Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen and bathroom appliances, specifically relating to a smart pull-out integrated water purifier faucet device. Background Technology

[0002] In the kitchen and bathroom appliance sector, especially in the kitchen sink area, users' needs for water functions are becoming increasingly diverse. They not only require regular hot and cold tap water for washing, but also filtered water that can be drunk directly. Currently, the common practice is to install two separate faucets on the sink: one for supplying a mixture of hot and cold tap water, and the other specifically connected to a water filtration system for supplying purified water. While this separate layout achieves functional differentiation, it also brings significant inconvenience. Users need to switch between two different faucets when using different water sources, which is not a smooth operation. This is especially true in scenarios where frequent switching between two water sources is required (such as directly using purified water for drinking after washing food), making the operation cumbersome and reducing convenience and efficiency.

[0003] Besides the operational inconvenience, installing two separate faucets significantly occupies the limited countertop space. The sink area typically also needs to accommodate other items such as soap dispensers and drain baskets; the dual faucet configuration makes the countertop layout even more cramped and visually less clean and aesthetically pleasing. For modern kitchens that prioritize space utilization and minimalist design, this space occupation is a significant drawback. Users expect more integrated solutions to free up valuable countertop space.

[0004] Integrating water purification functionality into a single traditional faucet has been a long-standing goal. However, accommodating two independent water systems (tap water and purified water) within a single faucet body while ensuring no cross-contamination presents significant structural design challenges. Traditional faucets have limited internal space, with valve cores, handles, and water pipes already occupying most of the space. Adding an extra purified water channel and a mechanism to control its flow requires not only an extremely compact layout but also stringent requirements for sealing. Any leakage or cross-contamination between the water systems will lead to contamination of the purified water or mixing of tap water with the purified water, severely impacting water safety and quality. Therefore, reliably achieving physically isolated parallel water systems within a limited space is the core technological hurdle facing integration.

[0005] Furthermore, conveniently switching between the two water sources is also a challenge. If traditional mechanical handles or knobs are used to control the flow of purified water, users typically need to perform additional actions, different from those used to control the temperature of the mixed tap water, such as rotating another handle or pressing a button. This method of operation differs from the user's accustomed mode of adjusting water temperature and flow through a single faucet, increasing the learning curve and operational complexity, and failing to achieve a truly intuitive and seamless switching experience. Summary of the Invention

[0006] This utility model provides a smart pull-out integrated water purifier faucet device, which integrates dual water channels and intelligent touch control to achieve multi-mode switching between purified water and hot / cold tap water from a single faucet.

[0020] like Figures 1-6As shown, this utility model provides a smart pull-out integrated water purifier faucet device, including: a faucet body 1; an electronic touch button 2, which is embedded in a fixing seat 17 of the faucet body 1; a ceramic valve core, which is fixed in the faucet body 1, and the inlet end of the ceramic valve core is connected to a cold water inlet pipe 6 and a hot water inlet pipe 7; a solenoid valve control module, which includes a solenoid valve control box assembly 16, the inlet end of the solenoid valve control box assembly 16 is connected to the outlet end of the water purifier filter 3, and the solenoid valve control box assembly 16 is electrically connected to the electronic touch button 2; and a pipe-in-pipe shower head component, which includes a pipe-in-pipe connecting pipe 4, which passes through the faucet body. 1. The pipe-in-pipe connecting pipe 4 has a double-layer sleeve structure: the inner pipe is the first water channel, located in the center, and connected to the water outlet of the solenoid valve control box assembly 16; the annular gap between the inner pipe and the outer pipe forms the second water channel, which is connected to the water outlet of the ceramic valve core; the shower head 13 is fixedly connected to the pipe-in-pipe connecting pipe 4 and movably connected to the faucet body 1 so as to be pulled, moved and rotated, wherein the center of the shower head 13 is provided with a clean water outlet hole, which is connected to the first water channel; a tap water outlet hole is provided around the periphery of the shower head 13, surrounding the clean water outlet hole, and the tap water outlet hole is connected to the second water channel.

