Description

Technical Field

[0001] This utility model relates to a multifunctional sensor-operated water tap. Background Technology

[0002] Most commercially available faucets with both purified water and tap water outlet modes typically use the same delivery pipe for both. For example, Chinese patent application number CN201610669037.2 describes a faucet that switches between purified water and tap water. In this case, both the tap water pipe 20 and the purified water pipe 21 are transported through an inner purified water pipe 16. After prolonged use, trace substances in the tap water will form scale on the inner wall of the inner purified water pipe 16. When the purified water function is used, the filtered water will flush out some of the scale from the inner wall of the inner purified water pipe 16, causing problems such as purified water contamination. Utility Model Content

[0003] This invention provides a multifunctional sensor-operated water faucet that can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A multi-functional sensor-operated faucet includes a faucet housing, a pull-out head for dispensing tap water and a water purification pipe for dispensing filtered water installed inside the faucet housing; a sensor component installed inside the water outlet of the faucet housing and a control box assembly electrically connected to the sensor component to switch the faucet's water dispensing mode; a filter element for filtering the 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 state of the faucet's water flow.

[0006] The sensing components include a first sensor located on the bottom surface of the faucet housing's water outlet and a second sensor located on one side of the faucet housing's water outlet. 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. The pull-out head and the water purification pipe are connected to the two water outlets of the solenoid valve via flexible hoses. When the first sensor is triggered, the solenoid valve opens and supplies water to the pull-out head, putting the faucet in the first water outlet mode (pull-out head). When the second sensor is triggered, the solenoid valve opens and supplies water to the water purification pipe, putting the faucet in the second water outlet mode (water purification pipe).

[0007] The solenoid valve is a pulse-type bistable solenoid valve.

[0008] The sensing component also includes a mounting section embedded in the water outlet of the faucet housing and giving way to the pull-out head. The first sensor is fixed at the bottom of the mounting section, and the second sensor is fixed on the left side of the mounting section.

[0009] A cover section is snapped into the water outlet of the faucet housing. The cover section has a groove for the installation section to be embedded in. The sensor windows on the left and right sides of the cover section are hollow inside to accommodate the second sensor.

[0010] The mounting holes on the installation section and the perforations on the cover section allow the outlet end of the water purification pipe to be installed.

[0011] A handle is formed by a protrusion around the pull-out head, and a sliding groove is provided on the side wall of the faucet housing at the water outlet to allow the handle to slide.

[0012] The faucet housing includes an integrally formed riser section and a bend section. The water outlet of the faucet housing is located at the bottom end of the bend section, and the water inlet is located at the bottom end of the riser section. On one side of the water inlet of the riser section, there is a display component for digitally displaying the faucet's water output data, and on the other side, there is an operation switch for manually turning on the faucet's water circuit.

[0013] An adjustment button for adjusting the water flow rate from the water purifier is provided on the end face of the display component.

[0014] A Hall switch electrically connected to the control box assembly is installed in a receiving slot inside the installation section, and a magnet is embedded inside the pull-out head to control the water flow from the pull-out head in conjunction with the magnetic induction of the Hall switch.

[0015] The beneficial effects of this utility model are:

[0016] The present application provides a pull-out head for tap water and a purified water pipe for filtered water, which are respectively connected to a solenoid valve via flexible hoses. A filter element for filtering the water source is installed at the inlet end of the purified water pipe, thereby enabling the tap water circuit and the purified water circuit to output water independently, so as to avoid the situation of the two water outlets sharing a water supply pipe and causing purified water pollution. Furthermore, the water output mode is switched by sensing and controlling with a first sensor and a second sensor, which is easy to operate. Attached Figure Description

[0024] The structure of each component of this utility model will be described below.

[0025] like Figures 1-5 As shown, a multi-functional sensor-operated faucet includes a faucet housing 10, a pull-out head 40 for dispensing tap water and a water purification pipe 50 for dispensing filtered water, both installed inside the faucet housing 10; a sensor component 20 is built into the water outlet 101 of the faucet housing 10, and a control box assembly 30 is electrically connected to the sensor component 20 to switch the faucet's water dispensing mode. A filter element (not shown) for filtering the water source is provided at the water inlet end of the water purification pipe 50; the control box assembly 30 includes a solenoid valve (not shown) for controlling the flow of water through the faucet; the sensor component 20 includes a first sensor located on the bottom surface of the water outlet 101 of the faucet housing 10. Device 21, a second sensor 22 is installed on one side of the water outlet 101 of the faucet housing 10. Each sensor can identify and collect the distance of the 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. The pull-out head 40 and the water purification pipe 50 are respectively connected to the two water outlets of the solenoid valve through flexible hoses. When the first sensor 21 is triggered, the solenoid valve opens and supplies water to the pull-out head 40, and the faucet is in the first water outlet mode of the pull-out head 40. When the second sensor 22 is triggered, the solenoid valve opens and supplies water to the water purification pipe 50, and the faucet is in the second water outlet mode of the water purification pipe 50.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 3 and Figure 4As shown, the solenoid valve used in this application is a pulse-type bistable solenoid valve; 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, the second sensor 22 is fixed on the left side of the mounting section 24, and a third sensor 23 is also provided on the right side of the mounting section 24; a cover section 25 is snapped into the water outlet 101 of the faucet housing 10, and 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, affecting its normal use, and playing a role in protecting the sensor; it should be noted that all sensors in this application are infrared sensors.

[0028] like Figures 2-4 As 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.

[0029] like Figures 1-5 As shown, the positioning hole 241 on the installation 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 pull-out head 40 has a protruding operating handle 41 on its periphery. A sliding groove 12 is provided on the side wall of the faucet housing 10 at the outlet 101 to allow the operating handle 41 to slide and move. 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 and the hose are assembled 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 technology, so they will not be described in detail here.

[0030] like Figure 1 , Figure 2 and Figure 5As 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 display component 60 can realize functions including but not limited to: screen lighting, page jumping, display of water output information (flow rate, flow velocity, water output time, temperature, etc.), historical setting records, mixed temperature water information, and purified water information. An adjustment button 61 for adjusting the water output of the purified water pipe 50 is provided on the end face of the display component 60.

[0031] It should be noted that the display component 60 of this application has WiFi networking capabilities, mainly achieved through IoT application communication, supporting TCP / IP, UDP, MQTT protocols, etc.; and the display component 60 has a built-in BLE low-power Bluetooth module with one master and multiple slaves, which allows the faucet to act as a master to pair with multiple slave devices (such as remote controls, garbage disposers, soap dispensers, hand dryers), or as a slave to pair with other masters (such as mobile phones, Bluetooth speakers, smart home control boxes, etc.), realizing more interactive functions.

[0032] 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, realizing the interactive operation of the solenoid valve opening water and the display assembly 60.

[0033] The following is combined Figures 1-5 This section details the working principle of each water outlet mode of this utility model.

[0034] 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 outlet mode.

[0035] When the second sensor 22 detects that a hand is close to the left sensing window 254 of the water outlet 101 and the distance between the hand and the sensing threshold 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 supply water into the water purification pipe 50. At this time, the faucet is in the second water outlet mode.

[0036] When the third sensor 23 detects that a hand is close to the right sensor window 254 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 water inlets 102 of the solenoid valve open simultaneously, so that the water flow 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 this time, the faucet is in the third water outlet mode.

[0037] 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.

[0038] 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.
