Description

Technical Field

[0001] This utility model relates to a faucet that facilitates switching of water outlet modes. Background Technology

[0002] Most faucets on the market today only offer three basic water dispensing modes: cold water, hot water, and pure water. However, as living standards improve, faucets need to provide more than just hot and cold water; they also need to offer a wider range of functions for users.

[0003] Existing faucet designs have structural limitations, which restrict the expansion of faucet functions and result in a limited selection of water flow modes and a single water flow function for users. Therefore, there is an urgent need in the market for a faucet with diversified water flow functions to meet the growing user demand. Utility Model Content

[0004] This invention provides a faucet that facilitates switching water outlet modes, effectively solving the aforementioned problems.

[0005] This utility model is implemented as follows:

[0006] A faucet that facilitates switching of water flow modes includes a faucet housing; it also includes a sensing component built into the water outlet of the faucet housing and a control box assembly electrically connected to the sensing component to switch the faucet's water flow modes.

[0007] The sensing components include a first sensor located on the bottom surface of the faucet housing's water outlet, a second sensor located on the left and right sides of the faucet housing's water outlet, and a third sensor. Each sensor can identify and collect the distance of a hand approaching the user. When the distance is lower than the sensing threshold, each sensor triggers a corresponding action and sends a command to the control box assembly to switch the faucet's water outlet mode when the first sensor triggers the sensing, the faucet's water outlet mode when the second sensor triggers the sensing, and the faucet's water outlet mode when the third sensor triggers the sensing.

[0008] As a further improvement, the sensing component also includes a mounting section embedded in the water outlet of the faucet housing, with the first sensor fixed at the bottom of the mounting section and the second and third sensors fixed on the left and right sides of the mounting section, respectively.

[0009] As a further improvement, a pull-out head and a water purification pipe are installed inside the faucet housing; the sensing component also includes an installation section that is embedded in the water outlet of the faucet housing and makes way for the pull-out head, and a cover section is snapped into the water outlet of the faucet housing, the cover section having a groove for the installation section to be embedded in; a positioning hole opened on the installation section and a through hole opened on the cover section are provided for the water outlet end of the water purification pipe to pass through and be accommodated.

[0010] As a further improvement, the sensor windows on the left and right sides of the cover section are hollow inside to accommodate the second or third sensor, and through holes are opened on the periphery of the faucet housing for the sensor windows to extend out, with the end face of the sensor window flush with the side of the faucet housing.

[0011] As a further improvement, the bottom plate of the cover section is welded to the water outlet of the faucet housing so that the lower end face of the cover section is flush with the bottom end of the water outlet of the faucet housing.

[0012] As a further improvement, several reinforcing ribs are provided between the base plate and the periphery of the cover section to enhance the structural strength.

[0013] As a further improvement, the control box assembly includes a solenoid valve for controlling the on / off of the faucet's water flow. The two inlet ports of the solenoid valve are respectively connected to a cold water pipe and a hot water pipe. The pull-out head is connected to the outlet port of the solenoid valve via a flexible hose. When the first sensor detects that a hand is close to the bottom of the water outlet and the distance between the hand and the hand is less than the sensing threshold, the first sensor triggers an action and sends an immediate water supply command to the control box assembly, causing the solenoid valve to open and supply water into the pull-out head. At this time, the faucet is in the first water outlet mode. When the hand is far away from the bottom of the water outlet and the distance between the hand and the hand is greater than the sensing threshold, the first sensor sends a water shut-off command to the control box assembly.

[0014] As a further improvement, a filter element for filtering water source is provided at the water inlet end of the water purification pipe; the control box assembly includes a solenoid valve for controlling the on / off of the faucet water circuit, and the water purification pipe is connected to the water outlet of the solenoid valve through a flexible hose; the water inlet of the faucet housing is provided with a display component for digitally displaying the faucet water output data, and an adjustment button for adjusting the water output of the water purification pipe is provided on the end face of the display component.

[0015] When the second sensor detects a hand approaching the left-side sensor window of the water outlet and the distance between the hand and the sensor is less than the sensing threshold, the second sensor triggers an action and sends an immediate water supply command to the control box assembly, causing the solenoid valve to open and output filtered water quantitatively into the water purification pipe. At this time, the faucet is in the second water outlet mode. When the hand approaches the left-side sensor window of the water outlet again, the second sensor sends a water shut-off command to the control box assembly.

