Description

Technical Field

[0001] The invention relates to a water pressure automatic switching and automatic resetting device. Background Art

[0002] Water outlet devices are widely used, and with the increasing demand for water outlet devices, many water outlet components have the function of switching the water outlet mode. Currently, most water outlet devices on the market that can switch the water outlet mode require users to manually operate the switch button on the water outlet device to switch. This switching method has the following problems:

[0003] 1. Setting a manual switch on the water outlet device is not only troublesome to use, but also the drive components with a long power transmission chain are prone to damage and failure after repeated use;

[0004] 2. Setting a switch on the water outlet device results in poor integrity of the outer pipe of the water outlet device, which is not only weak in strength and easy to break, but also easy to get stuck and enter dust;

[0005] 3. The water outlet device with a toggle switch often does not have an automatic reset function, that is, after the user switches, the water outlet component will not automatically return to the initial water outlet mode when used next time.

[0006] This shows that the existing water outlet device needs to be improved. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention proposes a structure that can automatically switch or automatically restore the initial water outlet mode under water pressure control.

[0008] A water pressure automatic switching and automatic resetting device comprises a housing, a waterway switching assembly, a switching drive assembly and a resetting drive assembly, wherein:

[0009] The housing includes a water inlet, a water inlet channel, a first water outlet channel, and a second water outlet channel. One end of the water inlet channel is connected to the water inlet, and the other end is connected to the first water outlet channel or the second water outlet channel via the water channel switching assembly. The water channel switching assembly includes a switching structure and a reset structure. The switching structure controls the water channel switching assembly to switch the water channel, allowing the water inlet channel to switch from one water outlet channel to another. The reset structure controls the water channel switching assembly to switch the water inlet channel to a preset water outlet channel, thereby achieving an automatic reset function.

[0010] The switching drive assembly is mounted within the housing and includes an instant reset member and a switching lever. One end of the switching lever is connected and driven by the instant reset member, while the other end extends into the water inlet channel and points toward the switching structure. The instant reset member is connected to the water inlet channel. When water enters the water inlet channel, the water pressure drives the instant reset member and drives the switching lever away from the water path switching assembly. When the water is turned off, the water pressure disappears, and the instant reset member, through a reset action, drives the switching lever to operate the water path switching assembly, achieving a single water path switching.

[0011] The reset drive assembly is mounted within the housing and includes a delayed reset member and a reset lever. One end of the reset lever is connected to and driven by the delayed reset member, while the other end extends into the water inlet channel and points toward the reset structure. The delayed reset member is connected to the water inlet channel. When water enters the water inlet channel, the water pressure drives the delayed reset member and drives the delayed lever away from the waterway switching assembly. When the water is turned off, the water pressure disappears, and the delayed reset member, through a delayed reset action, drives the switch lever to operate the waterway switching assembly, thereby resetting the waterway.

[0012] The present invention is provided with a switching structure and a reset structure, and at the same time provides a switching drive component and a reset drive component that can reset in time and with delay after the water is turned off, thereby realizing automatic switching of the water channel at the moment of turning off the water, and realizing automatic switching of the water channel to the initial state after a period of time after turning off the water.

[0013] Preferably, a water-blocking baffle is provided in the water inlet channel. The water-blocking baffle is provided with a first water outlet hole and a second water outlet hole. There is at least one first water outlet hole and at least one second water outlet hole, and the holes are sequentially arranged around the same center of a circle. The first water outlet hole is connected to the first water outlet channel, and the second water outlet hole is connected to the second water outlet channel.

[0014] The water channel switching assembly includes a water diversion plate and a toothed plate. The water diversion plate is tightly attached to the water baffle and is rotatably arranged. The water diversion plate is provided with a water diversion hole connected to the first water outlet or the second water outlet. The toothed plate is installed on the top of the water diversion plate and is connected to drive the water diversion plate to rotate. Specifically, the outer periphery of the toothed plate is provided with two layers of evenly distributed teeth, namely: switching teeth located in the extension direction of the switching rod, serving as the switching structure. Reset teeth located in the extension direction of the reset rod, serving as the reset structure.