[0021] In the above embodiment, the faucet body 1 is fixedly installed on the kitchen sink countertop. The mounting base of the faucet body 1 is located on the lower side of the faucet body 1, with a pre-reserved groove. An electronic touch button 2 is installed in the groove. This button uses a capacitive touch sensor; a light touch by the user sends a signal. The ceramic valve core is a hot and cold mixing valve core, fixed inside the faucet body 1. Its inlet end is connected to the cold water inlet pipe 6 and the hot water inlet pipe 7 via threads to achieve hot and cold water mixing regulation. The outlet end is connected to the mixing water connector 502 of the connecting joint 5 of the pipe-in-pipe connecting pipe 4 via the tap water mixing pipe 11. The solenoid valve control module includes a solenoid valve control box assembly 16. Its inlet end is connected to the outlet end of the water filter 3 via a first quick-connect plug 8, and the outlet end is connected to the water filter connector 501 of the connecting joint 5 of the pipe-in-pipe connecting pipe 4 via a second quick-connect plug 9 and a water filter hose 15. The solenoid valve control box assembly 16 is electrically connected to the electronic touch button 2, receiving touch signals to control the flow of purified water. The pipe-in-pipe connecting pipe 4 has a double-layer sleeve structure, passing through the inside of the faucet body 1. The inner pipe forms the first water channel, which is connected to the water purification connector 501 of the connecting joint 5. The annular gap between the inner and outer pipes forms the second water channel, which is connected to the mixing water connector 502 of the connecting joint 5. The shower head 13 is threaded to the end of the pipe-in-pipe connecting pipe 4, and only contacts the upper end of the faucet body 1, without being fixedly connected, allowing it to be pulled, moved, and rotated. A counterweight 14 is provided on the pipe-in-pipe connecting pipe 4 to facilitate its return to its original position after being pulled out. A water purification outlet is opened in the center of the shower head 13, which is connected to the first water channel. Tap water outlets, including aerated water outlets and shower water outlets, are arranged around the water purification outlet, and both are connected to the second water channel.

[0022] Compared to the closest existing technology, traditional kitchens require two separate faucets: one for mixing hot and cold tap water, and the other dedicated to purified water supply. This necessitates frequent switching between the two, taking up countertop space and complicating the process. This embodiment integrates physically isolated dual water paths into a single faucet. An electronic touch button 2 controls the purified water supply with a single touch, and the 13-zone showerhead design supports seamless switching between hot and cold tap water rinsing and purified drinking water. No additional faucet is needed, saving space and simplifying operation. Furthermore, the pull-out and rotating function expands its usability, a level of integration and convenience that existing separate faucets cannot achieve.

[0023] In one specific embodiment, the electronic touch button 2 includes a button piece, a limiting rib, and a touch sensor circuit; the button piece is assembled to the fixing base 17 from the outside to the inside and is positioned and fixed by the limiting rib; the signal input terminal of the solenoid valve control box assembly 16 is connected to the touch sensor circuit through a wire.

[0024] In the above embodiment, for example, the button piece can be made of tempered glass or acrylic material with a thickness of 2 mm. The fixing base 17 is located on the lower side of the faucet body 1, with a pre-reserved circular groove, for example, 18.2 mm in diameter and 3 mm deep. The annular limiting rib has an inner diameter of 16 mm, an outer diameter of 18 mm, and a height of 2.5 mm. During assembly, the circular button piece is axially pressed into the groove, and the inner and outer circumferential surfaces of the annular limiting rib constrain the radial displacement of the button piece. The surface of the circular button piece is flush with the outer surface of the faucet body 1, without protrusions or depressions. This structure ensures that the button piece does not shift or loosen under frequent touches, and the annular limiting rib provides uniform circumferential constraint. The circuit board for the touch sensor circuit can be a circular module with a diameter of 15 mm and a thickness of 1 mm, which is fitted and fixed to the inner side of the button piece. The signal wire can be a four-core shielded wire, with one end soldered to the output terminal of the circuit board, and the other end passing through a conduit pre-embedded inside the faucet body 1 to connect to the signal input port of the solenoid valve control box. The signal wire is loosely bent inside the conduit to prevent it from being pulled when the faucet is pulled out. This implementation method, through the mechanical constraint of the limiting ribs and the direct circuit connection design, ensures the long-term stability of the electronic touch button 2.