[0016] As a further improvement, the control box assembly includes a solenoid valve for controlling the on / off of the faucet's water flow. The two inlets of the solenoid valve are connected to a cold water pipe and a hot water pipe, respectively. When the third sensor detects a hand approaching the right-side sensor window of the water outlet and the hand's distance is less than the sensing threshold, the third sensor triggers an action and sends an immediate water supply command to the control box assembly. The two inlets of the solenoid valve open simultaneously, allowing the water flow in the cold water pipe and the hot water pipe to mix to form warm water, which is then periodically supplied to the pull-out head. At this time, the faucet is in the third water outlet mode. When the hand approaches the right-side position of the water outlet again, the first sensor sends a water shut-off command to the control box assembly.

[0017] As a further improvement, a Hall switch electrically connected to the control box assembly is installed in a receiving groove inside the installation section. A magnet is embedded inside the pull-out head, which cooperates with the Hall switch to control the water flow from the pull-out head. When the pull-out head is pulled out from the water outlet of the faucet housing, the magnet on the pull-out head moves away from the Hall switch, and the Hall switch sends a signal to the control box assembly to enable the faucet to release water. When the pull-out head returns to its original position, the Hall switch senses the displacement of the magnet and sends a water shut-off command to the control box assembly.

[0018] The beneficial effects of this utility model are:

[0019] This application features a first sensor at the bottom of the faucet outlet, and a second and third sensor on the left and right sides, allowing users to make personalized selections based on their actual needs for using the three faucet water outlet modes. It has the advantages of simple structure and convenient operation. Attached Figure Description

[0027] The structure of each component of this utility model will be described below.

[0028] like Figures 1-5 As shown, a faucet that facilitates switching of water outlet modes includes a faucet housing 10, a sensing component 20 built into the water outlet 101 of the faucet housing 10, and a control box assembly 30 electrically connected to the sensing component 20 to switch the faucet water outlet modes. The sensing component 20 includes a first sensor 21 disposed on the bottom surface of the water outlet 101 of the faucet housing 10, a second sensor 22 disposed on the left and right sides of the water outlet 101 of the faucet housing 10, and a third sensor 23 disposed on the left and right sides of the water outlet 101 of the faucet housing 10. Each sensor can identify and collect the distance of a hand approaching the user. When the distance is lower than the sensing threshold, each sensor triggers a corresponding action and sends a command to the control box assembly 30 to achieve the switching of water outlet modes: when the first sensor 21 triggers the sensing, the faucet is in the first water outlet mode; when the second sensor 22 triggers the sensing, the faucet is in the second water outlet mode; and when the third sensor 23 triggers the sensing, the faucet is in the third water outlet mode.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 3 and Figure 4 As shown, a pull-out head 40 and a water pipe 50 are installed inside the faucet housing 10. The sensing component 20 also includes a mounting section 24 embedded in the water outlet 101 of the faucet housing 10 and giving way to the pull-out head 40. The first sensor 21 is fixed at the bottom of the mounting section 24, and the second sensor 22 and the third sensor 23 are fixed on the left and right sides of the mounting section 24, respectively. A cover section 25 is snapped into the water outlet 101 of the faucet housing 10. The cover section 25 has a groove 251 for the mounting section 24 to be embedded in. This design allows the mounting section 24 to be built into the cover section 25, preventing water or other dust from entering or adhering to the sensor surface during daily use and affecting its normal use, thus protecting the sensor. It should be noted that all sensors in this application are infrared sensors.

[0031] like Figures 2-4As shown, the bottom plate 252 at the bottom of the cover section 25 is corrugated and welded to the outlet 101 of the faucet housing 10, so that the lower end face of the cover section 25 is flush with the bottom end of the outlet 101 of the faucet housing 10. Several reinforcing ribs 253 are provided between the bottom plate 252 and the periphery of the cover section 25 to enhance the structural strength. The sensor windows 254 on the left and right sides of the cover section 25 are hollow inside to accommodate the second sensor 22 or the third sensor 23. Through holes 11 are opened on the periphery of the faucet housing 10 for the sensor windows 254 to extend out. The end face of the sensor window 254 is flush with the side of the faucet housing 10. This design ensures that after the second sensor 22 and the third sensor 23 are installed, their installation positions can remain flush with the faucet housing 10, so that the sensors can more accurately capture human hand movements, and also make the surface of the faucet housing 10 smooth and clean, improving the aesthetics of the overall structure.