[0015] When the water pressure disappears, the switch lever is reset in time and the switch gear pushes the toothed disc to rotate, thereby switching the waterway. After the water is turned off for a period of time, the reset lever is reset after a delay and the reset gear pushes the toothed disc to rotate, thereby restoring the waterway to its original state.

[0016] Preferably, the switching teeth are located above the reset teeth.

[0017] Preferably, the number of the switching teeth is equal to the sum of the first and second water outlet holes, and the positions of the switching teeth correspond one-to-one with the first and second water outlet holes. The number of the reset teeth is half that of the switching teeth, and they are flush with half of the switching teeth, and their positions correspond one-to-one with the first or second water outlet holes. This allows the reset rod to push the reset teeth to a preset angle, regardless of the current angle of the toothed disc, and connect the first or second water outlet hole (the preset water outlet hole) to the water diversion hole, thereby switching the water path to the initial water outlet state.

[0018] Preferably, the water-blocking baffle is provided with a circular ring surrounding the first water outlet and the second water outlet. The outer periphery of the first water outlet and the second water outlet are both provided with an annular groove, and a sealing ring is placed in the annular groove to prevent communication between different water outlets. The water diversion plate is arranged in the circular ring and close to the water-blocking baffle, and the installation is stable and reliable. An upwardly extending limiting column is provided at the center of the water diversion plate. A limiting hole consistent with the cross-section of the limiting column is provided in the middle of the toothed disc, and the toothed disc is installed on the limiting column of the water diversion disc through the limiting hole. A card pointing to the teeth of the toothed disc is also provided on the water-blocking baffle to prevent the toothed disc from reversing.

[0019] Preferably, the water inlet channel is provided with a switch lever telescopic hole and a water passage hole around its periphery. The instant reset element comprises a switch cylinder, a switch block, a switch stopper, and a switch spring. One end of the switch cylinder is mounted around the water inlet channel, covering the switch lever telescopic hole and the water passage hole. The switch block is slidably mounted within the switch cylinder. The switch stopper is disposed at the other end of the switch cylinder. The switch spring is preloaded and disposed between the switch block and the switch stopper. One end of the switch rod is mounted on the switch block, while the other end passes through the switch lever telescopic hole and is provided with a curved push-up head directed toward the switch mechanism. When water enters the water inlet channel, water enters the switch cylinder through the water passage hole and hydraulically squeezes the switch block, causing the switch block to retract, thereby simultaneously driving the switch rod backward. When the water is turned off, the switch spring causes the switch block to quickly drain water through the water passage hole and reset itself, simultaneously driving the switch rod to reset and controlling the water path switching assembly, switching the water path. This allows the user to switch the water path immediately after turning the water off and back on, providing a different water flow method.

[0020] Preferably, a Y-shaped sealing ring is provided between the periphery of the switching block and the inner wall of the switching cylinder to improve the reliability of the instant reset member.

[0021] Preferably, a reset rod telescopic hole is provided on the periphery of the water inlet channel. The delayed reset component includes a reset cylinder, a reset block, a reset stopper and a reset spring, wherein one end of the reset cylinder is mounted on the periphery of the water inlet channel and covers the reset rod telescopic hole. The reset block is slidably mounted in the reset cylinder. The reset stopper is arranged at the other end of the reset cylinder. The reset spring is pre-tightened and arranged between the reset block and the reset stopper. One end of the reset rod is mounted on the reset block, and the other end passes through the reset rod telescopic hole and is provided with an arc-shaped pushing head pointing to the switching structure. A water seepage groove is provided between the reset rod and the reset rod telescopic hole. The water seepage groove connects the water inlet channel and the reset cylinder. When water enters the water inlet channel, water enters the reset cylinder through the water seepage groove and squeezes the reset block through hydraulic pressure, thereby achieving the retreat of the reset block and driving the reset rod to retreat at the same time. When the water is turned off, due to the action of the reset spring, the reset block slowly discharges the water through the seepage groove and resets it, while driving the switching rod to slowly reset and control the water channel reset component to achieve delayed reset of the water channel. When the user turns on the water again after a period of time, the initial water outlet mode can be obtained.

