Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures technology, and in particular to a multifunctional water outlet device with a built-in pure water switch channel. Background Technology

[0002] Existing faucets and showerheads typically have one outlet for tap water, but in many cases, a water purifier faucet is also needed near these outlets to provide purified water. These two separately installed water outlets take up considerable space and are inconvenient to operate, use, and clean, making them less user-friendly. To address this issue, a combined water outlet system has been designed, integrating both tap water and purified water outlets for easier access.

[0003] For example, in Chinese invention application CN109869505A, entitled "A Dual-Channel Faucet," the faucet body is disclosed to have a first inlet channel and a first outlet channel connected within it. A second inlet channel is located within the first inlet channel, with a water passage gap between them. A second outlet channel is also present within the faucet body, and the second inlet channel and the second outlet channel are connected. Both the outlet of the first outlet channel and the outlet of the second outlet channel are located at the bottom of the faucet body. By simultaneously setting a second inlet channel and a second outlet channel within the faucet, two independent channels are formed: one for tap water and the other for purified water, ensuring that the purified water is not contaminated by the tap water. However, its tap water channel structure is relatively simple, making it impossible to add another water path within the tap water channel, thus failing to achieve a dual-channel, dual-splash tap water output mode, requiring further improvement. Utility Model Content

[0004] To address the aforementioned issues, the present invention aims to provide a multifunctional water outlet device with a built-in pure water switch channel. This device integrates pure water and tap water outlets, allowing the pure water outlet to be independently switched on and off. The tap water outlet section has two independent water passages, one of which can also be independently switched on and off, facilitating the creation of two different water outlet effects and simplifying its use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional water outlet device with a built-in pure water switch channel includes a housing, a tap water inner core tube, and a pure water inner core tube. The tap water inner core tube is sleeved in the housing, and the pure water inner core tube is sleeved inside the tap water inner core tube. The tap water inner core tube and the pure water inner core tube are connected to the input end of a water distribution valve body. The water distribution valve body is provided with a pure water switch mechanism and a tap water diversion and outlet mechanism. The pure water switch mechanism is connected to a switch button for controlling the opening and closing of the pure water supply channel. The tap water diversion and outlet mechanism has two independent water passages connected to the tap water inner core tube. The first water passage is normally open, and the second water passage can be rotated to open or close. The outlet panel connected to the output ends of the two water passages is located on the side of the housing. The pure water output pipe in the pure water switch mechanism is independently located in the center of the outlet panel.

[0007] Furthermore, the water distribution valve body is provided with a connecting valve seat, which is provided with a purified water channel and a tap water channel. The tap water distribution mechanism includes a water distribution sleeve, a water sealing plate, a water distribution switching plate, and a switch knob housing. The water distribution sleeve is snapped onto the connecting valve seat. The water distribution sleeve is provided with a central connecting pipe, a first water passage, and a second water passage. The water distribution switching plate is sleeved in the connecting valve seat. The water outlet panel is provided with a purified water outlet central pipe, a first water outlet screen, and a second water outlet annular groove. The purified water outlet central pipe and the first water outlet screen are normally open and connected to the central connecting pipe and the first water passage, respectively. The water distribution sleeve, being sleeved on the connecting valve seat, can drive the water sealing plate and the water outlet panel to rotate coaxially relative to the water distribution switching plate. When the water distribution sleeve rotates, it controls the opening or closing of the second water passage. When opened, water flows out from the second water outlet annular groove.

[0008] Furthermore, the switch knob housing connects the water outlet panel and the water distribution sleeve together. The water sealing plate is disposed in the water distribution sleeve. The water sealing plate has a central through hole, a first water through hole, and a second water through hole corresponding to the central connecting pipe, the first water through channel, and the second water through channel, respectively. The switch knob housing drives the water distribution sleeve, the water sealing plate, and the water outlet panel to rotate together relative to the water distribution switching plate to open or close the second water passage.

[0009] Furthermore, the water distribution switching plate is axially and vertically mounted in the connecting ring of the connecting valve seat. The water distribution switching plate is provided with a central sleeve and a water passage notch, and the central connecting pipe passes through the central sleeve.

[0010] Furthermore, the outer cylinder of the central sleeve is provided with a guide bar, and the connecting ring is provided with a guide groove to guide the guide bar to slide up and down.

