Description

Technical Field

[0001] This utility model belongs to the field of faucets, specifically a sensor-operated faucet. Background Technology

[0002] Faucets are now an essential item in homes, especially in kitchen sinks and washbasins. To make them more convenient, faucets are equipped with infrared sensor switches that automatically turn on the water when a person is present, allowing users to turn the faucet on and off without operating a physical mechanical switch. However, because infrared sensors are not always stable, users often have to constantly adjust the trigger position to get hot water working each time they want to turn it on. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a sensor-operated water faucet.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A sensor-operated faucet includes a faucet body, which comprises a faucet seat with a water inlet and a water outlet bend located above the faucet seat. The water inlet of the faucet seat is connected to the water outlet within the water outlet bend via an electrically controlled valve. The electrically controlled valve controls the connection and disconnection of the water inlet and outlet. The water outlet bend is equipped with a conductive clamp and has a metal surface that is electrically connected to the conductive clamp. When a human touches the metal surface, the conductive clamp generates an electrical signal, which is transmitted to a wireless signal transmitter. The wireless signal transmitter converts the electrical signal into a radio frequency signal and transmits it. The electrically controlled valve is connected to a wireless signal receiver, which receives the radio frequency signal and converts it into an on / off signal. The electrically controlled valve controls the connection and disconnection of the water inlet and outlet based on the on / off signal data.

[0006] The entire water outlet bend is made of metal, and the entire surface of the water outlet bend constitutes the metal surface.

[0007] The faucet seat is equipped with a mechanical valve, which is connected to the tap water circuit and can control the connection between the inlet water circuit and the tap water circuit.

[0008] The tap water circuit is divided into a cold water circuit and a hot water circuit. The mechanical valve is a mixing valve, which can adjust the water inlet ratio of the cold water circuit and the hot water circuit, thereby controlling the water temperature of the faucet.

[0009] The water outlet bend is rotatably mounted on the top of the faucet seat.

[0010] The conductive clamp is detachably fitted onto the water outlet bend, and the inner ring of the conductive clamp has a conductive surface that makes contact with the metal surface for electrical connection.

[0011] The outlet bend is equipped with an outlet hose to form an outlet water path and connect to the electric control valve.

[0012] A water outlet nozzle is installed at the end of the water outlet bend. The water inlet end of the water outlet nozzle is connected to the water outlet hose. The water outlet nozzle has two or more water outlet ends and an internal switching mechanism to switch between the water outlet ends and the water inlet ends.

[0013] The faucet seat has a tabletop mounting mechanism at its bottom, and the electric control valve is located below the tabletop mounting mechanism.

[0014] The beneficial effects of this utility model are as follows: This utility model utilizes the principle of bioelectricity, and sets a conductive clamp on the water outlet bend of the faucet. When a human body touches the metal surface of the water outlet bend, bioelectricity is conducted to the conductive clamp and forms an electrical signal that is transmitted to the wireless signal transmitter. The wireless signal transmitter converts the electrical signal into a radio frequency signal and transmits it. The electric control valve is equipped with a wireless signal receiver that receives the radio frequency signal and converts it into on / off signal data. The electric control valve controls the connection and disconnection of the inlet and outlet water circuits according to the on / off signal data, thereby realizing the purpose of turning the faucet on or off. The operation process is clear and easy to trigger the faucet to turn on and off, making it very convenient to use. Furthermore, the use of wireless transmission technology eliminates the need for a complex wiring layout inside the faucet, simplifying the structure and greatly increasing safety. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] Reference Figure 1A sensor-activated faucet includes a faucet body 1, which comprises a faucet seat 11 with a water inlet and a water outlet bend 12 positioned above the faucet seat 11. The water inlet of the faucet seat 11 is connected to the water outlet of the water outlet bend 12 via an electrically controlled valve 2. The electrically controlled valve 2 controls the connection and disconnection of the water inlet and outlet. The water outlet bend 12 is equipped with a conductive clamp 3, and has a metal surface that is electrically connected to the conductive clamp 3. When a human touches the metal surface, the conductive clamp 3 generates an electrical signal, which is transmitted to a wireless signal transmitter 4. The signal transmitting device 4 converts the electrical signal into a radio frequency signal and transmits it. The electric control valve 2 is connected to a wireless signal receiving device 5, which receives the radio frequency signal and converts it into opening or closing signal data. The electric control valve 2 controls the connection and disconnection of the inlet and outlet water circuits according to the opening and closing signal data, so as to realize the purpose of turning the faucet on or off. The user's operation process is clear and easy to trigger the faucet to turn on and off, which is very convenient to use. Just touch the metal surface of the outlet bend 12. In addition, wireless transmission technology is adopted, and there is no need to arrange complex wires inside the faucet. The structure is simplified and the safety is greatly increased.

[0018] As a preferred embodiment of this utility model, the water outlet bend 12 is entirely made of metal, and the entire surface of the water outlet bend 12 constitutes the metal surface. That is, the user can control the faucet to open or close the water flow by touching any part of the surface of the water outlet bend 12. The faucet seat 11 is also provided with a mechanical valve 13. The mechanical valve 13 is connected to the tap water circuit and can control the connection between the inlet water circuit and the tap water circuit. It can also be used as an emergency valve. Under normal circumstances, the mechanical valve 13 is in the open state. When the conductive clamp 3 is damaged, causing the inductive switch to fail, or when the electric control valve 2 is damaged and cannot close the water flow, the water flow of the faucet can be closed or opened through the mechanical valve 13, so that the faucet can still be used normally.

[0019] As a preferred embodiment, the tap water circuit is divided into a cold water circuit 61 and a hot water circuit 62. The mechanical valve 13 is a mixing valve, which can adjust the ratio of water entering the cold water circuit 61 and the hot water circuit 62 to control the water temperature of the faucet.

[0020] Preferably, since wireless signal transmission is used, no wires are needed inside the faucet body 1. Therefore, the water outlet bend 12 is rotatably mounted on the top of the faucet seat 11, allowing for easy adjustment of the water outlet position without being limited by the internal structure. Furthermore, the water outlet bend 12 contains a water outlet hose 7 to form a water path and connect to the electronically controlled valve 2. This simplifies the water path structure, reduces cost, and allows for the addition of more water outlet functions. Even further, a water outlet nozzle 15 is installed at the end of the water outlet bend 12. The inlet end of the water outlet nozzle 15 is connected to the water outlet hose 7. The water outlet nozzle 15 has two or more outlets and an internal switching mechanism to switch between the inlet and outlet ends. The number of inlet ends can also be adjusted according to the number of water outlet hoses 7. For example, one water outlet hose 7 can be connected to tap water, and another can be connected to purified water. In this case, the water outlet nozzle 15 also has corresponding tap water outlets and purified water outlets.

[0021] Preferably, the conductive clamp 3 is detachably fitted onto the water outlet bend 12. The conductive clamp 3 has a conductive surface on its inner ring that makes contact with the metal surface for electrical connection, thus completing the arrangement of the conductive clamp 3. This form allows the installation of the sensor faucet of this utility model by equipping an ordinary faucet with the aforementioned conductive clamp 3 and the electric control valve 2, which is beneficial for upgrading older products. Specifically, the bottom of the faucet seat 11 is provided with a countertop mounting mechanism 14 for installation on a washbasin or kitchen sink, while the electric control valve 2 is located below the countertop mounting mechanism 14, that is, installed below the washbasin or kitchen sink, without being exposed and affecting the appearance of the faucet.