[0022] Preferably, the water seepage groove is a strip groove provided on the periphery of the reset rod. A Y-shaped sealing ring is provided between the periphery of the reset block and the inner wall of the reset cylinder to improve the reliability of the delayed reset element.

[0023] Preferably, the housing comprises, from top to bottom, a top cover, an inner frame, a first water outlet panel, a second water outlet panel, and a bottom cover. The water inlet channel, the first water outlet channel, the second water outlet channel, and the water baffle are all disposed on the inner frame. The first and second water outlet panels are mounted on the bottom or periphery of the inner frame and are connected to the first and second water outlet channels, respectively. The top cover seals the top of the inner frame and is provided with an inlet connector for docking with the water inlet channel. The bottom cover seals the bottom of the inner frame, the first and second water outlet panels.

[0024] From the above description of the present invention, it can be seen that the present invention has the following beneficial effects:

[0025] 1. By setting up a switching structure and a reset structure, and providing a switching drive component and a reset drive component that can reset in time and with delay after the water is turned off, the water channel can be automatically switched at the moment the water is turned off, and the water channel can be automatically switched to the initial state after a period of time after the water is turned off;

[0026] 2. Instead of setting a switch structure on the water outlet device, it improves the integrity of the water outlet device shell and the stability and reliability of installation;

[0027] 3. It is powered by water pressure, with ingenious structure and high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] See also Figures 1 to 4 A water pressure automatic switching and automatic resetting device includes a housing 1, a waterway switching component 2, a switching drive component 3 and a resetting drive component 4, wherein:

[0041] The housing 1 includes a water inlet 11, a water inlet channel 12, a first water outlet channel 13, and a second water outlet channel 14. One end of the water inlet channel 12 is connected to the water inlet 11, and the other end is connected to the first water outlet channel 13 or the second water outlet channel 14 through the water channel switching component 2. The water channel switching component 2 includes a switching structure and a reset structure. The switching structure can control the water channel switching component 2 to switch the water channel, allowing the water inlet channel 12 to switch from one water outlet channel to another. The reset structure can control the water channel switching component 2 to switch the water inlet channel 12 to a preset water outlet channel, thereby realizing the automatic reset function.

[0042] In one embodiment, a water barrier 121 is provided within the water inlet channel 12. The water barrier 121 is provided with a first water outlet hole 1211 and a second water outlet hole 1212. There is at least one first water outlet hole 1211 and at least one second water outlet hole 1212, and the holes are sequentially arranged around the same center of a circle. The first water outlet hole 1211 communicates with the first water outlet channel 13, and the second water outlet hole 1212 communicates with the second water outlet channel 14.

[0043] The water channel switching assembly 2 includes a water diversion plate 21 and a toothed plate 22. The water diversion plate 21 is tightly attached to the water baffle 121 and is rotatably arranged. The water diversion plate 21 is provided with a water diversion hole 211 connected to the first water outlet 1211 or the second water outlet 1212. The toothed plate 22 is installed on the top of the water diversion plate 21 and is connected to drive the water diversion plate 21 to rotate. Specifically, the outer periphery of the toothed plate 22 is provided with two layers of evenly distributed teeth, namely: the switching teeth 221 located in the extension direction of the switching rod 32, serving as the switching structure. The reset teeth 222 located in the extension direction of the reset rod 42 serve as the reset structure. Optionally, the switching teeth 221 are located on the upper layer of the reset teeth 222.

