Description

Technical Field

[0001] The present invention relates to the technical field of bathrooms, and in particular to a water inlet valve and a toilet. Background Art

[0002] When flushing, a siphonic toilet flushes away some of the water trapped in the trap. Therefore, this water needs to be replenished after the drain valve is closed to prevent sewer odors from entering the bathroom through the trap. In the related art, a water replenisher is usually required to replenish this water. Water replenishers are mainly divided into external water replenishers and integrated water replenishers. External water replenishers are generally fixed to the overflow pipe, through which water enters the trap. The advantage is that the external water replenisher is easy to install and adjust, but the disadvantage is that it is large in size, complex in structure, and relatively high in manufacturing cost. The integrated water replenisher is generally integrated into the drain valve or flush button. The advantage is the simple structure, but it will make the flush button feel heavier, resulting in a poor user experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a water inlet valve with a relatively simple structure and does not aggravate the feel of the flush button.

[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0052] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0053] The water inlet valve 1000 of the toilet 2000 is primarily controlled by the water inlet float 430 to open and close. When the user presses the flush button, the water level in the toilet tank 2300 drops, and the water inlet float 430 follows suit, opening the water inlet valve 1000. As the water level in the tank 2300 gradually rises, driving the water inlet float 430 to a preset height, the valve closes, stopping water inflow. The present invention proposes a water inlet valve 1000 with an integrated water replenishment mechanism that effectively replenishes water in the toilet 2000's water trap. It features a simple structure and does not aggravate the flushing experience.

[0054] Reference Figure 1 、 Figure 2 and Figure 3As shown, in an embodiment of the present invention, the water inlet valve 1000 includes a valve body 100, a water distribution member 200, and a switch 300. The valve body 100 has a water inlet channel 121 and a water outlet channel 111. The water inlet channel 121 can be connected to an external water pipe, and the water outlet channel 111 is used to discharge water into the water tank 2300 of the toilet 2000. The water distribution member 200 is disposed within the valve body 100. The water distribution member 200 is also provided with a water diversion chamber 210, a water replenishment port 220, and a first water outlet 230. The water inlet channel 121 is connected to the water outlet channel 111 through the first water outlet 230, so that water can enter the water tank 2300 through the water inlet channel 121, the first water outlet 230, and the water outlet channel 111 in sequence. The water inlet channel 121 is connected to the water supply port 220 through the water diversion chamber 210, so water can pass through the water inlet channel 121, the water diversion chamber 210 and the water supply port 220 in sequence, and finally enter the water trap (not shown in the figure) of the toilet 2000 for water supply.

[0055] The switch 300 includes a transmission structure 310, a water replenishment float 320, and a valve core 330. The valve core 330 is installed in the water diversion chamber 210, and the transmission structure 310 connects the water replenishment float 320 and the valve core 330. Because the water replenishment float 320 can rise and fall with the liquid level in the water tank 2300, the water replenishment float 320 can drive the valve core 330 to rotate through the transmission structure 310. The water replenishment float 320 has a first position and a second position. When the water replenishment float 320 is in the first position, the valve core 330 closes the water replenishment port 220. When the water replenishment float 320 is in the second position, the valve core 330 opens the water replenishment port 220. At this time, the toilet 2000 can replenish the water trap, effectively preventing sewer odors from entering the room through the trap.

[0056] By disposing the water diverter 200 within the valve body 100, the first water outlet 230 of the water diverter 200 connects to the water inlet channel 121 and the water outlet channel 111 of the valve body 100, the water diverter chamber 210 of the water diverter 200 connects to the water inlet channel 121 and the water replenishment port 220, the valve core 330 is installed within the water diverter chamber 210, and the transmission structure 310 is connected to the water replenishment float 320 and the valve core 330. Therefore, when the flush button is pressed and the water tank 2300 of the toilet 2000 begins to fill with water, water enters through the water inlet channel 121 of the valve body 100 and finally enters the water tank 2300 through the water outlet channel 111. As the liquid level in the water tank 2300 gradually rises, the water replenishment float 320 can switch between the first position and the second position in response to the change in the liquid level, thereby driving the transmission structure 310 to move, and the transmission structure 310 can drive the valve core 330 to rotate. When the water replenishment float 320 is in the first position, the valve core 330 closes the water replenishment port 220. When the water level in the water tank 2300 gradually rises, the water replenishment float 320 moves to the second position. During this process, the valve core 330 rotates under the drive of the transmission structure 310 to open the water replenishment port 220. At this time, water passes through the water inlet channel 121, the water diversion chamber 210, the water replenishment port 220, and finally enters the overflow pipe 2200, flowing to the water trap of the toilet 2000 for replenishment. Because the water replenishment structure is integrated into the water inlet valve 1000, it has a simple structure, is easy to manufacture and install, and does not aggravate the feel of the flush button, providing a better user experience.