[0011] Furthermore, the water distribution sleeve is provided with a guide block corresponding to the position of the water passage notch, and a first spring is provided between the connecting valve seat and the water distribution switching plate; when the water distribution sleeve rotates, it pushes the water distribution switching plate to move up and down along the axial direction of the guide block.

[0012] Furthermore, the water distribution valve body is provided with a rotation limiting groove, and the water distribution sleeve is provided with a corresponding rotation limiting protrusion.

[0013] Furthermore, the pure water switch mechanism includes a water distribution plug, a switch valve stem, a second spring, a button sleeve, a button rotor rod, a button top pin, and a button rotor. Each time the switch button is pressed, it controls the pure water supply channel between the switch valve stem and the water distribution plug to open or close once.

[0014] Furthermore, the water divider is located in the water divider valve body. The water divider has a pure water inlet hole connected to the output end of the pure water inner core tube. The pure water inlet hole is then connected to the pure water channel through a pure water corner hole. The switch valve rod passes through the pure water inlet hole and moves back and forth when the switch button is pressed to open or close the pure water supply channel. The switch valve rod is provided with a sealing ring that dynamically seals with the input port of the pure water inlet hole.

[0015] Furthermore, the switch button includes a button cover, a button base, and a third spring. One end of the button base is hinged to the end of the water distribution valve body, and one end of the button base is provided with an elastic hook. The button base pushes the switch valve rod to reciprocate through the button sleeve, the button rotor rod, the button top pin, and the button rotor.

[0016] This utility model has the following beneficial effects:

[0017] This utility model incorporates a purified water switch mechanism and a tap water dispensing mechanism, integrating the purified water outlet pipe, the dual tap water outlet channels, and their corresponding two control switches into the water dispensing device. Both purified water and tap water dispensing can be independently switched on and off on the dispensing device. The overall structure is compact and small, and the dual tap water outlet channels provide two different water dispensing effects, making it convenient to use.

[0018] The water dispensing mechanism of this utility model is equipped with a water dispensing sleeve, a water sealing plate, a water dispensing switching plate, and a switch knob shell. The water dispensing sleeve can drive the water sealing plate and the water dispensing panel to rotate coaxially relative to the water dispensing switching plate. By rotating, the second water passage can be opened or closed to achieve two water dispensing effects. Its structure is unique and ingenious.

[0019] This utility model of a pure water switch mechanism includes a water distribution plug, a switch valve stem, a second spring, a button sleeve, a button rotor rod, a button top pin, and a button rotor. This mechanism can effectively press the switch valve stem to move back and forth, thereby opening or closing the pure water supply channel. The design is ingenious, the switch is easy to press and use, and it is convenient to independently control the pure water supply channel. The pure water supply channel is isolated from the tap water supply channel to ensure that it is not contaminated. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0033] See Figure 1-11 As shown, a multi-functional water outlet device with a built-in pure water switch channel includes a housing 1, a tap water inner core tube 2, and a pure water inner core tube 3. The tap water inner core tube 2 is sleeved in the housing 1, and a leak-proof sealing ring is provided between the tap water inner core tube 2 and the housing 1. The pure water inner core tube 3 is sleeved in the tap water inner core tube 2. The tap water inner core tube 2 and the pure water inner core tube 3 are sealed and connected to the input end of the water distribution valve body 4. The water distribution valve body 4 is provided with a pure water switch mechanism 5 and a tap water diversion and outlet mechanism 6. The pure water switch mechanism 5 is connected to a switch button 7 for controlling the opening and closing of the pure water supply channel. The tap water diversion and outlet mechanism 6 has two independent water passages connected to the tap water inner core tube 2. The first water passage is normally open, and the second water passage can be rotated to open or close. The outlet panel 8 connected to the output ends of the two water passages is located on the side of the housing 1. The pure water output pipe in the pure water switch mechanism 5 is independently located in the center of the outlet panel 8.