[0025] In one specific embodiment, the solenoid valve control module further includes a DC battery box 10, the output terminal of which is electrically connected to the power input terminal of the solenoid valve control box assembly 16 to provide power to the solenoid valve control box assembly 16; the control signal output terminal of the solenoid valve control box assembly 16 is connected to the coil drive terminal of the solenoid valve to control the opening and closing of the solenoid valve by switching the power on and off. A light-emitting sheet is provided around the electronic touch button 2. The light-emitting sheet is connected to the power output terminal of the solenoid valve control box assembly 16 through a wire, and the solenoid valve control box assembly 16 controls its lighting and turning off synchronously according to the touch signal.

[0026] In the above embodiment, exemplarily, the DC battery box 10 is disposed outside the solenoid valve control box assembly 16. The solenoid valve control box assembly 16 has a built-in voltage regulator circuit that converts the battery voltage into the operating voltage. The control signal output terminal is connected to the solenoid valve coil drive terminal. When the touch sensor is triggered, the solenoid valve control box assembly drives the solenoid valve core to realize the opening and closing of the water circuit. The DC battery box door is equipped with a silicone sealing ring, and the waterproof rating reaches IPX4.

[0027] For example, the light-emitting sheet can be a 5mm diameter SMD LED patch, emitting blue light, soldered onto a 0.8mm thick circuit board. The light-emitting sheet is embedded in an annular groove around the circular button piece, with an inner diameter of 18.5mm, an outer diameter of 24.5mm, and a depth of 2mm. The groove is distributed around the circular button piece and connected to the auxiliary power output of the solenoid valve control box assembly via wires. A driver chip is installed within the solenoid valve control box assembly; when a touch signal is validly triggered, the LED lights up synchronously. After the solenoid valve closes, the driver chip cuts off the LED power. A constantly lit light-emitting sheet after touch indicates that the water purification mode is on; touching it again turns it off and shuts off the water flow.

[0028] In one specific embodiment, the tap water outlet of the shower head 13 includes an aerated water outlet and a shower water outlet, which are distributed circumferentially around the purified water outlet.

[0029] In the above embodiment, for example, the central water outlet hole of the shower head 13 can have a diameter of 3.5 mm and a depth of 8 mm. The tap water outlet holes include two types: 20 aerated water outlet holes with a diameter of 0.5 mm and a depth of 5 mm; and 10 shower water outlet holes with a diameter of 1 mm and a depth of 6 mm. The inner walls of all holes are mirror-polished.

[0030] The aerated water holes and shower water holes are arranged concentrically around the water purification holes. The water purification holes are located at the center, the aerated water holes are distributed on a 20 mm diameter circle, and the shower water holes are distributed on a 30 mm diameter circle. The two types of tap water holes are arranged alternately, with a minimum hole spacing of 3 mm. The shower head 13 end face has an annular guide groove, 2 mm wide and 1 mm deep, connecting all tap water outlet holes. This layout ensures that the purified water flows vertically, the aerated water forms a gentle umbrella-shaped flow, and the shower water forms a jet-like rinsing flow. This implementation achieves independent water output for 13 functions in a single shower head through differentiated aperture and distribution design. The central water purification hole ensures the purity of the drinking water, while the peripheral dual-mode hole group meets the needs of cleaning and rinsing. The staggered layout avoids mutual interference of water flow, and the sealed structure ensures the reliability of water path isolation.

[0031] In one specific embodiment, the valve core base of the ceramic valve core is fixedly disposed inside the faucet body 1, the cold water inlet pipe 6 and the hot water inlet pipe 7 are respectively threadedly connected and fixed to the valve core base, and the mechanical handle 12 drives the ceramic valve core through the valve stem.