[0057] It should be noted that when the first position is below the second position, that is, during the process of water filling the water tank 2300, the water filling port 220 is controlled by a closing-then-opening control logic. This solution is applicable to a dual-flush toilet 2000. It is understood that the amount of water remaining in the water tank 2300 varies after pressing different flushing positions in a dual-flush toilet 2000. For example, a toilet 2000 has two flushing positions: full flush and half flush. After pressing the full flush button, the amount of water remaining in the water tank 2300 is less than the half flush. If the water filling port 220 is controlled by an opening-then-closing control logic, since the liquid level in the water tank 2300 is lower during a full flush, the water filling float 320 will take longer to rise to the preset height during a full flush than during a half flush, resulting in a larger amount of water being filled during a full flush than during a half flush. Therefore, the water supply port 220 adopts a control logic of closing first and then opening. This allows the water inlet valve 1000 to open the water supply port 220 after the liquid level rises to a certain height. This ensures that the water supply amount is basically the same after pressing different flush gears, rather than opening the water supply port 220 from the beginning, which would prevent the water supply amount from being different and lead to water waste. It should also be noted that since the valve of the water inlet valve 1000 will be closed after the liquid level in the water tank 2300 rises to a preset height, the water supply will also stop, and there is no need to worry about the water supply being continuously replenished.

[0058] When the first position is above the second position, that is, when the water supply port 220 opens first and then closes, it is suitable for a single-flush toilet 2000. It will be appreciated that when the flush button is pressed, the liquid level in the water tank 2300 drops, and the water supply port 220 opens, allowing water to be replenished into the trap. When the liquid level rises to a preset height, the water supply port 220 closes. Therefore, adopting a solution in which the water supply port 220 opens first and then closes ensures a substantially constant water supply volume, effectively reducing water waste.

[0059] It should also be noted that when the first position is below the second position, it can also be applied to a single-flush toilet 2000; when the first position is above the second position, it can also be applied to a double-flush toilet 2000. The appropriate solution should be selected according to the actual situation. The subsequent embodiments of the present invention are all illustrated by taking the case where the first position is below the second position as an example.

[0060] Reference Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment of the present invention, the outer wall of the valve body 100 is provided with a water supply connector 112 and an installation port 114. The installation port 114 communicates with the water diversion chamber 210. The installation port 114 is used to install the valve core 330, allowing the valve core 330 to pass through the installation port 114 and then be installed in the water diversion chamber 210. The water diversion member 200 is provided with a water flow channel 221 located below the water supply port 220. The water supply port 220 communicates with the inner cavity of the water supply connector 112 through the water flow channel 221. Therefore, water can enter the water flow channel 221 from the water supply port 220 and then enter the water supply connector 112. It is understood that the design of the water flow channel 221 and the water supply connector 112 facilitates the removal of water from the water inlet valve 1000. The water supply connector 112 can be connected to an external water supply pipe 130. The water supply pipe 130 is made of a flexible hose, which facilitates connection to the water supply connector 112 and the diversion of water to the overflow pipe 2200. In another embodiment of the present invention, the water trough 221 may also be located above or on the side of the water supply port 220, so as to transport water to a higher place by increasing the water pressure.

[0061] Reference Figure 7 、 Figure 8 and Figure 12 As shown, in the embodiment of the present invention, the valve core 330 includes a rotating shaft 335 and a water retaining portion 331. The water retaining portion 331 is provided on the outer peripheral wall of the rotating shaft 335 and is used to block the water supply port 220. One end of the rotating shaft 335 is rotatably connected to the rotating hole 212 located in the water diversion chamber 210 to ensure the stability of the rotation of the valve core 330. When the water supply buoy 320 is in the first position, the water retaining portion 331 can block the water supply port 220, for example Figure 8 In the state shown in , water cannot pass through the water replenishment port 220, which facilitates the control of the switch of the water replenishment port 220.

[0062] Reference Figure 7 and Figure 8 As shown, in the embodiment of the present invention, a water passage 332 is formed between the water retaining portion 331 and the rotating shaft 335. When the water replenishment buoy 320 is located at the second position, the water diversion chamber 210 is connected to the water replenishment port 220 through the water passage 332, for example Figure 7 At this time, water can be replenished through the water replenishment port 220, which facilitates the passage of water through the water replenishment port 220. Therefore, by rotating the valve core 330 to different positions, the water replenishment port 220 can be opened or closed.

