Abstract
Description
Technical Field
[0001] This utility model relates to the field of faucet technology, specifically a manual and sensor-operated integrated faucet. Background Technology
[0002] In modern buildings and public health facilities, faucets, as key devices for controlling water flow, are widely used in washbasins, kitchens, and other areas of homes, hospitals, shopping malls, and public places. Traditional faucets are usually manually operated, using knobs or push-button mechanisms for on / off control. While simple in structure and low in cost, they require direct human contact during use, easily leading to cross-contamination, especially in high-traffic areas where hygiene risks are particularly prominent. To solve this problem, sensor faucets have emerged. Based on infrared sensing technology or capacitive sensing principles, sensor faucets automatically turn on the water flow when they detect a user's hand approaching and automatically turn it off when the hand leaves, thus achieving contactless water use and improving both convenience and hygiene.
[0003] Chinese patent document "CN216843264U, A manual and sensor integrated kitchen faucet" describes a faucet with a dual valve core structure. One valve core is directly connected to the main water outlet channel of the faucet, while the other valve core is connected to the main water outlet channel of the faucet through a sensor-controlled structure. This allows the faucet to switch between automatic and manual water dispensing modes. However, this faucet has handles on both sides to operate the respective valve cores, resulting in complex water circuit connections and high costs. Utility Model Content

[0012] The beneficial effects of this utility model are:
[0013] The water outlet control unit of this utility model includes a handle, a valve core, a solenoid valve, and a sensor electrically connected to the solenoid valve. The handle is connected to the valve core, which has a first water inlet channel, a second water inlet channel, and a water outlet channel. The first water inlet channel is connected to a first water inlet pipe, which is connected to an external water source. The second water inlet channel is connected to a second water inlet pipe, and the other end of the second water inlet pipe is connected to a three-way valve. The other two ports of the three-way valve are connected to the external water source and the solenoid valve, respectively. The two ends of the water outlet channel are connected to a first water outlet pipe and a second water outlet pipe, respectively. The first water outlet pipe is connected to the other end of the solenoid valve, and the second water outlet pipe is connected to a water outlet bend. When the induction water outlet mode is required, the user only needs to bring their hand close to the sensor. After the sensor detects the signal, it will automatically send an opening command to the solenoid valve. After the solenoid valve opens, the water from the external water source enters the solenoid valve through the three-way valve, then enters the water outlet channel of the valve core through the first water inlet pipe, and then flows through the second water outlet pipe to the water outlet bend and sprays out, realizing automatic water outlet without manual operation. The system allows for switching between manual and sensor-based modes using a single valve core, resulting in a simple, low-cost, and highly reliable design. Even if the handle is damaged, water can still be dispensed via the sensor; conversely, if the sensor fails, manual operation continues, demonstrating excellent redundancy and practicality.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Please refer to Figures 1-6 ;
[0024] A manual and sensor-operated integrated faucet includes a faucet body 1 and a water outlet control unit 3 mounted on the faucet body 1. The faucet body 1 has a water outlet bend 2 at its top. Water is directed into the faucet body 1 by controlling the water outlet control unit 3 and then sprayed out through the water outlet bend 2. The water outlet control unit 3 includes a handle 31, a valve core 32, a solenoid valve 33, and a sensor 34 electrically connected to the solenoid valve 33. The handle 31 is connected to the valve core 32, allowing the user to drive the valve core 32 by moving the handle 31, thus achieving manual water outlet control. The valve core 32 has a first water inlet channel 35, a second water inlet channel 36, and a water outlet channel 37. The first water inlet channel 35 is connected to a first water inlet pipe 35. 1. The first water inlet pipe 351 is connected to an external water source and serves as the main water inlet path in the manual water outlet mode. The second water inlet channel 36 is connected to the second water inlet pipe 361. The other end of the second water inlet pipe 361 is connected to a three-way valve 362. The other two ports of the three-way valve 362 are connected to the external water source and the solenoid valve 33, respectively, thus providing an independent water inlet path for the induction water outlet mode. The two ends of the water outlet channel 37 are connected to the first water outlet pipe 371 and the second water outlet pipe 372, respectively. The first water outlet pipe 371 is connected to the other end of the solenoid valve 33 and is used to introduce water into the water outlet channel 37 in the induction water outlet mode. The second water outlet pipe 372 is connected to the water outlet bend 2 and serves as the final water outlet path for both water outlet modes. When the user selects manual water dispensing, simply operate handle 31 to open valve core 32. Water from the external source flows sequentially through the first inlet pipe 351 and the first inlet channel 35 inside valve core 32 into outlet channel 37, and is then delivered to outlet bend 2 via second outlet pipe 372 before being sprayed out. When the user needs to use the induction water dispensing mode, simply bring your hand close to sensor 34. Sensor 34 detects the signal and automatically sends an opening command to solenoid valve 33. After solenoid valve 33 opens, water from the external source flows through three-way valve 362 into solenoid valve 33, then through the first inlet pipe 351 into outlet channel 37 of valve core 32, and finally through second outlet pipe 372 to outlet bend 2 before being sprayed out, achieving automatic water dispensing without manual operation. This application achieves switching between manual and induction modes using only one valve core 32, resulting in a simple structure, low cost, and high reliability. Even if the handle 31 is damaged, water can still be dispensed through the sensor 34. If the sensor 34 fails, it can still be used manually, which has good redundancy and practicality.
[0025] In this embodiment, a sealing element 21 is snapped into the inner side of the top of the faucet body 1, and the other end of the sealing element 21 extends into the water outlet bend 2. A protruding ring 22 is provided on the inner wall of the top of the faucet body 1, and an annular groove 23 is provided on the outer surface of the sealing element 21 to engage with the protruding ring 22, so that the sealing element 21 can be securely snapped into the faucet body 1 to achieve its fixed installation. The sealing element 21 is provided with a through hole 24 for connecting the second water outlet pipe 372 and the water outlet bend 2. The other end of the second water outlet pipe 372 extends into the through hole 24 and is provided with a connecting ring 25 at the end. The outer wall of the connecting ring 25 is provided with a plurality of sealing ring grooves 26, and a sealing ring 27 is provided in the plurality of sealing ring grooves 26, thereby achieving a tight sealing connection between the second water outlet pipe 372 and the through hole 24 to prevent water leakage. The top outer surface of the sealing element 21 is provided with a plurality of sealing ring grooves 28, and a sealing ring 29 is provided in the plurality of sealing ring grooves 28. The other side of the sealing ring 29 abuts against the inner wall of the water outlet bend 2. When the sealing element 21 is installed in place, the sealing ring 29 will abut against the inner wall of the water outlet bend 2, preventing water from leaking out from the connection gap between the faucet body 1 and the water outlet bend 2.
[0026] In this embodiment, a nozzle 4 is fixedly connected to the end of the water outlet bend 2 away from the faucet body 1. A nozzle 41 is threadedly connected to the water outlet of the nozzle 4. Several protrusions 42 are arranged in a circular array on the outer end face of the nozzle 41. The nozzle 41 can be easily unscrewed manually through the protrusions 42, and other types of nozzles can be replaced without the use of other tools.
[0027] In this embodiment, the bottom end of the faucet body 1 is threadedly connected to a fixing seat 5. The fixing seat 5 has external threads. The faucet body 1 is fixed in the installation position by the fixing seat 5, which makes installation convenient and improves the user experience.
[0028] In this embodiment, the solenoid valve 33 is connected to an external power supply 6, which supplies power to the solenoid valve 33 and the sensor 34.