[0034] The water distribution valve body 4 has a connecting valve seat 41 in the middle. The connecting valve seat 41 has a pure water channel 411 and a tap water channel 412, which are respectively connected to the pure water inner core tube 3 and the tap water inner core tube 2. The tap water distribution mechanism 6 includes a water distribution sleeve 61, a water sealing plate 62, a water distribution switching plate 63, and a switch knob housing 64. The water distribution sleeve 61 is rotatably and sealingly engaged with the connecting valve seat 41. The water distribution sleeve 61 has a central connecting pipe 611, a first water passage 612, and a second water passage 613. The water distribution switching plate 63 is sleeved in the connecting valve seat 41. The water outlet panel 8 is provided with a pure water outlet center pipe 81, a first water outlet mesh plate 82, and a second water outlet annular groove 83. The pure water outlet center pipe 81 and the first water outlet mesh plate 82 are normally open and connected to the central connecting pipe 611 and the first water passage 612, respectively. The water distribution sleeve 61 is provided on the connecting valve seat 41 and can drive the water sealing plate 62 and the water outlet panel 8 to rotate coaxially relative to the water distribution switching plate 63. When the water distribution sleeve 61 rotates, it controls the second water passage 613 to open or close. After the second water passage 613 is opened, water flows out from the second water outlet annular groove 83. The switch knob housing 64 connects the water outlet panel 8 and the water distribution sleeve 61 together. Each connection point is equipped with a leak-proof sealing ring. The water sealing plate 62 is located within the water distribution sleeve 61. The water sealing plate 62 has a central through hole 621, a first water through hole 622, and a second water through hole 623, corresponding to the central connecting pipe 611, the first water passage 612, and the second water passage 613, respectively. The switch knob housing 64 drives the water distribution sleeve 61, the water sealing plate 62, and the water outlet panel 8 to rotate relative to the water distribution switching plate 63, opening or closing the second water passage. The water distribution switching plate 63 is axially liftable and fits into the connecting ring 413 in the connecting valve seat 41. The water distribution switching plate 63 has a central sleeve 631 and a water passage notch 632, and the central connecting pipe 611 passes through the central sleeve 631. The outer cylinder of the central sleeve 631 is provided with a guide bar 633, and the connecting ring 413 is provided with a guide groove 414 to guide the guide bar 633 to slide up and down. The water distribution sleeve 61 is provided with a guide inclined block 614 corresponding to the position of the water passage notch 632. A first spring 65 is provided between the connecting valve seat 41 and the water distribution switching plate 63. The first spring 65 is used to push the water distribution switching plate 63 down to block the second water passage 623, so that the second water passage is closed. When the water distribution sleeve 61 rotates, it pushes the water distribution switching plate 63 to overcome the pressure of the first spring 65 and rise axially along the guide inclined block 614. After the water distribution switching plate 63 rises, it no longer blocks the second water passage 623, and the water flows through the second water passage 623 and the second water passage 613 to the second water outlet ring groove 83 and out.The water distribution valve body 4 is provided with a rotation limiting groove 42, and the water distribution sleeve 61 is provided with a corresponding rotation limiting protrusion 615, which controls the rotation angle between the water distribution sleeve 61 and the water distribution switching plate 63 to ensure the accurate opening or closing of the second water passage.

Each press of the switch button 7 controls the opening or closing of the purified water supply channel between the switch valve stem 52 and the water distribution plug 51. The water distribution plug 51 is located in the water distribution valve body 4. The water distribution plug 51 has a purified water inlet hole 511 connected to the output end of the purified water inner core tube 3. The purified water inlet hole 511 is then connected to the purified water channel 411 through a purified water corner hole 512. The switch valve stem 52 passes through the purified water inlet hole 511 and moves back and forth when the switch button 7 is pressed, opening or closing the purified water supply channel. The switch valve stem 52 is provided with a sealing ring 58 that dynamically seals with the input port of the purified water inlet hole 511. The switch button 7 includes a button cover 71, a button base 72, and a third spring 73. One end of the button base 72 is hinged to the end of the water distribution valve body 4. One end of the button base 72 is provided with an elastic hook. The button base 72 pushes the switch valve rod 52 to reciprocate through the button sleeve 54, the button rotor rod 55, the button top pin 56, and the button rotor 57.

[0036] In use, this multi-functional water outlet device connects to the water outlet of a faucet equipped with an internal purified water pipe. The faucet contains a main switch. When purified water is needed, pressing the switch button 7 will output purified water from the purified water outlet center pipe 81. See the water outlet diagram. Figure 3 When the main switch in the faucet is turned on (the second water circuit is closed by default), water flows directly from the holes in the first water outlet screen 82, which is the shower head output mode. See the water outlet diagram. Figure 4 Then turn the switch knob 64 to open the second water passage. The second water flows out from the second outlet ring groove 83. The water droplets from the two outlets collide to form icicles. See the water outlet diagram. Figure 5 .