[0063] Reference Figure 6 and Figure 12 As shown, in an embodiment of the present invention, there are two water retaining parts 331 and they are spaced apart along the axial direction of the rotating shaft 335. A limiting groove 333 is formed between the two water retaining parts 331, and the limiting groove 333 is located at one end of the valve core 330 close to the rotating hole 212. The water distribution part 200 is provided with a limiting block 211, and the limiting block 211 is located in the water distribution chamber 210. When the valve core 330 is installed in the water distribution chamber 210, the limiting block 211 and the limiting groove 333 cooperate to limit the rotation angle of the valve core 330, thereby ensuring the accuracy of the rotation of the valve core 330, ensuring that the valve core 330 can open or close the water supply port 220, and improving the reliability of the water inlet valve 1000. In another embodiment of the present invention, there can be more than two water retaining parts 331, and they are spaced apart along the outer periphery of the rotating shaft 335. The appropriate solution is selected according to the actual situation, and the present invention is no longer specifically limited here.

[0064] Reference Figure 4 and Figure 11 As shown, in this embodiment of the present invention, the switch 300 further includes a fixing member 340 and a decorative cover 350. The end of the valve core 330 away from the rotating hole 212 is called the tail end, and the fixing member 340 is sleeved on the tail end of the valve core 330. The outer wall of the fixing member 340 is provided with a snap, and the side wall of the mounting opening 114 is provided with a snap. The snap and the snap engage to prevent the valve core 330 from being disengaged from the water diversion chamber 210. A through hole is provided at the connection between the rotating rod 312 and the valve core 330. The side wall of the through hole protrudes inward to form two locking blocks 3121. Both locking blocks 3121 engage with the slot 334 at the tail end of the valve core 330, so that the rotating rod 312 can drive the valve core 330 to rotate. The decorative cover 350 is provided with a connecting shaft, which passes through the through hole of the rotating rod 312 and is connected to the tail end of the valve core 330. The decorative cover 350 is used to limit the rotating rod 312 from separating from the valve core 330 and improve the aesthetics of the rotating rod 312.

[0065] Reference Figure 9As shown, in the embodiment of the present invention, a boss 250 is provided on the inner side of the bottom wall of the water diversion member 200, and a first water outlet 230 is provided on the boss 250. The inner side of the bottom wall refers to one side located on the annular cavity 280. It will be appreciated that providing the first water outlet 230 on the boss 250 facilitates adjustment of the size of the first water outlet 230 during the design phase, reducing design complexity.

[0066] Reference Figure 10 As shown, in this embodiment of the present invention, a spiral channel 260 is provided on the outer wall of the water diversion member 200. The spiral channel 260 is located below and communicates with the first water outlet 230. The spiral channel 260 also communicates with the water outlet channel 111. As will be appreciated, since water passing through the first water outlet 230 enters the spiral channel 260 and then the water outlet channel 111, it can flow downward along the inner wall of the valve body 100 without directly impacting downward. This reduces noise when water enters the water tank 2300, improving the user experience.

[0067] Reference Figure 6 、 Figure 7 and Figure 8 As shown, in the embodiment of the present invention, the water diversion member 200 is provided with a second water outlet 240 in the water diversion chamber 210. The second water outlet 240 connects the water outlet channel 111 and the water diversion chamber 210. When the water replenishment buoy 320 is in the first position, the transmission structure 310 drives the valve core 330 to rotate, causing the valve core 330 to open the second water outlet 240. When the water replenishment buoy 320 is in the second position, the transmission structure 310 drives the valve core 330 to rotate, causing the valve core 330 to close the second water outlet 240. It is understood that when the water replenishment port 220 is open, the second water outlet 240 is closed, and when the water replenishment port 220 is closed, the second water outlet 240 is open. It should be noted that the purpose of providing the second water outlet 240 is that if there is only one first water outlet 230, before the water inlet 220 is opened, the water pressure within the water diversion member 200 is high, and the pressure applied to the valve core 330 is relatively high. This increases the friction between the valve core 330 and the inner wall of the water diversion chamber 210, and the transmission structure 310 may be unable to drive the valve core 330 to rotate. Therefore, providing the second water outlet 240 can be used to relieve pressure, reduce the impact of water pressure on the valve core 330, and improve the reliability of the water inlet valve 1000.

