the inlet end of the discharge chamber 31. This can change the total fluid discharge area of ​​all discharge chambers 31 on the water outlet plate 3.

[0068] In the thirteenth alternative implementation, please refer to Figure 3 As shown, the center of the outlet end of the discharge chamber 31 is closer to the edge of the outlet plate 3 than the center of the inlet end of the discharge chamber 31. The water outlet direction of the discharge chamber 31 forms an angle E with the surface of the outlet plate 3. Preferably, 80° ≤ E ≤ 90°. Having the center of the outlet end of the discharge chamber 31 closer to the edge of the outlet plate 3 than the center of the inlet end of the discharge chamber 31 increases the fluid discharge area of ​​the outlet plate 3, thereby improving the user experience.

[0069] Conversely, if the center of the water outlet end of the discharge chamber 31 is closer to the center of the water outlet plate 3 than the center of the water inlet end of the discharge chamber 31, i.e., 90° < E ≤ 110°, the fluid discharge area of ​​the water outlet plate 3 can be reduced, allowing all the water droplets to converge at the center of the water outlet plate 3 to achieve a stronger rinsing and massage effect.

[0070] A faucet includes a faucet body and a water outlet device disposed at the water outlet end of the faucet body, wherein the water outlet device is the water outlet device described in the above-mentioned solution. The faucet can be a pull-out faucet, and the water outlet device in the above-mentioned solution is disposed in the pull-out structure.

[0071] A shower head includes a shower head body and a water outlet device disposed at the water outlet end of the shower head body, wherein the water outlet device is the water outlet device in the above-described solution. The shower head can be a handheld shower head, an overhead shower head, or a side shower head.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
