Description

Technical Field

[0001] This invention relates to a water outlet device, and more particularly to a water outlet device with a water spray switching mechanism. Background Technology

[0002] Remote switching (external system switching) is mainly used to enable function switching for overhead sprinklers installed at high heights that are difficult to reach. This addresses pain points such as the ball head easily wobbling during function switching and the varying height requirements for overhead sprinkler switching among people of different heights. There are two main solutions on the market:

[0003] 1. Handheld remote control of top spray function switching: The switching position is set on the handheld device. The water can be turned on and off by hand, which means that the water can be turned off when the handheld device is on and off, and vice versa. This technical solution can only control the on and off of the top spray and does not solve the problem of the multi-function switching of the top spray itself.

[0004] 2. Shower main control for multi-functional switching of overhead spray: The switching position is set at the bottom of the shower (shower main control). The multi-functional switching of the overhead spray is achieved by running pipes in the pipes. N functions require N internal pipes. The more functions there are, the larger the pipe diameter is required. In addition, running pipes in the pipes will affect the swing function of the overhead spray ball head. At the same time, the installation is complicated. Summary of the Invention

[0005] The main technical problem to be solved by the present invention is to provide a method and device for remotely switching the water flow of a water outlet device, which realizes remote water flow switching and has a simple structure and is easy to install.

[0006] To solve the above-mentioned technical problems, the present invention provides a method for remotely switching the water flow of a water outlet device, comprising the following steps:

[0007] 1) When water is supplied, the water flow causes the water distribution plate to move from the first position to the second position;

[0008] 2) The flow path of the water in the inlet seat changes, so that the water flow drives the water distribution plate to return to the first position;

[0009] During movement, the water distribution plate rotates at a certain angle by reversing its direction with the water inlet seat through a reversing component.

[0010] The present invention also provides a method for remotely switching the water flow of a water outlet device, comprising the following steps:

[0011] 1) When water is supplied, the water flow causes the water distribution plate to move from the first position to the second position;

[0012] 2) The direction of the force exerted by the water flow on the water distribution plate changes, thereby driving the water distribution plate to reset from the second position to the first position;

[0013] During movement, the water distribution plate rotates at a certain angle by reversing its direction with the water inlet seat through a reversing component.

[0014] In a preferred embodiment: the water distribution plate rotates when it moves from the first position to the second position or from the second position to the first position; or, the water distribution plate rotates when it moves from the first position to the second position and when it moves from the second position to the first position, respectively.

[0015] In a preferred embodiment: when the water distribution plate moves from the first position to the second position, the water distribution plate rotates by a first angle A through the first reversing member;

[0016] When the water distribution plate moves from the second position to the first position, the water distribution plate rotates by a second angle B through the second reversing member.

[0017] In a preferred embodiment, the rotation directions of angle A and angle B are the same.

[0018] In a preferred embodiment: when the water distribution plate is in the first position, the first water passage in the water outlet device is opened, and the water flow acts on the bottom of the water distribution plate to drive the water distribution plate to rise; when the water distribution plate is in the second position, the second water passage in the water outlet device is opened, and the water flow acts on the top of the water distribution plate to drive the water distribution plate to fall.

[0019] The present invention also provides a structure for remote switching of water flow in a water outlet device, comprising: a water inlet base, a water distribution plate, and a water outlet body;

[0020] The water inlet seat has a first flow channel, which is connected to the first water outlet of the water distribution plate; the water inlet seat is also equipped with a valve core for opening or closing the first flow channel;

[0021] When water is introduced into the water inlet seat, the water flow acts on the water distribution plate through the first flow channel to drive the water distribution plate to move from the first position to the second position.

[0022] When the water distribution plate moves to the second position, the valve core closes the first flow channel under water pressure, so that the water distribution plate returns to the first position from the second position;

[0023] During movement, the water distribution plate rotates at a certain angle by switching with the water inlet seat through a reversing component, so that the water distribution hole of the water distribution plate is connected with different water outlet holes on the water outlet body.

[0024] In a preferred embodiment: when the water distribution plate moves from the first position to the second position, the water distribution plate rotates by a first angle A through a first reversing member and a water inlet seat in a reversing engagement.

