Description

A water outlet device, faucet and shower head Technical Field This invention relates to the field of bathroom technology, and in particular to a water outlet device, faucet and shower head. Background Technology Existing bathroom products employ two water discharge methods to enrich their water output functionality. One method involves distributing different nozzles on the water outlet plate to emit different water sprays. Therefore, at any given time, if one spray is being emitted, the nozzles used to generate other sprays will be in a non-discharge state. However, this method can cause nozzles that are not used for extended periods to become clogged, affecting normal use. The other method uses water flow interference to achieve different sprays, as disclosed in patents CN111263665A, CN112705370A, and CN114160323A. In this design, each nozzle has two inlet channels, each capable of supplying water to the outlet chamber at different angles. By adjusting the flow rate of the two inlet channels, the two water streams are mixed into a single stream before being discharged. The different spray patterns can be created by adjusting the flow rate ratio of the two streams entering the mixing chamber at different angles. However, having two inlet channels at different angles results in a more complex nozzle shape, making mold development for the water outlet plate injection molding process more difficult. Technical issues The technical problem to be solved by the invention is to provide a water outlet device that simplifies the water outlet plate while satisfying the diversity of water outlet functions. Technical solutions To solve the above-mentioned technical problems, the first technical solution adopted by the present invention is as follows: A water outlet device includes a water guide plate, a water outlet plate, a water inlet channel, and a valve; The water guide plate is provided with a first drainage hole; 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; A flow-diverting cavity is provided between the water guide plate and the water outlet plate; The diversion chamber is connected to the discharge chamber via the water inlet channel. The projection of the outlet of the first drainage hole toward the water outlet plate in the axial direction of the water outlet plate is at least partially located in the water inlet channel and not located in the discharge chamber. The valve is located upstream of the guide plate and the outlet plate. The valve is used to distribute the fluid to the discharge chamber after passing through the first diversion hole and / or the diversion chamber. To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is as follows: 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. To solve the above-mentioned technical problems, the third technical solution adopted by the present invention is as follows: 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. Beneficial effects 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.

Embodiments of the present invention 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. Referring to Figures 1 to 10, 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 via 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 within the inlet channel 4 and not within 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. 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. 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. In a first optional embodiment, as shown in Figure 4, 5, or 6, the water inlet channel 4 penetrates the enclosure wall 32, so that the diversion chamber 5 is connected to the discharge chamber 31 via the water inlet channel 4. In a second alternative embodiment, as shown in Figure 7, 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 guide plate 2, so that the diversion chamber 5 is connected to the discharge chamber 31 via the water inlet channel 4. 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. In the above different optional embodiments, the enclosure 32 can be integrally set with the water outlet plate 3 as shown in Figures 4 to 6, or it can be set independently and fixedly connected to the water guide plate 2 and / or the water outlet plate 3 as shown in Figure 7. In other optional embodiments not shown in the figures, it can also be integrally set with the water guide plate 2. Regarding how valve 1 distributes fluid into the first drainage hole 21 and / or the diversion chamber 5, in a third alternative embodiment, as shown in Figures 1, 2 and 11, 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 chamber 5 in the axial direction of the water outlet plate 3. 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. 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 diversion chamber 5 and then into the inlet channel 4 at any given time, even if valve 1 is actively adjusted to completely distribute the fluid to the inlet channel 4 via the first drain hole 21 (or to completely distribute the fluid to the inlet channel 4 via the diversion chamber 5). This will not significantly affect the final formation of the pre-set water droplets after the fluid is discharged from the discharge chamber 31. This device has low sealing requirements for the fluid flow path and high tolerance for leakage. This characteristic helps to reduce the number of sealing rings used in the valve structure, reduce the friction that needs to be overcome during valve operation, and improve the operating feel. 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. 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.

[0070] The section describes a distribution device with corresponding water distribution holes on its top surface for each water distribution chamber. The control mechanism includes a water distribution plate, the bottom of which is connected to the top surface of the distribution device. The water distribution plate rotates to connect the distribution device, thereby controlling whether the outlet chamber and the water distribution holes are connected and the flow rate. The water distribution plate has a water distribution shaft, which extends out of the fixed seat in a sealed manner. The water distribution shaft can drive the water distribution plate to rotate, thereby controlling whether each water distribution hole is connected to the water distribution chamber and the connection area of ​​the outlet chamber (a larger connection area results in a larger flow rate, and a smaller connection area results in a smaller flow rate). For example, the water outlet structure with different water sprays from the same spout and the water outlet device using the same structure disclosed in announcement number CN114160323A, its specification section...

