Description

Technical Field

[0001] This utility model relates to a faucet. Background Technology

[0002] Pull-out faucets, as a modern kitchen or bathroom appliance, are widely popular due to their flexibility and convenience. Their basic structure typically includes the faucet body, spout, pull-out hose, control valve, and switching device. The faucet body is fixed to the countertop or sink, and the spout is connected to the body via the pull-out hose, allowing users to pull out the spout and adjust the water flow as needed. The control valve regulates the water flow and temperature, while the switching device allows for switching between different water flow modes (such as normal flow, spray mode, etc.). Traditional pull-out faucets are primarily controlled by a mechanical handle, which users rotate or pull to adjust the water flow.

[0003] However, existing pull-out faucets still have some obvious shortcomings in terms of functionality and design. First, most pull-out faucets only support a single mechanical handle control method, requiring users to operate the faucet through physical contact, which is inconvenient in certain scenarios (such as when hands are covered in oil or when a quick start / stop of water flow is needed). In recent years, pull-out faucets controlled by magnetic induction switches or sensor windows have gradually appeared on the market. These products achieve water flow switching through non-contact sensing technology, improving hygiene and ease of operation. However, this design still has significant limitations: its sensing module and the core components of the faucet (such as the solenoid valve) are usually separate structures, with the solenoid valve often located outside the faucet body and connected via additional pipes and wiring. This design not only increases the complexity of undersink installation but also results in scattered components, occupying more space and making installation and maintenance difficult.

[0014] In a preferred embodiment, the seat is fixedly connected to the valve seat, and the faucet body is detachably connected to the seat via a snap fastener.

[0015] In a preferred embodiment, the sensor window is connected to the solenoid valve and the magnetic induction switch via wiring; the faucet also includes a battery box connected to the sensor window; the battery box is sleeved outside the pull-out tube.

[0016] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0017] I. This application provides a faucet, including a faucet body, a pull-out tube, a valve assembly, and a sensing assembly;

[0018] The valve assembly is used to receive cold water and hot water and control the temperature to form a mixed water. The valve assembly is disposed in the faucet body. The valve assembly includes a valve core, a valve seat and a solenoid valve. The valve core and the solenoid valve are respectively connected to the valve seat. The valve seat includes a first water outlet channel, a second water outlet channel and a confluence channel. The valve core is used to control the mixed water to connect to the first water outlet channel or the second water outlet channel.

[0020] Second, the connecting joint is close to the guide tube body. When the pull tube is not pulled out, the magnetic component corresponds to or is offset from the magnetic induction switch, and the magnetic component is located inside the guide tube body. Since the magnetic induction switch is close to the guide tube body, there will be no situation where the two are too far apart or the position between them is unstable, resulting in poor sensing.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1-11 A faucet includes a faucet body 1, a pull-out tube 2, a valve assembly 3, and a sensor assembly 4. The faucet body 1 includes a faucet seat 11 and a faucet bend 12. The faucet seat 11 has a three-way pipe structure, including a vertical tube 111 and a horizontal tube 112. One end of the horizontal tube 112 is connected to the side wall of the vertical tube 111, and the horizontal tube 112 communicates with the vertical tube 111. The faucet bend 12 is rotatably connected to the upper end of the vertical tube 111.

[0035] The valve assembly 3 is used to receive cold water and hot water and control the temperature to form a mixed water. The valve assembly 3 is disposed inside the faucet body 1. The valve assembly 3 includes a valve core 31, a valve seat 32, and a solenoid valve 33. The valve core 31 and the solenoid valve 33 are respectively connected to the valve seat 32. The valve core 31 includes a first valve outlet 311 and a second valve outlet 312. The valve core 31 is used to control the mixed water to connect to the first valve outlet 311 or the second valve outlet 312. The valve seat 32 includes a first water outlet channel 321, a second water outlet channel 322, and a confluence channel 323. The inlets of the first water outlet channel 321 and the second water outlet channel 322 are respectively connected to the first valve outlet 311 and the second valve outlet 312. The confluence channel 323 is connected to the first water outlet channel 321 and the second water outlet channel 322. The solenoid valve 33 is used to control the opening and closing of the second water outlet channel 322. The pull-out tube 2 is connected to the confluence channel 323. The valve seat 32 further includes a first water inlet channel 324 and a second water inlet channel 325, which are respectively connected to hot water and cold water to connect to the valve core 31. The valve core 31 is a two-inlet, two-outlet temperature-regulating switching valve core 31. The valve core 31 includes a valve shaft 313, which is connected to a handle 34. By rotating the handle 34, the temperature of the mixed water can be controlled. By turning the handle 34, water can be controlled to flow from the first valve outlet 311 or the second valve outlet 312 of the valve core 31.

[0036] The sensing component 4 includes a magnetic sensing component 414 and a water dispensing sensing component 42. The magnetic sensing component 414 includes a magnetic component 411 and a magnetic induction switch 412. The magnetic component 411 is disposed on the pull-out tube 2. When the pull-out tube 2 moves, the magnetic component 411 can correspond to or deviate from the magnetic induction switch 412 to control the solenoid valve 33. The water dispensing sensing component 42 includes a sensing window 421, which is disposed on the faucet body 1. The sensing window 421 is used to sense the presence of a human body to control the solenoid valve 33 accordingly. In this embodiment, the sensing window 421 is an infrared sensor or the like.