The first outlet is lower than the lower surface of the water distribution plate along the water flow direction, and the second outlet is higher than the upper surface of the water distribution plate along the water flow direction.

[0030] When the water distribution plate is in the second position, the valve core opens the second flow channel and closes the first flow channel.

[0031] In a preferred embodiment: the water distribution plate has a damping hole connecting the first water outlet and the second water outlet; when the first flow channel is open, the water flows through the damping hole into the second flow channel.

[0032] In a preferred embodiment: the valve core is fitted with an elastic element, and when the second flow channel is opened, the elastic element is squeezed by the valve core and accumulates elastic restoring force.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0050] This embodiment provides a method for remotely switching the water flow of a water outlet device, including the following steps:

[0051] 1) When water is supplied, the water flow causes the water distribution plate to move from the first position to the second position;

[0052] 2) The flow path of the water in the inlet seat changes, so that the water flow drives the water distribution plate to return to the first position;

[0053] The water distribution plate rotates at a certain angle during movement via a reversing component.

[0054] The change in flow path here can be achieved by the water flowing from one channel to another, thus changing the direction of the force exerted by the water flow on the distributor plate. Alternatively, the original channel can be closed directly, causing the force exerted by the water flow on the distributor plate to disappear, thereby achieving the purpose of resetting the distributor plate.

[0055] The aforementioned remote switching method achieves water splash switching by rotating the water distribution plate driven by water flow. In this way, the water distribution plate can still be set inside the water outlet device, avoiding the problem of increased pipe diameter caused by placing the water splash switching mechanism on the main control of the shower in the existing technology.

[0056] The rotation of the water distribution plate can occur when the plate moves from the first position to the second position, or when it moves from the second position to the first position; alternatively, the plate can rotate both when moving from the first position to the second position and when moving from the second position to the first position. As long as the water distribution plate rotates during its movement, the water flowing through its distribution port enters different through-holes in the outlet body, thus creating different water spray patterns.

[0057] To achieve the switching method described above, the following switching structure is adopted in this embodiment:

[0058] refer to Figures 1-9 This embodiment provides a structure for remote switching of water flow in a water outlet device, including: a water inlet seat 13, a water distribution plate 2, and a water outlet body 14; the water inlet seat 13 is disposed inside the water outlet device 1.

[0059] The water inlet seat 13 has a first flow channel 11, which is connected to the first water outlet 111 of the water distribution plate 2; the water inlet seat 13 is also equipped with a valve core 12 for opening or closing the first flow channel 11.

[0060] When water is supplied to the inlet seat 13, the water flow acts on the water distribution plate 2 through the first flow channel 11, causing the water distribution plate 2 to move from the first position to the second position. The force of the water flow acting on the water distribution plate 2 through the first flow channel 11 is upward. When the water distribution plate 2 moves to the second position, the valve core 12 closes the first flow channel 11 under the action of water pressure, so that the water distribution plate 2 returns to the first position from the second position.

[0061] During the movement, the water distribution plate 2 rotates at a certain angle by switching with the water inlet seat 13 through the reversing component, so that the water distribution hole 24 of the water distribution plate 2 is connected with different water outlet holes 142 on the water outlet body 14.

[0062] The aforementioned remote switching structure, since the water distribution plate 2 is installed inside the water outlet device 1, not only enables the switching of multiple water sprays, but also makes the installation method of the shower with this water outlet device 1 the same as that of a traditional shower with only one water spray. There will be no additional construction difficulty due to remote switching, and the installation is convenient and quick. If there is already a water outlet device in the home, it can be replaced with a water outlet device with the above-mentioned switching structure to achieve remote switching without adjusting the water inlet circuit, which is economical and affordable.

[0063] The angle rotation scheme adopted in this embodiment is as follows: when the water distribution plate 2 moves from the first position to the second position, the water distribution plate 2 rotates at a first angle A by reversing its engagement with the water inlet seat 13 through the first reversing component; when the water distribution plate 2 moves from the second position to the first position, the water distribution plate 2 rotates at a second angle B by reversing its engagement with the water outlet body 14 through the second reversing component.