[0042] The section describes the installation of a first water distribution hole and a second water distribution hole in the water distribution assembly. The first water distribution hole is connected to the first water inlet hole, and the second water distribution hole is connected to the second water inlet hole. A partition plate separates the first water distribution hole and the second water distribution hole. The first water distribution hole is located inside the partition plate, and the second water distribution hole is located outside the partition plate. When water enters the first water distribution hole, the water will not overflow to the position of the second water distribution hole due to the obstruction of the partition plate. Similarly, when water enters the second water distribution hole, the water will not overflow to the position of the first water distribution hole due to the obstruction of the partition plate. This ensures that the water distribution lines of the two water distribution holes do not interfere with each other and are relatively independent. For example, the "Water Outlet Device and Shower Head" disclosed in announcement number CN114160321A, its instruction manual...

[0039] The description states that the valve core has a valve plate with an arc-shaped surface. The valve core is rotatably connected to the control chamber, allowing the valve plate to be rotatably connected to the control chamber and rotatably adapted to fit against the arc-shaped surface of the inner chamber wall. This allows for stepless control of the blocked area of ​​the two water outlets through the movement of the valve plate, thereby steplessly adjusting the flow ratio of the two water channels and stopping the flow. (See the instruction manual, page number...)

[0040] The section describes the valve core as including 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 to 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. In a fourth optional embodiment, referring to Figures 8 to 10, the valve 1 has a first diversion orifice 111 and a second diversion orifice 112. The first diversion orifice 111 supplies fluid toward the first guide orifice 21, and the second diversion orifice 112 supplies fluid toward the diversion chamber 5. By controlling the flow rate of the fluid entering the first diversion orifice 111 and the second diversion orifice 112, the flow rate of the fluid flowing into the first guide orifice 21 and the diversion chamber 5 can be controlled, thereby achieving different water spray patterns. In this embodiment, other parts of the valve 1 can use a scheme similar to those in publication numbers CN201026468Y or CN201949936 U to distribute the flow rate of the fluid entering the first diversion orifice 111 and the second diversion orifice 112. A portion of the fluid enters the inlet channel 4 through the first drainage hole 21, while another portion enters the inlet channel 4 through the diversion chamber 5. The two fluids with different flow directions interact in the inlet channel 4, resulting in the following three scenarios: In the fifth optional embodiment, as shown in Figure 4, the direction of the first drainage hole 21 toward the water inlet channel 4 is perpendicular to the direction of the diversion chamber 5 toward 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 through the diversion chamber 5, which can reduce the fluid flow rate, thereby allowing the discharge chamber 31 to discharge a gentler water flow. In a sixth optional embodiment, as shown in Figure 5, the direction of the first drainage hole 21 toward the water inlet channel 4 to drain the fluid forms an obtuse angle C with the direction of the diversion cavity 5 toward the water inlet channel 4 to drain the fluid. A preferred angle is 90°. <c≤120°。通过第一引流孔21引入进水通道4的流体对分流腔5引入进水通道4的流体进行对冲，能够起到显著降低流体流速的作用，从而使排放腔31排出更为柔和的水流，尤其适用于高水压地区的使用。In the seventh optional embodiment, as shown in Figure 6, the direction of the first drainage hole 21 toward the water inlet channel 4 and the direction of the diversion chamber 5 toward 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 through the diversion chamber 5, which can accelerate the fluid flow, thereby allowing the discharge chamber 31 to discharge a water flow with a strong impact force, which is especially suitable for use in low water pressure areas. It is worth noting that the fifth to seventh optional implementation methods described above can be implemented in the first optional implementation method described above, or in the second optional implementation method described above. 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. 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. In one embodiment, as shown in Figure 11, 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 unidirectional 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. 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. 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. 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 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 direction 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. 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 (e.g., water droplet diameter of about 0.3 mm) is generated. According to the tenth to twelfth optional embodiments described above, the process can be carried out in either the first optional embodiment or the second optional embodiment. Referring to Figures 12 and 13, the water inlet channel 4 forms a first flow channel 41 and a second flow channel 42 via a partition. The first flow channel 41 and the second flow channel 42 communicate with 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 towards 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 within the water inlet channel 4 and falls within this gap. The diversion chamber 5 communicates with the discharge chamber 31 via the first flow channel 41, and the first drainage hole 21 communicates with the discharge chamber 31 via 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. 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. 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. 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. In the thirteenth optional embodiment, referring to Figure 3, the center of the water outlet end of the discharge chamber 31 is closer to the edge of the water outlet plate 3 than the center of the water 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 water outlet plate 3. Preferably, 80° ≤ E ≤ 90°. Having the center of the water outlet end of the discharge chamber 31 closer to the edge of the water outlet plate 3 than the center of the water inlet end of the discharge chamber 31 increases the fluid discharge area of ​​the water outlet plate 3, thereby improving the user experience. 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. 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. 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. The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