[0068] Reference Figure 6 As shown, in the embodiment of the present invention, an annular groove 290 is provided on the outer wall of the water diversion member 200, and the annular groove 290 is arranged around the water diversion chamber 210 and the water flow groove 221. A sealing ring (not shown in the figure) is provided in the annular groove 290, and the sealing ring abuts against the inner wall of the valve body 100, effectively preventing water from leaking from the opening of the water diversion chamber 210.

[0069] Reference Figure 5 and Figure 6 As shown, in this embodiment of the present invention, a sleeve 270 is provided within the water diversion member 200. The sleeve 270 is spaced from the inner wall of the water diversion member 200, thereby forming an annular cavity 280 between the sleeve 270 and the inner wall of the water diversion member 200. The water inlet channel 121 communicates with the water diversion cavity 210 via the annular cavity 280, allowing water to sequentially flow through the water inlet channel 121, the annular cavity 280, the water diversion cavity 210, and the water replenishment port 220. The valve body 100 includes an outer shell 110 and an inner tube 120, which is disposed within the outer shell 110. The inner tube 120 is inserted through the sleeve 270 of the water distribution member 200 and defines an inlet channel 121 therein. A water outlet channel 111 is defined between the outer wall of the inner tube 120 and the inner wall of the outer shell 110. The lower sidewall of the outer shell 110 is provided with a water outlet 113 connected to the outlet channel 111. Water finally enters the water tank 2300 from the outlet 113. It is understood that water enters from the bottom of the water inlet valve 1000 and finally flows downward along the outlet channel 111, entering the lower part of the water tank 2300. This effectively improves the situation where water is directly sprayed into the water tank 2300 from above, causing noise. It should be noted that in another embodiment of the present invention, the inlet channel 121 can also be located above the valve body 100, with an external water pipe connected to facilitate water supply. The appropriate solution should be selected based on actual conditions, and the present invention will not be further limited herein.

[0070] Reference Figure 4 As shown, in an embodiment of the present invention, the outer wall of the outer shell 110 is provided with a guide rail 150 extending in the vertical direction, or in other words, extending along the length direction of the valve body 100. The water replenishment float 320 and the guide rail 150 are slidably connected to effectively limit the position of the water replenishment float 320 and improve the accuracy of the movement of the water replenishment float 320. It can be understood that in the related art, the external water replenisher needs to use a fixed frame as a guide device, so the fixed frame structure is additionally added. In an embodiment of the present invention, the guide rail 150 is set on the outer wall of the outer shell 110, and the structure of the water inlet valve 1000 itself is used as the fulcrum of the water replenisher, so its structure is simple, no additional fixed frame is required, the manufacturing cost is low, and the economic benefit is good.

[0071] Reference Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the transmission structure 310 includes an adjustment rod 311 and a rotating rod 312. The adjustment rod 311 is arranged vertically and connected to the water replenishment buoy 320. The water replenishment buoy 320 can drive the adjustment rod 311 to move vertically. One end of the rotating rod 312 is movably connected to the upper end of the adjustment rod 311, while the other end of the rotating rod 312 is fixedly connected to the rear end of the valve core 330. Therefore, when the water replenishment buoy 320 drives the adjustment rod 311 to move vertically, it can cause the rotating rod 312 to swing, which in turn causes the rotating rod 312 to rotate the valve core 330. This simple structure and reliable operation.

[0072] Reference Figure 4 As shown, in this embodiment of the present invention, the outer wall of the adjustment rod 311 is provided with an external thread extending along the length of the adjustment rod 311. The water replenishment buoy 320 is provided with an internal thread (not shown). When the adjustment rod 311 is inserted into the water replenishment buoy 320, the internal thread engages with the external thread. It is understood that the threaded engagement between the adjustment rod 311 and the water replenishment buoy 320 allows for convenient adjustment of the position of the water replenishment buoy 320 on the adjustment rod 311 by rotating the adjustment rod 311, thereby varying the amount of water replenished. For example, adjusting the initial position of the water replenishment buoy 320 downwards brings the water replenishment buoy 320 closer to the bottom of the water tank 2300. As the water level in the water tank 2300 rises, the water replenishment buoy 320 can more quickly contact the water surface, thereby floating up and opening the water replenishment port 220 for water replenishment. Therefore, adjusting the water replenishment buoy 320 downwards can increase the amount of water replenished. When the water replenishment float 320 is adjusted upward, it moves away from the bottom of the water tank 2300. Because the water replenishment float 320 is higher from the water surface of the water tank 2300, it takes longer to open the water replenishment port 220, thereby reducing the amount of water replenished. Therefore, the water inlet valve 1000 can adjust the amount of water replenishment based on different toilets 2000 and user habits, improving the versatility of the water inlet valve 1000 and enhancing the user experience.