[0064] The advantage of this rotation method is that the rotation angle of the water distribution plate 2 is completed simultaneously during both the rising and falling processes of the water distribution plate 2. If it only rotates during the rising process or only during the falling process, then the rising or falling stroke of the water distribution plate 2 needs to be lengthened to ensure that the water distribution plate 2 can rotate a sufficient angle. In this case, the thickness of the water outlet device 1 needs to be increased, which would make it less aesthetically pleasing.

[0065] In this embodiment, the first reversing component is a first helical tooth 21 disposed on the top of the water distribution plate 2 and a first mating helical tooth 131 disposed on the water inlet seat 13. The second reversing component is a second helical tooth 22 disposed on the bottom of the water distribution plate 2 and a second mating helical tooth 141 disposed on the water outlet body 14.

[0066] It should be noted that in this scheme, after the water distribution plate 2 rotates at the first angle A, the second helical tooth 22 and the second mating helical tooth 141 should be in a staggered state. In this way, when the water distribution plate 2 descends, the second helical tooth 22 and the second mating helical tooth 141 can switch directions to drive the water distribution plate 2 to rotate at the second angle B.

[0067] In this embodiment, in order to lower the water distribution plate 2, the method adopted is to change the direction of the force exerted by the water flow on the water distribution plate 2. For this purpose, the water inlet seat 13 also has a second flow channel 15, and the valve core 12 is used to switch the first flow channel 11 and the second flow channel 15.

[0068] The second flow channel 15 has a second outlet 151 connected to the water distribution plate 2. The first outlet 111 is lower than the lower surface of the water distribution plate 2 along the water flow direction, and the second outlet 151 is higher than the upper surface of the water distribution plate 2 along the water flow direction. This allows the water flowing from the first outlet 111 and the second outlet 151 to act on the water distribution plate 2 in different directions.

[0069] When the water distribution plate 2 is in the second position, the valve core 12 opens the second flow channel 15 and closes the first flow channel 11.

[0070] When the second flow channel 15 is opened, the force exerted by the water flow on the water distribution plate 2 changes from upward to downward, thereby pushing the water distribution plate 2 to move downward.

[0071] To enable the valve core 12 to open the second flow channel 15 and close the first flow channel 11, the water distribution plate 2 has a damping hole 23 connecting the first outlet 111 and the second outlet 151; as Figure 3 When the first flow channel 11 is opened, the water flowing out of the first flow channel 11 acts upward on the water distribution plate 2, causing the water distribution plate 2 to move upward and abut against the bottom surface 132 of the water inlet seat 13. Then the water flows through the damping hole 23 into the second flow channel 15. The water pressure on both sides of the valve core 12 is similar to the principle of communicating vessels, and the water pressure tends to be equal. Since the area of ​​the valve core 12 receiving water pressure to the left is greater than the area receiving water pressure to the right, it pushes the valve core 12 to move to the left, thereby causing the seal 121 on the valve core 12 to separate from the seal between the second flow channel 15 and the water inlet, opening the second flow channel 15. Under the action of the water pressure in the second flow channel 15, the valve core 12 keeps the second flow channel 15 in the open state. At the same time, after the seal 121 on the valve core 12 moves, it seals the first flow channel 11 with the water inlet, thereby closing the first flow channel 11. Figure 4 As shown.

[0072] After the second flow channel 15 is opened, the water flows from the inlet through the second flow channel 15 and then from the water distribution port 24 on the water distribution plate 2 into the water outlet hole 142 of the water outlet body 14, thus realizing the normal water outlet process. When the water is turned off, the valve core 12 resets. The above switching process is repeated the next time the water is turned on, so that the water outlet changes once every time the water is turned on.

[0073] In order to achieve the reset of the valve core 12 after the water is turned off, the valve core 12 is fitted with an elastic element 16. When the second flow channel 15 is opened, the elastic element 16 is squeezed by the valve core 12 and accumulates elastic reset force.

[0074] In this embodiment, the water outlet device is a top-mounted shower head. The shower head's outlet cover has numerous water nozzles, each connected to a different water outlet hole 142. Therefore, when the water distribution plate 2 rotates once, water flows from different water outlet holes 142, and water also flows from the different water nozzles on the outlet cover. This is a scheme where different water outlet holes produce different water sprays. As a simpler alternative, different water sprays could also be produced from the same water outlet hole.

[0075] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