[0037] When controlling the water flow from the pull-out pipe 2 of the faucet, there are three control methods: First, the handle 34 can be directly controlled to cause water to flow from the first valve outlet 311 of the valve core 31. The mixed water connects to the first water outlet channel 321 through the first valve outlet 311, enters the confluence channel 323, enters the pull-out pipe 2, and flows out from the water outlet 21 at the end of the pull-out pipe 2. Second, the pull-out pipe 2 can be directly pulled to cause the magnetic component 411 to deviate from the magnetic induction switch 412. At this time, the solenoid valve 33 is controlled in conjunction to connect the second water outlet channel. At this time, since the second valve outlet 312 of the valve core 31 is connected (previously connected via the handle 34), the mixed water enters the confluence channel 323 through the second water outlet channel and then enters the pull-out pipe 2; thirdly, the user waves their hand in front of the sensor window 421, causing the solenoid valve 33 to be linked and connected, thus connecting the second water outlet channel. At this time, since the second valve outlet 312 of the valve core 31 is connected (previously connected via the handle 34), the mixed water enters the confluence channel 323 through the second water outlet channel and then enters the pull-out pipe 2. This application integrates three control methods and concentrates the solenoid valve 33 within the faucet body 1, resulting in a more compact overall design and multiple control methods.

[0038] In this embodiment, the valve seat 32 is disposed within the vertical tube 111, and the valve core 31 can be inserted from the horizontal tube 112 to correspondingly connect with the valve seat 32. The solenoid valve 33 is connected to the upper end of the valve seat 32 to correspondingly be disposed within the vertical tube 111. The valve seat 32 includes a clearance channel 326 through which the pull tube 2 passes.

[0039] The faucet also includes a mounting component 5; the mounting component 5 includes a mounting base 51 and an undermount mounting component 525. The mounting base 51 includes a base body 511 and a guide tube 512. The undermount mounting component 525 is connected to the base body 511. The guide tube 512 defines a pull-out channel 5121. The base body 511 is connected to the faucet body 1. The pull-out tube 2 passes through the pull-out channel 5121. The magnetic induction switch 412 is disposed on the undermount mounting component 525 to approach or abut the guide tube 512. Specifically, the under-seat mounting assembly 525 includes a slide 521, two support arms 522, a transmission component 523, a guide component 524, and a connecting joint 525; the transmission component 523 connects the seat body 511 and the slide 521, and the transmission component 523 is operably mounted on the seat body 511 so as to drive the slide 521 to slide on the guide component 524; the two support arms 522 are respectively mounted on both sides of the slide 521; the guide component 524 is fixedly connected between the seat body 511 and the connecting joint 525, and the magnetic induction switch 412 is mounted on the connecting joint 525; wherein, the connecting joint 525 is close to or abuts against the guide tube 512. In this embodiment, the transmission component 523 is a bolt, the head 5231 of which is rotatably mounted on the seat 511. The slide 521 is threadedly connected to the shank 5232 of the bolt. The guide component 524 includes two guide rods 5241, the two ends of which are fixedly connected to the seat 511 and the connecting joint 525, respectively. The slide 521 is slidably mounted on the two guide rods 5241. When the head 5231 of the bolt is driven to rotate by a tool (screwdriver), the slide 521 can only move along the shank 5232 of the bolt due to the guiding effect of the two guide rods 5241. The two support arms 522 are rotatably connected to both sides of the slide 521. The rotation point of the support arm 522 is offset from the middle position of the sliding point. Therefore, the first end of the support arm 522 is higher than the second end in its natural state. When the seat 511 is placed on the table, the under-table mounting assembly 525 passes through the mounting hole on the table and is driven by a tool to rotate the bolt, causing the slide 521 to move upward to abut against the lower side of the table. At this time, the first end of the support arm 522 abuts against the lower side of the table, and the support arm 522 rotates until the second end also abuts against the lower side of the table.The connecting joint 525 is close to the guide tube 512. When the pull-out tube 2 is not pulled out, the magnetic component 411 corresponds to the magnetic induction switch 412, and the magnetic component 411 is located inside the guide tube 512. Because the magnetic induction switch 412 is close to the guide tube 512, there will be no situation where the two are too far apart or their positions are unstable, resulting in poor sensing. In this embodiment, when the magnetic induction switch 412 corresponds to the magnetic component 411, the solenoid valve 33 is in the closed state, and the pull-out tube 2 does not dispense water. When the two are misaligned, the solenoid valve 33 is in the open state, and the pull-out tube 2 dispenses water. In some simpler alternatives, when the magnetic induction switch 412 and the magnetic component 411 are misaligned, the solenoid valve 33 is in the closed state, and when the two are aligned, the solenoid valve 33 is in the open state. In this embodiment, the bottom of the connecting joint 525 has a groove 5251, and the magnetic induction switch 412 is embedded in the groove 5251.

[0040] In this embodiment, the seat 511 is connected to the valve seat 32, and the clearance channel 326 corresponds to the pull-out channel 5121. The seat 511 and the valve seat 32 are fixedly connected by a screw 327, and the faucet body 1 is detachably connected to the seat 511 by a snap-fit ​​526. During installation, the seat 511 can be connected to the valve seat 32, and then the faucet seat 11 can be connected to the seat 511 by the snap-fit ​​526, which is convenient to install and has a high degree of integration.

[0041] In this embodiment, the sensing window 421 is connected to the solenoid valve 33 and the magnetic induction switch 412 via wiring. The faucet also includes a battery box 6, which is connected to the sensing window 421. The battery box 6 is sleeved on the pull-out tube 2 and acts as a counterweight, which can drive the pull-out tube 2 back to its original position. A controller is installed inside the sensing window 421. The controller is connected to the solenoid valve 33, the magnetic induction switch 412, the sensing window 421, and the battery box 6, so as to receive the sensing signals from the magnetic induction switch 412 and the sensing window 421 to control the solenoid valve 33.

[0042] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