[0032] In the above embodiment, for example, the valve core base is fixed to the bottom of the inner cavity of the faucet body 1 by three M4 stainless steel countersunk nuts. A hot and cold water mixing chamber is formed in the center of the valve core base, and two O-ring sealing structures are provided at the bottom of the valve core base, which are interference-fitted with the inner wall of the faucet body 1. During installation, the sealing rings are first embedded into the grooves, then the base is vertically pressed into the faucet body 1, and finally the fixing nuts are screwed in from the outside.

[0033] For example, the hot and cold water inlet pipes can be made of 304 stainless steel braided tubing, with M10×1 external threads machined at the pipe ends. Threaded holes with M10×1 internal threads are symmetrically opened on both sides of the valve core base. During assembly, a sealing ring is used to seal the rear end of the inlet pipe thread, which is then screwed into the threaded hole of the base.

[0034] In one specific embodiment, the inlet end of the solenoid valve control box assembly 16 is connected to the outlet end of the water filter 3 via a first quick-connect plug 8; the outlet end of the solenoid valve control box assembly 16 is connected to the water connector 501 of the connecting joint 5 of the pipe-in-pipe connecting pipe 4 via a second quick-connect plug 9, and is connected to the first water passage.

[0035] In the above embodiment, the first quick-connect plug 8 can be a G1 / 4 brass quick-connect fitting, with its male end connected to the water outlet hose of the water filter 3 via a thread, and its female end inserted into the side inlet of the solenoid valve control box assembly 16. The second quick-connect plug 9 can be of the same G1 / 4 specification, with its male end connected to the outlet of the solenoid valve control box assembly 16, and its female end connected to the water hose 15 connected to the water filter connector 501. This embodiment achieves rapid assembly and reliable sealing of the water purification pipeline through standardized quick-connect plugs.

[0036] In one specific embodiment, the water purification filter 3 is any one of an ultrafiltration filter, an activated carbon filter, or an RO reverse osmosis filter.

[0037] In the above embodiment, the ultrafiltration filter can be a hollow fiber membrane module with a pore size of 0.01 micrometers and a filtration area of ​​0.8-1.2 square meters. The outer shell can be made of 304 stainless steel, with a height of 300 mm and a diameter of 90 mm, and is filled with polysulfone membrane fibers. It is fixed to the side wall of the cabinet below the sink and connected to the inlet of the solenoid valve control box assembly via a G1 / 4 quick-connect plug. Operating process: Tap water enters through the bottom inlet, is filtered by the membrane fibers, and then flows out through the top outlet. Impurities are periodically discharged through a side drain valve (manual knob type).

[0038] Activated carbon filter configuration: The activated carbon filter can use sintered activated carbon rod components, with a diameter of 60 mm, a length of 250 mm, and an iodine value ≥1000 mg / g. The outer shell can be made of food-grade ABS plastic, with 316 stainless steel end caps at both ends, and quick-connect interfaces connected through a center opening on the end caps. It is installed parallel to the ultrafiltration filter in a cabinet, with the inlet end connected to the pre-filter and the outlet end connected to the solenoid valve control box assembly via a hose. Operating process: When water flows through the micropores inside the carbon rod, the residual chlorine adsorption rate is ≥99%, and organic matter is retained through physical adsorption.

[0039] RO Reverse Osmosis Filter Configuration: The RO reverse osmosis filter can use polyamide composite membrane elements with a desalination rate ≥98% and a membrane area of ​​1.5 square meters. The system includes a pre-filter (PP cotton filter), a booster pump, and a pressure storage tank. The overall dimensions are 400 mm × 250 mm × 400 mm, and it is fixed to the bottom of a cabinet. Operating Process: Tap water undergoes three stages of pretreatment before entering the RO membrane. The purified water is stored in the pressure tank, and the concentrated water is discharged through a wastewater ratio (1.5:1). The inlet of the solenoid valve control box assembly is connected to the outlet of the pressure tank.

[0040] This implementation method utilizes modular filter configurations to adapt to different water purification needs. Ultrafiltration ensures effective physical sterilization, activated carbon efficiently adsorbs chemical pollutants, and RO achieves deep desalination. Quick-connect interfaces with standardized specifications simplify the assembly process, and actual test data shows that each filter meets drinking water safety standards under its calibrated parameters.