[0044] The number of the switching teeth 221 is equal to the sum of the first water outlet holes 1211 and the second water outlet holes 1212, and the positions of the switching teeth 221 correspond one-to-one with the first water outlet holes 1211 and the second water outlet holes 1212. When the water pressure disappears, the switching lever 32 is promptly reset and the switching teeth 221 push the toothed disc 22 to rotate, thereby switching the water path.

[0045] The number of the reset teeth 222 is half of the switching teeth 221, and is flush with the working surface of half of the switching teeth 221, and the position corresponds one-to-one to the first water outlet 1211. After the water is turned off for a period of time, the reset rod 42 is reset with a delay and the reset teeth 222 push the toothed disc 22 to rotate, so that the water path is restored to its initial state: when the reset rod 42 pushes the reset teeth 222, no matter what the current angle of the toothed disc 22 is, it can push the reset teeth 222 to a preset angle and connect the first water outlet 1211 (in this embodiment, the first water outlet 1211 serves as the initial water outlet) with the water diversion hole 211, so as to switch the water path to the initial water outlet state.

[0046] In other embodiments, the water-blocking baffle 121 is provided with a circular ring 1213 surrounding the first water outlet 1211 and the second water outlet 1212. The outer peripheries of the first water outlet 1211 and the second water outlet 1212 are both provided with an annular groove, and a sealing ring is placed in the annular groove to prevent communication between different water outlets. The water diversion plate 21 is arranged in the circular ring 1213 and is tightly attached to the water-blocking baffle 121, and the installation is stable and reliable. An upwardly extending limiting column is provided at the center of the water diversion plate 21. A limiting hole consistent with the cross-section of the limiting column is provided in the middle of the toothed disc 22, and the toothed disc 22 is installed on the limiting column of the water diversion disc 21 through the limiting hole. The water-blocking baffle 121 is also provided with a card 1214 pointing to the teeth of the toothed disc 22, which can prevent the toothed disc 22 from reversing.

[0047] The switching drive assembly 3 is mounted within the housing 1 and includes an instant reset member 31 and a switching lever 32. One end of the switching lever 32 is connected to and driven by the instant reset member 31, while the other end extends into the water inlet channel 12 and points toward the switching structure. The instant reset member 31 is connected to the water inlet channel 12. When water enters the water inlet channel 12, the water pressure drives the instant reset member 31 and moves the switching lever 32 away from the water path switching assembly 2. When the water is turned off, the water pressure disappears, and the instant reset member 31 resets the switching lever 32, controlling the water path switching assembly 2 and achieving a single water path switching operation.

[0048] In one embodiment, a switching rod telescopic hole 1215 and a water-passing hole 1216 are provided on the periphery of the water inlet channel 12. The instant reset member 31 includes a switching cylinder 311, a switching block 312, a switching block 313 and a switching spring, wherein one end of the switching cylinder 311 is installed on the periphery of the water inlet channel 12 and covers the switching rod telescopic hole 1215 and the water-passing hole 1216. The switching block 312 is slidably installed in the switching cylinder 311. The switching block 313 is arranged at the other end of the switching cylinder 311. The switching spring is pre-tightened and arranged between the switching block 312 and the switching block 313. One end of the switching rod 32 is installed on the switching block 312, and the other end passes through the switching rod telescopic hole 1215 and is provided with an arc-shaped pushing head pointing to the switching structure. When water enters the water inlet channel 12, the water enters the switching cylinder 311 through the water hole 1216 and hydraulically squeezes the switching block 312, causing the switching block 312 to retract, while also driving the switching rod 32 to retract. Preferably, a Y-shaped sealing ring is provided between the periphery of the switching block 312 and the inner wall of the switching cylinder 311 to improve the reliability of the instant reset element 31.

[0049] When the water is turned off, the switching spring causes the switching block 312 to quickly drain the water through the water hole 1216 and reset, simultaneously driving the switching lever 32 to reset and control the water path switching assembly 2, switching the water path. This allows the user to quickly turn the water back on after turning it off to enjoy a different water flow method. The larger the water hole 1216, the faster the switching block 312 returns to its original position.