[0073] It is understood that the water inlet valve 1000 is typically equipped with a delayed water inlet function. This delayed water inlet function means that when the toilet 2000 is flushed, the water tank 2300 does not immediately fill with water, but waits for a period of time before filling. This prevents the water tank 2300 from filling with water simultaneously with the flush, which would otherwise waste water resources. Therefore, the delayed water inlet function can ensure an appropriate amount of water replenishment and reduce waste.

[0074] Specifically, refer to Figure 13 and Figure 14As shown, the water inlet valve 1000 includes a valve assembly 400, which includes a rotating arm 410, a transmission rod 420, a water inlet buoy 430, a float 440, and a float plug 450. The float 440 is fixedly connected to the outer shell 110. The interior of the float 440 defines a water storage chamber 441. A clearance is defined between the float 440 and the outer shell 110 to facilitate the upward and downward movement of the water replenishment buoy 320, thereby improving the rationality of the water inlet valve 1000. The water inlet buoy 430 is located within the water storage chamber 441 and is connected to the transmission rod 420. Therefore, the water inlet buoy 430 can drive the transmission rod 420 to rise or fall. The transmission rod 420 is rotatably connected to the rotating arm 410. When the transmission rod 420 moves up and down, it drives the rotating arm 410 to rotate. Therefore, the other end of the rotating arm 410 can open or close the pressure relief hole 140, thereby allowing or stopping water inlet to the water inlet valve 1000. The float plug 450 is disposed at the bottom of the float barrel 440 , and the water in the water storage chamber 441 can slowly leak out from the connection between the float barrel 440 and the float plug 450 .

[0075] Therefore, the delayed water inflow process is roughly as follows: during flushing, the water in the float bucket 440 does not descend synchronously with the water in the water tank 2300, but instead slowly leaks out at the connection between the float plug 450 and the float bucket 440. Therefore, the water inlet buoy 430 in the float bucket 440 does not descend immediately. Instead, the rotating arm 410 waits until the water level in the float bucket 440 drops to a preset position before opening the pressure relief hole 140. At this point, the water inlet valve 1000 can normally inlet water. Therefore, the delayed water inflow design can reduce water waste. It should be noted that a leak hole 442 can also be provided at the bottom of the float bucket 440 to assist in water leakage. Alternatively, the leak hole 442 and the float plug 450 can be combined. The appropriate solution can be selected based on actual circumstances, and the present invention is not specifically limited here.

[0076] A toilet 2000 according to one embodiment of the present invention includes the water inlet valve 1000 according to the above-described embodiment, which is installed within a water tank 2300 of the toilet 2000. The toilet 2000 according to this embodiment of the present invention utilizes the water inlet valve 1000 according to the first embodiment, wherein a water diverter 200 is disposed within a valve body 100, a first water port 230 of the water diverter 200 communicating with a water inlet channel 121 and a water outlet channel 111 of the valve body 100, a water diverter chamber 210 of the water diverter 200 communicating with the water inlet channel 121 and a water replenishment port 220, a valve core 330 installed within the water diverter chamber 210, and a transmission structure 310 connected to the water replenishment buoyancy housing 320 and the valve core 330. Therefore, when the flush button is pressed and water starts to flow into the water tank 2300 of the toilet 2000, the water will enter along the water inlet channel 121 of the valve body 100 and finally enter the water tank 2300 along the water outlet channel 111. As the liquid level in the water tank 2300 gradually rises, the water replenishment float 320 can switch between the first position and the second position according to the change in the height of the liquid level, thereby driving the transmission structure 310 to move, and the transmission structure 310 can drive the valve core 330 to rotate. When the water replenishment float 320 is in the first position, the valve core 330 closes the water replenishment port 220. When the water level in the water tank 2300 gradually rises, the water replenishment float 320 moves to the second position. During this process, the valve core 330 rotates under the drive of the transmission structure 310 to open the water replenishment port 220. At this time, water passes through the water inlet channel 121, the water diversion chamber 210, the water replenishment port 220, and finally enters the overflow pipe 2200, flowing to the water trap of the toilet 2000 for replenishment. Because the water replenishment structure is integrated into the water inlet valve 1000, it has a simple structure, is easy to manufacture and install, and does not aggravate the feel of the flush button, providing a better user experience.

[0077] Since the toilet adopts all the technical solutions of the water inlet valve of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described in detail here.

[0078] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