[0032] like Figures 1-5 As shown, the positioning hole 241 on the mounting section 24 and the through hole 255 on the cover section 25 allow the outlet end of the water purification pipe 50 to pass through and be accommodated. A filter element (not shown in the figure) for filtering the water source is provided at the inlet end of the water purification pipe 50. The control box assembly 30 includes a solenoid valve (not shown in the figure) for controlling the on / off of the faucet water circuit. The solenoid valve used in this application is a pulse-type bistable solenoid valve. The pull-out head 40 and the water purification pipe 50 are respectively connected to the two outlet holes of the solenoid valve through flexible hoses. The two inlet holes of the solenoid valve are respectively connected to the cold water pipe 100 and the hot water pipe 110. A pull-out head 40 has a protruding operating handle 41 on its circumference. A sliding groove 12 is provided on the side wall of the faucet housing 10 at the water outlet 101 to allow the operating handle 41 to slide. In actual use, the user can easily remove the pull-out head 40 from the faucet housing 10 by pulling the operating handle 41 for subsequent use. It should be noted that the pull-out head 40 is assembled with the hose by a threaded connection. After the external force is removed, the pull-out head 40 will automatically return to the faucet housing 10. The relevant structure and operating principle are existing technologies and will not be described in detail here.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the faucet housing 10 includes an integrally formed riser section 13 and a bend section 14. The water outlet 101 of the faucet housing 10 is located at the bottom end of the bend section 14, and the water inlet 102 is located at the bottom end of the riser section 13. A display component 60 for digitally displaying faucet water output data is provided on one side of the water inlet 102 of the riser section 13, and an operation switch 70 for manually turning on the faucet water circuit is provided on the other side. It is worth noting that the functions that the display component 60 can realize include, but are not limited to: screen lighting, page jumping, and display of water output information (flow rate, flow velocity, water output time, temperature, etc.). An adjustment button 61 for adjusting the water output of the water purifier pipe 50 is provided on the end face of the display component 60.

[0034] like Figure 4 As shown, a Hall switch 80 electrically connected to the control box assembly 30 is installed in the receiving groove 242 opened inside the installation section 24. A magnet 90 is embedded inside the pull head 40, which is magnetically coordinated with the Hall switch 80 to control the water output of the pull head 40. When the pull head 40 is pulled out from the water outlet 101 of the faucet housing 10, the magnet 90 on the pull head 40 moves away from the Hall switch 80. The Hall switch 80 sends a signal for the water output of the pull head 40 and distributes it to the display assembly 60 and the control box assembly 30, realizing the interactive operation of the solenoid valve to turn on the water and the display assembly 60.

[0035] The following is combined Figures 1-5 This section details the working principle of each water outlet mode of this utility model.

[0036] When the first sensor 21 detects that a hand is close to the bottom of the water outlet 101 and the distance between the hand and the hand is less than the sensing threshold, the first sensor 21 triggers an action and sends an instant water supply command to the display component 60 and the control box component 30, causing the solenoid valve to open and supply water into the pull-out head 40, thereby realizing the interactive operation of instant faucet water supply and display component 60. At this time, the faucet is in the first water supply mode. When the hand is far away from the bottom of the water outlet 101 and the distance between the hand and the hand is greater than the sensing threshold, the first sensor 21 sends a water shut-off command to the control box component 30.

[0037] When the second sensor 22 detects that a hand is close to the left sensor window 254 of the water outlet 101 and the distance between the hand and the sensor is less than the sensing threshold, the second sensor 22 triggers an action and sends an instant water supply command to the display component 60 and the control box component 30, causing the solenoid valve to open and output filtered water quantitatively into the water purification pipe 50. At this time, the faucet is in the second water outlet mode. When the hand is close to the left sensor window 254 of the water outlet 101 again, the second sensor 22 sends a water shut-off command to the control box component 30.

[0038] When the third sensor 23 detects that a hand is close to the right side of the water outlet 101 and the distance between the hand and the sensor is less than the sensing threshold, the third sensor 23 triggers an action and sends an instant water supply command to the display component 60 and the control box component 30. The two inlets 102 of the solenoid valve open simultaneously, so that the water in the cold water pipe 100 and the hot water pipe 110 mixes to form warm water, and then delivers the mixed warm water to the pull-out head 40 at regular intervals. At this time, the faucet is in the third water outlet mode. When the hand is close to the right side of the water outlet 101 again, the first sensor 21 sends a water shut-off command to the control box component 30.

[0039] When the pull-out head 40 is pulled out from the water outlet 101 of the faucet housing 10, the magnet 90 on the pull-out head 40 moves away from the Hall switch 80. The Hall switch 80 sends a signal to the control box assembly 30 to make the faucet pull-out head 40 release water. When the pull-out head 40 is reset, the Hall switch 80 senses the displacement of the magnet 90 and sends a water shut-off command to the control box assembly 30.

[0040] It should be noted that the water dispensing mode of this application is not limited to the three listed above. In other embodiments, the function of automatically dispensing soap can also be achieved by installing a soap dispenser inside the faucet housing 10. Users can make personalized selections and installations of the internal components of the faucet housing 10 according to their actual usage needs.

[0041] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various modifications or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention, as defined by the claims.