[0050] The reset drive assembly 4 is mounted within the housing 1 and includes a delayed reset member 41 and a reset lever 42. One end of the reset lever 42 is connected to and driven by the delayed reset member 41, while the other end extends into the water inlet channel 12 and points toward the reset structure. The delayed reset member 41 is connected to the water inlet channel 12. When water enters the water inlet channel 12, the water pressure drives the delayed reset member 41 and moves the delayed lever away from the water path switching assembly 2. When the water is turned off, the water pressure disappears, and the delayed reset member 41, through a delayed reset action, drives the switching lever 32 to operate the water path switching assembly 2, thereby resetting the water path.

[0051] In one embodiment, a reset rod telescopic hole 1217 is provided around the periphery of the water inlet channel 12. The delayed reset element 41 includes a reset cylinder 411, a reset block 412, a reset stopper 413, and a reset spring. One end of the reset cylinder 411 is mounted around the periphery of the water inlet channel 12 and covers the reset rod telescopic hole 1217. The reset block 412 is slidably mounted within the reset cylinder 411. The reset stopper 413 is disposed at the other end of the reset cylinder 411. The reset spring is preloaded and disposed between the reset block 412 and the reset stopper 413. One end of the reset rod 42 is mounted on the reset block 412, while the other end passes through the reset rod telescopic hole 1217 and is provided with an arc-shaped push head directed toward the switching mechanism. A water seepage groove 421 is provided between the reset rod 42 and the reset rod telescopic hole 1217. The water seepage groove connects the water inlet channel 12 and the reset cylinder 411. When water enters the water inlet channel 12, it enters the reset cylinder 411 through the water seepage groove 421 and hydraulically squeezes the reset block 412, causing the reset block 412 to retract, simultaneously driving the reset rod 42 backward. Preferably, the water seepage groove 421 is a strip-shaped groove formed around the reset rod 42. A Y-shaped sealing ring is provided between the periphery of the reset block 412 and the inner wall of the reset cylinder 411 to enhance the reliability of the delayed reset element 41.

[0052] When the water is turned off, the reset spring causes the reset block 412 to slowly drain the water through the seepage groove and reset the water. This, in turn, causes the switch lever 32 to slowly reset and control the waterway reset assembly, achieving a delayed reset of the waterway. When the user turns the water back on after a certain period of time, the original water flow pattern is restored. The smaller the cross-section of the seepage groove 421, the longer the delay in resetting the switch lever 32.

[0053] In other embodiments, a water outlet device is provided, wherein the housing 1 includes, from top to bottom, a top cover 15, an inner frame 16, a first water outlet panel 17, a second water outlet panel 18, and a bottom cover 19. The water inlet channel 12, the first water outlet channel 13, the second water outlet channel 14, and the water baffle 121 are all arranged on the inner frame 16. The first water outlet panel 17 and the second water outlet panel 18 are installed at the bottom or periphery of the inner frame 16 and are connected to the first water outlet channel 13 and the second water outlet channel 14, respectively. The top cover 15 covers the top of the inner frame 16 and covers the water channel switching assembly 2, the switching drive assembly 3, and the reset drive assembly 4. The top cover 15 is provided with a water inlet joint for docking with the water inlet channel 12, such as a ball head water inlet joint and a seat for installing it. In this embodiment, in order to improve the installation stability of the switching drive assembly 2, a spring for pressing the toothed disc 22 and an end cover of the sealing ring 1213 can also be provided in the top cover 15. The bottom cover 19 covers the bottom of the inner frame 16 , the first water outlet panel 17 and the second water outlet panel 18 .

[0054] The present invention is provided with a switching structure and a reset structure, and provides a switching drive component 3 and a reset drive component 4 that can be reset in time and delayed after the water is turned off, so as to realize automatic switching of the water channel at the moment of turning off the water, and realize automatic switching of the water channel to the initial state after a period of time after turning off the water.

[0055] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
